The National Longitudinal Study of Adolescent Health data were used to test predictions from life history theory. We hypothesized that (1) in young adulthood an emerging life history strategy would exist as a common factor underlying many life history traits (e.g., health, relationship stability, economic success), (2) both environmental harshness and unpredictability would account for unique variance in expression of adolescent and young adult life history strategies, and (3) adolescent life history traits would predict young adult life history strategy. These (...) predictions were supported. The current findings suggest that the environmental parameters of harshness and unpredictability have concurrent effects on life history development in adolescence, as well as longitudinal effects into young adulthood. In addition, life history traits appear to be stable across developmental time from adolescence into young adulthood. (shrink)

Shared genetic inheritance results in a high correlation in the heights of brothers, but experiences in childhood and adolescence can intervene. Poor diet, disease, and heavy labor can prevent the achievement of height potentials. If families cannot control variations in these conditions, the heights of brothers will be less strongly correlated. We use heights measured at military conscription examinations from three communities in nineteenth-century Belgium. The Generalized Estimating Equation procedure allows us to estimate effects of covariates on mean heights as (...) well as the correlations within families. Both average height and the correlation of brothers’ heights differed by socioeconomic status. Members of the local elite were taller and the heights of brothers in those families were more strongly correlated. This suggests that elite families were much better able to control the environmental challenges faced by their offspring. (shrink)

Restoration involves individuals’ physical, psychological and social resources, diminished by meeting demands of everyday life. Psychological restoration can be provided by specific environments, in particular by natural environments. Research reports a restorative effect of nature on human beings, specifically in terms of the psychological recovery from attention fatigue and restored mental resources previously spent in activities that require attention. Two field studies in two Italian primary schools tested the hypothesized positive effect of recess-time spent in a (...) natural (vs. built) environment on pupils’ cognitive performance and their perceived restorativeness, using standardized tests. In Study 1, children’s psychological restoration was assessed measuring sustained and selective attention, working memory, and impulse’ control, before and after morning recess-time. Team standardized play-time was conducted in a natural (vs. built) environment, measuring perceived restorativeness after each recess-time. Results showed a greater increase in sustained and selective attention, concentration, and perceived restorativeness from pre-test to post-test after the Natural Environment condition. In Study 2 the positive effect of free-play recess-time in a natural (vs. built) environment was assessed during the afternoon school-time on sustained and selective attention and perceived restorativeness. Results showed an increase of sustained and selective attention after the Natural Environment condition (vs. Built) and a decrease after the built environment break. Higher scores in perceived restorativeness were registered after the Natural (vs. Built) Environment condition. Team standardized and individual free-play recess in a natural environment (vs. built) support pupils’ attention restoration during both morning and afternoon school-time, as well as their perceived restorativeness of recess environment. Theoretical and practical implications are discussed in terms of nature’s role both for school ground design or re-design, and for school’s activities organization. (shrink)

Purpose: Empirical studies suggest that corporate social responsibility impacts young job seekers’ choices of an employer. Values seem to affect CSR preferences, influencing the felt fit between the person and the organization and hereby the valence of working for that company. This article aims to research in more detail the preference structure of young graduate job seekers. In particular, it seeks to understand whether CSR is important when there is a trade-off between CSR and non-CSR attributes and whether basic value (...) orientations of job seekers have a moderating effect on their employer preferences. Design/methodology/approach: This article used a quantitative approach with a survey sample of 577 German students who were in their last year of study. To gain information on the relative impact of CSR- and non-CSR-related employer characteristics on employer attractiveness, an adaptive conjoint analysis was applied. Correlation analysis and a two-step hierarchical regression were conducted to detect the effects of individual value orientations. Findings: Only a few CSR attributes are relevant for young job seekers compared with other traditional employer attributes. Specific value orientations can be identified as having a moderating effect on CSR preferences. This is particularly the case for value orientations indicating a concern for the welfare of others and the environment positively affect the importance of most CSR attributes while more selfish value orientations have a negative effect. Originality/value: This study sheds light on the relative importance of CSR attributes when compared with non-CSR attributes. Moreover, it relates employee-related preferences to individual value orientations and shows that selected values have a modifying effect on the importance of CSR for job choice. (shrink)

A radical approach to the environment which argues that by harnessing the power of science for human benefit, we can have a healthier planet As a prizewinning theoretical physicist and an outspoken advocate for scientific literacy, James Trefil has long been the public's guide to a better understanding of the world. In this provocative book, Trefil looks squarely at our environmental future and finds-contrary to popular wisdom-reason to celebrate. For too long, Trefil argues, humans have treated nature as (...) something separate from themselves-pristine wilderness to be saved or material resources to be exploited. What we need instead is a scientific approach to the environment that embraces the human transformation of nature for our benefit. In Human Nature , Trefil exposes the benefits of genetically modified species, uncovers vital facts about droughts and global warming, and points to examples of environmental management where catering to humans reaps greater rewards than sheltering other species. By taking advantage of explosive advances in the sciences, we can fruitfully manage the planet, if we rise to the challenge. Like Rachel Carson's Silent Spring and Paul Ehrlich's Population Bomb, Human Nature promises to fundamentally alter the way we perceive our relationship to the Earth-but with optimism rather than alarm.

Human capital and ICT have a significant role in determining human development. The impacts of ICT and human capital on green growth and environmental sustainability should be explored for sustainable economic development. This research contributes to the literature on the role of ICTs and human capital in the determination of green growth and environmental performance. Based on time-series data 1990–2019, the study intends to investigate the impact of ICTs and human capital on environmental and green (...) growth performance for China. The study reports that ICTs tend to reduce CO2 emissions and improve green growth in the long-run. However, education reduces CO2 emissions in the long-run but does not produce any significant impact on green growth in the long-run. It is suggested that government should invest in environmental efficiency and environmental technologies simultaneously with human capital that could significantly contribute to pollution reduction. Lastly, policies to increase human capital should be implemented simultaneously with policies to promote ICTs contribution in order to confirm green growth and environmental protection. (shrink)

While living a life based on universal principles is well accepted by many, the reality of living acts as a great detriment to those who want to centre their lives on these timeless truths. Further, institutional mechanisms and work environments do not conform in general to such principle-centred living. The agents of the state, especially those in the police, have to work under tremendous obstacles and pressures from within and without, and often get a bad reputation, sometimes undeservingly. Moreover their (...) value systems may also degrade in these environments, a direction that requires to be altered by the ‘guardians of the law’. It is important to bring about alignment of values and ethical perceptions of state administrators with some universal laws. The Buddhist practice of vipassana mediation can play a significant role in such transformations, as is evident from the responses from Delhi Police personnel who underwent vipassana in one of their training programmes. Vipassana has made significant differences in the lives and perceptions of these trainees—both at the professional and personal level. This paper introduces these concepts and cites evidences from the feedback sheets of trainees to recommend worldwide adoption of such practices for those who occupy seats of power and responsibility. The feedback shows positive and very encouraging trends in all dimensions—work related, humanitarian, family and self—in other words, in professional, personal and deep inner lives. (shrink)

As social animals, humans need to live in groups. This contact with conspecifics is essential for their evolution and survival. Among the recommendations to reduce transmission of the new coronavirus responsible for COVID-19 are social distancing and home confinement. These measures may negatively affect the social life and, consequently, the emotional state and eating behavior of individuals. We assessed the impact of the COVID-19 pandemic on the anxiety, premenstrual symptoms, and eating behavior of young women. Data collection was conducted in (...) person and online. A total of 71 participants, average age of 21.26 years, took part in the study. Trait anxiety during the pandemic was significantly lower than in the prepandemic period. Investigation of the “anxiety/stress” symptom of the Premenstrual Symptoms Screening Tool revealed that this symptom was more severe before the pandemic. There was a decline in the desire for sweet and fatty foods during the pandemic. However, craving for traditional foods rose significantly in the same period. Uncontrolled and emotional eating were significantly lower during the pandemic. The results suggest that the pandemic may have had a positive impact on anxiety and eating behavior of the participants, which may be due to differences between urban and rural populations and the latter living with their families. These findings are important for raising a discussion regarding the effects of the current environment on the regulation of cognitive and dietary adaptations. (shrink)

Nowadays, some of the things that are ḥarāmto be consumed, such as lard, its derivatives and alcohol are used as additives or additional nutrients in products, namely food and cosmetics that people use widely in daily life. The provision of these products, which are accepted as najis(impure), stands in front of us as one of the actual fiqh problems. In order to produce an accurate solution in this regard, the reaction condition and the level of dissolution in the product must (...) be determined. In this article, the level of mutanajjis (contamination) of the products that najisthings transforms through istihlāk(physical change) and the provision (hukm) of benefits from such things are examined. The research covers the discussions in the classical period regarding the provision of things, which included najāsah(impurity) and underwent physical change as well as the evaluations of contemporary Islamic jurists. The aim of this study is to contribute to the researches, which will be carried out to determine the provision of products containing ḥarāmelements. As the production is carried out on an industrial scale, such studies are important today in terms of the establishment of “ḥalāl” sensitivity and meeting the needs of people who have this sensitivity to learn the provision of such products.SummaryNowadays, in various sectors, especially food, feed, cosmetics, health and clothing industries, for the purposes of reducing the cost of the product, extending the shelf life, making the product more attractive in terms of color, consistency and aroma, many substances are added to the main material. The fact that some of the substances added are ḥarām(forbidden) such as blood, lard, pest, and ethyl alcohol require the subject to be considered in terms of fiqh. It is important to clarify two issues in order to reach a healthy result in the studies aiming to determine the provision (ḥukm) of the products that are mixed with najis(impure) substance. One of them is the determination of the level of istihlāk(physical change) in the mutanajjis(contamination) things. The second is the determination of the basic principles to be used in determining the provision of the things which najāsahhas undergone the physical change in. In this study conducted within the scope of this purpose and method, the hadīthsrelated to two different issues that are directly related to the subject have been evaluated as the basic textual basis. These are narrations about the cleanliness and pollution status of the contaminated water, and about the availability of fats and oils, which the dead mouse is seen in. It is stated in the narrations about the condition of the water that najāsah involved in, the water will not be najisunless its smell, taste or color changes because of the falling najāsahin it. According to this hadith, which shows the change of description as a measure, the fuqahāʾ(jurists) came to a consensus on the fact that water, which one of its characteristics changed because of najāsahwould be considered mutanajjis. When thishadithis evaluated together with the narrations that indicate the small amount of water is contaminated because of najāsah, in fact, it is seen that while the water is considered to be clean-najis, the situation of the water being affected from najāsahis taken as the basis and aimed to protect human health against the dirty water. At the time when there were not any one of today's microbiological analysis laboratories, the way to understand the pollution status of water was to see if the smell, color and taste of the water changed while taking the amount of the water into account. Since the rate of foreign matter in the water, the level of pollution and the health status of the water can be determined correctly in the laboratory today, operating the modern techniques as well as the measure of qualification change will be appropriate for the purpose of the hadīthsmentioned.In the narrations about the state of the fat, which the dead mouse is found in, it is seen that different operations are requested depending on the fat being solid or liquid. If the fat is liquid, different instructions have been made such as its being poured or used in lighting. Mālikīs, Shāfiʿīs, and Ḥanbalīfaqīhs (jurists) of the first period have ruled that liquids such as vinegar, milk and honey are mutanajjis, whether they are in little quantity or not, and whether their descriptions are changed or not, claiming that the amount of oil and the degree of impact on the dirt is not declared in the hadīths. The Ḥanafīs adopted the provision in the narrations mentioned pointing to a small amount of liquid oil and considered the measure of description change for a large amount of liquid valid. Ẓāhirīs, Ibn Taymiyyah and some of the faqīhsargued that the liquids which one cannot feel the color, taste or smell of the najāsahin are clean, regardless of the amount.These three approaches are open to criticism because the first is limited only to the literal meaning in the narrations and neglects the aims, and the second ignored the non-water fluids’ ability to hide the descriptions of the substance added to them, and the third evaluates the mustahlak substance (that has undergone a physical change) as if it had been istiḥālah(chemically changed). When the narrations related to the subject are examined, it is understood that while the usage of the liquid fat which the dead mouse was seen in as the food was prohibited, in fact, it was based on the foresight that all of the fat is affected by the mouse. It appears to have been ruled out that only the part polluted is the part affected by thenajāsahfor the fact that after the removal of the mouse and the environment from the solid oil exposed to the same contamination, the rest is allowed to be eaten. According to this, it is possible to say that the measure of mutanajjisin the things that affected by najāsahis in the degree of spreading of najāsah.Nowadays it is possible to determine the presence of najisthings in the main material, which is used as additive or addition, by the level of effect of these substances in the product, as well as by the assays. If the najissubstances used for purposes such as brightness, taste, consistency and extending shelf life, perform the expected functions, it means that they protect their presence in the product effectively. In fact, it should be acknowledged that these substances continue to exist effectively in the product, if they perform the targeted function without any chemical change, even the ratio in the product is low or the color, taste and odor are eliminated during the mixture.The faqīhswhile differed in opinion about the mutanajjisof things that the najāsahhad undergone physical changes in, they, in concert, considered the substances, which were not cleaned or could not be cleansed from which that they accept as mutanajjisby their own measurements, khabīs(disgusting), and have accepted the people’s eating of them as ḥarām. Likewise, they did not allow such things to be used in any way touching the body, clothing and containers. They have evaluated the narrations, which requires the spilth the fat that the dead mouse was seen in, as the main basis in this issue. On the other hand, about the use of the mutanajjisthings outside the human consumption area and in such a way that the clothes and body would not be contaminated; the majority of thefaqīhs preferred the mubāḥ provision. They have put forth the narrations as the basis that recommends the usage of the liquid oil in which the mouse was fallen in lighting. These approaches of the fuqahāʾabout the effect of the istihlākon the provision of making use of the things that affected by najāsahare of worth as the basic principles on the subject. It is possible to say that it is not permissible to consume food products containing lard or pork gelatin, and the chicken that has been torn apart while being left in hot water in order to pluck its feathers, and the egg which becomes mutanajjisfor it is boiled up with thenajāsahon, and the using of cosmetic products containing lard when today’s industrial products are evaluated in accordance with these principles. If taken the general opinion that defends that the ethyl alcohol is najis as the basis, the carbonated soft drinks, which are added to alcohol, can also be evaluated in this context. (shrink)

There is a consensus among scientists that climate change is an existing, growing, and human-made threat to our planet. The topic is a divisive issue worldwide, including among people of faith. Little research has focused on the relationship between (non)religious belief and climate change. Hence, in Studies 1 and 2, the authors explore the impact of religious/non-religious orientations: intrinsic (religion as an end in itself), extrinsic (religion as a means to an end), quest (a journey toward religious understanding), and (...) non-religious orientation (i.e., atheistic) on consumer attitudes toward the environment, focusing on recycling advertisements with (non)religious cues. Further, in Study 3, we examine the underlying causal mechanism of environmental identity and the moderating effect of political views on consumers’ lack of belief in climate change. The results show that religious people are less committed to the environment and climate change and that atheism positively affects recycling and climate change identity. The findings offer practical implications in that advertising campaigns need to be endorsed by religious leaders and channeled within the confines of the religious institutions they represent.

The COVID-19 pandemic has created enormous challenges for organizations and employees. Due to the effectiveness of idiosyncratic deals in management practices, more and more organizations use this human resource management tool to address the challenges posed by the COVID-19 pandemic. However, whether there are potential risks or negative effects of i-deals in the COVID-19 pandemic environment is not very clear. Drawing upon social cognitive theory, we proposed that i-deals may foment focal employees’ unethical behavior by triggering their hubristic (...) pride, and such process may be moderated by their trait of grandiose narcissism. We conducted a survey during the COVID-19 outbreak and tested our hypotheses with 492 samples from Shandong Province, China. Consistent with predictions, we found a positive relationship between i-deals and hubristic pride, which, in turn, increased their unethical behavior. And the relationship between i-deals and unethical behavior was mediated by hubristic pride. Furthermore, grandiose narcissism strengthened the positive relationship between i-deals and hubristic pride, as well as the indirect effect of i-deals on unethical behavior via hubristic pride. Our findings contributed to the literature on i-deals and provided guidance for organizations to address the challenges posed by the COVID-19 pandemic. (shrink)

The central nervous system uses feedback processes that occur at multiple time scales to control interactions with the environment. The long-latency response is the fastest process that directly involves cortical areas, with a motoneuron response measurable 50 ms following an imposed limb displacement. Several behavioral factors concerning perturbation mechanics and the active role of muscles prior or during the perturbation can modulate the long-latency response amplitude in the upper limbs, but the interactions among many of these factors had not (...) been systematically studied before. We conducted a behavioral study on thirteen healthy individuals to determine the effect and interaction of four behavioral factors – background muscle torque, perturbation direction, perturbation velocity, and task instruction – on the LLRa evoked from the flexor carpi radialis and extensor carpi ulnaris muscles after velocity-controlled wrist displacements. The effects of the four factors were quantified using both a 0D statistical analysis on the average perturbation-evoked EMG signal in the period corresponding to an LLR, and using a timeseries analysis of EMG signals. All factors significantly modulated LLRa, and their combination nonlinearly contributed to modulating the LLRa. Specifically, all the three-way interaction terms that could be computed without including the interaction between instruction and velocity significantly modulated the LLR. Analysis of the three-way interaction terms of the 0D model indicated that for the ECU muscle, the LLRa evoked when subjects are asked to maintain their muscle activation in response to the perturbations was greater than the one observed when subjects yielded to the perturbations, but this effect was not measured for muscles undergoing shortening or in absence of background muscle activation. Moreover, higher perturbation velocity increased the LLRa evoked from the stretched muscle in presence of a background torque, but no effects of velocity were measured in absence of background torque. Also, our analysis identified significant modulations of LLRa in muscles shortened by the perturbation, including an interaction between torque and velocity, and an effect of both torque and velocity. The time-series analysis indicated the significance of additional transient effects in the LLR region for muscles undergoing shortening. (shrink)

Since ancient times philosophy has dealt with the relation between technology and man. Nowadays this is especially true in the context of the philosophy of technology. Technology is interpreted as an anthropological constant to construct an environment in which man can survive. Acting in the field of technology is to act rationally with a purpose, i.e., in the framework of a means-end relation, and it is employed for coping with experiences (Widerfahrnisse) by means of using tools. Like technology, language (...) can be reconstructed as a symbolic form and thus as a technological means, as a tool so that the employment of metaphors can also be described as an employment of tools. Using technology has effects on man as well as on his self-image. Thus, philosophy of technology creates different ideas of man, which have to become subject to ethical discourses. (shrink)

Lead (Pb) contamination of the environment is an important human health problem. Children are vulnerable to Pb toxicity; it causes damage to the central nervous system and, in some extreme cases, can cause death. Lead is widespread, especially in the urban environment, and is present in the atmosphere, soil, water and food. Pb tends to accumulate in surface soil because of its low solubility, mobility, and relative freedom from microbial degradation of this element in the soil. Lead (...) is present in soil as a result to weathering and other pedogenic processes acting on the soil parent material; or from pollution arising caused by the anthropogenic activities; such as mining, smelting and waste disposal; or through the adoption of the unsafe and unethical agricultural practices such as using of sewage sludge, and waste water in production of vegetable crops or cultivation of vegetables near highways and industry regions. Lead concentrations are generally higher in the leafy vegetables than the other vegetables. Factors affecting lead uptake included its concentration in the soil, soil pH, soil type, organic matter content, plant species, and unsafe agriculture practices. Generally, as Pb concentration increased; dry matter yields of roots, stems and leaves as well as total yield decreased. The mechanism of growth inhibition by lead involve: a decrease in number of dividing cells, a reduction on chlorophyll synthesis, induced water stress to plants, and decreased NO 3 - uptake, reduced nitrate and nitrite reductase activity, a direct effect of lead on protein synthesis, a decrease on the uptake and concentration of nutrients in plants. The strategies to minimize Pb hazard can be represented in: (a) Phytoremediation, through natural plants are able to bio-accumulate Pb in their above–ground parts, which are then harvested for removal such as, using Indian Mustard (Brassica juncea), Ragweed (Ambrosia artemisiifolia), Hemp Dogbane (Apocynum cannabium), or Poplar trees, which sequester lead in its biomass. (b) Good and ethical agricultural practices such as cultivation of vegetables crops as far from busy streets or highways and industry regions as well as nonuse of sewage sludge and waste water in cultivated soils. (c) Increasing the absorptive capacity of the soil by adding organic matter and humic acid. (d) Growing vegetable crops and cultivars with a low potential to accumulate lead, especially in soils exposed to atmospheric pollution. (e) Washing of leafy vegetables by water containing 1 % vinegar or peeling roots, tubers, and some fruits of vegetables before consumption may be an important factor in reducing the lead concentration.

Electroencephalography-neurofeedback has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present study, we (...) tested 61 young healthy adults to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.

Virtual reality enables individuals to be exposed to naturalistic environments in laboratory settings, offering new possibilities for research in human neuroscience and treatment of mental disorders. We used VR to study psychological, autonomic and postural reactions to heights in individuals with varying intensity of fear of heights. Study participants were immersed in a VR of an unprotected open-air elevator platform in an urban area, while standing on an unstable ground. Virtual elevation of the platform elicited robust and reliable psychophysiological (...) activation including increased distress, heart rate, and electrodermal activity, which was higher in individuals suffering from fear of heights. In these individuals, compared with individuals with low fear of heights, the VR height exposure resulted in higher velocity of postural movements as well as decreased low-frequency body sway oscillations. This indicates that individuals with strong fear of heights react to heights with maladaptive rigidity of posture due to increased weight of visual input for balance control, while the visual information is less reliable at heights. Our findings show that exposure to height in a naturalistic VR environment elicits a complex reaction involving correlated changes of the emotional state, autonomic activity, and postural balance, which are exaggerated in individuals with fear of heights.

Although training in self-regulated learning is effective in improving performance, human trainers can reach only a few people at a time. We developed a web-based training for potentially unlimited numbers of participants based on the process model of SRL by Schmitz and Wiese. A prior study observed positive effects on self-reported SRL and self-efficacy. In the present randomized controlled trial, we investigated an improved version of the web-based training, augmented by the application of peer feedback groups. Prospective university students (...) in an online mathematics preparation course were assigned randomly to one of four experimental conditions: Group D, group TD, group TDP, and group C. Complete data was obtained for 136 participants. The learning diary was intended to trigger goal setting, planning, and self-motivation in the morning and reflection in the evening. The web-based training consisted of three lessons with videos, presentations, self-tests, and exercises. In the peer feedback condition, participants were randomly assigned to groups of five persons each and used a bulletin board to discuss pre-defined topics related to the content of the web-based training. Outcome measures included a test of declarative SRL knowledge, an SRL questionnaire, a general self-efficacy scale, log file data, and a mathematics test. Results showed positive effects for the web-based training, particularly when combined with peer feedback on both SRL knowledge and SRL questionnaires, self-efficacy, and on objective time-investment, but not on the mathematics test. The learning diary did not exhibit positive effects. We conclude that additional peer-feedback seems to be a useful supplement to web-based trainings with comparably low organizational costs.

Anthropology is a disciplined inquiry into the conditions and potentials of human life. Generations of theorists, however, have expunged life from their accounts, treating it as the mere output of patterns, codes, structures or systems variously defined as genetic or cultural, natural or social. Building on his classic work The Perception of the Environment, Tim Ingold sets out to restore life to where it should belong, at the heart of anthropological concern. Being Alive ranges over such themes as (...) the vitality of materials, what it means to make things, the perception and formation of the ground, the mingling of earth and sky in the weather-world, the experiences of light, sound and feeling, the role of storytelling in the integration of knowledge, and the potential of drawing to unite observation and description. Our humanity, Ingold argues, does not come ready-made but is continually fashioned in our movements along ways of life. Starting from the idea of life as a process of wayfaring, Ingold presents a radically new understanding of movement, knowledge and description as dimensions not just of being in the world, but of being alive to what is going on there.

Organisations are increasingly involved in what they call ‘ethical dilemmas’, that is, the conditions under which wrongdoing and righteous deeds must be defined once again because the line between right and wrong has blurred more than ever. In general, human beings have special moral characteristics in the individual and personality dimension that shape their thoughts, speech and behaviour. It is possible that the same people in the same position and organisation could be affected differently, and their ideas, speech (...) and behaviour affect the efficiency and effectiveness of the organisation. Ethics can have positive or negative consequences at each organisational level. One of the effective factors on the occurrence of employees’ ethical behaviours is the role of spirituality in the work environment and humility of leaders. The purpose of this study is to investigate the effect of humility of Muslim leaders on the moral behaviours of followers and spirituality at work in Islamic society. The statistical population of the study was 370 Muslim employees of International Islamic University Malaysia. After distributing the questionnaires among the statistical population, 352 questionnaires were returned. The validity of the questionnaires was confirmed by the content validity method, and its reliability was confirmed by Cronbach’s alpha. In this research, the structural equation modeling approach and Amos software were used to analyse the data. All hypotheses were confirmed at a 95% significance level. The results showed that the humility of leaders has a positive and significant effect on spirituality in the workplace and work ethic of followers. Spirituality in the workplace has also a positive effect on employees’ work ethic.Contribution: It is recommended that the officials of organisations should pay attention to spirituality in the workplace and the humility of managers and supervisors towards employees in order to promote work ethics. Further, it can be concluded that organisations can increase the ethical behaviours of employees by promoting the components of organisational spirituality. (shrink)

PurposeWe conducted a driving simulator study to investigate the effects of monitoring intersection cross traffic on gaze behaviors and responses to pedestrians by drivers with hemianopic field loss.MethodsSixteen HFL and sixteen normal vision participants completed two drives in an urban environment. At 30 intersections, a pedestrian ran across the road when the participant entered the intersection, requiring a braking response to avoid a collision. Intersections with these pedestrian events had either no cross traffic, one approaching car from the side (...) opposite the pedestrian location, or two approaching cars, one from each side at the same time.ResultsOverall, HFL drivers made more of cross-traffic on both the blind and seeing sides. They made more numerous and larger gaze scans when they fixated cars on both sides and had lower rates of unsafe responses to blind- but not seeing-side pedestrians. They were more likely to demonstrate compensatory blind-side fixation behaviors when there was no car on the seeing side. Fixation behaviors and unsafe response rates were most similar to those of NV drivers when cars were fixated on both sides.ConclusionFor HFL participants, making more scans, larger scans and safer responses to pedestrians crossing from the blind side were associated with looking at cross traffic from both directions. Thus, cross traffic might serve as a reminder to scan and provide a reference point to guide blind-side scanning of drivers with HFL. Proactively checking for cross-traffic cars from both sides could be an important safety practice for drivers with HFL. (shrink)

ObjectiveProcessing Speed, the ability to perceive and react fast to stimuli in the environment, has been shown to be impaired in children with attention deficit hyperactivity disorder. However, it is unclear whether PS can be improved following targeted treatments for ADHD. Here we examined potential changes in PS following application of transcranial electric stimulation combined with cognitive training in children with ADHD. Specifically, we examined changes in PS in the presence of different conditions of mental fatigue.MethodsWe used a randomized (...) double-blind active-controlled crossover study of 19 unmedicated children with ADHD. Participants received either anodal transcranial direct current stimulation over the left dorsolateral prefrontal cortex or transcranial random noise stimulation, while completing CT, and the administration order was counterbalanced. PS was assessed before and after treatment using the MOXO-CPT, which measures PS in the presence of various conditions of mental fatigue and cognitive load.ResultstRNS combined with CT yielded larger improvements in PS compared to tDCS combined with CT, mainly under condition of increased mental fatigue. Further improvements in PS were also seen in a 1-week follow up testing.ConclusionThis study provides initial support for the efficacy of tRNS combined with CT in improving PS in the presence of mental fatigue in pediatric ADHD.

The last two centuries have been the centuries of the discovery of the cell evolution: in the XIX century of the germinal cells and in the XX century of two groups of somatic cells, namely those of the brain-mind and of the immune systems. Since most cells do not behave in this way, the evolutionary character of the brain-mind and of the immune systems renders human beings formed by two different groups of somatic cells, one with a deterministic (...) and another with an indeterministic (say Darwinian) behavior. An inherent consequence is that of the generation, during ontogenesis, of a dual biological identity. The concept of the dual biological identity may be used to explain the Kantian concept of the two metaphysical worlds, namely of the causal necessity and of the free will (Azzone, 2001). Two concepts, namely those of complex adaptive systems (CAS) and of emergence (Holland, 2002), are useful tools for understanding the mechanisms of adaptation and of evolution. The concept of complex adaptive systems indicates that living organisms contain series of stratified components, denoted as building blocks, forming stratified layers of increasing complexity. The concept of emergence implies the use of repeating patterns and of building blocks for the generation of structures of increasing levels of complexity, structures capable of exchanging communications both in the top-down and in the bottom-up direction. Against the concept of emergence it has been argued that nothing can produce something which is really new and endowed of causal efficacy. The defence of the concept of emergence is based on two arguments. The first is the interpretation of the variation-selection mechanism as a process of generation of information and of optimization of free energy dissipation in accord with the second principle of thermodynamics. The second is the objective evidence of the cosmological evolution from the Big Bang to the human mind and its products. Darwin has defended the concept of the continuity of evolution. However evolution should be considered as continuous when there is no increase of information and as discontinuous when there is generation of new information. Examples of such generation of information are the acquisition of the innate structures for language and the transition from absence to presence of morality. There are several discontinuity thresholds during both phylogenesis and ontogenesis. Morality is a relational property dependent on the interactions of human beings with the environment. Piaget and Kohlberg have shown that the generation of morality during childhood occurs through several stages and is accompanied by reorganization of the child mental organization. The children respect the conventions in the first stage and gradually generate their autonomous morality. The transition from absence to presence of morality, a major adaptive process, then, not only has occurred during phylogenesis but it occurs again in every human being during ontogenesis. The religious faith does not provide a logical justification of the moral rules (Ayala, 1987) but rather a psychological and anthropological justification of two fundamental needs of human beings: that of rendering Nature an understandable entity, and that of increasing the cooperation among members of the human societies. The positive effects of the altruistic genes in the animal societies are in accord with the positive effects of morality for the survival and development of the human societies. (shrink)

This investigation is intended to explore the effect of the digital environment as well as perfectionism during the COVID-19 pandemic on anxiety and depression. The study used a mixed-methods design; a mixed research methodology was used regarding explanatory design by using a qualitative sub-sample from quantitative sample data. The researcher conducted the study on a sample of 980 students and non-students smartphone and internet users using both qualitative and quantitative approach. Three different questionnaires were used: The Multidimensional Perfectionism (...) Scale, Beck Depression, and Beck Anxiety Inventory. On the other hand, the researcher designed a self-reported interview for the qualitative part that included 5 major questions and 10 sub-questions. The gathered data were investigated using SPSS version 22 to analyze the collected data for this study, and simple descriptive statistics and coding were used. The results denote that the digital environment is significantly correlated with multidimensional perfectionism in a low positive manner for students. However, the correlation effects for non-students are significantly high as evidenced by a significant positive correlation. Another finding suggests that there is a positive significant association between perfectionism and being depressed and anxious. (shrink)

In the process of rapid urbanization, urban heat island effect has been showing more and more significant impacts on human well-being. Therefore, a more detailed understanding of the impact of three-dimensional building morphology on UHI effect across a continuum of spatial scales will be necessary to guide and improve the human settlement.This study selected 31 provincial capital cities of mainland China to analyze the impacts of the 3D building morphology, including the number, area, height, volume, and (...) the surface area of the buildings, on the land surface temperature. By exploring how the influence of 3D building morphology on LST changes with the increase of spatial scale, this study finally recognized which 3D building morphology index is the most significant index affecting LST in different cities, and which spatial scale these 3D building morphology indexes have the most significant impact on LST. The results showed that the building area is the most important 3D building morphology parameter affecting the LST, while the building height has the slightest influence on the LST. These effects are more significant in the spatial scale of 150 m–540 m, and the spatial scale increases with the increase of building areas in developed cities. These results highlight the necessity of considering fine-grained management in the governance and alleviating of the urban thermal environment through urban planning and urban renewal strategies.

Enhancing synchronization among people when synchronization is lacking is believed to improve their social skills, learning processes, and proficiency in musical rhythmic development. Greater synchronization among people can be induced to improve the rhythmic interaction of a system with multiple dancing robots that dance to a drum beat. A series of experiments were conducted to examine the human–human synchrony between persons that participated in musical sessions with robots. In this study, we evaluated: (a) the effect of the (...) number of robots on a subject’s ability to synchronize with an experimenter; (b) the effect of the type of robot synchrony, namely, whether the robots did or did not represent the subject’s rhythm; (c) the effect of an in-sync and out-of-sync robot on a subject’s behavior. We found that: (a) three robots increased the level of synchronization between the subject and experimenter and their enjoyment level; (b) robots may induce greater synchronization between the subject and experimenter by reproducing the rhythms of not only the experimenter but also of the subject compared to when only the experimenter’s rhythms had been reproduced; (c) the robots in-sync had greater influence on the natural rhythm of the subject.

The effects of lexical context on phonological processing are pervasive and there have been indications that such effects may be modulated by attention. However, attentional modulation in speech processing is neither well documented nor well understood. Experiment 1 demonstrated attentional modulation of lexical facilitation of speech sound recognition when task and critical stimuli were identical across attention conditions. We propose modulation of lexical activation as a neurophysiologically plausible computational mechanism that can account for this type of modulation. Contrary to the (...) claims of critics, this mechanism can account for attentional modulation without violating the principle of interactive processing. Simulations of the interactive TRACE model extended to include two different ways of modulating lexical activation showed that each can account for attentional modulation of lexical feedback effects. Experiment 2 tested conflicting predictions from the two implementations and provided evidence that is consistent with bias input as the mechanism of attentional control of lexical activation.

In service marketing, AI assistants and self-service technology have become popular. As a result, it is critical to enrich the understanding of whether consumers react differently in the artificial intelligence service context in comparison with the human service context. This study examines the effect of assistant type on consumers’ decision-making. Through three experiments, this research finds that variety seeking will be higher when consumers are making decision in AI service environment. Furthermore, we tested uncertainty as the underlying (...) mechanism. Moreover, we demonstrated that this pattern is moderated by situational involvement. Specifically, in consumption contexts of high involvement, the consumers are less likely to seek variety, and in consumption contexts of low involvement, they prefer more variety. This research offers service providers new insights by revealing how, why, and when the interaction of AI technology influences consumers’ decision-making in service marketing. (shrink)

The process of urban landmark-based navigation has proven to be difficult to study in a rigorous fashion, primarily due to confounding variables and the problem of obtaining reliable data in real-world contexts. The development of high-resolution, immersive virtual reality technologies has opened exciting new possibilities for gathering data on human wayfinding that could not otherwise be readily obtained. We developed a research platform using a virtual environment and electroencephalography to better understand the neural processes associated with landmark usage (...) and recognition during urban navigation tasks. By adjusting the architectural parameters of different buildings in this virtual environment, we isolated and tested specific design features to determine whether or not they served as a target for landmarking. EEG theta band event-related synchronization/desynchronization over posterior scalp areas was evaluated at the time when participants observed each target building along a predetermined self-paced route. A multi-level linear model was used to investigate the effects of salient architectural features on posterior scalp areas. Our results support the conclusion that highly salient architectural features—those that contrast sharply with the surrounding environment—are more likely to attract visual attention, remain in short-term memory, and activate brain regions associated with wayfinding compared with non-salient buildings. After establishing this main aggregate effect, we evaluated specific salient architectural features and neural correlates of navigation processing. The buildings that most strongly associated extended gaze time, location recall accuracy, and changes in theta-band neural patterns with landmarking in our study were those that incorporated rotational twist designs and natural elements such as trees and gardens. Other building features, such as unusual façade patterns or building heights, were to a lesser extent also associated with landmarking. (shrink)

This study focuses on the effects of socially responsible human resource management practices on female employees’ turnover intentions and the moderating effect of supervisor gender on this relationship. With a sample of 212 female employees from eight different industries in Finland, the results indicate that SR-HRM practices promoting equal career opportunities and work–family integration play a significant role in reducing women's turnover intentions. The study adds to the academic discourse of corporate social responsibility by highlighting the impact of (...) the organizational-level HRM determinants on the individual-level outcome. In addition, supervisor gender makes a difference in the studied relationship: female supervisors have a stronger and more significant impact on the relationship than male supervisors. Our findings suggest that organizational measures which support work–family integration should be taken seriously to decrease female employees’ turnover intentions. Male supervisors could adopt some gender-incongruent leadership behaviors, such as individualized emotional concern and caring when dealing with female employees. In the future, other gender combinations in the supervisor–employee relationship would merit research. (shrink)

Initial moves to develop a new generation of commercial supersonic transports to succeed Concorde are already under way. Aircraft manufacturers promise a plane that will withstand both economic and environmental scrutiny. Yet, the crash of an Air France Concorde at Paris in July 2000 has caused further doubts about the viability of SSTs. This study revisits the previous debate surrounding Concorde to explore the potential for current initiatives to overcome the public’s anxiety of further environmental degradation. This article seeks, therefore, (...) to examine the role that environmental issues and campaign groups played in the development of the first generation of SSTs, concentrating on the influence of global environmental arguments on political decision making. Debate surrounding the global environmental impact of SSTs foreshadows later attention to human impact at the planetary scale. It provides the first illustration of the often complex links between attempted protection of the global environment and political and public perceptions of national vested interests. (shrink)

Emotion has a substantial influence on the cognitive processes in humans, including perception, attention, learning, memory, reasoning, and problem solving. Emotion has a particularly strong influence on attention, especially modulating the selectivity of attention as well as motivating action and behavior. This attentional and executive control is intimately linked to learning processes, as intrinsically limited attentional capacities are better focused on relevant information. Emotion also facilitates encoding and helps retrieval of information efficiently. However, the effects of emotion on learning and (...) memory are not always univalent, as studies have reported that emotion either enhances or impairs learning and long-term memory retention, depending on a range of factors. Recent neuroimaging findings have indicated that the amygdala and prefrontal cortex cooperate with the medial temporal lobe in an integrated manner that affords (i) the amygdala modulating memory consolidation; (ii) the prefrontal cortex mediating memory encoding and formation; and (iii) the hippocampus for successful learning and long-term memory retention. We also review the nested hierarchies of circular emotional control and cognitive regulation (bottom-up and top-down influences) within the brain to achieve optimal integration of emotional and cognitive processing. This review highlights a basic evolutionary approach to emotion to understand the effects of emotion on learning and memory and the functional roles played by various brain regions and their mutual interactions in relation to emotional processing. We also summarize the current state of knowledge on the impact of emotion on memory and map implications for educational settings. In addition to elucidating the memory-enhancing effects of emotion, neuroimaging findings extend our understanding of emotional influences on learning and memory processes; this knowledge may be useful for the design of effective educational curricula to provide a conducive learning environment for both traditional “live” learning in classrooms and “virtual” learning through online-based educational technologies.

Given the importance of the Machiavellianism construct on informing a wide range of ethics research, we focus on gaining a better understanding of Machiavellianism within the whistle-blower context. In this regard, we examine the effect of Machiavellianism on whistle-blowing, focusing on the underlying mechanisms through which Machiavellianism affects whistle-blowing. Further, because individuals who are higher in Machiavellianism (high Machs) are expected to be less likely to report wrongdoing, we examine the ability of an organization’s ethical environment to increase (...) whistle-blowing intentions of high Machs. Results from a sample of 116 MBA students support our premise that Machiavellianism is negatively related to whistle-blowing. Further, we find that Machiavellianism has an indirect effect on whistle-blowing through perceived benefits and perceived responsibility. Finally, we find that a strong ethical environment, relative to a weak ethical environment, increases whistle-blowing intentions incrementally more for individuals who are higher in Machiavellianism. Taken together, these findings extend our understanding of how Machiavellianism and an organization’s ethical environment impact whistle-blowing. (shrink)

Institutions of higher learning have continued to record high cases of gender-based violence (GBV) despite all efforts put in place to fight the vice. The most common forms of GBV are physical, sexual assault and psychological violence. Women and girls make up the majority of the GBV victims worldwide. For many years, institutions of higher learning have proved to be fertile environments for GBV cases. The purpose of this study was to investigate effects of GBV on the well-being of students (...) in institutions of higher learning in Zambia. The study employed a mixed research methodology, and it was anchored on pragmatic philosophical paradigm. An explorative study design was used. Data were collected using both probabilistic and non-probabilistic methods, and the sample size was 150 respondents. The main findings of the study showed both academic and non-academic effects of GBV on students and included stigma, low academic performance, mental and psychological trauma as well as high drop outs. Contribution: The study highlighted effects of GBV as being both academic and non-academic in nature. Once students and staff ignore the word of God spoken in scriptures and begin to follow their egos, the consequences are devastating. For scriptures says love one another, forgive each other and bear each other’s burdens in love. Do unto others as you would want then to do unto you. For where there is love, no one will desire to hurt others. Where there is no love of God or forgiveness, there is pain and damage that can spoil someone’s future, especially that of the youth.

Different housing conditions, including housing space and the physiological and social environment, may affect rodent behavior. Here, we examined the effects of different housing conditions on post-stroke angiogenesis and functional recovery to clarify the ambiguity about environmental enrichment and its components. Male rats in the model groups underwent right middle cerebral artery occlusion followed by reperfusion. The MCAO rats were divided into four groups: the physical enrichment group, the social enrichment group, the combined physical and social enrichment group and (...) the ischemia/reperfusion + standard conditioning group. The rats in the sham surgery group were housed under standard conditions. In a set of behavioral tests, including the modified Neurological Severity Score, rotarod test, and adhesive removal test, we demonstrated that the animals in the enriched condition groups exhibited significantly improved neurological functions compared to those in the standard housing group. Smaller infarction volumes were observed in the animals of the PSE group by MRI detection. The enriched conditions increased the microvessel density in the ischemic boundary zone, as revealed by CD31 immunofluorescent staining. The immunochemical and q-PCR results further showed that environmental enrichment increased the expression levels of angiogenic factors after ischemia/reperfusion injury. Our data suggest that all three enrichment conditions promoted enhanced angiogenesis and functional recovery after ischemia/reperfusion injury compared to the standard housing, while only exposure to the combination of both physical and social enrichment yielded optimal benefits.

IntroductionBisphenol A is highly debated and studied in relation to a variety of health outcomes. This large variation in the literature makes BPA a topic that is prone to selective use of literature, in order to underpin one’s own findings and opinion. Over time, selective use of literature, by means of citations, can lead to a skewed knowledge development and a biased scientific consensus. In this study, we assess which factors drive citation and whether this results in the overrepresentation of (...) harmful health effects of BPA.MethodsA citation network analysis was performed to test various determinants of citation. A systematic search identified all relevant publications on the human health effect of BPA. Data were extracted on potential determinants of selective citation, such as study outcome, study design, sample size, journal impact factor, authority of the author, self-citation, and funding source. We applied random effect logistic regression to assess whether these determinants influence the likelihood of citation.ResultsOne hundred sixty-nine publications on BPA were identified, with 12,432 potential citation pathways of which 808 citations occurred. The network consisted of 63 cross-sectional studies, 34 cohort studies, 29 case-control studies, 35 narrative reviews, and 8 systematic reviews. Positive studies have a 1.5 times greater chance of being cited compared to negative studies. Additionally, the authority of the author and self-citation are consistently found to be positively associated with the likelihood of being cited. Overall, the network seems to be highly influenced by two highly cited publications, whereas 60 out of 169 publications received no citations.ConclusionIn the literature on BPA, citation is mostly driven by positive study outcome and author-related factors, such as high authority within the network. Interpreting the impact of these factors and the big influence of a few highly cited publications, it can be questioned to which extent the knowledge development in human literature on BPA is actually evidence-based.

There are (...) precious lessons to be learned. A global, tangible threat was needed to trigger a global lockdown, where different societies adopted different strategies and management measures to adapt or transform their activities. Humanity is still coming to terms with how to relaunch the economy while preventing further outbreaks. Here, I summarize the immediate positive and negative effects that the pandemic has had on the natural environment, with emphasis on marine ecosystems. I reflect on key lessons learned from this unprecedented situation so far. The essential role that the oceans play in maintaining the functioning of natural systems and key socio-economic activities is exceptionally relevant, and I discuss key not-to-miss opportunities to add the ‘Blue Recovery’ to the international agenda under the new ‘Build Back Better’ or ‘Healthy Recovery’ context after the acute phase of COVID-19. Achieving sustainable use of the ocean is one of the grand challenges of the new decade, and marine ecologists must play a more proactive role. (shrink)

Coronary arteries were studied on 110 postmortem human hearts during January 2000 to December 2001 in the department of Anatomy and Microbiology, Bangladesh Medical College to observed. The pattern of coronary dominance and its relation with atherosclerosis was observed. Atherosclerosis was found in 49(44.5%) samples, among which 37(56.%) were from male and 12(26.7%) from female hearts. This difference was significant (P<0.01). Right dominance was observed in 72 (65.5%) cases while 17 (15.5%) had left dominance and 21 (19.1%) had balanced (...) type of circulation. Balanced type of circulation was observed more among females (14; 66.7%) while left dominance was more frequent among males (13; 76.5 %). This deference on the basis of sex was significant (P<0.05). Significant (P<0.001) relationship was also observed between atherosclerosis and dominance of coronary artery. It may be concluded that atherosclerosis was present in almost half of the studied subjects and was found more among males. Left dominance was more frequently present among males it was associated with atherosclerosis. (shrink)

Due to the tremendous progress in technology and the methods used in its application to facilitate and refine human's life, Intelligent Tutoring System was created to contribute in this era. In this study, the Intelligent Tutoring System was adopted as a platform in linking the complex Technological fields for obtaining information smoothly, and highlighting the importance of water issues and in the Gaza strip. In the light of the absence and inability of the formal education system to raise awareness (...) of the water crisis and its consequences on the daily life of the Gazans, the current Intelligent Tutoring System (ITS) has been utilized to disseminate knowledge and enhance awareness of water problems. The ITS aims to embrace a new water conservation practices and ensure the sustainability of fresh water. Basically the software of the tutoring system is used to create a program which could be easily used by the public population and specialists in the water field. The resulting program was fed with plenty of information about the current local water status and its related problems which are considerably useful for anyone interested to raise his/her level of knowledge and awareness about the local water status in addition to the researchers by reducing their dependency on human sources. The ITS system was presented to two groups of people: The first one consists of specialized water experts and the other consists of master student enrolled in Institute of Water and Environment in Al-Azhar University in Gaza who are interested in water problems. Both groups were requested to use the final version of the system and give their feedback by filling a questionnaire, and then the averages of the answered questions were measured for each group. It was found that the overall impressions of the users were positive. (shrink)

The hippocampus is known to be comprised of several subfields, but the developmental trajectories of these subfields are under debate. In this study, we analyzed magnetic resonance imaging data from a cross-sectional sample using an automated segmentation tool to delineate the development of the hippocampal subregions from 6 to 26 years of age. We also examined whether gender and hemispheric differences influence the development of these subregions. For the whole hippocampus, the trajectory of development was observed to be an inverse-u. (...) A significant increase in volume with age was found for most of the subregions, except for the L/R-parasubiculum, L/R-fimbria, and L-HATA. Gender-related differences were also found in the development of most subregions, especially for the hippocampal tail, CA1, molecular layer HP, GC-DG, CA3, and CA4, which showed a consistent increase in females and an early increase followed by a decrease in males. A comparison of the average volumes showed that the right whole hippocampus was significantly larger, along with the R-presubiculum, R-hippocampal-fissure, L/R-CA1, and L/R-molecular layer HP in males in comparison to females. Additionally, the average volume of the right hemisphere was shown to be significantly larger for the hippocampal tail, CA1, molecular layer HP, GC-DG, CA3, and CA4. However, for the presubiculum, parasubiculum, and fimbria, the left side was shown to be larger. In conclusion, the hippocampal subregions appear to develop in various ways from childhood to adulthood, with both gender and hemispheric differences affecting their development. (shrink)

While cochlear implantation has benefitted many patients with single-sided deafness (SSD), there is great variability in cochlear implant (CI) outcomes and binaural performance remains poorer than that of normal-hearing (NH) listeners. Differences in sound quality across ears – temporal fine structure (TFS) information with acoustic hearing versus coarse spectro-temporal envelope information with electric hearing – may limit integration of acoustic and electric patterns. Binaural performance may also be limited by inter-aural mismatch between the acoustic input frequency and the place of (...) stimulation in the cochlea. SSD CI patients must learn to accommodate these differences between acoustic and electric stimulation to maximize binaural performance. It is possible that training may increase and/or accelerate accommodation and further improve binaural performance. In this study, we evaluated lateralization training in NH subjects listening to broad simulations of SSD CI signal processing. A 16-channel vocoder was used to simulate the coarse spectro-temporal cues available with electric hearing; the degree of inter-aural mismatch was varied by adjusting the simulated insertion depth (SID) to be 25 mm (SID25), 22 mm (SID22), and 19 mm (SID19) from the base of the cochlea. Lateralization was measured using headphones and head-related transfer functions (HRTFs). Baseline lateralization was measured for unprocessed speech (UN) delivered to the left ear to simulate SSD and for binaural performance with the acoustic ear combined with the 16-channel vocoders (UN+SID25, UN+SID22, and UN+SID19). After completing baseline measurements, subjects completed 6 lateralization training exercises with the UN+SID22 condition, after which performance was re-measured for all baseline conditions. Post-training performance was significantly better than baseline for all conditions (p<0.05 in all cases), with no significant difference in training benefits among conditions. Given that there was no significant difference between the SSD and the SSD CI conditions before or after training, the results suggest that NH listeners were unable to integrate TFS and coarse spectro-temporal cues across ears for lateralization, and that inter-aural mismatch played a secondary role at best. While lateralization training may benefit SSD CI patients, the training may largely improve spectral analysis with the acoustic ear alone, rather than improve integration of acoustic and electric hearing.

The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing environment to four other instructional methods—one‐on‐one human tutoring, observing tutoring individually, collaborating without observing, and studying alone—the results showed that students learned to solve physics problems just (...) as effectively from observing tutoring collaboratively as the tutees who were being tutored individually. We explain the effectiveness of this learning environment by postulating that such a situation encourages learners to become active and constructive observers through interactions with a peer. In essence, collaboratively observing combines the benefit of tutoring with the benefit of collaborating. The learning outcomes of the tutees and the collaborative observers, along with the tutoring dialogues, were used to further evaluate three hypotheses explaining why human tutoring is an effective learning method. Detailed analyses of the protocols at several grain sizes suggest that tutoring is effective when tutees are independently or jointly constructing knowledge: with the tutor, but not when the tutor independently conveys knowledge.

Both the Sarbanes–Oxley Act of 2002 and the Dodd-Frank Act of 2010 include clawback provisions that require executives to pay back incentive compensation earned on financial statements that are restated in a subsequent period. Such provisions intend to reduce unethical reporting behavior by executives who otherwise might be more inclined to misstate financial statements to boost incentive-based compensation. However, such provisions could promote rather than deter unethical behavior. In particular, Pyzoha :2515–2536, 2015) finds that, under certain conditions, executives are less (...) willing to restate financial statements in the presence of a clawback policy. Similarly, auditors might also act unethically by being less likely to propose restatements in the presence of clawbacks to avoid upsetting management. To examine this possibility, this study reports the results of three experiments that examine the effect of clawback provisions on auditor judgment. Contrary to expectations, our three experiments, along with supplemental qualitative evidence consistently indicate that clawbacks do not affect auditors’ propensity to propose restatements. These results suggest that a decrease in the number of restatements in a clawback environment will not be due to auditors acting unethically to appease management. The effects of clawbacks on auditors’ risk assessments, however, are less conclusive. As such, we offer potential post hoc explanations to guide future research. (shrink)

This paper studies how the human capital embedded in rank-and-file employees affects firms’ stock price crash risk. Employing a unique setting in China where we measure human capital using employee information at the firm level, we show that human capital quality improves firms’ internal information environments, curbs bad-news hoarding and overinvestment, leading to lower stock price crash risk. The findings are robust to instrumental variable regressions. Our study highlights the internal informational role of human capital and (...) sheds light on its implications for capital markets and outside investors. Therefore, we contribute to the literature on the interaction between non-shareholding stakeholders and shareholders. (shrink)

Learning is a central component of human life and essential for personal development. Therefore, utilizing new technologies in the learning context and exploring their combined potential are considered essential to support self-directed learning in a digital age. A learning environment can be expanded by various technical and content-related aspects. Gamification in the form of elements from video games offers a potential concept to support the learning process. This can be supplemented by technology-supported learning. While the use of tablets (...) is already widespread in the learning context, the integration of a social robot can provide new perspectives on the learning process. However, simply adding new technologies such as social robots or gamification to existing systems may not automatically result in a better learning environment. In the present study, game elements as well as a social robot were integrated separately and conjointly into a learning environment for basic Spanish skills, with a follow-up on retained knowledge. This allowed us to investigate the respective and combined effects of both expansions on motivation, engagement and learning effect. This approach should provide insights into the integration of both additions in an adult learning context. We found that the additions of game elements and the robot did not significantly improve learning, engagement or motivation. Based on these results and a literature review, we outline relevant factors for meaningful integration of gamification and social robots in learning environments in adult learning. (shrink)

Members of organizations are continually making decisions that have important consequences for themselves and the firms for which they work. In some cases these decisions affect human well being and social welfare and thus have important ethical impacts for those affected by the decisions.This study examines if certain strategic situations (enhancement of firm profits versus personal economic well being) cause decision makers to act more or less ethically. A questionnaire consisting of two vignettes which depicted actual business situations was (...) used to collect data from 171 managers of a large Southeastern financial and communication conglomerate. Results from multivariate repeated measures tests suggest that managers will vary their level of ethical response when faced with a situation where their own economic well being is at stake.

Motion pose capture technology can effectively solve the problem of difficulty in defining character motion in the process of 3D animation production and greatly reduce the workload of character motion control, thereby improving the efficiency of animation development and the fidelity of character motion. Motion gesture capture technology is widely used in virtual reality systems, virtual training grounds, and real-time tracking of the motion trajectories of general objects. This paper proposes an attitude estimation algorithm adapted to be embedded. The previous (...) centralized Kalman filter is divided into two-step Kalman filtering. According to the different characteristics of the sensors, they are processed separately to isolate the cross-influence between sensors. An adaptive adjustment method based on fuzzy logic is proposed. The acceleration, angular velocity, and geomagnetic field strength of the environment are used as the input of fuzzy logic to judge the motion state of the carrier and then adjust the covariance matrix of the filter. The adaptive adjustment of the sensor is converted to the recognition of the motion state. For the study of human motion posture capture, this paper designs a verification experiment based on the existing robotic arm in the laboratory. The experiment shows that the studied motion posture capture method has better performance. The human body motion gesture is designed for capturing experiments, and the capture results show that the obtained pose angle information can better restore the human body motion. A visual model of human motion posture capture was established, and after comparing and analyzing with the real situation, it was found that the simulation approach reproduced the motion process of human motion well. For the research of human motion recognition, this paper designs a two-classification model and human daily behaviors for experiments. Experiments show that the accuracy of the two-category human motion gesture capture and recognition has achieved good results. The experimental effect of SVC on the recognition of two classifications is excellent. In the case of using all optimization algorithms, the accuracy rate is higher than 90%, and the final recognition accuracy rate is also higher than 90%. In terms of recognition time, the time required for human motion gesture capture and recognition is less than 2 s. (shrink)
