On their journeys toward senior athletic status, junior endurance athletes are faced with a multitude of stressors. How athletes react to stressors plays a vital part in effective adaptation to the demanding, ever-changing athletic environment. Sleep, the most valued recovery strategy available to athletes, has the potential to influence and balance athletic stress, and enable optimal functioning. However, sleep is sensitive to disturbances by stress, which is described by the concept of sleep reactivity. Among athletes, poor sleep quality is frequently (...) reported, but our understanding of the associations between stress and sleep in junior athletes is currently incomplete. The present study therefore investigated the themes of stress and sleep, and the associations between these variables with the use of in-depth semi-structured interviews in six junior endurance athletes. Data was analyzed qualitatively based on the Grounded Theory. The qualitative material was supplemented with quantitative data on subjective sleep quality, sleep reactivity, and mental strain. The main results showed that stress could be differentiated into relevant stressors and reactions to stress. Sleep could be differentiated into sleep benefits and sleep quality. All athletes identified relevant stressors, and all athletes were aware of the benefits of sleep for athletic functioning. However, athletes formed two distinctive categories based on the interactions between stress and sleep: three exhibited facilitative reactions to stress and good sleep quality, as well as low sleep reactivity, and low mental strain. The remaining participants exhibited maladaptive reactions to stress and poor sleep quality, as well as high sleep reactivity and high mental strain. Conceptualizing sleep quality based on the evaluation of stressors, reactions to stress, degree of mental strain, and the propensity to stress-related sleep disturbance may offer a plausible explanation for why the occurrence of stressors leads to poor sleep quality in some athletes, but not others.

ObjectiveThis article explores the effect of preoperative health education, in the form of animation videos, on postoperative self-reported pain levels and anxiety in femoral fractures.MethodsNinety cases of femoral fracture were divided at random into the oral instruction group, the recorded video group, and the animation video group, with 30 cases in each group. Sociodemographic data were collected the day before surgery. Health education was then offered in one of three ways: orally, using a recorded video, or using an animation (...) video. On days 2, 4, and 7 after surgery, the state-trait anxiety inventory and the visual analog scale were used to assess postoperative anxiety and pain levels, respectively, in the participants.ResultsAt different time points during the evaluation, total anxiety scores in the animation and recorded video groups were significantly lower than in the oral instruction group. STAI scores in the three groups were found to have significant interactions with the measurement time in the three groups.ConclusionPreoperative health education with the aid of multimedia is more effective than oral instruction in lowering patients’ postoperative anxiety and pain levels. In addition, animation videos are superior to recorded videos in mitigating postoperative anxiety. Whether the two approaches differ in reducing postoperative pain in bone fractures remains to be further tested. (shrink)

Creativity is so important for social and technological development that people are eager to find an easy way to enhance it. Previous studies have shown that mindfulness has significant effects on positive affect, working memory capacity, cognitive flexibility and many other aspects, which are the key to promoting creativity. However, there are few studies on the relationship between mindfulness and creativity. The mechanism between mindfulness and creativity is still uncertain. Meditation is an important method of mindfulness training, but for most (...) people who do not have the basic training, it’s difficult to master how to get into a state of mindfulness. Animation has been shown by many studies to help improve cognition and is often used as a guiding tool. Using animation as the guiding carrier of meditation is more convenient and easier to accept. Therefore, this study adopted the intervention method of animation-guided meditation, aiming to explore: the effect of animation-guided meditation on enhancing creativity; the role of flow and emotion in the influence of mindfulness on creativity. We advertised recruitment through the internal network of a creative industrial park, and the final 95 eligible participants were divided into two groups: animation and audio guided meditation. The animation group was given an animated meditation intervention, and the audio group was given an audio meditation intervention, both interventions were performed 3 times a week and last for 8 weeks. Results: Animation-guided meditation significantly increased participants’ mindfulness and creativity levels; Significantly reduced their cognitive load compared to audio-guided meditation. Mindfulness has a significant direct effect on creativity, and significant indirect effects on creativity; Flow and PA act as the mediating variable. Conclusion: Mindfulness, flow, and PA all helped to improve the subjects’ work creativity. In addition to the direct positive impact of mindfulness on creativity, mindfulness can also have an indirect positive impact on creativity through flow and PA. Compared with audio, animation can significantly reduce cognitive load and help improve users’ cognitive ability, which is more suitable for the guidance materials of mindfulness meditation to enhance the effect of meditation.

There is controversy around whether presenting sub-character units such as radicals and strokes are beneficial to L2 Chinese learning. The present study explored the effects of radical markings and stroke order animations on learning Chinese characters. Forty Chinese L2 learners with native alphabetic languages were divided into high-and low-level groups. They were first required to learn Chinese characters under four conditions either: presented radical markings with stroke animations; presented no radical markings with stroke animations; presented radical markings without stroke animations; (...) or presented neither radical markings nor stroke animations. After learning, the participants were given character recognition and character-meaning matching tests. Results showed that the presentation of radical markings increased the participants’ reaction times in the character recognition test and decreased their recognition accuracy. Moreover, presenting stroke order animations also decreased the participants’ accuracy in recognizing characters. Beyond that, presenting radical markings and stroke order animations had no significant influence on character-meaning matching tests. These results indicate that providing radical and stroke information might interfere with character learning instead of facilitating character learning. The results suggest that excessive visual information introduced in the learning process may increase L2 learners’ cognition load. Also, the findings contribute to theoretical arguments about the analytic and holistic processing of Chinese characters and the pedagogical implications for teaching Chinese as a second language.

Retinoids are low molecular weight, lipophilic derivatives of vitamin A which have a profound effect upon the development of a diverse array of animals. Here, I review these effects on Invertebrates: a colonial hydroid, a colonial ascidian, and Vertebrates: the regenerating amphibian limb, the developing chick limb bud, the regenerating amphibian tail, the anteroposterior axis of the early embryo, the developing chick embryo skin. There is a striking uniformity of effect of retinoids on pattern formation when applied (...) to these diverse organisms. The majority react by being posteriorized in their development, although additional effects can also be seen. Several hypotheses which can explain these results are discussed along with the deduction that they lead to: retinoids may be components of a universal developmental mechanism or they may simply act in a similar way to alter a universal developmental mechanism. In either case the experimental analysis of retinoid effects on development has important implications for the evolution of developmental mechanisms. (shrink)

Loving-kindness meditation was first practiced by Buddhists and then developed by clinical psychologist. Previous studies on LKM have mainly focused on the impact of real person-guided meditation on depression, anxiety, and other negative psychology. During the COVID-19 pandemic, this study explored the effect and mechanism of media-guided LKM on the improvement of social presence, mindfulness, spirituality, and subjective wellbeing. From the viewpoint of positive psychology, this study compared the different media effects of animated pedagogical agent -guided LKM and audio-guided (...) LKM. A total of 82 flight attendants were recruited from airlines; then, they were randomly assigned to two groups: APA group and audio group, which both underwent an 8-week LKM training intervention. The aforementioned four main variables were measured pre and post the meditation experiment. The results indicated that both APA-guided meditation and audio-guided meditation significantly improved subjects’ spirituality and SWB. Compared with audio-guided meditation, APA-guided meditation significantly improved the subjects’ spirituality, SWB, and social presence. Audio-guided meditation has no significant effect on social presence. This study highlights APA-guided meditation has a positive effect on spirituality, SWB, and social presence, which may provide individuals with a simple and easy method to improve their mental health.

The effects of handling on the exploratory activity of rats in settings varying in level of sensory stimulation1 This study tests the assumptions of need for stimulation theory. According the main hypothesis of this theory, the stimulus seeking activity of an organism in an unfamiliar environment is affected by two main temperamental traits: emotional reactivity and need for stimulation. In a familiar setting, the influence of emotional reactivity disappears, while the need for stimulation persists. Two experiments were run in which (...) animals' emotionality was manipulated by means of presence or absence of handling and the level of environmental stimulation was manipulated by varying the intensity of light to which the animals were exposed. Sixty male Wistar rats were tested in the first experiment. Stimulus seeking activity was registered in the Skinner-type chambers where animals could switch the light on by every head dip into one of two holes, the so-called experimental hole. Animals were tested in five 30-minute sessions repeated every 48 hours. As predicted, the effect of emotionality on exploration emerged at the beginning of the experiment, whereas the effect of the level of environmental stimulation on the total number of head-dips emerged in all the experimental sessions. The second experiment involved 40 rats and followed a similar design, but the stimulus seeking activity was measured in the situation where the animals could switch the light off by dipping their heads into the experimental hole. Contrary to predictions, the experimental factors had no significant effect on the animals' stimulus seeking activity. Only the results of the first experiment confirm the assumptions of need for stimulation theory. (shrink)

The potential anesthetic neurotoxicity on the neonate is an important focus of research investigation in the field of pediatric anesthesiology. It is essential to understand how these anesthetics may affect the development and growth of neonatal immature and vulnerable brains. Functional magnetic resonance imaging has suggested that using anesthetics result in reduced functional connectivity may consider as core sequence for the neurotoxicity and neurodegenerative changes in the developed brain. Anesthetics either directly impact the primary structures and functions of the brain (...) or indirectly alter the hemodynamic parameters that contribute to cerebral blood flow in neonatal patients. We hypothesis that anesthetic agents may either decrease the brain functional connectivity in neonatal patients or animals, which was observed by fMRI. This review will summarize the effect and mechanism of anesthesia on the rapid growth and development infant and neonate brain with fMRI through functional connectivity. It is possible to provide the new mechanism of neuronal injury induced by anesthetics and objective imaging evidence in animal developing brain. (shrink)

ABSTRACTWe investigated the impact of emotions on learning vocabulary in an unfamiliar language to better understand affective influences in foreign language acquisition. Seventy native English speakers learned new vocabulary in either a negative or a neutral emotional state. Participants also completed two sets of working memory tasks to examine the potential mediating role of working memory. Results revealed that participants exposed to negative stimuli exhibited difficulty in retrieving and correctly pairing English words with Indonesian words, as reflected in a lower (...) performance on the prompted recall tests and the free recall measure. Emotional induction did not change working memory scores from pre to post manipulation. This suggests working memory could not explain the reduced vocabulary learning in the negative group. We argue that negative mood can adversely affect language learning by suppressing aspects of native-language processing and impeding form-meaning mapping with second language words. (shrink)

Should you help a wild rabbit fleeing a wall of flame? What is our responsibility to wildlife affected by wildfire? This paper focuses on two cases of ad hoc public aid to wildlife that occurred during California's 2017 'Thomas Fire' and were subsequently popularised online. We take the discourse surrounding these cases - specifically, a viral video of a man removing a wild rabbit from the fire's flames and the widespread call to leave out buckets of water for displaced (...) class='Hi'>animals - as an invitation to engage in broader ethical and theoretical discussion about our individual relationships to wild animals during the age of ecological crisis termed the Anthropocene. Through this case analysis, we identify emerging tensions between what we call 'interventionist' and 'anti-interventionist' positions and assert that, while anti-interventionist positions are generally framed in rational, empirical or technocratic terms, a full consideration of already-existing human entanglements with the natural world troubles this frame. We conclude that the Anthropocene presents unique circumstances that give substantial support to the interventionist position; at the same time, we continue to uphold the value of key critiques present in the anti-interventionist argument, which might yet help to shape the most effective form of human aid to wild animals and alleviate problems of ecological sustainability, more broadly.

Outcomes of interspecific competition, and especially the possibility of coexistence, have been extensively studied in theoretical ecology because of their implications in community assemblages. During the last decades, the influence of different time scales through the local/regional dynamics of animal communities has received an increasing attention. Nevertheless, different time scales involved in interspecific competition can result form other processes than spatial dynamics. Here, we envision and analyze a new theoretical framework that couples a game theory approach for competition with a (...) demographic model. We take advantage of these two time scales to derive a reduced model governing the total densities of the two populations and we study how these two time scales interfere and influence outcomes of species competition. We find that a competition process occurring on a faster time scale than demography yields a “priority effect” where the first species introduced outcompetes the other one. We then confirm previous findings stipulating that species coexistence is favored by large difference in time scales because the extinction/recolonization process. Our results then highlight that an integration of demographic and competition time scales at both local and regional levels is mandatory to explain communities assemblages and should become a research priority.

Many prominent critiques of philosophical methods proceed by suggesting that some method is unreliable, especially in comparison to some alternative method. In light of this, it may seem natural to conclude that these (comparatively) unreliable methods should be abandoned. Drawing upon work on the division of cognitive labour in science, we argue things are not so straightforward. Rather, whether an unreliable method should be abandoned depends heavily on the crucial question of how we should divide philosophers’ time and effort between (...) different methods, in order to maximise our prospects of achieving epistemic success. We show that, in a range of cases, even a (comparatively) unreliable method deserves to be allocated some of these resources. (shrink)

Arginine vasopressin (AVP) is a powerful regulator of various social behaviors across many species. However, seemingly contradictory effects of AVP have been found in both animal and human studies, e.g., promoting aggression on one hand and facilitating social bonding on the other hand. Therefore, we hypothesize that the role of AVP in social behaviors is context-dependent. To this end, we examined the modulatory effect of AVP on male’s behavioral and neural responses to infant and adult cues. After intranasal and (...) double-blind treatment of AVP or placebo, male participants were asked to rate their subjective approaching willingness to infant and adult faces in specific contexts informed by cue words while EEG recording. Our results showed that AVP treatment increased approaching ratings to neutral and positive other-gender adult faces compared to emotional matched same-gender adult faces, and to negative girl faces compared to negative boy faces. Furthermore, compared to placebo treatment, AVP treatment induced larger N1 amplitudes to neutral cues associated with both adults and infants, whereas AVP treatment only sustained pronounced late positive potential (LPP) amplitudes to neutral cues of infants but not adults. Those findings implicate differential roles of AVP in the processing of adult- and infant-related cues and thus lend support to the context-dependent account. (shrink)

Previous studies have shown that the color red can affect basic motor functioning. However, these studies utilized simple gross motor tasks rather than those assessing complex fine motor skills. Moreover, these empirical studies were theoretically based on the threat–behavior link in human and non-human animals, and neglected the relationship between arousal and motor performance. According to the Yerkes–Dodson law and the inverted-U hypothesis in sport psychology, for simple motor tasks, high arousal is more advantageous than low arousal ; for (...) complex motor tasks, low arousal is more advantageous than high arousal. The current research examined the effect of color on different kinds of motor skills based on the inverted U-hypothesis. In Experiment 1, we examined the effect of red and blue on dart-throwing performance, whereas in Experiment 2, we examined the effect of red and blue on grip strength performance. The results showed that performance of fine motor skill in the blue condition was better than in the red condition, and performance of gross motor skill in the red context was better than in the blue context. These results indicate that the type of motor skill assessed moderates the influence of red and blue on motor performance. (shrink)

With the innovation of computer, virtual clothing has also emerged. This research mainly discusses the real-time animation complex of interactive clothing design based on computer simulation. In the process of realizing virtual clothing, the sample interpolation synthesis method is used, and the human body sample library is constructed using the above two methods first, and then, the human body model is obtained by interpolation calculation according to the personalized parameters. Building a clothing model is particularly important for the effect (...) of trying on. The clothing that needs to be displayed can be scanned and then input into the computer to build the model. The model can be directly built in 3DMAX and other software and then its surface texture can be mapped, or the clothing model can be directly built. The 3D model in the 3ds file is loaded by the loop body nested switch branch selection structure. Correspondingly, the write-back operation of 3ds files is similar. Just follow the general structure of the 3ds file and write the root block, version information block, edit information block, key frame information block, etc. to a brand new file in sequence. The main reason for this article to perform the 3ds file write-back operation is that, after the clothing model is dynamically simulated through the dynamic principle, the deformed key animation frame needs to be saved as a 3ds file so that it can be further imported into the 3DSMAX software and generated by the renderer, form high-quality picture information, and finally get high-definition animation video. In the CPU-GPU hybrid method, modules such as force calculation, collision processing, and position update use the GPU method, while overstretching is processed by the CPU method, making the overall performance 10 times higher than the pure CPU method. This research helps to promote the development of 3D virtual clothing design. (shrink)

A well‐known typological observation is the dominance of subject‐initial word orders, SOV and SVO, across the world's languages. Recent findings from gestural language creation paradigms offer possible explanations for the prevalence of SOV. When asked to gesture transitive events with an animate agent and inanimate patient, gesturers tend to produce SOV order, regardless of their native language biases. Interestingly, when the patient is animate, gesturers shift away from SOV to use of other orders, like SVO and OSV. Two competing hypotheses (...) have been proposed for this switch: the noisy channel account (Gibson et al., 2013) and the role conflict account (Hall, Mayberry, & Ferreira, 2013). We set out to distinguish between these two hypotheses, disentangling event reversibility and patient animacy, by looking at gestural sequences for events with two inanimate participants (inanimate‐inanimate, reversible). We replicated the previous findings of a preference for SOV order when describing animate‐inanimate, irreversible events as well as a decrease in the use of SOV when presented with animate‐animate, reversible events. Accompanying the drop in SOV, in a novel condition we observed an increase in the use of SVO and OSV orders when describing events involving two animate entities. In sum, we find that the observed avoidance of SOV order in gestural language creation paradigms when the event includes an animate agent and patient is driven by the animacy of the participants rather than the reversibility of the event. We suggest that findings from gestural creation paradigms are not automatically linkable to spoken language typology. (shrink)

Two eye-tracking experiments investigated how and when pointing gestures and location descriptions affect target identification. The experiments investigated the effect of gestures and referring expressions on the time course of fixations to the target, using videos of human gestures and human voice, and animated gestures and synthesized speech. Ambiguous, yet informative pointing gestures elicited attention and facilitated target identification, akin to verbal location descriptions. Moreover, target identification was superior when both pointing gestures and verbal location descriptions were used. These (...) findings suggest that gesture not only operates as a context to verbal descriptions, or that verbal descriptions operate as a context to gesture, but that they complement one another in reference resolution.

Previous studies have shown that viewing cute pictures leads to performance improvement in a subsequent fine motor task. We examined the beneficial effects of viewing cute pictures in a more complex sporting skill by comparing three conditions and two tests. The participants, all of whom were college basketball players, performed 16 free throws in each condition. In the no-pressure test, male participants improved performance after viewing pictures of baby animals but not after adult animals and no pictures. In (...) the pressure test, no significant improvement was observed. For female participants, the cuteness-viewing effect was not observed in both tests. The results suggest that viewing cute pictures may improve performance during basketball free throws in a low-pressure situation by narrowing the breadth of attentional focus and inducing approach motivation and caregiving behaviors.

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck or the withers for three consecutive weeks, the third group was exposed to close visual presence. After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in stepping during rectal palpation, which occurred less often in Neck- and (...) Withers-animals than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation.

Workers can be fired from jobs, citizens sent to jail, and adolescents more likely to experience depression, all because of algorithms. Algorithms have considerable impacts on our lives. To increase user satisfaction and trust, the most common proposal from academics and developers is to increase the transparency of algorithmic design. While there is a large body of literature on algorithmic transparency, the impact of unethical data collection practices is less well understood. Currently, there is limited research on the factors that (...) affect users’ trust in data collection practices and algorithmic transparency. In this research, we explore the relative impact of both factors as they relate to important outcome measures such as user’s trust, comfort level, and moral acceptability. We conducted two pilot studies to learn what real users consider to be ethical and unethical data collection practices, as well as high and low transparency for algorithms. We then used these findings in a 2 × 2 design to examine how transparency and the acceptability of data collection practices impact users’ acceptance, comfort, and trust in algorithms. Our results suggest that the singular emphasis on algorithmic transparency may be misplaced. Given the difference in their impact to increase acceptance, trust, and user satisfaction, a more effective strategy would be to also understand and abide by users’ views of ethical data collection practices.

Across species, animals have an intrinsic drive to approach appetitive stimuli and to withdraw from aversive stimuli. In affective science, influential theories of emotion link positive affect with strengthened behavioural approach and negative affect with avoidance. Based on these theories, we predicted that individuals’ positive and negative affect levels should particularly influence their behaviour when innate Pavlovian approach/avoidance tendencies conflict with learned instrumental behaviours. Here, across two experiments – exploratory Experiment 1 (N = 91) and a preregistered confirmatory Experiment (...) 2 (N = 335) – we assessed how induced positive and negative affect influenced Pavlovian-instrumental interactions in a reward/punishment Go/No-Go task. Contrary to our hypotheses, we found no evidence for a main effect of positive/negative affect on either approach/avoidance behaviour or Pavlovian-instrumental interactions. However, we did find evidence that the effects of induced affect on behaviour were moderated by individual differences in self-reported behavioural inhibition and gender. Exploratory computational modelling analyses explained these demographic moderating effects as arising from positive correlations between demographic factors and individual differences in the strength of Pavlovian-instrumental interactions. These findings serve to sharpen our understanding of the effects of positive and negative affect on instrumental behaviour. (shrink)

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.

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)

One hundred and eleven participants interacted with one of four entities: an AIBO robotic dog, Legobot, Dog or Cat.

However, participants were not positively biased toward live entities, as (...) the Cat often was thought of and spoken to similarly to the AIBO robot. Results are consistent with a model in which both appearance and interactivity lead to the development of beliefs about a live or robotic entity in an interaction.

We study the influence of the individual behaviour of animals on predator-prey models. Populations of preys and predators are divided into sub-populations corresponding to different activity classes. The animals are assumed to do many activities all day long such as searching for food of different types. The preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study activity sequences of the (...) animals and also the effect of a change in the average individual behaviour of the animals on Lotka-Volterra prey-predator interactions. Numerical simulations are realized for the whole sets of equations (governing the subpopulations) and are compared to the simulations of the reduced sets of equation (governing the populations). We look for the validity of the method with respect to a scaling factor which measures the differences between the two time scales associated to the fast-varying variables and to the slow-time varying global variables. It is shown that when the two time scales differ of about two orders of magnitude, the approximation is satisfying. (shrink)

Results showed that more donations were given with the dog and (...) cat banks, whereas no difference in donations was found among the three other banks. (shrink)

Social movements have driven large shifts in public attitudes and values, from anti-slavery to marriage equality. A central component of these movements is moral persuasion. We conduct a randomized-controlled trial of pro-vegan animal-welfare pamphlets at a college campus. We observe the effect on meat consumption using an individual-level panel data set of approximately 200,000 meals. Our baseline regression results, spanning two academic years, indicate that the pamphlet had no statistically significant long-term aggregate effects. However, as we disaggregate by gender (...) and time, we find small statistically significant effects within the semester of the intervention: a 2.4 percentage-point reduction in poultry and fish for men and a 1.6 percentage-point reduction in beef for women. The effects disappear after 2 months. We merge food purchase data with survey responses to examine mechanisms. Those participants who self-identified as vegetarian, reported thinking more about the treatment of animals or expressed a willingness to make big lifestyle changes reduced meat consumption during the semester of the intervention. Though we find significant effects on some subsamples in the short term, we can reject all but small treatment effects in the aggregate. (shrink)

A general framework for analysing the effects of variability and the effects of interruptions on foraging is presented. The animal is characterised by its level of energetic reserves, x. We consider behaviour over a period of time [0,T]. A terminal reward function R(x) determines the expected future reproductive success of an animal with reserves x at time T. For any state x at a time in the period, we give the animal a choice between various options and then constrain it (...) to follow a background strategy. The best option is the one that maximizes expected future reproductive success. Using this framework, we show that sensitivity to variability in amount of energy gained is logically distinct from sensitivity to variability in the time at which food is obtained. We also show that incorporating interruptions results in both a preference for variability in time and a preference for a reward followed by a delay as opposed to the same delay before the reward.

American undergraduates rated masculinity, femininity, and likability of two men from a videotaped interaction. Participants were informed that both men were cat persons, dog persons, heterosexual, adopted, or gay, or were unlabeled. Participants rated the men less masculine when cat persons than when dog persons or unlabeled, and less masculine and more feminine when gay than when anything else or unlabeled. The more masculine man received lower feminine ratings when a dog person than when a heterosexual, and higher masculine ratings (...) when a dog person than when unlabeled. Labels did not affect likability. Overall, the gay label consistently promoted cross-gender attributions, the dog person label encouraged somewhat heightened gender-appropriate attributions, and the cat person label allowed for normative attributions.

Two experiments are described that investigate the effects of attention in moderating evaluative conditioning (EC) effects in a picture‐picture paradigm in which previously discovered experimental artifacts (e.g., Field & Davey, 1999 Field, AP, and Davey, GCL, (1999). Reevaluating evaluative conditioning: A nonassociative explanation of conditioning effects in the visual evaluative conditioning paradigm, Journal of Experimental Psychology. Animal Behavior Processes 25 ((1999)), pp. 211–224.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) were overcome by counterbalancing conditioned stimuli (CSs) and unconditioned stimuli (USs) (...) across participants. Conditioned responses for individuals who had attention enhanced were compared against a control group and groups for whom attention was impeded using a distracter task. In a second experiment the effects of attention were dissociated from those of contingency awareness by using backward‐masked US presentations. The results of these experiments indicate that although associative EC effects may not be disrupted by a lack of contingency awareness, attention is an important factor in establishing conditioning. These results shed some light onto the possible boundary conditions that could explain past inconsistencies in obtaining EC effects in the visual paradigm. (shrink)

PurposeThe aim of this study was to investigate the differential effects of Tai Chi vs. brisk walking on cognitive function among individuals aged 60 and greater.Patients and MethodsFor participant recruitment, a health talk was arranged at two communities in which two different exercise modalities were assigned to participants of each community free of charge. The intervention programs lasted 10 weeks, with three 60-min training sessions per week. General cognitive ability and specific cognitive outcomes were measured using the Chinese version of (...) the Montreal Cognitive Assessment.ResultsA significant interaction on total scores of the MoCA was observed. Post hoc analysis indicated significant improvements on general cognitive performance as measured in performance on the MoCA for both exercise groups at the end of 10 weeks. A significant interaction was only observed on the delayed recall sub-domain. Results from post hoc analysis indicate that the Tai Chi group had a significantly better memory performance relative to brisk walking group. Specifically, significant improvement was observed in Tai Chi group, but not in the brisk walking group. Both exercise groups demonstrated significant improvements from baseline to Week 10, which emerged in visualspatial ability and attention performance. Lastly, animal naming and orientation significantly benefited from brisk walking and Tai Chi training, respectively.ConclusionTai Chi and brisk walking as the most commonly used, culture-specific mind-body exercise method have been proven to be effective in improving general cognitive performance and specific cognitive domains. Furthermore, differential effects of two different exercise modalities on cognitive domains were observed, which has provided insightful information for customized exercise programs. Finally, aging individuals who are experiencing cognitive decline should either take Tai Chi classes regularly or engage in brisk walking, which could contribute to brain health. (shrink)

"We face three epoch-defining environmental problems: climate, extinction and pestilence. Our climate is changing in ways that will have serious consequences for humans, and may even profoundly affect the ability of the planet to support life. All around us, other species are disappearing at a rate between several hundred and several thousand times the normal background rate of extinction. The SARS-CoV-2 virus, which has wreaked social and economic havoc, is merely the latest model off a blossoming production line of newly (...) emerging infectious diseases, many of which have the potential to be far worse. At the heart of these problems lies an ancient habit: eating animals. This habit is the most significant driver of species extinction and of newly emerging infectious diseases, and one of the most important drivers of climate change. This is a habit we can no longer afford to indulge. Breaking it will substantially reduce climate emissions. It will stem our insatiable hunger for land that is at the heart of both the problems of extinction and pestilence. Most importantly, breaking this habit will make available vast areas of land suitable for afforestation: the return of forests to where they once grew. Afforestation will significantly mitigate all three problems. But only if we stop eating animals will we have enough land for this strategy to work"--. (shrink)

In Canada, all institutions that conduct publicly funded, animal-based research are expected to comply with the standards of the Canadian Council on Animal Care (CCAC). The CCAC promotes the use of animal alternatives, and uses the “3Rs” principles of Replacement, Reduction, and Refinement as a guiding ethical framework. To ensure these standards are strictly enforced, internal ethics committees at each institution are tasked with creating “Animal Use Protocol” (AUP) forms to be filled out by researchers and evaluated by the committees. (...) In this paper, we assess AUP forms from Canada’s top research universities to identify the extent to which they conform to, or advance, the 3Rs framework. Our results show various deficiencies that call into question the quality of information elicited by these forms. To remedy this, we recommend that the CCAC assume responsibility for creating a standardized 3Rs section to be used on all AUP forms. In addition, proposal forms and experimental results for all research at CCAC-certified institutions should be digitized and uploaded into a national database. We argue that this would offer higher quality information for researchers at the experimental design stage, while strengthening the CCAC’s mandate to be accountable to the Canadian public. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.1 (2002) 124-137 [Access article in PDF] Katz's Problematic Dualism and Its "Seismic" Effects on His Theory Wayne Ouderkirk There is much to admire in Eric Katz's Nature as Subject. 1 Many aspects of his theory strongly resonate with dominant themes in environmental ethics and with my own theoretical predilections. In addition, he applies his theory to several major environmental issues (ecological restoration and the (...) Amazon rainforest, to name two), simultaneously testing it against other views and tracing out its implications. Impressive, non-ivory tower philosophizing. The array of issues he covers is impressive too, from the place of animal rights in an environmental ethic to the relation between environmental destruction and genocide; from the tension between holism and the rights of individuals to intrinsic value; from anthropo- centrism to Judaism and the environment; from the history of environmental thought to the convergence hypothesis. And more.In light of this tremendous range and of my own attraction to such of his major themes as ecocentrism, it might seem unappreciative to criticize, [End Page 124] to dissent. But despite all the positives I find in Katz's writings, I also find faults there, faults which, when pressed, cause major fissures in the whole. The central, major problem is Katz's dualism; and I think it ultimately undoes his whole theory, since it is so intimately connected with the other parts. Within Katz's own essays, there are, I think, resources to begin a reconstruction; but as with any other such effort, the first task is to discard the parts that are no longer useable. Before doing so, however, I want to review some positive aspects of Katz's theory, lest I convey the mistaken impression that my initial praise for his work is mere courtesy. The Solid Geological Features To begin with the most general: Katz's concern for, commitment to the natural world is obvious to any reader. He suffuses every essay with a determination to seek out clear and cogent philosophical rationales for its protection. More important perhaps is his obvious personal connection to that world. His references to Fire Island's deer and beaches, for example, amply demonstrate what the rest of his writings imply: that his theoretical efforts are more than armchair musings about a current philosophical issue. Katz's efforts are both professional and passionate.On a more specifically philosophical level, I regard his anti-anthropocentrism as a significant strength. Though one can, of course, be an anthropocentrist and be an environmental philosopher—Bryan Norton (1984) and Eugene Hargrove (1989) come to mind—I think Katz's arguments showing that anthropocentric views can only offer contingent justifications for protecting the environment are cogent and valid (3-11). An important part of those arguments is Katz's demonstration that different theories in environmental philosophy do indeed result in different environmental policies. In other words, Katz offers a strong counterargument to Norton's convergence hypothesis (Norton 1991), the idea that, given environmentalists' shared commitment to the environment, the various philosophical theories offered in justification of that commitment will converge on similar policy recommendations (149 ff.). I agree with Katz's refutation of that hypothesis, and I offer my critique of his theory because I think that theory's faults will ultimately undermine sound policies.Another big asset of Katz's theory is his communitarianism, the idea that we are part of an ecological community, an ecosystem, to which we have moral obligations. Not surprisingly to anyone familiar with environmental ethics, the source of this idea is Aldo Leopold's Land Ethic (Leopold 1966), [End Page 125] which has been debated, analyzed, praised, and critiqued more than extensively in the literature. Katz pretends to no originality here; he simply adopts and vigorously defends an ecocentric ethic that counts the integrity, stability, and beauty of the system—including, not incidentally, abiotic components—as central criteria limiting human interference with nature. Unlike, for example, the total ecocentrism of J. Baird Callicott's (1980) early writing, however, Katz tempers his communitarianism with another dimension, qualifying his holistic... (shrink)

In our world today, afflicted by wars between States, by conflict between groups within States, and by the scourge of terrorism, civilians constitute the ‘vast majority of casualties in situations of armed conflict’ (UN Security Council, Resolution 1894, 2009). Civilian victims of documented and un-documented armed conflicts and their destructive consequences run in the millions. An overwhelming majority of the dead, injured, disabled are civilians and damages caused by armed conflicts primarily affect the civilian infrastructure and the basic resources of (...) subsistence of entire populations. Civilians today are in the line of fire not only as a side effect of war. Increasingly, they are becoming the prime and intentional targets of combatants and armed elements. ‘Political and military designs supersede basic respect for the dignity and rights of persons and communities’ (Migliore 2009) and civilians are becoming deliberate targets and means for achieving political or military gains. They are even being used as a human shield for armed advancement. The menace of civilian deaths in the line of fire is of utmost concern for all humanity, for all religions, and for Christianity. Among the foundational teachings on which the Catholic perspective to this important issue of placing civilians in the line of fire is based, we can identify three core beliefs: a) all human beings are equal in dignity and their life is sacred; b) the right and duty to defend the life and common good from unjust aggressors; c) the permanent validity of the moral law forbidding murder even in the context of armed conflicts. After considering these the paper studies some of the ways in which the Catholic Church responds to the situation of civilians caught in the line of fire. (shrink)

Online social networks have rapidly become a prominent and widely used service, offering a wealth of personal and sensitive information with significant security and privacy implications. Hence, OSNs are also an important—and popular—subject for research. To perform research based on real-life evidence, however, researchers may need to access OSN data, such as texts and files uploaded by users and connections among users. This raises significant ethical problems. Currently, there are no clear ethical guidelines, and researchers may end up performing ethically (...) questionable research, sometimes even when more ethical research alternatives exist. For example, several studies have employed “fake identities” to collect data from OSNs, but fake identities may be used for attacks and are considered a security issue. Is it legitimate to use fake identities for studying OSNs or for collecting OSN data for research? We present a taxonomy of the ethical challenges facing researchers of OSNs and compare different approaches. We demonstrate how ethical considerations have been taken into account in previous studies that used fake identities. In addition, several possible approaches are offered to reduce or avoid ethical misconducts. We hope this work will stimulate the development and use of ethical practices and methods in the research of online social networks. (shrink)
