Emotions are viewed as having evolved through their adaptive value in dealing with fundamental life-tasks. Each emotion has unique features: signal, physiology, and antecedent events. Each emotion also has characteristics in common with other emotions: rapid onset, short duration, unbidden occurrence, automatic appraisal, and coherence among responses. These shared and unique characteristics are the product of our evolution, and distinguish emotions from other affective phenomena.

Suppose a diner says, 'Can you pass the salt?' Although her utterance is literally a question (about the physical abilities of the addressee), most would take it as a request (that the addressee pass the salt). In such a case, the request is performed indirectly by way of directly asking a question. Accordingly this utterance is known as an indirect speech act. On the standard account of such speech acts, a single utterance constitutes two distinct speech acts. On this account (...) then, 'Can you pass the salt?' is both a question and a request. In a provocative essay, Rod Bertolet argues that there are no indirect speech acts. According to Bertolet, 'Can you pass the salt?' is only a question. It is a question that merely functions as a request (without also being one). In this paper we respond to Bertolet's skeptical argument. Appealing to Searle's theory of speech acts and to certain features of linguistic communication, we argue that, despite Bertolet's challenge, there is good reason to countenance indirect speech acts.

Space tourism is an emerging field where few people have direct experience. However, considering the potential in the near future, it is beneficial to better understand how related information influences people’s attitudes about this new form of tourism. Employing information-processing-based Bayesian Mindsponge Framework (BMF) analytics on a dataset of 361 respondents consuming content related to space tourism on Chinese social media, we found that induced happiness and impression are positively associated with willingness to try space tourism. Information authenticity positively moderates (...) these two associations. Our findings emphasize three aspects of information during the processes of reception and filtering: meaning, intensity, and trust. Since promotional materials for space tourism rely heavily on mental simulations rather than objective feedback, creative uses of digital technology are advantageous. However, precautions must be taken to prevent exploitation, such as false advertising, exaggeration, and emotional manipulation. (shrink)

I argue that james otten's attempt to revive the logical connection argument by maintaining that there is a weak logical connection between causes and effects is a failure. Claiming that the weak logical connection is only a relation between descriptions of events rather than between events themselves, I conclude that otten has repeated the same mistake of confusing properties of propositions with properties of events made by earlier advocates of the lca.

Emotions are discrete, automatic responses to universally shared, culture-specific and individual-specific events. The emotion terms, such as anger, fear, etcetera, denote a family of related states sharing at least 12 characteristics, which distinguish one emotion family from another, as well as from other affective states. These affective responses are preprogrammed and involuntary, but are also shaped by life experiences.

Extant literature suggests a positive correlation between social trust (also called generalized trust) and life satisfaction. However, the psychological pathways underlying this relationship can be complex. Using the Bayesian Mindsponge Framework (BMF), we examined the influence of social trust in a high-violence environment. Employing Bayesian analysis on a sample of 1237 adults in Cali, Colombia, we found that in a linear relationship, generalized trust is positively associated with life satisfaction. However, in a model including the interactions between trust and education (...) level as well as between trust and socioeconomic status, generalized trust is found to be negatively associated with life satisfaction. In this non-linear relationship, both education level and socioeconomic status have moderating effects against the negative association between generalized trust and life satisfaction. In other words, less educated people living in worse socioeconomic conditions are more likely to have lower life satisfaction when they have higher levels of social trust. In contrast, highly educated people living in better socioeconomic conditions are more likely to have higher life satisfaction when they have higher levels of social trust. Due to the facilitating function of trust in information processing, lowering the rigor of the filtering system in a high-violence social environment will likely put an individual at risk. Based on our findings, we suggest that policymakers should consider the impacts of social contexts when advocating for increasing social trust. We also recommend that researchers carefully examine the psychological mechanism underlying an observed association before making suggestions for policymaking. (shrink)

Cheating is widely considered a condemnable behavior in society and a big problem in the educational system. In this study, we employ the information-processing-based Bayesian Mindsponge Framework to explore deeper the subjective cost-benefit evaluation involving the perceived value of cheating. Conducting Bayesian analysis on 493 university students from Germany, Vietnam, China, Taiwan, and Japan, we found that students who have more positive attitudes toward cheating are more likely to cheat. However, a higher capability of cognitive reflection acts as a moderator (...) that negates the above effect. Re-evaluation of prior thoughts allows for more accurate assessments of the associated risks and possible costs, which help reduce the probability of carrying out cheating behavior. As rapid technological advancement may introduce new and efficient cheating methods, a better understanding of the psychology of cheating in students can help schools prepare better countermeasures.

A lively debate in the literature on moral progress concerns the role of practical reasoning: Does it enable or subvert moral progress? Rationalists believe that moral reasoning enables moral progress, because it helps enhance objectivity in thinking, overcome unruly sentiments, and open our minds to new possibilities. By contrast, skeptics argue that moral reasoning subverts moral progress. Citing growing empirical research on bias, they show that objectivity is an illusion and that moral reasoning merely rationalizes pre-existing biased moral norms. In (...) this article, I argue that both the rationalists and the skeptics fail to understand fully the role of practical reasoning by focusing exclusively on moral reasoning to the neglect of social reasoning. In the first half of the article, I argue against the skeptics by vindicating moral reasoning. I identify a Democratic Model of moral reasoning which is reliable and effective in overcoming bias. In the second part of the article, I argue against the rationalists. Drawing on a paradigmatic case of moral progress, i.e., the British abolition of the slave trade, I illustrate that moral reasoning, even when sound, is insufficient to motivate progressive action. The explanation for this puzzling phenomenon is not that the moral norm against cruelty is inert, as skeptics might suggest. Rather, it is that the moral norm against cruelty was overridden by the social norm of slavery which was tied to the British joint commitments to freedom and national honour. The debate between rationalists and skeptics centers around the moral rationality of human action, failing to recognize that human action is in fact primarily about social rationality. I defend a joint commitment account of social rationality, and offer a novel Communitarian Model of social reasoning which follows the logic of social rationality to revise social norms. I defend the reliability and efficacy of the Communitarian Model of social reasoning by applying it to the abolitionist social movement to show how Britons gave fellow Britons social reasons grounded in their joint commitments to freedom and national honour to end slavery.

In the trust-health relationship, how trusting other people in society may promote good health is a topic often examined. However, the other direction of influence – how health may affect trust – has not been well explored. In order to investigate this possible effect, we employed Bayesian Mindsponge Framework (BMF) analytics to go deeper into the information processing mechanisms underlying the expressions of trust. Conducting Bayesian analysis on a dataset of 1237 residents from Cali, Colombia, we found that general health (...) status is positively associated with generalized trust, but recent experiences of illnesses/injuries have a negative moderating effect. Personalized trust is largely unchanged across different general health conditions, but the trust level becomes higher with recent experiences of illnesses/injuries. Psychophysiological mechanisms of increasing information filtering intensity toward unfamiliar sources during a vulnerable state of health is a plausible explanation of found patterns in generalized trust. Because established personal relationships are reinforced information channels, personalized trust is not affected as much. Rather, the results suggest that people may rely even more on loved ones when they are in bad health conditions. This exploratory study shows that the trust-health relationship can be examined from a different angle that may provide new insights. (shrink)

Person‐centred care is founded on ethics as a basis for organizing care. In spite of healthcare systems claiming that they have implemented person‐centred care, patients report less satisfaction with care. These contrasting results require clarification of how to practice person‐centred ethics using Paul Ricoeur's ‘Little ethics’, summarized as: ‘aiming for the good life, with and for others in just institutions’. In this ethic Kantian morality is at once subordinate and complementary to Aristotelian ethics because the ethical goal needs to be (...) critically assessed and passed through the examination of the norm in each care situation. This paper presents examples that describes a person‐centred care practice that balance a critical review of care activities based on a conviction of aiming for patients' wellbeing. In contrast to patients' experiences of person‐centred care in real life, research projects have shown that if the clinical performers comprehend and apply the practice of person‐centred ethics, patients report positive outcomes. The implementation of person‐centred care therefore demands that stakeholders and managers enables and requires that healthcare staff study ethics in the same way as studying for example pharmacology is required when handling patients' medicines.

Subjective and psychophysiological emotional responses to music from two different cultures were compared within these two cultures. Two identical experiments were conducted: the first in the Congolese rainforest with an isolated population of Mebenzélé Pygmies without any exposure to Western music and culture, the second with a group of Western music listeners, with no experience with Congolese music. Forty Pygmies and 40 Canadians listened in pairs to 19 music excerpts of 29–99 s in duration in random order (eight from the (...) Pygmy population and 11 Western instrumental excerpts). For both groups, emotion components were continuously measured: subjective feeling (using a two- dimensional valence and arousal rating interface), peripheral physiological activation, and facial expression. While Pygmy music was rated as positive and arousing by Pygmies, ratings of Western music by Westerners covered the range from arousing to calming and from positive to negative. Comparing psychophysiological responses to emotional qualities of Pygmy music across participant groups showed no similarities. However, Western stimuli, rated as high and low arousing by Canadians, created similar responses in both participant groups (with high arousal associated with increases in subjective and physiological activation). Several low-level acoustical features of the music presented (tempo, pitch, and timbre) were shown to affect subjective and physiological arousal similarly in both cultures. Results suggest that while the subjective dimension of emotional valence might be mediated by cultural learning, changes in arousal might involve a more basic, universal response to low-level acoustical characteristics of music.

Precognition is an anomaly in information transmission and interpretation. Extant literature suggests that paranormal beliefs and gender may have significant influences on this unknown information process. This study examines the effects of these two factors, including their interactions, on precognition performance by employing the Bayesian Mindsponge Framework (BMF) analytics. Using Bayesian analysis on secondary data of 60 participants, we found that men may have higher chances to score a hit in a precognition task compared to women. Interestingly, stronger beliefs in (...) the paranormal may decrease the success probability in performing precognition tasks. Considering the interactions between the two factors, the effect of paranormal beliefs on precognition task performance is stronger in men than women. Using mindsponge-based reasoning, we argue that paranormal beliefs may increase the interference of imagination in the reception of hypothetical precognitive information. Women tend to rely more on intuition, which may lessen the interference effect of imagination on hypothetical psi reception. Based on the findings, we suggest that researchers should be careful when assessing participants’ psi potential for experiments. We also demonstrate some advantages of utilizing the BMF in parapsychological research. (shrink)

Reviewing the literature on political participation and civic engagement, the article offers a critical examination of different conceptual frameworks. Drawing on previous definitions and operationalisations, a new typology for political participation and civic engagement is developed, highlighting the multidimensionality of both concepts. In particular, it makes a clear distinction between manifest “political participation” (including formal political behaviour as well as protest or extra-parliamentary political action) and less direct or “latent” forms of participation, conceptualized here as “civic engagement” and “social involvement”. (...) The article argues that the notion of “latent” forms of participation is crucial to understand new forms of political behaviour and the prospects for political participation in different countries. Due to these innovations it contributes to a much-needed theoretical development within the literature on political participation and citizen engagement. (shrink)

Our study examines how a company’s engagement in corporate social responsibility influences word of mouth about the company on Twitter, particularly during a service delay. We use the airline industry as the study context. On the popular social medium Twitter, people post tweets about airline services and raise concerns about service delays when flights are delayed, canceled, or diverted. Drawing on the literature on legitimacy and the halo effect, we argue that a company’s CSR engagement enhances its corporate image, which (...) in turn, influences WOM about the company on Twitter. We predict and find that airlines with better CSR engagement receive more positive word of mouth and less negative word of mouth on Twitter. We also find that service delays reduce PWOM and increase NWOM, with the additional finding that the positive relationship between service delays and NWOM is less strong for airlines with better CSR engagement. We conduct additional analyses to investigate the effects of environmental, social, and governance CSR on PWOM and NWOM. Our study has practical implications in informing companies about the benefits of CSR engagement in relation to public opinion during service delays. (shrink)

Food prices are a daily concern in many households’ decision-making, especially when people want to have healthier diets. Employing Bayesian Mindsponge Framework (BMF) analytics on a dataset of 710 Indonesian citizens, we found that people from wealthier households are less likely to have concerns about food prices. However, the degree of health considerations in food consumption was found to moderate against the above association. In other words, people of higher income-based social classes may worry more about food prices if they (...) care more about the health impacts of their food choices. These findings provide more insights for policymakers on the psychological aspects of promoting the balance between finance and health in food consumption. (shrink)

Breast cancer and cervical cancer are major contributors to morbidity and mortality among Vietnamese Canadian women. Vietnamese women are at risk because of their low participation rate in cancer‐preventative screening programmes. Drawing from the results of a larger qualitative study, this paper reports factors that influence Vietnamese women's participation in breast and cervical cancer screening from the healthcare providers’ perspectives. The women participants’ perspective was reported elsewhere.Semistructured interviews were conducted with six healthcare providers. Analysis of these interviews reveals several challenges (...) which healthcare providers encountered in their clinical practice. These include the physicians’ cultural awareness about the private body, patient's low socioeconomic status, the healthcare provider–patient relationship, and limited institutional support.This is the first Canadian study to identify the healthcare providers’ perspective on giving breast and cervical cancer preventive care to the Vietnamese immigrant women. The insight gained from these healthcare providers’ experiences are valuable and might be helpful to healthcare professionals caring for immigrant women of similar ethno‐cultural backgrounds. Recommendations for the promotion of breast cancer and cervical cancer screening among Vietnamese women include: (i) effort should be made to recruit Vietnamese‐speaking female healthcare professionals for breast and cervical health‐promotion programmes; (ii) reduce woman–physicians hierarchical relationship and foster effective doctor–patient communication; (iii) healthcare providers must be aware of their own cultural beliefs, values and attitudes that they bring to their practice; and (iv) more institutional support and resources should be given to both Vietnamese Canadian women and their healthcare providers.

The increasing number of immigrants in Canada has led to more nursing students for whom English is an additional language (EAL). Limited language skills, cultural differences, and a lack of support can pose special challenges for these students and the instructors who teach them. Using a qualitative research methodology, in‐depth interviews with fourteen EAL nursing students and two focus group interviews with nine instructors were conducted. In this paper, the instructors' perspectives are presented. Data acquired from the instructors suggest that (...) the challenges experienced by EAL students and instructors reside in a lack of awareness and support at the institutional and structural levels rather than solely on capacities of individual EAL students or instructors. From this study, identification of supportive activities for nurse educators and education sector decision makers emerged. (shrink)

Understanding how healthcare responsibility is distributed will give insight on how health‐care is delivered and how members of a society are expected to practice health‐care. The raising cost of health‐care has resulted in restructuring of the existing Canadian healthcare system toward a system that controls costs by placing more healthcare responsibility on the individual. This shift might create more difficulty for immigrants and refugees to obtain equitable health‐care and put blame on them when they experience illness. This paper is drawn (...) from the results of a larger qualitative study exploring Vietnamese Canadian women's breast cancer and cervical cancer screening practices. Interview data were gathered from 15 Vietnamese Canadian women and six healthcare providers. We will demonstrate that (a) despite the strong influence of individualism, Vietnamese women and their healthcare providers value both individual liberty and the interrelationship between individual and society; (b) limited funding and unequal distribution of healthcare resources impacted how immigrant and refugee women practice health‐care. Thus, motivating and fostering immigrant and refugee women's healthcare practice require both individual and institutional effort. To foster immigrant and refugees’ healthcare practices, healthcare policy makers and providers need to consider how to distribute healthcare resources that meet immigrants’ and refugees’ healthcare needs in the most equitable way.

A new approach to the 'hard problem'of consciousness, the eons-old mind-body problem, is proposed, inspired by Whitehead, Schopenhauer, Griffin, and others. I define a 'simple subject' as the fundamental unit of matter and of consciousness. Simple subjects are inherently experiential, albeit in a highly rudimentary manner compared to human consciousness. With this re-framing, the 'physical' realm includes the 'mental' realm; they are two aspects of the same thing, the outside and inside of each real thing. This view is known as (...) panpsychism or panexperientialism and is in itself a partial solution to the hard problem. The secondary but more interesting question may be framed as: what is a 'complex subject'? How do simple subjects combine to form complex subjects like bats and human beings? This is more generally known as the 'combination problem'or the 'boundary problem', and is the key problem facing both materialist and panpsychist approaches to consciousness. I suggest a new approach for resolving this component of the hard problem, a 'general theory of complex subjects' that includes 'psychophysical laws' in the form of a simple mathematical framework. I present three steps for characterizing complex subjects, with the physical nature of time key to this new understanding. Viewing time as fundamentally quantized is important. I also suggest, as a second-order conceptualization, that 'information' and 'experience' may be considered identical concepts and that there is no double-aspect to information. Rather, there is a single aspect to information and it is inherently experiential. Tononi's, Chalmers', and Freeman's similar theories are compared and contrasted. (shrink)

Artificial intelligence has dramatically changed the way organizations communicate, understand, and interact with their potential consumers. In the context of this trend, the ethical considerations of advertising when applying AI should be the core question for marketers. This paper discusses six dominant algorithmic purchase decision pathways that align with ethical philosophies for online customers when buying a product/goods. The six ethical positions include: ethical egoism, deontology, relativist, utilitarianism, virtue ethics, and ethics of care. Furthermore, this paper launches an “intelligent advertising” (...) AI theme by examining its present and future as well as identifying the key phases of intelligent advertising. Several research questions are offered to guide future research on intelligent advertising to benefit ethical AI decision-making. Finally, several areas that can be widely applied to ethical intelligent advertising are suggested for future research. (shrink)

After employing the mindsponge mechanism and 3D information process of creativity to explain the serendipity process in previous chapters, we realize that it may be helpful to delve into the relations between serendipity and the formulation of new values and information connections through non-linear processes. Thus, this chapter summarizes some preliminary attempts to use non-linear information processes to explain serendipity. We also briefly mention the benefits of information exchange among members of social groups and explain this approach.

Where is consciousness? Neurobiological theories of consciousness look primarily to synaptic firing and “spike codes” as the physical substrate of consciousness, although the specific mechanisms of consciousness remain unknown. Synaptic firing results from electrochemical processes in neuron axons and dendrites. All neurons also produce electromagnetic (EM) fields due to various mechanisms, including the electric potential created by transmembrane ion flows, known as “local field potentials,” but there are also more meso-scale and macro-scale EM fields present in the brain. The functional (...) role of these EM fields has long been a source of debate. We suggest that these fields, in both their local and global forms, may be the primary seat of consciousness, working as a gestalt with synaptic firing and other aspects of neuroanatomy to produce the marvelous complexity of minds. We call this assertion the “electromagnetic field hypothesis.” The neuroanatomy of the brain produces the local and global EM fields but these fields are not identical with the anatomy of the brain. These fields are produced by, but not identical with, the brain, in the same manner that twigs and leaves are produced by a tree’s branches and trunk but are not the same as the branches and trunk. As such, the EM fields represent the more granular, both spatially and temporally, aspects of the brain’s structure and functioning than the neuroanatomy of the brain. The brain’s various EM fields seem to be more sensitive to small changes than the neuroanatomy of the brain. We discuss issues with the spike code approach as well as the various lines of evidence supporting our argument that the brain’s EM fields may be the primary seat of consciousness. This evidence (which occupies most of the paper) suggests that oscillating neural EM fields may make firing in neural circuits oscillate, and these oscillating circuits. may help unify and guide conscious cognition.

This study examines how the match between personal and firm-level values regarding environmental responsibility affects employee job satisfaction and creativity and contributes to three literature streams [i.e., social corporate responsibility, creativity, and person–environment fit]. Building on the P–E fit literature, we propose and test environmental orientation fit versus nonfit effects on creativity, identifying job satisfaction as a mediating mechanism and regulatory pressure as a moderator. An empirical investigation indicates that the various environmental orientation fit conditions affect job satisfaction and creativity (...) differently. More specifically, environmental orientation fit produces greater job satisfaction and creativity when the employee and organization both demonstrate high concern for the environment than when both display congruent low concern for the environmental. Furthermore, for employees working in organizations that fit their personal environmental orientation, strong regulatory pressure to comply with environmental standards diminishes the positive fit effect on job satisfaction and creativity, while regulatory pressure does not affect the job satisfaction and creativity of employees whose personal environmental orientation is incongruent with that of the organization.

Patients with serious illnesses or injuries may decide to quit their medical treatment if they think paying the fees will put their families into destitution. Without treatment, it is likely that fatal outcomes will soon follow. We call this phenomenon “near-suicide”.

Bayesian Mindsponge Framework (BMF) analytics were employed to analyze a dataset of 1042 Vietnamese patients. We found that the more serious the illnesses or injuries of patients were, the more likely they were to choose to quit treatment if they perceived that paying the treatment fees heavily affected their families’ financial status. Particularly, only one in four patients with the most serious health issues who thought that continuing the treatment would push themselves and their families into destitution would decide to continue the treatment. Considering the information-filtering mechanism using subjective cost–benefit judgments, these patients likely chose the financial well-being and future of their family members over their individual suffering and inevitable death. Our study also demonstrates that mindsponge-based reasoning and BMF analytics can be effective in designing and processing health data for studying extreme psychosocial phenomena. Moreover, we suggest that policymakers implement and adjust their policies (e.g., health insurance) following scientific evidence to mitigate patients’ likelihood of making “near-suicide” decisions and improve social equality in the healthcare system.

Environmental influences on the experiences of people with Parkinson’s diseaseThis study elucidates environmental influences on lived illness experiences. For two consecutive years, persons with Parkinson’s disease (PD) participated in 1 week of daily walking in the Swedish mountains. Daily, low‐intensive walking that is free of intense effort or time pressures associated with group interaction characterized the week. Participants were interviewed 3 months after the mountain stay regarding experiences in the mountains, daily living, and how their experience in the mountains influenced (...) their daily living after returning home. A phenomenological method was used for data analysis. Results point to the close connection between mind, body, and environment. The connection becomes highlighted when people are afflicted with sickness, such as PD, which causes impaired control of body language, impaired voluntary mobility, and lowered energy levels. The results also show how a social context in an environment with suitable physical challenges led to a change in individuals’ perceptions of the manageability of their experienced sicknesses. These results provide a deepened understanding of how individuals with PD experience illness, its influences on daily life, and how a suitable environment opens opportunities for managing daily issues.

China is establishing its corporate governance structures by emulating the stylized Anglo-American model. However, the country does not yet have the necessary formal and informal institutions, or the financial infrastructure to make these structures work effectively.

M. xanthus has a complex multicellular lifestyle including swarming, predation and development. These behaviors depend on the ability of the cells to achieve directed motility across solid surfaces. M. xanthus cells have evolved two motility systems including Type‐IV pili that act as grappling hooks and a controversial engine involving mucus secretion and fixed focal adhesion sites. The necessity for cells to coordinate the motility systems and to respond rapidly to environmental cues is reflected by a complex genetic network involving at (...) least three complete sets of chemosensory systems and eukaryotic‐like signaling proteins. In this review, we discuss recent advances suggesting that motor synchronization results from spatial oscillations of motility proteins. We further propose that these dynamics are modulated by the action of multiple upstream complementary signaling systems. M. xanthus is thus an exciting emerging model system to study the intricate processes of directed cell migration. BioEssays 30:733–743, 2008. © 2008 Wiley Periodicals, Inc. (shrink)
