In this study we analyze daily data on television viewing in the Netherlands. We postulate hypotheses on supply and demand factors that could impact the amount of daily viewing time. Although the general assumption is that supply and demand often correlate, we see that for television this is only marginally the case. Especially diversity of program supply, often deemed very important in media markets, does not affect (positively or negatively) television viewing behavior. Most variation in television viewing can (...) be attributed to habit and to regular events (e. g. weekends, Christmas) and to unexpected events (e. g. the 9/11 WTC attack). We also find that weather conditions interact with program types, so that, for example, in winter times people favor entertainment programs even more, suggesting that people use television for mood management.

A series of recent debates in experimental economics have associated demand effects with the artificiality of the experimental setting and have linked it to the problem of external validity. In this paper, we argue that these associations can be misleading, partly because of the ambiguity with which “artificiality” has been defined, but also because demand effects and external validity are related in complex ways. We argue that artificiality may be directly as well as inversely correlated with demand (...) effects. We also distinguish between the demand effects of experimentation and the reactions that they may trigger and that might endanger experimental validity. We conclude that economists should pay more attention to the way in which subjects construe the experimental task and learn to exploit subjects’ reactivity to expectations in their experiments.

As a stress test of experimenter demand effects, we run an experiment where subjects can physically destroy coupons awarded to them. About one subject out of three does. Giving money back to the experimenter is possible in a separate task but is more consistent with an experimenter demand effect than an explanation based on altruism towards the experimenter. A measure of sensitivity to social pressure helps predict destruction when social information is provided.

Performance Generating Systems (PGS) are rule- and task-based approaches to improvisation on stage in theatre, dance, and music. These systems require performers to draw on predefined source materials (texts, scores, memories) while working on complex tasks within limiting rules. An interdisciplinary research team at a large Western Canadian university hypothesized that learning to sustain this praxis over the duration of a performance places high demands on executive functions; demands that may improve the performers’ executive abilities. These performers need to continuously (...) shift attention while remaining responsive to embodied and environmental stimuli in the present, they are required to inhibit automated responses and impulses using the rules of the system, and they strive towards addressing multitasking challenges with fluidity and flexibility. This study set out to test the mentioned hypothesis deductively and identify mediating processes inductively, using mixed empirical methods. In a small sample experiment with a control group (28 participants; 15 in intervention group, 13 in control group), standardized quantitative tests of executive functions (D-KEFS) were administered before and after an eight-week intervention. Participant-reported qualitative observations from the praxis were also collected throughout the intervention for grounded analysis. Within the limitations of small sample data, we found both statistically significant and trending effects on inhibition, problem-solving initiation, fluidity, and cognitive flexibility. Examining the mediating process, we found that participants experienced significant challenges sustaining the practice halfway through the intervention. The participant-reported solutions to these challenges, which emerged as the strongest behavioural patterns when coding the qualitative data to saturation, were strategies of problem-solving and of re-directing attention. These strategies support and advance our understanding of the effects measured in the standardized tests. In terms of application, our results identify characteristics of PGS that could potentially maintain and strengthen executive functions over and above less demanding performing arts interventions. The results also deliver new insight into how PGS works, which may contribute to the development and teaching of this artistic practice. (shrink)

The unconscious-thought effect occurs when distraction improves complex decision making. Recent studies suggest that this effect is more likely to occur with low- than high-demanding distraction tasks. We discuss implications of these findings for Newell & Shanks' (N&S's) claim that evidence is lacking for the intervention of unconscious processes in complex decision making.

Effectiveness, efficiency and equity in health care are discussed in this article against the background of concerns that cost containment may lead to reductions in quality of care. It is suggested that effectiveness is best seen from the patient's point of view and that it relates to more than simply improved health status. Efficiency and equity are better viewed from a societal stance.The paper discusses the role of the medical profession in effectiveness, efficiency and equity and argues that the role (...) of medical doctors needs to be constrained.

Technical reasoning refers to making inferences about how to use tools. The degree of technical reasoning is indicated by the bias of the gaze on the functional part of the tool when in use. Few studies have examined whether technical reasoning differs between familiar and unfamiliar novel tools. In addition, what effect the intention to use the tool has on technical reasoning has not been determined. This study examined gaze shifts in relation to familiar or unfamiliar tools, under three (...) conditions, among 14 healthy adults. The cumulative fixation time on the functional part of the tool served as a quantitative indicator of the degree of technical reasoning. The two-way analysis of variance for tools and conditions revealed that the cumulative fixation time significantly increased under free viewing and use conditions, compared to lift conditions. Relative to the free viewing condition, cumulative fixation time for unfamiliar tools significantly decreased in the lift condition and significantly increased in the use condition. Importantly, the results showed that technical reasoning was performed in both the use and the free viewing conditions. However, technical reasoning in the free viewing condition was not as strong as in the use condition. The difference between technical reasoning in free viewing and use conditions may indicate the difference between automatic and intentional technical reasoning. (shrink)

The deposit insurance makes the value of deposits independent from the behavior of other depositors or from the value of bank assets. Its existence induces a moral hazard which might threaten the stability of the banking system. The efficiency of the DI depends on the control of moral hazard, which means the agents’ responsibilisation, depositors included. There is a conflict between the DI principles and the present propositions improving this mechanism.The possible solutions in order to solve this paradox are the (...) restriction of the insurance coverage only for the demand deposits and the implementation of the double liability for the bank shareholders.The demand deposits insurance eliminates the incentive to bank runs caused by the fear of lack of liquidity, whereas the term deposits are exposed to losses which reduce the moral hazard induced by the demand deposit insurance.The double liability forces the shareholders of the defaulting banks to make supplementary payments limited to the nominal value of the owned shares. This combines the advantages of the limited liability and the unlimited liability.The efficiency of both propositions implies the enforcement of a closure rule of the banks whose net worth is close to zero.La garantie des dépôts rend la valeur des dépôts indépendante du comportement des autres déposa- nts ou de la valeur des actifs bancaires. Son instauration induit un aléa moral qui peut menacer la stabilité du système bancaire. L’efficacité de ce mécanisme dépend de la maîtrise de l’aléa moral. Cela suppose, entre autres, la responsabilisation des agents, y compris des déposants. Par conséquent, il existe un conflit entre le principe de la garantie des dépôts et les propositions courantes d’amélioration de ce dispositif.Les solutions envisagées dans cet article pour résoudre ce paradoxe sont la limitation de la garantie aux seuls dépôts à vue et l’instauration de la double responsabilité pour les actionnaires des banques.La garantie des dépôts à vue élimine l’incitation à la ruée due à la crainte de manque de liquidité, tandis que les dépôts à terme sont assortis d’une clause permettant à la banque de refuser tout retrait anticipé. Les titulaires des dépôts à terme s’exposent à des pertes, ce qui réduit l’aléa moral induit par la garantie des dépôts à vue.La double responsabilité oblige les actionnaires des banques défaillantes à effectuer des versements supplémentaires dans la limite de la valeur nominale des actions détenues. Cela réunit les avantages de la responsabilité limitée et de la responsabilité illimitée.L’efficacité des deux propositions suppose l’application d’une règle de fermeture des banques dont l’actif net avoisine zéro.

The gaze cueing effect is characterized by faster attentional orienting to a gazed-at than a non-gazed-at target. This effect is often enhanced when the gazing face bears an emotional expression, though this finding is modulated by a number of factors. Here, we tested whether the type of task performed might be one such modulating factor. Target localization and target discrimination tasks are the two most commonly used gaze cueing tasks, and they arguably differ in cognitive resources, which could (...) impact how emotional expression and gaze cues are integrated to orient attention. In a within-subjects design, participants performed both target localization and discrimination gaze cueing tasks with neutral, happy, and fearful faces. The gaze cueing effect for neutral faces was greatly reduced in the discrimination task relative to the localization task, and the emotional enhancement of the gaze cueing effect was only present in the localization task and only when this task was performed first. These results suggest that cognitive resources are needed for gaze cueing and for the integration of emotional expressions and gaze cues. We propose that a shift toward local processing may be the mechanism by which the discrimination task interferes with the emotional modulation of gaze cueing. The results support the idea that gaze cueing can be greatly modulated by top-down influences and cognitive resources and thus taps into endogenous attention. Results are discussed within the context of the recently proposed EyeTune model of social attention. (shrink)

Stereotype threat—a situational context in which individuals are concerned about confirming a negative stereotype—is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co-opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability. We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth-grade students provided either their race or the date before a videotaped, (...) conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated.

Brain lateralization of lexical tone processing remains a matter of debate. In this study we used a dichotic listening paradigm to examine the influences of the knowledge of Jyutping, linguistic-processing demand and tone type on the ear preference pattern of native tone processing in Hong Kong Cantonese speakers. While participants with little knowledge of Jyutping showed a previously reported left-ear advantage, those with a good level of Jyutping expertise exhibited either a right-ear advantage or bilateral processing during lexical tone (...) identification and contour tone discrimination, respectively. As for the effect of linguistic-processing demand, while an LEA was found in acoustic/phonetic perception situations, this advantage disappeared and was replaced by a bilateral pattern in conditions that involved a greater extent of linguistic processing, suggesting an increased involvement of the left hemisphere. Regarding the effect of tone type, both groups showed an LEA in level tone discrimination, but only the Jyutping group demonstrated a bilateral pattern in contour tone discrimination. Overall, knowledge of written codes of tones, greater degree of linguistic processing and contour tone processing seem to influence the brain lateralization of lexical tone processing in native listeners of Cantonese by increasing the recruitment of the left-hemisphere language network.

All capitalist economies experience fluctuations in employment and economic activity around a long-term growth rate. How is this cyclical pattern of growth to be explained? Are the causes of fluctuations in output and employment to be found outside the system or are they intrinsic to the system? Will the long-term growth rate correspond to the growth of the labour force? It is the search for answers to these questions which motivates Peter Skott's analysis. The book develops a theory of dynamic (...) interaction between three types of agent: firms, households and banks. Firms are profit-maximisers operating under conditions of imperfect competition and their production and investment decisions are influenced by monetary and financial factors as well as by the state of the labour market. Households hold financial assets, supply labour and have a direct influence on nominal wage rates. Banks set interest rates on bank loans and deposits. No assumptions are made about nominal price rigidities and the capital-output ratio is determined endogenously. Using a framework of analysis which is rigorous and which does not exclude traditional neoclassical mechanisms, this book demonstrates the validity of important Marxian and Keynesian insights into the growth process.

This study examined whether worktime control buffered the impact of worktime demands on work-family interference (WFI), using data from 2,377 workers from various sectors of industry in The Netherlands. We distinguished among three types of worktime demands: time spent on work according to one's contract (contractual hours), the number of hours spent on overtime work (overtime hours), and the number of hours spent on commuting (commuting hours). Regarding worktime control, a distinction was made between having control over days off and (...) vacations (leave control) and having control over starting and finishing times (flextime). These three worktime demands were expected to have separate as well as joint effects on WFI, whereas worktime control should buffer these adverse effects of worktime demands on WFI. Stepwise regression analyses showed that working high numbers of contractual and overtime hours was indeed associated with high WFI. Further, worktime control indeed made a difference in terms of WFI: whereas leave control contributed directly to lower WFI, flextime buffered the adverse effects of long contractual workhours. Our results suggest that very long working days should be prevented, and that worktime control may be a powerful tool to help workers maintaining a good work-family balance. (shrink)

Pragmatist responses to skepticism about empirical justification have mostly been underwhelming, either presupposing implausible theses like relativism or anti-realism, or else showing our basic empirical beliefs to be merely psychologically inevitable rather than rationally warranted. In this paper I defend a better one: a modified version of an argument by Wilfrid Sellars that we are pragmatically warranted in accepting that our perceptual beliefs are likely to be true, since their likely truth is necessary for the satisfaction of our goal of (...) effective agency. On the version of the argument I defend, the great good for human life of control over our empirical circumstances renders our goal of effective agency reasonable. But only if our perceptual beliefs are likely to be true—and only if we accept that this is so, assuming it as a premise for inference and a guide for action—will the success of our actions be due to our effective agency, not mere luck. Since we’re warranted in taking the necessary means to our reasonable ends, we’re warranted in accepting that our perceptual beliefs are generally justified, and so that skepticism about empirical justification is false.

Effective altruists either believe they ought to be, or strive to be, doing the most good they can. Since they’re human, however, effective altruists are invariably fallible. In numerous situations, even the most committed EAs would fail to live up to the ideal they set for themselves. This fact raises a central question about how to understand effective altruism. How should one’s future prospective failures at doing the most good possible affect the current choices one makes as an effective altruist? (...) This question is important to answer not only because every effective altruist will face this question due to typical human akrasia, but also because how the question is answered will determine just how demanding effective altruism can be. I argue that no matter how effective altruists answer this question, they will have to take on some commitments seemingly antithetical to their movement. More precisely, I argue that effective altruism is subject to a dilemma. Effective altruists’, at times, implicit actualist assumptions (i) commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (ii) undermine effective altruists’ arguments against moral offsetting and giving to charities close to the heart. Yet, effective altruists’, at times, implicit possibilist assumptions (iii) also commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (iv) undermine typical responses to demandingness worries for the normative conception of effective altruism. I argue that the best way out of the dilemma is to accept hybridism, though even hybridism won’t preserve every commitment of effective altruism. (shrink)

Maxwell et al. [Maxwell, J. P., Masters, R. S. W., Kerr, E., & Weedon, E. . The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068. The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068] suggested that, following unsuccessful movements, the learner forms hypotheses about the probable causes of the error and the required movement adjustments necessary for its elimination. Hypothesis testing is an explicit process that places demands on (...) cognitive resources. Demands on cognitive resources can be identified by measuring probe reaction times and movement times. Lengthened PRT and movement times reflects increased cognitive demands. Thus, PRT and movement times should be longer following errors, relative to successful, movements. This hypothesis was tested using a motor skill . Furthermore, the association between error processing and the preparation and execution phases of movement was examined. The data confirmed that cognitive demand is greater for trials following an error, relative to trials without an error. This effect was apparent throughout learning and in both the preparatory and execution phases of the movement. Cognitive effort also appeared to be higher during movement preparation, relative to movement execution. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Demanding Environmental Ethics for the FutureJames P. Sterba (bio)As we contemplate the present and future effects of global climate change, it is hard not to be disillusioned by what we see. Melting glaciers, rising sea levels, more intense and erratic weather patterns, wide-scale extinction of endangered species—what can we as environmental philosophers do that might be helpful in this regard? My suggestion is that we respond by drawing (...) on the resources of traditional normative philosophy to ground a demanding environmental ethics that will justify the kind of sacrifices that are needed to cope with our unsettling future.This is a project that, with a lot of help from others, I have been working on for the last twenty years. I will present it, at least in outline, in my presidential address at the APA Central Division Meeting next spring, entitled "Completing the Kantian Project: From Rationality to Equality." By equality here I mean substantive intergenerational equality. This will require that we limit our current use of resources to simply meeting our basic needs. So the argument moves from a neutral nonmoral rational foundation to a very demanding set of practical moral requirements. So far sketched, the argument does not yet take into account the requirements that nonhuman living nature places upon us. But surprisingly, so demanding is this morality as sketched so far, that when additional considerations are introduced to take nonhuman living nature into account, not much more is required of us other thansome further constraints on population policy.Now I know some environmental philosophers are more skeptical than I am about the usefulness of traditional moral philosophy. Even I am unhappy with certain debates currently raging among contemporary moral philosophers, such as the realist/anti-realist debate. In fact, my argument is designed to make that very debate unnecessary. Still, if we leave most of traditional moral philosophy behind, what do we as philosophers bring with us to the new disciplines with which we now propose to collaborate? Do we bring an ability to do values clarification and a good sense of argument? I don't think these skills and others like them alone will be enough for the task at hand. We need a very demanding ethics, and if we don't look to philosophy to ground such an ethics, where do we look? [End Page 146]There is also an additional advantage here to grounding a demanding environmental ethics in traditional normative philosophy. Such an approach is more likely to force traditionalists and conservatives, philosophers and otherwise, to take notice of our arguments. If we are out in "left" field just talking to those both inside and outside of philosophy who happen to agree with our practical agenda, it is easier for us to be dismissed by others who are not committed to that same practical agenda. By contrast, if we address our opponents by appealing to very traditional values by which they claim to live their lives, then we do have at least a fighting chance of changing the way they do live their lives. At least, as moral philosophers, we would have then done our best to respond to the environmental crisis. Provided of course that we are also willing to reach out with our demanding ethics in hand and do that interdisciplinary collaboration that needs to be done to secure fully practical and effective solutions to the problems we face.James P.

The food and package delivery workforce in China has grown substantially in the past decade. However, delivery drivers face volatile and stressful work conditions, which can give rise to high turnover and burnout. Past research has indicated that job demands and resources significantly predict burnout. Scholars have also found evidence that mindfulness may be a protective factor against negative outcomes like burnout. Using data collected from 240 food and package delivery drivers in Beijing, China, we examined the effects of JD-R (...) on burnout and whether these relations were moderated by mindfulness. Estimates produced by regression analyses indicated that job demands have significantly positive effects on burnout, while job resources have a significant negative effect on burnout. Mindfulness significantly moderated the effects of JD and JR on burnout. Results suggest that mindfulness is a protective factor for delivery drivers. Practice and policy implications are discussed.

Through the continuous investigation of humans in organizations, we have learned much about motivation, attitudes, and performance. For example, Yukl and others have helped increase our understanding of influence tactics and the effect they have on the performance of subordinates, supervisors, and peers. Some tactics (and combinations of tactics) lead to resistance, some lead to compliance, and some lead to commitment. In this study, we raise the question of whether or not we incorporate our knowledge of these research findings (...) into the design, implementation, and interpretation of our own research studies that require the participation of human subjects. In a survey of 134 subjects from a previous social science study, we found that performance varied across the sample, consistent with the concepts of resistance, compliance, and commitment. In addition, the variance in performance could be explained, in part, by task interest and perceived task demands. Implications are discussed. (shrink)

In global business, business organizations and their representatives frequently encounter corruption and may be the perpetrators, victims, or simply participants in such acts. While international corruption has existed in multiple forms for several years, many individuals, companies, nations, and international organizations are currently attempting to reduce or eliminate corrupt acts because of their harmful effects on local economies and the quality of life of citizens. Several of these corruption curtailment efforts have been directed toward the supply-side of corruption, i.e., those (...) who make corrupt payments. In developing an understanding of corruption, however, and formulating strategies for its reduction, consideration must also be given to the demand-side of corruption, i.e., those who demand and accept corrupt payments. Accordingly, this study examined the demand-side of corruption and several related factors in the categories of government, economy and poverty, education, geography, and culture. Analysis of these factors employed the Corruption Perceptions Index (CPI), formulated annually by Transparency International (TI), and other sources. Several factors in each of the five categories were found to correlate significantly with perceived corruption, and strategies for addressing these issues were developed and discussed. (shrink)

Effective Altruism encourages affluent people to make significant donations to improve the wellbeing of the world’s poor, using quantified and observational methods to identify the most efficient charities. Critics argue that EA is inattentive to the systemic causes of poverty and underestimates the effectiveness of individual contributions to systemic change. EA claims to be open to systemic change but suggests that systemic critiques, such as the socialist critique of capitalism, are unhelpfully vague and serve primarily as hypocritical rationalizations of continued (...) affluence. I reformulate the systemic change objection, rebut the charges of vagueness and bad faith and argue that charity may not be worth doing at all from a purely altruistic perspective. In order to take systemic change seriously, EA must repudiate its narrowly empiricist approach, embrace holistic, interpretive social analysis and make inevitably controversial judgments about the complex dynamics of collective action. These kinds of evidence and judgment cannot be empirically verified but are essential to taking systemic change seriously. EA is thereby forced to sacrifice its a-political approach to altruism. I also highlight the importance of quotidian, extra-political contributions to perpetuating or changing harmful social practices. Radical efforts to resist, subvert and reconstruct harmful social practices, such as those involved in economic decision-making, could be just as effective and demanding as charity. But such efforts may be incompatible with extensive philanthropy, because they can require people to retain some level of affluence for strategic reasons but to repudiate both the acquisition of significant wealth and charity as is currently organized. The wealth and status of some critics of charity may indeed be incompatible with effectively contributing to social change, but the altruistic merits of charity are neither as obvious nor as easily demonstrated as EA believes.

With the emergence of environmental sustainability and green business management, increasing demands have been made on businesses in the areas of environmental corporate social responsibility. Furthermore, the influence of ECSR on green capital investment, environmental performance, and business competitiveness has also been the subject of attention from enterprises. However, in previous studies, the mediating role of green information technology capital in the relationship between ECSR, environmental performance, and business competitiveness, has not been investigated by researchers. In order to bridge this (...) gap in the ECSR literature, this study aims to examine the influence of ECSR on green IT capital, and the consequent effect of green IT capital on environmental performance and business competitiveness. Data were collected from 358 companies from the top 1000 manufacturers in Taiwan. The results confirmed that ECSR has significant positive effects on green IT human capital, green IT structural capital, and green IT relational capital. Green IT structural capital and green IT relational capital have positive effects on environmental performance and business competitiveness, and environmental performance has a positive effect on business competitiveness. In addition, green IT structural capital and green IT relational capital have partial mediating effects on ECSR, environmental performance, and business competitiveness. The implications and suggestions for future research are discussed. (shrink)

Literature shows that psychological phenomena, including values, personality, and behaviors, are geographically clustered. The effects of temperature on interpersonal and intergroup aggression have been studied by many social psychologists. To date the interactions between temperature and other geographical factors have not been addressed. This study is aiming to examine the effects of thermal demands and the moderating effects of natural geographical factors on aggressive behavior at national level. Data for 156 societies was obtained from publicly available databases. Consistent with the (...) life-history theory, results of this study showed that aggressive behavior has a positive relationship with heat demands, and a negative relationship with cold demands. Aggressive behavior is also positively correlated with sunlight and altitude, and negatively correlated with coastline vicinity. Forest, coastline vicinity, and rainfall moderated the effect of thermal demands on aggressive behavior. In societies with more forests, with more rainfall, and closer to coastline, the negative effects of cold demands on aggressive behavior are stronger. (shrink)

Principles of bcnciiccnce require us to promote the good. If we believe that a plausible mom] conception will contain some such principle, we must address the issue of the demands it imposes on agents.

In this paper I su ggest that we 100k at the demands 0f beneficencc in a different way; 0ur concern should not just be with the extent of (...) the demands faced by individual agents.

This View about beneiicence and compliance is supported by a particular conception 0f beneiiccnce.

Findings suggest a positive impact of bilingualism on cognition, including the later onset of dementia. However, it is not clear to what extent these effects are influenced by variations in attentional control demands in response to specific task requirements. In this study, 20 bilingual and 20 monolingual older adults performed a task-switching task under explicit task-cuing vs. memory-based switching conditions. In the cued condition, task switches occurred in random order and a visual cue signaled the next task to be performed. (...) In the memory-based condition, the task alternated after every second trial in a predictable sequence without presenting a cue. The performance of bilinguals did not vary across experimental conditions, whereas monolinguals experienced a pronounced increase in response latencies and error rates in the cued condition. Both groups produced similar switch costs and mixing costs, but bilinguals produced them with lower response latencies. The cognitive benefits of bilingualism seem not to apply to executive functions per se but to affect specific cognitive processes that involve task-relevant context processing. The present results suggest that lifelong bilingualism could promote in older adults a flexible adjustment to environmental cues, but only with increased task demands. However, due to the small sample size, the results should be interpreted with caution. (shrink)

Proponents of double‐effect reasoning — relying in part on a distinction between intention and foresight — assert that it is worse intentionally to cause harm than to cause harm with foresight but without intention. They hold, for example, that terror bombing is worse than tactical bombing in so far as terror bombing is the intentional harming of non‐combatants while tactical bombing is not. In articulating the ethical relevance of the intended/foreseen distinction, advocates of double effect employ the Kantian (...) end‐not‐means principle. Jonathan Bennett has recently argued that this principle cannot ground the ethical relevance of the intended/foreseen distinction. He holds that the principle demands that one benefit others while double effect deals with acts that do not benefit others. Thus, he maintains, the intended/foreseen distinction does not have ethical import and double effect is not tenable. I argue for a reading of the end‐not‐means principle that grounds the ethical relevance of both the intended/foreseen distinction and double effect. (shrink)

Most studies on tourism destination competitiveness examined the direct relationships of destination attributes and destination competitiveness. Few studies explored the intervening mechanisms between destination attributes and competitiveness. This study selected cities above the “alpha” level in the Globalization and World Cities Research Network rankings as samples to examine the relationship between local demand and urban tourism competitiveness mediated by the quality of place. Results showed that the relationship between urban wealth and tourist arrivals was completely mediated by the quality (...) of place, while the mediating effect was not significant in the relationship between urban wealth and per capita tourism spending, though per capita tourism spending was directly and positively associated with urban wealth. In other words, richer cities had a higher quality of place, and a higher quality of place attracted more tourists but did not increase tourism per capita spending. Furthermore, the study found that there were two opposite influence paths of city size on urban tourism competitiveness. Although urban tourism competitiveness was directly and positively affected by population, the population had a significant negative effect on urban tourism competitiveness mediated by the quality of place. Through the quality of place, we can be aware of the indirect negative effect suppressed by the direct positive effect. This study revealed that the quality of place helped to better understand the competitiveness of urban tourism. (shrink)

Based on the challenge-hindrance stressor model, this study explored the mechanism of how challenge/hindrance demands affect cognitive wellbeing on a daily basis. Specifically, we examined the mediating effect of work–family enrichment on the relationship between challenge/hindrance demands and cognitive wellbeing. In addition, we tested the moderating effect of overqualification on the relationship between challenge/hindrance demands and work–family enrichment on a daily basis. Finally, we examined the moderated mediation effect of perceived overqualification in a multilevel model. To capture (...) changes in work–family enrichment and cognitive wellbeing that individuals perceived daily, the experience sampling method was adopted to test our theoretical models. A total of 99 participants from China were involved in this investigation. The results showed that daily challenge demands had a significant positive effect on daily cognitive wellbeing, and daily hindrance demands had a significant negative effect on wellbeing. In addition, daily work–family enrichment mediated the positive relationship between daily challenge demands and daily cognitive wellbeing. Moreover, perceived overqualification moderated the relationship between daily challenge demands and daily cognitive wellbeing in the multilevel model. Finally, a significant moderated mediating effect of this overqualification on the indirect effect of daily work–family enrichment on the relationship between daily challenge demands and daily cognitive wellbeing was observed.

Can ownership status influence probability judgements under condition of uncertainty? In three experiments, we presented our participants with a recording of a real horse race. We endowed half of our sample with a wager on a single horse to win the race, and the other half with money to spend to acquire the same wager. Across three large studies, we found the endowment effect – owners demanded significantly more for the wager than buyers were willing to pay to acquire (...) it. However, we also found that probability estimates of each horse winning the race did not differ between owners and non-owners of the betting slip. Our results demonstrate that distorted perception of probability is unlikely to be a mechanism explaining the endowment effect. (shrink)

Food safety has become a major development challenge and a key influence on the strategic behavior of food companies. The study seeks to analyze the effect of perceived institutional pressures on the governance of food safety and the effect this may have on food safety performance in emerging food supply chains. The research develops a conceptual framework that links perceived institutional pressures, degree of food manufacturer-supplier relationships, food safety practices, and food safety output. The hypothesized relationships were tested (...) in the Middle Eastern context, where food safety concerns are rising. Accordingly, a survey was carried out to collect data from food quality/safety managers representing 94 food processors across Lebanon. The study finds that perceived institutional pressures have a direct and strong effect on the degree of integration in the agro-food supply chain, and such an integration, in turn, increases the intensity of food safety practices and food safety performance. However, in the absence of strong manufacturer-supplier relationships, perceived institutional pressures do not lead to improved food safety performance. The study suggests that long-term food manufacturer-supplier relationship is necessary if agro-food chain actors are to respond to established regulatory demands, industry practices, and social norms.
