This study investigated the concept of individual differences (IDs) in the use of metacognitive strategies (planning, problem-solving, monitoring, and evaluating) and its relationship with task demand and learner performance within Kormos’ Bilingual Speech Production Model from the lens of Chinese English-as-foreign-language (EFL) learners in the context of integrated L2 speaking assessment. To measure metacognitive strategies, we administered an inventory on 134 Chinese EFL learners after they completed four integrated L2 speaking assessment tasks. Descriptive analysis and multiple linear regression were (...) adopted for data analysis, and results show that: (a) IDs displayed variance in Chinese EFL learners’ metacognitive strategy use; (b) among the four metacognitive strategies under investigation, problem-solving was reported to be used the most frequently in sharp contrast to monitoring, which had the lowest frequency; (c) metacognitive strategies worked interactively, responding to task demands involved in the four integrated L2 speaking assessment tasks; and (d) Chinese EFL learners’ use of metacognitive strategies, in individual and interactive working modes, had no relationship with their speaking performance. These results are expected to present some insights into the role of IDs in metacognitive strategy use during L2 speech production under assessment conditions, which will add robust evidence to the existing literature on L2 speaking, in particular on metacognitive strategy use in L2 speaking assessment. In the meantime, the findings will provide some empirical validation support for Kormos’ model, which will further provide some implications for L2 speaking instruction and L2 assessment. (shrink)

A debate is a public dispute that follows certain rules. The goal of a debate is not the solution of a problem as in a discussion, but to point out positions. In a debate, not only arguments, but also polemics and the courage to take a stand are essential. Besides certain rules that are accepted by all participants, a debate needs a so-called debate culture in order to be productive. Christian Demand and Ekkehard Knörer lead a debate on the (...) establishment of this concept in the 1980s and develop theses for its alleged disappearance caused by the acceleration of debates under the conditions of “new media.”.

Can morality be so demanding that we have reason not to follow its dictates? According to many, it can, if that morality is a consequentialist one. We take the plausibility and coherence of this objection – the Demandingness Objection – as a given and are also not concerned with finding the best response to the Objection. Instead, our main aim is to explicate the intuitive background of the Objection and to see how this background could be investigated. This double aim (...) leads to different albeit connected threads of inquiry. We first outline the Objection, its different forms and how intuition figures in them. After this, we move on to consider the ongoing debate about the use of intuitions in (moral) philosophy with a focus on two challenges: what intuitions are and how we can detect them. To answer these challenges, we propose an account according to which moral intuitions are seemings that are characterized by being non-inferential, spontaneous, non-doxastic, phenomenologically distinctive, non-sensory, intrinsically motivating, and stable. Armed with these seven “markers” of moral intuition, we put a forward a complex experimental methodology and raise and respond to possible problems with it. (shrink)

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess (...) problem tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

Mindfulness training is often promoted as a method to train cognitive functions and has shown such effects in previous studies. However, many conventional mindfulness exercises for beginners require cognitive effort, which may be prohibitive for some, particularly for people who have more pronounced cognitive problems to begin with. An alternative mindfulness-based approach, called restoration skills training, draws on a restorative natural practice setting to help regulate attention effortlessly and promote meditative states during exercises. Previous research has shown that a 5-week (...) ReST course requires less effort and is attended by higher compliance with practice recommendations than a conventional mindfulness course, without compromising long-term outcomes. Here, we compare ReST and a formally matched conventional mindfulness course regarding the role that initial individual differences in cognitive functioning play in determining practice compliance and long-term improvements in dispositional mindfulness and cognitive functioning. In line with expectations, ReST participants who had more pronounced cognitive problems to begin with practiced more during the course, which in turn explained much of their improvement in dispositional mindfulness and cognitive functioning. In contrast, initial cognitive functioning did not explain practice and improvement in the conventional mindfulness course. The results provide further support for the potential utility of ReST as a low-effort method for enhancing cognitive functioning among people who would struggle with the demands of conventional mindfulness training. With careful integration of mindfulness practices with a restorative natural setting, these people can develop mindfulness and self-regulation capabilities without relying on effortful training.

If the traditional problem of demandingness is that a theory demands too much of all agents, for example by asking them to maximize utility in every decision, then we should ask whether there is a related problem of “differential demandingness”, when a theory places vastly different demands on different agents. I argue that even according to common-sense morality, the demands faced by particular agents depend on a variety of contingent factors. These include the (...) general circumstances, the compliance of others, the available resources, the agent’s relevant relationships, the agent’s psychological constitution, and the agent’s knowledge. Some agents, for instance, find themselves in a “sacrifice hazard”: a situation where morality calls for a huge unforeseen sacrifice. I argue that if moral demands are differential, it is harder than one might think to assess a theory’s general level of demandingness in the abstract. (shrink)

Part-time work schedules are a popular option for many women struggling to reconcile the competing demands of employment and motherhood. They are controversial among feminists because they are associated with job penalties that promote gender inequality. Previous research on this topic has focused on issues confronting women workers in professional and managerial jobs. In this article, we compare and contrast the experiences of women in professional and secondary part-time jobs, drawing on 60 in-depth interviews with mothers working in such (...) “good” and “bad” jobs. We find that mothers at the top and at the bottom of the employment hierarchy face unique disadvantages from their part-time employment to which they respond in different ways. Yet in both instances, mothers assume responsibility for their “choices,” which absolves organizations of blame for exploitation and discrimination against part-time workers. We suggest alternative possibilities for the organization of work in the conclusion. (shrink)

Energy has an ambivalent status in social theory, variously figuring as a driver or an outcome of social and institutional change, or as something that is woven into the fabric of society itself. In this article the authors consider the underlying models on which different approaches depend. One common strategy is to view energy as a resource base, the management and organization of which depends on various intersecting systems: political, economic and technological. This is not the only route to (...) take. The authors develop an alternative approach, viewing energy supply and energy demand as part of the ongoing reproduction of bundles and complexes of social practice. In articulating and comparing these two positions they show how social-theoretical commitments influence the ways in which problems like those of reducing carbon emissions are framed and addressed. Whereas theories of practice highlight basic questions about what energy is for, these issues are routinely and perhaps necessarily obscured by those who see energy as an abstract resource that structures or that is structured by a range of interlocking social systems.

We examined how children's strategy choices in solving complex subtraction problems are related to grade and to variations in problem complexity. In two studies, third- and fifth-grade children (N≈160 each study) solved multi-digit subtraction problems (e.g., 34–18) and described their solution strategies. In the first experiment, strategy selection was investigated by means of a free-choice paradigm, whereas in the second study a discrete-choice approach was implemented. In both experiments, analyses of strategy repertoire indicated that third-grade children were more likely (...) to report less-efficient strategies (i.e., counting) and relied more on the right-to-left solution algorithm compared to fifth-grade children who more often used efficient memory-based retrieval and conceptually-based left-to-right (i.e., decomposition) strategies. Nevertheless, all strategies were reported or selected by both older and younger children and strategy use varied with problem complexity and presentation format for both age groups. These results supported the overlapping waves model of strategy development and provide detailed information about patterns of strategy choice on complex subtraction problems. (shrink)

The current study examines similarity or disparity of a frontally mediated physiological response of mental effort among multiple executive functioning tasks between children and adults. Task performance and phasic heart rate variability (HRV) were recorded in children (6 to 10 years old) and adults in an examination of age differences in executive functioning skills during periods of increased demand. Executive load levels were varied by increasing the difficulty levels of three executive functioning tasks: inhibition (IN), working memory (WM), and planning/ (...) class='Hi'>problem solving (PL). Behavioral performance decreased in all tasks with increased executive demand in both children and adults. Adults’ phasic high frequency HRV was suppressed during the management of increased IN and WM load. Children’s phasic HRV was suppressed during the management of moderate WM load. HRV was not suppressed during either children’s or adults’ increasing load during the PL task. High frequency phasic HRV may be most sensitive to executive function tasks that have a time-response pressure, and simply requiring performance on a self-paced task requiring frontal lobe activation may not be enough to generate HRV responsitivity to increasing demand.

We examined whether positive and negative affect motivates verbal and spatial working memory processes, respectively, which have implications for the expenditure of mental effort. We argue that when emotion promotes cognitive tendencies that are goal incompatible with task demands, greater cognitive effort is required to perform well. We sought to investigate whether this increase in cognitive effort impairs behavioural control over a broad domain of self-control tasks. Moreover, we predicted that individuals with higher behavioural inhibition system (BIS) sensitivities would (...) report more negative affect within the goal incompatible conditions because such individuals report higher negative affect during cognitive challenge. Positive or negative affective states were induced followed by completing a verbal or spatial 2-back working memory task. All participants then completed one of three self-control tasks. Overall, we observed that conditions of emotion and working memory incompatibility (positive/spatial and negative/verbal) performed worse on the self-control tasks, and within the incompatible conditions individuals with higher BIS sensitivities reported more negative affect at the end of the study. The combination of findings suggests that emotion and working memory compatibility reduces cognitive effort and impairs behavioural control. (shrink)

Sensitivity to others’ emotional signals is an important factor for social interaction. While many studies of emotional reactivity focus on facial emotional expressions, signals such as pupil dilation which can indicate arousal, may also affect observers. For example, observers’ pupils dilate when viewing someone with dilated pupils, so-called pupillary contagion. Yet it is unclear how pupil size and emotional expression interact as signals. Further, examining individual differences in emotional reactivity to others can shed light on its mechanisms and potential outcomes. (...) In the current study, adults’ (N = 453) pupil size was assessed while they viewed images of the eye region of individuals varying in emotional expression (neutral, happy, sad, fearful, angry) and pupil size (large, medium, small). Participants showed pupillary contagion regardless of the emotional expression. Individual differences in demographics (gender, age, socioeconomic status) and psychosocial factors (anxiety, depression, sleep problems) were also examined, yet the only factor related to pupillary contagion was socioeconomic status, with higher socioeconomic status predicting less pupillary contagion for emotionally-neutral stimuli. The results suggest that while pupillary contagion is a robust phenomenon, it can vary meaningfully across individuals. (shrink)

Drawing on John Dewey's discussion of habit in Human Nature and Conduct and Simone de Beauvoir's discussion of the “adventurer” in The Ethics of Ambiguity, I argue that while some of our relations with things and people may very well be instrumental, many take a different form in which it is our very setting, and not merely our attainment, of ends that is at stake. Moreover, the fullest realization of our freedom requires us to recognize not only that this (...) different form of relation, which is cooperative rather than controlling, exists but also that it is constitutive of, rather than in opposition to, our freedom. I conclude by briefly examining how our honest acknowledgment of a kind of powerlessness inherent to our powers, to our freedom, might change the way we interact with other things and other people.

Navigating to goal locations in a known environment (wayfinding) can be accomplished by different strategies, notably by taking habitual, well-learned routes (response strategy) or by inferring novel paths, such as shortcuts, from spatial knowledge of the environment's layout (place strategy). Human and animal neuroscience studies reveal that these strategies reflect different brain systems, with response strategies relying more on activation of the striatum and place strategies associated with activation of the hippocampus. In addition to individual differences in strategy, (...) recent behavioral studies show sex differences such that men use place strategies more than women, and age differences such that older adults use more response strategies than younger adults. This paper takes a comprehensive multilevel approach to understanding these differences, characterizing wayfinding as a complex information processing task. This analysis reveals factors that affect navigation strategy, including availability of the relevant type of environmental knowledge, momentary access to this knowledge, trade-offs between physical and mental effort in different navigation contexts, and risk taking. We consider how strategies are influenced by the computational demands of a navigation task and by factors that affect the neural circuits underlying navigation. We also discuss limitations of laboratory studies to date and outline priorities for future research, including relating wayfinding strategies to independent measures of spatial knowledge, and studying wayfinding strategies in naturalistic environments.

instead he argues for a conditional: "if there is such a thing as narrow content, it is holistic," where holism is taken to be "the doctrine that any _substantial_ difference in W-beliefs, whether between two people or between one person at two times, requires a difference in the meaning or content of W" (153, 152).

An influential objection to act-consequentialism holds that the theory is unduly demanding. This paper is an attempt to approach this critique of act-consequentialism – the Overdemandingness Objection – from a different, so far undiscussed, angle. First, the paper argues that the most convincing form of the Objection claims that consequentialism is overdemanding because it requires us, with decisive force, to do things that, intuitively, we do not have decisive reason to perform. Second, in order to investigate the existence of (...) the intuition, the paper reports empirical evidence of how people see the normative significance of consequentialist requirements.. In a scenario study that recruited a sample which is representative of the German population in key characteristics, it finds that there is no widely shared intuition as to the excessive demandingness of consequentialist requirements, although people do find higher demands less reasonable. This is true irrespective of people’s level of formal education despite the fact that lower levels of formal education are associated with an increased likelihood of having intuitions that are consistent with the Objection. Apart from contributing in this way to the debate concerning the Overdemandingness Objection, the paper also more directly speaks to the basic discussion concerning the status and role of intuitions in moral philosophy. It discusses methodological questions relevant to the role of intuitions and ends with proposing an improved methodology to investigate intuitions that connects them to emotions in a particular way and also proposes a role for virtue.

Human fluid intelligence is closely linked to the sequential solving of complex problems. It has been associated with a distributed cognitive control or multiple-demand network, comprising regions of lateral frontal, insular, dorsomedial frontal, and parietal cortex. Previous neuroimaging research suggests that the MD network may orchestrate the allocation of attentional resources to individual parts of a complex task: in a complex target detection task with multiple independent rules, applied one at a time, reduced response to rule-critical events across the MD (...) network in lower fluid intelligence was observed. This was in particular the case with increasing task complexity, and was accompanied by impairment in performance. Here, we examined the early spatiotemporal neural dynamics of this process in electroencephalography source analyses using a similar task paradigm. Levels of fluid intelligence specifically predicted early neural responses in a left inferiorparietal MD region around 200–300 ms post stimulus onset. Evoked source amplitudes in left parietal cortex within this early time window also correlated with behavioural performance measures. Like in previous research, we observed impaired performance in lower fluid intelligence with increasing number of task rules. This links fluid intelligence to a process of attentional focus on those parts of a task that are most critical for the current behaviour. Within the MD system, our time re-resolved measures suggest that the left parietal cortex specifically impacts on early processes of attentional focus on task critical features. This is novel evidence on the neurocognitive correlates of fluid intelligence suggesting that individual differences are critically linked to an early process of attentional focus on task-relevant information, which is supported by left parietal MD regions.

We report data from an experiment using stimuli designed to differ in their availability for processing by the dorsal visual pathway, but which were equivalent in tasks mediated by the ventral pathway. When movements are made to these stimuli as targets, there are clear effects early in the movement. These effects appear at odds with the planning–control model of Glover.

I offer two objections to luck egalitarianism. The no-adequate-account objection takes note of the egalitarian insistence that the disvalue of inequality is only one of a plurality of values or disvalues that needs to be considered in arriving at a judgment about the ranking of alternative distributions of welfare. This turn to pluralism places a reasonable demand upon luck egalitarianism to provide an account of how the different sorts of values or disvalues that are supposed to attach to available (...) distributions of welfare are to be aggregated or weighed against one another in that ranking procedure. I contend that the prospects for developing such an account are dim and that some salient responses to this objection misfire. The churlishness-envy objection against luck egalitarianism is that this doctrine countenances envy directed toward the faultless good fortune of others. This objection places a reasonable demand on luck egalitarians to formulate a version of their doctrine that does not underwrite envious responses toward those who gain through brute good luck. I contend that the most auspicious path toward satisfying the demand not to underwrite churlish envy advances a luck egalitarianism that asymmetrically affirms the badness of arbitrary disadvantage rather than the badness of both arbitrary disadvantage and arbitrary advantage. Since this is the strategy pursued in Shlomi Segall’s Why Inequality Matters, I offer critiques of Segall’s initial and revised versions of asymmetrical egalitarianism in support of my conclusion that luck egalitarianism seems unable to rebut or sidestep the churlishness-envy objection. I conclude that luck egalitarianism seems unable to satisfy either of the two reasonable demands upon it that I raise. (shrink)

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of (...) each referee during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

In contrast to multicultural theory, which in discussions of respect for difference has primarily focussed on the state as the agent of respect, multicultural policy has instead tended to focus on citizens themselves as the potential agents of this sort of respect. This article examines the plausibility of this type of respect (which is advocated by some theorists too), and argues that is not a reasonable or necessary demand. While there are several different ways of understanding respect — most (...) of which focus on respecting persons — none seem capable of doing the work required for it to enable either the adequate or reasonable accommodation of diversity in a liberal society. More specifically, I use Darwall's influential distinction between appraisal and recognition respect — the latter in a broad non-moralised sense — to make my case. While appraisal respect for difference may be theoretically easy to dismiss, it is not uncommon in multicultural policy. On the other hand, recognition respect — which is more behavioural than attitudinal — may appear a more plausible candidate. Yet it too remains overly demanding for individual citizens, especially, and most importantly, in difficult cases. I conclude that tolerance of difference (coming out of respect for citizenship) is a more appropriate demand on the individual. (shrink)

By comparing alternative evolutionary models, the International Sexuality Description Project marks the transition of evolutionary psychology to the next level of scientific maturation. The lack of final conclusions might partly be a result of the composition of the Sociosexual Orientation Inventory and the sampled populations. Our own data suggest that correcting for both gives further support to the strategic pluralism model.

This paper explores the effect of different types of incubation task (visual, numerical and verbal) with various levels of attentional focus and cognitive effort (non-demanding, low-demanding and high-demanding) on the resolution of insight problems. The most effective was found to be the low-demanding task (regardless of its nature), which although requiring attentional focus, leaves resources available for the unconscious analytical restructuring process, obtaining a high percentage of success in solving the problem shortly after completion of the incubation task. (...) Overall findings support the hypothesis of Unconscious Analytic Thought (UAT), according to which the restructuring required in insight problem solving implies a covert thinking process that includes a relevant, analytic and goal-oriented search. The findings are discussed in the light of UAT and are compared with the main theories of insight in problem solving. (shrink)

Research in recent years suggests that fairness concerns could mitigate hold-up problems. In this study, we report theoretical analysis and experimental evidence on an opposite possibility: that fairness concerns could also induce hold-up problems. In our setup, hold-up problems will not occur with purely self-interested agents, but theoretically could be induced by demand for distributional fairness among agents without sufficiently strong counteracting factors such as intention-based reciprocity. We observe a widespread occurrence of hold-up in our experiment. Relationship-specific investments occurred less (...) than half of the time, resulting in significant inefficiencies. Moreover, whenever a relationship-specific investment was made: (a) it was typically not reciprocated by the partner; (b) nor did the investor’s offers at the bargaining stage exhibit expectations for reciprocity. Consequently, the partner extracted all the additional expected payoff from relationship-specific investments. Further experimentation suggested that our results were driven by a fundamental lack of intention-based reciprocity in fairness concerns, rather than self-serving bias. (shrink)

As research on mind wandering has accelerated, the construct’s defining features have expanded and researchers have begun to examine different dimensions of mind wandering. Recently, Christoff and colleagues have argued for the importance of investigating a hitherto neglected variety of mind wandering: “unconstrained thought,” or, thought that is relatively unguided by executive-control processes. To date, with only a handful of studies investigating unconstrained thought, little is known about this intriguing type of mind wandering. Across two experiments, we examined, for (...) the first time, whether changes in task demand influence rates of constrained versus unconstrained thoughts. In both experiments, participants completed either an easy (0-back) or hard (2-back) task and responded to intermittently presented thought probes that gauged thought constraint throughout the task. In Experiment 1, we found that participants completing the easy task engaged in unconstrained thoughts more frequently than those completing the difficult task. In Experiment 2, we replicated this result and further demonstrated manipulations of unconstrained thought while also measuring task-relatedness (a common dimension of mind wandering). Finally, exploratory analyses showed associations between constrained thought and age, verbal intelligence, and an assessment of flow (‘deep effortless concentration’), thereby adding further evidence to indicate a dissociation between task-relatedness and constraint. We discuss the methodological and theoretical applications of our findings to the burgeoning field of research on unconstrained thought. (shrink)

This article explores staff work patterns in an Australian residential aged care facility and the implications for high‐quality care. Rarely available minute by minute, time and motion, and ethnographic data demonstrate that nurses and care staff engage in high degrees of multitasking and mental switching between residents. Mental switching occurs up to 18 times per hour (every 3 min); multitasking occurs on average for 37 min/h. Labor process theory is used to examine these outcomes and to explore the concepts of (...) high demand and high commitment as core components of work intensification. These conditions of work result in high levels of cognitive burden and stress on staff in managing the multitasking and mental switching, exacerbated by lack of knowledge about residents associated with labor force casualization. These new interpretations of data in relation to mental and manual labor can contribute to understanding, and, therefore, problem solving, in the aged care sector. (shrink)

There are various egalitarian moral doctrines. They differ in the requirements they impose on institutions and social practices and on individual conduct. This essay sketches two versions of egalitarian social justice and claims that the requirements they impose should strike us as reasonable, all things considered. One is welfarist egalitarianism, a cousin of classical utilitarianism. This version requires bringing about good quality lives for people and fair (equal) distribution of this good across persons. A notable feature of welfarist egalitarianism is (...) that it accommodates the seemingly antiegalitarian claim that it does not matter in itself how one person’s condition compares to that of another, so a fortiori it does not matter in itself whether or not one person’s condition compares to that of others in the one particular way of being equal. The other version is relational or freedom-oriented egalitarianism, which holds that we should above all ensure that people are free to live as they choose and relate as equals, without social hierarchy. In the latter half of the twentieth century, John Rawls developed a powerful articulation of relational egalitarian justice. This essay sketches the two rival egalitarianisms with a view to showing their respective moral attractiveness and to suggesting that the welfarist version has greater moral attraction. (shrink)

BackgroundThe Ethiopian law on abortion was liberalized in 2005. However, as a strongly religious country, the new law has remained controversial from the outset. Many abortion providers have religious allegiances, which begs the question how to negotiate the conflicting demands of their jobs and their commitment to their patients on the one hand, and their religious convictions and moral values on the other.MethodA qualitative study based on in-depth interviews with 30 healthcare professionals involved in abortion services in either private/non-governmental (...) clinics or in public hospitals in Addis Ababa, Ethiopia. Transcripts were analyzed using systematic text condensation, a qualitative analysis framework.ResultsFor the participants, religious norms and the view that the early fetus has a moral right to life count against providing abortion; while the interests and needs of the pregnant woman supports providing abortion services. The professionals weighed these value considerations differently and reached different conclusions. One group appears to have experienced genuine conflicts of conscience, while another group attempted to reconcile religious norms and values with their work, especially through framing provision of abortion as helping and preventing harm and suffering. The professionals handle this moral balancing act on their own. In general, participants working in the private sector reported less moral dilemma with abortion than did their colleagues from public hospitals.ConclusionsThis study highlights the difficulties in reconciling tensions between religious convictions and moral norms and values, and professional duties. Such insights might inform guidelines and healthcare ethics education. (shrink)

Trolley problems have been used in the development of moral theory and the psychological study of moral judgments and behavior. Most of this research has focused on people from the West, with implicit assumptions that moral intuitions should generalize and that moral psychology is universal. However, cultural differences may be associated with differences in moral judgments and behavior. We operationalized a trolley problem in the laboratory, with economic incentives and real-life consequences, and compared British and Chinese samples on moral (...) behavior and judgment. We found that Chinese participants were less willing to sacrifice one person to save five others, and less likely to consider such an action to be right. In a second study using three scenarios, including the standard scenario where lives are threatened by an on-coming train, fewer Chinese than British participants were willing to take action and sacrifice one to save five, and this cultural difference was more pronounced when the consequences were less severe than death.

In this paper, we consider three different search strategies for a cut-free sequent system formalizing orthologic, and estimate the respective search spaces. Applying backward search, there are classes of formulae for which both the minimal proof length and the search space are exponential.

Using a forward strategy, the potential search space becomes polynomial yielding a polynomial decision procedure for orthologic and the (...) word problem for free ortholattices. (shrink)

Despite the increasing interest in clinical ethics, ethics consultation as a professional service is still rare in Europe. In this paper I refer to examples in the United States. In Germany, university hospitals and medical faculties are still hesitant about establishing yet another “committee”. One of the reasons for this hesitation lies in the ignorance that exists here about how to provide medical ethics services; another reason is that medical ethics itself is not yet institutionalised at many German universities. The (...) most important obstacle, however, may be that medical ethics has not yet demonstrated its relevance to the needs of those caring for patients. The Centre for Ethics and Law, Freiburg, has therefore taken a different approach from that offered elsewhere: clinical ethics consultation is offered on demand, the consultation being available to clinician(s) in different forms. This paper describes our experiences with this approach; practical issues are illustrated by a case study. (shrink)

The central problem in Geary's theory is how differences are conceptualized. Recent research has shown that between-sex differences on certain tasks are a consequence of averaging within sex differences.

Bagging ), boosting and extreme gradient boosting regression ), and stacking are employed as ensemble models. Different machine learning approaches, including support vector regression, extreme learning machine, and multilayer perceptron neural network, are adopted as reference models. In order to maximize the determination coefficient value and reduce the root mean square error, hyperparameters are set (...) using the grid search method. Using a steel industry dataset, all tests are carried out under identical experimental conditions. In this context, STACK1 and STACK2 models provided better performance than other models. The highest accuracies of R2 of 0.97 and 0.97 are obtained using STACK1 and STACK2, respectively. Moreover, the rank according to performances is STACK1, STACK2, XGBR, GBR, RFR, MLP, ELM, and SVR. As it improves the performance of models and reduces the risk of decision-making, the ensemble method can be used to forecast the demand in a steel industry one month ahead. (shrink)

ABSTRACTBy means of critical reflection on the current situation of Chinese philosophy, this article aims to clarify two different approaches to philosophy. One is for scholars to focus on original texts and thought tradition, concerned with interpretation and inheritance; even in this way, scholars can achieve theoretical innovation through creative interpretation. The other is for researchers to face up questions from academics and from reality, and mainly to do theoretical creation in philosophy on a profound theoretical background, strictly following (...) academic norms and standards. For contemporary Chinese philosophy, the two approaches are indispensable, but the serious problem is that the first approach absolutely is dominant, but the second is too weak. The correct choice of Chinese philosophy should be to let hundreds of flower bloom, to let different approaches compete with each other, and to cooperatively establish the prosperity of contemporary Chinese philosophy.

Murphy’s book is concerned with what he calls the “puzzle of beneficence”: that, while there are many moral issues on which people tend to agree, there is not only no consensus about the extent of the obligation to promote the wellbeing of strangers, but in fact a contentedness about the uncertainty of our obligation in this regard. Although there are some famous philosophical suggestions concerning the reasons for this puzzle, Murphy claims that what is most important is our tendency to (...) view beneficence in terms of collective responsibility. The question of collective responsibility raises particularly the issue of “non-ideal theory”—“what a given person is required to do in circumstances where at least some others are not doing what they are required to do.” Murphy’s chief aims are first to explain the absurdity of the demands of the utilitarians’ “optimizing principle of beneficence”—that we must keep benefiting others until the point where further efforts would burden us as much as they would help the others—and to suggest instead a more plausible principle of beneficence. His suggestion—a “collective principle of beneficence”— involves a “compliance condition”: that the demands on a complying person should not exceed what they would be under full compliance with the principle. Murphy argues at some length that the apparent absurdity of the optimizing principle of beneficence is due not to a problem of “overdemandingness” in general, but rather to a failure to take into consideration nonideal situations where there is only partial compliance. Although his more technical formulations of the correcting “collective” principle of beneficence are admittedly “cumbersome,” the “basic idea,” as he represents it, is that “a person need never sacrifice so much that he would end up less well-off than he would be under full compliance from now on, but within that constraint he must do as much good as possible”. The argument for this position has some intuitive appeal when it is applied, for example, in situations where the fairness of imposing extreme demands is clearly in question. Murphy uses the following example: if everyone else including me would die from a nuclear explosion that I can prevent by exposing myself to a lethal does of radiation, I am required under his principle to do so. Murphy has to give a more complicated response to a less intuitively appealing apparent consequence of his principle—that, when used to consider issues like poverty, it would not seem to require many people in our actual world to sacrifice. He admits that his principle cannot be a stand-alone basis for ethics—for one thing, the concern of his argument is specifically with the difficulties of principles of beneficence, which make a requirement on us that it would be wrong not to perform; voluntary or supererogatory acts are thereby left aside. There are, as well, some familiar further problems which may in the end, however, be no more difficult for Murphy’s principle than for the principle of optimizing beneficence.—Allen Speight, Boston University.

Climate change appears to be a classic aggregation problem, in which billions of individuals perform actions none of which seem to be morally wrong taken in isolation, and yet which combine to drive the global concentration of greenhouse gases (GHGs) ever higher toward environmental (and humanitarian) catastrophe. When an individual can choose between actions that will emit differing amounts of GHGs―such as to choose a vegan rather than carnivorous meal, to ride a bike to work rather than drive a (...) car, or to take a reusable bag to the supermarket rather than send another plastic bag to landfill―does she have any reason to choose the lower-emitting actions? In this chapter I'll reject the claim that individuals don't make a difference when it comes to climate change. I first discuss making a difference with every action, as a way of getting clearer about how individuals' actions impact causally on the harms resulting from climate change, making a distinction so far overlooked in the climate ethics discussion between 'macro' thresholds like ice-cap melt, and 'micro' thresholds like severe weather events. I set aside making a difference with every action as implausible, and then move on to discuss both low probability of major difference, and high probability of minor difference. I argue that both of these are plausible characterizations of individuals' causal contributions to climate change. I conclude by noting some policy implications of having (probabilistic) individual difference-making back in play. (shrink)

Keynes's theory of interest is central to his broader argument. However, short‐run policy, which takes the so‐called normal rate of interest as given and aims at affecting the prevailing rate, must be distinguished from long‐run reform, which aims at changing the normal rate. The low demand that Keynes associated with high interest was believed to be inherent in a decentralized, consumption‐oriented economy. Consequently, he advocated reform in the direction of central control. Despite his “moral and philosophical” agreement with Hayek's Road (...) to Serfdom, Keynes differed fundamentally from Hayek in terms of their contrasting perceptions of the market's shortcomings and their judgments about the government's potential for improving the economy's performance.

Ministers of religion have a unique occupation with designated job demands and incongruous resources at their disposal. Literature indicates that stressors within the work environment are significant predictors of work-nonwork interference. Ministers play a key role within society and provide support for individuals on multiple levels. However, limited studies are found in South Africa focussing on ministers' job characteristics related to work-nonwork interference, and how ministers cope. The main objective of this study was to investigate job demands and (...) job resources as significant predictors of work-nonwork interference amongst ministers of religion, and to identify which coping strategies are most significant for ministers in dealing with work-nonwork interference. A cross-sectional survey design was used amongst ministers working in the three sister churches. Various instruments were administered to measure job characteristics, work-nonwork interference and coping strategies empirically. Statistical analyses included descriptive statistics, product-moment correlations and multiple regression analyses. Results indicated that for ministers different job demands and job resources significantly predicted work-parent, work-home and work-religion/spirituality interference. Results indicated turning to religion as the only significant coping strategy used by ministers to deal with work-parent interference and work-religion interference. Ministers of religion are continually exposed to increasing job demands and a lack of job resources, and therefore experience work-nonwork interference. Nevertheless, the ministers apparently cope by using the strategy best related to their profession, turning to religion/spirituality. Turning to religion/spirituality seems to be the most effective in dealing with work-nonwork interference. (shrink)

For nearly 70 years, studies have shown large sex differences in human mate selection preferences. However, most of the studies were restricted to a limited set of mate selection criteria and to college students, and neglecting relationship status. In this study, 21,245 heterosexual participants between 18 and 65 years of age (mean age 41) who at the time were not involved in a close relationship rated the importance of 82 mate selection criteria adapted from previous studies, reported age ranges for (...) the oldest and youngest partner that they would find acceptable, and responded to 10 yes/no questions about a potential marriage partner. For nearly all mate selection criteria, women were found to be the more demanding sex, although men placed consistently more value on the physical attractiveness of a potential partner than women. Also, the effects of the participants’ age and level of education were nearly negligible. These results demonstrate the robustness of sex differences in mate selection criteria across a substantial age range. (shrink)

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the (...) only necessary property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

Spatial visualization as a key variable in sex-related differences in mathematical problem solving and spatial aspects of geometry is traced to the 1960s. More recent relevant data are presented. The variability debate is traced to the latter part of the nineteenth century and an explanation for it is suggested. An idea is presented for further research to clarify sex-related brain laterality differences in solving spatial problems.
