The Internal Suicide Debate Hypothesis: Exploring the Life versus Death Struggle

Researchers and theorists (e.g., Shneidman, Stengel, Kovacs, and Beck) hyothesized that suicidal people engage in an internal debate, or struggle, over whether to live or die, but few studies have tested its tenability. This study introduces direct assessment of a suicidal debate, revealing new aspects of suicidal ideation. Results, from an online survey (N = 1,016), showed nearly all suicide‐risk respondents engaged in the debate. In addition, debate frequency accounted for 54% of the variance in suicidality scores, and showed significant associations with other indicators of suicide risk. Likely factors of the debate, reasons for living and dying, showed significant differences by suicidality, and most suicide‐risk participants reported going online for such purposes, demonstrating a behavioral component of the debate.     

The Relativistic Car: Applying Metaethics to the Debate about Self-Driving Vehicles

Almost all participants in the debate about the ethics of accidents with self-driving cars have so far assumed moral universalism. However, universalism may be philosophically more controversial than is commonly thought, and may lead to undesirable results in terms of non-moral consequences and feasibility. There thus seems to be a need to also start considering what I refer to as the “relativistic car” — a car that is programmed under the assumption that what is morally right, wrong, good, bad, etc. is determined by the moral beliefs of one’s society or culture. My investigation of this idea involves six steps. First, I explain why and how the moral universalism/relativism debate is relevant to the issue of self-driving cars. Second, I argue that there are good reasons to consider accident algorithms that assume relativism. Third, I outline how a relativistic car would be programmed to behave. Fourth, I address what advantages such a car would have, both in terms of its non-moral consequences and feasibility. Fifth, I address the relativistic car’s disadvantages. Finally, I qualify and conclude my considerations.

     

Developing Anticipation Skills in Tennis Using On-Court Instruction: Perception versus Perception and Action

On-court instruction involving either Perception–action training or Perception-only training was used to improve anticipation skill in novice tennis players. A technical instruction group acted as a control. Participants' ability to anticipate an opponent's serve was assessed pre- and posttest using established on-court measures involving frame-by-frame video analysis. The perception–action and perception-only groups significantly improved their anticipatory performance from pretest to posttest. No pretest-to-posttest differences in anticipation skill were reported for the technical instruction group. The ability to anticipate an opponent's serve can be improved through on-court instruction where the relationship between key postural cues and subsequent performance is highlighted, and both practice and feedback are provided. No significant differences were observed between the perception–action and perception-only training groups, implying that either mode of training may be effective in enhancing perceptual skill in sport.     

全局实用主义和表征主义的限度——普莱斯教授访谈

Developing Sales Force Relationalism: The Role of Distributive and Procedural Justice

Sales force justice perceptions can play an important role in the development of relational norms or relationalism; however, little research has explored the linkages between justice and the development of sales force relationalism. The relational justice model—that is, neutrality, trust, and respect—was tested with regard to direct effects on sales force perceptions of distributive and procedural justice, and in, subsequently, manager–sales force relationalism. The findings, from a sample of business-to-business salespeople, support the hypothesized relationships between the constructs in the relational model and distributive and procedural justice. Neutrality, trust, and respect significantly and positively affect both distributive and procedural justice, which directly affects the development of sales force relationalism. The results have implications for sales force management and future research endeavors.     

The Debate on Structured Debate: Toward a Unified Theory

Although structured debate has been studied extensively over the past 20 years, little theoretical understanding of the phenomenon exists. By examining the literature, this paper builds a theoretical framework for understanding structured debate by raising and exploring several key, but previously implicit theoretical issues. The paper also argues that process modeling of structured debate in group settings can afford theoretical understanding, and offers several such models and coding schemes. The implications of structured debate in real-world settings are also considered.     

The Debate: A Strategic Technique

This paper describes the work of a strategic team that came out from behind the one-way mirror. A debate among the team is enacted before the family as a strategy for change. The case of a family that refused to provide information illustrates an application of this method. The debate among the therapists represents a dilemma that is a strategically constructed isomorph of the family situation. From this position, therapists have the option of changing levels between themselves and the family, asking the family to help solve the therapists' dilemma so that they in turn can be free to help the family. The combination of the debate and the change of levels between the therapists and the family creates a therapeutic neutrality for the family. From their meta position, they observe the therapists' struggle to solve the family's problem, which is re-presented as a problem among the therapists. This perspective offers the family the choice of more adaptive solutions to their own dilemma.     

Perception and production of brief durations: beat-based versus interval-based timing

Two experiments examined whether timing of short intervals is beat- or interval-based. In Experiment 1, subjects heard a sequence of standard tones followed by 2 test tones; they compared the interval between test tones to the interval between the standards. If optimal precision required beat-based timing, performance should be best in blocks in which the interval between standard and test reliably matched the standard interval. No such effect was observed. In Experiment 2, subjects heard 2 test tones and reproduced the intertone interval by producing 2 keypress responses. Entrainment to the beat was apparent: First-response latency clustered around the standard interval and was positively correlated with the produced interval. However, responses occurring on or near the beat showed no better temporal fidelity than off-beat responses. One plausible interpretation of these findings is that the brain always times brief intervals with an interval timer; however, this timer can be used in a cyclic fashion to trigger rhythmic responses.     

Equality, Justice, and Paternalism: Recentreing Debate about Physician-Assisted Suicide

abstract   Debate about physician-assisted suicide has typically focused on the values of autonomy and patient wellbeing. This is understandable, even reasonable, given the import-ance of these values in bioethics. However, these are not the only moral values there are. The purpose of this paper is to examine physician-assisted suicide on the basis of the values of equality and justice. In particular, I will evaluate two arguments that invoke equality, one in favour of physician-assisted suicide, one against it, and I will eventually argue that a convincing equality-based argument in support of physician-assisted suicide is available. I will conclude by showing how an equality-based perspective transforms some secondary features of debate about this issue.     

Importance and Explanatory Relevance: The Case of Mathematical Explanations

A way to argue that something (e.g. mathematics, idealizations, moral properties, etc.) plays an explanatory role in science is by linking explanatory relevance with importance in the context of an explanation. The idea is deceptively simple: a part of an explanation is an explanatorily relevant part of that explanation if removing it affects the explanation either by destroying it or by diminishing its explanatory power, i.e. an important part (one that if removed affects the explanation) is an explanatorily relevant part. This can be very useful in many ontological debates. My aim in this paper is twofold. First of all, I will try to assess how this view on explanatory relevance can affect the recent ontological debate in the philosophy of mathematics—as I will argue, contrary to how it may appear at first glance, it does not help very much the mathematical realists. Second of all, I will show that there are big problems with it.
