Is the independence of golf scores for professional golfers a statistical artifact?

This study investigated whether the lack of day-to-day consistency in performance for professional golfers would occur if round ranks were employed instead of round scores. When players' round scores from the 2004 Clark study were converted to round ranks, the results were very similar to those found in that study. It was concluded that the range of abilities for professional golfers is so restricted that the fluctuation in players' scores or rankings will show little consistency from day to day.     

Should We All be Scientists? Re-thinking Laboratory Research as a Calling

In recent years there have been major shifts in how the role of science—and scientists—are understood. The critical examination of scientific expertise within the field of Science and Technology Studies (STS) are increasingly eroding notions of the “otherness” of scientists. It would seem to suggest that anyone can be a scientist—when provided with the appropriate training and access to data. In contrast, however, ethnographic evidence from the scientific community tells a different story. Scientists are quick to recognize that not everyone can—or should—be a scientist. Appealing to notions such as “good hands” or “gut feelings”, scientists narrate a distinction between good and bad scientists that cannot be reduced to education, access, or opportunity. The key to good science requires scientists to express an intuitive feeling for their discipline, but also that individuals derive considerable personal satisfaction from their work. Discussing this personal joy in—and “fittingness” of—scientific occupations using the fields of STS, ethics and science policy is highly problematic. In this paper we turn to theology discourse to analyze the notion of “callings” as a means of understanding this issue. Callings highlight the identification and examination of individual talents to determine fit occupations for specific persons. Framing science as a calling represents a novel view of research that places the talents and dispositions of individuals and their relationship to the community at the center of flourishing practices.     

A methodological note on nonlinear time series analysis: is the open- and closed-loop model of Collins and De Luca (1993) a statistical artifact?

The authors reexamined, theoretically and empirically, the method proposed by J. J. Collins and C. D. De Luca (1993) for the analysis of center-of-pressure trajectories. The main argument in this article is that Collins and De Luca's approach is not adapted to the analysis of bounded time series and leads to statistical artifacts such as underestimation of the diffusion process for long-term intervals. The open- and closed-loop model developed by Collins and De Luca is a direct consequence of those statistical problems. Applying more classical methods, such as rescaled range analysis or detrended fluctuation analysis, the authors show that center-of-pressure trajectories can be modeled as continuous, antipersistent fractional Brownian motion. More specifically, those trajectories behave like 1/f noise, a ubiquitous feature in adaptive biological systems.     

Should providers of treatment be regarded as a random factor? If it ain't broke, don't "fix" it: a comment on Siemer and Joormann (2003)

In their criticism of B. E. Wampold and R. C. Serlin's analysis of treatment effects in nested designs, M. Siemer and J. Joormann argued that providers of services should be considered a fixed factor because typically providers are neither randomly selected from a population of providers nor randomly assigned to treatments, and statistical power to detect treatment effects is greater in the fixed than in the mixed model. The authors of the present article argue that if providers are considered fixed, conclusions about the treatment must be conditioned on the specific providers in the study, and they show that in this case generalizing beyond these providers incurs inflated Type I error rates.     

Should we be Kantians? A Defence of Empricism (Part Two)

In his book Mind and World (1994), John McDowell defends the Kantian position that the content of experience is conceptual. Without this Kantian assumption, he argues, it would be impossible to understand how experience may rationally constrain thought. But McDowell's Kantianism is either false or empty, and his view of the relation between mind and world cannot be stated without transcending the bounds of sense. McDowell's arguments supporting the Kantian thesis, which are very different from Kant's arguments, essentially involve a fallacy of ambiguity. In order to understand how thought may be rationally constrained by experience we should become empiricists.     

Should DBS for Psychiatric Disorders be Considered a Form of Psychosurgery? Ethical and Legal Considerations

Deep brain stimulation (DBS), a surgical procedure involving the implantation of electrodes in the brain, has rekindled the medical community’s interest in psychosurgery. Whereas many researchers argue DBS is substantially different from psychosurgery, we argue psychiatric DBS—though a much more precise and refined treatment than its predecessors—is nevertheless a form of psychosurgery, which raises both old and new ethical and legal concerns that have not been given proper attention. Learning from the ethical and regulatory failures of older forms of psychosurgery can help shed light on how to address the regulatory gaps that exist currently in DBS research. To show why it is important to address the current regulatory gaps within psychiatric DBS, we draw on the motivations underlying the regulation of earlier forms of psychosurgery in the US. We begin by providing a brief history of psychosurgery and electrical brain stimulation in the US. Against this backdrop, we introduce psychiatric DBS, exploring current research and ongoing clinical trials. We then draw out the ethical and regulatory similarities between earlier forms of psychosurgery and psychiatric DBS. As we will show, the factors that motivated strict regulation of earlier psychosurgical procedures mirror concerns with psychiatric DBS today. We offer three recommendations for psychiatric DBS regulation, which echo earlier motivations for regulating psychosurgery, along with new considerations that reflect the novel technologies used in DBS.     

Why Should I Respect You? A Critique and a Suggestion for the Justification of Mutual Respect in Contractualism

Contractualism is a normative theory which characterizes principles of right in terms of the idea of mutual respect. In this theory, mutual respect is regarded as having deliberative priority over other values. This essay aims to examine how contractualists can provide a satisfactory justification for prioritizing mutual respect. I will argue that the “value of mutual respect argument,” which is a justification commonly adopted by contractualists, is inadequate because an unconditional priority of mutual respect cannot be grounded on the desirability of a relationship of mutual respect. Then, I will suggest that a “consistency argument” can provide a better justification of why the idea of mutual respect should have priority. Mutual respect is of special importance, not because it is highly desirable, but rather because it is required by an a priori guiding principle of consistency. Individuals become inconsistent if they ask others to respect them as reason-assessing individuals, while at the same time refusing to respect others in the same way.     

Can blindness to response-compatible stimuli be observed in the absence of a response?

Blindness to response-compatible stimuli is the finding that targets are identified less accurately when presented during the planning or execution of a congruent response (e.g., right arrow presented during a right keypress) versus an incongruent response (e.g., right arrow presented during a left keypress). Accounts of this effect suggest the planning and execution of a response are critical to its observation. Five experiments investigated whether a blindness effect would be observed in the absence of a planned response. Results suggest that a planned response is not necessary to observe a content-specific blindness effect and that the blindness effect may actually comprise both an action-related component and a symbolic component that is distinct from the action-planning system.     

Can independence be observed in a dependent system? The case of tip-of-the-tongue states.

Caramazza and Miozzo (1997) found that speakers experiencing tip-of-the-tongue states are able to report phonological information independently from syntactic information. They used this finding to reject sequential models of production, in which syntactic units (lemmas) are retrieved before form units (lexemes). To see whether this conclusion is warranted, we performed two simulation experiments based on sequential architectures. Both models we simulated produced statistically uncorrelated syntax and phonology despite sequentially retrieving lemmas and lexemes. Finally, we analyzed a corpus of Spanish errors, finding syntactic constraints on phonological word substitution errors that are not easily explained without sequentiality.     

Should supportive measures and relational variables be considered a part of psychoanalytic technique? Some empirical considerations

This article presents some quantitative findings from a survey of 89 psychoanalysts (all members of the American Psychoanalytic Association or the International Psychoanalytical Association) about their own experiences in analysis. A comprehensive questionnaire was used to collect retrospective data about (1) how participants felt they benefited from their analyses and (2) how they remembered their analysts’ technique, personality, and style of relating. A correlational analysis found that, according to our participants’ ratings, the most beneficial analyses were associated with having a caring and emotionally engaged analyst who possessed positive relational and personality qualities, used supportive techniques in addition to classical techniques, and pursued therapeutic as well as analytic goals. Outcomes rated as successful were also associated with experiencing a good ‘fit’, a good working relationship, and a positive therapeutic alliance. Our results support the call for an expanded view of acceptable analytic technique (e.g. Schacter and Kächele, 2007) .     

Who Should Get a Say? Race,Law Enforcement Guidelines,and Systems of Representation

Most citizens agree that legislators should reflect their constituencies' stances. Yet constituents rarely speak in a single voice. Instead, constituents often vary not only in their policy preferences, but also in the degree to which a given policy impacts their lives. Politicians thus at times pursue targeted representation, offering increased input to especially affected groups. As efforts to address anti-Black police misconduct make clear, such measures can protect vulnerable minority groups—but they may also be perceived to sideline the less-affected majority. We fielded two national survey experiments to investigate how Americans respond when legislators give more attention to some citizens than others. Results suggest that members of targeted groups react more positively on average than nonmembers and that reactions among nonmembers are strongly driven by racial resentment. The impact of racial resentment is largely unaffected by the race and partisanship of the politician proposing the measure, but it is exacerbated in cases of a clear preference conflict between the African American community and the broader constituency.     

Can we be (and stay) friends? Remaining friends after dissolution of a romantic relationship

Although many individuals report being friends with their ex-romantic partners (Wilmot, Carbaugh, & Baxter, 1985), the literature regarding post-romantic friendships is very limited. We investigated whether satisfaction in the dissolved romantic relationship could predict post-romantic friendships and friendship maintenance. We found that the more satisfied individuals were during the dissolved romance, the more likely they were to remain friends and the more likely they were to engage in friendship maintenance behaviors. We also found that friendship maintenance fully mediated the association between past romantic satisfaction and current friendship satisfaction.     

Should subjects be forewarned of the possible psychological consequences of filling out a PTSD questionnaire?

In 1993 Albach investigated the long-term consequences of sexual abuse on psychological health. A group of abused women a a control group of nonabused women were asked to fill in a questionnaire assessing posttraumatic stress disorder (PTSD). For ethical reasons, the abused women were warned that filling in the questionnaire might be emotionally stressful. The control group did not receive this warning. The abused women scored higher on the questionnaire than the nonabused women. The warning they received may have influenced their reports. Our experiment investigated this. 101 psychology students were divided into two groups, one who received a warning and a control group who did not. The hypothesis was that people who had been previously warned would score higher on a PTSD questionaire than people who had not. There were, however, no significant differences in mean PTSD scores and no known initial differences between groups.     

Is There a Role for Publication Consultants and How Should Their Contribution be Recognized?

When a scientific paper, dissertation or thesis is published the author(s) have a duty to report who has contributed to the work. This recognition can take several forms such as authorship, relevant acknowledgments and by citing previous work. There is a growing industry where publication consultants will work with authors, research groups or even institutions to help get their work published, or help submit their dissertation/thesis. This help can range from proof reading, data collection, analysis (including statistics), helping with the literature review and identifying suitable journals/conferences. In this opinion article we question whether these external services are required, given that institutions should provide this support and that experienced researchers should be qualified to carry out these activities. If these services are used, we argue that their use should at least be made transparent either by the consultant being an author on the paper, or by being acknowledged on the paper, dissertation or thesis. We also argue that publication consultants should provide an annual return that details the papers, dissertations and thesis that they have consulted on.     

Should Kohlberg's cognitive developmental approach to morality be replaced with a more pragmatic approach? Comment on Krebs and Denton (2005)

Krebs and Denton (2005) proposed that Kohlberg's cognitive developmental approach to morality be replaced by a pragmatic approach more relevant to everyday social behavior and the cooperative moral orders of society. Although the Krebs and Denton article raises some legitimate questions, their proposal is at best premature and provokes some serious concerns. Their starting point, that Kohlberg's model of morality is inadequate, is an evaluation shared by many neo-Kohlbergians. Before the cognitive developmental approach is replaced, however, important contributions (e.g., Rest's schema interpretation of the stages) toward refining or improving the approach must be adequately considered. Evidence suggests that Krebs and Denton may have underestimated relations between moral judgment stages and social behavior, including sudden behavior in emergency situations.
