Species are Processes: A Solution to the ‘Species Problem’ via an Extension of Ulanowicz’s Ecological Metaphysics

The ??species problem?? in the philosophy of biology concerns the nature of species. Various solutions have been proposed, including arguments that species are sets, classes, natural kinds, individuals, and homeostatic property clusters. These proposals parallel debates in ecology as to the ontology and metaphysics of populations, communities and ecosystems. A new solution??that species are processes??is proposed and defended, based on Robert Ulanowicz??s metaphysics of process ecology. As with ecological systems, species can be understood as emergent, autocatalytic systems with propensities for centripetality and mutuality in the course of dynamically balancing ascendency (order and persistence) and overhead (randomness and change). The species-as-processes perspective accords with the Ulanowicz??s postulates of process ecology and it can be accommodated by existing theories of species??particularly in a reframing of Richard Boyd??s metaphysics such that species are homeostatic process clusters. Rather than contending that process-based metaphysics is the only, best or true account of species, a pluralist-realist approach is advocated based on the pragmatic principles that are reflected in modern view of species and ecology. If species are understood to be comprised of processes and to be emergent processes themselves, there are important implications for the life sciences, including: animal models in medical and environmental studies, conservation biology, extinction, biodiversity, restoration ecology, and evolutionary biology.     

School barricaded captive-taking: A literature review and critique

Although schools are among the safest places for children and youth, they are the occasional site of violent behavior. One form of violence is the barricaded-hostage event. In this article, the authors review the research literature pertaining to these events. Specifically, studies examining the impact on direct and indirect victims, and responders to these events, are presented and critiqued. Recommendations for future research are also made, followed by a summary and conclusions.     

Does Moral Virtue Require Knowledge? A Response to Julia Driver

A long-standing tenet of virtue theory is that moral virtue and knowledge are connected in some important way. Julia Driver attacks the traditional assumption that virtue requires knowledge. I argue that the examples of virtues of ignorance Driver offers are not compelling and that the idea that knowledge is required for virtue has been taken to be foundational for virtue theory for good reason. I propose that we understand modesty as involving three conditions: 1) having genuine accomplishments, 2) being aware of the value of these accomplishments, and 3) having a disposition to refrain from putting forward one’s accomplishments. When we understand modesty this way, we can properly identify genuine cases of modesty and see how modesty requires knowledge. Something similar can be said about other alleged virtues of ignorance. With the proposal in place, we have no serious reason to think that moral virtue requires ignorance. Additionally, we have good reasons for thinking that acting virtuously requires having good intentions and that a necessary condition of having a virtue is having knowledge. Although some might take these results to be trivial or obviously true, I think the Julia Driver’s challenge should not be dismissed out of hand. Even though there are some reasons for thinking that some situations suggest that knowledge and virtue can be separated from one another, close analysis reveals this impression is only surface deep.     

A qualitative investigation into the online counselling relationship: To meet or not to meet,that is the question

Background and aim: Online counselling, as a psychotherapeutic approach, provokes debate amongst practitioners and researchers concerning its efficacy and validity. This reflexive study extends existing research into the nature of the online counselling relationship when it is conducted asynchronously (by email) and explores the possibility this approach may facilitate both online and face‐to‐face therapeutic engagement. Method: Semi‐structured interviews were conducted electronically with ten former email counselling clients of a university counselling service and six counsellors delivering email counselling in other higher education settings, to explore, in depth, their experiences of the online therapeutic relationship and its impact on the counselling process and outcomes. These were analysed using Interpretative Phenomenological Analysis (IPA). Findings: Four areas of focus emerged relating to: (1) the importance of the structure and processes involved; (2) their impact on thinking and feeling; (3) their impact on self and relationships (within and outside counselling), and (4) changes that followed email counselling. Having ‘time to think’ within the asynchronous exchanges, the anonymity and disinhibition afforded by the online medium, the creation of transitional space and the rich use of metaphor, visualisation and imagery all contributed to a sense of empowerment and relational depth for individuals who might have otherwise avoided seeking help. This led to positive change in many cases and for some, facilitated subsequent face‐to‐face counselling. Implications: The findings support the provision of counselling and therapy online and particularly its integration within existing face‐to‐face services.     

Domain-specific perfectionism in intercollegiate athletes: Relationships with perceived competence and perceived importance in sport and school

ObjectivesTo examine the domain-specific nature of perfectionism in sport and school, and to examine potential links between domain-specific perceived competence, perceived importance (task value), and perfectionism in sport and school.Design and MethodA total of 255 male and female varsity student-athletes from a successful intercollegiate sport program completed domain-specific (i.e., sport and school) versions of Hewitt and Flett's (1991) Multidimensional Perfectionism Scale (HF-MPS). Participants also completed an inventory designed to assess perceived competence (PC) in sport versus school and perceived importance (PI) of success in sport versus school.ResultsExploratory factor analyses conducted on perfectionism data indicated that perfectionist orientations were organized around domain-specific as opposed to global perfectionist tendencies. Regression analyses indicated that PC was a significant predictor of domain-specific levels of self-oriented and socially prescribed perfectionism (ps < .05), and PI was a significant predictor of domain-specific levels of self-oriented, socially prescribed, and other-oriented perfectionism (ps < .001). A repeated-measures MANOVA revealed that student-athletes had significantly higher levels of perfectionism in sport than school (ps < .0001) across all three HF-MPS subscales.ConclusionResults reinforce the value of measuring perfectionism as a domain-specific (rather than global) personality disposition, and identify the potential role that perceived competence and perceived importance may play in the development of domain-specific perfectionism.     

Knowledge,beliefs, peer norms,and past behaviors as correlates of risky sexual behaviors among college students

Abstract

HIV/AIDS knowledge, age at onset of sexual activity, perceptions of personal risk and peer norms were explored as correlates for risky sexual behaviors among college students. Ninety-nine male and 185 female college students completed a 66-item questionnaire. A majority reported being sexually active with most in mutually monogamous relationships or not currently in a sexual relationship. Multiple regression correlation analyses showed knowledge about HIV/AIDS to be very high but that this knowledge did not independently relate to the extent of risky behaviors. Perceptions of risk were positively related to number of partners and single-time partners but not condom usage. In contrast to previous studies, perceived peer norms did not independently relate to behaviors. Instead, age at first intercourse was found to have substantial overlap with current perceptions, attitudes, and likelihood for engaging in risky behaviors. The necessity for including previous behaviors in analyses of the impact of attitudes and perceived norms on behavioral intentions is discussed.     

Correlates of satisfaction with body function and body appearance in middle- and older aged adults: The activity counseling trial (ACT)

Abstract

This study examined the dimensional structure and correlates of body satisfaction among middle-aged and older adult men (n = 471) and women (n = 383) who were participants in the Activity Counseling Trial. Correlates were grouped as (1) fitness parameters, (2) demographic characteristics, and (3) components of subjective well-being. Factor analyses demonstrated that body function and body appearance were independent components of satisfaction in this population. Body composition and cardiorespiratory fitness were directly related to satisfaction with body appearance; however, satisfaction with body function was most strongly related in expected directions to measures of subjective well-being. Age was positively related to both measures of body satisfaction, whereas data on race revealed that blacks were more satisfied with their body appearance and function than whites. The observed relationships for body satisfaction suggest that older adults may value body function more than body appearance. Furthermore, the associations of race and age with body satisfaction have important implications for intervention research.     

Incentive Salience and Improved Performance

Using data from 441 call center employees at a large North American financial services firm, we studied how the frequency of thinking about an incentive available for performance led to increased output on an important performance metric. We find that people think more frequently about noncash tangible incentives (merchandise and travel) than cash incentives and that as the frequency of thought increases, performance increases. This leads to a larger performance boost for tangible incentives compared to a cash incentive of equal purchasing power. These results show an additional benefit from the use of tangible incentives and help answer the question regarding the psychological processes which make incentives motivating.     

Developmental Patterns and Use of the Wisconsin Card Sorting Test for Children and Adolescents with Learning Disabilities

This study examined the Wisconsin Card Sorting Test (WCST) by testing 129 children and adolescents with learning disabilities (LD) who were between 7 and 13 years of age. Developmental trends were examined across age groups using scores from the WCST. Several scales yielded developmental patterns, supported by statistically significant main effects for age. Additionally, multiple regression analyses were run examining the relationship of the WCST with other measures. The models yielded were in predicted directions. The results of this study support the clinical utility of the WCST in children and adolescents with LD.
