Is Global Poverty a Philosophical Problem?

Peter Singer’s groundbreaking call to action in 1972, “Famine, Affluence, and Morality,” drew philosophical attention to the topic of famine and the associated suffering or preventable death of many throughout the world. Yet despite the volume of philosophical work Singer’s paper inspired, it would still be easy to suppose that global poverty is not a problem for philosophers to take seriously in itself but is rather a particularly stark illustration or instance of a more general problem, whether in ethics or in political philosophy. The aim of this paper is to argue that the philosophical landscape of global poverty is both sui generis and sufficiently complex that the topic should be considered not as an instance of a more general philosophical problem but as a distinct area of normative inquiry.     

The Snow White problem

Synthese - The Snow White problem is introduced to demonstrate how learning something of which one could not have learnt the opposite (due to observer selection bias) can change an agent’s...     

Cue usage in memory for location when orientation is fixed

In previous research, it was demonstrated that including one or three cues surrounding a circular field had no effect on spatial memory for dot locations when the field's orientation was fixed, but that there were very large effects when orientation varied across trials (Fitting, Wedell, & Allen, 2007). In four new experiments, we explored the use of external cues in the fixed orientation environment, using 0, 4, 8, or 24 cues and manipulating task difficulty. In Experiments 1-3, the angular bias data supported the use of four quadrant-based prototypes regardless of cue condition, but there were clear cue effects on radial prototype locations. Increasing the number of cues enhanced accuracy of spatial memory for targets closer to cues. In Experiment 4, we severely challenged memory by using multiple targets and a filled delay before estimation. Doing so demonstrated an effect of cues on the categorical structuring of memory. Collectively, findings indicate that when orientation is fixed, cues bolster fine-grain memory, but that they only alter the default categorical scheme when memory demands are high.     

Toddlers' use of cues in a search task

Search for a ball that has undergone hidden motion rapidly improves during the second year of life (Dev. Psychol., 2000; 36 :394–401). In three experiments we investigated whether the poor performance of younger toddlers was due to attentional failure by highlighting the major cue for the hidden object. We observed only slight improvement in search behaviour. We performed two other experiments that tested the depth of understanding of 3‐year‐olds in this task and found that their performance was robust to changes in the apparatus and experimental procedures. Overall, the results point to a rapidly developing ability in the second year of life to either reason about space or select the correct motor response in search tasks.

The Relationship Between Volunteers' Work Behaviors and Background and Preparation Variables

Increasingly, a large number of individuals provide volunteer services. Demographic information known about these individuals is also increasing. Although recent efforts have attempted to examine more closely the relationships between demographic and background variables and subsequent volunteer motivation and retention, few have studied how these variables impact actual work performed by volunteers. This study provides a model for how volunteers' demographic and background variables may be related to volunteers' perceptions of the frequency and importance of their work behaviors. Although it is possible that motivation also may be related to work behaviors, this study provides information ultimately leading to a more complete picture of the potential impact of demographic and background variables on work behaviors.     

Association of Behavioral Self-Regulation with Concurrent Functional Capacity Among Stroke Rehabilitation Patients

The purpose of this study was to test the hypothesis that the Behavioral Dyscontrol Scale (BDS), a measure of the executive cognitive capacity to use an intention to guide purposeful, goal-directed activity would be strongly associated with concurrent functional status after controlling for age, sex, education, severity of pain, medical comorbidity, depression, and general mental status, in a sample of 246 elderly inpatients receiving rehabilitation services following hospitalization for stroke. Functional status was assessed by rehabilitation nurses' ratings of patients on 11 ADL items and on the Barthel Index. The BDS was the strongest predictor for 11 of the 12 dependent variables. Although it correlated significantly with all outcomes, the MMSE entered only one of the regression models. Of the other covariates, only age and severity of pain made an additional contribution to the prediction of functional ability for more than 1 dependent variable. Consistent with prior results in several other samples, the ability to use intentions to guide purposeful behavior appears to be an important contributor to everyday functioning among older adults.     

The Effects of Gender,Dysphoria, and Performance Feedback on the Accuracy of Self-Evaluations

Two experiments tested hypotheses derived from previous research by Beyer (1990, 1998, 1999a; Beyer & Bowden, 1997) and research on depressive realism. It was predicted that gender differences in the accuracy of self-evaluations of performance will be found on a mathematics test (masculine task), but not on an English test (feminine task) or on history and geography tests (neutral tasks). Furthermore, it was hypothesized that dysphorics are not more accurate self-evaluators than are nondysphorics and that the effect of gender on the accuracy of self-evaluations is moderated by dysphoria. Finally, it was predicted that the provision of performance feedback does not moderate the effect of gender on the accuracy of self-evaluations. These hypotheses were supported. The implications of these findings are discussed.     

"Really? She Blicked the Baby?": Two-Year-Olds Learn Combinatorial Facts About Verbs by Listening

ABSTRACT— Children use syntax to guide verb learning. We asked whether the syntactic structure in which a novel verb occurs is meaningful to children even without a concurrent scene from which to infer the verb's semantic content. In two experiments, 2-year-olds observed dialogues in which interlocutors used a new verb in transitive ("Jane blicked the baby!") or intransitive ("Jane blicked!") sentences. The children later heard the verb in isolation ("Find blicking!") while watching a one-participant event and a two-participant event presented side by side. Children who had heard transitive dialogues looked reliably longer at the two-participant event than did those who had heard intransitive dialogues. This effect persisted even when children were tested on a different day, but disappeared when no novel verb accompanied the test events ( Experiment 2 ). Thus, 2-year-olds gather useful combinatorial information about a novel verb simply from hearing it in sentences, and later retrieve that information to guide interpretation of the verb.     

“Disease-Breeders” Among Us: Deconstructing Race and Ethnicity as Risk Factors of Immigrant Ill Health

Race and ethnicity are well-established epidemiological categories that relate to the patients’ risk of exposure and their susceptibility/resistance to disease. However, this association creates the notion that factors other than a personal identity need not be held responsible for patients’ health problems. This work deconstructs the notion of race and ethnicity as risk factors for immigrant ill health, which is prevalent in current medical research and practice, by tracing its roots in Canadian history. The understanding that medical knowledge is subject to diverse historical, social, cultural and political influences can change the way health professionals perceive their patients as a health threat.     

Linking family dysfunction to suicidal ideation: Mediating roles of self-views and world-views

Research on suicide has documented various factors predicting suicidal ideation. The present study focused on the pathways emanating from one of the external, environmental forces (i.e. family dysfunction) through internal responses (beliefs about oneself and about the world), to suicidal ideation among Hong Kong Chinese. Using structural equation modelling, we tested the mediating roles of depressive self-views (including stress perception, depressive cognition and negative self-esteem) as well as two dimensions of social axioms (social cynicism and negative reward for application). Multi-group analysis showed that the mediation model was invariant across both males and females. Being socialized into a problematic family of origin affected multiple aspects of one's assessments of both oneself and one's world which, in turn, lead to greater suicidal ideation. Our findings provide important implications for assessing suicidal risk and guiding interventions in clinical treatment.
