Research assistantships have long been viewed as an extension of the formal education process, a form of apprenticeship, and a pathway into the professional practice of research in institutional settings. However, there are other contexts in which researchers practice research. Our self-reflective analysis identified that RAship experiences during the masters and the PhD may serve developmentally foundational roles in the advancement of an RA’s knowledge, skills, and passion for research. Further, analysis of participants’ experiences revealed that RA supervisors play critical (...) roles in the development of RAs as researchers. We conclude with the understanding that RAships may be formative in contributing to the development of individuals who go on to specialise as professional research consultants as research consulting is a natural extension of the RA role. Students entering into RAships, current RAs, new faculty members, current RA supervisors, faculty members looking to improve their research productivity, and Chairs of departments will all benefit from reading this paper and its contribution to the current understanding of how RAships impact the development of researchers, and specifically how RAships contribute to the development of research consultants.

Is the United States "the land of equal opportunity" or is the playing field tilted in favor of those whose parents are wealthy, well educated, and white? If family background is important in getting ahead, why? And if the processes that transmit economic status from parent to child are unfair, could public policy address the problem? Unequal Chances provides new answers to these questions by leading economists, sociologists, biologists, behavioral geneticists, and philosophers.New estimates show that intergenerational inequality in the United (...) States is far greater than was previously thought. Moreover, while the inheritance of wealth and the better schooling typically enjoyed by the children of the well-to-do contribute to this process, these two standard explanations fail to explain the extent of intergenerational status transmission. The genetic inheritance of IQ is even less important. Instead, parent-offspring similarities in personality and behavior may play an important role. Race contributes to the process, and the intergenerational mobility patterns of African Americans and European Americans differ substantially.Following the editors' introduction are chapters by Greg Duncan, Ariel Kalil, Susan E.

ObjectivePhysical isolation measures, known as lockdown or shelter-in-place, experienced during coronavirus disease 2019 have the potential to cause psychological distress. This study was conducted to examine parents’ perceived stress and whether reports of rewards and challenges during lockdown impact stress.MethodsData were collected using a cross-sectional online survey in New South Wales, Australia, across the 4-week lockdown. The survey was completed by 158 parents of children aged under 6 years. Stress was measured using the short form of the Perceived Stress Scale. (...) Rewards and challenges were reported in response to two open-ended questions.ResultsThere was a weak negative correlation between PSS-4 scores and days in isolation, with parents who had spent longer in isolation reporting fewer stress symptoms. The relationship between time in isolation and stress was moderated by the degree to which parents described more rewards than challenges: parents who perceived high rewards and low challenges reported lower PSS-4 scores with more days in lockdown, whereas parents who perceived low rewards and high challenges reported higher PSS-4 scores with more days in lockdown. The moderation model examining associations between time in isolation and rewards ratio explained 13% of the variance in PSS-4 scores.ConclusionLockdowns are not uniformly or consistently negative experiences for parents. Identifying positive aspects of the experience may serve to buffer negative mental health risks across time. Understanding resilience strategies is critical for supporting current psychological wellbeing and to adequately prepare for future pandemic experiences. (shrink)

Derogatory terms can be powerful mechanisms of subordination, while re-appropriating these terms can be a strategy to fight back against social injustice. I argue that projects seeking to reclaim slurs have a performative structure that raises particular hazards. Whereas more familiar forms of protest may fail to bring about their intended result, attempts to re-appropriate slurs can fail to be understood as transgressive acts at all. When attempts at reclamation fail, their force is distorted; context and convention lead the hearer (...) to give uptake to the speech act as a traditional deployment of the slur. The force of this traditional use is to validate and re-entrench the very norms the act was intended to subvert. This is the precarious structure of reclamation projects: when successful, reclamation is the subversion of powerful mechanisms of oppression, but when unsuccessful, the act has the ironic force of constituting mechanisms of oppression.

Étude historique et critique des principaux courants qui témoignent de la réflexion morale en Grande-Bretagne : l'intuitionnisme, l'utilitarisme et l'idéalisme au 19e siècle; les conceptions métaéthiques, le réalisme moral et les théories de la vertu au 20e siècle. [SDM].

A convenient and practical method is presented for the generation of unbiased random sequences. The method is based on combining discrete outputs and does not require either precisely specified and unbiased input or complex procedures and equipment.

Motivated by results on interactive proof systems we investigate an ∃-∀hierarchy over P using word quantifiers as well as two types of set quantifiers. This hierarchy, which extends the polynomial-time hierarchy, is called the analytic polynomial-time hierarchy. It is shown that every class of this hierarchy coincides with one of the following Classes: ∑math image, Πmath image , PSPACE, ∑math image or Πmath image . This improves previous results by Orponen [6] and allows interesting comparisons with the above mentioned results (...) on inter-active proof systems. (shrink)

The Kolmogorov complexity of a finite binary string is the length of the shortest description of the string. This gives rise to some ‘standard’ lowness notions for reals: A isK-trivial if its initial segments have the lowest possible complexity and A is low forKif using A as an oracle does not decrease the complexity of strings by more than a constant factor. We weaken these notions by requiring the defining inequalities to hold only up to all${\rm{\Delta }}_2^0$orders, and call the (...) new notions${\rm{\Delta }}_2^0$-bounded K-trivialand${\rm{\Delta }}_2^0$-bounded low for K. Several of the ‘nice’ properties ofK-triviality are lost with this weakening. For instance, the new weaker definitions both give uncountable set of reals. In this paper we show that the weaker definitions are no longer equivalent, and that the${\rm{\Delta }}_2^0$-boundedK-trivials are cofinal in the Turing degrees. We then compare them to other previously studied weakenings, namelyinfinitely-often K-trivialityandweak lowness for K. We show that${\rm{\Delta }}_2^0$-boundedK-trivial implies infinitely-oftenK-trivial, but no implication holds between${\rm{\Delta }}_2^0$-bounded low forKand weakly low forK. (shrink)

I was led to philosophy by politics. There can be no foundation for political action except in ethics; and there can be no foundation for ethics except in some form of metaphysics, whether religious or other. And one cannot travel very far along the philosophic road— particularly if one has in mind the need of arriving at some definite destination—without finding as an obstacle the perennial problem of Free Will. It is an obstacle which has somehow to be crossed. It (...) cannot be evaded or ignored. The man who is dealing with public affairs—with the principles of Criminal Law, for example, or with the factors that make for peace or war, and indeed with any of the major questions that confront our society—if he tries to think things out, is faced constantly by the problem of individual human responsibility; just as the man of religion is faced by it constantly.
