The indeterminacy failures of moral cosmopolitanism and liberal nationalism

Much of the discussion on cosmopolitanism and nationalism has focused on their different normative views. The purpose of this article is to shift the attention away from the normative debate to the metatheoretical argument about how we determine moral and political principles independently of each other. I argue that the discussion among proponents of cosmopolitanism and contextualist models boils down to latent methodological and metatheoretical assumptions about what selection of facts are considered politically relevant. In the article, I explore what I call ‘the indeterminacy failure’ of moral cosmopolitanism, that is, the view according to which moral principles fail to determine what political-institutional level might be preferable; and the ‘indeterminacy failure’ of liberal nationalism, that is, the view according to which national identity fails to determine moral principles. In opposition to dichotomist cosmopolitan models (including various nonideal types of moral cosmopolitanism) and alternative contextualist approaches (including the practice-dependence thesis and liberal nationalism), I promote a ‘split-level’ model that is set to avoid the difficulties in the other approaches. The split-level corrects the indeterminacy failures of cosmopolitanism and contextualism by distinguishing clearly between the level of moral theorising and the level of political theorising.     

Age differences in what is viewed and remembered in complex conjunction search

Older and younger adults searched arrays of 12 unique real-world photographs for a specified object (e.g., a yellow drill) among distractors (e.g., yellow telephone, red drill, and green door). Eye-tracking data from 24 of 48 participants in each age group showed generally similar search patterns for the younger and older adults but there were some interesting differences. Older adults processed all the items in the arrays more slowly than the younger adults (e.g., they had longer fixation durations, gaze durations, and total times), but this difference was exaggerated for target items. We also found that older and younger adults differed in the sequence in which objects were searched, with younger adults fixating the target objects earlier in the trial than older adults. Despite the relatively longer fixation times on the targets (in comparison to the distractors) for older adults, a surprise visual recognition test revealed a sizeable age deficit for target memory but, importantly, no age differences for distractor memory.     

Growth and pruning of mushroom body Kenyon cell dendrites during worker behavioral development in the paper wasp, Polybia aequatorialis (Hymenoptera: Vespidae)

Adult workers of some social insect species show dramatic behavioral changes as they pass through a sequence of task specializations. In the paper wasp, Polybia aequatorialis, female workers begin adult life within the nest tending brood, progress to maintaining and defending the nest exterior, and ultimately leave the nest to forage. The mushroom body (MB) calyx neuropil increases in volume as workers progress from in-nest to foraging tasks. In other social Hymenoptera (bees and ants), MB Kenyon cell dendrites, axons and synapses change with the transition to foraging, but these neuronal effects had not been studied in wasps. Furthermore, the on-nest worker of Polybia wasps, an intermediate task specialization not identified in bees or ants, provides the opportunity to study pre-foraging worker class transitions. We asked whether Kenyon cell dendritic arborization varies with the task specialization of Polybia workers observed in the field near Monteverde, Costa Rica. Golgi-impregnated arbors in the lip and collar calyces, which receive a predominance of olfactory and visual input, respectively, were quantified using Sholl’s concentric circles and a novel application of virtual spherical probes. Arbors of the lip varied in a manner reminiscent of honeybees, with foragers having the largest and in-nest workers having the smallest arbors. In contrast, arbors of the collar were largest in foragers but smallest in on-nest workers. Thus, progression through task specializations in P. aequatorialis involves subregion specific dendritic growth and regression in the MB neuropil. These results may reflect the sensitivity of Kenyon cell dendritic structure to specialization dependent social and sensory experience.     

Emotional labour demands,wages and gender: A within‐person,between‐jobs study

Although research suggests the important role of gender in emotional labour, its effect on the relationship between emotional labour demands and wages has not been examined explicitly. The current study investigates this relationship by testing hypotheses derived from theories of vocational choice and labour market supply and demand. Hypotheses are tested using a unique within‐person, between‐jobs longitudinal dataset with information on two jobs for each worker in a national sample of U.S. workers (N=5,488). After controlling for relevant variables related to wages, results suggest men incur wage penalties of approximately 6% when moving to occupations with higher emotional labour demands. Women do not experience statistically significant wage effects from moving to an occupation with higher emotional labour demands. These findings are discussed and interpreted based on the theoretical frameworks.     

Who gets a mentor? A longitudinal assessment of the rising star hypothesis

This study assessed the rising star hypothesis, which proposes that individuals who are on the fast track to career success are more likely to gain mentors than others. The study used a sample of employees who had never been mentored and examined the relationship between rising star attributes measured at Time 1 and the attainment of a mentor a year later. In support of the hypothesis, individuals who were on the fast-track for promotion, had higher advancement expectations, and engaged in more proactive career behaviors were more likely to gain a mentor than individuals lacking these attributes. Implications of these results for the theory, research and practice of mentoring are discussed.

The Consequences of Terrorism: Disentangling the Effects of Personal and National Threat

The events of 11 September 2001 have led to a higher perceived risk of terrorism in the United States. A better understanding of the political consequences of 9/11 requires a more complete accounting of the nature and consequences of perceived threat. Here, the distinction between perceived personal and national risks is examined in terms of two competing hypotheses: (1) The personal threat of terrorism has a pervasive influence even on national decisions and perceptions, in line with its highly arousing nature. (2) The effects of personal threat are highly circumscribed and overshadowed by the impact of perceived national threat, consistent with findings on the meager impact of self–interest and other personal concerns on public opinion. A survey of 1,221 residents of Long Island and Queens, New York, explored the degree to which personal and national threat affect perceptions of the consequences of, and possible solutions to, terrorism. As expected, there was a clear distinction between perceived personal and national threat, although the two are related. Perceived personal threat did not influence the perceived economic consequences of terrorism, although it had a narrow effect on personal behaviors designed to minimize risk. Overall, the findings imply that the effects of personal threat are circumscribed, consistent with past research on the limited personal basis of political judgments. However, the tests of these hypotheses were constrained by a limited set of dependent variables that included national consequences but not policy solutions designed to limit terrorism.     

Midlife Educational,Career, and Family Outcomes of Women Educated at Two Single-Sex Colleges

We examined midlife educational, career, and family outcomes of women who attended prestigious women's colleges in the 1960s. One college had a coeducational learning environment (CLE), the other was a single-sex environment (SLE). We hypothesized that in CLEs, exposure to men's standards of achievement might have resulted in greater educational and career status outcomes but more discrimination; in SLEs, there might have been fewer opportunities to engage with men intellectually, which could lead to lesser educational and career status outcomes, but the environment might have felt more supportive. Graduates of both colleges were very accomplished 30 years after graduation; however, those who had experienced a CLE reported more sexism and more active involvement in the women's movement than SLE graduates.     

The Relationship of Pregnancy Status to Job Satisfaction: An Exploratory Analysis

Forty-three women who had worked outside of the home prior to becoming pregnant and had returned to the same place of employment after the birth of their children participated in the study. To do so, they responded to a two-part questionnaire asking about their work lives (e.g., level of job satisfaction before, during, and after their pregnancies) and demographic characteristics (e.g., occupation). The results indicated that their job satisfaction was significantly greater before their pregnancies than either during or after their pregnancies. Job satisfaction during pregnancy had a significant, positive correlation with satisfaction with organizational maternity leave policies. Perceived reactions from women's coworkers and supervisors were also examined. Implications for these findings for organizations are discussed. Limitations of the study, and how they might be rectified in future research, are also addressed.     

Motor learning-dependent synaptogenesis is localized to functionally reorganized motor cortex.

The regional specificity and functional significance of learning-dependent synaptogenesis within physiologically defined regions of the adult motor cortex are described. In comparison to rats in a motor activity control group, rats trained on a skilled reaching task exhibited an areal expansion of wrist and digit movement representations within the motor cortex. No expansion of hindlimb representations was seen. This functional reorganization was restricted to the caudal forelimb area, as no differences in the topography of movement representations were observed within the rostral forelimb area. Paralleling the physiological changes, trained animals also had significantly more synapses per neuron than controls within layer V of the caudal forelimb area. No differences in the number of synapses per neuron were found in either the rostral forelimb or hindlimb areas. This is the first demonstration of the co-occurrence of functional and structural plasticity within the same cortical regions and provides strong evidence that synapse formation may play a role in supporting learning-dependent changes in cortical function.
