Life events and personality predicting loneliness among centenarians: findings from the Georgia Centenarian Study

Regarding the purpose of this study, the researchers analyzed the roles that both life events (life-time positive events and life-time negative events) and personality (Neuroticism, Extraversion, Trust, Competence, and Ideas) played in participants of the Georgia Centenarian Study. The researchers analyzed these variables to determine whether they predicted loneliness. Analyses indicated that life-time negative events significantly predicted loneliness. In essence, the higher was the number of life-time negative life events, the higher was the loneliness score. Moreover, Neuroticism, Competence, and Ideas were all significant predictors of loneliness. The higher was the level of Neuroticism and intellectual curiosity, the higher was the level of loneliness, whereas the lower was the level of Competence, the higher was the level of loneliness. In addition, both life-time positive and life-time negative life events were significant predictors of Neuroticism. The higher was the number of life-time positive events, the lower was the level of Neuroticism, and the higher was the number of life-time negative events, the greater was the level of Neuroticism. These results indicated that life-time negative events indirectly affect loneliness via Neuroticism. Last, our results indicated that the Competence facet mediated the relationship between lifetime negative life events and loneliness. Life-time negative life events significantly affected centenarians' perceived competence, and Competence in turn significantly affected the centenarians' loneliness. These results as a whole not only add to our understanding of the link between personality and loneliness, but also provide new insight into how life events predict loneliness.     

The Political Justification of Migrant Workers in Alberta,Canada

Considering a series of oil-driven economic booms, the use of inter-provincial and international migrant labour has become an important part of labour market policy in the Canadian province of Alberta. The increased use of temporary foreign workers is controversial. Narrative analysis of legislators’ statements in the legislature and the press between 2000 and 2011 reveals the government using three narratives to justify policies encouraging greater use of foreign migrant workers: (1) labour shortages require migrant workers, (2) migrants do not threaten Canadian jobs and (3) migrants are not being exploited. Close scrutiny of each narrative demonstrates them to be largely invalid. This suggests a significant disconnect between the real and espoused reasons for the significant changes to labour market policy, changes that advantage employers and disadvantage both Canadian and foreign workers. The findings are relevant to understand the political dynamics of economically related migration.     

Seeing is a verb

This commentary on ‘The interaction of attention and action: From seeing action to acting on perception’ by Humphreys et al. (2010) considers selection‐for‐action in relation to the role of parietal cortex corollary discharge in the ‘mastery of sensori‐motor contingencies’ that O'Regan and Noe (2001) suggest gives rise to visual awareness.     

当代“马克思研究”：国家理论的新进展（续）——各种探讨、争论点和议程

近年来,虽然人们对于那些从理论上说明国家的、具有更多的神秘色彩和抽象色彩的方式兴趣越来越小,但是,对于各种国家和国家权力的实质性研究却呈现出突破性的发展。即使对因此而出现的献的一小部分进行回顾也是不可能的,但是,我们仍然有必要提到其中的五个论题——这五个论题促进了我们上面讨论的这些探讨的对立。     

The temporal organization of functional brain connectivity is abnormal in schizophrenia but does not correlate with symptomatology

Previous work employing graph theory and nonlinear analysis has found increased spatial and temporal disorder, respectively, of functional brain connectivity in schizophrenia. We present a new method combining graph theory and nonlinear techniques that measures the temporal disorder of functional brain connections. Multichannel electroencephalographic data were windowed and functional networks were reconstructed using the minimum spanning trees of correlation matrices. Using a method based on Shannon entropy, we found elevated connection entropy in gamma activity of patients with schizophrenia; however, gamma connection entropy remained elevated in patients with schizophrenia even after a reduction in symptoms due to treatment with antipsychotics. Our results are consistent with several possibilities: (1) aberrant functional connectivity is epiphenomenal to schizophrenia, (2) aberrant functional connectivity is a central feature but antipsychotics reduce symptoms by an independent mechanism, or (3) connection entropy is not an appropriately sensitive measure of brain abnormalities in schizophrenia.     

BECOMING BELIEVERS: STUDYING THE CONVERSION PROCESS FROM WITHIN

Abstract Employing an extended case method ethnography ( Burawoy 1998 ), the researcher joined five new members forming a spiritualist's group under the leadership of an experienced advocate. Over a period of eighteen months, the researcher attended all the group's activities and events. Data were collected to reflexively interrogate the process theory of conversion proposed by Lewis Rambo (1993) . The data revealed conversion to be a multifaceted and dynamic process of cognitive change, mediated by structural, and contextual forces. The results provide a reconceptualization of Rambo's theory, presenting a theoretical expansion of the model emphasizing its mechanisms of action. The paper details the composition of the “Interaction‐Commitment” mechanism, operationalized within four submechanisms emanating from Rambo's roles, rituals, rhetoric, and relationships. This longitudinal study shows that most of the hard work toward conversion occurs before any formal interaction with a conversion advocate. Conversion operates most effectively under conditions of cognitive economy wherein the belief path follows a path of least cognitive expenditure.
