Neuropsychology and cognitive health in healthy older adults: a brief overview for psychiatric nurses

This article contains a brief synopsis on nonpathological aspects of the neuropsychology of aging and cognitive health. In nonpathological aging, normal subtle decline occurs in a number of cognitive domains such as executive functioning, speed of processing, memory, language, and psychomotor ability; however, some domains of cognitive functioning appear to increase with age, such as vocabulary and crystallized intelligence. In the neuropsychology and the cognitive aging literatures, several hypotheses for such age-related declines are proposed, including the diminished speed-of-processing hypothesis, the common cause hypothesis, and the frontal aging hypothesis. As these age-related changes diminish cognitive reserve, the decline in the related cognitive domains emerges. Ways to protect and improve cognitive health are suggested to encourage positive neuroplasticity and discourage negative neuroplasticity. Implications for nursing practice are provided.     

Examining the role of racism in the risky alcohol use behaviors of black female college students

Objective: This study explores the impact racism has on the drinking behaviors of Black college women. Little is known about Black college women's experience of racism and the impact racism has on their psychological wellbeing and drinking behaviors. The current study fills a gap in our understanding of the role racism plays in the risky drinking behavior of Black college women. Participants: 469 Black college women ages 18–29 were sampled from 8 colleges and universities across the US, in 3 waves from December 2014-August 2017. Results: Findings suggest that general life stress and perceived racism are significantly associated with alcohol use among Black college women. However, only increased experiences of racism increase Black college women's engagement in risky drinking. Conclusions: The findings of this study serve as an entry point for a more nuanced assessment of stressors among Black college women that may inform drinking behaviors in this population.     

Collective intelligence: Scale development and validation

In today’s growing competition, organizations face shrinking innovation cycles, swelling customer expectations, and distributed talent which impels organizations to apply knowledge, skills, and experience of employees most effectively. Applying collective intelligence, i.e., the combined knowledge and expertise of a diverse group, has become the order of the day. Therefore, collective intelligence level of an individual is of immense importance for high performance and achievement of the goals. In the present research, an attempt is made to operationalize the components of organizational collective intelligence from working professionals. Specifically, an attempt is made to develop a scale to measure collective intelligence among 600 working professionals. The results were subjected to the robust measurement tools such as Exploratory Factor Analysis and Structures Equation Modeling to confirm the factor structure. The instrument resulted in four factors and a 17-item scale. The instrument can be used by the policymakers and human resource managers for selecting, harnessing, and retaining appropriate talent in the organization.     

The views and attitudes of health professionals providing antenatal care to women with a high BMI: A qualitative research study

BackgroundThe prevalence of overweight and obesity is increasing amongst women of child bearing age. The objective of this study was to investigate the views and attitudes of providers of antenatal care for women who have a body mass index (BMI) of 30 kg/m² and over.MethodsA qualitative study using focus groups was undertaken within the department of obstetrics and gynaecology at a large teaching hospital in south-eastern Australia. Three focus group discussions were held. One with hospital midwives (n = 10), one with continuity of care midwives (n = 18) and one with obstetricians (n = 5). Data were analysed using Interpretative Phenomenological Analysis (IPA).FindingsSix dominant themes emerged: (1) obesity puts the health of mothers, babies and health professionals at risk; (2) overweight and obesity has become the norm; (3) weighing women and advising about weight gain is out of fashion; (4) weight is a sensitive topic to discuss; (5) there are significant barriers to weight control in pregnancy; and (6) health professionals and women need to deal with maternal obesity. These themes are drawn together to form a model representing current health care issues for these women.ConclusionHealth professionals, who have a high BMI, can find it difficult to discuss obesity during antenatal visits with obese women. Specialist dietary interventions and evidence based guidelines for working with child-bearing women is seen as a public health priority by health care professionals.     

Ridge Regression for Estimation of Transition Probabilities from Aggregate Data

When data from several independent Markov chains are aggregated over each time point, least square estimation of transition probabilities faces the problem of multi-collinearity. We propose here an estimation procedure which involves use of ridge regression for the ordinary least square estimators. Performance of this estimator is then compared with that of the ordinary least squares.     

Testing goodness of fit in terms of the mean residhal life function

A test based on empirical distribution function had been proposed for testing the goodness of fit of an assigned mean residual life function against a one sided alternative. The test statistic has been shown to be consistent and has an asymptotic normal distribution. The test performance is good in the asymptotic relative efficiency sense.     

Environmental sampling with a concomitant variable: A comparison between ranked set sampling and stratified simple random sampling

In many environmental sampling situations, the variable of interest is either not easily observable or is too expensive to observe. Under such circumstances, the need arises to observe another variable, related to the variable of interest, so as to estimate the population parameters of interest. We study the performance of two different sampling procedures, i.e. ranked set sampling and stratified simple random sampling, when both stratification and ranking are accomplished on the basis of such a concomitant variable. The relative precision of the two methods is obtained and expressed as a function of population variance, between-stratum and between-rank variation, and the correlation coefficient between the variable of interest and the concomitant variable. The relative precision is computed for several important families of distributions that occur frequently in environmental and ecological work. Under equal allocation of sampling units, stratified simple random sampling is found to perform better than ranked set sampling, when the costs incurred to obtain sample measurements are ignored. When optimum allocation is considered for both methods, ranked set sampling performs better than stratified simple random sampling, when the concomitant variable is not highly correlated with the variable of interest. Furthermore, when the costs of sampling and the costs of measurement are incorporated into the assessment of the relative precision, the ranked set sampling is seen to be more efficient than stratified simple random sampling, particularly when the cost of stratification is high compared with that of ranking. This is generally the case in practice.     

The limits of imperial incorporation: Alternative sociological frameworks to study Asian American subjects

This paper argues existing scholarship on Asian American communities is limited by an assumption that incorporation into the US can productively address racial and economic precarity. As an alternative, we offer “Extinguishing Asian (American) Insurgency”, a theoretical framework that incorporates histories of colonialism, imperialism, and postcolonial politics of incorporation into contemporary sociological analyses of Asian subject formation. Applying Du Boisian sociology alongside Frantz Fanon and Joy James, the framework adopts a global, relational analysis of Asian Americans and the US state. We demonstrate the framework's utility through two case studies: anti-colonial Sikh diasporic politics through the Gadar Party and US state efforts to tie diasporic South Vietnamese identity to an anti-communist politic. As such, we encourage the study of alternative possibilities of Asian subject formation that are extinguished by state incorporation, particularly through imperialism and military serivce. Specifically, we address sociologists who extinguish the insurgent Asian American subject in their scholarship by assuming incorporation and pro-state politics as a natural end goal of migration, or those who simply do not name the US as the institutional force extinguishing possibilities of Asian Americans' insurgency.     

Aesthetics of arrival: spectacle,capital, novelty in post-reform India

India’s celebrated ‘arrival on the global stage’ as a desirable ‘emerging market’ for global investors signals the spectacular moment that is said to have ruptured the barriers between the first and third worlds. If the notion of arrival anticipates the long-awaited acceleration in the pace of history, it also harnesses a euphoric India to the limitless future promised by the new. In this special issue, we set our focus on the aesthetics of arrival that signal novelty, visibility and celebration of post-reform India within and outside the nation. We ask how novelty is manufactured and experienced when the majority of the population remains excluded from new India. The answer probably lies in the way in which this other India is signified as the past, as ‘old India’ that holds back the nation. The novelty, we propose, is not only experienced in the promise of the future, but also in the aesthetic force of the promise to overcome a humiliating past, tainted by colonialism, in order to realise a truer and more timeless ‘new’ India
