Differentiating transformational and non-transformational leaders on the basis of neurological imaging

The purpose of this study was to evaluate the viability of using neurological imaging to classify transformational leaders, versus non-transformational leaders, as identified through existing psychometric methods. Specifically, power spectral analysis measures based on electroencephalograms (EEG) were used to develop and validate a discriminant function that can classify individuals according to their transformational leadership behavior. Resting, eyes closed EEG was recorded from 19 scalp locations for 200 civilian and military leaders. We also assessed follower or peer perceptions of transformational leadership through the use of the Multifactor Leadership Questionnaire (MLQ). Our discriminant analysis, which involved a two-step, neural variable reduction and selection process, was 92.5% accurate in its classification of leaders. Patterns in the spectral measures of the brain of leaders, including activity and network dynamic metrics, are discussed as potential correlates of transformational leadership behavior. The current work provides a better understanding of the latent and dynamic neurological mechanisms that may underpin the transformational leadership qualities of individuals.     

An adjusted likelihood ratio test for separability in unbalanced multivariate repeated measures data

We propose an adjusted likelihood ratio test of two-factor separability (Kronecker product structure) for unbalanced multivariate repeated measures data. Here we address the particular case where the within subject correlation is believed to decrease exponentially in both dimensions (e.g., temporal and spatial dimensions). However, the test can be easily generalized to factor specific matrices of any structure. A simulation study is conducted to assess the inference accuracy of the proposed test. Longitudinal medical imaging data concerning schizophrenia and caudate morphology illustrate the methodology.     

The role of mindfulness in romantic relationship satisfaction and responses to relationship stress

Two studies examined the role of mindfulness in romantic relationship satisfaction and in responses to relationship stress. Using a longitudinal design, Study 1 found that higher trait mindfulness predicted higher relationship satisfaction and greater capacities to respond constructively to relationship stress. Study 2 replicated and extended these findings. Mindfulness was again shown to relate to relationship satisfaction; then, using a conflict discussion paradigm, trait mindfulness was found to predict lower emotional stress responses and positive pre- and postconflict change in perception of the relationship. State mindfulness was related to better communication quality during the discussion. Both studies indicated that mindfulness may play an influential role in romantic relationship well-being. Discussion highlights future research directions for this new area of inquiry.     

Burden‐of‐illness vaccine efficacy

In recent years, many vaccines have been developed for the prevention of a variety of diseases. Although the primary objective of vaccination is to prevent disease, vaccination can also reduce the severity of disease in those individuals who develop breakthrough disease. Observations of apparent mitigation of breakthrough disease in vaccine recipients have been reported for a number of vaccine‐preventable diseases such as Herpes Zoster, Influenza, Rotavirus, and Pertussis. The burden‐of‐illness (BOI) score was developed to incorporate the incidence of disease as well as the severity and duration of disease. A severity‐of‐illness score S > 0 is assigned to individuals who develop disease and a score of 0 is assigned to uninfected individuals. In this article, we derive the vaccine efficacy statistic (which is the standard statistic for presenting efficacy outcomes in vaccine clinical trials) based on BOI scores, and we extend the method to adjust for baseline covariates. Also, we illustrate it with data from a clinical trial in which the efficacy of a Herpes Zoster vaccine was evaluated.     

Challenging the inevitability of rural decline: Advancing the policy of place in northern British Columbia

In current policy discourse, rural decline is often described as an inevitable process associated with such broader structural trends as globalization and urbanization. The purpose of this paper is to challenge the supposed inevitability of rural decline in northern British Columbia (BC), Canada. We argue that rural decline in northern BC has been facilitated through an intentional policy program that views hinterland areas as a ‘resource bank’ from which to fund provincial infrastructure and services, without adequate attention to rural reinvestment. We highlight the potential discrepancies of this approach through a comparative study of two development eras in the province. In the first era, we examine the policies and development approach adopted by the W.A.C. Bennett provincial government, which governed from 1952 to 1972. We argue that the Bennett regime confronted the complexity of the post-war era with a comprehensive vision and coordinated policy program for ‘province building’ through intensive investments in industrial expansion and community infrastructure throughout the BC hinterland. By comparison, the post-1980s era in BC has witnessed a continuation of the resource bank approach, minus a concomitant commitment to hinterland investment. Reversing the inevitability of rural decline requires a renovation of the investment orientation witnessed during the Bennett era through an appreciation of the role of place in economic development. Our recommendations for renewed rural development in northern BC are drawn from a synthesis of the Bennett lessons with those emerging within place-based development literature.     

Exploring the Impact of School Discipline on Racial Disproportion in the Juvenile Justice System*

It is widely recognized that African‐American youth are significantly overrepresented in many juvenile justice systems relative to their population percentages. Research has also determined that similar disproportion exists in school discipline and speculated about a “school‐to‐prison pipeline” for minority youth. Objective. This study explores empirically the degree to which disciplinary decisions made in schools can help to explain observed rates of disproportionate minority contact with juvenile courts. Methods. It does so in an assessment of education and justice system data from a sample of counties in Missouri. Results. The findings suggest that racial disproportion in out‐of‐school suspensions, which cannot be explained solely by differences in delinquent behavior, is strongly associated with similar levels of disproportion in juvenile court referrals. The association between disproportionate patterns of school discipline and court referrals persists after controlling for poverty, urbanization, and other relevant factors. Conclusions. The implication is that school‐based programs that offer alternatives to suspension and expulsion and promote disciplinary equity may help alleviate racial disproportion in the juvenile justice system.     

Linking children's social care data to information about their care proceedings to understand the use of care proceedings and their effects on parents,children and local authorities.

Care proceedings are the most powerful child protection intervention; local authorities make applications for over 20,000 children each year in England and Wales. The Department for Education holds two administrative databases of children who receive services, for children looked after and children in need. These databases do not record the use of care proceedings. Data linkage is a powerful tool for revealing patterns not visible from a single data set; the Outcomes for children before and after care proceedings reform study linked these administrative records with a research database of care proceedings to examine children's care and service journeys associated with care proceedings. The researchers also devised a simplified method for use by local authorities with their own records and tested this with North Yorkshire County Council. Analysis of the linked data reveals how care proceedings are used and the impact of care proceedings on care demand. It provides the basis for analysis of cohorts of children subject to proceedings and feedback to social workers, children's guardians, and the judges and lawyers on their decisions and children's outcomes.
