Computational approach test for inference about several correlation coefficients: Equality and common

In this article, we consider inference about the correlation coefficients of several bivariate normal distributions. We first propose computational approach tests for testing the equality of the correlation coefficients. In fact, these approaches are parametric bootstrap tests, and simulation studies show that they perform very satisfactory, and the actual sizes of these tests are better than other existing approaches. We also present a computational approach test and a parametric bootstrap confidence interval for inference about the parameter of common correlation coefficient. At the end, all the approaches are illustrated using two real examples.     

Bootstrap approach to test the homogeneity of order restricted mean vectors when the covariance matrices are unknown

Testing homogeneity of multivariate normal mean vectors under an order restriction when the covariance matrices are unknown, arbitrary positive definite and unequal are considered. This problem of testing has been studied to some extent, for example, by Kulatunga and Sasabuchi (1984 Kulatunga, D. D. S., Sasabuchi, S. (1984). A test of homogeneity of mean vectors against multivariate isotonic alternatives. Mem Fac Sci, Kyushu Univ Ser A Mathemat 38:151–161. [Google Scholar]) when the covariance matrices are known and also Sasabuchi et al. (2003 Sasabuchi, S., Tanaka, K., Tsukamodo, T. (2003). Testing homogeneity of multivariate normal mean vectors under an order restriction when the covariance matrices are common but unknown. Annals of Statistics. 31(5):1517–1536.[Web of Science ®] , [Google Scholar]) and Sasabuchi (2007 Sasabuchi, S. (2007). More powerful tests for homogeneity of multivariate normal mean vectors under an order restriction. Sankhya 69(4):700–716. [Google Scholar]) when the covariance matrices are unknown but common. In this paper, a test statistic is proposed and because of the main advantage of the bootstrap test is that it avoids the derivation of the complex null distribution analytically, a bootstrap test statistic is derived and since the proposed test statistic is location invariance the bootstrap p-value defined logical and some steps are presented to estimate it. Our numerical studies via Monte Carlo simulation show that the proposed bootstrap test can correctly control the type I error rates. The power of the test for some of the p-dimensional normal distributions is computed by Monte Carlo simulation. Also, the null distribution of test statistic is estimated using kernel density. Finally, the bootstrap test is illustrated using a real data.     

The state and the development of an information society: Greek policy and experience

The paper looks into the dynamics of information society policy and its implementation in the Greek context. It argues that information society development is a contested process, influenced by pre‐existing state, economy and society relations. Based on this, it looks into the different aspects of the idiosyncratic path which the evolution of the Greek information society has followed, particularly after 2000. Using Bob Jessop's strategic‐relational approach (SRA) to the state as an analytical framework and drawing on a number of in‐depth interviews with relevant political actors, it provides insights into policy implementation by examining: the public management of information technology projects, how such projects were received in bureaucratic structures and practices, as well as the relationship between the state and the information and communication technology (ICT) sector in public procurement processes. The emphasis is on the period 2000–2008, during which a major operational programme on the information society in Greece was put into effect. The paper also touches upon the post‐2008 experience, suggesting that information society developments might include dynamics operating independently and even in contradiction to the state agenda.     

Evaluating social exclusion interventions in university-community partnerships

Most university-community partnerships (UCPs) involve elements of community-level social exclusion interventions. As such, they face substantial challenges in management and evaluation. This paper highlights the central challenges associated with evaluation of UCP and other social exclusion interventions at the community level, and suggests methods to overcome them. The main body of the paper presents a case study based on a four-year action research involving evaluation of a social exclusion intervention initiated and implemented by a UCP in Israel. The case study highlights the challenges faced by the evaluation team, the solutions provided, and the contribution of the evaluation to improvement and accountability.

Editorial

Undergoing a traumatic experience can be a life-changing event, having a significant impact on individuals, families, communities, workplaces and societies. Traumatology is therefore a complex field of study demanding a sophisticated level of understanding to serve as a theory base. This article explores the potential for existentialist philosophy to make an important contribution to our understanding of trauma and its effects. It presents trauma as an existential injury and explores the psychosocial basis of traumatic experience — that is, conceptualising trauma as having both psychological and sociological dimensions, the combination of which has profound existential resonances. While the theoretical ideas discussed can be applied to trauma at any stage in the life course, this paper focuses in particular on childhood trauma. Consequently, child abuse is used as an example of how trauma can have a significant (and detrimental) effect on identity development, invoking a need for a commitment to trauma recovery.     

“Either Side of Delphy Bridge”: A deep mapping project evoking and engaging the lives of older adults in rural North Cornwall

This article reports on work to date by an arts practice-led research team exploring older adults’ conceptions of, and connectivity with, the physical, social and cultural landscapes in which they locate themselves. The team is based at the Department of Art and Design, University of the West of England (UWE) and has conducted fieldwork, interviews and small-scale interactions in an area of rural North Cornwall with a view to “deep mapping” older adults’ “lived landscapes” using a variety of practical methods derived from creative arts practices, critical reflection on deep mapping, ethnographic approaches, and referencing a range of theoretical positions. The project forms part of a work package within “Grey and Pleasant Land? An interdisciplinary exploration of the connectivity of older people in rural civic society” (abbreviated below as GaPL), funded by the UK Cross-Research Council ‘New Dynamics of Ageing’ Programme. In what follows we will describe and critically discuss the fieldwork undertaken and the various ways in which the performative interactions and the creative multimedia evocations that draw on the team’s interactions with older people might extend the growing dialogue between deep mapping, visual and other innovative ethnographies, and critical gerontology.     

Integrating Existentialism and Super's Life‐Span,Life‐Space Approach

As workers face a changing and ever‐complex employment landscape, traditional career theories and approaches may not be sufficient in meeting career challenges. Calls for integrated career theories have emerged as more people seek meaning and purpose in their lives and careers. This article proposes a career counseling option that integrates existentialism and Super's (1990) life‐span, life‐space approach to establish a foundation for a broader approach to career development that views clients holistically by exploring life and career meaning and purpose from a developmental perspective. A case example and interventions are provided to demonstrate practical application and a contextual framework, along with implications for counselors.     

Barriers to Integrated Treatment of Substance Abuse and Trauma Among Women

Despite increasing empirical support for an integrated approach to treating trauma and substance abuse, many substance abuse treatment programs have been slow to embrace integrated models of practice. Using an embedded case study design, the purpose of this study was to understand barriers that prevented a substance abuse treatment provider and 20 professionals and staff from adopting an integrated approach to treating substance abuse and trauma. Data analysis revealed 2 kinds of barriers that prevented substance abuse treatment professionals from fully integrating substance abuse and trauma: systemic and professional barriers. These barriers have to be taken into account when trying to move providers and professionals toward integrated approaches to treating substance abuse and trauma.
