Optimal designs for asymmetrical factorial paired comparison experiments

Three forms of a general null hypothesis Ho on the factorial parameters of a general asymmetrical factorial paired comparison experiment are considered. A class of partially balanced designscorresponding to each form of H₀ is constructed and the A,D and ioptimal design, minimizing the trace, determinant and largest eigenvalue of a defined covariance matrix of related maximumlikelihoodestimators, in that class is determined. Moreover, the optimal design in each class maximizes the noncentrality parameter λ² of the asymptotic noncentral chi-square distribution of the likelihood ratiostatistic -2 log λ for testing H_o under defined local alternatives. These results apply directly to symmetrical factorial paired comparison experiments as special casesExamples are given forillustrating applications of the developed results     

The Integration of Tradition and Modernity: A Search for an Urban and Architectural Identity in Arriyadh, The Capital of Saudi Arabia

About 40 years ago, traditional villages, towns and cities of the Arabian Peninsula started to lose their regional characteristics and embody modern forms and shapes. Since then, these characteristics have been subject to dilution due to social and cultural changes as well as institutionalized changes imposed by planning and architectural practices. This process creates debates and clashes between tradition and modernity. Projects carried out since 1975 are the least representative of the regional characteristics but do attempt to have urban and architectural identity. This paper argues that all the actors in “design formulation” (clients, architects, urban designers and planners) are trying to use historic elements in the creation of architectural identities. In fact they are making efforts to create urban and architectural identity to substitute regional characters. These attitudes flourished as a result of dynamic cultural, economic, political and ritualistic influences. This paper highlights the importance of urban and architectural identity in architectural and urban projects in Arriyadh, the capital city of Saudi Arabia because such projects create precedents for other Saudi villages, towns and cities. The study identifies the forces behind the initiation, transformation and evolution of the urban and architectural identity and attempts to supplement scholarship in the fields of architecture, urban design, and planning with regard to the role of identity as a tool for improving the spatial quality of the built environment. Architectural identity participates in setting up meaningful schemata which influences human behavior as a cultural process. The paper supports the concern for search for historic symbols which may influence the architectural identity and the quality of perceived environment during the design process of new or transformed physical environments. The paper views the traditional part of the city as an amalgamation of history and economic interests and its symbolic importance seems to be a perfect place for the emergence of different forms of engagement between tradition and modernity. The importance of the traditional part is unique while the importance of continuity of tradition is very likely complementary.     

Autism self-advocacy in the Netherlands: past,present and future

This article presents the results of participatory research into the roles and practices of autistic self-advocates in the Netherlands, and the outcomes of their activities. The article discusses the history of Dutch autism self-advocacy, situating it within the history and practices of self-advocacy internationally and the socio-cultural context of the Netherlands. Particular reference is made to Judi Chamberlin’s model for building effective self-advocacy organisations. Key findings include the scope of significant achievements, and the identification of barriers to efficacy in the areas of governance, personal and organisational capacity, relationships with other organisations, and coalition-building. The research concludes by considering what practices could serve to build increased capacity and efficacy, based on the experiences of these and other self-advocates.     

Systematic review of primary prevention human papillomavirus interventions targeting college students

ABSTRACT. Objectives: The purpose of this research was to systematically analyze human papillomavirus (HPV) interventions targeting college students. Methods: Completed interventions targeting general HPV prevention, HPV vaccine uptake, or antecedents of HPV vaccination uptake that used any quantitative design, published from January 2000 to January 2014 in the English language, were reviewed. Results: Twelve interventions met the criteria. Ten interventions produced 1 or more significant outcomes on primary or secondary variables of interest. Conclusions: Efficacy of interventions can be enhanced through tailoring materials and pretesting by sex, operationalizing theories, incorporating process evaluations, employing HPV vaccine uptake outcome measures, and utilizing Web-based delivery of programs.     

The architectural form and landscape as a harmonic entity in the vernacular settlements of Southwestern Saudi Arabia

The paper aims to describe the architectural form and landscape as a harmonic entity in vernacular settlements of southwestern Saudi Arabia. The qualities of vernacular settlements and their integration and responsiveness to the physical, social, economic and cultural environment are demonstrated in this study. The socio-economic activities and customs in southwestern Saudi Arabia are presented as part of the historical process. The paper looks at the major elements of the vernacular villages and landscape as cultural-specific images. While appreciating this, the author laments the way this harmony has been disrupted not least aesthetically as a consequence of modernism which had an impetus on changing life style and social expectation. The cultural-specific images involve direct relationships between the architectural and urban forms as systems and events that are taking place in or around that form. One thesis is that each element of the vernacular village and landscape is linked to an image that shapes and influences human behavior and appreciation, thereby helping to shape larger environmental patterns. Beyond the meaning that specific elements inherit, they have functional and economic values. As a result, their visual qualities are believed to be effective in enhancing behavior through their visual attributes. One of the most important conclusions is that, there are many features of modern village extensions and landscape elements that enhance the interaction with the physical environment that ordinary citizens value, and there are elements of the vernacular villages and landscape that people regret to lose, such as ‘qasabahs', weekly markets, cultivation of terraces, etc. This is inspite of today's, modern planning and design techniques that are being sought to produce new architectural forms and landscape elements. Any attempt to substitute vernacular forms without taking into account the values that the older forms held is considered a failure of adopted modernist attitudes.     

Minority Stress in the Lives of Men Who Have Sex With Men in Cape Town,South Africa

The mental health outcomes of men who have sex with men (MSM) living in sub-Saharan Africa are understudied, despite evidence that discrimination and stigma are widespread. This article examines the occurrence and mental health effects of minority stress in a sample of diverse South African MSM. Twenty-two MSM living in Cape Town took part in exploratory qualitative in-depth interviews and completed mental health questionnaires. Results indicate that the majority of participants experienced minority stress, which affected their sexual relationships and coping strategies. Concealment behaviors and perceived discrimination levels were high and were associated with race, religion, SES, and geographical location.     

Energy Policy and Environmental Possibilities: Biofuels and Key Protagonists of Ecological Change*

While a growing body of research indicates the severe ecological and social costs of biofuel production worldwide, the U.S. government continues to promote the expansion of this fuel sector. Recent congressional testimony regarding the promotion of biofuels via the renewable fuel standard (RFS) offers a strategic research site for sociological investigation into the practices of key political actors and their roles in promoting and discouraging ecologically oriented change. Congressional hearings provide a window into the political process of energy policy formation, thus informing environmental sociological theory and debates. The ecological modernization perspective and its assumptions provide the analytical frame of this empirical analysis of congressional hearings during the peak legislative period concerning biofuels. This research is intended to contribute to alternative energy debates, add to our understanding of the role of various actors in energy policy formation, and further theoretical developments within sociology.     

Governing the Circular Economy in the City: Local Planning Practice in London

ABSTRACT

There is interest in the circular economy as a framework for transition from a linear take-make-dispose model of production and consumption, to a circular model which decouples economic growth from resource consumption. However, there is limited understanding of how that applies to the city through governance lens. This paper examines evidence from 28 municipalities in London to unpack the ‘government’ and ‘governance’ of circular economy in the city. It examines the ‘governmentality’ of circular economy in planning practice and reflects on what austerity localism and scalar politics might mean for the planning and governance of circular economy in cities.
