The effect of corporate governance on sustainability disclosure

Drawing on stakeholder theory, this paper examines the relationship of board composition, leadership and structure on sustainability disclosure. We discuss that good corporate governance and sustainability disclosure can be seen as complementary mechanisms of legitimacy that companies may use to dialogue with stakeholders. Specifically we claim that, as disclosure policies emanate from the board of directors, sustainability disclosure may be a function of the board attributes: we investigate the relationship between different characteristics of the board and sustainability disclosures among US and European companies. Our results show that in order to explain the effect of board composition on sustainability disclosure we need to go beyond the narrow and traditional distinction between insider and independent directors, focusing on the specific characteristics of each director.     

Application of an Irt Polytomous Model for Measuring Health Related Quality of Life

Background: The Item Response Theory (IRT) has advantages for measuring Health Related Quality of Life (HRQOL) as opposed to the Classical Tests Theory (CTT). Objectives: To present the results of the application of a polytomous model based on IRT, specifically, the Rating Scale Model (RSM), to measure HRQOL with the EORTC QLQ-C30. Methods: 103 terminal cancer patients cared for by the home services of the Servicio Andaluz de Salud (Andalusian Health Service) (Andalusia, Spain) participated. These patients responded to the adapted Spanish version of the EORTC QLQ-C30. The application was carried out individually in the patients’ homes. Results: The results show that there is an adequate global fit between the data and the IRT model applied. The analysis of the items shows that for 31 of the 33 items there is a good fit. The items which measure the general perception of health and the perception of quality of life present a lack of fit. The study of the response categories of the items (by means of Category Probability Curves) indicates that all the alternatives work extremely well. Conclusions:The EORTC QLQ-C30 presents good metric qualities, under the RSM, ratifying the feasibility to measure HRQOL already shown in other studies carried out with CTT.     

Critical success factors in managing modular production design: Six company case studies in Hong Kong, China, and Singapore

Many researchers have explored the advantages of modular product design, its design methods and its effects on product performance. Modular design is, for example, required for product platform, mass customization and postponement in order to achieve greater product variety and differentiation. However, a few empirical studies explicitly examine how to coordinate modular product design in a managerial way. This paper addresses it by conducting multiple case studies with six companies which have successfully adopted modular product design for five years. Seven critical factors are explored in the management of modular product design. These are pre-defined product advantage, selectively used design rules, module definition, system integration, technological newness, internal communication, and supplier and customer involvement. While most of the literature studies the technical dimension of modular design within a firm, this study focuses on the managerial side across the supply chain. It gives new insights on how to manage modular product design and proposes future research opportunities.     

Hazards of neoliberalism: delayed electric power restoration after Hurricane Ike

This case study explores how neoliberal policies shape the impacts of a natural disaster. We investigate the reactions to major damages to the electric power system and the restoration of power in the wake of Hurricane Ike, which devastated the Houston, Texas, metropolitan area in September 2008. We argue that the neoliberal policy agenda insured a minimalist approach to the crisis and generated dissatisfaction among many residents. The short-term profitability imperative shifted reconstruction costs to consumers, and prevented efforts to upgrade the electric power infrastructure to prepare for future disasters. We illustrate the serious obstacles for disaster mitigation and recovery posed by neoliberal policies that privatize public goods and socialize private costs. Neoliberalism neither addresses the needs of a highly stratified public nor their long-term interests and safety.     

Affective and Cognitive Correlates of Gambling Behavior in University Students

The purpose of the following study was to explore certain affective and cognitive components and their relationships to gambling behavior in an undergraduate population. Specifically, the aim was to predict gambling severity using depression scores on the BDI-II, the dependency and self-criticism subscales on the DEQ, emotional awareness scores on the LEAS, cognitive flexibility scores from the STROOP, and a creativity subtests from the TTCT. Participants were 200 undergraduate students and 3.5–7.5% of individuals reported some level of problematic gambling behavior. Multiple regression analysis indicated that self-criticism and creative originality were significant predictors of gambling behavior, explaining 7.6% of the variance. Further analyses reveal a non-linear trend in the creative originality of those who gamble; only the at-risk gamblers were high in creativity whereas abstainers and problematic gamblers display similarly lower levels of creativity. Results are discussed in regards to Blaszczynski and Nower’s Addiction 97:487–499 (2002) subtypes of gambling vulnerability.     

A sequential design for a clinical trial with a linear prognostic factor

We study a randomized adaptive design to assign one of the L$L$ treatments to patients who arrive sequentially by means of an urn model. At each stage n$n$, a reward is distributed between treatments. The treatment applied is rewarded according to its response, 0?_Yn?1$0?Y_n?1$, and 1-_Yn$1-Y_n$ is distributed among the other treatments according to their performance until stage n-1$n-1$. Patients can be classified in K+1$K+1$ levels and we assume that the effect of this level in the response to the treatments is linear. We study the asymptotic behavior of the design when the ordinary least square estimators are used as a measure of performance until stage n-1$n-1$.     

EXTERNAL AIDS FOR SOCIAL MEMORY

Collective or social memories are not just a way for accumulating and preserving but also for sharing and developing knowledge. Indeed, as knowledge is made explicit and elaborated by a community, it enriches the local culture and the current practices, becoming a basis for communication and learning. This paper addresses the concept of 'social memory' in a specific 'community of practice': teachers and students of primary schools. The work is developed within HIPS1 (Hyper Interaction within Physical Space), a three-year (1997-2000) research project funded by the European Commission within the I 3 (I-Cube) Programme. HIPS is a hand-held location-aware tourist guide that delivers information related to the surrounding space mainly reacting to the physical movements of visitors (Benelli et al . 1999). The guide is designed to minimize the boundary between the physical space and the related information through a number of situated and contextual-aware interaction mechanisms. In the paper we present a specific application of HIPS as tool to support the creation of a social memory. First, we illustrate the theoretical framework, the cultural psychology (Vygotsky 1978), which we adopted to design the tool as an external aid for social memory. Afterwards we describe the user study and the design process that resulted in the development of an early prototype. The conclusions are a reflection about the use of new technology to open new learning opportunities for students.     

Land,territory and commons: voices and visions from the struggles

ABSTRACT

All over the world, financial capitalism and extractivism are appropriating land as if it was nothing more than a commodity, a mere ‘factor’ of production that can be exploited to generate financial returns. Movements and activists are organizing, resisting, protecting and promoting life-giving visions against this continuous enclosure of living beings and paces: they use their bodies, laws, educational projects, histories and visions to regain control over territory as a political space, self-determine and create solidarities. In the act resistance, they are the target of moral, physical and legal violence. They and their ideas are criminalized, disciplined, punished and in some cases exterminated. In this contribution, activists from the Basque Country, Guatemala, Kenya and the Six Nations and a group of academics get together to learn from each other, support the ongoing search for common vocabularies and identify possible milestones of a coordinated and international strategy for a life-enhancing future.     

Racialisation and racial formation in urban spaces*

ABSTRACT

In this paper, I try to clarify the notions of racialisation and racial formation and how they operate in the framework of nation states like Brazil. My main argument is that these processes are always constrained by the formation of social classes and national cultural repertoires even if transnational forces are important in nurturing them. I conclude by making a preliminary effort to unravel mechanisms and institutions which allow these processes of racialisation and racial formation to form part of the daily lives of black Brazilians in the context of class-structured urban spaces.
