New Ways to Promote Proenvironmental Behavior: Expanding and Evaluating Motives for Environmentally Responsible Behavior

This article contends that while striving to promote environmentallyresponsible behavior, we have focused attention too narrowly on just two classes of motives. There is a need to expand the range of motives available to practitioners and to provide a framework within which motives can be evaluated for both their immediate and long-term effectiveness. The article then examines a strategy for promoting environmentally responsible behavior that has significant potential. This strategy is based on a particular form of motivation called intrinsic satisfaction. Nine studies are reviewed that have outlined the structure of intrinsic satisfaction. A key theme discussed is the human inclination for competence. This fundamental human concern is shown to have both a general form and a resource-specific version.     

Similarities and Differences between Leadership and Management: High‐Performance Competencies in the British Royal Navy

This paper describes the research, analysis and development of a model clarifying the similarities and differences in competencies and personality factors 1 associated with effective Leadership and Management in the Royal Navy. A questionnaire study was conducted on a sample of 261 Officers and Ratings (Sailors). Their performance was rated through the organization's rigorous appraisal process, whilst competency and personality data were gathered through the Occupational Personality Questionnaire and the Leadership Dimensions Questionnaire. The results identify the common and unique relevance of specific competencies and personality factors and so provide an illuminating insight into the differences between the constructs of leadership and management. The critical factors related to effective leadership and management performance are also identified.     

Ethics and social media: Implications for sociolinguistics in the networked public1

As a popular agora for writing identity into being, the networked public of social media sites presents exciting and unprecedented possibilities for sociolinguistic research. At the same time, these sites raise a wealth of unfamiliar methodological and ethical issues, and debate concerning appropriate ethical measures for research targeting online discourse communities is emergent. One of the most pressing debates concerns the visibility of online interaction (i.e. its locus between the public and private ends of the continuum). Although they exist freely online, networked publics are not public forums. They are governed by both personal and communal norms, and they are networked. This combination of factors gives rise to unique ethical challenges, particularly in the case of Facebook, an accessible and data‐rich, yet problematic, research site. This paper reviews the ethical difficulties presented by Facebook, and presents a framework for ethnographic sociolinguistic research that uses this site as a source of data. En tant qu’espace public privilégié pour la création de l’identitéà travers l’écriture, le public ?réseauté? (interconnecté) des sites des médias sociaux présente des possibilités prometteuses et sans précédent pour la recherché en sociolinguistique. Cependant, ces sites soulèvent de nombreuses questions méthodologiques et éthiques qui sont nouvelles, d’où l’émergence de discussions portant sur les mesures éthiques appropriées pour la recherche qui vise les communautés discursives en ligne. Un des débats concerne la visibilité de l’interaction en ligne (c.‐à‐d. sa place entre les extrémités privée et publique du continuum). Bien qu’ils existent de façon libre en ligne, les réseaux publics ne sont pas des forums publics. Ils sont gouvernés à la fois par des normes personnelles et communautaires, et ils sont interconnectés. Cette combinaison de facteurs donne naissance à des défis éthiques uniques, en particulier dans le cas de Facebook, un site de recherche accessible et riche en données, mais problématique. Cet article passe en revue les difficultés éthiques que Facebook présente, et offre un cadre de travail pour la recherche sociolinguistique ethnographique utilisant ce site comme source de données.

Body Talk: Some Thoughts On Anorexia

In this paper, I will attempt to address questions about the dynamics of anorexia within family relationships, the ways in which anorexic thinking encapsulates itself in the mind, and how it can leave both the therapist and the family feeling ‘starved out’. I will also address some organisational issues, in the ways the therapeutic agency can come to mirror the anorexic dilemma. How does the metaphor of ‘growing’ and ‘growing up’ join with the anorexic crisis? I will discuss the cases of both a boy and a girl with anorexia, in order to think about the dynamic differences in the ‘becoming of a man’ and the ‘becoming of a woman’.     

Robust penalized logistic regression with truncated loss functions

The penalized logistic regression (PLR) is a powerful statistical tool for classification. It has been commonly used in many practical problems. Despite its success, since the loss function of the PLR is unbounded, resulting classifiers can be sensitive to outliers. To build more robust classifiers, we propose the robust PLR (RPLR) which uses truncated logistic loss functions, and suggest three schemes to estimate conditional class probabilities. Connections of the RPLR with some other existing work on robust logistic regression have been discussed. Our theoretical results indicate that the RPLR is Fisher consistent and more robust to outliers. Moreover, we develop estimated generalized approximate cross validation (EGACV) for the tuning parameter selection. Through numerical examples, we demonstrate that truncating the loss function indeed yields better performance in terms of classification accuracy and class probability estimation.     

On the Sequential Selection Problem*

Kwan and Yuan [13] considered the sequential selection problem in which an employer should arrange the sequence of interviews with job applicants to fill a position. In this note, it is shown that their selection problem would be alternately interpreted as an optimal search problem or, more specifically, a discrete search problem with a stationary target. A more generalized version of the ordering problem is proposed which explicitly considers the time value of money. Also, the optimality of the ordering strategy in the generalized problem is proven by the pair-wise exchange method, which is simpler than the induction hypothesis-based proof. The sequention selection problem is shown to be a special case of the general ordering problem where the discount rate is zero.
