Air pollution and depressive symptomatology: Exploratory analyses of intervening psychosocial factors

Exploratory modelling revealed associations of individual perceptions, social factors, and physical components of air pollution with depressive symptomatology. Residents of the Los Angeles Metropolitan Area who have experienced a recent, undesirable life event and who perceive poor air quality in their neighborhood have greater symptoms of depression. These effects control for socioeconomic status and prior psychological status. In addition we show that perceived air quality is a function of both toxic components of ambient air as well as individual psychosocial experiences.This research was supported by the National Institute for Mental Health (MH 28924-10A1) and the Southern California Edison Health Effects Research Laboratory (J-1909902).

Committing Canadian Sociology: Developing a Canadian Sociology and a Sociology of Canada

This paper is a slightly revised version of the author's “Outstanding Career Award Lecture” presented at the Annual Meeting of the Canadian Sociological Association in Victoria, British Columbia on June 6, 2013. The paper distinguishes between Canadian Sociology and the Sociology of Canada. The former involves the explanatory stance that one takes to understanding Canada. The latter addresses the significant social dimensions that underlie Canadian social organization, culture, and behavior. I make a case for a Canadian Sociology that focuses on the unique features of Canadian society rather than adopting a comparative perspective. I also argue that there is a continuing need within the Sociology of Canada to address the issues of staples development. However, I argue that “new” staples analysis must have a directional change from that of the past, in that social processes now largely determine the pattern of staples development. Moreover, new staples analysis must include issues that were never part of earlier staples analysis, such as issues of environmental impacts and of staples depletion under conditions, such as climate change. The paper concludes by analyzing four factors that provide the dominant social contexts for analyzing modern staples development: (1) the rise of neoliberal government, (2) the implementation of globalization and its social consequences, (3) the assumption of aboriginal rights and entitlement, and (4) the rise of environmentalism. These factors were generally not considered in earlier staples approaches. They are critical to understanding the role of staples development and its impact on Canada in the present time. Cet article est une version quelque peu révisé du cours pour le “prix pour contributions exceptionnelles” de l'auteur, présenté à la réunion annuelle de la Société Canadienne de Sociologie à Victoria, Colombie‐Britannique le 6 juin 2013. Cet article ce distingue entre la sociologie canadienne et la sociologie du Canada. Le premier ce concerne la position explicative que l'on prend pour comprendre le Canada. Le dernier adresse les importantes dimensions sociales qui sous‐tendent l'organisation sociale, culturelle et comportementale. Je soutiendrai une sociologie canadienne qui se concentre sur les aspects uniques de la société canadienne au lieu d'adopter une perspective comparative. Je soutiendrai aussi qu'il existe un besoin continu au sein de la sociologie du Canada pour adresser les questions de la théorie des principales ressources. Cependant, je soutiens que l'analyse des principales ressources “nouvelle” nécessite un changement de direction que celles du passé, en ce que les processus sociaux déterminent principalement le système de développement des principales ressources. De plus, l'analyse des principales ressources “nouveau” doit inclure les problèmes qui n’étaient jamais partis des analyses précédentes, comme les problèmes d'impacts environnementaux et de la diminution des principales ressources dans les conditions comme celui des changements climatiques. Cet article ce termine par scruter quatre facteurs qui produisent le contexte social dominant dans les analyses du développement des principales ressources moderne: (1) la croissance du gouvernement néolibéral; (2) l'implémentation de la globalisation et ses conséquences sociales ; (3) l'assomption des droits autochtones, et (4) l'ascension d'environnementalisme. Ces facteurs n'ont été généralement pas considérés dans les méthodes d'analyse des principales ressources antérieures. Ils sont cruciaux pour comprendre le rôle du développement des principales ressources et leurs impacts contemporains sur le Canada.     

欧洲计算机相关发明的专利性问题：法律和经济方面的讨论

计算机软件的专利性在世界各地特别是欧洲引起了广泛的讨论。讨论分为法律和经济两个相时独立的层面：前者主要涉及对“软件本身不具有专利性”的理解以及软件专利的技术性要求；经济层面的讨论重点为专利制度时软件业特别是开源软件业的意义。在这场争论中,欧洲专利局和德国的专家学者各抒己见。法律与经济方面的讨论都往往忽视了对方的特点和视角。因此二者的融合将是大有裨益的。     

Levels of significance of some two-sample tests wkem observations are from compound normal distributions

This paper presents an investigation of the behavior of the levels of significance of the two-sample t and its related tests and the Mann-Whitney test when the samples are randomly drawn from mixtures of two normal populations (compound normals) and when the sample sizes are small (combined sample sizes ? 15). The use of the compound normal allows for investigation when the underlying populations are unequal, nonnormal, heterogeneous in variances, unimodal or bimodal, possessing smaller than normal kurtosis or containing contamination. The exact distribution of the t and its related tests are given. However, they are not readily amenable to calculations. Most of the numerical results presented were obtained by simulations     

“A 30% Chance of Rain Tomorrow”: How Does the Public Understand Probabilistic Weather Forecasts?

The weather forecast says that there is a "30% chance of rain," and we think we understand what it means. This quantitative statement is assumed to be unambiguous and to convey more information than does a qualitative statement like "It might rain tomorrow." Because the forecast is expressed as a single-event probability, however, it does not specify the class of events it refers to. Therefore, even numerical probabilities can be interpreted by members of the public in multiple, mutually contradictory ways. To find out whether the same statement about rain probability evokes various interpretations, we randomly surveyed pedestrians in five metropolises located in countries that have had different degrees of exposure to probabilistic forecasts--Amsterdam, Athens, Berlin, Milan, and New York. They were asked what a "30% chance of rain tomorrow" means both in a multiple-choice and a free-response format. Only in New York did a majority of them supply the standard meteorological interpretation, namely, that when the weather conditions are like today, in 3 out of 10 cases there will be (at least a trace of) rain the next day. In each of the European cities, this alternative was judged as the least appropriate. The preferred interpretation in Europe was that it will rain tomorrow "30% of the time," followed by "in 30% of the area." To improve risk communication with the public, experts need to specify the reference class, that is, the class of events to which a single-event probability refers.     

Multiple Attribute Decision Making with Inexact Value-Function Assessment

A major issue in value-function assessment is the possibility of receiving an indefinite response from a decision maker to a question about preferences. The conventional treatment requires a single, definite response from the decision maker. This approach either assumes that response error is zero or accepts the final solution as only approximate, without knowing how approximate it might be. In this paper we examine the issue of indefinite responses, define it more precisely, and present a method for incorporating it into decision making. The method is adaptive in that it is iterative and interactive with the decision maker who, at each iteration, is provided with information regarding the potential advantage of answering more trade-off questions and/or answering questions more carefully to reduce response error. In contrast to other approaches that “force” rationality and decisiveness, we work with irrationality and indecisiveness on the part of the decision maker. The method is demonstrated for the case of concave, increasing value functions.
