Knowledge, Consequences, and Experience: The Social Construction of Environmental Problems 总被引:2,自引:0,他引:2
Jerry Williams 《Sociological inquiry》1998,68(4):476-497
Perhaps one of the most obvious yet difficult questions confronting sociologists concerned with large-scale environmental problems is an epistemological one: How do we know what we know about the state of the environment? This paper explores the realist and constructionist approaches to environmental-social problems and finds both inadequate as currently formulated. A case is made for a phenomenological constructionism that moves beyond relativism and simple definitional constructionism by exploring how we actually experience the world. This approach recognizes the existence of a natural world independent of our constructions, yet suggests that our knowledge of it is always mediated, indirect, and pragmatically motivated. 相似文献

The activity of social research has been much discussed in recent years. It is examined here as a social process, with special attention to the participation of different groups of people. Four modes of doing research are identified. The framework accommodates and shows close relationships between established modes of research which generally have been seen to be substantially different. At the same time it includes modes which are more participatory in character and which have important implications for undertaking research, the development of theory, and the functioning of social groups, including society. 相似文献

Children who have been sexually abused by a ring of adults present in a way that may confuse and mislead practitioners familiar only with single-offender sexual abuse. Understanding the similarities and differences between single- and multiple-offender sexual abuse is essential in determining the validity of a child's disclosure as well as in carrying out an appropriate treatment plan. Addressing the denial and resistance within the child welfare system in relation to child sexual exploitation by a ring is crucial to a practitioner's effectiveness. Finally, developing a therapeutic parent-child relationship is critical to the families who must live with their child's experience. 相似文献

This article examines second-generation Asian Americans' explanations of the significant influences on their own religious identities. Data include interviews (N = 73) with college-aged Asian Americans from different religious traditions and ethnic backgrounds. Respondents viewed families as the most significant influence on current religiosity. Mothers and fathers were mentioned most often, followed by extended kin, siblings, and relatives, who acted as what we call "reinforcers,""substitutes," or "contrasts" to the roles that parents played in religious socialization. These roles occurred along two religious configurations within families: heterogeneous or homogeneous degrees of religious commitment and religious affiliation. Directions for future research and contributions to the religious transmission literature follow. 相似文献

Abstract Using samples of census data from the University of Minnesota Population Center's “Integrated Public Use Microdata Series” (IPUMS), we describe trends in African‐American migration to the South across recent decades, and explore the applicability of the concept of “return migration” to various demographic patterns. Our findings suggest that the return movement contains multiple migration streams involving African‐Americans of higher socio‐economic status (compared with both origin and destination populations) moving to both urban and rural destinations. These patterns represent clear differences from the earlier 20th century's “Great Migration” of African‐Americans from South to North. The recent return migration streams suggest that the South may be replacing the North as a “land of promise” for some upwardly mobile African‐Americans, and may also reflect what Carol Stack (1996) has termed a “call to home” as a motivating factor shaping recent African‐American migration to the rural South. 相似文献

In today's competitive market, demand volume and even the underlying demand distribution can change quickly for a newsvendor seller. We refer to sudden changes in demand distribution as demand shocks. When a newsvendor seller has limited demand distribution information and also experiences underlying demand shocks, the majority of existing methods for newsvendor problems may not work well since they either require demand distribution information or assume stationary demand distribution. We present a new, robust, and effective machine learning algorithm for newsvendor problems with demand shocks but without any demand distribution information. The algorithm needs only an approximate estimate of the lower and upper bounds of demand range; no other knowledge such as demand mean, variance, or distribution type is necessary. We establish the theoretical bounds that determine this machine learning algorithm's performance in handling demand shocks. Computational experiments show that this algorithm outperforms the traditional approaches in a variety of situations including large and frequent shocks of the demand mean. The method can also be used as a meta‐algorithm by incorporating other traditional approaches as experts. Working together, the original algorithm and the extended meta‐algorithm can help manufacturers and retailers better adapt their production and inventory control decisions in dynamic environments where demand information is limited and demand shocks are frequent 相似文献

Individual behavior under uncertainty is characterized using a new axiom, ordinal independence, which is a weakened form of the von Neumann-Morgenstern independence axiom It states that if two distributions share a tail in common, then this tail can be modified without altering the individual's preference between these distributions. Preference is determined by the tail on which the distributions differ. This axiom implies an appealing and simple functional form for a numerical representation of preferences. It generalizes the form of anticipated utility, and it explains some well-known forms of behavior, such as the Friedman-Savage paradox, that anticipated utility cannot. 相似文献
