Summary This paper presents an application and evaluation of competing risks analysis (Chiang, 1968) of mountain pine beetle life tables. Three known and one group of unknown risks are used. Interpretation of the results
imply that only the crude probability of death from a specific cause is applicable to this situation; net and partial crude
probabilities are yet incomplete. None of the risks (factors of mortality) exerted sufficient influence upon the population
to be considered factors of regulation or reduction. Evidence remains that the mountain pine beetle is food-regulated at optimum
temperature conditions and temperature-regulated at optimum food conditions. 相似文献

ABSTRACTEurope, in the throes of global trends, dissolves and yet re-establishes boundaries, both on its external perimeter and in terms of its internal social and political structures in a process reminiscent of the early period after the industrial revolutions. Once again it poses a fundamental question for social work: is the profession’s mandate limited to containing the effects of this process at the level of its individual victims or can it play a role in shaping European social policies which would deal with structural issues and further the cause of European integration? By examining the spaces created by the EU’s ambiguous initiatives on social issues – in areas like child welfare, poverty or migration – it will be shown that social ‘rescue’ attempts might only serve to legitimate exclusion and to further the decline of social solidarity within European states – and ultimately the disintegration of the European Union itself. The alternative lies in taking a wider political perspective and practising ‘relational citizenship’, giving people rights to belong and to participate. 相似文献

Cameron, Cameron, and Proctor (2017) have complained that Cameron and Cameron (1996) were not cited in some articles authored by this journal’s editor. As part of this editor’s policy of welcoming critiques of the editor or articles published in Marriage &; Family Review, we are pleased to respond, as part of an assignment for a graduate course in statistics and research design. Although remarkable for its time in terms of sample design, Cameron and Cameron’s (1996) research featured substantial limitations or ambiguity in sampling attrition, measurement of parental sexual orientation, and small sample size with respect to the number of children with same-sex parents. Although we cannot recall the exact reasons for which the editor neglected to cite Cameron and Cameron (1996) in more frequency or detail, there were many scientifically reasonable possibilities. Cameron et al. (2017) are welcome to respond in detail to our concerns. 相似文献

The sociology of death, dying and bereavement tends to take as its implicit frame either the nation state or a homogenous modernity. Between-nation differences in the management of death and dying are either ignored or untheorized. This article seeks to identify the factors that can explain both similarities and differences in the management of death between different modern western nations. Structural factors which affect all modern nations include urbanization and the division of labour leading to the dominance of professionals, migration, rationality and bureaucracy, information technology and the risk society. How these sociologically familiar structural features are responded to, however, depends on national histories, institutions and cultures. Historically, key transitional periods to modernity, different in different nations, necessitated particular institutional responses in the management of dying and dead bodies. Culturally, key factors include individualism versus collectivism, religion, secularization, boundary regulation, and expressivism. Global flows of death practices depend significantly on subjugated nations' perceptions of colonialism, neo-colonialism and modernity, which can lead to a dominant power's death practices being either imitated or rejected. 相似文献

Impaired communication and social interaction are symptoms central to autism spectrum disorder (ASD). Children or young people with ASD have varied intellectual ability, learning difficulty, and needs. For caregivers and health care professionals providing care to children with ASD, many challenges are encountered in everyday conversations. Enhanced knowledge of the spectrum and understanding the child or young person with ASD may improve conversation and social experiences. This article provides a practical introduction for health professionals seeking to improve their interaction with young people with ASD. Fictional vignettes, in which children with ASD are seeking care and support are presented, followed by discussion on communicating with children with ASD. 相似文献

To demonstrate the relationship between design and emotional development for kids, this article offers an initial approach about the definition and historical aspects of emotion in product development, citing the main authors of this issue. Based the field research conducted with children from 2 to 6 years of age, was also describes the basic ideas of Piaget in the child psychology and pre-operational stage (age group studied) and the significance of children's toys from the perspective of Vigostsky. Using this theoretical framework and results of field research, we can infer some emotional design as advocated by the producers of positive affect on humans and its relationship with the child's development and choices of their toys. 相似文献

Malnutrition is a major problem for rural areas of Sub-Saharan Africa. Technology such as the maize mill, which alleviates the burden of pounding grain, also introduces opportunities and new challenges for improved nutrition. While there have been many technical studies of grain mills, and maize mills are in operation in hundreds of locations throughout Sub-Saharan Africa, the maize mill has not been studied from a socio-technical system perspective. This paper reports on the first phase of a study grounded on the hypothesis that mills can improve nutrition by exploiting their function as a social gathering point and providing both instruction and enjoyable healthful products. The objective was to identify those products that could be made available that customers at the mill would be willing to buy. Following observation of food availability, preparation, and consumption preferences within daily work routines, sample products were prepared and presented for cooking and consumption, along with some discussion at a district center mill owned by a local woman. The responses of customers and the mill owner were positive. Strategies for local manufacture and distribution of these products for sale and roles of the mill owner and the mothers are questions for future study. 相似文献

AbstractIn the last decades, sustainable concerns have increasingly gained importance to organizational survival, and Lean/Six Sigma approaches are becoming more and more outstanding in order to improve sustainability performance. This article aims to evaluate the degree of importance of sustainable performance measures of Brazilian organizations and to propose guidelines to achieve sustainability by aligning these measures with operational improvement programmes. Multiple data collection methods were applied as theoretical literature review, questionnaire survey and semi-structured interviews with industry professionals and academic researchers. The findings show that it is the corporate responsibility to focus their efforts on both operational improvement programmes and sustainable initiatives in order to achieve better environmental protection, corporate reputation, quality management, cost performance and suppliers relations, as they are considered to be more important on organizational sustainability. 相似文献

The current debate on social work research methods shares some of the features of a general ‘crisis in epistemology’ evident in many academic disciplines which in turn is related to unresolved issues concerning scientific knowledge production in modernity. Social work's own attempts to develop a research basis, as its entry into modernity, shows historically a polarisation between a leaning towards positivist models as well as an affirmation of the importance of reflecting on personhood and the self in line with hermeneutic principles. It is hypothesised that political interests emanating from neoliberal social policies favour currently a positivist meaning of ‘evidence’ in practice research with implications of ‘value neutrality’ while social work practice needs to always address persons and their structural context equally. Therefore the polarisation between positivist and hermeneutic research orientations must be maintained as an impulse to acknowledge specific human qualities. Beyond implications for researcher-practitioners this perspective also contributes to a better understanding of future directions of epistemology in other disciplines. 相似文献

Building upon intensive ethnographic research on the undocumented youth movement in Los Angeles, this paper investigates the backstage work done by the leaders and activists within a movement to create cohesive and disciplined frontstage performances. These backstage techniques and strategies are important to examine because frontstage unity is not natural or automatic. As most campaigns are made up of heterogeneous individuals, organizations and groups, frontstage coherence is something that needs to be worked upon. We show that this essential backstage work consists of 1) training activists to become disciplined frontstage performers; 2) converging the feelings of activists through emotionally intensive disciplinary techniques; and 3) managing differences and conflicts in the free spaces of the movement. This paper thus aims to encourage scholars to look under the hood of public protests and give greater weight to studying the backstage work needed to produce strong and powerful voices. 相似文献
