This paper presents briefly the results of an empirical study on long-range forecasting conducted in large French corporations. It demonstrates that forecasting differs quite widely according to its technical, economic or social nature. 相似文献

This article attempts to contribute to the historically relevant debate about the role of social work in poverty situations, focusing on the emblematic and radical question whether the poor actually need social work. In the context of the currently dominant policy framework in European welfare states, that is underpinned by the emerging paradigm of social investment, we argue that it is extremely relevant to readdress this question. Within this development, the eradication of child poverty has been considered a key target of poverty reduction strategies and child and family social work has consequently been assigned a pivotal role in the fight against the intergenerational transmission of poverty. We demonstrate that the rhetoric of social investment has found a practical implementation in social work constructing the problem of poverty in terms of education and activation of both the child and the individual parent. Based on an extensive review of literature, we discuss underlying assumptions, consequences and pitfalls of the paradigm of social investment for social work and tease out whether, and on which conditions, poor families need child and family social work. 相似文献

Conventional approaches to knowledge-based system (KBS) development are not appropriate for building KBSs when the application task is structurable (i.e., exhibits a certain degree of ill structure). Building a KBS for structurable tasks requires an understanding of the problem-solving strategies used by an expert to manage the ill structure, while at the same time relying on domain theories to understand the structured parts of the task. This paper presents a methodology for developing a knowledge model for structurable tasks during the conceptualization stage of KBS development. This is equivalent to building a logical model for design during the development of conventional information systems. The methodology relies on prior research on the decomposition and characterization of a task based on its various attributes. The paper also illustrates the use of the methodology in the case of KBS development for financial hedging. The paper concludes with some observations about the potential impact of this methodology on other stages in the KBS development process. 相似文献

Child‐to‐mother violence is an area of family violence that has received limited attention over the past 20 years but is a problem for many families. It is poorly understood in the community and this lack of understanding creates a basis for families and service providers to minimize the abused mothers' experience. This paper is drawn from a larger study that aimed to explore child‐to‐mother violence in a high‐risk geographical area and describes a qualitative theme developed from 185 participating women's narratives, ‘Living in the red zone’: the experience of child‐to‐mother violence. The red zone refers to danger and was an element throughout women's narratives. It is clear from the reflections of these women that child‐to‐mother violence is a significant and complex issue. Mothers were predominantly struggling in silence with their experiences of a child or children whose behaviour was threatening and/or abusive. Their experiences were most often minimized and/or devalued by family and community members, which may prevent affected women from seeking support. Mothers generally had limited concepts of the possibilities open to them to improve their situation, or limited access to appropriate and empathic individuals or services. 相似文献

Investigations of urbanization effects on birds have focused mainly on breeding traits expressed after the nest-building stage (e.g. first-egg date, clutch size, breeding success, and offspring characteristics). Urban studies largely ignored how and why the aspects of nest building might be associated with the degree of urbanization. As urban environments are expected to present novel environmental changes relative to rural environments, it is important to evaluate how nest-building behavior is impacted by vegetation modifications associated with urbanization. To examine nest design in a Mediterranean city environment, we allowed urban great tits (Parus major) to breed in nest boxes in areas that differed in local vegetation cover. We found that different measures of nest size or mass were not associated with vegetation cover. In particular, nests located adjacent to streets with lower vegetation cover were not smaller or lighter than nests in parks with higher vegetation cover. Nests adjacent to streets contained more pine needles than nests in parks. In addition, in nests adjacent to streets, nests from boxes attached to pine trees contained more pine needles than nests from boxes attached to other trees. We suggest that urban-related alterations in vegetation cover do not directly impose physical limits on nest size in species that are opportunistic in the selection of nesting material. However, nest composition as reflected in the use of pine needles was clearly affected by habitat type and the planted tree species present, which implies that rapid habitat change impacts nest composition. We do not exclude that urbanization might impact other aspects of nest building behaviour not covered in our study (e.g. costs of searching for nest material), and that the strengths of the associations between urbanization and nest structures might differ among study populations or species. 相似文献

This study explores adolescents’ perceptions of applications used for sexting, the motives for engaging in sexting, and the consequences they relate to sexting behavior. We conducted 11 same-sex focus groups among 57 adolescents (66.67% females; n?=?38) between 15 and 18 years old in Flanders, Belgium. The analysis revealed that sexting mostly occurs through smartphone applications, such as Snapchat, which are perceived to be a more intimate form of communication than other digital applications, such as social networking sites. Both female and male respondents observed that girls might sometimes feel pressured to engage in sexting. They did so mostly out of fear that otherwise they would lose their boyfriends. Female and male respondents mentioned three main ways in which sexting photographs could be abused: (1) they could be used to coerce or to blackmail the victim, (2) they could be distributed out of revenge after the breakup of a romantic relationship, or (3) they could be forwarded or shown to peers in order to boast about having received the digital photograph. Anecdotes, which illustrate our findings, are included in the results. Suggestions for future research and implications for practice are discussed. 相似文献

Drawing on data from a large-scale international study [PIDOP – Processes Influencing Democratic Ownership and Participation. 2009–2012. Accessed August 10. http://www.fahs.surrey.ac.uk/pidop/index.htm], the present research examined psychological and demographic factors related to civic and political participation among adolescents and young adults (from 16 to 26 years of age) with a Turkish origin and residing in Belgium (n?=?153), Germany (n?=?204) and Turkey (n?=?253). MANCOVA and one-way ANOVA were employed to address how types of civic, direct and online participation differ by socio-demographic variables. The results indicate that citizenship status was not related with the types of participation, while age, gender and country were significantly related with the type of participation in various degrees. Interaction between all the variables showed that older (20–26), foreign national, male Turkish German sample is significantly more involved in civic participation activities. Results are discussed in light of the naturalization processes of migrant groups abroad and extensive religious involvement of Turkish German sample. 相似文献
