Traceability is normally difficult to achieve in continuous processes, since there are no natural batch structures. In this article, we demonstrate flow-based simulation using process data to improve traceability in a continuous pelletising process. Using the simulation model, the engineers could test the impacts of process disturbances, identify cause and effect relations and aid control in case of process disturbances. In a field trial where the chemistry of an additive was varied during production of a special product, the simulation forecasts predicted the level of the chemical content after the plant within the errors that the engineers found acceptable. 相似文献

Global developments in dual citizenship legislation highlight changes to conceptualizations of citizenship by increasing the focus on individual rights. Questions of inclusion and exclusion have been illuminated by the move toward wider acceptance of dual citizenship. To understand global patterns and developments in dual citizenship laws this article analyzes the legislation pertaining to dual citizenship in 115 countries. The results show how dual citizenship is becoming increasingly accepted – a development that has predominantly taken place within the last 20 years. A strong regional pattern is identified, supporting the argument that dual citizenship is spreading in a fashion similar to how the idea of citizenship expanded from Europe in the 19th and 20th centuries. Potential internal and external reasons for this development are discussed and individual countries’ experiences analyzed. 相似文献

The hurdle of Niklas Luhmann's extensive theories is their complexity and level of abstraction. These qualities are, however, exactly what constitute their empirical sensitivity to the interrelation between organization and society in today's hyper-complex society. Luhmann never theorized on public relations; yet his theories enable identification of frames for understanding public relations in interrelation to society's overall coordination processes. Contemporary society apparently tries to solve problems activated by the blind reflexivity of modernization by activating reflective forms of coordination. Correspondingly, practice ideals of public relations can be reconstructed as reflection—the specific worldview which facilitates self-insight in relation to the social context. 相似文献

Intra‐ and Inter‐generational Perspectives on Youth Participation in Sweden: A Study with Young People as Research Partners 下载免费PDF全文
In this study, intra‐ and inter‐generational perspectives on youth participation are combined and compared. Young people were invited to participate as research partners in an interactive research circle and conducted a survey about participation with other young people as respondents. The discussion concerns how an interactive methodology contributes to the understanding of the concept of participation. It is suggested that political definitions of participation be amended to include having a sense of being recognised in a communicative context, taking responsibility and share with other people one's experiences. This is based on the perspectives of young people. 相似文献

The Danish welfare system inadvertently provides a good opportunity for young creative people to pursue their dreams in creative fields such as art, acting, music while being on unemployment benefits. As Michael, one of the participants, puts it: ‘I consider unemployment benefit entrepreneurial support’. The subversive practice is illegal. This qualitative study investigates how young unemployed people who choose to be unemployed in order to engage in innovative projects in creative fields understand and justify their practice. Analysis of in-depth interviews with six young unemployed persons shows how the understanding and management of responsibility is pivotal in the self-understanding and legitimization of receiving unemployment benefits by choice, not out of need. This creative group reflects the contours of a new type of unemployed that has received very little attention in the research literature. The group challenges the traditional representation of the unemployed and portrays themselves as innovative, competent and able to cope with financial insecurity even though it is psychologically distressing and a risky path to go down. We characterize them as strategic self-managing as they use educational systems and unemployment benefit systems for something entirely different from what they are intended – they use it to create their own artistic life courses. This study tentatively points to a categorization distinguishing between personal, social and societal responsibility by which we can improve our understanding of responsibility in neoliberal contexts. 相似文献

Using weekly music charts data in 10 countries over the period 1990–2015, we analyze whether digitization leads to a trend of homogenization of music content or conversely to a greater acoustic disparity. We split the digitization era in four periods that correspond to four new emblematic distribution models (Napster, iTunes, YouTube, Spotify). Our main result is that while acoustic diversity decreased during the iTunes and the YouTube periods, the period that begins with the introduction of audio streaming services, such as Spotify, represents a turning point and is marked by a significant increase in acoustic diversity. 相似文献

We assess how the support parents provide to young adults as they leave school and begin working is related to their family’s socioeconomic circumstances. We do this using an innovative Australian data set which merges survey and administrative data. The survey data inform us about intergenerational co-residence and financial gifts and the administrative data about the family’s welfare receipt history. We find that disadvantaged young people are more likely to be economically independent of their parents than are their more advantaged peers. This disparity is larger for financial gifts than for co-residence and increases with age. Moreover, there is a complex relationship between parental support and participation in study and work. We find no evidence, however, that a lack of parental support is the source of the socioeconomic gradient in either studying or employment. These results are important in eliminating one potential pathway through which socioeconomic disadvantage limits young people’s outcomes. 相似文献

This article illustrates the differences in knowledge about HIV and AIDS and attitudes among 150 young women from three different countries (Sweden, Chile and Ecuador). In each country, 50 consecutive women, visiting a family planning clinic answered 23 structured questions. The questionnaire was translated into Spanish. The aim of this study was to evaluate the influence of age, education, ethnicity and religion on young women's knowledge of HIV and AIDS. This study shows that ethnicity is the most important independent variable influencing the level of knowledge (stepwise logistic regression). Also, in Chile and Ecuador, less than 10% of the women in the study required that their partner use a condom. In Sweden the use of condoms is often combined with another contraceptive, yet more than two thirds of the women in Sweden were unprotected from a sexually transmitted disease during coitus. 相似文献

We employ an empirical general equilibrium model of the CAP to determine which factors and countries would be expected to be opposed to or support reform of the CAP. The objective is to determine who are the “friends” and “enemies” of the CAP. The analysis studies the extent to which lobbying activity by these interested parties could be expected to encourage or discourage internal EU reform of the CAP. Several alternative policies to reform the CAP are evaluated in this manner in order to determine if one or another set of policies has a greater chance of being accepted. Specifically, we study the Uruguay Round Agreement, as well as a number of stated negotiating positions presented during the Round. The result will be a summary assessment of the relative politico-economic acceptability of these reform proposals within the EU. Our results lead to a very simple policy conclusion. Given the set of policy packages considered here, there is little doubt that the EU was most inclined to adopt a proposal incorporating compensation payments. Without further disaggregation of the analysis to identify the United States or Japan, we can only note that such a proposal is also the best as far as overall welfare goes for the rest of the world. Our results confirm the importance of sidepayments in the implementation of the Uruguay Round Agreement. 相似文献
