In this article we examine the complex relationship between care experience, mental health and exclusion from school and how young people (YP) negotiate these different experiences and identities. The study is a secondary analysis, informed by symbolic interactionist theory, of interviews conducted with 19 care experienced YP in Scotland. Not all of the YP were excluded and not all had a formal mental health diagnosis, as such our study design allows interrogation of the contexts and relationships which not only facilitate but also disrupt pathways to exclusion. It also allows reconsideration of assumptions of vulnerability which are often applied to care experienced YP. Our findings suggest that these YP are moving beyond ‘role playing’ the identities ascribed to them and actively seek out relationships which enable them to construct alternative identities.  相似文献

Quantum algorithms are a field of growing interest within the theoretical computer science as well as the physics community. Surprisingly, although the number of researchers working on the subject is ever-increasing, the number of quantum algorithms found so far is quite small. In fact, the task of designing new quantum algorithms has been proven to be extremely difficult. In this paper we give an overview of the known quantum algorithms and briefly describe the underlying ideas. Roughly, the algorithms presented are divided into hidden subgroup type algorithms and in amplitude amplification type algorithms. While the former deal with problems of group-theoretical nature and have the promise to yield strong separations of classical and quantum algorithms, the latter have been proved to be a prolific source of algorithms in which a polynomial speed-up as compared to classical algorithms can be achieved. We also discuss quantum algorithms which do not fall under these two categories and give a survey of techniques of general interest in quantum computing such as adiabatic computing, lower bounds for quantum algorithms, and quantum interactive proofs.  相似文献

Women in middle management continue to face multiple paradoxes arising from their structural and gendered locations that add to the uncertainty of negotiating organizational life. Investigating the lived experiences of women middle managers can illuminate the constraints and paradoxes endemic to organizing, for such experiences foreground tensions at the intersection of structure, identity, agency, and power. Specifically, this contextual investigation of conversational humor explores links between organizational status, gender, and paradox. In so doing, it demonstrates how women can use humor to negotiate managerial identities and to navigate organizational life. This study uncovers nuanced and important communication tactics of middle management women. This study also reveals the value of investigating the complex convergence of humor, gender, and organizational communication theory.  相似文献

Our study compares the motivations of Australian and German book publishers. The results demonstrate remarkable similarities, but also a significant difference regarding the effects of the publishers’ self-concept. In the German case the publishers with a dominant economic orientation are more proactive than the publishers with a dominant cultural orientation. In the Australian case, this correlation does not exist. The same difference holds for the relationship between the economic orientation and extrinsic motivation. We discuss these results and examine empirical evidence and theoretical suggestions to explain the differing findings. The data stem from surveys conducted in the two countries with responses of 196 (Germany) and 54 publishers (Australia).  相似文献

ABSTRACT

Moving beyond the dominant bag-of-words approach to sentiment analysis we introduce an alternative procedure based on distributed word embeddings. The strength of word embeddings is the ability to capture similarities in word meaning. We use word embeddings as part of a supervised machine learning procedure which estimates levels of negativity in parliamentary speeches. The procedure’s accuracy is evaluated with crowdcoded training sentences; its external validity through a study of patterns of negativity in Austrian parliamentary speeches. The results show the potential of the word embeddings approach for sentiment analysis in the social sciences.  相似文献

EUROPEAN PUBLIC PERCEPTIONS OF SCIENCE   总被引:2,自引:0,他引:2  
In this paper we explore the relationships between public interestin, knowledge of, and attitudes towards science and technologyand the level of industrialization in 12 countries of the EuropeanCommunity. Using the 1989 Eurobarometer survey no 31 (N=11,678),we constructed four scales measuring interest, knowledge, generalattitudes to science, and support for EC funded science foreach of the 12 EC countries. We found that overall factual scientificknowledge correlates moderately positively with interest andattitudes to science. For example the Netherlands and GreatBritain have relatively high levels of knowledge, interest,and support for science in general. Spain and Greece have relativelylow levels of knowledge, interest, and support for science ingeneral. However, the simple correlation hides more complexrelationships. First, the variance within and across countriesof knowledge, attitudes and interest increases with nationallevels of knowledge. This indicates greater degrees of polarizationof both support and interest. Second, the data indicates a post-industrialismeffect: knowledge, interest in, and attitudes to science showa curvilinear relationship with levels of industrialization.The decline of interest in science and the less positive attitudesin highly developed countries requires further exploration.Third, we found, that the consistency of the knowledge and theattitude measures declines as the national level of knowledgeincreases. We suggest that this reflects a knowledge-ignoranceparadox and knowledge specialization among informed populations.Support for EC level science follows a different pattern. Wefound that France, Italy, and Spain show high levels of supportfor EC level science. This is not the case in Great Britainand Germany. The pattern suggests that attitudes towards ECscience are formed on the basis of national level scientificstrength: if the national science base is strong, EC scienceinitiatives find less support and vice versa. These findingsrepresent a first step towards a comparative assessment of publicunderstanding of science in EC countries.  相似文献
