This article addresses theoretical issues concerning differentiation and class formation using North American data. It explores how socio‐economic characteristics vary and impact survival in agriculture. The study is based on panel data collected from a sample of smallholders in three Piedmont North Carolina counties. Factor analysis reveals five major dimensions of differentiation: scale, household labour, off‐farm family labour and income, demographic characteristics, and land tenure. An index of propensity to survive in agriculture, constructed from three waves of panel data is regressed upon five indices measuring the underlying dimensions of differentiation. Land tenure manifests a statistically significant net effect on survival in agriculture. These empirical results support theoretical arguments in favour of integrating analyses of socio‐economic and demographic differentiation in the study of agricultural enterprises.  相似文献

We study the quality of disclosure and the level of accountability of Italian museums using MPADI2 index (Wei et al. 2008; Botes et al. 2013) on a sample of 13 annual reports which, given the legal status of some entities, encompasses the activity of 93 Italian public and private museums, many of which are within the most visited in Italy and worldwide. The results allow for an international comparison with the annual reports of a panel of USA, UK and European museums which have undergone the same MPADI2 analysis, giving an interesting insight about museum different disclosing practices across countries.  相似文献

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.  相似文献

In the present studies, we aimed to show that the perceived procedural fairness of societal actors’ multicultural decisions promotes ethnic minority members’ societal identification. These enhanced identification levels, in turn, contribute to better psychological health and well-being. Firstly, a vignette study in a sample of African Americans explored the effect of procedural fairness climate on identification. The second and third studies used self-report questionnaires. Study 2 consisted of a sample of sojourners in a university context, Study 3 analyzed online data through an African American sample. The studies provided evidence for the effect of procedural fairness climate on increased societal identification, which in turn mediates the fairness effect on increased well-being and psychological health. Societal actors can use procedural fairness to increase well-being when making decisions that involve ethnic minorities.

The New Zealand Government's Performance Improvement Framework (PIF) is aimed at public sector organisational improvement. The PIF exemplifies how the characteristics of new public management (NPM) challenge the evolution of performance systems attempting to go beyond performance management. The paper provides an empirical example of the operation of the PIF, using a theoretical frame derived from the literature. The analysis suggests that the PIF design does not yet mitigate the effects of gaming, synecdoche, and reputation-protecting behaviour. The common graded ratings continue to hold the attention of those to whom the PIF is important, acting as a proxy for the whole performance of the organisation. This is a case study of how, despite promising adaptations, performance improvement efforts remain hampered by NPM limitations.  相似文献

  • In a time of profound national challenge and change, it is important to promote a new definition of active citizenship locally, nationally and globally. As the effects of economic, political and social globalization continue to underscore interdependence, the imperative of fostering democratic minds among a citizenry is evermore important. It is essential to conceive a common future that encourages the participation of all American citizens; inviting diversity as an asset and broadly reawakening the call to leverage the rich potentials of pluralism in search of common solutions. However, many schools are retreating from basic civics lessons and are not teaching students how to become active citizens. More importantly, public institutions overall do not appear to be advancing the fundamental awareness and skills required for sifting through political hucksterism, opinion masquerading as news and political spin. It is essential for our schools and public institutions to teach the responsibilities and joy of active citizenship. To meet the challenges of democratic cooperation and social cohesion, leaders and citizens alike should be taught and encouraged to openly question, to critique and even to criticize the status quo. The means for cultivating and institutionalizing such habits on a broad scale involves educational reformation and initiatives in civics and citizenship education to increase opportunities for meaningful public engagement. These are by no means the only answer, but they are a critical component for meeting the challenges of truly inclusive and active representative democracy where out of many, we are one.

This article describes the place of Women's and Gender Studies programmes in Australian universities as a way of thinking about the place of feminism in the academy. It begins with a story of one such small programme at a time of stress and locates this story in an account of change in Australian universities over the last 20-plus years. The narrative traces a contradictory domain in which women, feminist scholarship and Women's and Gender Studies are enmeshed. The article draws on feminist literature about Australian universities to argue that while neo-liberal university environments are clearly places where masculinist values prevail, the flows of power around individual Women's and Gender Studies programmes cannot be simply predicted. Women's and Gender Studies programmes are thriving in some universities (on a small scale). As well as institutional imperatives Women's and Gender Studies programmes are engaged by specific intellectual challenges and some of these are sketched with reference to the Australian context. Asserting the need for dedicated research and teaching that focuses on gender, the article concludes that Women's and Gender Studies programmes in Australian universities are energetic places for this to occur. It proposes an ambivalent optimism to describe its assessment of these programmes and their viability as future places of work for feminist scholars.  相似文献
