The present study aims at systematically analyzing the findings reported in qualitative research on acculturation and psychological adjustment in the school context. Content analysis was conducted using the deductively developed and inductively enriched system of categories. The results of the study provide insights into youths’ acculturation and their psychological adjustment in the school context as well as schools’ mechanisms and strategies for responding to minority youths’ needs in the process of the cultural transition. 相似文献

Changing land use from forested environments to agricultural and/or urban spaces dramatically alters soil chemical, physical,
and biological properties and thereby influences the survivability of landscape plants installed in these areas. This site
analysis was conducted along New Hope Road, in Pickens County, SC, to develop a sustainable landscape design for the greenway
corridor to buffer future cuttings of pines and offer a variety of recreational and educational opportunities for the community.
Using a “design with nature” framework, an interdisciplinary team collaborated on a thorough observation and analysis of the
inherent qualities of the site, historical documents and aerial photographs to describe the land use history of the site.
The dominant soil series found on the site were Cecil clay loam, Cecil sandy loam, and Pacolet clay loam. Surface soil chemistry
tests were conducted to examine soil and buffer pH; organic carbon and nitrogen contents; nitrate–nitrogen; extractable phosphorus,
potassium, calcium, magnesium, zinc, manganese, copper, boron, and sodium; lime requirements and recommendations; cation exchange
capacity; acidity; and percent base saturation. Analysis of site history, aerial photographs, and soil testing revealed that
a history of intensive agricultural land use and managed forestry on the site has noticeably altered the soil quality. Severe
soil erosion and compaction brought about by a combination of anthropogenic and natural causes have left much of the site
with infertile soils lacking a true topsoil layer and characterized by low pH. These qualities present numerous challenges
when attempting to modify and install vegetation. Based on historical land use, soil analysis, and plant species characteristics,
a final landscape design was created that addressed the environmental opportunities, constraints of the site and provided
site- and plant-specific fertilizer recommendations for successful establishment and maintenance of this greenway corridor. 相似文献

This article presents material from literature and responses from national experts about social work developments in the 15 Former Soviet Union (FSU) states, since independence in 1991. Taking professionalization as a theoretical framework and considering the role of the state and other actors, the authors use a thematic approach to analyse the factors relevant to the professional project. Throughout the region, the state is identified as still the major actor in driving welfare changes and creating the organizational and legislative bases for the development of social work. A chronology of legislation relevant to the establishment of social work is included which highlights the variations in the pace of developments, as do the establishment of professional education (throughout the region) and professional associations (in most countries). The authors conclude that the professional project faces many challenges across the FSU region and the progress made – or lack of it in some countries – can be related to the politics and economics of particular states. However, the evidence suggests that, less than a quarter of a century after the demise of communism, this project has been initiated in all but one FSU countries and there are indications of positive developments. 相似文献

In the field of social sciences, certain tasks, such as the identification of typologies and the characterization of groups of individuals according to a set of questions, tend to pose a challenge for researchers. Further complications arise if the chosen rating scale is from 0 to 10, since the responses can be treated either as metric or categorical variables. This paper shows that neither treatment is able on its own to capture all the inherent properties of this type of data, and goes on to propose a bicriteria clustering approach, which captures both perspectives and enables the simultaneous analysis of mixed data using multiple tables. 相似文献

AbstractMany researchers and practitioners have long recognized the significance of measuring performance. Although general guidelines for measuring business performance are widely available, no appropriate measurement frameworks have been developed for measuring agri-food supply chain performance. Particularly, food quality and risk-related indicators have not been well integrated into existing performance measurement systems. Our research, therefore, addresses this knowledge gap by first providing an in-depth review of extant performance measurement systems and frameworks. It then develops an analytical framework by extending the Supply Chain Operations Reference (SCOR) model which has been extensively implemented across non-food industries. The analytical framework is further validated by utilizing a case study of 50 farmers and 10 dairy companies, operating in the New Zealand dairy industry.Our pilot testing and subsequent findings show that the individual metrics interlocked with the analytical framework are in-line with the key industrial practices adapted by the New Zealand dairy industry. In addition, the framework is flexible and scalable to evaluate and benchmark other agri-food supply chains – ranging from fresh products such as fruits and vegetables to processed foods such as canned fruits. The findings further show that the detailed information required for measuring the level-3 SCOR metrics is not easily available in the industry, as researchers need to access specific company records that may be confidential. Consequently, this study provides how agri-food supply chain managers can employ our new analytical framework in-conjunction with the SCOR model for a deeper understanding of the complicated performance measurement indicators applied in their agri-food production systems and relevant supply chains. 相似文献

This paper examines the gender gap in wages in Russia from 1992 to 1995. It uses data on prime aged men and women from the
Russia Longitudinal Monitoring Survey (RLMS) and focuses on those living in urban areas. Differences in hours of work appear
to explain about one half of the gender differential, but there is still a large differential in average hourly wages between
men and women. Observable differences in characteristics between men and women explain almost none of the differential or
the changes through time.

This paper analyses how native and immigrant women adapt their labour supply soon after childbirth in Switzerland. The analysis aims to examine whether the heterogeneity in post-birth female employment is explained by differences by women's origin with respect to skills composition, occupational attainment and household financial situation. Using 2010–2015 panel data from the Swiss Labour Force Survey, multinomial models focus on the transitions experienced by employed women from t?1 (one year prior) to different levels of labour-market involvement in t (reference week) after childbirth (which occurs when a woman has a child of less than one year of age in t). Three possible outcomes are considered: same/more working hours, fewer working hours, and withdrawal from employment. Double hurdle models are also used to account for the total amount of hours worked by those women who remain in employment after childbirth. In post-birth employment patterns, a larger positive effect of women's opportunity cost, measured through educational attainment and previous job characteristics, than of partners’ income, is observed, especially for immigrant women. 相似文献

Economic crisis differently impacts on the decisions of companies how to manage human resource development (HRD) initiatives. For the IT sector, intellectual capital becomes a core source of sustainable competitive advantages where HRD is seen like a tool to develop the internal stock of human capital. This article explores the approaches to HRD used by Russian IT-companies during the crisis. On the basis of the conceptual debates regarding the necessity to invest more in HRD programs even in the crisis conditions and our own empirical research, we tried to find out what happened with HRD costs during the crisis and what was the relationship between HRD costs and company’s performance during the crisis in Russian IT-companies. We conclude that Russian IT-companies perceive the value of HRD programs; hence, the most innovative-active and fast developing IT-companies prefer to constantly invest more in HRD initiatives. In crisis conditions, we recommend them to develop and implement more internal training programs. 相似文献
