Au cœur du processus de construction de l'économie de la connaissance, les diasporas sont considérées comme des leviers du développement. Ainsi, on observe un intérêt grandissant de la part des gouvernements et des organisations internationales pour la production et la mobilisation des Diaspora Knowledge Networks. Dans le même temps, les associations de migrants sont de plus en plus nombreuses et l'émigration qualifiée en Amérique Latine atteint des sommets. En partant de ce constat, cette thèse a eu pour but d'observer les dynamiques de circulation du savoir entre l'Europe et les pays andins. Alors, cette thèse se construit autour de l'idée du partage de l'espace diasporique entre la société civile, les administrations des pays d'origine et pays de destination. La thèse consiste donc à montrer comment les modes de spatialisation diffèrent selon que l'on étudie une initiative systémique ou par le bas. Ainsi, en bénéficiant des expériences andines et européennes, à partir des organisations de la société civile, cette thèse révèle le partage des diasporas par, et entre, ses acteurs. / In the knowledge based economy building process, diasporas are seen as a development enabler. Thus we observe a growing interest of governments and international organizations in promoting and mobilizing diasporas knowledge networks, allowing them to contribute to national research and development activities in their countries of origin. In the mean time, diaspora organizations are growing and emigration of highly qualified at the highest rates ever reached in South America. Considering this situation as a starting point, this thesis was dedicated to observe dynamics of knowledge circulations between Europe and the Andean countries. In so doing, this thesis makes its point showing how the civil society, the origin countries and destination countries administrations share the diasporic space undertsood as the space of knowledge circulations. From this perspective we show that spatialization modes are different between systemic or spontanous initiatives. Thus, benefiting from andean and european experiences among civil society organizations we state that diasporas are both shared and split by their actors.

The purpose of this thesis is to analyze the process of internal migration in Peoples' Republic of China. It focuses on low-skilled rural migrant workers, their overall characteristics, role in the economy and their status within Chinese society. This analysis aims to prove that despite the fact that rural migrants represent an essential element of Chinese economy, and have contributed by a great deal to China's economic take-off, they are still a very discriminated group of Chinese society and are constantly facing violations of their rights.

A role description for a medical coordinator in extended and long term care facilities in British Columbia has been defined using a Delphi method. Also obtained during the study was a long term care philosophy. Three groups - nurses, administrators, and physicians took part in three rounds of the Delphi study. Thirty-five respondents were interviewed in the first round. During this interview the researcher obtained from the respondents the statements that they considered should be included in this role and philosophy description. During the second round the respondents rated the responses of the first round and in the third round those of the second round were revised after seeing the mean scores of the whole group and the three separate groups. The description of the role of a medical coordinator developed describes the role as it applies to: resident care; private physicians; planning, development and evalution of care; staffing of a facility; education; administration; and the training, experience, skills and attitude of a medical coordinator. When the description created was compared with that for the medical director in a long term care facility in the United States it was found that this study had described additional dimensions of the role, in particular the multi-disciplinary approach and the physician's knowledge, training, experience, skills and attitude. The results of the study show where there was agreement and where there were differences of opinion between the three professional groups. A long term care philosophy which was considered very important for a medical coordinator to promote, has been defined during the study. It focuses on the resident reaching his full potential, the creation of a special environment, as well as acceptance of disability, dying and death. Recommendations from the study are made for facilities which might be considering employing a medical coordinator, for planners deciding whether to provide funds for medical coordinators, for geriatric medical education and for the acceptance of a long term care philosophy in all parts of the health care system where there are long term care clients. / Medicine, Faculty of / Population and Public Health (SPPH), School of / Graduate

Magister Artium (Development Studies) - MA(DVS) / Brain drain has been labelled as one of the greatest development challenges facing African countries as it challenges capacity building, retention of skilled workers and sustained growth. Over the past two decades, a large number of Zimbabwean academics have left the country in search of economic opportunity and further academic training. This out-movement of academics has been exacerbated by political crisis and economic crisis in the country over the same period. Although some studies have sought to explain the causes, consequences and recommended policy responses to this human capital flight, they have not been able to critically assess, from the perspective of the emigrated academics, the conditions that would make them repatriate, their willingness to return to their home country and contribute to training, research and development; or their disposition towards engaging with Zimbabwean universities.

Canada has been active in attracting highly-skilled, foreign-trained workers to overcome its labour shortage, facilitate its economic growth, and enhance its global competency. While promoting gender equality in the workplace and advancing women’s labour market participation are ongoing focuses of Canada’s attention, the arrival of an increased number of skilled immigrant women and their marginalized experiences in the Canadian labour market reflects a critical problem that the underuse of highly skilled immigrant women’s professional skills might be a loss for both Canada and individual immigrants. This research reveals the lived experience of highly skilled Chinese immigrant women in the Canadian labour market, and analyzes how the barriers to their career restoration were constructed. It adopts Seyla Benhabib’s weak version of postmodern feminist theory and Dorothy Smith’s Institutional Ethnography methodology. Based on interview data with 46 highly skilled Chinese immigrant women, this research identifies these immigrant women’s standpoint within the institutional arrangements and understands the barriers to their career restoration as discursively constructed outcomes. This research contends that the settlement services for new immigrants funded by the federal government fall short of meeting the particular needs of highly skilled immigrants who intend to find highly skilled jobs that match their qualifications. This research also makes recommendations for improving existing language training and employment-related settlement services in order to better assist highly skilled immigrants in using their skills to a larger extent.

This thesis studies the role of the third sector organisation [TSO] in highly skilled refugees' employment integration in Sweden. It attempts to contribute to the migration studies literature and nonprofit sector studies by focusing on the underresearched highly skilled refugees and several TSOs in Sweden, one of the major receiving countries in Europe during the refugee crisis. It discovers the challenges faced by the highly skilled refugees and the TSOs' solution to help them overcome the obstacles using Bourdieusian capital theory. In doing so, the TSOs are also shaping the integration concept of the nation, which is proven to be ambiguous. On the one hand, they preserve the construction of refugees as needing care and their difference from Sweden as weakness. On the other hand, they challenge the idea that integration is primarily refugees' responsibility and attempt to change employers' unwillingness to hire with the concept of diversity as a strength. Despite that, the TSOs do not significantly challenge the dominant integration concept in Sweden and the state. This thesis argues that it may be explained by the strong trust between the government and civil society stemmed from the nation's historical development as an egalitarian welfare state.

Business leaders’ recognition of the increasing shortage of skilled workers to meet industry demand is a business problem. The purpose of this multiple case study was to explore strategies that business leaders used to recruit skilled workers at 3 manufacturing facilities in South Carolina. The human capital theory was the conceptual framework used for this study. Data were collected from face-to-face interviews with 3 business leaders who demonstrated successful recruitment strategies, a focus group of 4 skilled manufacturing employees hired during the time period of 2018-2019, and a review of company documents. Data were analyzed using Yin’s 5-step process. Six key themes emerged from data analysis: competitive wages and benefits; clean, safe, and stable work environment; employee investment and on-the-job training; use of recruiting agencies and skilled recruiters; strong community relations/image; and industry competition. The implications of this study for positive social change include the potential to provide significant knowledge and skills to manufacturing leaders conducive to the success of recruiting skilled workers to meet their needs. By meeting the demand for skilled manufacturing workers, organizations could boost their bottom line by increasing productivity and sales. Because of greater profits, business leaders could increase their contribution to the community with stable employment and the creation of additional jobs through supplier initiatives.

Over the past decades, Lesotho has been a source of, primarily, unskilled migrant labour entering South Africa, with Basotho men working on the South African mines and Basotho women restricted to domestic work. This dissertation examines the experiences of both ‘skilled’ and ‘unskilled’ Lesotho migrants currently living in South Africa. The study aims to establish those factors that are influential in prompting Lesotho citizens to leave Lesotho for South Africa. Moreover, it probes differences and similarities with regard to the work patterns encountered by skilled and unskilled workers as well as establishes the impact which migration has had on the lives of migrants. The literature tends to suggest that skilled workers face fewer restrictions and receive better treatment from management and colleagues in companies, while unskilled workers, on the other hand, may be exposed to considerable harassment, exploitation and poor treatment. This study concurs with the evidence in the literature in finding that unskilled workers are at a greater disadvantage when entering the South African labour market as compared to skilled workers. Moreover, it would appear that skilled workers are benefiting more in terms of their jobs, and in having their expectations met than unskilled workers. For the research participants in this study, xenophobia did not appear to be a serious factor, despite the fact that much public attention has been focused on the situation of foreign workers in South Africa. However, these workers from Lesotho highlighted racism as more of an obstacle than xenophobia. In addition, the study reiterates the popular findings that it is better job opportunities that remain the main motivation behind both skilled and unskilled workers migrating to South Africa with development, growth, training opportunities, mentoring, and interaction with more experienced colleagues also emerging as motivating factors. The discourse of the research participants also revealed social networks to be influential in the acquiring and maintaining of jobs. The study illustrates the relevance of ‘dependency’ theory for building understanding of the reasons why ‘skilled’ and ‘unskilled’ workers persist in migrating to South Africa. Finally, migration remains the ‘coming of age’ for Lesotho migrants, impacting positively on both their lives as well as the lives of their families. AFRIKAANS : Lesotho was tydens die afgelope paar dekades ʼn bron van ongeskoolde arbeid vir Suid-Afrika, waar manlike trekarbeiders gewoonlik in die mynwese werk en die vroulike trekarbeiders beperk is om betaalde huishoudsters te word. Hierdie dissertasie bestudeer die ervarings van ‘geskoolde’ en ‘ongeskoolde’ Lesotho trekarbeiders wat in Suid-Afrika woon. Die studie stel die faktore vas wat besluite rondom trekarbeid beïnvloed, veral díe wat die inwoners van Lesotho motiveer om hul land te verlaat om in Suid-Afrika te gaan werk. Die studie ondersoek boonop die verskille en ooreenkomste ten opsigte van werkspatrone wat geskoolde en ongeskoolde werkers teëkom. Dit stel ook vas wat die impak van trekarbeid op hierdie mense se lewens het. Die literatuur is geneig om voor te stel dat geskoolde arbeiders minder beperkinge ondervind en binne maatskappye beter behandel word deur bestuur en kollegas, terwyl ongeskoolde arbeiders aansienlike teistering en uitbuiting ervaar gepaard met swak behandeling. My studie stem ooreen met die literatuur – ek het gevind dat ongeskoolde arbeiders meer benadeel word as geskoolde arbeiders wat na Suid-Afrika migreer. Geskoolde arbeiders ervaar ook meer voordele ten opsigte van werk en hulle verwagtinge word verwesenlik. Deelnemers van hierdie navorsingsprojek het aangedui dat xenofobie nie ʼn ernstige faktoor was nie, al was daar baie publieke aandag gevestig op buitelandse arbeiders in Suid-Afrika. Vir die Lesotho arbeiders was rasisme ʼn groter struikelblok as xenofobie. Hierdie studie herhaal populêre bevindings dat daar beter werksmoontlikhede in Suid-Afrika is as in Lesotho, en dít is steeds die hoof motivering waarom geskoolde en ongeskoolde arbeiders daarheen migreer. Verdere motiverende redes was geïdentifiseer, naamlik: ontwikkeling, groei, opleidingsmoontlikhede, mentors, en interaksie met meer ervare kollegas. Die Lesotho arbeiders se besprekings het dit duidelik gemaak dat sosiale netwerke ‘n groot rol het in verband met werkwerwing en behouding daarvan. Hierdie studie illustreer die toepaslikheid van ‘afhanklikheidsteorie’ wat bydrae tot die begrip waarom geskoolde en ongeskoolde arbeiders na Suid-Afrika migreer. Laastens is migrasie steeds ʼn soort mylpaal vir Lesotho trekarbeiders en dit het ‘n positiewe impak op hul, en hul families se lewens.

There is a paucity of data on neurochemical abnormalities and associated effects on cognition and motor performance in rats ontogenetically treated with quinpirole, a rodent model of dopaminergic hyperfunction. The objective of the current study was to analyze the cognitive and motor effects produced by ontogenetic administration of quinpirole, a dopamine D2/D3 receptor agonist. Past research from this laboratory has shown that ontogenetic quinpirole treatment sensitizes D2 receptors and produces a variety of characteristic stereotypic behaviors in adult rats. In the current study, rats received quinpirole HCl (1 mg/kg/day) or saline from postnatal day (PD) 1 to PD 11 and went otherwise untreated until adulthood (PD 60). In Experiment 1, cognitive performance was assessed on the standard and matching-to-place versions of the Morris water task (MWT). In Experiment 2, skilled motor performance was assessed on the Whishaw reaching task and locomotor activity was also analyzed. We found that ontogenetically quinpirole-treated rats displayed a deficit on the probe trial given at the end of training of the standard version of the MWT but that there were no significant differences from control on the matching-to-place task. Additionally, rats treated in ontogeny with quinpirole showed significant enhancement in reaching accuracy on the Whishaw reaching task as well as increased locomotor activity relative to saline controls. These findings demonstrate that ontogenetic quinpirole treatments produce cognitive deficits, enhanced skilled reaching and hyperlocomotion. The behavioral changes produced by ontogenetic quinpirole treatment are consistent with dopaminergic hyperfunction, and possible mechanisms are discussed.

Neonatal quinpirole (dopamine D(2)/D(3) agonist) treatment to rats has been shown to increase dopamine D(2) receptor sensitivity throughout the animal's lifetime. Male and female Sprague-Dawley rats were neonatalally treated with quinpirole (1 mg/kg) from postnatal days (P) 1-21 and raised to adulthood. Beginning on P62, rats were administered the atypical antipsychotic olanzapine (2.5 mg/kg) twice daily for 28 days. Starting 1 day after the end of olanzapine treatment, animals were behaviorally tested on the place and match-to-place version of the Morris water maze (MWM) over seven consecutive days, and a yawning behavioral test was also performed to test for sensitivity of the D(2) receptor 1 day following MWM testing. Similar to results from a past study, olanzapine alleviated cognitive impairment on the MWM place version and increases in yawning produced by neonatal quinpirole treatment. Brain tissue analyses showed that neonatal quinpirole treatment resulted in a significant decrease of hipppocampal ChAT and BDNF RNA expression that were unaffected by adulthood olanzapine treatment, although adulthood olanzapine treatment produced a significant increase in cerebellar ChAT RNA expression. There were no significant effects of drug treatment on NGF RNA expression in any brain area. These results show that neonatal quinpirole treatment produced significant decreases of protein RNA expression that is specific to the hippocampus. Although olanzapine alleviated cognitive deficits produced by neonatal quinpirole treatment, it did not affect expression of proteins known to be important in cognitive performance.
