My thesis The Benefits of Loss: Life Strategies and Negotiations of Identity amongst Indian Transmigrants in Melbourne, Australia is a study of a community of transmigrants of prevailingly Indian origin who immigrated to Melbourne Australia. The majority of these persons came to Australia on overseas student visas in order to pursue a university education; this later created an opportunity for them to obtain permanent residency in Australia through The General Skilled Migration program. This specific migration flow of persons with high skill and education has been supported by the Australian government in the last decade as a reaction to the increased mobility of population in the globalized world. The study focuses on the life strategies and negotiations of particular individuals attempting to show how these global trends are mediated in specific stages of their lives. At the centre of my interest lies a social network of 14 friends who constitute a transnational community in Melbourne, their motivations of migration, the stories capturing their experiences of the migration process, life strategies in the territory of a foreign nation-state and everyday negotiations of both individual and collective identity.

The thesis aims to estimate the future migration flows from Ukraine, Belarus, and Moldova to the EU. Based on the experience of previous EU enlargements and econometric modelling using the method of Ordinary Least Squares with Fixed Effects, multiple forecasts are created. The forecasts capture the likely development of migration flows in the event of collapse of labour market restrictions as well as the case of no labour market liberalization. The results show that migration flows are expected to be moderate, posing no threats to the stability of the labour markets of EU member states. The increase of migration due to the accession to the EU is likely to be short-term, without substantial impacts in the long-run. Ukraine has the biggest migration potential and is likely to supply the highest amount of labour migration.

In this context, the Intensive Care Units (ICU) has been high-risk areas for the selection of multiresistant strains. The environment (objects, equipment and surfaces) of an ICU can also get contaminated, and microorganisms may remain viable for a long period of time, and can colonize patients, employees, visitors and other environments. The objectives of the study were to determine the prevalence of S. aureus contamination in patients and ICU environment of a university hospital in the city of Goiânia-GO, as well as to determine the antimicrobial susceptibility and virulence profile of the isolates and perform molecular typing of methicillin-resistant S. aureus (MRSA) isolates. The isolation and presumptive identification of S. aureus by phenotypic techniques and the confirmation of the species by detection of femA gene by PCR were performed. The isolates were subjected to diskdiffusion test for determining antimicrobial susceptibility profile, and those showing resistance to cefoxitin were subjected to E-Test® to determine the minimum inhibitory concentration (MIC) to oxacillin and vancomycin, as well as the mecA gene detection for identification of MRSA strains. In these isolates the SCCmec typing was performed. In all S. aureus isolates were detected virulence factors-coding genes and held the genetic comparison for determining the similarity profile by pulsed field gel electrophoresis. Fifty hundred and thirty six swabs were collected being 134 of patients and 402 of ICU environment. The prevalence of colonization by S. aureus was 12.7% (68/536), being 13.4% (18/134) for patients and 12.4% (50/402) for the environment. The highest resistance rate presented was to penicillin (85.3%) followed by erythromycin (69.1%) clindamycin (66.2%) and sulfamethoxazole-trimethoprim (54.4%). Fifty-six isolates (82.4%) were classified as multiresistant. The prevalence of MRSA was 20.6% (14/68), and seven isolates (10.3%) presented intermediate susceptibility to vancomycin (VISA). The inducible resistance phenotype (iMLSb) was found in 11 strains (16.2%) and the constitutive resistance (cMLSb) in 25 (36.8%). Eleven isolates showed genes encoding for at least one virulence factor and were detected six virulence profiles. Of the 14 MRSA strains, six (42.9%) were SCCmec type IV, five (35.7%) SCCmec type I, two (14.3%) SCCmec type II and one (7.1%) SCCmec type III. PFGE analysis showed genetic diversity among the isolates, although a cluster grouped 16 isolates showing the spread of the bacteria among patients and environment. One MRSA isolate showed genetic relationship to the USA300 strain and two isolates MRSA/VISA were similar and another identical to the clone USA400. The results suggest that the prevalence of S. aureus and MRSA remains high in health institutions, especially in the ICU, with high rates of antimicrobial resistance and pathogenic potential. The detection of these microorganisms in the environment shows risk of cross-transmission primarily via health professionals. Identification of isolates with genetic background of strains acquired in the community alert to a flow of intra and inter- hospital and community environment. In addition, it is believed that environmental surfaces can be acting as reservoirs of genes of resistance and virulence as well as potential sources of contamination to patients, professionals and environments. / Staphylococcus aureus é um importante patógeno relacionado a infecções nosocomiais, com elevadas taxas de prevalência, morbidade e mortalidade. Nesse contexto, as Unidades de Terapia Intensiva (UTI) tem sido áreas de alto risco para a seleção de cepas multirresistentes. O ambiente (objetos, equipamentos e superfícies) de uma UTI também pode se contaminar, e os microrganismos podem permanecer viáveis por um longo período de tempo, podendo colonizar pacientes, trabalhadores, visitantes e contaminar ainda outros ambientes. Os objetivos do estudo foram determinar a prevalência de colonização por S. aureus em pacientes e ambiente da UTI de um hospital universitário na cidade de Goiânia-GO, bem como o perfil de susceptibilidade antimicrobiana e perfil de virulência dos isolados e realizar a tipagem molecular dos S. aureus resistentes à meticilina (MRSA). Foi realizado o isolamento e identificação presuntiva de S. aureus por técnicas fenotípicas e a confirmação da espécie pela detecção do gene femA por PCR. Os isolados foram submetidos ao teste de disco-difusão para determinação do perfil de suscetibilidade antimicrobiana e aqueles que apresentaram resistência à cefoxitina foram submetidos ao E-test® para determinação da concentração inibitória mínima à oxacilina e vancomicina, assim como, à detecção do gene mecA para identificação das cepas MRSA. Nestes isolados foi realizada a tipagem do SCCmec. Em todos os S. aureus isolados foi realizada a detecção dos genes codificadores de fatores de virulência e a comparação genética para determinação do perfil de similaridade por eletroforese em gel em campo pulsado. Foram coletados 536 swabs sendo 134 de pacientes e 402 de ambiente de UTI. A prevalência de colonização por S. aureus foi de 12,7% (68/536), sendo 13,4% (18/134) para pacientes e 12,4% (50/402) para o ambiente. A maior taxa de resistência apresentada foi à penicilina (85,3%) seguida da eritromicina (69,1%), clindamicina (66,2%) e sulfametoxazol-trimetoprim (54,4%). Cinquenta e seis isolados (82,4%) foram considerados multirresistentes. A prevalência de MRSA foi de 20,6% (14/68), houve ainda a existência de sete (10,3%) isolados com suscetibilidade intermediária à vancomicina (VISA). O fenótipo de resistência induzível (iMLSb) foi encontrado em 11 isolados (16,2%) e o de resistência constitutiva (cMLSb) em 25 (36,8%). Onze isolados apresentaram genes codificadores para pelo menos um fator de virulência pesquisado, sendo detectados seis perfis de virulência. Das 14 cepas MRSA, seis (42,9%) foram SCCmec tipo IV, cinco (35,7%) SCCmec tipo I, duas (14,3%) SCCmec tipo II e uma (7,1%) SCCmec tipo III.A análise de PFGE revelou diversidade genética entre os isolados, apesar de que um cluster agrupou 16 isolados mostrando a disseminação da bactéria entre pacientes e fômites. Um isolado MRSA mostrou relacionamento genético à cepa USA300 e dois isolados MRSA/VISA foram semelhantes e outro idêntico ao clone USA400. Os resultados sugerem que a prevalência de S. aureus e MRSA permanece elevada em instituições de saúde, especialmente em UTI, com elevadas taxas de resistência antimicrobiana e potencial patogênico. A detecção desses microrganismos no ambiente evidencia risco de transmissão cruzada desses patógenos, principalmente via profissionais da saúde. A identificação de isolados com background genético de cepas adquiridas na comunidade alerta para um fluxo de disseminação intra e inter-ambiente hospitalar e comunitário. Além disso, acredita-se que as superfícies ambientais podem estar atuando como reservatórios de genes de resistência e virulência, bem como fontes potenciais de contaminação de pacientes, profissionais e ambientes.

Visa是全球第一大的國際支付卡組織，然其自1970年成立至今，不過短短30年，這之間組織成長的速度令人驚嘆，但由從前組織成長理論似乎無法解釋其中所隱含的經濟意義，因此本研究嘗試以新經濟現象中的網路外部性理論來觀察解釋Visa組織成長的過程-隨著使用者的增加，整個系統的價值也隨之增加，且在不斷的循環自我增強下，整個系統呈現非線性的快速成長。 此外，Visa組織的創辦者Dee Hock(1998)在「亂序」一書中提及Visa是個亂序（處於混亂和秩序之間）的組織，因此本研究亦由混沌理論的觀點觀察Visa組織的運作方式，瞭解其是如何進行自我組織、自我成長、自我演化，又這樣一個龐大的價值交換體系，在快速成長擴充的過程中又是如何管理運作的。 最後，本研究就網路外部性和混沌理論觀點下所觀察到的現象進行進一步之比較探討，找出其中相關之處，觀察兩者間是否有互相強化之關連，發覺Visa此一混沌邊緣組織的運作方式強化了其網路外部性的效果，也更加造就了Visa的成功。

The main purpose of the thesis is to evaluate the impacts of EU visa policy on incoming of Czech republic. For achieving this main purpose there were also defined sub-goals, which include comparison of the indicators of inbound tourism in Czech republic before and after joining Schengen Area and assessment of economic impact of applied EU visa policy on Czech republic. The diploma thesis is divided into seven chapters. The first three chapters introduce the theoretical overview of basic terms in the international tourism, statistical monitoring of tourism and visa policy. The next part of the thesis is devoted to analyzing the influence of EU visa policy on selected countries whose nationals require visas to EU. The final chapter appraises the results and brings the forecast of the situation without existence of common visa policy.

Thesis (Ed.D.)--Boston University / The influx of international graduate students in science and engineering to the U.S. has changed since the terrorist attacks of September 11, 2001. The implementation of the Student and Exchange Visitor Information System (SEVIS) and related F-1 visa policies have required a higher level of scrutiny of the student visa procedures, and introduced strict student monitoring policies and measures. In addition, the SEVIS monitoring and compliance system has altered the operation of international student service offices, affected the students they serve, and the operation of the universities enrolling international students. This study investigated the effects of SEVIS on graduate programs in science and engineering and their students. Information was gathered from respondents from the 60 universities having the highest population of intemational students in these fields, according to NSF. Respondents included department administrators, admissions officials, and SEVIS professionals. Data V111 were collected from 75 on-line survey respondents and in 21 semi-structured interviews. The results of this study suggest that many international students are negatively affected by SEVIS, impacting their ability to remain in-status and to understand how the system works. To counter this, department administrators, SEVIS professionals, and student advisors have increased their level of support for these students, providing them guidance on how to remain in-status and how to improve their social and academic experience in the United States. As a result, relatively few international students are deported for falling out-of-status in SEVIS. The data also made clear that program administrators and admissions officials have little knowledge about SEVIS, F -1 visa policies, and their influence on international enrollments. Finally, this study provided evidence of an increased workload for international student advisors and SEVIS professionals. Universities have had to hire additional staff, increase their information technology investment in linking home-grown student service systems with SEVIS, and proactively anticipate any hurdles that international students may have and resolve them as expeditiously as possible. / 2031-01-01

The Internet has grown from its modest academic beginnings into an important, global communication medium. It has become a significant, intrinsic part of our lives, how we distribute information and how we transact. It is used for a variety of purposes, including: banking; home shopping; commercial trade - using EDI (Electronic Data Interchange); and to gather information for market research and other activities. Owing to its academic origins, the early developers of the Internet did not focus on security. However, now that it has rapidly evolved into an extensively used, global commercial transaction and distribution channel, security has become a big concern. Fortunately, the field of information security has started to evolve in response and is fast becoming an important discipline with a sound theoretical basis. The discipline views the twin processes of identification and authentication as crucial aspects of information security. An individual access attempt must be identifiable prior to access being authorised otherwise system confidentiality cannot be enforced nor integrity safeguarded. Similarly, non-denial becomes impossible to instigate since the system is unable to log an identity against specific transactions. Consequently, identification and authentication should always be viewed as the first step to successfully enforcing information security. The process of identification and authorisation is, in essence, the ability to prove or verify an identity. This is usually accomplished using either one or a combination of the following three traditional identification techniques: something you possess; something you know; or something you are. A critical consideration when designing an application is which identification method, or combination of methods, from the three described above to use. Each method offers its own pros and cons and there are many ways to compare and contrast them. The comparison made in this study identifies biometrics as the best solution in a distributed application environment. There are, however, two over-arching hindrances to its widespread adoption. The first is the environment’s complexity - with multiple applications being accessed by both the public and the private sectors - and the second is that not all biometrics are popular and no single method has universe appeal. The more significant hindrance of the two is the latter, that of acceptance and trust, because it matters little how good or efficient a system is if nobody is willing to use it. This observation suggests that the identification system needs to be made as flexible as possible. In a democratic society, it could be argued that the best way of ensuring the successful adoption of a biometric system would be to allow maximum freedom of choice and let users decide which biometric method they would like to use. Although this approach is likely to go a long way towards solving the acceptance issue, it increases the complexity of the environment significantly. This study attempts to solve this problem by reducing the environment’s complexity while simultaneously ensuring the user retains maximum biometric freedom of choice. This can be achieved by creating a number of central biometric repositories. Each repository would be responsible for maintaining a biometric template data store for a type of biometric. These repositories or “Biometric Authorities” would act as authentication facilitators for a wide variety of applications and free them from that responsibility. / Dissertation (MSc (Computer Engineering))--University of Pretoria, 2005. / Electrical, Electronic and Computer Engineering / MSc / unrestricted

Uppsatsen visar hur prästen och tonsättaren Lars Åke Lundberg har medverkat till den andliga visans teologiska bestämning i en banbrytande och samhällsomvälvande tid 1965-1973. Studien omfattar det urval av andliga visor Lundberg själv valt att tonsätta/översätta under tidsperioden. I uppsatsen görs en analys av vistexterna utifrån några valda samhällsteologiska motiv. Resultatet av textanalysen sammankopplas med den tidsanda, som då rådde. Uppsatsen bidrar också till en samhällsteologisk förståelse av vad som hände inom Svenska kyrkan under perioden. Förståelsen av den politiska förändringen kom inifrån Svenska Kyrkan i första hand och inte genom yttre påverkan. / The essay shows how the priest and composer Lars Ake Lundberg has contributed to the theological determination of the spiritual song in the pioneering and revolutionary period of the society in 1965-1973. The study includes the selection of spiritual songs that Lundberg himself chose to compose/translate during the time period. In the essay, analaysis of the lyrics is made based on some selected theological motives belonging to the society. The result of the analysis of the texts is connected with the spirit of the time, which then prevailed. The essay also contributes to a theological understanding of what happened whithin the Church of Sweden during the period. The understanding of the politcial change came from the Church of Sweden itself and not primarly through external influences.

Performing measurements of samples that contain chemical substances is a time consuming task if the measurement instruments are small and require high precision. A single measurement session can often contain a large amount of samples, which is why it is crucial to automate this process. The solution, which is discussed in this report, is a Graphical User Interface that allows a user to control three linear motors that can move in the X-, Y-, and Z-axis. Movement of the motors results in the movement of the sampling platform, which allows a measurement instrument to be inserted and ejected from each sample with a much higher precision than a human is capable of. Automating the process does not only result in a more accurate and precise measurement process, but also a more efficient process, since the sample size can be decreased. By decreasing the sample size, it is also possible to increase the number of samples to perform measurements on. The results shows an increase in accuracy and a reduction of the required supervision over the sampling process. Moreover, our solution also reduces power consumption since the equipment used in the analyses requires less uptime. / Att utföra mätningar av prover som innehåller kemiska ämnen är en tidskrävande uppgift om mätinstrumenten är små och kräver hög precision. En enda mätsession kan ofta innehålla en stor mängd prover, därför är det väsentligt att automatisera denna process. Lösningen, som diskuteras i denna rapport, är ett grafiskt användargränssnitt som låter en användare styra tre linjära motorer som kan röra sig i X-, Y- och Z-led. Rörelse av motorerna resulterar i att provtagningsplattformen rör sig, vilket gör att ett mätinstrument kan matas in och ut från varje prov med en mycket högre precision än vad en människa är kapabel till. Att automatisera processen resulterar inte bara i en mer exakt mätprocess, utan också i en mer effektiv process, eftersom provers storlek kan minskas. Genom att minska provstorleken är det också möjligt att öka antalet prover att utföra mätningar på. Resultaten visade en betydelsefull ökning av noggrannhet och en minskning av nödvändig övervakning av systemet. Vår lösning innebär också en minskning av strömförbrukningen eftersom den utrustning som används i analyserna kräver kortare drifttid.

The fact that many OECD countries are reliant on international medical graduates (IMGs) to serve their most vulnerable has become even more apparent in the wake of Covid-19. This dissertation examines the role that nation brands play on the international physician labor market and how visa regimes and migration industries shape IMG pathways to Sweden versus US; two widely different societies where around a third of all doctors are IMGs. The US and Sweden represent two different approaches to addressing the same problem — solving a shortfall of healthcare providers, especially in rural areas populated by ethnic minorities and low-income families. While many Swedish regions actively attempts to facilitate the incorporation of IMGs through an intra-European physician recruitment industry, the US seem to rely on the attraction of its political economy and has done little to modify the substantial financial and visa-related obstacles that IMGs face. As a high-skilled immigrant group, immigrant physicians occupy a complex position of advantage and disadvantage; they are privileged in comparison to low-income migrant workers and unauthorized immigrants, yet face more barriers in comparison to domestic physicians, and are often informally sorted into less prestigious positions. This study centers the two largest immigrant physician groups in each country: Indians in the US and Poles in Sweden. The experiences of these labor migrants are triangulated against a third IMG group that have undergone the asylum process in order to reach their host societies — Iraqis. / 2025-05-11T00:00:00Z
