Academic literature on the topic 'Industrial attachment'

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and Economics<br>Recent surveys report an ever greater increase in the importance of internships for students and organizations. This thesis examines this importance of internship both for the students and organizations. Samples of 14 Esplanade Hotel employees were selected for the study. A major finding of this study reported four different benefits from all of the participants individually, as well as two major challenges affecting the importance. This thesis also argues some of the other benefits and challenges found in the prior literature by providing new findings and thus clearly stating how important internships really are for the students and the organizations.

Mestrado em Biotecnologia Industrial e Ambiental<br>A engenharia de tecidos tem estudado a combinação de vários materiais com células com o intuito de solucionar alguns problemas que as atuais terapias não conseguem dar resposta. Umas das respostas passa pelo desenvolvimento de pequenas estruturas, microgéis, que mimetizam a matriz extracelular e podem interagir de várias formas para criar uma estrutura tridimensional complexa. Este trabalho resume as principais técnicas de microfabricação que têm sido usadas no desenvolvimento de microgéis assim como as principais aplicações destas na engenharia de tecidos. Uma dessas técnicas, a microfluídica foi neste trabalho usada para produzir micropartículas de laminarina. Este polímero foi quimicamente modificado, adicionando grupos metacrilato que permitiram a reticulação das gotículas formadas pela microfluídica quando expostas a luz ultravioleta. Esta tecnologia permite encapsular lisados de plaquetas humanos durante a produção das micropartículas. As micropartículas apresentam elevado grau de monodispersão e uma forma esférica com diâmetro médio de 326.6 μm nas micropartículas com elevado grau de modificação e 303.3 μm nas micropartículas com baixo grau de modificação. Estudos de libertação demonstraram que diferentes graus de modificação da laminarina permite obter diferentes perfis de libertação das proteínas encapsuladas. Ao fim de 14 dias as micropartículas com alto grau de modificação tinham libertado 56.89 ± 1.03% da proteína encapsulada enquanto as micropartículas com baixo nível de modificação libertaram 35.31 ± 2.73%. As partículas funcionais foram então testadas como suporte para cultura de células. Os resultados mostraram que as partículas funcionalizadas com RGD e lisados encapsulados permitem uma eficiente adesão e expansão celular. As células cultivadas na superfície dos microgéis promovem ainda agregação dos mesmos em estruturas tridimensionais. Para aplicações clínicas, hidrogéis injetáveis/moldáveis são muitas vezes necessários para preencher defeitos de geometrias irregulares. Estes microgéis de elevada versatilidade podem vir a traduzir-se no desenvolvimento de sistemas de elevado desempenho para a produção de sistemas injetáveis para aplicações em engenharia de tecidos.<br>Tissue engineering has studied the combination of diverse biomaterials with cells in order to overcome some limitations of traditional therapies. One of solutions is related with the development of microstructures, microgels, that mimic the extracellular matrix and can assemble to create a complex three-dimensional structure. This work reviews the microfabrication techniques that been used to fabricate these microstructures as well as the main application of these in tissue engineering. One of this technique, microfluidic flow-focusing has been used to produce laminarin microparticles. This polymer was chemical modified, by adding methacrylated groups that allowed the photopolymerization of laminarin droplets when exposed to UV light. This technology allows to encapsulate human platelet lysates during fabrication of microgels by microfluidic. The microparticles shows high monodisperse and spherical shape with an average diameter around 326.6 μm in the microparticles with high degree of modification and 303.3 μm in the microparticles with low degree of modifications. The release studies demonstrate that different levels of modification of the laminarin microparticles allow to obtain different encapsulated proteins release profiles. At the end of 14 days the high methacrylated laminarin released 56.89 ± 1.03% of total amount of protein while low methacrylated laminarin released 35.31 ± 2.73%. The results showed that RGD functionalized particles with encapsulated platelet lysates allow an efficient cell adhesion and expansion. The cells cultured on the surface of microgels promote the assembly in three dimensional structures. For clinical applications, injectable/moldable hydrogels are several times necessaries to fill defects of irregular geometries. This highly versatility microgels can be translated in the development of the highperformance systems to production of injectable systems for applications in tissue engineering

Between 1997 and 2009, 47 major defense acquisition programs experienced cost overruns of at least 15% or 30% over their current or original baseline estimates, respectively (GAO, 2011, p. 1). Known formally as a Nunn-McCurdy breach (GAO, 2011, p. 1), the reasons for this excessive growth are myriad, although nearly 70% of the cases identified engineering and design issues as a contributing factor (GAO, 2011, p. 5). Accordingly, Congress legislatively acknowledged the need for change in 2009 with the passage of the Weapon Systems Acquisition Reform Act (WSARA, 2009), which mandated additional rigor and accountability in early life cycle (or Pre-Milestone A) cost estimation. Consistent with this effort, the Department of Defense has recently required more system specification earlier in the life cycle, notably the submission of detailed architectural models, and this has created opportunities for new approaches. In this dissertation, I describe my effort to transform one such model (or view), namely the SV-3, into computational knowledge that can be leveraged in Pre-Milestone A cost estimation and risk analysis. The principal contribution of my work is Algorithm 3-a novel, network science-based method for estimating the cost of unforeseen architectural growth in defense programs. Specifically, using number theory, network science, simulation, and statistical analysis, I simultaneously find the best fitting probability mass functions and strengths of preferential attachment for an incoming subsystem's interfaces, and I apply blockmodeling to find the SV-3's globally optimal macrostructure. Leveraging these inputs, I use Monte Carlo simulation and the Constructive Systems Engineering Cost Model to estimate the systems engineering effort required to connect a new subsystem to the existing architecture. This effort is chronicled by the five articles given in Appendices A through C, and it is summarized in Chapter 2.In addition to Algorithm 3, there are several important, tangential outcomes of this work, including: an explicit connection between Model Based System Engineering and parametric cost modeling, a general procedure for organizations to improve the measurement reliability of their early life cycle cost estimates, and several exact and heuristic methods for the blockmodeling of one-, two-, and mixed-mode networks. More generally, this research highlights the benefits of applying network science to systems engineering, and it reinforces the value of viewing architectural models as computational objects.

The purpose of this paper is to present a study that examines the underlying stucture of work/family conflict. Research has shown that reducing work/family conflict is beneficial to both employees and the organization by reducing turnover and increasing satisfction, production and commitment to the organization.

Universities in Zimbabwe have universally adopted a full-year integrated undergraduate student workplace-based learning pedagogy following the precedent set in 1991 by one pioneering university, the National University of Science and Technology. In this explorative study I analyse participants’ views, reflections and understanding of how the full-year model of workplace-based learning enhances quality academic practices and impacts on short, medium and long-term visions and opportunities for students and other stakeholders. I employed the embedded concurrent mixed methods research design (Creswell&Clark, 2007) using interviews with lecturers, university administrators and industry supervisors, as well as open-ended questions in three matched versions of a questionnaire to students, lecturers and industry supervisors respectively. The same questionnaire provided quantitative data that was statistically analysed. Interviews were conducted with 24 participants from the university under study, industry and other universities, while 363 university students, 40 NUST lecturers and 34 industry supervisors responded to the respective questionnaires. Students, lecturers and industry supervisors concurred on the coherence between industry experiences and university learning, the beneficial experiences at the workplace, and the relevance of those experiences to society, confirming the expressed view that industry-based learning promoted quality learning and teaching, and enabled students to become work-ready. However there were perceptions of inadequate student supervision and assessment, unsatisfactory student welfare safeguards, inadequate research enthusiasm among lecturers, and the lack of involvement of the whole spectrum of industry categories. There was an underlying regard for lifelong learning enabling societal transformation into the increasingly dominant industrialised culture. Lecturers indicated an appreciation for a holistic orientation to teaching and learning (Taylor, 2009), and were inclined towards adopting the hermeneutic approach to education (Danner, 2002). It is recommended, among other things, to revitalise effective practices through staff development efforts, increasing student knowledge and empowerment, and strengthening collaborative platforms between the university and its industry partners. Chief among the suggestions for future research is the understanding and promotion of student welfare during their placement in the workplaces.<br>Thesis (PhD)--University of Pretoria, 2012.<br>Science, Mathematics and Technology Education<br>unrestricted

The technology of Organic Light-Emitting Diodes has reached such a high level of reliability that it can be used in various applications. The required light emission efficiency can be achieved by transforming the triplet excitons into singlet states through Reverse InterSystem Crossing (RISC), which is the main process of a general mechanism called thermally activated delayed fluorescence (TADF). In this thesis, we theoretically analyzed two carbazole-benzonitrile (donor-acceptor) derivatives, 2,5-di(9H-carbazol-9-yl)benzonitrile (p-2CzBN) and 2,3,4,5,6-penta(9H-carbazol-9-yl)benzonitrile (5CzBN), and addressed the problem of how donor-acceptor (D-A) or donor-acceptor-donor (D-A-D) flexible molecular architectures influence the nature of the excited states and the emission intensity. Furthermore, we analyzed the RISC rates as a function of the conformation of the carbazole lateral groups, considering the first electronic states, S0, S1, T1 and T2, involved in TADF process. The two prototype molecules, p-2CzBN and 5CzBN, have a similar energy gap between the first singlet and triplet states (∆EST, a key parameter in the RISC rate), but different TADF performances. Therefore, other parameters must be considered to explain their different behavior. The oscillator strength of p-2CzBN, never tested as emitter in OLEDs, is similar to that of 5CzBN, which is an active TADF molecule. We also note that the presence of a second T2 triplet state, lower in energy than S1 only in 5CzBN, and the reorganization energies, associated with RISC processes involving T1 and T2, are important factors in differentiating the rates in p-2CzBN and 5CzBN. For p-2CzBN, the RISC rate from T2 to S1 is surprisingly higher than that from T1 to S1, in disagreement with El-Sayed rules, due to a large reorganization energy associated to the T1 to S1, process; while the contrary occurs for 5CzBN. These insights are important for designing new TADF emitters based on the benzo-carbazole architecture.

Ce travail de thèse concerne l'étude de l'écologie microbienne d'un atelier de découpe de viande bovine, dans le but de mieux comprendre la persistance bactérienne, c'est-à-dire, la présence répétée d'un même clone bactérien pendant une longue période malgré l'application bien conduite et régulière du nettoyage et de la désinfection (N-D). Des prélèvements par " chiffonnages " multiples de surfaces d'équipements ont été réalisés lors de trois campagnes de prélèvement espacées les unes des autres d'au moins six mois. Les prélèvements ont été réalisés sur un tapis convoyeur en polychlorure de vinyle (PVC) et sur des machines éplucheuses en acier inoxydable avant et après N-D. Nous avons quantifié les cellules totales (les cellules vivantes et les cellules mortes) par PCR quantitative en temps réel (qPCR), les cellules viables par EMA-qPCR, et les UFC (provenant de cellules cultivables) par dénombrement après incubation à 25°C sur gélose tryptone soja. Les résultats montrent qu'avant N-D, les cellules totales (en moyenne 5,6 - exprimé en log10 cellules/cm2 - sur PVC et 4,7 sur acier inoxydable) sont plus nombreuses que les cellules viables (4,5 sur PVC et 4,4 sur acier inoxydable) lesquelles sont plus nombreuses que les UFC (3,8 sur PVC et 2,9 sur acier inoxydable). Le N-D entraîne moins d'une réduction décimale (RD) des populations à l'exception des UFC sur acier inoxydable qui subissent 1,5 RD en moyenne. Ce dernier chiffre s'explique par des forces d'adhésion faibles. L'étude de la diversité des bactéries cultivables montre que sur un total de 51 genres identifiés, 13 seulement sont retrouvés lors des trois campagnes de prélèvements. Les isolats de ces 13 genres représentent 75, 72 et 62% des isolats des campagnes1, 2 et 3 respectivement. Parmi ces isolats, les plus fréquents sont (par ordre décroissant du nombre d'isolats) : Pseudomonas, Staphylococcus, Microbacterium, Acinetobacter, Chryseobacterium, Psychrobacter et Kocuria. Le génotypage d'isolats de 3 genres majoritaires (Staphylococcus, Pseudomonas et Acinetobacter) montre qu'une seule souche, Staphylococcus equorum, est sans aucun doute persistante. L'ensemble de ces observations montrent que l'écosystème varie d'une campagne à une autre. Ces modifications de la diversité bactérienne reflèteraient les modifications de flores des viandes traitées dans l'atelier, qui ont des origines multiples. En outre, il apparaît que, contrairement à ce qui est généralement admis, les bactéries à coloration de Gram négative cultivables sont plus facilement inactivées par le N-D que les bactéries à coloration de Gram positive. L'étude de l'écosystème par PCR-DGGE a permis d'identifier sept genres bactériens et montre que les espèces dominantes sont toutes sous forme vivante, autrement dit, aucune des espèces dominantes n'a été détectée uniquement sous forme de cellules mortes. Sur les sept genres identifiés six sont des Gram - dont majoritairement les genres Acinetobacter, Pseudomonas et Psychrobacter. Cette dominance montre que le N-D permet une forte perte de cultivabilité des bactéries Gram - mais qu'une grande partie n'est pas détachée. La dominance des bactéries Gram - observée par PCR-DGGE masque les staphylocoques qui ne sont pas détectés alors qu'ils sont majoritaires parmi la flore cultivable. Seul un genre bactérien, Propionibacterium, est identifié par PCR-DGGE uniquement mais il n'est trouvé qu'à une seule campagne et uniquement sur l'acier inoxydable avant N-D. En conclusion, l'avancée majeure de ce travail est la mise en évidence qu'une proportion importante de bactéries survit après les opérations très poussées de N-D mais pour une période transitoire.

碩士<br>國立臺灣海洋大學<br>航運管理學系<br>107<br>Peter Drucker once said: Innovation or Die. In the era of network technology innovation, the wave of financial technology is about to sweep across industries and every consumer’s life. The wide applications of FinTech will save consumers a lot of time on consumption and transactions with a more smooth and convenient financial service experience, by streamlining unnecessary processes and operations in the financial industry. While technology development has impacted the previous consumption pattern , the financial industry has to deal with the problem of human resources adjustment with the challenge brought by the FinTech. In a highly uncertain working environment, it will be a great challenge for today's financial practitioners to make self-adjustment and transformation. Therefore, the connection between environmental dynamics perception and industrial emotional attachment has led to the interest and motivation of this study. This research is based on the study of the relationship between the environmental dynamics perception, the industrial emotional attachment, and the interfering factors of the seniority and position, among the subjects of the Financial practitioners working in the Greater Taipei area. A total of 266 questionnaires were collected through questionnaire survey. The SPSS statistical software package is used as a tool for data analysis, and then tested by descriptive statistics, reliability analysis, hierarchical regression analysis, analysis of variance (ANOVA) , and Independent Sample t test. The main empirical results are as follows: 1. Environmental dynamics perception has a positive relationship with employees' industry emotional attachment. 2. Employee industry emotional attachment will have significantly differences due to different seniority. 3. Employee industry emotional attachment will be significantly different due to the position of the position. 4. The seniority will interfere with the relationship between environmental dynamics perception and industrial emotional attachment. The finding of this study can make recommendations to the financial industry as a reference for human resources management, and provides relevant recommendations for follow-up researchers.
