Chen, Qiongqiong. "Globalization and transnational academic mobility| The experiences of Chinese academic returnees". Thesis, State University of New York at Buffalo, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3683013.
Texto completo da fonteResumo:
The purpose of this study was to examine the way US returned academics negotiate their academic identities and professional practices at China's research universities in the context of higher education internationalization. To be specific, it explored how western doctoral education and work experiences affect returnees, and how these returnees reconstruct what it means to be and become a Chinese professor as they renegotiate the existing university rules, cultures, and practices. Second, it examined the complexity of the internationalization of Chinese universities and the role that returnees play in the process. This study went beyond economic accounts of academic mobility and placed the investigation in a broader frame of social and cultural analysis in order to go deep into the everyday experiences of the returning scholars around issues of their sense of identity, as well as their ways of connecting and bringing about changes in their work communities. It shed light on scholarly debates on transnational academic mobility and higher education internationalization in China.
This study utilized qualitative methodology to explore the everyday experiences of the returned Chinese scholars. The sample was comprised of 52 US doctoral recipients from different disciplines at five research universities in both east and west China. In-depth interviews were used as the primary method of data collection. Other methods, such as non-participatory observation, informal conversations, and documentary analysis, were also used to complement the interview data. An inductive analysis approach was employed to generate codes, categories, and themes from the raw data. Data interpretation and reporting followed the Standards for Reporting on Empirical Social Science Research in AERA Publications.
This study finds that 1) the returnees were motivated to return by China's rapid economic and social development, policy initiatives on mobilizing return moves, and better career opportunities that the improved academic system provided. They also returned for cultural and personal reasons, including social attachment, cultural belonging, self-realization, and family considerations. It suggests that the act of returning is a complex process that involves both personal choices and negotiations of various conditions and regions. 2) The integration of returnees into Chinese universities was not always a linear process, but constrained by the existing university structures and power relations. These include the bureaucracies of university administration, local politics and complicated interpersonal relationships, the problematic evaluation and funding system, and a lack of an efficient administrative system that supports high quality of teaching and research. 3) The returnees were not passively adapting to the structure. Instead, they were strategically drawing upon and using part of their transnational gains and advantages to create a new space for their professional careers and China's higher education innovation. They can be regarded as a driving force for change, either by introducing new teaching and research practices at the operational level, or calling for organizational changes by taking up leadership positions at the institutional level.

Hu, Yijun. "Being and Becoming Academics: A Case Study of Chinese Returned Academics Working on Knowledge Recontextualisation". Thesis, Griffith University, 2020. http://hdl.handle.net/10072/397594.
Texto completo da fonteResumo:
This study investigated the teaching and research work of early career Chinese academics in an elite Chinese university after they completed their doctoral studies in English-speaking countries. In particular, the study focused on how this group of academics brought back discipline-specific knowledge and research methods which they acquired during their overseas research studies. Secondly, the study examined how they translated and appropriated such knowledge and methods throughout their everyday work in the Chinese context. Thirdly, this study explored how the academics exercise their agency and construct professional identities while positioning themselves in the international research community and contributing to the Chinese higher education sector via knowledge recontextualising work.
The research problem was contextualised in the policy literature documenting the rapid rise of China in the global higher education arena. This literature noted policies which encouraged Chinese students to complete their research qualifications in the West before returning to work in China. While a number of empirical studies have investigated the experiences of Chinese students who have completed research degrees in the West, these studies have mainly focused on summarising the reasons for their return, the working situations upon their return, the benefits of studying abroad, work challenges encountered, and how they lived up to university expectations. By contrast, this thesis focuses on the specifics of knowledge translation or recontextualisation undertaken by this cohort based on their transnational education experiences.
This thesis draws on concepts from the sociology of education, mainly the work of Basil Bernstein (1971, 1990, 1996, 2000) to analyse the empirical data. In addition, it extended Bernstein’s concept of the pedagogic device by incorporating ideas from theories of educational globalisation (Appadurai, 1996, 2000) to understand the increasing flows of knowledge and knowledge exchanges at an international level. The study adopted a case study approach to explore the research questions. The empirical data was collected through in-depth semi-structured interviews with nineteen early career returned academics working in humanities and social sciences (HASS) faculties of an elite research-intensive Chinese university. The academics provided accounts of their teaching, research and service work, and specifically talked about how their overseas research study had informed their current work. As the beneficiaries of national policies around internationalisation, the academics, upon return to China with their Western qualifications, brought to life such policy discourse through their everyday pedagogic work.
The rich accounts provided by the early career returned academics are analysed and presented in three ways. Firstly, the returned academics’ professional life and the intensification of academic work are portrayed in the format of composite biographies. The analysis draws attention to the conflicts between the academics who returned with Western qualifications and their locally trained colleagues, as well as between the academic work captured in the early career academics’ imaginations and that in reality. The analysis explores the ways in which the early career academics managed the pressures of work and forged their professional identities and trajectories. Secondly, this thesis documents the returned academics’ comments on the formation of disciplinary knowledge discourses in HASS areas and power structures embedded in the knowledge production and reproduction. Additionally, their attempts of referencing and presenting diverse knowledge discourses through teaching and research and empowering themselves and Chinese university students as knowers, as termed by Maton (2014; 2013), formed further topics of discussion. Lastly, the pedagogic practices of the academics as they produced and reproduced knowledge in the Chinese university are detailed. Through introducing the course curricula, pedagogic models and assessment approaches that were widely implemented in elite Western universities, they aimed at preparing their Chinese students for future studies in the West and fuller participation in the global research community. However, they also commented on the resistance to such pedagogic changes from students, their other colleagues, and entrenched institutional practices.
The research makes three major contributions to theory and practice. Firstly, this study extended Bernstein’s theoretical corpus to capture the movement of knowledge/ideas across national borders in the increasingly globalised arena of higher education. In doing so, it allowed an exploration of educational governance beyond the national level as academics recontextualised knowledge from one nation to another, and within the official policy parameters of their employing institution in China. In addition, this study reported the Chinese early career returned academics’ conduct of their teaching, research and
service work, and the resulting powerplays as they were positioned in and by the local and international research communities. This research is instructive for the returned academics in navigating their professional development during their early career stage. Lastly, this study presented the ways in which the internationalisation policies of the Chinese government had been translated and recontextualised within a specific university context. To build upon the positive consequences of these policies in recruiting the returned academics, this study suggested further development of the policies to better support this group of academics in relocating back to the academy of their home country and translating and implementing their overseas-attained knowledge, skills and modes of pedagogies in their daily work.Thesis (PhD Doctorate)

Kline, James Jeffrey. "Star Academics: Do They Garner Increasing Returns?" PDXScholar, 2016. https://pdxscholar.library.pdx.edu/open_access_etds/2713.
Texto completo da fonteResumo:
This study examines the criteria which help academics receive National Institute of Health funds (NIH). The study covers 3,092 NIH recipients and non-recipients in the same department or institute at twenty-four universities. The universities are drawn from those below the top twenty in terms of receipt of NIH funds. With regards to performance, non- recipients have lower performance than recipients. A key determinant of the receipt of NIH funds is individual performance, as measured by the number of articles published and average citations per article in the two years immediately prior to the grant application. Professors receive more NIH money than do associates and assistant professors. Other positive contributors are the field of study, whether the academic has both a PhD. and Medical degree, and has licensed an innovation, been involved in the start of a new business and patented an invention through the university. To the extent that individual performance criteria represent the quality of the research proposal, allocation of NIH funds is based on merit.
A Tobit model indicates that being highly cited does not guarantee increasing returns. Likewise, career citations have only a small statistically significant impact. In addition, a negative coefficient associated with the second derivatives of both articles published in 2006-07 and their associated citations indicate diminishing marginal returns.

White, Mark Voss. "Abnormal returns on asset exchanges". Diss., The University of Arizona, 1992. http://hdl.handle.net/10150/186098.
Texto completo da fonteResumo:
Asset exchanges, such as mergers and acquisitions, typically give rise to abnormal returns. This dissertation tests a fads hypothesis for abnormal returns on initial public offerings, an asset exchange in which traders exchange cash for issuers' new shares. Initial public offerings, or IPOs, exhibit positive abnormal returns on the date of the exchange when trading prices, on average, rise above offering prices. IPOs also exhibit negative abnormal returns after the exchange as trading prices, on average, fall relative to those on comparable-risk assets. In the fads hypothesis, IPOs occur when a fad, or mass psychogical movement, induces traders to bid the trading prices of certain types of assets up over their intrinsic prices. These high trading prices offer a quasi-arbitrage opportunity that motivates unaffected traders to short-sell seasoned shares affected by the fad or issue new shares based on like assets. For the fads hypothesis to explain abnormal returns on IPOs, fads among traders must allow price bubbles to persist long enough for rational traders to issue IPOs, and rational traders must actually do so. This dissertation's experimental spot asset double auction markets show that the duration of price booms, or rising differences between trading prices and intrinsic prices, significantly increases with an increase in asset life, suggesting that differences between trading prices and intrinsic prices can persist. This laboratory finding parallels field findings that closed-end fund trading prices only converge to net asset values (an intrinsic price proxy) when secondary trading ceases due to merger, liquidation or open-ending. This finding is consistent with bubbles persisting long enough for quasi-arbitrage responses. This dissertation also shows that an apparent fad in closed-end country funds led issuers and underwriters to organize an extraordinary number of IPOs in late 1989 and early 1990. These issuers profited by promising to purchase assets at net asset values and selling shares based on that promise at a premium. The shares issued during this apparent fad had positive abnormal returns in their initial rise from offering prices to trading prices, and subsequently had negative abnormal returns as their premium trading prices fell to discounts. This closed-end country fund findings are consistent with the fads hypothesis of abnormal returns on IPO asset exchanges.

This study examines the affect of winning an Academy Award on the stock price of parent companies. On average, receiving an Oscar has no significant impact on the stock of parent companies during the few days surrounding the broadcast of the Academy Awards. The findings of this study introduce questions of external interference and possible limitations on this type of research. However, my study sheds light on future topics of investigation for analyzing the effects of televised award shows on the stock market.

Weigand, Robert Alan. "The cointegrating relationship between stock prices and trading volume: Evidence regarding the predictability of security returns". Diss., The University of Arizona, 1993. http://hdl.handle.net/10150/186294.
Texto completo da fonteResumo:
This study develops and tests the hypothesis that stock prices and trading volume are influenced by the same set of fundamental forces. The implications of this hypothesis for modeling and forecasting stock returns are also explored. Part 1 identifies several effects likely to contribute to the observed positive correlation between stock prices and trading volume. Among these are the various constraints that prohibit certain classes of investors from short selling; the disposition effect, which is the tendency for investors to hold losing investments too long and sell winners too early; and the prevalence of positive feedback trading strategies in financial markets. Part 1 also presents a simple supply and demand example which demonstrates that both asset prices and trading volume are influenced by the information signals received by traders in efficient markets. Part 2 presents empirical tests of the hypothesis that stock prices and trading volume are determined by a set of common factors. The presence of a common stochastic trend (cointegration) is shown to be consistent with the above hypothesis. Stock prices and trading volume are found to be cointegrated, which is interpreted as evidence in support of the common factor hypothesis. The theoretically correct method for modeling cointegrated variables, known as an error-correction model (ECM), explains over 4% of the variability in monthly stock returns from 1962-1991. An index of the total dividends paid to the Standard and Poor's 500 is included as an instrument for the information set hypothesized to be a common factor in stock prices and trading volume. After demonstrating that stock prices, trading volume and the dividend index are part of a trivariate cointegrated system, the dividend index is included into the ECM of stock prices. The explanatory power of the ECM rises to 6.5% due to the inclusion of the dividend index. Part 3 develops a forecasting model of monthly stock returns based on the ECM presented in Part 2. Out-of-sample forecasts of monthly stock returns are generated from this model, as well as other forecasting models chosen from the literature on the predictability of security returns. Under a variety of conditions, both with and without transactions costs, trading rules generated by the forecasting model of Conrad and Kaul (1989) consistently outperform a buy and hold strategy. The ECM forecasting model performs no better than a macroeconomic or random walk model, and underperforms a buy and hold strategy in the presence of transactions costs. The overall finding from Part 3 is that the simple time series model of Conrad and Kaul generates forecasts which beat the market conclusively for the thirteen year period spanning January, 1978 to December, 1990.

Yao, Juan. "A dynamic investigation into the predictability of Australian industry stock returns". Curtin University of Technology, School of Economics and Finance, 2004. http://espace.library.curtin.edu.au:80/R/?func=dbin-jump-full&object_id=15148.
Texto completo da fonteResumo:
This thesis involved an empirical investigation of the predictability of Australian industrial stock returns using a dynamic state-space framework. The systematic risks of industrial portfolios were examined in a stochastic market- model. The systematic risks of industry portfolios are found to be stochastic processes. Most of the industry groups have time-varying systematic risks that are mean-reverting to their stable or moving long-term mean. However, the investment and financial services, alcohol and tobacco, gold, insurance and media industry groups have rather random systematic risks. The time-varying market model provides a better explanation of the portfolio returns than the single-index model since it captures the stochastic properties of market risk. Further, a Bayesian dynamic-forecasting model was employed to examine the explanatory power of a set of economic and financial variables. The unanticipated components of the term-structure variable, the interest-rate variable and the aggregate-dividend-yield variable were shown to be significant in explaining the industry portfolio excess returns. The comparison between multivariate analysis and univariate analysis strongly indicates that the correlations within industries are critical in the investigation of the predictability of returns. In the out-of-sample analysis, a maximally predicted portfolio (MPP) was constructed based on the updated economic and financial information; however, the predictability of the MPP did not exceed that of a naive forecast.Furthermore, the market timing ability associated with the predictability of the MPP was insignificant. The industry-group-rotation strategy is able to enhance the industry portfolio performance, but the predictability only contributes a small proportion of the profits. The results indicate that the industry returns contain predictive components; however, investors are less likely to exploit the existing predictability to gain excess profit. The level of predictability discovered here does not contradict market-efficiency theory.

Paris, Tex. "Perceived Attitudes of the Self-Concept of Dropouts Who Returned to an Alternative Education School and Coordinated Vocational Academic Education Students". Thesis, University of North Texas, 1988. https://digital.library.unt.edu/ark:/67531/metadc332445/.
Texto completo da fonteResumo:
The problem of this study was to determine if there were differences in perceived attitudes of self-concept between young people who returned to alternative education after dropping out of public education and educationally disadvantaged at-risk youth in Coordinated Vocational Academic Education (CVAE) classes as measured by the Piers-Harris Children's Self-Concept Scale. The hypotheses formulated for the study predicted no significant difference in mean attitude self-concept scores of returned dropouts to alternative schools and CVAE students enrolled in junior high school preemployment laboratories and high school students enrolled in Cooperative Education classes as measured by the Piers-Harris scale; and no significant change in mean attitude self-concept scores of former dropouts enrolled in alternative education centers and CVAE students as measured by the Piers-Harris scale over a two-month period utilizing an extended Solomon Four-Group Design, with and without the treatment. The scale was administered to 351 students from junior high and high school CVAE classes in Ector County (Odessa), Fort Stockton, and Midland Independent School Districts and alternative schools in Denton, Fort Stockton, Midland and Odessa, Texas. The self-concept scores were treated for significance by an analysis of variance. Findings were that all groups tested scored within the age range, junior high school CVAE students scored lowest, but not significantly lower (p > .05); and junior high school CVAE students, alternative school students, and high school CVAE students all had a slight increase in self-confidence scores over the two-month period. All null hypotheses were retained. It was concluded that, overall, junior high school CVAE students, former dropouts who returned to an alternative school, and high school CVAE students possessed positive self-concepts that were above the national mean for the scale; and that CVAE classes enhance the self-concept of academically disadvantaged students in Cooperative Education classes.

Angelo, James J. "Characterizing the vertical structure and structural diversity of Florida oak scrub vegetation using discrete-return lidar". Master's thesis, University of Central Florida, 2010. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/4539.
Texto completo da fonteResumo:
Vertical structure, the top-to-bottom arrangement of aboveground vegetation, is an important component of forest and shrubland ecosystems. For many decades, ecologists have used foliage height profiles and other measures of vertical structure to identify discrete stages in post-disturbance succession and to quantify the heterogeneity of vegetation. Such studies have, however, required resource-intensive field surveys and have been limited to relatively small spatial extents (e.g., less than]15 ha). Light detection and ranging (lidar) is an active remote sensing technology with enormous potential to characterize the three-dimensional structure of vegetation over broad spatial scales. In this study, discrete-return lidar data were used to create vertical profiles for over 500 vegetation patches on approximately 1000 ha of an oak scrub landscape in the Kennedy Space Center/Merritt Island National Wildlife Refuge area on the east-central coast of Florida. Nonparametric multivariate analysis of variance (NPMANOVA) tests detected significant differences among the profiles belonging to the four predominant land use/land cover (LULC) types in the study area. For the dominant LULC category (Herbaceous upland non-forested), pairwise NPMANOVA comparisons indicated that there were significant differences between vertical profiles for some of the distinct time since fire (TSF) values. Measures of vertical structural diversity (VSD) were calculated from the vertical profiles and then null, linear, and quadratic models relating VSD to TSF were compared via an Akaike information criterion (AIC) model selection procedure. As predicted by the Intermediate Disturbance Hypothesis, the quadratic model was the best model for the Herbaceous upland non-forested LULC category, but it explained less than 3% of the total variation in VSD.; When fire frequency was considered in conjunction with TSF for this LULC category, however, the model that was quadratic in both predictor variables was the best model among the candidates and explained over 6% of the total variation in VSD. These results support the Extended Keystone Hypothesis, which predicts that disturbance generates discrete structural patterns across landscapes, and the Intermediate Disturbance Hypothesis, since the VSD of the predominant LULC category was maximized at intermediate levels of fire disturbance (i.e., intermediate values of TSF and/or fire frequency). In addition to demonstrating the ability of discrete-return lidar to characterize the vertical structure of vegetation at the landscape scale, this research has potential management implications. Using the techniques developed in this study, practitioners can compare the vertical structure of managed ecosystems to reference natural systems to evaluate the efficacy of managed disturbance regimes.ID: 029094364; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.S.)--University of Central Florida, 2010.; Includes bibliographical references (p. 42-47).

Vreeland, Kathryn. "Exploring the Effects of Concussion on College Students Returning to Academic Demands". ScholarWorks @ UVM, 2017. http://scholarworks.uvm.edu/graddis/748.
Texto completo da fonteResumo:
While the media frenzy focuses on the physical risks of concussion, there is also growing concern about the academic repercussions for students who sustain the injury. We do not currently have a uniform evidence-based approach for optimally returning a student back to learning activities after a concussion. We also do not understand how the diverse consequences of a concussion may affect academic self-efficacy and performance. The purpose of this study is to explore the effects a concussion may have on college students who are navigating the return to learn (RTL) process. This research aims to inform whether there are measureable deficits in academic self-efficacy using the previously validated and abridged survey measure, the Self-Efficacy of Learning Form (SELF-A). Time of injury during the academic semester is also considered, as we hypothesize greater healing should negate the concussion's effects on the measure of self-efficacy. In addition, the research explores students' experiences with RTL using a semi-structured interview approach.
The results suggest that college students who suffer a concussion during an academic semester have lower measures of academic self-efficacy compared to a control group of their peers. In addition, results show that students are returning to learn while still suffering from the effects of their concussion. This study found no significant correlation between the healing time of a concussion and the scores on the SELF-A. The interviews served to underscore the diverse myriad physical and psychological challenges a student faces, as well as the precarious variance in RTL strategies.
This study highlights the challenges that students face while they RTL following a concussion, and begs the investigation of whether better RTL practices can help mitigate the negative effects. It underscores the necessity for further research, evidence-based medical care, instructor accommodations, and institutional policies to support students' safe RTL and ability to perform at their maximal academic potential.

Texto completo da fonteResumo:
Dropping out of high school almost guarantees a life of hardship. The absence of a diploma contributes to poverty, increased crime rates and weakens the economy. To that end, school districts have a moral and ethical responsibility to bring an end to the dropout epidemic. This study was based on an analysis of more than 26,000 Brevard public school students. The researcher used 2006-2007, 2007-2008 and 2008-2009 student data to determine the relationship between race, grade level, ESE status, ELL status, SES, type of promotion and dropping out of school. In addition, the researcher reviewed Student Exit Survey data and face-to-face interview data to determine why students dropped out and identified strategies students felt would have kept them in school. Finally, individual interview data were analyzed to understand the circumstances that encouraged participants to return to earn their diplomas. The researcher recommended use of data management and tracking systems for early identification of potential dropouts so intervention could be delivered at the onset of failure, assignment of trained adult leaders to monitor and intervene for students; enforcement of compulsory school attendance; creation of mechanisms to reduce absenteeism that do not lead to school failure; required intervention for students who are truant; identification and assignment of highly effective teachers to at-risk youth; intervention in classrooms that have high rates of student failure; use of relevant curriculum and employment of instructional practices proven to increase engagement; alignment of intervention strategies with researched practices; gathering of input and feedback from students to determine program effectiveness; creation of meaningful exit interview processes; utilization of survey data to identify and remove school-related barriers and collaboration with community agencies to find meaningful and genuine solutions for students in crisis.ID: 029809063; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (Ed.D.)--University of Central Florida, 2011.; Includes bibliographical references (p. 283-291).

Texto completo da fonteResumo:
It has been widely documented that migrant labourers have made great contributions to the urban economy of China; as well, the explosive growth of rural-urban migrants has generated several "migration problems," such as growing social inequality in urban China. It is widely reported that a large number of migrants have returned to their places of origin, after several years of "urban life," and this trend has been accelerated after the global economic crisis after 2008. Consequently, the large number of return migrants have created many problems in the cities, such as labour shortage in the manufacturing industry, and also posed a huge challenge to the rural areas in the resettlement of these returnees. In sum, to understand both the migrants in destination cities and return migrants in their places of origin is of great importance for both urban and rural development in China.
The research so far, on the understanding of migrants' behaviour and labour market outcomes in a multi-phased migration process, seems highly controversial and therefore, insufficient. This study, based on migrant survey data collected in Fujian Province, and return migrant interview data collected in Sichuan and Jiangxi Provinces, explores migrant labour market outcomes in the cities, as well as their geographical differentiation; migrant return intentions, and their gender differentiations; return behaviour and the resettlement situations of actual returnees. The results show that the multi-phased migration process of rural migrants in China is synthetically shaped by macro, meso, and micro factors, and by the interactions between these factors. To be more specific, findings of this study indicate that migrant labour markets in urban China are largely geographically differentiated according to several regional characteristics. The study also finds that a large proportion of rural-urban migrants intends to return to their places of origin. As well, their return intentions are significantly gender-differentiated. Finally, the resettlement situations of return migrants are closely connected to their migration experience.ix, 160 leaves : ill. ; 29 cm

Texto completo da fonteResumo:
Relationships among demographic, socioeconomic and person factors and Opioid Use Disorder diagnosis, treatment, and recidivism were explored. Data from a sample of 4,860 adults with substance use difficulties were analyzed. A program evaluation was conducted on Gateway Community Services to explore the use of Medication Assisted Treatments (MATs) and Psychosocial (PS) treatments to address Opioid Use Disorder. Using archival data, a chi-square analysis and independent sample t-test was performed. The results expressed that a relationship among race, type of substance use diagnosis, and treatment type and recidivism rate was found. While White/Non-Hispanics adults were more likely to use heroin than any other racial/ethnic backgrounds, gender differences were also found. Finally, frequency and duration of a combined treatment (PS + MAT) were negatively related to recidivism with no determination of previous prescription opioid use to be examined at this time.

The ability to predict stock returns is an ability many wish to possess, and in an accurate way as possible. For many years there has been an interest in the field of factor models explaining the returns, with the aim to increase the explanatory power. This is however a complex business since the factors and their improvement of explanatory power need to be significant. Now and then, researchers come up with new significant factors that have a positive impact on models. AQR Capital Management is no exception to this, since they in 2013 presented the factor Quality Minus Junk, earning significant risk-adjusted returns. This bachelor thesis work within mathematical statistics and industrial engineering and management, aims to investigate whether or not the commercial multi-factor model used at the public pension fund Fjärde AP-fonden will be improved by adding the factor Quality Minus Junk, in the sense of explanatory power. The method used is mainly based on multiple linear regression and three three-year time periods are studied ranging from 2010 to 2018. The results from this thesis work show that the QMJ factor provides significant increases in explanatory power for one of three time periods, the most recent period 2016$-$2018. However, since the results are inconclusive further studies are needed in order to better understand how to interpret the results and whether or not to include the QMJ factor in the model.Förmågan att förutsäga aktiers avkastning önskar många besitta, och på ett så precist sätt som möjligt. Under många år har forskning pågått inom området för faktormodeller som förklarar avkastningar, med målet att öka modellernas förklaringsgrad. Detta är dock en komplex verksamhet eftersom faktorerna och deras förbättring av förklaringsgraden måste vara signifikanta för modellen. Då och då kommer forskare fram med nya sådana faktorer som har positiv påverkan på modeller. AQR Capital Management är inget undantag eftersom de 2013 presenterade sin faktor Quality Minus Junk som visar signifikanta riskjusterade avkastningar. Detta kandidatexamensarbete inom matematisk statistik och industriell ekonomi, ämnar att utreda huruvida den kommersiella faktormodellen som används på Fjärde AP-fonden förbättras genom tillägget av faktorn Quality Minus Junk, i förklaringsgradsmening. Metoden som används är till största delen baserad på multipel linjär regression och tre treårsperioder studeras i tidsintervallet 2010 till 2018. Resultaten från detta projekt visar på att faktorn Quality Minus Junk bidrar med signifikanta ökningar av förklaringsgraden för en av tre perioder, den senaste perioden 2016-2018. Eftersom resultaten är inkonklusiva krävs vidare studier för att bättre förstå och konkludera vad dessa resultat faktiskt innebär samt för att inkludera QMJ-faktorn i modellen eller ej.

Texto completo da fonteResumo:
As hydrological computer modeling software continues to increase in complexity, the need for further understanding of the value of different model input datasets becomes apparent. Frequently used precipitation model input include rain gauge data and next-generation radar–based (NEXRAD) rainfall data. Rain gauge data are usually interpolated across a model domain using various methods including the Thiessen Polygon methodology, which may be data-sparse in some areas and overly data-dense in others. However, rain gauge data are generally very easy to use in hydrologic model development, often requiring little to no data processing. NEXRAD data have the potential to improve hydrologic runoff estimates due to the increased spatial resolution of the data: but has its own issues regarding accuracy, false precipitation indications, and difficulties due to data processing. Previous studies have investigated the value of NEXRAD input versus traditional rain gauge data inputs for hydrologic studies; however, results are inconclusive as to which precipitation source provides more accurate results. Limited work has been done to compare the value of these datasets at multiple spatial scales, especially in Florida, a study area dominated by low topographic drive and sub-tropical weather. In addition, little to no research has been done regarding the value of NEXRAD versus rain gauge data inputs at different rainfall return frequencies. The proposed research will utilize a hydrological rain-runoff model (HEC-HMS) of the Upper St. Johns River Basin, Florida to compare the performance of the two precipitation data input types at various watershed spatial scales and rainfall return frequencies. Statistical analysis of the hydrological model “goodness-of-fit” results will be utilized to assess the watershed scaling and rainfall frequency requirements to xii which NEXRAD data provide little to no advantage over standard rain gauges using the Thiessen Polygon method for estimating rainfall totals across a model domain.

Texto completo da fonteResumo:
Objectives To examine the relationship between Concussion Symptom Clusters (CSCs) and return-to-play time using a representative sample of U.S. college athletes with sports-related concussions.
Background Recent evidence regarding concussion symptoms have been observed to be an important element of concussion severity, and potentially a predictor of return-to-play time. However, there is a paucity of data examining the associations between Concussion Symptom Clusters (CSCs) and return-to-play time in the U.S. college athlete population.
Methods Data from the 2009-2010 to 2013-2014 academic years (n=1670) were obtained from the Datalys Center for Sports Injury and Prevention Inc. database. Exploratory factor analytic methods were applied, and the resulting factors were used in multinomial regression modeling to identify associations between CSCs and return-to-play time.
ResultsA 4-factor solution accounted for 48.8% of the variance and included: audio-vestibular, somatic, amnesic, and affective factor structure. Audio-vestibular symptoms were associated with increased odds of prevented participation at 7-13 days, 14-29 days, greater than 30 days, and out for remainder of season, respectively (p
Conclusion Specific CSCs were significantly associated with return-to-play time in college athletes, (p<0.05).

Entre 2005 y 2010 cerca de 1.4 millones de inmigrantes mexicanos regresaron a México. Aunque las razones de su regreso varían, es innegable que hay una creciente tendencia en lo que ahora es conocido como migración de retorno (MATT, 2014). Esta investigación cualitativa, tiene como propósito identificar características del desarrollo de lenguaje (español e inglés), el desarrollo social y el capital académico de los estudiantes con experiencia educativa previa en los Estados Unidos de América y que están inscritos en las escuelas de Sonora. Estudiantes y padres de familia que por un periodo de tiempo vivieron en ese país y ahora residen en tres distintas ciudades de la entidad dan su testimonio y, junto con el de los profesores se analizan las implicaciones educativas de esta migración de retorno bajo la perspectiva del transnacionalismo. Se busca volver visibles a estos estudiantes que cada vez adquieren mayor presencia en nuestras aulas, a través de la valoración de su capital social y académico y hacer propuestas educativas pertinentes acorde a sus necesidades multiculturales. Se reconocen las particularidades propias de esta región Sonora-Arizona, permiten por sus características geográficas, económicas y sociales, generar un enfoque enriquecido de redes transnacionales en favor del fortalecimiento de la identidad, el desarrollo económico y social. (Between 2005 and 2010 about 1,4 millions of people of Mexican immigrant returned to Mexico. Although their reasons are different, it is undeniable a growing tendency in what nowadays is known a return migration (MATT, 2014). This research aims to recognize qualitatively the social and language (Spanish and English) development, along with the academic value in students in Sonora who have had previous schooling experience in the United States of America. Students and parents who lived for a period of time in the US and now they live in three different cities in Sonora are some of the participants. Through their testimonies along with teachers this research explains the process of return migration to Mexico linked to the approach of transnationalism. The study focuses in making visible the increasing presence of these students in Mexican schools by giving value to their social and academic capital, as well as introduces educational proposals that are suitable to the student’s multicultural needs. The geographic, economic and social characteristics of the Sonora-Arizona region allows and generates a focal point abundant of transnational networks that favors the enrichment of identity, social and economic development.)

Texto completo da fonteResumo:
This thesis provides new insight into the EMU’s impact on the Euro-area firms’ performance, by examining the firms’ accounting rates of return and financial cash flows. The impact is evaluated separately for the EMU formation and the physical Euro adoption, and over different time horizons. The existing literature does not directly examine these issues.
This study uses the regression model of the difference-in-differences approach to examine 121 Euro-area and North American firms, covering 14 sectors, over the period from 1992 to 2008.
The results indicate a positive impact of the EMU on the firms’ financial cash flows, especially after the Euro adoption, which support the related literature. However, the accounting rates of return suggest a mostly negative impact. The magnitude of the impacts declines over time. The results are robust with respect to GDP as a control variable. The study also reports the EMU’s impact on 4 major industrial sectors.viii, 68 leaves : ill. ; 29 cm

Stewart, Calvin. "A Hybrid Constitutive Model For Creep, Fatigue, And Creep-Fatigue Damage". Doctoral diss., University of Central Florida, 2013. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/6023.
Texto completo da fonteResumo:
In the combustion zone of industrial- and aero- gas turbines, thermomechanical fatigue (TMF) is the dominant damage mechanism. Thermomechanical fatigue is a coupling of independent creep, fatigue, and oxidation damage mechanisms that interact and accelerate microstructural degradation. A mixture of intergranular cracking due to creep, transgranular cracking due to fatigue, and surface embrittlement due to oxidation is often observed in gas turbine components removed from service. The current maintenance scheme for gas turbines is to remove components from service when any criteria (elongation, stress-rupture, crack length, etc.) exceed the designed maximum allowable. Experimental, theoretical, and numerical analyses are performed to determine the state of the component as it relates to each criterion (a time consuming process). While calculating these metrics individually has been successful in the past, a better approach would be to develop a unified mechanical modeling that incorporates the constitutive response, microstructural degradation, and rupture of the subject material via a damage variable used to predict the cumulative “damage state” within a component. This would allow for a priori predictions of microstructural degradation, crack propagation/arrest, and component-level lifing. In this study, a unified mechanical model for creep-fatigue (deformation, cracking, and rupture) is proposed. It is hypothesized that damage quantification techniques can be used to develop accurate creep, fatigue, and plastic/ductile cumulative- nonlinear- damage laws within the continuum damage mechanics principle. These damage laws when coupled with appropriate constitutive equations and a degrading stiffness tensor can be used to predict the mechanical state of a component. A series of monotonic, creep, fatigue, and tensile-hold creep-fatigue tests are obtained from literature for 304 stainless steel at 600°C (1112°F) in an air. Cumulative- nonlinear- creep, fatigue, and a coupled creep-fatigue damage laws are developed. The individual damage variables are incorporated as an internal state variable within a novel unified viscoplasticity constitutive model (zero yield surface) and degrading stiffness tensor. These equations are implemented as a custom material model within a custom FORTRAN one-dimensional finite element code. The radial return mapping technique is used with the updated stress vector solved by Newton-Raphson iteration. A consistent tangent stiffness matrix is derived based on the inelastic strain increment. All available experimental data is compared to finite element results to determine the ability of the unified mechanical model to predict deformation, damage evolution, crack growth, and rupture under a creep-fatigue environment.Ph.D.

Este estudo investiga o sucesso no processo de bilinguismo português/japonês de seis jovens retornados do Japão. Como sucesso no bilinguismo, entendemos pelo caso em que o indivíduo, mesmo após uma longa permanência no Japão e vivência no sistema escolar japonês, tenha conseguido após o seu retorno no Brasil, manter o domínio na lingua japonesa e possuir uma proficiência linguísitica em português suficiente para seu ingresso no ensino superior brasileiro. O referencial teórico sobre bilinguismo foi baseado nos estudos de Skutnabb-Kangas (2008); Cummins (1984); Baker (1993); Nakajima (2010). Foram realizadas entrevistas semiestruturadas presenciais e online, sendo analisados os seguintes três domínios na trajetória de vida desses colaboradores que, baseados em uma auto-avaliação, foram divididos em 2 grupos bilíngues dominantes em português e bilingues dominantes em japonês : (1) ambiente linguístico no Japão (2) atitudes dos colaboradores com os estudos da L1 e L2 e (3) ambiente linguístico no Brasil. O estudo comprovou que o apoio de familiares e de terceiros constitui um fator importante na motivação dos estudos, bem como na superação de desafios surgidos na adaptação linguística e cultural. Foi também observado que os colaboradores de ambos os grupos tiveram que investir na aprendizagem da língua por um longo período para o desenvolvimento da proficiência linguística acadêmica ALP (Cummins, 2001; 2011) até o ingresso na faculdade. Em relação à rede de apoio formal, foram verificadas as seguintes ações para minimizar os problemas relacionados ao não domínio da língua japonesa no contexto de imigração no Japão: ingresso em escola pública de região com alta concentração de brasileiros, ingresso em faculdade japonesa por programa especial para retornados e ingresso em escola brasileira ações essas realizadas pelos colaboradores do grupo dominantes em português. Por outro lado, os do grupo dominantes em japonês utilizaram as seguintes medidas para facilitar a adaptação linguística e escolar no Brasil: ingresso em escola privada com curso curricular de japonês, ingresso em escola técnica e ingresso em escola pública estadual. Em ambos os grupos foi observada a frequência em cursos preparatórios pré-vestibular. Concluiu-se que o uso dessas redes de apoio formais infuenciou positivamente no desenvolvimento da ALP dos colaboradores.The study herein aims to investigate success in the process of Portuguese/Japanese bilingualism of six youngsters returned from Japan. In our view, successful bilingualism happens in those cases in which even after a long stay in Japan along with an experience with the Japanese school system, the individual has managed to keep his mastery of the Japanese language after returning to Brazil, and be proficient enough in Portuguese so as to be admitted to Brazilian higher education. The theoretical framework on bilingualism was based on studies of Skutnabb-Kangas (2008); Cummins (1984); Baker (1993); Nakajima (2010). Both in-person and online semi-structured interviews have been conducted focusing on three aspects in the life trajectory of interviewees who, based on self-evaluation, have been divided into two groups: Portuguese-dominant bilinguals, and Japanese-dominant bilinguals: (1) linguistic environment in Japan (2) attitude of interviewees with the study of both L1 and L2; and (3) linguistic environment in Brazil. The study has proved that support both from family and others is key to generate motivation for studies, as well as to foment the overcoming of problems arising from both linguistic and cultural adaptation. It has also been observed that interviewees in both groups had to invest on language learning for a long period of time to develop academic linguistic proficiency ALP (CUMMINS, 2001; 2011) until they were admitted to college. As for the formal support network, the following actions aiming at alleviating problems concerning nonmastering of Japanese language in the context of Japanese immigration in Japan have been taken: admission to a public school in an area with a high concentration of Brazilian people; admission to a Japanese college by means of a program specially designed for returned, and admission to a Brazilian school, being all those actions taken by interviewees in the Portuguese-dominant group. On the other hand, those in the Japanese-dominant group have taken the following measures to facilitate linguistic and school adaptation in Brazil: admission to a private school with Japanese language in the syllabus, admission to a technical school, and admission to a state public school. Attendance to college entrance examination prep courses has been observed in both groups. it has been concluded that the use of those formal support networks has had a positive impact on the development of ALP of interviewees.

"How and why did MARS facilitate migration control? : understanding the implication of migration and refugee studies (MARS) with the restriction of human mobility by UK state agencies". Thesis, University of Oxford, 2011. http://ora.ox.ac.uk/objects/uuid:fd66b181-747d-4551-b6d2-8bf30741b835.
Texto completo da fonteResumo:
This thesis makes two related arguments regarding the academic field of migration and refugee studies (MARS) and the control of migration by UK state agencies. The first, and more empirical one, is that the former facilitated the latter: the field’s members provided symbolic, technical, and pedagogic assistance to two non-departmental public bodies in controlling migration. The second, and more theoretical, argument of this thesis is that MARS facilitated migration control because of culture, power, and structure. It is through the field’s implication in the coercion of its human subjects by UK state agencies that MARS academics a) answered their calling, b) assisted class rule as ideologists, and c) separated sacred and profane by policing endogamy. The introduction describes the existing literature on the relationship between MARS and migration control. The consensus is that the former facilitated the latter. However, these studies fail to provide detailed accounts of the ways in which it did so. Chapter One defines the elements of my more empirical argument: MARS and migration control. An historical narrative outlines the institutional development of the field since its beginnings in the early 1980s. Then a new model for understanding migration control – i.e., migrant CODAR – is described. Chapter Two uses this model to trace the actor network through which MARS academics facilitated the restriction of their human subjects’ mobility by the UK state agencies of the Advisory Panel on Country Information and the Migration Advisory Committee. Chapters Three, Four, and Five use Weberian, Marxist, and Durkheimian anthropological approaches (respectively) to explain the implication of MARS and migration control that is described in Chapters One and Two. Finally, the conclusion of the thesis discusses its contributions to both more particular (i.e., the literature surveyed in the introduction on MARS and migration control) and more general (i.e., anthropology) scholarly fields.

The paper attempts to examine the effect of school quality on college graduates’ wage in Taiwan using 2002 College Graduate Survey, by examining whether returns to education are significantly different between academic and vocational 4-year colleges. To solve the sample selection problem, we use Heckman’s two-step correction procedure to correct self-selection for employment status. The multinomial logit model is applied to estimate the inverse Mill’s ratio and a wage equation is then estimated. The main findings of the paper suggest that the returns to vocational colleges are 2.31% lower than those to academic colleges. Therefore, given that the cost of attending a college is similar between academic and vocational colleges, academic colleges are a better investment in higher education than vocational colleges.
