The population in the Central Bohemian manor of Škvorec from the middle of the 18th to the end of the 19th century. Abstract The aim of this study is to analyze the reproductive behavior (nuptiality, natality, female and male fertility, mortality) and the social structure of selected groups of the population of the Škvorec manor in the 18th and 19th century. The Škvorec manor which is located in the territory of today's Central Bohemia was an important agricultural area in given period. The complete nominal excerpts from parish registers were used to find numbers of all births, marriages and deaths. In addition to traditional historical- demography methods (especially the family reconstitution method and subsequent calculation of demographic indicators from family leaves), advanced statistical methods (survival analysis, Cox regression model) were also used for data analysis. These approaches are new in Czech historical demography and bring many advantages, which are presented in the work. The natural change of population development at the manor is compared with the Czech lands as a whole and in more detail with selected rural and urban localities. The results mostly correspond with the population development which was observed in the Czech lands. The number of inhabitants of the manor in the years...

台灣股市中下市公司之預測–歷史事件研究法蘇凡晴 Unknown Date (has links)
本論文主要目地是在研究財務比率對上市公司發生下市事件之預測。我們運用歷史事件研究法和Cox迴歸模型去研究上市公司發生下市事件之原因。同時,我們也針對Cox迴歸模型和Logit模型在發現對下市事件有顯著影響的財務比率作比較。 / This study applies the event history analysis and the Cox regression model to examine the causes of firm delisting, and also compares the performance of the Cox regression model with that of the logit model in detecting factors that have a statistically significant impact on the delisting event. The empirical results show that the hazard rate of firm delisting increases with the ratio of current liabilities to current assets, a binary variable indicating if the total liabilities of a firm is greater than its total assets, and a binary variable indicating if the net income of a firm was negative for the last two quarters, while the hazard rate of firm delisting decreases with increases in the firm size and the ratio of funds provided by operations to total liabilities.

Survival analysis and accession optimization of prior enlisted United States Marine Corps officersHoglin, Phillip J. 03 1900 (has links)
Approved for public release, distribution is unlimited / The purpose of this thesis is to firstly analyze the determinants on the survival of United States Marine Corps Officers, and secondly, to develop the methodology to optimize the accessions of prior and non-prior enlisted officers. Using data from the Marine Corps Officer Accession Career file (MCCOAC), the Cox Proportional Hazards Model is used to estimate the effects of officer characteristics on their survival as a commissioned officer in the USMC. A Markov model for career transition is combined with fiscal data to determine the optimum number of prior and non-prior enlisted officers under the constraints of force structure and budget. The findings indicate that prior enlisted officers have a better survival rate than their non-prior enlisted counterparts. Additionally, officers who are married, commissioned through MECEP, graduate in the top third of their TBS class, and are assigned to a combat support MOS have a better survival rate than officers who are unmarried, commissioned through USNA, graduate in the middle third of their TBS class, and are assigned to either combat or combat service support MOS. The findings also indicate that the optimum number of prior enlisted officer accessions may be considerably lower than recent trends and may differ across MOS. Based on the findings; it is recommended that prior enlisted officer accession figures be reviewed. / Major, Australian Army

D’un système à l’autre : facteurs de risque d’incidence LSJPA chez les jeunes pris en charge en protection de la jeunesse en raison de troubles de comportementPineau-Villeneuve, Catherine 08 1900 (has links)
Le but premier des services de protection de la jeunesse est de mettre fin à une situation de compromission et d’éviter que celle-ci ne se reproduise. Cependant, une meilleure connaissance des facteurs de risque d’incidence LSJPA chez les jeunes pris en charge en raison de leurs comportements problématiques permettrait de mieux identifier et ainsi, d’adapter les interventions chez ceux se révélant être les plus à risque de délinquance juvénile. La présente étude propose donc de décrire l’ampleur et le risque d’incidence c’est-à-dire, l’application d’une sanction ou d’une mesure en vertu de la LSJPA chez ces jeunes et de déterminer, parmi les facteurs associés au jeune et ceux inhérents à l’intervention, quels en sont les meilleurs prédicteurs. Pour ce faire, des données clinico-administratives des 16 centres jeunesse du Québec ont été utilisées. Ainsi, tous les enfants et adolescents dont le dossier a été fermé à la suite d’une première intervention en protection de la jeunesse en raison de troubles de comportement entre le 1er janvier 2005 et le 31 décembre 2009 ont été observés (N = 6 630). Des analyses de survie (modèle Kaplan-Meier) ainsi que des régressions de Cox ont été effectuées. Les résultats indiquent qu’un jeune pris en charge en raison de troubles de comportement a 39,7% de risque de migrer vers les services judiciaires pour adolescents dans les cinq années qui suivent la fermeture de son dossier. Sans grande surprise, les garçons présentent un plus grand risque que leurs homologues féminins. Il appert également que le risque d’incidence varie en fonction du sexe et de la présence de maltraitance lors de la prise en charge initiale. De plus, les facteurs associés à l’usager lui-même semblent avoir un impact plus important sur l’incidence que ceux associés à la prise en charge. Aussi, la récurrence dans les services de protection en raison de troubles de comportement mais également en raison de nouveaux éléments liés à la maltraitance sont au nombre des éléments à surveiller avec beaucoup d’attention puisqu’ils sont fortement liés à une migration vers la LSJPA. Les implications cliniques sont discutées et une ouverture sur de futurs travaux est faite. / Among children and youth who have been maltreated, several studies point to the elevated risk of developmental problems such as delinquency and justice system involvement. Presenting serious behavioral problems is a sufficient condition to receive child protection services (CPS) in the province of Quebec; this offers the opportunity to focus on this condition and on the role it may play or not in the subsequent risk of Youth Criminal Justice Act (YCJA) involvement. The primary role of CPS is to end an abusive situation and to prevent its recurrence. However, a better understanding of the risk factors that lead to an YCJA involvement would help to identify and to adapt interventions for those at greatest risk of juvenile delinquency. The aim of this study is to describe the risk of an YCJA event after a first intervention of CPS due to behavioral problems, and to determine the individual and intervention related factors associated with this YCJA involvement. Administrative data from 16 youth centers in the province of Quebec has been used. Thus, all children and adolescents who have had their file closed after a first CPS intervention due to behavioral problems between January 1st 2005 and December, 31st 2009 were observed (N = 6,630). Survival analysis (Kaplan-Meier model) and Cox regression analyzes were performed. The results indicate that youths in the sample present a 39.7% overall risk of YCJA involvement within the 5-year follow-up period. Boys present a higher risk of YCJA involvement than girls, an unsurprising result. It also appears that the risk varies by gender and the presence of co-occurrence of maltreatment at initial report. Individual risk factors seem to have a greater impact on YCJA involvement than those associated with the CPS intervention. Moreover, recurrences of CPS due to behavioral problems but also because of new information related to child’s maltreatment are particularly important since they are strongly associated with future YCJA involvement. Implications for theory, research, and practice are discussed.

Liquidity in the banking sector / Liquidité dans le secteur bancaireSalé, Laurent 24 November 2016 (has links)
Comme un déterminant de la survie d'une banque durant la crise financière de 2007/2008, la liquidité dans le secteur bancaire a depuis récemment représenté un défi pour les communautés financières et universitaires. Les trois articles présentés dans cette thèse portent sur les deux principales facettes de la liquidité dans le secteur bancaire: la détention d'actifs liquides (à savoir, la trésorerie et les ressources assimilées) et le processus de création de la liquidité dans les banques utilisé pour financer des prêts. Comme on le verra dans les articles, ces deux aspects de la liquidité peuvent être considérés comme les deux faces d'une même pièce. Je reconnais que la liquidité dans le secteur bancaire est liée à la création monétaire; cependant, cette thèse se concentre sur les deux précités aspects de la liquidité. Tout d'abord, cette introduction présente comment le concept de la liquidité a évolué dans la pensée économique dominante. La seconde partie considère le renouveau de la détention de cash qui a été observée depuis la crise financière de 2007/2008 dans le secteur bancaire. La troisième section examine les propriétés de liquidité. La quatrième section explore ce que nous ne savons pas sur la liquidité. La cinquième section identifie et sélectionne trois problèmes fondamentaux relatifs à liquidité et qui sont analysés dans les trois articles présentés dans thèse. La sixième et dernière section présente la méthodologie utilisée dans les trois articles pour répondre à ces questions. Chapitre 1 : “Why do banks hold cash ?". La détention de cash et assimilé cash par les banques détiennent est devenue un enjeu majeur depuis la crise financière de 2008 qui a démontré que la trésorerie retenue est un déterminant majeur dans les chances de survie des banques. Cet article examine les déterminants de la détention de cash banque en utilisant des données internationales pour la période 1981-2014. Sur la base d'un grand échantillon, nous documentons une augmentation séculaire de la détention de cash par les banques pendant une période de 35 ans. Nous apportons la preuve que la nature optimale dynamique de la détention de cash est rejetée dans le secteur bancaire. Ces résultats contrastent avec le secteur non bancaire, où la nature optimale dynamique de trésorerie est observée. Chapitre 2: “Does an increase in capital negatively impact banking liquidity creation?”. A partir d'un ensemble de données composé d'un panel de 940 banques cotées des pays européens, américains et asiatiques, cet article documente l'évolution de la création de la liquidité bancaire au cours d'une période de 35 ans (1981-2014). La preuve empirique confirme que les niveaux de risque et de capital jouent un rôle significatif et négatif dans la création de liquidité par les banques. Dans l'ensemble, les effets négatifs de l’augmentation de capital sur la création de la liquidité bancaire sont plus importants que les effets positifs sur la gestion du risque correspondant, ce qui suggère que les exigences de fonds propres imposées pour soutenir la stabilité financière affectent négativement la création de liquidités. Ces résultats ont de larges implications pour les régulateurs bancaires. Chapitre 3: “Positive effects of Basel III on banking liquidity creation”. Ce document évalue l'effet du cadre réglementaire de Bâle III sur la création de liquidité bancaire. Les résultats sont basés sur un ensemble de données de panel de banques américaines qui représentent environ 60% des prêts et dépôts américains sur une période de 7 ans (2009-2015), en plus de différence dans la différence et les méthodes de survie standard. Tous les composants de Bâle III pris ensemble, il existe des preuves empiriques que Bâle III a un effet positif sur la création de liquidité bancaire sur le marché américain, en particulier pour les grandes banques. Ces résultats ont de larges implications pour les régulateurs bancaires. / As one determinant of a bank’s survival during the financial crisis of 2007-2008, liquidity in the banking sector presents a challenge for the financial and academic communities and has recently become a central point of interest. The three articles presented in this thesis focus on the two main facets of liquidity in the banking sector: the holding of liquid assets (i.e., cash and assimilated resources) and the process of liquidity-creation in banks used to fund loans. As will be discussed in the articles, these two aspects of liquidity can be viewed as two sides of the same coin. I acknowledge that liquidity in banking is linked to the creation of money; however, this thesis focuses on the aforementioned two aspects of liquidity. First, this section presents how ideas about liquidity in the banking sector have evolved in mainstream economic thought. Second, it considers the revival of cash-holding that has been observed since the financial crisis of 2007-2008. Third, it discusses the properties of liquidity. Fourth, it explores what we do not know about liquidity. Fifth, it identifies the fundamental issues analyzed in the three articles. Finally, it presents the methodology used in the articles to address these issues. Chapter1: “Why do banks hold cash ?”. This paper investigates the determinants of bank cash holding by using international data for the period 1981-2014. The results do not seem to provide support for the substitutability hypothesis regarding the substitutive relation between cash and debt levels. Further, using the GMM-system estimation method, we find no support for the dynamic optimal cash model, suggesting that cash management in the banking sector is bounded by number of constraints that make it difficult for the agents to optimize their utility. Chapter 2: “Does an increase in capital negatively impact banking liquidity creation?”. From a dataset composed of a panel of 940 listed banks based in European, American and Asian countries, this paper documents the evolution of bank liquidity creation over a 35-year period (1981-2014). The empirical evidence confirms that risk and equity levels play a significant and negative role. Overall, the negative effects of equity increases on bank liquidity creation are more significant than corresponding positive effects on risk management, suggesting that capital requirements imposed to support financial stability negatively affect liquidity creation. These findings have broad implications for policymakers. Chapter 3: “Positive effects of Basel III on banking liquidity creation”. This paper estimates the effect of the Basel III regulatory framework on banking liquidity creation. The results are based on a panel data set of U.S. banks that represent approximately 60% of U.S. loans and deposits over a 7-year period (from 2009 to 2015) in addition to difference-in-difference and standard survival methods. All components of Basel III taken together, there is empirical evidence that Basel III has a positive effect on banking liquidity creation in the US market in particular for major banks. These findings have broad implications for policy makers.

Government Funding and Failure in Nonprofit OrganizationsVance, Danielle L. 15 March 2011 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / For nonprofit organizations, securing and sustaining funding is essential to survival. Many nonprofit managers see government funding as ideal because of its perceived security (Grønbjerg, 1993; Froelich, 1999). However, there is little evidence to support the claim that such funds actually make nonprofits more sustainable, and some research has even suggested that nonprofits receiving “fickle” government funds are more likely to fail (Hager et al., 2004). The primary purpose of this work is to examine the relationship between government funding and nonprofit failure. Its secondary purpose is to understand the relationships between failure, government funding, and the causes for failure suggested by previous research—instability of the funding source and low funding diversification.
To examine these relationships, I chose to use survival analysis and employed the Cox regression technique. Here, I analyzed the NCCS-Guidestar National Nonprofit Research Database, which archives nonprofit IRS filings from 1998 to 2003. This data set is noteworthy for its level of detail and its comprehensive nature. I found that organizations receiving government funding are less likely to fail, especially if this funding is part of a balanced portfolio. Organizations with higher percentages of nonprofit funding and organizations with less diversified overall portfolios do not. Furthermore, nonprofit organizations with less diversified portfolios were more likely to fail, and, among organizations receiving government funding, those with the highest percentage of their revenue from the government were more likely to fail than their counterparts with less funding.

顧客生命週期價值分析之實地實證研究-以某銀行信用卡部門為例陳怡君 Unknown Date (has links)
要創造顧客價值,首先需瞭解顧客。顧客是企業最重要的資產,企業應掌握該資產之性質與經濟意涵。本研究自此觀點出發,對個案公司之顧客資產提出四大問題:1.可能長期/短期往來客戶分辨及探討可能長期往來客戶是否一定是好客戶2.各區隔客戶的主要消費型態3.各區隔顧客與企業之獲利關係4.各區隔顧客之理財型態。本研究藉由此四大問題,串連時間、獲利與經濟行為構面進行分析與探討。本研究之資料取自某銀行信用卡部門二年期之月顧客資料。
本研究之發現說明如下:
1.以獲利與時間兩構面為區隔,發現長期往來之客戶不一定是好客戶。可能短期往來客戶亦有極佳之獲利潛能,但可能因為企業未能滿足需求或客戶有交換使用各家信用卡之行為、預算分配情況的影響,致使此類客戶未能成為忠實客戶,管理當局應深入調查這些顧客的行為,以利策略之擬定。
2.各區隔間有鮮明之行為特質。各區隔之所注重的消費層次不同,關心的議題可能不同,因此企業在行銷上注重的層面理應不同。
3.大多數之客群對獲利有顯著貢獻,顯示出大多數客戶是具有潛在利潤的客戶。
4.「一般交易需求者」為個案銀行之主要客戶,屬於極少拖欠帳款,或者是有支出預算之消費者,銀行只能自手續費獲利,因此,日常營運成本可能是關心重點,企業應力求成為此類顧客的主要銀行。 / Customer valuation is becoming a critical element in strategy development. It is built on the notation that the customer is the primary asset of the firm. The firm has a protfolio of customer assets that should be analyzed economically to determine their value to the firm. The four issues in this study relate to (1) identifying possible long-lived or short-lived customers and if those possible long-lived customers are necessarily profitable customers or not; (2) investigating consuming behavior of each segment; (3) understanding the profit relationship between the firm and customers; (4) establising financing behavior of each segment. This study is based on a monthly data from a large retail bank for two years.
Bellows are the illustation of the empirical findings in this study:
1. Duration and customer profitability are two good dimensions of segmentation. Long-lived customers are not necessarily profitable customers. Short-lived customers have great potential in profitability, too. The firm may not fulfill their needs. Those customers may be butterflies, i.e., they like to use different banks’credit cards. On the other hand, some customers may have budget for their spending. The firm must investigate this phenomenon deeply, so as to plan their marketing strategy.
2. Each segment concerns about different issues because they have distintive consuming behavior. So, the firm must have different marketing strategies for each segment.
3. There is positive association between customers and the firm's profitability in most of the segments. This reveals that most customers are profitable.
4. Tansistors are the domain customer type of the firm. They usually pay bills in time. Maybe, they have spending budget. The firm receives transation fees only. Under this condition, operation excellence is the key point. The firm must pay great efforts to become the domain bank of their customers.

Statistical inference for joint modelling of longitudinal and survival dataLi, Qiuju January 2014 (has links)
In longitudinal studies, data collected within a subject or cluster are somewhat correlated by their very nature and special cares are needed to account for such correlation in the analysis of data. Under the framework of longitudinal studies, three topics are being discussed in this thesis. In chapter 2, the joint modelling of multivariate longitudinal process consisting of different types of outcomes are discussed. In the large cohort study of UK north Stafforshire osteoarthritis project, longitudinal trivariate outcomes of continuous, binary and ordinary data are observed at baseline, year 3 and year 6. Instead of analysing each process separately, joint modelling is proposed for the trivariate outcomes to account for the inherent association by introducing random effects and the covariance matrix G. The influence of covariance matrix G on statistical inference of fixed-effects parameters has been investigated within the Bayesian framework. The study shows that by joint modelling the multivariate longitudinal process, it can reduce the bias and provide with more reliable results than it does by modelling each process separately. Together with the longitudinal measurements taken intermittently, a counting process of events in time is often being observed as well during a longitudinal study. It is of interest to investigate the relationship between time to event and longitudinal process, on the other hand, measurements taken for the longitudinal process may be potentially truncated by the terminated events, such as death. Thus, it may be crucial to jointly model the survival and longitudinal data. It is popular to propose linear mixed-effects models for the longitudinal process of continuous outcomes and Cox regression model for survival data to characterize the relationship between time to event and longitudinal process, and some standard assumptions have been made. In chapter 3, we try to investigate the influence on statistical inference for survival data when the assumption of mutual independence on random error of linear mixed-effects models of longitudinal process has been violated. And the study is conducted by utilising conditional score estimation approach, which provides with robust estimators and shares computational advantage. Generalised sufficient statistic of random effects is proposed to account for the correlation remaining among the random error, which is characterized by the data-driven method of modified Cholesky decomposition. The simulation study shows that, by doing so, it can provide with nearly unbiased estimation and efficient statistical inference as well. In chapter 4, it is trying to account for both the current and past information of longitudinal process into the survival models of joint modelling. In the last 15 to 20 years, it has been popular or even standard to assume that longitudinal process affects the counting process of events in time only through the current value, which, however, is not necessary to be true all the time, as recognised by the investigators in more recent studies. An integral over the trajectory of longitudinal process, along with a weighted curve, is proposed to account for both the current and past information to improve inference and reduce the under estimation of effects of longitudinal process on the risk hazards. A plausible approach of statistical inference for the proposed models has been proposed in the chapter, along with real data analysis and simulation study.
