Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work is an analytical exploration and evaluation of the concept of diversity. It springs from a concern that within the teacher education discourse there is an apparent deficiency regarding analytical effort toward challenging ordinary terms, their strong convictions, and categorical statements stemming from them. This exploration set out to accomplish three things: 1) to develop a common sense understanding of diversity; 2) to provide a thematic review of selected literature within the teacher education discourse; and, 3) to develop an original hybridized form of philosophical conceptual analysis referred to as a 'net-type' analysis. In the least, this exploration procures two interesting finds. The first find is that diversity s meaning can be understood in two dimensions, which is referred to as diversity s double helix. And second, diversity is a reference to some action that should be taken in light of the demographic considerations. 140 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The experiences of African immigrants to the United States of America are sparsely represented in the literature. Recent research has focused more on Latinos and Asian ethnic minority populations than on African immigrants. This research explored the relationship between Gender Role Beliefs and Marital Satisfaction among Ghanaian Immigrant Couples, a subgroup living in the United States who has been virtually ignored. Acculturation theory was introduced as a framework to facilitate understanding of the relationship between Gender Role Beliefs of Ghanaian Immigrant Couples and their level of Marital Satisfaction in the American culture. The author examined the variables; Gender Role Beliefs and Marital Satisfaction with a correlation predictive design using a cross-sectional survey technique of seventy-seven Ghanaian immigrant adult couples currently residing in the tri-state area of New Jersey, Delaware and Pennsylvania in the United States. Husbands were liberal in their Gender Role Beliefs compared to wives; however, the difference was not statistically significant. 136 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -While involving parties with varying preferences, interests and knowledge brings new types of know-how outside the firm's existing knowledge boundaries, thus facilitating diversity and the search' for high-value solutions in the technology landscape, it makes it more difficult to coordinate the parties' actions in a congruent manner. The central theme of this book is therefore the management of collaboration and conflicts between professional organizations in the context of New Product Development (NPD). This book particularly investigates several theoretical and empirical research questions relevant to managing collaboration and conflict both at the firm and at the project level. At the firm level, it studies why a firm should outsource (motivation), with whom to work (selection), and how to implement the collaboration (process and contracting). At the project level, it searches for the operational principles which lead to effective NPD execution in cross-organization collaborative projects. In addition, it applies a model to examine the organizational (signaling), financial (bonus) and behavioral (status) levers to coordinate internal parties in a cross-functional project. 144 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Recent research has suggested that vascular disease risk factors (VDRF) may contribute to cognitive impairment. The aim of this study was to determine the relative contribution of VDRF to cognitive functioning and activities of daily living in a community-dwelling cohort of individuals aged 75-90. Participants were questioned about cigarette smoking and alcohol consumption, and a neurologist gathered information about prior diagnosis of vascular risk factors (i.e., hypertension, hypercholesterolemia, diabetes mellitus, arrhythmia, coronary artery disease, congestive heart failure, transient ischemic attack, and stroke). Volunteers also completed a one-hour neuropsychological test battery and questionnaires about levels of pain, symptoms of depression, and ability to perform activities of daily living. Results showed that in this sample of relatively healthy elderly individuals, vascular risk factor burden did not reliably contribute to cognitive functioning or ability to perform activities of daily living. 72 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hematopoiesis is maintained throughout the lifetime of an organism by a specialized group of rare cells known as the hematopoietic stem cells (HSCs). These cells are defined by their ability to self-renew to give rise to similar daughter HSCs, and to differentiate into all the lineages of blood cells. The region where HSCs reside to fulfil these tasks is known as the stem cell niche. In a niche, neighboring subsets of cells and extracellular substrates house stem cells and provide specialized signals to modulate stem cell self renewal and progeny production. Many studies have identified key components of the niche required to maintain the HSCs in their primitive state. However, the exact location of the HSC niche is yet to be clearly identified. Understanding all of the interactions between the stem cells and their microenvironment may yield practical methods for manipulating stem cells to achieve therapeutic outcomes in various disease settings. 80 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Interest in public confidence in legal authorities has experienced a virtual explosion over the past 20 years. One of the important reasons is that public trust in legal authorities is often cited by policymakers to validate the legitimacy of existing practices and policies. Despite its importance, little attention has been given to analyze the global attitude toward the police and courts. Accordingly, Leechaianan strives to bridge the gap in the literature by analyzing the impacts of both individual- and country-level predictors on confidence in the police and courts across 36 nations. The main purpose of this study is to understand how five types of variables (i.e. country characteristics, demographic, social-bond, attitudinal, and media-consumption variables) influence confidence in the police and courts in a macro level. This book provides very informative discussion regarding what factors do and do not matter to the police and courts. Finally, the in-depth analysis should help shed some light on this specific topic and be useful to professionals in law enforcement area, students, scholars, and anyone else who may be interested in criminal justice. 168 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The globalization of the world economy has led to an increasingly important role of international transportation and supply chain management. In particular, container transportation and maritime trade are important parts of international transportation as about 90 percent of the world s cargo moves by container. Each year, about 16 million containers enter seaport container terminals in the United States. After September 11, 2001, special attention has been given to the vulnerability of container transportation to terrorist activities. This fact has made it impossible for the United States to ignore potential terrorists dangers and threats and the potential use of dangerous goods such as nuclear and radiological weapons at seaport container terminals. 116 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The contributions of women poets have seemed much less significant in the history of traditional Chinese literature. Among the relatively small number of famous women poets in China, Zhu Shuzhen (1135 -1180 ) is certainly worthy of discussion, but she has not received much critical attention, in part because of the lack of reliable biographical information. Although some of Zhu Shuzhen s poems have been seen by some scholars as disgraceful, it is nevertheless valuable to explore the inner world and poetic indications of the voice projected from the poems in an objective way. However, as the number of poems attributed to Zhu Shuzhen is large, despite living under an atmosphere that discouraged the writing of poetry by women, her name is undoubtedly significant in the development of female poetry. The aesthetic values in Zhu Shuzhen s original verse have been retained through the author's translations by selecting the best appropriate original versions in different editions. 284 pp. Englisch.

SMC need to know how to marshal their staff and company knowledge. A knowledge sharing (KS) environment must be gradually developed and grown . This book focuses on developing an implementation roadmap for KS in SMC. The 4 areas of KS focused on in this book are; the appropriate meaning of KS in a commercial context, the specific issues relevant to SMC in the context of KS, the circumstances that should prevail to allow people to share knowledge and effective methods of facilitating company learning. The discussion of the KS issues are based on the literature and the empirical data. This book establishes a yard stick to the development of a strategic KS roadmap to facilitate implementing the process of KS in SMC. SMC were selected because of a lack of research in the context of Knowledge Management (KM). This book is of benefit to companies who wish to understand the practical aspects of KM and KS and how to realise those benefits. The roadmap provides a staged, step by step guide to implement KS. This book explains the necessity of each stage and how it s implemented to maximum benefit. 156 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The high availability of technological systems like aerospace, defense, petro-chemistry and automobile, is an important goal of earlier recent developments in system design technology knowing that the expensive failure can occur suddenly. To make the classical strategies of maintenance more efficient and to take into account the evolving product state and environment, a new analytic prognostic model is developed as a complement of existent maintenance strategies. This new model is applied to mechanical systems that are subject to fatigue failure under repetitive cyclic loading. Knowing that, the fatigue effects will initiate micro-cracks that can propagate suddenly and lead to failure. This model is based on existing damage laws in fracture mechanics, such as the crack propagation law of Paris-Erdogan beside the damage accumulation law of Palmgren-Miner. From a predefined threshold of degradation, the Remaining Useful Lifetime is estimated by this prognostic model. Damages can be assumed to be accumulated linearly and also nonlinearly, furthermore, the stochastic influence is included. In this work, two main applications are considered: automobile and petrochemical industries. 240 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As children grow, they transition from home to school environments, where they acquire and master knowledge and skills, and develop an image of themselves as learners and develop several types of relationships with adults as they grow. As they enter and remain in school, these relationships expand from being solely with parents and caretakers to include their teachers. Due to the large amount of time children spend in school, it is important to examine and understand how the school environment and its affordances, and the relationships that children form while there, influence their lives and, especially, their academic success or failure. This book examines the influence of student-teacher relationships and teacher support on the academic achievement and satisfaction with school for K-5 students. The study used longitudinal growth modeling, specifically, cross-classified random effects modeling, to examine the effect of these relationships on students' performance. The results provide insights on how these relationships affect achievement of specific groups of students. 116 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -We investigate the existence of style drift within the hedge fund industry and examine the relationship between style drift and both the stages of the funds lives and the past returns. There are two key contributions made in this study. Firstly, we consider fund risk return profiles directly, rather than classifying funds by their self-described strategies. Secondly, we implement a K-Means clustering algorithm with correlation distance to classify strategy groups, unlike other studies which clustered on qualitative fund attributes. We report a number of interesting empirical findings. Style drift is present in the hedge fund industry, and certain groups are more prone to drift than others. Funds at the end of their lives display a significantly higher level of erratic behaviour compared to their behaviours at birth. Finally, poor past performance relative to peers induce funds to change their style more frequently. 96 pp. Englisch.

Many programs encourage study skills courses and seminars with the intent to increase students' ability to think critically, synthesize knowledge and build on previous knowledge with new knowledge learned. With this in view, the purpose of this study was to look at the effectiveness of a learning strategies seminar on first-year students' academic success, retention, and persistence. The participants were students who attended a small liberal arts college. Students were exposed to non-traditional learning methods that tapped into their own innate learning abilities that enhanced critical thinking,analysis, problem-solving, and memory abilities. A sample syllabus outlining content and a course proposal to offer the seminar as a credit-bearing course are also included. 96 pp. Englisch.

Yet church has been redefined by many men as the fishing hole, the hiking trail, the golf course, or a hammock with a good book. Though literally, recreation is the theologically solid concept of re-creation, many churches treat care for one s physical self separately from the care of one s spiritual self. In his own ambitions to grow his church with spiritual, yet active folks, Rev. Paul Koch found that alternative outlets for community are readily available, accessible, and, in fact satisfied his personal needs for relationship and personal growth often better than church did (and he was the pastor!). He sought answers from six men who regularly exercised at a YMCA. They were interviewed, their interactions documented and understandings of mind/body/spirit connections were investigated. His findings incorporate Biblical, theological, feminist and contemporary perspectives. It was determined that quests for fellowship, family, identity and goal setting are motivating factors in men s spiritual growth. The gym at the Y is examined as a rich site for pastoral theological explorations of men's longings for and practices of spirituality. 120 pp. Englisch.

Since the pioneer work of Sir G. I. Taylor in 1953, the study of solute transport in longitudinal direction has been extensively studied by different researchers. This book is written for the researchers and post graduate students who are working in the field of time-dependent convection-diffusion problems. A clear view on basic fluid dynamics is given in the first chapter of the book. Three research problems have been carefully chosen to understand the basic mechanism of solute transport phenomena in longitudinal direction, and to predict the dispersion coefficient, mean concentration distribution for all time period using finite-difference technique. 116 pp. Englisch.

A user group could be formed by the users of different domains with different infrastructures and managerial policies. Handling requests from a wide range of users from different domains becomes a challenge when attempting to accommodate all the differences. Service providers find it impossible to track all users in a Grid. Therefore, an access control mechanism that provides users appropriate access to the resources in a Grid is required. Role Based Access Control (RBAC) models have been demonstrated to be an effective and efficient approach to manage accesses in a computing system. Much has been done to adapt the RBAC concept to Grids and focus on the authorization and verification of the dynamic factors or contexts of a user. Some applications also allow administrators to change the policies during the authorization process, but they did not handle the authorization in real-time and on demand manner in a Grid. It is a critical authorization requirement for a Grid. Therefore, this problem motivated us to develop a new Dynamic Role Lease Authorization (DRLA) protocol for a Grid. 128 pp. Englisch.

Ferrimagnets have several sublattices with a finite resultant moment. However, they normally take complicated magnetic structures. Because of the complexity of the structures, the author applied the standard mean-field theory for mixed spin Ising ferrimagnets.The mean-field approximation is an adequate starting point as it describes cooperative phenomena in which the effect of the ordering interaction is represented by that of a mean field proportional to the average net magnetic moment of a magnetic system.In this work, we have examined the effect of a single-ion anisotropy as well as an applied magnetic field on the existence and location of a compensation temperature to clarify the characteristic features in a series of molecular-based magnets. So, our investigations predict the possibility of many compensation points at low temperatures depending mainly on the negative and positive values of both anisotropies, and some characteristic values of the external fields. 116 pp. Englisch.

In this study, we identified miR-215 as a potential prognostic biomarker and miR-129 as a potential tumor suppressor and a novel therapeutic target in colorectal cancer. We showed that miR-215 levels were significantly decreased in tumors compared with corresponding normal tissues in patients diagnosed with stage II or stage III colorectal cancer. Furthermore, we described a novel mechanism mediated by miR-129 to trigger apoptosis by suppressing a key anti-apoptotic protein, BCL2. The expression of miR-129 was significantly and progressively down regulated in colorectal cancer tissue specimens compared with the adenomas and normal control samples. More importantly, we demonstrated that miR-129 increased the cytotoxic effect of 5- fluorouracil, in vitro and in vivo.

The aim of this research was to develop a strategy for managing teacher migration in Southern Africa. In this study, the author analysed the statistical scope of teacher migration in Southern Africa, its causes, effects, and management. The results of the study revealed that teacher migration statistics and data were generally patchy and incomplete in Southern Africa; that international teacher migration in the region was driven by three main structural causes; and that teacher migration had both positive and negative effects on the education systems of Southern African countries, migrant teachers and their families. The findings further revealed that improving the management of teacher migration in Southern Africa required a systematic and coordinated approach involving sending and receiving countries. In this regard, the author proffers key principles, guidelines and a model for managing teacher migration in the region. This publication is an important resource for policy makers, practitioners, scholars and ordinary readers. 344 pp. Englisch.
