Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book aims to provide an overview of the labour market's benchmark macroeconomic models. The matching models of equilibrium unemployment are, in fact, the primary and most popular theoretical tools used by economists to evaluate various labour market policies and to study one of the key macroeconomic variables: the unemployment rate. It has been recognised that unemployment has also a structural nature which persists over the business cycle. The matching models, i.e. the models à la Mortensen-Pissarides, explain the co-existence in equilibrium of unemployment and vacancies through frictions in matching workers and firms. Furthermore, these models generate predictions that have the right direction: unemployment goes up in recession and down in boom, while job vacancies shift in the opposite direction. The central role of these models in imperfect labour markets has recently been confirmed by the 2010 Nobel Prize for economy awarded to the founders of this approach: Peter Diamond, Dale Mortensen and Christopher Pissarides. 64 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The recent breakthroughs in communication technologies have reintroduced the user to Internet. Media consumers became empowered with the capabality to produce, and will gradually shift from the traditional role of an audience to generate content, compete with mainstream media and construct new social and cultural realities. This is a new era where communication is reshaping the world, redefining responsabilities and bringing in new (dis)orders. The channels of social media, through which audiences are mostly active, seems to be vulnurable platforms where Noise is integrated with the message by default, resulting in a participatory form of control and a state of deindividuation as the user gradually merges in the group. Thin lines set boundaries between the diffusion of information and the fuel of confusion, the enhancement of innovativeness and the distribution of persuasion; sustaining social control and menacing social order. 56 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume explores the management of meetings, prompted by the growing concern and anecdotal evidences in Ugandan organizations that meetings had become unproductive.Meetings are perceived to be for fire fighting, have befallen into time wasters,their outcomes are mismanaged, and take valuable resources.Their relevance has increasingly come under question.The study examined policy framework,practices,preparation,processes and effect of external factors on managing meetings. From the findings organizations have policy frameworks for meetings with clear reasons for convening them.The preparation and process are affected by organizational, personal and external factors. Meetings are a key tool for consultation, communication,handling grievances and team building. Preparation and process issues like communication, venue setting, material needs, hidden agendas, lack of fair participation,inconsistencies, among others have shaped the opinion that meetings are not productive as expected.We recommend further scholarly investigations into this key function. Practitioners should assess how meetings are managed.The findings are useful to students of management,scholars and policy makers. 68 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Processing theories (Clahsen, 1984; Pienemann, 1997) have argued that the production of subordinate clauses is the last stage in the development of the second language learner. However, these theories did not refer to the relation between proficiency level and the production of complex syntax. Thus, more knowledge is required about the development of frequency and accuracy of complex syntax in EFL learners, and the relation between this development and proficiency level. Moreover, both second language and first language research (i.e. Salaberry& Lopez-Ortega, 1998) have revealed the impact of the discourse genre and task on the production of subordinate clauses, without adequate investigation of expository discourse. Hence, this book provides an exploratory study on the development of complex syntax across three proficiency levels of EFL learners through oral expository presentations. A number of syntactic indicators of oral development are revealed with different degrees of sensitivity towards the development of fluency, accuracy, and complexity. This monograph should appeal to English instructors, linguists, and professionals in oral assessment and linguists. 112 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -For several decades, Nigeria has witnessed a remarkable increase in its economy and revenue.The reason for this increase is attributable to the massive wealth which the country derives from the sale of oil and gas products. The importance of the oil and gas industry to Nigeria's economy can never be over-emphasised as the revenue derived from the industry remains useful across various sectors of the country. However, behind this glossy facade of socio-economic benefits and development, the oil and gas industry has posed a major epidemic in Nigeria especially in the host communities where the actual processes of oil exploration and production occur. Despite the contribution of the oil rich communities to the overall development of Nigeria, they have continuously been faced with under-development and various forms of human right abuses. Against this background, this book will discuss the overall harmful impacts of the oil and gas industry in Niger Delta. Focusing on the human right aspects it will discuss the various areas of human rights which are continuously impeded on as a result of the unregulated operation of the oil and gas industry in the Niger Delta. 64 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Merozoite surface protein MSP2 is avaccine candidate antigen of Plasmodium falciparum that is polymorphic in natural populations. In this study we aimed to investigate whether malaria infection in associated with anti-malaria specific IgG, using recombinant proteins derived from the two major allelic types of MSP2 and ABO blood group. The conclusion is the Higher anti-malarial IgG1, IgG3, IgG2 and lower levels of IgG4 were associated with reduced risk of malaria infection. IgG2 is activator of the classical complement pathway, Fc RIIa H131 is essential for handling IgG2 immune complexes. These data suggest that an MSP2 based vaccine should be designed to induce high level antibody responses against the different MSP2 types present globally in P. falciparum populations and that MSP2 could be combined with other P. falciparum antigens to form a multi-component malaria vaccine. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Applications in languages like C have heavy pointer usage and it happens that a pointer p may point to operands of an expression, i.e., it points to operand of an expression along some path. If the value contained in the pointer variable is modified then it may or may not kill the original value of expression depending upon the path taken. Thus we see that there is redundancy along some path. To remove this redundancy we will try to make the expression completely redundant. But the node containing the modification of value of pointer p will inhibit hoisting the expression out of that node. So, to remove the redundancy along all paths some code duplication has to be performed. But the cost of duplication performed may exceed the benefit derived from removing the redundancy. Thus, to get benefit from duplication, we duplicate the code only if redundancy along some frequently executed (HOT) path is being removed. Here, we present an approach to perform code duplication only if the optimization opportunity exists along some HOT path. Profile based points-to analysis is used to explore such redundancies and thus remove them. 76 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Clinical procedures that are conventionally guided by 2D x-ray imaging, may benefit from the additional spatial information provided by 3D image data. For instance, guidance of minimally invasive procedures with CT or MRI data provides 3D spatial information and visualization of structures that are not visible with x-ray. Since 3D imaging modalities may not be available during the procedure or require increased patient dose, it is desirable to use pre-interventional/preoperative 3D patient data for guidance that was obtained for diagnosis and treatment planning. To accomplish this, a relationship between patient and image data has to be realized. This relationship can be obtained by 2D-3D image registration. The aim of the research presented in this thesis is to evaluate the performance and limitations of 2D-3D image registration for diagnostic and interventional x-ray imaging, and to develop new methods to overcome these limitations. 116 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Different kinds of changes are occurring in the organizations for enhancing the work flow performances. Some of those changes are either continuous or episodic. These changes have been noticed as a catalyst to start the processes of unlearning and new learning at any level of the organization starting from the higher levels up to the grassroots levels. Talking about the change, the concept of the unlearning has primary connection with successful implementation of change. It has been noticeable in the health organization, where people often spend half of their lives not to welcome any new routines and demands of the connected tasks with such a change. As a result a numbers of psychological, social, cognitive and intellectual barriers and hurdles stand firm in unlearning the old ways.It has been observed in health organization that any new learning practices for operating on the new IT devices will have to occur when the unlearning starts at both the organizational and individual levels. 72 pp. Englisch.…

In developing countries the burden of injuries is expanding and new risks are also emerging. However, injury control has suffered historical neglect for many centuries probably because injury has been viewed as accidents a term which has the impression of inevitability. Public health approach to injury control and prevention involves four steps. The four steps are: determining the magnitude, scope and characteristics of the problem; identifying the factors that increase the risk of injury and disability and determining modifiable risk factors; assessing what measures can be taken to prevent the problem, by using the information obtained in the second step to pilot and evaluate interventions; finally implementing the most promising interventions on a broad scale. This work contributes to the first step using information obtained from Emergency Department in a hospital in a developing country. The significance of interpersonal violence and road traffic injuries is underscored. 64 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is an empirical fact that intonation meaning takes primacy over lexical meaning. As professional communicators, broadcasters are expected to be proficient in the use of intonation as what matters in verbal communication is not what you say but how you say it. This work examines some Nigerian broadcasters' mastery of English intonation patterns to find out their awareness of the functions of intonation in effective communication and the extent to which intonation affects their dissemination of information to the audience. The analysis of the data for the study reveals that they were deficient in the use of English intonation as the incorrect intonation patterns used by them adversely affected their effective dissemination of information to the audience. The work therefore concludes that the selected broadcasters were generally poor in the use of English intonation for effective communication. This book is a good reference material for all researchers and students who are interested in the use of English intonation in Nigeria, and indeed West Africa, as broadcasters are often looked up to as models, worthy of emulation, in matters of appropriate language use. 76 pp. Englisch.…
