TSENG, TZU-HUNG 15 July 2007 (has links)
Under the business environment in the 21th century with global competition and outsourcing cooperation, the model of starting an enterprise has been performed diversely. This study explores the elements of starting an enterprise that uses different methods of communication and marketing. In the field of direct selling, every distributor hopes to own a massive down-line organization with direct management in order to earn a huge amount of reward. However, to build a successful down-line organization demands professional knowledge and practical management skills. This research studies the operation of the successfully performed¡u6-4-2 system¡vby exploratory research. ¡u6-4-2 system¡voffers a set of models which is similar to the chain store operations of 100% copying and leads the partners to the same direction by offering operating modules and verifying methods that are simple, correct and success-assuring . This system sequentially improves the behavior and thinking method of a new member, cultivates his/her characteristics and abilities to become a leader. It has established an international multi-level marketing organization simply by two requirements to the distributors¡¦ daily life: following five major principles; doing seven things a day.

Design and fabrication of multi-level aspherical microlens for OLED

Hsu, Yi-ching 07 September 2009 (has links)
Organic light-emitting diodes (OLEDs) are regarded as next-generation light sources. The enhancement of external quantum efficiency of OLEDs has been investigated widely. It is an effective method of improving the external quantum efficiency, which destroys the phenomenon of total internal reflection inside the OLEDs by attaching microlens array to the surface of the glass substrate of the OLEDs. In this thesis, a multi-level aspherical gapless microlens array was designed and manufactured, and it was applied to OLEDs. In contrast with a spherical microlens array, the multi-level aspherical gapless microlens array can achieve a form of high aspect ratio and high fill factor, and they can enhance the external quantum efficiency of OLEDs. At first, aspherical microlens arrays with different parameters, including shapes of curved surface, layouts and feature dimensions, were simulated by optical simulation software, FRED. The aspherical microlens arrays which were attached to an OLED were simulated with a ray tracing method. Then, an optimal geometry and layout were found out. After simulation, a film with multi-level aspherical microlens array was fabricated by a LIGA-like process, including lithography, electroforming, PDMS (Polydimethylsiloxane) micro-molding and UV (Ultraviolet) -cured techniques. The characteristic in this process was to use multi-lithography to fabricate a microlens array with multi-level and high aspect ratio. The shape of multi-level was similar to the design, and the process can achieve the advantage of batch manufacture. Finally, the films with different multi-level aspherical microlens array were attached to an OLED to measure the optical-electric properties. The measured results were compared with simulation and confirmed them.

Formella förändringar i svensk sysselsättningspolitik : - En kvantitativ innehållsanalys av samvariationen mellan svensk sysselsättningspolitik och EU:s sysselsättningsstrategi

Lundmark, Lovisa January 2008 (has links)
<p>The intention of this study is to perform a content analysis based on a theoretical framework founded on multi-level governance, MLG. The thesis examines the formal changes within employment politics between 1999 and 2004 (Sweden´s action plan for employment) and 1998 and 2007 (the spring budget proposition). I will investigate how multi-level governance has effected the Swedish employment politics. Furthermore, the purpose of the thesis and the questions under consideration are: How have the formal structures within Swedish employment politics changed since Sweden’s admission to the European union, particularly during the periods 1997-2008 and 1999-2004? And: How do the changes in Sweden, together with the European union directive concerning employment, coincide in the so-called employment strategy?</p><p>While performing the analysis I have focused on multi-level governance. The method used is quantitative content analysis in order to explain the co-variation between Swedish employment politics and the employment politics of the European union - the employment strategy. The conclusions from the research are that there is a clear influence by the EU in Sweden, and between the two groups of documents is Sweden´s action plan for employment, which is more influenced than the spring budget propositions.</p>

A Multi-Grid Method for Generalized Lyapunov Equations

Penzl, Thilo 07 September 2005 (has links) (PDF)
We present a multi-grid method for a class of structured generalized Lyapunov matrix equations. Such equations need to be solved in each step of the Newton method for algebraic Riccati equations, which arise from linear-quadratic optimal control problems governed by partial differential equations. We prove the rate of convergence of the two-grid method to be bounded independent of the dimension of the problem under certain assumptions. The multi-grid method is based on matrix-matrix multiplications and thus it offers a great potential for a parallelization. The efficiency of the method is demonstrated by numerical experiments.

Fast solvers for degenerated problems

Beuchler, Sven 11 April 2006 (has links) (PDF)
In this paper, finite element discretizations of the degenerated operator -&omega;<sup>2</sup>(y) u<sub>xx</sub>-&omega;<sup>2</sup>(x)u<sub>yy</sub>=g in the unit square are investigated, where the weight function satisfies &omega;(&xi;)=&xi;<sup>&alpha;</sup> with &alpha; &ge; 0. We propose two multi-level methods in order to solve the resulting system of linear algebraic equations. The first method is a multi-grid algorithm with line-smoother. A proof of the smoothing property is given. The second method is a BPX-like preconditioner which we call MTS-BPX preconditioner. We show that the upper eigenvalue bound of the MTS-BPX preconditioned system matrix grows proportionally to the level number.

Governance, Functions, and Traits of European Transnational Municipal Networks : An evaluation by means of German Member Cities

Oppowa, Sascha January 2015 (has links)
As much as urban areas are centres of greenhouse gas emissions, cities hold a unique position in tackling climate change as they have legal authority over key sectors such as buildings, transportation, and urban planning. Recognising the benefit of coordinating activities on the local level, transnational municipal networks (TMNs) unite local governments across borders, providing particular services to its members. In Europe, there are several TMNs focusing on issues related to climate protection. This study examines four of these networks (ICLEI, Climate Alliance, Energy Cities, EUROCITIES) and the functions they hold available. Interviews were conducted with representatives from the networks and a sample of German cities in order to depict both their perspectives. In terms of functions provided by the TMNs as a whole, lobbying for needs and concerns of the municipalities was considered as one of the networks’ main task. Further, two forms of lobbying were identified that varied depending on the respective network: lobbying, including mayoral support; and lobbying on a technical level. In addition, interviewees valued the exchange of information and experiences that these networks enable and foster. Lastly, their role in project management was stated as an important reason for network membership. A TMN-specific analysis revealed that ICLEI’s main strength was seen in lobbying on international level for its members’ concerns by also involving its member cities’ mayors. Municipalities seemed to turn to Energy Cities and EUROCITIES with regard to lobbying concentrated at EU decision-making, project cooperation, and the exchange of information. Climate Alliance’s unique selling point – since none of the other networks was associated with this function – appeared to be in organising awareness raising events and campaigns in cooperation with its members.

The Social System of Guinea Baboons (Papio papio) With a Focus on Male-Male Relationships

Patzelt, Annika 27 June 2013 (has links)
Paviane (Papio spp.) gelten als wichtiges Modell für die Evolution menschlicher Sozialsysteme. Im Pleistozän hat sich die Gattung Papio ausgehend vom südlichen Afrika über große Teile Afrikas südlich der Sahara sowie Teile der Arabischen Halbinsel ausgebreitet, wobei Guineapaviane (P. papio) die nordwestlichsten und Mantelpaviane (P. hamadryas) die nordöstlichsten Gebiete besiedeln. Im Vergleich zu anderen Pavianarten, deren Ökologie und Sozialsystem seit vielen Jahrzehnten umfangreich untersucht werden, waren zu Guineapavianen bisher nur wenige und zudem widersprüchliche Kenntnisse vorhanden. Dies ist vor allem darauf zurückzuführen, dass von ihnen quantitative Freilanddaten fehlten. Bisher wurden für Paviane zwei Typen von Sozialsystemen beschrieben: Die sogenannten Savannenpaviane (P. anubis, P. cynocephalus und P. ursinus) im südlichen und östlichen Afrika leben in Gruppen mit mehreren Männchen und mehreren Weibchen, wobei Netzwerke nahverwandter Weibchen den sozialen Kern bilden. Mantelpaviane in Nordost-Afrika und Arabien leben dagegen in einer mehrschichtigen Gesellschaft, in denen Ein-Mann-Gruppen die kleinste soziale Einheit darstellen. Ergebnisse früherer Studien an Guineapavianen deuteten darauf hin, dass ihre Gesellschaft auch mehrschichtig ist, ähnlich der von Mantelpavianen. Allerdings wurden Guineapavianmännchen als untereinander außergewöhnlich tolerant beschrieben, was zu der Vermutung führte, dass ihr Sozialsystem innerhalb der Gattung Papio einzigartig ist. Zudem scheinen Männchen verschiedener Pavianarten bezüglich der Konsistenz ihrer Hierarchien, der Häufigkeit von Koalitionsbildung und Infantizidrisiko zu variieren. Diese Beobachtung führte zu der Vermutung, dass im Zusammenhang mit der Ausbreitung der Gattung über den afrikanischen Kontinent entlang eines Süd-Nord-Gradienten eine Evolution hin zu mehr Toleranz und Koalitionensbildung zwischen Männchen stattgefunden hat. Da Guineapaviane an der nordwestlichsten Grenze des Verbreitungsgebietes der Gattung leben, ist hier eine Charakterisierung der Beziehungen zwischen Männchen wichtig, um diese Annahme zu überprüfen. In meiner Dissertation habe ich verschiedene Aspekte des Sozialsystems der Guineapaviane untersucht. Dabei habe ich mich im Besonderen auf Männchen fokussiert, um zu prüfen, ob diese eine ähnlich einflussreiche Rolle in ihrer Gesellschaft einnehmen, wie es bei Mantelpavianmännchen beobachtet wird. Der Fokus auf Männchen erlaubte außerdem den angenommenen Süd-Nord-Gradienten bezüglich der Qualität der Beziehungen zwischen Männchen zu testen. Demnach sollten Guineapavianmännchen als Angehörige einer nördlichen Art im Vergleich zu südlicheren Arten toleranter und kooperativer untereinander sein. Da allgemein angenommen wird, dass Verwandtschaft einen bedeutenden Einfluss auf soziale Interaktionsmuster haben kann (Verwandtenselektion) und auch in sozialen Interaktionen zwischen Mantelpavianmännchen eine wichtige Rolle spielt, habe ich darüber hinaus geprüft, ob genetische Verwandtschaft die räumlichen und sozialen Interaktionsmuster von Guineapavianmännchen erklären kann. Meine Studie ist die erste über Guineapaviane, die überwiegend auf quantitativen Daten zum Sozialverhalten individuell bekannter Tiere in ihrem natürlichen Lebensraum basiert. Zu Beginn des Projektes haben wir nicht habituierte Guineapaviane untersucht, die zu einer Population (Community) von Tieren gehören, deren Streifgebiet sich in der Nähe unserer Feldstation im Niokolo Koba Nationalpark im Senegal befindet. Dazu notierten wir die Größe und Zusammensetzung von Untergruppen an einer Wasserstelle. Es zeigte sich, dass diese Untergruppen je nach Tages- und Jahreszeit sehr variabel in ihrer Größe sowie der Zusammensetzung verschiedener Geschlechts- und Altersklassen waren. Nachdem wir zwei Untergruppen habituiert hatten und die Tiere individuell unterscheiden konnten, wurden anhand räumlicher Daten von mit GPS-Sendern ausgestatteten Tieren sowie mit Hilfe von Verhaltensbeobachtungen soziale Interaktionen und räumliche Assoziationen zwischen adulten Guineapavianmännchen untersucht. Um den Einfluss von Verwandtschaft auf das Sozialsystem zu prüfen, haben wir zudem mehrere adulte Männchen aus der untersuchten Community genotypisiert und genetische Verwandtschaft mit räumlichen Gruppierungs- bzw. sozialen Interaktionsmustern in Bezug gesetzt. Die Ergebnisse meiner Arbeit deuten darauf hin, dass die soziale Organisation der Guineapaviane mindestens drei Ebenen umfasst: Sogenannte Parties bestehen aus drei oder vier adulten Männchen (plus mehrere Weibchen und deren Jungtiere). Innerhalb dieser Ebene fand der Großteil der Interaktionen statt und es wurden enge soziale Bindungen sowie Koalitionen zwischen Männchen beobachtet. Parties scheinen daher die zentrale Einheit der Guineapaviangesellschaft zu bilden. Zwei oder drei Parties formen eine Gang, innerhalb derer die Männchen enger miteinander verwandt waren als Männchen verschiedener Gangs. Allgemein waren soziale Interaktionen auf die Ebene der Gang beschränkt. Die Community stellt die dritte Ebene dar und umfasst alle Individuen, die im gleichen Streifgebiet leben. Im Unterschied zum Mantelpaviansystem scheinen daher Ein-Mann-Gruppen bei Guineapavianen keine Organisationseinheit darzustellen, wobei wir über die Verteilung von Vaterschaften noch keine Aussagen machen können. Die Analyse sozialer Interaktionsmuster in Bezug auf Verwandtschaft ergab, dass Guineapavianmännchen unabhängig von Verwandtschaft starke kooperative Bindungen miteinander eingehen und sehr tolerant sind, sowohl innerhalb als auch zwischen Parties. Männchen scheinen also aktiv zum Zusammenhalt der Gangs beizutragen und spielen daher eine wichtige Rolle in der Erhaltung der mehrschichtigen Gesellschaft in der sie leben. Außerdem interagieren Männchen weitaus häufiger freundlich miteinander als bei anderen Pavianarten. Im Einklang damit zeigt ein Vergleich von Körpermaßen innerhalb der Gattung, dass bei Guineapavianmännchen Merkmale reduziert sind, welche mit intrasexueller Konkurrenz in Verbindung gebracht werden. Die sozialen Beziehungen zwischen Guineapavianmännchen scheinen demnach entscheidend von denen der Männchen anderer Pavianarten abzuweichen. Zusammengefasst belegt meine Studie, dass die Vielfalt von Sozialsystemen bei Pavianen, insbesondere die Variation in der Qualität der Beziehungen unter Männchen, größer ist als bisher angenommen. Die Gattung umfasst demzufolge vermutlich mehr als zwei, und mindestens drei, verschiedene Typen sozialer Systeme. Während die mehrschichtige Organisation der Guineapaviane oberflächlich dem Mantelpaviansystem ähnelt, unterscheiden sich die sozialen Beziehungen zwischen Guineapavianmännchen bezüglich der Intensität und Häufigkeit freundlicher Interaktionen auffallend von denen anderer Mitglieder der Gattung Papio. Diese Beobachtungen passen zu einem angenommenen Süd-Nord-Gradienten hinsichtlich einer erhöhten Häufigkeit von Koalitionsbildungen und einer gesteigerten Toleranz zwischen Männchen und betonen somit einmal mehr, dass es wichtig ist, die Stammesgeschichte und historischen Umweltbedingungen der untersuchten Arten neben derzeitigen Umweltbedingungen in die Untersuchung sozialer Evolution einzubeziehen.

Multi-level party politics : the Liberal Party from the ground up

Koop, Royce Abraham James 05 1900 (has links)
The organizations of national and provincial parties in Canada are understood to be separated from one another. However, it is not known whether this separation extends to the constituency-level organizations of those parties. In order to provide a better understanding of how national and provincial parties are linked at the local level (if at all), this thesis describes and accounts for the local organizations of the national Liberal Party and the provincial Liberal parties in sixteen national constituencies selected from the provinces of British Columbia, Ontario, and New Brunswick. Information from interviews with local party activists and participant observation in the ridings is used to develop a continuum of constituency-level party organizations. Descriptions of the activist bases, constituency associations, and local campaigns in each riding allow for each local organization to be placed along this continuum between integrated local organizations, which share important linkages between the national and provincial levels, and differentiated local organizations, where no such linkages exist. The placement of local organizations along this continuum is accounted for by (1) similarities or differences between the national and provincial party systems in the three provinces studied; (2) the actions of incumbent members of the national Parliament and provincial legislatures; and (3) characteristics of the constituencies. The patterns identified lead to a classification of four types of local organizations – One Political World, Interconnected Political Worlds, Distinctive Political Worlds, and Two Political Worlds – that illuminate the different forms of linkages between national and provincial parties that exist at the constituency level. This examination of the local organizations of the Liberal Party calls into question the academic consensus on the separation of national and provincial parties in Canada. Instead, the Liberal Party is characterized as an unevenly integrated party, where the parliamentary and extra-parliamentary parties are separated from provincial counterparts, but where the national and provincial parties on the ground are oftentimes integrated.

Social and Spatial Determinants of Adverse Birth Outcome Inequalities in Socially Advanced Societies

Meng, Gang January 2010 (has links)
The incidence of adverse birth outcomes, such as low birth weight and preterm births, has steadily risen in recent years in Canada. Despite the fact that numerous individual and neighbourhood risk factors for low birth weight and preterm births have been identified and various person-oriented intervention strategies have been implemented, uncertainties still exist concerning the role that place and space play in determining adverse birth outcomes. In order to succeed in producing community-oriented health policy and planning guidelines to reduce both the occurrence and inequalities of adverse birth outcomes, the research presented in this thesis provides an approach to examining the pathways of various socio-economic, environmental, and psycho-social risks to LBW and preterm births. Using a modified multilevel binary-outcome mediational analysis method, case studies are conducted within three public health units in Ontario, namely the Wellington-Dufferin-Guelph Health Unit, the Windsor-Essex County Health Unit, and the Halton Region Health Unit. Different pathways are investigated given the available data and the theoretical assumptions of three health inequality pathway models, namely the behavioural model, the psycho-social model, and the materialist model, and the geographical and planning perspectives of health inequalities. A local spatial analysis process is also used to identify spatial clusters of incidence and to assess possible associated reasons in order to support public health polices and planning in community-oriented health interventions. Using Bayesian spatial hierarchical analysis and spatial clustering analysis, local clustering of high risks of adverse birth outcomes and spatial variations of associated individual risks within the study areas are identified. The analysis is framed around five hypotheses that examine personal vs. spatial, compositional vs. contextual, psycho-social vs. material, personal vs. cultural, and global vs. local effects on the determinants of adverse birth outcomes. The results of testing these hypotheses provide evidence to assist with multi-component multi-level community-oriented interventions. Possible improvements of current prenatal care policies and programs to reduce the spatial and social inequalities of adverse birth outcomes are suggested. Potential improvements, including early stage prenatal health education, local healthy food provision, and cross-sector interventions such as the combination of social mixing strategies with bottom-up community-based health promotion programs, are also suggested.

Teachers' experiences of workplace bullying and its effects on health :|bdeveloping a multi-level intervention programme / Jaqueline de Vos

De Vos, Jaqueline January 2012 (has links)
Workplace bullying is recognised as a major psychosocial stressor in various professions and can have severe effects on health. Teachers are distinguished as an occupational group that is severely affected by this phenomenon. The general objectives of this research study were to firstly investigate teachers’ experiences of workplace bullying and its effects on health, and secondly, to develop a multi-level intervention programme that can be implemented to address workplace bullying and its effects on health in this context. This research study was conducted in two phases. The biopsychosocial model was applied as a theoretical foundation in the first phase. Participants were sampled by means of informative and educational articles that were placed online and in printed media. Selection criteria were applied to sample a group that was representative of victims of workplace bullying. Ultimately, twenty-seven teachers were included in this study. A qualitative, phenomenological research design was used to explore teachers’ experiences of workplace bullying and its effects on health. Data was specifically gathered by means of semi-structured interviews and personal documents. Semi-structured interviews were audio-recorded and data was transcribed verbatim. Methods of Interpretative Phenomenological Analysis were applied to analyse and present the data. Findings were supported with verbatim quotes and a literature control. Teachers’ reports indicated that workplace bullying is mostly perpetrated by principals and that colleagues are often also involved in the process. Bullying behaviours were aimed at attacking the character, as well as the work of teachers. Organisational channels were often exploited to bully teachers. Certain behaviours were an infringement of teachers’ human and labour rights. Findings are also analogous to the theory and dynamics that is depicted by the biopsychosocial model. Escalating stress and trauma were reflected in teachers’ physical, psychological and social health. The experience of workplace bullying firstly impacted on their psychological health, which was also accompanied by various physical health problems. Major depressive episodes and/ or symptoms of depression were mostly reported. Some teachers also reported symptoms of posttraumatic stress disorder, complex-posttraumatic stress disorder, and panic attacks. Teachers’ ill-health experiences further negatively impacted on their social and professional relationships. The school organisation is affected. The result is teachers with a lost passion for the profession, lowered work performance, increased absenteeism, and teachers’ intention to leave the profession. Findings finally indicated that certain personal and organisational characteristics facilitate and sustain workplace bullying. Relevant literature, field notes during the research process and findings in the first phase of this study guided the development of a multi-level intervention programme for the South African teaching profession. Strategic intervention activities were suggested to address some of the causes, as well as the physical, psychological and social health effects of workplace bullying. A strategic and methodological approach to multi-level intervention was also developed and proposed. Strategic intervention activities were ultimately suggested for the professional, social/ community, individual/ familial, dyadic, organisational, managerial, and work group level. / Thesis (PhD (Educational Psychology))--North-West University, Potchefstroom Campus, 2013
