Mathematical problem solving, modelling, applications, and links to other subjects

The paper will consist of three parts. In part I we shall present some background considerations which are necessary as a basis for what follows. We shall try to clarify some basic concepts and notions, and we shall collect the most important arguments (and related goals) in favour of problem solving, modelling and applications to other subjects in mathematics instruction. In the main part II we shall review the present state, recent trends, and prospective lines of development, both in empirical or theoretical research and in the practice of mathematics instruction and mathematics education, concerning problem solving, modelling, applications and relations to other subjects. In particular, we shall identify and discuss four major trends: a widened spectrum of arguments, an increased globality, an increased unification, and an extended use of computers. In the final part III we shall comment upon some important issues and problems related to our topic.

China's Labor Question

The Honda workers’ strike in 2010 attracted world wide attention. It was one of thousands of labor disputes that happen every year in China, but it was the first major calling for the right of workers to represent themselves in collective bargaining. The question of representation is therefore the main topic of the book. The various contributors to this volume share the view that the Chinese party-state takes the protest against social inequality seriously. It has enacted many laws aimed at channeling dissatisfaction into safe channels. The implementation of these laws, however, lags behind and these laws do not include the right of freedom of association. Without this right, super-exploitation will persist and the system of labor relations will remain prone to eruptive forms of protest. The first part of the book provides an overview of the economic context of Chinese labor relations, the transformation of class-relations, the evolution of labor law, and government policies intended to set a wage floor. Based on extensive field research, the second part looks at the evolution of labor relations at the industry level. In the third part, the focus shifts to the Corporate Social Responsibility agenda in China. The final part looks at the connection between land reform and social inequality.

Visibility and Voice for Union Women

A new collection of Case studies about gender and trade unions in nine countries, ranging from Turkey to India, Brazil to Africa, the Philippines and New Zealand. Researched and written by insider/outsider union activists and officers, the book is the culmination of five years of collaborative research by the Global Labour University Gender and Trade Unions Research Group.

Quality Governance based on Enterprise Engineering Method and Six Sigma Approach

Enterprise Modeling (EM) is currently in operation either as a technique to represent and understand the structure and behavior of the enterprise, or as a technique to analyze business processes, and in many cases as support technique for business process reengineering. However, EM architectures and methods for Enterprise Engineering can also used to support new management techniques like SIX SIGMA, because these new techniques need a clear, transparent and integrated definition and description of the business activities of the enterprise to be able to build up, optimize and operate an successful enterprise. The main goal of SIX SIGMA is to optimize the performance of processes. A still open question is: "What are the adequate Quality criteria and methods to ensure such performance? What must we do to get Quality governance?" This paper describes a method including an Enterprise Engineering method and SIX SIGMA strategy to reach Quality Governance

Value Added by Quality Management

Abstract: Quality Management is an essential part of successful organisations. But the effect of it is mostly not directly visible. The effects are more indirect, and have a time lag till results appear. In today’s challenging times, all activities of an organisation have to proof their ability to add value. While Value Based Management is more focussed on financial value, other concepts and models like EFQM Excellence Model and Kaplan and Norton’s Balanced Score Card also point on values that are the basis and driver for financial success. Quality Management has to proof its effects on company values, and therefore the transacting mechanisms have to be identified and procedure to manage the process of Value Adding Quality Management has to be developed.

Management practices and challenges in smallholder indigenous chicken production in Western Kenya

The potential benefit of indigenous chicken (Gallus domesticus) production is still under-exploited in Kenya despite the efforts by different stakeholders to mainstream this production system as a pathway to rural development. The production system is often characterized by low input-low output productivity and low commercialization of the enterprise. This study which dwells on the current management practices and challenges faced by smallholder indigenous chicken farmers was conducted to gain insights into the underlying causes of production constraints. In Western Kenya women (76%) dominate the indigenous chicken production system. The flock composition consists mainly of chicks, hens and pullets (80%) which reflects their retention for production purposes. Less than half of the farmers access institutional support services such as extension, training, credit and veterinary services. In addition, indigenous chicken is largely reared in a low input-low output free-range system with only few farmers (24.2%) adopting management interventions as disseminated by extension service. To improve production and attain increased productivity, policy should focus on repackaging extension messages that considers farmers economic situations and strengthens collective action initiatives. Accessing joint input purchase and collective marketing of chicken products may further assist the farmers to increase profit margins.

Innovation, Creativity, and Positive Psychological Capital: Examining the Relationships in Adolescents, Employees and Entrepreneurs

Innovation ist für das Überleben von Firmen und die Entwicklung von Ländern wesentlich, weil sie entscheidend für einen erhöhten Marktanteil und wettbewerbsfähigen Vorsprung ist (Baer & Frese, 2003; Dodgson, Gann & Salter; George & Zhou, 2011; Kleysen & Street, 2001). Gleichzeitig steht Innovation in engem Zusammenhang mit Erkenntnisfortschritten (West & Altink, 1996). Konzepte, die mit Innovation zu tun haben, beinhalten innovatives Verhalten und Kreativität. Kreativität ist die Produktion von neuen und nützlichen Ideen (Amabile, 1998), und Innovation ist die Umsetzung dieser neuen und nützlichen Ideen (Amabile, 1998; West, 2002). Diese Dissertation besteht aus fünf Abhandlungen, die sich mit den beiden Bereichen des Managements und der positiven Psychologie beschäftigen. Im Einzelnen verbindet die Dissertation Forschungen aus dem Bereich der positiven Psychologie mit Forschungen der Innovation, wie auch der pädagogischen Psychologie, um Antworten auf Forschungsfragen zu finden, die sich damit beschäftigen, was es ist, das die Kreativität von Mitarbeitern, Unternehmern und Jugendlichen und ihr positives psychologisches Kapital steigert (PsyCap). Luthans und seine Kollegen (2007, S.3) definieren das psychologische Kapital oder PsyCap als „den positiven psychologischen Entwicklungszustand einer Einzelperson, welcher wie folgt beschrieben wird: (1) Selbstvertrauen haben (Selbstwirksamkeit), um sich Herausforderungen zu stellen und den notwendigen Aufwand aufzubringen; (2) Eine positive Attribution (Optimismus) in Bezug auf gegenwärtigen und zukünftigen Erfolg; (3) Ziele anstreben und, wenn notwendig, die Wege zu den Zielen ändern, um Erfolg zu erreichen (Hoffnung); (4) Im Falle von Problemen und Missgeschicken standhalten und wieder zurückkommen (Widerstandsfähigkeit), um Erfolg zu erreichen.“
