A study of internal migration in England and Wales

Abstract The main trend in urban/rural migration is a continuous gain, in net terms, of towns from villages and large cities. But this is a result of two distinct migration streams associated with the process of family formation. While before marriage there is positive net migration from villages to both large cities and towns (and from large cities towards towns), after marriage there is a tendency for couples to move towards villages. This is explained by the desire of families, particularly those belonging to the middle class to move out of the urban centres to better accommodation in smaller communities. Considerable variations in migrations within and into regions are observed. These reflect the continuation oflong-term trends in internal migration (as described in Part I of this paper) in particular, population dispersal from Greater London and larger distance migration into the Southern and Eastern regions. Some social characteristics of migrants and non-migrants are compared. Associations between the intensity of internal migration on the one hand, and occupational status, education, social mobility and family size on the other are observed. An attempt is made to assess the extent of migration associated with the marriage process. Although this process increases mobility, its relative contribution to total adult mobility appears to be only slight.     

Using expected values to simplify decision making under uncertainty

A simulation study examines the impact of a simplification strategy that replaces distributional attribute evaluations with their expected values and uses those expectations in an additive value model. Several alternate simplified forms and approximation approaches are investigated, with results showing that in general the simplified models are able to provide acceptable performance that is fairly robust to a variety of internal and external environmental changes, including changes to the distributional forms of the attribute evaluations, errors in the assessment of the expected values, and problem size. Certain of the simplified models are shown to be highly sensitive to the form of the underlying preference functions, and in particular to extreme non-linearity in these preferences.     

Half integer extreme points in the linear relaxation of the 2-edge-connected subgraph polyhedron

This paper studies the graphs for which the linear relaxation of the 2-connected spanning subgraph polyhedron has integer or half-integer extreme points. These graphs are called quasi-integer. For these graphs, the linear relaxation of the k-edge connected spanning subgraph polyhedron is integer for all k=4r, r≥1. The class of quasi-integer graphs is closed under minors and contains for instance the class of series-parallel graphs. We discuss some structural properties of graphs which are minimally non quasi-integer graphs, then we examine some basic operations which preserve the quasi-integer property. Using this, we show that the subdivisions of wheels are quasi-integer.     

Your money or your life: a new variation on the Heinz Dilemma

Millions of Medicare-age Americans are drug dependent, not because of addiction but because of common chronic health problems such as diabetes, heart failure, high blood pressure, and arthritis. Seniors are up in arms because drug company control of distribution and pricing of pharmaceuticals is eating away hard-earned nest eggs. Who cares? Where's the justice?     

Developing the Concept of Transparency for Use in Supply Relationships

Management concern surrounding the supply of goods and services from business to business, and the related attempts to understand the phenomena observed therein, appears to rest upon a broad range of incompatible perspectives, from political science (often limited to considerations of power) to the logistical (akin to manipulation of a great, benign but dynamic jigsaw puzzle). It appears that all perspectives abrade against the difficulties of exchanging information, knowledge and innovation within the relationships between buying and selling organizations and the apparent chronic systemic inefficiency that transactions often represent in this context. This article addresses these concerns, exploring the concept of transparency and the developments necessary for it to be useful in exchanging sensitive information and tacit knowledge in supply relationships. Our central concern is how the understanding of transparency and its commercial importance may change when it is expressed as a manageable element of the relationship between two organizations rather than as a general property of a broader system (e.g. a supply network, industrial sub-sector, geographical cluster) and what utility this differentiation might hold for managers. The conclusion to the article, and the implication for managers, is that transparency might indeed be created and usefully managed within supply relationships but that it would differ fundamentally in meaning from previously posited concepts, with the same name, in different contexts.     

Philosophie als Einübung des Perspektivenwechsels am Beispiel von Platon und Nietzsche

Philosophy as exercising the shift of perspectives, exemplified with Plato and NietzscheIn professional counselling a shift of perspectives is useful to develop new options of thinking and of action in the case of seemingly hopeless situations. Philosophy presents a great variety of concepts and also of models of change processes, which may offer a resource to counsellors. With regard to Plato’s “cave metaphor” and to Nietzsche’s “transvaluation of all values” the author presents a structure of change in three stages. Concerning the practice of counsellors some relevant aspects are derived from these discussions.     

Charisma,Macht und Narzissmus

Charisma, power and narcissism. On the diagnostics of an ambivalent leading qualityManagers are often obviously narcissistic personalities with “charismatic qualities”. The author discusses the background of these qualities and their ambivalence, because behind the brilliance of a successful manager may be a hidden narcissistic problem as the actual motive power. Nevertheless a constructive narcissism is to be distinguished from a destructive one. Charismatic constellations as well as narcissistic dynamics are to be understood not only as an individual problem but as an interactional phenomenon, involving both sides of a relationship. In order to explain these dynamics, the author presents the concepts of “narcissistic collusion” and “expanded self”. It is of great importance to the coach, to be able to analyse and to deal with these relational patterns — and also to preserve oneself from being involved in such narcissistic dynamics.
