Das Feuer kleiner Gruppen: Analyse der Entwicklungslogik und -dynamik eines Beratungsprozesses

The spark of small groups: An analysis of the developmental logic and dynamics of a consultancy process In the recent past large group interventions have gained increased attention in the systemic consulting literature. In contrast to this tendency, this paper focuses on the significance and effectiveness of small group interventions in business consultancy.Based on a qualitative analysis of a consultancy process, the effectiveness of small group change processes is documented here: Unlike large groups, small groups not only are far more likely to succeed in developing structures which differ from the existing organizational structures, they moreover are much more likely to develop a strong identity which helps them generate the power necessary for change. Especially in conflict situations and in situations where the pressures that are being put on an organization are increasing, small groups are more likely to maintain their identity, another crucial prerequisite for the initiation of a change process.The paper shows that consultancy systems, which differ in structure from the customer organization, are apt to serve as incubators for the development of strong groups within an organization. These small groups are able to push for organizational changes using conflicts process.     

On 3-Stage Clos Networks with Different Nonblocking Requirements on Two Types of Calls

Hwang and Lin introduced a new nonblocking requirement for 2-cast traffic which imposes different requirements on different types of coexisting calls. The requirement is strictly nonblocking for point-to-point calls among the 2-cast traffic, and is rearrangeable for genuine 2-cast calls. They conjectured that the 3-stage Clos network C(n,n,r,r,2n) satisfies the above requirement. We prove that C(n,n,4,r,2n) satisfies the above requirement.Supported in part by NSC91-2115-M009-002.Supported in part by the National Science Council under grant NSC91-2115-M009-010 and by the Li-Li-Tai-Yang Network Research Center of National Chiao Tung University.     

The third dimension in social casework: Mary E. Richmond's contribution to family treatment

This article traces the development of family group treatment as conceptualized by Mary E. Richmond (1861–1928). While the main course of social work was following the new individual psychology from Europe after World War I, Richmond was paving the path for a clinical approach that was not to be realized until 30 years later.This is a revised, abbreviated version of a presentation made by the author at a doctoral seminar on the casework roots of practice delivered in 1965 at the School of Social Work, University of Southern California.     

A comparison of confidence intervals generated by the scheffé and bonferroni methods

Simultaneous confidence intervals for the p means of a multivariate normal random variable with known variances may be generated by the projection method of Scheffé and by the use of Bonferroni's inequality. It has been conjectured that the Bonferroni intervals are shorter than the Scheffé intervals, at least for the usual confidence levels. This conjecture is proved for all p≥2 and all confidence levels above 50%. It is shown, incidentally, that for all p≥2 Scheffé's intervals are shorter for sufficiently small confidence levels. The results are also applicable to the Bonferroni and Scheffé intervals generated for multinomial proportions.     

Aggregation of Variables in Least-Squares Regression

I consider the properties of the estimator when the true model is y = β₁ x ₁ + β₂ x ₂ + u, but the restriction β₁ = β₂ = β is incorrectly imposed. I show that the probability limit of is a weighted sum of β₁ and β₂; the weights sum to 1 but do not necessarily lie in the unit interval, so plim need not be bounded by β₁ and β₂. Sufficient conditions for such bounding are derived. Certain changes in the moments of x ₁ and x ₂ have “perverse” effects on the weights. I illustrate the consequences of inappropriate aggregation of variables with an empirical example of the effect of research and development investment on productivity.     

Experimental Coastal Land Reclamation: Qianhai as a Case Interpreted

ABSTRACT

Informed by a Coasian transaction cost paradigm enriched by the concept of Schumpeterian innovations, this paper discusses the advantages of using experimental coastal reclamation of the sea to build new cities with a policy for fostering innovations. A new development area at the margin of Shenzhen in China, Qianhai, is used to demonstrate how urban expansion by urban sprawling in a megacity can be avoided by reclamation of marginal land as analytically less costly than along intra-marginal land and more suitable for experimentation for the type of megacity concept that Qianhai aims to achieve.     

Insight into Informant Discrepancies Regarding Psychosexual Functioning of Adolescents with and without Autism Spectrum Disorder

The private nature of psychosexual functioning leads adolescents and their parents to have different perspectives, which highlights studying parent–child informant discrepancies in this domain. We investigated informant discrepancy in psychosexual functioning, using the self‐report and parent report versions of the Teen Transition Inventory (TTI), of adolescents with autism spectrum disorder (ASD; 136 parent–child dyads) compared to adolescents from the general population (GP; 70 parent–child dyads). Significantly larger informant discrepancies exist in ASD dyads than GP dyads in most domains of psychosexual functioning, except for Body image, Sexual behavior, and Confidence in the future. It is important to use and pay attention to both informants, as discrepancies are relevant for both research and clinical practice regarding psychosexual functioning.     

Kinship Reconsidered: Research on a Neglected Topic

This article reviews the recent history of kinship research, noting the relative neglect of the topic in recent decades. The lack of scholarly and empirical work on kinship has been hampered by both the absence of survey and qualitative research on contemporary kinship practices. The author focuses on what is known and not known about how individual put into practice kinship in the standard, nuclear form of the family. There is surprising in attention to the ceremonial family and, little is know about how families draw boundaries and construct kinship on ritual occasions in the literature. The author concludes by suggesting research strategies for examining both how kinship is constructed and practiced in the United States and in other advanced economies.
