Unravelling the organization

The application of a computer package for drawing cause maps (NETGRAPH) to a cause map originally given by Hall as part of a study of the ‘Saturday Evening Post’ is described. It is shown how the cause map produced by the computer reveals a number of subsystems. The way in which these can be more clearly revealed by manually redrawing the computer cause map is demonstrated. The subsystems thus obtained are shown to be identical to those given by Hall, except in one case where one of Hall's subsystems is split into two. It is suggested that this split is sensible from an organisational analysis standpoint. The organisational system is analysed in terms of a number of insights derived from the computer-produced cause map including its apparent lack of a formal model of the impact of the Magazine's decisions on the environment. Such a model is claimed by Beer to be indispensable, from a systems theory standpoint, to any ‘viable’ organisational system. The conclusions derived from this analysis are similar to those drawn by Hall, though they do extend his analysis in several respects. It is argued that the results show that the package is of potential use in analysing cause maps of organisations.     

A New Multidimensional Measure of Development: The Role of Technology and Institutions

This paper constructs four structural indices by using 42 socioeconomic variables for 129 countries and the 10 years period from 2003 to 2012. Each structural index can be considered as a measure of a certain dimension of development. The first two indices are the most useful in explaining gaps in development across countries. The first captures the role of technology and institutional quality while the second provides a measure of the basic level of development. The contrast between them signifies that the notion of development is not only multidimensional, but also changing with the stage of development. These two indices are combined to form a development index (DI). A comparison of DI to income per capita and the Human Development Index highlights the importance of institutions in the transition of countries from merely having high income to full development. A methodological contribution of the paper is to use a Jackknife approach within the factor analysis routine to test for the significance of the extracted factors/indices.     

Longitudinal Effects of Best‐Friend Communication Against Substance Use for Latino and Non‐Latino White Early Adolescents

Prior research examining peer influences on adolescent alcohol, cigarette, and marijuana use has primarily focused on the positive associations that peer substance use and offers have with adolescent use. Consequently, such research has often emphasized the negative influences of peers. This study, however, operationalizes peer influence through best‐friend communication against substance use and examines whether it indirectly protects against substance use by promoting anti–substance use norms. Structural equation modeling was utilized with longitudinal survey data from 277 Latino and 350 non‐Latino white 6th–8th‐grade‐students. For Latino and non‐Latino white students, best‐friend communication was indirectly related to alcohol and cigarette use through norms. Best‐friend communication also was indirectly related to marijuana use, but only for non‐Latino white students and for male students.     

An explorative study of peer influence and response to adolescent self‐cutting behavior in Hong Kong∗

This paper reports on a qualitative study of peer responses to self‐cutting of secondary school adolescents in Hong Kong. Through semi‐structured in‐depth interviews with three adolescent self‐cutters, their family members, and their peers, the peers’ response to adolescents’ self‐cutting was explored. The findings showed that different peers had different types of influence, as well as different responses to self‐cutting. Close and supportive peers were usually the first to discover the self‐cutting. They were a source of help, communicating with parents, friends, teachers, and the adolescents themselves. In contrast, non‐supportive peers, especially boyfriends or girlfriends, created conflicts that seemed to provoke self‐cutting. The findings’ significance for social work intervention is also discussed.     

The barriers to the effectiveness of culturally sensitive practices in health and social care services for Chinese people in Britain

This paper studies the problem that health and social care practitioners, intending to satisfy their ethnic minority users’ cultural preferences, end up providing services against their wishes. In particular it points out that this problem is caused by over-emphasising two key assumptions of ethnic minority groups. The first assumption is that all members of the same ethnic minority group organise their health and social care according to their cultural principles. The second assumption is that their cultural principles are monolithic. Demonstrating that these two assumptions may not necessarily be applicable to all ethnic minority groups, this paper discusses the diverse strategies used by Chinese people in Britain to organise their health and social care, and the differences between their two important cultural principles, Taoism and Confucianism. In order to demonstrate to professionals and the Government that they should not over-emphasise these two assumptions and that they need to pay attention to ethnic minority groups’ diverse needs, the paper suggests that different ethnic minority groups may need to unite to increase their influence in the service provision process. However it also warns that this tactic may lead to the subordination of minority group interests in the articulation of those large groups.

     

Bayesian semiparametric reproductive dispersion mixed models for non-normal longitudinal data: estimation and case influence analysis

Semiparametric reproductive dispersion mixed model (SPRDMM) is a natural extension of the reproductive dispersion model and the semiparametric mixed model. In this paper, we relax the normality assumption of random effects in SPRDMM and use a truncated and centred Dirichlet process prior to specify random effects, and present the Bayesian P-spline to approximate the smoothing unknown function. A hybrid algorithm combining the block Gibbs sampler and the Metropolis–Hastings algorithm is implemented to sample observations from the posterior distribution. Also, we develop Bayesian case deletion influence measure for SPRDMM based on the φ-divergence and present those computationally feasible formulas. Several simulation studies and a real example are presented to illustrate the proposed methodologies.     

Predicting Human Papillomavirus Vaccine Intentions of College-Aged Males: An Examination of Parents' and Son's Perceptions

Abstract Objective: To examine male students' and their parents' human papillomavirus (HPV) vaccine communication in relation to males' willingness to discuss the vaccine with their health care provider and the likelihood of being vaccinated. Participants: Dyads (n = 111) of students and parents. Methods: Participants completed a HPV vaccine survey based on the risk perception attitude framework in 2009. Results: Male students' perceived susceptibility for HPV and self-efficacy to talk to their provider were directly related to their intention to discuss the HPV vaccine, and their intention was directly related to their likelihood of being vaccinated. Parents' perceived self-efficacy to talk to their son and response efficacy of the vaccine were directly related to their intention to talk to their son; however, parents' intention was not related to the likelihood of their son being vaccinated. Conclusions: College males may benefit from HPV vaccine educational programs that include communication skills training to discuss the HPV vaccine with their parents.     

Evaluating Housing Needs and Preferences of Generation Y in Malaysia

In Malaysia, housing providers affect the planning system as housing industry constantly evolves to meet homebuyer needs. Generation Y has exhibited dissimilar housing needs compared to Generation X and Baby Boomer. Thus, housing developers seek to identify the current needs for young homebuyers to avoid experiencing unsold properties. This research aims to identify the fundamental housing needs and psychographic characteristics towards their housing preferences and future planning demands. A quantitative survey was used for collecting data and a statistical analysis was performed to evaluate research outcomes. This research will help local housing developers to understand Generation Y needs and preferences for the future housing demand.     

Comparing k Cumulative Incidence Functions Through Resampling Methods

Tests for the equality of k cumulative incidence functions in a competing risks model are proposed. Test statistics are based on a vector of processes related to the cumulative incidence functions. Since their asymptotic distributions appear very complicated and depend on the underlying distribution of the data, two resampling techniques, namely the well-known bootstrap method and the so-called random symmetrization method, are used to approximate the critical values of the tests. Without making any assumptions on the nature of dependence between the risks, the tests allow one to compare k risks simultaneously for k 2 under the random censorship model. Tests against ordered alternatives are also considered. Simulation studies indicate that the proposed tests perform very well with moderate sample size. A real application to cancer mortality data is given.
