Identifying the Components of Social Capital by Categorical Principal Component Analysis (CATPCA)

Social Indicators Research - Social capital is a promising concept, widely used by social science researchers in analysing factors that contribute to the persistence of various economic issues....     

China and the Different Regional Approaches in Africa

African countries have a tiny share in the international economy and are not able to play more than a small role in the International Relations arena. Nevertheless, major players are looking at Africa with a renewed interest and, among them, China seems to have the most dynamic approach in order to catch-up with other nations and upgrade relations with African countries. However, the EU is also carrying on its new strategy toward parts of Africa. In these world powers strategies, multiple approaches related to subregions exist, instead of a single regional approach. The objective of this paper is to have a closer look and to analyze how the different regions and major nations of Africa Western Africa, Egypt, Eastern Africa and South Africa) are dealing with their economic and political development path and their interconnection with other areas of the World, with an important focus on China-Africa relations.

Omnivorousness as the bridging of cultural holes: A measurement strategy

Recent research and theory at the intersection of cultural sociology and network analysis have converged around the notion of cultural holes: patterns of cultural choice that position the person as a bridge not between other persons but between cultural worlds. This is an approach that promises to open up new vistas in our conceptualization of the relationship between social position and cultural taste, but that so far lacks operational grounding. In this article, I draw on Breiger’s (1974) formalization of the idea of the duality of persons and groups along with classical formalizations of brokerage for sociometric networks (Burt 1992) to suggest that the “cultural ego network” of a typical survey respondent can be reconstructed from patterns of audience overlap among the cultural items that are chosen by each respondent. This leads to a formalization of the notion of omnivorousness as relatively low levels of clustering in the cultural network: namely, omnivorousness as cultural network efficiency. I show how this metric overcomes the difficulties that have plagued previous attempts to produce ordinal indicators of omnivorousness from simple counts of the number of cultural choices, while providing novel substantive (and sometime counter-intuitive) insights into the relationship between socio-demographic status markers and patterns of cultural choice in the contemporary United States.     

Androgen deficiency in the adult male

Introduction. The purpose of this study was to investigate the association between severity of lower urinary tract symptoms (LUTS), erectile dysfunction (ED) and metabolic syndrome.

Methods. Our study population included a consecutive series of 190 patients with LUTS (International Prostate Symptom Score-IPSS >7) with or without manifestations of the metabolic syndrome. The diagnoses of diabetes mellitus and hypertension were obtained from the patient's medical history. Data on blood pressure, waist measure, body height and weight were collected and body mass index were calculated. Patients were assessed based on the International Index of Erectile Function (IIEF) for ED and IPSS and IPSS-Quality of Life for LUTS. Blood samples were drawn from fasting patients to determine, fasting blood glucose (FBG), triglycerides, HDL-cholesterol and serum total testosterone levels.

Results. In severe LUTS patient group, IIEF erectile function domain scores were significantly lower than moderate LUTS patient group (p < 0.05). Multiple logistic regression analysis confirmed that presence of ED was the most predictor of severe LUTS. The prevalence of metabolic syndrome was higher in patients with severe LUTS (26%vs. 46%, p = 0.009). The severe form of the LUTS was significantly correlated with waist circumference >102 cm (p < 0.05), blood pressure ≥130/85 mmHg (p < 0.05) and FBG >110 mg/dl (p < 0.01).

Conclusion. Obesity, high plasma level of FBG and hypertension constitute risk factors for the development of severe LUTS. Metabolic syndrome may play a key role in the pathogenesis in both ED and LUTS. Presence of ED is the most predictor of severe LUTS.     

Related party transactions and audit fees: the role of the internal audit function

Related party transactions (RPTs) are viewed as genuine transactions that rationally fulfil other economic demands of a company. However, RPTs can also be used to transfer wealth from minority shareholders to controlling shareholders. The existence of such transactions may deteriorate financial reporting quality, increase audit risk, and as a result increase audit fees. This study examines the relationship between RPTs and audit fees in Malaysia, where ownership is often concentrated within a controlling family and corporate governance mechanisms are poor. It also investigates the moderating effect of the internal audit function (IAF) on this relationship. We find that external auditors base their fees on the types of RPTs undertaken. Specifically, our results show that audit fees are higher for firms that undertake RPTs involving the sale and purchase of assets, goods, and services. We also document that external auditors rely on the IAF, and thus their fees are lower for firms that undertake RPTs and that have made a large investment in an IAF. Our study is the first to provide evidence that RPTs in Malaysian firms may be abused as a channel to facilitate tunnelling and that the IAF plays a vital role in controlling such transactions.

Central America and its Perception of 2020 “Regional Integration” Aim

In 2004 Central American countries (Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, and Belize) have strong-willed to go into a process of political, economic, social, cultural, and ecological integration through a Central American Integration System. Some of the challenges that the integration process faces include the strengthening of the decision making process, the cooperative initiatives in economy and trade, particularly due to the sort of overlapping agreement that countries have signed so far. This paper particularly discusses the coordination process and the nature of this atypical regional agreement. Moreover, we face national implementation of regional treaties, participation of civil society, external and cooperation relations and their respective opportunities for trade and commerce.     

Bayesian and fiducial inference for the inverse gaussian distribution via Gibbs sampler

This paper presents a kernel estimation of the distribution of the scale parameter of the inverse Gaussian distribution under type II censoring together with the distribution of the remaining time. Estimation is carried out via the Gibbs sampling algorithm combined with a missing data approach. Estimates and confidence intervals for the parameters of interest are also presented.
