A MACROECONOMIC ANALYSIS OF ENERGY SUBSIDIES IN A SMALL OPEN ECONOMY

We construct a dynamic model of a small open economy to analyze the effects of large energy subsidies. The model includes domestic energy production and consumption, trade in energy at world market prices, as well as private and public sector production. The model is calibrated to Egypt and used to study reforms such as reductions in energy subsidies with corresponding reductions in various tax instruments or increases in infrastructure investment. We calculate the new steady states, transition paths to the new steady state, and the size of the associated welfare losses or gains. Our main results for a 15% cut in energy subsidies are: (1) Steady state gross domestic product drops in most of our experiments as less energy is used in production. (2) Steady state consumption rises in most of our experiments. (3) Welfare can rise by as much as 0.6% in consumption equivalent terms. (4) The largest gains in terms of output and of welfare can be obtained when savings from energy subsidy cuts are used to fund additional infrastructure investment.

Theoretical properties of tests for spatial clustering of count data

Testing for spatial clustering of count data is an important problem in spatial data analysis. Several procedures have been proposed to this end but despite their extensive use, studies of their fundamental theoretical properties are almost non‐existent. The authors suggest two conditions that any reasonable test for spatial clustering should satisfy. The latter are based on the notion that the null hypothesis should be rejected almost surely as the amount of spatial clustering tends to infinity. The authors show that the chisquared test and the Potthoff—Whittinghill V have both properties but that other classical tests do not.     

Robust Bayesian estimation of a two-parameter exponential distribution under generalized Type-I progressive hybrid censoring

A generalized Type-I progressive hybrid censoring scheme was proposed recently to overcome the limitations of the progressive hybrid censoring scheme. In this article, we provide a robust Bayesian method to estimate the unknown parameters of the two-parameter exponential distribution of a generalized Type-I progressive hybrid censored sample. For each parameter, we derive the marginal posterior density functions and the corresponding Bayesian estimators under the squared error loss function. To assess the proposed method, Monte Carlo simulations are performed using a real dataset.

Bayesian inference on extreme value distribution using upper record values

In this paper we address estimation and prediction problems for extreme value distributions under the assumption that the only available data are the record values. We provide some properties and pivotal quantities, and derive unbiased estimators for the location and rate parameters based on these properties and pivotal quantities. In addition, we discuss mean-squared errors of the proposed estimators and exact confidence intervals for the rate parameter. In Bayesian inference, we develop objective Bayesian analysis by deriving non informative priors such as the Jeffrey, reference, and probability matching priors for the location and rate parameters. We examine the validity of the proposed methods through Monte Carlo simulations for various record values of size and present a real data set for illustration purposes.     

When Do People Speak Out? Integrating the Spiral of Silence and the Situational Theory of Problem Solving

Combining spiral of silence theory with the situational theory of problem solving, this study explores the extent to which publics differ in their willingness to express their opinions in hostile social situations. Based on analysis of a survey among 369 college students about their willingness to express opinions on 2 controversial topics (gun possession and climate change), 3 key findings emerge: (a) Fear of isolation suppresses people's willingness to express their opinions in public; (b) active publics are more likely than other types of publics to express their opinions; and (c) there is no interaction effect between fear of isolation and types of publics. In addition to several theoretical contributions, the findings provide public relations practitioners with a model for predicting which types of publics would be more or less likely to express their opinion.     

Prevalence of Sexual Dysfunction and Associated Risk Factors in Middle-Aged and Elderly Korean Men in Primary Care

Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.

Reconstruction of social work education in China through transformative partnership: Case study of the 30 years’ partnership between The Hong Kong Polytechnic University and Peking University

ABSTRACT

Social work education, first introduced to the Chinese mainland in the 1920s, was eliminated from all universities in the early 1950s, but was restored to higher education institutions to respond to the growing demand for social workers in the end of 1980s to resolve escalating social problems triggered by the open-door economic policy. In this paper, the authors will present the concept of transformative partnership and discuss the evolvement of the partnership relationship between The Hong Kong Polytechnic University and Peking University during the past thirty years in fostering the reconstruction of social work education in Mainland China from 1988 to 2018 and beyond. The authors will illustrate the gradual deepening of our partnership from one which was transactional to one that is transformative in nature. The authors believe that our partnership has not only transformed the traditional paradigm of professional education in China but has also transformed all the key stakeholders involved, particularly the educators, students and service-users through the partnership process.
