Rare and clustered population estimation using the adaptive cluster sampling with some robust measures

The use of robust measures helps to increase the precision of the estimators, especially for the estimation of extremely skewed distributions. In this article, a generalized ratio estimator is proposed by using some robust measures with single auxiliary variable under the adaptive cluster sampling (ACS) design. We have incorporated tri-mean (TM), mid-range (MR) and Hodges-Lehman (HL) of the auxiliary variable as robust measures together with some conventional measures. The expressions of bias and mean square error (MSE) of the proposed generalized ratio estimator are derived. Two types of numerical study have been conducted using artificial clustered population and real data application to examine the performance of the proposed estimator over the usual mean per unit estimator under simple random sampling (SRS). Related results of the simulation study show that the proposed estimators provide better estimation results on both real and artificial population over the competing estimators.     

My life is a mess: self-deprecating relatability and collective identities in the memification of student issues

ABSTRACT

In this paper, we investigate memes about student issues. We consider the memes as expressions of a new networked student public that contain discourses that may fall outside the mainstream discourse on higher education. The paper is based on content analysis of 179 posts in the public Facebook Group ‘Student Problem Memes’, combined with a nine-month media watch and a discussion workshop with 15 students. Through self-deprecating humour, students create an inverse attention economy of competitive one-downmanship, where the goal is to display humorous failure instead of perfect appearance. Our analysis shows that students use humour to express, share, and commiserate over daily struggles, but also that the problems related to work/study balance and mental health, are experienced as a persistent feature of student living. We also analyse limitations of meme-based publics, emphasizing processes of inclusion and exclusion through specific vernaculars of visual and discursive humour where issues related to gender, race, orientation, class, and ability are sidelined in favour of relatable humour.     

Expenditure Differences of University Degree Holders Across Occupational Sectors in Malaysia

This study was motivated by the key role university degree holders play in Malaysia's vision for the future and by concerns expressed about the drift of university degree holders from one sector to another. A questionnaire was mailed to a sample of 400 Malaysian families that had at least one member who held a university degree. The objective was to elicit details of the household economic situation of respondents, with special reference to the differences in expenditure patterns between families whose degree holder worked in higher education, government, or the private sector.Results of tobit analysis of expenditures show that there are some differences between the sectors regarding expenditure patterns, but the differences are not as great as expected. Nevertheless, university-educated persons in the private sector seem to have somewhat different expenditure patterns than their counterparts in other sectors.     

A FAMILY THERAPIST RATING SCALE*

This article reports the development of a scale for evaluating family therapist skills. The scale includes ten items within each of five skill categories. All items were found to discriminate significantly between videotaped segments of effective and ineffective family therapist skills. Also all skill categories discriminated significantly between experienced and inexperienced family therapists. The interrater reliability and internal consistency of the categories were also judged to be acceptable. Suggestions are presented for uses of the scale in therapist training research.     

Fitting probability distributions to economic growth: a maximum likelihood approach

The growth rate of the gross domestic product (GDP) usually carries heteroscedasticity, asymmetry and fat-tails. In this study three important and significantly heteroscedastic GDP series are examined. A Normal, normal-mixture, normal-asymmetric Laplace distribution and a Student's t-Asymmetric Laplace (TAL) distribution mixture are considered for distributional fit comparison of GDP growth series after removing heteroscedasticity. The parameters of the distributions have been estimated using maximum likelihood method. Based on the results of different accuracy measures, goodness-of-fit tests and plots, we find out that in the case of asymmetric, heteroscedastic and highly leptokurtic data the TAL-distribution fits better than the alternatives. In the case of asymmetric, heteroscedastic but less leptokurtic data the NM fit is superior. Furthermore, a simulation study has been carried out to obtain standard errors for the estimated parameters. The results of this study might be used in e.g. density forecasting of GDP growth series or to compare different economies.     

Stringency-based ranking of normality tests

Many parametric statistical inferential procedures in finite samples depend crucially on the underlying normal distribution assumption. Dozens of normality tests are available in the literature to test the hypothesis of normality. Availability of such a large number of normality tests has generated a large number of simulation studies to find a best test but no one arrived at a definite answer as all depends critically on the alternative distributions which cannot be specified. A new framework, based on stringency concept, is devised to evaluate the performance of the existing normality tests. Mixture of t-distributions is used to generate the alternative space. The LR-tests, based on Neyman–Pearson Lemma, have been computed to construct a power envelope for calculating the stringencies of the selected normality tests. While evaluating the stringencies, Anderson–Darling (AD) statistic turns out to be the best normality test.     

Civil society organizations and participatory local governance in Pakistan: An exploratory study

This paper analyses the extent to which the civil society organizations (CSOs) have influenced the decision‐making of the local government toward the needs and priorities of citizens. In development discourse, civil society organizations hold a significant importance as they are deemed to provide holistic and new ways to ensure participatory local governance. Therefore, their role against the backdrop of their involvement in mobilizing citizens’ involvement and influencing decision‐making in Pakistan calls for further research. This paper aims to fill this gap. Using qualitative research methods, the current paper appraises the role of CSOs in mobilizing public involvement in the decision‐making process of local government institutions of Punjab, Pakistan. The paper finds that the effectiveness of CSOs is very low due to various institutional and political constraints. Motivations for CSOs seeking citizen involvement have been instrumental in nature rather than motivated by participatory principles.     

Ignoring Leaders who Break Promises or Following God: How Depersonalization and Religious Faith Inform Employees’ Timely Work Efforts

This study investigates the relationship between employees’ perceptions of psychological contract breaches and their failure to meet work-related deadlines, with a particular focus on the mediating role of the depersonalization they assign to organizational authorities and the moderating role of their religious faith. Results based on multisource data, collected among employees and their supervisors in Pakistani organizations, show that an important factor that underpins the connection between beliefs about broken organizational promises and a diminished propensity to finish work on time is that employees depersonalize organizational leaders. This mediating effect is mitigated by employees’ religious faith. For organizations, this study thus identifies a key mechanism – exhibiting indifference to the people in charge – by which employees’ frustrations about resource-depleting contract breaches may inadvertently escalate into ineffective time management, and it identifies some workers among whom this counterproductive dynamic is less likely, namely, employees who can draw from their religious faith.
