Adaptive wavelet estimation of a function from an m-dependent process with possibly unbounded m

The estimation of a multivariate function from a stationary m-dependent process is investigated, with a special focus on the case where m is large or unbounded. We develop an adaptive estimator based on wavelet methods. Under flexible assumptions on the nonparametric model, we prove the good performances of our estimator by determining sharp rates of convergence under two kinds of errors: the pointwise mean squared error and the mean integrated squared error. We illustrate our theoretical result by considering the multivariate density estimation problem, the derivatives density estimation problem, the density estimation problem in a GARCH-type model and the multivariate regression function estimation problem. The performance of proposed estimator has been shown by a numerical study for a simulated and real data sets.     

Governance,religious assurance and Islamic banks: Do Shariah boards effectively serve?

This study examines the quality of governance and religious assurance provided by Shariah boards (SBs) when undertaking the crucial compliance review required in fulfilling the expected ethical and social legitimacy of Islamic banks. To better understand the complex behavioural processes, we explore the governance role of SBs and assess issues related to competence, effectiveness and independence in the light of the newly adopted 2011 Malaysian Shariah Governance Framework (SGF). A series of semi-structured interviews were undertaken with key individuals in two well-established fully-fledged Malaysian Islamic banks. Our findings reveal that the newly implemented SGF has generally brought about some of the benefits hoped for by its regulatory architects. We find the quality of religious assurance to have been enhanced due to the emphasis placed on religious audit giving rise to improved credibility. However, we report the compliance review process to be inadequately undertaken with SBs still excessively reliant on internal officers implying possible independence compromise. We highlight concerns relating to (1) the general level of competency of individual SB members; (2) lack of technical banking and finance knowledge; and (3) SB members generally fulfilling a ceremonial role rather than undertaking vigilant monitoring. Our findings lead us to question the full impact of the new 2011 SGF and query the value and effectiveness of SBs. We make the call for the establishment of external religious auditors to render compliance assurance which could provide the much-needed impetus to improve governance and increase market and stakeholder confidence.     

A new lifetime model with a periodic hazard rate and an application

In this paper, we introduce a new three parameter lifetime distribution for modelling lifetime data. Among its interesting properties, it has the feature of possessing a periodic hazard rate function. Some of its mathematical properties are studied, including moments, moment generating function, mean deviations and order statistics. The estimation of its parameter is investigated using the maximum-likelihood estimation. A real-life data set is considered to illustrate the usefulness and the applicability of the proposed distribution.     

An extended Lindley distribution

In this paper we introduce an extension of the Lindley distribution which offers a more flexible model for lifetime data. Several statistical properties of the distribution are explored, such as the density, (reversed) failure rate, (reversed) mean residual lifetime, moments, order statistics, Bonferroni and Lorenz curves. Estimation using the maximum likelihood and inference of a random sample from the distribution are investigated. A real data application illustrates the performance of the distribution.     

Domestic Harm and Neglect Among Lesbian,Gay, and Bisexual Older Adults

This study examined harm, hurt, and neglect by caregivers as well as self-neglect and physical and mental health status among 113 lesbian, gay, and bisexual (LGB) older adults aged 60–88 years, who attended community-based social and recreation programs or groups in the United States. Reporting on their experiences with caregivers, 22.1% of the participants experienced at least one type of harm, including physical, emotional, verbal, sexual, financial, and neglectful; additionally, 25.7% of the participants reported they knew LGB older adults who experienced at least one type of harm from his or her caregiver. With regard to self-neglect, 62.8% reported experiencing it; those indicating positive psychological health reported fewer experiences with self-neglect.     

A Longitudinal Examination of Work–Family Balance among Working Mothers in the United States: Testing Bioecological Theory

The current study used a bioecological framework to examine three moderated-mediation models testing the mediating effects of positive work-to-family spillover and positive family-to-work spillover in the relationship between a nonstandard work schedule and work–family balance as well as between relationship quality and work-to-family balance. The moderating effects of education, family–friendly workplace policies, and race in the aforementioned models also were tested. Path analyses were used with longitudinal data from four-time periods to test the models. Results showed family-to-work spillover mediated the relationship between relationship quality and work–family balance in two models, whereas the availability of family–friendly policies significantly moderated these relationships. Relationship quality was one of the most consistently significant variables across all models, suggesting its role in helping establish work-family balance is particularly influential regardless of context. Implications and directions for future research are discussed.

     

GIS and development control system for a local authority in Malaysia

The process of development control involves a technique for the systematic compilation of expert quantitative analysis and qualitative assessment of project land use and property development viability, including its effect on the surrounding area, and the presentation of results in a way that enables the importance of the predicted results, and the scope of modifying or mitigating them to be properly evaluated by the relevant decision making body before a planning permission is rendered. Taking the local authorities in Malaysia as an example, this paper will discuss and demonstrate the development of a GIS database and its integration and application for development and building control. The first part of the paper examines the functions of local authorities particularly in the context of development control. In this study, the procedure involved in granting a planning permission as well as enforcement becomes the main focus because it determines the bulk of the system design. The study identifies seven sub-systems namely planning permission, building control, planning enforcement, geospatial database, information kiosk, document processing and presentation sub-systems. The system is developed using a combination of office automation, CAD, GIS, multimedia and other software packages. This paper will focus on the development of the GIS for the purpose of development control. The components of the GIS database include land information, buildings, existing developments, planning information, development plans, utilities, community facilities, transportation, environment and the socio-economy database. The GIS database will be used at every stage of development control, for example, in initial discussions, registration, invitation of objections, the development control process, the consideration by Technical Committee and the consideration by Planning Committee. It is anticipated that the GIS database could be used by many parties involved in the process as a reference point in evaluating a planning submission. Having access to the database will provide flexibility in assessing a proposed development and deciding on the overall urban growth management programme in the most cost-effective manner. The system will also provide transparency and consistency in the development control procedure.     

WANT EXPORT DIVERSIFICATION? EDUCATE THE KIDS FIRST

This paper uses Bayesian model averaging to uncover the true determinants of export diversification among 36 potential factors, and thus 2³⁶ potential models. Using data from 2001 to 2010, our results reveal two strong predictors: Primary school enrollment (99.7% posterior inclusion probability in the true model) raises export diversification, whereas the share of natural resources in gross domestic product (98.6%) lowers diversification levels. The importance of basic education coverage offers policymakers an opening toward diversifying exports, at least in the long run. This result is robust to accounting for the endogeneity of income levels by applying an instrumental variable BMA method. (JEL C11, F1, F34, O1, O2, O11)     

The Moderating Effects of National Age Stereotyping on the Relationships between Job Satisfaction and its Determinants: A Study of Older Workers across 26 Countries

This research explores how national age stereotypes impact older workers' job‐related perceptions by examining probability based samples across 26 countries taken from the European Social Survey. Multilevel data analysis was undertaken. Results show that, at the individual level, both extrinsic rewards and intrinsic rewards directly impact older workers' job satisfaction. At the country level, significant variations are found in the relationships between job satisfaction and related rewards for older workers across the 26 countries. Society's stereotypical views towards older people explained some of these cross‐country variations. This study contributes to extant literature by explicating the process by which society's age stereotypes and the meta‐stereotypes held by older workers affect how these workers make sense and take meaning out of their job‐related circumstances leading to enhanced or diminished job satisfaction. Implications highlight the need for management to be vigilant in identifying and dealing with age stereotypes in the workplace. Furthermore, managers need to be more aware of the potential harmful consequences arising from negative meta‐stereotypes and should implement strategies to tackle workplace stereotypes that would lead to negative meta‐stereotypes held by older workers.     

A new discrete distribution

A new one-parameter discrete distribution is introduced. Its mathematical properties and estimation procedures are derived. Four real data sets are used to show that the new model performs at least as well as the traditional one-parameter discrete models and other newly proposed two-parameter discrete models.
