Communication in Statistics-Theory and methods improved GQL estimation method for the generalised BINMA(1) model

In a recent research, the quasi-likelihood estimation methodology was developed to estimate the regression effects in the Generalized BINMA(1) (GBINMA(1)) process. The method provides consistent parameter estimates but, in the intermediate computations, moment estimating equations were used to estimate the serial- and cross-correlation parameters. This procedure may not result optimal parameter estimates, in particular, for the regression effects. This paper provides an alternative simpler GBINMA(1) process based on multivariate thinning properties where the main effects are estimated via a robust generalized quasi-likelihood (GQL) estimation approach. The two techniques are compared through some simulation experiments. A real-life data application is studied.     

Validation of the Australian Midwifery Standards Assessment Tool (AMSAT): A tool to assess midwifery competence

Background

There is no current validated clinical assessment tool to measure the attainment of midwifery student competence in the midwifery practice setting. The lack of a valid assessment tool has led to a proliferation of tools and inconsistency in assessment of, and feedback on student learning.

Queering Canadian Social Work Accreditation standards and procedures: a content analysis

ABSTRACT

This paper reviews and critically analyzes the Canadian Association for Social Work Education—Association Canadienne Pour La Formation En Travail Social’s (CASWE-ACFTS’) Accreditation Standards and Procedures from a Sexual Orientation Gender Identity and Expression (SOGIESC) lens to examine how such are addressed in relevant documents. The CASWE-ACFTS Queer Caucus undertook a lead role in examining ‘diversity’ in the documents as it serves as an umbrella term for SOGIESC and other intersecting positionalities. This paper iterates an initial response in the CASWE-ACFTS Queer Caucus’ ongoing consultation with the CASWE-ACFTS’s Education Policy Committee’s work on Education Policy and Accreditation Standards 2019 (EPAS2019). The content analysis of the documents reveals that SOGIESC issues are not adequately addressed and this has implications for undergraduate and graduate social work curricula in Canada. The authors provide recommendations that address the integration of SOGIESC in CASWE-ACFTS’s Accreditation Standards and Procedures documents.     

Does Remittance Outflow Stimulate or Retard Economic Growth?

This article evaluates the association between remittance outflow (RMO) and economic growth in the Gulf Cooperation Council (GCC) countries. The results of this evaluation indicate that RMO Granger creates gross domestic product (GDP) per capita in three countries, namely, Bahrain, Oman and Saudi Arabia. Similarly, the results for causality from GDP per capita to RMO are significant for four countries, namely, Bahrain, Kuwait, Qatar, and Saudi Arabia. The findings differ from those of the household consumption model, stating that higher RMO will decrease economic activity. GDP per capita is the main determinant of RMO, suggesting that economic growth promises and encourages continuous RMO and vice versa. The adverse impact of RMO can be minimized by encouraging the local population to be productive in the private sector, as local productivity will reduce the huge influx of foreign workers and provide valuable local investment opportunities to lessen the amount being remitted.     

Essential Micro‐foundations for Contemporary Business Operations: Top Management Tangible Competencies,Relationship‐based Business Networks and Environmental Sustainability

Although various studies have emphasized linkages between firm competencies, networks and sustainability at organizational level, the links between top management tangible competencies (TMTCs) (e.g. contemporary relevant quantitative‐focused education such as big data analytics and data‐driven applications linked with the internet of things, relevant experience and analytical business applications), relationship‐based business networks (RBNs) and environmental sustainability have not been well established at micro‐level, and there is a literature gap in terms of investigating these relationships. This study examines these links based on the unique data collected from 175 top management representatives (chief executive officers and managing directors) working in food import and export firms headquartered in the UK and New Zealand. Our results from structural equation modelling indicate that TMTCs are the key determinants for building RBNs, mediating the correlation between TMTCs and environmental sustainability. Directly, the competencies also play a vital role towards environmental practices. The findings further depict that relationship‐oriented firms perform better compared to those which focus less on such networks. Consequently, our findings provide a deeper understanding of the micro‐foundations of environmental sustainability based on TMTCs rooted in the resource‐based view and RBNs entrenched in social network theory. We discuss the theoretical and practical implications of our findings, and we provide suggestions for future research.     

A non‐stationary bivariate INAR(1) process with a simple cross‐dependence: Estimation with some properties

This paper considers modelling of a non‐stationary bivariate integer‐valued autoregressive process of order 1 (BINAR(1)) where the cross‐dependence between the counting series is formed through the relationship of the current series with the previous‐lagged count series observations while the pair of innovations is independent and marginally Poisson. In addition, this paper proposes a generalised quasi‐likelihood (GQL) estimating equation based on the exact specification of the mean score and the auto‐covariance structure. The proposed approach is also compared with other popular techniques such as conditional maximum likelihood (CML), generalised least squares (GLS) and generalised method of moment (GMM) based on simulated data from the proposed BINAR(1). Moreover, the model is applied to weekly series of day and night road accidents arising in some regions of Mauritius and is compared with other existing BINAR(1) models.     

International Remittances and Private Schooling: Evidence from Kerala,India

This study investigates the impact of international remittances on private school enrolment in Kerala. Using data from the 2010 Kerala Migration Survey and employing an instrumental variable (IV‐Probit) approach to address the endogeneity of migration, we found that remittances have a positive and significant effect on private school enrolment. After disaggregating the sample into different heterogeneous groups, we found that remittances have greater effect on boys, children residing in rural areas, and those belonging to socially advantageous groups and from higher wealth quintile. Children from lower wealth quintile and belonging to socially disadvantageous groups are least affected by migration and remittances.     

‘Ghost in the Shell’: Reflections on Fieldwork in Kazakhstan

After independence from the Soviet Union, Kazakhstan proclaimed Kazakhs the title ethnic group, and the Kazakh language the national language. This deprived the Russian-speaking population of its former dominant social position. Being a Russian-speaking citizen of Kazakhstan, the daughter of a half-Korean half-Russian father and a half-Kazakh half-German mother, I did my field work as a presumed ‘native’ anthropologist at Kazakhstan State University with linguistically divided groups of students. The relations between the field and the researcher disclosed different geopolitical realities of knowledge production and challenged the legacy of relativist methodology. I reflect on this experience and examine different conceptualisations of the native positionality in the post-Soviet context. Reflections in this paper raise new questions about nation-building in post-socialist states and about ‘nativeness’ itself, and contribute to the criticism of postmodern theory.     

Exploring the Relationship between Secularity and Marital Behavior

The higher religiosity of women is a longstanding feature of the religious landscape in the Western World. With the recent vibrancy of secular movements, the greater religiosity of women is reflected in a gender imbalance within the secular groups. For instance, more than three quarters of American atheists are male. Given the effects of both religiosity and secularity on worldview and lifestyle, this gender imbalance is likely consequential for marital behavior and outcomes. Using the latest cycle of the Canadian General Social Survey focused on family, this paper examines how marital behavior of individuals without any tie with religion or spirituality compares with others. Secular males are found appreciably more likely to experience marital dissolution, whereas their female counterparts are shown no different from others. This result lends support to the theories that posit religiosity as a complementary marital trait, requiring the mating of the like. The analysis also indicates that union formation behavior of secular females manifests a larger shift away from the traditional conceptions of marriage compared with secular males. Various explanations are explored.     

A new S2 control chart using repetitive sampling

A new S² control chart is presented for monitoring the process variance by utilizing a repetitive sampling scheme. The double control limits called inner and outer control limits are proposed, whose coefficients are determined by considering the average run length (ARL) and the average sample number when the process is in control. The proposed control chart is compared with the existing Shewhart S² control chart in terms of the ARLs. The result shows that the proposed control chart is more efficient than the existing control chart in detecting the process shift.
