Abstract

This chapter revisits the Hausman (1978) test for panel data. It emphasizes that it is a general specification test and that rejection of the null signals misspecification and is not an endorsement of the fixed effects estimator as is done in practice. Non-rejection of the null provides support for the random effects estimator which is efficient under the null. The chapter offers practical tips on what to do in case the null is rejected including checking for endogeneity of the regressors, misspecified dynamics, and applying a nonparametric Hausman test, see Amini, Delgado, Henderson, and Parmeter (2012, chapter 16). Alternatively, for the fixed effects die hard, the chapter suggests testing the fixed effects restrictions before adopting this estimator. The chapter also recommends a pretest estimator that is based on an additional Hausman test based on the difference between the Hausman and Taylor estimator and the fixed effects estimator.

This study aims to assess the impact of participation in self-help group (SHG) on the psychological empowerment of rural tribal women.

Abstract

Purpose

This study aims to assess the impact of participation in self-help group (SHG) on the psychological empowerment of rural tribal women.

Design/methodology/approach

Primary data was collected using multistage random sampling from the rural women of Jharkhand, India. The propensity score matching method was adopted using the psmatch2 command in STATA.

Findings

The results show a significant positive change in women’s self-esteem, self-confidence, self-efficacy, autonomy, knowledge and skills, reduction in agony and quality of life after participation in SHG. This reveals that participation in SHG has a significant positive impact on the psychological empowerment of rural tribal women.

Originality/value

Despite the numerous studies on rural women’s empowerment, there is little evidence of literature focusing on the impact of participation in SHG on psychological empowerment, specifically in the tribal context. This study primarily focuses on women belonging to the scheduled tribe category of Jharkhand, one of the poorest states of India.

Abstract

Purpose

Pakistan ranks third globally in terms of newborn deaths occuring within the first 24 hours of life. With a neonatal mortality rate of 42.0%, it carries the highest burden compared to neighboring countries such as Bangladesh (17%), India (22.7%) and Afghanistan (37%). While there has been a decline in neonatal mortality rates in Pakistan, the pace of this decline is slower than that of other countries in the region. Hence, it is crucial to conduct a comprehensive examination of the risk factors contributing to neonatal mortality in Pakistan over an extended period. This study aims to analyze the trends and determinants of neonatal mortality in Pakistan over three decades, providing valuable insights into this persistent issue.

Design/methodology/approach

The study focused on neonatal mortality as the response variable, which is defined as the death of a live-born child within 28 days of birth. Neonates who passed away during this period were categorized as “cases,” while those who survived beyond a specific timeframe were referred to as “noncases.” To conduct a pooled analysis of neonatal mortality, birth records of 39,976 children born in the five years preceding the survey were extracted from four waves (1990–2018) of the Pakistan Demographic and Household Survey. The relationship between risk factors and the response variable was examined using the Cox Proportional Hazard Model. Neonatal mortality rates were calculated through the direct method using the “syncmrates” package in Stata 15.

Findings

During the extended period in Pakistan, several critical protective factors against neonatal mortality were identified, including a large family size, improved toilet facilities, middle-aged and educated mothers, female children, singleton live births, large size at birth and longer birth intervals. These factors were found to reduce the risk of neonatal mortality significantly.

Originality/value

This study makes the first attempt to analyze the trends and patterns of potential risk factors associated with neonatal mortality in Pakistan. By examining a large dataset spanning several years, the study provides valuable insights into the factors influencing neonatal mortality.

Abstract

Purpose

The provision of facilities management (FM) services, facilitated by a well-suited sourcing strategy, significantly influences the optimization of dwelling unit performance, augmentation of occupants’ living experiences and the establishment of a secure and comfortable environment. Consequently, this study aims to examine the sourcing approach used for delivering FM services in social housing within Nigeria’s semi-arid climate and to assess the effectiveness of the chosen sourcing approach in the provision of FM services.

Design/methodology/approach

Data collection involved one-on-one interviews conducted with five principal/senior staff members of the Borno State Housing Corporation in Maiduguri, Northern Nigeria. For data analysis, the NVivo R1 software package and Stata 13.0 were used. Thematic analysis was applied to the data, and the findings were presented through narrations and direct quotes from participants. Logistic regression analysis was subsequently used to assess the effectiveness of the adopted in-house approach in providing FM services in the context of social housing.

Findings

Administrators of social housing in the semi-arid climate of Nigeria exclusively adopted an in-house sourcing approach for providing FM services. Nevertheless, the in-house approach was conclusively determined to be ineffective in delivering FM services within the specific context of social housing in the semi-arid climate of Nigeria.

Originality/value

This investigation centred on examining the sourcing strategy used by social housing administrators for delivering FM services in social housing within a semi-arid climate of Nigeria. Additionally, the study delved into evaluating the efficacy of the chosen sourcing approach in the actual provision of FM services.

Abstract

In the new economy, governed by technological progress and informational abundance, e-government service represents one of the drivers of the digital economy and society. The government and its institutions have the role of stimulating, leading, and controlling the process of transition to the digital society, which is a key component for the future prosperity and resilience of the European Union (EU). With focus on a better functioning of society by improving the citizens' access and use of e-government services, in this work we aim to identify the factors that influence the online interaction of individuals with public authorities in the EU member states. We used panel data for the EU member states in the period 2013–2021 to investigate the determinants of individuals' interaction with public authorities through institutional websites, using clustering regression with fixed effects, which allows both the clustering of the states and obtaining different slope parameters for each cluster. The results indicated the grouping of the EU states in an optimal number of two clusters, and the fixed effects regression clustering pointed out different coefficients for the two clusters, indicating distinct patterns. The main factors that influence the online interaction of citizens with public authorities are related to internet use, education, and government effectiveness, but the impact is different for the two clusters, depending on the specifics of the component countries.

Abstract

Education researchers have been urged to utilize causal inference methods to estimate the policy effect more rigorously. While randomized controlled trials (RCTs) are the gold standard for assessing causality, RCTs are infeasible in some educational settings, particularly when ethical concerns or high cost are involved. Quasi-experimental research designs are the best alternative approach to study educational topics not amenable to RCTs, as they mimic experimental conditions and use statistical techniques to reduce bias from variables omitted in the empirical models. In this chapter, we introduce and discuss the core concepts, applicability, and limitations of three quasi-experimental methods in higher education research (i.e., difference-in-differences, instrumental variables, and regression discontinuity). By introducing each of these techniques, we aim to expand the higher education researcher's toolbox and encourage the use of these quasi-experimental methods to evaluate educational interventions.

Abstract

Purpose

Generative pretrained transformers (GPTs), soaring to one million users at lightning speed, outpaced social media giants (15 times faster) (Buchholz, 2023). Despite this, scant research explored GPT’s impact on the digital entrepreneurial intentions (EIs) of students and tech-savvy generations. This study aims to pioneer a fusion of the technology acceptance model (TAM) and the theory of planned behavior (TPB), bridging the gap in research.

Design/methodology/approach

In this bold quantitative quest, business administration students became fearless participants, engaging in a survey of profound significance. Guided by the mighty powers of G*Power and Stata’s structural equation modeling builder, the intricate relationships within a robust sample of (n = 400) were unraveled.

Findings

The mediating power of GPT usefulness and GPT ease of use part of the TAM emerges, paving the way for a future brimming with digital entrepreneurship (DE) boundless possibilities. Predictably, the study found that TPB constructs also affect the EI of students.

Originality/value

This groundbreaking study brings together the powerful combination of TAM and TPB, while pioneering the exploration of GPT models’ mediating role. Its findings offer invaluable contributions to the field of DE and policymakers.

Abstract

Purpose

This paper aims to examine the relationship between environmental, social and governance (ESG) performance and systemic risk sensitivity of Chinese listed companies. From the consumer loyalty and investor structure perspectives, the relationship between ESG performance and systemic risk sensitivity is analyzed.

Design/methodology/approach

Since Morgan Stanley Capital International (MSCI) ESG officially began to analyze and track China A-shares from 2018, 275 listed companies in the SynTao Green ESG testing list for 2015–2021 are selected as the initial model. To measure the systematic risk sensitivity, this study uses the beta coefficient, from capital asset pricing model (CPAM), employing statistics and data (STATA) software.

Findings

The study reveals that high ESG rating companies have high corresponding consumer loyalty and healthy trading structure of institutional investors, thereby the systemic risk sensitivity is lower. This paper reveals that companies with high ESG rating are significantly less sensitive to systemic risk than those with low ESG rating. At the same time, ESG has a weaker impact on the systemic risk of high-cap companies than low-cap companies.

Practical implications

The study helps the companies understand the influence of market value on the relationship between ESG performance and systemic risk sensitivity. Moreover, this paper explains explicitly why ESG performance insulates a firm’s stock from market downturns with the lens of consumer loyalty theory and investor structure theory.

Originality/value

The paper provides new insights on the company’s ESG performance that significantly affects the company’s systemic risk sensitivity.

Abstract

Purpose

To solve the obstacle detection problem in robot autonomous obstacle negotiation, this paper aims to propose an obstacle detection system based on elevation maps for three types of obstacles: positive obstacles, negative obstacles and trench obstacles.

Design/methodology/approach

The system framework includes mapping, ground segmentation, obstacle clustering and obstacle recognition. The positive obstacle detection is realized by calculating its minimum rectangle bounding boxes, which includes convex hull calculation, minimum area rectangle calculation and bounding box generation. The detection of negative obstacles and trench obstacles is implemented on the basis of information absence in the map, including obstacles discovery method and type confirmation method.

Findings

The obstacle detection system has been thoroughly tested in various environments. In the outdoor experiment, with an average speed of 22.2 ms, the system successfully detected obstacles with a 95% success rate, indicating the effectiveness of the detection algorithm. Moreover, the system’s error range for obstacle detection falls between 4% and 6.6%, meeting the necessary requirements for obstacle negotiation in the next stage.

Originality/value

This paper studies how to solve the obstacle detection problem when the robot obstacle negotiation.

Abstract

Purpose

Drug use in prisons remains a public health concern because it is often the place of drug initiation. The purpose of this study was to analyze the drug use in prison in Burkina Faso.

Design/methodology/approach

We conducted cross-sectional study in the prison of Ouagadougou. The adult prisoners (male and female) incarcerated for more than one month at the largest prison of Burkina Faso were included in the study. Participants were selected using a systematic random sampling. Data were collected from October 28 to November 26, 2018. The face-to-face interviews were conducted in the prison grounds. Logistic multivariate regression was used to identify factors associated with in prison drug use. All analysis was done using Stata.

Findings

A total of 379 prisoners were included in this study. Approximately one-third inmates (32.71%; n = 124) experienced illicit drug in lifetime. Nearly one-third (28.76%; n = 109) of the prisoners were drug users before incarceration and 11.87% (n = 45) used drug inside the prison, of which 33.33% (n = 15) initiated drug use in the prison. Cannabis was the first drug used by the prisoners (71.11%) followed by tramadol (62.22%), diazepam (13.33%) and cocaine (2.22%). Four prisoners (3.63%) had reported Heroin use before incarceration. Cannabis was mainly smoked. Tramadol, diazepam and amphetamines were swallowed or mixed with food. Cocaine is smoked and snorted. Case of injection of cocaine and heroin was reported before incarceration. Main factors independently associated with drug use in prison is drug use before prison and young age of inmates. Indeed, inmates who had reported drug use before prison had 4.01 time {adjusted odd ratio (AOR: 4.01 [95% CI: 1.91–8.41])} higher odds to use drug in prison.

Research limitations/implications

To conduct the interviews in the prison grounds could be a limitation due to social desirability bias. Indeed, the prisoners may understate drug use in prison for the fear of likely additional sentence. Availability of biological tests for drug markers might help addressed this bias. Nevertheless, the findings of this study should help to plan effective drug use prevention and care programs for prisoners.

Practical implications

The actions must include the implementation of a medical and psychological care in continuum of healthcare system in Burkina Faso. This system should include screening at entry and adequate health and psychological care in prison for drug users for an effective control of drugs use in prison.

Social implications

Most of these drug users in prison have a low level of education and are unemployed. Education activities and training on occupational activities to prepare drug users for a successful social reintegration less dependent on drugs is essential. This study can be a basis to explore more possibilities and find out what is available to help those with substance use disorder, manage these cases in prison and prevent relapse on release.

Originality/value

To the best of the authors’ knowledge, this study is the first study on drug use in prison in Burkina Faso. It indicates that the repressive strategy against drug use seems ineffective because former users continue their consumption inside and also new users are initiated to use drugs in prison.
