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.

Using the examples of Grenadian-born Jean Augustine, the first Black Member of Parliament in Canada, and Barbados' Prime Minister Mia Mottley, the piece argues that the ethos of the Emigrant Ambassador—the collective empowerment of Black feminism, liberation, and radicalism—ushered in a new era for change abroad and in Canada, as transnational and international change was driven by Black women from the West Indies.

The author used historical research and social science theoretical frameworks to formulate conclusions, lessons learnt and steps forward for current equity, diversity and inclusion (EDI) practitioners.

Black women born in the West Indies in the mid-twentieth century were the catalysts for social justice movements in the 2010 and 2020s. Many methods used for social change in the twentieth century are applicable in the 2020s and beyond.

Research is focused on Canadian and West Indian relations but will have implications for those across the British Commonwealth.

Practitioners and students of EDI will have a new tool on how to approach and confront anti-Black racism, particularly after May 25, 2020.

This article provides opportunities to support the dwindling efforts of anti-racism to support the lives of Black people across the Black Atlantic.

This research aimed to fill several gaps in the tipping literature which has overlooked the server's perspective in identifying and understanding variables that influence a tip amount and therefore where they concentrate their efforts during the service encounter. Furthermore, the extant literature has theorized how or why certain variables influence the tip amount, but these studies fail to capture insight from server's which would supplement the theory and provide a more in-depth understanding of the mechanisms at play.

This study adopts a grounded theory approach using semi-structured one-on-one interviews with tipped restaurant employees who were identified and selected using snowball sampling. Content analysis is employed to code and categorize the data.

The content analysis revealed five categories where servers focus their time and effort to earn tips: service quality, connection, personal factors, expertise and food quality. The server's personality was identified as a variable the tipping literature has largely ignored as a determinant of the tip amount. Server's shift their style of service for groups of eight or more people, and for regular customers, who must dine in the restaurant at least once per week. Lastly, despite the many drawbacks associated with working for tips, servers would not want to replace it with any other method of compensation.

This is the first qualitative study focused on understanding the server's role in the service exchange relationship since McCarty et al. (1990) study. The results provide new insights on the often-studied variables from the tipping literature.

The authors propose to estimate a varying coefficient panel data model with different smoothing variables and fixed effects using a two-step approach. The pilot step estimates the varying coefficients by a series method. We then use the pilot estimates to perform a one-step backfitting through local linear kernel smoothing, which is shown to be oracle efficient in the sense of being asymptotically equivalent to the estimate knowing the other components of the varying coefficients. In both steps, the authors remove the fixed effects through properly constructed weights. The authors obtain the asymptotic properties of both the pilot and efficient estimators. The Monte Carlo simulations show that the proposed estimator performs well. The authors illustrate their applicability by estimating a varying coefficient production frontier using a panel data, without assuming distributions of the efficiency and error terms.

A semiparametric stochastic frontier model is proposed for panel data, incorporating several flexible features. First, a constant elasticity of substitution (CES) production frontier is considered without log-transformation to prevent induced non-negligible estimation bias. Second, the model flexibility is improved via semiparameterization, where the technology is an unknown function of a set of environment variables. The technology function accounts for latent heterogeneity across individual units, which can be freely correlated with inputs, environment variables, and/or inefficiency determinants. Furthermore, the technology function incorporates a single-index structure to circumvent the curse of dimensionality. Third, distributional assumptions are eschewed on both stochastic noise and inefficiency for model identification. Instead, only the conditional mean of the inefficiency is assumed, which depends on related determinants with a wide range of choice, via a positive parametric function. As a result, technical efficiency is constructed without relying on an assumed distribution on composite error. The model provides flexible structures on both the production frontier and inefficiency, thereby alleviating the risk of model misspecification in production and efficiency analysis. The estimator involves a series based nonlinear least squares estimation for the unknown parameters and a kernel based local estimation for the technology function. Promising finite-sample performance is demonstrated through simulations, and the model is applied to investigate productive efficiency among OECD countries from 1970–2019.

This study explores the effects of parents' attending status and alcohol consumption (scenario based) on their feelings of happiness, relaxation, family cohesion and family satisfaction.

This study uses a 2 (attending status: with a child or without a child) X 3 (alcohol consumption: water, a cup of beer or four cups of beers) between-subjects experimental design on an art festival and employs relational cohesion theory while spillover theory.

The results reveal (1) significant differences between parents' attending status on happiness and relaxation; (2) significant differences between alcohol consumption on happiness, family cohesion, and family satisfaction and (3) happiness significantly mediates the effect of parents' alcohol consumption on family cohesion and family satisfaction.

Attending art festivals provides families with a chance to consolidate family relationships. Art festival planners could promote the festival through enhancing participants' family cohesion and satisfaction through potential family leisure activities.

Events are an emerging topic in the hospitality and tourism discipline in recent years. Social impacts, especially family-related outcomes, on art festivals are barely examined. Additionally, while alcohol consumption is common in festivals, the influence of alcohol consumption on the attendees' emotions and behaviors is under-researched.

This study, which is a cross-sectional survey, aims to investigate health-care academics, clinicians and students’ perspectives of health-care simulation-based learning (SBL) and extended reality (XR) haptics use within health-care education. Participants’ views regarding the application, barriers and facilitators of SBL and XR haptics were explored.

The authors conducted an online international cross-sectional survey of 178 participants.

The survey found high health-care SBL use (n = 97, 55.1%) but low awareness (n = 48, 27.3%) or prior use of XR haptics (n = 14, 7.9%). Participants expressed interest in XR haptic technology emphasising its potential in SBL, particularly for understanding anatomy and physiology, enhancing clinical reasoning and consultation and practical skills.

Whilst there was interest in XR haptics, few participants described previous experience of using this technology in SBL. A large percentage of the participants were UK-based. Most participants were from a nurse or physiotherapy professional background.

XR haptics is a developing technology for SBL in health-care education. Whilst there was clear interest from survey participants, further research is now required to develop and evaluate the feasibility of using this technology in health-care education.

Health-care students, educators and clinicians views on XR haptics have not previously been explored in the development and application of this technology. The findings of this survey will inform the development of XR learning scenarios that will be evaluated for feasibility in health-care SBL.

Four reputed leaders for the coming years in the field of special education for individuals with emotional and behavioral disorders (EBD) each with a slightly different perspective on the field were asked to respond independently to a prompt asking what does special education mean for students with EBD and what is being done and how do we maintain tradition? The contributors' responses to the prompt are presented and then summarized across the essays. A remarkable consistency emerges across the independent essays. In addition to the tradition of providing a free and appropriate education in the least restrictive environment, the contributors identify needs to support teachers serving this population. Needs in teacher training and the expertise required to meet the needs of individuals with EBD are outlined as well as potential contributions of technology to carry out specific tasks. We conclude with a call for increased advocacy for use of the knowledge that we currently possess and that which will soon be discovered to support students with EBD as well as their teachers. We also note that the contributors' names are listed alphabetically to acknowledge the equality of each person to the final product.

Scarcity of resources, ecological imbalance, global warming, rising energy prices and the ever-changing need for variety have attracted the government and manufacturers for sustainable development of the industries. The integrated sustainable-green-lean-six sigma-agile manufacturing system (ISGLSAMS) provides a solid platform for meeting both the customers’ variety needs and business sustainability requirements. Many organizations opted for ISGLSAMS, but still due to various barriers organizations are not able to fully implement ISGLSAMS. The purpose of this paper is to identify the barriers to the ISGLSAMS, so that a more sustainable industrial manufacturing system and industrial symbiosis can be developed.

A literature review, from the Web of Science and Google Scholar database, has been carried out to identify the various barriers to the implementation of ISGLSAMS in the entire value chain. A total of 168 research papers have been reviewed for identifying the ISGLSAMS barriers.

This paper elaborates the concept of the ISGLSAMS, its attributes and various barriers and contributes to a better understanding and successful implementation of ISGLSAMS to meet business’ sustainability and market performance goals in the entire value chain. The paper also projects the future research framework and directions for the ISGLSAMS, integrated sustainable-green-lean-six sigma-agile (ISGLSA) product and ISGLSA supply and value chain.

The study contributes to a better understanding of ISGLSAMS’ barriers. The government, stakeholders and policymakers may plan the policy, road map and strategies to overcome the ISGLSAMS’ barriers. In-depth knowledge of subclauses of ISGLSAMS’ barriers will help the practitioners to overcome the ISGLSAMS’ barriers strategically. By overcoming the ISGLSAMS barriers, a more sustainable 7 Rs based market focused manufacturing system can be designed. This will also increase the opportunities to enhance the industrial ecology, industrial symbiosis and better recovery of the product, process and supply chain residual value. This will reduce the waste to the ecosystem.

This work has been carried out in search of a more sustainable manufacturing system, i.e. ISGLSAMS (which is 7 Rs based, i.e. 6 Rs of sustainability with 7th R, reconfiguration) to meet the customer variety needs along with sustainability in the ever-changing customer market. This study adds value to the practitioners to identify and prioritize the ISGLSAMS’ industry-specific barriers and design the solution for the more sustainable development of (1) industries, (2) the industrial symbiosis system and (3) the ISGLSA product, process, system and supply value chain with minimum resource consumption and environmental impact. The research also contributes to the (a) ISGLSAMS (b) ISGLSA supply chain (c) reconfigurable, sustainable and modular products and (d) redesign, recovery and refurbishing of the product to increase the product life cycle.
