Due to the coronavirus 2019 (COVID-19) pandemic, primary and secondary schools worldwide are deploying online teaching/learning practices, fostering and thus innovation practices. The purpose of this study is to determine the degree to which practices reflecting educational innovation are implemented in the Greek public primary and secondary schools operating under conditions characterized by the COVID-19 pandemic. Determining the relationship among these educational innovation practices is also an aim of the present study.

A research study was conducted in the Greek public primary and secondary schools. 522 teachers fully completed a structured questionnaire. Descriptive statistics, exploratory factor analysis and structural equation modeling were applied to analyze the data.

The findings reveal that administration-related innovation practices, teaching-related innovation practices and online teaching/learning practices are implemented to some extent in primary and secondary schools in Greece, but there is still scope for continued development. The online teaching/learning practices set the foundations for further developing a culture of fully adopting other educational innovation practices in these schools to improve education.

Limited research concerning educational innovation practices has focused on primary and secondary schools. The need for more studies on teaching and learning innovations that have resulted from the COVID-19 crisis is highlighted by the literature. The results of this study support the fact that online teaching/learning implemented in primary and secondary schools is positively associated with administration-related and teaching-related innovation practices, concluding that this forced change in the educational process can act as a catalyst for more changes and innovative actions.

This paper aims to develop a model that reflects the current transformer (CT) core materials nonlinearity. The model enables simulation and analysis of the CT excitation current that includes the inductive magnetizing current and the resistive excitation current.

A nonlinear CT model is established with the magnetizing current as the solution variable. This model presents the form of a nonlinear differential equation and can be solved discretely using the Runge–Kutta method.

By simulating variations in the excitation current for different primary currents, loads and core materials, the results demonstrate that enhancing the permeability of the B–H curve leads to a more significant improvement in the CT ratio error at low primary currents.

The proposed model has three obvious advantages over the previous models with the secondary current as the solution variable: (1) The differential equation is simpler and easier to solve. Previous models contain the time differential terms of the secondary current and excitation flux or the integral term of the flux, making the iterative solution complicated. The proposed model only contains the time differential of the magnetizing current. (2) The accuracy of the excitation current obtained by the proposed model is higher. Previous models calculate the excitation current by subtracting the secondary current from the converted primary current. Because these two currents are much greater than the excitation current, the error of calculating the small excitation current by subtracting two large numbers is greatly enlarged. (3) The proposed model can calculate the distorted waveform of the excitation current and error for any form of time-domain primary current, while previous models can only obtain the effective value.

The main purposes of this research are: first of all, to re-classify the types of corporate social responsibility (CSR) into primary stakeholder-oriented CSR and secondary stakeholder-oriented CSR from the perspective of stakeholders and, second, to investigate empirically how and which types of CSR can better impact employees' job satisfaction and happiness management.

An online self-administered questionnaire was adopted to test the conceptual model. Questionnaires were sent to Chinese employees and restrict the data to those whose companies had experience implementing CSR. The study employed the partial least squares structural equation modeling (PLS-SEM) technique for data analysis using SmartPLS 4.0 software.

For factors of happiness management, both primary stakeholder-oriented CSR and secondary stakeholder-oriented CSR had significant and positive effects on happiness management. In addition, both primary and secondary stakeholder-oriented CSR positively and significantly affected job satisfaction, with primary stakeholder-oriented CSR way larger than secondary stakeholder-oriented CSR. Job satisfaction, in turn, was positively and significantly associated with happiness management. The results showed that the control variables of gender and education background had significant effects on happiness management.

First, the results provide useful empirical evidence in support of the feasibility that firms could develop competitive and sustainable development strategies by paying more attention to CSR practices. In terms of the primary stakeholder-oriented CSR, managers are recommended to put employees' benefits as a priority and invest in the to offer a healthy and safe working environment or employee support programs. In terms of the secondary stakeholder-oriented CSR, managers are suggested to denote parts of earnings to charity and to people in need. Second, in order to create job satisfaction, firms should put a stronger emphasis on CSR practices. When considering job satisfaction, managers should treat their employees in a socially responsible way and fulfill their demands and rights and place this at the core of their CSR activities.

First, this study makes a contribution to the existing literature by classifying the four important CSR practices into two types from the perspective of stakeholder theory. By incorporating a series of CSR practices and the stakeholder theory, this study provides a comprehensive and reasonable CSR classification, which has not been considered by prior research. Second, this study adds to the literature by defining the construct of happiness management explicitly along with identifying the dimensions of happiness management. Third, to the best of the authors' knowledge, this is one of the first studies exploring the relationship between CSR and happiness management. Finally, this study is among the first to investigate the correlation between job satisfaction and happiness management.

Throughout the world, healthcare policy has committed to delivering integrated models of care. The interface between primary–secondary care has been identified as a particularly challenging area in this regard. To that end, this study aimed to examine the issue of integrated care from general practitioners’ (GPs) perspectives in Ireland.

This multimethod study involved a cross-sectional survey and semi-structured interviews with GPs in the Ireland East region. A total of 1,274 GPs were identified from publicly available data as practising in the region, of whom the study team were able to identify 430 GPs with email addresses. An email invite was sent to 430 potential participants asking them to complete a 34-item online questionnaire and, for those who were willing, an in-depth interview was conducted with a member of the study team.

In total, 116 GPs completed the survey. Most GPs felt that enhancing integration between primary and secondary care in Ireland was a priority (n = 109, 93.9%). Five themes concerning the state of integrated care and initiatives to improve matters were identified from semi-structured interviews with 12 GPs.

The uniqueness of this study is that it uses a multimethod approach to provide insight into current GP views on the state of integrated care in Ireland, as well as their perspectives on how to improve integration within the Irish healthcare system.

This paper investigates a problem in a reverse logistics (RLs) network to decide whether to dispose of unsold goods in primary stores or re-commercialize them in outlet centers. By deducting the costs associated with each policy from its revenue, this study aims to maximize the profit from managing unsold goods.

A new mixed-integer linear programming model has been developed to address the problem, which considers the selling prices of products in primary and secondary stores and the costs of transportation, cross-docking and returning unwanted items. As a result of uncertain nature of the cost and time parameters, gray numbers are used to deal with it. In addition, an innovative uncertain solution approach for gray programming problems is presented that considers objective function satisfaction level as an indicator of optimism.

According to the results, higher costs, including transportation, cross-docking and return costs, make sending goods to outlet centers unprofitable and more goods are disposed of in primary stores. Prices in primary and secondary stores heavily influence the number of discarded goods. Higher prices in primary stores result in more disposed of goods, while higher prices in secondary stores result in fewer. As a result of the proposed method, the objective function satisfaction level can be viewed as a measure of optimism.

An integral contribution of this study is developing a new mixed-integer linear programming model for selecting the appropriate goods for re-commercialization and choosing the best outlet center based on the products' price and total profit. Another novelty of the proposed model is considering the matching percentage of boxes with secondary stores’ desired product lists and the probability of returning goods due to non-compliance with delivery dates. Moreover, a new uncertain solution approach is developed to solve mathematical programming problems with gray parameters.

The burnout, stress, and work-life balance challenges faced by teachers have received renewed interest due to the myriad disruptions and changes to K-12 schooling brought about by the COVID-19 pandemic. Even prior to the pandemic, relatively little was known about teachers' time use outside of the classroom, the blurring of work and home boundaries, and how teachers compare to similar professionals in these regards. We use daily time-diary data from the American Time Use Survey (ATUS) for 3,168 teachers and 1,886 professionals in similarly prosocial occupations from 2003 to 2019 to examine occupational differences in time use. Compared to observationally similar non-teachers, teachers spend significantly more time volunteering at their workplace and completing work outside the workplace during the school year. On average, teachers spend 19 more minutes working outside of the workplace on weekdays than observably similar non-teachers and 38 more minutes on weekends. The weekend disparity is particularly large among secondary school teachers. This suggests that before the widespread switch to online and hybrid learning necessitated by the COVID-19 pandemic, teachers were already navigating blurrier work-life boundaries than their counterparts in similar professions. This has important implications for teacher turnover and for the effectiveness and wellness of teachers who remain in the profession.

As a result of both shifting social concerns and stricter legislation, many companies are seeking innovative and sustainable solutions for both primary and secondary packaging. The craft beer industry has made the most notable advancements with a variety of alternatives to the traditional secondary packaging (e.g. plastic rings) used to link beer cans. Yet, despite the impact packaging has on consumer purchase behavior and the environment, secondary packaging has received far less attention in the literature. This study aims to understand consumer perceptions of craft beer secondary packaging on consumers’ willingness to buy via the underlying mechanisms of perceived packaging innovation and sustainability.

A single-factor between-subjects experiment with four conditions (secondary packaging format: Pak-Tech holder, Keel Clip holder, Glue-Pack holder, Biodegradable holder) was conducted with 354 participants to test the hypothesized serial mediation model.

The results demonstrate that none of the secondary packaging styles had a direct effect on willingness to buy, meaning that the package style alone does not influence a consumer’s purchase decisions. Critically, the results also revealed indirect effects; specifically, the Keel Clip and Glue-Pack six-pack can holders were perceived as more innovative than the Pak-Tech holder, which in turn positively influenced perceptions of packaging sustainability and subsequent willingness to buy.

The authors’ results extend the research on sustainable secondary packaging and aids craft breweries along with other beverage producers in making informed decisions as the push for sustainable packaging becomes more prominent.

The primary goal of university education globally is to promote research, knowledge, and innovations instrumental for national development and societal transformation. In line with this goal, East African countries, namely Kenya, Uganda, and Tanzania have invested heavily in university education in the last 60 years since independence. The evidence of this is the increasing number of both private and public universities, and the number of students joining the institutions. While the expansion of university education is to be celebrated, it should not be taken for granted that this expansion indicates development. The purpose of this research was to assess the impact of university education on regional development in the three East African countries, that is, Kenya, Uganda, and Tanzania. Data were collected through historical analyses, database searches on electronic and printed sources, and interviews. The study found out that the three African countries have formulated the goals of education toward the achievement of development and that large budgets have been committed to educational expansion in the university in recent years. However, the impact of the universities in the development of the region expected through research and innovation is minimal because of major challenges that include expansion of access without adequate government funding; compromises quality; graduate unemployability and political interference; students’ unrest and strikes; weaknesses in earlier levels of education; regional, gender, and class inequalities; and misalignment of education, development, and contextual strengths. Proposed future strategies included the calls for governments to enhance regional consultations on development and education, the need for specialization in programs rather than duplication, enhancement of international collaborations and networking, rethinking the role of education in development within given contextual and environmental realities, and good governance and adequate funding of education.
