A city is a spatial carrier of innovation activities. Improving the level of urban innovation can play a significant supporting role in building an innovative country. China began to implement the innovative city pilot policy in 2008 and continued to expand the policy into more areas for exploring the path of innovative urban development with Chinese characteristics and improving urban innovation.

Based on mechanism analysis, this paper used the panel data of 269 cities from 2003 to 2016 to empirically test the effect of the pilot policy on the level of urban innovation by using different methods, such as the difference-in-differences model.

The results show that the innovative city pilot policy significantly improves the level of urban innovation. However, according to the findings of the heterogeneity analysis, the effect of the pilot policy on improving the innovation level in direct-controlled municipalities, provincial capitals and sub-provincial cities is weaker than that in ordinary cities, and the effect of the pilot policy on improving the innovation level in cities with a higher quality of science and education resources is weaker than that in cities with lower quality of science and education resources.

Moreover, as the level of urban innovation increases, the effect of the pilot policy on improving the level of urban innovation is an asymmetric inverted V shape, which means the effect is first strengthened and then weakened. The research also finds that the locational heterogeneity of the pilot policy for improving the level of urban innovation is not notable. In addition, the innovative city pilot policy can strengthen the government's strategic guidance, promote the concentration of talent, incentivize corporate investment and optimize the innovation environment, having a positive impact on urban innovation. Moreover, the effect of concentration of talent and the effect of corporate investment incentive are the important reasons for the pilot policy to promote the improvement of the level of urban innovation.

Total quality management (TQM) has long been viewed as a strategy to attain business excellence. However, it is relatively a new concept in the context of emerging economies. Particularly, this is far beyond the reality in the context of African countries, in general. The purpose of this paper is to study the current state of TQM implementation in the manufacturing industry of Ethiopia (MIE). The study also focuses on several comparisons, between large and medium companies, and ISO and non-ISO companies with regard to the adoption of TQM practices.

The study draws on top- and middle-level managers from sample companies. Data were collected using a structured survey questionnaire. After testing scale reliability and validity, descriptive and factor analysis were used for the data analysis.

The findings, in general, indicated that Ethiopian manufacturers have implemented TQM at a moderate level (grand mean value of 2.86 on 0–5 scale). It is revealed that ISO companies are significantly adopted TQM practices than non-ISO companies, whereas no difference was found between large and medium companies.

Given the importance of understanding TQM and paucity of research on the topic in Ethiopia, the study provides practical insights and groundwork that can guide practitioners to understand the drivers of TQM in the region. Particularly, the study is useful to plan corrective actions on practices that are likely to obstruct TQM implementation in the MIE. Moreover, the study adds to the empirical literature that may yield important insights on TQM for under-researched emerging economies, particularly for the eastern part of Africa, where nations share similar cross-cultural norms, economic, social and ethnic settings.

The authorship authentication (AA) problem is concerned with correctly attributing a text document to its corresponding author. Historically, this problem has been the focus of various studies focusing on the intuitive idea that each author has a unique style that can be captured using stylometric features (SF). Another approach to this problem, known as the bag-of-words (BOW) approach, uses keywords occurrences/frequencies in each document to identify its author. Unlike the first one, this approach is more language-independent. This paper aims to study and compare both approaches focusing on the Arabic language which is still largely understudied despite its importance.

Being a supervised learning problem, the authors start by collecting a very large data set of Arabic documents to be used for training and testing purposes. For the SF approach, they compute hundreds of SF, whereas, for the BOW approach, the popular term frequency-inverse document frequency technique is used. Both approaches are compared under various settings.

The results show that the SF approach, which is much cheaper to train, can generate more accurate results under most settings.

Numerous advantages of efficiently solving the AA problem are obtained in different fields of academia as well as the industry including literature, security, forensics, electronic markets and trading, etc. Another practical implication of this work is the public release of its sources. Specifically, some of the SF can be very useful for other problems such as sentiment analysis.

This is the first study of its kind to compare the SF and BOW approaches for authorship analysis of Arabic articles. Moreover, many of the computed SF are novel, while other features are inspired by the literature. As SF are language-dependent and most existing papers focus on English, extra effort must be invested to adapt such features to Arabic text.

While the structural changes that have taken place in the labour markets of the industrialised world over the past decades are well documented, less is known about how individuals respond to this changing environment. This includes the extent of intersectoral mobility during the work career, skill differentials in mobility, the impact of the type of training on mobility and changes in mobility patterns over a long period of time. Against this backdrop, the purpose of this paper is to examine intersectoral labour mobility during the first 15 years of working careers in Sweden and West Germany. The analyses show that individuals in both countries tend to move away from industry into other sectors during their careers, but that this tendency is rather weak. While there are some mobility differences among educational categories, the differences between transition probabilities of German apprentices and Swedish vocational school students are insignificant. In the face of the massive transformation of employment structures, the importance of variation in the curricula is probably minuscule.

The purpose of this article is to report findings from a national study of primary headteachers in their second headship in England. This investigated their reasons for moving schools, their choice of second school and a comparison of their experiences as heads of the two schools.

The research design involved a national representative survey of primary school headteachers who were in a headship beyond their first. Questionnaire responses were obtained from 86 primary headteachers: a 74 per cent response rate. Follow‐up telephone interviews with 20 of them obtained more detailed responses on the research questions.

The reasons that heads gave for taking a second headship fell into three groups – personal, school and external. The over‐riding reasons were to provide a fresh challenge and prevent feelings of stagnation. Movement between schools was complex and the clearest overall trend was a move to larger schools. Heads generally considered themselves more effective in their second school than their first and there were many accounts of the re‐energising effect of taking on a new post.

The findings suggest that second headship should be considered as a valuable means of contributing to the continuing development of headteachers. Headteachers should consider a second headship as a possible extension to their headship career. They may need to plan their career before and during their first headship in order to obtain their desired second headship.

This is the first large‐scale study of headteachers in a second headship. The numbers of headteachers choosing to move to a second headship and their positive experiences suggest that further stages should be added to the current conceptualisations of the career of the headteacher.

This study investigates the relationship between self-leadership and the work performance of gig workers as moderated by perceived organizational support and mediated by work engagement.

Linear regression and the Process macro by Hayes were used to examine the hypothesized model, on a data set of 384 gig workers.

The outcomes indicated a positive relationship between the self-leadership strategies of the freelancers and their work performance. The association of self-leadership and work performance was moderated by perceived organizational support and partially mediated by work engagement.

This study responds to the need for exploration of the moderation and mediating mechanisms through which self-leadership influences how gig workers perform at work.

This case can be used to develop students’ understanding of optimization and the development of a linear programing (LP) model and solution. The instructor’s manual provides one possible solution based on the LP tools available in excel.

This case is based on real events at waypoint adventure and is derived from the authors’ experience consulting with this organization as they sought to improve pricing and scholarship management.

A young non-profit organization serving the disabled community in Boston sought growth but lacked clarity and consistency in their program pricing and scholarship structures. The case analysis centers on revising program prices to achieve specific cost and revenue requirements and determining a scholarship policy that will maximize participation in their outdoor adventure programing for the upcoming year. This case allows the exploration of optimization with an atypical objective, as the organization seeks to maximize participant engagement rather than profit.

The target audience includes upper-level undergraduate and MBA or early graduate-level students studying the optimization techniques of operations management, revenue and pricing management or marketing. The case would also be useful for discussing the challenges faced by non-profits and the non-traditional objectives that can arise for these organizations.
