Theorizing Chinese lesson study from a cultural perspective
Authors: Chen Xiangming 
Published: August 2017

PurposeThe purpose of this paper is to examine the cultural roots of Chinese lesson study (LS) so as to account for its persistence in the Chinese education history as well as its importance in Chinese teacher professional development and student learning.Design/methodology/approachThe overarching research question is: “How can Chinese lesson study be theorized from a cultural perspective?” The sub-questions include: “What cultural features do Chinese teachers demonstrate in their LS activities? How can traditional Chinese cultural resources be utilized in explaining the existence and development of these features?” Based on a close reading of firsthand classic texts on Chinese cultural thoughts and related literature, the researchers collected data from Chinese teachers’ LS activities, stimulated recall interviews and focus groups, and related documents. An analysis is conducted with interplay among the theoretical framework, the data, and the researchers’ personal insights.FindingsThe findings of the study include three aspects. First, in terms of their actions, the Chinese teachers enact their understanding of teaching in public lessons through unity of knowing and doing (知行合一) more than conceptual explication. Second, with regard to their thinking, the Chinese teachers use practical reasoning (实践推理) in deliberate practice of repeated teaching through group inquiry and reflection. Third, a tendency of emulating those better than oneself (见贤思齐) is evident in novice teachers’ learning from “good” examples by expert teachers.Originality/valueThe revelation of these cultural features can not only contribute to a deeper understanding about the persistence and importance of LS in the Chinese education history, but also provide an example of analyzing LS from a cultural perspective to the world LS community.
Learning from the masters: Shanghai’s teacher-expertise infusion system
Authors: Cravens Xiu , Wang Jianjun 
Published: August 2017

Purpose
The urgency of improving the schools call for a distributed instructional leadership model where teachers are not just recipients of professional development, but also active leaders who are coaches and mentors for their peers. The purpose of this paper is to examine the teacher leadership development system in Shanghai, and identify pathways to constructing actionable models that develop and maximize instructional expertise.

Design/methodology/approach
This is a qualitative study. Purposive sampling was conducted to select four teaching-study groups from a frame that included all certified “expert teachers” from a large Shanghai district with about 9,000 teachers. Grounded theory approaches were used to understand “what actually happens in the teachers’ world.” Participative observations (of lesson delivering and collaborative decoding), semi-structured interviews, teachers’ reflective journal entries, and video recording of group work and lessons were the main measures of data collection.

Findings
Three key features of expertise infusion were identified: recognizing, differentiating, and labeling teacher expertise at multiple mastery levels; providing expert teachers with support and leadership responsibilities to lead practice-embedded and cross-school peer learning; and creating a roadmap for teachers to chart continuous learning pathways individually and build an enhanced content pedagogical knowledgebase collectively.

Originality/value
Results from this study provide the impetus for further exploration in how Shanghai continuously share and improve good teaching systemically, which could be informative to US schools and districts in their effort of redesigning professional development that maximizes available expertise among teachers and stimulates teacher-led action research for student learning.
Corrosion resistance and mechanical characteristics of dual-phase steel B500c, after shot blasting processes
Authors: Drakakaki Argyro , Apostolopoulos Charis , Katsaounis Alexandros , Bjorn Hasa 
Published: August 2017

Purpose
Corrosive agent constitutes a major problem for constructions located in coastal areas, since it keeps affecting their durability. This phenomenon, in synergy with moisture and high temperatures, leads to premature deterioration of the structures. Under these conditions, the need for management of the problem of resistance of steel against corrosion is an issue of paramount importance and a challenge to the structural integrity and reliability. The paper aims to discuss these issues.

Design/methodology/approach
The need for management of the problem of resistance of steel against corrosion is an issue of paramount importance and a challenge to the structural integrity and reliability. In the present study, an effort was made to increase the corrosion resistance of the high strength and ductility dual-phase steel B500c category, with the use of different shot blasting processes, without any interference in the chemical composition or in the production mode. In particular, shot blasting treatment was used for both cleaning and creating compressive stresses on the surface of steel bars, according to the pertinent protocols. The modified samples were studied via both conventional characterization methods and electrochemical techniques.

Findings
Through the whole surface treatment process of B500c steel, a positive impact came about not only the corrosion resistance, but also the mechanical performance.

Originality/value
Shot blasting process aims to increase the corrosion resistance of high ductility dual-phase steel (B500c), without any interference in the chemical composition or in the production mode.
The digitization of health care retailing
Authors: Rosenbaum Mark Scott , Ramírez Germán Contreras , Edwards Karen , Kim Jiyeon , Campbell Jeffery M. , Bickle Marianne C. 
Published: August 2017

Purpose
This paper aims to offer insights into the impact of digitization technology on consumer goods manufacturers and retail organizations. The authors propose that the “next phase” of digitization will entail the employment of digitization technology to offer consumers personalized product offerings and recommendations based on their internal biomarkers.

Design/methodology/approach
The authors draw on past investigations into digitization and their retailing experience to speculate on how the next phase of digitization will affect both consumer goods manufacturers and retailers.

Findings
The next phase of digitization will entail the use of nutrigenomics (DNA sequencing), exhaled breath analysis, fitness tracker devices, sensory patches, radio frequency identification tags and quantum ID tags to create customized and recommend products, and support product-to-customer communication regarding authenticity.

Research limitations/implications
Consumers will increasingly rely on technology to inform them of their bodily needs and to receive personalized solutions to help satisfy those needs. Consumer behavior theories must be reconsidered because consumers will become more passive participants in retail consumption as they rely on technology for need-recognition and product-fulfillment.

Social implications
Digitization technologies that use consumers’ biomarkers for new product creation or product recommendation raise new risks and uncertainty. For example, the legal implications of an incorrect product recommendation based on customer biomarkers are unknown. Furthermore, retailers would need to maintain data privacy of biomarker data and be responsible for data breaches.

Originality/value
The research explores how digitization will affect consumers’ in-store experiences with consumer goods products.
Benevolent leadership, perceived supervisory support, and subordinates’ performance
Authors: Chan Simon C.H. 
Published: August 2017

PurposeThe purpose of this paper is to examine the mediating role of perceived supervisory support (PSS) and the moderating role of psychological empowerment between benevolent leadership and subordinates’ objective performance (from appraisal report evaluated by immediate supervisors after a year) over time.Design/methodology/approachA sample of 312 employees in a manufacturing plant in the People’s Republic of China was collected. Descriptive statistics and linear regression analyses were used to analyze the data.FindingsThe results indicated that PSS mediated the relationship between benevolent leadership and subordinates’ objective performance. This positive relationship of benevolent leadership and subordinates’ performance was stronger when supervisors exhibited higher levels of psychological empowerment.Research limitations/implicationsThe main limitation of this study is that the sample was collected from the administrative staff of a manufacturing plant in China. The results may not be generalized in different contexts and professions, given the contextually and culturally specific setting.Practical implicationsBenevolent leadership appears to be effective in driving the work performance of subordinates.Originality/valueThe relationships among benevolent leadership, PSS, and work performance of subordinates have shown significant explanation.
The impact of social norms on female corporate board membership inclusion
Authors: Dewally Michaël , Flaherty Susan M.V. , Tomasi Stella 
Published: August 2017

Purpose
The purpose of this paper is to document that religious adherence in the county of the corporate headquarter and educational attainment of the female director pool near the firm headquarters are influential to the likely addition of female corporate board directors.

Design/methodology/approach
The sample covers 1,630 unique firms and 30,369 unique directors covering a ten-year period to investigate the effects of religiosity and educational attainment.

Findings
The analysis reveals that while the number of women has increased in general terms, this change is mostly limited to boards that are increasing in size. Women do not tend to replace exiting male board members but are appointed when the board size grows. Therefore, while the number of women is increasing in absolute terms, they are not increasing in relative terms. In areas where religiosity is high, as measured by church affiliation and attendance, female participation in the boardroom is lower and a more educated and qualified female population leads to higher board participation. These effects supersede any regional effects.

Originality/value
The study adds insights into corporate board dynamic, providing new evidence concerning the impact of local conditions on board composition as well as additional information concerning the interplay of board dynamics and female board representation.
Board and audit committee effectiveness in the post-ASX Corporate Governance Principles and Recommendations era
Authors: Safari Maryam 
Published: August 2017

PurposeThe purpose of this paper is to contribute to the corporate governance literature by examining the aggregate effect of board and audit committee characteristics on earnings management practices, particularly in the period following the introduction of the second edition of the Australian Securities Exchange (ASX) Corporate Governance Principles and Recommendations.Design/methodology/approachThis paper begins by embarking on an extensive review of extant empirical research on boards of directors and audit committees. Then, the paper reports on the use of a quantitative analysis approach to specify the relationship between board and audit committee characteristics (introduced by the ASX Corporate Governance Council) and the level of absolute discretionary accruals as a proxy for earnings management.FindingsThe findings suggest that greater compliance with board and audit committee principles is linked to lower earnings management, indicating that deliberate structuring of boards and audit committees is an effective approach for enhancing a firm’s financial reporting quality and providing support for the efficacy of the second edition of principles and recommendations related to boards and audit committees suggested by the ASX Corporate Governance Council.Practical implicationsThis study significantly extends the literature and has notable implications for financial reporting regulators, as the findings regarding the monitoring role of boards and audit committees should be beneficial for future revisions of corporate governance principles and recommendations.Originality/valueThis study focuses on the aggregate effect of board characteristics recommended by the Australian Corporate Governance Council on earnings management practices, and the results support the effectiveness of the board and audit committee characteristics recommended by the ASX Corporate Governance Council. New directions for future improvements to the principles and recommendations are identified.
Board structure, board committees and corporate performance in Russia
Authors: Berezinets Irina , Ilina Yulia , Cherkasskaya Anna 
Published: August 2017

PurposeThe purpose of this paper is to investigate the link between board structure and performance of public companies in Russia – an emerging market with unique institutional background and a variability of corporate governance (CG) practices across its companies.Design/methodology/approachPanel data analysis was applied on a sample of 207 Russian companies that frequently traded in the Russian Trading System during the period 2007-2011, in order to test hypotheses on the relationships between board size, board independence, gender diversity, presence of board committees and financial performance, as measured by Tobin’sQ.FindingsThe results show a positive relationship between Tobin’sQand the board’s gender diversity. The analysis demonstrates that smaller and bigger boards are associated with a greater Tobin’sQvalue.Originality/valueThe findings provide additional evidence of how board structure is related to its effectiveness and corporate performance in countries with concentrated ownership, highly variable CG practices and a lack of proper implementation of corporate law and governance codes. The paper contributes to the existing empirical evidence on the advantages of small and large-sized boards and on gender diversity, and is the first investigating the relationship between Russian companies’ board committees and market-based performance. The results regarding board independence and committees suggest that these mechanisms are still not widely recognized for their role in CG and company performance in Russia.

Considering pollution in the higher education (HE) service ecosystem
Authors: Díaz-Méndez Montserrat , Saren Michael , Gummesson Evert 
Published: August 2017

Purpose
From a service ecosystem perspective, the purpose of this paper is to examine students’ evaluation surveys as a tool used by most higher education (HE) institutions worldwide to measure teaching quality with consequences for tenure and promotion.

Design/methodology/approach
This study is based on the service-dominant (S-D) logic and specifically on the service ecosystem approach. Through an in-depth literature review and analysis the authors explore the effect of student evaluation surveys on the value co-creation process, describe the role they play in the HE ecosystem and critically evaluate their efficacy. The research is based on empirical data from the literature and previous studies findings.

Findings
The literature review highlights the detrimental consequences of the use of students’ evaluation surveys for teachers and students and for the rest of actors of this service. The authors argue that institutions should embrace a service ecosystem perspective based on S-D logic. The authors highlight the role of institutions as moderators of the interactions between actors and, finally, the authors have introduced the concept of “service ecosystem pollution” which the authors define as the presence or introduction of disruptive elements in the service ecosystem adversely affecting the nature of value co-creation.

Practical implications
This study emphasizes the importance for HE institutions to embrace a service ecosystem approach so as to foster and preserve the value co-creation processes taking place within the interactions among the HE actors. Conclusions drawn from this paper suggest that HE institutions should focus on strategies such as investing in improving students’ and teachers’ operant resources rather than polluting the HE service ecosystem with the use of students’ evaluation surveys.

Originality/value
Hitherto there are no studies analyzing the tools HE institutions use to measure teaching quality from a service ecosystem perspective. The study is especially valuable due to the consequences and the use of these measures entails for teachers, students and society.
Divergence of Cash Flow and Voting Rights, Opacity, and Stock Price Crash Risk: International Evidence
Authors: HONG HYUN A. , KIM JEONG‐BON , WELKER MICHAEL 
Published: August 2017

ABSTRACTThis study investigates whether and how the deviation of cash flow rights (ownership) from voting rights (control), or simply the ownership‐control wedge, influences the likelihood that extreme negative outliers occur in stock return distributions, which we refer to as stock price crash risk. We do so using a comprehensive panel data set of firms with a dual‐class share structure from 20 countries around the world for the period of 1995–2007. We predict and find that opaque firms with a large wedge are more crash prone than opaque firms with a small wedge. In addition, we predict and find that the positive relation between the wedge and crash risk is less pronounced for firms with more effective external monitoring and for firms with greater growth opportunities. The results of this study are broadly consistent with Jin and Myers’s theory that agency costs, combined with opacity, exacerbate stock price crash risk.
Effect of Micronutrient Powder Addition on Sensory Properties of Foods for Older Adults
Authors: Field Katherine M. , Duncan Alison M. , Keller Heather H. , Stark Ken D. , Duizer Lisa M. 
Published: August 2017

AbstractMicronutrient fortification can improve nutrient intake of older adults in long‐term care. However, previous studies indicate that micronutrient fortification can alter food sensory attributes and, potentially, consumer liking. Others have found no effect of fortification on liking. This research investigates the effect of micronutrient powder addition on the sensory properties of selected foods commonly served in long‐term care. A micronutrient powder containing 9 vitamins and 3 minerals was added to tomato soup and oatmeal at different levels. Using projective mapping, changes in sensory properties were observed with powder addition. Descriptive analysis, used to quantify these changes, showed that both the tomato soup and oatmeal had reduced flavor as the amount of added micronutrient powder increased. Oatmeal also showed changes in texture with fortification. Consumer liking scores for tomato soup showed that micronutrient addition affected liking when 100% of a daily dose was added into the soup. Addition of 50% of the daily dose did not affect liking. Oatmeal liking did not differ between fortified and unfortified samples.Practical ApplicationResults from this research can be used to decide whether a micronutrient powder of selected vitamins and minerals can be added to foods served to older adults in long‐term care. Although sensory properties of the foods will be altered, fortification of both tomato soup and oatmeal with the developed powder is possible without reducing consumer liking to the point where it is disliked.
Molecular Weight Affected Antioxidant, Hypoglycemic and Hypotensive Activities of Cold Water Extract fromPleurotus citrinopileatus

Published: August 2017

AbstractCold water extract ofP. citrinopileatus(CWEPC) was fractioned into 4 fractions, PC‐I (<1 kDa), PC‐II (1‐3.5 kDa), PC‐III (3.5‐10 kDa), and PC‐IV (>10 kDa), by ultrafiltration. The antioxidant activities, the inhibition of pancreatic α‐amylase, intestinal α‐glucosidase, and hypertension‐linked angiotensin converting enzyme (ACE), as well as the contents of polysaccharides, protein, and phenolic compounds of 4 fractions were determined. The results showed that lower MW fractions exerted a higher antioxidant activity, which was correlated to phenolic contents. The high molecular fraction (PC‐IV) exhibited significantly higher inhibitory activity on α‐amylase, α‐glucosidase, and ACE compared to CWEPC and the other 3 lower MW fractions (<10 kDa), which was more related to protein contents. The inhibition capability of CWEPC and PC‐IV on α‐amylase activity was 1/13.4 to 1/2.7 relative to that of acarbose, respectively. Kinetic data revealed that PC‐IV fraction followed a noncompetitive inhibition pattern on α‐glucosidase activity. The study demonstrated that various MW fractions and types of components contribute to different biological functions ofP. citrinopileatusand it is protein constituents but not peptides responsible for the hypoglycemic potential of CWEPC.
