Authors: Mazurek-Kusiak Anna Katarzyna , Kobyłka Agata , Sawicki Bogusław 
Published: August 2019

PurposeThe purpose of this paper is to assess nutritional habits and body composition parameters in the group of Polish pupils and students.Design/methodology/approachThe study was conducted by the body composition analysis using the biological impedance method applying TANITA analyzer and diagnostic survey method using standardized direct interview with selected elements of the Sarzynska test. The research was carried out in various regions of Poland on a group of 1,000 pupils and students, using a targeted sample selection in the following subgroups: 250 middle school pupils, 250 high school students, 250 students living in a family home and 250 students living in an academic home.FindingsSignificantly the worst nutritional habits according to the Sarzynska test are shown by students living in academic home. As many as 21.6 percent of them eat very badly, while only 10.4 percent of students living in a family home eat very badly. This may indicate a lack of conditions, skills and time to prepare healthy meals, but also the lack of parental control in relation to what their child eats. The middle school pupils eat the healthiest meals (64.4 percent). It can be seen the regularity that the older the child is, the smaller the percentage of people in the healthy group.Research limitations/implicationsA research limitation was the little sample size of the study (1,000 person) and participants might have felt uncomfortable during research.Practical implicationsPeople planning class schedules should also plan breaks for a full-value meal. It is necessary to organize affordable courses that would teach simple and fast food preparation that does not require a lot of equipment and little popular ingredients. It would also be necessary to draw parents’ attention to excessive care and the fact that not allowing children to “experiment” in the kitchen may arouse in them the reluctance and fear of cooking.Social implicationsAmong students, one should conduct universal education regarding a healthy lifestyle, which should focus on the subject of proper nutrition and physical activity, because there are no systemic solutions that would include adults. In order to improve nutritional habits, social rooms in academic homes should be adjusted so that students have the conditions to prepare nutritious meals, as well as provide access to canteens, where students would receive a reasonable meal at a reasonable price. The qualifications of the staff working there should also be improved.Originality/valueThe present study adds to the existing body of literature nutritional habits and body composition parameters in the group of Polish pupils and students. The results are the foundation for providing recommendations to policy makers, universitets, schools, food organizations and parents.
TQM, SCM and operational performance: an empirical study of Indian pharmaceutical industry
Authors: Sharma Sanjay , Modgil Sachin 
Published: August 2019

PurposeThe purpose of this paper is to investigate the impact of total quality management (TQM) and supply chain management (SCM) practices on operational performance, and their interlinkage between each other.Design/methodology/approachConstructs those are critical to pharmaceutical quality and supply chain have been identified with the help of literature and experts from industry. The impact of TQM practices on supply chain practices and on operational performance has been evaluated. Similarly, the impact of supply chain practices on operational performance has been evaluated. Further, alternate models are tested and evaluated through structural equation modeling.FindingsIt was observed during testing of alternate models that TQM practices have a direct impact on operational performance. However, TQM practices also directly impact supply chain components, which, in turn, influence overall operational performance. In comparison of alternate models, the model in which TQM practices affect supply chain practices and supply chain practices further affect the operational performance is found most appropriate.Practical implicationsThis study provides some useful implications from industry point of view. TQM practices are critical to pharmaceutical industry. TQM practices are the core of attaining a smooth supply chain, which will have greater impact to achieve operational performance. Strategic supplier partnership, procurement management, information sharing, and quality and inventory management practices are driven by TQM practices. This tri-linkage helps to achieve the desired operational performance.Originality/valueThere are very limited studies that have considered both the areas together to achieve better operational performance. In pharmaceutical industry, both TQM and SCM are the critical areas for any organization to drive its growth.
Enterprise risk management and bow ties: going beyond patient safety
Authors: Elamir Hossam 
Published: August 2019

Purpose
The growing importance of risk management programmes and practices in different industries has given rise to a new risk management approach, i.e. enterprise risk management. The purpose of this paper is to better understand the necessity, benefit, approaches and methodologies of managing risks in healthcare. It compares and contrasts between the traditional and enterprise risk management approaches within the healthcare context. In addition, it introduces bow tie methodology, a prospective risk assessment tool proposed by the American Society for Healthcare Risk Management as a visual risk management tool used in enterprise risk management.

Design/methodology/approach
This is a critical review of published literature on the topics of governance, patient safety, risk management, enterprise risk management and bow tie, which aims to draw a link between them and find the benefits behind their adoption.

Findings
Enterprise risk management is a generic holistic approach that extends the benefits of risk management programme beyond the traditional insurable hazards and/or losses. In addition, the bow tie methodology is a barrier-based risk analysis and management tool used in enterprise risk management for critical events related to the relevant day-to-day operations. It is a visual risk assessment tool which is used in many higher reliability industries. Nevertheless, enterprise risk management and bow ties are reported with limited use in healthcare.

Originality/value
The paper suggests the applicability and usefulness of enterprise risk management to healthcare, and proposes the bow tie methodology as a proactive barrier-based risk management tool valid for enterprise risk management implementation in healthcare.
Estimating market power in the Chinese pork-packing industry: a structural approach
Authors: Lan Hao , Wang Xiaojin 
Published: August 2019

Purpose
The purpose of this paper is to investigate market power in the Chinese pork supply chain. The authors aim to explain why a steady rise in prices is observed in the sector, apart from existing evidence on incomplete/asymmetric cost pass-through and concerns of growing concentration and consolidation in the sector.

Design/methodology/approach
This study uses a new empirical industrial organization model for both oligopoly and oligopsony power to measure the degree of market power exerted on consumers and hog farmers simultaneously.

Findings
By examining annual panel data across provinces in China, the authors find that both oligopoly and oligopsony powers exist in the pork supply chain. In particular, the authors determine that a higher degree of market power is found to influence prices paid to hog farmers than prices paid by pork consumers. Estimates of key elasticities in the Chinese pork supply chain are also updated based on the structural model estimation and the latest data.

Research limitations/implications
Due to the lack of data at a more granular level of geography, the authors are only able to estimate market power by three major economic regions.

Practical implications
The findings provide useful information for future policy analyses of Chinese food markets. First, the pork-packing industry should be of great concern in terms of market power and its influence on consumers’ and farmers’ welfare. It is essential to take into consideration market power in the pork supply chain before making any public policy regarding the pork market. Furthermore, following economic theory and experience from developed countries, large meat packers will eventually vertically control hog farmers given their stronger oligopsony power over the upstream. Vertical integration may be the next important issue in terms of food market competition. Finally, the results may also draw the government’s attention to investigating market competition in all major food markets.

Originality/value
The empirical evidence draws attention to the issue of food market competition in one of the largest and most important meat-packing markets in China. The authors hope to encourage further discussions on pork and hog market regulations and related public policies.
Economic policy uncertainty and grain futures price volatility: evidence from China
Authors: Xiao Xiaoyong , Tian Qingsong , Hou Shuxia , Li Chongguang 
Published: August 2019

PurposeThe purpose of this paper is to investigate the influence of economic policy uncertainty (EPU) on China’s grain futures prices. Related literature has discussed several factors contributing to the dramatic boom and bust in China’s grain futures prices, but has overlooked the influence of EPU.Design/methodology/approachThe study employs a newly developed time-varying parameter vector autoregressive model to study and contrast the impact of different types of uncertainty on China’s grain futures prices. The directional volatility spillover index is used to measure the impact of EPU on China’s grain futures prices and compare the differences among commodities.FindingsThe results show that EPU affects China’s grain futures prices significantly. The 2008 global financial crisis had stronger influence on China’s grain futures prices than other types of uncertainty. Furthermore, EPU has smaller influence on wheat futures price than on maize and soybean. The Chinese Government interventions may be the reason for this difference.Originality/valueThis study addresses the lack of empirical investigation on the influence of EPU on China’s grain futures price volatility.
China’s anti-corruption campaign, political connections and private firms’ debt financing
Authors: Hu Yiming , Xu Mingxia 
Published: August 2019

Purpose
The purpose of this paper is to shed light on the deleveraging impact of the anti-corruption campaign since the 18th National Congress of the Communist Party of China (CPC) on private firms with political connections, relative to those without political connections.

Design/methodology/approach
In this paper, taking the anti-corruption campaign employed from the end of 2012 as an exogenous shock, the authors design a quasi-experiment difference-in-difference approach to examine how the loss and failure of political connections impacts private firms’ debt financing.

Findings
The authors find that the loss and failure of political connections following the anti-corruption campaign since the 18th CPC National Congress causes the yearly new debt ratios of treatment firms with political connections to decrease, relative to those of control firms without political connections. This outcome is more pronounced for provinces with more cadres excluded in the anti-corruption campaign since the 18th CPC National Congress, which rendered politically connected firms susceptible to lose connections with central or provincial cadres. To explore the mechanism, the authors find that following the anti-corruption campaign since the 18th CPC National Congress, politically connected firms limit rent-seeking activities, whereas resource acquisition is weakened. The authors also find that the impact of the anti-corruption campaign since the 18th CPC National Congress on the debt financing of politically connected firms, relative to their counterparts, is more pronounced for groups with high levels of information asymmetry and for less explicit guarantee groups. Finally, politically connected firms are more likely to be dominated by internal funds in dealing with a loss of advantages in debt financing, compared with their counterparts without political connections.

Research limitations/implications
The findings in this study suggest that the loss or failure of previous political connections following Xi’s anti-corruption campaign make politically connected firms lose the advantages in debt financing through the rent-seeking, resource acquisition, information asymmetry, implicit guarantee channels, which provide new evidence for research on the impact of the anti-corruption campaign since the 18th CPC National Congress on private firms’ financing behaviors via the loss or failure of existing political connections.

Practical implications
The findings in the study will have some inspiration for policy makers and entrepreneur.

Originality/value
This study provides new evidence on the different impacts of Xi’s anti-corruption campaign on private firm’s debt financing between politically connected and unconnected firms.
Transnational crisis translation: social media and forced migration
Authors: Marlowe Jay 
Published: August 2019

Purpose
The purpose of this paper is to outline how refugees’ transnational networks and online relationships facilitated through social media provide access to timely and trusted translated information in disaster settings.

Design/methodology/approach
The study is a digital ethnography of resettled refugees’ practices of transnational care and support through social media that took place over 12 months. It involved conducting 50 semi-structured interviews and collecting 472 online social media diaries with 15 participants. Data analysis was conducted through constructivist grounded theory.

Findings
Transnational networks are increasingly part of refugees’ everyday lives that illustrate how social media platforms can provide forms of transnational care and access to trusted translated communications during times of crisis. The paper discusses the possibilities and cautions of such support.

Research limitations/implications
The small number of participants limits the ability to make generalised claims about refugees and transnational possibilities for reducing disaster risk. However, the reality that social media effectively provide a bridge between “here” and “there” signals the importance of incorporating these considerations as a form of transnational disaster risk reduction.

Practical implications
The project highlights from policy and practice standpoints, how transnational networks and social media can be used to improve disaster communications and translation. This focus is achieved through examining the usability, accessibility and affordability of digital communication technologies for forced migrants.

Originality/value
Few studies focus on refugees and disaster risk reduction. This is particularly the case as it relates to the roles of transnational networks, which have increasing everyday interactions in countries that provide refugee resettlement programmes.
Numerical simulation for entropy generation in peristaltic flow with single and multi-wall carbon nanotubes
Authors: Ijaz Khan Muhammad , Farooq Shahid , Hayat Tasawar , Shah Faisal , Alsaedi Ahmed 
Published: August 2019

Purpose
The novel mechanical, chemical and thermodynamics characteristics of both single- and multi-wall carbon nanotubes (CNTs) make them a subject of much attention for the scientists and engineers from all domains. Fluid flows subject to CNTs are significant in biomedical engineering, energy storage systems, domestic and industrial cooling, automobile industries and solar energy collectors, etc. Keeping such effectiveness of CNTs in mind, this paper aims to examine peristaltic flow subject to CNTs in an asymmetric tapered channel. Both single and multiple walls CNTs are considered. The viscosity of nanomaterial depends on nanoparticles volume fraction and temperature. Total entropy rate through second law of thermodynamics is calculated. Heat source/sink and nonlinear heat flux are accounted.

Design/methodology/approach
The complicated flow expressions are simplified through lubrication approach. The velocity, temperature and entropy expressions are numerically solved by the built-in-shooting method.

Findings
The solutions for entropy generation, temperature and velocity are plotted, and the influences of pertinent variables are examined. The authors noticed that entropy generation is an increasing function of the Brinkman number.

Originality/value
The originality of this work is to communicate peristaltic CNTs-based nanomaterial peristaltic flow of viscous fluid in an asymmetric channel. No such consideration is yet published in the literature.
A generalised model for electro-osmotic flow in porous media
Authors: Di Fraia Simona , Nithiarasu P. 
Published: August 2019

Purpose
This study aims at developing a comprehensive model for the analysis of electro-osmotic flow (EOF) through a fluid-saturated porous medium. To fully understand and exploit a number of applications, such a model for EOF through porous media is essential.

Design/methodology/approach
The proposed model is based on a generalised set of governing equations used for modelling flow through fluid saturated porous media. These equations are modified to incorporate appropriate modifications to represent electro-osmosis (EO). The model is solved through the finite element method (FEM). The validity of the proposed numerical model is demonstrated by comparing the numerical results of internal potential and velocity distribution with corresponding analytical expressions. The model introduced is also used to carry out a sensitivity analysis of the main parameters that control EOF.

Findings
The analysis carried out confirms that EO in free channels without porous obstruction is effective only at small scales, as largely discussed in the available literature. Using porous media makes EO independent of the channel scale. Indeed, as the channel size increases, the presence of the charged porous medium is essential to induce fluid flow. Moreover, results demonstrate that flow is significantly affected by the characteristics of the porous medium, such as particle size, and by the zeta potential acting on the charged surfaces.

Originality/value
To the best of the authors’ knowledge, a comprehensive FEM model, based on the generalised equations to simulate EOF in porous media, is proposed here for the first time.
Developing a generic retail business model – a qualitative comparative study
Authors: Haas Yvonne 
Published: August 2019

PurposeGlobal trends like digitalization and verticalization increase the complexity within the retail industry and decrease the explanatory power of prevailing retail concepts. This paper responds to the call for new ways of understanding retailers’ business activities. The purpose of this paper is to structure and stimulate the emerging conceptual debate about retail business models (RBM) by developing a literature-based and empirically-substantiated generic retail business model framework (generic RBM).Design/methodology/approachThe research is based on a systematic literature review and a qualitative study with 16 expert interviews in the German retail industry.FindingsThe paper identifies six core elements and respective sub-elements of a generic RBM. Contrasting the literature with empirical data, it confirms some common elements (e.g. “value proposition”) but invalidates others (e.g. “organization” or “governance”). The empirical findings add retail specifics like “horizontal integration,” “vertical integration” and “partners and networks” as core elements of a generic RBM.Originality/valueThe paper is the first to develop a generic RBM based on a systematic literature review and an empirical study across retailers. The resulting generic RBM can be used as a retail concept for systemizing and typifying the appearances of retailers in retailing theory. It can also be used for building, analyzing and comparing RBMs in retailing practice. The paper further provides a guideline for generic business model design with a hybrid approach based on literature and qualitative data.
“Does the poor matter” in pro-poor driven sub-Saharan African cities? towards progressive and inclusive pro-poor tourism
Authors: Musavengane Regis , Siakwah Pius , Leonard Llewellyn 
Published: August 2019

PurposeThe purpose of this paper is to question the extent to which Sub-Saharan African cities are progressing towards promoting pro-poor economies through pro-poor tourism (PPT). It specifically examines how African cities are resilient towards attaining sustainable urban tourism destinations in light of high urbanization.Design/methodology/approachThe methodological framework is interpretive in nature and qualitative in an operational form. It uses meta-synthesis to evaluate the causal relationships observed within Sub-Saharan African pro-poor economies to enhance PPT approaches, using Accra, Ghana, Johannesburg, South Africa, and Harare, Zimbabwe, as case studies.FindingsTourism development in Sub-Saharan Africa has been dominantly underpinned by neoliberal development strategies which threaten the sustainability of tourism in African cities.Research limitations/implicationsThe study is limited to three Sub-Saharan African countries. Further studies may need to be done in other developing countries.Practical implicationsIt argues for good governance through sustainability institutionalization which strengthens the regulative mechanisms, processes and organizational culture. Inclusive tourism approaches that are resilient-centered have the potential to promote urban tourism in Sub-Saharan African cities. These findings contribute to the building of strong and inclusive Institutions for Sustainable Development in the Sub-Saharan African cities to alleviate poverty.Social implicationsThese findings contribute to the building of strong and inclusive institutions for sustainable development in the Sub-Saharan African cities to alleviate poverty.Originality/valueThe “poor” are always within the communities, and it takes a community to minimise the impact of poverty among the populace. The study is conducted at a pertinent time when most African government’s development policies are pro-poor driven. Though African cities provide opportunities of growth, they are regarded as centres of high inequality.
