Service strategies and pricing based on heterogeneity of service values and waitingcosts in queuing system
Authors: Ma Baomei , Liu Sifeng , Liu Jian , Wang Yuning 
Published: August 2019

Purpose
This paper aims to study the corresponding optimal service strategies and pricing in the styled non-preemptive M/M/1 service systems from different objectives, which consider both heterogeneous waiting costs of customers and service values in customer segmentation.

Design/methodology/approach
In this paper, the authors consider two service situations where customers cannot leave the service system (i.e. monopoly service system) and customers can leave the service system freely (i.e. non-monopoly service system), respectively. The authors study the following four different perspectives that are revenue, social welfare, social cost and utility of customers. The authors first build up a new model, then propose the related objective functions. Further, the authors optimize the corresponding functions and achieve the optimal results. Later, the authors propose the corresponding optimal strategies. Finally, the authors use a practical numerical case to verify the proposed results.

Findings
The results of this paper indicates that the service provider should adopt classification services to gain the maximum revenue, the maximum social welfare and the minimum social costs by charging a priority fee in above two service systems. However, the service provider should cancel customer classification and keep regular customer only to obtain maximum utility. In the monopoly service system, both the optimal proportion priority customers and the revenue decrease with the increasing of the service rate, while in a non-monopoly service system, both of them are increasing with the service rate improving.

Originality/value
This paper first considers both heterogeneity of service values and waiting costs in queuing system, then the author set up a new model based on this assumption. Moreover, the authors draw the corresponding management insights based on the optimal results, which were unavailable before.
The adoption of green building practices in construction projects in Qatar: a preliminary study
Authors: Saleh Redhwan Mohammed , Al-Swidi Abdullah 
Published: August 2019

PurposeIt is widely known that carbon dioxide emissions and climate change are among the most critical global challenges. These issues were worsened partly by the continuous adoption of traditional non-green behaviors and practices in the construction sector. As both environmental and health-related practices continue to worsen, practitioners, researchers and government think tanks are taking a major shift to promote green building practices (GBP). The purpose of this paper is to examine and investigate the effects of several environment-related variables such as sustainable government support, environmental concern and green engagement in the adoption of GBP.Design/methodology/approachThe model of the study was developed based on the integration of the theory of planned behavior (TPB), value-belief-norm and cognition-affective behavior (CAB). The instrument used to capture these constructs was adapted from existing validated instruments. The data were collected from Qatar-based consultant and contractor engineers. Of the 877 questionnaires distributed, 378 were completed which yields a response rate of 43 percent. The collected data were analyzed by employing the PLS-SEM approach. First, the measurement model was examined to confirm the validity and reliability of the measures. Next, the structural model was analyzed to test the hypotheses of the study.FindingsThe results of the study showed that environment-related variables such as green engagement, sustainable government support and environmental concern have strong effects on GBP along with other TPB variables, namely, subjective norms and attitudes.Research limitations/implicationsAlthough the objectives of the study were achieved, there are still some limitations. First, this study yields a deemed suitable response rate. Second, since this research focused solely on the view of the contractors and consultants of the country’s engineering sector, it may have narrowed down the real scenario.Practical implicationsBesides the government providing awareness campaigns on the importance of GBP in reducing pollution, the government may also set some regulations to be followed by construction companies to reduce the negative impacts on the environment and regulations that could motivate the decision makers to increase the green construction projects and practices. In addition, the engineers still need some supports from green building authorities and government to motivate them toward GBP. Some incentives that could be offered by the government are financial allowances, funding and reduced governmental fees.Originality/valueThis study has a great theoretical value since it extended the TPB by incorporating some important environment-related variables to explain the adoption of GBP. In addition, from the practical perspective, this study provides useful insights for the practitioners and policy makers who are concerned about designing and planning environment-friendly strategies in the sector of construction.

Published: August 2019

Purpose
The purpose of this study is to evaluate the yield, physico-chemical and microbiological parameters during the shelf life of the Minas Frescal cheese hand-manufactured by family farms.

Design/methodology/approach
In the milk, analyses of total bacterial counts, somatic cell counts and centesimal composition were performed. The milk coagulation was analyzed, with different curd times (40, 80 and 120 min), with respect to the proximate composition, pH, titratable acidity, yield and microbiological counts. The means were compared using the Tukey test with a significance level of 5 per cent. The most probable number of microorganisms were also determined in water.

Findings
The results for milk quality were within the requirements established in Normative Instruction 62, except for total dry extract. It was found that curd time did not influence the protein and fat in dry matter contents; however, the ash content in cheese of 40 min of curd time (2.8 g/100g) is significantly higher (p = 0.02) than the values found for the other curd times. The same behavior was observed for moisture content (p = 0.04). The parameters determining the cheese quality were outside the standards for human consumption, but this result is directly related to the water conditions, which were outside of potability levels. To meet the requirements established in the legislation, dairy products must follow strict standards of quality hygiene, both the raw material (water, milk) and their employees who act directly in the process.

Originality/value
For the preparation of the Minas Frescal cheese, it takes several steps, from obtaining the milk to the product ready to be consumed, so the importance of doing this monitoring and evaluating its quality.
Helping behaviors convert negative affect into job satisfaction and creative performance
Authors: Chuang Yating , Chiang Hualing , Lin Anpan 
Published: August 2019

PurposeDrawing on mood regulation theories, the purpose of this paper is to examine the impact of employees’ coworker-helping behaviors (OCB-Is) on the relationships between prior negative affect and subsequent job satisfaction and creative performance. The authors hypothesize that employees’ work competence is a moderator of the relation between negative affect and OCB-Is.Design/methodology/approachData were collected by the experience sampling method of self-rating (twice per day) and coworker-rating (once per day) over two weeks by 120 administrative employees and their coworkers in a university; 743 available days were obtained.FindingsMultilevel modeling showed that self-rated negative affect during the morning was associated with coworker-rated OCB-Is during the afternoon; OCB-Is were positively associated with self-rated job satisfaction and coworker-rated creative performance during the afternoon; based on an indirect effect, OCB-Is mediated the relationships between negative affect and job satisfaction, and negative affect and creative performance; and employees with high-level work competences tended to engage in OCB-Is more than employees with low-level work competences when experiencing negative affect.Originality/valueThese findings suggest that OCB-Is create a positive reaction by converting negative affect into positive job satisfaction and creative performance and that employees’ work competence is the boundary condition.
Flexibility and innovation: moderator effects of cooperation and dynamism
Authors: Martínez-Sánchez Ángel , Vela-Jimenez Maria-Jose , Abella-Garces Silvia , Gorgemans Sophie 
Published: August 2019

Purpose
The purpose of this paper is to analyze simultaneously two moderator effects on a model of relationships between external human resource (HR) flexibility and innovation in a large sample of manufacturing firms.

Design/methodology/approach
The study sample consisted of 1,864 Spanish industrial firms in 2012 compiled from a large set of statements from the Survey of Business Strategies questionnaire. Logit and linear regressions tested the moderator effects of inter-organizational technology cooperation and environmental (market) dynamism in the relationship between external HR flexibility and innovation performance. To control for multicollinearity the Lance’s residual centering technique was used.

Findings
Process innovations seemed to be dependent on industry while innovative firms have developed a greater flexibility than non-innovative firms. Some moderator effects were found regarding inter-organizational cooperation while the market dynamism was negatively related to the measures of innovation with absence of moderator effects.

Research limitations/implications
Future studies should integrate more moderator effects that may influence the relationship between external HR flexibility and the firm’s innovation performance. The results regarding the influences of external flexibility on innovation have to be differentiated as inter-organizational technological cooperation compensated the influence of external workplace flexibility on innovation.

Practical implications
Managers should use a right mix of external flexibility measures according to the inter-organizational cooperation but regardless the level of environmental dynamism.

Originality/value
This paper is original in the sense that it studies the relationship between external HR flexibility and innovation with the simultaneous moderator effect of inter-organizational technology cooperation and market dynamism. The value of the paper lies in the discussion of interrelated moderator effects in order to propose adequate strategies to develop external HR flexibility.
Husserl’s epoche and the way of the sword: exploring pathways into phenomenological inquiry
Authors: Roberts Bradley Edward 
Published: August 2019

Purpose
Phenomenology is widely recognised for its power to generate nuanced understanding of lived experience and human existence. However, phenomenology is often made inaccessible to prospective researchers due to its specialised nomenclature and dense philosophical underpinnings. This paper explores the value of the researcher’s lived experience as a pathway into phenomenological inquiry. The purpose of this paper is to improve the accessibility of phenomenology as a method for qualitative analysis. It achieves this by aligning Husserl’s concept of phenomenological epoche, or bracketing of preconceptions, and the author’s lived experience as a practitioner of kendo, or Japanese fencing.

Design/methodology/approach
The paper employs the narrative vignette as a means of illuminating the intersections between kendo practice and the application of phenomenological epoche as it applies to the understanding of embodied sensemaking. Reflections on the narrative vignette identified a suite of techniques from kendo practice that were applied to a phenomenological approach for critical incident interviews. These techniques were then applied to 30 critical incident, semi-structured interviews as part of a PhD research project into embodied sensemaking.

Findings
The results from these interviews suggest that the kendo-derived techniques were effective in generating thick narratives from participants during semi-structured interviews. Examination of the results provided insights into the linkage between phenomenology as a continental philosophy and eastern perspectives such as those found within the Zen traditions and other aesthetic practices.

Originality/value
This research suggests that lived experience such as kendo practice can provide a ready-to-hand pathway to phenomenological inquiry.

Authors: Ahmed Waqar , Najmi Arsalan , Arif Muhammad , Younus Muhammad 
Published: August 2019

PurposeEnvironmental concerns are rapidly increasing in the industries across the world. They are a more serious issue, especially, in the developing countries due to the prevalence of old practices and outdated technology. The purpose of this paper is to understand the role of institutional pressure and environmental orientation of the firm in adopting green supply chain management (GSCM) practices, and thereon the effect of GSCM on the firm’s performance.Design/methodology/approachBy employing survey methodology using purposive sampling technique, the data were collected from 229 respondents who were working as supply chain management professionals in various manufacturing firms. The hypotheses were tested through partial least square structural equation modeling (PLS-SEM).FindingsThe findings reveal that both institutional pressures and environmental orientation significantly impact GSCM practices. The result further shows that GSCM practices have a positive effect on the environmental and economic performance as well as customer effectiveness.Originality/valueIndustries in the developing economies like Pakistan are reluctant to implement GSCM practices due to the perception of ambiguous financial implications. This study signifies that institutional pressures act as an effective driving force for change management and compliance.

Published: August 2019

PurposeThe purpose of this paper is to examine the social impact of an initiative (Hockey FIT) aimed at improving the health and well-being of sport fans and their community.Design/methodology/approachFans (n=80) participated in 12 weekly health promotion sessions hosted in local hockey club facilities. Objective health measurements, diet and physical activity levels of fans were measured at baseline, 12 weeks and 12 months, to determine the intermediate, long-term, individual and community impact. Furthermore, one-on-one interviews with 28 program participants were conducted to further understand the program’s social impact.FindingsThe intermediate impact was noticed as improvements in weight loss, body mass index, waist circumference, systolic blood pressure (BP), steps per day, healthful eating, self-reported overall health and fatty food scores at 12 weeks. The long-term individual impact of Hockey FIT was realized as participants maintained or continued to improve their weight loss, waist circumference, healthful eating, systolic BP and diastolic BP 12 months after the program had been offered. The program was also reported to increase family bonding time and improved the diet, daily physical activity, and general awareness of health promotion programs and components for friends, family members and coworkers.Originality/valueThe positive health-related results from this study contradict prior research that has suggested there is minimal evidence of any substantial contributions from social programs in sport. Through a collective approach to corporate social responsibility, this research demonstrates the ability for sport organizations to contribute to meaningful social change and the positive role that they play within the community.

MicroRNA‐198‐5p inhibits the migration and invasion of non‐small lung cancer cells by targeting fucosyltransferase 8
Authors: Wang Siyao , Zhang Xin , Yang Chunlu , Xu Shun 
Published: August 2019

AbstractMicroRNA‐198‐5p (miR‐198‐5p) displays crucial roles in various cancers including non‐small cell lung cancer (NSCLC), but the underlying molecular mechanisms remain unclear. Fucosyltransferase 8 (FUT8) is associated with tumour metastasis and prognosis. In this study, we explored the expression of miR‐198‐5p and FUT8 in NSCLC patients. Results showed that miR‐198‐5p was under‐expressed in NSCLC tissues and was negatively correlated with tumour size, lymph node metastasis and tumour‐node‐metastasis stage, while FUT8 expression was highly upregulated. Next, we altered miR‐198‐5p expression using the mimic or inhibitor in the functional study. Results showed that miR‐198‐5p overexpression could inhibit the migration, invasion and epithelial‐to‐mesenchymal transition (EMT) of NSCLC cells; reversely, suppression of miR‐198‐5p enhanced cell migration, invasion and EMT. In vivo, miR‐198‐5p overexpression inhibited the formation of mouse lung and liver metastasis. Luciferase reporter, real‐time PCR and western blot assays showed that miR‐198‐5p could directly target FUT8 and regulate FUT8 expression. Further, FUT8 overexpression reversed the effect of miR‐198‐5p overexpression on the migration, invasion and EMT of NSCLC cells. Taken together, miR‐198‐5p functions as a tumour suppressor by targeting FUT8 in NSCLC. MiR‐198‐5p may be developed as a new diagnostic biomarker and therapeutic target for lung cancer.
Dual functions of AreA, a GATA transcription factor, on influencing ganoderic acid biosynthesis in Ganoderma lucidum
Authors: Zhu Jing , Sun Zehua , Shi Dengke , Song Shuqi , Lian Lingdan , Shi Liang , Ren Ang , Yu Hanshou , Zhao Mingwen 
Published: August 2019

SummaryNitrogen metabolism repression (NMR) has been well studied in filamentous fungi, but the molecular mechanism of its effects on fungal secondary metabolism has been generally unexplored. Ganoderic acid (GA) biosynthesis in Ganoderma lucidum differs between ammonia and nitrate nitrogen sources. To explain the functions of NMR in secondary metabolism, AreA, which is a core transcription factor of NMR, was characterized in G. lucidum. The transcription level of AreA was dramatically increased (approximately 4.5‐folds), with the nitrate as the sole nitrogen source, compared with that with ammonia as the source. In addition, the expression of related genes involved in NMR was changed (upregulated of MeaB and downregulated of Nmr and GlnA) when AreA was knockdown. Yeast one‐hybrid and electrophoretic mobility shift assay results showed that AreA could directly bind to the promoter of fps (encoding farnesyl‐diphosphate synthase) to activate its expression. However, GA biosynthesis was increased (27% in the ammonia source and 77% in the nitrate source) in AreAi mutant strains versus that in control strains. These results showed that another important factor must participate in regulating GA biosynthesis other than the direct activation of AreA. Furthermore, we found that the content of nitric oxide (NO) was increased approximately 2.7‐folds in the nitrate source compared with that in the ammonia. By adding the NO donor (SNP) or scavenger (cPTIO) and using NR‐silenced or NR‐overexpressed strains, we found that there was a negative correlation between the NO contents and GA biosynthesis. NO generated by nitrate reductase (NR) during the nitrogen utilization burst and could negatively influence GA biosynthesis. As a global transcription factor, AreA could also regulate the expression of NR. Our studies provide novel insight into the dual functions of AreA in GA biosynthesis during nitrogen assimilation.
Hamburg's Spaces of Danger: Race, Violence and Memory in a Contemporary Global City
Authors: MacFarlane Key , Mitchell Katharyne 
Published: August 2019

AbstractGermany today is experiencing the strongest upsurge of right‐wing populism since the second world war, most notably with the rise of Pegida and Alternative für Deutschland. Yet wealthy global cities like Hamburg continue to present themselves as the gatekeepers of liberal progress and cosmopolitan openness. This article argues that Hamburg's urban boosterism relies on, while simultaneously obscuring, the same structures of racial violence that embolden reactionary movements. Drawing on the work of Walter Benjamin and Allan Pred, we present an archaeology of Hamburg's landscape, uncovering some of its ‘spaces of danger’—sites layered with histories of violence, many of which lie buried and forgotten. We find that these spaces, when they become visible, threaten to undermine Hamburg's cosmopolitan narrative. They must, as a result, be continually erased or downplayed in order to secure the city as an attractive site for capital investment. To illustrate this argument, we give three historical examples: Hamburg's role in the Hanseatic League during the medieval and early modern period; the city under the Nazi regime; and the recent treatment of Black African refugees. The article's main contribution is to better situate issues of historical landscape, collective memory and racialized violence within the political economy of today's global city.
