Sleep quality among industrial workers: related factors and impact
Authors: Songkham Wanpen , Deeluea Jirawan , Suksatit Benjamas , Chaiard Jindarat 
Published: November 2018

Purpose
The purpose of this paper is to explore the prevalence and determinants of poor sleep quality among industrial workers in Thailand. Additionally, the authors assess the risk of work-related injuries associated with poor sleep quality.

Design/methodology/approach
A descriptive correlational research was implemented. A total of 472 workers from the northern region of Thailand contributed to this study. Sleep quality was assessed by the Thai version of the Pittsburgh Sleep Quality Index (Thai-PSQI). The score of more than five indicated poor sleep quality. Participants completed self-administered demographic, work characteristics and work-related injury questionnaires. Data were analyzed by applying descriptive and logistic regression statistical techniques.

Findings
More than one-third of the workers had reported poor sleep quality. Results from multivariable logistic regression analysis yielded male gender (OR = 2.74, 95% CI 1.46–5.17), alcohol drinking (OR=2.1, 95% CI 1.24–3.35), pain (OR=2.05, 95% CI 1.32–3.17) and rotating shift work (OR=1.94, 95% CI 1.23–3.05) increased the risk of poor sleep quality. Furthermore, poor sleep quality was statistically significantly associated with the risk of work-related injuries (OR = 3.98, 95% CI = 2.39–6.66).

Originality/value
Findings of this study indicate that the prevalence of poor sleep quality is high among industrial workers. Work characteristics and health behaviors were associated with poor sleep quality which increases the risk of work-related injuries. Modification of work environment and personal life style choices can improve quality of sleep among workers and consequently lower incidence of work-related injuries.
Multi-objective particle swarm optimisation approach for production-inventory control systems
Authors: AL-Khazraji Huthaifa , Cole Colin , Guo William 
Published: November 2018

Purpose
This paper aims to optimise the dynamic performance of production–inventory control systems in terms of minimisation variance ratio between the order rate and the consumption, and minimisation the integral of absolute error between the actual and the target level of inventory by incorporating the Pareto optimality into particle swarm optimisation (PSO).

Design/method/approach
The production–inventory control system is modelled and optimised via control theory and simulations. The dynamics of a production–inventory control system are modelled through continuous time differential equations and Laplace transformations. The simulation design is conducted by using the state–space model of the system. The results of multi-objective particle swarm optimisation (MOPSO) are compared with published results obtained from weighted genetic algorithm (WGA) optimisation.

Findings
The results obtained from the MOPSO optimisation process ensure that the performance is systematically better than the WGA in terms of reducing the order variability (bullwhip effect) and improving the inventory responsiveness (customer service level) under the same operational conditions.

Research limitations/implications
This research is limited to optimising the dynamics of a single product, single-retailer single-manufacturer process with zero desired inventory level.

Originality/value
PSO is widely used and popular in many industrial applications. This research shows a unique application of PSO in optimising the dynamic performance of production–inventory control systems.
Transformational leadership and four-dimensional commitment
Authors: Islam Talat , Tariq Jawad , Usman Bushra 
Published: November 2018

Purpose
The purpose of this paper is to investigate the mechanism between transformational leadership (TL) and organizational commitment (OC) using job characteristics as a mediator and participative and directive leadership (DL) as moderator.

Design/methodology/approach
The authors used a questionnaire-based survey to collect data from 563 employees working in the banking industry.

Findings
The data were analyzed using structural equation modeling. The findings confirmed the mediating role of job characteristics and moderating role of both participative and DL styles between TL and OC.

Research limitations/implications
The data for this study were collected at one point of time and it has implications for the policymakers and bankers.

Originality/value
The study is novel as it highlights the importance of job characteristics, participative and DL styles in understanding the relationship between TL and OC.
Lessons for commissioning and health outcomes from Her Majesty’s Prison Birmingham
Authors: Cassidy Jan , Caan Woody 
Published: November 2018

Purpose
This study of HMP Birmingham was part of a much larger investigation of health needs assessment (HNA), in the context of a new “HNA Toolkit” developed by Public Health England for use in the prison service. The paper aims to discuss this issue.

Design/methodology/approach
In 2015, details of prison healthcare in HMP Birmingham had figured in the authors’ analysis of documents. In 2018, a crisis in Birmingham typified problems developing more widely in England and Wales. Was the crisis predictable from the initial HNA?

Findings
Recommendations embodied in the 2015 HNA were not acted upon; the eventual problems that combined to overwhelm the running of HMP Birmingham were predictable.

Originality/value
Lessons from this case study could inform more coherent commissioning of prison health services. This in turn could promote timely developments for improved health and morale in the prison, amongst prisoners and staff. Longer term, this might help to avoid future crises.
A review of value drivers in service settings
Authors: Ruiz-Molina Maria-Eugenia , Gallarza Martina , Gil-Saura Irene 
Published: November 2018

Purpose
Perceived value and customer loyalty have been studied jointly in most of services literature but mainly through SEM models. This paper aims to draw on the literature on the multidimensional richness of perceived value, to adopt a segmentation approach and explore segments of loyal consumers towards the service provider based on their value perceptions.

Design/methodology/approach
A survey was conducted among 460 Spanish consumers interviewed at the store exit of seven retail chains in two sectors (grocery and home furnishing). A CHAID analysis was performed on loyalty responses, through nine value dimensions (efficiency, service quality, product quality, emotional value, value for money, social value, aesthetic value, escapism and ethics).

Findings
Results show the existence of different groups of loyal customers based on the nine value types. Efficiency is prioritised by the most loyal customers in grocery but not for home furnishing. Emotional value and aesthetics, along with product quality determine the most loyal segments.

Practical implications
Retailers should focus on enhancing those value dimensions that better explain customer loyalty towards retail stores in their area of specialisation, combining not only tangible and intangible elements but also functional and emotional elements.

Originality/value
The paper adds to the prolific research on perceived value in services with a diachronic graphical review of value dimensions in retailing; furthermore, the range of value dimensions studied here is wider than most of previous works using dimensions of value in services.
Event news detection and citizens community structure for disaster management in social networks
Authors: Toujani Radhia , Akaichi Jalel 
Published: November 2018

Purpose
Nowadays, the event detection is so important in gathering news from social media. Indeed, it is widely employed by journalists to generate early alerts of reported stories. In order to incorporate available data on social media into a news story, journalists must manually process, compile and verify the news content within a very short time span. Despite its utility and importance, this process is time-consuming and labor-intensive for media organizations. Because of the afore-mentioned reason and as social media provides an essential source of data used as a support for professional journalists, the purpose of this paper is to propose the citizen clustering technique which allows the community of journalists and media professionals to document news during crises.

Design/methodology/approach
The authors develop, in this study, an approach for natural hazard events news detection and danger citizen’ groups clustering based on three major steps. In the first stage, the authors present a pipeline of several natural language processing tasks: event trigger detection, applied to recuperate potential event triggers; named entity recognition, used for the detection and recognition of event participants related to the extracted event triggers; and, ultimately, a dependency analysis between all the extracted data. Analyzing the ambiguity and the vagueness of similarity of news plays a key role in event detection. This issue was ignored in traditional event detection techniques. To this end, in the second step of our approach, the authors apply fuzzy sets techniques on these extracted events to enhance the clustering quality and remove the vagueness of the extracted information. Then, the defined degree of citizens’ danger is injected as input to the introduced citizens clustering method in order to detect citizens’ communities with close disaster degrees.

Findings
Empirical results indicate that homogeneous and compact citizen’ clusters can be detected using the suggested event detection method. It can also be observed that event news can be analyzed efficiently using the fuzzy theory. In addition, the proposed visualization process plays a crucial role in data journalism, as it is used to analyze event news, as well as in the final presentation of detected danger citizens’ clusters.

Originality/value
The introduced citizens clustering method is profitable for journalists and editors to better judge the veracity of social media content, navigate the overwhelming, identify eyewitnesses and contextualize the event. The empirical analysis results illustrate the efficiency of the developed method for both real and artificial networks.
How to establish a good government? Lessons from Lee Kuan Yew in Singapore and Deng Xiaoping in China
Authors: Choi Franky K.H. 
Published: November 2018

Purpose
Outside the US and Europe, to establish a good government requires more than Western-style democracy. Adopting universal suffrage fully from the Western model is no longer a panacea to reach the ultimate goal of good governance in the East, i.e., to keep promoting socio-economic renovation can be noted as a prerequisite to have further meaningful political advancement in an Asian polity. The purpose of this paper is to explain how to establish a good but authoritarian government in the East.

Design/methodology/approach
Given the good of comparative historical analysis, Lee Kuan Yew in Singapore and Deng Xiaoping in China are selected as both cases for “method of agreement.” Further including “argument based on the contrary” to form a context for macro-historical analysis, this paper outlines two characteristics of the duo’s authoritarian leadership, namely, Ideologies and Policy-making; and Political Modernization, and hence provides a more balanced reevaluation of their governance.

Findings
Apart from noting how these two Asian giants more or less contributed to their good but authoritarian governments for long in the twentieth century, such a word of authoritarianism to the duo was quite positive to help legitimize their governance, which was far different from many negative views of the Western world.

Originality/value
As theories put forward by Western academics could not entirely justify modernization among Asian societies in the twentieth century, this paper attempts to answer one question: Does the meaning of authoritarianism remain unchanged in the discourse of the East and the West?
A case study of the critical success factors for organizational change of a public listed corporation
Authors: Li Earnest 
Published: November 2018

PurposeThe purpose of this paper is to explain how an organization can achieve successful change implementation with Kotter’s eight-step organizational change model and 3-H (heart–head–hand) theory.Design/methodology/approachWith the case study approach, the author recollects his career experience in Hong Kong Broadband Network Limited from 2007 to 2011 to find out why and how the top management can balance 3-H factor to bridge the “knowing” and “doing” gap to engage right talents and motivate them to achieve peak performance and company goal.FindingsTo create talent culture, the company implemented two policies including Mini-CEO management and Talent Engagement Department. The former is a vertical management model to empower and enable department heads. The latter is a way to change the role of human resources department from passive to proactive.Originality/valueThe implications of this case study are to encourage public and private organizations to rethink the factors including talent development and empowerment that can have a positive impact on innovative work behavior. Moreover, organizations can rediscover the value of “unique” talent culture as a sustainable competitive advantage.
Impact of financial leverage on profitability of listed manufacturing firms in China
Authors: Dalci Ilhan 
Published: November 2018

PurposeThe purpose of the study is to explore how financial leverage influences profitability of 1,503 listed manufacturing firms in China.Design/methodology/approachThe sample of the study is composed of the listed manufacturing firms in China. For the manufacturing firms, the annual financial information from 2008 to 2016 is obtained from the ORBIS database. In this study, initially a simultaneous equation approach is used to control for potential endogeneity. Then, additional regression analyses are conducted with panel data over the period of 2008-2016 using OLS, Fixed-effects, First-difference, Random-effects and Arellano and Bond’s (1991) two-step Generalized Method of Moments (GMM) methods.FindingsThe results reveal that the impact of leverage on profitability is inverted U-shaped. In this inverted U-shaped relationship, the positive impact of financial leverage on profitability could be attributed to tax shield, whereas the negative impact might be because of bankruptcy cost, financial distress, severe agency problems and information asymmetry that the listed Chinese firms suffer from because of some institutional characteristics of China.Research limitations/implicationsFirst, this study focuses on only listed manufacturing firms in China. Second, ownership types are not taken into account in this study.Practical implicationsFirst, the Chinese government should direct its efforts toward developing the bond markets and promoting alternative privately owned loan creditors to state-owned banks. Parallel to this, the transformation process toward market economy should be accelerated to facilitate the privatization of state-owned enterprises (SOEs). In addition to this, development of the bond market and privatization of SOEs will also mitigate the agency conflict between creditors and managers and between shareholders and managers.Originality/valueTo the best of the author’s knowledge, this is the first study which investigates the impact of capital structure on profitability of the listed firms in China.
“Decent work” in the ready-made garment sector in Bangladesh
Authors: Khan Sardana Islam , Bartram Timothy , Cavanagh Jillian , Hossain Md Sajjad , Akter Silvia 
Published: November 2018

PurposeThe purpose of this paper is to examine the perspectives of 26 business owners, managers and supervisors on “decent work” (DW) in the ready-made garment (RMG) sector in Bangladesh.Design/methodology/approachThe qualitative study draws on a framework of ethical human resource management and situated moral agency to establish the ways in which RMG workers are afforded DW. This study uses semi-structured interviews to assess the prospect of DW through applying the ILO’s four-pillar framework of DW.FindingsFindings indicate there is a concern among owners and managers of the need to reconcile internal and external pressures to maintain and improve DW. It is evident that ethical practices and moral agency are not self-initiated but in response to mounting political and legal pressures and those of external stakeholders. Employers favour the concept of workers’ participation committees as one means to communicate and negotiate with workers rather than recognise trade unions.Research limitations/implicationsThe research is limited to six organisations in the RMG sector in Bangladesh, but there are implications for all RMG sector organisations to promote reform and DW for all workers.Practical implicationsDW necessitates major national and international stakeholders to negotiate and cooperate to ensure the long-term competitiveness and survival of the Bangladeshi RMG sector.Originality/valueThe study calls for reform in a developing country where many workers are denied DW.
Typologies of internationalisation pathways of SMEs: what is new?
Authors: Coudounaris Dafnis N. 
Published: November 2018

Purpose
This study aims to examine internationalisation pathways of small and medium enterprises (SMEs) based on a sample from Manchester, UK, and it provides an exercise theory testing of the Uppsala model with data from SMEs from Manchester. It investigates the existence of new internationalisation pathways and the parallel use of four dimensions, namely, export intensity, export destination, time dimension and number of export markets.

Design/methodology/approach
The suggested model of international pathways is developed based on a survey of 110 firms located in the Greater Manchester area. The study of the population was based on a stratified sample of firms included in the KOMPASS directory in the Greater Manchester area. t-Test analysis was performed on combinations of the six pathways.

Findings
The results reveal that SMEs follow a pattern of internationalisation pathways consisting of non-exporters, traditional small exporters, traditional medium exporters, accelerated medium exporters, born globals and declining exporters. The paper concludes that the Uppsala model does not apply in this study.

Originality/value
There is evidence of a new pathway, i.e. accelerated medium exporters and the CEOs of Manchester SMEs, and governmental authorities in the UK should consider targeting this group or developing appropriate export promotion programmes.
Periphytic algae decouple fungal activity from leaf litter decomposition via negative priming

Published: November 2018

Abstract

Well‐documented in terrestrial settings, priming effects describe stimulated heterotrophic microbial activity and decomposition of recalcitrant carbon by additions of labile carbon. In aquatic settings, algae produce labile exudates which may elicit priming during organic matter decomposition, yet the directions and mechanisms of aquatic priming effects remain poorly tested.

We tested algal‐induced priming during decomposition of two leaf species of contrasting recalcitrance, Liriodendron tulipifera and Quercus nigra, in experimental streams under light or dark conditions. We measured litter‐associated algal, bacterial, and fungal biomass and activity, stoichiometry, and litter decomposition rates over 43 days.

Light increased algal biomass and production rates, in turn increasing bacterial abundance 141%–733% and fungal production rates 20%–157%. Incubations with a photosynthesis inhibitor established that algal activity directly stimulated fungal production rates in the short term.

Algal‐stimulated fungal production rates on both leaf species were not coupled to long‐term increases in fungal biomass accrual or litter decomposition rates, which were 154%–157% and 164%–455% greater in the dark, respectively. The similar patterns on fast‐ vs. slow‐decomposing L. tulipifera and Q. nigra, respectively, indicated that substrate recalcitrance may not mediate priming strength or direction.

In this example of negative priming, periphytic algae decoupled fungal activity from decomposition, likely by providing labile carbon invested towards greater fungal growth and reproduction instead of recalcitrant carbon degradation. If common, algal‐induced negative priming could stimulate heterotrophy reliant on labile carbon yet suppress decomposition of recalcitrant carbon, modifying energy and nutrients available to upper trophic levels and enhancing organic carbon storage or export in well‐lit aquatic habitats.

Published: November 2018

AbstractBackgroundTo date, the immediate effects of a semi‐occluded vocal tract (SOVT) configuration have been thoroughly demonstrated. However, it is not yet sufficiently confirmed whether a therapy programme (i.e. longer than one session) using SOVT exercises leads to an enhanced phonation and improved vocal quality.AimsThe aim of this study was to investigate the effect of three SOVT therapy programmes: lip trill, water‐resistance therapy (WRT) and straw phonation, on the vocal quality, vocal capacities, psychosocial impact and vocal tract discomfort of patients with dysphonia.Methods & ProceduresA blocked‐randomized sham‐controlled trial was used. Thirty‐five patients with dysphonia (mean age = 21 years; 33 women, two men) were assigned to either a lip trill group, a WRT group, a straw phonation group or a control group using blocked randomization. The lip trill, WRT and straw phonation groups practised their respective SOVT exercise across 3 weeks, whereas the control group received a sham treatment across the same time span. A multidimensional voice assessment consisting of both objective (multiparametric indices: Dysphonia Severity Index (DSI), Acoustic Voice Quality Index (AVQI)) and subjective (subject's self‐report, auditory–perceptual evaluation) vocal outcomes was performed by a blinded assessor pre‐ and post‐therapy.Outcomes & ResultsLip trill and straw phonation therapy led to a significant improvement in DSI. Auditory–perceptual grade and roughness significantly decreased after straw phonation. Lip trill and WRT both led to a significant decrease in Voice Handicap Index. Subjects reported a better self‐perceived vocal quality and a more comfortable voice production after WRT. No changes were found after the sham treatment in the control group.Conclusions & ImplicationsResults suggest that SOVT therapy programmes including lip trill or straw phonation can improve the objective vocal quality in patients with dysphonia. Auditory–perceptual improvements were found after straw phonation therapy, whereas psychosocial improvements were found after lip trill and WRT. Patients seem to experience more comfort and a better self‐perceived vocal quality after WRT. This study supports the use of the three SOVT therapy programmes in clinical practice. They all had a positive impact on one or more outcomes of the multidimensional voice assessment. Strikingly, vocal quality outcomes were not in line with the subject's opinion. Larger‐scale investigation is needed to support these preliminary findings.
