A novel image super-resolution reconstruction algorithm based on improved GANs and gradient penalty
Authors: Liu Shuangshuang , Li Xiaoling 
Published: August 2019

Purpose
Conventional image super-resolution reconstruction by the conventional deep learning architectures suffers from the problems of hard training and gradient disappearing. In order to solve such problems, the purpose of this paper is to propose a novel image super-resolution algorithm based on improved generative adversarial networks (GANs) with Wasserstein distance and gradient penalty.

Design/methodology/approach
The proposed algorithm first introduces the conventional GANs architecture, the Wasserstein distance and the gradient penalty for the task of image super-resolution reconstruction (SRWGANs-GP). In addition, a novel perceptual loss function is designed for the SRWGANs-GP to meet the task of image super-resolution reconstruction. The content loss is extracted from the deep model’s feature maps, and such features are introduced to calculate mean square error (MSE) for the loss calculation of generators.

Findings
To validate the effectiveness and feasibility of the proposed algorithm, a lot of compared experiments are applied on three common data sets, i.e. Set5, Set14 and BSD100. Experimental results have shown that the proposed SRWGANs-GP architecture has a stable error gradient and iteratively convergence. Compared with the baseline deep models, the proposed GANs models have a significant improvement on performance and efficiency for image super-resolution reconstruction. The MSE calculated by the deep model’s feature maps gives more advantages for constructing contour and texture.

Originality/value
Compared with the state-of-the-art algorithms, the proposed algorithm obtains a better performance on image super-resolution and better reconstruction results on contour and texture.

Authors: Peacock Shelley , Burles Meridith , Hodson Alexandra , Kumaran Maha , MacRae Rhoda , Peternelj-Taylor Cindy , Holtslander Lorraine 
Published: August 2019

PurposeThe number of prisoners over 55 years is increasing and many are at risk of developing dementia. This has generated new responsibilities for prisons to provide health and social care for older persons. The purpose of this paper is to synthesize the existing research literature regarding the phenomenon of the health and social care needs of older persons living with dementia in correctional settings.Design/methodology/approachUsing an integrative review method based on Whittemore and Knafl, the inclusion criteria for the review are: articles written in English; a focus on some form of dementia and/or older persons with discussion of dementia; to be set in a correctional context (correctional facility, prison and jail); be derived from a published peer-reviewed journal or unpublished dissertation/thesis; and be a qualitative, quantitative or mixed methods study. Based on those criteria, a search strategy was developed and executed by a health sciences librarian in the following databases: Medline, CINAHL, Embase, PsychINFO, Proquest Nursing and Allied Health and Web of Science; searches were completed up to April 2019. After data were extracted from included studies, synthesis of findings involved an iterative process where thematic analysis was facilitated by Braun and Clarke’s approach.FindingsEight studies met the inclusion criteria. Key findings of the eight studies include recognition of dementia as a concern for correctional populations, dementia-related screening and programming for older persons and recommendations for improved screening and care practices. Most significant is the paucity of research available on this topic. Implications for research are discussed.Originality/valueThis paper identified and synthesizes the limited existing international research on the health and social care needs of older persons with dementia living in correctional settings. Although existing research is scant, this review highlights the need for increased awareness of dementia as a concern among older persons living in correctional settings. As well, the review findings emphasize that enhanced screening and interventions, particularly tailored approaches, are imperative to support those living with dementia in correctional settings.
Posttraumatic stress, panic disorder, violence, and recidivism among local jail detainees
Authors: Combs Elizabeth , Guston Kaitlin , Kopak Albert , Raggio Alyssa , Hoffmann Norman G. 
Published: August 2019

Purpose
Most research on posttraumatic stress disorder (PTSD) and offending has been conducted with special populations (e.g. veterans and female inmates) and generally overlooks the additive effect of panic disorder (PD) in offending patterns. The purpose of this paper is to assess the prevalence of PTSD and PD among jail inmates, while simultaneously examining the relationships between these disorders, offending types and frequency.

Design/methodology/approach
A random sample of adults recently booked into a local county jail participated in the Comprehensive Addictions and Psychological Evaluation-5 (CAAPE-5), a structured psychological assessment. The study sample was comprised of 200 male and 83 female inmates.

Findings
Indications of PTSD were observed among 44.0 percent of male inmates and 57.8 percent of female inmates. Most male inmates (78.4 percent) with positive PTSD indications also met criteria for PD, with a similar proportion (78.1 percent) of female inmates also meeting criteria for both. The combination of PTSD and PD was not associated with offending frequency, but inmates presenting indications of both PTSD and PD were more likely to be charged with a violent offense relative to those with only PTSD.

Practical implications
Inmates with PTSD who also have panic attacks may have a more severe condition with possible implications for other risks. Observations of these conditions among adults recently booked into local jails should coincide with each other.

Originality/value
Few studies have examined mental health conditions among local jail detainees, despite the ever-present need to address them. The current study considers this important population and investigates the prevalence of co-occurring conditions.
Effects of green human resource management: testing a moderated mediation model
Authors: Chaudhary Richa 
Published: August 2019

PurposeThe purpose of this paper is to examine organizational attractiveness as a mechanism through which adoption of green human resource management (GHRM) practices affects potential employees’ intent to pursue career in an organization. Specifically, an integrative moderated mediation model with employees’ personal environmental orientation as moderator of the above-stated relationship was proposed.Design/methodology/approachThe sample comprised 172 final-year engineering students registered in a four-year undergraduate program in one of the top higher education institutes in India. SPSS 24 was used to test the moderated mediation model with the help of hierarchical regression procedures.FindingsResults provided support for the moderated mediation model in which the indirect effect of GHRM on job pursuit intention through organizational attractiveness was moderated by environmental orientation of prospective applicants.Practical implicationsResults highlight the potential of GHRM in turning the organizations into talent magnets. This knowledge will motivate practitioners to effectively integrate GHRM with human resource policies, practices and employee initiatives for attracting quality applicants.Originality/valueThis research by presenting the positive outcomes of GHRM for the organizations contributes to scant academic literature on sustainable human resource management which is deficient with regard to knowledge around its consequences.
Effect of MWCNTs/Talc powder nanoparticles on the tribological and thermal conductivity performance of calcium grease
Authors: Mobasher Ahmed , Khalil Alaa , Khashaba Medhat , Osman Tarek 
Published: August 2019

Purpose
The purpose of this paper is to evaluate the influence of nanoparticles as an additive on the tribological properties of calcium grease.

Design/methodology/approach
The nano additives in this research are with different concentration of multi carbon nanotubes (MWCNTs) and Talc powder (1, 2, 3, 3 and 5 per cent). The ratio of MWCNTs to Talc powder is 1:1. The tribological properties of hyper MWCNTs/Talc powder to calcium grease were evaluated using a pin-on-disk wear testing. The results show that the nano additives MWCNTs/Talc to calcium grease exhibit good performance in anti-wear and friction reduction. The action mechanism was estimated through analysis of the worm surface with x-ray diffraction and transmission electron microscope.

Findings
The result indicates that boundary film mainly composed of MWCNT and Talc powder, and other organic compound was formed on the worm surface during the friction test. In addition, the wear rate and coefficient of friction of nanogreases have shown excellent improvement about 80.62 and 63.44 per cent, respectively, at 4 Wt.% of MWCNTs/Talc powder. Moreover, the thermal conductivity of nanogrease increased about 51.72 per cent.

Originality/value
This study describes the inexpensive and simple fabrication of nanogrease for improving properties of lubricants, which improve power efficiency and extend lifetimes of mechanical equipment.
Electricity consumption and GDP nexus in Bangladesh: a time series investigation
Authors: Dey Sima Rani , Tareque Mohammed 
Published: August 2019

Purpose
The purpose of this paper is to assess the empirical cointegration, long-run and short-run dynamics as well as causal relationship between electricity consumption and real GDP in Bangladesh for the period of 1971‒2014.

Design/methodology/approach
Autoregressive Distributed lag (ARDL) “Bound Test” approach is employed for the investigation in this study.

Findings
Both short-run and long-run coefficients are providing strong evidence of having positive significant association between electricity consumption and GDP. Our long-run results remain robust to different measurements and estimators as well. The study reveals the unidirectional causal flow running from per capita electricity consumption to per capita real GDP in the short run. The study result also yields strong evidence of bidirectional causal relationship between per capita electricity consumption and per capita real GDP in the long run with feedback. It is suggested that both electricity generation and conservation policy will be effective for Bangladesh economy.

Originality/value
In prior studies, lack of causality between electricity consumption and GDP is due to the omitted variables. Combined effects of public spending and trade openness on GDP and electricity consumption are also considerable.
Three effects of stock repurchase on rival firms in Vietnam
Authors: Hoa Nguyen Hong Thi , Nguyen Dat Tien , Pham Anh Hong 
Published: August 2019

Purpose
The purpose of this paper is to examine the effects of share repurchase announcements on the stock price of rival firms in the same industry in Vietnam during 2010–2017.

Design/methodology/approach
Both event study and t-test are employed to test the effects of share repurchase announcements on rival firms. In addition, cross-sectional analysis by ordinary least square regression is also applied for investigating the heterogeneous effects due to information transfer.

Findings
The finding shows that stock repurchase announcements result in a positive and significant valuation effect for both announcing firms and rival firms in Vietnam. Furthermore, the degree of signal to the industry is conditional on the degree of signal about the announcing firms as a contagious effect. Intra-industry effects are more favorable when profit performance of rival firms is good and when leverage of rival firms is low.

Practical implications
Rival firms can seize opportunities surrounding share repurchase announcements in the same industry in Vietnam. However, due to firm characteristics, intra-industry effects of stock repurchases differ among industries.

Originality/value
By examining different methods, the paper attributes valuable results to investigate the stock price behavior of rival firms in the same industry when firms announce stock repurchase in Vietnam.
Independent directors and corporate investment: evidence from an emerging market
Authors: Tran Quoc Trung 
Published: August 2019

Purpose
The purpose of this paper is to examine whether independent directors reduce corporate overinvestment and improve investment efficiency in an emerging market.

Design/methodology/approach
First, the author developed a research model in which corporate investment is a function of Tobin’s Q, the proportion of independent directors in the board and an interaction between them. Second, the author divided the full sample into groups of firms with a low- and high-financial constraint to compare the effects of independent directors between financially unconstrained and constrained firms.

Findings
With a full sample of 1,281 observations collected from 193 firms listed in Ho Chi Minh Stock Exchange during the period from 2009 to 2017, the author find that the proportion of independent directors is negatively related to firm investment but its interactive term with Tobin’s Q is positively related to corporate investment. These findings imply that independent directors can help firms reduce overinvestment and improve investment efficiency. Moreover, the research findings indicate that these effects of independent directors are stronger for financially constrained firms.

Originality/value
The extant literature shows that independent directors are an effective mechanism to reduce agency problems in firm decisions and operating performance. However, there has been no research on the role of independent directors in corporate investment policy.

Authors: Addy Michael Nii , Akunyumu Stephen , Simons Barbara 
Published: August 2019

Purpose
Sustained access to efficient electricity plays an essential role in improving living conditions of people and contributes to the economic development of the nation as a whole. Volta River Authority (VRA) mainly manages the generation plants (hydropower sources and thermal plants) alongside independent power producers (IPPs). Power generation in the country has been influenced by myriads of factors. Thus, the purpose of this study is to assess the key risk factors affecting renewable energy of IPPs set-up project in Ghana.

Design/methodology/approach
Quantitative approach was adopted for the study. Empirical investigation was carried out using the survey approach. The likelihood of occurrence of the risk and the degree of impact of same motivated the use of risk significance index to analyze the data and make deductions from the results.

Findings
From the study, three key risk factors have high level of severity, which include long and complex procedures for authorization of project activities, stability of the policy environment and ease of obtaining rights to land. These risks could be found in the business/strategic risks and policy/regulatory risks categories, respectively. A total of 25 key risk factors had moderate level of severity and 12 key risk factors have low level of severity on renewable energy IPP set up projects.

Practical implications
Top-ranked risk factors require maximum attention. The identified risks should be alleviated with strategies to reduce levels of severity by targeting either the likelihood of occurrence or the level of impact. This will serve as a catalyze to promoting renewable energy IPP set-up projects in Ghana.

Originality/value
Key contribution of the paper to the body of knowledge is demonstrated by the empirical evidence of the risks IPPs are likely to encounter in setting up renewable energy plants in Ghana. The distinctive attribute of this study is further demonstrated by the fact that it focused on the set-up stage, which is a critical stage in the renewable energy provision value chain.

Authors: Pihlainen Vuokko , Kivinen Tuula , Lammintakanen Johanna 
Published: August 2019

PurposeThe purpose of this paper is to describe how Finnish experts perceive future (year 2030) hospital management and leadership.Design/methodology/approachA total of 33 experts participated in a three-round Argument Delphi process. Opposing views of management and leadership in 2030 were analyzed using inductive content analysis.FindingsThe experts’ perceptions were divided into two main categories: management and leadership orientation and future organization. Perceptions relating to management and leadership orientation were classified as relating to patient-centred, clinical dominance, professionally divided and management career options. Perceptions relating to future management and leadership organization were classified as representing shared, pair, team and the individual-centered leadership. The results highlighted the most distinctive issues raised by the participants.Research limitations/implicationsThis qualitative study was conducted in the context of Finnish healthcare according to the principles of the Argument Delphi Method. The panel consisted of high-level experts representing a diverse set of roles. However, as suggested in previous literature, these experts may not be the most astute in predicting the future development of hospital organizations.Practical implicationsThe findings can be used to develop and renew management and leadership training and management practices in hospitals.Social implicationsThe findings can be exploited in discussions, planning and decision making regarding future management and leadership in hospitals.Originality/valueOnly a few studies have investigated perceptions of future management in hospitals. This study adopted the Argument Delphi Method to identify distinct perceptions on the future orientation and organization of management and leadership in hospitals.
Intellectual capital and performance of Islamic and conventional banking
Authors: Buallay Amina 
Published: August 2019

Purpose
Intellectual capital (IC) is considered as a lifeblood of the high-tech and knowledge-based sectors. Therefore, there is a great need to highlight the importance of IC in the banking sector. Since the banking sector in the gulf countries is mainly based on Islamic and conventional banking, the purpose of this paper is to provide a comparative empirical analysis between IC efficiency in Islamic and conventional banks, and its impacts on a bank’s operational, financial and market performance.

Design/methodology/approach
This study examined 59 banks for five years to end up with 295 observations. The independent variable is the modified value added IC components; the dependent variables are performance indicators (return on assets, return on equity and Tobin’s Q). Two control variables are utilized in this study: bank-specific and macroeconomic.

Findings
The findings deduced from the empirical results demonstrate that there is a positive relationship between IC efficiency and financial performance (ROE) and market performance (TQ) in Islamic banks. However, in conventional banks, there is a positive relationship between IC and operational performance (ROE) and financial performance (ROE).

Originality/value
The results of this study can be used to present a successful model for the Islamic and conventional banks to concentrate more on the role of IC in enhancing the bank’s performance. In addition, the results of this study may provide a wake-up call for Islamic banks to examine the reasons for the imperfect relationship between the IC and asset efficiency (ROA), as well as for conventional banks to examine the reasons for an imperfect relationship between the IC and market value (TQ).

Authors: Lisi Gaetano 
Published: August 2019

PurposeThe purpose of this paper is to comment upon the use of hedonic pricing models for the valuation of property. This model can be particularly useful for some housing markets.Design/methodology/approachThis Education Briefing is an explanation of the how hedonic pricing can be useful in looking at the effect of “location” on the house prices within different submarkets using the Italian real estate market as an example.FindingsAlthough, this case study is relatively straightforward, it shows how the application of the market approach can provide insights in cases where the comparable properties belong to different submarkets with relatively few transactions.Practical implicationsIn cases of mass appraisals, hedonic pricing models can provide a broad indication of value across submarkets.Originality/valueThis paper develops a general framework that connects multiple regression analysis, direct comparison model and submarket binary variables.
Effect of temperature on stress–strain behaviour of pre-damaged confined concrete
Authors: Kumar Virendra 
Published: August 2019

PurposeThis paper aims to study the residual test results under uni-axial compression of tie confined pre-damaged normal strength concrete short columns subjected to elevated temperatures.Design/methodology/approachThe test variables included temperature of exposure, spacing of transverse confining reinforcement and pre-damage level. An experimental program was designed and carried out involving testing of hoop confined concrete cylindrical specimens exposed to elevated temperatures ranging from room temperature to 900 °C.FindingsThe test results indicate that the residual strength, strain corresponding to the peak stress and the post-peak strains of confined concrete are not affected significantly up to an exposure temperature of 300 °C. However, the peak confined stress falls and the corresponding strain increase considerably in the temperature range of 600 to 900 °C. It is shown that an increase in the degree of confinement reinforcement results in an increased residual strength and deformability of pre-damaged confined concrete.Research limitations/implicationsIt is applicable in finding the residual strength and strain of the pre-damaged confined concrete in uni-axial compression after exposure to elevated temperature.Practical implicationsThe practical implications is that the test result is applicable in finding the residual strengths of pre-damaged confined concrete under uni-axial compression after exposure to elevated temperature.Social implicationsThe main aim of the present investigation is to provide experimental data on the residual behaviour of pre-damaged confined concrete subjected to high temperatures.Originality/valueThe results of this study may be useful for developing the guidelines for designing the confinement reinforcement of reinforced concrete columns against the combined actions of earthquake and fire, as well as for designing the retrofitting schemes after these sequential disasters.
