Abstract
Purpose
The purpose of this study is to evaluate the effect of Hibiscus sabdariffa ethanolic extract (HsE) on protein levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, adiponectin and leptin in adipose tissue, as well as on the lipid and glycemic profiles of high-fat/sugar diet-induced obese (DIO) rats.
Design/methodology/approach
Obesity was induced in male Wistar rats through a high-fat/sugar diet provided for eight weeks. Control rats received a standard diet. The high-fat/sugar DIO animals were subsequently randomized into DIO (n = 8) and DIO treated with HsE (DIO + HsE, n = 8, 150 mg/kg/day) by gavage, for additional eight weeks. Oral glucose tolerance test was performed, and blood samples and epididymal adipose tissue were collected for biochemical analysis and adipokine protein level evaluation, respectively.
Findings
Compared to the DIO rats, HsE treatment decreased weight gain (50.6%) and mesenteric fat (42%), indicated as diminished visceral fat (22.5%). HsE did not affect the lipid profile and TNF-α levels in adipose tissue; however, it effectively prevented a 13% increase in fasting glucose levels and improved glucose tolerance. Compared with the C group, HsE normalized the adiponectin levels and leptin/adiponectin ratio and decreased the IL-6 (55%) and leptin (18.6%) levels in adipose tissue of obese rats.
Originality/value
HsE improves adipokine protein levels in high-fat/sugar DIO rats, demonstrating the clinical efficacy of HsE in the treatment of obesity and obesity-related diseases.

Abstract
Purpose
This paper aims to provide a detailed case study of a corporate foresight for innovation (CFI) project done by the Higher School of Economics’ (HSE) (Moscow, Russia) corporate foresight (CF) unit for a large state-owned Russian service company. It demonstrates how CFI methods lead to recommendations and how these recommendations result in decisions.
Design/methodology/approach
Drawing from being part of the project team, review of the project documents and interviews, the case describes a multi-phased CFI project which incorporated several CF methods. Techniques used for the project itself included grand challenges and trend analysis, analysis of best practices through use of benchmarking and horizon scanning, interviews, expert panels, wild card and weak signals analysis, cross impact analysis, SWOT and backcasting. The project used a broad-base of secondary information, expert panels consisting of company experts and HSE CF team personnel, interviews with senior management and an extensive literature review using HSE’s propriety iFORA system.
Findings
In all 17 CFI recommendation and over 100 implementation recommendations were made; 94 per cent of the CFI recommendations were accepted with most implemented at the time this case was written. The case also identifies five enabling factors that collectively both helped the CFI project and led to a high rate of recommendation acceptance and one factor that hindered CFI project success.
Practical implications
The case study provides detailed information and insight that can help others in conducting CF for innovation projects and establishes a link between CF methods and innovation-based recommendations and subsequent decisions.
Originality/value
In-depth case studies that show academe and practitioners how CFI leads to recommendations and is linked to subsequent decisions have been identified as a gap in the literature. This paper therefore seeks to address this need by presenting a detailed CF case for a corporate innovation project.

Abstract
Purpose
This paper aims to assess the ways through which the concept of health, safety and environment (HSE) is perceived by workers in the United Arab Emirates (UAE) oil and gas industry. The study focused on different aspects of the HSE culture and how employees with and without leadership responsibilities differed in their conceptualization of HSE culture.
Design/methodology/approach
Semi-structured interviews were conducted for 30 staff of the state-owned Abu Dhabi National Oil Company in the UAE. The interviewees were purposively selected which included both those in leadership and non-leadership roles.
Findings
The findings revealed that the interviewees viewed HSE culture as a descriptive term, a causal phenomenon, a systemic approach or a legal requirement/obligation. Interviewees in the production and maintenance units mentioned safety most often. Employees and managers exhibited negligible differences in their usage of the HSE culture concept. Managers predominantly featured in the narratives as important drivers of HSE culture. Physical conditions, behavior and procedures, management, competence and collaboration emerged as important components of a sound HSE culture.
Originality/value
To enable better communication and subsequent improvement of the HSE culture, an analogical HSE culture “vehicle” was developed in the study. The vehicle is a novel illustration based on the key roles of managers and employees, as well as the main components of a sound HSE culture.

Abstract
Purpose
Project management generally covers many important areas such as cost, quality and time in different industrial settings, but it is deficient in relation to integration of health, safety and environmental risks. Poor knowledge of project managers about HSE management necessitates the studying on the mutual effects of HSE and project management. Hence, investigating the impact of project management on health monitoring programs, safety prevention monitoring, environmental monitoring plans and finally the effectiveness of professional health monitoring programs and determining their importance are main objectives of this research. The paper aims to discuss these issues.
Design/methodology/approach
A model based on structural equations was designed and developed. The constructs of this model are project management, health monitoring and safety prevention monitoring program. Based on the conceptual model, some questionnaires were prepared and distributed among the experts of strategic project management.
Findings
The results of applied structural modeling suggest that project management focuses on each aspect of HSE management, including health monitoring programs, safety prevention monitoring programs, environmental monitoring plans and effectiveness of professional health monitoring programs. HSE management can also be strengthened by empowering project management. Checking fire protection systems, using appropriate techniques to identify contamination and disposal of waste and incorporating techniques for brainstorming or other ideas creation in the group are the most important tasks in HSE-enabled project management frameworks.
Originality/value
Since there is still no strategic alignment model that includes components of project management and HSE management, a model for achieving this goal is vital. This paper elaborates this alignment based on literature and using a field study.

Abstract
Purpose
Performance Management (PM) processes have become a potent part of strategic and service quality decisions in healthcare organisations. In 2005, the management of public healthcare in Ireland was amalgamated into a single integrated management body, named the Health Service Executive (HSE). Since then, the HSE has come up with a range of strategies for healthcare developments and reforms, and has developed a PM system as part of its strategic planning. The purpose of this paper is to review the application of PM in the Irish Healthcare system, with a particular focus on Irish Hospitals and Emergency Services.
Design/methodology/approach
An extensive review of relevant HSE’s publications from 2005 to 2013 is conducted. Studies of the relevant literature related to the application of PM and of international best practices in healthcare performance systems are also presented.
Findings
PM and performance measurement systems used by the HSE include many performance reports designed to monitor performance trends and strategic goals. Issues in the current PM system include inconsistency of measures and performance reporting, unclear strategy alignment, and deficiencies in reporting (e.g. feedback and corrective actions). Furthermore, PM processes have not been linked adequately into Irish public hospitals’ management systems.
Research limitations/implications
The HSE delivers several services such as mental health, social inclusion, etc. This study focuses on the HSE’s PM framework, with a particular interest in acute hospitals and emergency services.
Originality/value
This is the first comprehensive review of Irish healthcare PM since the introduction of the HSE. A critical analysis of the HSE reports identifies the shortcomings in its current PM system.

Abstract
Purpose
Concern for health, safety and environment (HSE) is increasing in many developing countries, especially in energy industries. Improving power plants efficiencies in terms of HSE issues requires considering these issues in performance assessment of power generation units. This study aims to discuss the use of data envelopment analysis methodology for the performance assessment of electrical power plants in Iran by considering HSE and conventional indicators.
Design/methodology/approach
Installed capacity, fuel consumption, labor cost, internal power, forced outage hours, operating hours and total power generation along with HSE indices are taken into consideration for determining the efficiency of 20 electric power plants or decision-making units (DMUs). Moreover, DMUs are ranked based on their relative efficiency scores.
Findings
Results show that HSE factors are significant in performance assessment of the power plants studied in this research, and among HSE factors, health has the most powerful impact on the efficiency of the power plants.
Originality/value
The approach of this study could be used for continuous improvement of combined HSE and conventional factors. It would also help managers to have better comprehension of key shaping factors in terms of HSE.

Abstract
Purpose
The purpose of this paper is to evaluate the health‐states of unit under test (UUT) in aerospace systems by means of unreliable test outcomes, and the evaluation results can provide a guide for engineers to carry out proper maintenance prior to total failure.
Design/methodology/approach
In this paper, the authors formulate the health‐state evaluation (HSE) problem with unreliable test outcomes based on Bayes rule, and develop the Lagrangian relaxation and adaptive genetic algorithm (LRAGA) to solve it. The solution scheme can be viewed as a two‐level coordinated solution framework for the HSE problem. At the top level, the Lagrange multipliers are updated by using AGA. At the bottom level, each of the sub‐problems is solved by using AGA.
Findings
The experimental results show that the HSE model appears promising and the LRAGA can obtain the higher quality solution and converge to it at a faster rate than conventional methods (i.e. Lagrangian relaxation (LR), genetic algorithm (GA), simulated annealing (SA) and Lagrangian relaxation and genetic algorithm (LRGA).
Research limitations/implications
The proposed method for the HSE problem of large‐scale systems which include thousands of faults and tests needs to be verified further.
Practical implications
The HSE results for aerospace systems can help engineers to carry out a schedule for prompt maintenance prior to UUTs' failure, to avoid the consequences of total failure. It is important to improve aerospace systems' safety, reliability, maintainability, affordability, and reduce life cycle cost.
Originality/value
This paper constructs the HSE model with unreliable test outcomes based on the Bayes rule and proposes a method based on LRAGA to solve the HSE problem.

Abstract
Purpose
The purpose of this paper is to take the perspective of repairing the negative effect of social exclusion, discussing how anthropomorphized brand role (partner vs servant) releases the negative effect of social exclusion.
Design/methodology/approach
In this research, two behavioral studies are conducted. Study 1 uses a one-factor (social exclusion vs social inclusion) between-subjects design. The purpose of Study 1 is to test the effect of social exclusion on consumers’ WTP for the anthropomorphized brand (H1). Study 2 uses a 2 (self-esteem (SE): high vs low) × 2 (anthropomorphized brand role: servant vs partner) between-subjects design. The aim of Study 2 is to investigate that after being socially excluded, how anthropomorphized brand roles (servant vs partner) and SE interactively release individuals’ negative feelings (H2a and H2b) and how the need for control recovery mediates this interaction effect (H3).
Findings
This study proposes that when individuals are socially excluded, they are willing to pay more for anthropomorphized brands than those who are not because anthropomorphized brands provide a quasi-social relationship. This study further posits that socially excluded consumers prefer the different role of anthropomorphized brands, given a different level of SE to meet their needs for control recovery. High self-esteem (HSE) (vs low self-esteem (LSE)) consumers are willing to pay more for a servant-like brand because such brands help them recover from low control by regaining a master role. In contrast, HSE and LSE consumers have no significant differences in WTP for a partner-like brand.
Originality/value
Few research studies have discussed how social exclusion influences individuals’ WTP. To fill this gap, the authors used WTP as the dependent variable, showing that after being socially excluded, individuals tend to pay a higher price for the anthropomorphized brand. Also, the research not only adds a contribution to research on the need for control recovery but also indicates how HSE vs LSE individuals behave differently in socially excluded contexts.
