The purpose of this paper is to study the effect of ultraviolet radiation (UVC) on the survivability and susceptibility of some fungal species isolated from the indoor air of agricultural, industry‐related workplaces.

Environmental fungi were collected from the air of cotton and soybean mills using liquid impinger sampler (AGI‐30). The UVC exposure experiment was performed on Aspergillus flavus, Aspergillus parasiticus, Aspergillus ochraceous, Aspergillus fumigatus, Aspergillus niger and Penicillium rubrum using UV lamp (λ=254 nm; 0.1 mW/cm²). The susceptibility constant (Z) was used to determine the susceptibility of any given organism to UVC.

The conidia survival was inversely proportional to the time of UVC exposure and ∼77‐88.5% of conidia were killed within six hours of exposure. Mutant conidia showed a wide range of morphological alterations including damage of their cell walls and features. Mycotoxin production patterns of the mutants Aspergillus flavus and Aspergillus parasiticus changed on comparison with the parental control patterns.

The paper provides information on the effect of UVC radiation on environmental fungi. The results reported in this research discussed the disadvantages of using UVC as a decontaminant of fungi.

The purpose of this paper is to investigate the efficacy of cabbage powder as a source of natural antioxidants and dietary fibre for the development of functional mutton patties. Antioxidants are the first line of defence against the oxidative damage to body’s macromolecules resulting in pathogenesis of various diseases including cancers and cardiovascular diseases. The supply of antioxidants from vegetative sources along with different meat products may serve as an excellent alternative for the synthetic antioxidants which may have harmful effects.

Cabbage powder was prepared and evaluated for antioxidant potential and total dietary fibre content. Cabbage powder was incorporated at three different levels in mutton patties formulation; optimum level was selected on the basis of sensory analysis. The developed product was evaluated for detailed profile and storage stability under aerobic and vacuum packaging.

Cabbage powder may serve as a good source of natural antioxidant and dietary fibre for the development of functional mutton patties. On the basis of sensory scores, optimum incorporation level of cabbage powder was adjudged as 6 per cent. The functional mutton patties had very good storage life under refrigeration.

Future research may stress on identifying the specific compounds with antioxidant effect and their metabolism inside the body.

This paper may popularize the cabbage powder as a source of natural antioxidant and dietary fibre in different food products.

Development of functional mutton patties incorporated with cabbage powder having oxidative stability, good nutritive, sensory, textural, and colour properties.

This study aims to explore the corporate social responsibility disclosure (CSRD) practices of the Islamic banks in the Gulf Cooperation Council (GCC) countries during the period 2010-2014 and examines the determinants of CSRD and its effects on firm value.

Based on the Accounting and Auditing Organization for Islamic Financial Institutions Governance Standard No. 7 guidelines and using content analysis, the paper develops a comprehensive CSRD index for GCC Islamic banks. The study applies ordinary least squares regression analysis for hypothesis testing and for finding determinants of respective dependent variables.

The results show a very low level of CSRD among the sample Islamic banks in GCC countries. When using corporate governance characteristics to examine the determinants of CSRD, this study provides evidence of a significant positive association between board size and CSRD practice in Islamic banks and a significant negative relationship of chief executive officer (CEO) duality with CSRD, as per expectation. For the economic consequences of CSRD, the study documents an inverse performance effect of CSRD while board size, board composition and CEO duality indicate significant positive effects on firm value.

The relatively small sample size of GCC Islamic banks may limit the application of the findings to other Islamic financial institutions such as Takaful and the Islamic unit trust company.

The findings of this study initiate the global debate on the need for corporate governance reform in Islamic banks by providing insights on the role played by corporate governance mechanisms in encouraging and enhancing CSRD practices among Islamic banks. The findings also have important implications for investors, managers, regulatory bodies, policymakers and Islamic banks in the GCC countries.

The results of the study do not support the idea that Islamic banks operating on Islamic principles can meet their social responsibilities through promoting corporate social responsibility (CSR) activities and by differentiating themselves from non-Islamic banks.

This is the first study to examine the determinants of CSRD in GCC Islamic banks using comprehensive CSRD and corporate governance variables and, therefore, adds value to the existing CSR literature in banking.

This study aims to focus on the factors triggering the adoption of corporate social responsibility (CSR) practices in a developing country context. The authors examine whether the adoption of CSR practices is triggered more by internal efficiency forces or external legitimation forces. As early adoptions of new systems are more likely driven by efficiency motives, the authors argue that CSR practices in developing countries at nascent stages are more likely adopted for efficiency rather than legitimation reasons.

A cross-sectional sampling design was used to collect data on the CSR practices of top listed Egyptian firms and multinationals operating in Egypt. The sample size is selected based on a purposive criterion sampling method. The final sample size consists of 110 companies operating in Egypt, which includes 54 local and 56 multinational companies. To examine the relationship between the explanatory variables of the study and CSR, multiple regression analysis was used.

Using data from 110 top listed local companies and multinational firms operating in Egypt, the results show a significant influence of internal corporate governance on CSR. Yet, the effects of external factors, specifically legal regulations and stakeholder pressures, on CSR are perceived to be insignificant. This finding contrasts studies from industrialized countries in the Western world where firms are often motivated to invest in CSR by external forces.

The results indicate that the adoption of CSR practices in large firms in Egypt is driven more by internal efficiency gains rather than external legitimacy pressures. The study thus presses the need for the effective enforcement of governmental laws and regulations to strengthen external institutional pressures and demands for socially responsible behavior.

The results of the study indicate a perceived absence of stakeholder pressure for CSR practices. As such, raising awareness for corporate accountability amongst Egyptian consumers, employees and the general public would increase corporate incentives to improve their social and environmental performance. In addition, the concept of CSR must be cultivated in the organizational culture where high value is placed on corporate ethics and managerial values.

This study provides insights about the predominant drivers of CSR in Egypt on two different levels; the organizational and the business environment. Salient links between CSR, internal corporate governance mechanisms and external drivers such as external stakeholder and legal pressures are explored. The results of the study also emphasize the importance of internal corporate governance mechanisms and how it is perceived to be the main driver of CSR in Egypt as opposed to external influences.

This paper aims to investigate the moderating effect of cultural dimensions (masculinity, individualism and long-term orientation) on the association between profitability and corporate social and environmental disclosure (CSED).

The authors apply the meta-analysis technique developed by Hunter et al. (1982) and Hunter and Schmidt (2000) for a sample of 48 published studies over the period of the past 20 years.

The authors find that masculinity, individualism and long-term orientation moderate the association between profitability and CSED. Given the weight of US studies on the overall sample, the authors conduct a sensitivity analysis to examine how this factor may affect the findings. After excluding these studies, only long-term orientation and individualism remain strong moderators of the association between profitability and CSED.

This study provides further evidence on the impact of institutional frameworks on CSED. It has, also, policy implications for managers of multinational corporations.

According to a study by European Commission, 88m tons of food waste are generated per year, of which 46.5m tons are wasted by households. Households still remain the main source of food waste (53 percent). The purpose of this paper is to estimate households’ food waste and wastage-related losses of energy and nutrients among middle school students as well as assess educational intervention regarding food waste prevention.

The study included 555 students from 11 schools in Poland. The study was conducted using the survey questionnaire and the three-day record of food waste. The interventional group filled a questionnaire before and after of education as well as after three months of intervention.

Students waste 23 g of food per day. The most wasted products are: potatoes, bread, fruits and vegetable as well as meet and ham. Energy losses from leftovers are less than 1–10 percent. Losses of nutritional value along with wastages were the highest for vitamin C, but also for dietary fiber, potassium and folate. Food waste education was nearly twice as strong in study group with films intervention, than those who received only a leaflet for parents.

Middle school students are responsible for households’ food waste and contribute to energy and nutrition losses. Educational intervention is more effective, while using multimedia methods and need to be continued.

The paper is a scientific study and addressed to the scientific audience. However, due to the problem of households’ food waste, general public could be also interested.

Food waste is an element of waste management. Studying the scale of food waste and waste related behavior can help to better understand causes of food waste. The search for ways to limit food waste, through education address to young people, can be an effective method of prevention of waste. The UN has established 17 new development goals for the years 2015–2030 (United Nations, 2015). One of them (Goal 12) is focused on ensuring sustainable consumption and production. It means halving food waste at the retail and consumer levels and food losses at the production and post-harvest stages by 2030.

There are few publications available about food waste including energy and nutrients waste. This study shows the scale of household waste, the quantity and type of wasted products and causes of disposal. Also, the way of handling with food waste at homes was examined. It is also important to draw attention to the responsibility of young people in wasting food, which was examined in the paper.

Increased acceptance of automation by management has changed the role of a typical industrial worker. These days workers are required more and more to use their manual and decision making capabilities. The designers of man‐machine systems, who are required to predict the performance of such systems, do not have available to them well‐tested techniques suitable for making such predictions. Some methodologies are available which assume the additivity of manual and decision times. Current experimental work has indicated that a certain informational load does not affect equally the performance time for various sub‐sections of a given task when discrete type motions are made. Various types of motions, i.e., move, position, etc., having different magnitudes have been investigated to study the effect of informational load on performance time. Informational loads were varied by changing the set size and the statistical structure of the same set. In addition to the description of Type II Tasks, findings of four studies are discussed. Based on the findings a set of guidelines is presented which may be used by the designers of tasks involving human decision making and manual motions.

The purpose of this paper is to synthesise carboxymethylcellulose and methyl methacrylate graft copolymers (CMC‐g‐PMMA), which is used as an effective additive, for reinforcing the rice‐hull‐cement composite.

Various CMC‐g‐PMMA copolymers were synthesised at different reaction temperatures, pH values of reaction solution and the dosages of monomer and initiator (potassium persulphate). The copolymers were characterised by Fourier transforms infrared (FT‐IR) spectra, thermal analysis (thermogravimetric and differential scanning calorimeter), X‐ray diffractometry (XRD) and scanning electron microscopy.

An optimal CMC‐g‐PMMA copolymer is obtained. For synthesis of the CMC‐g‐PMMA, the optimal reaction temperature is 80°C and pH value is 9. FT‐IR test of CMC‐g‐PMMA confirmed the existence of a chemical link between carboxymethylcellulose (CMC) and methyl methacrylate (MMA). The content of initiator has little effect on the reaction for synthesising the graft copolymer. Thermal analysis indicates the occurrence of graft reaction in CMC and MMA. XRD test proved that the chains of the graft copolymer can enlarge the proportion of the amorphous regions of CMC. Adding MMA has damage effect on the crystallisation.

Since the results of this paper are obtained from the laboratory experiments, further research should be conducted for evaluating the performances of this copolymer in practical application.

The mechanical test of the rice‐hull‐cement composite proved that CMC‐g‐PMMA is an effective additive for reinforcing the rice‐hull‐cement composite. The synthesis of CMC‐g‐PMMA provides a new alternative for modifying cellulose derivatives.

The CMC‐g‐PMMA obtained in this paper is a new kind of effective agent. It can reinforce the rice‐hull‐cement composite and expands the application of the composite in building industries.

This paper aims to examine the factors affecting the implementation of corporate social responsibility (CSR) sustainably in mobile operators in the kingdom of Bahrain.

The research relies on the existing literature as a secondary data source. The primary data was collected through questionnaires distributed to three leading mobile operators in the Kingdom of Bahrain. The research's population numbered 1,689, and the sample size was 313; the simple random sampling method was used for data collection with a response rate of 87.2% out of a total sample size of 273 respondents. In addition, the responses were analyzed using statistical package for the social sciences (SPSS) software version 24.0; specifically, Spearman's rank correlation was used to test the hypotheses. The research design was quantitative, so a nonparametric procedure was applied to test the hypotheses.

The research produced positive relationships between the independent variables (economic, legal, ethical, philanthropic and environmental responsibilities) and the dependent variable: CSR implementation by Bahrain mobile operators; therefore, the five proposed hypotheses were accepted; furthermore, the highest positive correlation coefficient was 0.735 for environmental responsibility, and the lowest correlation coefficient was 0.533 for economic responsibility.

The research produced positive relationships between the independent variables (economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility and environmental responsibility) and the dependent variable: CSR implementation by Bahrain mobile operators; therefore, the five proposed hypotheses were accepted; furthermore, the highest positive correlation coefficient was 0.735 for environmental responsibility, and the lowest correlation coefficient was 0.533 for economic responsibility.

The outcomes of the research mainly suggest that mobile operators assign employees who have been working with the company for more than 7 years to implement CSR; due to their engagement to implement CSR as a sustainable practice more than others with less than 3 years or 3-6 years in Bahrain mobile operators. Besides, the research provides a starting point by which other researchers could investigate CSR in other sectors in the Kingdom of Bahrain.

The research provided a framework for Bahrain mobile operators to assist them in enhancing the implementation of CSR in a sustainable manner, which are economic, legal, ethical, philanthropic and environmental responsibilities.

This study aims to discover the corporate social responsibility (CSR) disclosure practices and the potential influence of corporate governance (CG), ownership structure and corporate characteristics in an emerging Arab country, Saudi Arabia. This study extends the extant literature by investigating the drivers of CSR disclosure in a country that lacks research in this area.

This study examines 267 annual reports of Saudi Arabian non-financial listed firms during 2007-2011 using manual content and multiple regression analyses and a checklist of 17 CSR disclosure items based on ISO 26000.

The analysis finds that the CSR disclosure average is 24 per cent, higher than 14.61 and 16 per cent found by Al-Janadi et al. (2013) and Macarulla and Talalweh (2012) for two Saudi Arabian samples during 2006-2007 and 2008, respectively. This improvement may be due to the application of Saudi CG code in 2007. The analysis also shows that government and family ownership, firm size and firm age are positive determinants of CSR disclosure, firm leverage is a negative determinant and effective AC, board independence, role duality, institutional ownership, firm profitability and industry type are found not to be determinants of CSR disclosure.

This study is important because it uses the agency theory to ascertain the influence of specific board characteristics and ownership structures on disclosure. As a result, it provides important implications for CG regulators and different stakeholders and provides an evaluation of the recently applied Saudi CG code from the CSR disclosure perspective.
