The sea has involved a large variety of environmental contaminants and plays a crucial role in aquatic ecosystems. The Izmir Bay, which has been rapidly polluted since the 1960s, was one of the intensely polluted areas in the Mediterranean. Organic materials, hydrocarbons, metals, and pathogenic organisms that are accumulated in the region, caused high pollution and threaten health and aesthetics. Because of this, the aim of this paper was focus on to investigations of the genetic damages in mussels in Izmir Bay. Investigations of mutagenic/carcinogenic potential have an advantage in genotoxicity studies because biomarker for pollution exposure in mussel is the early detection of possible long-term effects such as cancer. Therefore, genotoxicity was the focus of the biomarker investigations in mussel during the investigations. Thus, micronucleus tests were afforded to determine genetic damage in the haemolymph, liver, and gills of Mytilus galloprovincialis living in Izmir Bay (Western Coast of Turkey). In the present study, results showed that the frequency of MN was found at a high level in station 4 and station 5 where wastes from dockyard existed contributed to the high level of pollution. The recommendation is to standardize procedures for assessment of the toxic impact of pollutants at the cellular level in aquatic species by using micronucleus assays for biomonitoring of environmental pollution.

The crustacean fauna associated with Mytilus galloprovincialis and Mytilaster minimus (Mollusca, Bivalvia) beds from Izmir Bay was investigated spatially in autumn 2014. Samples were collected by means of a quadrate sampler covering 400 cm2 at four intertidal stations from the inner (3 stations) and outer (a single station) parts of the bay. A total of 831 individuals belonging to 16 species of crustaceans, were collected and identified. Among these, the isopod Paradella dianae was the most dominant species represented with 227 individuals. Paradella dianae and the amphipod Hyale crassipes were the most frequent crustacean species on the mussel beds with 58.33% occurrence. The maximum crustacean biomass (306.29 g/m2) was calculated at station 4. The amphipods Stenothoe gallensis and Elasmopus pectenicrus, and the isopod P. dianae were the alien crustaceans encountered in the present study.

Авторами отмечается высокий уровень латентной преступности в данной отрасли. Предложены некоторые пути профилактики данной категории правонарушений. Исследование проводилось на основе анализа конкретных уголовных дел, возбужденных следственными органами по результатам оперативно-розыскной деятельности правоохранительных органов. In the article the authors consider the issues of criminal and legal protection of the fuel and energy complex of the Russian Federation from criminal activity including corrupt illegal practices of officials. The authors cite the results of some criminological characteristics study of the fuel and energy complex staff committed corruption crimes. As a result of these illegal actions significant damage is caused to the normal functioning of the fuel and energy enterprises. Such officials` actions determine not only a wide range of other illegal activities, but also lead to public outcry and discredit the industry as a whole. The analysis of the reasons and conditions contributing to the above illegal actions commission is given. A typical model of a criminal for a given crime category and its characteristics are determined. First of all it is a high level competence, special education, etc. A high level of latent crime in this industry is shown. The study results are presented on the example of specific criminal cases initiated by the investigating authorities based on the results of the operation detection activities of law enforcement agencies. Some ways of preventing this category of offenses are proposed.

In the 1960s it was widely assumed that a process of secularisation was taking place and was likely to continue. Recent empirical data about a council estate, which among other things relate religious variables to age, are thought to throw light on such questions. These findings demonstrate that ‘religiosity’ tends to increase with age, but that for certain purposes important elements of residual religiosity remain. The decline in Sunday School is particularly noteworthy, and suggests a movement in the direction of a ‘voluntary’ church. Remaining churchgoers have a high level of commitment, suggesting that a move from church to sect can operate in the mainstream church.

This paper aimed to explore the changes posed by the new COVID-19 pandemic to the field of social work and its impact on social workers in terms of job stress and burnout in Romania. Two conceptual models were used to frame the discussion: the theoretical framework of VUCA (volatility, uncertainty, complexity, and ambiguity) to discuss the challenges that the unprecedented context of the COVID-19 pandemic has created for social workers; and the Job Demands and Resources model (JD-R) to understand job demands perceived as stressors and burnout. Based on convergent mixed methods, the study sample consisted of 83 social workers employed in statutory and private social services in Romania, from different areas of intervention. Results showed that social workers perceived a high level of job stress related to work during the pandemic, which was associated with higher levels of burnout in the areas of personal burnout (average score 55.9) and work-related burnout (average score 52.5). Client-related burnout was lower (average score 38.4), indicating that stress was generated mainly by organisational factors and work-related factors (workload, aligning to new legislative rules and decisions, inconsistency, instability, ambiguity of managerial decisions, and lack of clarity of working procedures) and less by client-related stressors (lack of direct contact with clients, risk of contamination, managing beneficiaries’ fears, and difficulties related to technology). High job demands and limited job resources (managerial and supervisory support, financial resources, and recognition and reward) led to a high to very high level of work-related burnout for 15.7% and an upper-medium level for 44.2% of respondents. A group of 27.7% reported lower to medium levels of work-related burnout, while 14.5% had very low levels, managing to handle stress factors in a healthy manner. Study results pointed to the importance of organisational support and the development of a self-care plan that help to protect against job stress and burnout. Recommendations were made, putting forward the voice of fieldworkers and managers fostering initiatives and the application of sustainability-based measures and activities designed to deal with the challenges of the VUCA environment.

Purpose This study/ paper aims to empirically examine the user attitude on perceived security of enterprise systems (ES) mobility. Organizations are adopting mobile technologies for various business applications including ES to increase the flexibility and to gain sustainable competitive advantage. At the same time, end-users are exposed to security issues when using mobile technologies. The ES have seen breaches and malicious intrusions thereby more sophisticated recreational and commercial cybercrimes have been witnessed. ES have seen data breaches and malicious intrusions leading to more sophisticated cybercrimes. Considering the significance of security in ES mobility, the research questions in this study are: What are the security issues of ES mobility? What are the influences of users’ attitude towards those security issues? What is the impact of users’ attitude towards security issues on perceived security of ES mobility? Design/methodology/approach These questions are addressed by empirically testing a security model of mobile ES by collecting data from users of ES mobile systems. Hypotheses were evolved and tested by data collected through a survey questionnaire. The questionnaire survey was administered to 331 users from Chinese small and medium-sized enterprises (SME). The data was statistically analysed by tools such as correlation, factor analysis, regression and the study built a structural equation model (SEM) to examine the interactions between the variables. Findings The study results have identified the following security issues: users’ attitude towards mobile device security issues; users’ attitude towards wireless network security issues; users’ attitude towards cloud computing security issues; users’ attitude towards application-level security issues; users’ attitude towards data (access) level security issues; and users’ attitude towards enterprise-level security issues. Research limitations/implications The study results are based on a sample of users from Chinese SMEs. The findings may lack generalizability. Therefore, researchers are encouraged to examine the model in a different context. The issues requiring further investigation are the role of gender and type of device on perceived security of ES mobile systems. Practical implications The results show that the key security issues are related to a mobile device, wireless network, cloud computing, applications, data and enterprise. By understanding these issues and the best practices, organizations can maintain a high level of security of their mobile ES. Social implications Apart from understanding the best practices and the key issues, the authors suggest management and end-users to work collaboratively to achieve a high level of security of the mobile ES. Originality/value This is an empirical study conducted from the users’ perspective for validating the set of research hypotheses related to key security issues on the perceived security of mobile ES.
