Tabor, Joanna. "Fuzzy Topsis in the Assessment of OHS Management System." System Safety: Human - Technical Facility - Environment 1, no. 1 (March 1, 2019): 18–25. http://dx.doi.org/10.2478/czoto-2019-0003.
Full textAbstract:
AbstractOccupational health and safety (OHS) management is a cycle of decision-making processes, many of which are in fact multi-criterion processes in nature. Therefore, it is important to look for and develop tools to support decision-makers in their actions aimed at improving work safety levels. The objective of this paper is to propose and verify the fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method applied to compare and assess the ways OHS management systems function in different companies. The fuzzy TOPSIS method has already been used for a number of years in assessments of alternative solutions in many different areas, but the application that uses ordered fuzzy numbers is quite original in nature. It is especially beneficial to use the fuzzy approach in OHS management systems, as it makes it possible for experts to assess different criteria using most frequently used linguistic variables. The adopted approach was verified in the study of OHS management systems in four furniture manufacturing companies. Assessment criteria were requirements of the PN-N 18001: 2004 Standard. Thanks to the ordered fuzzy TOPSIS method, the analysed OHS management systems were streamlined from the point of view of 24 assessment criteria, and the best and the worst functioning system was identified. The approach presented here may constitute a significant tool for improving OHS management systems.

Full textAbstract:
About 67% of workers employed in the industrial and service sectors in the European Union are currently contracted by Small- and Medium-sized Enterprises (SMEs), which represent the economic heart of the European economy. However, this strength is counterbalanced by a considerably higher overall accident rate compared to Large Enterprises (LEs), and this trend seems to be confirmed worldwide. Moreover, most available tools for risk assessment and occupational health and safety (OHS) management are originally designed to fit the needs of LEs, resulting in a gap for SMEs. Therefore, the effective management of OHS in SMEs has become a crucial issue for researchers, practitioners and policymakers, aiming to improve the social and economic sustainability of small companies. The main purpose of this study is to provide guidelines to implement effective risk assessment processes and integrate them with OHS management systems in SMEs. A literature analysis of risk assessment and OHS management in SMEs highlights the main findings and gaps. Then, the three-phases methodology adopted is presented, outlining the main steps and outputs of the project. Finally, the web-based software tool for OHS risk analysis and management, designed to answer the specific needs of SMEs, is presented.

AbstractCurrently operating enterprises are more and more willing to adopt a process approach in their structures. The process approach means the transition from traditionally understood management towards adapting to constantly changing environmental conditions. This change is accompanied by the possibility of using a wide range of tools of ICT technology, that allow modelling of any type of process occurring in the enterprise, including processes related to OHS. Thus, the objective of the paper is to indicate the opportunity for the integration of OHS processes with other processes (primary and auxiliary) of the organization using ERP systems. In the first part of the study, there will be indicated the determinants of the development of the process approach in modern enterprises. Subsequently, there will be characterized OHS processes against the background of other processes of the organization. In the third part, there will be indicated the most significant features of ERP systems. The last part will refer to the practical implementation of the process in the area of OHS in the Macrologic Merit system.

Despite the popularity of online health services (OHSs) among patients in recent years, academic research on this phenomenon is limited. Drawing on the valence framework, the authors proposed a model to explore both the most important facilitators of OHS use intention from the perceived value perspective and inhibitors of OHS use intention from the perceived risk perspective. Data were collected from 407 OHS users through an online survey. Results showed that the inhibitors of OHS use intention include privacy risk and social risk, while facilitators include social support value, convenience value, and utilitarian value. These findings enrich the OHS literature by revealing both the inhibitors and facilitators of OHS use intention. This study also provides practical implications for platforms offering OHS in relation to effectively attracting users.

Full textAbstract:
The development and enhancement of occupational health services (OHS) at the national level is central to ensuring the sustainable health, well-being and work engagement of the working population. However, due to differences in national health, social security and occupational safety and health systems, the content, capacity, coverage and provisions of OHS vary considerably across national contexts. Obtaining a better understanding in terms of such similarities and variations internationally is essential as such comparative information can help inform evidenced-based decision-making on OHS at both policy and practice levels. This paper therefore reviews and analyses the key policies, standards and approaches in OH systems and services, using both academic and grey literature, across 12 industrialised countries (Australia, Canada, Finland, France, Germany, Ireland, Italy, Japan, The Netherlands, Poland, United Kingdom and the United States of America). It provides a detailed overview and categorization of OHS in these selected countries in terms of the legal and policy context, organisation and financing and coverage and staffing while specifically discussing variations aimed at psychosocial risk management and the promotion of mental health and well-being at work. It draws conclusions on key development needs of OHS internationally to ensure psychosocial risk management and mental health promotion are prioritised effectively in a preventive manner.

Full textAbstract:
OHS management systems and professionals have done much to ensure the health and safety of workers and societies in general. However, where these systems have become complex, overbearing and authoritarian, they have stifled workers and the community’s ability to respond to unique or unanticipated occurrences of occupational and general risk. This predicament is exacerbated when the general public lose faith in an OHS culture that has “gone mad”, or become “out of control”, and where “open season” has been declared by the media on safety regulators, their systems and regulations. This may be a perceived rather than actual truth, however, perceptions drive personal attitudes and responses, and the reputation and effectiveness of OHS is at stake. Driving some contemporary attitudes towards OHS is a barrage of lampoon, satire and angry comment pervade by mischief-makers, the press and the electronic media. The profession has also looked into the mirror and revealed areas of self-doubt. This paper looks at an unfolding and worrying scenario for occupational health.

Full textAbstract:
The aim of paper is to understand the role and significance of supply chain leverage in promoting health and safety management at sea, the institutional contexts in which it occurs and under which circumstances it is effective. This is a qualitative research study that examined the views of seafarers and their managers on what drives the implementation of occupational health and safety (OHS) management arrangements in two shipping sectors, namely, the independent oil and chemical tanker trade and the container trade. It is based on interviews with seafarers working on board several of these vessels and with representatives of the companies managing and operating the ships. As might be anticipated from previous theorizing of supply chain effects on OHS, the study found there to be strong evidence of its influence on OHS management arrangements on tankers. The most significant driver of this effect for both managers and seafarers appeared to be the surveillance of their OHS arrangements instituted by the heads of the supply chain—in this case the oil majors and their inspection systems. Perhaps more surprisingly, despite the more diffuse, transactional and arms-length supply arrangements in the container trade, in the one case study from this sector examined in the paper, supply chain influences on OHS were nevertheless discernable. However, it also demonstrated the positive role played by the framework for maritime regulation in determining the significance of these influences. Essentially, the results indicate that, under certain conditions, supply chain relations are useful in helping to support implementation of arrangements for OHS management on merchant vessels. However, it also more broadly demonstrates that such leverage is most likely to be effective when it operates within a wider institutional framework in which public regulation and its surveillance by regulatory authorities remains a key element.

AbstractThe paper discusses options for assessing risks with a view to identifying the nature and scope of the impacts of non-conformities and defining improvement opportunities. Such options are described in terms of hazards and opportunities. The opportunities reflect the measures required to increase the chances of establishing more effective safety management systems. The hazards reflect the circumstances that may prevent organizations achieving the desired benefits and that must therefore be eliminated in the course of system deployment and operation. Once identified, the above will help build the capacity to improve the existing management system in any organization that seeks to systemically modify its occupational safety system. The paper invokes the requirements set forth in ISO 45001, which it cross-references with binding legislation (including Directive 89/391/EEC). The approach helps define the benefits to be derived from assessing risks with a view to identify improvement opportunities and hazards by methods best suited to an organization’s environment.

Full textAbstract:
Certified occupational health and safety (OHS) management systems have become a global instrument in regulation of the work environment. However, their actual impact on OHS—in particular on softer psychosocial issues in the work environment—has been questioned. The most important standard of OHS management is OHSAS 18001, which has recently been supplemented with a British publically available guideline (PAS 1010) focusing specifically on psychosocial risk management. On the basis of the international literature on management standards, the present paper analyses OHSAS 18001 and PAS 1010 in order to understand the mechanism by which they work. The paper takes a social constructionist approach conceptualizing standards and their expected mechanisms as socially constructed—based on a particular kind of knowledge and logic—although they are presented as objective. Such a constructionist approach also emphasizes how standards transform specific work environment problems into generic procedures that can be audited. In the case of OHS standards, both the work environment in general and the psychosocial risks in particular are transformed into simple monocausal auditable relations whereby the complexity of psychosocial work environment issues seems to disappear. The new PAS 1010 guideline, which is particularly focusing on regulation of the psychosocial work environment, only partly succeeds in solving these shortcomings of OHSAS 18001.

The development and dissemination of new technologies has brought forward a rise in flexible work arrangements, such as mobile work. In the literature, mobile work has mostly been discussed from a microergonomic perspective, considering detachment, stress, strain, and life-domain balance. However, the macroergonomic or institutional perspectives have often been neglected, although for occupational health and safety (OHS) management, as well as occupational health and safety systems, many questions remain unanswered. Therefore, in the present paper, information and communication technologies (ICT)-enabled mobile work is described taking into account institutional and regulative, as well as company-related, requirements. As the literature-based analysis was able to show, existing regulations cover many aspects of mobile work arrangements but also offer starting points for a more concrete protection of mobile workers. Furthermore, there are challenges regarding the enforcement of regulation. In this regard, new technologies might offer the chance to improve the interactions between institutional and company-related occupational health and safety systems. Additionally, 278 co-funded research projects in Germany were categorized, yielding 18 projects on new ways of work, of which another eleven projects addressed different aspects of mobile work. The project analysis revealed that current research focuses on tools and strategies for designing communication and cooperation. In conclusion, the examination of research trends can be used to generate new knowledge for better OHS management and effective OHS systems.

AbstractThis survey has been performed as part of a wider survey within the Western Balkan Small and Medium Sized Enterprises (SME) Competitiveness Support Project. It presents the current situation of occupational health and safety (OHS) management at 18 SMEs in Kosovo. SMEs in the Republic of Kosovo are facing many difficulties in identifying the real need for interventions, recruiting adequate professional staff to support their activities in OHS. Exposed to an opened market under the regional and international competition, their sustainability has become more difficult and their financial fragility leads very often to the ignorance of OHS issues within their organization.The first objective of this research aimed to understand the OHS contextual factors, barriers and drivers based on the current practice of SMEs in Kosovo. The second objective was to find out if the OHS “ideal intervention process” is applicable to achieve improvements for SMEs in Kosovo. Data collection was expedited through internal documents review, site visits and questionnaires. The statistical data were subject to descriptive analyses and inferential statistics. The findings showed that the contextual factors which influence the intervention process, were of participatory nature, cognitive and physical workplace environment, while the perceived barriers were mainly coming from lack of resources and information. Finally the features of OHS “ideal intervention process” were analyzed and compared for applicability to the SMEs in Kosovo and several interventions in this regards were proposed.

The fourth industrial revolution (I4.0) is expected to increase quality, efficiency, availability, sustainability, the reduction of costs, the demand for energy and environment, and mainly increase the level of occupational health and safety (OHS). New procedures or paradigms of this revolution deflect from already used standards and create an assumption for building the exceptionality of organizations. The main idea of the performed research was to assess how managers in the Slovak industry perceive the readiness of organizations for the implementation of I4.0. The aim of this study, applied in 53 companies, was to assess two areas: the integration level of complex safety into management systems; and the impact of digitalization on OHS. The applied methodology was based on a modified EFQM (European Foundation for Quality Management) exceptionality model. Answers were transformed into numeric figures using a so-called spider web diagram. In the conclusion of this article, there are described interesting differences in the two mentioned areas based on the perception of both top management and the estimation of the readiness degree of the Slovak organizations for I4.0 concept.

Full textAbstract:
A significant part of literature has shown that the adoption of Sustainability and Health-Safety management systems from organizations bears some substantial benefits since such systems (i) create a suitable frame for the sustainable development, implementation and review of the plans and/or processes, necessary to manage occupational health-safety (OHS) in their workplaces and (ii) imply innovative thinking and practices in fields of economics, policy-making, legislation, health and education. To this context, the paper targets at analysing current sustainability and OHSMSs in order to make these issues more comprehend, clear and functional for scholars and practitioners. Therefore, a literature survey has been conducted to map the territory by focusing on two interrelated tasks. The first one includes the presentation of the main International Management Systems (IMS) with focus on Sustainability and OHS (S_OHSMS) topics and the second task depicts a statistical analysis of the literature-review findings (for the years 2006–2017). In particular, the main purposes of the literature research were: (i) the description of key points of OHSMS and sustainability standards, (ii) the comparative analysis of their characteristics, taking into account several settled evaluation-criteria and (iii) the statistical analysis of the survey’s findings, while our study’s primary aim is the reinforcement of OHMSs’ application in any organization. The results evince, that the field of industry (with 28%) and also of the constructions (with 16%), concentrate the highest percentage of OHSMS use. In general, there were only few publications including OHSMSs (referred to various occupational fields) available in the scientific literature (during 2006–2017) but on the other hand, there was a gradually increasing scientific interest for these standards (especially during 2009–2012).

BACKGROUND: Health and safety performance measurements aimed to provide information on the progress and current situation of organizational strategies and activities. OBJECTIVES: We developed a model to determine and select safety key performance indicators in order to assess safety management systems. METHODS: This study has been designed in six steps aiming at defining a model of leading performance indicators (LPIs) and selecting key performance indicators (KPIs) using the AHP method. RESULTS: According to the results analysis, 116 structural and operational indicators were defined based on the components of the OHSAS 18001 management system. For this purpose, 19 structural, 27 operational and 33 active KPIs were selected by AHP and BN techniques. CONCLUSION: Development of LPIs is influenced by various organizational, managerial, and operational factors. LPIs extracted from the components of the OHS-MS deployed in an organization are often passive and cannot show the changes in the safety status of a workplace in a short period. The model presented in this study was designed with an emphasis on extraction of active and operational indicators, as they were capable of detecting performance changes in construction industries.

The concept of occupational health and safety is not defined in Polish law. The only place where such a definition can be found is PN-N-1801:2004. Nevertheless, according to the Act on standardisation, the application of Polish Standards is voluntary. Activities in the field of occupational health and safety should be an integral part of business management. Companies from countries which are members of the European Union, in accordance with Directive 89/391/EEC, are obliged to implement standards related to occupational health and safety. The most commonly used and recognised standard for occupational health and safety management systems, in line with the specifics of each company, is the OHSAS 18001 international management system, while in Poland it is the PN-N-18001 standard. The study examined the scope of OHS at work among Research and Innovation Centre Pro-Akademia employees. The employees were subjected to surveys. The results obtained show that employees appreciate the importance of OHS regulations, but they do not always consciously comply with them. One of the tools that enabled author to prepare this article is analytic method called desk research. Desk Research is a research method that boils down to analyzing the records of available data sources, including in particular their compilation, mutual verification and processing. Such analysis is the basis for drawing conclusions about the examined problem. For example - the effect of the Desk Research analysis proceeded as part of the labor market survey is the diagnosis of the state of the labor market in the studied area, the characteristics of all its component groups as well as a description and verification of the actions taken by the institutions operating within it.

The discussion focuses on the Occupational Health and Safety Management System which was initiated by the International Labour Organization to facilitate the formulation, implementation and evaluation of occupational health and safety interventions at a national policy, sector and organizational level in all countries. It also focuses on Zimbabwe’s occupational health and safety policy, regulatory and institutional framework. The ILO’s OSH-MS 2001 was developed to provide a unique international model, compatible with other management system standards and guides, towards promoting occupational health and safety in a systematic manner. In Zimbabwe, occupational health and safety laws that are applicable to all employers and employees across sectors are enshrined within the Labour Act, Chapter 28.01, and the National Social Security Authority’s Accident Prevention Workers Compensation Scheme Notice No. 68 of 1990. Occupational health and safety management in Zimbabwe is pursued through the International Labour Organization’s Zimbabwe Office, the Ministry of Public Service, Labour and Social Welfare, the National Social Security Authority, and the Zimbabwe Occupational Health and Safety Council, which comprises government, employers and labour unions. It was recommended that Zimbabwe fully adopts the OHS-MS in all sectors, industries and organizations in an adaptive manner. The study also recommended systematic capacity building at a national, sectoral, industrial and organizational level to enhance effective, efficient and adaptive implementation of this tool, and continuous interaction and engagement between the ILO, Ministry of Labour and Social Welfare, EMCOZ, ZCTU and ZFTU for the realization of the highest standards of occupational health and safety in Zimbabwe.

Abstract The issue of social responsibility is one of the most discussed contemporary topics. It is closely related to the financial management of the company. The social area is one of the three main topics integrated in the concept of corporate social responsibility. In addition to the social interactions of the company and its surroundings, there is also included a wide range of internal relations. The largest group within the rage of internal relations consists of employees. Employees’ satisfaction, loyalty, fluctuation, sick leave of employees, as well as accident rate has a direct impact on labour productivity. This has a direct impact on the economic performance of the company. In the Czech Republic, the highest number of accidents and the highest number of fatalities are in the construction industry. The summary of duties related to the occupational health and safety of workers at workplace, given the acronym OHS, is based on legislative regulations. OHS is regulated primarily by the Labour Code and Law. 309/2006 Sb. The standard for occupational health and safety management systems is currently OHSAS 18001. When a company is certified, it is demonstrating an occupational health and safety management at high level and its continuous improvement. This article deals with the measurement of economic performance of enterprises in connection with the implementation of OHSAS certificate 18001. Economic performance is represented by return on equity and based on data obtained from financial statements. Performance measurement is used on 50 enterprises operating in the construction sector in the Czech Republic. The impact of the implementation of the OHSAS certificate on economic performance is quantified mainly by comparison methods and correlation analysis.

Conventionally managed citrus orchards can be modified to incorporate advanced horticultural practices such as higher plant density and efficient water and fertilizer application known as open hydroponics system (OHS) to increase productivity under Huanglongbing (HLB) endemic conditions. A field study was conducted from 2013 to 2018 to evaluate the effect of an OHS on “Ray Ruby” grapefruit (RR) production under HLB-endemic conditions. We tested a combination of different rootstocks [Sour orange (RR/SO) and US-897 (RR/897)], tree planting densities [standard (STD, 358 trees per ha) and high density staggered (HDS, 953 trees per ha)], fertilization methods (dry granular—dry and fertigation—fert), and irrigation systems (double driplines—DD and microsprinkler—MS), arranged in five treatments: RR/SO_STD_dry_MS, RR/SO_HDS_fert_DD, RR/897_HDS_fert_MS, RR/897_HDS_fert_DD, and RR/SO_HDS_fert_MS. All trees were infected by Candidatus Liberibacter asiaticus five years after planting. Trunk diameter and canopy volume increased over time and were higher under RR/SO_STD_dry_MS compared to other treatments. Total fruit number increased in 2016/17 compared to other seasons; however, 65% of fruit were classified as small (<100 mm). Fruit produced under RR/897_HDS_fert_DD had the highest amount (79%) of adequate size fruit (100–117 mm) compared to other treatments. Fruit yield was similar for both rootstocks planted at HDS using DD and MS fertigation, and 67% higher than the standard treatment (RR/SO_STD_dry_MS). Soluble solid contents (SSC), titratable acidity, and SSC-to-titratable acidity ratio were not affected by the treatments. HDS planting resulted in higher fruit yield, irrespective of rootstock and irrigation system, representing an important advance in grapefruit production. Overall, our results demonstrated that production of grapefruit in high-density using OHS can be used by citrus growers who aim to make the best water and fertilizer management under HLB-endemic conditions.

Full textAbstract:
Leaks of hydrocarbon to the atmosphere can be a major facility safety risk and personnel occupational health and safety (OHS) risk for oil and gas producing and processing facilities. Normally closed valves that pass or leak in-line are also a major contributor to product loss and facility risk. Component failures of these types have two common and challenging features: they are hard to find among the tens of thousands of potential leak sources, and the leakage rates either to the atmosphere or in-line can vary from minor to potentially catastrophic. In the past seven to eight years, advanced methods for finding and managing leaks resulting from poor component integrity have been developed. This paper covers some of ATMECO’s accumulated knowledge developed over many leak surveys of both onshore and offshore oil and gas facilities. Typical statistical profiles of leaks from uncontrolled facilities are presented. The types of component failure that lead to leaks are discussed along with probabilistic analyses relating to the next likely failure. Technologies of leak detection are reviewed, highlighting benefits and problems. Also discussed are the prerequisite data capture and management systems needed for a competent, robust and auditable system to manage component integrity. Gas imaging technology is becoming one of the core hydrocarbon leak detection tools and also assists greatly in the analyses of leaks and in providing valuable input to remedial actions. Survey design requirements for continuing and cost-effective component leak risk management are reviewed. Recommendations are provided about the preferred methods and management structures for programs designed to minimise component integrity risks.

It is established that the existing methodological approaches to risk management in occupational health and safety ensure for the implementation of only four of the eight necessary stages (stages of risk evaluation) of the relevant process provided by the PDCA methodology. Mathematical models, which allow to set the relationship between occupational health and safety costs and the risk level, as well as to set the probability of not exceeding the accumulation in the employee of the consequence of certain harmful factors impact and occupational injuries at random during the workshift are substantiated and proposed for use. The main disadvantages of the existing automated systems of risk minimization in occupational health and safety, which are the impossibility of minimizing the negative “human factor” signs and the impossibility of prompt normalization of the parameters of harmful production factors on the employee over time are identified. The automated management system of occupational health and safety, which allows to conduct constant monitoring and prompt correction of parameters of impact on the employee of negative factors within the values set by results of risk evaluation is substantiated and offered for application.

Abstract Objective The study sought to explore online health communities (OHCs) for sexual minority women (SMW) with cancer by conducting computational text analysis on posts. Materials and Methods Eight moderated OHCs were hosted by the National LGBT Cancer Network from 2013 to 2015. Forty-six SMW wrote a total of 885 posts across the OHCs, which were analyzed using Linguistic Inquiry and Word Count and latent Dirichlet allocation. Pearson correlation was calculated between Linguistic Inquiry and Word Count word categories and participant engagement in the OHCs. Latent Dirichlet allocation was used to derive main topics. Results Participants (average age 46 years; 89% white/non-Hispanic) who used more sadness, female-reference, drives, and religion-related words were more likely to post in the OHCs. Ten topics emerged: coping, holidays and vacation, cancer diagnosis and treatment, structure of day-to-day life, self-care, loved ones, physical recovery, support systems, body image, and symptom management. Coping was the most common topic; symptom management was the least common topic. Discussion Highly engaged SMW in the OHCs connected to others via their shared female gender identity. Topics discussed in these OHCs were similar to OHCs for heterosexual women, and sexual identity was not a dominant topic. The presence of OHC moderators may have driven participation. Formal comparison between sexual minority and heterosexual women’s OHCs are needed. Conclusions Our findings contribute to a better understanding of the experiences of SMW cancer survivors and can inform the development of tailored OHC-based interventions for SMW who are survivors of cancer.

Full textAbstract:
PurposeIn China, healthcare services have historically been expensive and difficult to access, with resources being unfairly distributed, often being centralized in large hospitals in major cities. In rural regions, hospitals often suffer from limited supplies, including human capital and equipment. E-health technologies have received significant attention from governments and citizens, with online healthcare communities (OHCs) providing easier communication between patients and doctors. Although doctors play a pivotal role in the success of OHCs, they are often unsure how to attract patients, with limited research focusing on this. The purpose of this paper is to explore how doctors can take initiatives in OHCs, from the joint perspectives of individual effort (i.e. intrapersonal factor) and identity in medical teams (MTs) (i.e. interpersonal factor), based on attribution theory.Design/methodology/approachHierarchical linear regression was conducted on data from 3,170 doctors participating in 865 online MTs, to examine the effects of individual effort and identity in MTs on individual performance. Individual effort included central effort (log-in frequency to OHC) and peripheral effort (articles published on doctors' homepages). Identity in MTs was represented as the identity of team leader and multiple team membership (MTM).FindingsThis study found that the main variables – central and peripheral effort, and leader and MTM identity – all had significant and positive impacts on the service quantity (SQ) of both written and telephone consultations. Although positive effects could be experienced in most conditions that were congruent with the logic of identity theory, the interaction terms demonstrated complex influences. Specifically, leader identity did not moderate the effect of article effort in written consultation, while MTM identity could not moderate the relationship between frequency effort and SQ in telephone-consultation services. Further, the leader identity negatively moderated the relationship between article effort and SQ in telephone consultations. Thus, for doctors with the leader identity, the impact of article effort on SQ was weaker. In summary, both aspects were proved to play important roles in individual SQ.Practical implicationsThis study provides empirical findings through focusing on the SQ of both written and telephone consultations in OHCs, thereby enabling healthcare providers to take initiatives and ultimately improve the efficiency and provision of delivered healthcare services. It is worth mentioning that doctors possessing the identity of team leader should be cautious that the more articles published by them may not lead to envisaged telephone-consultation performance, according to the negative moderating effect of leader identity on the relationship between article effort and SQ during telephone consultations.Originality/valueThis study contributes to the OHC literature by investigating how doctors' efforts and identity in OHCs affect individual performance, based on attribution theory and identity theory. Further, we provide healthcare practitioners with an improved understanding of these dimensions to improve autonomy regarding service provision in OHCs.

Full textAbstract:
The loss of methyl bromide as a soil fumigant and minimal advances in the development and registration of new chemical fumigants has resulted in a resurgence of interest in the application of organic amendments (OAs) for soilborne plant pathogen and plant-parasitic nematode management. Significant progress has been made in the characterization of OAs, application of strategies for their use, and elucidation of mechanisms by which they suppress soilborne pests. Nonetheless, their utility is limited by the variability of disease control, expense, and the logistics of introducing them into crop production systems. Recent advances in molecular techniques have led to significant progress in the elucidation of the role of bacteria and fungi and their metabolic products on disease suppression with the addition of OAs. Biosolarization and anaerobic soil disinfestation, developed to manipulate systems and favor beneficial microorganisms to maximize their impact on plant pathogens, are built on a strong historical research foundation in OAs and the physical, chemical, and biological characteristics of disease-suppressive soils. This review focuses on recent applications of OAs and their potential for the management of soilborne plant pathogens and plant-parasitic nematodes, with emphasis primarily on annual fruit and vegetable production systems.

Full textAbstract:
Studies were conducted in 2010 and 2011 to determine the effect of herbicide-based Palmer amaranth management systems in ‘Covington' sweetpotato. Treatments consisted of three herbicide application times. Pretransplant applications were flumioxazin at 107 g ai ha−1, fomesafen at 280 g ai ha−1, flumioxazin at 70 g ha−1plus pyroxasulfone at 89 g ai ha−1, or no herbicide. A second herbicide application was applied within 1 d after transplanting (DAP) and consisted ofS-metolachlor at 800 g ai ha−1, clomazone at 630 g ai ha−1, or no herbicide. Two weeks after planting (WAP) plots receivedS-metolachlor at 800 g ha−1, metribuzin at 140 g ai ha−1, a tank mix ofS-metolachlor at 800 g ha−1plus metribuzin at 140 g ha−1, hand-weeding followed by (fb)S-metolachlor at 800 g ha−1, or no herbicide. Crop tolerance, Palmer amaranth control, and sweetpotato yield in systems containing fomesafen pretransplant were similar to flumioxazin-containing systems. Systems containing flumioxazin plus pyroxasulfone pretransplant resulted in increased crop stunting and decreased sweetpotato yield in 2010, compared with systems containing flumioxazin or fomesafen, but were similar to systems with flumioxazin or fomesafen in 2011. In 2010, systems containingS-metolachlor applied within 1 DAP resulted in increased sweetpotato injury, similar Palmer amaranth control, and reduced no. 1, jumbo, and total sweetpotato yield, compared with systems with clomazone. In 2011, systems containing clomazone were more injurious to sweetpotato than systems receivingS-metolachlor, but Palmer amaranth control and sweetpotato yield were similar. Systems containing metribuzin 2 WAP resulted in increased sweetpotato injury and Palmer amaranth control (in 2010) but similar no. 1 and total sweetpotato yields, compared with systems containingS-metolachlor at 2 WAP. Hand-weeding fbS-metolachlor provided greater Palmer amaranth control and no. 1 sweetpotato yield than did systems ofS-metolachlor without a preceding hand-weeding event in 2010.

Full textAbstract:
Within the management of urban disasters, geo-information systems (GIS) are used in any of the phases of mitigation, preparedness, response and recovery as most of the required data have a spatial component. Examples of GIS-based decision support systems on mitigation are found in simulation models of floods and earthquakes. In the preparation phase all kinds of spatial observations and models can be used to predict which areas will be threatened. To prepare for adequately responding in case of an actual disaster, these systems are capable of developing realistic scenarios that are used within training and virtual reality (VR) systems. During the actual response phase geo-information is used intensively: for getting an impression of the environment, for routing, for obtaining up-to-date information about the actual situation, etc. In the recovery phase, there is often a high public and political interest to judge the situation - comparing the pre- and post-disaster situation - and to set priorities for the rebuilding. Despite this potential of GIS-based support for urban disaster management, the use of these systems or even the utilisation of geo-information itself is still very limited in countries in Africa, Asia and Latin America. The emergency management is usually done with paper maps that are seldom up-to-date. Useful systems to support decision makers in any of the phases of disaster management are nearly completely lacking. To improve the work of decision makers and rescue teams, different premises have to be archived in relation to: meta-information to provide insight on the availability and usefulness of the geo-information itself, the technical equipment of the rescue teams (i.e. communication devices and field computers), and the up-to-date information from the affected areas (images, observations, reports). This paper suggests a framework for “urban and urgent” disaster management to facilitate the work of police forces, fire departments, ambulances and government coordinators in disaster situations by extending and improving the utilisation of geo-information. Within a pre-disaster situation, geo-information support management further can assist planning for prevention and mitigation.

Full textAbstract:
The role of the endocannabinoid/endovanilloid (EC/EV) system in bone metabolism has recently received attention. Current literature evidences the modulation of osteoclasts and osteoblasts through the activation or inhibition of cannabinoid receptors in various pathological conditions with secondary involvement of bone tissue. However, this role is still unclear in primary bone diseases. Paget’s disease of the bone (PDB) could be considered a disease model for analyzing the role of the EC/EV system on osteoclasts (OCs), speculating the potential use of specific agents targeting this system for managing metabolic bone disorders. The aim of the study is to analyze OCs expression of EC/EV system in patients with PDB and to compare OCs activity between this population and healthy people. Finally, we investigate whether specific agents targeting EC/EV systems are able to modulate OCs activity in this metabolic bone disorder. We found a significant increase in cannabinoid receptor type 2 (CB2) protein expression in patients with PDB, compared to healthy controls. Moreover, we found a significant reduction in multi-nucleated tartrate-resistant acid phosphatase (TRAP)–positive OCs and resorption areas after treatment with JWH-133. CB2 could be a molecular target for reducing the activity of OCs in PDB, opening new therapeutic scenarios for the management of this condition.

Full textAbstract:
Electric vehicles (EVs) promote many advantages for distribution systems such as increasing efficiency and reliability, decreasing dependence on non-endogenous resources, and reducing pollutant emissions. Due to increased proliferation of EVs and their integration in power systems, management and operation of distribution systems (ODS) is becoming more important. Recent studies have shown that EV can increase power grid flexibility since EV owners do not use them for 93–96% of the daytime. Therefore, it is important to exploit parking time, during which EVs can act either as a load or distributed storage device, to maximize the benefit for the power system. Following a survey of the current state-of-the-art, this work studies the impact of EV charging on the load profile. Since renewable energy resources (RES) play a critical role in future distribution systems the current case study considered the presence of RES and their stochastic nature has been modeled. The study proceeds with analyzing EV owners’ driving habits, enabling prediction of the network load profile. The impact of: EV charging modes (i.e., controlled and uncontrolled charging), magnitude of wind and photovoltaic (PV) generation, number of EVs (penetration), and driving patterns on the ODS is analyzed.

The current information system is the backbone of most companies or agencies. Currently there are various types of information systems including "transaction processing systems (TPS), office automation systems (OAS), knowledge work systems (KWS), management information systems (MIS), decision support systems (DSS), expert systems, groups decision support systems (GDSS), computer support collaborative work systems (CSCW), and executive support systems (ESS) ". Of the various types of information systems that are currently available decision support systems are widely used as aids in making decisions. For this reason, in this study, a study was conducted with a method that can be used in a decision support system. From the study conducted there are three decision support system methods that are often used, namely simple additive weighting (SAW), analytic hierarchy process (AHP), and simple multi attribute rating technique (SMART). The third method is a method that has a weighting value and criteria in the calculation process

Full textAbstract:
The optimal management of multiple chiller systems calls for the solution of the so-called optimal chiller loading (OCL) problem. Due to the interplay of continuous and logical constraints, OCL is an NP-hard problem, so that a variety of heuristic algorithms have been proposed in the literature. Herein, an algorithm for its exact solution, named X-OCL, is developed under the assumption that the chillers’ power consumption curves are quadratic. The proposed method hinges on a decomposition of the solution space so that the overall OCL problem is decomposed to a set of equality constrained quadratic programming problems that can be solved in closed form. By applying the new X-OCL solver to well known case studies, we assess and compare the performances of several literature algorithms, highlighting also some errors in the published results. Moreover, X-OCL is used to design a greedy optimal chiller sequencing (OCS) solver, called X-OCS. The X-OCS is tested on two literature benchmarks and on the model of the heating, ventilation and air-conditioning (HVAC) system of a semiconductor plant, over a two-year period. The performances of X-OCS are remarkably close to the theoretical optimal performance.

Comparative studies have usually shown higher yields in conventional cropping systems (CCS) than in organic cropping systems (OCS). By utilizing a long-term field experiment on silt soil with 18 years of cropping history (19821999), including three OCSs and one CCS, we studied if this is true also for strawberry. The strawberry experiment was conducted in 20002002. The experiment had one CCS (A) and three OCSs (B,C,D). The impact of pre-planting peat amendment was also studied. The degree of overwintering, fruit yields, yield components and some soil nutrients were determined. Total and marketable fruit yields were estimated using a peduncle analysis based on weights of fruits of different orders in the peduncle, numbers of healthy and injured fruits in the peduncle and the number of peduncles per plant. The shoot growth, total and marketable fruit yields, as well as all yield components estimated were significantly higher in the OCS rotation D than in the CCS rotation A. The peat amendment, but not the cropping system, decreased the percentage of strawberry plants suffering from or killed by winter damage. However, peat amendment did not affect yield. The cropping system had no impact on soil pH, or the amount of extractable calcium, magnesium and nitrate. Extractable phosphorus and potassium were higher and soil organic carbon (Corg) slightly higher in the OCS than in the CCS. The peat amendment increased Corg by 2%. The amounts of extractable nutrients in soil were not a limiting factor for strawberry growth and yield as they were of sufficient levels both in CCS and OCS. It remains unclear whether the higher yield in the OCS was due to a long-term cropping history or to a short-term effect of composted manure, or to a combination of these two. The importance of soil organic management in strawberry production is emphasized.;

The study was conducted to investigate the prevalence of obstetrical disorders (ODs) of 975 dairy cows in relation to genotype, age, parity, housing system, feed quality, rearing system, breeding systems and professional training of owners at Rajshahi, Bangladesh from the period 1 January, 2009 to 31 December, 2009. Extensive survey was conducted in 15 areas of Rajshahi and in each area 65 dairy cows were selected randomly. Individual farmers were interviewed to obtain information about ODs of dairy cows viz; abortion, dystocia, retained placenta, uterine and vaginal prolapse. Out of 975 cows, 117 animals were found to be affected by various ODs showing an overall prevalence of 12.00%. Among the ODs, retained placenta showed the highest prevalence (4.10%) followed by abortion (4.0%), dystocia (2.77%), uterine prolapse (0.66%) and vaginal prolapse (0.51%). The observation of genotype wise ODs in cows revealed that the maximum prevalence was in the Local × Friesian (15.97%), followed by Local (14.68%) and Local × Jersey (9.80%) while the minimum prevalence was in the Local × Sahiwal (5.55%). The age group (>48 months) showed highest prevalence (20.25%) of ODs while the lowest (6.66%) was recorded in < 24 months of age in cows. Parity-wise splitting of the data showed that the maximum prevalence of ODs was in the >5th parity (15.35%) and minimum in the 1st parity (6.15%) of cows. The traditional rearing and farming system revealed highest (17.26%) and lowest (8.51%) prevalence of ODs in cows, respectively. The quality of feed had effect on prevalence of ODs in dairy cows (P<0.05). The ODs were also increased in artificial inseminated cows (12.59%) than naturally service groups (11.90%). The training of farmers had significant effect among the non trained and trained groups for the occurrence of ODs in cows. The study revealed relatively low prevalence of reproductive disorders in cows at Rajshahi compare to other regions of Bangladesh, might be due to better management practices adopted by the farmers and efficient veterinary services as well as awareness among farmers.Asian J.

Aggregation of distributed generations (DGs) along with energy storage systems (ESSs) and controllable loads near power consumers has led to the concept of microgrids. However, the uncertain nature of renewable energy sources such as wind and photovoltaic generations, market prices and loads has led to difficulties in ensuring power quality and in balancing generation and consumption. To tackle these problems, microgrids should be managed by an energy management system (EMS) that facilitates the minimization of operational costs, emissions and peak loads while satisfying the microgrid technical constraints. Over the past years, microgrids’ EMS have been studied from different perspectives and have recently attracted considerable attention of researchers. To this end, in this paper a classification and a survey of EMSs has been carried out from a new point of view. EMSs have been classified into four categories based on the kind of the reserve system being used, including non-renewable, ESS, demand-side management (DSM) and hybrid systems. Moreover, using recent literature, EMSs have been reviewed in terms of uncertainty modeling techniques, objective functions (OFs) and constraints, optimization techniques, and simulation and experimental results presented in the literature.

This paper addresses opportunities available for meeting sustainability objectives in building construction by using the conceptual alignments of Open Building and LEED™ Rating. These two systems utilize hierarchical, scalar categorizations to structure issues of design as a set of nested constructs and function as methodologies for affecting both problem definition and the management of strategic design process. Each system addresses the distribution of control in the design decision−making process as a positioning of decisions in space and time. Establishing the correlation of the two systems can facilitate the conversation among all participants involved in the origination, construction, use, and management of buildings−and their systems−as they seek to assure the sustainability of what they design, build, and use.

Abstract BACKGROUND AND IMPORTANCE Chronic subdural hematoma (cSDH) is a common neurosurgical pathology with a projected increase in prevalence as the elderly population grows. Traditional treatment for cSDH involves burr hole drainage or craniotomy with or without a subdural drain. This case describes a novel irrigation and drainage protocol using IRRAflow dual-lumen catheter system that utilizes early irrigation and measurement of the net fluid output to improve postoperative outcomes. CLINICAL PRESENTATION A 75-yr-old male presented to the emergency department with 2 wk of progressive dizziness, headache, confusion, and left-sided weakness over the past week. Computed tomography (CT) of the head showed 25-mm-thick, right-sided cSDH with 7 mm of right-to-left midline shift. The patient was taken to the operating room for right-sided craniotomy for subdural hematoma evacuation with placement of IRRAflow irrigating drain in the subdural space. The IRRAflow drain irrigated at 100 cc/h for 23 h with net output consistently greater than irrigation rate. Head CT the following day showed a progressive decrease in subdural collection. The patient was discharged on postoperative day 2 and had complete resolution of his neurological symptoms by postoperative day 11. CONCLUSION As cSDHs become more prevalent in the aging population, development of improved management strategies is imperative. This report describes the use of an IRRAflow dual-lumen catheter with a novel protocol consisting of a high rate of irrigation but net fluid output, which led to rapid recovery and resolution of neurological deficits in a patient with a cSDH.

Full textAbstract:
Five studies were conducted at Clayton, Rocky Mount, and Lewiston-Woodville, NC, in 2001 and 2002, to evaluate weed management, crop tolerance, and yield in strip- and conventional-tillage glyphosate-resistant cotton. Cotton was treated with two glyphosate formulations; glyphosate-IP (isopropylamine salt) or glyphosate-TM (trimethylsulfonium salt), early postemergence (EPOST) alone or in a mixture withS-metolachlor. Early season cotton injury was minimal (3%) with either glyphosate formulation alone or in mixture withS-metolachlor. Weed control and cotton yields were similar for both glyphosate formulations. The addition ofS-metolachlor to either glyphosate formulation increased control of broadleaf signalgrass, goosegrass, large crabgrass, and yellow foxtail 14 to 43 percentage points compared with control by glyphosate alone.S-metolachlor was not beneficial for late-season control of entireleaf morningglory, jimsonweed, pitted morningglory, or yellow nutsedge. The addition ofS-metolachlor to either glyphosate formulation increased control of common lambsquarters, common ragweed, Palmer amaranth, smooth pigweed, and velvetleaf 6 to 46 percentage points. The addition of a late postemergence-directed (LAYBY) treatment of prometryn plus MSMA increased control to greater than 95% for all weed species regardless of EPOST treatment, and control was similar with or withoutS-metolachlor EPOST. Cotton lint yield was increased 220 kg/ha with the addition ofS-metolachlor to either glyphosate formulation compared with yield from glyphosate alone. The addition of the LAYBY treatment increased yields 250 and 380 kg/ha for glyphosate plusS-metolachlor and glyphosate systems, respectively.S-metolachlor residual activity allowed for an extended window for more effective LAYBY application to smaller weed seedlings instead of weeds that were possibly larger and harder to control.

Abstract BACKGROUND Deep brain stimulation (DBS) is a treatment modality increasingly utilized in the management of neurological and psychiatric conditions. Neurosurgical technical considerations and contraindications have yet to be thoroughly characterized in the literature. The patient population for DBS includes many elderly patients with multiple comorbidities who require treatments and investigations that expose them to electromagnetic fields of varying strengths and durations, including other implanted electromodulatory devices. OBJECTIVE To determine if clinically significant interference arises between DBS and cardiac pacemaker systems. METHODS Here we audited 8 patients, mean age 72, with cardiac pacemakers and DBS implanted from 2007 to 2015. We investigated details of their neurological and electrocardiological treatment and progress and sought evidence for interference between the two systems. RESULTS We found no evidence of DBS dysfunction, and only one case of abnormal pacemaker interrogation 2 yr post-DBS implantation was found, which was thought to be secondary to a medication issue rather than neuromodulation interference. CONCLUSION Our research reassures the clinician that pacemakers and DBS systems do not appear to affect one another and provides guidance on minimizing possibility of this.

Full textAbstract:
Purpose Literature highlights the impact of culture on managerial processes in general and the performance measurement system (PMS) in particular. However, understanding how organizational culture (OC) influences the PMS remains a challenge, especially in SMEs as in these companies the studies are very limited. The purpose of this paper is to investigate how OC influences PMSs in manufacturing SMEs. Design/methodology/approach To achieve the above purpose, a case study approach has been adopted. Four manufacturing SMEs with heterogeneous OC were investigated by means of companies’ documents reviews, participant observations and semi-structured interviews. A conceptual framework based on the competing value framework proposed by Cameron and Quinn (1999) and the PMS typology proposed by Garengo (2009) has been used to investigate the impact of OC on PMS. Findings According to the results, OC has a huge impact on PMS in manufacturing SMEs. The dimensions of “internal/external focus” influence strategy formalization, monitoring of the external environment and performance review. The “flexibility/control” dimensions influence the adoption of the balanced (or unbalanced) set of performance measures a company uses. Originality/value This paper contributes to clarifying how OC influences PMSs in manufacturing SMEs. Moreover, the study of interplay between flexibility/control dimensions and internal/external dimensions supports the identification of three theoretical propositions and four PMS types related to the four different OCs identified by Cameron and Quinn (1999).

Aim. The presented study aims to illustrate that by making use of industrial localization tools, the one business space (OBS) system solves the problem of replacing global value chains with local ones, leading to positive innovation-oriented structural sectoral transformations and the development of the economy’s export-oriented potential.Tasks. The authors examine the types of localization and the strategy of an automotive company for the formation and operation of regional sectoral OBS systems over time (2012–2019) through the example of the petrochemical and metalworking industries in the Republic of Tatarstan, showing the possibility of transforming industrial localization into import substitution.Methods. This study uses modern achievements of the theory of knowledge, innovation-driven development, methods of systematization and analysis, empirical research, including the collection, examination, and generalization of practical material, forecasting, analysis of the works of Russian and foreign scientists in the field of technological and non-technological activities, principles of change management.Results. By using industrial localization tools for the formation of multiple value chains in the host region within the framework of a partnership, it is possible to create an industry-wide vertically integrated management system for the innovation-driven development of automotive components production at the regional level. Horizontal integration into the social, scientific, and educational spheres of regions is a mandatory aspect for the development of such systems, which leads, among other things, to the development of scientific potential while also improving the quality of human capital. Within the framework of OBS, regional value chains are formed — from the extraction of raw materials to the final assembly of the car — with a total average annual turnover of 25 billion rubles. A significant number of jobs are created, as well as new automotive components and materials with unique properties for the Russian industry. This facilitates the production of Russian analogues in the interests of other OEMs and consumers, as well as the transformation of industrial localization into import substitution. In addition, products of localization are beginning to replace their analogues in the global supply chains of automotive components, thereby developing the export-oriented component of the regional economy.Conclusions. In certain cases, industrial localization in OBS systems is transformed into import substitution, significantly increasing the efficiency of industrialization in the region and the country as a whole.

ABSTRACTStreptococcus suis, a global zoonosis of pigs, shows regional differences in the prevalence of human-associated disease for Asian and non-Asian countries. The isolation rates and diversities ofS. suison tonsils of healthy slaughter pigs in China and the United Kingdom were studied for effects of geography, temperature, pig age, and farm type. Isolates underwent analysis of molecular serotype and multilocus sequence type and virulence-associated genotyping. Although we found no significant difference in positive isolation rates between Chinese and UK farms, the prevalences of serotypes previously associated with human disease were significantly greater in the Chinese collection (P= 0.003). A significant effect of temperature was found on the positive isolation rate of the Chinese samples and the prevalence of human disease-associated serotypes in the UKS. suispopulation (China,P= 0.004; United Kingdom,P= 0.024) and on the prevalence of isolates carrying key virulence genes in China (P= 0.044). Finally, we found marked diversity amongS. suisisolates, with statistically significant temperature effects on detection of multiple strain types within individual pigs. This study highlighted the high carriage prevalence and diversity ofS. suisamong clinically healthy pig herds of China and the United Kingdom. The significant effect of temperature on prevalence of isolation, human disease-associated serotypes, and diversity carried by individual pigs may shed new light on geographic variations in humanS. suis-associated disease.IMPORTANCEStreptococcus suisis a global zoonotic pathogen and also a normal colonizer mainly carried on the tonsil of pigs. Thus, it is important to study the effect of environmental and management-associated factors on theS. suispopulations in clinically healthy pigs. In this research, we investigated the similarities and differences between theS. suispopulations obtained from different pig ages, seasons, and farm management systems and discovered the relationship between high climatic temperature and the prevalence ofS. suis.
