The Indonesia Nuclear Energy Act no. 10 of 1997 clearly stated that Nuclear Energy Regulatory Agency (BAPETEN) is the Nuclear Regulatory Body. This is the legal basis of BAPETEN to perform regulatory functions on the use of nuclear energy in Indonesia, including regulation, authorisation, inspection and enforcement. The Independent regulatory functions are stipulated in Article 4 and Article 14 of the Nuclear Energy Act no. 10 (1997) which require the government to establish regulatory body that is reporting directly to the president and has responsibility to control of the use of nuclear energy. BAPETEN has been start fully its functioning on January 4, 1999. In it roles as a regulatory body, the main aspect that continues and always to be developed is the safety culture. One of the objectives of regulatory functions is “to increase legal awareness of nuclear energy of the user to develop safety culture” (Article 15, point d), while in the elucidation of article 15 it is stipulated that “safety culture is that of characteristics and attitudes in organizations and individual that emphasise the importance of safety”.

The Canadian Nuclear Safety Commission (CNSC) regulates the use of nuclear energy and materials to protect health, safety, security and the environment, and to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public. In the late 1990s, the CNSC conducted research into an Organization and Management (O&M) assessment method. Based on this research the CNSC conducted O&M assessments at all Canadian nuclear power plants and conducted additional assessments of nuclear research and uranium mine and mill operations. The results of these assessments were presented to licencees and used to inform their ongoing actions related to safety culture. Additional safety culture outreach and oversight activities provided licencees with opportunities to develop effective safety culture assessment methods, to share best practices across industry, and to strive for continual improvement of their organizations. Recent changes to the Canadian Standards Association (CSA) management system standard have resulted in the inclusion of requirements associated to safety culture and human performance. Representatives from several sectors of Canada’s nuclear industry, as well as participation from regulators such as the CNSC took part to the development of this consensus standard. Specifically, these requirements focus on monitoring and understanding safety culture, integrating safety into all of the requirements of the management system, committing workers to adhere to the management system and supporting excellence in workers’ performance. The CNSC is currently developing a regulatory document on safety culture which includes key concepts applicable to all licencees and specific requirements related to self-assessment, and additional guidance for nuclear power plants. Developing a regulatory document on safety culture requires consultation and fact finding initiatives at

Improvements of the Regulatory Framework for Nuclear Installations in the Areas of Human and Organizational Factors and Safety Culture

Tronea, M.; Ciurea, C.

2016-01-01

The paper presents the development of regulatory requirements in the area of human and organizational factors taking account of the lessons learned from major accidents in the nuclear industry and in particular of the factors that contributed to the Fukushima Daiichi accident and the improvement of the regulatory oversight of nuclear safety culture. New requirements have been elaborated by the National Commission for Nuclear Activities Control (CNCAN) on the nuclear safety policy of licencees for nuclear installations, on independent nuclear safety oversight, on safety conscious work environment and on the assessment of nuclear safety culture. The regulatory process for the oversight of nuclear safety culture within licencees’ organizations operating nuclear installations and the associated procedure and guidelines, based on the IAEA Safety Standards, have been developed in 2010-2011. CNCAN has used the 37 IAEA attributes for a strong safety culture, grouped into five areas corresponding to safety culture characteristics, as the basis for its regulatory guidelines providing support to the reviewers and inspectors, in their routine activities, for recognising and gathering information relevant to safety culture. The safety culture oversight process, procedure and guidelines are in process of being reviewed and revised to improve their effectiveness and to align with the current international practices, using lessons learned from the Fukushima Daiichi accident. Starting with July 2014, Romania has a National Strategy for Nuclear Safety and Security, which includes strategic objectives, associated directions for action and concrete actions for promoting nuclear safety culture in all the organizations in the nuclear sector. The progress with the implementation of this strategy with regard to nuclear safety culture is described in the paper. CNCAN started to define its own organizational culture model and identifying the elements that promote and support safety

Regulatory assessment of safety culture in nuclear organisations - current trends and challenges

Tronea, M.

2010-01-01

The paper gives an overview of the current practices in the area of regulatory assessment of safety culture in nuclear organisations and of the associated challenges. While the assessment and inspection procedures currently in use by regulatory authorities worldwide are directed primarily at verifying compliance with the licensing basis, there is a recognised need for a more systematic approach to the identification, collection and review of data relevant to the safety culture in licensees' organisations. The paper presents a proposal for using the existing regulatory inspection practices for gathering information relevant to safety culture and for assessing it in an integrated manner. The proposal is based on the latest requirements and guidance issued by the International Atomic Energy Agency (IAEA) on management systems for nuclear facilities and activities, particularly as regards the attributes needed for a strong nuclear safety culture.

ILK statement about the regulatory authorities' perception of operators' self-assessment of safety culture

International Nuclear Information System (INIS)

2005-01-01

Over the past few years, German licensing and supervisory authorities have devoted increasing attention to safety management and safety culture issues. At present, German plant operators are introducing systems for self-assessment of the safety culture in their plants, such as the Safety Culture Assessment System developed by VGB Power Tech (VGB-SBS). In its statement, the International Committee on Nuclear Technology (ILK) addresses an effective approach of the authorities in evaluating the self-assessment of safety culture conducted by operators. ILK proposes a total of ten recommendations for evaluating the self-assessment system of the operators by the authority. The regulatory authorities should see to it that the operators establish a self-assessment system for aspects of organization and personnel, and use it continuously. The measures derived from this self-assessment by the operators, and the reasons underlying them, should be discussed with the authorities. In addition to the operators, also the regulatory authorities and the technical expert organizations commissioned by them should carry out self-assessments of their respective supervisory activities, taking into account also special events, such as changes in government, and develop appropriate programs of measures to be taken. In evaluating safety culture, the regulatory authorities should strive to support the activities of operators in improving their safety culture. A spirit of mutual confidence and cooperation should exist between operators and authorities. The recommendations expressed in the statement deliberately leave room for detailed implementation by the parties concerned. (orig.)

Regulatory Oversight of Safety Culture in Finland: A Systemic Approach to Safety

2016-01-01

In Finland the Radiation and Nuclear Safety Authority STUK specifies detailed regulatory requirements for good safety culture. Both the requirements and the practical safety culture oversight activities reflect a systemic approach to safety: the interconnections between the technical, human and organizational factors receive special attention. The conference paper aims to show how the oversight of safety culture can be integrated into everyday oversight activities. The paper also emphasises that the scope of the safety culture oversight is not specific safety culture activities of the licencees, but rather the overall functioning of the licence holder or the new build project organization from safety point of view. The regulatory approach towards human and organizational factors and safety culture has evolved throughout the years of nuclear energy production in Finland. Especially the recent new build projects have highlighted the need to systematically pay attention to the non-technical aspects of safety as it has become obvious how the HOF issues can affect the design processes and quality of construction work. Current regulatory guides include a set of safety culture related requirements. The requirements are binding to the licence holders and they set both generic and specific demands on the licencee to understand, monitor and to develop safety culture of their own organization but also that of their supplier network. The requirements set for the licence holders has facilitated the need to develop the regulator’s safety culture oversight practices towards a proactive and systemic approach.

Regulatory oversight of safety culture in nuclear installations - New IAEA developments

Ms. Anne Kerhoas described the IAEA work on guidance for regulatory oversight of safety culture. She summarised the various IAEA, OECD/NEA and ANS meetings that have been held on the topic between 1995 and 2011. The IAEA has carried out two recent projects with the Bulgarian and Romanian regulatory bodies to develop a safety culture oversight program. The work was funded by the Norwegian government and has involved 30 experts from 17 different countries. Draft guidance for regulators on how to monitor licensee safety culture has also been produced (IAEA-TECDOC-DD1070). The document is intended to provide practical guidance on oversight strategies and is applicable to a wide range of nuclear installations, including nuclear power plants, fuel cycle facilities, research reactors and waste management facilities. A number of principles for regulatory oversight of safety culture were summarised. For example, the primary responsibility for safety remains with the licensee, safety culture oversight should be performed at all stages of the life cycle of the nuclear installation, and multiple data collection methods should be used. The overall approach to safety culture described in the draft IAEA Tech doc includes a range of approaches to build up a meaningful picture of the licensee's safety culture. These include interviews, observations, review of documents, review of events, discussions and surveys. The importance of ongoing discussion with the licensee throughout the process to develop a deeper shared understanding of issues was emphasised. The results of the Chester 2 workshop will be used as an input to finalization of the draft Tech Doc

Assessment of regulatory effectiveness. Peer discussions on regulatory practices

International Nuclear Information System (INIS)

1999-09-01

This report arises from the seventh series of peer discussions on regulatory practices entitled 'Assessment of Regulatory Effectiveness'. The term 'regulatory effectiveness' covers the quality of the work and level of performance of a regulatory body. In this sense, regulatory effectiveness applies to regulatory body activities aimed at preventing safety degradation and ensuring that an acceptable level of safety is being maintained by the regulated operating organizations. In addition, regulatory effectiveness encompasses the promotion of safety improvements, the timely and cost effective performance of regulatory functions in a manner which ensures the confidence of the operating organizations, the general public and the government, and striving for continuous improvements to performance. Senior regulators from 22 Member States participated in two peer group discussions during March and May 1999. The discussions were focused on the elements of an effective regulatory body, possible indicators of regulatory effectiveness and its assessment. This report presents the outcome of these meetings and recommendations of good practices identified by senior regulators, which do not necessarily reflect those of the governments of the nominating Member States, the organizations they belong to, or the International Atomic Energy Agency. In order to protect people and the environment from hazards associated with nuclear facilities, the main objective of a nuclear regulatory body is to ensure that a high level of safety in the nuclear activities under its jurisdiction is achieved, maintained and within the control of operating organizations. Even if it is possible to directly judge objective safety levels at nuclear facilities, such safety levels would not provide an exclusive indicator of regulatory effectiveness. The way the regulatory body ensures the safety of workers and the public and the way it discharges its responsibilities also determine its effectiveness. Hence the

Nuclear Regulatory Systems in Africa: Improving Safety and Security Culture Through Education and Training

International Nuclear Information System (INIS)

Kazadi Kabuya, F.

2016-01-01

The purpose of this paper is to address the important issue of supporting safety and security culture through an educational and training course program designed both for regulatory staff and licensees. Enhancing the safety and security of nuclear facilities may involve assessing the overall effectiveness of the organization's safety culture. Safety Culture implies steps such as identifying and targeting areas requiring attention, putting emphasis on organizational strengths and weaknesses, human attitudes and behaviours that may positively impact an organization's safety culture, resulting in improving workplace safety and developing and maintaining a high level of awareness within these facilities. Following the terrorist attacks of September 11, 2001, international efforts were made towards achieving such goals. This was realized through meetings, summits and training courses events, with main aim to enhance security at facilities whose activities, if attacked, could impact public health and safety. During regulatory oversight inspections undertaken on some licensee's premises, violations of security requirements were identified. They mostly involved inadequate management oversight of security, lack of a questioning attitude, complacency and mostly inadequate training in both security and safety issues. Using training and education approach as a support to raise awareness on safety and security issues in the framework of improving safety and security culture, a tentative training program in nuclear and radiological safety was started in 2002 with the main aim of vulgarizing the regulatory framework. Real first needs for a training course program were identified among radiographers and radiologists with established working experience but with limited knowledge in radiation safety. In the field of industrial uses of radiation the triggering events for introducing and implementing a training program were: the loss of a radioactive source in a mining

Fassmann, W.; Beck, J.; Kopisch, C.

2016-01-01

Need for methods to assess licencees’ safety culture has been recognised since the Chernobyl accident. Several conferences organized by IAEA and OECD-NEA stated the need for regulatory oversight of safety culture and for suitable methods. In 2013, IAEA published a Technical Document (TECDOC 1707) on the process of safety culture oversight by regulatory authorities which leaves much room for regulators’ ways of performing safety culture oversight. In response to these developments, the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) as the federal regulatory body commissioned GRS in 2011 to develop a practical guidance for assessing licencees’ safety culture in the process of regulatory oversight. This research and development project was completed just recently. The publicly available documentation comprises a shorter guidance document with the indispensable information for an appropriate, practical application and a report with more detailed information about the scientific basis of this guidance. To achieve best possible adaptation to regulators’ needs, GRS asked members of the regulatory authority of Baden-Wuerttemberg (one of the federal states of Germany) for comments on a draft of the guidance which was then finalised by duly considering this highly valuable and favorable feedback. Decisions regarding future use rest with German regulatory authorities.

Improving nuclear regulatory effectiveness

International Nuclear Information System (INIS)

2001-01-01

Ensuring that nuclear installations are operated and maintained in such a way that their impact on public health and safety is as low as reasonably practicable has been and will continue to be the cornerstone of nuclear regulation. In the past, nuclear incidents provided the main impetus for regulatory change. Today, economic factors, deregulation, technological advancements, government oversight and the general requirements for openness and accountability are leading regulatory bodies to review their effectiveness. In addition, seeking to enhance the present level of nuclear safety by continuously improving the effectiveness of regulatory bodies is seen as one of the ways to strengthen public confidence in the regulatory systems. This report covers the basic concepts underlying nuclear regulatory effectiveness, advances being made and future requirements. The intended audience is primarily nuclear safety regulators, but government authorities, nuclear power plant operators and the general public may also be interested. (author)

Strengthening Regulatory Competence in a Changing Nuclear Regulatory Environment

International Nuclear Information System (INIS)

Illizastigui, P.F.

2016-01-01

The paper addresses the approach followed by the Cuban National Center for Nuclear Safety for the management of current and new competences of its regulatory staff with the aim of allowing those staff to effectively fulfill their core regulatory functions. The approach is realized through an Integrated System for Competence Building, which is based on the IAEA recommendations, shown to be effective in ensuring the necessary competence in the relevant areas. In the author’s opinion, competence of the regulatory staff in the area of human and organizational factors is of paramount importance and needs to be further strengthened in order to be able to assess safety performance at the facilities and detect early signs of deteriorating safety performance. The former is defined by the author as the core regulatory function “Analysis” which covers the entire spectrum of assessment tasks carried out by the regulatory staff to: a) detect declining safety performance, b) diagnose latent weaknesses (root causes) and c) make effective safety culture interventions. The author suggests that competence associated with the fulfillment of the analysis function is distinctly identified and dealt with separately in the current system of managing regulatory competence.

Lars Axelsson presented SSM progress on oversight of LMfS/SC since the Chester 1 Workshop in 2007. Current SSM approaches for safety culture oversight include targeted safety management and safety culture inspections, compliance inspections which cover aspects of safety management/safety culture and multi-disciplinary team inspections. Examples of themes for targeted inspections include management of ambiguous operational situations or other weak signals, understanding of and attitudes to Human Performance tools, the Safety Department's role and authority and Leadership for safety. All regulatory activities provide inputs for the SSM yearly safety evaluation of each licensee. A form has been developed to capture safety culture observations from inspections and other interactions with licensees. Analysis will be performed to identify patterns and provide information to support planning of specific Safety Culture activities. Training has been developed for regulatory staff to enhance the quality of regulatory interventions on safety culture. This includes a half-day seminar to provide an overview of safety culture, and a workshop which provides more in-depth discussion on cultural issues and how to capture those during regulatory activities. Future plans include guidance for inspectors, and informal seminars on safety culture with licensees

Hematopoietic regulatory factors produced in long-term murine bone marrow cultures and the effect of in vitro irradiation

1984-01-01

The nature of hematopoietic regulatory factors elaborated by the adherent (stromal) cells of long-term murine bone marrow cultures and the effect of in vitro stromal irradiation (XRT) on the production of these factors was investigated. Using an in situ stromal assay it was possible to demonstrate stromal elaboration of at least two colony-stimulating activities, ie, granulocyte/macrophage colony-stimulating activity (G/M-CSA) and megakaryocyte colony-stimulating activity (Meg-CSA). Exposure of the stroma to XRT resulted in dose-dependent elevations of both activities that correlated inversely with total myeloid cell mass. Mixture experiments that combined control and irradiated stroma revealed that the hematopoietically active control stroma could block detection of XRT-related G/M-CSA elevations. Antiserum directed against purified L cell colony-stimulating factor (CSF) reduced granulocyte/macrophage colony formation in the target layer but did not effect the increased Meg-CSA. While a radioimmunoassay for L-cell type CSF was unable to detect significant differences in concentrated media from control and irradiated cultures, bioassays of these media revealed XRT-related G/M-CSA elevations. These results indicate that the G/M-CSA elaborated in these cultures is immunologically distinct from the Meg-CSA produced, and although distinct from L cell CSF, the G/M-CSA is crossreactive with the L cell CSF antiserum. Morphologic, histochemical, and factor VII antigen immunofluorescent studies were performed on the stromal cell population responsible for production of these stimulatory activities. In addition to ''fat'' cells, the stromal cells remaining after XRT were composed of two predominant cell populations. These included a major population of acid phosphatase and nonspecific esterase-positive macrophage-like cells and a minor population of factor VII antigen negative epithelioid cells

Phyto hormone abscisic acid (ABA) plays a regulatory role in many physiological processes in plants and is regulated and controlled by specific key factors or genes. Different environmental stress conditions such as water, drought, cold, light, and temperature result in increased amounts of ABA. The action of ABA involves modification of gene expression and analysis of in vitro callus model system cultures revealed several potential of constitutive, institutive and up-regulation acting regulatory mechanisms. Therefore, this study was aimed at establishing in vitro cultures as potential research tools to study the regulatory mechanisms of the carotenoid biosynthesis in selected plant species through a controlled environment. The presence and absence of zeaxanthin and neoxanthin in callus cultures and intact plants could be explained by changes in gene expression in response to stress. Abiotic stress can alter gene expression and trigger cellular metabolism in plants. This study suggested that the key factors which involved in regulatory mechanisms of individual carotenoid biosynthesis in a particular biology system of plants can be either be silenced or activated. Therefore, based on the results in this study environmental stress is made possible for enhancement or enrichment of certain carotenoid of interest in food crops without altering the genes. (author)

2016-01-01

Following the Fukushima Daiichi accident in Japan, one of the most important lessons learnt, among other things, was the issue of strengthening the effectiveness of the regulatory bodies. Immediately after the Fukushima accident, National level safety audits were conducted on all operating NPPs in India to review safety of NPPs in India. A national action plan has been prepared to implement the identified short term, midterm and long term measures. The assessment indicates that national response to the Fukushima Accident for safety assessment of NPPs and subsequent actions and initiatives taken for safety enhancement of the NPPs in India are in-line with the objectives of the IAEA Action plan. This paper highlights the actions taken by India in the light of Fukushima Daiichi accident in order to strengthen the regulatory effectiveness through improvements in the existing core processes, challenges faced, Insights gained from the recent initiatives on safety performance indicators and assessment of safety culture, relevant observations of IRRS mission report and Indian perspectives on the further cooperation among the member states for enhancing the regulatory effectiveness for nuclear oversight of regulated organizations.

A Glance on the Safety Culture in Industrial Gamma Radiography in the Philippines: Regulatory Body Perspective

International Nuclear Information System (INIS)

Borras, A.M.

2016-01-01

The current version of the Code of PNRI Regulations (CPR) Part 11 was published in the Official Gazette on 2010. It is just a year ahead of the publication of the IAEA Specific Safety Guide No. 11. In view of these, radiation safety culture in the practice of industrial gamma radiography was not yet fully introduced in the said national regulations in the country. However, it should not be a reflection that the radiation workers in the country specifically in the said field of practice do not exercise positive safety culture. The Nuclear Regulatory Division (NRD)—regulatory arm, although not yet separated from the Philippine Nuclear Research Institute (PNRI0) as mandated by law — the promotional organization, has a well established and systemic regulatory infrastructure. It is attested by several studies and reports, among others. This study aims to assess the status of the existing safety culture in the conduct of industrial gamma radiography in the country through personnel perception survey of the radiation workers, i.e., managers, radiation safety officers, radiographers and radiographer’s assistants, based on the IAEA five characteristics of safety culture stipulated in the IAEA Safety Guide No. GS-G-3.5, “The Management System for Nuclear Installations”. It is assessed by the NRD of the PNRI. Also, the study determines the existence of safety culture as to the perspective of NRD through observations on the conduct of radiographic operations and walk-through of the facility while using the three-level Schein Model, i.e., “artefacts”, “espoused values” and “basic assumptions” and document reviews, among others

Four kinds of McAbs (anti CD 4 , CD 8 , CD 19 and CD 57 ) were used to separate CD 4 , CD 8 , CD 19 (B) and CD 57 (NK) lymphocyte subsets from human peripheral blood by 'Panning-direct' method. First the natural killing activity of each subsets and the regulatory functions between CD 57 and other subsets were studied. Then the effects of low dose radiation on the function of CD 57 cells and the regulatory functions between CD 57 and other subsets were studied. The results showed that the NK activity was found in all of the four subsets, with CD 57 cell having the strongest activity. When CD 4 and CD 57 cells were co-cultured, the total NK activity was higher than that of the sum of these two single subsets, i.e. there was synergistic effect between CD 4 and CD 57 cells. When CD 8 or CD 19 cells were co-cultured separately with CD 57 cells, no synergistic effect was found. Irradiation by gamma rays at doses of 50 cGy and 80 cGy was able to stimulate the function of CD 57 cells. After Cd 4 or CD 57 cells were irradiated, the total NK activity of their co-culture increased significantly. This phenomenon was not found in other subsets. This suggested that low dose radiation can enhance the synergistic action between CD 4 and CD 57 cells. So at least four subsets (CD 4 , CD 8 , CD 19 , CD 57 ) contribute to the total NK activity of peripheral blood mononuclear cells. (15 refs., 4 tabs.)

Environmental regulatory reform in Poland: lessons for industrializing economies

This paper examines the environmental regulatory reform in Poland during the 1990s and uses the findings to consider the extent to which elements of successful regulatory systems are transferable across national boundaries. Drawing on five case studies of privatized firms, a mailed questionnaire, and policy and institutional analysis, it investigates how Poland developed an effective system for managing industrial pollution while also achieving considerable socioeconomic progress. The fundamental legitimacy of the regulators and regulatory process, the availability of information about firms and regulatory intents, and the capacity for case-specific decision-making are among the key explanatory factors. The study also shows how in Poland a good 'fit' between regulatory institutions and policies on one hand and their social context on the other hand has evolved, and how it contributes to the effectiveness of the regulatory system. Industrializing economies can indeed simultaneously pursue environmental protection and socioeconomic welfare, but elements of a proven regulatory system cannot be automatically adopted among countries and cultures. Learning from each other's experience must be sensitive to the cultural and institutional context of each regulatory system. 42 refs., 3 figs., 1 tab.

Regulatory effectiveness is an important attribute of any regulator, particularly nuclear regulators. As the nuclear industry has matured, and as the social landscape has changed, so have views on what constitutes regulatory effectiveness. Canada has evolved its regulatory structure and modernized its legislative framework and technical requirements and guidance over time. In addition, Canada continues to collaborate with international agencies, particularly the NEA and the IAEA, to ensure that there is a common understanding of the indicators and key attributes of regulatory effectiveness. This paper discusses Canadian and international views on the subject, including perspectives from other industries. (author)

Perceptions of regulatory approaches

Halin, Magnus; Leinonen, Ruusaliisa

2012-01-01

Ms. Ruusaliisa Leinonen and Mr. Magnus Halin from Fortum gave a joint presentation on industry perceptions of regulatory oversight of LMfS/SC. It was concluded that an open culture of discussion exists between the regulator (STUK) and the licensee, based on the common goal of nuclear safety. An example was provided of on how regulatory interventions helped foster improvements to individual and collective dose rate trends, which had remained static. Regulatory interventions included discussions on the ALARA concept to reinforce the requirement to continuously strive for improvements in safety performance. Safety culture has also been built into regulatory inspections in recent years. Training days have also been organised by the regulatory body to help develop a shared understanding of safety culture between licensee and regulatory personnel. Fortum has also developed their own training for managers and supervisors. Training and ongoing discussion on LMfS/SC safety culture is considered particularly important because both Fortum and the regulatory body are experiencing an influx of new staff due to the demographic profile of their organisations. It was noted that further work is needed to reach a common understanding of safety culture on a practical level (e.g., for a mechanic setting to work), and in relation to the inspection criteria used by the regulator. The challenges associated with companies with a mix of energy types were also discussed. This can make it more difficult to understand responsibilities and decision making processes, including the role of the parent body organisation. It also makes communication more challenging due to increased complexity and a larger number of stakeholders

Assessing the effectiveness of nuclear regulatory system in India

The Fukushima accident brought up the issue of regulatory effectiveness in the fore. One of the causes of the accident has been attributed to the problems in effectiveness of the Japanese regulatory system. Regulatory reform is underway in Japan and in other countries many efforts have also been made to improve the effectiveness and independence of the regulatory bodies. It is important that the regulatory bodies make self-assessment of their weaknesses and strengths, to achieve the ultimate regulatory goal of assuring acceptable level of nuclear safety. In this paper an assessment has been done for the effectiveness of Indian nuclear regulatory system as implemented by the Atomic Energy Regulatory board (AERB). A number of good practices of AERB have been found and some areas have been identified where improvements are necessary

Embryonic stem cells unlike most adult stem cell populations can replicate indefinitely while preserving genetic, epigenetic, mitochondrial and functional profiles. ESCs are therefore an excellent candidate cell type for providing a bank of cells for allogenic therapy and for introducing targeted genetic modifications for therapeutic intervention. This ability of prolonged self-renewal of stem cells and the unique advantages that this offers for gene therapy, discovery efforts, cell replacement, personalized medicine and other more direct applications requires the resolution of several important manufacturing, gene targeting and regulatory issues. In this review, we assess some of the advance made in developing scalable culture systems, improvement in vector design and gene insertion technology and the changing regulatory landscape.

Material protection, control, and accounting (MPC and A) regulatory documents play an important role in securing and protecting nuclear material by regulating a variety of activities at different hierarchical levels. The development, implementation, and practical application of these regulatory documents requires a significant investment of financial and material resources. Therefore, it is important to evaluate the effectiveness of the regulatory development process and the extent to which regulations improve the effectiveness of MPC and A at nuclear sites. The joint Russian and U.S. Regulatory Development Project has a goal of evaluating the effectiveness of regulatory documents developed for MPC and A. As part of this joint Project, a methodology for evaluating effectiveness has been developed. This methodology was developed around physical protection objectives. The developed methodology specifies physical protection objectives to be accomplished through the implementation of a regulatory system based on the physical protection goals at the nuclear sites. It includes approaches to assessing regulatory effectiveness, the hierarchical structure of physical protection objectives to be accomplished through implementing regulations, a 'mapping' of the physical protection objectives to the regulatory framework, a list of criteria for evaluating the effectiveness of physical protection regulations and effectiveness indicators, as well as means and methods for gathering information and implementation of this evaluation.

Improving nuclear regulation. NEA regulatory guidance booklets volumes 1-14

International Nuclear Information System (INIS)

2011-01-01

A common theme throughout the series of NEA regulatory guidance reports, or 'green booklets', is the premise that the fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear facilities are continuously maintained and operated in an acceptably safe manner. In meeting this objective the regulator must bear in mind that it is the operator that has responsibility for safely operating the nuclear facility; the role of the regulator is to assess and to provide assurance regarding the operator's activities in terms of assuming that responsibility. The full series of these reports was brought together in one edition for the first time in 2009 and was widely found to be a useful resource. This second edition comprises 14 volumes, including the latest on The Nuclear Regulator's Role in Assessing Licensee Oversight of Vendor and Other Contracted Services.

The third International Conference on Effective Nuclear Regulatory Systems (Canada, 2013) identified the main action items that should be addressed, implemented and followed up. The key technical and organizational areas important to strengthening reactor and spent fuel safety have been determined as following: • Regulatory lessons learned and actions taken (since the accident at the Fukushima Daiichi NPP); • Waste management and spent fuel safety; • Emergency management; • Emerging programmes; • Human and organizational factors, safety and security culture. Over time many activities based on results of the IAEA Integrated Regulatory Review Service in the Russian Federation, 2019, and post-mission, 2013, have been implemented. At present there is progress for the national action plan on nuclear safety, preparation and conducting of long term spent fuel management, complementary reviews for nuclear facilities other than Nuclear Power Plants, emergency exercises with the regulatory body participation, improving communication, development of national regulations and improvement of regulatory system in the whole. The regulatory body ensures assistance in development of national regulatory infrastructure, safety culture to the countries planning to construct Russian design facilities (NPPs, RRs). The report outlines the results and future actions to improve nuclear regulation based on systematic approach to safety and particularly reflects the specificity of taking measures for the research reactors.

Nuclear industry with its evolution in 60s came with a number of pros and cons. In order to avoid any accident or incident, highest safety standards and quality control mechanism were established. The relation of regulator with its licensee is critical in the sense of public safety and welfare. The situation when the regulator starts to work for the interests of the industry instead of the public interest and fails to cling with his mission is known as 'regulatory capture' which may cause a number of serious negative effects like radiological or radiation risk. According to George Stigler, as a rule regulation is acquired by the industry and is designed and operated primarily for its benefit. The phenomenon of regulatory capture may hamper the safety culture and can also be considered as regulatory failure. It is therefore necessary to clearly understand this type of government failure to avoid the happening of serious accidents like TMI and Fukushima in the future. This paper aims to explore whether the regulatory body works independently and effectively to achieve its assigned tasks and objectives. Hence we proposed a questionnaire for the self-assessment of regulatory capture within the regulatory body. It also includes the results of an experimental assessment which was carried out to check the relevance and reliability of the questions to this subject. This assessment survey was conducted with the officers and staff members of Pakistan Nuclear Regulatory Authority (PNRA). We checked the significance of the proposed questionnaire and found some of the questions like Q. 27, 30 and 33 (written in italic) are not directly related to the phenomenon of regulatory capture. However, the existence of the situation which has been asked in these questions may lead towards the hampering of regulatory culture.

CD4+CD25+ regulatory T cells (Tregs) are involved in the maintenance of peripheral tolerance and ensure a balanced immune response competent of fighting pathogens and at the same time recognizing commensals as harmless. This feature is lost in Crohn's disease (CD). The forkhead/winged helix transcription factor FoxP3 is a master gene for Treg function and defects in the FoxP3 gene lead to a clinical picture similar to inflammatory bowel disease (IBD). Murine colitis can be cured by adoptive transfer of Tregs and ex vivo-generated gut-specific Tregs represent an attractive option for therapy in CD. Thus, defective Tregs could contribute to the development of CD. We cultured biopsies of colonic mucosa in the presence of high concentrations of interleukin (IL)-2 and IL-4 to overcome the anergic nature of naturally occurring CD4+CD25+ Tregs in the mucosa. We investigated the expression of FoxP3 and regulatory potential of gut-derived CD4+CD25+ T cells cultured from patients with CD and healthy individuals. The FoxP3 expression was analysed by reverse transcriptase polymerase chain reaction (RT-PCR), and the suppressive effect of FoxP3+CD4+CD25+ T cells on proliferation and cytokine production of autologous CD4+ T cells was assessed by flow cytometry. Cultured gut-derived T cells with CD4+CD25+ phenotype expressed FoxP3 and were able as the freshly isolated Tregs from peripheral blood to suppress proliferation and cytokine production of autologous CD4+ T cells. Thus, we demonstrate that FoxP3+CD4+CD25+ T cells with regulatory properties can be propagated in vitro from inflamed mucosa of CD patients, which may be of interest in adoptive immunotherapy.

Human and organizational factors are always of paramount importance at nuclear and radiation safety as well as in the safety regulation provision. Major NPP accidents occurred merely reaffirm this fact. The role of an authority that regulates nuclear safety increases each time in the aftermath of accidents perceived as a shock together with the importance of scientific and technical support. SEC NRS was established in 1987, the next year after the Chernobyl NPP accident aiming to strengthen supervision over works carried out at the nuclear industry enterprises. Currently SEC NRS provides comprehensive scientific and technical support to Rostechnadzor including safety review and regulatory legal documents development to regulate safety along with safety culture.

Cross cultural differences in mood regulation: An empirical comparison of individualistic and collectivistic cultures

2004-01-01

This paper seeks to examine cross cultural differences in the ways people regulate their mood states with special emphasis put on the role of consumption. This issue is virtually unexplored in the extant literature. After briefly introducing the essence of mood regulation and culture we integrate...... these discussions in order to produce six research hypothesis for testing. These hypothesis concern the differences in the nature, perceived ease of initiating, and emotional outcomes of mood regulatory activities. The empirical evidence suggests that mood regulatory activities are less consumption oriented, have...... more socially based emotional consequences, and are more easily pursued and are more effective in collectivistic as opposed to individualistic cultures. The paper concludes by outlining the theoretical and managerial implications of the results and spelling out a few research suggestions....

The achievement of the effectiveness in the performance of a nuclear regulatory body has been a permanent challenge in the recent history of nuclear regulation. In the post-Fukushima era this challenge is even more important. This article addresses the subject from two complementary points of view: the characteristics of an effective regulatory body and the regulatory approaches. This work is based on the most recent studies carried out by the Committee on Nuclear Regulatory Activities, CNRA (OECD/NEA), as well as on the experience of the Consejo de Seguridad Nuclear, CSN, the Spanish regulatory body. Rafael Cid is the representative of CSN in these project: Diego Encinas has participated in the study on regulatory approaches. (Author)

Nowadays some of developing countries in Asian region are announcing their planning to embark the nuclear power program. This progression are rising due to four factor: increasing political instabilities in fossil-fuel exporting countries; declining domestic natural energy resources; growing concerns about greenhouse gas emissions; and increasing demand for electricity. This paper gives a study on the comparison between Canada, Republic of South Korea and Malaysia regarding to their regulatory framework as well as the licensing procedures in controlling the nuclear power plants establishment. Canada and Korea were selected to study because of both of the countries have different system in controlling the nuclear power plants in terms of its regulatory framework as well as the licensing process. The idea is to compare these countries along with the guidelines by the IAEA and to find out what Malaysia could be learn to start the nuclear power program and find out the best practice in nuclear licensing. Factors taken into consideration are the regulatory framework, especially the nature of the licensing authority, the licensing process and enforcement actions. Together, these give a way to evaluate the effectiveness of the regulatory body due to the licensing authorization of nuclear power plant

Why does Safety Culture Matter?

International Nuclear Information System (INIS)

Dahlgren-Persson, Kerstin

2008-01-01

Dr. Kerstin Dahlgren-Persson, from the IAEA presented a plenary paper on 'Why does safety culture matter?'. The paper discussed the main conclusions of a 1998 IAEA conference on shortcomings in safety management. The conference included case studies of TVA, Cooper, Peach Bottom, Millstone, Ontario Hydro, Barsebaeck and Oskarshamn. Common symptoms included insularity; disproportionate focus on technical issues, high initial performance, lack of corporate oversight, changing management direction and cost cutting, repeat problems, and regulatory dissatisfaction. Behind these symptoms was lack of senior utility leadership with the insight, knowledge and ability to manage the unique interaction between the technology, economics, human factors and safety in a changing nuclear environment. Shortcomings relating to the regulator included lack of criteria for when regulatory actions should be taken in response to degradations in safety management, and the inability of some regulators to influence at the senior utility management level. The paper also made the following key points: - Human error is not always symptomatic of a poor safety culture. Effective root cause analysis (such as that carried out for the Columbia accident investigation) is essential to correctly differentiate between situational issues at a point in time and those rooted in organizational culture. - Leaders change culture by holding different assumptions and by making them visible through their words and action. - Regulators should consider how their regulatory strategy influences licensees. For example, a prescriptive strategy can foster a compliance based approach

Natalizumab, a monoclonal humanized antibody targeting the alpha-4 chain of very late activation antigen 4 (VLA-4) exerts impressive therapeutic effects in patients with relapsing-remitting multiple sclerosis. Our objective was to study impacts of Natalizumab therapy on Foxp3+ T regulatory cells (Tregs) in multiple sclerosis (MS) patients. A combined approach of in vitro and ex vivo experiments using T cells isolated from the peripheral blood of healthy donors and Natalizumab treated MS patients was chosen. We determined binding of Natalizumab and its effects on the frequency, transmigratory behaviour and suppressive function of Tregs. Binding of Natalizumab and expression of CD49d (alpha-4 chain of VLA-4) differed between non-regulatory and regulatory cells. Albeit Foxp3+ Tregs had lower levels of CD49d, Natalizumab blocked the transmigration of Foxp3+ Tregs similar to non-regulatory T cells. The frequency of peripheral blood Tregs was unaffected by Natalizumab treatment. Natalizumab does not alter the suppressive capacity of CD4+CD25(high)CD127(low)Foxp3+ Tregs under in vitro conditions. Furthermore, the impaired function of Tregs in MS patients is not restored by Natalizumab treatment. We provide a first detailed analysis of Natalizumab effects on the regulatory T cell population. Our prospective study shows that Foxp3+ Tregs express lower levels of VLA-4 and bind less Natalizumab. We further the understanding of the mechanisms of action of Natalizumab by demonstrating that unlike other immunomodulatory drugs the beneficial therapeutic effects of the monoclonal antibody are largely independent of alterations in Treg frequency or function.

Politically Induced Regulatory Risk and Independent Regulatory Agencies

OpenAIRE

Strausz, Roland

2015-01-01

Uncertainty in election outcomes generates politically induced regulatory risk. Political parties' risk attitudes towards such risk depend on a fluctuation effect that hurts both parties and an output--expansion effect that benefits at least one party. Notwithstanding the parties' risk attitudes, political parties have incentives to negotiate away all regulatory risk by pre-electoral bargaining. Efficient pre-electoral bargaining outcomes fully eliminate politically induced regulatory risk. P...

The role of the regulator in promoting and evaluating safety culture. Operating experience feedback programme approach

International Nuclear Information System (INIS)

Perez, S.

2002-01-01

Promoting and Evaluating Safety Culture (S.C.) in Operating Organizations must be one of the main Nuclear Regulator goals to achieve. This can be possible only if each and every one of the regulatory activities inherently involves S.C. It can be seen throughout attitudes, values, uses and practices in both individuals and the whole regulatory organization. One among all the regulatory tools commonly used by regulators to promote and evaluate the commitment of the licensees with safety culture as a whole involves organizational factors and particular attention is directed to the operating organization. This entailed a wide range of activities, including all those related with management of safety performance. Operating Experience Feedback Programme as a tool to enhance safety operation is particularly useful for regulators in the evaluation of the role of S.C. in operating organization. Safety Culture is recognized as a subset of the wider Organizational Culture. Practices that improve organizational effectiveness can also contribute to enhance safety. An effective event investigation methodology is a specific practice, which contributes to a healthy Safety Culture. (author)

BACKGROUND AIMS. Studies performed using human and animal models have indicated the immunoregulatory capability of mesenchymal stromal cells in several lineages. We investigated whether human dental pulp-derived stem cells (hDP-SC) have regulatory effects on phytohemagglutinin (PHA)-activated CD3(+) T cells. We aimed to define the regulatory mechanisms associated with hDP-SC that occur in mixed lymphocyte reaction (MLR) and transwell systems with PHA-CD3(+) T cells and hDP-SC at a ratio of 1:1. METHODS. Proliferation, apoptosis and pro- and anti-inflammatory cytokines of PHA-CD3(+)T cells, the expression of Regulatory T cells (Treg) markers and some regulatory factors related to hDP-SC, were studied in Both transwell and MLR are co-cultures systems. RESULTS. Anti-proliferative and apoptotic effects of hDP-SC were determined in co-culture systems. Elevated expression levels of human leukocyte antigen (HLA)-G, hepatocyte growth factor (HGF)-β1, intracellular adhesion molecule (ICAM-1)-1, interleukin (IL)-6, IL-10, transforming growth factor (TGF)-β1, vascular adhesion molecule (VCAM)-1 and vascular endothelial growth factor (VEGF) by hDP-SC were detected in the co-culture systems. We observed decreased expression levels of pro-inflammatory cytokines [interferon (IFN)-γ, IL-2, IL-6 receptor (R), IL-12, Interleukin-17A (IL-17A), tumor necrosis factor (TNF)-α] and increased expression levels of anti-inflammatory cytokine [inducible protein (IP)-10] from PHA-CD3(+) T cells in the transwell system. Expression of Treg (CD4(+) CD25(+) Foxp3(+)) markers was significantly induced by hDP-SC in both co-culture systems. We observed apoptosis of PHA-CD3(+) T cells with 24 h using time-lapse camera photographs and active caspase labeling; it is likely that paracrine soluble factors and molecular signals secreted by hDP-SC led this apoptosis. CONCLUSIONS. We suggest that hDP-SC have potent immunoregulatory functions because of their soluble factors and cytokines via paracrine

Alcohol and cannabis: Comparing their adverse health effects and regulatory regimes.

Science.gov (United States)

Hall, Wayne

2017-04-01

The claim that the adverse health effects of cannabis are much less serious than those of alcohol has been central to the case for cannabis legalisation. Regulators in US states that have legalised cannabis have adopted regulatory models based on alcohol. This paper critically examines the claim about adverse health effects and the wisdom of regulating cannabis like alcohol. First, it compares what we know about the adverse health effects of alcohol and cannabis. Second, it discusses the uncertainties about the long term health effects of sustained daily cannabis use. Third, it speculates about how the adverse health effects of cannabis may change after legalisation. Fourth, it questions the assumption that alcohol provides the best regulatory model for a legal cannabis market. Fifth, it outlines the major challenges in regulating cannabis under the liberal alcohol-like regulatory regimes now being introduced. Copyright © 2016 Elsevier B.V. All rights reserved.

Food safety has received a great deal of attention in both developed and developing countries in recent years. In China, the numerous food scandals and scares that have struck over the past decade have spurred signiifcant food safety regulatory reform, which has been increasingly oriented towards the public-private partnership model adopted by the Europe Union’s (EU) food safety regulatory system. This paper analyzes the development of both the EU’s and China’s food safety regu-latory systems, identiifes the current chalenges for China and additionaly considers the role of public-private partnership. The success of co-regulation in the food regulatory system would bring signiifcant beneifts and opportunities for China. Finaly, this paper recommends additional measures like training and grants to improve the private’s sector effectiveness in co-regulating China’s food safety issues.

Principles of resource-effectiveness and regulatory-effectiveness for risk-informed applications: Reducing burdens by improving effectiveness

International Nuclear Information System (INIS)

Vesely, W.E.

1999-01-01

Principles of resource-effectiveness and regulatory-effectiveness are presented which systematically compare the resources expended on a requirement or activity versus its risk importance. To evaluate resource-effectiveness and regulatory-effectiveness, cost-benefit analysis principles are generalized to resource versus risk importance principles. It is shown that by applying resource-importance analyses, current requirements and activities can be systematically evaluated for their resource-effectiveness and their risk-consistency. Strategies can then be developed to maximize both resource-effectiveness and risk-consistency which reduces unnecessary burdens while maintaining risk or reducing risk. The principles, approaches, and implementation schemes which are presented provide a systematic process for evaluating and optimizing resource-effectiveness and regulatory-effectiveness. The illustrations that are presented show that current NRC and industry actions are not resource-effective. By improving their resource-effectiveness and risk-consistency, significant burden reductions are achievable while risk, e.g. core damage frequency, is maintained or is reduced. The illustrations show that by optimizing industry resources and NRC resources with regard to their risk-effectiveness, significant burden reductions are achievable for both the industry and NRC. Algorithms and software exist for broad-scale implementations. Because of the burden reductions which are identified and the improvements in risk-consistency which result, resource-importance analysis should be the first step in risk-informed applications. Resource-importance analysis is so important and can provide such large benefits that it needs to be carried out on all current requirements that are addressed by risk-informed applications

Optimization and radiation protection culture

International Nuclear Information System (INIS)

Jeon, In Young; Shin, Hyeong Ki; Lee, Chan Mi

2013-01-01

Safety culture or radiation protection culture is based in common on the term, 'culture'. Culture is defined as the learned, shared set of symbols and patterns of basic assumptions, which is invented, discovered, or developed by a given group as it learns to cope with its problem of external adaptation and internal integration. Safety culture generally refers to the attitude and behaviors affecting safety performance. The concept of 'Safety Culture' was introduced after the Chernobyl accident in 1986. For the accident, nuclear society reached the conclusion that the cause was the wrong management attitude of the NPP, that is, deficient 'Safety Culture'. Recently, 'Radiation Protection Culture' was introduced as the core concept of nuclear safety culture.

Safety culture or radiation protection culture is based in common on the term, 'culture'. Culture is defined as the learned, shared set of symbols and patterns of basic assumptions, which is invented, discovered, or developed by a given group as it learns to cope with its problem of external adaptation and internal integration. Safety culture generally refers to the attitude and behaviors affecting safety performance. The concept of 'Safety Culture' was introduced after the Chernobyl accident in 1986. For the accident, nuclear society reached the conclusion that the cause was the wrong management attitude of the NPP, that is, deficient 'Safety Culture'. Recently, 'Radiation Protection Culture' was introduced as the core concept of nuclear safety culture. There have been many efforts to establish definition and develop assessment tool for radiation protection culture in international level such as ICRP and IRPA as well as NRC.

Full Text Available Abstract Background Resistin, a member of adipokine family, is known to be involved in the modulation of immune responses including inflammatory activity. Interestingly, resistin is secreted by adipocytes in mice and rats whereas it is secreted by leukocytes in humans. However, the mechanism behind the effect of resistin on the expansion of regulatory T cells (Tregs remains poorly understood. Therefore, we examined regulatory effect of resistin on the induction and cellular modification of Tregs. Results Both protein and mRNA expression of FoxP3, a representative marker of Tregs, increased in a dose-dependent manner when peripheral blood mononuclear cells were treated with resistin. At the same time, resistin had no direct effect on the induction of FoxP3 in CD4+ T cells, suggesting an indirect role through other cells type(s. Since DCs are an important player in the differentiation of T cells, we focused on the role of DCs in the modulation of Tregs by resistin. Resistin suppressed the expression of interferon regulatory factor (IRF-1 and its target cytokines, IL-6, IL-23p19 and IL-12p40, in DCs. Furthermore, FoxP3 expression is increased in CD4+ T cells when co-cultured with DCs and concomitantly treated with resistin. Conclusion Our results suggest that resistin induces expansion of functional Tregs only when co-cultured with DCs.

U.S. Nuclear Regulatory Commission Safety Culture Oversight

International Nuclear Information System (INIS)

Sieracki, D. J.

2016-01-01

The NRC recognises that it is important for all organizations performing or overseeing regulated activities to establish and maintain a positive safety culture commensurate with the safety and security significance of their activities and the nature and complexity of their organizations and functions. The NRC’s approach to safety culture is based on the premise that licencees bear the primary responsibility for safety. The NRC provides oversight of safety culture through expectations detailed in policy statements, safety culture assessor training for NRC inspectors, the oversight process, and the Allegations and Enforcement Programs. The NRC’s Safety Culture Policy Statement (SCPS) sets forth the Commission’s expectation that individuals and organizations establish and maintain a positive safety culture commensurate with the safety and security significance of their activities and the nature and complexity of their organizations and functions. The SCPS is not a regulation. It applies to all licencees, certificate holders, permit holders, authorisation holders, holders of quality assurance program approvals, vendors and suppliers of safety-related components, and applicants for a licence, certificate, permit, authorisation, or quality assurance program approval, subject to NRC authority.

Oversight and Influencing of Licensee Leadership and Management for Safety, Including Safety Culture - Regulatory Approaches and Methods. Proceedings of an NEA/IAEA Workshop, Chester, United Kingdom, 26-28 September 2011

International Nuclear Information System (INIS)

2012-01-01

Both regulators and the nuclear industry recognise the need for licensees to develop a strong, positive safety culture to support successful and sustainable nuclear safety performance. A number of reports have been issued by the IAEA and the NEA on the role of the regulator in relation to oversight of safety culture (References 1 to 5). There has been less clarity on how this should be achieved - in particular, with regard to strategies and practical approaches for maintaining oversight of, and influencing, those facets of licensee leadership and management which have a profound influence on safety culture. In recognition of this, the CSNI Working Group on Human and Organisational Factors (WGHOF), together with the CNRA Working Group on Inspection Practices (WGIP) and the IAEA, organised a workshop in Chester, United Kingdom, in May 2007 to provide a forum for gathering and sharing international experience, including good practices and learning points. The results of the workshop are reported in Reference 6. Workshop participants agreed that, in view of the rapidly developing approaches in this area, it would be sensible to hold a further workshop ('Chester 2') in 3-5 years in order to discuss how regulatory approaches have moved on and to share lessons learned from their application. In 2010, the WGIP hosted a workshop which included regulatory approaches for the assessment of licensee safety culture as a discussion topic. The outputs of the workshop included a list of commendable practices for monitoring and evaluating licensee safety culture (Reference 7). The 'Chester 2' workshop took place in September 2011. This report sets out the findings of the workshop, organised by the UK Office for Nuclear Regulation (ONR) on behalf of the CSNI/WGHOF and the IAEA. The workshop was attended by over 40 representatives of nuclear regulatory bodies and licensees from 15 countries plus IAEA and NEA. The workshop featured keynote papers on learning from major events, and from

The immunoregulatory function of T regulatory cells (Tregs) is impaired in multiple sclerosis (MS). Recent studies have shown that umbilical cord-derived mesenchymal stem cells (UC-MSCs) exert regulatory effect on the functions of immune cells. Thus, we investigated whether UC-MSCs could improve the impaired function of Tregs from MS patients. Co-cultures of UC-MSCs with PBMCs of MS patients were performed for 3 days. Flow cytometry was used to determine the frequency of Tregs. A cell proliferation assay was used to evaluate the suppressive capacity of Tregs. ELISA was conducted for cytokine analysis in the co-cultures. Our results showed that UC-MSCs significantly increased the frequency of CD4+CD25+CD127low/− Tregs in resting CD4+ T cells (pUC-MSC-primed Tregs of MS patients significantly inhibited the proliferation of PHA-stimulated autologous and allogeneic CD4+CD25− T effector cells (Teffs) from MS patients and healthy individuals compared to non-UC-MSC-primed (naïve) Tregs from the same MS patients (pUC-MSC-primed Tregs from MS patients and naïve Tregs from healthy subjects. The impaired suppressive function of Tregs from MS can be completely reversed in a co-culture by UC-MSC modulation. This report is the first to demonstrate that functional defects of Tregs in MS can be repaired in vitro using a simple UC-MSC priming approach. PMID:27705922

The effect of cultural interaction on cumulative cultural evolution.

Science.gov (United States)

Nakahashi, Wataru

2014-07-07

Cultural transmission and cultural evolution are important for animals, especially for humans. I developed a new analytical model of cultural evolution, in which each newborn learns cultural traits from multiple individuals (exemplars) in parental generation, individually explores around learned cultural traits, judges the utility of known cultural traits, and adopts a mature cultural trait. Cultural evolutionary speed increases when individuals explore a wider range of cultural traits, accurately judge the skill level of cultural traits (strong direct bias), do not strongly conform to the population mean, increase the exploration range according to the variety of socially learned cultural traits (condition dependent exploration), and make smaller errors in social learning. Number of exemplars, population size, similarity of cultural traits between exemplars, and one-to-many transmission have little effect on cultural evolutionary speed. I also investigated how cultural interaction between two populations with different mean skill levels affects their cultural evolution. A population sometimes increases in skill level more if it encounters a less skilled population than if it does not encounter anyone. A less skilled population sometimes exceeds a more skilled population in skill level by cultural interaction between both populations. The appropriateness of this analytical method is confirmed by individual-based simulations. Copyright © 2014 Elsevier Ltd. All rights reserved.

POEM: Identifying joint additive effects on regulatory circuits

Directory of Open Access Journals (Sweden)

Maya eBotzman

2016-04-01

Full Text Available Motivation: Expression Quantitative Trait Locus (eQTL mapping tackles the problem of identifying variation in DNA sequence that have an effect on the transcriptional regulatory network. Major computational efforts are aimed at characterizing the joint effects of several eQTLs acting in concert to govern the expression of the same genes. Yet, progress towards a comprehensive prediction of such joint effects is limited. For example, existing eQTL methods commonly discover interacting loci affecting the expression levels of a module of co-regulated genes. Such ‘modularization’ approaches, however, are focused on epistatic relations and thus have limited utility for the case of additive (non-epistatic effects.Results: Here we present POEM (Pairwise effect On Expression Modules, a methodology for identifying pairwise eQTL effects on gene modules. POEM is specifically designed to achieve high performance in the case of additive joint effects. We applied POEM to transcription profiles measured in bone marrow-derived dendritic cells across a population of genotyped mice. Our study reveals widespread additive, trans-acting pairwise effects on gene modules, characterizes their organizational principles, and highlights high-order interconnections between modules within the immune signaling network. These analyses elucidate the central role of additive pairwise effect in regulatory circuits, and provide computational tools for future investigations into the interplay between eQTLs.Availability: The software described in this article is available at csgi.tau.ac.il/POEM/.

Transparency of nuclear regulatory activities

International Nuclear Information System (INIS)

2007-01-01

One of the main missions of nuclear regulators is to protect the public, and this cannot be completely achieved without public confidence. The more a regulatory process is transparent, the more such confidence will grow. Despite important cultural differences across countries, a number of common features characterise media and public expectations regarding any activity with an associated risk. A common understanding of transparency and main stakeholders' expectations in the field of nuclear safety were identified during this workshop, together with a number of conditions and practices aimed at improving the transparency of nuclear regulatory activities. These conditions and practices are described herein, and will be of particular interest to all those working in the nuclear regulatory field. Their implementation may, however, differ from one country to another depending on national context. (authors)

The Role of the Regulator in the Field of Safety Culture to Shun Nuclear Accident

International Nuclear Information System (INIS)

Kandil, M.M.

2016-01-01

The 2011 accident at the Fukushima Daiichi nuclear power plant in Japan has, as might be expected, led to improvements in equipment at plants around the world that have fortified safety systems and allowed for better protection against rare, extreme natural events. Equally important to the process of improving nuclear safety is the emphasis placed on implementing quality improvements to the human side of nuclear safety, a crucial element that is often not considered by those outside the nuclear sector. Ensuring nuclear reactor safety is not only a question of physical protection against all credible threats, enhancing robustness of important safety systems and increasing redundancy of back-up power and water cooling systems, but also one of making certain that qualified and trained staff are supported by effective procedures. However, these assets are valued only in an organizational culture that places a premium on ensuring high levels of safety, or implementing what is called an effective “nuclear safety culture”. Principles, characteristics and factors for effective safety culture are to great extent similar between licencees and regulatory bodies and can be applied for developing RB’s safety. Safety is the primary purpose of the regulatory body, Regulator plays a significant role in the field of nuclear safety even though the prime responsibility for safety belongs to the operator, and it is the regulator which actually decides what is considered to be safe. In order to effectively implement the international principle of high level of nuclear safety, nuclear safety culture should be clearly named as an objective in international nuclear legal acts and the regulator’s responsibility for promotion of nuclear safety culture should be established. What is more difficult for the regulator is finding the right balance of firmness but fairness in dealing with the operator. In addition to enforcing safety regulations, the regulator should have a positive

Nuclear regulatory organisations: Learning from stakeholders to enhance communication

International Nuclear Information System (INIS)

Lorin, Aurelie

2015-01-01

Since its creation 15 years ago, the NEA Committee on Nuclear Regulatory Activities (CNRA) Working Group on Public Communication of Nuclear Regulatory Organisations (WGPC) has been addressing a broad range of communication issues, with two reports recently issued on Nuclear Regulatory Organisations, the Internet and Social Media: The What, How and Why of Their Use as Communication Tools and on Nuclear Regulatory Organisations and Communication Strategies. After the Fukushima Daiichi nuclear power plant accident in 2011, nuclear regulatory organisations around the world reaffirmed the need to strengthen stakeholder outreach and communication, and to create more robust avenues for stakeholder involvement in regulatory matters. The WGPC proposed a means for stakeholders to play a more active role in the group by holding one-day workshops in conjunction with regular meetings. These workshops offer a platform for stakeholder exchange with communication experts from nuclear regulatory organisations (NROs). The objective is to stimulate co-operation and improve communication by better understanding stakeholder perceptions, needs and expectations, and by discussing how to use traditional and social media more effectively. While nuclear regulatory organisations may have a common willingness to improve their communication methods and to build constructive relationships with stakeholders, every country has its own practices and cultural background, and thus its own challenges. Following the first workshop in Paris, which brought together European stakeholders, and the second in North America, the NEA is now organising a third workshop in Asia (Japan) to be held in April 2016. This third workshop will enable the NEA to gather stakeholder views from a third continent. A report on the workshops' findings will be issued after the completion of this third workshop, thus giving a broader idea of how to improve the overall communication methods of nuclear regulatory

Main elements of nuclear regulatory regime in general is presented. These elements are: national rules and safety regulations, system of nuclear facility licensing, activities of regulatory body. Regulatory body is needed to specify the national safety regulations, review and assess the safety documentation presented to support license application, make inspections to verify fulfilment of safety regulations and license conditions, monitor the quality of work processes of user organization, and to assess whether these processes provide a high safety level, promote high safety culture, promote maintenance and development of national infrastructure relevant to nuclear safety, etc

On "feeling right" in cultural contexts: how person-culture match affects self-esteem and subjective well-being.

Whether one is in one's native culture or abroad, one's personality can differ markedly from the personalities of the majority, thus failing to match the "cultural norm." Our studies examined how the interaction of individual- and cultural-level personality affects people's self-esteem and well-being. We propose a person-culture match hypothesis that predicts that when a person's personality matches the prevalent personalities of other people in a culture, culture functions as an important amplifier of the positive effect of personality on self-esteem and subjective well-being at the individual level. Across two studies, using data from more than 7,000 individuals from 28 societies, multilevel random-coefficient analyses showed that when a relation between a given personality trait and well-being or self-esteem exists at the individual level, the relation is stronger in cultures characterized by high levels of that personality dimension. Results were replicated across extraversion, promotion focus, and locomotive regulatory mode. Our research has practical implications for the well-being of both cultural natives and migrants.

Role of the Regulatory Body in Implementing Defence in Depth in Nuclear Installations - Regulatory Oversight in Egypt

Energy Technology Data Exchange (ETDEWEB)

El-Sheikh, B. M., E-mail: badawymel@yahoo.com [Egyptian Nuclear and Radiological Regulatory Authority Cairo (Egypt)

2014-10-15

The fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear facilities are operated at all times in an acceptably safe manner including the safe conduct of decommissioning activities. Defence in depth is recognized as one of the fundamental safety principles that underlie the safety of nuclear power plants. Defence in depth is implemented to provide a graded protection against a wide variety of transients, incidents and accidents, including equipment failures and human errors within nuclear power plants and events initiated outside plants. The Regulator Body plays an important role in implementing defence in depth in nuclear installations in the context of a clear allocation of responsibilities with an operating organization. This role starting with setting safety objectives and by its own independent review and technical assessment of the safety justifications provided by the operating organization in addition to safety culture investigating within relevant organizations. This paper briefly reviews this role in normal operation and post accidents, and its effects on overall nuclear safety in nuclear installations with reference to Egyptian regulatory oversight.

The establishment of the safety culture

International Nuclear Information System (INIS)

Touzet, R.E.

1998-01-01

The first step in the establishment of the Safety Culture is splitting this concept into the elements involved in the same, so as to facilitate and approach to the issue. Then, two methodologies must be introduced, which shall perform independently, although synergically: (1) an 'updated' Quality Assurance Program and (2) a Program of Non-Technical (psychological and social) Activities aimed at stimulating motivation among the individuals in the Organization and at facilitating team work. Later on, once the necessary experience has been gained, the management of the organization must be based, essentially, on continuous development and on making full use of the skills of the individuals involved. In order to be successful, the establishment of a new culture of business management requires three key elements: 1) a working method containing the adequate indicators for measuring progress; 2) the commitment of the managers and the participation of all the staff; 3) the attainment of a net economical benefit that is made evident through an increase in productivity. However, all these actions refer only to one of the components of the system: the Operator of a Nuclear Power Plant, while Safety Culture must involve the whole National System, including the Government and the Regulatory Authority. The introduction of a new culture must necessarily bring along the acceptance of new concepts, new criteria and new methodologies among all the decision makers in the National System. Therefore, a change in culture must include a change in the culture of the Regulatory Authority. For instance, an evaluation of the Safety Culture is not workable by means of a conventional audit or a regulatory inspection. The fact is that what is easy to measure is not the main thing and what is difficult to measure is the only thing that actually matters. Summarizing: 'The Regulatory Authority shall be unable to verify the results because the evidences are intangible', but it shall indeed be able

Approach to the safety culture in the Slovak Republic

International Nuclear Information System (INIS)

Kuchta, L.; Sladek, V.

2002-01-01

The Nuclear Regulatory Authority of the Slovak Republic was established on January 1st, 1993, after division of former Czech and Slovak Federation Republic to two independent states - Czech Republic and Slovak Republic. As there were inherited four units on the site Jaslovske Bohunice and Interim Spent Fuel Storage on the same site under operation and four units under construction on site Mochovce it was necessary to keep on regulatory activities from very beginning of regulatory authority existence. The new regulator has been all time co-operating closely with IAEA and countries with developed nuclear power to cover all nuclear safety related areas including the safety culture. It is, however, to be said, that the issue of safety culture begun to be an object of considerations of Czechoslovak NPPs as early as in 1986 after issue of IAEA INSAG 1. Since that time the NPPs try to enforce the safety culture principles as a part of nuclear safety into their daily work in consensus with an utility Slovenske elektrarne, nuclear power plants and Nuclear Regulatory Authority. A purpose of the article is to provide an overview on safety culture practices at nuclear installations in the Slovak Republic. (author)

Enhancing regulatory effectiveness by improving the process for identifying and resolving generic issues

International Nuclear Information System (INIS)

Vander Molen, Harold J.

2001-01-01

The Generic Issues Program first began formally in response to a Commission directive in October of 1976. In 1983, it became one of the first programs to make successful use of probabilistic risk information to aid in regulatory decision-making. In the 16 years since the program became quantitative, 836 issues have been processed. Of these, 106 reactor safety issues were prioritized as requiring further evaluation to determine the final resolution. Approximately a dozen generic issues remain unresolved. Although there is far less reactor licensing activity than in the 1970s, new issues continue to be identified from research and operational experience. These issues often involve complex and controversial questions of safety and regulation, and an efficient and effective means of addressing these issues is essential for regulatory effectiveness. Issues that involve a significant safety question require swift, effective, enforceable, and cost-effective regulatory actions. Issues that are of little safety significance must be quickly shown to be so and dismissed in an expeditious manner so as to avoid unnecessary expenditure of limited resources and to reduce regulatory uncertainty. Additionally, in the time since the generic issue program began, probabilistic risk assessment techniques have advanced significantly while agency resources have continued to diminish. Accordingly, the paper discusses the steps that have been taken to enhance the effectiveness and efficiency of the generic issue resolution process. Additionally, four resolved issues are discussed, along with key elements of a proposed new procedure for resolving potential generic issues

Causality analysis detects the regulatory role of maternal effect genes in the early Drosophila embryo

Directory of Open Access Journals (Sweden)

Zara Ghodsi

2017-03-01

Full Text Available In developmental studies, inferring regulatory interactions of segmentation genetic network play a vital role in unveiling the mechanism of pattern formation. As such, there exists an opportune demand for theoretical developments and new mathematical models which can result in a more accurate illustration of this genetic network. Accordingly, this paper seeks to extract the meaningful regulatory role of the maternal effect genes using a variety of causality detection techniques and to explore whether these methods can suggest a new analytical view to the gene regulatory networks. We evaluate the use of three different powerful and widely-used models representing time and frequency domain Granger causality and convergent cross mapping technique with the results being thoroughly evaluated for statistical significance. Our findings show that the regulatory role of maternal effect genes is detectable in different time classes and thereby the method is applicable to infer the possible regulatory interactions present among the other genes of this network.

Regulatory difficulties in a developing country

International Nuclear Information System (INIS)

Jacobs, W.R. Jr.

1978-01-01

The regulatory agency assigned the task of regulating the initial entry into the field of nuclear power generation by a developing country has a very difficult job. Based on the authors' experience during the start-up and initial operation of Ko-Ri Unit I, the first power reactor in the Republic of Korea, observations on regulatory difficulties and recommendations for improved regulatory effectiveness are offered. The problem areas can be loosely grouped into three general categories: (1) Lack of adequate technical knowledge which is the basis for all effective regulation; (2) Difficulties with understanding and utilization of the required regulatory documentation; (3) Failure to establish the proper regulatory environment. Examples are cited from actual experience during the Ko-Ri Unit I start-up to demonstrate the impact that regulatory activities can have on a plant construction and testing programme. The problems encountered are not unique to developing countries but also exist in the United States of America. Recommendations are offered which should be beneficial to either newly formed regulatory agencies or agencies wishing to improve their abilities and effectiveness. These include: (1) Additional training of regulatory inspectors in plant operations; (2) Additional experience gained by participation in regulatory activities in other countries; (3) Increased attention given to regulatory documents, especially plant technical specifications; (4) Establishment of formal lines of communication between the utility and the regulatory agency; (5) Clear definition of regulatory responsibilities to avoid areas of overlapping jurisdiction; (6) Active participation by the regulatory staff very early in the project. It is hoped that these and other recommendations offered will greatly improve regulatory effectiveness and at the same time demonstrate that when the decision is made to 'go nuclear', a strong commitment must be made to develop and support a technically

Public education through safety culture demonstration

International Nuclear Information System (INIS)

Wanitsuksombut, Warapon

2005-01-01

The activities relating to nuclear energy have been world widely opposed against, because there have existed scars in the past; atomic bombs and a few accidents in nuclear facilities. It cannot be denied that the most effective education of public is through Medias such as news or documentary on newspaper and television. Once such cases appeared to public, it is difficult to erase the bad pictures from their memory. Since education for public is mainly depending on media, it is recommended putting harder effort on dissemination of information on regulation and regulatory function to public. The regulatory function of each country is the key of safe utilization of nuclear energy. Since prime responsibility of maintenance and operation are rested on the operators. To achieve the goal of safety, regulatory authority's task now is emphasized on encouraging operators of nuclear facilities to implement their safety culture. This will reduce the probability of unwanted events and therefore raising credit of nuclear energy. (author)

Regulatory focus and burnout in nurses: The mediating effect of perception of transformational leadership.

Shi, Rui; Zhang, Shilei; Xu, Hang; Liu, Xufeng; Miao, Danmin

2015-12-01

This correlation study investigated the relationship between nurses' regulatory focus and burnout, as mediated by their perceptions of transformational leadership, using a cross-sectional research design with anonymous questionnaires. In July-August 2012, data were collected from 378 nurses from three hospitals in Shaanxi Province, China, using self-report questionnaires for measuring the nurses' regulatory focus, their level of burnout and their perception of whether the leadership of their supervisor was transformational. Structural equation modelling and bootstrapping procedures were used to identify the mediating effect of their perceptions of transformational leadership. The results supported our hypothesized model. The type of regulatory focus emerged as a significant predictor of burnout. Having a perception of transformational leadership partially mediated the relationship between regulatory focus and burnout. Having a promotion focus reduced burnout when the participants perceived transformational leadership, whereas having a prevention focus exhibited the opposite pattern. The mediating effect of the perception of transformational leadership suggests that a promotion focus may help diminish burnout, directly and indirectly. Nurse managers must be aware of the role of a regulatory focus and cultivate promotion focus in their followers. © 2014 Wiley Publishing Asia Pty Ltd.

Safety culture in industrial radiography facility

International Nuclear Information System (INIS)

Vincent-Furo, Evelyn

2015-02-01

This project reviewed published IAEA materials and other documents on safety culture with specific references to industrial radiography. Safety culture requires all duties important to safety to be carried out correctly, with alertness, due thought and full knowledge, sound judgment and a proper sense of accountability. The development and maintenance of safety culture in an operating organization has to cover management systems, policies, responsibilities, procedures and organizational arrangements. The essence is to control radiation hazard, optimize radiation protection to prevent or reduce exposures and mitigate the consequences of accidents and incidents. To achieve a high degree of safety culture appropriate national and international infrastructure should exist to ensure effective training of workers and management system that supports commitment to safety culture at all level of the organization; management, managers and workforce. The result of the review revealed that all accidents in industrial radiography facilities were due to poor safety culture practices including inadequate regulatory control oversight. Some recommendations are provided and if implemented could improve safety culture leading to good safety performance which will significantly reduce accidents and their consequences in industrial radiography. These examples call for a review of safety culture in Industrial radiography. (au)

The impact of the social environment on healthy eating awareness results from complex interactions among physical, economic, cultural, interpersonal and individual characteristics. This study investigated the impact of social support and social influence on healthy eating awareness, controlling for socio-economic status, gender and age. Additionally, the mediating effect of self-regulation strategies was examined. A total of 2764 children and adolescents aged 10-17 from four European countries completed self-report measures on healthy eating awareness, social influence and the use of self-regulation strategies. Healthy eating awareness and the use of self-regulation strategies were more likely to occur among younger participants. An interaction between gender and age was related to the use of some self-regulation strategies; compared to girls, boys decreased the use of self-regulation strategies more from pre-adolescence to adolescence. Peer social influence was associated with more unhealthy eating in older participants. Results suggest a need to promote self-regulatory competences among young people in order to assist them with regulating their eating behaviours, especially in the presence of peers. Both school-based interventions and family-based interventions, focusing on self-regulation cognitions and social (peer) influence, could help children and adolescents to use self-regulatory strategies which are essential to eat healthier.

Full Text Available atar has a rich national and cultural identity. Particular customs and traditions characterize the Qatari cultural heritage. Globalization, though, has generated a lot of controversy with regard to the rise of a global culture. Western norms and practices are gradually being transported across the globe and becoming the accepted way of behaviour. The purpose of this article is to examine the effect of globalization on Qatari culture. The sample in this study consisted of (36 participants of Qatari nationality. Employing the focus group interview technique, a semi-structured questionnaire was used as a research method. Participants confirmed that globalization has had a significant effect on the country’s culture. From the participants’ viewpoints, globalization had a negative impact on religion, family connections, customs, manners and language. One the other hand, there has been a positive impact on the educational system and women’s rights.

Regulatory agencies and regulatory risk

OpenAIRE

Knieps, Günter; Weiß, Hans-Jörg

2008-01-01

The aim of this paper is to show that regulatory risk is due to the discretionary behaviour of regulatory agencies, caused by a too extensive regulatory mandate provided by the legislator. The normative point of reference and a behavioural model of regulatory agencies based on the positive theory of regulation are presented. Regulatory risk with regard to the future behaviour of regulatory agencies is modelled as the consequence of the ex ante uncertainty about the relative influence of inter...

Guidelines for IAEA International Regulatory Review Teams (IRRTs)

International Nuclear Information System (INIS)

2002-01-01

The IAEA International Regulatory Review Team (IRRT) programme provides advice and assistance to Member States to strengthen and enhance the effectiveness of the nuclear regulatory body whilst recognizing the ultimate responsibility of each Member State for nuclear safety. The IRRT programme, initiated in 1989, is not restricted to any particular group of Member States, whether developing or industrialized, but is available to all countries with nuclear installations in operation or approaching operation. The basic concepts, purposes and functions of a national regulatory body are well recognized in all Member States having a nuclear power programme. The IAEA Safety Standards Series publication entitled 'Legal and Governmental Infrastructure for Nuclear, Radiation, Radioactive Waste and Transport Safety, Safety: Requirements', No. GS-R-1 (2000), provides a general consensus reference for the practices necessary for a national organization to fulfil the regulatory purposes and discharge the regulatory functions. The Requirements also defines the terms used in these guidelines. The guidance given in the Requirements recognizes that the organizational structure and regulatory processes will vary from country to country depending on their existing constitutional, legal and administrative systems; the size and structure of their nuclear programme; the technical skills and professional and financial resources available to their regulatory body, and social customs and cultural traditions. The objective of this report is to provide guidance on the basic structure of an IRRT mission and provide a common reference both across the various areas covered by an IRRT mission and across all the missions in the programme. As such, it is addressed, principally, to the team members of IRRT missions but it also provides guidance to a host regulatory body receiving a mission. This report identifies the objectives of the IRRT mission and sets out the scope of the topic areas that are

In his opening remarks, Mr. Liu Hua, the President of the conference, noted that the presence of so many attendees at the conference indicated a high level of interest in effective nuclear regulation. He added that effective regulatory systems are very important in maintaining and improving global nuclear safety, and that the first conference on this topic, held ten years ago, created a valuable platform for achieving that goal. In the intervening decade, through the conferences held in Moscow, Cape Town, Ottawa and Vienna, the importance of effective regulation has become more widely recognized and key elements, including independence, transparency, openness, competence and wider international cooperation, have been identified. Mr. Liu Hua pointed to specific actions proposed for governments, regulatory bodies and stakeholders, and highlighted that many of the actions had already achieved fruitful outcomes. He also noted that many lessons had been learned and many improvements had been made in the light of the Fukushima Daiichi accident: 1. To further improve government infrastructure; 2. To further improve nuclear safety standards; 3. To further develop regulation capacity building and human resource; 4. To further enhance knowledge and experience management and transition, 5. To further foster and strengthen nuclear safety culture; 6. To further improve and rebuild public confidence

Full text: The Nuclear Regulatory Authority of Argentina (ARN) is empowered to regulate and control the nuclear activity with regard to radiation and nuclear safety, physical protection and nuclear non-proliferation issues. It must also advise the Executive on issues under its purview. The objective of the Nuclear Regulatory Authority is to establish, develop and enforce a regulatory system applicable to all nuclear activities carried out in Argentina. Two of the goals of this regulatory system are to provide an appropriate standard of protection for individuals against the harmful effects of ionizing radiation, and to maintain a reasonable degree of radiological and nuclear safety in the nuclear activities performed in Argentina. The responsibility of the radiation protection community in performing the tasks to accomplish this goals is twofold. On one hand, it must ensure a high technical quality in performing these functions. It must also provide information on its activities which has to be accurate, comprehensive and understandable. The way a society understands the concept of 'risk' needs to be kept in mind. Risk perception is the subjective judgment that people make about the characteristics and severity of a risk. Cultural theory refers to theories of risk perception that focus on culture, rather than individual psychology as an explanation for differences in risk judgments. It is widely agreed that trust is a key factor in influencing people's perceptions of risk. It is understood there are two main ways trust may impact in risk perceptions: an activity is perceived as more risky if the people or agencies managing it are perceived as untrustworthy; and information presented by trusted sources is given more credibility than information from untrusted sources. One of the primary purposes of ARN's Communication Program is to provide a means whereby those engaged in radiation protection activities may communicate more readily with each other and the public and

The objective of this study is to assess the SC of the Pakistan Nuclear Regulatory Authority (PNRA) by developing a performance indicator-based questionnaire. Aspects that potentially play important roles in developing perceptions of SC, including age, type of job, gender and duty hours of regulatory staff, are given due importance in this study. The study also identifies the strengths and weaknesses in the SC of the PNRA and can be used as a model study to assess the SC of other RBs. The questionnaire, developed to assess the SC of the PNRA, was in line with the PNRA's own defined attributes for SC. In the past, significant efforts have been made to ensure the safe operation of NPPs by improving designs and operating procedures; however, the nuclear accident at the Fukushima NPP in Japan in March 2011 revealed that the currently allotted hardware safety margins are not sufficient, and much work is needed to improve safety management in terms of SC. Initially, the concept of SC was introduced for operating organizations to ensure safe operation of NPPs; nonetheless, more recent investigations of nuclear events and accidents, especially Fukushima, and at Davis-Besse, in the US, have revealed that a strong focus is required to address and improve the SC of Regulatory Bodies (RBs). Strong SC is considered a vital tool for RBs to achieve their objectives and discharge their responsibilities in an effective and efficient manner. Though the relationship between the SC of RBs and that of operating organizations is not straight forward, it is believed that the former has a strong influence over the latter. The questionnaire was consistent in terms of the credible nature of its questions, and the response group covered different levels of PNRA staff, from managers to lower level staff. The results show that the PNRA staff have a very good understanding of the nature and significance of attributes of SC and are doing their best to exercise the same within the

The Political Economy of Regulatory Risk

OpenAIRE

Strausz, Roland

2009-01-01

I investigate the argument that, in a two–party system with different regulatory objectives, political uncertainty generates regulatory risk. I show that this risk has a fluctuation effect that hurts both parties and an output–expansion effect that benefits one party. Consequently, at least one party dislikes regulatory risk. Moreover, both political parties gain from eliminating regulatory risk when political divergence is small or the winning probability of the regulatory–risk–averse party ...

The effect of culture on perspective taking.

Science.gov (United States)

Wu, Shali; Keysar, Boaz

2007-07-01

People consider the mental states of other people to understand their actions. We evaluated whether such perspective taking is culture dependent. People in collectivistic cultures (e.g., China) are said to have interdependent selves, whereas people in individualistic cultures (e.g., the United States) are said to have independent selves. To evaluate the effect of culture, we asked Chinese and American pairs to play a communication game that required perspective taking. Eye-gaze measures demonstrated that the Chinese participants were more tuned into their partner's perspective than were the American participants. Moreover, Americans often completely failed to take the perspective of their partner, whereas Chinese almost never did. We conclude that cultural patterns of interdependence focus attention on the other, causing Chinese to be better perspective takers than Americans. Although members of both cultures are able to distinguish between their perspective and another person's perspective, cultural patterns afford Chinese the effective use of this ability to interpret other people's actions.

Regulatory control of nuclear power plants

International Nuclear Information System (INIS)

2002-01-01

The purpose of this book is to support IAEA training courses and workshops in the field of regulatory control of nuclear power plants as well as to support the regulatory bodies of Member States in their own training activities. The target group is the professional staff members of nuclear safety regulatory bodies supervising nuclear power plants and having duties and responsibilities in the following regulatory fields: regulatory framework; regulatory organization; regulatory guidance; licensing and licensing documents; assessment of safety; and regulatory inspection and enforcement. Important topics such as regulatory competence and quality of regulatory work as well as emergency preparedness and public communication are also covered. The book also presents the key issues of nuclear safety such as 'defence-in-depth' and safety culture and explains how these should be taken into account in regulatory work, e.g. during safety assessment and regulatory inspection. The book also reflects how nuclear safety has been developed during the years on the basis of operating experience feedback and results of safety research by giving topical examples. The examples cover development of operating procedures and accident management to cope with complicated incidents and severe accidents to stress the importance of regulatory role in nuclear safety research. The main target group is new staff members of regulatory bodies, but the book also offers good examples for more experienced inspectors to be used as comparison and discussion basis in internal workshops organized by the regulatory bodies for refreshing and continuing training. The book was originally compiled on the basis of presentations provided during the two regulatory control training courses in 1997 and 1998. The textbook was reviewed at the beginning of the years 2000 and 2002 by IAEA staff members and consistency with the latest revisions of safety standards have been ensured. The textbook was completed in the

Effects of oxygen limitation on sugar metabolism in yeasts: a continuous-culture study of the Kluyver effect.

Science.gov (United States)

Weusthuis, R A; Visser, W; Pronk, J T; Scheffers, W A; van Dijken, J P

1994-04-01

Growth and metabolite formation were studied in oxygen-limited chemostat cultures of Saccharomyces cerevisiae CBS 8066 and Candida utilis CBS 621 growing on glucose or maltose at a dilution rate of 0.1 h-1. With either glucose or maltose S. cerevisiae could be grown under dual limitation of oxygen and sugar. Respiration and alcoholic fermentation occurred simultaneously and the catabolite fluxes through these processes were dependent on the magnitude of the oxygen feed. C. utilis could also be grown under dual limitation of glucose and oxygen. However, at very low oxygen feed rates (i.e. below 4 mmol l-1 h-1) growth was limited by oxygen only, as indicated by the high residual glucose concentration in the culture. In contrast to S. cerevisiae, C. utilis could not be grown anaerobically at a dilution rate of 0.1 h-1. With C. utilis absence of oxygen resulted in wash-out, despite the presence of ergosterol and Tween-80 in the growth medium. The behaviour of C. utilis with respect to maltose utilization in oxygen-limited cultures was remarkable: alcoholic fermentation did not occur and the amount of maltose metabolized was dependent on the oxygen supply. Oxygen-limited cultures of C. utilis growing on maltose always contained high residual sugar concentrations. These observations throw new light on the so-called Kluyver effect. Apparently, maltose is a non-fermentable sugar for C. utilis CBS 621, despite the fact that it can serve as a substrate for growth of this facultatively fermentative yeast. This is not due to the absence of key enzymes of alcoholic fermentation. Pyruvate decarboxylase and alcohol dehydrogenase were present at high levels in maltose-utilizing cells of C. utilis grown under oxygen limitation. It is concluded that the Kluyver effect, in C. utilis growing on maltose, results from a regulatory mechanism that prevents the sugar from being fermented. Oxygen is not a key factor in this phenomenon since under oxygen limitation alcoholic fermentation of

Sugar in disguise or healthy indulgence: A cross-cultural comparision of the perceptions of dietary vice/virtue bundles

Directory of Open Access Journals (Sweden)

Jiraporn Napatsorn

2016-07-01

Full Text Available Consumers often choose virtue food to attain health goals and vice food to achieve indulgence goals. However, food and beverage companies have begun to nullify the vice and virtue categories by bundling vice and virtue ingredients into a single item (e.g. Yogurt with Oreo topping. This research contrasts how consumers from Asian and Western cultures evaluate such vice/virtue food bundles. Building on the perceptual processes and regulatory focus literatures, two cross-cultural experiments using participants in Thailand and the U.S. shows that Westerners prefer virtue-heavy bundles to vice-heavy bundles while Asians show similar preference across both types of bundle. Process measures revealed that Asians perceive greater fit between vice and virtue components in the bundles than Westerners and this perceived fit mediates the effect of culture on their food choice. Study 2 reveals the boundary condition. Specifically, when regulatory focus was manipulated, the effect of culture is no longer significant. The findings provide managerial implications for food and beverage companies as well as contributions to consumer behavior literature.

FORECAST: Regulatory effects cost analysis software annual

International Nuclear Information System (INIS)

Lopez, B.; Sciacca, F.W.

1991-11-01

Over the past several years the NRC has developed a generic cost methodology for the quantification of cost/economic impacts associated with a wide range of new or revised regulatory requirements. This methodology has been developed to aid the NRC in preparing Regulatory Impact Analyses (RIAs). These generic costing methods can be useful in quantifying impacts both to industry and to the NRC. The FORECAST program was developed to facilitate the use of the generic costing methodology. This PC program integrates the major cost considerations that may be required because of a regulatory change. FORECAST automates much of the calculations typically needed in an RIA and thus reduces the time and labor required to perform these analysis. More importantly, its integrated and consistent treatment of the different cost elements should help assure comprehensiveness, uniformity, and accuracy in the preparation of needed cost estimates

Assessment of factors that affect the effectiveness of regulatory bodies: an application to the nuclear area

International Nuclear Information System (INIS)

Almeida, Ivan Pedro Salati de

2005-09-01

This work examines the main factors that affect the effectiveness of the non-economic regulatory process and establishes a model to propose actions to improve the regulation and the role of the regulatory body. The Soft Systems Methodology (SSM) is used and some tools for analysis, derived from the expectations of the stake holders, are added to the methodology. The stake holders taken into account are the public, the licensees, the supervisory bodies, other regulatory bodies, international organizations, concerned groups, and the regulatory body staff. The proposed actions aim to gradually change the organization, and the adopted methodology sees the organizational evolution as a continuum. Some elements of the Theory of Complexity are compared to the SSM concepts in order to validate the evolutionary approach. The model is applied to the specific case of,the nuclear regulation and the Brazilian regulatory body. Situations perceived as 'problem situations' are listed and some actions are proposed for improvement, including the establishment of performance indicators for effectiveness in nuclear regulation.

Jung, Su Jin; Choi, Young Sung; Oh, Jang Jin

2015-01-01

In Korea, the safety policy statement declared in 1994 by government stressed the importance of safety culture and licensees were encouraged to manage and conduct their self-assessments. A change in regulatory position about safety culture oversight was made after the event of SBO cover-up in Kori unit 1 and several subsequent falsification events. Since then KINS has been developing licensee's safety culture oversight system including conceptual framework of oversight, prime focus area for oversight, and specific details on regulatory expectations, all of which are based on defence-in-depth (DiD) safety enhancement approach. Development and gathering of performance data which is related to actual 'safety' of nuclear power plant are needed to identify the relationship between safety culture and safety performance. Authors consider this study as pilot which has a contribution on verifying the construct validity of the model and the effectiveness of survey based research. This is the first attempt that the validity of safety culture oversight model has been investigated with empirical data obtained from Korean nuclear power operating organization

The paper is intended to make an approach for assessing the effectiveness of regulatory activities in Peru by using of performance indicators for each of the activities developed pursuant their responsibilities. So inspections, authorizations, enforcement and regulation activities are qualified by levels of attainments and then assessed independently to rise specific issues. The general conclusion is that regulatory activities seems to be acceptable but some improvements are needed in order to reach a good level of performance. (author)

European Union International Cooperation to Improve Regulatory Effectiveness in Nuclear Safety

International Nuclear Information System (INIS)

Stockmann, Y.

2016-01-01

The European Union (EU) promotes a high level of nuclear safety worldwide, through the ''Instrument for Nuclear Safety Cooperation'' (INSC) since 2007. The INSC builds on the experience gained under the completed ''Technical Assistance to the Commonwealth of Independent States'' Programme (TACIS) from 1991. Development and strengthening of national Regulatory Authorities’ capabilities is a key activity in achieving the INSC goals, in particular in countries with or embarking on nuclear power. Specific partner countries under INSC include countries of all types of maturity in the nuclear technology, with mature countries such as Brazil, Mexico and Ukraine, countries with waste and mining issues, but no direct intention of embarking on nuclear power such as Georgia, Mongolia, Tajikistan, Kyrgyzstan and Tanzania and countries planning to embark on nuclear power such as Belarus, Egypt, Jordan and Vietnam. For new projects, the main focus is on the neighbourhood of the EU. The EU cooperation within INSC encompasses measures to support the promotion of high standards in radiation protection, radioactive waste management, decommissioning, remediation of contaminated sites, and efficient and effective safeguards of nuclear material. The INSC regulatory support is aimed at continuous assistance to Nuclear Regulatory Authorities (NRAs), including their technical support organisations (TSOs), in order to reinforce the regulatory framework, notably concerning licensing activities.

Developing self-regulation for dietary temptations: intervention effects on physical, self-regulatory and psychological outcomes.

McKee, Heather C; Ntoumanis, Nikos

2014-12-01

We aimed to investigate whether a self-regulatory skills intervention can improve weight loss-related outcomes. Fifty-five participants (M BMI = 32.60 ± 4.86) were randomized into self-regulation training and advice groups and received two training workshops and weekly practice tasks. The self-regulation training group was trained to use six self-regulatory skills: Delayed gratification, thought control, goal setting, self-monitoring, mindfulness, and coping. The advice group received dietary and physical activity advice for weight loss. Physical, self-regulatory, and psychological measures were taken at baseline, end of intervention (week 8) and at follow-up (week 12). Using intention-to-treat analysis, weight, waist circumference, body fat and body mass index (BMI) were significantly reduced at follow-up for both groups. There were significant increases in all six self-regulatory skills and the psychological measures of self-efficacy, self-regulatory success, and physical self-worth for both groups. Results indicate that self-regulatory skills training might be as effective as dietary and physical activity advice in terms of weight loss and related outcomes.

To enable the regulatory review to be effectively undertaken by the regulatory body, there is a need for it to have ready access to information generated by research activities. Certain advantages have been seen to be gained by the regulatory body itself directly allocating and controlling some portion of these activities. The princial reasons for reaching this conclusion are summarised and a brief description of the Inspectorates directly sponsored programme outlined. (author)

Effectively identifying regulatory hotspots while capturing expression heterogeneity in gene expression studies

Science.gov (United States)

2014-01-01

Expression quantitative trait loci (eQTL) mapping is a tool that can systematically identify genetic variation affecting gene expression. eQTL mapping studies have shown that certain genomic locations, referred to as regulatory hotspots, may affect the expression levels of many genes. Recently, studies have shown that various confounding factors may induce spurious regulatory hotspots. Here, we introduce a novel statistical method that effectively eliminates spurious hotspots while retaining genuine hotspots. Applied to simulated and real datasets, we validate that our method achieves greater sensitivity while retaining low false discovery rates compared to previous methods. PMID:24708878

Team structure and regulatory focus: the impact of regulatory fit on team dynamic.

Science.gov (United States)

Dimotakis, Nikolaos; Davison, Robert B; Hollenbeck, John R

2012-03-01

We report a within-teams experiment testing the effects of fit between team structure and regulatory task demands on task performance and satisfaction through average team member positive affect and helping behaviors. We used a completely crossed repeated-observations design in which 21 teams enacted 2 tasks with different regulatory focus characteristics (prevention and promotion) in 2 organizational structures (functional and divisional), resulting in 84 observations. Results suggested that salient regulatory demands inherent in the task interacted with structure to determine objective and subjective team-level outcomes, such that functional structures were best suited to (i.e., had best fit with) tasks with a prevention regulatory focus and divisional structures were best suited to tasks with a promotion regulatory focus. This contingency finding integrates regulatory focus and structural contingency theories, and extends them to the team level with implications for models of performance, satisfaction, and team dynamics.

Development of measures to assess the safety of existing NPPs and the effectiveness of regulations and regulatory actions (including 'prescriptive' and 'performance based' approaches). Peer discussions on regulatory practices

International Nuclear Information System (INIS)

1996-09-01

This report arises from the fourth series of peer discussions on regulatory practices entitled D evelopment of measures to assess the safety of existing nuclear power plants and the effectiveness of regulations and regulatory actions (including 'prescriptive' and 'performance based' approaches) . Senior regulators from 23 Member States participated in four peer group discussions during 1995-1996. This report presents the outcome of these meetings and recommendations of good practices identified by these senior regulators. The purpose of this report is to disseminate the views which the senior regulators presented at the meetings relating to measures used for assessing the safety of existing nuclear power plants and evaluating the effectiveness of regulators and regulatory actions. The intention in doing this is to assist Member States in the enhancement of their regulatory practices by identifying commonly accepted good practices. This report is structured so that it covers the subject matter under the following main headings: 'Prescriptive and Performance Based' Approaches to Regulation; Common Features of Regulatory Approaches; Effectiveness of the Regulator and Regulatory Actions; Recommendations of Good Practice. It is important to note that recommendations of good practice are included if they have been identified by at least one of the groups. It does not follow that all of the groups or individual Member States would necessarily endorse all of the recommendations. However, it is considered that if a single group of senior regulators judge that a particular practice is worthy of recommendation then it should be included for serious consideration. In some cases the same recommendations arise from all of the Groups

Anti-regulatory T cells

responses to tumours or inhibiting autoimmunity development. However, recent studies report the discovery of self-reactive pro-inflammatory T cells—termed anti-regulatory T cells (anti-Tregs)—that target immune-suppressive cells. Thus, regulatory cells can now be defined as both cells that suppress immune...... reactions as well as effector cells that counteract the effects of suppressor cells and support immune reactions. Self-reactive anti-Tregs have been described that specifically recognize human leukocyte antigen-restricted epitopes derived from proteins that are normally expressed by regulatory immune cells......Our initial understanding of immune-regulatory cells was based on the discovery of suppressor cells that assure peripheral T-cell tolerance and promote immune homeostasis. Research has particularly focused on the importance of regulatory T cells (Tregs) for immune modulation, e.g. directing host...

EFFECTS OF HISTONE DEACETYLASE INHIBITOR, SAHA, ON EFFECTOR AND FOXP3+ REGULATORY T CELLS IN RHESUS MACAQUES

SAHA, a histone deacetylase inhibitor (HDACi), is clinically approved for treatment of cutaneous T-cell lymphoma. Although the exact underlying mechanisms are unknown, HDACi arrest the cell cycle in rapidly proliferating tumor cells and promote their apoptosis. HDACi were also recently shown to enhance the production and suppressive functions of Foxp3+ regulatory T (Treg) cells in rodents, leading us to begin to investigate the actions of HDACi on rhesus monkey T cells for the sake of potential preclinical applications. In this study, we show that SAHA inhibits polyclonal activation and proliferation of rhesus T cells and that the anti-proliferative effects are due to inhibition of T effector (Teff) cells and enhancement of Treg cells. Cryopreserved rhesus macaque splenocytes were CFSE labeled, stimulated with anti-CD3/anti-CD28 and cultured for 5 days in the presence of varying concentrations of SAHA. Samples were then co-stained to evaluate CD4 and CD8 expression. 10 and 5μM concentrations of SAHA were toxic to splenocytes. Proliferation was inhibited by 57% in CD4 cells and 47% in CD8 cells when unseparated splenocytes were cultured with 3 μM SAHA. Effector cells alone showed a decreased inhibition to proliferation when cultured with 3 μM and 1 μM SAHA when compared to Teff plus Treg cells. Our data suggest that SAHA can be used as part of an immunosuppressive protocol to enhance graft survival by limiting Teff cell proliferation as well as increasing Treg cells, thereby promoting tolerance.

Assessing progress in the development of safety culture

International Nuclear Information System (INIS)

Rotaru, I.; Ghita, S.; Biro, L.

2002-01-01

This paper is focussed on the organizational culture and learning processes required for the implementation of all aspects of safety culture. There is no prescriptive formula for improving safety culture. However, some common characteristics and practices are emerging that can be adopted by organizations in order to make progress. The paper refers to some approaches that have been successful in a number of countries. The experience of the international nuclear industry in the development and improvement of safety culture could be extended and found useful in other nuclear activities, irrespective of scale. The examples given of specific practice cover a wide range of activities including analysis of events, the regulatory approach on safety culture, employee participation and safety performance measures. Many of these practices may be relevant to smaller organizations and could contribute to improving safety culture, whatever the size of the organization. The most effective approach is to pursue a range of practices that can be mutually supportive in the development of a progressive safety culture, supported by professional standards, organizational and management commitment. Some guidance is also given on the assessment of safety culture and on the detection of a weakening safety culture. Few suggestions for accelerating the safety culture development and improvement process are also provided. (author)

The Regulatory Effects of Long Noncoding RNA-ANCR on Dental Tissue-Derived Stem Cells

Directory of Open Access Journals (Sweden)

Qian Jia

2016-01-01

Full Text Available Long noncoding RNAs (lncRNA have been recognized as important regulators in diverse biological processes, such as transcriptional regulation, stem cell proliferation, and differentiation. Previous study has demonstrated that lncRNA-ANCR (antidifferentiation ncRNA plays a key role in regulating the proliferation and osteogenic differentiation of periodontal ligament stem cells (PDLSCs. However, little is known about the role of ANCR in regulating other types of dental tissue-derived stem cells (DTSCs behaviours (including proliferation and multiple-potential of differentiation. In this study, we investigated the regulatory effects of lncRNA-ANCR on the proliferation and differentiation (including osteogenic, adipogenic, and neurogenic differentiation of DTSCs, including dental pulp stem cells (DPSCs, PDLSCs, and stem cells from the apical papilla (SCAP by downregulation of lncRNA-ANCR. We found that downregulation of ANCR exerted little effect on proliferation of DPSCs and SCAP but promoted the osteogenic, adipogenic, and neurogenic differentiation of DTSCs. These data provide an insight into the regulatory effects of long noncoding RNA-ANCR on DTSCs and indicate that ANCR is a very important regulatory factor in stem cell differentiation.

Safety Culture for Regulator Competence Management in Embarking States

Kandil, M.

2016-01-01

Full text: Safety is based on preventive actions where the ability of a regulatory body to fulfill its responsibilities depends largely on the competence of its staff. Building employees’ skills and knowledge is an investment for each employee and in the future of the organization. This building must be the competence of its staff integration with their safety culture, the essential to ensure competent human resources as required in the IAEA safety standards and other documents, in which the need and importance of ensuring regulatory competence is emphasized. As it involves both operational and management issues, safety culture is a sensitive topic for regulators whose role is to ensure compliance with safety requirements and not to intervene in management decisions. A number of embarking States are aspiring to develop nuclear power generation and this means that, among other things, regulatory bodies have to be established and rapidly expanded. This paper reports major considerations on the integration of safety culture with an adequate competence management system for regulators in embarking states. (author

Cross-Cultural Effects of Cannabis Use Disorder: Evidence to Support a Cultural Neuroscience Approach.

Science.gov (United States)

Prashad, Shikha; Milligan, Amber L; Cousijn, Janna; Filbey, Francesca M

2017-06-01

Cannabis use disorders (CUDs) are prevalent worldwide. Current epidemiological studies underscore differences in behaviors that contribute to cannabis use across cultures that can be leveraged towards prevention and treatment of CUDs. This review proposes a framework for understanding the effects of cross-cultural differences on psychological, neural, and genomic processes underlying CUDs that has the potential to inform global policies and impact global public health. We found that cultural factors may influence (1) the willingness to acknowledge CUD-related symptoms among populations of different countries, and (2) neural responses related to the sense of self, perception, emotion, and attention. These findings leverage the potential effects of culture on neural mechanisms underlying CUDs. As the number of individuals seeking treatment for CUDs increases globally, it is imperative to incorporate cultural considerations to better understand and serve differing populations and develop more targeted treatment strategies and interventions.

Regulatory control of the use of contractors by operating organizations. Peer discussions on regulatory practices

International Nuclear Information System (INIS)

2000-09-01

This report arises from the eighth series of peer discussions on regulatory practices entitled 'Regulatory control of the use of contractors by operating organizations'. Senior regulators from 19 Member States participated in two peer group discussions in March 2000 and May 2000. This report gives an account of the outcomes of these meetings and of practical suggestions put forward by senior regulators. These suggestions do not necessarily reflect the views of the governments of the nominating Member States, the organizations they belong to, or the International Atomic Energy Agency. The objective of this document is to share experience between regulatory bodies and provide practical suggestions for controlling the use of contractors and subcontractors by the operating organizations during all stages, especially operation, of a nuclear power plant, so as to ensure that the quality of work and services delivered is commensurate with the safety importance of the activities and that these are carried out in a manner that will not adversely affect the safe or reliable operation of the facility. These documented practical suggestions and experiences are the result of a series of peer discussions at the IAEA in 2000. It is considered that the manner in which control is exercised, and the various challenges connected to this control, are highly dependent upon the legislative framework, maturity of the nuclear programme, the size of the national nuclear industry and the culture in each country. The report is structured so that it covers the subject matter under the following main headings: Legal Provisions, Regulatory Strategy and Requirements; Regulatory Approaches for Controlling the Use of Contractors; Types of Contracts; Practical Suggestions

Endothelial cells stimulate growth of normal and cancerous breast epithelial cells in 3D culture

Directory of Open Access Journals (Sweden)

Magnusson Magnus K

2010-07-01

Full Text Available Abstract Background Epithelial-stromal interaction provides regulatory signals that maintain correct histoarchitecture and homeostasis in the normal breast and facilitates tumor progression in breast cancer. However, research on the regulatory role of the endothelial component in the normal and malignant breast gland has largely been neglected. The aim of the study was to investigate the effects of endothelial cells on growth and differentiation of human breast epithelial cells in a three-dimensional (3D co-culture assay. Methods Breast luminal and myoepithelial cells and endothelial cells were isolated from reduction mammoplasties. Primary cells and established normal and malignant breast cell lines were embedded in reconstituted basement membrane in direct co-culture with endothelial cells and by separation of Transwell filters. Morphogenic and phenotypic profiles of co-cultures was evaluated by phase contrast microscopy, immunostaining and confocal microscopy. Results In co-culture, endothelial cells stimulate proliferation of both luminal- and myoepithelial cells. Furthermore, endothelial cells induce a subpopulation of luminal epithelial cells to form large acini/ducts with a large and clear lumen. Endothelial cells also stimulate growth and cloning efficiency of normal and malignant breast epithelial cell lines. Transwell and gradient co-culture studies show that endothelial derived effects are mediated - at least partially - by soluble factors. Conclusion Breast endothelial cells - beside their role in transporting nutrients and oxygen to tissues - are vital component of the epithelial microenvironment in the breast and provide proliferative signals to the normal and malignant breast epithelium. These growth promoting effects of endothelial cells should be taken into consideration in breast cancer biology.

When planning is not enough: the self-regulatory effect of implementation intentions on changing snacking habits.

Science.gov (United States)

Tam, Leona; Bagozzi, Richard P; Spanjol, Jelena

2010-05-01

This study examined whether matching implementation intentions to people's regulatory orientation affects the effectiveness of changing unhealthy snacking habits. Participants' regulatory orientation was either measured (as a chronic trait) or manipulated (as a situational state), and participants were randomly assigned to implementation intention conditions to eat more healthy snacks or avoid eating unhealthy ones. A self-reported online food diary of healthy and unhealthy snacks over a 2-day period. Participants with weak unhealthy snacking habits consumed more healthy snacks when forming any type of implementation intentions (regardless of match or mismatch with their regulatory orientation), while participants with strong unhealthy snacking habits consumed more healthy snacks only when forming implementation intentions that matched their regulatory orientations. RESULTS suggest that implementation intentions that match regulatory orientation heighten motivation intensity and put snacking under intentional control for people with strong unhealthy snacking habits.

Choe, Daniel Ewon; Sameroff, Arnold J.; McDonough, Susan C.

2013-01-01

This longitudinal study of 251 families examined bidirectional associations between maternal depressive symptoms and toddler behavioral problems. Functional regulatory problems in infancy and gender were examined as moderators. Mothers rated children’s regulatory problems of crying, feeding, and sleeping in infancy, toddler-age externalizing behavior, and their own depressive symptoms when children were ages 7, 15, and 33 months. Using a structural equation model we found that exposure to maternal depressive symptoms at 7 months predicted high levels of child externalizing behavior at 15 and 33 months. Gender moderated the effect, such that maternal depressive symptoms only predicted boys’ externalizing behavior at 33 months. Toddler-age externalizing behavior predicted high levels of maternal depressive symptoms at 33 months, only among those who had relatively few regulatory problems as infants. Infancy seems to be a period of heightened vulnerability to effects of maternal depression and boys are more likely than girls to develop resulting externalizing problems. Mothers of infants with few regulatory problems may develop worse depressive symptoms in response to their children’s preschool-age behavioral problems. PMID:23545078

Xylogenesis in zinnia (Zinnia elegans) cell cultures: unravelling the regulatory steps in a complex developmental programmed cell death event.

Science.gov (United States)

Iakimova, Elena T; Woltering, Ernst J

2017-04-01

Physiological and molecular studies support the view that xylogenesis can largely be determined as a specific form of vacuolar programmed cell death (PCD). The studies in xylogenic zinnia cell culture have led to many breakthroughs in xylogenesis research and provided a background for investigations in other experimental models in vitro and in planta . This review discusses the most essential earlier and recent findings on the regulation of xylem elements differentiation and PCD in zinnia and other xylogenic systems. Xylogenesis (the formation of water conducting vascular tissue) is a paradigm of plant developmental PCD. The xylem vessels are composed of fused tracheary elements (TEs)-dead, hollow cells with patterned lignified secondary cell walls. They result from the differentiation of the procambium and cambium cells and undergo cell death to become functional post-mortem. The TE differentiation proceeds through a well-coordinated sequence of events in which differentiation and the programmed cellular demise are intimately connected. For years a classical experimental model for studies on xylogenesis was the xylogenic zinnia (Zinnia elegans) cell culture derived from leaf mesophyll cells that, upon induction by cytokinin and auxin, transdifferentiate into TEs. This cell system has been proven very efficient for investigations on the regulatory components of xylem differentiation which has led to many discoveries on the mechanisms of xylogenesis. The knowledge gained from this system has potentiated studies in other xylogenic cultures in vitro and in planta. The present review summarises the previous and latest findings on the hormonal and biochemical signalling, metabolic pathways and molecular and gene determinants underlying the regulation of xylem vessels differentiation in zinnia cell culture. Highlighted are breakthroughs achieved through the use of xylogenic systems from other species and newly introduced tools and analytical approaches to study the

Time perspective and social preference in older and younger adults: Effects of self-regulatory fatigue.

Science.gov (United States)

Segerstrom, Suzanne C; Geiger, Paul J; Combs, Hannah L; Boggero, Ian A

2016-09-01

Socioemotional selectivity theory predicts that when perceived time in life is limited, people will prefer emotionally close social partners over less emotionally rewarding partners. Regulating social choices with regard to time perspective can make the best use of time with regard to well-being. However, doing so may depend on the self-regulatory capacity of the individual. Two studies, 1 with younger adults (N = 101) and 1 with younger (N = 42) and older (N = 39) adults, experimentally tested the effects of time perspective and self-regulatory fatigue on preferences for emotionally close partners and knowledgeable partners. In both studies and across younger and older adults, when self-regulatory fatigue was low, the perception of limited time resulted in a greater preference for close social partners relative to knowledgeable social partners. However, this shift was eliminated by self-regulatory fatigue. In Study 2, when fatigued, younger adults preferred close social partners to knowledgeable partners across time perspectives; older adults preferred close and knowledgeable partners more equally across time perspectives. These findings have implications for social decision-making and satisfaction among people who experience chronic self-regulatory fatigue. They also contradict previous suggestions that only younger adults are susceptible to self-regulatory fatigue. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Regulatory approach of the monitoring the effectiveness of maintenance at nuclear power plants program

International Nuclear Information System (INIS)

Vajgel, Stefan

2009-03-01

The electrical power generation using nuclear power plants requires this installation being safety, reliable and available for the working periods. For this purpose, an adequate, effective and well conducted maintenance program makes an essential and useful tool to the owner of the plant. However, it is necessary to follow the regulatory requirements for this program implementation which monitories this maintenance effectiveness. There are Brazilian norms requirements which must be followed. The international regulatory guides establish these requirements in good details but it is necessary to verify if this methodology for implementing can be totally applied here in Brazil. Then, the american guide NUMARC 93-01 which details how can be implemented a program for this monitoring, shows some methods for using. In this thesis, the Delphi and Probabilistic Safety Analysis were briefly included because they were preferred for implementing this monitoring.in a Brazilian plant. The results which are being obtained show that, looking the regulatory aspects, the NUMARC 93-01 follows our regulations and gives good results for the plant management. (author)

Adapting to an initial self-regulatory task cancels the ego depletion effect.

Science.gov (United States)

Dang, Junhua; Dewitte, Siegfried; Mao, Lihua; Xiao, Shanshan; Shi, Yucai

2013-09-01

The resource-based model of self-regulation provides a pessimistic view of self-regulation that people are destined to lose their self-control after having engaged in any act of self-regulation because these acts deplete the limited resource that people need for successful self-regulation. The cognitive control theory, however, offers an alternative explanation and suggests that the depletion effect reflects switch costs between different cognitive control processes recruited to deal with demanding tasks. This account implies that the depletion effect will not occur once people have had the opportunity to adapt to the self-regulatory task initially engaged in. Consistent with this idea, the present study showed that engaging in a demanding task led to performance deficits on a subsequent self-regulatory task (i.e. the depletion effect) only when the initial demanding task was relatively short but not when it was long enough for participants to adapt. Our results were unrelated to self-efficacy, mood, and motivation. Copyright © 2013 Elsevier Inc. All rights reserved.

Ikaros, a transcription factor containing zinc-finger motif, has known as a critical regulator of hematopoiesis in immune system. Ikaros protein modulates the transcription of target genes via binding to the regulatory elements of the genes promoters. However the regulatory function of Ikaros in other organelle except nuclear remains to be determined. This study explored radiation-induced modulatory function of Ikaros in cytoplasm. The results showed that Ikaros protein lost its DNA binding ability after LDIR (low-dose ionizing radiation) exposure. Cell fractionation and Western blot analysis showed that Ikaros protein was translocated into cytoplasm from nuclear by LDIR. This was confirmed by immunofluorescence assay. We identified Autotaxin as a novel protein which potentially interacts with Ikaros through in vitro protein-binding screening. Co-immunoprecipitation assay revealed that Ikaros and Autotaxin are able to bind each other. Autotaxin is a crucial enzyme generating lysophosphatidic acid (LPA), a phospholipid mediator, which has potential regulatory effects on immune cell growth and motility. Our results indicate that LDIR potentially regulates immune system via protein-protein interaction of Ikaros and Autotaxin.

Virginia Power's regulatory reduction program

International Nuclear Information System (INIS)

Miller, G.D.

1996-01-01

Virginia Power has two nuclear plants, North Anna and Surry Power Stations, which have two units each for a total of four nuclear units. In 1992, the Nuclear Regulatory Commission solicited comments from the nuclear industry to obtain their ideas for reducing the regulatory burden on nuclear facilities. Pursuant to the new regulatory climate, Virginia Power developed an internal program to evaluate and assess the regulatory and self-imposed requirements to which they were committed, and to pursue regulatory relief or internal changes where possible and appropriate. The criteria were that public safety must be maintained, and savings must be significant. Up to the date of the conference, over US$22 million of one-time saving had been effected, and US$2.75 million in annual savings

Self-efficacy and the use of self-regulatory strategies are consistently associated with physical activity behavior. Similarly, behavioral inhibition and cognitive resource allocation-indices of executive control function-have also been associated with this health behavior. The purpose of this study was to examine the hypothesis that self-efficacy mediates the relationship between self-regulatory processes, such as executive function, and sustained exercise behavior. Older adults (N=177, mean age=66.44 years) completed measures of executive function, self-reported use of self-regulatory strategies, and self-efficacy prior to and during the first month of a 12-month exercise intervention. Percentage of exercise classes attended over the following 11 months was used to represent adherence. Data were collected from 2007 to 2010 and analyzed in 2010-2011. Structural equation models were tested examining the effect of executive function and strategy use on adherence via efficacy. As hypothesized, results showed significant direct effects of two elements of executive function and of strategy use on self-efficacy and of efficacy on adherence. In addition, there were significant indirect effects of strategy use and executive function on adherence via self-efficacy. Higher levels of executive function and use of self-regulatory strategies at the start of an exercise program enhance beliefs in exercise capabilities, which in turn leads to greater adherence.

2014-01-01

Through its interaction with the American industry, the NRC has been aware for a number of years of the concern about the impact of the accumulative effect of some regulatory actions. In response to this concern, which was highlighted by the industry, the NRC has carried out initiative to review a number of regulatory requirements order to ensure that NRC regulation and practices dno not lead to an unnecessary regulatory load. The foregoing was in response to what has become commonly known as the CER. Cumulative Effects of Regulation in the Rulemaking Process. In view of the regulatory actuation by the Spanish Nuclear Safety Council (CSN) and, in particular after the events which occurred in Japan, a pilot study has been carried out to examine the CER on a Spanish plant in order to analyse the cumulative effects of regulation and to propose improvements to the management of regulation in line with that set our by the NRC in various documents (SECY-02-081, SECY-11-0032 among others).

Partridge, J.W. Jr.

1993-01-01

Federal Energy Regulatory Commission (FERC) Orders 436, 500, and 636, the Clean Air Act Amendments of 1990, Public Utility Holding Company Act reform, and the 1992 Energy Policy Act all can have significant effects on an LDC's operations. Such changes in an LDC's environments must be balanced by changes within the utility, its marketplace, and its state regulatory environment. The question is where to start. For Columbia Gas Distribution Cos., based in Columbus, OH, the new operating foundation begins with each employee. Internal strength is critical in designing initiatives that meet the needs of the marketplace and are well-received by regulators. Employees must understand not only the regulatory environment in which the LDC operates, but also how their work contributes to a positive regulatory relationship. To achieve this, Columbia initiated the COntinuing Regulatory Education program, or CORE, in 1991. CORE is a regulatory-focused, information-initiative program coordinated by Columbia's Regulatory Policy, Planning, and Government Affairs Department. The CORE programs can take many forms, such as emerging issue discussions, dialogues with regulators and key parties, updates on regulatory fillings, regulatory policy meetings, and formal training classes. The speakers and discussion facilitators can range from human resource department trainers to senior officers, from regulatory department staff members to external experts, or from state commissioners to executives from other LDCs. The goals of CORE initiatives are to: Support a professional level of regulatory expertise through employee participation in well-developed regulatory programs presented by credible experts. Encourage a constructive state regulatory environment founded on communication and cooperation. CORE achieves these goals via five program levels: introductory basics, advanced learning, professional expertise, crossfunctional dialogues, and external idea exchanges

The Hungarian Atomic Energy Authority (HAEA) in 2014 carried out a self-assessment in order to preparation for IAEA IRRS mission. As a result of the SWOT analysis it was concluded that for the promotion, development and improvement of safety culture at the HAEA is displayed only on the policy level. In order to obtain a greater emphasis on safety culture within the organization a working group was created. The task of the working group was to define the proposed actions to develop the organizational safety culture. The working group reviewed the current situation, the international experiences and proposed on this basis the elaboration of a guideline regarding to organizational safety culture, to integrate this guideline into the organizational training program so as to apply to all levels of the organization and presentation of the safety culture as part of the training of new comers. Results so far: The working group has defined the main tasks and the connecting milestones in order to develop and improve the organizational safety culture at the HAEA. HAEA has elaborated a guideline for performing safety culture self-assessment based on IAEA and other relevant documents.

Quality management of the nuclear regulatory body. Peer discussions on regulatory practices

International Nuclear Information System (INIS)

2001-09-01

This report is the outcome of the ninth series of peer discussions on regulatory practices entitled Nuclear Regulatory Body Quality Management, held in March and May 2001, and which involved the participation of senior nuclear regulators from 23 IAEA Member States. This report conveys the essence of two peer group discussions and highlights some good practices identified by the participating senior regulators. The objective of the discussions was to share experiences of regulatory bodies in implementing QM systems in their own work so as to ensure that the regulatory control over the licensees is effective and efficient and is commensurate with the mandate assigned by their governments. The shared experiences and good practices presented in the report, however, do not necessarily reflect the views of and good practices endorsed by the governments of the nominating Member States, the organizations to which the regulators belong, or the IAEA. The report sets down the peer group's experience in developing, implementing and evaluating QM within their regulatory bodies and identifies points to bear in mind when introducing such a system. This report is structured so that it covers the subject matter under the main headings of: application of quality management to regulatory work; development and implementation of quality management; assessment and improvement of performance; and good practices

Effect of Telecollaboration on Translation of Culture-Bound Texts

Full Text Available One of the most problematic perspectives of translation phenomenon is the cultural gap between the source language and the target language (Yang, 2010. This gap can be ideally filled through telecollaboration which provides internationally dispersed language learners in parallel language classes with cost-effective access to, and engagement with, peers who are expert speakers of the language under study (Belz, 2005. To investigate the effect of telecollaboration on the quality of translation of culture-bound texts, the current study was conducted on 64 Iranian undergraduate students of English translation at a university in Iran. Instruments used in the study consisted of three texts containing news excerpts from Voice of America (VOA. The study consisted of three phases: 1 assessing quality of translation of culture-bound texts, 2 random assignment of participants to two groups: one merely receiving cultural instruction while the other being linked to native English speakers through LinkedIn alongside receiving cultural instruction, and 3 assessing quality of translation of culture-bound texts immediately and two months following treatment. The results of mixed between-within subjects analysis of variance revealed the significant positive effect of telecollaboration on developing quality of translation of culture-bound texts and sustaining the attained knowledge. The pedagogical implications of the findings suggested incorporation of cultural components of source language society into translation courses and providing opportunities for translation students to be exposed to authentic and intensive source language culture through telecollaboration.

The Role of Cultural Compatibility in Effective Management The Application of Cultural Four-dimensional Model in Transnational Corporations

2015-01-01

Cross-cultural management is often regarded as a discipline of international management focusing on cultural encounters between the organization and the nation-state, and providing tools to tackle cultural difl＇erences seen as sources of conflict, friction or misunderstanding. Based on Greet Hofstede＇ s Cultural Model, this paper attempts to shed some light on effective corporation management through cultural analysis of the difl＇erences between China and western countries. The paper puts more emphasis on the impact of cultural compatibility on effective corporation man- agement through the case study of China, Japan, Germany and America. The author argues that managers and employ- ees involved in companies with diverse cultural backgrounds should be integrated and developed into a specific local context through interlocking their cultural identifications and the organizational practices.

Tripathi, Prateek; Rabara, Roel C.; Lin, Jun; Rushton, Paul J.

2013-01-01

Drought is the major cause of crop losses worldwide. Water stress-inducible promoters are important for understanding the mechanisms of water stress responses in crop plants. Here we utilized tobacco (Nicotiana tabacum L.) Bright Yellow 2 (BY-2) cell system in presence of polyethylene glycol, salt and phytohormones. Extension of the system to 85 mM NaCl led to inducibility of up to 10-fold with the water stress and salt responsive soybean GmWRKY53 promoter. Upon ABA and JA treatment fold inducibility was up to 5-fold and 14-fold, respectively. Thus, we hypothesize that GmWRKY53 could be used as potential model candidate for dissecting drought regulatory elements as well as understanding crosstalk utilizing a rapid heterologous system of BY-2 culture.

Reiman, T.; Norros, L.

2001-03-01

A case study to investigate the organisational culture of the regulatory authority was conducted at the Radiation and Nuclear Safety Authority of Finland's (STUK) Nuclear Reactor Regulation (YTO) - department. Organisational culture is defined as a pattern of shared basic assumptions, which are basically unconscious. Objectives of the study were to conceptualise and describe the main characteristics of YTO's organisational culture and to carry out a tentative core task analysis of the inspectors' work. A combination of quantitative and qualitative methods was used in the research. YTO's culture was identified as a hierarchy-focused culture with less emphasis on innovation or social support. However, the ideal values of the personnel emphasised also social support and goal setting. Ambiguous goals were felt by some personnel as increased uncertainty about the meaningfulness of one's job. Also a lack of feedback was mentioned. The core task analysis identified the critical functions of the regulatory practice. These functions specify the three roles of the regulatory authority, the expert role, the public role and the authority role. The culture must support the fulfilment of the requirements of all the three roles. Development needs in YTO's culture were identified and recommendations were made. (au)

The Republic of Namibia is participating in the International Atomic Energy Agency's Model Project for the Improvement of National Regulatory Authority Infrastructures in Member States. The paper illustrates our experience in solving problems and difficulties confronted in establishing an effective regulatory authority operating within the existing national infrastructure that should be supported by the Government. An effective regulatory authority is seen as part of the wider administrative scope of our Government through ministerial mandates given by the State from time to time, guaranteeing its independence when implementing legal provisions under statutes. Sections of the report illustrate our experience in the following areas: 1. National radiation protection policy 2. Structure of our national regulatory authority 3. Laws and regulations 4. Provisions for notification, authorization and registration 5. In-depth security measures for radiation sources and radioactive material 6. Systems for the inspection of radiation sources, radioactive materials, enforcement of legal provisions 7. Extent of the applications of radiation sources and radioactive materials in the country. The paper provides information regarding existing Government policy on radiation protection; structure and legal aspects of the national regulatory, including statutes and regulations; the extent of application and uses of radiation sources and security of radioactive materials; human resources: strengths and constraints; management practices and financing of regulatory authority; and plans for emergency recovery of orphan sources. National plans for management of disused sources, recovery of orphan sources, abnormal emergencies, communication of information to affected persons on exposure effects, and the safety training of persons using these applications are discussed. the paper provides a summary and some suggestions of the way forward for Namibia.

2015-10-01

Full Text Available In order to increase their markets, many companies are starting e-commerce internationalization processes that involve dealing with cultural differences among countries. Although most firms start internationalization strategies to similar countries, previous research has mainly focused on understanding expansion to countries with a great cultural distance. This study analyzes the relevance of culture in the formation of e-loyalty intentions in Argentina and Spain, two countries with slight cultural differences. Specifically, culture is proposed as a moderator of e-service quality and satisfaction effects on e-loyalty intentions. Results confirm that the influence of e-service quality on e-loyalty intentions is greater for Argentinian consumers (a little more individualistic, masculine, and less pragmatic culture compared to Spain. Besides, a greater influence of satisfaction on e-loyalty is found for Spanish consumers (a more pragmatic, collectivistic, and feminine culture compared to Argentina. The introduction of socio-demographic control variables, i.e. gender, age and education level, support the moderation effect of culture. According to these results, marketers should note that e-loyalty formation process differs across cultures, even between similar cultures. Further implications for international marketing strategies are widely discussed.

Nuclear regulatory decision making

International Nuclear Information System (INIS)

2005-01-01

The fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear utilities operate their plants at all times in an acceptably safe manner. In meeting this objective, the regulatory body should strive to ensure that its regulatory decisions are technically sound, consistent from case to case, and timely. In addition, the regulator must be aware that its decisions and the circumstances surrounding those decisions can affect how its stakeholders, such as government policy makers, the industry it regulates, and the public, view it as an effective and credible regulator. In order to maintain the confidence of those stakeholders, the regulator should make sure that its decisions are transparent, have a clear basis in law and regulations, and are seen by impartial observers to be fair to all parties. Based on the work of a Nuclear Energy Agency (NEA) expert group, this report discusses some of the basic principles and criteria that a regulatory body should consider in making decisions and describes the elements of an integrated framework for regulatory decision making.

A strategy for regulatory action when new adverse effects of a licensed product emerge.

Science.gov (United States)

Aronson, Jeffrey K; Price, Deirdre; Ferner, Robin E

2009-01-01

Regulatory agencies grant product licences (marketing authorizations) for medicinal products in the light of evidence that the balance between benefit and harm in the population is favourable. Here we consider a framework for allowing regulatory agencies to make rational decisions when reviewing product licences in the light of new information about harms that change that balance. The regulator can revoke the product licence, restrict the product's availability or change the 'label' in different ways. We examine the features of the adverse effect that may be relevant in making the decision: namely, individual differences in susceptibility; the possibility of monitoring; and the availability of protective strategies. The balance of benefit and harm, and the time-course and dose relation of the adverse effect play important roles in the decision-making process. We set out how these factors can help determine the logical response to new information on the balance between benefit and harm, and provide a series of relevant examples. We believe that when regulatory agencies have to decide how to amend the product licence of a drug when new serious adverse effects cause concern, they would find it useful to adopt a framework of this kind, using different strategies for different cases. Our proposed framework could also be useful in risk management planning during drug development.

The effectiveness of the regulatory activity in matter of safety and radiological protection it depends in great measure of the practical implementation level of the legislation in this matter. In our country this objective has been achieved through the one continuous improvement of the Hierarchical System of Nuclear Regulation, the reconciliation with specialists and national experts in each matter during the elaboration of the legal documents; the popularization and gratuitous distribution of it approved; the precision in the validation conditions of the authorizations of those main precepts applicable to the practices; the legal foundation of the deficiencies evidenced in the regulatory inspections; the development of a Safety Culture; the realization of Annual Regulatory Conferences and mainly in the training of the personnel related with the safety. Also, the constant analysis on the part of the specialists of the Regulatory Authority of the grade of implementation of this legislation, it discussion in national and international events and the actions recommended in these works. As a result of this focus, it is considered that the Regulatory Authority has impacted appropriately in the implementation of this legislation. (Author)

Extraordinary sex ratios: cultural effects on ecological consequences.

Directory of Open Access Journals (Sweden)

Ferenc Molnár

Full Text Available We model sex-structured population dynamics to analyze pairwise competition between groups differing both genetically and culturally. A sex-ratio allele is expressed in the heterogametic sex only, so that assumptions of Fisher's analysis do not apply. Sex-ratio evolution drives cultural evolution of a group-associated trait governing mortality in the homogametic sex. The two-sex dynamics under resource limitation induces a strong Allee effect that depends on both sex ratio and cultural trait values. We describe the resulting threshold, separating extinction from positive growth, as a function of female and male densities. When initial conditions avoid extinction due to the Allee effect, different sex ratios cannot coexist; in our model, greater female allocation always invades and excludes a lesser allocation. But the culturally transmitted trait interacts with the sex ratio to determine the ecological consequences of successful invasion. The invading female allocation may permit population persistence at self-regulated equilibrium. For this case, the resident culture may be excluded, or may coexist with the invader culture. That is, a single sex-ratio allele in females and a cultural dimorphism in male mortality can persist; a low-mortality resident trait is maintained by father-to-son cultural transmission. Otherwise, the successfully invading female allocation excludes the resident allele and culture and then drives the population to extinction via a shortage of males. Finally, we show that the results obtained under homogeneous mixing hold, with caveats, in a spatially explicit model with local mating and diffusive dispersal in both sexes.

Insight and Lessons Learned on Safety Culture from Analysis of Inspection Findings and Events

Kim, J.T.; Jung, S.J.; Choi, Y.S.

2016-01-01

Safety culture has been a main subject of scrutiny in major accidents of modern complex technologies. The Fukushima accident also plausibly has its root cause deep into weak safety culture. After the Fukushima accident in Japan 2011, many critics have searched for cultural factors that caused the unacceptable negligence pervaded in Japan’s nuclear society. Renewed emphasis has also been placed on rebuilding strong safety culture by operators, regulators, and relevant institutions worldwide. Significant progress has been made in approach to safety culture and this led to a new perspective different from the existing normative assessment method both in operators and regulatory side. Regulatory expectations and oversight of them are based on such a new holistic concept for human, organizational and cultural elements to maintain and strengthen the integrity of defense in depth and consequently nuclear safety.

Parent socialization effects in different cultures: significance of directive parenting.

Science.gov (United States)

Sorkhabi, Nadia

2012-06-01

In this article, the controversy of divergent findings in research on parental socialization effects in different cultures is addressed. Three explanations intended to address divergent findings of socialization effects in different cultures, as advanced by researchers who emphasize cultural differences, are discussed. These include cultural differences in socialization values and goals of parents, parental emotional and cognitive characteristics associated with parenting styles, and adolescents' interpretations or evaluations of their parents' parenting styles. The empirical evidence for and against each of these arguments is examined and an alternative paradigm for understanding and empirical study of developmental outcomes associated with parenting styles in different cultures is suggested. Baumrind's directive parenting style is presented as an alternative to the authoritarian parenting style in understanding the positive developmental effects associated with "strict" parenting in cultures said to have a collectivist orientation. Directions for research on the three explanations are mentioned.

There is a widespread belief that safety culture is an important contributor to safety of operations. The commonly accepted attributes of safety culture include good organizational communications, good organizational learning, and senior management commitment to safety. Safety culture may be particularly important in reducing latent errors in complex, well-defended systems. The role of regulatory bodies in fostering strong safety cultures remains unclear, and additional work is required to define the essential attributes of safety culture and to identify reliable performance indicators.

Cultural Transmission on the Taskscape: Exploring the Effects of Taskscape Visibility on Cultural Diversity.

Science.gov (United States)

Premo, L S; Tostevin, Gilbert B

2016-01-01

Culturally transmitted behavior can be structured in its performance both geographically and temporally, in terms of where and when implements are made and used on the landscape (what Ingold calls "the taskscape"). Yet cultural transmission theory has not yet explored the consequences of behaviors transmitted differently due to their enactment at different taskscape locations, what Tostevin calls "taskscape visibility." Here, we use computer simulations to explore how taskscape visibility and forager mobility affect the diversity of two selectively neutral culturally transmitted traits within a single population of social learners. The trait that can be transmitted from residential bases only (lower taskscape visibility) shows greater diversity than the trait that can be transmitted from residential bases and logistical camps (higher taskscape visibility). In addition, increased logistical mobility has a positive effect on the diversity of the trait with the lower taskscape visibility while it generally shows little to no effect on the diversity of the trait with higher taskscape visibility. Without an appreciation for the ways in which taskscape visibility and mobility can structure cultural transmission in space and through time, the difference in the observed equilibrium diversity levels of the two traits might be incorrectly interpreted as resulting from qualitatively different forms of biased cultural transmission. The results of our simulation experiment suggest that researchers may need to take the taskscape visibility into account when inferring cultural transmission from archaeological data.

In its meeting in 1986, after Chernobyl accident, the INSAG group concluded, that the most important reason for the accident was lack of safety culture. Later the group realized that the safety culture, if it is well enough, can be used as a powerful tool to assess and develop practices affecting safety in any country. A comprehensive view on the various aspects of safety culture was presented in the INSAG-4 report published in 1991. Finland was among the first nations include the concept of safety culture in its regulations. This article describes the roles of government and the regulatory body in creating a national safety culture. How safety culture is seen in the operation of a nuclear power plant is also discussed.

Jones, Sandra C; Hall, Danika; Munro, Geoffrey

2008-01-01

Australia, like several other countries, has a self-regulatory approach to advertising. However, in recent years the effectiveness of the regulatory system has been questioned, and there have been increasing public calls for an overhaul of the system. Following a formal review in 2003, the Ministerial Council on Drug Strategy proposed a revised Alcoholic Beverages Advertising Code (ABAC), which came into operation in 2004. The purpose of the present study was to examine the effectiveness of this revised system. From May 2004 until March 2005 television and magazine advertising campaigns were monitored for alcohol products. Over this period 14 complaints against alcohol advertisements were lodged with the self-regulatory board, and the authors recruited an independent expert panel to assess the advertisements and complaints. In eight of the 14 cases a majority of the judges perceived the advertisement to be in breach of the code, and in no cases did a majority perceive no breach. Conversely, however, none of the complaints were upheld by the Advertising Standards Board (ASB) and only one by the ABAC Panel. The results of this study suggest that the decisions made by the ASB in relation to complaints against alcohol advertisements are not in harmony with the judgement of independent experts, and that the ASB may not be performing an adequate job of representing community standards or protecting the community from offensive or inappropriate advertisements. Further, it appears that the revisions to the ABAC code, and associated processes, have not reduced the problems associated with alcohol advertising in Australia.

Cultural effects on mindreading.

Perez-Zapata, Daniel; Slaughter, Virginia; Henry, Julie D

2016-01-01

People from other cultural backgrounds sometimes seem inscrutable. We identified a potential cause of this phenomenon in two experiments demonstrating that adults' mental state inferences are influenced by the cultural identity of the target. We adapted White, Hill, Happé, and Frith's (2009) Strange Stories to create matched intra-cultural and cross-cultural mindreading and control conditions. Experiment 1 showed that Australian participants were faster to respond and received higher scores in the intra-cultural mindreading condition relative to the cross-cultural mindreading condition, but performance in the control conditions was equivalent. Experiment 2 replicated this pattern in independent samples of Australian and Chilean participants. These findings have important implications for cross-cultural communication and understanding.

International Nuclear Safety Experts Conclude IAEA Peer Review of Korea's Regulatory System

International Nuclear Information System (INIS)

2011-01-01

, including: The Korean government, through the activities of MEST and KINS, has implemented a technically capable and effective nuclear safety regulatory program. KINS is an entrusted governmental corporation that functions as a nuclear safety regulation body. The team's findings note of the fact that the current Korean nuclear regulator is a combination of MEST and KINS; Transition to a new regulatory framework has the potential to enhance regulatory independence, expertise and transparency; however implementation details have yet to be finalized. Therefore, the team could not make a conclusion regarding the planned framework's effectiveness; and Korea's response to the accident at Fukushima has been prompt and effective. Communications with the public, development of actions for improvement and coordination with international stakeholders were of high quality. Among the good practices identified by the IRRS Review Team are the following: The regulatory body of Korea has a clear and structured national approach for nuclear safety; Korea strongly supports the global nuclear safety regime and provides training at national and international levels; KINS has a high level of technical competence and has implemented an effective human capital program; KINS performs detailed and comprehensive safety assessment using a broad range of deterministic and probabilistic codes and methods; and KINS has a comprehensive integrated computerized information and data management system. The IRRS Review Team identified certain issues warranting attention or in need of improvement and believes that consideration of these would enhance the overall performance of the future regulatory system. Transition to the new regulatory framework will require development of key implementation details that will impact the effectiveness of the new regulatory framework for safety; Enhancements to the management system in the areas of resource management, description of the internal safety culture, and

SCART guidelines. Reference report for IAEA Safety Culture Assessment Review Team (SCART)

International Nuclear Information System (INIS)

2008-01-01

The IAEA Director General stressed the role of safety culture in his concluding remarks at the Meeting of the Contracting Parties to the Convention on Nuclear Safety in 2002: 'As we have learned in other areas, it is not enough simply to have a structure; it is not enough to say that we have the necessary laws and the appropriate regulatory bodies. All these are important, but equally important is that we have in place a safety culture that gives effect to the structure that we have developed. To me, effectiveness and transparency are keys. So, it is an issue which I am pleased to see, you are giving the attention it deserves and we will continue to work with you in clarifying, developing and applying safety culture through our programmes and through our technical cooperation activities.' The concept of safety culture was initially developed by the International Nuclear Safety Advisory Group (INSAG) after the Chernobyl accident in 1986. Since then the IAEA's perspective of safety culture has expanded with time as its recognition of the complexities of the concept developed. Safety culture is considered to be specific organizational culture in all types of organizations with activities that give rise to radiation risks. The aim is to make safety culture strong and sustainable, so that safety becomes a primary focus for all activities in such organizations, even for those, which might not look safety-related at first. SCART (Safety Culture Assessment Review Team) is a safety review service, which reflects the expressed interest of Members States for methods and tools for safety culture assessment. It is a replacement for the earlier service ASCOT (Assessment of Safety Culture in Organizations Team). The IAEA Safety Fundamentals, Requirements and Guides (Safety Standards) are the basis for the SCART Safety Review Service. The reports of INSAG, identifying important current nuclear safety issues, serve also as references during a SCART mission. SCART missions are based

Full Text Available Objective. Investigation of hypolipidemic effect of sesquiterpene γ-lactone Arglabin in hepatoma tissue culture (HTC.Materials and methods. In this study we’ve evaluated the effect of sesquiterpene γ-lactone Arglabin and gemfibrozil (reference drug on the lipid content in the hepatoma tissue culture (HTC which were incubated with a fat emulsion “Lipofundin” by fluorescent method with vital dye Nile Red. The cell viability was investigated using the MTT-test and staining by Trypan blue.Results. Cultivation of cell cultures of rat’s hepatoma cell line HTC with Arglabin and gemfibrozil in concentrations from 10 to 50 μmol and from 0.25 to 0.5 mmol, respectively, had no cytotoxic effect. HTC cell viability did not change compared with the corresponding rate in the control culture. Experimental hyperlipidemia in hepatoma culture was induced by the addition in the incubation medium of fat emulsion “Lipofundin” in a final concentration of 0.05 %. The fluorescence intensity of Nile Red in the cells was increased 4-fold (p < 0.05, which indicates a significant accumulation of lipids in the cytosol of cells. In these steady-state Arglabin and gemfibrozil at concentrations 75–100 μM and 0.25–1.0 mM, respectively, reduced the content of lipid in cells. Conclusion. In the model of hyperlipidemia induced by lipofundin, sesquiterpene γ-lactone Arglabin prevents the accumulation of lipids in the HTC cell line, as evidenced by a decrease in Nile Red fluorescence. However hypolipidemic effect of Arglabin is associated with cytotoxic effects, which is typical for anticancer drugs.

'Statement of Nuclear Safety Policy' declared by the Korean Government elucidates adherence to the principle of 'priority to safety'. The 3. Comprehensive Nuclear Energy Promotion Plan (2007-2011) more specifically addressed the necessity to develop and apply 'safety culture evaluation criteria' and to strengthen safety management of concerned organizations in an autonomous way. Putting these policies as a backdrop, Korean Government has taken diverse safety culture initiatives and has encouraged the relevant organizations to develop safety culture practices of their own accord. Accordingly, KHNP, the operating organization in Korea, developed a 'safety culture performance indicator', which has been used to evaluate safety mind of employees and the evaluation results have been continuously reflected in operational management and training programs. Furthermore, KHNP inserted 'nuclear safety culture subject' into every course of more than two week length, and provided employees with special lectures on safety culture. KINS, the regulatory organization, developed indicators for the safety culture evaluation based on the IAEA Guidelines. Also, KINS has hosted an annual Nuclear Safety Technology Information Meeting to share information between regulatory organizations and industries. Furthermore, KINS provided a nuclear safety culture class to the new employees and they are given a chance to participate in performance of a role-reversal socio-drama. Additionally, KINS developed a safety culture training program, published training materials and conducted a 'Nuclear Safety Culture Basic Course' in October 2007, 4 times of which are planed this year. In conclusion, from Government to relevant organizations, 'nuclear safety culture' concept is embraced as important and has been put into practice on a variety of forms. Specifically, 'education and training' is a starting line and sharing

2003-01-01

Since inception in 1986 the National Direction of Nuclear Technology has fulfilled with the assignment known as 'Control of the ionizing radioactivity in its medical and industrial applications'. This strategic task as far as safety, was performed with significant and crucial deficiencies which they even motivated the users to question the reliability of the institution. The deficiencies were mainly as follows: 1) absence of a regulatory frame; 2) insufficient qualification of technical human resources and 3) lack of suitable equipment. From the use for Uruguay of the Model Project and the beginning of a new management of Dinaten (October 2000), a sensible and well-known increase in the quality and efficiency of the regulating function in the country, which we can summarize in the following landmarks: regulatory frame with the use of a basic norm and eight regulating norms according to the main practices that are developed in the country; intensive training of the regulatory body staff; permanent accomplished update of the inventory of sources; beginning of licensing activities; equipment of last generation; regulation of the personal dosimetry services and management of radioactive waste and establishment of a National Program of Radiological Emergencies.

Culture is the basic pattern of shared beliefs, behaviors, and assumptions acquired over time by the people in the organization. Culture is learned and can be modified over time. Many failures in managing change in recent years in the commercial nuclear industry and in the DOE weapons complex can be attributed to not accepting the central axiom of safety, health, and environmental matters. This paper presents specific lessons learned from experiences in commercial nuclear power and US Department of Energy weapons facilities restarts: (1) the attributes of problem plants and symptoms that predict impending regulatory doom; (2) the root causes of plant shutdown by regulators; (3) management infrastructure problems; and (4) actions required by management to effect the culture shift necessary to resume operations

Automated Identification of Core Regulatory Genes in Human Gene Regulatory Networks.

Directory of Open Access Journals (Sweden)

Vipin Narang

Full Text Available Human gene regulatory networks (GRN can be difficult to interpret due to a tangle of edges interconnecting thousands of genes. We constructed a general human GRN from extensive transcription factor and microRNA target data obtained from public databases. In a subnetwork of this GRN that is active during estrogen stimulation of MCF-7 breast cancer cells, we benchmarked automated algorithms for identifying core regulatory genes (transcription factors and microRNAs. Among these algorithms, we identified K-core decomposition, pagerank and betweenness centrality algorithms as the most effective for discovering core regulatory genes in the network evaluated based on previously known roles of these genes in MCF-7 biology as well as in their ability to explain the up or down expression status of up to 70% of the remaining genes. Finally, we validated the use of K-core algorithm for organizing the GRN in an easier to interpret layered hierarchy where more influential regulatory genes percolate towards the inner layers. The integrated human gene and miRNA network and software used in this study are provided as supplementary materials (S1 Data accompanying this manuscript.

Genome-wide identification of regulatory elements and reconstruction of gene regulatory networks of the green alga Chlamydomonas reinhardtii under carbon deprivation.

Directory of Open Access Journals (Sweden)

Flavia Vischi Winck

Full Text Available The unicellular green alga Chlamydomonas reinhardtii is a long-established model organism for studies on photosynthesis and carbon metabolism-related physiology. Under conditions of air-level carbon dioxide concentration [CO2], a carbon concentrating mechanism (CCM is induced to facilitate cellular carbon uptake. CCM increases the availability of carbon dioxide at the site of cellular carbon fixation. To improve our understanding of the transcriptional control of the CCM, we employed FAIRE-seq (formaldehyde-assisted Isolation of Regulatory Elements, followed by deep sequencing to determine nucleosome-depleted chromatin regions of algal cells subjected to carbon deprivation. Our FAIRE data recapitulated the positions of known regulatory elements in the promoter of the periplasmic carbonic anhydrase (Cah1 gene, which is upregulated during CCM induction, and revealed new candidate regulatory elements at a genome-wide scale. In addition, time series expression patterns of 130 transcription factor (TF and transcription regulator (TR genes were obtained for cells cultured under photoautotrophic condition and subjected to a shift from high to low [CO2]. Groups of co-expressed genes were identified and a putative directed gene-regulatory network underlying the CCM was reconstructed from the gene expression data using the recently developed IOTA (inner composition alignment method. Among the candidate regulatory genes, two members of the MYB-related TF family, Lcr1 (Low-CO 2 response regulator 1 and Lcr2 (Low-CO2 response regulator 2, may play an important role in down-regulating the expression of a particular set of TF and TR genes in response to low [CO2]. The results obtained provide new insights into the transcriptional control of the CCM and revealed more than 60 new candidate regulatory genes. Deep sequencing of nucleosome-depleted genomic regions indicated the presence of new, previously unknown regulatory elements in the C. reinhardtii genome

Full Text Available This paper aims to develop a theoretical approach for mapping and determining the effectiveness of green spaces and socio-cultural facilities as providers of urban ecosystem services and urban services in the case of Adana, Turkey. Firstly, green spaces and socio-cultural facilities per capita have been determined and indexed for the neighbourhoods in the city. Then, a distance-based method for estimating the effectiveness of these facilities was used. The distances between the various neighbourhoods and between a given facility and the farthest threshold have been measured and these values have been used to determine the facility effectiveness change value for each neighbourhood. Then, effective values have been calculated and indexed by incorporating the green space and socio-cultural facility values and the effectiveness change values for the neighbourhoods. Finally, point-based effective green spaces and socio-cultural facilities index values have been converted to continuous surface values in a GIS (geographic information system environment in order to utilize as a base map for urban physical planning purposes. According to the outcomes of this study, the distribution of green spaces and socio-cultural facilities of the neighbourhoods are imbalanced and index values of these facilities range in between 45 and 84 out of 100.

Mowle, Elyse N; Georgia, Emily J; Doss, Brian D; Updegraff, John A

The purpose of this paper is to test the utility of regulatory focus theory principles in a real-world setting; specifically, Internet hosted text advertisements. Effect of compatibility of the ad text with the regulatory focus of the consumer was examined. Advertisements were created using Google AdWords. Data were collected for the number of views and clicks each ad received. Effect of regulatory fit was measured using logistic regression. Logistic regression analyses demonstrated that there was a strong main effect for keyword, such that users were almost six times as likely to click on a promotion advertisement as a prevention advertisement, as well as a main effect for compatibility, such that users were twice as likely to click on an advertisement with content that was consistent with their keyword. Finally, there was a strong interaction of these two variables, such that the effect of consistent advertisements was stronger for promotion searches than for prevention searches. The effect of ad compatibility had medium to large effect sizes, suggesting that individuals' state may have more influence on advertising response than do individuals' traits (e.g. personality traits). Measurement of regulatory fit was limited by the constraints of Google AdWords. The results of this study provide a possible framework for ad creation for Internet advertisers. This paper is the first study to demonstrate the utility of regulatory focus theory in online advertising.

Objective: To study the bystander effect and associated mechanism mediated through the irradiated cell culture medium. Methods: Splenic natural killer (NK) cells were obtained from healthy male ICR strain mice. Culture medium irradiated with different doses of 60 Co γ-rays was used for culturing Yac-I lymphoma cells. The degree of injury of the latter by activated NK cells was observed. A part of the culture media were pretreated with 1% DMSO, a scavenger of reactive oxygen species (ROS), in order to investigate the possible mechanism of a radiation-induced bystander response. Results: Severer injury was induced in Yac-I cells cultured in the media pre-irradiated with different doses of γ-rays than that in Yac-I cells cultured in unirradiated medium, as shown by increased sensitivity to murine splenic NK cells (P<0.01). Culturing Yac-I cells in DMSO-pretreated medium considerably reduced the activation of NK cells, especially in 0.25 Gy and 0.5 Gy γ-irradiated media. Therefore, it can be expected that DMSO can partly suppress ROS-induced bystander effect. Conclusion: The irradiated culture medium of Yac-I cells can trigger bystander effect. ROS likely plays an important role in radiation-induced bystander effect that can be partly suppressed by pretreatment with DMSO. (authors)

Great Expectations: The Persistent Effect of Institutions on Culture

This research exploits the event of immigration to establish that institutions have a persistent effect on culture. It is argued that immigrants coming from corrupt countries, tend to overtrust the institutions at the host country. This inflated trust of immigrants is documented as the Great Expectations effect. This result is interesting and intriguing for several reasons. First, it highlights the persistent effect of institutions (at the origin coun- try) on the cultural attitudes of immigr...

In the rat, the fast and slow twitch muscles respectively Extensor digitorum longus (EDL) and Soleus present differential characteristics during regeneration. This suggests that their satellite cells responsible for muscle growth and repair represent distinct cellular populations. We have previously shown that satellite cells dissociated from Soleus and grown in vitro proliferate more readily than those isolated from EDL muscle. Fibroblast growth factors (FGFs) are known as regulators of myoblast proliferation and several studies have revealed a relationship between the response of myoblasts to FGF and the expression of myogenic regulatory factors (MRF) of the MyoD family by myoblasts. Therefore, we presently examined the possibility that the satellite cells isolated from EDL and Soleus muscles differ in the expression of FGF receptors (FGF-R) and of MRF expression. FGF-R1 and -R4 were strongly expressed in proliferating cultures whereas FGF-R2 and R3 were not detected in these cultures. In differentiating cultures, only -R1 was present in EDL satellite cells while FGF-R4 was also still expressed in Soleus cells. Interestingly, the unconventional receptor for FGF called cystein rich FGF receptor (CFR), of yet unknown function, was mainly detected in EDL satellite cell cultures. Soleus and EDL satellite cell cultures also differed in the expression MRFs. These results are consistent with the notion that satellite cells from fast and slow twitch muscles belong to different types of myogenic cells and suggest that satellite cells might play distinct roles in the formation and diversification of fast and slow fibres.

The derivation of hepatocytes from human induced pluripotent stem cells (hiPSC) is of great interest for applications in pharmacological research. However, full maturation of hiPSC-derived hepatocytes has not yet been achieved in vitro. To improve hepatic differentiation, co-cultivation of hiPSC with human umbilical vein endothelial cells (HUVEC) during hepatic differentiation was investigated in this study. In the first step, different culture media variations based on hepatocyte culture medium (HCM) were tested in HUVEC mono-cultures to establish a suitable culture medium for co-culture experiments. Based on the results, two media variants were selected to differentiate hiPSC-derived definitive endodermal (DE) cells into mature hepatocytes with or without HUVEC addition. DE cells differentiated in mono-cultures in the presence of those media variants showed a significant increase ( p < 0.05) in secretion of α-fetoprotein and in activities of cytochrome P450 (CYP) isoenzymes CYP2B6 and CYP3A4 as compared with cells differentiated in unmodified HCM used as control. Co-cultivation with HUVEC did not further improve the differentiation outcome. Thus, it can be concluded that the effect of the used medium outweighed the effect of HUVEC co-culture, emphasizing the importance of the culture medium composition for hiPSC differentiation.

Effects of cyclophosphamide on in vitro human lymphocyte culture and mitogenic stimulation

Cyclophosphamide (CY) has been reported to be inactive in vitro under certain conditions. In the present study, CY was tested for its ability to inhibit human lymphocyte proliferation and to modulate lymphocyte response to mitogens in vitro. The inhibition of or the increase in 3 H-thymidine incorporation in mitogen-stimulated and unstimulated lymphocytes by CY was used as a measure of CY activity in vitro. The results demonstrate that lymphocytes from 10 different persons had a mean decrease of 74% in 3 H-thymidine incorporation in the presence of CY (P less than 0.005). The effect was maximal at a concentration of 160 micrograms/ml. A mean inhibition of 35 and 55% was caused by 10 and 40 micrograms/ml concentrations of CY, respectively. CY also was able to reduce the number of viable cells during 5 days in culture and had a profound effect on mitogen stimulation of lymphocytes. In all cases, CY modulated the stimulation of lymphocytes by phytohemagglutinin (PHA), concanavalin A (Con A), and pokeweed mitogen (PWM) either by augmenting or suppressing the responses. At low concentrations (10 micrograms/ml) it augmented mitogenic stimulation by 46 to 281%. At higher concentrations (20 to 160 micrograms/ml), CY had a suppressive effect with a maximum suppression of 99%. The CY-induced immunomodulation is perhaps caused by its action on the regulatory T cells. When tested in vitro, CY had inhibitory activity on T cells

Previous research has been inconclusive regarding the impact of glucose ingestion and gluco-regulatory control on cognitive performance in healthy older adults. The aim of this research was to determine whether glucose specifically enhanced episodic memory in an older population. In addition, the link between individual differences in glucose regulation and the magnitude of the enhancement effect was examined. A within subjects, counterbalanced, crossover design was used with 20 participants (60-80 year olds), each serving as his/her control. Episodic memory was tested by presenting unrelated paired associates followed by immediate and delayed cued recall, and delayed recognition, under single and dual task conditions. In addition, a battery of cognitive tests was administered, including tests of semantic memory, working memory and speed of processing. Glucose ingestion was found to largely facilitate performance of episodic memory. Furthermore, subsidiary analyses found that gluco-regulatory efficiency predicted episodic memory performance in both control and glucose conditions. A boost in performance after glucose ingestion was particularly seen in the episodic memory domain. Notably, strong evidence was provided for the utility of gluco-regulatory control measures as indicators of cognitive decline in the elderly.

The regulatory control of radioactive sources in Argentina

International Nuclear Information System (INIS)

Rojkind, Roberto Hector

1997-01-01

Argentina has been conducting nuclear activities for more than forty years, and as early as in 1956 established a Regulatory Authority. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations had been set in Argentina, before the accident in Goiania. The conclusions drawn from that accident encouraged in Argentina the improvement of some regulatory procedures and helped to enhance the quality of the regulatory process. Therefore, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain improved. Some lessons learned in Argentina from the accident in Goiania and the main characteristics of an effective enforcement program helpful to prevent radiological accidents in industrial, medical, research and teaching uses of radioactive sources are presented.

enhanced only if meaningful goals and targets are established); - analysis of overall plant performance; - safety culture indicator (qualitative indicator). Some of the indicators, like Sudden outages, unavailability of Safety Systems, Collective Radiation Exposure, Station Effluents, are analysed under Operating Performance parameter of KANUPP Report for the period 1994-1998. As observed from the findings by DNSRP inspectors and corrective actions taken by KANUPP during regulatory inspections and the trend analysis of the safety performance indicators for Workers Radiation Safety it can be concluded that the Regulatory Body in Pakistan is performing its responsibility in an effective manner with the co-operation of the Management of the Utility. It is concluded that the general trend observed during this study is expected from an old plant like KANUPP. The encouraging aspect which matters for the Regulators is the trend observed for the radiation dose internal to external ratio for the period 1994 to 1998. This ratio has started decreasing now after doing some maintenance work. Another important parameter of safety concern is the number of forced outages which have been decreasing from 1994 to 1998. Kanupp is facing operational problems mainly due to its Ageing and some other maintenance activities. These conditions can cause safety concerns that, if not appropriately addressed, would require the licensee to shut down the plant. This deficiency will be rectified to a large extent when the effort to produce a revised full scope PSAR is complete, and a new license issued. (author)

2018-05-01

Full Text Available Background/Aims: This study aimed to explore whether the adoptive transfusion of autologous CD4+CD25+ regulatory T cells (CD4+CD25+ Tregs has a therapeutic effect on Experimental autoimmune neuritis (EAN model rats, and it provides new experimental and theoretical bases for the immunotherapy of Guillain-Barre syndrome (GBS. Methods: CD4+CD25+ Tregs were sorted from the spleens of rats using immunomagnetic bead separation techniques combined with flow cytometry. Their in vitro inhibitory function was determined using a lymphocyte proliferation inhibition test, and their purity was confirmed by flow cytometry. Cells were stimulated using CD3/CD28 monoclonal antibodies and were cultured in culture medium containing interleukin 2 (IL-2, transforming growth factor-β (TGF-β and rapamycin. After 15 days of amplification, CD4+CD25+ Tregs were collected and transfused into EAN model rats. Changes in the pathology and electron microscopical morphology of rat sciatic nerves in the normal group, untreated group, low-dose group (2 × 107 and high-dose group (4 × 107 were observed, and the expression of CD4+CD25+FOXP3 in peripheral blood in the four groups of rats was detected by flow cytometry. Results: Compared with rats in the untreated group, rats in the treatment groups had significantly reduced infiltration of inflammatory cells in the sciatic nerve, as well as myelin and axonal damage. Additionally, the CD4+CD25+ Tregs levels in peripheral blood were significantly higher than those in the untreated group (P< 0. 05. Moreover, the therapeutic effect became more significant with an increase in the dose of adoptive transfusion. Conclusion: Adoptive transfusion of CD4+CD25+ Tregs into EAN model rats has significant therapeutic effects.

Dynamic SPR monitoring of yeast nuclear protein binding to a cis-regulatory element

International Nuclear Information System (INIS)

Mao, Grace; Brody, James P.

2007-01-01

Gene expression is controlled by protein complexes binding to short specific sequences of DNA, called cis-regulatory elements. Expression of most eukaryotic genes is controlled by dozens of these elements. Comprehensive identification and monitoring of these elements is a major goal of genomics. In pursuit of this goal, we are developing a surface plasmon resonance (SPR) based assay to identify and monitor cis-regulatory elements. To test whether we could reliably monitor protein binding to a regulatory element, we immobilized a 16 bp region of Saccharomyces cerevisiae chromosome 5 onto a gold surface. This 16 bp region of DNA is known to bind several proteins and thought to control expression of the gene RNR1, which varies through the cell cycle. We synchronized yeast cell cultures, and then sampled these cultures at a regular interval. These samples were processed to purify nuclear lysate, which was then exposed to the sensor. We found that nuclear protein binds this particular element of DNA at a significantly higher rate (as compared to unsynchronized cells) during G1 phase. Other time points show levels of DNA-nuclear protein binding similar to the unsynchronized control. We also measured the apparent association complex of the binding to be 0.014 s -1 . We conclude that (1) SPR-based assays can monitor DNA-nuclear protein binding and that (2) for this particular cis-regulatory element, maximum DNA-nuclear protein binding occurs during G1 phase

Biological effects of low doses of ionizing radiations. Evidence of effect of pre-irradiation of culture medium on subsequent growth in Cyanobacterium Synechococcus lividus in culture

1986-01-01

In order to distinguish the direct effects of low dose of ionizing radiations at the cellular level from those indirect through the culture medium, we have compared proliferation of Synechococcus lividus grown in pre-irradiated medium to proliferation of cultures grown in non-irradiated medium. A stimulation of growth was observed at the 7th day in cultures inoculated with cells selected in deceleration phase, while an inhibition occured in cultures inoculated with exponential growing cells. Addition of catalase (100 U/ml) counteracted the stimulating effect but did not change the inhibiting effect induced by pre-irradiated medium. Results demonstrated the indirect effect of low dose of irradiation, implying hydrogen peroxide, but let us to think that others radioproduced products could be also involved in the mechanism [fr

Delay-independent stability of genetic regulatory networks.

Wu, Fang-Xiang

2011-11-01

Genetic regulatory networks can be described by nonlinear differential equations with time delays. In this paper, we study both locally and globally delay-independent stability of genetic regulatory networks, taking messenger ribonucleic acid alternative splicing into consideration. Based on nonnegative matrix theory, we first develop necessary and sufficient conditions for locally delay-independent stability of genetic regulatory networks with multiple time delays. Compared to the previous results, these conditions are easy to verify. Then we develop sufficient conditions for global delay-independent stability for genetic regulatory networks. Compared to the previous results, this sufficient condition is less conservative. To illustrate theorems developed in this paper, we analyze delay-independent stability of two genetic regulatory networks: a real-life repressilatory network with three genes and three proteins, and a synthetic gene regulatory network with five genes and seven proteins. The simulation results show that the theorems developed in this paper can effectively determine the delay-independent stability of genetic regulatory networks.

This study examined the effects of message frames when they were culturally tailored. Focusing on one aspect of culture-individualism and collectivism-the study discovered some similar patterns across cultures: The effect of message framing in motivating preventive behaviors could be moderated by the cultural values embedded in the messages. Messages focusing on individualistic gains and collectivistic losses successfully increased people's intention to adopt preventive behaviors. Practical and theoretical implications are discussed.

FORECAST: Regulatory effects cost analysis software manual -- Version 4.1. Revision 1

International Nuclear Information System (INIS)

Lopez, B.; Sciacca, F.W.

1996-07-01

The FORECAST program was developed to facilitate the preparation of the value-impact portion of NRC regulatory analyses. This PC program integrates the major cost and benefit considerations that may result from a proposed regulatory change. FORECAST automates much of the calculations typically needed in a regulatory analysis and thus reduces the time and labor required to perform these analyses. More importantly, its integrated and consistent treatment of the different value-impact considerations should help assure comprehensiveness, uniformity, and accuracy in the preparation of NRC regulatory analyses. The Current FORECAST Version 4.1 has been upgraded from the previous version and now includes an uncertainty package, an automatic cost escalation package, and other improvements. In addition, it now explicitly addresses public health impacts, occupational health impacts, onsite property damage, and government costs. Thus, FORECAST Version 4.1 can treat all attributes normally quantified in a regulatory analysis

Purpose The purpose of this paper is to test the utility of regulatory focus theory principles in a real-world setting; specifically, Internet hosted text advertisements. Effect of compatibility of the ad text with the regulatory focus of the consumer was examined. Design/methodology/approach Advertisements were created using Google AdWords. Data were collected for the number of views and clicks each ad received. Effect of regulatory fit was measured using logistic regression. Findings Logistic regression analyses demonstrated that there was a strong main effect for keyword, such that users were almost six times as likely to click on a promotion advertisement as a prevention advertisement, as well as a main effect for compatibility, such that users were twice as likely to click on an advertisement with content that was consistent with their keyword. Finally, there was a strong interaction of these two variables, such that the effect of consistent advertisements was stronger for promotion searches than for prevention searches. Research limitations/implications The effect of ad compatibility had medium to large effect sizes, suggesting that individuals’ state may have more influence on advertising response than do individuals’ traits (e.g. personality traits).

Integrated Regulatory Review Service (IRRS) Guidelines for the Preparation and Conduct of IRRS Missions

International Nuclear Information System (INIS)

2013-01-01

: International Basic Safety Standards (IAEA Safety Standards Series No. GSR Part 3 - Interim Edition), may be used in conjunction with GSR Part 1 in order to conduct a thorough review of a national legal and governmental infrastructure. The IRRS recognizes that organizational structure and regulatory processes vary from country to country depending on national legal and administrative systems, the size and structure of the nuclear and radiation protection programme, financial resources available to the regulatory body, social customs and cultural traditions. The IRRS process allows for such variations within a single integrated review service. The IRRS process includes performance and prescriptive approaches to varying degrees. It is performance oriented in that it accepts various approaches to the organization and practices of a regulatory framework and body that contribute to a strong national nuclear and radiation safety regime. At the same time the review process is prescriptive in its objective comparison against IAEA standards and guidance. These IRRS guidelines have been published to encourage consistency and comprehensiveness in the preparation for, conduct and follow-up of an IRRS mission. During an IRRS mission, recommendations and suggestions may be offered to the host country. Recommendations made are related to items of direct relevance to safety as referenced in IAEA Safety Requirements, while suggestions made are related to items which are not be essential to compatibility with IAEA standards but may enhance the effectiveness of the national nuclear and radiation safety regime and/or improve the organization or performance of the regulatory body. Good practices identified may be documented for consideration by other States.

We investigated the effect of collagen on magnetization transfer contrast (MTC) in cultured cartilage. In our culture system, only collagen synthesis was increased by the addition of vitamin C, while proteoglycan synthesis and the number of chondrocytes were unaffected. The MTC effect was assessed by using an off-resonance RF pulse (0.3 KHz off-resonance, sinc wave of 18 msec, maximum amplitude 4.61 x 10 -4 T) on a GRASS sequence. The cartilage cultured with vitamin C showed a higher MTC effect than that cultured without vitamin C. The major role of collagen on MTC was confirmed in living cartilage tissue. (author)

For countries initiating or considering to start their nuclear power programs; developing a successful safety culture is of a great challenge, owing to lack of experience and the sensitive nature of the nuclear industry in general. The Jordanian case was chosen since Jordan is in the early stages of its nuclear program and the establishment of an effective safety culture is crucial to guarantee the safe operation of its future nuclear facilities. It also should be noted that Fukushima accident has adversely affected the progress of the Jordanian nuclear program driven by the negative public opinion. The government shifts the policies toward enhancing the nuclear safety by enforcing the communication between the engaged parties and openness and transparency with public. In the wake of Fukushima accident the Jordanian government reassured the appropriate siting criteria and siting review, the leadership and the organizations commitment to nuclear safety by adopting advanced reactor technology, the consideration of modern operator accident mitigation strategies and the increased and close cooperation with IAEA and adherence to evolving international safety standards. The progress in the Jordanian nuclear power project in order to satisfy the IAEA requirements was quantified and ranked. A good progress was shown in some aspects, for example in the multicultural and multi-national elements and the establishment of an independent and effective regulatory body. However, some elements, concerning the understanding of the safety culture, management system of the regulatory body and the cultural assessment was not satisfied and an urgent need to focus on and enhance those aspects are required by the Jordanian government. Some elements, for example the leadership, communication and competence, have partial fulfillment of the IAEA requirements. However enhancing those aspects is required in the short and the mid-term in order to guarantee a well-established nuclear power

The regulatory control of radioactive sources in Argentina

International Nuclear Information System (INIS)

Rojkind, R.H.

1998-01-01

Argentina has been conducting nuclear activities for more than forty years, and had established a Regulatory Authority as early as in 1956. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations were in force in Argentina before the accident in Goiania. The conclusions drawn from the Goiania accident encouraged the Argentine authorities to improve some regulatory procedures and helped to enhance the quality of the regulatory process. As a result, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain have improved. Lessons learned in Argentina from the accident in Goiania are presented as well as the main characteristics of an effective enforcement programme to prevent radiological accidents when radioactive sources are used for industrial, medical, research and teaching purposes.

Safety culture in the maintenance of nuclear power plants

International Nuclear Information System (INIS)

2005-01-01

Safety culture is the complexity of beliefs, shared values and behaviour reflected in making decisions and performing work in a nuclear power plant or nuclear facility. The definition of safety culture and the related concepts presented in the IAEA literature are widely known to experts. Since the publication of Safety Culture, issued by the IAEA as INSAG-4 in 1991, the IAEA has produced a number of publications on strengthening the safety culture in organizations that operate nuclear power plants and nuclear facilities. However, until now the focus has been primarily on the area of operations. Apart from operations, maintenance in plants and nuclear facilities is an aspect that deserves special attention, as maintenance activities can have both a direct and an indirect effect on equipment reliability. Adverse safety effects can arise, depending upon the level of skill of the personnel involved, safety awareness and the complexity of the work process. Any delayed effects resulting from challenges to maintenance can cause interruptions in operation, and hence affect the safety of a plant or facility. Building upon earlier IAEA publications on this topic, this Safety Report reviews how challenges to the maintenance of nuclear power plants can affect safety culture. It also highlights indications of a weakening safety culture. The challenges described are in areas such as maintenance management; human resources management; plant condition assessment and the business environment. The steps that some Member States have taken to address safety culture aspects are detailed and singled out as good practices, with a view to disseminating and exchanging experiences and lessons learned. Although this report is primarily directed at plant maintenance organizations, the subject matter is applicable to a wider audience, including plant contracting organizations and regulatory authorities

Effects of Kisspeptin-10 on Lipid Metabolism in Cultured Chicken Hepatocytes

Directory of Open Access Journals (Sweden)

J. Wu

2012-09-01

Full Text Available Our previous studies showed that kisspeptin-10 (Kp-10 injected in vivo can markedly increase lipid anabolism in liver of quails. In order to investigate the direct effect of Kp-10 on lipid metabolism of hepatocytes in birds, cells were separated from embryos livers and cultured in vitro with 0, 100 and 1,000 nM Kp-10, respectively. The results showed that after 24 h treatment, cells viability was not affected by 100 nM Kp-10, but showed a mild decrease with 1,000 nM Kp-10 compared to the control cells. Based on the results of the cell viability, 100 nM dosage of Kp-10 was selected for the further study and analysis. Compared with control cells, total cholesterol (Tch contents in 100 nM treated cells were increased by 51.23%, but did not reach statistical significance, while the level of triglyceride (TG, high density of lipoprotein-cholesterol (HDL-C and low density of lipoprotein-cholesterol (LDL-C were significantly increased. Real-time PCR results showed that ApoVLDL-II mRNA expression had a tendency to increase, genes including sterol regulatory element-binding protein-1 (SREBP-1, acetyl coenzyme A carboxylase α (ACCα, carnitine palmitoyltransferase 1 (CPT1, 3-hydroxyl-3-methylglutaryl-coenzyme A reductases (HMGCR and stearyl coenzyme A dehydrogenase-1 (SCD1 mRNA in hepatocytes were significantly down-regulated by 100 nM Kp-10. However, contrary to its gene expression, SREBP-1 protein expression was significantly up-regulated by 100 nM Kp-10. Some of the significant correlations in mRNA expression were found between genes encoding hepatic factors or enzymes involved in lipid metabolism in liver of birds. These results indicate that Kp-10 stimulates lipid synthesis directly in primary cultured hepatocytes of chickens.

Approaches to investigate gene functions in experimental biology are becoming more diverse and reliable. Furthermore, several kinds of tissues and organs that possess their original identities can be generated in petri dishes from stem cells including embryonic, adult and induced pluripotent stem cells. Researchers now have several choices of experimental methods and their combinations to analyze gene functions in various biological systems. Here, as an example we describe one of the better protocols, which combines three-dimensional embryonic stem cell culture with small regulatory RNA-mediated technologies, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9), and inducible RNA interference (RNAi). This protocol allows investigation of genes of interest to better understand gene functions in target tissues (or organs) during in vitro development.

A major application area of NMs is drug delivery. Many nanomedicinal products (NMPs currently on the market or in clinical trials are most often based on liposomal products or polymer conjugates. NMPs can be designed to target specific tissues, eg, tumors. In virtually all cases, NMPs will eventually reach the immune system. It has been shown that most NMs end up in organs of the mononuclear phagocytic system, notably liver and spleen. Adverse immune effects, including allergy, hypersensitivity, and immunosuppression, have been reported after NMP administration. Interactions of NMPs with the immune system may therefore constitute important side effects. Currently, no regulatory documents are specifically dedicated to evaluate the immunotoxicity of NMs or NMPs. Their immunotoxicity assessment is performed based on existing guidelines for conventional substances or medicinal products. Due to the unique properties of NMPs when compared with conventional medicinal products, it is uncertain whether the currently prescribed set of tests provides sufficient information for an adequate evaluation of potential immunotoxicity of NMPs. The aim of this study was therefore, to compare the current regulatory immunotoxicity testing requirements with the accumulating knowledge on immunotoxic effects of NMPs in order to identify potential gaps in the safety assessment. This comparison showed that immunotoxic effects, such as complement activation-related pseudoallergy, myelosuppression, inflammasome

indicators, the symptoms and significance of shortcomings and degradation in the safety management processes and safety culture and hence failed to take effective corrective actions at an early stage. Key performance issues such as critical oversight, self assessment processes and effective corrective action programmes were not fully appreciated by senior management even after performance deficiencies were identified by the regulator and other external agencies. The seeming inability of the regulator to influence this senior management level, especially at the early stages of safety performance degradation was a major contributing factor in the continuation of the performance decline to the point that regulatory intervention became a necessity. Recovery processes commonly used a new utility senior management team to kick-start the change process and corresponding regulatory resource increases focused on monitoring the recovery. A comprehensive recovery plan and an interactive relationship with the regulator were deemed essential for a successful recovery. A review of the developing safety culture was a factor considered necessary to ensure sustainability. Public involvement in the regulatory monitoring process helped restore their confidence in the regulator, utility and plant management. The group recommended IAEA continue work to develop guidance for senior corporate management and regulators in this area (author) (ml)

The US domestic uranium industry is at a crossroads. Historic low prices for uranium, combined with stringent and often irrational regulatory requirements, pose a very real threat to the industry's continued viability. The Nuclear Regulatory Commission has taken a number of innovative steps to reform and rationalize its regulatory program. However, if the domestic uranium recovery industry is to remain viable, additional steps toward innovation and reform are needed, and effective implementation of reforms adopted by the Commission is essential.

Regulatory control, nuclear safety regulation and waste management in Spain

International Nuclear Information System (INIS)

Martin, A.

2000-01-01

This article presents the challenges that faces the spanish regulatory authority. The deregulation of electricity industry imposes severe changes in nuclear power economics and forces nuclear power to compete with other sources of electricity. A pressure is perceived for regulatory effectiveness primarily since the cost of regulation is a component of the cost of the product. This effectiveness gain in regulatory control will be reached through systematic strategic analysis, formulation and implementation. The regulatory aspects of plant life extension and of waste management are examined

Ethics and Regulatory Challenges and Opportunities in Patient-Centered Comparative Effectiveness Research.

Sugarman, Jeremy

2016-04-01

The Affordable Care Act includes provisions for the conduct of large-scale, patient-centered comparative effectiveness research. Such efforts aim toward the laudable moral goal of having evidence to improve health care decision making. Nevertheless, these pragmatic clinical research efforts that typically pose minimal incremental risk and are enmeshed in routine care settings perhaps surprisingly encounter an array of ethics and regulatory challenges and opportunities for academic health centers. An emphasis on patient-centeredness forces an examination of the appropriateness of traditional methods used to protect the rights, interests, and welfare of participants. At the same time, meaningful collaboration with patients throughout the research process also necessitates ensuring that novel approaches to research (including recruitment and consent) entail necessary protections regarding such issues as privacy. As the scientific and logistical aspects of this research are being developed, substantial attention is being focused on the accompanying ethics and regulatory issues that have emerged, which should help to facilitate ethically appropriate research in a variety of contexts.

2011-01-01

Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

This article summarizes the definitions, means, and research of adapting psychotherapy to clients' cultural backgrounds. We begin by reviewing the prevailing definitions of cultural adaptation and providing a clinical example. We present an original meta-analysis of 65 experimental and quasi-experimental studies involving 8,620 participants. The omnibus effect size of d = .46 indicates that treatments specifically adapted for clients of color were moderately more effective with that clientele than traditional treatments. The most effective treatments tended to be those with greater numbers of cultural adaptations. Mental health services targeted to a specific cultural group were several times more effective than those provided to clients from a variety of cultural backgrounds. We recommend a series of research-supported therapeutic practices that account for clients' culture, with culture-specific treatments being more effective than generally culture-sensitive treatments. © 2010 Wiley Periodicals, Inc.

Depigmented-polymerised allergoids favour regulatory over effector T cells: enhancement by 1α, 25-dihydroxyvitamin D3.

Allergen immunotherapy (SIT) is the only treatment for allergic disease capable of modifying disease long term. To reduce the risk of anaphylaxis from SIT, allergen-extracts have been modified by polymerisation with glutaraldehyde to reduce IgE binding. It is suggested that these allergoid extracts also have reduced T cell activity, which could compromise clinical efficacy. Effective SIT is thought to act through regulatory T cells (Tregs) rather than activation of effector T cells. There is no published data on the activity of modified extracts on Tregs. We compared the capacity of modified (depigmented-polymerised) versus unmodified (native) allergen extracts of grass pollen and house dust mite to stimulate proliferation/cytokine production and to modulate Treg/effector T cell frequency in cultures of peripheral blood mononuclear cells (PBMC), from volunteers sensitised to both allergens in vitro. Depigmented-polymerised allergen extracts stimulated less proliferation of PBMC, and reduced effector cell numbers after 7 days in culture than did native extracts. However, the frequency of Foxp3+ Tregs in cultures were similar to those seen with native extract so that ratios of regulatory to effector T cells were significantly increased in cultures stimulated with depigmented-polymerised extracts. Addition of 1α, 25-dihydroxyvitamin D3 further favoured Treg, and reduced effector cytokine production, but not interleukin-10. Depigmented-polymerised allergen extracts appear to favour Treg expansion over activation of effector T cells and this may relate to their demonstrated efficacy and safety in SIT. 1α, 25-dihydroxyvitamin D3 further reduces effector T cell activation by allergen extracts and may be a useful adjuvant for SIT.

Purpose The purpose of this paper is to investigate the relationship between patient safety culture and two attitudinal constructs: affective organizational commitment and structural empowerment. In doing so, the main and interaction effects of the two constructs on the perception of patient safety culture were assessed using a cohort of physicians. Design/methodology/approach Affective commitment was measured with the Organizational Commitment Questionnaire, whereas structural empowerment was assessed with the Conditions of Work Effectiveness Questionnaire-II. The abbreviated versions of these surveys were administered to a cohort of 71 post-doctoral medical residents. For the data analysis, hierarchical regression analyses were performed for the main and interaction effects of affective commitment and structural empowerment on the perception of patient safety culture. Findings A total of 63 surveys were analyzed. The results revealed that both affective commitment and structural empowerment were positively related to patient safety culture. A potential interaction effect of the two attitudinal constructs on patient safety culture was tested but no such effect was detected. Research limitations/implications This study suggests that there are potential benefits of promoting affective commitment and structural empowerment for patient safety culture in health care organizations. By identifying the positive associations between the two constructs and patient safety culture, this study provides additional empirical support for Kanter's theoretical tenet that structural and organizational support together helps to shape the perceptions of patient safety culture. Originality/value Despite the wide recognition of employee empowerment and commitment in organizational research, there has still been a paucity of empirical studies specifically assessing their effects on patient safety culture in health care organizations. To the authors' knowledge, this study is the first

Communication planning by the nuclear regulatory body

International Nuclear Information System (INIS)

2002-01-01

The national regulatory body, whose primary mission is to exercise regulatory control over nuclear facilities and the use of radiation sources, but not to promote their use, may be the most credible source of neutral, balanced and accurate information about issues relating to nuclear and radiation safety. It is therefore important for a regulatory body to establish and exercise an effective communication programme to acquaint the public with its oversight functions, capabilities and effectiveness. If the regulatory body is to maintain credibility and to deal promptly and effectively with nuclear or radiological accidents and any other events that may give rise to significant public concerns, and is to communicate clearly and effectively with the public, it must have adequate resources, including experts in nuclear safety. And if maintaining public confidence in the authorities and avoiding unnecessary concerns are among its principal objectives, it must be able to communicate understandably and truthfully about the known extent of any accident, the actions taken in response to it and its implications. In the past, psychological effects as a result of certain severe nuclear and radiological accidents have been compounded by a lack of candour with the public on the part of the authorities and an absence of an appropriate programme of public information. This publication describes good practices and gives practical examples of how the regulatory body can establish a systematic and structured programme for enhancing effective communication with various parties and under various circumstances. The report presupposes an adequate national infrastructure, including an independent regulatory body with sufficient authority and resources to discharge its responsibilities for the regulation of safety. This Safety Report covers the elements of a regulatory body's programme for communication with various audiences and under the different circumstances that may be encountered

Safety culture has been recognized as important to achieve high level of nuclear safety, as several recent events that have occurred in advanced countries were found to have important implications for safety culture. Under the recognition, implementation-focused and practical methods to foster safety culture have become necessary. Development of safety culture indicators for assessing the level of safety culture and identifying some deficiencies is being conducted. This paper examines the regulatory positions of major nuclear power countries on licensee's safety culture, introduces the development status of Korean Safety Culture Indicators and presents its future direction

Regulatory T cell effects in antitumor laser immunotherapy: a mathematical model and analysis

Science.gov (United States)

Dawkins, Bryan A.; Laverty, Sean M.

2016-03-01

Regulatory T cells (Tregs) have tremendous influence on treatment outcomes in patients receiving immunotherapy for cancerous tumors. We present a mathematical model incorporating the primary cellular and molecular components of antitumor laser immunotherapy. We explicitly model developmental classes of dendritic cells (DCs), cytotoxic T cells (CTLs), primary and metastatic tumor cells, and tumor antigen. Regulatory T cells have been shown to kill antigen presenting cells, to influence dendritic cell maturation and migration, to kill activated killer CTLs in the tumor microenvironment, and to influence CTL proliferation. Since Tregs affect explicitly modeled cells, but we do not explicitly model dynamics of Treg themselves, we use model parameters to analyze effects of Treg immunosuppressive activity. We will outline a systematic method for assigning clinical outcomes to model simulations and use this condition to associate simulated patient treatment outcome with Treg activity.

Communication regulatory science is an emerging field that uses validated techniques, tools, and models to inform regulatory actions that promote optimal communication outcomes and benefit the public. In the opening article to this special issue on communication and tobacco regulatory science, we 1) describe Food and Drug Administration (FDA) regulation of tobacco products in the US; 2) introduce communication regulatory science and provide examples in the tobacco regulatory science realm; and 3) describe the special issue process and final set of articles. Communication research on tobacco regulatory science is a burgeoning area of inquiry, and this work advances communication science, informs and potentially guides the FDA, and may help to withstand legal challenges brought by the tobacco industry. This research has the potential to have a major impact on the tobacco epidemic and population health by helping implement the most effective communications to prevent tobacco initiation and increase cessation. This special issue provides an example of 10 studies that exemplify tobacco regulatory science and demonstrate how the health communication field can affect regulation and benefit public health.

Assessment by peer review of the effectiveness of a regulatory programme for radiation safety. Interim report for comment

International Nuclear Information System (INIS)

2002-06-01

This document covers assessment of those aspects of a radiation protection and safety infrastructure that are implemented by the Regulatory Authority for radiation sources and practices using such sources and necessarily includes those ancillary technical services, such as dosimetry services, which directly affect the ability of the Regulatory Authority to discharge its responsibilities. The focus of the guidance in this TECDOC is on assessment of a regulatory programme intended to implement the BSS. The BSS address transportation and waste safety mainly by reference to other IAEA documents. When conducting an assessment, the Review Team members should be aware of the latest IAEA documents (or similar national documents) concerning transportation and waste safety and, if appropriate, nuclear safety, and take them into account to the extent applicable when assessing the effectiveness of the regulatory programme governing radiation protection and safety of radiation source practices in a particular State

Full Text Available Writing, one of the four skills which has to be taught by educators in language learning. Starting from classroom observation implied that students confronted the difficulties in writing involving generating ideas, organizing words, and making compositions. This study supposes to explore some effects of pop culture as authentic materials for English language teaching in improving students‘ writing skill. Due to pop culture relates to students‘ life and experience, it is considered to be a stimulus for gaining students‘ ideas, information, motivation, and interest in teaching writing. The students of secondary school were involved in this study and descriptive case study was employed to observe the importance of pop culture in writing class. Also, questionnaires and students‘ works are the instruments to measure its effects. Both students‘ works and result of the questionnaires pointed out that significantly improvement obtained after applying pop culture. In line with findings, it can be said that pop cultures have significant effects toward students‘ writing skill. So, educators need to apply pop culture as their choices in future planning lesson.

Safety culture in the nuclear field

International Nuclear Information System (INIS)

2005-09-01

The council of IAEA governors ratified twelve elemental principles of physical protection of nuclear matters and installations. These principles will be included in the future updating of the international convention on the physical protection. The F basic principle proposes a definition of the safety culture and recommends that its implementation and its perenniality to be a reality in the concerned organisms.It appears as necessary to precise the concept of safety culture. The twelve principles are as follow: A State liability, B liability during international transports, C legislative and regulatory framework, D competent authority, E operators liability, F safety culture, G threats, H graduated approach, I deep defence, J assurance of the quality, K emergency plan, L confidentiality. The present document is complementary of INSAG-4, 1991 (safety series number 75, INSAG-4 safety culture, a report by the international nuclear safety advisory group, IAEA, 1991) that presents a concept of safety culture. It proposes also, in a particular chapter, the comparisons( common points and specificities) between safety culture and security culture. (N.C.)

Quality assurance within regulatory bodies

International Nuclear Information System (INIS)

1999-06-01

The IAEA directed extensive efforts during the years 1991 to 1995 to the integral revision of all NUSS quality assurance publications, which were approved and issued as Safety Series No.50-C/SG-Q, Quality Assurance for Safety in Nuclear Power Plants and other Nuclear Installations (1996). When these quality assurance publications were developed, their prime focus was on requirements against which work performed by the licensees could be measured and assessed by the regulatory bodies. In this way, they only helped to facilitate the functions of regulators. No requirements or recommendations were provided on how the regulators should ensure the effective implementation of their own activities. The present publication is a first attempt to collect, integrate and offer available experience to directly support performance of regulatory activities. It presents a comprehensive compilation on the application of quality assurance principles and methods by regulatory bodies to their activities. The aim is consistent good performance of regulatory activities through a systematic approach

The effect of regulatory mode on procrastination: Bi-stable parahippocampus connectivity with dorsal anterior cingulate and anterior prefrontal cortex.

Science.gov (United States)

Zhang, Chenyan; Ni, Yan; Feng, Tingyong

2017-06-30

Previous research has elucidated that procrastination can be influenced by regulatory mode orientations. However, the neural mechanism of regulatory modes affecting procrastination is not well understood. To address this question, we employed resting-state functional magnetic resonance imaging (RS-fMRI) to test the influence of two regulatory modes (assessment and locomotion) on procrastination. The behavioral results showed that procrastination was positively correlated with assessment orientation but negatively correlated with locomotion orientation. Neuroimaging results indicated that the functional connectivity between parahippocampal cortex (PHC) and dorsal anterior cingulate (dACC) was negatively correlated with assessment scores, while the functional connectivity between anterior prefrontal cortex (aPFC) and parahippocampal cortex (PHC) was negatively correlated with locomotion scores. Critically, mediation analysis showed that the different effects of two distinct regulatory modes on procrastination were mediated by PHC-dACC and aPFC-PHC functional connectivity respectively. These results suggested that people's procrastination could be predicted by regulatory mode orientations, which is mediated by PHC connectivity with dACC and aPFC respectively. The present study extends our knowledge on procrastination and provides neural mechanism for understanding the link between regulatory mode orientations and procrastination. Copyright © 2017.

Effects of viscoelastic ophthalmic solutions on cell cultures

Directory of Open Access Journals (Sweden)

Madhavan Hajib

1998-01-01

Full Text Available The development of mild but significant inflammation probably attributable to viscoelastic ophthalmic solutions in cataract surgery was recently brought to the notice of the authors, and hence a study of the effects of these solutions available in India, on cell cultures was undertaken. We studied the effects of 6 viscoelastic ophthalmic solutions (2 sodium hyaluronate designated as A and B, and 4 hydroxypropylmethylcellulose designated as C, D, E and F on HeLa, Vero and BHK-21 cell lines in tissue culture microtitre plates using undiluted, 1:10 and 1:100 dilutions of the solutions, and in cover slip cultures using undiluted solutions. Phase contrast microscopic examination of the solutions was also done to determine the presence of floating particles. The products D and F produced cytotoxic changes in HeLa cell line and these products also showed the presence of floating particles under phase contrast microscopy. Other products did not have any adverse effects on the cell lines nor did they show floating particles. The viscoelastic ophthalmic pharmaceutical products designated D and F have cytotoxic effects on HeLa cell line which appears to be a useful cell line for testing these products for their toxicity. The presence of particulate materials in products D and F indicates that the methods used for purification of the solution are not effective.

An international comparison of regulatory organizations and licensing procedures for new nuclear power plants

International Nuclear Information System (INIS)

Bredimas, Alexandre; Nuttall, William J.

2008-01-01

This paper considers measures needed to license new nuclear power plants efficiently. We base our analysis on international standards and a comparison of the national regulatory and licensing framework in seven countries (Canada, France, Germany, Japan, Switzerland, the UK and the USA). We split the review into the organization of regulatory responsibilities and the licensing process. We propose a set of considerations that should be incorporated into national solutions. While conscious of the different cultural fundamentals of each region, we hope this paper will help fuel an emerging debate on this highly topical issue

Understanding the Effects of Users' Behaviors on Effectiveness of Different Exogenous Regulatory Common Pool Resource Management Institutions

Science.gov (United States)

Madani, K.; Dinar, A.

2013-12-01

Tragedy of the commons is generally recognized as one of the possible destinies for common pool resources (CPRs). To avoid the tragedy of the commons and prolonging the life of CPRs, users may show different behavioral characteristics and use different rationales for CPR planning and management. Furthermore, regulators may adopt different strategies for sustainable management of CPRs. The effectiveness of different regulatory exogenous management institutions cannot be evaluated through conventional CPR models since they assume that either users base their behavior on individual rationality and adopt a selfish behavior (Nash behavior), or that the users seek the system's optimal solution without giving priority to their own interests. Therefore, conventional models fail to reliably predict the outcome of CPR problems in which parties may have a range of behavioral characteristics, putting them somewhere in between the two types of behaviors traditionally considered. This work examines the effectiveness of different regulatory exogenous CPR management institutions through a user-based model (as opposed to a system-based model). The new modeling framework allows for consideration of sensitivity of the results to different behavioral characteristics of interacting CPR users. The suggested modeling approach is applied to a benchmark groundwater management problem. Results indicate that some well-known exogenous management institutions (e.g. taxing) are ineffective in sustainable management of CPRs in most cases. Bankruptcy-based management can be helpful, but determination of the fair level of cutbacks remains challenging under this type of institution. Furthermore, some bankruptcy rules such as the Constrained Equal Award (CEA) method are more beneficial to wealthier users, failing to establish social justice. Quota-based and CPR status-based management perform as the most promising and robust regulatory exogenous institutions in prolonging the CPR's life and

Regulatory and licensee surveys

International Nuclear Information System (INIS)

2009-01-01

Prior to the workshop two CSNI/WGHOF surveys were distributed. One survey was directed at regulatory bodies and the other was directed at plant licensees. The surveys were: 1 - Regulatory Expectations of Licensees' Arrangements to Ensure Suitable Organisational Structure, Resources and Competencies to Manage Safety (sent to WGHOF regulatory members). The survey requested that the respondents provide a brief overview of the situation related to plant organisations in their country, their regulatory expectations and their formal requirements. The survey addressed three subjects: the demonstration and documentation of organisational structures, resources and competencies, organisational changes, issues for improvement (for both current and new plants). Responses were received from eleven regulatory bodies. 2 - Approaches to Justify Organisational Suitability (sent to selected licensees). The purpose of the survey to was to gain an understanding of how licensees ensure organisational suitability, resources and competencies. This information was used to assist in the development of the issues and subjects that were addressed at the group discussion sessions. Responses were received from over fifteen licensees from nine countries. The survey requested that the licensees provide information on how they ensure effective organisational structures at their plants. The survey grouped the questions into the following four categories: organisational safety functions, resource and competence, decision-making and communication, good examples and improvement needs. The findings from these surveys were used in conjunction with other factors to identify the key issues for the workshop discussion sessions. The responses from these two surveys are discussed briefly in Sections 4 and 5 of this report. More extensive reviews of the regulatory and licensee responses are provided in Appendix 1

Matadial, B.; Pauls, K.P.

1989-01-01

The effect of chilling on cell growth, cell viability, protein content and protein composition in suspension cultures of L. esculentum and L. hirsutum was investigated. Cell growth for both species was arrested at 2 degrees C but when cultures were transferred to 25 degree C cell growth resumed. There was no difference in viability between control and chilled cultures of L. esculentum, however, L. hirsutum control cultures exhibited larger amounts of Fluorescein Diacetate induced fluorescence than chilled cultures. 35 S-methionine incorporation into proteins was 2.5-2 times higher in L. hirsutum than in L. esculentum. Quantitative and qualitative differences, in 35 S-methionine labelled proteins, between chilled and control cultures were observed by SDS-PAGE and fluorography. Protein content in chilled cultures decreased over time but then increased when cultures were transferred to 25 degrees C

UK professional bodies have established a number of sectorial working parties to provide guidance on the improvement of radiation safety (RS) culture in the workplace. The medical sector provides unique challenges in this regard, and the remit of the medical group was to review the current state of RS culture and to develop a framework for improvement. The review of current RS culture was based on measurable indicators, including data from regulatory inspections, personal monitoring data and incident data. An online survey to capture the RS-related views and experience of hospital staff at all levels was carried out, and the responses provided a wealth of information on RS awareness and implementation across the country. The framework for improving RS culture includes both 'top-down' initiatives to engage management and regulators, and 'bottom-up' initiatives relating to engagement and training of different staff groups. A 'Ten-point Assessment' on what constitutes a good approach to medical RS culture has been proposed, which provides a tool for management to assess RS culture in the workplace and has potential use in regulatory inspections in the UK.

The donor countries need to make decisions on various steps such as whether to fully accept newcomers’ requests, the depth of support, and how the supportive action will be carried out. Such is not an easy task due to limited time, resources, manpower, etc. Thus, creating an infrastructure to support emerging nuclear energy countries is needed. This paper suggests the resource portfolio concept used in business management and aims to analyze the validity of supporting the new entrants’ development of regulatory infrastructure as a case study. This study tries to develop a very simple Excel-based tool for assessing the supporting strategy quantitatively and screening the activities that is projected to be less effective and attractive. There are many countries, so called newcomers, which have expressed interests in developing their own nuclear power program. It has been recognized by the international community that every country considering embarking upon their own nuclear power program should establish their nuclear safety infrastructure to sustain a high level of nuclear safety. The newcomers have requested for considerable assistance from the IAEA and they already have bilateral cooperation programs with the advanced countries with matured nuclear regulatory programs. Currently, the regulatory bodies that provide support are confronted with two responsibilities as follows; the primary objective of the regulatory bodies is to ensure that the operator fulfills the responsibility to protect human health.

Strengthening Regulatory Competence in Pakistan

International Nuclear Information System (INIS)

Sadiq, M.

2016-01-01

Capacity building of Pakistan Nuclear Regulatory Authority is considered an essential element in pursuit of its vision to become a world class regulatory body. Since its inception in 2001, PNRA has continuously endeavoured to invest in its people, develop training infrastructure and impart sound knowledge and professional skills with the aim to improve its regulatory effectiveness. The use of nuclear and radioactive material in Pakistan has increased manifold in recent years, thus induction of more manpower was needed for regulatory oversight. PNRA adopted two pronged approach for meeting the manpower demand (a) employment of university graduates through fast track recruitment drive and (b) induction of graduates by offering fellowships for Master degree programs. Although, the newly employed staff was selected on the basis of their excellent academic qualifications in basic and applied sciences, but they required rigorous knowledge and skills in regulatory perspectives. In order to implement a structured training program, PNRA conducted Training Needs Assessment (TNA) and identified competency gaps of the regulatory staff in legal, technical, regulatory practice and behavioural domains. PNRA took several initiatives for capacity building which included establishment of a training centre for sustainability of trainings, initiation of a fellowship scheme for Master program, attachment of staff at local institutes for on-the-job training and placement at foreign regulatory bodies and organizations for technical development with the assistance of IAEA. The above strategies have been very beneficial in competence building of the PNRA staff to perform all regulatory activities indigenously for nuclear power plants, research reactors and radiation facilities. Provision of vibrant technical support to IAEA and Member States in various programs by PNRA is a landmark of these competence development efforts. This paper summarizes PNRA initiatives and the International Atomic

Increasing evidence suggests that inflammatory processes in the central nervous system that are mediated by microglial activation play a key role in neurodegeneration. Fisetin, a plant flavonol commonly found in fruits and vegetables, is frequently added to nutritional supplements due to its antioxidant properties. In the present study, treatment with fisetin inhibited microglial cell migration and ROS (reactive oxygen species) production. Treatment with fisetin also effectively inhibited LPS plus IFN-γ-induced nitric oxide (NO) production, and inducible nitric oxide synthase (iNOS) expression in microglial cells. Furthermore, fisetin also reduced expressions of iNOS and NO by stimulation of peptidoglycan, the major component of the Gram-positive bacterium cell wall. Fisetin also inhibited the enhancement of LPS/IFN-γ- or peptidoglycan-induced inflammatory mediator IL (interlukin)-1 β expression. Besides the antioxidative and anti-inflammatory effects of fisetin, our study also elucidates the manner in fisetin-induced an endogenous anti-oxidative enzyme HO (heme oxygenase)-1 expression. Moreover, the regulatory molecular mechanism of fisetin-induced HO-1 expression operates through the PI-3 kinase/AKT and p38 signaling pathways in microglia. Notably, fisetin also significantly attenuated inflammation-related microglial activation and coordination deficit in mice in vivo.

Full Text Available Increasing evidence suggests that inflammatory processes in the central nervous system that are mediated by microglial activation play a key role in neurodegeneration. Fisetin, a plant flavonol commonly found in fruits and vegetables, is frequently added to nutritional supplements due to its antioxidant properties. In the present study, treatment with fisetin inhibited microglial cell migration and ROS (reactive oxygen species production. Treatment with fisetin also effectively inhibited LPS plus IFN-γ-induced nitric oxide (NO production, and inducible nitric oxide synthase (iNOS expression in microglial cells. Furthermore, fisetin also reduced expressions of iNOS and NO by stimulation of peptidoglycan, the major component of the Gram-positive bacterium cell wall. Fisetin also inhibited the enhancement of LPS/IFN-γ- or peptidoglycan-induced inflammatory mediator IL (interlukin-1 β expression. Besides the antioxidative and anti-inflammatory effects of fisetin, our study also elucidates the manner in fisetin-induced an endogenous anti-oxidative enzyme HO (heme oxygenase-1 expression. Moreover, the regulatory molecular mechanism of fisetin-induced HO-1 expression operates through the PI-3 kinase/AKT and p38 signaling pathways in microglia. Notably, fisetin also significantly attenuated inflammation-related microglial activation and coordination deficit in mice in vivo. These findings suggest that fisetin may be a candidate agent for the development of therapies for inflammation-related neurodegenerative diseases.

Galectin-1 (Gal-1) is required for the development of B cells in the bone marrow (BM), however very little is known about the contribution of Gal-1 to the development of B cell regulatory function. Here, we report an important role for Gal-1 in the induction of B cells regulatory function. Mice deficient of Gal-1 (Gal-1 -/- ) showed significant loss of Transitional-2 (T2) B cells, previously reported to include IL-10 + regulatory B cells. Gal-1 -/- B cells stimulated in vitro via CD40 molecules have impaired IL-10 and Tim-1 expression, the latter reported to be required for IL-10 production in regulatory B cells, and increased TNF-α expression compared to wild type (WT) B cells. Unlike their WT counterparts, T2 and T1 Gal-1 -/- B cells did not suppress TNF-α expression by CD4 + T cells activated in vitro with allogenic DCs (allo-DCs), nor were they suppressive in vivo, being unable to delay MHC-class I mismatched skin allograft rejection following adoptive transfer. Moreover, T cells stimulated with allo-DCs show an increase in their survival when co-cultured with Gal-1 -/- T2 and MZ B cells compared to WT T2 and MZ B cells. Collectively, these data suggest that Gal-1 contributes to the induction of B cells regulatory function.

ASCOT guidelines revised 1996 edition. Guidelines for organizational self-assessment of safety culture and for reviews by the assessment of safety culture in organizations team

International Nuclear Information System (INIS)

1996-01-01

In order to properly assess safety culture, it is necessary to consider the contribution of all organizations which have an impact on it. Therefore, while assessing the safety culture in an operating organization it is necessary to address at least its interfaces with the local regulatory agency, utility corporate headquarters and supporting organizations. These guidelines are primarily intended for use by any organization wishing to conduct a self-assessment of safety culture. They should also serve as a basis for conducting an international peer review of the organization's self-assessment carried out by an ASCOT (Assessment of Safety Culture in Organizations Team) mission

Industry Presentation to Regulatory Workshop

Treasure, Mark

2012-01-01

Mr. Mark Treasure from EDF NGL gave a presentation on industry perspectives on safety culture oversight. Mr. Treasure is the Nuclear Inspection and Oversight Manager within the Safety and Regulation Division. The presentation started with an explanation of the role of the nuclear inspection and oversight group (internal regulator), and their current approach to internal oversight of safety culture. A key element of the current internal regulatory oversight program is Management and Leadership Assessments. These are carried out by a team including management peers from other plants to enhance credibility. Findings can be linked to safety performance, and typically identify issues in areas such as accountability arrangements and strategic focus of the leadership team. Safety indicators have also been introduced to show trends in safety management and safety performance for each EDF UK nuclear power plant. A periodic nuclear safety culture survey is also carried out to identify focus areas and progress. The presentation included discussion on views of the role of the nuclear regulator. Important aspects were identified as: - Supporting the internal regulator by seeking to understand before taking enforcement action, maintaining an open dialogue and recognising that this area is complex and that there is rarely a 'silver bullet' solution. - Communication: being visible and actively discussing safety improvement, and use of language which emphasises nuclear safety rather than legal compliance. - Positive reinforcement to recognise efforts and encourage further improvement

Organizational health culture is a health-oriented core characteristic of the organization that is shared by all members. It is effective in regulating health-related behavior for employees and could therefore influence the effectiveness of health promotion efforts among organizations and employees. This study applied a multilevel analysis to verify the effects of organizational health culture on the organizational and individual effectiveness of health promotion. At the organizational level, we investigated the effect of organizational health culture on the organizational effectiveness of health promotion. At the individual level, we adopted a cross-level analysis to determine if organizational health culture affects employee effectiveness through the mediating effect of employee health behavior. The study setting consisted of the workplaces of various enterprises. We selected 54 enterprises in Taiwan and surveyed 20 full-time employees from each organization, for a total sample of 1011 employees. We developed the Organizational Health Culture Scale to measure employee perceptions and aggregated the individual data to formulate organization-level data. Organizational effectiveness of health promotion included four dimensions: planning effectiveness, production, outcome, and quality, which were measured by scale or objective indicators. The Health Promotion Lifestyle Scale was adopted for the measurement of health behavior. Employee effectiveness was measured subjectively in three dimensions: self-evaluated performance, altruism, and happiness. Following the calculation of descriptive statistics, hierarchical linear modeling (HLM) was used to test the multilevel hypotheses. Organizational health culture had a significant effect on the planning effectiveness (β = .356, p production (β = .359, p promotion. In addition, results of cross-level moderating effect analysis by HLM demonstrated that the effects of organizational health culture on three dimensions of

Radiobiological effects of gamma radiation on different types of rice before or during in vitro culture, combined treatments of 137 Cs γ-rays and NaN 3 on mature embryo culture, and irradiation on growth of calli derived from anther in rice were studied. The dose-effects relations of callus induction rate and callus growth rate could be fitted according to the multi-target and single-hit model. Effect of somatic cultures of different types in rice was different. Increase in plant regeneration capacity was found with 100, 150 Gy gamma rays. Decrease of callus induction rate, callus growth rate and callus differentiation rate (especially in the 1st culture) were observed in combined treatments of γ-rays and NaN 3 . However, mutagenic effects of treatments with γ-rays were much higher than those of combined treatment of γ-rays and NaN 3 in the 2nd and the 3rd culture. Combined treatments of 137 Cs γ-rays with 200 Gy and 2 mmol NaN 3 were suitable for explant in rice before culture. To irradiate the calli derived from anther in rice with 30 Gy gamma rays can rise plant regeneration capacity during continuing culture

Does the type of media used to culture embryos for IVF influence the birthweight and length of neonates? No significant differences were observed in birthweight and length among the three embryo culture media used for in vitro embryo culture. Since the establishment of IVF as an assisted reproductive technology (ART), many different culture systems have been used for the development of human embryos. Some studies have shown that the types of culture media influence the newborn birthweight; however, other studies have shown no effect. To further explore this contradictory issue, we compared the birthweight and length of neonates born after the transfer of embryos cultured in one of three commercially available media. This retrospective analysis of birthweight and length of newborns included 1201 women who delivered singletons and 445 women who delivered twins. The following three commercially available culture media were used: G5™, Global and Quinn's advantage media. Women who underwent IVF-ET cycles between 2008 and 2010 were analyzed. Patients younger than 40 years of age with a body mass index (BMI) culture medium. Inter-twin mean birthweight and length disparities were analyzed, but were not shown to be significantly different. Multiple linear regression analysis showed that maternal weight, maternal height, gestational age and infant gender were significantly related to birthweight, and paternal height, gestational age and newborn complications were significantly associated with birth length. The current study showed that birthweight and length of newborns were not associated with the embryo culture medium. More research needs to be performed to analyze the effects of other culture medium formulations and to evaluate the long-term effects of embryo culture medium on the health of children conceived through ART. WIDER IMPLICATIONS OF THESE FINDINGS: Our retrospective study suggests that embryo culture medium does not influence neonatal birthweight and length

Platelet concentrate lysates (PCLs) are increasingly used in regenerative medicine. We have developed a solvent/detergent (S/D)-treated PCL. The functional properties of this preparation should be unveiled. We hypothesized that, due to transforming growth factor-β1 (TGF-β1) content, PCLs may exert immunosuppressive and anti-inflammatory functions. PCL was prepared by S/D treatment, oil extraction, and hydrophobic interaction chromatography. The content of TGF-β in PCL was determined by enzyme-linked immunosorbent assay. Cultured CD4+ T cells were used to investigate the effects of PCL on expression of transcription factor forkhead box P3 (Foxp3), the inhibition of T-cell proliferation, and cytokine production. The regulatory function of PCL-converted CD4+ T cells was analyzed by suppressive assay. The BALB/c mice were given PCL-converted CD4+ T cells before ovalbumin (OVA) sensitization and challenge using an asthma model. Inflammatory parameters, such as the level of immunoglobulin E (IgE), airway hyperresponsiveness (AHR), bronchial lavage fluid eosinophils, and cytokines were assayed. Recombinant human (rHu) TGF-β1 was used as control. PCL significantly enhanced the development of CD4+Foxp3+-induced regulatory T cells (iTregs). Converted iTregs produced neither Th1 nor Th2 cytokines and inhibited normal T-cell proliferation. PCL- and rHuTGF-β-converted CD4+ T cells prevented OVA-induced asthma. PCL- and rHuTGF-β-modified T cells both significantly reduced expression levels of OVA-specific IgE and significantly inhibited the development of AHR, airway eosinophilia, and Th2 responses in mice. S/D-treated PCL promotes Foxp3+ iTregs and exerts immunosuppressive and anti-inflammatory properties. This finding may help to understand the clinical properties of platelet lysates. © 2013 American Association of Blood Banks.

The Decade of Vaccines Collaboration and development of the Global Vaccine Action Plan provides a catalyst and unique opportunity for regulators worldwide to develop and propose a global regulatory science agenda for vaccines. Regulatory oversight is critical to allow access to vaccines that are safe, effective, and of assured quality. Methods used by regulators need to constantly evolve so that scientific and technological advances are applied to address challenges such as new products and technologies, and also to provide an increased understanding of benefits and risks of existing products. Regulatory science builds on high-quality basic research, and encompasses at least two broad categories. First, there is laboratory-based regulatory science. Illustrative examples include development of correlates of immunity; or correlates of safety; or of improved product characterization and potency assays. Included in such science would be tools to standardize assays used for regulatory purposes. Second, there is science to develop regulatory processes. Illustrative examples include adaptive clinical trial designs; or tools to analyze the benefit-risk decision-making process of regulators; or novel pharmacovigilance methodologies. Included in such science would be initiatives to standardize regulatory processes (e.g., definitions of terms for adverse events [AEs] following immunization). The aim of a global regulatory science agenda is to transform current national efforts, mainly by well-resourced regulatory agencies, into a coordinated action plan to support global immunization goals. This article provides examples of how regulatory science has, in the past, contributed to improved access to vaccines, and identifies gaps that could be addressed through a global regulatory science agenda. The article also identifies challenges to implementing a regulatory science agenda and proposes strategies and actions to fill these gaps. A global regulatory science agenda will enable

The regulatory effect of miRNAs is a heritable genetic trait in humans

Directory of Open Access Journals (Sweden)

Geeleher Paul

2012-08-01

Full Text Available Abstract Background microRNAs (miRNAs have been shown to regulate the expression of a large number of genes and play key roles in many biological processes. Several previous studies have quantified the inhibitory effect of a miRNA indirectly by considering the expression levels of genes that are predicted to be targeted by the miRNA and this approach has been shown to be robust to the choice of prediction algorithm. Given a gene expression dataset, Cheng et al. defined the regulatory effect score (RE-score of a miRNA as the difference in the gene expression rank of targets of the miRNA compared to non-targeted genes. Results Using microarray data from parent-offspring trios from the International HapMap project, we show that the RE-score of most miRNAs is correlated between parents and offspring and, thus, inter-individual variation in RE-score has a genetic component in humans. Indeed, the mean RE-score across miRNAs is correlated between parents and offspring, suggesting genetic differences in the overall efficiency of the miRNA biogenesis pathway between individuals. To explore the genetics of this quantitative trait further, we carried out a genome-wide association study of the mean RE-score separately in two HapMap populations (CEU and YRI. No genome-wide significant associations were discovered; however, a SNP rs17409624, in an intron of DROSHA, was significantly associated with mean RE-score in the CEU population following permutation-based control for multiple testing based on all SNPs mapped to the canonical miRNA biogenesis pathway; of 244 individual miRNA RE-scores assessed in the CEU, 214 were associated (p p = 0.04 with mean RE-score in the YRI population. Interestingly, the same SNP was associated with 17 (8.5% of all expressed miRNA expression levels in the CEU. We also show here that the expression of the targets of most miRNAs is more highly correlated with global changes in miRNA regulatory effect than with the expression of

Generally, self-renewal of spermatogonial stem cells (SSCs) is maintained in vivo in a three-dimensional (3D) microenvironment consisting of the seminiferous tubule basement membrane, indicating the importance of the 3D microenvironment for in vitro culture of SSCs. Here, we report a 3D culture microenvironment that effectively maintains porcine SSC self-renewal during culture. Porcine SSCs were cultured in an agarose-based 3D hydrogel and in 2D culture plates either with or without feeder cells. Subsequently, the effects of 3D culture on the maintenance of undifferentiated SSCs were identified by analyzing cell colony formation and morphology, AP activity, and transcriptional and translational regulation of self-renewal-related genes and the effects on proliferation by analyzing cell viability and single cell-derived colony number. The 3D culture microenvironment constructed using a 0.2% (w/v) agarose-based 3D hydrogel showed the strongest maintenance of porcine SSC self-renewal and induced significant improvements in proliferation compared with 2D culture microenvironments. These results demonstrate that self-renewal of porcine SSCs can be maintained more effectively in a 3D than in a 2D culture microenvironment. Moreover, this will play a significant role in developing novel culture systems for SSCs derived from diverse species in the future, which will contribute to SSC-related research. © 2017 International Federation for Cell Biology.

Two experiments investigated the effects of musicality and motivational orientation on auditory category learning. In both experiments, participants learned to classify tone stimuli that varied in frequency and duration according to an initially unknown disjunctive rule; feedback involved gaining points for correct responses (a gains reward structure) or losing points for incorrect responses (a losses reward structure). For Experiment 1, participants were told at the start that musicians typically outperform nonmusicians on the task, and then they were asked to identify themselves as either a "musician" or a "nonmusician." For Experiment 2, participants were given either a promotion focus prime (a performance-based opportunity to gain entry into a raffle) or a prevention focus prime (a performance-based criterion that needed to be maintained to avoid losing an entry into a raffle) at the start of the experiment. Consistent with a regulatory-fit hypothesis, self-identified musicians and promotion-primed participants given a gains reward structure made more correct tone classifications and were more likely to discover the optimal disjunctive rule than were musicians and promotion-primed participants experiencing losses. Reward structure (gains vs. losses) had inconsistent effects on the performance of nonmusicians, and a weaker regulatory-fit effect was found for the prevention focus prime. Overall, the findings from this study demonstrate a regulatory-fit effect in the domain of auditory category learning and show that motivational orientation may contribute to musician performance advantages in auditory perception.

Management systems for regulatory authorities

International Nuclear Information System (INIS)

Mpandanyama, Rujeko Lynette

2015-02-01

For a regulatory body to fulfil its statutory obligations, there is need to develop and implement a regulatory management system that has the necessary arrangements for achieving and maintaining high quality performance in regulating the safety of nuclear and radiation facilities under its authority. Hence, the regulatory management system needs to fully integrate the human resources, processes and physical resources of the organization. This study sought to provide an understanding of the concept, principles, policies and fundamentals of management systems as they relate to regulatory systems in the field of radiation protection and to make appropriate recommendations to ensure that an effective management system exists for the control of ionizing radiation and radiation sources and addresses all relevant stakeholders in Zimbabwe. A comparative analysis was done on the current management status and the ideal management system, which led to the identification of the gaps existing. The main key that was found to be of significance was lack of linkages between processes and management tools within the institution. (au)

Proportional-Integral-Derivative (PID) Control of Secreted Factors for Blood Stem Cell Culture.

2015-01-01

Clinical use of umbilical cord blood has typically been limited by the need to expand hematopoietic stem and progenitor cells (HSPC) ex vivo. This expansion is challenging due to the accumulation of secreted signaling factors in the culture that have a negative regulatory effect on HSPC output. Strategies for global regulation of these factors through dilution have been developed, but do not accommodate the dynamic nature or inherent variability of hematopoietic cell culture. We have developed a mathematical model to simulate the impact of feedback control on in vitro hematopoiesis, and used it to design a proportional-integral-derivative (PID) control algorithm. This algorithm was implemented with a fed-batch bioreactor to regulate the concentrations of secreted factors. Controlling the concentration of a key target factor, TGF-β1, through dilution limited the negative effect it had on HSPCs, and allowed global control of other similarly-produced inhibitory endogenous factors. The PID control algorithm effectively maintained the target soluble factor at the target concentration. We show that feedback controlled dilution is predicted to be a more cost effective dilution strategy compared to other open-loop strategies, and can enhance HSPC expansion in short term culture. This study demonstrates the utility of secreted factor process control strategies to optimize stem cell culture systems, and motivates the development of multi-analyte protein sensors to automate the manufacturing of cell therapies.

Several methicillin resistance (SCCmec) clusters characteristic of hospital-associated methicillin-resistant Staphylococcus aureus (MRSA) strains harbor the psm-mec locus. In addition to encoding the cytolysin, phenol-soluble modulin (PSM)-mec, this locus has been attributed gene regulatory functions. Here we employed genome-wide transcriptional profiling to define the regulatory function of the psm-mec locus. The immune evasion factor protein A emerged as the primary conserved and strongly regulated target of psm-mec, an effect we show is mediated by the psm-mec RNA. Furthermore, the psm-mec locus exerted regulatory effects that were more moderate in extent. For example, expression of PSM-mec limited expression of mecA, thereby decreasing methicillin resistance. Our study shows that the psm-mec locus has a rare dual regulatory RNA and encoded cytolysin function. Furthermore, our findings reveal a specific mechanism underscoring the recently emerging concept that S. aureus strains balance pronounced virulence and high expression of antibiotic resistance.

2000-12-15

This research presents a critical analysis and evaluation of principles of administrative laws in order to provide framework of structural reform on the nuclear safety regulation system. The focus of this analysis and evaluation is centered around the area of origin of regulatory administrative laws; authorities of regulation; procedures of regulatory actions; regulatory enforcement; and administrative relief system. In chapter 2 the concept of regulatory administration is analysed. Chapter 3 identifies the origin of regulatory administration and the principles of administration laws. It also examines legal nature of the nuclear safety standard. In relation to regulatory authorities. Chapter 4 identifies role and responsibility of administration authorities and institutions. It also examines fundamental principles of delegation of power. Then the chapter discusses the nuclear safety regulation authorities and their roles and responsibilities. Chapter 5 classifies and examines regulatory administration actions. Chapter 6 evaluates enforcement measure for effectiveness of regulation. Finally, chapter 7 discusses the administrative relief system for reviewing unreasonable regulatory acts.

Combined effect of regulatory polymorphisms on transcription of UGT1A1 as a cause of Gilbert syndrome

Directory of Open Access Journals (Sweden)

2010-06-01

Full Text Available Abstract Background Gilbert syndrome is caused by defects in bilirubin UDP-glucuronosyltransferase (UGT1A1. The most common variation believed to be involved is A(TA7TAA. Although several polymorphisms have been found to link with A(TA7TAA, the combined effect of regulatory polymorphisms in the development of Gilbert syndrome remains unclear. Methods In an analysis of 15 patients and 60 normal subjects, we detected 14 polymorphisms and nine haplotypes in the regulatory region. We classified the 4-kbp regulatory region of the patients into: the TATA box including A(TA7TAA; a phenobarbital responsive enhancer module including c.-3275T>G; and a region including other ten linked polymorphisms. The effect on transcription of these polymorphisms was studied. Results All haplotypes with A(TA7TAA had c.-3275T>G and additional polymorphisms. In an in-vitro expression study of the 4-kbp regulatory region, A(TA7TAA alone did not significantly reduce transcription. In contrast, c.-3275T>G reduced transcription to 69% of that of wild type, and the linked polymorphisms reduced transcription to 88% of wild type. Transcription of the typical regulatory region of the patients was 56% of wild type. Co-expression of constitutive androstane receptor (CAR increased the transcription of wild type by a factor of 4.3. Each polymorphism by itself did not reduce transcription to the level of the patients, however, even in the presence of CAR. Conclusions These results imply that co-operation of A(TA7TAA, c.-3275T>G and the linked polymorphisms is necessary in causing Gilbert syndrome.

The objectives of the present study were to investigate the effects of vascular endothelial growth factor (VEGF) on progesterone (P4) synthesis in cultured luteal cells from different stages of the estrous cycle and on expression of steroidogenic acute regulatory protein (STARD1), cytochrome P450 cholesterol side chain cleavage (CYP11A1) and 3β-hydroxysteroid dehydrogenase (HSD3B), antiapoptotic gene PCNA, and proapoptotic gene BAX in luteal cells obtained from mid-luteal phase (MLP) of estrous cycle in buffalo. Corpus luteum samples from the early luteal phase (ELP; day 1st-4th; n=4), MLP (day 5th-10th; n=4), and the late luteal phase (LLP; day 11th-16th; n=4) of oestrous cycle were obtained from a slaughterhouse. Luteal cell cultures were treated with VEGF (0, 1, 10 and 100 ng/ml) for 24, 48 and 72h. Progesterone was assessed by RIA, while mRNA expression was determined by quantitative real-time PCR (qRT-PCR). Results indicated a dose- and time-dependent stimulatory effect of VEGF on P4 synthesis and expression of steroidogenic enzymes. Moreover, VEGF treatment led to an increase in PCNA expression and decrease in BAX expression. In summary, these findings suggest that VEGF acts locally in the bubaline CL to modulate steroid hormone synthesis and cell survivability, which indicates that this factor has an important role as a regulator of CL development and function in buffalo.

The pleasures and pains of distinct self-construals: the role of interdependence in regulatory focus.

Science.gov (United States)

Lee, A Y; Aaker, J L; Gardner, W L

2000-06-01

Regulatory focus theory distinguishes between self-regulatory processes that focus on promotion and prevention strategies for goal pursuit. Five studies provide support for the hypothesis that these strategies differ for individuals with distinct self-construals. Specifically, individuals with a dominant independent self-construal were predicted to place more emphasis on promotion-focused information, and those with a dominant interdependent self-construal on prevention-focused information. Support for this hypothesis was obtained for participants who scored high versus low on the Self-Construal Scale, participants who were presented with an independent versus interdependent situation, and participants from a Western versus Eastern culture. The influence of interdependence on regulatory focus was observed in both importance ratings of information and affective responses consistent with promotion or prevention focus.

From regulations towards radiation protection culture

International Nuclear Information System (INIS)

Boehler, M.C.

1996-01-01

Compliance with the technical standards and specifications is a necessary but not sufficient condition for quality in radiation protection. Reaching this quality objective is not a matter of forcing improvements by a regulatory policy of reducing dose limits, but of promoting a real radiation protection culture. The spread of such a radiological protection culture encourages the deliberate adoption in everyday practice of behaviour likely to reduce exposure to ionizing radiation as loser as reasonably achievable. The aim of this paper is to demonstrate that the need to diffuse a radiological protection culture is inspired by the philosophy behind the system recommended by ICPR Publication 60 on the management of residual radiological risk and, in particular by the behavioural and incentive approach implied by the optimization principle. Special attention will be given to the fundamentals likely to contribute in a definition of radiation protection culture. (author)

Full Text Available Unsatisfactory effects of treatment of laryngeal carcinoma patients stimulate the clinicians as well as researchers to develop new more effective treatment models and to find new reliable prognostic factors. The aim of the present study was the evaluation of the use of primary cell cultures of the laryngeal carcinoma and laser scanning cytometry (LSC in the assessment of tumor reactivity to cisplatinum. Nineteen primary cultures of laryngeal carcinoma cells established from fragments of laryngeal carcinoma infiltrations were cultured with or without cisplatin, stained with monoclonal antibodies against P53 and BCL-2 proteins and analyzed by LSC. Cisplatin added to the culture medium leads to the significant increase of P53 expression and decrease of BCL-2 expression. Moreover, changes of P53 and BCL-2 expressions were significantly correlated. Our findings of apoptosis regulatory mechanisms could be useful in patient qualification for the chemotherapeutic follow-up treatment.

Do hedonic motives moderate regulatory focus motives? Evidence from the framing of persuasive messages.

Science.gov (United States)

Malaviya, Prashant; Brendl, C Miguel

2014-01-01

Research on regulatory focus has established a regulatory matching effect: The persuasiveness of a message is enhanced when regulatory orientations of message and perceiver match (i.e., both are promotion or both are prevention). We report evidence that varying the hedonic outcome reverses this effect. We manipulated hedonic outcome by explicitly stating pleasurable versus painful outcomes as part of the message frame as well as by priming perceivers to focus on either pleasurable or painful outcomes. When both message and perceiver were focused on pleasurable outcomes, we replicated the regulatory matching effect. However, the matching effect reversed when the hedonic outcome of the message was opposed to that of the perceiver (i.e., one was pleasurable and the other painful). Under these conditions, messages that mismatched the perceivers' regulatory orientation were more persuasive (i.e., promotion message for a prevention oriented perceiver or vice versa). We also examined the persuasion effects when both message and perceiver were focused on painful outcomes and found that the regulatory matching effect re-emerged. The reversal of the regulatory matching effect by hedonic outcome strongly suggests that hedonic motives (approach of pleasure vs. avoidance of pain) and regulatory focus motives are distinct constructs. This is important because contrary to theoretical statements these constructs have often been confounded.

Safety culture: a survey of the state-of-the-art

International Nuclear Information System (INIS)

Sorensen, J.N.

2002-01-01

This paper discusses the evolution of the term 'safety culture' and the perceived relationship between safety culture and safety of operations in nuclear power generation and other hazardous technologies. There is a widespread belief that safety culture is an important contributor to safety of operations. Empirical evidence that safety culture and other management and organizational factors influence operational safety is more readily available for the chemical process industry than for nuclear power plant operations. The commonly accepted attributes of safety culture include good organizational communications, good organizational learning, and senior management commitment to safety. Safety culture may be particularly important in reducing latent errors in complex, well-defended systems. The role of regulatory bodies in fostering strong safety cultures remains unclear, and additional work is required to define the essential attributes of safety culture and to identify reliable performance indicators

IAEA Mission Concludes Peer Review of UK's Nuclear Regulatory Framework

Full text: Senior international nuclear safety and radiation protection experts today concluded a ten-day International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety in the United Kingdom (UK). The Integrated Regulatory Review Service (IRRS) mission team said in its preliminary findings that the UK had made considerable progress since reviews in 2006 and 2009. It also identified good practices in the country's nuclear regulatory system. In addition to following up previous missions, a key objective was to review the effectiveness of the role of the Office of Nuclear Regulation (ONR), the UK's nuclear regulator, in ensuring the safety of radioactive waste management and decommissioning, occupational radiation protection, and public and environmental exposures, including emergency planning and response. The mission also considered the response of the UK's regulatory regime to the implications of the Fukushima Daichi accident had been timely and effective. Recommendations and suggestions were made to the ONR and the Government aimed at strengthening the effectiveness of the country's regulatory framework and functions in line with IAEA Safety Standards, the control of radioactive discharges and environmental monitoring. 'The staff of ONR is clearly dedicated to their mission to secure the protection of people and society from the hazards of the nuclear industry. I am confident that ONR will use the results of this mission to further enhance their regulatory programs', said Bill Borchardt, mission leader and former Executive Director of the United States Nuclear Regulatory Commission (NRC). 'The staff were open and cooperative in their discussions; they provided the fullest practicable assistance, and accepted advice from the Team for continuous improvement in their regulatory work'. ONR's Chief Executive, John Jenkins, said that the full report of the IRRS mission will enhance regulatory effectiveness in the UK

Regulatory Risk Management of Advanced Nuclear Power Plants

International Nuclear Information System (INIS)

George, Glenn R.

2002-01-01

Regulatory risk reflects both the likelihood of adverse outcomes during regulatory interactions and the severity of those outcomes. In the arena of advanced nuclear power plant licensing and construction, such adverse outcomes may include, for example, required design changes and construction delays. These, in turn, could significantly affect the economics of the plant and the generation portfolio in which it will operate. In this paper, the author addresses these issues through the lens of risk management. The paper considers various tools and techniques of regulatory risk management, including design diversity and hedging strategies. The effectiveness of alternate approaches is weighed and recommendations are made in several regulatory contexts. (author)

Regulatory decision making by decision analyses

International Nuclear Information System (INIS)

Holmberg, J.; Pulkkinen, U.

1993-11-01

The Technical Research Centre of Finland (VTT) has studied with the Finnish Centre for Radiation and Nuclear Safety (STUK) the applicability of decision analytic approach to the treatment of nuclear safety related problems at the regulatory body. The role of probabilistic safety assessment (PSA) in decision making has also been discussed. In the study, inspectors from STUK exercised with a decision analytic approach by reoperationalizing two occurred and solved problems. The research scientist from VTT acted as systems analysts guiding the analysis process. The first case was related to a common cause failure phenomenon in solenoid valves controlling pneumatic valves important to safety of the plant. The problem of the regulatory body was to judge whether to allow continued operation or to require more detailed inspections and in which time chedule the inspections should be done. The latter problem was to evaluate design changes of external electrical grid connections after a fire incident had revealed weakness in the separation of electrical system. In both cases, the decision analysis was carried out several sessions in which decision makers, technical experts as well as experts of decision analysis participated. A multi-attribute value function was applied as a decision model so that attributes had to be defined to quantify the levels of achievements of the objectives. The attributes included both indicators related to the level of operational safety of the plant such as core damage frequency given by PSA, and indicators related to the safety culture, i.e., how well the chosen option fits on the regulatory policy.

Amherst H. Wilder Foundation's Social Adjustment Program for Southeast Asians is implementing two collaborative, best practice, mental health and substance abuse prevention service models in Minnesota. It faced several issues in effectively bridging multiple cultural groups, including building a diverse collaborative team, involving families and youth, reconciling cultural variation in meeting styles, and making best practice models culturally appropriate. Researchers and program staff used multiple strategies to address these challenges and build successful partnerships. Through shared goals, flexibility, and a willingness to explore and address challenges, collaboratives can promote stronger relationships across cultural communities and improve their service delivery systems.

The US domestic uranium industry is at a crossroads. Historic low prices for uranium, combined with stringent and often irrational regulatory requirements, pose a very real threat to the industry's continued viability. The Nuclear Regulatory Commission has taken a number of innovative steps to reform and rationalize its regulatory programme. However, if the domestic uranium recovery industry is to remain viable, additional steps toward innovation and reform are needed, and effective implementation of reforms adopted by the Commission is essential.

The Impacts of Human Visitation on Mussel Bed Communities Along the California Coast: Are Regulatory Marine Reserves Effective in Protecting These Communities?

Science.gov (United States)

Smith, Jayson R.; Fong, Peggy; Ambrose, Richard F.

2008-04-01

Rocky intertidal habitats frequently are used by humans for recreational, educational, and subsistence-harvesting purposes, with intertidal populations damaged by visitation activities such as extraction, trampling, and handling. California Marine Managed Areas, particularly regulatory marine reserves (MRs), were established to provide legal protection and enhancement of coastal resources and include prohibitions on harvesting intertidal populations. However, the effectiveness of MRs is unclear as enforcement of no-take laws is weak and no regulations protect intertidal species from other detrimental visitor impacts such as trampling. The goal of this study was two-fold: (1) to determine impacts from human visitation on California mussel populations ( Mytilus californianus) and mussel bed community diversity; and (2) to investigate the effectiveness of regulatory MRs in reducing visitor impacts on these populations. Surveys of mussel populations and bed-associated diversity were compared: (1) at sites subjected to either high or low levels of human use, and (2) at sites either unprotected or with regulatory protection banning collecting. At sites subjected to higher levels of human visitation, mussel populations were significantly lower than low-use sites. Comparisons of mussel populations inside and outside of regulatory MRs revealed no consistent pattern suggesting that California no-take regulatory reserves may have limited effectiveness in protecting mussel communities. In areas where many people visit intertidal habitats for purposes other than collecting, many organisms will be affected by trampling, turning of rocks, and handling. In these cases, effective protection of rocky intertidal communities requires an approach that goes beyond the singular focus on collecting to reduce the full suite of impacts.

UK professional bodies have established a number of sectorial working parties to provide guidance on the improvement of radiation safety (RS) culture in the workplace. The medical sector provides unique challenges in this regard, and the remit of the medical group was to review the current state of RS culture and to develop a framework for improvement. The review of current RS culture was based on measurable indicators, including data from regulatory inspections, personal monitoring data and incident data. An online survey to capture the RS-related views and experience of hospital staff at all levels was carried out, and the responses provided a wealth of information on RS awareness and implementation across the country. The framework for improving RS culture includes both 'top-down' initiatives to engage management and regulators, and 'bottom-up' initiatives relating to engagement and training of different staff groups. A 'Ten-point Assessment' on what constitutes a good approach to medical RS culture has been proposed, which provides a tool for management to assess RS culture in the workplace and has potential use in regulatory inspections in the UK. © The Author 2016.

Cultural regulation of emotion: individual, relational, and structural sources.

Science.gov (United States)

De Leersnyder, Jozefien; Boiger, Michael; Mesquita, Batja

2013-01-01

The most prevalent and intense emotional experiences differ across cultures. These differences in emotional experience can be understood as the outcomes of emotion regulation, because emotions that fit the valued relationships within a culture tend to be most common and intense. We review evidence suggesting that emotion regulation underlying cultural differences in emotional experience often takes place at the point of emotion elicitation through the promotion of situations and appraisals that are consistent with culturally valued relationships. These regulatory processes depend on individual tendencies, but are also co-regulated within relationships-close others shape people's environment and help them appraise events in culturally valued ways-and are afforded by structural conditions-people's daily lives "limit" the opportunities for emotion, and afford certain appraisals. The combined evidence suggests that cultural differences in emotion regulation go well beyond the effortful regulation based on display rules.

Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

Socio- cultural effects on children's initiation of joint attention

Full Text Available Exchanging gazes with a social partner in response to an event in the environment is considered an effective means to direct attention, share affective experiences and highlight a target in the environment. This behavior appears during infancy and plays an important role in children's learning and in shaping their socio-emotional development. It has been suggested that cultural values of the community affect socio-emotional development through attentional dynamics of social reference (Rogoff et al., 1993. Maturational processes of brain-circuits have been found to mediate socio-cultural learning and the behavioral manifestation of cultural norms starting at preschool age (Nelson and Guyer, 2011. The aim of the current study was to investigate the relations between cultural ecology levels and children's joint attention (JA. Initiation of JA bids was studied empirically as a function of the level of social load of the target toy (3 levels, the community level of adherence to traditional values (3 levels parental education (2 levels and gender. Sixty-two kindergarten aged children were enrolled in a structured toy-exploration task, during which they were presented with toys of various social loads, with social agents (i.e., mother and experimenter present nearby, and non-social distracters presented intermittently. Analysis of variance indicated that the child's initiation of JA towards the social partner was affected by all levels of cultural ecology (i.e., toy's social load, adherence to tradition values, parental education, gender, thus supporting the study's hypotheses. The effects were such that overall, children, particularly girls' JA initiation was augmented in social toys and moderated by the socio-cultural variables. Cultural ecology seems to be related to children's JA, thereby scaffolding initiation of social sharing cues between children and adults. JA plays a role in adjusting children's internal representations of their ecological

A comprehensive review of regulatory test methods for endocrine adverse health effects.

Development of new endocrine disruption-relevant test methods has been the subject of intensive research efforts for the past several decades, prompted in part by mandates in the 1996 Food Quality Protection Act (FQPA). While scientific understanding and test methods have advanced, questions remain on whether current scientific methods are capable of adequately addressing the complexities of the endocrine system for regulatory health and ecological risk assessments. The specific objective of this article is to perform a comprehensive, detailed evaluation of the adequacy of current test methods to inform regulatory risk assessments of whether a substance has the potential to perturb endocrine-related pathways resulting in human adverse effects. To that end,  approximately 42 existing test guidelines (TGs) were considered in the evaluation of coverage for endocrine-related adverse effects. In addition to evaluations of whether test methods are adequate to capture endocrine-related effects, considerations of further enhancements to current test methods, along with the need to develop novel test methods to address existing test method gaps are described. From this specific evaluation, up to 35 test methods are capable of informing whether a chemical substance perturbs known endocrine related biological pathways. Based on these findings, it can be concluded that current validated test methods are adequate to discern substances that may perturb the endocrine system, resulting in an adverse health effect. Together, these test methods predominantly form the core data requirements of a typical food-use pesticide registration submission. It is recognized, however, that the current state of science is rapidly advancing and there is a need to update current test methods to include added enhancements to ensure continued coverage and public health and environmental protection.

The nervous and immune systems communicate bidirectionally, utilizing diverse molecular signals including cytokines and neurotransmitters to provide an integrated response to changes in the body's internal and external environment. Although, neuro-immune interactions are becoming better understood under inflammatory circumstances and it has been evidenced that interaction between neurons and T cells results in the conversion of encephalitogenic T cells to T regulatory cells, relatively little is known about the communication between neurons and naïve T cells. Here, we demonstrate that following co-culture of naïve CD4+ T cells with superior cervical ganglion neurons, the percentage of Foxp3 expressing CD4+CD25+ cells significantly increased. This was mediated in part by immune-regulatory cytokines TGF-β and IL-10, as well as the neuropeptide calcitonin gene-related peptide while vasoactive intestinal peptide was shown to play no role in generation of T regulatory cells. Additionally, T cells co-cultured with neurons showed a decrease in the levels of pro-inflammatory cytokine IFN-γ released upon in vitro stimulation. These findings suggest that the generation of Tregs may be promoted by naïve CD4+ T cell: neuron interaction through the release of neuropeptide CGRP.

Assessing progress in the development of safety culture

Rotaru, Ioan; Ghita, Sorin

1999-01-01

The concept of safety culture was introduced by the International Nuclear Safety Advisory Group (INSAG) in the Summary Report on the Post-Accident Meeting on the Chernobyl Accident in 1986. The concept was further expanded in the 1988 INSAG-3 report, Basic Safety Principles for Nuclear Power Plants, and again in 1991 in the INSAG-4 report. Recognizing the increasing role that safety culture is expected to play in nuclear installations worldwide, the Convention on Nuclear Safety states the Contracting Parties' desire 'to promote an effective nuclear safety culture'. The concept of safety culture is defined in INSAG-4 as follows: Safety culture is that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance. Safety culture is also an amalgamation of values, standards, morals and norms of acceptable behaviour. These are aimed at maintaining a self disciplined approach to the enhancement of safety beyond legislative and regulatory requirements. Therefore, the safety culture has to be inherent in the thoughts and actions of all the individuals at every level in an organization. The leadership provided by top management is crucial. Safety culture applies to conventional and personal safety as well as nuclear safety. All safety consideration are affected by common points of beliefs, attitudes, behaviour, and cultural differences, closely linked to a shared system of values and standards. The paper poses questions and tries to find answers relative to issues like: - how to assess progress; - specific organizational indicators of a progressive safety culture; - detection of incipient weaknesses in safety culture (organizational issues, employee issues, technology issues); - revitalizing a weakened safety culture; - overall assesment of safety culture; - general evaluation model. In conclusion, there is no consistent and

Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. Great emphasis has been placed during the last years on the need to change organisational culture in order to pursue effective improvement of healthcare performance. However, the precise nature of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted has been called into question. To determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance.To examine the effectiveness of these strategies according to different patterns of organisational culture. We searched the following electronic databases for primary studies: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies, controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series analyses (ITS) meeting the quality criteria used by the Cochrane Effective Practice and Organisation of Care Group (EPOC). Studies should be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. At least two review authors independently applied the criteria for inclusion and exclusion criteria to scan titles and

Cross-cultural education in U.S. medical schools: development of an assessment tool.

Peña Dolhun, Eduardo; Muñoz, Claudia; Grumbach, Kevin

2003-06-01

Medical education is responding to an increasingly diverse population and to regulatory and quality-of-care requirements by developing cross-cultural curricula in health care. This undertaking has proved problematic because there is no consensus on what elements of cross-cultural medicine should be taught. Further, less is known about what is being taught. This study hypothesized that a tool could be developed to assess common themes, concepts, learning objectives, and methods in cross-cultural education. In 2001, 31 U.S. medical schools were invited to provide the researchers all written and/or Web-based materials related to implementing cross-cultural competency in their curricula. A tool was developed to measure teaching methods, skill sets, and eight content areas in cross-cultural education. A total of 19 medical schools supplied their curricular materials. There was considerable variation in approaches to teaching and in the content of cross-cultural education across the schools. Most emphasized teaching general themes, such as the doctor-patient relationship, socioeconomic status, and racism. Most also focused on specific cultural information about the ethnic communities they served. Few schools extensively addressed health care access and language issues. This assessment tool is an important step toward developing a standard nomenclature for measuring the success of cross-cultural education curricula. On the national level, the tool can be used to compare program components and encourage the exchange of effective teaching tools by promoting a common language, which will be essential for developing and implementing curricula, for comparing programs, and evaluating their effects on quality of care.

2000-09-01

The spread of utility liberalisation and privatisation to middle and low income developing countries raises the problem of whether and how they can establish an effective regulatory capability of whether the supply of regulatory services is likely to be insufficient. The paper presents evidence on the size of electricity regulatory agencies in 24 mainly middle and lower income countries as well as the number of high-level, specialist regulatory staff and the potential resource pool from post-school education. The paper also discusses how far the problem can be alleviated and/or avoided by the use of regulation by contract, regulation by multi-national regulatory agency or contracting-out. The paper concludes that such solutions are unlikely to be generally effective but that informal exchanges of information and pooling of resources between national regulators on a market-driven basis, as seen in Southern Africa and the EU, is a promising option. The paper concludes by pointing to the need to ascertain the minimum required regulatory capability in developing countries as perceived by Governments and potential investors. (author)

Whereas self-expression is valued in the United States, it is not privileged with such a cultural emphasis in East Asia. Four studies demonstrate the psychological implications of this cultural difference. Studies 1 and 2 found that European Americans value self-expression more than East Asians/East Asian Americans. Studies 3 and 4 examined the roles of expression in preference judgments. In Study 3, the expression of choice led European Americans but not East Asian Americans to be more invested in what they chose. Study 4 examined the connection between the value of expression and the effect of choice expression and showed that European Americans place greater emphasis on self-expression than East Asian Americans, and this difference explained the cultural difference in Study 3. This research highlights the importance of the cultural meanings of self-expression and the moderating role of cultural beliefs on the psychological effect of self-expression. 2007 APA, all rights reserved

Recent studies on animal models of diabetes as well as human regulatory T cells have shown that α impairs the ability of these cells to prevent the disease. NOD mice treated with α had decreased frequency of regulatory T cells, whereas anti-TNF administration induced the increase in the number of these cells and disease prevention. The action of α also influenced the suppressive potential of Tregs. Increased susceptibility of Tregs to the modulatory effects of α involves signaling through TNFR2 that is expressed on the surface of this cell population. It seems that α neutralization may rescue regulatory T cells and restore their function in several autoimmune and inflammatory diseases. This review describes recent data concerning regulatory T cells in the context of inflammation that is present during diabetes type 1. It describes how TNF contributes to the pathogenesis of type 1 diabetes, what is the impact of this cytokine on regulatory T cell population and therapeutic effects that result from its neutralization in several inflammatory and autoimmune diseases.

NASA Headquarters Environmental Management Division supports NASA's mission to pioneer the future in space exploration, scientific discovery, and aeronautics research by integrating environmental considerations into programs and projects early-on, thereby proactively reducing NASA's exposure to institutional, programmatic and operational risk. As part of this effort, NASA established the Principal Center for Regulatory Risk Analysis and Communication (RRAC PC) as a resource for detecting, analyzing, and communicating environmental regulatory risks to the NASA stakeholder community. The RRAC PC focuses on detecting emerging environmental regulations and other operational change drivers that may pose risks to NASA programs and facilities, and effectively communicating the potential risks. For example, regulatory change may restrict how and where certain activities or operations may be conducted. Regulatory change can also directly affect the ability to use certain materials by mandating a production phase-out or restricting usage applications of certain materials. Regulatory change can result in significant adverse impacts to NASA programs and facilities due to NASA's stringent performance requirements for materials and components related to human-rated space vehicles. Even if a regulation does not directly affect NASA operations, U.S. and international regulations can pose program risks indirectly through requirements levied on manufacturers and vendors of components and materials. For example, manufacturers can change their formulations to comply with new regulatory requirements. Such changes can require time-consuming and costly requalification certification for use in human spaceflight programs. The RRAC PC has implemented a system for proactively managing regulatory change to minimize potential adverse impacts to NASA programs and facilities. This presentation highlights the process utilized by the RRACPC to communicate regulatory change and the associated

Progesterone is an important steroid hormone in the regulation of the bovine estrous cycle. The steroidogenic acute regulatory protein (StAR) is an indispensable component for transporting cholesterol to the inner mitochondrial membrane, which is one of the rate-limiting steps for progesterone synthesis. Low-density lipoprotein (LDL) supplies cholesterol precursors for progesterone formation, and the lysosomal degradation pathway of LDL is essential for progesterone biosynthesis in granulosa cells after ovulation. However, it is currently unknown how LDL and lysosomes coordinate the expression of the StAR gene and progesterone production in bovine granulosa cells. Here, we investigated the role of lysosomes in LDL-treated bovine granulosa cells. Our results reported that LDL induced expression of StAR messenger RNA and protein as well as expression of cholesterol side-chain cleavage cytochrome P-450 (CYP11A1) messenger RNA and progesterone production in cultured bovine granulosa cells. The number of lysosomes in the granulosa cells was also significantly increased by LDL; whereas the lysosomal inhibitor, chloroquine, strikingly abolished these LDL-induced effects. Our results indicate that LDL promotes StAR expression, synthesis of progesterone, and formation of lysosomes in bovine granulosa cells, and lysosomes participate in the process by releasing free cholesterol from hydrolyzed LDL.

Dissociated monolayer cultures of chick ciliary ganglion neurons have been used to study the effects of control and ALS sera. The cultured neurons survive and extend neurites for a minimum of 2 weeks in a standard tissue culture medium that contains 10% heat-inactivated human serum. Three parameters of the neurons have been examined when cultured in control and ALS sera for 8 to 12 days: (1) neuronal survival, (2) activity of the enzyme choline acetyltransferase, and (3) synthesis of 3 H-acetylcholine using 3 H-choline as precursor. ALS sera cause a small decrease in these three parameters, but this difference is not significant

No evidence addresses the effectiveness of patient-centered cultural competence training in non-Western settings. To examine whether a patient-centered cultural competency curriculum improves medical students' skills in eliciting the patients' perspective and exploring illness-related social factors. Fifty-seven medical students in Taiwan were randomly assigned to either the control (n = 27) or one of two intervention groups: basic (n = 15) and extensive (n = 15). Both intervention groups received two 2-hour patient-centered cultural competency workshops. In addition, the extensive intervention group received a 2-hour practice session. The control group received no training. At the end of the clerkship, all students were evaluated with an objective structured clinical examination (OSCE). Students in the extensive intervention group scored significantly higher than the basic intervention and control groups in eliciting the patient's perspective (F = 18.38, p social factors (F = 6.66, p = 0.003, eta(2) = 0.20). Patient-centered cultural competency training can produce improvement in medical students' cross-cultural communication skills in non-Western settings, especially when adequate practice is provided.

Regulatory inspection of nuclear facilities and enforcement by the regulatory body. Safety guide

International Nuclear Information System (INIS)

2002-01-01

The purpose of this Safety Guide is to provide recommendations for regulatory bodies on the inspection of nuclear facilities, regulatory enforcement and related matters. The objective is to provide the regulatory body with a high level of confidence that operators have the processes in place to ensure compliance and that they do comply with legal requirements, including meeting the safety objectives and requirements of the regulatory body. However, in the event of non-compliance, the regulatory body should take appropriate enforcement action. This Safety Guide covers regulatory inspection and enforcement in relation to nuclear facilities such as: enrichment and fuel manufacturing plants; nuclear power plants; other reactors such as research reactors and critical assemblies; spent fuel reprocessing plants; and facilities for radioactive waste management, such as treatment, storage and disposal facilities. This Safety Guide also covers issues relating to the decommissioning of nuclear facilities, the closure of waste disposal facilities and site rehabilitation. Section 2 sets out the objectives of regulatory inspection and enforcement. Section 3 covers the management of regulatory inspections. Section 4 covers the performance of regulatory inspections, including internal guidance, planning and preparation, methods of inspection and reports of inspections. Section 5 deals with regulatory enforcement actions. Section 6 covers the assessment of regulatory inspections and enforcement activities. The Appendix provides further details on inspection areas for nuclear facilities

The present study assessed the extent to which culture impacts the emotion-induced memory trade-off effect. This trade-off effect occurs because emotional items are better remembered than neutral ones, but this advantage comes at the expense of memory for backgrounds such that neutral backgrounds are remembered worse when they occurred with an emotional item than with a neutral one. Cultures differ in their prioritisation of focal object versus contextual background information, with Westerners focusing more on objects and Easterners focusing more on backgrounds. Americans, a Western culture, and Turks, an Eastern-influenced culture, incidentally encoded positive, negative, and neutral items placed against neutral backgrounds, and then completed a surprise memory test with the items and backgrounds tested separately. Results revealed a reduced trade-off for Turks compared to Americans. Although both groups exhibited an emotional enhancement in item memory, Turks did not show a decrement in memory for backgrounds that had been paired with emotional items. These findings complement prior ones showing reductions in trade-off effects as a result of task instructions. Here, we suggest that a contextual-focus at the level of culture can mitigate trade-off effects in emotional memory.

Communication is essential to safe flight, as evidenced by several accidents in which crew communicates was found to have contributed to the accidents. This chapter documents the essential role of explicit efficient communication to flight safety with a global context. It addresses communication between flight crews and air traffic controllers in regions a the world where pilots and controllers speak different native languages, as well as cases in which crew members within the flight deck represent different native languages and cultures. It also addresses problems associated with "exporting" crew resource management training programs to parts of the world which values and norms differ from those of the United States, where these programs were initially developed. This chapter is organized around several central questions: (1) What are various kinds of communication failures and what are their consequences; (2) What are the causes of communication failure; (3) What are features of effective crew communication; (4) What can be done to enhance communication success? To explore a wider range of communication failures than available from accident reports, we examined a set of incident reports from the Aviation Safety Reporting System. These could be classified into three major categories: those in which language actually interfered with transmission of a message; those in which transmission was adequate but the context was not expressed unambiguously and thus the message received was not the same as the message intended; and those in which the message was received as intended, but was not adequately understood or acted upon, mainly because of cultural factors. The consequences of failed communication can be flight errors (such as when a clearance is not received correctly), loss of situation awareness, or failure of crew members (or ATC and pilots) to build a shared understanding of a situation. Causes of misunderstanding can be traced to a number of sources, often

In-operation regulatory activities at sites are very important and it should be improved to cope with accidents efficiently and quickly. In case of site survey and safety regulatory inspection regulatory system based on not regulatory headquarter but site regional office should be constructed. In other words, safety assurance and pending problem management considering site situation are needed. In this study, regulatory system at Nuclear Power Plant sites all over the world were reviewed and effective regulatory system of Korea are suggested to maximize the efficiency of license and regulatory manpower and consider the interest of local government and residents.

Aspergillus oryzae produces a large amount of secreted proteins in solid-state culture, and some proteins such as glucoamylase (GlaB) and acid protease (PepA) are specifically produced in solid-state culture, but rarely in submerged culture. From the disruption mutant library of A. oryzae transcriptional regulators, we successfully identified a disruption mutant showing an extremely low production level of GlaB but a normal level of α-amylase production. This strain was a disruption mutant of the C2H2-type transcription factor, FlbC, which is reported to be involved in the regulation of conidiospore development. Disruption mutants of other upstream regulators comprising a conidiation regulatory network had no apparent effect on GlaB production in solid-state culture. In addition to GlaB, the production of acid protease in solid-state culture was also markedly decreased by flbC disruption. Northern blot analyses revealed that transcripts of glaB and pepA were significantly decreased in the flbC disruption strain. These results suggested that FlbC is involved in the transcriptional regulation of genes specifically expressed under solid-state cultivation conditions, possibly independent of the conidiation regulatory network.
