Scholars (e.g., Bemak & Chung, 2004) underscore the need for group workers to be culturally sensitive. One group training strategy, cultural immersion, is often employed to develop cultural sensitivity. However, no studies have utilized quasi-experimental methodologies to assess differences in cultural sensitivity between trainees that immerse…

Accumulating evidence suggests that North Americans tend to focus on central objects whereas East Asians tend to pay more attention to contextual information in a visual scene. Although it is generally believed that such culturally divergent attention tendencies develop through socialization, existing evidence largely depends on adult samples. Moreover, no past research has investigated the relation between context-sensitivity and other domains of cognitive development. The present study examined children in the United States and Japan (N = 175, age 4-9 years) to investigate the developmental pattern in context-sensitivity and its relation to executive function. The study found that context-sensitivity increased with age across cultures. Nevertheless, Japanese children showed significantly greater context-sensitivity than American children. Also, context-sensitivity fully mediated the cultural difference in a set-shifting executive function task, which might help explain past findings that East Asian children outperformed their American counterparts on executive function. © 2012 Blackwell Publishing Ltd.

Australia's immigration policy has generated a rich diverse cultural community of staff and patients in critical care environments. Many different cultural perspectives inform individual actions in the context of critical care, including the highly sensitive area of end of life care, with nurses feeling poorly prepared to provide culturally sensitive end of life care. This article describes and evaluates the effectiveness of an educational innovation designed to develop graduate-level critical care nurses' capacity for effective interpersonal communication, as members of a multi-disciplinary team in providing culturally sensitive end-of-life care. A mixed method pilot study was conducted using a curriculum innovation intervention informed by The Excellence in Cultural Experiential Learning and Leadership Program (EXCELL),(1) which is a higher education intervention which was applied to develop the nurses' intercultural communication skills. 12 graduate nursing students studying critical care nursing participated in the study. 42% (n=5) of the participants were from an international background. Information about students' cultural learning was recorded before and after the intervention, using a cultural learning development scale. Student discussions of end of life care were recorded at Week 2 and 14 of the curriculum. The quantitative data was analysed using descriptive statistical analysis and qualitative data was thematically analysed. Students demonstrated an increase in cultural learning in a range of areas in the pre-post surveys including understandings of cultural diversity, interpersonal skills, cross cultural interactions and participating in multicultural groups. Thematic analysis of the end of life discussions revealed an increase in the levels of nurse confidence in approaching end of life care in critical care environments. The EXCELL program provides an effective and supportive educational framework to increase graduate nurses' cultural learning

The Exploration of Culturally Sensitive Nursing Care in Pediatric Setting: a Qualitative Study

Directory of Open Access Journals (Sweden)

Leila Valizadeh

2017-02-01

Full Text Available Background: One of the essential aspects of the provision of care is cultural issues. Cultural sensitivity is the key for cultural care. The aim of this study was to explore culturally sensitive care in pediatric nursing care in Iran.Materials and Methods: This study was a conventional content analysis. Participants were consisted of 25 nurses and 9 parents selected through purposive sampling from three pediatric referral centers in Tabriz and Tehran, Iran. Data was collected using semi-structured interviews and field notes and were concurrently analyzed by using Graneheim and Lundman (2004 method. Data was transcribed verbatim, words, sentences, and phrases were considered meaning units, abstracted, labeled and compared for developing categories.Results: Culturally sensitive care of a sick child was consisted of three themes: ‘cultural exposure’, ‘intercultural communication’ and ‘the reconciliation of cultural conflict in families/care’. During the ‘cultural exposure’ nurses were informed of the cultural manifestations, strived to identify and understand patients/families with cultural diversities and respect their cultural beliefs. The nurse used the native language in ‘intercultural communication’ or a combination of verbal and nonverbal communication methods to reach a common understanding. Finally, a nurse in the conflict between the culture of child/family and care took actions for making decisions to develop a compliance between care and the family culture and amended parents’ harmful desires through negotiation and appropriate care.Conclusion: Understanding the concept of culturally sensitive care, can help with resolving the problems of cultural exchanges in Pediatric wards. Providing cultural facilities and interpreters to communicate with patients/family increase their satisfaction.

Chen, Shu-Heng; Liou, Wen-Ching; Chen, Ting-Yu

The global financial crisis brought a serious collapse involving a "systemic" meltdown. Internet technology and globalization have increased the chances for interaction between countries and people. The global economy has become more complex than ever before. Mark Buchanan [12] indicated that agent-based computer models will prevent another financial crisis and has been particularly influential in contributing insights. There are two reasons why culture-sensitive agent on the financial market has become so important. Therefore, the aim of this article is to establish a culture-sensitive agent and forecast the process of change regarding herding behavior in the financial market. We based our study on the Kirman's Ant Model[4,5] and Hofstede's Natational Culture[11] to establish our culture-sensitive agent based model. Kirman's Ant Model is quite famous and describes financial market herding behavior from the expectations of the future of financial investors. Hofstede's cultural consequence used the staff of IBM in 72 different countries to understand the cultural difference. As a result, this paper focuses on one of the five dimensions of culture from Hofstede: individualism versus collectivism and creates a culture-sensitive agent and predicts the process of change regarding herding behavior in the financial market. To conclude, this study will be of importance in explaining the herding behavior with cultural factors, as well as in providing researchers with a clearer understanding of how herding beliefs of people about different cultures relate to their finance market strategies.

OBJECTIVE To assess Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity, while controlling for patients' sociodemographic, clinical, and communication factors, as well as pharmacist factors, and to identify clinical pharmacists' cultural factors that are important to Spanish-speaking patients. DESIGN Cross-sectional study. SETTING Central Texas during August 2011 to May 2012. PARTICIPANTS Spanish-speaking patients of federally qualified health centers (FQHCs). MAIN OUTCOME MEASURE(S) A Spanish-translated survey assessed Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity. RESULTS Spanish-speaking patients (N = 101) reported overall satisfaction with their clinical pharmacists' communication skills and cultural sensitivity. Patients also indicated that pharmacists' cultural rapport (e.g., ability to speak Spanish, respectfulness) was generally important to Spanish speakers. Multiple linear regression analyses showed that cultural rapport was significantly related to satisfaction with pharmacists' communication skills and demonstration of cultural sensitivity. CONCLUSION Overall, patients were satisfied with pharmacists' communication skills and cultural sensitivity. Patient satisfaction initiatives that include cultural rapport should be developed for pharmacists who provide care to Spanish-speaking patients with limited English proficiency.

Personnel from diverse ethnic and demographic backgrounds come together in both civilian and military healthcare systems, facing diagnoses that at one level are equalizers: coronary disease is coronary disease, breast cancer is breast cancer. Yet the expression of disease in individuals from different backgrounds, individual patient experience of disease as a particular illness, and interactions between patients and providers occurring in any given disease scenario, all vary enormously depending on the fortuity of the equation of "which patient happens to arrive in whose exam room." Previously, providers' absorption of lessons-learned depended on learning as an apprentice would when exposed over time to multiple populations. As a result, and because providers are often thrown into situations where communications falter through inadequate direct patient experience, diversity in medicine remains a training challenge. The questions then become: Can simulation and virtual training environments (VTEs) be deployed to short-track and standardize this sort of random-walk problem? Can we overcome the unevenness of training caused by some providers obtaining the valuable exposure to diverse populations, whereas others are left to "sink or swim"? This paper summarizes developing a computer-based VTE called TEACH (Training to Enable/Achieve Culturally Sensitive Healthcare). TEACH was developed to enhance healthcare providers' skills in delivering culturally sensitive care to African-American women with breast cancer. With an authoring system under development to ensure extensibility, TEACH allows users to role-play in clinical oncology settings with virtual characters who interact on the basis of different combinations of African American sub-cultural beliefs regarding breast cancer. The paper reports on the roll-out and evaluation of the degree to which these interactions allow providers to acquire, practice, and refine culturally appropriate communication skills and to

Effective and easy-to-use methods for detecting Clostridium difficile spore contamination would be useful for identifying environmental reservoirs and monitoring the effectiveness of room disinfection. Culture-based detection methods are sensitive for detecting C. difficile, but their utility is limited due to the requirement of anaerobic culture conditions and microbiological expertise. We developed a low-cost selective broth medium containing thioglycolic acid and l-cystine, termed C. difficile brucella broth with thioglycolic acid and l-cystine (CDBB-TC), for the detection of C. difficile from environmental specimens under aerobic culture conditions. The sensitivity and specificity of CDBB-TC (under aerobic culture conditions) were compared to those of CDBB (under anaerobic culture conditions) for the recovery of C. difficile from swabs collected from hospital room surfaces. CDBB-TC was significantly more sensitive than CDBB for recovering environmental C. difficile (36/41 [88%] versus 21/41 [51%], respectively; P = 0.006). C. difficile latex agglutination, an enzyme immunoassay for toxins A and B or glutamate dehydrogenase, and a PCR for toxin B genes were all effective as confirmatory tests. For 477 total environmental cultures, the specificity of CDBB-TC versus that of CDBB based upon false-positive yellow-color development of the medium without recovery of C. difficile was 100% (0 false-positive results) versus 96% (18 false-positive results), respectively. False-positive cultures for CDBB were attributable to the growth of anaerobic non-C. difficile organisms that did not grow in CDBB-TC. Our results suggest that CDBB-TC provides a sensitive and selective medium for the recovery of C. difficile organisms from environmental samples, without the need for anaerobic culture conditions.

Diabetes self-management education can improve outcomes in adults with Type 2 diabetes mellitus (T2DM). However, Hispanics, a group that carries a large burden of disease, may not participate in diabetes education programs. Audience engagement with entertainment-education has been associated with improved health education outcomes and may engage and empower Hispanic users to active self-care. Successful use of entertainment-education relies on the use of characters and situations with whom the viewers can feel some sense of involvement and for Hispanic audiences is encouraged when storylines and characters are culturally sensitive. In this study, we used a mixed methods approach that included descriptive statistics of closed-ended and content analysis of open-ended questions to measure the cultural sensitivity of the telenovela portion of a novel technology-based application called Sugar, Heart, and Life (SHL). Specifically, we analyzed the responses of 123 male and female patients diagnosed with uncontrolled T2DM to determine viewer involvement with characters and situations in the telenovela, viewer perceived self-efficacy in following recommendations, as well as viewer satisfaction with the program. Our findings indicate that the SHL application achieved its goal of creating a user-friendly program that depicted realistic, culturally sensitive characters and storylines that resonated with Hispanic audiences and ultimately fostered perceived self-efficacy related to following recommendations given about healthy lifestyle changes for diabetes self-management. These findings suggest that the SHL application is a culturally sensitive health education intervention for use by Hispanic male and female individuals that may empower them in self-management of T2DM.

Chinese hamster ovary (CHO) cells have been widely used for producing many recombinant therapeutic proteins. Constraint-based modeling, such as flux balance analysis (FBA) and metabolic flux analysis (MFA), has been developing rapidly for the quantification of intracellular metabolic flux distribution at a systematic level. Such methods would produce detailed maps of flows through metabolic networks, which contribute significantly to better understanding of metabolism in cells. Although these approaches have been extensively established in microbial systems, their application to mammalian cells is sparse. This review brings together the recent development of constraint-based models and their applications in CHO cells. The further development of constraint-based modeling approaches driven by multi-omics datasets is discussed, and a framework of potential modeling application in cell culture engineering is proposed. Improved cell culture system understanding will enable robust developments in cell line and bioprocess engineering thus accelerating consistent process quality control in biopharmaceutical manufacturing. © 2017 Wiley Periodicals, Inc.

Eventhough they have interest in this Malay culture, they have not found an app or media that can attract attention. Thus, they ask if the application of Malay culture can add game content later, eg War games using background and other elements related to Malay culture.

Culture-sensitive neural substrates of human cognition: a transcultural neuroimaging approach.

Science.gov (United States)

Han, Shihui; Northoff, Georg

2008-08-01

Our brains and minds are shaped by our experiences, which mainly occur in the context of the culture in which we develop and live. Although psychologists have provided abundant evidence for diversity of human cognition and behaviour across cultures, the question of whether the neural correlates of human cognition are also culture-dependent is often not considered by neuroscientists. However, recent transcultural neuroimaging studies have demonstrated that one's cultural background can influence the neural activity that underlies both high- and low-level cognitive functions. The findings provide a novel approach by which to distinguish culture-sensitive from culture-invariant neural mechanisms of human cognition.

In increasingly globalized societies, patient-centered cancer care requires culture-sensitive approaches in order to ensure patients well-being. While migrant patients' needs are frequently reported in the literature, staff members' perception of work with migrant patients, associated challenges, or individual work approaches are largely unknown. This study addresses this research gap through qualitative exploration of experiences of multicultural health care professionals in supportive oncology and palliative care, working with patients from different cultural backgrounds. This study aims to understand staff experience of the impact of culture on cancer care. This study was conducted at the Medical University of Vienna, including staff from different settings of oncology and palliative care, in different professional positions, and with a range of individual migration backgrounds. Semistructured interviews were conducted with 21 staff members working with patients from different cultural backgrounds. Interviews explored views on the impact of culture on care were audio-taped, transcribed, and analyzed using a rigorous method of thematic analysis, enhanced with grounded theory techniques. Interviews revealed 4 key topics: culture-specific differences, assumed reasons for differences, consequences of multicultural care, and tools for culture-sensitive care. Strategies to better deal with migrant patients and their families were suggested to improve work satisfaction amongst staff. This study identifies relevant staff challenges in work with migrant patients. Concrete suggestions for improvement include measures on an organizational level, team level, and personal tools. The suggested measures are applicable to improve work satisfaction and culture-sensitive care not only in cancer care but also in other areas of medicine. Copyright © 2016 John Wiley & Sons, Ltd.

2012-01-01

Full Text Available The paper presents a review of studies about the visible-light-promoted photodegradation of the contaminants and energy conversion with sensitized photocatalysts. Herein we studied mechanism, physical properties, and synergism effect of the sensitized photocatalysts as well as the method for enhancing the photosensitized effect. According to the reported studies in the literature, inorganic sensitizers, organic dyes, and coordination metal complexes were very effective sensitizers that were studied mostly, of which organic dyes photosensitization is the most widely studied modified method. Photosensitization is an important way to extend the excitation wavelength to the visible range, and therefore sensitized photocatalysts play an important role in the development of visible light-responsive photocatalysts for future industrialized applications. This paper mainly describes the types, modification, photocatalytic performance, application, and the developments of photosensitization for environmental application.

Full Text Available Marine spatial planning has become the crucial issues for an archipelagic state such as Indonesia. The global market demand on marine economic species has been initiated the exploitation of the marine species which will become the hindrance in maintaining the sustainable marine biodiversity. Besides that, the degradation of marine species will also become the problem for traditional fishermen. Therefore, a model has to be employed to spatially manage the coastal waters as the alternative for fishermen activities during closed seasons, such as floating fish net culture.  The aim of this study was to develop marine spatial planning model based on ecological approach in order to identify the potentiality of marine waters for marine culture such as floating fish net culture. The method for the model consisted of social assessment using the Delphi for developing the rule of marine planning for floating fish net culture and the spatial analysis technique for determining the model of marine spatial planning for floating fish net culture. The area of Kupang Bay waters, East Nusa Tenggara was used as the study area. The result indicated that the model can be used to sustainable marine spatial planning, especially for floating fish net culture. The model considered the aspects of potential area for marine culture, the management of zonation and transportation lanes, the conservation and protected area and the strategic area. Application in Kupang bay illustrated the aspect of technology input such as raceways since the majority of the area of Kupang Bay waters is classified as medium potential. Further research still needs to optimum the application of model to others marine area.

Prenatal expectations describe various domains a woman envisions in preparation for her role as a new mother and influence how women transition into the maternal role. Although the maternal role is strongly influenced by the prevailing familial and sociocultural context, research characterizing prenatal expectations in ethnic minority and low-income women is lacking. As part of the largest growing minority group in the USA, Latina mothers represent an important group to study. Two hundred and ten low-income Mexican American women were administered the Prenatal Experiences Scale for Mexican Americans (PESMA) that was adapted to capture specific cultural aspects of prenatal expectations. Measures of current support, prenatal depressive symptoms, and other sociodemographic characteristics were also completed to assess validity. Exploratory factor analysis identified three underlying factors of prenatal expectations: paternal support, family support, and maternal role fulfillment. Associations among these subscales and demographic and cultural variables were conducted to characterize women who reported higher and lower levels of expectations. The PESMA demonstrated good concurrent validity when compared to measures of social support, prenatal depressive symptoms, and other sociodemographic constructs. A culturally sensitive measure of prenatal expectations is an important step towards a better understanding of how Mexican American women transition to the maternal role and identify culturally specific targets for interventions to promote maternal health.

Stanciu, Adrian; Cohrs, J Christopher; Hanke, Katja; Gavreliuc, Alin

2017-01-01

There is little and unsystematic evidence about whether the content of stereotypes can vary within a culture. Using the Stereotype Content Model (SCM) as a theoretical framework, in two studies we examined the content of stereotypes in an Eastern European culture, namely Romania. Data were collected from four regions prototypical in terms of economic and social development in Romania, and we examined whether the content of stereotypes varies across these regions. As expected, the findings confirm the applicability of the SCM in Romania to reveal culture-specific stereotypes and provide initial support for within-culture variation in the content of stereotypes. We discuss, in particular, possible reasons for two main findings: a strong one-dimensional structure of stereotypes, and regional differences in stereotype content.

This study was part of a double-blind randomised controlled trial aimed to evaluate the effects of culture-sensitive patient information materials (PIM) compared with standard translated material. The study aimed to obtain the data for the development of culture sensitive PIM about unipolar depression for the 4 largest migrant groups in Germany (Turkish, Polish, Russian and Italian migration background). A qualitative study using 4 manual-based focus groups (FG), one for each migrant group, with 29 participants (9 with a Turkish (TüG), 8 with a Polish (PoG), 5 with a Russian (RuG) and 7 with an Italian (ItG) migration background) was conducted. The discussions were recorded, transcribed and analyzed using qualitative content analysis. 7 categories were identified. For the (1.) development of a good culture-sensitive PIM an easy language, a clear structure, an assessable extent of information and the avoidance of stereotypes were highlighted cross-culturally in all four FG. RuG and PoG had the largest (2.) lack of information about the German health care system. Concerning the (3.) illness perception RuG named problems with recognizing and understanding depression. PoG, RuG and TüG thematized (4.) feared consequences of the illness and of professional helpseeking. ItG, PoG, RuG had fears concerning (5.) psychotropic drugs as a result from insufficient knowledge about medication. For (6.) doctor-patient relationship cultural specifics were identified in RuG and TüG and for (7.) migration or culture specific reasons for depression in RuG, ItG and TüG. Although the identified categories were relevant for all or for the majority of migrant groups, for most categories specific cultural aspects were discovered. These findings show the importance of a culture sensitive adaptation of PIM. © Georg Thieme Verlag KG Stuttgart · New York.

Culture-bound syndrome and a culturally sensitive approach: from a viewpoint of medical anthropology.

Science.gov (United States)

Shimoji, A; Miyakawa, T

2000-08-01

Some aspects of the culture-bound syndrome are presented for discussion. From the psychiatric and medical anthropological viewpoints, kamidaari is described as an initiatory illness for seeing a shaman, and focus on clinical realities developing between different therapeutic subcultures in the same culture and the complementary practices of two epistemological ones, namely, the shamanistic and modern psychiatric system in the shamanistic climate. It is suggested that the culture-bound syndrome that reflects cultural influences on disease patterns and renders them difficult to place in a universal classificatory system should be seen as a vernacular bricolage or as tactics used by people within the web of their own local culture of origin. Therapists who treat patients in a cross-epistemological milieu should be aware of the subcultural-epistemological issues that may affect the clinical process. It should be recognized that, depending on the nature of a particular psychiatric crisis, the clinical encounter is straddling the boundaries of multiple clinical realities. At every stage in the clinical field, there is an intersection, consonance, or interruption of rejoinders in the open dialog by all those engaged in the clinical time. Aspects of climatic, culturally sensitive psychotherapy will be described, and the concept of the culture-bound syndrome will be reconsidered. Our approach could be seen as 'situation- and fudo-bound'.

Teaching ethics: when respect for autonomy and cultural sensitivity collide.

Science.gov (United States)

Minkoff, Howard

2014-04-01

Respect for autonomy is a key ethical principle. However, in some cultures other moral domains such as community (emphasizing the importance of family roles) and sanctity (emphasizing the sacred and the spiritual side of human nature) hold equal value. Thus, an American physician may sometimes perceive a conflict between the desire to practice ethically and the wish to be sensitive to the mores of other cultures. For example, a woman may appear to be making what the physician thinks is a bad clinical choice because her spouse is speaking on her behalf. That physician may find it difficult to reconcile the sense that the patient had not exercised freely her autonomy with the desire to be culturally sensitive. In this article, the means by which a physician can reconcile respect for other cultures with respect for autonomy is explored. The question of whether physicians must always defer to patients' requests solely because they are couched in the language of cultural sensitivity is also addressed. Copyright © 2014 Mosby, Inc.

There is a need for rapid, efficient and cost-effective alternatives to traditional in vivo developmental neurotoxicity testing. In vitro cell culture models can recapitulate many of the key cellular processes of nervous system development, including neurite outgrowth, and may be used as screening tools to identify potential developmental neurotoxicants. The present study compared primary rat cortical cultures and human embryonic stem cell-derived neural cultures in terms of: 1) reproducibility of high content image analysis based neurite outgrowth measurements, 2) dynamic range of neurite outgrowth measurements and 3) sensitivity to chemicals which have been shown to inhibit neurite outgrowth. There was a large increase in neurite outgrowth between 2 and 24 h in both rat and human cultures. Image analysis data collected across multiple cultures demonstrated that neurite outgrowth measurements in rat cortical cultures were more reproducible and had higher dynamic range as compared to human neural cultures. Human neural cultures were more sensitive than rat cortical cultures to chemicals previously shown to inhibit neurite outgrowth. Parallel analysis of morphological (neurite count, neurite length) and cytotoxicity (neurons per field) measurements were used to detect selective effects on neurite outgrowth. All chemicals which inhibited neurite outgrowth in rat cortical cultures did so at concentrations which did not concurrently affect the number of neurons per field, indicating selective effects on neurite outgrowth. In contrast, more than half the chemicals which inhibited neurite outgrowth in human neural cultures did so at concentrations which concurrently decreased the number of neurons per field, indicating that effects on neurite outgrowth were secondary to cytotoxicity. Overall, these data demonstrate that the culture models performed differently in terms of reproducibility, dynamic range and sensitivity to neurite outgrowth inhibitors. While human neural

In Japan, after the Hanshin-Awaji earthquake, applications of anti-seismic systems have been much progressed. New design codes for base-isolated buildings were enacted in 2000. The objects of seismic isolation technologies expanded. The seismic isolation began to be used for structures such as high-rise building, artificial grounds for multiple buildings and cultural heritages, in addition to normal office buildings and residential ones. The seismic isolation also began to be used for industrial buildings such as semiconductor manufacturing factories which contain very sensitive equipment.This paper describes the current status of development and application of antiseismic systems to buildings, cultural heritage and industrial facilities in Japan

Low-melting-point substances are widely used to develop temperature-sensitive formulations. In this study, we focused on microcrystalline wax (MCW) as a low-melting-point substance. We evaluated the drug release behavior of wax matrix (WM) particles using various MCW under various temperature conditions. WM particles containing acetaminophen were prepared using a spray congealing technique. In the dissolution test at 37°C, WM particles containing low-melting-point MCWs whose melting was starting at approx. 40°C (Hi-Mic-1045 or 1070) released the drug initially followed by the release of only a small amount. On the other hand, in the dissolution test at 20 and 25°C for WM particles containing Hi-Mic-1045 and at 20, 25, and 30°C for that containing Hi-Mic-1070, both WM particles showed faster drug release than at 37°C. The characteristic drug release suppression of WM particles containing low-melting-point MCWs at 37°C was thought attributable to MCW melting, as evidenced by differential scanning calorimetry analysis and powder X-ray diffraction analysis. Taken together, low-melting-point MCWs may be applicable to develop implantable temperature-sensitive formulations that drug release is accelerated by cooling at administered site.

Sergueev, Kirill V; Filippov, Andrey A; Nikolich, Mikeljon P

2017-06-10

For decades, bacteriophages (phages) have been used for Brucella species identification in the diagnosis and epidemiology of brucellosis. Traditional Brucella phage typing is a multi-day procedure including the isolation of a pure culture, a step that can take up to three weeks. In this study, we focused on the use of brucellaphages for sensitive detection of the pathogen in clinical and other complex samples, and developed an indirect method of Brucella detection using real-time quantitative PCR monitoring of brucellaphage DNA amplification via replication on live Brucella cells. This assay allowed the detection of single bacteria (down to 1 colony-forming unit per milliliter) within 72 h without DNA extraction and purification steps. The technique was equally efficient with Brucella abortus pure culture and with mixed cultures of B . abortus and α-proteobacterial near neighbors that can be misidentified as Brucella spp., Ochrobactrum anthropi and Afipia felis . The addition of a simple short sample preparation step enabled the indirect phage-based detection of B . abortus in spiked blood, with the same high sensitivity. This indirect phage-based detection assay enables the rapid and sensitive detection of live B . abortus in mixed cultures and in blood samples, and can potentially be applied for detection in other clinical samples and other complex sample types.

2015-01-01

The aim of this study is to explore the relations of workplace culture on nursing-sensitive organizational factors. The need for standardized and valid measures for nursing-sensitive organizational outcomes has already been recognized in the literature. A cross-sectional questionnaire survey of 21 inpatient acute care units in 9 organizations at the municipal primary healthcare level was conducted. Participants included licensed practical nurses, registered nurses, and nurse managers. Workplace culture, especially the overarching factor of stress, correlated with the use of supplemental nursing staff and patients' length of stay. It is essential to find and test workplace-sensitive indicators so that managers will have a wider range of methods to plan and evaluate nursing outcomes.

(Please see www.Toolsfortalking.co.uk for an easy read summary of the project.) The Tools for Talking are a set of resources that were developed through collaboration between Black, Asian and minority ethnic people with learning disabilities and researchers at the University of Birmingham. The resources were designed to be used by people with learning disabilities and service providers to facilitate culturally-sensitive communication and information sharing, service planning and delivery. They comprise illustrative videos and exploratory activities relating to five topics, namely, culture, activities, support from staff, important people, choices and independence. These topics emerged as important to people with learning disabilities during the 'Access to Social Care-Learning Disabilities' (ASC-LD) study which involved interviews with 32 adults with learning disabilities from Black, Asian and minority ethnic communities. The results of the ASC-LD study were used to develop a set of draft resources which were then co-developed through collaboration with people with learning disabilities and service providers. A 'Partnership event' was convened to involve stakeholders in the development of the resources. This paper describes the refinement of these materials by people with learning disabilities from Black, Asian and minority ethnic backgrounds in cooperation with a range of other stakeholders. Background Black, Asian and minority ethnic people with learning disabilities face inequities in health and social care provision. Lower levels of service uptake and satisfaction with services have been reported, however, this is largely based on the views of carers. The 'Access to Social Care: Learning Disabilities (ASC-LD)' study sought to explore the views and experiences of social support services among adults with learning disabilities from Black, Asian and minority ethnic communities. Interviews with 32 Black, Asian and minority ethnic adults with learning disabilities

The use of vermicompost (humified material) for treating wastewaters, remediating polluted soils, improving agricultural productivity, protecting crop production, and developing sensitive analytical methods is reviewed here, covering the past 17 years. The main advantages of vermicompost, considering all applications covered in this paper, comprise (i) easy acquisition, (ii) low costs, (iii) structural, chemical, and biological characteristics responsible for exceptional adsorptive capacities as well as pollutant degradation, and (iv) the promotion of biocontrol. Specifically, for wastewater decontamination, a considerable number of works have verified the adsorption of toxic metals, but the application of vermicompost is still scarce for the retention of organic compounds. Problems related to the final disposal of enriched vermicompost (after treatment steps) are often found, in spite of some successful destinations such as organic fertilizer. For decontaminating soils, the use of vermicompost is quite scarce, mainly for inorganic pollutants. In agricultural productivity and biocontrol, vermicompost imparts remarkable benefits regarding soil aggregation, plant nutrition, and the development of beneficial microorganisms against phytopathogens. Finally, the use of vermicompost in sensitive analytical methods for quantifying toxic metals is the newest application of this adsorbent.

Development of high Sensitivity Materials for Applications in Magneto-Mechanical Torque Sensor

Energy Technology Data Exchange (ETDEWEB)

Shen, Yuping [Iowa State Univ., Ames, IA (United States)

2003-01-01

The Matteucci effect, which mainly manifests itself as the change of magnetization of a material with torsional stress, is currently of great technological interest because of the search for magnetic torque sensors. Magnetic torque sensors are important to future improvements of automobiles and industrial robots. It is well known that the magnetic state of a material depends on both the external magnetic field and external stress which causes strain and change in magnetization of the material. The former phenomenon has been well understood in both theory and application. However, the magnetic state dependence of stress is not adequately understood and the experimental data is of limited extent. In this project, the Matteucci effect in iron, cobalt, nickel and permalloy rods has been documented when they were in magnetic remanence status along the axis and nickel ring when they were in remanence status along the circumference. The effect of annealing on the magnetomechanical effect in nickel and the temperature dependence of the magnetomechanical sensitivity has also been examined. Factors related to the sensitivity at equilibrium condition have been theoretically developed. it is found in the experiments that the mechanism of magnetic domain wall movement plays an important role rather than the domain rotation. A higher sensitivity was found by domain wall movement mechanism than that by domain rotation mechanism. However, the domain wall movement will result in more hysteresis than domain wall rotation. The dynamic process of Matteucci effect of iron, cobalt, permally, especially as-fabricated and annealed nickel rods have been examined. A tentative explanation for the difference of these in terms of magnetic domain configuration and domain wall movement was given. As a result, another method of configuring and processing magnetic domains to get a linear magnetomechanical response other than that suggested by Garshelis, which was the basic method before the

Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

A fast and highly sensitive blood culture PCR method for clinical detection of Salmonella enterica serovar Typhi

Directory of Open Access Journals (Sweden)

Zhou Liqing

2010-04-01

Full Text Available Abstract Background Salmonella Typhi causes an estimated 21 million new cases of typhoid fever and 216,000 deaths every year. Blood culture is currently the gold standard for diagnosis of typhoid fever, but it is time-consuming and takes several days for isolation and identification of causative organisms. It is then too late to initiate proper antibiotic therapy. Serological tests have very low sensitivity and specificity, and no practical value in endemic areas. As early diagnosis of the disease and prompt treatment are essential for optimal management, especially in children, a rapid sensitive detection method for typhoid fever is urgently needed. Although PCR is sensitive and rapid, initial research indicated similar sensitivity to blood culture and lower specificity. We developed a fast and highly sensitive blood culture PCR method for detection of Salmonella Typhi, allowing same-day initiation of treatment after accurate diagnosis of typhoid. Methods An ox bile tryptone soy broth was optimized for blood culture, which allows the complete lysis of blood cells to release intracellular bacteria without inhibiting the growth of Salmonella Typhi. Using the optimised broth Salmonella Typhi bacteria in artificial blood samples were enriched in blood culture and then detected by a PCR targeting the fliC-d gene of Salmonella Typhi. Results Tests demonstrated that 2.4% ox bile in blood culture not only lyzes blood cells completely within 1.5 hours so that the intracellular bacteria could be released, but also has no inhibiting effect on the growth of Salmonella Typhi. Three hour enrichment of Salmonella Typhi in tryptone soya broth containing 2.4% ox bile could increase the bacterial number from 0.75 CFU per millilitre of blood which is similar to clinical typhoid samples to the level which regular PCR can detect. The whole blood culture PCR assay takes less than 8 hours to complete rather than several days for conventional blood culture

This review introduces the concept of culture-sensitive health communication. The basic premise is that congruency between the recipient's cultural characteristics and the respective message will increase the communication's effectiveness. Culture-sensitive health communication is therefore defined as the deliberate and evidence-informed adaptation of health communication to the recipients' cultural background in order to increase knowledge and improve preparation for medical decision making and to enhance the persuasiveness of messages in health promotion. To achieve effective health communication in varying cultural contexts, an empirically and theoretically based understanding of culture will be indispensable. We therefore define culture, discuss which evolutionary and structural factors contribute to the development of cultural diversity, and examine how differences are conceptualized as scientific constructs in current models of cultural differences. In addition, we will explicate the implications of cultural differences for psychological theorizing, because common constructs of health behavior theories and decision making, such as attitudes or risk perception, are subject to cultural variation. In terms of communication, we will review both communication strategies and channels that are used to disseminate health messages, and we will discuss the implications of cultural differences for their effectiveness. Finally, we propose an agenda both for science and for practice to advance and apply the evidence base for culture-sensitive health communication. This calls for more interdisciplinary research between science and practice but also between scientific disciplines and between basic and applied research. © The Author(s) 2015.

Endothelin-1 (ET-1) is recognized as being involved in the pathophysiology of cerebrovascular diseases. Using organ culture as a model for possible pathological changes we studied changes in ET(A) and ETB receptor function using a sensitive in vitro method. We observed an up-regulation of the ET......(B) receptor and an amazingly increased sensitivity to ET-1 by 3 log units in pEC50; pEC50(fresh) was 8.7 +/- 0.1, and pEC50(cultured) was 11.7 +/- 0.3. pA2 for FR139317 in the fresh vessel was 7.0 +/- 0.2 whereas it could not be obtained for the cultured vessel, indicating a possible cross-talk between the ET......(A) and ET(B) receptors. The increased sensitivity to ET-1 could also take place during cerebrovascular disease such as stroke or haemorrhage rendering the vessels considerably more sensitive to ET-1....

Application of a nitrocellulose immunoassay for quantitation of proteins secreted in cultured media

International Nuclear Information System (INIS)

LaDuca, F.M.; Dang, C.V.; Bell, W.R.

1986-01-01

A macro immunoassay was developed to quantitate proteins (antigens) secreted in the culture media of primary rat hepatocytes. Dilutions of protein standards and undiluted spent culture media were applied to numbered sheets of nitrocellulose (NC) paper by vacuum filtration (in volumes up to 1 ml) through a specially designed macrofiltration apparatus constructed of plexiglas. Sequential incubation of the NC with bovine serum albumin blocking buffer, monospecific antibody, and 125 I Protein A enabled quantitation of protein concentration by determination of NC bound radioactivity. Linear and reproducible standard curves were obtained with fibrinogen, albumin, transferrin, and haptoglobin. A high degree of coefficient of correlation between radioactivity (cmp) and protein concentration was found. Intra- and inter-test reproducibility was excellent. By using monospecific antibodies, single proteins (i.e., fibrinogen), as low as 32 ng/ml, could be quantified in heterogeneous protein mixtures and in spent culture media. The assay was sensitive to the difference of fibrinogen secretion under nonstimulatory (serum-free hormonally define medium, SFHD) and stimulatory (SFHD plus hydrocortisone) culture conditions. The procedure and techniques described are applicable to the quantitation of any protein in a suitable buffer

2017-07-01

As foreigners live in and visit Turkey for various reasons, it is essential to provide culturally appropriate health care. This study was conducted to determine the relationship between cultural sensitivity and assertiveness in university nursing students. This descriptive, cross-sectional study was conducted at two universities in the cities of Kilis and Elazığ, Turkey. The study sample consisted of 444 nursing students. Data collection tools included a questionnaire about participant sociodemographic characteristics, Chen and Starosta's Intercultural Sensitivity Scale, and the Rathus Assertiveness Scale. The mean age of participants was 21.09 years. Most students (71.6%) were female and 34.7% of the students stayed at the hostel. Of the students, 44.4%, 27.5%, and 28.2% attended were the second-, third-, and fourth-year students, respectively. Participants were asked about problems related to caring for patients who speak different languages. The mean score for the Intercultural Sensitivity Scale was 89.42 ± 13.55 and the total score for all students for the Assertiveness Scale was 112.64 ± 15.61. We identified a positive relationship between total scores for the Intercultural Sensitivity Scale and the Assertiveness Scale ( p assertiveness and year of nursing education and want to work overseas. Nursing students at both schools had a moderate level of cultural sensitivity and assertiveness. It has been determined that as assertiveness level of the students increased, intercultural sensitivity of them also increased. Consequently, it is concluded that training as assertive and self-confident individuals during the nursing education of students has a contribution to making patient-specific and culture-sensitive care.

Science.gov (United States)

Kurtz, S M; Adams, C L

2009-08-01

In the practise of veterinary medicine and global public health, communication skill is as critical as clinical reasoning and an extensive knowledge base. Effective communication skills and cross-cultural sensitivity are essential across the board for interdisciplinary, international, and local veterinary medicine. This paper offers an evidence-based, three-part framework for developing and sustaining curricula that enhance communication skills and cross-cultural sensitivity so that students are better prepared to practise veterinary medicine in an evolving world. These curricula may well also serve as a conduit for encouraging more veterinary graduates to choose global public health as a career path.

Investigation, development and application of optimal output feedback theory. Vol. 4: Measures of eigenvalue/eigenvector sensitivity to system parameters and unmodeled dynamics

Science.gov (United States)

Halyo, Nesim

1987-01-01

Some measures of eigenvalue and eigenvector sensitivity applicable to both continuous and discrete linear systems are developed and investigated. An infinite series representation is developed for the eigenvalues and eigenvectors of a system. The coefficients of the series are coupled, but can be obtained recursively using a nonlinear coupled vector difference equation. A new sensitivity measure is developed by considering the effects of unmodeled dynamics. It is shown that the sensitivity is high when any unmodeled eigenvalue is near a modeled eigenvalue. Using a simple example where the sensor dynamics have been neglected, it is shown that high feedback gains produce high eigenvalue/eigenvector sensitivity. The smallest singular value of the return difference is shown not to reflect eigenvalue sensitivity since it increases with the feedback gains. Using an upper bound obtained from the infinite series, a procedure to evaluate whether the sensitivity to parameter variations is within given acceptable bounds is developed and demonstrated by an example.

Suk, Min Hyun; Oh, Won Oak; Im, Yeo Jin; Cho, Hun Ha

2015-09-01

This study examined the mediating effect of school nurses' self efficacy, which is one of the significant cognitive factors influencing cultural sensitivity, on the mutual relationships between multicultural attitude and cultural sensitivity in Korean elementary schools. A cross-sectional descriptive survey design was used. Participants were 157 school nurses in elementary schools located in Gyeonggi-do, South Korea. The survey instruments included Teacher Multicultural Attitude Survey, Teacher Efficacy Scale, and Multicultural Sensitivity Scale. Data were analyzed using three regression equations to test the mediation model. The mean score of the school nurses' cultural sensitivity was relatively low. A positive correlation among multicultural attitude, self efficacy, and cultural sensitivity was noted. Self efficacy of school nurses showed a significant mediating effect on the relationships between multicultural attitude and cultural sensitivity. Given the meaningful influence of positive multicultural attitude on cultural sensitivity and significant mediator effect of self efficacy as a school nurse between the two variables, the strategies to cultivate a positive multicultural attitude and enhance school nurses' self efficacy in their unique role should be considered in a training program. School nurses' health care services will benefit from the improvement of cultural sensitivity toward young children from multicultural families. Copyright © 2015. Published by Elsevier B.V.

Synthesis strategy: building a culturally sensitive mid-range theory of risk perception using literary, quantitative, and qualitative methods.

Science.gov (United States)

Siaki, Leilani A; Loescher, Lois J; Trego, Lori L

2013-03-01

This article presents a discussion of development of a mid-range theory of risk perception. Unhealthy behaviours contribute to the development of health inequalities worldwide. The link between perceived risk and successful health behaviour change is inconclusive, particularly in vulnerable populations. This may be attributed to inattention to culture. The synthesis strategy of theory building guided the process using three methods: (1) a systematic review of literature published between 2000-2011 targeting perceived risk in vulnerable populations; (2) qualitative and (3) quantitative data from a study of Samoan Pacific Islanders at high risk of cardiovascular disease and diabetes. Main concepts of this theory include risk attention, appraisal processes, cognition, and affect. Overarching these concepts is health-world view: cultural ways of knowing, beliefs, values, images, and ideas. This theory proposes the following: (1) risk attention varies based on knowledge of the health risk in the context of health-world views; (2) risk appraisals are influenced by affect, health-world views, cultural customs, and protocols that intersect with the health risk; (3) strength of cultural beliefs, values, and images (cultural identity) mediate risk attention and risk appraisal influencing the likelihood that persons will engage in health-promoting behaviours that may contradict cultural customs/protocols. Interventions guided by a culturally sensitive mid-range theory may improve behaviour-related health inequalities in vulnerable populations. The synthesis strategy is an intensive process for developing a culturally sensitive mid-range theory. Testing of the theory will ascertain its usefulness for reducing health inequalities in vulnerable groups. © 2012 Blackwell Publishing Ltd.

Cultural relativism: maintenance of genomic imprints in pluripotent stem cell culture systems.

Science.gov (United States)

Greenberg, Maxim Vc; Bourc'his, Déborah

2015-04-01

Pluripotent stem cells (PSCs) in culture have become a widely used model for studying events occurring during mammalian development; they also present an exciting avenue for therapeutics. However, compared to their in vivo counterparts, cultured PSC derivatives have unique properties, and it is well established that their epigenome is sensitive to medium composition. Here we review the specific effects on genomic imprints in various PSC types and culture systems. Imprinted gene regulation is developmentally important, and imprinting defects have been associated with several human diseases. Therefore, imprint abnormalities in PSCs may have considerable consequences for downstream applications. Copyright © 2015 Elsevier Ltd. All rights reserved.

Noman, F.; Ahmed, A.

2008-01-01

The aim of this study was to evaluate the error in interpreting antimicrobial sensitivity by direct method when compared to standard method and find out if specific antibiotic-organism combination had more discrepancies. All blood culture samples received at Microbiology Laboratory from 1st July 2006 to 31st August 2006 were ncluded in the study. All samples were inoculated in automated blood culture system BACTEC 9240 which contained enriched Soybean-Casein Digest broth with CO/sub 2/. Once positive, bottles were removed from system; gram staining of the positive broths was done. Susceptibility test was performed from positive broth, on MHA (Mueller-Hinton Agar), with antibiotics panel according to gram stain result. All positive broths were also sub-cultured on blood agar, chocolate agar and McConkey agar for only gram-negative rods. Next day, the zone sizes of all antibiotics were recorded using measuring scale and at the same time susceptibility test was repeated from isolated colonies from subcultures, with inoculums prepared of McFarland 0.5 standard 0.2 Staphylococcus aureus (ATCC 29213); E.coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853) were included as quality control strain. Zone sizes were interpreted as sensitive (S), resistant (R) and intermediate (I) according to CLSI recommendation. Two results were compared and recorded. Out of a total 1083 combinations, zone diameters by standard method were either equal or greater than direct zone diameter (never smaller). Most of the discrepancies were in b-lactam/b-lactamase combinations and aminoglycosides. While reporting these groups of antibiotics with direct sensitivity test, one should be cautious. These are the major antibiotic used for life-threatening infections. In case of being heavy/lighter standard inoculums or marginal zones, repeating with standard method should be preferred to minimize the chances of error. (author)

A fast and systematic procedure to develop dynamic models of bioprocesses: application to microalgae cultures

J. Mailier

2010-09-01

Full Text Available The purpose of this paper is to report on the development of a procedure for inferring black-box, yet biologically interpretable, dynamic models of bioprocesses based on sets of measurements of a few external components (biomass, substrates, and products of interest. The procedure has three main steps: (a the determination of the number of macroscopic biological reactions linking the measured components; (b the estimation of a first reaction scheme, which has interesting mathematical properties, but might lack a biological interpretation; and (c the "projection" (or transformation of this reaction scheme onto a biologically-consistent scheme. The advantage of the method is that it allows the fast prototyping of models for the culture of microorganisms that are not well documented. The good performance of the third step of the method is demonstrated by application to an example of microalgal culture.

Many of the approximately 15 million people with a migration background living in Germany (19% of the population) are inadequately reached by existing healthcare provision. In the literature, the necessity for cultural adaptation of information material for patients with a migration background is often cited as a measure for improving healthcare.In this study, culturally sensitive information material will be developed and evaluated for patients with a migration background and depression or chronic low back pain. In this respect, it will be examined whether culturally sensitive information material is judged as more useful by the patients than standard translated patient information without cultural adaptation. The implementation and evaluation of culturally sensitive patient information material will occur in the framework of a double-blind randomized controlled parallel-group study in four study centres in Germany. Primary care patients with a Turkish, Polish, Russian or Italian migration background with a diagnosis of depressive disorder or chronic low back pain will be included and randomly allocated to the intervention group or the control group. In the intervention group, culturally sensitive patient information will be handed to the patient at the end of the physician consultation, while in the control group, standard translated patient information material will be provided. The patients will be surveyed by means of questionnaires following the consultation as well as after 8 weeks and 6 months. In addition to the primary outcome (subjective usefulness), several patient- and physician-rated secondary outcomes will be considered. The study will provide an empirical answer to the question of whether persons with a migration background perceive culturally sensitive patient information material as more useful than translated information material without cultural adaptation.

2011-12-01

Full Text Available The aim of this paper is to discuss a particular view on cultural psychology focusedon “lived experience” and “vital geography” terms. It is provided sometheoretical principles and applications of this perspective. According to this view,human development is the result of participation in educational practices throughwhich people appropriate the “signs”, “cultural technology” or explicit and implicitforms of shared life. It is postulated two assumptions and three features.The assumptions are: the lived experienced should be studied in the context orsituation where it is expressed and constructed, and the “cultural diet” is thefood of our psyche (our memories, fears, perceptions, feelings, thoughts. The featuresremind us to consider the human experience as the unit of analysis, bothsituated and distributed, and finally, as a product of participation in particularvital geographies. Applications are outlined in the field of clinical psychology andrehabilitation, socioeducative field and in the field of social psychology of organizations,as examples of practices according to a culturally oriented psychology.Finally, it is emphasized the need to take into account the subjective, social andpolitical sides of culture in order to develop an ecological understanding of mindand human behavior.

The development of the Qatar National Historic Environment Record (QNHER) by the Qatar Museums Authority and the University of Birmingham in 2008 was based on a customised, bilingual Access database and ArcGIS. While both platforms are stable and well supported, neither was designed for the documentation and retrieval of cultural heritage data. As a result it was decided to develop a custom application using Open Source code. The core module of this application is now completed and is orientated towards the storage and retrieval of geospatial heritage data for the curation of heritage assets. Based on MIDAS Heritage data standards and regionally relevant thesauri, it is a truly bilingual system. Significant attention has been paid to the user interface, which is userfriendly and intuitive. Based on a suite of web services and accessed through a web browser, the system makes full use of internet resources such as Google Maps and Bing Maps. The application avoids long term vendor ''tie-ins'' and as a fully integrated data management system, is now an important tool for both cultural resource managers and heritage researchers in Qatar.

Haloxyfop mode of action in liquid cultures of proso millet: An analysis of haloxyfop sensitivity changes during growth

International Nuclear Information System (INIS)

Irzyk, G.P.

1989-01-01

Haloxyfop is a grass-selective herbicide that inhibits acetyl-CoA carboxylase in species that are not tolerant to the herbicide. Liquid cultures of proso millet (Panicum miliaceum) cells treated with haloxyfop at different phases of growth exhibited different levels of sensitivity to the herbicide. Treatment of 1-d cultures with 1 μM haloxyfop completely inhibited growth within 48 h. In contrast, 1 mM haloxyfop was required to elicit a similar response in 4-, 7-, or 10-d cultures. Calculated IC 50 values indicated a 300-fold decrease in haloxyfop sensitivity during the period from 1 to 4 d. This period of growth coincided with the greatest increase in cell number during culture growth and suggested that dividing cells are most sensitive to haloxyfop. Uptake and metabolism of 14 C-haloxyfop in 1-d and 4-d cultures were compared. In both cultures, amounts of radiolabel uptake were similar. Almost all radioactivity extracted from 1- and 4-d cells was present as the parent compound. These results suggested that the sensitivity change was related to other factors. Acetyl-CoA carboxylase activity of proso millet cells, measured in vitro by the acetyl-CoA-dependent incorporation of 14 C-bicarbonate into an acid-stable product, was essentially constant during culture growth. Micromolar concentrations of haloxyfop significantly inhibited acetyl-CoA carboxylase activity from both sensitive and insensitive cultures. Thus, the change in the sensitivity of cultures to haloxyfop was not correlated with changes in acetyl-CoA carboxylase abundance, activity, or sensitivity to haloxyfop during culture growth. In vivo incorporation of 14 C-acetate into lipids was decreased by 1 μM haloxyfop in both 1-d and 4-d cultures at the earliest sampling times but the amount of inhibition was significantly greater in the sensitive cultures

Fifty patients who fulfilled the clinical criteria of having Typhoid Fever. The data of all the patients was documented, and they were submitted to the Typhi Dot and Blood Culture tests, apart from other routine investigations. Out of the total 50 patients, 47(94%) had their Blood Culture positive for Typhoid bacillus, while in 49 (98%) the Typhi Dot test was positive. Two patients which were found positive on Typhi dot test, gave negative results on Blood Culture. One patient with the signs and symptoms of Typhoid Fever was found neither positive on Typhi Dot test nor upon Blood Culture. There was no significant difference between the results of Blood Culture and Typhi Dot test in the diagnosis of Typhoid Fever. However, Typhi Dot has the advantages of being less expensive and quicker in giving results with excellent sensitivity. (author)

Ensuring cultural sensitivity for Muslim patients in the Australian ICU: considerations for care.

Science.gov (United States)

Bloomer, Melissa J; Al-Mutair, Abbas

2013-11-01

Australia is a diverse and multicultural nation, made up of a population with a predominant Christian faith. Islam, the second largest religion in the world, has demonstrated significant growth in Australia in the last decade. Coming from various countries of origin and cultural backgrounds, Muslim beliefs can range from what is considered 'traditional' to very 'liberal'. It is neither possible nor practical for every intensive care clinician to have an intimate understanding of Islam and Muslim practices, and cultural variations amongst Muslims will mean that not all beliefs/practices will be applicable to all Muslims. However, being open and flexible in the way that care is provided and respectful of the needs of Muslim patients and their families is essential to providing culturally sensitive care. This discussion paper aims to describe the Islamic faith in terms of Islamic teachings, beliefs and common practices, considering how this impacts upon the perception of illness, the family unit and how it functions, decision-making and care preferences, particularly at the end of life in the intensive care unit.

Developing written information for cancer survivors from culturally and linguistically diverse backgrounds: Lessons learnt

Directory of Open Access Journals (Sweden)

Georgina Wiley

2018-01-01

Full Text Available Australia is a multicultural nation with a large migrant population. Migrants with cancer report inferior quality of life and the need for more information in their own language. This paper describes lessons learnt from developing culturally appropriate written information resources with and for Arabic, Italian, and Vietnamese cancer survivors and carers. The information needs of survivors from these language groups as well as guidelines for the development of written resources for culturally diverse populations were identified through literature review. Community consultation was undertaken with focus groups. The content was developed and tested with health professionals who spoke the appropriate language and focus group participants, ensuring relevance and appropriateness. Resource design and dissemination were informed through community consultation. A number of key tasks for developing resources were identified as follows: (1 community engagement and consultation; (2 culturally sensitive data collection; (3 focus group facilitators (recruitment and training; (4 content development; (5 translation and review process; (6 design; and (7 sustainability. This project reinforced literature review findings on the importance of cultural sensitivity in the development of resources. Engaging with community groups and incorporating culturally appropriate recruitment strategies optimises recruitment to focus groups and facilitates content development. Stakeholders and lay persons from the intended ethnic-minority communities should be involved in the development and formative evaluation of resources to ensure appropriateness and relevance and in the dissemination strategy to optimize penetration. We believe the lessons we have learnt will be relevant to any group intending to develop health information for culturally and linguistic diverse groups.

2014-01-01

Current fundamental investigations of human biology and the development of therapeutic drugs, commonly rely on two-dimensional (2D) monolayer cell culture systems. However, 2D cell culture systems do not accurately recapitulate the structure, function, physiology of living tissues, as well as highly complex and dynamic three-dimensional (3D) environments in vivo. The microfluidic technology can provide micro-scale complex structures and well-controlled parameters to mimic the in vivo environment of cells. The combination of microfluidic technology with 3D cell culture offers great potential for in vivo-like tissue-based applications, such as the emerging organ-on-a-chip system. This article will review recent advances in microfluidic technology for 3D cell culture and their biological applications. PMID:22793034

Prostate cancer (PrCA) is the most common cancer affecting men in the United States, and African American men have the highest incidence among men in the United States. Little is known about the PrCA-related educational materials being provided to patients in health-care settings. Content, readability, and cultural sensitivity of materials available in providers' practices in South Carolina were examined. A total of 44 educational materials about PrCA and associated sexual dysfunction was collected from 16 general and specialty practices. The content of the materials was coded, and cultural sensitivity was assessed using the Cultural Sensitivity Assessment Tool. Flesch Reading Ease, Flesch-Kincaid Grade Level, and the Simple Measure of Gobbledygook were used to assess readability. Communication with health-care providers (52.3%), side effects of PrCA treatment (40.9%), sexual dysfunction and its treatment (38.6%), and treatment options (34.1%) were frequently presented. All materials had acceptable cultural sensitivity scores; however, 2.3% and 15.9% of materials demonstrated unacceptable cultural sensitivity regarding format and visual messages, respectively. Readability of the materials varied. More than half of the materials were written above a high-school reading level. PrCA-related materials available in health-care practices may not meet patients' needs regarding content, cultural sensitivity, and readability. A wide range of educational materials that address various aspects of PrCA, including treatment options and side effects, should be presented in plain language and be culturally sensitive.

Greek Immigrants in Australia: Implications for Culturally Sensitive Practice.

Georgiades, Savvas Daniel

2015-10-01

This exploratory research examined adjustment challenges, resiliencies, attitudes, emotional health, economic stability, criminal involvement, victimization and service experiences, and some cultural propensities of Greek Immigrants (GIs) in Australia using a convenient multi-generational sample (n = 123; response rate = .5). Data were collected via surveys, telephone, and personal-interviews in four major Australian cities. Among other things, the study revealed that Greek identity and cultural customs are often significant to first generation GIs. Adjustment challenges upon entry include primarily language, housing, and transportation difficulties, nostalgia for relatives and the motherland, unfamiliarity with socio-cultural systems, unemployment, money challenges, and lack of friendships. Christian faith, the extended family, family values and traditions, cultural pride for ancient Greek achievements, and a hard 'work ethic' are notable resiliencies that support GIs in their struggles and solidify their pursuit for happiness and success. Financial concerns, aging, and nostalgia for relatives and the motherland were the primary causes of socio-emotional instability. Attitudinal differences in the respondents based on age, gender, and socio-economic status, cross-cultural comparisons, and recommendations for culturally-sensitive practice with GIs are analyzed and methodological limitations illuminated. Future research needs in the field are also highlighted.

The limitations of the agar suspension culture method for primary culturing of human tumor cells prompted development of a monolayer system optimized for cell adhesion and growth. This method grew 83% of fresh human tumor cell biopsy specimens, cultured and not contaminated, from a heterogeneous group of 396 tumors including lung cancer (93 of 114, 82%); melanoma (54 of 72, 75%); sarcoma (46 of 59, 78%); breast cancer (35 of 39, 90%); ovarian cancer (16 of 21, 76%); and a miscellaneous group consisting of gastrointestinal, genitourinary, mesothelioma, and unknown primaries (78 of 91, 86%). Cell growth was characterized morphologically with Papanicolaoustained coverslip cultures and cytogenetically with Giemsastained metaphase spreads. Morphological features such as nuclear pleomorphism, chromatin condensation, basophilic cytoplasm, and melanin pigmentation were routinely seen. Aneuploid metaphases were seen in 90% of evaluable cultures, with 15 of 28 showing 70% or more aneuploid metaphases. Colony-forming efficiency ranged between 0.01 and 1% of viable tumor cells, with a median efficiency of 0.2%. This culture system uses a low inoculum of 25,000 viable cells per well which permitted chemosensitivity testing of nine drugs at four doses in duplicate from 2.2 X 10(6) viable tumor cells and radiation sensitivity testing at five doses in quadruplicate from 0.6 X 10(6) cells. Cultures were analyzed for survival by computerized image analysis of crystal violet-stained cells. Drug sensitivity studies showed variability in sensitivity and in survival curve shape with exponential cell killing for cisplatin, Adriamycin, and etoposide, and shouldered survival curves for 5-fluorouracil frequently seen. Radiation sensitivity studies also showed variability in both sensitivity and survival curve shape. Many cultures showed exponential cell killing, although others had shouldered survival curves

Bloodstream infection (BSI) and sepsis are rising in incidence throughout the developed world. The spread of multi-drug resistant organisms presents increasing challenges to treatment. Surviving BSI is dependent on rapid and accurate identification of causal organisms, and timely application of appropriate antibiotics. Current culture-based methods used to detect and identify agents of BSI are often too slow to impact early therapy and may fail to detect relevant organisms in many positive cases. Existing methods for direct molecular detection of microbial DNA in blood are limited in either sensitivity (likely the result of small sample volumes) or in breadth of coverage, often because the PCR primers and probes used target only a few specific pathogens. There is a clear unmet need for a sensitive molecular assay capable of identifying the diverse bacteria and yeast associated with BSI directly from uncultured whole blood samples. We have developed a method of extracting DNA from larger volumes of whole blood (5 ml per sample), amplifying multiple widely conserved bacterial and fungal genes using a mismatch- and background-tolerant PCR chemistry, and identifying hundreds of diverse organisms from the amplified fragments on the basis of species-specific genetic signatures using electrospray ionization mass spectrometry (PCR/ESI-MS). We describe the analytical characteristics of the IRIDICA BAC BSI Assay and compare its pre-clinical performance to current standard-of-care methods in a collection of prospectively collected blood specimens from patients with symptoms of sepsis. The assay generated matching results in 80% of culture-positive cases (86% when common contaminants were excluded from the analysis), and twice the total number of positive detections. The described method is capable of providing organism identifications directly from uncultured blood in less than 8 hours. Disclaimer: The IRIDICA BAC BSI Assay is not available in the United States.

Midwifery educators and regulators in Canada have begun to address diversity, equity, and inclusion in admission processes and program curricula. Populations served by midwives value internationally educated midwives from their countries of origin. The International Midwifery Pre-Registration Program at Ryerson University in Toronto, Ontario, provides assessment, midwifery workplace orientation, and accelerated education for internationally educated midwives on behalf of the regulatory College of Midwives of Ontario. Between 2003 and 2015, midwives from 41 countries participated in the bridging program, and 214 (80%) successfully completed the program and qualified for licensure. Of these 214 graduates, 100% passed the Canadian Midwifery Registration Examination and 193 (90%) were employed full time as midwives within 4 months of graduation. The program curriculum enables the integration of these midwives into health care workplaces utilizing innovative approaches to assessment and competency enhancement. Critical to the bridging process are simulation-based practices to develop effective psychomotor learning, virtual and real primary care community placements, and coaching in empathetic, client-centered communication. Cultural sensitivity is embedded into the multiple assessment and learning modalities, and addresses relevant barriers faced by immigrant midwives in the workplace. Findings from the 13 years of the program may be applicable to increase diversity in other North American midwifery settings. This article describes the process, content, outcomes, and findings of the program. Midwifery educators and regulators may consider the utility of these approaches for their settings. © 2016 by the American College of Nurse-Midwives.

Patients with low literacy, low numeracy, and/or linguistic needs can experience challenges understanding diabetes information and applying concepts to their self-management. The authors designed a toolkit of education materials that are sensitive to patients' literacy and numeracy levels, language preferences, and cultural norms and that encourage shared goal setting to improve diabetes self-management and health outcomes. The Partnership to Improve Diabetes Education (PRIDE) toolkit was developed to facilitate diabetes self-management education and support. The PRIDE toolkit includes a comprehensive set of 30 interactive education modules in English and Spanish to support diabetes self-management activities. The toolkit builds upon the authors' previously validated Diabetes Literacy and Numeracy Education Toolkit (DLNET) by adding a focus on shared goal setting, addressing the needs of Spanish-speaking patients, and including a broader range of diabetes management topics. Each PRIDE module was evaluated using the Suitability Assessment of Materials (SAM) instrument to determine the material's cultural appropriateness and its sensitivity to the needs of patients with low literacy and low numeracy. Reading grade level was also assessed using the Automated Readability Index (ARI), Coleman-Liau, Flesch-Kincaid, Fry, and SMOG formulas. The average reading grade level of the materials was 5.3 (SD 1.0), with a mean SAM of 91.2 (SD 5.4). All of the 30 modules received a "superior" score (SAM >70%) when evaluated by 2 independent raters. The PRIDE toolkit modules can be used by all members of a multidisciplinary team to assist patients with low literacy and low numeracy in managing their diabetes. © 2015 The Author(s).

Early detection of developmental delay is essential to initiate early intervention. The Ages and Stages Questionnaires (ASQ) correlate well with physician's assessment and have high predictive value. No such tool exists in Arabic. Translate and test the applicability and reliability of Arabic translated Ages and Stages Questionnaires (A-ASQ) in an Arabic speaking population. 733 healthy children were assessed. ASQ-II for 10 age groups (4-60 months) were translated to Arabic, back translations and cultural adaptation were performed. Test-retest reliability and internal consistency were evaluated using Pearson Correlation Coefficient (CC) and Cronbach's alpha (Cα). Mean scores per domain were compared to US normative scores using t-test. A-ASQ, after culturally relevant adaptations, was easily administered for 4-36 months age groups but not for 4-5 year old due to numerous cultural differences in the later. For the 4-36 month age groups Pearson CC ranged from 0.345 to 0.833. The internal consistency coefficients Cα scores ranged from 0.111 to 0.816. Significant differences were found in the mean domain scores of all age groups between Lebanese and US normative sample (p-value internal consistency and reliability in the younger age groups. It proved to be culturally sensitive, which should be taken into consideration when adapting such tool to non-western populations. Copyright © 2013 European Paediatric Neurology Society.

Applications requiring detection of small visual contrast require high sensitivity. Event cameras can provide higher dynamic range (DR) and reduce data rate and latency, but most existing event cameras have limited sensitivity. This paper presents the results of a 180-nm Towerjazz CIS process vision sensor called SDAVIS192. It outputs temporal contrast dynamic vision sensor (DVS) events and conventional active pixel sensor frames. The SDAVIS192 improves on previous DAVIS sensors with higher sensitivity for temporal contrast. The temporal contrast thresholds can be set down to 1% for negative changes in logarithmic intensity (OFF events) and down to 3.5% for positive changes (ON events). The achievement is possible through the adoption of an in-pixel preamplification stage. This preamplifier reduces the effective intrascene DR of the sensor (70 dB for OFF and 50 dB for ON), but an automated operating region control allows up to at least 110-dB DR for OFF events. A second contribution of this paper is the development of characterization methodology for measuring DVS event detection thresholds by incorporating a measure of signal-to-noise ratio (SNR). At average SNR of 30 dB, the DVS temporal contrast threshold fixed pattern noise is measured to be 0.3%-0.8% temporal contrast. Results comparing monochrome and RGBW color filter array DVS events are presented. The higher sensitivity of SDAVIS192 make this sensor potentially useful for calcium imaging, as shown in a recording from cultured neurons expressing calcium sensitive green fluorescent protein GCaMP6f.

Cultures of simulations vs. cultures of calculations? The development of simulation practices in meteorology and astrophysics

Science.gov (United States)

Sundberg, Mikaela

While the distinction between theory and experiment is often used to discuss the place of simulation from a philosophical viewpoint, other distinctions are possible from a sociological perspective. Turkle (1995) distinguishes between cultures of calculation and cultures of simulation and relates these cultures to the distinction between modernity and postmodernity, respectively. What can we understand about contemporary simulation practices in science by looking at them from the point of view of these two computer cultures? What new questions does such an analysis raise for further studies? On the basis of two case studies, the present paper compares and discusses simulation activities in astrophysics and meteorology. It argues that simulation practices manifest aspects of both of these cultures simultaneously, but in different situations. By employing the dichotomies surface/depth, play/seriousness, and extreme/reasonable to characterize and operationalize cultures of calculation and cultures of simulation as sensitizing concepts, the analysis shows how simulation code work shifts from development to use, the importance of but also resistance towards too much visualizations, and how simulation modelers play with extreme values, yet also try to achieve reasonable results compared to observations.

Full Text Available In recent years nuclear magnetic resonance (NMR sensors have been increasingly applied to investigate, characterize and monitor objects of cultural heritage interest. NMR is not confined to a few specific applications, but rather its use can be successfully extended to a wide number of different cultural heritage issues. A breakthrough has surely been the recent development of portable NMR sensors which can be applied in situ for non-destructive and non-invasive investigations. In this paper three studies illustrating the potential of NMR sensors in this field of research are reported.

Application of Stochastic Sensitivity Analysis to Integrated Force Method

2012-01-01

Full Text Available As a new formulation in structural analysis, Integrated Force Method has been successfully applied to many structures for civil, mechanical, and aerospace engineering due to the accurate estimate of forces in computation. Right now, it is being further extended to the probabilistic domain. For the assessment of uncertainty effect in system optimization and identification, the probabilistic sensitivity analysis of IFM was further investigated in this study. A set of stochastic sensitivity analysis formulation of Integrated Force Method was developed using the perturbation method. Numerical examples are presented to illustrate its application. Its efficiency and accuracy were also substantiated with direct Monte Carlo simulations and the reliability-based sensitivity method. The numerical algorithm was shown to be readily adaptable to the existing program since the models of stochastic finite element and stochastic design sensitivity are almost identical.

Type 2 diabetes affects Chinese Americans at an alarming rate. To address this health disparity, research in the area of cultural sensitivity and health literacy provides useful guidelines for creating culturally appropriate health education. In this article, we use discourse analysis to examine a group of locally available, Chinese- and English-language diabetes print documents from a surface level and deep structure level of culture. First, we compared these documents to research findings about printed health information to determine whether and how these documents apply current best practices for health literacy and culturally appropriate health communication. Second, we examined how diabetes as a disease and diabetes management is being constructed. The printed materials addressed surface level culture through the use of Chinese language, pictures, foods, and exercises. From a deeper cultural level, the materials constructed diabetes management as a matter of measurement and control that contrasted with previous research suggesting an alternative construction of balance. A nuanced assessment of both surface and deeper levels of culture is essential for creating health education materials that are more culturally appropriate and can lead to increased health literacy and improved health outcomes.

It has been shown that exposure to radiation of LED sources of light with an emission band maximum at about 465 and 520 nm having substantially identical damaging effects on animal cells in culture, that are in a logarithmic growth phase and preincubated with pigment. Photobiological effect is caused by photodynamic processes involving singlet oxygen generated by triplet excited sensitizer. Mono-exponential type dependence of cell survival on the energy dose indicates that it is bilirubin that acts as a sensitizer but not its photoproducts. The inclusion of bilirubin in the cells, where it is primarily localized in the mitochondria cells, it is accompanied by multiple amplification photochemical stability compared to pigment molecules bound with albumin

Cultural pathways through universal development.

Greenfield, Patricia M; Keller, Heidi; Fuligni, Andrew; Maynard, Ashley

2003-01-01

We focus our review on three universal tasks of human development: relationship formation, knowledge acquisition, and the balance between autonomy and relatedness at adolescence. We present evidence that each task can be addressed through two deeply different cultural pathways through development: the pathways of independence and interdependence. Whereas core theories in developmental psychology are universalistic in their intentions, they in fact presuppose the independent pathway of development. Because the independent pathway is therefore well-known in psychology, we focus a large part of our review on empirically documenting the alternative, interdependent pathway for each developmental task. We also present three theoretical approaches to culture and development: the ecocultural, the sociohistorical, and the cultural values approach. We argue that an understanding of cultural pathways through human development requires all three approaches. We review evidence linking values (cultural values approach), ecological conditions (ecocultural approach), and socialization practices (sociohistorical approach) to cultural pathways through universal developmental tasks.

Experience of using an interdisciplinary task force to develop a culturally sensitive multipronged tool to improve stroke outcomes in Nigeria

2016-09-01

Full Text Available The burden of stroke is on the rise in Nigeria. A multi-faceted strategy is essential for reducing this growing burden and includes promoting medication adherence, optimizing traditional biomarker risk targets (blood pressure, cholesterol and encouraging beneficial lifestyle practices. Successful implementation of this strategy is challenged by inadequate patient health literacy, limited patient/medical system resources, and lack of a coordinated interdisciplinary treatment approach. Moreover, the few interventions developed to improve medical care in Nigeria have generally been aimed at physicians (primarily and nurses (secondarily with minimal input from other key health care providers, and limited contributions from patients, caregivers, and the community itself. The Tailored Hospital-based Risk Reduction to Impede Vascular Events after Stroke (THRIVES study is assessing the efficacy of a culturally sensitive multidimensional intervention for controlling blood pressure in recent stroke survivors. A key component of the intervention development process was the constitution of a project task force comprising various healthcare providers and administrators. This paper describes the unique experience in Sub-Saharan Africa of utilizing of an interdisciplinary Task force to facilitate the development of the multipronged behavioral intervention aimed at enhancing stroke outcomes in a low-middle income country.

2016-11-01

Full Text Available Background: Orphans and other vulnerable children (OVC who grow up in institutional care often show communication and language problems. The caregivers lack training, and there are few language didactics programmes aimed at supporting communication and language development in OVC in institutional care in Tanzania. Objectives: The purpose of the study was to adapt the German concept of relational communication therapy (RCT as a support to language development in a Tanzanian early childhood education context in a culturally sensitive way. Following the adaptation of the concept, a training programme for Tanzanian caregiver students was developed to compare their competencies in language didactics before and after training. Methods: A convergent mixed methods design was used to examine changes following training in 12 participating caregiver students in a Tanzanian orphanage. The competencies in relational language didactics were assessed by a self-developed test and video recordings before and after intervention. Based on the results, we drew conclusions regarding necessary modifications to the training modules and to the concept of RCT. Results: The relational didactics competencies of the caregiver students improved significantly following their training. A detailed analysis of the four training modules showed that the improvement in relational didactics competencies varied depending on the topic and the teacher. Conclusion: The results provide essential hints for the professionalisation of caregivers and for using the concept of RCT for OVC in institutional care in Tanzania. Training programmes and concepts should not just be transferred across different cultures, disciplines and settings; they must be adapted to the specific cultural setting.

2016-04-01

Contemporary emphasis on creating culturally relevant and context specific knowledge increasingly drives researchers to conduct their work in settings outside their home country. This often requires researchers to build relationships with various stakeholders who may have a vested interest in the research. This case study examines the tension between relationship development with stakeholders and maintaining study integrity, in the context of potential harms, data credibility and cultural sensitivity. We describe an ethical breach in the conduct of global health research by a arising from the ad-hoc participation of a community stakeholder external to the visiting research group. A framework for reflection is developed from a careful examination of underlying factors and presented with a discussion of consequences and mitigation measures. This framework aims to present lessons learned for researchers working abroad who might face similar situations in their work. © 2015 John Wiley & Sons Ltd.

Culturally responsible curriculum development in hospitality, tourism and events management

Directory of Open Access Journals (Sweden)

Erwin Losekoot

2014-06-01

Full Text Available This paper considers the importance of the Treaty of Waitangi (1840 to Higher Education in New Zealand and how this influences the educational experience of hospitality, tourism and event management students. The paper reviews the literature on cultural diversity, internationalization and curriculum development, the role of culture in educating domestic and international students, and how the acculturation Higher Education students experience as part of their studies might lead to a deeper understanding of culture and identity in the hospitality workplace. The gap in the literature concerns how a higher education curriculum can assist in the development of cultural awareness and an understanding of historical commitments. The paper therefore identifies a number of key principles which are regarded as essential to the identity of those living in New Zealand/Aotearoa. The paper then goes on to illustrate how these principles could be applied to Higher Education. It suggests that these principles enshrined in the Treaty of Waitangi are also worth considering when creating an inclusive curriculum which supports all hospitality, tourism and events management students, irrespective of ethnic background, culture or upbringing. Finally, this paper proposes a matrix of ‘hooks’ - tools which academics can use to ensure their lectures address the needs of all learners. This matrix is developed from a study of the educational goals of the Principles of the Treaty of Waitangi (ToW, the founding document of this country. This research adds value by creating an awareness of the diverse environment in which academics and students operate, thereby enabling students to develop a cultural sensitivity to the international hospitality industry they will be employed in on graduation.

Sensitivity analysis technique for application to deterministic models

The characterization of sever accident source terms for light water reactors should include consideration of uncertainties. An important element of any uncertainty analysis is an evaluation of the sensitivity of the output probability distributions reflecting source term uncertainties to assumptions regarding the input probability distributions. Historically, response surface methods (RSMs) were developed to replace physical models using, for example, regression techniques, with simplified models for example, regression techniques, with simplified models for extensive calculations. The purpose of this paper is to present a new method for sensitivity analysis that does not utilize RSM, but instead relies directly on the results obtained from the original computer code calculations. The merits of this approach are demonstrated by application of the proposed method to the suppression pool aerosol removal code (SPARC), and the results are compared with those obtained by sensitivity analysis with (a) the code itself, (b) a regression model, and (c) Iman's method

Broadhead, B.L.; Hopper, C.M.; Childs, R.L.; Parks, C.V.

1999-01-01

This report presents the application of sensitivity and uncertainty (S/U) analysis methodologies to the code/data validation tasks of a criticality safety computational study. Sensitivity and uncertainty analysis methods were first developed for application to fast reactor studies in the 1970s. This work has revitalized and updated the available S/U computational capabilities such that they can be used as prototypic modules of the SCALE code system, which contains criticality analysis tools currently used by criticality safety practitioners. After complete development, simplified tools are expected to be released for general use. The S/U methods that are presented in this volume are designed to provide a formal means of establishing the range (or area) of applicability for criticality safety data validation studies. The development of parameters that are analogous to the standard trending parameters forms the key to the technique. These parameters are the D parameters, which represent the differences by group of sensitivity profiles, and the ck parameters, which are the correlation coefficients for the calculational uncertainties between systems; each set of parameters gives information relative to the similarity between pairs of selected systems, e.g., a critical experiment and a specific real-world system (the application)

Full Text Available A rapid and sensitive method to quantitatively assess N-acetylglucosaminidase (NAG activity in cultured cells is highly desirable for both basic research and clinical studies. NAG activity is deficient in cells from patients with Mucopolysaccharidosis type IIIB (MPS IIIB due to mutations in NAGLU, the gene that encodes NAG. Currently available techniques for measuring NAG activity in patient-derived cell lines include chromogenic and fluorogenic assays and provide a biochemical method for the diagnosis of MPS IIIB. However, standard protocols require large amounts of cells, cell disruption by sonication or freeze-thawing, and normalization to the cellular protein content, resulting in an error-prone procedure that is material- and time-consuming and that produces highly variable results. Here we report a new procedure for measuring NAG activity in cultured cells. This procedure is based on the use of the fluorogenic NAG substrate, 4-Methylumbelliferyl-2-acetamido-2-deoxy-alpha-D-glucopyranoside (MUG, in a one-step cell assay that does not require cell disruption or post-assay normalization and that employs a low number of cells in 96-well plate format. We show that the NAG one-step cell assay greatly discriminates between wild-type and MPS IIIB patient-derived fibroblasts, thus providing a rapid method for the detection of deficiencies in NAG activity. We also show that the assay is sensitive to changes in NAG activity due to increases in NAGLU expression achieved by either overexpressing the transcription factor EB (TFEB, a master regulator of lysosomal function, or by inducing TFEB activation chemically. Because of its small format, rapidity, sensitivity and reproducibility, the NAG one-step cell assay is suitable for multiple procedures, including the high-throughput screening of chemical libraries to identify modulators of NAG expression, folding and activity, and the investigation of candidate molecules and constructs for applications in

Relationship education, effective in improving relationship quality among different-sex couples, represents a promising and nonstigmatizing approach to promoting the health and stability of same-sex couples. A new culturally sensitive relationship education program was developed specifically for male same-sex couples, which includes adaptations of evidence-based strategies to build core relationship skills (e.g., communication skills training) and newly developed content to address unique challenges faced by this group (e.g., discrimination; low social support). A small randomized waitlist-control trial (N = 20 couples) was conducted to evaluate the program. To assess program efficacy, dyadic longitudinal data (collected at pre- and postprogram and 3-month follow-up) were analyzed using multilevel models that accounted for nonindependence in data from indistinguishable dyads. Results indicated significant program effects in comparison to waitlist controls on couple constructive and destructive communication, perceived stress, and relationship satisfaction. Gains in each of these areas were maintained at 3-month follow-up. Although there was no evidence of within-person program effects on social support, satisfaction, or relationship instability immediately postprogram, all 3 showed within-person improvements by follow-up. Ratings of program satisfaction were high. In summary, study findings support the feasibility, acceptability, and initial efficacy of the program and highlight the potential value of culturally sensitive adaptations of relationship education for same-sex couples.

Full Text Available This paper discusses the perceptions of Egyptian minority groups in relation to internet information technology with which they feel empowered to protect, affirm and communicate their oppressed existence, on local and global dimensions. The research employs qualitative methods and interpretive analysis, to focus on the use of Internet information technology tools by Egyptian minority groups, in particular, their online platforms and chat rooms, and the related issues associated with these practices and usages. The paper argues that cyberspace is used by specific minority groups in Egypt as a "gateway to freedom" in which it constitutes an ally to establish newly founded cyber identities that aide them to exercise their basic human rights of freedom of thought, speech and expression. The paper thus examines cyberspace a medium or tool for the carrying out of information exchange without the traditional fear of politics and power that is deeply engraved in the roots of the Egyptian culture. In this way, these minority groups are analysed as the newly conceived human information systems (HIS residing on Internet information technology and infrastructure. The paper proposes an adaptive and culturally sensitive model of human information systems as well as human information systems development life cycle (HISDLC to aid in establishing effective processes of information exchange and creation, hence assisting in the emancipation of conflicting parties residing in Egypt, elsewhere in the Middle East and globally.

Full Text Available Abstract Background This paper describes the process used to develop an integrated set of culturally sensitive, evidence-based counselling tools (job aids by using qualitative participatory research. The aim of the intervention was to contribute to improving infant feeding counselling services for HIV positive women in the Kilimanjaro Region of Tanzania. Methods Formative research using a combination of qualitative methods preceded the development of the intervention and mapped existing practices, perceptions and attitudes towards HIV and infant feeding (HIV/IF among mothers, counsellors and community members. Intervention Mapping (IM protocol guided the development of the overall intervention strategy. Theories of behaviour change, a review of the international HIV/IF guidelines and formative research findings contributed to the definition of performance and learning objectives. Key communication messages and colourful graphic illustrations related to infant feeding in the context of HIV were then developed and/or adapted from existing generic materials. Draft materials were field tested with intended audiences and subjected to stakeholder technical review. Results An integrated set of infant feeding counselling tools, referred to as 'job aids', was developed and included brochures on feeding methods that were found to be socially and culturally acceptable, a Question and Answer Guide for counsellors, a counselling card on the risk of transmission of HIV, and an infant feeding toolbox for demonstration. Each brochure describes the steps to ensure safer infant feeding using simple language and images based on local ideas and resources. The brochures are meant to serve as both a reference material during infant feeding counselling in the ongoing prevention of mother to child transmission (pMTCT of HIV programme and as take home material for the mother. Conclusion The study underscores the importance of formative research and a systematic theory

Full Text Available We created an automated bioassay system based on inkjet printing. Compared to conventional manual bacterial culture systems our printing approach improves the quality as well as the processing speed. A hydrophobic/hydrophilic pattern as a container supporting a culture medium was built on filter paper using a toluene solution of polystyrene for hydrophobization, followed by toluene printing to create several hydrophilic areas. As culture media we used a novel poly(vinyl alcohol based hydrogel and a standard calcium alginate hydrogel. The poly(vinyl alcohol hydrogel was formed by physical crosslinking poly(vinyl alcohol with adipic acid dihydrazide solutions. The conditions of poly(vinyl alcohol gelation were optimized for inkjet printability and the optimum mixture ratio was determined. The calcium alginate hydrogel was formed by chemical reaction between sodium alginate and CaCl2 solutions. Together with nutrients both hydrogel solutions were successfully printed on paper by means of the modified inkjet printer. The amount of each solution was demanded simply by outputting CMYK values. In the last step bacterial cells were printed on both hydrogel media. For both media we achieved a stable bacteria growth which was confirmed by microscopical imaging of the developed bacterial colonies.

2013-01-01

There are inequalities in health among migrants and local populations in Europe. Due to migration, Germany, Norway and Sweden have become ethnic culturally diverse nations. There are barriers to mental health care access for refugees, migrants and minorities, and problems with quality of culturally sensitive care in the three countries. This is despite tax-funded health care systems based on equity in service provision. There is a need to develop culturally sensitive mental health services that respond to the increasing diversity of the populations. In this chapter, we will take a closer look at cultural diversity in the countries in question, discuss challenges and give examples of current work to open up mental health services to cultural diversity. The German example will focus on the movement of Interkulturelle Öffnung (cross-cultural opening of the health care system) and work on creating national guidelines and quality standards. From Norway, the work of the National Centre for Mental Health for the indigenous Sámi population will be presented. The Swedish example will focus on the work carried out by the Transcultural Centre. The latter is a competence centre supporting development of culturally sensitive care as an integrated part of the regional health and mental health care system in Stockholm. Finally, the relevance of mental health care for a culturally diverse population, as a part of the larger social project of building tolerant multicultural societies, will be discussed.

Hong, Sungchul; Vonderohe, Alan P

2014-02-10

Uncertainty and sensitivity analysis methods are introduced, concerning the quality of spatial data as well as that of output information from Global Positioning System (GPS) and Geographic Information System (GIS) integrated applications for transportation. In the methods, an error model and an error propagation method form a basis for formulating characterization and propagation of uncertainties. They are developed in two distinct approaches: analytical and simulation. Thus, an initial evaluation is performed to compare and examine uncertainty estimations from the analytical and simulation approaches. The evaluation results show that estimated ranges of output information from the analytical and simulation approaches are compatible, but the simulation approach rather than the analytical approach is preferred for uncertainty and sensitivity analyses, due to its flexibility and capability to realize positional errors in both input data. Therefore, in a case study, uncertainty and sensitivity analyses based upon the simulation approach is conducted on a winter maintenance application. The sensitivity analysis is used to determine optimum input data qualities, and the uncertainty analysis is then applied to estimate overall qualities of output information from the application. The analysis results show that output information from the non-distance-based computation model is not sensitive to positional uncertainties in input data. However, for the distance-based computational model, output information has a different magnitude of uncertainties, depending on position uncertainties in input data.

Objective To assess whether the National Tuberculosis Program (NTP) guidelines for culture and drug sensitivity testing (DST) in Guatemala were successfully implemented, particularly in cases of smear-negative pulmonary tuberculosis (TB) or previously treated TB, by documenting notification rates by department (geographic area), disease type and category, and culture and DST results. Methods This was a cross-sectional, operational research study that merged and linked all patients registered by the NTP and the National Reference Laboratory in 2013, eliminating duplicates. The proportions with culture (for new smear negative pulmonary cases) and culture combined with DST (for previously treated patients) were estimated and analyzed by department. Data were analyzed using EpiData Analysis version 2.2. Results There were 3 074 patients registered with TB (all forms), for a case notification rate of 20/100 000 population. Of these, 2 842 had new TB, of which 2 167 (76%) were smear-positive pulmonary TB (PTB), 385 (14%) were smear-negative PTB, and 290 (10%) were extrapulmonary TB. There were 232 (8%) previously treated cases. Case notification rates (all forms) varied by department from 2-68 per 100 000 population, with the highest rates seen in the southwest and northeast part of Guatemala. Of new TB patients, 136 had a culture performed and 55 had DST of which the results were 33 fully sensitive, 9 monoresistant, 3 polyresistant, and 10 multidrug resistant TB (MDR-TB). Only 21 (5%) of new smear-negative PTB patients had cultures. Of 232 previously treated patients, 54 (23%) had a culture and 47 (20%) had DST, of which 29 were fully sensitive, 7 monoresistant, 2 polyresistant, and 9 MDR-TB. Of 22 departments (including the capital), culture and DST was performed in new smear-negative PTB in 7 departments (32%) and in previously treated TB in 13 departments (59%). Conclusions Despite national guidelines, only 5% of smear-negative PTB cases had a culture and only 20% of

Living in a social community, the culture of an enterprise is certainly under the influence of that society. Safety culture of nuclear utilities is the core of the enterprise culture. As a formal expression as defined in INSAG 3 and 4 by IAEA, it as a matter of fact originated from the summing up of the experiences of western nuclear industry, particularly after such epoch-making accidents of Three Miles Island and Chernobyl. In view of the geographical culture theory, whether or not this conception of western industrial culture will be absorbed and assimilated by Chinese Nuclear Industry is a challenging issue. This is because, on the one hand, Nuclear Power is comparatively speaking a newly developing industry in China and, on the other hand, China has enjoyed an uninterrupted history of traditional culture over five thousand years. In other words, whether the new and alien values will conflict with or be constructively assimilated by our traditional mindset is a critical question to be answered in any development program of safety culture.

Patients suffering from advanced stage hepatocellular carcinoma (HCC) often exhibit a poor prognosis or dismal clinical outcomes due to ineffective chemotherapy or a multi-drug resistance (MDR) process. Thus, it is urgent to develop a new chemotherapeutic sensitivity testing system for HCC treatment. The presence study investigated the potential application of a novel chemotherapeutic sensitivity-testing system based on a collagen gel droplet embedded 3D-culture system (CD-DST). Primary cells were separating from surgical resection specimens and then tested by CD-DST. To identify whether HCC cell lines or cells separating from clinical specimens contain MDR features, the cells were treated with an IC 50 (half maximal inhibitory concentration) or IC max (maximal inhibitory concentration) concentration of antitumor agents, e.g., 5-furuolouracil (5-FU), paclitaxel (PAC), cisplatin (CDDP), epirubicin (EPI), or oxaliplatin (L-OHP), and the inhibitory rates (IRs) were calculated. HepG2 cells were sensitive to 5-FU, PAC, CDDP, EPI, or L-OHP; the IC 50 value is 0.83 ± 0.45 μg/ml, 0.03 ± 0.02 μg/ml, 1.15 ± 0.75 μg/ml, 0.09 ± 0.03 μg/ml, or 1.76 ± 0.44 μg/ml, respectively. Only eight (8/26), nine (9/26), or five (5/26) patients were sensitive to the IC max concentration of CDDP, EPI, or L-OHP; whereas only three (3/26), four (4/26), or two (2/26) patients were sensitive to the IC 50 concentration of CDDP, EPI, or L-OHP. No patients were sensitive to 5-FU or PAC. The in vitro drug sensitivity exanimation revealed the MDR features of HCC and examined the sensitivity of HCC cells from clinical specimens to anti-tumor agents. CD-DST may be a useful method to predict the potential clinical benefits of anticancer agents for HCC patients.

A call to improve practice concerning cultural sensitivity in advance directives: a review of the literature.

Science.gov (United States)

Zager, B Sue; Yancy, Margaret

2011-12-01

The Patient Self Determination Act of 1990 mandates healthcare providers (HCP) to speak with patients about end-of-life preferences and advance directives (AD). HCP work with patients of varying cultures, and standard ADs do not address cultural differences. In order to understand various cultural beliefs, cultural sensitivity is important especially when discussing advance care planning (ACP). Individuals from differing ethnic backgrounds are likely to turn to their traditional norms of practice when ill or treatment choices must be made. An AD that addresses varying cultural values and beliefs was sought. A comprehensive review of the literature was conducted. Articles selected for review included qualitative and quantitative studies. The evidence was evaluated and synthesized for information related to cultural sensitivity and ADs. Three common themes emerged related to ACP discussions and culture. Healthcare provider awareness, communication, and education concerning cultural differences and ACP assisted in meeting the needs for end-of-life planning in the current era of increased globalization. Education for HCP on cultural differences and how to lead discussions promoted ACP. ADs are an essential part of health care and promote patient-centered care. (HCP) should be able to recognize differing cultural values and beliefs in order to initiate conversations about end of life. Initiating conversations about ACP can be facilitated by using open-ended questions that respect the values and beliefs of various cultures. Copyright ©2011 Sigma Theta Tau International.

Cultural influences on the physician-patient encounter: The case of shared treatment decision-making.

In this paper we discuss the influence of culture on the process of treatment decision-making, and in particular, shared treatment decision-making in the physician-patient encounter. We explore two key issues: (1) the meaning of culture and the ways that it can affect treatment decision-making; (2) cultural issues and assumptions underlying the development and use of treatment decision aids. This is a conceptual paper. Based on our knowledge and reading of the key literature in the treatment decision-making field, we looked for written examples where cultural influences were taken into account when discussing the physician-patient encounter and when designing instruments (decision aids) to help patients participate in making decisions. Our assessment of the situation is that to date, and with some recent exceptions, research in the above areas has not been culturally sensitive. We suggest that more research attention should be focused on exploring potential cultural variations in the meaning of and preferences for shared decision-making as well as on the applicability across cultural groups of decision aids developed to facilitate patient participation in treatment decision-making with physicians. Both patients and physicians need to be aware of the cultural assumptions underlying the development and use of decision aids and assess their cultural sensitivity to the needs and preferences of patients in diverse cultural groups.

Chemically induced skin sensitization is a complex immunological disease with a profound impact on quality of life and working ability. Despite some progress in developing alternative methods for assessing the skin sensitization potential of chemical substances, there is no in vitro test that correlates well with human data. Computational QSAR models provide a rapid screening approach and contribute valuable information for the assessment of chemical toxicity. We describe the development of a freely accessible web-based and mobile application for the identification of potential skin sensitizers. The application is based on previously developed binary QSAR models of skin sensitization potential from human (109 compounds) and murine local lymph node assay (LLNA, 515 compounds) data with good external correct classification rate (0.70-0.81 and 0.72-0.84, respectively). We also included a multiclass skin sensitization potency model based on LLNA data (accuracy ranging between 0.73 and 0.76). When a user evaluates a compound in the web app, the outputs are (i) binary predictions of human and murine skin sensitization potential; (ii) multiclass prediction of murine skin sensitization; and (iii) probability maps illustrating the predicted contribution of chemical fragments. The app is the first tool available that incorporates quantitative structure-activity relationship (QSAR) models based on human data as well as multiclass models for LLNA. The Pred-Skin web app version 1.0 is freely available for the web, iOS, and Android (in development) at the LabMol web portal ( http://labmol.com.br/predskin/ ), in the Apple Store, and on Google Play, respectively. We will continuously update the app as new skin sensitization data and respective models become available.

1984-01-01

A method that permits high-energy β-irradiation to be applied to individual lymphocyte microplate cultures is described. The principle involves the introduction of single energy sources (in this case 32 P) contained within tubes which rest inside wells containing the lymphocyte cultures. Cell viability and mitogen-induced transformation were studied under these conditions. Dose-response effects were clearly demonstrated. The method is simple and, provided the precautions described are adhered to, safe. It should be applicable to studies of radiation sensitivity of putative target cells in various clinical situations.

Hallucinogenic drugs were used to treat alcoholic patients in the past, and recent developments in the study of hallucinogens led to a renewal of interest regarding the application of these drugs in the treatment of addiction. In this scenario, accumulating evidence suggests that the hallucinogenic brew ayahuasca (Aya) may have therapeutic effects on substance abuse problems. We investigated the effects of Aya on spontaneous locomotor activity and ethanol(Eth)-induced hyperlocomotion and subsequent locomotor sensitization by a two-injection protocol. Additionally, we tested the effect of Aya on an 8-day counter-sensitization protocol to modify sensitized responses induced by a repeated treatment with Eth (1.8g/kg) for 8 alternate days. Aya showed high sensitivity in preventing the development of Eth-induced behavioral sensitization, attenuating it at all doses (30, 100, 200, 300 or 500 mg/kg) without modifying spontaneous locomotor activity. At the highest doses (300 and 500 mg/kg), Aya also showed selectivity to both acute and sensitized Eth responses. Finally, a counter-sensitization strategy with 100 or 300 mg/kg of Aya for 8 consecutive days after the establishment of Eth-induced behavioral sensitization was effective in blocking its subsequent expression on an Eth challenge. We demonstrated that Aya not only inhibits early behaviors associated with the initiation and development of Eth addiction, but also showed effectiveness in reversing long-term drug effects expression, inhibiting the reinstatement of Eth-induced behavioral sensitization when administered in the Eth-associated environment.

As a prerequisite for active involvement, patients need to be informed in an adequate and preference-sensitive way. Interactive Health Communication Applications (IHCAs that combine web-based health information for patients with additional support offer the opportunity to reach great numbers of patients at low cost and provide them with high-quality information and support at the time, place, and learning speed they prefer. Still, web-based interventions often suffer from high attrition. Tailoring the intervention to patients’ needs and preferences might reduce attrition and should thereby increase effectiveness. The purpose of this study was to develop a tailored IHCA offering evidence-based, preference-sensitive content and treatment decision support to patients with type 2 diabetes. The content was developed based on a needs assessment and two evidence-based treatment guidelines. The delivery format is a dialogue-based, tunneled design tailoring the content and tone of the dialogue to relevant patient characteristics (health literacy, attitudes toward self-care, and psychological barriers to insulin treatment. Both content and tailoring were revised by an interdisciplinary advisory committee.Conclusion: The World Wide Web holds great potential for patient information and self-management interventions. With the development and evaluation of a tailored IHCA, we complement face-to-face consultations of patients with their health care practitioners and make them more efficient and satisfying for both sides.

Perspectives of weather and sensitivities to heat: Social media applications for cultural climatology

Science.gov (United States)

Austin, Bradley J.

This dissertation explores the cultural significance and physical perception of heat evident in a corpus of Twitter messages collected for six cities across the US over a seven-week period following historic heat events in the summer of 2012. Through a mixed-methods analysis of what weather means and how it feels, emergent conceptual tools are put forth that seek to envisage weather and society as co-productive, and sometimes indistinguishable, elements in a broader ecological process of world formation. Following a review of concepts from literature on everyday interactions with weather, the dissertation proceeds with two analytical chapters. The first analysis is textual and focuses on 'weather typing' as a discursive practice that works to produce abstract spaces with, of, and for weather through the conceptual distancing of the environment from the body. These practices are considered constitutive of situated perspectives of weather, many of which show a latent influence of heat, be it in the form of shared bodily energy or as an ambient environmental factor. The second analysis quantitatively explores emotional and physiological sensitivities to heat through transforming textual indicators into metrics that can be meaningfully tracked over time alongside biometeorological constructs, particularly with apparent temperature. Each analysis is intended to open the study of weather to multiple lines of inquiry across different scales while remaining rooted in empirical observation. The conclusion of the dissertation is left open as a discussion on further uses of these concepts and analytical strategies in hopes that they may find uses in different contexts, with different data sources, and through a variety of theoretical lenses.

Full Text Available Tourism is a complex activity whose development is manifested in a fast pace, which in the last period determined it to become one of the most spectacular phenomena of recent decades, with important economic effects and particularly, social and human effects. This form of cultural tourism is identified as an engine for development and promotion of local cultural identities, offering neighboring communities an opportunity to preservation of cultural heritage as a resource for socio-economic local development. Thus, cultural tourism is the boundary between culture and tourism industry, its development influencing each other. Cultural tourism is a form of economic development based on cultural resources, contributing to national economic development.

Napier grass Stunt Disease (NSD) is a severe disease of Napier grass (Pennisetum purpureum) in Eastern Africa, caused by the leafhopper-transmitted bacterium Candidatus Phytoplasma oryzae. The pathogen severely impairs the growth of Napier grass, the major fodder for dairy cattle in Eastern Africa. NSD is associated with biomass losses of up to 70% of infected plants. Diagnosis of NSD is done by nested PCR targeting the phytoplasma DNA, which is difficult to perform in developing countries with little infrastructure. We report the development of an easy to use, rapid, sensitive and specific molecular assay for field diagnosis of NSD. The procedure is based on recombinase polymerase amplification and targets the imp gene encoding a pathogen-specific immunodominant membrane protein. Therefore we followed a two-step process. First we developed an isothermal DNA amplification method for real time fluorescence application and then transferred this assay to a lateral flow format. The limit of detection for both procedures was estimated to be 10 organisms. We simplified the template preparation procedure by using freshly squeezed phloem sap from Napier grass. Additionally, we developed a laboratory serological assay with the potential to be converted to a lateral flow assay. Two murine monoclonal antibodies with high affinity and specificity to the immunodominant membrane protein IMP of Candidatus Phytoplasma oryzae were generated. Both antibodies specifically reacted with the denatured or native 17 kDa IMP protein. In dot blot experiments of extracts from infected plant, phytoplasmas were detected in as little as 12,5 μg of fresh plant material. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Families of patients with dementia may need support in difficult end-of-life decision making. Such guidance may be culturally sensitive. To support families in Canada, a booklet was developed to aid decision making on palliative care issues. For reasons of cost effectiveness and promising effects, we prepared for its implementation in Italy, the Netherlands and Japan. Local teams translated and adapted the booklet to local ethical, legal and medical standards where needed, retaining guidance on palliative care. Using qualitative content analyses, we grouped and compared adaptations to understand culturally sensitive aspects. Three themes emerged: (1) relationships among patient, physician and other professionals-the authority of the physician was more explicit in adapted versions; (2) patient rights and family position-adding detail about local regulations; and (3) typology of treatments and decisions. Considerations underlying palliative care decisions were detailed (Dutch and Italian versions), and the Japanese version frequently referred to professional and legal standards, and life-prolongation was a competing goal. Text on artificial feeding or fluids and euthanasia was revised extensively. Providing artificial feeding and fluids and discussing euthanasia may be particularly sensitive topics, and guidance on these subjects needs careful consideration of ethical aspects and possible adaptations to local standards and practice. The findings may promote cross-national debate on sensitive, core issues regarding end-of-life care in dementia.

Public demand for safer care has catapulted the healthcare industry's efforts to understand relationships between patient safety and hospital performance. This study explored linkages between staff perceptions of safety culture (SC) and ongoing measures of hospital nursing unit-based structures, care processes, and adverse patient outcomes. Relationships between nursing-sensitive measures of hospital performance and SC were explored at the unit-level from 9 California hospitals and 37 nursing units. SC perceptions were measured 6 months prior to collection of nursing metrics and relationships between the two sets of data were explored using correlational and regression analyses. Significant relationships were found with reported falls and process measures for fall prevention. Multiple associations were identified with SC and the structure of care delivery: skill mix, staff turnover, and workload intensity demonstrated significant relationships with SC, explaining 22-45% of the variance. SC was an important factor to understand in the quest to advance safe patient care. These findings have affordability and care quality implications for hospital leadership. When senior leaders prioritized a safety culture, patient outcomes may have improved with less staff turnover and more productivity. A business case could be made for investing in patient safety systems to provide reliably safe care. © 2013 National Association for Healthcare Quality.

Delivering pediatric rehabilitation services to immigrant parents of children with disabilities requires the practice of culturally sensitive care. Few studies have examined the specific nature of culturally sensitive care in pediatric rehabilitation, especially the notions of effective communication and client engagement. Interviews were held with 42 therapists (10 social workers, 16 occupational therapists and 16 speech language pathologists) from two locations in Canada (Toronto and Quebec City). Data were analyzed using an inductive content analysis approach. Study themes included the importance and nature of effective communication and client engagement in service delivery involving immigrant parents. Participants discussed using four main types of strategies to engage immigrant parents, including understanding the family situation, building a collaborative relationship, tailoring practice to the client's situation and ensuring parents' understanding of therapy procedures. The findings illuminate the importance of effective, two-way communication in providing the mutual understanding needed by therapists to engage parents in the intervention process. The findings also richly describe the engagement strategies used by therapists. Clinical implications include recommendations for strategies for therapists to employ to engage this group of parents. Furthermore, the findings are applicable to service provision in general, as engaging families in a collaborative relationship through attention to their specific situation is a general principle of good quality, family-centered care. Implications for Rehabilitation Effective communication permeates the delivery of culturally sensitive care and provides mutual understanding, which is fundamental to client engagement. The findings illuminate the nature of "partnership" by indicating the role of collaborative therapist strategies in facilitating engagement. Four main strategies facilitate effective communication and

Organizational Culture and Scale Development: Methodological Challenges and Future Directions

Full Text Available Defining and measuring organizational culture (OC is of paramount importance to organizations because a strong culture could potentially increase service quality and yield sustainable competitive advantages. However, such process could be challenging to managers because the scope of OC has been defined differently across disciplines and industries, which has led to the development of various scales for measuring OC. In addition, previously developed OC scales may also not be fully applicable in the hospitality and tourism context. Therefore, by highlighting the key factors affecting the business environment and the unique characteristics of hospitality industry, this paper aims to align the scope of OC closely with the industry and to put forth the need for a new OC scale that accurately responds to the context of the hospitality industry.

Full Text Available A major challenge for tourism in the modern world is an increasing need for new tourist attractions and products in destinations. The tourism industry adapts to the demands of modern tourism market, introducing innovations to existing destinations and activities. In order to improve the presentation of tourism and cultural heritage of consumption goods, it is necessary to encourage the development of cultural tourist routes that would be applicable in tourism practices. In this case, it refers to the ability to create thematic cultural routes that would have a focus on specific historical and cultural values in the Petrovaradin fortress. The aim of this study, based on the opinions of experts and local people - visitors about the values and potential of the Fortress, was to identify key values, and the possibility that the cultural and historical values are the basis for the creation of thematic cultural routes. The result is obtained via method of interviewing people - visitors, as well as through interviews with three different groups of respondents. This paper presents the views of respondents about the potential of the Fortress and its core values, based on which potential cultural thematic routes are suggested, as well as the results of direct study of the possibilities of creating them. In addition to the field and bibliographic research, the method of content analysis was also applied.

Novel Quantitative Real-Time LCR for the Sensitive Detection of SNP Frequencies in Pooled DNA: Method Development, Evaluation and Application

Science.gov (United States)

Psifidi, Androniki; Dovas, Chrysostomos; Banos, Georgios

2011-01-01

Background Single nucleotide polymorphisms (SNP) have proven to be powerful genetic markers for genetic applications in medicine, life science and agriculture. A variety of methods exist for SNP detection but few can quantify SNP frequencies when the mutated DNA molecules correspond to a small fraction of the wild-type DNA. Furthermore, there is no generally accepted gold standard for SNP quantification, and, in general, currently applied methods give inconsistent results in selected cohorts. In the present study we sought to develop a novel method for accurate detection and quantification of SNP in DNA pooled samples. Methods The development and evaluation of a novel Ligase Chain Reaction (LCR) protocol that uses a DNA-specific fluorescent dye to allow quantitative real-time analysis is described. Different reaction components and thermocycling parameters affecting the efficiency and specificity of LCR were examined. Several protocols, including gap-LCR modifications, were evaluated using plasmid standard and genomic DNA pools. A protocol of choice was identified and applied for the quantification of a polymorphism at codon 136 of the ovine PRNP gene that is associated with susceptibility to a transmissible spongiform encephalopathy in sheep. Conclusions The real-time LCR protocol developed in the present study showed high sensitivity, accuracy, reproducibility and a wide dynamic range of SNP quantification in different DNA pools. The limits of detection and quantification of SNP frequencies were 0.085% and 0.35%, respectively. Significance The proposed real-time LCR protocol is applicable when sensitive detection and accurate quantification of low copy number mutations in DNA pools is needed. Examples include oncogenes and tumour suppressor genes, infectious diseases, pathogenic bacteria, fungal species, viral mutants, drug resistance resulting from point mutations, and genetically modified organisms in food.

Neuroepithelial tumor cells were cultured in vitro. The biopsy material was taken from 93 children at removal of the brain tumors during neurosurgical operations. The individual features of the cells sensitivity of primary cultures in respect to protocol-approved chemotherapy drugs and changes in the Interleukin-6 (Il-6) level in the culture medium after the application of chemotherapy were established. The initial level of Il-6 exceeded 600.0 pg/ml in the cultural medium with histologically verified pilomyxoid astrocytoma cells, and ranged from 100.0 to 200.0 pg/ml in the medium at cultivation of ganglioneuroblastoma and pilocytic astrocytoma. A decrease in the Il-6 level in the medium culture of primary tumors cells was observed after the application of chemotherapeutic agents on the cells of pilomyxoid astrocytoma, astrocytomas, and pilocytic desmoplastic/nodular medulloblastoma. The production of Il-6 increased after application of cytostatic drugs on the cells of oligoastrocytomas. A decrease in Il-6 level after application of Cisplatin and Methotrexate and a 5-10 fold increase in the level of Il-6 after application of Etoposide, Carboplatin, Cytarabine, and Gemcitabine were registered in the medium with ganglioneuroblastoma. To improve the cytotoxic action of chemotherapeutic agents, the combined application of cytostatics with heterocyclic compounds was carried out. A computer modeling of ligand-protein complexes of carbamide using the Dock 6.4 and USF Chimera program packages was performed with molecular mechanics method. Special attention was drawn to the ability of several isoxazole heterocycles and isothiazolyl to inhibit the tyrosine kinase. It was proved in vitro that the joint application of chemotherapeutic agents and heterocyclic compounds could reduce the concentration of the cytostatic factor by 10 or more times, having maintained the maximum cytotoxic effect. It was assumed that the target amplification of cytotoxic action of chemotherapeutic

This study focused on a possible temperament-by-culture interaction. Specifically, it explored whether a basic temperament/personality trait (sensory processing sensitivity; SPS), perhaps having a genetic component, might moderate a previously established cultural difference in neural responses when making context-dependent vs context-independent judgments of simple visual stimuli. SPS has been hypothesized to underlie what has been called inhibitedness or reactivity in infants, introversion in adults, and reactivity or responsivness in diverse animal species. Some biologists view the trait as one of two innate strategies-observing carefully before acting vs being first to act. Thus the central characteristic of SPS is hypothesized to be a deep processing of information. Here, 10 European-Americans and 10 East Asians underwent functional magnetic resonance imaging while performing simple visuospatial tasks emphasizing judgments that were either context independent (typically easier for Americans) or context dependent (typically easier for Asians). As reported elsewhere, each group exhibited greater activation for the culturally non-preferred task in frontal and parietal regions associated with greater effort in attention and working memory. However, further analyses, reported here for the first time, provided preliminary support for moderation by SPS. Consistent with the careful-processing theory, high-SPS individuals showed little cultural difference; low-SPS, strong culture differences.

The purpose of this study was to ascertain if the simple practice of Gram stain, acridine orange stain and direct sensitivity determination of positive blood culture bottles could be used to guide early and appropriate treatment in trauma patients with clinical suspicion of sepsis. The study also aimed to evaluate the error in interpreting antimicrobial sensitivity by direct method when compared to standard method and find out if specific antibiotic-organism combination had more discrepancies. Findings from consecutive episodes of blood stream infection at an Apex Trauma centre over a 12-month period are summarized. A total of 509 consecutive positive blood cultures were subjected to Gram staining. AO staining was done in BacT/ALERT-positive Gram-stain negative blood cultures. Direct sensitivity was performed from 369 blood culture broths, showing single type of growth in Gram and acridine orange staining. Results of direct sensitivity were compared to conventional sensitivity for errors. No 'very major' discrepancy was found in this study. About 5.2 and 1.8% minor error rates were noted in gram-positive and gram-negative bacteria, respectively, while comparing the two methods. Most of the discrepancies in gram-negative bacteria were noted in beta lactam - beta lactamase inhibitor combinations. Direct sensitivity testing was not reliable for reporting of methicillin and vancomycin resistance in Staphylococci. Gram stain result together with direct sensitivity testing is required for optimizing initial antimicrobial therapy in trauma patients with clinical suspicion of sepsis. Gram staining and AO staining proved particularly helpful in the early detection of candidaemia.

The use of disposable bags for cell culture media storage has grown significantly in the past decade. Some of the key advantages of using disposable bags relative to non-disposable containers include increased product throughput, decreased cleaning validation costs, reduced risk of cross contamination and lower facility costs. As the scope of use of disposable bags for cell culture applications increases, problematic bags and scenarios should be identified and addressed to continue improving disposables technologies and meet the biotech industry's needs. In this article, we examine a cell culture application wherein media stored in disposable bags is warmed at 37°C before use for cell culture operations. A problematic bag film was identified through a prospective and retrospective cell culture investigation. The investigation provided information on the scope and variation of the issue with respect to different Chinese hamster ovary (CHO) cell lines, cell culture media, and application-specific parameters. It also led to the development of application-specific test methods and enabled a strategy for disposable bag film testing. The strategy was implemented for qualifying an alternative bag film for use in our processes. In this test strategy, multiple lots of 13 bag film types, encompassing eight vendors were evaluated using a three round, cell culture-based test strategy. The test strategy resulted in the determination of four viable bag film options based on the technical data. The results of this evaluation were used to conclude that a volatile or air-quenched compound, likely generated by gamma irradiation of the problematic bag film, negatively impacted cell culture performance. © 2013 American Institute of Chemical Engineers.

1989-01-01

The present work is an application of the perturbation theory (Matricial formalism) to a simplified two channels model, for sensitivity calculations in PWR cores. Expressions for some sensitivity coefficients of thermohydraulic interest were developed from the proposed model. The code CASNUR.FOR was written in FORTRAN to evaluate these sensitivity coefficients. The comparison between results obtained from the matrical formalism of pertubation theory with those obtained directly from the two channels model, makes evident the efficiency and potentiality of this perturbation method for nuclear reactor cores sensitivity calculations.

2016-04-01

Full Text Available This article examines the theoretical viewpoint of quality culture, its formation in industrial plants. Here is discussed cultural ap-proach to quality. It is determined that quality based on a cultural perspective is implemented not only by using tools and methods, but it is the result of cultural factors – exactly the company's values and practices. The values that affect a successful quality culture's integration into entire company's activity are overviewed. This article presents the study of key factors influencing the quality culture's development and it is proposed a conceptual model. The conclusions of performed empirical studies confirm that leadership and company's culture are of paramount im-portance and are the main success factors in developing of the quality culture in the company. The connection between leader-ship and empowerment certifies that each company itself is re-sponsible for the formation of the quality culture.

Full Text Available BACKGROUND Urinary tract infection is very common all over the world and in India more than 10 million cases are reported per year. It is one of the common infections diagnosed in the outpatients as well as the hospitalised patients. Empirical treatment of community acquired urinary tract infections are determined by the antibiotic sensitivity in a population. This study was conducted to determine the antimicrobial sensitivity amongst the uropathogens to help establish local guidelines on treatment of urinary tract infection. MATERIALS AND METHODS In this study, we collected 1306 samples from patients in whom we suspected to have urinary tract infection based on clinical signs and symptoms (e.g. with fever (greater than 38°C without another explanation or from a patient who had at least one urinary symptom (dysuria, urgency, frequency, or suprapubic pain or tenderness in our hospital during January 2016-June 2016. RESULTS Urine cultures were positive for 18% of the patients. Among these cultures, Klebsiella pneumonia (41%, Escherichia coli (35% and Pseudomonas aeruginosa (7% were the common organisms found. Highest antimicrobial sensitivity amongst these pathogens was found with cefoperazone/sulbactam and amikacin. CONCLUSION Cefoperazone/sulbactam and amikacin were the highly sensitive systemic antibiotics while ciprofloxacin and norfloxacin were the sensitive oral antibiotics in our locality.

Sparkling wines produced by traditional method owe their characteristics to secondary fermentation and maturation that occur during a slow ageing in bottles. Yeast autolysis plays an important role during the sparkling wine aging. Using a combination of killer and sensitive yeasts is possible to accelerate yeast autolysis and reduce maturing time. killer and sensitive Saccharomyces cerevisiae strains, separately and in co-cultures, were inoculated in base wine and bottled on pilot-plant scale. Commercial Saccaromyces bayanus strain was also investigated. Protein free amino acid and polysaccharides contents and sensory analysis were determined on the wine samples at 3, 6 and 9 months of aging. Yeast autolysis that occurs during the production of sparkling wines, obtained with co-cultures of killer and sensitive strains, has influenced free amino acids, total protein and polysaccharides content after 3 months aging time: sparkling wines, produced without the use of these yeasts, have reached the same results only after 9 months aging time. These results demonstrate that killer and sensitive yeasts in co-culture can accelerate the onset of autolysis in enological conditions, and has a positive effect on the quality of the aroma and flavor of sparkling wine. This paper offers an interesting biotechnological method to reduce production time of sparkling wine with economical benefits for the producers. We revised all patents relating to sparkling wine considering only those of interest for our study.

This study reports on the development and application of a whole sediment toxicity test using a benthic cladoceran Chydorus sphaericus, as an alternative for the use of pelagic daphnids. A C. sphaericus laboratory culture was started and its performance under control conditions was optimised. The test was firstly validated by determining dose-response relationships for aqueous cadmium and copper and ammonia, showing a sensitivity of C. sphaericus (96 h LC 5 values of 594 μg Cd/L, 191 μg Cu/L and 46 mg ammonia/L at pH 8) similar to that of daphnids. Next, sediment was introduced into the test system and a series of contaminated sediments from polluted locations were tested. A significant negative correlation between survival and toxicant concentrations was observed. It is concluded that the test developed in the present study using the benthic cladoceran C. sphaericus is suitable for routine laboratory sediment toxicity testing. - A test was developed for assaying sediment toxicity using a commonly occurring small-bodied cladoceran

Patient safety culture at healthcare organizations plays an important role in guaranteeing, improving and promoting overall patient safety. Although several conceptual frameworks have been proposed in the past, no standard measurement tool has yet been developed for Japan. In order to examine possibilities to introduce the Hospital Survey on Patient Safety Culture (HSOPS) in Japan, the authors of this study translated the HSOPS into Japanese, and evaluated its factor structure, internal consistency, and construct validity. Healthcare workers (n = 6,395) from 13 acute care general hospitals in Japan participated in this survey. Confirmatory factor analysis indicated that the Japanese HSOPS' 12-factor model was selected as the most pertinent, and showed a sufficiently high standard partial regression coefficient. The internal reliability of the subscale scores was 0.46-0.88. The construct validity of each safety culture sub-dimension was confirmed by polychoric correlation, and by an ordered probit analysis. The results of the present study indicate that the factor structures of the Japanese and the American HSOPS are almost identical, and that the Japanese HSOPS has acceptable levels of internal reliability and construct validity. This shows that the HSOPS can be introduced in Japan.

Full Text Available Trichomonas vaginalis is a flagellate protozoan that lives in the genital tract and causes trichomoniasis in women. About 200 million people all over the world are infected with T. vaginalis. There are various methods with different sensitivity and specificity for detection of this parasite, that one of them is direct smear of vaginal secretions which is simpler, rapid and cheaper than other diagnostic methods. Materials and Methods: Demographic data was gathered by a questionnaire which contained different variables. Vaginal secretions samples were taken by spicolum and two swaps that maintained in glucose solution in separate tubes from 160 women referred to health centers of Khorramabad. One of the vaginal samples was examined by direct smear in saline solution and the other was cultured in Dorse medium. Results: Of 160 women suspected of trichomoniasis, 11.8% and 18.75% were positive by direct smear and culture respectively. The sensitivity of the direct method was 63.3%. Our findings indicated that 30% of the infected women belonged to the 31 – 35 age group, which had the most relative frequency of positive cases. Most of the patients (43% were illiterate or had elementary educational level. Conclussion: The sensivity of direct method is 63% in compare to culture ( as a Gold standard , which is ralatively low . Although the efficacy of this test could be imporved by shortening the elapsed time between sampling and examination , use of skilled microscopists , and different samples , but we recommend that more sensitive methods such as culture and PCR should be used .

Species sensitivity distributions in a context of practical applications for risk-based decisions

Different biological species clearly show different sensitivities to toxic compounds present in their habitat. The absence of differences in sensitivity would entail an 'all nothing' response, with all species responding similarly to pollution. Given the sensitivity variation, however, some species show adverse effects, and others flourish. In this sense, variation is 'music for ecotoxicologists'. But it also is a nuisance: ecotoxicologists need to handle the vast diversity of sensitivities in Ecological Risk Assessment (ERA). This contribution addresses a pragmatic, versatile, statistics-based concept to address species sensitivity differences, and shows options for application. In the 1980s, ecotoxicologists have coined the term 'Species Sensitivity Distributions' (SSDs) for the statistical descriptions that can be applied to address sensitivity variation. An SSD is a Probability Density Function (usually bell-shaped) or Cumulative Distribution Function (sigmoid), that relates the environmental concentration (x) to 'risk' (y). Since their original description and use, the concept was further developed, criticised, and tailored to various policy or assessment problems. (orig.)

Full Text Available AbstractA great deal of research on polymers over the past two decades has been focused on the development of stimuli-responsive polymers to obtain materials able to respond to specific surroundings. In this paper, an overview is presented of the concepts, behavior and applicability of these “smart polymers”. Polymers that are temperature- or pH-sensitive are discussed in detail, including the response mechanisms and types of macromolecules, because they are easy to handle and have a wide range of applications. Finally, the combination of pH and temperature responsive properties by means of graft copolymerization of chitosan with poly (N-isopropylacrylamide (PNIPAM was chosen to represent some synthetic routes and properties of dual-sensitive polymeric systems developed currently.

Full Text Available PROMETHEE is one of methods, which fall into multi-criteria analysis (MCA. The MCA, as the name itself indicates, deals with the evaluation of particular variants according to several criteria. Developed software application (MCA8 for the support of multi-criteria decision-making was upgraded about PROMETHEE method and a graphic tool, which enables the execution of the sensitivity analysis. This analysis is used to ascertain how a given model output depends upon the input parameters. The MCA8 software application with mentioned graphic upgrade was developed for purposes of solving multi-criteria decision tasks. In the MCA8 is possible to perform sensitivity analysis by a simple form – through column graphs. We can change criteria significances (weights in these column graphs directly and watch the changes of the order of variants immediately.

2017-01-01

The extracellular matrix of most natural tissues comprises various types of cells, including fibroblasts, stem cells, and endothelial cells, which communicate with each other directly or indirectly to regulate matrix production and cell functionality. To engineer multicellular interactions in vitro, co-culture systems have achieved tremendous success achieving a more realistic microenvironment of in vivo metabolism than monoculture system in the past several decades. Recently, the fields of tissue engineering and regenerative medicine have primarily focused on three-dimensional co-culture systems using cellular scaffolds, because of their physical and biological relevance to the extracellular matrix of actual tissues. This review discusses several materials and methods to create co-culture systems, including hydrogels, electrospun fibers, microfluidic devices, and patterning for biomimetic co-culture system and their applications for specific tissue regeneration. Consequently, we believe that culture systems with appropriate physical and biochemical properties should be developed, and direct or indirect cell–cell interactions in the remodeled tissue must be considered to obtain an optimal tissue-specific microenvironment.

1991-03-01

PRATOOL is a computer program developed to supplement the Integrated Reliability and Risk Analysis System (IRRAS) probabilistic risk assessment (PRA) computer program. It is intended to be a tool for performing PRA sensitivity analyses. This will allow a PRA's results to be easily reevaluated to show its sensitivity to changing parameter (system, component type, basic event, etc.) values (i.e., failure rates). This report documents a trial application of PRATOOL. It evaluates the sensitivity of core damage frequency to service water system availability at several nuclear power plants. For the purpose of this trail application of PRATOOL, service water system sensitivity studies were performed using the results of several NUREG- 1150 PRAs. These plants were chosen because their PRAs were already loaded into the IRRAS data base. Therefore, they are readily available for this type of study. PRATOOL contains a small subset of the functions provided by IRRAS. The user can select sets of parameters that will act as the bases for sensitivity analyses. Depending on the PRA used, the parameters selected can include: systems, component types, trains, locations, failure modes, and basic events. It will also perform and AND-ing operation on selected parameters. This allows the user define any number of possible combinations of parameters. The results of the four sensitivity studies would tend to indicate that the SWS availability is important for BWRs but unimportant for PWRs. Both BWRs showed significant increases in CDF if their SWS failure rates are allowed to increase. From the results of the four sensitivity studies, it is interesting to note that no improvements made to any of the SWSs' failure rates would result in a significant decrease on CDF. 10 figs

Financial Development and Investment-Cash Flow Sensitivity

Jungwon Suh

2007-06-01

Full Text Available Using firm-level data from thirty-five countries around the world, this paper empirically examines whether investment-cash flow sensitivity reflects financial constraints. Recent US studies have raised questions on the prediction that investment-cash flow sensitivity is a measure of financial constraints. Looking at thirty-five countries with varying degrees of financial development, this study tests whether investment-cash flow sensitivity is in fact related to financial constraints. In most countries, the evidence supporting the argument that firms likely facing financially constraints display high investment-cash flow sensitivity is weak. Moreover, the evidence that firms in the absence of developed financial markets display high investment-cash flow sensitivity is also weak. Overall, the results from this international investigation do not support the prediction that investment-cash flow sensitivity reflects financial constraints.

Compared with the cultured monolayer (2D) cells, three-dimensional (3D) tissue could be more similar to the environment in vivo including the physical support, chemical factors, cell-cell and cell-matrix interaction and so on. With the development of three-dimensional cell culture techniques (TDCC), 3D tissue is widely used in the areas of bystander effect research. This review focuses on introducing the TDCC method and its application in bystander-effect research. First, the development process of 3D tissue culture method was introduced. Secondly, the induction of radiation induced bystander effects both in 2D cell and 3D tissue and its mechanisms were reviewed. Finally, because heavy ion (carbon ion beam) has been developed as a useful tool to cure solid cancer, and the 3D tissue model is an ideal material to study the damages on body after being irradiated and to understand the underlying mechanisms, future study about heavy ion radiation inducing bystander effect in 3D tissue was discussed.

Poliovirus is a recognized surrogate for norovirus, pathogen in water and food, due to the structural and genetic similarity. Although radiation sensitivity of poliovirus in water or media had been reported, there has been no research in food model such as shellfish. In this study, oyster (Crassostrea gigas) was incubated in artificial seawater contaminated with poliovirus, and thus radiation sensitivity of poliovirus was determined in inoculated oyster. The effects of ionizing radiation on the sensitivity of poliovirus were also evaluated under different conditions such as pH (4-7) and salt concentration (1-15%) in culture broth, and temperature during irradiation. The D{sub 10} value of poliovirus in PBS buffer, virus culture broth and oyster was determined to 0.46, 2.84 and 2.94 kGy, respectively. The initial plaque forming unit (PFU) of poliovirus in culture broth was slightly decreased as the decrease of pH and the increase of salt concentration, but radiation sensitivity was not affected by pH and salt contents. However, radiation resistance of poliovirus was increased at frozen state. These results provide the basic information for the inactivation of pathogenic virus in foods by using irradiation.

Poliovirus is a recognized surrogate for norovirus, pathogen in water and food, due to the structural and genetic similarity. Although radiation sensitivity of poliovirus in water or media had been reported, there has been no research in food model such as shellfish. In this study, oyster ( Crassostrea gigas) was incubated in artificial seawater contaminated with poliovirus, and thus radiation sensitivity of poliovirus was determined in inoculated oyster. The effects of ionizing radiation on the sensitivity of poliovirus were also evaluated under different conditions such as pH (4-7) and salt concentration (1-15%) in culture broth, and temperature during irradiation. The D10 value of poliovirus in PBS buffer, virus culture broth and oyster was determined to 0.46, 2.84 and 2.94 kGy, respectively. The initial plaque forming unit (PFU) of poliovirus in culture broth was slightly decreased as the decrease of pH and the increase of salt concentration, but radiation sensitivity was not affected by pH and salt contents. However, radiation resistance of poliovirus was increased at frozen state. These results provide the basic information for the inactivation of pathogenic virus in foods by using irradiation.

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

Culture and Development: A Systematic Relationship.

Science.gov (United States)

Keller, Heidi

2017-09-01

This article argues that the relationships between culture and development are differential and systematic. Therefore the presentation of the Western middle-class developmental pathway in textbooks as universal is grossly neglecting the reality and the psychologies of the majority of the world' s population. First, the conception of culture as the representation of environmental conditions is presented. The level of formal education acts as organizer of social milieus that define different learning environments for children. Mainly two developmental pathways are portrayed: the Western middle-class trajectory and the traditional farmer childhood. Different developmental principles are highlighted, demonstrating systematic cultural differences in the development of a conception of the self: developmental dynamics as exemplified in early mother infant interactions, the timing of developmental milestones emphasizing cultural precocities in motor development and self-recognition, developmental gestalts in different attachment relationships and precursors and consequences demonstrating that different, sometimes contradictory behavioral patterns have the same developmental consequences with the examples of empathy development and autobiographical memory. It is argued that evaluating the development in one pathway with the principles and standards of the other is unscientific and unethical. The recognition of different developmental pathways is a necessity for basic science and a moral obligation for the applied fields.

2015-03-01

Despite a growing recognition of cultural connectedness as an important protective factor for First Nations (FN) peoples' health, there remains a clear need for a conceptual model that organizes, explains, and leads to an understanding of the resiliency mechanisms underlying this concept for FN youth. The current study involved the development of the Cultural Connectedness Scale (CCS) to identify a new scale of cultural connectedness. A sample of 319 FN, Métis, and Inuit youths enrolled in Grades 8-12 from reserve and urban areas in Saskatchewan and Southwestern Ontario, Canada, participated in the current study. A combination of rational expert judgments and empirical data were used to refine the pool of items to a set that is a representative sample of the indicators of the cultural connectedness construct. Exploratory factor analysis (EFA) was used to examine the latent structure of the cultural connectedness items, and a confirmatory factor analysis was used to test the fit of a more parsimonious version of the final EFA model. The resulting 29-item inventory consisted of 3 dimensions: identity, traditions, and spirituality. Criterion validity was demonstrated with cultural connectedness dimensions correlating well with other youth well-being indicators. The conceptualization and operationalization of the cultural connectedness has a number of potential applications both for research and prevention. This study provides an orienting framework that guides measurement of cultural connectedness that researchers need to further explore the role of culture in enhancing resiliency and well-being among FN youth in Canada. 2015 APA, all rights reserved

Suh, Eunkook M

2007-12-01

The self becomes context sensitive in service of the need to belong. When it comes to achieving personal happiness, an identity system that derives its worth and meaning excessively from its social context puts itself in a significantly disadvantageous position. This article integrates empirical findings and ideas from the self, subjective well-being, and cross-cultural literature and tries to offer insights to why East Asian cultural members report surprisingly low levels of happiness. The various cognitive, motivational, behavioral, and affective characteristics of the overly relation-oriented self are discussed as potential explanations. Implications for the study of self and culture are offered.

Nuclear security culture: a generic model for universal application

International Nuclear Information System (INIS)

Khripunov, I.

2005-01-01

Full text: Nuclear security culture found its way into professional parlance several years ago, but still lacks an agreed-upon definition and description. The February 2005 U.S.-Russian Joint Statement, issued at the presidential summit meeting in Bratislava, referred specifically to security culture, focusing renewed attention on the concept. Numerous speakers at the March 2005 International Atomic Energy Agency's (IAEA) international conference on nuclear security referred to security culture, but their visions and interpretations were often at odds with one another. Clearly, there is a need for a generic model of nuclear security culture with universal applicability. Internationally acceptable standards in this area would be invaluable for evaluation, comparison, cooperation, and assistance. They would also help international bodies better manage their relations with the nuclear sectors in various countries. This paper will develop such a model. It will use the IAEA definition of nuclear security, and then apply Edgar Schein's model of organizational culture to security culture at a generic nuclear facility. A cultural approach to physical protection involves determining what attitudes and beliefs need to be established in an organization, how these attitudes and beliefs manifest themselves in the behavior of assigned personnel, and how desirable attitudes and beliefs can be transcribed into formal working methods to produce good outcomes, i.e., effective protection. The security-culture mechanism I will propose is broken into four major units: facility leadership, proactive policies and procedures, personnel performance, and learning and professional improvement. The paper will amplify on the specific traits characteristic of each of these units. Security culture is not a panacea. In a time of mounting terrorist threats, it should nonetheless be looked upon as a necessary organizational tool that enhances the skills of nuclear personnel and ensures that

Development of Safety Culture Indicators for HANARO

International Nuclear Information System (INIS)

Wu, Jong-Sup; Lee, Kye-Hong

2007-01-01

Safety culture is more important than a technical matter for the management of nuclear facilities. Some of the accidents that have occurred recently in nuclear plants are important as a social problem besides a technical problem. That's why the management of nuclear plants has been focused on the safety culture to improve confidence of nuclear facilities. As for a safety culture, there are difficulties in that a tangible result does not come out clearly in spite of an effort for a long time. Some IAEA guides and reports about a safety culture and its evaluation method for nuclear power plants (NPP) were published after the Chernobyl accident. Until now there is no tool to evaluate a safety culture of for research reactors. HANARO developed its own safety culture indicators based on the IAEA's documents. The purpose of the development of the safety culture indicators is to evaluate and enhance the safety attitude in HANARO

Surbone, Antonella

2008-03-01

Cultural competence in oncology requires the acquisition of specific knowledge, clinical skills, and attitudes that facilitate effective cross-cultural negotiation in the clinical setting, thus, leading to improved therapeutic outcomes and decreased disparities in cancer care. Cultural competence in oncology entails a basic knowledge of different cultural attitudes and practices of communication of the truth and of decision-making styles throughout the world. Cultural competence always presupposes oncology professionals' awareness of their own cultural beliefs and values. To be able to communicate with cancer patients in culturally sensitive ways, oncologists should have knowledge of the concept of culture in its complexity and of the risks of racism, classism, sexism, ageism, and stereotyping that must be avoided in clinical practice. Oncologists should develop a sense of appreciation for differences in health care values, based on the recognition that no culture can claim hegemony over others and that cultures are evolving under their reciprocal influence on each other. Medical schools and oncology training can teach communication skills and cultural competence, while fostering in all students and young doctors those attitudes of humility, empathy, curiosity, respect, sensitivity, and awareness that are needed to deliver effective and culturally sensitive cancer care.

Cultural Diversity Training: The Necessity of Cultural Competence for Health Care Providers and in Nursing Practice.

Young, Susan; Guo, Kristina L

2016-01-01

The purpose of this article is to discuss the need to provide culturally sensitive care to the growing number of diverse health care consumers. A literature review of national standards and research on cultural competency was conducted and specifically focused on the field of nursing. This study supports the theory that cultural competence is learned over time and is a process of inner reflection and awareness. The domains of awareness, skill, and knowledge are essential competencies that must be gained by health care providers and especially for nurses. Although barriers to providing culturally sensitive care exist, gaining a better understanding of cultural competence is essential to developing realistic education and training techniques, which will lead to quality professional nursing practice for increasingly diverse populations.

Phase sensitive spectral domain interferometry for label free biomolecular interaction analysis and biosensing applications

Science.gov (United States)

Chirvi, Sajal

Biomolecular interaction analysis (BIA) plays vital role in wide variety of fields, which include biomedical research, pharmaceutical industry, medical diagnostics, and biotechnology industry. Study and quantification of interactions between natural biomolecules (proteins, enzymes, DNA) and artificially synthesized molecules (drugs) is routinely done using various labeled and label-free BIA techniques. Labeled BIA (Chemiluminescence, Fluorescence, Radioactive) techniques suffer from steric hindrance of labels on interaction site, difficulty of attaching labels to molecules, higher cost and time of assay development. Label free techniques with real time detection capabilities have demonstrated advantages over traditional labeled techniques. The gold standard for label free BIA is surface Plasmon resonance (SPR) that detects and quantifies the changes in refractive index of the ligand-analyte complex molecule with high sensitivity. Although SPR is a highly sensitive BIA technique, it requires custom-made sensor chips and is not well suited for highly multiplexed BIA required in high throughput applications. Moreover implementation of SPR on various biosensing platforms is limited. In this research work spectral domain phase sensitive interferometry (SD-PSI) has been developed for label-free BIA and biosensing applications to address limitations of SPR and other label free techniques. One distinct advantage of SD-PSI compared to other label-free techniques is that it does not require use of custom fabricated biosensor substrates. Laboratory grade, off-the-shelf glass or plastic substrates of suitable thickness with proper surface functionalization are used as biosensor chips. SD-PSI is tested on four separate BIA and biosensing platforms, which include multi-well plate, flow cell, fiber probe with integrated optics and fiber tip biosensor. Sensitivity of 33 ng/ml for anti-IgG is achieved using multi-well platform. Principle of coherence multiplexing for multi

Full Text Available Knowledge has become a key resource and the driver of economic progress. The distribution of welfare in the world demonstrates that the richest countries are the ones that have the knowledge, not natural resources. Creating a knowledge-based society is the foundation for sustainable development. Key factors influencing the creation of a knowledge-based economy are investments in education, research and development and application of new technologies. Nevertheless, culture, attitudes and values that affect people’s commitment to continuous improvement and learning, can also play an important role in creating a knowledge society for sustainable development. In this paper authors are making an attempt to identify the basic values of employees in several Serbian companies by means of factor analysis approach, with special emphasis on the national cultural dimensions framework and its utility.

Singularity-sensitive gauge-based radar rainfall adjustment methods for urban hydrological applications

Directory of Open Access Journals (Sweden)

L.-P. Wang

2015-09-01

Full Text Available Gauge-based radar rainfall adjustment techniques have been widely used to improve the applicability of radar rainfall estimates to large-scale hydrological modelling. However, their use for urban hydrological applications is limited as they were mostly developed based upon Gaussian approximations and therefore tend to smooth off so-called "singularities" (features of a non-Gaussian field that can be observed in the fine-scale rainfall structure. Overlooking the singularities could be critical, given that their distribution is highly consistent with that of local extreme magnitudes. This deficiency may cause large errors in the subsequent urban hydrological modelling. To address this limitation and improve the applicability of adjustment techniques at urban scales, a method is proposed herein which incorporates a local singularity analysis into existing adjustment techniques and allows the preservation of the singularity structures throughout the adjustment process. In this paper the proposed singularity analysis is incorporated into the Bayesian merging technique and the performance of the resulting singularity-sensitive method is compared with that of the original Bayesian (non singularity-sensitive technique and the commonly used mean field bias adjustment. This test is conducted using as case study four storm events observed in the Portobello catchment (53 km2 (Edinburgh, UK during 2011 and for which radar estimates, dense rain gauge and sewer flow records, as well as a recently calibrated urban drainage model were available. The results suggest that, in general, the proposed singularity-sensitive method can effectively preserve the non-normality in local rainfall structure, while retaining the ability of the original adjustment techniques to generate nearly unbiased estimates. Moreover, the ability of the singularity-sensitive technique to preserve the non-normality in rainfall estimates often leads to better reproduction of the urban

Contemporary Approaches to Safety Culture: Lessons from Developing a Regulatory Oversight Approach

International Nuclear Information System (INIS)

Goebel, V.; Heppell-Masys, K.

2016-01-01

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

Safety culture assessment developed by JANTI

International Nuclear Information System (INIS)

Hamada, Jun

2009-01-01

Japan's JCO accident in September 1999 provided a real-life example of what can happen when insufficient attention is paid to safety culture. This accident brought to light the importance of safety culture and reinforced the movement to foster a safety culture. Despite this, accidents and inappropriate conduct have continued to occur. Therefore, there is a strong demand to instill a safety culture throughout the nuclear power industry. In this context, Japan's nuclear power regulator, the Nuclear and Industrial Safety Agency (NISA), decided to include in its safety inspections assessments of the safety culture found in power utilities' routine safety operations to get signs of deterioration in the organizational climate. In 2007, NISA constructed guidelines for their inspectors to carry out these assessments. At the same time, utilities have embarked on their own independent safety culture initiatives, such as revising their technical specifications and building effective PDCA cycle to promote safety culture. In concert with these developments, JANTI has also instituted safety culture assessments. (author)

The importance of cultural competency in general pediatrics.

Brotanek, Jane M; Seeley, Christina E; Flores, Glenn

2008-12-01

There is a growing awareness of the importance of cultural competency in pediatrics. The authors review the most recent studies that examine the impact of cultural competency on general pediatric care, explore cultural beliefs and practices affecting clinical care, and describe culturally sensitive interventions designed to address racial/ethnic health disparities. The beneficial effects of cultural competency embrace health outcomes, quality of care, and patient satisfaction, while failure to consider language and culture can have serious adverse consequences for clinical care, including patient safety and healthcare access. A five-component model of cultural competency has been developed, and a growing literature details an array of normative cultural values, folk illnesses, parent beliefs/practices, and provider behaviors that can have a profound impact on pediatric care. Culturally sensitive interventions are being developed to lessen racial/ethnic health disparities. A goal for the pediatrician is to provide culturally competent healthcare by using trained medical interpreters with limited English-proficient families, being familiar with normative cultural values that affect the healthcare of commonly encountered racial/ethnic groups, and asking about folk illness beliefs and ethnomedical treatments.

A Global Sensitivity Analysis Methodology for Multi-physics Applications

Energy Technology Data Exchange (ETDEWEB)

Tong, C H; Graziani, F R

2007-02-02

Experiments are conducted to draw inferences about an entire ensemble based on a selected number of observations. This applies to both physical experiments as well as computer experiments, the latter of which are performed by running the simulation models at different input configurations and analyzing the output responses. Computer experiments are instrumental in enabling model analyses such as uncertainty quantification and sensitivity analysis. This report focuses on a global sensitivity analysis methodology that relies on a divide-and-conquer strategy and uses intelligent computer experiments. The objective is to assess qualitatively and/or quantitatively how the variabilities of simulation output responses can be accounted for by input variabilities. We address global sensitivity analysis in three aspects: methodology, sampling/analysis strategies, and an implementation framework. The methodology consists of three major steps: (1) construct credible input ranges; (2) perform a parameter screening study; and (3) perform a quantitative sensitivity analysis on a reduced set of parameters. Once identified, research effort should be directed to the most sensitive parameters to reduce their uncertainty bounds. This process is repeated with tightened uncertainty bounds for the sensitive parameters until the output uncertainties become acceptable. To accommodate the needs of multi-physics application, this methodology should be recursively applied to individual physics modules. The methodology is also distinguished by an efficient technique for computing parameter interactions. Details for each step will be given using simple examples. Numerical results on large scale multi-physics applications will be available in another report. Computational techniques targeted for this methodology have been implemented in a software package called PSUADE.

Introduction: In spite of the discovery of viral culture technology about a century ago, its application in diagnostic labs is being used since 1970s. It served as the "gold standard" for virus detection for long. In recent years, rapid, technically less challenging, sensitive and highly specific viral identification is possible by molecular tools. Hence, the purpose of this study was to analyze the importance of real time PCR over virus culture in diagnosis of Influenza virus infections, the...

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)

A wide variety of nanobiotechnologic applications are being developed for nanoparticle based in vitro diagnostic and imaging systems. Some of these systems make possible highly sensitive detection of molecular biomarkers. Frequently, the very low concentration of the biomarkers makes impossible the classical, partial differential equation-based mathematical simulation of the motion of the nanoparticles involved. We present a three-dimensional Brownian motion simulation tool for the prediction of the movement of nanoparticles in various thermal, viscosity, and geometric settings in a rectangular cuvette.

Aerospace applications require the development of chemical sensors with capabilities beyond those of commercially available sensors. In particular, factors such as minimal sensor size, weight, and power consumption are particularly important. Development areas which have potential aerospace applications include launch vehicle leak detection, engine health monitoring, fire detection, and environmental monitoring. Sensor development for these applications is based on progress in three types of technology: 1) Micromachining and microfabrication (Microsystem) technology to fabricate miniaturized sensors. 2) The use of nanocrystalline materials to develop sensors with improved stability combined with higher sensitivity. 3) The development of high temperature semiconductors, especially silicon carbide. However, due to issues of selectivity and cross-sensitivity, individual sensors are limited in the amount of information that they can provide in environments that contain multiple chemical species. Thus, sensor arrays are being developed to address detection needs in such multi-species environments. This paper discusses the needs of space applications as well as the point-contact sensor technology and sensor arrays being developed to address these needs. Sensors to measure hydrogen, hydrocarbons, hydrazine, nitrogen oxides (NO,), carbon monoxide, oxygen, and carbon dioxide are being developed as well as arrays for leak, fire, and emissions detection. Demonstrations of the technology will also be discussed. It is concluded that microfabricated sensor technology has significant potential for use in a range of aerospace applications.

Full Text Available The isolation of arboviruses from patient's low titer sera can be difficult. Here we compared the detection efficiency of Dengue (DEN, Yellow Fever (YF, Saint Louis Encephalitis (SLE, West Nile (WN, Ilheus (ILH, Group C (GC, Oropouche (ORO, Mayaro (MAY and Venezuela Encephalitis Equine (VEE viruses using a Modified Shell Vial Culture (MSVC protocol to a Standard Cell Culture (SCC protocol. First the MSVC and SCC protocols were compared using five dilutions for each of the following stock viruses: DEN-1, DEN-2, DEN-3, DEN-4, YF, SLE, WN, ILH, GC, ORO, MAY and VEE. Next, patients' original sera from which viruses (DEN-1, DEN-2, DEN-3, YF, GC, ORO, MAY and VEE had been previously isolated were compare by the two methods using five sera dilutions. In addition, seven sera that were positive for DEN-3 by RT-PCR and negative by SCC were processed by MSVC. The MSVC protocol was consistently 1-2 logs higher virus dilution more sensitive for virus detection than the SCC protocol for all stock Flaviviruses tested (DEN-1, DEN-2, DEN-3, DEN-4, YF, SLE, WN and ILH. MSVC was equal to or one log more sensitive for virus detection than SCC for the stock Bunyaviruses (GC and ORO. For the stock Alphavirus MAY, MSVC was equally or one log more sensitive for virus detection than SCC, while for VEE SCC was equally or one log more sensitive for virus detection than MSVC. MSVC was consistently one to two sera dilutions more sensitive than SCC for the detection of Flaviviruses from patients' sera. Both methods were approximately equally sensitive for the detection of Bunyaviruses from patients' sera and equal or one dilution less sensitive for the detection of Alphaviruses from patients' sera. Additionally, MSVC detected DEN virus in five of seven DEN-3 RT-PCR positive, SCC negative patients' sera.

Is there a genetic contribution to cultural differences? Collectivism, individualism and genetic markers of social sensitivity.

Science.gov (United States)

Way, Baldwin M; Lieberman, Matthew D

2010-06-01

Genes and culture are often thought of as opposite ends of the nature-nurture spectrum, but here we examine possible interactions. Genetic association studies suggest that variation within the genes of central neurotransmitter systems, particularly the serotonin (5-HTTLPR, MAOA-uVNTR) and opioid (OPRM1 A118G), are associated with individual differences in social sensitivity, which reflects the degree of emotional responsivity to social events and experiences. Here, we review recent work that has demonstrated a robust cross-national correlation between the relative frequency of variants in these genes and the relative degree of individualism-collectivism in each population, suggesting that collectivism may have developed and persisted in populations with a high proportion of putative social sensitivity alleles because it was more compatible with such groups. Consistent with this notion, there was a correlation between the relative proportion of these alleles and lifetime prevalence of major depression across nations. The relationship between allele frequency and depression was partially mediated by individualism-collectivism, suggesting that reduced levels of depression in populations with a high proportion of social sensitivity alleles is due to greater collectivism. These results indicate that genetic variation may interact with ecological and social factors to influence psychocultural differences.

Cultural Challenges in Developing E-Learning Content

Directory of Open Access Journals (Sweden)

Marianne Amir Azer

2011-03-01

Full Text Available Education is an important component of any nation’s development process. Society has been credited with creating technology, but technology is simultaneously creating society. One of the key benefits of such technology creation includes learning and curriculum development, which is otherwise referred to as e-leaning, and more appropriately referred to as global e-learning. Global e-learning raises some implications, which include communication, culture, and technology, that must be addressed before successful implementation and outcome can occur. In this paper, we discuss cultural related issues such as culture influence on e-learning and the dimensions of cultural variability. In addition, we present the main challenges to provide e-learning opportunities. Finally, a case study for facing the cultural challenges is presented; this will be followed by concluding remarks at the end of this paper.

The new issue (no. 11) of the IAEA publications series Safety Reports, devoted to the safety culture in nuclear engineering Safety culture development in the nuclear activities. Practical recommendations to achieve success, is analyzed. A number of recommendations of international experts is presented and basic general indicators of satisfactory and insufficient safety culture in the nuclear engineering are indicated. It is shown that the safety culture has two foundations: human behavior and high quality of the control system. The necessity of creating the confidence by the management at all levels of the enterprise, development of individual initiative and responsibility of the workers, which make it possible to realize the structural hierarchic system, including technical, human and organizational constituents, is noted. Three stages are traced in the process of introducing the safety culture. At the first stage the require,emts of scientific-technical documentation and provisions of the governmental, regional and control organs are fulfilled. At the second stage the management of the organization accepts the safety as an important direction in its activities. At the third stage the organization accomplishes its work, proceeding from the position of constant safety improvement. The general model of the safety culture development is considered [ru

Developing Sensitivity Indicators for Hydraulic Perturbation

M.M. Heidari

2016-02-01

Full Text Available Introduction: Determination the hydraulic performance of an irrigation network requires adequate knowledge about the sensitivities of the network structures. Hydraulic sensitivity concept of structures and channel reaches aid network operators in identifying structures with higher sensitivities which will attract more attention both during network operation and maintenance program. Sluice gates are frequently used as regulator and delivery structures in irrigation networks. Usually discharge coefficient of sluice gate is considered constant in the design and operation stage. Investigation of sensitivity of offtakes and cross-regulators has carried out by various researchers and some hydraulic sensitivity indicators have been developed. In the previous researches, these indexes were developed based on constant coefficient of discharge for free flow sluice gates. However, the coefficient of discharge for free flow sluice gates depend on gate opening and the upstream water depth. So, in this research, some hydraulic sensitivity indicators at structure based on variable coefficient of discharge for free flow sluice gates were developed and they were validated by using observed data. Materials and Methods: An experimental setup was constructed to analyses the performance of the some hydraulic sensitivity. The flume was provided with storage reservoir, pumps, electromagnetic flowmeter, entrance tank, feeder canal, delivery canals, offtakes, cross-regulators, collector reservoir, piezometric boards. The flume is 60.5 m long and the depth of that is 0.25 m, of which only a small part close to offtake and Cross-regulators was needed for these tests. Offtakes and Cross-regulators are free-flowing sluice gates type. Offtakes were located at distances 20 m and 42.5 m downstream from the entrance tank, respectively. and, Cross-regulators were located 2 m downstream from each offtakes. The offtakes are 0.21 m and Cross-regulators are 0.29 m wide. The upstream

Studies of the primary cultures of granulocytes, mononuclear, and monocyte-macrophage cells derived from human blood were performed using variola virus (VARV) in the doses of 0.001-0.021 PFU/cell (plaques-forming units per cell). Positive dynamics of the virus accumulation was observed only in the monocyte-macrophages with maximum values of virus concentration (5.0-5.5 Ig PFU/ml) mainly within six days after the infection. The fact of VARV replication in the monocyte-macrophages was confirmed by the data of electron microscopy. At the same time, virus vaccines when tested in doses 3.3 and 4.2 Ig PFU/ml did not show the ability to reproduce in these human cells. The people sensitivity to VARV as assessed from the data obtained on human monocyte-macrophages corresponded to -1 PFU (taking into account the smooth interaction of the virus in the body to the cells of this type), which is consistent to previously found theoretical data on the virus sensitivity. The human susceptibility to VARV assessed experimentally can be used to predict the adequacy of developed smallpox models (in vivo) based on susceptible animals. This is necessary for reliable assessment of the efficiency of development of drugs for treatment and prophylaxis of the smallpox.

Highlights: • Position-sensitive detectors were developed for storage-ring decay spectroscopy. • Fiber scintillation and silicon strip detectors were tested with heavy ion beams. • A new fiber scintillation detector showed an excellent position resolution. • Position and energy detection by silicon strip detectors enable full identification. -- Abstract: As next generation spectroscopic tools, heavy-ion cooler storage rings will be a unique application of highly charged RI beam experiments. Decay spectroscopy of highly charged rare isotopes provides us important information relevant to the stellar conditions, such as for the s- and r-process nucleosynthesis. In-ring decay products of highly charged RI will be momentum-analyzed and reach a position-sensitive detector set-up located outside of the storage orbit. To realize such in-ring decay experiments, we have developed and tested two types of high-resolution position-sensitive detectors: silicon strips and scintillating fibers. The beam test experiments resulted in excellent position resolutions for both detectors, which will be available for future storage-ring experiments

Microscopic examination of eggs of parasitic helminths in stool samples has been the most widely used classical diagnostic method for infections, but tiny and low numbers of eggs in stool samples often hamper diagnosis of helminthic infections with classical microscopic examination. Moreover, it is also difficult to differentiate parasite eggs by the classical method, if they have similar morphological characteristics. In this study, we developed a rapid and sensitive polymerase chain reaction (PCR)-based molecular diagnostic method for detection of Clonorchis sinensis eggs in stool samples. Nine primers were designed based on the long-terminal repeat (LTR) of C. sinensis retrotransposon1 (CsRn1) gene, and seven PCR primer sets were paired. Polymerase chain reaction with each primer pair produced specific amplicons for C. sinensis, but not for other trematodes including Metagonimus yokogawai and Paragonimus westermani. Particularly, three primer sets were able to detect 10 C. sinensis eggs and were applicable to amplify specific amplicons from DNA samples purified from stool of C. sinensis-infected patients. This PCR method could be useful for diagnosis of C. sinensis infections in human stool samples with a high level of specificity and sensitivity. PMID:23916334

We live in an age when education is being internationalized. This can confront students with 'cultural hegemony' that can result from the unequal distribution of power and privilege in global society. The name that is given to awareness of social inequality is 'critical consciousness'. Cross-cultural dialogue provides an opportunity for learners to develop critical consciousness to counter cultural hegemony. The purpose of this research was to understand how learners engage with cross-cultural dialogue, so we can help them do so more effectively in the future. The setting for this research was an online discussion in an international health professions educator fellowship program. We introduced scenarios with cultural references to study the reaction of participants to cultural conversation cues. We used an inductive thematic analysis to explore power and hegemony issues. Participants reflected that personally they were more likely to take part in cross-cultural discussions if they recognized the context discussed or had prior exposure to educational settings with cultural diversity. They identified barriers as lack of skills in facilitating cross-cultural discussions and fear of offending others. They suggested deliberately introducing cultural issues throughout the curriculum. Our results indicate that developing critical consciousness and cross-cultural competency will require instructional design to identify longitudinal opportunities to bring up cross-cultural issues, and training facilitators to foster cross-cultural discussions by asking clarifying questions and navigating crucial/sensitive conversations.

This study identified, mapped and treated the clinical features of mentally ill people, who had been isolated and restrained by family and community members as a result of a functional failure of the traditional medical, hospital-based mental health model currently practiced in Indonesia. A 10-month epidemiological population survey was carried out in Karangasem regency of Bali, Indonesia. A total of 404,591 individuals were clinically interviewed, of which 895 individuals with mental health problems were identified, with 23 satisfying criteria of physical restraint and confinement. Of the latter, twenty were males; age range was 19-69 years, all diagnosed by the researchers with schizophrenia-spectrum disorder (ICD-10 diagnostic criteria). Duration of restraint ranged from 3 months to 30 years (mean = 8.1 years, SD = 8.3 years). Through the application of a holistic intervention model, all patients exhibited a remarkable recovery within 19 months of treatment. We conclude that the development of a community-based, culturally sensitive and respectful mental health model can serve as an optimum promoter of positive mental health outcomes.

In recent times, health care professionals (HCP) have come across a number of migrants as their patients. The cultural differences lead to communicational challenges between the migrant patients and health care professionals. Our project aimed to discover HCPs' attitudes, challenges and needs on cross-cultural communication, so that we can develop an e-learning solution that would be helpful for them. By conducting interviews with HCPs, we identified five crucial categories of problems and the current solutions that experienced professionals use to tackle those problems. These interviews also helped us in understanding the motivational factors of HCPs, when using e-learning application. Health care professionals prefer a focus on examples and themes such as death and pain that they face in their everyday work. Changing attitudes by e-learning application is challenging. However, e-learning was recognized as a flexible way for supporting traditional training with HCPs who are busy at work most of the time.

Full Text Available Writing is considered to be the most demanding and difficult skill for many college students, since there are some steps to be followed such as prewriting, drafting, editing, revising and publishing. The interesting topic like culture including lifestyle, costume, and custom is necessary to be offered in Academic Writing class. Accordingly, this article aims to elaborate the application of a cultural project based learning to develop students’ ability in academic writing. This descriptive qualitative research was conducted in Academic Writing class consisting of 20 students of the fourth semester. The students were divided into some groups, each consisting of 4-5 people assigned to make a cultural project within 6 weeks, in the form of essay. Each member of the groups has to create his/ her own essay and then compile the essays to be a mini-journal. Therefore, one group has one mini-journal consisting of 4-5 essays. To check the content of mini-journal, the lecturer also asked the groups to present in front of the class to get some suggestions, feedback, or comments.

As the population demographics for the United States (U.S.) shift towards increasing diversity, it is essential that nurses provide culturally competent care. Cultural sensitivity has been identified as a major curricular element in the American Association of Colleges of Nursing's (AACN) The Essentials of Baccalaureate Education for Professional Nursing Practice. Thus it is imperative that nursing faculty use effective strategies to help nursing students develop cultural sensitivity and competence. Educational workshops focusing on cultural diversity are usually designed to increase people's cultural sensitivity. The purpose of this study was to assess the effectiveness of a cultural diversity forum on nursing students' cultural sensitivity as measured by their openness to diversity. A convenience sample of students was recruited from a public university in the southeastern United States. The workshop was designed as a forum that combined a keynote presentation, shared meal, and a small group interactional activity. Cultural sensitivity was measured using the Openness to Diversity/Challenge Scale (ODCS), and was administered to students before and after the forum. A convenience sample of 47 students agreed to participate and completed both the pretest and posttest. Following the workshop, the students had more cultural sensitivity as measured by their scores on the ODCS (Wilcoxin Signed-Rank test z= -3.286, p = 0.001). The findings suggested that an educational format like the cultural diversity forum can promote students' cultural sensitivity. Further research needs to continue to focus on the effectiveness of strategies to increase the cultural sensitivity of baccalaureate nursing students.

Medical schools worldwide are increasingly switching to student-centred methods such as problem-based learning (PBL) to foster lifelong self-directed learning (SDL). The cross-cultural applicability of these methods has been questioned because of their Western origins and because education contexts and learning approaches differ across cultures. This study evaluated PBL's cross-cultural applicability by investigating how it is applied in three medical schools in regions with different cultures in, respectively, East Asia, the Middle East and Western Europe. Specifically, it investigated how students' cultural backgrounds impact on SDL in PBL and how this impact affects students. A qualitative, cross-cultural, comparative case study was conducted in three medical schools. Data were collected through 88 semi-structured, in-depth interviews with Year 1 and 3 students, tutors and key persons involved in PBL, 32 observations of Year 1 and 3 PBL tutorials, document analysis, and contextual information. The data were thematically analysed using the template analysis method. Comparisons were made among the three medical schools and between Year 1 and 3 students across and within the schools. The cultural factors of uncertainty and tradition posed a challenge to Middle Eastern students' SDL. Hierarchy posed a challenge to Asian students and achievement impacted on both sets of non-Western students. These factors were less applicable to European students, although the latter did experience some challenges. Several contextual factors inhibited or enhanced SDL across the cases. As students grew used to PBL, SDL skills increased across the cases, albeit to different degrees. Although cultural factors can pose a challenge to the application of PBL in non-Western settings, it appears that PBL can be applied in different cultural contexts. However, its globalisation does not postulate uniform processes and outcomes, and culturally sensitive alternatives might be developed. �

The purpose of this study was to develop and cross-culturally validate the Korean version of SMArtphone's uSability Heuristics (K-SMASH). In the study, it was used the adaptation process consisted of five stages, namely, translation, synthesis, back translation, expert committee review, and pretesting. In the pretesting stage, a mobile application, using the prefinal K-SMASH, was evaluated for the severity of usability problems by three experts in computer science and informatics. Each participant completed the evaluation and was interviewed about their understanding, interpretation, and opinion of the cultural relevance of the prefinal K-SMASH. Next, we reviewed the differences in the experts' opinions and the questionnaire results. Twelve SMASH items, words and sentences, were translated, back translated, and revised, considering the conceptual meaning in the context of the Korean culture, by experts in various fields, including a Korean linguist and a bilingual translator, through the first stage to the fourth stage. In the pretesting stage, the results showed no major differences among the severity ratings of participants. Furthermore, all participants answered that there were no critical discrepancies or inconsistencies with the cultural relevance of the prefinal K-SMASH. The results of the study provide preliminary evidence that the modified K-SMASH can be used for heuristic evaluation, one of the usability tests, when developing applications in Korea.

The following critique discusses a few concerns and three major shortcomings of the paper, including skewed sample frame and incorrect choice of countries for assessing cross-national applicability of the scale, not discussing the differences in the means of the seven distinct dimensions of AGCC across the four nations studied by the authors, and absence of any critical review of existing consumer acculturation scales vis-à-vis AGCC. © The Author(s) 2016.

How commercial and ``violent'' video games can promote culturally sensitive science learning: some questions and challenges

Science.gov (United States)

Kwah, Helen

2012-12-01

In their paper, Muñoz and El-Hani propose to bring video games into science classrooms to promote culturally sensitive ethics and citizenship education. Instead of bringing "educational" games, Muñoz and El-Hani take a more creative route and include games such as Fallout 3® precisely because they are popular and they reproduce ideological and violent representations of gender, race, class, nationality, science and technology. However, there are many questions that arise in bringing these commercial video games into science classrooms, including the questions of how students' capacities for critical reflection can be facilitated, whether traditional science teachers can take on the role of using such games in their classrooms, and which video games would be most appropriate to use. In this response, I raise these questions and consider some of the challenges in order to further the possibility of implementing Muñoz and El-Hani's creative proposal for generating culturally sensitive science classrooms.

Full Text Available Background: We live in an age when education is being internationalized. This can confront students with ‘cultural hegemony’ that can result from the unequal distribution of power and privilege in global society. The name that is given to awareness of social inequality is ‘critical consciousness’. Cross-cultural dialogue provides an opportunity for learners to develop critical consciousness to counter cultural hegemony. The purpose of this research was to understand how learners engage with cross-cultural dialogue, so we can help them do so more effectively in the future. Method: The setting for this research was an online discussion in an international health professions educator fellowship program. We introduced scenarios with cultural references to study the reaction of participants to cultural conversation cues. We used an inductive thematic analysis to explore power and hegemony issues. Results: Participants reflected that personally they were more likely to take part in cross-cultural discussions if they recognized the context discussed or had prior exposure to educational settings with cultural diversity. They identified barriers as lack of skills in facilitating cross-cultural discussions and fear of offending others. They suggested deliberately introducing cultural issues throughout the curriculum. Conclusion: Our results indicate that developing critical consciousness and cross-cultural competency will require instructional design to identify longitudinal opportunities to bring up cross-cultural issues, and training facilitators to foster cross-cultural discussions by asking clarifying questions and navigating crucial/sensitive conversations.

Full Text Available Culture has a critical role in transforming localities into more attractive places to work and invest. Cultural activities and facilities significantly affect the development of the physical environment of cities. But what does it all mean for the local residents of the neighbourhoods? How do they feel or participate in cultural activities organized for them? The overall aim of this study has been to evaluate participation effect on the development of Riga’s neighbourhoods during the year of The European Capital of Culture. During the research, the authors have used the mixed research methodology. The qualitative analysis of the Riga 2014 programme has been done based on the qualitative interviews with the artistic team, project managers and entrepreneurs from Riga’s neighbourhoods; besides, a detailed analysis of Riga 2014 programme events has been performed. The main findings show that cultural life in the neighbourhoods is among the most important factors determining the satisfaction with life by the neighbourhoods’ inhabitants. Personalities, not infrastructure have a crucial importance in the development of neighbourhood cultural life. Cultural activities in neighbourhood should be carried out in close cooperation with the stakeholders from different sectors. This can bring to sustainable and long‑term effects.

Full Text Available While a precise forecast for the next decades is clearly impossible, some major challenges that need to be addressed in the next 10-20 years can be identified. Technologically there will be a shift from Information and Communication Technologies (ICT to Universal Convergence Technologies (UCT. In the cultural realm, these challenges include problems of repositories, the changing scope of cultural heritage; new links between national, regional and local; between culture, knowledge and scholarship; approaches to intellectual property and to models of culture. Five dangers are outlined, namely, over-zealous commercialism; anti-technology among scholars, anti-universal narratives; forgetting the past and a systematic destruction of memory. The need for a permanent E-Culture Net is outlined which would a address these challenges; b develop critical methods; c create new models of culture that transcend Euro-Centric visions and d focus on a Distributed European Electronic Resource (DEER.The American vision of the Internet remains focusses largely on uni-lingual e-commerce. By contrast, the European vision, through its links with tourism, clearly has financial dimensions, and at the same time is developing a multi-lingual approach to cultural heritage that includes historical and cultural dimensions. This vision extends beyond culture to new definitions of knowledge. While the rhetoric of the day may focus on profit schedules for the next quarter, it is important to recall that major changes in new media have much longer cycles entailing decades and even centuries before their full effects are appreciated.

The research has been focused to design, fabricate, and develop high temperature/high sensitivity novel multifunctional chemical sensors for the selective detection of fossil energy gases used in power and fuel systems. By systematically studying the physical properties of the LnBaCo₂O_5+d (LBCO) [Ln=Pr or La] thin-films, a new concept chemical sensor based high temperature chemical resistant change has been developed for the application for the next generation highly efficient and near zero emission power generation technologies. We also discovered that the superfast chemical dynamic behavior and an ultrafast surface exchange kinetics in the highly epitaxial LBCO thin films. Furthermore, our research indicates that hydrogen can superfast diffuse in the ordered oxygen vacancy structures in the highly epitaxial LBCO thin films, which suggest that the LBCO thin film not only can be an excellent candidate for the fabrication of high temperature ultra sensitive chemical sensors and control systems for power and fuel monitoring systems, but also can be an excellent candidate for the low temperature solid oxide fuel cell anode and cathode materials.

Schuessler, Jenny B; Wilder, Barbara; Byrd, Linda W

2012-01-01

Cultural humility requires self-evaluation and the awareness that one's own culture is not the only or best one. Teaching health care providers to become culturally humble includes the development of critical thinking skills and the ability to reflect on practice. Journaling as a teaching strategy helps students develop these skills. This article describes the use of reflective journaling as students progressed through four semesters of a community clinical experience. This qualitative, descriptive study was based on the principles of naturalistic inquiry with person-centered written reflections.Two hundred journal entries from 50 students were reviewed, and II themes were identified. Cultural humility cannot be learned merely in the classroom with traditional teaching methods. Reflection on experiences over time leads to the development of cultural humility.

High cell density cultures produced by internal retention: application in continuous ethanol fermentation

Berta Carola Pérez

2004-07-01

Full Text Available Ethanol has provoked great interest due to its potential as an alternative fuel. Nevertheless, fermentation processes must be developed by increasing the low volumetric productivity achieved in conventional cultures (batch or continuous to make this product become economically competitive. This can be achieved by using techniques leading to high cell concentration and reducing inhibition by the end-product. One of the frequently employed methods involves cell recycling. This work thus developed a membrane reactor incorporating a filtration module with 5 u,m stainless steel tubular units inside a 3L stirred jar fermenter for investigating its application in continuous ethanol production. The effects of cell concentration and transmembrane pressure difference on permeate flux were evaluated for testing the filtration module's performance. The internal cell retention system was operated in Saccharomyces cerevisiae continuous culture derived from sucrose, once fermentation conditions had been selected (30 °C, 1.25 -1.75 vvm, pH 4.5. Filter unit permeability was maintained by applying pulses of air. More than 97% of the grown cells were retained in the fermenter, reaching 51 g/L cell concentration and 8.51 g/L.h average ethanol productivity in culture with internal cell retention; this was twice that obtained in a conventional continuous culture. Key words: Membrane reactor, Saccharomyces cerevisiae, alcoholic fermentation, cell recycling.

Functional enhancement of chitosan and nanoparticles in cell culture, tissue engineering, and pharmaceutical applications

Directory of Open Access Journals (Sweden)

Wenjuan eGao

2012-08-01

Full Text Available Abstract: As a biomaterial, chitosan has been widely used in tissue engineering, wound healing, drug delivery, and other biomedical applications. It can be formulated in a variety of forms, such as powder, film, sphere, gel and fiber. These features make chitosan an almost ideal biomaterial in cell culture applications, and cell cultures arguably constitute the most practical way to evaluate biocompatibility and biotoxicity. The advantages of cell cultures are that they can be performed under totally controlled environments, allow high throughput functional screening, and are less costly, as compared to other assessment methods. Chitosan can also be modified into multilayer composite by combining with other polymers and moieties to alter the properties of chitosan for particular biomedical applications. This review briefly depicts and discusses applications of chitosan and nanoparticles in cell culture, in particular, the effects of chitosan and nanoparticles on cell adhesion, cell survival, and the underlying molecular mechanisms: both stimulatory and inhibitory influences are discussed. Our aim is to update the current status of how nanoparticles can be utilized to modify the properties of chitosan to advance the art of tissue engineering by using cell cultures.

Considering the culture of disability in cultural competence education.

Eddey, Gary E; Robey, Kenneth L

2005-07-01

Cultural competence extends beyond understanding those values, beliefs, and needs that are associated with patients' age or gender or with their racial, ethnic, or religious backgrounds. People hold many simultaneous cultural associations, and each have implications for the care process. The "culture of disability" is a pan-ethnic culture for which a set of physician competencies are required to ensure appropriate, culturally sensitive care to persons with congenital or acquired disabilities. Such competencies include communicating with patients who have deficits in verbal communication and avoidance of infantilizing speech; understanding the values and needs of persons with disabilities; the ability to encourage self-advocacy skills of patients and families; acknowledging the core values of disability culture including the emphasis on interdependence rather than independence; and feeling comfortable with patients with complex disabilities. Medical schools have developed programs to increase students' exposure to persons with disabilities and it is suggested that such programs are most effective when they are the result of collaboration with community-based facilities or organizations that serve persons with disabilities in the natural environment. Combining lecture-based instruction and structured experiences with the opportunity for students to interact with patients in their natural environments may facilitate development of competencies with respect to patients with disabilities. The culture of disability should be included as one of the many cultures addressed in cultural competence initiatives in medical school and residency curricula.

Developing a Plant Culture Medium Composed of Vinasse Originating from Haematococcus Pluvialis Culture

The mineral nutrients in vinasse provide support for algal and plant growth. Algal culture releases organic compounds into its liquid culture medium. These organic and inorganic substances can be useful for formulating a plant tissue culture medium, because tissue culture medium is composed of organic and inorganic components. Therefore, the aims of this study were to develop a plant culture medium by using the vinasse that is employed for Haematococcus pluvialis culture (algal filtrate); to investigate the possible beneficial effects of the biocompounds in the micropropagation of Nidularium procerum (Bromeliaceae), to evaluate quercetin content, total phenolics content in vinasse and to evaluate the cytotoxicity of the media by performing a bioassay with Artemia salina. The vinasse that originated from H. pluvialis culture can be used to formulate plant tissue culture at a 3% dilution, and its mineral nutrients can support In vitro plant growth, but some nutrients must be supplemented to enhance its efficiency. An efficient micropropagation protocol was developed for N. procerum. The micropropagated plants were suitable for transfer to the field (they were acclimatized). This culture medium provides a way to reuse wastewater, gives a rational alternative to vinasse disposal and adds value to what is currently considered to be an undesirable residue. Moreover, this process can reduce the production costs of clonal seedlings and/or bioactive compounds in biofactories. There was no apparent biostimulatory effect by the algal filtrate on morphogenesis; however, it did increase quercetin production. The H. pluvialis culture that was grown in the vinasse decreased the cytotoxicity and phenolic compound contents, which prevented explant tissue necrosis and represented a treatment for this residue for safer disposal in the environment.

The development of new photoresist materials for multi-lithography applications is crucial but a challenging task for semiconductor industries. During the last few decades, given the need for new resists to meet the requirements of semiconductor industries, several research groups have developed different resist materials for specific lithography applications. In this context, we have successfully synthesized a new molecular non-chemically amplified resist (n-CAR) (C3) based on the functionalization of aromatic hydroxyl core (4,4‧-(9H-fluorene-9,9-diyl)diphenol) with radiation sensitive sulfonium triflates for various lithography applications. While, micron scale features have been developed using i-line (365 nm) and DUVL (254 nm) exposure tools, electron beam studies on C3 thin films enabled us to pattern 20 nm line features with L/3S (line/space) characteristics on the silicon substrate. The sensitivity and contrast were calculated from the contrast curve analysis as 280 µC cm-2 and 0.025 respectively. Being an important parameter for any newly developed resists, the line edge roughness (LER) of 30 nm (L/5S) features were calculated, using SUMMIT metrology package, to be 3.66  ±  0.3 nm and found to be within the acceptable range. AFM analysis further confirmed 20 nm line width with smooth pattern wall. No deformation of patterned features was observed during AFM analysis which indicated good adhesion property between patterned resists and silicon substrates.

Since its appearance, as a result of the investigations of the accident in the Chernobyl Nuclear Power Plant, the term Safety Culture has been considered a key element to achieve a high level of safety in the nuclear installations, becoming a basic safety principle, internationally. The Cuban regulatory authority understood from very early the importance of the promotion and development of attitudes and characteristics in the organizations and personnel involved in the nuclear sector, reflecting a high Safety Culture, in order to propitiate a higher involvement of all employees in safety, contributing this way to the prevention of accidents in the nuclear facilities. Although the Cuban Nuclear Program was significantly reduced in the 90's, the regulatory authority has continued working in this direction and assimilated all the international experience for its application in its strategies for the development of a Safety Culture in the nuclear activities in the country. The present work summarizes the Cuban experience in the establishment of a National Program for the fostering and development of a Safety Culture. (author)

Changes in sensitivity to radiation and to bleomycin occurring during the life history of monolayer cultures of a mouse tumour cell line

The response to X-radiation and to bleomycin has been measured at a number of times during the life of monolayer cultures of EMT6 mouse tumour cells. Little change in radiation sensitivity was seen at any time and no loss of the shoulder to the survival curve occurred. Cultures in early plateau phase (where a considerable amount of cell proliferation is balanced by cell loss) showed a reduced sensitivity to bleomycin when compared with cells in exponential growth. However, after a longer period in plateau phase, when proliferation had virtually ceased, the sensitivity became greater than that of exponential phase cells. These findings are discussed with reference to the conflicting results of other workers. (author)

visible prescriptive formula for developing a strong safety culture. However, a prerequisite is genuine and consistent commitment by the top management of an organization to improving safety . Providing this commitment exists, the best recommendation is to due something tangible and visible to improve safety, preferably involving employees from the outset. The choice of practices for developing an improved safety culture should take account of the existing national and organizational culture in order to ensure effective implementation. The importance of the learning process has been emphasized. A mechanism is necessary to ensure that international experience of practices to develop a strong safety culture is shared on a regular and frequent basis. The maintenance and improvement of a safety culture is a process of continuous evolution. Indicators are available to assess positive progress in this evolution and to detect a weakening safety culture. (authors)

The effect of culture density and proliferation rate on the expression of ouabain-sensitive Na/K ATPase pumps in cultured human retinal pigment epithelium

International Nuclear Information System (INIS)

Burke, J.M.; Jaffe, G.J.; Brzeski, C.M.

1991-01-01

The number and activity of ouabain-sensitive Na/K ATPase pumps expressed by many cell types in vitro, including human retinal pigment epithelial cells (RPE), have been shown to decline with increasing culture density. Cell proliferation also declined as cultures became dense so it was unclear if pump number was modulated by cell proliferation or culture confluency. By exposing RPE cultures to various feeding regimens, using culture medium containing or lacking serum, it was possible to produce RPE cultures with a range of culture densities and growth rates. These were analyzed for proliferative activity by quantifying [ 3 H]thymidine incorporation and for Na/K ATPase pump number by measuring specific [ 3 H]ouabain binding. The results suggest that pump number is modulated by culture density and, further, that the density-dependent regulation of pump number requires serum. Although density-dependent modulation of culture growth is also serum requiring, cell proliferation and pump number did not appear to be related; cultures of similar density which differed significantly in growth rate had similar numbers of pumps. The view that elevated numbers of pumps were not necessarily found in proliferating cells was further supported by qualitative examination of radioautographs of cells dually labeled with [ 3 H]thymidine and [ 3 H]ouabain. Cycling cells which had [ 3 H]thymidine-labeled nuclei did not have notably higher labeling with [ 3 H]ouabain. However, [ 3 H]ouabain labeling, as an indicator of pump site number and distribution, did vary among cells in an RPE population and also within individual cells. This latter observation suggests that unpolarized RPE cells in sparse cultures may have regionally different requirements for ionic regulation

This study contributes to a differentiated understanding of maternal sensitivity in cultural and situational context. We investigated differences and similarities in German and Korean mothers' maternal sensitivity. We interviewed 92 German and 100 Korean mothers of first graders about their preference for proactive (anticipating children's needs) or reactive sensitivity (responding to children's direct cues) in different scenarios. Related parenting beliefs were assessed by asking the mothers to explain the reasons why they would prefer specific parenting behaviors. Results revealed significant cultural differences in reactive vs. proactive sensitivity preferences. Overall, German mothers were more likely to indicate that a mother should respond reactively and less likely to report that a mother should act proactively than were Korean mothers. Korean mothers gave preference to both reactive and proactive sensitivity depending on the scenario. With regard to parenting beliefs, analyses revealed that German and Korean mothers who preferred reactive sensitivity mainly explained their choices as attempts to encourage children's development of independence. In contrast, Korean and German mothers with a preference for proactive sensitivity were more likely to report that mothers would assist their children due to their immaturity in dealing with emotional distress. Results are discussed in the framework of the different meanings and functions of maternal sensitivity for socialization in different cultural contexts. PMID:23986740

Regional food culture and development.

Wahlqvist, Mark L; Lee, Meei-Shyuan

Food culture is most influenced by the locality of its origin, which will have been one of food acquisition and processing by various means. It is generally agreed, and is the basis of much United Nations, especially Food and Agriculture Organisation strategic development policy, that successful agriculture, horticulture and aquaculture along with fishing, underpin economically viable and healthy communities with their various food cultures. We also know that this must be in tandem with maternal literacy and operational health care systems. These elements are best represented on a regional basis. There is a growing consumer interest in knowing where one's food comes from as a measure of "food integrity". However, food production alone can be a precarious business and relate to a lesser or greater extent to local food culture and to trade, which may be complementary or at-odds with each other. Likewise, the local food culture may have its strengths and weaknesses as far as its ability to meet nutritional and health needs is concerned. Local food production may be restricted because of geographical or socio-economic conditions which preclude food diversity, although this may be compensated for by trade. Where food adequacy and diversity is compromised, and soils poor, various macronutrient, micronutrient (from animals and plants) and phytonutrient (nutritionally-advantageous food component from plants) deficiencies may be in evidence. These food system problems may be intertwined with food culture--for example, "rice-based and water-soluble vitamin poor"; "few animal-derived foods like meat, fish, eggs and milk with associated low calcium, vitamin D, Vitamin B12 and long chain n-3 fatty acid intakes"; "low fruit and vegetable intake with limited carotenoids and other phytonutrients".

Advances in technology have increased the likelihood that engineers will have to work in a global, culturally diverse setting. Many schools of engineering are currently revising their curricula to help students to develop cultural competence. However, our ability to measure cultural dispositions can be a challenge. The purpose of this project was to develop and test an instrument that measures the various aspects of cultural disposition. The results of the validation process verified that the hypothesised model adequately represented the data. The refined instrument produced a four-factor model for the overall construct. The validation process for the instrument verified the existence of specific subcomponents that form the overall cultural disposition construct. There also seems to be a hierarchical relationship within the subcomponents of cultural disposition. Additional research is needed to explore which aspects of cultural disposition affect an individual's ability to work effectively in a culturally diverse engineering team.

Progress of application, research and development, and design guidelines for shape memory alloy devices for cultural heritage structures in Italy

Castellano, Maria G.; Indirli, Maurizio; Martelli, Alessandro

2001-07-01

A wide ranging R&D Project (ISTECH) on validation and application of the Innovative Antiseismic Techniques (IATs) for the restoration of Cultural Heritage Structures (CUHESs), especially masonry buildings, based on the Shape Memory Alloys (SMAs), has been funded by the European Commission (EC), in the framework of the Environment and Climate RTD Programme. Because Traditional Restoration Techniques (TRTs) have sometimes proved inadequate in avoiding collapses and often too invasive, the use of superelastic SMA Devices (SMADs) has been developed. Theoretical and numerical studies, as well as intensive testing of material specimens, devices, structural models and in situ campaigns, show that SMADs can substantially increase the stability of masonry CUHESs exposed to an earthquake. Different SMAD types have been investigated to fulfil different structural needs and they can be custom designed taking into account each monument's characteristics. The successful results of the research and its exploitation led to important applications in Italy: the S. Giorgio Church Bell-Tower, located at Trignano, S. Martino in Rio, Reggio Emilia, damaged by the 15th October 1996 earthquake, the transept tympana of the S. Francesco Basilica in Assisi and the S. Feliciano Cathedral façade in Foligno, both heavily damaged by the September 1997 earthquake. In addition, further studies and applications of SMAD technology are foreseen in Italy in the next future, in the framework of Italian and European research projects and proposals.

Developing the security culture at the SEISMED Reference Centres.

Science.gov (United States)

Fowler, J

1996-01-01

The paper gives a brief summary of the SEISMED project and the particular role played by the Reference Centres. Details are given of the hardware and application systems in use in the Royal Hospitals (NHS) Trust (RHT), one of the SEISMED Reference Centres. It proposes, without verification, a definition of a Security Culture based on three criteria. These are suggested to be the "Awareness" the "Acceptance" and the "Actions" of the management and staff to improve Information Systems Security throughout the RHT. The way that "Awareness" was increased is shown by the specific initiatives commenced as a result of a CRAMM Risk Analysis and the management and staff training programmes. The specific initiatives mentioned include, an Information Systems Security Policy, a contingency and disaster recovery plan, improvements in the physical protection of equipment and changes to the method of access control. The "Acceptance" by the staff of these measures is considered and the success or failure of "Developing A Security Culture" examined. The role of SEISMED in this process is assessed.

Geopolymer Composites for Potential Applications in Cultural Heritage

Directory of Open Access Journals (Sweden)

Laura Ricciotti

2017-12-01

Full Text Available A new class of geopolymer composites, as materials alternative to traditional binders, was synthesized and its potentialities as restoration material in Cultural Heritage has been explored. This material has been prepared through a co-reticulation reaction in mild conditions of a metakaolin-based geopolymer inorganic matrix and a commercial epoxy resin. The freshly prepared slurry displays a consistency, workability and thixotropic behavior that make it suitable to be spread on different substrates in restoration, repair and reinforcement actions, even on walls and ceilings. Applicability and compatibility tests on tuff and concrete substrates were carried out and the microstructure of the samples in correspondence of the transition zone was analyzed by means of scanning electron microscope (SEM observations and energy dispersive spectroscopy (EDS mapping. Our studies pointed out the formation of a continuous phase between the geopolymer composite and tuff and concrete substrates, highlighting a high compatibility of the geopolymer binder with different kinds of materials. These features indicate a large potential for applications of these materials in Cultural Heritage.

In this paper we describe the current status of the CALDER project, which is developing ultra-sensitive light detectors based on superconductors for cryogenic applications. When we apply an AC current to a superconductor, the Cooper pairs oscillate and acquire kinetic inductance, that can be measured by inserting the superconductor in a LC circuit with high merit factor. Interactions in the superconductor can break the Cooper pairs, causing sizable variations in the kinetic inductance and, thus, in the response of the LC circuit. The continuous monitoring of the amplitude and frequency modulation allows to reconstruct the incident energy with excellent sensitivity. This concept is at the basis of Kinetic Inductance Detectors (KIDs) that are characterized by natural aptitude to multiplexed read-out (several sensors can be tuned to different resonant frequencies and coupled to the same line), resolution of few eV, stable behavior over a wide temperature range, and ease in fabrication. We present the results obtained by the CALDER collaboration with 2×2 cm{sup 2} substrates sampled by 1 or 4 Aluminum KIDs. We show that the performances of the first prototypes are already competitive with those of other commonly used light detectors, and we discuss the strategies for a further improvement.

Chen, J.-P.; Yang, T.-F.

2008-01-01

A thermo-sensitive chitosan-based copolymer hydrogel was used for harvesting living cell sheets. The hydrogel was tested for harvesting 3T3 cells after carrying out cell culture at 37 deg. C and incubating the confluent cells at 20 deg. C for spontaneous detachment of cell sheets from hydrogel surface without enzyme treatment. Results from cell viability assay and microscopy observations demonstrated that cells could attach to the hydrogel surface and maintain high viability and proliferation ability. Cell detachment efficiency from the hydrogel was about 80%. The detached cell sheet retained high viability and could proliferate again after transferred to a new culture surface

Full Text Available Women who inject drugs (WID are highly marginalized and stigmatized and experience ongoing discrimination in Georgia. Few opportunities exist for WID to receive publicly funded treatment for substance use disorders. The IMEDI (Investigating Methods for Enhancing Development in Individuals project was developed in response to the need for women-specific and women-centered treatment services. This paper described our approach to understanding the Georgian culture—and WID within that culture—so that we could integrate two interventions for substance use found effective in other Western and non-Western cultures and to outline how we refined and adapted our integrated intervention to yield a comprehensive women-centered intervention for substance use. Reinforcement Based Treatment (RBT and the Women’s CoOp (WC were adapted and refined based on in-depth interviews with WID (N=55 and providers of health services (N=34 to such women and focus groups [2 with WID (N=15 and 2 with health service providers (N=12]. The resulting comprehensive women-centered intervention, RBT+WC, was then pretested and further refined in a sample of 20 WID. Results indicated positive pre-post changes in urine screening results and perceived needs for both RBT+WC and a case management control condition. The approach to treatment adaptation and the revised elements of RBT+WC are presented and discussed.

Sensitivity and uncertainty analyses are important components of performance assessment activities for potential high-level radioactive waste repositories. The application of the adjoint sensitivity technique is demonstrated for the Leadville Limestone in the Paradox Basin, Utah. The adjoint technique is used sequentially to first assist in the calibration of the regional conceptual ground-water flow model to measured potentiometric data. Second, it is used to evaluate the sensitivities of the calculated pressures used to define local scale boundary conditions to regional parameters and boundary conditions

Application of perturbation theory to sensitivity calculations of PWR type reactor cores using the two-channel model

International Nuclear Information System (INIS)

Oliveira, A.C.J.G. de.

1988-12-01

Sensitivity calculations are very important in design and safety of nuclear reactor cores. Large codes with a great number of physical considerations have been used to perform sensitivity studies. However, these codes need long computation time involving high costs. The perturbation theory has constituted an efficient and economical method to perform sensitivity analysis. The present work is an application of the perturbation theory (matricial formalism) to a simplified model of DNB (Departure from Nucleate Boiling) analysis to perform sensitivity calculations in PWR cores. Expressions to calculate the sensitivity coefficients of enthalpy and coolant velocity with respect to coolant density and hot channel area were developed from the proposed model. The CASNUR.FOR code to evaluate these sensitivity coefficients was written in Fortran. The comparison between results obtained from the matricial formalism of perturbation theory with those obtained directly from the proposed model makes evident the efficiency and potentiality of this perturbation method for nuclear reactor cores sensitivity calculations (author). 23 refs, 4 figs, 7 tabs

Full Text Available Several ways have been done to encounter shrimp disease affecting cultured shrimp in Indonesian ponds in the last two decades. This research was aimed to find out the effect of different application of probiotic RICA4, RICA5, and RICA3 method on survival rate and production of white-leg shrimp (Litopenaeus vannamei cultured in ponds aerated with supercharge blower. RICA probiotics are bacteria probiotics produced by the Research and Development Institute for Coastal Aquaculture, originally isolated from seaweed and sea sediment. This experiment was carried out in completely randomized design using nine 250-m2 experimental ponds stocked with 15 shrimp fries/m2. There were three treatments namely: A=alternate use of three probiotics RICA4, RICA5, and RICA3; B=combination use of three probiotics RICA4, RICA5, and RICA3; and C=control (without probiotic, each treatment with three replications and cultured with supercharge blower. Variables observed in this study were survival rate and production of the shrimp calculated at the end of experiment, total vibrio count (TBV and total plate count of common bacteria (TPC of the pond waters and sediments monitored every two weeks. The results showed that application of probiotic RICA4, RICA5, and RICA3 applied either in alteration or in combination significantly increased survival rate (P0.05 of the white-leg shrimp. TBV/TPC ratio in the control pond waters after 10-weeks culture (over than 10% was relatively dangerous for the cultured white-leg shrimp. This shows that application of probiotic could prevent the growth of Vibrio spp in the cultured shrimp pond water.

Full Text Available The article acknowledges the situation of methodical crisis in modern research of social cognition related to the domination of reductive approaches that ignore the uniqueness of human psyche. Heuristicity of concepts of cultural-historical theory of psychological development of L.S. Vygotsky, which serves to overcome the apparent inconsistencies is substantiated. Models of social cognition based on the principles of cultural-historical psychology are described, those being the model of social cognition within phylogenesis of M. Tomasello, and the model of social cognition within ontogenesis of C. Fernyhough. Current situation in the area of mental health is reviewed from the standpoint of cultural-historical psychology, its specifics reflected in the increased burden on reflexive functions, that is, skills lying within the sphere of social cognition is substantiated. Modern psychotherapeutic apparatus directed to compensate social cognition deficits due to various psychiatric disorders is reviewed. The assumption that adolescense is sensitive period for the development of higher forms of social cognition is made, and a summary of researches supporting this assertion is presented. Main contradictions of modern-day maturing are enunciated. To conclude the presented theoretical analysis, a comprehensive multiple-factor model of social cognition is presented based on concepts of cultural-historical theory of L.S. Vygotsky.

Application of starter cultures to table olive fermentation: an overview on the experimental studies

Full Text Available Table olives are one of the oldest fermented foods and they are considered an important component of the Mediterranean diet, since their richness in monounsaturated fats (primarily oleic acid and phenolic compounds that may function as antioxidants in the human body; in the Western world they represent one of the most popular fermented vegetables but, despite its economic significance, table olive fermentation is still craft-based and empirical. In particular, such a type of fermentation results from the competitive activities among indigenous, contaminating microorganisms, the microbial balance depending on several intrinsic (pH, water activity, diffusion of nutrients from the drupe and level of anti-microbial compounds and extrinsic (temperature, oxygen availability and salt concentration factors. At present, to reduce the risk of spoilage and to achieve a more predictable process there is an increasing interest in developing starter cultures for table olives fermentation. Anyway, the application of starter cultures in the field of table olives is quite far from reaching the diffusion it has in other sectors of food industry (e.g., dairy products and alcoholic beverages. This review focuses on experimental researches devoted to studying starter cultures for possible application to table olive fermentation both at artisan and industrial level.

Full Text Available The article examines the applications aspects of cultural landscape for the preparation of the classical performing arts staging. Research findings highlighted that the cultural landscape (parks, estates, castles, bastions, etc. objects occupies an increasingly important role in public recreation and classical art development programs. At the same time it is noted that event’s aesthetic and emotional quality suffers due to the fact that no specific attention was given for the preparation of the event space. More methodological materials are necessary for preparation of this type of design spaces. In Lithuania classical performing arts events in cultural landscape open spaces are based on XVI–XVII century tradition and has good prospects for modern development. A review of some of the classical art events installations, based on the importance of quality of open spaces influence on the emotional impact, that should be an integral part of the cultural event. The author summarizes his experience of ballet events in open spaces in the cultural landscape – Klaipėda, Trakai. Presented is Tchaikovsky's ballet “Swan Lake” construction in Klaipėda John Hill project that includes infrastructure and environmental design concept: audience space, stage design, stage design performance solutions. Analogous key decisions are later adapted to the ballet performance in the natural environment of the lake Trakai. Experience of this project dictated the necessity of deeper understanding and methodological basis for the classical performing arts analysis and design.

Considerations on a concept of nuclear security culture and its development

International Nuclear Information System (INIS)

Miyamoto, Naoki

2013-01-01

In March 2012, domestic regulations regarding physical protection measures of nuclear facilities were amended to strengthen those measures. By these amendments, nuclear operators were requested to stipulate their corporate system to develop nuclear security culture on their physical protection plans, and therefore, attention has been drawn on a concept of nuclear security culture and its development. In the light of these situations, this presentation will consider the concept of nuclear security culture and its development. Firstly, focusing attention on 'culture', a concept of 'corporate culture' which is emphasized in corporate management will be analyzed. Then, with reference to 'safety culture', elements that seems to correspond to the concept of nuclear security culture will be extracted. Secondly, particularizing a 'corporate system to develop nuclear security culture', by reviewing a notion of 'Corporate Social Responsibility (CSR)' which attracts lots of attention recent years in terms of corporate sustainable development, results of examination regarding commitment structure of corporate chief executive and corporate risk management framework, which are considered to be efficient for the development of nuclear security culture, will be reported.

Developmental regulation of voltage-sensitive sodium channels in rat skeletal muscle

International Nuclear Information System (INIS)

Sherman, S.J.

1985-01-01

The developmental regulation of the voltage-sensitive Na + channel in rat skeletal muscle was studied in vivo and in vitro. In triceps surae muscle developing in vivo the development of TTX-sensitive Na + channel occurred primarily during the first three postnatal weeks as determined by the specific binding of [ 3 H]saxitoxin. This development proceeded in two separate phases. The first phase occurs independently of continuing motor neuron innervation and accounts for 60% of the adult density of TTX-sensitive Na + channels. The second phase, which begins about day 11, requires innervation. Muscle cells in primary culture were found to have both TTX-sensitive and insensitive Na + channels. The development of the TTX-sensitive channel, in vitro, paralleled the initial innervation-independent phase of development observed in vivo. The density of TTX-sensitive Na + channels in cultured muscle cells was regulated by electrical activity and cytosolic Ca ++ levels. Pharmacological blockade of the spontaneous electrical activity present in these cells lead to a nearly 2-fold increase in the surface density of TTX-sensitive channels. The turnover time of the TTX-sensitive Na + channel was measured by blocking the incorporation of newly synthesized channels with tunicamycin, an inhibitor of N-linked protein glycosylation. The regulation of channel density by electrical activity, cytosolic Ca ++ levels, and agents affecting cyclic neucleotide levels had no effect on the turnover time of the TTX-sensitive Na + channel, indicating that these regulatory agents instead affect the synthesis of the channel

Highlights: · Two highly sensitive immunoassays for determination of Cu(II) at sub ppb levels. · The heterologous competitive enzyme linked immunosorbent assay for heavy metals. · Haptenated protein directly conjugated with HRP can reduce the loss of HRP activity. - Abstract: Availability of highly sensitive assays for metal ions can help monitor and manage the environmental and food contamination. In the present study, a monoclonal antibody against Copper(II)-ethylenediaminetetraacetic acid was used to develop two sensitive ELISAs for Cu(II) analysis. Cobalt(II)-EDTA-BSA was the coating antigen in a heterologous indirect competitive ELISA (hicELISA), whereas Co(II)-EDTA-BSA-horseradish peroxidase (HRP) was the enzyme tracer in a heterologous direct competitive ELISA (hdcELISA). Both ELISAs were validated for detecting the content of Cu(II) in environmental waters. The ELISA data agreed well with those from graphite furnace atomic absorption spectroscopy. The methods of developing the Cu(II) hicELISA and hdcELISA are potentially applicable for developing ELISAs for other metals. The chelator-protein complexes such as EDTA-BSA and EDTA-BSA-HRP can form a suite of metal complexes having the consistent hapten density, location and orientation on the conjugates except the difference of the metal core, which can be used as ideal reagents to investigate the relationship between assay sensitivity and antibody affinities for the haptens and the analytes. The strategy of conjugating a haptenated protein directly with HRP can reduce the loss of HRP activity during the conjugation reaction and thus can be applicable for the development of ELISAs for small molecules.

Gibson, G.P.; Low, M.B.J.

1995-01-01

Nuclear Electric plc (NE) has always given the highest priority to safety. However, past emphasis has been directed towards ensuring safety thorough engineering design and hazard control procedures. Whilst the company did achieve high safety standards, particularly with respect to accidents, it was recognized that further improvements could be obtained. Analysis of the safety performance across a wide range of industries showed that the key to improving safety performance lay in developing a strong safety culture within the company. Over the last five years, NE has made great strides to improve its safety culture. This has resulted in a considerable improvement in its measured safety performance indicators, such as the number of incidents at international nuclear event scale (INES) rating 1, the number of lost time accidents and the collective radiation dose. However, despite this success, the company is committed to further improvement and a means by which this process becomes self-sustaining. In this way the company will achieve its prime goal, to ''ensure the safety of people, plant and the environment''. The paper provides an overview of the development of safety culture in NE since its formation in November 1989. It describes the research and international developments that have influenced the company's understanding of safety culture, the key initiatives that the company has undertaken to enhance its safety culture and the future initiatives being considered to ensure continual improvement.

Chudyk, C.; Müller, H.; Uhler, M.; Würriehausen, F.

2013-07-01

Since 2010, the state of Rhineland-Palatinate in Germany has developed a cultural landscape information system as a process to secure and further enrich aggregate data about its cultural assets. In an open dialogue between governing authorities and citizens, the intention of the project is an active cooperation of public and private actors. A cultural landscape information system called KuLIS was designed as a web platform, combining semantic wiki software with a geographic information system. Based on data sets from public administrations, the information about cultural assets can be extended and enhanced by interested participants. The developed infrastructure facilitates local information accumulation through a crowdsourcing approach. This capability offers new possibilities for e-governance and open data developments. The collaborative approach allows governing authorities to manage and supervise official data, while public participation enables affordable information acquisition. Gathered cultural heritage information can provide incentives for touristic valorisation of communities or concepts for strengthening regional identification. It can also influence political decisions in defining significant cultural regions worth of protecting from industrial influences. The presented cultural landscape information allows citizens to influence the statewide development of cultural landscapes in a democratic way.

Development and Characterization of Photoinduced Acrylamide-Grafted Polylactide Films for Biomedical Applications

Directory of Open Access Journals (Sweden)

Mijanur Rahman

2017-01-01

Full Text Available Surface grafting of biodegradable/biocompatible polylactide (PLA films by a UV-assisted reaction has been developed by employing a hydrophilic acrylamide (Am monomer, an N,N′-methylenebisacrylamide (MBAm cross-linker, and a camphorquinone (CQ/N,N′-dimethylaminoethylmethacrylate (DMAEMA photoinitiator/coinitiator system. The accomplishment of the process is confirmed by FTIR and XPS analyses. Physicochemical changes of the grafted PLA films are evaluated in terms of chemical structures, radiation-induced degradation followed by crystallization, morphology, thermal properties, and mechanical behavior. The results reveal that a low degree of PLA degradation through chain scission is observed in both blank and grafted PLA films. This generates more polar chain ends that can further induce crystallization. Results from contact angle measurements indicate that the grafted films have higher hydrophilicity and pH-responsive behavior. The incorporation of PAm on the film’s surface and the induced crystallization lead to improvements in certain aspects of mechanical properties of the films. The materials have high potential for use in biomedical and environmental applications, such as cell culture substrates or scaffolds or pH-sensitive absorbents.

Full Text Available ABSTRACT This study documented the number and results of mycobacterial culture and drug sensitivity testing (CDST in Mexico from 2009–2013 and assessed whether states with a higher risk of multidrug-resistant tuberculosis (MDR-TB performed more CDST and had more cultures showing MDR-TB. Data for this longitudinal, descriptive, operational research study came from the electronic records of 31 state public health laboratories in Mexico. The total number of CDSTs was 6 470, increasing from 2 143 in the first 2 years to 4 327 in the latter 3 years. There was a significant increase in the proportion of cultures showing sensitivity to all drugs, from 53.1% to 60.9% in 2011–2013 (P < 0.001 and a significant decrease in the proportion showing MDR-TB, from 28.2% in 2009 to 19.8% in 2013 (P < 0.001. Cases of extensively drug resistant tuberculosis were < 1% per year. In the 12 states with higher risk for MDR-TB, significantly more CDSTs (2 382 test were done in 2011–2013 than in the other 19 states (1 945 tests. Also, for each year the proportion of cultures showing MDR-TB was significantly higher in high risk MDR-TB states than in lower risk ones (P < 0.001. During the 5-year study period, CDST was scaled up in Mexico, particularly in high-risk MDR-TB states where a higher proportion of cultures showed MDR-TB. Scale up and wider coverage of CDST should continue.

The effect of culture density and proliferation rate on the expression of ouabain-sensitive Na/K ATPase pumps in cultured human retinal pigment epithelium

The number and activity of ouabain-sensitive Na/K ATPase pumps expressed by many cell types in vitro, including human retinal pigment epithelial cells (RPE), have been shown to decline with increasing culture density. Cell proliferation also declined as cultures became dense so it was unclear if pump number was modulated by cell proliferation or culture confluency. By exposing RPE cultures to various feeding regimens, using culture medium containing or lacking serum, it was possible to produce RPE cultures with a range of culture densities and growth rates. These were analyzed for proliferative activity by quantifying ({sup 3}H)thymidine incorporation and for Na/K ATPase pump number by measuring specific ({sup 3}H)ouabain binding. The results suggest that pump number is modulated by culture density and, further, that the density-dependent regulation of pump number requires serum. Although density-dependent modulation of culture growth is also serum requiring, cell proliferation and pump number did not appear to be related; cultures of similar density which differed significantly in growth rate had similar numbers of pumps. The view that elevated numbers of pumps were not necessarily found in proliferating cells was further supported by qualitative examination of radioautographs of cells dually labeled with ({sup 3}H)thymidine and ({sup 3}H)ouabain. Cycling cells which had ({sup 3}H)thymidine-labeled nuclei did not have notably higher labeling with ({sup 3}H)ouabain. However, ({sup 3}H)ouabain labeling, as an indicator of pump site number and distribution, did vary among cells in an RPE population and also within individual cells. This latter observation suggests that unpolarized RPE cells in sparse cultures may have regionally different requirements for ionic regulation.

Marine shrimp culture in Thailand has been developed continuously for the past two decades. This development will ensure the highest level of shrimp quality that will be suitable for the consumption of the people in the country and also aboard. The trend of culture system emphasizes on disease prevention more than treatment which will consequently limit the application of drug and chemicals. Application of pro biotic has been one means of this prevention that are commonly practiced by shrimp farmers. This research was conducted to compare the efficacy of normal Bacillus subtilis isolate from shrimp intestine and an irradiated B. subtilis as a pro biotic in shrimp feed. It was found that overall results were quite the same. These included the broth Co-culture assay. Effects on immune functions were conducted with Penaeus monodon with initial average weight of 17 gms by feeding with 3 gms/kg feed of spore of these two pro biotic for two mouths. The results indicated that both pro biotic caused significant improvement on percent phagocytosis only at the forth week of feeding trial and the overall enhancement of bactericidal activity. However, total haemocyte count and phenoloxidase activity were not altered. Total bacterial count in shrimp intestine was also conducted during the two month trial. the results indicated significant reduction of Vibrio spp. of both pro biotic groups when compared with the control. Number of Bacillus spp. in intestine were continuously high even after pro biotic treatment had been stopped Growth rate of experiment and control shrimp was not significantly different.

2008-09-01

Full Text Available Abstract Background Vibrio parahaemolyticus is a marine seafood-borne pathogen causing gastrointestinal disorders in humans. Thermostable direct hemolysin (TDH and TDH-related hemolysin (TRH are known as major virulence determinants of V. parahaemolyticus. Most V. parahaemolyticus isolates from the environment do not produce TDH or TRH. Total V. parahaemolyticus has been used as an indicator for control of seafood contamination toward prevention of infection. Detection of total V. parahaemolyticus using conventional culture- and biochemical-based assays is time-consuming and laborious, requiring more than three days. Thus, we developed a novel and highly specific loop-mediated isothermal amplification (LAMP assay for the sensitive and rapid detection of Vibrio parahaemolyticus. Results The assay provided markedly more sensitive and rapid detection of V. parahaemolyticus strains than conventional biochemical and PCR assays. The assay correctly identified 143 V. parahaemolyticus strains, but did not detect 33 non-parahaemolyticus Vibrio and 56 non-Vibrio strains. Sensitivity of the LAMP assay for direct detection of V. parahaemolyticus in pure cultures and in spiked shrimp samples was 5.3 × 102 CFU per ml/g (2.0 CFU per reaction. The sensitivity of the LAMP assay was 10-fold more sensitive than that of the conventional PCR assay. The LAMP assay was markedly faster, requiring for amplification 13–22 min in a single colony on TCBS agar from each of 143 V. parahaemolyticus strains and less than 35 min in spiked shrimp samples. The LAMP assay for detection of V. parahaemolyticus required less than 40 min in a single colony on thiosulfate citrate bile salt sucrose (TCBS agar and 60 min in spiked shrimp samples from the beginning of DNA extraction to final determination. Conclusion The LAMP assay is a sensitive, rapid and simple tool for the detection of V. parahaemolyticus and will facilitate the surveillance for control of contamination of V

Full Text Available This study aims to identify and analyze the cultural conflicts between the main characters in the novel Not Without my Daughter (NW. The analysis was carried out through the following process. The first procedure related to problems of classification i.e. cross cultural conflicts. The next phase of data analysis related to the colletion data of cross cultural conflicts in NW. The last phase is presentation the result of the analysis that had been conducted in this research. Having analyzed the data, the researcher concludes  that cultural conflicts occured in NW because of  stereotype, prejudice, and ethnocentrism. Cultural conflicts can be prevented if we increase our awareness of our own attitudes and learn to be sensitive to cross-cultural differences. However, if we develop intercultural sensitivity, it does not mean that we need to lose our cultural identities-but rather that we recognize cultural influences within ourselves and within others.

Applications of pressure-sensitive dielectric elastomer sensors

Böse, Holger; Ocak, Deniz; Ehrlich, Johannes

2016-04-01

Dielectric elastomer sensors for the measurement of compression loads with high sensitivity are described. The basic design of the sensors exhibits two profiled surfaces between which an elastomer film is confined. All components of the sensor were prepared with silicone whose stiffness can be varied in a wide range. Depending on details of the sensor design, various effects contribute to the enhancement of the capacitance. The intermediate elastomer film is stretched upon compression and electrode layers on the elastomer profiles and in the elastomer film approach each other. Different designs of the pressure sensor give rise to very different sensor characteristics in terms of the dependence of electric capacitance on compression force. Due to their inherent flexibility, the pressure sensors can be used on compliant substrates such as seats or beds or on the human body. This gives rise to numerous possible applications. The contribution describes also some examples of possible sensor applications. A glove was equipped with various sensors positioned at the finger tips. When grabbing an object with the glove, the sensors can detect the gripping forces of the individual fingers with high sensitivity. In a demonstrator of the glove equipped with seven sensors, the capacitances representing the gripping forces are recorded on a display. In another application example, a lower limb prosthesis was equipped with a pressure sensor to detect the load on the remaining part of the leg and the load is displayed in terms of the measured capacitance. The benefit of such sensors is to detect an eventual overload in order to prevent possible pressure sores. A third example introduces a seat load sensor system based on four extended pressure sensor mats. The sensor system detects the load distribution of a person on the seat. The examples emphasize the high performance of the new pressure sensor technology.

Culture Sustainability: Culture Quotient (CQ and Its Quantitative Empirical Application to Chinese Cities

Jing Lin

2016-11-01

Full Text Available Culture sustainability is one of the indispensable components of sustainability. Culture has likely always been an important element for promoting urban and rural sustainable development. It is now playing an increasingly significant role in sparking and incubating innovation, which is becoming the main driver of economic growth and competitiveness. Unfortunately, little research has been conducted on how much culture matters to economic performance in a quantitative way. Therefore, in this paper, which is based on an intensive literature review, we try to specifically quantify the importance of culture to urban development in general and urban economic performance in particular, by proposing an index system dubbed as the Culture Quotient (CQ. Following this, an integrated database of 297 prefectural-level cities in China is accordingly established. By manipulating the database, the CQ value for each city is then calculated by using principal component analysis with SPSS (19.0. Afterwards, spatial pattern by CQ value tier is presented and illustrates urban China’s “winner-take-all” phenomenon, with the predominance by the three giant urban clusters in the coastal area, i.e., the Jing (Beijing-Jin (Tianjin-Ji (Hebei province-based Bohai rim region, Yangtze River delta, Pearl River delta, as well as some mega-cities such as Chengdu and Wuhan in other parts of China. More precisely, the regression analysis shows that there is a strong positive relationship between CQ and gross domestic product (GDP, with the striking result that every increase of one percentage point in CQ will induce a five percentage point increment in GDP. Although the finding makes an impressive and convincing case that culture does exert a great impact on urban economic development, and can also be measured in a quantitative way in Chinese cases, more cases from other countries need to be included for further verification and confirmation. We therefore urgently call for

Full Text Available As society grows increasingly diverse, it is critical that youth development professionals are equipped with cultural core competencies. This descriptive study gauged the perceived level of cultural competence among 4-H Youth Development professionals from a Southern state in the United States. Based on the 4-H Professional Research, Knowledge, and Competency (PRKC Model (Stone & Rennekamp, 2004, youth development professionals rated their cultural competence (equity, access, and opportunity in eight core competency areas. Based on a five-point Likert scale ranging from 0 = No knowledge to 4 = Expert, youth development professionals evaluated their cultural competence ranging from 0.66 to 4.00. According to an interpretive scale, most youth development professionals rated their competence as intermediate. Participants reported the skills of active listening and an open attitude as areas in which they felt most competent. Areas of least competence were community outreach policies and procedures. No significant relationships existed between the demographic variables of gender, degree earned, and field of study when compared to perceived cultural competence. The findings will be used to detect deficiencies and create opportunities for professional training and development experiences in supporting the cultural competence and growth of youth professionals.

An anti-capitalist cultural bias, through directed within-family human capital transmission, adversely affects the supply of entrepreneurial talent and risk-taking. This limits economic progress if aggregate productivity is low. When productivity is high, economic incentives can overcome cultural inertia. Though the income level depends on culture, the growth rate in this case does not.

Full Text Available In this paper the relevance of understanding the different meanings of culture in the counseling profession is presented. Two approaches to the concept of culture as they relate to counseling are suggested: the first approach stresses the organisational culture of the institution where the counselor works; the second —the multicultural approach— calls for the complex recognition of the variety of ethnic cultural backgrounds of those involved in the counseling situation. Professional practices are analysed as means for the reinforcement of present conditions or as ways for changing them. The concepts of empowerment of and advocacy for our clients are put forward as main components in the challenging new roles of the counseling profession. Implications for counselors are suggested.

A highly sensitive and specific assay for vertebrate collagenase has been developed using a [ 14 C]-labeled collagen substrate and a combination of SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) and fluorography to identify and quantitate the digestion products. The assay was sufficiently sensitive to permit the detection and quantitation of collagenase activity in 0.1 μl of gingival sulcal fluid, and in samples of cell culture medium without prior concentration. The assay has also been used to detect the presence of inhibitors of collagenolytic enzymes in various cell culture fluids. (author)

Full Text Available The present work deals with the separation and some characteristics of ATPase activities bound with plant membanes prepared from sterile cultures of Spirodela polyrrhiza. The membrane-bound ATPases were separated on sucrose gradients and distinguished by membrane density and sensitivity to several inhibitors. The results showed that N0-3-sensitive ATPase activity associated with the tonoplast was localized at a sucrose density between 1.095-1.117 g•cm-3. The vanadate-sensitive ATPase activity bound with the plasma membrane showed a density between 1.127-1.151 g•cm-3. Both ATPases were insensitive to azide and oligomycin and were separable from markers for mitochondria.

Full Text Available The subject of this article is the development of the cultural construction and the emergence of the Constitutional Revolution in Iran. This study, by examining the cultural structure of the Qajar era of the Naser-al-Din Shah period wants to investigate the cause of the Constitutional Revolution. The findings of this research, which have been collected by historical-analytical method, indicate that the pattern of development in the Qajar era is consistent with the pattern of unbalanced development. In this sense, by starting educational, political and military reforms in the Qajar era specially Nasser-al-Din Shah, gradually the cultural structure apart from the traditional political structure. This development provided the basis for the emergence of new intellectuals and elites with new political ideas in the field of governance methods. However, the attenuation of political structure and the backwardness of political development from cultural development faced with some obstacles. Political system instead of creating a development along with gradual cultural development and consolidating its position through the persuasion of the community, in fact to maintain integrity in the social system was resorted to force and preferred force and compulsion to persuasion. The kind of reaction and opposition of the political power structure against the modern intellectual movement, which contained new political demands in the area of governance and freedom, led to the weakness and, finally, the collapse of the Qajar political system and the constitutional revolution.

2017-01-01

The Montreal Cognitive Assessment (MoCA) is widely used to screen for mild cognitive impairment (MCI). While there are many available versions, the cross-cultural validity of the assessment has not been explored sufficiently. We aimed to interrogate the validity of the MoCA in a cross-cultural context: in differentiating MCI from normal controls (NC); and identifying cut-offs and adjustments for age and education where possible. This review sourced a wide range of studies including case-control studies. In addition, we report findings for differentiating dementias from NC and MCI from dementias, however, these were not considered to be an appropriate use of the MoCA. The subject of the review assumes heterogeneity and therefore meta-analyses was not conducted. Quality ratings, forest plots of validated studies (sensitivity and specificity) with covariates (suggested cut-offs, age, education and country), and summary receiver operating characteristic curve are presented. The results showed a wide range in suggested cutoffs for MCI cross-culturally, with variability in levels of sensitivity and specificity ranging from low to high. Poor methodological rigor appears to have affected reported accuracy and validity of the MoCA. The review highlights the necessity for cross-cultural considerations when using the MoCA, and recognizing it as a screen and not a diagnostic tool. Appropriate cutoffs and point adjustments for education are suggested.

Kamaka, Martina L

2010-06-01

The design of a cultural competency curriculum can be challenging. The 2002 Institute of Medicine report, Unequal Treatment, challenged medical schools to integrate cross-cultural education into the training of all current and future health professionals. However, there is no current consensus on how to do this. The Department of Native Hawaiian Health at the John A. Burns School of Medicine formed a Cultural Competency Curriculum Development team that was charged with developing a curriculum for the medical school to address Native Hawaiian health disparities. By addressing cultural competency training of physicians, the team is hoping to help decrease the health disparities found in Native Hawaiians. Prior attempts to address culture at the time consisted of conferences sponsored by the Native Hawaiian Center of Excellence for faculty and clinicians and Problem Based Learning cases that have imbedded cultural issues. Gather ideas from focus groups of Native Hawaiian stake- holders. The stakeholders consisted of Native Hawaiian medical students, patients and physicians. Information from the focus groups would be incorporated into a medical school curriculum addressing Native Hawaiian health and cultural competency training. Focus groups were held with Native Hawaiian medical students, patients and physicians in the summer and fall of 2006. Institutional Review Board approval was obtained from the University of Hawaii as well as the Native Hawaiian Health Care Systems. Qualitative analysis of tape recorded data was performed by looking for recurrent themes. Primary themes and secondary themes were ascertained based on the number of participants mentioning the topic. Amongst all three groups, cultural sensitivity training was either a primary theme or secondary theme. Primary themes were mentioned by all students, by 80% of the physicians and were mentioned in all 4 patient groups. Secondary themes were mentioned by 75% of students, 50% of the physicians and by 75

Growth of human T lymphocyte colonies from whole blood: culture requirements and applications

Knox, S.J.; Wilson, F.D.; Greenberg, B.R.; Shifrine, M.

1982-01-01

Growth of human lymphocyte colonies from whole blood following stimulation with PHA, Con A, or PPD is described. Individual colony cells were identified as T lymphocytes on the basis of surface marker and enzyme cytochemical characterizations. Colony formation increased as a power function over a wide range of cell concentrations above a critical minimal concentration. The whole blood culture system eliminates possible selective effects of lymphocyte colony techniques utilizing gradient-enriched lymphocyte fractions and more closely approximates the in vivo milieu. The whole blood colony method is more sensitive for the detection of low-level radiation effects on lymphocytes than widely used tests that measure 3 H-thymidine incorporation. In preliminary studies, researchers used the whole blood method to determine the relative radiosensitivity of lymphocytes from humans with various hematopoietic disorders, and observed abnormalities in mitogen responsiveness and colony formation in some of the patient groups. This method has wide application for studies in cellular and clinical immunology

Oblow, E.M.; Perey, F.G.

1984-01-01

A comprehensive rigorous theory is developed for screening sensitivity coefficients in largescale modeling applications. The theory uses Bayesian inference and group theory to establish a probabilistic framework for solving an underdetermined system of linear equations. The underdetermined problem is directly related to statistical screening sensitivity theory as developed in recent years. Several examples of the new approach to screening are worked out in detail and comparisons are made with statistical approaches to the problem. The drawbacks of these latter methods are discussed at some length

This study investigated the number of blood culture-positive cattle among 215 animals clinically suspected of having bacterial endocarditis. For animals that were necropsied, the sensitivity, specificity and predictive value of the diagnosis of endocarditis were calculated on the basis...... of the isolation of the causative bacteria from blood. Furthermore, it was investigated whether the glutaraldehyde coagulation time, total leucocyte count, per cent neutrophil granulocytes, pulse rate and duration of disease could help to discriminate endocarditis from other diseases. Among 138 animals necropsied...... the sensitivity, specificity and predictive value of blood cultivation were 70.7 per cent, 93.8 per cent and 89.1 per cent, respectively. None of the other measurements could be used to discriminate between endocarditis and non-endocarditis cases....

Identification of new drugs and predicting drug response are major challenges in oncology, especially for brain tumors, because total surgical resection is difficult and radiation therapy or chemotherapy is often ineffective. With the aim of developing a culture system close to in vivo conditions for testing new drugs, we characterized an ex vivo three-dimensional culture system based on a hyaluronic acid-rich hydrogel and compared it with classical two-dimensional culture conditions. U87-MG glioblastoma cells and seven primary cell cultures of human glioblastomas were subjected to radiation therapy and chemotherapy drugs. It appears that 3D hydrogel preserves the original cancer growth behavior and enables assessment of the sensitivity of malignant gliomas to radiation and drugs with regard to inter-tumoral heterogeneity of therapeutic response. It could be used for preclinical assessment of new therapies. - Highlights: • We have compared primary glioblastoma cell culture in a 2D versus 3D-matrix system. • In 3D morphology, organization and markers better recapitulate the original tumor. • 3D-matrix culture might represent a relevant system for more accurate drug screening.

The effects of caffeine (CF), γ-irradiation + CF post-treatment on chromosomal aberrations were studied in lymphocyte cultures from a patient with ataxia telangiectasia (AT), his parents and brother. In the studied family both the homozygotes and the obligatory heterozygotes of AT showed increased sensitivity to CF post-treatment. Individual differences in sensitivity to γ-irradiation + CF post-treatment proved to be correlated with the sensitivity of non-irradiated cells to CF treatment, but not to γ-irradiation.

Full Text Available Purpose : to substantiate the phenomenon of formation of physical culture of the individual in terms of theoretical and methodological approaches to the development of socio-cultural competence of future teachers. Material : 22 literary sources analyzed on the issue of formation of physical culture of the individual. Used cultural studies, axiological and competence approach. Results : define the concept of socio-cultural competence of the teacher of physical education. Competence is considered as an integrative motivational tumor - activity sphere of the individual. It determines the focus of an expert on the formation of spiritual values and is the foundation for its further self-development. Disclosed structure sociocultural competence of the teacher in the unity components: cognitive, motivational-value, behavioral. For each component defined system of spiritual values. The system covers the socio- psychological, mental and cultural values of physical culture. Conclusions : the sociocultural competence of the teacher of physical education meaningful and functionally related to the values of the physical culture of the individual. Spiritual, value the personality of the teacher - is the foundation for all of the components of socio-cultural competence. This competence provides social and cultural development of the individual.
