    Full Text Available Introduction: Patient education is influenced by cultural factors. This study aims to find out the role of culture in patient education. Methods: A qualitative study was conducted on 23 Iranian nurses. Inclusion criteria were minimum 5 years of working experience in clinical nursing. Semistructured face to face interviews were used to collect the data. Interviews were taped, transcribed and analyzed using content analysis method. Results: The main theme of ‘cultural sensitivity’ was extracted from the interviews. Sub-themes were cultural divergence, cultural connection literacybased instruction. Conclusion: A dynamic process of patient education is influenced by various cultural factors. Nurses must be aware of the cultural norms in patient education to meet their expectations in a respectful manner.

    The primary culture of insect cells often suffers from problems with poor reproducibility in the quality of the final cell preparations. The cellular composition of the explants (cell number and cell types), surgical methods (surgical duration and surgical isolation), and physiological and genetic differences between donors may be critical factors affecting the reproducibility of culture. However, little is known about where biological variation (interindividual differences between donors) ends and technical variation (variance in replication of culture conditions) begins. In this study, we cultured larval fat bodies from the Japanese rhinoceros beetle, Allomyrina dichotoma, and evaluated, using linear mixed models, the effect of interindividual variation between donors on the reproducibility of the culture. We also performed transcriptome analysis of the hemocyte-like cells mainly seen in the cultures using RNA sequencing and ultrastructural analyses of hemocytes using a transmission electron microscope, revealing that the cultured cells have many characteristics of insect hemocytes.

    The United Nations Educational, Scientific, and Cultural Organization (UNESCO) is undertaking a project that will produce a state-of-the-art paper on sociocultural factors affecting demographic behavior. Particular emphasis will be placed on reproductive behavior in Africa, Asia, Latin America, and the Arab states region. The extent to which this information is incorporated in current population policies and programs will also be examined, and recommendations will be made. The factors to be studied include family and kinship structure; gender status and role; patterns of sexual relations and procreation in general and adolescent sexual behavior and fertility; religion, beliefs, customs, and traditions concerned with sexual relations and procreation; child rearing, socialization, and education; status and role of women; and sociocultural change, change agents, and influentials. The literature search will provide an inventory of methodologies. Guidelines on the use of the methodologies will be drafted for use by project personnel. These will later be tested in pilot studies in rural and urban communities in selected developing countries. The goal is to design programs that will accelerate contraceptive acceptance and sustain contraceptive practice by being sensitive to the sociocultural influences on the reproductive behavior of different subpopulations.

  4. Some cultural factors affecting costs of fertility regulation.

    1984-01-01

    This paper presents a framework of the costs or constraints in the use of fertility regulation, reviews the existing knowledge on the subject in a cross-cultural context, and indicates the need for further studies. It is suggested that the apparent contradiction noted in fertility surveys between a couple's desire to have no more children or to postpone the next birth and actual behavior can be explained by the costs involved in the use of fertility regulation methods. The costs of fertility regulation can be broadly classified into 4 categories: 1) physical/health (disruption of menstrual cycle, side effects and health hazards of contraceptive methods, perceived health hazards based on ethno-physical concepts, and sacrifice of sexual pleasure); 2) psychic (violation of sexual modesty and human dignity, conflict with religious beliefs; 3) social opinion (challenges to spouse and sex role expectations, challenges to social influence group); and 4) economic (money, time). The economic costs of fertility regulation to individuals vary greatly according to the presence or absence of public sector family planning programs. A substantial part of these costs could be eliminated by national and international programs. So far, no study has focused on the costs of fertility regulation and factors affecting them. A methodology that combines elements of both a questionnaire survey and anthropological investigation and collects data on both the individual and community levels may be most amenable to assessing the impact of costs on the use or nonuse of fertility regulation.

    2015-01-01

    The intention of this present paper is to explore the relationship between culture and perception and the cultural fac⁃tors that affect people’s perceptions from different cultural backgrounds. This study is based on a case, which is a news report about the cultural conflict between an old Chinese father and her daughter who has been living in Canada for eight years. De⁃tailed information has been acquired by the author using relative books, journals as well as her own understanding and interpreta⁃tion. It is concluded that to be aware of the cultural factors is of great importance to understand why people from different cul⁃tures have quite different perceptions toward the same thing, which can help to reduce the conflicts and misunderstandings in in⁃tercultural communication.

  7. Socio-cultural and economic factors affecting food consumption patterns in the Arab countries.

    Several factors have been found to determine the dietary habits of the people in the Arab world. Food consumption pattern has dramatically changed in some Arab countries as a result of sudden increase in income from oil revenue. It is believed that food subsidy policy has adversely affected the food habits in the Gulf states by encouraging the intake of fat, sugar, rice, wheat flour and meat. Socio-cultural factors such as religion, beliefs, food preferences, gender discrimination, education and women's employment all have a noticeable influence on food consumption patterns in this region. Mass media, especially televised food advertisements, play an important role in modifying the dietary habits. The migration movement, particularly that which was carried out during the 70s has a great impact on the food practices in many Arab countries. Comprehensive studies on social, cultural and economic factors associated with food consumption patterns in the Arab region are highly recommended.

  8. Assessment of cultivation factors that affect biomass and geraniol production in transgenic tobacco cell suspension cultures.

    Nikolay Vasilev

    Full Text Available A large-scale statistical experimental design was used to determine essential cultivation parameters that affect biomass accumulation and geraniol production in transgenic tobacco (Nicotiana tabacum cv. Samsun NN cell suspension cultures. The carbohydrate source played a major role in determining the geraniol yield and factors such as filling volume, inoculum size and light were less important. Sucrose, filling volume and inoculum size had a positive effect on geraniol yield by boosting growth of plant cell cultures whereas illumination of the cultures stimulated the geraniol biosynthesis. We also found that the carbohydrates sucrose and mannitol showed polarizing effects on biomass and geraniol accumulation. Factors such as shaking frequency, the presence of conditioned medium and solubilizers had minor influence on both plant cell growth and geraniol content. When cells were cultivated under the screened conditions for all the investigated factors, the cultures produced ∼ 5.2 mg/l geraniol after 12 days of cultivation in shaking flasks which is comparable to the yield obtained in microbial expression systems. Our data suggest that industrial experimental designs based on orthogonal arrays are suitable for the selection of initial cultivation parameters prior to the essential medium optimization steps. Such designs are particularly beneficial in the early optimization steps when many factors must be screened, increasing the statistical power of the experiments without increasing the demand on time and resources.

    To evaluate the variable factors affecting the results of percutaneous needle biopsies for infectious spondylitis. In all, 249 patients who underwent both MRI and percutaneous needle biopsies due to a suspicion of infectious spondylitis were evaluated with respect to the following factors: the usage of antibiotics before the procedure, the location of the biopsy, the guiding equipment used, the experience level of the operators, and the number of biopsies performed. The positivity of culture in cases of treated with antibiotics (16.3%) before the biopsy was lower than in the untreated cases (30.5%) (p = 0.004). Biopsies performed at the abscess (43.5%) and with fluoroscopic guidance (27.8%) showed higher culture positivity as well. The experience level of the operators and the number of biopsies had no effect on culture positivity. The usage of antibiotics before the biopsy, the biopsy's location, and the guiding equipment used affect the culture positivity, while the experience levels of the operators and the number of biopsies do not have an effect.

    2009-01-01

    A study was conducted to improve 9-methoxycanthin-6-one productivity (potential anti-tumour compound) from callus cultures of Eurycoma longifolia (Tongkat Ali). Several factors affecting 9-methoxycanthin-6-one production in callus cultures such as different medium compositions and physical factors were investigated and analyzed. Results show that a higher production of 9-methoxycanthin-6-one (3.84 mg(g-1 DW (Dry Weight)) is obtained from callus cultured in 1/4 MS basal media. At fructose of 2% (w/v), the production of 9-methoxycanthin-6-one (4.59 mg(g-1 DW) is promoted to gain the highest yield, compared to other carbon sources tested. The addition of 2.0-mg(L-1 dicamba also increases 9-methoxycanthin-6-one production (12.3 mg(g-1 DW). Higher production of 9-methoxycanthin-6-one was obtained at pH 5.5 (1.53 mg(g-1 DW). Production of 9-methoxycanthin-6-one (2.34 mg(g-1 DW) in callus cultures is also increased when the medium is added with 1(10-1 μM phenylalanine. This study suggests that the successful production of 9-methoxycanthin-6-one in vitro cultures has a potential in large-scale production using bioreactor technology.

    2016-01-01

    Background The high rate of maternal mortality reported in The Gambia is influenced by many factors, such as difficulties in accessing quality healthcare and facilities. In addition, socio-cultural practices in rural areas may limit the resources available to pregnant women, resulting in adverse health consequences. The aim of this study is to depict the gender dynamics in a rural Gambian context by exploring the social and cultural factors affecting maternal health. Methods and Findings Five focus group discussions that included 50 participants (aged 15–30 years, with at least one child) and six in-depth interviews with traditional birth attendants were conducted to explore perceptions of maternal health issues among rural women. The discussion was facilitated by guides focusing on issues such as how the women perceived their own physical health during pregnancy, difficulties in keeping themselves healthy, and health-related problems during pregnancy and delivery. The data resulting from the discussion was transcribed verbatim and investigated using a qualitative thematic analysis. In general, rural Gambian women did not enjoy privileges in their households when they were pregnant. The duties expected of them required pregnant women to endure heavy workloads, with limited opportunities for sick leave and almost nonexistent resources to access prenatal care. The division of labor between men and women in the household was such that women often engaged in non-remunerable field work with few economic resources, and their household duties during pregnancy were not alleviated by either their husbands or the other members of polygamous households. At the time of delivery, the decision to receive care by trained personnel was often beyond the women’s control, resulting in birth-related complications. Conclusions Our findings suggest that despite women’s multiple roles in the household, their positions are quite unfavorable. The high maternal morbidity and mortality

    The goal of this paper is to link a bridge between social relationship and cultural variation to predict conversants' non-verbal behaviors. This idea serves as a basis of establishing a parameter based socio-cultural model, which determines non-verbal expressive parameters that specify the shapes of agent's nonverbal behaviors in HAI. As the first step, a comparative corpus analysis is done for two cultures in two specific social relationships. Next, by integrating the cultural and social parameters factors with the empirical data from corpus analysis, we establish a model that predicts posture. The predictions from our model successfully demonstrate that both cultural background and social relationship moderate communicative non-verbal behaviors.

    Communication with children who have life-threatening illnesses is a major challenge. Communication practices are greatly influenced by factors such as the child's age, the parents' wishes, and the cultural norms. This article presents the case of a 12-year-old Japanese boy with advanced hepatoblastoma. The patient also was diagnosed with Asperger's syndrome, which impairs interpersonal communication. The case is discussed from the perspective of clinical ethics, especially with regard to truth telling. The health care team faced an ethical dilemma because of the complications involved. Physicians treating children with cancer should be aware of these issues to be able to effectively communicate with their patients.

    Full Text Available Abstract Background Traditionally Nepalese society favors high fertility. Children are a symbol of well-being both socially and economically. Although fertility has been decreasing in Nepal since 1981, it is still high compared to many other developing countries. This paper is an attempt to examine the demographic, socio-economic, and cultural factors for fertility differentials in Nepal. Methods This paper has used data from the Nepal Demographic and Health Survey (NDHS 2006. The analysis is confined to ever married women of reproductive age (8,644. Both bivariate and multivariate analyses have been performed to describe the fertility differentials. The bivariate analysis (one-way ANOVA was applied to examine the association between children ever born and women's demographic, socio-economic, and cultural characteristics. Besides bivariate analysis, the net effect of each independent variable on the dependent variable after controlling for the effect of other predictors has also been measured through multivariate analysis (multiple linear regressions. Results The mean numbers of children ever born (CEB among married Nepali women of reproductive age and among women aged 40-49 were three and five children, respectively. There are considerable differentials in the average number of children ever born according to women's demographic, socio-economic, and cultural settings. Regression analysis revealed that age at first marriage, perceived ideal number of children, place of residence, literacy status, religion, mass media exposure, use of family planning methods, household headship, and experience of child death were the most important variables that explained the variance in fertility. Women who considered a higher number of children as ideal (β = 0.03; p Conclusion The average number of children ever born is high among women in Nepal. There are many contributing factors for the high fertility, among which are age at first marriage, perceived ideal

    Full Text Available Effects of media compositions on biomass and lipid accumulation of the isolate Chlorella sp. TISTR 8990 were investigated under a Plackett-Burman experimental design with mixotrophic cultivation conditions. Under this experimental design there were 15 different runs with ten factors-yeast extract, KH2PO4, MgSO4, FeSO4, MnCl2, CuSO4, Na2MoO4, H3BO3, ZnSO4 and pH. Cultures were grown mixotrophically under 16 h light and 8 h dark regime at 30 ºC for a period of 7 days. During the light regime, the light intensity at the surface of the vessels and agitation speed were set to 67.5 µmol photons m-2s-1 and 150 rpm, respectively. Initial cell concentration was set to an absorbance (A540 of 0.5. For high biomass production (2.2 g/L, run no. 6, the most effective and significant factors were yeast extract, KH2PO4, FeSO4 and ZnSO4 at concentrations 0.3 g/L, 0.3 g/L, 3 mg/L and 0.3 mg/L, respectively. Whereas for high lipid accumulation (19.59 %DCW, run no. 2, these were KH2PO4, pH and yeast extract, at a level of 1.7 g/L, 6.0 and 0.1 g/L, respectively. No significant factors were obtained for higher lipid content. The best treatment for biomass and lipid content was run no. 6, whose medium formula consisted of 0.3 g/L yeast extract, 1.7 g/L KH2PO4, 1.7 g/L MgSO4, 1 mg/L FeSO4, 0.9 mg/L MnCl2, and pH 7.0, together with fixed concentrations of glucose, NaHCO3 and KNO3 at 5 g/L, 0.05 g/L and 0.5 g/L, respectively.

    Full Text Available Abstract Throughout history participation in decision making through processes like voting vying for leadership position and participation in decision making meetings has been blinded by discrimination to certain groups of community members including women. This study assessed the social cultural factors affecting Maasai womens participation in decision making a case of Longido district. Purposive sampling was used to select the districts under the study. Decision to select Longido was based on the inhabitance of pastoral community. A total of 115 respondents were obtained through simple random selection. Data were collected through a questionnaire and analyzed using SPSS. Simple descriptive statistics and cross tabulation were used in the analysis. The results show that majority would you vote for a woman to be an MP Councilor Village Chairman in your community. A considerable proportion of men refused to be led by a woman. Furthermore women were found not to effectively participate in politics through vying for leadership positions as many respondents voted for male contestant main reasons being no female contestant. Situations in which women are involved in decision making were found mainly to be on issues pertaining women development and family matters. Findings show that women are allowed to vote in the community but often the decision for a woman to vote was found to be determined by men. The study further found that women are not regarded elders and females ideas were not taken into account as male ideas in village meetings. The main barriers for women participation in leadership were found that men do not want women to compete in leadership and women ideas not accepted by most men. The study concluded that Maasai women participation in decision making is limited by social cultural factors like social identity social acceptance social roles and limiting cultural practices. It is recommended that civic education strategy and appropriate

    Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. For a wound to heal successfully, all four phases must occur in the proper sequence and time frame. Many factors can interfere with one or more phases of this process, thus causing improper or impaired wound healing. This article reviews the recent literature on the most significant factors that affect cutaneous wound healing and the potential cellular and/or molecular mechanisms involved. The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds. PMID:20139336

    Full Text Available Background. Previous surveys found CAM use during menopause to be popular. This paper compares the results from two surveys (Sydney and Bologna to examine factors that determine the extent and pattern of CAM use to alleviate menopausal symptoms. Methods. Women, aged 45–65 years, who were symptomatic when transitioning through menopause or asymptomatic but taking menopause-specific treatments, were recruited in Sydney (n=1,296 and Bologna (n=1,106 to complete the same voluntary, anonymous, and self-administered questionnaire. The results were reanalysed using stratified analyses to determine similarities and differences. Results. Demographics of the two cohorts differed significantly. CAM was more popular in Sydney. The most significant determinants of CAM use were the use of CAM for other conditions besides menopause and the severity of vasomotor symptoms. Occupational status was a determinant of CAM use amongst Bologna respondents only. In order to relieve symptoms, Australian and Italian women used different CAM modalities whose effectiveness was generally perceived as good. Conclusion. CAM use is popular amongst menopausal women from Sydney and Bologna. Differences in the patterns of CAM use seem to depend on CAM availability and on the educational level and professional status of users. The complex interaction between market, social, and cultural factors of CAM use seems to be more influential on women’s choice of CAM than the available evidence of their effectiveness.

    Full Text Available The tissue culture of Phak Liang (Gnetum gnemon Linn. was investigated for micropropagation. The types of explant, culture media, types and concentrations of plant growth regulators, orientation of explant and section of explant were tested for their efficacy in inducing and proliferating shoot buds. The elongation of shoots and root induction was also studied. Young leaves gave the highest number of shoot buds when they were cultured in Murashige and Skoog (MS medium supplemented with 0.25 mg/l IBA and 1.53 mg/l BA. The medium supplemented with 0.25 mg/l thidiazuron (TDZ alone provided the best result on multiple shoot bud induction both in percentage of explant forming shoots and number of shoot buds per explant. The percentage of explant forming shoot buds and number of shoot buds obtained from leaves were 90% and 26.50 shoot buds, while those from stems were 96.25% and 23.00 shoot buds, respectively. One hundred percent friable callus was induced from stem explant in the same medium supplemented with 1.0 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D after 2 months of culture. Culturing whole leaf in the position of dorsal contact with medium gave the best multiple shoot bud formation of 92% and 23.00 shoot buds/explant. Cutting stem into half and culturing in horizontal position gave the best multiple shoot bud formation of 96% and 23.00 shoot buds/explant after culture for 2 months. The best elongation of shoot buds (2.54 shoots derived from cultured leaves was induced in the liquid medium. While stem-derived shoot buds (3.45 shoots was induced in the solid medium of the same medium components. However, root could not be induced from elongated shoots.

    Janez Kosel

    2014-01-01

    Full Text Available The paper examines the impact of ethanol, and hidroxycinnamic and vinylphenol precursors on the production of volatile phenols in fermentations of mixed and pure cultures of yeasts Saccharomyces cerevisiae and Dekkera bruxellensis. Three different D. bruxellensis strains were examined and they all showed a unique volatile phenol production pattern in the fermentations of pure and mixed cultures. Generally, the results showed that in mixed culture fermentations less vinylphenols and more ethylphenols were produced in comparison with D. bruxellensis pure culture fermentations. Vinylphenol precursors significantly inhibited the growth of S. cerevisiae and the production of ethylphenols. Nevertheless, it was found that D. bruxellensis genes encoding for enzymes coumaric acid decarboxylase (CAD and vinylphenol reductase (VPR are more responsive to vinylphenol precursors in comparison with hidroxycinnamic acids. Consequently, higher concentrations of vinylphenols in the cell were found to be more cytotoxic than hidroxycinnamic acids. In general, low ethanol concentrations induced higher production of volatile phenols by S. cerevisiae and D. bruxellensis. This was confirmed with the expression pattern of gene encoding for CAD of D. bruxellensis.

    Owing to their ubiquitous distribution, expected beneficial effects and suspected adverse effects, nanoparticles are viewed as a double-edged sword, necessitating a better understanding of their interactions with tissues and organisms. Thus, the goals of the present study were to develop and present a method to generate quantitative data on nanoparticle entry into cells in culture and to exemplarily demonstrate the usefulness of this approach by analyzing the impact of size, charge and various proteinaceous coatings on particle internalization. N9 microglial cells and both undifferentiated and differentiated SH-SY5Y neuroblastoma cells were exposed to customized gold nanoparticles. After silver enhancement, the particles were visualized by epipolarization microscopy and analysed by high-content analysis. The value of this approach was substantiated by assessing the impact of various parameters on nanoparticle uptake. Uptake was higher in microglial cells than in neuronal cells. Only microglial cells showed a distinct size preference, preferring particles with a diameter of 80 nm. Positive surface charge had the greatest impact on particle uptake. Coating with bovine serum albumin, fetuin or protein G significantly increased particle internalization in microglial cells but not in neuronal cells. Coating with wheat germ agglutinin increased particle uptake in both N9 and differentiated SH-SY5Y cells but not in undifferentiated SH-SY5Y cells. Furthermore, internalization was shown to be an active process and indicators of caspase-dependent apoptosis revealed that gold nanoparticles did not have any cytotoxic effects. The present study thus demonstrates the suitability of gold nanoparticles and high-content analysis for assessing numerous variables in a stringently quantitative and statistically significant manner. Furthermore, the results presented herein showcase the feasibility of specifically targeting nanoparticles to distinct cell types.

    An investigation carried out on 97 patients with affective disorders and on 100 healthy control subjects, revealed that acute and chronic stress factors occurred more in the group of patients with affective disorders than among healthy control over a similar time period. The frequency of stressful life situations was the same before the first affective episode in patients with unipolar and bipolar illness. The possible participation of such factors in triggering the first phase of illness is discussed. Similar factors appeared in both types of affective disorders. Significantly more frequent among patients than in the control group were: marital and family conflicts, health problems, emotional and ambitional failures, lack of success and work overload.

    2015-12-01

    Full Text Available Socio-cultural factors – shared values, norms and attitudes are significant, but less acknowledged sources of international competitiveness. Previous studies have found socio-cultural factors positively affecting various aspects of international competitiveness – entrepreneurship, innovation, productivity and international cooperation. These factors are more sustainable and less affected by external environment changes in comparison with the traditional factors. Socio-cultural factors provide an opportunity to develop competitiveness strategies based on unique advantages. This research aims to explore the impact of socio-cultural factors on international competiveness in small, open economies. Analysing relationship between 400 socio-cultural indicators and competitiveness indicators such as productivity, economic development, business and government efficiency, innovation capacity and infrastructure in 37 countries, six socio-cultural factors have emerged: Collectivism and Hierarchy; Future, Cooperation and Performance Orientation, Self-expression, Monochronism and Rationality, Economic Orientation and Social structure. The first factor – Collectivism and Hierarchy – tends to reduce the international competitiveness; the other five affect it positively.

    Full Text Available Abstract For optimal individual performance within any equestrian discipline horses must be in peak physical condition and have the correct psychological state. This review discusses the psychological factors that affect the performance of the horse and, in turn, identifies areas within the competition horse industry where current behavioral research and established behavioral modification techniques could be applied to further enhance the performance of animals. In particular, the role of affective processes underpinning temperament, mood and emotional reaction in determining discipline-specific performance is discussed. A comparison is then made between the training and the competition environment and the review completes with a discussion on how behavioral modification techniques and general husbandry can be used advantageously from a performance perspective.

    2003-05-01

    Full Text Available Factors affecting gene transformation in mangosteen (Garcinia mangostana L. were investigated. Types of explants, strains and densities of Agrobacterium tumefaciens, and co-culture methods were examined to optimize gene transformation. The results showed that among strains of Agrobacterium tumefaciens tested, LBA 4404 containing pBI 121 gave the calli with the highest resistance to kanamycin. Kanamycin at the concentration of 50-100 mg/l was the best range for selection of transformants. Higher density of agrobacteria tended to promote higher frequency of transformation. The best co-culture method was dipping the explant in a solution of agrobacteria for 10 minutes, followed by culturing onto co-culture medium without antibiotic for 48 hours. Among the explants used to co- culture with bacteria, half leaf treatment gave the best result for transformation; however, callus proliferation and plantlet regeneration were inferior to whole leaf treatment. Activity of β-Glucuronidase (GUS could not be detected, thus resistance to kanamycin was used for detecting transformability. Shoot primordia could be induced from kanamycin-resistant calli grown in regeneration medium. After maintenance by subculturing to the same medium 2 to 3 times in 2-3 months, the developed shoots turned brown and finally died. Hence, the transformed plant of mangosteen was not obtained from this experiment.

    2016-12-01

    The purpose of this study was to determine if any of the factors radiologist, examination category, time of week, and week effect PACS usage, with PACS usage defined as the sequential order of computer commands issued by a radiologist in a PACS during interpretation and dictation. We initially hypothesized that only radiologist and examination category would have significant effects on PACS usage. Command logs covering 8 weeks of PACS usage were analyzed. For each command trace (describing performed activities of an attending radiologist interpreting a single examination), the PACS usage variables number of commands, number of command classes, bigram repetitiveness, and time to read were extracted. Generalized linear models were used to determine the significance of the factors on the PACS usage variables. The statistical results confirmed the initial hypothesis that radiologist and examination category affect PACS usage and that the factors week and time of week to a large extent have no significant effect. As such, this work provides direction for continued efforts to analyze system data to better understand PACS utilization, which in turn can provide input to enable optimal utilization and configuration of corresponding systems. These continued efforts were, in this work, exemplified by a more detailed analysis using PACS usage profiles, which revealed insights directly applicable to improve PACS utilization through modified system configuration.

    Full Text Available AIM: This study was performed to determine the psychological factors affecting infertile women presenting at the infertility outpatients department. METHOD: The sample of this cross-sectional study consisted of 344 women who presented at the IVF center of a special branch hospital or a university hospital, March 2008 through September 2008, as determined by the non-random sampling method. All participating women gave their informed consent. The data were collected using the Data Form that consisted of questions on socio-demographic features and the Infertility Distress Scale (IDS. In the results, percentages were provided along with the Kruskal-Wallis H, Mann-Whitney U and Spearman correlation tests. RESULTS: The mean IDS was 39.01±9.6. There was a statistically significant linear relationship between the mean IDS score and age (r=0.106, p=0.048, marriage duration (r=0.232, p<0.001 and duration of desire to have a child (r=0.217, p<0.001. Women who were primary school graduates (X²=13.03, p=0.004, did not work (p=0.007, had no social security benefits (p=0.021 or from low socioeconomic status (X²=24.85, p<0.001 had significantly higher mean IDS scores. CONCLUSION: The results of this study show women become more adversely affected by infertility as their age, duration of marriage, and duration of desire to have a child increase. Women who are primary school graduates, do not work, have no social security benefits or have lower income are affected more negatively. We believe that taking these features into account when evaluating and planning supportive approaches for women presenting at the infertility treatment center and determining the psychological state of the women using the IDS will increase treatment success.

  18. Micro and macro factors affecting childbearing aspirations.

    Science.gov (United States)

    He, Y

    1992-01-01

    The conclusion of the discussion of factors affecting childbearing aspirations is that both a micro and a macro perspective must be included in an empirical analysis which would be useful for policy decisions. Micro factors tend to the economic function of the family, the economic value of children, cost of labor training, women's occupation, social security, household consumption, and education level. Attention to micro factors is important in the link between individual interests and state family planning (FP) policy. Macro factors tend to be ignored, but also impact on childbearing decisions. Macro factors are economic conditions, social and political factors, culture, and environmental factors such as ecology, natural resources, employment, economic development, and education. Macro factors affect the population as a whole and indirectly impact on individuals and the family. China's achievements in FP policy have been identified as a reduction of 200 million people, a shift in the population reproduction cycle downwards, increased standard of living, reduction in the burden of working people, and stabilization of macro factors. Successful policy should not rely on forced implementation. The past and present policies were successful not because of forced implementation, but because of awareness of macro and micro factors and voluntary use of FP. The voluntary nature of acceptance of FP suggests support for the FP policies. The current focus is on rural areas, and farmers in particular who are only aware of their needs and may feel state policy may interfere with their own interests. Implementation of FP among the rural population would be enhanced with an emphasis on their concerns such as social security in old age, the practical issues of having only daughters, and educational status. Educational campaigns promoting awareness of population pressure are needed and will benefit all the people. Social democratic doctrines can be introduced only from the outside

    Craig, J C; Kisner, J M

    1998-01-01

    Tactile spatial acuity on the fingerpad was measured using a grating orientation task. In this task, subjects are required to identify the orientation of square-wave gratings placed on the skin. Previous studies have shown that performance varies as a function of the width of the grooves in the gratings. In the present study, both groove width and the overall size and configuration of the contactors were varied. Sensitivity improved with wider grooves and with larger contactors. Additional measurements showed that the improved sensitivity is not the result of the increase in total area contacted, but rather is due to two other factors associated with larger contactors. One is the greater linear extent of the larger contactors. The other appears to be due to the reduction in the interference produced by the outer edge of the contactor. Specifically, as the contactor increases in size, the distance between the outer edge and the center portion of the grooves also increases. It was also shown that subjects are more sensitive to a single, continuous groove as compared with two grooves of the same total length but spatially discontinuous. Similarly, subjects are more sensitive to a contactor with a continuous groove than to a contactor in which just the end points of the groove are presented. The results are generally consistent with the results of peripheral, neurophysiological recordings. The results are discussed in terms of the way in which both spatial and intensive factors may affect sensitivity to grating orientation.

    Measuring dental clinic service quality is the first and most important factor in improving care. The quality provided plays an important role in patient satisfaction. The purpose of this paper is to identify factors affecting dental service quality from the patients' viewpoint. This cross-sectional, descriptive-analytical study was conducted in a dental clinic in Tehran between January and June 2014. A sample of 385 patients was selected from two work shifts using stratified sampling proportional to size and simple random sampling methods. The data were collected, a self-administered questionnaire designed for the purpose of the study, based on the Parasuraman and Zeithaml's model of service quality which consisted of two parts: the patients' demographic characteristics and a 30-item questionnaire to measure the five dimensions of the service quality. The collected data were analysed using SPSS 21.0 and Amos 18.0 through some descriptive statistics such as mean, standard deviation, as well as analytical methods, including confirmatory factor. Results showed that the correlation coefficients for all dimensions were higher than 0.5. In this model, assurance (regression weight=0.99) and tangibility (regression weight=0.86) had, respectively, the highest and lowest effects on dental service quality. The Parasuraman and Zeithaml's model is suitable to measure quality in dental services. The variables related to dental services quality have been made according to the model. This is a pioneering study that uses Parasuraman and Zeithaml's model and CFA in a dental setting. This study provides useful insights and guidance for dental service quality assurance.

    Full Text Available This study aimed to examine key factors affecting rural female facilitators’ role in participatory rural developmentin Tehran Province. Since the researchers intended to have abetter insight into the facilitators’ role and employ inquiry as alearning forum for bringing about changes for all participants,they preferred to use a case study based upon an appreciativeinquiry method. The study divided the factors affecting thefacilitators’ role into two main categories: driving factors andpreventing factors. The former are: two-way communication,election of rural eligible facilitators, participation, sense ofresponsibility, and the latter are: cultural and tribal fanaticism,lack of permanent female extension workers and frequentmanagement changes. Appreciative inquiry as a positive modeof action research could facilitate the process of education andcommunication for all stakeholders. We suggested that thereshould be a shift from the extension as a knowledge transfer tofacilitation as people’s own knowledge creation. This studyshowed that appreciative inquiry could facilitate the process ofchange and gender-awareness. This research method couldalso facilitate mutual communication between the rural facilitatorsand extension workers.

    Rapid industrial and economic growth has meant a large amount of aerosols in the atmosphere with strong radiative forcing (RF) upon the climate system. Over parts of the globe, the negative forcing of aerosols has overcompensated for the positive forcing of greenhouse gases. Aerosol RF is determined by emissions and various chemical-transport-radiative processes in the atmosphere, a multi-factor problem whose individual contributors have not been well quantified. In this study, we analyze the major factors affecting RF of secondary inorganic aerosols (SIOAs, including sulfate, nitrate and ammonium), primary organic aerosol (POA), and black carbon (BC). We analyze the RF of aerosols produced by 11 major regions across the globe, including but not limited to East Asia, Southeast Asia, South Asia, North America, and Western Europe. Factors analyzed include population size, per capita gross domestic production (GDP), emission intensity (i.e., emissions per unit GDP), chemical efficiency (i.e., mass per unit emissions) and radiative efficiency (i.e., RF per unit mass). We find that among the 11 regions, East Asia produces the largest emissions and aerosol RF, due to relatively high emission intensity and a tremendous population size. South Asia produce the second largest RF of SIOA and BC and the highest RF of POA, in part due to its highest chemical efficiency among all regions. Although Southeast Asia also has large emissions, its aerosol RF is alleviated by its lowest chemical efficiency. The chemical efficiency and radiative efficiency of BC produced by the Middle East-North Africa are the highest across the regions, whereas its RF is lowered by a small per capita GDP. Both North America and Western Europe have low emission intensity, compensating for the effects on RF of large population sizes and per capita GDP. There has been a momentum to transfer industries to Southeast Asia and South Asia, and such transition is expected to continue in the coming years. The

    Although measures of cultural identity, values, and behavior exist in the multicultural psychological literature, there is currently no measure that explicitly assesses ethnic minority individuals' positive and negative affect toward culture. Therefore, we developed 2 new measures called the Feelings About Culture Scale--Ethnic Culture and Feelings About Culture Scale--Mainstream American Culture and tested their psychometric properties. In 6 studies, we piloted the measures, conducted factor analyses to clarify their factor structure, and examined reliability and validity. The factor structure revealed 2 dimensions reflecting positive and negative affect for each measure. Results provided evidence for convergent, discriminant, criterion-related, and incremental validity as well as the reliability of the scales. The Feelings About Culture Scales are the first known measures to examine both positive and negative affect toward an individual's ethnic culture and mainstream American culture. The focus on affect captures dimensions of psychological experiences that differ from cognitive and behavioral constructs often used to measure cultural orientation. These measures can serve as a valuable contribution to both research and counseling by providing insight into the nuanced affective experiences ethnic minority individuals have toward culture.

  13. Column: Factors Affecting Data Decay

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available In nuclear physics, the phrase decay rate is used to denote the rate that atoms and other particles spontaneously decompose. Uranium-235 famously decays into a variety of daughter isotopes including Thorium and Neptunium, which themselves decay to others. Decay rates are widely observed and wildly different depending on many factors, both internal and external. U-235 has a half-life of 703,800,000 years, for example, while free neutrons have a half-life of 611 seconds and neutrons in an atomic nucleus are stable.We posit that data in computer systems also experiences some kind of statistical decay process and thus also has a discernible decay rate. Like atomic decay, data decay fluctuates wildly. But unlike atomic decay, data decay rates are the result of so many different interplaying processes that we currently do not understand them well enough to come up with quantifiable numbers. Nevertheless, we believe that it is useful to discuss some of the factors that impact the data decay rate, for these factors frequently determine whether useful data about a subject can be recovered by forensic investigation.(see PDF for full column

  14. Factors affecting protoplast electrofusion efficiency.

    Science.gov (United States)

    Nea, L J; Bates, G W

    1987-10-01

    The electrofusion efficiency of protoplasts isolated from a carrot (Daucus carota) suspension culture was increased by treatment with 0.1 mg/ml lysolecithin, 2.5% dimethylsulfoxide (DMSO), or 0.5 mM Ca(2+). The lysolecithin and DMSO treatments substantially increased protoplast lysis, whereas calcium treatment did not. The enzymes used for protoplast isolation were also found to have a dramatic effect on the efficiency of fusion. A mixture of Cellulysin and Driselase led to a two-fold enhancement of fusion as compared with Driselase alone. The stimulation by Cellulysin appears to be due to enzymatic modification of the cell surface. However, comparison of the time course for wall digestion with the development of susceptibility to electrofusion suggests that the effect of Cellulysin is not simply due to removal of the cell wall. Brief treatment of the cells with pronase or proteinase K also doubled the efficiency of fusion. Taken together, these results indicate that electrofusion efficiency can be enhanced by the method used for protoplast isolation; they also suggest that modification of membrane/cell-surface proteins during protoplast isolation may be particularly important in determining electrofusion efficiencies.

    Ex vivo expansion of hematopoietic cells is important for applications such as cancer treatment, gene therapy, and transfusion medicine. While cell culture systems are widely used to evaluate the biocompatibility of materials for implantation, the ability of materials to support proliferation of primary human cells in cultures for reinfusion into patients has not been addressed. We screened a variety of commercially available polymer (15 types), metal (four types), and glass substrates for their ability to support expansion of hematopoietic cells when cultured under conditions that would be encountered in a clinical setting. Cultures of peripheral blood (PB) CD34+ cells and mononuclear cells (MNC) were evaluated for expansion of total cells and colony-forming unit-granulocyte monocyte (CFU-GM; progenitors committed to the granulocyte and/or monocyte lineage). Human hematopoietic cultures in serum-free medium were found to be extremely sensitive to the substrate material. The only materials tested that supported expansion at or near the levels of polystyrene were tissue culture polystyrene, Teflon perfluoroalkoxy, Teflon fluorinated ethylene propylene, cellulose acetate, titanium, new polycarbonate, and new polymethylpentene. MNC were less sensitive to the substrate materials than the primitive CD34+ progenitors, although similar trends were seen for expansion of the two cell populations on the substrates tested. CFU-GM expansion was more sensitive to substrate materials than was total cell expansion. The detrimental effects of a number of the materials on hematopoietic cultures appear to be caused by protein adsorption and/or leaching of toxins. Factors such as cleaning, sterilization, and reuse significantly affected the performance of some materials as culture substrates. We also used PB CD34+ cell cultures to examine the biocompatibility of gas-permeable cell culture and blood storage bags and several types of tubing commonly used with biomedical equipment

    Chemical compounds are produced every day, many with adverse effects on human health, and hence it is vital to predict the risks to humans simply, rapidly, and accurately. Teratogens have a serious impact on fetal development. This has been studied mainly by phenotypic analysis of experimental animals. However, since phenotypes can vary within different species, we established a new evaluation system based on our recent finding that teratogens influence Hox gene expression in mice. Similarly to the Hox gene expression changes, the expression patterns of several transcription factors involved in development, including the Dlx, Irx, Sall, and T-box families, were altered after 6 h of exposure to retinoic acid (RA) or 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The expression changes in Dlx4, Dlx6, Irx5, Sall2, Sall3, Sall4, Tbx10, and Tbx22 were linked to teratogen-induced phenotypes, and our results indicate that expression changes in developmental transcription factors can help to predict teratogenic risk.

    1998-01-01

    Full Text Available Significant advances have been made in our knowledge of forage seed physiology, technology, and stand establishment practices; however, stand establishment continues to be one of the most common production problems affecting forage crops in the USA. There is a need for research on stand establishment of forage crops under abiotic and biotic stress. Although the forage seed industry produces and markets seed of high quality, new methods of assessing seed vigor are needed and their use should be expanded in the industry to enable matching seed lot performance to specific environmental conditions where performance can be maximized. Seed treatment and seed coating are used in the forage seed industry, and studies have shown they are of benefit in some environments. There is an increase in no-tillage seeding of forage crops, but improvements in the no-tillage planting equipment are needed to make them better suited to small seeds. Other recent developments in seeding techniques include broadcasting seed with dry granular and fluid fertilizers, which improves the efficiency of the seeding operation.

  1. Factors affecting calculation of L

    Ciotola, Mark P.

    2001-08-01

    A detectable extraterrestrial civilization can be modeled as a series of successive regimes over time each of which is detectable for a certain proportion of its lifecycle. This methodology can be utilized to produce an estimate for L. Potential components of L include quantity of fossil fuel reserves, solar energy potential, quantity of regimes over time, lifecycle patterns of regimes, proportion of lifecycle regime is actually detectable, and downtime between regimes. Relationships between these components provide a means of calculating the lifetime of communicative species in a detectable state, L. An example of how these factors interact is provided, utilizing values that are reasonable given known astronomical data for components such as solar energy potential while existing knowledge about the terrestrial case is used as a baseline for other components including fossil fuel reserves, quantity of regimes over time, and lifecycle patterns of regimes, proportion of lifecycle regime is actually detectable, and gaps of time between regimes due to recovery from catastrophic war or resource exhaustion. A range of values is calculated for L when parameters are established for each component so as to determine the lowest and highest values of L. roadmap for SETI research at the SETI Institute for the next few decades. Three different approaches were identified. 1) Continue the radio search: build an affordable array incorporating consumer market technologies, expand the search frequency, and increase the target list to 100,000 stars. This array will also serve as a technology demonstration and enable the international radio astronomy community to realize an array that is a hundred times larger and capable (among other things) of searching a million stars. 2) Begin searches for very fast optical pulses from a million stars. 3) As Moore's Law delivers increased computational capacity, build an omni-directional sky survey array capable of detecting strong, transient

    2009-10-01

    This paper aims to provide conceptual justifications for the inclusion of culture and cultural factors in psychiatric diagnosis, and logistic suggestions as to the content and use of this approach. A discussion of the scope and limitations of current diagnostic practice, criticisms from different quarters, and the role and relevance of culture in the diagnostic encounter, precede the examination of advantages and disadvantages of the approach. The cultural content of psychiatric diagnosis should include the main, well-recognized cultural variables, adequate family data, explanatory models, and strengths and weaknesses of every individual patient. The practical aspects include the acceptance of "cultural discordances" as a component of an updated definition of mental disorder, and the use of a refurbished cultural formulation. Clinical "telescoping" strategies to obtain relevant cultural data during the diagnostic interview, and areas of future research (including field trials on the cultural formulation and on "culture bound syndromes"), are outlined.

  3. Job Satisfaction Affecting Cross-Cultural Adjustment in Taiwanese Expatriates

    2014-09-01

    Full Text Available By means of the increasing global competition and internationalization of world markets, international expatriates assignments are more and more essential to successful worldwide development for many multinational corporations. Therefore, international expatriates are imperative to the survival of globe enterprises in the twenty-first century. Expatriates can become an important human resource to international enterprises or multinational operations. Also, for the past two decades, research has examined a variety of correlates for the performance problems and dissatisfaction associated with global assignment. To facilitate business expatriates adjust to an overseas environment and work effectively, Multinational Corporations (MNCs need to recognise the expatriates’ job satisfaction factor to affect cross-cultural adjustment. The main purpose of this study is utilising previous researcher Lee’s (2002 questionnaire to investigate the relationship between the job satisfaction and cross-cultural adjustment of Taiwanese Banks’ expatriates assigned to America, and this study employed same questionnaire to examine the relationship between the job satisfaction and cross-cultural adjustment of Taiwanese expatriates in several different industries assigned to Mainland China. Also, the empirical outcomes were compared between Taiwanese expatriates located in Mainland China and United States.In examining the significant degree of Taiwanese expatriates assigned to Mainland China, the instrument was a questionnaire survey conducted to this study. The variables of interest were measured using items Likert-type questions, and those items are divided into seven categories. Data collected from 353 participants who have experience of a posting to Mainland China for international assignments. Multiple regression and correlation were employed to analyse data.The statistical results of this study were compared Lee’s (2002 research that associated with

  4. How adoption speed affects the abandonment of cultural tastes.

    Berger, Jonah; Le Mens, Gaël

    2009-05-19

    Products, styles, and social movements often catch on and become popular, but little is known about why such identity-relevant cultural tastes and practices die out. We demonstrate that the velocity of adoption may affect abandonment: Analysis of over 100 years of data on first-name adoption in both France and the United States illustrates that cultural tastes that have been adopted quickly die faster (i.e., are less likely to persist). Mirroring this aggregate pattern, at the individual level, expecting parents are more hesitant to adopt names that recently experienced sharper increases in adoption. Further analysis indicate that these effects are driven by concerns about symbolic value: Fads are perceived negatively, so people avoid identity-relevant items with sharply increasing popularity because they believe that they will be short lived. Ancillary analyses also indicate that, in contrast to conventional wisdom, identity-relevant cultural products that are adopted quickly tend to be less successful overall (i.e., reduced cumulative adoption). These results suggest a potential alternate way to explain diffusion patterns that are traditionally seen as driven by saturation of a pool of potential adopters. They also shed light on one factor that may lead cultural tastes to die out.

  10. Ammonia Affects Astroglial Proliferation in Culture.

    Directory of Open Access Journals (Sweden)

    Guillermo Bodega

    Full Text Available Primary cultures of rat astroglial cells were exposed to 1, 3 and 5 mM NH4Cl for up to 10 days. Dose- and time-dependent reductions in cell numbers were seen, plus an increase in the proportion of cells in the S phase. The DNA content was reduced in the treated cells, and BrdU incorporation diminished. However, neither ammonia nor ammonia plus glutamine had any effect on DNA polymerase activity. iTRAQ analysis showed that exposure to ammonia induced a significant reduction in histone and heterochromatin protein 1 expression. A reduction in cell viability was also noted. The ammonia-induced reduction of proliferative activity in these cultured astroglial cells seems to be due to a delay in the completion of the S phase provoked by the inhibition of chromatin protein synthesis.

    2010-01-01

    Based on the introduction of factors affecting the income level of farmers in China,a total of 31 provinces,autonomous regions and municipality cities are taken as samples to select 13 factors affecting the income level of farmers,which are arable land area(X1),disaster area(X2),effective irrigation area(X3),fertilizer application(X4),mobile phone(X5),personal computer(X6),people joining in the new rural cooperative medical care(X7),rural investment(X8),household-use machine(X9),agricultural product price(X10),proportion of labor force with above junior high school education(X11),rural delivery route(X12),and rural electricity consumption(X13).At the same time,factor analysis method is used to analyze the factors affecting the income level of farmers.Result shows that common factors affecting the income of farmers are the agricultural production factor F1,the expanded reproduction factor F2,the information use factor F3,and the output reduction factor F4.At present,education degree of farmers and ability of farmers in grasping information have relatively great impact on the income of farmers,and can effectively promote the income growth of farmers.Scores of F1 in Henan,Shandong and Hebei are generally higher;Jiangsu,Guangdong,Zhejiang and Shandong Provinces have relatively high scores of F2;Shanghai,Beijing and Guangdong have relatively high scores of F3;and Hunan,Hubei and Xinjiang have relatively high scores of F4.Finally,countermeasures are put forward to improve the income of farmers based on empirical study.

  16. Factors Affecting the Productivity of Government Workers

    Jerry P. Haenisch

    2012-01-01

    Full Text Available While there have been a variety of studies concerning government worker motivation and productivity, few, if any, studies have focused specifically on state government workers’ perceptions about what factors affect their productivity. With more than 5 million workers employed by state governments in the United States, any improvement in state workplace productivity could have significant financial and service impact for society. In this study, state government workers identified those factors perceived as most affecting their workplace productivity. Data were collected through a survey offered to state government workers in the state of Wyoming. Factor analysis was used to derive key productivity factors from survey responses. The results indicate that state government workers appreciate having freedom and autonomy, like their jobs and the sense of achievement, and welcome teamwork, but feel limited by poor supervision and management, poor communications, and insufficient budgets and staffing. To improve productivity, the workers would eliminate bureaucracy, supervise better, and improve communication.

    It is one thing that currently in China English learning persists through a student's whole study life, but it is another how long his persistence, an important factor in any language learning, can last. The factors affecting a student's persistence in this regard practically merits our attention. This paper traces and observes twenty students chosen by random. The research conducted here included their study motivation, academic excellence, psychological aspects relating to language learning and established corresponding models showing how these factors affect a student's persistence in his English learning. Although a small sample number was taken,of different students in China.the twenty students were typical of different students in China. The students' backgrounds were varied including both educational and environmental. Some suggestions are given indicating three separate but inter-related ways in how to further develop a student's persistence.

  1. Comment: Affect Control Theory and Cultural Priming: A Perspective from Cultural Neuroscience.

    Affect control theory posits that emotions are constructed by social and cultural forces. Rogers, Schröder, and von Scheve (2014) introduce affect control theory as a conceptual and methodological "hub," linking theories from different disciplines across levels of analysis. To illustrate this further, we apply their framework to cultural priming, an experimental technique in cultural psychology and neuroscience for testing how exposure to cultural symbols (e.g., words and pictures) changes people's behavior, cognition, and emotion. Our analysis supports the use of affect control theory in linking different levels of analysis while leaving some opening questions for improving such a framework in future research.

    Full Text Available Cell-based therapy has been explored for articular cartilage regeneration. Autologous chondrocyte implantation is a promising cell-based technique for repairing articular cartilage defects. However, there are several issues such as chondrocyte de-differentiation. While numerous studies have been designed to overcome some of these issues, only a few have focused on the thermal environment that can affect chondrocyte metabolism and phenotype. In this study, the effects of different culture temperatures on human chondrocyte metabolism- and phenotype-related gene expression were investigated in 2D and 3D environments. Human chondrocytes were cultured in a monolayer or in a pellet culture system at three different culture temperatures (32°C, 37°C, and 41°C for 3 days. The results showed that the total RNA level, normalized to the threshold cycle value of internal reference genes, was higher at lower temperatures in both culture systems. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH and citrate synthase (CS, which are involved in glycolysis and the citric acid cycle, respectively, were expressed at similar levels at 32°C and 37°C in pellet cultures, but the levels were significantly lower at 41°C. Expression of the chondrogenic markers, collagen type IIA1 (COL2A1 and aggrecan (ACAN, was higher at 37°C than at 32°C and 41°C in both culture systems. However, this phenomenon did not coincide with SRY (sex-determining region Y-box 9 (SOX9, which is a fundamental transcription factor for chondrogenesis, indicating that a SOX9-independent pathway might be involved in this phenomenon. In conclusion, the expression of chondrocyte metabolism-related genes at 32°C was maintained or enhanced compared to that at 37°C. However, chondrogenesis-related genes were further induced at 37°C in both culture systems. Therefore, manipulating the culture temperature may be an advantageous approach for regulating human chondrocyte metabolic activity and

    Full Text Available The external factors influencing the process of formation of tariffs of commercial services are considered in the article. External environment is known to be very diverse and changeable. Currently, pricing has become one of the key processes of strategic development of a company. Pricing in the service sector, in turn, is highly susceptible to changes in the external environment. Its components directly or indirectly affect the market of services, changing it adopted economic processes. As a rule, firms providing services can’t influence the changes in external factors. However, the service market is very flexible, which enables businesses to reshape pricing strategy, to adapt it to the new environment.

    Full Text Available The current study was carried out to evaluate the quantity and quality of rural domestic waste generation and to identify the factors affecting it in rural areas of Khodabandeh county in Zanjan Province, Iran. Waste samplings consisted of 318 rural households in 11 villages. In order to evaluate the quality and quantity of the rural domestic waste, waste production was classified into 12 groups and 2 main groups of organic waste and solid waste. Moreover, kriging interpolation technique in ARC-GIS software was used to evaluate the spatial distribution of the generated domestic waste and ultimately multiple regression analysis was used to evaluate the factors affecting the generation of domestic waste. The results of this study showed that the average waste generated by each person was 0.588 kilograms per day. with the share of organic waste generated by each person being 0.409 kilograms per day and the share of solid waste generated by each person being 0.179 kilograms per day. The results from spatial distribution of waste generation showed a certain pattern in three groups and a higher rate of waste generation in the northern and northwestern parts, especially in the subdistrict. The results of multiple regression analysis showed that the households’ income, assets, age, and personal attitude are respectively the most important variables affecting waste generation. The housholds’ attitude and indigenous knowledge on efficient use of materials are also the key factors which can help reducing waste generation.

    To systematically identify the main factors contributing to the increase in pharmaceutical expenditures. A systematic search of published studies was conducted utilising major widely used electronic databases using the search terms 'factors,' 'financing,' 'pharmaceutical,' and 'expenditures.' To be included, the studies needed to: (1) measure at least one of the following outcomes: total growth in pharmaceutical expenditures, price growth or quantity growth; (2) mention a clear method for analysing the impact of factors affecting the increases in drug expenditures; (3) be written in English. Nonprimary articles that were published only as an abstract, a review, a commentary or a letter were excluded. From a total of 2039 studies, only 25 were included in the full review. The main determinant categories that were identified in the review were factors related to price, utilisation, therapeutic choice, demand and health care system. The major cost drivers were found to be changes in drug quantities and therapies as well as new drugs. It is important for policymakers to understand pharmaceutical spending trends and the factors that influence them in order to formulate effective cost containment strategies and design optimum drug policy.

    Sikov, M.R.; Kelman, B.J. (Pacific Northwest Laboratory, Richland, WA (USA))

    1989-01-01

    The primary goal of this paper is to consider factors that affect the availability and transport of actinides from maternal blood, through the placenta, to the conceptus. These factors, of particular importance in scaling results from animals to man, include the route and temporal pattern of administration, the mass and physicochemical state of material administered, metabolism of the pregnant animal and fetal organs or tissue, and species-specific changes in placental structure relative to stage of gestation at exposure. Preliminary concepts for descriptive and kinetic models are proposed to integrate these results, to identify additional information required for developing more comprehensive models, and to provide a basis for scaling to human pregnancies for purposes of radiation dosimetry.

    2017-03-01

    Full Text Available Community Supported Agriculture (CSA is one of the widely used direct marketing strategies for small- and midsized farmers. CSA programs are an important option for sustainable production and consumption. It helps growers generate income (improve financial security and consumers obtain fresh local foods. Sustaining and growing CSA participation is critical in order to continue enjoying these benefits. We used a national online survey in conjunction with discrete choice models to investigate the impact of demographic characteristics, lifestyle preferences, and different information outlets on the probability that a consumer is or will become a CSA member. The results indicate that the factors affecting current and future CSA participation differ substantially. While none of the demographic characteristics has a significant impact on current CSA participation, some of them significantly affect the probability that a consumer will become a CSA member in the future. Lifestyle preferences have a significant impact on current and future CSA participation. Although none of the information outlets examined affect current CSA participation, word-of-mouth and online sources significantly influence the probability that a consumer will join a CSA program in the future. These findings may have important implications for policy makers’ and CSA farm managers’ efforts to sustain future CSA development.

    2015-01-01

    Purpose: To investigate the correlation of various corneal hysteresis (CH) factors in Chinese adults. Methods: From January 2009 to November 2011, the healthy right eyes of a total of 292 adults were recruited into the study. Goldmann-correlated intraocular pressure (IOPG) and CH were measured using an ocular response analyzer (ORA). Central corneal thickness was measured using the ORA’s in-tegrated handheld ultrasonic pachymeter. The IOLMaster was used to obtain the ocular biometric measurements including axial length, anterior chamber depth, and keratometric values. The Pearson correlation coefficient was used to test correla-tions between CH and quantitative factors. The chi-square test was used to detect differences in categorical values. Results: Longer axial length (P=0.0001), lower IOPG (P=0.03), older age(P=0.003),and thinner central corneal thick-ness (P=0.0001) were significantly associated with lower CH. The anterior chamber depth (P=0.34), gender (P=0.23), and corneal curvature (P=0.18) had no relationship to CH. Conclusion:Various factors including axial length, intraocular pressure, age, and central corneal thickness can affect measure-ment of corneal biomechanical properties in Chinese adults. But the anterior chamber depth, gender, and corneal curvature were irrelevant to CH.

    Opal, S; Garg, S; Jain, J; Walia, I

    2015-03-01

    This article reviews the literature on genetic aspects of dental caries and provides a framework for the rapidly changing disease model of caries. The scope is genetic aspects of various dental factors affecting dental caries. The PubMed database was searched for articles with keywords 'caries', 'genetics', 'taste', 'diet' and 'twins'. This was followed by extensive handsearching using reference lists from relevant articles. The post-genomic era will present many opportunities for improvement in oral health care but will also present a multitude of challenges. We can conclude from the literature that genes have a role to play in dental caries; however, both environmental and genetic factors have been implicated in the aetiology of caries. Additional studies will have to be conducted to replicate the findings in a different population. Identification of genetic risk factors will help screen and identify susceptible patients to better understand the contribution of genes in caries aetiopathogenesis. Information derived from these diverse studies will provide new tools to target individuals and/or populations for a more efficient and effective implementation of newer preventive measures and diagnostic and novel therapeutic approaches in the management of this disease.

    Full Text Available Problem statement: Layer hen enterprises suffer from low profitability or losses in many of developing countries all over the world. Jordan is not an acceptance. Approach: This study aimed at investigating the influence of ten main factors affecting the profitability of layer hen producers. The investigated factors include price of purchased pullet, feed price, cost of labor, cost of veterinary service and medicine, building and machinery depreciation, repairs and maintenance and miscellaneous costs, length of production cycle, feed conversion ratio, mortality rate, egg sale price and laying percentage. Results: The study used a multiple regression profit model to estimate the effect of the above mentioned factors on profit per kg egg produced. The direction and quantity of relationship between profit per kg egg and variables affecting profit were investigated. Data from 40 operating and randomly selected egg production enterprises in the country was collected. Data was obtained directly from the producers during April to mid August 2010. Semi structured interviews were conducted with a pre-tested questionnaire. The data obtained via interview surveys were processed to calculate profit per kg egg and other relevant information for inclusion in a profit function model. Fifteen eggs are registered to be 1 kg in the study. Cost and income items used to calculate profit in the study. The results of the study revealed that the feed price was found to be the factor which has the highest negative impact on the profitability showing the coefficient-3.01. The egg sale price was with high positive impact on profitability showing the coefficient 2.633. Conclusion/Recommendations: From the results of the study it could be concluded that higher prices of purchased or breeding pullet, higher feed price, higher cost of labor, higher cost of veterinary service and medicine, higher other costs including building and machinery depreciation, repairs and

    Clarissa C. David

    2014-12-01

    Full Text Available Factors affecting fertility desires in the Philippines were examined using data from a national survey and from individual and group qualitative interviews involving 143 respondents. Fertility goals usually range from two to three children, but evidence suggests that they are dynamic and may change over a person’s lifetime. Qualitative interviews reveal that when negotiating about family size, it is the partner who wants more children that will be followed. A strong demand for gender balance among offspring creates a willingness to have more children than originally desired. Fertility goals increase over time among women. While those who start childbirth at a very young age successfully space their children, they tend to want larger families than those who start late. Initial fertility goals among women are generally low but may increase because of higher fertility desires among men, a demand for gender balance in children, and the desire for babies once their children have grown.

    To establish health-related reasons behind Canadian food choices, and how variables such as education, income, gender, ethnicity and age may affect food selection. Approximately 98 733 Canadians responded to the 12 questions regarding food choices in the Canadian Community Health Survey (CCHS) cycle 2.1, conducted by the Canadian Government in 2003. These included 13 727 adolescents (12-19 years), 19 089 young adults (20-34 years), 31 039 middle-aged adults (35-54 years), 25 338 older adults (55-74 years) and 9580 elderly (75+ years). Approximately 70% of Canadian adolescents in the sample indicated that their food choices were independent of health concerns. Body weight management was a major concern for food selection by adolescents and adults, while the elderly stated heart disease as their main concern. Among all participants, females, and individuals with high levels of education and income reported the highest response to choosing or avoiding foods due to health concerns and food content. Our data indicate that several factors significantly affect food choices for health-related reasons in the Canadian population. Among them, age- and gender-related gaps, particularly between adolescents and adults, are profound. This observation may urge authorities to implement effective strategies to educate Canadians, especially adolescents, that selection of appropriate foods may prevent chronic diseases.

    Full Text Available Outdoor leisure activities are important for public health as well as family cohesiveness, yet environmental factors may easily affect someone’s ability to participate in such activities. We explored this with a focus on the social web-based treasure hunt game called Geocaching. We collected data on all US and Canadian geocaches from OpenCaching.com and conducted an online survey with twenty geocachers as a follow-up to our data analysis. Data analysis showed that geocaches were more often found in areas that were wealthier, better educated, younger, and more urban, and had higher population density and better weather. Survey results showed similar trends: Most people actively thought about where they would cache and tried to minimize risks, despite cache hiders thinking less about these concerns. These results further emphasize the importance of environmental factors when it comes to participation in outdoor activities and leads to Human–Computer Interaction design implications for location-based online social activities.

    Full Text Available Absorption of drugs from the gastrointestinal tract is a complex process the variability of which is influenced by many physicochemical and physiologic factors. The two most important physicochemical factors that affect both the extent and the rate of absorption are lipophilicity and solubility. The rate and extent of absorption are governed by the solubility, permeability and stability of the drug, with solubility being a pH-dependent parameter for weak acids and bases. The gastrointestinal tract can be viewed as discrete sections with a variety of differential local pH environments ranging from the acidic stomach to the more basic small intestine. The multiple peaking, double peaking or secondary peaking phenomena can occur in the disposition of a variety of xenobiotics during drug development (the pre-clinical phase and in subsequent clinical studies and use. The physicochemical and physiological mechanisms underlying the occurrence of this phenomenon are often multi factorial and include but are not limited to solubility-limited absorption, modified-release formulations, complexation, enterohepatic recirculation, gastric emptying and the intestinal transit time, site-specific absorption, gastric secretion-enteral reabsorption. Double peak absorption has been described with several orally administered drugs such as cimetidine furosemide, piroxicam, ranitidine, talinolol, alprazolam and phenazopyridine.

    Full Text Available This study was undertaken to identify the factors affecting sugarcane production in Pakistan. Data were collected from 387 sugarcane growers from Sindh, Punjab and NWFP province. Data were collected during the period 2007-08. The study reveals that the costs of inputs of sugarcane i.e. urea, DAP, FYM, land preparation, seed and its application, weeding and cost of irrigation were the important factors which influenced on the returns of sugarcane growers. The effectiveness was examined by using the Cobb-Douglas production function; MVP and allocative efficiency were calculated. The coefficient of multiple determinations R2 was 0.9249, which indicated that 92% variation in the cost of inputs was explained by all explanatory variables and the adjusted R2 was 92%. The F-value was 666.94 and was highly significant at 5% level of significance, indicating that the regression model was well fitted. The high prices of inputs, low price of output, delay in payments and lack of scientific knowledge were the major problems in sugarcane production. In order to enhance the productivity of sugarcane in the country, government should solve the identified problems to increase the income of sugarcane growers.

    Full Text Available Currently Lithuania has an old-age pension system of three pillars. Unfortunately, when making an investment decision, too few factors are used that affect strategy effectiveness. It is necessary to develop tools to better assess the risks and more accurately simulate the potential long-term investment scenarios. The article deals with the investment strategy to the second and third pillar pension funds in order to maximize investment returns and reduce risks. A smart software tool allows you to simulate an accrual depending on the rate of return, the accumulation period, the level of contributions, the fund’s profitability and other factors. The study shows that using the Social Insurance Fund contributions, personal contributions and the state provided additives can accumulate significantly greater amounts of money than collecting only the second pillar pension funds contributions. For implementation of the proposed methodology it is necessary to ensure a minimum level of personal pension scheme members fundraising to the third pillar pension funds. On the other hand, the study revealed that in some cases investment to private pension funds can be useless. Private pension funds have become popular between unprofessional investors who don’t have sufficient knowledge. Research shows that financial institutions do not always provide the optimal proposals. Advanced software tools can help make better investment decisions. Commercial tools usually show potential profits of investment, but not always pay sufficient  attention to potential risks. This article analyzes both good and bad investment scenarios.

    Background: Clinical reasoning is generally defined as the numerous modes of thinking that guide clinical practice but little is known about the factors affecting how occupational therapists manage the decision-making process. The aim of this qualitative study was to explore the factors influencing the clinical reasoning of occupational therapists. Methods: Twelve occupational therapy practitioners working in mental and physical dysfunction fields participated in this study. The sampling method was purposeful and interviews were continued until data saturation. All the interviews were recorded and transcribed. The data were analyzed through a qualitative content analysis method. Results: There were three main themes. The first theme: socio-cultural conditions included three subthemes: 1- client beliefs; 2- therapist values and beliefs; 3- social attitude to disability. The second theme: individual attributions included two subthemes 1- client attributions; 2- therapist attributions. The final theme was the workplace environment with the three subthemes: 1- knowledge of the managers of rehabilitation services, 2- working in an inter-professional team; 3- limited clinical facilities and resources. Conclusion: In this study, the influence of the attitudes and beliefs of client, therapist and society about illness, abilities and disabilities upon reasoning was different to previous studies. Understanding these factors, especially the socio-cultural beliefs basis can play a significant role in the quality of occupational therapy services. Accurate understanding of these influential factors requires more extensive qualitative and quantitative studies. PMID:25250253

    Opening paragraph: Tidal and nontidal wetlands in the Chesapeake Bay watershed provide vital hydrologic, water-quality, and ecological functions. Situated at the interface of land and water, these valuable habitats are vulnerable to alteration and loss by human activities including direct conversion to non-wetland habitat by dredge-and-fill activities from land development, and to the effects of excessive nutrients, altered hydrology and runoff, contaminants, prescribed fire management, and invasive species. Processes such as sea-level rise and climate change also impact wetlands. Although local, State, and Federal regulations provide for protection of wetland resources, the conversion and loss of wetland habitats continue in the Bay watershed. Given the critical values of wetlands, the Chesapeake 2000 Agreement has a goal to achieve a net gain in wetlands by restoring 25,000 acres of tidal and nontidal wetlands by 2010. The USGS has synthesized findings on three topics: (1) sea-level rise and wetland loss, (2) wetland restoration, and (3) factors affecting wetland diversity.

    Full Text Available The purpose of this study was to characterize factors affecting lactose quantities in raw cow's milk. This study combined the survey design with laboratory analysis. Selected farm members of Nong Poh Dairy Cooperatives, from Ban Pong and Photharam Districts, Ratchaburi Province, were sampled. From the selected farms, data collected included lactose quantities in the raw milk and dairy farming information. The raw milk of selected farms was sampled at the delivery site of Nong Poh dairy cooperatives in the morning during December 2003 till February 2004. Lactose in the raw milk was then quantified by the Fourier Transform Infrared Analysis (FTIR using the MilkoScan FT6000 at the Department of Livestock Development. The farm owners or managers of selected farms were in-depth interviewed on dairy farming information including cowsí health and cows' diet. The data revealed that all cows from the selected farms were fed with concentrate diet purchased from Nong Poh Dairy Cooperatives and grass as high fiber diets. Sample of eighteen farms also fed their cows with one of supplements: corn stem, soybean meal, or rice straw. All cows from these farms were Holstein-Friesian Hybrid. As supplemented high fiber diets, corn stem significantly increased the lactose quantities over soybean meal and rice straw (planned comparison, pvalue = 0.044. The study concluded that some high fiber diets, specifically corn stem, significantly contributed to the lactose quantities in raw milk.

    Novozym 234 was the most frequently used enzyme for production of Rhizoctonia solani protoplasts. Since manufacture of this enzyme was discontinued in the late 1990s, a new procedure was developed by testing lytic enzymes from Sigma and by examining factors affecting protoplast formation. The combination of 20 mg/mL Driselase and 10mg/mL lysing enzyme was effective in releasing protoplasts from R. solani. The optimal condition for enzyme treatment of mycelium was incubation at 37 degrees C for 15 min followed by 34 degrees C for 105 min. The amount of protoplasts produced was positively correlated with growth rate and negatively correlated with mycelial density. Under favorable conditions, R. solani mycelia released 1.68 x 10(6) protoplasts/mL that is comparable with that produced with Novozym 234. Among various media tested, the best solid medium for protoplast regeneration was 1% V-8 juice agar, while the best liquid medium was 10% potato dextrose broth. Copyright 2009 Elsevier B.V.

    Full Text Available This paper explored the factors that affect career progress of students in the MBA program of the University of the Philippines.To understand career progression, four measures of career progress were used in this study, namely: number of promotions, number of years in between promotions, total cash compensation, and number of administrative levels from the company president. On the other hand, the factors used to explain career progess included human capital, organizational, interpersonal and demographic variables.The results showed that the different measures of career progress had distinct determinants implying different dynamics. It appeared that measures of career progress that are sensitive to the value employers attach to the individual (Whitely, Dougherty, & Dreher, 1991 such as total compensation, total number of promotion and years per promotion were related with human capital factors such as work experience and number of companies worked for. On the other hand, measures that relate to centrality if the position, in which market forces have less impact, were associated with organizational variables such as organization size and the demographic variable gender.While gender did not explain variation in total compensation, number of promotions and number of uears between promotions, these null results are important for two reasons. First, it implies that the female MBA students were at par with their male counterparts as fas as these measures of career progress are concerned. Second, it challenges the generalizability of the finding of gender segregation at the organizational level-where men receive significantly higher wages that women-which is a common finding among studies done in the United States. The results using the MBA students as sample show that income and promotion parity may indeed be achievable and this brings hope to women in general.However, the statistical significance of gender in explaining career progress as centrality

    Full Text Available Introduction Secondary sex ratio (SSR is the proportion of males to females at birth. It has been shown in many different mammalian species, many factors are associated with SSR. Changes in secondary sex ratio in dairy cows is considered economically important and the ability to change it could affect the revenues and profitability of a dairy farm. Thus, sperm or embryo sexing techniques in recent years has attracted more attention. Most breed of dairy cattle are more likely to have female calf is born to use them as replacement heifers and in order to maintain their productive herd number. On the contrary, when the goal is the production of meat, bull calves due to higher growth rates and production efficiency, are more convenient and more economically efficient. The aim of present study was to investigate some key factors affecting SSR in Iranian Holstein cows. According to Fisher, the sex ratio in the population under the control of natural selection is not always the same. There is overwhelming evidence to support the theory that shows Fisher Primary and secondary sex ratio sex ratio can deviate from this balance and natural selection caused a change in this ratio can be in certain circumstances. For example, the secondary sex ratio of 52:48 has been reported in dairy cows. Studies on mammalian species suggest that several factors, including latitude of the location, the dominant regional climate model, time and frequency of mating to ovulation, diet, age of parents, physical score, breed and produced eggs from ovarian left or right can have a significant effect on the secondary sex ratio. Weather conditions may modify the internal environment and the effect on physiological mechanisms or through the impact on the frequency and type of foods available to parents, the secondary sex ratio is impressive. The impact on the quantity and quality of parent's access to food sources in many species of mammals, the sex ratio has been fixed. Previous

    Cultures differ in the emotions they teach their members to value ("ideal affect"). We conducted 3 studies to examine whether leaders' smiles reflect these cultural differences in ideal affect. In Study 1, we compared the smiles of top-ranked American and Chinese government leaders, chief executive officers, and university presidents in their official photos. Consistent with findings that Americans value excitement and other high-arousal positive states more than Chinese, American top-ranked leaders (N = 98) showed more excited smiles than Chinese top-ranked leaders (N = 91) across occupations. In Study 2, we compared the smiles of winning versus losing political candidates and higher versus lower ranking chief executive officers and university presidents in the United States and Taiwan/China. American leaders (N = 223) showed more excited smiles than Taiwanese/Chinese leaders (N = 266), regardless of election outcome or ranking. In Study 3, we administered self-report measures of ideal affect in college student samples from 10 different nations (N = 1,267) and then 8 years later, coded the smiles that legislators from those nations showed in their official photos (N = 3,372). The more nations valued excitement and other high arousal positive states, the more their leaders showed excited smiles; similarly, the more nations valued calm and other low-arousal positive states, the more their leaders showed calm smiles. These results held after controlling for national differences in democratization, human development, and gross domestic product per capita. Together, these findings suggest that leaders' smiles reflect the affective states valued by their cultures.

    2010-01-01

    Adenovirus production is currently operated at low cell density because infection at high cell densities still results in reduced cell-specific productivity. To better understand nutrient limitation and inhibitory metabolites causing the reduction of specific yields at high cell densities, adenovirus production in HEK 293 cultures using NSFM 13 and CD 293 media were evaluated. For cultures using NSFM 13 medium, the cell-specific productivity decreased from 3,400 to 150 vp/cell (or 96% reduction) when the cell density at infection was increased from 1 to 3 x 10(6) cells/mL. In comparison, only 50% of reduction in the cell-specific productivity was observed under the same conditions for cultures using CD 293 medium. The effect of medium osmolality was found critical on viral production. Media were adjusted to an optimal osmolality of 290 mOsm/kg to facilitate comparison. Amino acids were not critical limiting factors. Potential limiting nutrients including vitamins, energy metabolites, bases and nucleotides, or inhibitory metabolites (lactate and ammonia) were supplemented to infected cultures to further investigate their effect on the adenovirus production. Accumulation of lactate and ammonia in a culture infected at 3 x 10(6) cells/mL contributed to about 20% reduction of the adenovirus production yield, whereas nutrient limitation appeared primarily responsible for the decline in the viral production when NSFM 13 medium was used. Overall, the results indicate that multiple factors contribute to limiting the specific production yield at cell densities beyond 1 x 10(6) cells/mL and underline the need to further investigate and develop media for better adenoviral vector productions.

    Abstract Pelvic rotation (PR) is commonly seen in patients with idiopathic scoliosis (IS), but factors contributing to this phenomenon and its relationship with the surgical outcome are not well established. This retrospective study included 85 IS patients in 2 groups: thoracic curve dominance group (group A) and lumbar curve dominance group (group B). Pre- and postoperative PR was measured on standing posteroanterior radiographs by the left/right ratio (L/R ratio) of horizontal distance between the anterior superior iliac spine (ASIS) and the inferior ilium (SI) at the sacroiliac joint on the same side in both groups. Other radiographic data, age, sex, and Risser sign of each patient were recorded to analyze their correlations with PR before and after operation. The patients ranged in age from 10 to 35 years with a mean of 17.0 ± 5.2 years. The mean L/R ratio of PR before operation was 0.99 (0.73–1.40) versus 0.98 (0.87–1.26) after operation. The L/R ration was beyond the range of 1 ± 0.1 (indicating the presence of PR) in 17 (20%) patients before operation and in 14 (16.5%) patients after operation. There was no significant difference in PR between the 2 groups of patients either before (P = 0.468) or after (P = 0.944) surgery. The preoperative PR showed a very low correlation with Risser sign (r = 0.220, P = 0.043), apex vertebral rotation (AVR) in the proximal thoracic curve (r = 0.242, P = 0.026), and AVR in the lumbar curve (r = 0.213, P = 0.049), while the postoperative PR showed a very low correlation with Risser sign (r = −0.341, P = 0.001) and postoperative trunk shift (TS) (r = −0.282, P = 0.009). Multiple stepwise regression analysis showed that preoperative PR was affected by proximal thoracic curve AVR and lumbar curve AVR. There was no significant difference between PR before operation and 2 years after operation. Preoperative PR was mainly correlated with Risser sign and the rotation

  13. Has solar variability caused climate change that affected human culture?

    Science.gov (United States)

    Feynman, Joan

    If solar variability affects human culture it most likely does so by changing the climate in which the culture operates. Variations in the solar radiative input to the Earth's atmosphere have often been suggested as a cause of such climate change on time scales from decades to tens of millennia. In the last 20 years there has been enormous progress in our knowledge of the many fields of research that impinge on this problem; the history of the solar output, the effect of solar variability on the Earth's mean climate and its regional patterns, the history of the Earth's climate and the history of mankind and human culture. This new knowledge encourages revisiting the question asked in the title of this talk. Several important historical events have been reliably related to climate change including the Little Ice Age in northern Europe and the collapse of the Classical Mayan civilization in the 9th century AD. In the first section of this paper we discus these historical events and review the evidence that they were caused by changes in the solar output. Perhaps the most important event in the history of mankind was the development of agricultural societies. This began to occur almost 12,000 years ago when the climate changed from the Pleistocene to the modern climate of the Holocene. In the second section of the paper we will discuss the suggestion ( Feynman and Ruzmaikin, 2007) that climate variability was the reason agriculture developed when it did and not before.

  15. An Analysis on the Contextual Factors Affecting Motivation in SLA

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    <正>For us Chinese,a foreign language is something to be acquired as a kind of communicative tool,so we can infer that an effective way in SLA(Second Language Acquisition) must be learning the target language in a communicative context.A communicative context certainly concerns not only the interactional classroom activities designed in accordance with some stated curriculum tasks to lead the L2 students to learning swimming by swimming,but also other relevant elements which have a lot to do with all the situational,interactional and cultural contexts.In order to lessen some potential sources of conflict between L2 teacher and L2 learner,this article is an attempt to urge a careful study on the contextual factors affecting motivation in SLA.

    Tests of famous faces are used to study language and memory. Yet, the effect of stimulus properties on performance has not been fully investigated. To identify factors influencing proper name retrieval and to probe stimulus-specific parameters within proper name lexicon, we analysed the results obtained by 300 healthy participants on a test of famous faces that includes 74 personalities. A factor analysis yielded five main factors that were characterized by language (national or foreign names), epoch of peak popularity (current, recent or past) and occupation (politicians, entertainment and sports) of the personalities. Multiple regression analysis showed that participants' education, age and gender accounted for 10-32% of the variance in factor scores. These results indicate that there are variables of the stimulus and participants' that must be taken into account in proper name testing and in designing tests aimed to differentiate age-associated difficulties from cognitive decline.

    Disease screening instruments used for secondary prevention can facilitate early determination and treatment of pathogenic factors, effectively reducing disease incidence, mortality rates, and health complications. Therefore, people should be encouraged to receive health examinations for discovering potential pathogenic factors before symptoms occur. Here, we used the health belief model as a foundation and integrated social psychological factors and investigated the factors influencing health examination behavioral intention among the public in Taiwan. In total, 388 effective questionnaires were analyzed through structural model analysis. Consequently, this study yielded four crucial findings: (1) The established extended health belief model could effectively predict health examination behavioral intention; (2) Self-efficacy was the factor that most strongly influenced health examination behavioral intention, followed by health knowledge; (3) Self-efficacy substantially influenced perceived benefits and perceived barriers; (4) Health knowledge and social support indirectly influenced health examination behavioral intention. The preceding results can effectively increase the acceptance and use of health examination services among the public, thereby facilitating early diagnosis and treatment and ultimately reducing disease and mortality rates.

    2016-08-01

    Full Text Available Biogenic amines (BAs are molecules which can be present in foods and, due to their toxicity, can cause adverse effects on the consumers. BAs are generally produced by microbial decarboxylation of amino acids in food products. The most significant BAs occurring in foods are histamine, tyramine, putrescine, cadaverine, tryptamine, 2-phenylethylamine, spermine, spermidine and agmatine. The importance of preventing the excessive accumulation of BAs in food is related to their impact on human health and food quality. Quality criteria in connection with the presence of BAs in food and food products are necessary from a toxicological point of view. This is particularly important in fermented foods in which the massive microbial proliferation required for obtaining specific products is often relater with BA accumulation. In this review, up-to-date information and recent discoveries about technological factors affecting biogenic amine content in foods are reviewed. Specifically, BA forming-microorganism and decarboxylation activity, genetic and metabolic organization of decarboxylases, risk associated to BAs (histamine, tyramine toxicity and other BAs, environmental factors influencing BA formation (temperature, salt concentration, pH. In addition, the technological factors for controlling BA production (use of starter culture, technological additives, effects of packaging, other non-thermal treatments, metabolising BA by microorganisms, effects of pressure treatments on BA formation and antimicrobial substances are addressed.

    Full Text Available Levodopa is the gold standard for the treatment of Parkinson's disease (PD because of its outstanding clinical efficacy. However, the majority of patients experience various adverse reactions, including the wearing-off phenomenon, the on-off phenomenon, dyskinesia and psychiatric symptoms. The response to levodopa depends not only on the intrinsic responsiveness of the patients, but also on various other important factors including the type of levodopa preparation, its absorption/metabolism, the blood-brain barrier, age at onset of disease and concomitant use of anti-parkinsonian drugs. This review summarizes factors which influence the effects of levodopa in PD. To minimize levodopa-induced adverse reactions and to relieve long-term parkinsonian symptoms, levodopa therapy should be conducted by taking these factors into consideration.

Bacteriol. 87:504–509. 1964.—Tests were carried out to determine the optimal culture conditions for the production of cobamide coenzymes in Clostridium tetanomorphum strain H1. A method is described for carrying out coenzyme determinations on the cells from 10-ml cultures of the bacterium. In a basal medium containing magnesium sulfate, ferrous sulfate, manganese sulfate, sodium molybdate, calcium chloride, and potassium phosphate, the optimal concentration of monosodium glutamate was 0.1 m and of yeast extract was 3 g per liter. Addition of glucose at a concentration of 0.05 m was found to double the yield of cells and to increase tenfold the specific coenzyme yield. Addition of cobaltous chloride (2 × 10−5m) also increased coenzyme production. Addition of benzimidazole caused an apparent increase in coenzyme production by causing the synthesis of the highly active benzimidazole analogue. Addition of methionine (5 × 10−6m) appeared to inhibit coenzyme production. PMID:14127565

    Primary neurons in culture from chick embryo cerebral hemispheres were treated with a mixture of gangliosides added to the growth medium (final concentration: 10(-5)M and 10(-8)M) from the 3rd to the 6th day in vitro. Under these conditions methylation processes measured with (3H) and (35S) methionine and (3H)ethanolamine as precursors showed an increased methylation of (3H)ethanolamine containing phospholipids, a correspondent increased conversion of these compounds to (3H)choline containing phospholipids, and a general increased methylation of trichloroacetic acid precipitable macromolecules containing labeled methionine. A small increase in protein synthesis was observed after incubation of neurons with (3H)- and (35S)methionine. This was confirmed after electrophoretic separation of a protein extract with increased 3H- and 35S-labeling in protein bands with moecular weights between 50 and 60 KDaltons. A protein band of about 55 KDaltons appeared to be preferentially labelled when (3H) methionine was the precursor. The treatment with gangliosides increased the incorporation of (methyl-3H) label after incubation of neurons with (3H) methionine, into total DNA and decreased that of total RNA. The treatment of neurons in culture with exogenous gangliosides hence affects differently methylation processes, a finding which may confirm the involvement of gangliosides on the intracellular mediation of neuronal information mechanisms.

    Language is the carrier of culture, and translation is a cultural information exchanging process in which the connotation of one language is expressed in the other one, namely, translation is not only the process of language exchanging but also the process of culture exchanging. To a great extent, the transform of culture information is restricted by culture factors. Therefore, in order to reappear the original flavor naturally and properly during the process of translation, one must think highly of the fact that culture factors affect translation activities a lot. This thesis transilluminates the culture factors in E/C translation through the translation comparison among the Chinese and English set phrases, idioms, allusions, sayings, and colloquialism; It also tries to analyze the way of cultural information transaction in E/C translation and put forward the opinion to it.

    Culturing embryos in groups is a common practice in mammalian embryology. Since the introduction of different microwell dishes, it is possible to identify oocytes or embryos individually. As embryo density (embryo-to-volume ratio) may affect the development and viability of the embryos, the purpose of this study was to assess the effect of different embryo densities on embryo quality. Data of 1337 embryos from 228 in vitro fertilization treatment cycles were retrospectively analyzed. Embryos were cultured in a 25 μl microdrop in a microwell group culture dish containing 9 microwells. Three density groups were defined: Group 1 with 2-4 (6.3-12.5 μl/embryo), Group 2 with 5-6 (4.2-5.0 μl/embryo), and Group 3 with 7-9 (2.8-3.6 μl/embryo) embryos. Proportion of good quality embryos was higher in Group 2 on both days (D2: 18.9 vs. 31.5 vs. 24.7%; p Culturing 5-6 embryos together in a culture volume of 25 μl may benefit embryo quality. As low egg number, position, and distance of the embryos may influence embryo quality, results should be interpreted with caution.

    Full Text Available The article is devoted to the analysis of socio-demographic and individual psychological characteristics that influence the verdict of jury. The study involved 38 men and women aged 25 to 64 years. With the help of a questionnaire, developed on the basis of legal development model by J. Tapp and F. Levine, we revealed levels of jury members’ legal conscience, which, together with socio-demographic characteristics and personality characteristics of the subjects, identified by R. Cattell 16PF Questionnaire, were related to the responses on the Questionnaire while returning verdict on specially selected criminal cases with implicit guilt of the defendant. According to the study, it was determined that the socio-demographic characteristics of the jurors did not significantly affect their verdict, and among the psychological characteristics of the jurors the greatest impact on their verdict has the level of legal development. Thus, depending on the nature of the crime (violent, non-violent or committed through negligence, the same level of legal conscience differently affect the decision of jurors.

  4. Circulation factors affecting precipitation over Bulgaria

    Nojarov, Peter

    2017-01-01

    The objective of this paper is to determine the influence of circulation factors on precipitation in Bulgaria. The study succeeds investigation on the influence of circulation factors on air temperatures in Bulgaria, as the focus here is directed toward precipitation amounts. Circulation factors are represented through two circulation indices, showing west-east or south-north transport of air masses over Bulgaria and four teleconnection indices (patterns)—North Atlantic Oscillation, East Atlantic, East Atlantic/Western Russia, and Scandinavian. Omega values at 700-hPa level show vertical motions in the atmosphere. Annual precipitation trends are mixed and not statistically significant. A significant decrease of precipitation in Bulgaria is observed in November due to the strengthening of the eastward transport of air masses (strengthening of EA teleconnection pattern) and anticyclonal weather (increase of descending motions in the atmosphere). There is also a precipitation decrease in May and June due to the growing influence of the Azores High. An increase of precipitation happens in September. All this leads to a redistribution of annual precipitation course, but annual precipitation amounts remain the same. However, this redistribution has a negative impact on agriculture and winter ski tourism. Zonal circulation has a larger influence on precipitation in Bulgaria compared to meridional. Eastward transport throughout the year leads to lower than the normal precipitation, and vice versa. With regard to the four teleconnection patterns, winter precipitation in Bulgaria is determined mainly by EA/WR teleconnection pattern, spring and autumn by EA teleconnection pattern, and summer by SCAND teleconnection pattern.

    White, Mary Joe; Olson, Rhonda S

    2004-01-01

    A discouraging trend in many specialty nursing organizations is the stagnant or declining membership. The research committee of the Southeast Texas Chapter of the Association of Rehabilitation Nurses (ARN) collected data and studied this trend to determine what changes would be necessary to increase membership. Using Herzberg's motivational theory as a framework, a review of the literature was initiated. There were few current studies on this issue, but relevant information was found about nursing's emerging workforce, as well as implications of the growth of magnet hospitals, which affect whether nurses join specialty nursing organizations. A multifaceted data-collection approach using convenience samples was designed. First, relevant literature was reviewed. Second, a survey was sent by e-mail to other ARN chapters. Third, a telephone survey on other specialty organizations in the geographic region was completed. Finally, members of the local ARN chapter and four other specialty organizations, as well staff nurses in the geographic area, were given questionnaires to complete. Descriptive statistics and cross tabulations were used to determine why nurses do and do not join specialty organizations (N = 81). The most frequent reasons for joining an organization were to increase knowledge, benefit professionally, network, and earn continuing education units. Reasons for choosing not to participate were family responsibilities, lack of information about these organizations, and lack of time. Ways to reverse the decline in membership are discussed.

    1976-06-01

    Certain habitat and social factors were investigated for their effect on home range size of mallard (Anas platyhynchos) pairs breeding in a forested region of north-central Minnesota during the spring of 1971--72. Data from 31 radio-marked hens and drakes were used, but primary emphasis was placed on 8 pairs (5 with both members of the pair marked). Pairs were radio-tracked on river marsh areas, river channels, and large sand lakes to provide comparative data for evaluating home range size differences. Home ranges varied from an average of 53 ha for pairs using primarily river habitat to 871 ha for pairs using only large sand lakes. River and lake shorelines varied considerably in species and density of vegetation. Interaction between pairs as well as density of flocked males appeared to be influenced by these habitat differences with resultant effects on home range sizes.

    Objective. This research was guided by a stress and support model to examine the effects of frontline workers' background characteristics, personal stressors, job-related stressors, and workplace support on satisfaction with supervision. Method. Survey data were collected from 644 workers in 49 long-term-care settings that employed them. Regression analysis were used to determine the effects of worker level and then Hierarchical Linear Modeling (HLM) and organizational factors on the outcome. Results. Although all four variable categories made significant contributions to explaining satisfaction with supervision, the most powerful were personal stressors and job-related stressors. Results from HLM analysis showed frontline workers in nursing homes and those employed in for-profit organizations had lower levels of satisfaction with supervision. Discussion. Findings suggest organizational interventions to address workers' financial and health issues and management practices such as better training programs and peer mentoring could enhance workers' satisfaction with supervision.

    2015-10-01

    Chloroquine is an antimalarial drug but is also prescribed for conditions such as rheumatoid arthritis. Long-term users risk toxic side effects, including retinopathy, thought to be caused by chloroquine accumulation on ocular melanin. Although the binding potential of chloroquine to melanin has been investigated previously, our study is the first to demonstrate clear links between chloroquine adsorption by melanin and system factors including temperature, pH, melanin type, and particle size. In the current work, two Sepia melanins were compared with bovine eye as a representative mammalian melanin. Increasing the surface anionic character due to a pH change from 4.7 to 7.4 increased each melanin's affinity for chloroquine. Although the chloroquine isotherms exhibited an apparently strong interaction with each melanin, isosteric heat analysis indicated a competitive interaction. Buffer solution cations competed effectively at low surface coverage; chloroquine adsorption occurs via buffer cation displacement and is promoted by temperature-influenced secondary structure swelling.

    Chinese dietary reference intakes (DRIs) for calcium were developed mainly from studies conducted amongst Caucasians, yet a recent review showed that reference calcium intakes for Asians are likely to be different from those of Caucasians (Lee and Jiang, 2008). In order to develop calcium DRIs for Chinese adolescents, it is necessary to explore the characteristics and potential influencing factors of calcium metabolic balance in Chinese adolescents. A total of 80 students (15.1+/-0.8 years) were recruited stratified by gender from a 1-year calcium supplementation study. Subjects were randomly designed to four groups and supplemented with calcium carbonate tablets providing elemental calcium at 63, 354, 660, and 966 mg/day, respectively. Subjects consumed food from a 3-day cycle menu prepared by staff for 10 days. Elemental calcium in samples of foods, feces, and urine was determined in duplicates by inductively coupled plasma atomic emission spectrometry. The total calcium intake ranged from 352 to 1323 mg/day. The calcium apparent absorption efficiency and retention in boys were significantly higher than that in girls (68.7% vs. 46.4%, 480 mg/day vs. 204 mg/day, PCalcium retention increased with calcium intakes, but did not reach a plateau. Calcium absorption efficiency in boys increased with calcium intake up to 665 mg/day, and decreased after that. In girls, calcium absorption efficiency decreased with calcium intake. Calcium absorption efficiency increased within 1 year after first spermatorrhea in boys, but decreased with pubertal development in girls. Sex, calcium intake, age, and pubertal development were the most important determinants of calcium absorption (R(2)=0.508, Pcalcium intake, age, and pubertal development are important factors for calcium retention and absorption during growth, which should be considered for the development of calcium DRIs for Chinese adolescents.

    Full Text Available In response to a shift toward specialization and mechanization during the 20th century, there has been momentum on the part of a vocal contingent of consumers, producers, researchers, and policy makers who call for a transition toward a new model of agriculture. This model employs fewer synthetic inputs, incorporates practices which enhance biodiversity and environmental services at local, regional, and global scales, and takes into account the social implications of production practices, market dynamics, and product mixes. Within this vision, diversified farming systems (DFS have emerged as a model that incorporates functional biodiversity at multiple temporal and spatial scales to maintain ecosystem services critical to agricultural production. Our aim is to provide an economists' perspective on the factors which make diversified farming systems (DFS economically attractive, or not-so-attractive, to farmers, and to discuss the potential for and roadblocks to widespread adoption. We focus on how a range of existing and emerging factors drive profitability and adoption of DFS. We believe that, in order for DFS to thrive, a number of structural changes are needed. These include: 1 public and private investment in the development of low-cost, practical technologies that reduce the costs of production in DFS, 2 support for and coordination of evolving markets for ecosystem services and products from DFS and 3 the elimination of subsidies and crop insurance programs that perpetuate the unsustainable production of staple crops. We suggest that subsidies and funding be directed, instead, toward points 1 and 2, as well as toward incentives for consumption of nutritious food.

    Full Text Available Introduction: Alcohol is one of the major risk factors for individuals’ and society’s health. Alcohol consumption is present since ancient years in Europe, constituting tradition, with Europeans preferring different kinds of alcohol depending on the geographic location of their country. The economic crisis that European citizens are undergoing nowadays, has an impact on their health and more specifically there has been a significant increase in alcohol consumption. Material and Methods: The purpose of this study is to explore the factors which effect the alcohol consumption and consequences of this consumption in Europe. Literature review of relevant articles, published from 2005 to 2013, to these databases: WHO, Google scholar, PubMed. Finally, 42 studies were used to our review. Results: The alcohol consumption is connected with the economic situation of the country, the availability of alcohol, the restrictions and taxes of each country. Alcohol consumption is also related with the gender and age of each individual. In Central-eastern Europe, in contrast to the south Europe, the greatest percentage of mortality caused by the alcohol consumption is found. 35,95% is the mortality rate which is found in Europe. Regarding Greece in recent years, alcohol consumption has declined, while the rates of intoxication have shown as light increase. Conclusions: The lack of legislation, the non-existence of a minimum sale price and the increased availability, can lead to increased incidence of mortality caused by the alcohol consumption. Further research regarding the correlation of economic crisis and alcohol consumption is necessary.

  17. Ostracism and attachment orientation: Avoidants are less affected in both individualistic and collectivistic cultures.

    Yaakobi, Erez; Williams, Kipling D

    2016-03-01

    Ostracism--being excluded and ignored--is painful and threatens needs for belonging, self-esteem, control and meaningful existence. Many studies have shown that immediate responses to ostracism tend to be resistant to moderation. Once ostracized individuals are able to reflect on the experience, however, personality and situational factors moderate recovery speed and behavioural responses. Because attachment orientation is grounded in perceptions of belonging, we hypothesized that attachment orientation would moderate both immediate and delayed reactions to laboratory-induced ostracism. Participants from individualistic or collectivistic cultures were either included or ostracized in a game of Cyberball, a virtual ball-toss game. In both cultures, we found that compared to more securely attached individuals, more avoidant participants were less distressed by ostracism, but more distressed by inclusion. It is suggested that over and beyond differences in culture, individuals who avoid meaningful attachment may be less affected by ostracism.

    Full Text Available Hypertension is a common chronic disease in the elderly. This study aimed to determine the effects of age, ethnicity, gender, education, marital status, nutritional parameters, and blood elements on the risk of high blood pressure in the Malaysian elderly. This research was conducted on a group of 2322 non-institutionalized Malaysian elderly. The hierarchy binary logistic regression analysis was applied to estimate the risk of hypertension in respondents. Approximately, 45.61% of subjects had hypertension. The findings indicated that the female gender (Odds ratio (OR = 1.54, an increase in body weight (OR = 1.61, and an increase in the blood levels of albumin (OR = 1.51, glucose (OR = 1.92, and triglycerides (OR = 1.27 significantly increased the risk of hypertension in subjects (p < 0.05. Conversely, an increase in both dietary carbohydrates (OR = 0.74, and blood cholesterol level (OR = 0.42 significantly reduced the risk of hypertension in samples (p < 0.05. Furthermore, the results showed that ethnicity was a non-relevant factor to increase the risk of hypertension in subjects. It was concluded that female gender, an increase in body weight, and an increase in the blood levels of glucose, triglycerides, and albumin enhanced the risk of high blood pressure in the Malaysian elderly. In addition, an increase in both dietary carbohydrates and blood cholesterol level decreased hypertension in subjects.

    Full Text Available Objective: The increase in life quality and expectancy causes an increase in the elderly population. Improvements in burn treatment resulted in decreased mortality in children and young adults but in elderly patients burns are still an important trauma that should be handed differently than other age groups. The aim of this study was to evaluate the factors effecting mortality in patients with burns over 45 years old. Methods: Fifty-eight patients over 45 years of age, who were treated in our burns unit in the last 3 years were included in our study. Their age, burn percentage and depth, coexisting diseases and mortality rates were examined retrospectively. Results: The average age of surviving patients was 57.4 years while it was 70 years for nonsurviving patients (p=0.002. The width of burn area was 21.1 % in surviving and 50 % in nonsurviving patients (p<0.01. The effect of additional coexistent diseases on mortality was significant (p=0.001. The most common reasons of mortality were sepsis and congestive heart failure. Conclusion: We found out that the age, percentage of burns and coexistent diseases had a negative effect on success of treatment and mortality. Mortality rates will decrease in these cases with careful follow-up and a multidisciplinary approach. J Clin Exp Invest 2015; 6 (3: 240-243

    2015-01-01

    Captive bolt stunning is used for rendering livestock insensible at slaughter. The mechanical factors relating to performance of 6 penetrating captive bolt gun (CBG) models were examined. The Matador Super Sécurit 3000 and the .25 Cash Euro Stunner had the highest kinetic energy values (443 J and 412 J, respectively) of the CBGs tested. Ninety percent (27/30) of CBGs held at a government gun repository (United Kingdom) were found to have performed at a normal standard for the model, while 53% (10/19) of commercial contractor CBGs tested were found to underperform for the gun model. When the .22 Cash Special was fired 500 times at 4 shots per min, the gun reached a peak temperature of 88.8°C after 2.05 hr. Repeat firing during extended periods significantly reduced the performance of the CBG. When deciding on the appropriate CBG/cartridge combination, the kinetic energy delivered to the head of the nonhuman animal, bolt penetration depth, and species/animal type must be considered. It is recommended that CBGs are routinely checked for wear to the bolt and barrel if they are repeatedly fired in a session.

    Tseng, Juliana; Halperin, Lucila; Ritholz, Marilyn D; Hsu, William C

    2013-01-01

    Diabetes has become a global pandemic and Chinese Americans are at least 60% more likely to develop type 2 diabetes than White Americans, despite having lower body weight, due to a combination of genetic and environmental factors. Because of the increased risk, it is vitally important to address the issues of treatment adherence and diabetes self-management in the Chinese American population. Many factors affect an individual's ability to manage diabetes, including cultural beliefs, immigration experience, language abilities/health literacy, educational background, employment, and accessibility of healthcare services. In treating Chinese American patients, these factors must be considered to determine appropriate treatment. Eastern cultural and individual beliefs differ greatly from Western beliefs and, therefore, may affect the presentation of the patients. If left unacknowledged, these differences might be misinterpreted by healthcare providers as merely treatment non-adherence or unwillingness to change. Suggestions for providing culturally competent healthcare are discussed. Copyright © 2013 Elsevier Inc. All rights reserved.

    2015-12-01

    Taiwan is a multicultural and multiethnic society with a growing number of immigrants who have diverse ethnic, racial, and cultural needs. Although this diversity highlights the pressing need for culturally competent healthcare providers, cultural competence is a concept that is little understood and implemented only sporadically in Taiwan. This study investigates the cultural competence of Taiwanese nurses and the related factors of influence. An online self-report survey was used to collect data from 221 Taiwanese nurses from December 2012 through January 2013. Data from the demographic questionnaire, the Nurses' Cultural Competence Scale, and the Perceived Nurses' Cultural Competence Rating were analyzed using descriptive statistics, Pearson correlation, independent sample t tests, and multiple regressions. The cultural competence of the participants was in the "low to moderate" range, with relatively higher mean scores for the subscales of cultural awareness and cultural sensitivity and relatively lower scores for the subscales of cultural knowledge and cultural skills. Participants generally perceived themselves as being "not culturally competent." Variables found to predict cultural competence included years of work experience, hours of continuing education related to cultural nursing care, and frequency of caring for clients from culturally and ethnically diverse backgrounds. Participating Taiwanese nurses rated their level of cultural competence as in the low-to-moderate range and self-perceived as being not culturally competent. These findings support the need to further expand and enhance cultural-competence-related continuing education and to address the topic of cultural care in the nursing curricula.

    In the heavy oil industry, thermal processes are used to enhance oil recovery by increasing the reservoir temperature which results in better oil mobility. Low frequency heating (LFH) is a technology using electrical conductivity of connate water to propagate current between electrodes, thus generating heat in the reservoir through the Joule effect. During the preheating and production periods, many physical factors may affect the LFH process and the aim of this study was to determine which factors affect the process and how, using a particular pattern of electrodes. Simulations were conducted using the CMG Stars reservoir simulator under different configurations, conditions and parameters. Important physical properties and operational conditions affecting the LFH process were determined and results showed that convection heat, bulk electrical conductivity and power distribution can be improved by salt water circulation. This paper highlighted the physical factors affecting LFH efficiency and these findings will be useful for future process design.

    The growing use of internet and online purchasing among young consumers in Malaysia provides a huge prospect in e-commerce market, specifically for B2C segment. In this market, if E-marketers know the web-based factors affecting online buyers' behaviour, and the effect of these factors on behaviour of online consumers, then they can develop their marketing strategies to convert potential customers into active one, while retaining existing online customers. Review of previous studies related to the online purchasing behaviour in B2C market has point out that the conceptualization and empirical validation of the online purchasing behaviour of Information and Communication Technology (ICT) literate users, or ICT professional, in Malaysia has not been clearly addressed. This paper focuses on (i) web-based factors which online buyers (ICT professional) keep in mind while shopping online; and (ii) the effect of web-based factors on online purchasing behaviour. Based on the extensive literature review, a conceptual framework of 24 items of five factors was constructed to determine web-based factors affecting online purchasing behaviour of ICT professional. Analysis of data was performed based on the 310 questionnaires, which were collected using a stratified random sampling method, from ICT undergraduate students in a public university in Malaysia. The Exploratory factor analysis performed showed that five factors affecting online purchase behaviour are Information Quality, Fulfilment/Reliability/Customer Service, Website Design, Quick and Details, and Privacy/Security. The result of Multiple Regression Analysis indicated that Information Quality, Quick and Details, and Privacy/Security affect positively online purchase behaviour. The results provide a usable model for measuring web-based factors affecting buyers' online purchase behaviour in B2C market, as well as for online shopping companies to focus on the factors that will increase customers' online purchase.

    Full Text Available Facioscapulohumeral muscular dystrophy (FSHD is believed to be caused by aberrant expression of double homeobox 4 (DUX4 due to epigenetic changes of the D4Z4 region at chromosome 4q35. Detecting DUX4 is challenging due to its stochastic expression pattern and low transcription level. In this study, we examined different cDNA synthesis strategies and the sensitivity for DUX4 detection. In addition, we investigated the effects of dexamethasone and knockout serum replacement (KOSR on DUX4 expression in culture. Our data showed that DUX4 was consistently detected in cDNA samples synthesized using Superscript III. The sensitivity of DUX4 detection was higher in the samples synthesized using oligo(dT primers compared to random hexamers. Adding dexamethasone to the culture media significantly suppressed DUX4 expression in immortalized (1.3 fold, p < 0.01 and primary (4.7 fold, p < 0.01 FSHD myoblasts, respectively. Culture medium with KOSR increased DUX4 expression and the response is concentration dependent. The findings suggest that detection strategies and culture conditions should be carefully considered when studying DUX4 in cultured cells.

    Full Text Available Purpose: The purpose of the paper is to identify the factors that affect the development of the models of financial market state supervision and to identify the factors that have influenced the evolution of the supervision model in Poland. Methodology: critical analysis of literature, legal provisions and documents. Findings: The completely integrated and the fully dispersed model of supervision are located at the opposite ends of the spectrum. A variety of the hybrid models can be identified between them. Factors that affect supervision organization are both economic and non-economic. Factors that have influenced the Polish model of supervision include political aspects, administration costs and, in due course, also the development of the financial market. Research implications: The variety of state supervision structures, combined with the ambiguity and multiplicity of factors that affect their evolution create a new research challenge. Significant problems in accessing documents have been identified. Originality: The author presents an overview of models of state supervision of financial markets and factors affecting the evolution and structure of supervision. Conclusions drawn from the analysis were used to identify factors that influence the evolution and supervision of the Polish financial market.

    Full Text Available The paper tries to establish the correlation that exists between the types of organizational culture and the factors that influence knowledge transfer. We started from the hypothesis that organizations which have high scores for cultural factors of openness to change and innovation as well as for task-oriented organizational growth will have the tendency of being favourable to knowledge transfer. Moreover, we started from the hypothesis that organizations that have high scores for bureaucracy and competition factors will have the tendency of being unfavourable to knowledge transfer. The research reached the conclusion that there seems to be a correlation between organizational culture and the factors that influence knowledge transfer.

  20. Diverse decisions. How culture affects ethical decision making.

    Wright, F; Cohen, S; Caroselli, C

    1997-03-01

    Even under optimal conditions, assisting patients and families in making ethical decisions is difficult at best. Often these decisions revolve around the end-of-life issues that require acknowledgement that the patient is unlikely to survive, which may be perceived as a failure to both the family and the staff. At the very least, it can be a sad time, fraught with uncertainty and indecision. When these difficulties are coupled with ineffective communication related to cultural insensitivity or unawareness, the effects can be devastating to the decision-making process. All CCNs are expected to master the skills necessary for assisting patients and families through the harrowing experience of life-threatening illness. Whereas much of critical care focuses on managing pathophysiologic disturbances, emotional needs are equally important. It follows then that the CCN must assume responsibility for assisting patients and families in coping with the crisis of critical illness and working through ethical issues, which often include end-of-life decisions and organ donation. Culturally competent care is required when addressing patient needs holistically, but it is so much more. It is an opportunity to enrich and deepen the CCN/patient/family relationship, advocate for the patient, and broaden the opportunities for communication among staff. This article has provided some beginning steps for increasing nursing cultural awareness and has offered some initial strategies to consider when designing a plan of care. Through continuing efforts, CCNs and organizations can do much to decrease the alienation that many patients and families have traditionally encountered in the CCU, an estrangement that is exacerbated when their culture is different from the predominant culture of the unit. The effort to become more culturally aware may appear to require extraordinary effort; however, the rewards of optimizing patient care are unsurpassed.

    The factors affecting the acceptance of mobile obesity-management applications (apps) by the public were analyzed using a mobile healthcare system (MHS) technology acceptance model (TAM). The subjects who participated in this study were Android smartphone users who had an intent to manage their weight. They used the obesity-management app for two weeks, and then completed an 18-item survey designed to determine the factors influencing the acceptance of the app. Three questions were asked pertaining to each of the following six factors: compatibility, self-efficacy, technical support and training, perceived usefulness, perceived ease of use, and behavior regarding intention to use. Cronbach's alpha was used to assess the reliability of the scales. Pathway analysis was also performed to evaluate the MHS acceptance model. A total of 94 subjects participated in this study. The results indicate that compatibility, perceived usefulness, and perceived ease of use significantly affected the behavioral intention to use the mobile obesity-management app. Technical support and training also significantly affected the perceived ease of use; however, the hypotheses that self-efficacy affects perceived usefulness and perceived ease of use were not supported in this study. This is the first attempt to analyze the factors influencing mobile obesity-management app acceptance using a TAM. Further studies should cover not only obesity but also other chronic diseases and should analyze the factors affecting the acceptance of apps among healthcare consumers in general.

    Insight into factors that affect students' choice of university is useful when designing study programmes, especially in global competition for students. This study focuses on Taiwanese and Norwegian students' preferences for university, study programme, course qualities and future career qualities. Hofstede's model was used to predict culture-related differences. A pair-wise decision questionnaire was used to conduct measurements. Cultural differences were observed in relation to choice of university, course qualities and future careers. Discipline of study had only minor impact on students' preferences. The results suggest that a career-relevant curriculum is culture-neutral. Moreover, personal advice is the most preferred factor among Taiwanese students when choosing university.

  15. Hooked on an Affect: Detroit Techno and Dystopian Digital Culture

    Directory of Open Access Journals (Sweden)

    Richard Pope

    2011-03-01

    Full Text Available Detroit techno is typically historicized as having grown out of the late 1970s and early 1980s middle-class, consumerist, and aspirational high school social party scene, giving the impression that Detroit techno artists created forward-thinking music as a means to acquire subcultural capital and (reproduce their identities. In this essay, this position is nuanced for a more complex understanding of techno’s relation to the quotidian phenomenological encounter with the dystopian setting of Detroit. Concomitantly, predominant theorizations of affect within the humanities, which emphasize the utopian, hopeful dimensions of affect’s inherent productivity, are supplemented for an understanding of productive energy revolving around affects of dystopia and on a certain hopelessness which scholars, in the years ahead, will increasingly have to negotiate.Keywords: techno, Detroit, dystopia, affect, aesthetic, desire, subculture

    Educational environment has an important effect on the quality of learning and student satisfaction in medicine. Most of previous studies have been conducted using questionnaires that assess the phenomenon considering overall dimensions, without paying attention to the specific manifestations of this topic, especially those aspects that are related to the protagonists of the learning process: teachers and students. To describe factors that affect the educational environment in the preclinical Medical formation, according to Medical teachers in Concepción, Chile. Qualitative study, using the Grounded theory method. Semi-structured interviews were performed to 10 medical teachers in Concepcion, Chile. They were selected by theoretical sampling. Data were analyzed using open coding. Four emerging categories about the factors that affect the learning environment were identified: Personal factors of students, academic factors of students, personal factors of teachers and academic factors of teachers. According to interviewed teachers, both personal factors in teachers and students that promote a positive learning environment are related with an attitude oriented towards others and communication skills. Academic factors are related with the responsible exercise of student and teacher roles and with the promotion of participation in the educational process.

    Full Text Available Most of brackish water ponds used for seaweed (Gracilaria verrucosa culture in Luwu Regency, South Sulawesi, Indonesia are constructed on acid sulfate soil. Despite this inevitable condition, opportunities remain open to increase the seaweed production. The research was conducted to study the dominant factors that affect the seaweed production in ASS-affected ponds of Luwu Regency. As a dependent variable in this research is seaweed production. Independent variables were grouped into: (a farmer status factor, consisting of 9 variables; (b pond condition factor, consisting of 8 variables; (c pond management factor, consisting of 29 variables; (d soil quality factor, consisting of 17 variables and (e water quality factor, consisting of 11 variables. Multiple regression with dummy variable was used to analyze the data in prediction dependent variable. Results show that the average of seaweed production in ASS-affected pond of Luwu Regency is 11,000 kg dry/ha/year. Seaweed production can be increased through: (a decreasing dosage of urea and KCl and increasing dosage and frequency of fertilizer containing phosphate; (b increasing water depth in the pond and decreasing percentage of water exchange,(c conducting remediation to increase the soil pH and decreasing the concentration of Fe in the water, (d increasing stocking density of milkfish to decrease the epiphyte population and (e increasing the frequency of the farmer to attend trainings.

    Full Text Available Smartphones are used to access a wide range of different information and communication services and perform functions based on data transfer. A number of subscription contracts for smartphones is rapidly increasing, and the development of mobile communications network provides higher speed of data transfer. The continuous increase in the average amount of data traffic per one subscriber contract leads to an increase in the total Mobile Data Traffic (MDT, globally. This research represents a summary of factors that affect the amount of smartphone MDT. Previous literature shows only a few of the factors individually that affect the realization of smartphone MDT. The results of the research clarify the ways which influence the amount of MDT generated by a smartphone. This paper increases the awareness of the users of the methods of generating smartphone MDT. The research also allows users to specify parameters that affect the prediction of generated MDT of a smartphone.

    The US carbon allowance market has different characteristic and price determination process from the EU ETS market, since emitting installations voluntarily participate in emission trading scheme. This paper examines factors affecting the US carbon allowance market. An autoregressive distributed lag model is used to examine the short- and long-run relationships between the US carbon allowance market and its determinant factors. In the long-run, the price of coal is a main factor in the determination of carbon allowance trading. In the short-run, on the other hand, the changes in crude oil and natural gas prices as well as coal price have significant effects on carbon allowance market. (author)

    Eighty percent of patients with chronic mild cerebral ischemia/hypoxia resulting from chronic heart failure or pulmonary disease have cognitive impairment. Overt structural neuronal damage is lacking and the precise cause of neuronal damage is unclear. As almost half of the cerebral energy consumption is used for synaptic transmission, and synaptic failure is the first abrupt consequence of acute complete anoxia, synaptic dysfunction is a candidate mechanism for the cognitive deterioration in chronic mild ischemia/hypoxia. Because measurement of synaptic functioning in patients is problematic, we use cultured networks of cortical neurons from new born rats, grown over a multi-electrode array, as a model system. These were exposed to partial hypoxia (partial oxygen pressure of 150Torr lowered to 40-50Torr) during 3 (n=14) or 6 (n=8) hours. Synaptic functioning was assessed before, during, and after hypoxia by assessment of spontaneous network activity, functional connectivity, and synaptically driven network responses to electrical stimulation. Action potential heights and shapes and non-synaptic stimulus responses were used as measures of individual neuronal integrity. During hypoxia of 3 and 6h, there was a statistically significant decrease of spontaneous network activity, functional connectivity, and synaptically driven network responses, whereas direct responses and action potentials remained unchanged. These changes were largely reversible. Our results indicate that in cultured neuronal networks, partial hypoxia during 3 or 6h causes isolated disturbances of synaptic connectivity.

    Full Text Available The present work looks into the area of English teaching nowadays, considering the post-modern globalization scenario (STIGLITZ, 2004 and the demand to speak such a language, especially for adults. We start by approaching historical and methodological issues, including the post-method (KUMARAVADIVELU, 2003, 2008; LEFFA, 2003, 2008 and the current translingual approach (CANAGARAJAH, 2013, and we also touch on the high rate of failure when one tries to learn English in Brazil, particularly oral production, according to certain research, such as the one periodically conducted by EF (Education First. Then, we hypothesize that a possible cause for a negative result might be related to affective factors (REVUZ, 1998, reflecting upon the possibility of creating affective bonds and relating to the target language in a scenario of encounter and conflict of differences (ROCHA, 2012. Finally, we propose a reflection to the classroom, from a point of view in which language is discourse, (JORDÃO, 2006, 2007, 2013; KRAMSCH, 1998, 2008a, 2008b, 2012, 2013 in order to make students aware of their own and other people’s cultural issues and have a ressignified perspective. As a result, they should feel more comfortable when studying and speaking English towards a better understanding of other cultures.

    We aimed to investigate the diagnostic yield of stool cultures and identify predictive factors for positive cultures in patients with diarrheal illness.A total of 13,327 patients who underwent stool cultures due to diarrheal illness were reviewed. Stool cultures were performed for enteric pathogens, including Salmonella, Shigella, Vibrio, Klebsiella oxytoca, and Yersinia. The culture-positive group was compared with the culture-negative group who were randomly selected from culture negative patients.A total of 196 patients (1.47%) were diagnosed with positive stool culture. In 196 culture positive patients, Salmonella spp. (75.0%) was detected most commonly, followed by Vibrio (19.4%). Univariate analyses showed fever (>37.8°C), vomiting, duration and frequency of diarrhea, and high C-reactive protein (CRP) were significantly associated with positive stool culture. Multivariate analysis showed fever (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.25-4.35; P = .008), ≥5/day of diarrhea (OR, 3.52; 95% CI, 1.93-6.44; P 50 mg/L of CRP (OR, 2.27; 95% CI, 1.18-4.36; P = .014) were independent predictors for positive stool culture. OR in patients with all 3 factors was 6.55 (95% CI, 2.56-16.75; P factor.Diagnostic yield of stool culture in patients with diarrheal illness is very low. Fever, frequency of diarrhea, and high CRP are predictors for positive stool cultures. These findings may lead to more discerning and cost-effective utilization of stool culture by clinicians.

    Full Text Available Binary logit regression model of econometrics was used to identify the factors affecting adoption of recommended agricultural technology by the commercial farmers of Nepal. A survey was carried out in 2012 in 120 households from Kavre district, Nepal. The objective was to appraise factors affecting adoption of recommended technology of cauliflower, finding out the level of adoption, identifying the constraints of cauliflower cultivation, assessing the perceived level of satisfaction and studying the relationship of certain selected variables on the adoption. Education, Occupation, contact with Personal Localite sources of information, Group membership and Experience were the most influencing factors for adoption of recommended technology. Though, other factors were not strong enough to contribute significantly but indirectly influence the adoption decision of farmers as combined effects. Occupation was found as negatively associated. Landholding size was strongly and positively influencing among the non significant factors. The level of satisfaction and the constraints of cauliflower production were also identified. Transfer of technology will be effective if and only if the client adopts the technology. For an effective transfer of technology, it is better to go for activities for the welfare of the socioeconomic factors of the farmers.

    Background: Sex is a complex, important and sensitive issue in human being and interwoven with the whole of human existence. Given the serious changes in attitude, function and behavior in sex, the need to address sexual function, especially sexual satisfaction, is felt completely. Sexual satisfaction has a very important role in creating marital satisfaction and any defect in sexual satisfaction is significantly associated with risky sexual behaviors, serious mental illness, social crimes and ultimately divorce. Aim: The aim of this study was to explore affecting factors on sexual satisfaction in women based on an overview in scientific database. Methods: In this narrative review the researchers searched MEDLINE database, Google Scholar and Science Direct as well as Persian database like Scientific Information Database with search terms of sexual satisfaction and sexual function, restricted to English/ Persian language, during the 20 years ago. Then those articles written by renowned experts were selected. In this regard, 57 articles have been reviewed, which 30 articles related to this research have been extracted. Results: The findings were divided in to four categories including: Demographic factors, Pathophysiological factors, Psychological factors and Sociocultural factors. Conclusions: Sexuality, especially sexual intimacy is sophisticated and yet elegant affair that the other persons has different definitions and different functions. Discrepancies in the results of the studies show that analysis of factors affecting sexual satisfaction regardless of the women’s’ sociocultural context, religious beliefs, and personal attitudes is undoubtedly inefficient, unscientific and irrational.

  17. Factors Affecting Accuracy of Data Abstracted from Medical Records.

    Directory of Open Access Journals (Sweden)

    Meredith N Zozus

    Full Text Available Medical record abstraction (MRA is often cited as a significant source of error in research data, yet MRA methodology has rarely been the subject of investigation. Lack of a common framework has hindered application of the extant literature in practice, and, until now, there were no evidence-based guidelines for ensuring data quality in MRA. We aimed to identify the factors affecting the accuracy of data abstracted from medical records and to generate a framework for data quality assurance and control in MRA.Candidate factors were identified from published reports of MRA. Content validity of the top candidate factors was assessed via a four-round two-group Delphi process with expert abstractors with experience in clinical research, registries, and quality improvement. The resulting coded factors were categorized into a control theory-based framework of MRA. Coverage of the framework was evaluated using the recent published literature.Analysis of the identified articles yielded 292 unique factors that affect the accuracy of abstracted data. Delphi processes overall refuted three of the top factors identified from the literature based on importance and five based on reliability (six total factors refuted. Four new factors were identified by the Delphi. The generated framework demonstrated comprehensive coverage. Significant underreporting of MRA methodology in recent studies was discovered.The framework generated from this research provides a guide for planning data quality assurance and control for studies using MRA. The large number and variability of factors indicate that while prospective quality assurance likely increases the accuracy of abstracted data, monitoring the accuracy during the abstraction process is also required. Recent studies reporting research results based on MRA rarely reported data quality assurance or control measures, and even less frequently reported data quality metrics with research results. Given the demonstrated

    Full Text Available Background: Despite the positive impact of cardiac rehabilitation (CR on quality of life and mortality, the majority of people who could benefit from this program fail to participate in it. The lack of referral from the physician is a common reason that patients give for not seeking CR. The objective of this study was to compare factors affecting CR referral by cardiologists. Methods: A cross-sectional survey of 122 cardiologists, including 89 general cardiac specialists and 33 fellows in cardiology from 11 major cardiology training centers in Iran, was done in 2010. They responded to the 14- item investigator-generated survey, examining the physician’s attitudinal and knowledge factors affecting CR referral. Results: 47.9% of the subjects reported having available CR centers but only 6.6% reported continuous medical education on the topic. 90.7% of the physicians reported that less than 15% of patients are referred to CR centers. The main factor affecting the low referral rate was limited general knowledge about CR programs (79.5% such as program attributes and benefits, methods of reimbursement. Lack of insurance coverage, unavailability of CR centers in the community and low physicians’ fee were other factors reported by the physicians. Conclusion: Cardiologists’ inadequate general knowledge of and attitude toward CR programs seem to be a potential threat for cardiac prevention and rehabilitation in some societies.

    2011-12-01

    Full Text Available Abstract Background The choice between several treatment options for replacing a single missing tooth is influenced by clinical, dentist- and patient-immanent factors. This study aimed to determine the patient factors that would affect the treatment decision to replace a single missing tooth and to assess the satisfaction with several options. Method 200 volunteers involved (121 females and 79 males divided into four groups, Group A: consisted of patients with conventional fixed partial dentures or patients with resin bonded fixed partial dentures. Group B: consisted of patients who received removable partial dentures while Group C: consisted of patients who received a single implant supported crown, and a control group D: consisted of patients who received no treatment. Data were collected using a questionnaire. Results The highest percentage of males within groups (58% was within the removable prostheses category. The majority of the subjects in the study reported that the main reason for replacing a missing tooth was for esthetic and function. Most important factor affecting the choice between treatment modalities was damaging the neighboring teeth. Pain, post operative sensitivity and dental phobia were important factors in choosing the prosthesis type and affected the control group patients not to have any treatment. The highest satisfaction percentage among groups studied was recorded for dental implants then FPD groups, while the least percentage were in both the control and RPD groups, for all aspects of function, esthetic and speech efficiency. Conclusions The final choice between FPD, RPD and implant depended on several factors which affected the decision making; among these is cost and patients' awareness of the different treatment options.

    Yeast cells originating from one single colony are considered genotypically and phenotypically identical. However, taking into account the cellular heterogeneity, it seems also important to monitor cell-to-cell variations within a clone population. In the present study, a comprehensive yeast karyotype screening was conducted using single chromosome comet assay. Chromosome-dependent and mutation-dependent changes in DNA (DNA with breaks or with abnormal replication intermediates) were studied using both single-gene deletion haploid mutants (bub1, bub2, mad1, tel1, rad1 and tor1) and diploid cells lacking one active gene of interest, namely BUB1/bub1, BUB2/bub2, MAD1/mad1, TEL1/tel1, RAD1/rad1 and TOR1/tor1 involved in the control of cell cycle progression, DNA repair and the regulation of longevity. Increased chromosome fragility and replication stress-mediated chromosome abnormalities were correlated with elevated incidence of genomic instability, namely aneuploid events-disomies, monosomies and to a lesser extent trisomies as judged by in situ comparative genomic hybridization (CGH). The tor1 longevity mutant with relatively balanced chromosome homeostasis was found the most genomically stable among analyzed mutants. During clonal yeast culture, spontaneously formed abnormal chromosome structures may stimulate changes in the ploidy state and, in turn, promote genomic heterogeneity. These alterations may be more accented in selected mutated genetic backgrounds, namely in yeast cells deficient in proper cell cycle regulation and DNA repair.

    Full Text Available Cultural differences in the perception of positive affect intensity within an advertising context were investigated among American, Japanese and Russian participants. Participants were asked to rate the intensity of facial expressions of positive emotions, which displayed either subtle, low intensity or salient, high intensity expressions of positive affect. In agreement with previous findings from cross-cultural psychological research, current results demonstrate both cross-cultural agreement and differences in the perception of positive affect intensity across the three cultures. Specifically, American participants perceived high arousal images as significantly less calm than participants from the other two cultures, while the Japanese participants perceived low arousal images as significantly more excited than participants from the other cultures. The underlying mechanisms of these cultural differences were further investigated through difference scores that probed for cultural differences in perception and categorization of positive emotions. Findings indicate that rating differences are due to (1 perceptual differences in the extent to which high arousal images were discriminated from low arousal images, and (2 categorization differences in the extent to which facial expressions were grouped into affect intensity categories. Specifically, American participants revealed significantly higher perceptual differentiation between arousal levels of facial expressions in high and intermediate intensity categories. Japanese participants, on the other hand, did not discriminate between high and low arousal affect categories to the same extent as did the American and Russian participants. These findings indicate the presence of cultural differences in underlying decoding mechanisms of facial expressions of positive affect intensity. Implications of these results for cross-cultural communication and global advertising are discussed.

    One current challenge in microbial ecology is elucidating the functional roles of the large diversity of free-living and host-associated bacteria identified by culture-independent molecular methods. Importantly, the characterization of this immense bacterial diversity will likely require merging data from culture-independent approaches with work on bacterial isolates in culture. Amphibian skin bacterial communities have become a recent focus of work in host-associated microbial systems due to the potential role of these skin bacteria in host defense against the pathogenic fungus Batrachochytrium dendrobatidis (Bd), which is associated with global amphibian population declines and extinctions. As there is evidence that some skin bacteria may inhibit growth of Bd and prevent infection in some cases, there is interest in using these bacteria as probiotic therapy for conservation of at-risk amphibians. In this study, we used skin swabs from American toads (Anaxyrus americanus) to: (1) assess the diversity and community structure of culturable amphibian skin bacteria grown on high and low nutrient culture media, (2) determine which culture media recover the highest proportion of the total skin bacterial community of individual toads relative to culture-independent data, and (3) assess whether the plated communities from the distinct media types vary in their ability to inhibit Bd growth in in-vitro assays. Overall, we found that culture media with low nutrient concentrations facilitated the growth of more diverse bacterial taxa and grew distinct communities relative to media with higher nutrient concentrations. Use of low nutrient media also resulted in culturing proportionally more of the bacterial diversity on individual toads relative to the overall community defined using culture-independent methods. However, while there were differences in diversity among media types, the variation among individual hosts was greater than variation among media types, suggesting that

    Full Text Available In order to combat adverse effects of farmland degradation it is necessary for farmers to adopt sustainable land management and conservation strategies like intercropping and conservation tillage. However, efforts to adopt these strategies are very minimal in Ethiopia. In an attempt to address the objectives of examining factors affecting use of intercropping and conservation tillage practices, this study utilized plot- and household-level data collected from 211 farm households and employed a bivariate probit model for its analysis. The study revealed that intercropping and conservation tillage decisions are interdependent, and that they are also significantly affected by various factors. In addition, conservation tillage and intercropping practices as short- term interventions are found to augment the long-term interventions like terraces, diversion ditches, and tree plantations. The paper highlights important policy implications that are required to encourage intercropping and conservation tillage measures.

    Full Text Available The aim of the review was to analyze the ways of microbial contamination, the protective mechanism of egg, and factors that affect the quantity of contamination and microbial penetration. Eggs can be contaminated during their formation in the infected reproductive organs of hens or after laying, when eggs are exposed to contaminated environment. The eggs are equipped against microbial contamination by several protective mechanisms comprising the presence of cuticle, eggshell, eggshell membranes, occurrence of some antibacterial proteins, and high pH value of albumen. There are several factors that affect the quantity of microbial contamination and penetration such as species of bacteria, the amount of microorganisms, storage conditions, quality of eggshell or number of pores.

    Mechanisms affecting patterns of vector distribution among host individuals may influence the population and evolutionary dynamics of vectors, hosts and the parasites transmitted. We studied the role of different factors affecting the species composition and abundance of Culicoides found in nests of the blue tit (Cyanistes caeruleus). We identified 1531 females and 2 males of 7 different Culicoides species in nests, with C. simulator being the most abundant species, followed by C. kibunensis, C. festivipennis, C. segnis, C. truncorum, C. pictipennis and C. circumscriptus. We conducted a medicationxfumigation experiment randomly assigning bird's nests to different treatments, thereby generating groups of medicated and control pairs breeding in fumigated and control nests. Medicated pairs were injected with the anti-malarial drug Primaquine diluted in saline solution while control pairs were injected with saline solution. The fumigation treatment was carried out using insecticide solution or water for fumigated and control nests respectively. Brood size was the main factor associated with the abundance of biting midges probably because more nestlings may produce higher quantities of vector attractants. In addition, birds medicated against haemoparasites breeding in non-fumigated nests supported a higher abundance of C. festivipennis than the rest of the groups. Also, we found that the fumigation treatment reduced the abundance of engorged Culicoides in both medicated and control nests, thus indicating a reduction of feeding success produced by the insecticide. These results represent the first evidence for the role of different factors in affecting the Culicoides infracommunity in wild avian nests.

    Although emotions have been assumed conventionally to be universal, recent studies have suggested that various aspects of emotions may be mediated by cultural background. The purpose of our research was to test these contradictory views, in the case of the subjective evaluation of visual affective stimuli. We also sought to validate the recently introduced Nencki Affective Picture System (NAPS) database on a different cultural group. Since there has been, to date, no attempt to compare the emotions of a culturally distinct sample of Iranians with those of Europeans, subjective ratings were collected from 40 Iranians and 39 Europeans. Each cultural group was asked separately to provide normative affective ratings and classify pictures according to discrete emotions. The results were analyzed to identify cultural differences in the ratings of individual images. One hundred and seventy NAPS pictures were rated with regard to the intensity of the basic emotions (happiness, sadness, fear, surprise, anger, and disgust) they elicited, as well as in terms of affective dimensions (valence and arousal). Contrary to previous studies using the International Affective Picture System, our results for Europeans and Iranians show that neither the ratings for affective dimensions nor for basic emotions differed across cultural groups. In both cultural groups, the relationship between valence and arousal ratings could be best described by a classical boomerang-shaped function. However, the content of the pictures (animals, faces, landscapes, objects, or people) had a significant effect on the ratings for valence and arousal. These findings indicate that further studies in cross-cultural affective research should control for the content of stimuli. PMID:28316576

    Full Text Available Proteins of the same functional family (for example, kinases may have significantly different lengths. It is an open question whether such variation in length is random or it appears as a response to some unknown evolutionary driving factors. The main purpose of this paper is to demonstrate existence of factors affecting prokaryotic gene lengths. We believe that the ranking of genomes according to lengths of their genes, followed by the calculation of coefficients of association between genome rank and genome property, is a reasonable approach in revealing such evolutionary driving factors. As we demonstrated earlier, our chosen approach, Bubble-sort, combines stability, accuracy, and computational efficiency as compared to other ranking methods. Application of Bubble Sort to the set of 1390 prokaryotic genomes confirmed that genes of Archaeal species are generally shorter than Bacterial ones. We observed that gene lengths are affected by various factors: within each domain, different phyla have preferences for short or long genes; thermophiles tend to have shorter genes than the soil-dwellers; halophiles tend to have longer genes. We also found that species with overrepresentation of cytosines and guanines in the third position of the codon (GC3 content tend to have longer genes than species with low GC3 content.

    This study used an ecological model to examine Thai workers' beliefs and attitudes toward using occupational hearing protection. Data collection involved focus group sessions with 28 noise-exposed workers at four factories in Chiang Mai Province and an interview with a safety officer at each organization. Detailed content analysis resulted in the identification of three types of factors influencing the use of hearing protection: intrapersonal, including preventing impaired hearing, noise annoyance, personal discomfort, and interference with communication; interpersonal, including coworker modeling, supervisor support, and supervisor modeling; and organizational, including organizational rules and regulations, provision of hearing protection devices, dissemination of knowledge and information, noise monitoring, and hearing testing. Effective hearing protection programs depend on knowledge of all of these factors. Strategies to promote workers' use of hearing protection should include the complete range of factors having the potential to affect workers' hearing.

    Enamel wear by ceramics may adversely affect maintenance of the vertical dimension of occlusion and can increase the potential for thermal sensitivity. In this article, factors related to the abrasion of enamel by dental ceramics are critically reviewed. Concepts of physical, microstructural, chemical, and surface characteristics of dental ceramics on wear are presented based on research published since 1950. A PubMed search for key words (wear of enamel and ceramic) was supplemented with a hand search to identify relevant peer-reviewed articles published in English. Based on the literature, it can be concluded that material factors, their proper handling, and control of the patient's intrinsic risk factors related to wear are critically important to the reduction of enamel wear by dental ceramics.

    Background In the past decades, the one-year graft survival of cadaveric renal allografts has been markedly improved,but their long-term survival has not kept pace. The attrition rate of renal allografts surviving after one year remains almost unchanged. The causes for late graft loss are multiple. The aim of this study was to analyze the predictive factors that impact long-term survival of grafts after kidney transplantation.Methods We retrospectively analyzed 524 kidney transplantation patients who were treated in our hospital between January 1991 and January 2000, including 254 patients who had lived more than 10 years with normal graft function (long survival group), and 270 cases whose renal graft had survived less than 10 years (control group). Specifically, we analyzed 10 factors that may potentially affect graft survival by both univariate and Logistic model multivariate analyses to pinpoint the independent risk factors.Results Univariate analyses showed that no significant differences existed in the age or gender of recipients, dialysis time, lymphotoxin levels, or cold ischemia time between the two groups. However, the ratio of delayed graft function and acute rejection, and the uric acid levels of patients in the long survival group were significantly lower than those in the control group (P <0.01). Furthermore, we found that the concentration of cyclosporin A at one year after transplantation and the histocompatibility antigen match of donor-recipients for patients within the long survival group were significantly higher than those in the control group (P <0.01 ). Furthermore, multivariate analyses showed that these four factors were independent risk factors that impact patient survival.Conclusions The ratios of delayed graft function and acute rejection, the concentration of cyclosporin A at one year after transplantation, and serum uric acid levels are very important factors that affect the long-term survival of renal grafts.

    Full Text Available Background and Objective: Multiple sclerosis (MS is a chronic and progressive disease of the central nervous system. The identification of effective factors and patient education on the prevention of exposure to these factors can be effective in reducing relapses. Therefore, the present study aimed to investigate the factors that affect recurrence in patients with multiple sclerosis. Materials and Method: This cross-sectional study was conducted on 402 MS patients referred to the MS Association of Mashhad, Iran, in 2013. The study participants were selected using purposive sampling method. Data collection tools included a demographic questionnaire and a 40-item researcher-made questionnaire concerning factors affecting the recurrence of MS. The 40-item questionnaire consisted of 4 domains personal factors, medical condition, pharmaceutical conditions, and environmental factors. Data analysis was performed using SPSS software version 21 and Mann Whitney, Pearson correlation, Kruskal Wallis, and chi-square statistical tests. Results: Among the patients, 21/4% were male and 78/6% female. Most patients were 20-29 years old. The highest prevalence of recurrence of MS was observed in the summer (70.8% and in August (50.3%. There was no significant relationship between patient’s gender and their views about the relationship between infections, fatigue, and heat and recurrence of MS. However, a higher rate of women believed stress (P < 0.029 and sexual development (P < 0.001 to be effective on the incidence of MS recurrence, in comparison to men. Conclusion: Most patients with MS are women, and they believe stress to be more effective on the incidence of MS attack recurrence. Therefore, nurses, as the primary care educators, can improve the patients’ capability, disease management, and quality of life through training of stress management techniques.

    Full Text Available Wildlife hunting is an important economic activity that contributes to the subsistence of indigenous peoples and the maintenance of their cultural identity. Changes in indigenous peoples' ways of life affect the way they manage the ecosystems and resources around them, including wildlife populations. This paper explores the relationship between cultural change, or detachment from traditional culture, and hunting behaviour among the Tsimane', an indigenous group in the Bolivian Amazon. We interviewed 344 hunters in 39 villages to estimate their hunting activity and the degree of cultural change among them. We used multilevel analyses to assess the relationships between three different proxies for cultural change at the individual level (schooling, visits to a market town, and detachment from tradition, and the following two independent variables: 1 probability of engaging in hunting (i.e., hunting activity and 2 hunting efficiency with catch per unit effort (CPUE. We found a statistically significant negative association between schooling and hunting activity. Hunting efficiency (CPUE biomass/km was positively associated with visits to a market town, when holding other co-variates in the model constant. Other than biophysical factors, such as game abundance, hunting is also conditioned by social factors (e.g., schooling that shape the hunters' cultural system and impel them to engage in hunting or deter them from doing so.

    In this paper, a Jungian understanding of cultural factors influencing individual analysis is illustrated with the case of a patient suffering from panic attacks. The analysis revealed that, in addition to the patient's personal background, the collectivistic attitudes of the Soviet culture, which had a moulding effect on the patient in his childhood and obstructed his individuation, should be taken into account. The concepts of the totalitarian object and the Russian cultural complex encompassing a grandiosity pole and an inferiority pole are used to explore the patient's condition, and the crucial role of creating mutual language with the patient is outlined. © 2016, The Society of Analytical Psychology.

    Identifying traits that affect the reproductive success of individuals is fundamental for our understanding of evolutionary processes. In cooperative breeders, a dominant male typically restricts mating access to the dominant female for extended periods, resulting in pronounced variation in reproductive success among males. This may result in strong selection for traits that increase the likelihood of dominance acquisition, dominance retention and reproductive rates while dominant. However, despite considerable research on reproductive skew, few studies have explored the factors that influence these three processes among males in cooperative species. Here we use genetic, behavioural and demographic data to investigate the factors affecting reproductive success in dominant male meerkats (Suricata suricatta). Our data show that dominant males sire the majority of all offspring surviving to 1 year. A male's likelihood of becoming dominant is strongly influenced by age, but not by weight. Tenure length and reproductive rate, both important components of dominant male reproductive success, are largely affected by group size and composition, rather than individual traits. Dominant males in large groups have longer tenures, but after this effect is controlled, male tenure length also correlates negatively to the number of adult females in the group. Male reproductive rate also declines as the number of intra- and extra-group competitors increases. As the time spent in the dominant position and reproductive rate while dominant explain > 80% of the total variance in reproductive success, group composition thus has major implications for male reproductive success.

    Full Text Available It is known in the literature that the incidence and prevalence of suicide and attempted suicide in psychiatric patients is significantly higher than in the general population. The paper examined risk factors for suicidal behavior in the category of admitted patients hospitalized with the diagnosis of sleep disorders and affective (Unipolar resp. Bipolar depression. Study activated by 80 patients, 40 in both diagnostic groups received treatment at the Special Psychiatric Hospital in Gornja Toponica near Nis. The work methodology used are: psychiatric interview, Hamilton Depression Rating Scale (HAMD, and the C-SSRS (Columbia-Suicide Severity Rating Scale- assessment tool that assesses suicidal ideation and behavior. The study results show that there is a relationship between suicidal behavior (suicide attempts and suicidal ideation and the diagnosis of bipolar affective disorder, positive history of previous suicide attempts, so that these factors are stronger, to the degree of suicidality higher. On this sample, clearly suicidal behavior, with the same purpose, intensity of suicidal thoughts and medical impairment after suicide attempts were significantly more frequent in patients with Bipolar Affective Disorder in the depressive phase of the illness. Patients with a previous suicide attempt, and poor personal and social circumstances had a higher rate of attempted suicide.

  16. An Improved Reinforcement Learning System Using Affective Factors

    2013-07-01

    Full Text Available As a powerful and intelligent machine learning method, reinforcement learning (RL has been widely used in many fields such as game theory, adaptive control, multi-agent system, nonlinear forecasting, and so on. The main contribution of this technique is its exploration and exploitation approaches to find the optimal solution or semi-optimal solution of goal-directed problems. However, when RL is applied to multi-agent systems (MASs, problems such as “curse of dimension”, “perceptual aliasing problem”, and uncertainty of the environment constitute high hurdles to RL. Meanwhile, although RL is inspired by behavioral psychology and reward/punishment from the environment is used, higher mental factors such as affects, emotions, and motivations are rarely adopted in the learning procedure of RL. In this paper, to challenge agents learning in MASs, we propose a computational motivation function, which adopts two principle affective factors “Arousal” and “Pleasure” of Russell’s circumplex model of affects, to improve the learning performance of a conventional RL algorithm named Q-learning (QL. Compared with the conventional QL, computer simulations of pursuit problems with static and dynamic preys were carried out, and the results showed that the proposed method results in agents having a faster and more stable learning performance.

    Background Donor and recipient risk factors on graft function have been well characterized.The contribution of demographic factors,such as age,gender,and other potential factors of donor and recipient at the time of transplantation on the function of a graft is much less well understood.In this study,we analyzed the effects of factors such as age,gender,etc.,on the short-term and long-term graft function in kidney transplant recipients from living donor.Methods A total of 335 living donors and their recipients,who had kidney transplantation in our center from May 2004 to December 2009,were included.Serum creatinine level was used as the assessment criterion (serum creatinine level lower than 115 mmol/L is normal).Factors related to graft function such as age,gender,blood relation by consanguinity,human leukocyte antigen (HLA) mismatch,ABO type,etc.,were analyzed separately.Results Donor age is the key factor affecting both the short-term and long-term function of a grafted kidney from a living donor.The group with donors younger than 48 years showed the best kidney function post transplantation.Match of gender and age is another important factor that influences the function of grafted kidney from a living donor.The older donor to younger recipient group had the worst outcome after kidney transplantation.After 36 months post transplantation,female donor to male recipient group had worse kidney function compared to other groups.We also found that calcinerin inhibitor used in the maintenance period may influence the function of a grafted kidney.No significant statistical differences were found in consanguinity,blood type,and mismatch of HLA.Conclusions Donor age is an important factor affecting the function of a grafted kidney from a living donor.We also recommend taking nephron,immunology factor,infection,and demographic information all into consideration when assessing the outcome of kidney transplantation.

    Full Text Available Abstract Background Exhaled nitric oxide (FENO measurements are used as a surrogate marker for eosinophilic airway inflammation. However, many constitutional and environmental factors affect FENO, making it difficult to devise reference values. Our aim was to evaluate the relative importance of factors affecting FENO in a well characterised adult population. Methods Data were obtained from 895 members of the Dunedin Multidisciplinary Health and Development Study at age 32. The effects of sex, height, weight, lung function indices, smoking, atopy, asthma and rhinitis on FENO were explored by unadjusted and adjusted linear regression analyses. Results The effect of sex on FENO was both statistically and clinically significant, with FENO levels approximately 25% less in females. Overall, current smoking reduced FENO up to 50%, but this effect occurred predominantly in those who smoked on the day of the FENO measurement. Atopy increased FENO by 60%. The sex-related differences in FENO remained significant (p ENO. Conclusion Even after adjustment, FENO values are significantly different in males and females. The derivation of reference values and the interpretation of FENO in the clinical setting should be stratified by sex. Other common factors such as current smoking and atopy also require to be taken into account.

    Full Text Available This study aimed to systematically review the articles on factors affecting sexual function during menopause. Searching articles indexed in Pubmed, Science Direct, Iranmedex, EMBASE, Scopus, and Scientific Information Database databases, a total number of 42 studies published between 2003 and 2013 were selected. Age, estrogen deficiency, type of menopause, chronic medical problems, partner's sex problems, severity of menopause symptoms, dystocia history, and health status were the physical factors influencing sexual function of menopausal women. There were conflicting results regarding the amount of androgens, hormonal therapy, exercise/physical activity, and obstetric history. In the mental–emotional area, all studies confirmed the impact of depression and anxiety. Social factors, including smoking, alcohol consumption, the quality of relationship with husband, partner's loyalty, sexual knowledge, access to health care, a history of divorce or the death of a husband, living apart from a spouse, and a negative understanding of women's health were found to affect sexual function; however, there were conflicting results regarding the effects of education, occupation, socioeconomic status, marital duration, and frequency of sexual intercourse.

It is aimed to provide source to researchers and relevant institutions who are willing to guide the future sectoral initiatives and conduct more extensive research on seafood consumer habits. In this context, the research population was determined according to their distance to the sea and their populations by purposive sampling method. 43 % of total 400 survey was conducted in Ankara, 36% in İzmir and 21% in Adana by face to face interviews. According to the survey results, 6% of respondents never consume seafood, 25% once a month, 28% once every two weeks, and 42% consume once and more than once in a week. The most seafood consumption frequency was identified in Izmir. Nearly 90% of consumers in the entire regions prefer to consume seafood in fresh type. According to the answers of all consumers 4 major factors affecting seafood consumption preferences and habits in a negative way were "high price, cannot be easily found in the market, not recognition of seafood varieties and disfavor of the flavor of seafood". The relationship between frequency of seafood consumption and education level of consumer’s variables is determined as linear and strong but the relationship between consumer age and seafood consumption frequency is determined as reverse. On the factors affecting choice of seafood consumption in a positive way, 71% of consumers stated the beneficial to health perception and taste of seafood as the most important reason for their preference. Therefore, the relationship between consumption trend and beneficial to health perception of seafood is determined as linear and strong.

    Full Text Available This research paper investigates long and short term determinants of fertility rates in Malaysia based on basic macroeconomic variables for the period 1980-2014 using Auto Regressive Distributed Lag (ARDL method. The study reveals that over a long term period, all the selected variables (GDP, infant mortality rate, females’ education and employment have had significant and negative impact on total fertility rates. Whilst during the short term period, only the infant mortality rate has had a positive impact. Since population growth is partly determined by fertility rates, efforts to increase population in Malaysia should consider factors that affect those rates.

    Antlers constitute the only mammal model for limb regeneration. A number of factors affect antler regeneration. In this review, we examine such factors and the potential consequences for organ regeneration. As body mineral stores are depleted to grow antlers, physiological exhaustion is shown in the mineral composition, mechanical performance and, according to preliminary studies, porosity of the antler bone material. Nutrition plays an important role in antler characteristics. Thus, antler composition can be used as a diagnostic tool to assess mineral deficiencies in deer. Studies on ecological effects of exceptional weather in plants suggest that minor minerals, particularly Mn, may play disproportionately roles in mechanical performance of bone material. This suggests that Mn (and perhaps other minerals) is essential to incorporate Ca and P from resorbed skeleton material in antlers. Apart from implications for game management, some effects may have applications for medicine.

    1976-08-01

    Assuming that ultrasonic flowmeters of suitable intrinsic accuracy are feasible, this report explores factors extrinsic to the flowmeter which affect the accuracy such as asymmetric flow profile, regions of high turbulence and thermal stratification. By integrating isovelocity flow profile maps, the predicted performance of various flowmeter configurations may be compared to experimental data. For the two pipe arrangements analyzed, the single diametral path flowmeter results were within 5 percent of true flow rate. Theoretical correction factors could reduce the error for the straight pipe but increased the error for asymmetrical flow. On the same pipe arrangements a four path ultrasonic flowmeter spaced for Gaussian integration gave less than 1 percent error. For more general conclusions a range of flow profiles produced by typical LMFBR piping arrangements must be analyzed.

    Scientific literacy for our students and the possibilities for careers available in Science, Technology, Engineering, and Mathematics (STEM) areas are important topics for economic growth as well as global competitiveness. The achievement of students in science learning is dependent upon the science teachers' effectiveness and experienced science teachers depend upon relevant professional development experiences to support their learning. In order to understand how to improve student learning in science, the learning of science teachers must also be understood. Previous research studies on teacher professional development have been conducted in other states, but Minnesota science teachers comprised a new and different population from those previously studied. The purpose of this two-phase mixed methods study was to identify the current types of professional development in which experienced, Minnesota secondary science teachers participated and the factors that affect their participation in professional development activities. The mixed-methods approach s utilized an initial online survey followed by qualitative interviews with five survey respondents. The results of the quantitative survey and the qualitative interviews indicated the quality of professional development experiences and the factors which affected the science teachers' participation in professional development activities. The supporting and inhibiting factors involved the availability of resources such as time and money, external relationships with school administrators, teacher colleagues, and family members, and personal intrinsic attributes such as desires to learn and help students. This study also describes implications for science teachers, school administrators, policymakers, and professional development providers. Recommendations for future research include the following areas: relationships between and among intrinsic and extrinsic factors, science-related professional development activities

    Full Text Available OBJETIVES: To interpret the perception of the determining factors that influence the diet of a group of intern patients in a drug rehabilitation center in Concepción, Chile, during the year 2015. MATERIAL AND METHODS: Through a qualitative design with a phenomenological approach, intern patients of a drug rehabilitation facility, who fulfilled the study assigned criteria, were interviewed. The collection of data was conducted through semi structured interviews; which were validated by experts and subject to a pilot test. Nonprobability convenience sampling was performed. The sample size was determined through theoretical saturation, which was completed at the eighth interview. The results were subject to triangulation of informants, and were analyzed using the technique of discourse analysis. RESULTS: The participants identify positive and negative factors that condition their diet. They claim that having a fixed schedule is positive since this helps them to have a more organized diet. However, some stressful situations within the facilities are described as limiting factors in their mood, thus affecting their appetite and reducing their food intake. Additionally, not being with their families, especially at the beginning of the treatment, is considered a negative aspect. The lack of variety in terms of food preparation is also negative since this does not correspond to their food preferences. During the drug withdrawal stage, the intake of food containing carbohydrates of rapid absorption was increased. CONCLUSIONS: It is interpreted that the interviewees at the drug rehabilitation facility identify conditioning factors that influence their diet, which promote or inhibit food intake, and affect the attitude they present towards their diet in the drug withdrawal stage.

    Full Text Available Organizations are operating in a dynamic and turbulent environment. In these conditions, they have to make decisions for new problems or situations. Most of decisions are therefore non-programmed and unstructured, accompanied by risk and uncertainty. Moreover, the problems and situations are complex. All organizations are oriented towards group decisionmaking processes, as useful tools to cope with uncertainty and complexity. Apart from the necessity, companies are turning towards participatory processes also to benefit from the important advantages that these processes offer. Organizations have realized the importance of group decision-making processes to contribute to the creation of sustainable competitive advantages. Main objective of this paper is to show that group decision-making processes do not offer guarantee for good decisions, because the effectiveness of group is affected by many factors. So, the first thing done in this paper is discussing about the benefits and limitations that accompany the use of groups with decision-making purpose. Afterwards, we stop on the different factors that influence the group’s ability to make good decisions. The aim is to emphasize that regardless of the many advantages of groups, some factors as group size, type of communication within the group, leadership style, the norms, the differentiation of roles and statuses, cohesion and compliance degree should be the main elements to keep into consideration because they affect the effectiveness of group. In this regard, is discussed how such factors influence the quality of decision and then we try to draw some conclusions that can improve and make better and easier group decision-making processes.

    2015-12-01

    Full Text Available The article examines legal culture as a factor of stability in developing societies referring to the concepts of culture proposed by P.A. Sorokin, L.N. Kogan, M.T. Iovchuk and other famous sociologists. The authors state that in the modern sociological literature legal culture is studied mainly from the theoretical rather than empirical standpoint: the sociology has accumulated a lot of data on the legal culture, although its study in the context of agreements and conflicts, stability and destructiveness is not enough. Legal culture should be regarded as a regulator and stabilizer of social interactions and relationships in both specific countries and the global space. Thus, identifying regional and global aspects of legal culture has become an important theoretical problem of the sociological studies nowadays as well as considering legal culture in relation to moral, economic and political values and priorities. The authors argue that it is not possible to build a state of law and civil society without raising the level of legal culture, and present the results of the sociological study of the legal culture in the south of the Tyumen region conducted in 2013. This survey revealed an average level of following the law in 55% of the local population, although 90% consider themselves law-abiding citizens. At the same time, 46% believe in the possibility to manipulate the law, and 60% approve the principle of equity of the law. The authors conclude that the identified average level of legal culture among the local population is an indicator of a quite stable and successful development of the region under study.

    Ajilian, Hosna

    Understanding the factors which influence adopting sustainability practices in IHE is an important issue to develop more effective sustainability's methods and policies. The focus of this research is to find out a meaningful relationship between adopting sustainability practices and some of the characteristics of institutions of higher education (IHE). IHE can be considered as the best place to promote sustainability and develop the culture of sustainability in society. Thus, this research is conducted to help developing sustainability in IHE which have significant direct and indirect impact on society and the environment. First, the sustainability letter grades were derived from "Greenreportcard.org" which have been produced based on an evaluation of each school in nine main categories including: Administration, Climate Change & Energy, Food & Recycling, etc. In the next step, the characteristics of IHE as explanatory variables were chosen from "The Integrated Postsecondary Education Data System" (IPEDS) and respective database was implemented in STATA Software. Finally, the "ordered-Probit Model" is used through STATA to analyze the impact of some IHE's factor on adopting sustainability practices on campus. The results of this analysis indicate that variables related to "Financial support" category are the most influential factors in determining the sustainability status of the university. "The university features" with two significant variables for "Selectivity" and "Top 50 LA" can be classified as the second influential category in this table, although the "Student influence" is also eligible to be ranked as the second important factor. Finally, the "Location feature" of university was determined with the least influential impact on the sustainability of campuses.

    DeFronzo, James; Prochnow, Jane

    2004-02-01

    Explaining the phenomenon of male serial homicide has usually been approached from a psychiatric perspective. However, recent integrative theory suggests that cultural factors may play a role in shaping the psychology of young males with particular psychiatric and possibly neurological vulnerabilities in such ways as to facilitate converting the motivation to kill into actual behavior. Present results indicated that 34-45% of the interstate variation in rates of serial killer activity could be accounted for by three dimensions of local culture. Higher rates of male serial killer activity were associated with a local state culture supportive of game hunting and military training and a local culture supportive of punitive violence. The findings must be viewed with caution since societal variables are complex and the results are based on correlations which cannot be causally interpreted without more direct evidence of validity.

    To evaluate factors which affect the longevity of tunneled central venous catheters (T-CVCs). A retrospective study was conducted on 363 T-CVCs. We evaluated the relevant factors affecting the longevity of the T-CVCs, such as age, gender, indication for catheterization, site of entry vessel, diameter and type of T-CVC, catheter tip position, and underlying diseases. Of the 363 T-CVCs which had been inserted, 331 (91%) were placed through the right internal jugular vein (RIJV). The catheter tip position was the strongest predictor for the longevity of the T-CVC. The short limb of the catheter tip placed either at the cavoatrial junction (CA junction) or below the lower margin of the right main bronchus had a good prognosis. The vessel through which the T-CVC was placed significantly influenced the longevity of the T-CVC; the RIJV was associated with better results than the left internal jugular vein. Also, a split-type catheter was significantly associated with a better result. A two distinct and separate type T-CVC placed through the RIJV in which the short limb catheter tip position was at the level of the CA junction, significantly increased the longevity of T-CVCs.

    Full Text Available AIM: Women should be healthy and have health promotion behaviors, so they can accomplish both their maternal and social tasks. This descriptive study was conducted to determine the healthy life-style behaviors of married women and the factors which could affect those behaviors. METHOD: The population comprised all married women older than 15 years and who live in Ankara Kale region. Three hundred-sixty five married women were included in the study. The questionnaire form and the healthy life-style behaviors scale was used for data collection. RESULTS: The mean score taken from scale was 112.2±19.4. The scores of the women who graduated from middle school / high school, who have sufficient income and good socio-economic status, who have a perception of physical health fairly good and who have any chronic disease in their families, have significantly higher mean scores from healthy life-style behaviors scale and subgroups (p<0.05 CONCLUSION: Health promotion behaviors of the women was low and some factors like education level, income, socioeconomic status, perception of health, having any chronic illness and using regular medicine affected healthy life-style behaviors. It is recommended that nurses, who have education and consultation roles, should inform the women about health promotion behaviors and encourage them to use that information in their lives.

The population of the study consisted of students between 9th and 12th grades from the Anatolian high schools, science high schools, social sciences high schools, sports high schools and fine arts high schools in Turkey. The sample was chosen through the stratified and cluster sampling procedure. The students were chosen randomly depending on the regions of their school attendance. The sample for this research numbered 3170 students. The research was conducted in the second term of the 2014-2015 academic year. The data were obtained through online forms and the bases of participation are honesty, sincerity, and volunteerism. The data collection tool is a questionnaire and a demographic information form prepared by the researchers. Chi-square Automatic Interaction Detector (CHAID analysis was conducted through SPSS in order to determine the demographic factors affecting the purposes of internet usage among high school students. The results of this research show that 9th grade students in Turkey mostly use the Internet to do homework while students from other grades mostly use the Internet for social networking. The male students use the Internet for playing video games more frequently in comparison with female students. Also, socioeconomic status affects the purpose of Internet usage. Hence it is suggested that teachers talking to male students might use the examples of computers and games and with female students they might relate the topics to social media.

    The quality of fresh-cut fruit and vegetable products includes a combination of attributes, such as appearance, texture, and flavor, as well as nutritional and safety aspects that determine their value to the consumer. Nutritionally, fruit and vegetables represent a good source of vitamins, minerals, and dietary fiber, and fresh-cut produce satisfies consumer demand for freshly prepared, convenient, healthy food. However, fresh-cut produce deteriorates faster than corresponding intact produce, as a result of damage caused by minimal processing, which accelerates many physiological changes that lead to a reduction in produce quality and shelf-life. The symptoms of produce deterioration include discoloration, increased oxidative browning at cut surfaces, flaccidity as a result of loss of water, and decreased nutritional value. Damaged plant tissues also represent a better substrate for growth of microorganisms, including spoilage microorganisms and foodborne pathogens. The risk of pathogen contamination and growth is one of the main safety concerns associated with fresh-cut produce, as highlighted by the increasing number of produce-linked foodborne outbreaks in recent years. The pathogens of major concern in fresh-cut produce are Listeria monocytogenes, pathogenic Escherichia coli mainly O157:H7, and Salmonella spp. This article describes the quality of fresh-cut produce, factors affecting quality, and various techniques for evaluating quality. In addition, the microbiological safety of fresh-cut produce and factors affecting pathogen survival and growth on fresh-cut produce are discussed in detail.

    Unexpected increase in cost and delays in construction projects are caused by owner, contractor, environments, etc. in which several types of risk factors may occur concurrently. The effect of cost overrun and schedule overrun do not only influence the construction industry but the overall economy as well. Even though construction project increasing in cost and schedule has received extensive attention of researchers, but because of continuous changes and development in the field, the study considered of added value to the construction industry in Egypt, in addition to risk strategy and plan analysis. In order to meet the deadline of a project and due to the complex nature of construction projects, cost and scheduling should be flexible enough to accommodate changes without negatively affecting the overall project cost and duration. As such, the objectives of the presented research in this paper are to identify, study, and assess the effect of the factors that affect cost and time contingency. Data are collected from sixteen construction companies in Egypt. The collected data, output charts and analyses spreadsheets will be used for the development of computerized model built by the authors with identification abbreviation RIAM.

    Full Text Available Objective: The aim of the study was the evaluation of patients treated with a diagnosis of gastroschisis and to establish the factors which affected the morbidity and mortality.Methods: Twenty-nine patients, managed for gastroschisis during 2000-2010 were reviewed retrospectively.Patients were analysed in respect to gestational age, birth weight, associated anomalies, type of delivery,operative procedures, postoperative complications, total parenteral nutrition (TPN related complications.The factors affecting mortality and morbidity were determined.Findings: Associated abnormalities were present in 24% of the patients. Eleven patients underwent elective reduction in the incubator (Bianchi procedure without anesthesia. Eight patients had delayed reduction with silo and ten patients had primary closure. Although the type of delivery had an effect on morbidity but notmortality, gestational age, birth weight, and the operative procedure performed had no effect on morbidity or mortality. Duration until tolerance of oral intake, and of TPN and hospitalization were found to be statistically significantly shorter in the group of babies delivered by cesarean section.Conclusion: In our study the most important cause of mortality was the abdominal compartment syndrome and multi-organ failure in the early years. Long hospitalization periods and sepsis were the main causes of mortality in recent years.

    Full Text Available This cross-sectional study explores factors affecting the decision of basketball players to wear ankle support devices (ASDs. A questionnaire regarding attitudes towards ASD usage was developed based on the Health Belief Model (HBM. The questionnaire assessed HBM perceptions (susceptibility, severity, benefits, and barriers and modifying factors (demographic, personal history of ankle injury, influence of coach to preventive action that may affect an athlete’s decision to wear ASDs. One hundred forty basketball players competing at the recreational, high school, or university levels completed the questionnaire, with the questionnaires being completed at the basketball gymnasium or at home. It was found that athletes whose coaches enforced ASD use were significantly more likely to wear them (OR: 35.71; 95% CI: 10.01, 127.36, as were athletes who perceived ankle injuries to be severe (OR: 2.77; 95% CI: 1.04, 7.37. Previous injury did not significantly increase the odds of using an ASD. The combined influence of coach enforcement and previous injury had the greatest effect on increasing ASD use. The largest barrier to ASD use was a lack of aesthetic appeal. Strategies aimed at increasing players’ willingness to wear ankle protection should be emphasized among coaches and parents as this may increase use of ASDs.

    The purpose of this study was to clarify the factors affecting the quality of life (QOL) of the elderly home-bound patients. Data were collected from 56 chronically disabled elderly persons (mean age of 76.7 years) who needed a long-term home-based care. They were assessed on QOL, range of activity, functional capacity, and capacity of family care functioning as well as socio-economic condition. The QOL was evaluated by using Philadelphia Geriatric Center Morale Scale (PGC Morale Scale). The activities of daily living (ADL) and handicaps were evaluated by the Barthel index and the ESCROW profile, respectively. The capacity of family care functioning was also recorded according to the "Family Care Scale" developed by Hamamura. As a result, there was a significant difference between PGC Morale Scale score and Barthel index score (P QOL of the home-bound elderly disabled were determined by the motivation, functional capacity, and capacity of family care functioning (P QOL, ADL must be improved, therefore, rehabilitation should be continued to maintain their function after discharging from hospitals and that we should take these factors into consideration, such as living environments and social conditions of the family care. The results also indicate how the patient's independence in the daily life influences social and economic status, and consequently it affects the quality of life.

    This study investigated the moderating effects of several Global Leadership and Organizational Behavior Effectiveness (GLOBE) cultural value dimensions on the relationship between employees' perceptions of their organization's social responsibility and their affective organizational commitment. Based on data from a sample of 1,084 employees from 17 countries, results showed that perceived corporate social responsibility (CSR) was positively related to employees' affective commitment (AC), after controlling for individual job satisfaction and gender as well as for nation-level differences in unemployment rates. In addition, several GLOBE value dimensions moderated the effects of CSR on AC. In particular, perceptions of CSR were more positively related to AC in cultures higher in humane orientation, institutional collectivism, ingroup collectivism, and future orientation and in cultures lower in power distance. Implications for future CSR research and cross-cultural human resources management are discussed. (c) 2012 APA, all rights reserved.

    Full Text Available Weather affects the demography of animals and thus climate change will cause local changes in demographic rates. In birds numerous studies have correlated demographic factors with weather but few of those examined variation in the impacts of weather in different seasons and, in the case of migrants, in different regions. Using capture-recapture models we correlated weather with apparent survival of seven passerine bird species with different migration strategies to assess the importance of selected facets of weather throughout the year on apparent survival. Contrary to our expectations weather experienced during the breeding season did not affect apparent survival of the target species. However, measures for winter severity were associated with apparent survival of a resident species, two short-distance/partial migrants and a long-distance migrant. Apparent survival of two short distance migrants as well as two long-distance migrants was further correlated with conditions experienced during the non-breeding season in Spain. Conditions in Africa had statistically significant but relatively minor effects on the apparent survival of the two long-distance migrants but also of a presumably short-distance migrant and a short-distance/partial migrant. In general several weather effects independently explained similar amounts of variation in apparent survival for the majority of species and single factors explained only relatively low amounts of temporal variation of apparent survival. Although the directions of the effects on apparent survival mostly met our expectations and there are clear predictions for effects of future climate we caution against simple extrapolations of present conditions to predict future population dynamics.

    1994-01-01

    The authors explore factors that affect electricity trade between enterprises in the US and Canada and the US and Mexico. They look to those underlying policy and institutional factors that affect the relative costs of producing electricity in the three countries. In particular, they consider six factors that appear to have a significant impact on electricity trade in North America: differences in the types of economic regulation of power leading to differences in cost recovery for wholesale and retail power and wheeling charges; changing regulatory attitudes, placing more emphasis on demand-side management and environmental concerns; differences in energy and economic policies; differences in national and subnational environmental policies; changing organization of electric power industries which may foster uncertainty, change historical relationships, and provide other potentially important sources of power for distribution utilities; and differences in the ability of enterprises to gain access to electric power markets because of restrictions placed on transmission access. In Section 2, the authors discuss the regulation of electricity trade in North America and provide an overview of the recent trading experience for electricity between Canada and the US and between Mexico and the US, including the volume of that trade over the past decade and existing transmission capacity between regions of the three countries. In Section 3, they look at the benefits that accrue to trading counties and what those benefits are likely to be for the three countries. The discussion in Section 4 centers on the relevant provisions of the Canada Free Trade Agreement and the proposed North American Free Trade Agreement. In Section 5, they set the stage for the discussion of policy and institutional differences presented in Section 6 by outlining differences in the organization of the electric power sectors of Canada, the US, and Mexico. The study is synthesized in Section 7.

    Full Text Available Background Cardiovascular diseases are a leading cause of morbidity and mortality in solid organ transplant recipients. In addition, low physical activity is a risk factor for cardiac and cerebrovascular complications. Objectives This study examined potential relationships between physical activity, health-related quality of life (HRQoL, risk factors for cardiovascular disease, and an exercise test in liver-graft recipients. Patients and Methods A total of 107 participants (62 men/45 women who had received a liver transplantation (LT at least 6 months previously were evaluated. Physical activity was assessed using three different questionnaires, while HRQoL was assessed using the medical outcomes study short form (SF-36 questionnaire, and health behaviors were evaluated using the health behavior inventory (HBI. The exercise test was performed in a standard manner. Results Seven participants (6.5% had a positive exercise test, and these individuals were older than those who had a negative exercise test (P = 0.04. A significant association between a negative exercise test and a higher level of physical activity was shown by the Seven-day physical activity recall questionnaire. In addition, HRQoL was improved in various domains of the SF-36 in participants who had a negative exercise test. No correlations between physical activity, the exercise test and healthy behaviors, as assessed via the HBI were observed. Conclusions Exercise test performance was affected by lower quality of life and lower physical activity after LT. With the exception of hypertension, well known factors that affect the risk of coronary artery disease had no effect on the exercise test results.

  20. Factors affecting economies of scale in combined sewer systems.

    A generic model is introduced that represents the combined sewer infrastructure of a settlement quantitatively. A catchment area module first calculates the length and size distribution of the required sewer pipes on the basis of rain patterns, housing densities and area size. These results are fed into the sewer-cost module in order to estimate the combined sewer costs of the entire catchment area. A detailed analysis of the relevant input parameters for Swiss settlements is used to identify the influence of size on costs. The simulation results confirm that an economy of scale exists for combined sewer systems. This is the result of two main opposing cost factors: (i) increased construction costs for larger sewer systems due to larger pipes and increased rain runoff in larger settlements, and (ii) lower costs due to higher population and building densities in larger towns. In Switzerland, the more or less organically grown settlement structures and limited land availability emphasise the second factor to show an apparent economy of scale. This modelling approach proved to be a powerful tool for understanding the underlying factors affecting the cost structure for water infrastructures.

  1. Dietary Factors Affecting Thyroid Cancer Risk: A Meta-Analysis.

    2015-01-01

    Some dietary factors are proposed to affect thyroid carcinogenesis, but previous studies have reported inconsistent findings. Therefore, we performed a meta-analysis, including 18 eligible studies, to clarify the role of dietary factors in the risk of thyroid cancer. The relative risks (RRs) with 95% confidence intervals (95% CIs) were estimated to assess the association and heterogeneity tests and subgroup and sensitivity analyses, and bias assessments were performed. When the results from all studies were combined, dietary iodine, fish, and cruciferous vegetable intake were not associated with thyroid cancer. However, when the data were divided by geographic location based on iodine availability, a slight increase in the risk of thyroid cancer was observed among those consuming a high total amount of fish in iodine nondeficient areas (RR: 1.18; 95% CI: 1.03-1.35; P for heterogeneity = 0.282). When excluding the studies examining a single food item and hospital-based controls, a high intake of cruciferous vegetables was associated with an increased risk of thyroid cancer in iodine-deficient areas (RR: 1.43; 95% CI: 1.18-1.74; P for heterogeneity = 0.426). This meta-analysis implies that the role of dietary factors, such as fish and cruciferous vegetables, in thyroid cancer risk can differ based on iodine availability.

    The purpose of this study was to identify factors that affect the adjustment of women and their husbands to recurrent breast cancer and to examine the mutual effect that partners have on one another. An exploratory study was designed to determine the relationship between four predictor variables (support, uncertainty, symptom distress, hopelessness) and women's and husbands' adjustments. The sample consisted of 155 subjects; 81 women, who had a first recurrence of breast cancer, and 74 husbands. Multiple standardized instruments with established reliability and validity were used to measure the study variables. The independent variables were measured with the Social Support Questionnaire, the Mishel Uncertainty in Illness Scale, McCorkle Symptom Distress Scale and the Beck Hopelessness Scale. The dependent variable, psychosocial adjustment, was measured with the Brief Symptom Inventory and the Psychosocial Adjustment to Illness Scale. The results indicated that the independent variables accounted for 43% of the variance in women's distress and 32% of the variance in husbands' distress; they also explained 66% of the variance in women's role adjustment problems and 57% of the variance in husbands' role problems. Symptom distress and hopelessness accounted for the most variance in women's and husbands' levels of adjustment. A significant and positive relationship was found between women's and husbands' adjustment scores, indicating that partners have a mutual influence on one another. The findings suggest that there are multiple factors that influence couples' adjustment to recurrent breast cancer, and that these factors need to be taken into consideration when planning care for women and their partners.

    2015-01-01

    Full Text Available This study uses data from different periods, areas and parameters of airborne LiDAR (light detection and ranging surveys to understand the factors that influence airborne LiDAR penetration rate. A discussion is presented on the relationships between these factors and LiDAR penetration rate. The results show that the flight height above ground level (AGL does not have any relationship with the penetration rate. There are some factors that should have larger influence. For example, the laser is affected by a wet ground surface by reducing the number of return echoes. The field of view (FOV has a slightly negative correlation with the penetration rate, which indicates that the laser incidence angle close to zero should achieve the best penetration. The vegetation cover rate also shows a negative correlation with the penetration rate, thus bare ground and reduced vegetation in the aftermath of a typhoon also cause high penetration rate. More return echoes could be extracted from the full-waveform system, thereby effectively improving the penetration rate. This study shows that full-waveform LiDAR is an effective method for increasing the number of surface reflected echoes. This study suggests avoiding LiDAR survey employment directly following precipitation to prevent laser echo reduction.

    Our aim was to evaluate the factors affecting the mortality of patients who underwent nontraumatic major lower limb amputation due to ischemic and/or diabetic causes. A total of 100 patients were included in the study. Among these patients, 70 (70%) underwent below-knee amputation, whereas 30 (30%) underwent above-knee amputation. Eleven (15.7%) of the 70 patients who underwent below-knee amputation and 12 (40%) of the 30 patients who underwent above-knee amputation (P = .008) were deceased. After multivariable Poisson regression analysis, female gender (risk ratio [RR] = 2.00, 95% CI = 1.07-3.74) and a neutrophil lymphocyte ratio (NLR) less than 6.8 (RR = 5.12, 95% CI = 1.86-14.08) were found to be independent risk factors for mortality. The value of 6.8 was used as a cutoff point for the NLR (area under the curve = 0.73, 95% CI = 0.62-0.85), with a sensitivity, specificity, positive predictive value, and negative predictive value of 83%, 66%, 57%, and 92%, respectively. The NLR and female gender were found to be independent factors that are related to increased mortality in patients who underwent lower limb amputation due to diabetic and/or ischemic causes. The coexistence of congestive heart failure and the amputation level (above knee) were found to be predictors of mortality in univariable analysis, but significance could not be demonstrated in multivariable analysis. © The Author(s) 2016.

    Prior to 1994, plantar fascia ruptures were considered as an acute injury that occurred primarily in athletes. However, plantar fascia ruptures have recently been reported in the setting of preexisting plantar fasciitis. We analyzed risk factors causing plantar fascia rupture in the presence of preexisting plantar fasciitis. We retrospectively reviewed 286 patients with plantar fasciitis who were referred from private clinics between March 2004 and February 2008. Patients were divided into those with or without a plantar fascia rupture. There were 35 patients in the rupture group and 251 in the nonrupture group. The clinical characteristics and risk factors for plantar fascia rupture were compared between the 2 groups. We compared age, gender, the affected site, visual analog scale pain score, previous treatment regimen, body mass index, degree of ankle dorsiflexion, the use of steroid injections, the extent of activity, calcaneal pitch angle, the presence of a calcaneal spur, and heel alignment between the 2 groups. Of the assessed risk factors, only steroid injection was associated with the occurrence of a plantar fascia rupture. Among the 35 patients with a rupture, 33 had received steroid injections. The odds ratio of steroid injection was 33. Steroid injections for plantar fasciitis should be cautiously administered because of the higher risk for plantar fascia rupture.

    Full Text Available Equine embryo production by intracytoplasmic sperm injection (ICSI is currently effective enough to be used clinically. However, there are several factors that affect the efficiency of this procedure because, in addition to specialized equipment, skill in oocyte and embryo handling, and sperm preparation as well as knowledge of oocyte and embryo culture are required. To the best of our knowledge, there are currently only a couple of reports available on the expected efficiency of foal production by ICSI. Here we discuss the parameters that pertain to the Texas A&M Equine Embryo Laboratory only, as other laboratories may have different results.

    A cyanobacterium isolated from a source-water reservoir during a spring odor and taste episode and identified as Anabaena sp. consistently produced geosmin during laboratory culture on modified BG-11 liquid medium. Maximal geosmin/biomass occurred at 20 degrees C and a light intensity of 17 microE/m2/s; geosmin/chla values directly correlated with increasing light intensity (r2 = 0.95, P geosmin synthesis; at 17 microE/m2/s, increasing temperature stimulates chla production (to 25 degrees C) while repressing geosmin synthesis (above 20 degrees C). Nutritional factors promoting biomass, chla, and geosmin synthesis by Anabaena sp. were also investigated. For cultures grown at 17 microE/m2/s and 20 degrees C for 20 days, both ammonium-N and nitrate-N generally enhanced the growth of Anabaena sp. Nitrate-N promoted more chla production (r2 = 0.99) than ammonium-N. Geosmin synthesis was directly correlated with ammonium-N concentrations (r2 = 0.89), with low nitrate-N (123.5 micrograms/l) favoring maximal geosmin production (2.8 micrograms/l). Increasing nitrate-N concentrations promoted a three-fold increase in chla content with geosmin synthesis decreased by two-fold. Geosmin/mg biomass was directly related to ammonium-N concentration; high nitrate-N levels suppressed geosmin production. No geosmin was detected at or below 118 micrograms phosphate-phosphorus/l. Geosmin, dry weight biomass, and chla production were correlated with increasing phosphorus (P) concentration (r2 = 0.76, 0.96 and 0.98, respectively). No geosmin was detected when copper was present in growth media at or above 6.92 micrograms Cu2+/l (CuSO4.5H2O). Dry weight biomass and chla production were negatively correlated with Cu2+ ion concentrations.

    Full Text Available Recently, the system of care for endangered children has changed from the institutional as well as legislative point of view. In one of the partial areas of ongoing changes, research activities realised within the Students’ Grant Competition called The Factors Affecting the Form of Substitute Family Care are being focused. We deal with this topic because various forms of substitute family care are distinguished in the Czech Republic, where children are placed for various reasons, but we do not know the correct context of such placements. The main aim of the realised research was to find out the frequency of choosing a given form of placing children in substitute family care according to followed variables. The research sample of the quantitative research was consisted of children placed in one of the forms of substitute family care in the Moravian-Silesian region.

    Potential factors affecting retention of pregnancy during weeks 5-9 of gestation were studied in dairy cows and heifers (N = 211) on two farms. Cows were examined by ultrasonography for presence of a viable embryo, and sizes of the corpus luteum (CL) and of follicles > or = 5mm were recorded. Blood samples were taken at each examination and assayed for progesterone and estradiol. Overall pregnancy loss was 11.4%. Cows with two CL did not have greater concentrations of progesterone than cows with one CL and they retained fewer pregnancies (P Embryos that were lost apparently died before CL regression. Retention of pregnancy declined in cows with high body condition and as age of the cow increased. Pregnancy retention was lower in cows bred to one of four frequently-used service sires (P body condition and service sire.

    This descriptive survey research was undertaken to design appropriate programs for the creation of a positive perception of nanotechnology among their intended beneficiaries. In order to do that, the factors affecting positive perceptions were defined. A stratified random sample of 278 science board members was selected out of 984 researchers who were working in 22 National Agricultural Research Institutions (NARIs). Data were collected by using a mailed questionnaire. The descriptive results revealed that more than half of the respondents had "low" or "very low" familiarity with nanotechnology. Regression analysis indicated that the perceptions of Iranian NARI Science Board Members towards nanotechnology were explained by three variables: the level of their familiarity with emerging applications of nanotechnology in agriculture, the level of their familiarity with nanotechnology and their work experiences. The findings of this study can contribute to a better understanding of the present situation of the development of nanotechnology and the planning of appropriate programs for creating a positive perception of nanotechnology.

    2014-09-01

    The rate of enzymatic hydrolysis of cellulose reaction is known to decrease significantly as the reaction proceeds. Factors such as reaction temperature, time, and surface area of substrate that affect cellulose conversion were analyzed relative to their role in a mechanistic model based on first order inactivation of adsorbed cellulases. The activation energies for the hydrolytic step and inactivation step were very close in magnitude: 16.3 kcal mol(-1) for hydrolysis and 18.0 kcal mol(-1) for inactivation, respectively. Therefore, increasing reaction temperature would cause a significant increase in the inactivation rate in addition to the catalytic reaction rate. Vmax,app was only 20% or less of the value at 72 h compared to at 2h as a result of inactivation of adsorbed cellulases, suggesting prolonged hydrolysis is not an efficient way to improve cellulose hydrolysis. Hydrolysis rate increased with corresponding increases in available substrate surface binding area. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2016-05-01

    Drug abuse has been widely linked to suicide risk. We examined the factors that affect adolescent drug users' suicide attempts in South Korea. This study analyzed the data of 311 adolescents who had used drugs such as inhalants, psychotropic drugs, and marijuana (195 males and 116 females). Among 311 subjects, 109 (35.0%) had attempted suicide during the last 12 months. After adjusting for other variables, depressive mood (OR=19.79) and poly-drug use (OR=2.79), and low/middle levels of academic achievement compared with a high level (OR=3.72 and 4.38) were independently associated with increased odds of a suicide attempt, while better perceived health (OR=0.32) was independently associated with reduced odds of a suicide attempt. For adolescent drug users, preventive work should be directed toward the active treatment of drug use, depression, and physical health and reinforcing proper coping strategies for academic and other stress.

    Full Text Available In this paper we explore factors potentially affecting the size of Albanian insurance market, over the period 1999 to 2009. The results of co- integration regression show that GDP and fraction urban population, both one lagged value, size of population and paid claims, both at contemporary value, have significant positive effect on aggregate insurance premium in Albania while the market share of the largest company in the insurance market, one lagged value, has significant negative effect on aggregate insurance premiums. Granger causality test shows statistically significance contribution of GDP growth to insurance premium growth, GDP drives insurance premium growth but not vice versa. The Albanian insurance market is under development, indicators as: insurance penetration, premium per capita, ect are still at low level and this can justify the insignificant role of the insurance in the economy

    Child mortality is a composite indicator reflecting economic, social, environmental, healthcare services, and their delivery situation in a country. Globally, Pakistan has the third highest burden of fetal, maternal, and child mortality. Factors affecting child mortality in Pakistan are investigated by using Binary Logistic Regression Analysis. Region, education of mother, birth order, preceding birth interval (the period between the previous child birth and the index child birth), size of child at birth, and breastfeeding and family size were found to be significantly important with child mortality in Pakistan. Child mortality decreased as level of mother's education, preceding birth interval, size of child at birth, and family size increased. Child mortality was found to be significantly higher in Balochistan as compared to other regions. Child mortality was low for low birth orders. Child survival was significantly higher for children who were breastfed as compared to those who were not.

    This descriptive correlational study explored the predictive validity of the Braden Scale and factors affecting it A Braden score was determined within 4 hours of admission for 50 adult medical/surgical inpatients. Independent skin assessments were made three times a week and at discharge. Fourteen patients (28%) developed pressure ulcers. A Braden score cutoff of 18 or less resulted in a 71% sensitivity, 83% specificity, 63% predictive value of a positive test, and 88% predictive value of a negative test. Three of the four patients incorrectly predicted to be not at risk scored "inadequate" on the nutrition subscale. Two of the four also were underweight. Of the six patients incorrectly predicted at risk for a pressure ulcer, three had been placed on air mattresses and were receiving levothyroxine (Synthroid). This study provides further evidence of the Braden Scale's predictive validity. The results suggest that patients who are underweight or getting inadequate nutrition be considered at increased risk for pressure ulcers.

    To examine factors which affect local recurrence of osteoid osteomas treated with percutaneous CT-guided radiofrequency thermocoagulation. A prospective study was carried out on 45 patients with osteoid osteoma who underwent percutaneous radiofrequency thermocoagulation with a minimum follow-up of 12 months There were seven local recurrences (16%); all occurred within the first year. Local recurrence was significantly related to a non-diaphyseal location (P<0.01). There was no significant relationship (P=0.05) between local recurrence and age of the patient, duration of symptoms, previous treatment, size of the lesion, positive biopsy, radiofrequency generator used or the number of needle positions. There were no complications. Osteoid osteomas in a non-diaphyseal location are statistically more likely to recur than those in a diaphyseal location when treated with CT-guided percutaneous radiofrequency thermocoagulation. This relationship between local recurrence and location has not been previously reported. (orig.)

  3. Factors affecting characterization of bulk high-temperature superconductors

    1997-11-01

    Three major factors affect the characterization of bulk high-temperature superconductors in terms of their levitation properties during interaction with permanent magnets. First, the appropriate parameter for the permanent magnet is internal magnetization, not the value of the magnetic field measured at the magnet`s surface. Second, although levitation force grows with superconductor thickness and surface area, for a given permanent magnet size, comparison of levitation force between samples is meaningful when minimum values are assigned to the superconductor size parameters. Finally, the effect of force creep must be considered when time-averaging the force measurements. In addition to levitational force, the coefficient of friction of a levitated rotating permanent magnet may be used to characterize the superconductor.

    2015-11-01

    Full Text Available The behavior of constructions under actual operating conditions is affected by exposure to the environment. It is important that concrete roads and airport pavings are resistant not only to mechanical damage, but also to the effects of alternate freezing and thawing. The causes of early failure in concrete have been shown using prefabricated road slabs as an example. The causes of loss of performance properties of the roadway have been established, which are primarily dependent on the quality of raw materials in the concrete. It was found that, aside from durability, uniformity and porosity are important factors in determining the frost resistance of concrete roadways. It was shown that high aluminate content in the cement leads to concrete destruction in the first year of structure use. The results may also indirectly indicate a violation of forming technology during slab production.

    We examined the effect of individual environmental factors on the current spruce tree growth assessed from a repeated country-level statistical landscape (incl. forest) survey in the Czech Republic. An extensive set of variables related to tree size, competition, site characteristics including soil texture, chemistry, N deposition and climate was tested within a random-effect model to explain growth in the conditions of dominantly managed forest ecosystems. The current spruce basal area increment was assessed from two consecutive landscape surveys conducted in 2008/2009 and six years later in 2014/2015. Tree size, age and competition within forest stands were found to be the dominant explanatory variables, whereas the expression of site characteristics, environmental and climatic drives was weaker. The significant site variables affecting growth included soil C/N ratio and soil exchangeable acidity (pH KCl; positive response) reflecting soil chemistry, long-term N-deposition (averaged since 1975) in combination with soil texture (clay content) and Standardized Precipitation Index (SPI), a drought index expressing moisture conditions. Sensitivity of growth to N-deposition was positive, although weak. SPI was positively related to and significant in explaining tree growth when expressed for the growth season. Except SPI, no significant relation of growth was determined to altitude-related variables (temperature, growth season length). We identified the current spruce growth optimum at elevations about 800ma.s.l. or higher in the conditions of the country. This suggests that at lower elevations, limitation by a more pronounced water deficit dominates, whereas direct temperature limitation may concern the less frequent higher elevations. The mixed linear model of spruce tree growth explained 55 and 65% of the variability with fixed and random effects included, respectively, and provided new insights on the current spruce tree growth and factors affecting it within the

    While some obese children are metabolically healthy (MHO), some have additional health problems, such as hypertension, dyslipidemia, insulin resistance, and hepatosteatosis, which increase mortality and morbidity related to cardiovascular diseases (CVD) during adulthood. These children are metabolically unhealthy obese (MUO) children. In this study we assessed the factors that affect metabolic health in obesity and the clinical and laboratory findings that distinguish between MHO and MUO children. In total, 1085 patients aged 6-18 years, with age- and sex-matched BMI exceeding the 95th percentile were included in the study (mean 11.1±2.9 years, 57.6% female, 59.7% pubertal). Patients without dyslipidemia, insulin resistance, hepatosteatosis, or hypertension were considered as MHO. Dyslipidemia was defined as total cholesterol level over 200 mg/dL, triglyceride over 150 mg/dL, LDL over 130 mg/dL, or HDL under 40 mg/dL. Insulin resistance was calculated using the homeostasis model of assesment for insulin resistance (HOMA-IR) index. Hepatosteatosis was evaluated with abdominal ultrasound. Duration of obesity, physical activity and nutritional habits, screen time, and parental obesity were questioned. Thyroid and liver function tests were performed. Six hundred and forty-two cases (59.2%) were MUO. Older age, male sex, increased BMI-SDS, and sedentary lifestyle were associated with MUO. Excessive junk food consumption was associated with MUO particularly among the prepubertal obese patients. Our results revealed that the most important factors that affect metabolic health in obesity are age and BMI. Positive effects of an active lifestyle and healthy eating habits are prominent in the prepubertal period and these habits should be formed earlier in life.

    Full Text Available Intervertebral disc (IVD degeneration is strongly associated with low back pain, a major cause of disability worldwide. An in-depth understanding of IVD cell physiology is required for the design of novel regenerative therapies. Accordingly, aim of this work was the study of IVD cell responses to mitogenic growth factors in a three-dimensional (3D organotypic milieu, comprising characteristic molecules of IVD’s extracellular matrix. In particular, annulus fibrosus (AF cells were cultured inside collagen type-I gels, while nucleus pulposus (NP cells in chondroitin sulfate A (CSA supplemented collagen gels, and the effects of Platelet-Derived Growth Factor (PDGF, basic Fibroblast Growth Factor (bFGF, and Insulin-Like Growth Factor-I (IGF-I were assessed. All three growth factors stimulated DNA synthesis in both AF and NP 3D cell cultures, with potencies similar to those observed previously in monolayers. CSA supplementation inhibited basal DNA synthesis rates, without affecting the response to growth factors. ERK and Akt were found to be phosphorylated following growth factor stimulation. Blockade of these two signaling pathways using pharmacologic inhibitors significantly, though not completely, inhibited growth factor-induced DNA synthesis. The proposed culture systems may prove useful for further in vitro studies aiming at future interventions for IVD regeneration.

    Full Text Available Informal payments are a signifi cant source for fi nancing health systems in many developing and transition countries. The aim of our study was the assessment of the infl uence of patients’ socioeconomic status on their informal payment for health care. This article presents a cross-sectional and applied research that was conducted in a general public hospital in Iran during April 2014. The population of the study was all the 1,035 patients discharged during April 2014. Data gathering was done using a questionnaire. An ordered logistic regression model based on a truncated method was estimated to investigate factors affecting informal health payments. About 48% of respondents reported at least one experience of informal payment for health care during the previous year. The results showed that the patients’ socioeconomic status can signifi cantly affect the likelihood and frequency of informal payments for health care. Older people, members of small and wealthier families, employed persons, and those who are under coverage of only basic medical insurance are more at risk of making such payments. Policymakers should pay more attention to such socioeconomic groups in order to improve the effectiveness of policies.

  11. Factors affecting daughter cells' arrangement during the early bacterial divisions.

    Directory of Open Access Journals (Sweden)

    Pin-Tzu Su

    Full Text Available On agar plates, daughter cells of Escherichia coli mutually slide and align side-by-side in parallel during the first round of binary fission. This phenomenon has been previously attributed to an elastic material that restricts apparently separated bacteria from being in string. We hypothesize that the interaction between bacteria and the underneath substratum may affect the arrangement of the daughter bacteria. To test this hypothesis, bacterial division on hyaluronic acid (HA gel, as an alternative substratum, was examined. Consistent with our proposition, the HA gel differs from agar by suppressing the typical side-by-side alignments to a rare population. Examination of bacterial surface molecules that may contribute to the daughter cells' arrangement yielded an observation that, with disrupted lpp, the E. coli daughter cells increasingly formed non-typical patterns, i.e. neither sliding side-by-side in parallel nor forming elongated strings. Therefore, our results suggest strongly that the early cell patterning is affected by multiple interaction factors. With oscillatory optical tweezers, we further demonstrated that the interaction force decreased in bacteria without Lpp, a result substantiating our notion that the side-by-side sliding phenomenon directly reflects the strength of in-situ interaction between bacteria and substratum.

    Summary: In order to investigate whether cultured normal human lens epithelial cells (LEC) express transforming growth factor β (TGF-β), reverse transcriptase polymerase chain reaction (RTPCR) and immunohistochemical methods were used for detection of TGF-β mRNA and protein in cultured normal human LEC. The results showed that a single RT-PCR amplified product about 310bp was obtained, and the sequence was homologous to the known sequence. TGF-β immunostain was positive in the plasma of LEC. It was suggested that normal human LEC could produce TGF-β, and LEC could be affected by TGF-β through autocrine action.

    Highlights: • Vitality was lower in old than in young culture and amount of sucrose differed. • Cd stimulated ROS more than Ni in both cultures but NO was not extensively affected. • Cd accumulated more than Ni but old culture contained more Cd and Ni than young. • Phytochelatin 2 strongly increased under Cd and ascorbic acid under Cd and high Ni. • Young culture contained more acids and mainly citrate differed under metal excess. - Abstract: Responses of Scenedesmus quadricauda grown in vitro and differing in age (old culture—13 months, young culture—1 month) to short-term cadmium (Cd) or nickel (Ni) excess (24 h) were compared. Higher age of the culture led to lower amount of chlorophylls, ascorbic acid and glutathione but higher signal of ROS. Surprisingly, sucrose was detected using DART-Orbitrap MS in both old and young culture and subsequent quantification confirmed its higher amount (ca. 3-times) in the old culture. Cd affected viability and ROS amount more negatively than Ni that could arise from excessive Cd uptake which was also higher in all treatments than in respective Ni counterparts. Surprisingly, nitric oxide was not extensively different in response to age or metals. Strong induction of phytochelatin 2 is certainly Cd-specific response while Ni also elevated ascorbate content. Krebs cycle acids were more accumulated in the young culture but they were rather elevated in the old culture (citric acid under Ni excess). We conclude that organic solid ‘Milieu Bristol’ medium we tested is suitable for long-term storage of unicellular green algae (also successfully tested for Coccomyxa sp. and Parachlorella sp.) and the impact of age on metal uptake may be useful for bioremediation purposes.

    Full Text Available AbstractVibrio cholerae can enter into a viable but non-culturable (VBNC state in order to survive in unfavourable environments. In this study, we studied the roles of five physicochemical and microbiological factors or states, namely, different strains, growth phases, oxygen, temperature, and starvation, on the development of VBNC of V. cholerae in artificial sea water (ASW. Different strains of the organism, the growth phase, and oxygen levels affected the progress of VBNC development. It was found that the VBNC state was induced faster in V. cholerae serogroup O1 classical biotype strain O395 than in O1 El Tor biotype strains C6706 and N16961. When cells in different growth phases were used for VBNC induction, stationary-phase cells lost their culturability more quickly than exponential-phase cells, while induction of a totally non-culturable state took longer to achieve for stationary-phase cells in all three strains, suggesting that heterogeneity of cells should be considered. Aeration strongly accelerated the loss of culturability. During the development of the VBNC state, the culturable cell count under aeration conditions was almost 106-fold lower than under oxygen-limited conditions for all three strains. The other two factors, temperature and nutrients-rich environment, may prevent the induction of VBNC cells. At 22°C or 37°C in ASW, most of the cells rapidly died and the culturable cell count reduced from about 108 CFU/mL to 106–105 CFU/mL. The total cell counts showed that cells that lost viability were decomposed, and the viable cell counts were the same as culturable cell counts, indicating that the cells did not reach the VBNC state. VBNC state development was blocked when ASW was supplied with Luria-Bertani broth (LB, but it was not affected in ASW with M9, suggesting that specific nutrients in LB may prevent the development of VBNC state.

    Vibrio cholerae can enter into a viable but non-culturable (VBNC) state in order to survive in unfavorable environments. In this study, we studied the roles of five physicochemical and microbiological factors or states, namely, different strains, growth phases, oxygen, temperature, and starvation, on the development of VBNC of V. cholerae in artificial sea water (ASW). Different strains of the organism, the growth phase, and oxygen levels affected the progress of VBNC development. It was found that the VBNC state was induced faster in V. cholerae serogroup O1 classical biotype strain O395 than in O1 El Tor biotype strains C6706 and N16961. When cells in different growth phases were used for VBNC induction, stationary-phase cells lost their culturability more quickly than exponential-phase cells, while induction of a totally non-culturable state took longer to achieve for stationary-phase cells in all three strains, suggesting that heterogeneity of cells should be considered. Aeration strongly accelerated the loss of culturability. During the development of the VBNC state, the culturable cell count under aeration conditions was almost 10(6)-fold lower than under oxygen-limited conditions for all three strains. The other two factors, temperature and nutrients-rich environment, may prevent the induction of VBNC cells. At 22 or 37°C in ASW, most of the cells rapidly died and the culturable cell count reduced from about 10(8) to 10(6)-10(5) CFU/mL. The total cell counts showed that cells that lost viability were decomposed, and the viable cell counts were the same as culturable cell counts, indicating that the cells did not reach the VBNC state. VBNC state development was blocked when ASW was supplied with Luria-Bertani broth (LB), but it was not affected in ASW with M9, suggesting that specific nutrients in LB may prevent the development of VBNC state.

    To determine factors that influence the job satisfaction of Saudi nurses. Saudi Arabia has a chronic shortage of Saudi national nurses. This research contributes to a greater understanding of how job satisfaction influences the recruitment and retention of Saudi nationals within the nursing profession. Qualitative data were gathered from Saudi nurses and content analysis was used to identify themes in the written responses. Four main themes emerged from the data: lack of educational opportunities and support and the poor image of the nursing profession, perceptions of favouritism, high workloads and stressful work environment and the effect of religion on job satisfaction. Saudi nurses would be more satisfied with their jobs if they had greater access to educational opportunities and if there was a reduction in workload and the perceived favouritism in the workplace was addressed. Religion was also found to play a significant role in supporting job satisfaction. These findings suggest the development of educational scholarships, as well as policies that better support equity in the workplace, to address Saudi nurses' level of job satisfaction. The generally positive impact of cultural and religious beliefs is also highlighted in this study. © 2015 John Wiley & Sons Ltd.

    Full Text Available Banks are important cells in the economy as they have a significant role by maintaining and encouraging the development of economic sectors. They refocus the resources from those who have surplus to those which have a deficit. Therefore, as any other enterprises, performance is highly desirable for banks and, then, it is crucial to discover what the main factors that influence this objective are. So, this paper analyzes the microeconomic factors affecting bank’s financial performance focusing on 11 entities for the period between 2003 and 2013. The performance is measured by return on assets. The independent variables used are bank’s size, financial leverage,loans to assets ratio, deposits to assets ratio, number of employees, liquidity, net result and monetary policy rate. The results show that bank’s size, loans to assets ratio and liquidity have not a significant impact on performance. Financial leverage has a negative impact, meanwhile the number of employees, deposits to assets ratio and net result have a positive effect.

    The aim of this study was to systematically investigate the literature for articles referring exclusively to the duration of orthodontic therapy and to explore the various factors that could affect this. A Medline search from 1990 to the first week of March 2005 was conducted, the Cochrane Database for Systematic Reviews was utilized, five orthodontic journals were hand searched, the abstracts of related articles were reviewed to search for any relevant studies that might have been missed, and the reference lists of the retrieved articles were hand assessed. Eligibility was determined by reading the reports identified by the search. The end result of this search provided 41 articles. Although there is a need for more conclusive research, the present review revealed several conclusions concerning the duration of orthodontic treatment: (1) there are indications that extraction treatment lasts longer than the non-extraction therapy; (2) age does not seem to play a role provided the patients are in the permanent dentition; (3) when Class II division 1 malocclusions are considered, there is evidence that the earlier the orthodontic treatment begins the longer its duration; (4) there is conflicting information regarding treatment duration within public health systems; (5) combined orthodontic-surgical treatment duration is variable and appears to be operator sensitive; (6) various factors, such as the technique employed, the skill and number of operators involved, the compliance of the patients, and the severity of the initial malocclusion, all seem to play a role; and (7) impacted maxillary canines appear to prolong treatment.

  1. Factors affecting production rates of cosmogenic nuclides in extraterrestrial matter

    2015-10-15

    Good production rates are needed for cosmic-ray-produced nuclides to interpret their measurements. Rates depend on many factors, especially the pre-atmospheric object’s size, the location of the sample in that object (such as near surface or deep inside), and the object’s bulk composition. The bulk composition affects rates, especially in objects with very low and very high iron contents. Extraterrestrial materials with high iron contents usually have higher rates for making nuclides made by reactions with energetic particles and lower rates for the capture of thermal neutrons. In small objects and near the surface of objects, the cascade of secondary neutrons is being developed as primary particles are being removed. Deep in large objects, that secondary cascade is fully developed and the fluxes of primary particles are low. Recent work shows that even the shape of an object in space has a small but measureable effect. Work has been done and continues to be done on better understanding those and other factors. More good sets of measurements in meteorites with known exposure geometries in space are needed. With the use of modern Monte Carlo codes for the production and transport of particles, the nature of these effects have been and is being studied. Work needs to be done to improve the results of these calculations, especially the cross sections for making spallogenic nuclides.

    Full Text Available In order to rectify environmental degradation, government has encouraged sustainable management among businesses. In addition, researchers have also suggested a new breed of study called “sustainable entrepreneurship”, which links sustainability management to entrepreneurial activities. However, the participation of entrepreneurial firms in sustainability management is still far from satisfactory. Past studies also have found that SMEs are less active in sustainabilty initiatives and many issues related to the intention of firms for sustainability entrepreneurship is still unanswered. Therefore, this study was carried out to examine the influence of socio-cultural factors on intention towards sustainable entrepreneurship among SMEs. A total of 404 SMEs in Malaysia were surveyed by using questionnaire. Based on the statistical analyses performed, this study found that three socio-cultural factors, namely time orientation, sustainability orientation and social norm significantly influenced intention towards sustainable entrepreneurship among SMEs. Thus, in order to develop true sustainable entrepreneurs in the country, the effects of non-economic factors such as socio-cultural factors should not be underestimated. Lastly, some recommendations for future researchers have also been put forth in this paper.

  4. Factors Affecting Growth of Pinus radiata in Chile

    Alvarez-Munoz, Jose Santos

    The Chilean forestry industry is based on hundreds of thousands of hectares of Pinus radiata plantations that have been established in a variety of soil and climate conditions. This approach has resulted in highly variable plantation productivity even when the best available technology was used. Little information is known about the ecophysiology basis for this variability. We explored the spatial and temporal variation of stand growth in Chile using a network of permanent sample plots from Modelo Nacional de Simulacion de Pino radiata. We hypothesized that the climate would play an important role in the annual variations in productivity. To answer these questions we developed the following projects: (1) Determination of site resource availability from historical data from automatic weather stations (rainfall, temperatures) and a geophysical model for solar irradiation, (2) Determination of peak annual leaf area index (LAI) for selected permanent sample plots using remote sensing technologies, (3) Analysis of soil, climate, canopy and stand factors affecting the Pinus radiata plantation growth and the use efficiency of site resources. For project 1, we estimated solar irradiation using the r.sun , Hargreaves-Samani (HS), and Bristow-Campbell (BC) models and validated model estimates with observations from weather stations. Estimations from a calibrated r.sun model accounted for 94% of the variance (r2=0.94) in monthly mean measured values. The r.sun model performed quite well for a wide range of Chilean conditions when compared with the HS and BC models. Our estimates of global irradiation may be improved with better estimates of cloudiness as they become available. Our model was able to provide spatial estimates of daily, weekly, monthly and yearly solar irradiation. For project 2, we estimated the inter-annual variation of LAI (Leaf Area Index), using remote sensing technologies. We determined LAI using Landsat Thematic Mapper (TM) data covering a 5 year period

    Identifying causes of declines and evaluating effects of management practices on persistence of local populations of burrowing owls (Athene cunicularia) requires accurate estimates of abundance and population trends. Moreover, regulatory agencies in the United States and Canada typically require surveys to detect nest burrows prior to approving developments or other activities in areas that are potentially suitable for nesting burrowing owls. In general, guidelines on timing of surveys have been lacking and surveys have been conducted at different times of day and in different stages of the nesting cycle. We used logistic regression to evaluate 7 factors that could potentially affect probability of a surveyor detecting a burrowing owl nest. We conducted 1,444 detection trials at 323 burrowing owl nests within 3 study areas in Washington and Wyoming, USA, between February and August 2000-2002. Detection probability was highest during the nestling period and increased with ambient temperature. The other 5 factors that we examined (i.e., study area, time of day, timing within the breeding season, wind speed, % cloud cover) interacted with another factor to influence detection probability. Use of call-broadcast surveys increased detection probability, even during daylight hours when we detected >95% of owls visually. Optimal timing of surveys will vary due to differences in breeding phenology and differences in nesting behavior across populations. Nevertheless, we recommend ???3 surveys per year: one that coincides with the laying and incubation period, another that coincides with the early nestling period, and a third that coincides with the late nestling period. In northern latitudes, surveys can be conducted throughout the day.

    The aim of this study was to determine the factors affecting mortality rate among patients with an electrical burn. A total of 115 patients admitted to the emergency department and hospitalized in the Burn Treatment Center or Intensive Care Unit (ICU) due to the electrical burn, were included in the study. A total of 115 patients (4 female and 111 male) with a mean age of 32.88±12.87 years were included in the study. The mean hospitalization period was 25.03±20.50 days, and the mean total body surface area burned (% TBSA) was 22.83±15.54%. Among those patients, 9 (8.5%) expired, and the remaining 106 were discharged after treatment. In a logistic regression analysis, TBSA >20% (p=0.02, OR: 11.7, CI: 1.38-99.16); ICU requirement (p=0.005, OR: 1.28, CI: 1.08-1.58); erythrocyte transfusion requirement (p=0.02, OR: 12.48, CI: 1.44-107.83); fresh frozen plasma (FFP) requirement (p=0.03, OR: 10.23, CI: 1.18-88.17); albumin requirement (p=0.02, OR: 12.60, CI: 1.44-109.85); admission serum albumin level patients with electrical burns. In clinical practice, defining a mortality risk analyzer using these factors may be helpful in the management of patients with electrical burns. Additional, more comprehensive studies are required to define the risk factors for mortality and long-term morbidities in patients with electrical burns.

    Full Text Available Globally, the responsible factors for the ongoing development of urbanization are the high speed of population growth, and the mass migration of humans to cities and large urban areas. In most countries, this process resulted in the emergence of ‘pseudo-urbanization’ which is difficult to be regulated. The purpose of the carried researches to determine the development priorities in the territory of Greater Baku – the capital city of the Republic of Azerbaijan; to define the problems that take place in this connection; and to develop ways of elimination of these problems. The reason of taking Baku as a research area is connected with some of the factors. Firstly, studies on Baku have been conducted based on the Soviet geographical and urban planning school and their methods for a long period. In this regard, it is necessary to carry out research in this field based on the principles adopted in most countries. Secondly, since 1992, the intensive accumulation of population in the territory of the capital city and the surrounding areas is being observed because of socio-economic problems. As a result, the process of pseudo-urbanization intensified, entailing a densely-populated area. Thirdly, low-rise buildings still continue to exist in the large areas within the territory of Baku, and they are not associated with the functional structure of the city. This situation creates many challenges, particularly in terms of density growth and effective use of the city’s territory. Finally, numerous new buildings have been constructed in the residential areas of Baku in recent years, and this may entailserious problems in water supply, energy provision, and utilities. The study is carried out referring to previous works of researchers, statistic data, and the results of the population census conducted in 1959-2009.The practical significance of the scientific work is that positive and negative factors affecting the further development of Greater Baku

    Full Text Available Indigenous people across the world experience more health related problems as compared to the population at large. So, this review article is broadly an attempt to highlight the important factors for indigenous peoples’ health problems, and to recommend some suggestions to improve their health status. Standard database for instance, Pubmed, Medline, Google scholar, and Google book searches have been used to get the sources. Different key words, for example, indigenous people and health, socio-economic and cultural factors of indigenous health, history of indigenous peoples’ health, Australian indigenous peoples’ health, Latin American indigenous peoples’ health, Canadian indigenous peoples’ health, South Asian indigenous peoples’ health, African indigenous peoples’ health, and so on, have been used to find the articles and books. This review paper shows that along with commonplace factors, indigenous peoples’ health is affected by some distinctive factors such as indigeneity, colonialand post-colonial experience, rurality, lack of governments’ recognition etc., which nonindigenous people face to a much lesser degree. In addition, indigenous peoples around the world experience various health problems due to their varied socio-economic and cultural contexts. Finally, this paper recommends that the spiritual, physical, mental, emotional, cultural, economic, socio-cultural and environmental factors should be incorporated into the indigenous health agenda to improve their health status.

    Inversions of EM data are complicated by a number of factors that need to be taken into account. These factors might contribute by tens of percents in data values, concealing responses from target objects, which usually contribute at the level of few percents only. We developed the exact analytical solutions of the EM wave equations that properly incorporate the contributions of the following effects: 1) A finite source size effect, where conventional dipole (zero-size) approximation brings 10-40% error compare to a real size source, needed to provide adequate signal-to-noise ratio. 2) Complex topography. A three-parametrical approach allows to keep the data misfits in 0.5% corridor while topography effect might be up to 40%. 3) Grounding shadow effect, caused by return ground currents, when Tx-line vicinity is horizontally non-uniform. By keeping survey setup within some reasonable geometrical ratios, the shadow effect comes to just one frequency-independent coefficient, which can be excluded from processing by using logarithmical derivatives. 4) Layer's wide spectral range effect. This brings to multi-layer spectral overlapping, so each frequency is affected by many layers; that requires wide spectral range processing, making the typical 'few-frequency data acquisition' non-reliable. 5) Horizontal sensitivity effect. The typical view at the target signal, reflected from a Tx-Rx mid-point is valid only for a ray approximation, reliable in a far-field zone. Unlike this, the real EM surveys usually work in near-field zone. Thus Tx-Rx mid-point does not represent the layer, so a sensitivity distribution function must be computed for each layer for the following 3D-unification process. 6) Wide range Rx-directions from mid-line Tx. Survey terrain often prevents placing Rx perpendicular to Tx-line, and even small deviations without proper corrections cause a significant inaccuracy. A radical simplification of the effect's description becomes possible after applying a

    People may hold different understandings of race that might affect how they respond to the culture of groups deemed to be racially distinct. The present research tests how this process is moderated by the minority individual's lay theory of race. An essentialist lay theory of race (i.e., that race reflects deep-seated, inalterable essence and is indicative of traits and ability) would orient racial minorities to rigidly adhere to their ethnic culture, whereas a social constructionist lay theory of race (i.e., that race is socially constructed, malleable, and arbitrary) would orient racial minorities to identify and cognitively assimilate toward the majority culture. To test these predictions, the authors conducted 4 studies with Asian American participants. The first 2 studies examine the effect of one's lay theory of race on perceived racial differences and identification with American culture. The last 2 studies tested the moderating effect of lay theory of race on identification and assimilation toward the majority American culture after this culture had been primed. The results generally supported the prediction that the social constructionist theory was associated with more perceived similarity between Asians and Americans and more consistent identification and assimilation toward American culture, compared with the essentialist theory.

    In this study, we investigated the effect of cell density on the proliferation activity of human mesenchymal stem cells (MSCs) derived from adipose tissue (AT-MSCs) over time in culture. Passage #4 (P4) and #12 (P12) AT-MSCs from two donors were plated at a density of 200 (culture condition 1, CC1) or 5000 (culture condition 2, CC2) cells cm(-2) . After 7 days of incubation, P4 and P12 AT-MSCs cultured in CC1 were thin and spindle-shaped, whereas those cultured in CC2 had extensive cell-to-cell contacts and an expanded cell volume. In addition, P4 and P12 AT-MSCs in CC1 divided more than three times, while those in CC2 divided less than once on average. Flow cytometric analysis using 5(6)-carboxyfluorescein diacetate N-succinimidyl ester dye showed that the fluorescence intensity of AT-MSCs was lower in CC1 than in CC2. Furthermore, expression of proliferation-associated genes, such as CDC45L, CDC20A and KIF20A, in P4 AT-MSCs was higher in CC1 than in CC2, and this difference was also observed in P12 AT-MSCs. These data demonstrated that cell culture density affects the proliferation activity of MSCs, suggesting that it is feasible to design a strategy to prepare suitable MSCs using specific culture conditions.

    A review of the nursing literature reveals many undergraduate nursing students lack proficiency with basic mathematical skills, those necessary for safe medication preparation and administration. Few studies exploring the phenomenon from the undergraduate nursing student perspective are reported in the nursing literature. The purpose of this study was to explore undergraduate nursing students’ perceptions of math abilities, factors that affect math abilities, the use of math in nursing, and the extent to which specific math skills were addressed throughout a nursing curriculum. Polya’s Model for Problem Solving and the Bloom’s Taxonomy of Educational Objectives, Affective Domain served as the theoretical background for the study. Qualitative and quantitative methods were utilized to obtain data from a purposive sample of undergraduate nursing students from a private university in western Pennsylvania. Participants were selected based on the proficiency level with math skills, as determined by a score on the Elsevier’s HESI™ Admission Assessment (A2) Exam, Math Portion. Ten students from the “Excellent” benchmark group and eleven students from the “Needing Additional Assistance or Improvement” benchmark group participated in one-on-one, semi-structured interviews, and completed a 25-item, 4-point Likert scale survey that rated confidence levels with specific math skills and the extent to which these skills were perceived to be addressed in the nursing curriculum. Responses from the two benchmark groups were compared and contrasted. Eight themes emerged from the qualitative data. Findings related to mathematical approach and confidence levels with specific math skills were determined to be statistically significant.

    The burden of tuberculosis on the public health is staggering. Worldwide, annual incidence of new cases is estimated to be about 8 million. Almost 3 million deaths occur yearly. Early case identification and adherence to treatment regimens are the remaining barriers to successful control. In many nations, however, fewer than half those with active disease receive a diagnosis, and fewer than half those beginning treatment complete it. The twin problems of delay in seeking treatment and abandonment of a prescribed regimen derive from complex factors. People's confusion as to the implications of the tuberculosis symptoms, costs of transportation to clinic services, the social stigma that attaches to tuberculosis, the high cost of medication, organizational problems in providing adequate followup services, and patients' perception of clinic facilities as inhospitable all contribute to the complexity. Sociocultural factors are emphasized in this report because hitherto they have not been adequately explored. Salient among those sociocultural factors is the health culture of the patients. That is, the understanding and information people have from family, friends, and neighbors as to the nature of a health problem, its cause, and its implications. A knowledge of the health culture of their patients has become a critical tool if tuberculosis control programs are to be successful. Several anthropological procedures are recommended to help uncover the health culture of people served by tuberculosis clinics.

    Full Text Available Background: Multiple sclerosis (MS is a demyelinating disease which can cause many disabilities for the patient. Recent data suggests that MS patients have higher risk for osteoporosis. This study was performed to investigate if the osteoporosis prevalence is higher in MS patients and to determine the possible factors affecting bone mineral density (BMD.Methods: 51 definite relapsing-remitting MS patients according to McDonald's criteria (45 females, 6 males aged between 20 and 50 years participated in this study. The control group included 407 females aged from 20 to 49 years; they were healthy and had no history of the diseases affecting bone metabolism. Femoral and lumbar BMD were measured by Dual Energy X-ray Absorptiometry (DXA. The disability of MS patients was evaluated by Expanded Disability Status Scale (EDSS. The patient’s quality of life was evaluated by the validated Persian version of multiple sclerosis impact scale (MSIS-29.Results: Patients’ mean age was 36 ± 3.3 years and their mean disease duration was 8.7 ± 1.7 years. The mean EDSS score and the mean body mass index (BMI of the patients were 3 ± 0.9 and 23.5 ± 2.3 kg/m2, respectively. 29% of the patients had never been treated by ß-interferon and 6% of them had not received glucocorticoids (GCs pulses since their MS had been diagnosed. 26% of the patients had a history of fracture.18% of our patients were osteoporotic and 43% of them were osteopenic. Femoral BMD was significantly lower among MS patients than age matched controls (P < 0.001, but lumbar BMD showed no difference. There was no correlation between administration of GCs pulses, interferon and BMD; however, we found a significant correlation between EDSS score, quality of life (QoL, disease duration and BMD of both site.Conclusion: As a result of this study, bone loss inevitably occurs in MS patients. The major factor of BMD loss is immobility. Osteoporosis should be managed as part of MS patients

    Most cases of burns occurring in medical institutions are associated with activities involving heat. It is very difficult to detect these burns. To date, there are few reports on burns occurring in medical institutions. The purpose of this paper was to analyze the etiology of burns occurring in medical institutions and to elucidate the factors affecting burn depth. We conducted a retrospective analysis of the medical records of patients who visited our center from April 2008 to February 2013. This study enrolled all patients with burns occurring in the medical institution during or related to treatment. We excluded burn patients whose burns were not related to treatment (for example, we excluded patients with scalding burns that occurred in the hospital cafeteria and pediatric patients with hot water burns from the water purifier). However, patients with burns that occurred in the recovery room after general anesthesia were included. A total of 115 patients were enrolled in this study. The average patient age was 41.5 years, with more women than men (M:F=31:84). There were 29 cases (25.3%) of superficial burns (first-degree and superficial second-degree) and 86 cases (74.7%) of deep burns (deep second-degree and third-degree). Hot packs were the most common cause of burns (27 cases, 23.5%), followed by laser therapy, heating pads, and grounding pads, accounting for 15 cases each. There were 89 cases (77.4%) of contact burns and 26 cases (22.6%) of non-contact burns. The most common site of burns was the lower extremities (41 cases, 35.7%). The burn site and contact burns were both factors affecting burn depth. The rate of deep burns was higher in patients with contact burns than in those with non-contact burns (odds ratio 4.26) and was associated with lower body burns (odds ratio 2.85). In burns occurring in medical institutions, there is a high probability of a deep burn if it is a contact burn or occurs in the lower body. Therefore, safety guidelines are needed

    Although in Crohn's disease post-operative recurrence is common, the determinants of disease recurrence remain speculative. The aim of this study was to examine factors affecting post-operative recurrence of Crohn's disease. A Medline-based literature review was carried out. The following factors were investigated: age at onset of disease, sex, family history of Crohn's disease,smoking, duration of Crohn's disease before surgery,prophylactic medical treatment (corticosteroids, 5-amino salicylic acid [5-ASA] and immunosuppressants),anatomical site of involvement, indication for surgery (perforating or non-perforating disease), length of resected bowel, anast-omotic technique, presence of granuloma in the specimen, involvement of disease at the resection margin, blood transfusions and postoperative complications. Smoking significantly increases the risk of recurrence (risk is approximately twice as high), especially in women and heavy smokers. Quitting smoking reduces the post-operative recurrence rate. A number of studies have shown a higher risk when the duration of the disease before surgery was short. There were, however, different definitions of 'short' among the studies. Prophylactic cortic-osteroids therapy is not effective in reducing the post-operative recurrence. A number of randomized controlled trials offered evidence of the efficacy of 5-ASA (mesalazine) in reducing post-operative recurrence. Recently, the thera-peutic efficacy of immunosuppressive drugs (azathioprine and 6-mercaptopurine) in the prevention of post-operative recurrence has been investigated and several studies have reported that these drugs might help prevent the recurrence. Further clinical trials would be necessary to evaluate the prophylactic efficacy of immunosuppressants.Several studies showed a higher recurrence rate in patients with perforating disease than in those with non-perforating disease. However, evidence for differing recurrence rates in perforating and non

    Objective The aim of the present study was to investigate the effects of work organisation on the emotional labour withdrawal behaviour of Australian community nurses.Methods Using a paper-based survey, a sample of 312 Australian community nurses reported on their emotional dissonance, withdrawal behaviours (i.e. job neglect, job dissatisfaction, stress-related presenteeism) and work organisation. A model to determine the partial mediation effect of work organisation was developed based on a literature review. The fit of the proposed model was assessed via structural equation modelling using Analysis of Moment Structures (AMOS; IMB).Results Community nurses with higher levels of emotional dissonance were less likely to be satisfied with their job and work organisation and had a higher tendency to exhibit withdrawal behaviours. Work organisational factors mediated this relationship.Conclusion Emotional dissonance can be a potential stressor for community nurses that can trigger withdrawal behaviours. Improving work organisational factors may help reduce emotional conflict and its effect on withdrawal behaviours.What is known about the topic? Although emotional labour has been broadly investigated in the literature, very few studies have addressed the effect of the quality of work organisation on nurses' withdrawal behaviours in a nursing setting.What does this paper add? This paper provides evidence that work organisation affects levels of emotional dissonance and has an effect on job neglect through stress-related presenteeism.What are the implications for practitioners? In order to minimise stress-related presenteeism and job neglect, healthcare organisations need to establish a positive working environment, designed to improve the quality of relationships with management, provide appropriate rewards, recognition and effective workload management and support high-quality relationships with colleagues.

  6. Factors affecting the estimate of primary production from space

    1994-01-01

    Remote sensing of primary production in the euphotic zone has been based mostly on visible-band and water-leaving radiance measured with the coastal zone color scanner. There are some robust, simple relationships for calculating integral production based on surface measurements, but they also require knowledge for photoadaptive parameters such as maximum photosynthesis which currently cannot be obtained from spave. A 17,000-station data set is used to show that space-based estimates of maximum photosynthesis could improve predictions of psi, the water column light utiliztion index, which is an important term in many primary productivity models. Temperature is also examined as a factor for predicting hydrographic structure and primary production. A simple model is used to relate temperature and maximum photosynthesis; the model incorporates (1) the positive relationship between maximum photosynthesis and temperature and (2) the strongly negative relationship between temperature and nitrate in the ocean (which directly affects maximum growth rates via nitrogen limitation). Since these two factors relate to carbon and nitrogen, 'balanced carbon/nitrogen assimilation' was calculated using the Redfield ratio, It is expected that the relationship between maximum balanced carbon assimilation versus temperature is concave-down, with the peak dependent on nitrate uptake kinetics, temperature-nitrate relationships,a nd the carbon chlorophyll ration. These predictions were compared with the sea truth data. The minimum turnover time for nitrate was also calculated using this approach. Lastly, sea surface temperature gradients were used to predict the slope of isotherms (a proxy for the slope of isopycnals in many waters). Sea truth data show that at size scales of several hundred kilometers, surface temperature gradients can provide information on the slope of isotherms in the top 200 m of the water column. This is directly relevant to the supply of nutrients into the surface

    To review factors shaping volunteering in palliative care in Australian rural communities using Australian and International literature. Identify gaps in the palliative care literature and make recommendations for future research. A comprehensive literature search was conducted using Proquest, Scopus, Sage Premier, Wiley online, Ovid, Cochran, Google Scholar, CINAHL and Informit Health Collection. The literature was synthesised and presented in an integrated thematic narrative. Australian Rural communities. While Australia, Canada, the United States (US) and the United Kingdom (UK) are leaders in palliative care volunteer research, limited research specifically focuses on volunteers in rural communities with the least occurring in Australia. Several interrelated factors influence rural palliative care provision, in particular an increasingly ageing population which includes an ageing volunteer and health professional workforce. Also current and models of palliative care practice fail to recognise the innumerable variables between and within rural communities such as distance, isolation, lack of privacy, limited health care services and infrastructure, and workforce shortages. These issues impact palliative care provision and are significant for health professionals, volunteers, patients and caregivers. The three key themes of this integrated review include: (i) Geography, ageing rural populations in palliative care practice, (ii) Psychosocial impact of end-end-of life care in rural communities and (iii) Palliative care models of practice and volunteering in rural communities. The invisibility of volunteers in rural palliative care research is a concern in understanding the issues affecting the sustainability of quality palliative care provision in rural communities. Recommendations for future Australian research includes examination of the suitability of current models of palliative care practice in addressing the needs of rural communities; the recruitment

    Background Proprioception plays an important role in knee movements.Since there are controversies surrounding the overall recovery time of proprioception following surgery,it is necessary to define the factors affecting proprioceptive recovery after anterior cruciate ligament (ACL) reconstruction and to investigate the relationship between proprioception and muscle strength.Methods A total of 36 patients who had their ACL reconstructed with a semitendinosus/gracilis graft (reconstructed group:6 months post-surgery) and 13 healthy adults without any knee injury (control group) were included in the study.Knee proprioception was evaluated with a passive reproduction test.Isokinetic strength was measured using the Biodex System.Statistical analysis was used to compare proprioception of the reconstructed group versus the control group,and to define causal factors,including sex,hamstring/quadriceps ratio,and the course of injury before reconstruction.We also investigated the correlation between the passive reproduction error and quadriceps index.Results There was a significant difference in proprioception between the reconstructed and control groups (P <0.05).When the course of injury before reconstruction was less than 4 months,there was a linear correlation with proprioception 6 months after the operation (r=0.713,P <0.05).There was a positive correlation between post-surgery proprioception and the quadriceps index at 6 months post-surgery.Conclusions Impaired knee proprioception is observed 6 months after ACL reconstruction.Within 4 months of injury,early undertaking of reconstruction is associated with better proprioception outcome.Patients with enhanced proprioception have a better quadriceps index.

    The purpose of this article is to illustrate the importance of socio-cultural factors in risk management and the need to incorporate these factors in a standard, internationally recognized (WTO) framework. This was achieved by analysing the relevance of these factors in three cases. It can be concluded that the pre-eminent role of science in food-related regulatory decisions is debatable. At a risk management level, other factors, such as cultural, social, or economic issues, are often more important than scientific advice in determining policy. There is a need for transparency at an international level as trade barriers are gradually being removed and these other factors are becoming more apparent. Therefore it is important that all the factors implicated in the food safety policy-making process are recognized in a standard framework.

    The aim of the present study was to investigate the effect of some air pollutants and meteorological parameters on the survivability of airborne fungi. Fungi were collected by using a slit impactor sampler calibrated to draw 20 L/min, for 3 min. Nitrogen dioxide (NO(2)), sulfur dioxide (SO(2)), particulate matter (PM), relative humidity (RH %), temperature (T °C) and wind speed (WS) were also measured. Air samples were taken during the period from March 2006 to February 2007. Fungal concentrations ranged between 45 and 451 CFU/m(3) with an annual mean concentration of 216 CFU/m(3). The lowest fungal concentration was found in the summer, however the highest one was found in the autumn. NO(2,) SO(2) and PM averaged 83.66 μg/m(3), 67.01 μg/m(3), and 237.69 μg/m(3), respectively. T °C was positively and negatively correlated with Aspergillus (P = 0.000) and Penicillium (P = 0.007), respectively. RH% was positively correlated with total fungi (P = 0.001), Aspergillus (P = 0.002) and Cladosporium (P = 0.047). Multiple regression analysis showed that T °C and RH% were the most predicted variants. Non-significant correlations were found between fungal concentrations and air pollutants. Meteorological parameters were the critical factors affecting fungal survivability.

    Full Text Available Niger faces many natural and human constraints explaining the erratic evolution of its agricultural production over time. Unfortunately, this is likely to cause a decline in the food supply. This study attempts to identify factors affecting rural households’ resilience to food insecurity in Niger. For this, we first create a resilience index by using principal component analysis and later apply structural equation modeling to identify its determinants. Data from the 2010 National Survey on Households’ Vulnerability to Food Insecurity done by the National Institute of Statistics is used. The study shows that asset and social safety net indicators are significant and have a positive impact on households’ resilience. Climate change approximated by long-term mean rainfall has a negative and significant effect on households’ resilience. Therefore, to strengthen households’ resilience to food insecurity, there is a need to increase assistance to households through social safety nets and to help them gather more resources in order to acquire more assets. Furthermore, early warning of climatic events could alert households, especially farmers, to be prepared and avoid important losses that they experience anytime an uneven climatic event occurs.

    This article is concerned with identifying economic factors primarily that affect birth rates in Czech Republic. To find the relationship between the magnitudes, we used the multivariate regression analysis and for modeling, we used a time series of annual values (1994-2011) both economic indicators and indicators related to demographics. Due to potential problems with apparent dependence we first cleansed all series obtained from the Czech Statistical Office using first differences. It is clear from the final model that meets all assumptions that there is a positive correlation between birth rates and the financial situation of households. We described the financial situation of households by GDP per capita, gross wages and consumer price index. As expected a positive correlation was proved for GDP per capita and gross wages and negative dependence was proved for the consumer price index. In addition to these economic variables in the model there were used also demographic characteristics of the workforce and the number of employed people. It can be stated that if the Czech Republic wants to support an increase in the birth rate, it is necessary to consider the financial support for households with small children.

    Sufficient consultation time is important for establishing good doctor-patient relationship. We examined the factors that affect consultation length in Japanese diabetes practice. This was a cross-sectional study performed at a diabetes clinic in central Tokyo, Japan. Regular diabetes consultations of 1197 patients with 22 physicians were analyzed. Consultation time and clinical characteristics were obtained from the electronic records. A negative binomial model, which included patient and physician characteristics, was constructed to examine the association of the variables with consultation length. Of the 1197 patients (mean age, 66; women, 25%; type 1 diabetes, 10%), the mean consultation time was 10.1min. In the multivariate model, longer consultation time was recorded in patients with type 1 diabetes, higher glycated hemoglobin (HbA1c), use of insulin injections, and use of hypnotics/anxiolytics. The consultation time was longer in patients with HbA1c of ⩾7.0 to consultation. Older and female physicians provided longer consultation. Clinical consultation length in diabetes practice was associated with certain patient and physician characteristics. The findings can be used for making diabetes consultation more efficacious, which could eventually lead to the provision of the most appropriate consultation time for individual patients.

    2013-11-01

    This review evaluates three current theories--Standard Consolidation (Squire & Wixted, 2011), Overshadowing (Sutherland, Sparks, & Lehmann, 2010), and Multiple Trace-Transformation (Winocur, Moscovitch, & Bontempi, 2010)--in terms of their ability to account for the role of the hippocampus in recent and remote memory in animals. Evidence, based on consistent findings from tests of spatial memory and memory for acquired food preferences, favours the transformation account, but this conclusion is undermined by inconsistent results from studies that measured contextual fear memory, probably the most commonly used test of hippocampal involvement in anterograde and retrograde memory. Resolution of this issue may depend on exercising greater control over critical factors (e.g., contextual environment, amount of pre-exposure to the conditioning chamber, the number and distribution of foot-shocks) that can affect the representation of the memory shortly after learning and over the long-term. Research strategies aimed at characterizing the neural basis of long-term consolidation/transformation, as well as other outstanding issues are discussed.

    BACKGROUND: Stroke can affect a person\\'s ability to drive, an important means of transportation in the developed world. AIMS: To determine percentage of patients and factors associated with return to driving post-stroke in a service with emphasis on driver assessment. METHODS: Retrospective study of patients discharged from the Stroke Service of our 470-bed teaching hospital from 1998 to 2002. RESULTS: Of 72 drivers pre-stroke, 54% recalled a driving assessment and 68% returned to driving. Younger patients (58.6 +\\/- 12.0 vs. 66.5 +\\/- 10.5, p = 0.008) with lower Modified Rankin Score (median 1 vs. 2, p = 0.0001) and normal cognition (55 vs. 43%, p = 0.45) were more likely to resume driving. More patients who were assessed returned to driving than those who were not (74 vs. 61%, p = 0.31). CONCLUSIONS: A relatively high level of return to driving can be achieved post-stroke with a pro-active approach to driver assessment and rehabilitation. A structured assessment and referral programme should be offered where appropriate.

    In-hospital length of stay (LOS) has become a valuable measure of outcomes following any operation, which also directly impacts cost. The aim of this study was to identify the factors that affect LOS after colonic resection. A retrospective analysis was performed of adult patients who underwent colonic resection over an 8-y period at a tertiary institution. Data collected included demographics, American Society of Anesthesiologists (ASA) score, preoperative comorbidities and medications, operative management, postoperative morbidity and mortality, and LOS. Statistical analysis included descriptive statistics and multiple logistic regression to identify variables predictive of prolonged LOS. A total of 899 consecutive patients were identified. One hundred eighty-seven resections were performed urgently, and 712 were elective. Two-hundred forty-five cases were performed laparoscopically. Complications occurred in 205 cases (23%), and there were 32 deaths (4%). The median LOS was 7 d. Logistic analysis showed 15 variables to be predictive of prolonged LOS. These included advanced age, warfarin sodium use, ASA score >or=3, alcoholism, chronic obstructive pulmonary disease, end-stage renal disease, illicit drug use, total colectomy (versus segmental), open resections (versus laparoscopic), and postoperative complications. In addition, the presence of at least one postoperative complication was predictive of prolonged LOS (P = 0.0002, OR 2.4 95% CI 1.5-3.8). ASA score and the incidence of postoperative complications are the only significant categories of variables that predict prolonged LOS after colectomy. Laparoscopic approach and the extent of the resection are predictive as well.

  17. Microflora of Processed Cheese and the Factors Affecting It.

    The basic raw materials for the production of processed cheese are natural cheese which is treated by heat with the addition of emulsifying salts. From a point of view of the melting temperatures used (and the pH-value of the product), the course of processed cheese production can be considered "pasteurisation of cheese". During the melting process, the majority of vegetative forms of microorganisms, including bacteria of the family Enterobacteriaceae, are inactivated. The melting temperatures are not sufficient to kill the endospores, which survive the process but they are often weakened. From a microbiological point of view, the biggest contamination problem of processed cheese is caused by gram-positive spore-forming rod-shaped bacteria of the genera Bacillus, Geobacillus and Clostridium. Other factors affecting the shelf-life and quality of processed cheese are mainly the microbiological quality of the raw materials used, strict hygienic conditions during the manufacturing process as well as the type of packaging materials and storage conditions. The quality of processed cheese is not only dependent on the ingredients used but also on other parameters such as the value of water activity of the processed cheese, its pH-value, the presence of salts and emulsifying salts and the amount of fat in the product.

    Full Text Available smoking. Success of smoking cessation depends mainly on the balance between motivation and the degree of nicotine dependence. The objective of this study was to investigate factors affecting the motivation of smokers to stop smoking. Method: Data were collected from 139 smokers, aged 18-69 divided in two groups. Questionnaires were completed about the demographic data, smoking history, anthropometric characteristics, degree of nicotine dependence, motivation degree and alcohol consumption. Results: Body Mass Index was positively correlated with the dependence degree and heavy smoking, while those who were overweight in adolescence showed a lower degree of motivation for smoking cessation. Individuals with moderate or heavy alcohol consumption, those who smoked in their working environment and were heavier smokers needed greater motivation. The low degree of dependence was associated with a lower degree of motivation, while those who showed medium dependence were moderately motivated. Conclusions: Health care professionals should take into account all the above components with the aim of motivating smokers to stop smoking.

    Exclusive breastfeeding for the first 6 mo of life followed by optimal complementary feeding are critical public health measures for reducing and preventing morbidity and mortality in young children. Clinical factors, such as birth weight, prematurity, and illness, that affect the iron and zinc requirements of younger infants are discussed. Maternal diet and nutritional status do not have a strong effect on the mineral content of human milk, but physiologic changes in milk and the infants' status determine the dependence of the infant on complementary foods in addition to human milk to meet iron and zinc requirements after 6 mo. The nature of zinc absorption, which is suitably characterized by saturation response modeling, dictates that plant-based diets, which are low in zinc, are associated with low absolute daily absorbed zinc, which is inadequate to meet requirements. Foods with a higher zinc content, such as meats, are much more likely to be sufficient to meet dietary requirements. Current plant-based complementary feeding patterns for older fully breastfed infants in both developed and developing countries pose a risk of zinc deficiency. The strong rationale for the potential benefits of providing meat as an early complementary food, and the examples of successful intervention programs, provide potent incentives to pursue broader implementation programs, with concurrent rigorous evaluation of both efficacy and effectiveness.

    Wood of Chinese fir and poplar were liquefied in phenol at 150℃ and atmospheric pressure. The liquefied wood were reacted with formaldehyde to synthesize the liquefied wood-based resin. The factors affecting the resinification and the properties of new resin were investigated. The results show that the formaldehyde/liquefied wood molar ratio, reaction temperature, reaction time and sodium hydroxide/liquefied wood molar ratio have important influence on the resin characteristics. With the increase of formaldehyde/liquefied wood molar ratio, the yield of resin increases, and the free phenol content of resins decreases, showing that the resinification of liquefied wood is more complete at higher formaldehyde/liquefied wood molar ratios. The reaction temperature on the viscosity of the liquefied resin has considerable effect; the viscosity of resin increased with increasing reaction temperature,and the amount of liquefied poplar resin increased more quickly than that of liquefied Chinese fir resin. The resinification time also has obvious influence on the viscosity of resin; the viscosity of liquefied poplar resin is more sensitive to resinification time compared with that of liquefied Chinese fir. The amount of sodium hydroxide can improve the water miscibility of liquefied wood resin.The optimum sodium hydroxide/liquefied wood molar ratio for preparation of liquefied wood-based resins exceeds 0.4.

    Several important factors affecting the efficiency of Agrobacterium-mediated rice transformation were studied with several predominant commercial indica and japonica rice cultivars. As far as indica rice callus was concerned, CC medium was the best and the quality of callus was improved with the addition of 1.0 to 2.0 mg/L ABA. It decreased the percentage of browning calli and improved the callus growing state by addition of a certain amount of sorbitol to the subculture medium. NB medium was the best for callus initiation of japonica rice, but the improvement in the quality of callus of japonica subspecies was not obvious by adding ABA. During the period of subculture, to a certain degree, increasing the sucrose concentration could improve the proportion of hygromycin resistant calli. Furthermore, the transformation efficiency would be higher by applying selection pressure in the selection stage, removing selection pressure during the plantlet differentiation period and applying selection pressure again during seedling hardening period. Besides, suitable combination of plant hormones was beneficial for callus differentiation. An efficient Agrobacterium-mediated rice transformation system had been established for several rice cultivars and a lot of transgenic rice plants had been obtained.

    The factors affecting the ion beam implantation in silicon have been studied using boron, phosphorus, oxygen, and argon ions having energy range 0.5 ke V-200 ke V. It was found that the range of the ions in silicon increases with the increase of their energy and decreases with the increase of their masses. The ionization process is found to be the main process for causing damage in the silicon matrix whether it is produced by the accelerated ions or by the recoiled silicon atoms. The magnitude of ionization in silicon is found to be inversely proportional to the mass of ions. Ionization produced by ions or recoils shows different contributions to the damage depending on the mass of ions where the ions energy loss to ionization decreases from 70% to 23% as the mass is increased from 11 for boron (B) to 40 for argon (Ar). Its magnitude, as produced by ions, is found to decrease with the increase of their masses. Its value is observed to increase in a complementary way with the mass increase. Ions energy loss to...

    Factors affecting the efficient transformation of Colletotrichum species. Experimental Mycology, 18, 230-246. Twelve isolates representing four species of Colletotrichum were transformed either by enhanced protoplast, restriction enzyme-mediated integration (REMI), or electroporation-mediated protocols. The enhanced protoplast transformation protocol resulted in 100- and 50-fold increases in the transformation efficiencies of Colletotrichum lindemuthianum and C. magna , respectively. REMI transformation involved the use of Hin dIII and vector DNA linearized with HindIII to increase the number of integration events and potential gene disruptions in the fungal genome. Combining the enhanced protoplast and the REMI protocols resulted in a 22-fold increase in the number of hygromycin/nystatin-resistant mutants in C. lindemuthianum . Electroporation-mediated transformation was performed on mycelial fragments and spores of four Colletotrichum species, resulting in efficiencies of up to 1000 transformants/μg DNA. The pHA1.3 vector which confers hygromycin resistance contains telomeric sequences from Fusarium oxysporum , transforms by autonomous replication and genomic integration, and was essential for elevated transformation efficiencies of 100 to 10,000 transformants/μg DNA. Modifications of pHA1.3 occurred during bacterial amplification and post fungal transformation resulting in plasmids capable of significantly elevated transformation efficiencies in C. lindemuthianum.

    The study aimed to recognize the personality factors of a predisposition to seasonal mood fluctuations in a non-clinical sample. A group of 101 subjects (57 women, 44 men; mean age 26.4 ± 6.5 years) completed a battery of tests comprising a Seasonal Pattern Assessment Questionnaire (SPAQ), Chronotype Questionnaire (ChQ), a NEO-Five Factor Inventory and a Coping Inventory for Stressful Situations (CISS). A smaller sample (n = 44) completed a Winter Blues Scale (WBS). Women scored significantly higher than men in seasonality (p = 0.014), neuroticism (p = 0.049), agreeableness (p = 0.010), and avoidance-oriented coping style (p = 0.041). Subjects with seasonal affective disorder (SAD) (n = 41) or sub-SAD (n = 33), as diagnosed with SPAQ, exhibited higher levels of neuroticism (p = 0.017) and openness (p = 0.016) in comparison to non-SAD individuals. The latter declared a less frequent avoidance coping style. Both measures of seasonality, i.e. the SPAQ Global Seasonality Score and WBS, correlated significantly (r = 0.28 and 0.44, respectively) with the subjective amplitude of the circadian rhythm, as described with the "distinctness" scale of ChQ. Female gender, neuroticism and openness were confirmed as factors linked to seasonal mood variability. Additionally, the study revealed an association between susceptibility to mild winter depression and an avoidance-oriented coping style. The avoidance coping style was correlated positively with all the aspects of seasonality described by SPAQ (correlation coefficients from 0.21 to 0.34). Both sub-types of avoidance-oriented style, i.e. distraction and social diversion, were associated with marked subjective seasonal changes in sleep length, mood and the energy level. While the subjective amplitude of circadian rhythm proved to be connected with seasonality, the subjective acrophase of the rhythm (morningness-eveningness preference) did not. It may be hypothesized that sensitivity

    With advances in robot technology, interest in robotic e-learning systems has increased. In some laboratories, experiments are being conducted with humanoid robots as artificial tutors because of their likeness to humans, the rich possibilities of using this type of media, and the multimodal interaction capabilities of these robots. The robot-assisted learning system, a special type of e-learning system, aims to increase the learner's concentration, pleasure, and learning performance dramatically. However, very few empirical studies have examined the effect on learning performance of incorporating humanoid robot technology into e-learning systems or people's willingness to accept or adopt robot-assisted learning systems. In particular, human likeness, the essential characteristic of humanoid robots as compared with conventional e-learning systems, has not been discussed in a theoretical context. Hence, the purpose of this study is to propose a theoretical model to explain the process of adoption of robot-assisted learning systems. In the proposed model, human likeness is conceptualized as a combination of media richness, multimodal interaction capabilities, and para-social relationships; these factors are considered as possible determinants of the degree to which human cognition and affection are related to the adoption of robot-assisted learning systems.

    Trophoblastic cell fusion is one essential step of the human trophoblast differentiation pathway and is a multifactorial and dynamic process finely regulated and still poorly known. Disturbances of syncytiotrophoblast formation are observed in numerous pathological clinical conditions such as preeclampsia, intrauterine growth retardation and trisomy 21. In this review, we summarize current knowledge of the different membrane proteins directly involved in trophoblastic cell fusion, which we identified by using the physiological model of primary culture of villous trophoblastic cells. Connexin 43 and gap junctional intercellular communication point to the role of molecular exchanges through connexin channels preceding membrane fusion. Zona occludens-1, which can interact with connexin 43, is also directly involved in trophoblast fusion. The recently identified fusogenic membrane retroviral envelop glycoproteins syncytin 1 (encoded by the HERV-W gene) and syncytin 2 (encoded by the FRD gene) and their receptors are major factors involved in human placental development . We describe the increasing number of factors promoting or inhibiting trophoblast fusion and differentiation and emphasize the role of human chorionic gonadotropin (hCG) and its receptor. Indeed, in trisomy 21 the dynamic process leading to membrane fusion is impaired due to an abnormal hCG signaling. This abnormal trophoblast fusion and differentiation in trisomy 21-affected placenta is reversible in vitro. Trisomy 21 trophoblastic cell culture may therefore be useful to identify the possible large number of prerequisite factors involved in trophoblast fusion, the limiting step of trophoblast differentiation.

    Neural progenitor cell (NPC) transplantation offers great potential to treat spinal cord injury (SCI). NPCs may replace lost neurons or oligodendrocytes and act as a source of neurotrophic factors to support survival of remaining cells. However, their efficiency was limited by poor survival after transplantation, and they tended more to differentiate into astrocytes, but not neurons and oligodendrocytes. This study investigated whether activated microglia is a factor that contributes to this phenomenon. Organotypic spinal cord slice (SCS) culture was used to mimic the local environment after SCI, and NPCs were co-cultured with them to share the culture medium. After specific depletion of microglia in the SCSs with clodronate loaded liposome, the apoptotic rate of NPCs decreased, more NPCs differentiated into neurons, and glial differentiation was impaired. This suggested that microglia may impair NPC survival, and neuronal differentiation, but improve astrocyte differentiation. In NPC transplantation strategy for SCI, microglia would be manipulated to improve the survival and neuronal differentiation of NPCs.

    A series of 4 experiments was conducted to examine factors affecting the survival of frozen-thawed 2-cell mouse embryos. Rapid addition of 1.5 M-DMSO (20 min equilibration at 25 degrees C) and immediate, rapid removal using 0.5 M-sucrose did not alter the frequency (mean +/- s.e.m.) of blastocyst development in vitro when compared to untreated controls (90.5 +/- 2.7% vs 95.3 +/- 2.8%). There was an interaction between the temperature at which slow cooling was terminated and thawing rate. Termination of slow cooling (-0.3 degrees C/min) at -40 degrees C with subsequent rapid thawing (approximately 1500 degrees C/min) resulted in a lower frequency of blastocyst development than did termination of slow cooling at -80 degrees C with subsequent slow thawing (+8 degrees C/min) (36.8 +/- 5.6% vs 63.9 +/- 5.7%). When slow cooling was terminated between -40 and -60 degrees C, higher survival rates were achieved with rapid thawing. When slow cooling was terminated below -60 degrees C, higher survival rates were obtained with slow thawing rates. In these comparisons absolute survival rates were highest among embryos cooled below -60 degrees C and thawed slowly. However, when slow cooling was terminated at -32 degrees C, with subsequent rapid warming, survival rates were not different from those obtained when embryos were cooled to -80 degrees C and thawed slowly (52.4 +/- 9.5%, 59.5 +/- 8.6%). These results suggest that optimal cryosurvival rates may be obtained from 2-cell mouse embryos by a rapid or slow thawing procedure, as has been found for mouse preimplantation embryos at later stages.(ABSTRACT TRUNCATED AT 250 WORDS)

    Difficulties in the detection of pancreatic damage result in morbidity and mortality in cases of pancreatic trauma. This study was performed to determine factors affecting morbidity and mortality in pancreatic trauma. The records of 33 patients who underwent surgery for pancreatic trauma between January 2004 and December 2013 were analyzed retrospectively. The types of injury were penetrating injury and blunt abdominal trauma in 75.8 and 24.2 % of all cases, respectively. Injuries were classified as stage 1 in 6 cases (18.2 %), stage 2 in 18 cases (54.5 %), stage 3 in 5 cases (15.2 %), and stage 4 in 4 cases (12.1 %). The average injury severity scale (ISS) value was 25.70 ± 9:33. Six patients (18.2 %) had isolated pancreatic injury, 27 (81.2 %) had additional intraabdominal organ injuries and 10 patients (30.3 %) had extraabdominal organ injuries. The mean length of hospital stay was 13.24 ± 9 days. Various complications were observed in eight patients (24.2 %) and mortality occurred in three (9.1 %). Complications were more frequent in patients with high pancreatic damage scores (p = 0.024), additional organ injuries (p = 0.05), and blunt trauma (p = 0.026). Pancreatic injury score was associated with morbidity, while the presence of major vascular injury was associated with mortality. Complications were significantly more common in injuries with higher pancreatic damage scores, additional organ injuries, and blunt abdominal trauma. Pancreatic injury score was associated with morbidity, while the presence of major vascular injury was associated with mortality.

    Full Text Available Necrotizing enterocolitis (NEC is the most devastating intestinal disease affecting preterm infants. In addition to being associated with short term mortality and morbidity, survivors are left with significant long term sequelae. The cost of caring for these infants is high. Epidemiologic evidence suggests that use of antibiotics and type of feeding may cause an intestinal dysbiosis important in the pathogenesis of NEC, but the contribution of specific infectious agents is poorly understood. Fecal samples from preterm infants ≤ 32 weeks gestation were analyzed using 16S rRNA based methods at 2, 1, and 0 weeks, prior to diagnosis of NEC in 18 NEC cases and 35 controls. Environmental factors such as antibiotic usage, feeding type (human milk versus formula and location of neonatal intensive care unit (NICU were also evaluated. Microbiota composition differed between the three neonatal units where we observed differences in antibiotic usage. In NEC cases we observed a higher proportion of Proteobacteria (61% two weeks and of Actinobacteria (3% 1 week before diagnosis of NEC compared to controls (19% and 0.4%, respectively and lower numbers of Bifidobacteria counts and Bacteroidetes proportions in the weeks before NEC diagnosis. In the first fecal samples obtained during week one of life we detected a novel signature sequence, distinct from but matching closest to Klebsiella pneumoniae, that was strongly associated with NEC development later in life. Infants who develop NEC exhibit a different pattern of microbial colonization compared to controls. Antibiotic usage correlated with these differences and combined with type of feeding likely plays a critical role in the development of NEC.

    The international standard IEC 62220-1 about DQE measurement of digital X-ray equipment was published in 2003, but mammography systems aren"t applied to this IEC standard because the factor affect measurement is complicated. Especially, the influence to the pre-sampling MTF by edge method when X-ray beam is oblique to detector. The influence of nonuniformity of x-ray intensity by the heel effect on digital Wiener spectrum (WS) doesn"t become clear. A 0.1mm-thick tungsten edge was imaged in the position where X-ray beam was perpendicular to detector plane and in 6cm from chest wall, respectively. And the pre-sampling MTFs were obtained from these edge images. The calculation area of the digital WS within irradiation area was moved in parallel direction to X-ray tube axis, and the digital WS were calculated. The pre-sampling MTFs and the digital WS are calculated by the method based on the IEC proposal. We used MAMMOMAT3000(SIEMENS), MGU-100B(TOSHIBA), M-IV(LORAD) and Senographe DMR+(GE) as X-ray generator. Images were obtained by FCR PROFECT CS (Fujifilm medical). In all equipments and both arrangement directions of the edge test device, pre-sampling MTFs are almost the same, even if the arrangement places of the edge test device varied. In all equipments, when the calculation area was moved about 10cm, the digital WS of the anode side was higher 7.2-17.9% than those of the cathode side. It was found that the dose of anode side was lower about 20% than cathode side from the profile of an exposure image. We think that digital WS modified the nonuniformity of the dose by the heel effect is obtained by multiplying the digital WS by the compensation coefficient obtained by the dose profile, in low spatial frequency.

    Full Text Available The efficiency of the pellet can be translated by the quality of the pellet which is defined as the proportion of intact pellets that come to feeders for chickens, i.e., its resistance to breakage between the feed mill and farms. The use of diets with a higher percentage of intact pellets results in better performance of birds when compared with the feed rations. The main factors that affect pellet quality are: characteristics of pelleting, the feed composition, particle size, pelleting temperature, moisture and steam injection. From a nutritional standpoint, one can consider that the smaller the particle size of food increased their contact with the digestive juices, which aids digestion and absorption of nutrients. However, finely ground lead to less stimulation and growth of intestinal ephitellium. But from the standpoint of production of feed, the larger the particle size of ingredients largest economy with energy and greater efficiency (tons / hour milling. Because of this, it is suggested that the particle sizes used vary between 500 and 700 ìm to not to cause loss of performance of the birds, nor the income from the factory. Increased energy, through the addition of oils and fats, have much influence on performance parameters of broilers and the quality of the pellet produced. The presence of oils and / or fat, depending on the amount, on its hydrophoby characteristic, causing damage to the particles aggregation acting as a lubricant between food particles and the matrix of pelleting, decreasing the pelleting pressure and its gelatinization, resulting into poor quality pellets.

    This paper investigates the nutritional status of a randomly selected cohort of school children and the factors affecting it. This random survey was conducted in the state of Selangor, involving 1,405 primary students (aged 9-10 years from 54 national primary schools). Physical examination was carried out on all the students. Information on the students was also obtained from the parents. Blood samples were taken by using the finger pricking technique. Body mass index (BMI) was used as a measure of physical growth. The students were mainly from urban areas (82.9%). The mean age was 9.71 years and a higher proportion was females (51%). Malays constituted 83.6%, Indians 11.6% and Chinese 4.2% of the study population. The mean weight and height were 32.30 kg and 135.18 cm respectively. The mean BMI was 17.42 kg/m2, with 1.2% of the students underweight, 76.3% normal BMI, 16.3% overweight and 6.3% were obese. Nutritional status was significantly related to blood pressure, history of breast feeding, eating fast food, taking canned/bottled drinks, income and educational level of parents. Significant differences in nutritional status between sexes and locations (rural/urban) were also found. The prevalence of overweight and obese children was of concern. There is thus an urgent need for the School Health Program to periodically monitor the school children's eating habits and physical growth. Appropriate counselling on nutritional intake and physical activities should be given not only to schoolchildren but also to their teachers and parents or caregivers.

    To identify the risk factors associated with fluoroquinolone resistance in patients undergoing cataract surgery. A total of 1,125 patients (1,125 eyes) who underwent cataract surgery at Veterans Health Service Medical Center from May 2011 to July 2012 were enrolled in this study. Conjunctival cultures were obtained from the patients on the day of surgery before instillation of any ophthalmic solutions. The medical records of patients with positive coagulase negative staphylococcus (CNS) and Staphylococcus aureus (S. aureus) cultures were reviewed to determine factors associated with fluoroquinolone resistance. Of 734 CNS and S. aureus cultures, 175 (23.8%) were resistant to ciprofloxacin, levofloxacin, gatifloxacin, or moxifloxacin. Use of fluoroquinolone within 3 months and within 1 year before surgery, topical antibiotic use other than fluoroquinolone, systemic antibiotic use, recent hospitalization, ocular surgery, intravitreal injection and use of eyedrops containing benzalkonium chloride were significantly more frequent in resistant isolates than in susceptible isolates. In multivariable logistic regression analysis, ocular surgery (odds ratio [OR], 8.457), recent hospitalization (OR, 6.646) and use of fluoroquinolone within 3 months before surgery (OR, 4.918) were significant predictors of fluoroquinolone resistance, along with intravitreal injection (OR, 2.976), systemic antibiotic use (OR, 2.665), use of eyedrops containing benzalkonium chloride (OR, 2.323), use of fluoroquinolone within 1 year before surgery (OR, 1.943) and topical antibiotic use other than fluoroquinolone (OR, 1.673). Recent topical fluoroquinolone use, hospitalization and ocular surgery were significantly associated with fluoroquinolone resistance in CNS and S. aureus isolates from ocular culture.

    Full Text Available Within certain cultural and social limits, some behaviours linked to the use of new technology, gaming, physical exercise or work are useful practices with a positive social value for both individuals and society. As these practices are commonly and socially accepted, the trend is to underestimate the risks and not to perceive them as deviances even when they start to be compulsive. This paper focuses on the concept of new non-substance addictions and on how some social factors influence, on the one side, this new interaction between man and technology and, on the other side, social relationships in the electronic environment.

    Full Text Available Introduction The longevity is normally defined as the length of its productive life in the flock, which is the amount of time an animal spends producing (1. Longevity reflects the ability of ewe to avoid being culled for low production, low fertility, illness and influences the number and cost of replacements required to maintain the flock size. The benefit of increasing longevity are increased average age of the flock, having more ewes available for sale at the end of their four parity, having more ewe lambs to sell, and higher productivity from a slightly older flock age profile (2. Sheep population of Khorasan province (10. In sheep production, longevity has an important influence on the economic returns. Reliable estimates of non genetic effects of longevity are needed to aid establishing an efficient strategy for improving ewe productivity. Thus, the objective of this study was the factors affecting on longevity in Northern Khorasan Kordish sheep. We want to determine effect of environmental and non-genetic factors on longevity. Material and Methods In order to investigate on factors affecting longevity trait in Northen Khorasan Kordish sheep, records of 7469 sheep (187 sire and 2258 dam between 1990 to 2012 that were collected by breeding station of Hossein Abad in Shirvan (This city is located in the north of Mashhad were used. Flock has been kept under village system. Breeding ewes were identified in the data set as those that lambed at 2 year of age and culled at 6 to 7 year of age duo to oldness. Ram kept until a male offspring was available for replacement. In this study longevity was defined as the age of a ewe (in day when it leaves the flock. Ewes were generally removed from the flock due to poor production, low fertility, death and illness. Ewes were identified as being removed from the flock if a lambing record was present at n year of age but not at n+1 years of age. All females were culled before reaching 7 years of age

    The aim of this study was to determine epidemiologic characters of patients with candidemia and to evaluate risk factors that can affect mortality rates among these patients. Patients admitted to the İstanbul Medeniyet University Göztepe Training Hospital between 2009 and 2011 who had a positive blood culture for Candida spp. during hospitalization were studied retrospectively for demographic characteristics and risk factors. Statistical comparisons were estimated with the Stata 12 package. Independent variables associated with mortality were estimated by Cox regression analyses. A total of 89 patients were identified with a positive blood culture. Of the isolates, 72% (64/89) were C. albicans and 10% (9/89) were non-albicans Candida, while 18% (16/89) were unidentified. C. parapsilosis was the most frequently isolated species among non-albicans Candida. The crude mortality rate among candidemia cases was 30% (27/89). By univariate analysis, being in the ICU and age (≥50 or ≥60) were found to be statistically significant, whereas by multivariate analysis only age of ≥50 years was independently more associated with mortality (OR, 2.7; CI, 1.05-6.73). Candidemia is associated with high mortality rates. Patients older than 50 years are found to be at considerable risk in terms of adverse outcomes.

    Research is a global enterprise requiring participation of both genders for generalizable knowledge; advancement of science and evidence based medical treatment. Participation of women in research is necessary to reduce the current bias that most empirical evidence is obtained from studies with men to inform health care and related policy interventions. Various factors are assumed to limit autonomy amongst the Yoruba women of western Nigeria. This paper seeks to explore the experience and understanding of autonomy by the Yoruba women in relation to research participation. Focus is on factors that affect women's autonomous decision making in research participation. An exploratory qualitative approach comprising four focus group discussions, 42 in-depth interviews and 14 key informant interviews was used. The study permits a significant amount of triangulation, as opinions of husbands and religious leaders are also explored. Interviews and discussions were audiotaped and transcribed verbatim. Content analysis was employed for data analysis. Findings show that concepts of autonomy varied amongst the Yoruba women. Patriarchy, religion and culture are conceived to have negative impact on the autonomy of women in respect to research participation. Among the important findings are: 1) male dominance is strongly emphasized by religious leaders who should teach equality, 2) while men feel that by making decisions for women, they are protecting them, the women on the other hand see this protection as a way of limiting their autonomy. We recommend further studies to develop culturally appropriate and workable recruitment methods to increase women's participation in research.

    The results of clinical trials using mesenchymal stem cells (MSCs) are controversial due to the heterogeneity of human MSCs and differences in culture conditions. In this regard, it is important to identify gene expression patterns according to culture conditions, and to determine how the cells are expanded and when they should be clinically used. In the current study, stemness gene expression was investigated in adipose tissue-derived MSCs (AT-MSCs) harvested following culture at different densities. AT-MSCs were plated at a density of 200 or 5,000 cells/cm(2). After 7 days of culture, stemness gene expression was examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis. The proliferation rate of AT-MSCs harvested at a low density (~50% confluent) was higher than that of AT-MSCs harvested at a high density (~90% confluent). Although there were differences in the expression levels of stemness gene, such as octamer-binding transcription factor 4, nanog homeobox (Nanog), SRY-box 2, Kruppel like factor 4, v-myc avian myelocytomatosis viral oncogene homolog (c-Myc), and lin-28 homolog A, in the AT-MSCs obtained from different donors, RT-qPCR analysis demonstrated differential gene expression patterns according to the cell culture density. Expression levels of stemness genes, particularly Nanog and c-Myc, were upregulated in AT-MSCs harvested at a low density (~50% confluent) in comparison to AT-MSCs from the same donor harvested at a high density (~90% confluent). These results imply that culture conditions, such as the cell density at harvesting, modulate the stemness gene expression and proliferation of MSCs.

    Increasing evidence supports the contribution of both biological and cultural factors to visuospatial processing. The present study adds to the literature by exploring the interplay of perceptual and linguistic mechanisms in determining visuospatial asymmetries in adults (Experiment 1) and children (Experiment 2). In particular, pre-schoolers (3 and 5 year-olds), school-aged children (8 year-old), and adult participants were required to bisect different types of stimuli, that is, lines, words, and figure strings. In accordance with the literature, results yielded a leftward bias for lines and words and a rightward bias for figure strings, in adult participants. More critically, different biases were found for lines, words, and figure strings in children as a function of age, reflecting the impact of both cultural and biological factors on the processing of different visuospatial materials. Specifically, an adult-like pattern of results emerged only in the older group of children (8 year-old), but not in pre-schoolers. Results are discussed in terms of literacy, reading habits exposure, and biological maturation.

    Consideration of patient autonomy is an essential element in individualized, patient-centered, ethical care. Internal and external factors associated with patient autonomy are related to culture and it is not clear what they are in Iran. The aim of this study was to explore contextual factors affecting the autonomy of patients in Iranian hospitals. This was a qualitative study using conventional content analysis methods. Thirty-four participants (23 patients, 9 nurses, and 2 doctors) from three Iranian teaching hospitals, selected using purposive sampling, participated in semi-structured interviews. Unstructured observation and filed notes were other methods for data collection. The data were subjected to qualitative content analysis and analyzed using the MAXQDA-10 software. Five categories and sixteen subcategories were identified. The five main categories related to patient autonomy were: Intrapersonal factors, physical health status, supportive family and friends, communication style, and organizational constraints. In summary, this study uncovered contextual factors that the care team, managers, and planners in the health field should target in order to improve patient autonomy in Iranian hospitals.

    Though the cultural factors that may contribute to the diabetes epidemic in First Nations are frequently discussed, little is known about the factors that may help prevent it. In this ethnonursing study, we explore the cultural factors that help maintain health behaviours in Algonquin women who had received a diagnosis of gestational diabetes 2 to 10 years before this study. The data were collected in two Algonquin communities through semi-structured interviews with key informants (n = 7) and general informants (n = 8) and through cultural immersion, with detailed observations being recorded into logbooks. The cultural factors that are likely to affect the prevention of diabetes are the importance of family and social ties, the possibility of preserving cultural values, the opportunity to learn behaviours through educational resources adapted to needs and culture, the chance of saving money through better diet and access to blood sugar data as a means of control. In the long term, these cultural factors could influence health behaviours and thus help prevent type 2 diabetes.

    Full Text Available Objectives: Weaning failure rate was higher in patients with chronic obstructive pulmonary disease (COPD and many factors affect it. The aim of this study was to investigate the factors affecting the success of weaning in COPD patients receiving invasive mechanical ventilation (IMV.Materials and methods: Totally 43 COPD patients who received IMV in intensive care unit were included. Clinical and laboratory results and Acute Physiology Assessment and Chronic Health Evaluation (APACHE II scores were recorded and affecting factors on weaning success were investigated.Results: In 43 patients, 25 had successful weaning (58.1%. Patients with high APACHE II score prior to intubation was found as associated with weaning failure. High Glasgow coma scale (GCS scores before entubation and weaning are associated with weaning success. Pre-weaning anxiety, positive endotracheal aspirate culture, pulmonary arterial pressure value, enteral feeding, pre-weaning tachycardia, pre-weaning cuff leaking and FiO2 values were found to be associated with weaning failure. Pre-weaning cortisol levels were associated with weaning success. In successful weaning group, measured NIF and VT in spontaneous mode were found as higher and f/VT ratio was lower compared with unsuccessful group. T-tube during the 15th and 30th minutes of the symptoms of fatigue (sweating assets were associated with weaning failure. IMV duration and longer extubation duration of weaning, and more number of t-tube insertion attempts were found as associated with failure of weaning.Conclusions: Infection in patients with COPD, the presence of anxiety, and hemodynamic and respiratory instability significantly increases the weaning failure.
