We examined the effect of type D personality on self-care behaviors and self-efficacy among Chinese HF patients. Methods A cross-sectional study with a convenience sample was conducted. All participants completed the questionnaires of the self-care of HF index (V6) and type D personality scale. Demographic and clinical variables were obtained from medical records and patient interviews. The me- thods used for data analysis included descriptive analysis, independent-sample t-test, Z2 test, and multiple linear regression. Results A total of 127 HF patients were included and 61.4% of them were male. The average age for this study sample was 64.9± 12.34 years. The majority of the participants were in a New York Heart Association class III or IV (87%), and the average length of living with HF was 38.24 ± 41.1 months. A total of 33.1% of the participants were identified as having type D personality. No significant differences were determined in the demographic and clinical variables between type D and non-type D patients, except for the mean age and the length of living with HF. Type D patients were younger and had a shorter time of living with HF than their non-type D counterparts. Multiple regression demonstrated significant associations between type D personality and self-care maintenance and self-efficacy after adjusting the demographic and clinical factors. However, type D personality was not significantly associated with self-care management behaviors. Conclusions Type D personality was negatively related to self-care maintenance and self-efficacy in Chinese HF patients. Future study is warranted to develop a tailored intervention to improve engagement in self-care behaviors in HF patients with type D personality.展开更多

How- ever, most of these models have been established on lower animals, such as rodents, and involve only a single administration of a noxious stimulus. In this study, an inflammatory soup (10 μL), consisting of prostaglandin E2 (0.2 mM), serotonin (2 mM), bradykinin (2 raM) and histamine (2 raM), was injected into the dura mater of conscious rhesus monkeys through an indwelling catheter. The infusion started on day 8 and was repeated every 3 days, for a total of six administrations, to induce neurogenic inflammation. We performed behavioral assessments and measured the expression of the oncogene c-fos, neuronal nitric oxide synthase (nNOS) and calcitonin gene related peptide (CGRP) ill the trigeminal system and in multiple brain regions involved in pain processing by immunohistochemical staining. Compared with monkeys in the control group, three of the four animals in the inflammatory soup group displayed decreased motor behaviors, and two showed increased ipsilateral nose and mouth secretions during the stimulus period. Higher expression levels of c-fos, nNOS and CGRP were found in various brain areas of experimental animals compared with controls, including the trigeminal nucleus caudalis, thalamus, hypothalamus, midbrain, pons and other areas involved in pain perception. These results suggest that repeated inflammatory soup stimulation of the dura activates the trigeminovascular system and produces migraine-like pathological changes and abnormal behaviors in conscious rhesus monkeys.展开更多

However, considering m ost of the communications in opportunistic networks are caused by forwarding operations, there is no need to establish the complete mutual authentications for each conversation. Accordingly, a novel trust management scheme is presented based on the information of behavior feedback, in order to complement the insufficiency of identity authentications. By utilizing the certificate chains based on social attributes, the mobile nodes build the local certificate graphs gradually to realize the web of "Identity Trust" relationship. Meanwhile, the successors generate Verified Feedback Packets for each positive behavior, and consequently the "Behavior Trust" relationship is formed for slow-moving nodes. Simulation result shows that, by implementing our trust scheme, the d elivery probability and trust reconstruction ratio can be effectively improved when there are large numbers of compromised nodes, and it means that our trust management scheme can efficiently explore and filter the trust nodes for secure forwarding in opportunistic networks.展开更多

This study hypothesized that the development of a feeling of high involvement among employees of organizations implementing the Environmental Management System (EMS) could result in the spillover phenomena of other environmentally responsible behavior in different domains such as, consumer preferences for environment-friendly products. The study also confirms the effects of environmental attitude (EA) and concrete knowledge (CK) as a mediator; acting not only as an axis to the spillover phenomenon but is also found to be the crucial factor in determining the strength of the whole spillover process.展开更多

An accurate diagnosis is necessary for the optimal management of perianal lesions. Treatment of perianal Crohn's disease includes medical and/or surgical options. Recent discoveries in the pathogenesis of this disease have led to advances in medical and surgical therapy with good results. Perianal lesions in Crohn's disease remain a challenging aspect for both gastroenterologists and surgeons and lead to a greatly impaired quality of life for all patients affected by this disease. A multidisciplinary approach is mandatory to obtain the best results.展开更多

Surveying Italian professionals, we do not only reveal typical gender differences but also detect divergence to their German counterparts. While disclosing Italian professionals' overly positive self-assessment in general, we find evidence for male overconfidence in particular--though without being accompanied by excessive control illusion of the own information level. Asset managers' risk taking reveals further differences: Italian female professionals do not only assess themselves as more risk averse than their male colleagues, they also prefer a more passive portfolio management compared to the level they are allowed to. Moreover, in a tournament scenario near the end of the investment period female asset managers do not try to become the ultimate top performer when they have outperformed their peer group so far. However, in case of underperformance, the risk of deviating from the benchmark makes especially female professionals willing to seize a chance of catching up. Overall, compared to their German counterparts, we find Italian asset managers to be slightly more risk averse. Matching bounded former results on Italian mutual funds, we discuss interdependencies as well as impact of our findings at the individual asset managers' level on trading activity, management style and performance.展开更多

Deliberate manipulation of financial numbers by a company is rarely a one-off event; it is more a culture of widespread earnings management that permeates an organization and eventually leads to a full-blown accounting fraud. This paper looks at earnings management practices in Indian companies and examines the extent of earnings management prevalent across firms of varying market capitalization. The present study examines 130 listed Indian companies during the period of 2013-2015. The findings of this study provide a measure of the quality of financial reporting in India. Modified Jones model (1995) is used to estimate discretionary accruals (DA), which is considered as a proxy for earnings management. The average DA is estimated at 5.6% of the total assets of the firms, which is comparable to the estimates in other parts of the world (about 1%-5% of total assets). A sector-specific analysis reveals presence of higher earnings manipulation in the consumer durable and energy sectors. Large cap companies are found to show a lower level of eamings management as compared to the small-cap firms. The study also finds a dip in the magnitude of DA in 2015, which is the first year of application of the new Companies Act 2013. Subsequent years will reveal the true success of the new Act in enforcing a stricter regime of corporate governance and greater accountability of corporate boards and audit committees. International studies point towards a high degree of correlation between effective audit committees and lower levels of earnings management in companies. Further work in this field from an Indian context will help identify factors that have a constraining effect on earnings management, and ultimately help preserve the sanctity of reported financial numbers.展开更多

Tourism industry today is one of the highest revenue generating industry and strategic approach for sustainable development of this industry hosts benefits not only for the tourism related stakeholders but also the community and economy on the whole. Oman is one of the most preferred destinations for the tourists especially after the declaration of Muscat, Arab tourism Capital for 2012. Thus to materialize this honor and position, the scientific study and analysis of tourist behavior will help to predict the future trend of tourism and will give direction for effort investment. This work presents a novel strategy to identify, analyze and highlights the main tourist behavioral factors that could increase tourists' loyalty to a specific destination or agency. The analytical TSS (tourism support system) will also classify customers into two categories--first category will be classified as "LT (loyal tourists)" and second category as "NLT (non-loyal tourists)". Dataset is collected from a tourism business organization. Twenty-four attributes and 545 instances were collected and were analyzed by algorithms like logistics, forest of random trees, naive Bayes, J48 and Id3. The explanatory variables were defined, and some transformations were done to identify the response variable. Entropy was used and adapted in order to find the response variable from the explanatory variables. The results obtained from this work confirm that the generated rules can be used for future prediction and tourism business can be improved and efforts can be directed in right place for the right consumer resulting in high return on investment.展开更多

Using 142 firms listed in the Shenzhen Stock Exchange (SZSE), which was collected from the Guotaian Research Service Center (GTA-RSC) databases, this study uses two proxies to measure firm performance and three proxies to measure managerial entrenchment. The two proxies for firm performance are Tobins' Q and return on assets (ROA), and the three proxies for managerial entrenchment are entrenchment 1, entrenchment 2, and entrenchment 3. These three entrenchment proxies are derived from the principal component analysis (PCA). Though previous studies of managerial entrenchment and firm performance variables suffer from endogeneity, with respect to the corporate governance it is unclear as to which variables are endogenous and which are exogenous. This study confirms that the data are linear and no endogeneity issue should be address in this study, but only heteroskedasticity, non-normality for Tobins' Q are a problem, therefore, the regression method employed for Tobins' Q is the generalised least square (GLS) and the ordinary least square (OLS) between estimators for ROA. The regression result for Tobins' Q reveals that managerial entrenchment is negatively impact on firm performance. The results are in contradiction to the stewardship theory for new firms whereas the managerial entrenchment for new firms is positive. Furthermore, only one entrenchment proxy yields a significant coefficient. In conclusion, the negative results of entrenchment proxies were caused by the different institutional structures and legal systems which are the Chinese corporations that are still largely owned and controlled by a state and hence the centralised state controlled was responsible for all managerial actions.展开更多

Methods: Electronic databases including the Cochrane library, PubMed, EMBASE, the Web of Science, CBM, Wanfang, VIP and CNKI were searched from inception to October 2017 to collect literature on the correlation between time manage-ment disposition and ability confidence of Chinese nursing students. The studies were examined according to the inclusion and exclusion criteria. After extracting data and evaluating the quality of the included studies. Meta-analysis was carried out using Stata 12.0 software. Results: A total of 7 articles with 1632 nursing students were included, and the quality of the literature was at medium level. Meta-analysis shown the total score of time management disposition of Chinese nursing students and its three dimensions were related to ability confidence. The summary correlation coefficient between time management disposition and ability confidence was 0.52 (0.43 to 0.59) ; There is a weak correlation between time value and ability confidence (r, 0.33; 95% CI, 0.25 to 0.39); There was a moderate level of correlation between time control and ability confidence (r, 0.49; 95% CI, 0.43 to 0.54); There was a moderate level of correlation between time efficacy and ability confidence (0.47, 0.41, 0.53).And the relevance of nursing time management disposition and behavioral confidence varies with the nursing student's area, nursing student's diploma, measurement tools and sample size. Conclusion: The time man- agement disposition of Chinese nursing students is moderately related to ability confidence. When there are different in nursing students in the area, nursing diploma, measurement tools and sample size, the relevance is very different. The time management disposition of Chinese nursing students and their ability confidence are mutually reinforcing, and the time management disposition and their ability confidence should be further strengthened in the future.展开更多

If it is left untreated, it can eventually result in end stage renal failure and necessitate dialysis or kidney transplantation. There is no cure for CKD; instead a great deal of self management over time is essential. The purpose is to evaluate self management behaviour of patients at different stages of CKD. A total of 300 CKD patients were recruited in this cross sectional study from March to July 2015 at nephrology clinic of a tertiary care setting using convenience sampling. Self management behaviour score was determined using in Partners in Health scale and was then compared at different stages of CKD. Demographic and clinical factors contributing to self management behaviour were determined. Results: There was a significant difference in age (p 〈 0.001), gender (p 〈 0.001), education level (p 〈 0.001), marital status (p 〈 0.001), duration of illness (p 〈 0.001) and number of co-morbidities (p 〈 0.001) among CKD stages. A significant difference in self management behaviour mean score was found among CKD stages (p 〈 0.001). Post hoc analysis showed self management behaviour mean score for Stage Ⅰ (mean ± SD: 77.81 ± 9.41) was significantly higher than Stage Ⅳ (mean ± SD: 70.53 ± 13.91) and Stage Ⅴ (mean ± SD: 69.54 ± 12.31). Self management behaviour mean score for Stage Ⅱ (mean ± SD: 78.46 ± 10.01) was significantly higher than Stage Ⅳ and Stage Ⅴ. Multiple linear regression revealed education level (p 〈 0.001) and number of co-morbidities (p = 0.01) as significant predictors of self management behaviour. It can be concluded that special attention should be focused on patients at late stage of CKD, especially those with diabetic nephropathy; low education level and multiple co-morbidities to improve self management behaviour.展开更多

文摘Several animal models of migraine have been established, and those based on trigeminovascular system activation are widely accepted. How- ever, most of these models have been established on lower animals, such as rodents, and involve only a single administration of a noxious stimulus. In this study, an inflammatory soup (10 μL), consisting of prostaglandin E2 (0.2 mM), serotonin (2 mM), bradykinin (2 raM) and histamine (2 raM), was injected into the dura mater of conscious rhesus monkeys through an indwelling catheter. The infusion started on day 8 and was repeated every 3 days, for a total of six administrations, to induce neurogenic inflammation. We performed behavioral assessments and measured the expression of the oncogene c-fos, neuronal nitric oxide synthase (nNOS) and calcitonin gene related peptide (CGRP) ill the trigeminal system and in multiple brain regions involved in pain processing by immunohistochemical staining. Compared with monkeys in the control group, three of the four animals in the inflammatory soup group displayed decreased motor behaviors, and two showed increased ipsilateral nose and mouth secretions during the stimulus period. Higher expression levels of c-fos, nNOS and CGRP were found in various brain areas of experimental animals compared with controls, including the trigeminal nucleus caudalis, thalamus, hypothalamus, midbrain, pons and other areas involved in pain perception. These results suggest that repeated inflammatory soup stimulation of the dura activates the trigeminovascular system and produces migraine-like pathological changes and abnormal behaviors in conscious rhesus monkeys.

文摘This multiple-case study examined factors that could contribute to a richer understanding of top managers' perceptions on maintaining high-performance teams in Pharma R&D. In addition, this multiple-case study investigated top managers' perceptions of building opportunity-based entrepreneurial culture in organizations during strategic change, considered as a critical factor for organizations during change, the results of which can be used to guide management in preventing destructive actions of business non-loyalty. Following, this multiple-case study examined the management of change within the corporate entrepreneurship literature as a means of helping organizations improve practical intelligence of defining growth goals and new enterprise growth management processes and procedures, including those relevant to change, the way they function, and formal and informal rules protecting adequacy of governance arrangements as well as the organizational culture. Participant responses to the interview question regarding capability to maintain high-performing teams resulted in themes regarding role of leadership in risk management approach, leadership development challenges, trust and commitment in inter-fLrm relationships, as being the top managers' perceptions and the attitudes in outsourcing R&D industry sector since the enactment of the strategic change.
文摘CKD (chronic kidney disease) is a progressive disease. If it is left untreated, it can eventually result in end stage renal failure and necessitate dialysis or kidney transplantation. There is no cure for CKD; instead a great deal of self management over time is essential. The purpose is to evaluate self management behaviour of patients at different stages of CKD. A total of 300 CKD patients were recruited in this cross sectional study from March to July 2015 at nephrology clinic of a tertiary care setting using convenience sampling. Self management behaviour score was determined using in Partners in Health scale and was then compared at different stages of CKD. Demographic and clinical factors contributing to self management behaviour were determined. Results: There was a significant difference in age (p 〈 0.001), gender (p 〈 0.001), education level (p 〈 0.001), marital status (p 〈 0.001), duration of illness (p 〈 0.001) and number of co-morbidities (p 〈 0.001) among CKD stages. A significant difference in self management behaviour mean score was found among CKD stages (p 〈 0.001). Post hoc analysis showed self management behaviour mean score for Stage Ⅰ (mean ± SD: 77.81 ± 9.41) was significantly higher than Stage Ⅳ (mean ± SD: 70.53 ± 13.91) and Stage Ⅴ (mean ± SD: 69.54 ± 12.31). Self management behaviour mean score for Stage Ⅱ (mean ± SD: 78.46 ± 10.01) was significantly higher than Stage Ⅳ and Stage Ⅴ. Multiple linear regression revealed education level (p 〈 0.001) and number of co-morbidities (p = 0.01) as significant predictors of self management behaviour. It can be concluded that special attention should be focused on patients at late stage of CKD, especially those with diabetic nephropathy; low education level and multiple co-morbidities to improve self management behaviour.
