Devonian Sea-Level Change Rhythms in South China and Coupling Relationships Among the Earth-spheres

Twenty orthosequences and their corresponding sea-level change (SLC) cycles have been recognized in the Devonian overlying the Caledonian unconformity, of which 9, 5.5 and 5.5 occurred in the Lower, Middle and Upper Devonian respectively. They can be grouped into 4 orthosequence sets, in which the maximum flooding surfaces lie in the sulcutus Zone (D12), perbonus Zone (D13), Middle and Upper varcus Zone (D22) and gigas Zone (D21) respectively. Four instant palaeogeographical reconstructions of South China have been made in the Emsian and Givetian. Devonian sea-level change rhythms of South China can be divided into 3 categories: the autorhythmic, the worldwide and regional allorhythmic, and the coupling-rhythmic. They developed respectively in the Famennian, Pragian, Eifelian, Lochkovian, Emsian, Givetian, Frasnian and the F / F (between the Frasnian and Famennian) event. The cause of the worldwide allorhythmic SLC of the Pragian and Eifelian under comparatively dry, warm and tranquil conditions may be related to the pulsating expanding and contracting of the oceanic basin volume or the earth volume pulsation, rather than the common glaciation and plate tectonism. The coupling-rhythmic SLC related to the F/ F event is a sensitive indicator of the interaction between terrestrial and extraterrestrial factors, and coordinated action among the earth-spheres.

Listening Barriers Among Chinese Students And Training Tactics

Listening is very important in the learning of English language. Most of our Chinese students regard listening comprehension as the most difficult part among all kinds of examinations. So if we can find the reasons why the students exist such barriers that prevent them from understanding, and give them ways of training it, I’m sure it will help the students to improve their ability of language learning.

Stroke and Cardiovascular Disease among Women

Stroke falls under the umbrella of cardiovascular disease (CVD), which is the number one killer of Americans. CVD, including stroke and heart disease, takes about 267,000 women’s lives every year [1]. In the present study, a health risk assessment of a population of women residing in North-eastern Pennsylvania was conducted to provide an estimate of vulnerability to stroke on the basis of medical history, genetic predisposition, and other lifestyle factors. Using the Health Belief model of Rosenstock, Strecher, and Becker [2] and the stage model of Prochaska, Diflemente, and Norcross [3], a health promotion plan was developed to address the needs of that population. An evaluation of risks that can and cannot be modified is developed to help people understand the basic lifestyle changes that could be made to prevent CVD, which includes stroke. An action plan was developed to lower the risk of stroke among women based on their individual needs and to raise awareness throughout the United States. Individuals should take the essential precautions for their personal cases. This will substantially lower the risk of CVD, especially stroke, among women.

HIV/AIDS Related Stigma among Male Labor Migrants in Nepal

Labor migrants are those of the at-risk groups for HIV. This cross-sectional study has tried to examine HIV/AIDS-related stigma among Nepalese returnee male labor migrants. Migrant workers who have worked at least six months abroad were asked different questions related to sexual behavior, knowledge on HIV/AIDS & condom and HIV/AIDS-related stigma. Stigma was measured on a three-point rating scale as high, average and low stigma. About 58% of migrants had the view “I would rather not know if I have HIV” followed by “I don’t want to be friends with people living with HIV” (53.6% migrants) and “people with HIV are cursed” (35.5% migrants). High stigma was present among 15.5% of the total respondents with high proportion among those with higher age, lower education, rural residence, and no knowledge on Voluntary Counseling and Testing (VCT) service. About a quarter of respondents were of the view that migrants infected with HIV while abroad should not be allowed to return Nepal. Some level of stigma on HIV/AIDS exists among male labor migrants in Nepal. Interventions aiming at reducing stigma should consider the factors like migrants’ age, education, place of residence and knowledge on VCT services.

Differences in Self-Assessment Regarding Eating Behaviors among Female University Students Living in Japan, Korea, and Austria

Objective: To investigate cross-cultural differences in self-assessments of eating behaviors of female university students who bear responsibility for their own eating behaviors and who will, in the future, likely determine a family’s eating style. Design: A cross-cultural comparison. Setting: Japan, South Korea, and Austria. Subjects: Female university students from Japan (n = 276), Korea (n = 103), and Austria (n = 127). The survey comprised a questionnaire containing ten sections about eating behaviors (eating habits, regular meal times, and frequency of food intake) and eating attitudes. Results: Eating behaviors and attitudes differed significantly among the three cultures. Japanese students practiced healthier eating behaviors than did Korean and Austrian students, on the basis of their variety of food intake and regular consumption of three meals, but rated themselves lower on healthy eating behaviors. Austrian students tended to have more independent attitudes toward eating and food preparation (e.g., “I want to eat only my favorite dishes”) than Japanese or Korean students. Conclusions: Effects of cultural differences in psychological processes, such as self-cognition, emotion, motivation, and values, on self-assessment of eating behaviors is suggested.

Delirium Severity and Correlates among Medical Inpatients Admitted through Accident and Emergency Unit of Jos University Teaching Hospital

Background: Delirium is one of the most common medical emergencies and is associated with poor outcomes including: mortality, prolonged length of stay and poor functional outcome. The more severe delirium is the worst the clinical outcomes of medical illness. Despite the obvious, not much has been documented on delirium severity and its associated factors among medical inpatients in low income countries including Nigeria. Objectives: This study was conducted to examine the severity of delirium among medical inpatients admitted through the Accident and Emergency unit of Jos University Teaching Hospital as well as to assess its associated Sociodemographic and Clinical characteristics. Method: This was a cross-sectional study that employed a consecutive sampling technique to select 290 eligible subjects from medical inpatients that presented to Accident and Emergency unit of Jos University Teaching Hospital. On admission, patients were assessed for delirium using Confusion Assessment Method and severity of delirium was evaluated using Delirium Rating Scale-Revised-98. Results: Of the 105 delirious medical inpatients, 48 (45.7%) had severe delirium, 41 (39.1%) developed less severe delirium while 16 (15.2) presented with no severe delirium. Sociodemographic characteristics found to be significantly associated with less to more severe delirium include male gender (P = 0.001), nonprofessionals (P = 0.003), income range of N20,000 - N49,000 (P Conclusion: This study demonstrates that delirium is often associated with higher severity in Accident and Emergency unit admission and there are strongly associated clinical characteristics to watch out for in high risk medical inpatients.

Prevalence of Dyspareunia and Its Effect on Sexual Life among Gynaecological Clinic Attendees in Alex Ekwueme Federal University Teaching Hospital Abakaliki, Nigeria

Introduction: Dyspareunia is one of the most common complaints in gynae-cologic practice with tremendous effect on both quality of life and sexual rela-tionship of women. Objectives: To determine the prevalence of dyspareunia and its effect on sexual life among gynaecology clinic attendees in Alex Ekwueme Federal University Teaching Hospital, Abakaliki. Materials and Methods: A cross-sectional study was conducted on consenting participants between 12th May 2016 and 25th July 2016. Anonymous self-administered questionnaires were used collection information on dyspareunia and its effect on sexual life at the Gynaecology clinic. The data was analyzed using Epiinfo version 7.1.5. Results: One hundred and four (104) women participated in this study. Most of the women studied were Igbos (95.19%), and were mainly between the age ranges of 21 - 30 years (66.35%). Most of them were married (89.42%), and were also mainly of the Pentecostal denomination (40.78%). The mean age at coitarche was 20.6 ± 3.95 years. Prevalence of dyspareunia was 36% and only 16% sought medical help. The various responses to dyspareunia were avoidance of sex 11%, reduced frequency of intercourse 8%, less desire for sex 19%, while majority of women with dyspareunia tolerated it (62%). Conclusion: The prevalence of dyspareunia is high in our society afflicting young women in their reproductive years with associated enormous stress on their sexual life.

The Prevalence of Drug-Resistant Tuberculosis among People Living with HIV (PLHIV) in Abia State

Tuberculosis (TB) is a chronic disease caused by mycobacterium tuberculosis and transmitted from person to person, through inhalation of droplet nuclei aerosolized by coughing of an infected person. It reached epidemic proportions in Europe and North America during the 18th and 19th centuries. The incubation period is 2 - 6 weeks and the control has been complicated with emergence of HIV and drug-resistant TB. In 1993, World Health Organization (WHO) declared TB a global emergency. However, despite the concerted effort of National TB control programs, adoption and implementation of Stop TB strategy, TB has remained a major public health challenge with high mortality rate, especially in developing countries. Methodology: This is a descriptive study, evaluated using the positivist/quantitative approach. The study was conducted at FederalMedical Centre Umuahia, a tertiary specialist hospital with comprehensive TB/HIV treatment services. All the presumptive drug-resistant TB cases and symptomatic PLHIV were screened for HIV and their sputum specimens were tested for tuberculosis using the Gene xpert and the Ziehl- Neelsen technique for detecting Acid Fast bacilli. A pretested structured questionnaire was used tocollect the demographic data and other essential data from the presumptive TB and laboratory registers such as total number of TB presumptive cases registered HIV status, AFB status and rifampicin status within the study period. Result: A total of 493 presumptive TB cases were screened in the study, 49.9% were HIV positive while 50.05% were HIV negative. More so, 77.85% of thescreened cases were AFB negative and 22.15% were AFB positive. Moreover, 11% of the TB/HIV co-infected patients were rifampicin positive. Interestingly among the 493 cases screened with gene xpert machine, 3.6% were rifampicin positive. Furthermore, 3.6% of the HIV negative cases were rifampicin positive while 1.6% of the HIV positive cases were rifampicin positive. Discussion: The data depict lower rifampicin resistance among HIV positive cases than HIV negative cases. The implication for public health professionals is to intensify equitable and unbiased search for resistant TB cases among smear negative and positive cases.

Strategic interaction among local governments, fiscal spending competition and regional economic growth

Using a spatial econometric model, this paper investigates strategic interaction among provincial governments regarding expenditures, the mechanism behind expenditures interaction and their effects on economic growth in China. Our conclusion is as follows: Significant strategic interaction exists among provincial governments regarding expenditures mainly owing to fiscal competition mechanism in China, and expenditures interaction has changed significantly since tax sharing system reform, which has had positive effects on regional economic growth. This conclusion has significant implications for the optimization of public functions, size and structure of local governments in China.

Work-family conflict and job burn-out among Chinese doctors:the mediating role of coping styles

Background Burn-out among doctors threatens their own health, and that of their patients. To identify risk factors of the doctor burn-out is vital to improving their health and increasing the quality of healthcare services.This study aims to explore the relationship between workfamily conflict(WFC) and burn-out among Chinese doctors and the mediating role of coping styles in this relationship.Methods A cross-sectional survey was conducted in China, with a questionnaire packet which consisted of the Chinese Maslach Burnout Inventory(CMBI), WFC Scale and the Simplified Coping Style Questionnaire(SCSQ). A total of 2530 doctors participated in the survey. Correlation analysis was performed to explore the relationship between CMBI, WFC and SCSQ scores. A linear regression model was set to determine the mediating role of coping styles on the relationship between WFC and burn-out.Results Doctors who had higher scores on work interfering with family conflict, reported more emotional exhaustion(r=0.514, P<0.001) and had a sense of accomplishment(r=-0.149, P<0.001). Simultaneously,family interfering with work(FIW) was positively associated with all dimensions of burn-out(r=0.213,0.504,0.088,respectively, P<0.001). Coping styles had partial, complete and even mediating effects on the relationship between WFC and burn-out among Chinese doctors.Conclusions WFC was correlated with burn-out, and coping style was a mediator in this relationship among Chinese doctors. Coping style was a positive resource against burn?out.

一种融合个性化细胞关系和背景信息的宫颈细胞分类方法

宫颈细胞分类在宫颈癌辅助诊断中发挥着重要的作用。然而,现有的宫颈细胞分类方法未充分考虑细胞关系和背景信息,也没有模拟病理医生的诊断方式,导致分类性能较低。因此,该文提出了一种融合细胞关系和背景信息的宫颈细胞分类方法,由基于细胞关系的图注意力分支(GAB-CCR)和背景信息注意力分支(BAB-WSI)组成。GAB-CCR采用细胞特征间的余弦相似度,首先构建相似和差异细胞关系图,并利用GATv2增强模型对细胞关系建模。BAB-WSI使用多头注意力模块捕捉涂片背景上的关键信息并反映不同区域的重要性。最后,将增强后的细胞特征和背景特征融合,提升了网络的分类性能。实验表明,相比于基线模型Swin Transformer-L,所提方法在准确率、敏感度、特异性和F1-Score分别提高了15.9%,30.32%,8.11%和31.62%。

基于游客视角的旅游促进“三交”机理研究

旅游提供了各民族接触、了解、互动的场域,但其如何促进“三交”的内在机理还未明确。基于认知-情感-意动理论,从游客视角探索旅游促进“三交”的机理,发现:游客旅游体验、旅游满意度、旅游认同、“三交”行为具象共同构成了旅游促进“三交”的机制模型,其中,旅游满意度、旅游认同(中华民族共同体认同、地方认同)在这其中起链式中介作用。旅游促进“三交”中要平衡营利性与公益性、融合性的关系,协调求异性与共同性、统一性的关系,统筹推进体验性与互嵌性。基于游客视角,可以从拓展旅游时空、提升游客体验、强化国家感知等方面来铸牢中华民族共同体意识。
