A Research Conception on Indigenous Chinese Leadership:Based on Comparative Case Studies on Political Elites in Ancient China

Due to the complexity of leadership and its variability across situations,it is suggested that research on leadership should focus on attempts to understand leadership in specific situations or roles,and develop local knowledge about leadership in each situation or role.This paper validates the possibility and importance of building indigenous leadership theories from historical perspective.We demonstrated how to carry out research on indigenous Chinese leadership from a historical perspective by comparative case studies using historical data.Based on the principles of typicalness,representativeness,and comparativeness,we selected six counterparts of political elites in ancient China as comparative cases,which includes Guan Zhong&Shang Yang(organizational reformer),Liu Bang&Xiang Yu(entrepreneur),Li Shimin&Qin Shihuang(intergenerational transition successor),Zhuge Liang&Zeng Guofan(professional manager),Lu Su&Zhang Juzheng(mess-to-order maker),and Zuo Zongtang&Wang Anshi(national dream driver).The paper aims to develop indigenous leadership theory specific to Chinese mental states and culture.

Periodontal disease is associated with increased coronary heart disease risk:A meta-analysis based on 38 case-control studies

AIM: To investigate whether periodontal disease(PD) is associated with increasing coronary heart disease(CHD) risk by performing a meta-analysis.METHODS: Two authors independently searched Pub Med and China National Knowledge Infrastructure up to January 10 th, 2013 for relevant case-control studies that investigated the association between PD and CHD. After quality assessment using Newcastle-Ottawa Scale and data extraction by two independent authors, the overall and subgroup meta-analyses were performed and publication bias were examined using the Comprehensive Meta-Analysis V2 software. Potential publication bias was assessed using visual inspection of the funnel plots, Egger linear regression test, and trims and fill method.RESULTS: Finally 38 relevant case-control studies were identified, involving 4950 CHD patients and 5490 controls. Eleven studies were rated low quality and 27 were high quality. Based on random-effects, a significant association was identified between PD and CHD(OR 3.79, 95%CI: 2.23-6.43, P < 0.001, I2 = 98.59%), and sensitivity analysis showed that this result was robust. Subgroup analyses according to adjusted/unadjusted ORs, source of control, methodological quality, end point, assessment of PD/CHD, and ethnicity also indicated a significant association. Publication bias was detected, and the estimated OR including the "missing" studies did not substantially differ from our estimate with adjustment for missing studies(OR 4.15, 95%CI: 2.62-6.54, P < 0.001).CONCLUSION: Based on the meta-analysis, PD is probably associated with CHD risk independently and significantly.

Study design in evidence-based surgery:What is the role of case-control studies?

Randomized controlled trials(RCTs) are the gold standard in terms of study design, however, in the surgical setting conducting RCTs can often be unethical or logistically impossible. Case-control studies should become the major study design used in surgical research when RCTs are unable to be conducted and definitely replacing case series which offer little insight into surgical outcomes and disease processes.

CASE-CONTROL ASSOCIATION STUDIES OF THE UBAP1 GENE AND NASOPHARYNGEAL CARCINOMA IN SOUTHERN CHINESE

Objective: To identify the relation between nasopharyngeal carcinoma and the human novel gene UBAP1, which is located in the region of minimal heterozygosity deletion at 9pl3.2 and down-expressed in NPC. Methods: Five single nucleotide polymorphisms (SNPs) within UBAP1 gene were analysed by sequencing in 105 NPC patients and 183 control subjects which matched to the NPC cases on age, sex and residence. Results: Significant association was found between NPC with one SNP mark (rs1049557), which is located at 3' non-region of UBAP1 gene; the relative risk of this SNP mark is 1.64 (genotype GG) and 1.31 (genotype CG). Conclusion: The result has proved again that UBAP1 gene may play a certain role in the occurrence and development of nasopharyngeal carcinoma. The SNP mark rs1049557, considering its location, may influence the expression of UBAP1 gene.

Reducing Participation Bias in Case-Control Studies: Type 1 Diabetes in Children and Stroke in Adults

Background: Case-control studies have been used extensively in determining the aetiology of rare diseases. However, case-control studies often suffer from participation bias in the control group, resulting in biased odds ratios that cause problems with interpretation. Participation bias can be hard to detect and is often ignored. Methods: Population data can be used in place of the possibly biased control group, to investigate whether participation bias may have affected the results in previous studies, or in place of controls in future studies. We demonstrate this approach by reanalysing and comparing the results of two case-control studies: Type 1 diabetes in Yorkshire children and stroke in Indian adults. Findings: Using population data to represent the control groups reduced the width of the confidence intervals given in the original studies and confirmed the findings for the two diabetes risk factors used;caesarean birth (odds ratio (OR) = 2.12 (1.53, 2.95) compared with 1.84 (1.09, 3.10)) and amniocentesis (OR = 3.38 (2.09, 5.47) compared with 3.85 (1.34, 11.04)). The three stroke risk factors investigated were found to have increased odds ratios when using population data;hypertension (OR = 5.645 (5.639, 5.650) compared with 3.807 (2.114, 6.856)), diabetes (OR = 12.212 (12.200, 12.224) compared with 3.473 (1.757, 6.866)) and smoking (OR = 5.701 (5.696, 5.707) compared with 2.242 (1.255, 4.005)). Interpretation: Participation bias can greatly affect the results of a study and cause some potential risk factors to be over-or underestimated. This approach allows previous studies to be investigated for participation bias and presents an alternative to a control group in future studies, while improving precision.

Selected elements of rock burst state assessment in case studies from the Silesian hard coal mines

Exploitation of coal seams in the Upper Silesian Coal Basin is conducted in complex and difficult conditions. These difficulties are connected with the occurrence of many natural mining hazards and limitations resulting from the existing in this area surface infrastructure. One of the most important problems of Polish mining is the rock burst hazard and reliable evaluation of its condition. During long-years’ mining practice in Poland a comprehensive system of evaluation and control of this hazard was developed. In the paper the main aspects of rock burst hazard state evaluation will be presented, comprising: 1) rock mass inclination for rock bursts, i.e., rock strength properties investigation, comprehensive parametric evaluation of rock mass inclination for rock bursts, prognosis of seismic events induced by mining operations, methods of computer-aided modelling of stress and rock mass deformation parameters distribution, strategic rock mass classification under rock burst degrees; 2) immediate seismic and rock burst hazard state evaluation, i.e., low diameter test drilling method, seismologic and seismoacoustic method, comprehensive method of rock burst hazard state evaluation, non-standard methods of evaluation; 3) legal aspects of rock burst hazard state evaluation. Selected elements of the hazard state evaluation system are illustrated with specific practical examples of their application.

Site-specific Vulnerability Assessment for Debris Flows: Two Case Studies

Here the vulnerability is defined as the potential total maximum losses due to a debris flow damaging event for a specific debris flow fan. The vulnerability is classified into property vulnerability and population vulnerability. Assessment indexes include the assets of buildings, traffic facilities, lifeline works, personal properties, and land resources for property vulnerability; age, education, and wealth of the inhabitants, natural population growth rate, and population density for population vulnerability. The vulnerability is expressed as the sum of the transformed values of the losses of property and population. Two study cases with post-fact damages by historic debris flow events in Sichuan of SW China are presented.

Efficacy of Photobiomodulation for Attention Deficit Hyperactivity Disorder (ADHD): Case Studies

Extensive research has now been conducted and published for the treatment of dementia or Alzheimer’s disease, traumatic brain injury (TBI) and other brain disorders using photobiomodulation (PBM), also known as low-level laser therapy (LLLT). However, minimal information is available regarding the use of LLLT for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). We have been using LLLT in our practice for over 15 years addressing chronic pain and injury issues. However, our work with brain injuries is more recent, and we have published three case studies, one describing a serious traumatic brain injury and two describing our success with dementia/Alzheimer’s disease and PTSD. Currently, there is very little published evidence regarding efficacious therapy for ADHD. The case studies presented here, suggest that LLLT can provide alleviation of these symptoms, with some improvement reported after just a single treatment, without any need for pharmaceutical intervention.

Case studies in psychotherapy training using Austria as an example

BACKGROUND Case studies(CS)are relevant for the development of theoretical and practical competencies in psychotherapy.Despite rapid progress in the development of methods and principles for establishing CS in the last three decades,research into the aims of CS,especially in training,or how CS are to be conducted is rare.AIM To elucidate the form and methodology of CS,the objectives of CS used in training institutions(TI),and if/how TIs handle therapist allegiance.Also,this preliminary investigation will suggest avenues for further research and attempt to establish certain guidelines.METHODS In order to counteract researcher bias and enlarge the question-pool,a focus group was established.The recorded and transcribed text was analyzed with Mayring’s method of qualitative content analysis,and the generated categories were formulated as questions.The resulting questionnaire with both qualitative and quantitative queries was sent out(after pre-testing)to all 39 Austrian TIs that provide professional psychotherapy training.The answers and text passages received were then also categorized with qualitative content analysis.Data analysis was discussed by a peer group consisting of three psychotherapists trained in differing schools of psychotherapeutic methods.RESULTS 94%of Austrian institutes use CS as part of their psychotherapeutic training.Understanding of the term“case study”is inconsistent and has a wide variety of interpretations.CS serve mainly:(1)For observation of training/progress in therapeutic practice and knowledge/acquisition of the theory specific to each psychotherapeutic school;(2)To improve(self-)reflection capabilities;and(3)To expand theoretical knowledge.Most of the CS written are not accessible for students nor for the research community.More than two thirds of the CS take only the position of the author into account(the client’s position is not described).15.5%of the TIs do not consider researcher or therapist allegiance at all.CONCLUSION A more precise formulation of the term case study is needed in psychotherapeutic training.The training therapists play a key function,as they exemplify and teach how to deal with distorting factors.General guidelines as to how to conduct CS in training institutions would provide more direction to students,increase scientific rigor,and enhance synergistic effects.

Misconceptions and truths for feeding patients in the intensive care unit: Case studies with practical nursing solutions

The Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient published in May 2009 (joint guidelines between the Society of Critical Care Medicine (SCCM) and the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) have advanced our clinical practice for the nutritional management of critically ill patients. In the current article, we will review how to implement these guidelines using a case study model. Two mechanically ventilated and tube fed patients are discussed, one with pneumonia and the second with severe acute pancreatitis. We address the questions of the feeding timing, method of administration, and management of its complications for these two patients.

Examination of Three Case Studies of Caring for Psychiatric Patients on a Medical Surgical Unit

Medical surgical nurses frequently care for patients with psychiatric disorders as one in four people have a diagnosed psychiatric disorder. Since these nurses specialize in medical surgical nursing, they often feel they lack the expertise to care for patients with co-morbid psychiatric problems. This article presents three case studies and delineates nursing care strategies which could assist the medical-surgical nurses in caring for this population.

A Study on Applications and Case Studies Regarding Bluetooth Technology for Travel Time Measurement

Bluetooth technology emerged over twenty years ago and has continuously improved throughout the years to meet diverse and complex applications. Initially invented to replace the need for physical data cables, Bluetooth offers users a quick and easy way to share data files over a wireless network. Traffic engineers and transportation engineering researchers have utilized the potential opportunities that exist with Bluetooth and have implemented this technology into traffic monitoring techniques. To gain a better understanding of Bluetooth sensors and how they work, a comprehensive literature search was conducted. Twenty-five articles were studied regarding case studies of Bluetooth sensor implementation for travel time measurement. Besides reviewing the literature and previous case studies, three new case studies in the State of Delaware, USA, were also conducted and carefully analyzed. The benefits and drawbacks associated with Bluetooth technology for travel time measurements have been identified in this paper. The overall conclusion of the authors is Bluetooth alone and by itself is not a proper technology for travel time measurements. More studies need to be conducted on the accuracy and overall application, before one can confidently utilize the Bluetooth technology for travel time measurements.

Case Studies from Literature and Movies: A Best Practice for Learning

Pedagogy today has a greater need to focus on relevance for students between course content and the real world of student life and work.Educators across disciplines have found a challenge to engage students in learning activities that carry value for them.The case study is a pedagogical tool that can connect student learning to real life examples.Narratives from books and movies present characters and situations that provide opportunity for student analysis within course concepts and student application to both personal and professional experience.Students enter example experiences that they might encounter and gain insight of potential response.This qualitative study examined graduate course work with case studies in Life-span Development,Multi-cultural Counseling,and Traumatology in which students reviewed books and movies with case examples aligned with course content.The instructor provided structured analysis format in which students were required to reflect on both personal and professional application relevant to the focus of the course.Student responses indicated perception of strong value for insight and application gained from the case studies and also high perception of use of these as tools in their own future work as educators or mental health professionals.

Driving Forces of Private Equity Investment in China： Case Studies of Private Entrepreneurship

In search of private equity investment opportunities in China, one would be astonished by the rise of raw private entrepreneurship in this largest emerging market economy in the world. The country is experiencing a transition from a planned, socialist economy to a market or mixed economy. The emergence of a significant private sector is one of the most important developments of the market-oriented reforms in China over the last quarter of a century. It is true that the transformation of public ownership into private ownership indeed gave a rise to the new private enterprises. Nevertheless, there is also an origination process of genuine private enterprises parallel to this privatization approach. In this paper, the concept of raw entrepreneurship is introduced to distinguish new, green-field private firms from the rest of the private sector that has emerged from older firms that have been converted from SOEs （state-owned enterprises） or COEs （collectively-owned enterprises）. It is also a concept that stresses the highly innovative manner in which private firms have emerged in China. This paper will explore deeply the concept of raw entrepreneurship through three case studies as well as theoretical analysis based on traditional wisdom.

Delivering Tram-Based Boulevards: Learning from Opportunities and Challenges in Three European City Case Studies

Increasing calls for zero-carbon cities invite transformative solutions for people and places within our cities around the world. Key to the transformation is cities and regions shifting in mobility away from fossil-fuel based car-oriented solutions. The paper investigates a range of case studies where “tram-based boulevards” have been planned or implemented to provide such opportunities. The case studies share a common broader policy objective: to transform the car-oriented or car-saturated areas to an intensified urban template based on a critical presence of dedicated mid-tier transit infrastructure and active transport. “Trams”, or mid-tier, mid-capacity transit when combined with Transit oriented development (TOD) along whole corridors can provide transformative pathways towards zero-carbon outcomes as well as multiple, strong urban benefits. However, many successful or instructive examples of this practice from non-English speaking countries, particularly in Europe, are underdocumented in the international literature. The paper addresses this gap by investigating opportunities and challenges evident in a range of European case studies. These are explored for insight towards policy learning particularly in New World cities seeking to transform into a zero-carbon and more transit-oriented template: How can decision-makers avoid repeating the identified pitfalls, and instead focus on emulating the successful approaches and outcomes? We conclude the need for recognition of the inherent synergies between transport and land use settings in any endeavour, and their translation into policy priorities in both fields of planning. We also conclude the importance of decision makers proactively identifying and critically appraising specific opportunities for change, concerning funding, technology, public opinion, stakeholder alliances or market dynamics, and capitalising on them at suitable moments in time.
