The impact of work support and organizational career growth on nurse turnover intention in China

Objective:The paper aimed to explore the impact of work support and potential for career advancement on the nurse turnover intention in order to find an effective approach to curb high turnover.Methods:A cross-sectional survey of 526 nurses from eight teaching hospitals in Tianjin,China,was conducted to test the hypothesized multilevel model.The organizational career growth scale,work support scale,and the nurse turnover intention scale were used to measure the effect of organizational career growth and work support on nurse turnover intention.Finally,SPSS 17.0 and AMOS 17.0 software were used to analyse the relationship of these variables.Results:The score of the three scales nurse turnover,organizational career growth,and work support were 1.98±0.60,2.40±0.50,and 4.06±0.98,respectively.The total and direct effects of work support on turnover intention were
0.361(p<0.01)and
0.147(p<0.01),respectively.The indirect effect was
0.169 with a 95%bootstrap confidence interval of
0.257 to
0.102.Conclusion:The study showed a lack of work support negatively and directly associated with nurse turnover intention.Additional opportunities for career growth within the organization may strengthen the effect of work support and consequently increase the retention of qualified nursing staff.

UOUU:User-Object Distance and User-User Distance Combined Method for Collaboration Task

Augmented reality superimposes digital information onto objects in the physical world and enables multi-user collaboration.Despite that previous proxemic interaction research has explored many applications of user-object distance and user-user distance in an augmented reality context,respectively,and combining both types of distance can improve the efficiency of users’perception and interaction with task objects and collaborators by providing userswith insight into spatial relations of user-task object and user-user,less is concerned about howthe two types of distances can be simultaneously adopted to assist collaboration tasks acrossmulti-users.To fulfill the gap,we present UOUU,the user-object distance and user-user distance combined method for dynamically assigning tasks across users.We conducted empirical studies to investigate how the method affected user collaboration tasks in terms of collaboration occurrence and overall task efficiency.The results show that the method significantly improves the speed and accuracy of the collaboration tasks as well as the frequencies of collaboration occurrences.The study also confirms the method’s effects on stimulating collaboration activities,as the UOUU method has effectively reduced the participants’perceived workload and the overall moving distances during the tasks.Implications for generalising the use of the method are discussed.

The effect of traditional Chinese medicine──Tian Gui Recipeon obesity and anovulation in androgen-sterilized rats

Objective: A traditional Chinese medicine Tian Gui Recipe (TGR) has been used to effectively treat clomiphene resistant anovulatory disease and obesity, especially in polycystic ovary syndrome (PCOS) cases with hyperinsulinemia. The effect of TGR on obesity and anovulation was investigated in androgen-sterilized rats (ASR). Methods: Female SD rats at the age of 9 days were divided into 3 groups. Group ASR (n=15): anovulation was demonstrated at the age of 70 days by vaginal smear in rats while 1. 25 mg of testosterone propionate was injected subcutaneously on its 9th neonatal day. Group A+H (n = 25): TGR were administered to ASR at the age of 80 days for 3 weeks. Rats with regular estrous cycle and ovulation after herbal treatment were included in this group. Group C (n = 15): normal ovulated rats were recruited. Around the age of 112 days or on proestrous day, all rats were sacrificed under anesthesia. Serum leptin, testosterone (T), estrogen (E2), follicular stimulating hormone (FSH), luteinizing hormone (LH) levels were measured with radioimmunoassay (RIA). Double immunofluorescent staining combined with confocal laser scanning microscope and dual in situ hybridization were carried out on sections through areas of arcuate nucleus (ARC) to determine whether estrogen receptor (ER) immunoreactivity (IR) or long form of leptin receptor (OB-Rb) mRNA were expressed in neuropeptide Y (NPY) immuno-and mRNA-containing neurons, and its relationship to proopiomelanocortin (POMC) mRNA-containing neurons. Immunohistochemistry and in situ hybridization were used to observe the levels of ER, NPY, gonadotrophin releasing hormone (GnRH) and gene expression levels on NPY, OB-Rb, POMC. Meanwhile, the criteria of energy state, including daily food intake, retroperitoneal fat depot pad and body weight, were measured and evaluated. Values of immunohistochemistry and in situ hybridization were expressed in mean optic density (MOD). Results: Seventeen out of the 25 rats (68%) in Group A+H were ovulated after herbal treatment. ASR characterized with significantly high metabolic rate, energy imbalance and obesity (P<0. 01, P<0. 01, P<0. 01). The mean serum leptin, T, E2 levels of group ASR were significantly higher than those of Group C and Group A+H (P< 0. 01,P<0. 01 ), while FSH, LH levels were lower (P<0. 01, P<0. 01 ). ERs were proved to be distributing in NPY-containing neurons, OB-Rb coexpressed in NPY-syn- thesizing neurons, and both NPY and POMC mRNA expressing neurons overlapped in ARC. Compared to Group C, levels of NPY mRNA and NPY, POMC mRNA expressions were increased (P<0. 01, P<0. 01, P<0. 01 ), OB-Rb mRNA, ER and GnRH immunoreactive expression were decreased significantly in the hypothalamus of ASR (P<0. 01, P<0. 01, P<0. 01 ). These dramatic neuroendocrine changes became normal in ovulated ASR after the herbal treatment (all P>0. 05). Conclusion: The elevated peripheral E2 caused by high T and leptin levels in ASR may down-regulate their corresponding receptors oriented on hypothalamic NPY- containing neurons respectively, therefore challenge the NPY mRNA and NPY, POMC mRNA overexpressions. The overexpression, of NPY, POMC gene transcription and translation stimulate food intake, promote the deposit of adipocyte tissue, and inhibit GnRH expression and GnRH/FSH, LH release, which contribute to the occurrence of obesity and anovulation in ASR. TGR may reverse these abnormal neuroendocrine cascades by lowering the levels of T, E2 and leptin.

A Method for Forecasting Credit Risk of Global Device Purchasing

With the development of the Internet and E commerce, enterprises can achieve global device purchasing with a good cost performance. But the credit risk is the key factor in selecting a device provider. Credit risk involves many qualitative and quantitative factors. We construct a multi agent credit rating model system based on CSCW, which organically combines the people's aptitude and the capability of machines. Enterprises can use this credit rating system for forecasting and defeating the credit risk of global device purchasing.

oodOPT: A Semantics-Based Concurrency Control Framework for Fully-Replicated Architecture

Concurrency control has always been one of the most important issues in the design of synchronous groupware systems with fully-replicated architecture. An ideal strate- gy should be able to support natural and flexible human-to-computer and human-to-human interactions while maintaining the consistency of the system. This paper summarizes previ- ous researches on this topic and points out the deficiencies of the existing results. A novel semantics-based concurrency control framework, oodOPT is proposed. The main idea of the framework is to resolve conflicts by utilizing semantics of the operations and the accessed data objects. With this approach, complexities in concurrency control are shifted completely from application developers to the framework. Conflicts among operations on objects with different semantics and the strategies resolving these conflicts are analyzed. After describing the algo- rithm in full detail, the discussion ends up with a comparison with other related work and some considerations for open problems.

Collaborative eye tracking based code review through real-time shared gaze visualization

Code review is intended to find bugs in early development phases,improving code quality for later integration and testing.However,due to the lack of experience with algorithm design,or software development,individual novice programmers face challenges while reviewing code.In this paper,we utilize collaborative eye tracking to record the gaze data from multiple reviewers,and share the gaze visualization among them during the code review process.The visualizations,such as borders highlighting current reviewed code lines,transition lines connecting related reviewed code lines,reveal the visual attention about program functions that can facilitate understanding and bug tracing.This can help novice reviewers to make sense to confirm the potential bugs or avoid repeated reviewing of code,and potentially even help to improve reviewing skills.We built a prototype system,and conducted a user study with paired reviewers.The results showed that the shared real-time visualization allowed the reviewers to find bugs more efficiently.

Impact of Industry 4.0 in service oriented firm

The first part of this study is devoted to concepts, approaches and some examples of the fourth industrial revolution. The basis of this revolution also well known as Industry 4.0 builds so called cyber-physical systems. They contain the integrated smart software systems including the internet address to enable the communication with envi- ronment as for product itself as for means of production and employees. All these enable the next level of efficiency and flexibility for both organizing and controlling of the value-creation chain over the whole lifecycle of products. In the first three chapters several Internet references and documents published by German Federal Ministry for Economic Affairs and Energy were used. Because of multiple cross references in documents, this report is written without detailed references in each paragraph of mentioned chapters. The last three chapters of the research presented undertake the short review of interdependencies between the Industry 4.0 and the well-known approach of computer-supported-cooperative-work established in the late 1980s. Long list of publications can be found in Wikipedia, and in many proceedings of ACM conferences on computer supported cooperative work （CSCW）.

Social Computing Unhinged

Social computing is ubiquitous and intensifying in the 21st Century.Originally used to reference computational augmentation of social interaction through collaborative filtering,social media,wikis,and crowdsourcing,here I propose to expand the concept to cover the complete dynamic interface between social interaction and computation,including computationally enhanced sociality and social science,socially enhanced computing and computer science,and their increasingly complex combination for mutual enhancement.This recommends that we reimagine Computational Social Science as Social Computing,not merely using computational tools to make sense of the contemporary explosion of social data,but also recognizing societies as emergent computers of more or less collective intelligence,innovation and flourishing.It further proposes we imagine a socially inspired computer science that takes these insights into account as we build machines not merely to substitute for human cognition,but radically complement it.This leads to a vision of social computing as an extreme form of human computer interaction,whereby machines and persons recursively combine to augment one another in generating collective intelligence,enhanced knowledge,and other social goods unattainable without each other.Using the example of science and technology,I illustrate how progress in each of these areas unleash advances in the others and the beneficial relationship between the technology and science of social computing,which reveals limits of sociality and computation,and stimulates our imagination about how they can reach past those limits together.

Research of Consistency Maintenance Mechanism in Real-Time Collaborative Multi-View Business Modeling

Real-time collaborative editing(RTCE)can support a group of people collaboratively work from distributed locations at the same time.However,consistency maintenance is one key challenge when different types of conflicts happen.Therefore a common synchronous mechanism is proposed to support consistency maintenance in the process of multi-view business modeling.Based on operation analysis on different views of models in the real-time collaborative editing system,detection of potential conflicts is realized by means of a decision-making tree.Then consistency maintenance provides a comprehensive and applicable conflicts detection and resolution for collaborative business modeling.Finally,a prototype of collaborative multi-view business modeling system is introduced to verify the approach.The point is that the mechanism proposes a comprehensive solution for collaborative multi-view business modeling.
