Authors: Xu Zhenhui , Chen Hanlin 
Published: January 2015

Purpose
– The purpose of this paper is to reveal the dynamical behavior of higher dimensional nonlinear wave by searching for the multi-wave solutions to the (3+1)-D Jimbo-Miwa equation.

Design/methodology/approach
– The authors apply bilinear form and extended homoclinic test approach to the (3+1)-D Jimbo-Miwa equation.

Findings
– In this paper, by using bilinear form and extended homoclinic test approach, the authors obtain new cross-kink multi-soliton solutions of the (3+1)-dimensional Jimbo-Miwa equation, including the periodic breathertype of kink three-soliton solutions, the cross-kink four-soliton solutions, the doubly periodic breather-type of soliton solutions and the doubly periodic breather-type of cross-kink two-soliton solutions. It is shown that the extended homoclinic test approach, with the help of symbolic computation, provides an effective and powerful mathematical tool for solving higher dimensional nonlinear evolution equations in mathematical physics.

Research limitations/implications
– The research manifests that the structures of the solution to higher dimensional nonlinear equations are diversified and complicated.

Originality/value
– The methods used in this paper can be widely applied to the research of spatial and temporal characteristics of nonlinear equations in physics and engineering technology. These methods are also conducive for people to know objective laws and grasp the essential features of the development of the world.
Numerical investigation of fluid flow structure and heat transfer in a passage with continuous and truncated V-shaped ribs
Authors: Li Shian , Xie Gongnan , Sunden Bengt 
Published: January 2015

Purpose
– The employment of continuous ribs in a passage involves a noticeable pressure drop penalty, while other studies have shown that truncated ribs may provide a potential to reduce the pressure drop while keeping a significant heat transfer enhancement. The purpose of this paper is to perform computer-aided simulations of turbulent flow and heat transfer of a rectangular cooling passage with continuous or truncated 45-deg V-shaped ribs on opposite walls.

Design/methodology/approach
– Computational fluid dynamics technique is used to study the fluid flow and heat transfer characteristics in a three-dimensional rectangular passage with continuous and truncated V-shaped ribs.

Findings
– The inlet Reynolds number, based on the hydraulic diameter, is ranged from 12,000 to 60,000 and a low-Re k-e model is selected for the turbulent computations. The local flow structure and heat transfer in the internal cooling passages are presented and the thermal performances of the ribbed passages are compared. It is found that the passage with truncated V-shaped ribs on opposite walls provides nearly equivalent heat transfer enhancement with a lower (about 17 percent at high Reynolds number of 60,000) pressure loss compared to a passage with continuous V-shaped ribs or continuous transversal ribs.

Research limitations/implications
– The fluid is incompressible with constant thermophysical properties and the flow is steady. The passage is stationary.

Practical implications
– New and additional data will be helpful in the design of ribbed passages to achieve a good thermal performance.

Originality/value
– The results imply that truncated V-shaped ribs are very effective in improving the thermal performance and thus are suggested to be applied in gas turbine blade internal cooling, especially at high velocity or Reynolds number.
Variation theory based approaches to teaching subject-specific vocabulary within differing practical subjects
Authors: Driver Alice , Elliott Katherine , Wilson Andrew 
Published: January 2015

Purpose
– The purpose of this paper is to describe how a learning study model, guided by variation theory, can be used to improve lesson design and a pupil’s understanding of key words and vocabulary in the context of three different subjects, namely art, dance and science.

Design/methodology/approach
– Three lesson designs were used with three groups of pupils from the same year group. In each case, pupils were given either visual or audio stimuli to describe and compare prior to being introduced to the keywords. Pupil interviews, observations and pre- and post-lesson tasks were used in each case to assess the success of the strategy and the impact it had on the understanding of different ability-level students. The results from each lesson were analysed and utilised to improve the design of the subsequent lesson.

Findings
– The results of the study found that this approach was successful, with pupils able to produce their own definitions, including a reference to relevant critical features following the lesson, and that in most cases this information was retained. The strategy was most effective at reinforcing concepts and vocabulary, and was preferred by low- and mid-ability pupils, whereas higher-ability pupils preferred to use specific terminology from the outset.

Originality/value
– Many published learning studies have been carried out within subjects, concentrating on a particular learning object that pupils have difficulty with. In this study the authors have demonstrated that this approach can also be employed as a successful approach to promote pupil learning across different subjects.
Logistics performance management in textiles supply chains: best-practice and barriers
Authors: Ülgen Veronica S , Forslund Helena 
Published: January 2015

Purpose– The purpose of the paper is to explore the practices with logistics performance management in two textiles supply chains, and to identify the related best practices and barriers.Design/methodology/approach– The method is a multiple case study of two textiles supply chains with a special focus on the rarely addressed interface between the manufacturer and the retail chain. The retail chains represent one large, global retail chain and one Nordic, comparably smaller retail chain. This paper is primarily empirical and describes practices for logistics performance management. The analysis discusses and explains best practices and barriers for logistics performance managements in textiles supply chains.Findings– Differences were identified regarding practices, priorities and collaboration in the logistics performance management process. No textiles industry-specific practices were found. A way of exchanging action plans between the actors is an interesting best practice, which enables improvement projects even with long geographical distances. Barriers in the shape of difficulties in creating a collaborative culture were found; however, IT support seems no longer to be a barrier.Research limitations/implications– Two cases are explored, why a broader study is necessary to confirm the results. The best practices and barriers identified are similar to those known from manufacturing companies.Practical implications– The detailed descriptions of logistics performance management practices can provide insights for practitioners. Even if the studied supply chains are important for the respective actors, there is a potential for increased effectiveness in textiles supply chains.Originality/value– Supply chains for textiles products “starting at a manufacturer and ending in a retail chain” seem to be an unchartered territory and not many studies have been performed.
Designing a model for profiling organizational performance management
Authors: Jääskeläinen Aki , Roitto Juho-Matias 
Published: January 2015

Purpose
– The purpose of this paper is to design and test a model for analyzing organizational performance management (PM) practices.

Design/methodology/approach
– This study follows the design science approach. Variables affecting the status of PM are reviewed and classified based on existing literature. These variables are analyzed and a compact set of critical variables are chosen to represent PM maturity. Designed model is implemented in practice as a survey receiving 271 responses, and tested by using both quantitative and qualitative approach.

Findings
– The survey data are utilized in the development of four distinct PM maturity profiles. The empirical results provide understanding on the current PM maturity level and common development targets in Finnish organizations.

Research limitations/implications
– External validity of the research is compromised by the context and respondent group. More in-depth qualitative studies could provide more understanding on the causes of presented findings.

Practical implications
– The proposed model offers best practices to develop PM and identifies variables crucial to create satisfaction toward PM. The presented profiles also help in evaluating the status of PM in the organization examined.

Originality/value
– The originality of the new model relates to its balance between rigor and relevance. In addition, the study is one of the first attempts to widely apply PM maturity models in practice. A distinctive feature of this study is the maturity profiles which are built upon empirical data.
Study of reliability measures of a local area network via copula linguistics approach
Authors: Rawal D. K. , Ram Mangey , Singh V. V. 
Published: January 2015

Purpose
– The purpose of this paper is to find the reliability measures of Linux operating system connected in local area network (LAN).

Design/methodology/approach
– The system has two different topologies, i.e. star topology (subsystem-1) and bus topology (subsystem-2), are placed at two different places, and connected to a server through a hub. Both the topologies have n clients. The system has partial failure and complete failure. The partial failure is of two type’s namely minor partial and major partial. The minor partial failure degrades the system whereas the major partial failure brings the system to a break down mode. The system can completely fail due to failure of server hacking and blocking.

Findings
– By using supplementary variable technique and Laplace transformation, by taking different types of failure and two types of repairs the availability, non-availability, mean time to failure and cost analysis (expected profit) of the design system have been obtained.

Originality/value
– In this research, a mathematical model of Linux operating system has been discussed from which one can check the behavioral analysis of the designed system.
Using workplace changes as learning opportunities
Authors: Hetzner Stefanie , Heid Helmut , Gruber Hans 
Published: January 2015

Purpose
– This paper aims to contribute to an understanding of how individual characteristics and perceived contextual conditions shape reflection in professional work, particularly in workplaces that provide a variety of work experiences related to changes. The authors examine the effects of personal initiative, self-efficacy and perceived psychological safety in work relations with colleagues and supervisors on individuals’ reflection at work.

Design/methodology/approach
– A sample of 84 client advisors who had recently been affected by major changes in retail banking workplaces participated in the study. The participants completed a questionnaire consisting of instruments to map their self-rated personal initiative, self-efficacy beliefs, reflection at work and perception of psychological safety in work relations with colleagues and supervisors. The data were analysed by performing correlation analyses and hierarchical regression analyses.

Findings
– The results revealed that both individuals’ personal initiative and self-efficacy significantly positively affect reflection at work. An individual’s perception of psychological safety – particularly among peers – positively predicts reflection.

Originality/value
– This paper enriches the research on reflection in professional work, particularly against the backdrop of workplace changes. This is done by emphasising the power of individuals’ proactive role and initiative-taking work behaviour; positive beliefs in their own capabilities, e.g. managing the various opportunities involved in workplace changes; and their perception of a psychologically safe environment within a work group that is characterised by interpersonal trust, mutual respect and supportive cooperation.
Main difficulties hindering supply chain performance: an exploratory analysis at Uruguayan SMEs
Authors: Tanco Martin , Jurburg Daniel , Escuder Matias 
Published: January 2015

Purpose
– The purpose of this article is to create a list of supply chain (SC)-related difficulties based on the existing SC literature. It also presents an exploratory survey concerning the main difficulties which Uruguayan managers consider to have the most negative impact on their SCs.

Design/methodology/approach
– The survey was carried out within small- and medium-sized manufacturing and retailing companies in Uruguay, yielding 99 valid responses. A statistical analysis of the survey is introduced including a ranking of the difficulties and a grouping of those using factorial analysis. A difficulty, as understood throughout this paper, is any factor that significantly impacts, or has impacted in recent years, the performance of SCs.

Findings
– Eighteen main difficulties hindering SC performance were identified. Moreover, an exploratory analysis of the survey showed that the main concerns to SC managers are related to workforce availability and government policies.

Practical implications
– Difficulties encountered by SCs would not only be of interest to scholars but also to the managers who face the challenge of the day-to-day managing of a SC. Once the difficulties over the SCs are identified, strategies can be designed and implemented to attain desired benefits. Today’s intense competition requires firms to be more aware of their SC and to achieve excellence in many areas, especially at small- and medium-sized enterprises.

Originality/value
– There is a growing body of literature concerning isolated issues that SCs have to face; however, an exhaustive list of difficulties is hardly available. Moreover, first-hand information of Uruguayan managers was ascertained to rank each one using a Likert scale.

– Results show that 3.997 mg/m3 of hydrocarbon, 1.82 mg/m3 of NOx and 17.688 mg/m3 of carbon monoxide is emitted from the cars, trucks and buses, respectively, at Ashram intersection in one day. As there are 600 intersections throughout Delhi, a total of 2,398.055 mg/m3 of hydrocarbon, 1,087.068 mg/m3 of NOx and 10,612.612 mg/m3 of carbon monoxide is emitted from cars, trucks and buses in a day in all of Delhi.

Originality/value
– Knowledge of idling emission and fuel loss is very little for Indian traffic condition during delays.
Indoor air-quality investigation in code for sustainable homes and passivhaus dwellings
Authors: McGill Grainne , Oyedele Lukumon O. , Keeffe Greg 
Published: January 2015

Purpose– Energy efficient building design strategies are growing in popularity, promoted through increased awareness of climate change, rising energy prices, global consciousness and a demand for energy security. To aid this design process, assessment tools such as Code for Sustainable Homes (CSHs) and Passivhaus were introduced in the UK. However, it is suggested that these tools prioritise energy efficiency over occupant health through a fundamental lack of attention to indoor air quality (IAQ). The purpose of this paper is to investigate IAQ in selected dwellings built using CSHs level 6, level 3 and Passivhaus homes in the UK.Design/methodology/approach– Using a case study approach, the investigation consisted of IAQ measurements during summer and winter months, occupant diaries and occupant interviews.Findings– The results from the IAQ measurements show the recommended maximum level of 1,000 ppm was breached in all three Code 6 and two Code 3 homes, with levels slightly below this limit in the two Passivhaus homes. Measurements found high levels of formaldehyde, carbon dioxide and low levels of relative humidity.Practical implications– There is a need for the adequate consideration of IAQ in sustainable assessment methods, including the use of mandatory credits to ensure occupant health is not disregarded in the drive towards zero carbon.Originality/value– These results can be used to recognise areas of improvement in the CSHs and Passivhaus standard, and the design of energy efficient homes in general. Research of this nature is essential to ensure occupant health is not sacrificed through the drive towards zero carbon.

Authors: Idowu Michael Ayodele , Iroko Kazeem , Adeola Abiodun Aderoju , Oluwalana Isaac Babatunde , Ayo Jerome Ayokunle , Ikuomola Damilola Shayo 
Published: January 2015

Purpose
– The purpose of this paper is to evaluate some common bread improvers (normally used for 100 per cent wheat bread) for their effect on the quality attributes of wheat-cassava (90:10) composite bread.

Design/methodology/approach
– Four commonly used bread improvers (ASA, ABT, EDC and PTB) in Nigeria were evaluated for their effect on the baking potential of wheat-cassava (90:10) composite flour. Bread samples were baked from wheat-cassava (90:10) composite flour, with and without bread improvers. Changes in dough height during fermentation, oven spring, yield and specific volume of bread samples were determined. Bread samples were also evaluated for their sensory and staling characteristics.

Findings
– Results showed that dough height during fermentation did not change significantly (p<0.05) and crumb colour, firmness, taste and aroma were unaffected by addition of bread improvers; but oven spring, yield, specific volume, bread shape, crust colour, texture and overall acceptability of bread were significantly different (p>0.05). All the bread improvers except ABT extended the shelf life of wheat-cassava (90:10) composite bread for a period of 24-48 hours.

Practical implications
– Bread improvers normally used for 100 per cent wheat bread could be used effectively for wheat-cassava (90:10) composite bread without an adverse effect on quality of bread.

Originality/value
– Bread makers need little or no additional training to handle wheat-cassava (90:10) composite flour for bread making process hence, Nigeria can sustain her policy of using wheat-cassava composite flour for baking without any serious technical problem.
Diabetic nephropathy research in China: Data analysis and review from the National Natural Science Foundation of China中国糖尿病肾病研究现状：对中国国家自然科学基金数据的回顾性分析
Authors: Wan Qiang , Xu Yanying , Dong Erdan 
Published: January 2015

AbstractAs the largest funding agency of natural science of China, the National Natural Science Foundation of China (NSFC) has made great efforts in promoting the development of diabetic nephropathy (DN) research in recent years. The aim of the current study is to summarize the diabetic nephropathy research in China by analyzing NSFC‐funded projects.Data on all projects in the DN field funded by NSFC from 1986 to 2013 were collected. The funding tendency, funding areas, and hotspots in the DN field, and major research institutions, were analyzed. As one output of this support, outstanding research groups in China, and their representative studies, are also highlighted.From 1986 to 2013, the NSFC has funded a total of 248 projects in the DN field, with a total funding amount of 91.5 million RMB (US$14.9 million). A rapid increase could be seen in the past 5 years, with an average annual 30% increase in projects numbers and a 52% increase in funding amount. All fields in DN research have been covered by the NSFC, including etiology, pathophysiology, diagnostics, and therapeutics. Along with increased funding of the DN research, there has been a growth in the papers published in Science Citation Index journals by Chinese scholars.In the past decade, the funding scale and funding budget have increased dramatically. Benefiting from this, DN research in China has also made considerable progression.
