AbstractRecent studies suggested that nocturnal variations of blood pressure (BP) were closely related to type 2 diabetes. However, little information has been revealed about the relationship between reverse-dipper pattern of BP and type 2 diabetes. In this cross-sectional study, BP variations of 531 hypertensive patients were evaluated with ambulatory BP monitoring (ABPM). Diagnosis of diabetes in Chinese adults was made according to diabetes diagnostic criteria of 2015. Multivariate logistic regression was used to examine the relationships between type 2 diabetes and ABPM results. In the study, patients with reverse-dipper pattern (32.3%) had the highest prevalence of type 2 diabetes compared with dippers (21.4%) and nondippers (23.3%). After multivariate logistic regression, reverse-dipper BP pattern (OR 2.067, P = 0.024) and nondipper BP pattern (OR 1.637, P = 0.039) were found to be correlated with type 2 diabetes compared with dipper pattern. The results of our study also suggested that type 2 diabetes might contribute to the reverse-dipper pattern of BP (OR 1.691, P = 0.023). In addition, fasting glucose was negatively correlated with the decline rate of nocturnal SBP (r = -0.095, P = 0.029). Reverse-dipper pattern of BP in ABPM may be independently associated with type 2 diabetes in patients with hypertension.

Authors: Sung H.K. , Wang C. , Kim N.Y. 
Published: April 2016

A comparative analysis of the properties of vertical light‐emitting diodes (VLEDs) fabricated using different surface treatment schemes was conducted. Compared with a conventional VLED, a light output power increase of 24.8% for an injection current of 350 mA was achieved by an n‐type‐gallium nitride (GaN)‐based VLED with a thin undoped GaN layer and microsized protrusions produced by krypton fluoride laser irradiation using an energy density of 600 mJ/cm2. This was accomplished without noticeable degradation of the electrical properties of the device. Further, potassium hydroxide wet etching of the VLED surface increased the light output power gain to 47.3% for the same injection current.
Electrically small folded spherical helix antennas using copper strips and 3D printing technology
Authors: Kong M. , Shin G. , Lee S.‐H. , Yoon I.‐J 
Published: April 2016

Folded spherical helix (FSH) antennas using thin and wide copper strips instead of thick wires as a means of reducing the electrical size of ka is designed. It is found that FSH antennas made of copper strips show comparable radiation properties to FSH antennas made of thick wires. Furthermore, such designs can achieve even smaller size down to ka of 0.11 while keeping the radiation quality factors approaching the lower physical bound. An FSH antenna made of copper strips with ka of 0.21 is fabricated as a prototype using 3D printing technology. The measured resonance occurs at 307 MHz with the radiation efficiency of about 90%, verifying the simulated results and the proposed method of utilising copper strips in designing extremely small yet highly efficient volumetric folded helix antennas.

Published: April 2016

Background Concurrent pulmonary tuberculosis (TB) and lung cancer are rarely encountered in Western countries; however, it is more common in developing countries. We aim to share the diagnostic and treatment approaches in this study.
Materials and Methods Clinical files of all patients undergoing lung resection for non–small cell carcinoma with concurrent pulmonary TB between February 2006 and December 2012 were investigated retrospectively in terms of patient characteristics, operation methods, definite pathology and stage of tumor, postoperative treatment schemes, and associated complications.
Results TB was detected in 17 (1.3%) of 1,266 operated carcinoma patients. Eleven had squamous cell carcinoma and six had adenocarcinoma. Mean age was 54.9 years. Two patients received anti-TB treatment preoperatively. Fifteen patients were given anti-TB treatment postoperatively, as soon as definite microbiological confirmation was obtained, and concurrently given adjuvant therapy after 3 weeks of sole four-drug TB treatment. Pneumonectomy was performed in four (23.5%), sleeve lobectomy in three (17.6%), lobectomy in eight (47%), and bilobectomy in two (11.7%) patients. Postoperative complications occurred in four (23.5%) patients, with bronchopleural fistula being seen in only one pneumonectomy patient. No postoperative mortality or reactivation of TB was seen. Mean survival time was 32 ± 2 months.
Conclusion Resection following a 3-week anti-TB treatment or concurrent anti-TB and postoperative adjuvant chemotherapy does not constitute an additional postoperative risk for patients with concomitant lung malignancy and pulmonary TB. The determination of optimum treatment for these patients presents a challenge in developing countries, where TB is still a common disease.

Published: April 2016

Abstract
A bacterial strain (strain 224), which has the ability to utilize sulfanilic acid as a sole source of carbon, was isolated from soil. 16S rRNA gene sequence obtained from strain 224 exhibited 100% identical to that of species in the genus Bradyrhizobium. Strain 224 degraded 4.7 mM of sulfanilic acid and released almost the same molar concentration of sulfate ion
Activating the adoption of innovation: lessons from a passive house network
Authors: Mlecnik Erwin 
Published: April 2016

Purpose
– The purpose of this paper is to explore innovation adoption theory and to define a model to investigate operational activities and communication in innovation networks that can stimulate both supply and demand. It also aims to exemplify this model with the activities of an innovation network dedicated to promoting passive houses.

Design/methodology/approach
– Autoethnography and literature research were used to develop a model in order to conduct a structured analysis of operational activities and facilitate innovation-decision processes using networks. Data on the activities used to steer client decisions and businesses’ innovation were gathered from network archives and from the results of social research methods applied within a passive house network.

Findings
– The findings reveal that operational activities of multiplayer networks should focus on reinforcing conditions and communicative activities that support innovation-decision processes from one step to the next. In order to activate supply and demand, communication strategies can be modelled to increase the adoption of innovation and continued knowledge generation in networks.

Research limitations/implications
– Because only one network was evaluated and only the housing sector was exemplified, it may not be possible to generalise the research results. Researchers are therefore encouraged to test the proposed model further.

Practical implications
– The paper includes the implications of developing activities in innovation networks, in order to guide both businesses and customers through the steps of the adoption-decision process.

Social implications
– The paper provides insights regarding the uptake of innovation in the construction sector, beyond demonstration projects.

Originality/value
– This paper connects the innovation adoption to activities of a network in the field of construction.
Cultural competence – a success factor in NGO projects?
Authors: Dale Jorunn Marie , Dulaimi Mohammed Fadhil 
Published: April 2016

Purpose
– The purpose of this paper is to investigate the impact of cultural competence on the ability of project managers to lead international development projects successfully.

Design/methodology/approach
– An empirical qualitative research was applied and a case study approach was chosen. In this case, the researcher followed an international project manager amongst the Maasai people in Kenya for six weeks. In addition to field observations, this study conducted 12 in-debt interviews and arranged several informal focus groups to discuss observed issues cross-culturally.

Findings
– Findings indicate that the cultural competence supports a process that might increase the awareness and knowledge of contextual factors that can improve the project managers’ ability to establish relationships, communicate and approach challenges and opportunities more effectively.

Originality/value
– There is very little research on the issue of multi-culturalism in the non-government development project environment. The outcome of this research is expected to stimulate further interest in the subject and encourage far-reaching research, which can provide a reliable future guide for PM’s and other decision makers in international non-government development projects.
Towards supply chain maturity in construction
Authors: Broft Rafaella , Badi Sulafa M , Pryke Stephen 
Published: April 2016

Purpose
– Several studies have underlined the potential of supply chain management (SCM) in meeting the formidable challenges associated with fragmentation, adversarial relationships and insufficient customer focus in the delivery of construction projects. However, properly documented examples of successfully implemented SCM initiatives, particularly at the lower tiers of the supply chain, are scarce. The purpose of this paper is to extend the existing debates by adopting an alternative approach focusing specifically on the internal SCM organisation of both main contractor and subcontractor organisations, and their direct inter-relationships.

Design/methodology/approach
– This study sets out to explore the enablers and barriers to the implementation of SCM at the lower tiers of the construction supply chain, particularly the problematic collaboration between main contractors and subcontractors. SC maturity levels are formulated according to relevant SCM concepts and based on Holti et al.’s (2000) seven principles of SCM organisation, and transformed into a conceptual model. An explorative study is conducted based on interviews from eight large main contractor and subcontractor organisations in the Dutch construction industry.

Findings
– Discouragingly, across the organisations, more barriers than enablers to SCM are identified. Organisations are found to be particularly struggling to compete through superior value, manage costs collaboratively, and develop continuous improvement within their supply chains. The findings also underline the low SC maturity of main contractors and their inability to play the essential role of supply chain managers.

Practical implications
– The study underlines the need for a greater degree of main contractor leadership and improved internal organisation of both types of firms in order to achieve greater collaboration at the lower tiers of the construction supply chain.

Originality/value
– The study contributes to the subject of SCM in construction in two respects. First, the findings should prove valuable to both policy-makers and industry practitioners interested in the delivery of performance improvement in construction. Second, the developed SC maturity model can form the conceptual basis for the development of an applicable improvement framework towards successful SCM implementation.
Self-esteem and counterproductive work behaviors: a systematic review
Authors: Whelpley Christopher E. , McDaniel Michael A. 
Published: April 2016

Purpose– Consistency theory and ego-defense theory have been used to examine the relationship between counterproductive work behavior (CWB) and self-esteem; however, these two theoretical approaches pose different directions for the expected relation. In line with this, previous research concerning the relationship between self-esteem and CWB has found inconsistent empirical results. The purpose of this paper is to summarize the relation between self-esteem and counterproductive behavior at work and draw conclusions about the merit of the competing theories. This study also examines the type of self-esteem as a potential moderator to this relationship.Design/methodology/approach– The authors performed a psychometric meta-analysis of the relation between self-esteem and CWB using 21 correlations with a totalnof 5,135.Findings– The estimated population correlation was −0.26. The moderator analyses showed that global self-esteem had a stronger relation with CWB than organization-based self-esteem.Practical implications– The relation between self-esteem and counterproductive behavior at work is important to organizations for two reasons. First, CWBs are very costly at all levels of the organization. Second, organizations and managers have some control over the level of their employee’s self-esteem.Originality/value– Previous research has used both consistency theory and ego-defense theory to make predictions concerning the self-esteem and CWB relationship. This paper provides support for examining this relation using consistency theory due to the negative correlation the authors found between CWB and self-esteem.
Leader-follower congruence in loneliness, LMX and turnover intention
Authors: Chen Yushuai , Wen Zhonglin , Peng Jian , Liu Xiqin 
Published: April 2016

Purpose– Research on workplace loneliness has thus far been dominated by perceptions of followers; hence, few researchers have considered the perspective of leader-follower congruence. The purpose of this paper is to examine how the leader-follower relationship mediates the relationship between leader-follower congruence/incongruence in workplace loneliness and turnover intentions.Design/methodology/approach– Data were collected from 232 leader-follower dyads from ten companies in China. Polynomial regression combined with the response surface methodology was used to test the hypotheses.Findings– Four conclusions were drawn. First, leader-member exchange (LMX) was higher when leaders and followers were aligned in terms of workplace loneliness than otherwise. Second, in the case of leader-follower congruence, LMX rose as their workplace loneliness fell. Third, in the case of incongruence, followers had lower LMX when they were lonelier than their leaders. Finally, LMX partially mediated the leader-follower congruence/incongruence effect of workplace loneliness on followers’ turnover intention.Originality/value– This study emphasized the importance of leaders’ congruence with followers in workplace loneliness. Additionally, it extended research on leader-follower congruence from a positive perspective to a negative one.
Employees and sustainability: the role of incentives
Authors: Merriman Kimberly K , Sen Sagnika , Felo Andrew J , Litzky Barrie E 
Published: April 2016

Purpose– Organizational sustainability has become a priority on many corporate agendas. How to integrate sustainability efforts throughout the organization, however, remains a challenge. The purpose of this paper is to examine two factors that potentially enhance incentive effects on employee engagement in environmental objectives: explicit organizational values for sustainability and the performance objective’s complementarity with incented financial objectives.Design/methodology/approach– The authors employed a quasi-experimental design in which participants were randomly assigned to one of four conditions, including a status quo condition against which the treatments were contrasted. Participants (n=400) were comprised of a cross-section of US employees from a wide range of occupations and industries. Apost hocqualitative analysis provided additional insights.Findings– Incentive effects were enhanced (i.e. preference for the environmental objective was significantly higher) when the environmental project offered complementary benefits for financial objectives, but not when organization values emphasized sustainability. An entrenched status quo bias for financial performance was discerned among a subset of the sample.Research limitations/implications– Management scholars must pay close attention to the role of implicit norms for financial performance when investigating employee engagement in organizational sustainability efforts. From an applied perspective, framing sustainability objectives to emphasize financial benefits consistent with a financial mission may maximize employee engagement.Originality/value– This study contributes to understanding of organizational sustainability efforts at the individual employee level of analysis, a conspicuously small part of the organizational research surrounding this topic.
The work engagement grid: predicting engagement from two core dimensions
Authors: Costa Patrícia Lopes , Passos Ana Margarida , Bakker Arnold B. 
Published: April 2016

Purpose
– The purpose of this paper is to test whether work engagement can be predicted by two core dimensions, energy and involvement, both at the individual and team levels.

Design/methodology/approach
– Based on the circumplex model of affective well-being (Russell, 1980), the authors propose the work engagement grid and collect data on individual and team work engagement (TWE) from two different samples (n=1,192 individuals).

Findings
– Results show a significant positive relationship between the individual engagement grid and individual work engagement. However, only the energy dimension significantly predicted TWE. The authors also provide evidences for the relationship between the engagement grid and related variables (e.g. adaptive performance, team cohesion, satisfaction), and show that the combination of energy and involvement present smaller correlations with those variables than the complete engagement scales.

Research limitations/implications
– Data were collected from simulation samples, therefore generalization of the findings must be done with caution. The findings allow for developing a brief measure of work engagement, particularly useful for longitudinal or diary study designs.

Practical implications
– When teams are the work unit, the displays of energetic behaviors ought to be fostered in order to boost collective engagement.

Originality/value
– The authors add to the existing literature on work engagement, concluding that individual and team-level work engagement have structural differences between them, with the collective construct being dependent on external manifestations of energy, and that individual work engagement needs a cognitive component of absorption in order to foster performance.
Organizational transformation through improved employee engagement – “How to use effective methodologies to improve business productivity and expand market share”
Authors: Daneshgari Perry , Moore Heather 
Published: April 2016

Purpose
The purpose of this paper is to help businesses understand that as markets change, the way a company does business also must change to stay competitive in their industry. A company needs to know their share of the market to develop strategies to stay competitive and survive. This case study takes you through a successful company’s recognition and transformation involving all aspects of the organization. Cross-functional teams were developed to improve existing processes and develop new ones, as well as educate their people along the way.

Design/methodology/approach
The case study explains the process taken to help the company make the required changes to stay competitive. The company’s transformation happened through the application of Agile Construction® and the implementation of design teams to develop and test new or improved company processes and procedures. Once the improvements proved successful, the new standardized way of doing business was introduced to the rest of the organization. Tools were introduced to enhance the new processes and make them visible to the entire organization.

Findings
It was found that working together as a team and learning together to create standardized processes improved the company’s overall profitability, increased sales and expanded their market share. It takes a lot of dedication and hard work along the way to improve. The process also proved that the team has to work toward the same goals for the transformation to be successful.

Practical implications
Changes to practice that must be made is that communication is key among everyone involved in the organization. Also, there is value in understanding that the organization’s way of thinking needs to change to a learning organization.

Originality/value
Any organization, whether a company or an institution, can benefit from reading this case study. It is important to understand that the way of doing work changes over time and improvements have to be made to be successful in any industry. Team work is also important, so that everyone is reaching for a common goal.
Effects of sulphate salts on concrete with untreated coal fly ash (CFA) as partial cement replacement
Authors: Coopamootoo Kumaran , Rughooputh Reshma 
Published: April 2016

Purpose
– The cementitious/chemical properties of the untreated CFA are dependent on the coal composition and previous burning conditions. The purpose of this paper is to investigate whether untreated CFA can efficiently reduce cement replacement and does not require further combustion treatment to be a viable cement replacement.

Design/methodology/approach
– Two types of mixes: Type I concrete and PCFA (Type I and 30 per cent untreated CFA) concrete were batched and subjected to compressive strength tests and cyclic exposures of 5 per cent sodium sulphate (Na2SO4) and 5 per cent magnesium sulphate (MgSO4), respectively.

Findings
– PCFA mix was 41.1 and 35.21 per cent lower in strength compared to Type I at 28 and 56 days correspondingly. Continuous-sulphate-exposure resulted in slow but continued strength development for both mixes. However, the strengths of PCFA cubes exposed to cyclic sulphate and sulphate/magnesium salts continued to increase at a lower rate from their corresponding 28-day strength (rate of 18.7 per cent and strength 27.30 MPa in Na2SO4 and rate of 10.0 per cent and strength 25.30 MPa in MgSO4) while Type I specimens subjected to the same exposure conditions experienced drastic reductions in strength (rate of −15.0 per cent and strength 33.21 MPa in Na2SO4 and rate of −23.4 per cent and strength 29.94 MPa in MgSO4).

Research limitations/implications
– Results justify the need for additional tests essentially: at different percentage replacement of untreated CFA, fineness of materials, chloride environment and longer exposures, to address the cementitious properties of untreated CFA as cement replacement.

Originality/value
– Treatment methods for fly ashes require undoubtedly additional resources, energy input and cost. This paper paves the way to define whether untreated CFA can be used as cement replacement in concrete.
