N-cetyl-N,N,N trimethyl ammonium bromide (CTAB)-stabilized polyaniline: a corrosion inhibitor for mild steel
Authors: Rashid Mohd , Waware Umesh S. , A. Rahim Afidah , Hamouda A.M.S. 
Published: March 2018

Purpose
The purpose of this study is to compare the inhibitive effect of polyaniline (PAni) and N-cetyl-N,N,N trimethyl ammonium bromide (CTAB)-stabilized PAni in a hydrochloric acid (HCl) medium.

Design/methodology/approach
PAni has been deposited potentiodynamically on mild steel in the presence of CTAB as a stabilizing agent to achieve high corrosion inhibition performance by the polymer deposition. The corrosion inhibition studies of CTAB-stabilized PAni inhibitor in 0.1 M HCl acidic solution was carried out by electrochemical methods, namely, open-circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopy technique.

Findings
The results of electrochemical studies have shown that the CTAB-stabilized PAni inhibitor has higher corrosion efficiency than PAni on mild steel in 0.1 M HCl solution. The maximum per cent efficiency evaluated using the potentiodynamic polarization method is approximately 91.9.

Originality/value
CTAB-stabilized PAni has never been studied as a corrosion inhibitor for mild steel in an acidic medium. The investigations demonstrate relatively the better corrosion inhibition efficiency and high dispersion of the polymer in the acidic medium.
Linking authoritarian leadership to employee creativity
Authors: Gu Jibao , Wang Gang , Liu Hefu , Song Derun , He Changqing 
Published: March 2018

PurposeThe present study aims to examine how and when authoritarian leadership affects employee creativity. Based on social exchange theory and team identification literature, the present research attempts to simultaneously explore how leader–member exchange (LMX) and team identification serve as two important mediating processes in the relationship between authoritarian leadership and employee creativity. Furthermore, this research uncovers the mechanism under which conditions the effects of authoritarian leadership will be magnified or minimized.Design/methodology/approachA survey has been conducted in China by using a questionnaire to collect data. The study sample consisted of 325 employees. LISREL 8.7 and SPSS 18.0 were used to test the mediating and moderating effects, respectively.FindingsResults from 325 employees revealed that both LMX and team identification mediated the negative relationships between authoritarian leadership and employee creativity. Specifically, the relationship between two mediators was that LMX was positively related to team identification. In addition, the relationship between authoritarian leaderships and LMX and team identification was moderated by power distance, such that the negative relationships will be weaker with high power distance and stronger with low power distance.Practical implicationsFirst, firms and managers should recognize and take actions to reduce the negative effects of authoritarian leadership, such as effective selection system and interventional mechanisms because authoritarian leadership is important in influencing employee creativity. Second, managers are suggested to take specific actions, such as increasing communications and team-building activities, to promote LMX and team identification, thereby enhancing employee creativity. Third, managers should engage in behaviors that motivate employee creativity, such as empowerment behaviors, other than authoritarian leadership, when the employee has low power distance.Originality/valueThe primary contribution of this research is that two psychological processes (i.e. LMX and team identification) have been identified through which authoritarian leadership is related to employee creativity. Meanwhile, this study explores the relationship between LMX and team identification. Moreover, the current research deepens our understanding of power distance by empirically examining the moderating effect of power distance. Overall, the findings extend our understanding about the relationship between authoritarian leadership and employee creativity and contribute to literature on authoritarian leadership and creativity.
Localising climate change: heatwave responses in urban households
Authors: Cornes Isabel Clare , Cook Brian 
Published: March 2018

Purpose
The purpose of this paper is to provide empirical insights into urban household perceptions and (in)action towards the perceived impacts of climate change, based on a case study in Kensington, Victoria, Australia. This case utilises households as sites of active agency, rather than as passive recipients of climate change or associated governance.

Design/methodology/approach
This research trialled an approach to engaging a community in the context of disaster risk reduction (DRR). It involved a two-stage quantitative door-knocking survey (reported elsewhere), followed by a qualitative interview with interested households. In total, 76 quantitative surveys contextualise 15 qualitative interviews, which are the focus of this analysis. The findings are presented comparatively alongside the current literature.

Findings
Heatwaves are understood to be the most concerning hazard for the households in this sample who associate their increasing frequency and severity with climate change. However, subsequent (in)action is shown to be situated within the complexities of day-to-day activities and concerns. While respondents did not consider themselves to have “expert” knowledge on climate change, or consider their actions to be a direct response to climate change, most had undertaken actions resulting from experience with heatwaves. These findings suggest there may be an under-representation of DRR, which includes climate change adaptation actions, within the existing research.

Research limitations/implications
While this sample justifies the arguments and conclusions, it is not a representative sample and therefore requires follow-up. It does however challenge traditional approaches to risk management, which focus on awareness raising and education. The research highlights the unique contexts in which households perceive and act on risk, and the need for risk “experts” to consider such contexts.

Originality/value
This research provides empirical evidence of urban household responses to perceived climate change-related risk, an often-neglected dimension of heatwave and adaptation studies in Australia. The findings also suggest promise for the methodological approach.
Orientation measurement of graphically simulated nanoscale electrospun fibrous structures using particle-based modeling and 2-D metaball fitting
Authors: Moon Sun Hee , Hong Kyung Hwa , Lee Jaewoong , Sul In Hwan 
Published: March 2018

Purpose
The purpose of this paper is to provide an efficient tool for simulating electrospinning process in virtual 3D space and optimizing experimental parameters. The fiber orientation from virtual or real electrospinning process can be easily measured using the image analysis technique. Using the semi-implicit Euler integration, the time integration can be more fast and stable, which enabled optimization of the electrospinning process. Also boundary conditions can be easily adopted during conjugate gradient matrix solving step.

Design/methodology/approach
To simulate the electrospinning process, the authors have adopted a particle-based modeling technique using the molecular dynamics theory, which is known to be suitable for modeling materials with nonlinear and nonhomogeneous behavior such as fibers or fabrics. Gravitational, tensional, and electrostatical forces and their Jacobians were carefully defined and chosen to maintain the stability of the governing equation. Preconditioned conjugate gradient method was used to solve the matrix iteratively with boundary conditions. The 2-D metaball fitting technique, which was applied in the previous research (Sul et al., 2009) on experimental nanofiber scanning electron microscopy images, was utilized with virtual nanofiber images. A staircase function and a new shading language were proposed to automatically calculate the orientation and radius distribution of the graphically simulated electrospun fiber structures. The automatic measurement procedure was verified via graphically designed virtual replica images. Also the orientation tendency acquired from the simulation was compared with that of experimental data.

Findings
Simulation result of fiber orientation showed linear relationship with the collecting drum speed. Use of particle-based method generated a simple system to simulate electrospinning process.

Originality/value
The semi-implicit Euler integration was applied to the electrospinning process and the final linear system was numerically stable to solve.
Approaches to the design of refugee camps
Authors: Jahre Marianne , Kembro Joakim , Adjahossou Anicet , Altay Nezih 
Published: March 2018

Purpose
An unprecedented scale of human migration has lead humanitarians to view camps as long-term settlements rather than temporary holding facilities. The purpose of this paper is to increase the understanding of and identify challenges with this proposed new approach to camp design.

Design/methodology/approach
Based on the camp design literature, the authors developed an interview guide and checklist for data collection. A multi-site case study and within- and cross-case analysis was then conducted.

Findings
The findings suggest that the proposed new approach is implemented only to a limited extent, and mostly in a stepwise manner. As camps mature, there is a shift toward the new approach, but most camps are established using the traditional top-down, temporary, and isolated approach.

Research limitations/implications
The findings are based on four camps in four different countries and do not provide an exhaustive global coverage.

Practical implications
The insights the authors derived and the challenges identified from the empirical evidence can be used to better plan future camps.

Social implications
The results can support improvements in camp design, thus alleviating suffering for both refugees and host communities, particularly in developing countries. In particular, the trade-off between a permanent solution and the temporary must be accounted for.

Originality/value
The study contributes to the literature by developing and proposing a conceptual framework to camp design. The cross-case analysis provides an initial understanding and categorization of challenges with implementing the new approach. It also suggests an evolutionary perspective of camp design.
Shared leadership as a vehicle to healthy service eco-systems: practical or fanciful?
Authors: Johansson Clare , Bedggood Rowan , Farquharson Karen , Perenyi Aron 
Published: March 2018

PurposeThe purpose of this paper is to determine whether a shared leadership governance arrangement facilitates improved outcomes within a social marketing service eco-system. The research was focussed on gaining an understanding of participants involved in a cross-institutional partnership. The case study selected to facilitate this exploration was a social marketing project that aimed to support aboriginal households in Victoria with regard to their energy efficiency. It thus investigated the meso-level insights experienced by partners and those delivering the service.Design/methodology/approachInterview (yarn-based) data from 20 individuals involved in an energy efficiency programme were collected and analysed. Participants shared their experiences via informal “yarns” that were conducted in the first 12 months of the programme. This timing was chosen to gain their initial self-reflective perspectives and their interactions within the shared leadership model.FindingsThe results of the analysis identified six key themes that are interrelated and fundamental to building trust between all actors involved. The themes include relationship building, advocating rights, managing competing priorities, being community driven, using communication that translates and using community networks. Four of the themes were found to be components of relationship and trust building, which collectively lead to effectively accessing aboriginal communities. These findings extend current knowledge on the structures necessary to ensure healthy eco-systems are sustained throughout social marketing programmes.Research limitations/implicationsThe authors established that shared leadership is well aligned with service-dominant logic, and the findings of this study reveal that it can positively contribute to meso-level service eco-systems and thus improve social outcomes for recipients of social marketing efforts. The findings also underscore the need for social marketers to recognise the importance of having a culturally acceptable value co-creation model in social marketing programmes when working with Aboriginal Australians.Originality/valueThis paper is the first to explore and develop the authors’ understanding of the efficacy of adopting a shared leadership approach in social marketing. Shared leadership has the potential to be an institutional arrangement that facilitates service-dominant logic and the value co-creation process, influencing positive behaviour change at the micro level in aboriginal communities. Specifically, it is the first to identify that “advocating rights” is an important component for partners to adopt in cross-cultural collaborations when collectively running social marketing programmes.
General principles of systems
Authors: Korn Janos 
Published: March 2018

Purpose
Three problematic issues followed by paradigm changes over the recent history of human intellectual endeavour are identified as 1. mysticism/superstition to – conventional science (of physics), 2. predominant use of qualitative/quantitative properties for analysis and design to – structural or systemic properties, and 3. current speculative/fragmented, multiple approaches to the “systemic view” to – a firmer knowledge-based approach reflecting the empirical and universal nature of this view. This paper aims to consider the problematic issues, to conclude that conventional science is inadequate to cope with the 2nd paradigm change and to introduce a “new science of systems” which can integrate conventional science and alleviate the 3rd problematic issue by suggesting three principles implemented by linguistic modelling as operational model.

Design/methodology/approach
The highly successful methodology of conventional science is followed with systemic content by suggesting three general principles of systems, namely, principle of existence (pervasiveness of structural description), principle of complexity (aggregates for emergence of outcomes) and principle of change (change by purpose or chance), and linguistic modelling of static and dynamic scenarios based on natural language as operational model. This language is processed to “elementary constituents”, of which complex structures can be constructed. These constituents are converted into reasoning schemes consisting of “ordered pairs” and “predicate logic statements” in static and dynamic states.

Findings
Stories of problematic scenarios are converted into the universal scheme of “management/producers” – “products” – “users/consumers” by constructing linguistic networks of products and semantic diagrams of organizations/user/consumers for investigating the emergence of outcomes in analysis and for designing prototypes. Problematic issues of individual objects in a scenario are resolved by methods of conventional science, which is thus integrated with systems science to form the “scientific enterprise”.

Research limitations/implications
Once the new approach is debated, further developments in the mathematics of ordered pairs, predicate logic and uncertainties are needed. The linguistic basis is to be further investigated. Connection with AI and “logical atomism of Bertrand Russell” is to be explored.

Practical implications
Further applications to large-scale scenarios by practitioners using the “universal scheme” and development of software are needed.

Social implications
The approach is rooted in accepted branches of knowledge, is highly teachable and should lead to be used by professionals and others once debated and accepted.
Malignant atrophic papulosis with motor aphasia and intestinal perforation: A case report and review of published works
Authors: Hu Pan , Mao Zhi , Liu Chao , Hu Xin , Kang Hongjun , Zhou Feihu 
Published: March 2018

AbstractMalignant atrophic papulosis (MAP) is a rare type of obliterating vasculopathy that can present as pure cutaneous lesions or a systemic entity affecting multiple organs. Systemic disease, such as gastrointestinal or central nervous system involvement, may predispose the patients to poorer or even fatal outcomes. We present a 30‐year‐old female patient with systemic manifestation of MAP 10 days after delivery of a full‐term pregnancy who subsequently developed motor aphasia and intestinal perforation. The patient was administrated empirical treatment with an antiplatelet, anticoagulant, methylprednisolone sodium succinate and alprostadil. Antibiotics were administrated due to intestinal perforation and secondary sepsis. Despite all treatment, the patient died a week later. We summarized all the previous reports of MAP based on thorough review of previous published work. Overall, this is the first patient with MAP combined with motor aphasia and intestinal perforation and may provide insights for future studies on the treatment of this disease.
China's Abolition of the Agricultural Tax, Local Governments’ Responses and Economic Growth
Authors: Shi Hao , Ye Bing 
Published: March 2018

AbstractWhen evaluating agricultural policy changes, much of the attention in the literature has been limited to agricultural productivity growth. This study demonstrates that, under a regionally decentralised authority system, the effect of China's abolition of the agricultural tax (AAT) in 2004–05 extended beyond the realm of agriculture. We find that, following the AAT reform, Chinese counties with higher reliance on agricultural taxation for budgetary revenue prior to the AAT reform experienced higher agricultural economic growth, as expected, but lower non‐agricultural economic growth in the short run. This growth‐inhibiting effect of the AAT reform on non‐agricultural production in the short run can be explained, to some extent, by the increased non‐agricultural taxation due to the insufficient funds that Chinese county governments received from the upper‐level governments following the AAT reform; the magnitude of this tax increase was associated with the degree to which each county relied on agricultural taxation for budgetary revenue prior to the reform. In addition, our results show that the AAT reform resulted in a high level of regional inequality in terms of non‐agricultural GDP per capita. In summary, our study shows that although the AAT reform succeeded in promoting agricultural production, such accomplishments were achieved at the cost of lower non‐agricultural output growth and higher regional inequality of non‐agricultural GDP per capita at the county level.
Frequency of Dermatologic Findings at Autopsy
Authors: Cocks Margaret , Sander Inbal , Crain Barbara 
Published: March 2018

AbstractA complete academic autopsy includes an external examination with inspection of gross dermatologic findings. At our institution, the postmortem examination also includes a standard skin biopsy. We determined the microscopic yield of this standard postmortem skin biopsy and the overall frequency of macroscopic dermatologic diagnoses. We reviewed 389 complete autopsies conducted between 2012 and 2014. Both microscopic and macroscopic dermatologic diagnoses were analyzed. A macroscopic dermatologic diagnosis was made in 32% of cases while a microscopic diagnosis was recorded in 10% of cases. Dermatologic diagnoses were identified as leading directly to cause of death in 4% of patients and as contributing to death in another 20%. Targeted biopsies were more likely to reveal histologic abnormalities than routine biopsies from a standard anatomic site. Better training in skin gross examination in addition to systematic sampling of both skin lesions and grossly normal skin may improve diagnostic accuracy and enhance clinical pathologic correlations.
Line managers and HRM: A managerial discretion perspective
Authors: López‐Cotarelo Juan 
Published: March 2018

AbstractLine managers play a central role in HRM practices, but research and theory on how their role is enacted remains underdeveloped. This paper presents a case study of a large U.K.‐based fashion retailer and uses managerial discretion theory to develop a novel understanding of line managers' contribution to the implementation of HRM practices. We describe three distinct ways in which line managers engage with HRM policies and procedures, and propose that line managers make an important contribution to the effective implementation of HRM systems through exerting their cognitive and political abilities to bring about decisions that are well suited to their local situations. Moreover, we find that HR specialists design and manage HRM policies and procedures to afford different levels of managerial discretion in different areas of HRM.
Operating cash flow asymmetric timeliness in Australia
Authors: Lu Meiting , Shan Yaowen , Wright Sue , Yu Yimeng 
Published: March 2018

AbstractOperating cash flow (CFO) asymmetric timeliness occurs when CFO reflects bad news more quickly than good news. We examine the presence and determinants of CFO asymmetric timeliness in Australia, where substantial differences in reporting requirements of cash flow components, in characteristics of listed companies and in the degree of conservative financial reporting produce contrasting findings to those in the United States. We find supportive evidence for the novel ‘sticky cost behaviour’ explanation and also the product‐pricing strategy, but not the life cycle hypothesis. These findings are useful for investors and analysts concerned with forecasting the future values of companies.
