Published: September 2017

PurposeThe purpose of this paper is to establish a conceptual model adopted from a strategy-structure-performance paradigm for investigating the fit between the supply chain integration and halal food supply chain integrity and the impact of halal food supply chain integrity on firms’ performance in a Malaysian context.Design/methodology/approachThis study comprises a sample of a halal manufacturing firm in Malaysia. A cross-sectional research design was used in this study. Data were gathered based on mailed and personally administered questionnaires. SmartPLS was used to analyse the 254 valid responses.FindingsThe research findings indicate that internal integration and strategy have positive impact on halal food supply chain integrity. The study results confirmed that customer integration and supplier integration contributes to halal food supply chain integrity. It also finds that halal food supply chain integrity has a significantly positive impact.Research limitations/implicationsThe results suggested that a strategic collaboration with the supplier pivoted around the quality and integrity of the raw materials should be undertaken.Practical implicationsThe results from this study supports that the managers should adopt all halal food supply chain integrity components to achieve a superior performance. Even though some of the components did not yield significant results in terms of their relationships with firms’ performance, these dimensions were generally related to the standardised industry requirements, such as certifications.Originality/valueThe findings are original and unique and are based on established theories from the literature on supply chain management practices. The research findings are useful to academics and policymakers interested in fostering a halal supply chain in Malaysia.
The effect of technology innovation on mobile communication and mobile products
Authors: Lee Eui-Bang 
Published: September 2017

Purpose
In order to understand the influence of technology innovation on market demand diffusion in the ICT service market, the purpose of this paper is to examine technology innovation in the mobile product market, which keeps a complementary relationship with the mobile communication market.

Design/methodology/approach
This study collected mobile communication user information of four leading countries in the ICT market – the USA, the UK, Korea, and Japan from 1981 to 2014. This study applies the Bass diffusion model to analyze the form of market demand diffusion and conducts white noise test to verify the hypotheses.

Findings
Technology innovation of mobile communication leads to an increase in innovation effect and a decrease in imitation effect. Thus, technology innovation of mobile communication needs to be promoted continuously for the purpose of increasing adopters in the early stage. Besides, mobile product’s technology innovation leads to an increase in imitation effect and a decrease in innovation effect, because individuals were aware of the usefulness of the products and services. Hence, the increase in the number of imitators caused a higher increase in imitation effect than in the mobile communication’s innovation effect.

Originality/value
Based on the results of this study, the role that product and service technology innovation plays in renewing the form of market demand diffusion in the ICT service market was defined. Also, since the strategies and plans to acquire competitive advantage of business were understood, it may help both companies and policy decision makers.
Heritage values and legal rules
Authors: Wells Jeremy C. , Lixinski Lucas 
Published: September 2017

Purpose
Existing regulatory frameworks for identifying and treating historic buildings and places reflect deference to expert rule, which privileges the values of a small number of heritage experts over the values of the majority of people who visit, work, and reside in historic environments. The purpose of this paper is to explore a fundamental shift in how US federal and local preservation laws address built heritage by suggesting a dynamic, adaptive regulatory framework that incorporates heterodox approaches to heritage and therefore is capable of accommodating contemporary sociocultural values.

Design/methodology/approach
The overall approach used is a comparative literature review from the fields of heterodox/orthodox heritage, heterodox/orthodox law, adaptive management, and participatory methods to inform the creation of a dynamic, adaptive regulatory framework.

Findings
Tools such as dialogical democracy and participatory action research are sufficiently pragmatic in implementation to envision how an adaptive regulatory framework could be implemented. This new framework would likely require heterodox definitions of law that move beyond justice as a primary purpose and broaden the nature of legal goods that can be protected while addressing discourses of power to benefit a larger group of stakeholders.

Practical implications
The authors suggest that an adaptive regulatory framework would be particularly beneficial for architectural and urban conservation planning, as it foregrounds considerations other than property rights in decision-making processes. While such a goal appears to be theoretically possible, the challenge will be to translate the theory of an adaptive regulatory framework into practice as there does not appear to be any precedent for its implementation. There will be issues with the need for increased resources to implement this framework.

Originality/value
To date, there have been few, if any, attempts to address critical heritage studies theory in the context of the regulatory environment. This paper appears to be the first such investigation in the literature.
Factors influencing control charts usage of operational measures
Authors: Ericson Öberg Anna , Hammersberg Peter , Fundin Anders 
Published: September 2017

Purpose
The purpose of this paper is to identify factors influencing implementation of control charts on key performance indicators (KPIs).

Design/methodology/approach
Factors driving organizational change described in literature are analyzed inspired by the affinity-interrelationship method. A holistic multiple-case design is used to conduct six workshops to affect the usage of control charts on KPIs at a global company in the automotive industry. The theoretical factors are compared with the result from the case study.

Findings
The important factors for implementation success differ to some extent between the theoretical and empirical studies. High-level commitment and a clear definition of the goal of change could be most important when creating a motivation for change. Thereafter, having a dedicated change agent, choosing an important KPI and being able to describe the gain in financial terms becomes more important.

Practical implications
By using control charts on KPIs, the organization in the case study has become more proactive, addressing the right issues upstream in the process, in the right way, cross-functionally.

Originality/value
Factors affecting the implementation of already available solutions in the industry are highlighted. This potentially provides a basis for improved decision making, which has a significant value.
PCA-spectroscopy study of common salt effect on solubility of direct dye
Authors: Shams-Nateri A. , Dehnavi E. , Zahedi E. 
Published: September 2017

Purpose
This work aims to explain the effect of common salt on absorbance spectra and solubility of textile direct dyes, which is important in analysing and reusing wastewater of dyeing process.

Design/methodology/approach
Several textile dyes such as Direct red 243, Direct yellow 86 and Direct blue 201 solutions with and without NaCl salt were used to study the effect of common salt on solubility of textile direct dyes. Several methods such as derivative spectrophotometry, principal component analysis and colorimetric techniques were used to analyse the absorbance spectra of dye solution.

Findings
The obtained results indicate that the effect of common salt on absorbance spectra and solubility of textile direct dye depends on the chemical structure of dyes. The NaCl salt significantly affects the solubility of Direct red 243 (red dye) and Direct yellow 86 (yellow dye) which have Azo compounds containing four SO3 functional groups. But the NaCl salt does not change the solubility of Direct blue 201 (Blue dye) which has Azo compound containing two SO3 functional groups. Also, the NaCl salt decreases the accuracy of dye concentration prediction.

Practical implications
During reusing wastewater of dyeing process, the amount of dyes has been evaluated via absorbance spectra of dye solution.

Originality/value
This work explains the effect of common salt on solubility of textile direct dyes and the accuracy of dyes concentration prediction.

AbstractIn hemodialysis patients the principal cause of arteriovenous fistula dysfunction is stenosis. Matrix‐metalloproteinase‐2 is implicated in the pathophysiological mechanism of stenosis development. Our study tried to assess the clinical impact of this protease on arteriovenous fistula survival. Seventy‐nine prevalent dialysis patients with functional arteriovenous fistulas were included in the study. The presence of stenosis and the serum levels of matrix‐metalloproteinase‐2 were determined at the beginning of the study. The patency of the arteriovenous fistulas was followed‐ up for two years. In multivariate regression; matrix‐metalloproteinase‐2 was a significant predictor of vascular access loss (HR = 1.104, 95%CI 1.033–1.179, P = 0.003). Patients with a level of matrix‐metalloproteinase‐2 lower than 50 ng/mL had a better survival of the arteriovenous fistulas. Matrix‐metalloproteinase‐2 was an even stronger predictor of fistula failure in the stenosis group (HR = 1.076, 95%CI 1.027–1.127, P = 0.002). In our study matrix‐metalloproteinase‐2 has a predictive value for arteriovenous fistula failure.
Quinoa Starch Characteristics and Their Correlations with the Texture Profile Analysis (TPA) of Cooked Quinoa
Authors: Wu Geyang , Morris Craig F. , Murphy Kevin M. 
Published: September 2017

AbstractStarch characteristics significantly influence the functionality and end‐use quality of cereals and pseudo‐cereals. This study examined the composition and properties of starch from 11 pure varieties and 2 commercial samples of quinoa in relationship to the texture of cooked quinoa. Nearly all starch properties and characteristics differed among these samples. Results showed that total starch content of seeds ranged from 53.2 to 75.1 g/100 g apparent amylose content ranged from 2.7% to 16.9%; total amylose ranged from 4.7% to 17.3%; and the degree of amylose–lipid complex ranged from 3.4% to 43.3%. Amylose leaching ranged from 31 mg/100 g starch in “Japanese Strain” to 862 mg/100 g starch in “49ALC.” “Japanese Strain” starch also exhibited the highest water solubility (4.5%) and the lowest swelling power (17). α‐Amylase activity in “1ESP,” “Col.#6197,” “Japanese Strain,” “QQ63,” “Yellow Commercial,” and “Red Commercial” (0.03 to 0.09 CU) were significantly lower than the levels of the other quinoa samples (0.20 to 1.16 CU). Additionally, gel texture, thermal properties, and pasting properties of quinoa starches were investigated. Lastly, correlation analysis showed that the quinoa samples with higher amylose content tended to yield harder, stickier, more cohesive, more gummy, and more chewy texture after cooking. A higher degree of amylose–lipid complex and amylose leaching were associated with softer and less chewy cooked quinoa TPA texture. Higher starch enthalpy correlated with firmer, more adhesive, more cohesive, and chewier texture. In sum, starch plays a significant role in the texture of cooked quinoa.Practical ApplicationThe research determined starch characteristics among a diverse set of pure quinoa varieties and commercial samples, and identified the relationships between starch properties and cooked quinoa texture. The results can help breeders and food manufacturers to understand better the relationships among quinoa starch characteristics, cooked quinoa texture, and the best use of different cultivars.
Awareness of SEC Enforcement and Auditor Reporting Decisions
Authors: Defond Mark L. , Francis Jere R. , Hallman Nicholas J. 
Published: September 2017

AbstractWe find that non‐Big 4 audit offices with greater awareness of SEC enforcement are more likely to issue first‐time going‐concern reports to distressed clients; where SEC “awareness” is measured using (i) audit office proximity to SEC regional offices, and (ii) proximity to specific SEC enforcement actions against auditors. We also show that these non‐Big 4 audit offices issue more going‐concern opinions to clients who do not subsequently fail, indicating a conservative bias that reduces the informativeness of audit reports. This conservative reporting bias is also associated with higher audit fees and higher auditor switching rates. These findings are important because non‐Big 4 firms now audit 39 percent of SEC registrants and issue 88 percent of going‐concern audit reports. For Big 4 offices, we find some evidence that awareness of SEC enforcement may improve reporting accuracy by reducing Type II errors (failing to issue a going‐concern report to a company that fails), although the number of cases is small.
A framework for high‐throughput eco‐evolutionary simulations integrating multilocus forward‐time population genetics and community ecology
Authors: Okamoto Kenichi W. , Amarasekare Priyanga 
Published: September 2017

Abstract

The evolutionary dynamics of quantitative traits in a species depends on demographic structure (e.g. age‐ and size‐dependent vital rates, migration across subpopulations, mate preferences, and the presence or absence of overlapping generations), which in turn can depend on interspecific interactions with other evolving species. Furthermore, biologists increasingly appreciate that evolutionary change in a single species can substantively affect broader ecological processes, such as community assembly and ecosystem functioning.

Models integrating insights from classical population and quantitative genetics, on the one hand, and community ecology theory, on the other, are therefore critical to elucidating the interplay between ecological and evolutionary processes. However, few modelling approaches integrate ecological and genetic details into a comprehensive framework. Such models are needed to account for the reciprocal feedback between evolutionary change and ecological dynamics, and develop effective responses to anthropogenic disturbances on natural communities, improve agricultural practices and manage global health risks such as emerging pathogens.

Here we introduce an open‐source, multi‐species forward‐time population genetics simulator and framework for rapidly simulating eco‐evolutionary dynamics. Our approach permits building models that can account for alternative genetic architectures, non‐standard population dynamics and demographic structures, including those driven by interspecific interactions with other evolving species and the spatial dynamics of metacommunities. By integrating these processes into a common framework, we aim to facilitate the development of models that can further elucidate eco‐evolutionary dynamics.

While multi‐species, forward‐time population genetic models can be computationally expensive, we show how our framework leverages relatively economical graphics cards installed in modern desktops. We illustrate the versatility and general applicability of our approach for two very different case studies: antagonistic coevolution in space, and the evolution of life‐history traits in response to resource dynamics in physiologically structured populations. We find that our analyses can run up to c. 200 times faster on a single commodity graphics card than on a single CPU core, comparable to the performance gains on small‐to‐medium sized computer clusters.

Our approach therefore substantively reduces implementation difficulties to integrating ecological and evolutionary theory.
Attenuation of the anti‐contractile effect of cooling in the rat aorta by perivascular adipose tissue
Authors: Rafique Y. , AlBader M. , Oriowo M. 
Published: September 2017

Summary

In addition to providing mechanical support for blood vessels, the perivascular adipose tissue (PVAT) secretes a number of vasoactive substances and exerts an anticontractile effect. The main objective of this study was to find out whether the anticontractile effect of cooling in the rat aorta is affected by PVAT. Our hypothesis was that PVAT would enhance the anticontractile effect of cooling in the rat aorta.

Aorta segments, with or without PVAT, were used in this investigation. Cumulative concentration‐response curves were established for phenylephrine at 37°C or 24°C. Phenylephrine (10‐9M – 10‐5M) induced concentration‐dependent contractions of aorta segments with or without PVAT at 37°C. The maximum response, but not pD2 value, was reduced in aorta segments with PVAT.

Cooling the tissues to 24 °C resulted in a significant reduction in the maximum response in aorta segments without PVAT with no change in pD2 values. However, the anticontractile effect of cooling was attenuated in the presence of PVAT with no significant (p > 0.05) change in either the maximum response or pD2 value.

L‐NAME potentiated PE‐induced contractions and this was greater in aorta segments without PVAT at both temperatures.

The expression of eNOS protein and basal tissue level of nitric oxide (NO) were greater in aorta segments with PVAT at both temperatures. However, PE significantly increased tissue levels of NO only in aorta segments without PVAT.

We concluded that PVAT‐induced loss of anticontractile effect of cooling against PE‐induced contractions could be due to impaired generation of NO in aorta segments with PVAT.

Published: September 2017

AbstractThe aim of this study was to investigate the effect of human blood exposure on the compressive strength of various calcium silicate‐based cements. Two hundred and eighty‐eight customised cylindrical moulds were randomly divided into three groups according to material used: ProRoot MTA, Biodentine or CEM cement (n = 96). Each group was divided into two subgroups according to exposure conditions: PBS or blood. Then, the compressive strength of the specimens was measured after 6 h, 24 h, 72 h and 7 days. The compressive strength of CEM cement could not be measured after 6 and 24‏ h regardless of the exposure conditions nor could the compressive strength of 6 h blood‐exposed ProRoot MTA. The compressive strength of blood‐exposed ProRoot MTA was only significantly lower after 6 h, but no difference was seen at other time intervals. Blood exposed did adversely affected the compressive strength of Biodentine. The compressive strength of all groups significantly increased over time (P < 0.005).

Published: September 2017

AbstractEvent‐related potentials (ERPs) are commonly used in Neuroscience research, particularly the P3 waveform because it is associated with cognitive brain functions and is easily elicited by auditory or sensory inputs. ERPs are affected by drugs such as lorazepam, which increase the latency and decrease the amplitude of the P3 wave. In this study, auditory‐evoked ERPs were generated in 13 older healthy volunteers using an oddball tone paradigm, after administration of single 0.5 and 2 mg doses of lorazepam. Population pharmacokinetics (PK)/pharmacodynamics (PD) models were developed using nonlinear mixed‐effects methods in order to assess the effect of lorazepam on the latency and amplitude of the P3 waveforms. The PK/PD models showed that doses of 0.3 mg of lorazepam achieved approximately half of the maximum effect on the latency of the P3 waveform. For P3 amplitude, half the maximum effect was achieved with a dose of 1.2 mg of lorazepam. The PK/PD models also predicted an efficacious dose range of lorazepam, which was close to the recommended therapeutic range. The use of longitudinal P3 latency data allowed better predictions of the lorazepam efficacious dose range than P3 amplitude or aggregate exposure–response data, suggesting that latency could be a more sensitive parameter for drugs with similar mechanisms of action as lorazepam and that time course rather than single time‐point ERP data should be collected. Overall, the results suggest that P3 ERP waveforms could be used as potential non‐specific biomarkers for functional target engagement for drugs with brain activity, and PK/PD models can aid trial design and choice of doses for development of new drugs with ERP activity.
Stakeholder theory: A deliberative perspective
Authors: Richter Ulf Henning , Dow Kevin E. 
Published: September 2017

AbstractOrganizations routinely make choices when addressing conflicting stakes of their stakeholders. As stakeholder theory continues to mature, scholars continue to seek ways to make it more usable (and relevant), yet proponents continue to debate its legitimacy. Various scholarly attempts to ground stakeholder theory (empirically, instrumentally, or normatively) have not narrowed down this debate. We draw from the work of Juergen Habermas to theoretically advance stakeholder theory, and to provide practical examples to illustrate our approach. Specifically, we apply Habermas’ language‐pragmatic approach (which places strong emphasis on dialogue, participation, and procedural justice) to extend stakeholder theory by advancing seven sets of normative axioms (10 axioms in total). We conclude that a deliberative approach, with its focus on the conditions of legitimation and deliberative democracy, has the potential to become a cornerstone of stakeholder theory. The need for global stakeholder discourse and its internalization in corporate structures and institutions is exemplified by a multitude of CSR and stakeholder initiatives that have mushroomed in response to global risk scenarios such as climate change, nuclear warfare, or terrorism. Further research may help to build a functioning global governance system in order to provide guidance for management in the 21st century.
