Authors: Sobkowiak Robert , Kaczmarek Piotr , Kowalski Mateusz , Kabaciński Rafał , Lesicki Andrzej 
Published: January 2017

AbstractNicotine decreases food intake, and smokers often report that they smoke to control their weight. To see whether similar phenomena could be observed in the model organismCaenorhabditis elegans, we challenged drug-naϊve nematodes with a chronic low (0.01 mM) and high (1 mM) nicotine concentration for 55 h (from hatching to adulthood). After that, we recorded changes in their behavior in a nicotine gradient, where they could choose a desired nicotine concentration. By using a combination of behavioral and morphometric methods, we found that both nicotine and food modulate worm behavior. In the presence of food the nematodes adapted to the low nicotine concentration, when placed in the gradient, chose a similar nicotine concentration likeC. elegansadapted to the high nicotine concentration. However, in the absence of food, the nematodes adapted to the low nicotine concentration, when placed in the gradient of this alkaloid, chose a similar nicotine concentration like naive worms. The nematodes growing up in the presence of high concentrations of nicotine had a statistically smaller body size, compared to the control condition, and the presence of food did not cause any enhanced slowing movement. These results provide a platform for more detailed molecular and cellular studies of nicotine addiction and food intake in this model organism.
Precision navigation system design for Moon penetrator
Authors: Wang Xiaogang , Qin Wutao , Bai Yuliang , Cui Naigang 
Published: January 2017

Purpose
Penetrator plays an important role in the exploration of Moon and Mars. The navigation method is a key technology during the development of penetrator. To meet the high accuracy requirements of Moon penetrator, this paper aims to propose two kinds of navigation systems.

Design/methodology/approach
The line of sight of vision sensor between the penetrator and Moon orbiter could be utilized as the measurement during the navigation system design. However, the analysis of observability shows that the navigation system cannot estimate the position and velocity of penetrator, when the line of sight measurement is the only resource of information. Therefore, the Doppler measurement due to the relative motion between penetrator and the orbiter is used as the supplement. The other option is the relative range measurement between penetrator and the orbiter. The sigma-point Kalman Filtering is implemented to fuse the information from the vision sensor and Doppler or rangefinder. The observability of two navigation system is analyzed.

Findings
The sigma-point Kalman filtering could be used based on vision sensor and Doppler radar or laser rangefinder to give an accurate estimation of Moon penetrator position and velocity without increasing the payload of Moon penetrator or decreasing the estimation accuracy. However, the simulation result shows that the last method is better. The observability analysis also proves this conclusion.

Practical implications
Two navigation systems are proposed, and the simulations show that both systems can provide accurate estimation of states of penetrator.

Originality/value
Two navigation methods are proposed, and the observability of these navigation systems is analyzed. The sigma-point Kalman filtering is first introduced to the vision-based navigation system for Moon penetrator to provide precision navigation during the descent phase of Moon penetrator.

Published: January 2017

Purpose
The purpose of this paper is to study extensive enlargement and safety of flight data recorder memory.

Design/methodology/approach
The study involves the moving the memory of flight data recorders from an internal embedded device to a cloud.

Findings
The implementation has made the embedded memory device of flight data recorder effectively unlimited, and, hence, much more information can be stored.

Research limitations/implications
The possibility of a flight data recorder to be damaged or lost in a crash is not so high, but the implementation can be very helpful in cases such as aerial disappearances.

Practical implications
The implication is larger and protected memory for flight data recorders.

Social implications
Finding reasons for crashes is faster, and immediate actions can be taken to find remedy to the failures.

Originality/value
The use of internet and cellphones in airplanes is nothing special at present. It is suggested to take this technology for flight data recorders as well.
Risk aversion in crop insurance program purchase decisions
Authors: Lyu Kaiyu , Barré Thomas J. 
Published: January 2017

PurposeThe purpose of this paper is to contribute to the aforementioned literature on the linkage between economic activity and human preference by estimating the cross-sectional determinants of farmers’ participation in participation in crop insurance programs (CIPs) and identifying the impediments preventing the remaining farmers from participating.Design/methodology/approachUsing the unique data sets of risk preference experiments and maize producer surveys pertaining to the maize production areas of China, this paper explores the determinants of farmers’ CIPs and scrutinizes the role of risk aversion in farmers’ CIP purchase decisions under the expected utility maximization framework. And a “non-zero threshold probit model” is used for the analysis.FindingsThe results show that risk aversion plays an important role in CIP purchase decision-making, not only in the form of its direct effect but also with regard to the interaction term and expected loss. Furthermore, if the insured amount is high enough, then risk aversion will no longer affect insurance purchase. Additionally, purchase experience, CIP environment (village purchase ratio), and contract items (insured amounts) are significant determinates in these decisions. There is no significant evidence to suggest that serious adverse selection exists in the sampling areas.Originality/valueOne theoretical model is established which considered not only general variables like farmers’ production and household information, but also conditions and terms in the insurance policies. The unique experimental method is used to measure farmers’ risk aversion. Both the role of risk aversion and its’ interaction terms with others in CIP participation are scrutinized to identify complicated influences under the context of real society.
The impact of Wal-Mart Supercenters’ entry on incumbent supermarkets’ profit margins
Authors: Di Yuan , Lopez Rigoberto , Liu Xiaoou 
Published: January 2017

Purpose
The purpose of this paper is to quantify the impact of Wal-Mart Supercenters (WMSs) on supermarkets’ profit margins using fluid milk in the Dallas/Fort Worth metropolitan area in the USA as a case study.

Design/methodology/approach
The authors develop a two-stage dynamic entry game to model market competition in the pre- and post-WMS stages, and test the theoretical model using the method of simulated moments and milk scanner data from Dallas/Fort Worth supermarkets.

Findings
The empirical findings show that the entry of WMSs accounts for an average of about 16.29-25.69 percent decline in milk profit margins of nearby, or incumbent, supermarkets. Economies of scale and chain synergies are found to be five times more significant for WMSs than for incumbent supermarkets, granting Wal-Mart a significant competitive edge.

Originality/value
This paper quantifies the impact of WMS’s entry on incumbent supermarkets’ profit margins through a structural model of entry. In addition, this paper assesses the effect economies of scale stemming from the ability to provide shopping convenience to consumers as well as chain economies from operating stores near each other.
Meta-analyses of culture’s consequences for acquisition performance
Authors: Rottig Daniel 
Published: January 2017

PurposeThe purpose of this paper is to provide a quantitative integration of the existing empirical body of literature on culture and acquisition performance.Design/methodology/approachThe study is based on a meta-analytical approach that synthesizes 189 effect sizes from 24 independent samples with a total sample size ofn=5,496 acquisitions.FindingsThis meta-analytical study found a consistently negative and significant relationship between organizational cultural differences and acquisition performance, and a dual effect of national cultural differences (i.e. cultural distance) on acquisition performance. It further identified significant methodological and contextual moderators and discusses the implications for acquisitions in emerging markets.Research limitations/implicationsDue to the nature of meta-analyses, this study is based on existing (i.e. available secondary) data. Future research may collect novel, primary data to further test the conceptual model and respective relationships developed therein.Practical implicationsThis study sheds light onto the culture-based performance determinants of acquisitions and the effects of methodological and contextual moderator variables. Given the significant importance of acquisitions across organizational and national cultures, the findings may inform business practitioners when developing sustainable strategies to successfully integrate organizations that are culturally different and/or are located in culturally diverse environments.Social implicationsA better understanding about the culture-based performance determinants of acquisitions may inform public policy makers about how to regulate and set incentives for acquisitions, which constitute a main vehicle through which firms undertake foreign direct investment, and which can be considered a global sustainable growth strategy for multinational corporations and entire economies.Originality/valueThis paper is original in that it provides a large-scale and in-depth quantitative integration and synthesis of the empirical literature on culture and acquisition performance based on a meta-analytical approach and so has important theoretical value and empirical implications for future emerging market research.
Extending the supply chain visibility boundary
Authors: Busse Christian , Schleper Martin C. , Weilenmann Jenny , Wagner Stephan M. 
Published: January 2017

Purpose
The purpose of this paper is to investigate how buying firms facing low supply chain visibility can utilize their stakeholder network to identify salient supply chain sustainability risks (SCSR).

Design/methodology/approach
The study employs a design science approach to develop a procedural model for identifying SCSR as a new artifact. A small-scale field-testing study in a food supply chain of a Swiss retail firm demonstrates its applicability and pragmatic validity.

Findings
When stakeholder knowledge external to the supply chain is regarded as a valuable resource, a generic understanding of a buying firm’s supply chain suffices to identify SCSR hotspots without creating complexity for the SCSR management.

Research limitations/implications
The paper contributes to the study of SCSR by identifying mechanisms buying firms can employ to identify SCSR hotspots and fostering the nascent understanding of responsibility attribution by stakeholders. Moreover, the emerging theory of the supply chain is enriched by paving a way to extend the supply chain visibility boundary. The procedural model is presumably most useful in contexts of elevated stakeholder pressure and low supply chain visibility. Future research should seek to validate and improve the effectiveness of the newly designed artifact.

Practical implications
The procedural model is directly applicable in corporate practice to the identification of SCSR. Moreover, its application fosters the understanding of a firm’s supply chain and its stakeholder network.

Originality/value
SCSR is an increasingly important phenomenon in corporate practice that has received only scarce research attention. The design science approach represents a valuable means for generating theoretical insights and emergent solutions to the real-world problem of SCSR identification.

Published: January 2017

Purpose
The purpose of this paper is to develop a comprehensive research model that can explain potential customers’ behavioral intentions to adopt and use smart home services.

Design/methodology/approach
This study proposes and validates a new theoretical model that extends the theory of planned behavior. Partial least squares analysis is employed to test the research model and corresponding hypotheses on data collected from 216 survey samples.

Findings
Mobility, security/privacy risk, and trust in the service provider are important factors affecting the adoption of smart home services.

Practical implications
To increase potential users’ adoption rate, service providers should focus on developing mobility-related services that enable people to access smart home services while on the move using mobile devices via control and monitoring functions.

Originality/value
This study is the first empirical attempt to examine user acceptance of smart home services, as most of the prior literature has concerned technical features.
Why not be “smarter”? Examining the factors that influence the behavioral intentions of non-smartphone users
Authors: Lin Chen-Yu , Chao Yu-Chuang , Tang Tzy-Wen 
Published: January 2017

Purpose
Despite the evident and dramatic increase in smartphone usage worldwide, some consumers continue to use traditional mobile phones. The purpose of this paper is to investigate the behavioral intentions of these laggard and non-smartphone users.

Design/methodology/approach
This current study examines the effects of consumer demographics, psychographics, and smartphone characteristics on the intentions of non-smartphone consumers to switch or resist the use of smartphones. Data were collected using a convenience sample of non-smartphone users in Taiwan. The proposed model is tested using the consistent partial least squares (PLSc) path modeling technique.

Findings
PLSc results indicate that consumer psychographics and smartphone characteristics play more important roles than consumer demographics. Specifically, price consciousness, nostalgia, and perceived ease of use are good predictors of intention to switch, whereas perceived usefulness and ease of use are strong predictors of the intention to resist smartphone adoption.

Practical implications
The results of this study have implications for mobile phone vendors and mobile manufacturers who target non-smartphone users or laggard adopters.

Originality/value
This study is among the few that focus on non-smartphone users’ perceptions of smartphones. Hence, this empirical study could contribute to the development and testing of theories related to the smartphone adoption process.

Authors: Martin Judith , Hofmann Erik 
Published: January 2017

Purpose
The purpose of this paper is the analysis of reasons to involve financial service providers (FSPs) in the integrated management of supply chain flows through supply chain finance (SCF) practices. In addition, service requirements are derived for FSPs in order to respond to company needs related to SCF practices.

Design/methodology/approach
The selected methodology represents a multi-method approach. First, a survey with 62 companies from Switzerland and ten expert interviews were applied to analyze company needs. Second, the study was complemented with a review of gray press, online offers and 11 expert interviews on the service offer of FSPs for managing supply chain flows.

Findings
The results derive company needs for an integrated management of supply chain flows. The company needs are matched with available service offer of FSPs. Based on this match quality gaps are identified and service requirements are derived. The results describe initial measures to close the quality gaps.

Research limitations/implications
This research primarily focuses on financial flows related to the working capital of companies thereby neglecting fixed assets.

Practical implications
The results provide companies with a structured process to analyze the value added of FSPs. FSPs can use the results to better match their service offer with company needs.

Originality/value
This research contributes to research on SCF by developing a structured process for analyzing the company needs for SCF practices as well as the value added of FSPs in offering these practices.
Sulfonation and Antioxidative Evaluation of Polysaccharides from Pleurotus Mushroom and Streptococcus thermophilus Bacteria: A Review
Authors: Li Siqian , Dai Shuhong , Shah Nagendra Prasad 
Published: January 2017

AbstractHuman beings are equipped with antioxidant defense systems to neutralize free radicals as free radicals could damage macromolecules, subsequently resulting in serious diseases. Researchers have been attracted to search for potential natural antioxidants to reduce oxidative damage. Pleurotus and Streptococcus thermophilus have been chosen as sources of sustainable bioactive compounds that have been consumed for thousands of years. Polysaccharides are important bioactive components produced by Pleurotus mushrooms and Streptococcus thermophilus bacteria. Additionally, there is a continued interest in sulfonation of crude polysaccharides from both sources, since sulfonation has been found to improve or create new bioactive properties in polysaccharides. Both crude and sulfated polysaccharides with good antioxidant capacities have great potential for the further development as commercial products. This review focuses on characterization, sulfonation methods, and antioxidant capacity evaluations of polysaccharides from Pleurotus and S. thermophilus. Common antioxidant capacity assays, including the mechanisms underlying each assay, and various experimental procedures are also discussed.
