Published: May 2017

SummaryThe e‐commerce has got great development in the past decades and brings great convenience to people. Users can obtain all kinds of services through e‐commerce platform with mobile device from anywhere and at anytime. To make it work well, e‐commerce platform must be secure and provide privacy preserving. To achieve this goal, Islam et al. proposed a dynamic identity‐based remote user mutual authentication scheme with smart card using Elliptic Curve Cryptography(ECC). Islam et al claimed that the security of their scheme was good enough to resist various attacks. However, we demonstrate that their scheme is vulnerable to insider attack and suffers from off‐line password guessing attack if smart card is compromised. To overcome the deficiencies, we present an improved scheme over Islam's scheme. The security proof and analysis shows that our scheme can also provide user anonymity and mutual authentication, and the security is enough to against relay attack, impersonation attack, and other common secure attackers. The performance analysis shows that the proposed scheme is more efficient than Islam et al's scheme.
Identifying target reference points for harvesting assessment‐limited wildlife populations: a case study
Authors: Stevens Bryan S. , Bence James R. , Porter William F. , Jones Michael L. 
Published: May 2017

AbstractIdentifying appropriate strategies for sustainable harvest is a challenge for many terrestrial vertebrate species because of uncertain system dynamics, limited data to inform population models, and potentially conflicting objectives that seek to harvest and maintain populations at desirable levels. The absence of monitoring and assessment infrastructure needed to regularly estimate abundance accentuates this challenge for many species, and limits application of rigorous state‐dependent frameworks for decision making that are commonly advocated in natural resource management. Reference points, which define management targets or triggers for changing management, are often used to guide decision‐making, but suffer from ambiguity when developed without explicit consideration of uncertainty or trade‐offs among competing objectives. We describe an approach for developing unambiguous target reference points for assessment‐limited species using structured decision making, and demonstrate the approach to develop target harvest rates for management of fall Wild Turkey (Meleagris gallopavo) harvests in the face of uncertain population and harvest dynamics. We use simulation and decision analyses to identify harvest rates that are optimal for accomplishing explicit management objectives in the face of uncertainty, and harvest rates with robust performance over broad regions of the demographic and harvest model parameter space. We demonstrate that population and harvest parameters commonly uncertain to wildlife managers interact to determine appropriate target harvest rates for Wild Turkeys, and that formally acknowledging a range of plausible values for structurally uncertain parameters results in more conservative target reference points than suggested by previously published studies. The structured decision making framework described here provides a natural conceptual and quantitative framework for extending our approach to develop unambiguous harvest targets for other assessment‐limited wildlife populations while formally acknowledging structural uncertainty in system dynamics.

Published: May 2017

AbstractThe ecological impacts of biological invasion are generalized with difficulty since these impacts are commonly species‐ or ecosystem‐specific. A noxious invasive plant, Chromolaena odorata, has invaded broad regions, but limited attention has been paid to clarify the ecological impacts of this invasive plant on soil carbon (C) and nitrogen (N) storage in invaded ecosystems. This study was conducted to investigate changes in the labile and total soil C and N fractions in the surface and subsurface soil layers in non‐invaded plots, plots with slight (30%) or severe (100%) invasion, and a restored forest plot with native tree and shrub species within a tropical savanna. Our results showed that different severities of C. odorata invasion induced inconsistent responses of the soil C and N fractions in the investigated tropical savanna. In particular, slight invasion did not alter or decreased the total and labile soil C and N fractions, and severe invasion significantly increased most of the total and labile soil C and N fractions. The encroachment of woody species significantly increased the soil C and N contents, with significantly higher increases than in the invaded plots. Our results suggest that the impacts of invasion on soil C and N fractions could vary depending on invasion severity. Therefore, comparisons of the invaded and non‐invaded plots with invasion duration or severity overlooked are likely to result in biased conclusions regarding the invasion‐induced ecological consequences in terrestrial ecosystems. Moreover, C. odorata invasion can alter soil nutrient conditions according to the needs of C. odorata establishment at different stages and consequently affect the soil C and N contents in this tropical ecosystem.

Effects of beta‐cyclodextrin (β‐CD), chitosan, and collagen on tocopherol and oxidative stability in heated oils were determined under moisture added condition at 180°C in this study. Collagen was added in the form of a mesh structure with different pore sizes (50, 100, 200, and 300 μm) whereas chitosan was added in the form of gel. Presence of 1% w/w β‐CD significantly (p < 0.05) reduced the formation of p‐anisidine compared to controls. Collagens also acted as antioxidants irrespective of pore sizes whereas chitosan gel failed to act as antioxidant or prooxidant. Collagen and β‐CD significantly (p < 0.05) protected the decomposition of total tocopherols while chitosan failed to show such protection. Collagen with pore size of 300 μm significantly (p < 0.05) stabilized γ‐ and δ‐ tocopherols compared to controls and oils added with β‐CD, chitosan, or collagen with pore size of 50 μm. The addition of β‐CD, chitosan, and collagen significantly (p < 0.05) reduced the moisture content in heated oil compared to controls. β‐CD or collagen mesh structure can be used in heated oils like frying condition to control the rates of lipid oxidation. Addition of biopolymers may extend the oxidative stability and shelf‐life of heated oils and help to produce more food products.Practical applications: β‐Cyclodextrin and collagen mesh structure in heated oils can enhance the stability of antioxidants like tocopherols and the oxidative stability were greatly enhanced in heated oils. Therefore, addition of β‐cylcodextrin or collagen mesh structure can be used in heated oils like frying condition to control the rates of lipid oxidation and extend the operation time in frying oils.Addition of β‐cyclodextrin and collagen mesh structure significantly enhanced the oxidative stability in heated oils. The stability of tocopherols especially γ‐ and δ‐tocopherols increases when collagen mesh structure is added. Moisture content is decreased in heated oils when β‐cyclodextrin, chitosan, and collagen are added.

Published: May 2017

AbstractThis paper examines how temporally differentiated representations of ingroup victimhood and acknowledgment of outgroup suffering relate to present intergroup attitudes. A mixed‐methods research was conducted in Bulgaria where both the ethnic majority and the Bulgarian Turkish minority can be viewed as victims and perpetrators in the past. Multigroup path models (Study 1) revealed that for the majority (N = 192) collective victimhood was positively related to social distance through reduced forgiveness and through reduced collective guilt for a different historical era. Acknowledgment of outgroup suffering, in turn, was associated with reduced social distance through heightened guilt and through forgiveness for another era. Among the Bulgarian Turks (N = 160), the result pattern differed. Collective victimhood was unrelated to forgiveness. Moreover, the relationship between guilt and social distance was positive. Semi‐directive interviews (Study 2) revealed different meanings attributed to the events by the two groups. The impact of intertwined historical representations on current‐day prejudice is discussed in light of power asymmetry between groups.
Holding your flag: The effects of exposure to a regional symbol on people's behavior
Authors: Guéguen Nicolas , Martin Angélique , Stefan Jordy 
Published: May 2017

AbstractResearch has shown that exposure to the national flag alters people's behavior and political and intergroup judgments. In several field studies conducted in an area of France with a strong regional identity, we examined the effect of the presence of the regional flag versus the national flag versus no flag on behaviors. Various situations (e.g., money solicitation, implicit helping behavior, food tasting) were tested in Brittany, on the French west Atlantic coast. Car drivers, passersby in the street, and patrons in bakeries were exposed to no flag versus the French flag versus the Brittany flag held by requesters or presented on a product or on a car. Findings showed that the regional flag increased helping behavior dramatically. Other studies also revealed that the presence of the Brittany flag reduced aggressiveness and influenced preference for food products. The power of a flag as a symbol that could increase in‐group membership is discussed.
Seeing faces: The role of brand visual processing and social connection in brand liking

Published: May 2017

AbstractThis paper investigates how brands—through visuals—can fill a void for consumers experiencing a lack of social connection. Using psychometric measures and mock advertisements with visuals of human faces and non‐faces, Study 1 shows that seeing faces relates to greater brand liking with processing fluency mediating, and individual loneliness and tendency to anthropomorphize moderating the effect. Study 2 replicates findings with other‐race faces corroborating that fluency but not ethnic self‐referencing underlies the effect. Study 3 complements the psychometric measures of Studies 1 and 2 with eye tracking data to demonstrate that fluency correlates with distinct patterns of attention. Study 4 uses actual brand stimuli to show that effects are robust and extend beyond advertisements. Taken together, the findings show that communicating brand names in conjunction with visuals seen by consumers as human faces can increase brand liking.
In‐group relevance facilitates learning across existing and new associations

Published: May 2017

AbstractStudies have shown that attention prioritizes stimuli associated with the in‐group. However, the extent to which this so‐called in‐group favoritism is driven by relevance is not clear. Here, we investigated this issue in a group of university rowers using a novel perceptual matching task based on the team label–color associations. Across three experiments, participants showed enhanced performance for the in‐group stimulus regardless of its familiarity level. These findings confirmed the role of relevance in in‐group favoritism. In a further control study, the advantage for certain stimuli was not found in an independent sample of participants who were not identified with the teams but were familiar with the label–color associations, indicating that in‐group relevance was necessary for the in‐group favoritism. Together, these findings suggest that in‐group relevance facilitates learning across existing and new associations. The consequences of these findings for understanding in‐group effects on perceptual processing are discussed.
Romantic love versus reproduction opportunities: Disentangling the contributions of different anxiety buffers under conditions of existential threat
Authors: Hoppe Annedore , Fritsche Immo , Koranyi Nicolas 
Published: May 2017

AbstractRomantic relationships and offspring are discussed as anxiety buffers in terror management processes. We examined the relationship between these possible buffers and tested whether romantic relationships reduce existential threat due to reproduction opportunities or if they represent a distinct anxiety buffer. Contrary to our initial expectations, thinking about a positive romantic relationship without (vs. with) own children increased partner affect (Study 1) and commitment (Study 2) and decreased punishment intentions (Study 2) after mortality salience. These effects were mediated by participants' desire for romantic love. Furthermore, thinking about positive nonparental (vs. parental) romantic relationships lowered death‐thought accessibility (Study 3). Together, these findings suggest that romantic relationships form a distinct anxiety buffer that is only effective when the cultural (romance) instead of the biological (having children) nature of the relationship is highlighted. We discuss the role of anxiety buffer salience for determining whether offspring concerns buffer or increase existential threat.

Published: May 2017

AbstractIntolerance of uncertainty is an empirically supported transdiagnostic construct that may have relevance in understanding eating disorders. We conducted a meta‐analysis and systematic review of intolerance of uncertainty in eating disorders using Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. We calculated random‐effects standardised mean differences (SMD) for studies utilising the Intolerance of Uncertainty Scale (IUS) and summarised additional studies descriptively. Women with eating disorders have significantly higher IUS scores compared with healthy controls (SMD = 1.90; 95% C.I. 1.24 to 2.56; p < 0.001). Post hoc meta‐analysis revealed significant differences when comparing women with anorexia nervosa with controls (SMD = 2.16; 95% C.I. 1.14 to 3.18; p < 0.001) and women with bulimia nervosa with controls (SMD = 2.03; 95% C.I. 1.30 to 2.75; p < 0.001). Our synthesis of findings suggests that intolerance of uncertainty may represent a vulnerability and maintenance factor for eating disorders and potential target of cognitive, behavioural, interoceptive and affective symptoms.

Published: May 2017

BackgroundAnxiety disorders (AD) are very prevalent in the elderly, tend to compromise quality of life, and generate substantial costs. Considering that the prevention and early detection of anxiety may be relevant to increase health gains in older adults, it would be of great interest to identify whether the joint hypermobility syndrome (JHS) is also related to anxiety disorders in this age range.MethodsCross‐sectional data was collected in a sample of 108 subjects in a rural town in Spain. Instruments included Spielberger STAI, a modified Wolpe Fear Survey Schedule, General health Questionnaire (GHQ)‐28, and the anxiety and mood disorders section of the SCID, to assess past year prevalence of anxiety disorders. JHS was evaluated by trained examiners using the “Hospital del Mar criteria”.ResultsAmong the 108 subjects (55% women, 45% men) over 60 years old, 21.3% meet criteria for JHS. These subjects scored significantly higher in both State (F = 5.53; p = 0.02) and Trait (F = 4.68; p = 0.03) anxiety and the GHQ 28 (F = 6.29; p = 0.01). Compared with non JHS subjects, they had more AD (34.8% vs. 11.8%; x2 = 6.90; p = 0.02) and mood disorders (30.4% vs. 10.6%; x2 = 5.65; p = 0.041) in the past year prevalence. A multiple logistic regression analysis showed that both JHS (β = 0.196; p = 0.04) and fears (β = 0.34; p = 0.001) are predictors of AD (r2 = 188; p = 0.001) in this population.ConclusionsJoint hypermobility syndrome is associated with anxiety in the elderly population, and it may be used as a physical marker for AD among subjects within this age range.

The research applications of new heat insulation composite material in automobiles
Authors: Bao Yue , Zhao Xiaoyu 
Published: May 2017

AbstractWith the rapid development of its unique advantages, nonwoven fabric has become the leading material of automotive textiles. Nonwoven fabric has become an ideal material for automobiles and replaced traditional textiles and plastic products. This paper takes a car as the research model. A DRL‐2B thermal conductivity tester was used to test thermal conductivity of the material based on the plate method. Material systems and structures of new types of heat insulation composite materials were determined according to test results and the theory of heat transfer. Then, the final new type of heat insulation material was determined by calculating and comparing average heat transfer coefficients and heat transfer between traditional insulation materials and new types of heat insulation materials. The calculated results were verified by experiments in this paper. All the test results show that the new type of composite insulation material is significantly better than traditional insulation materials, and the test results match the calculated results.
Plant source water apportionment using stable isotopes: A comparison of simple linear, two‐compartment mixing model approaches
Authors: Evaristo Jaivime , McDonnell Jeffrey J. , Clemens John 
Published: May 2017

AbstractPlant source water identification using stable isotopes is now a common practice in ecohydrological process investigations. Notwithstanding, little critical evaluation of the approaches for source apportionment have been conducted. Here, we present a critical evaluation of the main methods used for source apportionment between vadose and saturated zone water: simple mass balance and Bayesian mixing models. We leverage new isotope stem water samples from a diverse set of tree species in a strikingly uniform terrain and soil conditions at the Christchurch Botanic Garden, New Zealand. Our results show that using δ2H alone in a simple, two‐source mass balance approach leads to erroneous results, particularly an apparent overestimation of groundwater contribution to xylem. Alternatively, using both δ2H and δ18O in a Bayesian inference framework improves the source water estimates and is more useful than the simple mass balance approach, particularly when soil and groundwater contributions are relatively disproportionate. We suggest that plant source water quantification methods should take into consideration the possible effects of 2H/1H fractionation. The Bayesian inference approach used here may be less sensitive to 2H/1H fractionation effects than simple mass balance methods.

ABSTRACTOxidative conditions of the eye could contribute to retinal cells loss through activating the Fas‐L/Fas pathway. This phenomenon is one of the leading causes of some ocular diseases like age‐related macular degeneration (AMD). By targeting proteins at their mRNA level, microRNAs (miRNAs) can regulate gene expression and cell function. The aim of the present study is to investigate Fas targeting by miR‐374a and find whether it can inhibit Fas‐mediated apoptosis in primary human retinal pigment epithelial (RPE) cells under oxidative stress. So, the primary human RPE cells were transfected with pre‐miR‐374a pLEX construct using polymeric carrier and were exposed to H2O2 (200 μM) as an oxidant agent for induction of Fas expression. Fas expression at mRNA and protein level was evaluated by quantitative real‐time PCR and Western blot analysis, respectively. These results revealed that miR‐374a could prevent Fas upregulation under oxidative conditions. Moreover, Luciferase activity assay confirmed that Fas could be a direct target of miR‐374a. The cell viability studies demonstrated that caspase‐3 activity was negligible in miR‐374a treated cells compared to the controls. Our data suggest miR‐374a is a negative regulator of Fas death receptor which is able to enhance the cell survival and protect RPE cells against oxidative conditions. J. Cell.

Cases which were treated by giving grounds to delusion: What is client‐centered medical care?
Authors: Suda Michio , Onoe Hisakazu , Harigai Kayoko 
Published: May 2017

AbstractDelusion is a subjective belief, which is based on a mistaken judgment without any grounds. We thought the symptoms from the perspective of cognitive science. In the process of discovering the grounds by which delusions occur in patients, by the setting of goals which are not restricted by others, and by enhancing the presence such that new frame construction with integrity can be continuously possible, we report the case that delusion has disappeared and has been cured. When considering what client‐centered medical care is, it is necessary to reconsider the mechanism of cognition of patients from the perspective of information fields which occur within relationships, and to support patients so that they can select what they want to do from the standpoint of the goals they seek.
