Published: November 2014

AbstractThe relationship between microstructure and magnetic properties of a (Fe,Co)NbB-based nanocrystalline soft magnetic alloy was investigated by analytical transmission electron microscopy (TEM). The microstructures of (Fe0.5Co0.5)80Nb4B13Ge2Cu1 nanocrystalline alloys annealed at different temperatures were characterized by TEM and electron diffraction. The magnetic structures were analyzed by Lorentz microscopy and off-axis electron holography, including quantitative measurement of domain wall width, induction, and in situ magnetic domain imaging. The results indicate that the magnetic domain structure and particularly the dynamical magnetization behavior of the alloys strongly depend on the microstructure of the nanocrystalline alloys. Smaller grain size and random orientation of the fine particles decrease the magneto-crystalline anisotropy and suggests better soft magnetic properties which may be explained by the anisotropy model of Herzer.

AbstractExpose is a multi-user instrument for astrobiological and astrochemical experiments in space. Installed at the outer surface of the International Space Station, it enables investigators to study the impact of the open space environment on biological and biochemical test samples. Two Expose missions have been completed so far, designated as Expose-E (Rabbow et al. 2012) and Expose-R (Rabbow et al. this issue). One of the space-unique environmental factors offered by Expose is full-spectrum, ultraviolet (UV)-rich electromagnetic radiation from the Sun. This paper describes and analyses how on Expose-R, access of the test samples to Solar radiation degraded during space exposure in an unpredicted way. Several windows in front of the Sun-exposed test samples acquired a brown shade, resulting in a reduced transparency in visible light, UV and vacuum UV (VUV). Post-flight investigations revealed the discolouration to be caused by a homogenous film of cross-linked organic polymers at the inside of the windows. The chemical signature varied per sample carrier. No such films were found on windows from sealed, pressurized compartments, or on windows that had been kept out of the Sun. This suggests that volatile compounds originating from the interior of the Expose facility were cross-linked and photo-fixed by Solar irradiation at the rear side of the windows. The origin of the volatiles was not fully identified; most probably there was a variety of sources involved including the biological test samples, adhesives, plastics and printed circuit boards. The outer surface of the windows (pointing into space) was chemically impacted as well, with a probable effect on the transparency in VUV. The reported analysis of the window contamination on Expose-R is expected to help the interpretation of the scientific results and offers possibilities to mitigate this problem on future missions – in particular Expose-R2, the direct successor of Expose-R.
A Derivation of the Polytomous Rasch Model Based on the Most Probable Distribution Method
Authors: Noventa Stefano , Stefanutti Luca , Vidotto Giulio 
Published: November 2014

AbstractBoltzmann’s most probable distribution method is applied to derive the Polytomous Rasch model as the distribution accounting for the maximum number of possible outcomes in a test while introducing latent traits, item characteristics, and thresholds as constraints to the system. Affinities and similarities of the present result with other derivations of the model are discussed in light of the conceptual frameworks of statistical physics and of the principle of maximum entropy.

AbstractPrimary cilia contain specific receptors and channel proteins that sense the extracellular milieu. Defective ciliary function causes ciliopathies such as autosomal dominant polycystic kidney disease (ADPKD). However, little is known about how large ciliary transmembrane proteins traffic to the cilia. Polycystin-1 (PC1) and -2 (PC2), the two ADPKD gene products, are large transmembrane proteins that co-localize to cilia where they act to control proper tubular diameter. Here we describe that PC1 and PC2 must interact and form a complex to reach the trans-Golgi network (TGN) for subsequent ciliary targeting. PC1 must also be proteolytically cleaved at a GPS site for this to occur. Using yeast two-hybrid screening coupled with a candidate approach, we identify a Rabep1/GGA1/Arl3-dependent ciliary targeting mechanism, whereby Rabep1 couples the polycystin complex to a GGA1/Arl3-based ciliary trafficking module at the TGN. This study provides novel insights into the ciliary trafficking mechanism of membrane proteins.

Published: November 2014

AbstractResistance of Fusarium graminearum to carbendazim is caused by point mutations in the β2-tubulin gene. The point mutation at codon 167 (TTT → TAT, F167Y) occurs in more than 90% of field resistant isolates in China. To establish a suitable method for rapid detection of the F167Y mutation in F. graminearum, an efficient and simple method with high specificity was developed based on loop-mediated isothermal amplification (LAMP). A set of four primers was designed and optimized to specially distinguish the F167Y mutation genotype. The LAMP reaction was optimal at 63°C for 60 min. When hydroxynaphthol blue dye (HNB) was added prior to amplification, samples with DNA of the F167Y mutation developed a characteristic sky blue color after the reaction but those without DNA or with different DNA did not. Results of HNB staining method were reconfirmed by gel electrophoresis. The developed LAMP had good specificity, stability and repeatability and was suitable for monitoring carbendazim-resistance populations of F. graminearum in agricultural production.
Leptin induced GRP78 expression through the PI3K-mTOR pathway in neuronal cells

Published: November 2014

AbstractLeptin is a circulating hormone that plays a critical role in regulating energy expenditure and food intake. Evidence to suggest the involvement of endoplasmic reticulum (ER) stress in the development of obesity is increasing. To adapt against ER stress, cells trigger the unfolded protein response (UPR). The 78 kDa glucose-regulated protein (GRP78) is an ER chaperone that protects cells against ER stress by inducing protein folding. In the present study, we hypothesized that leptin may activate UPR and protect against ER stress associated with obesity. SH-SY5Y, a human neuroblastoma cell line stably transfected with the Ob-Rb leptin receptor (SH-SY5Y-ObRb), was treated with leptin. We demonstrated that leptin induced GRP78 expression. We then validated the mechanism responsible for the leptin-induced expression of GRP78. Interestingly, leptin-induced GRP78 expression was not dependent on IRE1-XBP1 pathway. On the other hand, the PI3K inhibitor, LY294002 and mTOR inhibitor, rapamycin, inhibited the leptin-induced expression of GRP78. These results suggested that the leptin-induced expression of GRP78 may be dependent on the PI3K-mTOR pathway. Leptin specifically induced GRP78 because the induction of the ER-apoptotic marker, CHOP, was not detected in leptin-treated cells. Therefore, leptin may upregulate the expression of GRP78, thereby protecting against ER stress associated with obesity.

AbstractVariations in larval fish growth rates are largely the result of variability in biotic and abiotic characteristics of the feeding environment experienced by each individual. An assessment of an individual's overall feeding success (i.e. accumulation of utilizable organic matter) can best be achieved at the time of capture when the relationships among environment, short-term feeding success as defined by gut content and long-term feeding success as defined by accumulated growth can be contrasted. Here, we investigated the relationships between average growth, feeding success, and variability in individual growth and feeding rates across a range of taxa based on a synthesis of studies in which stomach content and otolith growth were measured in the same individuals. Instantaneous measures of feeding success were highly variable and demonstrated a positive yet somewhat limited association with growth rates across all taxa. The strength of the feeding-growth relationships among taxa, and cohorts within taxa, was reflected in the autocorrelation of individual growth rates, suggesting that stable growth was achieved through consistent feeding success. However, when viewed at the individual level, faster growth was achieved in individuals with more variable growth rates, and by inference more variable past feeding success. The dichotomy in these underlying relationships may point to the importance of stochastic events in the development of exceptional individuals in a population, and may be linked to how surplus energy is allocated to individual growth rates. The positive correlation found between feeding success and growth in all taxa is consistent with the growth-survival paradigm for the larval stage of fish. However, both the correlation between feeding success and growth and the serial correlation of growth time-series was greatest in fast-growing species, suggesting that the potential for an early “critical period” regulating survival varies among species, reaching a maximum in fast-growing fish.
Factors determining the most efficient spray distribution for marine cloud brightening

Published: November 2014

We investigate the sensitivity of marine cloud brightening to the properties of the added salt particle distribution using a cloud parcel model, with an aim to address the question of, ‘what is the most efficient particle size distribution that will produce a desired cooling effect?’ We examine the effect that altering the aerosol particle size distribution has on the activation and growth of drops, i.e. the Twomey effect alone, and do not consider macrophysical cloud responses that may enhance or mitigate the Twomey effect. For all four spray generation methods considered,
Rayleigh jet
;
Taylor cone jet
;
supercritical fluid
; and
effervescent spray
, salt particles within the median dry diameter range
D
m
=30–100 nm are the most effective range of sizes. The
Rayleigh jet
method is also the most energy efficient overall. We also find that care needs to be taken when using droplet activation parametrizations: for the concentrations considered, Aitken particles do not result in a decrease in the total albedo, as was found in a recent study, and such findings are likely to be a result of the parametrizations' inability to simulate the effect of swollen aerosol particles. Our findings suggest that interstitial aerosol particles play a role in controlling the albedo rather than just the activated cloud drops, which is an effect that the parametrization methods do not consider.
Gene discovery and functional assessment of rare copy-number variants in neurodevelopmental disorders
Authors: Iyer Janani , Girirajan Santhosh 
Published: November 2014

ABSTRACTRare copy-number variants (CNVs) are a significant cause of neurodevelopmental disorders. The sequence architecture of the human genome predisposes certain individuals to deletions and duplications within specific genomic regions. While assessment of individuals with different breakpoints has identified causal genes for certain rare CNVs, deriving gene-phenotype correlations for rare CNVs with similar breakpoints has been challenging. We present a comprehensive review of the literature related to genetic architecture that is predisposed to recurrent rearrangements, and functional evaluation of deletions, duplications, and candidate genes within rare CNV intervals using mouse, zebrafish, and fruit fly models. It is clear that phenotypic assessment and complete genetic evaluation of large cohorts of individuals carrying specific CNVs and functional evaluation using multiple animal models are necessary to understand the molecular genetic basis of neurodevelopmental disorders.
Political behavior, trustworthiness, job satisfaction, and commitment
Authors: Olson Bradley , Bao Yongjian , Parayitam Satyanarayana 
Published: November 2014

Purpose– The purpose of this paper is to examine the effects trustworthiness can have on the perception of organizational politics and organizational outcomes. Most studies on organizational politics examine the negative effects of organizational politics on organizational outcomes such as organizational commitment. This study focuses on moderators that can decrease these negative effects.Design/methodology/approach– The organization landscape consists of Chinese organizations, with a total of 249 employees who were surveyed in 2009. Multiple and moderated hierarchical regression were used in the analyses.Findings– The results show that trustworthiness moderates the negative effects of organizational politics on job satisfaction, affective commitment and normative commitment. These findings support the importance of combating the negative effects that are in most, if not all, organizations.Originality/value– This study uses as its sample an Asian culture that has been under-represented in organizational politics studies, as the majority of these studies are conducted in North America. Yet, organizational politics likely occurs in organizations worldwide.
Ownership governance, institutional pressures and circular economy accounting information disclosure
Authors: Wang PuCha , Che Fei , Fan ShanShan , Gu Chen 
Published: November 2014

Purpose
– This paper aims to explore the determinants of circular economy accounting information disclosure quality, and also to make empirical analysis on the relationship between circular economy accounting information disclosure quality and corporate ownership governance and institutional pressures according to institutional theory and corporate governance theory. Finally, this paper provides some corresponding suggestions for heightening circular economy accounting information disclosure quality.

Design/methodology/approach
– This paper constructs enterprise circular economy accounting information disclosure model with Chinese characteristics. First, it takes disclosure index method to measure enterprise circular economy accounting information disclosure quality, followed by the hypotheses of this study. Then, this study employs a statistical analysis technique to empirically study the relationship between enterprise circular economy accounting information disclosure quality and ownership governance and institutional pressures, to study the ways to heighten enterprise circular economy accounting information disclosure quality in Chinese background.

Findings
– Ownership governance and institutional pressures mainly determine quality of circular economy accounting information disclosure. This paper draws the following conclusions: Chinese listed companies have heightened their circular economy accounting information disclosure quality due to ownership concentration, shareholding of institutional investors, mandatory disclosure, capital structure and assets size. However, the circular economy accounting information disclosure quality has low correlation with the profitability and the location of listed companies.

Originality/value
– Both in China and the West, few scholars or experts adopt empirical research to study the determinants of circular economy accounting information disclosure quality in an institutional theory and corporate governance theory perspective based on China’s supervisory system background. This paper makes a thorough analysis of the factors that affect listed companies’ circular economy accounting information disclosure quality, and provides some corresponding suggestions relevant for heightening circular economy accounting information disclosure quality.
Store managers – the seismographs in shopping centres
Authors: Teller Christoph , Alexander Andrew 
Published: November 2014

Purpose– The aim of this paper is to investigate the link between store managers’ evaluation of how customers assess a shopping centre and their own evaluation of the centre and, based on that, the relevance of store managers in reflecting on and informing the management and marketing practices of the local shopping centre management.Design/methodology/approach– A conceptual model is developed based on the network and boundary-spanning theories. The model is tested using a Web-based survey of 217 managers, representing stores located in shopping malls, and by applying covariance-based structural equation modelling.Findings– The study reveals store managers to be engaging in a significant information-processing pathway, from customers’ evaluation of the shopping centre (as perceived by the store manager) to their own evaluation of the centre in terms of managerial satisfaction and loyalty.Research limitations/implications– The empirical study focuses exclusively on shopping malls and thus does not consider other shopping centre forms such as town centres and retail parks.Practical implications– This paper concludes that store managers have the potential to be informational boundary spanners and, thus, valuable resources to inform and give feedback to shopping centre management.Originality/value– The contribution of this paper is to provide a more complete understanding of the role of the store manager as an integral actor in the shopping centre in terms of informational boundary spanning between the retail organisation, the customers and local shopping centre management.
Publicity and advertising: what matter most for sales?
Authors: E. Spotts Harlan , G. Weinberger Marc , F. Weinberger Michelle 
Published: November 2014

Purpose– The purpose of this research is to understand the relationship between publicity, advertising activity and corporate sales in the context of a company’s existing reputation.Design/methodology/approach– The study brings together four unique industry datasets and uses discriminant analysis and multiple regression methods to examine the relationship between existing corporate reputation, publicity, advertising activity and sales levels for major multi-national companies in the technology products sector.Findings– Positive publicity is most important in distinguishing between firms with higher and lower sales. The effects of negative publicity and advertising are dependent on a firm’s existing reputation. For companies with weaker reputations, positive publicity in tandem with business-to-consumer (B2C) advertising is most highly associated with higher company sales. Conversely, for firms with stronger existing reputations, advertising has a significantly diminished role; positive and even negative publicity are most crucial in distinguishing between companies with high and low sales. Negative publicity can be harmful to these firms though if it is not balanced by more positive publicity. Finally, the topic of news coverage is related to sales. Generally, stories that are positive reporting on business outcomes, leadership and business future and marketing practices are most important in discriminating between firms with stronger vs weaker sales.Practical implications– For this set of technology product firms, publicity and advertising are relevant for sales. Firms with higher levels of sales have both more positive and negative publicity, but the volume of positive stories is much higher. Attracting negative publicity is common for firms that achieve higher sales, but it is offset by a greater number of positive stories, an aspect that public relations efforts can influence. B2C advertising spending meanwhile matters more for firms with weaker rather than stronger existing corporate reputations. It is most effective for firms with weaker existing reputations to maximize the positive signals in the marketplace as exemplified by positive publicity and B2C advertising efforts.Originality/value– Little research has examined the relationship between different forms of corporate communications and sales; this study is a rare examination using publicity, advertising spending, existing reputation and sales in a durable goods and services context where there has been a particular dearth of even basic advertising studies. Beyond understanding the relative importance of publicity v. advertising, it also uniquely focuses on the individual topics of news publicity.
