Published: August 2017

AbstractThe Morris water task (MWT) is commonly used to assess rodent spatial learning and memory. Our goal was to develop a 3-phase variant of the hidden goal water task to assess old and new spatial memories acquired in the same context using various measures of spatial learning in C57BL/6 mice. In the first phase, mice were pre-trained to an initially hidden location. The second phase consisted of a massed training session to a new location in the same apparatus and context. The final phase consisted of a competition test between the original and new platform locations.AppNL-G-F/NL-G-Fmice, a novel transgenic mouse model for Alzheimer’s disease (AD), were also used as an independent variable to validate this 3-phase variant of MWT. The results of the present study showed that C57 mice acquired and retained both the old and new location representations; however,AppNL-G-F/NL-G-Fmice retained a recently acquired spatial memory but did not remember the old location acquired in the same apparatus and context. The results showed that C57 mice can show precise place learning and memory with the right amount of training and acquire and retain multiple spatial memory locations in the same environment whereas this ability was impaired inAppNL-G-F/NL-G-Fmice. In the visible platform test, however, all groups of mice showed normal sensorimotor ability and motivation. These findings indicate that this new version of the MWT provides a robust way for assessment of old and new memories in mice. This paradigm could also be exploited to assess manipulations of neural circuits implicated in learning and memory processes as well as for research investigating human brain diseases.

AbstractAutophagy is an evolutionary conserved pathway, by which eukaryotic cells degrade long-living cellular proteins and intracellular organelles, to maintain a pool of available nutrients. Impaired autophagy has been associated to important pathophysiological conditions, and this is the reason why several techniques have been developed for its correct assessment and monitoring. Fluorescence microscopy is one of these tools, which relies on the detection of specific fluorescence changes of targeted GFP-based reporters in dot-like organelles in which autophagy is executed. Currently, several procedures exist to count and segment this punctate structures in the resulting fluorescence images, however, they are either based on subjective criteria, or no information is available related to them. Here we present the concept of an algorithm for a semi-automatic detection and segmentation in 2D fluorescence images of spot-like structures similar to those observed under induction of autophagy. By evaluating the algorithm on more than 20000 simulated images of cells containing a variable number of punctate structures of different sizes and different levels of applied noise, we demonstrate its high robustness of puncta detection, even on a high noise background. We further demonstrate this feature of our algorithm by testing it in experimental conditions of a high non-specific background signal. We conclude that our algorithm is a suitable tool to be tested in biologically-relevant contexts.
Disruption of the interfacial membrane leads toMagnaporthe oryzaeeffector re-location and lifestyle switch during rice blast disease

Published: August 2017

ABSTRACTThe hemibiotrophic fungusMagnaporthe oryzaeproduces invasive hyphae enclosed in a plant-derived interfacial membrane, known as the extra-invasive hyphal membrane (EIHM), in living rice cells. Little is known about when the EIHM is disrupted and how the disruption contributes to blast disease. Here we show that EIHM disruption correlates with the hyphal growth stage in first-invaded susceptible rice cells. Our approach utilized GFP secreted from invasive hyphae as an EIHM integrity reporter. Secreted-GFP accumulated in the EIHM compartment but appeared in the rice cytoplasm when the EIHM integrity was compromised. Live-cell imaging of secreted-GFP and various fluorescent reporters revealed that EIHM disruption led to rice vacuole rupture and cell death limited to the invaded cell with closed plasmodesmata. We report that EIHM disruption and host cell death are landmarks delineating three distinct infection phases (early biotrophic, late biotrophic, and transient necrotrophic phases) within the first-invaded cell before reestablishment of biotrophy in second-invaded cells.M. oryzaeeffectors exhibited phase-specific localizations, including entry of the apoplastic effector Bas4 into the rice cytoplasm during the late biotrophic phase. Understanding how the phase-specific dynamics are regulated and linked to host susceptibility will offer potential targets that can be exploited to control blast disease.
Reward sensitivity following boredom and cognitive effort: A high-powered neurophysiological investigation
Authors: Milyavskaya Marina , Inzlicht Michael , Johnson Travis , Larson Michael 
Published: August 2017

AbstractWhat do people feel like doing after they have exerted cognitive effort or are bored? Here, we empirically test whether people are drawn to rewards (at the neural level) following cognitive effort and when bored. This elucidates the experiences and consequences of engaging in cognitive effort, and compares it to the consequences of experiencing boredom, an affective state with predicted similar motivational consequences. Event-related potentials were recorded after participants (N=243) were randomized into one of three conditions – boredom (observing strings of numbers), cognitive effort (adding 3 to each digit of a four-digit number), or control. In the subsequent task, we focused on the feedback negativity (FN) to assess the brain’s immediate response to the presence or absence of reward. Phenomenologically, participants in the boredom condition reported more fatigue than those in the cognitive effort condition. Results suggest participants in the boredom condition exhibited larger FN amplitude than participants in the control condition, while the cognitive effort condition was neither different from boredom nor control. The neural and methodological implications for ego depletion research, including issues of replicability, are discussed.
Diffusion of innovation among Malaysian manufacturing SMEs
Authors: Mamun Abdullah Al 
Published: August 2017

Purpose
The purpose of this paper is to examine the attributes of innovation adoption and its effects on the performance of Malaysian manufacturing SMEs.

Design/methodology/approach
Quantitative data were collected from 360 randomly selected manufacturing SMEs through structured interviews.

Findings
The findings of the study confirmed that, in Malaysian manufacturing SMEs, the degree of persuasion (i.e. relative advantages, compatibility, complexity, trialability and observability), strategic orientation (i.e. consumer, market and entrepreneurship) and firm antecedents (i.e. prior condition, knowledge and risk orientation) have significant effects on the innovation (i.e. product, process and service) adoption and performance of SMEs.

Practical implications
For policymakers, this study emphasizes the areas to focus on the development of an effective innovation ecosystem for an innovation-led economy. Because SMEs operate with limited resources and capacity, the programs and policies for innovation support systems must focus on providing new innovation information, cost-benefit analyses for new innovation adoption, innovation adoption processes and how new innovations affect performance.

Originality/value
The paper examines an important, but under-researched issue – designed and tested a model under the premises of the DOI and organizational diffusion of innovation theories which improve the knowledge and understanding about the innovation adoption by manufacturing SMEs.
Entrepreneurial intentions of young women in the Arab world
Authors: Mehtap Salime , Pellegrini Massimiliano M. , Caputo Andrea , Welsh Dianne H.B. 
Published: August 2017

Purpose
Female entrepreneurship is a growing segment in the context of developing countries and has the potential to become a driving force for economic development. However, research suggests that females are less inclined toward entrepreneurship when compared to their male counterparts. This fact is related to a complex mix of causes such as the belief that entrepreneurship is a male domain, certain conditions within the economic and social environment and a general lack of confidence with regards to succeeding in such activities. Barriers to female entrepreneurship are prevalent in the patriarchal Arab world. The purpose of this paper is to measure the perceptions of female Jordanian business students with regards to the socio-cultural barriers to entrepreneurship. It also looks at the conduciveness of the education they are receiving in terms of new venture creation.

Design/methodology/approach
A sample of 254 female business students from two universities in Jordan was asked to evaluate various factors within the entrepreneurial ecosystem, including the business education they are currently receiving. A factor analysis has been performed to show which relevant elements may prevent young women from engaging with entrepreneurial activities. A comparison of perceptions about the educational system has also been presented to understand how a supportive educational environment may affect the previous analysis.

Findings
The results indicated that a strong supportive education system to some extent may reduce the perception of potential barriers for entrepreneurship but the overall impact can be limited. Conversely, an educational system lacking a supportive environment and concrete initiatives can deeply affect and worsen the fears of engaging in entrepreneurship amongst female students.

Originality/value
The role of women in the Arab world is quite marked and the reluctance of women to take a more decisive engagement in entrepreneurship may be reinforced by conservative, societal traditions. A supportive education system has the potential to act as a catalyst to encourage active female participation in the entrepreneurial domain, thus helping to spur economic development in the region.
Helping undocumented children in an emerging Latino community
Authors: Pesantes M. Amalia , Documet Patricia I. 
Published: August 2017

Purpose
The purpose of this paper is to describe and discuss the limitations of strategies that mothers of undocumented Latino children use in an emerging community to address the health needs of their children.

Design/methodology/approach
In-depth interviews with low-income immigrant mothers of undocumented Latino children (n=10) and social service providers (n=6). Interviews were transcribed, coded using Atlas-ti and analyzed to identify common perspectives on the strategies used to secure healthcare for uninsured undocumented children.

Findings
Mothers of undocumented Latino children struggle to secure healthcare for their children. Based on the principles of familismo and personalismo, they rely on social support networks such as friends, relatives and fellow churchgoers to secure information about available healthcare options. Despite the willingness of social and health service providers to help them access healthcare, options are limited and depend on the actions of individuals rather than organized solutions. Securing care for undocumented children using families, friends and sympathetic individual providers as the source of information and advice leads to fragile unsustainable solutions.

Research limitations/implications
This paper adds to the small yet growing literature of Latinos in emerging communities.

Practical implications
Emerging Latino communities are usually unprepared to welcome Latinos and address its various needs. Undocumented children are a particularly vulnerable group and any sustainable strategy to address their needs would require structural changes in existing health services to ensure that undocumented children’s lives are not affected by poor health.

Originality/value
Healthcare access problems for immigrant children are presented from the perspective of parents and offers a nuanced description of health systems unpreparedness to provide care for vulnerable groups whose immigrant status is poorly understood.
To what extent does need for touch affect online perceived quality?
Authors: San-Martín Sonia , González-Benito Óscar , Martos-Partal Mercedes 
Published: August 2017

PurposeThe purpose of this paper is to address the potential impact of need for touch (NFT) on perceived product quality and the possible roles of purchasers’ social (subjective norms), personal (buying impulsiveness) and epistemic (e-commerce orientation) factors, as well as the likely interaction effect of the shopping channel.Design/methodology/approachThe empirical study is based on 540 observations, analysed in a partial least squares structural equation model.FindingsThe link between the NFT and perceived quality tends to be negative, especially for online purchases. E-commerce orientation reduces the need to touch products, but subjective norms and buying impulsiveness have no significant effects.Research limitations/implicationsThe NFT scale might be improved by adding more items. Some of the structural model coefficients indicate a low effect size. Finally, the results are limited to Spanish purchasers of the focal product.Practical implicationsFirms should appeal to purchasers’ e-commerce orientation to reduce the negative implications of a need to touch products among consumers shopping online.Originality/valueThe need to touch a product may be an obstacle to online purchases, yet few studies deal with its impact in online, relative to offline, contexts to evaluate product quality. This study also integrates personal, social and epistemic factors.

Authors: Liu Dongfeng 
Published: August 2017

PurposeThe purpose of this paper is to develop a scale to measure the legacy of psychic income associated with the Olympic Games.Design/methodology/approachUsing the 2008 Beijing Games as an example, data were collected from Beijing residents through structured questionnaires. A scale of measuring psychic income (SPI) was developed through conducting a confirmatory factor analysis (CFA) based on a sample of 375.FindingsIn the CFA estimation, a seven-factor SPI was identified with 24 pertinent items retained. This seven-factor model displays good fit to the data, construct validity, and reliability.Originality/valueDespite the importance of psychic income widely recognized in the existing literature, there has been a lack of valid scales to measure major sports events psychic income in general and Olympic psychic income in particular. This paper develops a multidimensional scale from the host community perspective, which can provide academics and local organizers with a reliable and valid tool to assess Olympic psychic income.

Authors: Sharma Ankit , Jha A.K. , Halder Arpan 
Published: August 2017

Purpose
In an industrial robotic cell, the optimal layout planning problem needs critical analysis, as it indirectly affects the manufacturing time and cost involved in the production process. This paper aims to propose a generic three-step robotic cell layout planning method and aims to enhance the adaptability of robotic manufacturing cell in small-scale industries.

Design/methodology/approach
The method uses the data generated from the point cloud modeling and simulation of the objects (machines and robot) to optimize their positions and orientations in the cell. The simulated annealing algorithm has been used to solve the optimization problem with minimum joint displacement criterion. This approach is critically analyzed and discussed against the data collected from an industrial robotic cell in a foundry shop of a pipe manufacturing industry.

Findings
More than 50 per cent reduction in the net joint movement of the robot has been achieved. Immediate feedback of the results by a three-dimensional view of the optimal cell layout without using any commercial robotic simulation package.

Originality/value
The layout optimization of an industrial robotic cell based on the point cloud modeling of its objects is the novelty of the method.
Integration of fault tree analysis, reliability block diagram and hazard decision tree for industrial robot reliability evaluation
Authors: Fazlollahtabar Hamed , Akhavan Niaki Seyed Taghi 
Published: August 2017

Purpose
This paper aims to conduct a comprehensive fault tree analysis (FTA) on the critical components of industrial robots. This analysis is integrated with the reliability block diagram (RBD) approach to investigate the robot system reliability.

Design/methodology/approach
For practical implementation, a particular autonomous guided vehicle (AGV) system was first modeled. Then, FTA was adopted to model the causes of failures, enabling the probability of success to be determined. In addition, RBD was used to simplify the complex system of the AGV for reliability evaluation purpose.

Findings
Hazard decision tree (HDT) was configured to compute the hazards of each component and the whole AGV robot system. Through this research, a promising technical approach was established, allowing decision-makers to identify the critical components of AGVs along with their crucial hazard phases at the design stage.

Originality/value
As complex systems have become global and essential in today’s society, their reliable design and determination of their availability have turned into very important tasks for managers and engineers. Industrial robots are examples of these complex systems that are being increasingly used for intelligent transportation, production and distribution of materials in warehouses and automated production lines.
The vibratory alignment of the parts in robotic assembly
Authors: Baksys Bronius , Baskutiene Jolanta , Baskutis Saulius 
Published: August 2017

Purpose
This paper aims to consider the experimental and theoretical investigation of the vibratory alignment of the peg-hole, when the peg is fixed in the remote centre compliance (RCC) device, and the vibrations are provided either to the hole or to the peg.

Design/methodology/approach
The experimental analysis of the circular and rectangular peg-hole vibratory alignment using the attached to the robot arm RCC device, under vibratory excitation of the hole, has been performed. The parameters of the vibratory excitation and the part-to-part pressing force influence on the alignment process have been analysed. The mathematical approach of the vibratory alignment using the passive compliance device with the vibrations provided to the peg has been proposed, and the simulation has been carried out.

Findings
The research has approved the applicability of the RCC device for both of the vibratory alignments of the non-chamfered peg-hole parts either circular or rectangular ones. The compensation of the axial misalignments has been resulted by the directional displacement of the peg supported compliantly. To perform the successful alignment of the parts, it has been necessary to adjust the frequency and the amplitude of the vibrations, the pressing force, the lateral, as well as the angular stiffness of the device.

Research limitations/implications
The experiments on the vibratory alignment of the rectangular peg-hole parts have been carried out considering only the translational misalignment moved into one direction. The non-impact regime of the vibratory alignment has been analysed.

Practical implications
The obtained results can be applied in designing the reliable and efficient devices of the vibratory assembly for the alignment of the non-chamfered peg-hole parts, as well as for chamfered ones, if the axial misalignment exceeds the width of the chamfer. The vibratory technique and passive compliance provide possibility to accomplish the assembly operations using the non-expensive low accuracy robots.

Originality/value
The new method and the mathematical approach of the vibratory assembly using the RCC device can ensure the reliable alignment of the non-chamfered parts, chamfered circular and the rectangular ones, in case the axial misalignment exceeds the assembly clearance, and prevent jamming and wedging.
Comparative study between IFRS and AAOIFI disclosure compliance
Authors: Ajili Hana , Bouri Abdelfettah 
Published: August 2017

Purpose
This study measures and compares the level of compliance with the disclosure requirements provided by the International Financial Reporting Standards (IFRS) and the Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI). This study also aims to investigate the factors associated with this compliance in a sample of Islamic banks (IBs) in Gulf Cooperation Council member states.

Design/methodology/approach
The sample consists of 39 IBs between 2010 and 2014. Among the selected IBs, 23 banks were complying with the AAOIFI standards and 16 banks were complying with the IFRS standards. An unweighted disclosure index was used to measure the level of compliance with IFRS/AAOIFI disclosure requirements.

Findings
It was found that the level of compliance with IFRS is higher than that of compliance with AAOIFI. In addition, the results reveal that compliance with IFRS/AAOIFI disclosure requirements is higher for larger and older IBs. Finally, it was observed that compliance was more noticeable for IBs having a higher leverage and multinational subsidiaries.

Originality value
These findings would be of great help to regulators and policymakers to better understand the accounting disclosure practices of IBs.
