Organizational emphasis on inclusion as a cultural value and third-party response to sexual harassment
Authors: Collazo Jr José Luis , Kmec Julie A. 
Published: September 2018

PurposeReliance on third-party judgments are common in efforts to identify and reduce workplace sexual harassment (SH). The purpose of this paper is to identify whether a workplace emphasis on inclusion as a cultural value is related to third-party labeling of and response to an exchange between a male manager and his female subordinate.Design/methodology/approachParticipants (n=308) in an online survey experiment were randomly assigned to a workplace that emphasized inclusion or one that emphasized individual achievement as a cultural value. They read a vignette describing a workplace interaction between a male manager and his female subordinate and responded to a series of questions.FindingsOrganizational emphasis on inclusion is unrelated to third-party labeling of the interaction as SH, but positively associated with labeling the female’s intention to pursue harassment charges as an overreaction, and support for the female subordinate in a claim of SH against her manager. Culture is unassociated with willingness to defend the male manager in a SH claim.Practical implicationsIdentifying how workplace culture shapes third-party reaction to harassment can help employers use third-party witnesses and cultural value statements as tools to reduce SH.Social implicationsA workplace’s cultural emphasis on inclusion is positively related to third-party support for SH victims implying the importance of workplace context in the fight against workplace SH.Originality/valueThe paper presents the first experimental analysis of how a workplace cultural emphasis on inclusion affects the third-party observers’ reactions to SH.
Big Data analytics for prediction: parallel processing of the big learning base with the possibility of improving the final result of the prediction
Authors: Djafri Laouni , Amar Bensaber Djamel , Adjoudj Reda 
Published: September 2018

PurposeThis paper aims to solve the problems of big data analytics for prediction including volume, veracity and velocity by improving the prediction result to an acceptable level and in the shortest possible time.Design/methodology/approachThis paper is divided into two parts. The first one is to improve the result of the prediction. In this part, two ideas are proposed: the double pruning enhanced random forest algorithm and extracting a shared learning base from the stratified random sampling method to obtain a representative learning base of all original data. The second part proposes to design a distributed architecture supported by new technologies solutions, which in turn works in a coherent and efficient way with the sampling strategy under the supervision of the Map-Reduce algorithm.FindingsThe representative learning base obtained by the integration of two learning bases, the partial base and the shared base, presents an excellent representation of the original data set and gives very good results of the Big Data predictive analytics. Furthermore, these results were supported by the improved random forests supervised learning method, which played a key role in this context.Originality/valueAll companies are concerned, especially those with large amounts of information and want to screen them to improve their knowledge for the customer and optimize their campaigns.
Exploring the benefits and challenges of learning analytics in higher education institutions: a systematic literature review
Authors: El Alfy Shahira , Marx Gómez Jorge , Dani Anita 
Published: September 2018

Purpose
The potential capabilities and benefits that learning analytics can provide are not fully utilized. A current stream of research suggests that learning analytics has more to offer for continuous improvement of higher education institutions. This study aims to explore the opportunities that data analytics stand to offer higher education and the challenges that plays down its role, adoption and usage in different areas of higher education institutions.

Design/methodology/approach
This study adopts a systematic literature review approach in answering the research questions. The critical role of learning analytics and the exploratory nature of research questions justify the use of systematic literature review. The current study used systematic research process adapted and presented by Hallinger (2013) to be used in social sciences in general and in educational leadership and management in particular. A standard process of finding relevant articles and examining reference lists is followed using articles from higher education which is the research context.

Findings
An examination of the literature showed that the majority of studies within the sample of articles are empirical representing 53 per cent, 32 per cent are conceptual, while only 15 per cent of the articles are a systematic literature review. Results also show that 58 per cent of the articles are teaching and learning related, 34 per cent are management related, while only 8 per cent are research related. Several challenges and opportunities of learning analytics in the three areas highlighted are presented and discussed.

Originality/value
The benefits and challenges of learning analytics are numerous and scattered in the literature. In this study, a typology related to different educational domains is developed to shed light on the benefits and challenges of learning analytics within particular higher education areas that are relevant to specific stakeholders. Benefits and challenges of learning analytics are classified into being management related, teaching and learning related and research related.
Family policies and fertility
Authors: Wesolowski Katharina , Ferrarini Tommy 
Published: September 2018

Purpose
The purpose of this paper is to analyze the link between two different family policy dimensions – one supporting the combination of work and parenthood and one supporting stay-at-home mothers – and fertility rates between 1995 and 2011 in 33 industrialized countries.

Design/methodology/approach
Total fertility rates were regressed on the two policy dimensions, earner–carer support and traditional–family support, using pooled time-series analysis with country fixed effects and stepwise control for female labor force participation, unemployment rates and GDP.

Findings
The analyses show that earner–carer support is linked to higher fertility, while traditional–family support is not. Also, higher female labor force participation is linked to higher fertility before GDP is included. Conversely, higher unemployment is correlated with lower fertility levels. Sensitivity analyses with and without day care enrollment on a smaller set of countries show no influence of day care on the results for family policy.

Originality/value
The results give weight to the argument that family policies supporting the combination of work and parenthood could increase fertility in low-fertility countries, probably mediated in part by female labor force participation. Earnings-related earner–carer support incentivizes women to enter the labor force before parenthood and to return to work after time off with their newborn child, thus supporting a combination of work and parenthood.

Published: September 2018

PurposeThe purpose of this paper is to provide empirical evidence of the relationship between end-user computing satisfaction (EUCS) and radical innovation, using organizational learning as an explanatory variable.Design/methodology/approachAn empirical study was conducted in a population of 402 Spanish companies. A sample of 251 valid questionnaires was obtained. Structural equations were used to validate the proposed hypotheses.FindingsOrganizational learning capability fully mediates the relationship between EUCS and radical innovation.Research limitations/implicationsThe sample of companies is heterogeneous in terms of size, sector, age and market share. The study uses single informants.Practical implicationsResults highlight the need to implement adequate information systems to promote radical innovation. In addition, it is necessary to facilitate organizational contexts that encourage dialogue, experimentation, risk-taking, participative decision-making and openness to the external environment.Originality/valueThis research contributes to the study of alternative antecedents of radical innovation by highlighting the importance of EUCS.
Effect of labelled information and sensory attributes on consumers’ intention to purchase milk
Authors: Hoque Mohammed Ziaul , Xie Jinghua , Nazneen Suraiya 
Published: September 2018

PurposeThe purpose of this paper is to examine the influences of consumer perceptions of labelled information and sensory attributes on consumers’ intention to buy fresh milk.Design/methodology/approachAn experiment was conducted on 117 consumers in a lab at a university. After closely inspecting the labels’ information and tasting two types of milk, participants were asked to fill in a questionnaire, using the direct interview method. Exploratory factor analysis, confirmatory factor analysis and structural equation modelling were applied to analyse the data.FindingsThe results show that products’ labelled information and the sensory perceptions increase the buying intention of both ultra-high temperature treated fresh milk (UFM) and pasteurised fresh milk (PFM). The sensory perceptions of PFM can mediate the relationship between products’ labels and consumer buying intentions, but this relationship is not true for UFM. According to our results, nutritional facts and taking responsibility for one’s health are the keys to fresh milk commercialisation in terms of higher relative weights and commonness.Originality/valueAlthough the sensory aspects of milk have been rigorously evaluated in the food science literature, to the best of the authors’ knowledge, few studies have focussed on the sensory perceptions of fresh milk incorporating process categories (UFM and PFM) and their mediating effect between labelled information and buying intention in the social sciences. The study is pioneering in that it investigates the perceptions of sensory attributes affecting consumer purchasing decisions for fresh milk in an emerging market.
Organizational learning as participants’ knowledge harvesting from product development
Authors: Tolsby June 
Published: September 2018

Purpose
This paper aims to introduce the term, knowledge harvesting, as an aid for researchers in comprehending what knowledge strategies influences projects, where to find knowledge, how to visualize knowledge, how to cultivate knowledge, who distributes project knowledge and how to gain former project knowledge.

Design/methodology/approach
The term knowledge harvesting emerged after having analyzed employees interviews at a Danish welding machine manufacturer using an adjusted grounded theory.

Findings
Employees’ knowledge harvesting strategies involve collecting knowledge, making knowledge visible in projects, introducing knowledge in projects, identifying knowledge deficiencies, cultivating knowledge to support projects and ensuring readily available historical knowledge termed para-knowledge.

Practical implications
To strengthen how significant and relevant knowledge harvesting can be, researchers need to apply knowledge harvesting as an explanation in their own research projects. Only then will knowledge harvesting becomes a solid explanation of what knowledge strategies employees apply and their implications for organization learning.

Originality/value
Knowledge harvesting introduces new understandings regarding employees’ knowledge acquisition processes during product development. Knowledge harvesting can help researchers to understand and identify how, why and what knowledge processes take place throughout product development.
Preparation and characterization of transparent magneto‐optical Ho2O3 ceramics
Authors: Lu Bin , Cheng Hongmei , Xu Xinxin , Chen Hongbing 
Published: September 2018

AbstractTransparent magneto‐optical Ho2O3 ceramics were successfully prepared with an in‐line transmittance of ~73% at the wavelength of 1000 nm (~90% of the theoretical transmittance of Ho2O3 single crystal) and an average grain size of ~28 μm. The ceramics were fabricated using sulfate‐exchanged nitrate‐type layered rare‐earth hydroxide as the precipitation precursor at a relatively low sintering temperature of 1700°C. The layered compound exhibited nanosheet morphology and fully collapsed into a round oxide powder with an average particle size of ~48 nm by pyrolysis. Calcination temperature for Ho2O3 powder significantly affected the optical quality of the sintered body and the optimum calcination temperature was found to be 1050°C. The transparent magneto‐optical Ho2O3 ceramics displayed wavelength‐dependent Verdet constants of −180, −46, and −20 rad/Tm at 632, 1064, and 1550 nm, respectively. Thus, the Ho2O3 ceramics show good potential for applications in high‐power laser systems.

Published: September 2018

AbstractZnS has been found superiority in photoelectrochemistry for the fast response of photo‐inducing and its high conductor band position (~0.8 eV) results in strong reduction ability for hydrogen production. However, the solar absorbance of ZnS is much low for the wide band gap (~3.2 eV) and the carriers’ migration efficiency also need to be improved. Here, nano‐ZnS were coupled with ultrathin SnS2 nanosheets as heterojunction composites. This heterojunction composite demonstrated largely increase in specific surface area (from 4 to 12‐25 m2/g), obvious improvement of UV‐vis absorbance and narrower band gap. Furthermore, the carriers’ migration efficiency of ZnS/SnS2 heterojunction has been confirmed to be much higher by photocurrent response and electrochemical impedance spectroscopy. Due to the improvement in structure, compared with pristine ZnS, this ZnS/SnS2 heterojunction exhibited vast enhancement in photoelectrochemical performance. The composite with best activity exhibited 12.8 times enhancement in photocurrent density. The conduction band and valence band of ZnS are both more negative than those of SnS2, the photo‐induced electrons at the conduction band of ZnS will transfer into the conduction band of SnS2 while the photo‐induced holes at the valence band of SnS2 will transfer into the valence band of ZnS. In this way, the photo‐produced carriers will flow into different semiconductors and the carriers’ migration efficiency is enhanced. The work improves a new structure to develop the heterojunction property for photoelectrochemical application.

Published: September 2018

ABSTRACTBACKGROUND AND PURPOSETeriflunomide reduces disability progression and brain atrophy in multiple sclerosis patients. The exact mechanism of action by which teriflunomide exerts these effects is currently unknown. We assessed the effect of teriflunomide on brain glial cells in the Theiler's murine encephalomyelitis virus (TMEV) by using a histological approach in combination with neuroimaging.METHODSForty‐eight SJL female mice received an intracerebral injection of TMEV at 6–8 weeks of age and were then treated with teriflunomide (n = 24) or placebo (n = 24) for 9 months. They were examined with MRI and behavioral testing at 2, 6, and 9 months postinduction (mPI). Of those, 18 teriflunomide‐treated and 17 controls mice were analyzed histologically at 9 mPI to sample from different brain regions for myelination status, microglial density, and oligodendroglial lineage. The histological and MRI outcomes were correlated.RESULTSCorpus callosum microglial density was numerically lower in the teriflunomide‐treated mice compared to the control group (141.1 ± 21.7 SEM vs. 214.74 ± 34.79 SEM, Iba1+ cells/mm2, P = .087). Basal ganglia (BG) microglial density in the teriflunomide group exhibited a negative correlation with fractional anisotropy (P = .021) and a positive correlation with mean diffusivity (P = .034), indicating less inflammation and axonal damage. Oligodendroglial lineage cell and myelin density were not significantly different between treatment groups. However, a significant positive correlation between BG oligodendrocytes and BG volume (P = .027), and with N‐acetyl aspartate concentration (P = .008), was found in the teriflunomide group, indicating less axonal loss.CONCLUSIONTeriflunomide altered microglia density and oligodendrocytes differentiation, which was associated with less evident microstructural damage on MRI.
Short‐term and long‐term human or mouse organoid units generate tissue‐engineered small intestine without added signalling molecules

New Findings
What is the central question of this study?
Tissue‐engineered small intestine was previously generated in vivo by immediate implantation of organoid units derived from both mouse and human donor intestine. Although immediate transplantation of organoid units into patients shows promise as a potential future therapy, some critically ill patients might require delayed transplantation.

What is the main finding and its importance?
Unlike enteroids, which consist of isolated intestinal crypts, short‐ and long‐term cultured organoid units are composed of epithelial and mesenchymal cells derived from mouse or human intestine. Organoid units do not require added signalling molecules and can generate tissue‐engineered intestine in vivo.

AbstractMouse and human postnatal and fetal organoid units (OUs) maintained in either short‐term culture (2 weeks) or long‐term culture (from 4 weeks up to 3 months) without adding exogenous growth factors were implanted in immunocompromised mice to form tissue‐engineered small intestine (TESI) in vivo. Intestinal epithelial stem and neuronal progenitor cells were maintained in long‐term OU cultures from both humans and mice without exogenous growth factors, and these cultures were successfully used to form TESI. This was enhanced with OUs derived from human fetal tissues. Organoid unit culture is different from enteroid culture, which is limited to epithelial cell growth and requires supplementation with R‐Spondin, noggin and epidermal growth factor. Organoid units contain multiple cell types, including epithelial, mesenchymal and enteric nervous system cells. Short‐ and long‐term cultured OUs derived from mouse and human intestine develop into TESI in vivo, which contains key components of the small intestine similar to native intestine.
Bacterial antagonism in host-associated microbial communities
Authors: García-Bayona Leonor , Comstock Laurie E. 
Published: September 2018

Interspecies competition shapes communities
The gut microbiota of mammals is diverse and dynamic, and gut bacteria respond sensitively to diet and drug intake. Nevertheless, in a healthy adult, microbial community composition remains remarkably stable over time, despite being highly individual. García-Bayona and Comstock review the mechanisms that gut bacterial species use to jostle for space and resources and maintain their populations in the face of intense and varied competition. Bacteria have evolved a range of antibiotics, bacteriocins, toxins, and delivery devices to enable interspecies conflict. These interbacterial weapons possess a spectrum of specificities and range from those that target strains of their own species to broad-acting bacteriocides. This toxic armamentarium provides a valuable resource for potential therapeutic development.

Self-monitoring of blood glucose in insulin-treated diabetes: a multicase study
Authors: Cameron Dawn , Harris Fiona , Evans Josie M M 
Published: September 2018

ObjectiveTo explore how and why self-monitoring of blood glucose (SMBG) is carried out in a real-world context.Research design and methodsWe conducted a multicase study among ten people with type 1 and insulin-treated type 2 diabetes mellitus in Scotland, alongside seven nominated support people and four healthcare professionals. All participants were interviewed in depth and six participants provided SMBG diaries. Stones’ version of structuration theory informed the analysis.ResultsPeople with diabetes were able to provide immediate motives for SMBG at particular times, often having different motives on different occasions. We identified six such motives, including routine, in response to symptoms, associated with a diabetes review, to facilitate lifestyle, when a ‘good’ result was expected, and higher level motives for longer term glycemic control. These motives were influenced by underlying attitudes toward diabetes that included level of engagement and responsibility for diabetes, a desire not to be controlled by diabetes, resistance to diabetes, diabetes education and relationship with the health service, fear of hypoglycemia, and prevention of diabetes complications. Five responses to test results were identified, depending on the immediate motive and underlying attitudes.ConclusionsPeople with insulin-treated diabetes do not necessarily self-monitor with an explicit goal of improving long-term glycemic control, but may have other motives that are important to them. An individualized understanding is therefore needed to advise people with diabetes how SMBG can be optimized for them.
