Authors: Aharony Noa , Gazit Tali 
Published: June 2019

PurposeThe purpose of this paper is to explore how computer self-efficacy (CSE), perceived information overload (IO) and the digital native perspective predict students’ information literacy (IL) self-efficacy.Design/methodology/approachThe research was conducted in Israel and comprised 117 students from the Information Science Department at Bar-Ilan University. Researchers used five questionnaires to gather personal details: a demographic questionnaire, the IL self-efficacy questionnaire, the CSE questionnaire, technology usage (TU) questionnaire and the perceived IO questionnaire.FindingsThe findings confirm that these variables significantly predict students’ IL self-efficacy.Originality/valueInstructors and librarians should be familiar with the issue of individual differences, as well with the issue of students’ age. These factors may help them choose the most appropriate way when instructing IL skills to their students.
Entrepreneurial university strategies in the UK context: towards a research agenda
Authors: Pickernell David , Ishizaka Alessio , Huang Shuangfa , Senyard Julienne 
Published: June 2019

Purpose
Prior research shows that universities differ in the knowledge exchange (KE) activities they pursue, but little is known about universities’ strategies regarding their portfolio of KE activities. The purpose of this paper is to explore the KE strategy of UK universities in specific relation to their portfolio of KE activities with small- and medium-sized enterprises.

Design/methodology/approach
Based on the 2015–2016 Higher Education Business and Community Interaction Survey data set, this study employs the Preference Ranking Organisation METHod for the Enrichment of Evaluations to assess the KE activities from 162 UK higher education institutions.

Findings
The study reveals that entrepreneurial universities valorise university knowledge assets through five SME-focussed KE activities most beneficial to measuring the entrepreneurial university. It also uncovers four different archetypal categories (groupings) of universities based on their strategic focus of KE activities.

Originality/value
This study contributes to the entrepreneurial university literature by considering universities’ overall KE portfolio rather than examining individual KE activity in isolation. It provides a clearer understanding of universities’ KE strategies that help define and delineate entrepreneurial universities regarding their range, focus and the combination of KE activities.
Construction resource allocation for industrial solid waste treatment centers in cities of Anhui Province, China
Authors: Wu Jie , Zhang Wanting , Zhou Zhixiang 
Published: June 2019

Purpose
The purpose of this paper is to study where to place industrial solid waste treatment centers among the 16 prefecture-level cities under its jurisdiction.

Design/methodology/approach
This paper adopts the cross-efficiency data envelopment analysis (DEA) model, with the industrial land price and average annual salary per capita as inputs, while coverage, total transportation distance, number of industrial enterprises and total amount of industrial solid waste are used as outputs.

Findings
Based on the spatial efficiency scores calculated by using the new presented models, the authors find that the most efficient construction site are Chizhou, Chuzhou, Suzhou and Bengbu. That is quite different from the results obtained by using traditional approach.

Originality/value
This paper evaluates the spatial efficiency by using combinations of the four locations as the decision-making units of the DEA model, which could be used as an objective way to allocate limited resource. In addition to the resource allocation of the industrial solid waste treatment center, the method in this paper can also be applied to other spatial aspects of resource allocation.
Hybrid production system: perspectives in supply chain risk management
Authors: Wolfshorndl Diego Aparecido , Vivaldini Mauro , Camargo Junior João Batista de 
Published: June 2019

PurposeFrom the perspective of the supply chain risk management (SCRM), this paper addresses the effects of a hybrid production system (make-to-stock and make-to-order) in order to know which risks can impact the production planning process at a large automaker in Brazil. Through the correlation of these themes, the purpose of this paper is to understand the relevant risks to the supply chain (SC).Design/methodology/approachBefore the field research, a theoretical approach was made on two themes. After theoretical analysis of a case study on the automaker and data collection, the work used the Pearson’s product moment correlation (r) andχ2and Kolmogorov–Smirnov tests to assess the risk factors raised by the interviewed professionals, thus characterizing a mixed methodological approach (i.e. qualitative and quantitative).FindingsIt was evidenced that many risks are the result of functional failures, such as input of incorrect information in the system, and many are inherent to managerial decisions when procedures and different paths of production are adopted. Additionally, it has been proven that the adoption of a hybrid production planning approach does not increase the risks to the SC and that the identified risks do not necessarily are included within the scope of SCRM.Originality/valueThis study is characterized by an approach which combines SCRM and hybrid production system.
Experimental approach to thermal conductivity of macro solder joints with voids
Authors: Sobolewski Maciej , Dziurdzia Barbara 
Published: June 2019

Purpose
The purpose of the paper is to experimentally evaluate the impact of voids on thermal conductivity of a macro solder joint formed between a copper cylinder and a copper plate by using reflow soldering.

Design/methodology/approach
A model of a surface mount device (SMD) was developed in the shape of a cylinder. A copper plate works as a printed circuit board (PCB). The resistor was connected to a power supply and the plate was cooled by a heat sink and a powerful fan. A macro solder joint was formed between a copper cylinder and a copper plate using reflow soldering and a lead-free solder paste SAC305. The solder paste was printed on a plate through stencils of various apertures. It was expected that various apertures of stencils will moderate the various void contents in solder joints. K-type thermocouples mounted inside cylinders and at the bottom of a plate underneath the cylinders measured the temperature gradient on both sides of the solder joint. After finishing the temperature measurements, the cylinders were thinned by milling to thickness of about 2 mm and then X-ray images were taken to evaluate the void contents. Finally the tablets were cross-sectioned to enable scanning electron microscopy (SEM) observations.

Findings
There was no clear dependence between thermal conductivity of solder joints and void contents. The authors state that other factors such as intermetallic layers, microcracks, crystal grain morfologyof the interface between the solder and the substrate influence on thermal conductivity. To support this observation, further investigations using metallographic methods are required.

Originality/value
Results allow us to assume that the use of SAC305 alloy for soldering of components with high thermal loads is risky. The common method for thermal balance calculation is based on the sum of serial thermal resistances of mechanical compounds. For these calculations, solder joints are represented with bulk SAC305 thermal conductivity parameters. Thermal conductivity of solder joints for high density of thermal energy is much lower than expected. Solder joints’ structure is not fully comparable with bulk SAC305 alloy. In experiments, the average value of the solder joint conductivity was found to be 8.1 W/m·K, which is about 14 per cent of the nominal value of SAC305 thermal conductivity.

Published: June 2019

SummarySpecies in the archaeal order Sulfolobales thrive in hot acid and exhibit remarkable metabolic diversity. Some species are chemolithoautotrophic, obtaining energy through the oxidation of inorganic substrates, sulphur in particular, and acquiring carbon through the 3‐hydroxypropionate/4‐hydroxybutyrate (3‐HP/4‐HB) CO2‐fixation cycle. The current model for sulphur oxidation in the Sulfolobales is based on the biochemical analysis of specific proteins from Acidianus ambivalens, including sulphur oxygenase reductase (SOR) that disproportionates S° into H2S and sulphite (SO32−). Initial studies indicated SOR catalyses the essential first step in oxidation of elemental sulphur, but an ancillary role for SOR as a ‘recycle’ enzyme has also been proposed. Here, heterologous expression of both SOR and membrane‐bound thiosulphate‐quinone oxidoreductase (TQO) from Sulfolobus tokodaii ‘restored’ sulphur oxidation capacity in Sulfolobus acidocaldarius DSM639, but not autotrophy, although earlier reports indicate this strain was once capable of chemolithoautotrophy. Comparative transcriptomic analyses of Acidianus brierleyi, a chemolithoautotrophic sulphur oxidizer, and S. acidocaldarius DSM639 showed that while both share a strong transcriptional response to elemental sulphur, S. acidocaldarius DSM639 failed to upregulate key 3‐HP/4‐HB cycle genes used by A. brierleyi to drive chemolithoautotrophy. Thus, the inability for S. acidocaldarius DSM639 to grow chemolithoautotrophically may be rooted more in gene regulation than the biochemical capacity.
Transcriptional regulation of central carbon metabolism in Pseudomonas aeruginosa
Authors: Dolan Stephen K. , Pereira Greicy , Silva‐Rocha Rafael , Welch Martin 
Published: June 2019

SummaryMicrobes such as Pseudomonas aeruginosa are often challenged by rapidly changing nutritional environments. In order to adapt to these shifts in nutrient availability, bacteria exert tight transcriptional control over the enzymes of central metabolism. This transcriptional control is orchestrated by a series of transcriptional repressors and activators. Although a number of these transcription factors have been identified, many others remain uncharacterized. Here, we present a simple pipeline to uncover and validate the targets of uncharacterized transcriptional regulators in P. aeruginosa. We use this approach to identify and confirm that an orthologue of the Pseudomonas fluorescens transcriptional regulator (RccR) binds to the upstream region of isocitrate lyase (aceA) in P. aeruginosa, thereby repressing flux through the glyoxylate shunt during growth on non‐C2 carbon sources.

Published: June 2019

BackgroundPrevious studies have documented a high incidence of toxicity in patients with ultra‐central non‐small cell lung cancer (UC‐NSCLC) treated with stereotactic body radiation therapy (SBRT). However, these studies mainly focused on early stage patients and included small sample populations. We reviewed the outcomes and toxicity of SBRT in patients with advanced stage UC‐NSCLC treated at our institution.MethodsFifty‐one consecutive patients with advanced UC‐NSCLC treated with SBRT using a regular regimen of 35 Gy administered in five fractions between December 2014 and August 2017 were reviewed. UC was defined as tumors abutting or overlapping the trachea or the proximal bronchial tree. We included locally advanced patients who were unfit or unwilling to receive conventional chemoradiotherapy and patients with metastatic or postoperative recurrent disease. Clinical outcomes, dosimetric parameters, and SBRT toxicity were analyzed.ResultsThe median age was 63 years (range: 35–82), and the median tumor diameter was 6.8 cm (range: 2.1–12.4). The overall median follow‐up duration was 17 months (25.5 months for surviving patients). The median local control was 17 months for stage III patients and 11 months for stage IV or recurrent patients. Grade 3 or higher toxicity was observed in 9.8% of patients: G3 radiation pneumonitis (5.9%) and possible treatment‐related death (3.9%).ConclusionSBRT with a moderate dose in 4–6 fractions is effective and tolerable for patients with advanced stage UC‐NSCLC. However, caution should be taken considering possible treatment‐related death. Further studies are warranted.
Renormalized basal metabolic rate describes the human aging process and longevity

Published: June 2019

AbstractThe question of why we age and finally die has been a central subject in the life, medical, and health sciences. Many aging theories have proposed biomarkers that are related to aging. However, they do not have sufficient power to predict the aging process and longevity. We here propose a new biomarker of human aging based on the mass‐specific basal metabolic rate (msBMR). It is well known by the Harris–Benedict equation that the msBMR declines with age but varies among individual persons. We tried to renormalize the msBMR by primarily incorporating the body mass index into this equation. The renormalized msBMR (RmsBMR) which was derived in one cohort of American men (n = 25,425) was identified as one of the best biomarkers of aging, because it could well reproduce the observed respective American, Italian, and Japanese data on the mortality rate and survival curve. A recently observed plateau of the mortality rate in centenarians corresponded to the lowest value (threshold) of the RmsBMR, which stands for the final stage of human life. A universal decline of the RmsBMR with age was associated with the mitochondrial number decay, which was caused by a slight fluctuation of the dynamic fusion/fission system. This decay form was observed by the measurement in mice. Finally, the present approach explained the reason why the BMR in mammals is regulated by the empirical algometric scaling law.
Rethinking learning? Challenging and accommodating neoliberal educational agenda in the integration of Forest School into mainstream educational settings
Authors: Pimlott‐Wilson Helena , Coates Janine 
Published: June 2019

A nation's education system plays a key role in future economic competitiveness. Political attention to education has fuelled geographical interest in the role of formal education and informal learning environments in the cultivation of future citizen‐workers. To date, formal and informal learning have largely been considered separately, but this paper responds by critically evaluating the intersections between the two spheres. This agenda is pursued through in‐depth analysis of two state‐funded, mainstream primary schools in the Midlands, UK, which adopt a Forest School programme. Qualitative in nature, the research involved 37 semi‐structured interviews with teachers and children in the Reception class and Year 4 (ages four to five, and eight to nine, respectively). The findings demonstrate that children understand classroom learning to contribute to their future pathways in a credentialised labour market, yet some struggle to frame Forest School activities as educational. Although presented as an antidote to the regimen of the school day, Forest School can thus be justified by some participants in relation to curriculum alignment and the future efficacy of the skills and knowledge acquired. In conclusion, this paper contributes to debates on the intersections of formal and informal education to examine how alternative education can function to counteract the institutionalisation of mainstream settings, while paradoxically developing skills in children that are valued by neoliberal states. More broadly, this furthers debates in geographies of education about what constitutes valuable learning in the primary school setting, and draws attention to the ways innovations might further exclude children currently disadvantaged in the education system.
Mindfulness‐based practices with family carers of adults with learning disability and behaviour that challenges in the UK: Participatory health research
Authors: Cook Tina , Noone Steven , Thomson Megan 
Published: June 2019

AbstractBackgroundFamily carers of adults with learning disability and behaviours that challenge lead complex and stressful lives. Their caring role can leave them isolated and unsupported. In the UK, effective services designed to build resilience for people in long‐term caring roles are lacking. There are none (to our knowledge) designed using a participatory health research (PHR) approach with family carers and professionals.ObjectiveWith positive behaviour support (PBS) and mindfulness and acceptance and commitment therapy (ACT) as key elements, a PHR approach was used to understand the basis for a successful course that supported the capabilities and resilience of family members in long‐term caring roles.DesignThe research was guided by the principles of PHR with participation as the defining principle throughout. Central to the research were reflexive conversations (communicative spaces) where diverse knowledges were shared and critiqued.FindingsMindfulness/ACT can change long‐standing response behaviours and build personal resilience and improve mental health. Elements enabling positive change included a facilitation approach for collaborative reflexivity and the complementary, interactive approach to collaborative enquiry for learning and decision making afforded by PHR.DiscussionThe use of PHR accessed knowledges that would have been lost to more traditional, professional‐expert driven processes and facilitated change in constructs for action for both professionals and family carers. Findings challenge service providers to consider how experiential knowledge has agency in professional practice and service design. Reflection on the PHR process across the FaBPos project led to a re‐consideration of quality issues in relation to PHR and participation.

AbstractBackgroundNavigating treatment pathways remains a challenge for populations with complex needs due to bottlenecks, service gaps and access barriers. The application of novel methods may be required to identify and remedy such problems.ObjectiveTo demonstrate a novel approach to identifying persistent service gaps, generating potential solutions and prioritizing action.DesignCo‐creation and multi‐criteria decision analysis in the context of a larger, mixed methods study.Setting and participantsCommunity‐dwelling sample of older women living alone (OWLA), residing in Melbourne, Australia (n = 13‐37). Convenience sample of (n = 11) representatives from providers and patient organizations.InterventionsNovel interventions co‐created to support health, well‐being and independence for OWLA and bridge missing links in pathways to care.Main outcome measuresPerformance criteria, criterion weights , performance ratings, summary scores and ranks reflecting the relative value of interventions to OWLA.ResultsThe co‐creation process generated a list of ten interventions. Both OWLA and stakeholders considered a broad range of criteria when evaluating the relative merits of these ten interventions and a “Do Nothing” alternative. Combining criterion weights with performance ratings yielded a consistent set of high priority interventions, with “Handy Help,” “Volunteer Drivers” and “Exercise Buddies” most highly ranked by both OWLA and stakeholder samples.Discussion and conclusionsThe present study described and demonstrated the use of multi‐criteria decision analysis to prioritize a set of novel interventions generated via a co‐creation process. Application of this approach can add community voice to the policy debate and begin to bridge the gap in service provision for underserved populations.
Assessing similarity of n‐dimensional hypervolumes: Which metric to use?
Authors: Mammola Stefano 
Published: June 2019

AbstractAimThe n‐dimensional hypervolume framework (Glob. Ecol. Biogeogr. [2014] 23:595–609) implemented through the R package 'hypervolume' is being increasingly used in ecology and biogeography. This approach offers a reliable means for comparing the niche of two or more species, through the calculation of the intersection between hypervolumes in a multidimensional space, as well as different distance metrics (minimum and centroid distance) and niche similarity indexes based on volume ratios (Sørensen–Dice and Jaccard similarity). However, given that these metrics have conceptual differences, there is still no consensus on which one(s) should be routinely used in order to assess niche similarity. The aim of this study is to provide general guidance for constructing and comparing n‐dimensional hypervolumes.LocationVirtual study site.TaxonVirtual species.MethodFirst, the literature was screened to verify the usage of the different metrics in studies (2014–2018) relying on this method. Subsequently, a comparative analysis based on simulated morphological and bioclimatic traits was performed, taking into consideration different analytical dimensions, sample sizes and algorithms for hypervolume construction.ResultsLiterature survey revealed that there was no clear preference for one metric over the others in current studies relying on the n‐dimensional hypervolume method. In simulated data, a high correlation among similarity and distance metrics was found for all datatypes considered. For most analytical scenarios, using at least one overlap and one distance metric would be therefore the most appropriate approach for assessing niche overlap. Yet, when hypervolumes are fully disjunct, similarity metrics become uninformative and calculating the two distance metrics is recommended. The sample size and the choice of algorithm and dimensionality can lead to significant variations in the overlap of hypervolumes in the hyperspace, and therefore should be carefully considered.Main conclusionsBest practise for constructing n‐dimensional hypervolumes and assessing their similarity are drawn, representing a practical aid for scientists using the 'hypervolume' R package in their research. These recommendations apply to most datatypes and analytical scenarios. The R scripts published alongside this methodological study can be modified for performing large‐scale analyses of species niches or automatically assessing pairwise similarity metrics among multiple hypervolume objects.
