Learning behind glass walls: learning style and partition-room, is there a correlation?
Authors: Düştegör Dilek , Elhussein Mariam A. , Alghamdi Amani , Nagy Naya 
Published: May 2018

Purpose
This study aims to investigate how a very particular learning environment, namely, partition rooms, affect students’ teaching experience and further explore if students’ learning styles is a pertinent determinant. Partition rooms are very common in Saudi Arabia when lectures are held by male instructors for female students. The male instructor delivers his lesson behind a glass wall, creating an environment of limited visual and auditory interaction. Various digital tools are present, meant to overcome the gap caused by the lack of direct student–teacher contact.

Design/methodology/approach
The researchers collected data from a sample of 109 female students who are studying at Level 4 Computer Science Department, College of Computer Sciences and Information Technology, at a public university in Saudi Arabia. All of them experienced a minimum of two courses undertaken in a partition room. The survey consists of two parts with a total of 53 questions. The first 20 questions were adopted from the perceptual learning style preference questionnaire (PLSP).

Findings
Research findings reveal that students are affected differently by the various dimensions of the partition room depending on their learning style.

Originality/value
There are fewer results in the literature that study learners of our particular group, namely, Saudi females. The study focuses on students studying IT and related fields. This study is almost unique, as most studies of the kind are related to the experience of females learning English as a foreign language. Therefore, the authors’ research gives much-needed insight into the conditions and perceptions of female students studying toward their degree in a technical field.

PurposeThe management of materials consists of an important analysis for industries as there are factors in several areas that should be considered. For this, it should take into account logistical factors, quality and production, because one piece delivered in a large lead time or outside the technical quality standards, imply delays in the project or rework. In this context, the importance of creating a control method of input and output of tools in an aviation industry in the city of Toulouse, France, was seen due to the amount of many incomplete arrivals or inappropriate material for use. The paper aims to discuss this issue.Design/methodology/approachThis study used a philosophy of lean manufacturing tools and visual management (VM). A VM panel with information documents of all tools used in an assembly station of a model airplane was applied. With all data collected to carry out the project, the panel was created with the most relevant information of each tool and applied to an assembly station. That done, the production supervisors, mechanical and electrical supervisors were trained in the operation. Despite a change of management, it was realized that all supported the change due to the ease of understanding of the method and a good VM.FindingsAt the end of the work, materials management became more simplified, operators were more satisfied because of the non-occurrence of tools mistakes and the control time decreased from 120 to 15 minutes.Research limitations/implicationsThe application of this project has begun in an assembly station; however, it has been validated to be applied throughout the facility and its applications are being studied for other industries with different models.Practical implicationsThis project developed a visual panel for support visual communication of the airplane assembly line. Its usage eliminates tools lost, inefficiencies and decreases lost time with tools selection.Originality/valueThis work proposes a way to simplify the management tools for assembly station plane using a VM panel based on the lean philosophy. The study was conducted at the Final Assembly Line of an aircraft model from a unit of an aircraft company.

PurposeThe purpose of this paper is to offer insights into the processes associated with promoting volunteer engagement adopted by a large UK heritage attraction during a period of significant change. Engaged volunteers were regarded as essential to sustain, and where appropriate, to enhance the customer experience.Design/methodology/approachA case study approach was adopted. This involved review of relevant documentation and interviews and focus groups between researchers, managers and volunteers.FindingsWorking from the philosophical stance that information and involvement are strong predecessors to “buy-in”, the managers of the attraction used a series of initiatives that kept volunteers both informed and involved. These initiatives include a values-based induction programme, information and communication, training and development, and creating new narratives.Originality/valueVolunteer engagement influences volunteer commitment to the organisation. This case study offers some insights into initiatives adopted in one heritage organisation to promote volunteer engagement, and thereby provides a basis for other organisations to reflect on their practices in this area.

PurposeAs many organizations and institutions in recent years are trying to update their hardware and software platforms toward using mobile technology, libraries and information centers as trustees and leaders of information management and information science need to be futurists in this area. Therefore, the purpose of this paper is to investigate the status of using mobile-based services in the world’s top university libraries.Design/methodology/approachIn this direct observation and quantitative research survey, the authors reviewed the status of using mobile-based services in the libraries of the world’s top universities.FindingsThe results showed that 84 percent of the libraries of the top 50 universities in the world have made their websites mobile-friendly and provide mobile-based services; however, only 30 percent of them have designed mobile library application. The findings of this study revealed that mobile phone services such as “Search catalog,” “Hour of library,” “Contact,” “Ask the librarian” and “News” in more than 50 percent of the libraries with mobile-based services has been used. While some services like “Services for disabled,” “Library card,” “Library Strategic Plan” and “Financial services” are less important to deliver on the mobile platform.Research limitations/implicationsThe results of the current research are only limited to this environment. Furthermore limited access to all features of some mobile library applications is another limitation of this work. Also, failure to download some of the university apps from the usual App store due to the nationality of the researchers is other limitations of the study. The authors try to find more details of these apps with connecting to the librarians of this statistic society.Practical implicationsThe research results indicated that the majority of libraries in the world’s top universities have moved toward designing and using mobile platform in their websites. This survey suggests that the academic libraries of developing countries in order to follow this trend are supposed to plug in most used services based on experience of academic libraries of top universities.Originality/valueThe research results indicated that the majority of libraries in the world’s top universities have moved toward designing and using mobile platform in their websites. This survey suggests that the Iranian academic libraries affiliated with the Ministry of Science, Research and Technology and the Ministry of Health and Medical Education are also trying to follow this trend in order to meet the users’ information needs.
Research Note: First results of a low‐altitude unmanned aircraft system gamma survey by comparison with the terrestrial and aerial gamma survey data

Published: May 2018

ABSTRACTIn order to increase the efficiency of geological survey in difficult landscape‐morphological conditions, the authors have developed low‐altitude gamma technology surveys based on a multi‐rotor unmanned aircraft system, also known informally as Drones. These results have been compared against those from standard terrestrial and aerial gamma surveys. The successful results obtained at the reference site show that the developed methodology enables compilation of high‐quality data in difficult landscape conditions. These results yield the same level of information content as standard terrestrial gamma surveys. The exact unmanned aircraft system altitude over the earth must be maintained for carrying out high‐quality surveys. It was found that a CsI(Tl) detector with sizes 80 × 80 mm (vol. 0.4 dm3) enables obtaining of high‐quality radiometric data at altitudes of up to 70 m, at a speed of at least 20 km/h. The authors believe that low altitude ‘quasi‐terrestrial’ gamma surveys with a terrain drape may in the future replace terrestrial gamma surveys since they can offer better effectiveness at a lower cost.
Seed storage of Brazilian cacti species in different threat categories

Published: May 2018

AbstractCactaceae is considered the fifth most endangered taxonomic group. In light of this, the aim of this study was to evaluate the efficiency of different low‐temperature storage techniques in maintaining the viability of seeds of cacti in different threat categories. Seeds of six cacti taxa were stored in a cold chamber (8°C), a freezer (−5°C), in liquid nitrogen (−196°C) and at room temperature (25–27°C) for a period of 0, 1, 3, 6, 9 and 13 months. At each evaluation interval we removed a seed sample for each taxon studied, which was distributed into four repetitions of 25 seeds maintained at room temperature under 12‐h light/dark photoperiods. We evaluated the germinability, mean germination time and synchronization index. Most of the studied taxa presented germinability of above 50%, which was influenced by time and by storage temperatures. Also, most taxa stored at room temperature presented a significant reduction in germinability, whereas almost all taxa showed maintenance of the seed viability when stored in a cold chamber, a freezer or liquid nitrogen. This response can be justified by the reduction of the seed metabolism and the degradation of the reserve compounds of the seeds while at lower temperatures. Our results indicate that storage at low temperatures is an effective method for the conservation of cacti seeds and can be used for the formation of artificial seed banks of threatened cacti species.
HOW COLLECTIVE IS COLLECTIVE EFFICACY? THE IMPORTANCE OF CONSENSUS IN JUDGMENTS ABOUT COMMUNITY COHESION AND WILLINGNESS TO INTERVENE
Authors: BRUNTON‐SMITH IAN , STURGIS PATRICK , LECKIE GEORGE 
Published: May 2018

AbstractExisting studies have generally measured collective efficacy by combining survey respondents’ ratings of their local area into an overall summary for each neighborhood. Naturally, this approach results in a substantive focus on the variation in average levels of collective efficacy between neighborhoods. In this article, we focus on the variation in consensus of collective efficacy judgments. To account for differential consensus among neighborhoods, we use a mixed‐effects location‐scale model, with variability in the consensus of judgments treated as an additional neighborhood‐level random effect. Our results show that neighborhoods in London differ, not just in their average levels of collective efficacy but also in the extent to which residents agree with one another in their assessments. In accord with findings for U.S. cities, our results show that consensus in collective efficacy assessments is affected by the ethnic composition of neighborhoods. Additionally, we show that heterogeneity in collective efficacy assessments is consequential, with higher levels of criminal victimization, worry about crime, and risk avoidance behavior in areas where collective efficacy consensus is low.
Skin autofluorescence, a non‐invasive biomarker for advanced glycation end products, is not related to the number of pregnancies

Published: May 2018

Highlights

Skin autofluorescence (SAF) assesses subcutaneous accumulation of advanced glycation end products and has been shown to predict future cardiovascular disease and diabetes.
A higher number of pregnancies was significantly associated with higher SAF, even after correction for relevant confounders like waist circumference, creatinine clearance, and diabetes status, but not after correction for age.
Women with the highest SAF Z‐score had a more unfavorable risk factor profile, with higher body mass index and waist circumference, higher blood pressure, lower high‐density lipoprotein cholesterol, and higher triglyceride levels.

AbstractAimsTo estimate the impact of existing high‐coverage needle and syringe provision (HCNSP, defined as obtaining more than one sterile needle and syringe per injection reported) and opioid substitution therapy (OST) on hepatitis C virus (HCV) transmission among people who inject drugs (PWID) in three UK settings and to determine required scale‐up of interventions, including HCV treatment, needed to reach the World Health Organization (WHO) target of reducing HCV incidence by 90% by 2030.DesignHCV transmission modelling using UK empirical estimates for effect of OST and/or HCNSP on individual risk of HCV acquisition.Setting and participantsThree UK cities with varying chronic HCV prevalence (Bristol 45%, Dundee 26%, Walsall 19%), OST (72–81%) and HCNSP coverage (28–56%).MeasurementsRelative change in new HCV infections throughout 2016–30 if current interventions were stopped. Scale‐up of HCNSP, OST and HCV treatment required to achieve the WHO elimination target.FindingsRemoving HCNSP or OST would increase the number of new HCV infections throughout 2016 to 2030 by 23–64 and 92–483%, respectively. Conversely, scaling‐up these interventions to 80% coverage could achieve a 29 or 49% reduction in Bristol and Walsall, respectively, whereas Dundee may achieve a 90% decrease in incidence with current levels of intervention because of existing high levels of HCV treatment (47–58 treatments per 1000 PWID). If OST and HCNSP are scaled‐up, Walsall and Bristol can achieve the same impact by treating 14 or 40 per 1000 PWID annually, respectively (currently two and nine treatments per 1000 PWID), while 18 and 43 treatments per 1000 PWID would be required if OST and HCNSP are not scaled‐up.ConclusionsCurrent opioid substitution therapy and high‐coverage needle and syringe provision coverage is averting substantial hepatitis C transmission in the United Kingdom. Maintaining this coverage while getting current drug injectors onto treatment can reduce incidence by 90% by 2030.

Published: May 2018

SummaryVariations in ear size can be observed in livestock such as sheep; however, the genetic basis of variable ear size in sheep is still poorly understood. To investigate causative genes associated with ear size in sheep, a genome‐wide association study was performed in 115 adult Duolang sheep with different‐sized floppy ears using the Ovine Infinium HD BeadChip. We found 38 significant SNPs at the genome‐wide or chromosome‐wise 5% significance level after Bonferroni correction. The most significant association (P = 1.61 × 10−6) was found at SNP rs402740419, located in the DCC gene, which plays a critical role in ear development. Also, we observed two additional significant SNPs, rs407891215 in PTPRD and rs407769095 in SOX5, both of which are functionally associated with ear developmental processes. Our results are useful for future sheep breeding and provide insights into the genetic basis of ear size development in sheep and other livestock.

Published: May 2018

AbstractThe objective of this study was to evaluate a pulsatile extracorporeal membrane oxygenation (ECMO) system in terms of hemodynamic energy generation and transmission under various pulsatile amplitudes, flow rates, and pseudopatient pressures in a simulated adult ECMO circuit. Surplus hemodynamic energy (SHE), a measure of the quality of pulsatility, was used to quantify pulsatile flow. The circuit consisted of an i‐cor diagonal pump, an adult XLung oxygenator, a 21 Fr Medtronic Biomedicus femoral arterial cannula, a 23/25 Fr Sorin RAP femoral venous cannula, and 3/8 in ID tubing for both arterial and venous lines. The circuit was primed with lactated Ringer's solution and then packed red blood cells (hematocrit 37%). Trials were conducted at 36°C with flow rates of 2‐5 L/min (1 L/min increments) under nonpulsatile and pulsatile mode with pulsatile amplitudes of 1000–5000 rpm (1000 rpm increments). The pseudopatient pressure was maintained at 40–100 mm Hg (20 mm Hg increments). Real‐time pressure and flow data were recorded for analysis using a custom‐made data acquisition system. There was no SHE generated by the pump under nonpulsatile mode. Under pulsatile mode, SHE levels increased with increasing pulsatile amplitude and pseudopatient pressure (P < 0.01) but decreased with increasing flow rate. SHE levels were significantly higher at flow rates of 2–4 L/min. In addition, the XLung oxygenator had acceptable pressure drops (36.1–104.9 mm Hg) and percentages of total hemodynamic energy loss (19.6–43.9%) during all trials. The novel pulsatile ECMO system can create nonpulsatile and pulsatile flow in an adult ECMO model. However, pulsatility gradually weakened with increasing flow rates. Pulsatile amplitude settings were found to have a great impact on pulsatility.
Inhibition of protein arginine methyltransferase 3 activity selectively impairs liver X receptor‐driven transcription of hepatic lipogenic genes in vivo

Published: May 2018

AbstractBackground and PurposeAgonists for the liver X receptor (LXR) are considered promising therapeutic moieties in cholesterol‐driven diseases by promoting cellular cholesterol efflux pathways. However, current clinical application of these agents is hampered by concomitant LXR‐induced activation of a lipogenic transcriptional network, leading to hepatic steatosis. Recent studies have suggested that protein arginine methyltransferase 3 (PRMT3) may act as a selective co‐activator of LXR activity. Here, we verified the hypothesis that PRMT3 inhibition selectively disrupts the ability of LXR to stimulate lipogenesis while maintaining its capacity to modulate macrophage cholesterol homeostasis.Experimental ApproachA combination of the LXR agonist T0901317 and palm oil was administered to C57BL/6 mice to maximally stimulate LXR and PRMT3 activity. PRMT3 activity was inhibited using the allosteric inhibitor SGC707.Key ResultsTreatment with SGC707 did not negatively influence the T0901317/palm oil‐induced up‐regulation of the cholesterol efflux ATP‐binding cassette transporter genes, ABCA1 and ABCG1, in peritoneal cells. In contrast, SGC707 treatment was associated with a significant decrease in the hepatic expression of the lipogenic gene fatty acid synthase (−64%). A similar trend was observed for stearoyl‐coenzyme A desaturase and acetyl CoA carboxylase expression (−43%; −56%). This obstruction of lipogenic gene transcription coincided with a significant 2.3‐fold decrease in liver triglyceride content as compared with the T0901317 and palm oil‐treated control group.Conclusion and ImplicationsWe showed that inhibition of PRMT3 activity by SGC707 treatment selectively impairs LXR‐driven transcription of hepatic lipogenic genes, while the positive effect of LXR stimulation on macrophage cholesterol efflux pathways is maintained.

AbstractThe Valdivian rainforest, one of the global hotspots of biodiversity, is a temperate rainforest originating as a Tertiary relic from the supercontinent Gondwana. In November 2014, a survey of Phytophthora diversity was performed in 13 natural forest stands and 20 forest streams and rivers in two protected areas near Valdivia and in a temperate montane forest in the Concepción area. One planted stand each of the introduced tree species Castanea sativa and Fagus sylvatica were also included. Using baiting assays, eight described species and four previously unknown taxa of Phytophthora were isolated from 86% of the 50 rhizosphere soil samples from seven of the eight tree species sampled in 12 forest stands, and from 20 streams: P. chlamydospora, P. cinnamomi, P. kernoviae, P. lacustris, P. plurivora, P. pseudosyringae, P. ×cambivora, P. ×stagnum, P. valdiviana nom. prov. from Clade 2b, P. madida nom. prov. from Clade 8a, and P. chilensis nom. prov. and P. pseudokernoviae nom. prov. The latter two species are the closest relatives of P. kernoviae from Clade 10. Phytophthora pseudokernoviae nom. prov. was also isolated from necrotic leaves of Drimys winteri. From the Valdivia river, a swarm of three Clade 6 hybrids was recovered. Each hybrid isolate resulted from multiple reticulation events with P. thermophila as maternal and both P. amnicola and P. chlamydospora as paternal parents. In addition, three previously unknown and recently described Nothophytophthora species, N. caduca, N. chlamydospora and N. valdiviana, were isolated from several forest streams. Phytophthora cinnamomi, the most common and widespread species in soils of native forests, was associated with severe dieback of Valdivian rainforest trees, in particular D. winteri, Luma apiculata, Nothofagus dombeyi and the endangered Saxegothaea conspicua. A first pathogenicity test demonstrated high aggressiveness of P. cinnamomi to several native tree species, including N. dombeyi, Blepharocalyx cruckshanksii and Gevuina avellana.
