Authors: Morsli Souad , Boussoufi Mustapha , Sabeur Amina , El Ganaoui Mohammed , Bennacer Rachid 
Published: December 2017

Purpose
The use of natural ventilation by large openings to maintain thermal comfort conditions in the premises is a concept that is perfectly integrated into the traditional architecture of countries in the Mediterranean region or in tropical climates. In a temperate climate where the architecture is not usually designed to respond to the use of natural ventilation is seasonal and is done at the initiative of the occupants by making changes in the design of their doors. The European interest in natural ventilation, as a passive building air-conditioning technology, is increasing and has been the subject of a research program commissioned by the European Community. In this work, the authors consider a part of a housing compound as a refreshing floor. This floor is maintained at a constant cold temperature, the one vertical wall at hot temperature and other surfaces are adiabatic. Various scenarios are considered for this work. Mixed convection for different boundary conditions and different configurations is carried out. In addition, an airflow is injected through a window and extracted on the opposite window. Classical conclusion and transitional value on Richardson number have been completed by the new thermal configuration with nonsymmetric thermal conditions. The complex 3D flow structure is more obvious when one of the two flows (ventilation or natural convection) dominates. However, the induced heat transfer is less sensitive to the added ventilation. In this study, the authors consider a part of a housing compound as a refreshing floor. This floor is maintained at a constant cold temperature, the one vertical wall at hot temperature and other surfaces are adiabatic.

Design/methodology/approach
This is a qualitative preliminary study of a 2D–3D flow. The authors examine the competition between the natural convective flow and the added airflow on the flow structure and indoor air quality. The numerical model shows a good agreement with that obtained by researchers analytically and experimentally. To deal with turbulence, the RNG k-ε model has been adopted in this study.

Findings
The transfer is more sensitive between the 2D and 3D cases for the present analyzed case.

Originality/value
The study of ventilation efficiency has shown the competition between the big and small structures and the induced discomfort.
Towards ubiquitous human gestures recognition using wireless networks
Authors: Aljumaily Mustafa S. , Al-Suhail Ghaida A. 
Published: December 2017

Purpose
Recently, many researches have been devoted to studying the possibility of using wireless signals of the Wi-Fi networks in human-gesture recognition. They focus on classifying gestures despite who is performing them, and only a few of the previous work make use of the wireless channel state information in identifying humans. This paper aims to recognize different humans and their multiple gestures in an indoor environment.

Design/methodology/approach
The authors designed a gesture recognition system that consists of channel state information data collection, preprocessing, features extraction and classification to guess the human and the gesture in the vicinity of a Wi-Fi-enabled device with modified Wi-Fi-device driver to collect the channel state information, and process it in real time.

Findings
The proposed system proved to work well for different humans and different gestures with an accuracy that ranges from 87 per cent for multiple humans and multiple gestures to 98 per cent for individual humans’ gesture recognition.

Originality/value
This paper used new preprocessing and filtering techniques, proposed new features to be extracted from the data and new classification method that have not been used in this field before.

Authors: Kumar Sushil , Verma Anil Kumar 
Published: December 2017

Purpose
The purpose of this paper is to give an insight in to the routing protocols in Vehicular ad hoc Network (VANET). In this direction, for the efficient data dissemination in VANETs, a street-based forwarding protocol (SBFP) has been proposed.

Design/methodology/approach
The interferences among different street segments are considered and a unique street-based forwarding concept is introduced to reduce the local maximum problem. In this protocol, the greedy forwarding concept along with the broadcasting mechanism and suppression technique is implemented to minimize the overhead created in the regular beacons forwarding processes. QualNet simulator is used to implement and simulate SBFP. SUMO and MOVE tools are used to create the vehicle’s movement pattern and network topology.

Findings
The simulated results demonstrated improved packet delivery ratio (PDR) with a minimum average number of broadcast by each individual vehicle in the proposed SBFP than in its peer protocols.

Originality/value
This paper will be discussing a unique street-based forwarding technique exploring the advantages of global positioning system to obtain the location of vehicles and streets. This technique results in higher PDR and reduced network overhead.

SummaryRalstonia solanacearum thrives in plant xylem vessels and causes bacterial wilt disease despite the low nutrient content of xylem sap. We found that R. solanacearum manipulates its host to increase nutrients in tomato xylem sap, enabling it to grow better in sap from infected plants than in sap from healthy plants. Untargeted GC/MS metabolomics identified 22 metabolites enriched in R. solanacearum‐infected sap. Eight of these could serve as sole carbon or nitrogen sources for R. solanacearum. Putrescine, a polyamine that is not a sole carbon or nitrogen source for R. solanacearum, was enriched 76‐fold to 37 µM in R. solanacearum‐infected sap. R. solanacearum synthesized putrescine via a SpeC ornithine decarboxylase. A ΔspeC mutant required ≥ 15 µM exogenous putrescine to grow and could not grow alone in xylem even when plants were treated with putrescine. However, co‐inoculation with wildtype rescued ΔspeC growth, indicating R. solanacearum produced and exported putrescine to xylem sap. Intriguingly, treating plants with putrescine before inoculation accelerated wilt symptom development and R. solanacearum growth and systemic spread. Xylem putrescine concentration was unchanged in putrescine‐treated plants, so the exogenous putrescine likely accelerated disease indirectly by affecting host physiology. These results indicate that putrescine is a pathogen‐produced virulence metabolite.
Family Firm Configurations for High Performance: The Role of Entrepreneurship and Ambidexterity

Published: December 2017

AbstractThe performance drivers of family firms have spawned considerable research interest. Almost exclusively this research has relied on independent sets of explanatory variables in linear analyses. These analyses mask the complex interdependencies that are likely to exist among key success factors, leading to faulty theory and misspecified implications for practice. As treatment, the authors propose a configuration approach to family firm performance that accounts for complex interdependencies among entrepreneurial, innovation and family influence conditions. Using a fuzzy set qualitative comparative analysis of a sample of 129 Finnish family firms, the authors identify sufficient conditions with regard to the existence or absence of antecedent conditions to family firm performance. These conditions include entrepreneurial orientation, exploration and exploitation activities that form causal paths towards family firm performance. To enrich the analysis, the authors theorize and empirically analyse how these conditions might differ in family firms with high and low levels of family influence. They deepen the current understanding of configurations that promote the performance of family firms, offer important implications for theory and practice, and set new directions for future research on the strategic management of family firms. The results are also virtually identical and insensitive to change across subjective and objective performance measures.
Job Seekers with Musculoskeletal or Sensory Disabilities: Barriers and Facilitators of Job Search
Authors: Bainbridge Hugh T. J. , Fujimoto Yuka 
Published: December 2017

AbstractDrawing on interviews with job seekers and expert informants, we outline a model of the job search experience of people with disabilities. This model specifies the sequence of events involved in the pursuit of paid work and the contextual features that inhibit or facilitate job search attitudes, behaviours, intermediate search outcomes and employment outcomes. By contrasting the experiences of job seekers with musculoskeletal and sensory disabilities, and outlining the influence of major stakeholders in the form of employment agencies and family members, our model provides the basis for a more nuanced understanding of the job search process. Finally, we recommend points of intervention that are grounded in data for improving job search outcomes for people with disabilities in general, and for job seekers with musculoskeletal or sensory disabilities specifically.

AbstractBackgroundThis 24‐week Phase 3 double‐blind placebo‐controlled study assessed the safety and efficacy of dapagliflozin as add‐on to insulin, with or without oral antihyperglycemic drugs (OADs), in Asian patients with inadequately controlled type 2 diabetes mellitus.MethodsAdult patients with HbA1c between ≥7.5% and ≤10.5%, body mass index ≤45 kg/m2, and on insulin doses ≥20 IU daily were randomized to dapagliflozin 10 mg (n = 139) or placebo (n = 133) to assess 24‐week changes in HbA1c (primary outcome), fasting plasma glucose (FPG), body weight, total daily dose of insulin (TDDI), and seated systolic blood pressure (SeSBP; exploratory outcome).ResultsBaseline characteristics were similar in both groups. At Week 24, compared with placebo, dapagliflozin significantly improved HbA1c (mean [95% confidence interval] 0.03% [−0.11, 0.17] for placebo vs −0.87% [−1.00, −0.74] for dapagliflozin; between‐group difference − 0.90% [−1.09, −0.71], P < 0.0001]), FPG, body weight, TDDI, and SeSBP. The incidence of adverse events (AEs) in the dapagliflozin and placebo groups was 80.5% and 71.2%, respectively, with few patients discontinuing due to AEs (dapagliflozin, 2.2%; placebo, 4.2%). The occurrence of hypoglycemia was similar in the dapagliflozin and placebo groups (23.7% and 22.6%, respectively; no major events). The frequency of urinary tract and genital infections was low; no deaths were reported.ConclusionsDapagliflozin as add‐on to insulin, with or without OADs, significantly improved glycemic control and reduced body weight and blood pressure in Asian patients. Dapagliflozin was well tolerated, with a similar frequency of hypoglycemia in both groups. These results support the use of dapagliflozin as add‐on to insulin, with or without OADs, in this population.
Wallace: A flexible platform for reproducible modeling of species niches and distributions built for community expansion

Published: December 2017

Abstract

Scientific research increasingly calls for open‐source software that is flexible, interactive, and expandable, while providing methodological guidance and reproducibility. Currently, many analyses in ecology are implemented with “black box” graphical user interfaces (GUIs) that lack flexibility or command‐line interfaces that are infrequently used by non‐specialists.

To help remedy this situation in the context of species distribution modeling, we created Wallace, an open and modular application with a richly documented GUI with underlying R scripts that is flexible and highly interactive.

Wallace guides users from acquiring and processing data to building models and examining predictions. Additionally, it is designed to grow via community contributions of new modules to expand functionality. All results are downloadable, along with code to reproduce the analysis.

Wallace provides an example of an innovative platform to increase access to cutting‐edge methods and encourage plurality in science and collaboration in software development.

Published: December 2017

AbstractObjectivePrevious studies have shown a remarkable difference in functional health literacy among residents of urban and rural areas which may be attributed to socioeconomic inequalities between these areas. The aim of this study was to investigate the differences (if any) in the level of functional health literacy and its determinants between urban and rural areas in Sanandaj, Iran.DesignA descriptive analytical cross‐sectional study.ParticipantsA multistage clustered random sample of 1000 respondents older than 18 years. In total, 892 respondents (response rate = 89.2%) completed test of functional health literacy in adults questionnaire through personal home‐based interviews. Applying SPSS v. 16, a series of anova, t‐test and logistic regression tests were conducted.Main outcome measuresInadequate/marginal functional health literacy.ResultsRespondents residing in rural areas having a diploma education and lower, with no history of hospitalisation, with monthly income <US$ 165 and being diagnosed with a chronic disease had significantly higher rates of inadequate/marginal functional health literacy. Among rural, but not urban, residents having a history of hospitalisation, a university education and a higher monthly income increased the odds of adequate functional health literacy by 1.84, 2.29 and 1.95 times, respectively.ConclusionsThe rural area residents suffered more from low functional health literacy, compared with their urban counterparts. Health literacy as a determinant of health and social welfare should be focused on with more detail by health decision‐makers.
Congenital bilateral absence of the vas deferens as an atypical form of cystic fibrosis: reproductive implications and genetic counseling
Authors: de Souza D. A. S. , Faucz F. R. , Pereira‐Ferrari L. , Sotomaior V. S. , Raskin S. 
Published: December 2017

SummaryCongenital bilateral absence of the vas deferens (CBAVD) is found in 1% to 2% of males with infertility and is present in 6% of obstructive azoospermia cases. Nearly 95% of men with cystic fibrosis (CF, an autosomal recessive disorder) have CBAVD. There are genetic links between CBAVD and CF. Some mutations in the gene encoding cystic fibrosis transmembrane conductance regulator (CFTR) can lead to CBAVD as a monosymptomatic form of CF. With the use of assisted reproductive techniques (ART), especially testicular or epididymal sperm aspiration, intracytoplasmic sperm injection, and in vitro fertilization, it is possible that men with CBAVD can produce offspring. Therefore, genetic counseling should be offered to couples undergoing ART to discuss the probability of having offspring that carry CFTR gene mutations. The aim of this review was to present the main cause of CBAVD, to call attention to its implications for assisted reproduction, and to show the importance of genetic counseling for couples where men have CBAVD, as they can have offspring with a lethal disease.

Published: December 2017

AbstractAppendiceal intussusception is a rare disease in which the appendix invaginates into the cecum. It is often caused by organic diseases. The present case involved an appendiceal intussusception without an organic disease, and laparoscopic resection of part of the cecum was performed. Appendiceal intussusception has various causes, including malignant diseases. Therefore, diagnosis and selection of operative method are complex and could potentially lead to an excessively invasive option. By performing SILS with a multiuse single‐site port, we were able to provide an appropriate, non‐invasive treatment that had a good esthetic outcome.

SummaryIn the quantification and analysis of the distribution of soil basic components, factors such as spatial resolution, scales of observation and analytical techniques used to interpret digital images of microscopic platforms are critical to obtain reproducible results. In addition, individual or discrete images, sometimes with high spatial resolution, distort features or basic components when zooming in or out, which limits their classification. This research proposes the use of micromorphological tools, spatially referenced mosaics with high resolution, image analysis and composite images to elaborate thematic maps of soil components. Therefore, we created mosaics with sequential digital images from soil thin sections (up to 3850 mm2) of different diagnostic horizons, with different magnifications (2×, 10× and 20×) and light sources. The mosaics (between 0.25 and 2.6 μm2 per pixel, and between 2 and 8 GB file size) were processed by image analysis (segmentation, supervised classification and accuracy assessments) for delimiting their basic soil components from composite images and with spatial operators to elaborate thematic maps at the microscopic level. The RGB (red, green, blue) brightness values of each soil component with different light sources enabled us to identify and quantify size classes of aggregates, voids, pedofeatures and organic matter with different degrees of decomposition at a high level of precision (up to 99% overall accuracy). It was also possible to develop good‐quality thematic maps of such components from high‐resolution spatially referenced mosaics and composite images Thematic maps of soil components can be explored without losing their spatial reference and analysed on multiple scales from a whole soil thin section.Highlights
Micromorphology and digital cartography to develop thematic maps of soil components
High spatial resolution mosaics from thin sections and image analysis were used for mapping
RGB brightness values of different light sources facilitated mapping of soil features
Accurate maps enabled quantification and analysis of spatial relations of soil components

Published: December 2017

SummaryObjectiveTo characterize the evolution of behavioral and electrographic seizures in an experimental electrical stimulation‐based model of status epilepticus (SE) in C57Bl/6 mice, and to relate SE to various outcomes, including death and epileptogenesis.MethodsSE was induced by continuous hippocampal stimulation and was evaluated by review of electroencephalographic recordings, spectral display, and behavior.ResultsSeizures were initially locked to the electrical trains but later became independent of them. Following the end of stimulation, autonomous seizures continued for >5 minutes in 85% of the animals. There was ongoing 2‐3‐Hz rhythmic, high‐amplitude, slow spike‐wave discharges (HASDs) associated with purposeless, repetitive, continuously circling and exploratory behavior. There were high‐amplitude fast discharges (HAFDs) associated with worsening of behavioral seizures that were interspersed with the ongoing HASDs. Death during SE occurred in 23% of the animals, and it was preceded by a stage 5 behavioral seizure. In the waning stage of SE, severe seizures and HAFDs dissipated, HASDs slowed down, and normal behavior was restored in most animals. Epilepsy developed in 33% of the animals monitored after SE.SignificanceThe electrical stimulation model of SE can be used to study mechanisms of SE and its adverse consequences, including death and epileptogenesis.
