Inter-Personal and Inter-Organizational Networks In Internationalization of SMEs: A Bibliometric Analysis and Review
Authors: Bužavaitė Monika , Korsakienė Renata 
Published: September 2018

Abstract Small firms contribute to the economy by creating new vacancies and are the most common business form in the EU. However, small firms are not tended to expand internationally and only a limited number of small firms export to the countries outside the EU. The study aims to investigate inter-personal and inter-organizational networks in the international expansion of small firms. The investigation is grounded in analysis and synthesis of scientific literature. In addition, the bibliometric analysis was integrated into the scientific research. Bibliometric analysis of the papers published in 2000-2017 and obtained from Clari-vate Analytics database revealed that the significance of networking in international activities of small firms are not explored sufficiently while networking and internationalization of SMEs separately are a much more popular topic among researchers. The research results let us present insights for future investigations and implications for managers and policymakers.
Recent advances in the self-assembly of polynuclear metal–selenium and –tellurium compounds from 14–16 reagents
Authors: Polgar Alexander M. , Corrigan John F. 
Published: September 2018

AbstractThe use of reagents containing bonds between group 14 elements and Se or Te for the self-assembly of polynuclear metal–chalcogen compounds is covered. Background material is briefly reviewed and examples from the literature are highlighted from the period 2007–2017. Emphasis is placed on the different classes of 14–16 precursors and their application in the targeted synthesis of metal–chalcogen compounds. The unique properties arising from the combination of specific 14–16 precursors, metal atoms, and ancillary ligands are also described. Selected examples are chosen to underline the progress in (i) controlled synthesis of heterometallic (ternary) chalcogen clusters, (ii) chalcogen clusters with organic functionalized surfaces, and (iii) crystalline open-framework metal chalcogenides.

Published: September 2018

Abstract
Chylothorax is a rare condition characterized by accumulation of chylous fluid in the pleural space resulting in impaired ductus thoracic integrity. It can be an outcome of a traumatic process, although there are a few non-traumatic and/or idiopathic cases in current literature. In this article, we present the oldest case report so for, who is an 87-year-old woman complaining of acute respiratory distress symptoms with pleural effusion having no trauma history. The patient was analyzed for the disease etiology strenuously. Thoracentesis was performed together with imaging modalities and detailed systemic laboratory tests. Non-surgical treatment was successful as the outcome.

Abstract
Vehicles are being equipped with more and more smart devices, which help the driver in his tasks. Alongside the trend to more and more autonomous vehicles emerges the possibility of making vehicles that move together as a platoon, which can be defined as a spatio-temporal organization of a set of vehicles based on a specific predetermined geometrical configuration. Basically, there are two main approaches for performing platoon control and these depend on the reference frame used (local or global). Even if the literature about platoon control is abundant, the most commonly used metrics are only tied to the stability of the platoon, that is, to the lateral and longitudinal distances between vehicles. However, these metrics are sufficient enough for a first evaluation of one algorithm; a deeper evaluation of a platoon control solution requires more well-defined metrics and perturbations that allow for the testing of algorithms with various parametrized conditions. The goal of this article is to present definitions of metrics, perturbations, spatial configurations, and scenarios that are aimed at helping scientists in the field to determine strong and precise evaluations of their platoon control algorithms. The work presented in this article stems directly from thinking performed during the institutional projects in which the authors have been involved and also takes inspiration from numerous articles on the subject and experiments made both in simulation and with real vehicles.

Published: September 2018

Abstract
Aluminum metal matrix composites are attractive and effective materials because of their unique properties. These properties include high specific strength, light weight, high specific stiffness, excellent wear resistance, good corrosion resistance, and greater elastic modulus compared with the base alloy. They are used in aerospace, automotive, marine, mining, and mechanical structures. Fly ash, an inexpensive waste by-product obtained after the combustion of coal in thermal power plants, is considered as a reinforcement particle in the present study. The aim is to investigate the effect of fly ash in Al-10 weight percentage (wt%) aluminum oxide (Al2O3) metal matrix composites using statistical optimization techniques. One factor and Taguchi approaches are used in planning and designing the experiments. Al/10 wt% Al2O3 with 0, 5, 10, and 15 wt% fly ash composites are prepared with the powder metallurgy technique at 300, 400, and 500 MPa compaction pressure with 90, 120, and 150-μm fly ash particle sizes. The wt% of fly ash, compaction pressure, and particle size are the process parameters. Performance parameters such as ejection force and green density, hardness, and compressive strength are considered. The ejection force and green density decreased with the increase in the weight percent of fly ash. Hardness increased with the increase in fly ash content. Compressive strength increased with the increase in fly ash up to 5 wt% and subsequently decreased.
Predictors of Outcome in Cognitive and Behavioural Interventions for Irritable Bowel Syndrome. A Meta-Analysis
Authors: Radu Mădălina , Moldovan Ramona , Pintea Sebastian , Băban Adriana , Dumitrașcu Dan 
Published: September 2018

Background & Aims: Cognitive behavioural therapy (CBT) has small to medium effects in alleviating emotional distress and psychosomatic symptoms in irritable bowel syndrome (IBS). However, the mechanism through which CBT exerts its effects is less studied. Mediation analysis examines the extent to which intermediate variables explain the effect of the intervention on outcomes. The meta-analysis aims to identify and assess the impact of CBT mediators identified in previous research on IBS.
Methods: An extensive search of studies investigating the effects of CBT for IBS published before January 2018 was conducted. A total of 699 studies were identified through database search and 6 studies including data from 638 patients were analysed. The selected studies had to clearly define the CBT intervention, include IBS patients, report sufficient data to allow calculation of effect sizes and provide a clear mediation analysis of one or several variables on the outcome.
Results: The total effect of CBT was significant for both categories of outcomes (i.e. IBS symptom severity and psychosocial distress), with a low-to-moderate effect on psychosocial distress (r=0.222) and a medium-to-large effect on IBS symptom severity (r=0.413). In fact, the total effect of CBT on IBS symptom severity is significantly higher than the total effect on psychosocial distress Q(1)= 5.06, p= 0.024. Both behaviours and emotions (r=0.158) as well as cognitions (r=0.141) generated significant mediated effects on psychosocial distress, with no significant differences between them (Q(1)= 0.05, p=0.825). Behaviours and emotions mediated 71.1% of the total effect of CBT on psychosocial distress and cognitions mediated 63.5% of the total effect.
Conclusion: Although significant for both outcomes, the statistical analysis revealed CBT interventions have a greater effect on alleviating IBS symptoms severity rather than on reducing psychological distress. Of the mediators investigated, behaviours, emotions and cognitions seem to have a small to moderating effect in reducing IBS symptom and psychological distress.
Fecal Calprotectin in Assessing Inflammatory Bowel Disease Endoscopic Activity: a Diagnostic Accuracy Meta-analysis
Authors: Rokkas Theodore , Portincasa Piero , Koutroubakis Ioannis E 
Published: September 2018

Background & Aim: Fecal calprotectin (FC) has been suggested as a sensitive biomarker of inflammatory bowel disease (IBD). However, its usefulness in assessing IBD activity needs to be more precisely defined. In this meta-analysis we aimed to determine the diagnostic performance of FC in assessing IBD endoscopic activity in adults.
Methods: We searched the databases Pubmed/Medline and EMBASE, and studies which examined IBD endoscopic activity in association to FC were identified. From each study pooled data and consequently pooled sensitivity, specificity, likelihood ratios (LR), diagnostic odds ratios (DORs) and areas under the curve (AUCs) were calculated, using suitable meta-analysis software. We analyzed extracted data using fixed or random effects models, as appropriate, depending on the presence of significant heterogeneity.
Results: We included 49 sets of data from 25 eligible for meta-analysis studies, with 298 controls and 2,822 IBD patients. Fecal calprotectin in IBD (Crohn’s disease, CD and ulcerative colitis, UC) showed a pooled sensitivity of 85%, specificity of 75%, DOR of 16.3 and AUC of 0.88, in diagnosing active disease. The sub-group analysis revealed that FC performed better in UC than in CD (pooled sensitivity 87.3% vs 82.4%, specificity 77.1% vs 72.1% and AUC 0.91 vs 0.84). Examining the optimum FC cut-off levels, the best sensitivity (90.6%) was achieved at 50 μg/g, whereas the best specificity (78.2%) was found at levels >100 μg/g.
Conclusions: This meta-analysis showed that in adults, FC is a reliable laboratory test for assessing endoscopic activity in IBD. Its performance is better in UC than CD.
A Differential Host Response to Viral Infection Defines a Subset of Earlier-Onset Diverticulitis Patients

Published: September 2018

Background & Aims: Diverticulitis is the chronic inflammation of diverticula. Whether the pathophysiology of earlier-onset patients differs from later-onset patients is unknown. We profiled the colonic transcriptomes of these two patient populations to gain insight into the molecular underpinnings of diverticulitis.
Methods: We conducted deep RNA sequencing (RNA-seq) on colonic segments surgically resected from earlier-onset (<42 years old, n=13) and later-onset (>65 years old, n=13) diverticulitis patients. We used bioinformatic approaches to cluster the patients based on the relationship of differentially expressed genes and to inform on the molecular pathways that segregated the clusters.
Results: Principal component analysis identified three patient clusters; diverticulitis later-onset (DVT-LO), diverticulitis mixed-onset (DVT-MO), and diverticulitis earlier-onset (DVT-EO). The patients comprising DVT-EO, which was the majority of earlier-onset patients, displayed increased expression of anti-viral response genes. This finding was confirmed using an independent weighted co-expression network analysis (WGCNA) of differentially expressed genes.
Conclusions: We found that the majority of patients with earlier-onset disease contained elevated expression of host genes involved in the anti-viral response. Thus, susceptibility to a viral pathogen may offer one explanation why some individuals develop diverticulitis at an earlier age.

Published: September 2018

In this study, Cr3C2-25NiCr cermet coating samples were prepared by atmospheric plasma spraying (APS) technique on 410 stainless steel substrate with different plasma spraying parameters, namely, the plasma current (500 and 600 A), and the powder feed rate (10 and 30 g/min). The erosion-corrosion behaviour of the coatings was studied by electrochemical measurements, salt spray and erosion-corrosion tests. The electrochemical tests were performed in 3.5 wt.% NaCl solution. During the erosion-corrosion test, the samples were immersed in 3.5 wt.% NaCl solution containing 0.25 wt.% SiO2 particles with a rotational speed of 950 rpm for 72 hours. The obtained results showed that the plasma sprayed coating sample at the plasma current of 600 A and the powder feed rate of 10 g/min has a best erosion-corrosion resistance. Red rust spots did not appear on surface of this coating after 120 hours of salt spray test. It was much slower than on the others (after only 24 hours salt spray test). The weight loss of this coating during the erosion-corrosion test was lower than the remaining samples. These results are consistent with the results of electrochemical tests.

Authors: Phuong Phan Que 
Published: September 2018

In this study, we successfully synthesized Zn/Sn and Al/Sn catalysts by the combination of co-precipitation and hydrothermal methods.. These catalysts were prepared by hydrothermal method using zinc chloride ZnCl2, tin chloride SnCl4 and aluminium chloride AlCl3 precursors. Structure and physical properties of catalysts material were characterized by XRD, SEM. The products of glycerol conversion product was also tested by gas chromatography. The catalytic activity depends on reaction conditions (temperature and catalysts). The main product formed after the carbonylation reaction was glycerol carbonate. The selectivity of the main product was highest when using the Zn/Sn catalyst 5 % at a 145 °C during 5 hours with the yield was 77 %, the conversion degree was 88.5% and the selectivity was 86.91 %. For Al/Sn catalysts under the same reaction conditions, the efficiency was 61.3 % and the product selectivity achieved up to 74.05 % .

Published: September 2018

Background
Fibroblast growth factor 23 (FGF23), a bone-derived hormone that regulates phosphorus and vitamin D metabolism, contributes to the pathogenesis of mineral and bone disorders in CKD and is an emerging cardiovascular risk factor. Central elements of FGF23 regulation remain incompletely understood; genetic variation may help explain interindividual differences.

Methods
We performed a meta-analysis of genome-wide association studies of circulating FGF23 concentrations among 16,624 participants of European ancestry from seven cohort studies, excluding participants with eGFR<30 ml/min per 1.73 m2 to focus on FGF23 under normal conditions. We evaluated the association of single-nucleotide polymorphisms (SNPs) with natural log–transformed FGF23 concentration, adjusted for age, sex, study site, and principal components of ancestry. A second model additionally adjusted for BMI and eGFR.

Results
We discovered 154 SNPs from five independent regions associated with FGF23 concentration. The SNP with the strongest association, rs17216707 (P=3.0×10−24), lies upstream of CYP24A1, which encodes the primary catabolic enzyme for 1,25-dihydroxyvitamin D and 25-hydroxyvitamin D. Each additional copy of the T allele at this locus is associated with 5% higher FGF23 concentration. Another locus strongly associated with variations in FGF23 concentration is rs11741640, within RGS14 and upstream of SLC34A1 (a gene involved in renal phosphate transport). Additional adjustment for BMI and eGFR did not materially alter the magnitude of these associations. Another top locus (within ABO, the ABO blood group transferase gene) was no longer statistically significant at the genome-wide level.

Conclusions
Common genetic variants located near genes involved in vitamin D metabolism and renal phosphate transport are associated with differences in circulating FGF23 concentrations.

Published: September 2018

Background. The genus Hampea (Malvaceae: Gossypieae) has 21 reported species and occurs in Mexico, Central America and Colombia. Mexico has eleven species, of which seven are endemic. Hampea is of special conservation interest because its members are wild relatives of cultivated cotton and several species are apparently threatened by anthropogenic activities.Questions: What is the conservation status of species of Hampea in Mexico?Study site and years of study: Observations were made in the field during 1991-1995, 2012 and 2016 in southern Mexico. Specimen data was obtained from the CONABIO data base and from national and international herbaria from 2014-2016.Methods. The conservation status of species of Hampea in Mexico was evaluated using criteria given in the Methods of the Evaluation of Risk of Extinction of Plants (MER-Plantas) (NOM-059-SEMARNAT-2010). The potential distribution was calculated using Maximum Entropy Algorithm and biological data for species were obtained from literature and field observations.Results. Seven species of the genus Hampea were considered to be in a category of risk under the MER-Plantas criteria. Hampea montebellensis , H. breedlovei , and H. longipes were categorized as “at Risk of Extinction,” (En Peligro de Extinción ); H. latifolia was categorized as “Threatened” (Amenazada) and H. stipitata, H. mexicana, and H. tomentosa categorized as “Subject to Special Protection” ( Sujeto a Protección Especial ).Conclusions. The species H. breedlovei , H. montebellensis , H. longipes, H . latifolia, H. mexicana, H. stipitata and H. tomentosa need to be included in ex situ and in situ conservation programs.

Cancer Care: Impact of Interventions on Garegiver Outcomes
Authors: PASACRETA JEANNIE V. , MCCORKLE RUTH 
Published: September 2018

The purpose of this review is to examine the research literature on interventions aimed at caregivers who, in the current health care environment, are assuming increasing responsibility for the complex care of significant others experiencing cancer. The general aim of the review is to synthesize the literature on interventions targeted to cancer caregivers and to summarize outcomes associated with the various intervention strategies described. Three broad categories of interventions were described in the literature: (1) educational, (2) counseling/psychotherapeutic, and (3) hospice and palliative home care. The review included studies that met the following criteria; data-based studies that described an intervention aimed at assisting caregivers to care for patients with cancer, studies published between 1975 and January 1999, and studies published in English. A total of 29 published papers was included.Although the original intent was to limit the review to studies that associated interventions with outcomes, a lack of well-delineated outcome variables was revealed as a major gap in the literature. Thus, some studies that did not include outcome variables were reviewed and the following conclusions made: (1) there is a dearth of data-based literature describing interventions aimed at caregivers; interventions that are described often lack, well-defined effects due to a lack of or poor operationalization of outcomes; (2) of the small number of studies in this area, many used small samples and lacked randomization; and (3) studies often revealed selection bias to well-adjusted caregivers who were accepting of support, able to obtain respite care in order to participate, and often willing to avail themselves of a group-style intervention.
Alcohol Use, Misuse, Abuse, and Dependence in Later Adulthood
Authors: Stevenson Joanne S. 
Published: September 2018

Considerable research has focused on alcohol problems in older adults, but the clinical utilization of this knowledge has lagged at least 3 decades behind the scientific developments. This unfortunate situation takes on added significance as the “baby boomer” generation ages because more of them drink more often in larger quantities than previous generations. This chapter focuses more on the ramifications of use, misuse, and abuse than on chronic dependence because the prevalence in the former categories far outweighs the latter.Older alcohol misusers and abusers are at excess risk for myriad physical problems and premature death because alcohol interacts with the natural aging process in negative ways to increase risks for injuries, hypertension, cardiac dysrhythmic events, cancers, gastrointestinal problems, neurocognitive deficits, bone loss, and emotional challenges, most notably depression. Low volume and less than daily alcohol consumption appear to be protective against blood clots in the coronary and brain vessels, bone loss and falls, and cognitive decline compared with current abstainers. At higher levels, alcohol has the opposite effect.Research findings strongly support positive outcomes of case finding, referral, and treatment of older adults who are misusing or abusing alcohol. However, there is ample evidence that health care providers across the spectrum of primary, acute, and long-term care ignore the signs and symptoms of alcohol misuse and abuse in their older patients and treat symptoms and sequelae of the abuse rather than confronting the abuse itself. Recommendations for changes in practice are made together with ideas for additional research in several areas where the current state of knowledge is inadequate, conflicting, or based on narrowly homogeneous samples.
