Published: August 2017

Background: Collaboration is a common occurrence among Vietnamese scientists; however, insights into Vietnamese scientific collaborations have been scarce. On the other hand, the application of social network analysis in studying science collaboration has gained much attention all over the world. The technique could be employed to explore Vietnam’s scientific community. Methods: This paper employs network theory to explore characteristics of a network of 412 Vietnamese social scientists whose papers can be found indexed in the Scopus database. Two basic network measures, density and clustering coefficient, were taken, and the entire network was studied in comparison with two of its largest components. Results: The networks connections are very sparse, with a density of only 0.47%, while the clustering coefficient is very high (58.64%). This suggests an inefficient dissemination of information, knowledge, and expertise in the network. Secondly, the disparity in levels of connection among individuals indicates that the network would easily fall apart if a few highly-connected nodes are removed. Finally, the two largest components of the network were found to differ from the entire networks in terms of measures and were both led by the most productive and well-connected researchers. Conclusions: High clustering and low density seems to be tied to inefficient dissemination of expertise among Vietnamese social scientists, and consequently low scientific output. Also low in robustness, the network shows the potential of an intellectual elite composed of well-connected, productive, and socially significant individuals.

Background.The intensification of insecticide use for both public health and agriculture in Africa has contributed to growing insecticide resistance. Today, resistance to World Health Organization (WHO)-approved insecticide classes is widespread. In an agricultural area of Southern Côte d’Ivoire, the main malaria vectorAnopheles coluzziishows multiple resistance across insecticides mediated by both target site mutation and metabolic mechanisms. To plan new vector control strategies and avert future resistance liabilities caused by cross-resistance mechanisms extant within populations, it is crucial to monitor the development and spread of both resistance and mechanisms.Methods. Larvae ofAnopheles gambiaewere collected from natural breeding sites in Tiassalé and Elibou, between April and November 2016 and raised to adults.Adult female non-blood fed mosquitoes, three to five days old, were exposed to deltamethrin in WHO bioassays. Extracted DNA samples from exposed mosquitoes were used for species characterisation and genotyping.Results.Most adultAn. gambiaetested were resistant to deltamethrin, with mortality rates of only 25% in Tiassalé and 4.4% in Elibou. Molecular analysis of DNA from samples tested showed the presence of bothAn. coluzziiandAn. gambiae s.sin Elibou and onlyAn. coluzziifor Tiassalé. As previously, the L1014Fkdrmutation was present at high frequency (79%) in Tiassalé and the L1014S mutation was absent. The N1575Y mutation, which amplifies resistance conferred by L1014F was detected in a single unique individual from a TiassaléAn. coluzziifemale whereas in Elibou 1575Y was present in 10An. gambiaes.s, but not inAn. coluzzii.Conclusion.This is the first report of the N1575Y mutation in Côte d’Ivoire, and as in other populations, it is found in both dominant West African malaria vector species. Continued monitoring of N1575Y is underway, as are studies to elucidate its contribution to the resistance of local vector populations.

Background: Inherited red blood cell disorders are prevalent in populations living in malaria endemic areas; G6PD deficiency is associated with oxidant-induced hemolysis and abnormal hemoglobin variants may cause chronic anemia. In pregnant women, microcytic anemia caused by hemoglobinopathies mimics iron deficiency, complicating diagnosis and treatment. Anemia during pregnancy is associated with morbidity and mortality. The aim of this study was to characterize the prevalence of G6PD deficiency, hemoglobinopathies, ABO and Rhesus blood groups among the pregnant population living along the Thailand-Myanmar border. Pregnant women attending antenatal clinics in this area belong to several distinct ethnic groups. Methods: Data was available for 13,520 women attending antenatal care between July 2012 and September 2016. Screening for G6PD deficiency was done by fluorescent spot test routinely. G6PD genotyping and quantitative phenotyping by spectrophotometry were analyzed in a subsample of women. Hemoglobin variants were diagnosed by HPLC or capillary electrophoresis and molecular methods. Blood groups were diagnosed by agglutination test. The prevalence and distribution of inherited red blood cell disorders and blood groups was analyzed with respect to ethnicity. Results: G6PD deficiency was common, especially in the Sgaw Karen ethnic group, in whom the G6PD Mahidol variant allele frequency was 20.7%. Quantitative G6PD phenotyping showed that 60.5% of heterozygote women have an intermediate enzymatic activity between 30% and 70% of the population median. HbE, beta-thalassemia trait and alpha-thalassemia trait were found in 31.2% of women. Only 0.15% of women were Rhesus negative. Conclusions: Distribution of G6PD and hemoglobin variants varied among the different ethnic groups, but the prevalence was generally high throughout the cohort. These findings encourage the implementation of an extended program of information and genetic counseling to women of reproductive age and will help inform future studies and current clinical management of anemia in the pregnant population in this region.
Do Plant Inspections Predict Future Quality? The Role of Investigator Experience
Authors: Ball George , Siemsen Enno , Shah Rachna 
Published: August 2017

Plant inspections enable firms to manage their quality risk in global supply chains. However, surprisingly little research examines the relationship between such inspections and future product quality. In this paper, we study how well plant inspection outcomes predict the hazard of a future recall and analyze how investigator experience affects this predictive relationship. Using secondary data spanning a seven-year period in the medical device industry and a recurrent-event Cox proportional hazard model, our analysis shows that inspection outcomes reliably predict future product recalls. However, inspection outcomes become an unreliable predictor of recalls with an increase in site-specific investigator experience. Through post hoc analysis, we also show that the hazard of a recall at a plant increases with site-specific experience, independent of the inspection outcome. Compared to the first visit by an investigator, the recall hazard increases by 21% the second time the investigator visits a specific plant, and by 57% on the third visit. We propose investigator rotation and investigator sequencing as two policies to help mitigate this increased recall risk. The online appendix is available at https://doi.org/10.1287/msom.2017.0661 .

Knowledge is the student’s construction result that affect to the more meaningful learning. Sometimes, teachers forget that a student has self-live experiences as their initial concept. When expressed their initial concept, students will be easier to accept new material knowledge, because students will constructing their knowledge indirectly. The constructivism of learning is a teaching and learning process to make students themselves mentally active to construct their knowledge, based on cognitive structure that they ever had before. In the relationship to the student’s geometry concept, it must be considered how the students constructing this concept by their cognitive structure. Memorizing the mathematical formulation is not the guarantee that the students have been mastering to the real geometry. For example, to understand about height line in the triangle, is not an instantaneous process. It can be learned by constructing through an experiment to involving all student hands on activity process. Through the activity to make a height line, measuring, and calculating the triangle area, student will be led on the joyful activity, avoid to the bored, toward the conclusion that every triangle, there are three height lines for the three triangle’s bases in each area.

Saham adalah salah satu sekuritas yang sering dipilih untuk melakukan investasi. Dalam investasi saham, seorang investor harus membuat portofolio optimal agar memperoleh hasil yang memuaskan (return tinggi atau risiko rendah). Salah satu metode untuk membentuk portofolio optimal adalah metode mean-varians yang diperkenalkan Markowitz, tapi metode ini mempunyai asumsi yang sering tidak terpenuhi dalam kenyataannya. Sehingga Markowitz memperkenalkan metode meansemivarians dari pendekatan risiko menurun. Dalam prakteknya, metode mean-varians lebih sering digunakan daripada metode mean-semivarians karena perhitungan mean-semivarians yang lebih sulit. Populasi pada penelitian ini adalah seluruh saham yang termasuk pada saham Jakarta Islamic Index (JII) periode Juni 2013 – Mei 2015. Indeks Sharpe portofolio metode mean-semivarians adalah 0,020098155.

Islam pernah mencapai masa keemasan dengan lahirnya tokoh-tokoh muslim yang tidak hanya menguasai fiqih dan tafsir, tetapi juga ahli dalam matematika dan astronomi. Pemikirannya sangat mempengaruhi perkembangan matematika di dunia. Namun kini dunia Islam mengalami kemunduran dengan semakin tersisihnya tokoh matematikawan muslim oleh matematikawan dari barat (Eropa). Oleh karenanya, penelitian ini bertujuan: (1) menelusuri penyebab kemajuan perkembangan matematika di negara-negara Islam pada abad pertengahan, (2) mengungkap penyebab munculnya gerakan renaissance di Eropa, dan (3) mengungkap hikmah yang dapat diambil terhadap pembelajaran matematika di sekolah. Penelitian ini merupakan penelitian kepustakaan (library research), dengan data yang didapatkan dari buku-buku bacaan ilmiah, jurnal ilmiah, laporan penelitian, situs internet dan lainya yang relevan dengan sejarah matematika abad pertengahan dan zaman Renaissance. Data yang telah terkumpul, selanjutnya dilakukan pemilahan dengan cara organize, synthesize dan identify. Hasil penelitian menunjukkan: (1) penyebab kemajuan perkembangan matematika di negara-negara Islam pada abad pertengahan yakni gencarnya kegiatan penerjemahan karya-karya matematika asing dan dukungan yang luar biasa para khalifah pada pengkajian matematika, (2) munculnya gerakan renaissance di Eropa sebagai wujud pemberontakan masyarakat Eropa atas doktrin gereja yang melarang perkembangan ilmu pengetahuan sehingga masyarakat Barat banyak yang lari ke negara Islam untuk menyerap karya matematikawan muslim dan membuat gerakan renaissance, dan (3) berdasarkan dua peristiwa penting bisa diambil hikmah terhadap pembelajaran matematika di sekolah. Khususnya bagi para peserta didik dalam belajar matematika dengan mengadopsi semangat keilmuwan dan menamkan sikap pantang menyerah dan percaya diri.

Growth induced buckling instability of anisotropic tube and its application in wound edge instability
Authors: Yang Le , Witten Tarynn M. , Pidaparti Ramana M. 
Published: August 2017

Abstract Fiber reinforced anisotropic material abounds in biological world. It has been demonstrated in previous theoretical and experimental works that growth of biological soft tubular tissue plays a significant role in morphogenesis and pathology. Here we investigate growth-induced buckling of anisotropic cylindrical tissue, focusing on the effects of type of growth(constraint/unconstraint, isotropic/anisotropic), fiber property(orientation, density and strength), geometry and any interaction between these factors. We studied one-layer and two-layer models and obtained a rich spectrum of results. For one-layer model, we demonstrate that circumferential fiber orientation has a consistent stabilizing effect under various scenarios of growth. Higher fiber density has a destabilizing effect by disabling high-mode buckling. For two-layer model, we found that critical buckling strain at inner boundary is an invariant under same isotropic growth rate ratio between inner/ outer layer(g1 /g0). Then we applied our model to wound healing and illustrate the effects of skin residual stress, fiber property, proliferation region width and wound size on the wound edge stability. We conclude that fiber-reinforcement is an important factor to consider when investigating growth induced instability of anisotropic soft tissue.
The indeterminacy of word segmentation and the nature of morphology and syntax
Authors: Martin Haspelmath 
Published: August 2017

AbstractThe general distinction between morphology and syntax is widely taken for granted, but it crucially depends on a cross-linguistically valid concept of ‘(morphosyntactic) word’. I show that there are no good criteria for defining such a concept. I examine ten criteria in some detail (potential pauses, free occurrence, mobility, uninterruptibility, non-selectivity, non-coordinatability, anaphoric islandhood, nonextractability, morphophonological idiosyncrasies, and deviations from bi-uniqueness), and I show that none of them is necessary and sufficient on its own, and no combination of them gives a definition of ‘word’ that accords with linguists’ orthographic practice. ‘Word’ can be defined as a language-specific concept, but this is not relevant to the general question pursued here. ‘Word’ can be defined as a fuzzy concept, but this is theoretically meaningful only if the continuum between affixes and words, or words and phrases, shows some clustering, for which there is no systematic evidence at present. Thus, I conclude that we do not currently have a good basis for dividing the domain of morphosyntax into morphology and syntax, and that linguists should be very careful with general claims that make crucial reference to a cross-linguistic ‘word’ notion.
The non-terracing tone system of Lolobi-Siwu
Authors: Ford Kevin C. , Iddah Robert K. 
Published: August 2017

Abstract
Siwu, a Ghana-Togo Mountain language spoken in Volta Region, Ghana, is a lexical tone language with three level tones, Low, High and Extra-high. Siwu has three distinct end-tones to mark positive-imperatives, non-WH-interrogatives, and negatives, and an additional end-tone to mark emphatic questions. All words form four tone classes – those with final Low tones which do not affect following tones, and three other classes, two of which assimilate following tones, and one which dissimilates following High and Extra-high tones. Two floating tones are posited: an Extra-high tone as an emp marker and a High tone as a poss marker to explain the changes affecting NP

Alles Inklusion, oder was?
Authors: Körner Swen 
Published: August 2017

Zusammenfassung
Der Inklusionsbegriff hat sich in den letzten Jahren gesellschaftlich etabliert. Inklusion tritt dabei vor allem auf als Forderung. Die Sportwissenschaft und hier insbesondere die Sportpädagogik haben den fordernden Inklusionsbegriff insgesamt eher ungebrochen übernommen. Inklusion versteht man hier vor allem als gesellschaftlichen Auftrag und ist mit dessen Umsetzung befasst. Lange vor dieser Konjunktur hat die soziologische Systemtheorie einen Inklusionsbegriff eingeführt, der dem normativen Verständnis diametral gegenübersteht. Verstanden als Relevanzmarkierung von Menschen für Kommunikation, ist Inklusion systemtheoretisch ein Faktum moderner Gesellschaften.
Im sportwissenschaftlich-sportpädagogischen Inklusionsdiskurs spielt die Systemtheorie der Inklusion bislang so gut wie keine Rolle. Der Beitrag setzt hier an. Ziel folgender Überlegungen ist es, dem gesellschaftlich und in der Sportwissenschaft vorherrschenden normativen Begriffsverständnis von Inklusion eine systemtheoretische Gebrauchsform gegenüber zu stellen. Für sportwissenschaftliche und sportpädagogische Inklusionsforschung bietet die Systemtheorie der Inklusion ein bislang kaum genutztes Analyse- und Reflexionspotenzial.

Abstract
Based on a fatigue testing machine common for metals, a new fatigue testing machine was developed to investigate the fatigue behavior of different rocks under completely reversed loading condition. The stress-life method was applied and the existence of the endurance limit was evaluated for three crystalline quarry stones from Iran, Natanz gabbro, Maroon marble, and Green onyx, which have different mineral compositions and grain distributions. The results indicate a similar linear trend in the variation of ultimate stress versus loading cycle number (S-N diagram) as well as the existence of the endurance limit as observed in ferrous metals. Moreover, the results illustrated that the endurance limits for all crystalline rocks of this study are obtained between 0.4 to 0.6 of their static tensile strengths. The higher fatigue resistance appeared in finer grained rocks.

NF-κB is a key player in inflammatory diseases, including multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). However, the effects of NF-κB activation on oligodendrocytes in MS and EAE remain unknown. We generated a mouse model that expresses IκBαΔN, a super-suppressor of NF-κB, specifically in oligodendrocytes and demonstrated that IκBαΔN expression had no effect on oligodendrocytes under normal conditions (both sexes). Interestingly, we showed that oligodendrocyte-specific expression of IκBαΔN blocked NF-κB activation in oligodendrocytes and resulted in exacerbated oligodendrocyte death and hypomyelination in young, developing mice that express IFN-γ ectopically in the CNS (both sexes). We also showed that NF-κB inactivation in oligodendrocytes aggravated IFN-γ-induced remyelinating oligodendrocyte death and remyelination failure in the cuprizone model (male mice). Moreover, we found that NF-κB inactivation in oligodendrocytes increased the susceptibility of mice to EAE (female mice). These findings imply the cytoprotective effects of NF-κB activation on oligodendrocytes in MS and EAE.SIGNIFICANCE STATEMENTMultiple sclerosis (MS) is an inflammatory demyelinating disease of the CNS. NF-κB is a major player in inflammatory diseases that acts by regulating inflammation and cell viability. Data indicate that NF-κB activation in inflammatory cells facilitates the development of MS. However, to date, attempts to understand the role of NF-κB activation in oligodendrocytes in MS have been unsuccessful. Herein, we generated a mouse model that allows for inactivation of NF-κB specifically in oligodendrocytes and then used this model to determine the precise role of NF-κB activation in oligodendrocytes in models of MS. The results presented in this study represent the first demonstration that NF-κB activation acts cell autonomously to protect oligodendrocytes against inflammation in animal models of MS.
