Published: May 2019

Introduction. The aim of the present study was to compare static and dynamic balance among professional athletes in football and basketball. Methods. In this cross-sectional study, 47 professional, male football and basketball players from Pro League in Iran participated. They were divided into 3 groups. Group 1 included 16 participants with history of grade 1 or 2 single ankle sprain within the past 6 months. Group 2 included 17 participants with recurrent ankle sprain. Group 3 included 14 participants without history of ankle sprain. Static and dynamic balance were measured by the Balance Error Scoring System (BESS) and modified Star Excursion Balance Test (SEBT), respectively. Results. For the single-leg stance on a firm surface, group 2 scored errors with a high mean value of 3.94 compared with the other 2 groups, and the difference was statistically significant (P = .03). Significant differences in BESS scores are observed on both surfaces across the tandem limb between groups 2 and 3. Conclusion. The measures from the SEBTs may not reflect the balance performance especially in well-trained athletes who have a better balance when performing sport-related skills. However, BESS includes static postures, and it may reflect postural deficits better than dynamic tests in the more experienced athlete.

Published: May 2019

Background:

The risk of chronic metformin pharmacotherapy to cause vitamin B12 deficiency and its associated medical complications has been of immense concern among diabetic patients. Some studies have postulated that vitamin B12 deficiency is highly prevalent among chronic metformin-treated adult diabetic patients.

Aim:

This study aimed to determine the prevalence of vitamin B12 deficiency among metformin-treated and metformin-naïve type 2 diabetes mellitus patients.

Materials and methods:

This was a case-control, prospective, analytical, observational study of 200 adult participants (100 per group) attending the Endocrinology, Medical Out-patients Clinic of Irrua Specialist Teaching Hospital, Irrua, Edo State, Nigeria. The participants’ serum vitamin B12 levels were determined using an immunoassay technique. Data were presented using tables and charts. Chi-square test was used to compare non-continuous proportional variables.

Results:

The prevalence of vitamin B12 deficiency was 41% and 20% among metformin-treated and metformin-naïve type 2 diabetes mellitus groups, respectively (p = 0.001). Borderline vitamin B12 status was present among 59% of metformin-treated group and 80% of metformin-naïve group (p = 0.001). Neither metformin-treated nor metformin-naïve groups had normal serum vitamin B12 levels.

Conclusion:

The prevalence of vitamin B12 deficiency was significantly high in diabetics, especially the metformin-treated patients. We advocate for vitamin B12 supplementation among this group of patients in order to prevent the occurrence of vitamin B12 deficiency complications such as macro-ovalocytic anemia, impaired immunity with hypersegmented neutrophils, peripheral neuropathy and subacute degeneration of the spinal cord.
Much ado about nothing: Zeros and the extreme right
Authors: Kates Sean
Published: May 2019

The literature surrounding extreme right parties in Europe has developed dramatically over the past two decades. However, the analysis of electoral success for these parties has produced muddled results, and occasionally even conflicting findings. This article argues this confusion is partially due to a reliance on an inappropriate model choice. Through the use of simulations, a goodness-of-fit exercise, and a prediction exercise based on model cross-validation, I show that the traditional Tobit specification—adopted to deal with electoral results of fringe parties—is theoretically untenable, statistically inferior to alternative models, and practically prone to revealing effects that are unsupported by the underlying data. Rather, the results suggest that best practices should see researchers adopt Cragg or Heckman models for two-stage questions, or consider adopting an analysis applying multiple overimputation if the main question is focused on the determinants of electoral success.

Surface modification of halloysite nanotubes grafted by dodecylamine and their application in reinforcing polytetrafluoroethylene
Authors: Cheng Zhi-Lin , Chang Xing-Yu , Liu Zan
Published: May 2019

The modification of halloysite nanotubes (HNTs) as fillers is very effective at improving the performance of polymers. A novel modification of HNTs through grafting dodecylamine onto their surfaces was conducted here. Owing to the improvement in dispersibility of HNTs in polytetrafluoroethylene (PTFE), the mechanical properties and wear resistance (in particular) of the dodecylamine-modified HNT-filled PTFE composite were enhanced significantly.

Background

HIV-infected individuals on antiretroviral therapy (ART) require treatment with artemisinin-based combination therapy (ACT) when infected with malaria. Artemether–lumefantrine (AL) is the most commonly used ACT for treatment of falciparum malaria in Africa but there is limited evidence on the safety and efficacy of AL in HIV-infected individuals on ART, among whom drug–drug interactions are expected. Day-42 adequate clinical and parasitological response (ACPR) and incidence of adverse events was assessed in HIV-infected individuals on efavirenz-based ART with uncomplicated falciparum malaria treated with AL.

Methods

A prospective, open label, non-randomized, interventional clinical trial was conducted at St Paul’s Hospital in northern Zambia, involving 152 patients aged 15–65 years with uncomplicated falciparum malaria, who were on efavirenz-based ART. They received a 3-day directly observed standard treatment of AL and were followed up until day 63. Day-42 polymerase chain reaction (PCR)-corrected ACPRs (95% confidence interval [CI]) were calculated for the intention-to-treat population.

Results

Enrolled patients had a baseline geometric mean (95% CI) parasite density of 1108 (841–1463) parasites/µL; 16.4% (25/152) of the participants had a recurrent malaria episode by day 42. However, PCR data was available for 17 out of the 25 patients who had malaria recurrence. Among all the 17 patients, PCR findings demonstrated malaria re-infection, making the PCR-adjusted day-42 ACPR 100% in the 144 patients who could be evaluated. Even when eight patients with missing PCR data were considered very conservatively as failures, the day-42 ACPR was over 94%. None of the participants, disease or treatment characteristics, including day-7 lumefantrine concentrations, predicted the risk of malaria recurrence by day 42. AL was well tolerated following administration. There were only two cases of grade 3 neutropaenia and one serious adverse event of lobar pneumonia, none of which was judged as probably related to intake of AL.

Conclusions

AL was well tolerated and efficacious in treating uncomplicated falciparum malaria in HIV co-infected adults on efavirenz-based ART. However, a higher than anticipated proportion of participants experienced malaria re-infection, which highlights the need for additional malaria prevention measures in this sub-population after treatment with AL.

Background

Lifestyle intervention may have a critical effect on the association between genetics and obesity. This study aimed to investigate changes inFTOandIRX3gene expression in obese and overweight male adolescents undergoing a lifestyle intervention and the role ofFTOgenotype in this interaction.

Methods

This study was a field trial of 62 adolescents from boys’ high schools in Tehran, Iran. Two schools were randomly allocated as the intervention (n = 30) and control (n = 32) schools. The rs9930506 SNP inFTOwas genotyped at baseline and the level ofFTOandIRX3expression in peripheral blood mononuclear cells (PBMCs). Anthropometric measurements were assessed at baseline and after 18 weeks of intensive lifestyle intervention.

Results

Our results showed thatIRX3expression in the intervention group was significantly up-regulated compared to baseline (P = 0.007) and compared to the control group (P = 0.011).The intervention group had significantly up-regulated transcripts ofIRX3only in rs9930506 risk allele carriers of the intervention group compared to risk allele carriers of the control group (P = 0.017). Moreover, our data showed that the FTO expression was up-regulated in AA genotype carriers and down-regulated in AG/GG genotype carriers (P = 0.017).

Conclusion

Lifestyle modification may exert its effects on obesity through changes in the expression level of theFTOandIRX3genes. However,FTOgenotype plays a role in the extent of the effect of lifestyle changes on gene expression. Further studies are crucial to have a better understanding of the interaction between lifestyle, genetics and anthropometric measurements.

Learning from Riyadh
Authors: Menoret Pascal
Published: May 2019

What can we learn from Riyadh? What does this massive desert capital teach us about cities that other, better-studied places don't? This article examines the making of one of the most salient characteristics of Riyadh: its carscape. In 2000, 93 percent of all daily trips in Riyadh were done by private car, 5 percent were done by taxi, and 2 percent were done by collective transit, which means that private or hired cars were used in 98 percent of all 5 million daily trips in the city. The city looks today like a geometric, far-flung suburb crisscrossed by large highways and spotted with bouquets of high rises. Instead of developing around one central core in a contiguous manner, Riyadh grew around the massive usage of cars. Why and how did the suburbanization of Riyadh happen? How did Saudi automobility become the overwhelming social and political structure it is now?
Protocol for a Japanese nationwide repeated cross-sectional study to assess tobacco and nicotine product use behaviour after market introduction of tobacco heating products (THPs)
Authors: Adamson Jason , Kanitscheider Claudia , Prasad Krishna , Camacho Oscar M. , Beyerlein Elisabeth , Keralapura Yoga , Proctor Christopher , Murphy James
Published: May 2019

Background - In recent years there has been a proliferation of alternative tobacco and nicotine products that reduce consumers’ exposure to harmful substances and therefore have the potential to reduce risk to health. Post-market surveillance enables the evaluation of newly introduced tobacco and nicotine products (aka potentially reduced risk products (PRRPs)) at a population level. This study aims to investigate tobacco and nicotine consumer demographics and discover how people are using these products, and characterise behavioral trends as transitions between tobacco heated products (THPs) and other nicotine products. These behavioural aspects, in conjunction with the intrinsic risk of the product, are essential for assessing the potential health effects and establishing a population risk assessment.

Design and methods - This epidemiological cross-sectional study will collect data using a self-administered study instrument from the general Japanese population aged 20 years and older. The targeted sampling size is up to 5,000 participants per study wave. The study addresses the following objectives: estimation of tobacco and nicotine use prevalence; characterisation of  product usage by product type; changes in use behaviour in general, with particular emphasis on the introduction of THPs in the time period of one year; risk perceptions of different tobacco products and no tobacco usage; and participant perceived health status and quality of life.

Discussion - The description of tobacco and nicotine product use behaviour, the estimation of prevalence data, the measuring of product-specific risk perception and the change of tobacco use behaviour within one year will allow for a comprehensive assessment of the effect of introducing THPs into a market. These data could also be used to inform a system dynamics population model in order to estimate the public health impact of introducing a THP into the Japanese market.
Bilateral Liability-Based Contracts in Information Security Outsourcing
Authors: Hui Kai-Lung , Ke Ping Fan , Yao Yuxi , Yue Wei T.
Published: May 2019

We study the efficiency of bilateral liability-based contracts in managed security services (MSSs). We model MSS as a collaborative service with the protection quality shaped by the contribution of both the service provider and the client. We adopt the negligence concept from the legal profession to design two novel contracts: threshold-based liability contract and variable liability contract. We find that they can achieve the first best outcome when postbreach effort verification is feasible. More importantly, they are more efficient than a multilateral contract when the MSS provider assumes limited liability. Our results show that bilateral liability-based contracts can work in the real world. Hence, more research is needed to explore their properties. We discuss the related implications.

Adopting Seekers’ Solution Exemplars in Crowdsourcing Ideation Contests: Antecedents and Consequences
Authors: Koh Tat Koon
Published: May 2019

Crowd-based ideation contests facilitate solution-seeking firms (seekers) to address their problems by soliciting ideas from external individuals (solvers). In this study, we examine how seekers’ involvement—particularly in terms of the exemplars and prizes that they provide—shape the ideation process and outcomes in such contests. Although seekers’ decisions about the exemplars to show and prizes to offer may be independent from one another, we show that certain aspects of these decisions jointly impact the extent to which solvers adopt seekers’ exemplars in their ideas. This finding demonstrates that individual facets of seeker involvement could intertwine and have intricate effects on solvers right from the initiation of the contests. We further show that, by influencing solvers’ exemplar adoption, seekers can also affect the effectiveness of the ideas. All in all, our results indicate that seekers acquire ideas not just through the crowd but also with the crowd, and they play an active role in how and what solvers ideate. Instead of simply delegating idea generation to solvers, seekers should thus share the onus of ideation and be aware of the impacts of their involvement in contests.
Motivating Effective Mobile App Adoptions: Evidence from a Large-Scale Randomized Field Experiment
Authors: Sun Tianshu , Shi Lanfei , Viswanathan Siva , Zheleva Elena
Published: May 2019

The adoption and usage of mobile devices have fundamentally altered users’ experience in a multichannel world. With the rise of mobile channels, firms have designed thousands of campaigns and spent billions of dollars to motivate or even subsidize app adoptions. However, it is not clear whether and how firms can effectively increase customers’ purchases through these induced adoptions. Using a randomized field experiment involving over 230,000 customers on a major daily deal platform, we investigate the differential impacts of offering incentives or information on customers’ app adoptions and subsequent purchase behaviors. We find that the causal effect of induced app adoptions varies greatly depending on how customers are motivated. Although providing incentive encourages most adoptions, incentive-induced adoptions do not result in more purchases in the long run. In contrast, providing information leads to effective mobile adoptions that sustainably increase customers’ purchases and overall profits for the firm. We further identify a complementary effect between mobile app and desktop channels for information-induced app adopters, because the app serves as a deal discovery tool for them. Finally, we find that information works as a sorting device and attracts customers who have a greater need for the app and use it more effectively.
Efficient Rare-Event Simulation for Multiple Jump Events in Regularly Varying Random Walks and Compound Poisson Processes
Authors: Chen Bohan , Blanchet Jose , Rhee Chang-Han , Zwart Bert
Published: May 2019

We propose a class of strongly efficient rare-event simulation estimators for random walks and compound Poisson processes with a regularly varying increment/jump-size distribution in a general large deviations regime. Our estimator is based on an importance sampling strategy that hinges on a recently established heavy-tailed sample-path large deviations result. The new estimators are straightforward to implement and can be used to systematically evaluate the probability of a wide range of rare events with bounded relative error. They are “universal” in the sense that a single importance sampling scheme applies to a very general class of rare events that arise in heavy-tailed systems. In particular, our estimators can deal with rare events that are caused by multiple big jumps (therefore, beyond the usual principle of a single big jump) as well as multidimensional processes such as the buffer content process of a queueing network. We illustrate the versatility of our approach with several applications that arise in the context of mathematical finance, actuarial science, and queueing theory.

Support for feminism among highly religious Muslim citizens in the Arab region
Authors: Glas Saskia , Spierings Niels
Published: May 2019

Public opinion studies argue that in Middle Eastern and North African countries, Muslims support gender equality less than non-Muslims. This overlooks the diversity in religion–feminism relations. Highly religious Muslims who support feminism are disregarded, even though in-depth studies have repeatedly pointed to their existence. Grounded in a structured anthology of qualitative studies on Muslim feminism, we provide the first ever large-scale analysis of support for Muslim feminism. Conducting latent class analyses on 64,000 Muslims in 51 Middle Eastern and North African contexts, we find that a substantial one in five Arab Muslims combines high attachment to Islam with support for feminism.

Comparison of conventional polymerase chain reaction and routine blood smear for the detection of Babesia canis, Hepatozoon canis, Ehrlichia canis, and Anaplasma platys in Buriram Province, Thailand
Authors: Rucksaken Rucksak , Maneeruttanarungroj Cherdsak , Maswanna Thanaporn , Sussadee Metita , Kanbutra Pithai
Published: May 2019

Background and Aim: Dog blood parasites are important tick-borne diseases causing morbidity and mortality in dogs worldwide. Four dog blood parasites species are commonly found in Thailand: Babesia canis, Hepatozoon canis, Ehrlichia canis, and Anaplasma platys. They are transmitted easily by tick species. However, there is little prevalence data available in Thailand. Diseases presentation of blood parasites infection is similar, but the treatment of each species is different. Current diagnosis mainly relies on microscopic examination of a stained blood smear, which has low sensitivity. Therefore, accurate diagnosis is important. This study aims to evaluate the efficacy of the conventional polymerase chain reaction (PCR) method and routine blood smears in the detection of four blood parasites species in dogs from Buriram Province, Thailand. Materials and Methods: In total, 49 EDTA-blood samples were collected from dogs in Buriram Province, Thailand. Blood parasite infection was compared using the Giemsa-stained blood smear technique to identify the parasite under a 100× oil immersion with PCR amplification of the 18S rDNA gene of B. canis and H. canis and the 16S rDNA gene of E. canis and A. platys. Results: Only one dog out of 49 was positive for H. canis based on microscopic examination whereas the PCR results showed that 2.04% (1/49), 4.08% (2/49), 36.73% (18/49), and 30.61% (15/49) of dogs were positive for B. canis, H. canis, E. canis, and A. platys, respectively. Moreover, coinfection was found in 16.33% (8/49) of dogs. Conclusion: This study is the first report to demonstrate the molecular prevalence of blood parasites in domestic dogs in Buriram Province. The results indicated that the PCR method exhibited much higher sensitivity and reliability for blood parasites diagnosis in dogs. Therefore, our data support serious concern regarding the diagnostic technique used in routine blood testing and also provide prevalence data for the management and control of blood parasites in this area.

The Limits of Dwelling and the Unwitnessed Death
Authors: Danely Jason
Published: May 2019

Demographic and policy changes in Japan during the first decades of the twenty-first century have resulted in significantly more people growing older and dying alone, especially in densely populated urban centers. As the national Long-Term Care Insurance system continues to promote community-based elder care despite weakened family and neighborhood bonds, the home has become an intensified space of care as well as a potential zone of abandonment. This article considers these divergent potentials of home and their implications for thinking about the material, ethical, and aesthetic limits of dwelling as embodied in the specter and spectacle of the lonely death (kodokushi). Such deaths and the empty houses they leave behind index other forms of loss emerging from intertwined histories of the family, welfare, and housing and construction policy. I argue that the connection between local experiences of aging and death and national policies can be found in mediating images and narratives of mourning, which seek to locate and make sense of the inability to dwell. Approaching unwitnessed deaths as specters at the limits of dwelling allows us to move beyond the shock of lonely death and draws our attention instead to the links between caring, mourning, and the home in an aged society.
要約
21世紀前半の20年間における日本の人口動態と政策の変化の結果、特に人口密集した都心部で、一人で老後を過ごし、亡くなっていく人々の数が著しく増大した。家族や近隣共同体の絆が弱まっているにもかかわらず、国の介護保険制度が地域を基盤とした在宅高齢者介護を促進し続けているため、居宅は介護の場となるだけでなく、潜在的な放棄の場ともなっている。この記事では、これらの居宅の多様な可能性を検討する中で、孤独死の幻影(spectacle)と光景(spectacle)が具現化した場としての住まい(dwelling)の物質的、倫理的、そして美的な限界について考察する。孤独死と残された空家は、家族や福祉、住宅、そして建設政策などが絡み合った歴史から生じる社会的な喪失を写し出すのだ。ここで議論されるのは、地域における高齢化および死の経験と国家政策との関係が、居住(dwell)不可能性を見定め、理解しようと努める哀悼のイメージや物語を仲介することで見出しうるということである。誰にも目撃されることのなかった死を、住まいの限界に現れた幻影としてアプローチすることで、孤独死のショックを乗り越え、高齢化社会における思いやりと、哀悼、そして居宅との関連性に注目することが可能となる。

Published: May 2019

W artykule zaprezentowano własne wyniki badań dotyczących postrzegania bezpieczeństwa przez radnych wybranych gmin i miast z województwa zachodniopomorskiego i lubuskiego. Zostały one przeprowadzone na przełomie 2015 i 2016 r. W badaniu wzięło udział 126 radnych – 78,26% spośród tych, którzy formalnie pracowali w badanych radach. Rezultaty badań porównano do wniosków z badania ogółu Polaków przeprowadzonego przez CBOS pod koniec 2014 r. Dokonana analiza pokazała, że radni oceniają poziom bezpieczeństwa i czynniki mu zagrażające nieco odmiennie. Radni wykazywali większe obawy dotyczące chaosu politycznego w Polsce, napływu uchodźców, a także ataków cybernetycznych oraz zagrożeń terrorystycznych. Wykazano również, że na poglądy radnych wpływ miały takie czynniki jak płeć, staż samorządowy oraz preferencje polityczne.
Strategie wyborcze Ryszarda Grobelnego i Jacka Jaśkowiaka w ponownym głosowaniu w świetle badań exit poll
Authors: Ossowski Szymon
Published: May 2019

Celem artykułu jest dokonanie analizy strategii wyborczych dwóch kandydatów na urząd prezydenta Poznania, którzy rywalizowali w ponownym głosowaniu podczas wyborów samorządowych w 2014 roku. Autor próbuje odpowiedzieć na pytania: czy Ryszard Grobelny mógł pomiędzy I i II turą odwrócić bieg wydarzeń i zwyciężyć ostatecznie w wyborach i jakie błędy popełnił w ostatnim okresie kampanii, że tak wyraźnie przegrał z Jackiem Jaśkowiakiem? Udzielając odpowiedzi na te pytania, sformułowano dwie hipotezy. Zgodnie z pierwszą, nie da się jednoznacznie stwierdzić, czy Ryszard Grobelny miał szansę na zwycięstwo po tak niskim wyniku w pierwszym głosowaniu, choć wiele wskazuje na to, że klucz do zwycięstwa znajdował się nie tyle w rękach Ryszarda Grobelnego, co w decyzjach innych kandydatów, którzy nie weszli do II tury. Druga hipoteza prowadzi to stwierdzenia, że największym błędem na finiszu kampanii był zwrot urzędującego prezydenta w kierunku elektoratu PiS i Tadeusza Dziuby. Weryfikacja tych hipotez, w szczególności drugiej została przeprowadzona na podstawie analizy badań exit poll, zrealizowanych w wieczór wyborczy podczas ponownego głosowania na urząd prezydenta Poznania przez Gemini na zlecenie Wielkopolskiej Telewizji Kablowej.

Published: May 2019

In this paper, we define a new class of posets which are complemented and ideal-distributive, we call these posets strong Boolean. This definition is a generalization of Boolean lattices on posets, and is different from Boolean posets. We give a topology on the set of all prime Frink ideals in order to obtain the Stone’s topological representation for strong Boolean posets. A discussion of a duality between the categories of strong Boolean posets and BP-spaces is also presented.

A conjecture for varieties of completely regular semigroups
Authors: Petrich Mario
Published: May 2019

The class 𝒞ℛ of completely regular semigroups considered with the unary operation of inversion within maximal subgroups forms a variety. The B-relation on the lattice ℒ(𝒞ℛ) of subvarieties of 𝒞ℛ identifies two varieties if they contain the same bands. Its classes are intervals with the set Δ of upper ends of these intervals. Canonical varieties form part of Δ. Previously we determined the sublattice Ψ of ℒ(𝒞ℛ) generated by the variety 𝒞𝒮 of completely simple semigroups and six canonical varieties.

The conjecture is that the sublattice of ℒ(𝒞ℛ) generated by 𝒞𝒮 and canonical varieties follows the pattern of the structure of Ψ.

The Menger and projective Menger properties of function spaces with the set-open topology
Authors: Osipov Alexander V.
Published: May 2019

For a Tychonoff space X and a family λ of subsets of X, we denote by C
λ(X) the space of all real-valued continuous functions on X with the set-open topology.

A Menger space is a topological space in which for every sequence of open covers 𝓤1, 𝓤2, … of the space there are finite sets 𝓕1 ⊂ 𝓤1, 𝓕2 ⊂ 𝓤2, … such that family 𝓕1 ∪ 𝓕2 ∪ … covers the space.

In this paper, we study the Menger and projective Menger properties of a Hausdorff space C
λ(X). Our main results state that

C
λ(X) is Menger if and only if C
λ(X) is σ-compact;

Cp
(Y | X) is projective Menger if and only if Cp
(Y | X) is σ-pseudocompact where Y is a dense subset of X.

In the present study, surface morphological differences of mixtures of triuranium octoxide (U3O8), synthesized from uranyl peroxide (UO4) and ammonium diuranate (ADU), were investigated. The purity of each sample was verified using powder X-ray diffractometry (p-XRD), and scanning electron microscopy (SEM) images were collected to identify unique morphological features. The U3O8 from ADU and UO4 was found to be unique. Qualitatively, both particles have similar features being primarily circular in shape. Using the morphological analysis of materials (MAMA) software, particle shape and size were quantified. UO4 was found to produce U3O8 particles three times the area of those produced from ADU. With the starting morphologies quantified, U3O8 samples from ADU and UO4 were physically mixed in known quantities. SEM images were collected of the mixed samples, and the MAMA software was used to quantify particle attributes. As U3O8 particles from ADU were unique from UO4, the composition of the mixtures could be quantified using SEM imaging coupled with particle analysis. This provides a novel means of quantifying processing histories of mixtures of uranium oxides. Machine learning was also used to help further quantify characteristics in the image database through direct classification and particle segmentation using deep learning techniques based on Convolutional Neural Networks (CNN). It demonstrates that these techniques can distinguish the mixtures with high accuracy as well as showing significant differences in morphology between the mixtures. Results from this study demonstrate the power of quantitative morphological analysis for determining the processing history of nuclear materials.

Type II toxin-antitoxin (TA) systems are the particular type of TA modules which take part in different kinds of cellular actions, such as biofilm formation, persistence, stress endurance, defense of the bacterial cell against multiple phage attacks, plasmid maintenance, and programmed cell death in favor of bacterial population. Although several bioinformatics and Pet lab studies have already been conducted to understand the functionality of already discovered TA systems, still, more work in this area is required. Rnl AB type II TA module, which is composed of RnlA toxin and RnlB antitoxin, is a newly discovered type II TA module which takes part in the defense mechanism against T4 bacteriophage attack in Escherichia coli K-12 strain MH1 that has not been widely studied in other bacteria. Because of the significant role of class Gammaproteobacteriacea in a diverse range of health problems, we chose here to focus on this class to survey the presence of the Rnl AB TA module. For better categorization and description of the distribution of this module in this class of bacteria, the corresponding phylogenetic trees are illustrated here. Neighbor-joining and the maximum parsimony methods were used in this study to take a look at the distribution of domains present in RnlA and RnlB proteins, among members of Gammaproteobacteria. Also, the possible roles of photodynamic therapy (PDT) in providing a substrate for better phage therapy are herein discussed.
The True Editor of the Manuductio ad linguam Tunkinensem (Seventeenth- to Eighteenth-Century Vietnamese Grammar)
Authors: Pham Ly Thi Kieu
Published: May 2019

The objective of this paper is to analyze the first two Vietnamese grammars written in Latin: (1) LinguaeAnnamiticae seu Tunchinensis Brevis Declaratio (1651), by Alexandre de Rhodes; and (2) Manuductio ad linguam Tunckinensem, a seventeenth- or eighteenth-century anonymous manuscript. Roland Jacques (2002) concluded that the editor of the Manuductio was Honufer Bürgin, and that Rhodes and Bürgin worked independently of each other starting with the same reference: the grammar of Francisco de Pina. This article also proposes a hypothesis about who the true editor of the Manuductio was.
Implicaciones éticas del capitalismo y la economía de mercado en la familia: relectura y tareas de la teología moral desde el Documento de Medellín
Authors: Agudelo Grajales Diego
Published: May 2019

This article, inspired by chapter III Family and Demography of the Document of Medellín (1968), warns in the introduction that it is the family who suffers most from the consequences of the "vicious circles" and the transformations that are generated in the economic order. Therefore, the approach is to treat from different levels of analysis the impact of capitalism and the market economy in this essential institution as is the family. Medellín is the inspirer, but the position of the Church will be critically reviewed through the social encyclicals recognizing its prophetic value of denunciation but also its silence, which has meant a legitimacy of this capitalist system.
“Siempre tienen a los pobres entre ustedes” (Jn 12, 8): la opción por los pobres: límites y desafíos para hoy
Authors: Caicedo Narváez Roberto
Published: May 2019

Regularly, the passage of John 12, 8 is used to justify the presence of the poor in the social context, as if it were a necessary condition, as something inevitable, natural and divine. The Medellín Conference brought forward in the theological and pastoral discussion the reality of poverty as an antievangelical situation. The implications of this challenge marked the impulse to accompany the demands of the social subjects in their aspirations for the political changes in Latin America that would end the conditions of economic and social marginalization, thus expanding the spectrum of their commitment. Today we find a continent that continues to look for ways out of these structural and cultural conditions that do not allow for the much desired change, because we still “have” the poor in our midst, and some do not resign ourselves to accept it as a divine or historical design. It is necessary a rereading that brings us closer to the biblical text with different eyes to better understand the challenge of Jesus today. These are the concerns that we intend to discuss in this paper, fifty years after the Medellin call to listen to the cry of the poor.
Fine-Scale Inference of Ancestry Segments Without Prior Knowledge of Admixing Groups
Authors: Salter-Townshend Michael , Myers Simon
Published: May 2019

Salter-Townshend and Myers present an open source tool for modelling multi-way admixture events using dense haplotype data. Their Hidden Markov Model approach is scalable to thousands of samples and, unlike existing methods...

We present an algorithm for inferring ancestry segments and characterizing admixture events, which involve an arbitrary number of genetically differentiated groups coming together. This allows inference of the demographic history of the species, properties of admixing groups, identification of signatures of natural selection, and may aid disease gene mapping. The algorithm employs nested hidden Markov models to obtain local ancestry estimation along the genome for each admixed individual. In a range of simulations, the accuracy of these estimates equals or exceeds leading existing methods. Moreover, and unlike these approaches, we do not require any prior knowledge of the relationship between subgroups of donor reference haplotypes and the unseen mixing ancestral populations. Our approach infers these in terms of conditional “copying probabilities.” In application to the Human Genome Diversity Project, we corroborate many previously inferred admixture events (e.g., an ancient admixture event in the Kalash). We further identify novel events such as complex four-way admixture in San-Khomani individuals, and show that Eastern European populations possess 1−3% ancestry from a group resembling modern-day central Asians. We also identify evidence of recent natural selection favoring sub-Saharan ancestry at the human leukocyte antigen (HLA) region, across North African individuals. We make available an R and C++ software library, which we term MOSAIC (which stands for MOSAIC Organizes Segments of Ancestry In Chromosomes).

RISK-ORIENTED APPROACH TO LABOR PROTECTION AT GRAIN PROCESS ENTERPRISES
Authors: FESENKO O. , LYSYUK V. , SAKHAROVA Z.
Published: May 2019

The article focuses on the introduction of a risk-oriented approach to labor protection at the enterprises of the grain processing industry. Such an approach is imperative in modern conditions in accordance with the Concept of reforming the system of labor protection management. This will involve the introduction of the proactive principle of “preventive actions” (prevention of hazardous events and situations) instead of the existing reactive principle of “corrective actions” (response to hazardous events and situations). A risk-oriented approach to occupational safety and health is the basis for the formation of a new national system for prevention of the operational risks. In the grain process enterprises, which have agreed their policy on labor protection with international standards, there has been an increase and improvement of the responsibility and competency of the ordinary employees and managers in the safety field, the risk of on-the-job injury has decreased. Improvement of the system of labor protection and risk management at enterprises should be carried out according to State Standard (DSTU) ISO 31000:2018 “Risk Management. Guidelines (ISO 31000:2018, IDT))”. The purpose of the standard is to reduce operational risks to an acceptable level. The main stages of the risk management process are presented. Identification of hazards, risk assessment, definition of security measures is a constituent and integral part of such a system. This is necessary to identify and understand the dangers that may arise in the course of an enterprise's activity, to assess the risk arising from a particular hazard, and to take measures to reduce the probability of occurrence of hazards. At the enterprises of the grain process industry, the identification of hazards consists in the definition of all objects, situations or actions (or their combination) that are inherent in an enterprise's activities and present a potential threat to the health and life of workers. At the same time, the different types of works and situations are considered in order to identify the dangers that are constantly present in normal working conditions, as well as the hazards, the impact of which is possible in case of deviation from normal working conditions and emergencies. Examples of possible hazardous factors at such enterprises are given. The adequacy of the existing security measures, the need for heir improvement or the introduction of other security measures are determined based on the results of the risk assessment.
