Authors: Haley Jen , McCall Rebecca Carlson , Zomorodi Meg , De Saxe Zerdan Lisa , Moreton Beth , Richardson Lee
Published: July 2019

Background: The following case example provides an overview of one innovative way to engage health professions faculty with health sciences librarians in the development of an interprofessional book discussion and identifies strategies to address implementation challenges. Academic health sciences librarians worked with the Interprofessional Education (IPE) Steering Committee to organize interprofessional book discussion groups for incoming health professions students. This inaugural book discussion brought together students and faculty of different disciplines to engage students in “learning from, with, and about” other professions.Case Presentation: When Breath Becomes Air, by Paul Kalanithi, allowed involved discussions on important health sciences issues. The project included outreach, designing pre- and post-surveys, scheduling participants, and communicating with all participants before, during, and after the event. A total of seventy-nine students and thirty-six faculty, representing all health professions schools, participated in the small group IPE book discussions over two weeks.Conclusions: Small group book discussions have been shown to be an effective tool to engage students and faculty in IPE. The results of the participant surveys were positive, and the IPE Steering Committee found value in including health sciences librarians throughout the process. Lessons learned from the pilot project include needing an efficient scheduling system, strongly communicating at all stages of the project, and starting the planning process months ahead of time. The IPE Steering Committee plans to conduct similar book discussions every fall semester moving forward and explore options for other IPE events.
What is genomic medicine?
Authors: Roth Stephanie Clare
Published: July 2019

Genomic medicine is rapidly changing the future of medicine. Medical librarians need to understand this field of research and keep current with its latest advancements. Even if they are not directly involved in genomic medicine, librarians can play an integral role by helping health care consumers and practitioners who may also need to expand their knowledge in this area. This article provides a basic introduction to genomic medicine, gives a brief overview of its recent advancements, and briefly describes some of the ethical, legal, and social implications of this emerging area of research and practice.
Humor in library instruction: a narrative review with implications for the health sciences
Authors: Azadbakht Elena
Published: July 2019

Objective: The review sought to gain a better understanding of humor’s use and impact as a teaching and learning strategy in academic library and health sciences instruction and to determine if the most common techniques across both disciplines can be adapted to increase engagement in medical libraries’ information literacy efforts.Methods: This narrative review involved retrieving citations from several subject databases, including Library, Information Science & Technology Abstracts; Information Science & Technology Abstracts; Library & Information Science Source; PubMed; and CINAHL. The author limited her review to those publications that explicitly addressed the use of humor in relation to some form of academic library or health sciences instruction. Studies examining use of humor in patient education were excluded.Results: Scholars and practitioners have consistently written about humor as an instructional strategy from the 1980s onward, in both the library literature and health sciences literature. These authors have focused on instructors’ attitudes, benefits to students, anecdotes, and best practices summaries. Overall, both librarians and health sciences educators have a positive opinion of humor, and many instructors make use of it in their classrooms, though caution and careful planning is advised.Conclusions: Commonalities between the library and information science literature and health sciences literature provide a cohesive set of best practices and strategies for successfully incorporating comedy into library instruction sessions. Health sciences librarians can adapt several of the most commonly used types of instructional humor (e.g., silly examples, cartoons, storytelling, etc.) to their own contexts with minimal risk.
Professional development in evidence-based practice: course survey results to inform administrative decision making
Authors: Lauseng Deborah L. , Howard Carmen , Johnson Emily M.
Published: July 2019

Objective: To understand librarians’ evidence-based practice (EBP) professional development needs and assist library administrators with professional development decisions in their own institutions, the study team surveyed past participants of an EBP online course. This study aimed to (1) understand what course content participants found valuable, (2) discover how participants applied their course learning to their work, and (3) identify which aspects of EBP would be beneficial for future continuing education.Methods: The study team distributed an eighteen-question survey to past participants of the course (2011–2017). The survey covered nontraditional demographic information, course evaluations, course content applications to participants’ work, additional EBP training, and EBP topics for future CE opportunities. The study team analyzed the results using descriptive statistics.Results: Twenty-nine percent of course participants, representing different library environments, responded to the survey. Eighty-five percent of respondents indicated that they had prior EBP training. The most valuable topics were searching the literature (62%) and developing a problem, intervention, comparison, outcome (PICO) question (59%). Critical appraisal was highly rated for further professional development. Fifty-three percent indicated change in their work efforts after participating in the course. Ninety-seven percent noted interest in further EBP continuing education.Conclusions: Survey respondents found value in both familiar and unfamiliar EBP topics, which supported the idea of using professional development for learning new concepts and reinforcing existing knowledge and skills. When given the opportunity to engage in these activities, librarians can experience new or expanded EBP work roles and responsibilities. Additionally, the results provide library administrators insights into the benefit of EBP professional development.
Measuring impostor phenomenon among health sciences librarians
Authors: Barr-Walker Jill , Bass Michelle B. , Werner Debra A. , Kellermeyer Liz
Published: July 2019

Objective: Impostor phenomenon, also known as impostor syndrome, is the inability to internalize accomplishments while experiencing the fear of being exposed as a fraud. Previous work has examined impostor phenomenon among academic college and research librarians, but health sciences librarians, who are often asked to be experts in medical subject areas with minimal training or education in these areas, have not yet been studied. The aim of this study was to measure impostor phenomenon among health sciences librarians.Methods: A survey of 2,125 eligible Medical Library Association (MLA) members was taken from October to December 2017. The online survey featuring the Harvey Impostor Phenomenon scale, a validated measure of impostor phenomenon, was administered, and one-way analysis of variance (ANOVA) was used to examine relationships between impostor phenomenon scores and demographic variables.Results: A total of 703 participants completed the survey (33% response rate), and 14.5% of participants scored ≥42 on the Harvey scale, indicating possible impostor feelings. Gender, race, and library setting showed no associations, but having an educational background in the health sciences was associated with lower impostor scores. Age and years of experience were inversely correlated with impostor phenomenon, with younger and newer librarians demonstrating higher scores.Conclusions: One out of seven health sciences librarians in this study experienced impostor phenomenon, similar to previous findings for academic librarians. Librarians, managers, and MLA can work to recognize and address this issue by raising awareness, using early prevention methods, and supporting librarians who are younger and/or new to the profession. This article has been approved for the Medical Library Association’s Independent Reading Program.
Involvement of information professionals in patient- and family-centered care initiatives: a scoping review
Authors: DeRosa Antonio P. , Baltich Nelson Becky , Delgado Diana , Mages Keith C. , Martin Lily , Stribling Judy C.
Published: July 2019

Objective: The goal of this scoping review was to collect data on patient- and family-centered care (PFCC) programs and initiatives that have included the direct involvement of librarians and information professionals to determine how librarians are involved in PFCC and highlight opportunities for librarians to support PFCC programs.Methods: Systematic literature searches were conducted in seven scholarly databases in the information, medical, and social sciences. Studies were included if they (1) described initiatives presented explicitly as PFCC programs and (2) involved an information professional or librarian in the PFCC initiative or program. Based on the definition of PFCC provided by the Institute for Patient- and Family-Centered Care, the authors developed a custom code sheet to organize data elements into PFCC categories or initiatives and outcomes. Other extracted data elements included how the information professional became involved in the program and a narrative description of the initiatives or programs.Results: All included studies (n=12) identified patient education or information-sharing as an integral component of their PFCC initiatives. Librarians were noted to contribute to shared decision-making through direct patient consultation, provision of health literacy education, and information delivery to both provider and patient with the goal of fostering collaborative communication.Conclusions: The synthesis of available evidence to date suggests that librarians and information professionals should focus on patient education and information-sharing to support both patients or caregivers and clinical staff. The burgeoning efforts in participatory care and inclusion of patients in the decision-making process pose a unique opportunity for librarians and information professionals to offer more personalized information services.

This would work perfectly if it weren’t for all the humans: Two factor authentication in late modern societies
Authors: Watters Paul , Scolyer-Gray Patrick , Kayes A.S.M. , Chowdhury Mohammad Jabed Morshed
Published: July 2019

Late modern societies are now dependent on innumerable digitally networked technologies, yet there are intractable incongruencies between the technologies that we develop, and the corresponding technological literacies of users. This disjuncture has greatly increased the scope and scale of the risks to which globalized publics are exposed. With public cybersecurity literacies necessarily in decline as a result of the techno-social dynamism of “liquid modernity”, we now face an immense and exponentially growing matrix of cyberthreats and vulnerabilities, of which many carry potentially catastrophic consequences. Our interrogation of two-factor authentication systems, popularly implemented through short messaging services (SMSs), is demonstrative of vulnerabilities that continue to emerge as a result of widespread and entrenched disjunctures between the design of contemporary ICT systems, and the various flawed assumptions that undergird their implementation. We examined 400 authentication messages that were automatically posted to a public forum by Web sites commonly used to receive SMS authentication tokens on behalf of users. We found that 76.5 percent of those messages included the name of the application for which the message was intended: in so doing, over three quarters of our sample risked compromising their accounts. Occasionally, we even observed usernames and passwords posted together. The socio-technical implications of our findings for ICT system design in today’s globalized late modern societies are discussed.
Managing conflict in online debate communities
Authors: Beck Jordan , Neupane Bikalpa , Carroll John M.
Published: July 2019

Kialo is a novel peer production system focused on pro/con debate construction. Distributed moderator teams vet and accept claims submitted by writers. Moderators also edit and refactor debates as they grow. Thus, moderators play a critical role in cultivating and maintaining debates. Conflict between moderators is typical. It is a feature of argumentation and debate. However, not all conflict is productive. Conflict between moderators can undermine collaboration (by distracting from the task of managing debates) and drive attrition (by discouraging participation on the site altogether). Based on a ten-month participant observation on Kialo, we identify a common source of conflict between moderators: adversarial beliefs and values. Moderators are not neutral participants on Kialo. They take positions on debate topics. We suggest foregrounding these positions, which are potential sources of conflict, through interface design as a scalable way to facilitate conflict management.
The politics of user-platform relationships: Co-scripting live-streaming on Twitch.tv
Authors: Ask Kristine , Spilker Hendrik Storstein , Hansen Martin
Published: July 2019

What characterises the relationship between users and platforms? How are use and users configured by platform design, and in turn, how do users accept or reject such efforts? Using the live-streaming platform Twitch, this paper explores the user-platform relationship to answer these questions. Twitch is a highly popular live-streaming platform with an emphasis on gaming, whose rise to fame has been far from streamlined or expected. Based on qualitative analysis of design, discourse and user practices, the paper draws on script theory from science and technology studies and platform theory from Internet studies, to unpack the configuration of use and users. By tracing the development of the platform, we identify a pattern of frequent interaction between platform owners and users, and consequent course changes, which we label co-scription. Finally, we analyse the current Twitch script and propose five dimensions of co-scription that determine the user-platform relationship: 1) Sociality: community or individual use; 2) Audience: specific or general; 3) Moderation: strictly moderated or laissez-faire; 4) Content: user-generated or commercial; and 5) Scope: specialised or multi-feature.

Authors: Çoban Ercan , Kamış Ömer
Published: July 2019

This study aimed to determine the affective and socioeconomic variables significantly predicting achievement level of low- and high-achieving students. The data of 1323 low-achieving and 2022 high-achieving Turkish students participated in the PISA 2015 were used in the study. The data were analyzed by using binary logistic regression. The findings showed that test anxiety; achievement motivation; enjoyment of cooperation; environmental awareness; environmental optimism; science self-efficacy; epistemological beliefs; economic, cultural and social status index (ESCS), and the information and communication technology (ICT) resources index were significant predictors of the achievement level of low- and high-achieving students. While test anxiety and environmental optimism scores of low- achieving students were higher, achievement motivation, enjoyment of cooperation, environmental awareness, science self-efficacy, epistemological beliefs, ESCS, and ICT resources scores were higher among high-achieving students.

Published: July 2019

To accurately and efficiently remove unripe fruit, flowers, leaves, and other impurities in machine-harvested Lycium barbarum L., winnowing equipment for machine-harvested L. barbarum based on the principle that different materials have different flight coefficients was designed. To optimize the structure and working parameters of winnowing equipment, this study adopted the free flow resistance model to establish a horizontal airflow model based on C++ in Microsoft Visual Studio. A discrete element method (DEM) simulation of ripe fruit in the horizontal airflow was performed using EDEM software. Results showed that the optimal parameters included an airflow speed of 5-6 m/s, input conveyor speed of 0.4-0.6 m/s, and input-output conveyor distance of 260-270 mm. We used three factors and three levels in a quadratic orthogonal rotation design to establish mathematical models regarding the rate of impurity change and the clearance rate of ripe fruit based on the airflow speed, input conveyor speed, and input-output conveyor distance. We also analyzed the effects of all factors on the rate of impurity change and the clearance rate of ripe fruit. The optimal parameter combination was an airflow speed of 5.52 m/s, input conveyor speed of 0.5 m/s, and input-output conveyor distance of 265.04 mm. The field experiment showed that the rate of impurity change and the clearance rate of ripe fruit were 89.74% and 8.71%, respectively. Findings provide a design basis for future research on winnowing equipment for machine-harvested L. barbarum.

Authors: Ramos Carlos Henrique Oliveira , Araújo Fernanda Alves , Andrade Paulo César de Resende
Published: July 2019

A estatística experimental utiliza procedimentos de comparações múltiplas (PCM) a fim de verificar se há diferença entre os tratamentos em análise. Entretanto, a presença de dados desbalanceados e casos de heterogeneidade de variâncias influencia negativamente o desempenho dos testes mais utilizados. Os testes dbayes e pbayes foram implementados anteriormente no contexto dos delineamentos inteiramente casualizados por um dos autores. Esses testes são válidos para casos em que as pressuposições da análise de variância são atendidas ou não, com ou sem balanceamento. O presente artigo tem por objetivo realizar uma otimização da função Bayes, em código R, que permite a realização destes testes. Para validar a otimização, comparou-se o código otimizado com o código anterior e utilizou três situações reais: uma atendendo a todas as pressuposições, as outras duas com dados desbalanceados e com número diferente de tratamentos. A função Bayes otimizada propicia que os testes dbayes e pbayes tenham bons resultados em condições de atendimento das pressuposições e balanceamento. Estes testes podem ser utilizados satisfatoriamente nas situações de não atendimento das pressuposições. Nos casos de dados desbalanceados, com um pequeno número de tratamentos, o teste dbayes apresenta resultado superior ao teste de Tukey-Kramer.

Analysis of Suitable Farm Size for Fattening Pon Yang Kham Cattle
Authors: Wiwatthanapornchai Sitthinan
Published: July 2019

Pon Yang Kham Livestock Cooperative Limited (PYK Coop) is a local business organisation located in Sakon Nakhon province, Thailand. It has an essential economic role in assisting farmers and the community by creating a fair income distribution. However, PYK Coop has been facing problems from an oversupply of fattening cattle and the numbers involved in cattle production. This research investigated the costs and returns of production and the suitable farm size for beef cattle production to supply PYK Coop. The primary data were collected from 409 farmers in the cooperative using a questionnaire. The costs and returns of production were analysed and classified by the size of the farm to determine the most appropriate farm size for investment.

The results revealed that the average number of cattle for individual farmers was 10.10 consisting of 3.50 bulls and cows, 2.64 calves and growing cattle, and 3.50 feedlot cattle. The cost of cattle production was divided into variable and fixed costs, which ranged annually between THB 17,279.13 and THB 300,185.88. The total annual income was THB 274,836.43. The annual net return of production (total revenue minus cost) was THB 25,984.81, while the annual net return of production per head of cattle was THB 25,984.81. The optimal farm size for beef cattle for the cooperative was a medium-sized farm.

Overall, the results suggested that PYK Coop should encourage farmers to raise fattening cattle as a part-time occupation and aim to have no more than 10 head of cattle per farm. In doing so, PYK Coop should adjust the slaughter quota in accord with the number of beef cattle supplied by the farmers and should increase distribution channels to accommodate future production potential.
Epichloë (formerly Neotyphodium) fungal endophytes increase adaptation of cool-season perennial grasses to environmental stresses
Authors: Malinowski Dariusz Piotr , Belesky David Paul
Published: July 2019

Many cool-season grass species have evolved with asexual, nonsymptomatic fungal endophytes of the genus Epichloë (formerly Neotyphodium) of the family Clavicipitaceae. These associations range from parasitic to mutualistic and have dramatic effects on grass host chemistry, increasing resistance to abiotic (drought, soil mineral imbalance) and biotic (vertebrate and invertebrate herbivory, nematodes, plant pathogens, plant competition) stresses. Native endophyte strains produce a range of bioprotective alkaloid and other nonalkaloid secondary compounds, several of them known to have detrimental effects on grazing animals. In the past two decades, epichloid endophyte strains have been selected with marginal or no capacity of producing ergot and/or lolitrem alkaloids. These novel endophyte strains have been introduced to several grass cultivars with the idea to increase grass host resistance to abiotic stresses without hindering grazing livestock, and abiotic stresses to ensure high competitive ability of symbiotic grass cultivars. In this presentation, we discuss mechanisms underlying the competitiveness of epichloid endophyte/grass associations and consequences of endophyte infection for grassland ecosystem functions.
Photosynthetic performance of young maize (Zea mays L.) plants exposed to chilling stress can be improved by the application of protein hydrolysates
Authors: Cholakova-Bimbalova Rositsa , Petrov Veselin , Vassilev Andon
Published: July 2019

Biostimulants offer a novel approach for the regulation of crucial physiological processes in plants. Recently, it has been observed that the application of biostimulants on both seeds and plants may ameliorate to some extent the negative effects of abiotic stresses such as drought, heat, salinity, and others. In the climate conditions of Bulgaria, the early developmental stages of warm climate crops, like maize, often occur under suboptimal temperatures. Although the mitigation of abiotic stress is perhaps the most frequently cited benefit of biostimulant formulations, little is known about their influence on chilling-stressed plants. The aim of our study was to evaluate the effects of a biostimulant from the group of protein hydrolysates on both the growth and the photosynthetic performance of chilling-exposed young maize plants grown in controlled environment. Here, we report that application of a protein hydrolysate increased the performance of chilled maize plants, as demonstrated by leaf gas exchange, photosynthetic pigment content, and chlorophyll fluorescence, but did not affect their growth. Nevertheless, based on the better preserved photosynthetic performance of the biostimulant-treated maize plants exposed to chilling, we assume that under subsequent favorable conditions their growth would recover more quickly as compared to the untreated ones.
Rooting and growth of root cuttings of two old rose cultivars ‘Harison’s Yellow’ and ‘Poppius’ treated with IBA and biostimulants
Authors: Monder Marta Joanna
Published: July 2019

Propagation by root cuttings is an easy and low-cost method for plant taxa with an ability to produce rhizomes or suckers. This research examined the possibility of using root/rhizome cuttings in the propagation of two difficult-to-root old rose cultivars, ‘Harison’s Yellow’ and ‘Poppius’. A plant-based preparation (Root Juice), titanium (Tytanit), and IBA (Chryzotop Green 0.25% IBA, Rhizopon AA 020 XX 2.00% IBA) were tested as rooting and growth enhancers for thick, medium, and thin rhizome/root cuttings. Additionally, observations were made to identify the site of the initial root and shoot formation. Shoots appeared before roots, without polarity. The visible swellings differentiating in new root/shoot buds in these two rose cultivars were placed along the rhizome. The primordia of root and shoot buds were situated near the pith rays and the vascular cambial zone. The trial reported here showed significant effects of the thickness of root cuttings and the preparations used in terms of rooting success and growth characteristics. Medium-sized cuttings of rose ‘Harison’s Yellow’ (45.0%), and thin cuttings of ‘Poppius’ (74.3%) achieved the highest rooting percentages. The most effective treatment was with Chryzotop Green, but Root Juice 0.01% and Tytanit 0.04% (‘Poppius’) and 0.02% (both cultivars) also had positive activity. Root Juice and Tytanit can be suggested for rooting cuttings of these roses as eco-friendly preparations.

Genome-wide scans for detecting the selection signature of the Jeju-island native pig in Korea
Authors: Lee Young-Sup , Shin Donghyun , Won Kyeong-Hye , Kim Dae Cheol , Lee Sang Chul , Song Ki-Duk
Published: July 2019

Objective: The Jeju native pig (JNP) found on the Jeju Island of Korea is a unique black pig known for high-quality meat. To investigate the genetic uniqueness of JNP, we analyzed the selection signature of the JNP in comparison to commercial pigs such as Berkshire and Yorkshire pigs.Methods: We surveyed the genetic diversity to identify the genetic stability of the JNP, using the linkage disequilibrium method. A selective sweep of the JNP was performed to identify the selection signatures. To do so, the population differentiation measure, Weir-Cockerham’s Fst was utilized. This statistic directly measures the population differentiation at the variant level. Additionally, we investigated the gene ontologies (GOs) and genetic features.Results: Compared to the Berkshire and Yorkshire pigs, the JNP had lower genetic diversity in terms of linkage disequilibrium decays. We summarized the selection signatures of the JNP as GO. In the JNP and Berkshire pigs, the most enriched GO terms were epithelium development and neuron-related. Considering the JNP and Yorkshire pigs, cellular response to oxygen-containing compound and generation of neurons were the most enriched GO.Conclusion: The selection signatures of the JNP were identified through the population differentiation statistic. The genes with possible selection signatures are expected to play a role in JNP’s unique pork quality.

Objective: The aim of this study is to investigate the effect of oral spray with probiotics on the intestinal development and microflora colonization of hatched ducklings.Methods: In Exp. 1, an one-way factorial design was used to study the antibacterial activity of the probiotics and metabolites on Escherichia coli (E. coli) without antimicrobial resistance. There were four experimental groups including saline as control and Lactobacillus, Bacillus subtilis, combined Lactobacillus and Bacillus subtilis groups. In Exp. 2, 64-day-old ducklings were allotted to 2 treatments with 4 replicated pens. Birds in the control group were fed a basal diet supplemented with Lactobacillus fermentation in the feed whereas birds in the oral spray group were fed the basal diet and administrated Lactobacillus fermentation by oral spray way during the first week.Results: In Exp. 1, the antibacterial activities of probiotics and metabolites on E. coli were determined by the diameter of inhibition zone in order: Lactobacillus>combined Lactobacillusand Bacillus subtilis>Bacillus subtilis. Additionally, compared to E. coli without resistance, E. coli with resistance showed a smaller diameter of inhibition zones. In Exp. 2, compared to control feeding group, oral spray group increased (p<0.05) the final body weight at d 21 and average daily gain for d 1-21 and the absolute weight of the jejunum, ileum and total intestine tract as well as cecum Lactobacillus amount at d 21.Conclusion: Lactobacillus exhibited a lower antibacterial activity on E. coli with resistance than E. coli without resistance. Oral spray with Lactobacillus fermentation during the first week of could improve the intestinal development, morphological structure, and microbial balance to promote growth performance of ducklings from hatch to 21 d of age.
Expression characterization and transcription regulation analysis of porcine Yip1 domain family member 3 gene
Authors: Ni Dongjiao , Huang Xiang , Wang Zhibo , Deng Lin , Zeng Li , Zhang Yiwei , Lu Dongdong , Zou Xinhua
Published: July 2019

Objective: The Yip1 domain family (YIPF) proteins were proposed to function in endoplasmic reticulum (ER) to Golgi transport and maintenance of the morphology of the Golgi, which were homologues of yeast Yip1p and Yif1p. YIPF3, the member 3 of YIPF family was a homolog of Yif1p. The aim of present study was to investigate the expression and regulation mechanism of porcine YIPF3.Methods: Quantitative realtime polymerase chain reaction (qPCR) was used to analyze porcine YIPF3 mRNA expression pattern in different tissues and pig kidney epithelial (PK15) cells stimulated by polyinosine-polycytidylic acid (poly [I:C]). Site-directed mutations combined with dual luciferase reporter assays and electrophoretic mobility shift assay (EMSA) were employed to reveal transcription regulation mechanism of porcine YIPF3.Results: Results showed that the mRNA of porcine YIPF3 (pYIPF3) was widely expressed with the highest levels in lymph and lung followed by spleen and liver, while weak in heart and skeletal muscle. Subcellular localization results indicated that it expressed in Golgi apparatus and plasma membranes. Upon stimulation with poly (I:C), the level of this gene was dramatically up-regulated in a time- and concentration-dependent manner. pYIPF3 core promoter region harbored three cis-acting elements which were bound by ETS proto-oncogene 2 (ETS2), zinc finger and BTB domain containing 4 (ZBTB4), and zinc finger and BTB domain containing 14 (ZBTB14), respectively. In which, ETS2 and ZBTB4 both promoted pYIPF3 transcription activity while ZBTB14 inhibited it, and these three transcription factors all played important regulation roles in tumorigenesis and apoptosis.Conclusion: The pYIPF3 mRNA expression was regulated by ETS2, ZBTB4, and ZBTB14, and its higher expression in immune organs might contribute to enhancing ER to Golgi transport of proteins, thus adapting to the immune response.

Published: July 2019

One of the most hazardous thermodynamic phenomena occurring in mine headings is fires. One of the substances commonly present in those headings is methane – an easily combustible, odourless gas of natural origin. ethane is released into the mining atmosphere as a result of coal mining activities. Appropriate concentration levels of this gas and the presence of oxygen produce a mixture which can lead to methane combustion and explosion when in contact with an ignition source, such a spark. Both of these phenomena are extremely dangerous, especially in mine headings.

The article presents the results of a numerical analysis concerning methane ignition, leading to an exogenous fire in a mine heading. The purpose of the analysis was to demonstrate the mechanism of occurrence and development of methane fires, as well as to determine their consequences. This is because such fires cause emission of harmful and poisonous gases with extremely high temperatures into the mining atmosphere.

The model-bases tests of a methane fire were conducted using the “Partially Premixed combustion” (CFD) model. The analysis conducted helped to determine the distributions of speed, pressure and temperature of the air stream flowing through the region under analysis, as well as to specify the distributions of concentration levels for the combustion products (CO and CO2).

The article also describes the aerodynamics of the combustion process, as well as the phases of emergence, development and disappearance of fires. The model developed and the boundary conditions adopted for the tests reflect the real-world mine heading. The test method prepared for methane fires and the results obtained may represent a significant source of information for the mine’s ventilation service teams.
Ethnische Diskriminierung durch Bundestagsabgeordnete. Ein Feldexperiment

Diskriminierung aufgrund ethnischer Zugehörigkeit ist zwar mit rechtlichen und sozialen Normen unvereinbar, wird jedoch vielfach empirisch beobachtet. Die vorliegende Studie geht der Frage nach, ob ethnische Diskriminierung Bestandteil des sozialen Miteinanders in einem Kernbereich der Gesellschaft, der Politik, ist. Der Beitrag untersucht ethnische Diskriminierung in der Interaktion zwischen gewählten politischen Repräsentanten*innen, denen gemeinhin ein moralischer Vorbildcharakter zugeschrieben wird, und ihren Wählern*innen. Zudem möchten wir wissen, ob sich das Ausmaß ethnischer Diskriminierung zwischen Vertretern*innen unterschiedlicher Parteien unterscheidet. Dazu haben wir ein Korrespondenztest-Feldexperiment zur Hilfsbereitschaft von Abgeordnetenbüros des Deutschen Bundestags im Vorfeld der Bundestagswahl 2013 durchgeführt. An alle Bundestagsabgeordneten wurden Hilfeersuchen per E-Mail gerichtet, die randomisiert entweder mit einem deutsch oder türkisch klingenden Namen unterzeichnet waren. Unsere Ergebnisse zeigen, dass E-Mails mit türkisch klingenden Namen weniger häufig Antworten erhielten. Das ist ein Indiz für ethnische Diskriminierung. Zudem zeigen wir, dass sich das Diskriminierungsverhalten zwischen den Büros der Abgeordneten der im Bundestag vertretenen Parteien unterscheidet. Wir finden eine schwach ausgeprägte Diskriminierungsneigung bei Abgeordnetenbüros der Fraktion CDU/CSU, hingegen keine Anzeichen für Diskriminierung bei Abgeordnetenbüros von SPD, FDP, B90/Die Grünen und Die Linke. Nach Kontrolle des Lebensalters der Abgeordneten, der Bevölkerungsdichte des Wahlkreises, des Ausländeranteils in der Wahlkreisbevölkerung und, ob es sich um einen ost- oder westdeutschen Wahlkreis handelt, zeigen sich in den Modellen jedoch keine signifikanten Unterschiede zwischen den Fraktionen mehr.
Perspectives sur l’indépendance de la justice arbitrale en Afrique subsaharienne. Les influences croisées entre la Cour Commune de Justice et d’Arbitrage (CCJA) et l’East African Community’s Court of Justice (EACJ).
Authors: Bahalaokwibuye Christian Bahati
Published: July 2019

Le présent article pose les perspectives sur les influences opportunes et mutuelles des systèmes arbitraux de la CCJA et l’EACJ dans la promotion de l’indépendance des arbitres. İl montre que, tout comme pour l’EAC, l’abitrage figure déjà dans le Traité de l’OHADA comme le mode de règlement des différends en vue d’améliorer le climat des investissements sur les territoires des Etats parties. La CCJA n’est pas un tribunal arb itral. Son intervention est placée en aval, comme juge de contrôle de la sentence bien qu’elle ne se contente pas d’un contrôle minimal. L’EACJ, qui a retenu l’option du cumul des fonctions de ses juges avec celles d’arbtres, pourra aussi, dans la moindre mesure, se contenter d’administrer les arbitrages ouverts conformément à son Règlement d’arbitrage. De ce point de vue, le système EACJ sera en parfait accord avec l’esprit du principe d’indépendance/ impartialité. En cette matière, nous pensons que la pratique de la CCJA ne manquera pas d’inspirer utilement des réformes du système d’arbitrage de l’EACJ, et qui révèle de plus en plus une prise de conscience certaine d'une croissante indépendance de ses arbitres en ayant opté pour la gratuité de l’arbitrage. Comme le Centre d’arbitrage de la CCJA est attaché à la Cour et que cette dernière est dotée d’une autonomie financière, il est temps de prendre des mesures de réduction de coût, non pas totalement analogues à celles de l’EACJ, à travers lesquelles on dispensera, par exemple les ressortissants de l’espace OHADA et les investisseurs étrangers, des frais administratifs de l’arbitrage. Il en résulterait un arbitrage sans influences, alternative crédible à la justice étatique qui affiche la lanterne rouge et facile d’accès aux justiciables impécunieux, qui rendra des sentences impartiales et légitimes.
Civil Judge in Uganda: Remuneration Systems and Promotion Possibilities. How to Reward Efficient and Independent Decisions
Authors: Jackline-Bainipai Asiimwe
Published: July 2019

This piece of work is discusses the systems of remuneration of judges and promotion possibilities as well as rewarding efficient and independent decisions in Uganda. The research finds that whereas these three form part and parcel of the core of an independent judiciary, and whereas there are adequate legal provisions, the enforceability is lacking due to the fact that there are high levels of interference by the executive in the function of the judiciary. The remuneration, reward of an efficient judge are largely dependent on paying allegiance to the executive and deciding cases in appeasement of the executive. Yet, the remuneration, promotion and reward are supposed to be on merit. They should also be established by law and not subject to arbitrary interference from the executive. This study has revealed how the executive has substantial impact on remuneration, promotion and reward of efficient judges. Judges that decide cases according to the law irrespective of the interests of the executive are sidelined in the promotions, remunerations and reward. The study makes relevant conclusions and recommendations. “The remuneration of the judges is not sufficient to induce the ablest lawyers in the prime of life to accept judicial office. If that state of affairs is allowed to continue it must have serious effect upon the administration of the law. It will impair those intellectual standards which have made our English legal system a great legal system; it will tend to impair that law abiding instinct which is the condition precedent for the maintenance of a high standard of civilization, and it will weaken the chief remaining guarantee for the prosecution of the liberties of that subject.”1 With reflection on the above statement on remuneration, this piece of work discusses remuneration systems and promotion possibilities and how to reward efficient and independent judges from the Ugandan perspective.

Flame retardants can be incorporated into polymeric material either as additives or as reactive materials. Additive type flame retardants are widely used by means of blending them with a specific polymeric material. In this particular research, hexachlorocylodiphosphazane derivatives type (I-II) were synthesized for use as flame retardant and antimicrobial additives with epoxy varnish. These additives are physically incorporated into the epoxy varnish formula. Experimental coatings were manufactured on a laboratory scale and applied by brush on wood and steel panels. The fire retardant ability of each coating type was characterized using the limiting oxygen index (LOI) test. The mechanical properties of these flame retardants were also examined to evaluate the drawbacks of the additives. Results of the LOI indicated that coating with these compounds containing chlorine, nitrogen and phosphorus exhibit a very good retardant effect, when blended with epoxy varnish comparing with the blanket sample which not contain on the hexachlorocylodiphosphazane derivative as a additives. The hexachlorocylodiphosphazane derivative also exhibit mild results as preservative against microbiological attack. The mechanical properties of the painted dry films were investigated acordinting to ASTM.
