Accepting Research: Teachers' Representations of Participation in Educational Research Projects
Authors: Richard Vincent , Bélanger Michel 
Published: May 2018

<p style="text-align: justify;">Collecting data among participants belonging to a group, community or organization is a crucial step in social research. However, generally speaking, in the social sciences, the issue of access to the research field has not been widely or systematically studied and remains under-theorized. The goal of this study is to draw the participants’ perspective on the question of accepting research into their classrooms and participating in it, an object that has usually been overlooked in studies on research field access. This article presents the results of a qualitative, exploratory study aimed at documenting teachers’ representations relating to whether or not they wish to participate in research projects, when requested to do so by researchers. The analysis brought out a system comprising five categories of representations relating to participation or non-participation in an educational research project. These representations are related to 1) the teacher’s daily tasks; 2) the teacher's professional development; 3) the teacher's professional identity and professional ideal; 4) the institutional and collegial context; and 5) the teacher's responsibility toward students. We discuss these categories and their implications for further research. </p>

Published: May 2018

<p style="text-align:justify">The purpose of this research is to assess the sports and socialization of the students studying in different sports branches in Gumushane University. “Socialization- Sports and Socialization Scale” developed by Sahan was used in this research. A total of 742 students composed of 316 females and 426 males studying in Gumushane University participated in this survey modelled research. Data obtained were evaluated in SPSS package program. Reliability coefficient of the scale was found to be 0.896. T-Test, Kruskall Wallis and Anova were used in statistical assessment of data. Pearson Product-Moment Correlation analysis was used to determine whether there was a significant relation between socialization and sports-socialization scores and the causal relations between two variables were tested with simple linear regression analysis. The study was analyzed in terms of certain variables and it was concluded that the variables of gender, age, place of residence and type of sports done by the participants didn’t make a difference on sports-socialization and socialization scores. It is also observed that there is a positive and significant relation between the variables of socialization and sports-socialization (r= .624, p<.01). In other words, it can be stated that the higher the socialization scores of the participants are, the higher their sports-socialization scores become, accordingly. </p>
The Design of ACE (Aluminum Corrosion and Electrolysis) Reactor and Its Performance to Produce Hydrogen from Beverage Cans
Authors: Zikri Ahmad , . Erlinawati , Trisnaliani Lety , Wulandari Daya 
Published: May 2018

AbstractThe reaction of aluminum (Al) with an alkaline solution in producing hydrogen gas has been known for a long time. This aluminum corrosion reaction has a major obstacle in the passivation phenomenon, a formation of aluminum oxide coating on the metal surface that prevents aluminum from collapsing. Integration of electric current to the potassium hydroxide solution could result in electrolysis of water which increases the production of hydrogen. This process was carried out continuously in an ACE (aluminum corrosion and electrolysis) reactor of water. This reactor design enabled to produce hydrogen and oxygen in separating chamber. The use of 10 g of cans, 0.02 M gallium, 12 VDC, and 0.8 M KOH obtained the maximum production rate of hydrogen 162.58 ml/s with a purity of 79.83%.

Encapsulation Rutin with Chitosan-NATPP Using Coaservation Method
Authors: Cahyono Bambang , Suzery Meiny , Hadiyanto H , Bela Pratiwi Sestri 
Published: May 2018

Abstract This study aims to make microparticles of rutin compounds at various concentrations with NaTPP-chitosan as matrix. Encapsulation is done by coaservation method. The success of encapsulation was identified by UV-Vis spectrophotometry, Fourier Transform Infra-Red (FTIR) spectroscopy and Scanning electron microscopy (SEM). Based on UV-Vis spectrophotometry analysis, the efficiency of encapsulation (EE) and loading capacity (LC) was obtained at 62,43-94,36 and 1,73% -32,1%, at rutine concentration 0,625-11,25 mM. The success of rutin encapsulation is demonstrated by the rutin characteristics of the product seen with the presence of peaks of aromatic rings, indicating the presence of rutin compounds contained in the chitosan matrix. SEM analysis shows rough and porous surface morphology in microcapsules. The rutin release profile of the microcapsules is described as two phase processes, burst release at the initial discharge in the first 30 min followed by slow release. At the highest LC (11.25 mM concentration), it provides greater discharge rates for both synthetic fluid simulations 77.53 ± 3.59% and 78.76 ± 4.00% after 3h of discharge. The controlled release data showed high discharge rates at acidic pH than alkaline pH. Keywords: Rutin, encapsulation, citosan, coaservation
Tourists’ perceived value of wildlife tourism product at Lake Nakuru National Park, Kenya

Published: May 2018

Abstract
Although literature has documented many destination attributes that determine attractiveness of tourism destination, the magnitude and strength of each attribute has not been explored, especially in relation to a single wildlife tourism product. This study provides an insight into the level of tourists’ perceived value on wildlife resource attributes at Lake Nakuru National Park in Kenya, with a further comparison between the international and domestic tourists. The study adopted a cross-sectional survey and collected primary data using self-administered structured questionnaires. A total of 402 respondents duly completed the questionnaires, which were disseminated through simple random sampling. Data was analysed descriptively and through independent sample T-test. The results showed that unique wildlife attractions were most valued by tourists (M = 2.26, SD = 0.99), followed by the variety of attractions (M = 2.53, SD = 1.08) and their abundance (M = 2.59, SD = 1.19) respectively. Majority of international tourists highly valued the attributes [M = 2.30, SD = 0.88; t(400) = 4.18, p < 0.001] as compared to the domestic tourists (M = 2.67, SD = 0.88), but with a small magnitude (η = 0.04). The study provides an insight that tourists value the park because of its uniqueness due to a variety of wildlife attractions. As park ecological challenges persist, park managers may re-brand the park by creating more emphasis on other key wildlife products like rhinos in order to maintain visitor value and satisfaction in the future.
Agreement with locatives in Kinyarwanda: a comparative analysis
Authors: Zeller Jochen , Ngoboka J. Paul 
Published: May 2018

AbstractIn Bantu languages such as Chichewa or Herero, locatives can function as subjects and show noun class agreement (in class 16, 17 or 18) with predicates and modifiers. In contrast, (preverbal) locatives in Sotho-Tswana and Nguni have been analysed as prepositional adjuncts, which cannot agree. Our paper compares locatives in Kinyarwanda (JD61) with locatives in these other Bantu languages and demonstrates that the Kinyarwanda locative system is essentially of the Chichewa/Herero type. We show that Kinyarwanda locatives are nominal in nature, can act as subjects, and agree with predicates and modifiers. However, even though Kinyarwanda has four locative noun classes (16, 17, 18 and 25), there is only one locative agreement marker (class 16ha-), which indiscriminately appears with all locatives, regardless of their noun class. We explain this fact by arguing that noun class features in Kinyarwanda do not participate in locative agreement; instead, the invariant class 16 marker expresses agreement with a generic feature [location] associated with all locatives. We offer a syntactic analysis of this peculiar aspect of Kinyarwanda locative agreement, and we propose a parameter that accounts for the relevant difference between Kinyarwanda and Chichewa/Herero-type Bantu languages.
War Elephants and Early Tanks: A Transepochal Comparison of Ancient and Modern Warfare
Authors: Searle Alaric 
Published: May 2018

Abstract
Although scholars have in the past dismissed the claim that war elephants were the »tanks of the ancient world«, a closer examination of the similarities between the two weapons reveals some remarkable parallels. In fact, a comparison shows that many of the counter-measures in anti-elephant warfare in antiquity had parallels in anti-tank warfare in the Great War. More importantly, the upward spiral of increased weapon power, followed by defensive countermeasures, then an increase in the protective armour added to the »weapons system«, is a process which can be observed in the evolution of both war elephants and early tanks. The comparison raises questions about the dominant narrative in the history of the tank, largely instigated by J. F. C. Fuller, namely, that its invention represented a revolution in the history of warfare since it spelled the transition from animal and human muscular power to machine power. This article seeks to explain why Fuller always avoided drawing comparisons between war elephants and tanks; and, it argues that specific types of military phenomena can be identified which recur in different historical epochs.

Published: May 2018

Abstract
Intracranial aneurisms are ongoing problem for neurosurgeons and especially for interventional neuroradiologists due to its morbidity and mortality. The method of choice for treatment of the unruptured and ruptured intracranial aneurysms is endovascular coiling on account of its minimal invasiveness and high effectiveness. The aim of our study was to evaluate the safety and successfulness of endovascular coiling procedure in unruptured and ruptured intracranial aneurysms.
Our study was designed as case series and consisted of patients older than 18 years, who underwent endovascular coiling of unruptured and ruptured intracranial aneurysms and follow-up examination 6 months after the interventional procedure. The procedures were performed from December 2010 to December 2016, by experienced interventional neuroradilogists (more than 400 performed embolizations each) at the Department for Interventional Neuroradiology, Clinical Center Kragujevac, Serbia.
There were 681 patients (average age 47.5 ± 11.2 years) treated with endovascular coiling, out of them 324 (234 females, 90 males) had unruptured intracranial aneurysm and 357 (138 females, 219 males) had ruptured intracranial aneurysm. In our series, total complication rate was 11.71 %. Analysis of the results after first endovascular procedure has shown that complete aneurysm occlusion was accomplished in 546 patients (80.3%), near-complete in 81 patients (11.8%), and incomplete in 54 patients (7.9 %).
Our results were satisfying regarding the procedure’s success, safety, outcomes and study material. However, further technical development of the materials and constant training of the interventional radiologists, are a necessity in order to improve treatment outcomes and patients’ benefit.

Published: May 2018

Abstract
The objective of the present paper was the assessment of the chemical composition of the essential oils from four Asteraceae species with a considerable food, medicinal, and agricultural value, collected in Egypt, together with their in vitro inhibitory activity against molds and yeasts. The essential oil of Launaea cornuta flowers was also evaluated for the first time, but because of its very low yield (<0.01%), no antifungal test was performed.
Effect of yeast extract addition to a mineral salts medium containing hydrolyzed plant xylan on fungal pullulan production
Authors: Kennedy II Daniel E. , West Thomas P. 
Published: May 2018

Abstract
The ability of the fungus Aureobasidium pullulans ATCC 42023 to produce pullulan from yeast extract-supplemented xylan hydrolysates of the prairie grass prairie cordgrass was examined relative to polysaccharide and cell biomass production, yield, and pullulan content of the polysaccharide. A pullulan concentration of 11.2 g L−1 and yield of 0.79 g g−1 was produced by ATCC 42023 when grown for 168 h at 30°C on the phosphate-buffered hydrolysate supplemented with yeast extract. The highest biomass level being 8.8 g L−1 was produced by ATCC 42023 after 168 h on a yeast extract-supplemented, hydrolysate-containing complete medium lacking sodium chloride. The highest pullulan content of the polysaccharide produced by ATCC 42023 after 168 h on the hydrolysate medium supplemented with yeast extract and ammonium sulfate was 70%. The findings indicate that a polysaccharide with a high pullulan content can be produced at a relatively high yield by the fungus grown on a yeast extract-supplemented xylan hydrolysate, suggesting that pullulan could be produced using a biomass-based process.
“Termites in the Temple”: Fundamentalism and Anti-Liberal Politics in the Post–World War II South
Authors: Fones-Wolf Elizabeth , Fones-Wolf Ken 
Published: May 2018

AbstractFrom 1946 to 1950, East Tennessee was embroiled in a bitter campaign over the radio preacher and evangelist, J. Harold Smith. More than a curiosity, this confrontation helps us understand a much broader struggle that cut deeply through American society in the post-World War II era. It was a conflict that grew out of a conservative political effort to roll back the New Deal, the union-led regime of collective bargaining, and the tide of modernist religion. These issues overlapped with concerns about African-American equality and the Soviet Union’s threat to the nation’s security. Although recent scholarship has revealed the symbiotic relationship between postwar evangelicalism and free-enterprise ideology, we know little about how and why that message resonated for many middling and working-class individuals. Fortunately, supporters of Smith’s radio program wrote thousands of letters that illuminate what normally anonymous people were thinking about God, society, and politics in the postwar years.In this paper, we use the events in Knoxville as a window into the broader contest over religion and politics in postwar America. Smith’s struggle in Knoxville occurred during an especially tumultuous time in the South. As such, it reveals one regional context for the unsettling political changes and religious conflicts that were occurring nationally. Finally, a study of the responses of Smith’s supporters affords a rare opportunity to analyze one base of postwar fundamentalism and what drew them to the politics and theology of men like J. Harold Smith.
Key Transport and Ammonia Recycling Genes Involved in Aphid Symbiosis Respond to Host-Plant Specialization
Authors: Kim Dohyup , Minhas Bushra F , Li-Byarlay Hongmei , Hansen Allison K 
Published: May 2018

AbstractMicrobes are known to influence insect-plant interactions; however, it is unclear if host-plant diet influences the regulation of nutritional insect symbioses. The pea aphid, Acyrthosiphon pisum, requires its nutritional endosymbiont, Buchnera, for the production of essential amino acids. We hypothesize that key aphid genes that regulate the nutritional symbioses respond to host-plant diet when aphids feed on a specialized (alfalfa) compared to a universal host-plant diet (fava), which vary in amino acid profiles. Using RNA-Seq and whole genome bisulfite sequencing, we measured gene expression and DNA methylation profiles for such genes when aphids fed on either their specialized or universal host-plant diets. Our results reveal that when aphids feed on their specialized host-plant they significantly up-regulate and/or hypo-methylate key aphid genes in bacteriocytes related to the amino acid metabolism, including glutamine synthetase in the GOGAT cycle that recycles ammonia into glutamine and the glutamine transporter ApGLNT1. Moreover, regardless of what host-plant aphids feed on we observed significant up-regulation and differential methylation of key genes involved in the amino acid metabolism and the glycine/serine metabolism, a metabolic program observed in proliferating cancer cells potentially to combat oxidative stress. Based on our results, we suggest that this regulatory response of key symbiosis genes in bacteriocytes allows aphids to feed on a suboptimal host-plant that they specialize on.
HermesTransposon Mutagenesis Shows [URE3] Prion Pathology Prevented by a Ubiquitin-Targeting Protein: Evidence for Carbon/Nitrogen Assimilation Cross Talk and a Second Function for Ure2p inSaccharomyces cerevisiae
Authors: Edskes Herman K , Mukhamedova Maryam , Edskes Bouke K , Wickner Reed B 
Published: May 2018

Abstract[URE3] is an amyloid-based prion of Ure2p, a regulator of nitrogen catabolism. While most “variants” of the [URE3] prion are toxic, mild variants that only slightly slow growth are more widely studied. The existence of several antiprion systems suggests that some components may be protecting cells from potential detrimental effects of mild [URE3] variants. Our extensive Hermes transposon mutagenesis showed that disruption of YLR352W dramatically slows the growth of [URE3-1] strains. Ylr352wp is an F-box protein, directing selection of substrates for ubiquitination by a “cullin”-containing E3 ligase. For efficient ubiquitylation, cullin-dependent E3 ubiquitin ligases must be NEDDylated, modified by a ubiquitin-related peptide called NEDD8 (Rub1p in yeast). Indeed, we find that disruption of NEDDylation-related genes RUB1, ULA1, UBA3, and UBC12 is also counterselected in our screen. We find that like ylr352wΔ [URE3] strains, ylr352wΔ ure2Δ strains do not grow on nonfermentable carbon sources. Overexpression of Hap4p, a transcription factor stimulating expression of mitochondrial proteins, or mutation of GLN1, encoding glutamine synthetase, allows growth of ylr352w∆ [URE3] strains on glycerol media. Supplying proline as a nitrogen source shuts off the nitrogen catabolite repression (NCR) function of Ure2p, but does not slow growth of ylr352wΔ strains, suggesting a distinct function of Ure2p in carbon catabolism. Also, gln1 mutations impair NCR, but actually relieve the growth defect of ylr352wΔ [URE3] and ylr352wΔ ure2Δ strains, again showing that loss of NCR is not producing the growth defect and suggesting that Ure2p has another function. YLR352W largely protects cells from the deleterious effects of otherwise mild [URE3] variants or of a ure2 mutation (the latter a rarer event), and we name it LUG1 (lets [URE3]/ure2 grow).

Abstract

Lesson Learned
Panitumumab plus irinotecan is not active for the treatment of esophageal adenocarcinoma.

Background
Esophageal adenocarcinoma (EAC) is a lethal cancer with increasing incidence. Panitumumab (Pa) is a fully humanized IgG2 monoclonal antibody against human EGFR. Cetuximab (Cx) combined with irinotecan (Ir) is active for second-line treatment of colorectal cancer. This phase II study was designed to evaluate Pa plus Ir as second-line therapy for advanced EAC.

Methods
The primary endpoint was response rate (RR). Patients with one prior treatment were given Pa 9 mg/m2 on day 1 and Ir 125 mg/m2 on days 1 and 8 of each 21-day cycle. Inclusion criteria were confirmed EAC, measurable disease, no prior Ir or Pa, performance status &lt;2, and normal organ function.

Results
Twenty-four patients were enrolled; 18 were eligible and evaluable. These patients were all white, with a median age of 62.5 years (range, 33–79 years), and included 15 men and 3 women. The median number of cycles was 3.5. The most common grade 1–2 adverse events were fatigue, diarrhea, anemia, leukopenia, and hypoalbuminemia. Grade 3–4 adverse events included hematologic, gastrointestinal, electrolyte, rash, fatigue, and weight loss. The median follow-up was 7.2 months (range, 2.3–14 months). There were no complete remissions. The partial response rate was 6% (1/18; 95% confidence interval [CI], 0.01–0.26). The clinical benefit (partial response [PR] plus stable disease [SD]) rate was 50%. The median overall survival was 7.2 months (95% CI, 4.1–8.9) with an 11.1% 1-year survival rate. The median progression-free survival was 2.9 months (95% CI, 1.6–5.3).

Conclusion
Irinotecan and panitumumab as second-line treatment for advanced EAC are not active.
