Published: May 2016

Background: Medical male circumcision (MMC) has become a significant dimension of HIV prevention interventions, after the results of three randomised controlled trials in Uganda, South Africa and Kenya demonstrated that circumcision has a protective effect against contracting HIV of up to 60%. Following recommendations by the World Health Organization, Zimbabwe in 2009 adopted voluntary MMC as an additional HIV prevention strategy to the existing ABC behaviour change model.Purpose: The purpose of this study is thus to investigate the factors contributing to the low uptake of MMC.Methods: The study was a quantitative cross-sectional survey conducted in Mutare rural district, Zimbabwe. Questionnaires with open- and closed-ended questions were administered to the eligible respondents. The target population were male participants aged 15–29 who met the inclusion criteria. The households were systematically selected with a sample size of 234. Statistical Package for the Social Sciences was used to analyse the data.Results: Socioculturally, circumcised men are viewed as worthless (37%), shameful (30%) and are tainted as promiscuous (20%), psychological factors reported were infection and delayed healing (39%), being ashamed and dehumanised (58%), stigmatised and discriminated (40.2%) and fear of having an erection during treatment period (89.7%) whilst socio-economic factors were not having time, as it will take their time from work (58%) and complications may arise leading to spending money on treatment (84%).Conclusion: Knowledge deficits regarding male medical circumcision lead to low uptake, education on male medical circumcision and its benefits. Comprehensive sexual health education should target men and dispel negative attitudes related to the use of health services.Keywords: Factors, Low uptake, Medical Male Circumcision (MMC)

Abstract
OBJECTIVE. To examine the internal reliability and test–retest reliability of the Client-Centeredness of Goal Setting (C–COGS) scale.
METHOD. The C–COGS scale was administered to 42 participants with acquired brain injury after completion of multidisciplinary goal planning. Internal reliability of scale items was examined using item–partial total correlations and Cronbach’s α coefficient. The scale was readministered within a 1-mo period to a subsample of 12 participants to examine test–retest reliability by calculating exact and close percentage agreement for each item.
RESULTS. After examination of item–partial total correlations, test items were revised. The revised items demonstrated stronger internal consistency than the original items. Preliminary evaluation of test–retest reliability was fair, with an average exact percent agreement across all test items of 67%.
CONCLUSION. Findings support the preliminary reliability of the C–COGS scale as a tool to evaluate and promote client-centered goal planning in brain injury rehabilitation.

Abstract. A data set containing more than 6 years (February 2009 to present) of radiance spectra for carbon dioxide (CO2) and methane (CH4) observations has been acquired by the Greenhouse gases Observing SATellite (GOSAT, available at http://data.gosat.nies.go.jp/GosatUserInterfaceGateway/guig/GuigPage/open.do), nicknamed “Ibuki”, Thermal And Near infrared Sensor for carbon Observation Fourier Transform Spectrometer (TANSO-FTS). This paper provides updates on the performance of the satellite and TANSO-FTS sensor and describes important changes to the data product, which has recently been made available to users. With these changes the typical accuracy of retrieved column-averaged dry air mole fractions of CO2 and CH4 (XCO2 and XCH4, respectively) are 2 ppm or 0.5 % and 13 ppb or 0.7 %, respectively. Three major anomalies of the satellite system affecting TANSO-FTS are reported: a failure of one of the two solar paddles in May 2014, a switch to the secondary pointing system in January 2015, and most recently a cryocooler shutdown and restart in August 2015. The Level 1A (L1A) (raw interferogram) and the Level 1B (L1B) (radiance spectra) of version V201 described here have long-term uniform quality and provide consistent retrieval accuracy even after the satellite system anomalies. In addition, we discuss the unique observation abilities of GOSAT made possible by an agile pointing mechanism, which allows for optimization of global sampling patterns.
Franco Lelli y la rebelión bubi de 1998: historia y testimonio en OKIRI
Authors: Licata Stefanía 
Published: June 2016

A través de un acercamiento teórico al género del testimonio y, partiendo de los estudios de John Beverly y Dori Laub, el presente ensayo se propone analizar la novela Okiri (2005) de Franco Lelli, que relata los acontecimientos en torno a la rebelión bubi de 1998 en Guinea Ecuatorial e informa sobre el Movimiento para la Autodeterminación de la Isla de Bioko (MAIB), que se constituyó en 1993. La novela nace de la urgencia de denunciar las injusticias que han oprimido al pueblo bubi, grupo étnico originario de la isla de Bioko, ya desde la independencia de España en 1968; másespecíficamente, el relato se centra en las violaciones de los derechos humanos por el régimen dictatorial de Teodoro Obiang Nguema, en el poder desde el 3 de agosto de 1979 hasta el presente. Evidenciaré la voluntad documental de la novela, única memoria histórica escrita del acontecimiento, además de subrayar los rasgos subjetivos y testimoniales del relato y distinguirlos de los recursos literarios. Tendré en cuenta la experiencia particular como testigo del autor de la novela, Franco Lelli, que vive la misma atmósfera de represión durante la revuelta, no obstante no forma parte del grupo bubi. El análisisde Okiri no sólo contribuye a la reconstrucción histórica de la rebeldía de 1998 del pueblo bubi, sino que añade otros rasgos al género testimonial.
Pratiques déclarées d’enseignants d’histoire au secondaire en lien avec leurs usages des ressources didactiques et l’exercice de la méthode historique
Authors: Boutonnet Vincent 
Published: June 2016

L’article propose une analyse descriptive de pratiques déclarées d’enseignants d’histoire au secondaire en lien avec leurs usages des ressources didactiques et l’exercice de la méthode historique. Nous proposons une analyse complémentaire d’un sondage sur les fonctions déclarées par 81 enseignants du Québec. Le sondage permet d’identifier différents types d’usages selon les réponses données : intensif, extensif, critique. Le type extensif est majoritaire et s’appuie sur un usage diversifié et partiel de ressources didactiques. Cependant, la place de la méthode historique, de l’interprétation et de la critique est plutôt faible, puisque l’usage extensif des ressources sert davantage à illustrer et exposer les faits par le contrôle exercé par l’enseignant sur la structuration du savoir historique. Les fonctions attribuées par ces enseignants ne semblent pas varier selon leurs années d’expérience.
How do Catalan Students Narrate the History of Catalonia When They Finish Primary Education?

Published: June 2016

In this article we analyze how a group of Catalan students (aged 11-13,N = 245) narrate the history of Catalonia and we compare their narratives with the official Catalan narrative. From an interpretative approach, we collect data by requiring the students to write down what they remember about the history of Catalonia. The research is conducted by means of narrative analysis and normative content analysis. Our results suggest that most students’ narratives are similar to the official narrative in terms of the main characters and events selected and follow the patriotic national narrative by highlighting the relevance of Catalan national symbols. We discuss the implications of this patriotic national narrative in Catalonia and elsewhere, and we propose replacing patriotic national narratives with humanistic world history narratives.

Distinct effects of anthropogenic aerosols on the East Asian summer monsoon between multidecadal strong and weak monsoon stages

Published: May 2016

AbstractBecause industrial emissions of anthropogenic aerosols over East Asia have greatly increased in recent decades, the interactions between atmospheric aerosols and the East Asian summer monsoon (EASM) have attracted enormous attention. To further understand the aerosol‐EASM interaction, we investigate the impacts of anthropogenic aerosols on the EASM during the multidecadal strong (1950–1977) and weak (1978–2000) EASM stages using the Community Atmospheric Model 5.1. Numerical experiments are conducted for the whole period, including the two different EASM stages, with present day (PD, year 2000) and preindustrial (PI, year 1850) aerosol emissions, as well as the observed time‐varying aerosol emissions. A comparison of the results from PD and PI shows that, with the increase in anthropogenic aerosols, the large‐scale EASM intensity is weakened to a greater degree (−9.8%) during the weak EASM stage compared with the strong EASM stage (−4.4%). The increased anthropogenic aerosols also result in a significant reduction in precipitation over North China during the weak EASM stage, as opposed to a statistically insignificant change during the strong EASM stage. Because of greater aerosol loading and the larger sensitivity of the climate system during weak EASM stages, the aerosol effects are more significant during these EASM stages. These results suggest that anthropogenic aerosols from the same aerosol emissions have distinct effects on the EASM and the associated precipitation between the multidecadal weak and strong EASM stages.
Late Cretaceous intraplate silicic volcanic rocks from the Lake Chad region: An extension of the Cameroon volcanic line?

Published: May 2016

AbstractSilicic volcanic rocks at Hadjer el Khamis, near Lake Chad, are considered to be an extension of the Cameroon volcanic line (CVL) but their petrogenetic association is uncertain. The silicic rocks are divided into peraluminous and peralkaline groups with both rock types chemically similar to within‐plate granitoids. In situ U/Pb zircon dating yielded a mean 206Pb/238U age of 74.4 ± 1.3 Ma indicating the magmas erupted ∼10 million years before the next oldest CVL rocks (i.e., ∼66 Ma). The Sr isotopes (i.e., ISr = 0.7021–0.7037) show a relatively wide range but the Nd isotopes (i.e., 143Nd/144Ndi = 0.51268–0.51271) are uniform and indicate that the rocks were derived from a moderately depleted mantle source. Thermodynamic modeling shows that the silicic rocks likely formed by fractional crystallization of a mafic parental magma but that the peraluminous rocks were affected by low temperature alteration processes. The silicic rocks are more isotopically similar to Late Cretaceous basalts identified within the Late Cretaceous basins (i.e., 143Nd/144Ndi = 0.51245–0.51285) of Chad than the uncontaminated CVL rocks (i.e., 143Nd/144Ndi = 0.51270–0.51300). The age and isotopic compositions suggest the silicic volcanic rocks of the Lake Chad region are related to Late Cretaceous extensional volcanism in the Termit basin. It is unlikely that the silicic volcanic rocks are petrogenetically related to the CVL but it is possible that magmatism was structurally controlled by suture zones that formed during the opening of the Central Atlantic Ocean and/or the Pan‐African Orogeny.

Published: May 2016

AbstractThe last 125 Myr capture major changes in the chemical composition of the ocean and associated geochemical and biogeochemical cycling. The sulfur isotopic composition of seawater sulfate, as proxied in marine barite, is one of the more perplexing geochemical records through this interval. Numerous analytical and geochemical modeling approaches have targeted this record. In this study we extend the empirical isotope record of seawater sulfate to therefore include the two minor sulfur isotopes, 33S and 36S. These data record a distribution of values around means of Δ33S and Δ36S of 0.043 ± 0.016‰ and −0.39 ± 0.15‰, which regardless of δ34S‐based binning strategy is consistent with a signal population of values throughout this interval. We demonstrate with simple box modeling that substantial changes in pyrite burial and evaporite sulfate weathering can be accommodated within the range of our observed isotopic values.
A Conductive Hybridization Matrix of RuO2 Two‐Dimensional Nanosheets: A Hybrid‐Type Photocatalyst

Published: May 2016

AbstractA universal methodology to efficiently improve the photocatalyst performance of semiconductors was developed by employing exfoliated RuO2 two‐dimensional nanosheets as a conducting hybridization matrix. The hybridization with a RuO2 nanosheet is easily achieved by crystal growth or electrostatically derived anchoring of semiconductor nanocrystals on the RuO2 nanosheet. An enhanced chemical interaction of inorganic semiconductor with hydrophilic RuO2 nanosheet is fairly effective in optimizing their photocatalytic activity and photostability by the enhancement of charge separation and charge mobility. The RuO2‐containing nanohybrids show much better photocatalyst functionalities than do the graphene‐containing ones. The present study clearly demonstrates that hydrophilic RuO2 nanosheets are superior hybridization matrices, over the widely used hydrophobic graphene nanosheets, for exploring new efficient hybrid‐type photocatalysts.

AbstractRegio‐ and enantioselective additions of alcohols to either terminal allenes or internal alkynes provides access to allylic ethers by using a RhI/diphenyl phosphate catalytic system. This method provides an atom‐economic way to obtain chiral aliphatic and aryl allylic ethers in moderate to good yield with good to excellent enantioselectivities.
Sequence‐Dependent Photocurrent Generation through Long‐Distance Excess‐Electron Transfer in DNA

Published: May 2016

AbstractGiven its well‐ordered continuous π stacking of nucleobases, DNA has been considered as a biomaterial for charge transfer in biosensors. For cathodic photocurrent generation resulting from hole transfer in DNA, sensitivity to DNA structure and base‐pair stacking has been confirmed. However, such information has not been provided for anodic photocurrent generation resulting from excess‐electron transfer in DNA. In the present study, we measured the anodic photocurrent of a DNA‐modified Au electrode. Our results demonstrate long‐distance excess‐electron transfer in DNA, which is dominated by a hopping mechanism, and the photocurrent generation is sequence dependent.
Overexpression of caveolin‐1 in inflammatory breast cancer cells enables IBC‐specific gene delivery and prodrug conversion using histone‐targeted polyplexes
Authors: Ross Nikki L. , Sullivan Millicent O. 
Published: May 2016

ABSTRACTGene therapy platforms offer a variety of potentially effective solutions for development of targeted agents that can be exploited for cancer treatment. The physicochemical properties of nanocarriers can be tuned to enhance their localization in tumors, and cell specificity can also be increased by appropriate selection of gene targets. A relatively underexploited approach to enhance therapeutic selectivity in cancer tissues is the use of nanocarriers whose nuclear targeting and uptake are triggered by the altered expression of specific endomembrane trafficking proteins in cancer cells. Previously, we showed that histone 3 (H3) peptide‐targeted DNA polyplexes traffic to the nucleus efficiently through caveolar endocytosis followed by transfer through the Golgi and endoplasmic reticulum (ER). We hypothesized that these polyplexes would exhibit enhanced activity in inflammatory breast cancer (IBC) cells, which overexpress caveolin‐1 as part of their invasive phenotype, and we also posited that this targeting effect could be exploited to facilitate IBC‐specific transfection and prodrug conversion in the presence of normal breast epithelial cells. Using cellular transfection experiments, function‐blocking assays, and confocal imaging in both IBC SUM149 cell monocultures and IBC SUM149 co‐cultures with MCF10A normal breast epithelial cells, we found that our H3‐targeted polyplexes selectively transfected IBC SUM149 cells at a 4‐fold higher level than normal breast epithelial cells. This selectivity and increased transfection were caused by a 2.2‐fold overexpression of caveolin‐1 in IBC SUM149 cells, which led to increased polyplex trafficking to the nucleus through the Golgi and ER. We also saw similar enhancements in cell selectivity and transfection when cells were transfected with a suicide gene/prodrug combination, as the increased expression of the suicide gene in IBC SUM149 cells led to a 55% decrease in viability in IBC SUM149 cells as compared to a 25% decrease in MCF10A cells. These findings demonstrate that differences in the expression of the endocytic membrane protein caveolin‐1 can be exploited for cell‐selective gene delivery, and ultimately, these gene‐based targeting approaches may be useful in potential treatments for aggressive cancer types.

AbstractThis study establishes structure–property relationships for four synthetic flavin molecules as bioinspired redox mediators in electro‐ and photocatalysis applications. The studied flavin compounds were disubstituted with polar substituents at the N1 and N3 positions (alloxazine) or at the N3 and N10 positions (isoalloxazines). The electrochemical behavior of one such synthetic flavin analogue was examined in detail in aqueous solutions of varying pH in the range from 1 to 10. Cyclic voltammetry, used in conjunction with hydrodynamic (rotating disk electrode) voltammetry, showed quasi‐reversible behavior consistent with freely diffusing molecules and an overall global 2e−, 2H+ proton‐coupled electron transfer scheme. UV/Vis spectroelectrochemical data was also employed to study the pH‐dependent electrochemical behavior of this derivative. Substituent effects on the redox behavior were compared and contrasted for all the four compounds, and visualized within a scatter plot framework to afford comparison with prior knowledge on mostly natural flavins in aqueous media. Finally, a preliminary assessment of one of the synthetic flavins was performed of its electrocatalytic activity toward dioxygen reduction as a prelude to further (quantitative) studies of both freely diffusing and tethered molecules on various electrode surfaces.
