Published: October 2020

La terapia de la tuberculosis con el esquema 2RHZE/4HE comprende la administración durante seis meses de rifampicina, isoniazida, pirazinamida y etambutol, de las cuales las tres primeras son potencialmente hepatotoxicas y excepcionalmente nefrotoxicas. La tuberculosis produce depleción de la concentración de zinc lo que incrementa la susceptibilidad a la cronicidad de la infección. Objetivo: evaluar el efecto de la administración conjunta de zinc y la terapia 2RHZE/4HE sobre la función hepática y renal en pacientes con tuberculosis pulmonar. Métodos: estudio descriptivo de tipo caso control, doble ciego aleatorizado con 22 pacientes con tuberculosis pulmonar en terapia farmacológica y 22 controles sanos reclutados en los centros de salud Sebastián pagador y Alalay. Los pacientes fueron divididos aleatoriamente en dos grupos a los que se les administró zinc (45mg/día) o placebo durante tres meses. En todos los pacientes se tomó muestras de sangre antes y después de la intervención para medir pruebas de función renal y hepática. En los sujetos control la muestra de sangre se tomó al inicio del estudio para realizar las mismas determinaciones. Resultados: no se encontró deferencias en la concentración de marcadores específicos de daño hepático o renal. Conclusiones: la adición de un suplemento diario de 45mgr de zinc a la terapia 2RHZE/4HE no produjo daño renal ni hepático en las personas evaluadas.

Andrić and Bašagić in the Yugoslavian Key
Authors: Filandra Šaćir
Published: November 2020

The different views on identity politics in Ottoman Bosnia presented by Ivo Andrić and Safvet-beg Bašagić in their respective doctoral dissertations stem from differences in the historical and socio-economic experiences of each of their respective religious and confessional communities. Andrić, oriented towards the future, perceives Bosnia from the perspective of a newly introduced concept of Yugoslav national unity that does not value diversity. Bašagić, romantically looking into the past, sees Bosnia through rose-coloured glasses. Both Andrić and Bašagić share distinct notions of their historical periods and allow for non-scientific influences to shape their academic discourses.
Consociationalism in the post-Dayton Bosnia and Herzegovina
Authors: Karić Mirsad
Published: November 2020

This paper outlines the theoretical underpinnings of the consociational power-sharing approach and its presence in the political system of the post-Dayton Bosnia and Herzegovina. The power-sharing framework used in this study provides insights into the theory of consociationalism as a power-sharing approach and tries to contribute to our understanding of the presence and relevance of this model to the Bosnian political system. The consociational framework emphasises the role of the political elites in providing the political stability and economic prosperity in the heterogeneous societies. It has four main features: grand coalition, proportional representation, segmental autonomy and mutual veto. The functioning and performance of this model depends, to a large extent, on factors that are conducive to elite cooperation. These factors are: population size, balance of power among segments, multiparty system, segmental isolation, nature of social cleavages, overarching loyalties and tradition of elite accommodation. This paper shows that all features of consociationalism exist in the post-Dayton Bosnian political system. However, grand coalitions are always made after the elections and mainly for the distribution of positions in the executive bodies of state apparatus and without any strategic platform and goals to be achieved and accounted for, agreed in advance. Proportionality has been mainly replaced with the parity-giving rise to imbalanced representation in state institutions. Segmental autonomy has been misconceived and veto power has been used to block all legislation beneficial to the state.

Abstract. Ice-nucleating particles (INPs) affect the microphysics in cloud and precipitation processes. Hence, they modulate the radiative properties of clouds. However, atmospheric INP concentrations of the past are basically unknown. Here, we present INP measurements from an ice core in Greenland, which dates back to the year 1370. In total 135 samples were analyzed with the FRIDGE droplet freezing assay in the temperature range from −14 to −35 ∘C. The sampling frequency was set to 1 in 10 years from 1370 to 1960. From 1960 to 1990 the frequency was increased to one sample per year. Additionally, a few special events were probed, including volcanic episodes. The typical time coverage of a sample was on the order of a few months. Historical atmospheric INP concentrations were estimated with a conversion factor, which depends on the snow accumulation rate of the ice core, particle dry deposition velocity, and wet scavenging ratio. Typical atmospheric INP concentrations were on the order of 0.1 L−1 at −25 ∘C. The INP variability was found to be about 1–2 orders of magnitude. Yet, the short-term variability from samples over a seasonal cycle was considerably lower. INP concentrations were significantly correlated to some chemical tracers derived from continuous-flow analysis (CFA) and ion chromatography (IC) over a broad range of nucleation temperatures. The highest correlation coefficients were found for the particle concentration (spherical diameter dp > 1.2 µm). The correlation is higher for a time period of seasonal samples, where INP concentrations follow a clear annual pattern, highlighting the importance of the annual dust input in Greenland from East Asian deserts during spring. Scanning electron microscopy (SEM) analysis of selected samples found mineral dust to be the dominant particle fraction, verifying their significance as INPs. Overall, the concentrations compare reasonably well to present-day INP concentrations, albeit they are on the lower side. However, we found that the INP concentration at medium supercooled temperatures differed before and after 1960. Average INP concentrations at −23, −24, −25, −26, and −28 ∘C were significantly higher (and more variable) in the modern-day period, which could indicate a potential anthropogenic impact, e.g., from land-use change.
Influence of gravity wave temperature anomalies and their vertical gradients on cirrus clouds in the tropical tropopause layer – a satellite-based view
Authors: Chang Kai-Wei , L'Ecuyer Tristan
Published: October 2020

Abstract. Negative temperature perturbations (T′) from gravity waves are known to be favorable to tropical tropopause layer (TTL) clouds, and recent studies have further suggested a possible role of dT′/dz in facilitating TTL cloud formation and maintenance. With a focus on exploring the influence of dT′/dz on TTL clouds, this study utilizes radio occultation temperature retrievals and cloud layers from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) to understand how gravity wave perturbations modulate cloud occurrence in the tropics. Cloud populations were evaluated in four phases corresponding to positive or negative T′ and dT′/dz. We find that 55 % of TTL clouds are found where T′ and dT′/dz are both negative. Regions of frequent convection are associated with higher cloud populations in the warm phase T′>0. We show that the partitioning of cloud population among wave phases exhibits dependence on background relative humidity. In the phase where T′ and dT′/dz are both negative, the mean cloud effective radius is the smallest of all four phases, but the differences are small. It is shown that the strongest mean negative T′ anomaly is centered on the cloud top, resulting in positive dT′/dz above the cloud top and negative dT′/dz below. This negative T′ anomaly propagates downward with time, characteristic of upward propagating gravity waves. Negative (positive) T′ anomalies are associated with increased (decreased) probability of being occupied by clouds. The magnitude of T′ correlates with the increase or decrease in cloud occurrence, giving evidence that the wave amplitude influences the probability of cloud occurrence. While the decrease in cloud occurrence in the warm phase is centered on the altitude of T′ maxima, we show that the increase in cloud occurrence around T′ minima occurs below the minima in height, indicating that cloud formation or maintenance is facilitated mainly inside negative dT′/dz. Together with existing studies, our results suggest that the cold phase of gravity waves is favorable to TTL clouds mainly through the region where dT′/dz is negative.

Taihu eddy flux network, a network consisting of seven lake sites and one
land site. Lake Taihu is the third-largest freshwater lake (area of 2400 km2) in China, under the influence of subtropical climate. The dataset
spans the period from June 2010 to December 2018. Data variables are saved
as half-hourly averages and include micrometeorology (air temperature,
humidity, wind speed, wind direction, rainfall, and water or soil temperature
profile), the four components of surface radiation balance, friction
velocity, and sensible and latent heat fluxes. Except for rainfall and wind
direction, all other variables are gap-filled, with each data point marked by
a quality flag. Several areas of research can potentially benefit from the
publication of this dataset, including evaluation of mesoscale weather
forecast models, development of lake–air flux parameterizations,
investigation of climatic controls on lake evaporation, validation of remote-sensing surface data products and global synthesis on lake–air
interactions. The dataset is publicly available at https://yncenter.sites.yale.edu/data-access (last access: 24 October 2020) and from the Harvard Dataverse
(https://doi.org/10.7910/DVN/HEWCWM; Zhang et al., 2020).
Inventory of dams in Germany
Authors: Speckhann Gustavo Andrei , Kreibich Heidi , Merz Bruno
Published: October 2020

Abstract. Dams are an important element of water resources management. Data about dams are crucial for practitioners, scientists and policymakers for various purposes, such as seasonal forecasting of water availability or flood mitigation. However, detailed information on dams on the national level for Germany is so far not freely available. We present the most comprehensive, open-access dam inventory for Germany (DIG) to date. We have collected and combined information on dams using books, state agency reports, engineering reports, and internet pages. We have applied a priority rule that ensures the highest level of reliability for the dam information. Our dam inventory comprises 530 dams in Germany with information on name, location, river, start year of construction and operation, crest length, dam height, lake area, lake volume, purpose, dam structure and building characteristics. We have used a global, satellite-based water surface raster to evaluate the location of the dams. A significant part (63 %) of dams has been built between 1950–2013. Our inventory shows that dams in Germany are mostly single-purpose (52 %), 53 % can be used for flood control, and 25 % are involved in energy production. The inventory will be freely available through GFZ Data Services (https://doi.org/10.5880/GFZ.4.4.2020.005) after discussion. In the meantime the data can be downloaded using the following temporary link https://dataservices.gfz-potsdam.de/panmetaworks/review/09c134e13a7ede5d80d67f641d615698c05917fac25fc776240a110d2df96a66/ (Speckhann et al., 2020).
Global maps of Forel-Ule index, hue angle and Secchi disk depth
derived from twenty-one years of monthly ESA-OC-CCI data

Published: October 2020

Abstract. We document the development and public release of a new dataset (1997–2018), consisting of global maps of the Forel-Ule index, hue angle and Secchi disk depth. Source data comes from the European Space Agency (ESA) Ocean Colour (OC) Climate Change Initiative (CCI), which is providing merged multi-sensor data from the mid-resolution sensors in operation at a specific time from 1997 to the present day. Multi-sensor satellite datasets are advantageous tools for ecological studies because they increase the probabilities of cloud-free data over a given region, as data from multiple satellites whose overpass times differ by a few hours are combined. Moreover, data merging from heritage and present satellites can expand the duration of the time series indefinitely, which allows the calculation of significant trends. Additionally, data are remapped consistently and analysis-ready for scientists. Also, the products described in this article have the exclusive advantage of being linkable to in-situ historic observations and thus enabling the construction of very long time series. Monthly data are presented at a spatial resolution of ~4 km at the equator and are available at PANGAEA, https://doi.org/10.1594/PANGAEA.904266 (Pitarch et al., 2019a). Two smaller and easier to handle test datasets have been produced from the former: a global dataset at 1 degree spatial resolution and another one for the North Atlantic at 0.25 degree resolution.
Laboratory observations on meltwater meandering rivulets on ice
Authors: Fernández Roberto , Parker Gary
Published: October 2020

Abstract. We present a set of observations on meltwater meandering rivulets on ice and compare them (qualitatively and quantitatively) to morphologies commonly found in meandering channels in different media. The observations include data from planned centimeter-scale experiments, and from incidental self-formed millimeter-scale rivulets. Our data show pulsed lateral migration features, undercut banks and overhangs, meander bend skewness, and meander bend cutoffs. The data also compare well with planform characteristics of alluvial meandering rivers (sinuosity, wavelength-to-width ratios, and meander bend fatness and skewness). We discuss the (ir)relevance of scale in our experiments, which in spite of being in the laminar flow regime, and are likely affected by surface tension effects, are capable of shedding light into the processes driving formation and evolution of supraglacial meltwater meandering channels. Our observations suggest that sinuosity growth in meltwater meandering channels on ice is a function of flow velocity and the interplay between vertical and lateral incision driven by temperature differences between flow and ice. In the absence of recrystallization (depositional analog to alluvial rivers), bends are more likely to be downstream skewed and channels show lower sinuosities.
The Impact of Seismic Interpretation Methods on the Analysis
of Faults: A Case Study from the Snøhvit Field, Barents Sea
Authors: Cunningham Jennifer , Cardozo Nestor , Townsend Chris , Callow Richard
Published: October 2020

Abstract. Five seismic interpretation experiments were conducted on an area of interest containing a fault relay in the Snøhvit field, Barents Sea, Norway, to understand how interpretation method impacts the analysis of fault and horizon morphologies, fault lengths, and vertical displacement (throw). The resulting horizon and fault interpretations from the least and most successful interpretation methods were further analysed to understand the impact of interpretation method on geological modelling and hydrocarbon volume calculation. Generally, the least dense manual interpretation method of horizons (32 inlines (ILs) x 32 crosslines (XLs), 400 m) and faults (32 ILs, 400 m) resulted in inaccurate fault and horizon interpretations and underdeveloped relay morphologies and throw that can be considered inadequate for any detailed geological analysis. The densest fault interpretations (4 ILs, 50 m) and auto-tracked horizons (1 IL x 1 XL, 12.5 m) provided the most detailed interpretations, most developed relay and fault morphologies and geologically realistic throw distributions. Analysis of the geological modelling proved that sparse interpretation grids generate significant issues in the model itself which make it geologically inaccurate and lead to misunderstanding of the structural evolution of the relay. Despite significant differences between the two models the calculated in-place petroleum reserves are broadly similar in the least and most dense experiments. However, when considered at field-scale the magnitude of the differences in volumes that are generated solely by the contrasting interpretation methodologies clearly demonstrates the importance of applying accurate interpretation strategies.
The Influence of Attendance, Communication, and Distractions on the Student Learning Experience using Blended Synchronous Learning
Authors: Vale Julie , Oliver Michele , Clemmer Ryan M. C.
Published: October 2020

A second-year engineering course at the authors’ institution was offered via a blended synchronous learning (BSL) method of delivery whereby students could choose to attend lectures live (face-to-face) or remotely (via a synchronous, live stream over the internet) during a summer semester. Survey and grade data were collected across two years of this offering. Attendance, interaction, communication with the instructor, and general distractions were main themes affecting the student learning experience both positively and negatively. Specifically, students found the remote access, the ability to ask questions, the teaching style, and having more time during the summer semester as positive aspects to their learning experience. Negative influences on their learning experience related primarily to their busy work schedules, technological issues associated with BSL, and typical summer distractions. Critically, our results indicate that attendance is a key indicator of student grades (after correcting for GPA), regardless of whether students attended lectures remotely or face-to-face: students attending more than 75% of the lectures performed on average 12% better than students who did not (p=0.0093). The consensus in the student comments was that the remote attendance option allowed students to attend in situations where the alternative was no attendance at all, implying that the potential gain in grades due to higher attendance may outweigh any potential impact the mode of attendance may have. Overall, a synchronous, remote attendance option may provide a lifeline to students who would not otherwise be able to attend a course, and (assuming a mode of interaction, such as the synchronous chat, is available) students do not perceive remote attendance as having a negative influence on their learning.
A World Café Discussion on Well-Being: Considerations for Life in the University
Authors: McDermott Mairi , Simmons Marlon , Lock Jennifer , Kenny Natasha
Published: October 2020

How are universities conceptualizing and mobilizing well-being on their campuses? Our qualitative inquiry explores growing challenges of addressing educator mental health and well-being on university campuses. As part of an effort to increase awareness and support around issues of mental health and well-being at one university, a campus-wide strategy was announced in 2015. This article follows up on that strategy to understand how university educators come to identify with well-being. We collected composite anonymized data from a World Café discussion with a range of educators. The goals of the World Café discussion were to: (a) highlight campus-wide conversations on educator mental health and well-being; (b) explore multiple perspectives and make sense of how educators experience mental health and well-being; (c) create a space to nurture meaningful relationships; (d) inform the continued development of research, strategies, and policies to support educator mental health and well-being. We share four themes that emerged from the discussions to consider well-being and life in the university: (a) affective, relational and holistic aspects “in search of well-being”; (b) working through the messiness of well-being: risks and vulnerabilities; (c) inviting people into a culture of well-being; and (d) the role of leaders in moving beyond policy towards enactment.
Joining a Scholarly Conversation: Publishing Your SoTL Work
Authors: Normandeau Magdalen , Kolomitro Klodiana , Maher Patrick T.
Published: October 2020

The path to publication is often long, emotional, and bewildering. We share key insights from our experience as authors, educators, and members of the editorial board with The Canadian Journal for the Scholarship of Teaching and Learning that we hope will help authors better understand and navigate the path to publication. In writing a compelling story, we suggest that it is necessary to join a conversation with self, the scholarly community, and the journal. We unpack each of these dimensions and offer considerations on how to craft a powerful manuscript that could ultimately get published.
The Attitudes of the Young towards Social Media
Authors: Ertekin Alpaslan Baki , Avunduk Yesim
Published: November 2020

This study aimed to investigate the attitudes of young individuals towards social media. The study sample consisted of 391 university students studying at different faculties (172 males and 219 females) and with an age average of 22.47±2.29. The participants were selected using the appropriate sampling method, which is one of the non-random sampling methods. The data collection tools involved a personal information form and the “Social Media Attitude Scale” developed by Otrar and Argın (2015). Descriptive statistics were applied to determine the distribution of personal information (e.g., frequency, arithmetic mean, standard deviation) and the Shapiro Wilks normality test to check whether the data had a normal distribution. Since the data were appropriate for parametric tests, an independent t-test and ANOVA were applied to find the differences in social media use by specific demographic characteristics. According to the study findings, there was a significant difference in social media use by gender and faculty (p < 0.05), but no significant difference was found by age (p > 0.05). It was concluded that the participants' attitudes towards social media varied by only gender and faculty.

Published: November 2020

In the wake of the COVID-19 pandemic, food policy councils (FPCs) have emerged as a critical struc¬ture for organizing community-based responses to multiple food system issues. Strong relationships with various food system stakeholders have proven essential in inspiring coordinated action. Using the early results of a Johns Hopkins Center for a Livable Future survey of FPCs (2020), we discuss some of the accomplishments and contributions that 118 FPCs have made toward addressing hunger and supporting producers, school food, food chain workers, racial equity, and resilience in the United States and in tribal nations.
Emerging Gender, Media and Technology Scholarship in Africa: Opportunities and Conundrums in African Women’s Navigating Digital Media
Authors: Gadzekpo Audrey , Gardner Paula , Steeves H. Leslie
Published: October 2020

Over the past decade and earlier, much of the academic and grey literature has painted an optimistic picture of rapidly increasing access and growth of digital technologies in Africa. Industry statistics put internet penetration in Africa close to 40 percent and growing, even though the continent still lags behind the world average of Internet users (Internet World Statistics, June 2019). Some estimates predict that by 2025 the sub-continent will add 167 million mobile subscribers to its existing 456 million (GSMA Report, 2019). Mobile devices, especially, have assumed centrality in the lives of ordinary people and provide prospects for Africa to leapfrog into the modern digital world. Smart phones are enabling millions of Africans to share news and information more easily and to tap into all kinds of essential services, much like elsewhere in the world.
Framing the Other: Rethinking Media Representations of Mursi Women’s Display of Gendered Lip-Plated Bodies
Authors: Atuhura Dorothy
Published: October 2020

With illustrations drawn from Ilja Kok and Willem Timmers’s documentary Framing the Other (2012), this article rethinks media representation of the contact between Mursi lip-plated women of Ethiopia and Western tourists who come to sightsee and photograph their traditionally modified bodies. The film Framing the Other represents this contact as a destructive force that has not only enabled Mursi women’s victimhood as objects of the tourist gaze, but one that has contributed negative cultural change and loss of tradition. In this article, I provide an alternative, if not oppositional, interpretation that only attends to the nuanced ways Mursi women negotiate cultural loss and change, and recognizes modalities of agential tactics they deploy to negotiate cultural exchange and perform identity work within a cross-cultural contact zone marred with significant inequalities that work to their (dis)advantage. I do not imply that my reading will provide a definitive reading; rather, I reexamine the vanishing tradition and victimhood narratives portrayed in Framing the Other, showing that its multiple layers of meaning in fact motivate an oppositional and alternative reading.
A Feminist Reading of Hashtag Activism in Ghana
Authors: Mohammed Wunpini Fatimata
Published: October 2020

This article examines Akumaa Mama Zimbi’s activism in the Ghanaian social media landscape, specifically Twitter. I argue that while it is imperative to critique her hashtag activism for its complicity with patriarchal ideology in the repression of female sexuality, it is important to contextualize her work within conversations on gender activism and feminisms in Ghana. This article parses out the politics of and tensions in feminist movements on the continent demonstrating how certain activist labels can be depoliticized and used to undo decades of feminist work on the continent. By drawing on my lived experience as an ethnically marginalized Muslim woman born and raised in Ghana who is active in the country’s digital (activist) public sphere, I present a critical analysis of the pervasive conversations on gender activism and feminism in Ghana. I employ the conceptual framework of framing to examine the main topics that arise out of Akumaa’s #WearYourDrossNow campaign on Ghana Twitter which aims at discouraging young women from engaging in premarital sex. I assert that Akumaa’s work is inspired by her personal interpretation of gender activism and is closely tied to religious morality and conservative notions of female sexuality in Ghana.
