Streambank Legacy Sediments in Surface Waters: Phosphorus Sources or Sinks?
Authors: Inamdar Shreeram , Sienkiewicz Nathan , Lutgen Alyssa , Jiang Grant , Kan Jinjun
Published: May 2020

Streambank legacy sediments can contribute substantial amounts of sediments to Mid-Atlantic waterways. However, there is uncertainty about the sediment-bound P inputs and the fate of legacy sediment P in surface waters. We compared legacy sediment P concentrations against other streambank sediments and upland soils and evaluated a variety of P indices to determine if legacy sediments are a source or sink of P to surface waters. Legacy sediments were collected from 15 streambanks in the mid-Atlantic USA. Total P and M3P concentrations and % degree of phosphorus saturation (DPS) values for legacy sediments were lower than those for upland soils. % DPS values for legacy sediments were below the water quality threshold for P leaching. Phosphorus sorption index (PSI) values for legacy sediments indicated a large capacity for P sorption. On the other hand, equilibrium phosphorus concentration (EPC0) for legacy sediments suggested that they could be a source or a sink depending on stream water P concentrations. Anoxic conditions resulted in a greater release of P from legacy sediments compared to oxic conditions. These results suggest that legacy sediment P behavior could be highly variable and watershed models will need to account for this variability to reliably quantify the source-sink behavior of legacy sediments in surface waters.
Anaerobic Power Assessment in Athletes: Are Cycling and Vertical Jump Tests Interchangeable?
Authors: Gross Micah , Lüthy Fabian
Published: May 2020

Regularly assessing anaerobic power is important for athletes from sports with an explosive strength component. Understanding the differences and overlap between different assessment methods might help coaches or smaller-scale testing facilities maximize financial and temporal resources. Therefore, this study investigated the degree to which cycling sprint and vertical jump tests are interchangeable for determining peak mechanical leg power output in strength-trained athletes. Professional skiers (n = 19) performed unloaded squat jumps (SJ) and other jump forms on a force plate and a six-second cycling sprint (6sCS) test on an ergometer on six occasions over two years. Along with cross-sectional correlations between cycling and jumping power, correlations between longitudinal percent changes and agreement between magnitude-based inferences about individual changes were assessed. Among the tested jump forms, SJ reflected 6sCS best. However, despite extremely large cross-sectional correlation coefficients (0.92) between 6sCS and SJ, and moderate (Pearson’s r = 0.32 for 6sCS with SJ over one-year time spans) to large (r = 0.68 over shorter time spans) correlation coefficients on percent changes, magnitude-based inferences agreed in only around 50% of cases. Thus, for making qualitative assessments about the development of anaerobic power over time in athletes, cycling sprint and squat jump tests are not interchangeable. Rather, we recommend employing the test form that best reflects athletes’ strength and conditioning training.

Published: May 2020

The 2008 global economic crisis heightened social inequality and drastically reduced equal opportunities for many people. It had negative consequences for social regulation in many European countries, which have dismantled their public social policies. The objective of the study was to describe social workers’ perceptions of their lived experiences in different areas of the public social services system. A qualitative study was developed, based on a hermeneutic approach. Six in-depth interviews and two focus groups were conducted with 20 social workers employed by community social services and the Andalusian public health service (Spain). The professionals agreed that the public social services system has been eroded, that the lack of resources has consequences for workers and the general public alike, and that the public authorities and the administration are responsible for this situation. Social services have become distributors of scarce resources rather than a social protection system that empowers and accompanies the most vulnerable. The system must provide the necessary resources and structures so that they can escape the situation of poverty, exclusion and social injustice.

Published: May 2020

During the last decade, the demand for electricity has increased significantly, both for companies and consumers. Therefore, in every country, there are companies developing and functioning to provide various forms of electric energy. The quality of the services that they provide has been of major concern for these companies for the last few years. The objective of this study is to examine residential customers’ satisfaction of electricity providers in Greece regarding various factors, such as the products, services, customer service, and the pricing policy. The present research was conducted with the use of a specially developed website questionnaire; 689 questionnaires were collected from January to June, 2019. The results were analyzed with the multicriteria satisfaction analysis (MUSA) method, which is considered as an aggregation–disaggregation approach developed on the qualitative analysis regression. The results of the study showed that the residential customers were quite satisfied. More specifically, the average global satisfaction index of the residential customers was about 52.15%. Using the results of this study, electricity providers will have the chance to frame their future products and services so as to keep their industrial customers satisfied. This empirical study may serve as a reference for other electricity providers who desire to carry out similar studies in the future.

Published: May 2020

The residential location choice of the highly educated population is an important consideration to construct a livable city. While landscape and environment are important factors, few studies have deeply analyzed the spatial heterogeneity effects of landscape and environment on the residential location choices of a highly educated population. Taking Guangzhou as the sample, we built a livability-oriented conceptual framework of landscape and environment, and constructed datasets for highly educated population proportion, landscape, and environment factors, and other influencing factors for Guangzhou’s 1364 communities. Global regression and geographically weighted regression (GWR) models are used for analysis. The GWR model is more effective than the global regression model. We found spatial heterogeneity in the strength and direction of the relationship between the highly educated population proportion and landscape and environment. We find that landscape and environment exert spatial heterogeneity effects on the residential location choice of the highly educated population in Guangzhou. The conclusions will be of reference value to further understand how the spatial limitations of landscape and environment affect residential location choices. This study will help city managers formulate spatially differentiated environment improvement policies, thereby increasing the city’s sustainable development capabilities.

Published: May 2020

Rapid growth in industrial development has raised the concern of proper disposal of the by-products generated in industries. Many of them may cause serious pollution to the air, land, and water if dumped in open landfills. Agricultural and municipal wastes also cause environmental issues if not managed properly. Besides, minimizing the carbon footprint has become a priority in every industry to slow down global warming and climate change effects. The use of supplementary cementitious materials (SCMs) obtained from agricultural, industrial, municipal, and natural sources can decrease a significant amount of fossil fuel burning by reducing cement production and contribute to proper waste management. Also, SCMs can enhance desirable material properties like flowability, strength, and durability. Such materials may play a big role to meet the need of modern time for resilient construction. The effective application of SCMs in cement-based materials requires a clear understanding of their physical and chemical characteristics. Researchers studied how the flowability, strength, and durability properties of structural mortar change with the replacement of cement with different SCMs. Various experiments were conducted to examine the behavior of structural mortar in extreme conditions (e.g., high temperature). Many scholars have attempted to improve its performance with various treatment techniques. This article is an attempt to bring all the major findings of the recent relevant studies together, identify research gaps in the current state of knowledge on the utilization of SCMs in structural mortar, and give several recommendations for further study. The available results from recent studies have been reviewed, analyzed, and summarized in this article. A collection of the updated experimental findings will encourage and ease the use of various by-products and wastes as SCMs in structural mortar for sustainable construction.

Published: May 2020

In the context of climate and environmental change assessment, the use of probabilistic models in which the parameters of a given distribution may vary in accordance with time has reinforced the need for appropriate procedures to recognize the “statistical significance” of trends in data series arising from stochastic processes. This paper introduces a parametric methodology, which exploits a measure based on the Akaike Information Criterion (AICΔ), and a Rescaled version of the Generalized Extreme Value distribution, in which a linear deterministic trend in the position parameter is accounted for. A Monte Carlo experiment was set up with the generation of nonstationary synthetic series characterized by different sample lengths and covering a wide range of the shape and scale parameters. The performances of statistical tests based on the parametric AICΔ and the non-parametric Mann-Kendall measures were evaluated and compared with reference to observed ranges of annual maxima of precipitation, peak flow, and wind speed. Results allow for sensitivity analysis of the test power and show a strong dependence on the trend coefficient and the L-Coefficient of Variation of the parent distribution from the upper-bounded to the heavy-tailed special cases. An analysis of the sample variability of the position parameter is also presented, based on the same generation sets.

Published: May 2020

SPIRALS program was designed in accordance with the inclusive Universal Design for Learning approach and the social cognitive model of self-regulated learning. This project aims to promote cognitive, emotional, and behavioral engagement among elementary students, and especially those at high risk of dropping out (such as Roma students). To test the efficacy of the program, an intervention study was performed for four months within a truly inclusive learning environment, involving the whole classes. A quasi-experimental pre-test/post-test design with a control group (n = 63) and an experimental group (n = 57) was used. The dependent variables were student engagement (cognitive, emotional, and behavioral), academic self-concept, perceived climate of support, reading comprehension, and academic performance. Students in the experimental group exhibited statistically significant improvements compared to the control group in six of the seven dependent variables analyzed (behavioral and emotional engagement, academic self-concept, perceived climate of support, reading comprehension, and academic performance). Further, the magnitude of differences tended to be larger in student engagement, perceived climate of support, and reading comprehension than in academic self-concept or academic performance. These results provide evidence supporting the usefulness of intervention programs aimed at promoting student engagement, specifically among students at higher risk of failure or dropout.
Effects of Land-Use and Land-Cover Change on Nitrogen Transport in Northern Taihu Basin, China during 1990–2017

Published: May 2020

Different land uses have varying degrees of impact on nitrogen transport in the catchments. In recent decades, rapid urbanization has dramatically changed the Earth’s land surface, which may cause excessive nitrogen losses and a negative influence on the environment. In the long-term scale, it is important to explore how the nitrogen transport responds to land use change and its effects on aquatic habitats. In this study, the water and sediment samples were collected from northern Taihu Basin, and nine periods of land use data were obtained using the techniques of supervised classification. Results revealed that the proportion of farmland area decreased from 28.33% to 7.09%, while that of constructed land area increased from 23.85% to 61.72% during 1990–2017. Most of the constructed land originated from farmland, which makes it the dominant land use type due to rapid urbanization. In spatial distribution, high total nitrogen (TN) losses regions remain distributed over constructed land and farmland, which may aggravate the trend of local water quality deterioration. Of these regions, constructed land was the dominant contributor (46.29%–63.62%) of TN losses from surface runoff. In temporal variation, the TN losses of runoff decreased by 47% from 175 t N·a−1 in 1990. However, they increased by 2.91% from 75.28 t N·a−1 after 2013 with rapid population growth and high fertilizer application (>570 kg·ha−1). The nitrogen load in sediments also has a significant response (t = 2.43, p = 0.02) to the effects of land use change on the overlying water, indicating that the role of nitrogen in the sediment as a source and/or sink to the waterbody may change frequently. Given the increasing accumulation of nitrogen loads in highly urbanized regions, water quality would cause more aggravation in the long-term without reasonable land management measures.
You Are What You Eat: The Relationship between Values and Organic Food Consumption

Published: May 2020

In current times, the man-made problems affecting our planet (climate change, loss of biodiversity, etc.) are making an urgent case for shifting towards a more sustainable kind of consumption. One of the ways these problems can be addressed is to promote organic agriculture, which means boosting levels of organic food consumption. This study examines the relationship between the number of organic foods consumed and the specific values that consumers look for in foods, in order to deepen the current knowledge regarding the behaviour of the organic food consumer. To this end, data was analysed from a face-to-face survey of 776 people in Spain through bivariate analysis techniques. Results show that organic food consumers have a different pattern of values from non-consumers and a greater level of involvement with food in general. Moreover, within the group of organic consumers, the effect of values on the quantity or variety of foods consumed is not as marked, although there are differences in favour of those that consume more frequently. Lastly, the main implication of the results obtained is that, in order to increase consumption, selfish values should be connected with altruistic ones. For this reason, instilling a specific value based on the term or concept “life” is proposed.
The Importance of Being Local: The Role of Authenticity in the Concepts Offered by Non-Themed Domestic Restaurants in Switzerland

Published: May 2020

In the highly-competitive restaurant environment, restaurateurs continually optimize the quality of their offer so that customers leave the restaurant with the intention to return and to tell others about their experience. Authenticity is among the attributes that restaurateurs seek to provide; and a wealth of study has been conducted to understand authenticity in a variety of contexts including ethnic-themed restaurants. However; insufficient attention has been given to non-themed domestic restaurants; which make up a significant proportion of available dining options. This study aimed to explore the role of authenticity as part of the concepts offered by domestic restaurants in Switzerland. Interviews with managers of 30 domestic restaurants were analyzed according to their content and interpreted according to authenticity dimensions identified by Karrebaek and Maegaard (2017) and Coupland and Coupland (2014). The approach of using a framework with four dimensions—“tradition”, “place”, “performance”, and “material”—was a useful epistemological lens to view the construct of authenticity. Participants from country restaurants placed more importance on tradition, while restaurateurs from both country and urban restaurants emphasized the importance of seasonal and regional ingredients and of fitting the restaurant within the cultural and geographical landscape. Managers of domestic restaurants in Switzerland see authenticity as a way of attracting and retaining customers, which can thereby contribute to the economic sustainability of restaurants, although the participants cautioned that customer expectations of sufficient choice can outweigh the added value of authenticity. Authenticity of the product offered by domestic restaurants can also contribute to the sustainability of place by enabling continuity of cultural heritage and traditions. These results provide a basis for future research that could guide restaurateurs’ decisions of how to include authenticity when developing and implementing their concepts for domestic restaurants.
Utilising Enterprise Social Media for Product Innovation: The Role of Market Orientation
Authors: Mpandare Magadlene , Li Guoxin
Published: May 2020

The literature on the role of enterprise social media (ESM) utilisation in driving the innovation profiles of organisations has not provided an understanding of the mechanisms of this positive relationship. By conceptualising ESM as including internal and external social media use, this study examined the mediating role of market orientation strategies in the link between ESM use and product innovation. The results of structural equation modeling, among a sample of organisations based in South Africa, show that ESM use positively affects the market orientation strategies of companies and these have a positive effect on product innovation. While inter-functional coordination does not mediate the external social media–product innovation link, it does so in the internal social media–product innovation link. These results imply that organisations that wish to pursue product innovation (and perhaps strategies of differentiation) should use ESM, leveraging their value in knowledge generation and assimilation.

Published: May 2020

The aim of this study is to investigate the decision-making mechanism of reusable mobile phone trading behaviors by using the extended theory of planned behavior. In this study, based on the survey data of 964 residents in Beijing, China and structural equation modeling method, the main factors that affect consumers’ reusable mobile phone trading behavior and their degree of influence were analyzed, followed by discussion on decision-making mechanisms. The findings show that consumers’ behavioral selection has been significantly related to four intrinsic subjective factors and fifteen external objective factors, and the combined effect of the latter ones is nearly triple of that of the former ones. Moreover, the observed variables of environmental awareness, information leakage sensitivity, trading convenience and consumer trading returns are the four most significant factors. The impact of active trading behavior is not significant. However, this may be because that there were no great trading rewards, lack of trading awareness and regulations. Finally, the study put forward relevant policy recommendations for improving the comprehensive management of recycling reusable mobile phones, and provides a theoretical reference for improving the recycling rate of reusable mobile phones.
Do Loan Guarantees Alleviate Credit Rationing and Improve Economic Welfare?
Authors: Wang Yu-Lin , Lee Chien-Hui , Ko Po-Sheng
Published: May 2020

By designing credit contracts with inversely related interest rates and collateral, banks can overcome the problems of adverse selection and moral hazard when there is an informational asymmetry in competitive credit markets. One salient result points out that, if borrowers’ insufficient endowments of wealth cause a binding collateral constraint, a credit rationing equilibrium arises because of collateral’s inability to achieve perfect sorting. The purpose of this paper is to examine the consequences of government loan guarantees on equilibrium credit contracts and economic welfare. More specifically, the effects of loan guarantees on interest rates, collateral, and credit rationing were studied. Our results suggest that government loan guarantees should target high-risk entrepreneurs. Loan guarantees targeting high-risk entrepreneurs reduce a pledge of collateral in credit contracts, drop social cost, and increase economic welfare. Under the circumstances that borrowers’ insufficient wealth causes a binding collateral constraint, loan guarantees targeting high-risk entrepreneurs alleviate the problem of credit rationing and improve economic welfare.

Published: May 2020

In early December 2019, the coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first emerged in Wuhan, China. As of May 10th, 2020, a total of over 4 million COVID-19 cases and 280,000 deaths have been reported globally, reflecting the raised infectivity and severity of this virus. Amongst hospitalised COVID-19 patients, there is a high prevalence of established cardiovascular disease (CVD). There is evidence showing that COVID-19 may exacerbate cardiovascular risk factors and preexisting CVD or may lead to cardiovascular complications. With intensive care units operating at maximum capacity and such staggering mortality rates reported, it is imperative during this time-sensitive COVID-19 outbreak to identify patients with an increased risk of adverse outcomes and/or myocardial injury. Preliminary findings from COVID-19 studies have shown the association of biomarkers of acute cardiac injury and coagulation with worse prognosis. While these biomarkers are recognised for CVD, there is emerging prospect that they may aid prognosis in COVID-19, especially in patients with cardiovascular comorbidities or risk factors that predispose to worse outcomes. Consequently, the aim of this review is to identify cardiovascular prognostic factors associated with morbidity and mortality in COVID-19 and to highlight considerations for incorporating laboratory testing of biomarkers of cardiovascular performance in COVID-19 to optimise outcomes.
Persons and Things in Marseille and Lucca, 1300-1450
Authors: Smail Daniel Lord
Published: May 2020

In later medieval Europe, a rising tide of wealth changed the material regime and, with it, the relationships that defined the matrix of persons and things. Some of our best evidence for the changes afoot in the era can be found in the massive documentation generated by the legal institutions of the period. Featured in this chapter are household inventories and inventories of debt collection from the cities of Marseille and Lucca. Although the things found in these documents are not tangible, the approach known as “documentary archaeology” allows us to treat the words that describe them as fragments or traces left by things that once existed. Many of the things found in people’s houses were used for the purposes of social distinction, whether that means the individual pursuit of prestige or status, through competitive consumption and display, or a group’s pursuit of group identity, through the display of badges or totems that define membership in a group. The use of materiality for the purposes of distinction has a deep natural history. But in exploring distinction, it is important to bear in mind that prestige goods had other affordances and lent themselves to other ends. Particularly prominent in many human societies, including that of later medieval Europe, is the capacity for things to serve as stores of value. Also important is the fact that people form emotional connections with things. The complex nature of the relationship between people and things in the later Middle Ages is best understood if we treat things as part of the extended phenotype of persons, or as part of a matrix or network that treats both humans and things as equivalent nodes.

Introduction. Environmental analysis is an integral part of the enterprise planning study, both in the current period and in the strategic perspective. Nowadays managers should take into account the dynamism of changes in the external environment, described as the rapid change of the situation at the product markets (both national and international), sectoral transformations, related, first of all, to changes in the regulatory field, framework conditions, technical and organizational prerequisites for the production of products, which has a direct impact on the activity of an enterprise and determines the nature of changes in its internal environment. Therefore, a deep and comprehensive study of the external environment’s features has a decisive influence on the formation of strategy for enterprise’s development.
Purpose. The article aims to conduct comprehensive diagnostics of the external environment of wood pellet exporters in Ukraine and to justify a range of strategic decisions related to stock logistics and marketing of the products.
Method (methodology). The methodological basis of the article was the general scientific and empirical methods of scientific research, such as: systematics, method of generalization, grouping, method of expert evaluation, as well as PEST-analysis.
Results. The determining factors, which influence the formation of the strategic management system of wood pellet manufacturers, are determined. The next proposals are necessary: the improvement in stock logistics and marketing activities, levelling risks associated with exchange rate fluctuations, in the context of solving complex issues of foreign economic activity of enterprises (contracting, forming clients bases and bases of counterparties, improvement of transport infrastructure, etc.). The proposal for independent management of changes in the field of technical and technological support is made, which directly determines compliance with the criteria of product quality, and defines its prospects for development in the medium and long term.

Published: May 2020

Introduction. Labor market is a major component of any economy and is intricately tied in with markets for capital, goods and services. At a time of immense challenges to sustainable development, employment, unemployment, particularly youth unemployment, gender inequalities are major concerns and key challenges.
Purpose. The article aims is to research the national peculiarities and tendencies of the labor market and determine the directions of the state policy of Ukraine for regulating the asymmetries of its development on the basis of foreign countries experience.
Method (methodology): the methods of structural and logical analysis were used to implement theoretical generalizations and formulation of mechanisms for regulating them in the context of achieving the Sustainable Development Goals; the methods of detailing and synthesis were used to study the employment, unemployment, wages, and labor migration. The statistical methods were used to study the labor market asymmetries and the trends of labor market.
Results. The actual trends of development of labor market have been investigated. There are a number of problems that affect the efficiency of state policy and achieving the Global goals of sustainable development. These are problems such as employment opportunities, especially for young people; inequalities across regions, age groups and genders; informal employment; labor migration.
Particular importance is attached to core indicators for reporting on contribution towards implementation of the Sustainable Development Goals as annual growth rate of real GDP per employed person; proportion of informal employment, by sex; average hourly earnings of female and male employees, by occupation, age and persons with disabilities; unemployment rate, by sex, age and persons with disabilities; proportion of youth (aged 15-24 years) not in education, employment or training.
The mechanisms of regulation of asymmetries of development of labor market in Ukraine are proposed. For example, labor market reform and revision of labor law; investing in education; development of cognitive and social skills; job creation, cooperation of all parties of social-labor relations and others.

Background: Depression is very common in women, especially  on reproductive age. It is estimated that 14% -23% of pregnant women experience depression during pregnancy, and 5% -25% experience postpartum depression. Mothers with caesarean sectio labor experience high scale pain during the first 24 hours. Objective : this study aims to analyze the relationship between caesarean section labor and postpartum depression in primiparous mothers. Methods: The research method used is descriptive analytic with cross-sectional approach. The sample in this study were 20 postpartum caesarean mothers in Yogyakarta City Hospital taken by purposive sampling. Data collection tools in this study are using the Numeric Category Scale (NCS) questionnaire to measure the level of neyri and the Edinburgh Postnatal Depression Scale (EPDS) to measure the level of depression of respondents. Analysis using the Chi-Square correlation test.  Results: Most of the level of pain in postpartum SC mothers is in the moderate category that is there are 9 people or (45.0%). Most postpartum mothers in the moderate depression category were 9 people or (45.0%). Statistical results with the Chi Square test showed that there was a significant relationship between labor pain in caesarean section and postpartum depression in primiparous mothers with (p-value = 0.002) (p <0.05). Conclusion: There is a relationship between labor pain in caesarean section and postpartum depression in primiparous mother.

Background: helminthiasis is classified as negleted disease, which is an infection that is not considered and is chronic without causing clear clinical symptoms and its effects can only be seen in the long term. Objective: to identify the types of worms in the feces of Kendari garbage transportation workers. Methods: uses laboratory observation methods to identify the type of Soil that is Contagious. Using 42 stool samples that have been stored for ± 2 months were taken from the stools of Kendari municipal waste workers and examined using the modified kato-katz, Harada Mori and Direct slide methods. Results: the results of various inspection methods namely, direct slide, Kato-katz modification and Harada Mori modification. Identification of the egg stage, the p-value is 0.002 <α = 0.05. This shows that the Kato-katz method is far better than the direct shear method in the examination of STH worm eggs. The p-value results in the examination of Harada mori larvae and the direct shear value were 0.001 <α = 0.05. This shows that the Harada mori method is better at identifying fecal larvae than the direct glide method. The Kato-Katz modification method is more effective in identifying the type of worm egg than the direct slide method. The most common type of Transmitted Helminth earthworm identified in this study is hookworm. Conclusion: The Kato Katz method is a better method used than the direct slide method in identifying the type of Soil transmitted Helminth (STH) in the egg phase. Harada mori is a better method used than the direct slide method in identifying the type of Soil transmitted Helminth (STH) worm in the larval phase. The type of STH worm most identified in this study is the hookworm.

This study is to investigate experimentally fire resistance of flat slab manufactured using recycled crushed ceramics as coarse aggregate. From an economic point of view, this experiment is costly; however, if it managed and done correctly it can save raw materials, and conserve natural resources. The test is carried out on six slabs measuring 1.65*1.65*0.15m tested under flexural load exposed to fire under load for about 120 min. Two slabs were control without recycled ceramics aggregate, one slab with recycled ceramics aggregate with ratio of 35%, and three slabs with different ratios of 20%, 35% and 50% cast in layers such that the lower layer which was exposed to fire contains crushed ceramics, and the upper layer from ordinary concrete. This paper examines the feasibility of using ceramics wastes in concrete. The behavior of R.C flat slabs manufactured with recycled crushed ceramics was similar to that the normal concrete.
Curating Cartographies of Knowledge: Reading Institutional Study Abroad Portfolio as Text
Authors: Ficarra Julie M.
Published: May 2020

The professionalization of the field of Study Abroad has led to an increase in research on the student experience as well as macro-level analyses of institutional ‘best practices’ for program development and implementation. Yet what has been largely ignored is the international education epistemology embedded in the curation of what I refer to as institutional study abroad portfolios (ISAPs) - the compilation of study abroad programs focusing on specific disciplines or learning activities in particular parts of the world. In this paper, I argue that by using ISAPs as a unit of analysis we can uncover political complexity that is often obfuscated both by institution-level policy analysis as well as program-level evaluation. I present an ISAP analyses of three post-secondary institutions in the U.S. that illustrates how ‘common sense’ geographical and disciplinary pairings come to produce ‘hidden curriculum’ which results in problematic and potentially unintended cartographies of knowledge legitimization.
From Diaspora to Nationalism via Colonialism: The Jewish “Memory” Whitened, Israelized, Pinkwashed, and De-Queered
Authors: Mandour Sahar
Published: May 2020

In this essay, I argue that the concept of queerness, defined as resisting static productions of knowledge and being, constitutes a threat to the monolithic narrative of Zionist Diasporic memory. As the Jewish memories were forced into one homogeneous linear narrative, the Israeli identity was whitewashed and branded; it differentiated itself from the Arabness of Mizrahi Jews, and served to suppress the histories of migrants and Palestinians alike in favor of absolute sovereignty and settler colonialism. This process, which I call de-queering memory, debilitates cross-temporal diasporic narratives, and celebrates a pinkwashed identity of white Jewishness.
Genre et éducation sexuelle dans le système éducatif marocain
Authors: Gassim Zouhair
Published: May 2020

Le système éducatif est un lieu de socialisation par excellence. Outre sa mission de diffusion de savoir, il est un outil de transmission de normes et valeurs qui doivent régir les rapports sociaux, y compris ceux de sexes. Après une analyse genrée du contenu de l’éducation sexuelle dans les programmes scolaires marocains, force est de constater qu’il néglige/oublie l’aspect social et psycho-affectif de la sexualité contenant la dimension de genre. L’absence de ces dimensions qui sont la base de l’identité sexuelle et des représentations, contribue forcément à reproduire les systèmes de classification et de domination déjà inculqués et tatoués dans les mentalités via d’autres espaces de socialisation.
