Authors: Peng Dan , Liu Yali , Yang Jiasheng , Bi Yanlan , Chen Jingnan
Published: June 2021

The rapid and accurate detection of the moisture content is of great significance to the quality evaluation and oil extraction process of walnut kernel. Near-infrared (NIR) spectroscopy is an ideal method for measuring the moisture content in walnut kernel. In this study, a regression model for moisture content in walnut kernel was developed based on NIR diffuse reflectance spectroscopy using chemometric methods. The different spectral pretreatment methods were adopted to preprocess the original spectral data. The whole spectra band was divided into 5 subbands, 10 subbands, 15 subbands, and 20 subbands to screen specific wavelengths relevant to the walnut kernel moisture content. PLS (partial least square regression), MLR (multivariate linear regression), PCR (principle component regression), and SVR (support vector regression) were used to establish the relationship model between the spectral data and measurement values of the moisture content. In comparison, the optimized modeling conditions were determined as follows: detection wavelength 1349–1490 nm, SNV-FD (standard normal variate transformation and first derivative) preprocessing method, and PLS algorithm. Under these conditions, the square correlation coefficient (R2) and root mean square error of prediction (RMSEP) of the prediction model were 0.9865 and 0.0017, respectively. The results of this study provided a feasible method for the rapid detection of moisture content in walnut kernel. To improve the performance and applicability of the model, it is necessary to continuously expand the size of the sample set.
Recipe for Success: Suggestions and Recommendations for the Isolation and Characterisation of Bacteriocins
Authors: Twomey Ellen , Hill Colin , Field Des , Begley Máire
Published: June 2021

Bacteriocins are bacterially produced antimicrobial peptides. Although only two peptides have been approved for use as natural preservatives foods, current research is focusing on expanding their application as potential therapeutics against clinical pathogens. Our laboratory group has been working on bacteriocins for over 25 years, and during that time, we have isolated bacteriocin-producing microorganisms from a variety of sources including human skin, human faeces, and various foods. These bacteriocins were purified and characterised, and their potential applications were examined. We have also identified bioengineered derivatives of the prototype lantibiotic nisin which possess more desirable properties than the wild-type, such as enhanced antimicrobial activity. In the current communication, we discuss the main methods that were employed to identify such peptides. Furthermore, we provide a step-by-step guide to carrying out these methods that include accompanying diagrams. We hope that our recommendations and advice will be of use to others in their search for, and subsequent analysis of, novel bacteriocins, and derivatives thereof.

Published: June 2021

A robust breast cancer prevention strategy requires risk assessment biomarkers for early detection. We show that expression of ELF5, a transcription factor critical for normal mammary development, is downregulated in mammary luminal epithelia with age. DNA methylation of the ELF5 promoter is negatively correlated with expression in an age-dependent manner. Both ELF5 methylation and gene expression were used to build biological clocks to estimate chronological ages of mammary epithelia. ELF5 clock-based estimates of biological age in luminal epithelia from average-risk women were within three years of chronological age. Biological ages of breast epithelia from BRCA1 or BRCA2 mutation carriers, who were high risk for developing breast cancer, suggested they were accelerated by two decades relative to chronological age. The ELF5 DNA methylation clock had better performance at predicting biological age in luminal epithelial cells as compared with two other epigenetic clocks based on whole tissues. We propose that the changes in ELF5 expression or ELF5-proximal DNA methylation in luminal epithelia are emergent properties of at-risk breast tissue and constitute breast-specific biological clocks.

Prevention Relevance:

ELF5 expression or DNA methylation level at the ELF5 promoter region can be used as breast-specific biological clocks to identify women at higher than average risk of breast cancer.

Published: June 2021

Introduction: This study aimed to investigate the ganglion cell complex (GCC) parameters in primary angle closure suspects (PACS) and identify the related factors. Methods: A total of 731 subjects, including 289 subjects with PACS and 442 subjects without PACS, underwent RTVue XR OCT. GCC parameters were compared between the two groups. The linear mixed-effects model was performed to evaluate the relationships between the GCC parameters and related factors. Results: Significant differences were found in gender, age, spherical refractive error, height, waist, anterior chamber depth, lens thickness, axial length, superior GCC thickness, ganglion cell complex focal loss volume, ganglion cell complex global loss volume, and ganglion cell complex root mean square between PACS and normal controls. The linear mixed-effects model showed that age (p = 0.008) and blood glucose (p = 0.001) were negatively correlated with average GCC thickness in PACS subjects, and PACS (p = 0.036) and age (p < 0.001) were the key influencing factors for average GCC thickness. Conclusion: GCC parameters in PACS subjects are different from those in normal controls. Careful explanation should be considered when evaluating changes of GCC parameters in patients with PACD.

Published: June 2021

Objectives: The objectives of this study were to explore the clinical heterogeneity of differentiated thyroid cancer (DTC) between prepubertal children and adolescents and guide clinical treatment. Methods: A retrospective study included patients with DTC aged ≤19 years in Beijing Children’s Hospital from June 2014 to June 2019. All patients were enrolled and divided into 2 subgroups based on the threshold age of 10 years, namely the childhood group (CG) (≤10 years old); and the adolescent group (AG) (between 10 and 19 years old). The χ2 test and Fisher’s exact test were used to estimate the effect of risk factors in the 2 age groups. Multivariate binary logistic regression models were conducted to assess the recurrent risk factors. Results: Seventy cases of DTC were included with an average age of 9.94 ± 2.88 years, including 35 in CG and 35 in AG. The most common clinical manifestation was a painless mass in the neck, accounting for 77.1% (54/70) of patients. Compared with the AG, the CG was more likely to have lymph node metastasis (p = 0.022) and distant metastasis (p = 0.041). The CG was more likely to have extrathyroidal extension (p = 0.012) and had a significantly higher recurrence rate than the AG (p = 0.040). Age was an independent variable predictive of recurrence (p = 0.0347). Conclusion: Regional invasiveness, cervical lymph node metastasis, and distant metastasis of DTC were more likely to occur in children ≤10 years old. Meanwhile, children ≤10 years old with DTC were more likely to have recurrence than adolescent’s postsurgical treatment. Thus, children younger than 10 years of age with DTC should be treated more aggressively.

Published: June 2021

Liver abscess formation is one of the major complications following radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC). Clostridium perfringens is a rare but fatal (mortality rate: 70–100%) organism that could lead to severe sepsis. We presented a case where a 63-year-old woman with diabetes mellitus, hypertension, chronic hepatitis B-related cirrhosis in Child-Pugh class A and HCC with initial TNM stage II who had undergone 2 sessions of transarterial chemoembolization. RFA was performed for 4 small HCC due to poor effect of previous transarterial chemoembolization. However, all 4 treated tumors developed liver abscesses presenting with septic shock within 1 day. Aspirated abscesses and blood culture both yielded C. perfringens infection. After intensive care, optimal intravenous antibiotic, and abscesses aspiration, the patient recovered successfully. All tumors achieved complete response during the follow-up period without local recurrence. The clinical presentations and risk factors of C. perfringens-related liver abscess after RFA will be discussed in this manuscript.

Uma análise dos aspectos distributivos da aposentadoria por tempo de contribuição do INSS com o emprego de matemática atuarial
Authors: Afonso Luís Eduardo , Lima Daniela de Almeida
Published: June 2021

O objetivo do artigo é o cálculo de parâmetros usualmente adotados na literatura sobre previdência social, como as taxas de reposição previdenciária, alíquotas de contribuição atuarialmente justa e valores presentes de contribuições e de benefícios, para o caso brasileiro. Os cálculos são feitos para a Aposentadoria por Tempo de Contribuição (ATC) do Regime Geral de Previdência Social (RGPS) do INSS. Com tal finalidade, é construído um modelo atuarial simples para um regime previdenciário de repartição. O diferencial deste artigo em relação a trabalhos anteriores que empregavam modelos deterministas é a modelagem dos fluxos previdenciários, feita por meio de técnicas de matemática atuarial, incorporando o risco biométrico. Os cálculos são feitos para diferentes combinações de gênero, idade de início da vida laboral, renda e taxa de desconto. Os resultados mostram que as alíquotas de contribuição do RGPS, (28% a 31%), são mais do que suficientes para financiar a ATC, principalmente para os homens de renda mais elevada e que iniciaram sua vida ativa mais tarde. Os resultados fornecem evidências que as taxas de reposição (próximas a 0,5) são similares às verificadas em países desenvolvidos. Os resultados permitem três conclusões principais. A primeira é que o sistema previdenciário tem impactos distributivos intrageracionais, particularmente no tocante a gênero. A segunda é que parece ser razoável pensar em equiparação nas regras da ATC para homens e mulheres. Em terceiro lugar deve-se atentar para a influência do Fator Previdenciário sobre as questões distributivas.

Transcatheter Aortic Valve Replacement for Bicuspid Aortic Valve Stenosis: A Practical Operative Overview
Authors: Tarantini Giuseppe , Fabris Tommaso
Published: June 2021

The bicuspid aortic valve (BAV) represents a complex anatomic scenario for transcatheter aortic valve replacement (TAVR) because of its unique technical challenges. As TAVR is moving towards younger and lower-risk populations, the proportion of BAV patients undergoing TAVR is expected to rise. Initial experiences of TAVR with first-generation transcatheter heart valves in high surgical risk patients with BAV stenosis showed higher rates of device failure and periprocedural complications as compared to tricuspid anatomy. The subsequent advances in imaging techniques and understanding of BAV anatomy, new iterations of transcatheter heart valves, and growing operators’ experience yielded better outcomes. However, in the lack of randomized trials and rigorous evidence, the field of TAVR in BAV has been driven by empirical observations, with wide variability in transcatheter heart valve sizing and implantation techniques across different centers and operators. Thus, in this review article, we provide a fully illustrated overview of operative periprocedural steps for TAVR in BAV stenosis, though recognizing that it still remains anecdotal.
Cultural development of empathy-identification and empathy-modeling
Authors: Nourkova Veronika V.
Published: June 2021

Background. The article develops the concept of the originality of the functions, structure and genesis of empathy-identification (EI) and empathy-modeling (EM). EI is viewed as a psychological tool for organizing joint activities such as a mono-role coalition, which has developed in anthropogenesis, and consists in the ability to appropriate the emotional states of another person. In contrast, EM is a cultural technology for maintaining joint activity such as poly-role coordination, which requires the subject of activity to create and maintain in consciousness a dynamic representation of the mental state of another person while maintaining the authenticity of awareness of his own mental state. A consequence of the conceptual separation of EO and EM is the provision of two non-matching lines of their development in ontogenesis. Objective. The aim of the article is to explicate the qualitative uniqueness of EI and EM as higher mental functions in relation to the social situation of their development and the arsenal of ideal forms, cultural means and technologies that set the content and trajectory of this development. Design. From the standpoint of cultural-evolutionary and activity-based approaches, a conceptual analysis of literature relevant to the connotative field of the proposed constructs of EI (affective empathy, emotional contamination, emotional mimicry, imitation) and EM (theory of the mental, everyday psychology, mentalization, emotional intelligence) as well as the analysis of EI and EM constructs from the point of view of cultural determination of their development in ontogenesis was performed. Results. It has been substantiated that EI is formed in the process of dyadic joint experience with an adult of various mental states, which an adult presents first in a visual way, and then verbally. Further development of EI takes place in play activities that include imagination. EI rarely reaches the level of complete voluntary regulation and needs to rely on external cultural means. EM is derived from the dialogical nature of human thinking. In ontogeny, EM is formed along two converging lines. On the one hand, mastering the mental vocabulary serves as the basis of “emotional literacy”, and, on the other hand, EM is the result of the interiorization of a specific social and communicative position — the autonomization of an adult as a mental agent in the third person. The role-playing game with the subjective “animation” of the toy is of particular importance for the development of EM. At an older age, various forms of dramatization, in particular theatrical activity, act as cultural practices for the development of EM. Conclusions. The results of the work showed that EI and EM have different sources, driving forces, ideal forms and socio-cultural technologies of formation. The originality of the lines of cultural determination of the development of EI and EM is associated with the difference in their functional role in organizing joint activities.
Towards Comprehensive Guidance for States in the African Region to respond to Children’s Rights in Emergencies, Disasters and Pandemics
Authors: Bouah Nicole , Sloth-Nielsen Julia
Published: June 2021

The covid-19 pandemic spread has it impacted health systems, economies and communities across the African continent. It has also exacerbated risks already faced by children: limiting access to education, reducing protection from sexual and gender-based violence, harmful traditional and cultural practices including child, early or forced marriage (cefm), female genital-mutilation (fgm); and further limiting access to reproductive services and food insecurity. This article illustrates that because demonstrably different considerations arise by comparison to children’s experiences in the global north, it would be a valuable contribution for the African Committee of Experts on the Rights and Welfare of the Child to develop a General Comment on state responses to upholding children’s rights in the context of epidemics, pandemics and emergencies, tailored to the specificities of the region.
Beyond the “Epopee of Ben Guerdane”: Exploring the Plurality of Resistance at the South-Eastern Tunisian Border
Authors: Simoncini Guendalina
Published: June 2021

This article aims to shed light on the plural form of resistance performed around the South-Eastern Tunisian border area through the case study of the ordinary people of Ben Guerdane’s resistance to the jihadi attack of 7th March 2016. Placing the so-called “epopee of Ben Guerdane” in a broader historical context, it seeks to explore the fluctuations between resistance and repression along the border area both in the past and in the present, showing how multifaceted the repertoire of resistance – which includes anti-colonial struggle, guerrilla action, regime opposition, subversions, forms of everyday resistance and jihadi insurrection – has been. Following the insight of Critical Border Studies, the border will be considered as an epistemological viewpoint rather than simply a geopolitical device, considering the central role of material and symbolic borders and boundaries that shape the living experiences of Ben Guerdane’s inhabitants. The article relies on qualitative data collected during long-term fieldwork in addition to shifting the focus of the study of the Tunisian-Libyan border from national security to an approach that prioritizes the experiences of ordinary people.
I Call Center in Marocco: uno studio sulle condizioni di lavoro nel settore
Authors: Galiazzo Francesca
Published: June 2021

This article examines the main factors behind bad working conditions in the Call Centers of Morocco. The research is based on fieldwork including 15 semi-structured interviews and in the analysis of government records, labour legislation, academic studies, statistics and other reports from international organizations. The interviews were carried out in Arabic and French in 2018 in Casablanca, Rabat, Fès, Meknès and they involved workers, former workers, trade union leaders and employers from the Call Center sector. Thanks to the interviews we are able to assess in detail the issues faced by workers and, consequently, to explore them. The article highlights the fact that the bad working conditions are caused by a combination of multiple factors, such as the effects of neoliberal reforms, the economic dependence on Europe but also the inefficiency of the labour inspections.

The first part discusses the broad factors including the telecommunications’ sector reforms, international agreements, legal and tax reforms that exacerbate directly or indirectly the working conditions.

The second part aims to investigate the centers organization and other micro-factors that affect the possibility of claiming rights and speaking out against unfair practices.

In this study, Helichrysum × kani-isikii (Asteraceae), a new natural hybrid of H. compactum and H. unicapitatum from Babadağ (Denizli, Turkey), is described and investigated in detail for the first time. The new nothospecies is similar to H. compactum and H. unicapitatum, but it has some intermediate morphological and palynological properties that position it between the two putative parents. In the diagnosis of the hybrid, pollen size and shape were found as significant characteristics. Taxonomic, morphological, and palynological characteristics of H. × kani-isikii are compared with those of its putative parents, and some other details are presented with notes on the IUCN category and ecology of the nothospecies. In addition, a key to diagnosing the hybrid from its parental taxa is also provided.

Published: June 2021

During a survey of freshwater diatoms from Mojiang River, Chebaling Nature Preserve in Shaoguan City, Shixing County, Guangdong Province, China, a new Encyonema species, Encyonema chebalingense sp. nov., was discovered. Based on observations with light and scanning electron microscopy, a detailed morphological description of E. chebalingense is here presented. The main features of E. chebalingense include: conspicuously asymmetrical and dorsiventral, semielliptical to semielliptical–lanceolate valves, with a filiform raphe; dorsal margin clearly arched and ventral margin nearly straight or slightly concave; central area on the ventral side formed by 1–2 shorter central striae; and short tectullae projecting within the striae. The new species was compared with some similar species, all of which show similarities to E. chebalingense but differ in features such as dimensions, internal valve structure, stria density and valve shape. This genus is common and abundant in relatively clean waters, and other new species most likely will be recorded in the future from China.

Published: June 2021

Objective: In order to explore the clinical application effect of the upper arm venous infusion port, analyze the prevention and treatment effect of catheter rupture of the upper arm venous infusion port, and conduct a series of studies on postoperative related complications,
as well as analyze the prevention and treatment of catheter rupture of the upper arm venous infusion port effect using chest radiography and computed tomography. Methods: We collected clinical data of 98 patients implanted in the upper arm venous infusion port in the Second Affiliated
Hospital of Zhejiang University of Traditional Chinese Medicine and Hangzhou Shulan Hospital from January to December 2017, divided the 98 patients into two groups, and gave 49 patients in group A Based on the patient’s basic intervention, 49 patients in group B were given prevention
and treatment intervention of catheter rupture, and the intervention effects of the two groups were compared. Consult the nursing records during the hospitalization and maintenance period after the implantation of the upper arm vein infusion port, summarize the complications, analyze the causes,
and discuss the formulation of feasible nursing countermea-sures. Results: 98 patients were followed up for 5-16 months, with a median follow-up time of 10 months. Within 2 weeks after implantation of the upper arm vein infusion port and during discharge maintenance, the incidence of
complications was 24.49% (24/98), 8.16% (8/98), the difference in the incidence of complications between the two time periods was statistically significant (P < 0.05). Among them, common complications include incision bleeding at the port body, poor healing of the incision, local
swelling, obstruction of catheter withdrawal, extravasation of transfusion at the port body, catheter blockage, catheter displacement, and catheter-related thrombosis. There was a difference in the incidence of catheter rupture, catheter rupture time, and patient satisfaction after intervention
between the two groups of intravenous implantation patients (P < 0.05), which was statistically significant. Conclusions: Complications within 2 weeks after implantation of the upper arm venous infusion port are significantly higher than the maintenance period. Among them,
infusion extravasation, catheter-related thrombosis, catheter blockage, and catheter displacement at the port body are serious complications that directly affect the use of the upper arm infusion port . The prevention and treatment of catheter rupture for patients who have used implanted intravenous
infusion ports for a long time has significant effects, which can reduce the occurrence of catheter rupture and ensure the safety of patients’ lives and health.

Authors: Ren Kairong , Xu Xiaoxiao , Huang Pintong
Published: June 2021

Chronic hepatitis B is one of the common chronic infectious diseases in China, which seriously endangers people’s health. Liver fibrosis is a common pathological process of chronic hepatitis B. The routine diagnosis and prediction of the degree of liver fibrosis are of great value
and significance to the judgment of liver disease, clinical treatment, and the corresponding late evaluation. However, the traditional detection and treatment methods are often invasive, and the corresponding diagnosis and treatment costs are very high, which makes it difficult for the corresponding
patients in clinical and practical applications to accept, and the corresponding liver tissue samples are relatively limited in technology. In this paper, based on ultrasound elastography technology, it will give full play to its advantages of real-time, non-invasive, and repeatable detection,
and realize an effective method for non-invasive diagnosis of liver fibrosis. In the practical application, this paper mainly focuses on the study and analysis of the patients with hepatitis B liver fibrosis using the RTE ultrasonic elastic imaging technology. Following this, 120 patients
with chronic hepatitis B were selected for the experiment, and a non-invasive diagnostic model of ultrasonic elastic imaging based on a support vector machine was proposed. The experimental results showed that the diagnostic model proposed in this paper improves the diagnostic accuracy by
5% compared with the traditional diagnostic technology, while the corresponding specificity, positive predictive value, and diagnostic advantage are improved. Therefore, as a whole, the ultrasound elastic imaging model proposed in this paper could realize the efficient diagnosis of hepatitis
B liver fibrosis and is conducive to the clinical management.

Published: June 2021

Primary pulmonary lymphoma is a relatively rare extranodal lymphoma, and the incidence rate has increased in recent years. In the past, the disease mainly relied on surgery to obtain the pathological basis, so the clinical misdiagnosis rate was high. How to improve its early diagnosis
and treatment has attracted much attention. By exploring the imaging manifestations of primary pulmonary lymphoma, we can further understand and improve the imaging diagnosis level of primary pulmonary lymphoma. This paper discusses the classification, imaging manifestations, diagnosis and
identification of pulmonary lymphoma. The clinical data and imaging findings of primary pulmonary lymphoma diagnosed in a hospital were retrospectively summarized, and their imaging features were analyzed. We observe the clinicopathological characteristics and immunohistochemical phenotypes
of multiple masses with cavitation type primary lung lymphoma, and analyze the virus and imaging characteristics of hybridization. The results of the study show that the CT (Computed Tomography) manifestations of primary lung lymphoma are diverse. The characteristics of cross-leaf distribution
are more characteristic, and enhanced scanning lesions are usually mild to moderate. In the case of simultaneous masses and pneumonialike consolidation in the lungs, this disease needs to be considered.

Published: June 2021

High-resolution magnetic resonance (HRMRI) combined with magnetic resonance angiography (MRA) was used to analyze the correlation between the degree of infarction and the degree of cerebral vascular stenosis, and these patients are all have the trend to contain acute infarction. All
patients were examined by CT cerebral angiography, which was analysed by conventional magnetic resonance imaging (MRI), high-Resolution (HRMRI) imaging, and cerebral vascular (MRA) imaging. The infarct size of each patient with cerebral infarction was calculated. The degree of middle cerebral
artery stenosis was evaluated. Moreover, agnosis of acute cerebral infarction in middle cerebral artery region was calculated, and the correlation between acute cerebral infarction in middle cerebral artery region and the degree of cerebral vascular stenosis was analyzed. The specificity,
sensitivity, and accuracy of magnetic resonance angiography (MRA) in the diagnosis of acute cerebral infarction in the blood supply area of the middle cerebral artery were 90.48%, 94.87%, and 93.94%. The coincidence rates for the degree of middle cerebral artery stenosis were 90.91% for mild
stenosis, 92.31% for moderate stenosis, 93.75% for severe stenosis, and 85.71% for vascular occlusion, respectively. The K value was in good agreement with the results of CTA diagnosis (≥0.75). In conclusion, HRMRI can clearly indicated that the location of lesions with acute cerebral
infarction, and MRA can show the degree of vascular stenosis, there is a close relationship between them.

Authors: Meijers Sebastiaan , Meijers Rutger , van der Veen Erwin , van den Aardweg Maaike , Bruijnzeel Hanneke
Published: June 2021

Objective:

During the last 2 decades, new treatment methods have been developed for the surgical removal of second branchial cysts which result in less visible scars. The aim of this systematic review is to assess which surgical technique for second branchial arch cyst removal results in the lowest complication and recurrence rates with the highest scar satisfaction.

Methods:

Two authors systematically reviewed the literature in the Cochrane, PubMed, and EMBASE databases (search date: 1975 to December 2nd, 2020) to identify studies comparing surgical outcomes of second branchial arch cyst removal. Authors appraised selected studies on directness of evidence and risk of bias. Results are reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

Results:

Out of the 2442 retrieved articles, 4 articles were included in the current review including a total of 140 operated cysts. Only 2 studies included pre-operatively infected cysts. Follow up ranged from 3 to 24 months. Complication rates ranged from 0 to 27.3% (conventional: [0–10.4%]; endoscopic/retro-auricular: [0–27.3%]). None of the patients presented with postoperative recurrence. Significantly higher scar satisfaction was found in adult patients who underwent endoscopic or retro-auricular hairline incision cyst removal.

Conclusion:

No recurrence of disease occurred during (at least) 3 months of follow up using either conventional surgery or endoscopic/retro-auricular techniques. Although more (temporary) complications occur using endoscopic and retro-auricular techniques, patients report a significantly higher scar satisfaction 3 to 6 months after surgery in comparison to the conventional technique. Future studies are needed to support these findings.

Authors: Agarwalla Shradha , Saha Debolina
Published: June 2021

The forest as an ecosystem plays a vital role in protecting the environment and meeting indispensable human needs. Restrictions on forestry activities for safeguarding the environment and seasonality in collection often count for vulnerable livelihood of the forest-fringe dwellers. This paper is an attempt to assess the existing opportunities for livelihood diversification of the forest dwellers residing at the Simlipal National Park region, India, through the Herfindahl–Hirschman Index; and to determine the key factors responsible for the scopes and realization of livelihood diversification through econometric modeling. The analysis is done across blocks with having different forest-zonal geographies and human characteristics to comprehend and ensure sustainable livelihood for a better future.

In Morocco, the adoption of recent improved wheat varieties is low, casting doubt on whether investments in wheat research are paying off. This paper generates estimates of the returns to the national and international investment in wheat research for Morocco. The benefits are estimated by applying the endogenous switching regression model to data from a nationally representative sample survey of 2,296 wheat fields, whereas costs were estimated using data on public and CGIAR (INRA-CG) investments on wheat research in Morocco. Considering all the benefits and costs of wheat research investment in Morocco, we estimated a conservative benefit-cost ratio (BCR) of 19.64 with 623 thousand tons (14.8%) of additional wheat supply from domestic production and net economic benefit of US$355 million. We also estimated that institutional problems in the seed system identified by past research are causing the country to lose at least 746.6 thousand tons (17.7%) wheat production and net economic benefit of US$75.2 million. These results show that despite the institutional challenges, wheat research in Morocco is still paying off and the country has sufficient incentives to address the problems in the seed sector that prevent the development and uptake of recent varieties.
Examining the Moderator Role of Sleep Quality in the Relationship Among Test Anxiety, Academic Success and Mood
Authors: Adams Sue K , Mushkat Zoe , Minkel Jared
Published: June 2021

This study explored associations among test anxiety, GPA, sleep quality, and mood in college students. Data were collected from undergraduate students ( N = 316). Results revealed that higher levels of test anxiety and sleep impairment predicted negative mood in undergraduates. Findings suggest that prioritizing sleep could help improve overall mood among students with test anxiety. Future studies should work toward clarifying the complex and reciprocal relationship between sleep and test anxiety.
Feminist Solidarities and Coalitional Identity: The Popular Feminism of the Marcha das Margaridas
Authors: Motta Renata
Published: June 2021

The Marcha das Margaridas is a mass mobilization in Brazil led by women’s organizations within rural unions in alliance with other social movements and nongovernmental organizations, including transnational partners such as the World March of Women. The main political subjects are rural working women, a political identity that articulates gender, class, and urban-rural inequalities. These are foundational for the popular feminism of the Marcha. An examination of the Marcha das Margaridas guided by a theoretical discussion of poststructural feminism and postcolonial feminism on the role of political identities in building coalitions reveals that it expands the agenda of popular feminism in its relationship to historical feminist agendas and intersectional feminisms and in its coalition politics with men and the left.

A Marcha das Margaridas é uma mobilização de massa no Brasil liderada por organismos de mulheres dentro de sindicatos rurais em aliança com outros movimentos sociais e organizações não governamentais (ONGs), incluindo parceiros transnacionais como a Marcha Mundial das Mulheres. Os principais sujeitos políticos são as mulheres trabalhadoras rurais, uma identidade política que articula as desigualdades de gênero, classe e urbano-rurais. Estes são fundamentais para o feminismo popular da Marcha. Um estudo da Marcha das Margaridas guiado por uma discussão teórica do feminismo pós-estrutural e do feminismo pós-colonial sobre o papel das identidades políticas na construção de coalizões revela que ela expande a agenda do feminismo popular em sua relação com agendas feministas históricas e feminismos intersetoriais, como também em sua coalizão política com os homens e a esquerda.
Retail Suburbanization, Modernization, and Growth in Sydney during Australia’s Postwar Boom
Authors: Bailey Matthew
Published: June 2021

This article uses Sydney as a case study to examine the process of retail decentralization during Australia’s postwar boom, showing how the form and function of capital city retailing changed completely in just a couple of decades. Suburban migration, the emergence of mobile car-driving consumers, socially constructed gender roles, the ongoing importance of public transport networks, planning regimes that sought to concentrate development in designated zones, and business growth strategies that deployed retail formats developed in America all played a role in shaping the form and function of Australian retailing during the postwar boom. In the process, the retail geographies of Australia’s capital cities were transformed from highly centralized distribution structures dominated by the urban core, to decentralized landscapes of retail clusters featuring modern retail forms like the supermarket and shopping center that would come to define Australian retailing for the remainder of the century.
Decoupling gender equality from gender pay audits in Swedish municipalities
Authors: Salminen-Karlsson Minna , Fogelberg Eriksson Anna
Published: June 2021

This article investigates processes of gender pay audits in five municipalities in Sweden in order to understand the reasons why gender pay audits in general do not level out men’s and women’s salaries in the way they are intended to. The results show how gender pay audits became a bureaucratic process to fulfil a legal requirement, and how they were decoupled from core organizational practices and salary policies. This decoupling was furthered by the realization that the result of gender pay audits would imply a need for large structural changes in pay policies, for which there were no financial means. Consequently, decoupling was found to be a major reason why gender pay audits are ineffective in coming to terms with gender pay gaps.
Functional Olfactory Neuroblastoma Inducing Symptomatic SIADH
Authors: Heiland Luke , Heiland Kurt
Published: June 2021

Olfactory neuroblastoma (ONB) is a rare malignancy of the sinonasal cavity, originating from neuroepithelial olfactory cells. Olfactory neuroblastoma can be difficult to diagnose due to its anatomic position and variable symptomatic presentation, leading to diagnosis at a more advanced stage. Here, we present the case of a 35-year-old man with no previous medical history who had a bicycle accident secondary to syncope. He was found to be hyponatremic and suspected to have syndrome of inappropriate antidiuretic hormone secretion (SIADH). In the workup of SIADH, a brain magnetic resonance imaging revealed a mass in the left middle meatus. The lesion secreted inappropriate amounts of ADH, resulting in symptomatic paraneoplastic SIADH. This ultimately led to the early recognition and successful resection of this rare ONB. The patient has remained disease-free for over 5 years. This case is a fortunate example of a functional malignancy of the sinonasal tract that was discovered early and successfully treated as a result of symptomatic SIADH.
A Comparative Case Study Analysis of Barriers and Facilitators to Implementing the Affordable Care Act’s Balancing Incentive Program
Authors: Beauregard Lisa Kalimon , Miller Edward Alan
Published: June 2021

The Affordable Care Act included the opportunity for states to increase spending on Medicaid home and community-based services (HCBS) for older adults and persons with disabilities through the Balancing Incentive Program (BIP). This study utilized comparative case studies to identify the factors that facilitated or impeded states’ implementation of BIP. Findings indicate factors that facilitated the implementation of BIP were communication with the federal government and its contractor, merging BIP with existing HCBS programs, and enhanced federal revenue. On the other hand, the short duration of BIP, state procurement and contracting processes, and the need to incorporate feedback from non-governmental stakeholders and determining how to spend the enhanced revenue proved challenging for some states. This research suggests ways federal and state officials can implement new initiatives to achieve greater rebalancing of Medicaid long-term services and supports for older adults.
De-staging the people: On the role of the social and populism beyond politics
Authors: Feinberg Joseph Grim
Published: June 2021

This paper engages with radical democratic theory in light of the so-called ‘return of the people’ taking place in contemporary political discourse. I argue that the return of the people should not be seen only as a return of politics strictly speaking, but also as a process by which elements of the social that had previously been excluded from politics enter the political sphere. Framing the problem in this way calls for a view to how politics is circumscribed, distinguished from the social but also, at various moments, broken open. At the same time, I call for paying increased attention to how the notion of the people takes shape beyond the political sphere, off the metaphorical political stage. By examining how the people is constructed in cultural and social movements, off the political stage, we can better understand the form taken by the people when it appears in politics.
