Authors: Raudina Farisa , Hidayat Yudi Mulyana , Rachmayati Sylvia
Published: January 2021

Background: The incidence of gestational trophoblastic neoplasia (GTN) is high in Indonesia. Based on the FIGO prognostic score, GTN is classified into low-risk and high-risk categories. The high-risk group requires multidrug chemotherapy whereas the low-risk group requires single-drug chemotherapy. Response to chemotherapy would reflect the remission rate. The aim of this study was to describe the response to chemotherapy in GTN patients Methods: This was a cross-sectional descriptive retrospective study on medical records of patients with GTN treated in Dr. Hasan Sadikin General Hospital during the period of 2016 to 2018. The inclusion criteria were GTN patients who received > 3 cycles of chemotherapy while the exclusion criteria were incomplete, inaccessible, or missing data. Data were collected on patient’s age, parity, history of previous pregnancy, pregnancy-therapy interval, tumor size, number and location of metastases, and history of failed chemotherapy. Results: Of the189 medical records of the GTN patient collected, only 88 met the inclusion criteria, (63.6% low risk and 36.4% high risk). Most patients were responsive to chemotherapy (61.4%), aged<40 years old, multiparity, tumor size >5 cm, had 4 month interval from previous pregnancy <4 months, had a history of molar pregnancy, had no metastases, and no previous failed chemotherapy. Conclusion: The chemotherapy response in gestational trophoblastic neoplasm patients is fairly good with most patients are in the low-risk groups. Specific tumor markers used in early diagnosis of GTN may play a major role.

Published: January 2021

Background: Traditional health service is one of the health services that is still currently used in Indonesia, especially in rural communities. The government has been regulating these services since 2014. Despite its long existence, there is a recent increase of potential regulation violation among traditional health service providers. This study aimed to explore the perspective of the Cikahuripan Villagers on Government Regulation on traditional health services. Methods: This was a qualitative study using in-depth interviews and direct observations on traditional health services in Cikahuripan Village. Sixteen informants consisting of 8 villagers who met the inclusion criteria and another 8 informants in the triangulation negative case analysis, member checking, peer debriefing, and observation was involved. Results: There were two different perspectives in the community on traditional health service provisions in the Government Regulation. Supporters of the regulation believed that the regulation would make traditional health services more responsive and safer, which would improve service quality and health benefits as well as imposing effective sanctions. In contrast, the opposition believed that regulations were too late, would make the costs for licensing expensive, and too complicated. Conclusion: There are two different public perspectives on the regulation of traditional health services, which are supporting and opposing the regulation. It is expected that the local government create a derivative of the regulation by making adjustment to the community’s situation.

Published: January 2021

The development of technology and information demands elementary school teachers to be able to make and teach technology-based musical instruments so that the development of technology and information can be used in the learning process. Elementary school teachers also have problems teaching musical composition using ensemble musical instruments. Teachers also lack strategies and media to teach musical instruments, so they need to have ideas for developing technology-based musical instruments. This study aims to develop the elementary school teachers’ ability to innovate and make music learning media using a computerized system. The research design used was action research. The participants were 38 teachers from nine regencies and cities in West Java, Indonesia. The results showed that the teachers were able to complete the task of making technology-based learning media which means that they were able to develop their technological abilities to make music learning media. Teachers can easily use and master the Scratch application to make music learning media. It can be concluded that with structured and controlled training, elementary school teachers can develop themselves and innovate well.
Crooked Views and Relaxed Rules: How Teenage Boys Experience Parents’ Handling of Digital Gaming
Authors: Meriläinen Mikko
Published: January 2021

Digital gaming is a major part of the current media landscape. Parents employ a variety of practices, such as limiting gaming time and discussing games, when addressing their childrens’ gaming. Yet, there is still a notable gaming-related generational gap between adolescents and their parents. In this qualitative study, gaming-related parenting practices and parents’ and teenagers’ views are examined through a thematic analysis of reports from Finnish, 16–19-year-old, active game players. The results suggest a core tension between elements of protection and understanding. Perceived parental attitudes towards gaming ranged from excessively negative to indifferent to very positive. These attitudes were not static, but instead changed according to life situations and parents’ familiarity with gaming. Young game players’ perceptions and views were also not uniform. Respondents indicated the need for both parental understanding of games and gaming, and parents’ responsibilities in limiting gaming, particularly in the case of younger children. Implications for parenting and future research are discussed.

Danio reriohas firmly established itself as a successful model for research in many areas of biology and medicine, first of all for developing new medicines.

The aimof our study was to evaluate ghrelin level in zebrafish brain after stress and after phenazepam usage on stressed fish.

Methods.In our study 96Danio rerio, predatorCichlasoma nicaraguensishave been used. The fish have been kept at anormal room temperature (2223C) with standard feeding time (twice per day). The level of neuropeptides has been tested by ELISA test. During experiment a fish has been firstly placed in a beaker with a dissolved pharmacological substance, then has been transferred into a tank with predator. In the end of experiment, it has been put into a novel tank for 6 min. The decapitation has been made. Thebrain has been divided into three anatomical parts:telencephalonjust behind the olfactory bulb, the middle partcorpora bigemiaandcerebellum, which is situated behind thecorpora bigemia. After that the material for ELISA test was made using GhrelinFISH, MyBioSource ELISA kit.

Results.In the control group ghrelin has been determined only in thecerebellumin 57.14% of all fish. In the experiment with predator ghrelin has been found in all tested brain parts of fish, but in thetelencephalonthere was the highest level. Inthe experiment with phenazepam usage only and phenazepam administration after predator stress, the ghrelin value has not been determined atall.

Conclusion.Thus we have found out that the ghrelin value increases after predator stress and the drug phenazepam eliminated it completely after its administration. We may suppose that the administration of anxiolytics such as phenazepam can reduce the anxiety inDanio rerio.

Association of Obstructive Sleep Apnea Indicators with Heart Failure
Authors: Handoo Faheem , Liu Yuyao , Schütz Sonja G. , Chervin Ronald D. , Dinov Ivo D.
Published: January 2021

Background: Obstructive sleep apnea (OSA) occurs when the airway is repeatedly blocked during sleep, resulting in frequent brief awakenings throughout the night. OSA has been found to increase the risk of many cardiovascular diseases, especially heart failure (HF). HF with reduced, preserved, and borderline ejection fraction (HFrEF, HFpEF, and HFbEF) are three subtypes common in OSA patients. The aim of this study is to further explore the relationship between OSA and HF and the influence of specific OSA measures.
Methods: Electronic medical data was collected from health histories, echocardiograms, and polysomnography studies. Observations were sorted into three categories based on left ventricular ejection fraction: HFpEF (n=334), HFrEF (n=77), and HFbEF (n=37). Multinomial logistic regression was then conducted to determine the relative risk of HFpEF and HFrEF from each variable as compared to the baseline HFbEF.
Results: Pacemaker presence, previous stroke, BMI, and a measure of left ventricular dysfunction (LVD), called relative wall thickness, all raised the risk of HFpEF compared to HFbEF, while another LVD measure, left ventricular end-systolic dimension, reduced it. These factors also increased risk for HFrEF, except for previous stroke and pacemaker presence, which were not significant. Relevant OSA metrices included average blood oxygen saturation and three measures of sleep apnea severity, named central apnea index, hypopnea index per hour, and the Epworth Sleepiness Scale (ESS). These all decreased relative HFpEF risk, other than ESS, which raised it.
Conclusions: As was expected, several standard HF predictors increased the risk of both types of HF. Surprisingly, few OSA indices had the same effect. This suggests that targeting specific OSA markers may not be effective in treating patients with any of these HF types. Future work could involve the influence of OSA and its indices on mortality, or the responses of these indicators to treatment, both topics with limited previous findings.
LEARNER – CONTENT INTERACTION IN AN ONLINE ENGLISH LANGUAGE LEARNING COURSE IN VIETNAM
Authors: Pham Ngoc Thach , Tran Minh Thanh
Published: January 2021

Interaction plays a critical role in both traditional and online learning processes. For online learners of English, interaction with course content is especially vital because it provides them with necessary knowledge in language competence and contributes to success of online learning. This paper presents the findings of a study about learner-content interaction in an online English learning course implemented at a university in Vietnam. The study findings reveal that the learners’ online time-on-task, average grades and test scores decreased as the units went. There was a correlation among these three variables, but the online learning grades and tests did not predict offline study results. The study recommends a stronger integration between online and offline learning (blended) for overall success in language learning
Integrated Fault Evaluation Through Fusion Algorithm Supported by Kalman Filter
Authors: Mousavi Sadra , Kara Duygu Bayram , Seker Sahin Serhat
Published: January 2021

An Integrated Fault Evaluation (IFE) process is proposed in this study. It includes Sensor Validation (SV), Fault Detection (FD) and Fault Source Identification (FSI). The proposed algorithm employs data fusion algorithm enhanced by Kalman filter (KF). As the case study, vibration signals representing different aging states of an induction motor are used. The vibration data collected from two identical sensors with different measurement and process noises are achieved. Through the statistical and frequency domain characteristics, IFE is realized. The most prominent contribution of the study is the capability of distinction between the aging of the system and the process problems. For this aim, a rate representing the healthiness, which can discern the impact of the process noise and system aging, is calculated.
Preictal and Interictal Recognition for Epileptic Seizure Prediction Using Pre-trained 2D-CNN Models
Authors: Toraman Suat
Published: January 2021

Epilepsy is a neurological disease affecting almost 1% of world population. Predicting a possible seizure will make a significant contribution to improving the quality of life of patients suffering from this disease. One of the most important steps in seizure prediction studies is the preictal activity recognition stage. In many previous studies, the preictal state was determined to end at the onset of the seizure, which makes it difficult for the physician to intervene in the patient in a possible seizure. In the proposed method, unlike previous studies, the preictal state was determined as the 30-minute interval ending 30 minutes before the onset of an epileptic seizure. The method consisted of three stages; (I) preictal and interictal activities were divided into five-second segments, (ii) the separated signals were converted into spectrograms, and (iii) the spectrogram images were classified using three different pre-trained CNN models (VGG19, ResNet, DenseNet) and the results were compared among these models. Classification was performed separately using the predetermined four EEG channels for 20 cases in the CHB-MIT dataset. The best classification accuracy value in preictal/interictal discrimination (91.05%) was obtained on channel 8 (P3-O1). An important contribution of this study was that the proposed approach provided important information about the preictal and interictal discrimination of the section 30 minutes before the onset of seizures. In addition, by examining the four channels separately, channel-based information on preictal/interictal discrimination was also obtained. Based on these results, we consider that the proposed method will bring a different perspective to seizure prediction studies.

Published: January 2021

With the increasingly serious aging trend in China, the incidence of some chronic diseasesrelated to it is also increasing. In this regard, the demands of elderly care gradually show a trend of diversified development, and the requirements of nursing quality become more and more strict. In China, most nursing personnel training is accomplished through colleges and universities, many of which come from the nursing profession. However, there is no division of nursing disciplinesfor elderly patients at present, and the corresponding training plan, content and target for elderly care are not specific. Next, we focus on the implementation strategy of training elderly nursing talents based on the needs of elderly care.
An Evaluation of Cripps’ Population-Tied Schemes

Published: January 2021

As the world population reaches 7.8 billion in 2020, humanity’s ecological footprint has become one of major global concerns. In this essay, I will explain population-tied schemes for distributing costs to reduce the global ecological footprint as found in Cripps’s paper and discuss the issues related to them. I shall argue that a universal population-tied scheme is not morally defensible at the current stage, while a ‘tailored’ population-tied scheme with modifications is morally defensible.

Application of Polypropylene Mesh Implants in Thoracic Surgery
Authors: Belov Sergei , Grigoryuk Alexander
Published: January 2021

The widespread introduction of synthetic grafts into the clinical practice became possible after recent advances in fundamental sciences and production technologies. Now implants are in common use in angiosurgery, orthopedics, gynecology, abdominal and thoracic surgery. Most often, synthetic materials are used in mesh prostheses. The results of literature review demonstrate rapid development and advances of the polypropylene mesh implant techniques in thoracic surgery. The authors highlight the application of polypropylene mesh in the reconstruction of the chest wall, the creation of lung compression, closing the diaphragm defect. The main reason for mesh transplant use in thoracic surgery is an increase in the effectiveness of surgical treatment methods, elimination of the mechanism of respiratory problems and associated complications. The study of the biological properties of mesh implants and reparative processes can considerably expand opportunities and prospects for their further application in thoracic surgery, both in resection and plastic directions, and during collapse surgery. Combinations of various types of synthetic materials provide not only mechanical support in chest surgery, but also ensure good functional results of the organs.
Surgery Techniques for Urgent Intestinal Neostomy and Bypass
Authors: Sizov Mihail , Romanov Ivan , Vorob'yov Aleksandr , Semyonov Andrej
Published: January 2021

Introduction. Modern standards for the treatment of acute abdominal surgical diseases suggest a temporary exclusion of the impaired intestinal part from the digestion. This reduces the morbidity of the primary operation, but also results in specific postoperative complications.The aim of the study was to analyze current data on the technique and effectiveness of urgent intestinal neostomy and bypass surgery.Results. The authors analyzed 39 modern literature sources that deal with the problem of urgent intestinal neostomy and bypass surgery. Currently, there is a growing interest in developing techniques for early (before anastomosis) restoration of the chyme passage across the intestine bypassing the impaired intestinal area. It has been reported that a number of unresolved issues do not yet allow full implementation of the concept of intestinal bypass (shunt): a safe mechanism for performing an anastomosis between the small intestine and a synthetic prosthesis has not been developed, the problem of creating unidirectional pathway along a non-peristaltic intestinal prosthesis has not been solved.Conclusion. Solution of these problems can contribute to a significant improvement in the clinical outcomes of patients with acute ischemic or traumatic damage to the intestine.

Published: January 2021

O presente trabalho é parte de uma dissertação de mestrado e tem por objetivo aproximar a modelagem matemática na perspectiva sociocrítica da teoria dos registros de representação semiótica analisando a formação do conceito do número racional. A situação extraída do contexto sociocultural dos alunos foi a problemática da escassez de água cuja questão desafiadora foi: eu sou gastão de água? que consistia em medir o próprio consumo de água por um dia. O objeto matemático que surgiu dessa investigação foi o número racional. Trata-se de uma pesquisa qualitativa, desenvolvida numa escola pública, com alunos do 8º ano do ensino fundamental. As análises revelam que a modelagem na perspectiva sociocrítica foi terreno fecundo para um trabalho pedagógico que considera a diversidade de registros usados na educação matemática. A partir dos dados oriundos da medição da água os alunos foram estimulados a fazerem transformações de conversão, favorecendo a aprendizagem do conceito de número racional.

Published: January 2021

O objetivo desta pesquisa foi identificar concepções que perpassam as imagens de microrganismos, disponibilizadas on-line, avaliando se estas contribuem para a construção adequada, reducionista ou equivocada do ensino em microbiologia. O estudo, de caráter qualitativo, orientou-se pelo enfoque exploratório, utilizando como metodologia a construção de um banco de imagens selecionadas por meio da ferramenta Google Imagens de pesquisa na web. Foram analisadas 1421 imagens agrupadas pelas palavras-chave: “microrganismos” e “micro-organismos”, originando onze categorias de análise. Os resultados indicam que nas imagens on-line os microrganismos são lembrados por sua nocividade para a saúde humana. Em contrapartida, revelam uma escassez de recursos imagéticos no que tange aos benefícios proporcionados pelos microrganismos. Tal resultado contribui para uma concepção equivocada, cabendo ao professor utilizar as imagens de forma crítica e responsável.
Controvérsias sociocientíficas: análise comparativa entre Brasil e Portugal
Authors: Krupczak Carla , Aires Joanez Aparecida , Reis Pedro Guilherme Rocha dos
Published: January 2021

A discussão de controvérsias sociocientíficas é uma das estratégias didáticas que podem estimular o desenvolvimento da alfabetização científica. Mas, essa abordagem é utilizada da mesma forma e com os mesmos objetivos em diferentes contextos educacionais? Pensando nisto, este trabalho tem como objetivo analisar como as controvérsias sociocientíficas são abordadas nas pesquisas brasileiras e portuguesas, buscando identificar as semelhanças e diferenças dos dois contextos educacionais e de pesquisa. Os dados foram constituídos no Brasil e em Portugal, a partir do Catálogo de Teses e Dissertações da CAPES e do site do repositório do Instituto de Educação da Universidade de Lisboa, respectivamente. Os resultados mostram que os pesquisadores portugueses usam a discussão de controvérsias sociocientíficas, sobretudo, para desenvolver competências para a cidadania e ativismo. Já as investigações brasileiras têm como objetivo, principalmente, a aprendizagem dos conteúdos científicos. Isto pode estar relacionado com a menor qualidade da educação básica brasileira, por vários motivos, que vão desde as lacunas na formação dos professores até a pouca valorização da profissão docente.
Uma leitura arqueogenealógica do racismo estrutural em instituições do sistema de justiça do Maranhão
Authors: Da Silva Junior Francisco Carlos , Cruz Mônica Da Silva
Published: January 2021

Neste artigo, apoiados no método arqueogenealógico proposto por Michel Foucault (2010), segundo o qual as relações de poder são constitutivas de toda prática (não) discursiva, apresentamos algumas reflexões sobre o racismo estrutural presente em decisões do poder Judiciário do Maranhão, estado onde existe uma das maiores populações negras do país. A pergunta que buscamos responder é: a negação do racismo fomenta o racismo estrutural em redes discursivas da justiça no Maranhão? O corpus se constitui de um processo coletado no Sistema de Justiça do Maranhão (https://jurisconsult.tjma.jus.br/#/home), processo nº 5911682015, que tramitou na 5º Vara Criminal do Fórum da Comarca de São Luís. Os resultados demonstram que a negação do racismo pavimenta práticas de impunidade em instituições do sistema de justiça maranhenses.

Published: January 2021

Este artigo objetiva cartografar práticas discursivas, materializadas nos cartazes e faixas das manifestações de rua ocorridas no Brasil (2019-2020). A rua é o palco de produção de subjetividades. Nossa análise, baseada no referencial teórico dos Estudos Discursivos Foucaultianos, utiliza as noções de enunciado, sujeito, dispositivo, corpo, poder, biopolítica, governamentalidade, dentre outras. Esta cartografia espacial, feita à luz de uma arqueogenealogia, tem como fim, não apenas discutir as relações de poder por meio do inventário de técnicas e táticas discursivas, nem somente mapear produções de subjetividade para descrever/analisar como somos e por que somos assim, mas sobretudo diagnosticar o tempo presente com a problematização do funcionamento do território urbano para recusarmos o que nos é imposto e apontarmos possibilidades de sermos diferentes.
50 anos de Arqueologia do Saber: as contribuições aos estudos da linguagem no Brasil

Michel Foucault, sem dúvida, representa um dos mais influentes intelectuais do século XXI. Embora tenha falecido em 1984, sua obra, como assinala Deleuze, nos deixou uma significativa caixa de ferramentas teórica, que ajuda a problematizar a verdade e a verticalizar a história do presente. Lido pelas mais diferentes áreas do conhecimento, seus livros, seus ditos e escritos extrapolaram as fronteiras disciplinares. Um dos aspectos importantes das análises de Michel Foucault sobre as condições de possibilidade do discurso é o modo como ele traz para suas análises a ideia de que o discurso é acontecimento, o que impõe que se recusem temas como origem, causalidade, espírito de época, por exemplo. A noção de acontecimento devolve aos discursos o seu caráter de irrupção, ao mesmo tempo em que sinaliza para uma fratura no arquivo.Foucault propôs um tipo de história diferente daquela que privilegiava os grandes sujeitos, a chamada macro-história. Deixou de olhar para as grandes batalhas, as importantes lutas de monarcas, para se voltar para os pequenos acontecimentos (a micro-história), que fazem a história mudar seu curso. História não mais reduzida ou referida a um desejo totalizante de um sujeito originário, mas história que se faz entre as relações discursivas, que coloca o sujeito não como centro, mas como disperso nas posições discursivas que assume no discurso.No ano de 2019, comemoramos os 50 anos da publicação de “A Arqueologia do Saber”, leitura fundamental para pesquisadores, professores e estudantes interessados nos estudos do discurso com Michel Foucault no Brasil. Neste livro, o autor se posiciona criticamente diante de um projeto positivista de história tradicional por meio de uma série de oposições. Assim, contrapondo-se a uma história que se desenvolve em uma continuidade linear e simples, o autor, fundamentado em Nietzsche, Bachelard e Canguilhem, propõe uma genealogia cujo motor é a descontinuidade.
Nomes de bairros de São Luís do Maranhão: o que revelam os topônimos oriundos de algumas siglas institucionais?

O presente artigo investiga os nomes de bairros da Capital do Maranhão, São Luís, especificamente, aqueles surgidos a partir de siglas institucionais, isto é, siglas de institutos e/ou cooperativas que financiavam moradias para a sociedade civil ou a seus associados. Convém aclararmos que esse é um traço bastante característico do processo habitacional de São Luís, justificando assim nosso estudo. Dessa forma, analisamos os nomes de três bairros: Cohatrac I, Ipase e Ipem Turu. Esses topônimos são uma mostra de siglas que se ressemantizaram, isto é, adquiriram outros significados. Portanto, descrevemos o léxico toponímico dos três bairros da capital do Maranhão, detalhando de que forma eles documentam o processo habitacional da Cidade. O aporte teórico que sustenta nossa pesquisa está pautado em estudos de Dick (1990) e Curvelo (2009). Os resultados preliminares nos mostram que os topônimos Cohatrac I, Ipase e Ipem Turu documentam não só aspectos antropoculturais, mas físicos.
AVALIAÇÃO DA DISTRIBUIÇÃO ESPACIAL DA MALÁRIA E DA LEISHMANIOSE TEGUMENTAR NO MUNICÍPIO DE TOMÉ-AÇU/PA
Authors: Nunes Raquel Soares Casaes , Casaes Roberta Soares
Published: January 2021

O município de Tomé-Açu/PA possui desenvolvimento voltado para a agricultura, mas em decorrência do desmatamento e do crescimento da cidade, a população tornou-se suscetível ao contato com vetores de Doenças Infecciosas e Parasitárias (DIPs). Em virtude das insuficientes informações sobre a distribuição espacial da ocorrência de DIPs na mesorregião do nordeste paraense e da possibilidade de novas informações que contribuam para a gestão ambiental dos municípios, busca-se através deste trabalho mapear a distribuição espacial de 2008 e 2018 sobre os casos registrados no município. Trata-se, portanto, de uma pesquisa quantitativa e qualitativa que correlaciona as DIPs Leishmaniose Tegumentar e Malária como desflorestamento. Os dados foram obtidos na Secretária de Saúde do município para a obtenção dos locais de ocorrência das doenças. Após o procedimento de importação dos dados, foram aplicados o estimador de Densidade de Kernel e o Índice Global de Moran para gerar mapas de 2008 e 2018 que evidenciam as diferentes densidades dos fenômenos e as áreas de maior risco epidemiológico, onde o uso e ocupação do solo são fatores predominantes para a epidemia de DIPs na região devido à ocupação humana nas proximidades de áreas recém-desflorestadas. De acordo com os números de casos registrados, a Leishmaniose Tegumentar foi a doença com maior incidência nos anos de 2008 e 2018. No entanto, a Malária teve um predomínio na área rural em 2008. Conclui-se que a metodologia utilizada pode contribuir para entendimento de onde devem ser intensificadas ações de vigilância e controle para a saúde da população.
How the Year of a Thousand Unknowns Could Transform Camp
Authors: Rogge Ariella
Published: January 2021

COVID-19 made many summer camp professionals cancel their 2020 programs. Summer camp professionals who cancelled, or significantly modified their programs, still have something to do: they have an opportunity to change. In the applied research environment, this new body of information will be fascinating to examine as it could potentially help all camps embrace the value of certain strategies, messaging and crisis management concepts to improve relationships and broaden the value of the camp experience.
discourse of dependency and the agrarian roots of welfare doctrines in Africa: The case of Botswana
Authors: Seekings Jeremy
Published: January 2021

Political elites across much of Africa have criticized welfare programmes and the idea of a welfare state for fostering dependency. Anxiety over dependency is not unique to East or Southern Africa, but the discourse of dependency in countries such as Botswana differs in important respects to the discourses of dependency articulated in some industrialised societies (notably the USA). This paper examines African discourses of dependency through a case-study of Botswana. The paper races the genealogy of dependency through programmatic responses to drought between the 1960s and 1990s, and a reaction in the 2000s. The growth of a discourse of dependency reflected both social and economic concerns: Socially, it was rooted in pre-existing understandings of the reciprocal responsibilities associated with kinship and community; economically, the emergence of a discourse of dependency reflected the rise of an approach to development rooted in nostalgic conceptions of hard-working small farmers. The discourse of dependency appealed to both conservatives (offended by anti-social individualism) and economic modernisers (eager for an explanation for the failures of the developmental project to eliminate poverty).
Varieties and drivers of social welfare in sub-Saharan Africa: A critical assessment of current research
Authors: Künzler Daniel , Nollert Michael
Published: January 2021

How can we conceptually grasp social policies on the macro level in sub-Saharan Africa? Decommodification and defamilialisation, two key concepts of Esping-Andersen’s seminal typology, are not very helpful to distinguish welfare regimes in sub-Saharan Africa. Moreover, typologies that have been developed for the Global South hardly consider social stratification. In conclusion, there is no typology including African states that covers all relevant dimensions of welfare and includes education, agricultural, and housing policies. There is also more need for compara-tive research on the drivers of social policies and especially policies that are more likely to reduce inequality.
