{"title":"Evidence to Inform Resilience Policy in the SADC: Current Limitations and Future Research Areas","authors":"O. Pretorius, J. Drewes, T. Gumbo","doi":"10.3390/world3030024","DOIUrl":"https://doi.org/10.3390/world3030024","url":null,"abstract":"The Southern African Development Community (SADC) and its member countries are potentially vulnerable to external disturbances, including environmental, economic, and social shocks. Regional policy emphasizes interventions to ensure long-term growth and development in the face of potential disturbance. Current emphasis is placed on mitigating the impact of climate change, including the creation of the SADC Climate Change Strategy and Action Plan. However, the need for long-term adaptation and associated policy is evident to reduce regional vulnerabilities. Research is an important source of evidence to support policymaking, with specific importance to institutions in developing regions such as the SADC and during times of global change and disruption. SADC development policy related to resilience outcomes ought to be informed by research. This paper investigates the extent to which existing research supports regional resilience policymaking. Objectives include investigating available research on resilience in the SADC, identifying potential limitations, and delineating areas of future research to be considered by researchers that contribute to knowledge and evidence creation. A bibliometric review and selective content review of existing research were utilized. Relevant publications for the aforesaid analysis were delineated using the source concepts “resilience”, “adaptation”, “adaptability”, and “Southern African Development Community” (or “SADC”). Using the SCOPUS database, bibliometric data of 65 publications were imported into the VOSviewer application (v.1.6.17). Keyword occurrences and network and overlay visualizations were applied to identify the research themes underlying current research. The findings, which were supported by the selective content review, indicate that existing research focuses primarily on environmental and social disturbances, while the applicable regional planning scale and development policy are considered to a limited extent. Areas of future research ought to create evidence that is thematically relevant to policy areas and applicable to policy interventions, which necessitates increased research on economic disturbances, a broadening of existing themes to the appropriate regional planning scale, and consideration of explicit regional development objectives and policy. Transdisciplinarity ought to be central to future research on the diverse disturbances facing the region, while researchers ought to leverage knowledge-creation opportunities catalyzed by SDG implementation.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76788740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Brazil does not have its own way for treating printed circuit boards, a key component present in this type of waste. In this context, the processing of these components would allow the extraction of metals with high added value, mainly copper, silver, gold, and palladium. The purpose of this research is to design a conceptual treatment route, based on the integration of technologies described in the literature. After creating the route design, a mass and energy balances were performed, considering two printed circuit board source as raw material: (Case A) Wasted equipment in general; (Case B) Using only cell phones. For both cases, the treatment of 2 t·h−1 was considered. In addition, cost estimates and plant sensitivity analysis were carried out. For 15 years of plant production, the calculated Capex was USD 2,002,682, where an internal return rate of 140.1% and 3933.0% was obtained for Case A and B, respectively, and a net present value of USD 44,403,373 and USD 3,210,393,496 for Case A and B, respectively. Additionally, it was observed that Case A has a great sensitivity to the variation of the processing volume. Based on the present findings, this theoretical research has the potential to be a nucleation point in the design of a future industrial plant dedicated to the recycling of printed circuit boards, as well as to understand the key variables for the processing these components, based on Brazilian circumstances. Additionally, the project presents the hypothetical investment required for the creation of such conceptual plant, which is a crucial piece of information for potential investors.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"141 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83935666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toerien","doi":"10.3390/world3030022","DOIUrl":"https://doi.org/10.3390/world3030022","url":null,"abstract":"Urbanization is one of man’s greatest challenges. Its handling requires a better understanding of orderliness in the demographic–socioeconomic–entrepreneurial domain of human settlements. Operating business enterprises are manifestations of successful entrepreneurship, which is the characteristic of interest here. Non-linear entrepreneurial proportionalities can be detected through the use of log–log regressions (power law analyses). Such analyses revealed many entrepreneurial proportionalities in datasets of a large number of U.S. counties. This enabled the examination of the temporal and geographic sensitivities of three entrepreneurial types: total entrepreneurship (expressed in total enterprise numbers), new entrepreneurship (the ability to successfully start enterprises of types not yet present), and existing entrepreneurship (the ability to start more enterprises of types already present). Stress testing of the entrepreneurial proportionalities during a period of economic growth (2000 to 2007) followed by a period of economic decline (the so-called Great Recession from 2007 to 2010) enabled the examination of a hypothesis that suggested that the entrepreneurial proportionalities are not temporally or geographically sensitive. The hypothesis is accepted for new and existing entrepreneurship. Total entrepreneurship is geographically sensitive, but not temporally. There is apparently no lack of entrepreneurship in human settlements. Their total entrepreneurship (expressed as total enterprise numbers) appears to be a function of their population sizes and prosperity/poverty levels.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87469078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although easy-bike has become a prevalent form of paratransit among city-dwellers in medium-sized cities in Bangladesh, many passengers are now avoiding such paratransit to maintain health and safety guidelines during the COVID-19 pandemic. The pandemic has negatively affected easy-bike drivers’ income in many medium-sized cities. To conduct this study, we collected primary data from the field, with the health and safety guidelines recommended by the government of Bangladesh in consideration. The results demonstrate a decreasing number of trips due to government policy changes under the COVID-19 pandemic, influencing people’s earnings associated with this transit system. We summarized the data to capture the attention of policymakers, who may need to introduce any foreseeable action to assist workers of different professions in need of economic assistance in cities outside of the capital city in Bangladesh. Moreover, we suggest the need to consider these urban transport workers as a vulnerable group for livelihood assistance within the country.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87650403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assess the availability of natural resources and the resulting carrying capacity (a basic concept of environmental determinism) through a toy model based on Hurst–Kolmogorov dynamics. We also highlight the role of social cohesion, and we evaluate it from an entropic viewpoint. Furthermore, we make the case that, when it comes to the demise of civilizations, while environmental influences may be in the mix, social dynamics is the main driver behind their decline and eventual collapse. We examine several prehistorical and historical cases of civilization collapse, the most characteristic being that of the Minoan civilization, whose disappearance c. 1100 BC has fostered several causative hypotheses. In general, we note that these hypotheses are based on catastrophic environmental causes, which nevertheless occurred a few hundred years before the collapse of Minoans. Specifically, around 1500 BC, Minoans managed to overpass many environmental adversities. As we have not found justified reasons based on the environmental determinism for when the collapse occurred (around 1100 BC), we hypothesize a possible transformation of the Minoans’ social structure as the cause of the collapse.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89333253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to perform an epidemiological analysis of the COVID-19 pandemic in Uberlândia, Minas Gerais, in 2021, highlighting the impact of government commercial policies on pandemic control. This is an epidemiological, observational, and analytical study with secondary data. We constructed a regression for count data using the Poisson model. Data adherence to the regression was verified by Cameron & Trivedi and the Likelihood Ratio tests. According to the Poisson model, there was a statistically significant association (p < 0.001) between the adoption of rigid commercial interventions and the drop in deaths. Moreover, we revealed a consistency between the economic policies and the number of screening tests applied, which may have contributed to the deaths behavior. This study shows the importance of institutionalizing economic policies and their positive impacts on pandemic control; however, it raises the discussion about the serious repercussions of these measures on population vulnerability.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82330923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zörner","doi":"10.3390/world3020018","DOIUrl":"https://doi.org/10.3390/world3020018","url":null,"abstract":"In rural Kyrgyzstan, the energy need is usually derived from multiple natural energy resources such as firewood, charcoal, agricultural residues, animal dung, and wood branches, which are considered common and predominant practices. Because of the non-sustainable resources and heavy reliance on the environment, Kyrgyzstan is one of the most vulnerable countries to climate change in Central Asia. On the contrary, the great renewable energy potential in Kyrgyzstan is untapped, which could be the most promising solution to ensuring sustainable energy supply in the country. However, because of the lack of scientific knowledge, current energy policies, and the lack of infrastructure, renewable resources are mainly untapped. To exploit the country’s renewable energy potential, there is a need for a systematic diagnosis to develop a strategy to explore renewables in Kyrgyzstan, which is currently missing in the existing literature. In that regard, the presented study aims to assess the current status of renewable energy sources by considering the local energy context from a potential point of view. Further to this, it provides a comparative overview through a matrix of strengths, weaknesses, opportunities, and threats. Such novel analysis would be the fundamental base for formulating policy advice and a national plan to enhance the utilization of renewable energy in Kyrgyzstan. The presented analysis was carried out based on the extensive literature review, the country’s national plan, and the existing energy policies of Kyrgyzstan. The article found out that there is huge potential available for the renewable energy market. As compared to other renewable energy sources, solar energy has great potential and can be considered one of the pioneer sustainable sources for integration into the country’s power generation framework.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90098359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By introducing the concept of “growthless employment” it demonstrates that the implementation of internal devaluation policies had a substantial impact on the Greek society that needs to be addressed. Within a decade, household disposable income was reduced to an unprecedented level while the labour market was extensively deregulated as several indicators can display. The seemingly paradoxical case of employment without growth—hence, growthless employment—can be interpreted as the consequence of the intensity of the mix of austerity policies that was imposed as “one-size-fits-all” without taking the peculiar structure of the Greek economy into account. A descriptive examination of this idiosyncratic state of affairs is offered, providing new insights on how the level of depreciation can be better assessed. It is argued that the overall severity of the crisis is better captured by the level of disposable income whereas a modified measurement of poverty and income depreciation is introduced for the same purpose. Lastly it is maintained that Greece has suffered by an enormous outflow of its productive-aged population in the aftermath of the crisis. All the above concretise the idea of growthless employment in Greece.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90175917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
