Perder a mãe: uma jornada pela rota atlântica da escravidão, por Saidiya Hartman
Authors: Cunegundes Guimarães Patrícia
Published: February 2023

A partir de um mergulho na história do comércio atlântico de escravos[1], saindo de Gana para as Américas, Saidiya Hartman tenta preencher as lacunas da história africana, afro-americana e de sua própria família, numa “fabulação crítica” construída a partir dos silêncios, da falta de arquivos e de sua experiência vivendo em Acra, capital ganense, no fim dos anos de 1990. Perder a mãe: uma jornada pela rota atlântica da escravidão investiga a paisagem ganense, o oceano Atlântico e as ruínas do período da escravidão como arquivos possíveis, refletindo também sobre o mito do pertencimento, sobre ter o “próprio parentesco, o próprio país, a própria identidade negados” (p. 108).

Fully Passive Noise-Shaping SAR ADC Realizing 2X Passive Gain Without Capacitor Stacking
Authors: Zou Xingshuai , Liu Jiaxin , Li Qiang
Published: February 2023

The fully passive noise shaping (NS) successive approximation register
(SAR) analog-to-digital converters (ADCs) are simple, OTA-free and
scaling friendly. Previous passive NS-SAR ADCs rely on the
multi-path-input comparator or capacitors stacking to realize the
passive gain for compensating the signal attenuation during passive
integration. However, the former causes high comparator power
consumption, and the latter suffers from additional signal attenuation
due to the parasitics and is hard to extend to high-order systems. This
work proposes a new fully passive NS-SAR technique, it can realize 2×
gain with a simple structure, leading to the reduced comparator power
and less parasitics. This technique is also easy to extend to high-order
NS-SAR ADCs.

Published: February 2023

Electric vehicles (EVs) are a very essential part of the automobile industry and play a vital role in the development of the economy of a country. Due to their eco-friendly nature and lower operating cost, EVs have acquired great attention globally. Almost all leading automobile manufacturers are developing cost-efficient EVs. However, with the increase in the number of EVs day by day, the need for efficient charging stations to deliver economical charging needs to be developed. To charge these EVs from the conventional grids is an additional burden on these grids as more electricity will be required to charge these EVs, which may result in incremental energy production as well as the energy cost for the general consumers. These days, increasing the number of EVs can bring sustainability problems in Pakistan as the considered country already facing the worst electrical energy crisis in the last ten years. For this purpose, we must require some alternate methods for charging the EVs charging to avoid overloading on existing grids. The use of renewable energy resources (RERs) is an effective solution to tackle this shortage of power. Therefore, in this paper, a cost-effective solution is proposed by hybridizing the different types of RERs to charge the EVs from the charging station. A different combination of RERs is used as case studies for a specific area of Pakistan named Kallar Kahar. Simulation is performed on MATLAB/Simulink and energy cost is being compared for different case studies. The proposed hybrid power system used approximately 50% wind, 40% solar, and 10% biogas as RERs. The results show that case 4 is best among all which provides yearly power production of 375,220 kWh at a net annual cost of 43,174.06$/year while the net annual cost to provide the same power with the grid is 59,304$/year. There is a 1.37% reduction in the overall annual cost of the proposed charging station as compared to the utility grid.

Published: February 2023

Commercial transactions in the digital environment represent the core of the digital economy. Progress in information technology opens up opportunities for commercial transactions in the digital environment, thereby raising operational productivity and the flow of goods and services to a new level. The digital transformation of commercial transactions occurred very fast owing to the CODID-19 pandemic, thereby contributing to a significant increase in the number of commercial transactions both globally and nationally that have become available to more than half of the world’s population. Making digital commercial transactions is affected by a number of factors: information technology infrastructure, Internet speed, digital security, consumer skills, consumer protection and delivery logistics. The research analysed data on the population using the Internet in Latvia, the EU and the world. The research identified correlations between: the number of digital commercial transactions and the population, mobile Internet speed and the number of individuals who shopped online, the categories of goods purchased online and gender, the amounts of money spent on online purchases and the employment category. In 2020, according to Eurostat, 56% of the population of Latvia made digital commercial transactions. The figure for Latvia was 8% lower than the European Union average. A comparison of the numbers of digital commercial transactions between Latvia and the other Baltic States revealed that the figures for Latvia were mediocre. The number of transactions was higher in Latvia than in Lithuania by 2%, while Estonia experienced the largest increase in the number of digital transactions, which was 12% higher than in Latvia. The comparison indicates that it is possible to increase the number of digital commercial transactions in Latvia.
Significance of financial security in environmental behaviour
Authors:   University of Latvia, Felcis Renars , Felcis Elgars ,   University of Latvia
Published: February 2023

The Intergovernmental Panel on Climate Change (IPCC) report on adaptation is demonstrating that the most vulnerable people are already disproportionally affected by the climate breakdown (IPCC, 2022: 8-9). The ongoing climate and environmental breakdown, the first two years of the COVID-19 pandemic, and the Russian war in Ukraine in early 2022 are creating a convergence of crises with grave concerns about its future unfolding and impacts on vulnerable groups. Inability to afford environmentally friendly actions might leave certain groups of society in a vicious circle. Based on quantitative social survey data from 2020 and 2021 within the Latvian Council of Science funded project ‘Ready for change? Sustainable management of common natural resources’, this paper demonstrates correlations between the financial security of people and environmental behaviour in Latvia. Financial security is measured by status of debt obligations and the length of time people can provide for themselves in case of the loss of their current income sources. We conclude that the overall financial security has significantly reduced from 2020 to 2021, while at the same time environmentally oriented behaviours have remained stagnant or less widespread. As a result of cluster analysis, three groups of financial security are distinguished and further analysis demonstrates that high income alone is an insufficient motivator for diverse environmental behaviour. Affluent people tend to do the simplest steps more often, like trying to sort their waste for recycling, while many with lower incomes and in rural areas are capable of more actions, with the overall lower consumption levels. Only thinking and acting beyond the ‘business-as-usual’ narrative can enable transformative actions to change the structural processes that keep causing the side-effects of our development.

Published: February 2023

Однією із проблем в електричній мережі з ізольованою (компенсованою) нейтраллю є селективне визначення пошкодженого елемента за однофазного замикання на землю. Для селективної та надійної роботи захистів від однофазних замикань на землю в мережах із ізольованою (компенсованою) нейтраллю, крім струму нульової послідовності приєднань, необхідна інформація про фазні напруги та напругу нульової послідовності електричної мережі. На багатьох трансформаторних підстанціях відсутні традиційні електромагнітні трансформатори напруги. Для таких підстанцій проблему вимірювання високовольтної напруги можна вирішити застосуванням ємнісних подільників. Для перевірки функціонування ємнісних подільників, призначених для вимірювання напруг секцій шин 6 (10) кВ, на кафедрі електроенергетики та систем управління розроблено фізичну модель. У схемі фізичної моделі застосовано сертифіковані ємнісні подільники, які використовують у системах індикації наявності напруги на секціях шин напругою 6 (10) кВ. Ці ємнісні подільники розробило НПП РЕЛСіС. Розроблено пристрій для узгодження під час функціонування схеми вимірювання напруг сигналів, які подаються з ємнісного подільника на вхід цифрового реєстратора. Для перевірки роботи ємнісних подільників у схемі фізичної моделі застосовано традиційний електромагнітний трансформатор напруги типу НТМИ-10-66, з вторинної обмотки якого напруга подається на цифровий реєстратор. Здійснено перевірку запропонованої системи в основних режимах роботи. Для аналізу записаних цифровим реєстратором осцилограм розроблена спеціальна програма. Ця програма містить функції аналізу координат режиму, які дають змогу виконувати гармонічний аналіз, здійснювати розрахунок симетричних складових, формувати інтегральні, диференційні характеристики тощо. З використанням перетво- рення Фур’є розроблено цифрову модель, яка дає змогу визначити діючі значення виміряних напруг та виділити їх симетричні складові – нульової та зворотної послі- довностей. Дослідження показали, що вимірювання високої напруги за допомогою ємнісних подільників можна застосовувати в схемах із пристроями, для функціонування яких необхідний контроль фазних напруг мережі 6–10 кВ.

Published: February 2023

As a country prioritizing development and economic growth, Türkiye needs to set policies and targets for the development of human capital. To be able to do this, it is necessary to start with the analysis of the higher education (HE) policies and objectives in the development plans that have been prepared since the beginning of the planned development period. Aiming to determine HE policies and objectives on the basis of development plans, this study is expected to contribute to the field by guiding HE policymakers and quality system practitioners in Türkiye. Focusing on the HE policies and objectives in 11 development plans prepared in Türkiye from 1963 to 2019, the study was designed as a document review, following the qualitative research paradigm. The data obtained in the research were analyzed by applying the content analysis technique. During the analysis of the data, first of all, the development plans were subjected to content analysis, and the results related to the HE policies and targets were then identified and interpreted. The research revealed five themes related to the policies and objectives in the development plans (development of HE, support in HE, planning in HE, cooperation in HE, and financing of HE). Some policies and targets in the development plans were found to recur frequently. It was also observed that the dominant philosophical paradigm of the period was followed in the preparation of the plans, with no paradigmatic blindness. Based on the findings, decision-makers are suggested to adhere to the policies and objectives determined in the development plans, and researchers are suggested o conduct research by analyzing the development plans and the National Education Council decisions together.
