Abstract
Open Science paradigm involves transformations throughout the entire cycle of scientific research. Decision-makers play the key role of paradigm change facilitators. Consequently, the promotion of Open Science requires a political commitment.
Even though Open Science movement emerged at the international level back in 2002, its principles are being implemented quite slowly in the Republic of Moldova.
Thus, the current study aims to analyze the importance and benefits of Open Science policy implementation, the strategic priorities of the Republic of Moldova on Open Science, barriers in transition to Open Science in the Republic of Moldova, and identification of the key actors in development, adoption, and implementation of Open Science policies in the Republic of Moldova.
The study employed a mixed method: survey among members of the scientific community (quantitative data collection) and semi-structured interviews of the key informants in Open Science policies and practices (qualitative data collection).
When social policy walks into the justice system...

Published: October 2023

Abstract
This paper aims to elaborate on the dilemmas Hungarian courts face when they appear in the forefront of policy implementation. Firstly, what kind of (legal) sources and documents should the court involve in in its legal interpretation? Secondly, what are the trade-offs between offering effective remedy sanctions and respecting the differences between branches of law and the division of power? For purpose of this analysis, we turn to the example of school segregation lawsuits between 2007 and 2022. In terms of equal and equitable education, the regulatory frameworks in the CEE Countries are harmonized to the EU standards and are strongly based on the anti-discrimination approach. In theory, policy programs and documents could be used as a source of facts, as well as a source of information regarding legislative goals and policy context. In theory, courts should aim to opt for sanctions with the most potential to achieve effective remedy. If this leads to specific policy-type sanctions, within the bounds of the parties’ actions courts should be able to decide so. However, courts tend to refrain from such sources and decisions. In the context of democratic backsliding the possibilities of such activism are somewhat unclear. Issues around the independence of the judiciary, the attitude of the executive branch towards certain social policy issues, and the practice of overwriting by amendment on part of the National Assembly supermajority may discourage courts and judges from policy-sensitive or innovative adjudication of cases with social policy relevance.
Link Adaptation Strategy for Underwater Acoustic Sensor Networks: A Machine Learning Approach

Published: October 2023

AbstractDue to growing concerns regarding their use in fields including oceanography, commercial marine operations, and military surveillance, demand in the exploration of underwater sensor networks for marine studies has developed. Network channels for underwater sensor network (USN) rapidly change (spatially and temporally) depending on the surroundings. To increase system efficiency by adjusting transmission parameters to channel fluctuations, it is alluring to utilize adaptive modulation and coding (AMC) for USNs. In order to determine the best link adaptation method based on the channel quality, this article focuses on evaluating a measured sea trial dataset utilizing a rule-based approach (i.e., three-dimensional evaluation, modulation-wise analysis, and a fixed-SNR strategy). To determine the optimum AMC combinations in terms of channel adaptively, we draw a situation of the measured USN data rate versus Bit Error Rate (BER) and Signal to Noise Ratio (SNR). The work further extends to apply machine learning (ML) methods to identify the MCS levels by looking into the channel characteristics due to the non-reversibility limitation of the rule-based strategy. One of the ML methods we used for the investigation, gradient boosted regression tree (GBRT), exhibits impressive accuracy of 99.988% in classifying MCS levels. The MCS levels are related to channel statistics and signal characteristics, particularly those that are susceptible to SNR and BER limitations, using an ensemble of trees that learns from the buoy and base station’s uplink data.

Abstract

BACKGROUND. Sleep-breathing disorders are increasingly common in the general population, affecting the quality of life from many points of view. Patients with sleep-disordered breathing have a series of comorbidities, including arterial hypertension, which affects the quality of life also through the collateral manifestations of daytime sleepiness.

MATERIAL AND METHODS. A descriptive study was conducted on a group of 134 patients who underwent investigations to determine the degree of obstructive sleep apnea syndrome (OSAS) by respiratory polygraphic and polysomnographic investigations. This group was also investigated from the point of view of blood pressure values as well as the degree of daytime sleepiness, an important element for the quality of life.

RESULTS. The average age of the evaluated patients was 42.18±12.70 years, and the body mass index was 31.20±5.74 kg/m2. The assessment of systemic blood pressure indicated an increased value above its standard normal value in most subjects: 58 patients (43.9%) were included in stage I hypertension, 9.8% in stage II, 1.5% of the subjects were diagnosed with stage III hypertension. To describe the relationship between OSAS and quality of life assessed by the degree of daytime sleepiness, we performed the regression and correlation analysis. The dependence between the values of the apnea-hypopnea index (AHI) and the ESS (the degree of daytime sleepiness) was positive; an increase in the AHI implies an increase in the ESS, thus a decrease in the quality of life.

CONCLUSION. We can conclude that the severity of OSAS is directly involved in establishing the degree of arterial hypertension. Moreover, early detection is essential in order to decrease the degree of daytime sleepiness and implicitly increase the quality of life.

Published: October 2023

Purpose: The purpose of this study is to propose a set of parameters for urban, environmental, and habitability impacts for the feasibility analysis of social housing projects.

Theoretical framework: Given the historical housing deficit, the large scale of social housing segment has been challenging managers in terms of environmental (volume of inputs, energy, waste), economic (high investment), and social (urban relations) impacts. Thus, efficiency in the performance of Social Housing Projects is a relevant aspect, regarding the importance that housing represents in users’ lives.

Method/design/approach: The research strategy used was case studies, using 12 social housing projects built in Rio de Janeiro and Porto Alegre. The parameters analyzed refer to urban, environmental and habitability impact, based on data collected in loco, seeking to identify the main variables that influence each one, categorized as greater, medium or smaller influence.

Results and conclusion: The variables with the most significant impact were: (i) mobility, access to opportunities, degree of localism, and social networks (urban parameters); (ii) index of compactness of the buildings and place of manufacture of the materials (environmental parameters); (iii) bioclimatic zone, facade color, window size, architectural type, and (iv) construction system (living parameters).
Research implications: The proposed parameters may be helpful to public authorities (funders/inspectors), designers/builders (executors), and academics (theoretical/technical support) as a guide to more efficient social housing solutions involving the construction of programs, guidelines for public notices, parameters assessment, among others.

Originality/value: The study contributes to the existing literature by encompassing a systemic approach to EHIS, being propositional through parameters that integrate issues related to construction and urban performance.
