Navigating Ideological Divides: Alternative Feminist Discourse(S) Within the Romanian Contemporary Literary Sphere
Authors:   Babeș-Bolyai University, Huțanu Diana , Tite Alisa ,   Babeș-Bolyai University
Published: February 2025

This paper aims to analyse the emergence of alternative feminist platforms (such as Literatură și feminism, Premiile Sofia Nădejde, Buletin de știri Ecaterina Arbore, Cooperativa arbore, Pagini libere, Cenaclul X, frACTalia) within the context of an ideologically divided Romanian literary sphere. The national political climate registers conservative attitudes towards feminism as volatile. They oscillate between that of “opportunist non-sexists” (Grünberg, Lived Feminism(s)), who appropriated the movement for cultural capital, and the outright rejection of feminism, understood as inextricably linked to imported Western ideology (Miroiu, Drumul către autonomie). In response, our paper implements a double perspective: one that juxtaposes instances of feminist appropriations with leftist feminist articulations. We first adopt a birds-eye view, examining the post-communist political climate that gave rise to waves of “retraditionalization” in Eastern European countries (Bluhm et al.), as well the issue of alignment or synchronisation of feminist ideals with similar local and global movements. Then, we showcase the means of disseminating anti-genderist and anti-feminist ideas within the Romanian academe, as well as the larger civil society. Lastly, we aim to highlight alternative feminist platforms, which we interpret as feminist “counterpublics” (Fraser; Majewska) able to form sites of resistance within the masculinist public sphere. Our study highlights convergent time-frames or temporal coherence within alternative feminist discourses, illustrating how non-liberal feminists sometimes coordinate actions and responses to better address social struggles.

Understanding the ESG and Financial Performance Relationship: Different Metrics Matters
Authors: Widyawati Luluk
Published: February 2025

Studies on the relationship between environmental, social, and governance (ESG) and a firm's financial performance remain largely inconclusive. This study attempts to provide empirical evidence that the disagreement among ESG ratings lead to the different results of firm-level studies on the relationship between ESG and financial performance. Tests of multiple models using different ESG rating uncover three types of variations: statistical significance, directionality, and magnitude. This study also indicates that the effect is greater in studies on accounting-based financial performance measures and studies applying composite ESG score. Social dimension consistently presents the highest number of variations compared to environmental and governance dimensions.

Authors: Ahada Ichi , Hermagustiana Istanti
Published: February 2025

This research aims to explore student beliefs regarding self-reported feedback on their speaking performances in English classes. It investigates what beliefs students hold about receiving self-assessed evaluations and delves into how these assessments can identify both strengths and weaknesses in English-speaking abilities. Using a qualitative case study approach involving interviews with three highly self-regulated learners, the study highlights the significance of self-assessment for improving speaking skills. While acknowledging that self-assessment has its limitations—such as insufficient English proficiency, restricted practice opportunities, and emotional hurdles—the research emphasizes incorporating external feedback from peers, teachers, or technological tools to enhance learner comprehension of their speaking capabilities. Ultimately, addressing these challenges through integrated teaching methods could optimize the efficacy of self-assessment practices in enhancing language learning outcomes.

Published: February 2025

Tourism in Bali is a hallmark of economic prosperity, attracting millions of tourists every year due to its natural beauty, rich cultural heritage, and preserved cultural heritage. Behind this vibrant industry are millions of labors whose livelihoods depend directly or indirectly on tourism. The research explores the financial well-being of the Millennial Generation (Generation Y) and Generation Z labors in the Bali tourism sector. This method uses a quantitative approach with crosstab analysis facilitated by SPSS Statistics 25, which was collected via questionnaires from 151 tourism labors in Bali.  The main findings show that although levels of financial well-being vary between generations, most respondents said they were happy with their finances. In addition, income disparities are visible, with the higher the age of tourism labors in Bali, the higher their income. However, regarding perception, financial well-being is relative, whereas generational age does not always influence financial well-being.  This research contributes to a deeper understanding of the dynamics of financial well-being among Bali tourism labors. The results of this research are expected to create strategies to increase income stability, job security, and financial literacy, which are recommended to support the tourism sector sustainably and improve the overall welfare of labors in Bali.

Authors:   Academy of Policy and Development, Vietnam, Bao Nguyen Van , Cho Yoon Cheong ,   KDI School of Public Policy and Management, Korea
Published: February 2025

Research on child marriage has predominantly focused on girls, leaving boys’ experiences largely understudied. This study aims to address this gap by exploring the experiences of child brides and grooms, emphasizing the distinct disadvantages each gender faces. Specifically, it investigates the following research questions: (i) What health and reproductive outcomes are associated with child brides and grooms? (ii) How does child marriage influence discriminatory attitude and stigma among boys and girls? (iii) How does child marriage impact the subjective well-being of both genders? Logistic regression analyses were performed using data from the Multiple Indicator Cluster Surveys (MICS), a nationally representative survey conducted in Vietnam. The findings revealed significant associations between child marriage and early parenthood for both boys and girls. Child brides were more likely to express negative attitudes toward domestic violence and hold discriminatory views about HIV-positive individuals. Meanwhile, child grooms exhibited a higher likelihood of feeling ashamed of living with HIV-positive individuals. Gender differences also emerged in subjective well-being outcomes. Boys who married early were less likely to perceive their lives improved than those who married later, whereas early-married girls were more likely to have a positive view of their lives. The findings hold significant implications for shaping initiatives to prevent and mitigate child marriage, not only in Vietnam but also throughout the Southeast Asia region.

When benign pretends to be malignant: A case report of giant cell tumor of the breast with review of literature
Authors: Aggarwal Depanshu , Nair Rishi P , Kumar Parmod , Devnani Bharti
Published: February 2025

A giant cell tumor (GCT) of the breast is an uncommon intermediate-type soft tissue tumor with histological features resembling its osseous counterparts. To date, only 12 such cases have been documented. Our case involves a 58-year-old woman who initially presented with a breast lump progressively enlarging over six months. It was evaluated as a potential case of breast cancer. Mammography, biopsy, and, subsequently, positron emission tomography-computed tomography (PET-CT) were conducted for staging. The core biopsy specimen did not conclusively differentiate between the two suspected pathologies, i.e., GCT and Invasive breast cancer with osteoclast-like giant cells, although it was favoring the former. Following a multidisciplinary tumor board (MDTB) meeting, the patient underwent a total mastectomy and axillary lymph node dissection (TM+ALND). The large biopsy was suggestive of GCT of the breast.

We have conducted an exhaustive review of the literature on GCT of the breast, encompassing its presentation, radiological findings, differential diagnoses, and treatment modalities to formulate a structured approach for management. Additionally, we performed a statistical analysis of baseline characteristics, outcomes, and treatment modalities to succinctly summarize the current data on this subject.

В ходе исследования была проведена экспериментальная обработка речевого сигнала, содержащего голосовую команду, путём его сегментирования выделения пассивной фазы сигнала с дальнейшей коррекцией в среде Matlab. По результатам экспериментального исследования цифрового фильтра нижних частот выявлено, что качество полученного аудиосигнала улучшается на 9 дБ по сравнению с исходным аудиосигналом.

Relevance. Facilitating human interaction with information systems ranks among the foremost priorities in the field of information technology. The investigation of speech signal parameters, considering the operational intricacies of voice control systems, along with devising a novel methodology grounded in the bionic approach and crafting dual-purpose voice control systems with enhanced attributes, are pressing objectives. The aim of this study is to improve the characteristics of dual-purpose voice control systems, employing the bionic approach, for deployment in both standard scenarios and emergency situations. Materials and Methods. The bionic method of object control involves harnessing various expressions of body vital activity as control signals for instruments, mechanisms, and devices. Our approach entails a unique sequence of procedures, incorporating additional digital processing of the speech signal. This enables the detection of interference and noise peculiar to the signal-interference environment during pauses in the speech signal, where the voice control system operates. Experimental processing of a speech signal containing a voice command was conducted in the Matlab environment, involving segmentation and isolation of the passive phase of the signal. Results and Discussion.Computational analysis revealed that the signal-to-noise ratio for the original audio signal, containing the speech command, measured at 19.2896 dB, whereas for the segmented audio signal – devoid of pauses between words – it was 25.2658 dB. Conclusion. The study validated the authors' hypothesis regarding the augmentation of noise suppression in voice control systems through the monitoring of interference during the passive phase of the speech signal. Future research endeavors are warranted to refine the segmentation and digital filtering techniques applied to speech commands in voice control systems.

Introduction. Currently, there is significant focus on researching metal oxide films and developing production technologies to create innovative devices widely utilized across various industries and scientific fields. Many of these devices rely on photoinduced processes, such as photocatalytic activity and superhydrophilicity. This study specifically examines the superhydrophilic property of titanium oxide films. The primary parameter used to assess this property is the contact angle, which approaches 0° in superhydrophilic surfaces. However, existing studies have not provided a comprehensive understanding of the mechanisms or causes behind superhydrophilicity on titanium oxide film surfaces. Therefore, achieving superhydrophilic films requires reliance on advanced technologies and production methods. Among these methods, reactive magnetron sputtering stands out due to its superior properties. The novelty of this study lies in demonstrating that titanium oxide films produced by reactive magnetron sputtering exhibit higher superhydrophilic properties compared to those previously reported. The aim of the workis to develop a technology for forming superhydrophilic titanium oxide films using reactive magnetron sputtering and experimentally identify parameters that affect their superhydrophilic properties. Conclusions. A series of samples was obtained using the UVN-71P 3 vacuum unit. Data analysis from all experiments revealed that the superhydrophilic properties are influenced by the thickness of the titanium oxide film, the concentration of argon and oxygen, the substrate temperature, and the substrate material. Additionally, the composition of the droplets affects the superhydrophilic properties. Parameters such as the distance between the target and the substrate (100 mm) and the target current (1.5 A) remained constant in all experiments.

The impact of political instability in attracting foreign investment (Case of Albania)
Authors: Gorjani Gerta , Rama Shezeina
Published: February 2025

The aim of this study is to define the impact of political instability on economic growth. Considering the multidimensionality of a factor like political instability, the study employs only four variables to measure it. The variables used to measure political instability are civil liberties, political rights, number of women in parliament and the government changes during years. Regarding the economic growth this study employs the variable of real GDP growth rate as the best factor indicating economic growth. The data are obtained from national and international sources like “INSTAT”, “Bank of Albania” and “The Global Economy”, and takes into consideration the period from 1990-2015. According to the literature it was expected to have a significant negative impact of political instability on economic growth. Through the results obtained from the econometric model the expectation holds. What is interesting is the insignificance of all explanatory variables beside the variable of civil liberty, which is found to be highly significant. The analysis reveals that an increase in civil liberties would have a positive impact on GDP growth rate.  The study also concluded that the importance of civil liberties as a transmission channel of political instability can be justified with the weakness of the judicial system and the classification of Albania as a partly-free country. The comperative method was used in this study. The topics discussed and addressed are freedom and rights, their development over the years, women in politics, participation and increased representation, economic changes, crises and their causes and how it has evolved with democratic developments.
Biosynfoni: A Biosynthesis-informed and Interpretable Lightweight Molecular Fingerprint
Authors: Nollen Lucina-May , Meijer David , Sorokina Maria , van der Hooft Justin
Published: February 2025

Natural products provide a rich source of bioactive molecules for a variety of applications. Molecular fingerprints are the tool of choice for systematic large-scale studies of their structures. However, current molecular fingerprints insufficiently represent characteristic features of natural products inherently, decreasing the interpretability of natural product-specific predictions. Here, we show that a natural product-specific molecular fingerprint based on a relatively small set of selected biosynthetic building blocks provides more interpretable predictions of biosynthetic distance and natural product classification. Our fingerprint Biosynfoni outperforms MACCS, Morgan, and Daylight-like fingerprints in biosynthetic distance estimation, using 39 substructure keys.

Homochirality represents a hallmark of life, and its emergence on the pre-biotic Earth remains elusive. Here we demonstrate a spontaneous pathway to homochirality, where a conglomerate-forming chiral species evolves from an initial perfectly symmetric state, i.e., a racemic solution, to a fully homochiral state, where only enantiopure crystals of one handedness are present in the suspension. It entails first the establishment of supersaturated conditions, e.g., because of either solvent evaporation or cooling, then stochastic nucleation of enantiopure crystals as the symmetry breaking event, and finally asymmetry amplification and complete deracemization via temperature fluctuations. After developing a stochastic modeling platform and an experimental setup, we confirm the plausibility of this pathway through both detailed simulations and laboratory experiments. We also show how from a variety of local homochiral states of different handedness, a global homochiral state may emerge via merging and deracemizing. Because the external conditions triggering supersaturation creation, nucleation, and deracemization via temperature cycling must have existed also on the pre-biotic Earth, the proposed spontaneous pathway may indeed have played a role in the emergence of life on Earth.

The research survey aimed to assess the impact of climate change on the livelihoods of people in wards 4, 5, 6, and 7 of Rajpur Rural Municipality, Dang. Conducted in November 2023, the survey employed a sample of 85 individuals using a proportionate stratified sampling method and included semi-structured interviews, focus group discussions (FGD), and key informant interviews. While 60% of respondents remained unfamiliar with the term “climate change,” all acknowledged experiencing its effects. Participants identified challenges in agriculture and forest ecosystems, with notable issues such as disease and pest infestation, increased droughts, and floods ranking as primary direct problems. Indirect problems included the disappearance of landrace varieties and decreased soil fertility. Water resource concerns encompassed reduced water availability, heightened vulnerability to floods and landslides, and a decrease in water table depth. Forest-related challenges involved the emergence of invasive weed species, reduced biodiversity, increased bare lands, and heightened vulnerability to wildfires. Climate change impacts on the spring season crop included delayed rainfall, heightened susceptibility to drought during cropping and fruiting seasons, and increased losses due to heavy rainfall during harvesting. The overall effects included challenges in selecting suitable adaptive crop cultivars and difficulties in determining precise planting and harvesting times due to erratic climate patterns. Farmers responded to these challenges by adopting high-yielding hybrid varieties, transitioning from cereal crops to vegetables, increasing chemical usage, and installing irrigation facilities. To cope with changing climate conditions, farmers expressed a need for technical assistance, training, and awareness programs, specifically addressing crop disease and pest management, irrigation, the availability of adaptive cultivars, and marketing opportunities.

Indian cinema, particularly Bollywood, has a significant influence on the Indian people and has achieved international acclaim (Bandyopadhyay). Bollywood films are based on a variety of themes, ranging from family values, love, gender inequality, patriarchy, identity, nationalism, and so on (Bandyopadhyay). Analysing Bollywood films from an ecofeminist perspective will uncover how women and the environment are portrayed in these films. Ecofeminism emphasises how patriarchal authority maintains the subjugation of women and the environment (Gallhofer). It challenges the anthropocentric perspective of deep ecology and emphasises the gendered nature of oppression (Gallhofer). In the context of Indian cinema, Ecofeminism can shed light on the portrayal of the domination of women and nature (Bandyopadhyay).

Therefore, the current study examines how the movie Sherni depicts the exploitation of nature and the environmental implications of human actions. The study focuses on how the film exposes the link between the subjugation of women and the degradation of the environment while also criticising the capitalist structures that fuel this exploitation. It provides an insight into the representation of women and nature in the film. By examining these aspects, it can contribute to a deeper understanding of the social, cultural, and environmental implications of Bollywood cinema.

To improve the understanding of the response patterns of river basins to climatic variability, especially with regards to basin planning, the present study utilized Remote Sensing coupled with SCS.CN and NRCS estimation methods to generate rainfall and streamflow of ungauged Okhuwan and Okhaihe catchments in Benin City. The correlation coefficients ranging from 0.83 t0 0.86 between Nigerian Meteorological Agency NIMET data and estimated rainfall were used as indicators of the model effectiveness. Estimated mean annual value ranged from a minimum value of 1443.9 mm in Obadan town to a maximum value of 1499.2mm in Okhuwan catchment, while in Okhaihe catchment, the lowest annual rainfall of 1176.6 mm was estimated for Ayen town and 1217.3 mm being the maximum annual amount in Edopa/Odjeva town. In Okhuwan catchment estimated mean annual streamflow values are 158.6 m3/s and 184.4 m3/s using SCS-CN and NRCS methods, while in Okhaihe catchment annual streamflow values were 166.3 m3/s and 163.5 m3/s using SCS-CN and NRCS methods respectively. Volumetric fluid flow rate (Q) was integrated with other variables such as density of water (ρ), gravity constant (g), height (h) and efficiency coefficient (η) to generate the potentials of various points across the catchments. In Okhuwan, mean power potentials were 13486.6 kW and 15194.3 kW using SCS-CN and NRCS computed streamflow values, while in Ohkaihe catchment mean power potentials were 11401.2kW and 12653.4 kW using SCS-CN and NRCS methods computed stream flow values. On the whole the investigated catchments showed great potentials for run-off-river hydropower scheme.
