Gender gaps in research: a systematic review
Authors: Rivera-Lozada Isabel Cristina , Escobar Gissel Carolina , Rivera-Lozada Oriana
Published: January 2024

Background Despite significant advancements in closing the global gender gap, there is still much progress to be made, particularly in the field of science and scientific research. Numerous studies have addressed this issue and identified a variety of factors that contribute to gender asymmetries in research. Methods This study aimed to identify the determinants of gender gaps in scientific research present in the most cited studies of the past ten years as a first step towards closing these differences. Through a systematic literature review that incorporated the Proknow-C Knowledge Development Process and Constructivism methodology. Results The results lead us to identify four dimensions to classify the determinants of the gaps in scientific research: academic supply, research policies, scientific production and researcher profile with their respective quantitative or qualitative indicators. Conclusions As a potential basis for further modeling that offers greater analytical and correlational depth, as well as the identification of targeted strategies aimed at reducing gender gaps in research.
The role of female leadership in times of financial crisis – an analysis during the COVID-19 pandemic
Authors: Sinha Tanja
Published: January 2024

In 2020 the new COVID-19-virus brought an external shock to the stock markets. In this situation effective leadership was essential to bring companies through the crisis.

Political observation showed that countries led by women managed the pandemic situation more effectively than those led by men. Therefore, the research objective of this article is to examine whether female leaders were also more successful to guide companies through the pandemic. Success in this study is defined as financial performance based on stock prices.

To find out whether female managers showed a better financial performance during this crisis, this study examined all companies listed on the German Stock Exchange, which have at least 50 % women in the board. To compare this female managed companies to firms managed mainly by male managers, a market value weighted index for the female managed companies was conducted and compared to the German Stock Index DAX by looking at several financial key figures.

The analysis of these key figures shows that female managed companies outperformed male managed companies in terms of return as well as risk in the year of the COVID-pandemic but were not able to keep their overperformance in the subsequent years. This may be an indicator that women are superior in leading a company through a crisis but suffer in terms of performance when times have calmed down.
Telehealth during the COVID-19 pandemic regarding children with plano-valgus foot after subtalar arthroereisis
Authors: Pardus Kamila , Stencel-Gabriel Krystyna , Pilecki Zbigniew , Hajzyk Marcin
Published: January 2024

Introduction: The COVID-19 pandemic brought about numerous changes. Access to health services was limited, and restrictions were imposed to prevent the spread of the disease. Consequently physical activity of children was limited due to their increased time at home, which could result in reduced physical performance and abnormal development. Aim: This study aimed to assess the access to physiotherapy and the use of telemedicine regarding children after subtalar arthroereisis surgery during the COVID-19 pandemic. Material and methods: Seventy-nine parents/guardians of children who underwent subtalar arthroereisis surgery at Chorzow Municipal Hospital Complex between May 2019 and May 2021 participated in the study. A self-administered questionnaire designed for the study was used as the research method. Results: The results showed that some respondents perceived the wait times at the National Health Service and the cost of private services as problems during the COVID-19 pandemic. However, increased problems associated with general access or course of treatment were not confirmed. Sixty-seven percent of respondents confirmed decreased physical activity in children due to the COVID-19 pandemic. One-third of parents noticed weight gain and muscle weakness in their children, while for 56% of respondents, the weight gain was not noticeable. In addition, more than 70% of the children had no complaints of pain. The results also showed that only 36.8% of respondents used telemedicine during the pandemic. Conclusions: The constraints imposed by the COVID-19 pandemic caused a decline in children’s physical activity; one-third of parents reported weight gain in their children. In addition, waiting times for physiotherapy reimbursed by the National Health Fund were long, and the cost of private physiotherapy was higher; it could not be confirmed whether more patients subsequently used telemedicine.
Regenerar la infancia y asistir a la madre historia de una política social en Colombia, 1918-1938
Authors: Gutiérrez Urquijo Natalia María
Published: January 2024

Este texto estudia el proceso de formulación y puesta en marcha de la política social dedicada a la protección y asistencia del binomio madre-hijo en la primera mitad del siglo xx en Colombia. La obra evidencia la progresiva inclusión en la agenda pública de la primera infancia y las madres pobres como nuevos sujetos de intervención en el marco de la modernización del Estado, la ‘cuestión social’ y el interés supranacional por el mejoramiento de la población. En su desarrollo, estudia las demandas sociales, la legislación, la organización y el funcionamiento de instituciones sanitarias. Además, reconstruye el papel de los médicos, en tanto funcionarios, expertos y políticos, así como la partici- pación de mujeres de elite como voluntarias y enfermeras. En este análisis se recurre a documenta- ción oficial, prensa, publicaciones médicas e informes de organismos internacionales que acercan la historiografía colombiana a las discusiones sobre la historia social del Estado en Latinoamérica.
Large-System Insensitivity of Zero-Waiting Load Balancing Algorithms
Authors: Liu Xin , Gong Kang , Ying Lei
Published: January 2024

This paper studies the sensitivity (or insensitivity) of a class of load balancing algorithms that achieve asymptotic zero-waiting in the sub-Halfin-Whitt regime, named LB-zero. Most existing results on zero-waiting load balancing algorithms assume the service time distribution is exponential. This paper establishes the large-system insensitivity of LB-zero for jobs whose service time follows a Coxian distribution with a finite number of phases. This result justifies that LB-zero achieves asymptotic zero-waiting for a large class of service time distributions as the Coxian family is dense in the class of positive-valued distributions. To prove this result, this paper develops a new technique, called “iterative state-space peeling” (ISSP). ISSP first identifies an iterative relation between the upper and lower bounds on the queue states and then proves that the system lives near the fixed point of the iterative bounds with a high probability. Based on ISSP, the steady-state distribution of the queue length is further analyzed by applying Stein’s method in the neighborhood of the fixed point. ISSP, like state-space collapse in heavy-traffic analysis, is a general approach that may be used to study other complex stochastic systems.

Published: January 2024

Objective: Toilet training is an important step in the development of children. It was aimed to examine the factors affecting the toilet training of children aged 18-36 months and the effect of professional support on training process.

Material and Methods: In the study, data was collected through a questionnaire. Quantitative method was used as the research method in the questionnaire. 214 children were divided into 2 groups (study group: 90, control group: 124) and included in the study. Toilet training in the study group was provided with professional support. In the control group, training was given by the families.

Results: The age of training onset was 25.60 months in the study group and 24.19 months in the control group. The duration of bladder, bowel control and toilet training completion in the study group was spread over time, and it was frequently between 1-30 days in the control group (p=0.001).

Conclusion: Our study showed that it would be appropriate to start training around 24 months and the process would be completed within 2 months. Especially in families that received professional support, the training processes of children were more positive.
Characterization of Grain Quality Traits of Thai Highland Glutinous Rice Landraces

Glutinous rice is popularly consumed as a staple food, processed for the snack industry, and fermented for alcoholic beverages by people in the North and Northeast of Thailand. Cooking quality traits are an important factor used to select for consumption and utilization by farmers. The target outputs of future rice breeding programs should focus on developing rice varieties with superior grain quality, particularly in relation to their utilization. Therefore, this research aims to assess the morphological characteristics and cooking quality of four populations of Thai highland glutinous rice landraces: Pa Ai Khupe (PAKP4 and PAKP5) and Khao Hao (KH2 and KH5), comparing them to two elite varieties (RD4 and RD6). Additionally, it examines the partial nucleotide sequence of genes involved in amylopectin branch length, specifically SSII3, ISA3, and PUL3. The study illustrates that the four populations of glutinous rice landraces exhibit morphological variations between and within populations in plant type, and panicle exsertion. Variations in alkali spreading value, gel consistency, gelatinization temperature, amylose content, and seed elongation ratio were observed among and within the glutinous rice populations. PAKP5 and KH5 were classified as hard rice, similar to RD4. KH2 was classified as medium-hard texture after cooking, while PAKP4 was classified as soft rice after cooking, similar to RD6. The partial target sequences of the selected genes showed a similar nucleotide sequence among glutinous rice landraces. Therefore, further studies should focus on more nucleotide sequences of the selected genes and additional genes, as implications for marker-assisted selection in glutinous rice breeding programs. This study provides information to assist in breeding strategies for grain quality in Thai glutinous rice breeding programs.

Land use change is a crucial issue when considering global dynamics and their interactions with the hydrologic properties of the soil and water management in catchment areas. Between 2017 to 2018, research was conducted on the effects of land use changes on water quality and flooding in the upper Nan River Basin. In Nan Province, land use is distributed as follows: natural forest protection covers 61.77 percent, agricultural purposes account for 35.23 percent, residential areas constitute 1.95 percent, and water usage represents 0.7 percent. The results indicate that the expansion of urban and agricultural regions has impacted the water quality of the river basin. A significant positive correlation was observed between agricultural land use and total phosphate content, while a strong negative correlation was found between forest land and total phosphate content. Residential occupancy and water quality demonstrated a strong correlation with total coliform contents. There were significant differences in water quality between the wet and dry seasons, particularly temperature, turbidity, total solids, total dissolved solids, and conductivity. Moreover, increases in annual and seasonal stream flow amounts were noted in relation to water levels and residential and construction projects.

The diversity of yeasts isolated from food waste at 40 °C was investigated and a total of 393 isolates were obtained. Yeasts were identifi ed using the D1/D2 domain of the large subunit (LSU) rRNA gene analysis. Only one (0.25%) basidiomycetous yeast was found, whereas the rest of the yeast isolates (99.75%) were ascomycetous. Candida tropicalis was the most prevalent species, with the highest frequency of occurrence, 86.67%, and the highest relative frequency, 26.97%. The yeast community in food waste exhibits great species diversity and evenness, as shown by the Shannon– Wiener index of 3.03 and Shannon’s Equitability index of 0.89. All yeast isolates were screened for their thermotolerance. Among 393 yeast isolates, 114 were found to be thermotolerant. Three yeasts, viz. Candida parapsilosis JS2-5, Wickerhamiella infanticola JS2-2, and C. parapsilosis JED8-65 were found to be high amylase, lipase, and protease producers on agar plates, yielding 946.97 ± 29.35 amylase U/mL, 153.93 ± 5.43 lipase U/mL, and 7.86 ± 0.02 protease U/mL under submerged cultivation at 40 °C. The overall fi ndings emphasize the species diversity of the yeast community and hydrolytic enzyme-producing capabilities within the thermotolerant yeast of food waste.

Coffee, a globally popular beverage, undergoes various processing methods such as natural (also known as dry process), washed (also known as wet processed), and honey (also known as pulped natural), impacting bean composition and beverage quality. Microorganisms, especially yeasts, play a crucial role in these processes. We investigated three yeasts’ effects on chemical profi les and antioxidant activity during coffee bean aging. Our fi ndings indicate signifi cant infl uences of processing method and yeast choice on antioxidant potential and physicochemical properties. Dry-processed beans demonstrated a heightened DPPH scavenging capacity, surpassing other processing methods by approximately 69.21%, while Saccharomycopsis fi buligera fermentation exhibited superior antioxidant activity, outperforming other yeasts by 69.42%. However, no signifi cant impact on SOD-like activity was observed. Coffee bean aging, not yeast or processing method, affected total phenolic content, while total fl avonoid content showed temporal variations. Quality and sensory evaluations suggest the potential for specialty-grade coffee. Coffee beans fermented by S. fi buligera using dry methods scored 83.31, while those fermented by Pichia kluyveri with wet methods scored 82.31 in SCAA evaluations. Our study emphasizes the role of specifi c yeasts in controlled fermentation for enhanced coffee sensory qualities.
Studying Materializations: A Methodology of Life Cycles
Authors: Kaufmann Mareile
Published: January 2024

How do we get to know this ever-changing world, a world that we are ourselves part of? Our research is much dependent on methods that capture the dynamics of becoming and the ways in which we are implicated in them. One methodological premise of this book is thus that ‘knowing must be reconnected with being’ (Ingold, 2011: 75). This is what Karen Barad captures in the term onto-epistem-ology: ‘we know because “we” are of the world’ (2003: 329, emphasis and quotation marks in original). Or as Maurice Merleau-Ponty would put it: we and the phenomena we study sit in the same folds (2003; Coole, 2010). There is mutuality: by doing research, we are part of making the world and the world makes us. This means that knowing the world is also a process of knowing ourselves and our influence. Accordingly, a good methodological attitude may be to allow for all elements in this complex, lively hive – including ourselves – to astonish us (Ingold, 2011; Chapter 2). While such a sense of wonder is a great vantage point for getting to know the world, we also depend on methods that enable us to grasp materializations. Grasping is the empirical, practical and material process of understanding through contact. A method of grasping takes distance from the more abstract ‘analytic’ that researchers inherited from the Cartesian split between mind and matter. This split implicates that analytics are based on the logic of the machine, the component parts of which are identified and manipulated by humans.

Published: January 2024

The rapid expansion of the Internet of Things (IoT) and advancements in quantum computing pose security challenges for IoT systems, encompassing classical attacks and quantum attacks. In this work, we concentrate on secure information exchange in the quantum IoT, mainly addressing the problem of establishing direct and secure quantum dialogue between two authorized IoT nodes located at a distance. The nonlocal quantum orthogonal product basis (OPB) is adopted for the first time, to our best knowledge, in a controlled quantum dialogue protocol, which eliminates the need for pre-key sharing or key storage. Through uniquely corresponding operations, private information is encrypted onto the nonlocal OPB, which is transmitted in one way. Compared with entangled states, the OPB is easier to prepare, thus reducing the quantum capability required for IoT nodes. Our approach achieves high transmission efficiency (57.1%) and qubit efficiency (100%) while providing comprehensive security measures that withstand various attacks and effectively prevent information leakage. Furthermore, an OPB-based self-error-correction quantum repeater is proposed to mitigate noise in the communication channel between distant IoT nodes. This repeater requires fewer physical resources compared with repeaters based on entangled states.

Published: January 2024

The valley degree of freedom that results from broken inversion symmetry in two-dimensional (2D) transition-metal dichalcogenides (TMDCs) has sparked a lot of interest due to its huge potential in information processing. In this experimental work, to optically address the valley-polarized emission from three-layer (3 L) thick WS2 at room temperature, we employ a SiN photonic crystal slab that has two sets of holes in a square lattice that supports directional circular dichroism engendered by delocalized guided mode resonances. By perturbatively breaking the inversion symmetry of the photonic crystal slab, we can simultaneously manipulate s and p components of the radiating field so that these resonances correspond to circularly polarized emission. The emission of excitons from distinct valleys is coupled into different radiative channels and hence separated in the farfield. This directional exciton emission from selective valleys provides a potential route for valley-polarized light emitters, which lays the groundwork for future valleytronic devices.
Ultrabroad bandwidth of quasi-parametric amplification beyond the phase-matching limit

Published: January 2024

Quasi-parametric amplification (QPA), a variant of optical parametric amplification, can release the phase-matching requirement owing to the introduction of idler dissipation, and thus may support ultrabroad bandwidth. Here we establish the gain-dispersion equation for QPA, which reveals the interplay of signal gain, idler dissipation and phase mismatch. The idler dissipation dramatically enhances the gain bandwidth, which breaks the limit set by phase matching. We theoretically demonstrate that QPA with strong dissipation allows high-efficiency few-cycle pulse amplification in those nonlinear crystals without a magic phase-matching solution.

We report a tunable spatiotemporally mode-locked large-mode-area Er:ZBLAN fiber laser based on the nonlinear polarization rotation technique. A diffraction grating is introduced to select the operating wavelength. Under the spectral and spatial filtering effects provided by the grating and spatial coupling respectively, stable ps-level spatiotemporally mode-locked pulses around 2.8 µm with a repetition rate of 43.4 MHz are generated. Through a careful adjustment of the grating, a broad wavelength tuning range from 2747 to 2797 nm is realized. To the best of our knowledge, this is the first wavelength-tunable spatiotemporally mode-locked fiber laser in the mid-infrared region.
Implicit model to capture electrostatic features of membrane environment
Authors: Samanta Rituparna , Gray Jeffrey J.
Published: January 2024

Membrane protein structure prediction and design are challenging due to the complexity of capturing the interactions in the lipid layer, such as those arising from electrostatics. Accurately capturing electrostatic energies in the low-dielectric membrane often requires expensive Poisson-Boltzmann calculations that are not scalable for membrane protein structure prediction and design. In this work, we have developed a fast-to-compute implicit energy function that considers the realistic characteristics of different lipid bilayers, making design calculations tractable. This method captures the impact of the lipid head group using a mean-field-based approach and uses a depth-dependent dielectric constant to characterize the membrane environment. This energy function Franklin2023 (F23) is built upon Franklin2019 (F19), which is based on experimentally derived hydrophobicity scales in the membrane bilayer. We evaluated the performance of F23 on five different tests probing (1) protein orientation in the bilayer, (2) stability, and (3) sequence recovery. Relative to F19, F23 has improved the calculation of the tilt angle of membrane proteins for 90% of WALP peptides, 15% of TM-peptides, and 25% of the adsorbed peptides. The performances for stability and design tests were equivalent for F19 and F23. The speed and calibration of the implicit model will help F23 access biophysical phenomena at long time and length scales and accelerate the membrane protein design pipeline.
Metabolic stress-induced long ncRNA transcription governs the formation of meiotic DNA breaks in the fission yeast fbp1 gene
Authors: Tsuruta Yusuke , Senmatsu Satoshi , Oe Hana , Hoffman Charles S. , Hirota Kouji
Published: January 2024

Meiotic recombination is a pivotal process that ensures faithful chromosome segregation and contributes to the generation of genetic diversity in offspring, which is initiated by the formation of double-strand breaks (DSBs). The distribution of meiotic DSBs is not uniform and is clustered at hotspots, which can be affected by environmental conditions. Here, we show that non-coding RNA (ncRNA) transcription creates meiotic DSBs through local chromatin remodeling in the fission yeast fbp1 gene. The fbp1 gene is activated upon glucose starvation stress, in which a cascade of ncRNA-transcription in the fbp1 upstream region converts the chromatin configuration into an open structure, leading to the subsequent binding of transcription factors. We examined the distribution of meiotic DSBs around the fbp1 upstream region in the presence and absence of glucose and observed several new DSBs after chromatin conversion under glucose starvation conditions. Moreover, these DSBs disappeared when cis-elements required for ncRNA transcription were mutated. These results indicate that ncRNA transcription creates meiotic DSBs in response to stress conditions in the fbp1 upstream region. This study addressed part of a long-standing unresolved mechanism underlying meiotic recombination plasticity in response to environmental fluctuation.
Comparison performance of the Bayesian Approach with the Weibull and Birnbaum-Saunders distributions in imputation of time-to-event censors

Published: January 2024

Almost all survival data is censored, and censor imputation is necessary. This study aimed to investigate the performance of the Bayesian Approach (BA) in the imputation of censored records in simulated and Breast Cancer (BC) data. Due to the difference in the distribution of time to event in survival analysis, two well-known the Weibull and Birnbaum-Saunders (BS) distributions have been used to test the performance of the BA. For each of the censored, 10,000 times were simulated using the BA in R and BUGS software, and their median or mean was imputed instead of each censor. The eligibility of both imputation methods was investigated using different curves, different censoring percentages, and sample sizes, as well as the Deviance Information Criteria (DIC), Effective Sample Size, and the Geweke diagnostic in simulated and especially real BC data. The BC data, which contains 220 patients who were identified and followed up between 2015 and 2023, was made accessible on February 1, 2023. The Kaplan-Meier, the BA, and other survival curves were drawn for the observed times. Findings indicated that the performance of the BA under the Weibull and BS distributions in simulated data is similar. The DIC index in the BC data under the BS distribution (1510) is less than the Weibull distribution (1698). Therefore, the BS distribution is preferred over the Weibull for imputation of censoring times in real BC data.

Although ubiquitous in modern vehicles, Controller Area Networks (CANs) lack basic security properties and are easily exploitable. A rapidly growing field of CAN security research has emerged that seeks to detect intrusions or anomalies on CANs. Producing vehicular CAN data with a variety of intrusions is a difficult task for most researchers as it requires expensive assets and deep expertise. To illuminate this task, we introduce the first comprehensive guide to the existing open CAN intrusion detection system (IDS) datasets. We categorize attacks on CANs including fabrication (adding frames, e.g., flooding or targeting and ID), suspension (removing an ID’s frames), and masquerade attacks (spoofed frames sent in lieu of suspended ones). We provide a quality analysis of each dataset; an enumeration of each datasets’ attacks, benefits, and drawbacks; categorization as real vs. simulated CAN data and real vs. simulated attacks; whether the data is raw CAN data or signal-translated; number of vehicles/CANs; quantity in terms of time; and finally a suggested use case of each dataset. State-of-the-art public CAN IDS datasets are limited to real fabrication (simple message injection) attacks and simulated attacks often in synthetic data, lacking fidelity. In general, the physical effects of attacks on the vehicle are not verified in the available datasets. Only one dataset provides signal-translated data but is missing a corresponding “raw” binary version. This issue pigeon-holes CAN IDS research into testing on limited and often inappropriate data (usually with attacks that are too easily detectable to truly test the method). The scarcity of appropriate data has stymied comparability and reproducibility of results for researchers. As our primary contribution, we present the Real ORNL Automotive Dynamometer (ROAD) CAN IDS dataset, consisting of over 3.5 hours of one vehicle’s CAN data. ROAD contains ambient data recorded during a diverse set of activities, and attacks of increasing stealth with multiple variants and instances of real (i.e. non-simulated) fuzzing, fabrication, unique advanced attacks, and simulated masquerade attacks. To facilitate a benchmark for CAN IDS methods that require signal-translated inputs, we also provide the signal time series format for many of the CAN captures. Our contributions aim to facilitate appropriate benchmarking and needed comparability in the CAN IDS research field.
Comparison of geological clusters between influenza and COVID-19 in Thailand with unsupervised clustering analysis
Authors: Methiyothin Thanin , Ahn Insung
Published: January 2024

The coronavirus disease (COVID-19) pandemic has considerably impacted public health, including the transmission patterns of other respiratory pathogens, such as the 2009 pandemic influenza (H1N1). COVID-19 and influenza are both respiratory infections that started with a lack of vaccination-based immunity in the population. However, vaccinations have been administered over time, resulting in a transition of the status of both diseases from a pandemic to an endemic. In this study, unsupervised clustering techniques were used to identify clusters of disease trends in Thailand. The analysis incorporated three distinct surveillance datasets: the pandemic influenza outbreak, influenza in the endemic stage, and the early stages of COVID-19. The analysis demonstrated a significant difference in the distribution of provinces between Cluster -1, representing those with unique transmission patterns, and the other clusters, indicating provinces with similar transmission patterns among their members. Specifically, for Pandemic Influenza, the ratio was 61:16, while for Pandemic COVID-19, it was 65:12. In contrast, Endemic Influenza exhibited a ratio of 46:31, with a notable emergence of more clustered provinces in the southern, western, and central regions. Furthermore, a pair of provinces with highly similar spreading patterns were identified during the pandemic stages of both influenza and COVID-19. Although the similarity decreased slightly for endemic influenza, they still belonged to the same cluster. Our objective was to identify the transmission patterns of influenza and COVID-19, with the aim of providing quantitative and spatial information to aid public health management in preparing for future pandemics or transitioning into an endemic phase.
How, and why, science and health researchers read scientific (IMRAD) papers
Authors: Shiely Frances , Gallagher Kerrie , Millar Seán R.
Published: January 2024

Objectives

The purpose of our study was to determine the order in which science and health researchers read scientific papers, their reasons for doing so and the perceived difficulty and perceived importance of each section.

Study design and setting

An online survey open to science and health academics and researchers distributed via existing research networks, X (formerly Twitter), and LinkedIn.

Results

Almost 90% of respondents self-declared to be experienced in reading research papers. 98.6% of the sample read the abstract first because it provides an overview of the paper and facilitates a decision on continuing to read on or not. Seventy-five percent perceived it to be the easiest to read and 62.4% perceived it to be very important (highest rank on a 5-point Likert scale). The majority of respondents did not read a paper in the IMRAD (Introduction, Methods, Results And Discussion) format. Perceived difficulty and perceived importance influenced reading order.

Conclusion

Science and health researchers do not typically read scientific and health research papers in IMRAD format. The more important a respondent perceives a section to be, the more likely they are to read it. The easier a section is perceived, the more likely it will be read. We present recommendations to those teaching the skill of writing scientific papers and reports.
