We performed optical photometry and spectral observations of the symbiotic stars 4U1954+319 and ZZ CMi. For 4U1954+319, using high-resolution spectra, we, measure the equivalent widths of diffuse interstellar bands (DIBs) and estimate the interstellar reddening E(B-V ) = 0:83?0:09. Using the GAIA distances and our photometry, we find: (1) the absolute V -band magnitude MV =-5:23 ? 0:08 of 4U1954+319 and that the mass donor is a supergiant of luminosity class Ib, and (2) MV = -0:27?0:2 for ZZ CMi and that the mass donor is a giant of luminosity class III.
The effect of psychosocial interventions for sexual health in patients with pelvic cancer: a systematic review and meta-analysis
Authors: Ask Samuel , Schildmeijer Kristina , Kaldo Viktor , Hellström Amanda
Published: April 2024

Aim: The aim of this systematic review and meta-analysis was to explore and evaluate the effect of psychosocial interventions in improving sexual health outcomes among post-treatment patients with pelvic cancer.
Methods: Inclusion and exclusion criteria were pelvic cancer survivors; psychosocial interventions; studies with a control group and measures of sexual health. Five databases were searched for literature along with an inspection of the included studies’ reference lists to extend the search. Risk of bias was assessed with the RoB2 tool. Standardised mean difference (SMD) with a random effects model was used to determine the effect size of psychosocial interventions for sexual health in patients with pelvic cancers.
Results: Thirteen studies were included, with a total number of 1,541 participants. There was a large heterogeneity regarding the type of psychosocial intervention used with the source found in a leave one out analysis. Six studies showed statistically significant improvements in sexual health, while three showed positive but non-significant effects. The summary effect size estimate was small SMD = 0.24 (95% confidence interval [CI]: 0.05 to 0.42, p = 0.01).
Discussion: There is limited research on psychosocial interventions for sexual health in pelvic cancer patients. There are also limitations in the different pelvic cancer diagnoses examined. Commonly, the included articles examined physical function rather than the whole sexual health spectrum. The small effect sizes may in part be due to evaluation of psychosocial interventions by measuring physical dysfunction. Future research should broaden sexual health assessment tools and expand investigations to more cancer types.

Published: April 2024

Las aseguradoras juegan un papel relevante en una economía sana, ya que proveen un servicio de seguridad a bienes y personas. El mercado asegurador venezolano en las últimas décadas ha enfrentado grandes desafíos y retos en un medio estrecho, donde conocer a los competidores más cercanos es de suma importancia. El órgano rector público que regula la comparación entre las aseguradoras solo ha hecho uso de las primas cobradas como factor de categorización; sin embargo, este órgano hace pública una gama adicional de indicadores. En este estudio hacemos uso de cinco de estos indicadores, utilizados en los últimos tres años, para corroborar si las primas cobradas representan una característica única clasificatoria. El vasto repertorio del aprendizaje automático permite hacer frente al aumento significativo de variables de estudio y sus posibles agrupaciones; el análisis multivariante de estas 18 variables ha requerido del uso del método de análisis factorial, que permite reducir la dimensionalidad en factores altamente correlacionados. Con estos nuevos factores se busca agrupar-clasificar con ayuda de los algoritmos no supervisados de K-Medias (K-Means) y medias difusas (Fuzzy C-Means) comparando sus agrupaciones derivadas, cotejadas con respecto a que las primas cobradas representen una característica determinante de agrupación.

Early childhood independence is influence by habituation factors applied by parents. In general, working parents have limited time in the process of guiding and developing children’s independence. In playing it, parents who work are sometimes assisted by other parties such as grandmothers, grandfathers or nannies. But there are parents who decide to carry out this role independence of children’s independence. This research uses a qualitative approach with a case study method. The subjects of this research consisted of 3 children aged 5-6 years who both worked. This research data was obtained from observations, interviews and documentation. The results of the research showed that from the third subject there was a difference in the picture of independence. Subject R shows that he is starting to be independent, while subjects I and M are already independent. For parents who are helped by grandmothers, children appear independents. For parents who are helped by grandmothers, children appear to be more independent compared to parents who are not helped by grandmothers. Therefore, this research recommends that parents ask for help parenting if needed and have three main roles, namely as a guide, motivator and facilitator.

Authors: Rauf Rahyunir , Yuslaini Nina , Febrian Ranggi Ade , Maulidiah Sri
Published: April 2024

This study aims to examine and challenge the impact of local government policy governance on the oil palm plantation sector in Riau Province, Indonesia. It was discovered that 1,628 million hectares of illegal oil palm plantations are located within forest areas. Plantation area and crop harvest areas are declining due to the increase in damaged old plants, low productivity of plantation crops, inadequate facilities and infrastructure conditions, low technology application, plantation business licensing, limited downstream plantation industry and marketing, assistance in changing the attitudes, behavior, and skills of farmers. The methodology used was exploratory qualitative to explore this topic, and the determination of research topics was conducted using Biblioshiny application analysis. Then, the data was analyzed using Nvivo 12 Plus software. The results of this study discovered that the policy governance of the oil palm plantation sector as a leading commodity in Riau Province, Indonesia, is influenced by three dimensions: firstly, the actor dimension; secondly, the structural dimension; and third, the empirical dimension of governance. This research contributes as a knowledge reference to oil palm plantations.

Published: April 2024

Background: The aim of the present study was to evaluate whether the HMG (Hyperplasia of the Mammary Gland) effect of RuXian-I in estrogen- and progestogen- induced HMG rats is mediated through the activation of MAPK (Mitogen activated protein kinase) and NF-κB signaling pathways. Materials and methods: Fifty virgin female Wistar rats were randomly divided into in control and HMG, RuXian-I (0.75 g·kg−1, 1.5 g·kg−1, 3 g·kg−1, respectively) groups, 10 in each. Injections of estrogen and progestogen were given to establish rat models of HMG and RuXian-I at the same time. Changes in nipple heights were measured; pathologic changes of HMG in rats were also observed under a light microscope; the phosphorylation levels of MAPK and NF κB and the expression levels of TNF-α and IL-1β were measured. Results: Compared with the control group, the nipple diameters and height were increased significantly, the numbers of MG lobules were increased, there were changes in breast histopathology, the levels of TNF-α and IL-1β increased significantly, and MAPK and NF-κB were activated in HMG rats. Compared with the HMG model group, the increased nipple height was decreased, the numbers of MG lobules were reduced, the degree of HMG in rats was alleviated obviously, and the phosphorylation level of MAPK and NF-κB and cytokines TNF- α and IL-1β levels in serum were decreased by RuXian-I treatment. Conclusion: Those results suggest RuXian-I has protective and therapeutic effects on HMG rats induced by estrogen and progestogen and is likely to activate MAPK and NF-κB signaling pathways.
Thermal Expansion of Metal Oxides in Silicate Melts: A Simple Theoretical Analysis
Authors: Nesbitt H. Wayne , Richet Pascal , Henderson Grant S. , Bancroft G. Michael
Published: April 2024

The isobaric, isochemical coefficient of thermal expansion ( α) is the proportionality constant relating ∂V/V and ∂T. Noting that ∂V/V equals ∂lnV at constant pressure and composition (i.e., P and X):

α=(∂VV∂T)P,X=(∂lnV∂T)P,X

A polynomial expression for the temperature dependence of lnV yields direct and accurate calculation of α of melts and glasses. Using the approach, αG of Na-silicate glasses is shown to be constant between 300 and ∼650 K (P and X constant), but it increases linearly with Na2O content, indicating that α is controlled mostly by Na behaviour. Values of α for a melt or glass are necessarily (thermodynamically) related to the coefficients of thermal expansion of its ‘N’ melt components ( αN) by:

α=α1θ1+α2θ2+α3θ3+⋯+αNθN

where θ represents volume fraction of a component. Calculated αNa2O and αSiO2 values compare satisfactorily with reported values for melts containing ∼40–60 mole% Na2O but are less satisfactory for highly siliceous melts, implying need for refinement of α values.

The Coulombic force of attraction between cation and anion is the primary determinant of the magnitude of α values of alkali and alkaline earths oxides. Their values represent a lower bound on α of 3d and 4f modifier oxides. Values larger than this lower bound likely result from a change in coordination number (CN) from higher to lower CN values of modifier cations. Experimental and molecular dynamics studies indicate that partial charges on NBO (O of Si-O-M moieties) and BO (O of Si-O-Si moieties) are about −0.96 and −0.64 respectively, thus NBOs should be incorporated into the first coordination spheres of modifier cations in preference to BOs. A simple mechanism is proposed whereby NBO-BO exchange occurs and CN of the modifier cation decreases with minimal topological adjustment or energetic cost to the melt.

Published: April 2024

In response to the steady rise in global demand for energy resources such as gas and oil, there is a pressing need to enhance the efficiency and safety of pipeline transportation systems. These systems, integral for transferring vast amounts of energy, must operate under increasingly higher pressures and larger diameters without compromising reliability. This study focuses on utilizing finite element analysis (FEA) to investigate the influence of crack orientation and the presence of defects on the fatigue life of pipelines. By simulating internal pressure scenarios and examining various defect characteristics with the AFGROW software, this research applies damage tolerance principles to offer insights into the fatigue behavior of pipelines. The findings can be applied to extend the operational life and ensure the integrity of these critical infrastructures, thereby supporting the sustainable and safe transport of energy resources.
Using Own Algorithms to Increase the Quality and Fatigue Resistance of FDM Printing for Use in Drones and Small Aircraft
Authors: Szafran Krzysztof Stanisław , Jeziorek Łukasz Andrzej
Published: April 2024

The present article discusses the three-dimensional (3D) printing process in the fused deposition modeling (FDM) or the fused filament fabrication (FFF) technique using the author’s own philosophy of shaping the printing head path. The main requirements are the possibility of eliminating supports and reducing or even eliminating the need for the mechanical processing of 3D prints before their final assembly. The presented methodology was implemented in a computer program written by the author and was used to print typical parts used in aviation. Individual methods of shaping parts typical for the construction of small flying models, such as wings and fuselages, and methods of strengthening and connecting them have been discussed. The proposed solutions are illustrated with photos of readymade prints. This article also discusses the issues that printing high-quality parts may encounter and how to avoid them. Some attention has also been paid to the materials used for printing and their suitability in the construction of aircraft and their fatigue strength.
Frost hardiness of flower buds of 16 apricot cultivars during dormancy
Authors: Bakos József L. , Ladányi Márta , Szalay László
Published: April 2024

The effectiveness of apricot cultivation is greatly threatened by frost damage to flower buds during the dormancy period. One of the most important aspects of the evaluation of cultivars is therefore the determination of their frost tolerance. In this paper, the frost hardiness of flower buds of 16 apricot cultivars was investigated in three dormancy periods, applying a standardised artificial freezing test protocol and determining LT50 values. The results showed that both the genotypes and the yearly climatic conditions had a significant effect on frost tolerance. A genotype generally determines the potential maximum of its frost tolerance (‘Sweet Red’ and ‘Primaya’ were very sensitive to frost every year, while ‘Harlayne’ and ‘Rózskajszi C.1406’ could be considered as frost hardy). Flower buds can reach different levels of frost resistance each year depending on the temperature conditions during the hardening and dehardening periods. From the point of view of yield security, it is essential when planning an orchard, to take into account and harmonise the frost hardiness of the cultivars selected and the growing site conditions. Therefore, it is very important to have adequate information about the frost hardiness of different apricot cultivars, which should be included in cultivar descriptions. This paper is intended to contribute to this goal.
O absoluto fenomenológico
Authors: Barbaras Renaud
Published: April 2024

The same subjectivity that makes the world appear belongs, as an integral part, to that which it makes appear, so that there is no alternative between the phenomenological involvement of the world by subjectivity and the ontological involvement of subjectivity by the world. These are the two faces, already abstract, of a fundamental and original situation, in other words, a primitive fact or an archifact. We have thus transported the correlation to the terrain of the world in the form of a double position of the subject, which I have further formulated metaphorically through the distinction between being before and being within. So, what does it mean to belong to the world, or rather, what are the senses of belonging implied by the fundamental situation we have just described?
The Other of Correlation (Small Prolegomena to any Future Phenomenological Metaphysics)
Authors: Jean Grégori
Published: April 2024

The recent liberation of phenomenology’s “metaphysical” word seems to us to present a twofold risk: on the one hand, that of leading us to lose in intension what they will have made us gain in extension - what exactly does the term “metaphysical” mean here, and can we even hope to provide an exact definition? On the other hand, it would convert our former reservations, which may indeed have been excessive, into a temerity that would ultimately be no less so. The aim we have set ourselves here must therefore be modest: to attempt to avert this twofold risk by first equipping ourselves with a clear and unambiguous concept of what is or could legitimately be understood by the term “phenomenological metaphysics; to show then how and why phenomenology, rightly or wrongly, but without really realizing what was preventing it from doing so, has never really managed to do so; to indicate finally the question that a “phenomenological metaphysics” conforming to its concept would have to ask, and to which it would have to commit itself to answer.
Primary ciliary dyskinesia diagnosis management in low-resource setting, a practical approach
Authors: Dumitroae Andreea , Voropanov Ion Alexandru , Slăvulete Ramona Elena , Comănici Valentina-Daniela , Craiu Mihai , Stan Iustina Violeta
Published: April 2024

Primary ciliary dyskinesia (PCD) is a congenital disorder with genetic determinism, characterized by chronic infections of the upper and lower respiratory tract. The triad of situs inversus, chronic sinusitis and bronchiectasis is called Kartagener Syndrome. PCD is a predominantly autosomal recessive disease, involving more than 40 mutations of genes. Abnormal cilia movement leads to defective mucociliary clearance resulting in chronic cough, nasal congestion, recurrent otitis, chronic sinusitis, male infertility and other rare conditions. First presented case is one of a 17-year-old girl with chronic treatment for asthma for the last 5 years. Respiratory functional tests were performed: the patient didn’t present variable airflow obstruction. The diagnosis of PCD was suspected because of chronic respiratory infections in a situs-inversus patient. The second case is a 4-year-old patient with a clinical history highly suggestive of ciliary dyskinesia, who received a recommendation for genetic testing to confirm the diagnosis. The third case is an 8-year-old boy with wet cough from neonatal period, bronchiectasis and sinusitis. Both his symptoms and the fact that his adult brother presented situs inversus, chronic sinusitis and bronchiectasis led us to raise suspicion of PCD. These case reports aim to highlight the real-life difficulties in a rather low-resource setting in diagnosing PCD, a genetic syndrome with long term impact on airways. The second objective was outlining the clinical manifestations that are highly suggestive of PCD and also to develop a diagnostic algorithm for a real-life scenario involving a pulmonologist with reduced access to high-performance tools like TEM (transmission electron microscopy) and complex genetic tests. Because not all PCD cases have known genetic mutations and some don’t have ultrastructural abnormalities we could still rely on the old saccharin test in order to select patients that are candidates for nasal NO. A high index of suspicion for PCD should be present in any patient with non-cystic fibrosis bronchiectasis patient. PCD remains a rare and underdiagnosed genetic syndrome in real-life paediatric setting in countries with limited neonatal screening programs. Increasing awareness of this condition and accessible diagnostic tools are desirable in order to find patients with high-likelihood of PCD and to refer these selected patients to specialized centres. Authors provide an age-dependent approach of PCD patients in a low resource setting.

Authors: Mosteanu Ioana-Madalina , Iorga Luiza-Ana , Mahler Beatrice
Published: April 2024

Lung cancer ranks among the first in terms of mortality rates in the world, which is why a screening program for people at risk is imperative. However, nowadays, thanks to new diagnostic technologies and oncological therapies, lung cancer has maybe come to be classified as a chronic disease. Low-dose computer tomography is currently the best method for lung cancer screening, and the screening criteria are already established internationally. Very important is the psychological or therapeutical support given to patients in the attempt to quit smoking, as well as other methods of prevention and combating pollution.
UV Irradiated SiO2 Nanoparticles as Insulin and Immunoglobulin Molecule Carriers
Authors: Dekhtyar Yuri , Gorohovs Marks , Dimitrova Todorka , Sorokins Hermanis
Published: April 2024

Insulin and immunoglobulin therapy is commonly administered through injections that are invasive and painful. They cannot be taken orally because digestive enzymes break them down. To protect against enzymes, drug molecules may be “packed”, which decreases interaction of the active surface of the molecule with the environment. Silica nanoparticles (SiO2) may be used to attach proteins like insulin or immunoglobulin for use in drug delivery. They are stable and biocompatible. Exposing SiO2 nanoparticles to UV radiation may control molecule–nanoparticle attachment because of their electrostatic interactions. This study demonstrates the influence of UV radiation of SiO2 nanoparticles on insulin and immunoglobulin molecule attachment. Alteration of the surface electric potential of SiO2 nanoparticles by UV radiation was determined using electron work function measurements. Influence of radiation on formation of molecule-nanoparticle complexes was assessed by spectrophotometry of their sedimentation rate in solution. Increasing UV exposure time negatively charges the surfaces of SiO2 nanoparticles. Insulin exhibits better adsorption with SiO2 nanoparticles compared to immunoglobulin, likely due to favourable conditions promoting attractive electrostatic interactions. Longer UV exposure weakens insulin adsorption but does not significantly affect immunoglobulin adsorption.

Jan Łukasiewicz and His German Ally. A History of Łukasiewicz-Scholz Cooperation and Friendship
Authors: Brożek Anna
Published: April 2024

The article presents interpersonal relations and mutual influences between German logician Heinrich Scholz and Polish scholars, first of all Jan Łukasiewicz. The background for presenting these relationships consists of reflections on the development of logic in Poland and various conceptions of how to apply logic to philosophical issues. Firstly, Jan Łukasiewicz’s program of logicisation of philosophy and his search for allies is presented. Secondly, the forms of cooperation between Łukasiewicz and Scholz, as well as contacts between the latter and other Polish scholars are sketched. Finally, forms of Scholz’s help to Polish friends during the tumultuous period of World War II are examined. The article provides also some reflections on the approach to logic in various European centers of analytic philosophy and historical comments on the continuity of philosophical and logical schools.
How Law’s Nature Influences Law’s Logic
Authors: Hage Jaap
Published: April 2024

Classical logic is based on an underlying view of the world, according to which there are elementary facts and compound facts, which are logical combinations of these elementary facts. Sentences are true if they correspond to, in last instance, the elementary facts in the world. This world view has no place for rules, which exist as individuals in the world, and which create relations between the most elementary facts. As a result, classical logic is not suitable to deal with rules, and is therefore unsuitable to deal with legal reasoning. A logic that is more suitable should take into account that law is a part of social reality, in particular a part that consists of constructivist facts, and that rules play a central role in law. This article gives a superficial description of how social reality exists and of the place of law and legal rules in it. It uses this description to argue that traditional techniques to reason with and about legal rules provide a better logic for law than classical logic. These techniques can be accommodated in a logic that treats rules as logical individuals.
Legal Reasoning and Logic
Authors: Woleński Jan
Published: April 2024

This paper investigates the basis arguments of so-called legal logic and their relation to logic in its standard meaning. There is no doubt that legal arguments belong to logic in the wide sense (sensu largo), but their reduction to schemes of formal logic (logica sensu stricto) is a controversial issue. It can be demonstrated that only some legal arguments fall under explicit rules of formal logic, that is, having a deductive character. Most such reasoning is fallible, and its correctness depends on appealing to extra-logical principles taken from legal norms. For instance, if we say, “If it is permitted more, then it is permitted less” (argumentum a maiori ad minus), we assume that the concepts expressed by the words “more” and “less” are already defined.
Legal Gaps and their Logical Forms
Authors: Barbosa Matheus Gabriel , Schang Fabien
Published: April 2024

The concept of legal gap is tackled from a number of logical perspectives and semantic methods. After presenting our own goal (Section 1), a first introduction into legal logic refers to Bobbio’s works and his formalization of legal statements (Sections 2 and 3). Then Woleński’s contribution to the area is taken into account through his reference to the distinction between two juridical systems (viz. Common Law vs Civil Law) and the notion of conditional norms (Section 4). The notion of reason is also highlighted in the case of Raz’s legal logic, thereby leading to a future connection with von Wright’s logic of truth and an analogy made with an anti-realist reading of truth-values and norms (Section 5). Our personal contribution is introduced through a reflection on how logic should deal with the logical form of norms (Section 6), before entering a number of crucial definitions and distinctions for the concepts of norm, legal statement, and promulgation (Section 7). The final point is a proposed semantics for legal statements, which is both many-valued and gap-friendly (Section 8). A distinction between a number of requirements for permission and forbiddance leads to a set of non-classical juridical systems in which non-permission and forbiddance are not equivalent with each other any more; this does justice to Woleński’s former distinction between Common Law and Civil Law, also leading ultimately to a non-classical square of legal oppositions in which several legal operators may collapse into other ones (Section 9).
Perspectives of Perceived Organizational Support (POS) Theory Towards Individual Happiness
Authors: Sam Thoong Hai , Isa Khairunesa , Palpanadan Sarala Thulasi
Published: April 2024

Introduction: Organizations must take a proactive stance when it comes to their workers' welfare and well-being to demonstrate their best commitment in this regard.
 
Objective: This paper presents the descriptive data of organizational factors that contribute to staff happiness in one of the Malaysian Technical University Network (MTUN) clusters in Malaysia.
 
Methods: This study was conducted at one of the Malaysian Technical University Network (MTUN) clusters in Malaysia. It involved 20 respondents comprising academicians who had served more than 11 years. The session at the Round Table Discussion was organized to discuss the issues that were highlighted in the survey data.
 
Results and Conclusion: Analysis showed that the personal economy and personal appreciation dimension were among the highest contributors in determining employee happiness, followed by a support system, workstation environment, and trust. Furthermore, the discussion is related to the general aspect of Perceived Organizational Support Theory which supports the data analysis on individual happiness aspect in the institution of higher education. 
 
Originality/Value: By emphasizing the role of factors such as support systems, workstation environment, and trust in determining employee happiness, the study provides valuable insights into the broader dynamics of the workplace. Understanding how these factors influence employee satisfaction can inform strategies for improving organizational culture and employee engagement. Hence, this finding is related to Sustainable Development Goal (SDG) 3: Good Health and Well-being because it focuses on individual happiness, which is closely tied to mental well-being and overall health, both of which are central to SDG 3.
Predicting Eco-labeled Product Buying Behavior in an Emerging Economy through an Extension of Theory of Planned Behavior
Authors: Alam Syed Shah , Ho Yi-Hui , Ahmed Saif , Lin Chieh-Yu
Published: April 2024

Purpose: This research attempts to explore the determinants of eco-labeled product buying behavior by extending the theory of planned behavior (TPB).
 
Theoretical framework: To build a comprehensive predicting model, environmental knowledge, perceived value, environmental concern, product knowledge, self-efficacy, consumer guilt, and eco-labeling are added to the traditional TPB.
 
Method: The proposed conceptual model was tested by conducting a questionnaire survey on consumers in an emerging economy. The partial least square-based structural equation modeling was used to analyze the data.
 
Results and conclusion: The results showed that product knowledge moderates the relationship between subjective norms and eco-labeled product buying intention. The results also reveal that attitude, perceived behavioral control, and subjective norm mediate the association between environmental concern and eco-labeled product buying intention. In addition to TPB constructs, consumer guilt, eco-labeling, perceived value, self-efficacy, and environmental knowledge significantly affect buying intention.
 
Originality/value: The current research addresses the research gap by empirically examining the in-depth effects, and the underlying mechanism of eco-label informed green purchase and its acceptance in Malaysian perspectives.
"Not Just a Double-O": Shifting Embodiments of Female Heroism in No Time to Die
Authors: Kassab Maryline
Published: April 2024

Like the spiralling title credits of Casino Royale (2006), the representation of women in Bond films has not always followed a linear path. The evolution of female characters has generally been viewed as peaking in the Brosnan-era with the introduction of a stern female M (Judi Dench) in GoldenEye (1995) and the highly skilled Agent Lin (Michelle Yeoh) in Tomorrow Never Dies (1997). Craig-era films continued to cast Dench, but by SkyFall’s release (2012), M was discarded, and, barring a few exceptions, female representation of Agent Lin’s caliber was replaced with disposable anti-heroines such as Severine (Berenice Marlohe). This article reassesses Craig-era Bond women, specifically in No Time To Die (2021) by focussing on the shifting nature of their embodiment. The depiction of these Bond women and their various lived experiences of womanhood have profound implications for the continuation of the series. The article argues that these female protagonists re-envision the Bond heroine so to as align with feminist movements (such as #MeToo) and themes. Drawing from feminist-phenomenological frameworks rooted in sensory scholarship and Beauvoirean philosophy, this article looks back at previous examples of prominent female spies in the Bond films to determine how the latest film instalment recycles and re-imagines the female action heroine through the body. Loaded with power and independence, these new protagonists function not just as female Double-O's but agentic cinematic characters in their own right.
Fiona Volpe: A New Perspective on James Bond's Iconic Femme Fatale
Authors: Mason Shana
Published: April 2024

While narratives of gender politics and female identity in Western visual culture have become more dynamic with the passage of time, one of the most contentious spheres of discussion in mass media surrounds that of Ian Fleming’s ultimate fictional creation, James Bond. Female sexuality and gender politics in the Bond universe has been robustly, and rightfully, scrutinised by academic and casual spectators for at least 50 of the 70 years since his inception. Yet, one of the most enduring characters in the cinematic canon has not yet been given this discerning treatment, in earnest. Originally called "Fiona Kelly" by screenwriters Richard Maibaum and John Hopkins, Fiona Volpe was portrayed by Italian actress Luciana Paluzzi-Solomon in Terence Young’s 1965 film adaptation of Thunderball. In November 2017, I had the opportunity to interview Mrs. Paluzzi-Solomon for a now-abandoned book concept. As one of the few actresses from the Sean Connery-era who are still living, she was remarkably forthcoming regarding her professional and personal experiences on set. Without pride or prejudice, Mrs. Paluzzi-Solomon’s account proved to be not only to be illuminating in and of itself as an interview, but also served as a foundation to better understand the origins, development, and public reception of the gold standard femme fatale of the Bond films. This article will explore the character of Fiona Volpe, her origins, plot function, and legacy, from the unique perspective of the woman who brought her to life.
Multiple Encounters: Queer Migrants and Bureaucratic Violence
Authors: Lins França Isadora , Ribeiro Ferreira Bruno
Published: April 2024

In this paper, we analyze the multiple encounters queer asylum seekers face due to violence embedded in border control and asylum recognition processes. This analysis is based on the reconstitution of two narratives that form part of an ethnographic study, the result of five years of fieldwork with queer migrants in Brazil and Spain. We employ the notion of bureaucratic violence to understand the ambiguities between control and protection in the emergence of the LGBTI refugee as a subject of rights in the humanitarian realm.
Navigating the Social Turn
Authors: Rambiritch Avasha
Published: April 2024

This paper will begin by highlighting how five major social turns in South Africa’s history have impacted issues of space and safety in the South African writing centre. The paper will attempt to define the concepts of space and safety through a social justice lens alongside the philosophy of ubuntu pedagogy. Embracing philosophy’s from the Global South allows us to juxtapose indigenous and western knowledge systems  without privileging one while marginalising the other, thus putting an end to epistemic injustices that devalue indigenous knowledge systems such as Ubuntu (Ngubane & Makua, 2021). Crucial to the interrogation of issues of space and safety is a close reading of the ways in which the writing centre space has been theorised and metaphored, reflecting the evolution of the writing centre. Close interrogation will demonstrates how such metaphors conflict with the space of the South African writing centre. The last part of this paper proposes the reimagining of the writing centre space, allowing us to reinvent the space  of the writing centre, into one that is  vibrant and brave. Importantly, it hopes to propose that such reimagining may allow writing centres to move from margin to centre.

Satınalma gücü paritesinin geçerliliği: E-7 ülkeleri örneği (1992-2022)
Authors: Turgut Ecem , Uçan Okyay
Published: April 2024

Uluslararası ekonomi teorilerindeki en önemli konulardan biri, satınalma gücü paritesinin döviz kuru belirleme modelleri içerisinde yer alıp almadığıdır. Bu çalışmada da özellikle E-7 (Brezilya, Çin, Endonezya, Hindistan, Meksika, Rusya, Türkiye) ülkelerinde satınalma gücü paritesinin geçerli olup olmadığının incelenmesi amaçlanmıştır. Çalışmada söz konusu ülkelerin 1992-2022 dönemi verilerinden yararlanılmıştır. Yapılan ekonometrik inceleme sonucunda yatay kesitin bağımlı olduğu ve homojenlik varsayımı kabul edilmiştir. Bundan dolayı değişkenlerin durağan olduğu seviyenin tespit edilmesinde Bootstrap Hadri ikinci nesil birim kök testinden yararlanılmış ve değişkenlerin birinci farkında durağan olduğu anlaşılmıştır. Bundan dolayı değişkenler arasındaki eşbütünleşme ilişkisinin tespit edilmesinde ikinci nesil bir eşbütünleşme testi olan ve yatay kesit bağımlılığı altında çalışan Westerlund ECM testinden yararlanılmıştır. İnceleme sonucunda nominal döviz kuru ile yurtiçi fiyat seviyesinin yurtdışı fiyat seviyesi olan oranı arasındaki ilişkinin olumlu yönde olduğu yani değişkenler arasında eşbütünleşme ilişkisi olduğu tespit edilmiştir. Böylelikle bu çalışmada E-7 ülkelerinde satınalma gücü paritesinin geçerli olduğu kabul edilmiştir.

Mini Review: Scientific Analysis of Radical S-Adenosylmethionine (SAM) Enzymes
Authors: Ariyaratne Gallage H. D. N.
Published: April 2024

The radical S-Adenosylmethionine (SAM) superfamily of enzymes catalyzes a diverse range of reactions ranging from hydrogen abstraction to complicated multistep reactions such as insertions and rearrangements. The reactions they catalyze are utilized in a broad range of biological functions such as cofactor and natural product biosynthesis, DNA repair, tRNA modification, metalloproteinase cluster formation, lipid metabolism and post-transcriptional and post-translational modifications. Sealed topographies of the radical SAM superfamily include a CXXXCXXC (CX3CX2C) motif that binds a [Fe4S4] cluster essential for the reductive cleavage of SAM. This is a review of recent developments in my understanding of the structure and mechanisms of these enzymes that, I gained through the research experience at Broderick’s group at Montana State University. I am currently affiliated with Mayo Clinic’s Physiology and Biomedical Engineering department as a predoctoral student.
Quantitative reagent monitoring in paper-based electrochemical rapid diagnostic tests
Authors: Bezinge Léonard , deMello Andrew J. , Shih Chih-Jen , Richards Daniel Ashley
Published: April 2024

Paper-based rapid diagnostic tests (RDTs) are an essential component of modern healthcare, particularly for the management of infectious diseases. Despite their utility, these capillary-driven RDTs are compromised by high failure rates, primarily caused by user error. This limits their utility in complex assays that require multiple user operations. Here, we demonstrate how this issue can be directly addressed through continuous electrochemical monitoring of reagent flow inside an RDT using embedded graphenized electrodes. Our method relies on applying short voltage pulses and measuring variations in capacitive discharge currents to precisely determine the flow times of injected samples and reagents. This information is reported to the user, guiding them through the testing process, highlighting failure cases and ultimately decreasing errors. Significantly, the same electrodes can be used to quantify electrochemical signals from immunoassays, providing an integrated solution for both monitoring assays and reporting results. We demonstrate the applicability of this approach in a serology test for the detection of anti-SARS-CoV-2 IgG in clinical serum samples. This method paves the way towards “smart” RDTs able to continuously monitor the testing process and improve the robustness of point-of-care diagnostics.
Diffusion Mechanisms and Preferential Dynamics of Promoter Molecules in ZSM-5 Zeolite

Published: April 2024

The diffusion in ZSM-5 zeolite of methanol and of two series of promoters of the methanol to dimethyl ether reaction (linear methyl esters, benzaldehyde, 4-n-alkyl benzaldehydes) has been studied using classical molecular dynamics in the NVT ensemble. Whereas promoter diffusion coefficients decrease with increasing alkyl chain length in methyl esters, the aromatic aldehyde promoters all have similar diffusion coefficients. The lowest diffusion coefficient is that of benzaldehyde. All the promoters exhibit a preference for moving in the straight pore, a preference that is most pronounced for the 4-n-alkyl benzaldehydes and least for the longest aliphatic esters. A novel diffusion mechanism, a molecular ’3-point turn’, is observed. The diffusion coefficient of methanol is larger than that of all the promoters. The more catalytically active aromatic aldehyde promoters limit methanol diffusion less than the aliphatic esters.

Chagas disease is caused by the parasite Trypanosoma cruzi and affects over 7 million people worldwide. The two actual treatments, Benznidazole (Bzn) and Nifurtimox, cause serious side effects due to their high toxicity leading to treatment abandonment by the patients. In this work, we propose DNA G-quadruplexes (G4) as potential therapeutic targets for this infectious disease. We have found 174 putative quadruplex forming sequences per 100,000 nucleotides in the genome of T. cruzi and confirmed G4 formation of three frequent motifs. We synthesized a family of 14 quadruplex ligands based in the dithienylethene (DTE) scaffold and demonstrated their binding to these identified G4 sequences. Several DTE derivatives exhibited micromolar activity against epimastigotes of four different strains of T. cruzi, in the same concentration range as Bzn. Compounds 3 and 4 presented remarkable activity against trypomastigotes, the active form in blood, of T. cruzi SOL strain (IC50 = 1.5-3.3 μM, SI =25-40.9), being around 40 times more active than Bzn and displaying much better selectivity indexes.
