Authors: Mayer-Trzaskowska Paulina , Robakowska Mariola , Gierz Łukasz , Pach Joanna , Mazur Ewa
Published: December 2023

In this study, polyurethane/polyurea coatings were exposed to four different types of aging: aging in the natural environment (NC), accelerated ultraviolet aging (UV), aging in a sodium chloride solution (NaCl), and thermal aging (TC). To monitor the changes that occurred during these processes, the thickness was measured and microscopic and macroscopic observations were conducted continuously. The samples aged under various conditions were then subjected to spectroscopic (FTIR) and thermal (TGA) analysis to determine the possible structural changes in the coatings. The dependence of aging conditions on the physicochemical properties of the tested coating surfaces was thoroughly investigated and characterized by the water contact angle and surface free energy. Adhesion tests were performed after the established aging period. The results show that different aging conditions have a tremendous effect on the appearance and pull-off strength. The coatings that age in a NaCl solution are more affected in terms of their adhesion.

Published: December 2023

The features or actuation behaviors of nature’s creatures provide concepts for the development of biomimetic soft bioactuators/robots with stimuli-responsive capabilities, design convenience, and environmental adaptivity in various fields. Mimosa pudica is a mechanically responsive plant that can convert pressure to the motion of leaves. When the leaves receive pressure, the occurrence of asymmetric turgor in the extensor and flexor sides of the pulvinus from redistributing the water in the pulvinus causes the bending of the pulvinus. Inspired by the actuation of Mimosa pudica, designing soft bioactuators can convert external stimulations to driving forces for the actuation of constructs which has been receiving increased attention and has potential applications in many fields. 4D printing technology has emerged as a new strategy for creating versatile soft bioactuators/robots by integrating printing technologies with stimuli-responsive materials. In this study, we developed a hybrid ink by combining gelatin methacryloyl (GelMA) polymers with iron oxide nanoparticles (IONs). This hybrid ION-GelMA ink exhibits tunable rheology, controllable mechanical properties, magnetic-responsive behaviors, and printability by integrating the internal metal ion-polymeric chain interactions and photo-crosslinking chemistries. This design offers the inks a dual crosslink mechanism combining the advantages of photocrosslinking and ionic crosslinking to rapidly form the construct within 60 s of UV exposure time. In addition, the magnetic-responsive actuation of ION-GelMA constructs can be regulated by different ION concentrations (0–10%). Furthermore, we used the ION-GelMA inks to fabricate a Mimosa pudica-like soft bioactuator through a mold casting method and a direct-ink-writing (DIW) printing technology. Obviously, the pinnule leaf structure of printed constructs presents a continuous reversible shape transformation in an air phase without any liquid as a medium, which can mimic the motion characteristics of natural creatures. At the same time, compared to the model casting process, the DIW printed bioactuators show a more refined and biomimetic transformation shape that closely resembles the movement of the pinnule leaf of Mimosa pudica in response to stimulation. Overall, this study indicates the proof of concept and the potential prospect of magnetic-responsive ION-GelMA inks for the rapid prototyping of biomimetic soft bioactuators/robots with untethered non-contact magneto-actuations.

Published: December 2023

Air, a widely recognized dielectric material, is employed as a dielectric layer in this study. We present a triboelectric sensor with a laser-induced graphene (LIG) electrode and an air-trapped pad using silicone rubber (SR). A very thin device with a thickness of 1 mm and an effective gap for contact–separation between the films of silicone rubber and polyimide (PI) of 0.6 mm makes the device extremely highly sensitive for very low amplitudes of pressure. The fabrication of LIG as an electrode material on the surface of PI is the key reason for the fabrication of the thin sensor. In this study, we showed that the fabricated air-trapped padded sensor (ATPS) has the capability to generate an output voltage of ~32 V, a short-circuit current of 1.2 µA, and attain a maximum power density of 139.8 mW m−2. The performance of the ATPS was compared with a replicated device having a hole on the pad, allowing air to pass through during contact–separation. The observed degradation in the electrical output suggests that the trapped air in the pad plays a crucial role in enhancing the output voltage. Therefore, the ATPS emerges as an ultra-sensitive sensor for healthcare sensing applications.

Published: December 2023

As a substitute for conventional polymers for the preparation of biodegradable microcellular polymeric foams, polybutylene succinate (PBS) presents one of the most promising alternatives. However, the low melt strength of PBS makes it difficult to produce high-performance microcellular foams. This study aimed to improve the melt strength of PBS and explore the mechanical, thermal, crystalline, rheological, and supercritical CO2 foaming properties of PBS nanocomposites by using carbon nanofibers (CNFs). This study found that nanocomposites containing 7 wt% CNF exhibited the highest tensile strength, Young’s modulus, and bending strength. Moreover, the CNF nanofillers were well dispersed in the PBS matrix without significant agglomeration, even at high filler concentrations. Furthermore, the nanocomposites demonstrated improved melting temperature and crystallinity compared with pure PBS. The rheological analysis showed that the addition of CNFs significantly increased PBS viscosity at low frequencies due to the interaction between the PBS molecular chains and CNFs and the entanglement of CNFs, resulting in a more complete physical network formation when the CNF content reached above 3 wt%. During the supercritical CO2 foaming process, the addition of CNFs resulted in increased cell density, smaller cells, and thicker cell walls, with good laps formed between the fibers on the cell walls of nanocomposite foams. Moreover, the electrical conductivity and electromagnetic interference (EMI) shielding properties of the foamed material were studied, and a nanocomposite foam containing 7 wt% CNF showed good electrical conductivity (4.5 × 10−3 S/m) and specific EMI shielding effectiveness (EMI SE) (34.7 dB/g·cm−1). Additionally, the nanocomposite foam with 7 wt% CNF also exhibited good compression properties (21.7 MPa). Overall, this work has successfully developed a high-performance, multifunctional PBS-based nanocomposite foam, making it suitable for applications in various fields.

Published: December 2023

Distillation is significantly influenced by energy costs, prompting a need to explore effective strategies for reducing energy consumption. Among these, heat integration is a key approach, but evaluating its efficiency is paramount. Therefore, this study presents exergy as an energy quality indicator, analyzing irreversibility and efficiencies in tetrahydrofuran/water and acetone/chloroform distillations. Both systems have equimolar feed streams, yielding products with 99.99 mol% purity. The simulations are performed using Aspen Plus™, enabling evaluation at the column level, as a standalone process, or from a lean perspective that considers integration opportunities with other plants. The results show that, despite anticipated energy savings from heat integration, economic viability depends on pressure sensitivity. The results demonstrate that heat-integrated extractive distillation for acetone/chloroform raises utility energy consumption. Exergy calculations comparing standalone and total site integration reveal the variation in distillation efficiency with operation mode. Global exergy efficiency in both extractive and pressure-swing distillation depends on the fate of condenser duty. In heat-integrated extractive distillation, global exergy efficiency drops from 8.7% to 5.7% for tetrahydrofuran/water and 11.5% to 8.3% for acetone/chloroform. Similarly, heat-integrated pressure-swing distillation sees global exergy efficiency decrease from 34.2% to 23.7% for tetrahydrofuran/water and 9.5% to 3.6% for acetone/chloroform, underscoring the nuanced impact of heat integration, urging careful process design consideration.

Published: December 2023

This paper presents a detailed analysis of the relation between physical characteristics and defects of green coffee beans and the sensory profile that influence the sensory notes of fragrance, aroma, flavor, and aftertaste of coffee. Machine learning models were used to identify the variables of importance and identify the ways in which these variables affect the sensory note of coffee, to determine which algorithm and its hyperparameters have greater precision in determining the sensory values of coffee such as floral, fruity, herbal, nutty, caramel, chocolate, spicy, resinous, pyrolytic, earthy, fermented, and phenolic. The result indicates the relationship and importance that exist between the physical variables, defects, and size of the green coffee bean, with respect to their respective sensory notes. The data of the proposed system demonstrate that by combining the scores of several experts, a precision can be achieved analogously to that obtained by cupping experts; therefore, the possibility of errors induced by human concerns such as fatigue or subjectivity is reduced.
Deceptive Debauchery: Secret Marriage and the Challenge of Legalism in Muslim-Minority Communities
Authors: Sheibani Mariam
Published: December 2023

“Secret Marriage” is a category accommodating a range of arrangements that seek to conceal a marital union, typically from an existing spouse, the family of the bride or groom, a segment of the community, or the state. These contentious unions have seen an upsurge in recent times in Muslim-majority countries, and, more recently, in minority-Muslim communities in the West. This essay examines the phenomenon in minority communities using three interrelated lenses of analysis: the legal, the moral, and the socio-institutional. Taking this multi-faceted approach, in this essay, I first examine the legal doctrines of the four Sunni schools of law on the requirement of publicity and witness testimony in marriage before situating that legal discussion about contractual validity within a comprehensive analysis of the broader moral and religious legitimacy of entering into a secret union. I argue that while jurists stipulate disparate minimums for contractual validity, nearly all secret marriage arrangements are nonetheless considered invalid (fāsid), meaning they are incorrectly conducted by failing to meet the required conditions for the contract to produce its legal effects (ṣiḥḥa) and are also prohibited (ḥarām) in themselves or for their entailments, meaning contracting such a marriage is sinful and entails punishment. As I show, even as some jurists may make arguments that may seem to imply that some versions of secret marriage meet the basic conditions to make them technically valid, these same jurists nonetheless argue that such marriages are immoral, religiously deficient, unbecoming of a Muslim, and little more than a pretext for illicit sex. Apart from the theoretical question of whether a secret marriage meets the conditions of contractual validity, parties to a secret marriage in Muslim communities today further engage in a number of sins and transgressions and cause harms to spouses, children, parents, extended family, and the community that must also be reckoned with. The essay concludes with recommendations for how religious authorities can take steps towards regulating marriage in minority-Muslim communities, highlighting the need for public education on Muslim marriage practices that is embedded in a deeper religious morality centering the Sunna to counteract the dominant legalism in the Muslim community that underlies numerous contemporary dilemmas.
Part2Point: A Part-Oriented Point Cloud Reconstruction Framework
Authors: Feng Yu-Cheng , Zeng Sheng-Yun , Liang Tyng-Yeu
Published: December 2023

Three-dimensional object modeling is necessary for developing virtual and augmented reality applications. Traditionally, application engineers must manually use art software to edit object shapes or exploit LIDAR to scan physical objects for constructing 3D models. This is very time-consuming and costly work. Fortunately, GPU recently provided a cost-effective solution for massive data computation. With GPU support, many studies have proposed 3D model generators based on different learning architectures, which can automatically convert 2D object pictures into 3D object models with good performance. However, as the demand for model resolution increases, the required computing time and memory space increase as significantly as the parameters of the learning architecture, which seriously degrades the efficiency of 3D model construction and the feasibility of resolution improvement. To resolve this problem, this paper proposes a part-oriented point cloud reconstruction framework called Part2Point. This framework segments the object’s parts, reconstructs the point cloud for individual object parts, and combines the part point clouds into the complete object point cloud. Therefore, it can reduce the number of learning network parameters at the exact resolution, effectively minimizing the calculation time cost and the required memory space. Moreover, it can improve the resolution of the reconstructed point cloud so that the reconstructed model can present more details of object parts.

Published: December 2023

Biomarkers are vital in healthcare as they provide valuable insights into disease diagnosis, prognosis, treatment response, and personalized medicine. They serve as objective indicators, enabling early detection and intervention, leading to improved patient outcomes and reduced costs. Biomarkers also guide treatment decisions by predicting disease outcomes and facilitating individualized treatment plans. They play a role in monitoring disease progression, adjusting treatments, and detecting early signs of recurrence. Furthermore, biomarkers enhance drug development and clinical trials by identifying suitable patients and accelerating the approval process. In this review paper, we described a variety of biomarkers applicable for cancer detection and diagnosis, such as imaging-based diagnosis (CT, SPECT, MRI, and PET), blood-based biomarkers (proteins, genes, mRNA, and peptides), cell imaging-based diagnosis (needle biopsy and CTC), tissue imaging-based diagnosis (IHC), and genetic-based biomarkers (RNAseq, scRNAseq, and spatial transcriptomics).

Published: December 2023

This is the first study aiming to enrich momilactones A (MA) and B (MB) and phenolic compounds in germinated brown rice (GBR) and non-GBR var. Koshihikari and Milky Queen through the cooking process. Extraction methods for these compounds were optimized by applying various conditions, including solvents (80% methanol and 80% ethanol), heat (80 °C), and sonication (2 h). Momilactone and phenolic quantities were determined by ultra-performance liquid chromatography–electrospray ionization mass spectrometry (UPLC–ESI-MS) and high-performance liquid chromatography (HPLC), respectively. Accordingly, cooked Koshihikari GBR extract using 80% methanol and sonication (GKB4) revealed the highest amounts of tricin, caffeic, ρ-hydroxybenzoic, ρ-coumaric, ferulic, salicylic, and cinnamic acids (1.71, 1.01, 0.62, 0.45, 0.94, 2.50, and 0.37 mg/g DW, respectively), consistent with the strongest antiradical activities in DPPH and ABTS assays (IC50 = 1.47 and 1.70 mg/mL, respectively). Non-cooked GBR Koshihikari extract using 80% ethanol and sonication (GKB9) exhibited the highest MA and MB contents (147.73 and 118.8 μg/g DW, respectively). Notably, GKB9 showed potent inhibition of α-amylase and α-glucosidase (IC50 = 0.48 and 0.15 mg/mL, respectively), compared with the anti-diabetic drug acarbose (IC50 = 0.26 and 2.48 mg/mL, respectively). The findings hold significant implications for developing phenolic- and momilactone-enriched brown rice with health-beneficial properties.

Published: December 2023

The NEET phenomenon in southern Europe is particularly alarming. Most studies have focused on analysing the socio-demographic characteristics of NEET and policies directed towards them, but more research is needed regarding the psychological aspects that underlie this condition. This paper, grounded in the bioecological model, aims to analyse the psychological dimensions regarding the functioning of Public Employment Services (PESs) in three countries that rely on the South Mediterranean welfare model. Between November 2022 and September 2023, research was conducted across six rural PES locations in Italy, Spain, and Portugal, based on interviews and focus groups with PES operators and young NEET users. Thematic analysis identified two central axes: Enhancing Relationships and Building Strategic Action, which were crucial for improving NEET-PES interactions and fostering connections between PES and other community entities. The results highlighted the importance of psychological elements in the effective involvement of NEETs in policy initiatives.

Published: December 2023

In the Old World, phlebotomine sand flies from the genus Phlebotomus are implicated in the transmission of Leishmania spp. parasites (Kinetoplastida: Trypanosomatidae) and viruses belonging to the genus Phlebovirus (Bunyavirales: Phenuiviridae). Two of the five sand fly species known to occur in Portugal, Phlebotomus perniciosus and Ph. ariasi, the former being the most ubiquitous, are recognized vectors of Leishmania infantum, which causes visceral leishmaniasis, the most prevalent form of leishmaniasis in the country. Phlebotomus perniciosus is also the vector of the neurotropic Toscana virus, which can cause aseptic meningitis. Entomological surveillance is essential to provide fundamental data about the presence of vectors and the pathogens they can carry. As such, and given the lack of data in Portugal, an entomological survey took place in the Algarve, the southernmost region of the country, from May to October 2018. Polymerase chain reaction assays were performed in order to detect the presence of the above-mentioned pathogens in sand fly pools. Not only were both Leishmania parasites and phleboviruses detected during this study, but more importantly, it was the first time their co-circulation was verified in the same sand fly population collected in Portugal.

Published: December 2023

The incorporation of renewable energy sources necessitates the upgrade of the electrical grid to a smart grid, which involves the implementation of smart meters. Although smart meters provide benefits to users, many smart meter implementation projects have failed to be accepted by users. This article assesses the factors influencing the acceptance of household smart meters in Joinville, a city in the south of Brazil. Based on the Unified and Extended Theory of Acceptance and Use of Technology (UTAUT2), a structural equation model was estimated using data from a sample of 136 respondents in the city of Joinville. The results indicate that Performance Expectancy, Hedonic Motivation, and Social Influence constructs have a more substantial effect on the Intention to Use smart meters. The results provide evidence for planning the upgrade of the electrical grid by implementing smart meters in southern Brazil.

The new coronavirus infection causes severe respiratory failure following respiratory tract infection with severe acute respiratory syndrome-related coronavirus (SARS-CoV-2). All currently approved vaccines are administered intramuscularly; however, intranasal administration enhances mucosal immunity, facilitating the production of a less invasive vaccine with fewer adverse events. Herein, a recombinant vaccine combining the SARS-CoV-2 spike protein receptor-binding domain (RBD), or S1 protein, with CpG-deoxyoligonucleotide (ODN) or aluminum hydroxide (alum) adjuvants was administered intranasally or subcutaneously to mice. Serum-specific IgG titers, IgA titers in the alveolar lavage fluid, and neutralizing antibody titers were analyzed. The nasal administration of RBD protein did not increase serum IgG or IgA titers in the alveolar lavage fluid. However, a significant increase in serum IgG was observed in the intranasal group administered with S1 protein with CpG-ODN and the subcutaneous group administered with S1 protein with alum. The IgA and IgG levels increased significantly in the alveolar lavage fluid only after the intranasal administration of the S1 protein with CpG-ODN. The neutralizing antibody titers in serum and bronchoalveolar lavage were significantly higher in the intranasal S1-CpG group than in every other group. Hence, the nasal administration of the S1 protein vaccine with CpG adjuvant might represent an effective vaccine candidate.
Germinated Wheat as a Potential Natural Source of Antioxidants to Improve Sperm Quality: A Canary Trial
Authors: Özkök Arda Onur , Kilinç Gözde
Published: December 2023

The present study was carried out to determine the effects of germinated wheat on some spermatological parameters (motility, abnormal spermatozoa, hypo-osmotic swelling test (HOST), and viability) in male Gloster canaries. For this purpose, the canaries were divided into two groups, each consisting of six canaries, one control (C), and the other experimental group (GW). Group C was fed commercial canary feed. The GW group was fed germinated wheat (germinated for 5 days) and commercial canary feed. The canaries were kept individually in four-storey cages (60 cm × 50 cm × 40 cm). In this study, which lasted 2 months, feed/water was provided ad libitum and lighting was applied daily for 16 h (turned on at 05:30 and turned off at 21:30). At the end of the experiment, the sperm samples obtained from the canaries were examined in terms of the aforementioned parameters. The effects of germination time × concentration, germination time, and solvent rate on DPPH radical scavenging activity and phenolic compounds in germinated wheat were significant (p < 0.001). The highest DPPH (2, 2-diphenyl-1-picryl hydrazyl) radical scavenging activity (86.06%) and phenolic content (316.25 mg GAE/g) in germinated wheats were obtained on the fifth day (90% solvent rate) of germination. It was determined that germinated wheat did not significantly affect abnormal sperm and HOST values (p > 0.05). However, it significantly affected the motility and viable sperm rates (p < 0.05). As a result, it is thought that germinated wheat can be used as a natural antioxidant source to increase motility and vitality in canary sperm.

Published: December 2023

Analysis of the essence, content and forms of the scenario state of Japan in 2040, reflected in the 11th Scientific and Technical Forecast of NISTEP in 2019, revealed a number of conceptual dialectical contradictions. They narrow down to the question of admissibility and expediency of changing a man’s nature in order to ensure his prosperous, safe, meaningful and happy existence. The author proposes for discussion a conclusion on inevitability of the transhumanization of a mankind on the scale of a single country (Japan) and the whole world, given the nature of the great challenges facing it. The possibility of keeping the historical development in a conditionally humanistic direction is noted, given the emphasis of social reforms in Japan, reflected in the 6th Basic Plan for scientific, technical and innovative development of the country, on building a society for the fullest realization and use of human intellectual potential.

Published: December 2023

Budget is an estimated forecast of future incomes and expenditure for a certain period of time. Budget is usually prepared for regular time intervals such as monthly, quarterly, or annually. Budgets are prepared by the top management of the organization. This research identifies direct materials cost as the most appropriate base for flexible budgeting, and hence it is used as the activity of interest. Differential penalty costs for budget variances specified by the user determine an optimal ratio which is used in developing the flexible budget. In many manufacturing company, plant costs such as depreciation, rent, etc has a very large proportion of total costs, and these aspects tend to be considered as fixed costs.  Salary costs also tend to be considered as fixed, because employees are generally guaranteed a basic salary for a working week of an agreed number of hours. As the appearance of growth on service industries, labour costs such as wages or fixed salaries and overheads place a major role on most of the costs of a business, and direct materials will have a relatively small value under total costs.

Published: December 2023

This paper explores the relationship between Accounting-Based Relative Performance Evaluation (RPE) and CEO compensation within the context of corporate governance. The theoretical foundations for RPE are agency theory, economic theory, and stakeholder theory, and the study explores the complexities of CEO compensation, incorporating frameworks like agency theory, tournament theory, and human capital theory. Employing a qualitative descriptive approach, the paper analyzes existing literature to unravel the applications, benefits, and challenges of RPE in CEO compensation. The results and discussion section scrutinizes the RPE process, emphasizing peer benchmarking, defining performance metrics, quantifying relative performance, adjusting for external factors, and incorporating risk and effort sharing. Accounting-Based RPE emerges as a critical subset, offering financial alignment, objective performance metrics, and a shareholder value focus. The paper acknowledges challenges, including data accuracy, comparability issues, and concerns about short-termism. Furthermore, it underscores the integral role of corporate governance in shaping the impact of RPE on CEO compensation.

As a research methodology, a literature review will be used in this study. This study discusses the clinical applications of tDCS in several diseases, such as Alzheimer's, Parkinson's disease, depression, drug and food compulsion, as well as its application in the process of physical and respiratory performance. Recent studies suggest that a new field of applicability of tDCS may be related to a probable ergogenic effect induced by it, especially on the production of muscle and respiratory strength, aerobic performance and perception of exertion.
Kształtowanie kompetencji komunikacyjnych w aspekcie psychologicznym w zarządzaniu bezpieczeństwem państwa
Authors: Majchrzak Natalia
Published: December 2023

State security management, like any organisation, requires not only the provision of appropriate forces and resources but also the proper transmission of information and messages. Only the ability to send and receive messages correctly ensures efficient implementation of assigned tasks, their understanding, and execution. For the process of managing them to proceed properly, it is essential to follow the rules of interpersonal communication. In this context, it is necessary to further define the elements of communication competence. They can be divided into five psychological and linguistic components. They are also determinants of proper communication (i.e. correct, appropriate, and at the same time effective). These include having a high level of communication awareness, presenting a high communication culture, active listening, using appropriate feedback,, and avoiding communication barriers. The results of research on the communication competences of the surveyed students allow us to draw the conclusion that their level of communication awareness is too low, which is a quite a disturbing phenomenon, because it is the awareness of mistakes made or deficiencies and ignorance in the discussed area that is an essential element of improving communication competence. The multitude of aspects for which communication competences are of great importance is almost unlimited, and therefore emphasing the need for their guided development and improvement is a priority.
Wstęp do rozważań na temat obrazu MEDIO AMBIENTE (ŚRODOWISKO) w języku hiszpańskim
Authors: Sońta Martyna
Published: December 2023

The article is a collection of reflections constituting an introduction to the reconstruction of the MEDIO AMBIENTE (ENVIRONMENT) image in Spanish. In the introduction, the author discusses the methodological basis of the research, which is the theory of the linguistic image of the world and the method of its reconstruction proposed by Jerzy Bartmiński as part of the EUROJOS seminar. She then presents an analysis of the textual material, which consists of quotations that are collocations of the word medio ambiente. The results of the analysis make it possible to indicate the defining features of MEDIO AMBIENTE which constitute the image and the way of valuing the environment in Spanish.
“It’s in the law”: An ethnographic account of the effects of the introduction of lay participation on judicial bureaucracies in Greater Buenos Aires
Authors: Amietta Santiago Abel , Barrera Leticia
Published: December 2023

The province of Buenos Aires (Argentina) introduced its first criminal jury system in 2013. This article discusses the design and initial findings of an ethnographic research project looking at this legal innovation with particular attention to the effects of the introduction of new (lay) actors – and their practices, knowledges, experiences – to the criminal justice system, bringing to the analysis rules, spaces, temporalities and people that are bound by this phenomenon. Focusing on the initial stages of the process – the draw and summoning of prospective jurors and jury selection hearings –, we discuss how material and temporal constraints to fulfill the legal mandate of incorporating lay decision-makers give place to the reshaping and (re)creation of certain roles and positions within the bureaucratic structure. We argue that the jury has become a spectral presence that alters a myriad of existing practices, characters and responsibilities in the criminal justice of Buenos Aires that goes well beyond their verdicts.
Introduction. Empirical research with judicial professionals and courts: Methods and practices
Authors: Casaleiro Paula , Roach Anleu Sharyn , Dias João Paulo
Published: December 2023

The articles in this special issue focus on the methodological and practical challenges of undertaking empirical research in judicial and/or court settings. They arose from a workshop at the International Institute for the Sociology of Law held on 23-24 June 2022 which discussed the empirical strategies to access and conduct research with judicial officers and the research methods and kinds of data used, including interviews, surveys, court observations, administrative data, documents, and photographs. The articles draw on the experiences of socio-legal researchers within the field, address the importance of linkages with the justice system and discuss a range of socio-legal insights, methodological approaches and methods from disciplines such as anthropology, law, political science, psychology and sociology.

Determinación de los receptores para estrógenos y progesterona, en tejidos placentarios fetales y maternos porcinos, y su relación con la concentración sérica y tisular
Authors:   , Viglierchio María del Carmen
Published: December 2023

Se estudió la expresión de receptores de estrógenos y de progesterona en placentas porcinas de diferentes períodos gestacionales y su relación con la concentración de estrógenos y progesterona en suero y homogenatos de placenta materna y fetal. La expresión de receptores de Estrógenos (α y β) y de Progesterona (isoformas A y B) se realizó por inmunohistoquímica y la determinación de sus ligandos mediante quimioluminiscencia. Se hallaron diferencias significativas en los valores de estrógenos (Es) a los 17 dg entre los componentes maternos y fetales placentarios y el suero. Se obtuvieron altas concentraciones de progesterona (P4) en extractos fetales a los 17 y 70 dg. A los 17 dg se observó inmunomarcación nuclear del REβ en el epitelio luminal y glandular, RPA en epitelio glandular y tejido conectivo, y REβ en células epiteliales trofoblásticas. Mientras que a los 70 dg se observó expresión de RPA en epitelio glandular y tejido conectivo, y REβ en células epiteliales trofoblásticas. Los resultados obtenidos sugieren que los Es fetales interactúan con los REβ en el epitelio trofoblástico y la P4 se liga a los RPA en el tejido conectivo endometrial para modular la expresión de moléculas de señalización y sus receptores relacionados con la implantación, el mantenimiento de la gestación y con la remodelación placentaria. Se postula que la relación temporal entre las concentraciones séricas y tisulares de Es y P4, y la expresión de sus receptores es determinante para promover la comunicación entre la hembra porcina y los conceptuses, y que el descenso de Es hallado entre los 15-20 días de preñez que se acompaña de un aumento de P4, y de una desaparición de los RPA en el epitelio luminal uterino es esencial para la implantación y la continuidad de la gestación.
GENDERED COMMUNICATION AND MANIPULATION: A COMPARATIVE ANALYSIS OF FEMALE SPEECH IN THE ADVERTISING INDUSTRY
Authors: Malyuga Elena N. , Khaperstkova Anna A.
Published: December 2023

This study aims to identify and assess the manipulative potential of language used in corporate culture through an analysis of female employees' speech in Canadian and British advertising agencies. By addressing this research gap, the study seeks to answer the question of how gender influences the use of manipulative strategies in advertising. To investigate this question, the study employs a comparative research design, complemented by a qualitative analysis of the findings. The research material includes business speeches, presentations, interviews, and articles featuring narratives produced by female respondents working in Canadian and British advertising agencies. The findings suggest that women use emotional and persuasive language to appeal to clients and create a positive attitude towards advertised products. Study results outline specific linguistic differences between Canadian and British female advertising professionals in terms of their use of manipulative language strategies.
Konut Projelerinde İdeal İş Süresinin Tahmini İçin Bir Hesaplama Yöntemi Önerisi
Authors: TIRATACI Hakan , YAMAN Hakan
Published: December 2023

İnşaat projelerinde süresel gecikmelerin yönetimi, dünya genelinde araştırmacılar arasında büyük ilgi görmektedir. Bu konudaki geniş literatür, iş süresini etkileyen çok sayıda faktör olduğunu öne sürmektedir. Bu faktörlerle iş süresini belirmeye yönelik tahmin yöntemleri, daha güvenilir araçlar ve etkin zaman performansı sağlamak açısından önceki araştırmalarda kullanılmıştır. İş süresi hesaplama tekniklerinin önemli potansiyeli olmasına rağmen, bu yöntemler sınırlı sayıdaki çalışmada ihale aşamasında ve konut projelerinde uygulanmıştır. Ayrıca Türkiye’de inşaat süresi ile ilgili araştırmalar, konut projelerinde önemli gecikmeler olduğunu göstermiştir. Bu nedenle “İdeal İş Süresi”ne ulaşmak amacıyla yeni bir hesaplama yöntemi önermek için sadece konut projelerinde inşaat süresini etkileyen faktörlerin araştırılmasına karar verilmiştir. Konut projelerine ilişkin veriler, Türkiye'de konut projeleri inşa etmede temel kurum olan Türkiye Cumhuriyeti Toplu Konut İdaresi Başkanlığı'ndan (TOKİ) elde edilmiştir. İstatistiksel veri analizinde çoklu regresyon, CHAID ve CART analizleri kullanılmıştır. Çalışmanın bulguları, her bir istatistiksel yöntem için İdeal İş Süresini önemli ölçüde etkileyen birkaç faktörün olduğunu göstermiştir. Her üç istatistiksel yöntemin de geçerliliğini test etmek için kestirim değerleri ve standart hatalar hesaplanmıştır. Regresyon formülü, önerilen hesaplama yönteminin sınanmasında istatistiksel anlamlılık göstermiştir. Yöntemin farklı konut projelerine de uygulanması, geciken proje sayısının önemli ölçüde azaldığını kanıtlamıştır.
