Gendered Divergence in the Impact of Parenthood on Wages: The Role of Family Size, Human Capital and Working Time
Authors: Bari Lauren 
Published: July 2023

AbstractWhile gender pay disparity is a frequently researched area, few have focused on how parenthood and family size impact the wages of mothers and fathers together. The purpose of this study is therefore to take a broader view of this pivotal topic, one which has continued relevance as governments and organisations seek to advance gender equality. The findings show clear gendered divergence in the impact of parenthood on wages, with ‘motherhood wage penalties’ and ‘fatherhood wage premiums’ in both annual and hourly wage. The widest gap in earnings between women and men occurs at three or more children even when human capital and labour market selectivity factors are controlled for. For women, the largest penalty occurs at one and three or more children while for men, having two children represents the peak point in terms of wage gains to parenthood. Accounting for working time through hourly wage estimations narrows but does not eliminate parental wage gaps, pointing to other factors such as occupational segregation.
LGBTQ Victim-Survivors' Experiences and Negotiations of Service Worker and Service System Discrimination
Authors: Lim Gene , Lusby Stephanie , Carman Marina , Bourne Adam 
Published: July 2023

Abstract

Purpose
This study examined the experiences of LGBTQ victim-survivors who sought out support from domestic violence services in Australia. While the literature on intimate partner violence (IPV) is increasingly focused on improving LGBTQ inclusivity and cultural safety within both service and policy contexts, the experiences of LGBTQ victim-survivors themselves are often absent from these discussions. Consequently, little is understood about how LGBTQ victim-survivors navigate and negotiate service contexts that are frequently optimized for cisgender, heterosexual victim-survivors.

Methods
Structured life history interviews were conducted with (N = 29) LGBTQ victim-survivors aged 19–79 years of age who had recent (< 2 years) or ongoing experiences of IPV.

Results
LGBTQ victim-survivors' help-seeking behaviors are undertaken against the backdrop of a highly variegated service landscape. Individual service organizations and service workers' attitudes towards LGBTQ clients can run the gamut from inclusive and culturally sensitive to heterosexist and exclusionary, with little outward distinction between such. While participants within our study demonstrated the ability to deftly navigate or minimize the incidence of such treatment, there were clear limits to the extent that deploying such strategies would successfully enable victim-survivors to access service support. The additional psychological costs of cautiously navigating service systems were also not insubstantial and contributed significantly to both service disengagement and poorer service outcomes.

Conclusions
Efforts to expand service capabilities to improve service uptake and service outcomes for LGBTQ victim-survivors must be attentive to, and address the impact of anticipated and experienced discrimination on service provision.
Characteristic curves for Set-Valued Hamilton-Jacobi Equations
Authors: Visetti D. 
Published: July 2023

AbstractThe method of characteristics is extended to set-valued Hamilton-Jacobi equations. This problem arises from a calculus of variations’ problem with a multicriteria Lagrangian function: through an embedding into a set-valued framework, a set-valued Hamilton-Jacobi equation is derived, where the Hamiltonian function is the Fenchel conjugate of the Lagrangian function. In this paper a method of characteristics is described and some results are given for the Fenchel conjugate.

Abstract

Wadi Abu Subeira area contains many farms and houses and is one of the promising areas for iron mining. Therefore, 21 surface soil samples were collected and investigated for toxic heavy metals (Pb, Cr, Ni, Cu, Zn, Co, and As) using inductively coupled plasma (ICP) to establish a geochemical baseline for these metals during pre-mining conditions. To decipher the sources of these metals and their interrelationships, multivariate statistical analysis was applied, while to evaluate the degree of pollution and potential environmental risks the environmental indices were used. Abundances of Pb, Cr, Ni, Cu, Zn, Co, and As fluctuated from 17.72 to 0.06, 47.12 to 10.86, 47.88 to 9.25, 45.04 to 6.23, 51.93 to 17.82, 10.55 to 1.24, and 7.04 to 1.66 mg/kg, respectively, displaying a declining trend of Zn > Cr > Ni > Cu > As > Co > Pb. Additionally, the mean concentrations of all studied metals were found to be significantly lower than the selected international reference standards. Pearson correlation coefficient, principal component analysis, and cluster analysis revealed two geogenic geochemical associations for the studied toxic elements: (1) Zn-As-Ni-Cr-Cu-Co; and (2) Pb. Negative Igeo values were observed for all metals, which showed that the samples were uncontaminated and can be considered a geochemical baseline for the study area. Moreover, all CF values were lower than or close to 1, suggesting low contamination levels from all studied metals and supporting the association with natural geological processes. Similarly, Er and RI values of all metals were below 40 and 150, respectively, indicating a low-risk environment. Ultimately, the obtained levels of the studied metals can be used as a geochemical baseline for tracking the future changes in their accumulations in soil sediments considering the current assessment of the area as an environmentally safe area.
Sissy Hypno: Conceptualisation of Autogynephilic Persuasive Pornography (AGPP) and an Investigative Exploration of the Experiences of its Consumers
Authors: Vadapalli Sundara Kashyap , Kuss Daria J. 
Published: July 2023

AbstractAutogynephilic Persuasive Pornography (AGPP) is a type of pornography that is characterised by its unique autogynephilic and persuasive traits. Autogynephilia refers to the sexual pleasure one derives by imagining themselves as women. Known in the subculture as Sissy Hypno, this type of pornography is an altered mishmash of conventional licensed studio/mainstream pornography found on the internet, designed to interact with/persuade the user (by text or audio) and aid in the process of erotic self-feminisation. AGPP is consumed by a wide range of individuals and for a wide variety of reasons. Yet, there is little to no empirical research aimed at describing this novel form of media, the motivations of its consumers and the effects of its consumption. Therefore, this research study qualitatively explores the experiences of 16 participants (N = 16, age > 19), who consumed AGPP at the time of the study, by phenomenologically interpreting self-reported behaviour and self-described inclinations regarding AGPP use. The participants were recruited from Reddit, and the participant sample is an ethnically diverse sample consisting of men and transwomen. The key findings were categorised into the following superordinate themes: (1) Influence of AGPP on personality and individual lifestyle (2) Exploring femininity and submissive sexual behaviour and (3) Influence of AGPP on gender and sexuality. The analysis of these themes (and their subordinate themes) allows for the conceptualisation of AGPP and an analysis of its reported effects, contributes to the limited evidence of cisgender men strongly relating to Autogynephilia or erotic self-feminisation, alongside Autogynephilia being a frequent motivation for consuming AGPP. Some of the positive and negative effects of consuming AGPP (primarily focusing on gender identity, sexual attitudes and sexuality) were also identified through self-report, thereby, necessitating the need for widening the scientific exploration of Autogynephilia amongst AGPP consumers (not limited to gender categories) and the clinical implications of consuming AGPP (e.g., compulsive AGPP consumption).
Market competition, efficiency and economic liberty
Authors: Grillo Michele 
Published: July 2023

AbstractThis paper investigates efficiency and freedom as joint foundations of market economies. Whereas ideal perfect competition accommodates Mill’s principle of individual liberty in the economic arena, in real world, imperfectly competitive, markets economic freedom and efficiency appear often as conflicting values. Building on J. S. Mill’s utilitarian defense of free trade inOn LibertyChapter V, this paper puts forward a consequentialist defense of economic freedom under imperfect competition. Defense rests on the instrumental value of equal freedom, enjoyed by every market agent, as a source ofgeneralwelfare in a world of dispersed information amonguniquehuman beings. The paper has a clear impact on contemporary antitrust debate, supporting neo-Brandesians’ rehabilitation of Structuralism in antitrust also on well founded, economic,i.e.efficiency, reasons.

Published: July 2023

AbstractThe 3 most common inherited arrhythmia syndromes—Brugada syndrome, congenital long QT syndrome and catecholaminergic polymorphic ventricular tachycardia—were initially described in the previous century. Since then, research has evolved, which has enabled us to identify patients prior to the onset of potentially life-threatening symptoms. However, there are significant gaps in knowledge that complicate clinical management of these patients today. With this review paper, we aim to highlight the most important knowledge gaps in clinical research of these inherited arrhythmia syndromes.
Does shape matter? A comparative study of the usage of calibrated sieves in the study of burned human bone from archeological and forensic contexts
Authors: Budziszewski Adam 
Published: July 2023

Abstract
In recent years, the use of a set of sieves became a crucial part of the methodology in studies of burned human bone from archeological and forensic contexts. A set of three sieves (10 mm, 5 mm, 2 mm) is widely used in studies of burned human remains, particularly those from the British Isles, in order to determine bone fragmentation, following methodology proposed by Jacqueline McKinley (1993). Usually, mesh opening sizes are reported in methods; however, their shape is rarely mentioned. This study aims to analyze the potential impact of the sieve mesh opening shape on the results achieved. It was tested by sieving the human burned bones from ten cremation burials from two Polish archeological sites by using two sets of sieves (10 mm, 5 mm, 2 mm). The first had round openings, while these of the second were square. Furthermore, the intra-observer and inter-observer errors were computed to assess the significance of differences between the tested sets of sieves. The analysis of values obtained by using a distinct set of sieves revealed noticeable differences. Specifically, when comparing the results of sieving through square versus round mesh openings, the paired t-test yielded lower p-values than intra-observer error measurement. This finding suggests that the observed differentiation between two sets of sieves is less likely to be a result of random chance. However, it is important to note that the inter-observer error also showed statistically significant differences. This indicates that the sieving techniques may vary between observers, potentially impacting the results obtained. The diagonal of square mesh openings is proposed as the most probable factor causing differentiation. However, it should also be considered that the differences in the distribution of mesh openings and total sieving surfaces between square and round openings might also alter the results. In addition, the sieving surface has higher values for sieves with square mesh openings, which follows the pattern of a higher diagonal of mesh openings for square sieves. In conclusion, the shape of the mesh openings and their distribution on the surface of the sieves might have a significant impact on the results concerning burned bone fragmentation. Consequently, information about the shape of mesh openings should be included in the “Materials and methods” section, along with the specifications of the apparatus and the dimensions, as well as the diameter of the mesh openings.

AbstractThe deep-sea mining industry is currently at a point where large-sale, commercial polymetallic nodule exploitation is becoming a more realistic scenario. At the same time, certain aspects such as the spatiotemporal scale of impacts, sediment plume dispersion and the disturbance-related biological responses remain highly uncertain. In this paper, findings from a small-scale seabed disturbance experiment in the German contract area (Clarion-Clipperton Zone, CCZ) are described, with a focus on the soft-sediment ecosystem component. Despite the limited spatial scale of the induced disturbance on the seafloor, this experiment allowed us to evaluate how short-term (< 1 month) soft-sediment changes can be assessed based on sediment characteristics (grain size, nutrients and pigments) and metazoan meiofaunal communities (morphological and metabarcoding analyses). Furthermore, we show how benthic measurements can be combined with numerical modelling of sediment transport to enhance our understanding of meiofaunal responses to increased sedimentation levels. The lessons learned within this study highlight the major issues of current deep-sea mining-related ecological research such as deficient baseline knowledge, unrepresentative impact intensity of mining simulations and challenges associated with sampling trade-offs (e.g., replication).
Petrological and Geochemical Characterization of Miocene Tipam Sandstone in Parts of Cachar Fold Belt, Northeast India
Authors: Baruah Meghali , Pandey N. 
Published: July 2023

Abstract
Miocene Tipam Sandstone Formation in parts of Cachar Fold Belt, Northeast India has been studied using petrographic and geochemical attributes to investigate the composition, paleoweathering, tectonic setting, and source rock characteristics. It comprises of coarse to medium grained false-bedded multistoried ferruginous sandstone and variegated sandy clay. Petrographically, these sandstones belong to sub-lithic and lithic arenite varieties possessing an average recalculated modal composition of Q67F13R20. Geochemically, Tipam sandstones have high SiO2, more Na2O than K2O, and relatively low Fe2O3, MgO, MnO content in accordance with the modal composition. Weathering indices like CIA, CIW, PIA and ICV suggest derivation of sediments from low to moderately weathered source terrain bearing plagioclase feldspar in the range of An10 – An55 comparable to granodiorite and granite composition. Dominantly a passive margin setup with high degree of sediment recycling has been envisaged during the deposition of Tipam Sandstone Formation.
Petro-geochemical Signatures as Evidences for Tectonic Setting, Palaeoweathering and Provenance of Eocene Kopili Sandstones, Meghalaya, Northeast India

Published: July 2023

Abstract
Spectacularly preserved yet least studied middle to late Eocene Kopili Formation in parts of East Jaintia Hills district, Meghalaya has been documented to understand the provenance, tectonic setting and palaeoweathering employing petrological and geochemical attributes. The Kopili Formation is characterized by alternations of fossiliferous marl-splintery grey to black shale-siltstone and fine to medium grained ferruginous sandstone with occasional coal streaks. Petrographically, Kopili sandstone has been grouped into two categories i.e. subarkose and sublitharenite. Geochemically, Kopili sandstone possesses high SiO2 and relatively low Al2O3 and Fe2O3 confirming to the modal composition Q72.70 F6.57 RF7.01 CT3.12 Mx2.28 M2.07 HM1.82. These are quartz-rich (SiO2 75.96%) clean sandstone depicting strong negative correlation of SiO2 with rest of the major oxide except for CaO which is relatively weak. High SiO2 is in conformity with quartz enrichment (73.50%), does indicate a passive (atlantic type) continental margin set up for the deposition of Kopili Formation. Neo-development of quartz and feldspar in parts reflect high degree of diagenesis. Chemical indices like CIA, CIW, PIA and ICV reveal intense weathering under semi-arid to semi-humid climatic conditions. Besides minor contributions from continent interior, sediments were largely derived from recycled orogen involving rhyolitic / granitic sources containing plagioclase feldspars in the range of An0-An70 as evident from geochemical attributes.

exact penalty E-function method. Namely, we use the aforesaid exact penalty function method to solve a completely new class of nonconvex (not necessarily) differentiable mathematical programming problems, that is, E-differentiable minimization problems. Then, we analyze the most important from a practical point of view property of all exact penalty function methods, that is, exactness of the penalization. Thus, under appropriate E-convexity hypotheses, we prove the equivalence between the original E-differentiable extremum problem and its corresponding penalized optimization problem created in the introduced $$l_{1}$$

Semi-analytical approach to the determination of fracture permeability

Published: July 2023

AbstractProppant is one of the major elements of a hydraulic fracture process that can influence the productivity of an oil or gas well. The permeability of a propped fracture may be determined through laboratory measurements, utilizing experimental relationships, or using analytical methods. All methods have their advantages and disadvantages, and this study attempts to offers a solution that combines the various methods to achieve a practical solution. The standard measurement method for fracture conductivity and permeability is a time-consuming and delicate procedure and can be performed only at the cost of a significant degree of uncertainty. Investigating a method that can predict fracture permeability in significantly less time and with an acceptable level of accuracy would be useful for the industry. Proppant can be viewed as an unconsolidated, heterogeneous (in size distribution) although well-sorted granular packing, and the different relationships that can predict the permeability of such systems may be utilized. Such interdependencies account for the frictional pressure drop caused by the proppant particles and often neglect the pressure drop caused by the surface of the apparatus. To extend the applicability of the various models, the combination of a theoretical model that accounts for the pressure drop caused by the fracture wall with those models would have clear practical advantages. For this reason, a new equation had to be developed that establishes the relationship between the fracture permeability and the so-called modified particle friction factor. Since the frictional pressure drop correlations usually contain porosity as a parameter, determining its value under reservoir conditions is essential and a new procedure had to be developed. Since the different relationships were developed under different conditions to those under which the proppant-packs are usually used, providing a solution to the issues of their wide range of application is the primary objective of this study.

Published: July 2023

AbstractThis work created, characterized, and used a magnetic biochar catalyst that is both eco-friendly and very effective. Sugarcane bagasse was selected as primary raw material for catalyst preparation, because it is renewable and ecofriendly biomass. Catalyst created by doping sugarcane bagasse biochar with magnetic material in the form of (FeSO4·7H2O). Thermogravimetric Analysis (TGA) and Fourier Transform Infrared spectroscopy (FTIR) were used to characterize the catalyst. In addition, physical and textural characteristics of the catalyst were identified and interpreted. The characterization outcome showed that the catalyst has good catalytic qualities. For the manufacturing of biodiesel, discarded cooking oil served as the primary feedstock. The experiment was created utilizing the Box–Behnken Design (BBD) technique. There are four variables with the following three levels each: temperature, methanol to oil ratio, catalyst concentration, and reaction time. 29 experiments in total were carried out. Using the RSM function, optimization was done. The optimal conditions for obtaining biodiesel yield—temperature, methanol to oil ratio, reaction time, and catalyst weight—were 43.597 °C, 9.975 mol/L, 49.945 min, and 1.758 wt%. A study of the produced biodiesel using a FTIR showed that the conventional biodiesel IR spectra were confirmed. All physiochemical characteristics found suggested the biodiesel complied with ASTM and EN norms. Overall, the synthesized catalyst had conducted simultaneous reactions in a single batch reactor and had demonstrated suitability for converting used cooking oil to biodiesel.
