Contribution of Social Media in Shaping Self-Perceptions: A Case of Black Women
Authors: Nkuna Matimu Tsundzukani
Published: May 2024

Purpose: This study aimed to explore how social media representations of Black women’s hair shapes their sense of identity, self-concept and hair care practices.
Methodology: A qualitative cross-sectional approach was employed, with a sample size of five Black women in South Africa between the ages of 20 to 29 years old. Semi-structured interviews were conducted online with research participants that were purposively selected from social media platforms Twitter and Instagram. The use of these platforms to select participants also offered convenience to the researcher as these participants were readily available because they are already active in social media. Thematic analysis was used in data analysis while the Social Identity Theory (SIT) was utilised as the theoretical framework to interpret the findings.
Findings: Four themes were used to cluster the findings, namely self-categorization, social identification, perceived positive social identity and self-esteem restoration. The findings highlighted the role of social media in perpetuating the stereotypes which is traced to the slavery; and then highlight how the social media is used to reverse the systematic oppression of the Black women based on their hair. They also revealed that positive representations of Black hair on social media creates an attitude of self-acceptance and empowerment among Black women. Similarly, social media provides a space for Black women to connect, discuss their hair and share hair care tips, fostering a sense of belonging within the community. However, this study identified a gap in representation, as there tends to be an overrepresentation of one specific hair texture, leaving some Black women with limited or no representation, mainly those wearing dreadlocks.
Unique Contribution to the theory, practice, and policy: The research makes a unique contribution by highlighting the importance of diverse representation in South African advertisements and social media marketing for hair products, as Black women’s hair textures and journeys are not a monolith. The findings concomitantly highlight the role of social media celebrities and/or social media influencers in the social media regarding the matter under investigation from the perspective of South African women. The study also noted the need for awareness and education about the cultural and historical significance of Black hair to reduce cultural appropriation. The findings further highlight the human rights element regarding the discrimination faced by Black women due to their hair texture, this knowledge may contribute to creating inclusivity in both society and social media spaces.
Robust design methods and technologies for millimeter-wave components
Authors:   , Santiago Arriazu David
Published: May 2024

In this thesis, a novel gap waveguide topology is presented alongside an innovative manufacturing approach, complemented by a variety of design methods and topologies for gap waveguide low-pass filters (LPFs) and bandpass filters (BPFs). Moreover, a new design method for filtering antennas is proposed. The primary objective behind all these designs is to develop topologies that can effectively withstand manufacturing tolerances. To begin with, a novel gap waveguide topology is introduced and compared with existing designs from the literature, offering a promising alternative for future applications. Moreover, a cutting-edge manufacturing technique is proposed, leveraging selective laser melting (SLM) and subsequent computer numerical control (CNC) milling to address common challenges associated with selective laser melting, including surface roughness and manufacturing imperfections. In the field of microwave filters, a gap waveguide low-pass filter is presented for the first time. This approach simplifies the design process, employing closed-form expressions and rapidly performing calculations using simulation software. Additionally, several bandpass filters utilizing higher-order modes are introduced, featuring diverse topologies, including inline and stacked configurations. Notably, the innovation in their design extends to create bandpass filters with reduced sensitivity to manufacturing tolerances. This development is particularly pertinent for Q/V/W-band satellite payloads, where it significantly enhances fabrication yields compared to traditional filter designs. Lastly, this Thesis presents an innovative and comprehensive design methodology, encompassing the integration of microwave filters and antennas, known as a filtering antenna. The concept of a filtering antenna offers a multifaceted solution to address the evolving demands of modern communication systems. It combines the functionality of microwave filters with antennas, essential for signal transmission and reception. This integration not only simplifies the system architecture but also brings forth a range of benefits in terms of performance, space utilization, and overall system efficiency.
As Contribuições Patrístico-Agostinianas para a Hodierna Crise Ambiental

Published: May 2024

Esta pesquisa é constituída por duas partes distintas e relacionadas. A primeira busca demonstrar que o problema ecológico é uma realidade hodierna tendo emergido na segunda metade do século passado. Na área dos estudos teológicos, não poderia ser diferente, a Ecoteologia é um enfoque recente. Inclusive, a entrada da teologia no debate ecológico tem também uma dimensão apologética: para alguns ambientalistas, a atual crise ecológica tem suas raízes na tradição judaico-cristã. A segunda parte aborda as contribuições Patrístico-agostinianas para os debates em torno da hodierna crise ambiental. A pesquisa é bibliográfica utilizando-se de fontes primárias e secundárias. Diante da impossibilidade de encontrar nos escritos dos Padres da Igreja tratados amplos e específicos sobre a Ecoteologia. Todavia, é possível, sim, encontrar na patrística princípios filosóficos, éticos e teológicos que regularizam a relação entre homem e natureza, os quais não são apenas conciliáveis com os atuais modelos de desenvolvimento sustentável, mas os fundamentam e confirmam. Visto que uma abordagem completa do pensamento ecológico dos Padres é impossível, este trabalho de pesquisa se deterá em alguns pontos da doutrina de Ireneu, Basílio e, principalmente, Agostinho.

Published: May 2024

Аннотация: В статье поднимается проблема well being в трудовой деятельности. В работе приведены примеры опыта зарубежных авторов по внедрению well-being программ в свою кадровую политику, которые являются собирательным элементом всех кадровых программ, используемых в организации, с подтверждением их эффективности. Внедрение в организациях подобных программ дает возможность улучшения благосостояния юристов при осуществлении ими профессиональной деятельности. По сути, благодаря благополучию на работе становится возможным пересмотреть логику и экономические соображения в свете гигиены труда. Призма благополучия на рабочем месте служит для гуманизации труда и учета при организации труда не только технических и экономических факторов, но и человеческих , которыми часто пренебрегают. Установление связи между экономикой, организацией труда и здравоохранением позволяет наладить междисциплинарный диалог. Авторами статьи сделаны выводы о непосредственном влиянии данной кадровой технологии на повышение производительности труда юристов, что благоприятно влияет на их профессиональные компетенции.

Abstract: The article raises the problem of well being in work. The paper provides examples of the experience of foreign authors on the implementation of well-being programs in their personnel policy, which are a collective element of all personnel programs used in the organization, with confirmation of their effectiveness. The introduction of such programs in organizations makes it possible to improve the welfare of lawyers in their professional activities. In fact, thanks to well-being at work, it becomes possible to revise logic and economic considerations in the light of occupational health. The prism of well-being in the workplace serves to humanize work and take into account not only technical and economic factors, but also human factors, which are often neglected, in the organization of work. The establishment of a link between the economy, labor organization and health care allows for an interdisciplinary dialogue. The authors of the article draw conclusions about the direct impact of this personnel technology on increasing the productivity of lawyers, which favorably affects their professional competencies.

Famous protagonists interfere with discourse topicality during pronoun resolution
Authors: Schumacher Petra B. , Patterson Clare , Repp Magdalena
Published: May 2024

The aim of the current study is to assess the impact of the wider discourse on pronoun interpretation. We specifically look at German demonstrative pronouns (dieser) in comparison to personal pronouns (er), investigating whether dieser-demonstratives are influenced only by factors in the preceding sentence (specifically, sentence topicality) or whether they are additionally influenced by cues from the wider discourse (i.e., discourse topicality). We found that discourse topicality competes with sentence topicality for prominence, when the two cues are not aligned to one and the same referent. This had an impact on referential interpretation of both personal and demonstrative pronouns, with weakened interpretive biases when sentence and discourse topic did not converge on the same referent (Exp. 3). Our data further indicate that the introduction of a protagonist from a well-known novel blocked the emergence of the discourse topic as a prominence-lending cue for personal pronouns (Exp. 1–2). We propose that reference to the famous protagonist triggers a protagonist layer, which introduces its own set of questions under discussion, which in turn invalidates the discourse topic. Crucially, the demonstrative pronoun dieser does not consider the protagonist layer and only relies on the discourse layer for interpretation.
Kontinuierlicher Ansatz zur integrierten Grob- und Feinplanung

Published: May 2024

Flexibilität und Selbstoptimierung werden zunehmend zu Schlüsselfaktoren für eine wirtschaftliche Fertigung. Vor diesem Hintergrund hat sich die Integration der Teilauf-gaben von Arbeitsplanung und -steuerung sowie die Nutzung intelligenter Auswer-tungs- und Optimierungsroutinen als besonders wirksam erwiesen. Im Rahmen der vorliegenden Arbeit werden diese Teilkomponenten zu einem kontinuierlich und be-triebsbegleitend ausführbaren Gesamtkonzept zur ganzheitlich optimierten und inte-grierten Grob- und Feinplanung zusammengeführt. Hierfür wird eine vereinfachte Ar-beitsontologie zur Grobplanung vorgestellt, ein genetischer Algorithmus mit Wissens-basis und Methoden zur Plandatenaktualisierung sowie Stördauermodellierung entwi-ckelt. Die Ergebnisse umfassender Experimentreihen und prototypsicher Umsetzun-gen zeigen die Funktionalität des entwickelten Konzeptes sowie dessen Potenziale und Grenzen hinsichtlich der praktischen Anwendbarkeit auf.
Prozessoptimale Lagerung von Leistungsultraschallschwingsystemen
Authors: Bruns Peter
Published: May 2024

Obwohl die Rückwirkungen von Leistungsultraschallprozessen auf das Schwingsystem bekannt sind, fehlen in der Literatur Analysen zum entsprechenden Einfluss auf Lagerung und Schwingungsisolation. Diese Lücke schließt die vorliegende Arbeit. Es werden verschiedene Leistungs-ultraschallschwinger und Lagerungen modelliert, ihre Wechselwirkungen identifiziert und bewertet. Die Untersuchung berücksichtigt den unbe-lasteten Fall und idealisierte Lastkategorien aus konkreten Anwendungs-beispielen. Es werden Lagerung und Prozesslast in die Auslegung von Leistungsultraschallschwingern integriert und so eine Methode zur Identifi-kation prozessoptimaler Lagerungen entwickelt. Die experimentelle Validierung bestätigt eine Reduktion der Prozesskräfte um bis zu 40% sowie eine gesteigerte Effizienz. While the repercussions of power ultrasonic processes on the vibrational system are known, literature lacks analyses regarding their corresponding influence on mounting and vibration isolation. The study at hand addresses this gap. Various power ultrasonic oscillators and mountings are modeled, their interactions identified and evaluated. The investigation considers both, unloaded scenarios and idealized load categories from specific applications. Mounting and process load are integrated into the design of power ultrasonic oscillators, leading to the development of a method for identifying process-optimal mountings. Experimental validation confirms a reduction in process forces by up to 40% and improved efficiency.
Experimentelle und theoretische Untersuchungen zur Kondensation binärer zeotroper Gemische
Authors: Zimmermann Conrad
Published: May 2024

Die vorliegende Dissertation behandelt die Wärmeübertragung bei der Kondensation binärer zeotroper Gemische. Die Bestimmung von Wärmeübergangskoeffizienten ist wesentlicher Bestandteil bei der Auslegung und Effizienzsteigerung von Kondensatoren. Dabei liegen in der Literatur unterschiedliche Modellansätze zur Berechnung der Gemischkondensation vor, die in dieser Arbeit umfangreich untersucht werden. Daraus wird ein neuartiger sogenannter Superpositionsansatz entwickelt, der eine beschleunigte Vorausberechnung ermöglicht. Zur Validierung dieses Ansatzes werden in einer Versuchsanlage Messungen an den binären Gemischen Ethanol/Octamethyltrisiloxan (MDM), Ethanol/Hexamethyldisiloxan (MM) und MM/MDM sowie den beteiligten Reinstoffen durchgeführt. Die Daten werden genutzt, um die dominierenden Gemischeffekte zu identifizieren und daraus Kennzahlen in den generalisierten Superpositionsansatz zu implementieren.
Netzstützendes Verhalten verteilter Erzeuger im Niederspannungsnetz
Authors: Dietz René
Published: May 2024

In dieser Arbeit wird ein Konzept für die Regelung netzparalleler Stromrichter vorgestellt. Ausgangspunkt für die Betrachtungen ist der Betrieb einer Solaranlage, die dreiphasig ans Netz angeschlossen wird und die zwischenkreisseitig mit einer Batteriepufferung ausgestattet ist. Diese Annahme beschränkt einige Aspekte dieser Arbeit jedoch nicht, so dass die vorgestellten Konzepte problemlos auch für andere Anlagentypen erweitert werden können. Nennenswert sind vor allem leistungselektronische Lasten, deren Anforderungen hinsichtlich eines netzdienlichen Verhaltens durch aktuelle Normen steigen. Der innovative Kern liegt in einer Erweiterung der Leistungsregelung, welche speziell die Besonderheiten eines Niederspannungsnetzes berücksichtigen kann. Die konventionelle Leistungsregelung, welche auf der Anwendung von Statiken beruht, wird hierzu durch ein Konzept ersetzt, welches sich an die am Netzanschlusspunkt vorherrschende Netzsituation adaptiert. Bei exakter Schätzung der Netzparameter ist somit eine vollständige Entkopplung der Regelgrößen möglich, was zu einem optimierten Einschwingverhalten führt. Das Regelmodell besitzt damit eine weiterreichendere Relevanz als die klassischen Statikregelungen. Das Modell der erweiterten Leistungsregelung nutzt als Eingangsparameter unter anderem die aktuell an den Umrichterklemmen sichtbare Netzimpedanz. Obwohl die Regelung robust gegenüber Abweichungen der Impedanzparameter ist, bietet eine exakte, rückwirkungsfreie Bestimmung wünschenswerte Eigenschaften. Zur Bestimmung der Netzimpedanz wird ein quasi-passives Verfahren in die Regelung eingebunden, welches eine Messung der Impedanz über die Variation von Wirk- und Blindleistung ermöglicht. Dieses Verfahren wird hinsichtlich der typischen, im Niederspannungsnetz anzutreffenden Charakteristiken optimiert. Im Vordergrund stehen hier der Ohm’sch-induktive Charakter eines Niederspannungsnetzes, die nach den Normen zulässigen Harmonischen und die Filterung der Grundwelle über eine optimierte Phasenregelschleife. Da die Bestimmung der Netzimpedanz über das genannte Verfahren eine vergleichsweise geringe Dynamik besitzt (im Bereich einiger Netzperioden), wird unterstützend eine Impedanzschätzung über einen Partikel-Filter vorgestellt, über den ein dynamischerer Betrieb möglich ist.

Monseñor Romero, un enviado de Dios para salvar a su pueblo
Authors: Ellacuría Ignacio
Published: May 2024

En la revista de teología Sal Terrae de diciembre-1980 (año de martirio de Monseñor Romero), el P. Ellacuría se pregunta por qué Monseñor pasó, en sólo tres años, del anonimato y de la inoperancia a la universalidad pública y al máximo de eficacia social.
Ignacio Ellacuría -que, sin duda, vivió su vocación de justicia inspirado por Monseñor Romero y acaba de morir también martirialmente en la misma lucha- responde: porque, al ser asesinado el P. Grande, se rompieron los velos que le ocultaban la verdad, se llenó con la voz de la sangre del primer justo que moría martirialmente en El Salvador actual y con las voces históricas del sufrimiento del pueblo. Porque comprendió más y más que el anuncio y la realización del reino pasan ineludiblemente por el anuncio de la buena nueva a los pobres y de la liberación a los oprimidos. Porque, en consecuencia, el pueblo oprimido lo amó cálidamente, y recibió de él fuerza nueva para esperar, para luchar y ofrendar la vida; aunque los opresores lo odiaron hasta llegar a asesinarlo.

Practitioner-reported Needs for Enacting, Implementing, and Adopting OpenSciEd Curriculum Materials
Authors: McElhaney Kevin , Urban Rochelle , Kamdar Danae , Baker Anthony , Tsai KellyAnn , Roschelle Jeremy
Published: May 2024

OpenSciEd curriculum materials and professional learning resources are Creative Commons licensed, freely available, and aligned with the Next Generation Science Standards (NGSS). This report offers direction to researchers, practitioners, policymakers, and developers by identifying OpenSciEd practitioners’ most urgent needs, the factors driving these needs, promising approaches for addressing these needs, and implications for OpenSciEd-enabled research. We gathered survey responses from 155 teachers and leaders and conducted focus group interviews with 28 of the survey respondents. Our analysis indicated three broad challenge areas related to district adoption and implementation, classroom enactment and engagement, and obtaining evidence of NGSS-based student outcomes. We also identified seven themes related to supporting OpenSciEd practitioners through research, development, and innovation: (1) access to and benefits of professional learning, (2) supporting teacher agency, collaboration, and management, (3) improving teacher capacity to enact OpenSciEd, (4) meeting students’ needs, (5) shifting classroom culture, (6) enabling formative assessment practices, and (7) access to assessment resources. Notably, professional learning and other supports for teachers appear to address root causes of many challenges experienced by practitioners. More generally, we see a need for research that would elaborate how adoption and implementation of OpenSciEd could drive system-level change in science education.

Abstract. Accurately quantifying air–sea heat and gas exchange is crucial for comprehending thermoregulation processes and modeling ocean dynamics; these models incorporate bulk formulae for air–sea exchange derived in unstable atmospheric conditions. Therefore, their applicability in stable atmospheric conditions, such as desert-enclosed basins in the Gulf of Eilat/Aqaba (coral refugium), Red Sea, and Persian Gulf, is unclear. We present 2-year eddy covariance results from the Gulf of Eilat, a natural laboratory for studying air–sea interactions in stable atmospheric conditions, which are directly related to ocean dynamics. The measured mean evaporation, 3.22 m yr−1, approximately double that previously estimated by bulk formulae, exceeds the heat flux provided by radiation. Notably, in arid environments, the wind speed seasonal trend drives maximum evaporation in summer, with a minimum winter rate. The higher evaporation rate appears when elevated wind, particularly in the afternoon, coincides with an increase in vapor pressure difference. The inability of the bulk formulae approach to capture the seasonal (opposite from our measurements) and annual trend of evaporation is linked to errors in quantifying the atmospheric boundary layer stability parameter. Most of the year, there is a net cooling effect of surface water (−79 W m−2), primarily through evaporation. The substantial heat deficit is compensated by the advection of heat via northbound currents from the Red Sea, which we indirectly quantify from energy balance considerations. Cold and dry synoptic-scale winds induce extreme heat loss through air–sea fluxes and are correlated with the destabilization of the water column during winter and initiation of vertical water-column mixing.
Initial atmospheric conditions control transport of volcanic volatiles, forcing and impacts

Abstract. Volcanic eruptions impact the climate and environment. The volcanic forcing is determined by eruption source parameters, including the mass and composition of volcanic volatiles, eruption season, eruption latitude, and injection altitude. Moreover, initial atmospheric conditions of the climate system play an important role in shaping the volcanic forcing and response. However, our understanding of the combination of these factors, the distinctions between tropical and extratropical volcanic eruptions, and the co-injection of sulfur and halogens remains limited. Here, we perform ensemble simulations of volcanic eruptions at 15 and 64° N in January, injecting 17 Mt of SO2 together with HCl and HBr at 24 km altitude. Our findings reveal that initial atmospheric conditions control the transport of volcanic volatiles from the first month and modulate the subsequent latitudinal distribution of sulfate aerosols and halogens. This results in different volcanic forcing, surface temperature and ozone responses over the globe and Northern Hemisphere extratropics (NHET) among the model ensemble members with different initial atmospheric conditions. NH extratropical eruptions exhibit a larger NHET mean volcanic forcing, surface cooling and ozone depletion compared with tropical eruptions. However, tropical eruptions lead to more prolonged impacts compared with NH extratropical eruptions, both globally and in the NHET. The sensitivity of volcanic forcing to varying eruption source parameters and model dependency is discussed, emphasizing the need for future multi-model studies to consider the influence of initial conditions and eruption source parameters on volcanic forcing and subsequent impacts.
Drivers of late Holocene ice core chemistry in Dronning Maud Land: the context for the ISOL-ICE project

Abstract. Within the framework of the Isotopic Constraints on Past Ozone Layer in Polar Ice (ISOL-ICE) project, we present initial ice core results from the new ISOL-ICE ice core covering the last millennium from high-elevation Dronning Maud Land (DML) and discuss the implications for interpreting the stable isotopic composition of nitrogen in ice core nitrate (δ15N(NO3-)) as a surface ultra-violet radiation (UV) and total column ozone (TCO) proxy. In the quest to derive TCO using δ15N(NO3-), an understanding of past snow accumulation changes, as well as aerosol source regions and present-day drivers of their variability, is required. We therefore report here the ice core age–depth model, the snow accumulation and ice chemistry records, and correlation analysis of these records with climate variables over the observational era (1979–2016). The ISOL-ICE ice core covers the last 1349 years from 668 to 2017 CE ± 3 years, extending previous ice core records from the region by 2 decades towards the present and shows excellent reproducibility with those records. The extended ISOL-ICE record of last 2 decades showed a continuation of the methane sulfonate (MSA−) increase from ∼ 1800 to present while there were less frequent large deposition events of sea salts relative to the last millennium. While our chemical data do not allow us to distinguish the ultimate (sea ice or the open ocean) source of sea salt aerosols in DML winter aerosol, our correlation analysis clearly suggests that it is mainly the variability in atmospheric transport and not the sea ice extent that explains the interannual variability in sea salt concentrations in DML. Correlation of the snow accumulation record with climate variables over the observational era showed that precipitation at ISOL-ICE is predominately derived from the South Atlantic with onshore winds delivering marine air masses to the site. The snow accumulation rate was stable over the last millennium with no notable trends over the last 2 decades relative to the last millennium. Interannual variability in the accumulation record, ranging between 2 and 20 cm a−1 (w.e.), would influence the ice core δ15N(NO3-) record. The mean snow accumulation rate of 6.5±2.4 cm a−1 (w.e.) falls within the range suitable for reconstructing surface mass balance from ice core δ15N(NO3-), highlighting that the ISOL-ICE ice core δ15N(NO3-) can be used to reconstruct either the surface mass balance or surface UV if the ice core δ15N(NO3-) is corrected for the snow accumulation influence, thereby leaving the UV imprint in the δ15N(NO3-) ice core record to quantify natural ozone variability.

Abstract. Totten Glacier in East Antarctica holds a sea level potential of 3.85 m and is mostly grounded below sea level. It has the third highest annual ice discharge, 71.4±2.6 Gt yr-1, among East Antarctic outlet glaciers and has been losing mass over recent decades. Recent thinning of the Totten ice shelf is likely to be due to high basal melt rates driven by increasing intrusion of warm Circumpolar Deep Water. Here we simulate the evolution of the Totten Glacier subregion using a Full-Stokes model with different basal sliding parameterizations (linear Weertman, nonlinear Weertman, and regularised Coulomb) as well as sub-shelf melt rates to quantify their effect on the projections. The modelled grounding line retreat and decline in ice volume above floatation using the linear Weertman and the regularised Coulomb sliding parameterizations are very close, and both larger than that using the nonlinear Weertman sliding parameterization. The simulated grounding line retreat occurs only with maximal basal melt rate higher than 40 m yr-1, and is mainly on the eastern and southern grounding zone of Totten Glacier. The change of sub-shelf cavity thickness is not sensitive to the choice of basal sliding parameterization, only to sub-shelf melt rates, yielding strong volume above floatation dependence on melting through the mechanism of reduced buttressing.
