Differences in the dependency on income for subjective well-being
Creators: name: Beckwith, WIlliam James Deakins
Publisher: name: Macquarie University
Year: 2023
Subjects: classificationCode: 380102
subject: Behavioural economics

description: Set point theory argues subjective well-being (SWB) varies between people, but has stability within people across time, fluctuating in response to external factors before returning to an individual’s unique mean. However, there are individual differences in how much SWB varies, suggesting some individuals may conform more closely to the set point model than others. Income appears to serve as a buffer to the impact of external factors on SWB variability, but this impact is hypothesized to differ by individual’s dependency on income for SWB. Longitudinal data from 5048 Australians were used to calculate contingent units from the participant’s annual reports of income, affective well-being, and life satisfaction. These individual estimates assessed the association between income and SWB based on an individual’s within-person data, producing unique scores for this association’s strength and direction. Individuals with stronger contingent units represent a greater dependency on external factors to determine SWB, so theoretically have a poorer fit to the model of set point theory. The contingent units demonstrated normal distribution, high reliability, and significantly moderated the relationship between within-person reports of SWB and income; suggesting this application of the contingent unit method is psychometrically sound. Contingent unit strength predicted moderate increases to SWB variability. Importantly, this effect was stronger than for other variables in the regression model: trait SWB, income, personality, and age. These results support the hypothesis that dependency on income for SWB predicts SWB variability, suggesting SWB variability acts as an effective indicator of fit to the model of set point theory.
Relocating Social Justice to the Axis of Citizenship—For a Deaf Mediation

description: Based on the tangible relationship of strangeness seen in the lines of communication between a deaf and a hearing individual, in which full comprehension of the (gestural) linguistic metaphors used among the deaf is not always assimilated, and vice versa, we will from the beginning put emphasis on the differences and ruptures between the fields of representation and communication. We will thereupon approach deafness as a relationship by deconstructing the view of disability, i.e. by granting privilege to the differences yet underscoring the equality of intelligence (the wise hearing individual versus the profane deaf). It is from this standpoint (the recognition of difference) that so-called profane knowledge gains visibility and importance in the upward climb to the expertise acquired by the deaf. Nevertheless, it is fundamental to know how to coordinate this recognition with the conquests of redistributive social justice. Finally, we explore the central role of the (deaf) mediator in the construction of meaning and citizenship, especially when dealing with the isolated deaf, with the objective of underpinning situations of marginality that, perhaps unintentionally, are shaped by the social project.

An assessment of the evidence from ATLAS3D for a variable initial mass function

description: The ATLAS3D Survey has reported evidence for a non-universal stellar initial mass function (IMF) for early type galaxies (ETGs) (Cappellari et al. 2012, 2013b,a). The IMF was constrained by comparing stellar mass measurements from kinematic data with those from spectral energy distribution (SED) fitting. Here we investigate possible effects of scatter in the reported stellar mass measurements and their potential impact on the IMF determination. We find that a trend of the IMF mismatch parameter with the kinematic mass to light ratio, comparable to the trend observed by Cappellari et al. (2012), could arise if the Gaussian errors of the kinematic mass determination are typically 30%. Without additional data, it is hard to separate between the option that the IMF has a true large intrinsic variation or the option that the errors in the determination are larger than anticipated. A correlation of the IMF with other properties would help to make this distinction, but no strong correlation has been found yet. The strongest correlation is with velocity dispersion. However, it has a large scatter and the correlation depends on sample selection and distance measurements. The correlation with velocity dispersion could be partly caused by the colour-dependent calibration of the surface brightness fluctuation distances of Tonry et al. (2001). We find that the K-band luminosity limited ATLAS3D Survey is incomplete for the highest M/L galaxies below 10^10.3 M_sun. There is a significant IMF - velocity dispersion trend for galaxies with SED masses above this limit, but no trend for galaxies with kinematic masses above this limit. We also find an IMF trend with distance, but no correlation between nearest neighbour ETGs, which excludes a large environmental dependence. Our findings do not rule out the reported IMF variations, but they suggest that further study is needed.

Education of Roma Women Between Feminism and Multiculturalism Study Case: Roma Women in Romania

Publisher: name: JSSE - Journal of Social Science Education
Year: 2012

description: In the present paper I analyze the way gender relations and women’s rights are negotiated inside the minority communities living in Romania. The paper highlights the intersection between ethnicity and gender, and the struggle between conserving the identity as well as norms and values of the traditional Roma communities. My main theoretical approach is based on Okin’s (1998, 1999) view that there is an existent tension between feminism and multiculturalism, between group rights and individual rights. I analyse the way the state’s decision to protect the identity of a community (in order to give groups the total freedom to decide their private sphere of life) may affect the rights of the individuals who are part of that community. The paper specifically investigates how access to education is negotiated between traditional Roma communities and the Romanian state, moreover, and looks closely at how such negotiations affect the Roma women in their decisions making. Concerning these issues, I analyze the situation of Roma women’s rights in the context of the intersection between patriarchal societies and Romanian society in which gender inequalities have been minimalized and women have won rights and freedoms equal with the one owned by men. Finally, I intend to draw suggestions for public policies through which individual rights a group rights should become compatible but without the harm of the first.

description: Ziel dieser Arbeit war die Analyse der fotografischen Darstellung österreichischer Politiker_innen auf den Instagram-Seiten österreichischer Zeitungen. Der Fokus dieser Arbeit lag darauf mithilfe vorangegangener Rezeptionsforschung zu analysieren wie die Politiker_innen im Gesamten dargestellt werden und ob es Unterschiede zwischen den Geschlechtern gibt. Insgesamt wurden mittels einer Vollanalyse der Instagram-Seiten 1054 Fotos durch eine quantitative Inhaltsanalyse mit qualitativen Einflüssen analysiert und mit SPSS ausgewertet. Die Ergebnisse zeigen im Gesamtbild eine neutrale Berichterstattung der Instagram-Seiten, auch im Vergleich zwischen den Geschlechtern. Es gibt aber einige Variablen, bei denen eine beeinflussende Darstellungsweise gefunden werden konnte. Diese Arbeit bestätigt die angeführte Literatur in den meisten Punkten, widerspricht aber einigen Studien aus der Genderforschung.

description: This paper presents a variable-length decision-feedback scheme that uses tail-biting convolutional codes and the tail-biting Reliability-Output Viterbi Algoritm (ROVA). Comparing with recent results in finite-blocklength information theory, simulation results for both the BSC and the AWGN channel show that the decision-feedback scheme using ROVA can surpass the random-coding lower bound on throughput for feedback codes at average blocklengths less than 100 symbols. This paper explores ROVA-based decision feedback both with decoding after every symbol and with decoding limited to a small number of increments. The performance of the reliability-based stopping rule with the ROVA is compared to retransmission decisions based on CRCs. For short blocklengths where the latency overhead of the CRC bits is severe, the ROVA-based approach delivers superior rates.

description: Sparse signal restoration is usually formulated as the minimization of a quadratic cost function $\|y-Ax\|_2^2$, where A is a dictionary and x is an unknown sparse vector. It is well-known that imposing an $\ell_0$ constraint leads to an NP-hard minimization problem. The convex relaxation approach has received considerable attention, where the $\ell_0$-norm is replaced by the $\ell_1$-norm. Among the many efficient $\ell_1$ solvers, the homotopy algorithm minimizes $\|y-Ax\|_2^2+λ\|x\|_1$ with respect to x for a continuum of $λ$'s. It is inspired by the piecewise regularity of the $\ell_1$-regularization path, also referred to as the homotopy path. In this paper, we address the minimization problem $\|y-Ax\|_2^2+λ\|x\|_0$ for a continuum of $λ$'s and propose two heuristic search algorithms for $\ell_0$-homotopy. Continuation Single Best Replacement is a forward-backward greedy strategy extending the Single Best Replacement algorithm, previously proposed for $\ell_0$-minimization at a given $λ$. The adaptive search of the $λ$-values is inspired by $\ell_1$-homotopy. $\ell_0$ Regularization Path Descent is a more complex algorithm exploiting the structural properties of the $\ell_0$-regularization path, which is piecewise constant with respect to $λ$. Both algorithms are empirically evaluated for difficult inverse problems involving ill-conditioned dictionaries. Finally, we show that they can be easily coupled with usual methods of model order selection.

description: Software is an integral part of any business, which makes the significance of high-quality software in today’s digital age undeniable. However, despite the advancements in software testing, challenges persist in efficiently planning, generating, and executing test cases, particularly for REST API-based applications. This project addresses the issue by developing a sequence generator tool that enables testers to effortlessly create and execute sequences of requests, streamlining the creation of comprehensive test scenarios. By simplifying the process of connecting response values to subsequent request values, the software seeks to maximize test coverage, improve test quality, and enable testers to focus more on software quality enhancement than the efforts of test construction. The client for this project is Testifi GmbH, a company dedicated to enhancing software delivery processes through DevOps integrations and AI-automated quality assurance solutions. The main focus of the project was to find out if the test quality increased by using the sequence generator tool due to more edge cases and more complex scenarios being tested compared to manual API testing, as well as showing if the efficiency improvement can be measured in reduced amount of time necessary for creation sequences. To answer these questions and develop an application that offers value for Testifi GmbH, a literature review was conducted on the subjects of basic user interface design and user experience concepts for advanced users. Based on the findings, the user interface of the application was outlined and the software implemented. During development and with the finished product, multiple sets of user tests were conducted with users experienced in working with APIs, to improve the design and software during development, and to gain insights about the effectiveness of the final product. Those tests showed that the main goals of the project could be reached by demonstrating a considerable amount of time saved by using the application, while also outperforming manual testing methods in efficiency and ease of use. Key features like the linking of response values to subsequent request values and the suggestion of such links based on Testifi’s Pulse Artificial intelligence (AI) as well as previously created sequences were well received by testers and customer. The literature review also proved to be very valuable as users praised the straightforward design, while never missing any important data. When Testifi GmbH integrates the end product in their pulse workflow, its ability to create sequences easily and intuitively as well as the potential of the additional link suggestions created by the tool to be used in improving the Pulse AI will be indispensable.

description: Why do some electoral systems change, and others stagnate? This question has seen many answers in literature, the two that have garnered the most focus being partisan interest and accordance with certain values. The partisan interest is that where a legislator is pursuing a
change, or not, to maximize their caucuses gains and minimize their losses. The pursuit of reform to remain in accordance with certain values is when a legislator pursues a reform, or not, to bring the electoral system in line with values that they see as central in the system and
society. These values, according to Virgin (2021), were under the umbrella of the “common good”. Some examples that Virgin pointed to were that of egalitarianism and self-reliance.

description: Does after the crisis mean before the crisis? Financial crises are part of the economic cycle and therefore not only absolutely normal but under certain circumstances beneficial. Is this also true for the ongoing financial crisis? It might be too soon to draw final conclusions, but financial crises show a great potential to encourage learning from the past and to foster socio-economic education. That’s not meant as a belittlement of the financial crisis, but should sharpen the mind to notice a primary dilemma of our economic system: Even though increasing credit facilities contributed to the economic prosperity during the last decades, the development of savings and debts should be in balance with the long-term productive capacity of society, economy and environment. The authors will review certain aspects and causes of the financial crisis under social und environmental constraints and will discuss possible long-term paths of development from an economic perspective. Following this, didactical implications will be considered and feasible learning content will be discussed.

With specific forms of the diffusion, drift and sink coefficients, the eigenfunctions can be expressed in terms of hypergeometric functions. We obtain the relevant discrete and continuous spectra for the eigenfunctions. With non-zero sink terms the discrete spectra eigenfunctions are generalisations of well known orthogonal polynomials: the so-called associated-Laguerre, Bessel, Fisher-Snedecor and Romanovski functions. We use a MacRobert's proof to obtain closed form expressions for the continuous normalisation of the Romanovski density function. Finally, we apply our results to obtain the analytical solutions associated with the Bertalanffy-Richards Langevin equation.

description: Economic crisis, during the past two years, has an impact on Greek students of 17 years old. Elements of the crisis have intruded on their everyday life. Economic and financial concepts constitute part of their attempt to understand the world they live in and as a result affect their educational level. This paper is an exploratory attempt to study the effects of economic crisis in the economics knowledge of Greek students using a sample of 62 Senior High School (lyceum) students. Data analyzed consists of a 30 question exam based on the Test of Economic Literacy (TEL) developed by the National Council on Economic Education (NCEE) and a questionnaire which was given at the end of the exam. The survey was conducted in two different periods in 2010-2011 & 2011-2012. Results indicate that students level of knowledge of economic and financial concepts, concerning the crisis, is considerably high compared with quantitative results from the U.S. national norming sample of the TEL.

description: The penetration of wireless broadband services in remote areas has primarily been limited due to the lack of economic incentives that service providers encounter in sparsely populated areas. Besides, wireless backhaul links like satellite and microwave are either expensive or require strict line of sight communication making them unattractive. TV white space channels with their desirable radio propagation characteristics can provide an excellent alternative for engineering backhaul networks in areas that lack abundant infrastructure. Specifically, TV white space channels can provide "free wireless backhaul pipes" to transport aggregated traffic from broadband sources to fiber access points. In this paper, we investigate the feasibility of multi-hop wireless backhaul in the available white space channels by using noncontiguous Orthogonal Frequency Division Multiple Access (NC-OFDMA) transmissions between fixed backhaul towers. Specifically, we consider joint power control, scheduling and routing strategies to maximize the minimum rate across broadband towers in the network. Depending on the population density and traffic demands of the location under consideration, we discuss the suitable choice of cell size for the backhaul network. Using the example of available TV white space channels in Wichita, Kansas (a small city located in central USA), we provide illustrative numerical examples for designing such wireless backhaul network.

description: Internal combustion engines will continue to play a role during a transitional phase, especially in heavy-duty or marine applications. In this context, lean-burn gas/dual-fuel combustion is an attractive concept to reduce CO2, combined with considerably lower particulate and NOX pollution, and with efficiencies comparable to diesel combustion. However, ignition processes still pose considerable challenges, with pre-ignition in particular being a major issue. The underlying mechanisms are probably based on self-ignition of lube oil in hot zones. In order to investigate fundamentals of such phenomena in optically accessible test rigs, a novel injector was specifically developed to induce pre-ignitions artificially. The so-called “PieZo-Droplet-Injector” (PZDI) enables dosing of minor amounts of lubricating oil or even the injection of single droplets with diameters in the range of 100–200 µm. The working principle relies on a needle actuated with a piezo stack, which pushes a certain amount of lube oil in a bore so that (even single) droplets can be ejected through an adjustable nozzle. To confirm the PZDI functionality and to investigate droplet characteristics based on adjustable operating parameters, tests were performed under ambient conditions as well as in a constant volume combustion chamber under reasonable pressure and temperature conditions. Overall, the PZDI showed an excellent behavior in terms of capabilities to inject small amounts or even single droplets of lube oil. At last, this specially developed injector allows selective lube oil addition in an optically accessible engine test facility for upcoming examination of pre-ignition phenomena under real operating conditions.

description: Due to stringent emission regulations, it is of practical significance to understand cycle-to-cycle variations in the combustion of fossil or renewable fuels to reach future emission regulations. The present study aims to conduct a parametric investigation to analyse the influence of the valve lift and different mass flows of an inlet valve of the test engine “Flex-OeCoS” on the flow structures. To gain a deeper understanding of the flow behaviour, an optical test bench for 2D Particle Image Velocimetry (PIV) and a Large Eddy Simulation (LES) are used. Turbulence phenomena are investigated using Proper Orthogonal Decomposition (POD) with a quadruple decomposition and the Reynolds stress transport equation. The results show good agreement between the PIV and LES. Moreover, the main flow structures are primarily affected by valve lift while being unaffected by mass flow variation. The turbulent kinetic energy within the flow field increases quadratically to the mass flow and to the decreasing valve lift, where large high-energetic flow structures are observed in the vicinity of the jet and small low-energetic structures are homogeneously distributed within the flow field. Furthermore, the convective flux, the turbulent diffusive flux, the rate of change, and the production of specific Reynolds stress are the dominant terms within the specific Reynolds stress transport equation.

Rheumatoid arthritis specific variants

description: Rheumatoid arthritis (RA) is a multifactorial autoimmune disease that causes chronic inflammation of the joints, with an aetiology still unclear. RA is a complex inflammatory disease that involves an interconnected array of genetic, environmental, and epigenetic factors. Recently, systems biology and network-based approaches have been proposed to study such complex diseases. Combining multiple data types allows us to discover new knowledge as integration can help compensate for missing or unreliable information. Moreover, if multiple sources of evidence point to the same outcome then it is less likely to obtain false positives. Among computational approaches, machine learning stands out as a promising field in bioinformatics, as it allows for integration of multi-omic biomedical datasets. In this work, we present our efforts to integrate different layers of biological data in the form of networks in order to obtain a global view of the disease. To do so, we make use of publicly available transcriptomic datasets (peripheral blood) relative to RA and a variety of bioinformatics analyses such as statistical analysis, differential expression analysis, and machine learning network inference (Nicolle et al., 2015) to infer an RA-specific TF co-regulatory network. The TF cooperativity network is subsequently enriched in signalling cascades and upstream regulators using the state of the art RA map based on the functional overlaps between the two networks (Singh et al., 2020). Lastly, a list of RA specific variants available in DisGeNET (Piñero et al., 2020) will be used as an overlap to highlight key genes associated with known disease mutations. We combine three different biological layers (gene expression, signalling cascades, mutations), obtained by bottom-up prior knowledge-based (DisGenNET, RA map) and top-down data-driven (CoRegNet) methods to build an integrative, disease-specific network. The goal behind this endeavor is to unravel mechanisms governing the regulation of key genes identified as mutation carriers in RA and also derive patient-specific models to gain more insights into the disease heterogeneity.

description: Understanding cycle-to-cycle variations (CCV) is of practical importance for the combustion of fossil and renewable fuels, as increasingly stringent emission regulations require reductions in the negative effects of such variations. The subject of this study is the flow around inlet valves, since oscillations of such inlet flows affect the flow structure in the cylinder and are thus one of the causes of CCV. To this end, a parametric analysis of the influences of the mass flow rate and valve lift of two parallel engine intake valves on the flow structures is performed. This follows on from an earlier similar study where the flow around a single intake valve was investigated. To analyse the flow behaviour and, in particular, the interactions of the flow leaving these two valves, an optical test rig for 2D particle image velocimetry (PIV) and a large eddy simulation (LES) are used. Proper orthogonal decomposition (POD), together with a quadruple decomposition and the Reynolds stress transport equations, are used to study the turbulence phenomena. The PIV and LES results are in good agreement with each other. The detailed LES analysis of the flow structures shows that, for small valve lifts, the flow separates along the whole perimeter of the intake valve, and for larger valve lifts, the flow escapes only to one side. This is, for combustion engines with the tumble concept, the stage at which the tumble movement develops. Moreover, the flow structures are strongly influenced by the valve lift, while they are unaffected by the variation in the mass flow. The turbulent kinetic energy in the flow field increases quadratically with a decreasing valve lift and increasing mass flow. The large, high-energetic flow structures are particularly dominant near the jet, and the small, low-energetic structures are homogeneously distributed within the flow field. The specific Reynolds stress transport equation shows the limitations of two-dimensionality and large timesteps in the PIV results and the limitations of the LES model.

description: In einer Gesellschaft, die von einer zunehmenden Migrationsbewegung geprägt ist, gibt es immer mehr Schüler*innen, die das bildungssprachliche Niveau, das im österreichischen Schulsystem gefordert wird, nicht erreichen. Trotz speziellen Förderkursen und -klassen für jene mit Deutsch als Zweitsprache, gelingt es den Jugendlichen oftmals nicht die Hochsprachlichkeit zu erlangen, die für einen erfolgreichen Bildungsweg notwendig ist. Aus diesem Grund wurde in der vorliegenden Arbeit ein Modell für den sprachbildenden Lateinunterricht entwickelt, der es den Schüler*innen ermöglichen soll, in literarische Texte einzutauchen, den Wortschatz zu erweitern und die deutsche Grammatik zu wiederholen und zu vertiefen. Dabei gilt es folgende Fragen zu beantworten: I. Wie kann Latein als Sprachbildung für Lernende einer heterogenen Gruppe unter Berücksichtigung der jeweiligen Erstsprache in der Mittelschule umgesetzt werden? a. Welche Schwierigkeiten können auftreten? b. Welche positiven Effekte kann dieses Modell auf die Schüler*innen haben? Um die Forschungsfragen beantworten zu können, wurde das entwickelte Modell an einer niederösterreichischen Mittelschule getestet und empirisch beforscht. Dafür wurden über vier Monate hinweg Daten in Form von offenen Fragebögen für die Lateinschüler*innen gesammelt und ergänzend wurden explorative Expert*inneninterviews mit deren Deutschlehrer* innen durchgeführt, um eine komplementäre Quelle für Schwierigkeiten, aber ebenso für positiven Effekte eines solchen Modelles zu haben.

Material and Methods. A total of 87 subjects were assigned to a heterophoric prism group (N=32), a heterophoric control group (N= 31) or an orthophoric control group (N= 24) according to their MCH heterophoria. In the heterophoric prism group, the subjects were prescribed glasses with a prismatic correction for 6 months according to their distance correction; in contrast, the subjects in the heterophoric control group had to wear glasses without prismatic correction for the same period. The effect of the prisms on complaints due to asthenopic symptoms was investigated by comparing the total sum obtained in the CISS questionnaire at the beginning of the study and after 6 months (before and after wearing glasses) for the 3 groups. Results. A (long-term) prism effect was not apparent in the CISS total score. In both the heterophoric prism group and in the heterophoric control group, the CISS total score increased slightly and non-significantly after 6 months. When considering the heterophoric subjects with an increased CISS score at baseline, a nevertheless slight but non-significant decrease of symptoms was observed. All changes were observed in both the heterophoric prism group and the heterophoric control group. An additional analysis using binocular profiles showed a reduction in symptoms by numbers and specifically for subjects with reduced vergence facility. Conclusion. Wearing an individual, horizontal prismatic correction had no effect on the overall CISS-score for our test subjects. Further methods that allow a systematic recording of symptoms and optometric parameters are probably necessary to observe an effect. These could be binocular profiles that classify individuals according to their binocular parameters.

description: Drawing on work conducted on the use of the analysis of social representations in a school context and on the management of relationships with knowledge about socially acute economic issues, a medium-term survey (2000 to 2009) was conducted in several European countries of students who were at the end of the cycle in their economics programmes at lycée, or secondary school. The study examined the students’ system of knowledge representations of “economic uncertainty and risk”. The aim was to identify scientific, academic and social elements of a possible representation in this domain. The analysis will focus on a comparison between Italian and French students; it will seek to identify constants and changes, to speculate on their causes and effects, and to suggest instructional strategies that may have an impact on potential obstacles and supports for academic and civic learning.

description: Financial education has become a more popular part of general education in schools. Different social and economic backgrounds as well as experiences influence the students’ conceptualization of the same financial phenomenon. Therefore, phenomenography is an appropriate research strategy for investigating students’ deeper understanding of financial core concepts. Our research concentrates on ‘credit’ as a central phenomenon. Thirteen focus groups made up of secondary school students and university students in Germany discussed varying examples of taking out a loan. Systematizing students’ conceptualizations, the outcome space consists of four main categories: attitudes, needs, credit terms and calculation. On a deeper level we found further subcategories. The results of our explorative study can guide a chronology of teaching different concepts as well as further research.

description: The current financial-economic crisis has actualized important issues regarding the dynamics of the economic system, the relations between economy and politics, and the notions of good society. Thus the question of how economic education in school can support students’ understanding of the crisis is relevant to pose. This article asks what are the strengths and weaknesses, and also the promises and challenges, in the Finnish upper secondary school economic education, concerning teaching about the crisis? The article analyses the core curriculum for upper secondary school economic education in Finland, the available upper secondary school economy textbooks, and a selection of students’ social studies exam papers in the matriculation examination in spring 2010. The focus of the analysis is on how the current financial-economic crisis is presented in the textbooks and in the exam papers, what the competences are that the core curriculum delineates economic education should develope in students, and what capacity Finnish social studies teachers have for teaching about economy. The article proposes that the presence of historical perspectives and political analyses in economic education are important, in particular when teaching about topics like the current financial-economic crises.

description: Fateev's sausage sigma models in two and three dimensions are known to be integrable. We study their stability under RG flow in the target space by using results from the mathematics of Ricci flow. We show that the three dimensional sausage is unstable, whereas the two dimensional sausage appears to be stable at least at leading order as it approaches the sphere. We speculate that the stability results obtained are linked to the classification of ancient solutions to Ricci flow (i.e., sigma models which are nonperturbative in the IR) in two and three dimensions. We also describe a class of perturbations of the three dimensional sausage (with the same continuous symmetries) which remarkably decouple. This indicates that there could be a new solution to RG flow which is described at least perturbatively as a deformation of the sausage.

title: Der Einfluss rigider Familienstruktur auf den Zusammenhang des subjektiven sozialen Rangs mit der Neigung zu Scham
Creators: name: Tonne, Maximilian
Year: 2022

description: Theoretischer Hintergrund. Die Neigung zu Scham wird mit vielfältigen negativen Auswirkungen in Bezug auf die psychische Gesundheit und soziale Beziehungen in Verbindung gebracht. Aus evolutionspsychologischer Perspektive könnte das Schamgefühl ein Mechanismus zum Schutz der sozialen Stellung und der Verhinderung von Abwertung durch andere sein. Autoritäre Einstellungen der Eltern werden mit einer erhöhten Neigung zu Scham bei Kindern und Jugendlichen assoziiert. Rigide Familienstrukturen als Aspekt autoritärer Erziehungsstile könnten auf Grund ihrer oftmals starren Rollenstruktur und hoher Standards einen möglichen Zusammenhang zwischen subjektiven sozialen Rang und der Neigung zu Scham verstärken. Ziele. Für die Erhebung des subjektiven sozialen Rangs wurde zunächst eine eigenständige Übersetzung der Social Comparison Scale (SCS) ins Deutsche erstellt und anschließend auf ihre faktorielle Validität hin überprüft. Ziel war es außerdem Zusammenhänge und Interaktion des subjektiven sozialen Rangs und der Rigidität der Familienstruktur mit der Neigung zu Scham zu untersuchen. Methode. Es wurde eine Online-Fragebogenstudie an Jugendlichen zwischen 14 und 18 Jahren durchgeführt. Erhoben wurden die Neigung zu Scham (TESE-KJ), der subjektive soziale Rang (SCS) und die Rigidität der Familienstruktur (FACES-IV). Zur Überprüfung der faktoriellen Validität der SCS wurde eine konfirmatorische Faktorenanalyse (KFI) durchgeführt. Der Einfluss rigider Familienstruktur auf den Zusammenhang von subjektivem sozialem Rang mit der Neigung zu Scham wurde mittels Moderationsanalyse überprüft. Ergebnisse. Die theoretisch vorgesehene faktorielle Struktur der SCS konnte anhand der deutschsprachigen Übersetzung bestätigt werden. Es zeigte sich ein deutlicher, negativer Zusammenhang zwischen dem subjektiven sozialen Rang und der Neigung zu Scham. Rigidität der Familienstruktur hatte einen geringen, jedoch signifikanten Einfluss auf die Neigung zu Scham. Eine Interaktion des subjektiven sozialen Rangs mit der Rigidität auf das Ausmaß der Neigung zu Scham konnte nicht beobachtet werden. Zusammenfassung. Die Bedeutung des sozialen Vergleichs für das Empfinden von Schamgefühl kann vor dem Hintergrund der Untersuchung bestätigt werden. Es konnte zudem eine valide und reliable Übersetzung der SCS erstellt werden.

description: We consider pairs of Lie algebras $g$ and $\bar{g}$, defined over a common vector space, where the Lie brackets of $g$ and $\bar{g}$ are related via a post-Lie algebra structure. The latter can be extended to the Lie enveloping algebra $U(g)$. This permits us to define another associative product on $U(g)$, which gives rise to a Hopf algebra isomorphism between $U(\bar{g})$ and a new Hopf algebra assembled from $U(g)$ with the new product. For the free post-Lie algebra these constructions provide a refined understanding of a fundamental Hopf algebra appearing in the theory of numerical integration methods for differential equations on manifolds. In the pre-Lie setting, the algebraic point of view developed here also provides a concise way to develop Butcher's order theory for Runge--Kutta methods.
