La comunicabilidad de lo ambiguo: una propuesta narratológica para el análisis de la ficción televisiva compleja
Authors: Loriguillo-López Antonio
Published: June 2019

El presente artículo propone una metodología de análisis de la narración ambigua en la ficción televisiva contemporánea, rasgo estilístico al alza entre propuestas comerciales. A través de la adaptación y aplicación de la comunicabilidad enunciada por David Bordwell como estrategia nar­rativa en su estudio de los modos de narración cinematográficos a una muestra de series dramáticas de origen anglosajón, se ofrece un primer tratamiento del modo narrativo de lo que desde los estudios televisivos se ha identificado como televisión compleja. Finalmente, se apunta a la cor­respondencia de este modelo con una nueva fase del modelo de narración del audiovisual postclásico.The present article proposes a methodology of analysis of the ambiguous narration in contemporary television fiction, a stylistic feature on the rise among commercial titles. Through the adaptation and applica­tion of the communicativeness formulated by David Bordwell as one of the categories of narrative strategies in his examination of the modes of narration in film to a sample of drama series produced in English-speaking regions, we offer a primary approach to the narrative mode of what has come to be known in the field of Television Studies as complex TV. Lastly, we note the correspondence between this model and a new phase of the audiovisual post-classical narration.
Prototipos interpretativos, prácticas de apropiación y luchas simbólicas. Replanteando las relaciones entre estos términos a la luz de un estudio empírico sobre la recepción del tango
Authors: Montes María de los Ángeles
Published: June 2019

Toda práctica de apropiación supone dos cosas: por una parte, se encuentra motivada por los intereses del agente social. Por la otra, supone a la interpretación como operación lógicamente anterior. Tan anterior se la concibe, que la semiótica cognitiva prescindió por completo del estudio de los usos de los signos. Sin embargo, creemos que existen razones para revisar el vínculo entre apropiación e interpretación, y la relación de esto último con los intereses de los intérpretes. Esta es la tesis que pretendemos desarrollar, que surge como resultado de un trabajo empírico sobre la recepción del tango por parte de milongueros.All appropriation practices suppose two things: on the one hand, it is motivated by the interests of the social agent. On the other, it assumes interpretation as a logical previous operation. This is so to such an extent that cognitive semiotics completely disregarded the study of the uses of signs. However, we believe that there are reasons to review the link between appropriation and interpretation, and the relationship of the latter with the interests of the interpreters. This is the thesis that we intend to develop, which arises as a result of an empirical work on the reception of tango by milongueros.
The long road from cold war to warm peace: Building shared collective memory through trust
Authors: Kappmeier Mariska , Mercy Aurélie
Published: June 2019

Conflict does not end when violence ceases. Societies faced with overcoming conflict are confronted with many obstacles in the long process of reconciliation as they move from cold war to warm peace. They have to bridge the divide of disparate collective memory while overcoming deep-rooted inter-group distrust. Disparate collective memories fuel the conflict by preserving hatred and distrust. We suggest that one step towards warm peace is the establishment of an overarching superordinate group memory, or Shared Collective Memory. Our paper introduces a theoretical reconciliation model that proposes three incremental reconciliation cycles to build a Shared Collective Memory through the parallel development of intergroup trust. It combines and expands on the existing conceptualizations of trust and of collective memory and provides a framework for future empirical research.
¿Qué actividad en la España Vacía?
Authors: Langreo Navarro Alicia , Garcia Azcarate Tomas
Published: June 2019

This note is a reflection on the empty Spain and some of the differential features of its economic activity. The analysis starts from the observation that the economic engines that assured more or less their stability in the past have failed. It focusses on the different productive systems observed in the rural areas and their capacity to carry over the rural economy as a whole, which constitutes the essential core of this contribution. The gender perspective and the emigration are incorporated into the debate. It ends with 9 proposals for possible future lines of work.
Cuando los menores declaran en la justicia de menores | When youngsters speak in juvenile justice
Authors: Bernuz Beneitez María José
Published: June 2019

Resumen: La Convención sobre los Derechos de los Niños incorpora los derechos de participación al elenco de derechos e insiste en la realización del derecho a ser escuchado porque consolidan una nueva imagen del niño como sujeto de derecho. Esa escucha del menor de edad en sede judicial, cuando ha cometido un delito, debe permitirle sentirse partícipe del proceso y que el juicio sea percibido como justo y las medidas entendidas como legítimas. Dada la trascendencia de esta escucha, es importante analizar cómo se realiza y qué sentido se le da en la declaración del menor ante la policía o la fiscalía.
Abstract: The Convention on Children's Rights incorporates the rights of participation to the list of rights and insists on the realization of the right to be heard because they consolidate a new image of the child as a subject of law. That hearing of the minor in juvenile justice, when he/she has committed a crime, should allow him/her to participate of the process and perceive the trial as fair and the measures as justified. Given the importance of this hearing, it is important to analyze how it is done and the meaning of it in the declaration of the minor before the police or the prosecutor's office.

Les males paraules: insults masculins a la València baixmedieval
Authors: López Juan Guillermo
Published: June 2019

Resum: L’insult, en l’Edat Mitjana, és més que un mitjà per a ofendre un individu. L’omnipresent cultura de l’honor, que impregna la societat i determina el comportament d’homes i dones, el converteix en oprobi, en l’avergonyiment públic de la persona injuriada. Les respostes a aquest tipus de situacions eren diverses, en funció del gènere i la posició social de l’individu i, també, del seu criteri personal, però el ventall d’opcions era ampli: replicar amb altre insult; la violència; apel·lar als testimonis de la injúria; i, finalment, recórrer als tribunals de justícia. A la València al tombant del Tres-Cents, sembla que aquest últim recurs era força freqüent, especialment entre les classes populars; i, per aquesta raó, conservem nombrosos clams i demandes que ens han permès observar com es produïa i desenvolupava la violència verbal a la ciutat. En el present article, analitzarem l’insult masculí a finals del llarg segle XIV, parant esment en els termes fets servir més freqüentment; els espais als quals es produïen la major part dels episodis; i, finalment, en la centralitat de la violència física com a resultat, resposta o acompanyant de l’ofensa verbal. 
Paraules clau: insults, honor, injúria, violència 
Abstract: Insults were, during the Middle Ages, more than a way to offend an individual. The ubiquituous culture of honour, which impregnated society and determined men’s and women’s behaviour, turned them into vituperation, into the public shaming of the insulted person. The responses to these situations were diverse, and depended on the gender, social standing and, ultimately, personal criteria of the slandered individual, but the range of options was broad: retorting with another insult; responding with violence; appealing to the witnesses of the insult; and, finally, denouncing the insulter at the courts of justice. In Valencia, by the end of the 14th century, it seemed that this last resort was particularly frequent, especially among the populace; for this reason, there have been preserved numerous court claims and prosecution records that allow us to observe how verbal violence occurred in the city. In this article, we will analyze insults against men at the end of the 14th century, focusing specially on the slanders more commonly used; the spaces in which verbal disputes took place; and, finally, on the centrality of physical violence as a result, response or companion to verbal offense.

Identification of microRNA-21 target genes associated with hair follicle development in sheep
Authors: Zhai Bo , Zhang Lichun , Wang Chunxin , Zhao Zhuo , Zhang Mingxin , Li Xu
Published: June 2019

Aim

The target molecule regulatory function of microRNA-21 (miR-21) in multiple signalling pathways has become a main focus of genetic and pharmacological regulatory studies of various diseases. The identification of target genes for miRNA-21 in the development of hair follicles can provide new research pathways for the regulation of cell development.

Methods

In the present study, eight six-month-old ewes from Super Merino (SM) and Small Tailed Han (STH) sheep breeds were selected. Target prediction and dual-luciferase wild-type and mutant vectors were used to identify the target genes of miR-21. Quantitative reverse transcription polymerase chain reaction (RT-qPCR) and bioinformatics analysis were conducted to analyze the effects of miR-21.

Results

The results show that the expressions of CNKSR2, KLF3 and TNPO1 were downregulated by miRNA-21 at rates of 36%, 26% and 48%, respectively. Moreover, there was a significant negative correlation between the expression of miR-21 and the three target genes in sheep with two extreme phenotypes. The expression of microRNA-21in October was significantly lower than that in January and February; while the expression of CNKSR2, KLF3 and TNPO1 in October was higher than that in January and February. Conclusions: These results suggest that CNKSR2, KLF3 and TNPO1 are three newly discovered target genes of miR-21 and might be involved in the effects of miR-21 on hair follicle development.
Population-, sex- and individual level divergence in life-history and activity patterns in an annual killifish

Published: June 2019

Variation in life-history strategies along a slow-fast continuum is largely governed by life-history trade-offs. The pace-of-life syndrome hypothesis (POLS) expands on this idea and suggests coevolution of these traits with personality and physiology at different levels of biological organization. However, it remains unclear to what extent covariation at different levels aligns and if also behavioral patterns such as diurnal activity changes should be incorporated. Here, we investigate variation in life-history traits as well as behavioral variation at the individual, sex and population level in the Turquoise killifish Nothobranchius furzeri. We performed a common garden laboratory experiment with four populations that differ in pond permanence and scored life-history and behavioral (co-) variation at the individual and population level for both males and females. In addition, we focused on diurnal activity change as a behavioral trait that remains understudied in ecology. Our results demonstrate sex-specific variation in adult body size and diurnal activity change among populations that originate from ponds with differences in permanence. However, there was no pond permanence-dependent divergence in maturation time, juvenile growth rate, fecundity and average activity level. With regard to behavior, individuals differed consistently in locomotor activity and diurnal activity change while, in contrast with POLS predictions, we found no indications for life-history and behavioral covariation at any level. Overall, this study illustrates that diurnal activity change differs consistently between individuals, sexes and populations although this variation does not appear to match POLS predictions.
Automatic generation of objective footprint outlines
Authors: Lallensack Jens N.
Published: June 2019

The objective definition of footprint margins poses a central problem in ichnology. The transition from the footprint to the surrounding sediment is often continuous, and the footprint wall complex, requiring interpolation, approximation, and a priori assumptions about trackmaker anatomy to arrive at feasible interpretations of footprint shapes. The degree of subjectivity of such interpretations is substantial, and outlines produced by separate researchers can differ greatly. As a consequence, statistical shape analysis, regardless if based on linear and angular measurements or on the shape as a whole, are neither fully repeatable nor objective. Here I present an algorithm implemented in the programming environment R that is able to generate continuous footprint outlines based on three-dimensional models—fully automatically, objectively, and repeatable. The approach, which is based on contour lines extracted from the model, traces the outline at the point where the slope of the track wall is steepest. An option for automatic landmark placement is implemented for tridactyl footprints. A case study was carried out on 13 footprints of a single trackway of a theropod trackmaker from the Lower Cretaceous of Münchehagen, Germany. Analysis of the landmark coordinates returned by the script did reproduce statistical results published in an earlier study that was based on human-made interpretative drawings, demonstrating the applicability of the present method for the objective and quantitative shape analysis of tracks. Although faint anatomical details are not always recorded and features not related to the foot anatomy may be included, the generated outlines tend to correspond with human-made interpretative drawings regarding the overall shape. While not suited as a full replacement of interpretative drawings, these generated outlines may be used as an objective basis for such interpretations.
Impact of Trade Liberalization on Employment in West African Economic and Monetary Union (WAEMU): A Gender Approach
Authors: Agbahoungba Lesfran Sam Wanilo
Published: June 2019

The main objective of this paper is to assess the impact of trade liberalization on employment in West African Economic and Monetary Union (WAEMU) through a gender approach. We apply generalized least squares (GLS) estimation techniques with both random and fixed effects on panel data covering the period of 2000-2017. Due to the lack of data, Guinea-Bissau is not part of our analysis. The results show that, while trade liberalization does not explain women’s employment patterns, it rather contributes in job destruction for men in the WAEMU. In conclusion, the impact of trade liberalization of employment is not gender neutral. Rather, it varies depending on the sex of people. In terms of policy implications, this study calls policy makers to setting up, better negotiating or renegotiating trade agreements and implementing trade policies that are more inclusive and beneficial particularly to the population. This could be done by taking into consideration women’s employment particularities in the union, enhancing productive capacities of men, reducing and eliminating inequalities related to people gender and sex.
Comparison of Mindfulness, Death Anxiety and Defensive Mechanisms in Addicted and Nonaddicted People
Authors: Pourmand Toba
Published: June 2019

The purpose of this study was to compare mental health, death anxiety and defense mechanisms in addicted and nonaddicted people. The research method is descriptive of comparative causal type. The statistical population of the study consisted of all addicts and nonaddicted people in Zahedan city. The sample consisted of 200 people (100 addicted men and 100 non-addicted men) who were volunteers for non-addicts who were volunteers. The tool used in this research was a questionnaire of 39 items of mind-consciousness [1], a questionnaire of 40 items of defense mechanisms [2], Templar death anxiety inventory (1970). The statistical method used in descriptive and inferential level was used to analyze the variance analysis of variables and independent t-test. The results showed that there was a significant difference in the components of mindfulness, such as action with mindfulness, lack of judgment, and observation in addicted and non addicted people, as the mean of action component with mindfulness and lack of judgment in lower addicted people From non-addicted And the average component of observation in addicts is higher than non-addict. Also, there is a meaningful difference in the concept of death anxiety in addicted and non-addicted people. The mean of death anxiety in addicted people is higher than non-addicted people. Also, the average of psychosocial defense mechanisms in addicted people is higher than non-addicts, and there is no difference in the mechanisms of growth and non-growth in addicted and non-addicted people.
Modeling Business Performance and Macroeconomic Factors to Explain Stock Market Returns in LQ45 Indonesia Stock Exchange (IDX)
Authors: Tjandrasa Benny Budiawan
Published: June 2019

The purpose of this study is to confirm the effect of business performance and macroeconomics on stock returns in the industrial sector in the Indonesia Stock Exchange LQ45 index. This study examines eight variables from business performance and macroeconomics, namely: current ratio, debt-equity ratio, total asset turnover, return on equity, inflation rate, interest rate, exchange rate, and political stability to be tested for the effect on the stock return of the industrial sector. Using Generalized Least Square techniques, it is concluded that the Industrial sector in the Indonesia Stock Exchange is strongly influenced by macroeconomic factors rather than business performance factors. This is common in capital markets which are mostly dominated by foreigners because foreign investors are very sensitive to changes in a country's macroeconomic conditions especially if it is related to political conditions. From the iteration results, there are two multivariate regression models which are statistically considered the most suitable. The originality of this study is to prove statistically that political stability is very influential on LQ45 stock returns in the industrial sector on the Indonesia Stock Exchange

Published: February 2025

Importance

Rising out-of-pocket costs of maternal health care for people with commercial insurance may affect use of health care and outcomes. There are stark racial and ethnic disparities in outcomes, but little is known about differences in spending.

Objective

To measure differences in out-of-pocket spending for maternity care by race and ethnicity.

Design, Setting, and Participants

This retrospective cross-sectional study used administrative data from Blue Cross Blue Shield of Massachusetts from January 1, 2018, through December 31, 2022, for pregnancies, deliveries, and 42-day postpartum care. Participants were continuously enrolled during pregnancy, delivery, and 42 days post partum (collectively termed maternity episode).

Exposures

The primary characteristic of interest was the birthing person’s race and ethnicity.

Main Outcomes and Measures

The primary outcome was total out-of-pocket spending during the maternity episode. Out-of-pocket spending was measured separately for the pregnancy period, prenatal services, and delivery, by type of cost sharing, and as a percentage of the median household income in the patient’s census tract (using American Community Survey data). Race and ethnicity were measured via self-report and imputation.

Results

The analytic sample included 87 253 maternity episodes among 76 826 unique birthing persons (mean [SD] age, 32.4 [4.7] years; 99.8% female) between 2018 and 2022; among maternity episodes, 8572 birthing persons (9.8%) were Asian, 3331 (3.8%) were Black, 6872 (7.9%) were Hispanic, and 68 478 (78.5%) were White. Mean out-of-pocket spending for the maternity episode was highest among Black birthing people ($2398 [$426]), followed by Hispanic ($2300 [$572]), Asian ($2202 [$603]), and White ($2036 [$1547]) birthing people (P < .001). These differences remained statistically significant after adjusting for health and demographic characteristics. The differences were largest in the prenatal period and for coinsurance payments. Black (1003 [30.1%]) and Hispanic (2302 [33.5%]) birthing people were more likely than Asian (1569 [18.3%]) and White (12 600 [18.4%]) birthing people to be enrolled in plans with high coinsurance, but not plans with high deductibles (3317 [38.7%] for Asian, 1232 [37.0%] for Black, 2350 [34.2%] for Hispanic, and 24 515 [35.8%] for White birthing people).

Conclusions and Relevance

In this study, differences in out-of-pocket maternity spending among the commercially insured were associated with differences in coinsurance rates. These costs could lead people to forgo needed health care or other basic needs that support health (eg, food or housing). Changes to health plan benefit design could improve equity in out-of-pocket maternity spending and its consequences.

Authors: Seide Abigail , Thomas Uwemedimo Omolara , Rasul Rehana , Steinway Caren , Katzow Michelle , Jan Sophia , Kim Eun Ji
Published: February 2025

Importance

Social determinants of health (SDOH) are associated with health outcomes. Thus, providing referrals for unmet social needs within clinical settings may improve the health of children.

Objective

To examine the prevalence and demographic characteristics of pediatric families with unmet social needs and their association with families accepting help from a pediatric clinical practice.

Design, Setting, and Participants

This cross-sectional study examined data from a comprehensive SDOH screening and referral program at a large academic pediatric practice in the US. Participants were caregivers of patients younger than 17 years and indicated at least 1 social need. Data were collected from April 16, 2018, through September 29, 2019, and analyzed from November 18, 2019, through December 17, 2019. The data review was finalized December 20, 2023.

Exposure

Screening for SDOH in primary care.

Main Outcome and Measures

The main outcome was interest in assistance among patient families with at least 1 social need. Factor analyses categorized social needs as basic needs, stress, challenges to economic mobility, and marginalization. χ2 Tests and multivariable Poisson regression were used to examine the associations between patient characteristics and caregiver interest in assistance.

Results

There were 758 caregivers (median [IQR] age, 34 [29-40] years; 614 mothers [81.0%]) reporting at least 1 unmet social need, such as food or utility insecurity or unemployment. The median age of children was 23 months (IQR, 4-70 months), and 163 (21.5%)were of Asian, Pacific Islander, or Native Hawaiian ; 213 (28.1%) of Black; 156 (20.6%) of Latino or Hispanic; 37 (4.9%) of White ; and 122 (16.1%) of other race and ethnicity. A total of 315 caregivers (41.6%) were not interested in assistance. Families with basic needs (adjusted prevalence ratio [PR], 5.56; 95% CI, 3.33-10.00), stress (adjusted PR, 1.75; 95% CI, 1.43-2.17), challenges to economic mobility (adjusted PR, 2.17; 95% CI, 1.67-2.86), or marginalization (adjusted PR, 1.41; 95% CI, 1.15-1.72) were more likely to be interested in assistance. Additionally, Black race (adjusted PR, 1.23; 95% CI, 1.01-1.49), other race and ethnicity (adjusted PR, 1.22; 95% CI, 1.01-1.47), and inadequate social support (adjusted PR, 1.85; 95% CI, 1.32-2.63) were associated with acceptance of referral services.

Conclusions and Relevance

These findings suggest that the implementation of referral programs may help to achieve health equity, especially among marginalized populations, and improve the referral process for families who have social needs but are not interested in assistance.
High‐resolution and high‐fidelity diffusion tensor imaging of cervical spinal cord using 3D reduced‐FOV multiplexed sensitivity encoding (3D‐rFOV‐MUSE)
Authors: Yuan Chenglang , Chen Shihui , Liang Liyuan , Xu Xiaorui , Xiong Hailin , Li Yi , Liu Tianbaige , Chen Nan‐Kuei , Chang Hing‐Chiu
Published: February 2025

Purpose

To develop a 3D isotropic high‐resolution and high‐fidelity cervical spinal cord DTI technique for addressing the current challenges existing in 2D cervical spinal cord DTI.

Methods

A 3D multi‐shot DWI acquisition and reconstruction technique was developed by combining 3D multiplexed sensitivity encoding (3D‐MUSE) with two reduced FOV techniques, termed 3D‐rFOV‐MUSE, to acquire 3D cervical spinal cord DTI data using a sagittal thin slab. A self‐referenced 2D ghost correction method and a 2D navigator‐based inter‐shot phase correction were integrated into the reconstruction framework to simultaneously eliminate Nyquist ghost and aliasing artifacts. Cardiac triggering was used during data acquisition to minimize the influence of cerebrospinal fluid pulsation. In vivo experiments were conducted on five healthy subjects at a 1.5 T MRI scanner for evaluating the feasibility of 3D cervical spinal cord DTI using 3D‐rFOV‐MUSE in terms of geometric fidelity, reconstruction performance, and SNR efficiency.

Results

A 3D‐rFOV‐MUSE can achieve high‐resolution cervical spinal cord DTI at 1.0 mm isotropic resolution. The integration of reduced FOV and multi‐shot acquisitions can improve the geometric fidelity of 3D cervical spinal cord DTI. Compared with routine 2D single‐shot diffusion‐weighed EPI (2D‐ss‐EPI), the proposed technique can mitigate through‐plane partial volume effect and enable multi‐planar data reformation for cervical spinal cord DTI, with effective reductions of distortions and improved signal‐to‐noise ratio.

Conclusion

We demonstrated the feasibility of high‐resolution and high‐fidelity 3D cervical spinal cord DTI at 1.0 mm isotropic resolution using 3D‐rFOV‐MUSE technique, which may potentially improve the quantitative assessment of cervical spinal cord DTI biomarkers.

Aus der gegenwärtigen Diskussion um den Öffentlichkeitsbegriff leiten die Autorinnen ein substantielles Forschungsdesiderat hinsichtlich der möglichen Funktion von Literatur für die gegenwärtige Öffentlichkeit ab und entwickeln eine entsprechende Programmatik für den vorliegenden Band. Deweys pragmatische Konzeption einer institutionengestützten partizipatorischen Öffentlichkeit, die stärker auf die relationale Eingebundenheit als auf die Autonomie des Individuums setzt und Öffentlichkeit als demokratisch-diskursive Lebensführung fasst, liefert eine Grundlage für eine Reflexion der Relevanz des Ästhetischen und der Literatur für demokratische Öffentlichkeiten. Mit Hartmut Rosa, der ästhetische Formen wie Bilder, Narrationen, Geschichten und Lieder als notwendigen Stoff für die ‚viszerale Basis‘ einer lebendigen Demokratie versteht, argumentiert der Text für die Relevanz einer ästhetisch vermittelten Sphäre, die Dialoge im Modus des ‚Hörens und Antwortens‘ im öffentlichen Raum ermöglicht. Umfassende Digitalisierungsprozesse mit ambivalenten Folgen führen die Notwendigkeit normativer Konzepte demokratischer Öffentlichkeit vor Augen. Unter diesen Bedingungen eines dritten Strukturwandels der Öffentlichkeit analysieren die Autorinnen die Entwicklung und die Rolle der Literatur und des Literaturbetriebs. In den anschließenden Beiträgen werden diese Fragen mit Fallstudien adressiert.
Die weißen Räume der Literatur. Mediale Infrastrukturen als „vermachtete Arena“ literarischer Öffentlichkeit
Authors: Gilbert Annette
Published: February 2025

Medien- und sozialgeschichtlich ist das Konzept der modernen Öffentlichkeit stark an das Druckmedium und die Herausbildung solcher Räume wie Salon oder Kaffeehaus gebunden. Sie bilden die Infrastruktur der Öffentlichkeit. Spätestens mit Auftreten der Massenmedien habe sich diese allerdings, so Habermas, zu einer „vermachteten Arena“ entwickelt. Die Digitalisierung habe das emanzipatorische Versprechen einer egalitären, inklusiven Öffentlichkeit nicht einlösen können. Im Anschluss an diese Diagnose richtet der Beitrag sein Augenmerk auf die institutionalisierten Räume und technischen Infrastrukturen der unmittelbaren Gegenwart, die den Zugang zur digitalen Öffentlichkeit und die (literarische) Kommunikation in dieser ermöglichen, aber auch reglementieren und konditionieren. Dabei zeigt sich, dass aufgrund der spezifischen Entstehungsgeschichte der kommunikationstechnologischen Infrastruktur in Gestalt ihrer Soft- und Hardware die mediatisierten Räume digitaler Öffentlichkeit nie jener ‚inklusive‘, ‚frei zugängliche Raum‘ ‚ebenbürtiger‘ Akteur*innen waren, als die sie imaginiert wurden. Exemplarisch ausgeführt wird dies an Werken von Fritz Balthaus, American Artist und Allison Parrish, denen ein in dieser Hinsicht hohes Erkenntnispotential eignet, da sie selbstreflexiv die medialen Räume und technischen Infrastrukturen der Öffentlichkeit, in denen sie selbst in Erscheinung treten, zum Gegenstand künstlerischer Exploration und Darstellung machen und als „vermachtete Arena“ zu erkennen geben.
„The You You Are“. TV-Serien als öffentliches Medium von Sozial- und Selbsttechnologien
Authors: Hoepker Karin
Published: February 2025

„The You You Are“ diskutiert die Rolle zeitgenössischer, US-amerikanischer Streaming-Serien als Ort gesellschaftlicher Selbstreflexion in der Tradition des Romans des neunzehnten Jahrhunderts. Als Intervention in Aushandlungsprozesse um Formationen des „unternehmerischen Selbst“ (Bröckling) nimmt der Beitrag die Workplace-Serie als ein Genre in den Blick, das Sozial- und Selbsttechnologien im Kontext von halböffentlichen Räumen in Großorganisationen einnehmen. Der Arbeitsplatz, das Büro, die Firma fungieren in Serien wie Homecoming (Amazon, 2018–2020) und Severance (Apple TV+, 2022–) als zentrales Setting an der Schnittstelle zwischen Privatem und Öffentlichem. Die Serien inszenieren soziale Mikrokosmen einer nahen Zukunft, die von fortschreitenden Ökonomisierungsdiskursen und restriktiv-disziplinarischen Praktiken der Selbstoptimierung gezeichnet sind. Wie eine genauere Lektüre von Severance exemplarisch aufzeigt, nehmen die Serien insbesondere die Organisationsform großer Korporationen in den Fokus, deren umstrittene Rolle als Stakeholder in deliberativen Prozessen um Verantwortung und Einflussnahme ein Topos öffentlicher Diskussionen seit dem frühen zwanzigsten Jahrhundert ist. Die ästhetischen Strategien der Serien machen Strukturen und historische Verbindungslinien sichtbar und unterlaufen de-historisierende, technooptimistische Fortschrittsnarrative. Indem sie etwa auf ikonische Architektur und Design der Corporate Era oder Figuren wie den „organization man“ zurückgreifen, ermöglichen sie eine kritische Kontextualisierung zeitgenössischer Selbsttechniken innerhalb der disziplinarischen Zusammenhänge komplexer Genealogien des Subjekts.

Indicator-based (multi-objective) diversity optimization aims at finding a set of near (Pareto)optimal solutions that maximizes a diversity indicator, where diversity is typically interpreted as the number of essentially different solutions. Whereas, in the first diversity-oriented evolutionary multi-objective optimization algorithm, the NOAH algorithm by Ulrich and Thiele, the Solow Polasky Diversity (SP Diversity, also known as Magnitude [1]) served as a metric, other diversity indicators could be considered. We examine the parameter-free Max-Min Diversity and the Riesz

Focusing on multi-objective diversity optimization, we discuss different diversity indicators from the perspective of indicator-based evolutionary algorithms with multiple objectives. We examine theoretical, computational, and practical properties of these indicators, such as monotonicity in species, twinning, monotonicity in distance, strict monotonicity in distance, uniformity of maximizing point sets, computational effort for a set of size

The two scales of new physics in loop-induced Higgs couplings
Authors: Nortier Florian , Rigo Gabriele , Sesma Pablo
Published: February 2025

Abstract

Probing new physics through precise measurements of Higgs boson couplings is a central objective of the particle collider program at the high-energy frontier. An anomaly in Higgs couplings induced solely by new fermions allows one to compute an upper bound on the mass scale of new bosons. This new bosonic scale is necessary to prevent Landau poles or vacuum instability. Consequently, a single anomalous measurement can provide insight into two distinct new physics scales. In this article, we apply this approach to the loop-induced couplings of the Higgs boson to digluons (gg), diphotons (γγ), and Zγ, and we compare our results to the projected sensitivities of the HL-LHC and future lepton colliders. This work naturally extends our previous analysis of Higgs couplings to weak dibosons (WW and ZZ).
Remote Hawking-Moss instanton and the Lorentzian path integral
Authors: Saito Daiki , Oshita Naritaka
Published: February 2025

Abstract

The Hawking-Moss (HM) bounce solution implies that the tunneling amplitude between vacua is uniquely determined by the vacuum energy at the initial vacuum and the top of a potential barrier, regardless of the field distance between them ∆ϕ. This implausible conclusion was carefully discussed in [E. J. Weinberg, Phys. Rev. Lett. 98, 251303, (2007)], and it was concluded that the conventional HM amplitude is not reliable for a transition to the top of distant local maxima (hereinafter referred to as the remote HM transition). We revisit this issue and study the impact of the quantum tunneling effect on the remote HM transition. We demonstrate that the amplitude for such a distant transition is indeed smaller than the conventional HM amplitude by employing the Lorentzian path integral in a simple setup. We consider a linear potential, which allows for analytic treatments, and evaluate the up-tunneling probability of a homogeneous scalar field in de Sitter spacetime. The Picard-Lefschetz theory is employed to identify the relevant Lefschetz thimble, representing the relevant tunneling trajectory. We then compare the resulting transition amplitude with the conventional HM amplitude. We find that when the field separation |∆ϕ| is larger, the quantum-tunneling amplitude, estimated by our Lorentzian path integral, is smaller than that of the conventional HM amplitude. This implies that the transition amplitude may be significantly suppressed if the thermal interpretation is not applicable and the quantum-tunneling effect is dominant for the remote HM transition.
From G2 to SO(8): Emergence and reminiscence of supersymmetry and triality
Authors: Gao Zhi-Qiang , Wu Congjun
Published: February 2025

Abstract

We construct a (1+1)-dimension continuum model of 4-component fermions incorporating the exceptional Lie group symmetry G
2. Four gapped and five gapless phases are identified via the one-loop renormalization group analysis. The gapped phases are controlled by four different stable SO(8) Gross-Neveu fixed points, among which three exhibit an emergent triality, while the rest one possesses the self-triality, i.e., invariant under the triality mapping. The gapless phases include three SO(7) critical ones, a G
2 critical one, and a Luttinger liquid. Three SO(7) critical phases correspond to different SO(7) Gross-Neveu fixed points connected by the triality relation similar to the gapped SO(8) case. The G
2 critical phase is controlled by an unstable fixed point described by a direct product of the Ising and tricritical Ising conformal field theories with the central charges c =

, respectively, while the latter one is known to possess spacetime supersymmetry. In the lattice realization with a Hubbard-type interaction, the triality is broken into the duality between two SO(7) symmetries and the supersymmetric G
2 critical phase exhibits the degeneracy between bosonic and fermionic states, which are reminiscences of the continuum model.

Published: February 2025

Purpose

This study aimed to investigate the effects of dose escalation through focal boost (FB) to intraprostatic lesions (IPLs) as well as the role of gallium-68 prostate-specific membrane antigen positron-emission tomography (68Ga-PSMA-PET/CT) for staging and treatment planning in patients with Gleason score (GS) 10 prostate cancer (PCa) receiving definitive radiotherapy (RT) and androgen deprivation therapy (ADT).

Materials and methods

We retrospectively analyzed data of 92 patients with GS 10 PCa who underwent definitive RT and ADT from March 2010 to October 2022. Freedom from biochemical failure (FFBF), prostate cancer-specific survival (PCSS), distant metastasis-free survival (DMFS), and overall survival (OS) rates were calculated using the Kaplan–Meier method. Survival outcomes were compared between patients staged with 68Ga-PSMA-PET/CT and those staged with conventional imaging modalities as well as between those who received a simultaneous integrated boost (SIB) and those who did not.

Results

At a median follow-up time of 73 months, the 5‑year FFBF, PCSS, DMFS, and OS rates were 59.2%, 77.0%, 62.9%, and 67.6%, respectively. Disease progression was observed in 39 patients (42.4%), with most cases manifesting as distant metastasis (DM). A total of 56 patients (60.9%) were staged using 68Ga-PSMA-PET/CT, while 43 patients (46.7%) received FB to IPLs. Patients staged with 68Ga-PSMA-PET/CT had better FFBF and PCSS compared to those staged with conventional imaging. Patients undergoing an SIB had improved PCSS and DMFS. In the multivariable analysis, an ADT duration of 18 months or more was associated with improved FFBF, PCSS, DMFS, and OS. Application of an SIB was an additional independent predictor for improved FFBF, while staging with 68Ga-PSMA-PET/CT was associated with better PCSS.

Conclusion

We found that long-term ADT, increasing the radiation dose to primary tumor, and staging with 68Ga-PSMA-PET/CT improved clinical outcomes. Additional research is needed for validation.
Boosting the accuracy of property valuation with ensemble learning and explainable artificial intelligence: The case of Hong Kong
Authors: Deng Lin , Zhang Xueqing
Published: February 2025

This paper proposes a novel three-level ensemble learning model to boost the accuracy of property valuation. Compared with current machine learning models, our ensemble learning strategies perform better. Explainable artificial intelligence methods are applied to identify significant housing price determinants. The results show that most features have nonlinear relationships with price. The property’s age and geographic coordinates are the most important features and the density and diversity of urban amenities positively relate to price. The number of building blocks or housing units shows a threshold effect on price, and a price premium of higher public transit accessibility is witnessed. Implications for future property development and urban planning are provided regarding building rehabilitation and renewal, property development preparation and urban center identification, land use planning and architectural design, integrated development of metropolitan amenities, and transit-oriented development.

Any pores formed during laser welding of copper hairpins affect the structural integrity and the mechanical/electrical functionality of the joint. We report on investigations using synchrotron X-ray imaging techniques to observe the formation of the pores in the processing zone while welding. It was found that all pores are formed at the joint gap and that the small pores are distributed throughout the complete joint volume as a result of the melt flow induced by the movement of the laser beam. This insight has led to the development of a welding strategy that minimizes pore formation by avoiding the movement of the laser beam across the joint gap. This was achieved by rapid beam shaping based on coherent beam combining (CBC) technology.
