Ein Konzept für gute Entscheidungsprozesse
Authors: Habermann Frank , Schmidt Karen
Published: December 2022

Entscheidungsprozesse sind ein „Klassiker“ des Managements. Umso erstaunlicher, dass es dabei so häufig hakt. Noch erstaunlicher sind die Gründe dafür. Denn Umfragen zeigen, dass Entscheidungsprozesse meist nicht an ihrer schwer lösbaren Sachaufgabe, d. h. einem komplexen Entscheidungsgegenstand, scheitern. Vielmehr scheitern sie an einem unklaren oder gar widersprüchlichen Verständnis zwischen den handelnden Akteuren. Wer hat den Entscheidungsbedarf, wer soll, kann und will entscheiden, und wer muss in einem konkreten Entscheidungsprozess wie beteiligt werden? Dieser Artikel beschreibt ein Konzept, das hilft, diese wichtigen Fragen zu beantworten: präzise, transparent und für alle Beteiligten motivierend. Lesen Sie, wie Teams und Führungskräfte gemeinsam gut entscheiden, Klarheit über ihre Ziele erlangen und Partizipation zweckmäßig organisieren.

Review of the 23rd International Colloquium Tribology – 25-27 January 2022
Authors: Dörr Nicole , Pauschitz Andreas
Published: December 2022

The 23rd International Colloquium Tribology in January 2022 was held for the first time as an online conference only, with about 300 participants. The organising team, speakers and participants therefore made the best of this traditional event in Germany in view of the Covid-19 pandemic, even though the “online conference is not a substitute for a conference on site”, as one participant stated aptly. In almost 140 talks, 8 of which were plenary talks, new findings were reported on the topics of lubricants and additives, measuring techniques, digitalisation, coatings and surfaces, transport and industry, and sustainability. Several presentations were dedicated to the EU project “i-Tribomat”, which will soon be launched as “The European Tribology Centre” that offers services for the tribological characterisation of materials and lubricants.
Éducation familiale et soutien à la parentalité: politiques publiques, dispositifs et pratiques à l’île de La Réunion
Authors:   Université de La Réunion, Malbert Thierry
Published: December 2022

La question des rapports entretenus par les différents acteurs de l’éducation, dont les enseignants avec les parents des enfants qu’ils ont en charge, demeure une question complexe qui n’évite pas les controverses entre les positionnements parfois bien arrêtés des uns et des autres, en particulier lorsque se profile la problématique du lien. Dans le contexte de la société réunionnaise, qu’en est-il de la prise en compte de la dimension culturelle des rôles et fonctions des parents dans le cadre des pratiques éducatives professionnelles? Qu’en est-il des difficultés de la relation parents-professionnels de l’éducation dans la mise en oeuvre d’une véritable démarche co-éducative? Afin d’ouvrir quelques pistes de réflexions épistémologiques en lien avec ces questionnements, cet article présente plusieurs synthèses de nos résultats de recherche menés sur des dispositifs de soutien à la parentalité mise en place à La Réunion. Il s’agira de mieux comprendre l’approche interculturelle entre les instances éducatives telles que la famille et l’école, au regard des politiques publiques dans le contexte socio-historique des besoins de la population de l’île de La Réunion.

Published: December 2022

De forma recorrente, a educação aparece como meio privilegiado ao serviço de uma sociedade mais justa e preocupada com o bem comum. Como tal, o foco na desigual partilha de bens, causa da existência de formas de vida comunitárias distintas, obriga a descobrirmos o racional que enforma a manutenção e, em alguns casos, a intensificação destes fenómenos promotores e provocadores da desigualdade social. Pelo facto, este trabalho de natureza reflexiva tem como propósito abordar a problemática da educação nas regiões e nas escolas de periferia a partir dos conceitos de equidade e justiça na educação, o que só é possível fazendo uma incursão pelas políticas educativas que expressam a hegemonia da racionalidade instrumental, fazendo do mercado o seu princípio orientador. Certos de que estas políticas não conseguem anular, por vezes até fortalecem, as desigualdades sociais, tentamos conhecer as variáveis que justificam os resultados que as escolas de contextos considerados periféricos apresentam quando comparadas com outras de contextos considerados centrais.

Authors: Li Yanliang , Liu Lanhua , Li Zhiqiang
Published: December 2022

In order to promote the application of noise map in high-speed railway noise management, the high-speed railway noise map drawing technology based on the combination of noise prediction model and geographic information system (GIS) is studied. Firstly, according to the distribution characteristics of noise sources and line structure characteristics of high-speed railway, the prediction model of multi equivalent sound sources and the calculation method of sound barrier insertion loss of high-speed railway are optimized; secondly, a three-dimensional geographic information model of a high-speed railway is built in GIS software, and the railway noise prediction technology based on the model is developed again; then, the noise of discrete nodes is calculated, and the continuous noise distribution map is drawn by spatial interpolation. The research results show that the comparison error between the noise map of a high-speed railway drawn by this technology and the measured results is less than 1 dB (A), which verifies the accuracy and practicality of the high-speed railway noise map, and can be used as a reference for the railway noise management department to formulate noise control countermeasures.
Dendroclimatic analysis and cartographic modeling of the climatic response of Fagus sylvatica during growth in a sector of the central Cantabrian Mountains
Authors: Lallana-Llorente Víctor
Published: December 2022

The wide distribution of the common beech (Fagus sylvatica) in Europe reveals its great adaptation to diverse conditions of temperature and humidity. This interesting aspect explains the context of the main objective of this work: to carry out a dendroclimatic analysis of the species Fagus sylvatica in the Polaciones valley (Cantabria), an area of transition with environmental conditions from a characteristic Atlantic type to more Mediterranean, at the southern limit of its growth. The methodology developed is based on the analysis of 25 local chronologies of growth rings sampled at different altitudes along the valley, generating a reference chronology for the study area. Subsequently, the patterns of growth and response to climatic variations are estimated through the response and correlation function, and the most significant monthly variables in the annual growth of the species are obtained. Finally, these are introduced into a Geographic Information System (GIS) where they are cartographically modeled in the altitudinal gradient through multivariate analysis, taking into account the different geographic and topographic variables that influence the zonal variability of the species response. The results of the analyses and cartographic models show which variables are most determinant in the annual growth of the species and the distribution of its climatic response according to the variables considered.
Blessed Be the Fruit: santa Brígida y las resignificaciones religiosas en el referéndum sobre el aborto en Irlanda
Authors: Monzón Pertejo Elena , Bernad López Victoria
Published: December 2022

La fotografía de Olivia Harris, Blessed Be the Fruit, muestra a santa Brígida de Kildare, patrona de Irlanda, sujetando una pancarta en apoyo a la derogación de la Octava Enmienda de la Constitución de dicho país. Esta performance se inscribe en el clima previo al referéndum que tuvo lugar en 2018 en la República de Irlanda para decidir si se revocaba la ley que prohibía la interrupción voluntaria del embarazo. Esta fotografía y otras manifestaciones artísticas constituyen la base para realizar un estudio sobre la identidad nacional de Irlanda y sobre la figura de santa Brígida, personaje doblemente resignificado: primero por la apropiación del cristianismo, luego por el activismo feminista pro-elección.
Execrables o ejemplares, una deuda de la historiografía con la perspectiva de género. El caso de la princesa de los Ursinos
Authors: Carballeira Cendán Alba
Published: December 2022

El contraste entre las palabras execrable y ejemplar nos invita a reflexionar sobre el modo en que algunas mujeres han pasado a la historia. En un breve repaso sobre las bases de la historiografía y el nacimiento de la noción de agencia artística veremos cómo la construcción de su imagen no solo ha estado ligada al peso de su reputación; sino también a la falta de comprensión sobre muchas de las actividades que estas mujeres desempeñaron. Este artículo plantea la necesidad de seguir profundizando en la noción de agencia artística para entender cómo algunas de ellas encontraron en determinadas artes un margen dónde ejercer su poder. La revisión de algunas figuras desde la perspectiva de género es necesaria, no solo para restituir su imagen sino para devolverles el lugar que les corresponde en la historia del arte. El análisis del caso de la princesa de los Ursinos es el mejor ejemplo para comprender lo expuesto.

Authors: Ullauri-Ullauri Jaime Iván , Mauri-Majós Teresa
Published: December 2022

La formación de los aprendices de docente (AdD) en la actualidad demanda modelos de formación orientados a fortalecer la relación teoría-práctica y la reflexión sobre las situaciones o experiencias de la práctica preprofesional (PP). La presente investigación se desarrolló en la Universidad Nacional de Educación (UNAE). Comportó tres estudios de caso múltiple de los correspondientes grupos de AdD de quinto semestre de la carrera de Educación Básica (EB) en la Universidad Nacional de Educación en Ecuador y sus correspondientes parejas pedagógicas académicas de tutores (PPA), quienes participaron en un proceso de reflexión conjunta. Se llevaron a cabo dos entrevistas semiestructuradas en profundidad que fueron analizadas mediante un estudio temático deductivo.  Los resultados identifican las diferencias en las representaciones sobre la naturaleza de reflexión que enseñan entre los tutores que componen las PPA y subrayan la necesidad de formarles para una enseñanza de la reflexión más colaborativa.
Investigación en las prácticas de Educación Social. Conociendo el panorama actual desde un estudio bibliométrico
Authors: Mañas-Olmo Moises
Published: December 2022

El propósito de este estudio es mapear, a través de un estudio bibliométrico descriptivo, la literatura sobre investigación en las prácticas de Educación Social, especialmente en España y, de forma extensible, en una comparativa internacional, utilizando metadatos de 722 publicaciones indexadas en la base de datos Scopus desde la primera aparición en 1963. Los términos usados se refieren a trayectorias de crecimiento, tendencias, redes temáticas. Los principales resultados nos hablan de una tendencia al alza de la investigación internacional centrada en esta temática y de la forma en la que varias universidades españolas están tomando la iniciativa en este campo de investigación; al mismo tiempo, también sobre la forma en la que existe un estancamiento en cuanto a la repercusión de las publicaciones españolas en otros países, y de qué forma se diferencian 12 corrientes de investigación en las que temáticas como la formación del profesorado, los procesos de tutorización, el trabajo en equipo y/o los procesos de reflexión están copando las mayor parte de las publicaciones en este área. Se discuten los hallazgos y se concluye que debemos seguir impulsando y cuestionándonos el sentido que, como investigadores sociales, le damos al prácticum y, en consecuencia, el que ofrecemos al alumnado, al tiempo que debemos seguir incitando a nuevas líneas investigadoras.
IATROGENIC SYSTEMIC LYMPHEDEMA FOLLOWING MULTIPLE MYELOMA TREATMENT
Authors: Radu S. , Wilson J. , Bagwell A.K. , Meyers G. , Nauta A.C.
Published: December 2022

Lymphedema is a debilitating disease characterized by abnormal lymphatic drainage, either due to primary maldevelopment of the lymphatic system or to secondary injury. The clinical features of primary and secondary lymphedema differ, with primary lymphedema more often involving progressive bilateral lower extremity disease as compared to secondary lymphedema characteristically having more localized symptoms related to the origin of injury. This case presentation describes a patient who presented with bilateral lower extremity swelling, left greater than the right, with im- aging results to support the diagnosis of lymphedema. During the time he was followed in our clinic, our team witnessed rapid progression of his lymphedema despite compliance with conservative management. We believe that the primary mechanism of systemic damage to our patient's lymphatic system is the lenalidomide and bortezomib therapy prescribed to treat multiple myeloma. This review explores the relationship between lenalidomide, bortezomib, and lymphedema in efforts of understanding this unique pathology of iatrogenic lymphedema mimicking primary nature.

Comparative Analysis: Influence of Interest Rates on Returns of Real Estate Private Equity Index and Real Estate Public Equity Index
Authors: Sharma Manu
Published: December 2022

In this paper, we studied the influence of interest rates on a US-based real estate private equity index as well US Wilshire public equity REIT Index. The interest rates that are chosen as independent variables include Monthly LIBOR, Yearly LIBOR and the Federal Cost of Funds Index. The dependent variables include US-based real estate private equity index that includes quarterly returns of 1,035 real estate funds, including liquidated funds formed between 1986 and 2018. The other dependent variable is the US Wilshire REIT Index. The variance of returns of interest rates considerably influences the variance of returns of the US PERE Index, whereas variance of returns of interest rates doesn’t influence the variance of returns of the US Wilshire REIT Index. Also, the real estate index is positively correlated to interest rates and so rising interest rates influence the returns of US PERE Index in a positive manner. The study shows that private equity real estate investors should expect higher return as the cost of funds increase.

Published: December 2022

Valorization of CO2 captured from industrial processes is an important task for reaching climate and energy targets. The presented study addresses the use of CO2 for the production of ethanol, which can be used as a transport fuel. Hydrogen, produced by renewable energy technologies, is combined with CO2 to produce the synthetic fuel, thus making this approach attractive from a climate perspective. Aim of the study was to simulate the dynamics of the development of CO2-to-fuel solution, taking Latvia as the case. System dynamics modelling was used as the method for analysis. The model reflects several important feedbacks, such as relation between the captured CO2 emissions and the share of avoided CO2 emissions in transport due to fuel substitution, as well as investment in new production capacity of the ethanol. Use of avoided CO2 emission costs for funding of research and development (R&D) of the technology and direct subsidies for ethanol production is the analysed institutional aspect. The results show that if 15 % of the industrial CO2 emissions are used for ethanol production then circa 12 % of the transport CO2 emissions can be avoided. The share of avoided transport CO2 emissions are the most sensitive to unit costs of hydrogen production.
The adaptation and validation of the Techno-Work Engagement Scale (TechnoWES-9) in the case of Romanian employees
Authors: Balgiu Beatrice
Published: December 2022

The study looks into the validation and analysis of the psychometric properties of the Techno-Work Engagement Scale (TechnoWES-9) in the case of a sample of Romanian employees (N=280). The scale is based on the concept of work engagement and evaluates the well-being generated by the use of technology at the workplace. The tool includes three factors: techno-vigor, techno-dedication, and techno-absorption, each with three items. The factorial structure was verified through confirmatory factor analysis (CFA), and the reliability of the scale was examined from the perspective of its internal consistency. The concurrent validity was performed by associating scales that assess subjective well-being. The CFA supports the tri-factorial structure of the scale. The internal consistency of the total score is excellent. TechnoWES-9 is positively associated with subjective well-being, life satisfaction, and positive affect. None of the dimensions of the scale correlates with negative affect. The study suggests that the Romanian version of TechnoWES-9 is an adequate measure for the assessment of well-being of Romanian employees working in digital technology.

POLIVALENTNA STAMBENA ARHITEKTURA
Authors: Marjanović Sanja
Published: December 2022

Predmet istraživanja rada jeste kriti­čka analiza polivalentnosti stambenog prostora, kao i nje­gova primenljivost danas i ubuduće, kao odgovor na izazove koje postavlja brz razvoj i promena potreba ovdašnjih korisnika. Kao rezultat rada imamo uvid da celokupno stanje društva utiče i na nastanak i razvoj programa stanovanja i da oslikava i doba u kome nastaje. Novi oblici stanovanja i hibridne funkcije zahtevaju da budu smeštene unutar prostora koji mora biti dovoljno polivalentan da isprati njihove promene, pa projekat višeporodičnog stanovanja oslikava rezultat prethodno obavljenog istraživanja.

PRIMENA FOTOGRAMETRIJE RADI PODIZANJA IMERSIVNOSTI VIDEO IGARA
Authors: Mirčeski Kristina
Published: December 2022

Fotogrametrija predstavlja proces generisanja 3D modela korišćenjem velikog broja preklapajućih fotografija visoke rezolucije snimljene iz više uglova. Poslednjih godina industrija video igara prihvatila je fotogrametriju kao sredstvo za stvaranje vrlo detaljnog 3D sadržaja. Detalji koji se dobiju procesom fotogrametrije su upravo ono što stvara iluziju potpunog realizma i čine video igru imersivnom. Imersivnost u video igrama omogućava igraču video igre da virtuelni svet i likove unutar iste doživi kao realnost. Savremene igre oslanjaju se na senzorne stimulacije celog tela igrača zbog čega dizajneri video igara uključuju proširenu realnost i potpune simulacije virtuelne realnosti kako bi iskustvo igranja dostiglo svoj maksimum.

Round bars produced in industries are often found compromised with degree of straightness. In many small or medium size industries the problem of straightness is often addressed somewhat manually, which is indeed a slow and cumbersome process and lacks quality and precision. To speed up the process, it is necessary to go for mechanized system i.e. deployment of straightening machine. However, straightening machine indeed helps in perfect processing of operation and quality aspects which can be systematically controlled through various parameters involved in the process. An attempt has been made in this paper to look into the effect of helix angle of the cross-roll arrangement in the process based on the equations developed by former researchers in this field.
Phenytoin Toxicity with High Dose, Concomitant Ascorbic Acid Dosing
Authors: Schuh Michael J. , Mustain Kevin , Crosby Sheena
Published: December 2022

High dose ascorbic acid may increase risk of phenytoin toxicity. This case report demonstrates high phenytoin levels resulting in adverse drug reactions subsequent to dosing concomitantly with high dose vitamin C, or ascorbic acid (AA), as a precaution against acquiring corona virus (COVID) infection. This patient suffered from a major seizure when he ran out of his phenytoin prescription. Subsequent initiation of phenytoin and later addition of high dose AA resulted in truncal ataxia and falls with bilateral wrist and finger extension weakness. Phenytoin and AA were discontinued, and the patient returned to baseline on a new medication regimen of lacosamide and gabapentin without any other major seizures one year later.
Veränderungen der Ziele von Renaissance-Bewegungen vom 19. zum 21. Jahrhundert und mögliche Konsequenzen für die Ziele und Praxen ihrer Sprachpolitik
Authors: Kremnitz Georg
Published: December 2022

Im Folgenden möchte ich vor allem darauf hinweisen, dass sich die Kommunikationsbedingungen für weniger verbreitete, zumal dominierte Sprachen in den letzten Jahrzehnten verschlechtert haben. Dazu will ich zunächst kurz die weitgehend bekannten Ziele der Sprachrenaissance- Bewegungen, vor allem im 19. Jahrhundert, rekapitulieren, gehe dann auf einige allgemeine kommunikative Fragen ein, um von dort auf die Bedeutung neuerer technischer Entwicklungen für die Kommunikation zu kommen, teilweise daraus resultierende erneuerte Normkonzeptionen zu betrachten und in eine Einschätzung der aktuellen Situation einzumünden. Mein Text mündet in die Fragen: Welche Ziele können Renaissance-Bewegungen heute anstreben? Was gilt es zu vermeiden? Es kann sich in diesem Beitrag nur um eine vorläufige Skizze handeln, bei der ich mich auf die Situation in Europa konzentriere, allerdings denke ich, dass es einer gründlichen Diskussion im Hinblick auf die Möglichkeiten künftiger Sprach- und Sprachenpolitik vor allem dominierter Sprachen bedarf – zugleich muss sie auch die Möglichkeiten kommunikativen Verhaltens in einer sich zugleich globalisierenden und atomisierenden weltweiten Umgebung abschätzen. Zu dieser Diskussion möchte ich hiermit aufrufen.
Trastornos de control de impulsos: adicciones conductuales en la enfermedad de Parkinson
Authors: Parra-Medina Luis Enrique , Góngora-Alfaro José Luis
Published: December 2022

La enfermedad de Parkinson (EP) es un trastorno neurodegenerativo progresivo e incurable, que afecta con mayor frecuencia a personas de edad avanzada. Su diagnóstico es clínico y se basa en la aparición de varios síntomas motores como: temblor en reposo, bradicinesia, rigidez muscular e inestabilidad postural. Sin embargo, en las últimas décadas se ha reconocido que la EP también se manifiesta con síntomas no motores, entre los cuales se encuentran los trastornos de control de impulsos (TCI), los cuales se definen como conductas realizadas en forma impulsiva-compulsiva que pueden interferir en las principales áreas de funcionamiento de la vida de la persona, hasta el grado de causarle problemas físicos, psicológicos, sociales, jurídicos o financieros. Los TCI han sido vinculados con el uso de la terapia de reemplazo dopaminérgica, en especial de los agonistas de los receptores dopaminérgicos de tipo D3 como el pramipexol. Tradicionalmente cuatro tipos de comportamientos han sido reconocidos y clasificados como TCI y estos son: la hipersexualidad, las compras compulsivas, el juego patológico y la ingesta compulsiva de comida también llamada trastorno de atracones, sólo estos dos últimos están descritos en la edición más reciente del Manual Diagnóstico y Estadístico de los Trastornos Mentales (DSM-5). Por otro lado, existen otras manifestaciones que por sus similitudes neurobiológicas pueden ser consideradas también TCI o adicciones conductuales. En la presente revisión se presenta una somera descripción de las hipótesis acerca de la fisiopatología de los TCI, sus manifestaciones clínicas más importantes, los factores de riesgo para desarrollarlos y algunos abordajes terapéuticos.
