Pedagogical and decolonial affordances of group portfolio assessments for learning in South African universities
Authors:   University of the Witwatersrand, Fouche Ilse , Dison Laura , Andrews Grant , Prozesky Maria
Published: October 2021

Our paper discusses our recent experiences with designing effective assessments for challenging local contexts by using group work portfolio projects. South African universities are experiencing ever-increasing student numbers, diverse student bodies which have different language and literacy skill levels, and limited resources. Simultaneously, the need to decolonise university curricula and teaching and learning practices is being actively investigated across South Africa. In this paper, we discuss preliminary steps we have taken towards achieving this broader transformative agenda in the context of the massification of education, namely designing effective and decolonial assessments that support epistemological access and academic success, while at the same time challenging what counts as ‘powerful knowledge’ (Young and Muller, 2013) in the classroom. We argue that effective decolonial knowledge practices and deep critical engagement can be achieved by using group work portfolio tasks that align with assessment for learning principles (Carless, 2015). Using a design- based research approach, we describe three courses across two universities which have implemented portfolio-type group assessments. The preliminary findings suggest that group projects can yield rich and productive assessment for learning outcomes in large classes. In addition, portfolio projects that purposely interrogate diverse perspectives, knowledges and experiences can harness the diversity of groups to work towards decolonising the classroom.
Students' prior knowledge and threshold concepts in a first-year biology course: The lecturer as middleman
Authors:   University of the Witwatersrand, Dukhan Shalini
Published: October 2021

Constructive alignment focuses on alignment between curriculum, learning outcomes, teaching activities, and assessment. This study argues that for lecturers to set intended learner-centred outcomes, they need insight into students’ prior knowledge of a discipline’s threshold concepts. Little is known about how a syllabus’s assumptions of prior knowledge match up to what first- year students know. Yet this insight is necessary; new knowledge is built on existing knowledge, and learning is about moving to higher cognitive levels. To gain this insight, at the start of the 2018 academic year, 292 first year biology students voluntarily answered two formative, online multiple-choice assessments on DNA and RNA synthesis. The responses showcased their knowledge gaps versus what the syllabus expected. Data analysis of their responses was used to shape teaching activities. This study extends constructive alignment by showing how quality teaching in content-dense disciplines such as biology further requires that lecturers gauge students’ prior knowledge.

‘Pedagogies in context’ are explored through a national project working with academic staff developers and new academics' induction and transitioning into higher education. Causal-layered analysis is used to explore the interplay between academic staff, institutional development, and contextual influences in shaping professional learning processes. Data generated by the project’s steering committee (SC) reflects on pedagogical encounters with the NATHEP participants and conference delegates (HELTASA, 2019). The outcomes of each intervention were compared by reflecting on who was in the room and how epistemological and ontological depth in each engagement was achieved. The study was guided by whether pedagogies are mobile and agile, irrespective of context. The SC asserts that pedagogies in context are relative to the participants, purpose and the project embedded in a specific context to achieve the epistemological, ontological, methodological, and axiological breadth and depth required. The portability of pedagogies from one context to another depends on aspects intrinsic to knowledge generation, transformation and decolonisation, engagement, being and becoming, and socio-cultural and historical conditions. This is also incumbent on the agility and flexibility of facilitators to adapt their repertoire to draw on a suite of contextually relevant pedagogical approaches.
Engaging knowledge and the knower: Design considerations for emerging modes of academic staff development

Published: October 2021

Curriculum design is a complex undertaking that requires both epistemological and ontological work. While there is an increased need for academics to develop and strengthen their capacity to design curricula, particularly in the context of Universities of Technology, which have gone through an intense period of identity finding and re-curriculation, there is little support for academics involved in this kind of work. This paper reflects on four iterations of an academic staff development intervention aimed at supporting academics engaged in curriculum design and renewal, with a particular focus on designing flexible curricula. Using a learning design model along with eleven design considerations developed by Gachago, et al. (2020) for online academic staff development and Maton’s Legitimation Code Theory – in particular the dimension Specialization - we show how curriculum work and learning design is iterative, contextual and messy. Most importantly, it is relational and involves collective sense-making. We recommend that each context needs to be carefully considered when designing courses, both face-to-face and online, and design considerations (such as motivation, facilitation, structuredness, level of collaboration) impact strongly on participants’ engagement and consequently experiences.

The field of academic development in South Africa has produced a wealth of research over the thirty years of its existence. The impact of globalisation, however, has meant that local research in the field of academic development is often regarded as being of lesser value than knowledge from the global North and the so-called ‘best practices’ that emerge from it. The impact of uncritical acceptance of ‘best practice’ approaches from the global North is that understandings of teaching and learning tend to be divorcedfrom the context of practice. As a result, the application of such approaches often failsto accommodate the diverse learning needs of students and are not responsive to complex institutional and global South contexts.
Bhima Koregaon and the "Powers of the Other Shore"
Authors: Giri Saroj
Published: October 2021

In India, today, we are witness to the quiet rise of the figure of Mahar Sidnak, iconized and lionized as a warrior of the oppressed from the early nineteenth century. This is electrifying the anticaste struggle and energizing the militant youth, a source of inspiration as historical as it is mythical. Are material issues, or "real struggle," really so opposed to the question of the "mythical past"?
Partnership success factors: overcoming cultural misfit between tunisian SMEs and their french partners
Authors: Ben Kahla Karim , Khanchel Hanen
Published: October 2021

This paper proposes a conceptual framework to shed light on cultural issues in health crisis between Tunisian Small and medium-sized enterprises (SMEs) and their French partners. The Critical Success Factors (CSF) of a formalized management of cultural misfit can be considerable for researchers and practitioners: the steps of turning the page of the paradigm of cultural distance and address cultural difference from the point of view of mutual enrichment are worthy of interest. Indeed, the multivariate analysis proposes to go beyond this cultural paradigm to approach the cross-cultural management. Its goal is to formulate paths for reflection and research that will enrich the understanding of the difficulties encountered during the COVID-19 period in the dynamics of bringing together two entities from different national cultures. In order to achieve this objective, the correlational research design by Fey and Denison (2003) was adopted in this survey, using revised measurement scales from this work. This is because correlational research is concerned with studying a problem in order to analyse the relationship between cultural variables. The active consideration of cultural characteristics has a double advantage: it helps to alleviate tensions related to cultural challenges and capitalize on the CSF derived from the diversity of approaches. It proceeds from a detailed study of the cultural characteristics of the two partners, which will serve as a basis for a possible rapprochement in the future.
Trade Union Transformation and Informal Sector Organising in Uganda: The Prospects and Challenges for Promoting Labour-led Development
Authors: Schminke Tobias Gerhard , Fridell Gavin
Published: October 2021

Despite celebrations from governments, corporations and international financial institutions around increasing economic growth, the majority of the world’s urban labour force continues to work under informal conditions, lacking enforceable contracts, adequate earnings, democratic representation, secure employment and social protection. The pervasiveness of informal labour globally has given rise to numerous calls to adopt a wider and more diverse understanding of what constitutes labouring classes and what is required to organise them. Our case study assesses the outcomes and effectiveness of informal sector organising in Uganda, focusing on the transportation, market and textile sectors. Drawing on Guy Standing’s distinction between “business” and “community” unions and Benjamin Selwyn’s contrasting of “capital-centred development theory” (CCDT) and “labour-led development” (LLD), we argue that community unionist approaches are most effective in addressing the decent work deficit in the informal economy. Simultaneously, the trade unions face constant barriers to successful community organising in the informal economy that cannot be easily overcome without wider changes to the structural conditions under which union organisers must operate.

Rethinking Working-class Politics: Organising Informal Workers in Argentina
Authors: Bascuas Maisa , Felder Ruth , Logiudice Ana , Patroni Viviana
Published: October 2021

Our article engages with discussions about the implications of precarious work and its impact on workers’ capacity to organise by analysing the case of Argentina’s Confederation of Popular Economy Workers (CTEP, Confederación de Trabajadores de la Economía Popular). The organisation was created in 2011 with the aim of representing a broad and heterogeneous group of workers in varying conditions of informality, precarious self-employment and workfare programmes. We trace the history of the organisation and analyse its development by focusing on the role of social assistance as a crucial expression of the changing relations between precarious workers and the state. Social assistance has provided some resources for addressing the reproduction needs of precarious workers and of the territories in which they live, and also the material means through which an organisation like CTEP has sought to consolidate its political work among precarious workers. Nonetheless, social assistance has also worked as a means to circumscribe broader demands for change into issues to be addressed through social policy. Our argument is that central to CTEP’s trajectory as an organisation of precarious workers was its attempt to break away from the narrow confines of social assistance, pushing for changes that would allow its members to gain some autonomy both materially and institutionally.

PANDEMIA E LAZER: os reflexos da pandemia nos cotidianos de lazer das periferias urbanas
Authors: Da Silva Lourenço Cezar , Nascimento Diogo Silva Do , Sales Marcelo Ribeiro , Souza Rafaela Goltara
Published: October 2021

Diversas periferias no país são marcadas historicamente por ausências, precariedade dos serviços públicos e pelas narrativas sobre violência e pobreza divulgadas pela imprensa de forma constante há muitas décadas. Essas narrativas oficializadas sobre esses territórios imperam como obstáculos aos moradores, que continuam sendo estigmatizados e excluídos socialmente. Nestes tempos de pandemia, a situação parece ter se agravado. Falta de leitos para  a população mais pobre, materiais de higiene e até mesmo a diminuição drástica da renda tem tensionado esse período nos territórios periféricos. No entanto, mesmo com tantas problemáticas, muitos moradores de periferias têm encontrado dificuldade de abrir mão dos espaços de lazer, mesmo com medidas de distanciamento social. Nesse sentido, as resenhas nos botequins, as peladas no campo de várzea, o bate papo nas feiras se apresentam como grandes adversários nessa luta contra a Covid-19. Assim, buscando entender as relações e a importância que esses territórios do lazer representam, buscamos investigar três periferias nos Estado de Minas Gerais e Rio de Janeiro. Nesse sentido, pesquisamos os bairros de Justinópolis em Ribeirão das Neves- MG, Lote XV em Belford Roxo-Rj e o Conjunto de Favelas da Maré no Rio de Janeiro- RJ.   O trabalho analisou a maneira como se configuraram as sociabilidades e identidades tecidas através das experiências fomentadas nesses espaços de lazer, indicando a resistência dos moradores em abrir mão, mesmo em um momento de pandemia, desses espaços de lazer. Esta pesquisa utilizou a abordagem etnográfica por meio de observações entendendo esses territórios do lazer como “Pedaços” marcados por códigos, pertencimentos e identificações peculiares no contexto periférico, como diz José Magnani.
Informing California's Plan to Enhance HIV Screening in the Ending the HIV Epidemic Initiative
Authors: Leibowitz Arleen , Tan Diane
Published: October 2021

The CDC recommends that everyone have at least one HIV test in their lifetime. However, analyses of California Health Interview Survey data showed that in 2017 only half of Californians had ever received an HIV test. Non-Hispanic Black (64.8%) and Hispanic adults (54.7%) had higher lifetime testing rates than non-Hispanic White adults (48.8%). In multivariable analyses non-Hispanic African American adults had twice and Hispanic adults 1.2 times the odds of lifetime HIV testing as non-Hispanic White adults. The CDC recommends annual HIV testing for higher-risk individuals. Independent of race/ethnicity, heterosexual men with multiple sex partners had lower annual testing rates than other high-risk individuals. Annual testing was unrelated to education level and poverty, but was related to number of doctor visits. HIV screening rates among heterosexual men with multiple partners could be increased by targeting HIV screening to non-medical settings in California's eight Ending the HIV Epidemic counties.
An Interpersonal Approach to Social Preference: Examining Patterns and Influences of Liking and Being Bothered by Interpersonal Behaviors of Others
Authors: Du Tianwei V. , Thomas Katherine M. , Lynam Donald R.
Published: October 2021

Personality disorders are rooted in maladaptive interpersonal behaviors. Previously, researchers have assessed interpersonal behaviors using self-ratings of one's own behaviors and third-person ratings of dyadic interactions. Few studies have examined individuals' perceptions of others' interpersonal behaviors. Using a sample of 470 undergraduate students, the authors examined patterns of interpersonal perception as well as influences of these patterns on psychological functioning. Findings showed that people tend to like interpersonal behaviors that are similar to their own and become bothered by behaviors that are the opposite of their own. Such a pattern is particularly characteristic on the warmth dimension and is consistent across different levels of closeness of the relationship. The authors also found small but significant effects of interpersonal perception on personality and general psychological functioning, above and beyond effects of individuals' own interpersonal traits. Such findings highlight the importance of including perceptions of others in investigating interpersonal dynamics when understanding personality disorders.
Microbial proportion and heterotroph CO2 flux from drainage peatland under oil palm plantation

Published: October 2021

The difference in soil layer can affect heterotroph respiration that means CO2 fluxes from microbial decomposition in peatlands. Oil palm plants release root exudates transported to other places, i.e., shrub, by water movement, which can stimulate microbial activity. This study was conducted to learn the effects of differences of the soil layer and distance from the trunk in drainage peatland under oil palm plantation on total bacteria, fungi, cellulolytic bacteria, ligninolytic fungi, and heterotroph fluxes CO2, then compared to a shrub. Heterotroph respiration decreased with soil layer depth, where at the layer 0-20 cm released amount of CO2 as much 6.07 + 1.76, at 20-40 cm was 5.18 + 0.50, and at 40-60 cm 5.27 + 1.20 mg CO2 100 g-1 day-1, and tended higher than in shrub where a layer of 0-20 cm released 5.51 + 1.69, then decrease at 20-40 cm to 4.83 + 1.38, and at 40-60 cm 4.30 + 1.08 mg CO2 100 g-1 day-1. Total bacteria (107 CFU g-1) and fungi (105 CFU g-1) were higher than total cellulolytic bacteria (103 CFU g-1) and ligninolytic fungi (102 CFU g-1) in both under oil palm plantation and shrub. Organic acids affected the abundance of total bacteria and fungi but did not affect cellulolytic bacteria and ligninolytic fungi on both sites, as shown by a lower population and low cellulose and laccase enzymes. These findings showed that heterotroph CO2 flux tended higher in oil palm plantations and lignocellulolytic microbes are not the only source of heterotroph respiration.
Treatment of compost as a source of organic material for bacterial consortium in the removal of sulfate and heavy metal lead (Pb) from acid mine drainage
Authors: Fahruddin F , Nafie Nursiah La , Abdullah Asadi , Tuwo Mustika , Awaluddin A
Published: October 2021

Acid mine drainage can pollute the environment because it is acidic and contains toxic heavy metals. The purpose of this research was the application of a bacterial consortium to remove sulfate and reduce heavy metal lead (Pb) in acid mine drainage. The application was done in the bioreactor for acid mine drainage treatment that was treated with compost. Observations were made every five days and included observation of total bacterial growth using the Standard Plate Count (SPC) method, determination of sulfate content by gravimetry, determination of pH by use of pH meter, and determination of the concentration of heavy metal Pb using the AAS method. As a result, it was obtained that the treatment of non-sterile compost in acid mine drainage was able to reduce the initial heavy metal concentration of Pb of 84% and reduce the sulfate content by 72%, along with increasing pH and an increase in total bacterial growth. Meanwhile, sterile compost treatment was only able to reduce the Pb content by 63% and sulfate by 54%. This result indicates that the addition of compost is more effective than the treatment of sterile compost.
Assessment of organic carbon contamination in the unsaturated zone: a case of Yogyakarta City, Indonesia
Authors: Hendrayana Heru , Putra Doni Prakasa Eka , Priambodo Yosua
Published: October 2021

In 1997, groundwater pollution was caused by a diesel leak at the Yogyakarta City Railway Station. People in the south of the railway station discovered the presence of diesel in dug wells in 2001. The existing diesel is still found in dug wells even though the pollutant source had been removed. The current source of pollution comes from diesel residues trapped in the unsaturated zone. Understanding the distribution and concentration of diesel in the unsaturated zone is the goal of this study. In this study, diesel concentration was measured based on Total Organic Carbon (TOC) levels. The research was conducted through shallow core and deep core drillings. Shallow core drilling was done at 14 points with a depth of 50 cm, and deep core drilling was done at nine drilling points with a depth of 15-17 m. 14 shallow core drilling samples were taken from a depth of 30 and 50 cm and nine deep core drilling samples were taken from a depth of 4-5 m and 10-11 m. The lithology logs in both drills were tested for diesel odour and TOC levels using the Soli TOC tool. Based on the test results, the smell of diesel was found at a depth of 10 to 15 m. TOC levels in the unsaturated zone ranged from 340 to 90,870 mg/L. TOC levels >30,000 mg/L were dominant at shallow depths even though they did not smell like diesel. At a location close to the source of the diesel tank leak at a depth of 4-5 m, the measured TOC level was 30,100 mg/L. The results showed that there were zones of high TOC levels associated with diesel odour layers. The zones existed because of the infiltration and percolation processes that had carried surface water and diesel pollutants and eventually moved horizontally following groundwater flow.

Published: October 2021

In the Peruvian Amazon, large area of primary forest have been deforested by Artisanal and small-scale gold mining (ASGM). Vetiveria zizanioides (Poaceae) is considered an excellent plant for the ecological restoration of degraded lands. The present study aimed to analyze the growth and survivorship of V. zizanioides in degraded soils by gold-mining in the Peruvian Amazon (Madre de Dios). The experiment was conducted under greenhouse conditions, and it followed a randomized complete block design with four treatments (substrates). The substrates were sand (mining), sand+pebbles (mining), forest soil, and amended soil. We evaluated the survivorship, shoot, tiller, and biomass production of V. zizanioides for two months. Univariate analysis of variance was used to detect differences among treatments. Fifteen days after experiment establishment, V. zizanioides survivorship was significantly higher in ASGM substrate 2 (sand+pebbles) than in other substrates, following the order of ASGM substrate 1 (sand) > forest soil > amended soil. However, at the end of the experiment, we did not find a significant difference on survivorship in subsequent assessments, and the total biomass per plant was lower in mining substrates than in non-mining substrates. The total biomass was significantly higher in amended soil than in other substrates, with yields between 1.7 and 3.6 times more biomass in amended substrate than in mine substrates. The soil substrate type significantly affected the survivorship, number of shoots, and biomass of V. zizanioides. The research results can provide a reference for remediation of degraded soils by gold-mining in the Peruvian Amazon.
Resilience in Global Value Chains: A Systemic Risk Approach
Authors: Ibrahim Sherwat E. , Centeno Miguel A. , Patterson Thayer S. , Callahan Peter W.
Published: October 2021

Global value chains (GVCs) have increased efficiencies, accelerated production, reduced costs, and increased wealth and opportunities for workers, firms, nations, and the global economy as a whole. However, the benefits and efficiencies provided by these GVCs come at the cost of increasing risks. This is largely because the emergence and evolution of GVCs have been enabled by advancements in globalization, complexity, and technology, as well as the development of critical global systems that underpin these industries—such as communication, transportation, financial systems, and others. GVCs are thus only as stable as these underlying global systems upon which they depend, and are vulnerable to potential shocks to these systems.

The COVID-19 pandemic and other recent global interruptions in GVCs have demonstrated the importance of applying a systems theory approach, which allows us to identify—and eventually begin managing for—the multidimensional risks that these global industries face. Studying the stability and reliability of these global industries requires not only an understanding of risks within just the GVCs but also an awareness of vulnerabilities in numerous critical underlying systems that form the infrastructure of GVCs and the global economy. As examples, we examine six such underlying systems: health care and public health, supply chain and logistics, technology and cyber, finance, sociopolitical, and the environment. Each of these examples illustrates that disruptions, fragilities, or failures in critical underlying systems can dramatically impact GVCs as a whole and make the geographic regions in which these systems are vulnerable less attractive to industry investment and expansion.

Introducing methodologies and concepts from systems theory, we illustrate that these underlying global systems that expose GVCs to vulnerabilities are complex adaptive systems (CAS). As systems of systems composed of CAS, these GVCs consequently also can be modeled as CAS. We argue that not only does this CAS perspective help to mitigate the multilayered GVC risks through better understanding and the application of CAS tools like “adaptive management,” but it also empowers policymakers to better attract GVCs to their borders by prioritizing the creation of more resilient underlying systems.
Sounding the “Spirit of My Silence”
Authors: Farrell Natalie
Published: October 2021

Sufjan Stevens’s 2015 album Carrie and Lowell threw indie rock fans into collective mourning with its sonic depiction of feeling so much to the point of experiencing an overwhelming affective nothingness. Written as an elegy for Stevens’s mother, the album performs Stevens’s loss by creating a static soundscape punctuated by moments of stark sonic absence. Some moments evoke the emotionally ineffable (rhythmic stutters between phrases), some occupy a sonically liminal space with white noise negating silence, and others are calls to physical action (flipping over the LP) that literally give the listen pause.

This paper places an autoethnographic encounter with a Carrie and Lowell pre-release “silent listening party” in conversation with Roland Barthes’s theory of affect and grief as originally developed in Camera Lucida: A Note on Photography. This paper explores the possibility that Barthes’s theory offers an infrastructure for approaching affect and musical listening by highlighting the ways in which the individual functions as an affective archive, navigating culturally-coded and pre-cognitive physiological responses to aesthetic objects. Drawing upon Elizabeth Hellmuth Margulis’s work on structured silences, this paper argues that moments of foregrounded silence in Carrie and Lowell provide musical analogies for Barthes’s punctum of time and death.
Immersed in Pop
Authors: Bresler Zack
Published: October 2021

In 2019, Dolby Atmos Music launched on Tidal HiFi and Amazon Prime Music HD, integrating 3D sound with music streaming services for the first time. This is one of several recent incursions by popular music into immersive and interactive mediums, which also includes technologies such as virtual reality and 360-degree video. As immersive productions become more normal in popular music, they are increasingly critical to examine. How are aesthetic features of pop compositions altered or maintained in these productions? And how do these different spatial mediums affect compositional design, subject positioning, artists’ performativity, and staging? This article aims to address these questions by presenting a model for 3D music analysis that relates various notions of music technology and production to musicological concepts on performance environment, staging, and subject position. This model is then demonstrated in a hermeneutic close reading of the song ‘Blinding Lights’ by R&B superstar The Weeknd, which was released in both stereo and Dolby Atmos mediums in 2019. The goal of the analysis is to demonstrate some of the ways different mediums impinge on various interpretive stances and the relationship between the performer and listener in immersive popular music.
Analysis of Mechanical, Microstructural Properties and Weld Morphology of A-TIG Welded AH-36 Marine-Grade Steels with Oxide and Duplex Flux Coating
Authors: Kumar K. Vijaya , Ramanaiah N. , Bhargava Rama Mohan Rao N.
Published: October 2021

The current study investigates the metallurgical, mechanical properties and weld morphology of AH36 marine grade steel (with a thickness of 8 mm) by activated-tungsten inert gas  (A-TIG) butt joints, with the application of different fluxes (MoO3, V2O5, and duplex of MoO3 and V2O5) at various process parameters. The welding speed was kept constant at 120 mm/min, and current varied from 160 A to 220 A uniformly to optimise process parameters to achieve desired mechanical properties, weld morphology, and lowest possible heat input. The study also focused on comparing tensile strength, impact strength, and microhardness, heat input during welding, weld bead depth and width between conventional TIG welding and activated flux TIG welding processes at various operation parameters. Tensile results reported that fracture occurs at the base region in ordinary TIG welding and the activated tungsten inert gas welding process. It was noticed that a higher depth to width ratio attained MoO3 and V2O5 duplex flux coated weldments. There is evidence that the depth of weld joints is enhanced because of stable arc, Marangoni effect, and arc constriction. Microhardness results reported that the fusion zone has a higher microhardness in the activated tungsten inert gas welding than the ordinary TIG welding. It was concluded that out of all fluxes, MoO3 and V2O5 duplex flux coating produce better butt welds of AH36 steel.

Published: October 2021

Der Beitrag erläutert, inwiefern die Methode der quantitativen Textanalyse ein wesentliches Mittel zur betriebswirtschaftlichen Effizienzsteigerung sein kann. Dabei geht der Artikel über die Nennung von Chancen und Risiken des Einsatzes von künstlicher Intelligenz/Big Data-Analysen hinaus, indem der Beitrag praxisorientiert wichtige Entwicklungen im Bereich der quantitativen Inhaltsanalyse aus der wirtschaftswissenschaftlichen Literatur herleitet. Nachfolgend unterteilt der Artikel die wichtigsten Schritte zur Implementierung in (1) Datenerhebung von quantitativen Textdaten, (2) Durchführung der generischen Textanalyse und (3) Durchführung des Natural Language Processing. Als ein Hauptergebnis hält der Artikel fest, dass Natural Language Processing-Ansätze zwar weiterführende und komplexere Einsichten bieten, jedoch das Potenzial generischer Textanalyse - aufgrund der Flexibilität und verhältnismäßig einfachen Anwendbarkeit im Unternehmenskontext - noch nicht ausgeschöpft ist. Zudem stehen Führungskräfte vor der dichotomen Entscheidung, ob programmierbasierte oder kommerzielle Lösungen für die Durchführung der Textanalyse relevant sind.

Während die Geldpolitik in der Eurozone die Aufgabe hat Preisstabilität zu gewährleisten, zielt die makroprudenzielle Politik auf die Erhaltung der Finanzstabilität. Da beide Politikbereiche einander beeinflussen und (unerwünschte) Nebenwirkungen in Bezug auf das Ziel des jeweils anderen haben können, ist ihre Koordination relevant. In Hinblick auf die optimale Ausgestaltung dieser Koordination gibt es divergierende Ansichten. Insbesondere ist umstritten, ob die Geldpolitik Finanzstabilitätsziele in ihren geldpolitischen Entscheidungen berücksichtigen sollte.
Das WiSt-Jubliäumsfragespiel: 19 aus 71
Authors: Weißenberger Barbara E.
Published: October 2021

1971 wurde die Zeitschrift WiSt von den Herausgebern Prof. Dr. Dr. h.c. Erwin Dichtl und Prof. Dr. Dr. h.c. mult. Otmar Issing ins Leben gerufen.In unserer Serie beantworten Autorinnen und Autoren der Zeitschrift 19 Fragen aus 71. Warum gerade 19 aus 71? Die Zahlen sind an das Jahr 1971 angelehnt. Für den Fragebogen haben wir uns unter anderem den „Proust´schen Fragebogen“ zum Vorbild genommen. Ursprünglich ist dieser ein beliebtes Gesellschaftsspiel, das einen fast unendlichen Spielraum von Antwortmöglichkeiten gibt: Die Person kann alles über sich preisgeben oder ein Rätsel bleiben. Gedacht ist es als ein Spiel, ein launiger Zeitvertreib, um einen kurzen, persönlichen Blick hinter den offiziellen Autorenlebenslauf zu werfen und unsere Autorinnen und Autoren etwas näher kennenzulernen.Aus 71 Fragen wählen wir für jeden Teilnehmer zufällig 19 Fragen aus. Von diesen können die Autorinnen und Autoren insgesamt fünf Fragen mit solchen aus dem Pool der übrigen 52 Fragen austauschen. Der vollständige Fragenkatalog ist auf unserer Homepage abrufbar. In diesem Heft fragen wir Prof. Dr. Barbara E. Weißenberger.

Geschäftsmodelle für den Betrieb von Elektro-Ladeinfrastrukturen
Authors: Hausladen Iris
Published: October 2021

Die Realisierung von ökologischen Verkehrskonzepten, wie sie u. a. die Elektromobilität darstellt, birgt nicht nur technische Herausforderungen, sondern gleichermaßen ein Bündel an z. B. ökonomischen und infrastrukturellen Fragestellungen. Zentraler Erfolgsfaktor ist hier das Vorhandensein eines bedarfsgerechten Ladenetzwerks. Der vorliegende Beitrag entwirft einen Rahmen zur Geschäftsmodellentwicklung für den Betrieb von Ladeinfrastrukturen, aufbauend auf dem Leitprinzip der „Symbiose“.
Das Zipfsche Gesetz: Statistische Gemeinsamkeiten in Zeitungsartikeln
Authors: Vogt Martin , Lübke Karsten
Published: October 2021

Schussbereit im Klassenzimmer! Wie ich glaube, den Fußball zu retten! Elbphilharmonie: Klingt ziemlich traurig! Brexit: No Deal, Tag eins! Das sind nur vier exemplarische Schlagzeilen in einer großen Online Zeitung. Zeitungen enthalten Nachrichten aus verschiedenen Themengebieten. Zur besseren Übersichtlichkeit sind Zeitungen deshalb häufig nach Ressorts gegliedert, welche jeweils ein bestimmtes Gebiet bearbeiten. Hierzu zählen klassischerweise auch die Ressorts: Politik, Wirtschaft, Kultur und Sport. Journalisten müssen für jedes Ressort ein spezifisches Wissen haben. Die Inhalte unterscheiden sich deutlich. Dennoch gibt es statistisch gesehen Gemeinsamkeiten. Diese kann man auch bei ganz anderen betriebswirtschaftlichen Daten entdecken, etwa im Zusammenhang mit der Größe von Firmen.
PREDICTORES DE LA EFICACIA DE RECEPCIÓN EN VOLEIBOL MUNDIAL MASCULINO U-21 Y ABSOLUTO
Authors: González-Silva J. , Fernández-Echeverría C. , Conejero M. , Moreno M.P.
Published: October 2021

El objetivo de la investigación fue conocer las variables de recepción que predecían su eficacia, en diferentes niveles de juego (U-21, absoluto) en voleibol masculino. La muestra del estudio estuvo compuesta 3442 acciones de recepción, de las cuales 1894 corresponden a categoría U-21 (U-21 Men´s World Championship) y 1548 a categoría absoluta (Absolute Men´s World Championship). Las variables del estudio fueron: función del receptor, desplazamiento previo del receptor, tipo de recepción, posición del receptor, técnica de recepción, zona de recepción, eficacia de recepción. El análisis de regresión logística multinomial mostró que, el desplazamiento previo del receptor y la técnica de recepción fueron predictoras en ambas categorías, U-21 y absoluta; el tipo de recepción y zona de recepción fueron predictoras únicamente en U-21; la posición del receptor fue predictora únicamente en absoluta. Dicha información puede ayudar al proceso de entrenamiento favoreciendo el diseño de tareas concretas para cada nivel de juego.
¿ESTÁN PREPARADOS LOS MÉDICOS ESPAÑOLES DEL MAÑANA PARA COMBATIR LA INACTIVIDAD FÍSICA?
Authors: Perez-Lasierra J.L. , Hernández-Vicente A. , Comeras-Chueca C. , Casajús-Mallén J.A.
Published: October 2021

El objetivo del estudio fue averiguar que conocimientos tenían los estudiantes de medicina españoles sobre las recomendaciones actuales de Actividad Física (AF) de la Organización Mundial de la Salud (OMS). Un total de 334 estudiantes de medicina (2º-6º curso) de 29 universidades españolas cumplimentaron un cuestionario de conocimientos sobre las recomendaciones de AF de la OMS. El 100% de los encuestados afirmaron que recomendar AF es una parte importante del trabajo de un médico, pero sólo un 34,1% se sentían preparados para ello. Un 85,0% y un 72,5% desconocían las recomendaciones de AF de la OMS para adultos y niños respectivamente. El 94,3% demandaron una mayor formación académica en AF, siendo el método de preferencia la asignatura optativa. La falta de conocimiento sobre las recomendaciones de AF de los estudiantes de medicina españoles es evidente y alarmante. Aumentar la formación en dichos contenidos mediante asignaturas optativas podría revertir esta situación.
TRATAMIENTO DE LA LATERALIDAD EN GIMNASIA RÍTMICA: ESTUDIO CENTRADO EN ENTRENADORAS Y ENTRENADORES
Authors: Estrada-Marcén N. , Redondo-Laencina P. , Casterad-Seral J. , Cid-Yagüe L.
Published: October 2021

Durante muchos años se han estudiado los factores de los que depende la lateralidad humana, no habiéndose podido establecer ningún resultado concluyente hasta el momento. El deporte es un ámbito en el que frecuentemente se pretenden realizar cambios en la lateralidad. Encontramos estudios que afirman que la dominancia lateral se puede cambiar mediante el entrenamiento y la aplicación de técnicas de modificación de la conducta motriz (Bilbao & Oña, 2006). Pretendemos obtener una visión general del tratamiento de la lateralidad en el entrenamiento de la Gimnasia Rítmica, basado en las opiniones y experiencias de entrenadoras y entrenadores. Para la recogida de información se diseñó un cuestionario, participando 83 personas. El análisis permitió describir el tratamiento que en el entrenamiento de Gimnasia Rítmica se da a la lateralidad. El uso de los miembros contralaterales propiciado en el entrenamiento es relativamente frecuente (60%), pero no suele producir cambios en el lado hábil.
PORTERÍA VACÍA: SU INFLUENCIA EN EL CAMPEONATO MUNDIAL DE BALONMANO MASCULINO 2019
Authors: Flores-Rodríguez J. , Ramírez-Macías G.
Published: October 2021

El objetivo de la presente investigación fue conocer el impacto que ejerce en el desarrollo del juego la nueva norma, que permite la sustitución del portero por un jugador de campo (jugando a portería vacía). Empleando un instrumento de observación ad hoc se registraron todos los ataques realizados en los partidos correspondientes a la fase final del Campeonato Mundial masculino de Balonmano celebrado en 2019. Tras un análisis descriptivo, se aplicó la técnica de coordenadas polares para conocer los patrones de conducta que emergen en una situación de 6 vs. 6, según se utilice o no el recurso de la portería vacía. Los resultados indican que la nueva norma se utiliza primordialmente en inferioridad numérica, provocando diferentes comportamientos en las fases de ataque y repliegue defensivo. Finalmente, hay que destacar que conocer las nuevas tendencias del juego puede ayudar a optimizar los programas de aprendizaje y rendimiento deportivo.
FUTURO ESTÁ EN LA COMEDIA ROMÁNTICA DE HOLLYWOOD: LAS CHICAS MODERNAS DE MANUEL ROMERO
Authors: Morales Iván
Published: October 2021

En este artículo estudio un grupo de películas realizadas por Manuel Romero entre 1938 y 1942, donde se apropió de la comedia romántica hollywoodense para incorporar al cine argentino la figura de la chica moderna. Cercana a la heroína indisciplinada de la screwball comedy (un género que, justamente, se destaca por tener a mujeres independientes como protagonistas), la chica moderna romeriana posee un carácter desestabilizador que le permite alterar las lógicas de clase, género e identidad nacional prefijadas, moviéndose con libertad entre ricos y pobres, hombres y mujeres, costumbres argentinas y cosmopolitas.
