Kants Philosophie des Schönen
Authors: Berger Larissa
Published: April 2022

In der preisgekrönten Arbeit von Larissa Berger mit dem Titel „Kants Philosophie des Schönen“ wird eine Analyse und Rekonstruktion des kantischen Texts „Analytik des Schönen“ entwickelt. Mittels der Methode der kommentarischen Interpretation wird eine sehr textnahe und detaillierte, zugleich aber analytisch-argumentative Interpretation der kantischen Schönheitstheorie entwickelt. Dazu werden Kants Thesen, Definitionen und Argumente klar analysiert und rekonstruiert, sodass die Theorie insgesamt verständlicher und damit auch anschlussfähiger für aktuelle Debatten wird. Das Resultat ist ein umfassender Kommentar, der entweder in Gänze oder als eine Art kommentierendes Nachschlagewerk für einzelne Paragraphen, Begriffe und Thesen genutzt werden kann.
Versuch über Gelassenheit
Authors: Penner Peter
Published: April 2022

The strangeness of the Other is answered by an ontological model of serenity as resignativity.

Serenity means abdication of the self and its opening towards the Other. Because the difference of subjectivity and alterity shows up in subjectivity itself as a dialectic of giver and receiver, we as subjects are required to act as striving and letting go. But the duality of action presupposes the unity of being, which is the condition of the obligatedness of subjectivity through alterity and of the commitment of subjectivity for alterity. This determinateness of being forms the foundation of a hermeneutics which grasps the task of self-understanding of subjectivity as self-limitation.
Zur politischen Ökonomie kommunaler Unternehmen
Authors: Boll David
Published: April 2022

Do misaligned incentives arise between municipal enterprises, municipal politics and citizens? This study applies approaches from public choice theory to information problems and incentive inefficiencies in municipal enterprises. Using multivariate regression analyses, the author empirically examines the influence of municipal policy on the investment behaviour of the enterprises in question: 8,685 companies from 3,237 municipalities taken from all 13 German federal states during the period 2002–2014. The study’s key finding is that the fragmentation of interests in municipal councils has a negative influence on the enterprises’ investments per capita, which potentially indicates investment blockades.
Kartellschadensersatzverfahren am Justizstandort Deutschland
Authors: Loy Christoph
Published: April 2022

Follow-on cartel damages proceedings concern a large number of German courts, which have to compete with other forums for effective proceedings. This raises the questions of what actually determines the effectiveness of such proceedings and how Germany is doing in this respect as a forum. To answer these questions, the author conducted a survey among lawyers to determine the decisive parameters. In order to establish a status quo for these parameters, this is followed by a practical analysis of, among others, all decisions published in the period under review, as well as a presentation of possible impulses for increases in effectiveness from the established forum England.

The study focusses on the tension between police public relations in social media and the freedom of assembly. For this purpose, legal observations are linked with theoretical questions of constitutional law and legal solutions are offered. Leading criterion for the discussion are potential encroachments on fundamental rights and the associated requirements for the reservation of the law. Existing norms in law are analysed with regard to their applicability as standards of competence. Finally, the constitutional requirements for the design of this information activity are considered, whereby the cooperation requirement under assembly law is unfolded in the digital sphere of discourse.
Die Erbenuntreue
Authors: Zierden Johannes
Published: April 2022

This work addresses the issue of the duty of the heir to look after the assets of his co-heirs. The spectrum of opinions is presented and the civil and criminal law classification of the estate within the community of heirs is analysed. Building on this, the individual characteristics of an heir's duty to take care of property under Section 266 of the German Criminal Code are examined, outlining the understanding and requirements profile in case law and literature. In particular, the criterion of the heir's scope for decision-making in estate care is evaluated in detail and a separate assessment approach for determining the specific independence is elaborated.

Authors: Tietjen Udo
Published: April 2022

The topic selection of judges has become topical again in Germany because the coalition agreement of the governing parties includes a review of the selection of federal judges. The book examines the selection of judges in a European comparison. The selection of federal judges plays an important role in this context. It is criticised for being non-transparent and dominated by party politics. On the basis of the German constitution and comparative law, concrete proposals for improvement are formulated - also with regard to the election of federal judges. The book is aimed at all those who deal with judicial policy and are interested in more transparency, justice and equal opportunities within the judiciary.
Fuzzy Perceptron Learning for Non-Linearly Separable Patterns
Authors: Kishor Duggirala Raja
Published: April 2022

Perceptron learning has its wide applications in identifying interesting patterns in the large data repositories. While iterating through their learning process perceptrons update the weights, which are associated with the input data objects or data vectors. Though perceptrons exhibit their robustness in learning about interesting patterns, they perform well in identifying the linearly separable patterns only. In the real world, however, we can find overlapping patterns, where objects may associate with multiple patterns. In such situations, a clear-cut identification of patterns is not possible in a linearly separable manner. On the other hand, fuzzy-based learning has its wide applications in identifying non-linearly separable patterns. The present work attempts to experiment with the algorithms for fuzzy perceptron learning, where perceptron learning and fuzzy-based learning techniques are implemented in an interfusion manner.
Research Progress of Ionic Thermoelectric Materials for Energy Harvesting
Authors: Zhang Jianwei , Xiao Ying , Lei Bowei , Liang Gengyuan , Zhao Wenshu
Published: April 2022

Thermoelectric material is a kind of functional material that can mutually convert heat energy and electric energy. It can convert low-grade heat energy (less than 130°C) into electric energy. Compared with traditional electronic thermoelectric materials, ionic thermoelectric materials have higher performance. The Seebeck coefficient can generate 2–3 orders of magnitude higher ionic thermoelectric potential than electronic thermoelectric materials, so it has good application prospects in small thermoelectric generators and solar power generation. According to the thermoelectric conversion mechanism, ionic thermoelectric materials can be divided into ionic thermoelectric materials based on the Soret effect and thermocouple effect. They are widely used in pyrogen batteries and ionic thermoelectric capacitors. The latest two types of ionic thermoelectric materials are in this article. The research progress is explained, and the problems and challenges of ionic thermoelectric materials and the future development direction are also put forward.

The direct impacts cum problems resulting from oil pollution have led to economic depravations, destruction of farmlands, and livelihood of the people. This chapter explores the problems of oil pollution in the Niger Delta, the roles of newspapers in the coverage of oil pollution in Nigeria, environmental communication in Nigeria, and framing oil pollution in Nigerian newspapers.
Cognitive Visual Tracking of Hand Gestures in Real-Time RGB Videos
Authors: Golash Richa , Kumar Jain Yogendra
Published: April 2022

Real-time visual hand tracking is quite different from commonly tracked objects in RGB videos. Because the hand is a biological object and hence suffers from both physical and behavioral variations during its movement. Furthermore, the hand acquires a very small area in the image frame, and due to its erratic pattern of movement, the quality of images in the video is affected considerably, if recorded from a simple RGB camera. In this chapter, we propose a hybrid framework to track the hand movement in RGB video sequences. The framework integrates the unique features of the Faster Region-based Convolutional Neural Network (Faster R-CNN) built on Residual Network and Scale-Invariant Feature Transform (SIFT) algorithm. This combination is enriched with the discriminative learning power of deep neural networks and the fast detection capability of hand-crafted features SIFT. Thus, our method online adapts the variations occurring in real-time hand movement and exhibits high efficiency in cognitive recognition of hand trajectory. The empirical results shown in the chapter demonstrate that the approach can withstand the intrinsic as well as extrinsic challenges associated with visual tracking of hand gestures in RGB videos.
Abiotic and Biotic Factors: Effecting the Growth of Keratinophilic Fungi
Authors: Mathur Manish , Mathur Neha
Published: April 2022

Fungi portray an important role in decomposition of keratin, as their activity is tough to measure. According to an estimation, a quantity of cellulose is synthesized by primary producers over photosynthesis and then reinstated to the atmosphere as carbon dioxide and through the activity of fungi, which decompose the complex and inflexible polymer. Without this activity, the world would soon be submerged by plant residues, and this would probably exclude most living organisms from their natural habitat. This chapter deals with several abiotic and biotic factors, which effect the growth of keratinophilic fungus and the substrates, which can serve as potential growth promoters for them.
Sediment Transport in River Flows: New Approaches and Formulas
Authors: Shmakova Marina
Published: April 2022

A new method for estimating the total sediment discharge, as built on balance of power acting to moving sediment particle in “water stream-bottom sediments—sediments” system, enables consideration of interrelated influence of hydraulic variables state of flow and sediment. At the same time, the basic sticking point of river hydraulics, that is, interaction of fluid and bottom, is specified not from the part of fluid boundary, but from that of bottom sediments and their properties, well studied in soil science. Setting the size of bottom sediments by means of their qualitative characteristics allows avoiding calculation errors that occur when using specific values of quantiles of bottom sediments in calculations. Consideration of the critical velocities and the phase hydraulic space of the flow allowed obtaining the equations for transporting capacity of the flow, suspended, and bed load discharges.
Electronic Structure of Chlorophyll Monomers and Oligomers
Authors: Matti Linnanto Juha
Published: April 2022

This chapter deals with the electronic structure of chlorophyll molecules and their complexes. Different theoretical and quantum chemical calculation methods are used to study the molecular and electronic structure of chlorophylls. Studied spectral region covers ultraviolet and infrared spectral regions, containing blue side of the Soret band, as also traditional Qy band region. Thus, there are not only focusing on the traditional Qy, Qx, and Soret transitions of chlorophylls but also high-energy transitions (in this region also proteins and nuclei acids absorb light). The aim is to show the effect of molecular conformation on the electronic states and thus on the absorption and emission spectra of monomers and oligomers. In chlorophyll-protein complexes, such conformation effect finetuning the spectral transitions and increases overlap between donor and acceptor states of energy transfer processes. Also, the role of vibronic transition in the shape of absorption and emission spectra of the studied systems will be considered.

Published: April 2022

Occurrence of fungi from the genus Fusarium depends on the effects of various climatic factors, and the production of fumonisin depends on weather conditions and the location of plantation. Climate data show changes in temperature and precipitation and may provide insight into their impact on fungal development and fumonisin production (FB1 and FB2). LC-MS/MS method for FB1 and FB2 determination was developed. Linearity of the method was in the range 10-400 ng/mL for FB1 and 3-120 ng/mL for FB2 with correlation coefficients R2 > 0.99. Limits of quantification were 25 mg/kg for FB1 and 7.5 mg/kg for FB2. Recovery was in the range from 87 to 96.7%, with method precision lower than 16%. The method was applied for analysis 36 samples, and in 19 were detected fumonisines FB1 and FB2 in concentrations over the limit of quantification. In three samples concentrations of FB1 and FB2 were over MRL set by EC/1881/2006 (sum FB1 and FB2 2000 mg/ kg), but lower than MRL set by our National regulation (4000 mg/kg).

Published: April 2022

In this study, the petals collected from peony hybrid Paeonia lactiflora "Bowl of Beauty" and Calendula officinalis L. were extracted using an ethanol-water mixture assisted with microwave and ultrasonic treatment. The isolation of Calendula officinalis L. essential oil was done by hydrodistillation as well. The total phenolic and flavonoids content in the extracts and oil were determined and their antioxidant activity was evaluated. The highest total phenolic content was found for the extracts of hybrid Paeonia lactiflora and Calendula officinalis L. obtained by ultrasound extraction (83.16 and 114.47 mg GA/g, respectively), while the flavonoid content obtained by microwave-assisted extraction was relatively high (123.48 and 65.29 mg QE/g, respectively). The highest antioxidant activity was obtained in DPPH • and ABTS •+ assay for the microwave-assisted extraction of hybrid P. lactiflora (79% and 83%) and ultrasound-assisted extraction of C. officinalis L. (45% and 49%), respectively. To improve antioxidant activity of both types of examined analytes (extracts and essential oil), the pectin biopolymer film (as a carrier) was prepared in the process of enzymatically assisted catalysis. Optical microscopy and FTIR spectroscopy were used for the characterization of obtained materials. The films, with essential oil of C. officinalis L. and gallic acid, showed significantly increased percentage inhibition in DPPH • and ABTS •+ test (91% and 95%, respectively) after 10 minutes. The results, also, showed that all formulations of pectin biopolymer film, modified with gallic acid, can be successfully applied as a carrier for both types of ingredients.
Open surgical treatment of abdominal aortic aneurysms in the endovascular era
Authors: Davidović Lazar
Published: April 2022

In addition to the well-known benefits, endovascular treatment (EVAR) of abdominal aortic aneurysms has its drawbacks and limitations. That is why open surgery (OS) still has a very important place. OS should be considered as the first treatment option for degenerative AAAs with either favorable or unfavorable anatomy in low-risk patients with long life expectancy. When it comes to inflammatory AAA, OS is indicated only in patients at low risk and hydronephrosis. OS is the "gold standard" for the definitive treatment of mycotic AAAs. In cases of complete thrombosis AAA is the only viable OS. OS is the method of choice in AAA with associated significant accessory renal arteries. OS is the method of choice for the treatment of AAA in patients with connective tissue disorders. Different types of endolic, infection, collapse and stent graft migration, or aneurysmal sac rupture, require late open surgical conversion after EVAR. OS is indicated if patients with RAAA are severely hemodynamically unstable, if they do not have a favorable anatomy, or if they have a large retroperitoneal hematoma. OS AAA can be performed only in centers with a large volume of work by experienced surgeons. The younger generation of vascular surgeons must be educated for both EVAR and OH AAA.

Published: April 2022

Introduction: Over the past 15 years, direct oral anticoagulant (DOAC) drugs have replaced vitamin K antagonists in a number of indications requiring oral anticoagulant therapy. Review work: The article written is an overview of the most important information related to the use of DOAC drugs in the secondary prevention of venous thromboembolism (VTE). The first randomized studies with dabigatran, rivaroxaban and apixaban are presented, which introduced these drugs into clinical practice in the first step, and then enabled the prolonged safe use of these drugs in the secondary prevention of VTE. Studies have also been described as current attitudes for the use of DOAC in patients with VTE associated with malignancy and antiphospholipid syndrome. An assessment of the risk of bleeding in patients with DOAC is also presented. Finally, we briefly presented the results of the use of DOAC in the treatment of pulmonary embolism in a group of patients from the regional PE registry.
Spironolacton in the therapy of resistant hypertension
Authors: Milošević Maja , Otašević Petar
Published: April 2022

Hypertension is the most common chronic non-communicable disease, and it is estimated that about 7 million deaths a year are associated with poor regulation of blood pressure. In addition, these patients have a higher incidence of disability as well as increased treatment costs. One of the most important causes of poor blood pressure regulation is resistant hypertension. Due to all the above, in the last decade, there has been an increase in researchers' interest in studying the pathogenesis, diagnosis and treatment of resistant hypertension. However, the latest data indicate that 20% of women and 24% of men with arterial hypertension still have poor regulation of blood pressure, despite the use of maximum doses of three antihypertensive drugs (including diuretics) and an appropriate lifestyle. In these patients, the recommendations advise the introduction of mineralocorticoid receptor antagonists as a fourth-line drug, and in case of unsatisfactory therapeutic effect, consideration of new treatment modalities (renal catheter denervation and baroreceptor stimulation). In this article, we summarize the current knowledge on different pathogenetic mechanisms and adequate diagnostic approaches in patients with resistant hypertension. We also gave an overview of current therapeutic approaches, with special reference to spironolactone.
Acute rhinosinusitis: Pathogenesis, diagnosis and treatment
Authors: Perić Aleksandar
Published: April 2022

Acute rhinosinusitis (ARS) is an inflammation of the mucous membranes of the nasal cavity and paranasal sinuses with symptoms lasting up to 12 weeks. In more than 98% cases, ARS begins as a viral infection with common cold symptoms, usually caused by rhinoviruses or more severe acute viral rhinosinusitis usually caused by coronaviruses, influenza and parainfluenza virus. Worsening of symptoms after 5 days or persistence of symptoms after 10 days indicate the diagnosis of acute postviral rhinosinusitis, which indicates the presence of bacterial superinfection on the basis of previous viral infection. In about 0,5-2% of cases, complications of ARS with bacterial infection occur, so we have a clinical history of acute bacterial rhinosinusitis (ABRS). The most common causes of ABRS are Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. Diagnosis and treatment of uncomplicated ARS are the responsibility of primary care physicians. Failure in treatment indicates a potential complication of the disease, when the patient needs to be referred by an otorhinolaryngology specialist. The first line of the antimicrobial treatment of ARS is the use of amoxicillin. Inadequate response to firstline antimicrobial therapy within the 72 hours indicates the need for some broad-spectrum antibiotics. Complementary therapy consists of the use of saline solutions for rinsing the nasal cavity, decongestants in the form of drops, sprays or tablets, herbal drugs, as well as intranasal corticosteroids in the form of sprays.
Topical preparations in the treatment of musculoskeletal pain
Authors: Tomašević-Todorović Snežana
Published: April 2022

Musculoskeletal pain is a global health and socioeconomic problem. Chronic musculoskeletal pain (MSC) is a pain that lasts for at least 3 months, becomes a disease itself. Given the constant increase in the frequency of musculoskeletal pain, it is necessary to work on improving prevention, early diagnosis and therapy, in order to improve outcomes and reduce treatment costs. Causes of MSC pain can be degenerative and / or inflammatory changes of joint and extra-articular structures, as well as dynamic vertebral segment. The use of symptomatic therapy for pain and swelling must be based on adequate patient selection, selection of the painful condition, with a balance between the risks of use and benefits. The stepwise approach of the WHO (World Health Organization) analgesic ladder represents an escalation strategy from weak to strong analgesics in pain therapy. Nonsteroidal anti-inflammatory drugs are used in the treatment of mild to moderate acute and chronic musculoskeletal pain with an inflammatory component. The choice of nonsteroidal anti-inflammatory drugs in the treatment of pain is useful as monotherapy and as a component of multimodal analgesic therapy. The average prescribed daily dose, as well as the length of drug use in the treatment of musculoskeletal pain must be in accordance with the guidelines. Topical application of NSAID-s is the therapy of choice within the pharmacological approach in elderly patients, with acute and chronic musculoskeletal pain in accordance with modern guidelines.
Exploring direct and non-linear effects of entrepreneurial orientation and its dimensions on firm performance in a small, open, transitional economy
Authors: Morić-Milovanović Bojan
Published: April 2022

Background: The relationship between entrepreneurial orientation (EO) and small firm performance has been extensively researched over the last couple of decades. However, the scientific community still does not have a unanimous view regarding non-linear relationships between EO and performance, especially when adding separate EO dimensions. Purpose: This paper explores the non-linear relationship between EO, observed as a unidimensional and multidimensional construct, and small business performance within a small, open, and transitional economy. Moderation effects of environmental turbulence on both direct and non-linear EO-performance relationships have been explored, as well. Study design/methodology/approach: Hierarchical regression analysis was used to test the research hypothesis on the data collected from 109 Montenegrin SMEs. Finding/conclusions: Results reveal that EO has a direct and inverted U-shaped non-linear relationship with small firm performance. Innovativeness and proactiveness have a direct positive effect on small firm performance. Risk-taking and autonomy have an inverted U-shaped non-linear relationship with small firm performance. Environmental turbulence does not positively moderate direct nor non-linear relationship between EO and small firm performance. Limitations/future research: Limitations refer to the relatively small dataset which may affect the strength of the result. Specific national institutional and cultural setting could also influence the findings. Information was gathered from the owners and managers of the observed firms which limited the ability to gather more diverse information from other stakeholders. Research focused on only one moderator explaining the non-linear relationship between EO and small firm performance. Therefore, future research should focus on conducting a multi-country analysis with larger data sets to strengthen the external validity of the present study, and should adopt a multi-level perspective in investigating the role of inter-relations among EO dimensions in explaining performance variations. Future studies should continue testing the effects of other moderators in explaining the non-linear relationship between EO and firm performance, especially within a longitudinal context.

Authors: Araya Seguel Claudio
Published: April 2022

Este artículo ofrece una posibilidad de sinergia teórico-metodológica para el abordaje de distintos problemas sociales. Se trata de un trabajo que explora la participación de la comunidad gay en el mundo social configurado en textos de ciberprensa chilena entre los años 2012-2017. La exploración se realiza desde la articulación teórico-metodológica de los sistemas sociosemióticos de VALORACIÓN e IDEACIÓN adscritos a la Lingüística sistémico funcional para ilustrar la relación entre el cambio social y el cambio discursivo. El análisis discursivo desde esos sistemas revela que la comunidad gay representada en el corpus se constituye en agente de transformación social, pues denuncia la violencia homofóbica y defiende a las víctimas, interpela a las autoridades políticas y religiosas, promueve cambios y reformas legales y es reconocida como interlocutor político ante los eventos producidos.
This article offers a possibility of theoretical-methodological synergy for addressing different social problems. This is a work that explores the participation of the gay community in the social world configured in Chilean cyberpress texts between 2012-2017. The exploration is carried out from the theoretical-methodological articulation of the sociosemiotic APPRAISAL and IDEATION systems assigned to functional systemic linguistics to illustrate the relationship between social change and discursive change. The discursive analysis from these systems reveals that the gay community represented in the corpus constitutes an agent of social transformation, because it denounces homophobic violence and defends the victims, questions political and religious authorities, promotes changes and legal reforms and is recognized as political interlocutor before the events produced.
Izzivi sodobne slovenske pediatrične paliativne oskrbe
Authors: Meglič Anamarija
Published: April 2022

Paliativna oskrba otrok je specializirana paliativna oskrba z določenimi posebnostmi v primerjavi s paliativno oskrbo odraslih. Enačenje načel sodobne paliativne oskrbe otroka s protokoli opustitve in odtegnitve zdravljenja je odraz nepoučenosti in je povsem napačno. Multidisciplinarni tim za paliativno oskrbo otrok na terciarni ravni sestavljajo otrokovi lečeči subspecialisti, medicinske sestre, psiholog in po potrebi drugi zdravstveni sodelavci, med njimi tudi tisti z dodatnim znanjem iz paliativne medicine in zdravstvene nege. Tim oblikuje načrt nadaljnjega zdravljenja ter postopke oskrbe nenehno prilagaja rasti in razvoju otroka, napredovanju bolezni, slabšanju bolnikovega stanja in pojavljanju novih težav. Vsebina načrta paliativne oskrbe je odvisna od trenutka vključitve bolnika in njegove družine, vrste bolezni ter prepoznanih in izraženih potreb. V pediatriji se potreba po uvedbi paliativnega pristopa pri zdravstvenih delavcih pogosto prepozna prepozno ali pa se sploh ne. S širjenjem znanja in zavedanja koristi sodobne pediatrične paliativne oskrbe za bolnike in njihove svojce poskušamo doseči, da postane paliativni pristop pri bolnih otrocih z neozdravljivo napredujočo boleznijo del vsakodnevne klinične prakse. Ne gre le za eno neodtujljivih pravic najtežje bolnih otrok, gre tudi za delo zdravstvenih delavcev v skladu z etičnim kodeksom, da zdravljenje, ki je bolniku bolj v breme kot v korist, etično ni utemeljeno.

Published: April 2022

The number of CubeSats launched to space has largely increased during last years. Any kind of satellite, even CubeSats, need to have some control on their attitude for pointing, i.e. antenna to Earth or solar panels to Sun. Among the available technology to control the attitude, CubeSats usually have cylindrical coils called magnetorquers, whose magnetic field interacts with the Earth’s magnetic field. CubeSat To verify its performance, it can be used a testing facility capable of simulating magnetic field along the satellite orbit. This work presents a metrological uncertainty analysis of a testing facility based on Helmholtz cage. Magnetic field uncertainty is obtained by performing uniformity, stability and gaussmeter calibration error tests. To simulate low Earth orbit satellite magnetic field conditions, the International Geomagnetic Reference Field model is used. The operation algorithms and software, developed using Python language, are validated by contrasting its results with Systems Tool Kit software, a commercial package, showing a maximum relative error of 0.03 %. Values from the testing facility are compared with in-situ measurements from Lume-1 satellite on-board gaussmeter, showing a maximum discordance lower than 50 mG.

Published: April 2022

Today's huge automotive industry requires continuous innovations. In this sense, numerous publications on new materials or developments which can provide new weight reductions or safety improvements are released every day. An important example is hot stamping, which has been gaining popularity in the last years due to its advantages for the sector. Considering the strong influence of the automotive sector in world economies, we have focused our attention on the literature concerning not only hot stamping itself but also on several other technologies which are related to the same transformation procedure, to have a complete photograph of the evolution of the technology itself. We contribute with a systematic literature review process, enriched by a bibliometric review. The use of both contributes in a neutral, reliable manner, reducing the possible bias of traditional literature reviews, which have been previously employed in this specific discipline. We have resorted to the Web of Science to execute a query related to all the possible procedures that involve hot stamping technology, which correspond with 573 English peer reviewed publications from journals indexed in this database. The results clarify that hot stamping is a key issue in metallurgy publications with significant future prospects due to its manufacturing implications.

“Putting on Her White Hair”
Authors: Barnes Lipscomb Valerie
Published: April 2022

Thornton Wilder’s The Long Christmas Dinner (1931) holds a unique place in American drama, as it covers ninety years in the history of one family. The one-act play captivated composer Paul Hindemith, who collaborated with Wilder to adapt The Long Christmas Dinner as a 1961 short opera by the same name. Analyses of both works overlook the representation of age and aging on stage. Actors perform the aging of characters from young adulthood to death in just a few minutes of stage time, challenging the “difference” of age by suggesting the stability of human identity over the life course. One element of ageism is the perception that changes of age entail changes in identity. In Wilder’s play, although the actors use props that stereotype the changes of age, such as a white wig or wheelchair, no major transformation of identity is evident. The play is short enough that the audience never forgets that one actor embodies a character from young adulthood through death. Thus, the onstage life course becomes a natural continuum marked by mile- stones of experience, rather than an Othering of the aged. Each character who grows old remains central to the family until death. As age studies activists and scholars look to the arts for reflections of social age construc- tion and for potential models of age equality, they may find useful this artistic vision of age as performative.

“Polyester Pants and Orthopedic Shoes”
Authors: Gentry Lamb Erin
Published: April 2022

This article describes several in-class exercises that can be used to introduce basic age studies concepts to students within one class setting. These exer- cises, built around the Age Assumptions Survey and grounded in age studies theory, are designed for use with traditional (late-adolescent) undergraduates but could be used with other populations and across disciplinary settings, such as graduate or professional students in fields ranging from the human- ities to the social sciences to the healthcare professions. These engagement exercises are intended to (1) introduce age as an identity category that is vari- ably defined and, at least in part, socially constructed; (2) reveal students’ basic assumptions and stereotypes about aging and old age; and (3) pro- vide a limited introduction to ageism. The exercises are designed so that the students generate both content and analysis, structurally forcing students to confront the limitations and ageism in their own assumptions about aging and old age. The self-generated nature of the critique encourages students to accept their own biases rather than profess their impartiality.

Clothing, Embodied Identity, and Dementia
Authors: Buse Christina , Twigg Julia
Published: April 2022

Clothes are central to how we perform our identities. In this article, we show how these processes continue to operate in the lives of people with dementia, exploring the ways in which dress offers a means of maintaining continuity of self at a material, embodied level. The article thus contributes to the wider cultural turn in aging studies, showing how material objects are signifcant in meaning-making, even for this mentally frail group. The article draws on the Economic and Social Research Council (ESRC)-funded study “Dementia and Dress,” which examined the implications of clothing for people with dementia, carers, and care workers, using ethnographic and qualitative methods. It showed, despite assumptions to the contrary, that dress remained signifcant for people with dementia, continuing to underwrite identity at both the individual level of a personal aesthetic and the social level of structural categories, such as class, gender, and generation. The article explores how identity is performed through dress in social interaction, and the tensions that can arise between narrative and embodied enactment and around the “curation” of identity. Dress provides a lens for understanding the lives of people with dementia, while at the same time, focusing on dementia expands discussions of fashion, consumption, and cultural meanings of aging.

Putting Age into Place
Authors: Kriebernegg Ulla
Published: April 2022

This paper addresses cultural constructions of old age in two contemporary Canadian care home narratives. While John Mighton’s play Half Life (2005) is set in a prison-like long-term care facility that is represented as a site of homogenization, oppression, and infantilization, Joan Barfoot’s novel Exit Lines (2008) plays in a hotel-like retirement lodge for wealthy customers that, despite its authoritarian manager, functions as a site of meaningful identity development and intragenerational relationships. What both texts have in common, however, is that they focus on residents’ individual resistance, subversion, and agency, thus opposing the ageist stereotype of decline and deconstructing prevailing norms and negative images of old age as merely physical decrepitude and disease. How is the space of the care home narrated in these two contemporary Canadian texts, and what role do aspects of space and place play for the narrative construction of old age? In this paper, I argue that the spatiality of aging is a category that needs to be incorporated into both an analysis of literary representations of the “fourth age” and an exploration of critical issues of space and place. The juxtaposition of two caregiving institutions in recent Canadian fction contributes to revealing how old age is imagined at the beginning of the twenty-frst century.
How to Recognize an Adult When You Meet One?
Authors: Van Lierop-Debrauwer Helma
Published: April 2022

Children learn about the cultural meanings of age and aging from the people in their environment but also from the media. In an era in which the different life stages are understood as a continuum rather than separate categories, age socialization has probably become more complicated than ever before, making the role of the mediators—children’s books and flms included—especially important. This article explores the mediation of aging in Minoes (1970), a children’s book by Annie M. G. Schmidt—the most famous Dutch author of children’s books—and compares its age ideology to that of the flm adaptation, which appeared in 2001. The comparison is set against the background of changes over the last ffty years in how aging is perceived within Western societies. Both in the book and in the flm, this analysis shows, the model of standard adulthood is under revision. Instead of representing a fxed age identity, adulthood is portrayed as being as much a process of becoming as childhood is, as it is characterized by inner growth and making individual choices. Although the similarities between book and flm are more striking than the differences, the flm’s adult protagonists are slightly more capable of making their own decisions than those in the book; this difference mirrors the ongoing shift towards a changing perception of adultness that had only just started when the book was published in 1970.
