Authors:   Satbayev University, Sarzhanov N. , Abdrakhman A. ,   Satbayev University
Published: June 2023

Mass urban development in Kazakhstan has been the subject of discussions and scientific research for many years. Unsatisfactory housing conditions, unhealthy urban environment require specific proposals for housing renovation. This study reveals the specifics of mass housing in Kazakhstan and determines the feasibility of residential buildings’ renovation. Despite the fact that specialists from the economic, social and architectural fields of sciences have studied the topic, there is still ambiguity in solving the following issues: renovation strategy in the country; the possibility of residential buildings' renovation; types of residential buildings to be renovated. As a result of a comparative analysis of design materials, literary sources and statistical data, the authors determined the classification of multi-apartment residential buildings of mass series in the Republic of Kazakhstan. This classification combines the chronological order of construction, the type of structural scheme of buildings and the name of the series of residential buildings. The systematization of statistical data of the housing stock by various parameters made it possible to identify, with a small error, the proportion of multi-apartment housing subject to renovation. In addition, this work generally reveals the problem of renovation in the country related to the structure of the housing stock, the peculiarity of housing and communal services and the process of architectural and urban planning design.
Equine Misbehavior and Its Relationship to Temperament and Rider Induced Stress
Authors:   ,   Andrews University, Huffman Taylor
Published: June 2023

The goal of this study was to determine if there was a relationship between horse temperament and incidence of misbehavior due to the stress of being ridden by riders with a wide range of ability during the course of a summer camp session (9 weeks). It was hypothesized that horses with a social or aloof temperament would be able to adjust with more ease, while those with a fearful or challenging temperament would have a higher incidence of misbehavior. Each horse was evaluated for temperament at the beginning of the summer camp season. In the following weeks every rider was evaluated for rider skill level; their skill level, their lengths of trail rides, and incidences of horse misbehavior on those rides were all recorded. The rider skill level was multiplied by the length of the ride in minutes to develop a stress index. A significant relationship (p <.0001) between equine stress levels and the level of misbehavior was shown to vary by temperament with lower incidence of undesirable behavior exhibited by the social and aloof horses.

Published: June 2023

The goal of my research is to help the Andrews University School of Business Administration (SBA) improve student satisfaction by identifying which factors are most closely correlated with undergraduate students' satisfaction and perceived quality. I studied satisfaction as a dependent variable measured in relation to nine different double-headed service factors (measured for satisfaction level and degree of importance) provided by the SBA: 1. Curriculum, instruction, and classes, 2. Teaching in subject matter, 3. Advising, 4. Quality of teaching and feedback, 5. Computing resources, 6. Social and extra-curricular components, 7. Preparation for career or graduate school, 8. Physical and office properties and 9. Religious components. To measure student satisfaction I utilized a survey tool I created based on the Student Satisfaction InventoryTM, the Undergraduate Business Exit Assessment, and the AU Senior Survey and Course Survey. Results were evaluated with SPSS analytical software to perform step-wise regression analysis and R statistical software to perform multiple analysis of variance (MANOVA). This unique survey tool revealed six factors that were most closely correlated with overall student satisfaction: 6B. Satisfaction with social and extra-curricular components, 7B. Satisfaction with preparation for career or graduate school, 2B. Satisfaction with teaching in subject matter, 7A. Importance of preparation for career or graduate school, 2A. Importance of teaching in subject matter and 8B. Satisfaction with physical and office properties. The research revealed areas important to improving the Andrews University undergraduate business experience.
Discourse and Narrative: Creating Gender Control in Junot Diaz's the Brief Wondrous Life of Oscar Wao
Authors:   ,   Andrews University, Lee Charles
Published: June 2023

Junot Diaz's Pulitzer-Prize-Winning 2007 novel The Brief Wondrous Life of Oscar Wao explores Dominican masculinity through narrator Yunior de Las Casas's portrayal of protagonist Oscar de Leon's family history. Yunior's perceived virility shapes his understanding of masculinity, which he stresses through the novel's plot and structure. This analysis considers how Yunior constructs Dominican masculinity through his narrative by marginalizing and emasculating passive character such as Oscar. I argue that Yunior's narrative closely links definition of masculinity and power as he strives to dominate passive characters in order to assert his virility as the "best" method for being a Dominican man.

Analysis indicated a significant association between substance use problems of fathers and their children's substance use. There was a stronger statistical association between father's substance use problems and male children's alcohol use. In addition there was a significant relationship between grandparents substance use and youth sexual behavior for both genders. There is a need for further analysis of this study.
Ovulation Synchrony as an Adaptive Response to Egg Cannibalism in a Seabird Colony
Authors:   ,   Andrews University, Weir Sumiko
Published: June 2023

The predominant cause of egg loss in a large Galucous-winged Gull (Larus glaucescens) colony in Washington is cannibalism. Previous work demonstrated the occurrence of every-other-day clutch initiation synchrony in dense areas of the colony during years when cannibalism was most frequent, suggesting that synchrony is an adaptive response to cannibalism. Here we show that (1) the initial egg laid in a nest is more likely to be cannibalized than subsequent eggs, (2) an egg is most likely to be cannibalized within the first 24 hours after it is laid, and (3) the odds that an initial egg is cannibalized within the first 24 hours decreases with an increase in the total number of initial eggs laid on that day. These findings support the hypothesis that clutch initiation synchrony functions as an adaptive response to cannibalism by increasing the odds that an initial egg will survive during its most vulnerable period.
Anticancer Activity of Some Boronic Acid Arylidene Heterocycles
Authors:   ,   Andrews University, Kim Joy
Published: June 2023

This research was done in order to investigate the anticancer activity of boronic acid arylidene heterocycles. Boronic acid, heterocycles, and aryl compounds have all independently exhibited various anti-microbial properties and have shown potential to be used in pharmaceuticals for the treatment of viruses and cancers. Using a one-step protocol developed by Dr. Murray, several different arylheterocyclic compounds were combined with an arylboronic acid to synthesize novel compounds. These were then tested for their anti-cancer activity on glioblastoma brain cancer cells. Although varied in potency, all had some amount of anti-cellular effect on the cancer cells. This is only the start of analyzing these compounds and further research should be done in order to realize their full potential.
L3 Auditory Interneuron Responses to Dual-frequency Calling Songs in Female Crickets (Acheta Domesticus)
Authors:   ,   Andrews University, Lee Jeong Bin
Published: June 2023

Female crickets exhibit positive phonotaxis in response to calling songs with specific carrier frequencies (4-5 kHz), syllable periods (SP; 50-70ms), and other parameters. Among a number of ascending prothoracic auditory neurons identified, only L3 has been proposed to be involved in SP selective phonotaxis. L3 responds with selective decrement to 5 kHz stimulus with attractive SPs. Furthermore, L3 is highly tuned to 16 kHz auditory stimulus, which has been correlated with aversive phonotactic behaviors. L3’s cellular responses to simultaneous 16 kHz and 5 kHz stimuli were examined through extracellular recording, thereby further establishing the connection between L3’s selective decrement and selective phonotatic behavior.
The Chronology of the Events in Zechariah 12-14
Authors:   ,   Andrews University, Jeon Won Jin
Published: June 2023

In current scholarship, there is a lack of consensus on the timing of the specific events in Zechariah 12-14, with a focus on eschatological or sequential chronologies. Preliminary exegetical research has revealed many connections between the three chapters. For instance, the phrase “in that day” ( ביום־ההוא ) occurs 17 times (versus four times in the rest of Zechariah). This concentrated usage closely interconnects the three chapters and suggests that the timeliness of all of the events is in close succession. Through findings in literary structures, key words, and intertextualities with other passages of the Old Testament, the conclusion is that the events in Zechariah 12 and 13 occur in one day. Even more, there exist literary structures and patterns that seem to support the idea that the various “in that day” events in Zechariah 14 occur in a single time, which is later than the day in Zechariah 12-13.

The Effects of Omega-3 Fatty Acids on Intracellular Inositol Levels in Saccharomyces Cerevisiae
Authors:   ,   Andrews University, Lee Joanne
Published: June 2023

Bipolar disorder is a severe and chronic debilitating mental disorder characterized by extreme mood swings between mania and depression. The current medications for bipolar disorder, lithium and valproate, have been associated with numerous negative side effects. Although the therapeutic mechanism by which lithium and valproate (VPA) exert their effect is unknown, a leading hypothesis implicates inositol depletion as a mechanism of action. On the other hand, omega-3-fatty acids have been shown to relieve symptoms of bipolar disorder. In this study, we compare the effects of VPA to the effects of decosahexaenoic acid (DHA) on Saccharomyces cerevisiae growth and intracellular inositol concentration. Intracellular inositol levels were examined using a modified enzymatic assay for inositol, which correlates light absorbance to intracellular inositol concentration. The results show that similar to valproate, DHA inhibits cell growth. In addition, unlike valproate, DHA does not decrease intracellular inositol levels.
Synthesis, Isolation, and Characterization of Potentially Carcinogenic Arginine-Based Heterocyclic Amines
Authors:   ,   Andrews University, Reichert Zachary
Published: June 2023

Previous research demonstrates that meat cooked at high temperatures produces heterocyclic amines (HCAs)—a class of carcinogenic molecules—from burned creatin(in)e and amino acids. However, research performed in our lab, as well as in the peer-reviewed literature, suggests that substituting arginine for creatin(in)e may lead to HCA formation. Arginine is structurally similar to creatin(in)e and can be found abundantly in soy-based food products. Therefore, we have burned arginine and phenylalanine to investigate the potential formation of arginine-based HCAs. The present study attempts to isolate and characterize these potential arginine-HCAs.
Exposure to Video Media and its Effects on Attitudes Towards Law Enforcement
Authors:   ,   Andrews University, Gonzalez Amante
Published: June 2023

This study examined how exposure to video media (specifically media geared toward a social media platform) depicting either negative or positive police interactions with individuals will influence perception of law enforcement officials. Using a modified version of the Building a Relationship of Trust Community Perception Survey (BRTCPS) subjects (N=43) responses were analyzed using a two way ANOVA. Results indicated a strong main effect for exposure to both the negative and positive police interaction videos in regards to attitudes towards law enforcement. These findings support the thesis that the videos emotional valence is extremely successful in altering individual’s attitudes towards law enforcement in the intended direction.
Graphene Kirigami And Its Use In Biocompatible Strain Sensor
Authors:   ,   Andrews University, Vyhmeister Erik
Published: June 2023

Graphene's large fracture strain (>30%), chemical inertness, and piezoresistive nature make it well suited for use as a biocompatible strain sensor. A rectangular multilayer strucutre with graphene as its operative component was designed. It consists of a bottom layer of SU-8, a center layer of graphene, and a top layer of SU-8 and gold, with gold acting as the electrical contact. Kirigami-style patterning is applied via photolithography and oxygen plasma etching, allowing for a greater fracture strain. Additionally, the kirigami affects the stress concentraton in the graphene, affecting its piezoresistive gauge factor. The complete (patterned) structure exhibited a fracture strain of 40%, a 900% increase over unpatterned SU-8 of similar thickness.
Fault Tolerant Hash Join for Distributed Systems
Authors:   Saint Petersburg State University, 28 Universitetskiy pr., Stary Peterhof, 198504, Saint Petersburg, Russia, Nasibullin Arsen
Published: June 2023

Nowadays, enterprises are inclined to deploy data processing and analytical applications from well-equipped mainframes with highly available hardware components to commodity computers. Commodity machines are less reliable than expensive mainframes. Applications deployed on commodity clusters have to deal with failures that occur frequently. Mostly, these applications perform complex client queries with aggregation and join operations. The longer a query executes, the more it suffers from failures. It causes the entire work has to be re-executed. This paper presents a fault tolerant hash join (FTHJ) algorithm for distributed systems implemented in Apache Ignite. The FTHJ achieves fault tolerance by using a data replication mechanism, materializing intermediate computations. To evaluate FTHJ, we implemented the baseline, unreliable hash join algorithm. Experimental results show that FTHJ takes at least 30% less time to recover and complete join operation when a failure occurs during the execution. This paper describes how we reached a compromise between executing recovery tasks for the least amount of time and using additional resources.

The article analyzes the changes in the teaching of mathematics at school associated with the development of the digital educational environment. The theoretical analysis is accompanied by a discussion of basic examples of changes in the main content course lines, such as the algebraic line, the function-theoretic line, the line of equations and inequalities, the geometric line, the stochastic line, the line of discrete mathematics and theoretical computer science. In the process of constructive analysis, such types of changes are considered as: a shift in emphasis from operational activities to modeling, which is associated with the development of “computational thinking” (computational thinking); the use of digital representations of mathematical concepts for the formation of mental images of mathematical concepts and increasing attention to the operation of mental images; studying the material at various levels of complexity through the use of computer models; study of algorithms that are used in computer mathematics systems; the development of horizontal connections both in the methodological aspect through the increasing role of integrative plots that combine various sections of mathematics and computer science, and in the aspect of general pedagogy through the construction of common information spaces for the interaction of educational communities and the expansion of their participants.
Comparative Analysis for Survival Period of SMEs According to Innovation Certification Type
Authors:   The Korean Production And Operations Management Society, Lee Jun-won
Published: June 2023

In terms of survival period, it was analyzed whether there was a significant difference according to the type of innovation certification (venture certification, inno-biz certification and main-biz certification). The event was defined as overdue equivalent to default, and the survival period was calculated. Based on the year of innovation certification, the work experience, number of employees, financial status, and composition by industry of innovation certified SMEs were set as control variables. As a result of the analysis, it was confirmed that there was a significant difference in the survival period depending on the type of innovation certification even when the control variables were considered. Inno-biz certified companies and main-biz certified companies had a 31.2% and 29.3% reduction in overdue risk, respectively, compared to venture certified companies. Therefore, it is necessary to differentiate innovation certification benefits by considering the life cycle of a company. In addition, it was concluded that there is a need to strengthen the connection between certifications, such as providing additional benefits when converting innovation certification.

During the coronavirus disease 2019 (COVID-19) pandemic, remote retail emerged as a feasible option for safe shopping. A significant increase in online and mobile sales has been reported based on secondary data, but few studies have focused on the psychological and cognitive factors that systematically affect consumers’ behavioral intention of shopping online. This study explores specifically the effects of the perceived severity of and vulnerability to COVID-19 on consumers’ intention to use online or mobile shopping. We also included consumers’ propensity for self-isolation as a mediator and subjective norm as a control factor for their intention to shop remotely. The data were collected through an online consumer survey and analyzed using structural equation modeling. The results indicate that perceived severity significantly affects propensity for self-isolation but does not directly affect online shopping intention. Additionally, the effect of perceived severity on intention to shop online is mediated by propensity for self-isolation. In contrast, perceived vulnerability negatively affects propensity for self-isolation and remote shopping intention, implying that not all the consumers are willing to shop online even under the threat of COVID-19.
Paper bending stiffness and web tension measurement from a running web using a vacuum and computer imaging
Authors: SALO MIKKO , ERKKILÄ ANNA-LEENA , VILKKO MATTI , KANERVA MIKKO
Published: June 2023

A novel method for measuring the bending stiffness of paper online during manufacturing is intro-duced. The method uses photometric stereo imaging to detect the shape of the deflection surface caused by a controllable pressure difference over the paper’s surfaces. The hardware for the measurement is based on a combination of two existing sensors, which has accelerated and facilitated the development of the implementation. The deflection and loads are tied together by the governing differential equation for the bending of an orthotropic elastic plate with selected simplifications. An approach to resolve material parameters and in-plane loads without knowledge of traditional boundary conditions is suggested. The presented method was tested in a paper mill during manufacturing. For bending stiffnesses measured online, correlation coefficients 0.88 and 0.92 were obtained compared to state-of-the-art laboratory measurements. However, the results gained from a moving web are noisy and the data requires correction of the slope and an offset. Although several issues remain to be resolved before the method can be considered as an accurate measurement for industrial use, the theoretical background, the performance of online implementation, and the results are promising. Possible causes for the observed discrepancies and the future development of the method are discussed.

Published: June 2023

Introducción: En la actualidad hay un incremento de los delitos sexuales en el país, y muchos quedan en la impunidad porque no han sido reportados o lo hacen de manera tardía, ya que las víctimas tienen temor a denunciar el hecho para no ser revictimizadas durante el proceso legal. El trabajo pericial en biología forense inicia con la toma de muestra de la víctima y el análisis de muestras biológicas, se centra en la investigación de semen o líquido espermático, que se pudieran haber dejado tanto en la víctima como en el lugar del hecho, y se continua con la búsqueda microscópica para visualizar espermatozoides utilizando la tinción específica "Christmas Tree o árbol de navidad". Metodología: El propósito de la investigación fue validar las tinciones Diff Quick, Gram, Panóptico y Papanicolau como técnicas alternativas para la identificación de espermatozoides y su posible aplicación en la investigación forense. El diseño fue experimental ya que se manipulan intencionalmente los parámetros de prueba y compara las tinciones descritas con la prueba Gold Standard Christmas Tree. Las muestras de líquido seminal pertenecen a pacientes voluntarios que acuden al Hospital General San Juan Riobamba, en el periodo septiembre – octubre 2022. Resultados: Los resultados estuvieron en función de la calidad de imagen microscópica que permitieron establecer las ventajas y desventajas de cada una de las pruebas. Se encontró diferencia estadística significativa entre la sensibilidad de las pruebas experimentales (p-valor < 0,05). Las tinciones Diff Quick y Panóptico mostraron mayor sensibilidad en la identificación de espermatozoides, en estas tinciones además se observa un mayor tamaño de la cabeza del espermatozoide y mostraron un fondo extendido ligeramente sucio en comparación con las demás tinciones. Conclusiones: Las pruebas experimentales evidencian mayor sensibilidad en las tinciones Diff Quick y Panóptico, pero Gram y Papanicolau podrían usarse con este propósito porque se alcanza buena definición morfológica de los espermatozoides.  Área de estudio general: Criminalística. Área de estudio específica: Biología Forense.

Published: June 2023

Boşanma, çeşitli nedenlere bağlı olarak gerçekleşebilmektedir. Bu nedenlerden bazıları ekonomik sebeplere dayanmaktadır. Bu bağlamda çalışmanın amacı, enflasyonun, yetişkin erkek işsizliğin ve kadın istihdamının yetişkin boşanmaları üzerindeki etkilerinin Türkiye Düzey 2 Bölgeleri için araştırılmasıdır. 2005-2021 döneminin ele alındığı çalışmada Driscoll-Kraay (1998) Standart Hatalar Yöntemi kullanılmıştır. Kurulan temel model yetişkin nüfus (25+) ve oluşturulan üç alt yaş grubu (25-34, 35-54 ve 55+) için ayrı ayrı tahmin edilmiştir. Elde edilen sonuçlara göre; 25+, 25-34 ve 35-54 yaş gruplarında yetişkin kadın istihdamı boşanmanın en önemli belirleyicisidir. Yetişkin erkek işsizliğinin ve kadın istihdamının boşanma üzerindeki etkisi ileri yaş evrelerinde önce artmakta sonra azalmaktadır. Enflasyon oranı ise bütün yaş gruplarında boşanmayı pozitif etkilemekte ve etkisi ileri yaş evrelerinde giderek artmaktadır. Ekonomide işsizliğin ve enflasyon oranının düşürülmesine odaklı politikalar ve çalışan kadınlara yönelik düzenlemeler boşanmaların da azalmasını sağlayacaktır. Enflasyonun olumsuz etkilerini hafifletmek için yapılacak sosyal politika tercihlerinde, ileri yaş gruplarının gözetilmesi ayrıca aile birliğinin korunmasına ve toplumsal yapının istikrarına katkıda bulunacaktır.

Published: June 2023

Glomerulocystic kidney (GCK) is defined by a dilatation of the Bowman’s space (greater than 2 times the normal size) of more than 5% of all glomeruli. Although GCK has been occasionally documented in dogs, cats, and humans with renal failure, in fish, reports of spontaneous GCK are rare. For the present study, 2 captive adult red piranhas Pygocentrus nattereri from a closed population were submitted for post-mortem examination. Clinical history included lethargy, inappetence, dyspnea, and altered buoyancy. Macroscopically, the fish displayed coelomic distension and ascites. The kidneys were markedly enlarged and dark yellow. Histologically, Bowman’s space was noticeably dilated, occasionally with atrophic glomerular tufts. Degeneration and necrosis of the tubular epithelium, infiltration, and nephrocalcinosis were also present. To the authors’ knowledge, this present study is the first report of spontaneously occurring GCK in red piranhas and freshwater fish in general. Despite being rare, GCK is a condition with the potential to impair the health of fish and mammals, and further studies are needed to shed new light on this condition.

Published: June 2023

Exploration towards food with cholesterol-lowering property would be beneficial to reduce the incidents of cardiovascular caused by increasing number of people with hypercholesterolaemia.  As much as 42 participants with total cholesterol (TC) levels ≥4.92 mmol/L were studied in a three-arms parallel intervention trial. As much as 72g soy nuts and 66g tempeh were consumed daily (25g soy protein/day) for six weeks, while control group was not given any sample. TC level and body composition were measured before and after the treatment for all groups. In soy nuts group, lower TC level was observed (-0.85±0.82 mmol/L, p<0.05) compared to the control group. Meanwhile in tempeh group, non-significant lower TC level was also observed (-0.40±1.19 mmol/L). Differences in body composition parameters were also measured and resulted in significant lower body weight, fat, and visceral fat in soy nuts group (p<0.05) while in tempeh group, only body weight and waist circumference were significantly decreased (p<0.05). This study suggested that daily consumption of soy nuts and tempeh containing 25g soy protein for six weeks showed a tendency to lower TC levels in hypercholesterolaemic-Indonesian participants. A more significant effect might be observed in subject with higher TC levels; and thus, further study is encouraged.

According to expert consensus, dystonia can be classified as focal, segmental, multifocal, and generalized, based on the affected body distribution. To provide an empirical and data-driven approach to categorizing these distributions, we used a data-driven clustering approach to compare frequency and co-occurrence rates of non-focal dystonia in pre-defined body regions using the Dystonia Coalition (DC) dataset. We analyzed 1,618 participants with isolated non-focal dystonia from the DC database. The analytic approach included construction of frequency tables, variable-wise analysis using hierarchical clustering and independent component analysis (ICA), and case-wise consensus hierarchical clustering to describe associations and clusters for dystonia affecting any combination of eighteen pre-defined body regions. Variable-wise hierarchical clustering demonstrated closest relationships between bilateral upper legs (distance = 0.40), upper and lower face (distance = 0.45), bilateral hands (distance = 0.53), and bilateral feet (distance = 0.53). ICA demonstrated clear grouping for the a) bilateral hands, b) neck, and c) upper and lower face. Case-wise consensus hierarchical clustering at k = 9 identified 3 major clusters. Major clusters consisted primarily of a) cervical dystonia with nearby regions, b) bilateral hand dystonia, and c) cranial dystonia. Our data-driven approach in a large dataset of isolated non-focal dystonia reinforces common segmental patterns in cranial and cervical regions. We observed unexpectedly strong associations between bilateral upper or lower limbs, which suggests that symmetric multifocal patterns may represent a previously underrecognized dystonia subtype.
Do public television channels provide more diversity than private ones?
Authors: Farchy Joëlle
Published: June 2023

Since early 2009 there has been no advertising on French public television channels after 8 p.m. One of the arguments in favour of this reform was that it would promote diversity and that public channels would be less tempted to broadcast homogeneous programming to generate greater advertising revenue. Based on a comparison between British, French and Turkish channels the aim of this paper is to determine whether public channels perform better in terms of diversity than private ones. The paper recalls the reasons why public television channels should differentiate themselves from their private counterparts as far as diversity is concerned. A methodology for assessing diversity, which includes a set of indexes for measuring diversity of programming as well as tools for assessing disparity, is then proposed. Earlier literature finds that public television channels are more diverse than and significantly distinct from their private counterparts. In this exploratory study we will show that, contrary to the literature, public channels have no clear advantage in terms of diversity. Competitive pressure aimed at maximizing viewership plays a role for all channels regardless of their mode of funding, thus leading to greater homogeneity of programming.
Art contribution to cities’ transformation. The role of Public Art management in Italy
Authors: Salice S.
Published: June 2023

Since the mid 80s the evident objective of public art has been to intervene in some infrastructures so that the historical function of a square or of a monument could be re-found with a completely new approach, thus defining a spatial whole as a social whole. Through a qualitative research approach that enlightens artists and commissioning agencies’ points of view, this paper seeks to document the creative processes that characterizes public art and to explore the democratic potential in urban artistic interventions. Although in the past, through instituting public art projects in disadvantaged and fragmented communities, policy makers consciously tried to promote a fallacious sense of shared space, true urban art would not embrace a purely decorative function and would not hesitate to break with the conventions that mark the political use of public art. Even if it is recognized that past expression of public art spoke of universalist and modernist themes, some recent Italian practices of public art are characterized by a strong collaborative effort between the public artist and the community: intended both to design the physical appearance of the city and to rebuild the relationship that underpins urban life. Thus the paper will show how the recognition of the value of public arts can lay the foundations for more integrated urban regeneration strategies driven by cultural policy imperatives.
Cultural heritage policies a tool for development: discourse or harmony?
Authors: Van der Auwera Dr. Sigrid , Schramme dr. Annick
Published: June 2023

In recent decades ‘the notion of “ culture” emerged as the fourth pillar of sustainable development’ (see e.g. Dallaire & Colbert 2012:7). Probably even more than other cultural expressions, cultural heritage is considered as a tool for sustainable development, certainly for the developing world. With this article we want to discuss the notion of sustainable development in the context of cultural heritage policies. Although international policies increasingly point to the value of cultural heritage for sustainable development, we would like to feed the debate on whether and to what extent these cultural heritage policies really contribute to sustainable development or whether these policies can only be classified as policy discourse.
Critical Issues for Research in Arts Management
Authors: Cuyler Antonio C.
Published: June 2023

To develop a more respectable image as a field of inquiry and employment, Dorn (1992) warned that Arts Management needed to create a body of knowledge through scholarly research. To accomplish Dorn’s goal, Arts Management should address three critical issues: (1) the need to establish a discipline and profession specific research agenda, (2) faculty preparedness to conduct and supervise research, and (3) student education in research, to guide the development of Research. Addressing these three issues will ensure Arts Management’s ability to benefit from and protect its intellectual capital while developing a reputation as a viable academic discipline and profession.
From “serving” public arts institutions to creating intercultural contexts: cultural management in Germany and new challenges for training
Authors: Mandel Birgit
Published: June 2023

This essay describes the development of cultural management as a profession and as an academic subject in Germany and discusses new challenges for cultural management according to changes in the cultural sector, enforced by migration, internationalization, and digitalisation. It identifies new working fields and discusses how this is going to change role models of cultural managers. The way academic programmes for arts and cultural management react to these developments, and adapt their curricula and training methods, is described, based on an analysis of university programs in Germany, Austria and Switzerland.
An automated system for polymer wear debris analysis in total disc arthroplasty using convolution neural network

Published: June 2023

Introduction: Polymer wear debris is one of the major concerns in total joint replacements due to wear-induced biological reactions which can lead to osteolysis and joint failure. The wear-induced biological reactions depend on the wear volume, shape and size of the wear debris and their volumetric concentration. The study of wear particles is crucial in analysing the failure modes of the total joint replacements to ensure improved designs and materials are introduced for the next generation of devices. Existing methods of wear debris analysis follow a traditional approach of computer-aided manual identification and segmentation of wear debris which encounters problems such as significant manual effort, time consumption, low accuracy due to user errors and biases, and overall lack of insight into the wear regime.

Methods: This study proposes an automatic particle segmentation algorithm using adaptive thresholding followed by classification using Convolution Neural Network (CNN) to classify ultra-high molecular weight polyethylene polymer wear debris generated from total disc replacements tested in a spine simulator. A CNN takes object pixels as numeric input and uses convolution operations to create feature maps which are used to classify objects.

Results: Classification accuracies of up to 96.49% were achieved for the identification of wear particles. Particle characteristics such as shape, size and area were estimated to generate size and volumetric distribution graphs.

Discussion: The use of computer algorithms and CNN facilitates the analysis of a wider range of wear debris with complex characteristics with significantly fewer resources which results in robust size and volume distribution graphs for the estimation of the osteolytic potential of devices using functional biological activity estimates.
Natural Presentation of Glycosaminoglycans in Synthetic Matrices for 3D Angiogenesis Models
Authors: Zapp Cornelia , Mundinger Patricia , Boehm Heike
Published: June 2023

Glycosaminoglycans (GAGs) are long, linear polysaccharides that occur in the extracellular matrix of higher organisms and are either covalently attached to protein cores, as proteoglycans or in free form. Dependent on their chemical composition and structure, GAGs orchestrate a wide range of essential functions in tissue homeostasis. Accordingly, GAG-based biomaterials play a major role in tissue engineering. Current biomaterials exploit crosslinks between chemically modified GAG chains. Due to modifications along the GAG chains, they are limited in their GAG-protein interactions and accessibility to dissect the biochemical and biophysical properties that govern GAG functions. Herein, a natural presentation of GAGs is achieved by a terminal immobilization of GAGs to a polyethylene glycol (PEG) hydrogel. A physicochemical characterization showed that different end-thiolated GAGs can be incorporated within physiological concentration ranges, while the mechanical properties of the hydrogel are exclusively tunable by the PEG polymer concentration. The functional utility of this approach was illustrated in a 3D cell culture application. Immobilization of end-thiolated hyaluronan enhanced the formation of capillary-like sprouts originating from embedded endothelial cell spheroids. Taken together, the presented PEG/GAG hydrogels create a native microenvironment with fine-tunable mechanobiochemical properties and are an effective tool for studying and employing the bioactivity of GAGs.
