Through Musical Communication to Development of Competence in Culture Awareness and Expression

This study presents an example of a music workshop which brought together pupils and students of different music schools, students of musicology, composition and classroom teaching, teachers, professors and composer on the common topics in contemporary music. The purpose of the workshop was to encourage an active and creative participation of everybody involved in a way that went beyond the usual practice used in cultural activities in education. In this respect, the workshop emphasised the importance of the creative expression of experience, ideas and emotions in the field of music. The results of the interview, which were conducted by some of the workshop participants, point out the complex occurrence of various indicators, which at the level of personal and social factors have determined the nature of communication through contemporary music and indirectly influenced the development of competence in cultural awareness and expression. Challenges identified included students＇ lack of musical experiences for contemporary music at all educational levels, the low priority given to contemporary music in schools as well as teachers＇ lack of professional knowledge in this field. The study highlights the need for more experience in contemporary musical language in general and music professional schools.     

Wie fach(un)abhängig ist bildungswissenschaftliches Wissen?

General pedagogical knowledge (GK) as part of teachers’ professional knowledge has been receiving increasing attention in empirical research. Current results are based on the assumption that GK is conceptualized and acquired during teacher education independent from the subjects being studied. Therefore, we examine whether GK can be measured comparably across subjects and whether differences exist among teachers from different subject specializations concerning their level of GK. Results from 2616 preservice teachers starting their induction phase indicate that knowledge can be invariantly measured across three subject groups, i.?e., science, languages/humanities and a combination of these subjects. However, teachers vary systematically depending on their subject specializations (controlling for gender, language, grade point average, and school track). Science teachers achieve higher test scores for diagnostic/evaluation and lower scores in fields more removed from direct instruction (e.?g., theory of education). There are no differences concerning knowledge directly related to instruction (e.?g., learning/development). Results are discussed with reference to subject-related factors of socialisation, selection and development in the profession.     

Peer Influence on Ethnic‐Racial Identity Development: A Multi‐Site Investigation

The peer context features prominently in theory, and increasingly in empirical research, about ethnic‐racial identity (ERI) development, but no studies have assessed peer influence on ERI using methods designed to properly assess peer influence. We examined peer influence on ERI centrality, private, and public regard using longitudinal social network analysis. Data were drawn from two sites: a predominantly Latina/o Southwestern (SW) school (N = 1034; Mage = 12.10) and a diverse Midwestern (MW) school (N = 513; Mage = 11.99). Findings showed that peers influenced each other's public regard over time at both sites. However, peer influence on centrality was evident in the SW site, whereas peer influence on private regard was evident in the MW site. Importantly, peer influence was evident after controlling for selection effects. Our integration of developmental, contextual, and social network perspectives offers a fruitful approach to explicate how ERI content may shift in early adolescence as a function of peer influence.     

“Immigrant” in Russian and French Print Media (Linguistic and Visual Composition Analyses)

This study addresses the representation of the linguistic and cultural type “immigrant” in French and Russian media discourse. Linguistic analysis of selected sources shows, on the one hand, signs of tolerance towards immigrants and, on the other hand, evidence of rejecting immigrants, which demonstrates the ambiguity of the matter and indirectly provokes conflicts. Visual composition analysis complements these results by revealing the following: the purpose of immigration – employment – is often socially rejected; immigrants’ sense of community is a specific cultural code in a host culture; and the cultural transfer of an “immigrant” into a different space creates uncertainty or ambiguity.     

The whole day matters: Understanding 24-hour movement guideline adherence and relationships with health indicators across the lifespan

BackgroundNew research suggests that the composition (mix) of movement behaviors within a 24-h period may have important implications for health across the lifespan. Consistent with this integrated movement behavior paradigm, a number of countries across the world have developed and released 24-h movement guidelines for specific age groups. The purpose of this systematic review was to examine the associations between the 24-h time-use composition of movement behaviors, or adherence to 24-h movement guidelines, and multiple health indicators across the lifespan.MethodsFive online databases (PsycINFO, PubMed, SPORTDiscus, Web of Science, and Ovid MEDLINE) were searched for relevant peer-reviewed studies published between January 2015 and January 2020 that met the a priori inclusion criteria, with no study design limits. The methodological quality of research evidence for each individual study and for each health indicator was assessed by using a modified version of the Downs and Black checklist.ResultsA total of 51 studies from 20 different countries met the inclusion criteria. A total of 31 studies examined adherence (meeting vs. not meeting) to 24-h movement guidelines, and 20 studies used compositional analyses to explore the 24-h time-use composition of movement behaviors. Findings indicated that meeting the 24-h movement guidelines were (1) not associated with adiposity among toddlers, (2) favorably associated with health-related quality of life, social-cognitive development, and behavioral and emotional problems among preschoolers, (3) favorably associated with global cognition, health-related quality of life, and healthy dietary patterns in children, and (4) favorably associated with adiposity, fitness, and cardiometabolic, mental, social, and emotional health among children and youth. Significant associations were also found between the composition of 24-h movement behaviors and indicators of (1) adiposity and bone and skeletal health among preschoolers, (2) health-related quality of life among children, (3) adiposity, fitness, and cardiometabolic, social, and emotional health among children and youth, (4) cardiometabolic health in adults, (5) adiposity and fitness among adults and older adults, and (6) mental health and risk of mortality among older adults. The quality of the available evidence ranged from poor to good.ConclusionThe current evidence indicates that the composition of movement behaviors within a 24-h period may have important implications for health at all ages and that meeting the current 24-h movement guidelines is associated with a number of desirable health indicators in children and youth. Future studies should employ longitudinal and experimental designs, include valid and reliable measures of 24-h movement behaviors, and examine a wide array of health indicators across all age groups. Such studies would confirm the results from the primarily cross-sectional evidence drawn from studies included in our review and further advance our understanding of the relationships between 24-h movement behaviors and health.     

Aerodynamic behaviour of single sport jersey fabrics with different roughness and cover factors

Wind tunnel testing has been carried out on nine-knitted single jersey fabrics (100% polyester) using cylinder and leg models to determine its aerodynamic behaviour over a range of speeds (20–80 km/h) representative of sports activities. Strong correlation between fabric manufacturing (cover factor) and fabric roughness and aerodynamic parameters has been established. Similar aerodynamic behaviour of fabrics was observed when tested on the cylinder model and on the leg model.     

Do oarsmen have asymmetries in the strength of their back and leg muscles?

The aim of this study was to establish whether asymmetry of the strength of the leg and trunk musculature is more prominent in rowers than in controls. Nineteen oarsmen and 20 male controls matched for age, height and body mass performed a series of isokinetic and isometric strength tests on an isokinetic dynamometer. These strength tests focused on the trunk and leg muscles. Comparisons of strength were made between and within groups for right and left symmetry patterns, hamstring :quadriceps ratios, and trunk flexor and extensor ratios. The results revealed no left and right asymmetries in either the knee extensor or flexor strength parameters (including both isometric and isokinetic measures). Knee extensor strength was significantly greater in the rowing population, but knee flexor strength was similar between the two groups. No difference was seen between the groups for the hamstring:quadriceps strength ratio. In the rowing population, stroke side had no influence on leg strength. No differences were observed in the isometric strength of the trunk flexors and extensors between groups, although EMG activity was significantly higher in the rowing population. Patterns of asymmetry of muscle activity were observed between the left and right erector spinae muscles during extension, which was significantly related to rowing side ( P < 0.01). These observations could be related to the high incidence of low back pain in oarsmen.     

Digital preservation of Brazilian indigenous artworks: Generating high quality textures for 3D models

Three-dimensional (3D) digital preservation aims at generating 3D models of objects that have cultural or scientific value. It allows realistic visualization of objects through virtual museums or scientific applications, and the restoration of the preserved object in case of natural wear or accidents. This work contributes to this research area by presenting a method to improve color texture quality of 3D models obtained from color and depth images of a laser scanner. Although this device offers precise depth information, the resulting color information is still poor and limits the generation of realistic textures. Our approach is to capture photographs of the object with a high-resolution digital camera and use them to generate a new color texture for the 3D model. Our work proposes a practical technique, easy to replicate, to generate high quality textures for 3D models from photographs. The method is composed by three main steps: (1) calibration of the image acquisition devices; (2) data acquisition; and (3) texture generation. In this paper, we detail our color texture generation method and apply it on the digital preservation of many artworks made by native Brazilians (indians) from the Wauja and Karaja communities. These indigenous communities are acknowledged as great ceramic artists, each bearing their own main themes, using a very rich symbolism in their paintings. Their artworks represent important aspects of the native South American culture and their digital preservation is motivated by three main reasons: (1) their fragility; (2) the paintings loose their original appearance with time; and (3) the possibility of extinction of these communities. We present several results of preserved artworks with enhanced quality realistic texture maps. Also, we present a methodology to analyze the quality and accuracy of texture maps. The resulting 3D models can be visualized through a tool we developed to support the virtual exhibit of 3D preserved heritage.     

3D preserving xviii century barroque masterpiece: Challenges and results on the digital preservation of Aleijadinho's sculpture of the Prophet Joel

We present our recent efforts in the digital preservation of a set of baroque sculptures made by Antônio Francisco Lisboa, known as O. Aleijadinho, which is an important American baroque artist. The set was made in the beginning of the xix century and is composed of 12 near real sized sculptures, hand-carved in soapstone. These sculptures represent 12 of the 16 prophets from the Holy Bible and are part of a UNESCO World Heritage Site. Our group has been collaborating with UNESCO in a project that aims to preserve all these statues. We hereby present our initial efforts, consisting of the 3D digital preservation of the Prophet Joel sculpture. We developed a complete 3D digital preservation pipeline composed of four main stages: data acquisition, 3D reconstruction, texture generation and 3D model visualization. By evaluating our results in this first sculpture, we discuss the improvements we conceived before applying our pipeline in the remaining ones. Finally, we present the 3D model of the Prophet which registers the sculpture's current state and will be used in restoration, research and educational activities. We believe this contribution may be useful to guide further research on similar scenarios, showing how to avoid some practical mistakes and achieve good results.     

The –ography of markets (or,the responsibilities of market studies)

How should we write about markets? What responsibilities does this writing bring upon us? This paper offers an immanent critique of ‘market studies’ scholarship, and through this a call to reflection and reformed action. Turning the intellectual framework of market studies upon itself, we come to see its texts as performative and agential. We discuss these qualities and the associated responsibilities via a reading of literature from the domain of ethnography. An auto-ethnographic sketch of market writing allows us to consider the problematic nature of expertise for market studies scholars and the agency and power of our texts. We find a dual moment of performativity from which our texts emerge more powerful than their authors. On this basis we offer a vision of critical interventions embedded in our texts, underpinned by the intellectual axioms of the market studies programme.
