On many occasions, the graphic information handled by people working in the cultural heritage sector is still bidimensional. Layouts showing elevations and cross sections are the most widespread tools. However, there is an increased need for carefully detailing the complexity of valuable sites with an improved accuracy. This implies the measuring and handling of three-dimensional data, using both commercial and turn-key hardware and software solutions. Taking the usual traditional process as a reference, in the present paper a new effective methodology for carrying out computer assisted delineation of layouts from cultural heritage sites, using 3D digital models, is described. The proposed procedure has been tested in five intervention projects on representative churches within the “Merindad de Aguilar de Campoo” medieval area, in the north of Spain.¹ This area has the largest collection of Romanesque art in the world, and is currently under European Heritage Site and World Heritage Site declaration process by the UNESCO.  相似文献   

The Culture of Mexican-Americans: Its Importance for Early Childhood Educators     

Olivia N. Saracho  Frances Martínez-Hancock 《Multicultural Perspectives》2013,15(2):43-50

This paper provides an introduction to the Mexican-American culture, describing (1) cultural diversity and linguistic policies in the United States; (2) cultural and linguistic studies that have examined the backgrounds of Mexican-American individuals; (3) the characteristics of this population; (4) issues on discrimination and human relations; (5) the socioeconomic factors that Mexican-American individuals encountered due to their lack of education; and (6) the predominance of poorly paid and undereducated unskilled workers. Although many Mexican Americans have moved up the social ladder to the middle class, others have not. However, they have a richness of language and culture to share with the school.  相似文献

Why Do I Feel I Don’t Belong to the Brazil on TV?     

Antonio C. La Pastina  Joseph D. Straubhaar  Lirian Sifuentes 《Popular Communication》2014,12(2):104-116

Telenovelas have been considered the predominant popular genre on television, the most widely available and popular national medium, in Brazil, for more than 30 years (Straubhaar, 1982). However, we argue in this article that although telenovelas do indeed have this remarkable penetration and popularity in Brazil, their reception is mediated by audience class, geographical location, race, and issues with media content. Many in the audience feel disenfranchised from the dominant telenovela representations, particularly on the primary network, TV Globo, because of their rural, Northeastern status and identity, or their Afro-Brazilian identity. They question their sense of belonging, not because they do not feel Brazilian, but because the “Brazil” they see on TV does not include them.  相似文献

Reference values and improvement of aerodynamic drag in professional cyclists   总被引：4，自引：1，他引：3  

García-López J  Rodríguez-Marroyo JA  Juneau CE  Peleteiro J  Martínez AC  Villa JG 《Journal of sports sciences》2008,26(3):277-286

The aims of this study were to measure the aerodynamic drag in professional cyclists, to obtain aerodynamic drag reference values in static and effort positions, to improve the cyclists' aerodynamic drag by modifying their position and cycle equipment, and to evaluate the advantages and disadvantages of these modifications. The study was performed in a wind tunnel with five professional cyclists. Four positions were assessed with a time-trial bike and one position with a standard racing bike. In all positions, aerodynamic drag and kinematic variables were recorded. The drag area for the time-trial bike was 31% higher in the effort than static position, and lower than for the standard racing bike. Changes in the cyclists' position decreased the aerodynamic drag by 14%. The aero-helmet was not favourable for all cyclists. The reliability of aerodynamic drag measures in the wind tunnel was high (r > 0.96, coefficient of variation < 2%). In conclusion, we measured and improved the aerodynamic drag in professional cyclists. Our results were better than those of other researchers who did not assess aerodynamic drag during effort at race pace and who employed different wheels. The efficiency of the aero-helmet, and the validity, reliability, and sensitivity of the wind tunnel and aerodynamic field testing were addressed.  相似文献   

Activity profile of top-class association football referees in relation to fitness-test performance and match standard   总被引：1，自引：1，他引：0  

Mallo J  Navarro E  Aranda JM  Helsen WF 《Journal of sports sciences》2009,27(1):9-17

The aim of this study was to examine the kinematic activity profiles, cardiovascular responses and physical fitness of top-class football referees (n=11) during the FIFA Confederations Cup 2005. Computerised match-analyses (n=9) were performed with a two-dimensional photogrammetric video system, and the cardiovascular demand imposed on the referees (n=12) was measured using heart rate recordings. Total distance covered was 10,218, s=643 m of which 3531, s=510 m was covered at high intensities (>3.6 m.s(-1)). Both total distance covered (r2=0.59; P=0.02) and high-intensity activities (r2=0.44; P=0.05) were related to the distance covered by the ball in the same match. The referees ran at high speed 37% further (P=0.01) in the actual tournament than during under-17 top-level officiating. After the 5-min interval during which high-speed running peaked, in the following 5 min the performance was reduced by 19% (P=0.01) in relation to the mean of the game. Mean heart rate was 161, s=9 b.min(-1) (86, s=3% of maximal heart rate (HRmax)). Mean heart rate (expressed as percentage of HRmax) was related in part (r2=0.36; P<0.01) to the number of high-intensity activities performed in the same 5-min interval. The results of this study show that: (1) kinematic activity profiles of top-class referees can be influenced by the distance covered by the ball; (2) the amount of high-speed running (>5 m.s(-1)) best describes the physical performance of referees; (3) heart rate recording can be a useful tool to determine the most intense periods of a match and (4) the new fitness tests adopted by FIFA were poor predictors of match activities.  相似文献   

Determinants of possession of the ball in soccer   总被引：1，自引：0，他引：1  

Lago C  Martín R 《Journal of sports sciences》2007,25(9):969-974

In research on the importance of the possession of the ball in soccer, little attention has been paid to its determinants. Using data from 170 matches of the 2003 - 2004 Spanish Soccer League, we explain why differences in the possession of the ball among teams are so great. In particular, four variables are examined: evolving match status (i.e. whether the team is winning, losing or drawing), venue (i.e. playing at home or away), and the identities of the team and the opponent in each match. Results of linear regression analysis show that these four variables are statistically significant and together explain most of the variance in possession. In short, home teams have more possession than away teams, teams have more possession when they are losing matches than when winning or drawing, and the identity of the opponent matters - the worse the opponent, the greater the possession of the ball. Combinations of these variables could be used to develop a model that predicts possession in soccer.  相似文献   

Cell-in-cell phenomenon in urinary sediment: a case report     

Carlos Martínez-Figueroa  Karen Corts-Sarabia  Jos Antonio Tesser Poloni  Enrique Alejandro Molina-Avilez  Luis A. Palaoro  Amalia Vences-Velzquez 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2022,32(2)

The internalization of apoptotic cells by non-phagocytic cells has been observed in different tissues and could be an important mechanism for the elimination of dying cells. Here, we describe a probable event of phagocytosis of apoptotic cells mediated by urothelial cells in urinary sediment. A 90-years-old male patient was admitted unconscious to the hospital, visible signs included: pale skin and dry mucous membranes, presumptively diagnosed as dehydration. Blood test revealed anaemia (haemoglobin 130 g/L) and hyperglycaemia (glucose 7.8 mmol/L), urinalysis showed a picture of urinary tract infection (leukocyturia and bacteriuria). The microscopic analysis of urinary sediment revealed the presence of urothelial cells and leukocytes internalized in urothelial cells. Anti-CD68 (membrane marker of macrophages) was tested by immunocytochemistry and a negative result was observed. Based on the findings phagocytosis of apoptotic cells mediated by urothelial cells was identified. This phenomenon can be observed in urinary sediment and should not be confused with a neoplastic process since it is a physiological event of cell elimination.  相似文献
