Influence of regression model and incremental test protocol on the relationship between lactate threshold using the maximal-deviation method and performance in female runners     

Machado FA  Nakamura FY  Moraes SM 《Journal of sports sciences》2012,30(12):1267-1274

This study examined the influence of the regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and the endurance performance. Sixteen non-competitive, recreational female runners performed a discontinuous incremental treadmill test. The initial speed was set at 7 km · h?1, and increased every 3 min by 1 km · h?1 with a 30-s rest between the stages used for earlobe capillary blood sample collection. Lactate-speed data were fitted by an exponential-plus-constant and a third-order polynomial equation. The lactate threshold was determined for both regression equations, using all the coordinates, excluding the first and excluding the first and second initial points. Mean speed of a 10-km road race was the performance index (3.04 ± 0.22 m · s?1). The exponentially-derived lactate threshold had a higher correlation (0.98 ≤ r ≤ 0.99) and smaller standard error of estimate (SEE) (0.04 ≤ SEE ≤ 0.05 m · s?1) with performance than the polynomially-derived equivalent (0.83 ≤ r ≤ 0.89; 0.10 ≤ SEE ≤ 0.13 m · s?1). The exponential lactate threshold was greater than the polynomial equivalent (P < 0.05). The results suggest that the exponential lactate threshold is a valid performance index that is independent of the initial intensity of the incremental test and better than the polynomial equivalent.  相似文献   

An approach to web-based Personal Health Records filtering using fuzzy prototypes and data quality criteria     

Francisco P. Romero  Ismael CaballeroJesus Serrano-Guerrero  Jose A. Olivas 《Information processing & management》2012

Nowadays, new ways of managing and accessing to health-care information are continuously appearing. Web-based Personal Health Records (web PHRs) have the potential to make data about health-care available to clinicians, researchers and students in different medical contexts and applications. Therefore, the amount of web PHRs accessible through Internet has grown enormously and as a result health-care professionals are currently burdened with more and more data. It’s probable that these data, unfortunately, have not always the adequate levels of quality, making that their work cannot always be as successful as expected. As a way of alleviating this fact, the present work is focused on improving the document filtering results in the context of web PHRs management. To achieve this goal, a new kind of document filtering model is proposed. This model is based on fuzzy prototypes which are defined by means of conceptual prototypes. These prototypes are obtained by using a data quality analysis of documents. This analysis guarantees that filtered information will be relevant enough for the information user. The complete model provides an efficient strategy of document filtering that can be very useful when it is necessary to deal with a constant flow of new information.  相似文献   

Generation of virtual models of cultural heritage     

Amparo Núñez Andrés  Felipe Buill Pozuelo  Joaquín Regot Marimón  Andrés de Mesa Gisbert 《Journal of Cultural Heritage》2012,13(1):103-106

Different techniques and tools currently exist to generate three-dimensional models of small elements, buildings and cities. Apart from being easier to interpret than two-dimensional drawings, these models facilitate data necessary for reconstruction projects, preservation or rehabilitation of the architectural or archaeological heritage. Traditional surveying only enables us to obtain discrete information of the characteristic lines that define each surface, edge, slope change etc. whereas work with massive capture techniques allows us to obtain continuous points of the surfaces. Photogrammetry or laser scanning combined with conventional photography provides information of the building in addition to its geometry. We carried out a review of the different techniques showing the advantages and disadvantages of each technique as well as the information that can be obtained by applying these techniques to the survey of the great Gate of Antioch in the town of Aleppo, declared a World Heritage Site by UNESCO in 1986, in Syria.  相似文献   

Web technologies applied to virtual heritage: An example of an Iberian Art Museum     

María Dolores Robles-Ortega  Francisco R. Feito  Juan J. Jiménez  Rafael J. Segura 《Journal of Cultural Heritage》2012,13(3):326-331

Nowadays, some virtual museums include 3D room scenes to show the models of its pieces, just like in real museums. Nevertheless, the generation and maintenance of this kind of scenes is generally difficult and should be done by an expert. For example, any change such as including a new piece or modifying the position of an existing fragment usually requires a different design and the creation of a new scene. In this paper we present a case study on the development of a web-based application to automatize this process. To this end, a database to store both graphic and non-graphic information about the pieces, and some 3D rooms to show them has been created. The designed scenes only contain some pieces of furniture to exhibit the fragments, which will be subsequently included. Thus, when a room is loaded in the web page, its associated pieces are obtained through a query in the database and its models are dynamically included in the original scene. Therefore, the position changes or the inclusion of new pieces are not performed in the 3D model, but in the database. Our application makes the transmission of the knowledge to the general public easier because any new discovered piece can be included in a existing museum effortlessly.  相似文献   

Training and psychosocial patterns during the early development of Portuguese national team athletes     

André Barreiros  Jean Côté  António Manuel Fonseca 《High Ability Studies》2013,24(1):49-61

This study explored the early development of expert athletes compared to a group of athletes that did not achieve an expert level of performance despite being involved in youth events with their national squads. In particular, the activities, training patterns, and psychosocial influences that characterized their paths in competitive sports were examined. Male and female participants (N?=?42) from different sports were interviewed. Overall, athletes showed several commonalities. However, experts were selected to national squads later and also started thinking about investing in becoming elite athletes later. Non-experts revealed more parental pressure and less individual training with coaches.  相似文献   

The chameleon on a tartan rug: adaptations of three academic developers’ professional identities     

Barbara Kensington-Miller  Joanna Renc-Roe  Susan Morón-García 《International Journal for Academic Development》2013,18(3):279-290

This paper builds on discussions of academic developers’ identity experienced as a discomfiting, troubled, and often marginal space. Three experienced academic developers, located in research-intensive institutions in three different countries, using auto-ethnographic writing and a shared narrative inquiry, explore moments of congruence and conflict. While there are elements that sustain them in their job, the categorisation of their role can impact on their ability to do their job, undermining their credibility. This can prevent them from engaging in research that could enrich practice in their institutions and inform institutional strategy or change the culture in teaching and learning. Instead they are forced into discomfit: having to defend their right to be involved in the institutional discussions. The most worrying issue is the pervasive trend in the change of academic developers’ status (from tenure-track academic peers to professionals).  相似文献   

Hidden voices in higher education: inclusive policies and practices in social science and law classrooms     

Rosario López Gavira 《International Journal of Inclusive Education》2013,17(4):365-378

This paper pertains to a broader biographical-narrative research project which studies barriers and support as identified by students with disabilities at a Spanish University (Barriers and Support That Disabled Students Identify in the University. Project funded by the Spanish Ministry of Science and Innovation (Dir. Dr Anabel Moriña; Ref. EDU 2010–16264, 2010–2014)). The present study focuses specifically on barriers and support identified by students with disabilities enrolled in undergraduate programmes in the Social Sciences and Law. The purpose of this paper is to analyse, from the point of view of disabled students (applying the biographic-narrative methodology), which barriers and which support this group encounters in Higher Education. To this end, findings are organised in the following categories: general institutional data; infrastructure, architectural and accessibility-related data; faculty and teaching-related data; data relating to fellow students; and suggestions for improving the university and/or university classrooms. In the Conclusions section, we return to our earlier discussion of key findings which shed some light on how the University helps or hinders learning among participants in the study. From this perspective, taking as a reference the social model of disability, we conclude that in order to be inclusive, the University needs to commit itself to adopting proactive measures that eliminate the barriers that do not permit the learning and the full participation of the students in question.  相似文献   

Evaluating implementation of the International Classification of Functioning,Disability and Health in Portugal's special education law     

Manuela Sanches-Ferreira  Rune J. Simeonsson  Mónica Silveira-Maia  Sílvia Alves 《International Journal of Inclusive Education》2013,17(5):457-468

This paper reports the results of a national two-year project, commissioned by the Portuguese Ministry of Education, to investigate the implementation of the International Classification of Functioning, Disability and Health (ICF) under Decree-Law 3/2008. The Decree-Law also introduced the principle that the documentation of students' functioning profiles should be the basis for eligibility decision-making – replacing the need of a diagnosis. Of specific interest was the study of the ICF implementation in the assessment, eligibility and intervention processes of students in need of specialised supports. To that end, the study was based on a document analysis of case records of 214 students. The analysis of functioning profiles showed that the ICF use promoted a functional approach in students' assessment. In addition, the use of the ICF contributed to the differentiation of eligible and non-eligible students based on their functioning profiles and addressed the most suitable educational interventions within the Individualised Education Plans.  相似文献   

Schooling sexualities and gendered bodies. Experiences of LGBT students in Icelandic upper secondary schools     

Jón Ingvar Kjaran  Guðrún Kristinsdóttir 《International Journal of Inclusive Education》2013,17(9):978-993

In this paper, we study how Lesbian, Gay, Bisexual and Transgender people (LGBT) students in Icelandic upper secondary schools interpret their experience of heteronormative environment and how they respond to it. The aim is to explore how sexualities and gendered bodies are constructed through ‘schooling’. The article draws on interview data with seven LGBT students who attended five different upper secondary schools. We also use visual data collected during fieldwork at one upper secondary school and exemplify the results with a poster and a digitalised short-film, produced by the students, to substantiate what participants told us in the interviews. All of the students experienced heteronormative discourse and lack of respect and indicated that they did not feel fully accepted in school. Upon entering the classroom, the visibility of LGBTs and discussion about different performances of gender and sexuality seem to disappear, whether in terms of textbooks, course content, teaching practices and school environment. Furthermore, LGBTs and those who do not conform to the hegemonic performances of gender are often constructed as deviations from the norm, strange, and even depicted as the abjected other. This applies in particular to the informal school, which embraces the traditions, culture and social interactions among students and teachers. This othering occurs, despite relatively positive attitudes towards LGBT people in Icelandic society in general. The results signify a gap between policy and practice as regards the positioning of LBGT students, which affects their schooling and well-being.  相似文献   

Reducing subjectivity in special education referrals by educators working with Latino students: using functional behavioral assessment as a pre-referral practice in student support teams     

Gerardo Moreno  Francisco X. Gaytán 《Emotional and Behavioural Difficulties》2013,18(1):88-101

Over the past several decades, the Latino population throughout the USA has demonstrated significant growth and exceeded that of other ethnic minority groups. This influx is particularly evident in the student enrollment of US schools as the number of Latino students has increased by approximately 10 million within the past 10 years. With this dramatic increase, there are a number of critical issues that present significant barriers to a high-quality educational experience for Latino students, specifically overrepresentation of Latinos receiving disciplinary actions and the high number of referrals to special education evaluation for emotional and behavioral disorders. This paper will discuss the impact of the Latino population in US schools, the concern of overrepresentation and biased referrals, and the use of a culturally attuned functional behavioral assessment as a pragmatic solution to better serve this growing population.  相似文献
