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

As a mixture of new technologies, processes and services oriented to the citizen, e-government has become one of the most important keywords for the public sector reform with proponents claiming that it guarantees transparency, accountability and better communication between local and national administrations and their public. Few if any studies have investigated the factors that might contribute to the establishment of trusting relationship between city councils and citizens. This paper examines the relative importance and significance of three types of information communication technologies (ICTs) towards the use of e-government and the development of civic engagement. We conduct an empirical investigation of 179 Spanish official town websites (web sites in the municipalities). The research findings suggest that implementing ICT not only involves a step towards an increase in the use of e-government services by people, but also provides numerous opportunities for their civic engagement. The main conclusion of this study is that although ICT can leverage the adoption of e-government, it cannot create alone engagement with traditional activities of the local government. What is missing from this relationship is a mediating variable (adoption of e-government by government officers), which in turn can greatly help to better understand how ICT impacts relationships between governments and their citizens. 相似文献

PurposeThe purpose of this study was to compare established methods with newly-developed methods for estimating the total energy expenditure (TEE).MethodsThe study subjects comprised 46 individuals, including 16 middle-aged men (mean age 51.4 years), 14 middle-aged women (mean age 49.9 years) and 16 young women (mean age 19.1 years). The TEE was estimated from 24-h heart rate (HR) data using newly-developed software (MoveSense HRAnalyzer 2011a, RC1, Suunto Oy, Vantaa, Finland), and was compared against the TEE determined using doubly labeled water (DLW). Agreement between the two methods was analyzed using Bland and Altman plots.ResultsThe HR method yielded similar TEE values as the DLW method at the group level, with an average of 8.6 kcal/day in the difference in the mean, but with large individual variations. Forty-four (96%) out of 46 subjects fell within ±2SD of the mean difference in TEE comparisons, and there was no tendency towards under- or over-estimation.ConclusionOur results indicate that the current software using HR analysis for the estimation of daily TEE needs further development for use with free-living individuals. 相似文献

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

This paper explores the use of thinking aloud made by young people who have sustained a severe acquired brain injury (ABI). The phenomenon is compared with the concepts of egocentric speech and inner speech before the form of thinking aloud by pupils with ABI is examined. It is suggested that by using thinking aloud, this group of pupils is able to engage in internally persuasive dialogue and is therefore enabled to take part in classroom learning. 相似文献

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

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

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

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

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
