Cinema Demand in Spain: A Cointegration Analysis   总被引：4，自引：3，他引：1  

VÍctor FernÁndez Blanco  JosÉ F. BaÑos Pino 《Journal of Cultural Economics》1997,21(1):57-75

In this paper we explain the decline in cinema attendance in Spain since 1968. We use a cointegration analysis to estimate an individual demand function for cinema, with annual data and in terms of average attendance per inhabitant. We find that cinema is a luxury good and that its demand is elastic with respect to its price. We also show that television acts as a deterrent with regard to cinema attendance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献   

Kinematic,kinetic and EMG analysis of four front crawl flip turn techniques     

Suzana Matheus Pereira  Caroline Ruschel  Marcel Hubert  Leandro Machado  Helio Roesler  Ricardo Jorge Fernandes 《Journal of sports sciences》2015,33(19):2006-2015

This study aimed to analyse the kinematic, kinetic and electromyographic characteristics of four front crawl flip turn technique variants. The variants distinguished from each other by differences in body position (i.e. dorsal, lateral, ventral) during rolling, wall support, pushing and gliding phases. Seventeen highly trained swimmers (17.9 ± 3.2 years old) participated in interventional sessions and performed three trials of each variant, being monitored with a 3-D video system, a force platform and an electromyography (EMG) system. Studied variables: rolling time and distance, wall support time, push-off time, peak force and horizontal impulse at wall support and push-off, centre of mass horizontal velocity at the end of the push-off, gliding time, centre of mass depth, distance, average and final velocity during gliding, total turn time and electrical activity of Gastrocnemius Medialis, Tibialis Anterior, Biceps Femoris and Vastus Lateralis muscles. Depending on the variant, total turn time ranged from 2.37 ± 0.32 to 2.43 ± 0.33 s, push-off force from 1.86 ± 0.33 to 1.92 ± 0.26 BW and centre of mass velocity during gliding from 1.78 ± 0.21 to 1.94 ± 0.22 m · s^?1. The variants were not distinguishable in terms of kinematical, kinetic and EMG parameters during the rolling, wall support, pushing and gliding phases.  相似文献   

Writing instruction for social justice: an investigation into the components of a teacher preparation course     

Émilie Lavoie  Martine Cavanagh 《Literacy》2023,57(2):132-148

Future teachers must notice, navigate, and address ideologies in order to counter inequities in the literacy classroom. This article presents the findings of two teacher educators who have taken up the call to critically reflect on their own underlying beliefs and discourses regarding writing instruction. Through an education design framework, they analysed important components of the course, arguing for a higher degree of visibility of the ideologies and social forces that impact writing instruction. They found that despite encouraging a fairly complex and all-encompassing view of learning to write to the future teachers in their course, the creativity discourse was present passively and the socio-political was downright absent, despite clear social justice aims in the course. They discuss how well-established discourses can serve as gateways to embed the socio-political into the course and address more granularly the question of exclusion through selected mentor texts.  相似文献

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   

Creatine kinase activity weakly correlates to volume completed following upper body resistance exercise     

Machado M  Willardson JM  Silva DR  Frigulha IC  Koch AJ  Souza SC 《Research quarterly for exercise and sport》2012,83(2):276-281

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4156 kg, SD = 867, for 3 min; vs. M = 3503 kg SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r = .45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.  相似文献   

Emergent relations in pigeons following training with temporal samples     

Edson M. Huziwara  Saulo M. Velasco  Gerson Y. Tomanari  Deisy G. de Souza  Armando D. Machado 《Learning & behavior》2013,41(2):192-204

In two experiments, we investigated emergent conditional relations in pigeons using a symbolic matching-to-sample task with temporal stimuli as the samples and hues as the comparisons. Both experiments comprised three phases. In Phase I, pigeons learned to choose a red keylight (R) but not a green keylight (G) after a 1-s signal. They also learned to choose G but not R after a 4-s signal. In Phase II, correct responding consisted of choosing a blue keylight (B) after a 4-s signal and a yellow keylight (Y) after a 16-s signal. Comparisons G and B were both related to the same 4-s sample, whereas comparisons R and Y had no common sample. In Phase III, R and G were presented as samples, and B and Y were presented as the comparisons. The choice of B was correct following G, and the choice of Y was correct following R. If a relation between comparisons that shared a common sample were to emerge, then responding to B given G would be more likely than responding to Y given R. The results were generally consistent with this prediction, suggesting, for the first time in pigeons, the emergence of novel relations that involve temporal stimuli as nodal samples.  相似文献   

Governing Boards in Public Higher Education Institutions: A perspective from the United States     

Taylor  James S.  de Lourdes Machado  Maria 《Tertiary Education and Management》2008,14(3):243-260

Governing boards have a long tradition and prominent role in U.S. higher education. The diversity of institutional types, and thus governing boards, represents a multifaceted tapestry of functions, roles, and responsibilities. This paper will attempt to define the parameters of public higher education governing boards in the USA and offer critical insights into their degree of effectiveness. It is the author’s position that both positive and negative lessons can be learned through an examination of these public governing boards in the USA. The recent emergence of university boards in Europe is examined and their characteristics are compared against the characteristics of public and private boards in the USA.

Motivational Profile and Academic Achievement Among Students Enrolled in Different Schooling Tracks     

THÉRÈSE BOUFFARD  NATHALIE COUTURE 《Educational studies》2003,29(1):19-38

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement.  相似文献
