Improving comprehension online: effects of deep vocabulary instruction with bilingual and monolingual fifth graders     

C. Patrick Proctor  Bridget Dalton  Paola Uccelli  Gina Biancarosa  Elaine Mo  Catherine Snow  Sabina Neugebauer 《Reading and writing》2011,24(5):517-544

This quasi-experimental study investigated the effects of an Internet-delivered universally designed depth of vocabulary intervention that targeted both English-speaking and Spanish–English-speaking students. Two hundred forty students, 49% of whom were Spanish–English bilinguals, participated in the 16-week intervention. Intervention students read eight multimedia texts with embedded instruction on 40 words and reading strategy support. Students could access all texts and activities in Spanish and English. In comparison to a control group, there were significant intervention effects on a standardized measure of vocabulary knowledge, but effects were non-significant for comprehension. Similarly, significant effects on researcher-developed measures of vocabulary depth were detected, but not for a researcher-developed measure of breadth.  相似文献   

Developing a Performance Measurement System for University Central Administrative Services     

Marika Arena  Michela Arnaboldi  Giovanni Azzone  Paola Carlucci 《Higher Education Quarterly》2009,63(3):237-263

Central administrative services have recently received increasing attention from practitioners and academics due to the challenging need to both manage scarce resources and provide high-quality services. In this context, performance measurement systems (PMSs) may assume a central role, although an unresolved debate remains on the claimed benefits of accountability and the difficulties that have emerged in defining and managing proper measures. This paper contributes to this debate by presenting the results of a study in which a PMS for central administrative services has been developed and tested through an action research approach drawing on actor network theory. The experiment was carried out in 15 Italian universities and five areas of services were dealt with: student support, research support, accounting, human resources, and logistics and procurement. The highly participative method resulted in a comparable system with a complete set of cost and quality indicators across the participating universities. These data proved to be useful at managerial and policy level, providing insights on the presence of scale effects and on the relative importance of quality dimensions for users of services. Participating in the project encouraged the university staff to use indicators in decision making.  相似文献   

Is sports science answering the call for interdisciplinary research? A systematic review     

Ben Piggott  Sean Müller  Paola Chivers  Carmen Papaluca  Gerard Hoyne 《European Journal of Sport Science》2019,19(3):267-286

Sports science research is traditionally monodisciplinary despite calls for an interdisciplinary focus. The primary purpose of this systematic review was to identify studies on talent identification, talent selection and competition performance to determine whether interdisciplinary research is being conducted. Thirty-six studies met the selection criteria. These studies were critiqued relative to sport, skill level, sport science sub-disciplines included, and whether the research was multidisciplinary or interdisciplinary. The secondary purpose of the review was to critique the level of analysis and level of representative task design in performance tests used in the studies. Twenty-five studies were categorised as interdisciplinary, with 11 categorised as multidisciplinary. Thirteen sports were represented with soccer the most frequent followed by field hockey, Australian Rules football, handball and rugby league. Thirty-two studies completed their analysis at a group level and four at an individual level. A total of 337 performance tests were rated for representative task design with 64 categorised as low, 123 as medium and 150 as high. The results pertaining to interdisciplinary studies and individual analyses are discussed in relation to constraints theory, which predicts that interacting variables can explain sport performance. Sports science research is beginning to fulfil the call for interdisciplinary research. Future research, however, needs to consider individual analyses and representative task design of tests to progress sports science knowledge.  相似文献   

Children of Alcoholics in the schools: Where are they? their representation in special education     

Robert Stern  Andrea Kendall  Paola Eberhard 《Psychology in the schools》1991,28(2):116-123

The hypothesis that there is a greater frequency of children of alcoholics in special classes for Emotional/Behavioral Disordered (ED) and Learning Disabled (LD) children was explored. A random sample of students in ED, LD, and regular classes was selected and administered the Children of Alcoholics Screening Test. Parents completed the Friel Co-Dependency Assessment Inventory. An analysis of variance in CAST and FCAI scores did not reveal any significant differences among groups. Significant differences were noted in the relationship of marital status and chemical dependency in immediate family. Reported incidence of chemical dependency in the immediate family was identified as a concern warranting further exploration. Issues that may have affected the study such as sample size, respondent participation, and various roles exhibited in the family were considered. The possible impact alcoholism has on children and appropriate program intervention in the schools were discussed.  相似文献   

A new family of high viscosity polymeric dispersions for cleaning easel paintings     

Emiliano Carretti  Irene Natali  Caterina Matarrese  Paola Bracco  Richard G. Weiss  Piero Baglioni  Antonella Salvini  Luigi Dei   《Journal of Cultural Heritage》2010,11(4):1555-380

The procedures for making and applying a new family of high viscosity aqueous polymeric dispersions based on poly(vinyl alcohol)-borax (PVA-borax) matrices are presented. A specific system of this type has been used to remove an oxidized varnish coating from the surface of “Coronation of the Virgin with Saints”, a 15th century egg tempera painting on wood by Neri di Bicci (Florence, 1418–1492). FTIR spectra showed that the oxidized varnish was constituted of highly aged shellac resin. Good cleaning performance was attained when the liquid portion of the dispersion consisted of a mixture of water and acetone. Rheological investigations indicate that the acetone content does not affect the mechanical properties of the polymeric dispersion. Those mechanical properties permit easy removal of the cleaning agent simply by peeling it from the surface by means of a forceps or spatula once it has carried out its cleaning function. Optical microscopic and FTIR investigations show that the cleaning agent is able to remove the oxidized varnish coating from the surface of the Neri di Bicci painting without leaving detectable residues.  相似文献   

Market information approaches, product innovativeness, and firm performance: An empirical study in the fashion industry     

Paola Cillo  Luigi M. De Luca  Gabriele Troilo 《Research Policy》2010,39(9):1242-1252

In this study the authors propose a distinction between two approaches to market information, rooted in the marked-based learning theory. The two approaches are conceptualized and operationalized on the basis of their differences along three processes: generation, dissemination and use of market information. In the retrospective approach, the generation process is based on expressed customer needs and extant market relations; the dissemination is based on formal mechanisms; the use process is more instrumental. In the forward-looking approach, the generation process is based on latent customer needs and on the evolutionary patterns of the future market relations; the dissemination process is more informal; the use of information is more conceptual. A series of hypotheses concerning the relationships between these approaches, product innovativeness and firm performance are tested on a sample of Italian fashion firms. Results suggest that the two approaches are complementary for firm performance, but have opposite effects on product innovativeness: while a forward-looking approach is positively related to product innovativeness, a retrospective approach seems to be negatively related. The results also shed light on how market information approaches and product innovativeness jointly affect firm performance.  相似文献   

Parental satisfaction with disabled children’s school inclusion in Italy     

Mirella Zanobini  Paola Viterbori  Valentina Garello  Roberta Camba 《欧洲特需教育杂志》2018,33(5):597-614

The principal aim of the present study is to examine the level of parental satisfaction with inclusive education for their children with disability attending Italian schools of any grade level. The survey involved 285 parents of pupils randomly selected from the population of students with disability certificates. On average, parents expressed a high level of satisfaction. Four principal components of parental satisfaction were extracted from the item scores of the questionnaire: inclusive educational practices; environment and special equipment; classmates’ and families’ acceptance; integration between education and rehabilitation activities. Various correlations were found between these aspects and both child-related and context-related variables. In particular, children’s emotional regulation abilities evaluated by teachers are involved in various dimensions of the parents’ satisfaction. On the other hand, satisfaction with the integration between the educational and rehabilitation activities showed a significant negative correlation with the fathers’ and mothers’ educational level. Lastly, parental satisfaction towards classmates’ and families’ acceptance appears to be the most critical aspect and tends to decrease in relation to school level, while it is positively linked with the number of hours the support teacher spends in class. Taken together, these results stimulate useful considerations to promote better practices in inclusive education.  相似文献   

Does it matter where patent citations come from? Inventor vs. examiner citations in European patents     

Paola Criscuolo 《Research Policy》2008,37(10):1892-1908

This paper addresses the question of whether patent citations are useful indicators of technology flows. We exploit the distinction between citations added by inventors and patent examiners. We use information from the search reports of European Patent Office patent examiners to construct our dataset of patenting activity in Europe and the US, and apply various econometric models to investigate what determines the probability that a citation is added by the inventor rather than the examiner. Contrary to previous work which uses US Patent and Trademark Office data, we find that geographical distance is a factor that strongly diminishes the probability of knowledge flows. We find other significant effects of such factors as cognitive distance, time and strategic factors on citing behaviour.  相似文献   

Mechanical power,thrust power and propelling efficiency: relationships with elite sprint swimming performance     

Giorgio Gatta  Ian Swaine  Paola Zamparo 《Journal of sports sciences》2018,36(5):506-512

The purpose of this study was to explore the relationships between mechanical power, thrust power, propelling efficiency and sprint performance in elite swimmers. Mechanical power was measured in 12 elite sprint male swimmers: (1) in the laboratory, by using a whole-body swimming ergometer (W'_TOT) and (2) in the pool, by measuring full tethered swimming force (F_T) and maximal swimming velocity (V_max): W'_T = F_T · V_max. Propelling efficiency (η_P) was estimated based on the “paddle wheel model” at V_max. V_max was 2.17 ± 0.06 m · s^?1, η_P was 0.39 ± 0.02, W'_T was 374 ± 62 W and W'_TOT was 941 ± 92 W. V_max was better related to W'_T (useful power output: R = 0.943, P < 0.001) than to W'_TOT (total power output: R = 0.744, P < 0.01) and this confirms the use of the full tethered test as a valid test to assess power propulsion in sprinters and to estimate swimming performance. The ratio W'_T/W'_TOT (0.40 ± 0.04) represents the fraction of total mechanical power that can be utilised in water (e.g., η_P) and was indeed the same as that estimated based on the “paddle wheel model”; this supports the use of this model to estimate η_P in swimming.  相似文献
