Aplicación de la terapia de modelado en la prevención del inicio al consumo de la droga     

Diego Macia 《Infancia y Aprendizaje》2013,36(26):87-94

Resumen

La presente investigación ha consistido en desarrollar un método preventivo del inicio al consumo de droga, por medio del aprendizaje observacional, destinado a adolescentes. Se pretendía modificar la actitud hacia la droga, así como dotar de habilidades comportamentales suficientes a los sujetos, con el fin de que pudieran hacer frente a determinadas situaciones, causa, en muchos casos, del inicio de la drogadicción.

La hipótesis principal era que un programa educativo, más modelado y la técnica de rol-playing, cambiará la actitud hacia la droga y facilitará el aprendizaje de comportamientos que ayuden a la prevención.

Los resultados indican un cambio de actitud hacia determinadas drogas y una actitud más favorable a la realización de determinados comportamientos que favorecerán la posibilidad de resistirse a la iniciación al consumo de la droga.  相似文献   

An Application of Generalizability Theory to Evaluate the Technical Quality of an Alternate Assessment     

Melinda Ann Taylor  Dena A. Pastor 《教育实用测度》2013,26(4):279-297

Although federal regulations require testing students with severe cognitive disabilities, there is little guidance regarding how technical quality should be established. It is known that challenges exist with documentation of the reliability of scores for alternate assessments. Typical measures of reliability do little in modeling multiple sources of error, which are characteristic of alternate assessments. Instead, Generalizability theory (G-theory) allows researchers to identify sources of error and analyze the relative contribution of each source. This study demonstrates an application of G-theory to examine reliability for an alternate assessment. A G-study with the facets rater type, assessment attempts, and tasks was examined to determine the relative contribution of each to observed score variance. Results were used to determine the reliability of scores. The assessment design was modified to examine how changes might impact reliability. As a final step, designs that were deemed satisfactory were evaluated regarding the feasibility of adapting them into a statewide standardized assessment and accountability program.  相似文献   

Fifteen years of action research as professional development: seeking more collaborative,useful and democratic systems for teachers   总被引：1，自引：1，他引：0  

Víctor M. López‐Pastor  Roberto Monjas  Juan Carlos Manrique 《Educational Action Research》2013,21(2):153-170

This paper presents the experience of a group of teachers who have developed action research (AR) dynamics for 15 years aimed at their professional development and teaching practice improvement. The focus is first on the importance of AR, collaborative dynamics and theory and practice relationships for in‐service teacher training. It also shows the different spiral and cycle stages carried out, as well as the group’s characteristics, its evolution during these 15 years and the annual operation structure currently in use. The results show the five large AR thematic spirals developed and the materials generated and disseminated. There is also an analysis of the main benefits and problems so far encountered. Finally, a series of reflections and conclusions on the implications of keeping such a workgroup for so long is detailed.  相似文献

Are patents signals for the IPO market? An EU–US comparison for the software industry     

Diego Useche 《Research Policy》2014

This study investigates empirically whether patents can be signals to financial markets, thus reducing problems of asymmetric information. In particular we study how patenting behaviour impacts on the way investors perceive software firms’ growth potential through an increase in the amount invested at the initial public offering (IPO) of firms in the US and Europe. This study performs regressions on the relationship of patent applications before IPO and the amount of money collected at the IPO, while controlling other factors that may influence IPO performance. We also attempt to account for a potential source of endogeneity problems that can arise for self-selection bias and simultaneity between the number of patent applications prior to going public and the amount of money collected at IPO. We find significant and robust positive correlations between patent applications and IPO performance. The signalling power of patenting is significantly different for US and European companies, and is related to the difficulty in obtaining a signal and its scarcity. An additional patent application prior to IPO increases IPO proceeds by about 0.507% and 1.13% for US and European companies, respectively. Results suggest that a less ‘applicant friendly’ patenting system increases the credibility of patents as signals and their value for IPO investors.  相似文献   

Effects of concurrent training on interleukin-6, tumour necrosis factor-alpha and C-reactive protein in middle-aged men   总被引：1，自引：1，他引：0  

Libardi CA  Souza GV  Gáspari AF  Dos Santos CF  Leite ST  Dias R  Frollini AB  Brunelli DT  Cavaglieri CR  Madruga VA  Chacon-Mikahil MP 《Journal of sports sciences》2011,29(14):1573-1581

The purpose of this study was to evaluate the effects of moderate- to high-intensity resistance and concurrent training on inflammatory biomarkers and functional capacity in sedentary middle-aged healthy men. Participants were selected on a random basis for resistance training (n = 12), concurrent training (n = 11) and a control group (n = 13). They performed three weekly sessions for 16 weeks (resistance training: 10 exercises with 3 × 8-10 repetition maximum; concurrent training: 6 exercises with 3 × 8-10 repetition maximum, followed by 30 minutes of walking or running at 55-85% [Vdot]O(2peak)). Maximal strength was tested in bench press and leg press. The peak oxygen uptake ([Vdot]O(2peak)) was measured by an incremental exercise test. Tumour necrosis factor-α, interleukin-6 and C-reactive protein were determined. The upper- and lower-body maximal strength increase for both resistance (+42.52%; +20.9%, respectively) and concurrent training (+28.35%; +21.5%, respectively) groups (P = 0.0001).[Vdot]O(2peak) increased in concurrent training when comparing pre- and post-training (P = 0.0001; +15.6%). No differences were found in tumour necrosis factor-α and interleukin-6 for both groups after the exercise. C-reactive protein increased in resistance training (P = 0.004). These findings demonstrated that 16 weeks of moderate- to high-intensity training could improve functional capacity, but did not decrease inflammatory biomarkers in middle-aged men.  相似文献   

Filipino Arts Among Elders in Institutionalized Care Settings     

Allan B. de Guzman  James Cyril B. Satuito  Miko Anne E. Satumba  Diego Rey A. Segui  Faith Evelyn C. Serquiña  Lawrence Jan P. Serrano 《Educational gerontology》2013,39(3):248-261

The use of traditional art in recreational therapies is unexplored. This paper, thus, attempts to surface the unique power of traditional Filipino arts (TFA) as synergizing lens in capturing the individual and the collective experiences of a select group of Filipino elderly in an institutionalized care setting relative to their feelings of depression and self-esteem. Three Filipino elderly housed in an institutionalized care setting were chosen for this phenomenological study, a robotfoto and a series of semistructured interviews constitute the main data gathering tool. Field texts were subjected to phenomenological reduction via the repertory grid analysis. Emerged themes were subjected to a series of member checking procedures to ensure the trustworthiness of the reported data. Depression and self-esteem were interpreted via two emerged themes. The themes were Me, Myself, and Melancholy and Will Not Let My Worth Wither. Through recreational therapies in the form of traditional Filipino arts, participants found novel psychological crutches that overcame the challenges of depression and give them hope toward more positive views of themselves and life.  相似文献

Pigments and binders in “Madonna col Bambino e S. Giovannino” by Botticelli investigated by micro-Raman and GC/MS     

Danilo Bersani  Pier Paolo Lottici  Antonella Casoli  Diego Cauzzi 《Journal of Cultural Heritage》2008,9(1):97-102

During the restoration plan of the famous painting “Madonna col Bambino e S. Giovannino” by Sandro Botticelli, located in the Museo Civico of Piacenza (Italy), a study on painting materials was carried out. The pigments, the binders and the materials used for the application of ground and priming layers were studied using micro-Raman spectroscopy, gas chromatography coupled with mass spectrometry (GC/MS), optical and electronic microscopies. Gypsum and anhydrite were found in the ground layer, while carbon black and lead white were used in the priming layers. The precious pigments of the artist's palette and the binders used (egg and animal glue) were determined.  相似文献   

Validity and reliability of rating perceived exertion in women with fibromyalgia: exertion-pain discrimination     

Alberto Soriano-Maldonado  Jonatan R. Ruiz  Inmaculada C. Álvarez-Gallardo  Víctor Segura-Jiménez  Alfredo Santalla  Diego Munguía-Izquierdo 《Journal of sports sciences》2015,33(14):1515-1522

The present study aimed (1) to assess the validity and reliability of the Borg category-ratio (CR-10) scale for monitoring exercise intensity in women with fibromyalgia (FM) and (2) to examine whether women with FM can discriminate between perceived exertion and exercise-induced pain. Thirty-three women with FM performed two incremental treadmill tests (1 week separated). Heart rate, oxygen uptake, minute ventilation and respiratory quotient were measured. The ratings of perceived exertion (RPE: CR-10 scale) and exercise-induced pain were obtained at each workload. The Spearman’s correlation of RPE with the physiological responses ranged from 0.69 to 0.79. The regression models explained ~50% of the variability of the studied physiological responses. We found “perfect acceptable” agreement in 69% of the observations. Weighted Kappa was 0.66 (95% confidence interval [CI]: 0.59–0.72). There were differences between RPE and pain at workloads 3 (1.50; 95%CI: 0.85–2.16), 4 (2.10; 95%CI: 1.23–2.96), 5 (3.40; 95%CI: 1.29–5.51) and 6 (3.97; 95%CI: 1.61–6.33). The main findings of the present study suggest that the Borg CR-10 scale is valid and moderately reliable for monitoring exercise intensity in women with FM, and these patients were able to discriminate between exertion and exercise-induced pain.  相似文献
