The Great Books in Criminal Justice: As Ranked by Elite Members of the Academy of Criminal Justice Sciences     

Gennaro F. Vito  Richard Tewksbury 《Journal of Criminal Justice Education》2013,24(3):366-382

Attempts to define the core body of knowledge in criminal justice have provided diverse and disparate explanations of what could be considered as central to the discipline. Previous efforts have focused on frequently cited authors and works, required learning for students and the personal beliefs of individual scholars. The present work adds to this body by examining the works considered by an elite sample of criminal justice educators as classics in the field. Based on a survey of Academy of Criminal Justice Sciences Presidents, Fellows and Bruce Smith Award winners the classic books in criminal justice are identified. Results show that a wide range of works and authors is identified, with relatively little consensus either across the sample or with previously identified works and authors. Comparison of presently identified works with those frequently cited and commonly required for doctoral students shows that only a minority of works identified by others are also considered classics by our elite sample.  相似文献

Abstract

Kinematic analysis of swimming is of interest to improve swimming performances. Although the video recordings of underwater swimmers are commonly used, the available methodologies are rarely precise enough to adequately estimate the three dimensional (3D) joint kinematics. This is mainly due to difficulties in obtaining the required kinematic parameters (anatomical landmarks, joint centres and reference frames) in the swimming environment. In this paper we propose a procedure to investigate the right upper limb’s 3D kinematics during front crawl swimming in terms of all elbow and shoulder degrees of freedom (three rotations of the shoulder, two of the elbow). The method is based upon the Calibrated Anatomical Systems Technique (CAST), a technique widely used in clinics, which allows estimation of anatomical landmarks of interest even when they are not directly visible. An automatic tracking technique was adopted. The intra-operator repeatability of the manual tracking was also assessed. The root mean squared difference of three anatomical landmarks, processed five times, is always lower than 8 mm. The mean of the root mean squared difference between trajectories obtained with the different methodologies was found to be lower than 20 mm. Results showed that complete 3D kinematics of at least twice as many frames than without CAST can be reconstructed faster and more precisely.  相似文献   

Evaluating subtopic retrieval methods: Clustering versus diversification of search results     

Claudio Carpineto  Massimiliano D’AmicoGiovanni Romano 《Information processing & management》2012

To address the inability of current ranking systems to support subtopic retrieval, two main post-processing techniques of search results have been investigated: clustering and diversification. In this paper we present a comparative study of their performance, using a set of complementary evaluation measures that can be applied to both partitions and ranked lists, and two specialized test collections focusing on broad and ambiguous queries, respectively. The main finding of our experiments is that diversification of top hits is more useful for quick coverage of distinct subtopics whereas clustering is better for full retrieval of single subtopics, with a better balance in performance achieved through generating multiple subsets of diverse search results. We also found that there is little scope for improvement over the search engine baseline unless we are interested in strict full-subtopic retrieval, and that search results clustering methods do not perform well on queries with low divergence subtopics, mainly due to the difficulty of generating discriminative cluster labels.  相似文献   

From new imported inputs to new exported products. Firm-level evidence from Sweden   总被引：2，自引：0，他引：2  

Davide Castellani  Claudio Fassio 《Research Policy》2019,48(1):322-338

This paper investigates the determinants of the propensity of firms to export new products, and focuses on the role of new imported inputs. Importing offers access to new technologies and better combination of inputs that can lead to new or improved products for the export markets. Based on a sample of more than 14,000 Swedish manufacturing firms over the period 2001–2012, we show that importing new inputs is a key determinant of firms’ propensity to add new products to their export portfolio, even after controlling for multinationality, patenting activity, productivity and a number of other firm characteristics. This is mainly due to the import of new intermediate inputs and it is stronger for smaller firms.  相似文献   

Skilled migration and innovation in European industries     

Claudio Fassio  Fabio Montobbio  Alessandra Venturini 《Research Policy》2019,48(3):706-718

This paper studies the effects of skilled migration on innovation –proxied by patent citations- in European industries between 1994 and 2005, using the French and the UK Labour Force Surveys and the German Microcensus. Highly-educated migrants have a positive effect on innovation, but the effect differs across industries. It is stronger in industries with low levels of overeducation, high levels of FDIs and openness to trade and, finally, in industries with higher ethnic diversity. The aggregate effect of the skilled immigrant is about one third the one of the skilled natives. We tackle the endogeneity of migrants with a set of external and internal instruments.  相似文献   

The process toward commitment to running—The role of different motives,involvement, and coaching     

Claudio M. Rocha  Otavio A. Gratao 《Sport Management Review》2018,21(4):459-472

The purpose of this investigation was twofold: (a) to explore and describe the relationships between different facets of motivation, involvement, and commitment to running, and (b) to test whether recreational coached runners differ from non-coached runners in their motivation, involvement, and commitment to running. Drawing on the psychological continuum model (PCM), a model was proposed to test relationships among motives, attitudinal and behavioral involvement, and commitment to running as a leisure activity. Results showed that two (enjoyment and health) out of five motives were significant indicators of attitudinal involvement. Attitudinal involvement was a significant predictor of behavioral involvement, which in turn was a significant predictor of commitment. Coached runners differed from non-coached runners in all tested variables. The structural relationships among the variables varied based on the tested group. Implications for theory and practice are presented.  相似文献   

Physiological intensity profile,exercise load and performance predictors of a 65-km mountain ultra-marathon     

Alessandro Fornasiero  Aldo Savoldelli  Damiano Fruet  Gennaro Boccia  Barbara Pellegrini  Federico Schena 《Journal of sports sciences》2018,36(11):1287-1295

The aims of the study were to describe the physiological profile of a 65-km (4000-m cumulative elevation gain) running mountain ultra-marathon (MUM) and to identify predictors of MUM performance. Twenty-three amateur trail-runners performed anthropometric evaluations and an uphill graded exercise test (GXT) for VO_2max, ventilatory thresholds (VTs), power outputs (PMax, PVTs) and heart rate response (HRmax, HR@VTs). Heart rate (HR) was monitored during the race and intensity was expressed as: Zone I (VT2) for exercise load calculation (training impulse, TRIMP). Mean race intensity was 77.1%±4.4% of HRmax distributed as: 85.7%±19.4% Zone I, 13.9%±18.6% Zone II, 0.4%±0.9% Zone III. Exercise load was 766±110 TRIMP units. Race time (11.8±1.6h) was negatively correlated with VO_2max (r = ?0.66, P <0.001) and PMax (r = ?0.73, P <0.001), resulting these variables determinant in predicting MUM performance, whereas exercise thresholds did not improve performance prediction. Laboratory variables explained only 59% of race time variance, underlining the multi-factorial character of MUM performance. Our results support the idea that VT1 represents a boundary of tolerable intensity in this kind of events, where exercise load is extremely high. This information can be helpful in identifying optimal pacing strategies to complete such extremely demanding MUMs.  相似文献   

Asynchronous event-triggered observation and control of linear systems via impulsive observers     

L. Etienne  Y. Khaled  S.Di Gennaro  J.P. Barbot 《Journal of The Franklin Institute》2017,354(1):372-391

In this paper we investigate the observation and stabilization problems of a linear plant subject to network constraints and partial state knowledge, making use of the event-triggered technique. In order to address these problems, an impulsive observer is designed. Sufficient conditions are given to ensure a milder version of separation principle for linear systems controlled via an event-triggered controller. The proposed observer ensures practical state estimation, while the corresponding dynamic controller ensures practical stabilization. The sampling and the transmission of the output and the input are done asynchronously. The dynamic controller is tested in simulation on the linearized inverted pendulum.  相似文献   

A longitudinal study in learning preferences and academic performance in first year medical school          下载免费PDF全文

Yenya Hu  Hong Gao  Marcia M. Wofford  Claudio Violato 《Anatomical sciences education》2018,11(5):488-495

This is a longitudinal study of first year medical students that investigates the relationship between the pattern change of the learning preferences and academic performance. Using the visual, auditory, reading‐writing, and kinesthetic inventory at the beginning of the first and second year for the same class, it was found that within the first year, 36% of the class remained unimodal (single) modality learners (SS), 14% changed from unimodal to multimodality learners (SM), 27% changed from multimodality to unimodal modality learners (MS) and 21% remained as multimodality learners (MM). Among the academic performance through subsequent didactic blocks from Clinical Anatomy, Cell and Subcellular Processes to Medical Neuroscience during first year, the SM group made more significant improvement compared to the SS group. Semi‐structured interview results from the SM group showed that students made this transition between the Clinical Anatomy course and the middle of the Medical Neuroscience course, in an effort to improve their performance. This study suggests that the transition from unimodal to multimodality learning among academically struggling students improved their academic performance in the first year of medical school. Therefore, this may be considered as part of academic advising tools for struggling students to improve their academic performances.

University students’ conceptions of learning across multiple domains     

Claudio Vezzani  Giulia Vettori  Giuliana Pinto 《European Journal of Psychology of Education - EJPE》2018,33(4):665-684

Research on students’ conceptions of learning is a growing and complex area of interest in the field of psychology of education. Even though much of the investigation addressed to explore conceptions of learning at the university level, still less research has considered how naïve (i.e. ‘learning as reduction of deficit knowledge through individual effort’) and sophisticated (i.e. ‘learning as opportunity and self-efficacy’) conceptions of learning are related to personal and contextual factors. This research investigated how gender, academic area, and level of study influence university students’ conceptions of learning. Three hundred forty-six university students participated in the study. They were either from humanities (240) or technical-scientific (106) areas of study and they were attending either a Bachelor (140) or Master’s degree (206) course. Conceptions of learning were explored using a self-report instrument (Learning Conceptions Questionnaire; LCQ). A MANOVA revealed that females show conceptions of learning more related to social and motivational aspects of learning with a greater personal involvement, compared with males. No typical pattern of conceptions of learning was found for humanities students or for technical-scientific students. Increasing with the level of study, students showed both naïve and sophisticated conceptions of learning increased, since both ‘learning as reduction of deficit knowledge through individual effort’ and ‘learning as opportunities and self-efficacy’ were more likely. Implications of these results and future lines of research will be discussed.  相似文献
