Efficience des joueurs dans la ligue nationale de hockey.

En l’absence de mesure précise et unique de l’efficience pour les joueurs de hockey, la présente étude a pour objectifs d’évaluer l’efficience des joueurs dans la Ligue Nationale de Hockey (LNH) et de montrer comment celle-ci peut affecter la décision de racheter le contrat d’un joueur. Pour ce faire, les statistiques individuelles des joueurs de la LNH pour les saisons 2007-2008 à 2010-2011 sont utilisées. Pour estimer l’efficience, la méthode de l’enveloppement de données (DEA) avec bootstrap est utilisée. Les inputs incluent le salaire et le nombre de minutes de jeu, alors que les outputs incluent la contribution défensive et offensive de chaque joueur. Pour estimer l’association entre l’efficience individuelle et la probabilité d’un rachat de contrat, une régression logistique est utilisée. L’analyse des données montre que parmi 3 159 observations, l’efficience moyenne est de 0,635. L’efficience moyenne est similaire pour toutes les positions et toutes les saisons. Un lien positif et fort est trouvé entre le nombre de points au classement général d’une équipe et l’efficience moyenne des joueurs qui la compose (coefficient de corrélation=0,43, valeur-p<0,01). Les joueurs avec une efficience plus élevée ont une probabilité plus faible de voir leur contrat racheté (rapport des chances=0,01, valeur-p<0,01). La présente étude conclut donc que la plupart des joueurs de hockey dans la LNH ont un degré d’inefficience non négligeable, qu’une efficience plus élevée est associée à une meilleure performance au niveau de l’équipe et que les joueurs efficients ont une probabilité plus faible de voir leur contrat racheté

Evaluation Factors for Multi-Stakeholder Broadband Visual Communication Projects

This paper presents a summary of multifaceted evaluation factors that we have identified through our research with Broadband Visual Communication (BVC) projects involving multiple stakeholders. The main benefit of these evaluation factors is that they provide a general evaluation framework for multiple stakeholder projects. The factors are social infrastructure, technical infrastructure, physical space, interaction style and content

Real-world utilization and outcomes of systemic therapy among patients with advanced or recurrent endometrial cancer in the United States

OBJECTIVE: Evaluate systemic therapy utilization patterns and outcomes by line of therapy among patients with advanced/recurrent endometrial cancer (EC) treated in the United States. METHODS: This retrospective observational study used the Optum Clinformatics Extended Data Mart Date of Death database (1 January 2004-31 December 2019) and included de-identified data from adult patients with advanced/recurrent EC who were treated with first-line (1L) platinum-based chemotherapy and initiated second-line (2L) anti-neoplastic therapy. The index date was the date of 1L therapy initiation. The number and sequence of treatments received and the proportion of patients who received each type of treatment for each line of therapy were evaluated. To account for new drug approvals, patients first treated in 2018 or 2019 were also assessed separately. RESULTS: Among the 1317 patients who met all eligibility criteria, 520 (39.5%) and 235 (17.8%) patients received 3 or 4+ lines of treatment, respectively, during a median total follow-up time of 25.2 months (range, 2.5-173.3 months) following the index date. Chemotherapy, including platinum- and non-platinum-based regimens, was the most common treatment across all lines of therapy: 2L, 80.0%; 3L, 66.2%; 4L+, 80.4%. Overall, 2.5%, 2.3%, and 8.9% of 2L, 3L, and 4L + patients, respectively, received anti-program death 1 (anti-PD-1) immunotherapies. In patients first treated in 2018 and 2019 ( CONCLUSIONS: Among patients with advanced/recurrent EC treated with 1L platinum-based therapy in clinical practice, chemotherapy was the most common treatment choice across all lines of therapy. Immunotherapy use was low overall but increased in patients who started treatment in 2018 or 2019. Overall, median TTNT decreased as lines of therapy increased

Human Capacity Development Through Simulations: Constructive Simulations as a Basis for Competency Requirements and Training

ABSTRACT: This paper presents the state of development of a constructive simulation to better understand competency requirements in initiative based tactics in order to support training scenario design in a virtual training environment. The simulations of interest are cognitive models. The first section situates the development functions of understanding, training, and assisting human capabilities, in relationship to the traditional distinction of live, virtual and constructive simulations. The human development and their associated simulation types can also be laid out on a continuum of agent embedment in physical settings. The second section presents relevant cognitive modeling and simulated environment elements required by initiative based tactics; as well as some initial requirements for training scenario design. A conclusion summarizes the paper and indicates some future work possibilities
