Institutions make new forms of acting possible: Signing executive orders, scoring goals, and officiating weddings are only possible because of the U.S. government, the rules of soccer, and the institution of marriage. Thus, when an individual occupies a particular social role (President, soccer player, and officiator) they acquire new ways of acting on the world. The present studies investigated children’s beliefs about institutional actions, and in particular whether children understand that individuals can only perform institutional actions when their community recognizes them as occupying the appropriate social role. Two studies (Study 1, N = 120 children, 4-11; Study 2, N = 90 children, 4-9) compared institutional actions to standard actions that do not depend on institutional recognition. In both studies, 4- to 5-year-old children believed all actions were possible regardless of whether an individual was recognized as occupying the social role. In contrast, 8- to 9-year-old children robustly distinguished between institutional and standard actions; they understood that institutional actions depend on collective recognition by a community.

Abstract Soccer is undeniably the most popular sport world-wide and everyone from general managers and coaching staff to fans and media are interested in evaluating players’ performance. Metrics applied successfully in other sports, such as the (adjusted) +/− that allows for division of credit among a basketball team’s players, exhibit several challenges when applied to soccer due to severe co-linearities. Recently, a number of player evaluation metrics have been developed utilizing optical tracking data, but they are based on proprietary data. In this work, our objective is to develop an open framework that can estimate the expected contribution of a soccer player to his team’s winning chances using publicly available data. In particular, using data from (i) approximately 20,000 games from 11 European leagues over eight seasons, and, (ii) player ratings from the FIFA video game, we estimate through a Skellam regression model the importance of every line (attackers, midfielders, defenders and goalkeeping) in winning a soccer game. We consequently translate the model to expected league points added above a replacement player (eLPAR). This model can further be used as a guide for allocating a team’s salary budget to players based on their expected contributions on the pitch. We showcase similar applications using annual salary data from the English Premier League and identify evidence that in our dataset the market appears to under-value defensive line players relative to goalkeepers.

Abstract Purpose To report our experience using endoscopic intranasal incision reduction (EIIR) for nasal fractures and to assess effectiveness of the method. Methods 30 patients who underwent EIIR were retrospectively analysed. All the patients were examined by three-dimensional computed tomography (3D CT), acoustic rhinometry and rhinomanometry, preoperatively and postoperatively at 1 month. The visual analogue scale (VAS) was used to assess the preoperative aesthetics and nasal airflow satisfaction and at 1, 3 and 6 months postoperatively. VAS aesthetic satisfaction was also scored by two junior doctors. Results 3D CT showed that the fracture fragments fitted well in 30 patients postoperatively at 1 month. VAS aesthetics and nasal airflow scores were significantly improved postoperatively at 1, 3 and 6 months compared with preoperative scores (P < 0.01). The VAS aesthetic scores from the two surgeons were also significantly improved (P < 0.01). The minimal cross-sectional area increased from 0.39 ± 0.13 to 0.64 ± 0.13 (P < 0.001), the nasal volume increased from 4.65 ± 0.86 to 6.37 ± 0.94 (P < 0.001) and the total inspiratory airway resistance of the bilateral nasal cavity median decreased from 0.467 Pa/mL/s to 0.193 Pa/mL/s (P < 0.001). There were no technique-related intraoperative complications. Conclusion EIIR was a practical choice, and the aesthetics and nasal airflow were significantly improved in patients with overlapped and displaced bone fragments, patients with fractures of the frontal process of the maxilla (FFPM), patients who underwent failed CR and patients beyond the optimal temporal window.

The incidence of medial sesamoid bone fracture is rare. Clinically they are often misdiagnosed as soft tissue injuries and often missed. Thus generates an important morbidity for the patient. Objectives: We present a case of turf-toe injury: plantar-plate rupture with medial sesamoid bone fracture in a contact athlete. Methods: A 19-year-old professional soccer player injured his left toe when he planted his foot during a sprint. He had an hyperextension and axial overload traumatism in his toe. On physical examination he had pain, swollen, ecchymosis, instability and loss of plantar-flexion strength. Radiographs showed a transverse medial sesamoid bone fracture with retraction > 3 mm. Magnetic resonance imaging confirmed a subluxation of the proximal phalange and a plantar plate disruption. Because of the completely deficient flexion, the sesamoid retraction, and the articular subluxation, surgery was recommended to restore the MTPJ anatomy. Reduction of the fracture and Repair of the plantar plate was performed using non-absorbable 2-0 Fiber wire sutures through a medial approach. Postoperatively, the patient was placed in a cast, for a total of 2 weeks. After that he began a rehabilitation program. Results: The patient had a complete recovery. He returned to participation in his team at 3 months. At final follow-up, his dorsiflexion ROM was 60 in the involved toe. Conclusion: Turf-toe and disorders of the sesamoid complex is an important injury, often misdiagnosed and usually undertreated. They had an incidence of 25% to 50% of residual pain and limited dorsiflexion in those cases. Despite the incidence of surgical treatment of 2%, we have found hopeful results with the open reduction and internal fixation of the fracture. Accurate and timely diagnosis and treatment can allow for full return to activity for these athletes.
