Objective Postoperative rehabilitation protocols, such as immobilization and non-weight-bearing periods during the acute phase after anterior cruciate ligament (ACL) surgery vary depending on the surgeon or the institution and lack clear standardization. Weight bearing (WB) after ACL reconstruction (ACLR) is critical. This study compares the results of WB immediately after surgery and partial WB with a brace after ACLR. Materials & Methods In this randomized clinical trial, the block random sampling method was used to select 84 patients who were divided into two groups. Group 1 was allowed to have full WB after surgery and Group 2 was asked to use braces after surgery, and they were divided into partial WB for one month and then full WB. Meanwhile, demographic information was recorded. The Lachman test, anterior knee pain, and kneeling pain before and one month after the surgery were also recorded. Knee function was evaluated using the international knee documentation committee, knee injury and osteoarthritis out-come score, and Lysholm scales before surgery and 1, 3, and 6 months after surgery. The data were analyzed using the SPSS software, version 20, and the Fisher exact test, the chi-square test, the Friedman test, and repeated measures analysis of variance. Results Most of the patients were men under 30 years of age. There was no statistically significant difference in the demographic information of the patients in the two groups. Kneeling pain, anterior knee pain, and the Lachman test did not differ between the two groups one month after the surgery. There was no difference between the two groups in the scores using the international knee documentation committee, knee injury and osteoarthritis outcome score, and Lysholm score in the 6-month follow-up. All the examined indicators in each group improved over time. Conclusion WB immediately after surgery compared to partial WB at 1, 3, and 6 months after ACLR do not differ; therefore, patients can bear full weight if they tolerate it. [ABSTRACT FROM AUTHOR]

This paper investigates the short-term price predictability of US equity Exchange Trade Funds (ETFs) in reaction to one-day extreme returns. We also assess the cross-section features associated to price overreaction following extreme price movements. The literature on the short-term overreaction of ETFs is rather scarce. Furthermore, existing studies tend to focus on delimited historical periods, which makes their results difficult to generalize. Our paper fills this gap by considering a comprehensive sample of ETFs over an extended period of time. In addition, we are the first to study the effect of the prevailing market trend and of liquidity on the patterns of overreaction and subsequent price reversal of ETFs. Being the major ETFs the most actively traded equity securities on the US stock exchanges, their performance and characteristics are of interest by themselves. Our findings suggest that market regulators should concentrate their resources on overseeing the ETF pricing that occurs after-hours. For market practitioners, our results indicate the existence of profitable market opportunities after large price movements. In the present study, we tested the significance of the mean returns for the period immediately after extreme returns. We also conducted a multivariate analysis where the price reversal was regressed against the cross section features of the ETFs under study. We contribute to the literature on ETF price formation as we document, for the first time, the existence of a stark contrast in the reaction to extreme price movements in these assets during normal hours and afterhours periods. On average, the extreme returns that occur in the after-hours period represent an overreaction, leading to a price reversal in the following period. In addition, we show that both tax-motivated trading and noise trading play a role in the pattern of ETF overreaction and reversal. [ABSTRACT FROM AUTHOR]

This article aims to broaden understanding of the phenomenon of legitimacy of civil society organizations (CSOs), interpreting it in the light of the critical capacity theory, proposed by Boltanski and Thévenot (2006). More specifically, it identifies, by means of discourse analysis of representative actors from the field, which are the justifications supporting the action and existence of CSOs, providing them with legitimacy. Having as a basis the theoretical framework and an analysis of the trajectory of the field in Brazil, some hypotheses were formulated: 1) that several reasonings are used in the justifications; 2) that the meeting between these reasonings provokes disputes and conflicts; 3) that it enables constructing footbridges; and 4) that there are predominant reasonings isolating the existence of other ones. Through discourse content analysis of 46 representative actors of the field of CSOs in the Brazilian South region, the hypotheses were tested and we found out that the predominant legitimacy dimensions in these CSOs are the pragmatic and moral, which stimulate the adaptation of CSOs to externally set standards, making plurality and, thus, democracy in the field weaker.

Several surveys on Information Science recurrently indicate the existence of a new field of study in economics, named information economy. According to the information impact perspective, observed along with activation procedures of organization development, from the performance, expansion, penetration and consolidation point of view on the referred market, enhancing information as a market product affects the criterion analysis sine qua non of its research procedures and use. This study corroborates the hypothesis that these studies enable enlightenment on which information flow leads company managers to appropriate and constructed knowledge. Therefore, reflecting and understanding on how knowledge is constructed entails the main object of current study and specifically, considering the manager work context and the changing nature of organizations, how information use impacts on knowledge construction. From a methodological perspective, it is featured as a longitudinal and contextual study, analyzed regarding the evaluation model of information activity. The study has focused its action on a plastics company located at State of Pernambuco, Brazil. The research noticed that the results of informational impact can evaluate the information use and its effect on decision taking, characterizing the informational process legitimacy; however the phenomenon must not be studied apart from its historical and organizational context.
