Foam rolling is thought to improve muscular performance and flexibility as well as to alleviate muscle fatigue and soreness. For this reason, foam rolling has become a popular intervention in all kinds of sport settings used to increase the efficiency of training or competition preparation as well as to speed post-exercise recovery. The objective of this meta-analysis was to compare the effects of foam rolling applied before (pre-rolling as a warm-up activity) and after (post-rolling as a recovery strategy) exercise on sprint, jump, and strength performance as well as on flexibility and muscle pain outcomes and to identify whether self-massage with a foam roller or a roller massager is more…

Generation of TCR-engineered reference cell samples to control T-cell assay performance

2020

In vitro cellular assays analyzing antigen-specific T cells are characterized by their high complexity and require controlled conditions to lower experimental variations. Without standard cellular reagents, it is difficult to compare results over time and across institutions. To overcome this problem, a simple and robust technology was developed to generate TCR-engineered reference samples (TERS) containing defined numbers of antigen-specific T cells. Utilization of TERS enables performance control of three main T-cell assays: MHC-peptide multimer staining, IFN-gamma ELISpot and cytokine flow cytometry. TERS continuously deliver stable results and can be stored for longer periods of time. H…

An exploration of digital ride-hailing multisided platforms' market dynamics: empirical evidence from the Uber case study

2020

PurposeThe purpose of this paper is to experiment a dynamic performance management (DPM) approach to explore and assess the business dynamics of digital ride-hailing platforms with a focus on both supply and demand sides, and related interplays.Design/methodology/approachThe research adopts the DPM framework supported by simulation-based experimentations for developing a systemic case interpretation of Uber Inc. and its specific business complexity.FindingsThe emerging scenario analysis reveals that changes in the commission percentage for drivers and cutting prices for customers (car hailers) by competitors have significant impacts on the car-hailing industry.Originality/valueDPM and assoc…

The MAM-CAP table: A new tool for monitoring panel performances

2014

Abstract Assessor performances in sensory analysis are usually represented by three indicators: repeatability, discrimination and agreement. However, assessors can also differ on the range of their scores, the so-called “scaling effect”. Brockhoff, Schlich, and Skovgaard (2013) proposed the mixed assessor model (MAM) which, as the original assessor model ( Brockhoff & Skovgaard, 1994 ), takes this effect into account, but also allows for the product effect to be tested against a new interaction free of the scaling effect. The present paper proposes a unified system for monitoring assessor and panel performances based on the MAM. In addition to the product effect (tested at panel and individ…

Effects of a home-based rehabilitation program in community-dwelling older people after discharge from hospital: A subgroup analysis of a randomized …

2021

Objective: To examine whether pre-admission community mobility explains the effects of a rehabilitation program on physical performance and activity in older adults recently discharged from hospital. Design: A secondary analysis of a randomized controlled trial. Setting: Home and community. Participants: Community-dwelling adults aged ⩾60 years recovering from a lower limb or back injury, surgery or other disorder who were randomized to a rehabilitation ( n = 59) or standard care control ( n = 58) group. They were further classified into subgroups that were not planned a priori: (1) mild, (2) moderate, or (3) severe pre-admission restrictions in community mobility. Interventions: The 6-mont…

Les managers de proximité face aux compétences : une approche située

2013

Line managers and qualifications: a situated approachQualifications have seldom been analyzed as closely as possible to the operational level, a possibility of special interest to line managers and a genuine issue for research and management. Supervisors are continually in the position of making judgments about the qualifications of the persons and work teams whose activities they organize to reach the objectives set. Starting from observations conducted in several situations at the workplace, the concept of a “qualification oriented toward the situation” is drawn up around three dimensions : situation, qualification and performance. Its usefulness is empirically illustrated in the case of …

Further Evidence for Criterion Validity and Measurement Invariance of the Luxembourg Workplace Mobbing Scale

2020

Abstract. Workplace mobbing has various negative consequences for targeted individuals and are costly to organizations. At present it is debated whether gender, age, or occupation are potential risk factors. However, empirical data remain inconclusive as measures of workplace mobbing so far lack of measurement invariance (MI) testing – a prerequisite for meaningful manifest between-group comparisons. To close this research gap, the present study sought to further elucidate MI of the recently developed brief Luxembourg Workplace Mobbing Scale (LWMS; Steffgen, Sischka, Schmidt, Kohl, & Happ, 2016 ) across gender, age, and occupational groups and to test whether these factors represent im…

A Grounded Theory of Elite Male Table Tennis Players’ Activity during Matches

2006

International audience; This article describes the main features of a collaborative project involving researchers, coaches, and elite table tennis players. The project was carried out between 1997 and 2002 with funding from the French Ministry of Youth and Sports, in response to a request by French Table Tennis Team coaches to improve the training of table tennis players. Matches were videotaped during international meets and followed by interviews during which the players described and commented on their activity as they viewed the tapes. A grounded theory of players' activity emerged from the data collected and the ensuing theoretical issues that were raised. The findings on table tennis …

Analyse historique du concept de performance en Chine. Un regard occidental

2015

A historical analysis of the concept of Performance in China. A Western lectureWe base our work on an historical study of the concept of performance in China. We postulate from a literature review that organizations and their managers are strongly influenced by cultural and institutional determinants. As a result, we present these determinants that enable us to justify several hypotheses about Chinese managers’ behaviors. In this article, we show the disappearance of Confucian values behind a combination of pragmatism, interpersonal relations and influence networks.

On the participatory agency of texts: Using institutional forms in performance appraisal interviews

2020

Abstract Drawing on studies of the performative effects and agency of texts in organizations, the paper investigates how the agency of texts figures through their participatory status in interaction. The empirical data for the study consist of video-recorded performance appraisal interviews in a Finnish public organization in which the interaction relies heavily on an appraisal form. The data are analyzed through a sequential analysis that draws on multimodal conversation analysis and ethnographic knowledge. The analysis shows that the human participants orient to three different acts that are inscribed in the textual document: 1) presenting demands for the participants; 2) offering topics …
