Pectin concentration, Molecular Weight and Degree of Esterification : Influence on Volatile Composition and Sensory Characteristics of Strawberry Jam
1991
Composition of headspace, consistency, taste and flavor characteristics were determined in jams made with different pectins. At usual concentrations, high methoxylated pectin induced an undesirable modification of typical flavor and intensity of flavor and taste, whereas low methoxylated pectin induced few alterations. At fixed concentration and molecular weight, a decrease in degree of esterification produced a significant decrease in consistency and noticeable modifications of the flavor perception and headspace composition, but no taste alteration. Mechanical reduction of pectin molecular weight significantly modified only the consistency.
Perceived minerality in sauvignon blanc wine: chemical reality or cultural construct?
2016
International audience; The study aimed to determine the relationship between perceived mineral character in wine and wine chemical composition. We investigated the sensory properties and chemical composition of sauvignon blanc wines from two major sauvignon-producing countries, New Zealand and France. Sensory experiments employing 16 wines (8 French, 8 New Zealand) were conducted in Marlborough, New Zealand and in three regions of France, namely Bordeaux, Burgundy, and the Sancerre/Loire region. Wine professionals (31 New Zealanders and 32 French professionals) sensorially characterised the 16 wines under three conditions, bouquet only (ortho-nasal olfaction), palate only (nose clip condit…
The Moderating Role of Performance in the Link From Interactional Justice Climate to Mutual Trust Between Managers and Team Members.
2016
The main goal of this study was to examine the interaction between team members’ performance and interactional justice climate in predicting mutual trust between managers and team members. A total of 93 small centers devoted to the attention of people with intellectual disability participated in the study. In each center, the manager ( N = 93) and a group of team members ( N = 746) were surveyed. On average, team members were 36.2 years old ( SD = 9.3), whereas managers were 41.2 years old ( SD = 8.8). The interaction between interactional justice climate and performance was statistically significant. Team members’ performance strengthened the link from interactional justice climate to mut…
Can High Group Cohesion Be Harmful?
2009
High group cohesion is considered to be beneficial and lead to better performance. This qualitative case study describes a case in which high social cohesion led to a deterioration in a team's performance. The aim of the present study was to investigate the relationships between performance in a team sport and social psychological group phenomena such as cohesion, conformity, groupthink, and group polarization. The participants were members of a junior-league ice-hockey team, consisting of three adult coaches and 22 players aged 15 to 16 years. The data were derived from an interview with the main coach, continuous observation by the principal researcher, and a diary based on observations …
Empowering team leadership and safety performance in nuclear power plants: A multilevel approach
2013
Abstract Despite the large body of work on team leadership, hardly any literature has dealt with team leadership in safety performance settings. The goal of the present study is to analyze how team leader behaviors influence team members’ safety performance in nuclear power plants. For this purpose, an empowering leadership approach was assessed. We consider a multilevel model in which safety performance is divided into three types of behaviors. The sample was composed of 479 workers in 54 groups from two Spanish nuclear power plants. The results suggested that leaders’ empowering behaviors generated higher safety compliance behaviors and higher safety participation behaviors by team member…
A person-environment-fit-model for temporary organizations - Antecedents for temporary working settings
2021
Abstract Projectification has led to the widespread use of temporary organizations (TOs) in many industries, but the various factors that determine successful work by employees in TOs are unexplored. We argue that organizations have different degrees of temporariness depending on the following five TO dimensions: temporal duration, nature of the task, team composition, hierarchy, and coordination. Considering the TO dimensions and varying degrees of temporariness, we propose a person-environment (P-E) fit model. The model comprises three levels – organizational-, group-, and job-oriented – and relates personal attributes to the TO dimensions. We contribute to theory by developing a set of p…
How team feedback and team trust influence information processing and learning in virtual teams: A moderated mediation model
2015
We study how team feedback influences information processing and learning in virtual teams.Group information is positively related to team learning in virtual teams.The indirect effect of team feedback on team learning via group information elaboration is moderated by team trust. This study examines a moderated mediation model in which team trust moderates the indirect effect of team feedback on team learning through group information elaboration in virtual teams. An experimental study in a laboratory was conducted with 54 teams randomly assigned to a team feedback condition or a control condition. Results provided empirical support to the moderated mediation model. We found that the indire…
The effects of virtuality level on task-related collaborative behaviors: The mediating role of team trust
2013
This study aims to analyze the mediating role of team trust in the relationship between virtuality level and task-related collaborative behaviors. Three types of task-related collaborative behaviors were studied, namely team coordination, team cooperation, and team information exchange. Drawing upon theory and research on virtual teams and trust, we hypothesized that team trust partially mediated the effects of virtuality level on team coordination, team cooperation, and team information exchange. A laboratory experiment was carried out with 65 four-person teams randomly assigned to three communication media with different virtuality levels (face-to-face, video conference and computer-media…
Interdependence between best team members and their teammates
2013
PurposeThe purpose of this paper is to examine how, within a team, the value of their best member depends critically on the performance of the rest. Analysis of the interdependent team members complements the traditional focus of resource‐based‐view analyses of isolated resources.Design/methodology/approachThe authors used data from 584 National Basketball Association teams (30 teams collected over 21 seasons).FindingsThe authors find a positive relationship between best member performance and team performance that increases as the rest of the team members’ performance improves.Practical implicationsHaving team members with a high individual performance does not imply that the team will hav…
Testing relations between group cohesion and satisfaction in project teams: A cross-level and cross-lagged approach
2014
Based on a two-dimensional perspective of group cohesion, this study examines the emergence of task cohesion and interpersonal cohesion in project teams and their roles in changes in members’ individual satisfaction with the team. Specifically, we tested a direct-effect and mediation model of the cross-level relationship between team task and interpersonal cohesion and individual satisfaction with the team over time. With a sample of 74 newly created project teams, the hypotheses were tested using a two-wave panel design. Results indicate that task cohesion emerges more strongly than interpersonal cohesion during the first stages of work in project teams. Moreover, the cross-lagged relation…
