Team adaptability and task cohesion as resources to the non-linear dynamics of workload and sickness absenteeism in firefighter teams

ABSTRACT

The current study builds on the non-linear Dynamic Systems (NDS) perspective to test the assumption that change in sickness absenteeism is non-linear, and that such change is due to workload, team adaptability and task cohesion. Participants were 37 firefighter teams (n = 250 individuals) from a main European capital city. The research hypotheses were tested using SPSS and the “cusp” package, in the statistical software R. The results suggest that change in sickness absenteeism behaviours over time is non-linear, with the cusp catastrophe model predicting such behaviours better than the linear and logistic models. In our model, task cohesion functions as an asymmetry factor (i.e., the independent variable that determines the strength and discrepancy between the two stable states of the dependent variable) leading to a linear change in sickness absenteeism. Interestingly, both workload and team adaptability function as bifurcation (i.e., the independent variable that determines the change between the two stable states of the order parameter) and asymmetry factors leading to non-linear and linear change in sickness absenteeism over time. This study contributes to the growing evidence that incorporating the NDS perspective enables a better understanding of action teams, namely those working in extreme environments.     

Psychometric properties of the Portuguese version of the Alabama Parenting Questionnaire parent form

ABSTRACT

The Alabama Parenting Questionnaire parent form (APQ-P) is one of the most commonly used measures to assess parenting practices. The current study evaluated the psychometric properties of the APQ-P using a community sample of 499 Portuguese mothers of children and adolescents aged 10 to 17 years. Confirmatory factor analysis revealed adequate psychometric properties of a three-factor model (positive parenting, ineffective parenting, and poor monitoring) in a solution of 20-items. After comparing the three-factor model across children’s age groups (≤13 vs. ≥14), partial metric and partial scalar invariance were found. Items loadings were similar between groups for ineffective parenting and poor monitoring, and factor scores were similar between groups for positive parenting. The 20-item version can be an appropriate measure of parenting, relevant for research and intervention purposes. Future studies should validate the current findings in independent samples, and devote particular attention to different parenting practices across different children’s age groups.     

The Five Dimensions of Pay Satisfaction in a Maquiladora Plant in Mexico

We examined the dimensionality of pay satisfaction using a Spanish language questionnaire and a sample of 236 maquiladora workers in Mexico. A confirmatory factor analysis indicated that a five-factor solution has the best fit compared to alternative models. Thus, blue-collar Mexican workers were able to distinguish five distinct facets of pay satisfaction: pay level, pay raises, benefits, pay structure/administration, and bonuses. This study replicates the five-factor structure of pay satisfaction in a Spanish-speaking sample of production workers in a maquiladora plant in Mexico.
Nous avons examiné la satisfaction relative au salaire en utilisant un questionnaire en langue espagnole sur un échantillon de 236 travailleurs d'une industrie maquiladora au Mexique. Une analyse factorielle confirmatoire a indiqué qu'une solution à cinq facteurs semble être le meilleur ajustement comparé aux alternatives possibles. Ainsi, les cols bleus mexicains sont capables de distinguer cing facettes de satisfaction relative au salaire: le niveau de salaire, son augmentation, sa gestion/son administration et les primes. Cette étude reproduit la structure en cinq facteurs de la satisfaction relative au salaire sur un échantillon hispanophone de travailleurs à la production d'une usine maquiladora au Mexique.     

Is Segmental Trunk Control Related to Gross Motor Performance in Healthy Preterm and Full-Term Infants?

Abstract

The authors’ aim was to verify the correlation between segmental trunk control and gross motor performance in healthy preterm (PT) and full-term (FT) infants aged 6 and 7?months and to verify if there are differences between groups. All infants were assessed at 6 and 7?months by means of Segmental Assessment of Trunk Control (SATCo) to identify the exact level of segmental trunk control and Alberta Infant Motor Scale (AIMS) to measure gross motor performance. A significant correlation between segmental trunk control and gross motor performance was found in healthy PT infants at 7?months and FT infants at 6?months. PT infants showed a delay on segmental trunk control at 6 and 7?months and in supported standing posture at 6?months compared with FT infants. Segmental trunk control and gross motor performance showed an important relationship in healthy PT and FT infants, mainly in sitting posture.     

Disfluencies, language comprehension, and Tree Adjoining Grammars

Disfluencies include editing terms such as uh and um as well as repeats and revisions. Little is known about how disfluencies are processed, and there has been next to no research focused on the way that disfluencies affect structure-building operations during comprehension. We review major findings from both computational linguistics and psycholinguistics, and then we summarize the results of our own work which centers on how the parser behaves when it encounters a disfluency. We describe some new research showing that information associated with misarticulated verbs lingers, and which adds to the large body of data on the critical influence of verb argument structures on sentence comprehension. The paper also presents a model of disfluency processing. The parser uses a Tree Adjoining Grammar to build phrase structure. In this approach, filled and unfilled pauses affect the timing of Substitution operations. Repairs and corrections are handled by a mechanism we term “Overlay,” which allows the parser to overwrite an undesired tree with the appropriate, correct tree. This model of disfluency processing highlights the need for the parser to sometimes coordinate the mechanisms that perform garden-path reanalysis with those that do disfluency repair. The research program as a whole demonstrates that it is possible to study disfluencies systematically and to learn how the parser handles filler material and mistakes. It also showcases the power of Tree Adjoining Grammars, a formalism developed by Aravind Joshi which has yielded results in many different areas of linguistics and cognitive science.
