Assessing Future Expectations and the Two-Dimensional Model of Affect in an Italian Population
2017
Future-directed thinking has been described as part of two underlying systems that integrate dimensions of affect, motivational systems, orientation to the future, and future expectations, which are initiated at the cognitive, affective, biological, behavioral, and motivational levels. The main aim of the present study is to test the two underlying frameworks model and explore future expectations in a general Italian-speaking population (N=345). Therefore, the second aim of the present paper is to confirm the factorial structure of the Subjective Probability Task (SPT; MacLeod et al., 1996), a questionnaire designed to assess specific positive and negative orientations towards the future. R…
Determinants of leisure-time physical activity and future intention to practice in Spanish college students
2009
Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and…
Microvascular Characteristics of the Human Interdental Papilla
2007
The aim of this study was to observe the microcirculation characteristics of the human interdental papilla in healthy patients in vivo. Twenty healthy patients were examined. Capillaroscopy was used to investigate the characteristics of microcirculation of the human periodontal mucosa. Visibility, course, tortuosity, as well as the average caliber of the capillary loops and the number of visible capillary loops per square millimeter were evaluated for each patient. The investigation of gingival mucosa revealed capillary loops with a course both parallel and perpendicular to the surface. Our study has pointed out that capillaroscopy is a reliable method to study periodontal microcirculation …
Microvascular characteristics of the human filiform papillae: a videocapillaroscopic study
2006
The aim of this study was to observe the microcirculation characteristics of the human filiform papillae in healthy patients in vivo. Twenty healthy patients were examined using lingual capillaroscopy to investigate the characteristics of microcirculation of the human filiform papillae. Visibility, course, tortuosity, as well as the possible presence of microhemorrhages, the average caliber of the capillary loops and the number of visible capillary loops per square millimeter were evaluated for each patient. The investigation was simple, non-invasive and repeatable for each patient. Microcirculation architecture was characterized by a network of capillaries in polygonal mesh with parallel o…
Are postural responses to backward and forward perturbations processed by different neural circuits?
2013
Item does not contain fulltext Startle pathways may contribute to rapid accomplishment of postural stability. Here we investigate the possible influence of a startling auditory stimulus (SAS) on postural responses. We formulated four specific questions: (1) can a concurrent SAS shorten the onset of automatic postural responses?; and if so (2) is this effect different for forward versus backward perturbations?; (3) does this effect depend on prior knowledge of the perturbation direction?; and (4) is this effect different for low- and high-magnitude perturbations? Balance was perturbed in 11 healthy participants by a movable platform that suddenly translated forward or backward. Each particip…
Mechanical step variability during treadmill running.
1995
The present study was designed to study intra-individual step variability measured both on vertical displacement of the body (delta Z) and on step time (delta t) parameters by means of a kinematic arm and during treadmill running. A group of 17 subjects ran successively at 60%, 80%, 100% and 140% of their maximal aerobic velocity (Vamax). The total number of steps analysed was 6116. The absolute delta Z step variability (sigma delta Z) ranged between 5 mm and 21 mm while the absolute delta t variability (sigma delta t) ranged between 6 ms and 40 ms. Step variabilities were due to step asymmetry (from 38.5% to 48.5% of the step variability) and to stride variability. For submaximal velocitie…
Region-dependent hamstrings activity in Nordic hamstring exercise and stiff-leg deadlift defined with high-density electromyography
2018
Recent studies suggest region-specific metabolic activity in hamstring muscles during injury prevention exercises, but the neural representation of this phenomenon is unknown. The aim of this study was to examine whether regional differences are evident in the activity of biceps femoris long head (BFlh) and semitendinosus (ST) muscles during two common injury prevention exercises. Twelve male participants without a history of hamstring injury performed the Nordic hamstring exercise (NHE) and stiff-leg deadlift (SDL) while BFlh and ST activities were recorded with high-density electromyography (HD-EMG). Normalized activity was calculated from the distal, middle, and proximal regions in the e…
Constant, cycling, hot and cold thermal environments: strong effects on mean viability but not on genetic estimates
2012
It has frequently been suggested that trait heritabilities are environmentally sensitive, and there are genetic trade-offs between tolerating different environments such as hot and cold or constant and fluctuating temperatures. Future climate predictions suggest an increase in both temperatures and their fluctuations. How species will respond to these changes is uncertain, particularly as there is a lack of studies which compare genetic performances in constant vs. fluctuating environments. In this study, we used a nested full-sib/half-sib breeding design to examine how the genetic variances and heritabilities of egg-to-adult viability differ at high and low temperatures with and without da…
Il clima dell’Antropocene: disamina realistica di alcune sfide di una nuova epoca
2021
The chapter systematizes and describes the ecological, conceptual, normative, and policy challenges of the Anthropocene, with a focus on the climatic transformations underway. Il looks at various scales of action and inaction, and suggests that ideal theorizing may be significantly out of step with some defining circumstances of the new epoch
A future of journalism beyond the objectivity-dialogue divide? : Hybridity in the news of entrepreneurial journalists
2019
As pioneers of new ideas and practices, many entrepreneurial journalists spearhead the change of journalism towards hybridity. By applying appraisal theory, this article examines a hybrid of objectivity and dialogue in daily news articles by five entrepreneurial journalism outlets – Axios, MustRead, National Observer, The Skimm and the Voice of San Diego. For comparative purposes, a dataset from three legacy media outlets was also analysed. The results show that the entrepreneurial journalism outlets employ journalistic dialogue in otherwise stylistically objective news texts notably more often than do legacy media outlets. Dialogic registers provide subtle, non-partisan assessments of eve…
