This article explores the development of an aesthetics framework that aims to provide designers with parameters to understand emotion, taste, and aesthetic judgment under their own cultural influence. This framework will equip designers with tangible criteria for judging cultural influences that have an impact on industrial design while preventing designers from adopting subjective options or being "followers of the current trend." To address the complexity of the topic, a systemic approach is taken so as to be able to capture its several elements. Therefore, the aesthetics framework adopts a systemic approach, which enables its constituents to be compared and the interplay or "links" between these different elements to be identified.  相似文献

The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user's context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.  相似文献

Alterations made in the architectural design can be considered as a continuous process, from its conception to the moment a built environment is already in use. This article focuses on the "moving phase", which is the initial moment of the environment occupation and the start-up of services. It aims to show that the continuity of ergonomics interventions during the "moving phase" or start up may reveal the built environment inadequacies; clearly showing needs not met by the design and allowing making instant decisions to solve non-foreseen problems. The results have revealed some lessons experienced by users during a critical stage not usually included in the design process.  相似文献

Increased urbanization typically leads to an increase in abundance of a few species and a reduction in bird species richness. Understanding the structure of biotic communities in urban areas will allow us to propose management techniques and to decrease conflicts between wild species and human beings. The objective of this study was to describe the structure of the bird community in an urban ecosystem. The study was carried out in the city of Taubaté in southeastern Brazil. Point-counts were established in areas with different levels of tree density ranging from urban green spaces to predominantly built-up areas. We looked for a correlation between the richness/abundance of birds and the size of the area surveyed, the number of houses, the number of tree species and the number of individual trees. The results of multiple regression showed that bird richness had a direct relationship with vegetation complexity. The abundance and diversity of tree species were better predictors of bird species than the number of houses and size of the area surveyed. We discuss implications of this study for conservation and management of bird diversity in urban areas, such as the need to increase green areas containing a large diversity of native plant species.  相似文献

The purpose of this study was to compare the neuromuscular adaptations produced by strength-training (ST) and power-training (PT) regimens in older individuals. Participants were balanced by quadriceps cross-sectional area (CSA) and leg-press 1-repetition maximum and randomly assigned to an ST group (n = 14; 63.6 ± 4.0 yr, 79.7 ± 17.2 kg, and 163.9 ± 9.8 cm), a PT group (n = 16; 64.9 ± 3.9 yr, 63.9 ± 11.9 kg, and 157.4 ± 7.7 cm), or a control group (n = 13; 63.0 ± 4.0 yr, 67.2 ± 10.8 kg, and 159.8 ± 6.8 cm). ST and PT were equally effective in increasing (a) maximum dynamic and isometric strength (p < .05), (b) increasing quadriceps muscle CSA (p < .05), and (c) decreasing electrical mechanical delay of the vastus lateralis muscle (p < .05). There were no significant changes in neuromuscular activation after training. The novel finding of the current study is that PT seems to be an attractive alternative to regular ST to maintain and improve muscle mass.  相似文献

Objective: Since vitamin D is an important regulator of muscle function, the effect of vitamin D deficiency on frailty syndrome has been recently studied. This cross-sectional study aimed to determine the association between 25(OH)-vitamin D levels and frailty status in Mexican community-dwelling elderly.

Methods: Sample of 331 community-dwelling elderly aged 70 or older, a subset of those included in the “Coyoacán cohort” were included. 25(OH)-vitamin D assay and frailty status were measured.

Results: Mean age was 79.3 years and 54.1% were women. Those classified as frail were more likely to have lower Mini-Mental State Examination score (p?=?0.015), more disability for instrumental activities of daily living (p?p?p?Conclusion: These results suggest that older adults with low 25(OH)-vitamin D levels are associated with the probability to being frail compared with those with sufficient vitamin D levels.  相似文献

This study examined how acceptability of placebo gel with receptive anal intercourse (RAI) and likelihood of future rectal microbicide use varied across partner types. Because no rectal microbicide is available yet, use of placebo permitted the study of gel use behavior in real-life circumstances. A total of 87 men who have sex with men (MSM) aged 18 to 30 years inserted placebo gel rectally before RAI during 12 weeks. Using mixed-methods design, participants completed a behavioral questionnaire and in-depth interview. In all, 62 men (71.3%) reported gel use with a lover (i.e., spouse equivalent, boyfriend), 32 (36.8%) with a one-night stand (i.e., man with whom you had sex once), and 29 (33.3%) with an “other” male partner. While gel acceptability was high across partner types, use with lovers was facilitated by trust and familiarity; yet trust made participants believe protection was less necessary. Conversely, participants expressed high likelihood of using gel with one-night stands, whom they perceived as riskier; yet they felt less comfortable discussing gel with them, often resorting to covert use or forgoing gel. A successful microbicide will be positioned as a sexual pleasure enhancer so that men can present it to their lovers and other partners as a gel that improves sex and secondarily prevents human immunodeficiency virus (HIV).  相似文献

In this paper, an exploratory content analysis has been developed for a case study on the topic of immigration reported in the regional newspapers of the largest Spanish autonomous community, Castilla and Leon. This study based its research conceptualization on the framing theory in mass communication. In addition to usual issue frames and issue images, two framing devices were established for analytic variables ‐‐ the index of importance and the index of affective attribute. They formed a frame package capable of making latent frames evident by their linkage to manifest frames. Comparing to the general assumption of relevant‐bad‐news production, results obtained in this study proved that, on occasion, negative news stories could be reported as less relevant than the positive ones. The outcomes also show how concept mapping of frames was applicable to immigration issues and immigrants’ visual aspects of immigrant communities that were systematically articulated and disseminated by the press in this regional society of Spain.  相似文献

The age of a patient is a strong moderator of both the course and the evolution of disorders/diseases. However, the effects of current age in pathological gambling (PG) have rarely been examined. The aim of this study is to explore the moderating effects of the patients’ current age in relation to personality traits and clinical outcomes of PG. A total sample of 2,309 treatment-seeking patients for PG, diagnosed according to DSM-IV criteria, participated in this study and were assessed with the Diagnostic Questionnaire for Pathological Gambling according to DSM-IV criteria, the South Oaks Gambling Screen, the Symptom Checklist, the Temperament and Character Inventory-R, and other clinical and psychopathological measures. Orthogonal polynomial contrasts showed linear trends in the relationship between age and PG: the older the patient, the more comorbid health problems were visible. The presence of additional quadratic trends also suggests that age plays a significant role in moderating the possibility of existing PG problems and general psychopathology. No interaction term was found between age and sex, but it was present for age and some personality traits: self-transcendence and reward dependence (these two traits were only relevant to the level of impairment due to PG at specific ages). This study suggests that the patients’ age influences psychopathological and clinical aspects associated to PG. Intervention in the earliest manifestations of this complex problem is essential in order to better address the need of successful treatment planning.  相似文献
