During employment of icons in order to represent system functions, specific user requirements from elderly people have not been scientifically gathered and thus will merely be considered during the process of system design. The survey, with explicit consideration of technology acceptance and experience of 120 elderly probands, looked into the comprehension of four different classes of non-animated graphical representations. It was shown that among elderly, the use of photos compared to pictograms or clip art leads to a significantly higher recognition rate. The mapping of actions rather than objects leads to a further reduction of the error probability and is thus, especially in the context of telemedicine, preferable for the target group. 相似文献

Augmented Reality focuses on the enrichment of the user's natural field of view by consistent integration of text, symbols and interactive three-dimensional objects in real time. Placing virtual objects directly into the user's view in a natural context empowers highly dynamic applications. On the other hand, this necessitates deliberate choice of information design and density, in particular for deployment in hazardous environments like military combat scenarios. As the amount of information needed is not foreseeable and strongly depends on the individual mission, an appropriate system must offer adequate adaptation capabilities. The paper presents a prototypical, vehicle-mountable Augmented Reality vision system, designed for enhancing situation awareness in stressful urban warfare scenarios. Tracking, as one of the most crucial challenges for outdoor Augmented Reality, is accomplished by means of a Differential-GPS approach while the type of display to attach can be modified, ranging from ocular displays to standard LCD mini-screens. The overall concept also includes envisioning of own troops (blue forces), for which a multi-sensor tracking approach has been chosen. As a main feature, the system allows switching between different information categories, focusing on friendly, hostile, unidentified or neutral data. Results of an empirical study on the superiority of an in-view navigation cue approach conclude the paper. 相似文献

Gerontolinguistic obtains a growing importance with the increase of elderly users due to Demographic Change. Since acceptance and ease of use of supportive systems for elderly, such as "E-Nursing-Assistants", are highly dependent on the age suitable design of readable instructions, an age-appropriate linguistic concept is of high value for usability. There has been only little research on the relevance of foreign words, signal words, textual arrangement, optical accentuation of key terms and temporal iconicity concerning older users. Thus, an efficient design of age suitable manual instructions within a medical context still remains to be done. The objective of this research was to evaluate the relevance of the previously mentioned factors in the context of written instructions. For this, an empirical survey was designed which was given to 45 study participants. The subjects of the experiment were given 4x3 instructions after a pretest questionnaire. The aim was to execute these instructions as correctly and quickly as possible. Furthermore the instructions were rated regarding comprehensibility with a retrospective questionnaire. 相似文献

While a growing literature demonstrates the impact of socio-political factors on citizens’ quality of life, scholars have
paid comparatively little attention to the role political organizations such as labor unions play in this regard. We examine
labor organization as a determinant of cross-national variation in life satisfaction across a sample of advanced industrial
polities. Our findings strongly suggest that unions increase the life satisfaction of citizens, and that that this effect
holds for non-union members as well. Moreover, we also find that labor organization has the strongest impact on the subjective
well-being of citizens with lower incomes. We confirm these hypotheses using both individual and aggregate-level data from
fourteen nations. We show these relationships to have an independent and separable impact from other economic, political,
and cultural determinants. The implications for the study of life satisfaction and of labor unions as political actors in
general are discussed. 相似文献

The paper explores diglossic relations between Central Thai and phasa isan, a variety officially known as a dialect of Thai, but linguistically close to Lao. Phasa isan is spoken by almost one‐third of Thailand's population but its speakers in the Northeast are often stigmatized as uneducated and backward. We conducted field research mainly among university students in Ubon Ratchathani, a northeastern border province, by drawing upon data from survey questionnaires, reflective essays, interviews, and field observations. The findings suggest a transitional diglossic relationship in which Central Thai is the High and phasa isan the Low variety. These relationships are discussed in terms of nationalism, social hierarchy, and language maintenance and shift. 相似文献

Germany is currently experiencing a huge inflow of migrants. In this vignette study, we analyze how much different kinds of migrants are accepted in Germany. We investigate three different rights for migrants: the right to stay in Germany, the right to work in Germany and the right to receive social benefits. Our results show that people who flee from political persecution are much more accepted compared to migrants who come because of economic reasons. This is particularly true for the right to receive social benefits. On the other hand, our results suggest that there is a strong preference for high-skilled and culturally non-distant migrants. Concerns regarding individual competition on the job market seem to play only a minor role. 相似文献

Although appearance-based cues can help to diagnose physical illness, visual manifestations of mental disorder may be more elusive. Here, we investigated whether individuals could distinguish women with a serious mental disorder (borderline personality disorder) from demographically- and IQ-matched non-psychiatric controls. Participants rated mentally ill targets as more likely to have a mental disorder from photos more accurately than chance, despite not believing that such judgments were possible. The configuration of facial cues played an important role in these judgments, as interfering with the spatial relationships between facial features reduced participants’ accuracy to chance guessing. Further investigation showed similar results when participants rated the targets for specific mental disorders (borderline personality disorder, major depressive disorder) and rated the mentally ill targets as more depressed, angry, anxious, disgusted, emotionally unstable, distressed, and less happy. Moreover, the depression ratings significantly correlated with the targets’ actual depressive symptoms. Thus, individuals may be able to infer aspects of mental disorder from minimal facial cues. 相似文献

This study estimates the relationship between combat exposure and several risky health behaviors: cigarette consumption, binge drinking, and drug use. We find that the U.S. active duty military personnel deployed to combat zones with enemy firefight are more likely to subsequently smoke cigarettes, consume alcohol, and use illicit drugs than their counterparts deployed to noncombat operations. Our results suggest that the mental health effects of combat can explain up to two‐thirds of the estimated association between combat exposure and risky health behaviors. (JEL H56, I12) 相似文献

Since its introduction, Prahalad and Bettis's concept of dominant logic has informed a variety of scholarly conversations in management and strategy research. However, scholars have interpreted dominant logic in different ways, emphasizing different aspects, such as managerial mindsets, administrative tools and management functions, as defining elements. Similarly, empirical studies have captured various aspects, such as meanings of entrepreneurs, observable strategic decisions and business model similarity, as indicators of dominant logic. Consequently, the concept lacks analytical clarity, and it is difficult to compare or generalize findings from this diverse set of studies. The aim of this review is to improve conceptual clarity by analysing, comparing and evaluating the existing interpretations and assessments of dominant logic in 94 studies. In the first part of the review, by disentangling the interpretations of the concept, we show that dominant logic consists of four defining dimensions: (i) shared mental models; (ii) values and premises; (iii) organizational practices; and (iv) organizing structures. In the second part, we reassemble dominant logic into an integrative model and theorize about how these dimensions operate in concert to produce a firm's dominant logic. Thus, our main contribution is a clarification and synthesis of the literature, which comes with implications on how future research can conceptualize and operationalize dominant logic more consistently. 相似文献
