Enhancing the mental representations of space used by blind pedestrians, based on an image schemata model

The configuration of mental representation of space plays a major role in successful navigational activities. Therefore, navigational assistance for pedestrians who are blind should help them to better configure their mental representation of the environment. In this paper, we propose and exploit a computational model for the mental representation of urban areas as an aid to orientation and navigation for visually impaired pedestrians. Our model uses image schemata to capture the spatial semantics and configural elements of urban space necessary for this purpose. These image schemata are schematic structures that are continually requested by individuals in their perception, bodily movement and interaction with surrounding objects. Our proposed model also incorporates a hierarchical structure to provide different levels of detail tied to appropriate spatial perspectives at each scale. We presume that such computational model will help us to develop an appropriate structure of spatial data used to assist the target population. At the end of the paper, we illustrate the utility of our configural model by developing a typical scenario for the navigation of a blind pedestrian in an urban area.     

Simple and integrated detours: field tests with Columbian ground squirrels

An internal representation of space offers flexibility to animals during orientation and allows execution of short cuts and detours. We tested the ability of 19 free-ranging Columbian ground squirrels (Spermophilus columbianus) to perform integrated detours that required travelling under- and aboveground. Squirrels were individually tested on their territories (2 tests) and in an arena (7 tests). During tests, animals could reach food by running aboveground and then through tunnels. For the territory tests, natural tunnels were available. For the arena tests, animals used artificial tunnels within a fenced-in part of the meadow. For the last arena test, tubes were placed aboveground replicating the underground structure. In this test animals were asked to make a simple detour, when the full path to the goal was visible. On their territories, 41% of squirrels performed detours. All animals reached the food in the arena. When choosing an arena detour, squirrels based their decision on the proximity of the burrow as well as on whether it led to food. On the last arena test, more squirrels performed correct detours on the first attempt compared to other tests. The results suggest that ground squirrels can perform simple and integrated detours, but animals perform better if the full path is visible.     

Adverse Life Events, Coping and Internalizing and Externalizing Behaviors in Urban African American Youth

African American youth residing in low income urban neighborhoods are at increased risk of experiencing negative life events in multiple domains, increasing their risk for internalizing and externalizing behaviors. However, little is known about youth’s differential responses to life event stress, or protective processes and coping strategies for urban African American youth exposed to adverse life events. Thus, the present study examined whether variability in predominantly low income, urban African American youth’s responses to life event stress are accounted for by the type of life event experienced or the type of coping strategies used. Participants were a community sample of 353 urban African American youth (52.8 % girls; age range 8–12 years) who participated in the Multiple Opportunities to Reach Excellence (MORE) Project. Youth reported about their experiences with adverse life events, coping strategies, and internalizing and externalizing symptoms. Results indicated that violent life events were uniquely associated with externalizing behavior, while discrimination and economic stress were uniquely associated with internalizing behavior. The utility of coping strategies varied by gender, such that avoiding problems was protective for girls who experienced violent life events, but not for boys. For boys, exposure to violence was significantly positively associated with externalizing symptoms regardless of the amount of avoiding problems coping used. Findings suggest that interventions to develop coping strategies may need to be gender-specific as well as tailored for the types of stressors common for low income urban youth.     

Experiencing,caring, coping: Vested interest mediates the effect of past experience on coping behaviors in environmental risk contexts

Social psychology provides a treasure-trove of insights into adaptations that may limit the devastating effects of climate change. Vested Interest Theory may contribute to this knowledge base, suggesting that one's vested interest may significantly influence appropriate coping behaviors, as it is has been shown to enhance the relation between attitudes and self-relevant behaviors. The theory's utility is investigated in an environmental risk context. Here, we replicate previous research findings showing that citizens in high-risk areas perceived higher risk and stronger intentions to cope with it when vested interest perceptions were salient. Furthermore, the current studies investigate the behavioral effect of vested interest on coping with an environmental risk (flooding): results showed that vested interest significantly mediated the past experience–coping behaviors relationship. In Study 1’s mediation analysis (Rome and Vibo Valentia, Italy, N = 466), past experience of flood risk enhanced vested interest in flood risk, which in turn increased volunteering for flood prevention activities, thereby mitigating risk. In Study 2 (N = 391), the same mediation effect was replicated in the Timis region, a high flood risk area in western Romania. These results shed light on literature inconsistencies on this topic, providing insights for the theoretical understanding of the relationship between past experience of a given risk and related coping behaviors, possibly shedding light to the risk perception paradox. These insights may drive effective intervention strategies to enhance people's behavioral coping with environmental risks.     

A methodology to assess the utility of future space systems

The Air Force SPACECAST 2020 study identified and prioritized some future space systems and technologies required in the next century. This paper presents the results of research on the SPACECAST 2020 value model. The model determines and prioritizes future space systems’ utility towards controlling and exploiting space. This research identifies the assumptions and simplifications in the additive utility function and assesses modifications. The research shows that mutual utility independence of the mission areas is a reasonable assumption. Mutual utility independence allows the use of the multiplicative and multilinear utility functions. Also, the SPACECAST 2020 scoring functions used the same scoring scale and only measured the utility of future capabilities. This study makes modifications to the SPACECAST 2020 measure-of-merit scoring functions. It replaces most of these functions with either a concave, convex, linear or ‘S’ scoring function, which have expanded capability ranges to include both current and future capabilities. The modified scoring functions and alternative utility functions do not alter the SPACECAST 2020 results but do improve the credibility and future usefulness of the model. This study shows that the initial assumption of using an additive utility function is also valid. © 1997 John Wiley & Sons, Ltd.     

Initial Validation of a Knowledge-Based Measure of Social Information Processing and Anger Management

Over the past fifteen years many schools have utilized aggression prevention programs. Despite these apparent advances, many programs are not examined systematically to determine the areas in which they are most effective. One reason for this is that many programs, especially those in urban under-resourced areas, do not utilize outcome measures that are sensitive to the needs of ethnic minority students. The current study illustrates how a new knowledge-based measure of social information processing and anger management techniques was designed through a partnership-based process to ensure that it would be sensitive to the needs of urban, predominately African American youngsters, while also having broad potential applicability for use as an outcome assessment tool for aggression prevention programs focusing upon social information processing. The new measure was found to have strong psychometric properties within a sample of urban predominately African American youth, as item analyses suggested that almost all items discriminate well between more and less knowledgeable individuals, that the test-retest reliability of the measure is strong, and that the measure appears to be sensitive to treatment changes over time. In addition, the overall score of this new measure is moderately associated with attributions of hostility on two measures (negative correlations) and demonstrates a low to moderate negative association with peer and teacher report measures of overt and relational aggression. More research is needed to determine the measure’s utility outside of the urban school context.     

Fairness,Self‐Interest,and Cooperation in a Real‐Life Conflict1

Effects of procedural fairness and self‐interest on cooperation vs. hardness in an urban planning conflict were examined in a questionnaire study. The self‐interest perspective posits that people seek to maximize their outcomes and, therefore, cooperate only when they can gain advantages or avoid disadvantages by doing so, while fairness models of cooperation view cooperative actions as based mainly on justice motives. The data give strong support for the fairness hypothesis, showing that self‐interest accounts only for hard strategies, whereas justice motives explain a considerable part of cooperation. The impact of the results on further research on social conflicts and their settlement, as well as the elaboration of models of fairness in the social psychology of conflicts are discussed.     

Miseries Suffered,Unvoiced, Unknown? Communication of Suicidal Intent by Men in “Rural” Queensland,Australia

It has long been argued that suicide prevention efforts in rural locations face not only structural barriers, such as a lack of accessible health care and specialized mental health services, but also a range of cultural barriers. A commonly discussed cultural factor that may contribute to higher rural suicide rates is low levels of help‐seeking behavior, which in turn act as a barrier to accessing and receiving care. However, the assumption that suicide by rural men is more likely to be accompanied by low help‐seeking behavior, relative to urban men, has not been well tested. Using data from the Queensland Suicide Register, this study evaluates one form of help‐seeking behavior—communication of suicidal intent—among men who died by suicide. Contrary to the expectation that suicide in rural areas would be associated with lower levels of help‐seeking behavior than suicide in urban areas, it was found that communication of suicidal intent was broadly comparable across rural and urban settings. The implications for suicide prevention policies and service delivery strategies are discussed.     

An Overview of Directions in Psychotherapy Integration Research

In general, empirical research in psychotherapy integration has lagged behind the growing theoretical and clinical interest in the field. Even though many of the theoretically integrative treatment models currently available are based on empirical findings and clinical observations, the models themselves remain, for the most part, untested. Rigorous examination of integrative psychological theories and therapeutic programs is a necessary and useful way to increase our understanding of the process of psychotherapy and establish the efficacy and effectiveness of integrative therapies. The present article explores five different research areas in the field of psychotherapy integration, discussing several published studies in each area. The utility of this research for practicing clinicians is also discussed. Additional investigations in these areas and others are encouraged, with the goals of greater understanding of psychotherapy, as well as the further development and acceptance of integrative approaches.     

Environmental influences on psychological restoration

Research on psychological restoration and restorative environments is a needed complement to work on stress and environmental stressors. Two laboratory experiments tested the utility of two restorative environments theories, one concerned with directed attention capacity renewal and the other with stress reduction and associated changes in emotion. Various strategies were employed to distinguish restorative effects from other effects, to limit the role of arousal reduction in attentional restoration, and to begin mapping the time course for the emergence of outcomes. Both experiments tested for differential emotional and performance effects as a function of photographic environmental simulation (natural or urban environment). Across the experiments the natural environment simulation engendered generally more positive emotional self-reports. That consistent performance effects were not found in either study suggests that attentional restoration as reflected in performance is a more time-intensive process.     

Exploring the links between gender,dwelling, and career orientations of African emerging adults

The study explored the socio-ecological (i.e. gender and geographical location) influences on the career orientations of emerging adults. The participants comprised a convenience sample of 159 black African South African university students (57% rural, 43% urban; 63% females, 37% males; mean age = 19.0, SD = 2.24). The emerging adults completed a career orientations inventory and also self-reported their demographics. We applied hierarchical regression analysis to predict the emerging adults’ career orientations from their gender and place of dwelling (geographical location) controlling for age. Results indicate that gender predicts interest in entrepreneurial creativity orientations for males rather than for females, and interest in service-oriented occupations for females compared to males. Geographical location predicted interest in entrepreneurial, general management, and service type of occupations for those from the rural rather than urban areas. Urban location predicted interest in technical and functional careers anchors. Career orientations among South African emerging adults appeared to be gendered and tied to place of geographical origin, suggesting social context socialisation influences.     

Attitudes Toward the Protection and Restoration of Natural Areas Across Three Geographic Levels: An Examination of Interattitude Consistency1

In addition to large, rural, pristine natural areas, urban open space is increasingly viewed as harboring small pockets of indigenous flora and fauna that need to be protected. We examined the consistency of attitudes toward protecting the natural environment among tropical rainforests, regional natural areas of the midwestern United States, and local open space within the Chicago metropolitan region. We also examined the moderating effects of issue importance, environmental ideology, and objective knowledge on attitude consistency. When environmental protection was rated as important, attitudes toward protecting tropical rainforests, regional forests, and local open space were more consistent with each other than when the issue was unimportant. Persons with distinct environmental ideologies differed in the extent to which their attitudes toward environmental protection at the three geographic levels were consistent.     

Acceptability of urban transport pricing strategies

Several research projects all over the world have considered transport pricing measures and policies as promising attempts to solve urgent traffic problems in urban areas. One important precondition for the successful implementation of pricing strategies is public acceptability. However, empirical findings have shown that the acceptability of such strategies is low. Until now economists have been looking for reasons for this refusal by analysing first of all socio-economic characteristics of the drivers concerned. But it is doubtful whether these alone have high explanatory value. Based on a heuristic acceptability model [IATSS Research 21 (1997) 134] different determinants of the acceptability of road pricing strategies are identified and analysed in more detail. A public acceptability survey was carried out in four European cities (N=952 motorists) to investigate two main questions. Firstly, how high is the current acceptability level of different urban transport pricing strategies? Secondly, do the factors as outlined in the acceptability model explain the level of acceptability? As expected, motorists’ stated acceptability of the investigated pricing strategies is rather low. Concerning the factors influencing the degree of acceptability the analyses showed that in particular the variables ‘social norm’, ‘personal outcome expectations’ and the ‘perceived effectiveness’ are positively related with the acceptability of pricing strategies. These variables account for nearly 40% of the criterion variance and thus can explain acceptability of such measures much better than the socio-economic variables included.     

Above and below the streets: A musical geography of anti-nuclear protest in Tokyo

Affects such as anger, fear and love have compelled Tokyoites to take to the streets in protest in the wake of the Fukushima nuclear disaster of March 2011. One of the characteristic forms these protests have taken has been the anti-nuclear “sound demonstrations” in which bands, DJs and rappers perform from the backs of trucks that lead demonstrators through the streets. Projecting their emotive music through urban space with the aid of powerful sound systems, these demonstrations disrupt the everyday noises of the neoliberal city and create a public space for the vocalisation of dissent. After the demonstrations, these same artists and demonstrators move to the underground live houses and social centres that constitute a subterranean backbone to the visible demonstrations in the street. Expressing emotions through musical protest is a powerful motor for what Stevphen Shukatitis has called affective composition, the process via which collective political subjectivities are formed through the expression of shared emotions. This paper outlines the emotional geography of anti-nuclear music in post-Fukushima Tokyo. It examines the dynamic interplay between aboveground political protest and the city's subterranean network of musical performance spaces.     

Parenting Styles and Adolescents' Learning Strategies in the Urban Community

The purpose of this study is to examine the relationship between perceived parenting styles and urban adolescents' learning and studying strategies. The results revealed that those adolescents who perceived their parents as being authoritative tended to engage in more effective learning and study strategies. Implications are discussed for counselors and teachers using this information as a fostering tool in their work with urban adolescents.     

Intra-Disciplinary Research as Progress in Philosophy: Lessons from Philosophy of the City

Philosophy of the city has recently emerged as a new subfield, garnering global interest. While most inquiries in this area have ‘the city’ or an urban issue as common ground, particular approaches engage in a kind of study identified as ‘intra-disciplinary research.’ An intra-disciplinary approach draws from different areas of philosophy to address problems that extend beyond the limits of individual subfields. A close examination reveals that this practice challenges assumptions holding that definitively answering philosophical questions is the only path to progress. Engaging in this kind of research adds to philosophy’s set of methods, and shows promise for philosophers wrestling with complex issues.     

The role of utility value in achievement behavior: the importance of culture

Two studies tested how participants' responses to utility value interventions and subsequent interest in a math technique vary by culture (Westerners vs. East Asians) and levels of initial math interest. Participants in Study 1 were provided with information about the utility value of the technique or not. The manipulation was particularly effective for East Asian learners with initially lower math interest, who showed more interest in the technique relative to low-interest Westerners. Study 2 compared the effects of two types of utility value (proximal or distal) and examined the effects on interest, effort, performance, and process variables. Whereas East Asian participants reaped the most motivational benefits from a distal value manipulation, Westerners benefited the most from a proximal value manipulation. These findings have implications for how to promote motivation for learners with different cultural backgrounds and interests.     

The impact of a rural or urban context in eating awareness and self‐regulation strategies in children and adolescents from eight European countries

Complex relationships exist between eating behaviour and personal and environmental factors. Rural and urban geographic contexts seem to play a role in eating behaviour, and therefore deserve a deeper study. A healthy eating behaviour and the conditions that promote it are a major issue in the promotion of adolescent health. The study aims to investigate the associations between the area of residence (urban vs. rural), self‐regulation strategies (TESQ‐E) and eating behaviours among children and adolescents. A total of 11,820 adolescents (50.6% girls) participated in the study, with a mean age of 13.30 years (SD= 2.13). Nine countries (The Netherlands, United Kingdom, Poland, Portugal, Denmark, Romania, Germany, Finland and Belgium) completed a questionnaire in the school context, asking about the use of self‐regulation strategies, eating behaviour awareness/care and sociodemographic questions such as age, gender and residential area. Both areas of residence (urban vs. rural) are associated with eating awareness/care in Romania and Portugal, controlling for age, gender and self‐regulation strategies. In some European countries at least, and most probably around the world, health promotion should focus on an ecological approach that includes the understanding of the effect of both environmental factors and personal skills on eating behaviour/awareness.
