Abstract:

In recent years, bottom-up urban development has started growing as an alternative to conventional top-down planning. In large proportions, citizens and communities initiate small-scale interventions; suddenly seeming to form a trend. As a result, more and more cities are witnessing not only the growth of but also an interest in these initiatives, as they bear the potential to reshape urban spaces. Such alternative city-making efforts cause new dynamics in urban governance, with inevitable consequences for the controlled city planning and its administration. The emergence of enabling relationships between top-down and bottom-up actors signals an increasingly common urban practice. Various case studies show that an enabling relationship is possible, yet, how it can be optimally realized stays rather underexamined. Therefore, the seemingly growing worldwide phenomenon of ‘municipal bottom-up urban development’ necessitates an adequate governance structure. As such, the aim of this research is to contribute knowledge to how municipalities can enable citizen-led urban initiatives from a governance innovation perspective. Empirical case-study research in Stockholm and Istanbul, derived from interviews with founders of four citizen-led urban initiatives and one municipal representative in each city, provided valuable insights to possibilities and constraints for enabling practices. On the one hand, diverging outcomes emphasize the extreme oppositional features of both cases (Stockholm and Istanbul). Firstly, both cities’ characteristics are drastically different. Secondly, the ideologies and motifs for the initiatives to emerge vary widely. Thirdly, the major constraints for citizen-led urban initiatives to relate to the municipality are considerably different. Two types of municipality’s organizational structures produce different underlying mechanisms which demonstrate the constraints. The first municipal organizational structure is steered by bureaucracy (Stockholm). It produces an administrative division that brings up constraints such as the lack of responsibility, transparency and continuity by municipal representatives. The second structure is dominated by municipal politics and governmental hierarchy (Istanbul). It produces informality, lack of transparency and a fragmented civil society. In order to cope with the constraints produced by both types of organizational structures, the initiatives have adjusted their organization to the municipality’s underlying structures. On the other hand, this paper has in fact also come to a rather unifying conclusion. Interestingly, the suggested possibilities for an enabling relationship underline converging new urban governance arrangements. This could imply that for the two varying types of municipality’s organizational structures there is an accurate governance structure. Namely, the combination of a neighborhood council with a municipal guide, with allowance for the initiatives to adopt a politicizing attitude is found as coinciding. Especially its combination appears key to redeem varying constraints. A municipal guide steers the initiatives through bureaucratic struggles, is supported by coproduction methods, while it balances out municipal politics. Next, a neighborhood council, that is politically neutral and run by local citizens, can function as an umbrella for citizen-led urban initiatives. What is crucial is that it should cater for a more entangled relationship between municipalities and initiatives with enhanced involvement of the initiatives in decision-making processes and limited involvement of prevailing constraints pointed out in this research.

Abstract:

Background: The monitoring of the physiological activity related to mental workload (MW) on pilots will be useful to improve aviation safety by anticipating human performance degradation. The electrocardiogram (ECG) can reveal MW fluctuations due to either cognitive workload or/and emotional state since this measure exhibits autonomic nervous system modulations. Arguably, heart rate (HR) is one of its most intuitive and reliable parameters. It would be particularly interesting to analyze the interaction between cognitive requirements and emotion in ecologic sets such as a flight simulator. This study aims to explore by means of HR the relation between cognitive demands and emotional activation. Presumably, the effects of cognition and emotion overloads are not necessarily cumulative. Methodology: Eight healthy volunteers in possession of the Private Pilot License were recruited (male; 20.8±3.2 years). ECG signal was recorded along the whole experiment by placing two electrodes on the clavicle and left pectoral of the participants. The HR was computed within 4 minutes segments. NASA-TLX and Big Five inventories were used to assess subjective workload and to consider the influence of individual personality differences. The experiment consisted in completing two dual-tasks of approximately 30 minutes of duration into a flight simulator AL50. Each dual-task required the simultaneous accomplishment of both a pre-established flight plan and an additional task based on target stimulus discrimination inserted between Air Traffic Control instructions. This secondary task allowed us to vary the cognitive workload from low (LC) to high (HC) levels, by combining auditory and visual numerical stimuli to respond to meeting specific criteria. Regarding emotional condition, the two dual-tasks were designed to assure analogous difficulty in terms of solicited cognitive demands. The former was realized by the pilot alone, i.e. Low Arousal (LA) condition. In contrast, the latter generates a high arousal (HA), since the pilot was supervised by two evaluators, filmed and involved into a mock competition with the rest of the participants. Results: Performance for the secondary task showed significant faster reaction times (RT) for HA compared to LA condition (p=.003). Moreover, faster RT was found for LC compared to HC (p < .001) condition. No interaction was found. Concerning HR measure, despite the lack of main effects an interaction between emotion and cognition is evidenced (p=.028). Post hoc analysis showed smaller HR for HA compared to LA condition only for LC (p=.049). Conclusion. The control of an aircraft is a very complex task including strong cognitive demands and depends on the emotional state of pilots. According to the behavioral data, the experimental set has permitted to generate satisfactorily different emotional and cognitive levels. As suggested by the interaction found in HR measure, these two factors do not seem to have a cumulative impact on the sympathetic nervous system. Apparently, low cognitive workload makes pilots more sensitive to emotional variations. These results hint the independency between data processing and emotional regulation. Further physiological data are necessary to confirm and disentangle this relation. This procedure may be useful for monitoring objectively pilot’s mental workload.

Abstract:

Background: Dramatic physical development, socioemotional adjustment, and cognitive changes highlight adolescent development. Adolescent brains are susceptible to emotional reactivity, making them likely to engage in risk-taking and impulsive behaviors. The family is crucial in laying the foundations of good health. Aims: This study determined the degree of family cohesion, quality of father-child and mother-child relationships, and degree of academic pressure across cultures, age groups, and sexual orientations. Further, it sought the prevalence of adolescent health concerns, including suicide risks, risk-taking behaviors, social media engagement, and self-care deviations. Finally, the correlations between health risk behaviors and the elements of family dynamics were unraveled. Methods: The descriptive-correlational design served as the blueprint for this study. Data were collected from 1095 adolescents aged 12-21 in two high schools and two universities in Baguio City using self-report questionnaires. Data was analyzed using Microsoft Excel Toolpak and IBM SPSS Statistics to identify significant differences and relationships among variables through descriptive statistics (frequency, %, means and figures) and inferential statistics (ANOVA and logistic regression). Results and Discussion: Adolescents generally have strong family cohesion (FC), high-quality father-child relationships (F-CR), very high-quality mother-child relationships(M-CR), and experience high academic pressure (AP). Cultural affiliation does not influence the 4 elements of family dynamics; the higher the age, the stronger the family cohesion; males score significantly higher on family cohesion and mother-child relationship while significantly lower in perceived academic pressure compared to their female and LGBT counterparts. Suicide risk is prevalent among 29-63% of the population, safety issues have the lowest prevalence for having an abusive relationship (8.22%) and the highest for encountering major family changes (53.52%). Substance use was highest for vaping (22.74%), sexual engagement occurs in 14.61% of the population, while 63% are engaged in social media for >5 hours/day. The self-care deviation is highest for weight concerns (63.39%), lack of visits to health care professionals (64.65%) and lack of exercise (49.94%). All 4 elements of family dynamic (FC, F-CR, M-CR and AP) are significantly associated with safety concerns, suicide risks and social media engagement, while M-CR significantly influences cigarette smoking, alcohol drinking, rugby use and engagement in sex. Conclusion and Recommendations: Strong family cohesion and quality parent-child interactions improve emotional and behavioral outcomes. Sexual orientation has a significant impact on academic pressure and social media use, demanding targeted treatments. The link between family dynamics and health-risk behaviors emphasizes the importance of promoting positive family relationships and encouraging safer behaviors, which are critical for increasing adolescents' well-being.
