Peak residential electricity demand and social practices: Deriving flexibility and greenhouse gas intensities from time use and locational data

Peak residential electricity demand takes place when people conduct simultaneous activities at specific times of the day. Social practices generate patterns of demand and can help understand why, where, with whom and when energy services are used at peak time. The aim of this work is to make use of recent UK time use and locational data to better understand: (i) how a set of component indices on synchronisation, variation, sharing and mobility indicate flexibility to shift demand; and (ii) the links between people’s activities and peaks in greenhouse gases’ intensities. The analysis is based on a recent UK time use dataset, providing 1 minute interval data from GPS devices and 10 minute data from diaries and questionnaires for 175 data days comprising 153 respondents. Findings show how greenhouse gases’ intensities and flexibility to shift activities vary throughout the day. Morning peaks are characterised by high levels of synchronisation, shared activities and occupancy, with low variation of activities. Evening peaks feature low synchronisation, and high spatial mobility variation of activities. From a network operator perspective, the results indicate that periods with lower flexibility may be prone to more significant local network loads due to the synchronization of electricity-demanding activities.

Locational and Temporal Risk Associated With Campus Sexual Assault

The present study investigates the rates of victimization of sexual assault reported by undergraduates at Bucknell University. Specifically, the study aimed to determine where and when sexual assault took place, in order to pinpoint both temporal risks and locational risks associated with certain events on campus. Results of the survey were analyzed for victimization rates across class year, time of year, where victimization took place, as well as where victims and perpetrators met. Data for the study was gathered by means of anonymous survey, sent out to 1752 randomly selected undergraduates via email. Participants filled out the survey which asked if they had ever been sexually assaulted or committed a sexual assault during their past year studying at Bucknell. The results of the survey indicated that dormitories, fraternity houses, and off-campus student houses displayed significantly higher rates of victimization than other locations. In addition, increased risk of unwanted sexual contact in the fall semester was shown to be statistically significant. Moreover, results of the current study support that parties were statistically significant locations for meeting perpetrators of sexual assault. The results suggest that it may be beneficial to direct special attention towards campus sexual assault, specifically to certain locations, times of the year, and campus activities.

Constellations of Disadvantage and Policy Dilemmas in Youth Transitions from School to Work in Bulgaria

In the past years there has been a growing concern in Europe with the drawbacks in youth transition from education to employment and social participation more generally (European Commission (EC) 2001

Neighborhood Disadvantage and Birth Weight: The Role of Perceived Danger and Substance Abuse

In this analysis we connect structural neighborhood conditions to birth outcomes through their intermediate effects on mothers’ perceptions of neighborhood danger and their tendency to abuse substances during pregnancy. We hypothesize that neighborhood poverty and racial/ethnic concentration combine to produce environments that mothers perceive as unsafe, thereby increasing the likelihood of negative coping behaviors (substance abuse). We expect these behaviors, in turn, to produce lower birth weights. Using data from the Fragile Families and Child Wellbeing Study, a survey of a cohort mothers and children born between 1998 and 2000 in large cities in the United States, we find little evidence to suggest that neighborhood circumstances have strong, direct effects on birth weight. Living in a neighborhood with more foreigners had a positive effect on birth weight. To the extent that neighborhood conditions influence birth weight, the effect mainly occurs through an association with perceived neighborhood danger and subsequent negative coping behaviors. Poverty and racial/ethnic concentration increase a mother’s sense that her neighborhood is unsafe. The perception of an unsafe neighborhood, in turn, associates with a greater likelihood of smoking cigarettes and using illegal drugs, and these behaviors have strong and significant effects in reducing birth weight. However, demographic characteristics, rather than perceived danger or substance abuse, mediate the influence of neighborhood characteristics on birth weight.

Locational policies in secondary capital cities: constructing a dynamic framework

Capital cities that are not the economic centers of their nations – so-called secondary capital cities (SSCs) – tend to be overlooked in the field of political science. Consequentially, there is a lack of research and resulting theory describing their local economy and their public policies. This paper analyzes how SCCs try to develop and position themselves through the formulation of locational policies. By linking three different theoretical strands – the Regional Innovation System (RIS) approach, the concept of locational policies, and the regime perspective – this paper aims for constructing a framework to study the economic and political dynamics in SCCs.

Innovation, Coordination, and Positioning: Locational Policies of Secondary Capital City Regions

Capital cities that are not the economic centers of their nations - so-called secondary capital cities - tend to be overlooked in the field of political science. Consequentially, there is a lack of research and resulting theory describing their political economy and their formulated policies. This paper analyzes how secondary capital cities try to develop and position themselves through the formulation of locational policies. By linking three different theoretical strands - the Regional Innovation System approach, the concept of locational policies, and the regime perspective - this paper proposes a framework to study the the economic and political dynamics in secondary capital cites.

Same same but different: Locational policies in small and medium-sized European cities

Globalized interurban competition is affecting cities of various sizes and locations. Small and medium-sized cities have to find ways to position themselves in global markets by formulating locational policies. This paper outlines an analytical framework of locational policies that cities adopt in order to increase their competitiveness. By comparing two European small and mediumsized cities (Lucerne and Ulm), we examine manifestations of locational policies and compare if these policies are being diverse or resemble each other. We found that strategies of both cities are sharing the intentions to be competitive, but their policy choices differ because the economic and political context is enabling or restricting certain kinds of locational policies. Furthermore, the findings point to the high explanatory power of municipal tax autonomy when studying locational policies.

An ecologic comparison study of the impact of economic disadvantage on Texas Assessment of Knowledge and Skills performance, graduation rates, and readiness for higher education for students attending public and charter schools in Texas from 2004 to 2006

Purpose. No Child Left Behind aimed to "improve the academic achievement of the disadvantaged." The primary research question considered how academic achievement of those from economic disadvantage compared to those not from disadvantage? ^ Economically disadvantaged students can potentially have added academic disadvantage. Research shows low academic achievement can potentially result in drug abuse, youth violence, and teen pregnancy. ^ Methods. To compare the student populations, measures included TAKS results and academic indicator data collected by the Texas Education Agency. ^ Results. T-test analyses showed a significant difference between the economically and non-economically disadvantaged student populations in meeting the TAKS passing standard, graduation, and preparation for higher education.^ Conclusions. The achievement gap between students remained as indicated by the Texas testing program. More research and time are needed to observe if the desired impact on those from economic disadvantage will be reflected by academic achievement data.^
