Financial ideas, political constraints : the IPE of sovereign wealth funds
Rather than ponder sovereign wealth funds' (SWFs ') significance for global capital markets, this thesis takes a step back and asks the following: why do SWFs exist in such numbers across the global political economy? The SWF literature, dominated by fmancial economists and neoliberal commentators, has yet to adequately address this puzzle. This is significant given the funds embed systematically significant amounts of national wealth throughout speculative capital markets, thereby increasing their state's vulnerability to recurrent asset bubbles and crises. The thesis consequently examines the interest-based politics behind SWFs' domestic origins. It begins its analysis with the argument that SWFs are first and foremost domestic strategies of governance created to achieve specific short and medium term goals of the administrative state. This is despite their international and long-term investment orientations. In short, the funds serve to immediately stabilize state actors' governance function by reconceptualising problems of uncertainty in the quantitative and manageable terms of fmancial risk. This account of SWFs' origins thus contests that currently dominating mainstream commentary, which portrays the funds as evolutionary features of modem fmance capitalism. The domestic political interests SWFs were initially created to serve consequently remain critically unexamined. Drawing from the constructivist institutionalism literature, the thesis also seeks to demonstrate that SWFs are the institutional embodiment of a specific array of prescriptive fmancial ideas. It will be shown this framework offmancial 'knowledge' problematically constrains political actors to defer their interests to the demands of the speculative fmancial realm. In the face of recurrent crises, such constraint highlights how SWFs' immediate impact on domestic socioeconomic spheres outweighs their imagined fmancial benefits. The funds' rapid expansion since 2000 therefore poses significant implications for the nature and exercise of sovereign authority in SWF-states. These theoretical arguments are developed in Part I of the thesis, and then tested against three case studies in Part II: Norway's Government Pension Fund-Global; Alberta's Heritage Savings Trust Fund; and Ireland's National Pension Reserve Fund.EThOS - Electronic Theses Online ServiceUniversity of WarwickGBUnited Kingdo
A Natural Resource-Systems approach: Targeting the Ecological Transition at the Regional Scale
Chapitre de l’ouvrage collectif Penser une démocratie alimentaire Volume II – Proposition Lascaux entre ressources naturelles et besoins fondamentaux, F. Collart Dutilleul et T. Bréger (dir), Inida, San José, 2014, pp. 143-167.International audienceHuman history can be mirrored in a geo-history of natural resources. Humans, by over-exploiting resources (“forcing”), have produced extensive land use changes and have altered complex food webs, ecosystems, and habitats with as a consequence systematic natural biocapacity erosion, biodiversity loss, energy crises, pollution, climate deregulation. In other terms, a global resources “rush” has led to chronic socio-ecosystemic deficits, thus creating the conditions for local and global state shifts within the biosphere and / or society.Therefore, research must serve to increase human understanding of those resources and how best to use them for the public good

Estimating spatial accessibility to facilities on the regional scale: an extended commuting-based interaction potential model
<p>Abstract</p> <p>Background</p> <p>There is growing interest in the study of the relationships between individual health-related behaviours (e.g. food intake and physical activity) and measurements of spatial accessibility to the associated facilities (e.g. food outlets and sport facilities). The aim of this study is to propose measurements of spatial accessibility to facilities on the regional scale, using aggregated data. We first used a potential accessibility model that partly makes it possible to overcome the limitations of the most frequently used indices such as the count of opportunities within a given neighbourhood. We then propose an extended model in order to take into account both home and work-based accessibility for a commuting population.</p> <p>Results</p> <p>Potential accessibility estimation provides a very different picture of the accessibility levels experienced by the population than the more classical "number of opportunities per census tract" index. The extended model for commuters increases the overall accessibility levels but this increase differs according to the urbanisation level. Strongest increases are observed in some rural municipalities with initial low accessibility levels. Distance to major urban poles seems to play an essential role.</p> <p>Conclusions</p> <p>Accessibility is a multi-dimensional concept that should integrate some aspects of travel behaviour. Our work supports the evidence that the choice of appropriate accessibility indices including both residential and non-residential environmental features is necessary. Such models have potential implications for providing relevant information to policy-makers in the field of public health.</p
Assessment of sedentary behaviors and transport-related activities by questionnaire: a validation study
ACTI-Cités consortiumInternational audienceBackground: Comprehensive assessment of sedentary behavior (SB) and physical activity (PA), including transport-related activities (TRA), is required to design innovative PA promotion strategies. There are few validated instruments that simultaneously assess the different components of human movement according to their context of practice (e.g. work, transport, leisure). We examined test-retest reliability and validity of the Sedentary, Transportation and Activity Questionnaire (STAQ), a newly developed questionnaire dedicated to assessing context-specific SB, TRA and PA. Methods: Ninety six subjects (51 women) kept a contextualized activity-logbook and wore a hip accelerometer (Actigraph GT3X + TM) for a 7-day or 14-day period, at the end of which they completed the STAQ. Activity-energy expenditure was measured in a subgroup of 45 subjects using the double labeled water (DLW) method. Test-retest reliability was assessed using intra-class-coefficients (ICC) in a subgroup of 32 subjects who filled the questionnaire twice one month apart. Accelerometry was annotated using the logbook to obtain total and context-specific objective estimates of SB. Spearman correlations, Bland-Altman plots and ICC were used to analyze validity with logbook, accelerometry and DLW data validity criteria. Results: Test-retest reliability was fair for total sitting time (ICC = 0.52), good to excellent for work sitting time (ICC = 0.71), transport-related walking (ICC = 0.61) and car use (ICC = 0.67), and leisure screen-related SB (ICC = 0.64-0.79), but poor for total sitting time during leisure and transport-related contexts. For validity, compared to accelerometry, significant correlations were found for STAQ estimates of total (r = 0.54) and context-specific sitting times with stronger correlations for work sitting time (r = 0.88), and screen times (TV/DVD viewing: r = 0.46; other screens: r = 0.42) than for transport (r = 0.35) or leisure-related sitting-times (r = 0.19). Compared to contextualized logbook, STAQ estimates of TRA was higher for car (r = 0.65) than for active transport (r = 0.41). The questionnaire generally overestimated work-and leisure-related SB and sitting times, while it underestimated total and transport-related sitting times.Conclusions : The STAQ showed acceptable reliability and a good ranking validity for assessment of context-specific SB and TRA. This instrument appears as a useful tool to study SB, TRA and PA in context in adults
Descriptive study of sedentary behaviours in 35,444 French working adults: cross-sectional findings from the ACTI-Cités study
International audienceBackground : Given the unfavourable health outcomes associated with sedentary behaviours, there is a need to better understand the context in which these behaviours take place to better address this public health concern. We explored self-reported sedentary behaviours by type of day (work/non-work), occupation, and perceptions towards physical activity, in a large sample of adults.Methods : We assessed sedentary behaviours cross-sectionally in 35,444 working adults (mean ± SD age: 44.5 ± 13.0 y) from the French NutriNet-Santé web-based cohort. Participants self-reported sedentary behaviours, assessed as domain-specific sitting time (work, transport, leisure) and time spent in sedentary entertainment (TV/DVD, computer and other screen-based activities, non-screen-based activities) on workdays and non-workdays, along with occupation type (ranging from mainly sitting to heavy manual work) and perceptions towards physical activity. Associations of each type of sedentary behaviour with occupation type and perceptions towards physical activity were analysed by day type in multiple linear regression analyses.Results : On workdays, adults spent a mean (SD) of 4.17 (3.07) h/day in work sitting, 1.10 (1.69) h/day in transport sitting, 2.19 (1.62) h/day in leisure-time sitting, 1.53 (1.24) h/day viewing TV/DVDs, 2.19 (2.62) h/day on other screen time, and 0.97 (1.49) on non-screen time. On non-workdays, this was 0.85 (1.53) h/day in transport sitting, 3.19 (2.05) h/day in leisure-time sitting, 2.24 (1.76) h/day viewing TV/DVDs, 1.85 (1.74) h/day on other screen time, and 1.30 (1.35) on non-screen time. Time spent in sedentary behaviours differed by occupation type, with more sedentary behaviour outside of work (both sitting and entertainment time), in those with sedentary occupations, especially on workdays. Negative perceptions towards physical activity were associated with more sedentary behaviour outside of work (both sitting and entertainment time), irrespective of day type.Conclusions : A substantial amount of waking hours was spent in different types of sedentary behaviours on workdays and non-workdays. Being sedentary at work was associated with more sedentary behaviour outside of work. Negative perceptions towards physical activity may influence the amount of time spent in sedentary behaviours. These data should help to better identify target groups in public health interventions to reduce sedentary behaviours in working adults
