Managing contested spaces: Public managers, obscured mechanisms and the legacy of the past in Northern Ireland

Societies emerging from ethno-political and inter-communal conflict face a range of complex problems that stem directly from the recent lived experience of bloodshed and injury, militarisation, securitisation and segregation. As institutional agents in such an environment, public managers perform the dual role of both interpreting public policy and implementing it within a politically contested space and place. In this article we address how managers cope with the outworking of ethno-nationalist conflict and peace building within government processes and policy implementation and contend this is a subject of emerging concern within the wider public administration, urban studies and conflict literature. Using data from a witness seminar initiative on the Northern Ireland conflict transformation experience, we explain how public sector managers make sense of their role in post-agreement public management and highlight the importance of three identified mechanisms; ‘bricolage’, ‘diffusion’ and ‘translation’ in the management of public sector organisations and urban spaces in a context of entrenched conflict and an uncertain path to peace

Medicare Expenditures and Healthcare Utilization in a Multi-ethnic Community-based Population with Dementia from Incidence to Death

Introduction: While individuals live with dementia for many years, utilization and expenditures from disease onset through the end-of-life period have not been examined in ethnically diverse samples. Methods: We used a multiethnic, population-based, prospective study of cognitive aging (Washington Heights-Inwood Columbia Aging Project) linked to Medicare claims to examine total Medicare expenditures and health care utilization among individuals with clinically diagnosed incident dementia from disease onset to death. Results: High-intensity treatment (hospitalizations, life-sustaining procedures) was common and mean Medicare expenditures per year after diagnosis was $69,000. Non-Hispanic blacks exhibited higher spending relative to Hispanics and non-Hispanic whites 1 year after diagnosis. Non-Hispanic blacks had higher total (mean=$205,000) Medicare expenditures from diagnosis to death compared with non-Hispanic whites (mean=$118,000). Hispanics’ total expenditures and utilization after diagnosis was similar to non-Hispanic whites despite living longer with dementia. Discussion: Health care spending for patients with dementia after diagnosis through the end-of-life is high and varies by ethnicity

Beyond incommensurability: Jerusalem and Stockholm from an ordinary cities perspective

This paper’s core argument is that we should start creating theories that encompass different cities and include them in a more flexible and relational comparative framework. This must include a new urban terminology which does not continue the all-too-fashionable labelling of cities on a continuum between first world and third world, global North-West and South-East or as I emphasize below, including what have been labelled extremely contested cities in a more flexible and relational ordinary cities framework. To introduce such a comparative approach, I will examine Jerusalem and Stockholm via three contrastive and relational patterns: institutional segregation; urban violence; and non-governmental organization involvement in planning. In so doing, I point towards the necessity to open up research on extreme urban conflicts, suggesting that when assessing specific contextual patterns, those labelled as extremely contested cities (such as Jerusalem) share more similarities with other more ordinary cities (represented by Stockholm) than was previously perceived, often stemming from ethnic, racial and class conflicts revolving around issues of politics, culture and identity, among others

Effect of sampling effort and sampling frequency on the composition of the planktonic crustacean assemblage: a case study of the river Danube

Although numerous studies have focused on the seasonal dynamics of riverine zooplankton, little is known about its short-term variation. In order to examine the effects of sampling frequency and sampling effort, microcrustacean samples were collected at daily intervals between 13 June and 21 July of 2007 in a parapotamal side arm of the river Danube, Hungary. Samples were also taken at biweekly intervals from November 2006 to May 2008. After presenting the community dynamics, the effect of sampling effort was evaluated with two different methods; the minimal sample size was also estimated. We introduced a single index (potential dynamic information loss; to determine the potential loss of information when sampling frequency is reduced. The formula was calculated for the total abundance, densities of the dominant taxa, adult/larva ratios of copepods and for two different diversity measures. Results suggest that abundances may experience notable fluctuations even within 1 week, as do diversities and adult/larva ratios

Large scale patterns in vertical distribution and behavior of mesopelagic scattering layers

Recent studies suggest that previous estimates of mesopelagic biomasses are severely biased, with the new, higher estimates underlining the need to unveil behaviourally mediated coupling between shallow and deep ocean habitats. We analysed vertical distribution and diel vertical migration (DVM) of mesopelagic acoustic scattering layers (SLs) recorded at 38 kHz across oceanographic regimes encountered during the circumglobal Malaspina expedition. Mesopelagic SLs were observed in all areas covered, but vertical distributions and DVM patterns varied markedly. The distribution of mesopelagic backscatter was deepest in the southern Indian Ocean (weighted mean daytime depth: WMD 590 m) and shallowest at the oxygen minimum zone in the eastern Pacific (WMD 350 m). DVM was evident in all areas covered, on average ~50% of mesopelagic backscatter made daily excursions from mesopelagic depths to shallow waters. There were marked differences in migrating proportions between the regions, ranging from ~20% in the Indian Ocean to ~90% in the Eastern Pacific. Overall the data suggest strong spatial gradients in mesopelagic DVM patterns, with implied ecological and biogeochemical consequences. Our results suggest that parts of this spatial variability can be explained by horizontal patterns in physical-chemical properties of water masses, such as oxygen, temperature and turbidity.En prensa2,927

Fractal analyses reveal independent complexity and predictability of gait

Locomotion is a natural task that has been assessed for decades and used as a proxy to highlight impairments of various origins. So far, most studies adopted classical linear analyses of spatio-temporal gait parameters. Here, we use more advanced, yet not less practical, non-linear techniques to analyse gait time series of healthy subjects. We aimed at finding more sensitive indexes related to spatio-temporal gait parameters than those previously used, with the hope to better identify abnormal locomotion. We analysed large-scale stride interval time series and mean step width in 34 participants while altering walking direction (forward vs. backward walking) and with or without galvanic vestibular stimulation. The Hurst exponent α and the Minkowski fractal dimension D were computed and interpreted as indexes expressing predictability and complexity of stride interval time series, respectively. These holistic indexes can easily be interpreted in the framework of optimal movement complexity. We show that α and D accurately capture stride interval changes in function of the experimental condition. Walking forward exhibited maximal complexity (D) and hence, adaptability. In contrast, walking backward and/or stimulation of the vestibular system decreased D. Furthermore, walking backward increased predictability (α) through a more stereotyped pattern of the stride interval and galvanic vestibular stimulation reduced predictability. The present study demonstrates the complementary power of the Hurst exponent and the fractal dimension to improve walking classification. Our developments may have immediate applications in rehabilitation, diagnosis, and classification procedures

Catalonia rescaling Spain : is it feasible to accommodate its "stateless citizenship"?

The Spanish nation-state is gradually being rescaled by Catalonia's “secession crisis.” Recently and dramatically, in the aftermath of the “illegal” and “constitutive referendum” that took place on 1 October 2017, 2,286,217 Catalan citizens attempted to exercise the “right to decide” to ultimately become “stateless citizens.” This paper examines this rescaling process that has been forming in Barcelona since 10 July 2010 when 1 million Catalan citizens marched to claim their “right to decide” on secession. This paper concludes that, at present, it is not feasible for the Spanish nation-state to accommodate Catalonia's “stateless citizenship.”
