Where would you turn for help?:Older adults' awareness of community support services

Previous findings on older adults' awareness of community support services (CSSs) have been inconsistent and marred by acquiescence or over-claiming bias. To address this issue, this study used a series of 12 vignettes to describe common situations faced by older adults for which CSSs might be appropriate. In telephone interviews, 1,152 adults aged 50 years and over were read a series of vignettes and asked if they were able to identify a community organization or agency that they may turn to in that situation. They were also asked about their most important sources of information about CSSs. The findings show that, using a vignette methodology, awareness of CSSs is much lower than previously thought. The most important sources of information about CSSs included information and referral sources, the telephone book, doctors' offices, and word of mouth.

Would older adults turn to community support services for help to maintain their independence?

The purpose of this article is to determine whether middle-aged and older adults would identify community support services (CSSs) as a source of assistance for difficulties with the instrumental activities of daily living (IADLs). Furthermore, we determine factors related to the identification of home health and CSSs. Telephone interviews were conducted with 768 adults aged 50 and older. Respondents were presented with a vignette describing a situation where loss of independence is threatened. They were asked what they would do in that situation. Although less than 20% mentioned CSSs, nearly 50% mentioned either a home health or CSS. Findings suggest those less likely to mention a home health or CSS include men, older adults, and the foreign born. In addition, those with less education, functional health limitations, no social support, and a lack of knowledge of where to find information about CSSs mentioned home health or CSSs less often. © The Author(s) 2010.

Cheetahs, Acinonyx jubatus, balance turn capacity with pace when chasing prey

Predator–prey interactions are fundamental in the evolution and structure of ecological communities. Our understanding, however, of the strategies used in pursuit and evasion remains limited. Here, we report on the hunting dynamics of the world's fastest land animal, the cheetah, Acinonyx jubatus. Using miniaturized data loggers, we recorded fine-scale movement, speed and acceleration of free-ranging cheetahs to measure how hunting dynamics relate to chasing different sized prey. Cheetahs attained hunting speeds of up to 18.94 m s-1 and accelerated up to 7.5 m s-2 with greatest angular velocities achieved during the terminal phase of the hunt. The interplay between forward and lateral acceleration during chases showed that the total forces involved in speed changes and turning were approximately constant over time but varied with prey type. Thus, rather than a simple maximum speed chase, cheetahs first accelerate to decrease the distance to their prey, before reducing speed 5–8 s from the end of the hunt, so as to facilitate rapid turns to match prey escape tactics, varying the precise strategy according to prey species. Predator and prey thus pit a fine balance of speed against manoeuvring capability in a race for survival.

Masks as methodology and the phenomenological turn: issues of interpretation

The purposes of this chapter are to argue for (i) the heuristic value of the concept of mask and masking in research which has its basis in psychodynamic theory but relating it to socio-cultural theory as means to understanding self-experience (ii) the value of creating and performing masks as one valuable methodological ‘embodied’ form in social and educational research that represent individuals’ richly textured self-other constructions and allow for the interrogation of any simplistic dichotomies associated with notions of ‘inside’ ‘outside’ categories (iii) exploring possibilities and dilemmas of interpretation within this frame

City visioning and the turn to community:The case of Derry/Londonderry

In the 1980s, urban re-imaging and place marketing were vital elements in the strategies of post-industrial cities aiming to redefine their role, make themselves more competitive and attract global investment and tourists. By the early 1990s, the questionable effects of trickle-down economics on deprived housing estates and the rediscovery of the 'community' as a social partner shifted both the substance and process of vision exercises. This paper examines the experience of building an input into a city vision that aimed to address social and ethno-religious segregation in Derry/Londonderry. Designing a consensus statement for a city that cannot agree its name, was wrecked by bloody violence and has its hinterland fractured by a contested international border, is a difficult and delicate process. The city had a population of 105 800 people in 1998, but is divided by the river Foyle between the mainly Catholic Cityside (to the north and west) and the mainly Protestant Waterside (to the south and east). The analysis connects with the literature on urban policy that emphasises the importance of argumentation and democratic debate in strategic planning and local regeneration (Forester, 1989; Healey, 1996). The paper concludes by arguing that strategies for 'listening' would help to shape a vision that could mobilise community interests around some common urban regional issues and help to promote social and ethno-religious polarisation as mainstream policy concerns.

The Modern Ordinary: Changing culture of living in Egypt’s traditional quarters at the turn of the twentieth Century

Having experienced social and political structures of the 19th century Europe, Western- educated Egyptian elite used public institutions to force legislative structures and procedures that ruled out traditional housing forms and spatial systems. This essay detects direct and indirect impact of these changes that informed the spatial change of modern living in Egypt in the first quarter of the twentieth century. It offers analysis of socio-spatial practices and change in ordinary Cairenes’ modes of everyday living, using social routine and interaction to explain spatial systems and changing house forms during the first quarter of the 20th century. In doing so, the essay utilized archival documents, accounts, formal decrees, and novels of the time as well as conducting survey of house forms and spatial organizations in Old Cairo.

Late Holocene sea-level fall and turn-off of reef flat carbonate production: Rethinking bucket fill and coral reef growth models

Relative sea-level rise has been a major factor driving the evolution of reef systems during the Holocene. Most models of reef evolution suggest that reefs preferentially grow vertically during rising sea level then laterally from windward to leeward, once the reef flat reaches sea level. Continuous lagoonal sedimentation ("bucket fill") and sand apron progradation eventually lead to reef systems with totally filled lagoons. Lagoonal infilling of One Tree Reef (southern Great Barrier Reef) through sand apron accretion was examined in the context of late Holocene relative sea-level change. This analysis was conducted using sedimentological and digital terrain data supported by 50 radiocarbon ages from fossil microatolls, buried patch reefs, foraminifera and shells in sediment cores, and recalibrated previously published radiocarbon ages. This data set challenges the conceptual model of geologically continuous sediment infill during the Holocene through sand apron accretion. Rapid sand apron accretion occurred between 6000 and 3000 calibrated yr before present B.P. (cal. yr B.P.); followed by only small amounts of sedimentation between 3000 cal. yr B.P. and present, with no significant sand apron accretion in the past 2 k.y. This hiatus in sediment infill coincides with a sea-level fall of similar to 1-1.3 m during the late Holocene (ca. 2000 cal. yr B.P.), which would have caused the turn-off of highly productive live coral growth on the reef flats currently dominated by less productive rubble and algal flats, resulting in a reduced sediment input to back-reef environments and the cessation in sand apron accretion. Given that relative sea-level variations of similar to 1 m were common throughout the Holocene, we suggest that this mode of sand apron development and carbonate production is applicable to most reef systems.

Holocene “turn-on” and evolution of the Southern Great Barrier Reef: Revisiting reef cores from the Capricorn Bunker Group

Extensive drilling of the Great Barrier Reef (GBR) in the 70s and 80s illuminated the main factors controlling reef growth during the Holocene. However, questions remain about: (1) the precise nature and timing of reef "turnon" or initiation, (2) whether consistent spatio-temporal patterns occur in the bio-sedimentologic response of the reef to Holocene sea-level rise then stability, and (3) how these factors are expressed in the context of the different evolutionary states (juvenile-mature-senile reefs). Combining 21 new C14-AMS and 146 existing recalibrated radiocarbon and U/Th ages, we investigated the detailed spatial and temporal variations in sedimentary facies and coralgal assemblages in fifteen cores across four reefs (Wreck, Fairfax, One Tree and Fitzroy) from the Southern GBR. Our newly defined facies and assemblages record distinct chronostratigraphic patterns in the cores, displaying both lateral zonation across the different reefs and shallowing upwards sequences, characterised by a transition from deep (Porites/faviids) to shallow (Acropora/Isopora) coral types. The revised reef accretion curves show a significant lag period, ranging from 0.7-2 ka, between flooding of the antecedent Pleistocene substrate and Holocene reef turn-on. This lag period and dominance of more environmentally tolerant early colonizers (e.g., domal Porites and faviids), suggests initial conditions that were unfavourable for coral growth. We contend that higher input of fine siliciclastic material from regional terrigenous sources, exposure to hydrodynamic forces and colonisation in deeper waters are the main factors influencing initially reduced growth and development. All four reefs record a time lag and we argue that the size and shape of the antecedent platform is most important in determining the duration between flooding and recolonisation of the Holocene reef. Finally, our study of Capricorn Bunker Group Holocene reefs suggests that the size and shape of the antecedent substrate has a greater impact on reef evolution and final evolutionary state (mature vs. senile), than substrate depth alone.
