Much of the current planning discourse has come to reject master planned ‘new cities’ as both unrealistic and undesirable. However, with growing urbanisation challenges in the Global South, master planned cities, suburbs and communities have come back on the agenda driven by both public and private interests. This paper explores the WesCape Development (WD), a proposed satellite suburb to be located north-west of Cape Town, South Africa. Situating the WD in a longer lineage of utopian and new city planning approaches, I argue that the proposal is deeply flawed. Rather than being the solution to the urban ills facing Cape Town, it is an ‘anti-urban’ strategy which supports suburbanisation and assumes a particular and problematic urban growth scenario. It relies on ‘environmentally deterministic’ assumptions and depoliticised and deinstitutionalised designs. Ultimately, it tries to escape, rather than confront, the operational, political and social challenges of the city leading to the devaluation of planning instruments and citizenship engagement. The WD highlights the importance and power of radical and utopian thinking as well as the necessity of grounding and situating these impulses in the specificities and complexities of the city.  相似文献

This study examined the impact of childhood sexual abuse history (CSA), gender, and theoretical orientation on treatment issues related to childhood sexual abuse. A survey of 501 clinicians found that 32% reported CSA histories. Sexually abused therapists were more likely to report some countertransference issues, especially boundary issues, than nonabused therapists, but gender differences were more important in determining differences in clinical practice. Female clinicians reported that CSA was more difficult to treat, that they screened more regularly for CSA, and that they utilized more coping strategies than male clinicians. Dissimilarities were also found between self-identified feminist therapists and psychoanalysts in their clinical practices, including the use of personality disorder diagnoses, reported countertransference issues, and coping strategies. Greater recognition of these issues in training programs is recommended. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Different causative therapeutics for CF patients have been developed. There are still no mutation-specific therapeutics for some patients, especially those with rare CFTR mutations. For this purpose, high-throughput screens have been performed which result in various candidate compounds, with mostly unclear modes of action. In order to elucidate the mechanism of action for promising candidate substances and to be able to predict possible synergistic effects of substance combinations, we used a systems biology approach to create a model of the CFTR maturation pathway in cells in a standardized, human- and machine-readable format. It is composed of a core map, manually curated from small-scale experiments in human cells, and a coarse map including interactors identified in large-scale efforts. The manually curated core map includes 170 different molecular entities and 156 reactions from 221 publications. The coarse map encompasses 1384 unique proteins from four publications. The overlap between the two data sources amounts to 46 proteins. The CFTR Lifecycle Map can be used to support the identification of potential targets inside the cell and elucidate the mode of action for candidate substances. It thereby provides a backbone to structure available data as well as a tool to develop hypotheses regarding novel therapeutics.  相似文献

If gender differences in recovery from childhood sexual abuse (CSA) go unrecognized, treatment may be unsuccessful. Gender differences in abuse characteristics, outcomes, and recovery are described for 131 therapists with CSA histories. Female clinicians reported more problems with self-esteem relationships, trust, sex, and work than males. Female clinicians identified several recovery experiences as more important: relinquishing guilt, talking about the abuse, renegotiating family-of-origin relationships, personal therapy, reading or writing about their CSA, hospitalization, and CSA workshops. Therapists working with male victims need to be aware of possible gender differences in symptom report and effects of healing strategies.

Today we live in a culture of institutionalised public realm – it is not the grass-roots activity of the 1970s. However, Liza Fior, Katherine Clarke and Sophie Handler of muf architecture explain how the collaborative nature of the practice, both internally and in its approach to any project brief, defines how, today, a community is as strong as the questions it is prepared to ask of itself.

The aim of this study was to determine if cortical motor representation and generators change after partial or complete paralysis after spinal cord injury (SCI). Previously reported evidence for a change in cortical motor function after SCI was derived from transcranial magnetic stimulation. These studies inferred a reorganization of the cortical motor system. We applied the new technique of high-resolution EEG to measure changes in cortical motor representation directly. We recorded and mapped the motor potential (MP) of the movement-related cortical potentials in 12 SCI patients and 11 control subjects. Results were analyzed using a distance metric to compare MP locations between patients and control subjects. EEG was coregistered with subject-specific MR images and a boundary element model created for dipole source analysis (DSA). When compared with normal control subjects, seven quadriparetics had posteriorly located MPs with finger movements. One paraparetic had a posterior MP with toe movements, but three who could not move the toes had normally located MPs on attempts to move. DSA confirmed the electrical field map distributions of the MPs. We are reporting a reorganization of cortical motor activity to a posterior location after SCI. These results suggest an important role of the somatosensory cortex (S1) in the recovery process after SCI.  相似文献

Electrospinning is a versatile method of producing continuous nanofibers through the application of an electric field. The simplest and earliest form of electrospinning involves the use of a single-needle spinneret to draw the solution out and form fibers. The process, however, is very time consuming, limiting the potential wide-scale application of electrospun nanofibers. Many multiple-jet electrospinning methods have been proposed to overcome the problem of low productivity, but the generation of multiple jets brought about other problems such as jet repulsion, lower process controllability, and deterioration of fiber quality. Thus, continuous development is necessary for the optimization of the process. The aim of this review is to provide an overview of the recent electrospinning technologies reported in the literature, particularly on various multiple-jet electrospinning methods from both nozzles and free surfaces. The general principle underlying the electrospinning process, as well as important parameters involved are also presented in this paper.  相似文献

Soiling of solar energy systems, or the accumulation of particulate matter on their surface, can cause significant losses in energy conversion efficiency. However, predicting these losses is still not done, as no methods exist. Field measurements of mass accumulation and airborne PM10 were conducted for more than one year at two sites in the Front Range of Colorado with the objective of developing soiling prediction models. For this study, only dry deposition was examined. The two sites, despite having different PM10 concentrations, have indistinguishable average effective deposition velocities of 2 cm/s, although a large spread in the data was noted. These results are similar to results found in other deposition studies. The observed effective deposition velocities indicate that coarse particles are a dominant player in mass accumulation, and sampled airborne size distributions support this hypothesis. Using a model to calculate dry deposition yielded better agreement with deposition than a simple average deposition velocity data fit. This model combined with other research and models can be used for estimating average soiling rates and is most useful over long time scales especially months to years or longer.

Background  

Rye products have previously been shown to induce comparatively low post-prandial insulin responses; irrespectively of their glycaemic indices (GI). However, the mechanism behind this lowered insulin demand remains unknown. An improved insulin economy might contribute to the benefits seen in epidemiological studies with whole grain diets on metabolic risk factors and weight regulation. The objective of this study was to explore the mechanism for a reduced post-prandial insulin demand with rye products.  相似文献
