Critical success factors in urban brownfield regeneration: an analysis of ‘hardcore’ sites in Manchester and Osaka during the economic recession (2009–10)

Hardcore, or long-term derelict and vacant brownfield sites which are often contaminated, form a significant proportion of brownfield land in many cities, not only in the UK but also in other countries. The recent economic recession has placed the economic viability of such sites in jeopardy. This paper compares the approaches for bringing back hardcore brownfield sites into use in England and Japan by focusing on ten case studies in Manchester and Osaka, using an `agency'-based frame- work. The findings are set in the context of (i) national brownfield and related policy agendas; (ii) recent trends in land and property markets in both England and Japan; and (iii) city-level comparisons of brownfields in Manchester and Osaka. The research, which was conducted during 2009 ^ 10, suggests that hardcore brownfield sites have been badly affected by the recent recession in both Manchester and Osaka. Despite this, not only is there evidence that hardcore sites have been successfully regenerated in both cities, but also that the critical success factors (CSFs) operating in bringing sites back into use share a large degree of commonality. These CSFs include the presence of strong potential markets, seeing the recession as an opportunity, long-term vision, strong branding, strong partnerships, integrated development, and getting infrastructure into place. Finally, the paper outlines the policy implications of the research.

Ketamine, propofol, and the EEG: A neural field analysis of HCN1-mediated interactions

Ketamine and propofol are two well-known, powerful anesthetic agents, yet at first sight this appears to be their only commonality. Ketamine is a dissociative anesthetic agent, whose main mechanism of action is considered to be N-methyl-D-aspartate (NMDA) antagonism; whereas propofol is a general anesthetic agent, which is assumed to primarily potentiate currents gated by γ-aminobutyric acid type A (GABAA) receptors. However, several experimental observations suggest a closer relationship. First, the effect of ketamine on the electroencephalogram (EEG) is markedly changed in the presence of propofol: on its own ketamine increases θ (4–8 Hz) and decreases α (8–13 Hz) oscillations, whereas ketamine induces a significant shift to beta band frequencies (13–30 Hz) in the presence of propofol. Second, both ketamine and propofol cause inhibition of the inward pacemaker current Ih, by binding to the corresponding hyperpolarization-activated cyclic nucleotide-gated potassium channel 1 (HCN1) subunit. The resulting effect is a hyperpolarization of the neuron’s resting membrane potential. Third, the ability of both ketamine and propofol to induce hypnosis is reduced in HCN1-knockout mice. Here we show that one can theoretically understand the observed spectral changes of the EEG based on HCN1-mediated hyperpolarizations alone, without involving the supposed main mechanisms of action of these drugs through NMDA and GABAA, respectively. On the basis of our successful EEG model we conclude that ketamine and propofol should be antagonistic to each other in their interaction at HCN1 subunits. Such a prediction is in accord with the results of clinical experiment in which it is found that ketamine and propofol interact in an infra-additive manner with respect to the endpoints of hypnosis and immobility.

The place of diversity within history and the challenge of policy and curriculum

This article is a position paper which examines the political and public discourse around the areas of diversity and social cohesion, and history teaching. It examines the nature of these discourses and shows how they are in tension. Although discourse around diversity often has a focus on mutual understanding and finding areas of commonality, the discourse around history often focuses on the need to provide a sense of identity through a national story. By focusing on a discussion about the purposes of history, rather than merely on debates about content, it is suggested that these discourses can be brought more closely into line and produce a more productive line of policy debate.

Neuroanatomy of individual differences in language in adult males with autism

One potential source of heterogeneity within autism spectrum conditions (ASC) is language development and ability. In 80 high-functioning male adults with ASC, we tested if variations in developmental and current structural language are associated with current neuroanatomy. Groups with and without language delay differed behaviorally in early social reciprocity, current language, but not current autistic features. Language delay was associated with larger total gray matter (GM) volume, smaller relative volume at bilateral insula, ventral basal ganglia, and right superior, middle, and polar temporal structures, and larger relative volume at pons and medulla oblongata in adulthood. Despite this heterogeneity, those with and without language delay showed significant commonality in morphometric features when contrasted with matched neurotypical individuals (n = 57). In ASC, better current language was associated with increased GM volume in bilateral temporal pole, superior temporal regions, dorsolateral fronto-parietal and cerebellar structures, and increased white matter volume in distributed frontal and insular regions. Furthermore, current language–neuroanatomy correlation patterns were similar across subgroups with or without language delay. High-functioning adult males with ASC show neuroanatomical variations associated with both developmental and current language characteristics. This underscores the importance of including both developmental and current language as specifiers for ASC, to help clarify heterogeneity.

Software reuse: The Brazilian industry scenario

This paper aims at identifying some of the key factors in adopting an organization-wide software reuse program. The factors are derived from practical experience reported by industry professionals, through a survey involving 57 Brazilian small, medium and large software organizations. Some of them produce software with commonality between applications, and have mature processes, while others successfully achieved reuse through isolated, ad hoe efforts. The paper compiles the answers from the survey participants, showing which factors were more associated with reuse success. Based on this relationship, a guide is presented, pointing out which factors should be more strongly considered by small, medium and large organizations attempting to establish a reuse program.

Se inicia oração com pronome clítico? Atitudes linguísticas, na escola, em relação aos padrões brasileiros de colocação pronominal

Focusing on the empirical assessment issue, proposed by Language change theory (cf. cf. WEINREICH; LABOV; HERZOG, 2006; LABOV, [1972] 2008), this research assists to clarifying Portuguese teacher s attitudes in Natal- RN, regarding (a) to proclisis in three specific contexts: in the beginning of a simple/compound sentence (V1), after the subjects (SV), and proclisis after the secondary verb in complex verbal structures (V1V2); (b) to students who use such patterns in usage. Specific contexts were gathered thanks to their representing of the standard variety, as many studies have proven (Martins, 2012; Schei, 2003; Biazzoli, 2010, 2012). The research aims at: (i) verifying by means of a classroom assessment test, whether Portuguese teachers correct proclisis on referred contexts; (ii) identifying, via attitudinal tests what actions teachers take regarding to the usage of standards above mentioned, as well as students as users of those. Twenty Portuguese teachers, picked at random out of different of public schools in Natal-RN, responded to a classroom assessment test in addition to other two attitudinal ones. Results achieved point to a recurring high proclisis correction index of 50% in simple/compound sentences, even though such variety has been implemented to pronominal usage standards in Brazilian Portuguese. This setting of usage was generally assessed negatively, having no commonality between this assessment and the neutral one used by students. Unlike previous setting, the proclisis after subject did not receive any correction of the twenty teachers, what proves coherence with the positive evaluation both the varieties and the students attained. As for the second verb of complex verbal structures, proclisis correction went negative on presenting single results, despite their proximity, with correction indexes of 20% (infinite structures), 10% (present progressive structures) and 25% (participle structures). The assessment on these contexts of proclisis ranged between positive and neutral, also valid for the one students utilized. It means that proclisis in the beginning of simple/compound sentences are yet seemingly spotted in writing school scenario, much likely due to the negative evaluation, opposite to students . Later to subjects and earlier to secondary verbs in structures, proclisis appears to be acknowledged in writing school scenarios, which reflects on teachers assessment as compared to students who use proclisis in these contexts; being in general either positive or neutral

From archives to archival science Elements for a discursive construction

This work tries to outline the theoretical background established by archival science manuals, based mainly on discourse analysis as a key discipline to understand which the differences are and points of conceptual commonality in archival science traditions studied that to some extent, are additional. As archival science is a product of historically constructed knowledge, the context of conceptual production ultimately reflects in the different schools of thought and in the methodological approach. The manuals discussed here were selected by their canon and their wide dissemination in the archival science field, and are: the Manual for the arrangement and description of archives of the Association of Dutch Archivists (1898), and Jenkinson's A manual of archive administration including the problems of war archives and archive making. We considered how in these manuals two key concepts are discussed as for organization methodology in archival science: description and classification, establishing, from these concepts, which are the intertwined discourses in these texts and relating them to their historical aspects.

Ghana@50 – celebrating the nation: an eyewitness account from Accra /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 83

This article offers an account of the 50th Ghanaian independence-day celebrations during March 2007. The multi-perspective approach examines how celebrations were experienced in the Ghanaian capital Accra by the political elite and the grass roots at a variety of official and unofficial events that took place on 5 and 6 March 2007. During the festivities the authors accompanied Ghanaian friends from different political factions and thus provide close-hand accounts of political controversies over issues regarding how the nation ought to organise and celebrate its Independence Day, controversies which provide important insights into Ghanaian political culture. From this it is clear that the celebrations not only serve as expressions of national pride but also moments of critical reflection on the nation, national values and socio-political unity. These reflections, manifest as disputes about national and ethnic symbols, centre on the conditions and limits of political, social, ethnic and regional inclusiveness. At the same time, underlying such disputes are commonalities resting not on substantive symbols, cultural traits or other objectifiable characteristics, but on a Ghanaian consensus to agree on the issues at stake and on the rules of debate. Controversy thus functions not to divide but rather to strengthen national consciousness and deepen a sense of commonality that Ghanaians generally express as their commitment to ‘unity in diversity’.

Core networks for visual-concrete and abstract thought content: a brain electric microstate analysis

Commonality of activation of spontaneously forming and stimulus-induced mental representations is an often made but rarely tested assumption in neuroscience. In a conjunction analysis of two earlier studies, brain electric activity during visual-concrete and abstract thoughts was studied. The conditions were: in study 1, spontaneous stimulus-independent thinking (post-hoc, visual imagery or abstract thought were identified); in study 2, reading of single nouns ranking high or low on a visual imagery scale. In both studies, subjects' tasks were similar: when prompted, they had to recall the last thought (study 1) or the last word (study 2). In both studies, subjects had no instruction to classify or to visually imagine their thoughts, and accordingly were not aware of the studies' aim. Brain electric data were analyzed into functional topographic brain images (using LORETA) of the last microstate before the prompt (study 1) and of the word-type discriminating event-related microstate after word onset (study 2). Conjunction analysis across the two studies yielded commonality of activation of core networks for abstract thought content in left anterior superior regions, and for visual-concrete thought content in right temporal-posterior inferior regions. The results suggest that two different core networks are automatedly activated when abstract or visual-concrete information, respectively, enters working memory, without a subject task or instruction about the two classes of information, and regardless of internal or external origin, and of input modality. These core machineries of working memory thus are invariant to source or modality of input when treating the two types of information.

America's Shifting Color Line? Reexamining Determinants of Latino Racial Self-Identification

Objectives. Latinos are the nation's largest minority group and will double in size by 2050. Their size coupled with the fact that Latinos do not constitute a separate race raises questions about Latinos' incorporation into the U. S. racial hierarchy. This article explores patterns of Latino racial identity formation, examining the determinants of racial identity. Methods. Using the 2006 Latino National Survey, I estimate multinomial logit and ordered probit models of identification choices. Results. Latino racial identity is strongly associated with several factors, including socioeconomic status, measures of perceived discrimination and commonality, and measures of acculturation/assimilation. Most Latinos have a broader, more complex understanding of race. Furthermore, some Latinos do believe that they occupy a unique position in the racial hierarchy. Conclusions. The results suggest that the color line W. E. DuBois argued has long divided our nation may eventually shift.

Properties of tooth enamel in great apes

A comparative study has been made of human and great ape molar tooth enamel. Nanoindentation techniques are used to map profiles of elastic modulus and hardness across sections from the enamel–dentin junction to the outer tooth surface. The measured data profiles overlap between species, suggesting a degree of commonality in material properties. Using established deformation and fracture relations, critical loads to produce function-threatening damage in the enamel of each species are calculated for characteristic tooth sizes and enamel thicknesses. The results suggest that differences in load-bearing capacity of molar teeth in primates are less a function of underlying material properties than of morphology.

Evaluation of the accuracy of multilevel analysis parameter estimates for intra-cluster correlation in correlated binary data

Many studies in biostatistics deal with binary data. Some of these studies involve correlated observations, which can complicate the analysis of the resulting data. Studies of this kind typically arise when a high degree of commonality exists between test subjects. If there exists a natural hierarchy in the data, multilevel analysis is an appropriate tool for the analysis. Two examples are the measurements on identical twins, or the study of symmetrical organs or appendages such as in the case of ophthalmic studies. Although this type of matching appears ideal for the purposes of comparison, analysis of the resulting data while ignoring the effect of intra-cluster correlation has been shown to produce biased results.^ This paper will explore the use of multilevel modeling of simulated binary data with predetermined levels of correlation. Data will be generated using the Beta-Binomial method with varying degrees of correlation between the lower level observations. The data will be analyzed using the multilevel software package MlwiN (Woodhouse, et al, 1995). Comparisons between the specified intra-cluster correlation of these data and the estimated correlations, using multilevel analysis, will be used to examine the accuracy of this technique in analyzing this type of data. ^
