Historicizing counterurbanization: in-migration and the reconstruction of rural space in Berkshire (UK), 1901-51

This article uses census data for Berkshire to argue that large-scale counterurbanization began much earlier than is generally recognized in some parts of southern England. This was not just movement down the urban hierarchy, which as Pooley and Turnbull have demonstrated was a long-term feature of England’s settlement system, but in some cases at least amenity-driven migration to rural areas of the kind increasingly recognized as a core component of recent counterurbanization. Despite a reduction of acreage Berkshire’s rural districts saw a 54% rise in population between 1901 and 1951. The sub-regional pattern of growth is assessed to gauge whether ‘clean break’ migration to the remote west of the county (which remained effectively out of commuting range from London throughout the period) was taking place, or whether counterurbanization was confined to the more accessible eastern districts. However, whilst population did increase in both west and east, it was in fact the central districts that grew most impressively. Three case study parishes are investigated in order to gauge the nature and consequences of counterurbanization at a local level. Professional and business migrants figure prominently, seeking to preserve and promote the rural attributes of their new communities, without however cutting their ties to urban centres. It is argued that migration to rural Berkshire in the first half of the twentieth century cannot adequately be described either as a form of extended suburbanization or an anti-metropolitan ‘clean break’. Rather, early counterurbanization marks the first stage on the long road to a post-productivist countryside, in which countryside becomes detached from agriculture, there is socio-economic convergence between town and country, and the ‘rural’ increasingly becomes defined by landscape and identity rather than economic function.

Measurements of stratospheric ozone at a mid-latitude observing station Valentia, Ireland (51.94° N, 10.25° W), using ground-based and ozonesonde observations from 1994 to 2009

Sixteen years (1994 – 2009) of ozone profiling by ozonesondes at Valentia Meteorological and Geophysical Observatory, Ireland (51.94° N, 10.23° W) along with a co-located MkIV Brewer spectrophotometer for the period 1993–2009 are analyzed. Simple and multiple linear regression methods are used to infer the recent trend, if any, in stratospheric column ozone over the station. The decadal trend from 1994 to 2010 is also calculated from the monthly mean data of Brewer and column ozone data derived from satellite observations. Both of these show a 1.5 % increase per decade during this period with an uncertainty of about ±0.25 %. Monthly mean data for March show a much stronger trend of ~ 4.8 % increase per decade for both ozonesonde and Brewer data. The ozone profile is divided between three vertical slots of 0–15 km, 15–26 km, and 26 km to the top of the atmosphere and a 11-year running average is calculated. Ozone values for the month of March only are observed to increase at each level with a maximum change of +9.2 ± 3.2 % per decade (between years 1994 and 2009) being observed in the vertical region from 15 to 26 km. In the tropospheric region from 0 to 15 km, the trend is positive but with a poor statistical significance. However, for the top level of above 26 km the trend is significantly positive at about 4 % per decade. The March integrated ozonesonde column ozone during this period is found to increase at a rate of ~6.6 % per decade compared with the Brewer and satellite positive trends of ~5 % per decade.

The Article 51 reporting requirement for self-defense actions

This article examines one legal criterion for the exercise of the right of self-defense that has been significantly overlooked by commentators: the so-called “reporting requirement.” Article 51 of the United Nations (UN) Charter provides, inter alia, that “[m]easures taken by members in the exercise of this right of self-defense shall be immediately reported to the Security Council.” Although the requirement to report all self-defense actions to the Council is clearly set out in Article 51, the Charter offers no further guidance with regard to this obligation. Reference to the practice of states since the UN’s inception in 1945 is therefore essential to understanding the scope and nature of the reporting requirement. As such, this article is underpinned by an extensive original dataset of reporting practice covering the period from January 1, 1998 to December 31, 2013. We know from Article 51 that states “shall” report, but do they, and—if so—in what manner? What are the various implications of reporting, of failing to report, and of the way in which states report? How are reports used, and by whom? Most importantly, this article questions the ultimate value of states reporting their self-defense actions to the Security Council in modern interstate relations.

Intragroup diffuse light in compact groups of galaxies - II. HCG 15, 35 and 51

This continuing study of intragroup light in compact groups of galaxies aims to establish new constraints to models of formation and evolution of galaxy groups, specially of compact groups, which are a key part in the evolution of larger structures, such as clusters. In this paper we present three additional groups (HCG 15, 35 and 51) using deep wide-field B- and R-band images observed with the LAICA camera at the 3.5-m telescope at the Calar Alto observatory (CAHA). This instrument provides us with very stable flat-fielding, a mandatory condition for reliably measuring intragroup diffuse light. The images were analysed with the OV_WAV package, a wavelet technique that allows us to uncover the intragroup component in an unprecedented way. We have detected that 19, 15 and 26 per cent of the total light of HCG 15, 35 and 51, respectively, are in the diffuse component, with colours that are compatible with old stellar populations and with mean surface brightness that can be its low as 28.4 B mag arcsec(-2). Dynamical masses, crossing times and mass-to-light ratios were recalculated using the new group parameters. Also tidal features were analysed using the wavelet technique.

Devaluation of a constitutional guarantee : the history of section 51(xxiiiA) of the Commonwealth Constitution

This article describes constitutional and socio-historical background to the referendum that led to the inserrion of s 51(xxiijA) into the Commonwealth Constitution. It traces judicial interpretations of the clause 'but not so as to authorise any fonn of civil conscription' through the major cases, including British Medical Association v Commonwealth, General Practitioners Society v Commonwealth, and Alexandra Private Geriatric Hospital Pty Ud v Commonwealth. The issue of the powers of the Commonwealth to regulate private medical practice without infringing the constitutional guarantee against civil conscription is analysed in the context of the development of National Health Care Schemes for financing medical benefits (Health Insurance Commission v Peverill). Constitutional aspects of the 1995 legislation enabling the introduction into Australia of purchaser-provider agreements ('managed care ') are also examined. Finally, the article questions the constitutionality of the Australian Competition and Consumer Commission s powers to regulate the essential elements of the patient-doctor relationship.

When is property inherently defeasible for the purposes of s 51(xxxi)?

This article traces the development of the jurisprudence surrounding compulsory acquisition of property with a particular focus on the application of s 51(xxxi) of the Australian Constitution to statutory property. The examination reveals a clearly articulated methodology developed by the High Court that is principled, transparent and logically consistent with the purpose of the provision. This is contrasted with two recent decisions of the High Court, ICM Agriculture Pty Ltd v Commonwealth and Phonographic Performance Company of Australia Ltd v Commonwealth which indicate a concerning development to move away from such methodology and introduce new factors for consideration. It is argued that such development threatens to undermine the principled and transparent application of s 51(xxxi) and may reintroduce unnecessary methodological uncertainty.

Expressão imuno-histoquímica das integrinas α2ß1, α3ß1, e α5ß1, em mucosa oral normal, hiperplasia fibroepitelial inflamatória oral e displasia epitelial oral

The objective of this study was perform by the streptoavidin-biotin technique an immunohistochemical analysis of α2β1, α3β1e α5β1 integrins in 11 normal oral mucosa (NOM), 16 oral inflammatory fibroepithelial hyperplasia (OIFH) and 25 oral epithelial dysplasia (OED) (16 mild, 2 moderates and 7 severe), to determine if exists qualitative alteration in the expression of these integrins and if this guard relation with the oral epithelial modifications. It was observed that for the α2β1 integrin the majority of the sample showed a predominantly intense labeling diffusely distributed in the intercellular contacts and the cytoplasm of cells of the basal and suprabasal layers, without difference of this profile between the different types of specimens, however with a trend to weak or loss of expression in 21.1% of the OEDs, being all the specimens that had not expressed this heterodimer, severe OEDs. For the α3β1 integrin the majority of the sample showed a weak or absent labeling in basal layer. The α5β1 integrin showed a predominant strong diffuse labeling in the intercellular contacts and cytoplasm in the suprabasal layer, with difference only in the labeling intensity between the types of specimens, inhabiting this difference in the OEDs, where 12 (48%) specimens had shown a weak labeling. It was concluded that the evaluated integrins can be involved in the cell-cell, cell-ECM interactions modulating the cellular differentiation and maintenance of the epithelial structural arrangement. The variable expression of the α5β1 integrin in the OEDs, could suggest, respectively, a role of this molecule in the cellular survival, with intention to perpetuate the modified phenotype in these lesions, or a suppressor role on the modified phenotype due to lack of interaction of this molecule with the fibronectina of the MEC

Expressão imuno-histoquímica das integrinas α2ß1, α3ß, e α5ß1, em carcinoma epidermóide de lábio inferior e língua

The unpredictable biologic behavior of the oral squamous cells carcinoma has determined extensive research on the evolution of such tumor. Due to the existing relation between the outer cell matrix and the tumor cells, the integrins have been used as markers in the predictive study of the cell behavior. This study aims to analyze immunohistochemically the expression of the integrin α2β1, α3β1, and α5β1 connections for the collagen, the laminin and the fibronectin respectively in 15 cases of squamous cells carcinoma from the lower lip and 15 from the tongue, with different scores of malignance grading. A predominantly diffuse, cytoplasm and granular immunological marking was observed in the majority of the analyzed cases. According to the marking intensity, integrin α2β1 appeared positive in 80% of the lip and in 93,3% of the tongue cases. The immunological reactivity of integrin α3β1 was classified as positive in 60% of both the tongue and lip cases. For this integrin, 20% and 33.3% of the tongue and lip cases, respectively, were negative. In relation to integrin α5β1 the intensity was classified as positive in 53,3% of the cases and strongly positive in 46,7% of those located in the lip. In the tongue carcinomas, the intensity was positive in 46,7% of the cases and strongly positive in 53,3%. The statistic analysis did not show any significant differences or correlation of expression between these integrins nor between the anatomical sites or between different scores of malignancy grading. The expressive immunological marking of the integrins, α2β1, α3β1, and α5β1 in the studied cases of squamous cell carcinomas leads us to think of a great participation of these proteins in oral carcinogenesis; however, our results do not allow us to correlate its expression as an indicator of variations in the biological behavior of this neoplasia

Leite cru de quatro regiões leiteiras brasileiras: perspectivas de atendimento dos requisitos microbiológicos estabelecidos pela Instrução Normativa 51

Evidências que o leite produzido e consumido no Brasil nem sempre apresenta a qualidade desejada têm gerado a discussão e desenvolvimento de novas políticas de incentivo à produção leiteira, resultando no desenvolvimento do Programa Nacional de Melhoria da Qualidade do Leite. em complementação, em 2002 o Ministério da Agricultura publicou a Instrução Normativa 51 (IN51), com importantes inovações em relação à conservação e transporte do leite cru, além de estabelecimento de um padrão de qualidade para esse tipo de leite (10(6) UFC/mL), a ser implantado em diferentes prazos nas diferentes regiões do país, a partir de 2005. O presente trabalho teve como objetivo verificar se o leite cru produzido em quatro áreas de quatro estados produtores de leite no Brasil estaria, nesse momento, em condições de cumprir o estabelecido na IN 51, especialmente quanto ao atendimento dos padrões microbiológicos previstos. Amostras de leite cru, coletadas em 210 diferentes propriedades nas regiões de Viçosa, MG (47), Pelotas, RS (50), Londrina, PR (63) e Botucatu, SP (50), foram analisadas quanto aos níveis de contaminação por aeróbios mesófilos, utilizando o PetrifilmTM AC. Parcela significativa das amostras (48,6%) apresentaram contagens acima do determinado pela IN51, sendo 21,3% na região de Viçosa (MG), 56,0% na região de Pelotas (RS), 47,6% na região de Londrina (PR) e 68,0% na região de Botucatu (SP). Considerando as diferenças de cada região, foi possível observar a importância da refrigeração na conservação e transporte da produção, bem como da implantação de boas práticas e assistência técnica nas propriedades. Os resultados obtidos permitem concluir que a adequação às normas estabelecidas pela IN51 pode ser mais difícil em algumas regiões do que em outras, sendo fundamental a adoção da refrigeração na conservação e no transporte da produção, e de programas regionais de assistência a produtores leiteiros.

Comparative anatomy of the male reproductive internal organs of 51 species of bees

A anatomia dos órgãos internos do aparelho reprodutor de machos (ARM) adultos e pupas foi comparada em 51 espécies de abelhas, incluindo representantes de seis famílias. Foram obtidos quatro tipos diferentes de ARM. O tipo I está presente em machos das famílias mais basais (Colletidae, Andrenidae e Halictidae) e é caracterizado por três túbulos seminíferos por testículo, o qual é quase totalmente envolvido pela membrana escrotal. O tipo II é um tipo intermediário entre os tipos I e III e está presente em Mellitidae e Megachilidae, como também em alguns Apidae estudados, sendo caracterizado por possuir dutos deferentes pós-vesiculares fora da membrana escrotal e possuir três ou quatro túbulos seminíferos por testículo, exceto Apis mellifera L., a qual possui secundariamente um número aumentado de túbulos. O tipo III foi achado somente nos Apidae estudados e é caracterizado por apresentar os testículos e dutos genitais (exceto o duto deferente pós-vesicular) encapsulados separadamente, as glândulas acessórias são bem desenvolvidas e o duto ejaculador é calibroso, apresentando fissuras em sua parede externa, as quais podem ocorrer também no tipo II. O tipo IV está presente exclusivamente na tribo Meliponini e é caracterizado pela ausência de glândulas acessórias.
