Historic concrete buildings are at risk. Limited knowledge of concrete technology until the 1960s led to more sensitive buildings than modern concrete buildings. In addition, the lack of sensibility regarding their heritage value and insufficient protection is leading to remorseless demolition. Still, concrete has proved to be a resilient material that can last over a century with proper care. There is not yet an estimation of the status of historic concrete buildings in Europe. Until now, a few attempts have been done to secondarily, and subjectively, gauge their conservation status. This paper is the result of a joint investigation studying forty-eight historic concrete buildings distributed in four countries. They were surveyed by expert teams according to a predefined methodology. The study aims to identify recurrent damages and parameters affecting the conservation state. It also aims to serve as the first trial for an objective and measurable methodology, to apply it with a statistically significant number of cases. Damages related to the corrosion of reinforcement and moisture-related processes were the most recurrent. The use of plasters, flat roofs, and structural façade walls show a positive effect in protecting the concrete. The state of conservation has a great variability across countries.

Politics and the life sciences—also referred to as biopolitics—is a field of study that seeks to advance knowledge of politics and promote better policymaking through multidisciplinary analysis that draws on the life sciences. While the intellectual origins of the field may be traced at least into the 1960s, a broadly organized movement appeared only with the founding of the Association for Politics and the Life Sciences (APLS) in 1980 and the establishment of its journal,Politics and the Life Sciences(PLS), in 1982. This essay—contributed by a past journal editor and association executive director—concludes a celebration of the association's thirtieth anniversary. It reviews the founding of the field and the association, as well as the contributions of the founders. It also discusses the nature of the empirical work that will advance the field, makes recommendations regarding the identity and future of the association, and assesses the status of the revolution of which the association is a part. It argues that there is progress to celebrate, but that this revolution—the last of three great scientific revolutions—is still in its early stages. The revolution is well-started, but remains unfinished.

Since the mid 1930's there has been an accelerating growth in understanding the nature and scope of alcohol abuse, and a modest increase in resources to combat it. Although, as early as 1869, a significant court decision held that alcoholism could be viewed as an illness, It was not until the second half of the 1960s that the next such findings, this time by Federal courts, set the course of continuing action to take alcoholism out of the criminal justice system and place it under the aegis of health care. The status of alcoholism legislation in thirty-eight states is examined, based on their resonse to a survey questionnaire and other data provided by the National Institute on Alcohol Abuse and Alcoholism. Alternate treatment systems, developed and tested by the Ontario Addictions Foundation, provide background to the treatment systems which have emerged in most states which have decriminalized public intoxication.

Abstract The aim of this study was to identify the role of field margin habitats in preserving the diversity and abundance of ground beetle assemblages, including potentially entomophagous species and those with conservation status in Poland. Research material was collected in 2006–2007 in four types of margin habitats – a forest, bushes, ditches and in two arable fields. Insects were captured into pitfalls, without preservation liquid or bait added to the traps. Traps were inspected twice a week, between May and August, and one sample was a weekly capture. In field margin habitats the most abundant species were Limodromus assimilis, Anchomenus dorsalis, Pterostichus melanarius and Carabus auratus. A lower abundance of species was noted on fields, with dominant Poecilus cupreus and P. melanarius. The group of zoophagous carabids found in our study includes 30 species from field margin habitats, i.e. 37.5% of all captured Carabidae taxa and 58.3% of all specimens. The share of aphidophagous species was 84.9% among bushes, 86.7% near ditches, and 88.0% in the forest habitat. Several species captured during the study are under protection in Poland. These include the partly protected Carabus convexus, which also has the status of near threatened species, the partly protected Calosoma auropunctatum, and Broscus cephalotes. Considering all the investigated field margin habitats, ground beetles were most numerous in the oak-hornbeam habitat, defined as bushes, formed predominantly by Prunus spinosa, Crataegus leavigata, Sambucus nigra and Rosa canina. Thus, this habitat was the most important reservoir/refugium for the ground beetles.

A partir da década de 1960 teve início na Europa e nos EUA um novo movimento artístico conhecido como arte performativa. ORLAN, artista plástica francesa, insere-se neste movimento através de obras que incluem intervenções cirúrgicas em seu próprio corpo com o objetivo de questionar o status do corpo feminino na sociedade ocidental contemporânea. Diante disso, propomos no presente artigo, uma análise do seu trabalho a partir das considerações teóricas do filósofo e escritor transgênero Paul B. Preciado.Palavras-chave: Arte performativa; ORLAN; Gênero; Feminismo; Paul. B. Preciado.AbstractFrom the 1960s, a new artistic movement known as performative art began in Europe and the USA. ORLAN, a French artist, is part of this movement through works that include surgical interventions on her own body in order to question the status of the female body in contemporary Western society. Therefore, in this article, we propose an analysis of his work based on the theoretical considerations of the transgender philosopher and writer Paul B. Preciado.Keywords: Performative art; ORLAN; Genre; Feminism; Paul B. Preciado.

The aim of the study was to evaluate the elevated temperature on germination and seedling growth and the ameliorative effect of silicon on the phenolic compounds of black-eyed cowpea. The seeds were allowed to germinate at 30 (control), 36 and 44°C temperatures, under controlled conditions, silicons were with concentrations of 0.0 (control) and 1.5 mM. In the second phase of the experiment, some of the seeds were grown in plastic cups with sieved soil at 30 °C, 36 °C and 44 °C for phenolic compounds. Among the temperature treatments, plant deaths occurred at 44 °C. The raise in temperature importantly reduced germination and related traits. Except for SL, the seeds showed good germination at 30 °C after Si application. In high temperatures, silicon applications had a positive effect on germination and seedling growth, except for the germination rate. Results showed that an increase in GA, PA, Q, CAM, CA, PCA, SA, VA, CAF as temperatures increased. But chlorogenic acid and Q values were higher at 30 °C. This study clearly observed that the growth of cowpea seedlings decreased with temperature increase, but silicon attenuated these effects.

The article describes the origins, evolution and status of Sotho1 koriana accordion music from the 1920s through the 1960s and 70s when it was considered shebeen music, and from1980 to 2005, when there was a change of attitude towards it and only sporadic production. Two concerns are: the status of koriana music, and, its appreciation by Sotho people themselves. Data was collected through observations, interviews with artists and listeners, and from cassettes, radio and TV programmes. Aspects of the music are described and related to non-musical events of the period.

Its primary purpose is to present the reception of the discussion between positivism and narrativism in the Polish methodology of history. A secondary one is to paraphrase, using the notion apparatus of the idealisational theory of science, the issue of the accuracy of explanation. The article consists of six parts. In the first part, Hempel’s deductive-nomological (or covering-law) model of explanation is presented. In the second part, the main tenets and assumptions of the Poznań school of methodology are presented. The emergence of this school at the end of the 1960s delayed the popularisation of narrativism in Polish methodology of history. In the third part, the manifold reasons of this delayed reception are analysed. The popularization of narrativism was only possible in Poland after 1989, but it had a primarily imitative character. This outline of cultural and scientific context allows Chris Lorenz’s proposals (on the problem of the accuracy of explanation) to be put in a wider perspective (part four). Namely, this author describes “a theoretical historical debate” on the status of scientific laws and refers to a post-positivistic approach to science represented by Nancy Cartwright. This approach was to introduce new perspectives to the understanding of lawfulness. In the fifth part, the main assumptions and tenets (for example, modes of explanation) of another post-positivistic approach to science, namely the idealisational theory of science, are presented and compared with the Hempelian model of explanation. In the sixth part, Hempel’s explanatory sketch is paraphrased using the notion apparatus of the idealisational model of science which provides a solution in this theoretical framework, to the problem of accuracy of explanation posed by Lorenz.</p> <!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" LatentStyleCount="156"> </w:LatentStyles> </xml><![endif]--><!--[if !mso]><object classid="clsid:38481807-CA0E-42D2-BF39-B33AF135CC4D" id=ieooui></object> <mce:style><! st1\:*{behavior:url(#ieooui) } --> <!--[endif] --><!--[if gte mso 10]> <mce:style><! /* Style Definitions */ table.MsoNormalTable {mso-style-name:Standardowy; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} --> <!--[endif] -->

The substitution of high-value fish species for those of lower value is common practice. Although numerous studies have addressed this issue, few have been conducted in Mexico. In this study, we sought to identify fresh fillets of fish, sharks, and rays using DNA barcodes. We analyzed material from “La Viga” in Mexico City, and other markets located on the Gulf and Caribbean coasts of Mexico. From 134 samples, we obtained sequences from 129, identified to 9 orders, 28 families, 38 genera, and 44 species. The most common species were Seriola dumerili, Pangasianodon hypophthalmus, Carcharhinus falciformis, Carcharhinus brevipinna, and Hypanus americanus. Pangasianodon hypophthalmus was most commonly used as a substitute for higher-value species. The substitution rate was 18% of the total. A review of the conservation status of the specimens identified against the IUNC list enabled us to establish that some species marketed in Mexico are threatened: Makaira nigricans, Lachnolaimus maximus, Hyporthodus flavolimbatus, and Isurus oxyrinchus are classified as vulnerable; Lopholatilus chamaeleonticeps and Sphyrna lewini are endangered; and the status of Hyporthodus nigritus is critical. These results will demonstrate to the Mexican authorities that DNA barcoding is a reliable tool for species identification, even when morphological identification is difficult or impossible.


<em>Abstract</em>.—There are 11 lamprey species in Canada: Vancouver lamprey <em>Entosphenus macrostomus</em> (formerly <em>Lampetra macrostoma</em>), Pacific lamprey <em>Entosphenus tridentatus</em> (formerly <em>Lampetra tridentata</em>), chestnut lamprey <em>Ichthyomyzon castaneus</em>, northern brook lamprey <em>Ichthyomyzon fossor</em>, silver lamprey <em>Ichthtyomyzon unicuspis</em>, river lamprey <em>Lampetra ayresii</em>, western brook lamprey <em>Lampetra richardsoni</em>, Alaskan brook lamprey <em>Lethenteron alaskense</em>, American brook lamprey <em>Lethenteron appendix</em> (formerly <em>Lampetra appendix</em>), Arctic lamprey <em>Lethenteron camtschaticum</em> (formerly <em>Lampetra camtschatica</em>), and sea lamprey <em>Petromyzon marinus</em>. <em>Entosphenus</em> and <em>Lethenteron</em> were previously synonymized with <em>Lampetra</em>, but Nelson (2006) recognized these as three distinct genera. Conservation status has been assessed in only five species and in two of these (western brook lamprey and chestnut lamprey), only for portions of their Canadian population. The 2007 Committee on the Status of Endangered Wildlife in Canada list indicates that the enigmatic population of western brook lamprey in Morrison Creek, British Columbia, is endangered; the Vancouver lamprey in British Columbia is threatened; the chestnut lamprey in Saskatchewan and Manitoba is special concern; the northern brook lamprey in Manitoba, Ontario, and Quebec is of special concern in the latter two provinces and data deficient in the former; and the Alaskan brook lamprey in the Northwest Territories is data deficient. The threats to the four species at risk were collectively related to habitat degradation and loss, sensitivity to a catastrophic event, and sensitivity to lampricide used to control the invasive sea lamprey in the Great Lakes basin. Despite much lamprey work being conducted in the past decade, there still remain a number of knowledge gaps. These gaps include unequivocal evidence as to whether parasitic and nonparasitic members of a paired species should be considered distinct species and information on the distribution and population sizes and trends of the native lamprey species.

Chapter five focuses on the development of youth welfare work, in particular the youth club, as a response to concerns that young people were not using their leisure time appropriately. Fred Powell, Martin Geoghegan, Margaret Scanlon and Katharina Swirak highlight how an international volunteer boom in the 1960s, and in the field of youth work in particular, in part reflected changing attitudes to youth and concerns about what seemed a disaffected generation. This chapter assesses developments in youth work at a local and national level, highlighting the impact of international strategies in this field and the tensions between the many players in the Irish scene. It attests to the ways in which external frameworks, emanating from supranational bodies such as the Council of Europe and the United Nations, reframed understandings of youth in the adult imagination and influenced how youth was perceived by voluntary and statutory organisations. It also highlights the ways in which some international ideas and models were embraced but others challenged the status quo, and therefore faced resistance.
