Climate and construction delays: case study in Chile

Purpose – Construction projects usually suffer delays, and the causes of these delays and its cost overruns have been widely discussed, the weather being one of the most recurrent. The purpose of this paper is to analyze the influence of climate on standard construction work activities through a case study. Design/methodology/approach – By studying the extent at which some weather variables impede outdoor work from being effectively executed, new maps and tables for planning for delays are presented. In addition, a real case regarding the construction of several bridges in southern Chile is analyzed. Findings – Few studies have thoroughly addressed the influences of major climatic agents on the most common outdoor construction activities. The method detailed here provides a first approximation for construction planners to assess to what extent construction productivity will be influenced by the climate. Research limitations/implications – Although this study was performed in Chile, the simplified method proposed is entirely transferable to any other country, however, other weather or combinations of weather variables could be needed in other environments or countries. Practical implications – The implications will help reducing the negative social, economic and environmental outcomes that usually emerge from project delays. Originality/value – Climatic data were processed using extremely simple calculations to create a series of quantitative maps and tables that would be useful for any construction planner to decide the best moment of the year to start a project and, if possible, where to build it.

Anticipatory governance for social-ecological resilience

Anticipation is increasingly central to urgent contemporary debates, from climate change to the global economic crisis. Anticipatory practices are coming to the forefront of political, organizational, and citizens’ society. Research into anticipation, however, has not kept pace with public demand for insights into anticipatory practices, their risks and uses. Where research exists, it is deeply fragmented. This paper seeks to identify how anticipation is defined and understood in the literature and to explore the role of anticipatory practice to address individual, social, and global challenges. We use a resilience lens to examine these questions. We illustrate how varying forms of anticipatory governance are enhanced by multi-scale regional networks and technologies and by the agency of individuals, drawing from an empirical case study on regional water governance of Mälaren, Sweden. Finally, we discuss how an anticipatory approach can inform adaptive institutions, decision making, strategy formation, and societal resilience.

An assessment of the effects of climate change on horticulture

Horticulture may be defined as the intensive cultivation and harvesting of plants for financial, environmental and social profit. Evidence for the occurrence of climate change more generally and reasons why this process is happening with such rapidity are discussed. These changes are then considered in terms of the effects which might alter the options for worldwide intensive horticultural cultivation of plants and its interactions with other organisms. Potentially changing climates will have considerable impact upon horticultural processes and productivity across the globe . Climate change will alter the growth patterns and capabilities for flowering and fruiting of many perennial and annual horticultural plants. In some regions perennial fruit crops are likely to experience substantial difficulties because of altered seasonal conditions affecting dormancy, acclimation and subsequent flowering and fruiting. Elsewhere these crops may benefit from the effects of climate change as a result of reduced cold damage and increased length of the growing season. There will be considerable effects for aerial and edaphic microbes invertebrate and vertebrate animals which have benign and pathogenic interactions with horticultural plants. Microbial activity and as a consequence soil fertility may alter. New pests and pathogens may become prevalent and damaging in areas where the climate previously excluded their activity. Vital resources such as water and nutrients may become scarce in some regions reducing opportunities for growing horticultural crops. Wind and windiness are significant factors governing the success of horticultural plants and the scale of their impacts may change as climate alters. Damaging winds could limit crop growing in areas where previously it flourished. Forms of macro- and micro-landscaping will change as the spectrum of plants which can be cultivated alters and the availability of resources and their cost changes driven by scarcities brought about by climate change. The horticultural economy of India as it may be affected by climate change is described as an individual example in a detailed study.

Environmentalities of urban climate governance in Maputo, Mozambique

Interest in the role that cities can play in climate change as sites of transformation has increased but research has been limited in its practical applications and there has been limited consideration of how policies and technologies play out. These challenges necessitate a re-thinking of existing notions of urban governance in order to account for the practices that emerge from governments and a plethora of other actors in the context of uncertainty. We understand these practices to constitute adaptive governance, underpinned by social learning guiding the actions of the multiplicity of actors. The aim here is to unpack how social learning for adaptive governance requires attention to competing understandings of risk and identity, and the multiplicity of mechanisms in which change occurs or is blocked in urban climate governance. We adopt a novel lens of 'environmentalities' which allows us to assess the historical and institutional context and power relations in the informal settlements of Maputo, Mozambique. Our findings highlight how environmental identities around urban adaptation to climate change are constituted in the social and physical divisions between the formal and informal settlements, whilst existing knowledge models prioritise dominant economic and political interests and lead to the construction of new environmental subjects. While the findings of this study are contextually distinct, the generalizable lessons are that governance of urban adaptation occurs and is solidified within a complex multiplicity of socioecological relations.

Doing well by talking good? A topic modelling-assisted discourse study of corporate social responsibility

Using the novel technique of topic modelling, this paper examines thematic patterns and their changes over time in a large corpus of corporate social responsibility (CSR) reports produced in the oil sector. Whereas previous research on corporate communications has been small-scale or interested in selected lexical aspects and thematic categories identified ex ante, our approach allows for thematic patterns to emerge from the data. The analysis reveals a number of major trends and topic shifts pointing to changing practices of CSR. Nowadays ‘people’, ‘communities’ and ‘rights’ seem to be given more prominence, whereas ‘environmental protection’ appears to be less relevant. Using more established corpus-based methods, we subsequently explore two top phrases - ‘human rights’ and ‘climate change’ that were identified as representative of the shifting thematic patterns. Our approach strikes a balance between the purely quantitative and qualitative methodologies and offers applied linguists new ways of exploring discourse in large collections of texts.

Climate change and energy use : The role for anthropological research

The expression 'global climate change' no longer designates merely a discourse on possible future risks; today it us used as a shorthand for specific ongoing events that are having a serious impact on the lives of people around the world. In the light of this change and consequent efforts to limit carbon dioxide emissions, contributions from social scientists are increasingly in demand within the study of energy use. My concern here is not whether intervention is a proper role for anthropologists, but rather how we may position ourselves within energy- and climate-related research.

Responsabilidade social sob a ótica do assédio moral: o caso furnas

The objectives of this research were to identify and to determine the mam elements presents in actions developed by the company classified as corporate social responsibility as well as the company's speech and relation with their employees1 in Fumas' productive units. In the base theoretician-empiricist, were analyzed the aspects concerning to the social management considering the postindustrial societal model, as to the social responsibility and the moral siege aspect present in the internaI company' s relations. The method that characterizes this research is the case study of a mixing economy company considered as prominence in the industrial scene of the country, from the verification of its organizational climate. The data had been gotten by direct comment and by semistructuralized interviews, carried through with workers belonging to diverse hierarchic organization's studied leveIs, involved with social practices and their organization, having relationship to the employees. The analysis was description-qualitative formo The collected data disclose to the existence of accords and dissonances between the social responsibility practical, the moral siege and the speech presented by this company. The main objective of the study was to extend the agreement concerning to the social responsibility, as well as the moral siege practiced by the company, having as reference their integrant's perceptions, considering both the current economic and social rationalities that establish a new mo dei of relationship between State, companies under its protection and the civil society.

Influência de um programa de intervenção motora inclusiva no desenvolvimento motor e social de crianças com atrasos motores

O objetivo desta pesquisa, de delineamento quase-experimental, foi verificar a influência de um Programa de Intervenção Motora Inclusiva (PIMI) no desenvolvimento motor (DM) e social (DS) de crianças, portadoras (PNEE) e não portadoras de necessidades educacionais especiais (n-PNEE), com atrasos motores. A amostra desta pesquisa foi não probabilística, intencional, composta por 76 crianças (43 meninos e 33 meninas), com idades de 4 a 10 anos (M=7,00, DP=1,44), sendo 24 (31,6%) crianças PNEE e 52 (68,4%) crianças n-PNEE, que apresentaram desempenho motores inferiores a seus pares, configurando atrasos motores, avaliados por meio do Test of Gross Motor Development- 2 (TGMD-2) (ULRICH, 2000). Trinta e cinco crianças constituíram o Grupo de Intervenção (GI) e quarenta e uma crianças constituíram o Grupo Controle (GC). Para a avaliação do DM das crianças dos grupos foi utilizado o TGMD-2 e para a avaliação do DS das crianças do GI foi utilizado a estrutura de Níveis de Responsabilidade Social e Pessoal (HELLISON, 2003). O PIMI foi desenvolvido em 14 semanas, implementando os princípios do Contexto Motivacional para a Maestria e os pressupostos da estrutura TARGET. General Linear Model com medidas repetidas no fator tempo foi conduzida para avaliar os efeitos do PIMI no DM das crianças. Para a análise do DS foi utilizado o teste de Friedman. Os resultados indicaram que (1) crianças, PNEE e n- PNEE, do GI demonstraram ganhos significantes em habilidades de locomoção e de controle de objeto do pré-teste para o pós-teste, enquanto que para as crianças, PNEE e n-PNEE, do GC mudanças significativas não foram encontradas, (2) crianças, PNEE e n-PNEE, do GI demonstraram desempenho significantemente superior em habilidades de locomoção e de controle de objeto comparadas as crianças, PNEE e n-PNEE, do GC no pós-teste, (3) crianças PNEE, do GI, demonstraram padrões de mudanças positivas e significativas do pré-teste para o pós-teste nas habilidades de locomoção e de controle de objeto semelhantes aos seus pares n-PNE do mesmo grupo, (4) crianças PNEE, do GI, demonstraram no pós-teste desempenho significantemente superior nas habilidades de locomoção e controle de objetos comparadas aos seus pares PNEE do GC, (5) crianças n-PNEE, do GI, demonstraram no pós-teste desempenho significantemente superior nas habilidades de locomoção e de controle de objeto comparadas aos seus pares n-PNEE do GC, (6) crianças, PNEE e n-PNEE, do GI, demonstraram mudanças positivas e significativas no DS no contexto de aprendizagem por meio da conquista de níveis de responsabilidade social e pessoal mais elevados, no decorrer do PIMI, (7) crianças PNEE, do GI, demonstraram padrões de mudanças positivas e significativas no DS semelhantes aos seus pares n-PNEE do mesmo grupo. E mais, a implementação do Contexto Motivacional para a Maestria possibilitou a participação cooperativa e efetiva de todas as crianças indiferentemente dos níveis de habilidade motora.

Comparison and analysis of corporate social responsibility (CSR) reports of the top five companies ranked on the 2013 CSR RepTrak

In the 1970s, Corporate Social Responsibility (CSR) was discussed by Nobel laureate Milton Friedman in his article “The Social Responsibility of Business Is to Increase Its Profits.” (Friedman, 1970). His view on CSR was contemptuous as he referred to it as “hypocritical window-dressing” a reflection of the view of Corporate America on CSR back then. For a long time short-term maximization of shareholder value was the only maxim for top management across industries and companies. Over the last decade, CSR has become a more important and relevant factor of a company’s reputation, shifting the discussion from whether CSR is necessary to how best CSR commitments should be done (Smith, 2003). Inevitably, companies do have an environmental, social and economic impact, thereby imposing social costs on current and future generations. In 2013, 50 of the world biggest companies have been responsible for 73 percent of the total carbon dioxide (CO2) emission (Global 500 Climate Change Report 2013). Post et al. (2002) refer to these social costs as a company’s need to retain its “license to operate”. In the late 1990s, CSR reporting was nearly unknown, which drastically changed during the last decade. Allen White, co-founder of the Global Reporting Initiative (GRI), said that CSR reporting”… has evolved from the extraordinary to the exceptional to the expected” (Confino, 2013). In confirmation of this, virtually all of the world’s largest 250 companies report on CSR (93%) and reporting by now appears to be business standard (KPMG, 2013). CSR reports are a medium for transparency which may lead to an improved company reputation (Noked, 2013; Thorne et al, 2008; Wilburn and Wilburn, 2013). In addition, it may be used as part of an ongoing shareholder relations campaign, which may prevent shareholders from submitting Environmental and Social (E&S)1 proposals (Noked, 2013), based on an Ernst & Young report 1 The top five E&S proposal topic areas in 2013 were: 1. Political spending/ lobbying; 2. Environmental sustainability; 3. Corporate diversity/ EEO; 4.Labor/ human rights and 5. Animal testing/ animal welfare. Three groups of environmental sustainability proposal topics of sub-category number two (environmental sustainability) 6 2013, representing the largest category of shareholder proposals submitted. PricewaterhouseCoopers (PwC) even goes as far as to claim that CSR reports are “…becoming critical to a company’s credibility, transparency and endurance.” (PwC, 2013).

Utilização de um aplicativo de simulação computacional na avaliação de desempenho térmico de protótipo de habitação de interesse social (his)

This Masters Degree dissertation seeks to make a comparative study of internal air temperature data, simulated through the thermal computer application DesignBuilder 1.2, and data registered in loco through HOBO® Temp Data Logger, in a Social Housing Prototype (HIS), located at the Central Campus of the Federal University of Rio Grande do Norte UFRN. The prototype was designed and built seeking strategies of thermal comfort recommended for the local climate where the study was carried out, and built with panels of cellular concrete by Construtora DoisA, a collaborator of research project REPESC Rede de Pesquisa em Eficiência Energética de Sistemas Construtivos (Research Network on Energy Efficiency of Construction Systems), an integral part of Habitare program. The methodology employed carefully examined the problem, reviewed the bibliography, analyzing the major aspects related to computer simulations for thermal performance of buildings, such as climate characterization of the region under study and users thermal comfort demands. The DesignBuilder 1.2 computer application was used as a simulation tool, and theoretical alterations were carried out in the prototype, then they were compared with the parameters of thermal comfort adopted, based on the area s current technical literature. Analyses of the comparative studies were performed through graphical outputs for a better understanding of air temperature amplitudes and thermal comfort conditions. The data used for the characterization of external air temperature were obtained from the Test Reference Year (TRY), defined for the study area (Natal-RN). Thus the author also performed comparative studies for TRY data registered in the years 2006, 2007 and 2008, at weather station Davis Precision Station, located at the Instituto Nacional de Pesquisas Espaciais INPE-CRN (National Institute of Space Research), in a neighboring area of UFRN s Central Campus. The conclusions observed from the comparative studies performed among computer simulations, and the local records obtained from the studied prototype, point out that the simulations performed in naturally ventilated buildings is quite a complex task, due to the applications limitations, mainly owed to the complexity of air flow phenomena, the influence of comfort conditions in the surrounding areas and climate records. Lastly, regarding the use of the application DesignBuilder 1.2 in the present study, one may conclude that it is a good tool for computer simulations. However, it needs some adjustments to improve reliability in its use. There is a need for continued research, considering the dedication of users to the prototype, as well as the thermal charges of the equipment, in order to check sensitivity

O Serviço Social nas operadoras de planos privados de assistência à saúde: demandas, atribuições e respostas profissionais

The present study deals with the exercise of professional social workers in private health care plans registered with the Regional Council of Medicine/RN, in the city of Natal/RN, with regards to the demands/tasks, work conditions, and the professional response, given the climate of restructuring the capital. The set of socio-historical transformations, as a results of the dynamic capitalist, is a process of new configurations in relation to state and society that interfere directly in relation to working conditions, social rights historically won by workers. In this context, the operator of health plans arises as a possibilities to provide services in health, through the logic of the market, in which the subjects of law, become consumers contributing to the displacement of the responsibilities of the State. Obligating workers to lessen the burden with the reproduction of their workforce. This involves changing societal context for social service, since it is one of the professions that are active in terms of the immediate social issue, and come as part of the collective worker. From qualitative research based on a theoretical and methodological perspective and critical dialectics, it was possible to unveil some features and trends of the exercise of(a) social operators in private health care plans. The survey results indicated that : a) the demands and duties for certain social service, are associated with the redevelopment of the capital, whose requirements and responsibilities professionals have with their needs, particularly the guarantee of profit, services rendered; b) in the conditions of work there is a trend of insecurity uncertainty and dismantling of professionals; c) the answers professionals suffer the limits and contradictions present in the daily training, mainly depending one the characteristics of management and operation of the operators, which has professional relative autonomy

Polybitoxins: A group of phospholipases A2 from the venom of the neotropical social wasp paulistinha (Polybia paulista)

The neotropical wasp Polybia paulista is very aggressive and endemic in south-east Brazil, where it frequently causes stinging accidents. By using gel filtration on Sephadex G-200, followed by ion-exchange chromatography on DEAE-Cellulose under a pH gradient, a group of four toxins (designated as polybitoxins-I, II, lII and IV) presenting phospholipase A2 (PLA2) activities was purified. These toxins are dimeric with mol. wts ranging from 115,000 to 132,000 and formed by different subunits. The four toxins contain very high sugar contents attached to their molecules (22-43% w/w) and presented different values of pH optimum from 7.8 to 9.0; when dissociated, only residual catalytic activities were maintained. The catalytic activities of polybitoxins (from 18 to 771 μmoles/mg per minute) are lower than that of PLA2 from Apis mellifera venom and hornetin from Vespa basalis. The polybitoxins presented a non-linear steady-state kinetic behavior for the hydrolysis of phosphatidylcholine at pH 7.9, compatible with the negative co- operativity phenomena. All of the polybitoxins were very potent direct hemolysins, especially the polybitoxins-III and IV, which are as potent as the lethal toxin from V. basalis and hornetin from Vespa flavitarsus, respectively; polybitoxin-IV presented hemolytic action 20 times higher than that of PLA2 from A. mellifera, 17 times higher than that of neutral PLA2 from Naja nigricolis and about 37 times higher than that of cardiotoxin from Naja naja atra venom.
