Abstract Adobe is an old material used in construction but over time, this construction system has lost space and preference among population. Hence, the need to seek alternatives as professionals in the construction area to encourage the use of the Adobe technique has raised. Thus, the present study made a cost of the items involved in the construction of houses from the adobe based on the theoretical references. In addition, it established a unit price analysis that identifies the particularities of this system focusing on an analytical, descriptive-conclusive methodology whose data are analysed from the results of applying a survey (n = 96) to the inhabitants of the rural sector of Cuenca and construction experts (n = 11). The average price of the construction of houses with Adobe is $ 38,357.23 dollars for a house of 150 m2 taking into account that the real costs and the construction activity are sensitive to changes in the population and market prices.

Abstract The tapial is part of the traditional construction worldwide, which uses environmentally friendly materials of natural origin such as raw earth, wood and water for its manufacture. The construction technique was used for the construction of habitable spaces, which are part of the ancestral construction system of our country; Despite the above, no updated studies on the costs required in the construction process have been identified in Ecuador. This is mainly due to the constant development of new technologies that introduce new construction systems to the market that use industrialized materials for their manufacture. Therefore, this document evaluated and analyzed the unit prices of the items involved in the construction of works using mud as its main component. Field and exploratory research was applied, through the application of surveys to a sample of 97 professionals of Civil Engineering and Architecture in the city of Cuenca, as well as 30 professionals with experience in construction of the indicated construction system. The Unit Price Analysis determined that the average cost of a 140 m2 typical house is $ 46,236.64 with an estimated cost of $ 330.26 per square meter; Similarly, the study determined a maximum cost of $ 53,172.14 USD with a value of $ 379.80 USD per square meter and a minimum value that represents $ 39,301.14 with a cost per square meter of $ 280.72.

Abstract The bahareque is a form of vernacular construction that, with the help of modern materials with adequate techniques and knowledge, constitute an alternative to provide housing solutions. Despite this, the lack of knowledge and technical processes in relation to costs, gives rise to a research problem. Thus, this document presents a set of technical strategies based on the Cost-Benefit analysis of using bahareque as a raw material and structuring a unit price analysis tool to guide construction professionals. The study had a qualitative and quantitative approach, surveys were applied to the population and professionals in the construction area that allowed to approach the reality of the construction system in the city of Cuenca-Ecuador. It is evident that people know about the construction system, but show some resistance to its application because they are unaware of the advantages and disadvantages of the vernacular technique. With the cost analyzes carried out, it is concluded that a typical house of 130 m2 has a cost of $ 36,387.72 dollars; which, starts from concrete foundations, which support a reinforced masonry assembly that raises the wooden frames, associated with meshes that erect the walls with mortar and finally covered with roofs with a mixed material of wood and tile fired with clay.

Background: In light of the few reports from intertropical latitudes and their conflicting results, we aimed to replicate and update the investigation of seasonal patterns of suicide occurrences in the city of São Paulo, Brazil. Methods: Data relating to male and female suicides were extracted from the Mortality Information Enhancement Program (PRO-AIM), the official health statistics of the municipality of São Paulo. Seasonality was assessed by studying distribution of suicides over time using cosinor analyses. Results: There were 6,916 registered suicides (76.7% men), with an average of 39.0 ± 7.0 observed suicides per month. For the total sample and for both sexes, cosinor analysis estimated a significant seasonal pattern. For the total sample and for males suicide peaked in November (late spring) with a trough in May–June (late autumn). For females, the estimated peak occurred in January, and the trough in June–July. Conclusions: A seasonal pattern of suicides was found for both males and females, peaking in spring/summer and dipping in fall/winter. The scarcity of reports from intertropical latitudes warrants promoting more studies in this area.

AbstractObjectiveTo estimate the prevalence of underweight between 1998 and 2006 in Liverpool schoolchildren aged 9–10 years using recently published underweight cut-off points.Design and settingStature and body mass data collected at the LiverpoolSportsLinx project’s fitness testing sessions were used to calculate BMI.SubjectsData were available on 26 782 (n13 637 boys, 13 145 girls) participants.ResultsOverall underweight declined in boys from 10·3 % in 1998–1999 to 6·9 % in 2005–2006, and all sub-classifications of underweight declined, in particular grade 3 underweight, with the most recent prevalence being 0·1 %. In girls, the prevalence of underweight declined from 10·8 % in 1998–1999 to 7·5 % in 2005–2006. The prevalence of all grades of underweight was higher in girls than in boys. Underweight showed a fluctuating pattern across all grades over time for boys and girls, and overall prevalence in 2005–2006 represents over 200 children across the city.ConclusionsUnderweight may have reduced slightly from baseline, but remains a substantial problem in Liverpool, with the prevalence of overall underweight being relatively similar to the prevalence of obesity. The present study highlights the requirement for policy makers and funders to consider both ends of the body mass spectrum when fixing priorities in child health.

Unsafe sanitation is an increasing public health concern for rapidly expanding cities in low-income countries. Understanding household demand for improved sanitation infrastructure is critical for planning effective sanitation investments. In this study, we compared the stated and revealed willingness to pay (WTP) for high-quality, pour-flush latrines among households in low-income areas in the city of Nakuru, Kenya. We found that stated WTP for high-quality, pour-flush latrines was much lower than market prices: less than 5% of households were willing to pay the full costs, which we estimated between 87,100–82,900 Kenyan Shillings (KES), or 871–829 USD. In addition, we found large discrepancies between stated and revealed WTP. For example, 90% of households stated that they would be willing to pay a discounted amount of 10,000 KES (100 USD) for a high-quality, pour-flush latrine, but only 10% of households redeemed vouchers at this price point (paid via six installment payments). Households reported that financial constraints (i.e., lack of cash, other spending priorities) were the main barriers to voucher redemption, even at highly discounted prices. Our results emphasize the importance of financial interventions that address the sizable gaps between the costs of sanitation products and customer demand among low-income populations.

Engaging with regional, international, and spatial histories, this article proposes a new reading of the twentieth-century Polish past by exploring the vicissitudes of a building known as the Upper Silesia Tower. Renowned German architect Hans Poelzig designed the Tower for the 1911 Ostdeutsche Ausstellung in Posen, an ethnically Polish city under Prussian rule. After Poland regained its independence following World War I, the pavilion, standing centrally on the grounds of Poznań’s International Trade Fair, became the fair's symbol, and over time, also evolved into visual shorthand for the city itself. I argue that the Tower's significance extends beyond Posen/Poznań, however. As an embodiment of the conflicts and contradictions of Polish-German historical entanglements, the building, in its changing forms, also concretized various efforts to redefine the dominant Polish national identity away from Romantic ideals toward values such as order, industriousness, and hard work. I also suggest that eventually, as a material structure harnessed into the service of socialism, the Tower, with its complicated past, also brings into relief questions about the regional dimensions of the clashes over the meaning of modernity during the Cold War.

This paper explores the documentation of social and spatial transformation in the Walworth area, South London. Spatial narratives are the entry point for my exploration, where official and ‘unofficial’ representations of history are aligned to capture the nature of urban change. Looking at the city from street level provides a worldly view of social encounter and spaces that are expressive of how citizens experience and shape the city. A more distanced view of the city accessed from official data reveals different constructs. In overlaying near and far views and data and experience, correlations and contestations emerge. As a method of research, the narrative is the potential palimpsest, incorporating fragments of the immediate and historic without representing a comprehensive whole. In this paper Walworth is documented as a local and Inner City context where remnants and insertions are juxtaposed, where white working class culture and diverse ethnicities experience difference and change. A primary aim is to consider the diverse experiences of groups and individuals over time, through their relationship with their street, neighbourhood and city. In relating the Walworth area to London I use three spatial narratives to articulate the contemporary and historic relationship of people to place: the other side examines the physical discrimination between north and south London, the other half looks at distinctions of class and race and other histories explores the histories displaced from official accounts.

AbstractHuman physiological arousal is highly sensitive to information and uncertainty. Little is known, however, about how to measure information in natural settings, nor about which physiological systems respond to it. Financial market prices, and their volatility, present a convenient measure of informational load. Here we report on a study into the physiological response of traders in the City of London during a period of extreme, but declining, volatility. We sampled salivary cortisol, the main stress hormone, and the pro-inflammatory cytokines, IL-1β, IL-6, IL-8, and TNF-α three times a day for two weeks. We found that average daily cortisol levels tracked closely an index of equity and bond volatility, as did levels of IL-1β. Within-day cortisol and IL-1β levels also tracked one hour lagged volatility. Interestingly, the cascade of endocrine and immunological changes was initiated by IL-1β, the first responder of the stress and inflammatory responses. Our results have implications for finance because chronic stress and the immune response known as ‘sickness behaviour’ could have powerful effects on risk-taking and market stability.

The Mexican Caribbean and its main cities have the highest population growth rate in Mexico. This work goal was to analyze the growth of the city of Chetumal and the geopedological characteristics in which it has been developed, to identify potential hazards and thereby improve development programs. The methodology consisted in the study of geopedological characteristics and the analysis of land use changes in the city over time. The main problems of Chetumal are floods and subsidence. Floods are more common in areas where Gleysols soils are found in low-lying areas. The subsidence is associated to Leptosols with a phreatic mantle at a shallow depth where the precipitations favors dissolution of rock. The extrapolation of the relationships between geopedological conditions and the area occupied by the city, allows us to suppose that areas which the current Urban Development Program proposes for future city expansion will develop the same problems of subsidence and flooding as the areas already built in sites with similar conditions.
