In this article, the author identifies the concentration principle for the accumulation of large quantities of objects in the settlements of the Balkan Neolithic and Copper Age and suggests reasons for this principle. One of the chief examples of this principle is the structured deposition of objects in pits. After the characterisation of the location of such pits – whether under houses or in the open air, there is a discussion of the forms of deposits in pits – including human bone deposits, burnt deposits and unusual combinations of rare and quotidian objects, as related to different manifestations of the life-cycle of the pits. The structure of the deposits is investigated in the light of their immense variability. Rather than attempting to ‘explain’ all the cited examples in a global, structuralist manner, the pits and their contents are interpreted in terms of local strategies of categorisation of everyday and exotic materials used in social practices. This does not exclude broader forms of prehistoric rationality, which appear to endure over a long period of time and in many different regions. These findings are related to the wider social dynamics of enchainment and accumulation – two important long-term social practices characterising the Balkan Neolithic and Copper Age.

This study is based upon personal interviews with 47 elderly bereaved parents. These interviews provided us with detailed and extensive information on the bereavement processes that parents experience over a long period of years. From an in-depth content analysis of the interviews and the way the parents described bereavement, it seems that it is a central motif in their lives affecting their relationships with each other, with the living children, with friends, at work and with others. Although enduring grief along the life cycle is an un-patterned process with emotional and cognitive ups and downs, involving a continuous search for a meaning to life, we observed a development in this process throughout the years. As we proposed in a previous study (Malkinson & Bar-Tur, 2000) there are three main identifiable phases in the bereavement process: the immediate, acute phase; grief through the years until aging; and bereavement in old age. We propose to refer to them as the three main phases in the development of parental grieving process and name them “young grief,” “mature grief,” and “aging grief.”

Long-term studies of the life cycle of Chaetopteryx villosa (Fabricius) have been conducted in Wolbórka Spring, in the vicinity of Łódź (Central Poland). The emergence period of adults lasts from the beginning of October until mid December. During this relatively long period, adults are exposed to diverse weather conditions. Low (sometimes below zero) ambient temperatures influence the survival of adults. Although oviposition usually starts at the end of October, freshly laid eggs were found even in January. These temperatures also determine the activity of predators as well as the development and survival of eggs laid on land. Some egg masses have been transferred to the laboratory and bred at different temperatures.

AbstractWhat is the basis for the enormous success of Historicism? In my paper I attempt to answer this question by deploying the concept of the cultural pattern. A ‘cultural pattern’ may be defined as the connection of concepts and practices which have gained a relative perpetuity through cultural habitualization. Cultural patterns include a combination of interpretative schemes according to which the world can be categorized, structured and interpreted with individual or social practices which either develop out of, or follow these schemes. Because they combine concepts and practices in a significant manner they gain a contour which enables the creation of communicative addressability, practical appropriation and discursive analysis and hence the creation of a long-term exemplary status. A cultural pattern according to this definition has a relative stability and an observable effect over a long period of time, but which is simultaneously liable to permanent actualization and adaption. Historicism has been considered to be a basic thought-pattern of modernity since Troeltsch, Meinecke and Koselleck; defining Historicism as a cultural pattern can help to explain its long-term effectiveness and its continuing productivity to the present day.

Abstract Various information technology (IT) infrastructures for biobanking, networks of biobanks and biomaterial management are described in the literature. As pre-analytical variables play a major role in the downstream interpretation of clinical as well as research results, their documentation is essential. A description for mainly automated documentation of the complete life-cycle of each biospecimen is lacking so far. Here, the example taken is from the University Medical Center Göttingen (UMG), where the workflow of liquid biomaterials is standardized between the central laboratory and the central biobank. The workflow of liquid biomaterials from sample withdrawal to long-term storage in a biobank was analyzed. Essential data such as time and temperature for processing and freezing can be automatically collected. The proposed solution involves only one major interface between the main IT systems of the laboratory and the biobank. It is key to talk to all the involved stakeholders to ensure a functional and accepted solution. Although IT components differ widely between clinics, the proposed way of documenting the complete life-cycle of each biospecimen can be transferred to other university medical centers. The complete documentation of the life-cycle of each biospecimen ensures a good interpretability of downstream routine as well as research results.

The urbanization process contributes to the growth of solid waste generation and causes an increase in environmental impacts and failures in the management of solid waste. The number of dumps is a concern due to the limited implementation and safe disposal of this waste. The interest in sustainable techniques has been growing in relation to waste management, which is largely absorbed by the civil construction sector. This work aimed to review plastic waste, especially polyethylene terephthalate (PET), that can be incorporated with construction materials, such as concrete, mortars, asphalt mixtures, and paving. The use of life-cycle assessment (LCA) is related, as a tool that allows the sustainability of products and processes to be enhanced in the long term. After analyzing the recent literature, it was identified that studies related to plastic wastes in construction materials concentrate sustainability around the alternative destination of waste. Since the plastic waste from different production chains are obtained, it was possible to affirm the need for a broader assessment, such as the LCA, providing greater quantification of data making the alternative processes and products more sustainable. The study contributes to enhance sustainability in alternative building materials through LCA.

The objective of this paper was to explore long-term costs for a single-family house in Sweden during its entire lifetime. In order to estimate the total costs, considering construction, replacement, operation, and end-of-life costs over the long term, the life cycle cost (LCC) method was applied. Different cost solutions were analysed including various economic parameters in a sensitivity analysis. Economic parameters used in the analysis include various nominal discount rates (7%, 5%, and 3%), an inflation rate of 2%, and energy escalation rates (2–6%). The study includes two lifespans (100 and 50 years). The discounting scheme was used in the calculations. Additionally, carbon-dioxide equivalent (CO2e) emissions were considered and systematically analysed with costs. Findings show that when the discount rate is decreased from 7% to 3%, the total costs are increased significantly, by 44% for a 100-year lifespan, while for a 50 years lifespan the total costs show a minor increase by 18%. The construction costs represent a major part of total LCC, with labor costs making up half of them. Considering costs and emissions together, a full correlation was not found, while a partial relationship was investigated. Results can be useful for decision-makers in the building sector.

Abstract Using administrative data for the population of Danish men and women, we develop an empirical model which accounts for the joint earnings dynamics of siblings and youth community peers. We provide the first decomposition of the sibling correlation of permanent earnings into family and community effects allowing for life cycle dynamics and extending the analysis to consider other outcomes. We find that family is the most important factor influencing sibling correlations of earnings, education and unemployment. Community background matters for shaping the sibling correlation of earnings and unemployment early in the working life, but its importance quickly diminishes.

The objective of this paper is to apply the life cycle assessment methodology to assess the environmental impacts of light steel framed buildings fabricated from cold formed steel (CFS) sections. The assessment covers all phases over the life span of the building from material production, construction, use, and the end of building life, in addition to loads and benefits from reuse/recycling after building disposal. The life cycle inventory and environmental impact indicators are estimated using the Athena Impact Estimator for Buildings. The input data related to the building materials used are extracted from a building information model of the building while the operating energy in the use phase is calculated using an energy simulation software. The Athena Impact Estimator calculates the following mid-point environmental measures: global warming potential (GWP), acidification potential, human health potential, ozone depletion potential, smog potential, eutrophication potential, primary and non-renewable energy (PE) consumption, and fossil fuel consumption. The LCA assessment was applied to a case study of a university building. Results of the case study related to GWP and PE were as follows. The building foundations were responsible for 29% of the embodied GWP and 20% of the embodied PE, while the CFS skeleton was responsible for 30% of the embodied GWP and 49% of the embodied PE. The production stage was responsible for 90% of the embodied GWP and embodied PE. When benefits associated with recycling/reuse were included in the analysis according to Module D of EN 15978, the embodied GWP was reduced by 15.4% while the embodied PE was reduced by 6.22%. Compared with conventional construction systems, the CFS framing systems had much lower embodied GWP and PE.
