Recycling Techniques

Abstract Urbanization, development of economy, increasing population and improved living standards and lifestyle have caused a sharp growth in waste. Inappropriate or inefficient waste disposal techniques can cause serious air, soil, and groundwater pollution, which subsequently can negatively affect the urban environment and threaten the health of residents. The goal of waste management is to move to a circular economy in which waste does not exist. If there is no possible way to reduce or reuse waste, the best solution is recycling it. Recycling brings abundant benefits on the economic and ecological levels levels, and helps reduce overall human health risk of adverse impacts. Recycling of the waste-cables which contain PVC and copper replaces the production of virgin PVC and mining of copper from copper ore, it reduces landfill solid waste pressures, saves energy and water sources, reduces emissions to environment, and also reduces negative impacts from improperly dispose of waste, etc. This paper presents an overview of recycling techniques for the waste-cables containing copper as a core and polyvinyl chloride as an insulating layer or sheath. It also lists advantages and disadvantages of these techniques and importance of recycling this type of waste.

Unexpected Outcomes

Often risks arise because of more than one choice and the impact of each option is not yet known for certain, as uncertain future. There is always an opportunity cost that follows every option taken. Thus, risks may be defined as the consequences of uncertain options that have the potential to lead to unexpected outcomes or other adverse impacts to decision makers. This is the classic definition of risk. From this definition, risk contains several dimensions, namely opportunity costs, potential losses or other negative impacts, uncertainty, and obtaining results that do not match expectations. It is with these demands that risks are measured, mitigated and monitored during the business process.

Purpose The purpose of this paper is to compare morphological and physical features of three kinds of materials intended for the insulating layer in the clothing protecting against cold – high-bulk non-woven, goose down (GD) and duck down (DD). Design/methodology/approach Comparison of thermal performance of developed textile systems with the non-woven, GD and DD content was based on basic biophysical properties related to comfort sensations of the user such as thermal resistance, water vapor resistance and air permeability. In this study, light microscopy and scanning electron microscopy methods were employed to visualize the surface and internal structure of non-woven, GD and DD samples. Findings The paper indicates the advantages and disadvantages of each of selected insulating material. For the down samples, significantly higher thermal resistance in a dry state than for the non-woven samples can be achieved. Meanwhile, textile systems with the non-woven provide lower value of water vapor resistance. The selected textile systems for the research were characterized by a comparable air permeability. Originality/value This paper allows for an evaluation of high-bulk non-woven, DD and GD samples in terms of providing optimal thermal performance in clothing protecting against cold.

Abstract SRPP 2020 Ollie Randall Symposium Award Winner. Many of the detrimental effects of material disadvantage on the lives of citizens have been well understood by public health and social scientists, and post-World War II social protection polices were designed to mitigate the negative impacts of them. As the numbers of older people increase proportionally to the rest of the population in most countries, less is known about the exclusionary impacts of material disadvantage and the roles housing, poverty and living standards play on the health, well-being and social connections of their lives. This symposium draws together research emanating out of four countries Norway, Poland, Ireland and New Zealand that are part of the European COST Action 15122 Reducing Old-Age Social Exclusion: Collaborations in Research and Policy (ROSEnet). The papers present contemporary results of specific health well-being and social impacts of material disadvantage in the four quite different countries and assesses them through the lens of social exclusion. As the growing international evidence during the last decade has highlighted the negative health and well-being impacts of loneliness and social disconnection (Holt-Lunstad et. al. 2015), the role of housing, poverty and living standards has in creating social exclusion is less well known. This research analyses the subjective and objective experiences of material disadvantage and quantifies their exclusionary impacts on well-being (e.g. quality of life, loneliness), health functioning (mental and physical) and their challenges to macro-structures (e.g. government policies, social protection).

Abstract The impacts of the COVID-19 pandemic extend to global biodiversity and its conservation. Although short-term beneficial or adverse impacts on biodiversity have been widely discussed, there is less attention to the likely political and economic responses to the crisis and their implications for conservation. Here we describe four possible alternative future policy responses: (1) restoration of the previous economy, (2) removal of obstacles to economic growth, (3) green recovery and (4) transformative economic reconstruction. Each alternative offers opportunities and risks for conservation. They differ in the agents they emphasize to mobilize change (e.g. markets or states) and in the extent to which they prioritize or downplay the protection of nature. We analyse the advantages and disadvantages of these four options from a conservation perspective. We argue that the choice of post-COVID-19 recovery strategy has huge significance for the future of biodiversity, and that conservationists of all persuasions must not shrink from engagement in the debates to come.

The article is devoted to the analysis of features of enterprise profit management. The research of practical aspects of profit management of the energy sector enterprises is due to legislative changes and a significant impact on the economy of country and living standards. Scientific approaches to the concept of operational leverage are considered and its role in profit formation is substantiated. The peculiarities of using the operating lever to forecast the operating profit of the enterprise are revealed. The concept of CVP-analysis is used. The target function of maximizing operating profit is studied taking into account the pricing policy. Scenarios for increasing of the company’s profit reserves based on the strength of the operational leverage are calculated. The main ways of using of the company’s profit according to five selected scenarios are outlined and their advantages and disadvantages are analyzed. Break-even points and safety zones are calculated for each of the scenarios, which allow to take into consideration the possible risks of the enterprise and to make economically sound decisions to the management. The projected increase in net profit is calculated as a result of correlation analysis and based on comparative analysis; the choice of the best scenario to increase profitability is justified. Not only tactical but also strategic aspects of management which are aimed at maximizing the final result of the enterprise are taken into account. The analysis also considers the peculiarities of the introduction of incentive regulation and the need to correct the regulatory rate of return on regulatory asset bases. The proposed measures will increase both qualitative and quantitative parameters of the enterprise profit management system, which will contribute to economic stabilization for the enterprise and consumers. Prospects for further research based on the use of operational leverage are outlined. Keywords: profit, profit management, incentive regulation, operational leverage, profitability reserves.

Using data from the 2007 Timor-Leste Living Standards Survey, this paper examines the determinants of household energy choices in Timor-Leste. The majority of households are dependent on dirty fuels such as fuelwood and kerosene for energy. Only a small fraction of households use clean energy such as electricity. Econometric results show that wealthy households, urban households, and those headed by individuals with higher levels of education are less likely to use and depend on kerosene and more likely to use and depend on electricity. While female-headed households are generally more likely to use and depend on fuelwood, richer female-headed households are more likely to use and depend on electricity. Our findings highlight the importance of ensuring an adequate supply of clean energy for all at affordable prices and of investing in education to raise awareness about the adverse impacts of using dirty fuels.

Vibrio Spp

Densely populated, low-lying coastal areas are most at-risk for negative impacts from increasing intensity of storm-induced flooding. Due to the effects of global warming and subsequent climate change, coastal temperatures and the magnitude of storm-induced flooding are projected to increase, creating a hospitable environment for the aquatic Vibrio spp. bacteria. A relative risk model analysis was used to determine which census block groups in coastal South Carolina have the highest risk of Vibrio spp. exposure using storm surge flooding as a proxy. Coastal block groups with dense vulnerable sub-populations exposed to storm surge have the highest relative risk, while inland block groups away from riverine-mediated storm surge have the lowest relative risk. As Vibriosis infections may be extremely severe or even deadly, the best methods of infection control will be regular standardized coastal and estuarine water monitoring for Vibrio spp. to enable more informed and timely public health advisories and help prevent future exposure.
