O presente estudo trata da temática da relação sociedade natureza, considerando as repercussões da apropriação do espaço no estuário da Baía do Pontal-Ilhéus/BA. O recorte temporal adotado foi da década de 70 do século XX até o ano de 2012. A abordagem da pesquisa foi qualitativa, adotando, quando necessário, técnicas quantitativas. Os instrumentos de coleta constituíram-se de observação sistemática e entrevistas, além de pesquisa documental e bibliográfica. As análises efetuadas permitiram constatar que as intervenções socioespaciais na Baía do Pontal originam-se da construção do Porto de Ilhéus na porção norte, da degradação ambiental crescente das bacias dos rios tributários (rios Cachoeira, Santana e Itacanoeira) e do processo de ocupação do entorno da Baía. Essas pressões causaram alterações na dinâmica de circulação do estuário, levando-o a um estado de progradação de praia, intensificação no processo de assoreamento da baía, propensão à formação de mangues e comprometimento da qualidade da água, devido ao lançamento de esgotos. Abstract ENVIRONMENTAL IMPACTS IN THE PROCESS OF SOCIAL OWNERSHIP OF SPACE IN THE BAY OF THE PONTAL IN MUNICIPALITY OF ILHÉUS / BA This study is about the relationship between society and nature, considering the impact of the appropriation of space in the estuary of Pontal Bay -Ilhéus/BA. The time frame adopted begins with the 70s and extends until the year 2012. The research approach was qualitative, adopting quantitative techniques when necessary. The instruments of collection consisted of systematic observation and interview, plus documentary and bibliographic research. The analyzes showed evidence that the socio-spatial interventions in the Bay originate from the construction of the Port of Ilheus in the northern portion, from the growing, environmental degradation of river basins tributaries (rivers Cachoeira, Santana and Itacanoeira) and from the process of occupation surrounding the Bay. These pressures have caused changes in the dynamics of estuarine circulation, leading to a state of beach progradation, intensifying the process of silting up of the Bay, propension to formation of mangroves and impaired water quality due to discharge of sewage.

Since 2013, there has been an increase (>23%) in naval traffic using maritime routes and ports on the coastal fringe of Santa Marta, Colombia. Of major concern, and described by several studies, is the relationship between maritime traffic and coastal contamination. This study proposed a maritime traffic indicator considering the simultaneous effects of several relevant measurements of water quality parameters to estimate the impact of naval activity. The approach involved developing a model including the number of vessels, hull length, and permanence time in berths. In addition, water quality variables, considering climatic seasons, were used to verify association with maritime traffic and touristic activities. The high concentrations of total coliforms (TC) and dissolved/dispersed petroleum hydrocarbons in chrysene equivalents (DDPH) reported by the International Marina of Santa Marta (SM) were affected by the local anthropic activities, including tourism, naval traffic, and urban wastewater discharges. Moreover, our results suggest the occurrence of multiple chemical impacts within Tayrona National Natural Park (PNNT) affecting conservation goals. The estimation of the maritime traffic indicator proposed in this study may be an easy and more complete tool for future studies evaluating the impact of naval activities on environmental quality.

Development Practice

Information systems development takes place within an economical context. However, the economical conditions, which shape systems development in practice, are hardly researched. In this paper we are investigating the question how a given price structure influences systems development projects. Our analysis is based on a multi case study and a Grounded Theory inspired research approach. Our work is informed by economic theories, which deal with the relationship of suppliers and customers and their mutual dependency. We thus apply principal-agent theory and economic game theory in form of the prisoner’s dilemma. As a result we provide three interlinked models for understanding the impact of pricing structure on systems development practice. The main elements of these models are pricing structure, risk distribution and price level, and opportunistic behavior. We discuss how these elements are interrelated and examine their impact on information systems development in practice.

The aim of this study was to determine the feasibility of combining water quality analysis with different biomarkers to characterise the relationship between anthropogenic contamination and biotic response in the Sinos River, southern Brazil. Wistar rats were studied using three biomarkers combined with physical, chemical and microbiological analysis to assess the effects of pollution at four sampling sites. The induction of oxidative stress was quantified by MDA levels in peripheral blood, lymphocyte DNA damage was determined using the comet assay, and histopathological changes were analysed in the liver. After sampling, animals were allowed to drink the river water during a 48 hours period. No increase in oxidative stress and DNA damage was observed. However, liver damage was observed in the animals exposed to water samples, indicating that the Sinos River is contaminated with hepatotoxic substances. Water analyses confirmed that water quality decreased downriver.

This chapter discusses the relationship between the environment and security. The concept of ‘environmental security’ is omnipresent, but is nonetheless ambiguous and contested. What exactly needs to be secured, and what are the security threats? Is environmental security about state security, faced with the loss of natural resources? Or is it about protecting individuals and communities from environmental degradation and reduced access to key environmental resources? A first step in clarifying these questions is to disentangle two related but distinct causal arguments. In the relationship between environment and security, environmental degradation can be analysed either as a cause or as a consequence of security issues. A second step needed to clarify these debates is to adopt clear definitions. In the context of international relations, security has traditionally been understood in relation to the survival of the state, and the main threats to state security are armed conflicts. For the purpose of this chapter, conflicts are defined as any type of disagreement. The chapter also examines the impact of conflicts on the environment.

The role of investment banks in M&A operations is analyzed on the basis of empiric evidence. In particular, to point out the variations in the impact of the certification effect which can be ascribed to investment banks, the relationship between the value created for the shareholders in companies involved in special underwriting operations and the reputation of the banks appointed to act as advisors is examined. The analysis, which uses an original measuring system in order to assess and classify the reputation variable, focuses on transactions that have taken place between listed companies in two time frames, symmetrical to each other, specifically pre and post the Lehman Brothers bankruptcy. The total sample is composed of 229 transactions, divided into 161 and 68 observations, respectively pre and post Lehman. The result is that in the post Lehman period, unlike the preceding time frame, for which no significant empiric evidence is found, the wealth of the shareholders (of both targets and acquirers) is significantly influenced by the reputation of the investment banks which have acted as advisors. This indicates that, subsequent to the shock of the Lehman Brothers collapse, the certifying effect of the investment banks takes on an important role in the shareholders' choice.

Abstract. Direct and indirect effects from human activity have dramatically increased nutrient loading to aquatic inland and estuarine ecosystems. Despite an abundance of studies investigating the impact of agricultural activity on water quality, our understanding of what determines the capacity of a watershed to remove or retain nutrients remains limited. The goal of this study was to identify proximate and ultimate controls on dissolved organic carbon and nutrient dynamics in small agricultural catchments by investigating the relationship between catchment characteristics, stream discharge, and water chemistry. We analyzed a 5-year, high-frequency water chemistry data set from three catchments in western France ranging from 2.3 to 10.8 km2. The relationship between hydrology and solute concentrations differed between the three catchments and was associated with hedgerow density, agricultural activity, and geology. The catchment with thicker soil and higher surface roughness had relatively invariant carbon and nutrient chemistry across hydrologic conditions, indicating high resilience to human disturbance. Conversely, the catchments with smoother, thinner soils responded to both intra- and interannual hydrologic variation with high concentrations of phosphate (PO43−) and ammonium (NH4+) in streams during low flow conditions and strong increases in dissolved organic carbon (DOC), sediment, and particulate organic matter during high flows. Despite contrasting agricultural activity between catchments, the physical context (geology, topography, and land-use configuration) appeared to be the most important determinant of catchment solute dynamics based on principle components analysis. The influence of geology and accompanying topographic and geomorphological factors on water quality was both direct and indirect because the distribution of agricultural activity in these catchments is largely a consequence of the geologic and topographic context. This link between inherent catchment buffering capacity and the probability of human disturbance provides a useful perspective for evaluating vulnerability of aquatic ecosystems and for managing systems to maintain agricultural production while minimizing leakage of nutrients.

This paper investigates the impact of the Learning Resource Centre activities of Westminster International University Tashkent (WIUT) graduated students on the labour market outcome. WIUT library provides a learning environment that helps students to create practical teams and individual projects to support the agenda of employability. The study aims to clarify the relationship between library activities and labour market outcomes. This proposes the improvement of a commercial responsiveness workshop, in collaboration with other services, and alumni voices in an employability guide. A quantitative research approach was employed; an online survey questionnaire was distributed to alumni students to obtain the data. It was a semi-structured questionnaire designed using a Likert Scale to collect data from 607 graduates. The study revealed that LRC activities have a significant impact on labour market outcomes for students. LRC activities such as presentation skills, information technology skills, problem-solving skills, research skills were mostly expected in the labour market. Research limitations– The study was focused only on graduates of WIUT, which may limit the generalizability. Therefore, the researcher proposed to study and compare other graduates of universities in Uzbekistan. The insights are valuable for planning the curriculum of LRC activities and developing teaching practices at WIUT. Moreover, current and graduate students can learn market-oriented skills and labour market demands. This is the first-ever study in Uzbekistan that explores the relationship of university library activities on employability skills of alumni.

<p>Despite the fact of being the largest economy in Latin America, piped water service coverage and sewage collection is not universal in Brazil. The relationship between access to water/sanitation and health was the objective of many studies recently. The majority of the existing work focuses on the impact of access to water and sewage, not investigating the effects of water quality and treatment. Moreover, the existing literature usually focuses on infant mortality and life expectancy indicators. Although these measures are important, they may not capture all the relevant public costs associated with health and related to hospitalizations. This paper aims at filling this gap by identifying the effects of sanitation policies on children morbidity rates by certain diseases in Brazilian municipalities.</p>

As an effort to identify the underlying determinants of willingness to pay, this study seeks to examine brand image, customer trust, and customer loyalty that impacts directly on willingness to pay during the 2020 COVID-19 pandemic time frame. This study also seeks to identify the impact of customer trust and brand image towards willingness to pay though customer loyalty and to identify the indirect impact of customer trust and brand image towards willingness to pay during the 2020 COVID-19 pandemic time frame. Using a convenient sampling method, someone who ever bought some sports apparel during this COVID-19 pandemic were selected as the sample. Out of 230 distributed, 171 useful questionnaires were returned. Confirmatory factor analysis and path analysis were conducted using partial least square equation modelling. The results of this study showed that the willingness to pay of sports apparel during the pandemic covid 19 in Indonesia was influenced by the customer trust and customer loyalty but not significantly influenced by the brand image. This study has a different research originality by researching the relationship between brand image, customer trust, customer loyalty and willingness to pay of any sports apparel during a specific time frame of the 2020 COVID-19 Pandemic, also the impact of brand image and customer trust towards willingness to pay were a rare relation of a research.
