Research on Unrealistic Optimism among HoReCa Workers as a Possible Future Hotspot of Infections
2021
As we are facing a new surge of the highly infectious delta variant of COVID-19, there is an urgent need for research to reduce the harm before this next wave hits. In the present paper, we present data that is alarming. We have found that HoReCa (hotels, restaurants, and catering services) workers, who are highly exposed to many new social interactions in close contact, present an unrealistic optimism (UO) bias: they perceive themselves as less at risk to this virus in comparison to others. From the literature, we already know that individuals holding this view are less involved in preventive actions and present more risky behaviors. In the face of the delta variant, this leads to the conc…
National level paths to the mining industry’s Social Licence to Operate (SLO) in Northern Europe: The case of Finland
2020
Abstract Research on the social licence to operate (SLO) has traditionally focused on local communities directly affected by mining operations. There has been a lack of systematic research exploring attitudes to mining among the public at large. Based on a national survey (N = 1091) of Finns’ attitudes towards mining conducted in 2016, we test a theoretical model using path analysis to examine the factors affecting the social licence to operate (SLO) of mining in Finland. The aim is to shed light on the factors affecting SLO at national level in Finland and to add to the growing body of research seeking to understand the mining industry’s SLO at national level in diverse social, economic an…
High performance hardware correlation coefficient assessment using programmable logic for ECG signals
2003
Abstract Correlation coefficient is frequently used to obtain cardiac rhythm by peak estimation and appreciate differences in the signal compared to a pattern. This work focuses on the description of a real-time correlation assessment procedure. Applied to electrocardiogram (ECG) signals, a new correlation value is obtained every new sample and pulse detection information is provided. The ECG pattern is internally stored and can be changed when desired. This procedure is useful in Systems on Chip implementation and can be applied to design compact ECG monitoring systems consisting on a system on chip where programmable logic offloads the main processor. A Xilinx FPGA device has been used fo…
Illegal fishing in Isla del Coco National Park: Spatial-temporal distribution and the economic trade-offs
2020
Abstract The Isla del Coco National Park, located on the Pacific coast of Costa Rica, is rich in biodiversity and has a high concentration of pelagic species. This high marine biodiversity makes the Isla del Coco National Park (PNIC) a very attractive place for illegal fishers. We analyzed a dataset covering 8 years (2003–2010) of patrol records from PNIC with the aim of determining, a) the spatial-temporal distribution of illegal fishing, b) other areas that could be prone to illegal fishing but are currently undetected, c) the most profitable areas for this activity and d) the economic trade-offs of this illegal activity in relation to potential gains and the costs. Residuals Autocovariat…
A fast BEM for the analysis of damaged structures with bonded piezoelectric sensors
2010
A fast boundary element method for the analysis of three-dimensional solids with cracks and adhesively bonded piezoelectric patches, used as strain sensors, is presented. The piezoelectric sensors, as well as the adhesive layer, are modeled using a 3D state-space finite element approach. The piezoelectric patch model is formulated taking into account the full electro-mechanical coupling and embodying the suitable boundary conditions and it is eventually expressed in terms of the interface variables, to allow a straightforward coupling with the underlying host structure, which is modeled through a 3D dual boundary element method, for accurate analysis of cracks. The technique is computationa…
(Un)sustainable creativity? Different manager-employee perspectives in the finnish technology sector
2020
The importance of creativity for working life and in organizations has increased in recent years. At the same time, the theme of sustainability has been intensely debated in research, society, and organizations. Together, creativity and sustainability have sometimes been described as a contradictory phenomenon: they are described in ways that place them in opposition to each other. To better understand creativity and sustainability and their differences from the perspective of people in different positions, we take advantage of a sociocultural approach in which we do not focus only on creative individuals but also on the impact of creativity on both organizational stakeholders and society a…
Facing globalization and increased trade: Catalonia's evolution from industrial region to knowledge and creative economy
2011
Catalonia is experiencing a crucial transformation of its productive model. The main changes are exemplified by an intense process of substitution of the traditional aspects (low-technology manufacturing base and orientation towards internal markets) for a model of development characterized by the combined importance of creative industries and high-tech manufacturing activities, and oriented to external markets. The new competitive bases of the regional economy rely on three factors: urbanization and network economies, changes in the productive structure and the generation of innovations linked with export capacity. Resumen. Cataluna esta experimentando una transformacion crucial de su mode…
Removal of Escherichia coli from Saturated Sand Columns Supplemented with Hydrochar Produced from Maize
2014
Despite numerous studies on hydrochar use, its application in water treatment for pathogen removal remains unexplored. In this study, we evaluated the efficiency of hydrochar produced from crop residue of maize for water treatment by determining Escherchia coli breakthrough from sand columns supplemented with hydrochar. To enhance the adsorptive capacity, raw hydrochar was activated by 1 mol L⁻¹ KOH at room temperature. The experiments conducted in a 10-cm sand bed with 1.5% (w/w) activated and raw hydrochar supplements, not activated by KOH, showed 93 and 72% of E. coli removal efficiencies, respectively. Activation of KOH not only enhanced the E. coli removal but also increased the streng…
Use of NOAA-AVHRR NDVI data for environmental monitoring and crop forecasting in the Sahel. Preliminary results
1992
Abstract Several studies have shown that the NDVI calculated from NOAA-AVHRR data is related to annual rainfall and primary productivity in Sahelian areas. Such correlations, however, are affected by several environmental factors and have been tested only with data accumulated during rainy seasons, which is not ideal for the prediction of crop yield. In the present study a methodology of NOAA AVHRR data processing is presented which utilizes NDVI computed only in the first part of some rainy seasons and statistically takes into account the geographical variability in land resources and atmospheric conditions. From the first results of the application of the methodology in Niger, its potenti…
From the LCA of food products to the environmental assessment of protected crops districts: A case-study in the south of Italy
2010
In the present study, Life Cycle Assessment (LCA) methodology was applied to evaluate the energy consumption and environmental burdens associated with the production of protected crops in an agricultural district in the Mediterranean region. In this study, LCA was used as a ‘support tool’, to address local policies for sustainable production and consumption patterns, and to create a ‘knowledge base’ for environmental assessment of an extended agricultural production area. The proposed approach combines organisation-specific tools, such as Environmental Management Systems and Environmental Product Declarations, with the environmental management of the district. Questionnaires were distribute…
