Constructive Dynamic Program Slicing Research
2010
Program slicing is a promising technique for providing automated support for various important software engineering activities. There exists hundreds of scientific studies on the theory of slicing. However, slicing is still not widely applied in software industry. Therefore, there is a need to survey and characterize the conducted research and to analyze what problems hinder progress. This paper answers to that need by providing a survey of constructive dynamic program slicing research focusing on publication series with high visibility. The survey identified 12 dynamic slicers related to which 12 aspects were studied. The analysis revealed many issues which can be seen both as concerns and…
Screening of currently used pesticides in water, sediments and biota of the Guadalquivir River Basin (Spain)
2013
The occurrence of 50 currently used pesticides and their transformation products in surface and waste waters, sediment and fish in the Guadalquivir River Basin was determined in 2010 and 2011. After selective sample extraction, pesticides were identified and quantified by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The contamination profile in water and sediments is marked by the presence of organophosphorus and triazines. Transformation products were even at higher concentrations than parent pesticides. A wider range of pesticides was present in water than in sediments but none of them were detected in fish. The mean concentrations ranged from 0.2 to 13.0 ng/L in …
Network for blood pressure research in children and adolescents (COST Action CA 19115)
2021
High blood pressure is a clearly established modifiable risk factor for cardiovascular and renal disease. Although most of its adverse effects develop in adulthood, it has become clear that high BP is a lifelong problem that can manifest early in life. While few would dispute the importance of taking effective steps to identify and manage this condition in middle-aged and elderly individuals, relatively little attention has been paid to the problem of high BP in children and adolescents.Therefore, the development of actions focused on early childhood, childhood and adolescence and the investigation of the underlying causes of this epidemic are of utmost importance. There is a pressing need …
Experiences of Female Breast Cancer Survivors Concerning Their Return to Work in Spain
2021
The objective of this study was to analyze the experiences of returning to work of women who had overcome breast cancer, identifying its physical and psychological consequences, the process they underwent, their motivations, and difficulties. A total of 19 female breast cancer survivors, with an age range of 30 to 57 years, participated in two focus groups. A semi-structured script was prepared about their experiences of returning to work. The results indicated that survivors’ self-perception was weakened by the physical and psychological consequences of the treatment of the disease
Modifications in Water Resources Availability Under Climate Changes: A Case Study in a Sicilian Basin
2014
Climate variability due to the greenhouse effect has important implications on hydrological processes and water resources systems. Indeed, water availability, quality and streamflow are very sensitive to changes in temperature and precipitation regimes whose effects have to be fully considered in current water management and planning. International literature proposes several models, attempting to assess accurately the available water resources under stationary and changing climatic conditions at different spatial and temporal scales. In order to assess the potential impacts of climate change on surface and groundwater resources water availability in a Southern area of Italy, a conceptual h…
Bridging Mediterranean cultures in the International Year of Soils 2015: A documentary exhibition on irrigation techniques in water scarcity conditio…
2017
The paper presents the activity performed at the University of Brescia by students and researchers, belonging to different Mediterranean cultures and different disciplines, to prepare a documentary exhibition on irrigation techniques in water scarcity conditions, on the occasion of the International Year of Soils 2015. Traditional irrigation techniques were identified as a key aspect of soil conservation and agricultural practices, to build living and autopoietic ecosystems, also in adverse climatic conditions, and to adapt to climatic changes. Being a structural source of ecosystem survival, and being based on long-lasting observation of the climate and of the environment, they have deep r…
Monitoring Soil Salinisation as a Strategy for Preventing Land Degradation: A Case Study in Sicily, Italy
2010
Water demand is increasing worldwide. In regions affected by water scarcity such as those located in the Mediterranean basin, water supplies are already degraded, or subjected to degradation processes, which worsen the water shortage. In Sicily, the increasing scarcity of good quality water is expanding irrigation with saline-sodic waters, thus enhancing the risk of secondary salinization and sodification. Adequate management practices are urgently needed for sustainable use of saline/sodic waters. This chapter illustrates how the Geonics EM-38 probe was used for monitoring salinization in a Sicilian area where irrigation with saline water is increasingly practiced, and the risk of salinisa…
Survey data and Bayesian analysis: a cost-efficient way to estimate customer equity
2014
We present a Bayesian framework for estimating the customer lifetime value (CLV) and the customer equity (CE) based on the purchasing behavior deducible from the market surveys on customer purchasing behavior. The proposed framework systematically addresses the challenges faced when the future value of customers is estimated based on survey data. The scarcity of the survey data and the sampling variance are countered by utilizing the prior information and quantifying the uncertainty of the CE and CLV estimates by posterior distributions. Furthermore, information on the purchase behavior of the customers of competitors available in the survey data is integrated to the framework. The introduc…
The requisite match between internal resources and network ties to cope with knowledge scarcity
2020
PurposeThis paper aims to investigate the internationalization strategies of small and medium enterprises (SMEs), focusing on the interaction between network ties and “soft” internal resources at the foundation of knowledge management (KM). Specifically, it identifies the firms’ internal capabilities that affect KM strategies, and their collective influence on the degree of internationalization; verifies the influence of network ties on the internationalization process itself; and develops a conceptual “preliminary theoretical framework of SME internationalization capabilities and networks.”Design/methodology/approachThe primary research and analysis are based on a proportional stratified s…
The Relationship Between Overeducation and Job Satisfaction Among Young Spanish Workers: The Role of Salary, Contract of Employment, and Work Experie…
2010
The increase of education in younger generations and the relative scarcity of qualified jobs available for them makes overeducation of young employees a social issue. We explored the relationships between overeducation and job satisfaction (extrinsic, intrinsic, social facet), as well as the direct and moderating role of salary, contract of employment, and work experience in these relationships using hierarchical regression analyses. Data were collected from a sample of 643 young Spanish employees. As expected, there were negative relationships between overeducation and all 3 satisfaction facets. Moreover, high work experience emerged as a moderating factor that buffered the negative effect…
