Current status and development of sanitation and wastewater treatment in the national and international context
2012
El acceso al saneamiento y depuración de aguas residuales es un aspecto de suma importancia tanto desde el punto de vista ambiental como sanitario. Por ello, desde el Imperio Mesopotámico hasta la actualidad se han producido importantes avances en esta materia. Sin embargo, en la actualidad, en la mayoría de los países en vías de desarrollo el acceso al saneamiento continua siendo deficitario. Por otra parte, los países desarrollados, que sí disponen de sistemas adecuados de depuración de aguas residuales, se enfrentan al reto de mejorar la sostenibilidad de estos sistemas. En este trabajo se describe en profundidad el estado actual y evolución en el tiempo del saneamiento y depuración de a…
Schooling effects and earnings of French University graduates: school quality matters, but choice of discipline matters more
2010
Our aim in this article is to study the relation between earnings of French universities graduates and some characteristics of their universities. We exploit data from the Céreq's "Génération 98" survey, enriched with information on university characteristics primarily from the ANETES (yearbook of French institutions of higher education). We employ multilevel modeling, enabling us to take advantage of the natural hierarchy in our separate datasets, and thus to identify, and even to measure potential effects of institutional quality. Since we take into account many individual students characteristics, we are able to obtain an income hierarchy among the different disciplines : students who gr…
THE EVOLUTION OF THE SEWAGE TREATMENT PROCESS IN ROMANIA IN THE LAST 30 YEARS: CASE STUDY RÂMNICU VÂLCEA
2012
The evolution of the sewage treatment process in Romania in the last 30 years: case study Râmnicu Vâlcea. Most studies made at national level in the domain of hydrology target the surface water topic, analyzing the hydrometric and hydrologic characteristics and the quality of the water for certain catchment areas. This paper aims instead the relatively new field of urban hydrology, more exactly the urban wastewater treatment process. The study is based on the observations made in the first half of the year 2010 at the wastewater treatment plant from Râmnicu Vâlcea and on the analysis of some relevant wastewater quality indicators before and after the treatment process for the period between…
Hydrothermal co-liquefaction of sewage sludge and formic acid
2019
The biocrude produced by non-catalytic hydrothermal liquefaction (HTL) has a too high heteroatom content to be used directly as a fuel [1-3]. Several studies found that different H2 initial pressures during HTL experiments were ineffective in improving the biocrude yield [4-6], nevertheless it was observed that higher initial pressures of H2 brought an improvement of the concentration of light compounds in the biocrude, decreasing the average molecular weight of biocrude oil. To date H2 is mainly generated from fossil sources and realization of a possible hydrogen economy from alternative sources presents many challenges. The use of a liquid hydrogen storage media could represent for the HT…
Corporate social irresponsibility & electronic word of mouth : case Volkswagen emissions crisis
2017
Even though corporations’ interest towards corporate social responsibility (CSR) has significantly increased in the last decades, organizations still commit various acts of corporate social irresponsibility (CSI). At the same time the emergence of social media has offered stakeholders interact in ways formerly unimaginable, and the content of these conversations is slipping further away of organizational control. This research participates the theoretical conversations of CSR, CSI and stakeholder research as well as the active stream of social media and electronic word of mouth (eWOM) research. This thesis is a case study researching eWOM related to Volkswagen emissions crisis in 2015. As t…
Optical Monitoring of Microplastics Filtrated from Wastewater Sludge and Suspended in Ethanol.
2021
The abundance of microplastics (MPs) in the atmosphere, on land, and especially in water bodies is well acknowledged. In this study, we establish an optical method based on three different techniques, namely, specular reflection to probe the medium, transmission spectroscopy measurements for the detection and identification, and a speckle pattern for monitoring the sedimentation of MPs filtrated from wastewater sludge and suspended in ethanol. We used first Raman measurements to estimate the presence and types of different MPs in wastewater sludge samples. We also used microscopy to identify the shapes of the main MPs. This allowed us to create a teaching set of samples to be characterized …
Volkswagen Emission Crisis : Managing Stakeholder Relations on the Web
2016
Organizations establish their own profiles at social media sites to publish pertinent information to customers and other stakeholders. During a long and severe crisis, multiple issues may emerge in media interaction. Positive responses and prompt interaction from the official account of e.g. a car manufacturer creates clarity and reduces anxiety among stakeholders. This research targets the Volkswagen 2015 emission scandal that became public on Sept. 18, 2015. We report its main phases over time based on public web information. To better understand the online interaction and reactions of the company, we scrutinized what information was published on VW’s official web sites, Facebook, and Twi…
E-Sports y brecha de género: la percepción de las profesionales españolas
2019
The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…
Alternative measures of body composition and wage premium: New evidence from Indonesia
2019
This paper examines the relationship between body composition and earnings in a developing country setting. We use body mass index, waist circumference and hip circumference. Exploiting the panel structure of our longitudinal survey, we find that along with BMI, waist circumference is related to higher earnings in Indonesia. peerReviewed
