La utilidad de los informes de sostenibilidad en entidades públicas y privadas en Colombia
2021
El aumento en la divulgación de información social y medioambiental (de sostenibilidad) genera preguntas sobre su utilidad y materialidad, lo que implica conocer las expectativas de los stakeholders. El stakeholder engagement permite señalar que la participación de los grupos de interés no solo debe centrarse en la producción de la información en las empresas, sino también en la definición de los marcos y estándares que estructuran estos reportes. Este trabajo busca caracterizar las expectativas y la percepción que tienen diversos stakeholders, sobre la utilidad de los informes de sostenibilidad emitidos por organizaciones públicas y privadas en Colombia. A partir de dos cuestionarios respo…
Inflammatory and cytotoxic responses of an alveolar-capillary coculture model to silica nanoparticles: Comparison with conventional monocultures
2011
Abstract Background To date silica nanoparticles (SNPs) play an important role in modern technology and nanomedicine. SNPs are present in various materials (tyres, electrical and thermal insulation material, photovoltaic facilities). They are also used in products that are directly exposed to humans such as cosmetics or toothpaste. For that reason it is of great concern to evaluate the possible hazards of these engineered particles for human health. Attention should primarily be focussed on SNP effects on biological barriers. Accidentally released SNP could, for example, encounter the alveolar-capillary barrier by inhalation. In this study we examined the inflammatory and cytotoxic response…
The Risk, the Real, and the Impossibility of Life
2017
The discourse of the Matrix not only wakes up philosophy from the slumber they are, but reflects the rise of fears which are proper of a culture, that manipulates anxieties to fix policies otherwise would be rejected. Basically, Neo is subject to an ethical dilemma which means that we are free to make the decision to live in a fake without suffering or in “the real of the dessert” as Morpheus put it. At this extent, if technology is used to protect humankind, Matrix evinces under some circumstances, it can oppress human beings when they renounce to their “free-will”. This chapter not only explored the limitations of the society of risks within liberal thought but taking into consideration t…
Efecto de supresión y mediación en el contexto de la intervención psicosocial: Diferencias, similitudes y ejemplos
2013
ResumenEl presente trabajo compara el efecto mediador y el supresor de una tercera variable. Ambos efectos parcelan la varianza de la variable dependiente (Y). La mediación es la reducción, tras introducir una tercera variable (Z) en el modelo, de la proporción de varianza explicada directamente por la variable independiente (X) en la variable criterio (Y) y la supresión es el incremento de la proporción de varianza explicada directamente por la independiente en la variable criterio, al incluir la tercera variable en el modelo. Se analizan las características y diferencias de cada efecto y se examina en qué situaciones se produce uno u otro. Cada situación, compuesta de tres variables corre…

SECONDARY SCHOOL AND UNIVERSITY STUDENTS’ INTEREST IN SCIENCE SUBJECTS IN CONNECTION TO THE CHOICE OF PROFESSION
2019
One of the most important factors influencing the welfare of the society is the development of science and technology, which in turn depends on scientists and students' science literacy. The aim of the study was to investigate the interest of high school and university students in science subjects, their views on factors that raise interest in subjects and play a determining role in the choice of profession. The questionnaire of Riga secondary school and university students about their interest in science subjects in connection to the choice of their profession was carried out. The results of the survey showed that the majority of university students are interested, or they have moderate i…
Prima della riforma ospedaliera. Il sistema assistenziale di Palermo dai Normanni agli Aragonesi (XI-XV secolo)
2019
Il saggio ricostruisce le origini del sistema assistenziale palermitano nei secoli precedenti la riforma ospedaliera quattrocentesca. Attraverso la rilettura di fonti edite e l'utilizzo di documenti inediti, si rivedranno gli assunti di una storiografia erudita spesso non verificata. Seguendo le molteplici fasi vissute dalla città nel corso dei secoli, verranno distinte le realtà caritative legate all'arrivo e allo stabilizzarsi del potere normanno (secoli XI-XII) da quelle successive (secoli XIII-XV), frutto di dinamiche politiche, sociali e culturali del tutto differenti The essay reconstructs the origins of the Palermo assistance system before the Fifteenth-century hospital reform. Throu…
Chronic Poverty in European Mediterranean Countries
2013
This chapter investigates the characteristics of chronic poverty among youth in Southern European countries. These countries have the highest levels of poverty in Europe and welfare systems unable to smooth social inequalities effectively. The main aim of this chapter is to investigate on how long-lasting poor among the Mediterranean youth differs in socio-demographic and economic characteristics. The intensity of poverty over time is measured by a very recent longitudinal poverty index based on the rationale of cumulative hardship. We tested the effects of many covariates on the incidence and intensity of chronic poverty, controlling for main socio-demographic and economic characteristics,…
Changes in behavioural response of Mediterranean Seabass (Dicenthratus labrax L.) under different feeding distributions
2009
Captive-induced behavioural deviations may involve many aspects of fish behaviour such as swimming activity and enhancement of individual aggressiveness. We studied seabass (Dicentrarchus labrax) behaviour as a function of manual and automatic feeding distribution modes. Under manual mode, the food is distributed over an extended area for a longer period, and its precise location is not always predictable, while with pneumatic automatic feeders, fish receive the same amount of resource, which is concentrated in the same surface area over a shorter period. We compared seabass behaviour under automatic and manual conditions collecting video image recordings before, during, and after feeding d…
Work-life balance e servizi per la prima infanzia. Un’analisi di contesto in tema di welfare locale.
2017
Questo saggio riflette su come le diseguaglianze in tema di genere e classi d’età influenzino l’accesso al mercato del lavoro, ma, soprattutto, la sfera riproduttiva. Maternità e professione si pongono spesso come scelte escludentesi l’un l’altro per l’inadeguatezza dei servizi di cura soprattutto nel Meridione. Il saggio passa in rassegna le leggi che a livello nazionale e regionale hanno cercato di favorire la conciliazione famiglia-lavoro nelle famiglie dual earner. Analizza poi la presenza di tali servizi per l’infanzia in Palermo, negli ultimi anni. Il case study del comune di Palermo evidenzia una generale esiguità dei servizi e una pro- gressiva diminuzione degli asili nido pubblici,…
