Perceived teaching efficacy and coeducational vs. single-sex grouping in physical education teachers
2021
In many countries, sex equality is an essential aim of physical education (PE) curricula, while the PE grouping practices are widely hetero-normative. As far as there is a discrepancy between the curricula and practice, equality will not fully take place. This study examined the associations between PE teachers’ perceived teaching efficacy (student engagement, instruction, class management) and preferences for single-sex (i.e. juridical sex) vs. coeducational grouping in PE. The analysis, based on a cross-sectional online survey of 175 Finnish PE teachers, showed that higher perceived class management was associated with the stronger preferences for single-sex PE. Associations of teacher’s …
Iedzīvotāju telpiskā diferenciācija Rīgas apkaimēs pēc mājās lietotās valodas
2017
Maģistra darba „Iedzīvotāju telpiskā diferenciācija Rīgas apkaimēs pēc mājās lietotās valodas” mērķis ir izpētīt Rīgai raksturīgās iedzīvotāju telpiskās diferenciācijas iezīmes pēc mājās lietotās valodas, izmantojot pieejamos datus un pielietojot datu apstrādes un analīzes metodes. Galvenie jautājumi maģistra darba teorētiskajā daļā saistīti iedzīvotāju telpiskās diferenciācijas un segregācijas izpēti. Pētījuma rezultātā tika raksturotas konstatētās iedzīvotāju diferenciācijas un segregācijas telpiskās izpausmes un likumsakarības, novērtēts to līmenis Rīgā pēc mājās lietotās valodas.
Study of the Stability of Citrate Capped AgNPs in Several Environmental Water Matrices by Asymmetrical Flow Field Flow Fractionation
2021
Asymmetrical flow field-flow fractionation (AF4) coupled to UV-Vis and dynamic light scattering (DLS) detectors in series, was tested for stability studies of dispersions of citrate-capped silver nanoparticles (AgNPs) in several water matrices. The main goal is to provide knowledge to understand their possible behavior in the environment for short times since mixturing (up to 180 min). Ultrapure (UPW), bottled (BW1, BW2), tap (TW), transitional (TrW) and sea water (SW) matrices were assayed. Observations were compatible with the aggregation of AgNPs, a change in the plasmon band and a size growth with time were done. Fractograms showed different evolution fingerprints in the function of the…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
The city management: methodological considerations on multriple criteria techniques for the selection and aggregation of criteria
2012
The scientific community recognizes that factors such as “social cohesion”, “social quality”, “social capital” and other have a strategic role in the evaluation of the en-richment or the impoverishment of society which occurs in urban environment. These factors are used to evaluate the quality of a social system and to discriminate between different policy alternatives in the management of the city. Social cohesion, quality, equity, progress, etc. are aggregate indicators of urban quality, as they incorporate various components related to multiple points of view. The scientific community and some national and international institutions have proposed different sets of indicators for the esti…
Heterogeneity versus Homogeneity in Schools: A Review of the Educational Value of Classroom Interaction
2020
The degree of homogeneity and heterogeneity among schools affects the comprehensiveness and inclusiveness of the school system and the type and scope of classroom interaction. Since the beginning of the 1980s, interest has gradually increased in the effects of homogeneity and heterogeneity of schools on classroom interactions
Soil aggregates, organic matter turnover and carbon balance in a Mediterranean eroded vineyard
2014
The carbon cycle is being affected by the human impacts (Novara et al., 2011; Yan-Gui et al., 2013), and one of those is the intensification in the soil erosion in agriculture land (Cerdà et al., 2009; García Orenes et al., 2009). Vineyards also are affected by the human activities (Fernández Calviño, 2012). Vineyards in Sicily are cultivated on 110.000 ha, 10% of which on >10% slope. Deficiencies of soil organic matter are typical of the semi arid Mediterranean environment especially where traditional intensive cropping practices are adopted (Novara et al., 2012; 2013). These practices in vineyards could lead soil to intensive erosion processes (Novara et al., 2011). The fate of SOC under …
A Long Journey into the Investigation of the Structure–Dynamics–Function Paradigm in Proteins through the Activities of the Palermo Biophysics Group
2022
An overview of the biophysics activity at the Department of Physics and Chemistry Emilio Segrè of the University of Palermo is given. For forty years, the focus of the research has been on the protein structure–dynamics–function paradigm, with the aim of understanding the molecular basis of the relevant mechanisms and the key role of solvent. At least three research lines are identified; the main results obtained in collaboration with other groups in Italy and abroad are presented. This review is dedicated to the memory of Professors Massimo Ugo Palma, Maria Beatrice Palma Vittorelli, and Lorenzo Cordone, which were the founders of the Palermo School of Biophysics. We all have been, directl…
Can the students' career performance be helpful in predicting an increase in universities income?
2013
The students’ academic failure and the delay in obtaining their final degree are a significant issue for the Italian universities and their shareholders. Based on indicators proposed by the Italian Ministry of University, the Italian universities are awarded a financial incentive if they reduce the students’ attrition and failure. In this paper we analyze the students’ careers performance using: 1) aggregate data; 2) individual data. The first compares the performances of the Italian universities using the measures and the indicators proposed by the Ministry. The second analyzes the students’ careers through an indicator based on credit earned by each student in seven academic years. The pr…
Työelämän sukupuolistavat käytännöt sosiaalityössä : diskurssianalyysi Talentia-lehdessä käydystä sosiaalityön ammatillisesta keskustelusta
2010
Tarkastelen Pro-gradu-työssäni suomalaisen sosiaalityön työelämän sukupuolistavia käytäntöjä. Yhdistelen tutkimuksessani työelämän, sosiaalityön ja professioiden tutkimusta sekä naistutkimusta. Sukupuoli on tutkimukseni keskeinen käsite, jonka määrittelen Judith Butleria mukaillen performatiivina, jota tuotetaan arkielämässä jatkuvasti uudestaan. Yhteiskunnan rakenteiden tasolla segregoituminen asettaa naiset ja miehet toimimaan eri aloilla ja tehtävissä. Työelämän sukupuolistavat käytännöt taas toimivat työpaikkojen arkisissa käytännöissä muokaten miehiin ja naisiin kohdistuvia odotuksia, tulkintoja ja yksilöiden käyttäytymistä. Sosiaalityötä lähestyn sekä naisvaltaisten ammattien professi…
