Meta-parenting as predictor of efficient parenting
No full textMetastarševstvo je razmeroma nov, večdimenzionalen konstrukt, ki pod skupen pojem združuje namerne misli starša o svojem otroku in vzgoji. Gre za zavesti dostopne misli, ki jih posameznik lahko obvladuje in prilagaja, zato metastarševstvo predstavlja pomembno miselno orodje starša, s katerim lahko uspešnejše uravnava svoje vedenje in ga prilagaja nenehno spreminjajočemu se kontekstu vzgoje. V magistrskem delu me je zanimalo, kako se metastarševstvo izraža na vzorcu slovenskih mam, katere demografske značilnosti ga napovedujejo in ali je metastarševstvo pomemben napovednik vzgojnih vedenj starša. V študiji je sodelovalo 210 slovenskih mam otrok, starih od tri do šest let. Izpolnile so slovenski prevod vprašalnika metastarševstva (MPPQ) in slovenski prevod lestvice multidimenzionalne ocene starševstva (MAPS). Rezultati so pokazali, da je izraznost metastarševstva na slovenskem vzorcu nizka do srednje visoka. Pokazalo se je tudi, da so starejše mame poročale o nekoliko nižji, a pomembno različni meri izraženosti metastarševstva kakor mlajše mame. Med pomembnimi napovedniki pozitivnih vzgojnih vedenj se je pokazala le komponenta reševanje problemov, med napovedniki negativnih vzgojnih vedenj pa kombinacija komponent ruminacija, ocenjevanje, refleksija in nove ideje. Kaže se, da je za izraženost vzgojnih vedenj bolj pomembna izraženost kombinacije več komponent kakor izraženost ene same komponente metastarševstva. Slednje je še posebej pomembno pri načrtovanju intervencij za razvijanje metastarševstva, ki staršu omogoča uspešnejše uravnavanje lastnega vedenja in s tem prilagajanje nenehno spreminjajočemu se kontekstu vzgoje.Meta-parenting is a relatively new, multidimensional construct that brings together a parent\u27s intentional thoughts about the development of their child and upbringing under a common concept. It describes thoughts that are consciously accessible and that everyone can control and adapt. In that regard, meta-parenting is a cognitive tool for parents with which they can more successfully regulate their behavior and adapt it to the constantly changing context of upbringing. In my master thesis, I was interested in how meta-parenting is expressed in a sample of Slovenian mothers, which demographic characteristics predict it, and whether meta-parenting is an important predictor of parental educational behaviors. In the study participated 210 Slovenian mothers of children between 3 and 6 years of age. They completed the Slovenian translation of the meta-parenting profile questionnaire (MPPQ) and the Slovenian translation of the multidimensional assessment parenting scale (MAPS). The results showed that the expression of meta-parenting, in the sample of Slovenian mothers, is low to medium-high. It has also been shown that older mothers reported slight, but significantly lower expression of meta-parenting, than younger mothers. Among the important predictors of positive parenting behaviors, only the component of problem-solving was found, and among the predictors of negative parenting behaviors, a combination of components ruminating, assessment, reflecting, and new ideas were found. It seems that a combination of several components is more important for the expression of parenting behaviors, than is a high expression of only one meta-parenting component. This finding is especially important in the planning of interventions for the development of meta-parenting, which enables the parent to regulate their behavior more successfully and thus adapt to the constantly changing context of education
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Thirst beats hunger – declining hydration during drought prevents carbon starvation in Norway spruce saplings
No full textDrought-induced tree mortality results from an interaction of several mechanisms. Plant water and carbon relations are interdependent and assessments of their individual contributions are difficult. Because drought always affects both plant hydration and carbon assimilation, it is challenging to disentangle their concomitant effects on carbon balance and carbon translocation. Here, we report results of a manipulation experiment specifically designed to separate drought effects on carbon and water relations from those on carbon translocation. In a glasshouse experiment, we manipulated the carbon balance of Norway spruce saplings exposed to either drought or carbon starvation (CO2 withdrawal), or both treatments, and compared the dynamics of carbon exchange, allocation and storage in different tissues. Drought killed trees much faster than did carbon starvation. Storage C pools were not depleted at death for droughted trees as they were for starved, well-watered trees. Hence drought has a significant detrimental effect on a plant’s ability to utilize stored carbon. Unless they can be transported to where they are needed, sufficient carbon reserves alone will not assure survival of a drought except under specific conditions, such as moderate drought, or in species that maintain plant water relations required for carbon re-mobilization
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Large carbon uptake by an unmanaged 250-year-old deciduous forest in Central Germany
No full textUnmanaged forests at a late stage of successional development are considered to be insignificant as carbon sinks, since in theory, assimilation is thought to be balanced by respiration. However, little experimental evidence for this hypothesis exists so far for forests at the ecosystem level. Therefore, we performed continuous eddy covariance measurements of carbon dioxide over an unmanaged beech forest in the Hainich National Park in Central Germany as part of the EU project CARBOEUROFLUX. This forest shows typical characteristics of an 'advanced' forest with large dead wood pools, a diverse stand structure and a wide tree age class distribution, up to 250 years. This forest was a large carbon sink over 2 years, with 494 g C m(-2) per year in 2000 and 490 g C m(-2) per year in 2001. Daytime summer fluxes were strongly controlled by photosynthetic photon flux density (R-2 = 0.7-0.9), with minor effects of the ratio of diffuse to total downward radiation or the vapor pressure deficit. Nighttime CO2 fluxes were mainly controlled by soil temperature (R-2 = 0.8) and soil moisture. In addition, high nighttime CO2 fluxes (4-6 mumol m(-2) s(-1)) were found directly before and during bud break in spring as well as just after leaf fall of both years (2000 and 2001), reflecting stand physiology corresponding to phenological changes, independent of soil temperature. Additional wind profile measurements at five heights within the canopy revealed a decoupling of above and below canopy air flow under conditions of low friction velocity (u* < 0.4 m s(-1)), probably indicating down slope drainage. In conclusion, unmanaged forests at a comparatively late stage of successional development can still act as significant carbon sinks with large implications for forest management practice and negotiations about biological sinks within the Kyoto Protocol.

Forest and agricultural land-use-dependent CO2 exchange in Thuringia, Germany
No full textEddy covariance was used to measure the net CO2 exchange (NEE) over ecosystems differing in land use (forest and agriculture) in Thuringia, Germany. Measurements were carried out at a managed, even-aged European beech stand (Fagus sylvatica, 70-150 years old), an unmanaged, uneven-aged mixed beech stand in a late stage of development (F. sylvatica, Fraxinus excelsior, Acer pseudoplantanus, and other hardwood trees, 0-250 years old), a managed young Norway spruce stand (Picea abies, 50 years old), and an agricultural field growing winter wheat in 2001, and potato in 2002. Large contrasts were found in NEE rates between the land uses of the ecosystems. The managed and unmanaged beech sites had very similar net CO2 uptake rates (similar to-480 to -500 g C m(-2) yr(-1)). Main differences in seasonal NEE patterns between the beech sites were because of a later leaf emergence and higher maximum leaf area index at the unmanaged beech site, probably as a result of the species mix at the site. In contrast, the spruce stand had a higher CO2 uptake in spring but substantially lower net CO2 uptake in summer than the beech stands. This resulted in a near neutral annual NEE (-4 g C m(-2) yr(-1)), mainly attributable to an ecosystem respiration rate almost twice as high as that of the beech stands, despite slightly lower temperatures, because of the higher elevation. Crops in the agricultural field had high CO2 uptake rates, but growing season length was short compared with the forest ecosystems. Therefore, the agricultural land had low-to-moderate annual net CO2 uptake (-34 to -193 g C m(-2)), but with annual harvest taken into account it will be a source of CO2 (+97 to +386 g C m(-2)). The annually changing patchwork of crops will have strong consequences on the regions' seasonal and annual carbon exchange. Thus, not only land use, but also land-use history and site-specific management decisions affect the large-scale carbon balance. [References: 39
