The factorial structure of the 41-item version of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a Spanish population of 8 to 12 years-old

On this instrumental study we intend to analyse the factorial structure of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a Spanish sample using exploratory and confirmatory factorial analysis. As a second objective we intend to develop a short form of it for rapid screening and, finally, to analyze the reliabilities of both questionnaires. The SCARED was administered to a community sample of 1,508 children aged between 8 and 12 years. The sample was randomly split using half for the exploratory analysis and the other half for the confirmatory study. Furthermore a reduced version of the SCARED was developed using the SchmidLeiman procedure. Exploratory Factor Analysis yielded a four factor structure comprised of Somatic/panic, Generalized anxiety, Separation anxiety and Social phobia factors This structure was confirmed using Confirmatory Factor Analysis. The four factors, the full scale and the short scale showed good reliabilities. The results obtained seem to indicate that the Spanish version of the SCARED has good internal consistency, and along with other recent results, has a structure of four related factors that replicates the dimensions proposed for anxiety disorders by the DSM-IV-TR

Use of sorghum straw (Sorghum bicolor) for second generation ethanol production: pretreatment and enzymatic hydrolysis

Agronomic biomass yields of forage sorghum BRS 655 presented similar results to other energy crops, producing 9 to 12.6 tons/ha (dry mass) of sorghum straw. The objective of this study was to evaluate the lignocellulosic part of this cultivar in terms of its potential in the different unit processes in the production of cellulosic ethanol, measuring the effects of pretreatment and enzymatic hydrolysis. Three types of pre-treatments for two reaction times were conducted to evaluate the characteristics of the pulp for subsequent saccharification. The pulp pretreated by alkali, and by acid followed by delignification, attained hydrolysis rates of over 90%.

Wet oxidation of recalcitrant lignin waters: Experimental and kinetic studies

The dissertation is based on four articles dealing with recalcitrant lignin water purification. Lignin, a complicated substance and recalcitrant to most treatment technologies, inhibits seriously pulp and paper industry waste management. Therefore, lignin is studied, using WO as a process method for its degradation. A special attention is paid to the improvement in biodegradability and the reduction of lignin content, since they have special importance for any following biological treatment. In most cases wet oxidation is not used as a complete ' mineralization method but as a pre treatment in order to eliminate toxic components and to reduce the high level of organics produced. The combination of wet oxidation with a biological treatment can be a good option due to its effectiveness and its relatively low technology cost. The literature part gives an overview of Advanced Oxidation Processes (AOPs). A hot oxidation process, wet oxidation (WO), is investigated in detail and is the AOP process used in the research. The background and main principles of wet oxidation, its industrial applications, the combination of wet oxidation with other water treatment technologies, principal reactions in WO, and key aspects of modelling and reaction kinetics are presented. There is also given a wood composition and lignin characterization (chemical composition, structure and origin), lignin containing waters, lignin degradation and reuse possibilities, and purification practices for lignin containing waters. The aim of the research was to investigate the effect of the operating conditions of WO, such as temperature, partial pressure of oxygen, pH and initial concentration of wastewater, on the efficiency, and to enhance the process and estimate optimal conditions for WO of recalcitrant lignin waters. Two different waters are studied (a lignin water model solution and debarking water from paper industry) to give as appropriate conditions as possible. Due to the great importance of re using and minimizing the residues of industries, further research is carried out using residual ash of an Estonian power plant as a catalyst in wet oxidation of lignin-containing water. Developing a kinetic model that includes in the prediction such parameters as TOC gives the opportunity to estimate the amount of emerging inorganic substances (degradation rate of waste) and not only the decrease of COD and BOD. The degradation target compound, lignin is included into the model through its COD value (CODligning). Such a kinetic model can be valuable in developing WO treatment processes for lignin containing waters, or other wastewaters containing one or more target compounds. In the first article, wet oxidation of "pure" lignin water was investigated as a model case with the aim of degrading lignin and enhancing water biodegradability. The experiments were performed at various temperatures (110 -190°C), partial oxygen pressures (0.5 -1.5 MPa) and pH (5, 9 and 12). The experiments showed that increasing the temperature notably improved the processes efficiency. 75% lignin reduction was detected at the lowest temperature tested and lignin removal improved to 100% at 190°C. The effect of temperature on the COD removal rate was lower, but clearly detectable. 53% of organics were oxidized at 190°C. The effect of pH occurred mostly on lignin removal. Increasing the pH enhanced the lignin removal efficiency from 60% to nearly 100%. A good biodegradability ratio (over 0.5) was generally achieved. The aim of the second article was to develop a mathematical model for "pure" lignin wet oxidation using lumped characteristics of water (COD, BOD, TOC) and lignin concentration. The model agreed well with the experimental data (R2 = 0.93 at pH 5 and 12) and concentration changes during wet oxidation followed adequately the experimental results. The model also showed correctly the trend of biodegradability (BOD/COD) changes. In the third article, the purpose of the research was to estimate optimal conditions for wet oxidation (WO) of debarking water from the paper industry. The WO experiments were' performed at various temperatures, partial oxygen pressures and pH. The experiments showed that lignin degradation and organics removal are affected remarkably by temperature and pH. 78-97% lignin reduction was detected at different WO conditions. Initial pH 12 caused faster removal of tannins/lignin content; but initial pH 5 was more effective for removal of total organics, represented by COD and TOC. Most of the decrease in organic substances concentrations occurred in the first 60 minutes. The aim of the fourth article was to compare the behaviour of two reaction kinetic models, based on experiments of wet oxidation of industrial debarking water under different conditions. The simpler model took into account only the changes in COD, BOD and TOC; the advanced model was similar to the model used in the second article. Comparing the results of the models, the second model was found to be more suitable for describing the kinetics of wet oxidation of debarking water. The significance of the reactions involved was compared on the basis of the model: for instance, lignin degraded first to other chemically oxidizable compounds rather than directly to biodegradable products. Catalytic wet oxidation of lignin containing waters is briefly presented at the end of the dissertation. Two completely different catalysts were used: a commercial Pt catalyst and waste power plant ash. CWO showed good performance using 1 g/L of residual ash gave lignin removal of 86% and COD removal of 39% at 150°C (a lower temperature and pressure than with WO). It was noted that the ash catalyst caused a remarkable removal rate for lignin degradation already during the pre heating for `zero' time, 58% of lignin was degraded. In general, wet oxidation is not recommended for use as a complete mineralization method, but as a pre treatment phase to eliminate toxic or difficultly biodegradable components and to reduce the high level of organics. Biological treatment is an appropriate post treatment method since easily biodegradable organic matter remains after the WO process. The combination of wet oxidation with subsequent biological treatment can be an effective option for the treatment of lignin containing waters.

Forest Biomass Resources and Technological Prospects for the Production of Second-generation Biofuels in Finland by 2020

Introduction of second-generation biofuels is an essential factor for meeting the EU’s 2020 targets for renewable energy in the transport sector and enabling the more ambitious targets for 2030. Finland’s forest industry is strongly involved in the development and commercialising of second-generation biofuel production technologies. The goal of this paper is to provide a quantified insight into Finnish prospects for reaching the 2020 national renewable energy targets and concurrently becoming a large-scale producer of forest biomass based second-generation biofuels feeding the increasing demand in European markets. The focus of the paper is on assessing the potential for utilising forest biomass for liquid biofuels up to 2020. In addition, technological issues related to the production of second-generation biofuels were reviewed. Finland has good opportunities to realise a scenario to meet 2020 renewable energy targets and for large-scale production of wood based biofuels. In 2020, biofuel production from domestic forest biomass in Finland may reach nearly a million ton (40 PJ). With the existing biofuel production capacity (20 PJ/yr) and national biofuel consumption target (25 PJ) taken into account, the potential net export of biofuels from Finland in 2020 would be 35 PJ, corresponding to 2–3% of European demand. Commercialisation of second-generation biofuel production technologies, high utilisation of the sustainable harvesting potential of Finnish forest biomass, and allocation of a significant proportion of the pulpwood harvesting potential for energy purposes are prerequisites for this scenario. Large-scale import of raw biomass would enable remarkably greater biofuel production than is described in this paper.

Developing markets of energy biomass – local and global perspectives

The thesis explores global and national-level issues related to the development of markets for biomass for energy. The thesis consists of five separate papers and provides insights on selected issues. The aim of Paper I was to identify methodological and statistical challenges in assessing international solid and liquid biofuels trade and provide an overview of the Finnish situation with respect to the status of international solid and liquid biofuels trade. We found that, for the Finnish case, it is possible to qualify direct and indirect trade volumes of biofuels. The study showed that indirect trade of biofuels has a highly significant role in Finland and may be a significant sector also in global biofuels trade. The purpose of Paper II was to provide a quantified insight into Finnish prospects for meeting the national 2020 renewable energy targets and concurrently becoming a largescale producer of forest-biomass-based second-generation biofuels for feeding increasing demand in European markets. We found that Finland has good opportunities to realise a scenario to meet 2020 renewable energy targets and for large-scale production of wood-based biofuels. The potential net export of transport biofuels from Finland in 2020 would correspond to 2–3% of European demand. Paper III summarises the global status of international solid and liquid biofuels trade as illuminated by several separate sources. International trade of biofuels was estimated at nearly 1 EJ for 2006. Indirect trade of biofuels through trading of industrial roundwood and material by-products comprises the largest proportion of the trading, with a share of about two thirds. The purpose of Paper IV was to outline a comprehensive picture of the coverage of various certification schemes and sustainability principles relating to the entire value-added chain of biomass and bioenergy. Regardless of the intensive work that has been done in the field of sustainability schemes and principles concerning use of biomass for energy, weaknesses still exist. The objective of Paper V was to clarify the alternative scenarios for the international biomass market until 2020 and identify the underlying steps needed toward a wellfunctioning and sustainable market for biomass for energy purposes. An overall conclusion drawn from this analysis concerns the enormous opportunities related to the utilisation of biomass for energy in the coming decades.

Mellom tradisjon og spel : didaktikk for tekstil folkekunst

Denne avhandlinga er resultatet av eit behov for å forske på og utvikle ein didaktikk for tekstilfaget ved Folkekunststudiet, Institutt for folkekultur, Høgskolen i Telemark, Noreg. Studiet med folkekunst som fagfelt er eit relativt ungt studium på høgskolen, som vart etablert i 1984. Problemstillinga i denne avhandlinga er korleis ein kan utvikle ein forskingsbasert didaktikk der dei grunnleggjande prinsippa som særmerkjer den tradisjonelle folkekunsten, vert tekne vare på. I arbeidet med avhandlinga har eg prøvd på å klårgjere problemstillinga ut frå ulike perspektiv. Forskingsarbeidet har fokus på kommunikasjon og arbeidsmåtar i ljos av ulike teoriar. Det er ei hermeneutisk tilnærming som er vald for den didaktiske forståinga. Det fyrste drøftingstemaet har søkjeljos på kommunikasjon og dialog ved vidareføring av tekstil folkekunst. Både estetiske, teoretiske, praktiske og sosiale aspekt er nedfelte i læreplanen for studiet og skal utgjere grunnlaget for kommunikasjon og arbeidsmåtar. I den skapande og kopierande prosessen er det utvikla språklege reiskapar for både den sosiale og den estetiske sida der den teoretiske og praktiske faktoren er integrert. Møte med døme på tekstile tradisjonar så vel som praktisk forming av tekstilar har ført til refleksjon og dialog som involverer kontemplasjon, korrespondens og imaginasjon. Det andre temaet som er drøfta, er vidareføring av tradisjonelt visuelt formspråk. Her er merksemda retta mot kva som har skjedd formalt med ei gruppe tradisjonelle formelement i tekstilar i den institusjonelle vidareføringa over eit lengre tidsperspektiv. Resultatet syner at mange tradisjonelle formelement er borte frå den institusjonelle produksjonen. Formelementa kan ha fått ei meir naturalistisk utforming, eller dei er overførte til andre tradisjonelle tekstilteknikkar enn dei som var utgangspunktet. Rombeforma i den institusjonelle produksjonen er utført i færre variasjonar og kombinasjonar enn i den tradisjonelle produksjonen. Konklusjonen på drøftingstemaet er at spelereglar og spatialitet i høve til den formale komponenten i utvalet med tradisjonelle tekstilar ikkje er vidareført i alle gruppene av institusjonelle produkt. Resultatet kan få innverknad og fylgjer for utforming av ein framtidig didaktikk for faget. Arbeidsmåte og erfaring frå vidareføring av tekstile tradisjonar er det tredje temaet som er drøfta i avhandlinga. Kopiering og skapande prosessar er arbeidsmåtar som er brukte ved studiet i dag, og dei utgjer grunnlag for drøftingar i relasjon til vidareføring og erfaring. Konklusjonen er at i den skapande prosessen korrigerer tradisjonen utforminga, medan i kopiprosessen er eigen stilvilje og improvisering resultat av prosessane. Personar som deltek i prosessane, har sett seg sjølve og si historiske forankring inn i spelet, der visuelt og verbalt språk er resultat av integrasjon av tradisjonar. Dei tre drøftingstemaa utgjer grunnlaget for at didaktikk for folkekunst og tekstil kan bli intersubjektiv forståing av kva ein didaktikk for vidareføring av folkekunst med vekt på tekstil kan vere i utdanninga i dag. Indre og ytre dialog i skapande og kopierande prosessar femner om estetiske, materielle og tekniske faktorar sett i høve til spelereglar, spelerom, spatialitet og samspel i møte med tekstile tradisjonar. Samla utgjer det ein forskingsbasert didaktikk for faget der den overordna intensjonen er samtykke mellom tradisjon og spel.

Obstetric outcomes in the second birth of women with a previous caesarean delivery: a retrospective cohort study from Peru

PURPOSE: To examine obstetric outcomes in the second birth of women who had undergone a previous cesarean delivery. METHODS: This was a large hospital-based retrospective cohort study. We included pregnant women who had a previous delivery (vaginal or cesarean) attending their second birth from 2001 to 2009. Main inclusion criteria were singleton pregnancies and delivery between a gestation of 24 and 41 weeks. Two cohorts were selected, being women with a previous cesarean delivery (n=7,215) and those with a vaginal one (n=23,720). Both groups were compared and logistic regression was performed to adjust for confounding variables. The obstetric outcomes included uterine rupture, placenta previa, and placental-related complications such as placental abruption, preeclampsia, and spontaneous preterm delivery. RESULTS: Women with previous cesarean delivery were more likely to have adverse outcomes such as uterine rupture (OR=12.4, 95%CI 6.8-22.3), placental abruption (OR=1.4, 95%CI 1.1-2.1), preeclampsia (OR=1.4, 95%CI 1.2-1.6), and spontaneous preterm delivery (OR=1.4, 95%CI 1.1-1.7). CONCLUSIONS: Individuals with previous cesarean section have adverse obstetric outcomes in the subsequent pregnancy, including uterine rupture, and placental-related disorders such as preeclampsia, spontaneous preterm delivery, and placental abruption.

Two-dimensional atom localization and Raman cooling of tripod-type atoms

Both atom localization and Raman cooling, considered in the thesis, reflect recent progress in the area of all-optical methods. We focus on twodimensional (2D) case, using a four-level tripod-type atomic scheme for atom localization within the optical half-wavelength as well as for efficient subrecoil Raman cooling. In the first part, we discuss the principles of 1D atom localization, accompanying by an example of the measurement of a spontaneously-emitted photon. Modifying this example, one archives sub-wavelength localization of a three-level -type atom, measuring the population in its upper state. We go further and obtain 2D sub-wavelength localization for a four-level tripod-type atom. The upper-state population is classified according to the spatial distribution, which in turn forms such structures as spikes, craters and waves. The second part of the thesis is devoted to Raman cooling. The cooling process is controlled by a sequence of velocity-selective transfers from one to another ground state. So far, 1D deep subrecoil cooling has been carried out with the sequence of square or Blackman pulses, applied to -type atoms. In turn, we discuss the transfer of atoms by stimulated Raman adiabatic passage (STIRAP), which provides robustness against the pulse duration if the cooling time is not in any critical role. A tripod-type atomic scheme is used for the purpose of 2D Raman cooling, allowing one to increase the efficiency and simplify the realization of the cooling.

Selectivity of glyphosate in tank mixtures for RR soybean in sequential applications with mixtures only in the first or second application

Tank mixtures among herbicides of different action mechanisms might increase weed control spectrum and may be an important strategy for preventing the development of resistance in RR soybean. However, little is known about the effects of these herbicide combinations on soybean plants. Hence, two experiments were carried out aiming at evaluating the selectivity of glyphosate mixtures with other active ingredients applied in postemergence to RR soybean. The first application was carried out at V1 to V2 soybean stage and the second at V3 to V4 (15 days after the first one). For experiment I, treatments (rates in g ha-1) evaluated were composed by two sequential applications: the first one with glyphosate (720) in tank mixtures with cloransulam (30.24), fomesafen (125), lactofen (72), chlorimuron (12.5), flumiclorac (30), bentazon (480) and imazethapyr (80); the second application consisted of isolated glyphosate (480). In experiment II, treatments also consisted of two sequential applications, but tank mixtures as described above were applied as the second application. The first one in this experiment consisted of isolated glyphosate (720). For both experiments, sequential applications of glyphosate alone at 720/480, 960/480, 1200/480 and 960/720 (Expt. I) or 720/480, 720/720, 720/960 and 720/1200 (Expt. II) were used as control treatments. Applications of glyphosate tank mixtures with other herbicides are more selective to RR soybean when applied at younger stages whereas applications at later stages might cause yield losses, especially when glyphosate is mixed with lactofen and bentazon.

Att tala om det osägbara : Nicolaus Cusanus cirkulära filosofi i verket De coniecturis med särskild hänsyn till Nelson Pikes tankar om unio mystica

In my dissertation called Speaking of the unsayable: The circular philosophy of Nicholas of Cusa in his work De coniecturis, I presuppose an internal (conceptual) relation between the personal experience of God of Nicholas of Cusa (1401-64) in 1438 and, on the other hand, his philosophy. I hence try to describe the precise character of this relation. Referring to the Norwegian scholars Egil Wyller and Viggo Rossvær, I assume that there is a circularity in Cusanus’ philosophy which appears as self-references (= a sentence refers to itself: A is explained by B and B is explained by A). Wyller finds three phases in the thought of Cusanus (1. De docta ignorantia I-III, 2. De coniecturis I-II, 3. all subsequent works). Rossvær finds it impossible to presuppose certain phases, as the philosophy of Cusanus continuously proceeds and remains open to new ideas. As Cusanus however treats his experience of God far more consciously in his second work De coniecturis than in De docta ignorantia, I find it possible to distinguish between the earlier Cusanus (De docta ignorantia including his earlier works) and the later Cusanus (De coniecturis, about 1444, as well as the following works). Cusanus creates a philosophy of language in outline expressed in De coniecturis, in which he presents two concepts of necessity, i.e. absolute necessity and logical, or reasonable, necessity. These are interrelated in the sense that the mind, or the self, logically affirms the absolute, or unsayable, necessity, which shows itself in the mind and which the mind affirms conjecturally. The endeavour conceptually to understand absolute necessity implies intuitive (or intellectual) contemplation, or vision (investigatio symbolica), in which the four mental unities (the absolute, the intellectual, the rational and the sensuous) work together according to the rules described in De coniecturis. In De coniecturis Cusanus obviously turns from a negative concept of the unsayable to a paradigmatic, which implies that he looks for principles of speaking of the unsayable and presents the idea of a divine language (divinaliter). However, he leaves this idea behind after De coniecturis, although he continues to create new concepts of the unsayable and incomprehensible. The intellectual language of absolute seeing is expressed in the subjunctive, i.e. conditionally. In order to describe the unsayable, Cusanus uses tautologies, the primary one of which is a concept of God, i.e. non aliud est non aliud quam non aliud (the non-other is non-other than the nonother). Wyller considers this the crucial point of the philosophy of Cusanus (De non aliud), described by the latter as the definition of definitions, i.e. the absolute definition. However, this definition is empty regarding its content. It demonstrates that God surpasses the coincidence of opposites (coincidentia oppositorum) and that he is “superunsayable” (superineffabilis), i.e. he is beyond what can be conceived or said. Nothing hence prevents us from speaking of him, provided that he is described as unsayable (= the paradigmatic concept of the unsayable). Here the mode of seeing is decisive. Cusanus in this context (and especially in his later literary production) uses modalities which concern possibility and necessity. His aim is to conduct any willing reader ahead on the way of life (philosophia mentalis). In De coniecturis II he describes the notion of human self-consciousness as the basis of spiritual mutuality in accordance with the humanistic tradition of his time. I mainly oppose the negatively determined concept of Christian mysticism presented by the German philosopher Kurt Flasch and prefer the presentation of Burkhard Mojsisch of the translogical and conjectural use of language in De coniecturis. In particular, I take account of the Scandinavian research, basically that of Johannes Sløk, Birgit H. Helander, Egil Wyller and Viggo Rossvær, who all consider the personal experience of God described by Cusanus a tacit precondition of his philosophy.

The false promises of the (second) Washington consensus: evidence from Latin America and the Caribbean (1990-2003)

The objective of this paper is twofold. Firstly, we show how, and to what extent, Latin American and Caribbean countries applied the precepts of the second Washington consensus, i.e. a consensus which stresses the capital account liberalization. Secondly, we highlight the effects of this set of reforms on their economies. Thus, we show that countries having most scrupulously followed these recommendations did not experience better economic results. On the contrary, their situation as regards inequality and debt is getting worse than others.
