Assessment and intervention issues and models in School Psychology : the case of Europe and North America
As práticas da Psicologia Escolar parecem ser cada vez mais marcadas pelas necessidades de referenciação/diagnóstico
de crianças para o subsistema de educação especial, em detrimento do desenho e implementação de intervenções
dirigidas aos problemas específicos dos alunos. A aparente insatisfação dos psicólogos escolares com essa tendência,
bem como as dificuldades na utilização de modelos categoriais de diagnóstico em contexto escolar, têm dado origem
à progressiva implementação de modelos alternativos de avaliação e intervenção, principalmente de modelos Response
to Intervention, Curriculum-Based Measurement e Problem Solving. A controvérsia quanto à natureza verdadeiramente
alternativa desses modelos parece, no entanto, longe de se esgotar. Neste artigo são discutidas vantagens e limitações
dos diferentes modelos, de acordo com a melhor evidência disponível na literatura, e são ainda equacionadas as suas
implicações nas práticas da Psicologia Escolar. Practices in School Psychology seem to be increasingly restricted to referrals/diagnosis of children for the sub-system

alternative assessment and intervention models, such as Response to Intervention, Curriculum-Based Measurement
and Problem-Solving. However, the controversy about the true alternative nature of these models seems far from
being exhausted. The aim of this paper is to discuss the benefits and limitations of the different models according to

A Comparison of Components of Written Expression Abilities in Learning Disabled and Non-Learning Disabled Students at Three Grade Levels
Although written language plays a critical role in academic success, little empirical evidence exists on the normal development of processes involved in producing written products. Even less is known about the writing performance of LD children. This study empirically compared the written products of LD and normal students at three grade levels on The Test of Written Language. Results showed that LD subjects scored significantly lower than normal subjects on most written expression abilities, especially in the mechanical tasks of spelling, punctuation, and word usage.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
Cascade oxime formation, cyclization to a nitrone, and intermolecular dipolar cycloaddition.
Simple haloaldehydes, including enolisable aldehydes, were found to be suitable for the formation of cyclic products by cascade (domino) condensation, cyclisation, dipolar cycloaddition chemistry. This multi-component reaction approach to heterocyclic compounds was explored by using hydroxylamine, a selection of aldehydes, and a selection of activated dipolarophiles. Initial condensation gives intermediate oximes that undergo cyclisation with displacement of halide to give intermediate nitrones; these nitrones undergo in situ intermolecular dipolar cycloaddition reactions to give isoxazolidines. The cycloadducts from using dimethyl fumarate were treated with zinc/acetic acid to give lactam products and this provides an easy way to prepare pyrrolizinones, indolizinones, and pyrrolo[2,1-a]isoquinolinones. The chemistry is illustrated with a very short synthesis of the pyrrolizidine alkaloid macronecine and a formal synthesis of petasinecine
Monitoreo del progreso del alumno en la identificación de riesgo en la lectura
Este estudo tem por nalidade analisar o uso da monitorização com base no currículo como sistema escolar de identi cação de alunos em risco na leitura, no contexto de um modelo educativo baseado no grau de resposta à intervenção. Realizou-se uma investigação quantitativa em que participaram todos os alunos do 3o ano (82 alunos) de um agrupamento de escolas do norte de Portugal. O tratamento de dados foi feito com recurso à estatística descritiva e inferencial. Destacam-se, entre outras conclusões, a existência de dez alunos em risco na leitura durante todo o ano letivo e o facto de, no nal do 3o ano de escolaridade, a média de resultados dos alunos que nunca estiveram em risco ser superior ao dobro da média de resultados dos alunos que estiveram em risco todo o ano.This study aims to analyze the use of curriculum-based monitoring as a school
system to identify students at risk in reading, in the context of an educational
model based on the degree of response to intervention. A quantitative investigation
was conducted with all third grade students (82 students) from a group of
schools in the north of Portugal. Data processing was done using descriptive and
inferential statistics. Among the conclusions, the following stand out: the existence
of ten students at risk in reading throughout the school year and the fact that, at
the end of the third year of schooling, the mean results of students who were never
at risk was more than double the mean results of students who were at risk for the
entire year.Cette étude a pour but d’analyser l’usage du contôle ayant pour base le coursus

les élèves de CM1 (82 élèves) d’un groupement d’écoles du nord du Portugal. Le
traitement des données a été fait à l’aide de la statistique descriptive et inférentielle.
On souligne, entre autres conclusions, l’existence de dix élèves en risque dans la
lecture pendant toute l’année scolaire et le fait qu’à la fin de la troisièmme année
de scolarité, la moyenne des résultats des élèves n’ayant jamais été en risque soit
supérieur au double de la moyenne des résultats des élèves qui ont été en risque

Plant cell culture technology in the cosmetics and food industries : current state and future trends
The production of drugs, cosmetics, and food which are derived from plant cell and tissue cultures has a long tradition. The emerging trend of manufacturing cosmetics and food products in a natural and sustainable manner has brought a new wave in plant cell culture technology over the past 10 years. More than 50 products based on extracts from plant cell cultures have made their way into the cosmetics industry during this time, whereby the majority is produced with plant cell suspension cultures. In addition, the first plant cell culture-based food supplement ingredients, such as Echigena Plus and Teoside 10, are now produced at production scale. In this mini review, we discuss the reasons for and the characteristics as well as the challenges of plant cell culture-based productions for the cosmetics and food industries. It focuses on the current state of the art in this field. In addition, two examples of the latest developments in plant cell culture-based food production are presented, that is, superfood which boosts health and food that can be produced in the lab or at home
Does Size Matter? The Productivity of Government: Expenditures and the Size of States: Evidence from India
Some politicians argue for the splitting and combining of states to increase government productivity, but there is a dearth of empirical evidence on the optimal size of a state. Using data from Indian states, I test a model of the optimal size of the state. I find that size and preference heterogeneity do not significantly affect the productivity of a state government. However, when states are split up, the productivity of the root state's government is negatively affected. This suggests that there may be a readjustment phase after state reorganisation that brings about this negative effect. It is important to consider this effect when redrawing state borders
Asymmetric Error Correction Models for the Oil-Gasoline Price Relationship
The existing literature on price asymmetries does not systematically investigate the sensitivity of the empirical results to the choice of a particular econometric specification. This paper fills this gap by providing a detailed comparison of the three most popular models designed to describe asymmetric price behaviour, namely asymmetric ECM, autoregressive threshold ECM and ECM with threshold cointegration. Each model is estimated on a common monthly dataset for the gasoline markets of France, Germany, Italy, Spain and UK over the period 1985-2003. All models are able to capture the temporal delay in the reaction of retail prices to changes in spot gasoline and crude oil prices, as well as some evidence of asymmetric behaviour. However, the type of market and the number of countries which are characterized by asymmetric oil-gasoline price relations vary across models. The asymmetric ECM yields some evidence of asymmetry for all countries, mainly at the distribution stage. The threshold ECM strongly rejects the null hypothesis of symmetric price behaviour, particularly in the case of France and Germany. Finally, the ECM with threshold cointegration finds long-run asymmetry for each country in the reaction of retail prices to oil price changes
