Systematic review and exploratory meta-analysis of the efficacy, safety, and biological effects of psychostimulants and atomoxetine in patients with …
2019
ObjectiveOur aim was to summarize the efficacy and safety of atomoxetine, amphetamines, and methylphenidate in schizophrenia.MethodsWe undertook a systematic review, searching PubMed/Scopus/Clinicaltrials.gov for double-blind, randomized, placebo-controlled studies of psychostimulants or atomoxetine in schizophrenia published up to 1 January 2017. A meta-analysis of outcomes reported in two or more studies is presented.ResultsWe included 22 studies investigating therapeutic effects of stimulants (k=14) or measuring symptomatic worsening/relapse prediction after stimulant challenge (k=6). Six studies of these two groups plus one additional study investigated biological effects of psychostimu…
On overall sampling plan for small area estimation
2017
The time and budget restrictions in survey sampling can impose limits on the area sample sizes. This may reduce the possibility to obtain area-specific and population parameters estimates with adequate precision. Market research companies and institutes for producing official statistics face frequently this problem. Various models and methods for small area estimation (SAE) have been developed to solve this problem. The sample allocation must support the selected model and method to ensure efficient estimation and must be implemented in the design phase of the survey. The proposed allocation is developed by incorporating auxiliary information, a model, and an estimation method. The estimate…

Why Use Interactive Multi-Objective Optimization in Chemical Process Design?
2008
Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…
Competencia Científica y Resolución de Problemas de Física
2020
Resumen Impulsar y desarrollar la competencia científica entre los estudiantes que cursan materias como la Física, es un objetivo contemplado actualmente de forma explícita en la mayoría de los currículos escolares y es compartido por muchos expertos en Didáctica de las Ciencias Experimentales. Sin embargo, cuando se trata este tema con el profesorado de ciencias, suele hacerse ignorando los contenidos concretos de la materia a enseñar, con lo cual, los profesores difícilmente pueden trasladar a sus clases aquello que les ha sido expuesto en términos demasiado generales o abstractos. En nuestra opinión, si realmente se quiere impulsar y desarrollar la competencia científica, ello ha de hace…
Depression and Sequential Decision-Making Revisited
2019
Background: The effect of depression on decision-making is an important but still an unsettled issue. Although most studies have reported that clinically depressed participants show worse performance, there are also studies that have shown no or even positive effects. Specifically, von Helversen et al. (2011) were able to document a positive effect of depression on task performance in a sequential decision-making task called the secretary problem (SP). Here, we (1) aimed to replicate this study in an extended version using more trials and (2) modified it by including an additional condition in which negative feedback was given. Method: Eighty-two participants took part. They were split into…
Lietu interneta drošības riski saimniecības un viedajās ierīcēs
2017
Lietu internets tiek attiecināts uz ierīcēm, kuras var savienot ar internetu, un kuras atvieglo cilvēku ikdienu. Šādas ierīces var būt gan mašīnas, gan ledusskapji. Šīs ierīču skaits pēdējo gadu laikā strauji pieaug. Taču līdz ar to pieaug arī kibernoziedznieku uzbrukumi lietu internetam, jo vairums ierīču ir nedrošas un ar lielām drošības un privātumu problēmām. Bakalaura darba ietvaros tiek apskatīts, kas ir lietu internets, tā darbības principi, kā arī drošības problēmas, kas ir saistītas ar saimniecības un viedajām ierīcēm. Tāpat tiek veikta aptauja, lai noskaidrotu cilvēku viedokli par lietu interneta un tā problēmām. Tiek apskatītas vairākas lietu interneta ierīces un to lietotnes, un…

The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality
2010
A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…
