IMPLICATION OF PROBLEM BASED INSTRUCTION (PBI) TOWARD STUDENT’S ABILITY IN SOLVING OF ENVIRONMENTAL POLLUTION PROBLEMS
No full textThe student’s Ability to solve problems in daily life is considered low. Though the
problem of environmental pollution due to organic waste requires problem solving
ability to critically and creatively. In the world of education, problem-solving skills can
be taught to students through the model of Problem Based Instruction (PBI). This
research purposed to determine the implication of Problem Based Instruction (PBI)
model toward student’s ability in solving of environmental pollution problems. This
research was a Pre Experimental Design using the One Group Pretest-Posttest Design.
The research was done at SMA Negeri 1 Lamongan on January to July at class X with
sample 7 regular classroom. Collected data of the student’s ability to solve problems
using pretest and posttest methods of assessment with average reliability of the
instrument was 0.78, as well as observatory method to observe the feasibility of student
activities. The result of test data were analyzed using the technique of Spearman rank
correlation with α=5% followed by calculating the determination coefficient, while the
observations data were analyzed by descriptive quantitatively. The results of research
showed that students’ ability to formulate the problem, determine the hypothesis and
research variables was less than 20%, however there are positive implication and
significant between implementation of PBI models for students’ ability in solving
environmental pollution problems by 98,01%, with value of RS=0,99 (very high) and ZH

Analyzing Brazilian markets using the Global VAR & IIS Approach
No full textThis thesis consists of three chapters. The chapters can be read separately, ie there is no predetermined reading order. However, the suggested order follows a linear evolution of the theme. This work expands the work of Barbosa (2017), in his study the author establishes a model for the Brazilian market taking into account the interdependencies between regions using the Global VAR (GVAR) methodology, and uses this model to estimate the elasticity of regional employment in relation to the country’s economic activity. In this study we expand the Barbosa (2017) model on several fronts. First, the study addresses the use of different weight matrices. Traditionally, the weight matrix used in the literature is based on trade weights and bilateral trade between two countries. Barbosa (2017) proposes a weight matrix based on connections between regions, this study in its turn expands these weight matrix allowing the weight matrix to be based not only on connections between regions but also on macroeconomic variables of each region such as GDP, GDP per capita and population. A second innovation is made with the proposal of a new econometric model. This new econometric model is built from the Global VAR model, which is expanded through a saturation with impulse indicators (henceforth called GVAR-IIS). It is worth mentioning that the hypothesis of weak exogeneity remains a requirement for the validity of the GVAR-IIS. For validation of weak exogeneity, the study applies not only the classical tests of weak exogeneity proposed by Granger and Lin (1995) but expands the tests by applying the concept of separability proposed by Hecq et al. (2002). The first part of the study analyzes the original model proposed by Barbosa (2017) using a weight matrix based on connections between cities. The database is expanded to include the period of forecasts that took place between 2016 and 2018. In this chapter we assess how the forecasts behave in the face of the scenario, we also assess the resilience of the regions and the heterogeneity of the responses. In the second part, the GVAR model proposed by Barbosa (2017) is saturated with impulse indicators, this new model is referred as GVAR-IIS. The chapter proposes an estimation procedure for the GVARIIS. The Chapter also presents an empirical exercise in which the new GVAR-IIS model is evaluated together with other models to assess its predictive power. To validate the hypotheses of weak exogeneity, the classical tests proposed by Granger and Lin (1995) are carried out, in which an innovation is the use of the concept of separability proposed by Hecq et al. (2002) to validate the hypothesis of weak exogeneity. Finally, in the third part, the GVAR-IIS model developed in the previous chapter is used together with a weight.Este trabalho utiliza um modelo para o mercado Brasileiro levando em conta as interdependências entre as regiões utilizando a metodologia do Global VAR (GVAR), o estudo é dividido em 3 partes. A primeira parte do estudo analisa o modelo original proposto por (Barbosa, 2017) utilizando uma matriz de peso baseada nas conexões entre cidades. A base de dados é expandida para contemplar o período de previsões ocorridas entre 2016 e 2018. Neste capitulo avaliamos como as previsões se comportam frente ao cenário ocorrido bem como avaliamos a resiliência das regiões e a heterogeneidade das respostas. Na segunda parte, o modelo GVAR é saturado com a indicadoras de impulso, sendo este novo modelo referenciado como GVAR-IIS. O capitulo propõe um procedimento de estimação para o GVAR-IIS. O Capitulo apresenta também um exercício empírico no qual o novo modelo GVAR-IIS é avaliado juntamente com outros modelos para avaliação do seu poder preditivo. Para validação das hipóteses de exogeneidade fraca é realizado os testes clássicos propostos por Granger (1995), em sendo que uma inovação é a utilização do conceito de separabilidade proposto por Hecq (2002) para validação da hipóteses de exogeneidade fraca. Por fim, na terceira parte, o modelo GVAR-IIS desenvolvido no capitulo anterior é utilizado juntamente com uma matriz de pesos baseado na conexões entre cidades ponderada com informações do PIB per-capta. O capitulo avalia a performance de previsão do modelo GVAR-IIS, juntamente com a matriz de conexões, em um cenário de especificação incorreta
Interconnecting Governments, Businesses and Citizens: A Comparison of Two Digital Infrastructures
No full textPublic and private organizations in various areas are setting up digital Information Infrastructures (IIs) for interconnecting government, businesses and citizens. IIs can create value by sharing and integrating data of multiple ac-tors. This can be the basis for value added services and especially collaborations of public and private partners can make IIs thrive. Easier access to integrated services and products (jointly) offered by government and businesses may stimulate transparency and innovations. IIs are under development in many do-mains, including for open data and international trade. However, there are nota-ble differences in the design, characteristics and implementation of the IIs. The objective of this paper is to compare two diverse IIs in order to obtain a better understanding of common and differing elements in the IIs and their impact. Among the differences are the roles of government, businesses and users, in driving, developing and exploitation of the IIs.Multi Actor SystemsTechnology, Policy and Managemen

Author Correction: Human Sexual Cycles are Driven by Culture and Match Collective Moods
No full textThis deposit is composed simultaneously by the original published article and also by the "correction" for the published article (erratum).This deposit is composed by the main article plus the supplementary materials of the publication.The link for the original article: https://www.nature.com/articles/s41598-017-18262-5A correction to this article has been published and is linked from the HTML and PDF versions of this paper. The error has not been fixed in the paper.Human reproduction does not happen uniformly throughout the year and what drives human sexual cycles is a long-standing question. The literature is mixed with respect to whether biological or cultural factors best explain these cycles. The biological hypothesis proposes that human reproductive cycles are an adaptation to the seasonal (hemisphere-dependent) cycles, while the cultural hypothesis proposes that conception dates vary mostly due to cultural factors, such as holidays. However, for many countries, common records used to investigate these hypotheses are incomplete or unavailable, biasing existing analysis towards Northern Hemisphere Christian countries. Here we show that interest in sex peaks sharply online during major cultural and religious celebrations, regardless of hemisphere location. This online interest, when shifted by nine months, corresponds to documented human births, even after adjusting for numerous factors such as language and amount of free time due to holidays. We further show that mood, measured independently on Twitter, contains distinct collective emotions associated with those cultural celebrations. Our results provide converging evidence that the cyclic sexual and reproductive behavior of human populations is mostly driven by culture and that this interest in sex is associated with specific emotions, characteristic of major cultural and religious celebrations.National Institutes of Health grant: (01LM011945-01); Fundação para a Ciência e a Tecnologia grant: (PTDC IVC ESCT 5337 2012); Welcome DFRH WIIA 60 2011; Marie Curie Actions; Defense Advanced Research Projects Agency (DARPA) - NGS2 program grant: (#D17AC00005); Economic Development Agency grant: (ED17HDQ3120040); NSF Award grant: (IIS-0811994).info:eu-repo/semantics/publishedVersio
URI Disambiguation in the Context of Linked Data
No full textThe Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates two popular resources, DBLP and DBpedia, and discusses whether the issues regarding identity management and co-reference resolution have been suitably addressed. We find that a large percentage of authors in DBLP have been conflated, and that disambiguation pages have been incorrectly linked using owl:sameAs within DBpedia. Systems for dealing with these issues are presented, and directions are given for future research
