Characteristics of Se'i (Rotenesse Smoked Meat) Treated with Coconut Shell Liquid Smoked and Citrus Aurantifolia Extract
The objective of this study was to investigate the effect of Citrus aurantifolia extract (CAE), coconut shell liquid smoke (CSLS) and the combination of CAE and CSLS (CACS) on se'i characteristics. A completely randomized design was assigned in this experiment. Treatments used were: se'i treated with 5% (v/v) CAE, CSLS 5% (v/v), (CAE : CSL 1:1) )/ (CACS) and untreated se'i as a control (C). Parameters measured were: aroma, color, taste, pH, residual nitrite, total bacterial count, Coliform, Staphylococcus aureus, Escherichia coli, and Salmonella. The data of aroma, color, and taste were analyzed by using Kruskal-Wallis test followed by Mann-Whitney test. The pH, residual nitrite, and bacterial data were analyzed with analysis of variance (ANOVA) followed by least significant differences test. Results showed that CAE caused the highest score at both aroma and taste (P<0.05). CSLS caused the lowest residual nitrite (27 ppm) (P<0.05). Application of CAE and CACS could reduce total bacteria (P<0.05) at least 1 log. Color, pH, and Coliform number were not significantly different. S. aureus, E. coli, and Salmonella were negative in all se'i samples. CAE gives the best organoleptics and bacteriological characteristics while CSLS is more effective in reducing nitrite
Control primitives for robot systems
A methodology is developed for describing of hierarchical control of robot systems in a manner which is faithful to the underlying mechanics, structured enough to be used as an interpreted language, and sufficiently flexible to encompass a wide variety of systems. A consistent set of primitive operations which form the core of a robot system description and control language is presented. This language, motivated by the hierarchical organization of neuromuscular systems, is capable of describing a large class of robot systems under a variety of single-level and distributed control schemes

Impact of Auto-evaluation Tests as Part of the Continuous Evaluation in Programming Courses
The continuous evaluation allows for the assessment of the
progressive assimilation of concepts and the competences that must be
achieved in a course. There are several ways to implement such contin uous evaluation system. We propose auto-evaluation tests as a valuable
tool for the student to judge his level of knowledge. Furthermore, these
tests are also used as a small part of the continuous evaluation process,
encouraging students to learn the concepts seen in the course, as they
have the feeling that the time dedicated to this study will have an assured
reward, binge able to answer correctly the questions in the continuous
evaluation exams. New technologies are a great aid to improve the auto evaluation experience both for the students and the teachers. In this
research work we have compared the results obtained in courses where
auto-evaluation tests were provided against courses where they were not
provided, showing how the tests improve a set of quality metrics in the
results of the courseMinisterio de Economía y Competitividad TIN2017-88209-C2-

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
of special education instead of being focused on the design and implementation of interventions for students with
specific problems. The apparent dissatisfaction of school psychologists with this trend and the difficulties dealing with
categorical diagnostic models within the school context have stimulated a movement toward the implementation of
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

Levumi: A Web-Based Curriculum-Based Measruement to Monitor Learning Progress in Inclusive Classrooms
Our paper introduces and assesses the Levumi platform’s web-based assessment of reading fluency. One challenges of inclusive education is meeting the needs of the learners with special education needs (SEN). Children with SEN and other risk factors face an increased risk of failing in schools and manifesting academic and social problems over the time. Web-based curriculum-based measurement (CBM) can provide an effective tool to track progress of learners and limit such risks. In particular, it can ease the challenges of test administration in inclusive classrooms through automation and providing multiple difficulty levels without the need of different paper-forms. Furthermore, Levumi can help educators track children and thus provide support for learners. Levumi takes advantage of the strengths of web-based CBM to assess reading fluency in primary school students. We confirmed the reading fluency test’s test-retest reliability (n = 334), its ability to measure learning over time in individual learners with SEN (n = 8, across 14 MPs), and its applicability to learners with SEN (n = 300, including n = 46 with SEN). We evaluate Levumi’s overall usefulness in assessing different types of learners, and discuss its contributions to CBM research
Detecting Earth-like Biosignatures on Rocky Exoplanets around Nearby Stars with Ground-based Extremely Large Telescopes
As we begin to discover rocky planets in the habitable zone of nearby stars with missions like TESS and CHEOPS, we will need quick advancements on instrumentation and observational techniques that will enable us to answer key science questions, such as What are the atmospheric characteristics of habitable zone rocky planets? How common are Earth-like biosignatures in rocky
planets?} How similar or dissimilar are those planets to Earth? Over the next decade we expect to have discovered several Earth-analog candidates, but we will not have the tools to study the atmospheres of all of them in detail. Ground-based ELTs can identify biosignatures in the spectra of these candidate exo-Earths and understand how the planets' atmospheres compare to the Earth at different epochs. Transit spectroscopy, high-resolution spectroscopy, and reflected-light direct imaging on ELTs can identify multiple biosignatures for habitable zone, rocky planets around M stars at optical to near-infrared wavelengths. Thermal infrared direct imaging can detect habitable zone, rocky planets around AFGK stars, identifying ozone and motivating reflected-light
follow-up observations with NASA missions like HabEx/LUVOIR. Therefore, we recommend that the Astro2020 Decadal Survey Committee support: (1) the search for Earth-like biosignatures on rocky planets around nearby stars as a key science case; (2) the construction over the next decade of ground-based Extremely Large Telecopes (ELTs), which will provide the large aperture and
spatial resolution necessary to start revealing the atmospheres of
Earth-analogues around nearby stars; (3) the development of instrumentation that optimizes the detection of biosignatures; and (4) the generation of accurate line lists for potential biosignature gases, which are needed as model templates to detect those molecules
