Analisis Kelayakan dan Kepraktisan Modul Praktikum Berbasis Literasi Sains untuk Pembelajaran IPA

Practicum modules are needed during the practical learning process activities that can be used by teachers and students. Science literacy must be mastered by students, because it is related to the environment. Science literacy is assessed from three aspects namely content, process and context. The purpose of this study was to determine the feasibility test and practical test of practicum modules based on science literacy for science learning in SMP Negeri 1 Langsa. This type of research is research and development which is modified into three stages of research implementation with the module trial stage developed in the form of research and information gathering, module design phase and module development stage with documentary study data collection techniques, questionnaires, and experiments. The scores obtained will be processed using descriptive analysis by conducting a feasibility test by material and media experts consisting of biology education lecturers while the practicality test uses a questionnaire distributed to students of class VIII at SMP Negeri 1 Langsa on Natural Sciences subjects. The results showed that the IPA practicum product modules analyzed consisted of three categories: the percentage value of the highly valid aspects with a value of 78% on the module quality element, while the practicality test consisted of three aspects namely the content, process and context aspects of the results of the three aspects. The percentage value of 82.8% of the aspects of positive student response content that practicum modules are used is very practical. Based on the values obtained that the IPA practicum module is feasible and practically used as a practical guide.
Response to Comment on “A Dynamic Network Model of mTOR Signaling Reveals TSC-Independent mTORC2 Regulation”: Building a Model of the mTOR Signaling Network with a Potentially Faulty Tool

Dalle Pezze et al. respond to criticisms regarding the specificity of phosphorylation of Ser2481 of mTOR as a specific readout of mTORC2 activity. We modeled the mammalian or mechanistic target of rapamycin (mTOR) network and proposed a previously unknown mode of activation of the mTOR-containing complex mTORC2 through a phosphoinositide 3-kinase–dependent, and tuberous sclerosis complex–independent mechanism. Manning questions the validity of using the phosphorylation of Ser2481 of mTOR as a specific readout of mTORC2 activity and suggests an in vitro mTORC2 kinase assay as a more appropriate method to parameterize a dynamic mTOR model. We maintain that our computational-experimental approach in combination with careful selection of the readout and cell system is appropriate for studying mTORC2 regulation by insulin.
Seasonality of insect abundance in an Australian upland tropical rainforest

Monthly light and Malaise trap catches, taken over 31 months, were used to examine seasonal and annual changes in the abundance of predominant orders of upland tropical rainforest insects. Insect numbers and biomass increased during the late dry season, reached a peak during the wetter months, and declined during the early dry period. Fluctuations in insect abundance appeared to relate to (1) climatic factors such as length and severity of the dry season, or amount and period of rainfall; and (2) food availability such as an increase in the production of new leaves, or flowering and fruiting periodicity.
Increase in Total Elongation Caused by Pure Shear Deformation in Ultra-Fine-Grained Cu Processed by Equal-Channel Angular Pressing

Ultra-fine-grained (UFG) Cu shows little total elongation in tensile tests because simple shear deformation is concentrated in narrow regions during the initial stage of plastic deformation. Here, we attempted to improve the total elongation of UFG Cu obtained by equal-channel angular pressing. By making shallow dents on the side surfaces of the plate-like specimens, this induced pure shear deformation and increased their total elongation. During the tensile tests, we observed the overall and local deformation of the dented and undented UFG Cu specimens. Using three-dimensional digital image correlation, we found that the dented specimens showed suppression of thickness reduction and delay in fracture by enhancement of pure shear deformation. However, the dented and undented specimens had the same ultimate tensile strength. These results provide us a new concept to increase total elongation of UFG materials.
On the Prosody of Contrastive Topics in German Interviews

We investigate the prosodic realization of contrastive topics vs. non-contrastive, sentence-initial background expressions on a richly annotated corpus of German spoken interviews. The annotation of contrastive topics and other information-structural categories uses a recent discourse-analytic framework based on the concept of Questions under Discussion. We report that pitch accents on contrastive topics exhibit a signiﬁcantly wider pitch range but not a later peak than those on background elements.
Assessing the Intonation Style of Speakers with Autism Spectrum Disorder

Speakers with Autism Spectrum Disorder (ASD) have been claimed, and are generally assumed, to produce atypical intonation. Previous research, however, is very limited and findings are contradictory, with claims ranging from “robotic” to “singsongy” intonation styles in ASD. We employ a novel method to assess intonation styles in a large corpus of semi-spontaneous speech by German adults with ASD and matched controls. We show that the ASD group has a more melodic or singsongy intonation style as a whole, but that this effect is subject to a high degree of individual variation and that the difference between groups is greater for male than for female speakers. We compare the method of analysis proposed here with the more traditional measures of pitch range and mean f0, showing that the novel approach is able to capture the difference between intonation styles more clearly.
Thoracic morphology of adults of Derodontidae and Nosodendridae and its phylogenetic implications (Coleoptera)

Abstract External and internal structures of the thorax of six adult representatives of the families Derodontidae and Nosodendridae were examined. A detailed description of the skeleton and musculature is presented for Derodontus maculatus and Nosodendron sp. Phylogenetically relevant characters are discussed and analysed cladistically. A basal origin of Derodontidae within Polyphaga and a sister‐group relationship between this suborder and the remaining Coleoptera are not supported. Muscular and skeletal features of Derodontidae are largely consistent with the typical polyphagan pattern and the group is characterized by many specialized features. Previous references to the family as ‘primitive’ are unjustified. The absence of a firm connection between the meso‐ and metaventrite is a secondary feature, as seen in Scirtoidea and some members of Leiodidae. The contact of the metanepisternum with the mesocoxal cavity is probably also an autapomorphic condition. Two derived muscular features are shared by Derodontidae and Nosodendridae, and several muscle losses are shared by these two families and Scirtoidea and Dascillidae. The monophyly of Derodontidae and a sister‐group relationship between Peltastica and the remaining genera are confirmed. Laricobius and Nothoderodontus are probably sister groups. Nosodendron is characterized by several autapomorphic features. Whether the flight musculature is reduced in all members of Nosodendridae is unclear.
Comparative analysis of the access to health-care services and breast cancer therapy in 10 Eastern European countries

Aim: The aim of this study is to compare the differences in breast cancer therapy, health-care service practices, and their availability in ten European countries—Albania, Bosnia and Herzegovina, Bulgaria, Kosovo, Montenegro, Republic of North Macedonia, Croatia, Romania, Slovenia, and Republic of Serbia. Methods: An inquire survey was conducted among oncologists in the participating countries. The questionnaire was of qualitative character and focused on several key areas as screening practices, diagnosing, treatment, and health-care procedures utilization. The results were processed through comparative and percentage analysis. Results: All of the observed countries have national registries for breast cancer, but only in five, a mechanism of controlled action of early detection is implemented. Ninety percent of the countries have implemented in the national guidelines the European Society of Medical Oncology recommendations, while National Comprehensive Cancer Network is considered in only 50%. In all countries, digital mammography is a universal diagnostic method. Pathohistological analysis, including HER2 receptor expression and determination of the level of progesterone and estrogen receptors, is routinely performed in all countries prior to therapy. Some differences are observed in terms of FISH/CISH methods, determination of Ki-67 volume, and prognostic molecular assays. Trastuzumab is used as neo-adjuvant therapy in HER2-positive disease in all countries, while in Bosnia and Herzegovina and Croatia, only pertuzumab is used. Psychological support is integrated into the professional guidelines for treatment and monitoring in Bosnia and Herzegovina, Bulgaria, and Serbia. Conclusions: The international guidelines should be followed strictly, and some improvements in the health policies should be made in order to decrease the differences and inequalities in the availability of the breast cancer (BC) health services in the Central and Eastern European countries.
Genus Pimelea (Thymelaeaceae) in New Zealand 2. The endemic Pimelea prostrata and Pimelea urvilliana species complexes

Abstract The taxonomy of the glabrous‐leaved plants ascribed to Pimelea prostrata and P. urvilliana (here each regarded as members of a species complex) is examined. The entities that were originally classed under the names prostrata and urvilliana are identified and the species typified and described. The Pimelea prostrata complex consists of three species: P. prostrata (with four additional new subspecies); and the new species Pimelea orthia (two subspecies) and Pimelea xenica, each from scattered locations in the northern half of the North Island. Pimelea prostrata subsp. prostrata occurs in scattered places in the southern half of the North Island and very widely in the South Island. The other infraspecific units in P. prostrata, each distributed regionally, are subspecies seismica, vulcanica, thermalis, andventosa. Pimelea orthia subsp. orthia is an inland to near coastal plant whereas subsp. protea lives only on coastal dunes. The Pimelea urvilliana complex consists of six species: P. urvilliana subspecies urvilliana (now only in the Auckland region), with one new subspecies, nesica (on islands east of Auckland and Coromandel); the new species Pimelea carnosa (coastal sites in North and South Islands); Pimelea sporadica (four widely spread sites in the northern half of the North Island); Pimelea eremitica (from a single North Auckland location); and two species described in an earlier paper, Pimelea actea (from the Manawatu‐Wanganui coast) and Pimelea telura (Three Kings Islands) Some of the subspecies of P. prostrata are relatively common as is P. urvilliana subsp. nesica and, locally, P. carnosa. None of the other taxa covered here is abundant. Pimelea urvilliana subsp. urvilliana is particularly scarce and may be extinct on the New Zealand mainland. Live populations and herbarium specimens include individuals with mixed characters indicating that some taxa cross freely with one another if the opportunity arises. Hybridisation occurs between some members of the P. prostrata complex. Hybrids are also found between some members of the P. urvilliana complex. Also, certain members of each of these two groups hybridise with one another. Overall, the crossing has generated a high degree of variability in some field populations ("hybrid swarms” and far‐reaching introgression) especially among coastal plants. The complex character assortments in some of these populations are recorded, using scatter diagrams and pictographs. A key for identification of all glabrous‐leaved Pimelea taxa in New Zealand includes those in the Pimelea gnidia group of species as well as the P. prostrata and P. urvilliana species complexes. Hybrids are not covered in the key, but information to assist in their identification appears in the text.
Macroinvertebrate assemblage response to urbanization in three mid-continent USA great rivers

We sampled macroinvertebrates in the benthos and on the surface of woody snags in three mid-continent USA great rivers, the Upper Mississippi River, the Lower Missouri River, and the Ohio River, all of which flow through several large urban areas. We defined urban and non-urban zones of each river based on mean percent impervious surface extracted from recent land cover data. We estimated that 28-36 % of the rivers, by length, was urbanized. Based on multivariate ordination, the overall structure of the great river assemblages was not different between urban and non-urban zones for either the benthos or snags in any river. Most taxa (82 %) did not exhibit a significant positive or negative effect of urbanization in either river. Many of the taxa that were responsive to zone type were relatively rare (river- and habitat-specific relative abundance < 5 %). For responsive taxa, the effects of urbanization were generally weaker on the Upper Mississippi and Ohio Rivers than on the Lower Missouri River and weaker for snag-surface assemblages than for the littoral benthos. Among the taxa that were more abundant in urban sections were several insect taxa generally considered intolerant of pollution. We speculate that urbanization, possibly due to nutrient enrichment and resulting increased food resources (algae, seston), may improve conditions for these taxa. There appeared to be a threshold in mean percent impervious surface for a great river subcatchment near 5 % above which urban-intolerant taxa were always rare and urban tolerant taxa were often abundant.
Mobile and printed dichotomous keys in constructivist learning of biology in primary school

ABSTRACT Background: Exploring using constructivist learning has become a focus of educational research in recent years. However, no available research has been found which examines the contribution of constructivist learning through the implementation of handheld computers and tablets (in the literature, a constructivist mobile learning environment refers to constructivist learning with the implementation of mobile devices) to student knowledge across cognitive levels, while their opinion on that contribution in biological education in primary schools is as yet unreported. Purpose: The main aim of this research is to examine the contribution of the Dichotomous Mobile Key (DMK) and the Dichotomous Printed Key (DPK), implemented in the classroom through constructivist learning, to student achievement and the sustainability of the primary school students' biological knowledge about the Systematic and classification of plants at all cognitive levels. The research also analyses students' opinions about the applied dichotomous keys in the constructivist learning process and the correlation between student knowledge and their opinion about the application of the DMK or the DPK. Design and methods: This research uses a quasi-experimental design and involved 140 eight-grade students from Montenegro assigned to two experimental groups, learning through: 1) the DPK (Group C) and 2) the DMK (Group E). Results and conclusions: The results indicate that studying using a DMK is more suitable than a DPK for learning botany in primary schools when implementing a constructivist approach. This is because the DMK is better suited to enhancing some elements of certain constructivist approaches, notably eliciting students’ prior knowledge; facilitating exploratory learning; creating cognitive dissonance; and receiving continuous feedback during the entire learning process. The contribution of the DMK is greater than that of the DPK to students’ knowledge and opinions to the contribution of the applied dichotomous key to their knowledge and greater desire to learn about plants.
Black spruce crown fuel weights in northern Ontario

Eighty black spruce (Piceamariana (Mill.) B.S.P.) trees from four pulpwood stands in north central Ontario were sampled to determine crown fuel weights. Crown fuel components, both living and dead, were separated into size classes precise enough for use in forest fire behavior research. Regression equations expressing various crown fuel components as a function of tree diameters at breast height (DBH) were derived, and the resulting.R2 values were between 0.75 and 0.84. Total crown biomass figures are presented herein for the four stands sampled. Approximately 80% of the total crown weight per hectare is made up of fuel particles ≤0.64 cm in diameter (including needle foliage). Live fuels make up approximately 74% of total crown weight per hectare.
Population dynamics and diversity of Bactocera species and Dichasmimorpha longicaudata, its parasitoid in correlation with abiotic factors

Fruit flies are destructive pests and caused heavy losses in agricultural products by reducing crop production. The reported study was planned to evaluate the relationship between population dynamic of fruit flies and its parasitoid in guava orchards in relation to prevailing ecological condition. For this purpose, baited pheromone traps containing methyl eugenol with contact action Insecticides were installed in guava orchards in Faisalabad district during 2016-18. Trapped fruit flies were collected after every fortnightly interval and brought in the laboratory for identification of species. The infested guava fruits were also collected from fruit trees during the fruiting season and kept under laboratory conditions to identify and record parasitoids species as well as emerging Fruit flies. Results revealed that B. zonata, B. correcta and B. dorsata prevail around the year. However population of B. dorsata was more than B. zonata followed by B. correcta. Peak infestation of fruit fly was has been observed in October 2016-17 while in 2018 highest population was recorded in September. However, low population of fruit flies species had been recorded when temperature dropped < 05 oC. Emergence from infested fruit predicts that 60% emergence was solely by the population of B. dorsata followed by B. zonata and B. correcta throughout the year. The highest number of D. longicaudata was recorded in July and August and also directly influenced by pupae emergence from the larvae. Highest and lowest temperature exerted more effect on population fluctuation of pest as well as its parasitoid as compared to other factors.
Еffect of insect infestation on the economic value of smoked fish sold in selected markets in Nigeria

In the present study a multistage sampling technique using semi-structured questionnaire was used to obtain information on socioeconomic characteristics of the respondents and on economic loss of smoked fish resulting from insect pest infestation. Smoked fishes were bought from 10 markets in Oyo state, South West of Nigeria and checked in the laboratory for the insect pests. Data were analyzed using descriptive statistics and Chi-square. Results indicated that insects at their larvae stage cause more economic loss to smoked fish than adult insects while Necrobia rufipes and Dermestes spp. are the insects found to infest the smoked fishes in this study. The insect infestation of the smoked fish leads to huge economic loss. Of all respondent groups the women dominate smoked fish business.
Feasibility and Applicability of Standardized and Regular Follow-up of Sickle Cell Patients in a Remote Area of a Developing Country

Background: Sickle cell disease (SCD) is the most common hemoglobinopathy in the Democratic Republic of Congo (DRC) and poses a public health problem. If, without clinical follow-up, more than 50% of children with SCD die before their 5th birthday. A regular medical follow-up is the first simple improvement that can be beneficial for SCD patients in a remote city of an African country. Method: A cohort of 143 children with SCD aged 10 years old (IQR [inter quartile range]: 6–15 years) (sex ratio male: female = 1.3) were clinically followed for 12 months without any specific intervention and then 12 months with a monthly medical visit, a biological follow-up and regular prophylaxis. A paired Student test and pairwise Wilcoxon test were used to compare study outcomes. Results: The median age of patients at the diagnosis of SCD was 2 years (IQR: 1–5). Anemia was noted in 100% of patients at inclusion, with severe and normocytic anemia in 80% of cases (n = 115). The implementation of standardized and regular follow-up has shown an increase in the annual mean hemoglobin level from the percentage of the low limit normal for the age from 54 to 77 % (p = 0.001), and a decrease of the lymphocytes count and spleen size (p < 0.001). The implementation of regular follow-up has also shown a significant decrease (p < 0.001) in the average annual number of hospitalizations and episodes with vaso-occlusive crises, blood transfusions, infections, and acute chest syndromes. Conclusions: This study showed that the regular follow-up of children with SCD and the application of SCD management recommendations are possible and applicable in the context of a remote city in a developing country. Simple and accessible measures included in conventional recommendations can reduce the morbimortality of these patients in remote areas if applied rigorously with regular follow-up.
The effects of tonal experience on the categorization of Cantonese lexical tones into Japanese native pitch accent categories

This study examined the effects of prosodic experience in the first (L1) and second (L2) language on the perception of nonnative lexical tones. Japanese naïve listeners (Group JN) and Japanese learners of Mandarin (Group J1M2) were instructed to categorize the six Cantonese lexical tones into their native pitch accent categories. Results showed that both groups could only categorize two tones into their native pitch accent categories, and their categorization patterns were different: Group JN only assimilated two rising tones, T2 and T5, into the final-accented LH* while Group J1M2 assimilated high-rising T2 into LH* and low-falling T4 into initial-accented H*L. These preliminary results are only partly compatible with the assumptions of Perceptual Assimilation Model for Suprasegmentals (PAM-S) stating that non-native tonal categories will be assimilated to native prosodic categories, but provide more evidence that learning a more complicated system with lexical F0 variations at the phonetic level (i.e. Mandarin) does influence the perceptual assimilation of nonnative tones.
