Enhancing Voter Education Knowledge of Adolescents Through Social Interaction Instructional Models

The study determined the effects of group investigation and jurisprudential inquiry of social interaction instructional models on adolescents’ knowledge of voter education related contents in senior secondary school Government curriculum. The ultimate aim was to curb voter apathy among young citizens. The design was Quasi-experimental non-equivalent pre-test, post-test control group design. The sample for the study consisted of 165 SS II students drawn from public secondary schools in Nsukka Local Government Area of Enugu state Nigeria. Using a multi-stage sampling technique, the intact classes from the schools were assigned to the two experimental groups. Data collected using Multiple Choice Government Achievement Test (MCGAT) were analyzed employing mean and standard deviation for the research questions and ANCOVA for testing the hypothesis at P < 0.05 level of significance. The findings showed that group investigation and jurisprudential inquiry models enhanced students’ acquisition of knowledge in voter education related contents; although group investigation seemed more efficacious. There was also a statistical difference in the mean achievement scores of students with group investigation performing significantly better. These findings were exhaustively discussed with the far-reaching recommendations on how to improve voter education knowledge and potentials of young ones as future adult citizens.
The Dirichlet problem for the uniformly elliptic equation in generalized weighted Morrey spaces

In this paper, we obtain generalized weighted Sobolev-Morrey estimates with weights from the Muckenhoupt class Ap by establishing boundedness of several important operators in harmonic analysis such as Hardy-Littlewood operators and Calderon-Zygmund singular integral operators in generalized weighted Morrey spaces. As a consequence, a priori estimates for the weak solutions Dirichlet boundary problem uniformly elliptic equations of higher order in generalized weighted Sobolev-Morrey spaces in a smooth bounded domain Ω ⊂ ℝn are obtained.
Evaluating the Power Output of the Smith-Root GPP 5.0 Electrofisher to Promote Electrofishing Fleet Standardization

Abstract The Smith-Root (S-R) series of GPP (gas-powered pulsator) electrofishers are widely used in boat-mounted electrofishing systems. Sampling in waters having different conductivities requires adjustment of the electrofisher controls to maintain consistent output power. However, the current meter supplied on GPP electrofishers provides an average rather than a peak measurement, and because no voltmeter is included, determining peak power output is not possible. As part of an overall effort to promote standardization of electrofishing operations, we used static electrical loads to measure the output characteristics of the commonly used S-R GPP 5.0 electrofishers under simulated electrofishing conditions. The range of resistance values to be simulated with static loads was extrapolated from in-water measurements of five electrode configurations consisting of paired, half-submerged, spherical anodes in combination with a 5.5-m-long flat-bottom aluminum-hull boat serving as the cathode. We measured the p.
Fall stopover strategies of three species of thrush (Catharus) in northern South America

ABSTRACT Northern South America is a geographic bottleneck that may be limiting the survival of Nearctic–Neotropic migrants. However, very little is known about the migration ecology of transcontinental migrants wintering in South America. We studied the fall migratory strategies of three species of thrush (Catharus ustulatus, C. fuscescens, and C. minimus) at 2 major migrant gateways into South America: the Darién and the Sierra Nevada de Santa Marta (SNSM) of northern Colombia. Assuming that migration route shapes the stopover strategy of birds and that our sites receive birds from 2 different routes, we predicted that (1) migrants traveling over land through Central America (Darién) would make short and frequent stopovers followed by short flights and (2) migrants crossing the Caribbean (SNSM) would make few and long stopovers to acquire fuel for longer flights. To test these predictions, we estimated condition on arrival, stopover duration, fuel deposition rates, and potential flight ranges after stopover, using 3 yr of capture–recapture data. Each species adopted a different stopover strategy, with Swainson's Thrush arriving in South America through the Darién, making the shortest stopovers and achieving the shortest flight ranges (800 km); Gray-cheeked Thrush arriving primarily through the Darién, making short stopovers but achieving longer flight ranges (1,200 km); and Veery arriving in both the Darién and the SNSM, making the longest stopovers and achieving the longest flight ranges (1,900 km). Our results suggest that stopover strategies are shaped by both migratory route (over land vs. over water) and distance to final destination in South America. Unraveling the breeding origins and wintering destinations of individuals passing through northern Colombia would greatly improve our understanding of hemispheric migration systems and will be critical if we are to protect the most important stopover sites and habitats.
Density‐Dependent Fecundity by Habitat Heterogeneity in an Increasing Population of Spanish Imperial Eagles

We report on a 32-yr study of a population of Spanish Imperial Eagles, Aquila adalberti, which increased during the first 16 yr of study but remained stable during the last 16 yr. We analyzed changes in the mean and variance of fecundity in relation to population density to test predictions of two hypotheses of density-dependent fecundity. According to the "interference" hypothesis, as density increases, frequency of agonistic encounters increases, resulting in a relatively uniform decrease in habitat quality. Conse- quently, mean fecundity decreases, and no relationship is expected between density and variance in fecundity. For the "habitat heterogeneity" hypothesis, however, as density increases, a greater proportion of individuals are forced to occupy lower quality habitats. Thus, mean fecundity decreases and fecundity variance must increase. Additionally, for this hypothesis, fecundities in good sites are expected to be equal in both low- and high- density situations. An inverse relationship between fecundity and population size was found in this eagle population. Annual variance in productivity showed significant increases over the study period. This trend was inversely related to mean productivity. Variance in pro- ductivity was related to the year of pair establishment, being higher in recently occupied territories. Mean and variance of the longer term territories remained constant during the study period. These results are in accordance with the habitat heterogeneity hypothesis.
Determinação da concentração de diferentes sistemas de solventes na solubilização de proteínas de análogo de carne

The use of specific solvents for protein extraction determines the type of chemical reaction, which occurs between the protein components, mainly when the protein was submitted to thermal treatment, such as thermoplastic extrusion, a technology with high versatility, low cost and high throughput and without effluent generation. However, it is necessary to use adequate solvents concentration in order to maximize the protein extraction. The aim of this research was to evaluate the protein solubilization of meat analogue based on isolate soy protein and vital gluten submitted to thermoplastic extrusion process at low moisture content (23%) and high moisture content (60%). The solvents used were: phosphate buffer (pH 7.5) at 10, 20, 40, 60, 80 and 100mM, sodium dodecyl sulphate at 1, 2, 3, 4 and 5%, β-mercaptoethanol at 1, 2, 3 and 4%, Triton X-100 at 1, 2, 3 and 4% and urea at 6, 7, 8, 9 and 10M. All the chemical reagents were dissolved or solubilized in phosphate buffer 40mM (pH 7.5). The results showed that the highest protein extraction were obtained when phosphate buffer 40mM, sodium dodecil sulphate 2%, β-mercaptoethanol 2%, Triton X-100 3% and urea 7M were used

Keys are given to males and females of 12 species of Cloeon known from Eastern Africa, including descriptions of C. amaniensis sp.n. and C. tanzaniae sp.n. The new genus Rhithrocloeon presumed to be a torrential form, is defined in terms of the character of the male forceps and the proportions of hind tarsal segments. Two species, permirum Kopelke and insuetum Kopelke from Eastern Zaire, formerly included in Cloeon are transferred to Rhithrocloeon and one new species, R. indicator sp.n. is described from Tanzania.
Habitat preferences and conservation of Vertigo geyeri (Gastropoda: Pulmonata) in Slovakia and Poland

The tiny land snail Vertigo geyeri Lindholm, 1925 is a rare relict from the Late Glacial, inhabiting treeless spring fens. The main aims of this study were (1) to summarize present knowledge on distribution of V. geyeri in Slovakia and in Poland; (2) to analyse its ecology and habitat preferences; and (3) to suggest suitable conservation and management measures for this EUHSD Annex II species. In the course of field research on 122 fens in Slovakia and Poland, carried out between 2001 and 2011, we documented 33 Slovak and 24 Polish sites where this species occurred. Based on analysis of these populations, we identified a strong preference for permanently wet, but not extremely waterlogged, open fen sites with low-productivity nutrient-limited vegetation. The species displayed a unimodal response to calcium concentration in the groundwater, avoiding both calcium-poor Sphagnum-dominated fens and extremely mineral-rich and salt travertine fens. All sites in which V. geyeri occurs should be protected to prevent any hydrological changes resulting in successional shifts towards more productive and shrubby vegetation. Human-induced eutrophication should be also controlled to ensure the long-term maintenance of viable populations of the species. The locations of all Slovak and Polish fen sites in which V. geyeri has been recorded are provided to enable or maintain protection of the species at these sites.
Steady Output and Fast Tracking MPPT (SOFT-MPPT) for P&O and InC Algorithms

Among the various MPPT algorithms developed until date, Perturb and Observe (P&O) and Incremental conductance (InC) algorithms are most widely used, mainly due to their simplicity and ease of implementation. However, both algorithms suffer from the drawbacks of continuous steady state oscillations, and inefficient tracking in case of rapid changes in irradiation. In this article, a SOFT-MPPT algorithm has been proposed which, in a simple way, aims to improve both the steady state as well as the tracking performance of both P&O and InC algorithms. An adaptive step size is used to track the MPP, which provides a faster tracking performance. The proposed algorithm identifies the attainment of the steady state and then stops the artificial perturbations. This stops the oscillations around the MPP and provides a steady power output from the PV panel at the MPP value. The SOFT-MPPT algorithm is also able to detect any change in operating conditions while operating in the steady state, and that too without using any additional sensors. Accordingly, it restarts the tracking process in order to track the new MPP. The detailed theoretical discussions of the SOFT-MPPT algorithm, is followed by the simulation and experimental results to validate the proposed performance improvements.
Classes de comprimento e proporção sexual em Diplodon expansus (Mollusca, Bivalvia, Hyriidae) no rio Piraquara, Paraná, Brasil

This study aimed to analyze the distribution of size classes and sex ratio to broaden the knowledge on the reproductive behavior of Diplodon expansus (Kuster, 1856) and the biodiversity of the water bodies of the Area de Protecao Ambiental Piraquara, Parana, Brazil. The study area is a section of the Piraquara river, characterized by lotic water and relatively well preserved riparian vegetation. Four samplings were carried out from March 2006 to December 2006. In the Piraquara river, D. expansus occurs in sections of the river with sandy and slimy substrate. The length of specimens ranged from 17 mm to 65 mm, and the highest frequencies of length classes were found for intermediate sizes. Histological analysis of gonads revealed a 1:1 sex ratio. No hermaphrodite specimens were found, characterizing a dioecious population. Qualitative and quantitative analysis showed a continuous gametogenesis, with peaks of larval release in the summer.
Estimating occupancy and abundance of stream amphibians using environmental DNA from filtered water samples

Environmental DNA (eDNA) methods for detecting aquatic species are advancing rapidly, but with little evaluation of field protocols or precision of resulting estimates. We compared sampling results from traditional field methods with eDNA methods for two amphibians in 13 streams in central Idaho, USA. We also evaluated three water collection protocols and the influence of sampling location, time of day, and distance from animals on eDNA concentration in the water. We found no difference in detection or amount of eDNA among water collection protocols. eDNA methods had slightly higher detection rates than traditional field methods, particularly when species occurred at low densities. eDNA concentration was positively related to field-measured density, biomass, and proportion of transects occupied. Precision of eDNA-based abundance estimates increased with the amount of eDNA in the water and the number of replicate subsamples collected. eDNA concentration did not vary significantly with sample location in th.
Increasing trend in rapid intensification magnitude of tropical cyclones over the western North Pacific

Rapid intensification (RI) refers to a significant increase in tropical cyclone (TC) intensity over a short period of time. A TC can also undergo multiple RI events during its lifetime, and these RI events pose a significant challenge for operational forecasting. The long-term tendency in RI magnitude of TCs over the western North Pacific is investigated in this study. During 1979–2018, a significant increasing trend is found in RI magnitude, which primarily results from the significant increasing number of strong RI events, defined as 24 h intensity increases of at least 50 kt. Furthermore, there are significantly more (slightly fewer) strong RI occurrences west (east) of 155°E in 1999–2018 than in 1979–1998. Significant increases in strong RI occurrences are located over the region bounded by 10°∼20°N, 120°∼150°E. These changes are likely induced by the warming ocean but appear uncorrelated with changes in the atmospheric environment. By contrast, there are slight decreases in strong RI occurrences over the region bounded by 12.5°∼22.5°N, 155°∼170°E, likely due to the offset between RI-favorable influences of the warming ocean and RI-unfavorable influences of increasing vertical wind shear (VWS).
Predation and avoidance of tough leaves by aquatic larvae of the moth Parapoynx rugosalis (Lepidoptera: Pyralidae)

Abstract. 1 Aquatic larvae of the pyralid moth Parapoynx rugosalis Möschler repeatedly construct protective cases by cutting portions (discs) from leaves of the waterlily Nymphaea ampla and sandwich themselves between the disc and the underside of the host leaf. Construction of a new case requires leaving the old case, thus increasing exposure to predators and parasites. 2 In an experiment, larvae with protective cases experienced no mortality due to predation by fish, whereas larvae without cases experienced substantial predation. 3 In a series of choice tests, larvae preferentially selected young, tender leaves over old, tough leaves for construction of cases, and larvae spent significantly less time completing their shelters when cutting discs from young, tender leaves. 4 A partial explanation of why larvae select young, tender leaves for construction of their protective shelters may be that exposure time to predators during construction is minimized. 5 The same mechanism linking preferences for tender leaves to reduced exposure to predators during construction may also apply to other insect herbivores exhibiting leaf‐rolling or case‐building behaviour.
The influence of environmental factors on abundance and prevalence of a commensal ostracod hosted by an invasive crayfish: are ‘parasite rules’ relevant to non‐parasitic symbionts?

Summary Symbiosis represents a widespread and successful lifestyle, but research on symbiotic associations has been mainly focused on parasites. Three general patterns in parasite ecology have been proposed: (i) aggregation, (ii) positive and tight correlation between mean symbiont abundance and its variance and (iii) positive correlation between abundance and prevalence of symbionts. The factors affecting abundance and prevalence within symbiont species can be grouped into host features and environmental conditions. According to research in parasite ecology, environmental conditions seem to play a minor role. We investigated whether the three most recognised parasite patterns were also evident in a non-parasitic freshwater ectosymbiont and analysed the effects of host features (sex, body size, density and ecdysis) and environmental conditions (climate and water chemistry) on abundance and prevalence of the symbiont. Our species model was an exotic ectocommensal ostracod, Ankylocythere sinuosa, inhabiting the invasive crayfish Procambarus clarkii in Europe. We sampled 373 crayfish from 26 Spanish localities. We modelled both abundance per occupied host (i.e. intensity) and prevalence using zero-altered models and a backward model selection of host and environmental variables, and assessed model performance through graphical analyses of Pearson residuals and the relationship between observed and fitted values of the finally selected model. We observed all three parasite patterns in A. sinuosa. Abundance of A. sinuosa was most strongly related to conductivity (negative effect), followed by host density (positive) and ecdysis (negative), with moderate relationships to variables related to water chemistry (NH4+ concentration, alkalinity/(Cl− + SO42−) and Cl−/SO42− ratios). Prevalence was related mainly to crayfish density (positive effect) and also to climatic conditions (maximum temperature of warmest month, annual precipitation and precipitation seasonality). Our results suggest that some ‘parasite rules’ may actually be general ‘symbiont rules’. Moreover, our symbiont model was markedly affected by climatic conditions at a regional scale acting on prevalence, and water chemistry at a local level acting on symbiont abundance. This supports the hypothesis of a prominent role of environmental conditions influencing population parameters of non-parasitic freshwater ectosymbionts. Physiological tolerances to highly unstable environmental factors, together with dependence on highly variable external food sources, probably underlie the high sensitivity to environmental conditions of this category of symbiont.
Temporal Upsampling of Point Cloud Sequences by Optimal Transport for Plant Growth Visualization

Plant growth visualization from a series of 3D scanner measurements is a challenging task. Time intervals between successive measurements are typically too large to allow a smooth animation of the growth process. Therefore, obtaining a smooth animation of the plant growth process requires a temporal upsampling of the point cloud sequence in order to obtain approximations of the intermediate states between successive measurements. Additionally, there are suddenly arising structural changes due to the occurrence of new plant parts such as new branches or leaves. We present a novel method that addresses these challenges via semantic segmentation and the generation of a segment hierarchy per scan, the matching of the hierarchical representations of successive scans and the segment‐wise computation of optimal transport. The transport problems' solutions yield the information required for a realistic temporal upsampling, which is generated in real time. Thereby, our method does not require shape templates, good correspondences or huge databases of examples. Newly grown and decayed parts of the plant are detected as unmatched segments and are handled by identifying corresponding bifurcation points and introducing virtual segments in the previous, respectively successive time step. Our method allows the generation of realistic upsampled growth animations with moderate computational effort.
