Abstract Background Common Bushbuck (Tragelaphus scriptus) is one of the most widely distributed antelope species in African continent and use a wide variety of habitat types. A study on population status and feeding ecology of common bushbuck in Moledo Forest, West Gojjam, Ethiopia was carried out from September 2017 to August 2018 during wet and dry seasons. Data were collected using total count method and focal sampling technique. Then, the collected data were analyzed using descriptive statistics and compared with t-test for population status and percentage contribution of food items. Plant species consumed were compared with Chi-square test between seasons.Results The result indicated that the total numbers of bushbuck population were 18 and 28 during dry and wet seasons, respectively. There was a significant difference (t = 0.61, df = 4, p < 0.05) in bushbuck population during both seasons. Sex ratio of adult male to adult female was1.4:1. On the other hand, 20 plant species belonging to 11 families were recorded as food for study animal. Food items were significantly differed between seasons ({{\chi }}^{2}= 930.88, df = 1, p < 0.05). Their food items mainly constituted 50% shrub, 30% herb and 20% tree. Young leaves contributed to 40% of their diet followed by mature leaves 26%. On the other hand, flowers contributed the least (6%) for their diet. There was a significant variation ( {{\chi }}^{2} = 98, df = 10, p < 0.05) in parts of plant consumed by common bushbuck in the study area.Conclusion There are some threats associated with common bushbuck in the study area such as livestock grazing, habitat encroachment, fire wood collection, predation and hunting. Therefore, immediate attention needs to be paid to conserve the study animal in particular and other wildlife in general.

Girls between the ages of 9 and 10 begin to experience physical, physiological, and hormonal changes that may lead to internal stress. At this age, children are struggling for autonomy; on the other hand, they may experience emotional instability, and for these reasons, they may be vulnerable in many ways. This experimental study aimed to investigate the effect of resilience training on assertiveness in student girls aged 9–10. Data were collected before, immediately after, and 1 month after the intervention in the control ( n = 40) and intervention ( n = 37) groups. There was a significant difference between the assertiveness of the intervention immediately (26.80 ± 3.73) and 1 month after the intervention (27.05 ± 3.73), and assertiveness significantly increased in the intervention group ( p = .0001). Resilience training leads to improvements in assertiveness in student girls aged 9–10.

Integrating the properties of computer algebra systems and dynamic geometry environments, Geogebra became an effective and powerful tool for teaching and learning mathematics. One of the reasons that teachers use Geogebra in mathematics classrooms is to make students learn mathematics meaningfully and conceptually. From this perspective, the purpose of this study was to investigate whether instruction with Geogebra has effect on students’ achievements regarding their conceptual and procedural knowledge on the applications of derivative subject. This study adopted the quantitative approach with pre-test post-test control group true experimental design. The participants were composed of two calculus classrooms involving 31 and 24 students, respectively. The experimental group with 31 students received instruction with Geogebra while the control group received traditional instruction in learning the applications of derivative. Independent samples t-test was used in the analysis of the data gathered from students’ responses to Applications of Derivative Test which was subjected to them before and after teaching processes. The findings indicated that instruction with Geogebra had positive effect on students’ scores regarding conceptual knowledge and their overall scores. On the other hand, there was no significant difference between experimental and control group students’ scores regarding procedural knowledge. It could be concluded that students in both groups were focused on procedural knowledge to be successful in learning calculus subjects including applications of derivative in both groups. On the other hand, instruction with Geogebra supported students’ learning these subjects meaningfully and conceptually.

Limited information is available on the species composition, above ground biomass and its relations to grazing in a trans-Himalayan rangeland. Its assessment is essential for long term conservation and management. In the present study, we compared species composition, phenology, diversity index and biomass between controlled (without grazing) and open (free grazing) plots to assess the effects of grazing in the selected experimental sites of Upper Mustang during July and November 2005. Species encountered were classified as high, medium, low and non palatable and in three life form categories-grasses, shrubs and forbs. The experimental sites are dominated by forbs (80%) followed by grasses (15%) and shrubs (5%). Disturbance caused by grazing affects the phenological characteristics of the plant community. Result also reveals that species diversity, maximum possible diversity, evenness and species richness was higher in the grazed plots during July and November. A comparison of the aboveground biomass in July showed that mean percentage biomass of high, medium and low palatable species is higher in ungrazed plots. In November, the percentage biomass of only medium palatable species was higher in ungrazed plots and rest of the category is higher in grazed plots. Significant difference in July, a peak growing seasons for most of the plant species in the region reveals that the pasture has impact of livestock grazing.

The objective of this paper is to describe the prosodic features of the final intonation contour of minor intonational phrases (ip) and the tonemes of major intonational phrases (IP) in Mexico City’s Spanish variety. The speech data was taken from a spontaneous speech corpus made from speakers from two social networks: neighborhood and labor. Final intonation contours of ip show a predominantly rising movement. These contours are generally produced with greater length in the last syllable of the ip, which represents the most significant difference between both networks in the case of oxitone endings. On the other hand, tonemes are predominantly descendant, although the circumflex accent has an important number of cases within the data set. Tonemes produced by the neighborhood network are produced with larger length than those from the labor network.

Levels of lead-210, polonium-210, radium-226, and uranium are reported for 10 plant species (2 conifer, 4 shrub, 3 lichen, and 1 moss species) and soils in northern Saskatchewan. Two localities were studied in each of two regions, one uraniferous, the other not. Nonvascular species showed the highest levels of lead-210, polonium-210, and uranium, and the shrubs, the highest levels of radium-226. The lichen and moss species show no significant difference in accumulation of lead-210 and polonium-210 among regions, reflecting the assumed atmospheric distribution and particulate accumulation of these radionuclides. Seven of eight species for which comparisons could be made showed significant differences in uranium accumulation among regions. High levels in the lichen and moss species suggest that the primary source of uranium in these species is not directly from the soil. In contrast to the other radionuclides, radium-226 only showed significant differences among localities within regions, this being due to high accumulations occurring at one locality in the nonuraniferous region.

Is there a significant difference between Plato's texts and what is known as 'Platonism', that is, the philosophical tradition that claims Plato as its progenitor? Focusing on the Symposium, an attempt is made here to show that, far from merely fitting neatly into the categories of Platonism—with its neat distinction between the super-sensible and the sensible—Plato's own text is a complex, tension-filled terrain of countervailing forces. In the Symposium this tension obtains between the perceptive insights, on the one hand, into the nature of love and beauty, as well as the bond between them, and the metaphysical leap, on the other hand, from the experiential world to a supposedly accessible, but by definition super-sensible, experience-transcending realm. It is argued that, instead of being content with the philosophical illumination of the ambivalent human condition—something consummately achieved by mytho-poetic and quasi-phenomenohgical means—Plato turns to a putatively attainable, transcendent source of metaphysical reassurance which, moreover, displays all the trappings of an ideological construct. This is demonstrated by mapping Plato's lover's vision of 'absolute beauty' on to what Jacques Lacan has characterized as the unconscious structural quasi-condition of all religious and ideological illusion.

The distribution of calcium and phosphate in the cells of the enamel organ of the rat lower incisors was investigated by autoradiography and energy-dispersive x-ray spectrometry (EDS). Radioactive calcium or phosphate was injected i.p. into seven-day-old rats of the Wistar strain. The animals were frozen 0.5, 1, and 10 min after injection, and embedded in 5% carboxymethyl cellulose. Sagittal sections of 10 μm thickness were made in which the lower incisor was included as a part of the whole-body section. For autoradiography, the sections were freeze-dried and placed in contact with dry thin films prepared from autoradiographic emulsion. For EDS, sections were mounted on carbon stubs, freeze-dried, coated with carbon, and examined by EDS in a SEM. 45Ca and 32P autoradiograms showed that the radioactivity was located over the papillary layer cells adjacent to the secretory stage ameloblasts and was much higher here than in the ameloblastic layer. On the other hand, there was no significant difference between the amount of radioactivity of these two cell layers in the maturation stage, although higher radioactivity was detectable in the maturation stage enamel than in the secretory stage enamel. Pronounced Ka x-ray peaks were obtained for P, S, Cl, and K originating from the cells of the papillary and ameloblastic layers in the secretory stage, but only very low peaks were obtained for Ca. On the other hand, in addition to these elements, remarkably high Ca and Fe peaks could be detected in the ameloblastic layer of the maturation stage.

This research aims at examining and determining the effect of experience quality on tourists’ behavioral intention either directly or by perceived value, happiness, and tourist satisfaction. The sample in this research includes 227 tourists visiting Dodola Island using purposive sampling technique. The analytical method to test the hypothesis in this research is SEM-PLS. The results show that Experience Quality, Tourist Satisfaction, and Happiness had positive and significant effects on Tourists’ Behavior Intention. Meanwhile, Perceived value did not have any significant effect on Tourist Behavioral Intention as Perceived Value was not able to act as a mediator on the effect of Experience Quality on Behavioral Intention. On the other hand, Perceived Value variable had a positive and significant effect on Tourist Satisfaction. Therefore, the increase in Tourist Satisfaction sourced from Perceived Value could affect behavioral intention. The results of further research also show that Tourist Satisfaction and Happiness could partially mediate the effect of Experience Quality on Behavioral Intention.
