Mobile learning has increasingly become interwoven into the fabric of learning and teaching in the United Kingdom higher education sector, and as technological issues become addressed, this phenomena has accelerated. The aim of the study was to examine whether learning using a mobile learning device (Samsung NC10 Netbook) loaded with interactive exercises promoted learning compared with a traditional library exercise. Using a randomized trial, 55 students from an undergraduate sports science course ( n = 28) and medical course ( n = 27) volunteered to participate in this study. A mixed-model design ANOVA was used to examine the percent change in test score after a 3-wk intervention. Results showed that there was a significant difference between the two courses ( P < 0.001), methods ( P = 0.01), and trials ( P < 0.001). The findings suggested that both methods augmented student knowledge and understanding in sports science and medical students. The sports science group demonstrated proportionally greater increases in test performance when exposed to the mobile interactive intervention compared with the traditional library approach. Qualitative data suggest an increased level of engagement with the Netbooks due to the stimulating interactive content. In conclusion, the Netbooks were an effective additional learning tool, significantly enhancing knowledge and understanding in students. Further research should ensure that participants are assessed for preferred learning styles, the subjective task value of expectancy value, and readiness for mobile learning to ascertain if this has an effect on the potential for using mobile learning and interactivity.

The study employed a mixed method research design to investigate the self-perceived levels of learners’ autonomy at the institution where the researcher works. The study also explores the teachers’ support in fostering students’ autonomy. In addition, the study attempts to determine the relationship between genders, learning styles and the learners’ levels of autonomy. The main findings reveal that the level of learners’ autonomy where the study was conducted was at medium level (M = 2.66 out of 5.0 scale). In terms of the students’ perception of their teachers’ roles in fostering students’ autonomy, the finding of the current study reveals that it was quite supportive (M = 3.29 out of 5.0 scale). The finding also indicated that the difference in level of autonomy is not significant between male and female students (M = 2.667 for male compared with M = 2.668 for female students). Finally, the result showed that there a statistically significant difference in the levels of autonomy between students with different learning styles. To be specifically, the students who prefer kinesthetic learning style possess the highest level of autonomy (M = 2.75) compared with M = 2.60 and 2.59 for visual and individual learning style students. M=2.72; M=269 and M=2.62 are the level of autonomy for group, tactile and auditory students respectively.

The purpose of this study is to identify the relationship between students’ views on homework and their learning styles. The study follows a descriptive survey model. It is also an example of descriptive study in relational screening model. Target population is all first, second, third, and fourth year students who are enrolled in Çukurova University Primary School Classroom Teaching Department. The participants are 443 students who volunteered to fill in the data collection forms used in the study. Of the participants, 90 were first year, 103 were second year, 140 were third year, and 110 were fourth year students. 275 of the students participating in the study were female (62.1%) and 168 were male (37.9%). The data were collected through “Homework Attitudes Scale” developed by Gündüz (2005), Kolb’s Learning Styles Inventory (LSI) which was first examined for its applicability in Turkey by Aşkar and Akkoyunlu (1993), “Homework Purpose Scale”, “Homework Management Scale” and “Personal Information Form” developed by the researcher. No instruments were used to measure students’ academic success levels; their academic success was identified according to the overall mean score obtained from the scores they received from all lessons. Findings show that 141 students (31.8%) preferred assimilating learning style while 133 students (30%) preferred converging learning style. Dominant learning style was found to differ according to grade level and grade point average. The difference in terms of homework attitudes, homework purpose, and homework management scale mean scores was in favour of mostly students who have converging learning style. Besides, there was a significant difference in terms of doing homework on time in favour of students who have converging learning style, and there was a significant difference in terms of coming to class without homework in favour of students who have diverging learning style.

Crassicauda spp. (Nematoda) infest the cranial sinuses of several odontocetes, causing diagnostic trabecular osteolytic lesions. We examined skulls of 77 Indian Ocean humpback dolphins Sousa plumbea and 69 Indo-Pacific bottlenose dolphins Tursiops aduncus, caught in bather-protecting nets off KwaZulu-Natal (KZN) from 1970-2017, and skulls of 6 S. plumbea stranded along the southern Cape coast in South Africa from 1963-2002. Prevalence of cranial crassicaudiasis was evaluated according to sex and cranial maturity. Overall, prevalence in S. plumbea and T. aduncus taken off KZN was 13 and 31.9%, respectively. Parasitosis variably affected 1 or more cranial bones (frontal, pterygoid, maxillary and sphenoid). No significant difference was found by gender for either species, allowing sexes to be pooled. However, there was a significant difference in lesion prevalence by age, with immature T. aduncus 4.6 times more likely affected than adults, while for S. plumbea, the difference was 6.5-fold. As severe osteolytic lesions are unlikely to heal without trace, we propose that infection is more likely to have a fatal outcome for immature dolphins, possibly because of incomplete bone development, lower immune competence in clearing parasites or an over-exuberant inflammatory response in concert with parasitic enzymatic erosion. Cranial osteolysis was not observed in mature males (18 S. plumbea, 21 T. aduncus), suggesting potential cohort-linked immune-mediated resistance to infestation. Crassicauda spp. may play a role in the natural mortality of S. plumbea and T. aduncus, but the pathogenesis and population level impact remain unknown.

Abstract: Routine blood examination is the earliest blood test or screening test to determine the diagnosis of an abnormality. Blood easily froze if it is outside the body and can be prevented by the addition of anticoagulants, one of which Ethylene Diamine Tetra Acetate (EDTA). Currently available vacuum tubes containing EDTA anticoagulants in the form of K2EDTA and K3EDTA. K3EDTA is usually a salt that has better stability than other EDTA salts because it shows a pH approaching a blood pH of about 6.4. The purpose of this research is to know the difference of erythrocyte index results include MCH, MCV and MCHC using K3EDTA anticoagulant with K2EDTA. This research is a cross sectional design. This study used venous blood samples mixed with K2EDTA anticoagulant and venous blood mixed with K3EDTA anticoagulants, each of 30 samples. Data were collected and analyzed using paired different test. Based on data analysis that has been done on MCH examination, p value <0,05 then there is a significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value. Then on the examination of MCV and MCHC obtained p value <0.05 then there is no significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value.Abstrak: Pemeriksaan darah rutin merupakan pemeriksaan darah yang paling awal atau screening test untuk mengetahui diagnosis suatu kelainan.
