INFLUENCE OF TIERED LESSON AND GROUP PERSONALIZATION INSTRUCTIONAL STRATEGIES ON SENIOR SECONDARY SCHOOL STUDENTS’ ACHIEVEMENT IN MATHEMATICS

This study examined the Effects of Tiered Lesson Instructional Strategy (TLIS) and Group Personalization Instructional Strategies (GPIS) on Senior Secondary School Students Achievement in Mathematics. The moderating effects of mathematics anxiety and gender were also investigated. The study adopted the pretest-posttest, control group, quasi experimental design with a 3x3x2 factorial matrix. Three hundred and thirtyseven senior secondary two students from six public schools purposively selected participated in the study. Four null hypotheses were tested at 0.05 significance level. Four instruments were developed, validated and used for data collection. Data were analysed using Analysis of Covariance and Scheffe Post hoc test. The findings showed that treatment had significant effect on students’ achievement in Mathematics (F (2,318) =324.73, p<. 05). Students exposed to TLIS had the highest post achievement score. The study also revealed that Mathematics Anxiety (MA) had significant effect on Students’ achievement in Mathematics (F (3,333)=122.54,p<. 05). Students with low MA had the highest post achievement score. It also showed that gender had no significant effect on students’ achievement in Mathematics. Furthermore, the result of the 3-way interactions showed a significant interaction effects of treatment, mathematics anxiety and gender on students’ achievement in Mathematics (F(18,318) = 2.063, p < 0.05). Among the students in the TLIS group, those with low MA had highest post achievement scores. It was concluded that Mathematics teachers should be trained to use tiered lesson and group personalization learning packages in the classroom, since European Scientific Journal June 2014 edition vol.10, No.16 ISSN: 1857 – 7881 (Print) e ISSN 18577431 475 the strategies are effective in enhancing students’ achievement in Mathematics than the conventional method.
POLAR Observations of Two Pseudobreakup Events

The state-of-the-art plasma instruments on the POLAR spacecraft provide high resolution observations of short bursts of transverse plasma motion midway between the auroral acceleration region and the plasma sheet. At this location, short duration (< one minute) intervals of strong transverse ion convection are observed on the nightside during all phases of the substorm process. The most intense events are associated with substorm initiation and the passage of the expanding polar boundary over the POLAR satellite. This paper presents and discusses two intervals when the POLAR satellite was in or near the plasma sheet at the time of substorm onset. In both of these cases bursts of transverse plasma motion were observed approximately 10 minutes before substorm onset. We show that these events are pseudobreakup events. We describe the plasma and fields observed at POLAR during these events and show how these data can be used to distinguish among suggested pseudobreakup trigger mechanisms.
A Further Inquire about the Sustainability of Fiscal Policy in the EU

We analyse the sustainability of fiscal policy in EU15 countries in line with the recent literature on fiscal reaction functions. We test for a positive response of the primary surplus to accumulated debt using a baseline reaction function, and we check for robustness considering alternative specifications, estimation techniques, and possible structural breaks. We also estimate a Bayesian version of the baseline model as a way to provide an endogenous mechanism to analyse time variation in the response of governments to debt. We suggest that the posterior distribution of this model is a sensible indicator to assess the sustainability position of countries. Our conclusion is that the response to debt has fluctuated over the sample 1977-2005, but sustainability has been prevalent in EU15.
Prevalence of Hepatitis B virus infection among children attending mohammed shuwa memorial hospital Maiduguri, Borno state, Nigeria

Hepatitis B virus is a serious public health problem worldwide and major cause of chronic hepatitis, cirrhosis, and hepatocel lular carcinoma (HCC). This study was aimed to determined Hepatitis B virus infection among children attending Mohammed Shuwa Memorial Hospital Maiduguri. Out of one hundred serum samples tested, only 8 (8.0%) were positive to HBV. The distribution of hepatitis B virus based on age showed that those between 3 - 5years had higher prevalence of 3(6.7%), followed by 0 - 2years (12.5%), 6- 8 years (6.7%) and 9- 12years (6.3%). Male were more prevalent with hepatitis B virus infection 4 (10%) than their counterpart females 4(6.7%). A direct relationship between the educational status of the patients and the seroprevalence of HBV was observed, higher prevalence was recorded 5 (7.2%) among those that have undergone formal education than non -formal education. However, none of this variables were found to be risk factor of acquiring HBV infection (P>0.05). Th erefore, Hepatitis B virus vaccine should be recommended in all hospitals in Borno State to enable early detection and appropriate management of patients.
The Phenotypic Performances of Gerbera Local Bali X Rubby Red Hybrids

Gerbera is one of important cut flowers in floriculture industries. It can substitute of chrysanthemum. The novelty of cultivar and superiority of characteristic of gerbera are necessary in the floriculture markets. New cultivars can be created through hybridization between cultivars. This study aimed to find out the phenotypic performances of gerbera hybrids of Local Bali x Rubby Red. The research was conducted in Indonesian Ornamental Crops Research Institute, West Java, Indonesia from January 2014 to September 2015. Eight progenies of F1 hybrids and their parents (Local Bali and Rubby Red) were used as materials. In the hybridization process Local Bali and Rubby Red were used as female and male parents respectively. Genetic variabilities of Gerbera were achieved through this hybridization. Gerbera progeny no. 20.009 had the longest inflorescence diameter, the biggest outer sepal and the highest number of sepals compared to the others. The flower vase life of this progeny was not significantly difference to the male parent. Qualitative characters observation showed that the hybrids were classified into two groups based on flower type, four groups of outer ray florets and two-disc groups of petal color.
Magnetic correlations in paramagnetic iron

A method is described for calculating the extent of short-range order (SRO) in the paramagnetic state of magnetic transition metals. An energy V is calculated for a set of configurations of the exchange field. An entropy S is attached to each configuration; this is the logarithm of the number of configurations with the same degree of long- and short-range magnetic order. The SRO is then found by minimising the resulting free energy V-TS with respect to a near-neighbour correlation. The resulting Curie temperature TC and the magnetic entropy are in good agreement with experiment. The corresponding nearest-neighbour correlation is small (approximately cos 74 degrees ) at TC.
Effective‐medium theories for fluid‐saturated materials with aligned cracks

There is general agreement between different theories giving expressions for the overall properties of materials with dry, aligned cracks if the number density of cracks is small. There is also very fair agreement for fluid‐filled isolated cracks. However, there are considerable differences between two separate theories for fluid‐filled cracks with equant porosity. Comparison with recently published experimental data on synthetic sandstones gives a good fit with theory for dry samples. However, although the crack number density in the laboratory sample is such that first‐order theory is unlikely to apply, expressions correct to second order (in the number density) provide a worse fit. It also appears that the ratio of wavelength to crack size is not sufficiently great for any detailed comparison with effective‐medium theories, which are valid only when this ratio is large. The data show dispersion effects for dry cracks and scattering, neither of which will occur at sufficiently long wavelengths. Data from the water‐saturated samples indicate that the effect of equant porosity is significant, although the two theories differ strongly as to just how significant. Once again, and in spite of the reservations mentioned above, a reasonable fit between theory and observation can be shown.
A new Dendrolasma (Opiliones, Nemastomatidae) from Thailand

When searching for soil-dwelling spiders in the mountains of northern Thailand, a tiny opilionid was discovered which caused attention because of its peculiar ornamentation. Among other bizarre-looking forms, mostly of Laniatores, which are typically found in tropical forests, it stands out as a relative of the opilionid fauna of temperate regions and thus provides a zoogeographically highly interesting record. It is so far the only tropical species of the family Nemastomatidae, hitherto known to be holarctic in distribution. The record of Nemastoma emigratum Roewer from Madras, southern India, had been doubted by the author of the species himself. It is, most probably, based on a confusion of localities (cf. Roewer, 1959). Though unexpected, the finding of a nemastomatid in Thailand was not a complete surprise, for high altitude areas of the Southeast Asian tropics are known to house various species with close affinities to flora and fauna of temperate latitudes (Whitmore & Burnham, 1985: 251, 258). Further interesting discoveries from these localities can be expected. Abbreviations: MHNG = Museum d'Histoire naturelle, Geneve; NHMW = Naturhistorisches Museum, Wien.
Crucial ethical problem for Japanese nursing students at clinical settings

Background : Nursing students encounter ethical problems in their interactions with various people in clinical practice. In Japan, few studies have examined ethical problems between students and nursing educators in clinical practice. The aim of this study was to investigate the characteristics of ethical problems encountered by Japanese nursing students from the perspectives of patients and the students themselves. Methods : A descriptive, exploratory study was employed in this research. Questionnaires were distributed to 274 third-year students who had completed 6 months of clinical practice in 2012, 2013, or 2014. The situations in which students described ethical problems were classified into those involving patients and their family members and those involving the students themselves and other trainees. Results : A total of 58 students described 198 situations involving ethical problems (89 toward patients, 102 toward students, 7 other). Students expressed concern in terms of their basic attitudes toward nurses and respect for patient individuality. The largest number of unethical teaching behaviors involved violations of the principles of benevolence and respect for students. Conclusions : The results suggest the need for student assistance in understanding ethical problems, for strengthening of links with intramural ethics education, for the establishment of a consultation system, and for leveraging of faculty development education.
Abundance anomaly of the 13 C species of CCH

Aims. We have observed the N = 1−0 lines of CCH and its 13 C isotopic species toward a cold dark cloud, TMC-1 and a star-forming region, L1527, to investigate the 13 C abundances and formation pathways of CCH. Methods. The observations have been carried out with the IRAM 30 m telescope. Results. We have successfully detected the lines of 13 CCH and C 13 CH toward the both sources and found a significant intensity difference between the two 13 C isotopic species. The [C 13 CH]/[ 13 CCH] abundance ratios are 1.6 ± 0. 4( 3σ )a nd 1.6 ± 0. 1( 3σ )f or TMC-1 and L1527, respectively. The abundance difference between C 13 CH and 13 CCH means that the two carbon atoms of CCH are not equivalent in the formation pathway. On the other hand, the [CCH]/[C 13 CH] and [CCH]/[ 13 CCH] ratios are evaluated to be larger than 170 and 250 toward TMC-1, and to be larger than 80 and 135 toward L1527, respectively. Therefore, both of the 13 C species are significantly diluted in comparison with the interstellar 12 C/ 13 C ratio of 60. The dilution is discussed in terms of a behavior of 13 Ci n
Comparison of Assessment Scores of Candidates for Communication Skills in an OSCE, by Examiners, Candidates and Simulated Patients

Though OSCE method has been verified by several researchers for the appropriate assessment of competence in clinical skills, yet medical educationists have some concerns regarding the value of assessment of communication skills and empathy by this method. Hence, we sought to assess the extent of differences, if any, among the examiners, the candidates and the simulated patients (SPs) for communication skills. A total of 23 general practitioners, who were preparing for their postgraduate clinical examination, participated in a practice OSCE on seven stations in this study. The examiners observed and evaluated the candidates during the whole consultation, using the pre-tested checklist including 15 items with a global rating scale. The simulated patients also evaluated the candidates at the end of consultation, using the same checklist. There were significant differences in the assessment scores of candidates by the examiners, the candidates themselves and the simulated patients regarding all aspects of communication skills. However, introduction to the patient’s scenario of some non-verbal communication did not show any significant difference (p-value => 0.05). The correlation between examiners and SPs (r = 0.07, p = 0.7) and SPs and candidates (r = 0.01, p = 0.95) was very low and not significant. Cronbach’s alpha was 0.968 across items, whereas among seven stations it was 0.931. This study has shown a significance difference in assessment scores of candidates by examiners, SPs and candidates themselves. In conclusion, there is a need for further research regarding the active role of SPs in summative assessments.
Alternative methods in tracking sources of microbial contamination in waters

A key factor in the management and remediation of impaired ground- and surface water is the ability to distinguish the sources of faecal contamination. Several approaches have been adopted as microbial source tracking methods (MST), which are generally classified as culturing, phenotypic, genetic, and chemical MST. None of the techniques used thus far can be considered a standard; important factors, such as the statistical correlation between the source and the faecal indicator and the understanding of the environmental fate of the faecal pollutants, still need attention. The most promising MST methods available today are based on the genetic fingerprinting of faecal micro-organisms. However, research is very active also in the investigation of pharmaceuticals and personal care products discharged in the environment together with faecal waste. An updated overview of MST methods to distinguish human from animal sources of faecal pollution is presented here, focusing particularly on the potentialities of new chemical tracers.
Intra-industry agri-food trade of the Baltic Countries

The article analyses patterns and country-specific determinants of the Baltic Countries agri-food trade with the European Union. Literature focusing on the country-specific determinants of vertical and horizontal intra-industry trade is rather limited and those analysing agricultural (or agri-food) trade are extremely rare. Therefore, the paper seeks to contribute to the literature by covering latest theory and data available on the topic to provide up to date results and suggestions. Moreover, it seeks to identify the determinants of horizontal and vertical intra-industry trade of the Baltic Countries after EU accession. Results suggest that agri-food trade of these countries is mainly inter-industry in nature but intra-industry trade is dominated by vertical elements. Results verify that determinants of horizontal and vertical IIT differ and suggest that economic size is positively, while factor endowments and distance are negatively related to both sides of IIT. However, the relationship between IIT and FDI is ambiguous.
Preglacial to glacial sediment thickness grids for the Southern Pacific Margin of West Antarctica

Circum‐Antarctic sediment thickness grids provide constraints for basin evolution and paleotopographic reconstructions, which are important for paleo‐ice sheet formation histories. By compiling old and new seismic data, we identify sequences representing preglacial, transitional, and full glacial deposition processes along the Pacific margin of West Antarctica. The preglacial sediment grid depicts 1.3–4.0 km thick depocenters, relatively evenly distributed along the margin. The depocenters change markedly in the transitional phase at, or after, the Eocene/Oligocene boundary when the first major ice sheets reached the shelf. Full glacial sequences, starting in the middle Miocene, indicate new depocenter formation North of the Amundsen Sea Embayment and localized eastward shifts in the Bellingshausen Sea and Antarctic Peninsula basins. Using present‐day drainage paths and source areas on the continent, our calculations indicate that an estimated observed total sedimentary volume of ∼10 × 106 km3 was eroded from West Antarctica since the separation of New Zealand in the Late Cretaceous. Of this, 4.9 × 106 km3 predates the onset of glaciation and need to be considered for a 34 Ma paleotopography reconstruction. Whereas 5.1 × 106 km3 postdates the onset of glaciation, of which 2.5 × 106 km3 were deposited in post mid‐Miocene full glacial conditions.
Rheological Characterization of Polyanionic Cellulose Solutions with Application to Drilling Fluids and Cuttings Transport Modeling

Abstract In petroleum drilling, aqueous Polyanionic Cellulose solutions (PAC) are often used as a drilling fluid model system in experimental laboratory studies to investigate cuttings transport. Cuttings transport refers to the transportation of drilled-off solids out of the wellbore. In these studies, PAC solutions are typically assumed to behave purely viscous, i.e. they do not show time-dependent/thixotropic and/or viscoelastic properties. In this study, a rheological characterization of PAC has been performed in combination with an evaluation of time scales characterizing the fluid to verify the conventional assumption of a purely-viscous fluid. It is found that PAC solutions are generally not purely viscous: They feature viscoelastic behavior on time scales of the order of 0.01 to 1 s, such as normal stress differences, as well as thixotropic behavior on larger time scales of the order of 10 to 1000 s because of their polymeric microstructure. If simplified to a purely viscous fluid, the degree of uncertainty in representing the measured apparent shear viscosity may increase by an order of ≈ 75 to 90 % depending on the relevant time scale. When obtaining flow curves, a sufficiently long measurement point duration (sampling time for a particular torque reading) is required to ensure that the liquid microstructure has reached its dynamic equilibrium at the desired shear rate. Due to their polymeric nature, PAC solutions feature Newtonian viscosity plateaus at both low and high shear rates. For modeling purposes, the application of a Cross/Carreau material function is recommended because it both best describes the flow curve data and minimizes extrapolation errors compared to the conventionally used Power Law material function.
Impact of a simulated practice program in the construction of self-confidence for intervention in emergencies and its association with knowledge and performance

The objective was to assess the impact of a simulated practice program on the construction of self-confidence for intervention in emergencies and its association with knowledge and performance. This is a quasi-experimental study without control group, with assessment before and after a 15-hour simulated practice program, in nursing students. The students’ self-confidence increased significantly as a result of simulated practice with positive and statistically significant association between practical assessment and self-confidence levels.
Ecological Restoration and Reforestation of Fragmented Forests in Kianjavato, Madagascar

A reforestation effort in Kianjavato Commune in southeast Madagascar is presented that combines native diversity with rapidly growing introduced and native pioneer trees. This work utilizes a three-tiered corridor design that capitalizes on the region’s mountainous terrain. The process of seed selection, transplantation, and survival rate of seedlings over a 16 month period is reported. The uppermost 50% of each mountain is planted with 38 woody species and most closely approximates native forest. This tier was divided into two categories, pioneer and secondary species. Most of the pioneer species were not native; however, results showed that four fast-growing, environmentally-tolerant native species could be suitable alternatives: Streblus mauritianus, Syzygium bernieri, Treculia madagascariensis and Uapaca thouarsii. More than 70,000 seeds of secondary species were extracted from fecal samples from wild, free-ranging black and white ruffed lemurs; the majority of which germinated significantly better after gut passage. The most effective pretreatment that enhanced germination was to scarify unwashed seeds. Commercially valuable trees, belonging to the community members, were grown on the lower half of each mountain. Lastly, the various contributions of the community are described along with agroforestry development plans designed to reduce pressure on forest resources and generate supplemental income.
Spectrum and outcome of gastric outlet obstruction in a tertiary care hospital

Wallace P Richie Jr called stomach an elegant organ, once thought to be the seat of the soul, always handy to bring to the dinner table, and a recognised source of ecstasy and grief. Gastric outlet obstruction is a disorder wherein there is an obstruction in the opening of the stomach (Pylorus), blocking the entrance of ingested food coming from the stomach to the duodenum. Gastric outlet obstruction is the one of the most common clinical scenarios encountered in general surgery. Pyloric obstruction occurs in 2-4% of patients with chronic duodenal ulcer and it is described by Sir James Walton as “the stomach you can hear, the stomach you can feel and ABSTRACT
Optimal Placement of MEMS Sensors for Damage Detection in Composite Plates

Objective: Inertial Micro Electro-Mechanical Systems (MEMS) have recently been proposed as sensing components of surface-mounted structural health monitoring systems aimed to detect damage in flexible plates, subjected to either quasi-static or dynamic loadings. Method: In this paper, we discuss a topology optimization approach to smartly deploy an array of MEMS accelerometers over thin flexible plates, partially allowing for scattering in their placement. Result: We assume damage (i.e. a reduction of the local bending stiffness of the plate) to be located anywhere, and we show how boundary conditions, symmetry conditions and the stacking sequence in case of a composite laminate can affect the optimal sensor placement.
