Generalized inequalities on warped product submanifolds in nearly trans-Sasakian manifolds
In this paper, we study warped product submanifolds of nearly trans-Sasakian
manifolds. The non-existence of the warped product semi-slant submanifolds of
the type is shown, whereas some characterization and
new geometric obstructions are obtained for the warped products of the type
. We establish two general inequalities for the
squared norm of the second fundamental form. The first inequality generalizes
derived inequalities for some contact metric manifolds [16, 18, 19, 24], while
by a new technique, the second inequality is constructed to express the
relation between extrinsic invariant (second fundamental form) and intrinsic
invariant (scalar curvatures). The equality cases are also discussed.Comment: 16 page
Exploring pupils' views of primary school in Year 5
A range of information about pupils’ self-perceptions and views of their primary school
were collected as part of the Effective Provision of Pre-school and Primary Education
(EPPE 3-11) Project. The EPPE 3-11 study is funded by the Department for Children,
Schools and Families (DCSF) and has followed children’s development from pre-school
through to the end of primary school and explored evidence of educational influences in
pre-school and primary school, as well as the impact of child, family and home learning
environment (HLE) characteristics as predictors of pupils’ outcomes (attainment,
social/behavioural development and self-perceptions). In Year 5 the ‘All About Me and My
School’ questionnaire included information about pupils’ views of their primary school. A
range of statistical methods has been used to investigate results for 2528 pupils for whom
at least one pupils’ views of primary school outcome measure was collected in Year 5
Influences on pupils' self-perceptions in primary school: enjoyment of school,anxiety and isolation, and self-image in year 5
This report presents the results of analyses of pupils’ self-perceptions in primary school. It
is part of the longitudinal Effective Pre-school and Primary Education 3-11 (EPPE 3-11)
research project funded by the Department for Children, Schools and Families (DCSF).
The focus of this report is pupils’ self-perceptions in Year 5 (age 10) in four key areas:
‘Enjoyment of school’; ‘Academic self-image’; ‘Behavioural self-image’ and ‘Anxiety and
Isolation’. Reports on pupils’ cognitive and social/behavioural development at this age
have been published separately (Sammons et al., 2007a; 2007b).
The original EPPE sample was recruited to the study at age 3 years plus and monitored to
the end of Key Stage 1 (Year 2) in primary school. An additional ‘home’ sample of
children (who had not attended a pre-school setting) was recruited when the pre-school
sample started primary school. The EPPE 3-11 extension is following up the sample to
the end of primary school (age 11 years plus). In addition to exploring pre-school
influences, EPPE 3-11 research identifies the influence of primary school on a range of
pupils’ educational outcomes, as well as investigating any continuing pre-school effects.
EPPE 3-11 involves the collection and analysis of a range of data about pupils’
development, child, family and home learning environment (HLE) characteristics and the
characteristics of the schools attended. Additional value added measures of primary
school academic effectiveness have been derived from independent statistical analyses of
National data sets conducted for all primary schools in England (Melhuish et al., 2006) as
part of the study. These have been incorporated into the EPPE 3-11 child database to
provide indicators of the academic effectiveness of primary schools attended which
complement the measures on pre-school settings. Thus, it is possible to explore both preschool and primary school influences on pupils’ outcomes in Year 5.
Questionnaires were administered to children asking their views about school and
classroom life. These provided measures of pupils’ self-perceptions in Year 2 and again
in Year 5 in terms of ‘Enjoyment of school’, ‘Anxiety and Isolation’ and ‘Academic selfimage’ and ‘Behavioural self-image’. A range of statistical methods have been used to
investigate results for 2520 pupils for whom at least one self-perception outcome measure
was collected in Year 5
GC-MS Analysis of Insecticidal Leaf Essential Oil of Pyrenacantha Staudtii Hutch and Dalz (Icacinaceae)
Purpose: Insecticides have been known to cause serious toxicological and environmental problems. Hence, the insecticidal activity and chemical composition of a local medicinal plant was investigated.Methods: Steam distillation of P.staudtii leaves was carried out using a Clavenger apparatus in order to obtain the volatile oils. Gas chromatography/mass spectrometric (GC/MS) analyses (DB-5 Optima-5 column) of the essential oil were performed and its insecticidalactivity determined.Results: GC-MS spectrometry showed that the major chemical components of the oil were tetradecanoic acid (22 %), hexanoic acid, α-phellandrene (13 %), and citronellol sp. (7 %). The work also revealed significant insecticidal activity of 80 % and 60 % against Rhyzoperthadominica and Tribolium castaneum, respectively.Conclusion: The study established the chemical composition and insecticidal activity of the essential oil of the plant leaf. Future formulation studies, toxicity profile and possible mechanism of action may lead to the development of a potential insecticidal product
Effective Pre-school, Primary and Secondary Education 3-14 Project (EPPSE 3-14): influences on students’ dispositions in Key Stage 3: exploring enjoyment of school, popularity, anxiety, citizenship values and academic self-concept in Year 9
The Effective Pre-school, Primary and Secondary Education Project (EPPSE) has investigated the academic and social-behavioural development of approximately 3,000 children from the age of 3+ years since 1997. This Report and Research Brief reports on students’ dispositions when they were age 14 (Year 9) in six main areas: ‘enjoyment of school’, ‘academic self concept’ (English and maths), ‘popularity’, ‘citizenship values’ and ‘anxiety’. It examines how these dispositions have changed during Key Stage 3 (KS3) and the relationships between dispositions and a range of individual student, family, home, pre-, primary and secondary school measures. It shows how school experiences help to shape dispositions, and also explores the relationships between dispositions to school and students’ academic and social-behavioural outcomes. The findings highlight the importance of the ‘student voice’ and provides an insight into the experiences of teenagers in the first decade of the 21st Century
Influences on students’ attainment and progress in Key Stage 3: academic outcomes in English, Maths and Science in Year 9
The Effective Pre-school, Primary and Secondary Education Project (EPPSE) has investigated the academic and social-behavioural development of approximately 3,000 children from the age of 3+ years since 1997. This Research Brief focuses on the relationships between a range of individual student, family, home, pre-, primary and secondary school characteristics and students\u27 academic attainment in English, maths and science in Year 9 at secondary school (age 14). It compares the latest findings with those found for students\u27 attainment at younger ages. It also highlights the influences of secondary school on students\u27 attainment in the core curriculum areas and studies their academic progress across Key Stage 3 between the ages of 11 and 14
Effective pre-school, primary and secondary education project (EPPSE 3-14): students’ reports of their experiences of school in Year 9
The Effective Pre-school, Primary and Secondary Education Project (EPPSE) has inves tigated the academic and social
behavioural (+ in the later stages the affective)
development of approximately 3,000 children from the age of 3+ years since 1997. This report presents the results of analyses related to student’s experiences in Year 9 (age 14), with the purpose of creating measures of both school and classroom life as experienced by students. These measures have been used in the analysis of academic and social-behavioural outcomes as well as dispositions to investigate whether a student’s reported experience of school can significantly predict outcomes in other areas. The findings highlight the importance of the ‘student voice’ and provide an insight into the experiences of teenagers in the first decade of the 21st Century
