Evaluation of teenage pregnancy interventions in Wigan
This report presents the findings from a 12 month study that involved the development of an online questionnaire, and analysis of over 50 completed responses. The questionnaire aimed to determine the impact of a variety of services in Wigan that currently engage in strategies to reduce teenage pregnancy rates in the borough.
The report begins with the background and specific study aims and objectives followed by a policy and literature overview. Details of the study design and processes undertaken to develop the instrument are given, together with data collected from a number of participating sites. This data was analysed and the findings and recommendations are presented
Obtaining Atomic Matrix Elements from Vector Tune-Out Wavelengths using Atom Interferometry
Accurate values for atomic dipole matrix elements are useful in many areas of
physics, and in particular for interpreting experiments such as atomic parity
violation. Obtaining accurate matrix element values is a challenge for both
experiment and theory. A new technique that can be applied to this problem is
tune-out spectroscopy, which is the measurement of light wavelengths where the
electric polarizability of an atom has a zero. Using atom interferometry
methods, tune-out wavelengths can be measured very accurately. Their values
depend on the ratios of various dipole matrix elements and are thus useful for
constraining theory and broadening the application of experimental values.
Tune-out wavelength measurements to date have focused on zeros of the scalar
polarizability, but in general the vector polarizability also contributes. We
show here that combined measurements of the vector and scalar polarizabilities
can provide more detailed information about the matrix element ratios, and in
particular can distinguish small contributions from the atomic core and the
valence tail states. These small contributions are the leading error sources in
current parity violation calculations for cesium.Comment: 11 pages, 3 figure

Feeding Techniques To Increase Calf Growth In The First Two Months Of Life
End of project reportData from Cornell University and the University of Illinois in the USA suggested that average daily liveweight gains of 900 to 1000 g/calf/day could be achieved from birth to weaning provided the calf milk replacer (CMR) is formulated to meet the calf’s amino acid requirements for such a rate of gain. Their findings suggested a daily milk replacer DM allowance of 1250 to 1500 g/d with a crude protein content of 26 to 30%. A series of studies were undertaken, at ARINI with home born dairy calves and at Grange Beef Research Centre with purchased dairy calves, to determine the effect of increasing the daily milk replacer DM allowance and or increasing the crude protein content of the CMR on calf performance.The
main outcomes of these studies were
There was no growth or intake response in any of the studies to increasing the crude
protein content of the CMP from 23% to 28%.
Calf growth rates responded to increasing the dailymilk replacer allowance from 600
to 1200 g/day for both home bred and purchased calves. However, the effect was not
significant post-weaning in any of the studies.
In all of the studies (for both home reared and purchased calves) feeding a high level
of CMRdecreased concentrate DM intake. However, the calves concentrate intakes
were similar post-weaning.
The home bred calves with free access to the milk replacer feeders failed to consume
their 1200 g/day allowance. Calves offered 600 or 1200 g of CMR/day had average
consumption of 554 and 944 g/d, respectively, in the milk feeding period.
Feeding a high (1200 g/d) compared to a low level (600 g/d) CMRdiet for the first 56
days had no significant effect on carcass weight or carcass characteristics when
purchased male calves were slaughtered off an ad libitum concentrate diet after 388
days. The final carcass weights were 231 and 240 kg for the respective 600 and 1200
g/d CMR.
Reducing the fat content of the CMRfrom 18% to 12% did not have any effect on
concentrate intake or liveweight gain
Flutter: A finite element program for aerodynamic instability analysis of general shells of revolution with thermal prestress
Documentation for the computer program FLUTTER is presented. The theory of aerodynamic instability with thermal prestress is discussed. Theoretical aspects of the finite element matrices required in the aerodynamic instability analysis are also discussed. General organization of the computer program is explained, and instructions are then presented for the execution of the program

Building off encouraging data collected concerning ego permeability and smartphone audio/visual recording technology as a means to second language acquisition [Fallon/Baker, 2016; Keeley, 2014], this research explores the impact of extensive level-appropriate reading in combination with classroom recording and transcribing activities as a means to nourish language acquisition through self-reflective awareness and L2 identity development. This research will elaborate on the efficacy of continuous L2 reading assignments outside of class, verbal summarization of a story narrative, and L2 identity cultivation though metacognitive awareness. Data yielded from surveyed students found this approach to benefit intrinsic motivation and L2 ability. The same survey data also found metacognitive learning experiences to nourish L2 acquisition
第二言語クラスルームにおける映画とアニメーション : 第二言語習得における視聴覚メディアの有効性の探求
A popular pastime for many second language (L2) learners is watching movies, sitcoms, and animated films in their desired language to study. This affinity for watching films is apparent to most L2 educators, however the challenge becomes making such a passive participation activity into an appropriate challenge for a mixed level class of L2 learners. This exploratory review of an implemented class activity structure, which incorporates in-class L2 movie viewing and L2 discussion regarding the viewed material, has revealed positive results in regards to nourishing L2 acquisition. The following article will explain the method of this class structure, the efficacy of these methods based on survey results, as well as a review of the author’s thought structure and existing literature that lead to the implementation of this method
Water erosion control - 3
Contour Bank is the name applied to a ridge or bank of earth built across sloping ground between points of equal or nearly equal heights. The basic function of a contour bank is interception of run-off water is then either absorbed or conducted slowly from the land, depending on the condition of the soil conservation work contour banks are not a substitute for, but supplementary to, suitable plant cover and careful land management
