Greater return on women's enterprise (GROWE) : final report and recommendations of the women's enterprise task force. SEEDA, womenâs enterprise task force.
This Womenâs Enterprise Task Force (WETF) report, Greater Return On Womenâs Enterprise (GROWE), sets out the economic case for womenâs enterprise and advises partners and stakeholders how to achieve a greater economic return from investment in womenâs enterprise. The Task Force has framed its recommendations to maximise existing investment and resources. We are mindful of the Governmentâs Business Support Simplification Programme and the effect the recession will continue to have on public spending, and so suggest that relevant Government departments and private sector organisations work together to streamline support and make best use of existing investment. In providing thought leadership to increase the quantity, scalability and success of womenâs enterprise in the UK, the WETF has informed the national agenda on womenâs enterprise for the last three years, concentrating its efforts on five specific Pillars: 1. gender-disaggregated business data 2. female-friendly business support 3. access to finance and technology 4. supplier diversity and procurement 5. strategic influencing and awareness raising. WETF highlights of the past three years include paving the way for a Business Link national data disaggregation methodology whilst influencing and shaping the establishment, direction and implementation of Aspire, a ÂŁ12.5m womenâs co-investment fund to support high-growth women-owned businesses. Alongside this, the WETF has played an important role in raising awareness of the economic case for womenâs enterprise and the potential of female entrepreneurs in aiding the UKâs economic recovery. Perhaps most importantly, the WETF met with the Prime Minister and saw important policy developments taken forward in the Governmentâs Enterprise Strategy of March 2008. In 2009 the WETF contributed to the enterprise knowledge bank by producing two research reports into womenâs enterprise: Impact of the Recession on Womenâs Enterprise and Myths and Realities of Womenâs Access to Finance. The Task Force welcomes progress made by the Ethnic Minority Business Task Force (EMBTF) in the advocacy of complementary areas which include the need for access to finance, disaggregated data and supplier diversity. Much of the groundwork for the WETFâs work was laid out in the Governmentâs 2003 publication, A Strategic Framework for Womenâs Enterprise. In 2003, it was estimated that women constituted around 27% of self-employed people in the UK, and that only 12-14% of businesses were majority-owned by women (compared to 28% in the USA). From the Strategic Framework for Womenâs Enterprise, to the establishment of the WETF and the Enterprise Strategy, Government has shown the importance that it attaches to women in enterprise and its recognition of the increased economic benefits women can contribute to UK plc. This must be even more important in emerging from recession. Recently, Government has a produced a policy statement, Building Britainâs Future: New Industry, New Jobs (NINJ), which sets out Governmentâs vision for economic recovery and growth by targeted intervention aimed at hightech, high-growth firms. The WETF has several recommendations for how enterprising women can take advantage of these interventions. Enterprise has a significant role to help women remain economically active and increase the productivity and international competitiveness of the UK. Recent figures from 2009 show that women, who make up 46% of the workforce, now constitute nearly 29% of the self-employed in the UK (up 2 percentage points). 15% of the 4.8 million enterprises in the UK are now majority-led by women. The longer-term quantitative targets outlined in the Framework included women accounting for 40% of customers using Government sponsored business support services; and women-owned businesses accounting for 18-20% of the UK total. Government has gone some way towards achieving these targets. Today, women-owned businesses account for around one third of Business Link customers, a major increase on the 22.3% or nearly 150,000 women customers in Q1 of 2005/6. However, overall progress has been very slow and neither of the Framework targets set for completion by 2006 has yet been met. More work needs to be done to address this and the other issues facing womenâs enterprise today. This report examines how to further increase the current ÂŁ70 billion Gross Value Added (GVA) and ÂŁ130 billion turnover annual contribution made by womenâs enterprise to the UK economy. Recent figures suggest that 900,000 more businesses would be created if the UK achieved the same levels of female entrepreneurship as in the US, resulting in an additional ÂŁ23 billion GVA to the UK economy, thus largely closing the productivity gap with the US.1 In Britain alone, 150,000 extra businesses would be created per annum if women started businesses at the same rate as men.2 This is especially pertinent in this time of recession. With effective, targeted support, increasing the number of women entrepreneurs will be an important factor in driving economic recovery
Reduction of N-Protected Amino Acids to Amino Alcohols and Subsequent Re-Oxidation to Original N-Protected Amino Acids
For the synthesis of certain molecules of interest in Dr. Richard Olsen\u27s laboratory it was necessary to produce N-protected a-amino alcohols from N-protected amino acids and subsequently, after further synthesis steps, to oxidize the hydroxyl functionalities of these molecules back to carboxylic acids. A number of methods are known for the reduction of carboxylic acids to alcohols; several methods are also reported in the chemical literature for the oxidation of alcohols to carboxylic acids. The problem in finding a suitable general method, is that the amino acid side chains affect the re activity and chemistry differently in each specific case. I report a method that has been shown to be effective for the reduction and subsequent re-oxidation of a number of N-carbobenzoxy and N-tert-butyloxycarbonyl protected amino acids
Quantum effects on Higgs-strahlung events at Linear Colliders within the general 2HDM
The associated production of neutral Higgs bosons with the Z gauge boson is
investigated in the context of the future linear colliders, such as the ILC and
CLIC, within the general two-Higgs-doublet model (2HDM). We compute the
corresponding production cross-sections at one-loop, in full consistency with
the available theoretical and phenomenological constraints. We find that the
wave-function renormalization corrections to the external Higgs fields are the
dominant source of the quantum effects, which turn out to be large and
negative, and located predominantly in the region around \tan\beta=1 and
moderate values of the parameter \lambda_5 (being \lambda_5 < 0). This behavior
can be ultimately traced back to the enhancement potential of the triple Higgs
boson self-couplings, a trademark feature of the 2HDM with no counterpart in
the Higgs sector of the Minimal Supersymmetric Standard Model. The predicted
Higgs-strahlung rates comfortably reach a few tens of femtobarn, which means
barely 10^3 - 10^4 events per 500 inverse femtobarn of integrated luminosity.
Due to their great complementarity, we argue that the combined analysis of the
Higgs-strahlung events and the previously computed one-loop Higgs-pair
production processes could be instrumental to probe the structure of the Higgs
sector at future linac facilities.Comment: LaTeX, 16 pages, 9 Figures, 2 Tables. Extended discussion, references

A review of approaches to estimate wildfire plume injection height within large-scale atmospheric chemical transport models
Landscape fires produce smoke containing a very wide variety of chemical species, both gases and aerosols. For larger, more intense fires that produce the greatest amounts of emissions per unit time, the smoke tends initially to be transported vertically or semi-vertically close by the source region, driven by the intense heat and convective energy released by the burning vegetation. The column of hot smoke rapidly entrains cooler ambient air, forming a rising plume within which the fire emissions are transported. The characteristics of this plume, and in particular the height to which it rises before releasing the majority of the smoke burden into the wider atmosphere, are important in terms of how the fire emissions are ultimately transported, since for example winds at different altitudes may be quite different. This difference in atmospheric transport then may also affect the longevity, chemical conversion, and fate of the plumes chemical constituents, with for example very high plume injection heights being associated with extreme long-range atmospheric transport. Here we review how such landscape-scale fire smoke plume injection heights are represented in larger-scale atmospheric transport models aiming to represent the impacts of wildfire emissions on component of the Earth system. In particular we detail (i) satellite Earth observation data sets capable of being used to remotely assess wildfire plume height distributions and (ii) the driving characteristics of the causal fires. We also discuss both the physical mechanisms and dynamics taking place in fire plumes and investigate the efficiency and limitations of currently available injection height parameterizations. Finally, we conclude by suggesting some future parameterization developments and ideas on Earth observation data selection that may be relevant to the instigation of enhanced methodologies aimed at injection height representation
Flight Dynamics of the flying wing
Flying wings are one of the most promising concepts for the future of commercial aviation, regarding the market, technology and environmental driving factors. The research reported here is part of a long term project on the 300 seats category flying wings. In several previously published works the feasibility, efficient performance and airport compatibility of the concept have been assessed. The present paper concentrates on the flight dynamic aspects of the aircraft, which have been scarcely analyzed in open literature. The results obtained show that the flying wing configuration can be dynamically stable; however, the longitudinal and lateral directional oscillations decay so slowly that a stability augmentation system would be required to assure an acceptable dynamic response of the aircraft
Structural Recursion as a Query Language
We propose a programming paradigm that tries to get close to both the semantic simplicity of relational algebra, and the expressive power of unrestricted programming languages. Its main computational engine is structural recursion on sets. All programming is done within a nicely typed lambda calculus, as in Machiavelli [OBB89]. A guiding principle is that how queries are implemented is as important as whether they can be implemented. As in relational algebra, the meaning of any relation transformer is guaranteed to be a total map taking finite relations to finite relations. A naturally restricted class of programs written with structural recursion has precisely the expressive power of the relational algebra. The same programming paradigm scales up, yielding query languages for the complex-object model [AB89]. Beyond that, there are, for example, efficient programs for transitive closure and we are also able to write programs that move out of sets, and then perhaps back to sets, as long as we stay within a (quite flexible) type system. The uniform paradigm of the language suggests positive expectations for the optimization problem. In fact, structural recursion yields finer grain programming. Therefore we expect that lower-level and therefore better optimizations will be feasible

Measuring molecular abundances in comet C/2014 Q2 (Lovejoy) using the APEX telescope
Comet composition provides critical information on the chemical and physical
processes that took place during the formation of the Solar system. We report
here on millimetre spectroscopic observations of the long-period bright comet
C/2014 Q2 (Lovejoy) using the Atacama Pathfinder Experiment (APEX) band 1
receiver between 2015 January UT 16.948 to 18.120, when the comet was at
heliocentric distance of 1.30 AU and geocentric distance of 0.53 AU. Bright
comets allow for sensitive observations of gaseous volatiles that sublimate in
their coma. These observations allowed us to detect HCN, CH3OH (multiple
transitions), H2CO and CO, and to measure precise molecular production rates.
Additionally, sensitive upper limits were derived on the complex molecules
acetaldehyde (CH3CHO) and formamide (NH2CHO) based on the average of the
strongest lines in the targeted spectral range to improve the signal-to-noise
ratio. Gas production rates are derived using a non-LTE molecular excitation
calculation involving collisions with H2O and radiative pumping that becomes
important in the outer coma due to solar radiation. We find a depletion of CO
in C/2014 Q2 (Lovejoy) with a production rate relative to water of 2 per cent,
and relatively low abundances of Q(HCN)/Q(H2O), 0.1 per cent, and
Q(H2CO)/Q(H2O), 0.2 per cent. In contrast the CH3OH relative abundance
Q(CH3OH)/Q(H2O), 2.2 per cent, is close to the mean value observed in other
comets. The measured production rates are consistent with values derived for
this object from other facilities at similar wavelengths taking into account
the difference in the fields of view. Based on the observed mixing ratios of
organic molecules in four bright comets including C/2014 Q2, we find some
support for atom addition reactions on cold dust being the origin of some of
the molecules.Comment: 10 pages, 7 figures, to be published in MNRA
Relation among Caregiversâ Burden, Abuse and Behavioural Disorder in People with Dementia
Dementia produces a loss of independence to carry out the activities of daily life. The great demand for care that these people need usually falls on the family through informal care. This study aims to analyse the burden showed by the informal caregiver of a person with dementia. In addition, we analyse whether this burden present in informal caregivers could be related to abusive behaviour. We also study the relationship between the stage of the disease, the appearance of behavioural disorders and the level of burden in the caregiver using the Scales of Zarit, CASE and FAST. The data showed that 45.50 per cent of caregivers have light burden or burden. After the research, it was identified that the presence of behavioural disorders in patients with dementia showed a correlation with the increase in both the main caregiver burden and abuse. An increase in the level of burden is followed by an increase in the level of abuse (r = 0.844; p = 0.000). Furthermore, we analysed several conditions that could have a correlation with this burden and abuse. It was found that burden in the caregiver could be linked with the presence of behavioural disorders, like aggression (r = 0.577; p = 0.008) and irritability (r = 0.600; p = 0.005) at the moderate stage of the disease. On the other hand, there is a positive correlation between the probability that people with dementia suffer abuse in the moderate stage of the disease and the presence of aggression (r = 0.732; p = 0.000), lack of inhibition (r = 0.571; p = 0.009) and irritability (r = 0.827; p = 0.000). Taking this data into account, burden and abuse seem to be linked to the presence of behavioural disorders in patients with dementia in the moderate stage
