Asymmetric diffusion : World Bank 'best practice' and the spread of arbitration in national investment laws
Globally, 74 countries have domestic investment laws that mention investor-state arbitration and 42 of these laws provide consent to it. That is, they give foreign investors the right to bypass national courts and bring claims directly to arbitration. What explains this variation, and why do any governments include investor-state arbitration in domestic legislation? We argue that governments incorporate arbitration into their domestic laws because doing so was labelled ‘international best practice’ by specialist units at the World Bank. We introduce the concept of asymmetric diffusion, which occurs when a policy is framed as international best practice but only recommended to a subset of states. No developed state consents to arbitration in their domestic law, nor does the World Bank recommend that they do so. Yet we show that governments who receive technical assistance from the World Bank’s Foreign Investment Advisory Service are more likely to include arbitration in their laws. We first use event history analysis and find that receiving World Bank technical assistance is an exceptionally strong predictor of domestic investment laws with arbitration. Then we illustrate our argument with a case study of the Kyrgyz Republic’s 2003 law.PostprintPeer reviewe
Surgical treatment for different forms of hernias in sheep and goats
Sheep and goats are frequently presented with different forms of hernias to veterinary clinics. The aim of this study is to investigate the outcome of the surgical treatment of abdominal, umbilical, inguinal and scrotal hernias in sheep and goats. Fifty-eight clinical cases (sheep = 44, goat = 14) were presented to the Veterinary Teaching Hospital, College of Agriculture and Veterinary Medicine, Qassim University, Saudi Arabia from September, 2003 to September, 2006. These animals had abdominal (sheep = 30, goat = 10), umbilical (sheep = 6, goat = 4), inguinal (sheep = 7) and scrotal (sheep = 1) hernias. All the cases of hernias in sheep and goats were subjected to full study including the history of the case, classification of hernias, the size of the hernial ring, surgical repair of the hernias, adhesions between the hernial sacs in each case, the postoperative care and follow up of the cases. The results revealed that gender had an effect on the incidence of hernia. The incidence of abdominal hernias was higher in females and the incidence of inguinal hernia was higher in males. There was a positive correlation between the history of hernia and the degree of adhesion. For the sheep, 26 out of 30 cases of abdominal hernia had good outcomes and the healing was excellent. There were postoperative complications in 4 ewes. For the goats, there were slight swellings at the site of operation in 2 out of 10 cases of abdominal hernia, while the remaining 8 cases had good outcomes. There was one case of umbilical hernia with an umbilical abscess that had broken down with sepsis formation at the surgical site. In conclusion, the success rates of surgical treatment for all types of hernias were very high and there were no significant differences in the success rates among the different types of hernias in both sheep and goats. The types of suture materials and the types of hernias had no significant effect on the outcome of the surgical treatment

Development of a parental feeding goal measure: the family mealtime goals questionnaire
It is well established that parents’ feeding practices predict children’s eating behaviors. However, there has been little research into parents’ mealtime goals – their desired outcomes for family mealtimes. These goals, and potential conflicts between them, may be important both in explaining parents’ feeding practices and improving children’s eating behaviors, as health behavior change is more likely to be achieved by programmes and interventions that are aligned with an individual’s goals.
The objectives of this study were to develop a reliable and valid measure that captures parental mealtime goals, and to describe parents’ endorsement of these goals. Online questionnaire methods were used to design and test the Family Mealtime Goals Questionnaire with 1,140 parents and carers of at least one child aged from 1 to 16 years. Exploratory qualitative analysis, Principal Components Analysis, Confirmatory Factor Analysis and test-retest analysis (using intraclass correlations) were conducted to establish the psychometric properties of the instrument.
An 18-item questionnaire was produced with seven dimensions: stress/conflict avoidance, homemade food, shared family food, family involvement in mealtimes, price, occasional treats, and high/low fat regulation. Some differences were found in the goal structure of parents of children of different ages but stress/conflict avoidance was the most strongly endorsed mealtime goal for all age groups.
The Family Mealtime Goals Questionnaire provides a useful measure of parents’ feeding motivations. It will facilitate large-scale research into the relationships between parents' feeding goals and practices and could inform the design of more effective healthy eating interventions that target specific feeding goals
Long-term benefits of omalizumab in a patient with severe non-allergic asthma
<p>Abstract</p> <p>Introduction</p> <p>Currently, omalizumab is indicated for the treatment of patients with severe allergic uncontrolled asthma despite optimal therapy.</p> <p>Case presentation</p> <p>We studied a 52-year-old man who has been suffering from severe non allergic steroid-resistant asthma with increased levels of total IgE and a lot of comorbidity. After a 3 years long treatment with omalizumab, he presented a significant improvement in disease control in terms of hospitalizations, exacerbation, quality of life and lung function with good safety profile.</p> <p>Conclusion</p> <p>Our case shows, after a long follow-up, how omalizumab can be effective in a severe form of non-atopic asthma. It is therefore hoped that further studies can identify indicators that are able to give to clinicians information about patients who can be responsive to monoclonal anti-IgE antibody even if non allergic.</p
Double Diffraction Dissociation at the Fermilab Tevatron Collider
We present results from a measurement of double diffraction dissociation in
collisions at the Fermilab Tevatron collider. The production cross
section for events with a central pseudorapidity gap of width
(overlapping ) is found to be [] at [630]
GeV. Our results are compared with previous measurements and with predictions
based on Regge theory and factorization.Comment: 10 pages, 4 figures, using RevTeX. Submitted to Physical Review

Search for Narrow Diphoton Resonances and for gamma-gamma+W/Z Signatures in p\bar p Collisions at sqrt(s)=1.8 TeV
We present results of searches for diphoton resonances produced both
inclusively and also in association with a vector boson (W or Z) using 100
pb^{-1} of p\bar p collisions using the CDF detector. We set upper limits on
the product of cross section times branching ratio for both p\bar
p\to\gamma\gamma + X and p\bar p\to\gamma\gamma + W/Z. Comparing the inclusive
production to the expectations from heavy sgoldstinos we derive limits on the
supersymmetry-breaking scale sqrt{F} in the TeV range, depending on the
sgoldstino mass and the choice of other parameters. Also, using a NLO
prediction for the associated production of a Higgs boson with a W or Z boson,
we set an upper limit on the branching ratio for H\to\gamma\gamma. Finally, we
set a lower limit on the mass of a `bosophilic' Higgs boson (e.g. one which
couples only to \gamma, W, and Z$ bosons with standard model couplings) of 82
GeV/c^2 at 95% confidence level.Comment: 30 pages, 11 figure
Search for Gluinos and Scalar Quarks in Collisions at TeV using the Missing Energy plus Multijets Signature
We have performed a search for gluinos (\gls) and squarks (\sq) in a data
sample of 84 pb of \ppb collisions at = 1.8 TeV, recorded by
the Collider Detector at Fermilab, by investigating the final state of large
missing transverse energy and 3 or more jets, a characteristic signature in
R-parity-conserving supersymmetric models. The analysis has been performed
`blind', in that the inspection of the signal region is made only after the
predictions from Standard Model backgrounds have been calculated. Comparing the
data with predictions of constrained supersymmetric models, we exclude gluino
masses below 195 \gev (95% C.L.), independent of the squark mass. For the case
\msq \approx \mgls, gluino masses below 300 \gev are excluded.Comment: 7 pages, 3 figure
Search for the Supersymmetric Partner of the Top-Quark in Collisions at
We report on a search for the supersymmetric partner of the top quark (stop)
produced in events using of
collisions at recorded with the Collider Detector at
Fermilab. In the case of a light stop squark, the decay of the top quark into
stop plus the lightest supersymmetric particle (LSP) could have a significant
branching ratio. The observed events are consistent with Standard Model production and decay. Hence, we set limits on the branching ratio of
the top quark decaying into stop plus LSP, excluding branching ratios above 45%
for a LSP mass up to 40 {\rm GeV/c}.Comment: 11 pages, 4 figure
Measurement of the Strong Coupling Constant from Inclusive Jet Production at the Tevatron Collider
We report a measurement of the strong coupling constant, ,
extracted from inclusive jet production in collisions at
1800 GeV. The QCD prediction for the evolution of with
jet transverse energy is tested over the range 40<<450 GeV using
for the renormalization scale. The data show good agreement with QCD in
the region below 250 GeV. In the text we discuss the data-theory comparison in
the region from 250 to 450 GeV. The value of at the mass of the
boson averaged over the range 40<<250 GeV is found to be
. The associated theoretical uncertainties are mainly due to the choice
of renormalization scale (^{+6%}_{-4%}) and input parton distribution
functions (5%).Comment: 7 pages, 3 figures, using RevTeX. Submitted to Physical Review
