Ideal-quasi-Cauchy sequences
An ideal is a family of subsets of positive integers which
is closed under taking finite unions and subsets of its elements. A sequence
of real numbers is said to be -convergent to a real number , if
for each \; the set belongs
to . We introduce -ward compactness of a subset of , the set
of real numbers, and -ward continuity of a real function in the senses that
a subset of is -ward compact if any sequence of
points in has an -quasi-Cauchy subsequence, and a real function is
-ward continuous if it preserves -quasi-Cauchy sequences where a sequence
is called to be -quasi-Cauchy when is
-convergent to 0. We obtain results related to -ward continuity, -ward
compactness, ward continuity, ward compactness, ordinary compactness, ordinary
continuity, -ward continuity, and slowly oscillating continuity.Comment: 16 pages. arXiv admin note: text overlap with arXiv:1005.494
Kac-Ward formula and its extension to order-disorder correlators through a graph zeta function
A streamlined derivation of the Kac-Ward formula for the planar Ising model's
partition function is presented and applied in relating the kernel of the
Kac-Ward matrices' inverse with the correlation functions of the Ising model's
order-disorder correlation functions. A shortcut for both is facilitated by the
Bowen-Lanford graph zeta function relation. The Kac-Ward relation is also
extended here to produce a family of non planar interactions on
for which the partition function and the order-disorder correlators are
solvable at special values of the coupling parameters/temperature.Comment: An extension of the Kac-Ward determinantal formula beyond planarity
was added (Section 5). To appear in Journal of Statistical Physic

Symmetry Constraints in Inflation, -vacua, and the Three Point Function
The Ward identities for conformal symmetries in single field models of
inflation are studied in more detail in momentum space. For a class of
generalized single field models, where the inflaton action contains arbitrary
powers of the scalar and its first derivative, we find that the Ward identities
are valid. We also study a one-parameter family of vacua, called
-vacua, which preserve conformal invariance in de Sitter space. We find
that the Ward identities, upto contact terms, are met for the three point
function of a scalar field in the probe approximation in these vacua.
Interestingly, the corresponding non-Gaussian term in the wave function does
not satisfy the operator product expansion. For scalar perturbations in
inflation, in the -vacua, we find that the Ward identities are not
satisfied. We argue that this is because the back-reaction on the metric of the
full quantum stress tensor has not been self-consistently incorporated. We also
present a calculation, drawing on techniques from the AdS/CFT correspondence,
for the three point function of scalar perturbations in inflation in the
Bunch-Davies vacuum.Comment: 51 pages, 3 figures, 6 appendices. v3: JHEP version. Minor typos

âItâs a big deal, being given a personâ â a study of the links between infertility and adoption
This study was commissioned and funded by Family Care and undertaken by Jo Ward and Joe Smeeton, both Principal Lecturers at Nottingham Trent University. It comprises a review of the literature relating to the links between adoption and infertility, a survey of the views of adoption from people who have experienced infertility, and 3 qualitative interviews with people who have experienced infertility but not adopted
Palliative Care In Hospital: Perceptions of Care : A thesis presented in partial fulfilment of the requirements for a Master of Science in Psychology at Massey University, Manawatu Campus, New Zealand
In New Zealand, as in many other developed countries, a large number of people die in a hospital setting (Broad, Gott & Boyd, 2013). Based on New Zealandâs growing and aging population, this number is expected to increase (Ministry of Health, 2001). Previous studies have investigated how family members perceive palliative care, but there is still a lack of understanding of how families perceive this care in hospital and in particular in a New Zealand context. This research investigated how family members experienced a patientâs palliative care in a medical ward in a New Zealand hospital.
Seven participants who were next-of-kin/contact person for an individual who had passed away while on a medical ward in a New Zealand hospital three to 12 months prior took part in semi-structured interviews which were analysed using thematic analysis. As a result of the analysis, five themes were identified: Physical environment, interactions with staff, communication regarding palliative care, identifying and accepting death, and care after death.
These results have implications for the way in which palliative care is provided in New Zealand hospitals. Through the consideration of these factors, the experience of next-of-kin/contact people can be improved
