A study to explore mothers' and fathers' shared and individual experiences of premature birth : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Psychology at Massey University, Albany, New Zealand
This qualitative research project using some of the methodologies of Grounded Theory looked at five couples' experiences of premature birth, in particular comparing and contrasting the experiences of mothers and fathers. Significant themes that were identified were: helplessness, related to parents' belief that they were unable to alter outcomes for their baby; issues of control around the care of the newborn baby; communication and relationships with healthcare staff and the impact on parents' perceptions of inclusiveness in the care of their infants; and for fathers in particular, feeling that they missed out on aspects of the parenting of their newborn. The conclusions were that, due to a number of factors within the NICU environment in conjunction with gender specific methods of coping, fathers tend to be marginalised and excluded from the care of their babies. As a result of this, fathers then distance themselves from contact with their newborns, leading to the cyclic exacerbation of the issues of control and helplessness, which further reinforces their disengagement from the situation. Mothers struggled with the same issues, but not to the extent that they withdrew emotionally and physically from the care of their babies

Many other software products, including operating systems, load parts of themselves from a server across a network. Although users may be confident that their workstation is physically secure, some part of the network to which they are attached almost certainly is not secure. Most proposals that recommend cryptographic means to protect remotely loaded software also eliminate the advantages of remote loading-for example, ease of reconfiguration, upgrade distribution, and maintenance. For this reason, they have largely been abandoned before finding their way into commercial products. The article shows that, contrary to intuition, it is no more difficult to protect a workstation that loads its software across an insecure network than to protect a stand-alone workstation. In contrast to prevailing practice, the authors make essential use of a collision-rich hash function to ensure that an exhaustive off-line search by the opponent will produce not one, but many candidate pass words. This strategy forces the opponent into an open, on-line guessing attack and offers the user a defensive strategy unavailable in the case of an off-line attack.Peer reviewe
Primordial black hole production during preheating in a chaotic inflationary model
In this paper we review the production of primordial black holes (PBHs)
during preheating after a chaotic inflationary model. All relevant equations of
motion are solved numerically in a modified version of HLattice, and we then
calculate the mass variance to determine structure formation during preheating.
It is found that production of PBHs can be a generic result of the model, even
though the results seem to be sensitive to the values of the smoothing scale.
We consider a constraint for overproduction of PBHs that could uncover some
stress between inflation-preheating models and observations.Comment: 6 pages, 5 figures. Prepared for the conference proceedings of the

Currnent and likely future performance of advanced natural ventilation
Advanced natural ventilation (ANV), often characterised by the use of dedicated ventilation stacks, shafts and other architecture features such as atria, light wells, has gained popularity for natural ventilation design in recent decades. In this research, a prototype ANV system is proposed, and the likely thermal performance in a range of UK climatic conditions predicted using dynamic thermal
simulation. The simulations showed that ANV has greater resilience to future climatic conditions in the north of the UK than in the south-east and that, for the assumed internal heat gains, the design studied is unlikely to maintain comfortable conditions in the southeast of England beyond the middle of this century
Engaging with change: Information and communication technology professionals’ perspectives on change at the mid-point in the UK/EU Brexit process
Background
Information and Communication Technology (ICT) has been a key agent of change in the 21st century. Given the role of ICT in changing society, this research explores the responses and attitudes to change over time from ICT professionals and ICT academics in dealing with the potentially far reaching political challenge triggered by the UK’s 2016 European Union Referendum and its decision to leave the European Union (Brexit). Whilst the vote was a UK based decision its ramifications have global implications and as such the research was not confined to the UK. This article presents the second phase of the research at the mid-point in the UK/European Union (EU) Brexit process, thus complementing the findings gathered immediately after the Referendum decision. The fundamental question being researched was: What are ICT professionals’ personal and professional perspectives on the change triggered by Brexit in terms of opportunities and threats?
Methods and findings
Data was collected through a survey launched in March 2018, one year on from the UK’s triggering of Article 50 and marking the mid-point in the two-year Brexit process. The survey replicated the one delivered at the point of the Referendum decision in 2016 with some developments. In addition, two appreciative inquiry focus groups were conducted. The research sought to understand any shifting perspectives on the opportunities and threats that would exist post-Brexit for ICT professionals and academics. 59% of survey participants were negative regarding the Brexit decision. Participants noted the position post-Brexit for the UK, and the remaining 27 EU Member States (EU27), was still very uncertain at this stage. They observed that planned change versus uncertainty provides for very different responses. In spite of the uncertainty, the participants were able to consider and advocate for potential opportunities although these were framed from national perspectives. The opportunities identified within the appreciative inquiry focus groups aligned to those recorded by survey participants with similar themes highlighted. However, the optimum conditions for change have yet to be reached as there is still not an informed position, message and clear leadership with detailed information for the ICT context. Further data will be gathered after the UK exit from the EU, assuming this occurs
NME: rock music media dinosaur or breakthrough act?
When I was a student in the 1980s the New Musical Express was a lifestyle Bible that had earned our respect with its political/punk coverage in the late 70s. Now my thirteen year old devours it with even greater enthusiasm as he practices his indie pop riffs in his skinny black jeans. So has nothing changed as this music media legend celebrates over half a century of charting the charts? Of course, like every other bit of media it is under seige from the Internet and sales of the magazine have fallen. But it is also branching out online with social networking and broadcast plans. My son tells me that he knows that he can find stuff about bands via Myspace or YouTube and that he can watch endless music channels digitally. But he says he likes NME in its magazine form because it is ‘excellent’. He loves the writing and the ritual of its weekly delivery. There’s a lesson there for anyone defending a media brand in the digital age. Polis intern Matt Lomas has been looking at the prospects for the New Musical Express. Here’s his article

En este texto se muestra cómo la desigualdad entre hombres y mujeres (y las diversas formas de violencia asociadas a esa desigualdad) es el efecto del influjo de una serie de factores personales, familiares, educativos y socioculturales que contribuyen tanto a la construcción social de una determinada manera de entender la condición masculina y femenina como en consecuencia a la pervivencia del sexismo en nuestras sociedades.This text shows how the inequality among men and women (and the different forms of violence associated with that inequality) is the effect of the influence of a series of personal, familiar, educational and sociocultural factors. These factors contribute to the social construction of a given way of understanding the masculine and feminine condition and, as a result, to the persistence of sexism in our societies. justify the inequalities among men and women
Examining the issues & challenges of email & e-communications. 2nd Northumbria Witness Seminar Conference, 24-25 Oct 2007 Northumbria University, Newcastle upon Tyne.
These proceedings capture the content of the second Witness Seminar hosted by Northumbria University’s School of Computing, Engineering and Information Sciences. It followed the success of the first witness seminar in terms of its format and style but differed in that it focused on one topic - managing email and other electronic communications technologies from a records perspective. As before the witnesses were invited to share their views and opinions on a specific aspect taking as their starting point a pertinent published article(s). Three seminars explored the business, people and technology perspectives of email and e-communications, asking the following questions: What are the records management implications and challenges of doing business electronically? Are people the problem and the solution? Is technology the problem or panacea? The final seminar, 'Futurewatch', focused on moving forward, exploring new ways of working, potential new technologies and what records professionals and others need to keep on their radar screens
Environmental accounting for ecosystem conservation: Linking societal and ecosystem metabolisms
This paper proposes an approach to environmental accounting useful for
studying the feasibility of socio-economic systems in relation to the external
constraints posed by ecological compatibility. The approach is based on a
multi-scale analysis of the metabolic pattern of ecosystems and societies and
it provides an integrated characterization of the resulting interaction. The
text starts with a theoretical part explaining (i) the implicit epistemological
revolution implied by the notion of ecosystem metabolism and the fund-flow
model developed by Georgescu-Roegen applied to environmental accounting, and
(ii) the potentials of this approach to create indicators to assess ecological
integrity and environmental impacts. This revolution also makes it possible to
carry out a multi-scale integrated assessment of ecosystem and societal
metabolisms at the territorial level. In the second part, two applications of
this approach using an indicator of the negentropic cost show the possibility
to characterize in quantitative and qualitative terms degrees of alteration
(crop cultivation, tree plantations)for different biomes (tropical and boreal
forests). Also, a case study for land use scenarios has been included. The
proposed approach represents an integrated multi-scale tool for the analysis of
nature conservation scenarios and strategies.Comment: 29 pages including 6 figure
