Upholding the convention on the rights of the child: a quandary in cyberspace

Put in place to protect the rights of the child, the Convention on the Rights of the Child is a set of non-negotiable standards. A core principle underpinning the Convention is the child's right to participate fully in social arenas and to access sources of social support without excessive interference. Juxtaposing this is the right of the child to be shielded from harm, abuse and exploitation. Over the past several decades the Internet has emerged as a fast and easily accessible medium for people to connect and communicate. While the Internet provides children with a source of support through chat rooms, online communities and social networking sites, just as equally it can expose vulnerable children to predatory and deviant individuals exacerbating the potential for harm. Upholding the Convention in cyberspace is a challenge. The Internet is not owned or regulated by any governing body and accountability is difficult to enforce. This article discusses some of the difficulties of upholding the Convention online and provides recommendations for policy-makers to protect children as they participate in cyberspace.

Study of the transamidative ring expansion of N--halogenoalkyl--lactams of alkyl chain lengths 2–12 in liquid ammonia and other liquid amines: syntheses of 7-, 8- and 9-membered 1,5-diaza cyclic ketones, including routes to (±)-dihydroperiphylline and (±)-celabenzine

N-(3-Halogenopropyl)-4-phenylazetidin-2-ones undergo amination in liquid ammonia followed by transamidative ring expansion to give the eight-membered 4-phenyl -1,5-diazacyclooctan-2-one in excellent yield. Ring expansion of the amines in liquid ammonia is found to be much more effective than in hydrocarbon solvents. Formation of 7-, 8-, and 9-membered azalactams from the requisite -halogenoalkyl--lactams is an excellent synthetic process, though it is not applicable to 10membered rings. In the cases of rings of 13-, 15- and 17-members, although amination and apparent expansion takes place, the large rings appear not to be stable to ammonia and the final products are acyclic amides. N-[4-Halogenobut-2(Z)-enyl]-4-phenylazetidin-2-one satisfactorily forms a 9-membered (Z)-olefinic azalactam, but the (E)-isomer gives an acyclic amino amide. By using alkyl-substituted -lactam side-chains, C-substituted medium rings can be obtained; the relative instability of N-acyl -lactams to ammonia, however, leads to acylamino amides rather than expanded rings.Employing ethylamine in place of ammonia, it is shown that N-ethylated azalactams are formed satisfactorily, and using allylamine, N-allyl medium rings capable of further elaboration are obtained. The chemistry of these systems is discussed. Using transamidation in liquid ammonia, a short synthesis of the 9-membered spermidine alkaloid (±)-dihydroperiphylline is reported. Synthesis of key intermediates, whose transformation into the 13-membered alkaloids of the celabenzine group has already been effected, has been carried out.X-Ray single-crystal structure determinations for 4-phenyl-1,5-diazacyclononan-2-one, trans-4-phenyl-8-methyl-1,5-diazacyclooctan-2-one and (Z)-4-phenyl-1,5-diazacyclonon-7-en-2-one are reported, and comment is made on certain conformational features.

Research intensity and knowledge transfer activity in UK universities

As the innovation process has become more open and networked, Government policy in the UK has sought to promote both research excellence in the university sector and the translation of this into economic benefit through university–business engagement. However, this policy approach has tended to be applied uniformly with little account for organisational differences within the sector. In this paper we consider if differences between universities in their research performance is reflected in their knowledge transfer activity. Specifically, as universities develop a commercialization agenda are the strategic priorities for knowledge transfer, the organisational supports in place to facilitate knowledge transfer and the scale and scope of knowledge transfer activity different for high research intensive (HRI) and low research intensive (LRI) universities? The findings demonstrate that universities’ approach to knowledge transfer is shaped by institutional and organisational resources, in particular their ethos and research quality, rather than the capability to undertake knowledge transfer through a Technology Transfer Office (TTO). Strategic priorities for knowledge transfer are reflected in activity, in terms of the dominance of specific knowledge transfer channels, the partners with which universities engage and the geography of business engagement.

Size-fitting of Intravaginal Rings for Macaques and in vitro Release Kinetics of Zinc Finger Inhibitors

Background: Small molecule inhibitors of the zinc finger domain (ZFI) in the nucleocapsid protein (NCp7) of HIV-1 are potent inhibitors of HIV and SIV
replication and may have utility as topical products to prevent infection. Furthermore, intravaginal rings (IVRs) were developed as coitally-independent,
sustained release devices which could be used for administration of HIV microbicides. The aims of these studies were to demonstrate that IVRs sized for
macaques are practical and compatible with the current generation of thioester-based NCp7 inhibitors.

Methods: Non-medicated silicone elastomer vaginal rings of various sizes thought to be applicable for macaques were prepared and tested for vaginal fit in Pigtailed and Chinese Rhesus macaques. Macaques were monitored for 8 weeks for mucosal disruption by colposcopy and proinflammatory cytokine markers in cervical vaginal lavages (CVL) using Luminex bead-based technology. Three different ZFIs (compounds 52, 89 and 122, each derived from an N-substituted S-acyl-2-mercaptobenzamide thioester scaffold) were loaded at 50 mg into an optimal matrix-type ring design. In vitro continuous release studies were then conducted over 28 days and analyzed by HPLC. Rate of release was determined by linear regression analysis.

Results: Qualitative evaluation at the time of ring insertion suggested that the 25 mm ring provided optimal fit in both macaque species. All rings remained in
place during the study period (2 to 4 weeks), and the animals did not attempt to remove the rings. No tissue irritation was observed, and no signs of physical
discomfort were noted. Also, no significant induction of cervicovaginal proinflammatory markers was observed during the 8-week period during and following ring insertion. One Pigtailed macaque showed elevated IL-8 levels in the CVL during the period when the ring was in place; however, these levels were comparable to those observed in two control macaques. In vitro release of the ZFIs peaked at day 1 and then continually declined to near steady-state rates between 20-30 mcg/day. The percent release after 14 days was 2.9, 2.0 and 0.9 for ZFI 89, 52 and 122, respectively.

Conclusions: IVRs of 25mm diameter, determined to be the optimal size for macaques, were well tolerated and did not induce inflammation. Release of all ZFI compounds followed t 0.5 kinetics. These findings suggest that efficacy testing in primate models is warranted to fully evaluate the potential to prevent
transmission.

Preparing the ground for marine spatial planning in Ireland

Marine spatial planning (MSP) is advocated as a means of managing human uses of the sea in a manner that is consistent with the maintenance of the ecological goods and services of the marine environment. The adoption of a system of MSP is seen as urgent in the face of ever-increasing demands on marine resources. This is particularly so in Ireland with its extensive seas, belatedly being recognised as a significant development resource. MSP is promoted by the European Commission (EC) in a recent Green Paper to which Member States of the Union, including Ireland, generally have responded positively. Arising from this consultative process, the EC has published the 'Blue Book' that commits support for MSP. It has also issued guidelines for an integrated approach to maritime policy. The recently adopted EU Marine Strategy Framework Directive strengthens the case for implementing MSP as it requires each Member State to develop a strategy for its marine resources. There is evidence that a diverse range of stakeholders at national and local levels in Ireland are positively disposed toward MSP but no practical manifestation of the concept is in place, though some preparatory work is underway to facilitate its likely implementation into the future. © 2010 WIT Press.

Government Laws, Regulations and Policies: Small Fish in a Big Pond

Global development has, in recent years, been shaped by the rise of transnational capital. This has implications for the quality and effectiveness of those national laws, regulations and policies in place to monitor transnational capital, ensure that multi national organisations assume responsibility and hold them accountable should they fail to do so. In balancing these objectives, contrasting issues come to the fore, such as the fear of capital flight; an issue especially profound in small open economies where the balance may tip in the favour of retaining, as opposed to regulating, foreign capital.
This paper can be considered in three parts. First, the paper addresses the shift in global leadership from national governments to multinational corporations (with particular reference to the rise of the Transnational Capitalist Class). This shift will incorporate the connotations of the Third Way. In considering this ideology, it will propose the Third Way as a transition phase to a stage when government is more the “third wheel” than an equal partner in governance structures. Second, the implications of the changing nature of governance on the capacity of nation states to develop effective laws, regulations and policies is discussed which leads on to the third aspect of the paper which identifies the challenges for governments, business and society in reimagining the governance structure pertaining to law, regulation and policy and the need to reconsider existing structures in light of global shifts in power structures.
A new leadership structure, both within the national and international governance system has far reaching implications. Boundary constraints no longer an issue, the potential for equality and global democracy is huge. Instead, a post recessionary world faces new governance challenges in the shape of; legitimacy; accountability and responsibility. Capitalism has invaded government and the primary challenge will be in avoiding the same issues that have dogged our financial markets for the last number of years. The challenge then to laws, regulations and public policy is huge, especially considering that the governments regulating are smaller than those dictating agenda on a global level

Wound and skin team. Impact on pressure ulcer prevalence in chronic care.

1. Decreasing the prevalence of pressure ulcers in a chronic care hospital presents a challenge to care providers. 2. The promotion of staff nurses as educational resources has a positive effect on their participation in a wound and skin care team. 3. When basic prevention practices are not in place, risk factors are less useful indicators to predict the development of pressure ulcers. 4. Educating nurses about pressure ulcer etiology, prevention strategies, and treatments has a positive impact on reducing the number of patients who develop pressure ulcers and the number of pressure ulcers that develop on patients in a chronic care hospital.

Developing tomorrow's leaders-Evidence of global talent management in multinational enterprises

Organizations are becoming relentless in managing and developing their key talent. This is a view, however, largely based on anecdote rather than reliable empirical evidence. Utilizing data from 260 multinational enterprises (MNEs), this paper helps redress this deficit. Specifically, this paper explores the extent to which MNEs engage in global talent management (GTM) and deciphers some of the factors which may explain the use and non-use of GTM practices. In so doing, we find that although a significant number of MNEs have systems and mechanisms in place to strategically identify and develop their talent many more seemingly adopt an ad hoc or haphazard approach. For instance, less than half of all MNEs have both global succession planning and formal management development programs for their high-potentials. Consequently it seems that there is a considerable distance yet to be travelled to arrive at a universal appreciation of the need to strategically manage one's key employees. We find the size of the MNE has a significant effect on GTM system usage-larger MNEs are more likely to undertake GTM. Other significant, positive influences include whether products or services are standardized regionally or globally, and if the MNE has a global human resources policy formation body. Of considerable interest is the finding that MNEs operating in the low-tech/low-cost sectors are significantly more likely to have formal global systems to identify and develop high-potentials. © 2009 Elsevier Inc.

Considering the impact of the 'Right to Bargain' Legislation in Ireland: A Review

Ireland is rare among advanced economies in not having statutory trade union recognition legislation for collective bargaining purposes. The matter has been a source of policy contention over the years with attempts to resolve it encapsulated in the so-called ‘Right to Bargain’ legislation, introduced in 2001. This legislation has sought to circumvent statutory recognition in Ireland by putting in place an alternative mechanism for unions to represent members in non-union firms where collective bargaining is not practiced. This review, based on a mixture of empirical and documentary evidence, demonstrates that this legislation was moderately successful for a short period in generating pay rises, improved employment conditions and better access to procedures for union members in non-unionised firms. Indeed, in some respects, it was a superior institutional mechanism to a statutory recognition regime.

Sediment changes upstream and downstream of the Altnahinch Dam in the River Bush in Northern Ireland: A preliminary study

The River Bush must reach a standard of good ecological potential (GEP) by 2015 due to the requirements of the water framework directive. The role of sediments within a water body is extremely important to all aspects of a river's regime. The aim of this research is to investigate the effects of Altnahinch Dam on sediment distribution in the River Bush (a heavily modified water body) with comparison made against the Glendun River (an unmodified water body). Samples collected from the rivers were analysed by physical (pebble count, sieve analysis) and statistical methods (ANOVA, GRADISTAT). An increase in fine sediments upstream of the dam provides evidence that the dam is impacting sediment distribution. Downstream effects are not shown to be significant. The output of this study also implies similar impacts at other drinking water storage impoundments. This research recommends that a sediment management plan be put in place for Altnahinch Dam and that further studies be carried-out concentrating on fine sediment distribution upstream of the dam. 

Ageing and the immune system: focus on macrophages

A fully functioning immune system is essential in order to maintain good health. However, the immune system deteriorates with advancing age, and this contributes to increased susceptibility to infection, autoimmunity, and cancer in the older population. Progress has been made in identifying age-related defects in the adaptive immune system. In contrast, relatively little research has been carried out on the impact of ageing on the innate immune response. This area requires further research as the innate immune system plays a crucial role in protection against infection and represents a first line of defence. Macrophages are central effector cells of the innate immune system and have many diverse functions. As a result, age-related impairments in macrophage function are likely to have important consequences for the health of the older population. It has been reported that ageing in macrophages impacts on many processes including toll-like receptor signalling, polarisation, phagocytosis, and wound repair. A detailed understanding of the impact of ageing on macrophages is required in order to develop therapeutics that will boost immune responses in the older population.

Conflicts in the Middle East since 1945, (London: Routledge, 2007, Third Edition).

This third edition of Conflicts in the Middle East since 1945 analyzes the nature of conflict in the Middle East, with its racial, ethnic, political, cultural, religious and economic factors. Throughout the book Peter Hinchcliffe and Beverley Milton-Edwards put the main conflicts into their wider context, with thematic debates on issues such as the emergence of radical Islam, the resolution of conflicts, diplomacy and peace-making, and the role of the superpowers.

The book is brought fully up to date with events in the Middle East, covering, for instance, developments in Iraq in 2006 where a democratically elected government is in place but the insurgency show no sign of coming under control. The analysis of the Palestinian/Israeli conflict is also brought up to the present day, to include the election of the Hamas government and the 2006 conflict between Israel and Lebanon’s Hizballah.

Including a newly updated bibliography and maps of the area, this is the perfect introduction for all students wishing to understand the complex situation in the Middle East, in its historical context.

Development and testing of an intermediate temperature glass sealant for use in mixed ionic and electronic conducting membrane reactors

High temperature ceramic membranes have interesting possibilities for application in areas of new and developing technologies such as hydrocarbon combustion with carbon dioxide capture and electrochemical promotion of catalysis (EPOC). However, membrane module sealing remains a significant technical challenge. In this work a borosilicate glass sealant (50SiO₂·25B₂O₃·25Na₂O, mol%) was developed to fit the requirements of sealing an air separation membrane system at intermediate temperatures (300-600 °C). The seal was assessed by testing the leak rates under a range of conditions. The parameters tested included the effect of flowrate on the leak rate, the heating and cooling rates of the reactor and the range of temperatures under which the system could operate. Tests for durability and reliability were also performed. It was found that the most favourable reactor configuration employed a reactor with the ceramic pellet placed underneath the inner chamber alumina tube (inverted configuration), using a quartz wool support to keep the membrane in place prior to sealing. Using this configuration the new glass-based seal was found to be a more suitable sealant than traditional alternatives; it produced lower leak rates at all desirable flowrates, with the potential for rapid heating and cooling and multiple cycling, allowing for prolonged usage. © 2010 Elsevier B.V.

A Conditional Approach for Modelling Patient Re-admissions in Hospital using a mixture of Coxian phase-type distributions incorporating Bayes Theorem

The number of elderly patients requiring hospitalisation in Europe is rising. With a greater proportion of elderly people in the population comes a greater demand for health services and, in particular, hospital care. Thus, with a growing number of elderly patients requiring hospitalisation competing with non-elderly patients for a fixed (and in some cases, decreasing) number of hospital beds, this results in much longer waiting times for patients, often with a less satisfactory hospital experience. However, if a better understanding of the recurring nature of elderly patient movements between the community and hospital can be developed, then it may be possible for alternative provisions of care in the community to be put in place and thus prevent readmission to hospital. The research in this paper aims to model the multiple patient transitions between hospital and community by utilising a mixture of conditional Coxian phase-type distributions that incorporates Bayes' theorem. For the purpose of demonstration, the results of a simulation study are presented and the model is applied to hospital readmission data from the Lombardy region of Italy.
