Correlating the end-Triassic mass extinction and flood basalt volcanism at the 100 ka level

New high-precision U/Pb geochronology from volcanic ashes shows that the Triassic-Jurassic boundary and end-Triassic biological crisis from two independent marine stratigraphic sections correlate with the onset of terrestrial flood volcanism in the Central Atlantic Magmatic Province to <150 ka. This narrows the correlation between volcanism and mass extinction by an order of magnitude for any such catastrophe in Earth history. We also show that a concomitant drop and rise in sea level and negative delta C-13 spike in the very latest Triassic occurred locally in <290 ka. Such rapid sea-level fluctuations on a global scale require that global cooling and glaciation were closely associated with the end-Triassic extinction and potentially driven by Central Atlantic Magmatic Province volcanism.

Blood glucose level on postoperative day 1 is predictive of adverse outcomes after cardiovascular surgery.

AIM: Hyperglycaemia is now a recognized predictive factor of morbidity and mortality after coronary artery bypass grafting (CABG). For this reason, we aimed to evaluate the postoperative management of glucose control in patients undergoing cardiovascular surgery, and to assess the impact of glucose levels on in-hospital mortality and morbidity. METHODS: This was a retrospective study investigating the association between postoperative blood glucose and outcomes, including death, post-surgical complications, and length of stay in the intensive care unit (ICU) and in hospital. RESULTS: A total of 642 consecutive patients were enrolled into the study after cardiovascular surgery (CABG, carotid endarterectomy and bypass in the lower limbs). Patients' mean age was 68+/-10 years, and 74% were male. In-hospital mortality was 5% in diabetic patients vs 2% in non-diabetic patients (OR: 1.66, P=0.076). Having blood glucose levels in the upper quartile range (> or =8.8 mmol/L) on postoperative day 1 was independently associated with death (OR: 10.16, P=0.0002), infectious complications (OR: 1.76, P=0.04) and prolonged ICU stay (OR: 3.10, P<0.0001). Patients presenting with three or more hypoglycaemic episodes (<4.1 mmol/L) had increased rates of mortality (OR: 9.08, P<0.0001) and complications (OR: 8.57, P<0.0001). CONCLUSION: Glucose levels greater than 8.8 mmol/L on postoperative day 1 and having three or more hypoglycaemic episodes in the postoperative period were predictive of mortality and morbidity among patients undergoing cardiovascular surgery. This suggests that a multidisciplinary approach may be able to achieve better postoperative blood glucose control.

Analysis of the regulation of Nodal function by SPC-mediated cleavage during early mammalian development

RÉSUMÉ Après implantation dans l'utérus, le foetus de mammifère est composé de trois populations différentes de cellules: l'epiblast, l'ectoderme extraembryonnaire et l'endoderme viscéral. Pendant la gastrulation, les cellules de l'epiblast donnent naissance aux trois lignées germinales: l'ectoderme, le mésoderme et l'endodermes. Les lignées germinales produisent par la suite les différents tissus et organes du corps embryonnaire et adulte. Les cellules de l'ectoderme extraembryonnaire donnent par la suite le composant foetal du placenta qui est essentiel à la survie de l'embryon dans l'utérus. L'épiblast et l'ectoderme extraembryonnaire sont entourés par l'endoderme viscéral et forment une structure connue sous le nom de bouton embryonnaire. L'endoderme viscéral joue un rôle important dans l'embryogenèse car il comporte une sous-population de cellules appelées l'endoderme viscéral antérieur dont les signaux influencent l'épiblast adjacent et déterminent le futur axe antéro-postérieur de l'embryon. La protéine de signalisation Nodal de la famille des TGFß est essentielle dans l'épiblast pour spécifier le mésendoderme, l'endoderme viscéral antérieur, ainsi que pour maintenir les cellules souche de l'ectoderme extraembryonnaire. Ainsi, dans les embryons mutants pour Nodal, aucun axe antéro-postérieur n'est établi, les lignées germinales ne sont pas spécifiés et le placenta ne se développe pas. Au niveau moléculaire, comme pour les protéines de la famille des TGFß, Nodal est initialement synthétisée sous forme de précurseur avant d'être clivée de façon endoproteolytique par des protéanes sécrétées, les proprotéines convertases du type subtilisin (SPC), qui suppriment la partie inhibitrice N-terminale du pro peptide. Dans ce contexte, le projet de ma thèse a été d'analyser l'influence des SPC sur la fonction de Nodal en employant une combinaison d'approches génétiques et biochimiques. Premièrement, nous avons constaté que le clivage du précurseur par les protéases active Nodal, mais en même temps augmente son turn-over et diminue la portée de son action. Deuxièmement, dans l'embryon, il apparaît que Nodal est activé par l'action combinée de Furin et de PACE4, deux protéases sécrétées qui sont spécifiquement exprimées dans les cellules de l'ectoderme extraembryonnaire, donc adjacentes au domaine d'expression de Nodal. De manière similaire aux mutants de Nodal, les embryons mutants pour les deux protéases ne forment pas d'endoderme viscéral antérieur et ne gastrulent pas. Cependant, certains gènes cible de Nodal restent exprimés, suggérant que toutes les activités de Nodal ne sont pas dépendent du clivage par les SPCs. En effet, la génération et l'analyse de mutants portant un allèle knock-in qui code pour une forme mutante de Nodal résistante aux SPC, ont montré que ces mutants ont les caractères phénotypique des mutants de Nodal seulement de façon partielle. La formation de mésoderme est partiellement induite, et de façon remarquable, la forme de Nodal résistante aux SPC est capable d'agir à une distance de sa source, maintenant l'expression de ses propres protéases et d'autres gènes essentiels pour la spécification de l'ectoderme extraembryonnaire. Ensemble, ces résultats prouvent que par leur action directe les protéases extraembryonnaire modulent la signalisation de Nodal pendant le développement mammifère précoce. SUMMARY : Early after implantation in the uterus, the mammalian conceptus is composed of three different cell populations: the epiblast, the extraembryonic ectoderm and the visceral endoderm. During gastrulation, epiblast cells give rise to the three embryonic germ layers: the ectoderm, the mesoderm and the endoderm. These germ layers then generate the different tissues and organs of the embryonic and adult bodies. In parallel, extraembryonic ectoderm cells give rise to the fetal component of the placenta, which is essential for the survival of the embryo in the uterus. Both the epiblast and extraembryonic ectoderm are surrounded by the visceral endoderm to form a structure known as the egg cylinder. The visceral endoderm plays an important role as it harbours a subpopulation of cells called the anterior visceral endoderm, from which signals influence the adjacent epiblast and determine the future antero-posterior embryonic axis. The TGFß-related signalling protein Nodal is required within the epiblast to specify the mesoderm, the endoderm,the anterior visceral endoderm and is also essential to maintain stem cells in the extraembryonic ectoderm. Thus, in Nodal null conceptuses, no antero-posterior axis is established, the germ layers are not specified and the placenta does not develop. At the molecular level, Nodal, like related proteins of the TGFß family, is initially synthesized as a precursor and undergoes endoproteolytic cleavage by secreted proteases of the subtilisin-like proprotein convertases (SPC) to remove an inhibitory N-terminal pro peptide. In the embryo, Nodal is activated by the combined action of Furin and PACE4, two secreted SPCs that are specifically expressed in cells of the extraembryonic ectoderm, thus adjacent to the Nodal expression domain. Similar to Nodal null .embryos, mutant embryos lacking both these proteases fail to specify the anterior visceral endoderm and to undergo gastrulation. However, these mutants still express a subset of Nodal target genes, suggesting that part of Nodal activity is independent on cleavage by SPCs. Indeed, by generating and analyzing mutants with a knock-in allele that encodes an SPC-resistant mutant form of Nodal, I could show that they retain a subset of Nodal activities. Mesoderm formation is partially induced, but most remarkably, SPC-resistant Nodal form is able to act at a distance from its source, maintaining the expression of its proteases and of other genes essential for maintenance of the extraembryonic ectoderm.

Uncertainty about the true source. A note on the likelihood ratio at the activity level.

This paper focuses on likelihood ratio based evaluations of fibre evidence in cases in which there is uncertainty about whether or not the reference item available for analysis - that is, an item typically taken from the suspect or seized at his home - is the item actually worn at the time of the offence. A likelihood ratio approach is proposed that, for situations in which certain categorical assumptions can be made about additionally introduced parameters, converges to formula described in existing literature. The properties of the proposed likelihood ratio approach are analysed through sensitivity analyses and discussed with respect to possible argumentative implications that arise in practice.

Addressing High Level ICT Skills Recruitment Needs

Ireland is a successful major centre for ICT operations with ten of the top ICT companies in the world having substantial operations here. The large talent pool of ICT professionals that exists here is valuable both for foreign-owned and Irish companies. The cluster of internationally renowned firms and Irish companies offer a range of attractive career opportunities for professionals. A range of skills recruitment difficulties have been raised through the work of the Expert Group on Future Skills Needs (EGFSN), specifically the immediate issue of high-level ICT skills within both the ICT sector and from other sectors such as international financial services, banking and business services. Forfs, with the support of IDA Ireland and Enterprise Ireland, engaged in discussions with a selected range of foreign–owned and Irish companies employing approximately 30,000 employees to establish the nature of positions involved, the reasons for recruitment difficulties and to identify measures to help address them. Consultations were also held with key stakeholders including IDA Ireland, Enterprise Ireland, ICT Ireland, Software Ireland, IT@Cork, Engineers Ireland and Dublin Chambers of Commerce. Discussions were held with the heads of the computing departments of all Universities and Institutes of Technology at a meeting chaired by the Higher Education Authority. An in-depth analysis of third-level ICT supply statistics and trends was undertaken to inform the research.

Do brief alcohol motivational interventions work like we think they do?

BACKGROUND: Questions remain about how brief motivational interventions (BMIs) for unhealthy alcohol use work, and addressing these questions may be important for improving their efficacy. Therefore, we assessed the effects of various characteristics of BMIs on drinking outcomes across 3 randomized controlled trials (RCTs). METHODS: Audio recordings of 314 BMIs were coded. We used the global rating scales of the Motivational Interviewing Skills Code (MISC) 2.1: counselor's acceptance, empathy, and motivational interviewing (MI) spirit, and patient's self-exploration were rated. MI proficiency was defined as counselor's rating scale scores ≥5. We also used the structure, confrontation, and advice subscale scores of the Therapy Process Rating Scale and the Working Alliance Inventory. We examined these process characteristics in interventions across 1 U.S. RCT of middle-aged medical inpatients with unhealthy alcohol use (n = 124) and 2 Swiss RCTs of young men with binge drinking in a nonclinical setting: Swiss-one (n = 62) and Swiss-two (n = 128). We assessed the associations between these characteristics and drinks/d reported by participants 3 to 6 months after study entry. RESULTS: In all 3 RCTs, mean MISC counselor's rating scales scores were consistent with MI proficiency. In overdispersed Poisson regression models, most BMI characteristics were not significantly associated with drinks/d in follow-up. In the U.S. RCT, confrontation and self-exploration were associated with more drinking. Giving advice was significantly associated with less drinking in the Swiss-one RCT. Contrary to expectations, MI spirit was not consistently associated with drinking across studies. CONCLUSIONS: Across different populations and settings, intervention characteristics viewed as central to efficacious BMIs were neither robust nor consistent predictors of drinking outcome. Although there may be alternative reasons why the level of MI processes was not predictive of outcomes in these studies (limited variability in scores), efforts to understand what makes BMIs efficacious may require attention to factors beyond intervention process characteristics typically examined.

ICT Action Plan Meeting the high-level skills needs of enterprise in Ireland

The technology sector in Ireland is thriving. Employment, through indigenous and multinational technology firms continues to grow strongly year on year. All of the top 10 multinational technology companies have a significant presence in Ireland and the indigenous software sector’s exports are worth well in excess of €1 billion annually. Five of the top 10 exporters in Ireland are technology companies, and the sector is responsible for approximately one-third of Ireland’s total turnover. Since January 2011, over 80 jobs a week have been announced in the sector. This is on foot of 6% employment growth in 2009 and 4% in 2010. A recent global competitiveness report ranks Ireland as the top destination in the world by quality and value of investments. With a growing multinational technology presence in Ireland and a vibrant and innovative indigenous software sector, the future prospects for Ireland’s technology sector are bright.

Naming the Reformed Junior Cycle Proposals for the Minister for Education and Skills - Irish Second Level Students Union (ISSU)

It was important to us to engage with as many students as possible throughout the process of developing a new name for the reformed junior cycle. In this vein, we used a wide variety of methods to engage with students in order to capture as many ideas as possible; text messaging, Facebook, Twitter, email and consultation sessions. We circulated posters to all schools via post and/or email, and contacted schools in catchment areas for the consultation sessions by phone. In our consultation sessions, we had discussions with the participating students about what the new junior cycle would be, closely guided by the content of “Towards a Framework for Junior Cycle” from the National Council for Curriculum and assessment. In these sessions, students then gave feedback on what they thought of the reformed junior cycle, developed their own ideas, and identified what they thought should be reflected in the name of the reformed junior cycle

Review of Ireland's International Education Strategy 2013 - consultation Paper

Investing in Global Relationships: Ireland’s International Education Strategy 2010 – 2015 was published in September 2010. Significant progress has been made in implementing this strategy, to complement and support the work undertaken at institutional level: - A strong national brand is now in place: Education in Ireland, managed by Enterprise Ireland. - There is much closer alignment between education and immigration policies. - A new Government of Ireland Scholarship has been established, managed by the Higher Education Authority. - An International Education Marketing Fund has been developed which allows institutions to collaborate in Enterprise Ireland- led national marketing initiatives. - Promotional efforts are taking place in the priority markets of the USA, Brazil, China, India, SE Asia and the Gulf. Ministers have visited each of the priority markets in the last two years. - Ireland is participating at national level in major international scholarship schemes such as Science Without Borders (Brazil) and the King Abdullah Scholarship Programme (Saudi Arabia). - Statutory provision is now in place for an international education mark and code of practice, which will be rolled out in 2014 by Qualifications and Quality Assurance Ireland (QQI). - International student numbers have risen in priority sectors: 14% growth in the English language sector and 9% growth in higher education since 2010. - Ireland’s international education offering has also diversified, including with increasingly significant levels of cross- border provision. However, global demand for education continues to change rapidly. There continues to be a massive expansion in demand for education around the world, particularly in emerging markets with growing middle classes.
