Dinoflagellate cyst-based reconstructions of mid to late Holocene winter sea-surface temperature and productivity from an anoxic fjord in the NE Pacific Ocean

Published contemporary dinoflagellate distributional data from the NE Pacific margin and estuarine environments (n = 136) were re-analyzed using Canonical Correspondence Analysis (CCA) and partial Canonical Correspondence Analysis (pCCA). These analyses illustrated the dominant controls of winter temperature and productivity on the distribution of dinoflagellate cysts in this region. Dinoflagellate cyst-based predictive models for winter temperature and productivity were developed from the contemporary distributional data using the modern analogue technique and applied to subfossil data from two mid to late Holocene (~5500 calendar years before present–present) cores; TUL99B03 and TUL99B11, collected from Effingham Inlet, a 15 km long anoxic fjord located on the southwest coast of Vancouver Island that directly opens to the Pacific Ocean through Barkley Sound. Sedimentation within these basins largely comprises annually deposited laminated couplets, each made up of a winter deposited terrigenous layer and spring to fall deposited diatomaceous layer. The Effingham Inlet dinoflagellate cyst record provides evidence of a mid-Holocene gradual decline in winter SST, ending with the initiation of neoglacial advances in the region by ~3500 cal BP. A reconstructed Late Holocene increase in winter SST was initiated by a weakening of the California Current, which would have resulted in a warmer central gyre and more El Niño-like conditions.

Construction Disputes in Small to Medium Enterprises in Ireland during Recession: Identification of Critical Factors

Purpose - To identify the critical factors causing construction disputes in Small to Medium Enterprises (SMEs) in Ireland during the recent recession period of 2007 to 2013.
Design/Methodology/Approach - A mixed method approach incorporating a literature review, case studies and questionnaire survey, with results analysed using exploratory (data reduction) factor analysis.
Findings - The results indicate seven core critical factors which result in construction disputes in SMEs in Ireland during a recession: Payment and extras; Physical work conditions; Poor financial/legal practise; Changes to the agreed scope of works; Time overrun; Defects; and Requests for increase in speed of project and long-term defects.
Research Limitations/Implications - With Ireland emerging from the current economic recession and the prevalence of SMEs to the construction sector, it is essential to document the core critical factors of construction disputes which emerge within this particular segment of the built environment.
Practical Implications - To address the adversarial nature of the construction sector and the prevalence of SMEs, it is essential to identify and document the critical factors of construction disputes within this remit. It is envisaged that the results of this research will be acknowledged, and the recommendations adopted, by construction SMEs, particularly within Ireland, as they emerge from the economic recession.
Originality/Value - This paper fulfils a gap in knowledge with the emergence of the economic recession and the identification of critical factors of construction dispute within SMEs in the Irish construction industry.

Consensus of Official Position of IOF/ISCD FRAX Initiatives in Asia-Pacific Region.

The fracture risk assessment tool (FRAX(®)) has been developed for the identification of individuals with high risk of fracture in whom treatment to prevent fractures would be appropriate. FRAX models are not yet available for all countries or ethnicities, but surrogate models can be used within regions with similar fracture risk. The International Society for Clinical Densitometry (ISCD) and International Osteoporosis Foundation (IOF) are nonprofit multidisciplinary international professional organizations. Their visions are to advance the awareness, education, prevention, and treatment of osteoporosis. In November 2010, the IOF/ISCD FRAX initiative was held in Bucharest, bringing together international experts to review and create evidence-based official positions guiding clinicians for the practical use of FRAX. A consensus meeting of the Asia-Pacific (AP) Panel of the ISCD recently reviewed the most current Official Positions of the Joint Official Positions of ISCD and IOF on FRAX in view of the different population characteristics and health standards in the AP regions. The reviewed position statements included not only the key spectrum of positions but also unique concerns in AP regions.

The role of the state in investor-state arbitration

The Role of the State in Investor-State Arbitration is a collection of contributions from lawyers, arbitrators and political scientists on the development of the concept of the “State” in a field that currently presents an increasing number of controversial disputes: Investor-State Arbitration. The book analyzes the limits of the host State as a regulator, studying issues such as attribution and the role of State-Owned Enterprises and sub-State entities; the changing role of the home State in Investor-State disputes, including its direct participation in Investor-State arbitration and State to State dispute settlement; and the overall role that both home and host States can play in the improvement of Investor-State Dispute Settlement.

El Capítulo de Inversiones en el Acuerdo de Asociación Transpacífico:¿Una Posibilidad de Cambio y Convergencia?

Spanish Abstract: El presente trabajo analiza los posibles efectos que generaría en la regulación internacional de la inversión extranjera, el acuerdo de un capítulo de inversiones en el Acuerdo de Asociación Transpacífico (TPP), actualmente en negociaciones, sobre la base de la información disponible a la fecha. El artículo aborda cuatro aspectos que presentan especial importancia dada la divergencia de intereses entre algunos de los Estados negociadores: el ámbito de protección de la inversión extranjera; las normas sobre transparencia de los regímenes de inversión y sus disputas; la irrupción de entidades estatales como inversionistas extranjeros; y la solución de controversias a través del arbitraje inversionista-Estado. El autor concluye que en comparación a la actual fragmentación regulatoria de la que dan cuenta los acuerdos internacionales de inversión suscritos por los países negociadores del TPP, la incorporación de un capítulo de inversiones en ese Acuerdo es una oportunidad para avanzar en la convergencia de la regulación sobre inversión extranjera, tanto en materia de estándares sustantivos de protección de la inversión como en la mejora del arbitraje inversionista-Estado como mecanismo de solución de controversias.

Composition of Fe-Mn minerals from island arcs of the West Pacific

This paper presents materials on the chemical and mineralogical composition of Fe-Mn mineralization in island arcs (Kuril, Nampo, Mariana, New Britain, New Hebrides, and Kermadec) in the western part of the Pacific Ocean. The mineralization was proved to be of hydrothermal and/or hydrogenic genesis. The former is produced by hydrothermal Fe and Mn oxi-hydroxides that cement volcanic-terrigenous material in sediments. Some Fe oxyhydroxides can be derived via the halmyrolysis of volcaniclastic material. Crusts of this stage are characterized by fairly low concentrations of trace and rare elements, and their REE composition is inherited from the volcanic-terrigenous material. The minerals of the Mn oxyhydroxides are todorokite and "Ca-birnessite". The Mn/Fe ratio increases away from the discharge sites of the hydrothermal solutions. The hydrogenic Fe-Mn crusts are characterized by high concentrations of trace and minor elements of both the Mn group (Co, Ni, Tl, and Mo) and the Fe group (REE, Y, and Th). The hydrogenic crusts consist of Fe-vernadite and Mn-feroxyhyte. Some of the hydrothermal crusts originally had a hydrothermal genesis. The first data were obtained on crust B30-72-10 from the Macauley Seamount in the Kermadec island arc, which contained anomalously high concentrations of Co (2587 ppm) and other Mn-related trace elements in the absence of hydrogeneous Fe oxyhydroxides.

Seawater carbonate chemistry and biological processes of Porites panamensis during experiments, 2011

Survival of coral planulae, and the successful settlement and healthy growth of primary polyps are critical for the dispersal of scleractinian corals and hence the recovery of degraded coral reefs. It is therefore important to explore how the warmer and more acidic oceanic conditions predicted for the future could affect these processes. This study used controlled culture to investigate the effects of a 1 °C increase in temperature and a 0.2-0.25 unit decrease in pH on the settlement and survival of planulae and the growth of primary polyps in the Tropical Eastern Pacific coral Porites panamensis. We found that primary polyp growth was reduced only marginally by more acidic seawater but the combined effect of high temperature and lowered pH caused a significant reduction in growth of primary polyps by almost a third. Elevated temperature was found to significantly reduce the amount of zooxanthellae in primary polyps, and when combined with lowered pH resulted in a significant reduction in biomass of primary polyps. However, survival and settlement of planula larvae were unaffected by increased temperature, lowered acidity or the combination of both. These results indicate that in future scenarios of increased temperature and oceanic acidity coral planulae will be able to disperse and settle successfully but primary polyp growth may be hampered. The recovery of reefs may therefore be impeded by global change even if local stressors are curbed and sufficient sources of planulae are available.
