Parallelisms between sea surface temperature changes in the western tropical Atlantic (Guiana Basin) and high latitude climate signals over the last 140 000 years

Sea surface temperatures (SST) in the Guiana Basin over the last 140 ka were obtained by measuring the C37 alkenone unsaturation index Uk'37 in the sediment core MD03-2616 (7° N, 53° W). The resulting data set is unique in the western tropical Atlantic region for this period. The SSTs range from 25.1 to 28.9 °C, i.e. glacial-interglacial amplitude of 3.8 °C, which is in the range of change of other tropical areas. During the last two interglacial stages (marine isotope stages; MIS1 and MIS5e) and warm long interstadials (MIS5d-a), a rapid transmission of climate variability from Arctic-tropical latitudes is recorded. During these periods, the MD03-2616 SSTs show a conspicuous parallelism with temperature changes observed in Greenland and SST records of North Atlantic mid-latitude cores (Iberian Margin 38° N, Martrat et al., 2007). The last deglaciation in the Guiana Basin is particularly revealing. MIS2 stands out as the coldest period of the interval analysed. The events recorded in Guiana parallel northern latitude events such as the Bølling-Allerød warming and the Younger Dryas cooling which ensued. These oscillations were previously documented in the δ18O of the Sajama tropical ice core (Bolivia) and are present in Guiana, with rates of ca. 6 °C ka-1 and changes of over 2 °C. During the glacial interval, significant abrupt variability is observed, e.g. oscillations of 0.5-1.2 °C during MIS3, which is about 30 % of the maximum glacial-interglacial SST change. In the MD03-2616 record, it is possible to unambiguously identify either the Dansgaard-Oeschger oscillations described in northern latitudes or the SST drops associated with the Heinrich events characteristic of North Atlantic records. Although these events form the background of the climate variability observed, what truly shapes SSTs in the Guiana Basin is a long-term tropical response to precessional changes, which is modulated in the opposite way to Northern Hemisphere variability. This lack of synchrony is consistent with other tropical records in locations to the north or south of the Guiana Basin and evidences an Arctic-tropical decoupling when a substantial reduction in the Atlantic meridional overturning circulation (AMOC) takes place. © Author(s) 2015.

Careers leadership in practice: a study of 27 careers leaders in English secondary schools

Historically, responsibility for career education and guidance in English schools was shared between the school and an external careers service. The Education Act 2011 transferred responsibility for career guidance to schools. Andrews and Hooley (2017) argued that for schools to successfully manage these new arrangements they require a ‘careers leader’. In this article, we report on research in 27 English state schools and multi-academy trusts where careers leadership currently exists. This research broadly endorses Andrews and Hooley’s typology of careers leadership tasks with the addition of a new task around securing funding. However, it is noted that the way in which these tasks are organised varies, with five models of careers leadership evident. The advantages and potential challenges of each model are outlined and implications for the training and professional development of careers leaders are discussed.The Careers & Enterprise Compan

Design Education in Tanzania; Design Skills & Marketing Capabilities for a Developing Economy

A Least Developed Country, 40% of Tanzania is dependent on cotton and its production and products. Presentation will demonstrate how the development of fashion and textile design education in Tanzania links into the various economic policies and institutions committed to helping poverty alleviation and spur the process of industrialisation to the level of the Asian Tiger economies. Policy implications will be presented to maximise the potential value of design education. In 2005/6, cotton production & processing was the largest agricultural export earner, representing potentially significant contribution to poverty alleviation and socio-economics. I was in a team of nine conducting research into this industry (from seed to design & marketing) funded and co-ordinated by the Tanzania Gatsby Trust (TGT - part of the Gatsby Charitable Foundation) in Dar es Salaam (Dar). My background is fashion design, my PhD examined design/marketing in the fashion design process and I am a lecturer in fashion management at the University of Manchester (UoM). My project task: review current design/marketing capabilities in the fashion/textiles (f/t) sector, recommend methods to help further develop capabilities in the small scale craft (informal) and larger (formal) sectors and identify ways of linking international/national and local designers with a view to encouraging foreign trade investment (FDI). From my research: SME’s were keen to upgrade their design skills; larger companies less so - many invested in CAD but only for communicating, negotiating and speeding up manufacturing process, working to buyers’ specifications, or amending past successes (thus susceptible to competition from lower cost manufacturers); they recruited designers from overseas, none provided training in design. Dar’s burgeoning business & professional community is enthusiastic about arts, culture and f/t; magazines, tv and internet sites cover news, trends and nationally recognised fashion designers; some non f/t businesses use the promotional powers of the fashion show. Drama and Fine Art education are established through institutes such as Taasisi ya Sanaa na Utamaduni Bagamoyo (Tasuba) and the University of Dar es Salaam (UDSM). There is no formal education for f/t design and this limits creative thinking and analysis of many issues, especially anticipating future trends. A framework for establishing design education to degree level in Dar builds upon a system already in place with national implications; it has been adopted by the Vocational and Educational Training Authority (VETA). A government body, VETA has 22 vocational training centres distributed in 20 (of 21) mainland political regions, coordinating over 860 vocational training centres and over 90 courses to vocational level, including tailoring, basic factory production techniques and textile design skills. Foundation/degree level design training requires creative brief setting/assessing. TGT is funding: (i) VETA trainers to visit UoM to learn about creative briefs (ii) UDSM graduates to undertake MSc studies in textiles (technology and design) at UoM to help re-establish the hitherto abandoned textiles department at UDSM, (iii) VETA to develop a BA in fashion/textiles with the UDSM (VETA have already done a similar exercise with Tourism and Hospitality). Establishing design education through VETA will create networks at local, national and international levels, MoU’s, research, studentships, etc. Individuals will be enabled to engage in a global community, knowledge and know-how exchange, raising creativity and providing a platform on which to invite international buyers and experts. Attracting FDI is a key feature of successful creative industries in developing nations. Tanzanian f/t sector is largely unable to do so (through uncompetitive skills & production rates in manufacture, lack of access to internationally acceptable quality fabrics, inappropriate styling and quality control). These difficulties are compounded by, among others, the informal nature of the sector, which the government is working to alleviate through initiatives supporting and integrating the (large) informal economy into the mainstream formal. To help maximise the value of design education, a policy message is to focus on reach and quality of secondary level education – normally a prerequisite for foundation/degree - to raise the quality of potential foundation and degree program entrants

Design Capabilities and Potential in “The Cotton and Textiles Sector in Tanzania: Issues and Opportunities. A report for the Tanzanian Government”

This study originates from discussions between Hon Juma Ngasongwa, Minister of Planning, Economy and Empowerment and Hon Basil Mramba, Minister for Trade and Industry and Lord David Sainsbury, settlor of the Gatsby Charitable Foundation (GCF) in January 2007. In discussions held in Dar es Salaam, iIt was agreed that GCF and its associated Trust, the Tanzania Gatsby Trust (TGT), would fund an exploratory study of the cotton and textile sectors with a view to identifying issues, constraints and investment opportunities. The focus of the study would be on the long-term potential for a major increase in the output of Tanzania’s cotton and textile sector with a view to maximising its potential contribution to the generation of increased GDP, exports, farmer incomes and manufacturing employment. Terms of Reference were finalised in February. And the study is essentially a contribution to the development of strategy in the context of the ‘Mini Tiger Plan’. This report represents the findings of a team comprising consultants from Golder Associates of South Africa, the University of Manchester in the UK and Oxford Policy Management. The individuals concerned were : Golder Associates : Bill Berry, John Howcroft, Julian Ward, René Ford University of Manchester (Materials and Paper Dept) : Drs Hugh Gong, Richard Kennon, Neil Towers, Pammi Sinha, Mr. Les Downes and Mr Alan Johnson Oxford Policy Management : Tim Ruffer The study was co-directed by Ibrahim Seushi and Laurence Cockcroft on behalf of GCF and TGT. Organisational arrangements were carried out by TGT under the leadership of Mrs Olive Luena. TGT in cooperation with the Ministry of Trade and Industry arranged many on-site visits for which the consultancy team is very grateful. The majority of these are listed in an Annexe to this report and the team is likewise extremely appreciative of the time and interest shown by the many individuals who participated in interviews and meetings. It was particularly helpful to have two stakeholder meetings with cotton growers, ginnery owners and farmers in both Mwanza and Morogoro and the team is very grateful to the Tanzania Cotton Board and representatives of Regional Governments for arranging and participating in these meetings. The Main Report of the study synthesises five technical reports which will be presented as Annexes to this report (see Table of Contents). It is intended to comprise a basis for discussion which will lead to an Action Plan for the sector to be further developed through a Stakeholders Forum to be held later in 2007

Healing Through Art An Examination of the Intersection of the Queer and Disabled Communities

Individuals identifying as both ‘queer’ and ‘disabled’ are presented with unique challenges when interacting with support systems of family, community, institutions, and biomedicine. For queer-disabled people, the act of seeking care within these systems does not necessarily result in healing and can often lead to increased trauma, often necessitating alternative healing options. Queer-disabled people use art as one such holistic healing modality in various ways, including through art therapy, individual art practice, and as a tool for community building and social justice. The artistic expression channeled by the queer-disabled community is an effective site of resistance that promotes visibility and has the power to affect change. My research explores how interaction within support systems drives queer-disabled individuals to utilize art as a form of healing and resistance. I examined the impact of community-based art projects in comparison to art therapy and art practice, conducted ethnographic interviews and participant observation where I created a community-based art project with a cohort of my queer-disabled peers. My research shows how the experience of using art as a healing modality empowers the queer-disabled community on an individual and group level. My research results provide a strong foundation for my further study of the queer-disabled community and the challenges faced when seeking care in the biomedical system while taking a deeper look into the complexities of engagement with the arts for healing

Paleoceanografía de los sectores tropicales en los océanos Pacífico oriental y Atlántico occidental durante los últimos ciclos climáticos

[ES]Esta Tesis Doctoral está enfocada al estudio de la variabilidad temporal y espacial de la señal de paleoproductividad y la topografía de la nutri-termoclina durante los últimos ciclos climáticos en los océanos Pacífico oriental y Atlántico occidental tropicales. Los mecanismos hidrológicos y atmosféricos que controlan estas señales están relacionados con la activación de las células de surgencia, la dinámica de las corrientes superficiales y subsuperficiales, la migración del frente ecuatorial y el desplazamiento latitudinal de la zona de convergencia intertropical ( Intertropical Convergence Zone ITCZ).En este estudio se analizó cuantitativamente la distribución temporal y espacial de las asociaciones de cocolitóforos y del carbonato asociado a estos organismos en las secuencias sedimentarias 1240 (estadios 15 a 1), 1241 (estadios 20 a 1) y 1242 (estadios 22 a 1), extraídas por el proyecto Ocean Drilling Program (ODP) 202 en el océano Pacífico oriental tropical. Adicionalmente se analizó la secuencia MD03-2616 (estadios 6 a 1) recuperada en la campaña PICASSO Cruise en el océano Atlántico occidental tropical. En términos generales, los sedimentos están compuestos principalmente por arcillas hemipelágicas con cantidades variables de nanofósiles calcáreos, foraminíferos, diatomeas y terrígenos, si bien los nanofósiles calcáreos son habitualmente el componente biogénico principal (Mix et al., 2003). Aunque algunos intervalos se caracterizan por una preservación deteriorada en los testigos 1242 y MD03-2616, tratando de enmascarando un poco el significado micropaleontológico de los perfiles de paleoproductividad y del carbonato derivado de los cocolitos, la preservación general de los ejemplares estudiados es buena a moderada, y realza el significado micropaleontológico de estos registros en todos los testigos estudiados.This PhD Thesis is focused on the study of the temporal and spatial variability of the paleoproductivity record, the nutri-thermocline topography and all the mechanisms associated to them in the Eastern Tropical Pacific (ETP) and the Western Tropical Atlantic (WTA) over the lastclimatic cycles. These mechanisms are related to the strengthening of the upwelling cells, the dynamic of the surface and subsurface currents, the migration of the Equatorial Front and the latitudinal displacement of the Intertropical Convergence Zone (ITCZ). The purpose was carried out through the analysis of the calcareous nannoplankton assemblage along the sedimentary sequences from the Ocean Drilling Program (ODP) Leg 202, sites 1240 (Marine Isotope Events MIS 15 to 1), 1241 (MIS 20 to 1) and 1242 (MIS 22 to 1) recovered from the ETP. The calcareous nannoplankton assemblage from core MD03-2616 was also studied for paleoceanographical purposes along MIS 6 to 1. This last sequence was recovered by the PICASSO Cruise in the WTA. Sediments mostly consist of hemipelagic clays with variable amounts of calcareous nannofossils, foraminifers, diatoms and terrigenous matter, being the calcareous nannofossils the primary biogenic component (Mix et al., 2003). Although several intervals are characterized bydeteriorated carbonate preservation at sites 1242 and MD03-2616, masking the micropaleontological signal, the overall preservational pattern varies between good and moderate, enhancing the micropaleontological significance of all the records studied
