EDDY PROCESSES OF THE WESTERN ADRIATIC CURRENT NEAR CAPE GARGANO
Abstract Eddy processes of the Western Adriatic Current near Cape Gargano are highly modulated by the wind, growing during calm periods following strong wind events. Both single anticyclones and trains of multiple eddies with a regular spacing are observed. Suppression of a single anticyclone in the lee of the Cape was observed by profiling SEPTR moorings to occur when the horizontal gradient of the thermocline depth was increased by the wind. Eddies also form cyclonic filaments extending offshore. Such a filament was observed through the new technique of seismic oceanography to have downslope tilting isotherms and a long, thin, offshore extension in the bottom boundary layer. Recent measurements from two international collaborative research programs reveal new details of eddy activity and instability of the Western Adriatic Current (WAC) as it rounds Cape Gargano in the central Adriatic Sea. The "Dynamics of the Adriatic in Real-Time" (DART) program was focused on understanding the predictability of this system with observation and modelling from October 2005 through September 2006. These included, among other things, measurements from long-term current moorings, profiling SEPTR moorings, tow-yo CTD profiles, remote sensing, and high-resolution modelling using the U.S. Navy Coastal Ocean Model. Remote sensing and modelling, supported by in situ observations, revealed two distinct cases of WAC eddy activity Although Adriatic wind regimes and Cape topography provide the background setting for eddy formation, frontal instabilities and mixing processes determine many details of eddy structure and evolution.

Descent or Dissent? A future of social work education in the UK post-Brexit
This conceptual paper explores the potential crises arising for social work and social work education following the 2016 ‘Brexit’ referendum in the UK. After exploring the complex political terrain of Brexit voting, the political and moral complications arising, this paper attempts to dispel some of the myths associated with the voter types. Subsequently, the uncertain and possibly dangerous futures of social care and welfare are examined before moving to consider the implications for social work education in the UK, as part of the European Union, and beyond. The need for the UK to continue to pursue its relationships and links with other EU colleagues if social work is not to become parochial and somewhat removed from the international stage is highlighted
Hiding Relations
The present vogue of ‘managing for development results’ is an expression of a historically dominant mode of thought in international aid – ‘substantialism’ – which sees the world primarily in terms of ‘entities’ such as ‘poverty’, ‘basic needs’, ‘rights’, ‘women’, or ‘results’. Another important mode of thought, ‘relationalism’ – in association more generally with ideas of process and complexity – appears to be absent in the thinking of aid institutions. Drawing on my own experiences of working with the UK Department for International Development (DFID), I illustrate how despite formally subscribing to the institution’s substantialist view of the world, some staff are ‘closet relationists’, behaving according to one mode of thought while officially framing their action in terms of the other, more orthodox mode. In so doing, they may be unwittingly keeping international aid sufficiently viable - by the apparent proof of the efficacy of results-based management - to enable the institution as a whole to maintain its substantialist imaginary

Applying critical systems thinking to social prescribing: a relational model of stakeholder “buy-in”
Background
Social prescribing (SP) allows health professionals to refer primary care patients toward health and wellbeing interventions and activities in the local community. Now widely implemented across the UK and adopted in other nations, questions arise concerning the modelling of present and future schemes, including challenges to full engagement encountered by stakeholders, which lie beyond the scope of traditional evaluations. Critical Systems Thinking (CST) allows for holistic analysis of fields where multiple stakeholders hold diverse interests and unequal power.
Methods
We use CST to (a) critically examine a developing rural social prescribing scheme from multiple stakeholder perspectives and (b) present a relational model for local social prescribing schemes. Our fieldwork included 24 in-depth interviews, regular planning meetings with key stakeholders, and discussions with those involved with national and international SP landscaping. A modified grounded theory approach was used for the analysis, and to consider the core elements of social prescribing sustainability.
Results
Our study confirms that local social prescribing schemes must operate with numerous stakeholder interests in mind, seeking to address real life social complexity and offer integrated solutions to multifaceted issues. Three main areas are discussed: holistic vision and boundary judgments; barriers and facilitators; relational issues and “emotional buy in”. Problems for staff include selecting suitable clients, feedback and technological issues and funding and evaluation pressures. Barriers for clients include health, transport and expense issues, also lack of prior information and GP involvement. Emotional “buy-in” emerged as essential for all stakeholders, but hard to sustain. Based on our findings we propose a positive relational model comprising shared vision, confidence and commitment; motivation and encouragement, support and wellbeing focus, collaborative relationships, communication and feedback, access to information /resources, learning in and from action, with emotional “buy-in” at its heart.
Conclusion
Those implementing social prescribing in different localities inevitably face hard choices about what and whom to include. Research on the sustainability of social prescribing remains limited, studies are required to ascertain which “holistic” models of social prescribing work best for which communities, who are the main beneficiaries of these approaches and how “buy-in” is best sustained
Cultural geographies of extinction: animal culture amongst Scottish ospreys
This paper explores cultural geographies of extinction. I trace the decline of the Scottish osprey during the nineteenth century, and its enduring, haunting presence in the landscape today. Taking inspiration from the environmental humanities, extinction is framed as an event affecting losses that exceed comprehension in terms merely of biological species numbers and survival rates. Disavowing the ‘species thinking’ of contemporary conservation biopolitics, the osprey’s extinction story pays attention to the worth of ‘animal cultures’. Drawing a hybrid conceptual framework from research in the environmental humanities, ‘speculative’ ethology and more-than-human geographies, I champion an experimental attention to the cultural geographies of animals in terms of historically contingent, communally shared, spatial practices and attachments. In doing so, I propose nonhuman cultural geographies as assemblages that matter, and which are fundamentally at stake in the face of extinction
Engagement Across Developmental Periods
The goal of this chapter is to provide a cohesive developmental framework and foundation for which to understand student engagement across early childhood, middle childhood, and adolescence. Guided by the bioecological theory of human development and the person-environment fit perspective, this chapter extends Finn\u27s participation-identification model of engagement by mapping student engagement within a larger developmental sequence. This chapter discusses student engagement within specific developmental periods that are tied to the developmental tasks, opportunities, and challenges unique to early childhood, middle childhood, and adolescence. Student engagement is found to be a nuanced developmental outcome, and the differences may be a result of the maturation of biological, cognitive, and socioemotional developmental tasks and the changing contextual landscape for the children and adolescents. Recommendations for future research as well as policy implications are also discussed
ESTUDIO DEL SENTIDO DE LAMINADO DE LA HOJALATA Y SU EFECTO EN LA ADHERENCIA DE RESINAS EPOXIFENÓLICAS
The existing relation between the adhesion of epoxilenolic resin and the sense of lamination of the tin plate by means of gravimetric, microscopic and electromechanical tests studies in a random sample that evaluates the resistance to the abrasion, the percentage of porosity and rugosity. The resin deposited in cross-sectional form presents up to 43,7% of diminution of mass given off by abrasion, with respect to the deposited one following the sense of lamination of the tin plate. lt has been observed that exists a proportional relation between the percentage of adhesion and the porosity produced by the effect «crosspiece». Also, the framework that the polymeric form with the substrate, in a cross-secional application, produces a high resistance to the electric flux that reduces the current passage up to 50.6%.Se estudia la relación existente entre la adherencia de la resina epoxifenólica y el sentido de laminación de la hojalata por medio de ensayos gravimétricos,microscópicos y electromecánicos en una muestra aleatoria que evalúa la resistencia a la abrasión,el porcentaje de porosidad y rugosidad.La resina depositada en forma transversal presenta hasta um 43.7% de disminución de masa desprendida por abrasión,respecto a la depositada siguiendo el sentido de laminación de la hojalata.Se ha observado que existe una relación proporcional entre el porcentaje de adherencia y la porosidad producida por el efecto "cruceta".Asimismo, el entramado que el polímero forma con el sustrato,en una aplicacíon transversal,produce una alta resistencia al flujo eléctrico que reduce el paso de corriente hasta en un 50.6
DECAPADO Y PASIVACIÓN DE TRANSPORTADORES METÁLICOS DE LÁMINAS LITOGRAFIADAS, PARA SECADO OXIDATIVO
The flow redox that forms between the metallic transporters and their surroundings, gives rise to the oxidating process of the alloy of which they are done. The application of average mechanics and chemicals remove formed oxides, contributing to their rehabilitation. Of tried acids, the spirit of salt to 20%V, was the solution that fulfilled the specifications for the removal and cleaning (pickling) of a metallic structure. Then, the formation of oxidating centers was slowed down by means of the aspersion with aqueous solution of sodium nitrite to 20%V. Also, the drying to temperatures majors of 160ºC optimizes the passivation. The results obtained to different times show a mini formation of rust, the one that to industrial conditions is despicable.El flujo redox que se forma entre los transportadores metálicos y su entorno, da lugar al proceso oxidativo de la aleación del cual están hechos. La aplicación de medios mecánicos y químicos remueven los óxidos formados, contribuyendo a su rehabilitación. De los ácidos ensayados, el ácido clorhídrico al 20%V, fue la solución que cumplió con las especificaciones para la remoción y limpieza (decapado) de una estructura metálica. Luego, la formación de focos oxidativos fueron retardados mediante la aspersión con solución acuosa de nitrito de sodio al 20%V. Asimismo, el secado a temperaturas mayores de 160 ºC optimiza el pasivado. Los resultados obtenidos a diferentes tiempos muestran una mínima formación de herrumbre, la que a condiciones industriales, es despreciable
