Social Work and a New Social Order - Challenging Neo-liberalism's Erosion of Solidarity

The world in which social work operates today is a very different world from that in which most of us took their social work training, and the changes we are facing are profound. This paper argues that these changes are not merely a regime change in social policy but that they are essentially about a re-ordering of social relationships and attempt to model them on neo-liberal ideas. In view of these pressures it is understandable that social workers often try to ignore those changes and withdraw into a private world of therapeutic relationships in which the methods they trained in are made to be still valid, or they simply go along with new service delivery designs without asking too many questions. Both reactions fail to question what the "social" can still mean in the light of these changes and how social workers can fulfil their mandate to be responsible for the social dimension of public life. Nothing less than a head-on challenge of the basic presuppositions of neo-liberalism (Willke 2003) and their manifold applications to social service delivery systems will thereby suffice.

Geotechnical engineering characterization of sediments at DSDP Leg 72 Holes

The hydraulic piston coring device (HPC-15) allows recovery of deep ocean sediments with minimal disturbance. The device was used during Leg 72 of the Deep Sea Drilling Project (DSDP) aboard the Glomar Challenger. Core samples were recovered from bore holes in the Rio Grande Rise in the southwest Atlantic Ocean. Relatively undisturbed sediment cores were obtained from Holes 515A, 516, 517, and 518. The results of shipboard physical property measurements and on-shore geotechnical laboratory tests on these cores are presented in this chapter. A limited number of 0.3 m cores were obtained and used in a series of geotechnical tests, including one-dimensional consolidation, direct shear, Atterburg limit, particle size analysis, and specific gravity tests. Throughout the testing program, attention was focused on assessment of sample disturbance associated with the HPC-15 coring device. The HPC-15 device limits sample disturbance reasonably well in terrigenous muds (clays). However, sample disturbance associated with coring calcareous sediments (nannofossil-foraminifer oozes) is severe. The noncohesive, granular behavior of the calcareous sediments is vulnerable to severe disturbance, because of the design of the sampling head on the device at the time of Leg 72. A number of modifications to the sampling head design are recommended and discussed in this chapter. The modifications will improve sample quality for testing purposes and provide longer unbroken core samples by reducing friction between the sediment column and the sampling tool.

Hegemonía y contrahegemonía en la América Latina de hoy. Apuntes hacia una nueva época

El despliegue sobre el presente latinoamericano de la problemática gramsciana de la hegemonía, exige tanto una elucidación de yerros y simplificaciones en la utilización de la categoría original, como un repaso histórico de la evolución social y cultural del continente. La estructura de clase, los modos de la lucha social y política, la configuración organizacional y la subjetividad de los luchadores, se han modificado profundamente en estos años, enmarcadas por una ofensiva de alcance estratégico del gran capital. Las concepciones gramscianas pueden (deben) constituir un auxilio fundamental a la hora de volver a pensar en una perspectiva de transformación social radical, que eluda el doble riesgo de la adaptación al orden existente, en un extremo, y un «choque frontal¼ contra el mismo que cambie eficacia real por radicalismo programático. Se encontrarán allí herramientas para examinar críticamente el pasado y el presente del pensamiento y las prácticas contestatarias de nuestro continente; y proyectarlas en dirección a su perspectiva futura.

Subacute neuropathological effects of microplanar beams of x-rays from a synchrotron wiggler.

Microplanar beam radiation therapy has been proposed to treat brain tumors by using a series of rapid exposures to an array of parallel x-ray beams, each beam having uniform microscopic thickness and macroscopic breadth (i.e., microplanar). Thirty-six rats were exposed head-on either to an upright 4-mm-high, 20- or 37-microns-wide beam or to a horizontal 7-mm-wide, 42-microns-high beam of mostly 32- to 126-keV, minimally divergent x-rays from the X17 wiggler at the National Synchrotron Light Source at Brookhaven National Laboratory. Parallel slices of the head, separated at either 75 or 200 microns on center, were exposed sequentially at 310-650 grays (Gy) per second until each skin-entrance absorbed dose reached 312, 625, 1250, 2500, 5000, or 10,000 Gy. The rats were euthanized 2 weeks or 1 month later. Two rats with 10,000-Gy-entrance slices developed brain tissue necrosis. All the other 10,000- and 5000-Gy-entrance slices and some of the 2500- and 1250-Gy-entrance slices showed loss of neuronal and astrocytic nuclei and their perikarya. No other kind of brain damage was evident histologically in any rat with entrance absorbed doses < or = 5000 Gy. Brain tissues in and between all the 312- and 625-Gy-entrance slices appeared normal. This unusual resistance to necrosis is central to the rationale of microplanar beam radiation therapy for brain tumors.

Emergent Brazil and the Curse of the ‘Hen’s Flight’. CEPS Working Document No. 379, 27 February 2013

The ‘Emergent Brazil’ growth model is reaching its limits. Its main engines have been slowing significantly since the beginning of the global financial and economic crisis. Even its much-praised predictable macroeconomic policy has been eroded by political interference. Inflationary pressures are growing and GDP performance is anaemic. As ominous, Brazil cannot compensate for its domestic deficiencies with an export drive. Commodity exports are suffering with the world economic slow-down and the manufacturing industries’ competitiveness is in sharp decline. Brazil has put all its trade negotiation eggs into the South American and WTO baskets, and now its export market share is threatened by the Doha Round paralysis, the Latin American Alianza del Pacífico, and the US-led initiatives for a Trans-Pacific Partnership and a trade and investment agreement with the EU. Paradoxically, this alarming situation opens a window of opportunity. There is a mounting national consensus on the need to tackle head-on the country’s and its industries’ lack of competitiveness. That means finding a solution to the much-decried ‘Brazil Cost’ and stimulating private-sector investment. It also entails an aggressive trade-negotiating stance in order to secure better access to foreign markets and to foster more competition in the domestic one. The most promising near-term goal would be the conclusion of the EU–Mercosur trade talks. A scenario to overcome the paralysis of these negotiations could trail two parallel paths: bilateral EU–Brazil agreements on ‘anything but trade’ combined with a sequencing of the EU–Mercosur talks where each member of the South American bloc could adopt faster or slower liberalisation commitments and schedules.
