René Sand (1877-1953) and His Contribution to International Social Work, IASSW-President 1946 – 1953

The extraordinary significance of the life and work of René Sand lies in his central position as a mediator, promoter and coordinator of social work on an increasingly international level during the interwar-period and it can hardly be overestimated. To approach the achievements of Sand’s life and work you have to work archaeologically as he does not seem to have left any traces in the literature on social history. In Germany, even within the field of social work his name is hardly known. His biographical sketch and his importance for the development of the profession of social work have fallen into oblivion. The situation is a little different in the French-speaking countries where a biography has been published (compare Anciaux 1988a, b, c) which contains a detailed record of Sand’s writings. Altogether this lack of interest is regrettable because it doesn’t consider that René Sand is exemplary and in some parts fundamental to the emergence of professional social work in the 1920s in Belgium and Europe. Professional social work was established by a consequent international orientation and an emancipation from neighbouring fields such as social medicine and hygiene. Therefore it is a rewarding task to draw attention to this pioneer of social work and make the public appreciate his work. I want to emphasize explicitly that in this portrait Sand’s achievements concerning social work will be the main focus, even if this is an inevitable reduction of his accomplishments in the field of medicine and social medicine.

The Storm Surge Event of the Netherlands in 1953

A disastrous storm surge hit the coast of the Netherlands on 31 January and 1 February 1953. We examine the meteorological situation during this event using the Twentieth Century Reanalysis (20CR) data set. We find a strong pressure gradient between Ireland and northern Germany accompanied by strong north-westerly winds over the North Sea. Storm driven sea level rise combined with spring tide contributed to this extreme event. The state of the atmosphere in 20CR during this extreme event is in good agreement with historical observational data

Wahlbeteiligung im Lebensverlauf. A-P-K-Analysen für die Bundesrepublik Deutschland in der Zeit von 1953 bis 1987

Im vorliegenden Beitrag soll geklärt werden, ob der Wandel in der Beteiligung an Bundestagswahlen mit dem kohortenspezifischen Wahlverhalten politischer Generationen zusammenhängt, und welche Rolle dabei Alters- und Periodeneffekte spielen. Dabei steht auch die Frage zur Diskussion, ob es nach der Bundestagswahl im Jahre 1972 tatsächlich zu einem Rückgang der Wahlbeteiligung gekommen ist oder ob dieses Phänomen auf einem Artefakt der amtlichen Wahlstatistik beruht. Diese beiden Fragestellungen werden für unterschiedliche Kohorten mit retrospektiven Lebensverlaufsdaten untersucht. Zum einen wird festgestellt, dass die Wahlbeteiligung in den 1970er und 1980er Jahren tatsächlich wegen einer gewachsenen Zahl bekennender Nichtwähler gesunken war. Zum anderen bestätigt es sich, dass der soziale Wandel in der Höhe der Wahlbeteiligung vornehmlich auf das geänderte Wahlverhalten in der Abfolge politischer Generationen zurückzuführen ist. Während das Alter der Wahlberechtigten dabei kaum eine Rolle spielte, waren Periodeneffekte, die Veränderungen von gesellschaftlichen Verhältnissen und des Politikangebots widerspiegelten, von sekundärer Bedeutung.

Springtime Nutrient and Phytoplankton Dynamics on Georges Bank

The dynamics of phytoplankton and nutrients before, during and after the winter-spring bloom on Georges Bank were studied on 6 monthly survey cruises from January to June 1999. We measured hydrography, phytoplankton cell densities, chlorophyll a, dissolved inorganic nutrients (NO3 + NO2, NH4, Si(OH)(4), PO4), dissolved organic nitrogen (DON) and phosphorus (DOP), particulate organic carbon (POC) and nitrogen (PON) and total particulate phosphorus (TPP). We present evidence that phytoplankton production may be significant year-round, and that the winter-spring bloom may have started in January. From January to April the phytoplankton was comprised almost exclusively of diatoms, reaching cell densities in March and April of ca. 450 cells ml(-1); chlorophyll a concentrations exceeded 10 mug l(-1) in April. Diatoms decreased to relatively low levels in May (< 50 x 10(3) cells l(-1)) and increased again in June (>300 x 10(3) cells l(-1)). Densities of dinoflagellates and nanoflagellates were low (< 10 x 10(3) cells l(-1)) from January to April, and increased in May and June to nearly 300 x 10(3) cells l(-1). Nitrate + nitrite concentrations in January were <3 muM in the shallow, central portion of the bank and decreased steadily each month. Silicate was also <3 muM over an even larger area of the central bank in January and declined to <1.5 muM over most of the Bank in April. The data suggest that silicate depletion, not DIN, contributed to the cessation of the diatom bloom. Regeneration of silicate occurred in May and June, presumably as a result of rising water temperatures in late spring which increased the dissolution rate of diatom frustules from the earlier diatom bloom. Dissolved organic nitrogen may have been utilized at the start of the winter-spring bloom; concentrations were ca, 14 muM in January, dropping to < 6 mug l(-1) in February, after which DON concentrations steadily rose to > 15 mug l(-1) in June. Overall micro-and nanoplankton biomass, measured as POC, PON and TPP, increased over the 6 mo period, as did nutritional quality of that biomass as indicated by declining C:N ratios. Our results suggest there may have been an increase in the heterotrophic component of the plankton in May and June which coincided with a second burst in diatom abundance. We discuss general features of planktonic production and nutrient dynamics with respect to year-round production on the Bank.
