We report the first foodborne outbreak caused by Cryptosporidium parvum in Finland. The outbreak occurred among personnel of the Public Works Department in Helsinki, who had eaten in the same canteen. 72 persons fell ill with diarrhoea, none was hospitalised. Four faecal samples obtained from 12 ill persons were positive for Cryptosporidium by an antigen identification assay and microscopy. The vehicle of infection could not be identified with certainty but a salad mixture was suspected.

The Lake Rudolf Rift Valley Expedition was designed to carry out many different lines of investigation in the Lake Rudolf Basin. One of the chief of these was a study of the geological history of that part of the East African Rift Valley. The expedition was assisted financially by The Royal Society, The Geological Society of London, The Royal Geographical Society, The Percy Sladen Trustees and the Geographical and Geological Sections of the British Association. A general description of the activities of the Expedition was given in a paper read before the Royal Geographical Society (Fuchs 1935). Owing to the tragic loss of two members of the expedition, Dr W. S. Dyson and Mr W. R. H. Martin, two fruitless months were spent searching for them. Consequently a great amount of the work planned for the east side of the lake had to be abandoned. Nevertheless, the considerable distance travelled within the 50,000 sq. miles of the Rudolf Basin has enabled me to make out the chief events of its geological history. I am very much indebted to all those who assisted us in the field and at home, in particular to the Kenya Government, the Officers of the King’s African Rifles, and Mr H. L. Sikes of the Public Works Department; I would also like to thank Mr A. M. Champion, Provincial Commissioner of Turkana, who wholeheartedly assisted us in every way possible both in the field and at home, for he has placed at my disposal his own excellent topographical maps and his extensive observations on the geology of the area. I am also deeply indebted to Professor O. T. Jones, Mr Henry Woods and Mr W. Campbell Smith for their criticisms. Mr Campbell Smith has also given me provisional identifications of the rocks.

Cleaning Streams in Cook County, IL: Forest Preserves, Water Pollution, and Interwar Environmentalism in the Chicago Region

Forest Preserve

In 1916, the Forest Preserve District of Cook County began acquiring land to create a natural retreat for Chicagoans in that booming metropolitan region. Since district officials acquired many properties along county streams, water pollution soon interfered with their mission of creating an urban wilderness for recreational pleasure. To address the problem, in 1931, county leaders appointed the Clean Streams Advisory Committee that collaborated with forest preserve staff members to pressure polluters to clean-up their operations and to persuade enforcement agencies to prosecute ongoing offenders. They also lobbied the Public Works Administration to earmark New Deal funding for sewage treatment in Cook County. Their efforts suggest that early activism against water pollution in American cities emerged not only from efforts to ensure clean drinking water, but also struggles to protect nature. The interwar campaign to clean forest preserve streams anticipated the goals of the federal Clean Water Act (1972) to make all American waterways fishable and swimmable. The movement also preceded the burst of anti-pollution activism that historians have documented in U.S. suburbs after WWII and laid the groundwork for postwar efforts to mitigate water pollution in Cook County.

Simultaneous Influence

This study aims to the influence of employee discipline, learning and supervision on the service performance of public works in Bina Marga office of Ponorogo Regency. The results showed the simultaneous influence of discipline and organizational learning behavior on the performance. The results empirically prove that discipline and organizational learning behavior is highly relevant as a measuring tool with sufficient accuracy to determine the service performance of service employees in the Public Works and Bina Marga Office of Ponorogo Regency. The simultaneous influence of employee discipline with learning behavior of organization on employees in the licensing sector at PU in Ponorogo Regency which has an impact on the performance or performance of public services can be illustrated that Public Works Department employees as a learning organization are not far from the mindset that only senior management can and do all the thinking for the whole institution. The learning behavior of organization challenges all employees to utilize their mental resources and potential, with the hope that every employee in the PU office can build their own community based on the principles of freedom, humanity, and a collective desire to learn. As a managerial implication, it can be said that discipline in the work process at the Ponorogo District Public Works office goes hand in hand with the willingness of employees to increas discipline and organizational learning behavior which are correlated to form service performance

Cryptosporidium Oocysts

Of 1 346 faecal samples from the Chikwawa and Thyolo districts of Malawi, analysed for the presence of Cryptosporidium oocysts between October 2001 and May 2003, 61.3 % were from cattle (29.8 % of these were from calves < 6 months old). Cryptosporidium oocysts were detected during all three seasons studied in Chikwawa and Thyolo. In Chikwawa, 13.6 % of adult cattle and 11.7 % of calves were infected, compared to 28.9 % of adult cattle and 36.7 % of calves in Thyolo. Dependent on season, between 7.8 % and 37.7 % (Chikwawa) and 16.7 % and 39.3 % (Thyolo) of cattle samples contained oocysts. In Chikwawa, the highest percentage of infections occurred in the cool season, whereas in Thyolo, the highest percentage of infections occurred in the dry season. Faecal samples from goats [n = 225], pigs [n = 92], sheep [n = 6]), rabbits, guinea pigs, chickens, ducks, turkeys, doves and guinea fowls were also analysed. Up to 5.6 % of goat samples contained oocysts in Chikwawa, compared to between 16.7 % and 39.3 % in Thyolo. Again, in Chikwawa, the highest percentage of infections occurred in the cool season and the lowest in the rainy season, whereas, in Thyolo, the highest percentage of infections occurred in the dry season and the lowest in the cool season. In pigs, more infections were detected in the dry season in Chikwawa, but infections in the cool season were similar (17.7 %), whereas in Thyolo, infections occurred in all three seasons (17.9 % in the rainy season, 25 % in the cool season and 60 % in the dry season). Often diarrhoeic, oocyst positive cattle faecal samples collected from Chikwawa and subjected to PCR-RFLP, four oocyst positive samples (two from heifers, one from a cow and one unknown) were amplified at an 18S rRNA and Cryptosporidium oocyst wall protein (COWP) loci. RFLP of the 18S rRNA locus indicated that Cryptosporidium parvum, Cryptosporidium hominis, Cryptosporidium bovis and / or Cryptosporidium ryanae DNA, or a mixture of them was present. Cryptosporidium parvum DNA was identified in one sample that amplified at the COWP locus, indicating the presence of the major zoonotic Cryptosporidium species in Malawi.
