Bodo cygnus Patterson and Simpson 1996
No full text<i>Bodo cygnus</i> Patterson and Simpson, 1996 <p>(fi gures 1g, 2k, l)</p> <p> <i>Description.</i> Cell 8-13 Mm long, elliptical, with subapical indentation from which two unequal fl agella emerge. The anterior fl agellum is as long as the cell and may wrap around the anterior end of the cell during feeding. The acronematic posterior fl agellum is about 2.5 times the length of the cell. Cells have a spiral groove that is easy to overlook and that extends from the subapical indentation to the posterior end of the cell. Cells move by rotating swimming movements. Sometimes commonly observed.</p> <p> <i>Remarks.</i> This species was fi rst described from hypersaline marine sites by Patterson and Simpson (1996) and with lengths from 8 to 12 Mm. Our observations are in accord with those of Patterson and Simpson (1996). <i>Bodo cygnus</i> may be confused with <i>B. designis</i> Skuja, 1948 in general appearance, rotational swimming movements and cell length, but it can be distinguished by its spiral groove. The groove is hard to see in swimming cells. Previously reported large <i>B. designis</i> may be referable to <i>B. cygnus</i> because the spiral groove may have been overlooked. Careful observation is needed to distinguish these two species.</p>Published as part of <i>Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34</i> on pages 490-49
Woud: Trek je even terug in je concentratiebubbel
No full textHet was zo’n zonnige lentedag; heerlijk om lekker buiten te zijn. Ik zat binnen, in een vergadering – met de nodige moeite om mijn aandacht erbij te houden. Liever keek ik door het raam naar kersenbloesems. Afgeleid raken, wegdromen ofjuist onrustig zijn en niet stil kunnen zitten. Herkenbaar? Vast wel; iedereen heeft wel eens moeite om zich te concentreren. Maar voor sommige kinderen is dit een dagelijkse worsteling. Hoe ga je daar op een goede manier mee om in eenklaslokaal, een omgeving met constante prikkels en afleiding?

Confronting Language Fetishism in Practice
No full textThe notion of fetishism, in the most general interpretation of the term, is one in which an object is afforded extra-natural properties, or is animated and brought to life as an agentive “thing”. In this sense, the notion of language as a fetish (Simpson & O’Regan, 2018; Simpson, 2018) imagines languages such as English as bearing all kinds of extra-linguistic properties: As a product or service (Singh & Han, 2008), as a commodity or resource which speakers exchange (Heller, 2016), as a mythical “thing” which does this or that to people (Pennycook, 2007), and even as a cause of social suffering (Piller & Cho, 2013; Piller, Takahashi, & Watanabe, 2010). What we offer in this chapter is a critical engagement with the notion of fetishism as it relates to a larger body of work on language, language policy, and political economy, in respect of language alienated and fetishised in standard forms; the recasting of language not as a social product, but as a form of legal property, owned and traded by individuals; and the necessity of fetishised forms of language in the functioning of the “free” market. We conclude by underscoring the notion of fetishism as consisting in illusions which exist not in theory, but in practice, and with a call for future research to examine the fetishism of languages in the practice of the market. We therefore argue that calls for policy to develop critical reflexive awareness in speakers, while certainly important, are not in themselves sufficient for moving beyond fetishistic notions of language
Simpson\u27s paradox
No full textPojav, ko se neka povezava med dvema spremenljivkama pojavi, kadar preučujemo celotno populacijo hkrati in izgine ali se pojavi v obratni povezavi, kadar jo delimo na podskupine, imenujemo Simpsonov paradoks. S pomočjo mere povezanosti ga lahko zapišemo v treh oblikah: kot asociacijski preobrat, Yulov asociacijski preobrat ali kot paradoks združenja. Pojav paradoksa lahko srečamo na raznolikih področjih, za lažjo predstavo pa si lahko pomagamo z grafi, vektorji, mozaičnimi prikazi, pa tudi usmerjenimi acikličnimi grafi. Obstajajo tudi raznolika orodja za pomoč pri prepoznavanju pojava Simpsonovega paradoksa na podatkih. Simpsonov paradoks lahko povežemo z vzročnim sklepanjem, ki nam je v pomoč tudi pri razlagi, zakaj pride do pojava paradoksa in kako se odločati pri obravnavi podatkov - ali upoštevati delitev na podskupine ali ne. Prav tako ga lahko povežemo z načelom gotovosti, za katerega Simpsonov paradoks predstavlja protiprimer veljavnosti načela.The phenomenon in which a certain association between two variables occurs when studying the entire population and then disappears or appears in the opposite direction when the population is divided in subpopulations, is known as Simpson\u27s paradox. Using a measure of strength of the probabilistic association we can formulate Simpson\u27s paradox in three forms: association reversal, Yule\u27s association reversal or amalgamation paradox. We can encounter the phenomenon of the paradox in various fields and for better visual display we can use plots, vectors, mosaic plots and also directed acyclic graphs. There are also some tools that help with identifying the occurrence of Simpson\u27s paradox in data. Simpson\u27s paradox can be connected to causal reasoning, which also helps with explaining why the paradox occurs and how to decide when dealing with data - whether to consider subpopulation division or not. It can also be linked to the sure-thing principle, for which Simpson\u27s paradox serves as a counterexample to the principle\u27s validity

The relationship between dietary supplement use in late pregnancy and birth outcomes: a cohort study in British women

The relationship between dietary supplement use in late pregnancy and birth outcomes: a cohort study in British women. BJOG 2010; DOI: 10.1111/j.1471-0528.2010.02549.x.Objective To examine the relationship between dietary supplement use during pregnancy and birth outcomes.Design A prospective birth cohort.Setting Leeds, UK.Sample One thousand two hundred and seventy-four pregnant women aged 18201345 years.Methods Dietary supplement intake was ascertained using three questionnaires for the first, second and third trimesters. Dietary intake was reported in a 24-hour dietary recall administered by a research midwife at 8201312 weeks of gestation. Information on delivery details and antenatal pregnancy complications was obtained from the hospital maternity records.Main outcome measures Birthweight, birth centile and preterm birth.Results Reported dietary supplement use declined from 82% of women in the first trimester of pregnancy to 22% in the second trimester and 33% in the third trimester. Folic acid was the most commonly reported supplement taken. Taking any type of daily supplement during any trimester was not significantly associated with size at birth taking into account known relevant confounders. Women taking multivitamin-mineral supplements in the third trimester were more likely to experience preterm birth (adjusted OR = 3.4, 95% CI 1.2, 9.6, P = 0.02).Conclusions Regular multivitamin2013mineral supplement use during pregnancy, in a developed country setting, is not associated with size at birth. However, it appears to be associated with preterm birth if taken daily in the third trimester. The mechanism for this is unclear and our study's findings need confirming by other cohorts and/or trials in developed countries

Melk in je koffie: Een onderzoek met mogelijkheden
No full textIn 1999 stond in de NRC een column van Karel Knip over de vraag uit de wetenschapsquiz of je direct een wolkje melk in je koffie moet doen als de bel gaat of dat je dat beter kunt doen als je terugkomt van de buitendeur. De column geeft een mooi beeld van wat er allemaal kan komen kijken als je wat dieper op de vraag ingaat. Er blijken veel mogelijkheden te zijn om ook in de klas met deze vraag aan de slag te gaan!ImPhys/Docente
