    Klump, Barbara Christina; van der Wal, Jessica Eva Megan; St Clair, James; Rutz, Christian (2015-05-20) - Journal article
    Several animal species use tools for foraging, such as sticks to extract embedded arthropods and honey, or stones to crack open nuts and eggs. While providing access to nutritious foods, these behaviours may incur significant ...
  • Context-dependent associations between heterozygosity and immune variation in a wild carnivore Evolutionary ecology and behaviour 

    Brock, P.M.; Goodman, S.J.; Hall, Ailsa Jane; Cruz, M.; Acevedo-Whitehouse, K. (2015-11-04) - Journal article
    Background: A multitude of correlations between heterozygosity and fitness proxies associated with disease have been reported from wild populations, but the genetic basis of these associations is unresolved. We used a ...
  • Context-dependent decision making in wild rufous hummingbirds 

    Morgan, Kate (University of St Andrews, 2013) - Thesis
    Conventional models of decision making assume that animals and humans will evaluate available options based on the benefit that they provide and then choose the option that provides the largest benefit. However, there ...

    Clarke, Esther; Reichard, Ulrich H.; Zuberbuehler, Klaus (2015-04-08) - Journal article

  • Contextual consent: ethical mining of social media for health research 

    Norval, Christopher; Henderson, Tristan (2017-01-26) - Conference item
    Social media are a rich source of insight for data mining and user centred research, but the question of consent arises when studying such data without the express knowledge of the creator. Case studies that mine social ...
  • Contextual determinants of political modernization in tribal Middle Eastern societies : the case of unified Yemen 

    Fattah, Khaled (University of St Andrews, 2010-05) - Thesis
    By all conventional measurements of modernization and development, from communication and education to bureaucracy and urbanization, Arab societies have been undergoing an impressive transformation. There is, however, a ...
  • Contextual effects of intergroup contact on outgroup prejudice 

    Christ, Oliver; Schmid, Katharina; Lolliot, Simon; Swart, Hermann; Stolle, Dietlind; Tausch, Nicole; Al-Ramiah, Ananthi; Wagner, Ulrich; Vertovec, Steven; Hewstone, Miles (2014-03-18) - Journal article
    We assessed evidence for a contextual effect of positive intergroup contact, whereby the effect of intergroup contact between social contexts (the between-level effect) on outgroup prejudice is greater than the effect of ...
  • Contextual imitation of intransitive body actions in a Beluga whale (Delphinapterus leucas) : a “do as other does” study 

    Abramson, José Z.; Hernández-Lloreda, Mª Victoria; Esteban, José-Antonio; Colmenares, Fernando; Aboitiz, Francisco; Call, Josep (2017-06-21) - Journal article
    Cetaceans are remarkable for exhibiting group-specific behavioral traditions or cultures in several behavioral domains (e.g., calls, behavioral tactics), and the question of whether they can be acquired socially, for example ...
  • Contextualising Classics teaching in Malawi : a comparative study 

    Nyamilandu, Steve Evans McRester Trinta (2016-05-18) - Thesis
    The thesis of this study is that Classical studies at the University of Malawi, Chancellor College, has been taught with almost no reference to its African context, yet the Classical world, as Ogilvie (1979:2) observed ‘is ...
  • Contextualism about evidential support 

    Brown, Jessica Anne (2016-03) - Journal article
    In this paper, I examine a contextualist thesis that has been little discussed in comparison with contextualism about knowledge, namely contextualism about evidential support. This seems surprising since, prima facie, ...
  • Continental carbonate facies of a Neoproterozoic panglaciation, north-east Svalbard 

    Fairchild, Ian J.; Fleming, Edward J.; Bao, Huiming; Benn, Douglas I.; Boomer, Ian; Dublyansky, Yuri V.; Halverson, Galen P.; Hambrey, Michael J.; Hendy, Chris; McMillan, Emily A.; Spötl, Christoph; Stevenson, Carl T. E.; Wynn, Peter M. (2016-02) - Journal article
    The Marinoan panglaciation (ca 650 to 635 Ma) is represented in north-east Svalbard by the 130 to 175 m thick Wilsonbreen Formation which contains syn-glacial carbonates in its upper 100 m. These sediments are now known ...
  • Continental growth and the crustal record 

    Hawkesworth, Chris; Cawood, Peter; Dhuime, Bruno (2013-12-08) - Journal item
    The continental crust is the archive of Earth history. The spatial and temporal distribution of the Earth's record of rock units and events is heterogeneous with distinctive peaks and troughs in the distribution of ages ...
  • The continental record and the generation of continental crust 

    Cawood, Peter Anthony; Hawkesworth, Chris; Dhuime, Bruno Philippe Marcel (2013-01) - Journal article
    Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth's record of rock units and events is heterogeneous; for example, ages of igneous crystallization, metamorphism, continental ...
  • Continental weathering following a Cryogenian glaciation : evidence from calcium and magnesium isotopes 

    Kasemann, S.A.; Pogge von Strandmann, P.A.E.; Prave, A.R.; Fallick, A.E.; Elliott, T.; Hoffmann, K.-H. (2014-06-15) - Journal article
    A marked ocean acidification event and elevated atmospheric carbon dioxide concentrations following the extreme environmental conditions of the younger Cryogenian glaciation have been inferred from boron isotope measurements. ...
  • conting : an R package for Bayesian analysis of complete and incomplete contingency tables 

    Overstall, Antony; King, Ruth (2014-06) - Journal article
    The aim of this paper is to demonstrate the R package conting for the Bayesian analysis of complete and incomplete contingency tables using hierarchical log-linear models. This package allows a user to identify interactions ...
  • Continued fractions which correspond to two series expansions and the strong Hamburger moment problem 

    Sri Ranga, A. (University of St Andrews, 1984) - Thesis
    Just as the denominator polynomials of a J-fraction are orthogonal polynomials with respect to some moment functional, the denominator polynomials of an M-fraction are shown to satisfy a skew orthogonality relation with ...
  • The continuing story of SN IIb 2013df: new optical and IR observations and analysis 

    Szalai, Tamás; Vinkó, József; Nagy, Andrea P.; Silverman, Jeffrey M.; Wheeler, J. Craig; Dhungana, Govinda; Marion, G.
