  2. Worldwide large-scale fluctuations of sardine and anchovy populations

    Worldwide large-scale fluctuations of sardine and anchovy populations

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Decade-scale regimes of sardine Sardinops sagax and anchovy Engraulis spp. have been observed in the productive coastal waters of the North-Western, North-Eastern and South-Eastern Pacific and the South-Eastern Atlantic. In each of these systems, the two genera fluctuate out of...
  3. There is No Lattice Preserving Natural Tensor Norm

    There is No Lattice Preserving Natural Tensor Norm

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We prove that for every natural tensor norm α, one can find a Banach lattice X such that the tensor product X ⊗ X endowed with the norm α does not have the Gordon-Lewis property and, therefore, cannot be isomorphic...
  4. LOCAL UNIQUENESS OF VECTOR MATRICES RELATED TO EXPONENTIAL SUMS

    LOCAL UNIQUENESS OF VECTOR MATRICES RELATED TO EXPONENTIAL SUMS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Enflo's approach to estimate exponential sums leads to problems in the interface between number theory, harmonic analysis, and geometry of euclidean space. In particular, he considers the following problem. Let θ be a p-periodic polynomial and assume that...
  5. How do Spanish EFL learners perceive grammar instruction and corrective feedback?

    How do Spanish EFL learners perceive grammar instruction and corrective feedback?

    Item type: Journal Article • Journal: Southern African Linguistics and Applied Language Studies
    This research study of an exploratory-interpretive nature mainly focuses on the role and effectiveness of grammar instruction and corrective feedback as controversial areas of language instruction of considerable debate in SLA research and L2 pedagogy. Since the question today is...
  6. Occurrence and ecological aspects of the two-fingered skink <em>Chalcides mauritanicus</em> in the Chafarinas Islands in North Africa

    Occurrence and ecological aspects of the two-fingered skink <em>Chalcides mauritanicus</em> in the Chafarinas Islands in North Africa

    Item type: Journal Article • Journal: African Journal of Herpetology
    The two-fingered skink, Chalcides mauritanicus, is a fossorial species from North Africa, where it has only been found at a few localities on sandy sea shores. Virtually nothing is known about its ecology. For the first time, we report the...
  7. How foreign and institutional directorship affects corporate dividend policy

    How foreign and institutional directorship affects corporate dividend policy

    Item type: Journal Article • Journal: Investment Analysts Journal
    The aim of this study is to examine how board composition affects dividend policies. Concretely, we analyse the effect of institutional directors on boards, also differentiating between pressure-sensitive and pressure-resistant institutional directors. Furthermore, the impact of foreign directors is also...
  8. A synthesis on the impact of non-native conifer plantations on ant and beetle diversity in north-western Patagonia

    A synthesis on the impact of non-native conifer plantations on ant and beetle diversity in north-western Patagonia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Softwood forestry with non-native tree species is increasing worldwide and especially in many developing countries of the Southern Hemisphere. Tree plantations are beneficial in environmental and socioeconomic aspects, but at the same time there are recognised costs associated with afforestation...
  9. Growth and biomass partitioning of nine provenances of <em>Quillaja saponaria</em> seedlings to water stress

    Growth and biomass partitioning of nine provenances of <em>Quillaja saponaria</em> seedlings to water stress

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Information on the morphological and physiological responses of seedlings to stressors, such as water stress, is required for successful early establishment of seedlings. We examined provenance variation in morphological and physiological traits of Quillaja saponaria Molina seeds from nine provenances...
  10. To what extent can CLIL learners’ oral competence outcomes be explained by contextual differences? Updated empirical evidence from Spain

    To what extent can CLIL learners’ oral competence outcomes be explained by contextual differences? Updated empirical evidence from Spain

    Item type: Journal Article • Journal: Southern African Linguistics and Applied Language Studies
    Based on the association between differences in learning contexts and differences in linguistic outcomes as supported by second language acquisition (SLA) research, this study examines the differential effects of particular contextually dependent variables on Spanish learners’ English oral communication skills...
