Domestic demand-side management (DSM): Role of heat pumps and thermal energy storage (TES) systems
No full textNitrogen management is essential to prevent tropical oil palm plantations from causing ground level ozone pollution
No full textMore than half the world’s rainforest has been lost to agriculture
since the Industrial Revolution. Among the most widespread tropical
crops is oil palm (Elaeis guineensis): global production now
exceeds 35 million tonnes per year. In Malaysia, for example, 13%
of land area is now oil palm plantation, compared with 1% in 1974.
There are enormous pressures to increase palm oil production for
food, domestic products, and, especially, biofuels. Greater use of
palm oil for biofuel production is predicated on the assumption
that palm oil is an ‘‘environmentally friendly’’ fuel feedstock. Here
we show, using measurements and models, that oil palm plantations
in Malaysia directly emit more oxides of nitrogen and volatile
organic compounds than rainforest. These compounds lead to the
production of ground-level ozone (O3), an air pollutant that damages
human health, plants, and materials, reduces crop productivity,
and has effects on the Earth’s climate. Our measurements show
that, at present, O3 concentrations do not differ significantly over
rainforest and adjacent oil palm plantation landscapes. However,
our model calculations predict that if concentrations of oxides of
nitrogen in Borneo are allowed to reach those currently seen over
rural North America and Europe, ground-level O3 concentrations
will reach 100 parts per billion (109) volume (ppbv) and exceed
levels known to be harmful to human health. Our study provides
an early warning of the urgent need to develop policies that
manage nitrogen emissions if the detrimental effects of palm oil
production on air quality and climate are to be avoided
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
