Interaction of Chinese institutions with host governments in dam construction: the Bui Dam in Ghana
No full textThe study analyses the role of Chinese companies and financing institutions and Ghanaian governmental agencies in planning and constructing the Bui Dam. The analysis focuses on the division of responsibilities between Sinohydro and China Exim Bank on the one side and the Ghanaian government on the other side. The findings show that environmental and resettlement planning for Bui was commissioned and financed by the Government of Ghana without Sinohydro’s involvement. The obligation of the firm is to abide by the environmental regulations that are monitored by the regulatory authorities. The role of Sinohydro consists in building the dam, maintaining the construction site, contracting workers, and providing for workers’ health and safety. The firm has no role in resettlement, which is carried out by the Bui Power Authority. While there is clear evidence that the Bui Power Authority does not follow the recommendations of the Resettlement Planning Framework, Sinohydro appears to abide largely by the conditions set out in the Environmental Impact Assessment study whose implementation is monitored by the Ghanaian Environmental Protection Agency and the Ghanaian Water Resources Commission
Top Management Team Diversity: A systematic Review
No full textEmpirical research investigating the impact of top management team (TMT)
diversity on executives’ decision making has produced inconclusive results.
To synthesize and aggregate the results on the diversity-performance
link, a meta-regression analysis (MRA) is conducted. It integrates more
than 200 estimates from 53 empirical studies investigating TMT diversity
and its impact on the quality of executives’ decision making as reflected
in corporate performance. The analysis contributes to the literature by
theoretically discussing and empirically examining the effects of TMT diversity
on corporate performance. Our results do not show a link between TMT
diversity and performance but provide evidence for publication bias. Thus,
the findings raise doubts on the impact of TMT diversity on performance
Chinese hydropower companies and environmental norms in countries of the global South: the involvement of Sinohydro in Ghana’s Bui Dam
No full textThe paper examines the role of environmental norms in Chinese overseas investment in hydropower dams, exemplified by Sinohydro’s involvement in the Bui Dam in Ghana. While the investment of Western companies in hydropower dams in the global South is decreasing owing to changing notions of sustainability in the West, the investment of Chinese companies in hydro dams in Africa, Southeast Asia and Latin America is accelerating at great speed. The emergence of Chinese companies in international markets in the context of China’s Going Abroad strategy has sparked a debate on whether China can be considered a norm-changer in international development. The paper considers this question in the context of the status of environmental norms in Sinohydro’s investment in Ghana’s Bui Dam. The paper argues that the role of international norms in Chinese investment is dependent on two factors: the contractual arrangements under which Chinese companies operate abroad and the political institutions of host countries
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Sexes also differ in the shape and strength of the metafemoral tooth, which is stronger in males. Compound eyes black in females but reddish brown in males. Morphometrics. See Table 1. Differential diagnosis. Synapsis puluongensis sp. nov. belongs to the S. birmanica group, as indicated by a combination of the following characters: hypomeral cavities present, genae unexpanded, frons unarmed, mesepisternal cavities absent, and upper longitudinal carina of male metatibia without brush of rusty setae. Species of the S. birmanica group may be clearly distinguished from those of S. ovalis, S. brahmina and S. tmolus groups by the presence of hypomeral cavities. The S. ritsemae group has expanded genae, in which it differs from the species of the S. birmanica group whose genae are unexpanded. Synapsis puluongensis sp. nov. can be distinguished from other known species of the group by the following characters: in S. puluongensis the elytral interval 2 is not swollen near the base (swollen in S. yama from northern and central Vietnam and Laos, S. horaki from northern Vietnam, S. dickinsoni from northern Thailand: Phukieo, S. ochii from northern Thailand: Chiang Mai and in S. masumotoi from Taiwan). Characters on the metafemora and elytral striae clearly differentiate S. puluongensis sp. nov. from the other species of the S. birmanica group recorded in Vietnam: both S. puluongensis sp. nov. and S. horaki have densely punctured metafemora on the ventral side, while S. yama has no punctures on the metafemur. In addition, S. puluongensis sp. nov. has coarse and closely spaced punctures on the elytral striae, which are absent or extremely weak in S. horaki (Figs 2 A–D). Synapsis puluongensis sp. nov. has hypomeral cavities without macrosetae, which distinguishes it from S. birmanica (hypomeral cavities are covered by a brush of rusty macrosetae). The new species has deep striae, whereas in S. birmanica the striae are feeble (Figs 2 E–F). Synapsis puluongensis sp. nov. is morphologically similar to S. naxiorum in its black and shiny dorsal side. However, the new species can be distinguished from S. naxiorum in having more punctures on the ventral side of the metafemora; elytral striae more densely punctate, intervals not punctate, and hypomeral cavities devoid of rusty setae (Figs 2A,G). The entire surface of S. puluongensis sp. nov. is black and shiny, in contrast to the opaque surface of S. punctata from Myanmar and S. roslihashimi from Malaysia. In addition, S. puluongensis sp. nov. has convex intervals, whereas S. roslihashimi and S. punctata have flat or only weakly convex intervals. In S. punctata and S. roslihashimi all margins of intervals are punctate, whereas they are impunctate in the new species. The new species can also be distinguished from S. punctata and S. roslihashimi by the absence of hypomeral rusty macrosetae. Etymology. The specific epithet puluongensis refers to the name of the type locality, Nature Reserve Puluong, Thanh Hoa Province, central Vietnam; adjective. Biology. The new species was collected in primary forests on limestone bedrock. The primary forests are characterized by a complex structure with various storeys, comprising an upper storey with emergent trees more than 35 m tall, belonging to Dipterocarpaceae and Combretaceae, a dominant lower storey (various tree species from 15 to 30 m tall), and a brush layer on the forest floor containing various herbs (Urticaceae, Araceae, Begoniaceae), lianas and parasitic plants (Connaraceae, Fabaceae, Orchidaceae, Loranthaceae).Published as part of Bui, Van Bac & Bonkowski, Michael, 2018, Synapsis puluongensis sp. nov. and redescription of S. horaki (Coleoptera: Scarabaeidae), with a key to Vietnamese species, pp. 407-418 in Acta Entomologica Musei Nationalis Pragae (Acta.

Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Mapping tourism, sustainability, and development in Southeast Asia
No full textTourism in Southeast Asia traces back many years, with early forms of travel including pilgrimage, and travel for trade, land, resources, missions and warfare. Tourism is thus a long-established economic, religious, and social activity in the region though mass tourism is a rather recent phenomenon which largely began to expand in the 1970s. In the past decades, tourism in Southeast Asia has seen unprecedented growth while the region has also undergone major changes in relation to markets, mobility and integration between countries in economic and political terms. The creation and expansion of the Association of Southeast Asian Nations from a defence alliance to a political and economic relationship between member countries is significant in the formation of the Southeast Asian identity. The Philippines were isolated from airline connections for many years but experienced tourism growth as access options improved. The chapter also presents an overview of the key concepts discussed in this book
