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
Researching tourism and development in Southeast Asia: Methodological insights
No full textTourism for development has become an essential research field in its own right, also in Southeast Asia. Researchers and scholars within the region, but more broadly from around the world, dedicate themselves to understanding how to use tourism most efficiently as a development strategy. Much of this research is based on anthropological approaches, with field work as the prime method employed. However, very little has been said about the challenges that researchers with different positionalities encounter in the field, such as access to the field, language or working with interpreters, and power relations. This chapter therefore debates these challenges and points towards ways to address these by drawing on examples from the authors’ fieldwork in foreign and familiar fields. Examples include discussions on the above-mentioned challenges, with a specific focus on the emic versus etic perspective, also seen as the ‘insider-outsider’ debate. In doing so, the chapter demonstrates that there is no ‘ideal’ position from which to do research in the Southeast Asia. It deromanticises the idea of fieldwork at home as delivering more truthful accounts of the field and, finally, points towards the need for reflexivity in order to make our field research in Southeast Asia more robust and effective
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
Sharp Lp estimates for Schrödinger groups on spaces of homogeneous type
No full textWe prove an Lp estimate (Equation Presented) for the Schrödinger group generated by a semibounded, self-adjoint operator L on a metric measure space X of homogeneous type (where n is the doubling dimension of X). The assumptions on L are a mild Lp0 → Lp' 0 smoothing estimate and a mild L2 → L2 off-diagonal estimate for the corresponding heat kernel e -tL. The estimate is uniform for φ varying in bounded sets of S(R), or more generally of a suitable weighted Sobolev space. We also prove, under slightly stronger assumptions on L, that the estimate extends to (Equation Presented) with uniformity also for θ varying in bounded subsets of (0,+∞). For nonnegative operators uniformity holds for all θ > 0

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

Parvimyrma sangi Eguchi & Bui, 2007, sp. nov.
No full textParvimyrma sangi sp. nov. (Figs. 1–10) Holotype worker: Tay Yen Tu N. P., 21 ° 10 ’ 11 ”N, 106 ° 43 ’06”E, 435 m alt., Bac Giang Prov., N. Vietnam, 28 May 2004 (K. Eguchi leg., colony Eg04-VN- 138) [IEBR]. Paratypes: 42 pinned and 2 slide-mounted workers from the same colony as holotype [IEBR, BMNH, MCZC, MHNG, MNHA, ACEG]. Worker description. Tiny species with characteristics given in the generic diagnosis. Body pale yellowish brown, much depigmented, covered with short standing hairs. Head in full-face view roughly elongaterectangular, in profile thin dorsoventrally with flattened dorsal and ventral margin; the dorsum of head weakly rugoso-reticulate except almost smooth anteromedian part of frons; the lateral face of head weakly rugosoreticulate; clypeus largely smooth, with its anteromedian margin truncate; outer surface of mandible smooth; mandibular teeth triangular and sharp, gradually reduced in size from the apical teeth to the basal teeth; antennal scape short, reaching only 7 / 10 – 3 / 4 of the distance from the anterior margin of clypeus to the posterior margin of head (Fig. 2); antennal segments III–IX much shorter than broad; the apical antennal segment ca. 3 times as long as the preapical segment; mesosoma smooth except lower part of mesopleuron which is very weakly reticulate; gaster entirely smooth. Worker measurements and indices. Holotype: HL 0.37 mm, HW 0.26 mm, SL 0.21 mm, ML 0.42 mm, FL 0.19 mm, CI 71, SI 81, FI 71. Paratypes (n= 4): HL 0.37 mm, HW 0.26–0.27 mm, SL 0.21 mm, ML 0.40–0.41 mm, FL 0.19–0.20 mm, CI 71–73, SI 78–79, FI 71–74. Bionomics. The type series was obtained from one of ten cheese bait traps (small plastic tubes with several entrances containing powdered cheese as bait) buried ca. 10 cm underground in a well-developed forest at ca. 435 m alt. The circumstantial evidence as well as its morphological features (depigmentation and flat body without eyes) suggest that Parvimyrma sangi is a subterranean nester and forager.Published as part of Eguchi, Katsuyuki & Bui, Tuan Viet, 2007, Parvimyrma gen. nov. belonging to the Solenopsis genus group from Vietnam (Hymenoptera: Formicidae: Myrmicinae: Solenopsidini), pp. 39-47 in Zootaxa 1461 on pages 44-46, DOI: 10.5281/zenodo.27373
Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
