No full textCameraria rhynchophysa Bai, sp. nov. Figs. 3, 8, 12 Diagnosis. Cameraria rhynchophysa Bai, sp. nov. is similar to C. jiulianshanica Bai, sp. nov. and C. trizosterata Kumata with the forewing having three whitish fasciae, but can be distinguished by the following characters: in C. rhynchophysa fasciae of forewing are not interrupted, and there is also a basal white streak. Second fascia of C. jiulianshanica and third fascia of C. trizosterata are interrupted, and basal white streak is absent. C. rhynchophysa shows remarkable similarity to C. jiulianshanica in the male genitalia structures, except for phallus. C.rhynchophysa has a beak-shaped process at basal 2 / 5 of the phallus, and vesica has a horn-shaped cornutus; C. jiulianshanica lacks these. Description. Adult (Fig. 3). Wingspan 5.0 mm. Head and antenna whitish; flagellum with pale milk-yellow rings. Labial palpus whitish, outer surface with a fuscous longitudinal stripe extending from base to apex. Thorax and tegula whitish. Forewing grey-brownish, with whitish markings edged black along outer side; basal streak about 1 / 8 as long as forewing; 3 whitish fasciae extending from basal 1 / 4, basal 3 / 4 and near apex of costa to dorsum respectively, oblique inwards, arranged nearly parallel; costa between the second and third fascia black; cilia pale grey-brownish. Hindwing and its cilia pale grey. Foreleg with coxa and femur whitish; tibia with ventral surface and apical half of dorsal surface fuscous, basal half of dorsal surface whitish; tarsus whitish, with a fuscous ring. Mid- and hindlegs whitish; mid tibia with 3 black oblique fasciae on outer surface, one of these fasciae placed at distal end of tibia, mid tarsus with 3 black rings; hind tibia grey-brownish on outer surface, black apically, with whitish long hairs above, hind tarsi with 2 black rings.

The influence of tourism on the sustaining of vernacular architechtural tradition embodied in the Bai and Naxi dwellings in Yunnan, China.
No full textYunnan is an economically underdeveloped region in south-western China, in which many ethnic settlements are preserved well. Within the last two decades, many ethnic communities at a grass-roots social level have been conducting a series of tourism-related developments of Bai and Naxi dwellings in Yunnan. They are altering, restoring, rebuilding, refurbishing and renewing ordinary Bai or Naxi dwellings into multi-function dwellings, which are not only the residential homes of families, but are also capable of providing an exotic cultural experience for tourists‘ consumption. Nevertheless, Bai and Naxi dwellings are representations of a living culture, embodying a complex set of vernacular architectural traditions which have been transmitted for many generations. When the Bai and Naxi dwellings are involved in tourism development, the transmission and adaptation of these vernacular architectural traditions are changed, and the manner in which such traditions aresustained in new circumstances becomes an interesting problem. This study explores the influence of tourism development on sustaining the vernacular architectural tradition embodied in Bai and Naxi dwellings in Yunnan, China. The researcher has conducted three rounds of fieldwork, choosing 30 Bai and Naxi dwellings involved in tourism development, from four ethnic minority settlements in Yunnan, for investigation. Observation, interview and questionnaire have been applied to collect data, and template analysis has been used to analyse the data. The results of the analysis show that if tourism development is conducted mainly at a community level, itcan enhance the sustaining of the vernacular architectural tradition embodied in Bai and Naxi dwellings. In summary, the sustaining of vernacular architectural tradition is not simply influenced by the nature of tourism, but is highly dependent on the social level of the developers, the construction pattern they choose, and the socio-cultural interaction they produce
Quantifying forest elephant social structure in Central African bai environments
No full textRelatively little is known of social dynamics in forest elephants (Loxodonta africana cyclotis), although the fission-fusion model of sociality known in savannah elephants (Loxodonta africana africana) is used as a template. Until fission-fusion sociality or an alternative model is demonstrated, our understanding of how elephants use their environment remains incomplete. To date, there have been no published studies of associations between individuals in forest elephants. Direct observations of forest elephants made at forest clearings (bais) are here used as an approach to studying these questions. Bais represent a special environment, providing mineral and food resources, as well as potential social opportunities. We show that forest elephants at Mbeli Bai in Nouabalé-Ndoki National Park have association patterns that are consistent over time, and that certain conspecifics are preferred as associates in the bai environment. Coupled with significant differences in the group size and composition across age-sex classes, and a high proportion of sightings of lone individuals, we argue that the fission-fusion model of elephant sociality appears to hold for the bai environment. The extent of this system and the importance of bais as social resources remain to be explored
Cosmolaelaps subacutiscutus Bai & Wang 2005
No full textCosmolaelaps subacutiscutus Bai & Wang, 2005 Cosmolaelaps subacutiscutus Bai & Wang, 2005: 26. Cosmolaelaps subacutiscutus.— Ren & Guo, 2008: 328; Kazemi & Rajaei, 2013: 80; Moreira et al., 2014: 320; Moreira, 2014: 231. Hypoaspis (Cosmolaelaps) subacutiscutus.— Bai & Ma, 2012: 557. Notes. These two species have been reported from China (Teng, 1982; Bai & Wang, 2005) and Iran (Kavianpour et al., 2011; Soleimani & Joharchi, 2012; Kazemi & Rajaei, 2013). There are apparent similarities between C. acutiscutus, C. subacutiscutus and C. angustiscutatus. Cosmolaelaps angustiscutatus is recognised by several characters including: scimitar-shaped setae on dorsal shield with distinct knob at their base; the presence of abrupt curvature at the level of seta Z 3 on the dorsal shield; and about eight to ten pairs of setae between genital and anal shields (Willmann, 1951; Lapina, 1976; Karg, 1993; Beaulieu, 2009; personal observation of Karg collection specimens, 2014: see above). The abrupt curvature at the level of Z 3 in the dorsal shield, the presence of unpaired dorsal setae, a small inward curve in the lateral margins of the sternal shield (this character was observed in specimens of C. angustiscutatus in Karg collection, Berlin) and the presence of ten pairs of setae between the genital and anal shields could be considered as the main diagnostic characters of C. acutiscutus and C. subacutiscutus (Teng, 1982; Bai & Wang, 2005). Bai & Ma (2012) separated these species only based on dorsal setae length, which are slightly longer in C. subacutiscutus. Except for the unpaired dorsal setae, these characters could be observed in C. angustiscutatus. Our observation of C. brevipedestra as well as other studies such as Strong & Halliday (1994), Faraji & Halliday (2009) and Beaulieu (2009) have shown that the unpaired setae have no taxonomic value for separating species of Gaeolaelaps and Cosmolaelaps. By comparing the descriptions and figures of these species we could find no distinguishing authentic morphological differences, therefore, C. acutiscutus and C. subacutiscutus are suspected to be junior synonyms of C. angustiscutatus.Published as part of Nemati, Alireza & Gwiazdowicz, Dariusz J., 2016, Description of a new species of Cosmolaelaps Berlese and the male of C. brevipedestra (Karg) from Iran, with notes on some other species of Cosmolaelaps Berlese (Acari: Laelapidae), pp. 535-551 in Zootaxa 4066 (5) on page 545, DOI: 10.11646/zootaxa.4066.5.2, http://zenodo.org/record/27056
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

Association of the body adiposity index (BAI) with metabolic risk factors in young and older overweight and obese women.
No full textPURPOSE:
Body adiposity index (BAI) is a novel index for the assessment of percentage fat mass (FM%). We tested the association between BAI and metabolic outcomes in overweight and obese women of different ages.
METHODS:
260 young women (24.7 ± 5.3 years, 31.0 ± 5.0 kg/m(2)) and 328 older women (66.9 ± 4.6 years, 34.8 ± 4.7 kg/m(2)) were recruited. BAI was calculated using hip circumference and height. Bioimpedance analysis was used to measure FM%. Metabolic risk was assessed using a composite z score integrating standardised measurements of fasting glucose, total cholesterol, liver enzymes and triglycerides.
RESULTS:
The association between BAI and FM% was modest in both young (r = 0.56, p < 0.001) and older (r = 0.49, p < 0.001) groups. BAI was directly associated with metabolic risk in young women (r = 0.29, p < 0.001), whereas it showed a weak, inverse association in the older group (r = -0.14, p = 0.01).
CONCLUSIONS:
BAI validity needs to be re-assessed in older individuals for better definition of its predictive accuracy
