This species was erected based on both complete forewings and hind wings (Wang & Ren, 2007 a). After re-examining part and counterpart of the holotype, we have reconstructed the hind wing of Q. fangi (Fig. 3). Sc and R are similar to those of Q. eumorphus: Sc parallel with R at base, fused with R at point of origin of Rs, then confluent with R 1 + 2 for short interval, then extended to costal margin at indentation.Published as part of Wang, Ying, Wang, Lin & Ren, Dong, 2008, Revision of genera Quadraticossus, Martynovocossus and Fletcheriana (Insecta, Hemiptera) from the Middle Jurassic of China with description of a new species, pp. 56-64 in Zootaxa 1855 on page 59, DOI: 10.5281/zenodo.18352

Distribution. Taiwan. Etymology. The specific name felix is Latin for happy, lucky, fortunate. Biology. Aprostocetus felix is a solitary parasitoid collected from mature larvae and pupae of Q. erythrinae. In contrast to other parasitoids found on Q. erythrinae in the early stage of the pest invasion, population levels of this species remain high in cooler times of the year when other parasitoid population levels declined. Its population levels have built up through the years and it now occurs all year round in most areas in Taiwan, where it appears to have the potential to be an effective biological control agent of Q. erythrinae (Yang & Lin, unpublished).Published as part of Yang, Man-Miao, Lin, Yu-Che, Wu, Yaojun, Fisher, Nicole, Saimanee, Titiporn, Sangtongpraow, Benjakhun, Zhu, Chaodong, Chiu, William Chien-Hsien & Salle, John La, 2014, Two new Aprostocetus species (Hymenoptera: Eulophidae: Tetrastichinae), fortuitous parasitoids of invasive eulophid gall inducers (Tetrastichinae) on Eucalyptus and Erythrina, pp. 261-272 in Zootaxa 3846 (2) on pages 266-269, DOI: 10.11646/zootaxa.3846.2.6, http://zenodo.org/record/492857

Religious pathways to coping with personal death anxiety among older adult British Christians and Chinese Buddhists: afterlife beliefs, psychosocial maturity and regret management
No full textReligion was proposed to account for the relatively low personal death anxiety found among older adults. This dissertation sought to examine the influence of religious afterlife beliefs, religiously enhanced psychosocial maturity and religious management of a past major regret on personal death anxiety in later life. Terror Management Theory and Erikson’s Psychosocial Theory were used to describe these three religious pathways to coping with personal death anxiety in later life. The cross-sectional postal survey samples consisted of 143 older adult British Christians and 141 older adult Chinese Buddhists. Structural Equation Modelling results from the British Christian survey study showed that intrinsic religiosity predicted lower personal death anxiety through: (a) fostering more benign afterlife beliefs; (b) enhancing psychosocial maturity; and (c) promoting emotional stability. No significant relationship between belief in reincarnation and personal death anxiety was found in the Chinese Buddhist survey study. Both survey studies failed to support the personal death anxiety buffering power of religious management of a past major life regret, although some religious coping strategies were associated with lower negative emotional appraisal towards the major life regret among older adults. The British survey study has been the first to demonstrate both the personal death anxiety buffering and psychosocial maturity enhancing power of religion in an increasingly secular society. The lack of relationship between Buddhist reincarnation beliefs and personal death anxiety suggests that not all religious afterlife beliefs have death anxiety buffering power as proposed by Terror Management Theory. The development of Buddhist reincarnation belief and Buddhist coping scales is a pioneering step towards developing research on under-explored Eastern non-theistic afterlife beliefs and coping measures. Implications for ways that help religious older adults cope with their personal death anxiety were discussed. Prospective cross cultural and cross-religion studies were recommended to replicate the present survey findings. Finally, self detachment (self negation) was proposed as the basis of an alternative death transcendence theory to be researched in future studies on personal death anxiety
