Abstract: High performance level in face recognition studies does not seem to be replicable in real-life situations possibly because of the artificial nature of laboratory studies. Recognizing faces in natural social situations may be a more challenging task, as it involves constant examination of dynamic facial motions that may alter facial structure vital to the recognition of unfamiliar faces. Because of the incongruences of recognition performance, the current study developed stimuli that closely represent natural social situations to yield results that more accurately reflect observers’ performance in real-life settings. Naturalistic stimuli of African, East Asian, and Western Caucasian actors introducing themselves were presented to investigate Malaysian Chinese participants’ recognition sensitivity and looking strategies when performing a face recognition task. When perceiving dynamic facial stimuli, participants fixated most on the nose, followed by the mouth then the eyes. Focusing on the nose may have enabled participants to gain a more holistic view of actors’ facial and head movements, which proved to be beneficial in recognizing identities. Participants recognized all three races of faces equally well. The current results, which differed from a previous static face recognition study, may be a more accurate reflection of observers’ recognition abilities and looking strategies.

Abstract: Decades of research have fostered the now-prevalent assumption that noncrop habitat facilitates better pest suppression by providing shelter and food resources to the predators and parasitoids of crop pests. Based on our analysis of the largest pest-control database of its kind, noncrop habitat surrounding farm fields does affect multiple dimensions of pest control, but the actual responses of pests and enemies are highly variable across geographies and cropping systems. Because noncrop habitat often does not enhance biological control, more information about local farming contexts is needed before habitat conservation can be recommended as a viable pest-suppression strategy. Consequently, when pest control does not benefit from noncrop vegetation, farms will need to be carefully comanaged for competing conservation and production objectives.

Abstract: Human land use threatens global bio ersity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by few abundant species or rely on high richness remains unclear. Using a global database from 89 crop systems, we partition the relative importance of abundance and species richness for pollination, biological pest control and final yields in the context of on-going land-use change. Pollinator and enemy richness directly supported ecosystem services independent of abundance. Up to 50% of the negative effects of landscape simplification on ecosystem services was due to richness losses of service-providing organisms, with negative consequences for crop yields. Maintaining the bio ersity of ecosystem service providers is therefore vital to sustain the flow of key agroecosystem benefits to society.

Abstract: This paper reviewed articles on autobiographical memories of veterans who fought several major battles around the world. A total of 28 articles, reporting 11 quantitative, 16 qualitative, and 1 mixed-methods study, were identified through a search conducted in 11 major databases. Convergent thematic analysis of the findings extracted five recurrent themes: (1) memory features, (2) memory content, (3) self and memory, (4) culture and memory, and (5) theoretical accounts. Veterans’ memories were mostly aligned with the hegemonic narratives, although many of them were the depiction of atrocities (theme 1). Veterans with post-traumatic stress disorder and other mental disorders recalled less specific and less coherent autobiographical memories (theme 2) their retrieval was influenced by split identity—combatant versus veteran identity, generational identity, and political ideology (theme 3). War outcome, dominant public narratives, political environment, and myths prevailing in the society influenced the memory recall (theme 4). While qualitative studies used Erickson’s identity theory to explain how personal identity in conjunction with social identity helped to construct veterans’ memories, quantitative studies used Car-Fa-X model to explain why veterans with various mental health conditions predominantly produced overgeneral memories (theme 5). Findings are discussed through the current theories of autobiographical memory.
