Amsinckia hispida is a serious annual weed of cereal culture in north-western Victoria. Individual plants produce seed for up to two months in the spring and this provides a range of seed maturity that is reflected by a gradual build-up of germinability in the following autumn. In addition the seed has an optimum constant temperature for germination of 13�C (48�F) and responds markedly to a period of cold treatment. These three features act together to produce the series of Amsinckia populations which are characteristic of its autumn germination behaviour in north-west Victoria. Seeds which germinate early are responsible for infestations in the pasture phase and those which germinate later are not controlled by pre-sowing cultivation and remain to germinate within crops. The response of Amsinckia to environmental factors is such that these plants which germinate late within wheat crops have an extended rosette period and are highly competitive.

This study examined the political and environmental factors as determinants to apply forensic accounting in the North-Western states of Nigeria. The study utilized primary data through the administration of questionnaires. Partial least squares (PLS) path modeling (using smart PLS3 statistical software) was employed for the main analysis. The findings of the study indicated that both political and environmental factors are positively related to applying forensic accounting in these states. The study recommended that all political office holders and other government personnel should, even with the change of government, use their powers to ensure the right way to move forward and the continuity of state policies to apply forensic accounting. State governments should also provide an enabling environment for the applicability of forensic accounting through the provision of the required infrastructure to carry out the forensic services smoothly.

Abstract. We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the species-level analysis more clearly distinguishes among forests. Next, we compared the variation in plot floristic composition at regional- and continental-scales, and found that average among-pair floristic similarity and its decay with distance behave similarly at regional- and continental-scales. Nevertheless, geographical distance had different effects on floristic similarity within regions at distances <100 km, where north-western and south-western Amazonian regions showed greater floristic variation than plots of central and eastern Amazonia. Finally, we quantified the role of environmental factors and geographical distance for determining variation in floristic composition. A partial Mantel test indicated that while geographical distance appeared to be more important at continental scales, soil fertility was crucial at regional scales within western Amazonia, where areas with similar soil conditions were more likely to share a high number of species. Overall, these results suggest that regional-scale variation in floristic composition can rival continental-scale differences within Amazonian terra firme forests, and that variation in floristic composition at both scales is influenced by geographical distance and environmental factors, such as climate and soil fertility. To fully account for regional-scale variation in continental studies of floristic composition, future floristic studies should focus on forest types poorly represented at regional scales in current datasets, such as terra firme forests with high soil fertility in north-western Amazonia.

Abstract Empirical research into social vulnerability – and into strategies that allow people to persist or secure their existence – has most often concerned itself with peripheral, poorly-developed regions with a long history of shortages; frequently even ones in which a failure to solve socio-political problems over decades or even centuries, manifests itself in a permanent crisis. One such region is north–western Peru, presented in this article by the authors who have proceeded on the assumption that the socioeconomic development of the country’s mountainous areas (including Frías, the district selected for study) not only reflects a peripheral location as regards central areas of Peru and the department of Piura, but is also an outcome of the workings of political and environmental factors that do not help sustain (or in many cases even obstruct) processes of development.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.

Formal articulation test responses are often used by the busy clinician as a basis for planning intervention goals. This article describes a 6-step procedure for using efficiently the single-word responses elicited with an articulation test. This procedure involves the assessment of all consonants within a word rather than only test-target consonants. Responses are organized within a Model and Replica chart to yield information about an individual's (a) articulation ability, (b) frequency of target attainment, substitutions, and deletions, (c) variability in production, and (d) phonological processes. This procedure is recommended as a preliminary assessment measure. It is advised that more detailed analysis of continuous speech be undertaken in conjunction with early treatment sessions.

The World Health Organization's (WHO's) 2001 International Classification of Functioning Disability and Health (ICF) has as one of its central tenets the full inclusion of persons with disabilities in society. It acknowledges the need for medical and rehabilitation intervention in its biopscychosocial framework. However, the WHO realizes that society must do its part to facilitate this full participation and empowerment. Persons with complex communication needs (PWCCN) often need augmentative and alternative communication (AAC) in order to express themselves. However, in order to access and successfully use AAC, PWCCN need access to the necessary AAC devices and services, as well as a willing society to interact with them as full contributing members of society. The factors outside of a person's specific physical and/or cognitive functional limitations are addressed in the ICF via the Personal and Environmental Factors. Personal Factors include the individual's personality traits, lifestyle, experiences, social/educational/professional background, race, gender, and age. Environmental Factors include community support systems, social service agencies, governments, social networks, and those persons that interact with the PWCCN. This article addresses the sociopolitical influences on PWCCN and their functioning from a human rights perspective. The necessary introspective role of speech-language pathologists in this process is explored.
