Abstract: Lepidosperma prospectum G.T.Plunkett & R.L.Barrett (Cyperaceae tribe Schoeneae) is here described as a new species in the Sydney region of New South Wales. It is highly restricted in distribution, occurring at Manly (Sydney Harbour National Park), Kamay Botany Bay National Park and Royal National Park in dense coastal shrublands behind coastal cliffs. These locations are within the traditional lands of the Gamaragal, Gweagal and Dharawal people respectively. Joseph Banks and Daniel Solander were the first Europeans to explore the flora of New South Wales in 1770 around Botany Bay but they did not collect this species. Lepidosperma prospectum is superficially similar to L. sieberi Kunth, which occurs in adjacent habitats, but molecular data have shown that it is more closely allied to Western Australian species. A brief review of recorded indigenous and European knowledge and utilisation of the genus Lepidosperma Labill. is presented to highlight the varied uses of the genus.

Abstract: An intellectual disability (ID) is characterized by a deficit in the functional, cognitive, and adaptive skills required for independent living. Due to the low cognitive capabilities of in iduals with IDs, they have become victims of marginalization, exclusion, and denial of their fundamental rights to basic necessities in societies around the world. While efforts are being made to improve service provision to and acceptance of in iduals with disabilities, the extent of communal acceptance and recognition of these in iduals as equal members of society remains underexplored in sub-Saharan African countries such as Cameroon and Ghana. As attitudes toward in iduals with IDs are pivotal in shaping national policies, this cross-national study examined communal attitudes toward persons with IDs in Cameroon and Ghana. The Community Living Attitude Scale for Intellectual Disabilities (CLAS-ID) was used to collect data from a total of 741 university students in the two countries. The validity of the scale was assessed using confirmatory factor analysis and principal component analysis. The association between the background variables and attitudes was examined using t-tests, analysis of variance, linear regression, and two-way factor analysis. The results showed the validity of the CLAS-ID as a valid tool for measuring communal attitudes toward in iduals with IDs in sub-Saharan Africa. The participants appeared ambivalent about attitude towards in iduals with ID and other findings showed no association between attitudes and variables such as gender, relation, and contact with in iduals with IDs. We discuss the need for innovative approaches aimed at changing attitudes toward in iduals with IDs in sub-Saharan Africa as well as other study implications.

Abstract: Deplorable living conditions among persons with disabilities and the need to improve their living conditions cannot be overemphasized. This has triggered international discussion on the need for deliberate social policies to bridge the poverty gap between persons with and without disabilities. In Malawi, expansion of financial services has been identified as an essential tool to accelerate economic and inclusive development. However, empirical studies are yet to explore the preparedness of financial institutions to extend their services to persons with disabilities. In this qualitative study, semi-structured interviews were conducted with managers from commercial banks in Malawi to understand their perspectives on extending financial services to persons with disabilities. Interviews were transcribed verbatim and a descriptive thematic analysis was performed. Although participants reiterated the need to provide persons with disabilities with financial services to improve their well-being, few initiatives have been undertaken to improve their participation. Particularly, participants stated that barriers, such as a lack of financial literacy and adaptive technologies, communication barriers, and high rates of unemployment, explained the reluctance of commercial banks to extend financial services to persons with disabilities. The limitations, recommendations for future research, and implications of the study for policymaking have been highlighted.

Abstract: In the framework of the competitive electricity markets, electricity price forecasting is important for market participants in a deregulated electricity market. Rather than forecasting the value, market participants are sometimes more interested interval of the peak electricity price forecasting. Forecasting the peak price is essential for estimating the uncertainty involved in the price and thus is highly useful for making generation bidding strategies and investment decisions. The choice of the forecasting model becomes the important influence factor how to improve price forecasting accuracy. This paper proposes new approach to reduce the prediction error at occurrence time of the peak electricity price, and aims to enhance the accuracy of the next day electricity price forecasting. In the proposed method, the weekly variation data is used for input factors of the ANN at occurrence time of the peak electricity price in order to catch the price variation. Moreover, learning data for the ANN is selected by rough sets theory at occurrence time of the peak electricity price. This method is examined by using the data of the PJM electricity market. From the simulation results, it is observed that the proposed method provides a more accurate and effective forecasting, which helpful for suitable bidding strategy and risk management tool for market participants in a deregulated electricity market.

Abstract: The diaspores of Lepidosperma Labill. (Cyperaceae) have thickened perianth members persistent at the base of the fruit, which are generally assumed to form a unique type of elaiosome but this assumption has not been tested rigorously. We tested whether the perianth provides a lipid-rich food reward and improves diaspore removal by ants in three species of Lepidosperma. We measured (i) the lipid and fatty acid composition of the fruit and perianth of two species of Lepidosperma, and of the seed and aril of two species of Acacia (known myrmecochores), (ii) the relative attractiveness to ants of the perianth in three species of Lepidosperma, and (iii) the relative attractiveness to ants of the diaspores of the same species of Lepidosperma compared with the two species of Acacia. We found that (i) Lepidosperma diaspores show traits consistent with myrmecochory, particularly the high lipid content (∼12–60%) and fatty acid profile of perianth material, (ii) isolated perianth members were removed in greater numbers over all times than were diaspores only (i.e. with perianth removed) in two species of Lepidosperma (n = 100, P = 0.035 and 0.047), whereas the difference was equivocal in the third species (n = 100, P 0.05), and (iii) Lepidosperma and Acacia diaspores were removed in similar numbers over time (n = 100, P 0.5). Seven species of diaspore-removing ant were observed, with Rhytidoponera metallica accounting for ∼50% of observed removals. We conclude that the perianth members of Lepidosperma are an elaiosome that provides a lipid-rich food reward.

Abstract: We investigated the limits of Lepidosperma congestum R.Br. and a putative new species of Lepidosperma Labill. from Victoria and South Australia. Phenetic analyses (flexible UPGMA agglomerative hierarchical fusion and semi-strong hybrid multidimensional scaling) were conducted on a dataset derived from morphological characters scored from herbarium material. The results of our analyses supported the recognition of a new species, which we describe here as Lepidosperma hispidulum G.T.Plunkett, J.J.Bruhl & K.L.Wilson. Our results clarified the differences among L. congestum, L. laeve R.Br. and L. hispidulum, the first two of which have often been misidentified. We also discuss the distribution, habitat and conservation status of L. hispidulum.
