Various meaningful generalizations could be obtained after gaining insight into some mathematical assertions from different points of view. Generalizations of two problems from International Mathematical Olympiad papers are shown when the details are combined with the opportunities of the program software „The Geometer’s Sketchpad “ (GSP).

Plutarch wrote twenty-three Greek Lives in his series of Parallel Lives—of these, ten were devoted to Athenians. Since Plutarch shared the hostile view of democracy of Polybius and other Hellenistic Greeks, this Athenian preponderance could have been a problem for him. But Plutarch uses these men’s handling of the democracy and especially the demos as a way of gaining insight into the character and capability of his protagonists. This chapter reviews Plutarch’s attitude to Athenian democracy and examines the way a statesman’s character is illuminated by his interaction with the demos. It also considers what it was about Phocion that so appealed to Plutarch, first by looking at his relationship with the democracy and then at the way he evokes the memory of Socrates. For him this was not a minor figure, but a man whose life was representative of the problems of Athenian democracy.

The genus Elaeocarpus is the largest genus in the family Elaeocarpaceae, comprising more than 350 species of trees and shrubs with a mainly Indo-Pacific distribution. Approximately 28 species in the genus, including nine species from Australia, are known to possess ruminate endosperm. To provide a basis for understanding fruit development and endosperm rumination in the genus and, therefore, its taxonomic and evolutionary significance, we studied the fruit anatomy of Elaeocarpus ruminatus F.Muell. at different developmental phases (petal-fall to maturity). We found lignin in pericarp and ovary wall tissues in the earliest stages of development. In contrast, endosperm rumination occurs only after fruits have fully expanded, and becomes more pronounced as fruits ripen. Its phylogenetic distribution suggests that ruminate endosperm is a derived, albeit homoplasious character in Elaeocarpus. Comparative studies on related species will be instructive in determining the utility of ruminate endosperm for informing infra-generic taxonomy of the genus, and gaining insight into its adaptive significance.

Web link mining has been previously used as a way of gaining insight into how the Internet may be replicating or reshaping connections between institutions within the higher education sector. Institutions are increasingly active on social media platforms, and these connections have not been studied. This paper presents an exploratory analysis of the network of UK higher education institutional accounts on Twitter. All U.K. institutions have a presence. Standing in recent university rankings is found to be a significant predictor of several network metrics. In examining the communities present within the network, a combination of ranking and geolocation play a role. Analysis of a sample of tweets which mention more than one U.K. higher education institution provides an indication of why the topics of tweets would reinforce prestige and location in the network structure.

Due to asynchronous development, gifted children often experience the world differently than their same-aged peers. Some experience unique intensities, or overexcitabilities, that render modifications in teaching and parenting. These intensities typically take on characteristics of emotional, intellectual, imagination, psychomotor, or sensual overexcitability. In this in-depth interview study, I explored parent perceptions of intensity in their gifted adolescent children. Three mothers participated and completed the Overexcitability Inventory for Parents-Two (OIP-II) prior to each interview. The parent responses to the OIP-II served as an elicitation device to begin our conversations. Thematic analysis revealed three main themes among the participants’ perceptions: (1) challenging behaviors of intense gifted children, (2) consequences of intensity, and (3) a parent’s search for understanding. These findings inform the understanding of intensity and overexcitability from parents’ points of view and provide insight into how intense gifted children behave outside of the classroom. I conclude the article with questions to consider regarding how to better support parents of young gifted children.

Psoriasis affects the health of myriad populations around the world. The pathogenesis is multifactorial, and the exact driving factor remains unclear. This condition arises from the interaction between hyperproliferative keratinocytes and infiltrating immune cells, with poor prognosis and high recurrence. Better clinical treatments remain to be explored. There is much evidence that alterations in the skin and intestinal microbiome play an important role in the pathogenesis of psoriasis, and restoration of the microbiome is a promising preventive and therapeutic strategy for psoriasis. Herein, we have reviewed recent studies on the psoriasis-related microbiome in an attempt to confidently identify the “core” microbiome of psoriasis patients, understand the role of microbiome in the pathogenesis of psoriasis, and explore new therapeutic strategies for psoriasis through microbial intervention.
