This is a continuation of a study on Riemann theta function representations of algebro-geometric solutions to soliton hierarchies. In this part, we straighten out all flows in soliton hierarchies ...under the Abel–Jacobi coordinates associated with Lax pairs, upon determining the Riemann theta function representations of the Baker–Akhiezer functions, and generate algebro-geometric solutions to soliton hierarchies in terms of the Riemann theta functions, through observing asymptotic behaviours of the Baker–Akhiezer functions. We emphasize that we analyse the four-component AKNS soliton hierarchy in such a way that it leads to a general theory of trigonal curves applicable to construction of algebro-geometric solutions of an arbitrary soliton hierarchy.
Invasion genetics is a relatively new discipline that investigates patterns of genetic variation in populations of invasive species and their ecological and evolutionary consequences. Evolutionary ...biologists have a long‐standing interest in colonizing species, owing to their short life cycles and widespread distributions, but not until publication of The Genetics of Colonizing Species (1965), edited by H.G. Baker and G.L. Stebbins, was a synthesis on the genetics and evolution of colonizers available. Here, I make the case that the Baker and Stebbins volume is the foundational document for invasion genetics, and in conjunction with the increased use of genetic markers and development of invasion biology, resulted in the birth of this new field over the past two decades. I consider the historical origins and legacy of the Baker and Stebbins volume and review some of the key issues that were addressed. I provide biographical sketches of the two editors, emphasizing their contrasting backgrounds and personalities. I review examples from my own work on plant invasions that are relevant to issues discussed by contributors to the volume. These include the following: determinants of invasion success, life history trade‐offs, generalist vs. specialist strategies, general‐purpose genotypes, adaptive phenotypic plasticity, mating systems and the influence of bottlenecks on genetic variation. I conclude by posing several key questions in invasion genetics and argue that one of the main challenges that the area faces is to integrate experimental field studies of the ecology and demography of populations with the largely descriptive approaches that have tended to dominate most research to date.

Chronic pain is a difficult condition to define that exists in a grey area in medicine where subjectivity and objectivity blend. Infinite Life focuses on the difficulty of sharing the experience of ...chronic pain with others and how this issue can deepen a person's sense of isolation. ...the breast cancer has now returned so Yvette is back to try fasting again before she will agree to undergo a double mastectomy and chemotherapy. ...it is in Sofi's physical touch to ease Eileen's pain in her legs for a moment that the ephemeral bridge between two individuals appears for a moment.

Ella Baker (1903-1986) was an influential African American civil
rights and human rights activist. For five decades, she worked
behind the scenes with people in vulnerable communities to catalyze
...social justice leadership. Her steadfast belief in the power of
ordinary people to create change continues to inspire social
justice activists around the world. This book describes a case
study that translates Ella Baker's community engagement philosophy
into a catalytic leadership praxis, which others can adapt for
their work. Catalytic leadership is a concrete set of communication
practices for social justice leadership produced in equitable
partnership with , instead of on , communities. The
case centers the voices of African American teenage girls who were
living in a segregated neighborhood of an affluent college town and
became part of a small collective of college students, parents,
university faculty, and community activists learning leadership in
the spirit of Ella Baker.
Jacques Derrida’s theory of deconstruction provides an ideal means of appreciating and interrogating the duality central to both Robert Louis Stevenson’s Strange Case of Dr Jekyll and Mr Hyde and its ...adaptations. Moreover, because deconstruction exposes binary oppositions as artificial and constrictive, it enables us to advance beyond them toward multiplicity, a term used by Gilles Deleuze for a complex, ever-changing, multipart structure that transcends unity. Roy Ward Baker’s Dr Jekyll and Sister Hyde (1971) and episodes of Showtime’s Penny Dreadful (2014–2016) offer fresh ways to think about—and beyond—the duality of culture’s most famously divided pair. The binary oppositions that organize each text are innovative, as are the ways in which these oppositions are reversed and conflated. Ultimately, these adaptations employ triangulation to deconstruct themselves, thereby demonstrating the limitations and instability of duality, as well as the possibilities of multiplicity.
