No full textFor everything there was a season: phenological shifts within the flora of the Tetons
No full textAround the world, phenology — the timing of ecological events — is shifting as the climate warms. This can lead to a variety of consequences for individual species and entire ecological communities, most notably when asynchronies develop between plants and animals that depend upon each other (e.g. nectar-consuming pollinators). Grand Teton National Park biologists have identified this topic (“effect of earlier plant flowering on pollinators and wildlife”) as one of their priority research needs. We have gathered, digitized, and quality-controlled phenological observations of first flowering dates collected by Frank Craighead, Jr. in the 1970s, before significant warming occurred. First flowering date for 87% of a 72-species data set correlates significantly with spring temperatures in the 1970s, suggesting that these plants should now be flowering earlier and will continue to flower earlier in the future. This year we began standardized phenological observations of these 72 species in the same location and initiated a citizen science program. Our proposed next steps are to: (1) gather and analyze further historical records of plant phenology; (2) conduct 3-5 additional years of contemporary observations; (3) link plant phenological changes with potential cascading impacts on pollinators and foragers; (4) model phenology under future climate change scenarios; and (5) implement a long-term citizen science program in the Tetons.

Beaver and state transition in Yellowstone
No full textExtirpation of wolves from the Greater Yellowstone Ecosystem (GYE) in the 1920shypothetically triggered a behaviorally-mediated trophic cascade in which elk (Cervus elaphus), released from the fear of wolf (Canis lupus) predation, over-browsed riparian zones. Eventually, vast areas of meadow-wetland complexes transitioned to grass-lodgepole systems. The importance of beaver (Castor canadensis) in wetland losses has received less attention. Beaver abandoned most of the GYE by the 1950s, possibly due to resource limitations. Researchers from Colorado State University established an experimental system for Long Term Environmental Research in Biology (LTREB) along several streams in the Lamar Valley of Yellowstone sixteen years ago. To evaluate effects of hydrologic changes and elk browsing on productivity of willows (Salix spp.) and state transition, they built small experimental dams with browsing exclosures. In 2015, beaver began recolonizing the region. I am investigating how their biologic as well as hydrologic impacts affect the underlying mechanisms of state transition: nutrient cycling, productivity, and stream respiration. I posit that beaver are keystone species, meaning that the sustained recovery of wetland-meadow complexes is unlikely without the higher levels of riparian productivity triggered by the biological influence of beaver.

Inverses of bicyclic graphs
No full textA graph G is said to be nonsingular (resp., singular) if its adjacency matrix A(G) is nonsingular (resp., singular). The inverse of a nonsingular graph G is the unique weighted graph whose adjacency matrix is similar to the inverse of the adjacency matrix A(G) via a diagonal matrix of ±1s. Consider connected bipartite graphs with unique perfect matchings such that the graph obtained by contracting all matching edges is also bipartite. In [C.D. Godsil. Inverses of trees. Combinatorica, 5(1):33â39, 1985.], Godsil proved that such graphs are invertible. He posed the question of characterizing the bipartite graphs with unique perfect matchings possessing inverses. In this article, Godsilâs question for the class of bicyclic graphs is answered
On the inverse of a class of weighted graphs
No full textIn this article, only connected bipartite graphs with a unique perfect matching are considered. Let G_\w denote the weighted graph obtained from by giving weights to its edges using the positive weight function \w:E(G)\ar (0,\ity) such that \w(e)=1 for each . An unweighted graph may be viewed as a weighted graph with the weight function \w\equiv\1 (all ones vector). A weighted graph G_\w is nonsingular if its adjacency matrix A(G_\w) is nonsingular. The {\em inverse} of a nonsingular weighted graph G_\w is the unique weighted graph whose adjacency matrix is similar to the inverse of the adjacency matrix A(G_\w) via a diagonal matrix whose diagonal entries are either or . In [S.K.~Panda and S.~Pati. On some graphs which possess inverses. {\em Linear and Multilinear Algebra}, 64:1445--1459, 2016.], the authors characterized a class of bipartite graphs with a unique perfect matching such that is invertible. That class is denoted by . It is natural to ask whether G_\w is invertible for each invertible graph and for each weight function \w\not\equiv\1. In this article, first an example is given to show that there is an invertible graph and a weight function\w\not\equiv\1 such that G_\w is not invertible. Then the weight functions \w for each graph such that G_\w is invertible, are characterized
The Fix We Are In
No full textI have been thinking about the history and future of the labor movement for fifty years. As an academic in philosophy I have focused my research on the intersections of the global labor movement with philosophy of history, philosophy of science, ethics, economics, and political theory. ‘The Fix We Are In’ is a summary of my current thinking. At present the grand strategies for emancipation, ascendant in the mid-twentieth century, have faltered. Headless capitalism runs amuck. The conditions of the working class deteriorate. There is no vision of a better world—no clear pathway toward a better future. The ‘popular revolt’ bubbling up around the globe is a product of this moment. My paper concludes with a difficulty regarding my own favored way forward. Responses from readers would be welcome at: [email protected]

No full textInsider Without: Journey across the Working-Class Academic Arc
No full textPatricia Hill Collins (1986) labels herself as an ‘outsider within’ due to her intersectional standpoint as a Black woman sociology professor in the ivory tower. In contrast to the ‘outsider within’ lens, I theorize my own social location as an ‘insider without’ due to a complex matrix of identities within the classed academic cultural context. Using counter storytelling, I explore my insider without location through analysis of my journey across the ‘working-class academic arc.’ In the working-class academic arc described below, I apply intersectional theory (Collins 1990; Crenshaw 1989) by connecting my personal experiences with existing working-class studies scholarship. The arc process culminates in my development of critical intersectional class consciousness and actions of resistance. By introducing this three-phase arc, I hope to raise awareness of the invisible academic class culture which invalidates working-class ways of being and knowledge production
The Poverty of Academia: My Life as NonTenure Track Faculty
No full textNon-tenure track (NTT) positions include faculty who teach full and part-time and are not on the tenure-track. These positions include full-time lecturers, fixed-term faculty, etc. Positions such as these are typically on one-year contracts, though some may be on 1 - 3 year contracts. While the title, pay and status, among other things, varies by institutions, it is undeniable that universities and colleges have been shifting in recent years to this kind of contingent labor force. These positions also include part-time adjuncts including professionals teaching a class here and there, and professional teachers who may teach at many institutions. Individuals who are not on the tenure-track often find themselves with little job security, an often inequitable distribution of labor (in terms of class preps, class size, etc.), and in positions that pay significantly less than their tenure-track counterparts’ salaries
