Drainage of Land Overlying an Artesian Aquifer: Logan-Cache Airport

Drainage problem Logan-Cache Airport is situated approximately 4 miles northwest of Logan, Utah, in sections 8, 9, 16, and 17, Township 12 north, Range 1 east, of Salt Lake Base and Meridian. The area of approximately 200 acres is a part of what is known as cache County Drainage District No.2. This district in itself contains more than 8,400 acres of waterlogged lands. Drainage of the se lands has, for many years, been a baffling and unsolved problem, complicated by 3 factors: (a) The whole of the valley in this area is underlain by an artesian ground-water reservoir. (b) The artesian aquifer is overlain by a layer of heavy clay of very lo~ permeability, ranging in depth from 40 to 70 feet. (c) Human relations with farmers within the area , who consider that drainage will deprive them of their plentiful groundwater Supply

Work in Progress - Designing for Economic Empowerment in Nicaragua

Faculty and students in several disciplines at four institutions in the United States and Nicaragua are collaborating on technology entrepreneurship education for economic empowerment in Esteli, Nicaragua. The project aims to demonstrate a new paradigm for development that is rooted in education. The effort will focus on design and delivery of new curriculum for collaborative, interdisciplinary product development. To demonstrate the curriculum, the effort will launch cross-cultural student teams to identify and develop markets, partners, and technology for entrepreneurial ventures in Nicaragua, utilizing Nicaraguan materials and skills. The envisioned long term goal is local economic empowerment and a sound, collaborative process for technology innovation and product development that is both replicable and transferable. The proposed program includes six sequential phases; phase one is complete and phase two is in progress. This paper discusses the goals, results, and assessment of the first two phases in the context of the ongoing project

Do well managed firms make better forecasts?

We link a new UK management survey covering 8,000 firms to panel data on productivity in manufacturing and services. There is a large variation in management practices, which are highly correlated with productivity, profitability and size. Uniquely, the survey collects firms' micro forecasts of their own sales and also macro forecasts of GDP. We find that better managed firms make more accurate micro and macro forecasts, even after controlling for their size, age, industry and many other factors. We also show better managed firms appear aware that their forecasts are more accurate, with lower subjective uncertainty around central values. These stylized facts suggest that one reason for the superior performance of better managed firms is that they knowingly make more accurate forecasts, enabling them to make superior operational and strategic choices

Climate oscillations, glacial refugia, and dispersal ability: factors influencing the genetic structure of the least salmonfly, Pteronarcella badia (Plecoptera), in Western North America

Background: Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested hypotheses related to mode of dispersal and the influence of historic climate oscillations on population genetic structure. In order to generate a larger mitochondrial data set, we used 454 sequencing to reconstruct the complete mitochondrial genome in the early stages of the project. Results: Our analysis revealed high levels of population structure with several deeply divergent clades present across the sample area. Evidence from five mitochondrial genes and one nuclear locus identified a potentially cryptic lineage in the Pacific Northwest. Gene flow estimates and geographic clade distributions suggest that overland flight during the winged adult stage is an important dispersal mechanism for this taxon. We found evidence of multiple glacial refugia across the species distribution and signs of secondary contact within and among major clades. Conclusions: This study provides a basis for future studies of aquatic insect phylogeography at the inter-basin scale in western North America. Our findings add to an understanding of the role of historical climate isolations in shaping assemblages of aquatic insects in this region. We identified several geographic areas that may have historical importance for other aquatic organisms with similar distributions and dispersal strategies as P. badia. This work adds to the ever-growing list of studies that highlight the potential of next-generation DNA sequencing in a phylogenetic context to improve molecular data sets from understudied groups

Incest in the 1990s: reading Anais Nin's 'Father Story'

In the summer of 1933, diarist, author and critic Anaïs Nin joined her father for a short vacation in France. Nin wrote about the trip in her diary afterwards, referring to it as the ‘Father Story.’ In the story, she details how, aged 30, she embarked upon an affair with her father which would last for several months. Rather than displaying the signs of trauma that we have come to expect from the incest narrative such as dissociation, blame and recrimination, the ‘Father Story’ is more ambiguous in its tone. Part-tribute to the father, part-seduction narrative, part-confession, this is a story that resists categorisation – a resistance that has ethical, critical and formal ramifications for our reading of incest narratives. Upon its publication in the early 1990s, critics responded to the ‘Father Story’ as fantastical, excessive and vulgar. These responses form part of a wider American father story during this period; a story about memory, therapy culture, family values and the concealed rules of testimony. This article reads Anaïs Nin’s narrative as a text which raises fundamental questions about why certain father (and daughter) stories are culturally acceptable and others are not

Extinction vortex dynamics of top predators isolated by urbanization

Extinction risk is elevated in small, isolated populations due to demographic and genetic interactions. Therefore, it is critical to model these processes realistically in population viability analyses (PVA) to inform local management and contribute to a greater understanding of mechanisms within the extinction vortex. We conducted PVA’s for two small mountain lion populations isolated by urbanization in southern California to predict population growth, extinction probability, and loss of genetic diversity with empirical data. Specifically, we (1) provide the first PVA for isolated mountain lions in the Santa Ana Mountains (SAM) that considers both demographic and genetic risk factors and (2) test the hypothesis that variation in abundance and mortality between the SAM and Santa Monica Mountains (SMM) result in differences in population growth, loss of heterozygosity, and extinction probability. Our models predicted 16–21% probability of local extinction in the SAM due purely to demographic processes over 50 yr with current low levels or no immigration. Our models also predicted that genetic diversity will further erode in the SAM such that concern regarding inbreeding depression is warranted unless gene flow is increased, and that if inbreeding depression occurs, rapid local extinction will be highly likely. Dynamics of the two populations were broadly similar, but they also exhibited differences driven by larger population size and higher mortality in the SAM. Density-independent scenarios predicted a rapidly increasing population in the SMM, whereas growth potential did not differ from a stable trend in the SAM. Demographic extinction probability and loss of heterozygosity were greater in the SMM for density-dependent scenarios without immigration. However, higher levels of immigration had stronger, positive influences on both demographic viability and retention of genetic diversity in the SMM driven by lower abundance and higher adult survival. Our results elucidate demographic and genetic threats to small populations within the extinction vortex, and how these vary relative to demographic structure. Importantly, simulating seemingly attainable increases in connectivity was sufficient to greatly reduce extinction probability. Our work highlights that conservation of large carnivores is achievable within urbanized landscapes, but requires land protection, connectivity, and strategies to promote coexistence with humans

Loss of Prox1

Correct regulation of troponin and myosin contractile protein gene isoforms is a critical determinant of cardiac and skeletal striated muscle development and function, with misexpression frequently associated with impaired contractility or disease. Here we reveal a novel requirement for Prospero-related homeobox factor 1 (Prox1) during mouse heart development in the direct transcriptional repression of the fast-twitch skeletal muscle genes troponin T3, troponin I2, and myosin light chain 1. A proportion of cardiac-specific Prox1 knockout mice survive beyond birth with hearts characterized by marked overexpression of fast-twitch genes and postnatal development of a fatal dilated cardiomyopathy. Through conditional knockout of Prox1 from skeletal muscle, we demonstrate a conserved requirement for Prox1 in the repression of troponin T3, troponin I2, and myosin light chain 1 between cardiac and slow-twitch skeletal muscle and establish Prox1 ablation as sufficient to cause a switch from a slow- to fast-twitch muscle phenotype. Our study identifies conserved roles for Prox1 between cardiac and skeletal muscle, specifically implicated in slow-twitch fiber-type specification, function, and cardiomyopathic disease
