Three Heads Are Better Than One: Organizational Changes in Collection Management Leadership

Financial pressures, shrinking staff, shifting user expectations, and advances in format access and availability mean that organizational change seems to have become a constant in today’s academic library. The area of collection management has not been immune from change; the increasing emphasis on electronic formats, questions about access versus ownership, and the rise of open access have all required adjustment in managing collections. Even with all this change, most academic libraries have retained an organizational structure with a single person serving as a collection management coordinator or decision maker. This presentation details the shift in one academic library from a hierarchical model with a single collection manager overseeing all selectors to a collection management team composed of three peer selectors representing the major areas of humanities, sciences, and social sciences. The team is charged with coordinating the collection and liaison activities of all selectors as well as investigating new collections initiatives, serving as a bridge between reference and technical services, developing a culture of assessment in collection development, and working with the collections budget, the Libraries’s development office, and administration. Benefits realized, challenges encountered, and “lessons learned” from this team approach will be discussed and suggestions for implementation in other libraries will be proposed

Familial colloid cyst of the third ventricle

A grant from the One-University Open Access Fund at the University of Kansas was used to defray the author's publication fees in this Open Access journal. The Open Access Fund, administered by librarians from the KU, KU Law, and KUMC libraries, is made possible by contributions from the offices of KU Provost, KU Vice Chancellor for Research & Graduate Studies, and KUMC Vice Chancellor for Research. For more information about the Open Access Fund, please see http://library.kumc.edu/authors-fund.xml.Colloid cysts of the third ventricle are rare benign lesions. They can present as incidental finding on imaging or with symptoms of obstructive hydrocephalus. To date, 18 familial cases of colloid cyst have been reported. Due to the extreme rarity of these cysts, it has been suggested that there is a genetic component involved. This report presents a familial colloid cyst in non-twin brothers who both presented in their early twenties. In addition, both of them had congenital inguinal hernia. This may represent a potential association between familial colloid cysts and congenital inguinal hernia that could provide us with insight into the genetic mechanism involved

How well does BRT perform in contrast to LRT? An Australian case study using MetroScan_TI

BRT is typically a relatively more popular transport investment in developing countries in contrast to the bias observed increasingly in developed economies towards LRT. While there have been a number of comparative assessments of BRT and LRT (in all of its possible manifestations), with a focus on one or more elements of patronage demand, and costs of construction and operation, there has, with few exceptions, been a preference for LRT which some might describe as linked to emotional ideology rather than anything to do with factual evidence on the costs, benefits and economic impact of each modal investment. In this chapter, we present a new planning tool, MetroScan as a quick-scan tool that can be used to assess the merits of BRT and LRT. MetroScan is different to other planning systems in that it accounts for the demand implications on both passenger and freight-related activity (all in the one model system), endogenous residential and employment decisions, and associated benefit-cost outcomes, as well as the wider economic impacts of transport initiatives. We use a case study setting in the Northern Beaches of Sydney to illustrate the way in which MetroScan can assess a wider suite of benefits and costs of BRT and LRT, which encompasses not only accessibility and mobility opportunities but the contribution that can be made to the productivity and value added outcomes for the local economy. This broader set of considerations is important in suggesting other ways in which a comparison of BRT and LRT might be more informative than is typically presented

Improving Transportation Project Evaluation by Recognizing the Role of Spatial Scale and Context in Measuring Non-User Economic Benefits

The usefulness of transportation project evaluation depends on the completeness of its benefit measures. Since transportation networks are intrinsically spatial, transportation improvement projects have spatial access and location characteristics that can lead to a variety of non-user economic benefits. Recent research has enabled us to better understand how spatial context and spatial heterogeneity play further roles in generating efficiency gains for non-users, in the form of productivity, income, and cost savings for both private and public sectors of the economy. This paper draws upon that body of research to expand our understanding of the means by which transportation projects can generate economic efficiency gains, and approaches needed to measure them. It covers topics beyond those captured by current definitions of “wider economic benefits,” including additional sources of scale economies associated with freight distribution and connectivity, and further public and private sector economic gains enabled by environmental and social inclusion improvement. It points to ways that non-user economic benefits can be more comprehensively defined and better measured by recognizing their spatial scale, context, and threshold effects. It also identifies ways that current benefit measurement methods introduce unintended bias into transportation investment decision-making through omission and mismeasurement. The result is a case for a refresh of thinking about how we classify and recognize non-user economic benefits in transportation evaluation, and how we apply transportation planning and economic models to support their measurement

Reward System Dysfunction as a Neural Substrate of Symptom Expression Across the General Population and Patients With Schizophrenia

Dysfunctional patterns of activation in brain reward networks have been suggested as a core element in the pathophysiology of schizophrenia. However, it remains unclear whether this dysfunction is specific to schizophrenia or can be continuously observed across persons with different levels of nonclinical and clinical symptom expression. Therefore, we sought to investigate whether the pattern of reward system dysfunction is consistent with a dimensional or categorical model of psychosis-like symptom expression. 23 patients with schizophrenia and 37 healthy control participants with varying levels of psychosis-like symptoms, separated into 3 groups of low, medium, and high symptom expression underwent event-related functional magnetic resonance imaging while performing a Cued Reinforcement Reaction Time task. We observed lower activation in the ventral striatum during the expectation of high vs no reward to be associated with higher symptom expression across all participants. No significant difference between patients with schizophrenia and healthy participants with high symptom expression was found. However, connectivity between the ventral striatum and the medial orbitofrontal cortex was specifically reduced in patients with schizophrenia. Dysfunctional local activation of the ventral striatum depends less on diagnostic category than on the degree of symptom expression, therefore showing a pattern consistent with a psychosis continuum. In contrast, aberrant connectivity in the reward system is specific to patients with schizophrenia, thereby supporting a categorical view. Thus, the results of the present study provide evidence for both continuous and discontinuous neural substrates of symptom expression across patients with schizophrenia and the general populatio

An Analysis of Private School Closings

We add to the small literature on private school supply by exploring exits of K-12 private schools. We find that the closure of private schools is not an infrequent event, and use national survey data from the National Center for Education Statistics to study closures of private schools. We assume that the probability of an exit is a function of excess supply of private schools over the demand, as well as the school's characteristics such as age, size, and religious affiliation. Our empirical results generally support the implications of the model. Working Paper 07-0

Pipes to Earth's subsurface: the role of atmospheric conditions in controlling air transport through boreholes and shafts

Understanding air exchange dynamics between underground cavities (e.g., caves, mines, boreholes, etc.) and the atmosphere is significant for the exploration of gas transport across the Earth–atmosphere interface. Here, we investigated the role of atmospheric conditions in controlling air transport inside boreholes using in situ field measurements. Three geometries were explored: (1) a narrow and deep shaft (0.1&thinsp;m wide and 27&thinsp;m deep), ending in a large underground cavity; (2) the same shaft after the pipe was lowered and separated from the cavity; and (3) a deep large-diameter borehole (59&thinsp;m deep and 3.4&thinsp;m wide). Absolute humidity was found to be a reliable proxy for distinguishing between atmospheric and cavity air masses (mainly during the winter and spring seasons) and thus to explore air transport through the three geometries. Airflow directions in the first two narrow-diameter geometries were found to be driven by changes in barometric pressure, whereas airflow in the large-diameter geometry was correlated primarily with the diurnal cycles of ambient atmospheric temperature. CO2 concentrations of  ∼ 2000&thinsp;ppm were found in all three geometries, indicating that airflow from the Earth's subsurface into the atmosphere may also be significant in the investigation of greenhouse gas emissions.</p
