Aaarrrggg I’m a Pirate: Cloud-Streaming Services and Their Effects on Music Consumption and Music Piracy

With advances in technology, music consumption among listeners has vastly changed throughout the years. These changes in technology have allowed piracy to thrive and prosper while physical sales vastly decreased. Previous studies have explored how music piracy effects music consumption. This study goes beyond the work that previous studies have explored by examining a new form of music consumption—cloud-streaming websites. This thesis examines how cloud-streaming services have affected music consumption and music piracy through an analysis of an online study distributed to music consumers. The results showed that cloud-streaming services do change the way that people consume music. Respondents demonstrated a decline in piracy after their use of cloud-streaming services as well as a slight decline in amount of music purchased. Furthermore, respondents believed that cloud-streaming services would reinforce consumer’s acceptance of music piracy, although their own actions indicated the opposite

A ROTTERDAM APPLICATION TO INTERNATIONAL TRADE IN FRESH APPLES: A DIFFERENTIAL APPROACH

A Rotterdam import allocation model is used to fit import data for fresh apples in four importing markets important to U.S. apple exporters. Nested tests rejected homotheticity but could not reject homogeneity, symmetry, or separability among import suppliers. A Monte Carlo test rejected first-order autocorrelation in each market. Expenditure and price elasticities are calculated and reported.International Relations/Trade,

Dust composition and mass-loss return from the luminous blue variable R71 in the LMC

We present an analysis of mid-and far-infrared (IR) spectrum and spectral energy distribution (SED) of the LBV R71 in the LMC.This work aims to understand the overall contribution of high-mass LBVs to the total dust-mass budget of the interstellar medium (ISM) of the LMC and compare this with the contribution from low-mass asymptotic giant branch (AGB) stars. As a case study, we analyze the SED of R71. We compiled all the available photometric and spectroscopic observational fluxes from various telescopes for a wide wavelength range (0.36 -- 250\,$\mu$m). We determined the dust composition from the spectroscopic data, and derived the ejected dust mass, dust mass-loss rate, and other dust shell properties by modeling the SED of R71. We noted nine spectral features in the dust shell of R71 by analyzing Spitzer spectroscopic data. Among these, we identified three new crystalline silicate features. We computed our model spectrum by using 3D radiative transfer code MCMax. Our model calculation shows that dust is dominated by amorphous silicates, with some crystalline silicates, metallic iron, and a very tiny amount of polycyclic aromatic hydrocarbon (PAH) molecules. The presence of both silicates and PAHs indicates that the dust has a mixed chemistry. We derived a dust mass of 0.01 M$_\odot$, from which we arrive at a total ejected mass of $\approx$ 5 M$_\odot$. This implies a time-averaged dust mass-loss rate of 2.5$\times$10$^{-6}$ M$_\odot$\,yr$^{-1}$ with an explosion about 4000 years ago. We assume that the other five confirmed dusty LBVs in the LMC loose mass at a similar rate, and estimate the total contribution to the mass budget of the LMC to be $\approx$ 10$^{-5}$ M$_\odot$\,yr$^{-1}$, which is comparable to the contribution by all the AGB stars in the LMC. Based on our analysis on R71, we speculate that LBVs as a class may be an important dust source in the ISM of the LMC.Comment: 10 pages, 6 figures, 2 table

Knowledge sharing for the development of service learning champions

Published ArticleChampions engage in knowledge sharing within triad service learning partnerships. However, the role of knowledge sharing in the development of champions needs further exploration. This qualitative study within a constructivist paradigm, shares the effect of mutual learning at the University of the Free State in the nursing education field. Selected international, national, regional and local champions shared perceptions through semi-structured interviews, indicating that: (1) champions could be situated in any sector of the triad model; (2) sharing different kinds of knowledge develop different domains; and (3) connection, collaboration and continuous communication should guide knowledge sharing towards societal change and reciprocal empowerment

Make me think! Exploring library UX through the lens of (critical) information literacy

While (critical) information literacy (IL) acknowledges the political, economic, and social forces that shape complex information environments, library user experience (UX) typically centers efficiency and ‘seamlessness,’ ignoring the power structures and values that condition learning. In this paper, we explore the tensions between IL and UX values and practices, with the aim of starting a conversation about how these two related fields can become more closely aligned

\u3cem\u3eVeratrum parviflorum\u3c/em\u3e: An Underexplored Source for Bioactive Steroidal Alkaloids

Plants of the Veratrum genus have been used throughout history for their emetic properties, rheumatism, and for the treatment of high blood pressure. However, inadvertent consumption of these plants, which resemble wild ramps, induces life-threatening side effects attributable to an abundance of steroidal alkaloids. Several of the steroidal alkaloids from Veratrum spp. have been investigated for their ability to antagonize the Hedgehog (Hh) signaling pathway, a key pathway for embryonic development and cell proliferation. Uncontrolled activation of this pathway is linked to the development of various cancers; most notably, basal cell carcinoma and acute myeloid leukemia. Additional investigation of Veratrum spp. may lead to the identification of novel alkaloids with the potential to serve as chemotherapeutics. V. parviflorum is a relatively uncommon species of Veratrum that resides in the southeastern regions of North America. The phytochemical profile of this plant remains largely unexplored; however, bioactive steroidal alkaloids, including cyclopamine, veratramine, veratridine, and verazine were identified in its extract. The structural elucidation and bioactivity assessment of steroidal alkaloids in lesser abundance within the extract of V. parviflorum may yield potent Hh pathway inhibitors. This review seeks to consolidate the botanical and phytochemical information regarding V. parviflorum

Cane Ridge in Context: Perspectives on Barton W. Stone and the Revival

The year 1991 was the 200th anniversary year of the construction of the Cane Ridge Meetinghouse by a Presbyterian congregation in frontier Kentucky. To celebrate this event, the Disciples of Christ Historical Society hosted a number of special events, including lectures and addresses on the legacy of Barton W. Stone as well as on the background and meaning of the revival. This volume brings together several of these addresses and the chapters are arranged to proceed from reflections upon the various ways Barton W. Stone has been remembered in the Stone-Campbell traditions. Contributors include Anthony L. Dunnavant, Richard L. Harrison Jr, Paul Blowers, C. Leonard Allen, D. Newell Williams, Ronald P. Byars, Newton B. Fowler, Samuel S. Hill, and Howard E. Short.https://digitalcommons.acu.edu/acu_library_books/1012/thumbnail.jp

This study investigates whether Dutch newspaper articles use the term ‘euthanasia’ according to the legal definition and determines what arguments for and against euthanasia they contain. Methods: We did an electronic search of seven Dutch national newspapers between January 2009 and May 2010 and conducted a content analysis. Results: Of the 284 articles containing the term ‘euthanasia’, 24% referred to practices outside the scope of the law, mostly relating to the forgoing of life-prolonging treatments and assistance in suicide by others than physicians. Of the articles with euthanasia as the main topic, 36% described euthanasia in the context of a terminally ill patient, 24% for older persons, 16% for persons with dementia, and 9% for persons with a psychiatric disorder. The most frequent arguments for euthanasia included the importance of self-determination and the fact that euthanasia contributes to a good death. The most frequent arguments opposing euthanasia were that suffering should instead be alleviated by better care, that providing euthanasia can be disturbing, and that society should protect the vulnerable. Conclusions: Of the newspaper articles, 24% uses the term ‘euthanasia’ for practices that are outside the scope of the euthanasia law. Typically, the more unusual cases are discussed. This might lead to misunderstandings between citizens and physicians. Despite the Dutch legalisation of euthanasia, the debate about its acceptability and boundaries is ongoing and both sides of the debate are clearly represented
