Purdue Libraries Publishing Services: The Domino Effect of Repository-Based Publishing, Outreach, and Promotion

Technical reports have always posed problems for libraries and librarians. They are often bibliographically inconsistent, difficult to source, and published to varying standards of quality. In some fields, these reports are also large in number and central in importance. In many cases, technical reports are just one of many collections that are tied to a particular research center or group. These research centers or groups may also produce data papers, hosted conference proceedings, and other report series, which may also suffer from many of the same issues facing technical reports. In several situations these research centers and groups are unaware of the publishing solutions offered by their own libraries and librarians, in many cases from a minimal to no additional costs. This breakout session will discuss a case study of how the Purdue Libraries Publishing Services division has found innovative ways to face the problems of the Joint Transportation Research Program’s technical reports and their other affiliated collections. This session will also discuss how these innovative solutions for technical reports created a domino effect for future promotion and outreach of the repository by the participating research centers and groups by the deposit of additional content and the hosting repository designation for the Purdue e-Pubs repository for the Purdue Road School Annual Conference. Audience members can expect to hear about the challenges of repository-based publishing of technical reports in the digital age, and the opportunities that exist for improving discoverability and dissemination in the networked environment through promotion and outreach

Organizational Satisfaction And Participation: Findings from a Study Of ACE Members

Organizations which serve information professionals, such as Agricultural Communicators in Education, must continue to respond to the needs of members through relevant programs and professional opportunities. The study reported here examines satisfaction and participation within the organization. Overall, the study found broad-based member satisfaction. But while there is widespread support, there are segments of the membership which need attention. Findings also identify organizational areas which can be improved, particularly in the conduct of the Critique and Awards Program and in meeting the expectations of members involved in Special Interest Groups (SIG). Specific questions that may have organizational policy implications are raised. The study\u27s finding that member participation positively is related to overall satisfaction with ACE is encouraging. One important goal for ACE, then, would be to encourage increased participation. And, because newer members tend to be the most dissatisfied with ACE, emphasis should be placed on immediately getting them more involved in ACE activities

Evidence for a diffusion-controlled mechanism for fluorescence blinking of colloidal quantum dots

Fluorescence blinking in nanocrystal quantum dots is known to exhibit power-law dynamics, and several different mechanisms have been proposed to explain this behavior. We have extended the measurement of quantum-dot blinking by characterizing fluctuations in the fluorescence of single dots over time scales from microseconds to seconds. The power spectral density of these fluctuations indicates a change in the power-law statistics that occurs at a time scale of several milliseconds, providing an important constraint on possible mechanisms for the blinking. In particular, the observations are consistent with the predictions of models wherein blinking is controlled by diffusion of the energies of electron or hole trap states

Prostituição, ofensas e bofetadas nos periódicos de Florianópolis entre 1900 – 1930

This article have by aim to tell a part of the history of quotidian of violences and attacks on women who provide sexual services in Florianópolis between the years 1900-1930, found in the newspaper of the period.Esse artigo busca contar uma parte da história do cotidiano de violências e agressões sofridas por mulheres que prestavam serviços sexuais em Florianópolis entre os anos de 1900-1930, presente nos jornais do período

Corda branca em carne negra: Os escravos e a pena de morte por enforcamento no Brasil Império

Este artigo busca analisar uma pequena parte da história da pena de morte imposta aos escravos no Brasil Império, e, tenta compreender um pouco do contexto brasileiro da época, e das dificuldades de controle sobre a cada vez maior população escrava. Também se pretende entender o mecanismo legal, a Lei de 10 de junho de 1835, criado para facilitar e acelerar os processos jurídicos em vista da necessidade da punição contra escravos rebeldes, insurgentes, revoltosos e homicidas de senhores e seus protegidos. Algumas especificidades serão tratadas nesse trabalho, que objetiva entender algumas histórias e personagens que exemplificarão o modus operandi de todo o processo de execução imposta aos escravos: o cortejo rumo ao patíbulo, o carrasco responsável pela peculiar maneira de enforcar empregada no Brasil Império, e casos que auxiliam na exemplificação das dificuldades de interpretação das leis, causando situações contraditórias e arbitrárias muitas vezes

Exploring the effects of personality traits on the perception of emotions from prosody

It has repeatedly been argued that individual differences in personality influence emotion processing, but findings from both the facial and vocal emotion recognition literature are contradictive, suggesting a lack of reliability across studies. To explore this relationship further in a more systematic manner using the Big Five Inventory, we designed two studies employing different research paradigms. Study 1 explored the relationship between personality traits and vocal emotion recognition accuracy while Study 2 examined how personality traits relate to vocal emotion recognition speed. The combined results did not indicate a pairwise linear relationship between self-reported individual differences in personality and vocal emotion processing, suggesting that the continuously proposed influence of personality characteristics on vocal emotion processing might have been overemphasized previously

The good, the bad and the implicit: a comprehensive approach to annotating explicit and implicit sentiment

We present a fine-grained scheme for the annotation of polar sentiment in text, that accounts for explicit sentiment (so-called private states), as well as implicit expressions of sentiment (polar facts). Polar expressions are annotated below sentence level and classified according to their subjectivity status. Additionally, they are linked to one or more targets with a specific polar orientation and intensity. Other components of the annotation scheme include source attribution and the identification and classification of expressions that modify polarity. In previous research, little attention has been given to implicit sentiment, which represents a substantial amount of the polar expressions encountered in our data. An English and Dutch corpus of financial newswire, consisting of over 45,000 words each, was annotated using our scheme. A subset of this corpus was used to conduct an inter-annotator agreement study, which demonstrated that the proposed scheme can be used to reliably annotate explicit and implicit sentiment in real-world textual data, making the created corpora a useful resource for sentiment analysis

Development and evaluation of a quality score for abstracts

BACKGROUND: The evaluation of abstracts for scientific meetings has been shown to suffer from poor inter observer reliability. A measure was developed to assess the formal quality of abstract submissions in a standardized way. METHODS: Item selection was based on scoring systems for full reports, taking into account published guidelines for structured abstracts. Interrater agreement was examined using a random sample of submissions to the American Gastroenterological Association, stratified for research type (n = 100, 1992–1995). For construct validity, the association of formal quality with acceptance for presentation was examined. A questionnaire to expert reviewers evaluated sensibility items, such as ease of use and comprehensiveness. RESULTS: The index comprised 19 items. The summary quality scores showed good interrater agreement (intra class coefficient 0.60 – 0.81). Good abstract quality was associated with abstract acceptance for presentation at the meeting. The instrument was found to be acceptable by expert reviewers. CONCLUSION: A quality index was developed for the evaluation of scientific meeting abstracts which was shown to be reliable, valid and useful

Revisiting Scalar and Pseudoscalar Couplings with Nucleons

Certain dark matter interactions with nuclei are mediated possibly by a scalar or pseudoscalar Higgs boson. The estimation of the corresponding cross sections requires a correct evaluation of the couplings between the scalar or pseudoscalar Higgs boson and the nucleons. Progress has been made in two aspects relevant to this study in the past few years. First, recent lattice calculations show that the strange-quark sigma term $\sigma_s$ and the strange-quark content in the nucleon are much smaller than what are expected previously. Second, lattice and model analyses imply sizable SU(3) breaking effects in the determination on the axial-vector coupling constant $g_A^8$ that in turn affect the extraction of the isosinglet coupling $g_A^0$ and the strange quark spin component $\Delta s$ from polarized deep inelastic scattering experiments. Based on these new developments, we re-evaluate the relevant nucleon matrix elements and compute the scalar and pseudoscalar couplings of the proton and neutron. We also find that the strange quark contribution in both types of couplings is smaller than previously thought.Comment: 17 pages, Sec. II is revised and the pion-nucleon sigma term extracted from the scattering data is discussed. Version to appear in JHE
