Characterization and analysis of azimuthally sensitive correlations
A unified framework for describing the azimuthal dependence of two-particle
correlations in heavy-ion collisions is introduced, together with the methods
for measuring the corresponding observables. The generalization to azimuthal
correlations between more than two particles is presented.Comment: 7 pages; talk given at Hot Quarks 2004, Taos (NM), July 18-24,200
Probing spin fractionalization with ESR-STM absolute magnetometry
The emergence of effective spins at the edges of Haldane spin
chains is one of the simplest examples of fractionalization. Whereas there is
indirect evidence of this phenomenon, direct measurement of the magnetic moment
of an individual edge spin remains to be done. Here we show how scanning tunnel
microscopy electron-spin resonance (ESR-STM) can be used to map the stray field
created by the fractional edge spin and we propose efficient methods to
invert the Biot-Savart equation, obtaining the edge magnetization map. This
permits one to determine unambiguously the two outstanding emergent properties
of fractional degrees of freedom, namely, their fractional magnetic moment and
their localization length
Predictors of discordance among Chilean families
Parent-youth agreement on parental behaviors can characterize effective parenting. Although
discordance in families may be developmentally salient and harmful to youth outcomes, predictors
of discordance have been understudied, and existing research in this field has been mostly limited
to North American samples. This paper addressed this literature gap by using data from a
community-based study of Chilean adolescents. Analysis was based on 1,068 adolescents in
Santiago, Chile. The dependent variable was discordance which was measured by the difference
between parent and youth’s assessment of parental monitoring. Major independent variables for
this study were selected based on previous research findings that underscore youth’s
developmental factors, positive parental and familial factors and demographic factors. Descriptive
and multivariate analyses were conducted to examine the prevalence and associations between
youth, parental and familial measures with parent-youth discordance. There was a sizable level of
discordance between parent and youth’s report of parental monitoring. Youth’s gender and
externalizing behavior were significant predictors of discordance. Warm parenting and family
involvement were met with decreases in discordance. The negative interaction coefficients
between parental warmth and youth’s gender indicated that positive parental and familial
measures have a greater effect on reducing parent-youth discordance among male youths. Results
support the significance of positive family interactions in healthy family dynamics. Findings from
this study inform the importance of services and interventions for families that aim to reduce
youth’s problem behavior and to create a warm and interactive family environment.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4181713/Accepted manuscrip
Can AI Become an Information Literacy Ally? A Survey of Library Instructor Perspectives on ChatGPT
Libraries can play a role in navigating the AI era by integrating these tools into information literacy (IL) programs. To implement generative AI tools like ChatGPT effectively, it is important to understand the attitudes of library professionals involved in IL instruction toward this tool and their intention to use it for instruction. This study explored perceptions of ChatGPT using survey data that included acceptance factors and potential uses derived from the emerging literature. While some librarians saw potential, others found it too unreliable to be useful; yet the vast majority imagined utilizing the tool in the future
ChatGPT is a Liar and other Lessons Learned from Information Literacy Instructors
Wondering where generative artificial intelligence (AI) fits in information literacy instruction? This session will share findings from a recent survey of library professionals on how they are already teaching about and using AI powered ChatGPT in information literacy instruction and where they see potential opportunities and areas of concern. Survey analysis will include information about attitudes, current and anticipated use, and descriptions of teaching methods that leverage the technology. As we navigate the survey results, attendees will have the opportunity to share their own perspectives on the same questions via live polling. We will then turn to attendees to share their experiences and the challenges they have found in addressing the needs of their library communities as they explore applications of AI in their research, instruction, writing, and creative endeavors. As we explore the topic we will cover issues ranging from what generative AI is and is not, “hallucinated” information, deep fakes, misinformation, biased training data, documenting use of AI, privacy, copyright and costs
