Barry Saltzman and the Theory of Climate
No full textBarry Saltzman was a giant in the fields of meteorology and climate science. A leading figure in the study of weather and climate for over 40 yr, he has frequently been referred to as the father of modern climate theory. Ahead of his time in many ways, Saltzman made significant contributions to our understanding of the general circulation and spectral energetics budget of the atmosphere, as well as climate change across a wide spectrum of time scales. In his endeavor to develop a unified theory of how the climate system works, lie played a role in the development of energy balance models, statistical dynamical models, and paleoclimate dynamical models. He was a pioneer in developing meteorologically motivated dynamical systems, including the progenitor of Lorenz\u27s famous chaos model. In applying his own dynamical-systems approach to long-term climate change, he recognized the potential for using atmospheric general circulation models in a complimentary way. In 1998, he was awarded the Carl-Gustaf Rossby medal, the highest honor of the American Meteorological Society for his life-long contributions to the study of the global circulation and the evolution of the earth\u27s climate. In this paper, the authors summarize and place into perspective some of the most significant contributions that Barry Saltzman made during his long and distinguished career. This short review also serves as an introduction to the papers in this special issue of the Journal of Climate dedicated to Barry\u27s memory
Structural stochastic stability of a simple auto-oscillatory climatic feedback system.
No full textBased on a more detailed model developed previously, governing possible feedbacks between sea ice extent (eta), deep-ocean temperature (theta), and atmospheric carbon dioxide, we have constructed a simple, deterministic, dynamical system for eta and theta that yields a stable limit cycle as a solution. To make the system more realistic we add random (white noise) forcing and explore the new response as a function of the amplitude of this stochastic forcing. -from Author
Fashion Culture: Norell: Master of American Fashion
No full textOn February 14, Jeffrey Banks, co-author of "Norell: Master of American Fashion," Ellin Saltzman, former fashion director and senior vice president at firms such as Saks Fifth Avenue, Macy’s and Bergdorf Goodman, Stan Herman, designer and former president of the CFDA, and Ralph Rucci, couturier, artist and author, came together for a sparkling introduction to Norman Norell — the first American designer to employ couture techniques, refined workmanship, and luxurious fabrics — whose dresses, coats, and suits were deemed by critics to be “the equal of Paris.” This panel discussion was moderated by Patricia Mears, deputy director of MFIT
PRESENTASI MASKULINITAS TOKOH DALAM NOVEL BEKISAR MERAH KARYA AHMAD TOHARI: ANALISIS TEORI JANET SALTZMAN CHAFETZ
No full textDiscourse of masculinity is a discussion that is widely presented in literary works. Although not expressed directly, forms of masculinity appear in line with the process of telling the behavior of existing male characters. Bekisar Merah is a novel by Ahmad Tohari which represents masculinity through various male characters. Each character has a different background, giving rise to different thoughts and actions. The concept of masculinity according to Janet Saltzman Chafetz can be seen from the male aspects in the form of (1) physical aspects; (2) functional aspects; (3) sexual aspect; (4) emotional aspects; (5) intellectual aspects; (6) interpersonal aspects. This study aims to describe the form of presentation of masculinity and its causative factors in Ahmad Tohari's Novel Bekisar Merah according to Janet Saltzman Chafetz's theory. The source of the data in this research is the document of the novel Bekisar Merah by Ahmad Tohari. The data collection technique used in this study was document analysis using the look-and-note method, in which the author first reads the contents of the novel carefully, then records any important findings. Then the validity of the data was tested by theoretical triangulation to check its suitability with Janet Saltzman Chafetz's theory of masculinity. The results of this study found that there were 47 data presenting six aspects of Janet Saltzman Chafetz's masculinity in Ahmad Tohari's novel Bekisar Merah.
 
Long period free oscillations in a three-component climate model.
No full textWe show how the prototypical models governing the unforced components of the variability can be deduced from a more general three-variable model involving an additional variable that is a measure of the underside, near-ice edge ocean temperature, and how this three-variable model can itself plausibly exhibit long term oscillations of about 100 000 years even though the time constants involved are only of the order of 10 000 years.-from Author
Centennial climate change: The unknown variability zone
No full textArguably, centennial variability has been the forgotten orphan of climate dynamics theory. In a 1990 paper titled "Three basic problems of palaeoclimate modelling", the late Barry Saltzman presented the centennial timescale as a zone with a variability gap – a demilitarized zone, separating people interested in weather from those interested in the slow evolution of climate
Velocity Spectra in the Unstable Planetary Boundary Layer
No full textModels for velocity spectra of all three components in the lower half of the unstable PBL are presented. The model spectra are written as a sum of two parts, nS(n) = A(fi, z/zi)w*2 + B(f, z/zi)u*02, a mixed layer part with a stability dependence, and a surface layer part without stability dependence and with negligible influence of z/zi in B in the surface layer; A is independent of z/zi for the horizontal components. The model agrees very well with data for variances, peak frequencies and spectra from the Kansas and Minnesota experiments. Requirements for models of spectra in the upper half of the PBL are outlined qualitatively only
Family chaos, attachment security, and responsiveness: Associations with appetite self-regulation in early childhood
No full textUntil recently, the majority of studies examining the etiology of excessive early childhood weight gain have focused on correlates or risk factors related to nutrition and physical activity (Woo Baidal et al., 2016). However, several promising areas for future research on obesity prevention have been identified, particularly in regards to child emotional and behavioral regulation (Lumeng, Taveras, Birch, & Yanovski, 2015), parent-child attachment relationships (Frankel et al., 2012), and the family context (Fiese & Bost, 2016; Woo Baidal et al., 2016). This is the first set of studies to examine how attachment and individual characteristics inform the development of appetite self-regulation, within the context of the family system.
Study 1. The first study aimed to identify whether there are domain-specific or domain-general associations between feeding and emotional responsiveness, and appetite and non-appetitive self-regulation. Few studies have assessed whether appetite self-regulation is subsumed as an undifferentiated aspect of overall self-regulation, or if it is a distinct characteristic with variation unexplained by general behavioral self-regulation. Similarly, although theoretical literature posits that feeding responsiveness is one component of responsive parenting generally, no empirical studies have examined whether it is truly differentiated from emotional responsiveness in the mealtime context. Confirmatory factor analyses were applied to observational and self-report data collected from a subsample of families (n = 110) of 18-24 month old children in the larger STRONG Kids 2 (SK2) Birth Cohort Project (N = 451). Findings indicate that responsiveness is a domain-specific construct, but that appetite self-regulation may be one dimension of a higher-order domain-general construct of overall self-regulation. Appetite self-regulation was distinct, but highly related to children’s non-food related executive functioning. Feeding responsiveness was distinct from emotional responsiveness, and self-reported emotional responsiveness was distinct from emotional responsiveness observed during mealtimes. These findings highlight the importance of specificity in context and measurement.
Study 2. The second study aimed to examine associations between maternal attachment, family factors (household chaos, distractions, family mealtime routines), and maternal responsiveness. Structural equation modeling techniques were applied to observational and self-report data collected from the subsample of families in the SK2 project (n = 110), to assess direct, indirect, and interactive effects of family and attachment factors on responsiveness. More household chaos was associated with less feeding and self-reported emotional responsiveness. More maternal mealtime distractions were associated with less observed emotional responsiveness. Regarding interactive effects, mothers who were more distracted at mealtimes and highly insecure engaged in less observed emotional responsiveness. However, more household chaos was associated with less self-reported emotional responsiveness only among very secure mothers; very high levels of attachment insecurity attenuated these effects.
Study 3. The third study aimed to examine direct, indirect, and interactive associations between family factors, attachment, and appetite self-regulation in early childhood. Path analyses were applied to observational and self-report data collected from the subsample of families in the SK2 project (n = 110), to assess direct, indirect, and interactive effects of family factors, attachment, and responsiveness on child appetite self-regulation. Family factors (high chaos, few routines) were directly—but not indirectly via responsiveness—associated with child appetite dysregulation. Routines were associated with child appetite dysregulation among children of mothers who were highly insecure. Chaos was associated with appetite dysregulation among children of mothers who reported less emotional responsiveness.
Family and attachment factors play an important role in promoting parent responsiveness and child appetite dysregulation. These studies provide a window into the ways that these processes may influence child health. Together, findings point to a need to consider the multifaceted nature of risk and resilience, and specificity in measurement and conceptualization for future studies. This study contributes nuance to the literature on self-regulation and responsiveness, and specificity to our understanding of how individual differences in appetite self-regulation develop in early childhood. The long-term aim of this program of research is to develop recommendations for interventions designed to prevent childhood obesity.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-05-01The student, Jaclyn Saltzman, accepted the attached license on 2018-04-12 at 15:04.The student, Jaclyn Saltzman, submitted this Dissertation for approval on 2018-04-12 at 15:08.This Dissertation was approved for publication on 2018-04-12 at 15:20.DSpace SAF Submission Ingestion Package generated from Vireo submission #12215 on 2018-08-31 at 17:18:34Made available in DSpace on 2018-09-04T20:34:03Z (GMT).
