The ACIGA Data Analysis programme

The Data Analysis programme of the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA) was set up in 1998 by the first author to complement the then existing ACIGA programmes working on suspension systems, lasers and optics, and detector configurations. The ACIGA Data Analysis programme continues to contribute significantly in the field; we present an overview of our activities.Comment: 10 pages, 0 figures, accepted, Classical and Quantum Gravity, (Proceedings of the 5th Edoardo Amaldi Conference on Gravitational Waves, Tirrenia, Pisa, Italy, 6-11 July 2003

Optical and infrared spectrophotometry of 18 Markarian galaxies

Slit spectra, spectrophotometric scans and infrared broad band observations are presented. Eight of the program galaxies can be classified as Seyfert galaxies. Arguments are given that thermal, nonthermal and stellar radiation components were present. One group of Seyfert galaxies was characterized both by the presence of a high density region of gas and by a continuum dominated by nonthermal radiation. The continua of the remaining program Seyferts, which did not have a high density region of gas, were dominated by thermal radiation from dust and a stellar continuum. Ten of the galaxies, which are not Seyfert galaxies, are shown to be examples of extragalactic H 2 regions

Natural Caregiving Practices and Mothers\u27 Decisions

Mothers care for their infants in various ways, many similar and others more unique, and are influenced by a variety of factors. Influences such as doctors\u27 advice, attending prenatal and child development classes, reading books and magazines, and learning from personal experience contribute to the caregiving decisions mothers make. A type of parenting that focuses on the responsiveness and sensitivity of the mother to the infant\u27s needs is known as natural parenting. Natural parenting involves caregiving practices that are expected to co-occur, such as breastfeeding and frequently maintaining close physical contact with the infant. Two other practices that some mothers find intuitive and natural are co-sleeping and singing. Singing, in particular, may or may not be related to natural parenting, but has been found to be culturally universal and offers benefits to the infant\u27s health and development. In this study mothers of 2- to 6-month-old infants were asked about specific caregiving practices, such as feeding, sleeping, carrying, and singing. Mothers\u27 responses were analyzed using quantitative and qualitative methods. The quantitative responses show how one kind of caregiving decision, such as feeding method, is related to other caregiving decisions, such as where the baby sleeps or whether to sing to the infant. The qualitative ratings delve further into the sources of information and decisions mothers make in their caregiving practices. Practitioners and health agencies may benefit in promoting practices that are beneficial to mothers and infants by knowing how caregiving practices and decisions are related

thesisThe primary purpose of this study was to systematically examine the behaviors of a successful female and male high school coach of girls' basketball teams and compare to collegiate coach Pat Summitt. A secondary purpose of the study was to examine the correlation between coaches' behaviors and athlete expectancy status. Throughout the season both coaches' verbal and nonverbal behaviors were video recorded over the course of eight practices. A total of 553 minutes consisting of 3,141 of a female coach's practice behaviors and a total of 590 minutes consisting of 3,678 of the male coach's practice behaviors were coded using the Arizona State University of Observation Instrument. Both the female coach and male coach provided instruction more often (female 35.5%, n = 1114, male 29.2%, n = 1072) then any coaching behavior when the categories of preinstruction, concurrent instruction, and postinstruction were combined. Results indicated that the female coach exhibited management (27.9%) more than any other behavior category. The highest category for the male coach was praise (22.1%). The praise to scold ratio for male and female coaches exceeded a 2:1 ratio with male coach exhibiting more praise behaviors and the female coach exhibited less scold behaviors than the male. A Pearson Product Correlation suggested that both coaches' perceptions of athletes' expectancy remained consistent from the beginning to the end of the season. Contrary to predictions, a MANOVA revealed no differences in the quantity or quality of the coaching behaviors that both the female and male coach directed toward high and low expectancy players in the given categories. The implications from this data suggest that successful coaches treated athletes the same in terms of the 13 coaching behaviors and that coaches spend the majority of their time using instruction

A comparison of efficient permutation tests for unbalanced ANOVA in two by two designs--and their behavior under heteroscedasticity

We compare different permutation tests and some parametric counterparts that are applicable to unbalanced designs in two by two designs. First the different approaches are shortly summarized. Then we investigate the behavior of the tests in a simulation study. A special focus is on the behavior of the tests under heteroscedastic variances.Comment: 20 pages, 9 figures, Working Paper of the Department of Management And Enigineering of the University of Padov

Real Time Relativity: exploration learning of special relativity

Real Time Relativity is a computer program that lets students fly at relativistic speeds though a simulated world populated with planets, clocks, and buildings. The counterintuitive and spectacular optical effects of relativity are prominent, while systematic exploration of the simulation allows the user to discover relativistic effects such as length contraction and the relativity of simultaneity. We report on the physics and technology underpinning the simulation, and our experience using it for teaching special relativity to first year university students
