Temperature and Field Dependence of Magnetic Domains in La1.2_{1.2}Sr1.8_{1.8}Mn2_2O7_7

Colossal magnetoresistance and field-induced ferromagnetism are well documented in manganite compounds. Since domain wall resistance contributes to magnetoresistance, data on the temperature and magnetic field dependence of the ferromagnetic domain structure are required for a full understanding of the magnetoresistive effect. Here we show, using cryogenic Magnetic Force Microscopy, domain structures for the layered manganite La$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$ as a function of temperature and magnetic field. Domain walls are suppressed close to the Curie temperature T$_C$, and appear either via the application of a c-axis magnetic field, or by decreasing the temperature further. At temperatures well below T$_C$, new domain walls, stable at zero field, can be formed by the application of a c-axis field. Magnetic structures are seen also at temperatures above T$_C$: these features are attributed to inclusions of additional Ruddleston-Popper manganite phases. Low-temperature domain walls are nucleated by these ferromagnetic inclusions.Comment: 6 figure

How to save the binary class variable and predicted probability of group membership from logistic regression analysis to an ASCII space-delimited data file in SPSS 17 for Windows

This note explains the steps involved and provides the SPSS syntax needed to run two-group logistic regression analysis using SPSS 17 for Windows, and output to an ASCII space-delimited data file the binary class variable and predicted probability of group membership (i.e., “Y-hat”) from an SPSS logistic regression analysis

Analyzing the Scope of Major League Baseball\u27s Antitrust Exemption in Light of San Jose v. Office of the Commissioner of Baseball

San Jose\u27s antitrust suit against Major League Baseball renews the challenge of defining the scope and applicability of the baseball antitrust exemption and the struggle to sort through the lower court precedent to arrive at a workable standard for the exemption. This Note will discuss the history of the exemption, the potential standards for applying the exemption, and analyze Judge Whyte\u27s order dismissing San Jose\u27s antitrust claims in City of San Jose v. Office of the Commissioner of Baseball to determine the persuasiveness the court\u27s opinion may have going forward as well as potential issues with the court\u27s reasoning

Session II Nursing Presentation 2: Postpartum Depression Awareness in the Neonatal Intensive Care Unit for Nurses: An Education Process

This quality improvement project is to: Implement a best practice Postpartum Depression (PPD) education and training for the Neonatal Intensive Care Unit (NICU) nurses with the goal of improving their knowledge, self-confidence and enhance recognition of symptoms of PPD in mothers of infants admitted into the NICU. This will establish a standard of care that NICU nurses could consistently use to improve the ability to identify signs and symptoms of PPD to make referrals to the unit Social Workers within the project setting and therefore provide resources to those mothers identified
