ABSTRACT
Optical emission lines are used to categorize galaxies into three groups according to their dominant central radiation source: active galactic nuclei, star formation, or low-ionization (nuclear) emission regions [LI(N)ERs] that may trace ionizing radiation from older stellar populations. Using the Wisconsin H-Alpha Mapper, we detect optical line emission in low-extinction windows within eight degrees of Galactic Center. The emission is associated with the 1.5-kiloparsec-radius "Tilted Disk" of neutral gas. We modify a model of this disk and find that the hydrogen gas observed is at least 48% ionized. The ratio [NII] λ6584 angstroms/Hα λ6563 angstroms increases from 0.3 to 2.5 with Galactocentric radius; [OIII] λ5007 angstroms and Hß λ4861 angstroms are also sometimes detected. The line ratios for most Tilted Disk sightlines are characteristic of LI(N)ER galaxies.
ABSTRACT
Unique obstacles must be overcome when providing medical care to patients who have an incomplete command of the English language. Serious barriers to effective communication may arise at the exact point where our health care system must succeed or fail. Miscommunication, differences in attitudes about health care, and various other misunderstandings interfere with or frustrate good health care for these patients and their families. Such difficulties are best overcome by the use of a professional interpreter who can ensure good communication between patients and health care professionals. My daily experiences as a professional medical interpreter and translator in Spanish provide insights into the complexities of bilingual and bicultural communication in the hospital setting. Although the examples given relate to Hispanic patients, the lessons learned can be extended to other foreign language patients as well.
