We have recently commissioned a novel infrared (0:9-1:7 μm) integral field spectrograph (IFS) called the Wide Integral Field Infrared Spectrograph (WIFIS). WIFIS is a unique instrument that offers a very large field-of-view (5000 x 2000) on the 2.3-meter Bok telescope at Kitt Peak, USA for seeing-limited observations at moderate spectral resolving power. The measured spatial sampling scale is ~ 1 x 1" and its spectral resolving power is R ~ 2; 500 and 3; 000 in the z J (0:9 - 1:35 μm) and Hshort (1:5 - 1:7 μm) modes, respectively. WIFIS's corresponding etendue is larger than existing near-infrared (NIR) IFSes, which are mostly designed to work with adaptive optics systems and therefore have very narrow fields. For this reason, this instrument is specifically suited for studying very extended objects in the near-infrared such as supernovae remnants, galactic star forming regions, and nearby galaxies, which are not easily accessible by other NIR IFSes. This enables scientific programs that were not originally possible, such as detailed surveys of a large number of nearby galaxies or a full accounting of nucleosynthetic yields of Milky Way supernova remnants. WIFIS is also designed to be easily adaptable to be used with larger telescopes. In this paper, we report on the overall performance characteristics of the instrument, which were measured during our commissioning runs in the second half of 2017. We present measurements of spectral resolving power, image quality, instrumental background, and overall efficiency and sensitivity of WIFIS and compare them with our design expectations. Finally, we present a few example observations that demonstrate WIFIS's full capability to carry out infrared imaging spectroscopy of extended objects, which is enabled by our custom data reduction pipeline.

Purpose: This article reports the results of a randomized,controlledevaluationofPartnersinCaregivingin a Special Care Environment, an intervention designed to improve communication and cooperation between staffandfamiliesofresidentsinnursinghomedementia programs. Design and Methods: Participants included 388 family members and 384 nursing staff members recruited from 20 nursing homes, randomly assigned to treatment and control conditions. Project staff conducted training sessions on communication and conflict-resolution techniques with two groups at the intervention sites: staff and residents’ family members, followed by a joint meeting with facility administrators. Results: Families, staff, residents, and facility programs in the intervention facilities all demonstrated positive outcomes from program participation. Families experienced significant improvement in communicating with staff and in staff behaviors toward them, and spouses of residents increased their care involvement. Staff reported reduced conflict with families and reduced depression; burnout for nurses increased for individuals in the control group but not those in the treatment group. Behavioral symptoms decreased for residents, and facilities implemented more family-focused programs. Implications: Effective staff and family partnerships are critical in caring forresidentswithdementia.ThePartnersinCaregiving inaSpecialCareEnvironmentprogramisanevidencebased intervention that enables these partnerships to develop and thrive, translating into improved experiences for residents, families, and staff.

The current study examined whether the Nurse Family Partnership (NFP), an intervention in which mothers received home visitation by registered nurses pre- and postnatally, reduced mothers' vulnerability to the effects of stressful life events several years after the program was completed. Data from a randomized trial of the NFP were examined for mothers (N = 324) who were generally low-income, young, and unmarried at the time of the birth of their first child. Structured interviews were done with mothers about 15 years after the program began. Results showed that experiencing uncontrollable stressful life events, such as the death of a loved one, led to fewer negative outcomes (fewer mental health problems, less binge drinking, and better parenting practices) among nurse-visited mothers than among mothers receiving no visitation. Furthermore, the program's effect on reducing vulnerability to the negative impact of life events was particularly evident among parents who were younger or had a lower sense of personal control at intake. These findings suggest that, in addition to preventing the occurrence of negative outcomes that were direct targets of the intervention, the NFP more generally enhanced mothers' ability to cope with future stressful life events.

This study investigated the relationship between child maltreatment and the early onset of problem behaviors in the Elmira Nurse Home Visitation Program. Participants were predominantly low-income and unmarried mothers and their first-born children who were randomized either to receive over 2 years of home-visitation services by nurses or to be placed in a comparison group. Data were drawn from a follow-up study that took place when the children were 15 years of age. Results demonstrated that, in the comparison group, child maltreatment was associated with significant increases in the number of early onset problem behaviors reported by the youth. For the youth in the nurse-visited group there was no relationship between maltreatment and early onset problem behaviors. We suggest that this finding was due to the effects of the intervention in reducing the number as well as the developmental timing of the maltreatment incidents. Results suggest that prenatal and infancy home visiting by nurses can moderate the risk of child maltreatment as a predictor of conduct problems and antisocial behavior among children and youth born into at-risk families.

We discuss properties of the atmospheric water vapor above the high Andean plateau region known as the Llano de Chajnantor, in the Atacama Desert of northern Chile. A combination of radiometric and radiosonde measurements indicate that the median column of precipitable water vapor (PWV) above the plateau at an elevation of 5000 m is approximately 1.2 mm. The exponential scaleheight of the water vapor density in the median Chajnantor atmosphere is 1.13 km; the median PWV is 0.5 mm above an elevation of 5750 m. Both of these numbers appear to be lower at night. Annual, diurnal and other dependences of PWV and its scaleheight are discussed, as well as the occurrence of temperature inversion layers below the elevation of peaks surrounding the plateau. We estimate the background for infrared observations and sensitivities for broad band and high resolution spectroscopy. The results suggest that exceptional atmospheric conditions are present in the region, yielding high infrared transparency and high sensitivity for future ground-based infrared telescopes., 25 pages, 11 figures, to appear in the PASP (July 2001)

Two randomized trials of prenatal and infancy home visitation conducted in semirural and urban areas are described and their results presented. The studies provide consistent findings that nurse home visitors can improve women's health related behaviors, qualities of infant caregiving, and can help women improve their own life-course development (reflected in behaviors such as rates of subsequent pregnancies and births, and receipt of welfare). The effects of the program on reducing the rates of dysfunctional care (reflected in rates of child maltreatment and health care encounters for injuries) were concentrated in women with few psychological resources. Reviews of other randomized trials indicate that to produce comparable effects, interventions must include those program ingredients embodied in the model tested in these two trials. © 1998 John Wiley & Sons, Inc.

The TEDI (TripleSpec - Exoplanet Discovery Instrument) will be the first instrument fielded specifically for finding low-mass stellar companions. The instrument is a near infra-red interferometric spectrometer used as a radial velocimeter. TEDI joins Externally Dispersed Interferometery (EDI) with an efficient, medium-resolution, near IR (0.9 - 2.4 micron) echelle spectrometer, TripleSpec, at the Palomar 200" telescope. We describe the instrument and its radial velocimetry demonstration program to observe cool stars., 6 Pages, To Appear in SPIE Volume 6693, Techniques and Instrumentation for Detection of Exoplanets III

Purpose: This article reports on a randomized, controlled study of Partners in Caregiving, an intervention designed to increase cooperation and effective communication between family members and nursing home staff. Design and Methods: Participants included 932 relatives and 655 staff members recruited from 20 nursing homes, randomly assigned to treatment and control conditions. Parallel training sessions on communication and conflict resolution techniques were conducted with the family and staff in the treatment group, followed by a joint meeting with facility administrators. Results: Positive outcomes were found for both family and staff members in the treatment group. Both groups showed improved attitudes toward each other, families of residents with dementia reported less conflict with staff, and staff reported a lower likelihood of quitting. Implications: Multiple studies report significant interpersonal stress between family members of nursing home residents and facility staff members. Partners in Caregiving appears to be an effective way to improve family‐ staff relationships in nursing homes.

background Despite dramatic declines in children’s blood lead concentrations and a lowering of the Centers for Disease Control and Prevention’s level of concern to 10 µg per deciliter (0.483 µmol per liter), little is known about children’s neurobehavioral functioning at lead concentrations below this level. methods We measured blood lead concentrations in 172 children at 6, 12, 18, 24, 36, 48, and 60 months of age and administered the Stanford–Binet Intelligence Scale at the ages of 3 and 5 years. The relation between IQ and blood lead concentration was estimated with the use of linear and nonlinear mixed models, with adjustment for maternal IQ, quality of the home environment, and other potential confounders. results The blood lead concentration was inversely and significantly associated with IQ. In the linear model, each increase of 10 µg per deciliter in the lifetime average blood lead concentration was associated with a 4.6-point decrease in IQ (P=0.004), whereas for the subsample of 101 children whose maximal lead concentrations remained below 10 µg per deciliter, the change in IQ associated with a given change in lead concentration was greater. When estimated in a nonlinear model with the full sample, IQ declined by 7.4 points as lifetime average blood lead concentrations increased from 1 to 10 µg per deciliter. conclusions Blood lead concentrations, even those below 10 µg per deciliter, are inversely associated with children’s IQ scores at three and five years of age, and associated declines in IQ are greater at these concentrations than at higher concentrations. These findings suggest that more U.S. children may be adversely affected by environmental lead than previously estimated.

Objective. To examine the effectiveness of home visiting by paraprofessionals and by nurses as separate means of improving maternal and child health when both types of visitors are trained in a program model that has demonstrated effectiveness when delivered by nurses.Methods. A randomized, controlled trial was conducted in public- and private-care settings in Denver, Colorado. One thousand one hundred seventy-eight consecutive pregnant women with no previous live births who were eligible for Medicaid or who had no private health insurance were invited to participate. Seven hundred thirty-five women were randomized to control, paraprofessional, or nurse conditions.Nurses completed an average of 6.5 home visits during pregnancy and 21 visits from birth to the children’s second birthdays. Paraprofessionals completed an average of 6.3 home visits during pregnancy and 16 visits from birth to the children’s second birthdays.The main outcomes consisted of changes in women’s urine cotinine over the course of pregnancy; women’s use of ancillary services during pregnancy; subsequent pregnancies and births, educational achievement, workforce participation, and use of welfare; mother-infant responsive interaction; families’ home environments; infants’ emotional vulnerability in response to fear stimuli and low emotional vitality in response to joy and anger stimuli; and children’s language and mental development, temperament, and behavioral problems.Results. Paraprofessional-visited mother-child pairs in which the mother had low psychological resources interacted with one another more responsively than their control-group counterparts (99.45 vs 97.54 standard score points). There were no other statistically significant paraprofessional effects.In contrast to their control-group counterparts, nurse-visited smokers had greater reductions in cotinine levels from intake to the end of pregnancy (259.0 vs 12.32 ng/mL); by the study child’s second birthday, women visited by nurses had fewer subsequent pregnancies (29% vs 41%) and births (12% vs 19%); they delayed subsequent pregnancies for longer intervals; and during the second year after the birth of their first child, they worked more than women in the control group (6.83 vs 5.65 months).Nurse-visited mother-child pairs interacted with one another more responsively than those in the control group (100.31 vs 98.99 standard score points). At 6 months of age, nurse-visited infants, in contrast to their control-group counterparts, were less likely to exhibit emotional vulnerability in response to fear stimuli (16% vs 25%) and nurse-visited infants born to women with low psychological resources were less likely to exhibit low emotional vitality in response to joy and anger stimuli (24% vs 40% and 13% vs 33%). At 21 months, nurse-visited children born to women with low psychological resources were less likely to exhibit language delays (7% vs 18%); and at 24 months, they exhibited superior mental development (90.18 vs 86.20 Mental Development Index scores) than their control-group counterparts. There were no statistically significant program effects for the nurses on women’s use of ancillary prenatal services, educational achievement, use of welfare, or their children’s temperament or behavior problems.For most outcomes on which either visitor produced significant effects, the paraprofessionals typically had effects that were about half the size of those produced by nurses.Conclusions. When trained in a model program of prenatal and infancy home visiting, paraprofessionals produced small effects that rarely achieved statistical or clinical significance; the absence of statistical significance for some outcomes is probably attributable to limited statistical power to detect small effects. Nurses produced significant effects on a wide range of maternal and child outcomes.

Background Accurate symptom evaluation is a critical component of asthma management. Limited data are available about the accuracy of symptom evaluation by children with asthma and their parents, or the impact of various symptom-monitoring strategies on asthma morbidity outcomes. Objective The purpose of this randomized clinical trial was to evaluate the effect of three different intensities of symptom monitoring on asthma morbidity outcomes. Methods One hundred sixty-eight children (ages 6 to 19) of diverse racial, geographic, and socioeconomic backgrounds were randomized to 1 of 3 treatment groups (subjective symptom evaluation, symptom-time peak expiratory flow rate (PEFR) monitoring, daily PEFR monitoring) in this longitudinal, clinical trial. Outcome measures included a summary asthma severity score, forced expiratory volume in 1 second, symptom days, and health care utilization. Results Children who used PEFR meters (PFMs) when symptomatic had a lower asthma severity score, fewer symptom days, and less health care utilization than children in the other two treatment groups. Minority and poor children had the greatest amount of improvement using PFMs when symptomatic. Results were much less striking in white families. Thirty percent of families in the PFM treatment groups discontinued use entirely by 1 year postexit, whereas the majority of families who continued use (94%) used them only when symptomatic to inform symptom interpretation and management decisions. Conclusions Not every child with asthma needs a PFM. Children and families facing extra challenges as a result of illness severity, sociodemographic, or health care system characteristics clearly benefited most from PFM use.

We evaluated a comprehensive program of prenatal and postpartum nurse home visitation. The program was designed to prevent a wide range of health and developmental problems in children born to primiparous women who were either teenagers, unmarried, or of low socioeconomic status. During pregnancy, women who were visited by nurses, compared with women randomly assigned to comparison groups, became aware of more community services; attended childbirth classes more frequently; made more extensive use of the nutritional supplementation program for women, infants, and children; made greater dietary improvements; reported that their babies' fathers became more interested in their pregnancies; were accompanied to the hospital by a support person during labor more frequently; reported talking more frequently to family members, friends, and service providers about their pregnancies and personal problems; and had fewer kidney infections. Positive effects of the program on birth weight and length of gestation were present for the offspring of young adolescents (less than 17 years of age) and smokers. In contrast to their comparison-group counterparts, young adolescents who were visited by nurses gave birth to newborns who were an average of 395 g heavier, and women who smoked and were visited by nurses exhibited a 75% reduction in the incidence of preterm delivery. (P less than or equal to .05 for all findings.)

Context. —Interest in home-visitation services as a way of improving maternal and child outcomes has grown out of the favorable results of a trial in semirural New York. The findings have not been replicated in other populations. Objective. —To test the effect of prenatal and infancy home visits by nurses on pregnancy-induced hypertension, preterm delivery, and low birth weight; on children's injuries, immunizations, mental development, and behavioral problems; and on maternal life course. Design. —Randomized controlled trial. Setting. —Public system of obstetric care in Memphis, Tenn. Participants. —A total of 1139 primarily African-American women at less than 29 weeks' gestation, with no previous live births, and with at least 2 sociodemographic risk characteristics (unmarried, Intervention. —Nurses made an average of 7 (range, 0-18) home visits during pregnancy and 26 (range, 0-71) visits from birth to the children's second birthdays. Main Outcome Measures. —Pregnancy-induced hypertension, preterm delivery, low birth weight, children's injuries, ingestions, and immunizations abstracted from medical records; mothers' reports of children's behavioral problems; tests of children's mental development; mothers' reports of subsequent pregnancy, educational achievement, and labor-force participation; and use of welfare derived from state records. Main Results. —In contrast to counterparts assigned to the comparison condition, fewer women visited by nurses during pregnancy had pregnancy-induced hypertension (13% vs 20%; P =.009). During the first 2 years after delivery, women visited by nurses during pregnancy and the first 2 years of the child's life had fewer health care encounters for children in which injuries or ingestions were detected (0.43 vs 0.55; P =.05); days that children were hospitalized with injuries or ingestions (0.03 vs 0.16; P P =.006). There were no program effects on preterm delivery or low birth weight; children's immunization rates, mental development, or behavioral problems; or mothers' education and employment. Conclusion. —This program of home visitation by nurses can reduce pregnancyinduced hypertension, childhood injuries, and subsequent pregnancies among low-income women with no previous live births.
