BACKGROUND Although job satisfaction is among the most widely researched topics, relatively little research has been done on this issue as it relates to early childhood educators. This study was designed to contribute significantly to the deficient body of knowledge about working conditions and job satisfaction of day care teachers, in particular with regard to differences in job satisfaction d...

OBJECTIVES To determine the reasons for choosing between primary care out of hours centres and accident and emergency (A&E) departments for patients with primary care problems. METHODS Interviews using a semistructured approach of samples of patients attending A&E departments and general practitioner (GP) out of hours centres for primary care problems. RESULTS 102 patient interviews were un...

Automatic tube current modulation (TCM) is used in modern CT devices. This is implemented in the numerical calculation of dose conversion coefficients for CT examinations. For four models of adults, the female and male reference models of ICRP and ICRU and a lighter and a heavier female model, dose conversion coefficients normalized to CTDI(vol) (DCC(CT)) have been computed with a Monte Carlo t...

Although there have been several recent papers published on the results of day case surgery in children, little has been written on hospital-based day care for medical problems; in spite of this lack of information we believe many paediatric units provide this service. This paper describes our attempts to organize medical day cases on a general paediatric ward, and analyses some problems encoun...

Integrated behavioral health and primary care is emerging as a superior means by which to address the needs of the whole person, but we know neither the extent nor the distribution of integration. Using the Centers for Medicare and Medicaid Services’ National Plan and Provider Enumeration System (NPPES) Downloadable File, this study reports where colocation exists for (a) primary care providers...

Netrin-1 is a guidance cue that can trigger either attraction or repulsion effects on migrating axons of neurons, depending on the repertoire of receptors available on the growth cone. How a single chemotropic molecule can act in such contradictory ways has long been a puzzle at the molecular level. Here we present the crystal structure of netrin-1 in complex with the Deleted in Colorectal Canc...

During development, axons migrate long distances in responses to attractive or repulsive signals that are detected by their growth cones. One of these signals is mediated by netrin-1, a diffusible laminin-related molecule that both attracts and repels growth cones via interaction with its receptor DCC (deleted in colorectal cancer). Here we show that DCC in both commissural neurons and immortal...

The universe of current adult day care center administrators (n = 36) and a stratified random sample of child day care center administrators (n = 300) in Virginia were surveyed to gather information about professionals' perceptions of the benefits and problems associated with providing regular intergenerational exchanges in day care settings. Findings of a qualitative analysis revealed that pro...
