Burnout and Depression: Two Entities or One?

OBJECTIVES The purpose of this study was to examine the overlap in burnout and depression. METHOD The sample comprised 1,386 schoolteachers (mean [M]age = 43; Myears taught = 15; 77% women) from 18 different U.S. states. We assessed burnout, using the Shirom-Melamed Burnout Measure, and depression, using the depression module of the Patient Health Questionnaire. RESULTS Treated dimensionall...

Motoneuron double discharges: only one or two different entities?

INTRODUCTION The firing behavior of spinal motoneurons is controlled by a complex interplay between the synaptic inputs that they receive and the intrinsic properties of motoneurons. In particular, the longlasting afterhyperpolarization which follows each motoneuron spike was found to be an important mechanism in the regulation of repetitive firing behavior (Kernell, 1965, 2006). As a result, m...

Three-dimensional structure of dendritic spines in the rat neostriatum.

Dendritic spines of rat neostriatal neurons were examined by light microscopy and high voltage stereo electron microscopy (HVEM) following selective staining by intracellular microinjection of horseradish peroxidase. Conventionally prepared material also was used for quantitative analysis of dendritic spines from serial thin sections of neostriatum. Stereo electron microscopy of semithin sectio...

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
