An analysis of dairy herd records to determine the cause of low reproductive efficiency usually leads to the conclusion that problems are centered in one of the following areas: breeding policy (intentionally waiting too long after calving for first service), estrous detection efficiency (missed heats), or conception rate. The challenge is to identify the factors responsible for the problem. On...

INTRODUCTION Safer conception care encompasses HIV care, treatment and prevention for persons living with HIV and their partners who desire children. In 2012, South Africa endorsed a progressive safer conception policy supporting HIV-affected persons to safely meet reproductive goals. However, aside from select research-supported clinics, widespread implementation has not occurred. Using South ...

Of the relatively few emergency calls made upon you in practice, the call for treatment of the acute attack of asthma will be by far the most common. In fact with some patients the calls become so frequent and at such inconvenient moment that both the doctor and his patient begin to meet with ill grace. The late Wilfred Trotter in an address on emergencies said this: "In a certain sense of the ...

My purpose here is to describe and defend a programme in social ontology. It is a programme being carried though by a group of researchers in Cambridge. I start by defining some of my terms. Ontology The term ontology 2 derives from Greek, with " onto " meaning " being " , and " logos " usually interpreted as " science " ; so that ontology, as traditionally understood, is the science or study o...

The objective of this study was to compare average stress levels during the month of conception to those of previous infertile months. We postulated that stress level during the actual month of conception would be lower than that during previous non-conception cycles. Thirteen normal women from the general community, who were attempting pregnancy, kept daily records of coital activity and basal...

OBJECTIVE To study the processes by which donor-conceived children incorporate donor conception into their subjective sense of identity. DESIGN Cross-sectional. SETTING Family homes. PATIENT(S) Nineteen donor-conceived adolescents. INTERVENTION(S) Administration of an interview and questionnaire. MAIN OUTCOME MEASURE(S) The mother-child relationship was assessed through the Friends an...

In this paper we study a combinatorial optimization problem arising from on-board networks in satellites. In these kinds of networks the entering signals (inputs) should be routed to amplifiers (outputs). The connections are made via expensive switches with four available links. The paths connecting inputs to outputs should be link-disjoint. More formally, we call a (p, λ, k)−network an undirec...

PERHAPS NO TECHNICAL TERM more aptly distinguishes psychoanalytic technique from other forms of psychotherapy than the word "neutrality." Yet, Freud didn't even introduce the term until 1915—some twenty years after his basic theory and treatment philosophy were established. Since its introduction in the last of Freud's six papers on technique, "Observations on Transference-Love" (1915), the app...

Based on the conception of total teacher effectiveness, aims to develop strategies for conceptualizing teacher effectiveness research. From the new conception, the units of research on teacher effectiveness are cell, array and layer. The strategies advanced for conceptualizing research include the individual unit description strategies, the within-layer relationship strategies, the betweenlayer...
