Individual Differences in (Non-Visual) Processing Style Predict the Face Inversion Effect
Recent research suggests that individuals with relatively weak global precedence (i.e., a smaller propensity to view visual stimuli in a configural manner) show a reduced face inversion effect (FIE). Coupled with such findings, a number of recent studies have demonstrated links between an advantage for feature-based processing and the presentation of traits associated with autism among the general population. The present study sought to bridge these findings by investigating whether a relationship exists between the possession of autism-associated traits (i.e., as indicated by individualsautism quotient [(AQ) and the size of the FIE. Participants completed an on-line study in which the AQ was measured prior to a standard face recognition task where half of the faces were inverted at test. The results confirmed that higher AQ levels were predictive of smaller FIEs. Implications for a common underlying factor relating to processing orientation are discussed
Heart diseasae in pregnancy
A series of two hundred and twenty -five patients
with heart disease is reviewed, showing its incidence
in pregnancy to be 0.8 per cent, and its mortality
3.1 per cent.With better obstetrics and fewer deaths from
sepsis, heart disease is occupying a relatively more
prominent position as a cause of maternal deaths,
being the fourth most common cause in this series,
and accounting for 11.6 per cent of all maternal
deaths.Rheumatic fever was responsible for 93 per cent
of cases, and the mitral valve was the site of the
lesion in all but a few.Observation of patients with heart disease at
weekly intervals is recommended, owing to the danger
of their condition deteriorating and in order
immediately to observe any adverse change: and it is
recommended that all patients should be admitted for
one week about the twenty- eighth week, for rest and
assessment, and again seven to ten days before full
term. Antenatal care is one of the major factors
in lowering the mortality rate, and each visit of the
patient should include careful medical examination,
especially of her lung bases for the early crepitations, close questioning as to her daily routine and an assurance that she keeps within the limits of her
cardiac reserve. It is possible that the more
frequent examination and earlier advice and treatment
of the Group II patients may be the key to the
avoidance of the occasional failure in this group.Respiratory infections, however trivial, have
to be treated seriously, as they have a tendency to
resist ordinary treatment and may precipitate.heart
failure; anaemia, too, should be avoided, and, if
marked, a careful look-out kept for signs which might
suggest subacute endocarditis, and the patient should
be advised to report should she develop any new
symptom.The functional heart grouping of the American
Heart Association gives a good indication of the
cardiac reserve, and offers a common nomenclature for
reporting results.Some additional factors in assessment in individual cases, as suggested by Lamb (1934), may help
to lessen the dangers of cardiac decompensation and,
towards this end, the co- operation between the
cardiologist and the obstetrician is essential.A history of previous failure is a bad prognosti
sign, and, although there is an apparent recovery,
such patients should be regarded as group IV cases.
It may, in fact, be advisable, as regards the
obstetric treatment, to place the patient in the least favourable group to which she may have reached, no
matter what the improvement obtained with treatment,
or what more favourable group she may later occupy
during pregnancy.Spontaneous labour, aided, if necessary, by forceps,
would seem to be the best mode of delivery, and
is possible in the vast majority of cases; Caesarean
section being reserved for the presence of other
obstetrical complications, or, in some cases, where
surgical termination of the pregnancy is indicated.It has been noted in this series, that patients
with heart disease do not stand up well to prolonged
labour or to accouchement force, and, if these are
anticipated, a Caesarean section may be less of a risk
to the patient. Observation of the pulse and respiration
rates during the first stage of labour, as
recommended by Mendelson and Pardee (1942), and
immediate digitalisation, if necessary, may serve to
prevent decompensation developing.The anaesthetic which is best advised is morphia
for the first stage and pudendal block for the second
stage of labour, supplemented by a light gas and
oxygen and episiotomy when forceps are used.There is a definite place for therapeutic abortion
in the group III and IV patients; and in others,
rho have given a history of previous heart failure,
it is assessed individually.The selection of bad-risk cardiac patients
should be one at cardiac clinics, where they should
be advised against becoming pregnant: and this precaution
together with careful choosing of patients
who are to proceed with pregnancy and avoid decompensation,
with its attendant risks, can serve
greatly to lower the mortality rate. Gilchrist and
Murray Lyon (1933) say that one or two pregnancies do
not shorten the expectation of life in the cardiac:
and Jones (1944) advises against a third pregnancy.
These observations have shown, however, that, altho
pregnancy may not induce heart failure, it may leave
the heart severely crippled. It has been shown in
this series that patients who have changed to a less
favourable functional heart group during pregnancy
are more liable to show these adverse effects in
later years. No difference, however, in the age of
death has been shown in nulliparous and parous women.Of congenital lesions, unless there is persistent
cyanosis, which would justify advising against
pregnancy, or securing an early termination, the
patient is treated as for other heart lesions: the
exception being in those lesions where excess
straining must be avoided and when, therefore, a
Caesarean section should be performed.A guarded prognosis has to be given until the
end of the puerperium, since the majority of
fatalities occur then, and additional rest in
hospital should be advised for patients at this time.Before the patient leaves hospital, to assume the
extensive burdens of the care of her child, a full
opportunity should be taken to discuss with her the
domestic responsibilities which she has to meet:
and if indicated, as it is in most cases, arrangements
made whereby she may have the assistance of a
Home-help, such as is now available from most local
Authority Departments. Finally, a date is given to
the patient for attendance at a Cardiological clinic
for future advice and guidance
CAREER: The Role of Microorganisms in Arsenic Contamination of Groundwater
Arsenic is the only contaminant for which exposure through drinking water has been proven to cause cancer in humans. The US Environmental Protection Agency has concluded that the present drinking water limit of 50 ug/L arsenic is not sufficiently protective and proposes a new limit of 10 ug/L. In most cases, the arsenic originates in the geologic materials of the aquifer. While correlations with bedrock types have been made, the factors that affect arsenic concentrations and speciation in drinking water are poorly understood. As(III), the reduced inorganic form, is more mobile and more toxic than As(V), thus speciation affects both the concentration and the health implications of arsenic exposure. Microorganisms probably affect As concentrations in groundwater, but the magnitude and nature of their participation in the arsenic cycle have not yet been clarified. Microorganisms can affect the chemistry of arsenic compounds in a number of ways. Laboratory and field studies as proposed in this program will build on the PI\u27s preliminary data that indicate the presence of arsenate reducing microorganisms in well water to determine how microbial activities affect soluble arsenic concentrations. This information will be used to create a conceptual model of the processes that affect As in groundwater. Molecular probes will be developed to determine the importance of the isolated arsenate-degrading microorganisms in situ. Existing geological data and field data gathered by high school and undergraduate students will be used to assess whether or not the model derived from laboratory experiments is supported by field observations. Since the project requires an interdisciplinary approach, links with microbial ecologists and environmental microbiologists will be strengthened to support the investigator\u27s research goals. The research results will form the basis of new modules in two undergraduate environmental engineering courses. An outreach program for high school students will also contribute to the collection of field data
Making co-enrolment feasible for randomised controlled trials in paediatric intensive care.
Enrolling children into several trials could increase recruitment and lead to quicker delivery of optimal care in paediatric intensive care units (PICU). We evaluated decisions taken by clinicians and parents in PICU on co-enrolment for two large pragmatic trials: the CATCH trial (CATheters in CHildren) comparing impregnated with standard central venous catheters (CVCs) for reducing bloodstream infection in PICU and the CHIP trial comparing tight versus standard control of hyperglycaemia
Optical frequency generation using fiber Bragg grating filters for applications in portable quantum sensing
A method for the agile generation of the optical frequencies required for
laser cooling and atom interferometry of rubidium is demonstrated. It relies on
fiber Bragg grating technology to filter the output of an electro-optic
modulator and was demonstrated in a robust, alignment-free, single-seed,
frequency-doubled, telecom fiber laser system. The system was capable of 50 ns
frequency switching over a ~40 GHz range, ~0.5 W output power and amplitude
modulation with a ~15 ns rise/fall time and an extinction ratio of 120 2
dB. The technology is ideal for enabling high-bandwidth, mobile industrial and
space applications of quantum technologies
