Substituting Symbol Search for Coding on the WISC-III: Canadian normative tables for Performance and Full Scale IQ scores.

A. S. Kaufman (1994) recommends that the Symbol Search, an optional subtest to the WISC-III, be substituted for Coding in the calculation of WISC-III Performance and Full Scale IQ scores. Conversion tables have been published for use with American norms. The authors provide conversion tables for the Canadian-normed WISC-III. The standardization sample consisted of a representative group of 1,100 English-speaking Canadian children. The conversion tables are provided. These tables allow Canadian WISC-III examiners to substitute Symbol Search for Coding in the calculation of the Performance and Full Scale IQ scores.

The detection of the sleep apnea syndrome in a population of professional drivers

The aim of this study was to reduce the risk of traffic accidents related to obstructive sleep apnea syndrome (OSAS) by means its detection and treatment in a group of 100 commercial drivers from Seville. Besides, to analyze which clinical findings could suggest OSAS. By means a questionnaire we selected subjects without (questionnaire score < 10 points) and with (questionnaire score > or = 10) clinical history of OSAS. In cases with score > or = 10, an overnight home polygraphy was carried out (Apnoescreen II, Jaeger), with measurement of oronasal airflow, chest and abdominal movements, oxygen saturation, electrocardiogram, body position and actimetry. We performed a manual analysis of recordings, and polygraphy was considered to be positive for OSAS if both AHI (respiratory events Index) or DI (desaturation Index) were > or = 10. In these positive cases, overnight conventional polysomnography was carried out (SleepLab, Jaeger), with therapeutic tests with CPAP if OSAS was diagnosed (AHI > or = 10). Average age and BMI (Body Mass Index) were 41.5 +/- 0.9 years and 28.2 +/- 0.4 kg/m2. Questionnaire was positive in 59 subjects, in 35 of whom home polysomnography was done. We did not find differences in age, BMI, neck circumference or symptomatology among these 35 drivers and the 24 remaining subjects in whom home polygraphy was not performed. Home polygraphy was positive in 10 subjects and negative In 25. Drivers in first group were older, heavier and complaint more frequently about snoring, sleep apnea and daytime sleepiness. We did not find differences in neck circumference, waist/hip ratio nor alcohol consumption between both groups. From the group with positive polygraphy, we performed conventional polysomnography in 8 cases and OSAS was diagnosed in 5 (in all cases, treatment with CPAP was started). This study does not provide data about prevalence, but it seems that the percentage of our drivers with OSAS could be lightly higher than the prevalence in general population. These subjects seem to be older, heavier and complaint more frequently about snoring, sleep apnea and daytime sleepiness.     

Lowpass minimum phase filter design using IFIR filters

A design procedure for minimum-phase FIR filters using an interpolated FIR (IFIR) filter is proposed. The IFIR technique allows two linear-phase filters of much lower order to be designed thereby making it easier to apply mipizing than is possible in high order FIR prototype filters. In this way, the problem of finding the roots of high order polynomials is overcome     

Environmental Legionella Assessment in Office Buildings Of Continental United States

An environmental assessment of Legionella bacteria was conducted in five office buildings in the continental United States where no legionellosis was reported. The purpose of this investigation was to (i) determine the presence of Legionella bacteria in potable and non-potable water systems, (ii) provide a baseline information for management, and (iii) evaluate the effectiveness of the remedial actions taken. Water samples were collected from all possible water sources in surveyed buildings. The samples were analyzed by both direct fluorescent antibody microscopy (DFA) and the bacterial cultural method for the presence of Legionella species. Legionella bacteria were detected in some samples collected from various water distribution systems in the buildings. Remedial action was taken to eliminate these bacteria, and case-by-case results are presented.     

Water,Energy and Environment Nexus: The California Experience

The paper addresses the local and inter-state connections between water, energy and the environment. Using California and the western USA as a case study, the paper highlights the difficulties of balancing the needs of diverse stakeholders and protecting valuable resources while providing reliable and safe supplies of both water and energy to agricultural, industrial and residential customers. The investigation of these complex relationships is necessary to inform local and national policy decisions regarding the management of water, energy and the environment.     

Gender differences in partner violence in a birth cohort of 21-year-olds: Bridging the gap between clinical and epidemiological approaches.

This study describes partner violence in a representative sample of young adults. Physical violence perpetration was reported by 37.2% of women and 21.8% of men. Correlates of involvement in severe physical violence differed by gender. Severe physical violence was more strongly associated with unemployment, low educational attainment, few social support resources, polydrug use, antisocial personality disorder symptoms, depression symptoms, and violence toward strangers for men than for women. Women who were victims of severe physical violence were more likely than men who were victims to experience symptoms of anxiety. The findings converge with community studies showing that more women than men are physically violent toward a partner and with clinical studies highlighting violence perpetrated against women by men with deviant characteristics.

Kinetic study of the sulfurisation of cuprous halides in hydrogen sulfide. Cuprous bromide and iodide

The sulfurisation of cuprous bromides and iodides in hydrogen sulfide, at low pressure, leads to the formation of a porous chalcosine layer, as already investigated in the case of chlorides. The step which fixes the conversion rate is the diffusion of the gaseous reagents in the pores of the sulfide formed. Experimental activation energies are 15 and 34 kcal.Mole^?1 respectively, at every step of the reaction.     

Preoptic area and substantia nigra interact in the control of maternal behavior in the rat.

Investigated the influence of the lateral connections of the medial preoptic area (MPOA) on maternal behavior via the substantia nigra (SN). In Exp I, conducted with 45 postpartum lactating Charles River CD rats, the effects of large and small bilateral electrolytic lesions of SN were investigated. Large lesions severely disrupted maternal behavior and caused stereotyped activity in Ss. A 2nd experiment employed an asymmetrical lesion design and 37 Ss. Ss that received a unilateral knife cut severing the lateral connections of the MPOA and a contralateral lesion of the SN showed larger deficits in maternal behavior than either sham Ss or Ss that received a unilateral preoptic cut paired with an ipsilateral SN lesion. Measurements of body weights, body temperatures, and stereotyped behavior indicated that the differences in maternal behavior between the ipsilateral and contralateral groups could not be explained on the basis of nonspecific effects.

Clarification of publishing history of Park, Morrell, Frieske, and Kincaid.

Readers and secondary services are alerted that, through no fault of her own, two nearly identical articles by Denise C. Park have been published. A full report of the research appeared in the American Psychological Association publication, Psychology and Aging. The full reference follows: Park, D. C., Morrell, R. W., Frieske, D., & Kincaid, D. (1992). Medication adherence behaviors in older adults: Effects of external cognitive supports. Psychology and Aging, 7,252-256 (see record 1992-36400-001). Although Dr. Park expressly denied in writing to the conference editors permission to publish the full text of the paper in the conference proceedings, the full text nonetheless was published as follows: Park, D.
