Presence Of A Cs-Resistant Transient Outward Current Which Distorts Ica Measurements In Guinea-Pig Single Ventricular Cells, Georges Christé, Brigitte Delachapelle, Fouad Lemtiri-Chlieh, Carlos Ojeda

fouad Lemtiri-Chlieh

To correctlyr analyse the physical properties of ion channels and the actions of drugs upon them, it is important that the membrane conducts only the ionic species believed permeant. In guinea-pig ventricular cells it has been assumed that only ICaL flows in the potential range -50 to +60 mV in the presence of intra- and extracellular Cs (> 20 mM). We report here that this is not the case due to the presence of a Cs-insensitive, transient outward current.

Measurements Of Cytosolic Free Ca In Cultured Rat Neonate And Adult Guinea-Pig Ventricular Cardiac Myocytes, Jean-Claude Bernengo, Fouad Lemtiri-Chlieh, Carlos Ojeda, Nadine Pltonoff

fouad Lemtiri-Chlieh

Cytosolic free Ca was measured with Indo-1 (Grynkiewicz et al. 1985) as free acid (in guinea-pig cells) or as the ester (in rat neonate cells). Using image analysis we obtained concentration maps at 40 ms intervals at two wavelengths (Cannell et al. 1986). In rat neonate cells, at rest and during contraction, calcium was apparently non-uniformly distributed, in contrast to guinea-pig adult cells. Using a dual PM spectroscopic system adapted to an inverted microscope we found: (1) the conversion of Indo-AM to Indo- 1 in the cytosol is not complete (< 40% contribution to the total light); (2) rat neonate cells buffer Ca (at rest 130-170 nM) only for [Ca]. between 1 and 3 mM, whereas in adult guinea-pig cells the range extended to 10 mM; (3) during contraction [Ca]i rose from 200 nm to no more than 1 microM. Digitoxin increases basal and peak [Ca]i; (4) during spontaneous contractions, in guinea-pig cells, [Ca]i rises from 70 to 200 nm when [Ca]o = 0, and from 170 nm to about 1 microM when [Ca]o = 2 mM; (5) in voltage-clamp conditions the rise in [Ca]i does not exceed 2 microM and oscillations occur in the presence of forskolin. When loading with Indo-1, cells frequently cease to contract (Powell et al. 1988) and the variations in [Ca]i are then very small (about 200 nm at peak ICa). In both cases these values are small compared to the total charge crossing the membrane.

Treatment Modality And Quality Differences For Black And White Breast Cancer Patients Treated In Community Hospitals, Paula Diehr

Paula Diehr

This study assessed the relationship of race and patterns of care, defined by an expert NCI-appointed committee, for 7,781 patients with breast cancer treated in 107 hospitals in 45 communities between 1982 and 1985. After control for age and stage of disease, black patients had significantly different care from white patients for four of the ten patterns examined. They were less likely to have a progesterone receptor assay or to be referred for postmastectomy rehabilitation, two patterns deemed desirable for all patients. Black patients were also more likely to receive liver scans and radiation therapy in situations in which these …

El Municipio Y La Organización Del Estado En Ecuador, Fernando Carrión Mena

Fernando Carrión Mena

El proceso de urbanización en el Ecuador se rige por la lógica concentradora y excluyente, propia del tipo de desarrollo capitalista en nuestras naciones, se expresa entre otras cosas, en la desarticulación de la red urbana, el ilimitado crecimiento de las ciudades grandes por sobre el resto de los asentamientos humanos, la profundización de los desequilibrios y desigualdades a todo nivel (social, intraurbano y ecológico), el predominio de la población urbana sobre la rural, etc.

Esta expresión fenoménica de la urbanización ecuatoriana tiende a acrecentarse desde los años sesenta y con mayor énfasis desde el "boom petrolero" en 1972. Ello …

Cooperation In A Repeated Prisoner's Dilemma With Ostracism, Eric Bennett Rasmusen, David Hirshleifer

Eric Bennett Rasmusen

The unique Nash equilibrium of the finitely repeated n-person Prisoners' Dilemma calls for defection in all rounds. One way to enforce cooperation in groups is ostracism: players who defect are expelled. If the group's members prefer not to diminish its size, ostracism hurts the legitimate members of the group as well as the outcast, putting the credibility of the threat in doubt. Nonetheless, we show that ostracism can be effective in promoting cooperation with either finite or infinite rounds of play. The model can be applied to games other than the Prisoners' Dilemma, and ostracism can enforce inefficient as well …

How A Personal Document's Intended Use Or Purpose Affects Its Classification In An Office., Barbara H. Kwasnik

Barbara H. Kwasnik

This paper reports on the findings of a larger case study that attempts to describe how people organize documents in their own offices. In that study, several dimensions along which people make classificatory decisions were identified. Of these, the use of to which a document is put emerged as a strong determiner of that document’s classification. The method of analysis is reviewed, and examples of the different kinds of uses are presented, demonstrating that it is possible to describe a wide variety of specific instances using a closed set of descriptors. The suggestion is made that, in designing systems for …

Product Quality With Information Dissemination And Switching Costs, Eric Bennett Rasmusen

Eric Bennett Rasmusen

Klein and Leffler (1981) construct a model in which expected future prices exceed marginal costs so that sellers are willing to maintain high quality for the sake of future profits. How profits are dissapated under free entry, and whether there is a continuum of equilibria, are questions not fully resolved. I contstruct a formal model simpler than any now existing in which free entry and exogenous fixed costs uniquely determine the price of output and the amount sold per firm.

Relations Between Work And Life Away From Work Among University Faculty, Mary Deane Sorcinelli, Janet P. Near

Mary Deane Sorcinelli

As one aspect of a study on faculty career development, relations between work and life away from work were explored for one hundred and twelve faculty. Analyses focused on the degree to which experiences and/or feelings associated with work directly colored or "spilled over" to life outside of work and vice versa. Differences by gender and rank also were examined.

Confirmation Of The Structural Dimensionality Of The Stanford-Binet Intelligence Scale (Fourth Edition), Gregory J. Boyle

Gregory J. Boyle

The new Stanford-Binet Intelligence Scale (fourth edition) seemingly represents an important advance in design and construction over the earlier form L-M. The latest version of the instrument (SB-IV) is purported to index both crystallized intelligence (Verbal and Quantitative Reasoning Areas) and fluid intelligence (Abstract/Visual Reasoning Area) structural dimensions respectively. Given the prominence of modem information­ processing theories of cognition, a separate Short-Term Memory (STM) Area is also provided. The authors provided confirmatory factor analytic (CFA) evidence to support their claim for the construct validity of each of the four cognitive ability areas. However, several inconsistent factor loadings were apparent, for …

Factor Structure Of The Differential Emotions Scale And The Eight State Questionnaire Revisited, Gregory J. Boyle

Gregory J. Boyle

The Differential Emotions Scale (DES-IV) and the Eight State Questionnaire (SSQ) are two separately developed multidimensional instruments purported to index simultaneously a number of fundamental emotional/mood states. The two instruments combined quantify some 20 primary mood states, which, in practice, may provide too complex a picture to be of benefit in many applied and research settings. Attempts to derive higher-order mood-state factors from both the DES-IV and the SSQ have yielded somewhat inconsistent results. In. this paper an attempt was made to resolve this issue by reanalysing data collected from 450 Australian tertiary college students. The results indicated that there …

Anomaly In Equation For Calculating 16pf Second Order Factor Qiii, Gregory J. Boyle

Gregory J. Boyle

Recently, the Institute for Personality and Ability Testing (IPAT) has released a new set of equations for calculating 16PF second-order factors. These revised equations were compared with the earlier ones provided in the l6PF Handbook, as well as with those used in the Clinical Analysis Questionnaire (CAQ) for computing the second-order trait dimensions. It was found that the earlier 16PF Handbook equation for calculating QIII (Tough Poise) was not accurate. It is recommended that only the new equations be employed in future work with the 16PF. Moreover, this finding may have implications for published studies involving the 16PF second-order factors …

Sex Differences In Reported Mood States, Gregory J. Boyle

Gregory J. Boyle

It is generally agreed that females tend to assent more readily to negative mood states such as Anxiety or Depression, than do males. The present study explored this issue on a large sample of male and female Education undergraduate students, using the Eight State Questionnaire (8SQ) as the measure of mood states. Several studies had previously suggested that the 8SQ is a useful multidimensional instrument for quantifying a wide range of clinically important mood states. Results indicated that male and female students responded differentially to a minority of the 8SQ items, and that the factor structure of reported moods differed …

Comparison Of Higher Stratum Motivational Factors Across Sexes Using The Children's Motivation Analysis Test, Gregory J. Boyle, K B. Start

Gregory J. Boyle

The Children's Motivation Analysis Test (CMAT) is a newly developed objective instrument for quantifying several important motivational dynamic traits among primary school children. The CMAT is a downward extension of the MAT and SMAT instruments, which have put motivation measurement onto a new level of sophistication. These pencil-and-paper instruments avoid the most serious handicap of self-report questionnaires, namely the obvious transparency of items, and concomitant ease of faking good or faking bad, as well as other kinds of response distortion which may result from inadequate self-insight of one's motivational attributes. The CMAT was administered to separate groups of male and …

Dimensions Of Adolescent Motivation As Measured By Higher-Order Factors In The School Motivation Analysis Test, Gregory J. Boyle, K Brian Start, E John Hall

Gregory J. Boyle

Although previous analyses of higher-order motivational dimensions have suggested at least seven major dynamic traits among adults, corresponding analyses among adolescents have not yet been undertaken in any satisfactory manner. To this end, the present article reports the results of a higher-order factor analysis of the subscale intercorrelations for the School Motivation Analysis Test (SMAT) on an Australian sample of 277 Year I 0 students enrolled in various senior high schools. The results suggest that at least six factors maximally account for the common variance in the SMAT. Tentative interpretations of the higher-order factors obtained are made and discussed in …

Prediction Of Academic Achievement Using The School Motivation Analysis Test., Gregory J. Boyle, Brian K. Start, John E. Hall

Gregory J. Boyle

Mathematics and English achievement was investigated among 277 Year 10 Australian students. Using the School Motivation Analysis Test (SMAT) as the measure of dynamic motivational traits, significant achievement variance (25 percent for Mathematics; 34 percent for English) was accounted for independently from that due to abilities and personality traits. Male students tended to invest a greater proportion of intellectual abilities (indexed via the SMAT General Information Intelligence score) than did females in the learning of Mathematics (accounting for 25 percent of the variance for males), whereas females demonstrated a higher investment of abilities in English. The specific motivational dynamic traits …

Sex Differences In The Prediction Of Academic Achievement Using The Children's Motivation Analysis Test, Gregory J. Boyle, Brian K. Start

Gregory J. Boyle

The Children's Motivation Analysis Test (CMAT), together with standardised achievement tests in mathematics and reading, was administered to a large sample of Australian elementary school children. Stepwise forward regression analyses were conducted on subsamples of 209 males and 179 females (cases with missing data previously excluded). Several of the CMAT dynamic traits significantly predicted achievement scores. The most useful predictors were conscientiousness (Superego) and family (Home) orientation. These results, based on objective motivation measurement, represent the beginnings of a new approach for research into children's motivation structure.

Are Employment-Interview Skills A Correlate Of Subtypes Of Schizophrenia?, James Charisiou, Henry J. Jackson, Gregory J. Boyle, Philip Burgess, Harry I. Minas, Stephen D. Joshua

Gregory J. Boyle

46 inpatients with a DSM-III diagnosis of schizophrenia were assessed in the week prior to discharge from hospital on measures of positive and negative symptoms and on 12 measures of employment interview skills (i.e., eye contact, facial gestures, body posture, verbal content, voice volume, length of speech, motivation, self-confidence, ability to communicate, manifest adjustment, manifest intelligence, over-all interview skill), and a global measure of employability. A cluster analysis based on the total positive and negative symptom scores produced two groups. The group with the lower mean negative symptom score exhibited better employment-interview skills and higher ratings on employability.

Dissipative Model Of The Universe, Milan Meszaros

Milan Meszaros physicist

In the present study a trial is carried out to generalize the non-relativistic-dynamic model of cosmology put forward by O. Heckmann. The generalization is performed under the framework of the Gyarmati principle of irreversible thermodynamics for anisotropic inhomogeneous and viscous case. The equation of motion of the dissipative Universe will be a Navier-Stokes tensor equation leading to a Riccatian differential equation general in one dimension. The equations of the Heckmann model compatible with standard cosmology can be obtained from this by means of further simplifying assumption.
