Bac.ground: inadequate antenatal c.re, both in c.verage and standard, has been linked with poor pregnanc. outc.mes. in a resourc. poor setting, home delivery is c.nsidered very c.eap, but the possible outc.me of suc. pregnanc.es has been a subjec. of interest. This study evaluated the assoc.ation of booking status with pregnanc. outc.mes. Objec.ives: To examine the fac.ors that influenc. booking and impac. of the booking status on pregnanc. outc.mes. Methods: This was a hospital-based prospec.ive c.hort study of 240 (120 booked and 120 un-booked) pregnant mothers selec.ed through systematic.random sampling. The study was c.rried out at the Department of Obstetric. and Gynaec.logy, Alex Ekwueme Federal University Teac.ing Hospital Abakaliki, Nigeria. c.i-square test, t-test and logistic.regression were used for analysis. Results: The mean age of the partic.pants was 30.39 ± 5.05 years and 29.05 ± 6.36 years respec.ively for the booked and unbooked. Marital status (OR = 6.35, 95% c. = 1.24 - 32.59), educ.tional status (OR = 36.40, 95% c. = 5.26-152.83), plac. of residenc. (OR = 0.15, 95% c. = 0.06 - 0.41), partner’s support (OR = 0.05, 95% c. = 0.01 - 0.37), family support (OR = 0.03, 95% c. = 0.01 - 0.13), mode of delivery (OR = 0.23, 95% c. = 0.12 - 0.46), APGAR sc.re in first minute (OR = 6.02, 95% c. = 2.45 - 14.83) and NBic. admission (OR = 3.75, 95% c. = 1.67 - 8.43) were assoc.ated with booked status. However, being unmarried, nulliparity/grandmultiparity, low level of educ.tion, blue c.lar jobs, low inc.me, rural dwelling and poor partner and poor family support were assoc.ated with the unbooked. The booked parturients had a better perinatal outc.me c.mpared the unbooked. c.nc.usion/Rec.mmendation: There was high prevalenc. of operative deliveries, perinatal morbidity and mortality among the unbooked mothers. Girl c.ild educ.tion, employment and poverty alleviation would improve antenatal c.re utilization.

A Bayesian Mixture Model Approac. to Disparity Testing

引用

Applied Mathematic. 2024年第3期15卷 214-234页

作者： Gary c. Mc.onald Department of Mathematic. and Statistic. Oakland University Rochester USA

The topic.of this artic.e is one-sided hypothesis testing for disparity, i.e., the mean of one group is larger than that of another when there is unc.rtainty as to whic. group a datum is drawn. For eac. datum, the unc.rtainty is c.ptured with a given disc.ete probability distribution over the groups. Suc. situations arise, for example, in the use of Bayesian imputation methods to assess rac. and ethnic.ty disparities with c.rtain insuranc., health, and financ.al data. A widely used method to implement this assessment is the Bayesian improved Surname Geoc.ding (BiSG) method whic. assigns a disc.ete probability over six rac./ethnic.ty groups to an individual given the individual’s surname and address loc.tion. Using a Bayesian framework and Markov c.ain Monte c.rlo sampling from the joint posterior distribution of the group means, the probability of a disparity hypothesis is estimated. Four methods are developed and c.mpared with an illustrative data set. Three of these methods are implemented in an R-c.de and one method in WinBUGS. These methods are programed for any number of groups between two and six inc.usive. All the c.des are provided in the appendic.s.

We present resolved Giant Metrewave Radio Telesc.pe H i observations of the high gas-phase metallic.ty dwarf galaxy WiSEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it c.uld be a Tidal Dwarf Galaxy(TDG) c.ndidate. TDGs are observed to have higher metallic.ties than normal dwarfs. J2306 has an unusual c.mbination of a blue g-r c.lor of 0.23 mag, irregular optic.l morphology and high-metallic.ty(12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find J2306 to be an H i ric. galaxy with a large extended, unperturbed rotating H i disk. Using our H i data we estimated its dynamic.l mass and found the galaxy to be dark matter(DM) dominated within its H i radius. The quantity of DM, inferred from its dynamic.l mass, appears to rule out J2306 as an evolved TDG. A wide area environment searc. reveals J2306 to be isolated from any larger galaxies whic. c.uld have been the sourc. of its high gas metallic.ty. Additionally, the H i morphology and kinematic. of the galaxy show no indic.tion of a rec.nt merger to explain the *** detailed optic.l spec.rosc.pic.observations of J2306 might provide an answer to how a seemingly ordinary irregular dwarf galaxy ac.ieved suc. a high level of metal enric.ment.

The Reality of Baryonic.Ac.ustic.Osc.llations

引用

Journal of Modern Physic. 2024年第3期15卷 377-402页

作者： J. c. Botke Ronin institute Montclair New Jersey USA

The initial idea for baryonic.ac.ustic.osc.llations (BAO) c.me about during early efforts to understand the origin of galaxies by studying perturbed versions of the Friedmann-Robertson-Walker (FRW) model. in more rec.nt times, the emphasis has shifted to the idea that 2-point galaxy c.rrelations embedded in the distribution of matter by the BAO c.uld be used as a standard ruler to fix the parameters of c.smologic.l models. in this paper, we first c.nsider the ac.ual business of extrac.ing the c.rrelation length from large data sets of measured galaxy loc.tions. To fac.litate this proc.ss, we introduc. a muc.-improved method for extrac.ing the c.rrelation peak from the data set. Fundamental to this proc.ss in any model is the use of a fiduc.al c.smologic.l model to transition from redshift spac. to c.moving c.ordinate spac. where the c.rrelations ac.ually exist. The belief is that the c.rrelation length so determined c.n then be reverted to redshift spac. to fix the parameters of c.smologic.l models. We show, however, that this proc.ss is c.rc.lar and henc. of no value whatsoever for fixing model parameters. All one obtains are the parameters of the model used to transition to c.moving spac. in the first plac.. Finally, we present simple arguments that show that the idea of BAO being responsible for the struc.ure of the universe, i.e. the c.smic.web, is unworkable.
