Is millennium development goal 4 achievable in Tanzania?
(WB Saunders, 2013)Introduction: This paper will focus on MDG4, which is concerned with reducing child mortality. Childhood mortality rates are the leading indicator of the level of child health and overall development of a country; and ... -
A comparative analysis of contraceptive use in Africa: evidence from DHS
(SAGE Publications, 2016)The aim of this article is to show a comparative analysis of contraceptive use in areas of traditionally high fertility that have gone through profound changes. Data have been taken from the latest Demographic and Health ... -
Understanding issues of people living with disabilities in South Africa
(SAGE Publications, 2013)The problem of disabilities is growing all over the world. Nevertheless, some progress has been made since the year 1981 was proclaimed International Year of Disabled Persons. In 2001 people living with disabilities accounted ... -
Son preference and contraceptive practice among tribal groups in rural South India
(Kamla-Raj Enterprises, 2006)This paper examines the son preference and contraceptive practice among tribal groups in rural south India. Parents’ preferences for the sex of their children have constituted an important theme in population and social ... -
Maternal mortality in Burkina Faso: a method from population census 2006
(Tehran University of Medical Sciences, 2013)Background: Estimating maternal mortality level is constantly challenging researchers and planners both in rich and poor countries. In developing countries, particularly in Burkina Faso where the registration system is not ... -
Work participation and disabilities in India
(Kamla-Raj Enterprises, 2009)United Nations General Assembly in 1976 proclaimed 1981 as the International Year of the Disable Persons. Persons with disabilities are enthusiastic to overcome the social and economic barriers. In the present paper an ... -
Child mortality rate in Ethiopia
(Tehran University of Medical Sciences, 2012)Ethiopia’s childhood mortality has continued to decline although at a swift pace. The drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends ... -
Correlates of antenatal and postnatal care among tribal women in India
(Kamla-Raj Enterprises, 2012)It is well established that those women who undergo full antenatal care check-up and give birth in a medical institution or whose delivery is attended by trained paramedical persons promotes child survival and reduces ... -
Under-5 Mortality in Tanzania: a demographic scenario
(Tehran University of Medical Sciences, 2012)Background: The government of the United Republic of Tanzania has initiated the Integrated Management of Childhood Illness program to improve the health and wellbeing of children. Methods: Tanzania’s under-five mortality ... -
The “four sigma” limit for significant periodicities
(Springer Verlag, 2010)Most of the pulsations which have been observed in sdB stars have very low amplitudes. Detection of modes from photometric observations is usually performed by noting the most prominent peaks in a periodogram or, ... -
Simulation of Y-chromosomal haplotype data
(Elsevier, 2010)The non-recombining nature of the Y-chromosome determines the non-independence of alleles between loci. The evolution of short tandem repeat (STR) loci in the Y-chromosome is the result of different factors such as ... -
UBV(RI)C photometry of transiting planet hosting stars
(Oxford University Press, 2011)We present new UBV(RI)C photometry of 22 stars that host transiting planets, 19 of which were discovered by the Wide Angle Search for Planets (WASP) survey. We use these data together with Two Micron All Sky Survey (2MASS) ... -
A re-assessment of the nearest neighbour alignment of the X-ray isophotes of galaxy clusters
(Oxford University Press, 2006)Alignment is defined as the tendency of the distribution of pointing angles between the major axes of clusters and their nearest neighbours to be more concentrated towards small values for small nearest neighbour distances, ... -
Deaf telephony: community-based co-design (case study)
(Wiley, 2011)The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ... -
KPD 0629–0016, a slowly pulsating hot subdwarf star
(Oxford University Press, 2007)The results of nine CCD photometric observing runs on KPD 0629–0016 are presented. During six of the runs measurements were obtained alternately through B and V filters. Four periodicities, for which there is good agreement ... -
Linking multi-epoch CCD photometry of partially overlapping fields
(Oxford University Press, 2013)A common problem in CCD photometry is to combine measurements obtained at different epochs. This is especially challenging if the fields only overlap partially, and are sparse, so that not all calibrating stars are ... -
JL 82: a slowly pulsating hot subdwarf star in a close binary system
(Oxford University Press, 2009)JL 82 is a known binary, consisting of an sdB star and a companion which is not directly observable in the optical. Photometric measurements reported in this paper show it to variable with both the binary period (∼0.75 ... -
Multiple regression of GRB luminosity on light-curve properties
(Oxford University Press, 2009)Statistical relations between the luminosity L of gamma-ray burster (GRBs) and several of their other observable properties have been discovered. Four of these properties are considered here: the spectral lag; a measure ... -
More on the nature of the variable star UNSW-V-760
(Oxford University Press, 2012)The results of two multicolour time-series photometric observing runs, separated by about two months, are presented. The same periodicities previously detected in photometry of UNSWV- 760 are still present, albeit at ... -
