Towards A Sounder Fire Ecology, Edward A. Johnson, A Malcolm Gill, Ross Bradstock, Anders Granstrom, Louis Trabaud, Kiyoko Miyanishi Jan 2003

Towards A Sounder Fire Ecology, Edward A. Johnson, A Malcolm Gill, Ross Bradstock, Anders Granstrom, Louis Trabaud, Kiyoko Miyanishi

Faculty of Science, Medicine and Health - Papers: part A

This forum brings together fire ecologists from outside the current wildfire controversy in the US to give their views on three central topics related to ecosystems in which wildfires are an important process. First, how do fire behavior and ecological effects vary between ecosystems? Second, why does this variation require an understanding that goes beyond simple correlations between various fire and ecosystem variables to more careful causal models? Third, how can human values and goals be reconciled with fire disturbance processes in an ecologically sound manner?


Stx1c Is The Most Common Shiga Toxin 1 Subtype Among Shiga Toxin-Producing Escherichia Coli Isolates From Sheep But Not Among Isolates From Cattle, Kim Brett, Vidiya Ramachandran, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven P. Djordjevic Jan 2003

Stx1c Is The Most Common Shiga Toxin 1 Subtype Among Shiga Toxin-Producing Escherichia Coli Isolates From Sheep But Not Among Isolates From Cattle, Kim Brett, Vidiya Ramachandran, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven P. Djordjevic

Faculty of Science, Medicine and Health - Papers: part A

Unlike Shiga toxin 2 (stx2) genes, most nucleotide sequences of Shiga toxin 1 (stx1) genes from Shiga toxin-producing Escherichia coli (STEC), Shigella dysenteriae, and several bacteriophages (H19B, 933J, and H30) are highly conserved. Consequently, there has been little incentive to investigate variants of stx1 among STEC isolates derived from human or animal sources. However stx1OX3, originally identified in an OX3:H8 isolate from a healthy sheep in Germany, differs from other stx1 subtypes by 43 nucleotides, resulting in changes to 12 amino acid residues, and has been renamed stx1c …


Distribution Of Intimin Subtypes Among Escherichia Coli Isolates From Ruminant And Human Sources, Vidiya Ramachandran, Kim Brett, Michael A Hornitzky, Mark Dowton, Karl A Bettelheim, Mark J. Walker, Steven P. Djordjevic Jan 2003

Distribution Of Intimin Subtypes Among Escherichia Coli Isolates From Ruminant And Human Sources, Vidiya Ramachandran, Kim Brett, Michael A Hornitzky, Mark Dowton, Karl A Bettelheim, Mark J. Walker, Steven P. Djordjevic

The intimin gene eae, located within the locus of enterocyte effacement pathogenicity island, distinguishes enteropathogenic Escherichia coli (EPEC) and some Shiga toxin-producing E. coli (STEC) strains from all other pathotypes of diarrheagenic E. coli. EPEC is a leading cause of infantile diarrhea in developing countries, and intimin-positive STEC isolates are typically associated with life-threatening diseases such as hemolytic-uremic syndrome and hemorrhagic colitis. Here we describe the development of a PCR-restriction fragment length polymorphism (RFLP) assay that reliably differentiates all 11 known intimin types (α1, α2, β, γ, κ, ɛ, η, ι, λ, θ, and ζ) and three new …


Evolution Of Sfbi Encoding Streptococcal Fibronectin-Binding Protein I: Horizontal Genetic Transfer And Gene Mosaic Structure, Rebecca J. Towers, Peter K. Fagan, Susanne R. Talay, Bart J. Currie, Kadaba S. Sriprakash, Mark J. Walker, Gursharan S. Chhatwal Jan 2003

Evolution Of Sfbi Encoding Streptococcal Fibronectin-Binding Protein I: Horizontal Genetic Transfer And Gene Mosaic Structure, Rebecca J. Towers, Peter K. Fagan, Susanne R. Talay, Bart J. Currie, Kadaba S. Sriprakash, Mark J. Walker, Gursharan S. Chhatwal

Faculty of Science, Medicine and Health - Papers: part A

Streptococcal fibronectin-binding protein is an important virulence factor involved in colonization and invasion of epithelial cells and tissues by Streptococcus pyogenes. In order to investigate the mechanisms involved in the evolution of sfbI, the sfbI genes from 54 strains were sequenced. Thirty-four distinct alleles were identified. Three principal mechanisms appear to have been involved in the evolution of sfbI. The amino-terminal aromatic amino acid-rich domain is the most variable region and is apparently generated by intergenic recombination of horizontally acquired DNA cassettes, resulting in a genetic mosaic in this region. Two distinct and divergent sequence types that …

Long-term time series of hydrogen chloride (HCl) and chlorine nitrate (ClONO2) total column abundances has been retrieved from high spectral resolution ground-based solar absorption spectra recorded with infrared Fourier transform spectrometers at nine NDSC (Network for the Detection of Stratospheric Change) sites in both Northern and Southern Hemispheres. The data sets span up to 24 years and most extend until the end of 2001. The time series of Cly (defined here as the sum of the HCl and ClONO2 columns) from the three locations with the longest time-span records show rapid increases until the early 1990s …

Psychology And The Enhancement Of Medication Adherence, Mitchell K. Byrne, Frank P. Deane Jan 2003

Psychology And The Enhancement Of Medication Adherence, Mitchell K. Byrne, Frank P. Deane

Faculty of Health and Behavioural Sciences - Papers (Archive)

This paper reports on a new approach to the enhancement of medication adherence - Medication Alliance. Medication Alliance was developed and piloted by a project team that includes Mitch Byrne as project leader, Frank Deane as research supervisor, and two consultants, Tim Coombs and Gordon Lambert. Because Medication Alliance borrows heavily from psychological principles such as functional analysis and cognitive therapy, this presentation is entitled 'Psychology and the Enhancement of Medication Adherence '. However, Medication Alliance is a non-discipline specific therapy approach that fits well within the purview of any clinician delivering psychosocial interventions. The theoretical underpinnings of the various …


Coherent Perspective Jitter Induces Visual Illusions Of Self-Motion, Stephen A. Palmisano, Darren Burke, Robert S Allison Jan 2003

Coherent Perspective Jitter Induces Visual Illusions Of Self-Motion, Stephen A. Palmisano, Darren Burke, Robert S Allison

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research by Palmisano, Gillam and Blackburn (2000) found that adding coherent perspective jitter to constant velocity radial flow improved visually induced illusions of self-motion (known as vection). This was a surprising finding, because unlike pure radial flow, this jittering radial flow should have generated sustained visual-vestibular conflicts - previously thought to always reduce/impair vection. The current experiments attempted to ascertain the essential stimulus features for this jitter advantage for vection by examining three novel types of jitter display. While adding incoherent jitter to radial flow was found to impair vection, adding coherent non-perspective jitter had little effect on this …

Consistency In The Reporting Of Sexual Behavior Among Adolescent Girls In Kenya: A Comparison Of Interviewing Methods, Paul C. Hewett, Barbara Mensch, Annabel Erulkar Jan 2003

Consistency In The Reporting Of Sexual Behavior Among Adolescent Girls In Kenya: A Comparison Of Interviewing Methods, Paul C. Hewett, Barbara Mensch, Annabel Erulkar

Poverty, Gender, and Youth

This paper explores the consistency in reporting of sexual behavior in a household survey of adolescents aged 15-21 in the Kisumu district of Kenya. Respondents were randomly assigned to different interviewing modes: face-to-face interviews, paper-and-pencil self-administered interviews, and audio computer-assisted self-interviewing (ACASI). The analysis focuses on the reporting of sexual behavior by adolescent girls in the face-to-face and ACASI modes and compares responses to a variety of questions about sexual activity, including sexual initiation, risky sexual behavior, and coerced sex. All sexual behavior questions were asked of each adolescent girl even if she answered “no” to the initial question about …


Marriage In Transition: Evidence On Age, Education, And Assets From Six Developing Countries [Arabic], Agnes R. Quisumbing, Kelly Hallman Jan 2003

Marriage In Transition: Evidence On Age, Education, And Assets From Six Developing Countries [Arabic], Agnes R. Quisumbing, Kelly Hallman

Poverty, Gender, and Youth

Marriage is an event of great social and economic significance in most societies. Despite the centrality of marriage in an individual’s life history, the literature on marriage patterns pays little attention to men. This paper examines trends in schooling, age, and assets at marriage for both men and women, and spousal differences in these variables in six countries-Bangladesh, Ethiopia, Guatemala, Mexico, the Philippines, and South Africa-using comparable data sets and methodologies.

Clinical And Forensic Outcomes From The Illinois Mental Health Juvenile Justice Initiative, Michael Jenuwine, John S. Lyons, Gene Griffin, Sharon Quintenz, Michelle Shasha

Articles by Maurer Faculty

To address the mental health needs of youths who are arrested and detained in Illinois, an initiative was designed and implemented that identified youths with psychotic or affective disorders, linked them to community services, and monitored their cases. This study assessed whether such linkage is possible and whether it improves clinical and forensic outcomes. METHODS: Under the initiative, court staff refer youths who may have a mental illness to a clinical liaison. If the youth is eligible for the program, the liaison works with the family to develop a community-based action plan. For the analysis presented here, the Child and …

An Assessment Of Trends In The Use Of The Iud In Ghana, John Gyapong, Gifty Addico, Ivy Osei, Mercy Abbey, Dominic Atweam Kobinah, Henrietta Odoi-Agyarko, Gloria Quansah Asare, Harriet Birungi, Ian Askew

Reproductive Health

Use of the IUD in relation to other contraceptive methods is reported to have either stagnated or declined in a number of countries including Ghana. The overall aim of this study was to inform the Ghana Health Service, USAID, and other partners on future directions for contraceptive promotion and supply. The stagnating demand for the IUD as a family planning method can be attributed to several factors, including perceptions and rumors about the method. The study recommends: intensified marketing of the IUD through the Ghana Life Choices Program; IUD-focused training and creation of a critical mass of trained IUD providers; …


Availability And Acceptability Of Iuds In Guatemala, Carlos Brambila, Berta Taracena Jan 2003

Availability And Acceptability Of Iuds In Guatemala, Carlos Brambila, Berta Taracena

Reproductive Health

The purpose of this study was to identify the reasons for the low use of the IUD in Guatemala and to explore the reasons why other reversible methods are selected more frequently than IUDs. The study aimed to determine the availability and acceptability of IUDs as a contraceptive option within the Ministry of Health, the Guatemalan Social Security Institute, and APROFAM. Results indicated that service providers do not take into consideration women’s reproductive needs or intentions when they provide family planning counseling. There are several demand-side factors that affect the use of the IUD, including lack of knowledge about the …

« Mon Père Pensait Autrement » : Des Garçons Nigérians Réfléchissent À L'Égalité Entre Les Sexes, Françoise Girard

Poverty, Gender, and Youth

L’une des leçons émergeant des programmes pour adolescents dans le monde entier concerne la nécessité de créer des cadres où les jeunes hommes peuvent remettre en question ce qui est souvent considéré comme incontestable, par exemple ce que signifie « être un homme ». Ce numéro décrit le programme nigérian « Conscientiser les adolescents de sexe masculin » (CMA, Conscientizing Male Adolescents). Contrairement à beaucoup de programmes visant les adolescents de sexe masculin, qui mettent l’accent sur des activités à court terme destinées à prévenir la maladie et les grossesses non désirées, le modèle proposé par CMA est un programme …


Female Circumcision In Indonesia. Extent, Implications And Possible Interventions To Uphold Women's Health Rights, Meiwita P. Budiharsana, Lila Amaliah, Budi Utomo Jan 2003

Female Circumcision In Indonesia. Extent, Implications And Possible Interventions To Uphold Women's Health Rights, Meiwita P. Budiharsana, Lila Amaliah, Budi Utomo

Reproductive Health

In Indonesia, the practice of female circumcision (FC) has long existed, but information concerning where and how it is carried out has been limited. The specific aims of the study conducted by the Population Council Jakarta were to provide research-based information on FC customary practices and their socio-cultural determinants, and if possible, to assess any long-term physical and psychological consequences. Study findings indicate that in general Muslim communities support the continuation of FC practice, because they perceive it as both a societal custom and a religious duty. The report strongly recommends that key donor agencies pressure the Ministry of Health …


How Indicators Of Socioeconomic Status Relate To Physical Functioning Of Older Adults In Three Asian Societies, Zachary Zimmer, Napaporn Chayovan, Hui-Sheng Lin, Josefina N. Natividad Jan 2003

How Indicators Of Socioeconomic Status Relate To Physical Functioning Of Older Adults In Three Asian Societies, Zachary Zimmer, Napaporn Chayovan, Hui-Sheng Lin, Josefina N. Natividad

Poverty, Gender, and Youth

In developed countries, socioeconomic status has been identified as one of the most important demographic and social determinants of older adult health. The relationship has not been well studied or contrasted across much of the developing world. Yet, with population aging occurring rapidly in much of Asia, understanding the factors that distinguish between those in better and worse health becomes important. To this end, the current study has two main aims. It first examines the degree to which two measures commonly used to indicate socioeconomic status, education and income, relate to the physical functioning of older adults in three Asian …


The Politics Of Public Health: A Response To Epstein, Lawrence O. Gostin, Maxwell Gregg Bloche Jan 2003

The Politics Of Public Health: A Response To Epstein, Lawrence O. Gostin, Maxwell Gregg Bloche

Georgetown Law Faculty Publications and Other Works

Conservatives are taking aim at the field of public health, targeting its efforts to understand and control environmental and social causes of disease. Richard Epstein and others contend that these efforts in fact undermine people’s health and well-being by eroding people’s incentives to create economic value. Public health, they argue, should stick to its traditional task—the struggle against infectious diseases. Because markets are not up to the task of controlling the transmission of infectious disease, Epstein says, coercive government action is required. But market incentives, not state action, he asserts, represent our best hope for controlling the chronic illnesses that …

Building Effective School-Based Substance Abuse Prevention Programs, Stephanie M. Juhl Jan 2003

Building Effective School-Based Substance Abuse Prevention Programs, Stephanie M. Juhl

Graduate Research Papers

Substance abuse among children and adolescents has become an epidemic in our society. Therefore, it is important to be cognizant of the reasons for child and adolescent substance abuse as well as to recognize risk factors for use. Many prevention programs have not been research-based and are not appropriate for all populations. Several programs and approaches are reviewed as to whether they will reduce the use of substances. School counselors can improve efforts by combining approaches to create comprehensive and multifaceted programs, which will improve the probability of prevention. Creating school counseling programs will be fundamental in preventing early substance …

Poverty, Gender, and Youth

Published by the Population Council's Islamabad office, this is the first comprehensive survey of Pakistani youth. The report provides an unprecedented view of young people's experiences with and attitudes about education, employment, families, and marriage. The report findings confirm the large differences in the current situation of adolescents and youth, males versus females, from different strata of residence and economic status. Addressing these requires government intervention, changes in attitude, and input from the media, women and youth groups, and members of civil society.

Evidence-Based Development Of Health And Family Planning Programs In Bangladesh And Ghana, James F. Phillips, Tanya C. Jones, Frank K. Nyonator, Shruti Ravikumar

Poverty, Gender, and Youth

This paper describes two initiatives that have used experimental studies to guide the development of community-based health and family planning programs. In Bangladesh and Ghana, factorial experiments were implemented in stages. An exploratory phase developed a service system for community-based health care; an experimental phase assessed the demographic impact of the system; a replication phase examined the transferability of the experimental program to a non-research setting; and a scaling-up phase facilitated the extension of the new system to the national health care program. All stages were guided by research, with questions, mechanisms, and outcomes shifting as the process developed. Large-scale …


Completing The Fertility Transition In The Developing World: The Role Of Educational Differences And Fertility Preferences, John Bongaarts Jan 2003

Completing The Fertility Transition In The Developing World: The Role Of Educational Differences And Fertility Preferences, John Bongaarts

Poverty, Gender, and Youth

This study summarizes patterns of educational differentials in wanted and unwanted fertility at different stages of the fertility transition based on data from DHS surveys in 57 less developed countries. As the transition proceeds, educational differentials in wanted fertility tend to decline and differentials in unwanted fertility tend to rise. An assessment of fertility patterns in more and less developed countries with low fertility concludes that these differentials are likely to remain substantial when less developed countries reach the end of their transitions. This finding implies that the educational composition of the population remains a key predictor of overall fertility …

The Living Arrangements Of Older Adults In Sub-Saharan Africa In A Time Of Hiv/Aids, Zachary Zimmer, Julia Dayton

Poverty, Gender, and Youth

The detrimental consequences of the AIDS epidemic for older adults in sub-Saharan Africa suggest the need to investigate their characteristics, living situations, and well-being. In this study, we examine the living arrangements of persons aged 60 and older in 16 countries. Data come from the household roster component of recent Demographic and Health Surveys. The focus is on the tendency of the elderly to live with children and grandchildren, and we examine distributions and determinants. Results show that older adults in sub-Saharan Africa live in a variety of household arrangements. Men are more likely to be living in a nuclear …
