By drawing upon birth history data gleaned from the 2007 and 2010 rounds of the National Survey on Work and Family (NSWF), we estimate the relationship between the married female worker's use of the childcare leave scheme and her hourly wage, and then evaluate the impact of her predicted hourly wage upon her probability of proceeding from parity 0 to parity 1, as well as from parity 1 to parity 2. We find that married Japanese women working full-time, who took advantage of childcare leave, earned considerably higher hourly wages than their part-time counterparts. However, the higher predicted hourly wage lowered the probability of having first two children.

Recent concerns with pandemic outbreaks of human disease and their origins in animal populations have ignited concerns regarding connections between Emerging Infectious Diseases (EID) and development. As disasters, health, and infectious disease become part of planning concern (Matthew & McDonald, 2007), greater focus on household infrastructure and EID disease outbreaks among poultry is warranted. Following Spencer (2013), this study examines the relationship between the mix of household-scale water supplies, sanitation systems, and construction materials, and Highly Pathogenic Avian Influenza (HPAI) among poultry in a developing country: Vietnam.

Article Synopsis
  • Phytophthora palmivora is a plant pathogen linked to significant crop damage, particularly in papaya, yet the mechanisms behind its infection are not fully understood.
  • Researchers identified a secreted glycoprotein called Ppal15kDa which, when manipulated in genetic experiments, significantly influenced the pathogen's ability to infect host plants.
  • The study suggests that Ppal15kDa is crucial for both the development of infection structures and overall pathogenicity in P. palmivora, highlighting its potential role in similar pathogens.

Article Synopsis
  • - The Alpha Magnetic Spectrometer (AMS) conducted precision measurements of helium isotopes (^3He and ^4He) on the International Space Station, collecting data from 100 million ^4He and 18 million ^3He nuclei over six years from 2011 to 2017.
  • - The study found that the fluxes of both helium isotopes varied similarly over time, but the amount of variation decreased as the rigidity (energy per unit charge) increased.
  • - For the first time, researchers measured the rigidity dependence of the ^3He/^4He flux ratio, showing notable long-term changes below 4 GV but stable characteristics and a specific power law relationship above that threshold, aligning with other spectral indices in

Purpose Of Review: To explore the comparative importance of HIV infections among key populations and their intimate partners as HIV epidemics evolve, and to review implications for guiding responses.

Recent Findings: Even as concentrated epidemics evolve, new infections among current and former key population members and their intimate partners dominate new infections. Prevalent infections in the general population grow primarily because of key population turnover and infections among their intimate partners.

Towards Understanding the Origin of Cosmic-Ray Positrons.

Phys Rev Lett

February 2019

INFN TIFPA, I-38123 Povo, Trento, Italy.

Article Synopsis
  • Precision measurements of cosmic ray positrons up to 1 TeV were gathered by the Alpha Magnetic Spectrometer aboard the International Space Station, analyzing 1.9 million positrons.
  • A significant excess of positrons begins at around 25.2 GeV, followed by a sharp decrease above approximately 284 GeV, indicating a complex energy dependency.
  • The data suggests that at high energies, positrons mainly come from either dark matter annihilation or other astrophysical sources, with a notable energy cutoff of the source term established at about 810 GeV.

Climate change is expected to alter precipitation patterns worldwide, which will affect streamflow in riverine ecosystems. It is vital to understand the impacts of projected flow variations, especially in tropical regions where the effects of climate change are expected to be one of the earliest to emerge. Space-for-time substitutions have been successful at predicting effects of climate change in terrestrial systems by using a spatial gradient to mimic the projected temporal change.

Urbanization has been driven by various social, economic, and political factors around the world for centuries. Because urbanization continues unabated in many places, it is crucial to understand patterns of urbanization and their potential ecological and environmental impacts. Given this need, the objectives of our study were to quantify urban growth rates, growth modes, and resultant changes in the landscape pattern of urbanization in Hanoi, Vietnam from 1993 to 2010 and to evaluate the extent to which the process of urban growth in Hanoi conformed to the diffusion-coalescence theory.

Introduction: Thailand has been heralded as a global leader in HIV prevention and treatment, and its experience with the HIV/AIDS epidemic holds valuable lessons for public health. This paper documents Thailand's response to its HIV epidemic from the late 1980s until today, and analyses its epidemiological impact (incidence and mortality). We discuss the association between the trajectory of HIV incidence and mortality rates over time, and the programmatic investments, policies and interventions that were implemented in the last three decades.

Highly pathogenic avian influenza (HPAI) is an important public health concern because of potential for widespread morbidity and mortality in humans and poultry and associated devastating economic losses. We examined how perceptions of the risk of HPAI in poultry vary across communes/wards in the north of Vietnam at different levels of urbanization (rural, peri-urban, urban). Analyses of questionnaire responses from 1081 poultry raisers suggested that the perceived risk of HPAI in poultry was highest in peri-urban and rural settings.

Article Synopsis
  • Knowledge of the boron to carbon (B/C) flux ratio is crucial for understanding cosmic ray propagation.
  • A precise measurement of this ratio was made from 1.9 GV to 2.6 TV using data from 2.3 million boron and 8.3 million carbon nuclei collected by AMS over 5 years.
  • The findings indicate that the B/C ratio does not demonstrate significant structures at high rigidities, and above 65 GV, it follows a single power law closely aligning with Kolmogorov's turbulence theory.

Insights in Public Health: All About the Insurance: The US health-Care System Through a Foreigner's Eyes.

Hawaii J Med Public Health

September 2016

Office of Public Health Studies at the University of Hawai'i at Manoa, Honolulu, HI. (Ruth Pitt is a second year Masters in Public Health student from Australia. She took the United States Health Care Systems Course in Summer 2015, as part of a Graduate Degree Fellowship at the East-West Center.).

Hawai'i had high insurance coverage rates even before the Affordable Health Care Act and continues to have a high percentage of the population with health insurance today. However, high insurance rates can disguise wide variation in what is covered and what it costs. In this essay, an Australian Masters in Public Health student from the University of Hawai'i considers the strengths and weaknesses of insurance coverage in the US health-care system when her friend "Peter" becomes seriously ill.
