Purpose: Parents' and children's lives are interwoven over the life course. Parents' positivity and negativity toward children relate to children's and parents' transitions, although the nature of this relationship is unclear. This study investigated the extent to which transitions-like those tied to residence, unions, employment, parenthood, and health-related to parents' positivity and negativity. Method: This study used the Health and Retirement Study's Psychosocial Survey from 2006 and 2010 to examine how parents' and children's transitions related to parents' positivity and negativity toward children...

This study extended previous work investigating two-step liquefaction by supercritical ethanol of rice straw under CO2 atmosphere at temperatures of 270-345 °C. Subcritical CO2 -subcritical ethanol (SubCO2 -SubEtOH) pretreatment decreased the content of lignin in the rice stalk from 22.94 to 21.43 wt%. The results showed that although oxygen-transfer reaction, transesterification, carbonylation, and other reactions may occur with the supercritical CO2 -supercritical ethanol (ScCO2 -ScEtOH) liquefaction reactions, transesterification was the main reaction...

Many high-density cities struggle to find space for disposing municipal solid waste. Hong Kong is one of these cities, seeking to scale up waste recovery efforts as an alternative to disposal. However, territory-wide recovery initiatives do not account for socio-economic variations across place, leading to mixed outcomes among diverse communities. This study aims to investigate socio-economic effects on recycling behavior in a sample of subsidized rental housing estates. It constitutes an improvement from previous studies by using the entire estate as a unit of analysis and analyzing actual recycling outcomes, which have received limited attention from researchers...

Sandy beaches are unique ecosystems increasingly exposed to human-induced pressures. Consistent with emerging frameworks promoting this holistic approach towards beach management, is the need to improve the integration of social data into management practices. This paper aims to increase understanding of links between demographics and community values and preferred beach activities, as key components of the social dimension of the beach environment. A mixed method approach was adopted to elucidate users' opinions on beach preferences and community values through a survey carried out in Manly Local Government Area in Sydney Harbour, Australia...

There is increasing interest in the restoration/regeneration of degraded tropical habitats yet the potential role of natural regenerators remains unclear. We test the hypothesis that the richness and functional diversity of terrestrial mammals differs between forest regrowth stages. We quantified the richness and functional diversity of eight terrestrial mammal seed-disperser species across a forest regrowth gradient in the eastern Brazilian Amazon. We installed camera-traps in 15 sites within small-holder properties with forest regrowth stage classified into three groups, with five sites each of: late second-regrowth forest, early second-regrowth forest and abandoned pasture...

The Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Physical Medicine and Rehabilitation (ABPMR) developed milestones for evaluation of resident physicians that include proper musculoskeletal ultrasound (MSUS) examination of major joints. To date, there have been no published data demonstrating acquisition and retention of these skills and correlation with the milestone evaluation. The investigators developed and implemented a curriculum in musculoskeletal ultrasound examination for Physical Medicine and Rehabilitation (PM&R) residents at a large academic medical center...

Belgium has been collaborating for 20 years with Abomey-Calavi University in Cotonou, Republic of Benin, to train anesthesiologists for Sub-Saharan, French-speaking African countries. With 123 graduates from 15 countries and 46 residents still in training, this program has succeeded in reversing the trend of a decreasing anesthesiology workforce in those countries, thus improving the quality of anesthesia and patient safety. Belgian government sources, as well as hospitals and anesthesia teams, provided most of the financial resources...

Obesity and associated metabolic co-morbidities are a worldwide public health problem. Negative health outcomes associated with obesity, however, do not arise from excessive adiposity alone. Rather, deleterious outcomes of adipose tissue accumulation are a result of how adipocytes are distributed to individual regions in the body. Due to our increased understanding of the dynamic relationship that exists between specific adipose depots and disease risk, an accurate characterization of total body adiposity as well as location is required to properly evaluate a population's disease risk...

INTRODUCTION: Rural family physicians are often required to meet a wide variety of medical service demands that are otherwise the responsibility of specialty physicians in urban centres. However, many rural physicians enjoy the practice variety and ability to meet patients' medical needs through this wider spectrum of care. We aimed to quantify and summarize the workload and clinical disorders seen by rural family physicians in Saskatchewan relative to urban family physicians. METHODS: We used Saskatchewan Ministry of Health billing data for 2015/16 to compare rural and urban care provision...

OBJECTIVE: To examine the potential links between activity spaces, the food retail environment and food shopping behaviours for the population of young, urban adults. DESIGN: Participants took part in the Canada Food Study, which collected information on demographics, food behaviour, diet and health, as well as an additional smartphone study that included a seven-day period of logging GPS (global positioning system) location and food purchases. Using a time-weighted, continuous representation of participant activity spaces generated from GPS trajectory data, the locations of food purchases and a geocoded food retail data set, negative binomial regression models were used to explore what types of food retailers participants were exposed to and where food purchases were made...

The ligand-binding domains (LBD) of the NR5A subfamily of nuclear receptors activate transcription via ligand-dependent and ligand-independent mechanisms. The Drosophila Ftz-F1 receptor (NR5A3) belongs to the latter category and its ligand-independence is attributed to a short helical segment (6) within the protein that resides in the canonical ligand-binding pocket (LBP) in the crystalline state. Here, we show that the 6 helix is dynamic in solution when Ftz-F1 is bound to the LxxLL motif of its cofactor Ftz, undergoing motions on the fast (picosecond-nanosecond) as well as slow (microsecond-millisecond) timescales...

Lungs were considered as sterile for a long time. However, it is now evident that the lungs of healthy people are colonized by microorganisms. Among the bacteria present in the pulmonary microbiota, a significant proportion is anaerobic (strict or facultative). Even though interest in the pulmonary microbiota is increasing, few studies have focused on these unknowns that represent the lung resident anaerobic bacteria. This review describes the biodiversity of anaerobes in physiological conditions, and in different chronic respiratory diseases (cystic fibrosis, COPD, asthma)...

Preoperative identification of the eloquent brain is important for neurosurgical planning. One common method of finding the motor cortex is by localizing "the Omega sign." No studies have tested the reliability of imaging to identify the Omega sign. We identified 40 recent and consecutive patients who had undergone preoperative functional magnetic resonance imaging for identification of the hand motor area prior to tumor resection. We recruited 11 neurosurgical residents of various levels of training and one board-certified neurosurgeon to identify the hand motor cortex Omega...
