Sustainability Amidst Uncertainty: Columbia Forest Productsâ Pursuit of Sustainability in a Changing Market
Upon reading the latest report from the Department of Housing and Urban Affairs, Harry Demorest found his concerns confirmed â the construction of new homes had fallen yet again across the United States. Over the past month, new home starts had declined over 14% in December; this marked the end of 2007 during which housing starts were down 25% compared to the previous year and hit a low not experienced since 1993. The question was no longer âwill there be a recession?â but rather âhow long will the recession last?â
The fate of Columbia Forest Products, the company that Harry led for 16 years as Chairman and CEO, is tightly bound to the US housing market. CFP has over a 40% market share in hardwood plywood products, most of which go into new home construction. Further, over the past three years, CFP has embarked on a journey into sustainability. This journey is marked most profoundly by the introduction of PureBondÂź non-formaldehyde plywood in 2006. A first in the industry, PureBondÂź provides significant health benefits to CFP employees and customers by removing a known carcinogen from its products. It also has been a catalyst for CFP to pursue a more comprehensive, sustainability-inspired strategy. But in the midst of the dreadful housing market in the US, Harry and the rest of CFP executive team wondered if further pursuit of a sustainability strategy would be detrimental to their companyâs competitiveness

Behavioral and molecular genetics of reading-related AM and FM detection thresholds
Auditory detection thresholds for certain frequencies of both amplitude modulated (AM) and frequency modulated (FM) dynamic auditory stimuli are associated with reading in typically developing and dyslexic readers. We present the first behavioral and molecular genetic characterization of these two auditory traits. Two extant extended family datasets were given reading tasks and psychoacoustic tasks to determine FM 2 Hz and AM 20 Hz sensitivity thresholds. Univariate heritabilities were significant for both AM (h2 = 0.20) and FM (h2 = 0.29). Bayesian posterior probability of linkage (PPL) analysis found loci for AM (12q, PPL = 81 %) and FM (10p, PPL = 32 %; 20q, PPL = 65 %). Bivariate heritability analyses revealed that FM is genetically correlated with reading, while AM was not. Bivariate PPL analysis indicates that FM loci (10p, 20q) are not also associated with reading
Senses, Skills, Reactions and Reflexes: Learning Automatic Behaviors in Multi-Sensory Robotic Systems
Biological systems organization and behavioral strategies allow for the rapid learning of the control of complex tasks. These approaches include the acquisition of skilled behavior through practice and the use of attention. Simulations that emulate these approaches are presented in which the generation of trajectories and the control of motion become automatic during the repeated performance of a task. During this process, shifts in sensory input from vision to proprioception are used for improved task execution and calibration
Maternal Weight Loss during Exclusive Breastfeeding Is Associated with Reduced Weight and Length Gain in Daughters of HIV-Infected Malawian Women
Maternal weight loss during exclusive breastfeeding may influence the growth of exclusively breast-fed infants through impaired quality or quantity of breast milk. This study evaluated how maternal weight loss from 2 to 24 wk postpartum was related to infant weight and length gain in 1309 lactating HIV-infected mothers and their exclusively breast-fed infants. Malawian mother-infant pairs in the Breastfeeding, Antiretrovirals, and Nutrition Study were randomized with a 2 Ă 3 factorial design to a 2-arm nutritional intervention with a lipid-based nutrient supplement (LNS), meeting nutritional needs of lactation, or no LNS and a 3-arm antiretroviral (ARV) intervention (maternal, infant, or no ARV regimen). Linear regression models were used to relate maternal weight loss (weight loss vs. no weight loss) to infant weight and length gain from birth to 24 mo, stratifying by gender and controlling for maternal BMI at 2 wk (mean ± SD: 23.2 ± 3.0 kg/m(2)) and interacting maternal BMI with weight loss. In adjusted models, compared with daughters of women who did not lose weight, length and weight gain were lower in daughters whose mothers had a lower BMI at 2 wk postpartum coupled with the weight loss. For example, among mothers with an initial BMI of 18 kg/m(2), daughters of those who lost weight gained less weight [ÎČ = â0.29 kg (95% CI: â0.53, â0.06)] and length [ÎČ = â0.88 cm (95% CI: â1.52, â0.23)] from birth to 24 wk than daughters of those who gained weight. Though effects were only observed in girls, suggesting possible gender differences in suckling and feeding behavior, these findings indicate that maternal weight loss with low energy reserves represents a risk factor for poor infant growth outcomes
Antiretroviral Treatment Is Associated With Iron Deficiency in HIV-Infected Malawian Women That Is Mitigated With Supplementation, but Is Not Associated With Infant Iron Deficiency During 24 Weeks of Exclusive Breastfeeding
OBJECTIVE: In resource-limited settings without safe alternatives to breastfeeding, the WHO recommends exclusive breastfeeding and antiretroviral (ARV) prophylaxis. Given the high prevalence of anemia among HIV-infected women, mothers and their infants (via fetal iron accretion) may be at risk of iron deficiency. We assessed the effects of maternal micronutrient-fortified lipid-based nutrient supplements (LNS) and maternal ARV treatment or infant ARV prophylaxis on maternal and infant iron status during exclusive breastfeeding from birth to 24 weeks. METHODS: The Breastfeeding, Antiretrovirals, and Nutrition Study was a randomized controlled trial conducted in Lilongwe, Malawi from 2004-2010. HIV-infected mothers (CD4>200 cells/ul) and their infants were randomly assigned to 28-week interventions: maternal-LNS/maternal-ARV (n=424), maternal-LNS/infant-ARV (n=426), maternal-LNS (n=334), maternal-ARV (n=425), infant-ARV (n=426), or control (n=334). Longitudinal models tested intervention effects on hemoglobin (Hb). In a subsample (n=537) with multiple iron indicators, intervention effects on Hb, transferrin receptors (TfR) and ferritin were tested with linear and Poisson regression. RESULTS: In longitudinal models, LNS effects on maternal and infant Hb were minimal. In subsample mothers, maternal ARVs were associated with tissue iron depletion (TfR>8.3 mg/L) (Risk ratio (RR): 3.1, p<0.01), but not in ARV-treated mothers receiving LNS (p=0.17). LNS without ARVs, was not associated with iron deficiency or anemia (p>0.1). In subsample infants, interventions were not associated with impaired iron status (all p-values>0.1). CONCLUSIONS: Maternal ARV treatment with protease inhibitors is associated with maternal tissue iron depletion; but LNS mitigates adverse effects. ARVs do not appear to influence infant iron status; however, extended use needs to be evaluated
