SUMMARYForage sorghum (FS) (Sorghum bicolor(L.) Moench) is a key feed source for ruminants owing to its high yield and drought tolerance. The present paper assessed the agronomic characteristics, silage quality, intake and digestibility of five new Brazilian sorghum cultivars (BRS Ponta Negra variety, BRS 655 hybrid, BR 601 hybrid, BRS 506 variety and BRS 610 hybrid). Forages were grown (randomized complete block design) in a typical Brazilian north-eastern semi-arid climate, irrigated with 267 mm water, harvested as plants reached the soft dough stage of grain maturity and ensiled under laboratory and farm conditions. Apparent digestibility of the silages was determined using 25 Santa Inês lambs. BRS 506 outperformed the other cultivars in dry matter (DM) and digestible DM yields/ha. BRS 506 exhibited the lowest neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents and the highestin vitrodry matter digestibility (IVDMD) of the cultivars examined. BRS 655 produced the lowest level of lactic acid and the highest pH and ammonia-N concentration. There was no difference in intake or digestibility of DM among cultivars. Silages produced from BRS Ponta Negra resulted in higher crude protein (CP) intake than BRS 655. Silages made from BRS 506 and BRS Ponta Negra resulted in a greater digestibility of CP than those produced from BRS 655. Intake of NDF in silages generated from BRS Ponta Negra and BRS 610 was higher than that found in other cultivars. Although an average Brazilian North-eastern FS exhibited similar characteristics to other cultivars grown in dry regions around the world, the results indicated that BRS 506 had a yield advantage and higher nutritive value under Brazilian semi-arid conditions as compared to the other cultivars examined.

SUMMARYTo upgrade the use of permanent grasslands in livestock farming systems for their economic and environmental utility, their value needs better assessment in terms of both quantity (biomass production) and quality (nutritive value: organic matter digestibility (OMD) and crude protein content (CP)). The wide variability in permanent grassland botanical composition makes it important to understand the links between vegetation characteristics and permanent grassland value, and how far environmental factors influence this value. The current work investigated how vegetation characteristics and weather explained the variability of the biomass production and nutritive value of permanent grasslands. Two models were used to determine the best vegetation characteristics for the prediction: (i) plant functional types (PFT), proportions of grasses, legumes and forbs and weather, and (ii) two proxies for PFT (dry matter content (DMC) and phenological development at medium plant stage (MPS)), proportion of grasses, legumes and forbs, and weather. The study was conducted on a set of 190 permanent grasslands distributed over a wide range of soil, climatic and management conditions, and lasted 2 years (2009/10). For each of the permanent grasslands, climatic data, values of vegetation characteristics, biomass production and nutritive value were collected at the beginning and end of spring, and during summer and autumn regrowths. Contribution of weather was important and particularly for regrowths. Composition in terms of botanical families, plant stage and sward DMC was the common variables that explained both biomass production and nutritive value during the growing season. Biomass production was mainly explained by the proportion of legumes and forbs, MPS and DMC considering both models. Grass nutritive value was linked to the same factors, including PFT. However, the contribution of grass PFTs was lower in models. Both models could be used to predict biomass production and nutritive value:R2of the two models are quite similar. Over a wide range of environmental and management conditions, vegetation characteristics and climatic data explained almost half of the variance of forage quality and 20–40% of the variance of biomass production.

Published: July 2014

The effects of use of adjunct cultures (Lactobacillus helveticusandLb. casei) and ripening temperatures (6 or 12 °C) on proteolysis and angiotensin-I converting enzyme (ACE)-inhibitory activity in white-brined cheeses were investigated during 120 d ripening. Proteolysis was monitored by urea-polyacrylamide gel electrophoresis (urea-PAGE) and reversed phase-HPLC (RP-HPLC) of water-insoluble and -soluble fractions of the cheeses, respectively. Urea-PAGE patterns of the samples revealed that the intensities of the bands representing casein fractions decreased in the experimental cheeses, being more pronounced in the cheeses made with adjunct cultures. Similarly, peptide profiles and the concentrations of individual and total free amino acids were influenced by both the adjunct cultures and ripening temperatures. The ACE-inhibitory activity of the water-soluble extracts of the cheeses were higher in the cheeses made using adjunct cultures (especiallyLb. helveticus) and ripened at 12 °C. The ACE-inhibitory activity did not decrease during ripening. The contribution ofLb. helveticusto the development of proteolysis and ACE-inhibitory peptide activities were higher than that ofLb. casei. To conclude, the use ofLb. helveticusas adjunct culture in white-brined cheese and ripening at 12 °C would be recommended to obtain white-brined cheese with high ACE-I-inhibitory peptides activity and higher levels of preoteolysis.
Bringing clarity to the clouded leopard Neofelis diardi: first density estimates from Sumatra
Authors: Sollmann Rahel , Linkie Matthew , Haidir Iding A. , Macdonald David W. 
Published: July 2014

AbstractWe use data from camera-trap surveys for tigers Panthera tigris in combination with spatial capture–recapture models to provide the first density estimates for the Sunda clouded leopard Neofelis diardi on Sumatra. Surveys took place during 2004–2007 in the Kerinci landscape. Densities were 0.385–1.278 per 100 km2. We found no statistically significant differences in density among four study sites or between primary and mixed forest. Because the data sets are too small to account for differences in detection parameters between sexes, density is probably underestimated. Estimates are comparable to previous estimates of 1–2 per 100 km2 from the lowlands of central Sabah, on Borneo. Data limitations suggest that camera-trap surveys for Sunda clouded leopards require traps spaced more closely, to increase the chance of recaptures at different traps. Nevertheless, these first density estimates for clouded leopards on Sumatra provide a benchmark for measuring future conservation impact on an island that is undergoing rapid forest loss.
Nature, mystery, and morality: a Daoist view
Authors: KIDD IAN JAMES 
Published: July 2014

AbstractThis article argues that a sense of nature's mystery can inspire and inform ways of experiencing and engaging with natural places and creatures in a way that is deeply morally transformative. Focusing on Daoism, it argues that engagement with natural places and creatures can facilitate the cultivation of receptivity to a sense of nature's mystery in a way that gradually releases a person from stances and conceptions that are morally and ecologically objectionable. The article closes by suggesting that a capacity to cultivate receptivity to nature's mystery is contingent upon the concerns and convictions of our background moral and social culture.
The on-line processing of binding principles in second language acquisition: Evidence from eye tracking
Authors: KIM EUNAH , MONTRUL SILVINA , YOON JAMES 
Published: July 2014

ABSTRACTThis study examined how adult L2 learners make use of grammatical and extragrammatical information to interpret reflexives and pronouns. Forty adult English native speakers and 32 intermediate–advanced Korean L2 learners participated in a visual world paradigm eye-tracking experiment. We investigated the interpretation of reflexives (himself) and pronouns (him) in contexts where there is a potential coargument antecedent and in the context of picture noun phrases (a picture of him/himself), where the distribution of reflexives and pronouns can overlap. The results indicated that the learners interpreted reflexives in a nativelike fashion in both contexts, whereas they interpreted pronouns differently from native speakers, even when learners had advanced English proficiency. Adopting the binding theory as developed in the reflexivity/primitives of binding framework (Reinhart & Reuland, 1993; Reuland, 2001, 2011), we interpret these results to mean that while adult L2 learners are able to apply syntactic binding principles to assign an interpretation to anaphoric expressions, they have difficulty in integrating syntactic information with contextual and discourse information.

Abstract:Rigorous population studies on many small carnivores are lacking in India. Presence-absence models with habitat covariates were applied to estimate seasonal occupancy and abundance of nine small-carnivore species from camera-trap data in Mudumalai Tiger Reserve (2010 and 2011). We deployed 25 camera-trap stations in the deciduous forest, 21 in the semi-evergreen forest and 26 in the dry thorn forest. In total, 7380 trap-nights yielded 448 photographs of small carnivores: jungle cat (n = 72), leopard cat (n = 6), rusty-spotted cat (n = 11), small Indian civet (n = 89), common palm civet (n = 37), brown palm civet (n = 20), stripe-necked mongoose (n = 66), ruddy mongoose (n = 96) and Indian grey mongoose (n = 51). In the dry season, rusty-spotted cat was the rarest carnivore with an average abundance (λmean) of 0.24 ± 0.26, while ruddy mongoose was the most abundant (λmean = 0.90 ± 0.40). In the wet season, leopard cat was the rarest species (λmean = 0.048 ± 0.041) while grey mongoose was the most abundant (λmean = 0.68 ± 0.35). Abundance of jungle cat, common palm civet, ruddy mongoose and grey mongoose increased in the dry thorn forest whereas in the dry season abundance of small Indian civet decreased in this forest type. Abundance of leopard cat and small Indian civet was not influenced by habitat in the wet season. Deciduous forest was positively associated with abundance of rusty-spotted cat. Deciduous and semi-evergreen forests had a positive effect on abundance of stripe-necked mongoose while the latter was a positive predictor of abundance and occupancy for brown palm civet. Improved modelling approaches can account for the spatio-temporal variation in habitat use of small carnivores occupying specialized niches in heterogeneous tropical forests of southern India.

SUMMARYTwo clusters of confirmed cryptosporidiosis infections were detected in Navarra, Spain, in the summer of 2012, in the context of an increased incidence in the region. Molecular subtyping ofCryptosporidium hominisdetermined that one cluster, occurring in an urban area, was due to the predominant circulating subtype IbA10G2R2 and the other cluster, with cases occurring in a rural area, was due to a rare subtype IaA18R3. No single exposure was associated with infection, although exposure to certain children's pools was reported by a majority of patients interviewed in each cluster. Genotyping tools were useful in the investigation and could aid investigation of cryptosporidiosis outbreaks in Spain in the future.
Small for gestational age and poor fluid intelligence in childhood predict externalizing behaviors among young adults born at extremely low birth weight

Published: July 2014

AbstractAlthough infants born at extremely low birth weight (ELBW; birth weight < 1000 g) are at increased risk for developing later psychopathology, the mechanisms contributing to this association are largely unknown. In the present study, we examined a putative cognitive link to psychopathology in a cohort of ELBW survivors. These individuals were followed up prospectively at age 8 and again at ages 22–26. At 8 years, participants completed measures of fluid and general intelligence. As young adults, a subset of ELBW survivors free of major neurosensory impairments provided self-reports of personality characteristics related to psychopathology. Data from 66 participants indicated that, as predicted, the association between ELBW and externalizing behaviors was moderated by fluid intelligence. Specifically, ELBW individuals with poor fluid intelligence who were born small for gestational age (birth weight < 10th percentile for gestational age) showed the highest level of externalizing behaviors. These findings provide support for a cumulative risk model and suggest that fluid intelligence might be a cognitive mechanism contributing to the development of psychopathology among nonimpaired individuals who were born at ELBW and small for gestational age.
Working Memory Mediates the Relationship between Intellectual Enrichment and Long-Term Memory in Multiple Sclerosis: An Exploratory Analysis of Cognitive Reserve
Authors: Sandry Joshua , Sumowski James F. 
Published: July 2014

AbstractSome individuals with multiple sclerosis (MS) show decrements in long-term memory (LTM) while other individuals do not. The theory of cognitive reserve suggests that individuals with greater pre-morbid intellectual enrichment are protected from disease-related cognitive decline. How intellectual enrichment affords this benefit remains poorly understood. The present study tested an exploratory meditational hypothesis whereby working memory (WM) capacity may mediate the relationship between intellectual enrichment and verbal LTM decline in MS. Intellectual enrichment, verbal LTM, and WM capacity were estimated with the Wechsler Test of Adult Reading and Peabody Picture Vocabulary Test, delayed recall of the Hopkins Verbal Learning Test-Revised and Logical Memory of the Wechsler Memory Scale, and Digit Span Total, respectively. Intellectual enrichment predicted LTM (B=.54;p=.003) and predicted WM capacity (B=.91;p<.001). WM capacity predicted LTM, (B=.44;p<.001) and fully mediated the relationship between intellectual enrichment (B=.24;p=.27) and LTM (B=.33,p=.03), Sobel test,Z=3.31,p<.001. These findings implicate WM capacity as an underlying mechanism of cognitive reserve and are an initial first step in understanding the relationship between intellectual enrichment, WM, and LTM in MS.

How much do respondents in the health and retirement study know about their contributions to tax-deferred contribution plans? A cross-cohort comparison
Authors: DUSHI IRENA , HONIG MARJORIE 
Published: July 2014

AbstractWe use information from Social Security earnings records to examine the accuracy of survey responses regarding participation in tax-deferred pension plans. As employer-provided defined benefit pensions are replaced by voluntary contribution plans, employees’ understanding of the link between their annual contributions and their post-retirement wealth is becoming increasingly important. We examine the extent to which wage-earners in the Health and Retirement Study (HRS) correctly report their inclusion in tax-deferred contribution plans and, conditional on inclusion, their annual contributions. We use three samples representing different cohorts in three different periods: the original HRS cohort interviewed in 1992 at ages 51–56, the War Babies cohort interviewed in 1998 at ages 51–56, and the Early Baby Boomer cohort interviewed in 2004 at the same ages. Our findings indicate that while respondents interviewed in 1998 and 2004 were more likely to correctly report whether they were included in defined contribution plans, they were no more accurate when reporting whether they had contributed to their plans than respondents interviewed in 1992. Contributors in the three cohorts, moreover, overstated their annual contributions and thus would be likely to realize lower than expected account balances at retirement. The magnitude of this error is not negligible. In all three cohorts, the mean reporting error (the absolute difference between respondent-reported and Social Security earnings record contributions) was approximately 1.5 times larger than the mean contribution in the W-2 earnings record.

Published: July 2014

Purpose:To evaluate planning quality of SBRT with multiple lung metastases generated with Pinnacle and TomotherapyMethods:Nine randomly selected patients diagnosed with non small‐cell lung cancer with multiple lesions were planned with Pinnacle (version 9.2) and Tomotherapy (version 4.2). Coplanar and non_coplanar plans were generated on Pinnacle. A total dose of 60 Gy was prescribed to 95% of PTV in 3 fractions. Single isocenter was used. Nine static beams were used for Pinnacle plans. Planning outcomes such as minimum and mean dose, V9 5, D9 5 (95% of target volume receives prescription dose), D5, and D1 to PTV, maximum dose to heart, esophagus, cord, trachea, brachial plexus, rib, chest wall, and liver, mean dose to liver, total lung, right and left lung, volume of chest wall receives 30 Gy, volume of lungs receives 5 Gy and 20Gy, conformity index (CI = PIV / PTV) and heterogeneity index (HI = D5 / D9 5) were reported for evaluation.Results:The mean volume of PTV was 37.77 ± 23.4 cm3. D9 5 of PTV with Tomo, coplanar, non_coplanar was 60.2 ± 0.3 Gy, 58.6 ± 1.2 Gy, and 59.1 ± 0.7 Gy, respectively. Mean dose to PTV was lower for Tomo (p < 0.0001), so were D5 (p < 0.0001) and D1 (p = 0.001). CI was better with Tomo (p < 0.0001), so was HI (p < 0.0001). Maximum dose to other critical organs were also lower exclusively with Tomo plans. Treatment time was recorded only for Tomo plans (73.0 ± 20.6 min).Conclusion:With 51 beam angles, Tomo plans could generally achieve better tumor coverage while sparing more critical structures for multiple lung lesions study. Non_coplanar also has better tumor coverage with lower dose to critical organs such as lungs, liver, chest wall and cord compare to coplanar plans.
SU‐E‐T‐335: Transit Dosimetry for Verification of Dose Delivery Using Electronic Portal Imaging Device (EPID)
Authors: Baek T , Chung E , Lee S , Yoon M 
Published: July 2014

Purpose:To evaluate the effectiveness of transit dose, measured with an electronic portal imaging device (EPID), in verifying actual dose delivery to patientsMethods:Plans of 5 patients with lung cancer, who received IMRT treatment, were examined using homogeneous solid water phantom and inhomogeneous anthropomorphic phantom. To simulate error in patient positioning, the anthropomorphic phantom was displaced from 5 mm to 10 mm in the inferior to superior (IS), superior to inferior (SI), left to right (LR), and right to left (RL) directions. The transit dose distribution was measured with EPID and was compared to the planed dose using gamma index.Results:Although the average passing rate based on gamma index (GI) with a 3% dose and a 3 mm distance‐to‐dose agreement tolerance limit was 94.34 % for the transit dose with homogeneous phantom, it was reduced to 84.63 % for the transit dose with inhomogeneous anthropomorphic phantom. The Result also shows that the setup error of 5mm (10mm) in IS, SI, LR and SI direction can Result in the decrease in values of GI passing rates by 1.3% (3.0%), 2.2% (4.3%), 5.9% (10.9%), and 8.9% (16.3%), respectively.Conclusion:Our feasibility study suggests that the transit dose‐based quality assurance may provide information regarding accuracy of dose delivery as well as patient positioning.
SU‐E‐T‐347: Validation of the Condensed History Algorithm of Geant4 Using the Fano Test
Authors: Lee H , Mathis M , Sawakuchi G 
Published: July 2014

Purpose:To validate the condensed history algorithm and physics of the Geant4 Monte Carlo toolkit for simulations of ionization chambers (ICs). This study is the first step to validate Geant4 for calculations of photon beam quality correction factors under the presence of a strong magnetic field for magnetic resonance guided linac system applications.Methods:The electron transport and boundary crossing algorithms of Geant4 version 9.6.p02 were tested under Fano conditions using the Geant4 example/application FanoCavity. User‐defined parameters of the condensed history and multiple scattering algorithms were investigated under Fano test conditions for three scattering models (physics lists): G4UrbanMscModel95 (PhysListEmStandard_option3), G4GoudsmitSaundersonMsc (PhysListEmStandard_GS), and G4WentzelVIModel/G4CoulombScattering (PhysListEmStandard_WVI). Simulations were conducted using monoenergetic photon beams, ranging from 0.5 to 7 MeV and emphasizing energies from 0.8 to 3 MeV.Results:The GS and WVI physics lists provided consistent Fano test results (within ±0.5%) for maximum step sizes under 0.01 mm at 1.25 MeV, with improved performance at 3 MeV (within ±0.25%). The option3 physics list provided consistent Fano test results (within ±0.5%) for maximum step sizes above 1 mm. Optimal parameters for the option3 physics list were 10 km maximum step size with default values for other user‐defined parameters: 0.2 dRoverRange, 0.01 mm final range, 0.04 range factor, 2.5 geometrical factor, and 1 skin. Simulations using the option3 physics list were ∼70 – 100 times faster compared to GS and WVI under optimal parameters.Conclusion:This work indicated that the option3 physics list passes the Fano test within ±0.5% when using a maximum step size of 10 km for energies suitable for IC calculations in a 6 MV spectrum without extensive computational times. Optimal user‐defined parameters using the option3 physics list will be used in future IC simulations to calculate beam quality correction factors under the presence of a magnetic field.Elekta‐MD Anderson Research Agreement
