ObjectiveTo assess the relationship between parental acculturation and infant feeding style in a sample of Latino parents.MethodsA post hoc analysis was performed using data from an ongoing four‐site randomized controlled trial to promote early childhood obesity prevention. Cross‐sectional data of parent–child dyads at the 12‐month well‐child visit who self‐reported their Latino ethnicity were analyzed. The Short Acculturation Scale for Hispanics (SASH) and a subset of the Infant Feeding Style Questionnaire (IFSQ) that assessed four primary feeding styles were administered. SASH level (low vs. high) with each feeding style was compared by analyses.ResultsComplete SASH data were available for 398 of 431 Latino dyads. Median SASH score was 1.8 (IQR 1.4‐2.7); 82% of participants had low acculturation (score < 3). Of the nine outcome variables, four were significantly associated with SASH: “Laissez‐Faire/attention” (AOR: 2.3; 95% CI: 1.06‐5.13; P = 0.004), “Laissez‐Faire/diet quality” (AOR: 3.9; 95% CI: 1.7‐8.75; P = 0.005), “Pressuring as soothing” (AOR: 3.6; 95% CI:1.63‐8.05; P = 0.007), and “Restrictive/diet quality” (AOR: 0.4; 95% CI: 0.19‐0.94; P = 0.031).ConclusionsLatino parents with lower acculturation were more likely than those with higher acculturation to endorse feeding styles that are associated with child obesity. Further research is needed to determine why acculturation and feeding style relate.

Published: March 2015

AbstractThe traditional structure to function paradigm conceives of a protein's function as emerging from its structure. In recent years, it has been established that unstructured, intrinsically disordered regions (IDRs) in proteins are equally crucial elements for protein function, regulation and homeostasis. In this review, we provide a brief overview of how IDRs can perform similar functions to structured proteins, focusing especially on the formation of protein complexes and assemblies and the mediation of regulated conformational changes. In addition to highlighting instances of such functional equivalence, we explain how differences in the biological and physicochemical properties of IDRs allow them to expand the functional and regulatory repertoire of proteins. We also discuss studies that provide insights into how mutations within functional regions of IDRs can lead to human diseases.
The colonial hydropolitics of infrastructure in the Middle Rio Grande Valley
Authors: Markwell Sam 
Published: March 2015

While the 2010 United Nations Resolution 64/292 on the human right to water and sanitation is an important development, it is not adequate to protecting the range of claims to a human right to water made by rural agricultural communities and Indigenous peoples. To better grasp what is at stake in establishing universal human rights to water, it is important to understand the different infrastructures and institutions through which Indigenous and rural political and ethical communities distribute water. Colonial hydropolitics play a significant role in displacing and obscuring Indigenous alternatives to dominant colonial state concepts of water rights and urban water distribution infrastructures. The Middle Rio Grande Valley provides a site through which we can understand the processes of colonial hydropolitics and the potential of Indigenous alternatives. Research on different histories, geographies, and anthropologies of infrastructures and institutions of water distribution can allow us to better understand the ways colonial hydropolitics have given rise to contemporary problems of water distribution, which in turn can enable a more robust idea of what shapes a universal right to water can take.

Optimization of resonance‐type fatigue testing for a full‐scale wind turbine blade
Authors: Lee Hak Gu , Park Ji‐sang 
Published: March 2015

AbstractFatigue testing of a 48.3 m wind turbine blade needs to utilize the blade's oscillation range of 8.4 m along the flapwise direction for one million cycles. Control of such a remarkable oscillation range makes flapwise fatigue testing difficult and requires a large supply of energy. This study minimized the actuating force required for flapwise fatigue testing using an on‐board‐type resonance exciter with constant amplitude. Constraints related to the exciter's stroke and capacity and the maximum error between target loads and test loads were also considered. Based on a new algorithm suggested in this study, first, we found test setup candidates minimizing the maximum error under a given testing frequency and then found more candidates having slightly larger maximum errors as the exciter's location moved toward the blade's tip. Next, using damping ratio equations for the test blade, a required actuating force of the exciter at each test setup candidate was calculated. Considering the exciter's capacity, we found an optimum test setup that requires a minimum actuating force in the vicinity of the minimum of the maximum error between target loads and test loads. To conclude, the approach suggested in this study was able to conclusively achieve the required fatigue testing of the test blade, avoiding the adverse increase of fatigue testing time possible to happen due to a required actuating force larger than the exciter's capacity.

A review of sustainable energy utility and energy service utility concepts and applications: realizing ecological and social sustainability with a community utility
Authors: Byrne John , Taminiau Job 
Published: March 2015

Strategies that guided development throughout the 20th century relied heavily on economic optimality as a chief guiding principle in the design of energy, technology, markets, and policy. A review of the record of performance of this decision‐making process is followed by a review of proposals to redefine energy progress on sustainability principles. An emerging 21st sustainability paradigm is described which relies on commons‐based economics and long‐term ecological viability. An existing operational expression of the new paradigm—the Sustainable Energy Utility (SEU)—is analyzed as a practical means to arrive at the New Economics and New Policy which might guide the sector. It is compared to the Energy Service Utility and its applications in order to gauge the transformative potential of the SEU.

Cracking the Dumbbell – from (NO)4[Pt2(SO4)5] to (NO)2[Pt(S2O7)3] by Oxidation with SO3
Authors: Bruns Jörn , Niehaus Oliver , Pöttgen Rainer , Wickleder Mathias S. 
Published: March 2015

AbstractThe reaction of elemental platinum, oleum (65 % SO3), and fuming nitric acid in sealed glass ampoules at 350 °C yielded orange single crystals of (NO)4[Pt2(SO4)5] [triclinic, P$\bar{1}$, Z = 4, a = 977.41(3) pm, b = 1318.37(4) pm, c = 1511.47(5) pm, α = 105.218(1)°, β = 95.042(1)°, γ = 102.293(1)°, V = 1814.80(1)·106 pm3]. The crystal structure contains dumbbell shaped [Pt2] moieties surrounded by four chelating sulfate anions, forming the so‐called paddlewheel motif. The paddlewheels are connected via two terminal monodentate sulfate anions to infinite anionic chains. Charge compensation is achieved by nitrosylium cations. The reaction of (NO)4[Pt2(SO4)5] with neat SO3 in sealed glass ampoules at 120 °C yielded yellow single crystals of the tris‐(disulfato)‐platinate(IV) (NO)2[Pt(S2O7)3] [triclinic, P$\bar{1}$, Z = 2, a = 893.20(4) pm, b = 1093.25(4) pm, c = 1098.63(4) pm, α = 62.329(2)°, β = 69.107(2)°, γ = 69.654(2)°, V = 865.88(6)·106 pm3]. In the structure of (NO)2[Pt(S2O7)3] the platinum atoms are coordinated by three bidentate chelating disulfate anions forming an octahedral coordination sphere of oxygen atoms around the platinum atom. Charge compensation is achieved by nitrosylium cations. The thermal behavior of both compounds was monitored by TG/DSC measurements. Magnetic susceptibility measurements on (NO)2[Pt(S2O7)3] revealed diamagnetism, proving the electronic d6 low‐spin configuration of the Pt4+ ion.
Neighborhood and Housing Disorder, Parenting, and Youth Adjustment in Low‐Income Urban Families
Authors: Jocson Rosanne M. , McLoyd Vonnie C. 
Published: March 2015

AbstractUsing two waves of data, this study examined relations among neighborhood and housing disorder, parents’ psychological distress, parenting behaviors, and subsequent youth adjustment in a low‐income, multiethnic sample of families with children aged 6–16. Results supported the hypothesized indirect relation between disorder and youth outcomes via parenting processes. Higher levels of neighborhood and housing disorder were associated with higher levels of parents’ psychological distress, which was in turn related to more frequent use of harsh and inconsistent discipline strategies and lower parental warmth. More frequent use of harsh and inconsistent discipline was associated with higher levels of youth internalizing and externalizing behaviors 3 years later. Housing disorder contributed more strongly to parents’ psychological distress than neighborhood disorder, whereas neighborhood disorder contributed more strongly to youth externalizing behaviors compared to housing disorder. Multiple‐group analyses showed that the patterns of relations were similar for younger and older children, and for girls and boys.

Published: March 2015

AbstractThis study was mainly carried out to detect the quantitative trait loci (QTLs) located simultaneously in embryo and maternal plant nuclear genomes for beneficial fatty acid contents of rapeseed under different environments by using a mapping model and mapping populations from a cross of ‘Tapidor’ × ‘Ningyou7.’ Eight, three, six, seven and three QTLs respectively for palmitic, oleic, linoleic, linolenic and eicosenoic acid contents were identified and subsequently mapped on chromosomes A1, A3, A4, A6, A8, A9, C1, C3, C5, C7, C8 and C9. Among them, 12 QTLs were major ones that could respectively explain more than 10 % of phenotypic variation. Two specific genomic regions on A8 and C3 were associated with several QTLs relating to multiple fatty acid contents. Some of the markers such as HBr015 and JICB0633 showed tight linkage with the QTLs, which could be used for improving the fatty acid component(s) of rapeseed.
An evaluation of a group-based motivational intervention for substance misusers in an Irish forensic setting
Authors: Harper S. , O’Rourke A. 
Published: March 2015

ObjectiveThe purpose of this pilot study was to evaluate a 12-session group-based motivational intervention for substance misusers in a prison setting. The intervention aimed to increase both participants awareness of problem substance use and motivation to change their substance use behaviour.MethodParticipants were recruited for the intervention through active outreach in the prison. Participants of the intervention group completed a structured interview before the group commencing and standardised pre- and post-outcome measures. The results of the intervention group (n=31) were compared with a waiting list control group (n=11).ResultsNon-parametric analysis showed retention rates on this programme at 2, 4 and 6 weeks were 88%, 79% and 76%, respectively. Outcome data were consistent with the predicted direction for the treatment group compared with the wait-list control with significant between-group differences found on ambivalence and taking steps scores.ConclusionThis group-based intervention demonstrated positive levels of client engagement and retention. The intervention was also successful in reducing participant ambivalence about their drug use. Implications for service provision are discussed and design limitations of the present study are considered. Overall, findings indicate the potential utility of a group-based motivational intervention for substance misusers in forensic settings.
Dynamics of sessile drops. Part 2. Experiment
Authors: Chang Chun-Ti , Bostwick J. B. , Daniel Susan , Steen P. H. 
Published: March 2015

High-speed images of driven sessile water drops recorded under frequency scans are analysed for resonance peaks, resonance bands and hysteresis of characteristic modes. Visual mode recognition using back-lit surface distortion enables modes to be associated with frequencies, aided by the identifications in Part 1 (Bostwick & Steen, J. Fluid Mech., vol. 760, 2014, pp. 5–38). Part 1 is a linear stability analysis that predicts how inviscid drop spectra depend on base state geometry. Theoretically, the base states are spherical caps characterized by their ‘flatness’ or fraction of the full sphere. Experimentally, quiescent shapes are controlled by pinning the drop at a circular contact line on the flat substrate and varying the drop volume. The response frequencies of the resonating drop are compared with Part 1 predictions. Agreement with theory is generally good but does deteriorate for flatter drops and higher modes. The measured frequency bands agree better with an extended model, introduced here, that accounts for forcing and weak viscous effects using viscous potential flow. As the flatness varies, regions are predicted where modal frequencies cross and where the spectra crowd. Frequency crossings and spectral crowding favour interaction of modes. Modal interactions of two kinds are documented, called ‘mixing’ and ‘competing’. Mixed modes are two pure modes superposed with little evidence of hysteresis. In contrast, modal competition involves hysteresis whereby one or the other mode disappears depending on the scan direction. Perhaps surprisingly, a linear inviscid irrotational theory provides a useful framework for understanding observations of forced sessile drop oscillations.
Gladius-bearing coleoids from the Upper Cretaceous Lebanese Lagerstätten: diversity, morphology, and phylogenetic implications
Authors: Jattiot Romain , Brayard Arnaud , Fara Emmanuel , Charbonnier Sylvain 
Published: March 2015

AbstractGladius-bearing coleoids are rare in the fossil record. For the Cretaceous period, these cephalopods are mainly recorded in a few Lagerstätten in Lebanon (Haqel, Hajoula, En Nammoura, and Sahel Aalma). Here, we study 16 specimens of gladius-bearing coleoids from these Upper Cretaceous Lebanese Lagerstätten to investigate their taxonomic diversity. Besides two species that were already reported (Dorateuthis syriacaandGlyphiteuthis libanotica), one new species is identified in the Cenomanian site of Hajoula:Rachiteuthis acutalin. sp., as well as another form ofGlyphiteuthisfrom En Nammoura. Several studied specimens exhibit well-preserved soft-part characters. Among them, we document for the first time two transverse rows of sessile suckers inD.syriacaand we confirm the absence of tentacles, as well as the presence of a crop in this species. This strongly supports the phylogenetic proximity ofD.syriacawith modern vampyropods rather than with modern decabrachians. In turn, the similarity in gladius morphology between this taxon and modern squids is regarded as convergent.
Soft-bodied biota from the middle Cambrian (Drumian) Rockslide Formation, Mackenzie Mountains, northwestern Canada
Authors: Kimmig Julien , Pratt Brian R. 
Published: March 2015

AbstractA new Burgess Shale-type Lagerstätte is described from the middle Cambrian (Series 3, Drumian) Rockslide Formation of the Mackenzie Mountains, Northwest Territories, Canada. The Rockslide Formation is a unit of deeper water ramp to slope, mixed carbonate, and siliciclastic facies deposited on the northwestern margin of Laurentia. At the fossil-bearing locality, the unit onlaps a fault scarp cutting lower Cambrian sandstones. There it consists of a succession of shale and thick-laminated to thin-bedded lime mudstone, calcareous sandstone, and greenish-colored calcareous mudstone, overlain by shallower water dolostones of the Avalanche Formation, which is indicative of an overall progradational sequence. The Rockslide Formation is of similar age to the Wheeler and Marjum formations of Utah, belonging to theBolaspidellaBiozone. Only two 1 m thick units of greenish mudstone exhibit soft-bodied preservation, with most specimens coming from the lower interval. However, the biota is common but not as diverse as that of other Lagerstätten such as the Burgess Shale in its type area. The shelly fauna is dominated by the hyolithHaplophrentis carinatusMatthew, 1899 along with sparse linguliformean brachiopods, agnostoid arthropods, and ptychoparioid trilobites. The nonmineralized biota includes the macrophytic algaMargaretia dorusWalcott, 1911, priapulid worms, and the carapaces of a number of arthropods. The arthropods belong toIsoxys mackenziensisn. sp.,Tuzoiacf.T. guntheriRobison and Richards, 1981;Branchiocaris? sp.,Perspicaris?dilatusRobison and Richards, 1981; and bradoriids, along with fragments of arthropods of indeterminate affinities. The style of preservation indicates that most soft parts underwent complete biodegradation, leaving just the more resistant materials such as chitinous arthropod cuticles. The range of preservation and similarity to the coeval biotas preserved in Utah suggests that the composition of this Lagerstätte is probably representative of the community living on the relatively deep-water ramp or slope during middle Cambrian time in Laurentia. This would argue that the extraordinary diversity of the Burgess Shale at Mount Field is anomalous.
Shell ornamentation as a likely exaptation: evidence from predatory drilling on Cenozoic bivalves
Authors: Klompmaker Adiël A. , Kelley Patricia H. 
Published: March 2015

AbstractPredation is an important process in modern oceans and in the evolutionary history of marine ecosystems. Consequently, it has been hypothesized that shelled prey modified their ornamentation in response to predation. However, bivalve ornamentation has also been argued to be important in maintaining a stable life position in the sediment and in burrowing. To test whether concentric ribs were effective against drilling by carnivorous gastropods, we examined drill hole position and completeness for four Cenozoic bivalve species that differ in rib strength (Astarte radiata,A. goldfussi,Lirophora glyptocyma, andL. latilirata). The percentage of drill holes located between the ribs increases with increasing rib strength, whereas the percentage of drill holes on top of ribs decreases. This result suggests that gastropods select the drill hole site more effectively as rib strength increases, thereby saving time and energy, and that natural selection favors gastropods that select drill hole sites between ribs. Because of this greater stereotypy, the percentage of drill holes that are incomplete is generally lower in strongly ribbed species. The proportion of drill holes located on top of ribs is greater for incomplete than complete holes, implying that ribs can be effective against predators, but only when selected as the drilling location. We show that ribs are most effective against drilling predation for bivalves with moderately sized ribs, between which gastropods have difficulty siting drill holes. Concentric ribs are unlikely to have evolved as an adaptation against drilling predation because concentric ribs evolved in the Paleozoic and were already common in the Mesozoic, whereas drilling frequency increased later, in the Late Cretaceous–Paleogene. Moreover, rib strength of North AmericanAstartedid not change through this time interval. Thus, the ribs considered here are a likely exaptation to drilling given their effectiveness at deterring drilling predation on bivalves with moderate ribs.
Cenozoic latitudinal response curves: individualistic changes in the latitudinal distributions of marine bivalves and gastropods
Authors: Zaffos Andrew A. , Miller Arnold I. 
Published: March 2015

AbstractWe use a Gaussian logistic regression model to characterize epoch-to-epoch and stage-tostage changes in the latitudinal response curves of Cenozoic marine bivalve and gastropod genera along the global latitudinal gradient, and analyze these changes to understand the mode and tempo of changes in latitudinal distribution. A ubiquitous ‘‘hollow curve’’ pattern is apparent, wherein smaller changes in response-curve parameters are much more common than larger changes. Curves are strikingly consistent in terms of the average level of change exhibited, despite the many unique environmental and biological changes documented between each of these intervals. This implies that the pace and magnitude of changes in the latitudinal distribution of marine mollusks are not controlled, in aggregate, by time-period-specific conditions. Additionally, we find no evidence for long-term migration from tropical to extratropical latitudes. Our results instead favor a model of either equatorward migration or no general trend. This likely reflects the tendency of genera to maintain their highest concentrations in the tropics even if their ranges become extended out of the tropics over time.

Published: March 2015

Background.Patterns of abnormal neural activation have been observed during working memory tasks in bipolar I depression, yet the neural changes associated with bipolar II depression have yet to be explored.Method.An n-back working memory task was administered during a 3T functional magnetic resonance imaging scan in age- and gender-matched groups of 19 unmedicated, bipolar II depressed subjects and 19 healthy comparison subjects. Whole-brain and region-of-interest analyses were performed to determine regions of differential activation across memory-load conditions (0-, 1- and 2-back).Results.Accuracy for all subjects decreased with higher memory load, but there was no significant group × memory load interaction. Random-effects analyses of memory load indicated that subjects with bipolar II depression exhibited significantly less activation than healthy subjects in left hemispheric regions of the middle frontal gyrus [Brodmann area (BA) 11], superior frontal gyrus (BA 10), inferior parietal lobule (BA 40), middle temporal gyrus (BA 39) and bilateral occipital regions. There was no evidence of differential activation related to increasing memory load in the dorsolateral prefrontal or anterior cingulate cortex.Conclusions.Bipolar II depression is associated with hypoactivation of the left medio-frontal and parietal cortex during working memory performance. Our findings suggest that bipolar II depression is associated with disruption of the fronto-parietal circuit that is engaged in working memory tasks, which is a finding reported across bipolar subtypes and mood states.
