Intersubjective Experience of the Infant and Early Childhood Mental Health Consultant–Program Administrator Consultee Relationship
Authors: DeNatale Laura Mick 
Published: July 2013

ABSTRACTInfant and early childhood mental health consultation has emerged as one of the most common and effective strategies for supporting young children's socioemotional development. A key contributing factor for successful outcomes with this approach is the mental health consultant–consultee relationship. However, there have been no in‐depth qualitative studies to examine the intersubjective nature of the infant and early childhood mental health consultant–program administrator consultee relationship. In this study, 10 infant and early childhood mental health consultants and 15 program administrator consultees who worked together on the Erikson Institute–Illinois State Board of Education Infant and Early Childhood Mental Health Consultation Project were interviewed using qualitative, constructivist, grounded theory methodology. Results suggest that there are multiple internal and external factors that influence the consultant–administrator relationship, resulting in each relationship being a unique, co‐created relationship while sharing similar overall characteristics. Although the relationship can be challenging, especially for consultants during the engagement process, through repeated interactions with each other over an extended period of time, consultants and administrators increasingly experience the relationship to be positive and transformative. Similar to other studies on the early childhood mental health consultant–consultee relationship, it was found that there is a clear relationship between consultants’ and administrators’ perceptions of the relationship.
SCENARIO GENERATION FOR OPERATIONAL RISK
Authors: Mitra Sovan 
Published: July 2013

SUMMARYOperational risk is an increasingly important area of risk management. Scenarios are an important modelling tool in operational risk management as alternative viable methods may not exist. This can be due to challenging modelling, data and implementation issues, and other methods fail to take into account expert information. The use of scenarios has been recommended by regulators; however, scenarios can be unreliable, unrealistic and fail to take into account quantitative data. These problems have also been identified by regulators such as Basel, and presently little literature exists on addressing the problem of generating scenarios for operational risk.In this paper we propose a method for generating operational risk scenarios. We employ the method of cluster analysis to generate scenarios that enable one to combine expert opinion scenarios with quantitative operational risk data. We show that this scenario generation method leads to significantly improved scenarios and significant advantages for operational risk applications. In particular for operational risk modelling, our method leads to resolving the key problem of combining two sources of information without eliminating the information content gained from expert opinions, tractable computational implementation for operational risk modelling, improved stress testing, what‐if analyses and the ability to apply our method to a wide range of quantitative operational risk data (including multivariate distributions). We conduct numerical experiments on our method to demonstrate and validate its performance and compare it against scenarios generated from statistical property matching for comparison.

AbstractWe report the imaging of tendon with Interferometric Second Harmonic Generation microscopy. We observe that the noncentrosymmetric structural organization can be maintained along the fibrillar axis over more than 150 μm, while in the transverse direction it is ∼1–15 μm. Those results are explained by modeling tendon as a heterogeneous distribution of noncentrosymmetric nano‐cylinders (collagen fibrils) oriented along the fibrillar axis. The preservation of the noncentrosymmetric structural organization over multiple tens of microns reveals that tendon is made of domains in which the ratio between fibrils with positive and negative polarity is unbalanced.

Photoinduced partial unfolding of tubulin bound to meso‐tetrakis(sulfonatophenyl) porphyrin leads to inhibition of microtubule formation in vitro
Authors: McMicken Brady , Thomas Robert J. , Brancaleon Lorenzo 
Published: July 2013

AbstractThe irradiation of the complex formed by meso‐tetrakis (sulfonatophenyl) porphyrin (TSPP) and tubulin was investigated as well as its effects on the structure and function of the protein. We have used tubulin as a model target to investigate whether photoactive ligands docked to the protein can affect the structure and function of the protein upon exposure to visible light. We observed that laser irradiation prompts bleaching of the porphyrin which is accompanied by a sharp decrease (∼2 ns) in the average fluorescence lifetime of the protein and a change in the dichroic spectrum consistent with a decrease of helical structure. The result indicated the photoinduced partial unfolding of tubulin. We also observed that such partial conformational change inhibits the formation of microtubules in vitro. We investigated whether photosensitization of reactive oxygen species was responsible for these effects. Even upon removal of O2 the protein still undergoes conformational changes indicating that irradiation of the bound porphyrin does not require the presence of O2 to prompt conformational and functional effects opening the possibility that other mechanisms (e.g., charge transfer) are responsible for the photoinduced mechanism.

Intervals Between Bone Density Testing
Authors: Reid Ian R , Gamble Gregory D 
Published: July 2013

ABSTRACT

There is a wide range of practices regarding times between bone density (BMD) measurements in osteopenic women. If decisions to treat osteoporosis are to be based on absolute fracture risk, then projections of fracture risk are a logical basis for determining appropriate intervals for BMD testing. Fracture risk depends mainly on age and BMD, and bone loss in older women is relatively constant at ∼1% annually, so it is possible to project fracture risk into the future and estimate when an individual's risk will approach the threshold for intervention. Modeling scenarios for a range of osteopenic baseline BMDs in 65-year-old women shows a remarkable consistency in the doubling time for Fracture Risk Assessment Tool (FRAX)-assessed fracture risk: 5 to 6 years. This estimate is of immediate relevance to clinical practice in that it can be used to determine how long to wait before reassessing BMD and fracture risk in women whose other risk factors are stable. © 2014 American Society for Bone and Mineral Research.
Regulation of Cellular Processes by Interleukin‐16 in Homeostasis and Cancer
Authors: Richmond Jillian , Tuzova Marina , Cruikshank William , Center David 
Published: July 2013

AbstractInterleukin‐16 (IL‐16) is generated as a precursor molecule that is cleaved by caspase‐3 to produce a pro‐IL‐16 molecule that functions as a regulator of T cell growth, and a secreted peptide that functions as a CD4 and/or CD9 ligand for induction of cell motility and activation. IL‐16 has been predominantly studied as a contributing factor in the orchestration of an immune response; however, more recently IL‐16 bioactivity has been closely associated with the progression of a number of different cancers. While the association between IL‐16 plasma levels and tumor progression has been reported for many types of cancer, the mechanism for IL‐16 involvement has been partially elucidated for three of the cancer types, cutaneous T cell lymphoma (CTCL), multiple myeloma (MM), and breast cancer. The mechanism for promoting cell growth is different in each of these cancers and involves a sequence mutation in the pro‐molecule facilitating decreased p27KIP1 levels in CTCL; over expression of the secreted IL‐16 molecule to induce proliferation in CTCL T cells, and plasma cells in MM; and increased secreted IL‐16 acting to recruit CD4+ pro‐tumor macrophages in breast cancer. This article will review the cellular process for generating IL‐16, the biological activities for both the pro‐ and secreted forms of the protein, and then the mechanism by which these forms contribute to cancer progression. As a soluble cytokine the ability to reduce or eliminate IL‐16 synthesis through siRNA approaches or bioactivity through the use of neutralizing antibody treatment may represent a novel therapeutic approach.

An active ring fault detected at Tendürek volcano by using InSAR

Published: July 2013

AbstractAlthough ring faults are present at many ancient, deeply eroded volcanoes, they have been detected at only very few modern volcanic centers. At the so far little studied Tendürek volcano in eastern Turkey, we generated an ascending and a descending InSAR time series of its surface displacement field for the period from 2003 to 2010. We detected a large (~105 km2) region that underwent subsidence at the rate of ~1 cm/yr during this period. Source modeling results show that the observed signal fits best to simulations of a near‐horizontal contracting sill located at around 4.5 km below the volcano summit. Intriguingly, the residual displacement velocity field contains a steep gradient that systematically follows a system of arcuate fractures visible on the volcano's midflanks. RapidEye satellite optical images show that this fracture system has deflected Holocene lava flows, thus indicating its presence for at least several millennia. We interpret the arcuate fracture system as the surface expression of an inherited ring fault that has been slowly reactivated during the detected recent subsidence. These results show that volcano ring faults may not only slip rapidly during eruptive or intrusive phases, but also slowly during dormant phases.
Modal Bin Hybrid Model: A surface area consistent, triple‐moment sectional method for use in process‐oriented modeling of atmospheric aerosols
Authors: Kajino Mizuo , Easter Richard C. , Ghan Steven J. 
Published: July 2013

AbstractA triple‐moment sectional (TMS) aerosol dynamics model, Modal Bin Hybrid Model (MBHM), has been developed. In addition to number and mass (volume), surface area is predicted (and preserved), which is important for aerosol processes and properties such as gas‐to‐particle mass transfer, heterogeneous reaction, and light extinction cross section. The performance of MBHM was evaluated against double‐moment sectional (DMS) models with coarse (BIN4) to very fine (BIN256) size resolutions for simulating evolution of particles under simultaneously occurring nucleation, condensation, and coagulation processes (BINx resolution uses x sections to cover the 1 nm to 1 µm size range). Because MBHM gives a physically consistent form of the intrasectional distributions, errors and biases of MBHM at BIN4‐8 resolution were almost equivalent to those of DMS at BIN16–32 resolution for various important variables such as the moments Mk (k: 0, 2, 3), dMk/dt, and the number and volume of particles larger than a certain diameter. Another important feature of MBHM is that only a single bin is adequate to simulate full aerosol dynamics for particles whose size distribution can be approximated by a single lognormal mode. This flexibility is useful for process‐oriented (multicategory and/or mixing state) modeling: Primary aerosols whose size parameters would not differ substantially in time and space can be expressed by a single or a small number of modes, whereas secondary aerosols whose size changes drastically from 1 to several hundred nanometers can be expressed by a number of modes. Added dimensions can be applied to MBHM to represent mixing state or photochemical age for aerosol mixing state studies.
Chemical and mineralogical trends during acid‐sulfate alteration of pyroclastic basalt at Cerro Negro volcano and implications for early Mars

Published: July 2013

AbstractAcid‐sulfate alteration of pyroclastic basalts in active fumaroles at Cerro Negro volcano, Nicaragua, was studied as a means to infer the mineralogical and chemical consequences of basalt alteration in analogous environments on early Mars. At this site, recently erupted basaltic cinders are undergoing alteration by SO2‐bearing steam. During alteration, silicate phenocrysts, including plagioclase, olivine, and augite, react much more rapidly than basaltic glass. Secondary mineralogy is dominated by a very limited number of phases that include amorphous silica, gypsum, Fe‐bearing natroalunite, and Fe‐oxides/oxyhydroxides, including hematite and magnetite. The major element chemistry of the deposits is controlled by two processes: gradual depletion of the major cations other than Si as the basalt components decompose and elements are mobilized out of the deposits, and enrichment in Ca and S from precipitation of gypsum, with Ca apparently supplied from sources below the surface. Reaction path models constrained by these observations but extrapolated to Martian conditions predict that alteration of pyroclastic deposits in similar environments on Mars should produce a secondary mineral assemblage that includes amorphous silica, Fe‐bearing natroalunite, anhydrite, kieserite, and hematite. Iron‐bearing natroalunite was found to produce a Mössbauer signal similar to that of jarosite, suggesting that this phase should be considered as an alternative to the jarosite component identified at Meridiani Planum. Spheroidal hematite formed in close association with natroalunite suggests a pathway for formation of hematite deposits on Mars.

Low‐Temperature Polymerization of ε‐Caprolactone Catalyzed by Cerium Triflates
Authors: Weidner Steffen M. , Scheliga Felix , Kricheldorf Hans R. 
Published: July 2013

Using 22 metal triflates as catalysts, ε‐caprolactone is polymerized at 22 °C in bulk. Only five relatively acidic triflates prove active. Three triflates, including the neutral Sm3+, are active using water as initiator. A very low content of cyclics is found in all the experiments. With Ce3+ and Ce4+, polymerizations are performed in CH2Cl2 and in bulk at 2 °C and 22 °C. Low dispersities (down to 1.1) are obtained. At 22 °C, Ce4+ and, even better, Ce3+ also catalyze syntheses of CO2H‐ and CH2OH‐terminated polycaprolactones, whereby higher dispersities and larger fractions of cyclics are obtained. Further polymerizations and polycondensations are catalyzed with protic acids. The results can be explained by a proton‐catalyzed activated monomer mechanism.

Tailoring Mechanical Properties of Isotactic Polypropylene Via Crystallization of the Mesophase and Control of Stereodefects Concentration
Authors: De Rosa Claudio , Auriemma Finizia , de Ballesteros Odda Ruiz , Di Girolamo Rocco , Tarallo Oreste , Galotto Nella Galotto 
Published: July 2013

AbstractA strategy to tailor the properties of isotactic polypropylene, based on the combination of the crystallization of the mesophase and the control of the molecular structure and concentration of stereodefects via polymerization with metallocene catalysts, is presented. The mechanical properties can be modulated through the conventional slow crystallization from the melt in the α and γ forms, depending on the concentration of stereodefects, or the crystallization of the mesophase by melt quenching. The most stereoirregular sample with rr concentration of 11% shows elastic behavior either when it is slowly crystallized in the γ form or when it is crystallized in the mesomorphic form, but with remarkable differences in the values of the modulus and tensile strength.magnified image
N‐Hydroxyphthalimide‐Mediated Oxidation of Styrene by Molecular Oxygen
Authors: Khan Ezaz Hasan , Pal Sunirmal , De Priyadarsi 
Published: July 2013

In this work, the N‐hydroxyphthalimide (NHPI) is used for the oxidative polymerization of styrene at 25–100 psi oxygen pressure at 35–55 °C to obtain a faster rate of polymerization than in 2,2′‐azobisisobutyronitrile (AIBN)‐initiated polymerizations. The rates for oxidative polymerization are determined from the oxygen consumption (Δp) against time plots and NHPI shows a reaction rate increased several fold compared with AIBN. The kinetics of the oxidative polymerization reactions are studied at various concentrations of oxygen, NHPI, AIBN, and monomer. The polymerization rate of styrene is almost the same when the NHPI analogue, N‐hydroxysuccinimide (NHSI), is employed. A mechanism of oxidative polymerization in the presence of NHPI is suggested on the basis of the kinetic data and characterization results of poly(styrene peroxide) (PSP). The NHPI is efficient in initiation of the oxidative radical polymerization of styrene.

Acridinediones: Effect of Substituents on Their Photoinitiating Abilities in Radical and Cationic Photopolymerization
Authors: Xiao Pu , Dumur Frédéric , Tehfe Mohamad‐Ali , Graff Bernadette , Gigmes Didier , Fouassier Jean Pierre , Lalevée Jacques 
Published: July 2013

Ten acridinediones (ADs) with different substituents are prepared and investigated for their abilities to initiate a ring‐opening cationic photopolymerization in combination with an iodonium salt and N‐vinylcarbazole upon UV–vis light (Xe–Hg lamp; >330 nm) or visible light (halogen lamp) exposure. The structural effects in the ADs are outlined. The cationic and radical photopolymerization of an epoxide/acrylate blend in a one‐step hybrid cure very efficiently leads to the formation of an interpenetrated polymer network under UV–vis light or visible light irradiation (30 s for tack‐free coatings). The photochemical mechanisms are studied by molecular orbital calculations, steady‐state photolysis, electron spin resonance–spin trapping, cyclic voltammetry, fluorescence, and laser flash photolysis techniques.

Propargyl‐Functional Aliphatic Polycarbonate Obtained from Carbon Dioxide and Glycidyl Propargyl Ether
Authors: Hilf Jeannette , Frey Holger 
Published: July 2013

The synthesis of propargyl‐functional poly(carbonate)s with different content of glycidyl propargyl ether (GPE) units is achieved via the copolymerization of propargyl glycidyl ether and carbon dioxide. A new type of functional poly(carbonate) synthesized directly from CO2 and the glycidyl ether is obtained. The resulting polymers show moderate polydispersities in the range of 1.6–2.5 and molecular weights in the range of 7000–10 500 g mol−1. The synthesized copolymers with varying number of alkyne functionalities and benzyl azide are used for the copper‐catalyzed Huisgen‐1,3‐dipolar addition. Moreover, the presence of vicinal alkyne groups opens a general pathway to produce functional aliphatic poly(carbonate)s from a single polymer scaffold.

BackgroundWe have previously described a modified chimeric fibular osteocutaneous flap design based on a combination of a traditional fibular flap and a peroneal artery perforator fasciocutaneous flap for mandible and adjacent soft tissue reconstruction. The purpose of this article is to share our experience with a larger case series utilizing this new technique for mandible and adjacent soft tissue reconstruction after cancer wide excision surgery and a more detailed description on these flaps harvesting procedures.Patients and methodsTen patients (age range from 32 to 63 years), who had segmental defect of mandible and adjacent soft tissue defect after cancer wide excision surgery, received mandible and adjacent soft tissue reconstruction based on the modified chimeric fibular flap design.ResultsThe skin paddle based on peroneal perforators ranged from 9 cm × 3.5 cm to 10 cm × 10 cm and the mean pedicle length was 8.9 cm. Four patients underwent primary closure of the donor site. Three flap salvage procedures were performed due to vascular thrombosis and all flaps survived well. Nine patients had acceptable outer appearance, and one patient complained of cheek sunken. All patients had at least 3‐cm interincisor distance during a mean of 12‐month follow‐up period.ConclusionThe modified chimeric osteocutaneous fibula flaps were feasible design with few intermuscular septum problems during bone fixation. Furthermore, it provided larger skin paddles with few restrictions to reconstruct the cheek skin defect. © 2013 Wiley Periodicals, Inc. Microsurgery 33:439–446, 2013.
Ethylene Propylene Rubber Polyampholytes and their Blends with Polypropylene as an Alternative to Chemically Cross‐Linked Thermoplastic Elastomers and Thermoplastic Vulcanizates
Authors: Powell Andrew , Kontopoulou Marianna , Hojabr Sassan 
Published: July 2013

AbstractAn ethylene propylene rubber polyampholyte (EPR‐g‐PA) containing zwitterionic ammonium carboxylate grafts is prepared by reacting maleated EPR (EPR‐g‐MAn) with a tertiary amino alcohol, 2‐[2‐(dimethylamino)ethoxy]ethanol (DMAEE). EPR‐g‐PA has equivalent viscoelastic properties to an EPR that is lightly cross‐linked using a peroxide cure, but with a higher strain hardening coefficient and elongation at break. EPR‐g‐PA has similar adhesion to metals and improved adhesion to other ionomers, whereas the adhesive strength to a polyamide substrate is reduced compared to the EPR‐g‐MAn. The in situ reaction of EPR‐g‐MAn with DMAEE during blending with PP produced a blend with superior impact properties compared to the thermoplastic vulcanizate (TPV) blend of peroxide cross‐linked EPR‐g‐MAn and PP.
