Annual Change in Ohio Hardwood Stumpage Prices, 1960 to 2011
Authors: Duval Raymond P , McConnell T. Eric , Hix David M 
Published: December 2013

Abstract
Timber price trends provide economic information for forest management and wood utilization decision making, yet to our knowledge, no comprehensive examination of Ohio timber price data has been conducted. Stumpage prices reported biannually from 1960 to 2011 (dollars per thousand board feet, Doyle) for the 10 commercial hardwood species of Ohio were obtained from the Ohio Timber Price Report. Average annual percentage rates of change were determined using log-linear modeling, which included testing and accounting for serial correlation of the residuals. The real price data of each species (1982 dollars) were further examined for differing trend lines between the periods 1960 to 1985 and 1986 to 2011. Nominal prices have been increasing annually between 3.57 percent for basswood (Tilia americana) and 6.13 percent for cherry (Prunus serotina). Real price rates of change were lowest for basswood, −0.25 percent, and highest for cherry, 2.19 percent. The species separated into three groups based on trend line intercept (initial price) and/or slope (rate of price change) differences between the two eras. No differences were observed between eras for cherry, hard and soft maple (Acer spp), hickory (Carya spp.), walnut (Juglans nigra), and yellow-poplar (Liriodendron tulipifera). Basswood prices in the second era were changing at a significantly lower rate than in the first era. Distinct trend lines were found between eras for ash (Fraxinus spp.), and red and white oak (Quercus spp.). Initial prices for the three were significantly higher in the second era, while rates of price change were significantly lower in the second era.

Abstract
G-protein coupled receptor 119 (GPR119) is emerging as a potential target for the treatment of type 2 diabetes with beneficial effects on glucose homeostasis. This study assessed the insulin-secreting properties of various GPR119 agonists and the distribution of GPR119 in pancreatic islets. Endogenous ligands [oleoylethanolamide (OEA), palmitoylethanolamine (PEA)] and chemically synthetic analogues (AS-1269574, PSN-375963) were investigated in clonal BRIN-BD11 cells and mouse pancreatic islets. Secondary messenger assays such as intracellular Ca2+ and cAMP in response to agonists at normoglycaemic and hyperglycaemic conditions were assessed. Cytotoxicity was assessed by LDH release. AS-1269574 was the most potent and selective agonist tested in isolated islets, with an EC50 value of 9.7×10-7 mol/l, enhancing insulin release maximally by 63.2%. Stimulation was also observed with GPR119 ligands; OEA (3.0×10-6 mol/l; 37.5%), PSN-375963 (2.4×10-6 mol/l; 28.7%) and PEA (1.2×10-6 mol/l; 22.2%). Results were corroborated by studies using BRIN-BD11 cells, which revealed augmentation of intracellular Ca2+ and cAMP. Both OEA and AS-1269574 enhanced insulin release and improved glucose tolerance in vivo in NIH Swiss mice. These results demonstrate the cellular localisation of GPR119 on islet cells (β and pancreatic polypeptide cells), its activation of the β-cell stimulus-secretion coupling pathway and glucose lowering effects in vivo.
Numerical inversion of the spherical Radon transform and the cosine transform using the approximate inverse with a special class of locally supported mollifiers
Authors: Riplinger Martin , Spiess Malte 
Published: December 2013

Abstract
The focus of this paper is on the numerical inversion of two integral transforms, namely the spherical Radon and the cosine transform. Both transforms are frequently used in integral geometry and related fields, and their numerical inversion is needed in several applications.
To derive fast regularization schemes, the method of the approximate inverse is utilized. We introduce a new family of mollifiers and calculate the corresponding reconstruction kernels analytically for dimension d = 3 and even dimensions d ≥ 4.
Numerical results for the three-dimensional case are presented showing that the new class of mollifiers clearly improves the quality of the reconstruction in comparison to the Gaussian mollifier. Moreover, the regularization theory for the method is extended to a framework for arbitrary dimension d ≥ 3 (the special case d = 3 was already considered in [Inverse Problems 27 (2011), 035015]).

Functions of three open-palm hand gestures
Authors: Ferré Gaëlle 
Published: December 2013

AbstractThis study proposes an analysis of some pragmatic gestures with three types of open-palm gestures: beats and two instances of the hand flip, elsewhere called the ‘palm-up open-hand’ gesture (Müller, 2004; Cienki & Müller, 2008). Drawing upon three different corpora (political speeches made at the European Parliament, a television show in which the role of this parliament is presented and a corpus of conversational speech recorded in a lab), it proposes an analysis into prosodic, discursive and modal gestures. The paper - through the discussion of particular examples - will address the issues of the type of prosodic and discourse units which are marked by these gestures. Using the same methodological framework, the type of grammatical modality conveyed by open-palm gestures will also be considered.
Divorce: a visual essay
Authors: Norris Sigrid , Brandt Andrea 
Published: December 2013

AbstractThis visual essay incorporates poetry and paintings, telling a narrative about the stages of divorce that Andrea (retrospectively) experienced. The stages developed through this project were not lived as such, but rather are an analysis of past lived experience. The paintings, which were produced in 2011 embed poems that were written around the year 2000 during an ethnographic study on identity construction (Norris, 2011) in which Andrea was one of the participants. Back then, the researcher used poetry to jot down emotions of participants and other difficult-to-describe aspects encountered during ethnographic fieldwork. This year, we revisited the poems that came about because of Andrea’s divorce at the time, and illustrate our findings in this essay.
Can art (powerpoint) lead to social change? a mediated multimodal inquiry
Authors: Al Zidjaly Najma 
Published: December 2013

AbstractIn Al Zidjaly (2011a; 2011b), I bring together multimodality and disability research in a novel way, proposing a new approach to studying visual texts, especially works of art. This approach developed from my in-depth case study of the artistic and other everyday practices of one man with a disability, including how these practices are socially co-constructed and culturally situated (in the Arab nation of Oman). It encompasses conceptualizing works of art, following mediated discourse theory (Scollon 2001), as mediated actions carried out by social actors to achieve intended outcomes, rather than just as mere tools for self-expression or representation, as prior research has. Doing this, I argue, foregrounds the power that resides in images of disability, and by extension, in any other works of art or multimodal texts; it also highlights the agency that people with disabilities and other creators of works of art might have. In this article, I build on such research by further opening the circumference of analysis to demonstrate the compelling reciprocal relationship between art and societal change. I do so by examining not just how art created by an individual at the “micro” level can lead to social change at the “macro” level, but also how social change at the macro level affects individual artistic practices. The analysis has theoretical and practical implications for research on disability, multimodality and artistic expression.
Language verbalising notation: an intersemiotic analysis of musical notation in student texts
Authors: Martin Jodie L. 
Published: December 2013

AbstractMusic notation is a fundamental tool for conveying meanings in music and its interaction with verbal language provides valuable insight into musical discourse. The acquisition of both linguistic and notational literacy is important for the academic success of music students who must demonstrate their knowledge and ground their practise through written texts. This paper presents a framework adapted from Unsworth and Cléirigh (2009) for the intersemiotic analysis of language verbalising notation in student research texts. The analysis identifies the valued qualities of notation, the roles of both human and musical participants and the musical and textual circumstances of notational quotes. It further identifies manner and effect as contextually significant aspects generally outside the semiotic potential of notation which are presented in accompanying text. This paper draws on research into the academic literacies of jazz performance students to provide a descriptive foundation for the analysis of writing about music.
Two poems: The First Monday & The Book Lover
Authors: White Paul 
Published: December 2013

AbstractI was given a Kindle e-reader as a Christmas present in 2011. It got me thinking about the mediational means associated with reading. Then it got me thinking about the role books actually play as physical objects in describing our identities. The books on our shelves define us to a certain extent; the books we are seen reading in public suggests to others what kind of person we might be. The Book Lover was the poem that emerged, alonsgside other things. Around the same time, a copy of ‘Sing me the Creation’ by Paul Matthews was lying on a coffee table at a friend’s house. The cover features the 1810 painting ‘Adam naming the beasts’ by William Blake. I wrote First Monday as soon as I got home. Would that have happened if there had only been a Kindle on the coffee table?
Increasing Reading Engagement in African American Boys
Authors: Husband Terry 
Published: December 2013

Abstract
Much has written concerning the challenges many teachers face in engaging African American males in reading practices. While much of this extant scholarship focuses on African American males at the pre-adolescent stage of development and beyond, little has been written regarding increasing reading engagement in African American boys in P-5 contexts. Given this gap within the scholarship, the purpose of this article is to present a multi-strategic framework for increasing reading engagement in African American boys in early childhood and elementary contexts. Drawing from scholarship related to reading engagement, I discuss strategies for teachers to implement in and across curriculum, pedagogical, and school contexts to increase reading engagement in African American boys. I conclude with a discussion of three important commitments teachers must be willing to make for this framework to be successful.

It is no more new to see culturally and linguistically diverse (CLD) learners in our schools. The question then becomes, How do we improve their learning and behavioral outcomes? This article introduces the Special Issue of Multicultural Learning and Teaching (MLT) that presents ways to improve learning and behavioral outcomes of CLD learners.
Geopolymer ferrocement panels under flexural loading
Authors: Rajendran Mohana , Soundarapandian Nagan 
Published: December 2013

AbstractEfforts are needed to develop innovative and environmental friendly materials in order to reduce greenhouse gas emissions. An experimental investigation on the flexural behavior of thin cementless composite panels reinforced with welded rectangular wire mesh and chicken mesh with varying number of mesh layers as well as varying concentration of alkaline solution is presented. A total of 30 panels have been tested under flexural loading. The size of the panel is 1000 mm (length)×200 mm (width)×25/35 mm (thickness). The parameters studied in this investigation include varying the concentration of NaOH (8, 10, 12, 14 m) and thickness of composite panels. In this work, cement is replaced by geopolymer mix to bind the ferrocement skeletal framework and its flexural behavior is studied. It is concluded that the first crack and ultimate loads increase with the increase in the thickness of the element and the concentration of alkaline solution. From the studies, it is observed that the load-carrying capacities, energy absorption, and deformation at ultimate load are high in the case of geopolymer ferrocement element. Further, it is observed that there is reduction in crack width, and increase in number of cracks in the case of geopolymer ferrocement indicates delay in crack growth.
Combined effect of nano-SiO2 particles and steel fibers on flexural properties of concrete composite containing fly ash

Published: December 2013

Abstract
This paper presents an experimental study to evaluate the combined effect of nano-SiO2 particles and steel fibers on flexural properties of concrete composites containing fly ash. In this study, five different nano-SiO2 contents (1%, 3%, 5%, 7%, and 9%) and five different steel fiber contents (0.5%, 1%, 1.5%, 2%, and 2.5%) were used. The results indicate that addition of nano-SiO2 and steel fibers decreases the workability of the concrete composites containing fly ash, and both the slump and slump flow decrease gradually with the increase in nano-SiO2 and steel fiber content. Besides, the addition of nano-SiO2 can greatly increase the flexural strength and flexural modulus of elasticity of concrete composites containing fly ash. There is a tendency for the increase in the flexural strength flexural modulus of elasticity with an increase in the nano-SiO2 content when the nano-SiO2 content is below 5%, while both of the two flexural parameters begin to decrease after the nano-SiO2 content above 5%. Furthermore, steel fibers have great improvement on the flexural properties of concrete composites containing fly ash and nano-particles. The flexural strength and flexural modulus of elasticity of concrete composites containing fly ash and nano-SiO2 are more than those of the concrete composite without steel fibers. Both of the two flexural parameters increase with the increase in steel fiber content when the steel fiber content is below 2%, while the flexural parameters begin to decrease after the steel fiber content is above 2%.

Authors: Jafari-Talookolaei Ramazan-Ali , Abedi Maryam , Kargarnovin Mohammad H. , Ahmadian Mohammad T. 
Published: December 2013

AbstractThe free vibration analysis of generally laminated composite beam (LCB) with a delamination is presented using the finite element method (FEM). The effect of material couplings (bending-tension, bending-twist, and tension-twist couplings) with the effects of shear deformation, rotary inertia, and Poisson’s effect are taken into account. To verify the validity and the accuracy of this study, the numerical solutions are presented and compared with the results from available references and very good agreement observed. Furthermore, the effects of some parameters such as slenderness ratio, the rotary inertia, the shear deformation, material anisotropy, ply configuration, and delamination parameters on the natural frequency of the delaminated beam are examined.
Investigation of CFRP- and GFRP-confined concrete cylinders under monotonic and cyclic loading
Authors: Mortazavi Ali A. , Jalal Mostafa 
Published: December 2013

Abstract
Fiber reinforced polymer (FRP) composites have found increasingly wide applications in engineering due to their high strength-to-weight ratio and high corrosion resistance. One important application of FRP composites is as a confining material for concrete, which can enhance both the compressive strength and the ultimate axial strain of concrete. With this respect, the stress-strain behavior of FRP-confined concrete, under both monotonic and cyclic compression, needs to be properly understood and modeled. This paper presents details of an experimental work carried out on concrete cylinders wrapped with FRP materials and subjected to both monotonic and cyclic loading. A total number of 12 FRP confined concrete specimens and 10 control specimens with a diameter of 100 mm and a height of 200 mm were cast and cured under the same conditions, and two FRP materials (carbon fibers (CFRP) and glass fibers (GFRP)) were used for the construction of the FRP jackets. The effect of the type of confinement material, reinforcement ratio based on the jacket stiffness, and type of loading is examined. A model that predicts the behavior of confined concrete, which takes into account the stiffness and effectiveness of different confinement materials is also briefly introduced.
A semi-analytical three-dimensional free vibration analysis of functionally graded curved panels integrated with piezoelectric layers
Authors: Marzangoo Hamid Reza Saeidi , Jalal Mostafa 
Published: December 2013

Abstract
Free vibration analysis of functionally graded (FG) curved panels integrated with piezoelectric layers under various boundary conditions is studied. A panel with two opposite edges is simply supported, and arbitrary boundary conditions at the other edges are considered. Two different models of material property variations based on the power law distribution in terms of the volume fractions of the constituents and the exponential law distribution of the material properties through the thickness are considered. Based on the three-dimensional theory of elasticity, an approach combining the state space method and the differential quadrature method (DQM) is used. For the simply supported boundary conditions, closed-form solution is given by making use of the Fourier series expansion, and applying the differential quadrature method to the state space formulations along the axial direction, new state equations about state variables at discrete points are obtained for the other cases such as clamped or free-end conditions. Natural frequencies of the hybrid curved panels are presented by solving the eigenfrequency equation, which can be obtained by using edges boundary conditions in this state equation. The results obtained for only FGM shell is verified by comparing the natural frequencies with the results obtained in the literature.
Second to fourth digits ratio (2D:4D) and subjective pain experience in tattooing
Authors: Kozieł Sławomir , Chakraborty Raja , Sitek Aneta 
Published: December 2013

This aims of this research are to determine if the 2D:4D digit ratio is related to subjective pain experience during tattooing and to examine gender differences therein. The study involved 43 male and 28 female Polish adults recruited from two tattoo salons in Wroclaw and Leszno in Western Poland. These subjects were asked if they felt pain during their tattooing and answers were recorded as ‘Yes’ or ‘No’.
The ventral surface lengths of the second and fourth digits of each hand were measured, and analysis of variance was performed to assess significant differences in the 2D:4D ratios of right and left hands and two- hand averages between genders and the Yes/ No groups reporting pain experience. Results revealed that although the digit ratios for females had systematically higher values than those in males, differences were not statistically significant. Both sex and subjective pain feeling were significantly associated with 2D:4D ratio in both hands and their average values, while sex and pain experience were independently associated with digit ratio. Subjects who felt pain during tattooing had a significantly lower digit ratio. In conclusion, the study did not support the hypothesis that the lower masculine 2D:4D ratio is associated with a higher pain threshold. Prenatal sex hormonal exposure generating the gender dimorphic 2D:4D index may not predispose the actual feeling of all kinds of pain; in this instance, not in pain associated with tattooing.
