The Trans-Pacific Partnership Agreement and the Changing Face of Free Trade Agreements: The Resultant Social, Political, and Economic Consequences

Little is known about the impact of nontrade issues on developing countries entering trade agreements. The Trans-Pacific Partnership Agreement (TPPA) represents an attempt to set high-standard trade rules for participating countries in the Asian-Pacific region that require the inclusion of wide-ranging nontrade issues in the TPPA. This general qualitative study explored the economic, social, and political consequences for developing countries by including nontrade issues in Free Trade Agreements (FTAs). The overarching research question addressed whether nontrade issues in FTAs detract developing countries from achieving their trade goals. This study was guided by the theory of comparative advantage propounded by Ricardo and the focus on trade in goods and services. This general qualitative study used multiple sources of data collection including documentation-primary and secondary online and digital archival data, bibliographies, textbooks, and scholarly trade journals; researcher\u27s notes; and interviews of 15 participants (13 economists and 2 trade unionists). All data were coded using open, selective, and axial coding followed by Braun and Clarke\u27s thematic analysis procedure. Data analysis revealed 4 themes that crystallized the findings within the context of the research; the role, ramifications of nontrade issues, trade barriers, and the distraction of developing countries from achieving their goals-tariff reductions, market access, jobs, and economic growth. The key finding of this study was the interest of participants in wages, health, and safety of workers in FTAs. The implications for positive social change include recommendations for welfare enhancement gained by trade policymakers\u27 understanding of the consequences of nontrade issues in FTAs

An Adaptive Wood Composite: Theory

A theoretical model is presented for the steady-state and transient behavior of adaptive wood composite plates composed of layers of wood and other piezoelectric materials. Effects of the mechanical, electrical, temperature, and moisture fields are studied simultaneously using a discrete-layer model of the governing equations. These are solved using the finite element method. The computational model employs a one-dimensional Lagrange linear interpolation function in the through-thickness direction and two-dimensional quadratic finite element for the in-plane approximations, treating the displacements, potential, temperature, and moisture as the nodal unknowns. Representative examples of adaptive wood composites are modeled and potential applications are discussed

Predicting Small Bank Failure

There are many studies of bank performance and bank failure in the literature. Most of these studies used banking ratios as variables in their models without giving consideration to their appropriateness, nor was much consideration given to the stability of those ratios through time and across asset size. Many studies also failed to recognize that bank structure may differ by asset size. This study evaluates a large number of banking variables in order to identify stable ratios. These ratios are then used in disaggregated logistic models to predict bank failure. The study finds that the disaggregated models with stable variables were better predictors of bank failure than aggregated models used in earlier studies

A Tale of Two Blogs: Lessons Learned Establishing The Top Shelf and La Cocina Histórica at the University of Texas at San Antonio

When establishing a blog, Special Collections departments face a variety of decisions that will affect the future shape of the blog and its readership. The University of Texas at San Antonio (UTSA) Libraries Special Collections is in the unusual position of publishing two blogs with distinct audiences and content: a general department blog, The Top Shelf, and a collection-specific blog, La Cocina Histórica. This article examines various strategies employed by both of these blogs in the areas of content, targeted audience, management and authorship responsibility, media exposure, and platform-choice and how those strategies affect blog readership

Areas Of Cross-Cultural Difference In The Workplace

In the last 30 years, there has been a shift towards using multicultural management strategies. The constant shifts taking place in multi-ethnic, multicultural, and multinational workforces indicate that both administrators of these organizations and higher education practices must evolve to adapt to needs for changing skill sets. A multicultural workforce offers advantages in that businesses may reach out effectively to various stakeholders. Leaders do well to cultivate an organizational culture that incorporates flexibility, understanding, and acceptance of alternate values, especially when working in foreign locations or multi-national organizations. Understanding of differences in cultural values and customs may reduce conflict and increase collaboration. To meet these challenges, leaders must be trained and educated to develop flexibility, understanding, and acceptance of alternate values when working in foreign locations or multi-national organizations. This article points out important areas of difference for organizations to address

Discrete-Layer Piezoelectric Plate and Shell Models for Active Tip-Clearance Control

The objectives of this work were to develop computational tools for the analysis of active-sensory composite structures with added or embedded piezoelectric layers. The targeted application for this class of smart composite laminates and the analytical development is the accomplishment of active tip-clearance control in turbomachinery components. Two distinct theories and analytical models were developed and explored under this contract: (1) a discrete-layer plate theory and corresponding computational models, and (2) a three dimensional general discrete-layer element generated in curvilinear coordinates for modeling laminated composite piezoelectric shells. Both models were developed from the complete electromechanical constitutive relations of piezoelectric materials, and incorporate both displacements and potentials as state variables. This report describes the development and results of these models. The discrete-layer theories imply that the displacement field and electrostatic potential through-the-thickness of the laminate are described over an individual layer rather than as a smeared function over the thickness of the entire plate or shell thickness. This is especially crucial for composites with embedded piezoelectric layers, as the actuating and sensing elements within these layers are poorly represented by effective or smeared properties. Linear Lagrange interpolation polynomials were used to describe the through-thickness laminate behavior. Both analytic and finite element approximations were used in the plane or surface of the structure. In this context, theoretical developments are presented for the discrete-layer plate theory, the discrete-layer shell theory, and the formulation of an exact solution for simply-supported piezoelectric plates. Finally, evaluations and results from a number of separate examples are presented for the static and dynamic analysis of the plate geometry. Comparisons between the different approaches are provided when possible, and initial conclusions regarding the accuracy and limitations of these models are given

Capactitive probe array measurements and limitations

This paper reviews the use of electrostatic capacitive probes for detections and evaluations of dielectric material properties and flaws. Interest in using both inductive and capacitive arrays for proximity sensing, surface feature characterization, material properties evaluation, and flaw detecting has increased steadily since the mid-1980’s [1–7]. Two other papers [6,7] in this proceedings also discuss the present state of the art, particularly with regard to the measurement of lossy dielectrics (complex permittivity). In traditional dielectrometry measurements (as well as in eddy-current measurements of material properties evaluation) varying the probe frequency has long been used as a tool for extracting information about dispersion and loss mechanisms. Use of a spatially periodic array probe interrogates the material, or flaw, with a field that penetrates into the sample to a degree determined by the periodicity. This controllable penetration phenomenon (artificial-skin effect or zoom effect) has been successfully exploited by Melcher, Zaretsky [5], and Goldfine [6] in what they call imposed w-k magnetometry and dielectrometry, using interdigital probes of different periodicities. Details are given in these proceedings. Gammell’s paper [7] gives a progress report on complex permittivity measurements using probes of more conventional type

Layerwise mechanics and finite element for the dynamic analysis of piezoelectric composite plates

Laminate and structural mechanics for the analysis of laminated composite plate structures with piezoelectric actuators and sensors are presented. The theories implement layerwise representations of displacements and electric potential, and can model both the global and local electromechanical response of smart composite laminates. Finite-element formulations are developed for the quasi-static and dynamic analysis of smart composite structures containing piezoelectric layers. Comparisons with an exact solution illustrate the accuracy, robustness and capability of the developed mechanics to capture the global and local response of thin and/or thick laminated piezoelectric plates. Additional correlations and numerical applications demonstrate the unique capabilities of the mechanics in analyzing the static and free-vibration response of composite plates with distributed piezoelectric actuators and sensors

On the flexural vibration of cylinders under axial loads:Numerical and experimental study

The flexural vibration of a homogeneous isotropic linearly elastic cylinder of any aspect ratio is analysed in this paper. Natural frequencies of a cylinder under uniformly distributed axial loads acting on its bases are calculated numerically by the Ritz method with terms of power series in the coordinate directions as approximating functions. The effect of axial loads on the flexural vibration cannot be described by applying infinitesimal strain theory, therefore, geometrically nonlinear strain–displacement relations with second-order terms are considered here. The natural frequencies of free–free, clamped–clamped, and sliding–sliding cylinders subjected to axial loads are calculated using the proposed three-dimensional Ritz approach and are compared with those obtained with the finite element method and the Bernoulli–Euler theory. Different experiments with cylinders axially compressed by a hydraulic press are carried out and the experimental results for the lowest flexural frequency are compared with the numerical results. An approach based on the Ritz formulation is proposed for the flexural vibration of a cylinder between the platens of the press with constraints varying with the intensity of the compression. The results show that for low compressions the cylinder behaves similarly to a sliding–sliding cylinder, whereas for high compressions the cylinder vibrates as a clamped–clamped one
