Gender Differences in the Corporate Social Responsibility Orientation of Credit Union Board Members

Credit unions serve an important purpose in the U.S. economy by providing financial services to low- and moderate-income individuals. Their assets have steadily grown from $217 billion to$655 billion between 1990 and 2004. In spite of these impressive growth rates, a number of writers have expressed great concern regarding credit union governance, particularly over the role and functions of the board\u27s members. More recently, the financial crisis has raised important questions regarding the board\u27s level of involvement and its ethical and social responsibilities in corporate decision making. One area which has remained relatively unexplored concerns the attitudes of credit union board members toward corporate social responsibility. Furthermore, to date very little is known regarding the extent of similarities and differences between these organizations\u27 male and female board members with respect to this issue. The present study was designed to investigate this issue. A survey of 470 directors of 80 credit unions revealed significant differences between the genders with respect to the legal and ethical components of corporate social responsibility. Compared to their male counterparts, the female directors exhibited greater concern about the legal dimension of corporate responsibility and a weaker orientation toward ethics. No significant differences between the two groups were observed with respect to the economic and discretionary components

The Balanced Two-String Technique for Sulcus Intraocular Lens Implantation in the Absence of Capsular Support

Purpose. To describe and explore an alternative approach for sulcus intraocular lens (IOL) implantation in the absence of capsular support. Methods. The commonly available one-piece poly(methyl methacrylate) (PMMA) lens is stabilized in the sulcus by two intraocular horizontal strings of 10/0 polypropylene suture passed through the lens dialing holes in opposite directions to achieve a mechanical balance. The horizontal strings of 10/0 polypropylene work as a rail track for the IOL optics, allowing some side to side lens adjustment even following wound closure. The stability of the IOL was tested in vitro. Six aphakic patients underwent in-sulcus IOL secondary implantation using the balanced two-string technique. Patients were followed up for a minimum of six months. Best spectacle corrected vision was assessed. Lens centration and lens tilt were measured by anterior segment optical coherence tomography (AS-OCT). Results. All patients had successful lens insertion. Best spectacle corrected visual acuity (BSCVA) improved in all patients. Lens decentration ranged between 0.21 mm and 0.9 mm (average 0.53 mm). Lens tilt ranged between 1.2° and 2.8° (average 2.17°). Conclusion. The mechanically balanced two-string technique is an alternative option for sulcus IOL implantation in absence of capsular support, allowing lens centration adjustment with no additional risks

Service-Learning Projects Enhance Student Learning in Strategic Management Courses

Academia has been criticized for Its supposed isolation from society and its lack of emphasis on practical applications and hands-on experience. Institutions of higher education are responding to this criticism by incorporating experiential service-learning in their curricula. One business course which is particularly appropriate for integrating service-learning into the curriculum is Strategic Management

A Multiple-Objective Environmental Rationalization and Optimization for Material Substitution in the Production of Stone-Washed Jeans- Garments

As the Textile Industry is the second largest industry in Egypt and as small and medium-sized enterprises (SMEs) make up a great portion of this industry therein it is essential to apply the concept of Cleaner Production for the purpose of reducing pollution. In order to achieve this goal, a case study concerned with ecofriendly stone-washing of jeans-garments was investigated. A raw material-substitution option was adopted whereby the toxic potassium permanganate and sodium sulfide were replaced by the environmentally compatible hydrogen peroxide and glucose respectively where the concentrations of both replaced chemicals together with the operating time were optimized. In addition, a process-rationalization option involving four additional processes was investigated. By means of criteria such as product quality, effluent analysis, mass and heat balance; and cost analysis with the aid of a statistical model, a process optimization treatment revealed that the superior process optima were 50%, 0.15% and 50min for H2O2 concentration, glucose concentration and time, respectively. With these values the superior process ought to reduce the annual cost by about EGP 105 relative to the currently used conventional method

Parameter estimation of electric power transformers using Coyote Optimization Algorithm with experimental verification

In this work, the Coyote Optimization Algorithm (COA) is implemented for estimating the parameters of single and three-phase power transformers. The estimation process is employed on the basis of the manufacturer's operation reports. The COA is assessed with the aid of the deviation between the actual and the estimated parameters as the main objective function. Further, the COA is compared with well-known optimization algorithms i.e. particle swarm and Jaya optimization algorithms. Moreover, experimental verifications are carried out on 4 kVA, 380/380 V, three-phase transformer and 1 kVA, 230/230 V, single-phase transformer. The obtained results prove the effectiveness and capability of the proposed COA. According to the obtained results, COA has the ability and stability to identify the accurate optimal parameters in case of both single phase and three phase transformers; thus accurate performance of the transformers is achieved. The estimated parameters using COA lead to the highest closeness to the experimental measured parameters that realizes the best agreements between the estimated parameters and the actual parameters compared with other optimization algorithms

Extent Of Director Involvement In The Strategic Management Process: Does Occupational Background Make A Difference?

Propositions were tested with original survey data from 224 directors from nineteen hospitals to determine the extent of their involvement in the strategic management process. In most areas, board members whose occupational background is in health care tend to be less engaged than their counterparts whose background is not in health care. Significant differences were observed with respect to broad cross-functional strategic issues and overall hospital performance.  Both groups had limited involvement in setting standards for rewarding top management and evaluating their performance.  The results raise potentially important strategic and ethical dilemmas for hospitals and offer proponents of changes in board composition support for their normative suggestions.   &nbsp

EXTENT OF HOSPITAL DIRECTOR INVOLVEMENT IN STRATEGIC MANAGEMENT: DOES TENURE MAKE A DIFFERENCE?

Of particular interest to researchers and practitioners is the impact of board members\u27 composition and characteristics on corporate activities. With the exception of studies focusing on the gender of board members and the inside director-outside director dichotomy, much of the research tends to treat directors as a homogeneous group. This study seeks to determine whether a relationship exists between hospital directors\u27 length of tenure and their degree of involvement in the strategic management process. The results of a survey of 240 directors from twenty-one hospitals are analyzed. A MANOVA, followed by a series of ANOVAs revealed significant differences between the long- and short-tenure directors. In most areas those with relatively short board tenure tend to be less engaged than their longer-tenured counterparts. The latter are more involved in developing strategic alternatives, providing advice and counsel in discussions outside of board/committee meetings, and setting standards for and evaluating the performance of the hospital and management. However, both groups have very limited involvement in setting standards for rewarding top management and evaluating their performance. Short-tenure directors are more concerned with the interests of major stakeholders and promoting their goodwill and support. Also, they are more actively involved in financial matters. The results raise potentially important strategic dilemmas for hospitals and offer proponents of changes in board composition support for their normative suggestions. Longer-tenured members are not as concerned with financial matters as well as stakeholders\u27 interests and support as their short-tenured counterparts. Also, although longer-tenured members were more active in setting standards for rewarding top management and assessing their performance, it is important to note the limited involvement of both groups. The results show a reluctance by both groups to set performance standards for top management and to formally evaluate their performance

Effect of Lipid Headgroup Charge and pH on the Stability and Membrane Insertion Potential of Calcium Condensed Gene Complexes

This document is the Accepted Manuscript version of a Published Work that appeared in final form in Langmuir, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://doi.org/10.1021/la504970n.Noncovalently condensed complexes of genetic material, cell penetrating peptides (CPPs), and calcium chloride present a nonviral route to improve transfection efficiency of nucleic acids (e.g., pDNA and siRNA). However, the exact mechanisms of membrane insertion and delivery of macromolecule complexes to intracellular locations as well as their stability in the intracellular environment are not understood. We show that calcium condensed gene complexes containing different hydrophilic (i.e., dTAT, K9, R9, and RH9) and amphiphilic (i.e., RA9, RL9, and RW9) CPPs formed stable cationic complexes of hydrodynamic radii 100 nm at neutral pH. However, increasing the acidity caused the complexes to become neutral or anionic and increase in size. Using zwitterionic and anionic phospholipid monolayers as models that mimic the membrane composition of the outer leaflet of cell membranes and intracellular vesicles and pHs that mimic the intracellular environment, we study the membrane insertion potential of these seven gene complexes (CPP/pDNA/Ca2+ complexes) into model membranes. At neutral pH, all gene complexes demonstrated the highest insertion potential into anionic phospholipid membranes, with complexes containing amphiphilic peptides showing the maximum insertion. However, at acidic pH, the gene complexes demonstrated maximum monolayer insertion into zwitterionic lipids, irrespective of the chemical composition of the CPP in the complexes. Our results suggest

Numerical estimation and experimental verification of optimal parameter identification based on modern optimization of a three phase induction motor

The parameters of electric machines play a substantial role in the control system which, in turn, has a great impact on machine performance. In this paper, a proposed optimal estimation method for the electrical parameters of induction motors is presented. The proposed method uses the particle swarm optimization (PSO) technique. Further, it also considers the influence of temperature on the stator resistance. A complete experimental setup was constructed to validate the proposed method. The estimated electrical parameters of a 3.8-hp induction motor are compared with the measured values. A heat run test was performed to compare the effect of temperature on the stator resistance based on the proposed estimation method and the experimental measurements at the same conditions. It is shown that acceptable accuracy between the simulated results and the experimental measurements has been achieved

Influence of blend ratio on the electrical characteristics of vulcanized SBR/NBR blends compatibilized by Cis-polybutadiene rubber

Blends composed of styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) have been fabricated by melt-blending technique using two-roll mill blend machine. Cis-polybutadiene rubber (CBR) was used as a compatibilizer for enhancing the homogeneity between blend phases. No previous reports were found to discuss improving electrical properties of vulcanized SBR/NBR blends using unfilled rubber system (i.e. no fillers incorporation). SEM micrographs were utilized to verify the compatibility between two rubber ingredients in various blends, owing to the use of compatibilizer. Thermal stability of blends was investigated by differential thermal analysis (DTA) and differential scanning calorimetric (DSC) to evaluate the influence of blend ratio on the compatibility of investigated samples. Results revealed that the dielectric properties of blends are dramatically influenced by altering the blend ratio. The results revealed that the SEM observations confirmed the compatibilization effect of CBR on vulcanized SBR/NBR blends. Meanwhile, thermal properties of vulcanized SBR/NBR blends were enhanced with increasing of SBR contents in blends. The complex impedance graphs showed circular arcs showing the bulk contribution to overall electrical behavior for investigated vulcanized SBR/NBR blends. During I-V characteristics have been presented, where a remarkably change from linear behavior to nonlinear conduction at lower temperatures was found for 0SBR/100NBR blends. These findings supported and confirmed that the compatibilization effect and the blend ratio between rubber compositions have strongly influenced on their thermal and electrical properties of vulcanized blends
