An Investigation Of The Erosion In New Major Innovation Characteristics Over Time

A recent study by ODonnell and Sauer (2008) indicated, that over time, the benefit of launching new majors to reduce freshman attrition dissipated. In 2004, new majors had a significant effect on reducing attrition. By 2007, however, these same new majors were no longer significant predictors of attrition. What happened between 2004 and 2007 to cause this erosion in the affect of new majors on attrition? In this study, we examine the differences in perceptions of the innovative characteristics in an effort to explain why this erosion might have occurred. Results of a two-way between subjects ANOVA reveals that new majors began to be perceived as similar to old majors along certain dimensions of innovative characteristics. In particular, differences in the prospects of getting a better job, the perception that the new major was easier, hearing from others that new majors offered better job prospects and that employers preferred new majors, and that new majors were less compatible with student needs and goals, all disappeared by 2007. Nevertheless, new majors were still perceived as requiring more prerequisites, being more likely to require an extra course, and as not being offered at other area colleges and universities relative to old majors. This article discusses the impact and consequences of these findings and proposes future research to be pursued

Innovation Constructs: An Exploratory Study

Many organizations strive to improve performance by creating and marketing new products and/or services. Understanding why some new products and services succeed while others fail is critical to managers and marketing researchers. Diffusion of innovation theory addresses the reasons for, and rate of, the adoption of new ideas, products, and services. This theory and its related constructs have been successfully applied to new products while there has been less on emphasis on new services such as educational innovations. Further, research of educational innovations, has focused on adoption by teachers and administrators rather than students. This research study addresses this gap by empirically investigating whether diffusion of innovation theory and constructs apply to student adoption of new academic programs.  

A Logistic Regression Model For The Enhancement Of Student Retention: The Identification Of At-Risk Freshmen

A logistic regression model will be developed to provide early identification of freshmen at risk of attrition.  The early identification is accomplished literally within a couple of weeks after freshman orientation.  The dependent variable of interest is persistence, and it is a binary, nominal variable.  Students who proceed from freshman matriculation to graduation without ever having dropped out are labeled persistors.  Freshman matriculates who leave college either temporarily or permanently are classified as dropouts.  The independent variables employed to predict attrition include demographics, high school experiences, and attitudes, opinions, and values as reported on a survey administered during freshman orientation.  The model and its results will be presented along with a brief description of the institutional intervention program designed to enhance student persistence

Persist/Dropout Differences In Pre-matriculation Attitudes Of Freshman Towards College Attrition: A Longitudinal Multiple Group Structural Equations Model

This study proposes a structural equations model of college student attrition based on pre-matriculation freshman attitudes. The study uses a survey administered annually from 1995 to 1999 and tracks persistence and dropout behavior for five years until the last cohort graduated. It discusses seven constructs of pre-matriculation freshman attitudes that resemble the Cabrera, Nora, and Castañeda (1993) model of College Persistence that was based on attitudes of first-to-second year enrolled college students. We applied our survey to a Northeastern sectarian private college. Our model includes external factors such as financial attitude, and endogenous variables such as academic reputation, social integration, institutional commitment, goal commitment, academic performance, and intent to persist. In addition to the variables related to the Cabrera model, we added two measures of social integration, “political interests” and “concern-for the disadvantaged” because these were suitable to the type of college which hosted the study. Results provide a multiple group comparative and predictive model of student attrition for annual use by the Dean of Student Affairs in designing proactive plans and implementing intervention strategies to enhance student retention

Anticipating issues related to increasing preimplantation genetic diagnosis use: a research agenda

Increasing use of preimplantation genetic diagnosis (PGD) poses numerous clinical, social, psychological, ethical, legal and policy dilemmas, many of which have received little attention. Patients and providers are now considering and using PGD for a widening array of genetic disorders, and patients may increasingly seek ‘designer babies.’ In the USA, although governmental oversight policies have been discussed, few specific guidelines exist. Hence, increasingly, patients and providers will face challenging ethical and policy questions of when and for whom to use PGD, and how it should be financed. These issues should be better clarified and addressed through collection of data concerning the current use of PGD in the USA, including factors involved in decision making about PGD use, as well as the education of the various communities that are, and should be, involved in its implementation. Improved understanding of these issues will ultimately enhance the development and implementation of future clinical guidelines and policies

Drivers of attitudes towards luxury brands: A cross-national investigation into the roles of interpersonal influence and brand consciousness

Purpose - Limited attention has been paid to the cultural influences on the formation of consumer attitudes toward luxury brands (LUX). The current study investigates this relationship by developing a model that additionally employs the constructs of susceptibility to normative interpersonal influence (SNII) and brand consciousness (BCO). Design/methodology/approach - Sample data were gathered through surveys administered to 383 college students in the United Kingdom (UK) and Taiwan. The model of cultural influences on attitudes toward luxury brands was empirically tested using multi-group structural equation modeling to evaluate its applicability across the two countries. Findings - Results are presented in two parts: 1) the exogenous construct part of the model establishing the reliability and validity of the cultural dimension constructs (horizontal individualism, vertical individualism, horizontal collectivism, and vertical collectivism) that are antecedent to consumer SNII and 2) the endogenous part of the model in which consumer SNII affects LUX through the mediating role of BCO. Research limitations/implications - The findings in the current study are limited to a sample of college students in the UK and Taiwan, which, through representing Western and Asian countries, each housing different cultures, do not span the greater number of cultures found across these countries, much less across the world. Furthermore it is assumed that there are a number of subcultures in both the UK and Taiwan that are not accounted for in this study. Practical implications - An individual level of cultural orientation (e.g. horizontalism and verticalism) rather than traditionally adopted regionally-defined or nationally-based (Hofstede, 1980) cultural criteria should be investigated to identify more accurate market demand patterns in order to best target consumers in these markets (Sharma, 2010). In addition, appealing, vertical ad messages would be more effective in stimulating consumer motivations for consumption of luxury brands. Conversely, horizontal ad messages would be effective in demarketing approaches. Originality/value - The current study is the first of its kind to explore the effect of cultural-orientation on the formation of LUX cross-nationally. As such it provides future cross-cultural researchers with valid and reliable culturally-based constructs that can be used to predict consumer SNII in developing LUX. In addition, establishing the mediating role of BCO in the relationship between SNII and LUX helps marketers better understand the equity of their luxury brands, particularly in Asian countries

Cryptic species and parallel genetic structuring in Lethrinid fish:Implications for conservation and management in the southwest Indian Ocean

Analysis of genetic variation can provide insights into ecological and evolutionary diversification which, for commercially harvested species, can also be relevant to the implementation of spatial management strategies and sustainability. In comparison with other marine biodiversity hot spots, there has been less genetic research on the fauna of the southwest Indian Ocean (SWIO). This is epitomized by the lack of information for lethrinid fish, which support socioeconomically important fisheries in the region. This study combines comparative phylogeographic and population genetic analyses with ecological niche modeling to investigate historical and contemporary population dynamics of two species of emperor fish (Lethrinus mahsena and Lethrinus harak) across the SWIO. Both species shared similarly shallow phylogeographic patterns and modeled historical (LGM) habitat occupancies. For both species, allele frequency and kinship analyses of microsatellite variation revealed highly significant structure with no clear geographical pattern and nonrandom genetic relatedness among individuals within samples. The genetic patterns for both species indicate recurrent processes within the region that prevent genetic mixing, at least on timescales of interest to fishery managers, and the potential roles of recruitment variability and population isolation are discussed in light of biological and environmental information. This consistency in both historical and recurrent population processes indicates that the use of model species may be valuable in management initiatives with finite resources to predict population structure, at least in cases wherein biogeographic and ecological differences between taxa are minimized. Paradoxically, mtDNA sequencing and microsatellite analysis of samples from the Seychelles revealed a potential cryptic species occurring in sympatry with, and seemingly morphologically identical to, L. mahsena. BLAST results point to the likely misidentification of species and incongruence between voucher specimens, DNA barcodes, and taxonomy within the group, which highlights the utility and necessity of genetic approaches to characterize baseline biodiversity in the region before such model-based methods are employedpublishersversionPeer reviewe

Preimplantation genetic diagnosis on in vitro fertilization clinic websites: presentations of risks, benefits and other information

Objective: To examine information on preimplantation genetic diagnosis (PGD) presented on IVF clinic websites. Design: We systematically sampled every third IVF clinic on the 2004 Centers for Disease Control provider list. Setting: The Internet. Patient(s): None. Intervention(s): None. Main Outcome Measure(s): Benefits, risks, and other types of information mentioned regarding PGD. Result(s): Of 135 sites examined, 88.1% had websites, and 70% mentioned PGD, of which 27% were university- or hospital-based and 63% were private clinics. Sites mentioning PGD listed uses and benefits of PGD far more than the risks involved. Of these sites, 76% described testing for single-gene diseases, but fewer mentioned risks of missing target diagnoses (35%) or risks for loss of embryo (18%), and 14% described PGD as new or controversial. Private clinics were more likely than other programs to be on either the East or West Coast, list certain PGD risks (e.g., diagnostic error), note that PGD was new or controversial, reference source of PGD information, provide accuracy rates of genetic testing of embryos, and offer gender selection for social reasons. Conclusion(s): Most IVF clinics advertise PGD online, but the scope and quality of information about it varies widely, emphasizing benefits while minimizing risks. Clinics and patients may benefit from more thorough and consistent presentation of PGD, drawing on available evidence to best provide a realistic portrayal of PGD
