Costly Ignorance: The Denial of Relevance by Job Seekers: A Case Study in Saudi Arabia

Description: Job centers aid businesses seeking qualified employees and assist job seekers to select and contact employment and training services. Job seekers are also offered the opportunity to assess their skills, abilities, qualifications, and readiness. Furthermore, job centers ensure that job seekers are complying with requirements that they must meet to benefit from job assistance programs such as unemployment insurance. Yet, claimants often procrastinate and/or suspend their job search efforts even though such actions can make them lose their free time and entitlements, and more importantly they may lose the opportunity to take advantage of free information, services, training, and financial assistance for getting a job to which they have already made a claim. The current work looks to Chatman's "small worlds" work, Johnson's comprehensive model of information seeking, and Wilson's "costly ignorance" construct for contributions to understanding such behavior. Identification of a particular trait or set of traits of job seekers during periods of unemployment will inform a new Job Seeking Activities Model (JSAM). This study purposely examines job seeker information behavior and the factors which influence job seekers' behavior, in particular, family tangible support as a social norm effect. A mixed method, using questionnaires for job hunting completers and non-completers and interviews for experts, was employed for data collection. Quantitative data analysis was conducted to provide the Cronbach α coefficient, Pearson's product moment correlation, an independent-sample t-test, effect size, and binary Logit regression. The qualitative data generated from the interview transcript for each section of the themes and subthemes were color coded. Finally, simultaneous triangulation was carried out to confirm or contradict the results from each method. The findings show that social norms, particularly uncontrolled social support provided by their families, are more likely to make job seekers ignore the relevant information about jobs available to them in favor ...

Coyote Ugly Librarian: A Participant Observer Examination of Lnowledge Construction in Reality TV.

Description: Reality TV is the most popular genre of television programming today. The number of reality television shows has grown exponentially over the last fifteen years since the premier of The Real World in 1992. Although reality TV uses styles similar to those used in documentary film, the “reality” of the shows is questioned by critics and viewers alike. The current study focuses on the “reality” that is presented to viewers and how that “reality” is created and may differ from what the participants of the shows experience. I appeared on two reality shows, Faking It and That's Clever, and learned a great deal as a participant observer. Within the study, I outline my experience and demonstrate how editing changed the reality I experienced into what was presented to the viewers. O'Connor's (1996) representation context web serves as a model for the realities created through reality television. People derive various benefits from watching reality TV. Besides the obvious entertainment value of reality TV, viewers also gather information via this type of programming. Viewers want to see real people on television reacting to unusual circumstances without the use of scripts. By surveying reality TV show viewers and participants, this study gives insight into how real the viewers believe the shows are and how authentic they actually are. If these shows are presented as reality, viewers are probably taking what they see as historical fact. The results of the study indicate more must be done so that the “reality” of reality TV does not misinform viewers.

Creating a Criterion-Based Information Agent Through Data Mining for Automated Identification of Scholarly Research on the World Wide Web

Description: This dissertation creates an information agent that correctly identifies Web pages containing scholarly research approximately 96% of the time. It does this by analyzing the Web page with a set of criteria, and then uses a classification tree to arrive at a decision. The criteria were gathered from the literature on selecting print and electronic materials for academic libraries. A Delphi study was done with an international panel of librarians to expand and refine the criteria until a list of 41 operationalizable criteria was agreed upon. A Perl program was then designed to analyze a Web page and determine a numerical value for each criterion. A large collection of Web pages was gathered comprising 5,000 pages that contain the full work of scholarly research and 5,000 random pages, representative of user searches, which do not contain scholarly research. Datasets were built by running the Perl program on these Web pages. The datasets were split into model building and testing sets. Data mining was then used to create different classification models. Four techniques were used: logistic regression, nonparametric discriminant analysis, classification trees, and neural networks. The models were created with the model datasets and then tested against the test dataset. Precision and recall were used to judge the effectiveness of each model. In addition, a set of pages that were difficult to classify because of their similarity to scholarly research was gathered and classified with the models. The classification tree created the most effective classification model, with a precision ratio of 96% and a recall ratio of 95.6%. However, logistic regression created a model that was able to correctly classify more of the problematic pages. This agent can be used to create a database of scholarly research published on the Web. In addition, the technique can be used to create a ...

CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

Description: The problem with which this study is concerned is articulating all possible CT3 and KR21 reliability measures for every case of a 5x5 binary matrix (32,996,500 possible matrices). The study has three purposes. The first purpose is to calculate CT3 for every matrix and compare the results to the proposed optimum range of .3 to .5. The second purpose is to compare the results from the calculation of KR21 and CT3 reliability measures. The third purpose is to calculate CT3 and KR21 on every strand of a class test whose item set has been reduced using the difficulty strata identified by Order Analysis. The study was conducted by writing a computer program to articulate all possible 5 x 5 matrices. The program also calculated CT3 and KR21 reliability measures for each matrix. The nonparametric technique of Order Analysis was applied to two sections of test items to stratify the items into difficulty levels. The difficulty levels were used to reduce the item set from 22 to 9 items. All possible strands or chains of these items were identified so that both reliability measures (CT3 and KR21) could be calculated. One major finding of this study indicates that .3 to .5 is a desirable range for CT3 (cumulative p=.86 to p=.98) if cumulative frequencies are measured. A second major finding is that the KR21 reliability measure produced an invalid result more than half the time. The last major finding is that CT3, rescaled to range between 0 and 1, supports De Vellis' guidelines for reliability measures. The major conclusion is that CT3 is a better measure of reliability since it considers both inter- and intra-item variances.

Customers' Attitudes toward Mobile Banking Applications in Saudi Arabia

Description: Mobile banking services have changed the design and delivery of financial services and the whole banking sector. Financial service companies employ mobile banking applications as new alternative channels to increase customers' convenience and to reduce costs and maintain profitability. The primary focus of this study was to explore the Saudi bank customers' perceptions about the adoption of mobile banking applications and to test the relationships between the factors that influence mobile banking adoption as independent variables and the action to adopt them as the dependent variable. Saudi customers' perceptions were tested based on the extended versions of IDT, TAM and other diffusion of innovation theories and frameworks to generate a model of constructs that can be used to study the use and the adoption of mobile technology by users. Koenig-Lewis, Palmer, & Moll's (2010) model was used to test its constructs of (1) perceived usefulness, (2) perceived ease of use, (3) perceived compatibility, (4) perceived credibility, (5) perceived trust, (6) perceived risk, and (7) perceived cost, and these were the independent variables in current study. This study revealed a high level of adoption that 82.7% of Saudis had adopted mobile banking applications. Also, the findings of this study identified a statistically significant relationship between all of demographic differences: gender, education level, monthly income, and profession and mobile banking services among adopters and non-adopters. Seven attributes relating to the adoption of mobile banking applications were evaluated in this study to assess which variables affected Saudi banks customers in their adoption of mobile banking services. The findings indicated that the attributes that significantly affected the adoption of mobile banking applications among Saudis were perceived trust, perceived cost, and perceived risk. These three predictors, as a result, explained more than 60% of variance in intention to adopt mobile banking technology in Saudi Arabia. ...

The Denial of Relevance: Biography of a Quest(ion) Amidst the Min(d)fields—Groping and Stumbling

Description: Early research on just why it might be the case that “the mass of men lead lives of quiet desperation” suggested that denial of relevance was a significant factor. Asking why denial of relevance would be significant and how it might be resolved began to raise issues of the very nature of questions. Pursuing the nature of questions, in light of denial of relevance and Thoreau’s “quiet desperation” provoked a journey of modeling questions and constructing a biography of the initial question of this research and its evolution. Engaging literature from philosophy, neuroscience, and retrieval then combined with deep interviews of successful lawyers to render a thick, biographical model of questioning.

Detecting the Presence of Disease by Unifying Two Methods of Remote Sensing.

Description: There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to skewed and unreliable data. However, when two like remote sensing mediums were used (i.e.- videography to videography and Landsat to Landsat) the results were positive and the data were reliable.

Development and Validation of an Instrument to Operationalize Information System Requirements Capabilities

Description: As a discipline, information systems (IS) has struggled with the challenge of alignment of product (primarily software and the infrastructure needed to run it) with the needs of the organization it supports. This has been characterized as the pursuit of alignment of information technology (IT) with the business or organization, which begins with the gathering of the requirements of the organization, which then guide the creation of the IS requirements, which in turn guide the creation of the IT solution itself. This research is primarily focused on developing and validating an instrument to operationalize such requirements capabilities. Requirements capabilities at the development of software or the implementation of a specific IT solution are referred to as capabilities for software requirements or more commonly systems analysis and design (SA&D) capabilities. This research describes and validates an instrument for SA&D capabilities for content validity, construct validity, internal consistency, and an exploratory factor analysis. SA&D capabilities were expected to coalesce strongly around a single dimension. Yet in validating the SA&D capabilities instrument, it became apparent that SA&D capabilities are not the unidimensional construct traditionally perceived. Instead it appears that four dimensions underlie SA&D capabilities, and these are associated with alignment maturity (governance, partnership, communications, and value). These sub factors of requirements capabilities are described in this research and represent distinct capabilities critical to the successful alignment of IT with the business.

Development of an Instrument to Measure the Level of Acceptability and Tolerability of Cyber Aggression: Mixed-Methods Research on Saudi Arabian Social Media Users

Description: Cyber aggression came about as a result of advances in information communication technology and the aggressive usage of the technology in real life. Cyber aggression can take on many forms and facets. However, the main focus of this study is cyberbullying and cyberstalking through information sharing practices that might constitute digital aggressive acts. Human aggression has been extensively investigated. Studies focusing on understanding the causes and effects that can lead to physical and digital aggression have shown the prevalence of cyber aggression in different settings. Moreover, these studies have shown strong relationship between cyber aggression and the physiological and physical trauma on both perpetrators and their victims. Nevertheless, the literature shows a lack of studies that could measure the level of acceptance and tolerance of these dangerous digital acts. This study is divided into two main stages; Stage one is a qualitative pilot study carried out to explore the concept of cyber aggression and its existence in Saudi Arabia. In-depth interviews were conducted with 14 Saudi social media users to collect understanding and meanings of cyber aggression. The researcher followed the Colaizzi’s methods to analyze the descriptive data. A proposed model was generated to describe cyber aggression in social media applications. The results showed that there is a level of acceptance to some cyber aggression acts due to a number of factors. The second stage of the study is focused on developing scales with reliable items that could determine acceptability and tolerability of cyber aggression. In this second stage, the researcher used the factors discovered during the first stage as source to create the scales’ items. The proposed methods and scales were analyzed and tested to increase reliability as indicated by the Cronbach’s Alpha value. The scales were designed to measure how acceptable and tolerable is cyber-bullying, cyber-stalking in Saudi ...

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Description: It is hypothesized that useful diagnostic information can reside in the wrong answers of multiple-choice tests, and that properly designed distractors can yield indications of misinformation and missing information in algorithmic reasoning on the part of the test taker. In addition to summarizing the literature regarding diagnostic research as opposed to scoring research, this study proposes a methodology for analyzing test results and compares the findings with those from the research of Birenbaum and Tatsuoka and others. The proposed method identifies the conditions of misinformation and missing information, and it contains a statistical compensation for careless errors. Strengths and weaknesses of the method are explored, and suggestions for further research are offered.

Diffusion across the digital divide: Assessing use of the Connecticut Digital Library (ICONN) in K-12 schools in Connecticut.

Description: State digital libraries are manifestations of the diffusion of technology that has provided both access to and delivery of digital content. Whether the content is being accessed and used equitably in K-12 schools has not been assessed. Determining patterns of the diffusion of use across socioeconomic groups in K-12 schools may help measure the success of existing efforts to provide equitable access and use of digital content, and help guide policies and implementation to more effectively address remaining disparities. This study examined use of the Connecticut Digital Library (ICONN) in K-12 schools in Connecticut by determining annual patterns of use per school/district over a four-year period, using transaction log search statistics. The data were analyzed in the paradigm that Rogers (2003) describes as the first and second dimensions of the consequences of an innovation - the overall growth and the equality of the diffusion to individuals within an intended audience --- in this case, students in K-12 schools. Data were compared by school district and the established socioeconomic District Reference Groups (DRGs) defined by the Connecticut State Board of Education. At the time of this study, ICONN used aggregate data (total searches) for K-12 schools, but did not have relevant data on diffusion within the public schools in Connecticut related to district or DRGs.

Discovering a Descriptive Taxonomy of Attributes of Exemplary School Library Websites

Description: This descriptive study examines effective online school library practice. A Delphi panel selected a sample of 10 exemplary sites and helped to create two research tools--taxonomies designed to analyze the features and characteristics of school library Websites. Using the expert-identified sites as a sample, a content analysis was conducted to systematically identify site features and characteristics. Anne Clyde's longitudinal content analysis of school library Websites was used as a baseline to examine trends in practice; in addition, the national guidelines document, Information Power: Building Partnerships for Learning, was examined to explore ways in which the traditional mission and roles of school library programs are currently translated online. Results indicated great variation in depth and coverage even among Websites considered exemplary. Sites in the sample are growing more interactive and student-centered, using blogs as supplemental communication strategies. Nevertheless, even these exemplary sites were slow to adopt the advances in technology to meet the learning needs and interests of young adult users. Ideally the study's findings will contribute to understanding of state-of-the-art and will serve to identify trends, as well as serving as a guide to practitioners in planning, developing, and maintaining school library Websites.

An E-government Readiness Model

Description: The purpose of this study is to develop an e-government readiness model and to test this model. Consistent with this model several instruments, IS assessment (ISA), IT governance (ITG), and Organization-IS alignment (IS-ALIGN) are examined for their ability to measure the readiness of one organization for e-government and to test the instruments fit in the proposed e-government model. The ISA instrument used is the result of adapting and combining the IS-SERVQUAL instrument proposed by Van Dyke, Kappelman, and Pybutok (1997), and the IS-SUCCESS instrument developed by Kappelman and Chong (2001) for the City of Denton (COD) project at UNT. The IS Success Model was first proposed by DeLone and McLean (1992), but they did not validate this model. The ITG instrument was based on the goals of the COD project for IT governance and was developed by Sanchez and Kappelman (2001) from UNT. The ISALIGN instrument was also developed by Sanchez and Kappelman (2001) for the COD project. It is an instrument based on the Malcolm Baldrige National Quality Award (MBNQA) that measures how effectively a government organization utilizes IT to support its various objectives. The EGOV instrument was adapted from the study of the Action-Audience Model developed by Koh and Balthazrd (1997) to measure how well a government organization is prepared to usher in e-government in terms of various success factors at planning, system and data levels. An on-line survey was conducted with employees of the City of Denton, Texas. An invitation letter to participate in the survey was sent to the 1100 employees of the City of Denton via email, 339 responses were received, yielding a response rate of 31%. About 168 responses were discarded because they were incomplete and had the missing values, leaving 171 usable surveys, for a usable set of responses that had a response ...

The Effect of Information Literacy Instruction on Library Anxiety Among International Students

Description: This study explored what effect information literacy instruction (ILI) may have on both a generalized anxiety state and library anxiety specifically. The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college students and is characterized by feelings of negative emotions including, ruminations, tension, fear and mental disorganization (Jiao & Onwuegbuzie, 1999a). This often occurs when a student contemplates conducting research in a library and is due to any number of perceived inabilities about using the library. In order for students to become successful in their information seeking behavior this anxiety needs to be reduced. The study used two groups of international students enrolled in the English for Speakers of other Languages (ESOL) program taking credit courses. Each student completed Bostick's Library Anxiety Scale (LAS) and Spielberger's State-Trait Anxiety Inventory (STAI) to assess anxiety level before and after treatment. Subjects were given a research assignment that required them to use library resources. Treatment: Group 1 (experimental group) attended several library instruction classes (the instruction used Kuhltau's information search process model). Group 2 (control group) was in the library working on assignment but did not receive any formal library instruction. After the treatment the researcher and ESOL program instructor(s) measured the level of anxiety between groups. ANCOVA was used to analyze Hypotheses 1 and 2, which compared pretest and posttest for each group. Research assignment grades were used to analyze Hypothesis 3 comparing outcomes among the two groups. The results of the analysis ascertained that ILI was associated with reducing state and library anxiety among international students when given an assignment using library resources.

The Effect of Media on Citizens' Fear of Crime in Turkey.

Description: This study was conducted on-site in Istanbul, Turkey, to determine the effects that mass media has on citizens' perceptions about fear of crime, in particular, and fear, in general. Specifically, the study was designed to (1) determine the tendency of citizens' media consumption, (2) determine the level of fear of crime among Turkish citizens, (3) establish the effect of media on citizens' fear of crime, and (4) determine if gender, age, educational level, neighborhood, and monthly income have an independent effect on fear of crime. To achieve this purpose, after administering a survey in Istanbul, the researcher collected appropriate data and then utilized regression analysis to examine the relationship between media variables and fear of crime. A survey consisting of three parts was administered to 545 Turkish citizens over the age of 18 who currently reside in Istanbul, Turkey. In Part I of the survey, respondents were asked to identify their trends in relation to media consumption, and in Part II respondents were asked to report their feelings about fear of crime. Finally, Part III consisted of socio-demographic characteristics including gender, age, marital status, level of education, and income. The media variables used for this study were, general TV viewing, watching crime drama, watching TV news, listening to radio news, reading newspaper news, and reading Internet news. Regarding the independent effects of socio-demographic variables on fear of crime, only gender was found to be significantly related thereby supporting the research hypothesis. From six media variables, only watching crime drama show and reading Internet news found to be related with individuals' fear of crime; however, this relation disappeared after controlling with socio-demographic variables. In addition, no cultivation effect could be found among the sub-groups of sample.

The Effect of Personality Type on the Use of Relevance Criteria for Purposes of Selecting Information Sources.

Description: Even though information scientists generally recognize that relevance judgments are multidimensional and dynamic, there is still discussion and debate regarding the degree to which certain internal (cognition, personality) and external (situation, social relationships) factors affect the use of criteria in reaching those judgments. Much of the debate centers on the relationship of those factors to the criteria and reliable methods for measuring those relationships. This study researched the use of relevance criteria to select an information source by undergraduate students whose task it is to create a course schedule for a semester. During registration periods, when creating their semester schedules, students filled out a two-part questionnaire. After completion of the questionnaire the students completed a Myers-Briggs Type Indicator instrument in order to determine their personality type. Data was analyzed using one-way ANOVAS and Chi-Square. A positive correlation exists between personality type as expressed by the MBTI and the information source selected as most important by the subject. A correlation also exists between personality type and relevance criteria use. The correlation is stronger for some criteria than for others. Therefore, one can expect personality type to have an effect on the use of relevance criteria while selecting information sources.

The Effectiveness of Using Lego Mindstorms Robotics Activities to Influence Self-regulated Learning in a University Introductory Computer Programming Course.

Description: The research described in this dissertation examines the possible link between self-regulated learning and LEGO Mindstorms robotics activities in teaching concepts in an introductory university computer programming course. The areas of student motivation, learning strategies, and mastery of course objectives are investigated. In all three cases analysis failed to reveal any statistically significant differences between the traditional control group and the experimental LEGO Mindstorms group as measured by the Motivated Strategies for Learning Questionnaire and course exams. Possible reasons for the lack of positive results include technical problems and limitations of the LEGO Mindstorms systems, limited number and availability of robots outside of class, limited amount of time during the semester for the robotics activities, and a possible difference in effectiveness based on gender. Responses to student follow-up questions, however, suggest that at least some of the students really enjoyed the LEGO activities. As with any teaching tool or activity, there are numerous ways in which LEGO Mindstorms can be incorporated into learning. This study explores whether or not LEGO Mindstorms are an effective tool for teaching introductory computer programming at the university level and how these systems can best be utilized.

The Effects of Student-Perceived Instructor Demotivating Behaviors on Doctoral Students' Information Seeking Behaviors

Description: In their studies on student motivation in th4e 1990s, Gorham & Christophel and Christophel & Gorham found that students perceived their own demotivation to be caused by instructor behaviors. While there are studies that explore the topic of student demotivation and other studies that illustrate the great influence instructors have on student information seeking behaviors, research focusing on the connection between these two concepts is almost nonexistent. Using Gorham & Christophel's concept of instructor-owned student demotivation, this mixed-methods study sought to identify which instructor behaviors doctoral computer science and information science students found demotivating and to what extent their perceptions of these demotivating instructor behaviors influenced their information seeking behaviors in a face-to-face classroom. Demographic and student-perceived demotivating instructor behavior surveys along with semi-structured interviews and follow-up questions were used to collect data. The surveys will be analyzed using descriptive statistics in Excel, and the semi-structured interviews and follow up questions were analyzed using content analysis and Colaizzi's method of phenomenological enquiry in NVivo. The findings showed that instructor demotivating behaviors not only influence student information seeking behaviors in the classroom, but they also can lead to lasting effects on the student. In addition, the participants have expectations of instructor behaviors, which come from their own experiences. These expectations also influence the level of demotivation they feel in a face-to-face classroom.

The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology

Description: The objectives of this study were (1) to identify and describe task-based documentation; (2) to identify and describe any purported changes in users attitudes when IT migration was preceded by task-based documentation; (3) to suggest implications of task-based documentation on users attitude toward IT acceptance. Questionnaires were given to 150 university students. Of these, all 150 students participated in this study. The study determined the following: (1) if favorable pre-implementation attitudes toward a new e-mail system increase, as a result of training, if users expect it to be easy to learn and use; (2) if user acceptance of an e-mail program increase as expected perceived usefulness increase as delineated by task-based documentation; (3) if task-based documentation is more effective than standard help menus while learning a new application program; and (4) if training that requires active student participation increase the acceptance of a new e-mail system. The following conclusions were reached: (1) Positive pre-implementation attitudes toward a new e-mail system are not affected by training even if the users expect it to be easy to learn and use. (2) User acceptance of an e-mail program does not increase as perceived usefulness increase when aided by task-based documentation. (3) Task-based documentation is not more effective than standard help menus when learning a new application program. (4) Training that requires active student participation does not increase the acceptance of a new e-mail system.

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal Intelligence

Description: Although dominant effects of tasks on individuals' information-seeking behavior is accepted by many scholars, a limited number of studies has been conducted to reveal the nature of the relationship between tasks and information-seeking behavior. In their studies, some earlier researchers categorized tasks according to their complexity while others did the same according to the specifications of tasks. Two of the groundbreaking researchers in this area are Katriina Byström and Kalervo Järvelin who contributed to the understanding of the relationship between task complexity and information-seeking behavior. However, their findings also need empirical support for theory growth. In response to this need, this study attempts to test Byström and Järvelin's findings through a research using different research methods and applied in a police work environment. Other than providing empirical support for theory growth, this research is also expected to contribute to the understudied area of police information-seeking behavior. Both qualitative and quantitative data were collected from the participants who came from traffic, homicide, and anti-terrorism divisions of Ankara, Eskisehir, and Kirikkale Police Departments in Turkey. The participants identified terrorism cases as the most complex cases to solve, followed by homicide and traffic accident cases. Differences in the information-seeking behavior of three groups of police officers were examined through qualitative and quantitative data analysis. Oneway ANOVA technique and post hoc comparisons were used to analyze the quantitative data. In addition to shedding light on information-seeking behavior of police officers investigating related cases in Turkey, the results provided support for Byström and Järvelin's findings. For instance, the officers investigating more complex tasks used significantly more information sources than the others, while the use of external information sources was significantly higher in more complex cases.

The Electronic Ranch: the Information Environment of Cattle Breeders

Description: The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.

An Empirical Investigation of Critical Factors that Influence Data Warehouse Implementation Success in Higher Educational Institutions

Description: Data warehousing (DW) in the last decade has become the technology of choice for building data management infrastructures to provide organizations the decision-making capabilities needed to effectively carry out its activities. Despite its phenomenal growth and importance to organizations the rate of DW implementation success has been less than stellar. Many DW implementation projects fail due to technical or organizational reasons. There has been limited research on organizational factors and their role in DW implementations. It is important to understand the role and impact of both technical but organizational factors in DW implementations and their relative importance to implementation performance. A research model was developed to test the significance of technical and organizational factors in the three phases of implementation with DW implementation performance. The independent variables were technical (data, technology, and expertise) and organizational (management, goals, users, organization). The dependent variable was performance (content, accuracy, format, ease of use, and timeliness). The data collection method was a Web based survey of DW implementers and DW users sampled (26) from a population of 108 identified DW implementations. Regression was used as the multivariate statistical technique to analyze the data. The results show that organization factors are significantly related to performance. Also, that some variables in the post-implementation phase have a significant relationship with performance. Based on the results of the tests the model was revised to reflect the relative impact of technical and organizational factors on DW performance. Results suggest that in some cases organizational factors have a significant relationship with DW implementation performance. The implications and interpretation of these results provide researchers and practitioners' insights and a new perspective in the area of DW implementations.

An Empirical Study of Quality and Satisfaction with a Focus on Creating a Parsimonious Measurement Instrument in an Information Space

Description: Student satisfaction and service quality are interrelated constructs that are associated with improving student retention. This research investigated the relationships between these constructs in the context of an institution of higher education as an information system and sought to reduce the dimensionality of what have traditionally been considered orthogonal factors of these constructs in order to produce a parsimonious model and survey instrument that may be useful in assessing and predicting overall student satisfaction and overall service quality. The methods of analysis used in this study are quantitative in nature and included the use of descriptive univariate, bivariate, and multivariate analyses; exploratory factor analysis to examine latent dimensions within the data; and multiple linear regressions to measure the predictive efficacy of combinations of variables with respect to overall student satisfaction and overall service quality. It was hypothesized that the statistical treatment of the data would show that some dimensions routinely collapse, leading to possible valuable theoretical implications.
