Understanding and improving the manufacturing and changeover process in Saudi Arabian business - a multiple case study approach

The importance of the changeover process in the manufacturing industry is becoming widely recognised. Changeover is a complete process of changing between the manufacture of one product to manufacture of an alternative product until specified production and quality rates are reached. The initiatives to improve changeover exist in industry, as better changeover process typically contribute to improved quality performance. A high-quality and reliable changeover process can be achieved through implementation of continuous or radical improvements. This research examines the changeover process of Saudi Arabian manufacturing firms because Saudi Arabia’s government is focused on the expansion of GDP and increasing the number of export manufacturing firms. Furthermore, it is encouraging foreign manufacturing firms to invest within Saudi Arabia. These initiatives, therefore, require that Saudi manufacturing businesses develop the changeover practice in order to compete in the market and achieve the government’s objectives. Therefore, the aim of this research is to discover the current status of changeover process implementation in Saudi Arabian manufacturing businesses. To achieve this aim, the main objective of this research is to develop a conceptual model to understand and examine the effectiveness of the changeover process within Saudi Arabian manufacturing firms, facilitating identification of those activities that affect the reliability and high-quality of the process. In order to provide a comprehensive understanding of this area, this research first explores the concept of quality management and its relationship to firm performance and the performance of manufacturing changeover. An extensive body of literature was reviewed on the subject of lean manufacturing and changeover practice. A research conceptual model was identified based on this review, and focus was on providing high-quality and reliable manufacturing changeover processes during set-up in a dynamic environment. Exploratory research was conducted in sample Saudi manufacturing firms to understand the features of the changeover process within the manufacturing sector, and as a basis for modifying the proposed conceptual model. Qualitative research was employed in the study with semi-structured interviews, direct observations and documentation in order to understand the real situation such as actual daily practice and current status of changeover process in the field. The research instrument, the Changeover Effectiveness Assessment Tool (CEAT) was developed to evaluate changeover practices. A pilot study was conducted by examining the CEAT, proposed for the main research. Consequently, the conceptual model was modified and CEAT was improved in response to the pilot study findings. Case studies have been conducted within eight Saudi manufacturing businesses. These case studies assessed the implementation of manufacturing changeover practice in the lighting and medical products sectors. These two sectors were selected based on their operation strategy which was batch production as well as the fact that they fulfilled the research sampling strategy. The outcomes of the research improved the conceptual model, ultimately to facilitate the firms’ adoption and rapid implementation of a high-quality and reliability changeover during the set-up process. The main finding of this research is that Quality’s factors were considering the lowest levels comparing to the other factors which are People, Process and Infrastructure. This research contributes to enable Saudi businesses to implement the changeover process by adopting the conceptual model. In addition, the guidelines for facilitating implementation were provided in this thesis. Therefore, this research provides insight to enable the Saudi manufacturing industry to be more responsive to rapidly changing customer demands.

Health care utilization behavior of elders in a multicultural urban environment

The objective of this research is to determine the influences of social, environmental, behavioral, and economic forces on the health care service utilization of four racial/ethnic groups of non-institutionalized elders in a multicultural urban environment. To address these issues this dissertation examines three intertwined themes of culture, aging, and health, using a sample of elders residing in Miami-Dade County, FL in four racial/ethnic groups: white non-Hispanic; black non-Hispanic English speakers; Cuban; and non-Cuban Hispanic. ^ The research questions were analyzed using both quantitative and qualitative data. Data for the quantitative component uses telephone survey data from the Dade County Needs Assessment. The purpose of this component is to develop a more comprehensive model of elder health care utilization behavior. The qualitative component uses data from focus groups from Dade County Needs Assessment, archival data and a literature review of previous ethnographic research. The purpose of this component is to gain a better understanding of the social construction of the terms “age”' and “aging,” as well as to place issues of health and health care in the lives of elders. ^ The findings raised several important issues. First, just because people share a common chronological age does not mean that they are the same in every other respect. Examining elders as a homogeneous group of users of formal health care services in a community is simplistic. Placing “aging” and “health” in a cultural context is important. My findings confirm that the meaning of “aging” and “old” are socially constructed. Further, the term “aging” is NOT synonymous with ill health or frailty. This was a consistent finding in both the quantitative and qualitative results. ^ While all aging individuals share a mutual orientation toward aging (i.e., biological process), they do not age the same way (i.e., social construction of “aging”). Thus, policymakers and others serving the elder population must be aware of the particular cultural context, as well as the previous life experiences of the individuals that they serve. This analysis documents the importance of culture and geographic community in understanding health care service utilization of elders. ^

Exploring the role of therapy process and outcome in interventions that target adolescent identity and intimacy

This study examined the feasibility of using a session impact measure with a sample of 24 at risk high school students participating in an intervention targeting identity and intimacy. Three therapists led 3 intervention groups with the same format. The study investigated the impact of therapy process, including Group, Facilitator, Skills, and Exploration impacts as measured by the Session Evaluation Form (SEF). The study also investigated the differential impact of session process on intervention outcome as measured by the CPSS, EPSI, RAVS, EIPQ and Youth Report Form. Analyses were conducted using descriptive statistics, frequencies, one-way analysis of variance (ANOVA), and Chi square tests. The results supported the utility of the SEF and they tentatively supported the impact of the therapist on participants' perceptions of therapeutic processes and on intervention outcome. In particular, Group 1 performed better than Group 3. This study found that the SEF is a useful session impact measure. ^

Finding fact by using fiction

This study was to explore the psychoanalytic process that writers experience when they write memoirs. With psychoanalytic theory, the findings were that when writers compose memoirs which include repressed information, the writer's word choice or word block is heavily influenced by his/her own moral code. This idea led to the assertions that first, we are fragmented because of the discordance that arises between the structures of morality and language, the latter which includes good and evil; second, when we write memoirs, we must create a fictional identity that allows the different fragments of identity to operate under the illusion of continuity that language provides; and third, the language we use may transcend our repressed information into consciousness. The conclusion was that when past immoral truths are uncovered, the various fragments with their selfish aims and the fictional identity cease to exist in the wake of being. ^

Teachers' perceptions of the national board certification process: Developing a sense of professionalism

This study describes and explains the experiences and perceptions of six public school teachers who had undergone the National Board for Professional Teaching Standards national certification process as a vehicle for promoting a teacher's sense of professionalism. Of these six participants, two achieved National Board certification, two did not achieve National Board certification, and two are awaiting results of their certification status. The study took place over a period of eleven months and focused on the participants' perceptions regarding the National Board certification process as it affected their sense of (a) efficacy and (b) professionalism. Data for this collective case study were gathered from interviews, portfolios and videotapes, and artifacts. Using case analysis, this study's participants' responses gathered through the interview process were examined. ^ The findings indicated that participants had concerns about the National Board certification process in the following areas: process, sense of efficacy, and sense of professionalism. All participants reported the process to be overwhelmingly demanding. Analysis of the data also reveals that those who were successful in achieving National Board certification had a greater sense of efficacy than those who did not. A disappointing finding was that the National Board process impacting participants' sense of professionalism could not be sustained; however, the participants in this study suggested the process was a step towards providing opportunities for collaboration, collegiality, and reflective practice. This study raises the question as to whether or not the espoused purposes of National Board certification are achieved via the certification process. ^

A case study: Perceptions of the induction process of intern principals in Broward County Public Schools

The case study is a qualitative study of the perceptions of a purposeful sample of intern principal participants in Broward County Public School's 2001-2003 principal leadership induction program through survey, interview and document analysis of their experiences concerning their success or failure in achieving the position of principal. The study focused on constructs of professional and organizational socialization and instructional leadership that research suggests are vital and integrated components of the effective development of aspiring instructional leaders. ^ The findings revealed that purposeful mentoring, a variety of site placement, hands on practical experiences, in addition to the quality of experience measured by the number of years prior experience are positively reported to affect the degrees of success perceived by intern principals. The study validated the interrelatedness of the three constructs professional and organizational socialization and instructional leadership as components that are realized in the development process through formal and informal characteristics of socialization. The data gathered would be of benefit to principal leadership program designers to assist in their understanding of participants' successes and failures that influence individual needs based on their experience as perceived by this group. ^ Implications for further study are the need for better understanding of leadership development, continued reinforcement of best practices such as mentoring, site shadowing and coaching, clarification of the administrator's role, data analysis, curriculum implementation and student achievement. Organizations need to implement a common set of expectations, reasoning, attitudes, and understanding of purpose that guide behaviors. Recommendations are to design leadership induction programs to meet individual strengths and weaknesses not a one-size-fits-all program including a constructive and prescriptive two-way feedback system, select and assign mentors based on their expertise and candidate needs, varied site placements, develop skills to build collaborative relationships, and a standards based monitoring and assessment system to document program mastery and completion. ^

An examination of Lotka's law in the field of Library and Information Studies

The purpose of this study was to test Lotka’s law of scientific publication productivity using the methodology outlined by Pao (1985), in the field of Library and Information Studies (LIS). Lotka’s law has been sporadically tested in the field over the past 30+ years, but the results of these studies are inconclusive due to the varying methods employed by the researchers. ^ A data set of 1,856 citations that were found using the ISI Web of Knowledge databases were studied. The values of n and c were calculated to be 2.1 and 0.6418 (64.18%) respectively. The Kolmogorov-Smirnov (K-S) one sample goodness-of-fit test was conducted at the 0.10 level of significance. The Dmax value is 0.022758 and the calculated critical value is 0.026562. It was determined that the null hypothesis stating that there is no difference in the observed distribution of publications and the distribution obtained using Lotka’s and Pao’s procedure could not be rejected. ^ This study finds that literature in the field of Library and Information Studies does conform to Lotka’s law with reliable results. As result, Lotka’s law can be used in LIS as a standardized means of measuring author publication productivity which will lead to findings that are comparable on many levels (e.g., department, institution, national). Lotka’s law can be employed as an empirically proven analytical tool to establish publication productivity benchmarks for faculty and faculty librarians. Recommendations for further study include (a) exploring the characteristics of the high and low producers; (b) finding a way to successfully account for collaborative contributions in the formula; and, (c) a detailed study of institutional policies concerning publication productivity and its impact on the appointment, tenure and promotion process of academic librarians. ^

Evaluating a Cuisine: Six Criteria

Defining what makes up "a cuisine" involves finding a way to evaluate what makes it "distinctly unique and meritable." In this first of a two-part series, the author develops six criteria which can be used in such an evaluative process.

Four essays of environmental risk-mitigation

Expected damages of environmental risks depend both on their intensities and probabilities. There is very little control over probabilities of climate related disasters such as hurricanes. Therefore, researchers of social science are interested identifying preparation and mitigation measures that build human resilience to disasters and avoid serious loss. Conversely, environmental degradation, which is a process through which the natural environment is compromised in some way, has been accelerated by human activities. As scientists are finding effective ways on how to prevent and reduce pollution, the society often fails to adopt these effective preventive methods. Researchers of psychological and contextual characterization offer specific lessons for policy interventions that encourage human efforts to reduce pollution. This dissertation addresses four discussions of effective policy regimes encouraging pro-environmental preference in consumption and production, and promoting risk mitigation behavior in the face of natural hazards. The first essay describes how the speed of adoption of environment friendly technologies is driven largely by consumers' preferences and their learning dynamics rather than producers' choice. The second essay is an empirical analysis of a choice experiment to understand preferences for energy efficient investments. The empirical analysis suggests that subjects tend to increase energy efficient investment when they pay a pollution tax proportional to the total expenditure on energy consumption. However, investments in energy efficiency seem to be crowded out when subjects have the option to buy health insurance to cover pollution related health risks. In context of hurricane risk mitigation and in evidence of recently adopted My Safe Florida Home (MSFH) program by the State of Florida, the third essay shows that households with home insurance, prior experience with damages, and with a higher sense of vulnerability to be affected by hurricanes are more likely to allow home inspection to seek mitigation information. The fourth essay evaluates the impact of utility disruption on household well being based on the responses of a household-level phone survey in the wake of hurricane Wilma. Findings highlight the need for significant investment to enhance the capacity of rapid utility restoration after a hurricane event in the context of South Florida.

Localização de robôs móveis em ambientes fechados utilizando câmeras montadas no teto

The localization of mobile robots in indoor environments finds lots of problems such as accumulated errors and the constant changes that occur at these places. A technique called global vision intends to localize robots using images acquired by cameras placed in such a way that covers the place where the robots movement takes place. Localization is obtained by marks put on top of the robot. Algorithms applied to the images search for the mark on top of the robot and by finding the mark they are able to get the position and orientation of the robot. Such techniques used to face some difficulties related with the hardware capacity, fact that limited their execution in real time. However, the technological advances of the last years changed that situation and enabling the development and execution of such algorithms in plain capacity. The proposal specified here intends to develop a mobile robot localization system at indoor environments using a technique called global vision to track the robot and acquire the images, all in real time, intending to improve the robot localization process inside the environment. Being a localization method that takes just actual information in its calculations, the robot localization using images fit into the needs of this kind of place. Besides, it enables more accurate results and in real time, what is exactly the museum application needs.

The transition experience for registered nurses new to case management in the community

Case management is increasingly being used within today‟s healthcare system in an effort to reduce healthcare costs while meeting the complex needs of populations within the community. Registered nurses (RNs) are often recruited for the role of case managers in the community because of their specific skill set and ability to navigate the healthcare system. There is a vast amount of literature related to the client and system benefits of case management, the roles and responsibilities of RN case managers, and job satisfaction among RN case managers. However, there is a literature gap noted in relation to the transition experience for RNs new to case management in the community setting. This research study used grounded theory methodology, guided by Glaser and Strauss (1967) to explore the process of RNs transitioning to case management in the community setting. Eleven RNs new to case management in the community were interviewed using semi-structured interviews. Data analysis was carried out using the constant comparative method. Three stages of adjusting to case management in the community were identified: slugging it out, seeing the job as it is, and finding the way. By gaining an understanding of this transition experience, recommendations for nursing practice and administration, education, and research that are based on the evidence from this study can be implemented to improve the transition experience for RNs new to case management in the community setting

A escrita da escrita em (d)enunciação no espaço sócio-escolar: um espaço (em vão) para a (cri)atividade escrita

This thesis is a writing of (d)enunciation because it reveals the language experiencies of those individuals who take, in social school space, the social role of the teacher and of the student, for some reason, they feel restrained by a demand which prevents them of teaching and learning how to write – and, even, their own writing. On this basis, we consider some questions concerning Benveniste‘s theory of enunciation and the teaching and learning process in Portuguese from the triad among teacher – teaching of writing/ knowledge – student, making this theoretical area closer to the pedagogical one. We support in the working hypothesis that is based on the position of the loosening of this triad has its effects in the process of intervention-interference to the point where it does not leave a scar which can remain working on productive effects on the student‘s writing. As a consequence, we show two findings which allow us to think the teaching of writing in Portuguese is a space for writing creativity in such a way it reveals itself as a sine qua non condition for the institutionalized and subjective writing. The first finding is that taking genre as a model has some implications in the teaching and learning process of writing according to the instructions of the official documents. The second finding, as a result of the first one, is the assumption that genre is at the same time a model and a transgression and taking it as a (ex)sample opens space for writing creativity which ―is a transposition of the interior language‖ (BENVENISTE, 2014 [1968-1969], p. 132) in a way this creativity makes it intelligible and highlights what is a model (interactiveness) and a transgression (inventiveness). From such findings, we organize our heterogeneous corpus according to these procedures: recording the classes in audio; recording the interviews we made with teachers and students in audio; and constituting an archive with the students‘ writing production. From this corpus, we analyzed the (d)enunciative mo(ve)ments in the teacher – teaching of writing/ knowledge – student triad and the history of (d)enunciations, of language experiences. Besides, we analyzed the teacher‘s discourse in relation to the way he plans his classes based on the knowledge that must be taught and his own way of managing this knowledge in order to understand his interference in his students‘ writings. Our analyses (re)affirm that when the loosening of the triad happens, the students become lost, what makes them unable of working upon their own writing epilinguisticaly. Because of it, schools have lost their specificity as a place for teaching students how to read and write as they open space for training, only. On this basis, we consider that the effect of such a loosening generates complaints and denunciations. Therefore, based on such (d)enunciations, we present the Primary sketches of a proposition for intervention-interference in teaching how to write and we aim at introducing much knowledge to teachers and students in order to allow them to think about possible ways out.
