This study examined the attitudes of employees of the United States Department of Agriculture's Animal Damage Control (ADC) Program. This research examined ADC employees' attitudes about wildlife, the ADC program and ADC employment, wildlife damage management methods, euthanasia and the killing process, and the role of various public and private groups on ADC policy. This study also applied the theory of organizational capture to the ADC program to test its utility in explaining the attitudes and behaviors of employees. Results were based on a survey of ADC employees conducted in January 1995. Survey responses were analyzed to explore associations between employee attitudes and job type or time of service at ADC. Job type was found to be a better indicator of employee attitudes than time of service. Field and management employees tended to have more positive views of ADC and ADC employment compared with research employees. Respondents with different job types perceived different levels of effectiveness and humaneness for wildlife control methods. In general, field employees viewed lethal techniques as more effective and humane than research employees. Similarly, research employees reported nonlethal techniques to be more effective and humane than field employees. Finally, research employees felt that outside interest groups should have more influence on ADC practices than field and management employees felt they should. ADC employees were found to have some characteristics indicative of organizational capture. They had a homogeneous client base, and were resistant to reaching out to nontraditional clients in the face of opposition from traditional clients. However, they were not deflected from the ADC mission. Because respondents indicated conformity to the ADC mission, ADC was found to be at most variably captured by its traditional farming and ranching clientele.

The llama, a potential socioeconomic resource in the Bolivian highlands, faces serious nutritional deficiencies during the gestational and postpartum stages that negatively affect production. This study was conducted at the Tika Huta Experimental Center in the Llachu community of the Oruro prefecture. Our objectives were to determine metabolite concentration in blood plasma as well as live weight performance of pregnant and postpartum female llamas. Adult and juvenile llamas were fed diets of either plain natural grass or natural grass combined with 0.4 kg of barley hay. In addition, we determined metabolite concentrations in blood plasma and live weight performance of newborns until three months of age. Ten newborn llamas and nine pregnant adult llamas were used. We collected 133 blood plasma samples from mothers and 57 blood plasma samples from newborns. The samples were sent to laboratories at Brigham Young University for analysis. Results showed the following metabolite concentrations in pregnant llamas: 7.23 ± 1.80 g/dl total proteins, 36.31 ± 1.32 mg/dl urea, 84.72 ± 3.58 mg/dl triglycerides, 55.89 ± 2.32 mg/dl cholesterol, and 7.11 ± 1.34 mg/dl creatinine. In newborn llamas, blood plasma metabolite concentrations were as follows: 7.20 ± 1.54 g/dl total proteins, 48.41 ± 1.30 mg/dl urea, 103.25 ± 2.60 mg/dl triglycerides, 89.09 ± 3.30 mg/dl cholesterol, and 2.39 ± 0.33 mg/dl creatinine. The average live weights were 76.82 ± 8.57 kg and 15.95 ± 2.47 kg for mothers and newborns, respectively. Animals fed diets of natural grass and barley hay yielded results with significant differences. It is recommended that llama diets be supplemented with barley hay during the first two months of gestation, the last third of gestation, and postpartum.

This study was carried out in the Azafranal community of the Desaguadero municipality, which is in the Ingavi Province of the Department of La Paz. It was conducted at an altitude of 3350 meters above sea level at 16°20’00” south latitude and 69°00’00” west longitude. The study went from December 20, 2003 to June 20, 2004. Our objective was to evaluate hair production in angora rabbits (Oryctolagus cuniculus) fed with three different rations of reed. The experimental trial was done at the Angorita farm over a 135 day period that was divided into three smaller periods of 45 days. The experiment was done via a completely randomized block design. The means from each treatment (A, B, C, and D) were analyzed by a Duncan test with a level of 95% confidence. The population consisted of 16 male and 16 female English angora rabbits between 90 and 98 days of age. These were divided into four groups of eight individuals. Each group was then subjected to one of four treatments: 1) ration A with 40% reed content, 2) ration B with 30% reed content, 3) ration C with 20% reed content, and 4) ration D as a control with 0% reed content. The variables measured and studied were: hair weight (g), hair diameter (µ), hair length (cm), and length of a lock of hair (cm). The results reflect a positive effect on hair diameter with rations C and A, which had average diameters of 9.48 µ and 9.64 µ respectively. Furthermore, with respect to hair length, ration A had an average of 4.87 cm and ration C had an average of 4.68 cm. Lastly, with respect to length of a lock of hair, ration A had an average of 4.74 cm and ration B had an average of 4.52 cm (P<0.05). Hair weight did not turn out to be significant, coming in with an average of 61.03 g (P>0.05).

This research was completed in Letanías, Viacha, La Paz, Bolivia, to determine the metabolic profile in blood plasma (total protein, glucose, urea, albumin, total lipids, creatinine, triglycerides, and cholesterol concentrations), live weight gain, and Nitrogen balance in adult llamas fed with 4 rations of barley and quinoa residue. Eight adult (4-5 year old) Q’ara type llamas were used in this study. Study llamas were trained to stay in metabolic cages with feces collection harnesses. Llamas were given one of the following feed rations: ration A (20% quinoa residue, 80% barley), ration B (40% quinoa residue, 60% barley), ration C (60% quinoa residue, 40% barley), and ration D (80% quinoa residue 20% barley). The results were protein concentration 7.44±0.39 g/dl; albumin 4.66±0.80 mg/dl; urea 13.87±3.70 mg/dl; creatinine 1.65±0.19 mg/dl; glucose 127.67±50.32 mg/dl; total lipids 318.2±144.14 mg/dl; triglycerides 39.35±13.49 mg/dl; cholesterol 53.85±13.53 mg/dl. Live weight gain was -0.0094±1.44 kg. Nitrogen balance was 0.610±0.0868 g/kg. According to the results of this research, metabolites in blood plasma are higher when compared to other research. Gain in body weight was negative in rations A and D and positive in rations B and C. This is attributed to a better equilibrium among energy levels and protein in these last rations. The nitrogen balance was positive for all four rations due to an adequate source of protein in the feed.

This investigation was performed in the Altiplano Altoandino sub-humid region in the Ulla Ulla district, Pelechuco township, Franz Tomayo province, department of La Paz, Bolivia. The objective of this study was to quantify and compare the presence of Brucellosis in male and female alpacas (Lama pacos) at ages 2, 3, 4, 5, 6, and 7 years. Blood samples were taken from the jugular vein of 500 alpacas from the Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla communities. The serum from each sample was separated and a serological diagnosis was performed by rapid agglutination with Rose Bengal chemical stain. In the Ulla Ulla district, 11.0% of alpacas were suspected of being infected. Of that 11.0%, 9.6% represented female alpacas while the remaining 1.4% represented male alpacas. By community, the overall results were 0.6%, 0.2%, 7.4%, and 2.8% for Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla respectively. With regards to gender in each community, 1.4%, 1.6%, 13.3%, and 11.1% of female alpacas and 2.7%, 0.0%, 1.2%, and 1.9 % of male alpacas were suspected of being infected in Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla, respectively. According to age, 0.8%, 2.6%, 3.8%, 2.0%, 11.8%, and 0.0% were suspected of Brucellosis in alpacas 2, 3, 4, 5, 6, and 7 years old, respectively in the Ulla Ulla district. The analysis of variance among the results does not present significant differences (p ≥ 0.05), failing to reject the given hypothesis. The final prevalence point found in the Ulla Ulla district was 11.0%. It was concluded that the prevalence of suspected cases of Brucellosis in alpacas is a consequence of the antigenic characteristics of each biotype. Furthermore, the results affirm that the poor management of livestock and livestock health lead to significant problems with alpaca health. It is therefore necessary to implement control strategies as well as disease monitoring in communities by following a detailed program of diagnostic tests for Brucellosis. Also, non-infected flocks must be protected against infection.

When Department of Defense (DoD) personnel receive orders to relocate to a new duty installation, nearly one third abandon their companion animals, which negatively affects the local shelters' costs, personnel, and capabilities to provide quality care for shelter animals. There is a lack of research on relevant policies among local government policy makers, installation commanders, directors of animal shelters, and animal rights advocates about the abandonment of companion animals by DoD personnel. The purpose of this qualitative descriptive case study was to investigate the relationship between the influx of abandoned DoD companion animals and the management and logistical (including financial) operations of 2 publicly funded animal shelters near a Midwest DoD installation. The theoretical framework was Merton's theory of unintended consequences. Data were collected through interviews with 2 shelter directors, 10 surveys completed by shelter personnel, and a review of the shelters' logistical and financial documents spanning fiscal years 2013 - 2014. Data were analyzed after coding for themes and patterns. According to study findings, the abandonment of companion animals by DoD personnel has a negative impact on the shelters' finances, shelter personnel workload and stress, and the quality of life for incoming animals as well as those already in the shelters. The implications for positive social change are to inform policy makers of the importance of implementing policies to keep DoD companion animals with families, thereby easing transitions for those at risk, which helps to maintain the financial solvency of animal shelters, reduce stress for shelter personnel, and help companion animals to adjust as they are adopted into new homes.

Llamas have provided, and continue to provide, fiber, meat, skins, fertilizer and transport for the Andean people. In addition, they are part of the traditional and religious culture of the Aymara and the Quechua. Both are currently unaware of the productive qualities of llamas, especially those related to meat production, which is the principle product responsible for generating greater income for farmers. For this reason, 554 llamas were evaluated from a total of 3,693 in 2005. The llamas came from T’olar and Pajonal grasslands in the Santiago de Machaca region of La Paz, Bolivia and represented males and females from four age categories (newborn, 1-2 years, juvenile, and adult). They were evaluated with the objective of determining the zoometric measurements of llamas fed on T’olar and Pajonal grasses. Evaluations were categorized according to gender and age group, while also applying descriptive statistics of zoometric measurements of llama anatomy including the head, neck, thorax, and abdomen regions, as well as height, weight, and fur thickness. The Pv measurement for T’olar fed llamas (64.4 kg) was higher than that of the Pajonal fed llamas (59.9 kg). With respect to gender, females (67.1 kg) were larger than males (53.0 kg). Adults were the largest age group (89.7 kg), followed by juveniles (85.9 kg), 1-2 years (58.7 kg) and newborns (34.1 kg). The T’olar llamas achieved better results than the Pajonal llamas. Furthermore, females were superior to males, most likely due to the large number of females as compared to males in the llamas. Zoometric measurements increased with age, generally reaching a statistically significant margin (P<0.01) between age groups. Growth was greatest between the newborn and juvenile groups but it ultimately slowed down afterwards.

The Vespidae family (order Hymenoptera) is comprised of 4500 species of wasps in 268 genera and 7 subfamilies. These wasps prey upon a wide range of insects, including Lepidopteran caterpillars. Because of their low prey specificity, the use of Vespid wasps in biological control programs is limited. However, in their natural habitat, they play a role in controlling populations of some pest species. This study was conducted in six different communities in the department of La Paz within the municipalities of Coroico and Coripata. Three ecological niches were selected in each community: 1) the forest, 2) the edge of the forest and 3) a crop producing area. In each study unit, three Malaise traps were set up on a 14 day collection cycle from June to December 2007. Over the six month study period, we collected a total of 772 individuals and identified 36 different morphospecies from the six communities. The most abundant genera collected were Protopolybia sp., Mischocyttarus sp., and an unidentified genus (morphospecies #2) which had the greatest abundance of individuals in all of the different ecological niches. The niche factor did not have a significant influence on species diversity in the three ecological niches studied. Generally, this group of wasps is found in all three ecological niches.

The success of a course offered by a university and the effectiveness of the instructors have commonly been measured by means of student evaluations. The feedback generated is typically used to identify instructors who need additional training, courses that need to be restructured or the need for financial rewards for those who excel. The principal objective of educating students is, knowledge, training and skills they can use and apply after graduating, regardless of the field of study. The perception of the Alumni about the extent of learning and the usefulness of the knowledge is a key measure for universities to assess their success. A service guarantee is defined as a formal promise made to customers about the service they will receive or it is a written promise made by the company through advertising or company literature that it will provide compensation if promises are broken. In order to ensure customer satisfaction in a service offering, the quality of service performance needs to be guaranteed. Many service industries promise a level of service performance, with or without conditions attached. Customer value is a complex concept as it is often interpreted with various meanings depending on the point of view adopted. A definition of customer value is the perceived value that the customer gains when purchasing a product or receiving a service. However, customer value can be used in a variety of contexts. The purpose of this research study is to measure the perception and satisfaction of Alumni of the Department of Computing Sciences and identify areas for improvement by performing a systematic analysis of the determinants of satisfaction. This research is an exploratory, quantitative study consisting of literature- and case-study components used to test proposed hypotheses. The literature study was performed on secondary sources to establish the key concepts related to the topics of Service Guarantee and Marketing, Stakeholder Theory, Customer-perceived Value and Alumni Perceptions. The empirical study consisted of surveys (questionnaires) completed by Alumni of the Department of Computing Sciences. The questionnaire used in this research consisted of questions regarding demographic data and questions regarding perceived perception of the Department of Computing Sciences and influencing factors. Descriptive statistics were used to summarise the data into a more compact form which could simplify the identification of patterns in the data. Inferential statistics were used to verify if conclusions made from the sample data could be inferred onto a larger population. Recommended university and teaching practices based on the statistical analysis of the survey results were identified. A model identified the following factors as having an influence on Alumni Satisfaction with the NMMU Department of Computing Sciences: Customer Satisfaction, Course Contents, Modern Technologies, Academic Staff, Admin. Staff, Departments, University Atmosphere and Perceived Value. The importance of each factor was identified to understand how to improve the Alumni perception. According to the inferential ranking of Alumni Satisfaction that ranks the factors on the average mean values, a factor that should be improved upon is the Alumni Network. Recommended improvements were suggested for the Department of Computing Sciences based on the statistical analysis of the survey results. Two sub-groups were defined by different levels of education and they were found to have different perceptions of the factors that were measured. It was shown that there are small and medium significant differences in only two of the factors of the proposed Alumni satisfaction model, distinguising through different levels of education. The Alumni Satisfaction model developed in this study specified the factors that influence Alumni Satisfaction with the Deptarment of Computing Sciences and the effect that each of these factors has on that satisfaction.

The purpose of this study was to examine theories of organizational culture typically applied to the university level of organization and their applicability to the academic department. Chaffee and Tierney's (1988) theory of organizational culture, dimensions of culture, and leadership strategies became the basis for a qualitative case study of a Department of Biological Sciences in a metropolitan university.;Interviews of current faculty members, current and former deans, and other administrators were conducted. Observations were made of faculty meetings and retreats and of departmental governance committee meetings. Extensive review of documents and correspondence covering more that twenty years provided additional data.;Interview and observation transcripts and documents were analyzed in terms of Chaffee and Tierney's (1988) concepts of the structural, environmental, and values dimensions of the department. Linear, adaptive, and interpretive strategies of faculty members and the department chair were identified.;The department was found to have what Clark (1972) refers to as strong organizational saga, or a sense of unique accomplishment which serves to maintain and perpetuate the integrity of the culture. Central to the value system of the Department of Biological Sciences is the shared sense that the department is unique in the degree to which faculty members work together cooperatively for the good of the department. These strong values were rooted in an earlier era when the department was experiencing growth and development of its research programs under adverse circumstances.;The primary usefulness of the results of this study go far beyond the particular findings for this individual academic department. Most important is the demonstration of the value of using this method of organizational analysis to understand the role of culture in shaping and perpetuating the organization. Administrators, department chairs, and faculty members can enhance their understanding of the departmental organization by applying concepts of organizational culture.;Further study and analysis are needed to evaluate disciplinary and institutional similarities and differences in departmental culture and to expand the existing theory to accommodate the variety of academic departments in colleges and universities.

As the new millennium begins, networked information technology systems are progressively more essential to the success of an organization (Turban, McLean & Wetherbe, 2001). With the steady growth of computer power and ever-increasing access to communications networks, digital information is an increasingly important resource (Li, Wang, & Wiederhold, 2000). As the information technology has changed, so too has the implementation of that technology changed. The changing digital information era presents significant challenges to organizations because there is a growing interdependence between organizational management methods and procedures on one side and information technology and communications on the other (Laudon & Laudon, 2001). A change in anyone of the components often requires changes in other components (Laudon & Laudon, 2001). The changes and challenges to organizations brought about by information technology apply to governmental entities such as local police departments. The widespread use of computers and the rapidly developing technology of communications have combined to dramatically increase the volume and complexity of digital information resources available for criminal investigations and criminal-related research (Freeh, 2000). Following the September 11, 2001 terrorist attacks on the United States, emphasis has been placed on using networked information resources as a means to identify people and determine associated criminal histories. This single case study investigated the implementation of a networked information technology system operating in the real-world setting of a local police department. The objective of this study was to examine information technology successfully implemented as an investigative resource for law enforcers. This included reviewing criminal justice information resources that became available between 1999 and 2001, and reviewing the impact of the September 11, 2001 events on information technology implementation for criminal investigation and research. It also includes the examination of theories taken from recent literature from the period 1998 to 2002, regarding methods of successful system implementation. The major contribution of the study is that it provides a broad comprehensive analysis of a mixed mode wireless and wireline networked information technology system implemented to support criminal investigations and criminal-related research. The study presents a timely model of technology implementation, following the September 11, 2001 terrorist attacks and passage of the USA PATRIOT Act. Other police departments and criminal justice agencies can use the study model to implement similar networked information systems. Results of the study indicated that the implementation of the information technology was successful because the implementation followed accepted theories in recent literature, and has had a consistent positive impact on the Melbourne Police Department. Positive and significant productivity results were achieved via the implementation processes utilized by the police department. Lastly, the study provides recommendations to local police departments and criminal justice agencies on whether continued implementation of information technology developed under current theories is warranted.

As emergency department (ED) waiting times and volumes increase, substantial numbers of patients LWBS (leave after registration but prior to physician assessment). The objective of this study was to identify ED conditions reflecting patient input, throughput and output associated with the number of patients who LWBS in a pediatric setting. Multivariate analysis was used to examine the impact of variables describing the timing of patient arrival and ED conditions including patient acuity, volume and waiting times on the number of patients who LWBS. During the study period there were 138,361 patient visits; 11,055 (7.99%) of patients LWBS. The throughput variables, time from triage to physician assessment (rate ratio 2.11 (95% CI 2.01-2.21)) and time from registration to triage (rate ratio 1.55 (95% CI 1.25 - 1.90)) had the largest impact on the number of patients who LWBS. Interventions designed to decrease the number of patients who LWBS should focus on improving ED throughput.
Avec l'augmentation du débit et du temps d'attente dans les services des urgences, un nombre élevé de patients ayant rempli les formulaires d'accueil quittent avant d'avoir été vus par un médecin. Cette étude avait pour but de déterminer les conditions du service des urgences reflétant l'inscription, le temps de prise en charge ainsi que le débit de patients, et ayant un lien avec le nombre de personnes qui, dans un milieu pédiatrique, quittent avant d'avoir vu un médecin. Une analyse multivariée a été utilisée afin d'examiner l'effet de variables décrivant le moment de l'arrivée du patient et les conditions qui prévalent au service des urgences (y compris l'acuité des patients, le volume de patients et le délai d'attente), sur le nombre de personnes qui quittent sans avoir été examinés. Un total de 138,361 patients se sont présentés à l'urgence au cours de l'étude et 11,055 (7,99%) ont quitté avant d'avoir vu un médecin. Les résultats de l'étude révèlent que les variables liées au temps de prise en charge, soit le délai entre le moment du triage et l'examen du médecin (ratio des taux = 2,11; intervalle de confiance [IC] de 95% : 2,01 - 2,21) et le délai entre l'inscription et le triage (ratio des taux = 1,55; IC de 95% : 1,25 - 1,90) exercent la plus grande influence sur le nombre de patients quittant avant d'avoir été vus par un médecin. Les interventions visant à réduire le nombre de départs prématurés devraient être orientées en vue d'améliorer le temps de prise en charge dans les services d'urgence.

Background: It is important to understand Canadians' expectations of health care services and the costs of delivering care in the Emergency Department (ED) in order to continue to provide health care in a sustainable manner. Objectives: To examine the reasons patients present to the ED, and to conduct a cost analysis to compare the costs of seeking care in the ED versus a primary care setting. Methodology: We surveyed patients (n=606) triaged to the cubicles of the ED of The Ottawa Hospital, Civic Campus. The survey asked about their perceived urgency level and their patterns of health service use. Patient surveys were accompanied by physician surveys to assess each patient's level of urgency from a medical perspective. We performed bivariate analysis and logistic regression on survey variables of interest. We also conducted a cost analysis to determine the costs of providing non-urgent care in the ED. Results: Both a presenting symptom of a musculoskeletal injury (OR=2.93, CI 1.42-6.04) and having heard of TeleHealth Ontario (OR=2.08, CI1.08-4.03) were significantly associated with non-urgent ED use from the patient perspective. We also found that non-urgent ED visits cost an average of $248.75, which is significantly more costly than a primary care visit. Implications: Our results provide insights regarding patient factors influencing ED use and relative costs of non-urgent ED visits versus outpatient family doctor visits. However, additional work may be required to identify non-medical factors influencing patient motivations for seeking care in the ED.

Diabetes is one of the most prevalent diseases in America, and the associated costs place a heavy burden on our health care system. This study was undertaken to provide information on emergency service utilization and hospitalization among people with diabetes in the United States. The hypotheses were that adults with diabetes visit the emergency department (ED) more than those without diabetes, that persons with diabetes who present in the ED are hospitalized more than those without diabetes and that more patients with diabetes present in the ED within 1 week of hospital discharge than those without diabetes. To test these hypotheses, secondary data from the 2010 National Hospital Ambulatory Medical Care Survey was analyzed. The results indicate that adults with diabetes did utilize the ED more than those without diabetes, and that patients with diabetes were admitted to the hospital through the ED more than those without diabetes. Furthermore, persons with diabetes presented within 1 week of hospital discharge more than those without diabetes.

The purpose of this study was to analyze the factors associated with higher Emergency Department (ED) visits in the United States. Higher ED utilization contributes in a major way to costs in the healthcare industry. Unnecessary utilization of emergency department causes medication errors, poor patient satisfaction, lower quality and higher cost. This study analyzed the data from National Hospital Ambulatory Medical Care Survey (NHAMCS) collected in 2010, which involved a sample size of 34,936 ED visits nationwide. The variables in this study included age, ethnicity, type of coverage and gender differences. The result showed that Medicaid population has a higher number of ED visits than other types of insurance coverage; white population shows maximum ED visits than other race types; males visits ED more than females and infants has higher ED rate than other age groups. More research is needed to develop health policies to limit the non-urgent ED visits.

Regular use of the emergency department is associated with a patient's inability to identify a regular primary care physician. Continuity of the physician-patient relationship is largely determined by patient satisfaction, which in turn is influenced by the physician's communication and interpersonal skills. The objective of this study was to estimate the relationship between the communication competency of newly licensed family physicians and the ambulatory health care utilization behaviour of their regular emergency department users. It was hypothesized that physicians with higher levels of competency in patient communication would be the providers of a greater proportion of their patients' ambulatory care than physicians with poorer communication abilities. Consequently, these patients would rely on the emergency department for a smaller proportion of their ambulatory care than patients of physicians with lower levels of communication competency.
In total, 474 newly licensed family physicians and 42 113 regular ED user patients were included in the study population. Analysis was conducted at the level of the physician and patients were attributed to the practice populations of the first study physician they saw. (Abstract shortened by UMI.)

The purpose of this project was to demonstrate whether a multifaceted quality improvement intervention program would improve hand hygiene compliance of healthcare providers (HCPs) in the Emergency Department (ED). A descriptive design with an observational approach was used with a convenience sample of ED healthcare personnel at a large, 500 bed community hospital. Seven hundred and fifty-eight hand hygiene compliance direct observations were collected during 3 time periods (baseline, pre-intervention and post-intervention observation periods). Descriptive and inferential statistics were used to analyze differences in hand hygiene compliance across the observation periods and by HCP job category.

The results indicated a statistically significant increase in hand hygiene compliance among all groups combined after a multifaceted intervention program was implemented. Efforts to change behavior, lifestyle and the environment must be varied and the target audience must be involved to be effective. This model can be applied to HCPs in other healthcare settings to improve compliance with hand hygiene, a fundamental infection prevention practice to prevent healthcare acquired infections.

Prediction of sales is an important field in the food industry and dueto new technologies it has recently gained alot of attention in order toimprove business operations and profitability. However, historicallythe industry has relied on traditional statistical models but in recentyears more advanced machine learning methods has gained traction.This study aims to compare three machine learning methods forsales prediction in the food industry: Multilayer Perceptron (MLP),Support Vector Machine (SVM) and Radial Basis Function Network(RBFN). The methods were compared in terms of their prediction accu-racy on daily sales in a food store department. The performance of themodels was determined using the performance measures: Mean Aver-age Percentage Error (MAPE) and Root Mean Squared Error (RMSE).The results show that the SVM performed lower error measuresthan the other two methods. The repeated measure analysis of vari-ance (rANOVA) was used in order to determine if there was a differ-ence between the methods. The test indicated a statistical significantdifference between the afformentioned methods.
Försäljningsprediktion är ett viktigt område inom livsmedelsindustrin och tack vare nya teknologier har området nyligen fått stor uppmärksamhet i syfte att förbättra affärsverksamheten och lönsamheten i en mataffär. Historiskt sett har livsmedelsindustrin dock använt sig av traditionella statistiska modeller men under senare år har mer avancerade maskininlärningsmetoder vunnit mark. Denna studie ämnar att jämföra tre maskininlärningsmetoder för försäljningsprognostisering inom livsmedelsindustrin: Multilayer Perceptron med hjälp av backpropagation (MLP), Support Vector Machine (SVM) och Radial Basis Function Network. Metoderna jämfördes med avseende på deras prediktionsträffsäkerhet på daglig försäljning i en butiksavdelning och mättes med hjälp av mätningsvärktygen: medelprocentfelet (MAPE) och rotmedelfelet (RMSE). Resultaten visar att SVM presterade lägre prediktionsfel än de andra två metoderna. Upprepad variansanalys (rANOVA) användes för att avgöra om det förelåg någon skillnad mellan metoderna. Testet indikerade en statistiskt signifikant skillnad mellan metoderna.

Introduction. Optimal management of paroxysmal atrial fibrillation (PAF), a common presenting complaint in emergency departments (EDs), remains undetermined. Methods. Six month prospective observational study at three EDs. Patients had clinically stable PAF for less than 48 hours. Conservative (rate control) and aggressive (pharmacologic and/or electrical cardioversion) treatment were analyzed. Results. 169 patients were analyzed, 32 treated conservatively and 137 aggressively. 83.9% of aggressively treated patients converted in the ED, 8.0% were admitted, and 52.3% stayed in sinus rhythm for four weeks. The corresponding proportions for conservative treatment were 34.4%, 37.5%, and 30.0%. There were 15 ED complications (2 rate control, 4 pharmacologic, and 9 electrical), two required admission (one pharmacologic and one electrical). No thromboembolism occurred by four-week follow-up. Conclusions. The results of this study---the first prospective study of ED treatment of PAF---will be used to plan a randomized controlled trial which will compare the two treatments.

Анотація:

Emergency department (ED) overcrowding is a widespread and multifaceted problem caused by many factors including overutilization of the ED by non-emergency patients and a decreasing number of available ED beds nationwide. The flow of patients through the ED is known as throughput process, and many interventions to improve the efficiency have been described in the literature including sorting patients by acuity or condition, placing providers in the triage area, using a flow expeditor role and various technology applications.

This retrospective, comparative study assessed the implementation of an experienced registered nurse in the role of flow coordinator, with the focus solely on moving patients efficiently through their ED course. Three throughput metrics were used to measure ED efficiency before and after the role implementation: discharge length of stay (DCLOS), left without being seen (LWBS) and elopements. While no difference was seen in any of the three throughput metrics with regard to the sample as a whole, there were statistically significant differences between each of the throughput metrics when the sample was partitioned by age and gender. Additionally, though not statistically significant at the p < .05 level, patient satisfaction improved after the flow coordinator was implemented. These findings add to what is known about the science of ED throughput processes as they suggest a flow coordinator may improve patient satisfaction and interventions to improve flow should be individualized to patients based on their age and gender.

National and regional accrediting agencies require educational institutions to provide evidence that indicate the fulfillment of program objectives and generate results for improvement of curriculum. The Accreditation Board for Engineering and Technology (ABET) requires programs to develop and implement an evaluation process for assessing learning outcomes, reviewing achievement in the workplace by recent graduates of the program, and formulating a course of action for quality improvement of the program. Accrediting agencies require a structured plan to measure and evaluate learning outcomes and objectives, as defined by a program. They do not stipulate the methods to be used in the development of assessment and evaluation processes. However, they require that institutions demonstrate the andragogy used to achieve objectives as well as evidence of assessment and plans for continuous improvement. The study developed an evaluation model that included seven surveys for measuring the achievement of program objectives and learning outcomes, methods for scoring the results of these surveys, and techniques for presenting and comparing the measurements obtained. Committees were formed to represent industry, professional organizations and societies, science department, master’s program, local conference leaders, faculty, and IEEE student branch. The committees assessed the evaluation model. Web-based technologies were employed to deliver the surveys to students, faculty, alumni, and industry. These browser-based instruments were password protected to provide security to constituents. The university online survey system provided a database for storing data to be assessed over several semesters or terms of assessment for comparing results and determining trends.

A contingency analysis of the sequence of actions associated with agonistic behavior of resident and introduced male Sceloporus undulatus nya irthirus was carried out to determine the degree of stereotypy. During the time period April to June 1984 and 1985, caged pairs of adult male and juvenile female lizards were filmed on three occasions in order to gather data on resident males not involved in aggressive interactions. During the same threemonth time period, a different nonresident male was introduced singly into a given resident's cage on three occasions and the interactions filmed. The films were analyzed to determine which actions were agonistic, the sequence of actions and the transition frequencies from one action to another. The sequence of actions was determined to be probabilistic, that is, the occurrence of one action influenced the probability that a specific action would follow. The most probable behavioral sequence for resident males during male-male interactions was head turn-crawl-jaw snap-lateral compression-bobbing-attack. The latter three actions were unique to agonistic encounters. The introduced males expressed a similar behavioral sequence except that they very rarely attacked. The behavioral sequence of resident females during male-male interactions consisted of head turn-crawl-jaw snap-bobbing. Bobbing generally preceded jaw snapping in females when such male-male interactions were not taking place. The probabilistic nature of the display action pattern during agonistic behavior is similar to that observed in other iguanid lizards studied. Three levels of arousal were evident in resident males during aggressive interactions. These were 1) heightened awareness, 2) display and 3) attack. Again, this observation is consistent with those in studies carried out in other iguanid lizards.

Two inbred strains of mice, BALB/c and C57BL, were crossbred to produce Fl hybrids. This breeding scheme ensured a high degree of genetic heterozygosity as exemplified by the fact that the average weight of the Fl hybrids at 10 weeks of age was 10.1 percent greater that that of their contemporaries in the inbred parental strains. The three lines of mice were then challenged with a 0.5 ml intraperitoneal injection of two-percent sheep red blood cells (SRBC). After a 15-day period the mice were bled and their sera were microtitrated for anti-SRBC agglutinin and the titers statistically analyzed. The Fl mice were found to exhibit a highly significant (P < 0.0001) difference in serum antibody titers over both parental strains. Highly significant differences were also shown between the parental strains, the BALB/c mice being superior to the C57BL in antibody production to SRBC. The results of this work indicate a 177.1 percent degree of heterosis in the immune response of the Fl hybrid mice over that of their inbred contemporaries. These findings, coupled with general knowledge of animal genetics and performance, may indicate that the increased immunocompetence of the crossbred mice is directly related to their increased rate of growth.

Affordable Care Act (ACA) was passed and implemented to expand insurance coverage, reduce health care cost, and improve the quality of care. The purpose of this dissertation study was to investigate whether the ACA insurance expansion correlates with the number of visits made to emergency departments (EDs). The quasi-experimental design interrupted time series was utilized in the analysis. The ED visits were compared using MANOVA to determine the relationship between ED visits and ACA and canonical correlation analysis to assess the strength of the relationship and the extent to which independent variables could predict the dependent variable. The hypothesis was that the ACA will reduce the uninsured, increase the insured, and reduce the ED visits. The relationship between number of ED visits and the ACA will present whether the uninsured patients contributed significantly to the ED overcrowding. Analysis of secondary data from four EDs (H1, H2, H3, and H4) in the Chicago area showed that 484,742 visits were made, and 2,801 were excluded due to unknown payer type. Medicaid patients recorded the largest number of visits (181,226) while the uninsured patients recorded the least number of visits (56,572). The ED visits decreased by 6% from 2012 to 2013 (pre-ACA) and increased by 4% from 2013 to 2105 (post-ACA). The ACA implementation increased the people with insurance who visited the EDs by 11%. The results demonstrated a strong relationship between ACA and ED visits. The correlation of the variables (hospital and year) and ED visits demonstrated that the hospital could explain 97% of the Medicaid visits and 87% of uninsured while the year could predict 82.6% of the uninsured visits and 52.5% of Medicaid visits.

The neuropathogenicity of two retroviruses was investigated. The human immunodeficiency virus, in addition to its profound effect on the immune system, also causes degenerative changes in the brain, the spinal cord and peripheral nerves. In order to elucidate how it affects the nervous system, transgenic mice were generated that express the entire HIV genome in neurons in the anterior thalamus and in the anterior horn of the spinal cord, and examined clinically, neuropsychologically, electrophysiologically and histologically. Animals developed a neurological syndrome characterized by hypoactivity and weakness, and by axonal degeneration in peripheral nerves. These results provide evidence for a role of HIV in affecting both the central and peripheral nervous systems.
In a second project, pathological effects associated with a disease determining region contained in the gp70 envelope protein of the Cas-Br-E murine leukemia virus, were investigated. In infected mice, this virus causes hind limb paralysis and a spongiform myeloencephalopathy with gliosis and neuronal loss. Stably transfected fibroblasts that express gp70 were injected into the brains of mice, and the animals were examined for histopathological changes attributable to the effects of gp70. While gp70 protein was detected at the implantation site, this was not accompanied by any specific histological changes. These data suggest that the intracerebral expression of the neuropathogenic gp70 protein alone is not sufficient to cause disease, and lend indirect support to a model according to which gp70 causes disease by altering the cytokine profile of infected mononuclear cells in the central nervous system.

This study is an examination of the prevalence of asthma in adolescents, and it seeks to identify associations that may exist among individuals from different racial and socioeconomic backgrounds. The primary areas of focus were defined by the two research questions posed; these explored the differences among individuals in the study population who had a primary diagnosis of asthma and those who did not. The population consisted of children from birth to 17 years old treated in an emergency department during 2009. The National Hospital Ambulatory Medical Care Survey dataset from 2009 was used as the secondary data source for this retrospective study. After conducting a statistical analysis using a Chi-Squared test, it was determined that race has a statistically significant relationship to pediatric asthma. The factors for this correlation can be attributed to a number of theories that are discussed in detail throughout this research.

Investigations into the poor recovery of sulphadimidine from medicated animal feeds have shown that irreversible drug-feed binding, and not drug degradation, is responsible for the poor recoveries. The experimental work involved the novel use of C-sulphadimidine in analytical studies and in autoradiography of C-sulphadimidine-bound feed. The latter showed that the drug was not bound preferentially to specific feed constituents but was widely distributed on nearly all the feed particles. Further work on sulphadimidine recovery from feeds demonstrated an inverse relationship between drug recovery and feed moisture content. The role of moisture in the binding mechanism was then considered, and experiments conducted on the adsorption of moisture by feeds showed that the rate controlling mechanism was diffusion. A hypothesis is presented in which sulphadimidine is partially dissolved by the moisture in the feed and the resulting solution then diffuses into the internal regions of the feed particles via pores and cracks in the constituent particles. The deep penetration of the drug into the feed prevents the drug from being recovered by the extraction solution. Experimental evidence was found to support this hypothesis. Experimental work also investigated the causes of poor recoveries of sulphadiazine, trimethoprim and dinitolmide.

Expansion of Medicaid and private health insurance coverage through passage of the Affordable Care Act of 2010 was expected to increase primary care access and reduce emergency department (ED) use by reducing financial burden and improving affordability of care. The aim of this study was to examine the differences in utilization patterns that exist among the Medicaid population that participated in an optimal level of care (OLC) intervention inclusive of appointments scheduled to primary care providers. Using the integrated behavior model as a theoretical framework, the key research question focused on determining if there was a difference in ED use among Medicaid individuals who scheduled follow-up appointments compared to those that did not schedule follow-up appointments. The sample population consisted of 176 Medicaid enrollees who presented to the ED for treatment of nonurgent conditions and participated in an OLC intervention from June 2016 to July 2017. The results showed that there were no differences in ED utilization between the population that had scheduled appointments compared to the population that did not have scheduled appointments. A bivariate analysis on demographic variables also showed no differences in ED utilization among the variables. The social change implications of this study are that the practice of scheduling appointments with primary care providers does not reduce or affect ED utilization in the Medicaid population. This study contributes to positive social change through the findings that reducing ED utilization requires more than follow-up appointment scheduling with primary care providers. Further studies are warranted to understand the potential barriers and factors that affect ED utilization.

Traumatic injury occurs without warning leaving no time to prepare. The patient may be frightened about the unknown, their future, or the prognosis. The patient arrives in the Emergency Department (ED) where assessment and management of injuries begins. Little is known about the patient's experience of trauma resuscitation. Therefore, a qualitative study using interpretive phenomenology was undertaken to describe the lived experience of trauma resuscitation in the ED. A total of seven participants were interviewed after they experienced trauma resuscitation in the ED of a Lead Trauma Hospital. Tape-recorded interviews were conducted on the in-patient Trauma Unit between day 2 and day 7 post trauma resuscitation. Follow-up interviews were conducted with four participant's seven to twelve months after the initial interview. Data analysis utilized Colaizzi's eight-step analytical process. Four themes were revealed in the data analysis: I Remember, I Was Scared, I Felt Safe, and I Will Be OK. The findings also revealed that initial perceptions of vulnerability subsided as a sense of feeling safe became prominent. System factors were acknowledged to influence the overall conviction that it was a positive experience. Lastly, nursing interventions were important in contributing to the participants' feelings of being safe. This suggests that comfort care measures need to be at the forefront of trauma nursing care as well as measures aimed at attaining physiological stability.

The research described in this document represents work performed in the area of software development methodologies as it applied to quality software development in a scheduling department. It addressed traditional methods in software development, current trends in software development, in addition to quality and software development at various companies. The literature suggested a correlation between using a software development methodology and quality software. However, there was limited literature that measured quantitatively the correlation between the effectiveness of the software development methodology and quality software. A software development methodology was developed for the scheduling department of a government contractor company in Aiken, South Carolina based on its needs and emerging technologies. An instrument was utilized to measure the effectiveness of the developed methodology. The methodology was compared with two other methodologies: a standard methodology from the literature and the current method of software development in the scheduling department. A population of computer professionals was divided into three equal groups. Each group was asked to apply the methodology to the case study. Individuals in each group were asked to review the case study and software development methodology. Then using the instrument, the individuals were asked to evaluate the effectiveness of the software development methodology, thereby providing a means for evaluated effectiveness, without conducting years of testing. The responses of the three groups were compared to one another. The results indicated a significantly higher level of approval for those methodologies that guided the development activities, standardized the development process, and identified the development phases and deliverables. It was concluded that utilizing a software development methodology that guides, standardizes, and defines the development phases and deliverables will result in an improved software development process and software quality. Further investigation could validate the findings of this research. The results actually achieved from utilizing the methodology developed for the scheduling department compared with the results achieved from utilizing some other methodology could further validate these research findings. Additional research could examine, over an extended time period, the success of the software development process and software quality of those projects utilizing the methodology described in this dissertation.

The nutritional value for the following species have been determined: P.pallida, P.laevigata var. andicola, P.flexuosa, P.nigra, P.alba of the genus Proposis. To obtain this purpose surveys were done about the use and consumption of the Carob Tree in the High and Central Valleys of the Cochabamba Department. As a result of the surveys it was determined that the consumption of the pods made up for 54% of human nourishment. The species that were consumed the most were P.pallida and P.laevigata var. andicola. Within the uses of these leguminous pods, the pods are directly consumed in their raw form and on a lesser scale in their cooked form. It was also observed that a minority use it as flour which is then ingested principally in the form of pito and api. Afterwards a chemical bromatologic analysis was done and it was determined that there was a high content of carbohydrates and fiber, a relatively good percentage of protein and a low ethereal extract, standing out more than the minerals calcium and iron. It was also determined that the highest content of protein and ethereal extract show P.laevigata var. andicola and P.nigra, the fiber P.laevigata var. andicola, and P.pallida calories. The species with the most concentration of the minerals phosphorus, iron, and calcium were P.pallida and P.nigra. The biological tests for the protein quality performed for the two species that were the most consumed show poor results of Real Digestibility (Dr), Net Use of Real Protein (UNPr), Real Biological Value (VBr), and the Relation of the Efficiency of Protein (PER). These are considerably becoming better through a thermic process (toasted 10min). The leguminous cereal complementation (corn-carob tree), favorably increased all of the biological indexes. The species P.pallida showed superiority compared to the results obtained for P.leavigata var. andicola. In the meantime these species can be considered a good energy source and with the combination of cereals can effectively cover caloric protein deficiencies.

Introduction. The treatment of cellulitis with intravenous antibiotics administered in Emergency Departments is a new phenomenon with significant inter-physician variation. A clinical trial will address many of the questions surrounding this practice. Previous trials have been flawed because of the absence of a validated objective outcome measure. Methods. Eligible patients with cellulitis were prospectively recruited for an observational cohort study and underwent daily measurements of their infection. These measurements were evaluated for their feasibility, inter-rater reliability and criterion validity (compared with the primary outcome of treatment failure versus clinical response; a classification based on physician treatment decisions) Results. Only the infection size and change in size over time performed well, obtaining statistical significance in all domains. Conclusions. The change in size of infection over time is a valid and reliable reflection of clinical decisions for patients with cellulitis, and should be used as the primary outcome for clinical trials of cellulitis therapy.

Background: The provision of high quality medical and surgical care is predicated by high quality education and training. This enables staff to respond more effectively and flexibly and is crucial when considering the various factors impacting upon the delivery of patient care. The development and training of all healthcare students and staff is an important factor in ensuring patient safety and self satisfaction, and relies on understanding the needs of learners as well as the way in which they learn. This fundamental training and education is no less pertinent in the perioperative environment, where high impact interventions are performed by Operating Department Practitioners (ODPs), and where patient safety and the quality of care must be paramount. This is due to the often difficult and potentially dangerous surgical and anaesthetic interventions on elective, unscheduled or critically ill patients. Aim: The aim of this programme of research was to investigate the effectiveness of ‘traditional’ lecture/placement provision in ODP education, resulting in the implementation and evaluation of a revised curriculum that integrates simulation based teaching and learning for this group of allied health professionals at the University of Portsmouth. Methods: This programme of research used a mixed methods QUAL + quant approach on multiple purposive and convenient samples of ODP students and placement education managers. Drawing on phenomenographic methodology, the interpretivist studies used semi-structured interviews and focus groups to investigate the understanding and perceptions of learning from those with relevant lived experiences. Furthermore, a positivist study was conducted to analyse and further understand the effectiveness of different teaching methods. The results from these studies informed a revision of the traditional ODP curriculum, based upon a nursing conceptual framework that included the integration of simulation-based learning. Results: A total of five studies were conducted, beginning with individual semi-structured interviews with 12, second year ODP students investigating perceived enablers and barriers to traditional learning using lectures in University and placement learning in the hospital environment. Study Two continued with a positivist study on a cohort of first year ODP students, which investigated the effectiveness of three types of teaching. The results of these first two studies informed a revision of the traditional ODP curriculum to integrate simulation-based learning. The revised curriculum was subsequently evaluated using focus group interviews and follow up interviews, with 30 first year ODP students. Finally, a focus group interview with 12 clinical educators that are responsible for the clinical placement learning for ODPs was conducted to gather their perceptions of the revised curriculum, and the clinical performance of the students. This led to the development of a conceptual framework to inform the integration of simulation-based learning into future ODP courses. Conclusions: The results of this research demonstrate that simulation-based learning for this professional group of ODP learners showed an encouraging trend in its effectiveness compared to other teaching methods. The revised curriculum encouraged higher order learning and mitigated to some extent the challenges faced by the NHS and placement educators. In addition, revising the ODP curriculum was evaluated positively by participants and clinical educators and tackled challenges such as inequity of learning opportunity and exposure to a diverse range of patient groups, that learners often face when undertaking learning on clinical placement. The conceptual framework designed to inform the curriculum identified specific areas for consideration when integrating simulation-based education into the ODP curriculum. However, further development and comparison of the conceptual framework reported here and a larger cross-university sample is needed to confirm its reliability and validity.
