Dudin CONSUMERS ’ PERCEPTIONS AND ATTITUDES WHEN EVALUATING BRAND EXTENSIONS IN RELATION TO THE ORIGINAL BRAND : A SOUTH AFRICAN PERSPECTIVE

The purpose of the study was to investigate consumers’ perceptions and attitudes when evaluating brand extensions in relation to the original brand within a South African context. Furthermore, this study examines how consumers perceive the overall quality and similarity/fit of the brand extensions (Nike camera, Nike socks, and Nike golf balls) in relation to the original brand (Nike athletic shoes) and how these perceptions influence their attitudes towards the extensions. In order to get these insights, the study surveyed 147 undergraduate and postgraduate students from the University of the Western Cape across all faculties. A non-probability convenience sampling method was used to access respondents. To collect data, qualitative and quantitative methods were JIBC May 2017, Vol. 22, No.S8 2 employed using a questionnaire which consisted of open-ended and closed-ended questions in the form of free associations technique and 5-point Likert scales. The data gathered was analysed by means of descriptive statistics and Spearman correlation coefficient. The findings indicate two key aspects. First, respondents only perceived Nike socks’ overall quality to be congruent to the original brand (Nike athletic shoes). Second, respondents only perceived Nike socks to be strongly similar to the original brand (Nike athletic shoes). Despite this, respondents had a favourable attitude towards all the brand extensions irrespective of whether they perceived the overall quality of the extensions to be congruent to the original brand or not, and whether they perceived the extensions to be similar to the original brand or not. These factors did not influence respondents’ attitudes towards the extensions negatively. The research therefore proposes that the perceived overall quality of the brand extensions will be congruent to that of the original brand and that the attitude towards the brand extensions will be favourable only when there is a perceived similarity/fit between the brand extensions and the original brand.

Massey products in the Galois cohomology of number fields

In this thesis we study the relation structure of the Galois group of the maximal outside a given set S unramified p-extension QS(p) of Q and of the Galois group of the p-class field tower of a quadratic number field, where p is a prime number. These groups can be presented in terms of generators and relations by theorems due to Koch. Here the relations are elements of the free pro-p-group F on a certain minimal system of generators of the above Galois groups. They can be described by class field theory modulo the third step F(3) of the Zassenhaus filtration of F . We assume that the relations lie inside F(3) and study the structure of the relations modulo the fourth step F(4) of the Zassenhaus filtration of F . For p = 2 we give an explicit description of these relations. Our approach is based on the observation that the above Galois groups have a similar structure as groups of links occuring in knot theory. We carry over techniques of knot theory to our situation. In particular we study the Fox differential calculus on free pro-pgroups and Massey products in the cohomology of pro-p-groups, and we give a cohomological interpretation of this differential calculus. This is a generalization of the well-known relationship between the cup product in the cohomology of a pro-p-group and its relation structure. Therefore we are able to show a number theoretic analogue of the theorem of Porter-Turaev from knot theory. It describes a connection between certain Massey products in the cohomology of the Galois group of QS(p)/Q and the Milnor invariants of this group introduced by Morishita. We generalize Morishita’s results on the Milnor invariants for QS(2) and obtain a complete description of the triple Massey product on the cohomology group H(G(QS(2)/Q),Z/2Z), and thereby of the relation structure of G(QS(2)/Q) modulo F(4). While the relation structure modulo F(3) is closely linked to the Legendre symbol by Koch’s results, the relation structure modulo F(4) is intimately connected to the so-called Rédei symbol on S. This triple symbol was introduced in the thirties of the last century by Rédei. We use the results on the Galois group of QS(2)/Q in order to deduce information on the Galois group of the 2-class field tower of a quadratic number field by means of a descent procedure. We give a partial description of the sought-after relation structure and show that is closely connected to the Rédei symbol on the set of prime divisors of the discriminant of the quadratic number field.
Autoantibody Profile and Its Association with Clinical Presentation of Paediatric SLE Patients

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of various auto antibodies including anti-nuclear antibody, double stranded DNA and antibodies to extractable nuclear antigens (ENA), which include four groups of RNA binding protein namely Sm, RNP, SSA/Ro and SSB/La. The objectives were to detect the frequency and pattern of ANA, frequency of anti- ENA antibodies and association between the clinical presentations with ANA and Anti-ENA antibodies in paediatric SLE patients. It was a cross sectional study and the data was collected from patients fulfilling the ACR 1997 revised criteria of SLE in the Department of Paediatrics, BSMMU, Dhaka, Bangladesh. Among 50 paediatric SLE patients, ANA was positive in 94% of the patients. Homogenous pattern of ANA was the highest (57%) followed by speckled (31%), cytoplasmic (6.6%) and nucleolar (3.3%) patterns. Anti-ds DNA positivity was 86% and anti-ENA positivity was 56% in this study. Among them, anti–RNP was found in 43.5% followed by anti-sm (24%), anti-SSA (24%) and anti-SSB (17%). Anti–RNP antibody was associated with renal and gastrointestinal and Anti–SSA was associated with only gastrointestinal manifestations. ANA, anti ds-DNA, anti ENA positivity were found significantly among paediatric SLE patients and clinical presentation of them had association with Anti-ENA antibodies.
Impacto del virus de la hepatitis C en las complicaciones inmediatas y los trastornos metabólicos glucémicos del trasplante renal

La infección por el virus de la hepatitis C (HVC) impacta de forma negativa en la evolución del trasplante renal al asociarse a las complicaciones en el postrasplante inmediato y los trastornos de la glucemia. Se realizó esta investigación con los objetivos de conocer las características que rodean a los enfermos anti HVC + que reciben un injerto renal, sus principales complicaciones en el postrasplante inmediato y los trastornos metabólicos glucémicos que los acompañan. Los datos se obtuvieron del registro de trasplantes renales (TR) del hospital "Hermanos Ameijeiras", de todos los primeros TR a partir del año 1995. Los pacientes que recibieron un trasplante renal y padecían HVC sobresalieron al compararlos con los que no estaban infestados por el virus C, por un mayor tiempo en diálisis (meses), 28,76 ± 7,09 vs. 14,24 ± 7,05, p = 0,046, mayor frecuencia de necrosis tubular aguda 48,7 vs. 35,05 %, p = 0,032, niveles elevados de ciclosporina A al tercer mes de trasplante y frecuente nefrotoxicidad por esta droga. La incidencia de diabetes mellitus postrasplante fue de 61,2 % (HVC) vs. 32,1 %, p = 0,00017. Se les realizó a 83 pacientes: 39 anti HVC positivo (46,9 %) y 44 anti HVC negativo (53,1 %), una prueba de tolerancia a la glucosa oral con dosificación de insulina y cálculo de los índices HOMA. El 62 % de los anti HVC positivo presentaron hiperglucemia asociada al TR mientras que esto solo ocurrió en el 39 % de los negativos. También fueron más insulinorresistentes con una media de HOMA R de 5,66 ± 4,86 vs. 3,65 ± 2,9, p = 0,004, así como menos secretores de insulina, HOMA B% 154,28 ± 116 vs. 239 ± 166,9, p = 0,0032.
EVALUATION OF DNA METHYLATION OF FGFR 2 GENE IN BREAST CANCER

DNA methylation is one of the Epigenetic marks at the cytosine residue of CpG dinucleotide. Epigenetic biomarkers can be used at any stage of a disease such as cancer, as diagnostic biomarkers, prognostic biomarkers and predictive biomarkers. Several genes have been identified as an Epigenetic biomarker in breast cancer. This study has evaluated breast cancer samples and normal samples to identify epigenetics biomarkers for breast cancer. DNA was extracted from peripheral blood of the 30 breast cancer samples and the 30 normal samples. Here was used a method for DNA methylation analysis that is based on digestion DNA with a methylation sensitive restriction enzyme and PCR amplification with gene-specific primers (MSRE-PCR method). FGFR2 gene is no significantly hypomethylated in breast cancer samples compared to normal samples which is analyzed with P value (P>0.05). Results of this study haven’t showed any change in methylation of FGFR2 gene in breast cancer; nevertheless, more quantitative and detailed studies should be done in the future.
ELDAS radiation and heating rates products using METEOSAT data

METEOSAT data have been used to create two ELDAS data bases: surface radiation using the ELDORADO system, and surface heating rates that is considered to contain information on soil wetness. ELDORADO data have been used in the data assimilation experiments of ECMWF, and are shown to behave properly. Heating rate data have been analyzed in terms of differences between low and high vegetation fractions, and between two years with different hydroclimate (2000 and 2003). Initial experiments with a limited area version of the ECWMF physical parameterization package showed a systematic low bias of simulated heating rates. Most of this bias has pragmatically been removed by updating the thermal roughness length in the model. Data assimilation experiments with the limited area model are imminent.
BERT-A : Fine-tuning BERT with Adapters and Data Augmentation

We tackle the contextual question answering (QA) problem on the SQuAD 2.0 dataset. Our project has two main objectives. Firstly, we aim to build a model that achieves a reasonable performance while keeping the number of trainable parameters to a minimum. In this regard, we insert task-specific modules inside the pre-trained BERT model to control the flow of information between transformer blocks. Our proposed method for fine-tuning BERT achieves comparable performance to fine-tuning all BERT parameters while only training 0.57% of them. Secondly, we use our findings in the previous task to achieve an EM score of 78.36 and an F1 score of 81.44 on the test set (ranked 3rd on the PCE test leaderboard).
One-class Classification : ν-SVM

One-class classification is a special kind of classification problem, for which the training set only consists of samples from one class. Conventional SVM fails to handle the one-class classification problem because of the lack of information from the other class. The ν-SVM addresses this issue by estimating the probability density support of the class that we have sufficient samples, and then treat new samples outside of the support as outliers. The resulting optimization problem can be readily solved in a similar way as the conventional SVM, and its generalization error can also be theoretically upper bounded. Both simulation and real medical data are used to demonstrate the performance of ν-SVM in this report, which should prove useful in various outlier/abnormity detection tasks.
Biopharmaceutical classification of desloratadine – not all drugs are classified the easy way

Abstract The biopharmaceutical classification of drugs was designed as a basis for bio-waivers – a mechanism with the double ethical benefit of delivering new drug formulations to the market with less human testing and lower cost. However, many drugs defy simple classification because in vitro permeability and stability assessment can be challenging as shown in this study for desloratadine. Literature shows that desloratadine is highly soluble, while data on luminal stability and permeability are circumstantial. Combined with borderline bioavailability and not really known fraction of absorbed dose, desloratadine was found to be a good example for showing the innovative in vitro approaches necessary to unambiguously classify desloratadine according to Biopharmaceutical Classification System (BCS) guideline. Presented study undoubtedly confirmed that desloratadine solubility is high and dissolution is very rapid for immediate release reference tablets. We have demonstrated deslorata-dine stability under legally required conditions and also in more physiologically relevant media. High in vitro desloratadine permeability was confirmed using Caco-2 and Parallel Artificial Membrane Permeability Assay (PAMPA). Well-established in vitro model with rat intestinal tissue could not be used due to reasons elaborated in this paper.

PROPOSED MEASUREMENT MODEL FOR UNDERSTANDING FACTORS INFLUENCING KNOWLEDGE SHARING

Research confirms that the factors that promote or discourage knowledge-sharing behaviour in businesses are poorly understood and that knowledge management systems fail due to the misunderstanding of, amongst others, individual characteristics that could influence knowledge sharing. Moreover, the focus of knowledge-sharing literature, in terms of the unit of analysis, is rarely at an individual/micro level, although individuals’ role in the knowledge-sharing process is critical as tacit knowledge resides within the individual and knowledge sharing starts with individuals. The objective of this paper is to propose a model and measurement of individual-related factors influencing knowledge-sharing intention of individuals in knowledge-intensive businesses. The literature review revealed twelve constructs, namely individuals’ awareness, intrinsic motivation, extrinsic motivation, transactional psychological contract breach, relational psychological contract breach, relationship conflict, task conflict, extraversion, neuroticism, openness to experience, agreeableness and conscientiousness that could influence the dependent variable knowledge-sharing intention in knowledge-intensive businesses. Various moderating relationships between the dependent and independent variables are also proposed, while seven demographic variables (age, gender, language, highest qualification, ethnic background, organisational tenure and job tenure of the respondent) are identified as potential influencing factors. Understanding and managing these factors could contribute to an increase in knowledge sharing among employees, and as a result, enhance the effectiveness and competitive advantage of knowledge-intensive businesses.

Hyperthermic intraperitoneal chemotherapic perfusion in colorectal cancer

The term peritoneal carcinomatosis (PC) includes all tumoral dissemination, either local or massive, to the peritoneal serosa and neighbouring anatomical structures. The term PC was first used by Simpson in 1931 to describe the peritoneal dissemination of an advanced ovaric cancer (1).
A Namibian version of the 28 item General Health Questionnaire : research article

Background : Namibia faces a daunting array of mental health problems. However, there is no Namibian screening instrument for psychological distress. Aim : To develop a Namibian version of the 28 item General Health Questionnaire (GHQ-28). Methods : A consecutive sample of 159 Oshiwambo speaking patients attending rural health clinics in the north of Namibia were enrolled in the study. Basic demographic data were collected and subjects asked to complete the GHQ-28 that had been translated into Oshiwambo. Thereafter all subjects were interviewed with the Clinical Interview Schedule (CIS). Using the CIS data as a marker for psychiatric caseness, the sensitivity, specificity, and receiver operating characteristics (ROC) of the Oshiwambo GHQ-28 were assessed. Results : Based on a 0-0-1-1 scoring system, the Oshiwambo GHQ-28 was found to have a sensitivity of 82.1% and a specificity of 79.4%. The ROC analysis revealed good discriminating power with an area under the curve of 0.86 Conclusions :The Oshiwambo version of the 28 item GHQ is a valid screening instrument for psychological distress in clinic attendees.
Tear level of nerve growth factor in normal dogs

Purpose To evaluate tear level of nerve growth factor (NGF) in normal dogs. Methods In the present study we investigated the presence and the level of NGF in the tear of 12 normal dogs (24 eyes) with different sex (5 males and 7 females) and age (ranging from 2 to 12 years old). Tears were collected by washing the eye surface 150 microliter of physiological salt after clinical examinations. Tear samples were stored at -20°C until tested for presence of NGF performed with a commercially available immunoenzymatic assay and expressed as pg/ml of sample. Results All samples examined showed presence of NGF, suggesting that this growth factor is a constitutive biological mediator of the ocular surface. It was also found that the level of NGF in the right eye is different from the left eye. Thus, the average concentration in the tear of the right was 7,97 (ranging from 5.0 to 38.3 pg/ml), whereas the average in the left eyes was 15,79 (ranging from 5.0 to 67.5 pg/ml). Conclusion Tear fluid is a secretion of lacrimal gland that lubrificates the eye surface and plays a critical role in response to eye irritation, by improving optical performance and the deficit induced by keratoconjuntivitis sicca. The observation that NGF is present in tear of dogs in a physiological relevant amount suggests that this molecule may be involved in the regulation of corneal homeostasis. Moreover, as NGF is known to play a role in emotional and anxiety-like behaviour, and tear secretion is a widespread phenomena among vertebrates, the possibility exists that NGF might be also involved in these behaviour responses. Because cats rarely suffer from emotional behavioural and keratoconjuntivitis sicca further studies may help to understand the role of NGF in tear secretion.
Trade-Offs in Operating Room Planning for Electives and Emergencies: A Review

The planning of the operating rooms (ORs) is a difficult process due to the different stakeholders involved. The real complexity, however, results from various sources of variability entering the processes. These uncertain processes cannot be ignored since they greatly influence the trade-offs between the hospital costs and the patient waiting times. As a result, a need for policies guiding the OR manager in handling the trade-offs arises. Therefore, researchers have investigated different possibilities to incorporate non-elective patients in the schedule with the goal of maximizing both patient- and hospital-related measures. This paper reviews the literature on OR planning where both elective and non-elective patient categories are involved. It shows the various policies, the differences and similarities in the research settings and the resulting outcomes, whether they are beneficial or not. We find that the dedicated and the flexible policy are mostly pursued, but the setting and the assumptions of the reviewed papers vary widely. Decisions on both operational policies as well as on capacity are required to assure timely access and efficiency, which are the two main drivers for the problem at hand. Furthermore, the policy choice impacts the number of schedule disruptions and the OR utilization. However, results on the overtime and the patient waiting time are partly contradicting. The review shows that some policies have already received considerable attention, but the question of which policies are most appropriate is not yet fully answered. Neither has the full spectrum of policies been explored yet. Consequently, this topic provides several areas for future research, which are outlined throughout the paper.
Variante poco frecuente de meningiomas: meningiomas quísticos

Objective. To describe two (2) unusual cases of intracranial cystic meningioma whose diagnosis before surgery represents a great challenge. Description. Case No 1: male, 43 years old with generalized seizure. Ct scan shows a right frontal cystic tumor. Case No 2: female, 44 years old, with behavioral disorder and right brachiocrural palsy. Ct scan shows a left frontal cystic tumor Intervention. In both cases surgery was performed with total resection of the tumor and the diagnosis was cystic meningioma. Very good results were obtained after surgery. Conclusion. Before surgery the diagnosis of cystic meningioma is seldom made. For this kind of cases, the treatment is, even now, a surgical procedure and in some cases radiotherapy.
Probiotics and Atopic Dermatitis

Atopic Dermatitis is a common disease characterized by inflamed, itching and dry skin. This relapsing allergic disorder has complex etiology and shows a remarkably high clinical heterogeneity which complicates the diagnosis and clinical management. This book is divided into 4 sections. The first section (Disease Etiology) describes some of the physiological mechanisms underlying Atopic Dermatitis, including alterations in the immune system and the skin-barrier function. The important role of host-microorganism interactions on the pathophysiology of Atopic Dermatitis is discussed in the second section (Microorganisms in Atopic Dermatitis). An overview of the clinical diagnostic criteria and the disease management protocols commonly used is given in the third section (Diagnosis and Clinical Management). The last section (New Treatments) describes new therapeutic approaches that are not widely used but are currently being studied due to preliminary evidence showing a clinical benefit for Atopic Dermatitis.
