    Text in English with abstracts in Zulu and AfrikaansDespite its substantial growth and contribution to the economy of the country, the South African retail industry is faced with various challenges, including customers’ changing buying habits and expectations, the evolution of e-commerce, the entry of giant retailers into the retail market, and the growing importance of the urbanised middle class and its potential purchasing power. This creates risks that are mostly beyond retailers’ control. Therefore, there is a general drive among retail brands to build customer loyalty in order to respond to these contemporary dynamics within the industry and, ultimately, enhance sustainability. It is noted from literature that current understanding of customer behaviour in the South African retail space is largely the result of rational behavioural measurement, while the subconscious behaviour of customers is often neglected. The study on which this thesis reports attempted to address this gap in the current knowledge base. The current study makes a novel contribution to knowledge in using complementary traditional and neuromarketing instruments in a sequential mixed method research design to measure verbal, non-verbal and physiological emotions, which indicate the key influential cognitive and emotive factors shaping shopping decisions. For a comprehensive understanding of customer behaviour, the study primarily explored the emotional antecedents of customer loyalty in the formal retail industry of South Africa. In order to explore and describe both retail brands and customers’ experiences regarding the drivers of retail brand loyalty, the empirical phase of the study adopted a sequential mixed method research design. This design comprised eight individual semi-structured interviews, which focused on and explored the fundamentals of behavioural and attitudinal loyalty within the context of a customer relationship management strategy. x Based on the findings emerging from the quantitative mall intercept survey with 300 retail customers, the study identified the motivating factors of greatest likelihood among customers that best explain retail brand loyalty, namely product quality, convenience of location, customer care, product variety and availability, as well as fair pricing. Furthermore, findings emerging from the inferential analysis (structural equation modelling, two-step cluster analysis, optimal scaling and multivariate binary regression analysis) showed that brand trust, brand affect and attitudinal loyalty are key predictors of behavioural loyalty. Additionally, customer loyalty differs depending on customer predisposition towards the major retail brands tested. In this regard, Pick n Pay, Massmart and Shoprite/Checkers recorded the most favourable perceptions among customers.

In this regard, Pick n Pay, Massmart and Shoprite/Checkers recorded the most favourable perceptions among customers. As a complement to the quantitative research phase of the study, a Self-Assessment Manikin attitude measure was applied to a sample of 120 customers. This phase of the study highlighted pertinent emotional elements as key mediators in securing sustainable retail brand loyalty. In this regard, Woolworths and Pick n Pay recorded the most favourable perceptions on four stimuli, namely quality, customer rewards, customer care and brand logos. The study also applied eye tracking and galvanic skin response techniques to a sample of 10 participants to determine customers’ psychophysiological reaction to the four stimuli. Galvanic skin response findings showed that customers were especially engaged with Spar, Shoprite/Checkers and Pick n Pay, while eye tracking findings showed customers’ higher visual engagement with Shoprite/Checkers, Pick n Pay and Spar. A key overall finding of this study was the significant role of feelings and emotions in driving customer loyalty. Retail brands lose relevance when they fail to connect emotionally with customers, and without that emotional attachment, brands can easily be replaced by generic imposters. A comprehensive understanding of customer behaviour remains a quandary for marketing and business practitioners. In an attempt to address this limitation, the current study used insights from non-verbal attitudinal and psychophysiological measures to obtain a more comprehensive behavioural understanding of retail customers.Nakuba imboni yezitolo ezihwebayo yaseNingizimu Afrika ibonise ukukhula nokudlondlobala okukhulu futhi idlala indima esemqoka emnothweni wezwe, ibhekene nezinselelo eziningana futhi ezihlukahlukene, kubandakanya indlelakuthenga yamakhasimende eguquguqukayo kanye nalokho okulindelwe ngamakhasimende nezimfuno zawo, ukungenisa ngezinkani kwemboni yokuhweba nge-intanethi nobuxhakaxhaka bobuchwepheshe besimanjemanje, ukungena kwezitolo eziyizikhondlakhondla emakethe yezitolo ezihwebayo, kanye nokukhula kokubaluleka kwabantu abahlala emadolobheni abasesigabeni sempilo esimaphakathi kanye namandla abo okuthenga.

Mayelana nalokhu, abakwa-Woolworths kanye nabakwa-Pick n Pay babonisa ukuthandwa kakhulu ngamakhasimende mayelana nezici-bunjalo ezihehayo futhi ezikhuthazayo ezine, okuyikhwalithi, imivuzo yamakhasimende, ukunakekelwa kwamakhasimende kanye nemibala egqamile, igama elidumile nezimpawu zesitolo. Ucwaningo lwasebenzisa futhi nezindlela zokucwaninga eziphathelene nokulandela umkhondo wamehlo amakhasimende kanye nezimpawu zemizwa yamakhasimende ezibonakala esikhumbeni semizimba yawo, okuyizindlela zocwaningo ezasetshenziswa kubabambiqhaza bocwaningo abayi-10 ngenhloso yokuhlonza indlela-kusabela kwamakhasimende ephathelene nengqondo nomzimba kulezi zicibunjalo ezikhuthazayo futhi ezihehayo ezine ezishiwo ngenhla. Imiphumela yendlela yocwaningo ebheka izimpawu zemizwa yamakhasimende ezibonakala esikhumbeni semizimba yawo yabonisa ukuthi amakhasimende ahehelekela ikakhulukazi kwabakwa-Spar, Shoprite/Checkers kanye nabakwa-Pick n Pay, kanti ngakolunye uhlangothi imiphumela yendlela yocwaningo ebheka futhi ilandele umkhondo wamehlo amakhasimende yabonisa ukuheheka kwamehlo okuphakeme ezitolo zabakwa-Shoprite/Checkers, Pick n Pay kanye nabakwa-Spar. Umphumela omkhulu futhi osemqoka otholakale kulolu cwaningo yindima ebaluleke kakhulu edlalwa yimizwa ekukhuthazeni ukwethembeka kwamakhasimende. Izitolo zilahlekelwa yiwozawoza yazo kumakhasimende uma zihluleka ukuxhumana namakhasimende ngokwemizwa, futhi ngaphandle kwalokho kuxhumana ngokwemizwa nokuzwana, izitolo zingazithola kalula zisesimweni lapho indawo yazo isithathwe yizitolo-mbumbulu ezingosandanezwe. Ukuqondakala okuphelele kwendlela aziphatha ngayo amakhasimende futhi enza ngayo izinto kusalokhu kuyinkinga nesithiyo esikhulu kwizazi nezisebenzi ezenza umsebenzi wokukhangisa nokuqhuba ibhizinisi. Njengomzamo wokubhekana nalesi sithiyo, lolu cwaningo lusebenzise ulwazi nokuqonda okujulile okutholakale kwizikali zendlela-kubuka yamakhasimende kanye nezikali zesimo sengqondo nesomzimba samakhasimende ukuze kutholakale ukuqonda okuphelele futhi okujulile okuphathelene nokuziphatha kwamakhasimende athenga ezitolo kanye nendlela enza ngayo izinto.Ondanks sy stewige groei en aansienlike bydrae tot die landsekonomie, het die Suid-Afrikaanse kleinhandelsbedryf met verskeie uitdagings te kampe. Veranderinge in kliënte se koopgewoontes en verwagtings, groeiende e-handel, reusekleinhandelaars wat die kleinhandelsmark betree, die toenemende invloed van die verstedelikte middelklas en sy potensiële koopkrag is enkele hiervan. Dit gee aanleiding tot risiko’s wat grotendeels buite die beheer van kleinhandelaars is. As gevolg van die hedendaagse dinamiek in die bedryf, poog kleinhandelsmerke om kliëntlojaliteit te verstewig en hulle eie volhoubaarheid te verseker. Dit blyk uit die literatuur dat die kleinhandelsektor se siening van kliëntgedrag in Suid-Afrika op die meting van rasionele gedrag berus, en dat die onbewuste gedrag van kliënte verontagsaam word. Hierdie tesis doen verslag van ʼn studie om hierdie leemte in die huidige kennis te probeer aanvul. Dit lewer ʼn bydrae deur aanvullende tradisionele en neurobemarkingsinstrumente in ʼn opeenvolgende gemengde metode as navorsingsbenadering te gebruik. Verbale, nieverbale en fisiologiese emosies is gemeet aangesien hulle die kognitiewe en emotiewe faktore is wat inkopiebesluite bepaal. Hierdie studie het hoofsaaklik die emosionele antesedente van kliëntlojaliteit in die Suid-Afrikaanse formele kleinhandelsbedryf verken om ʼn grondige begrip van kliëntgedrag te kry. Ten einde kleinhandelsmerke en kliënte se ervarings van die drywers van kleinhandelsmerklojaliteit te beskryf en te verken, is ʼn opeenvolgende gemengdemetode-navorsingsontwerp gevolg. Dit het uit agt halfgestruktureerde, private onderhoude bestaan. Hierin is gekonsentreer op die grondslae van gedragsen houdingslojaliteit teen die agtergrond van ʼn kliënteverhoudingsbestuurstrategie. Op grond van die bevindings van ʼn kwantitatiewe winkelsentrumopname onder 300 kleinhandelskliënte, is die motiveringsfaktore met die grootste waarskynlikheid aangetoon. Hulle is produkgehalte, ʼn gerieflike ligging, kliëntesorg, produkverskeidenheid, beskikbaarheid en billike pryse, en bied die aanneemlikste verklaring vir kleinhandelsmerklojaliteit. Volgens die bevindings van die inferensiële ontleding (struktuurvergelykingmodellering, tweestaptrosontleding, optimale skalering en meerveranderlike binêre regressieanalise) is merkvertroue, merkaffek en houdingslojaliteit betroubare aanwysers van bedragslojaliteit. Afgesien hiervan verskil kliëntlojaliteit na gelang van kliëntpredisposisie jeens kleinhandelsmerke wat getoets is. Kliënte was vir vier stimuli (naamlik gehalte, kliëntbelonings, kliëntesorg en merklogo’s) die ontvanklikste vir Pick n Pay, Massmart en Shoprite/Checkers. Aanvullend tot die kwalitatiewe navorsingsfase van hierdie studie is ʼn selfasseringsmodelhoudingmeting op ʼn steekproef van 120 kliënte toegepas. Hierdie fase het die aandag gevestig op pertinente emosionele elemente as sleuteltussengangers in die opwekking van volhoubare kleinhandelsmerklojaliteit. Vir die vier stimuli (naamlik gehalte, kliëntbelonings, kliëntesorg en merklogo’s) was kliënte se persepsies van Woolworths en Pick n Pay die gunstigste. Hierbenewens is oogvolg- en galvaniese velreaksietegnieke op ʼn steekproef van 10 deelnemers toegepas om hulle psigofisiologiese reaksie op die vier stimuli te bepaal. Die galvaniese velreaksietoetse het aangedui dat kliënte besonder ontvanklik was vir Spar, Shoprite/Checkers en Pick n Pay, en volgens die oogvolgtoetse visueel meer aangetrokke tot Spar, Shoprite/Checkers en Pick n Pay was. Hierdie studie het bevind dat emosies in die algemeen ʼn deurslaggewende rol in kliëntlojaliteit speel. Kleinhandelsmerke raak irrelevant as hulle nie ʼn emosionele band met kliënte smee nie. Sonder hierdie emosionele verbintenis kan generiese bedrieërs maklik die plek van kleinhandelsmerke inneem. Bemarkings- en sakepraktisyns het nie ʼn deeglike begrip van kliëntgedrag nie. Om dit reg te stel, het hierdie studie nieverbale houdings- en psigofisiologiese toetse toegepas om die gedrag van kleinhandelskliënte beter te begryp.Business ManagementD. Com. (Business Management

    Emotive reactions to the consumer education project of the South African dairy industry

    Historically, consumer perceptions towards dairy products have been measured using a rational cognitive approach. However, recent consumer insights suggest that emotions play a dominant role in consumer decision making. The South African dairy industry therefore identified a need to determine emotive reactions to educational messages in addition to the reasons underpinning dairy consumption. Using a mixed method research approach, reactions from 81 South African dairy consumers were obtained, using three different, but interrelated measuring instruments. Descriptive statistics, hierarchical ladder maps and correlation analyses were used to examine emotive and cognitive consumer reaction to a number of generic dairy messages and products. The findings indicate that certain communication messages appear to have a stronger impact on consumers due to specific emotions that these messages elicit. Personal values underpinning dairy consumption decisions were also identified within the context of emotive reactions to the selected dairy products.Business ManagementM. Com. (Business Management

    Principales Maladies Zoonotiques des Porocs (Sus scrofa domesticus) a l’Abattoir de la Societe Ivoirienne d’Abataage et de Charcuterie de Yopougon (Abidjan, Cote d’Ivoire)

    Une étude sur les maladies zoonotiques des porcs (Sus scrofa domesticus) abattus à l’abattoir de la Société Ivoirienne d’Abattage et de Charcuterie a été conduite de septembre 2020 à septembre 2021. Elle avait pour objectif de connaître les motifs de saisies pour cause d’agents pathogènes susceptibles de transmettre des maladies zoonotiques aux consommateurs. Pour ce faire, 32 301 porcs abattus en provenance de 11 localités ont été l’objet d’examens post-mortem réalisés par les services vétérinaires.  Les résultats indiquent que les pathologies zoonotiques identifiées ont été la distomatose, l’échinococcose ainsi que des cas de suspicion de tuberculose. L’échinococcose a été la zoonose la plus fréquente (91,54%) alors que la tuberculose a été la zoonose la plus distribuée dans les organes (100%). La distribution des maladies zoonotiques a varié avec l’organe infecté ainsi que la localité de provenance des porcs abattus. Pour limiter les risques de transmission des zoonoses, des inspections sanitaires systématiques doivent être effectués par les services vétérinaires afin de de prévenir des problèmes éventuels de santé publique.   A study on zoonotic diseases of pigs (Sus scrofa domesticus) slaughtered at the slaughterhouse of the Ivorian Slaughterhouse and Charcuterie was conducted from September 2020 to September 2021. Its purpose was to find out the reasons for seizures due to pathogens that could transmit zoonotic diseases to consumers. To this end, 32,301 slaughtered pigs from 11 locations were subjected to post-mortem examinations by veterinary services.  The results indicated that the zoonotic pathologies identified were distomatosis and echinococcosis. However, suspected cases of tuberculosis have been observed. Echinococcosis was the most common zoonosis (91.54%) while tuberculosis was the most distributed zoonosis in the organs (100%). The distribution of zoonotic diseases varied with the infected organ and the locality of origin of the slaughtered pigs. In order to limit the risk of transmission of zoonoses, systematic health inspections must be carried out by veterinary services to prevent possible public health problems

    Evidence for the Higgs-boson Yukawa coupling to tau leptons with the ATLAS detector

    Get PDF
    Results of a search for H → τ τ decays are presented, based on the full set of proton-proton collision data recorded by the ATLAS experiment at the LHC during 2011 and 2012. The data correspond to integrated luminosities of 4.5 fb−1 and 20.3 fb−1 at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV respectively. All combinations of leptonic (τ → `νν¯ with ` = e, µ) and hadronic (τ → hadrons ν) tau decays are considered. An excess of events over the expected background from other Standard Model processes is found with an observed (expected) significance of 4.5 (3.4) standard deviations. This excess provides evidence for the direct coupling of the recently discovered Higgs boson to fermions. The measured signal strength, normalised to the Standard Model expectation, of µ = 1.43 +0.43 −0.37 is consistent with the predicted Yukawa coupling strength in the Standard Model

    Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS

    Get PDF
    Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations

    Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at s√=8 TeV with the ATLAS detector

    Get PDF
    The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy s√=8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb−1. No significant excess above the Standard Model expectation is observed. Limits are set on supersymmetric particle masses for various supersymmetric models. Depending on the model, the search excludes gluino masses up to 1.32 TeV and squark masses up to 840 GeV. Limits are also set on the parameters of a minimal universal extra dimension model, excluding a compactification radius of 1/R c = 950 GeV for a cut-off scale times radius (ΛR c) of approximately 30

    Measurement of the production of a W boson in association with a charm quark in pp collisions at √s = 7 TeV with the ATLAS detector

    Get PDF
    The production of a W boson in association with a single charm quark is studied using 4.6 fb−1 of pp collision data at s√ = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson decays to an electron or muon, the charm quark is tagged either by its semileptonic decay to a muon or by the presence of a charmed meson. The integrated and differential cross sections as a function of the pseudorapidity of the lepton from the W-boson decay are measured. Results are compared to the predictions of next-to-leading-order QCD calculations obtained from various parton distribution function parameterisations. The ratio of the strange-to-down sea-quark distributions is determined to be 0.96+0.26−0.30 at Q 2 = 1.9 GeV2, which supports the hypothesis of an SU(3)-symmetric composition of the light-quark sea. Additionally, the cross-section ratio σ(W + +c¯¯)/σ(W − + c) is compared to the predictions obtained using parton distribution function parameterisations with different assumptions about the s−s¯¯¯ quark asymmetry

    Search for pair-produced long-lived neutral particles decaying to jets in the ATLAS hadronic calorimeter in ppcollisions at √s=8TeV

    Get PDF
    The ATLAS detector at the Large Hadron Collider at CERN is used to search for the decay of a scalar boson to a pair of long-lived particles, neutral under the Standard Model gauge group, in 20.3fb−1of data collected in proton–proton collisions at √s=8TeV. This search is sensitive to long-lived particles that decay to Standard Model particles producing jets at the outer edge of the ATLAS electromagnetic calorimeter or inside the hadronic calorimeter. No significant excess of events is observed. Limits are reported on the product of the scalar boson production cross section times branching ratio into long-lived neutral particles as a function of the proper lifetime of the particles. Limits are reported for boson masses from 100 GeVto 900 GeV, and a long-lived neutral particle mass from 10 GeVto 150 GeV

    Search for squarks and gluinos with the ATLAS detector in final states with jets and missing transverse momentum using √s=8 TeV proton-proton collision data

    Get PDF
    A search for squarks and gluinos in final states containing high-p T jets, missing transverse momentum and no electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in s√=8 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated luminosity of 20.3 fb−1. Results are interpreted in a variety of simplified and specific supersymmetry-breaking models assuming that R-parity is conserved and that the lightest neutralino is the lightest supersymmetric particle. An exclusion limit at the 95% confidence level on the mass of the gluino is set at 1330 GeV for a simplified model incorporating only a gluino and the lightest neutralino. For a simplified model involving the strong production of first- and second-generation squarks, squark masses below 850 GeV (440 GeV) are excluded for a massless lightest neutralino, assuming mass degenerate (single light-flavour) squarks. In mSUGRA/CMSSM models with tan β = 30, A 0 = −2m 0 and μ > 0, squarks and gluinos of equal mass are excluded for masses below 1700 GeV. Additional limits are set for non-universal Higgs mass models with gaugino mediation and for simplified models involving the pair production of gluinos, each decaying to a top squark and a top quark, with the top squark decaying to a charm quark and a neutralino. These limits extend the region of supersymmetric parameter space excluded by previous searches with the ATLAS detector
