An investigation of the retail marketing mix and its effectiveness in small shops

The recent history of small shop and independent retailing has been one of decline. The most desirable form of assistance is the provision of information which will increase the efficiency model of marketing mix effeciveness which may be applied in small scale retailing. A further aim is to enhance theoretical development in the marketing field. Recent changes in retailing have affected location, product range, pricing and promotion practices. Although a large number of variables representing aspects of the marketing mix may be identified, it is not possible, on the basis of currently available information, to quantify or rank them according to their effect on sales performance. In designing a suitable study a major issue is that of access to a suitable representative sample of small retailers. The publish nature of the retail activities involved facilitates the use of a novel observation approach to data collection. A cross-sectional survey research design was used focussing on a clustered random sample of greengrocers and gent's fashion outfitters in the West Midlands. Linear multiple regression was the main analytical technique. Powerful regression models were evolved for both types of retailing. For greengrocers the major influences on trade are pedestrian traffic and shelf display space. For gent's outfitters they are centrality-to-other shopping, advertising and shelf display space. The models may be utilised by retailers to determine the relative strength of marketing mix variables. The level of precision is not sufficient to permit cost benefit analysis. Comparison of the findings for the two distinct kinds of business studied suggests an overall model of marketing mix effectiveness might be based on frequency of purchase, homogeneity of the shopping environment, elasticity of demand and bulk characteristics of the good sold by a shop.

From 'perfect mix' to 'potion magique':regulatory T cells and anti-inflammatory cytokines as adjuvant targets

The efficacy of vaccines can be greatly improved by the addition of adjuvants, which enhance and modify immune responses. Historically, adjuvants have been discovered empirically by using experimental models.

Supercritical carbonation of calcareous composites:influence of mix design

This work combined compression moulding with subsequent super-critical carbonation treatment (100 bar, 60 °C, 24 h) to fabricate cement and/or lime based ceramic composites with various aggregates. Composites were examined using mechanical testing, XRD, He pycnometry and thin-section petrography. Composites with lime-only binders were significantly weaker than those with cement-lime binders regardless of the degree of carbonation. Flexural strengths in excess of >10 MPa were routinely achieved in large (>100 mm) specimens. Aggregate type (calcareous vs. siliceous) had a significant effect on the microstructure and properties of the composites. Calcareous aggregates appear to augment the strength enhancement effected during super-critical carbonation by encouraging preferential precipitation of calcite at the binder-aggregate interface.

Improved methodology to evaluate fracture properties of warm-mix asphalt using overlay test

This study developed a reliable and repeatable methodology to evaluate the fracture properties of asphalt mixtures with an overlay test (OT). In the proposed methodology, first, a two-step OT protocol was used to characterize the undamaged and damaged behaviors of asphalt mixtures. Second, a new methodology combining the mechanical analysis of viscoelastic force equilibrium in the OT specimen and finite element simulations was used to determine the undamaged properties and crack growth function of asphalt mixtures. Third, a modified Paris's law replacing the stress intensity factor by the pseudo J-integral was employed to characterize the fracture behavior of asphalt mixtures. Theoretical equations were derived to calculate the parameters A and n (defined as the fracture properties) in the modified Paris's law. The study used a detailed example to calculate A and n from the OT data. The proposed methodology was successfully applied to evaluate the impact of warm-mix asphalt (WMA) technologies on fracture properties. The results of the tested specimens showed that Evotherm WMA technology slightly improved the cracking resistance of asphalt mixtures, while foaming WMA technology provided comparable fracture properties. In addition, the study found that A decreased with the increase in n in general. A linear relationship between 2log(A) and n was established.

Replacing Place In Marketing-Mix Strategy For Hospitality Services

In the conventional marketing mix, a focus on physical distribution handicaps the use of "place" in planning marketing strategy for hospitality services. To replace it, the article introduces a new group of variables called "performance," which focus instead on availability and accessibility. The author does not intend to offer detailed descriptions of specific variables but rather to suggest associations and relationships among issues and options in marketing hospitality services that may not previously have been recognized, and to address the diverse segments of the hospitality services industry in general, including lodging, food, beverage, private club, cruise ship, and travel-destination services.

Ottimizzazione di mix design di geopolimeri a base di metacaolino e studio dei relativi processi di formatura

Il seguente lavoro di tesi si pone come obiettivo di ottimizzare il mix design di materiali geopolimerici a base di metacaolino in modo da ottimizzare il procedimento di formatura tramite pressatura tipico delle piastrelle ceramiche. La parte iniziale del lavoro sperimentale è stata incentrata sullo studio dell’ottimizzazione delle formulazioni per ottenere impasti geopolimerici a base di metacaolino idonei per la pressatura e il colaggio; sono stati quindi preparate diverse formulazioni ottenute variando diversi parametri di processo, quali il contenuto totale di acqua dell’impasto e la concentrazione di quarzo utilizzato come filler inerte. Su tali mix è stato individuato il processo di formatura più idoneo dal punto di vista di temperatura di consolidamento, modalità e tempi di cottura ed è stato messo a punto il procedimento ottimale per la preparazione dei materiali, procedimento che è stato poi mantenuto per l’intero decorso dello studio. Nella produzione degli impasti si è deciso di eliminare sistematicamente quelle formulazioni che avevano prodotto materiali con peggiori prestazioni fisiche, come alcune formulazioni testate per il colaggio. Successivamente, dopo avere preparato i campioni, su di essi sono state eseguite le prove di assorbimento d’acqua e porosimetria ad intrusione di mercurio, per valutare le caratteristiche fisiche dei vari impasti prodotti, osservazioni al microscopio ottico e al microscopio a scansione elettronica, per analizzare i campioni selezionati dal punto di vista microstrutturale e morfologico e prove al microscopio riscaldante, per studiarne il comportamento alle alte temperature. I risultati ottenuti sono stati messi a confronto con quelli dei materiali ceramici tradizionali, per avere indicazioni sulla potenzialità dei prodotti a base geopolimerica come alternativa alla produzione di piastrelle ceramiche.

Investigation on performance characteristics of dense graded hot mix asphalt with RAP and crumb rubber

The objective of this study was to fundamentally characterize the laboratory performance of traditional hot mix asphalt (HMA) mixtures incorporating high RAP content and waste tire crumb rubber through their fundamental engineering properties. The nominal maximum aggregates size was chosen for this research was 12mm (considering the limitation of aggregate size for surface layer) and both coarse and fine aggregates are commonly used in Italy that were examined and analyzed in this study. On the other hand, the RAP plays an important role in reducing production costs and enhancing the environmentally sustainable pavements instead of using virgin materials in HMA. Particularly, this study has aimed to use 30% of RAP content (25% fine aggregate RAP and 5% coarse aggregate RAP) and 1% of CR additives by the total weight of aggregates for mix design. The mixture of aggregates, RAP and CR were blended with different amount of unmodified binder through dry processes. Generally, the main purposes of this study were investigating on capability of using RAP and CR in dense graded HMA and comparing the performance of rejuvenator in RAP with CR. In addition, based on the engineering analyses during the study, we were able compare the fundamental Indirect Tensile Strength (ITS) value of dense graded HMA and also mechanical characteristics in terms of Indirect Tensile Stiffness Modulus (ITSM). In order to get an extended comparable data, four groups of different mixtures such as conventional mixture with only virgin aggregates (DV), mixture with RAP (DR), mixture with RAP and rejuvenator (DRR), and mixture with RAP, rejuvenator, CR (DRRCr) were investigated in this research experimentally. Finally, the results of those tests indicated that the mixtures with RAP and CR had the high stiffness and less thermal sensitivity, while the mixture with virgin aggregates only had very low values in comparison.

Validation of Gyratory Mix Design in Iowa, TR-667, 2016

The design number of gyrations (Ndesign) introduced by the Strategic Highway Research Program (SHRP) and used in the Superior Performing Asphalt Pavement (Superpave) mix design method has been commonly used in flexible pavement design throughout the US since 1996. Ndesign, also known as the compaction effort, is used to simulate field compaction during construction and has been reported to produce air voids that are unable to reach ultimate pavement density within the initial 2 to 3 years post-construction, potentially having an adverse impact on long-term performance. Other state transportation agencies have conducted studies validating the Ndesign for their specific regions, which resulted in modifications of the gyration effort for the various traffic levels. Validating this relationship for Iowa asphalt mix designs will lead to better correlations between mix design target voids, field voids, and performance. A comprehensive analysis of current Ndesign levels investigated the current levels with existing mixes and pavements and developed initial asphalt mix design recommendations that identify an optimum Ndesign through the use of performance data tests.

Präsenzunterricht, Fernunterricht: Die Suche nach dem optimalen Mix

Bei der Beurteilung von Projekten des Swiss Virtual Campus (SVC; Virtueller Campus Schweiz, Campus Virtuel Suisse, Campus Virtuale Svizzero), eines Programms des Bundes zur Förderung der neuen Informations- und Kommunikationstechnologien in der Hochschullehre, gilt es auch auf den optimalen Mix von Präsenzunterricht und Fernunterricht zu achten. Welche Arten von Szenarien sind vorstellbar, und wie beeinflusst die Art des Szenarios die optimale Verteilung von Präsenz- und Fernunterricht? Welche technischen Hilfsmittel sind für welches Szenario sinnvoll? Der Swiss Virtual Campus ist grundsätzlich nicht als Online-Universität geplant und nicht auf Fernstudien ausgerichtet. Es ist jedoch denkbar, dass manche Projekte des Swiss Virtual Campus künftig den Weg in Fernstudienangebote finden werden, obwohl sie nicht dafür konzipiert wurden. Einige Projekte von Fachhochschulen wurden bereits als Fernstudium konzipiert. In gewissen Aspekten funktionieren sie nach anderen Regeln als für Präsenzunterricht konzipierte Kurse.(DIPF/Orig.)

Inclusion of cottonseed meal into loose mineral mix supplements increases the voluntary intake of the supplement by grazing heifers

Loose mineral mix (LMM) supplements based on ingredients such as salt, urea and minerals offered ad libitum are widely used to provide additional nutrients to grazing cattle, but it is often difficult to achieve target intakes. An experiment with heifers grazing mature tropical pasture examined the effects of substituting 80, 160 or 320 g/kg of the salt in a LMM supplement with cottonseed meal on the voluntary intake of the LMM supplements by paddock groups of heifers over 10 weeks. Average voluntary intake of a LMM containing (g/kg) 640 salt, 300 urea and 60 ammonium sulfate (40.2 g DM and 6.14 g total nitrogen/day) was increased linearly (P < 0.001) to 50.8 g DM and 8.88 g total nitrogen/day when up to 320 g/kg cottonseed meal was substituted for salt in the LMM. This increase in intake of nitrogen in LMM was due to the increase in voluntary intake of the supplement rather than the increased nitrogen concentration of supplement. The distribution of daily intake of supplement within paddock groups of heifers was estimated during Weeks 5 and 10 using supplements labelled with lithium sulfate. Neither the coefficient of variation within paddock groups of heifers in supplement intake (mean 96%), nor the proportion of non-consumers of supplement (mean 17%), was changed (P > 0.05) by substitution of salt with cottonseed meal. In conclusion, the inclusion of a palatable protein meal into LMM increased the voluntary intake of this type of supplement.
