The effects of scent on consumer behaviour
Authors: Rimkute Justina , Moraes Caroline , Ferreira Carlos 
Published: May 2015

AbstractThis article presents a systematic review of extant research on the effects of scent on consumer behaviour for readers of the International Journal of Consumer Studies. Although many articles have been published on this topic in recent years, there is a need for a comprehensive summary of up‐to‐date findings in this area of research. A systematic literature review is conducted with selected Chartered Association of Business Schools‐ranked journals in the fields of marketing and psychology, covering the period between 1980 and 2015. Thematic areas include the impact of scent on consumers’ cognitive and affective responses, attitudes and perceptions, as well as memory and behaviours. Relevant mediators and moderators of the effects of scent on these variables include affect, cognition, awareness and individual or environmental stimuli. Gaps for future research are identified and include the role of consumer awareness of scent and its influence on behaviour. Although this article provides a systematic review of the literature within the fields of psychology and marketing, it acknowledges that a large body of research regarding human responses to odours exists within other disciplinary fields such as neuroscience. The potential for, as well as the ethical caveats of, using scent stimuli for marketing purposes are also considered. This article makes a significant contribution to the consumer behaviour literature given its systematic article selection and review process, encompassing the most up‐to‐date research and focusing on all key thematic areas related to scent and consumption.

AbstractQuality of life of the future generations depends on the efforts of current generations to protect environment. The purchase decisions based on their green behavioral intentions not only helps the society, but also helps companies to gain a green competitive advantage. In this study, the relationships between green satisfaction, green trust, green equity and behavioral intentions are examined. Data were collected from Turkey, Finland and Pakistan with self‐administered questionnaires regarding with green white goods. The hypotheses were tested with structural equation modeling. Results of a structural model reveal positive relationships green satisfaction, green trust and green brand equity across three countries. In addition, green brand equity plays a remarkable role in behavioral intentions towards green white goods in general. Managers should consider green trust, green satisfaction, and green brand equity while implementing green marketing strategies in a global marketplace.
Why buy organic rice? genetic algorithm‐based fuzzy association mining rules for means‐end chain data

AbstractWhile empirical studies of organic food consumption have centred primarily on European and North American countries, the amount of research occurring in Asian countries is increasing. This article describes the attributes, consequences, and values influencing consumer perceptions and adoption of organic rice in Taiwan, where rice is the major food. Based on a means‐end chain (MEC) rationale, regulatory focus theory and self‐construal theory, this article describes the attributes, consequences and values influencing Taiwanese consumer perceptions and adoption of organic rice. Using a questionnaire and a sample of 300 organic food shoppers in Taiwan, we applied the MEC technique in a different fashion via the proposed genetic algorithm‐based fuzzy association mining rules (GFAMR) algorithm to depict the attribute‐consequence‐value links to purchasing organic rice. This study has at least two merits: (a) it is among the first integrating regulatory focus theory, self‐construal theory and MEC to explore the reason why Taiwanese consumers purchase organic rice and (b) it introduces a new method to quantitatively deal with MEC analysis. The results show that the most important ultimate values are fun and enjoyment in life and security, which are in line with the promotion focus and prevention focus, respectively, of regulatory focus theory. Furthermore, we found three consumer segments related to organic rice: prevention focused housekeepers, promotion‐focused egoists, and promotion‐focused (meta‐personal self) altruists. The different paths found in the results can also provide green companies and policy makers with more information about organic rice consumers, allowing them to craft better marketing and communication strategies by which to promote organic food.

Published: May 2015

SummaryThe influence of the extraction system (continuous vs. discontinuous) and the degree of freshness of olives on the chemical composition and the quality of Chemlali and Chétoui virgin olive oil has been studied. Analytical data mainly concerning the volatile and sensory profiles revealed statistically significant differences in relation to the extraction system. All quality indices and sensory characteristics showed statistically significant differences associated with the degree of freshness of fruits. These results further confirm the general consensus that volatile compounds can be very useful as biomarkers of the quality of virgin olive oil and show correlations with the sensory characteristics.

Published: May 2015

SummaryQuinoa is a highly appreciated Andean pseudo‐cereal and has sparked attention worldwide due to its excellent nutritional value. The protein extraction parameters for defatted quinoa seed meal (DQSM) were optimised in this study. Initially, a Plackett–Burman design was applied to screen the factors displaying a potential effect on the quinoa protein extraction yield (Y %, g soluble protein/100 g total protein) being the main evaluated factors: pH, NaCl concentration, time, temperature, solvent type, particle size and solvent/meal ratio. Four main factors: temperature, solvent/meal ratio, pH and time selected from the screening step were optimised with a central composed design (CCD). The obtained response surface model (RSM) produced a satisfactory fitting of the results (R2 = 0.9308). Optimal quinoa protein extraction conditions of 36.2 °C, solvent/meal ratio of 19.6/1 (v/w) and 90 min resulted in a protein yield of 62.1% (9.06 g of protein/100 g DQSM) which closely agree with the predicted value of 62.5%.The model was experimentally validated by extracting the quinoa protein using the optimal conditions revealed by RSM. The optimised conditions could be successfully employed in the design process of protein extraction from quinoa seed meal to obtain optimal yields.
Chilling prior to low intensity pulsed electric field processing improved vitamin C stability of carrot purée (Daucus carota cv. Nantes)

Published: May 2015

SummaryEffects of chilling (5 °C) prior to low intensity pulsed electric fields (PEF) (0.1–1.1 kV cm−1) on vitamin C and activity of peroxidase (POD) and ascorbic acid oxidase (AAO) in carrot purée were studied. The effect of PEF on carotenoids extractability was evaluated and compared to that of purée pre‐conditioned at 20 °C (control). PEF enhanced carotenoids extractability for purée with and without pre‐chilling, up to 25% and 66%, respectively. Vitamin C content decreased after PEF but combined pre‐chilling and PEF maintained vitamin C stability and reduced AAO and POD activities. AAO and the heat‐stable POD fraction were found to be more thermolabile (i.e. higher kref value) after PEF, particularly at 0.6 kV cm−1, which implies elimination of their enzymatic action towards oxidation of bioactive compounds. It was suggested that chilling prior to low intensity PEF modified enzyme properties and secured the stability of vitamin C and carotenoids.

SummaryDengue is a mosquito‐borne disease that affects millions of people worldwide yearly. Currently, there is no vaccine or specific treatment available. Further investigation on dengue pathogenesis is required to better understand the disease and to identify potential therapeutic targets. The chemokine system has been implicated in dengue pathogenesis, although the specific role of chemokines and their receptors remains elusive. Here we describe the role of the CC‐chemokine receptor CCR5 in Dengue virus (DENV‐2) infection. In vitro experiments showed that CCR5 is a host factor required for DENV‐2 replication in human and mouse macrophages. DENV‐2 infection induces the expression of CCR5 ligands. Incubation with an antagonist prevents CCR5 activation and reduces DENV‐2 positive‐stranded (+) RNA inside macrophages. Using an immunocompetent mouse model of DENV‐2 infection we found that CCR5−/− mice were resistant to lethal infection, presenting at least 100‐fold reduction of viral load in target organs and significant reduction in disease severity. This phenotype was reproduced in wild‐type mice treated with CCR5‐blocking compounds. Therefore, CCR5 is a host factor required for DENV‐2 replication and disease development. Targeting CCR5 might represent a therapeutic strategy for dengue fever. These data bring new insights on the association between viral infections and the chemokine receptor CCR5.
Periodic review fuzzy inventory model with variable lead time and fuzzy demand

Published: May 2015

AbstractThis paper investigates a periodic review fuzzy inventory model with lead time, reorder point, and cycle length as decision variables. The main goal of this study is to minimize the expected total annual cost by simultaneously optimizing cycle length, reorder point, and lead time for the whole system based on fuzzy demand. Two models are considered in this paper: one with normal demand distribution and another with a distribution‐free approach. The model assumes a logarithmic investment function for lost‐sale rate reduction. Furthermore, two separate efficient computational algorithms are explained to obtain the optimal solution. Some numerical examples are given to illustrate the model.
Similar patterns of frequency‐dependent selection on animal personalities emerge in three species of social spiders
Authors: Lichtenstein J. L. L. , Pruitt J. N. 
Published: May 2015

AbstractFrequency‐dependent selection is thought to be a major contributor to the maintenance of phenotypic variation. We tested for frequency‐dependent selection on contrasting behavioural strategies, termed here ‘personalities’, in three species of social spiders, each thought to represent an independent evolutionary origin of sociality. The evolution of sociality in the spider genus Anelosimus is consistently met with the emergence of two temporally stable discrete personality types: an ‘aggressive’ or ‘docile’ form. We assessed how the foraging success of each phenotype changes as a function of its representation within a colony. We did this by creating experimental colonies of various compositions (six aggressives, three aggressives and three dociles, one aggressive and five dociles, six dociles), maintaining them in a common garden for 3 weeks, and tracking the mass gained by individuals of either phenotype. We found that both the docile and aggressive phenotypes experienced their greatest mass gain in mixed colonies of mostly docile individuals. However, the performance of both phenotypes decreased as the frequency of the aggressive phenotype increased. Nearly identical patterns of phenotype‐specific frequency dependence were recovered in all three species. Naturally occurring colonies of these spiders exhibit mixtures dominated by the docile phenotype, suggesting that these spiders may have evolved mechanisms to maintain the compositions that maximize the success of the colony without compromising the expected reproductive output of either phenotype.

AbstractWe designed a single nucleotide primer extension (SNaPshot) assay for Pneumocystis jirovecii genotyping, targeting mt85 SNP of the mitochondrial large subunit ribosomal RNA locus, to improve minority allele detection. We then analyzed 133 consecutive bronchoalveolar lavage (BAL) fluids tested positive for P. jirovecii DNA by quantitative real‐time PCR, obtained from two hospitals in different locations (Hospital 1 [n = 95] and Hospital 2 [n = 38]). We detected three different alleles, either singly (mt85C: 39.1%; mt85T: 24.1%; mt85A: 9.8%) or together (27%), and an association between P. jirovecii mt85 genotype and the patient's place of hospitalization (p = 0.011). The lowest fungal loads (median = 0.82 × 103 copies/μl; range: 15–11 × 103) were associated with mt85A and the highest (median = 1.4 × 106 copies/μl; range: 17 × 103–1.3 × 107) with mt85CTA (p = 0.010). The ratios of the various alleles differed between the 36 mixed‐genotype samples. In tests of serial BALs (median: 20 d; range 4–525) from six patients with mixed genotypes, allele ratio changes were observed five times and genotype replacement once. Therefore, allele ratio changes seem more frequent than genotype replacement when using a SNaPshot assay more sensitive for detecting minority alleles than Sanger sequencing. Moreover, because microscopy detects only high fungal loads, the selection of microscopy‐positive samples may miss genotypes associated with low loads.
Goods Movement Life Cycle Assessment for Greenhouse Gas Reduction Goals

Published: May 2015

SummaryThe formation of effective policies to reduce emissions from goods movement should consider local and remote life cycle effects as well as barriers for mode shifting. Using uni‐ and multimodal freight movements by truck, rail, and ocean‐going vessel (OGV) associated with California, a life cycle assessment (LCA) is developed to estimate the local and remote emissions that occur from freight activity inside and associated with the state. Long‐run average per tonne‐kilometer results show that OGVs emit the fewest emissions, followed by rail, then trucks, and that the inclusion of life cycle processes can increase impacts by up to 32% for energy and greenhouse gas (GHG) emissions and 4,200% for conventional air pollutants. Efforts to reduce emissions through mode shifting should recognize that infrastructure and market configurations may be inimical to mode substitution. A uni‐ and multimodal shipping emissions assessment is developed for intrastate and California‐associated freight movements to illustrate the life cycle impacts of typical trips for certain types of goods. When targeting GHG reductions in California, it should be recognized that heavy‐duty trucks are responsible for 99% of intrastate goods movement emissions. An assessment of future freight truck technology improvements is performed to estimate the effectiveness of strategies to meet 2050 GHG reduction goals. Whereas aggressive improvements in fuel economy coupled with alternative vehicles and fuels can significantly reduce GHG emissions, to meet 2050 goals will likely require zero carbon emission vehicle technology. The value of using LCA in GHG reduction policy for transportation systems is explored.

AbstractDopaminergic neurons of the central nervous system are mainly found in nuclei of the midbrain and the hypothalamus that provide subcortical and cortical targets with a rich and divergent innervation. Disturbance of signaling through this system underlies a variety of deteriorating conditions such as Parkinson's disease and schizophrenia. Although retinal dopaminergic signaling is largely independent of the above circuitry, malfunction of the retinal dopaminergic system has been associated with anomalies in visual adaptation and a number of retinal disorders. Dopamine (DA) is released mainly in a paracrine manner by a population of tyrosine hydroxylase expressing (TH+) amacrine cells (AC) of the mammalian retina; thus DA reaches virtually all retinal cell types by diffusion. Despite this paracrine release, however, the so called AII ACs have been considered as the main targets of DA signaling owing to a characteristic and robust ring‐like TH+ innervation to the soma/dendritic‐stalk area of AII cells. This apparent selectivity of TH+ innervation seems to contradict the divergent DAergic signaling scheme of other brain loci. In this study, however, we show evidence for intimate proximity between TH+ rings and somata of neurochemically identified non‐AII cells. We also show that this phenomenon is not species specific, as we observe it in popular mammalian animal models including the rabbit, the rat, and the mouse. Finally, our dataset suggests the existence of further, yet unidentified post‐synaptic targets of TH+ dendritic rings. Therefore, we hypothesize that TH+ ring‐like structures target the majority of ACs non‐selectively and that such contacts are wide‐spread among mammals. Therefore, this new view of inner retinal TH+ innervation resembles the divergent DAergic innervation of other brain areas through the mesolimbic, mesocortical, and mesostriatal signaling streams.
imageAII amacrine cells have been considered as the main targets of dopamine signaling in the mammalian retina owing to a characteristic ring‐like innervation from dopaminergic (TH+) amacrine cells (green) to somata of AII cells (red). In this study, we show the intimate proximity of TH+ rings and somata of non‐AII cells, including starburst‐a amacrine cells (blue) and other unidentified amacrine cells (magenta). We find that this phenomenon is not species specific and it occurs in a number of popular mammalian animal models. We hypothesize that TH+ ring‐inputs target most amacrine cells non‐selectively and thus it resembles the divergent dopaminergic innervation of other brain areas.
Failures in communication through documents and documentation across the perioperative pathway

Published: May 2015

Aims and objectivesTo explore how communication failures occur in documents and documentations across the perioperative pathway in nurses' interactions with other nurses, surgeons and anaesthetists.BackgroundDocuments and documentation are used to communicate vital patient and procedural information among nurses, and in nurses' interactions with surgeons and anaesthetists, across the perioperative pathway. Previous research indicates that communication failure regularly occurs in the perioperative setting.DesignA qualitative study was undertaken.MethodsThe study was conducted over three hospitals in Melbourne, Australia. One hundred and twenty‐five healthcare professionals from the disciplines of surgery, anaesthesia and nursing participated in the study. Data collection commenced in January 2010 and concluded in October 2010. Data were generated through 350 hours of observation, two focus groups and 20 semi‐structured interviews. A detailed thematic analysis was undertaken.ResultsCommunication failure occurred owing to a reliance on documents and documentation to transfer information at patient transition points, poor quality documents and documentation, and problematic access to information. Institutional ruling practices of professional practice, efficiency and productivity, and fiscal constraint dominated the coordination of nurses', surgeons' and anaesthetists' communication through documents and documentation. These governing practices configured communication to be incongruous with reliably meeting safety and quality objectives.ConclusionsCommunication failure occurred because important information was sometimes buried in documents, insufficient, inaccurate, out‐of‐date or not verbally reinforced. Furthermore, busy nurses were not always able to access information they required in a timely manner. Patient safety was affected, which led to delays in treatment and at times inadequate care.Relevance to clinical practiceOrganisational support needs to be provided to nurses, surgeons and anaesthetists so they have sufficient time to complete, locate, and read documents and documentation. Infrastructure supporting communication technologies should be implemented to enable the rapid retrieval, entry, and dispersion of information.
Asymmetric Information about Collateral Values
Authors: STROEBEL JOHANNES 
Published: May 2015

ABSTRACTI empirically analyze credit market outcomes when competing lenders are differentially informed about the expected return from making a loan. I study the residential mortgage market, where property developers often cooperate with vertically integrated mortgage lenders to offer financing to buyers of new homes. I show that these integrated lenders have superior information about the construction quality of individual homes and exploit this information to lend against higher quality collateral, decreasing foreclosures by up to 40%. To compensate for this adverse selection on collateral quality, nonintegrated lenders charge higher interest rates when competing against a better‐informed integrated lender.
