    Full Text Available The authors describe the first case of parasitism on anuran amphibian, Rana temporaria, by the freshwater leech Helobdella stagnalis, in a mountainous area of northwestern Italy. The presence of skin abrasions and haemorrhages attributable to leech attack discards the hypothesis of a simple phoretic relationship between leech and frog.

    Bone morphogenetic protein (BMP) signaling is broadly implicated in dorsoventral (DV) patterning of bilaterally symmetric animals [1-3], and its role in axial patterning apparently predates the birth of Bilateria [4-7]. In fly and vertebrate embryos, BMPs and their antagonists (primarily Sog/chordin) diffuse and interact to generate signaling gradients that pattern fields of cells [8-10]. Work in other species reveals diversity in essential facets of this ancient patterning process, however. Here, we report that BMP signaling patterns the DV axis of segmental ectoderm in the leech Helobdella, a clitellate annelid (superphylum Lophotrochozoa) featuring stereotyped developmental cell lineages, but the detailed mechanisms of DV patterning in Helobdella differ markedly from fly and vertebrates. In Helobdella, BMP2/4s are expressed broadly, rather than in dorsal territory, whereas a dorsally expressed BMP5-8 specifies dorsal fate by short-range signaling. A BMP antagonist, gremlin, is upregulated by BMP5-8 in dorsolateral, rather than ventral territory, and yet the BMP-antagonizing activity of gremlin is required for normal ventral cell fates. Gremlin promotes ventral fates without disrupting dorsal fates by selectively inhibiting BMP2/4s, not BMP5-8. Thus, DV patterning in the development of the leech revealed unexpected evolutionary plasticity of the conserved BMP patterning system, presumably reflecting its adaptation to different modes of embryogenesis.

    Full Text Available A new freshwater leech species Helobdella fantasmae n. sp. is described. This description is based on the examination of 12 specimens collected in Laguna Fantasma, Bariloche (41° 05'S 71° 28'W, during December 2002. Leeches were found attached to submerged plants. They were relaxed with gradual addition of 70% ethanol, fixed in 10% formalin, stored in 70% ethanol and stained with borax carmine. Examination of external morphology, dissections and microphotographs were accomplished with a Leica Wild M3Z stereo microscope aided with an Olympus C-4000 digital camera. H. fantasmae n. sp. differs from other species of the genus by the presence of 1 pair of eyes on somite III, crop without gastric chambers, digitiform caeca and postcaeca., short sperm ducts reaching the back of somite XV, atrium pyriform, short ovisacs reaching somite XIII. This is the first record of leeches from an ephemeral wetland in North Patagonia. This finding expands current knowledge of the biodiversity of Hirudinea in South America, increasing the number of known Helobdella spp. from the Río Negro province (North Patagonia to 10 species.Se describe una especie de sanguijuela dulceacuícola Helobdella fantasmae n. sp.

    Phytochelatins are metal-binding metabolites found in almost all plant species and some animal groups, including nematodes and annelids, where they can play an important role in detoxifying metals such as cadmium. Species from several other taxa contain a phytochelatin synthase (PCS) gene orthologue, including molluscs, indicating they may have the potential to synthesize phytochelatins. However, the presence of a gene alone does not demonstrate that it plays a functional role in metal detoxification. In the present study, we show that the aquatic snail Lymnaea stagnalis produced both penta- and heptapeptide phytochelatins (i.e. phytochelatin-2 and phytochelatin-3), and their levels increased in response to sub-lethal levels of cadmium. - Highlights: • Little is known about the role of phytochelatins in metal detoxification in animals. • We detected phytochelatins (PC{sub 2} and PC{sub 3}) in a mollusc species, Lymnaea stagnalis. • Phytochelatins increased in Lymnaea stagnalis when exposed to cadmium. • Future research on phytochelatin responses in molluscs would be valuable.

    laboratories in Denmark, Germany and the UK for the OECD pre-validation work to date. Laboratory cultures of L. stagnalis are traditionally fed fresh (preferably organic) lettuce; however, interrupted supplies of fresh lettuce in some countries in 2011 highlighted a potential problem for the draft OECD test...... of a mollusc reproduction test guideline. An ad hoc mollusc expert group has been formed in Europe to validate methods that can meet this need. Currently, a key species for use in this context is the freshwater gastropod Lymnaea stagnalis. An important aspect of this work is to first develop a specific...... pathogen free defined strain of L. stagnalis and second to establish a historical database of growth and reproductive rates under defined culturing conditions.

    This paper presents the results from two ring-tests addressing the feasibility, robustness and reproducibility of a reproduction toxicity test with the freshwater gastropod Lymnaea stagnalis (RENILYS strain). Sixteen laboratories (from inexperienced to expert laboratories in mollusc testing) from nine countries participated in these ring-tests. Survival and reproduction were evaluated in L. stagnalis exposed to cadmium, tributyltin, prochloraz and trenbolone according to an OECD draft Test Guideline. In total, 49 datasets were analysed to assess the practicability of the proposed experimental protocol, and to estimate the between-laboratory reproducibility of toxicity endpoint values. The statistical analysis of count data (number of clutches or eggs per individual-day) leading to ECx estimation was specifically developed and automated through a free web-interface. Based on a complementary statistical analysis, the optimal test duration was established and the most sensitive and cost-effective reproduction toxicity endpoint was identified, to be used as the core endpoint. This validation process and the resulting optimized protocol were used to consolidate the OECD Test Guideline for the evaluation of reproductive effects of chemicals in L. stagnalis.

    In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle. Here, we have used germ line markers (piwi, vasa, and nanos) and microinjected cell lineage tracers to show that PGC specification in the leech genus Helobdella follows a different scenario: in this hermaphrodite, the male and female PGCs segregate from somatic lineages only after more than 20 rounds of zygotic mitosis; the male and female PGCs share the same (mesodermal) cell lineage for 19 rounds of zygotic mitosis. Moreover, while all three markers are expressed in both male and female reproductive tissues of the adult, they are expressed differentially between the male and female PGCs of the developing embryo: piwi and vasa are expressed preferentially in female PGCs at a time when nanos is expressed preferentially in male PGCs. A priori, the delayed segregation of male and female PGCs from somatic tissues and from one another increases the probability of mutations affecting both male and female PGCs of a given individual. We speculate that this suite of features, combined with a capacity for self-fertilization, may contribute to the dramatically rearranged genome of Helobdella robusta relative to other animals.

  10. Chemosensitivity of the osphradium of the pond snail Lymnaea stagnalis

    1995-01-01

    The osphradium of the pond snail Lymnaea stagnalis was studied to determine the stimuli to which this organ responds. The following stimuli were tested: hypoxia, hypercapnia, a mixture of amino acids, a mixture of citralva and amyl acetate and a mixture of lyral, lilial and ethylvanillin. The mean nerve activity consistently increased with elevated PCO2, whereas hypoxia produced variable effects. The nerve activity became rhythmic upon application of citralva and amyl acetate, but it increased in a non-rhythmic way upon application of the other two odorant mixtures tested. Whole-cell patch-clamp recordings were made from a group of 15 neurones that lay next to the issuing osphradial nerve, to determine whether ganglion cells were involved in olfactory signal processing. All neurones tested responded to at least one of the three mixtures of odorants. Both excitatory and inhibitory responses occurred. Our results indicate that the osphradium of the pond snail Lymnaea stagnalis is sensitive to elevated PCO2 as well as to three different classes of odorants. In addition, at least some neurones within the osphradium are involved in the processing of olfactory information.

  11. Assessment of anoxia tolerance and photoperiod dependence of GABAergic polarity in the pond snail Lymnaea stagnalis.

    The pond snail Lymnaea stagnalis is reported to be anoxia-tolerant and if the tolerance mechanism is similar to that of the anoxia-tolerant painted turtle, GABA should play an important role. A potentially confounding factor investigating the role of GABA in anoxia tolerance are reports that GABA has both inhibitory and excitatory effects within L. stagnalis central ganglion. We therefore set out to determine if seasonality or photoperiod has an impact on: 1) the anoxia-tolerance of the intact pond snail, and 2) the response of isolated neuroganglia cluster F neurons to exogenous GABA application. L. stagnalis maintained on a natural summer light cycle were unable to survive any period of anoxic exposure, while those maintained on a natural winter light cycle survived a maximum of 4h. Using intracellular sharp electrode recordings from pedal ganglia cluster F neurons we show that there is a photoperiod dependent shift in the response to GABA. Snails exposed to a 16h:8h light:dark cycle in an environmental chamber (induced summer phenotype) exhibited hyperpolarizing inhibitory responses and those exposed to a 8h:16h light:dark cycle (induced winter phenotype) exhibited depolarizing excitatory responses to GABA application. Using gramicidin-perforated patch recordings we also found a photoperiod dependent shift in the reversal potential for GABA. We conclude that the opposing responses of L. stagnalis central neurons to GABA results from a shift in intracellular chloride concentration that is photoperiod dependent and is likely mediated through the relative efficacy of cation chloride co-transporters. Although the physiological ramifications of the photoperiod dependent shift are unknown this work potentially has important implications for the impact of artificial light pollution on animal health.

    It is now becoming clear that the determination of the physico-chemical forms of transuranic elements is an important step in assessing their behaviour at very low environmental levels. Data from both simulated environmental systems as well as in-situ investigations have shown the necessity of understanding the source term of contamination, which probably plays a major role in the long-term distribution of these elements. In the present paper an experimental procedure is outlined, which allows a more extensive investigation into some aspects of the biogeochemical behaviour of two transuranics: 237 Pu and 241 Am. Two chemical methods were applied to a study of the freshwater snail Lymnaea stagnalis L.. Data were obtained on the uptake and retention patterns of different oxidation states of 237 Pu and 241 Am at the organ and cellular levels of the pond snail. An attempt was made to relate the environmental chemistry of both radionuclides to the fixation in L. stagnalis. (author)

    Many studies have reported perturbations of mollusc reproduction following exposure to low concentrations (ng/L range) of endocrine disrupting chemicals (EDCs). However, the mechanisms of action of these molecules on molluscs are still poorly understood. Investigation of the modifications of protein expression in organisms exposed to chemicals using proteomic methods can provide a broader and more comprehensive understanding of adverse impacts of pollution on organisms than conventional biochemical biomarkers (e.g., heat-shock proteins, metallothioneins, GST, EROD). In this study we have investigated the impacts of four chemicals, which exhibit different endocrine disrupting properties in vertebrates, on the proteome of the hermaphroditic freshwater pulmonate gastropod Lymnaea stagnalis after 21 days of exposure. Testosterone, tributyltin, chlordecone and cyproterone acetate were chosen as tested compounds as they can induce adverse effects on the reproduction of this snail. The 2D-DIGE method was used to identify proteins whose expression was affected by these compounds. In addition to modifying the expression of proteins involved in the structure and function of the cytoskeleton, chemicals had impacts on the expression of proteins involved in the reproduction of L. stagnalis. Exposure to 19.2 µg/L of chlordecone increased the abundance of ovipostatin, a peptide transmitted during mating through seminal fluid, which reduces oviposition in this species. The expression of yolk ferritin, the vitellogenin equivalent in L. stagnalis, was reduced after exposure to 94.2 ng Sn/L of tributyltin. The identification of yolk ferritin and the modification of its expression in snails exposed to chemicals were refined using western blot analysis. Our results showed that the tested compounds influenced the abundance of yolk ferritin in the reproductive organs. Alteration in proteins involved in reproductive pathways (e.g., ovipostatin and yolk ferritin) could constitute relevant

    Organisms generally select high-quality diets to obtain maximal energy while devoting the least amount of time and energy. Diets, however, can vary in natural systems. In ecotoxicological testing, the effect of diet type on organismal responses to toxicants has not been explored despite the potential for dietary effects to influence toxicological endpoints. We first evaluated diet quality using growth rate and sensitivity to the fungicide pyraclostrobin of Lymnaea stagnalis fed lettuce (common laboratory diet), turtle pellets (high nutrient composition), and a combination diet of both food items. We also measured the macronutrient content of snails raised on the multiple diets to determine how diet may have impacted energy allocation patterns. Finally, we evaluated whether snails discernibly preferred a particular diet. Snails fed high-nutrient and combination diets grew larger overall than snails fed a lettuce-only diet. Snails fed the high-nutrient and combination diets, both juvenile and adult, were significantly more tolerant to pyraclostrobin than snails fed lettuce. When measured for macronutrient content, snails raised on high-nutrient and combination diets had significantly higher carbohydrate content than snails fed lettuce. Despite the strong effects of diet type, snails did not exhibit a clear diet choice in preference trials. Dietary composition clearly influences growth rate, sensitivity, and macronutrient content of Lymnaea stagnalis. These results suggest that the nutritional environment has potentially strong impacts on toxicant sensitivity. Environ Toxicol Chem 2018;37:1158-1167. © 2017 SETAC. © 2017 SETAC.

    The use of standardized monospecific testing to assess the ecological risk of chemicals implicitly relies on the strong assumption that intraspecific variation in sensitivity is negligible or irrelevant in this context. In this study, we investigated genetic variation in copper sensitivity of the freshwater snail Lymnaea stagnalis, using lineages stemming from eight natural populations or strains found to be genetically differentiated at neutral markers. Copper-induced mortality varied widely among populations, as did the estimated daily death rate and time to 50% mortality (LT50). Population genetic divergence in copper sensitivity was compared to neutral differentiation using the Q ST -F ST approach. No evidence for homogenizing selection could be detected. This result demonstrates that species-level extrapolations from single population studies are highly unreliable. The study provides a simple example of how evolutionary principles could be incorporated into ecotoxicity testing in order to refine ecological risk assessment. - Highlights: • Genetic variation in copper tolerance occurs between Lymnaea stagnalis populations. • We used the Q ST -F ST approach to test evolutionary patterns in copper tolerance. • No evidence for uniform selection was found. • Results suggest that extrapolations to the species level are not safe. • A method is proposed to refine ecological risk assessment using genetic parameters. - Genetic variation in copper tolerance occurs in Lymnaea stagnalis.

    According to our previous results the gastropod Lymnaea stagnalis exposed to MC-producing cyanobacteria accumulates microcystins (MCs) both as free and covalently bound forms in its tissues, therefore representing a potential risk of MC transfer through the food web. This study demonstrates in a laboratory experiment the transfer of free and bound MCs from L. stagnalis intoxicated by MC-producing Planktothrix agardhii ingestion to the fish Gasterosteus aculeatus. Fish were fed during five days with digestive glands of L. stagnalis containing various concentrations of free and bound MCs, then with toxin-free digestive glands during a 5-day depuration period. MC accumulation was measured in gastropod digestive gland and in various fish organs (liver, muscle, kidney, and gills). The impact on fish was evaluated through detoxification enzyme (glutathion-S-transferase, glutathion peroxydase and superoxyde dismutase) activities, hepatic histopathology, and modifications in gill ventilation, feeding and locomotion. G. aculeatus ingestion rate was similar with intoxicated and toxin-free diet. Fish accumulated MCs (up to 3.96±0.14μgg -1 DW) in all organs and in decreasing order in liver, muscle, kidney and gills. Hepatic histopathology was moderate. Glutathion peroxydase was activated in gills during intoxication suggesting a slight reactive oxygen species production, but without any impact on gill ventilation. Intoxication via ingestion of MC-intoxicated snails impacted fish locomotion. Intoxicated fish remained significantly less mobile than controls during the intoxication period possibly due to a lower health condition, whereas they showed a greater mobility during the depuration period that might be related to an acute foraging for food. During depuration, MC elimination was total in gills and kidney, but partial in liver and muscle. Our results assess the MC transfer from gastropods to fish and the potential risk induced by bound MCs in the food web. Copyright

    Full Text Available The paper deals with the peculiarities of distribution of β-carotene and xanthophylls in the body of Lymnaea stagnalis (Linnaeus, 1758 (Pulmonata, Lymnaeidae in the normal conditions and under the action of different concentrations of NH4Cl, depending on duration of exposure (2, 7, 14 and 21 days. L. stagnalis (300 copies were collected in September 2013–2014 (in Zhytomyr region. Toxicant NH4Cl was used in concentrations corresponding to 0.5, 2, 5 and 10 MAC. The content of β-carotene and xanthophylls was determined by the Taylor method. 2400 biochemical analyses were carried out. The article shows that under the action of 0.5 MPC NH4Cl adaptive processes are stimulated in the body of L. stagnalis and total antioxidant activity is activated, as evidenced by changes in the content of β-carotene and xanthophylls in the organs (hepatopancreas, pallium and foot and tissues (hemolymph of the mollusks under study. The research proves that the action of concentration discussed above during 2, 14 and 21 days causes the increase in the content of β-carotene in hepatopancreas (1.63–5.73 times, pallium (1.68–5.37 times and foot (1.81–3.89 times of animals. Incubation of mollusks in solutions of NH4Cl (0.5 MAC for 7 days resulted in the decrease of figures in these organs by 23,6–38,8% relatively to control. It should be noted that from the overall dynamics hemolymph is somewhat distracting; for it 1.35–1.46 times’ decrease in the content of β-carotene after short-term action of the toxicant (2 and 7 days and β-carotene increase by 2.79–7.38 times under conditions of prolonged exposure (14 and 21 days is recorded. The content of xanthophylls correlates with the content of β-carotene on the 2nd, 7th and 14th day of toxic action, but by increasing the time of contact with toxic substances to 21 days the decrease in figures by 20,9–40,7% in foot and pallium is recorded.

    Silver nanoparticles (AgNPs) are widely used in many applications and likely released into the aquatic environment. There is increasing evidence that Ag is efficiently delivered to aquatic organisms from AgNPs after aqueous and dietary exposures. Accumulation of AgNPs through the diet can damage digestion and adversely affect growth. It is well recognized that aspects of water quality, such as hardness, affect the bioavailability and toxicity of waterborne Ag. However, the influence of water chemistry on the bioavailability and toxicity of dietborne AgNPs to aquatic invertebrates is largely unknown. Here we characterize for the first time the effects of water hardness and humic acids on the bioaccumulation and toxicity of AgNPs coated with polyvinyl pyrrolidone (PVP) to the freshwater snail Lymnaea stagnalis after dietary exposures. Our results indicate that bioaccumulation and toxicity of Ag from PVP-AgNPs ingested with food are not affected by water hardness and by humic acids, although both could affect interactions with the biological membrane and trigger nanoparticle transformations. Snails efficiently assimilated Ag from the PVP-AgNPs mixed with diatoms (Ag assimilation efficiencies ranged from 82 to 93%). Rate constants of Ag uptake from food were similar across the entire range of water hardness and humic acid concentrations. These results suggest that correcting regulations for water quality could be irrelevant and ineffective where dietary exposure is important. - Highlights: • AgNP coated with polyvinyl pyrrolidone (PVP), PVP-AgNP were efficiently assimilated by Lymnaea stagnalis. • Water chemistry has no influence on the dietary uptake of PVP-AgNP by snails. - L. Stagnalis assimilated PVP-AgNPs efficiently from food and water chemistry had no influence on their uptake and toxicity

    The hermaphroditic gastropod Lymnaea stagnalis is proposed as a candidate species for the development of OECD guidelines for testing of the reprotoxicity of chemicals, including endocrine active substances (EASs). Up to now, only a few putative EASs have been tested for their reproductive toxicity in this species. In this study, we investigate the effects of four EASs with different affinities to the vertebrate estrogen and androgen receptors (chlordecone as an estrogen; cyproterone acetate, fenitrothion and vinclozolin as anti-androgens) on the reproduction of L. stagnalis in a 21-day semi-static test. Testosterone and 17α-ethinylestradiol (EE2) were used as the reference compounds. The tested EASs had no significant effect on growth and survival at the tested concentration ranges (ng to μg/L). Classical reproduction endpoints (i.e., oviposition and fecundity) were not responsive to the tested chemicals, except for chlordecone and 17α-ethinylestradiol, which hampered reproduction from 19.6 μg/L and 17.6 μg/L, respectively. The frequency of polyembryonic eggs, used as an additional endpoint, demonstrated the effects of all compounds except EE2. The molecular pathways, which are involved in such reproduction impairments, remain unknown. Our results suggest that egg quality is a more sensitive endpoint as compared to other reproductive endpoints commonly assessed in mollusk toxicity tests. Copyright © 2014 Elsevier B.V.

    Hepatotoxins are frequently produced by many cyanobacterial species. Microcystins (MCs) are the most frequent and widely studied hepatotoxins, with potentially hazardous repercussions on aquatic organisms. As a ubiquitous herbivore living in eutrophic freshwaters, the snail Lymnaea stagnalis (Gastropoda: Pulmonata) is particularly exposed to cyanobacteria. The toxic filamentous Planktothrix agardhii is common in temperate lakes and is therefore, a potential food resource for gastropods. In the first part of this study, we demonstrated the ingestion of toxic P. agardhii by L. stagnalis during a 5 weeks exposure, with concomitant accumulation of, on average, 60% of total MCs ingested. After 3 weeks of non-toxic food (lettuce), approximately 90% of MCs were eliminated from tissues. Here, we investigate the impact of toxic P. agardhii consumption on the life-history traits (survival, growth and fecundity), locomotion and the structure of digestive and genital glands of juvenile and adult L. stagnalis. We observed a decrease of growth regardless of age, although this was more marked in juveniles, and a reduction of fecundity in adults. Survival and locomotion were not affected. Reduction of growth and fecundity continued to be observed even after feeding of non-toxic food for 3 weeks. The structure of the digestive gland was altered during the intoxication period but not irreversibly as cells tended to recover a normal status after the 3-week detoxification period. No histopathological changes occurred in the genital gland and oocytes, and spermatozoids were present in the gonadic acini. The density of cyanobacterial suspensions used in this study was comparable to those regularly observed in lakes, particularly in eutrophic waters. These results are discussed in terms of the negative impact of toxic cyanobacteria on natural communities of freshwater gastropods, and potential cascading effects on the equilibrium and functioning of the ecosystem.

    Tributyltin (TBT) and triphenyltin (TPT) are emblematic endocrine disruptors, which have been mostly studied in gonochoric prosobranchs. Although both compounds can simultaneously occur in the environment, they have mainly been tested separately for their effects on snail reproduction. Because large discrepancies in experimental conditions occurred in these tests, the present study aimed to compare the relative toxicity of TBT and TPT under similar laboratory conditions in the range of 0 ng Sn/L to 600 ng Sn/L. Tests were performed on the simultaneous hermaphrodite Lymnaea stagnalis, a freshwater snail in which effects of TPT were unknown. Survival, shell length, and reproduction were monitored in a 21-d semistatic test. Frequency of abnormal eggs was assessed as an additional endpoint. Triphenyltin hampered survival while TBT did not. Major effects on shell solidity and reproduction were observed for both compounds, reproductive outputs being more severely hampered by TBT than by TPT. Considering the frequency of abnormal eggs allowed increasing test sensitivity, because snail responses to TBT could be detected at concentrations as low as 19 ng Sn/L. However, the putative mode of action of the 2 compounds could not be deduced from the structure of the molecules or from the response of apical endpoints. Sensitivity of L. stagnalis to TBT and TPT was compared with the sensitivity of prosobranch mollusks with different habitats and different reproductive strategies. Copyright © 2013 SETAC.

    Long-term effects of endocrine disruptors (EDs) on aquatic invertebrates remain difficult to assess, mainly due to the lack of appropriate sensitive toxicity test methods and relevant data analysis procedures. This study aimed at identifying windows of sensitivity to EDs along the life-cycle of the freshwater snail Lymnaea stagnalis, a candidate species for the development of forthcoming test guidelines. Juveniles, sub-adults, young adults and adults were exposed for 21 days to the fungicide vinclozolin (VZ). Survival, growth, onset of reproduction, fertility and fecundity were monitored weekly. Data were analyzed using standard statistical analysis procedures and mixed-effect models. No deleterious effect on survival and growth occurred in snails exposed to VZ at environmentally relevant concentrations. A significant impairment of the male function occurred in young adults, leading to infertility at concentrations exceeding 0.025 μg/L. Furthermore, fecundity was impaired in adults exposed to concentrations exceeding 25 μg/L. Biological responses depended on VZ concentration, exposure duration and on their interaction, leading to complex response patterns. The use of a standard statistical approach to analyze those data led to underestimation of VZ effects on reproduction, whereas effects could reliably be analyzed by mixed-effect models. L. stagnalis may be among the most sensitive invertebrate species to VZ, a 21-day reproduction test allowing the detection of deleterious effects at environmentally relevant concentrations of the fungicide. These results thus reinforce the relevance of L. stagnalis as a good candidate species for the development of guidelines devoted to the risk assessment of EDs.

    The msx gene family is one of the most highly conserved of the nonclustered homeobox-containing genes. We have isolated an msx homolog (Le-msx) from the glossiphoniid leech, Helobdella robusta, and characterized its pattern of expression by whole mount in situ hybridization. In situ expression and reverse transcription polymerase chain reaction (RT-PCR) data results show that Le-msx is a maternal transcript initially uniformly distributed in the cortex of immature oocytes that becomes asymmetrically localized to the polar regions of the uncleaved zygote. This is the earliest reported expression for the msx gene family and the first maternally expressed homeodomain-containing transcription factor reported in annelids. During embryonic development, Le-msx is expressed in all 10 embryonic stem cells and their segmental founder cell descendants. At midembryonic stages, Le-msx is expressed in the expanding germinal plate. Le-msx is confined to the central nervous system and nephridia at late (stage 9) stages and subsequently disappears from nephridia. In addition, we present a phylogenetic hypothesis for the evolution of the msx gene family, including the identification of a putative C. elegans msx homolog and the realignment of the sponge msx homolog to the NK class of homeodomain genes.

In the previous studies carried out in Central Europe, a very similar spectrum of nine trematode families of 22 cercariae determined to species level and 43 types of cercariae reported under generic or provisional names, which can be in many cases conspecific with the previous taxa, were found. A simple key to identification of cercariae and metacercariae, together with their illustrations, is provided.

    Bimiracidial infections of Lymnaea palustris and Lymnaea stagnalis (shell height at exposure, 4 mm) with Fasciola hepatica were carried out during six successive snail generations to determine if prevalence and intensity of snail infection increased over time through descendants issuing from eggs laid by parents already exposed to this digenean. Controls were constituted by a French population of Galba truncatula (a single generation) infected according to the same protocol. In a first experiment performed with the F1 to F5 generations of L. palustris, the prevalence and intensity of F. hepatica infection in snails progressively increased. Immature rediae and a few cercariae-containing rediae of the digenean were observed in L. stagnalis from the F3 generation, but no free cercaria was noted in the bodies of this lymnaeid from the F4 to F6 generations. In another experiment carried out with the F6 generation of L. palustris, the prevalence of F. hepatica infection and the number of shed cercariae were significantly lower in L. palustris than in G. truncatula. This mode of snail infection suggests an explanation for cases of human fasciolosis occurring in central France after the collection of wild watercress from beds where L. palustris was the sole lymnaeid.

    In Lymnaea stagnalis, in order to obtain a 10 min short-term memory (STM) of taste avoidance conditioning (TAC) at least 10 paired presentations of a conditioned stimulus (CS), sucrose, and an unconditioned stimulus (US), tactile stimulation to the animal's head, are required. Pre-exposure of snails to the protein kinase C (PKC) α and ε activator bryostatin (Bryo) facilitated STM formation in that only 5 paired CS-US trials were required. Typically 20 paired presentations of the CS-US are required for formation of STM and LTM. However, 20 paired presentations do not result in STM or LTM if snails are pre-incubated with a PKC inhibitor, Ro-32-0432. We also found that LTM lasting longer than 48 h was acquired with Bryo incubation for 45 min even after termination of the conditioning paradigm. These data suggest that activation of the α and ε isozymes of PKC is crucially involved in the formation of LTM and provide further support for a mechanism that has been conserved across the evolution of species ranging from invertebrate molluscs to higher mammals.

    An attempt was made to characterise the bioavailability of 237 Pu and 241 Am for the pond snail Lymnaea stagnalis L. in selected surface waters. The uptake, distribution and retention patterns were studied through the contamination route water-snail. The effects of a number of parameters, such as seasonal variation, water type (pH, conductivity, ionic composition) and presence of food, on the bioavailability of the transuranics were evaluated. Finally, an assessment was made concerning the chemical speciation of plutonium and americium in the selected freshwaters

    Neonicotinoid insecticides, which act on nicotinic acetylcholine receptors (nAChRs) in a variety of ways, have extremely low mammalian toxicity, yet the molecular basis of such actions is poorly understood. To elucidate the molecular basis for nAChR-neonicotinoid interactions, a surrogate protein, acetylcholine binding protein from Lymnaea stagnalis (Ls-AChBP) was crystallized in complex with neonicotinoid insecticides imidacloprid (IMI) or clothianidin (CTD). The crystal structures suggested that the guanidine moiety of IMI and CTD stacks with Tyr185, while the nitro group of IMI but not of CTD makes a hydrogen bond with Gln55. IMI showed higher binding affinity for Ls-AChBP than that of CTD, consistent with weaker CH-pi interactions in the Ls-AChBP-CTD complex than in the Ls-AChBP-IMI complex and the lack of the nitro group-Gln55 hydrogen bond in CTD. Yet, the NH at position 1 of CTD makes a hydrogen bond with the backbone carbonyl of Trp143, offering an explanation for the diverse actions of neonicotinoids on nAChRs.

    The great pond snail, Lymnaea stagnalis, is commonly used as a model species to study how stress affects the ability to form long-term memory (LTM); however, we still have little information about how the snail senses stressful stimuli. The osphradium is an external sensory organ that demonstrates electrophysiological responses to a variety of external chemical stimuli. We examined the role, if any, played by the osphradium in sensing two environmental stressors, crowding and low environmental calcium, both known to block LTM in intact animals. We severed the osphradial nerve, blocking external sensory input from this organ to the central nervous system, and then exposed the snails to low environmental calcium or crowding stress to assess whether these stressors continued to block LTM formation. When exposed to low environmental calcium, snails with their osphradial nerve severed responded as if they were maintained in our standard calcium environment. That is, they did not respond to low calcium as a stressor blocking LTM; therefore, the osphradium plays a crucial role in mediating how snails respond to this stressor. However, following crowding, LTM formation was blocked in both control groups and snails that had the osphradial nerve severed, indicating that sensory information from the osphradium is not required to sense crowded conditions. Together these data show that two stressors that result in the same behavioural phenotype, blocking LTM formation, do so via two distinct sensory pathways.

    Freshwater gastropods are increasingly exposed to multiple stressors in the field such as the herbicide glyphosate in Roundup formulations and cyanobacterial blooms either producing or not producing microcystins (MCs), potentially leading to interacting effects. Here, the responses of Lymnaea stagnalis to a 21-day exposure to non-MC or MC-producing (33μgL(-1)) Planktothrix agardhii alone or in combination with the commercial formulation RoundUp(®) Flash at a concentration of 1μgL(-1) glyphosate, followed by 14days of depuration, were studied via i) accumulation of free and bound MCs in tissues, and ii) activities of anti-oxidant (catalase CAT) and biotransformation (glutathione-S-transferase GST) enzymes. During the intoxication, the cyanobacterial exposure induced an early increase of CAT activity, independently of the MC content, probably related to the production of secondary cyanobacterial metabolites. The GST activity was induced by RoundUp(®) Flash alone or in combination with non MC-producing cyanobacteria, but was inhibited by MC-producing cyanobacteria with or without RoundUp(®) Flash. Moreover, MC accumulation in L. stagnalis was 3.2 times increased when snails were concomitantly exposed to MC-producing cyanobacteria with RoundUp(®), suggesting interacting effects of MCs on biotransformation processes. The potent inhibition of detoxication systems by MCs and RoundUp(®) Flash was reversible during the depuration, during which CAT and GST activities were significantly higher in snails previously exposed to MC-producing cyanobacteria with or without RoundUp(®) Flash than in other conditions, probably related to the oxidative stress caused by accumulated MCs remaining in tissues.

  17. Silver nanoparticles alter learning and memory formation in an aquatic organism, Lymnaea stagnalis.

    We tested the effect of silver nanoparticles (AgNPs) on the ability of the pond snail, Lymnaea stagnalis, to learn and form long-term memory (LTM) following operant conditioning of aerial respiration. We hypothesized that the AgNPs would act as a stressor and prevent learning and LTM formation. We tested snails exposed for either 72 h or only during training and testing for memory (i.e. 0.5 h) and found no difference between those treatments. We found that at a low concentration of AgNPs (5 μg/L) neither learning and nor memory formation were altered. When we increased the concentration of AgNPs (10 μg/L) we found that memory formation was enhanced. Finally, at a higher concentration (50 μg/L) memory formation was blocked. To determine if the disassociation of Ag + from the AgNPs caused the effects on memory we performed similar experiments with AgNO 3 and found similar concentration-dependent results. Finally, we found that snails perceive the AgNPs differently from Ag+ as there was context specific memory. That is, snails trained in AgNPs did not show memory when tested in Ag + and vice-versa. We believe that changes in memory formation may be a more sensitive determination of AgNPs on aquatic organisms than the determination of a LC 50 . Crown Copyright © 2017. Published by Elsevier Ltd.

    The use of standardized monospecific testing to assess the ecological risk of chemicals implicitly relies on the strong assumption that intraspecific variation in sensitivity is negligible or irrelevant in this context. In this study, we investigated genetic variation in copper sensitivity of the freshwater snail Lymnaea stagnalis, using lineages stemming from eight natural populations or strains found to be genetically differentiated at neutral markers. Copper-induced mortality varied widely among populations, as did the estimated daily death rate and time to 50% mortality (LT50). Population genetic divergence in copper sensitivity was compared to neutral differentiation using the QST-FST approach. No evidence for homogenizing selection could be detected. This result demonstrates that species-level extrapolations from single population studies are highly unreliable. The study provides a simple example of how evolutionary principles could be incorporated into ecotoxicity testing in order to refine ecological risk assessment. Copyright © 2015 Elsevier Ltd.

    During the period of this report, we have made a number of important discoveries. To date this work has led to 4 peer-reviewed publications in primary research journals plus 1 minireview and 1 chapter in the proceedings of a meeting. Publications resulting from this grant support are enumerated at the end of the report. Two additional, on-going studies also described. 1. Using laser cell ablation, we have obtained evidence that an annelid - the leech Helobdella robusta - patterns the anteroposterior (AP) polarity of its nascent segment primordia independent of cell interactions oriented along the AP axis. 2. We cloned a Helobdella homologue (hro-hh) of the Drosophila segment polarity gene hedgehog, and used in situ hybridization and northern blots to characterize its expression in the embryo. 3. We have used laser cell ablations to examine the possible role of cell interactions during the developmental patterning of the 4 rostralmost "head" segments of the leech Helobdella robusta.

    Modern toxicology is seeking new testing methods to better understand toxicological effects. One of the most concerning chemicals is the neonicotinoid pesticide imidacloprid. Although imidacloprid is designed to target insects, recent studies have shown adverse effects on nontarget species. Metabolomics was applied to investigate imidacloprid-induced sublethal toxicity in the central nervous system of the freshwater snail Lymnaea stagnalis. The snails (n = 10 snails) were exposed for 10 days to increasing imidacloprid concentrations (0.1, 1, 10, and 100 μg/L). The comparison between control and exposure groups highlighted the involvement and perturbation of many biological pathways. The levels of several metabolites belonging to different metabolite classes were significantly changed by imidacloprid exposure. A change in the amino acids and nucleotide metabolites like tryptophan, proline, phenylalanine, uridine, and guanosine was found. Many fatty acids were down-regulated, and the levels of the polyamines, spermidine and putrescine, were found to be increased which is an indication of neuron cell injury. A turnover increase between choline and acetylcholine led us to hypothesize an increase in cholinergic gene expression to overcome imidacloprid binding to the nicotinic acetylcholine receptors. Metabolomics revealed imidacloprid induced metabolic changes at low and environmentally relevant concentration in a nontarget species and generated a novel mechanistic hypothesis.

    Pesticide use leads to complex exposure and response patterns in non-target aquatic species, so that the analysis of data from standard toxicity tests may result in unrealistic risk forecasts. Developing models that are able to capture such complexity from toxicity test data is thus a crucial issue for pesticide risk assessment. In this study, freshwater snails from two genetically differentiated populations of Lymnaea stagnalis were exposed to repeated acute applications of environmentally realistic concentrations of the herbicide diquat, from the embryo to the adult stage. Hatching rate, embryonic development duration, juvenile mortality, feeding rate and age at first spawning were investigated during both exposure and recovery periods. Effects of diquat on mortality were analysed using a threshold hazard model accounting for time-varying herbicide concentrations. All endpoints were significantly impaired at diquat environmental concentrations in both populations. Snail evolutionary history had no significant impact on their sensitivity and responsiveness to diquat, whereas food acted as a modulating factor of toxicant-induced mortality. The time course of effects was adequately described by the model, which thus appears suitable to analyse long-term effects of complex exposure patterns based upon full life cycle experiment data. Obtained model outputs (e.g. no-effect concentrations) could be directly used for chemical risk assessment.

Species recruitment occurred mostly at September, December and March when juveniles were very abundant. Although several species of Helobdella were able to live in the disturbed section of the stream, only H. simplex and H. hyalina sustained large populations at the site and can be considered as tolerant to organic enrichment. This information is valuable to future studies on stream condition assessment in mountainous areas in Patagonia, and in other areas in which these species are present.

    The presence of pesticides in the environment results in potential unwanted effects on non-target species. Freshwater organisms inhabiting water bodies adjacent to agricultural areas, such as ditches, ponds and marshes, are good models to test such effects as various pesticides may reach these habitats through several ways, including aerial drift, run-off, and drainage. Diquat is a non-selective herbicide used for crop protection or for weed control in such water bodies. In this study, we investigated the effects of diquat on a widely spread aquatic invertebrate, the holarctic freshwater snail Lymnaea stagnalis. Due to the known redox-cycling properties of diquat, we studied transcript expression and enzymatic activities relative to oxidative and general stress in the haemolymph and gonado-digestive complex (GDC). As diquat is not persistent, snails were exposed for short times (5, 24, and 48 h) to ecologically relevant concentrations (22.2, 44.4, and 222.2 {mu}g l{sup -1}) of diquat dibromide. RT-qPCR was used to quantify the transcription of genes encoding catalase (cat), a cytosolic superoxide dismutase (Cu/Zn-sod), a selenium-dependent glutathione peroxidase (gpx), a glutathione reductase (gred), the retinoid X receptor (rxr), two heat shock proteins (hsp40 and hsp70), cortactin (cor) and the two ribosomal genes r18S and r28s. Enzymatic activities of SOD, Gpx, Gred and glutathione S-transferase (GST) were investigated in the GDC using spectrophoto/fluorometric methods. Opposite trends were obtained in the haemolymph depending on the herbicide concentration. At the lowest concentration, effects were mainly observed after 24 h of exposure, with over-transcription of cor, hsp40, rxr, and sod, whereas higher concentrations down-regulated the expression of most of the studied transcripts, especially after 48 h of exposure. In the GDC, earlier responses were observed and the fold-change magnitude was generally much higher: transcription of all target genes increased

  4. On the Ultrastructure and Function of Rhogocytes from the Pond Snail Lymnaea stagnalis.

    Full Text Available Rhogocytes, also termed "pore cells", occur as solitary or clustered cells in the connective tissue of gastropod molluscs. Rhogocytes possess an enveloping lamina of extracellular matrix and enigmatic extracellular lacunae bridged by cytoplasmic bars that form 20 nm diaphragmatic slits likely to act as a molecular sieve. Recent papers highlight the embryogenesis and ultrastructure of these cells, and their role in heavy metal detoxification. Rhogocytes are the site of hemocyanin or hemoglobin biosynthesis in gastropods. Based on electron microscopy, we recently proposed a possible pathway of hemoglobin exocytosis through the slit apparatus, and provided molecular evidence of a common phylogenetic origin of molluscan rhogocytes, insect nephrocytes and vertebrate podocytes. However, the previously proposed secretion mode of the respiratory proteins into the hemolymph is still rather hypothetical, and the possible role of rhogocytes in detoxification requires additional data. Although our previous study on rhogocytes of the red-blooded (hemoglobin-containing freshwater snail Biomphalaria glabrata provided much new information, a disadvantage was that the hemoglobin molecules were not unequivocally defined in the electron microscope. This made it difficult to trace the exocytosis pathway of this protein. Therefore, we have now performed a similar study on the rhogocytes of the blue-blooded (hemocyanin-containing freshwater snail Lymnaea stagnalis. The intracellular hemocyanin could be identified in the electron microscope, either as individual molecules or as pseudo-crystalline arrays. Based on 3D-electron microscopy, and supplemented by in situ hybridization, immunocytochemistry and stress response experiments, we provide here additional details on the structure and hemocyanin biosynthesis of rhogocytes, and on their response in animals under cadmium and starvation stress. Moreover, we present an advanced model on the release of synthesized

    Accumulation of free microcystins (MCs) in freshwater gastropods has been demonstrated but accumulation of MCs covalently bound to tissues has never been considered so far. Here, we follow the accumulation of total (free and bound) MCs in Lymnaea stagnalis exposed to i) dissolved MC-LR (33 and 100 microg L(-1)) and ii) Planktothrix agardhii suspensions producing 5 and 33 microg MC-LR equivalents L(-1) over a 5-week period, and after a 3-week depuration period. Snails exposed to dissolved MC-LR accumulated up to 0.26 microg total MCs g(-1) dry weight (DW), with no detection of bound MCs. Snails exposed to MCs producing P. agardhii accumulated up to 69.9 microg total MCs g(-1) DW, of which from 17.7 to 66.7% were bound. After depuration, up to 15.3 microg g(-1) DW of bound MCs were detected in snails previously exposed to toxic cyanobacteria, representing a potential source of MCs transfer through the food web.

    The aim of our study was to distinguish the stress-related molecular response of the pulmonate mollusc Lymnaea stagnalis from the Chernobyl area in comparison with the consequences of other harmful effects, including the short-term effects of radiation and heating. Specimens inhabiting ponds near the Chernobyl nuclear power plant, the cooling channel of the electric power station and the soil reclamation channel (groups R, T and C, correspondingly), and specimens adapted to laboratory conditions (a control group (CL), a disposable group exposed to 2 mGy X-ray radiation over the body (RL), and a group exposed to 25 deg. C for 4 days (TL)) were compared. Despite high variability of responses, Principle Component Analysis distinctly separated the laboratory and feral groups into two sets. In the feral groups, low levels of the stress-related and metal-binding protein metallothionein (MT), protein carbonyls and lactate dehydrogenase in the digestive gland were indicated. The main separating criteria selected by classification and regression tree analysis were the protein carbonyls, cholinesterase and MT. Molluscs from group R were clearly distinguished by the lowest levels of MT, Mn-superoxide dismutase and lactate dehydrogenase, and the highest level of glutathione, demonstrating that the oppression of the gene-determined stress-related response and its partially metabolic compensation can be possible markers for chronic environmental effects of irradiation.

    In the freshwater environment species often rely on chemosensory information to modulate behavior. The pond snail, Lymnaea stagnalis, is a model species used to characterize the causal mechanisms of long-term memory (LTM) formation. Chemical stressors including crayfish kairomones and KCl enhance LTM formation (≥24 h) in Lymnaea; however, how these stressors are sensed and the mechanism by which they affect the electrophysiological properties of neurons necessary for memory formation are poorly understood. Here, we assessed whether the osphradium, a primary chemosensory organ in Lymnaea, modulates LTM enhancement. To test this we severed the osphradial nerve proximal to the osphradium, using sham-operated animals as controls, and assessed the behavioral and electrophysiological response to crayfish kairomones and KCl. We operantly conditioned aerial respiratory behavior in intact, sham and osphradially cut animals, and tested for enhanced memory formation after exposure to the chemical stressors. Sham-operated animals displayed the same memory enhancement as intact animals but snails with a severed osphradial nerve did not show LTM enhancement. Extracellular recordings made from the osphradial nerve demonstrate that these stressors evoked afferent sensory activity. Intracellular recordings from right pedal dorsal 1 (RPeD1), a neuron necessary for LTM formation, demonstrate that its electrophysiological activity is altered by input from the osphradium following exposure to crayfish kairomones or KCl in sham and intact animals but no response is seen in RPeD1 in osphradially cut animals. Therefore, sensory input from the osphradium is necessary for LTM enhancement following exposure to these chemical stressors.

    Silver nanoparticles (AgNPs) are widely used in many applications and likely released into the aquatic environment. There is increasing evidence that Ag is efficiently delivered to aquatic organisms from AgNPs after aqueous and dietary exposures. Accumulation of AgNPs through the diet can damage digestion and adversely affect growth. It is well recognized that aspects of water quality, such as hardness, affect the bioavailability and toxicity of waterborne Ag. However, the influence of water chemistry on the bioavailability and toxicity of dietborne AgNPs to aquatic invertebrates is largely unknown. Here we characterize for the first time the effects of water hardness and humic acids on the bioaccumulation and toxicity of AgNPs coated with polyvinyl pyrrolidone (PVP) to the freshwater snail Lymnaea stagnalis after dietary exposures. Our results indicate that bioaccumulation and toxicity of Ag from PVP-AgNPs ingested with food are not affected by water hardness and by humic acids, although both could affect interactions with the biological membrane and trigger nanoparticle transformations. Snails efficiently assimilated Ag from the PVP-AgNPs mixed with diatoms (Ag assimilation efficiencies ranged from 82 to 93%). Rate constants of Ag uptake from food were similar across the entire range of water hardness and humic acid concentrations. These results suggest that correcting regulations for water quality could be irrelevant and ineffective where dietary exposure is important.

Here, we follow the accumulation of total (free and bound) MCs in Lymnaea stagnalis exposed to i) dissolved MC-LR (33 and 100 μg L -1 ) and ii) Planktothrix agardhii suspensions producing 5 and 33 μg MC-LR equivalents L -1 over a 5-week period, and after a 3-week depuration period. Snails exposed to dissolved MC-LR accumulated up to 0.26 μg total MCs g -1 dry weight (DW), with no detection of bound MCs. Snails exposed to MCs producing P. agardhii accumulated up to 69.9 μg total MCs g -1 DW, of which from 17.7 to 66.7% were bound. After depuration, up to 15.3 μg g -1 DW of bound MCs were detected in snails previously exposed to toxic cyanobacteria, representing a potential source of MCs transfer through the food web. - The study concerns accumulation and elimination of both free and bound microcystins (MCs) in tissues of a gastropod exposed to MCs producing cyanobacteria or dissolved MC-LR.

  11. Coordination of locomotor and cardiorespiratory networks of Lymnaea stagnalis by a pair of identified interneurones.

    1. The morphology and electrophysiology of a newly identified bilateral pair of interneurones in the central nervous system of the pulmonate pond snail Lymnaea stagnalis is described. 2. These interneurones, identified as left and right pedal dorsal 11 (L/RPeD11), are electrically coupled to each other as well as to a large number of foot and body wall motoneurones, forming a fast-acting neural network which coordinates the activities of foot and body wall muscles. 3. The left and right sides of the body wall of Lymnaea are innervated by left and right cerebral A cluster neurones. Although these motoneurones have only ipsilateral projections, they are indirectly electrically coupled to their contralateral homologues via their connections with L/RPeD11. Similarly, the activities of left and right pedal G cluster neurones, which are known to be involved in locomotion, are also coordinated by L/RPeD11. 4. Selective ablation of both neurones PeD11 results in the loss of coordination between the bilateral cerebral A clusters. 5. Interneurones L/RPeD11 are multifunctional. In addition to coordinating motoneuronal activity, they make chemical excitatory connections with heart motoneurones. They also synapse upon respiratory motoneurones, hyperpolarizing those involved in pneumostome opening (expiration) and depolarizing those involved in pneumostome closure (inspiration). 6. An identified respiratory interneurone involved in pneumostome closure (visceral dorsal 4) inhibits L/RPeD11 together with all their electrically coupled follower cells. 7. Both L/RPeD11 have strong excitatory effects on another pair of electrically coupled neurones, visceral dorsal 1 and right parietal dorsal 2, which have previously been shown to be sensitive to changes in the partial pressure of environmental oxygen (PO2). 8. Although L/RPeD11 participate in whole-body withdrawal responses, electrical stimulation applied directly to these neurones was not sufficient to induce this behaviour.

  12. Crystal structure of Lymnaea stagnalis AChBP complexed with the potent nAChR antagonist DHβE suggests a unique mode of antagonism.

    Directory of Open Access Journals (Sweden)

    Full Text Available Nicotinic acetylcholine receptors (nAChRs are pentameric ligand-gated ion channels that belong to the Cys-loop receptor superfamily. These receptors are allosteric proteins that exist in different conformational states, including resting (closed, activated (open, and desensitized (closed states. The acetylcholine binding protein (AChBP is a structural homologue of the extracellular ligand-binding domain of nAChRs. In previous studies, the degree of the C-loop radial extension of AChBP has been assigned to different conformational states of nAChRs. It has been suggested that a closed C-loop is preferred for the active conformation of nAChRs in complex with agonists whereas an open C-loop reflects an antagonist-bound (closed state. In this work, we have determined the crystal structure of AChBP from the water snail Lymnaea stagnalis (Ls in complex with dihydro-β-erythroidine (DHβE, which is a potent competitive antagonist of nAChRs. The structure reveals that binding of DHβE to AChBP imposes closure of the C-loop as agonists, but also a shift perpendicular to previously observed C-loop movements. These observations suggest that DHβE may antagonize the receptor via a different mechanism compared to prototypical antagonists and toxins.

    Nickel bioavailability is reduced in the presence of dissolved organic carbon (DOC), suspended solids (TSS), and other complexing ligands; however, no studies have examined the relative importance of Ni exposure through different compartments (water, sediment, food). Hyalella azteca and Lymnaea stagnalis were exposed to Ni-amended water, sediment, and food, either separately or in combination. Both organisms experienced survival and growth effects in several Ni compartment tests. The DOC amendments attenuated L. stagnalis Ni effects (survival, growth, and (62)Ni bioaccumulation), and presence of TSS exposures demonstrated both protective and synergistic effects on H. azteca and L. stagnalis. (62)Ni trophic transfer from food to H. azteca and L. stagnalis was negligible; however, bioaccumulating (62)Ni was attributed to (62)Ni-water ((62)Ni flux from food), (62)Ni-TSS, and (62)Ni-food. Overall, H. azteca and L. stagnalis Ni compartment toxicity increased in the following order: Ni-water > Ni-sediment > Ni-all (water, sediment, food) > Ni-food. Copyright © 2015 Elsevier Ltd.

    Toxicokinetic-toxicodynamic (TKTD) modeling offers many advantages in the analysis of ecotoxicity test data. Calibration of TKTD models, however, places different demands on test design compared with classical concentration-response approaches. In the present study, useful complementary information is provided regarding test design for TKTD modeling. A case study is presented for the pond snail Lymnaea stagnalis exposed to the narcotic compound acetone, in which the data on all endpoints were analyzed together using a relatively simple TKTD model called DEBkiss. Furthermore, the influence of the data used for calibration on accuracy and precision of model parameters is discussed. The DEBkiss model described toxic effects on survival, growth, and reproduction over time well, within a single integrated analysis. Regarding the parameter estimates (e.g., no-effect concentration), precision rather than accuracy was affected depending on which data set was used for model calibration. In addition, the present study shows that the intrinsic sensitivity of snails to acetone stays the same across different life stages, including the embryonic stage. In fact, the data on egg development allowed for selection of a unique metabolic mode of action for the toxicant. Practical and theoretical considerations for test design to accommodate TKTD modeling are discussed in the hope that this information will aid other researchers to make the best possible use of their test animals. © 2014 SETAC.

    Gaining insight into how natural trait variation is manifest in populations shaped by differential environmental factors is crucial to understanding the evolution, ecology and sensory biology of natural populations. We have demonstrated that lab-reared Lymnaea detect and respond to the scent of a crayfish predator with specific, appropriate anti-predator behavioral responses, including enhanced long-term memory (LTM) formation, and that such predator detection significantly alters the electrophysiological activity of RPeD1, a neuron that is a necessary site for LTM formation. Here we ask: (1) do distinct populations of wild Lymnaea stagnalis respond only to sympatric predators and if so, can these traits be quantified at both the behavioral and neurophysiological levels, and (2) does the presence of a non-sympatric predator elicit anti-predator behaviors including augmentation of LTM? We tested three different populations of wild (i.e. not lab-reared) snails freshly collected from their natural habitat: (1) polders near Utrecht in The Netherlands, (2) six seasonally isolated ponds in the Belly River drainage in southern Alberta, Canada and (3) a 20-year-old human-made dugout pond in southern Alberta. We found strain-specific variations in the ability to form LTM and that only a sympatric predator evoked anti-predatory behaviors, including enhanced LTM formation and changes in RPeD1 activity.

    The pond snail Lymnaea stagnalis is capable of learning taste aversion and consolidating this learning into long-term memory (LTM) that is called conditioned taste aversion (CTA). Previous studies showed that some molluscan insulin-related peptides (MIPs) were upregulated in snails exhibiting CTA. We thus hypothesized that MIPs play an important role in neurons underlying the CTA-LTM consolidation process. To examine this hypothesis, we first observed the distribution of MIP II, a major peptide of MIPs, and MIP receptor and determined the amounts of their mRNAs in the CNS. MIP II was only observed in the light green cells in the cerebral ganglia, but the MIP receptor was distributed throughout the entire CNS, including the buccal ganglia. Next, when we applied exogenous mammalian insulin, secretions from MIP-containing cells or partially purified MIPs, to the isolated CNS, we observed a long-term change in synaptic efficacy (i.e., enhancement) of the synaptic connection between the cerebral giant cell (a key interneuron for CTA) and the B1 motor neuron (a buccal motor neuron). This synaptic enhancement was blocked by application of an insulin receptor antibody to the isolated CNS. Finally, injection of the insulin receptor antibody into the snail before CTA training, while not blocking the acquisition of taste aversion learning, blocked the memory consolidation process; thus, LTM was not observed. These data suggest that MIPs trigger changes in synaptic connectivity that may be correlated with the consolidation of taste aversion learning into CTA-LTM in the Lymnaea CNS.

    During the first four mitotic division cycles of Lymnaea stagnalis embryos, we have detected cell cycle-dependent changes in the pattern of transcellular ionic currents and membrane-bound Ca 2+ -stimulated ATPase activity. Ionic currents ranging from 0.05 to 2.50 μA/cm 2 have been measured using the vibrating probe technique. Enzyme activity was detected using Ando's cytochemical method (Ando et al. 1981) which reveals Ca 2+ /Mg 2+ ATPase localization at the ultrastructural level, and under high-stringency conditions with respect to calcium availability, it reveals Ca 2+ -stimulated ATPase. The ionic currents and Ca 2+ -stimulated ATPase localization have in common that important changes occur during the M-phase of the cell cycles. Minimal outward current at the vegetal pole coincides with metaphase/anaphase. Maximal inward current at the animal pole coincides with the onset of cytokinesis at that pole. Ca 2+ -stimulated ATPase is absent from one half of the embryo at metaphase/anaphase of the two- and four-cell stage, whereas it is present in all cells during the remaining part of the cell cycle. Since fluctuations of cytosolic free calcium concentrations appear to correlate with both karyokinesis and cytokinesis, we speculate that part of the cyclic pattern of Ca 2+ -stimulated ATPase localization and of the transcellular ionic currents reflects the elevation of cytosolic free calcium concentration during the M-phase.

    With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic capacity of the aging nervous system for plasticity (1). Here, using a molluscan model system, we show that the age-related decline in memory performance can be reversed by administration of the pituitary adenylate cyclase activating polypeptide (PACAP). Our earlier findings showed that a homolog of the vertebrate PACAP38 and its receptors exist in the pond snail (Lymnaea stagnalis) brain (2), and it is both necessary and instructive for memory formation after reward conditioning in young animals (3). Here we show that exogenous PACAP38 boosts memory formation in aged Lymnaea, where endogenous PACAP38 levels are low in the brain. Treatment with insulin-like growth factor-1, which in vertebrates was shown to transactivate PACAP type I (PAC1) receptors (4) also boosts memory formation in aged pond snails. Due to the evolutionarily conserved nature of these polypeptides and their established role in memory and synaptic plasticity, there is a very high probability that they could also act as "memory rejuvenating" agents in humans. © The Author 2014.

    The OECD test guideline development program has been extended in 2011 to establish a partial life-cycle protocol for assessing the reproductive toxicity of chemicals to several mollusk species, including the great pond snail Lymnaea stagnalis. In this paper, we summarize the standard draft protocol for a reproduction test with this species, and present inter-comparison results obtained in a 56-day prevalidation ring-test using this protocol. Seven European laboratories performed semi-static tests with cultured snails of the strain Renilys® exposed to nominal concentrations of cadmium chloride (from 53 to 608μgCdL(-1)). Cd concentrations in test solutions were analytically determined to confirm accuracy in the metal exposure concentrations in all laboratories. Physico-chemical and biological validity criteria (namely dissolved oxygen content >60% ASV, water temperature 20±1°C, control snail survival >80% and control snail fecundity >8 egg-masses per snail over the test period) were met in all laboratories which consistently demonstrated the reproductive toxicity of Cd in snails using the proposed draft protocol. Effect concentrations for fecundity after 56days were reproducible between laboratories (68

    The pond snail Lymnaea stagnalis learns and forms long-term memory (LTM) following both operant conditioning of aerial respiratory behavior and classical conditioning of taste aversive behavior. In the present study, we examined whether there are interstrain differences in the ability to form LTM following these two types of conditioning. A strain of Lymnaea (TC1) collected in Alberta, Canada exhibits superior memory-forming ability following aerial respiratory operant conditioning compared to a laboratory-reared strain of Lymnaea from Netherlands known as the Dutch strain. We asked whether the offspring of the Canadian TC1 and Dutch snails (i.e., filial 1 (F 1 ) cross snails) would have the superior memory ability and found, rather, that their memory ability was average like the Dutch snails. That is, the Canadian TC1 snails have superior ability for LTM formation following aerial respiratory operant conditioning, but the Dutch and the generated F 1 cross have average ability for memory forming. We next examined the Canadian TC1, Dutch and F 1 cross snails for their ability to learn and form memory following conditioned taste aversion (CTA). All three populations showed similar associative CTA responses. However, both LTM formation and the ratio of good-to-poor performers in the memory retention test were much better in the Dutch snails than the Canadian TC1 and F 1 cross snails. The memory abilities of the Canadian TC1 and F 1 cross snails were average. Our present findings, therefore, suggest that snails of different strains have different memory abilities, and the F 1 cross snails do not inherit the memory ability from the smart strain. To our knowledge, there have been a limited number of studies examining differences in memory ability among invertebrate strains, with the exception of studies using mutant flies.

  7. Facilitating consumer participation: an approach to finding the 'right' consumer.

    Science.gov (United States)

    Happell, Brenda

    2010-01-01

    Contemporary health care increasingly dictates that consumers of services should become active participants in the health care system. This has placed responsibility on administrators, managers and clinicians to include consumers in key strategic and decision making initiatives. However, this direction has not been accompanied by clear policies or guidelines. Consequently confusion about selecting consumers able to provide valuable input is identified as a barrier to active consumer involvement. The purpose of this paper is to address some concerns raised in the quest to find the "right" consumer, including: finding a consumer without an axe to grind; ensuring the consumer is representative of broader views; health professionals as consumer representatives. While these concerns are common they have not yet been extensively debated and discussed in the broader Literature. Strategies necessary to support consumers in participatory roles are also considered and the controversial subject of financial remuneration for consumers is also explored.

    Doenjang is a traditional Korean food and is widely used for many Korean foods. Consumer perception and consumer acceptability on the typical sensory characteristics of traditional Doenjang remain unknown. The objective of the current study was to determine the consumer perception on traditional Doenjang characteristics and how preexisting consumer perception influenced the consumer liking for traditionally and commercially manufactured Doenjang. A consumer survey was conducted by presenting 26 sensory descriptions to consumers (n = 82) for check-all-that-apply measurement. Then, a consumer acceptance test was conducted over 2 d on 2 Doenjang samples representing commercially produced Doenjang and traditionally produced Doenjang: Day 1 consumers evaluated without any information (n = 182), and day 2 consumers evaluated samples informed that both samples were made by the "traditional" method (n = 109). Two-way ANOVA and multivariate analyses were conducted. Consumers' preexisting perceptions on the typical sensory characteristics of traditionally made Doenjang were similar in that they associate "gu-soo flavor," "dark color," "flavorful," and "well-fermented flavor" regardless of consumer demographics and Doenjang user status. However, these consumer perceptions on sensory attributes of traditional Doenjang did not agree with desirable sensory attributes for consumer liking, in that consumers preferred the commercially made Doenjang regardless of the evaluation condition and consumer user status. Findings from the current study therefore suggested a discrepancy between the preexisting current consumer perception and actual consumer acceptability of traditional Doenjang products. © 2014 Institute of Food Technologists®

  9. MEASUREMENT OF CONSUMER ETHNOCENTRISM OF SLOVAK CONSUMERS

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available The conceptualization of consumer ethnocentrism is inferred from the general concept of ethnocentrism which assumes that ethnocentrism starts with the culture into which an individual is born. Over time, the individual will accept the values and behaviour of this particular culture as a norm. However, when the individual becomes aware of other cultures with different values and behaviours, there develops the need of belonging and identification with own culture rather than that of others. When analysing the consumer ethnocentrism, it is also essential to examine whether consumer ethnocentrism operates uniformly across all consumers or there exist some specific factors moderating their ethnocentric tendencies. A lot of studies researching these issues can be found in various cultural contexts, however in Slovakia we found certain gap since there is just a few of them. The aim of the paper is to investigate the level of consumer ethnocentricity of Slovak consumers in general and with the respect to chosen variables – age and gender. The results can serve as an information base for decision-making process of marketing managers focusing especially on local production of domestic products.

    2003-01-01

    There has been a proliferation of health care consumer reports, also known as "consumer guides," "report cards," and "performance reports," which are designed to assist consumers in making more informed health care decisions. While there is evidence that providers use such reports to identify and make changes in practice, thus improving the quality of care, there is little empirical evidence on how consumer guides/report cards are used by consumers. This study fills that gap by surveying 925 patients as they wait for ambulatory care in several clinics in a midwestern city. Findings indicate that consumers are selective in their use of these reports and quickly identify those sections of the report of most interest to them. Report developers should take precautions to ensure such reports are viewed as credible sources of health care information.

    Historically, people living with mental illness have had limited chance to participate in mental health services other than as patients. Following on from a recent review focusing on consumer participation in mental health services, this paper looks at consumer participation in housing. Housing is a critical element in recovery from mental illness. Without suitable housing, people have little chance of maintaining other resources in their lives, such as supportive social relationships and meaningful activities. Consumer participation is not a common topic in the recent literature, despite the significant public policy push to promote it. The importance of appropriate housing to the recovery of people living with mental illness cannot be underestimated. Even well-meaning and well-resourced housing initiatives can fall short of meeting consumers' recovery goals when they do not incorporate the expressed needs of consumers. These expressed needs include keeping units small in size and employing drop-in support models.

    2017-01-01

    This paper uses consumer health informatics as a framework to explore whether and how direct-to-consumer personal genomic testing can be regarded as a form of information which assists consumers to manage their health. It presents findings from qualitative content analysis of web sites that offer testing services, and of transcripts from focus groups conducted as part a study of the Australian public's expectations of personal genomics. Content analysis showed that service offerings have some features of consumer health information but lack consistency. Focus group participants were mostly unfamiliar with the specifics of test reports and related information services. Some of their ideas about aids to knowledge were in line with the benefits described on provider web sites, but some expectations were inflated. People were ambivalent about whether these services would address consumers' health needs, interests and contexts and whether they would support consumers' health self-management decisions and outcomes. There is scope for consumer health informatics approaches to refine the usage and the utility of direct-to-consumer personal genomic testing. Further research may focus on how uptake is affected by consumers' health literacy or by services' engagement with consumers about what they really want.

  16. Pituitary adenylate cyclase activating polypeptide (PACAP) and its receptors are present and biochemically active in the central nervous system of the pond snail Lymnaea stagnalis.

    PACAP is a highly conserved adenylate cyclase (AC) activating polypeptide, which, along with its receptors (PAC1-R, VPAC1, and VPAC2), is expressed in both vertebrate and invertebrate nervous systems. In vertebrates, PACAP has been shown to be involved in associative learning, but it is not known if it plays a similar role in invertebrates. To prepare the way for a detailed investigation into the possible role of PACAP and its receptors in a suitable invertebrate model of learning and memory, here, we undertook a study of their expression and biochemical role in the central nervous system of the pond snail Lymnaea stagnalis. Lymnaea is one of the best established invertebrate model systems to study the molecular mechanisms of learning and memory, including the role of cyclic AMP-activated signaling mechanisms, which crucially depend on the learning-induced activation of AC. However, there was no information available on the expression of PACAP and its receptors in sensory structures and central ganglia of the Lymnaea nervous system known to be involved in associative learning or whether or not PACAP can actually activate AC in these ganglia. Here, using matrix-assisted laser desorption ionization time of flight (MALDI-TOF) and immunohistochemistry, we established the presence of PACAP-like peptides in the cerebral ganglia and the lip region of Lymnaea. The MALDI-TOF data indicated an identity with mammalian PACAP-27 and the presence of a squid-like PACAP-38 highly homologous to vertebrate PACAP-38. We also showed that PACAP, VIP, and maxadilan stimulated the synthesis of cAMP in Lymnaea cerebral ganglion homogenates and that this effect was blocked by the appropriate general and selective PACAP receptor antagonists.

    During extrusion of the first polar body in eggs ofLymnaea stagnalis andBithynia tentaculata a localized Ca 2+ /Mg 2+ ATPase activity was detected, using Ando's enzyme-cytochemical method for electron microscopy [Ando et al. (1981) Acta Histochem Cytochem 14:705-726]. The enzyme activity was distributed in a polar fashion, along the cytoplasmic face of the plasma membrane. In the eggs ofLymnaea it was found only in the vegetal hemisphere, whereas inBithynia eggs it was localized both in the vegetal hemisphere and at the animal pole. This pattern of enzyme activity corresponds to the polar pattern of transcellular ionic currents measured with the vibrating probe, which we showed to be partially carried or regulated by calcium [Zivkovic and Dohmen (1989) Biol Bull (Woods Hole) 176 (Suppl):103-109]. The characteristics of the ATPase were studied using a variety of approaches such as ion and substrate depletions and substitutions, addition of specific inhibitors of ATPase activity, treatment with EDTA/EGTA and electron energy-loss spectrometry. The results indicate that, inLymnaea, there are at least two enzymatic entities. The first one is a Ca 2+ /Mg 2+ ATPase localized along the membrane and in the cortex of the vegetal hemisphere. The second one is a Ca 2+ -stimulated ATPase (calcium pump of the plasma membrane) localized in a small region of the membrane at the vegetal pole. We speculate that in the eggs ofLymnaea andBithynia a functional relationship exists between the plasma-membrane-associated ATPase activity and the transcellular ionic currents measured in the same region.

To evaluate the association between variables, the Pearson correlation test is used, and then to verify the conceptual model test the structural equation modeling (SEM and LISREL software are deployed. The result shows that Value congruity positively influences consumers' identification with a brand and Value congruity positively influences consumers ‘commitment to brand. The result also shows that Consumer identification has a positive influence on brand commitment and mediating variable between value congruity and brand commitment and Consumers commitment to a brand has a positive influence on positive WOM and mediating variable between consumers' identification and WOM. The results also demonstrate that Consumer identification positively influences positive WOM.

    Direct-to-consumer (DTC) genetic tests can be purchased over the internet. Some companies claim to provide relative genetic risks for various diseases and thus encourage healthy behaviour. There are concerns that exposure to such information may actually discourage healthy behaviour or increase health anxiety. An online survey was conducted (n = 275). Respondents were composed of individuals who had purchased a DTC genetic test and received their results (consumers, n = 189), as well as individuals who were either awaiting test results or considering purchasing a test (potential consumers, n = 86). Consumers were asked if their health behaviour or health anxiety had changed after receiving their results. Respondents' current health behaviour and health anxiety were queried and compared. In total, 27.3 % of consumers claimed a change in health behaviour, all either positive or neutral, with no reported cessation of any existing health behaviour. A change in health anxiety was claimed by 24.6 % of consumers, 85.3 % of which were a reduction. Consumers had significantly better health behaviour scores than potential consumers (p = 0.02), with no significant difference in health anxiety. This study points towards an association between receipt of DTC genetic test results and increased adoption of healthy behaviours for a minority of consumers based on self-report, with more mixed results in relation to health anxiety.

  12. Effects of chronic waterborne nickel exposure on growth, ion homeostasis, acid-base balance, and nickel uptake in the freshwater pulmonate snail, Lymnaea stagnalis.

    The freshwater pulmonate snail, Lymnaea stagnalis, is the most sensitive aquatic organism tested to date for Ni. We undertook a series of experiments to investigate the underlying mechanism(s) for this observed hypersensitivity. Consistent with previous experiments, juvenile snail growth in a 21-day exposure was reduced by 48% relative to the control when exposed to 1.3 μg l(-1) Ni (EC20 less than the lowest concentration tested). Ca(2+) homeostasis was significantly disrupted by Ni exposure as demonstrated by reductions in net Ca(2+) uptake, and reductions in Ca(2+) concentrations in the hemolymph and soft tissues. We also observed reduced soft tissue [Mg(2+)]. Snails underwent a significant alkalosis with hemolymph pH increasing from 8.1 to 8.3 and hemolymph TCO2 increasing from 19 to 22 mM in control versus Ni-exposed snails, respectively. Unlike in previous studies with Co and Pb, snail feeding rates were found to be unaffected by Ni at the end of the exposure. Snails accumulated Ni in the soft tissue in a concentration-dependent manner, and Ni uptake experiments with (63)Ni revealed a biphasic uptake profile - a saturable high affinity component at low exposure concentrations (36-189 nM) and a linear component at the high exposure concentrations (189-1,897 nM). The high affinity transport system had an apparent Km of 89 nM Ni(2+) and Vmax of 2.4 nmol g(-1)h(-1). This equates to a logK of 7.1, significantly higher than logK's (2.6-5.2) for any other aquatic organisms evaluated to date, which will have implications for Biotic Ligand Model development. Finally, pharmacological inhibitors that block Ca(2+) uptake pathways in snails did not inhibit Ni uptake, suggesting that the uptake of Ni does not occur via Ca(2+) uptake pathways. As with Cu and Pb, the exact mechanism for the significant disruption in Ca(2+) homeostasis and reduction in juvenile snail growth remains unknown. Copyright © 2014 Elsevier B.V.

However, the era of technological change also means developing biotechnologies, nanotechnologies, new materials and new energy sources, all these changing people`s lives, living conditions, their needs and their behaviour as consumers. The literature highlights the factors that influence purchasing behaviour and changes manifested in terms of values, stressing the importance of promoting and protecting consumer`s rights and interests, The new responsible consumer can become a key driving force of sustainable development only if it is able to capitalize on new opportunities and to counter new risks of modern marketing technologies based on the Internet and mobile communications. This involves the assimilation of new knowledge throughout life to keep up with the accelerating pace of technological innovation and diffusion of e-commerce solutions and mobile commerce. We study the correlation between the composite index of consumer conditions and the level of participation in lifelong learning programmes in some Member States, based on secondary analysis of the data available at EU level,. The results confirm that the consumer`s situation is better in countries where the level of participation in lifelong learning programmes is higher. At the same time, however, the correlation is not linear. This shows that the consumer`s situation does not depend exclusively on formal continuing education but also other factors such as timeliness and severity of legal and institutional framework of consumer protection, the acquisition of knowledge through informal means, the requirement of different customers in different

    Full Text Available       This paper outlines the results of consumer research to investigate consumer attitudes towards olive oil, and to evaluate selected experimental samples for acceptability.
          Consumer focus group discussions were used to investigate consumer attitudes to and awareness of olive oil, in relation to other culinary oils. A wide range of information was obtained, indicating the increasing importance of olive oil in the UK.
           Product use was examined to investigate the different types of olive oils consumers use, and the importance of different attributes for purchase. Price, quality and colour were the most important considerations for purchasing an olive oil, whilst package design, package material and brand were the least important.       Eight samples of virgin olive oil were evaluated for acceptability of appearance, odour, flavour and mouthfeel. These data indicated clear differences in acceptability between the samples, particularly on flavour, mouthfeel and overall acceptability. These data were then linked to sensory information to determine the characteristics of oil associated with liking for the product.

    Direct-to-consumer advertising (DTCA) of prescription drugs in the United States is controversial. Underlying the debate are disagreements over the role of consumers in medical decision making, the appropriateness of consumers engaging in self-diagnosis, and the ethics of an industry promoting potentially dangerous drugs. Drug advertising and federal policy governing drug advertising have both responded to and reinforced changes in the consumer's role in health care and in the doctor-patient relationship over time. This article discusses the history of DTCA in the context of social movements to secure rights for health care patients and consumers, the modern trend toward consumer-oriented medicine, and the implications of DTCA and consumer-oriented medicine for contemporary health policy debates about improving the health care system.

  1. LOW INCOME CONSUMERS AND ONLINE SHOPPING: APPREHENSIONS IN CONSUMING THROUGH THE INTERNET

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available The growth in access of low income consumers to the internet has taken them to use the net in search of entertainment, education and relationships. However, consuming online is still an activity surrounded by distrust. The present study aims to discuss the reasons why low income consumers have apprehension in consuming through the internet. For this, in depth interviews were conducted with 23 low income consumers. The collected data shows that the internet is still seen by the interviewees as being, mainly, for leisure and entertainment. Online shopping still is a task they fear, because of different motives. Initially, one can point the preference to consume in physical stores, since the consumers can touch the desired product, enjoy the trip to the store as a moment of pleasure and the possibility of interacting with salesmen, who help them in their choice. The apprehensions in buying online are also influenced by the perception that sites are not safe, because they offer threats, such as viruses or theft of personal information. Furthermore, interviewees believe that online stores are not compromised with their customers, since they permit problems to occur in the delivery of merchandise, are not clear about the shopping process, and create difficulties in payment method. Another reason for them not to buy online is the perception that if a negative consuming episode of online shopping happened to someone they know, it is also bound to happen with them. Despite this reasoning, these consumers point the importance of help from a third party in their reference group as main incentive for them to face the obstacles to consuming through the internet. In conclusion, it is possible to consider that low income consumers have apprehensions that are similar to their higher income peers, but, also, show different feelings, which are seldom discussed in the literature about online shopping.

    The objectives of this study were to: identify government policies for reducing Canadian consumption of home heating fuel, electricity, and gasoline; assess probable effectiveness of different policy alternatives as a means of reducing consumer energy consumption; and measure the acceptability to Canadian consumers of the different policy alternatives. Interviews were conducted with energy conservation professionals to identify and evaluate existing energy conservation programs, and interviews were conducted with consumers who had evaluated selected programs previously reviewed by the professionals. Information was also gathered on energy conservation activities of consumers surveyed. A directory of 34 energy conservation programs was also compiled. Some of the conclusions reached in this report are as follows. There is a need for an information system to gather data on existing conservation programs in order to increase the knowledge of relevant parties as to the outcomes of operating programs. This would help evaluation and improvement of current programs and suggest new program possibilities. The professionals rated six of the 34 programs highly, including the Energuide and the Canadian Home Insulation Program (CHIP). Retrofitting programs for houses are recommended for continuation and expansion, with some consideration given to linking these kinds of programs with home audit programs. In the private transport sector, any new conservation programs should be thoroughly tested on a small scale before widespread implementation, as evidence indicates that certain programs favorably evaluated by professionals may not be received favorably by consumers. 3 refs., 24 tabs.

    Full Text Available The paper analyses the notion of consumer in the European Union law, and, in particular, the notion of consumer in insurance law. The author highligts the differences between the notion of consumer is in aquis communautaire and in insurance law, discussing whether the consumer can be defined in both field in the same way, concerning that insurance services differ a lot from other kind of services. Having regarded unequal position of contracting parties and information and technical disadvantages of a weaker party, author pleads for broad definition of consumer in insurance law. In Serbian law, the consumer is not defined in consistent way. That applies on Serbian insurance law as well. Therefore, the necessity of precise and broad definition of consumes is underlined, in order to delimit the circle of subject who are in need for protection. The author holds that the issue of determination of the circle of persons entitled to extended protection as consumers is of vital importance for further development of insurance market in Serbia.

    Full Text Available The aim of this study was to analyze the influence of greenwshing in consumer awareness for green consumption in retail. Under this approach was evaluated if the greenwashing confuses consumers about what is to be green consumption and if it relies on green consumption. For the verification of the objective proposed by this work, an exploratory survey was conducted quantitative, through a survey with a sample of 359 respondents of São Paulo/Brazil. As for the justification of the method used, the exploratory research, with a non-probabilistic convenience sampling and quantitative nature, are characterized by a field approach seeking situational characteristics presented by respondents to generate quantitative measures of the attributes observed by them. For data collection was used a specialized company and market research and thus were collected data from real consumers. As a result it was observed that the greenwashing confuses consumed and does not influence the confidence of the green product.

  14. Optimal Consumer Electronics Product Take-Back Time with Consideration of Consumer Value

    Full Text Available Rapid economic growth in recent years has transformed our lifestyle to massively produce, consume, and dispose of products, especially for consumer electronics. This change has put great threat to our environment and caused natural resource depletion. Moreover, short product life cycles and quick replacements of consumer electronics create enormous electronic wastes (e-wastes. Without proper waste management, immense environmental damage is expected. In this empirical study, we notice that lots of valuable materials that can still be recycled from these used consumer electronics are left unused at home instead of being recycled at the appropriate time, which causes a low collection rate and a decrease in residual value for the used products. Therefore, it is important for the government and the recyclers to handle them efficiently by increasing the used product take-back rate. Our study develops an assessment model for customer value based on the idea of value engineering and the perspective of product life cycle. We also explore the relationship between product value and the total cost of ownership with an evaluation of their time variation, considering different usage modes for various consumer groups and different recycling award schemes (fixed and variable recycling awards. Proper take-back management is likely to create a win-win situation both for consumers and environmental protection. This study regards the notebook computer as an example to determine the optimal time for recycling laptops based on usage patterns and provides consumers a reference for when to replace their used product. The results from our modeling firstly clearly indicate that consumers with higher frequency of usage have shorter take back times and higher maximum consumer value. Secondly, a variable recycling award scheme with higher maximum consumer value is more practical than a fixed recycling award scheme.

  15. Consumer identification with store brands: Differences between consumers according to their brand loyalty

    2015-04-01

    Full Text Available Retail management of store brands (SBs has focused on achieving positioning in value and creating associations of smart or expert shopping. The result is that value-conscious consumers and market mavens are the main targets of these brands. This study proposes and contrasts empirically a theoretical model of the effect of market mavenism and value consciousness on consumer identification with SBs. We also perform a multi-group analysis based on the consumer tendency to be loyal to the brands he or she buys. Consumers who are loyal to brands are very attractive segments for firms, due to the potential benefits these consumers represent in the long term, whereas consumers with little loyalty to brands can be an attractive segment for potential benefits in the short term. The results obtained in this study show differences between these two groups. For consumers who are loyal to brands, the results stress strong identification with the SB among the most value-conscious consumers, due fundamentally to their greater disagreement with the greater functional risk of these brands as compared to manufacturer brands and due to their greater conviction of the better price-quality ratio of SBs. In consumers with little brand loyalty, we find identification with the SB among the consumers with the greatest market mavenism, as a result of their greater perception of smart or expert shopping for these brands. Significant implications for management are derived from this study.

    Full Text Available Complaining is one form of communication for consumers to express their dissatisfaction. Understanding the consumer complaint behavior is an important thing for businesses; however, it is not easy to do. The initial step in understanding this behavior of consumer complaints is to map consumers based on their behavior of complaints and analyze the factors that influence this. This study examines the complaint behavior of consumers in Cibubur who have experienced dissatisfaction with a product.  The objectives of this study are to map the consumer complaint behavior and identify its relationship with various factors such as consumer demographics, personality, attitude to businesses, attribution of the causes of dissatisfaction, and product attributes. A crosstab descriptive analysis method was used to map the consumers, while the Pearson correlation analysis methods was used to analyze consumer complaint behavioral relationships with various factors. The results of this study indicated that consumers in Cibubur based on their complaint behavior are classified into four groups: passive, voicers, irates and activist. The passive consumers dominate the category with a percentage of 49%.  The voicers, irates, and activist belong to the complaining type and are dominated by young women, with high levels of education and income.

    2013-05-01

    Full Text Available The right of withdrawal (of a contract belongs to the consumer, and is an essential means for the improvement of regulations that protect the consumer.. Right of withdrawal is not a recent creation and is not even specific to the consumer field. He was previously recognized in civil and commercial law (without special regulation. The right to withdraw may even have as ground the parties will. Thus, based on the contractual freedom, the parties may agree that one of them has the right to terminate the contract unilaterally The possibility of unilateral denunciation of the contract, gives the consumer, added protection by being able to reflect the decision and to check how the trader fulfil its obligations. In this context, through its effects, the right of denunciation, forces the professional parties to conduct themselves as fair as possible to the consumer and to execute the contract properly. In the study of the consumer protection, the time of conclusion is essential because in this stage is manifested, the inequality between the consumer and professional. Thus, the lack of information, the major of products and activities, commercial practices, influence the formation of consumer will, preventing the expression of a freely and knowingly consent.

  1. The Effect of Diet Mixing on a Nonselective Herbivore.

    Directory of Open Access Journals (Sweden)

    Sophie Groendahl

    Full Text Available The balanced-diet hypothesis states that a diverse prey community is beneficial to consumers due to resource complementarity among the prey species. Nonselective consumer species cannot differentiate between prey items and are therefore not able to actively regulate their diet intake. We thus wanted to test whether the balanced-diet hypothesis is applicable to nonselective consumers. We conducted a laboratory experiment in which a nonselective model grazer, the freshwater gastropod Lymnaea stagnalis, was fed benthic green algae as single species or as a multi-species mixture and quantified the snails' somatic growth rates and shell lengths over a seven-week period. Gastropods fed the mixed diet were found to exhibit a higher somatic growth rate than the average of the snails fed single prey species. However, growth on the multi-species mixture did not exceed the growth rate obtained on the best single prey species. Similar results were obtained regarding the animals' shell height increase over time. The mixed diet did not provide the highest growth rate, which confirms our hypothesis. We thus suggest that the balanced-diet hypothesis is less relevant for non-selective generalist consumers, which needs to be considered in estimates of secondary production.

    Full Text Available To ensure that consumers understand financial products’ “costs, benefits, and risks,” the Consumer Financial Protection Bureau has been redesigning mandated disclosures, primarily through iterative lab testing. But no matter how well these disclosures perform in experiments, firms will run circles around the disclosures when studies end and marketing begins. To meet the challenge of the dynamic twenty-first-century consumer financial marketplace, the bureau should require firms to demonstrate that a good proportion of their customers understand key pertinent facts about the financial products they buy. Comprehension rules would induce firms to inform consumers and simplify products, tasks that firms are better equipped than the bureau to perform.

  4. Health care knowledge and consumer learning: the case of direct-to-consumer drug advertising.

    Science.gov (United States)

    Delbaere, Marjorie; Smith, Malcolm C

    2006-01-01

    This research develops a framework for understanding how consumers process health-related information and interact with their caregivers. The context is direct-to-consumer (DTC) advertising by pharmaceutical companies in North America. This theoretical research presents a research framework and focuses on the presentation of information in advertisements, consumer-learning processes, consumer utilization of health care knowledge, and bias in perceived risk. The paper proposes that consumers who lack expertise with prescription drugs learn from DTC ads differently than those with expertise. Further, it is proposed that consumers also process the information in DTC ads differently depending on the perceived effectiveness of the drug being advertised, and ultimately utilize the knowledge taken from the ads in many different ways, some of which may appear irrational to health care providers. By understanding how consumers interpret and learn from DTC ads, health care organizations and providers may be able to improve health care delivery and consumer outcomes.

    Evaluating chemical exposures from consumer products is an essential part of chemical safety assessments under REACH and may also be important to demonstrate compliance with consumer product legislation. Modelling of consumer exposure needs input information on the substance (e.g. vapour pressure), the product(s) containing the substance (e.g. concentration) and on consumer behaviour (e.g. use frequency and amount of product used). This feasibility study in Germany investigated methods for conducting a consumer survey in order to identify and retrieve information on frequency, duration, use amounts and use conditions for six example product types (four mixtures, two articles): hand dishwashing liquid, cockpit spray, fillers, paints and lacquers, shoes made of rubber or plastic, and ball-pens/pencils. Retrospective questionnaire methods (Consumer Product Questionnaire (CPQ), and Recall-Foresight Questionnaire (RFQ)) as well as protocol methods (written reporting by participants and video documentation) were used. A combination of retrospective questionnaire and written protocol methods was identified to provide valid information in a resource-efficient way. Relevant information, which can readily be used in exposure modelling, was obtained for all parameters and product types investigated. Based on the observations in this feasibility study, recommendations are given for designing a large consumer survey.

    Full Text Available The consumer is that trader responsible for consumption act of some final goods or services who decided what must be produce and in what cantity, being the one who make the economic mechanism to move. Consumption is in close connection with the production of goods and services, exerting an active role, any activity should be complete by consuming its results; consumption creates the motivation to achieve economic and non-economic activities. The traditional approach to consumer behavior starts from hypothesised that all consumers seek to maximize the aggregate utility obtained of satisfactions resulting from consumption of goods taking into account the budgetary constraints given by income that consumer has and the prices of these goods. In the conditions of modern economy, consumption can be increased by diseconomies. If consumption depends on permanent income, revenue growth effectively does not exert influence on consumption only to the extent that this increase of income leads to increasing permanent income consumer. Consumption is viewed as an active agent of economic life, it is not only a consumer of goods and services but also a producer.

    Contemporary EU food information legislation combines and balances two main consumer interests, i.e., a consumer right to information and the freedom of choice, into one single protective standard: informed choice. Although the recent legislative measures quite openly establish a link between...... informed choice and the rather abstract societal norm of “what is good for the consumer,” this does not justify the conclusion that food information legislation has become overly meddlesome in relation to EU consumers and their choice of food. Rather, there has been a gradual maturing of the EU legislator......’s perception of its task from the mere provision of food information to ensuring educated consumer choices.

It is then followed by the clustering of female consumers of skin moisturizer based on ethnocentrism and differentiating each cluster’s consumer-based brand equity dimensions towards a domestic skin moisturizer brand Mustika Ratu, skin moisturizer. Research used descriptive survey method analysis. Primary data was obtained through questionnaire distribution to 70 female respondents for factor analysis and 120 female respondents for cluster analysis and one way analysis of variance (ANOVA. This research employed factor analysis to obtain relevant factors contributing to the five dimensions of consumer-based brand equity in skin moisturizer industry. Cluster analysis and one way analysis of variance (ANOVA were to see the difference of consumer-based brand equity between highly ethnocentric consumer and low ethnocentric consumer towards the same skin moisturizer domestic brand, Mustika Ratu skin moisturizer. Research found in all individual dimension analysis, all variable means and individual means show distinct difference between the high ethnocentric consumer and the low ethnocentric consumer. The low ethnocentric consumer cluster tends to be lower in mean score of Brand Loyalty, Perceived Quality, Brand Awareness, Brand Association, and Overall Brand Equity than the high ethnocentric consumer cluster. Research concludes consumer ethnocentrism is positively correlated with preferences towards domestic products and negatively correlated with foreign-made product preference. It is, then, highly ethnocentric consumers have positive perception towards domestic product.

  10. Materialism, status consumption, and consumer independence.

    Science.gov (United States)

    Goldsmith, Ronald Earl; Clark, Ronald A

    2012-01-01

    Materialism influences many people. We focus on two aspects of this influence: reactions to prestige products and to the influence of others. A study of 187 U.S. student consumers shows that materialism is positively related to buying products that confer status. In contrast, materialism is negatively related to consumer independence, an enduring tendency to pay minimal attention to the prescribed norms of other consumers and to make product and brand decisions according to personal preferences. Consuming products for status is also negatively related to consumer independence. Moreover, the association between materialism and consumer independence is completely mediated by consuming for status. Materialism urges consumers to be status conscious so that they follow social norms in purchasing, but seeking status through goods is avoided by less materialistic, independent consumers. A second study (n = 258) also using student consumers confirmed these results.

    Both doctors and consumers have engaged in using social media for health purposes. Social media has changed traditional one-to-one communication between doctors and patients to many-to-many communication between doctors and consumers. However, little is known about the effect of doctor-consumer interaction on consumers' health behaviors. The aim of this study was to investigate how doctor-consumer interaction in social media affects consumers' health behaviors. On the basis of professional-client interaction theory and social cognitive theory, we propose that doctor-consumer interaction can be divided into instrumental interaction and affective interaction. These two types of interactions influence consumers' health behaviors through declarative knowledge (DK), self-efficacy (SE), and outcome expectancy (OE). To validate our proposed research model, we employed the survey method and developed corresponding measurement instruments for constructs in our research model. A total of 352 valid answers were collected, and partial least square was performed to analyze the data. Instrumental doctor-consumer interaction was found to influence consumers' DK (t 294 =5.763, Pinteraction also impacted consumers' DK (t 294 =4.025, Pinteraction on health behaviors, whereas the three mediators fully mediated the effect of affective interaction on health behaviors. Compared with many intentional intervention programs, doctor-consumer interaction can be treated as a natural cost-effective intervention to promote consumers' health behaviors. Meanwhile, both instrumental and affective interaction should be highlighted for the best interaction results. DK, SE, and OE are working mechanisms of doctor-consumer interaction. ©Tailai Wu, Zhaohua Deng, Zhanchun Feng, Darrell J Gaskin, Donglan Zhang, Ruoxi Wang.

    Bread contains a wide range of important nutritional components which provide a positive effect on human health. However, the consumption of bread is declining during the last decades. This is due to factors such as changing eating patterns and an increasing choice of substitutes like breakfast cereals and fast foods. The aim of this study is to investigate consumer's quality perception of bread towards sensory, health and nutrition attributes. Four consumer segments are identified based on these attributes. The different consumer segments comprise consumers being positive to all three quality aspects of bread ("enthusiastic") as wells as consumers perceiving bread strongly as "tasteless", "non-nutritious" or "unhealthy". Moreover, factors are identified which influence the consumers' quality perception of bread. The results of our study may help health professionals and policy makers to systematically inform consumers about the positive effects of bread based on its components. Furthermore, firms can use the results to build up tailor-made marketing strategies.

  9. Impact of scarcity on consumer behavior

    Directory of Open Access Journals (Sweden)

    T.U. Kulakovsky

    2016-09-01

    Full Text Available This article analyzes the impact of scarcity on consumer behavior and on perception of scarce goods consumer qualities. The author examines and subjects to the critical analysis the impact of scarcity on consumer behavior within economic theory, the theory of reactance and commodity theory. The differences in explaining the impact of scarcity on consumer behavior in economic and psychological sciences is highlighted. The current researcher experimentally proves the impact of the scarcity as an isolated factor on consumer behavior and the impact of scarcity on consumer perception of product quality. According to the reactance theory, an individual perceives scarcity as the restriction of his freedom that causes resistance in response to a possible restriction of freedom of actions. This reinforces the desire to have such a scarce product. To confirm the psychological impact of scarcity on a domestic consumer the author designs and conducts the experiment that confirms the following hypotheses: scarcity affects consumer behavior and stimulates consumers to purchase scarce commodities; scarcity has impact on the perception of scarce product consumer qualities. Such consumer behavior relatively to scarce goods can be used by marketers to promote products on the market.

  10. High dietary quality of non-toxic cyanobacteria for a benthic grazer and its implications for the control of cyanobacterial biofilms.

    Groendahl, Sophie; Fink, Patrick

    2017-05-18

    Mass occurrences of cyanobacteria frequently cause detrimental effects to the functioning of aquatic ecosystems. Consequently, attempts haven been made to control cyanobacterial blooms through naturally co-occurring herbivores. Control of cyanobacteria through herbivores often appears to be constrained by their low dietary quality, rather than by the possession of toxins, as also non-toxic cyanobacteria are hardly consumed by many herbivores. It was thus hypothesized that the consumption of non-toxic cyanobacteria may be improved when complemented with other high quality prey. We conducted a laboratory experiment in which we fed the herbivorous freshwater gastropod Lymnaea stagnalis single non-toxic cyanobacterial and unialgal diets or a mixed diet to test if diet-mixing may enable these herbivores to control non-toxic cyanobacterial mass abundances. The treatments where L. stagnalis were fed non-toxic cyanobacteria and a mixed diet provided a significantly higher shell and soft-body growth rate than the average of all single algal, but not the non-toxic cyanobacterial diets. However, the increase in growth provided by the non-toxic cyanobacteria diets could not be related to typical determinants of dietary quality such as toxicity, nutrient stoichiometry or essential fatty acid content. These results strongly contradict previous research which describes non-toxic cyanobacteria as a low quality food resource for freshwater herbivores in general. Our findings thus have strong implications to gastropod-cyanobacteria relationships and suggest that freshwater gastropods may be able to control mass occurrences of benthic non-toxic cyanobacteria, frequently observed in eutrophied water bodies worldwide.

  11. A garland for consumers: Will the Garland case provide safeguards for vulnerable consumers?

    International Nuclear Information System (INIS)

    Reid, H.

    2000-01-01

    In Garland versus Consumer Gas, the Supreme Court of Canada in October 1998 ruled that the late payment penalties (LPP) charged by Consumer Gas constitute a criminal interest rate, contrary to Section 347 of the Criminal Code. The decision was unexpected in as much as the LPP had been continuously approved by the Ontario Energy Board since its adoption in 1975. This case is used here as an illustration of how consumers, who possess little bargaining power, may be protected from usurious penalties and charges for late payment. An examination of the legislative history surrounding the adoption of Section 347 of the Criminal Code, and a review of relevant Canadian case law with emphasis on the Supreme Court's reasoning with respect to the LPP in the Garland case, is followed by a comparison of Canadian experience with consumer protection in the United States and the United Kingdom. Policy implications of the Garland case from a consumer perspective are examined in general, and in terms of various industries as may be found in policy statements of specific companies. Recommendations are offered suggesting actions that may be taken to further protect consumers from exploitative credit arrangements.48 refs

The consumer attitudes have long been discussed and written about. For this purpose, numerous theories, models and researches have emerged. The research of powerful feelings of consumers towards products is something that marketers are constantly trying to achieve. Therefore it is very important for them to understand the factors affecting the attitudes of consumers. Issues related to consumers' attitudes have always been subject matter of the marketers who are trying to keep and maintain the positive and minimize negative attitudes towards the products and services of company.

    Growing consumer awareness of functional foods and understanding of their positive nutritional effects have led to the need of specific studies and have captured more attention than ever before. In Europe, Danish consumers have been found to be relatively negative towards the concept of functional foods. This paper presents the results of a qualitative pilot study that aimed to explore Danish consumers' motives for choosing omega-3/fish oil enriched products. The Health Action Process Approach (HAPA) was applied as a theoretical framework to understand the process by which people choose healthy foods. By conducting qualitative in-depth interviews the study mostly focused on the role of behavioural intention predictors such as risk perception, outcome expectations and self-efficacy. The results of the study suggest that consumers' understanding of healthy eating as such does not relate to the choice of omega-3/fish oil, whereas perception of omega-3 as an ingredient in selected foods does indeed influence consumers' choice of carrier-ingredient combinations.

  18. Consumer choice: Linking consumer intentions to actual purchase of GM labeled food products.

    2013-01-01

    With a mandatory labeling scheme for GM food in Europe since 2004 measuring actual consumer choice in practice has become possible. Anticipating Europeans negative attitude toward GM food, the labeling was enforced to allow consumers to make an informed choice. We studied consumers actual purchase behavior of GM food products and compared this with their attitude and behavioral intention for buying GM food. We found that despite a majority of consumers voicing a negative attitude toward GM food over 50% of our European respondents stated that they did not actively avoid the purchase of GM food and 6% actually purchased one of the few available GM labeled food products in the period between September 2006 and October 2007. Our results imply that a voiced negative attitude of consumers in responses to questionnaires about their intentions is not a reliable guide for what they actually do in supermarkets. We conclude that the assumption of a negative attitude with regard to GM food is at least in part construed.

    Introduction With the increased interest and awareness toward environmental issues among Swedish consumers, their demands on what constitutes value in advertisements have also changed. Advertising-in-general is often regarded as a rather unwelcomed intrusion and a source of irritation by consumers and a common reason is that many advertisers have overdramatized or even spread false claims about products, causing great skepticism among consumers. With the increase of environmentally minded con...

    High throughput approaches such as whole genome sequencing (WGS) and whole exome sequencing (WES) create an unprecedented amount of data providing powerful resources for clinical care and research. Recently, WGS and WES services have been made available by commercial direct-to-consumer (DTC) companies. The DTC offer of genetic testing (GT) has already brought attention to potentially problematic issues such as the adequacy of consumers' informed consent and transparency of companies' research activities. In this study, we analysed the websites of four DTC GT companies offering WGS and/or WES with regard to their policies governing storage and future use of consumers' data and samples. The results are discussed in relation to recommendations and guiding principles such as the "Statement of the European Society of Human Genetics on DTC GT for health-related purposes" (2010) and the "Framework for responsible sharing of genomic and health-related data" (Global Alliance for Genomics and Health, 2014). The analysis reveals that some companies may store and use consumers' samples or sequencing data for unspecified research and share the data with third parties. Moreover, the companies do not provide sufficient or clear information to consumers about this, which can undermine the validity of the consent process. Furthermore, while all companies state that they provide privacy safeguards for data and mention the limitations of these, information about the possibility of re-identification is lacking. Finally, although the companies that may conduct research do include information regarding proprietary claims and commercialisation of the results, it is not clear whether consumers are aware of the consequences of these policies. These results indicate that DTC GT companies still need to improve the transparency regarding handling of consumers' samples and data, including having an explicit and clear consent process for research activities.

    This first edition of the Atlas provides, in reference form, a central source of information to consumers on key contacts concerned with energy in the US. Energy consumers need information appropriate to local climates and characteristics - best provided by state and local governments. The Department of Energy recognizes the authority of state and local governments to manage energy programs on their own. Therefore, emphasis has been given to government organizations on both the national and state level that influence, formulate, or administer policies affecting energy production, distribution, and use, or that provide information of interest to consumers and non-specialists. In addition, hundreds of non-government energy-related membership organizations, industry trade associations, and energy publications are included.

    Collaboration between researchers who have lived experience of mental illness and services (consumer researchers) and mental health researchers without (other mental health researchers) is an emergent development in research. Inclusion of consumer perspectives is crucial to ensuring the ethics, relevancy and validity of mental health research; yet widespread and embedded consumer collaboration of this nature is known to be impeded by attitudinal and organisational factors. Limited research describes consumer researchers' experiences of barriers. Other mental health researchers are key players in the co-production process yet there is also a paucity of research reporting their views on barriers to collaborating with consumers. To explore other researchers' views and experiences on partnering with consumer mental health researchers in Australia and New Zealand. Exploratory qualitative design. Eleven semi-structured interviews were conducted with mental health researchers. Interviews were recorded, transcribed and thematically analysed. Four themes concerning barriers to collaborating with consumers (hierarchies, status quo, not understanding, paternalism), and one theme on addressing the barriers (constantly chipping away) were identified. It is suggested that multifaceted strategies for advancing collaboration with consumers are most effective. It is imperative to attend to several barriers simultaneously to redress the inherent power disparity.

    Full Text Available Indonesia is a large market for consumer products targeting youth consumers, with populations of more than 70 million young inhabitants and market size of USD 155 billion. The large size of this potential market attracts foreign products with globallyrecognized brands to enter the Indonesian market. The objective of this study is to explain the purchase intention of youth consumers toward a particular brand of soft drink with global penetration by their perceptions and ethnocentrism. This study obtained response from 156 youths in Greater Jakarta, Indonesia. The resulting data was analyzed using structural equation modeling with LISREL software package. The study found that consumer ethnocentrism decreases purchase intention, both directly and indirectly through brand image. Contrary to the hypothesis, consumer ethnocentrism does not influence corporate image of the global firm, which significantly influences brand image but only slightly impacts purchase intentions directly.

    ABSTRACT In Pakistan majority of the consumers do not have information about genetically modified (GM) foods. In developing countries particularly in Pakistan few studies have focused on consumers' acceptability about GM foods. Using comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan, this study analyzes the determinants of consumers' acceptability of GM foods. The data was analyzed by employing the bivariate probit model and censored least absolute deviation (CLAD) models. The empirical results indicated that urban consumers are more aware of GM foods compared to rural consumers. The acceptance of GM foods was more among females' consumers as compared to male consumers. In addition, the older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods. The acceptability of the GM foods also reduces the risks among Pakistani consumers. PMID:27494790

    Consumer Medicine Information (CMI) is a brand-specific and standardized source of written medicine information available in Australia for all prescription medicines. Side-effect information is poorly presented in CMI and may not adequately address consumer information needs. To explore consumer opinions on (i) the presentation of side-effect information in existing Australian CMI leaflets and alternative study-designed CMIs and (ii) side-effect risk information and its impact on treatment decision making. Fuzzy trace, affect heuristic, frequency hypothesis and cognitive-experiential theories were applied when revising existing CMI side-effects sections. Together with good information design, functional linguistics and medicine information expertise, alternative ramipril and clopidogrel CMI versions were proposed. Focus groups were then conducted to address the study objectives. Three focus groups (n = 18) were conducted in Sydney, Australia. Mean consumer age was 58 years (range 50-65 years), with equal number of males and females. All consumers preferred the alternative CMIs developed as part of the study, with unequivocal preference for the side-effects presented in a simple tabular format, as it allowed quick and easy access to information. Consumer misunderstandings reflected literacy and numeracy issues inherent in consumer risk appraisal. Many preferred no numerical information and a large proportion preferred natural frequencies. One single method of risk presentation in CMI is unable to cater for all consumers. Consumer misunderstandings are indicative of possible health literacy and numeracy factors that influence consumer risk appraisal, which should be explored further. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Consumer attitudes toward food irradiation were evaluated. The influence of educational efforts on consumer concern for the safety of irradiated products and willingness to buy irradiated foods were measured. Demographic and psychological factors were studied in relation to attitudes. An educational leaflet describing current scientific information regarding the safety, advantages, and disadvantages of food irradiation was developed and used in two studies evaluating attitude change. In the first study, attitude change among two groups of consumers with different philosophic orientations was measured. In a second study, the effectiveness of an educational leaflet received through the mail and a poster display were examined. In a third study response to food irradiation was related to value hierarchy, locus of control, innovativeness, and demographic parameters. Initially, subjects showed a higher concern for other areas of food safety, particularly the use of chemicals and sprays on food, than toward food irradiation. After educational efforts, conventional consumers expressed minor concern toward irradiation whereas ecologically sensitive alternative consumers obtained from a food cooperative expressed major concern. A knowledgeable discussion leader lowered irradiation concern among conventional consumers. In contrast, concern among alternative consumers did not diminish when given the opportunity to discuss safety issues with a knowledgeable person

    This research paper was designed to examine the influence of corporate social responsibility (CSR) associations and environmental concerns on consumer-retailer love and attitude toward the retailer, as well as the subsequent effects on consumer behavioral intentions regarding the retailer, such as repeat patronage intention and willingness to pay a premium price for products offered by the retailer. In this study, a questionnaire survey was conducted on consumers for the purpose of investigating five proposed hypotheses. This research applied partial least squares (PLS) to exam the hypotheses and analyze the data. The findings of this research indicated that CSR association and environmental concern both have positive effects on consumer-retailer love and attitude toward the retailer. Also, the results showed that consumer-retailer love has a significantly positive effect on consumer attitude towards the retailer. This paper establishes that consumer-retailer love and attitude toward a retailer are main mediators of the relationship between CSR associations, environmental concern, and consumer behavioral intentions.

  18. Behavioral Targeting—Consumer Tracking

    2011-12-01

    Behavioral targeting is an online marketing method that collects data on the browsing activities of consumers, in order to `target' more relevant online advertising. Behavioral targeting enables marketers to reach in-market consumers and increases the value of publisher inventory. At the heart of behavioral targeting is a learning-based investigation of consumer behaviors. It helps marketers understand consumers' purchase patterns over time, mapping out a customer's activities based not only on a single purchase but also on an annual or even lifetime basis. As marketers increasingly appreciate the importance of customer lifetime value, behavioral targeting can be a foundation for creating a continuous analytical study of consumer trends and patterns. But as behavioural-targeting systems become more sophisticated and invasive, it is vital that the companies behind them are open with users about what is going on, and give them control over their personal information. The aim of this paper is to explore the various tools and techniques of behavioral targeting and its benefits to online marketing. A multiple—case study approach was used for exploring the effectiveness and acceptance of online marketing in the area of the online marketing.

    This article provides an overview of the protection that energy consumers are entitled to in the framework of the energy law. First we provide an overview of the parties operating in the energy market that consumers deal with directly or indirectly. Next the supply permit is addressed, which provides an important safeguard for consumers against unreliable suppliers. In part 4 we address the protection of the consumer prior to and while closing an agreement. Part 5 addresses the supplier's obligations. Part 6 discusses the judicial processes that are available to the consumer in case of (partial) non-observance of the agreement. We also pay attention to the compensation schemes and emergency supply in case a supplier is permanently unable to fulfill his obligations. Finally, we address the termination of the agreement. [nl

    2013-07-01

    The rise of direct-to-consumer advertising (DTCA) has mirrored, if not facilitated, the shift toward more active health care consumers. We used content analysis to identify models of physician-patient interaction in DTCA from the 1997 to 2006 issues of a broad sample of women's, men's, and common readership magazines. We also conducted 36 in-depth interviews to examine the ways consumers receive and regard advertising messages, and to explore their preferences for clinical communication and decision making. We identified four models of physician-patient relationships that vary in their locus of control (physician, patient, or shared) and the form of support sought or obtained in the relationship (emotional or instrumental). Whereas consumer interviews reflected references to all four models of interaction, only two appeared in DTCA. The limited range of interactions seen in these advertisements creates a lack of congruity between interaction styles found in advertisements vs. styles reported by actual consumers.

    Full Text Available The actuality of the topic, its extent and importance, were strong arguments for writing this paper - Problems of consumer protection in tourism. To this, also the convergence of the fields that focus on the description of a image in deep of the topic is added, we are talking about economic, legal social features or features that belong to the specifics of tourism and of products and services consumed within it. The multiple dimensions of the approached topic transform it into an exciting topic which proves its usefulness when it is known since each individual can acquire the quality of a consumer, and his rights as a consumer are nothing else but the human rights of which every individual has to be aware. A process of education and information of the citizens regarding the rights they possess as consumers could reduce a part of the problems appearing in the process of consume of tourism products and services but it would contribute to the optimization of the protection of rights and interests of the consumers. In economic terms, democracy also implies ensuring the rights of the consumers and thus their protection, therefore the concept of protection of rights and interests of consumers exists.

  5. The economics of direct-to-consumer advertising of prescription-only drugs: prescribed to improve consumer welfare?

    Science.gov (United States)

    Morgan, Steven; Mintzes, Barbara; Barer, Morris

    2003-10-01

    According to economic theory, one might expect that the informational content of direct-to-consumer advertising of prescription-only drugs would improve consumers' welfare. However, contrasting the models of consumer and market behaviour underlying this theory with the realities of the prescription-only drug market reveals that this market is distinct in ways that render it unlikely that advertising will serve an unbiased and strictly informative function. A review of qualitative evidence regarding the informational content of drug advertising supports this conclusion. Direct-to-consumer prescription drug advertising concentrates on particular products, and features of those products, to the exclusion of others, and the information provided has frequently been found to be biased or misleading in regulatory and academic evaluations. Governments that have so far resisted direct-to-consumer advertising should invest in independent sources of evidence that could help consumers and professionals to better understand the risks and benefits of treating disease with alternative drug and non-drug therapies, rather than permitting direct-to-consumer prescription drug advertising.

    2012-11-01

    Preference formation developed during the consumers evaluation of alternatives is one of the most important stages in models of consumer purchasing behaviour. This is especially true for the purchase of vegetables. The purpose of this paper is to analyze the role of extrinsic versus intrinsic attributes in the behaviour of consumer when purchasing cucumbers, considering four attributes; price, country of origin and production method (extrinsic), and freshness (intrinsic). Utilizing a sample of German tourists visiting the city of Almeria (Spain), conjoint analysis methodology is used. The results suggest that an intrinsic aspect (freshness) is the most important attribute for consumers. Therefore, marketers are advised to consider the importance of this attribute to the consumer and try to position the product in the destination markets on the basis of product freshness.

    Full Text Available The aim of this study is to prove that profile of organic food consumers is dependent on their socio-demographic characteristics as well as to shape universal organic food consumer profile. The survey included 398 consumers in Serbia. Results indicate existence of typical consumer's profile. The findings could be generalized proving that socio-demographic profiles in a larger population are strictly related to the decision to utilize organic food. The study finally contributes to the stakeholders in general, since the knowledge of the attributes can help all of them to play more active role in this supply chain. It should stimulate the personalized approach to the particular groups of consumers based on socio-demographic characteristics in order to intensify consumption of organic food and to create different marketing plans dependent on the particular countries or areas.

    Quinn, Chris; Happell, Brenda

    2015-04-01

    The management of consumer-related risk is paramount in a secure forensic mental health facility. However, the consequent risk aversion presents a major barrier to consumers forming sexual relationships in a manner that is open and accepted. Investigation of the views of nurses working in forensic mental health settings on this topic is limited, and even more so for consumers of services. This qualitative exploratory study was undertaken to elicit the views of consumers and nurses about forming sexual relationships within this long-term and secure setting. Individual in-depth interviews were conducted with 12 nurses and 10 consumers. The benefits of, and barriers to, sexual relationships was identified as a major theme, and these findings are the focus of this paper. Nurse responses included the subthemes 'supportive factors' and 'potential dangers', reflecting their qualified support. Consumer responses included the subthemes 'therapeutic', 'feeling normal', 'restrictions and barriers', and 'lack of support and secrecy'. The importance of sexual relationships was clearly articulated, as was the difficulties in forming and maintaining them within the forensic setting. More open discussion about this commonly-avoided issue and the education of nurses and other health professionals is required. © 2014 Australian College of Mental Health Nurses Inc.

    In June 2016, Korea permitted direct-to-consumer genetic testing (DTC-GT) on 42 genes. However, both the market and industry have not yet been fully activated. Considering the aforementioned context, this study provides important insights. The Korean DTC-GT policy assessment is based on consumer preference analysis using a discrete choice experiment. In August 2016, a web-based survey was conducted to collect data from 1,200 respondents. The estimation results show that consumers prefer a DTC-GT product that is cheap, tests various items or genes, offers accurate test results, and guarantees the confidentiality of all information. However, consumers are not entirely satisfied by current DTC-GT products due to the existence of insufficient and/or inadequate policies. First, the permitted testing of 42 genes is insufficient to satisfy consumers' curiosity regarding their genes. Second, the accuracy of the DTC-GT products has not been fully verified, assessed, and communicated to consumers. Finally, regulatory loopholes that allow information leaks in the DTC-GT process can occur. These findings imply that DTC-GT requires an improvement in government policy-making criteria and the implementation of practical measures to guarantee test accuracy and genetic information. © 2017 S.

  14. Under consumers' scrutiny - an investigation into consumers' attitudes and concerns about nudging in the realm of health behavior.

    2015-04-09

    Nudging strategies have recently attracted attention from scholars and policy makers for their potential in influencing people's behaviors on large scales. But is the fact that nudges do not forbid any choice-options or significantly alter people's economic incentives sufficient to conclude that nudges should be implemented? While this is discussed amongst scholars from various disciplines the voices of consumers, the target-group of nudges, remain unheard. Since understanding their knowledge about nudging and their opinions on being nudged are crucial for the evaluation of the moral appropriateness of nudging, the current study examines consumers' knowledge of and attitudes toward nudging in general and the realm of health behavior. In this qualitative investigation in-depth semi-structured interviews with UK consumers were conducted to examine consumers' attitudes to four domains of inquiry around which the scholarly discussions about nudging have revolved: consumers' approval of nudging, consumers' views on the origin of nudges, consumers' perceived effectiveness of nudging, and consumers' concerns about manipulative aspects of nudging. Interviews revealed that consumers are largely unfamiliar with the concept of nudging altogether. Once defined and explained to them most consumers approve of the concept, especially in the realm of health behavior, given particular conditions: 1. Nudges should be designed for benefiting individuals and society; 2. consumers comprehend the decision-making context and the reasoning behind the promotion of the targeted behavior. Interviews revealed very limited concerns with manipulative aspects of nudges. These findings call for better information-management to ensure consumers knowledge of nudges and awareness of their current implementation. Under that condition the findings encourage the implementation of nudges benefitting individuals and society in domains that consumers comprehend, such as health behaviors. Further research

    Food-web dynamics arise from predator-prey, parasite-host, and herbivore-plant interactions. Models for such interactions include up to three consumer activity states (questing, attacking, consuming) and up to four resource response states (susceptible, exposed, ingested, resistant). Articulating these states into a general model allows for dissecting, comparing, and deriving consumer-resource models. We specify this general model for 11 generic consumer strategies that group mathematically into predators, parasites, and micropredators and then derive conditions for consumer success, including a universal saturating functional response. We further show how to use this framework to create simple models with a common mathematical lineage and transparent assumptions. Underlying assumptions, missing elements, and composite parameters are revealed when classic consumer-resource models are derived from the general model.

    Full Text Available It is widely accepted that only informed consumers are protected from potential violation of their consumer rights. Advertising represents one of the main ways of informing consumers, so it is of crutial importance for it to include adequate information that can facilitate decision making proces regarding the purchase. With aim of preventing violation of basic consumer rights, advertising is regulated by legislation, both on EU level and on national level in Republic of Serbia, and while so special attention is dedicated to defining advertising that can possibly lead to deception of consumers. Authors of this paper are focused on analysing legislation and theoretical explanations of deceptive advertising. Results of the research regarding advertising in Serbia and ability of consumers to protect themselves from deceptive advertising are presented. The main aim of the authors is to contribute to increasing level of consumers' self-protection through increasing level of their counciousness on deceptive advertising and its concequences.

    2008-08-01

    Although consumer-directed health care has become a fashionable concept in recent years, stories abound asking whether the so-called free market in health care can provide adequate access to quality health care at an affordable price. In spite of these concerns, consumer-directed health care continues as the face of legitimacy behind an industry-driven campaign to limit regulatory protections of the consumer in the market and encourage the growth of health insurance products that place spending options closer to the consumer, whether or not these options are available, affordable, or easily understood. Understanding whether this empowerment is real begins with first asking what it now means to be a health consumer. This commentary offers perspective on the dilemma faced by millions of Americans in navigating our health care system under the assumption that market-driven choices foster consumer empowerment in health care, and suggests approaches for expanding the true consumer voice.

    2014-06-01

    Research purpose: The purpose of this study is to explore the principles underlying transformative consumer research, including how it differs from traditional research methods and pointing out some established research areas in this field. Motivation for the study: Apart from pointing to a lack of literature, this article highlights the relevance of this approach for emerging countries by investigating the principles and practices embedded in transformative consumer research. It provides some indication of how an investigation of these areas may contribute to enhancing the relevance of consumer research to its various stakeholders. Research design, approach and method: The author used a literature review to conduct the study. Main findings: It appears that consumer research currently lacks external and internal relevance. A transformative consumer-research approach may address some of the fundamental problems in the way consumer psychologists plan and conduct their research, contributing to this lack of relevance. Practical/managerial implications: Most stages of the traditional research approach may need to be adapted for transformative research purposes. Some approaches appear particularly suited to transformative consumer research, including revelatory, incendiary, policy, participatory and coalition research. Contribution/value-add: This study’s primary contribution stems from suggesting a rather novel additional approach to enhance the relevance of consumer research in South Africa, pointing out some established practices in the field of transformative consumer research and suggesting how they may augment consumer research in South Africa.

    Directory of Open Access Journals (Sweden)

    R van Niekerk

    2010-12-01

    Full Text Available South Africa was in need of a comprehensive framework of legislation, policies and government authorities to regulate consumer-supplier interaction. The Consumer Protection Act 68 of 2008, which was signed by the President of the Republic of South Africa on 29 April 2009 and published in the Government Gazette on 29 April 2009, now provides an extensive framework for consumer protection and aims to develop, enhance and protect the rights of consumers and to eliminate unethical suppliers and improper business practices. Certain areas of the common law regarding consumer rights have been codified by the Act and certain unfair business practices that were previously unregulated are now governed by the Act. The Act has a wide field of application. It applies to every transaction occurring within South Africa for the supply of goods or services or the promotion of goods or services and the goods or services themselves, unless the transaction is exempted from the application of the Act. The Act also specifically regulates aspects of franchise agreements. In terms of the Act, consumers obtain several new rights and some existing rights are broadened and reinforced. These rights are: the right to equality in the consumer market; privacy; choice; disclosure and information; fair and responsible marketing; fair and honest dealing; fair, just and reasonable terms and conditions; and fair value, good quality and safety. The last right in terms of the Act deals with a supplier's accountability to consumers. The authors critically analyse and discuss these rights. It is clear that the Act is written in favour of the consumer.

    2013-10-14

    Little is known about how consumers of direct-to-consumer personal genetic services share personal genetic risk information. In an age of ubiquitous online networking and rapid development of social networking tools, understanding how consumers share personal genetic risk assessments is critical in the development of appropriate and effective policies. This exploratory study investigates how consumers share personal genetic information and attitudes towards social networking behaviors. Adult participants aged 23 to 72 years old who purchased direct-to-consumer genetic testing from a personal genomics company were administered a web-based survey regarding their sharing activities and social networking behaviors related to their personal genetic test results. 80 participants completed the survey; of those, 45% shared results on Facebook and 50.9% reported meeting or reconnecting with more than 10 other individuals through the sharing of their personal genetic information. For help interpreting test results, 70.4% turned to Internet websites and online sources, compared to 22.7% who consulted their healthcare providers. Amongst participants, 51.8% reported that they believe the privacy of their personal genetic information would be breached in the future. Consumers actively utilize online social networking tools to help them share and interpret their personal genetic information. These findings suggest a need for careful consideration of policy recommendations in light of the current ambiguity of regulation and oversight of consumer initiated sharing activities.

  9. Forgiveness from Emotion Fit: Emotional Frame, Consumer Emotion, and Feeling-Right in Consumer Decision to Forgive.

    Science.gov (United States)

    Ran, Yaxuan; Wei, Haiying; Li, Qing

    2016-01-01

    Three studies examine an emotion fit effect in the crisis communication, namely, the interaction between emotional frames of guilt and shame and consumer emotions of anger and fear on consumer forgiveness. Guilt-framing communication results in higher forgiveness than shame-framing for angry consumers, whereas shame-framing communication results in higher forgiveness than guilt-framing for fearful consumers. These effects are driven by consumers' accessible regulatory foci associated with anger/fear and guilt/shame. Specifically, feelings of anger activate a promotion focus that is represented by guilt frames, while feelings of fear activate a prevention focus that is enacted by shame frames. Compared with emotion non-fit (i.e., anger to shame and fear to guilt), emotion fit (i.e., anger to guilt and fear to shame) facilitates greater feeling-right and consumer forgiveness. The findings offer novel insights for extant literature on emotion, crisis communication, and regulatory focus theory, as well as practical suggestions regarding the emotional frames.

    Full Text Available The European Single Market is an ongoing project that will continue to further develop and adapt to changing realities. Traditional economic activities, and the administrative rules governing them, face the challenge of adapting to developments that blur the dividing lines, for example, between shop and online sales or between traditional media and Internet communication. Convergence of this type will lead to a European Digital Single Market. A genuine Digital Single Market would generate new types of growth and also sustainable economic and social benefits for all European citizens. There are still a number of barriers which impose obstacles for the development of the digital market in Europe. Obstacles which can be identified include national differences regarding data protection rules, e-commerce rules, consumer protection rules and other legislation pertaining to information flows. The paper brings in discussion the advantages of a Digital Single Market, the obstacles in developing it in connection with e-commerce regulations, consumer protection and information flows legislation and also the premises for implementing a Digital Single Market. Consumers’ trust in on-line commerce results as one of the driving factors in implementing a Digital Single Market. These are some of the main obstacles for the boosting consumers’ confidence in the European Single Market. Improving consumer confidence in cross-border shopping online by taking appropriate policy action could provide a major boost to economic growth in Europe. Empowered and confident consumers can drive forward the European economy. Starting from the results of the Flash Euro-barometer survey „Consumer attitudes towards cross-border trade and consumer protection this study analyzes consumer`s readiness for the European Digital Single Market

    The identification of consumer innovators offers marketing managers the opportunity to tailor new products to the buyers who initiate the diffusion of innovations. Progress has been made in identifying such consumers in economic and social terms, but there are advantages of cost and convenience in isolating the personality profiles of innovators, especially during prelaunch product testing. But innovative consumers' distinctive personality traits have proved elusive. This paper reports an inv...

  13. Labelling schemes: From a consumer perspective

    Labelling of food products attracts a lot of political attention these days. As a result of a number of food scandals, most European countries have acknowledged the need for more information and better protection of consumers. Labelling schemes are one way of informing and guiding consumers....... However, initiatives in relation to labelling schemes seldom take their point of departure in consumers' needs and expectations; and in many cases, the schemes are defined by the institutions guaranteeing the label. It is therefore interesting to study how consumers actually value labelling schemes....... A recent MAPP study has investigated the value consumers attach the Government-controlled labels 'Ø-mærket' and 'Den Blå Lup' and the private supermarket label 'Mesterhakket' when they purchase minced meat. The results reveal four consumer segments that use labelling schemes for food products very...

  14. The Political Theology of Consumer Sovereignty

    Schwarzkopf, Stefan

    2011-01-01

    The article analyses the common notion that the consumer society is a reflection of those principles in the market that also provide the ideas of democracy and liberal constitutionalism with legitimacy in the political realm. The inalienable right to self-development and self-determination makes...... the individual the starting and ending point of life, rendering all spheres of market and society a ‘republic of choice’. But if consumer society shares the essentials of liberal constitutionalism and the rational, processual nature of democratic representation, then its ontology needs to be investigated...... to understanding the ontology of consumer society. But rather than simply placing sovereignty into the hands of the independent, self-determined consumer, the earliest ontologists of the consumer society took recourse to medieval political theology and presented the consumer market as a new corpus mysticum.

    Full Text Available A paradigm influences what we see and conceive about certain facts. Paradigm can also influence what we accept as a truth. Yet, the debate over which paradigm and methodology is best suit for marketing and consumer behavior has begun since 1980s. Many researchers criticized the domination of logical empiricism paradigm and offered alternative paradigm to understand marketing and consumer behavior. This article discusses several paradigms and methodology, which are part of qualitative paradigm, and compares them with positivism paradigm. This article will also point to the importance of reconciliation between qualitative and quantitative paradigm in order to improve marketing and consumer behavior studies.

    Full Text Available The articol presents a category of consumption models which shows the manner how theexpenses of consume in an economy are related to the available income achieved by this economy and theinterest rate from the financial market. Since the income as well as the expenses of consume are realizedin time, such dynamic models of consume are also referred to as models of inter-temporal consume,emphasizing therefore the fact that the available income achieved at a certain moment may be used forconsume at a future moment, whereas the decision of consume taken at a current moment may consider theincome that is to be achieved in the future.

    Full Text Available Little is known about how consumers of direct-to-consumer personal genetic services share personal genetic risk information. In an age of ubiquitous online networking and rapid development of social networking tools, understanding how consumers share personal genetic risk assessments is critical in the development of appropriate and effective policies. This exploratory study investigates how consumers share personal genetic information and attitudes towards social networking behaviors. Methods: Adult participants aged 23 to 72 years old who purchased direct-to-consumer genetic testing from a personal genomics company were administered a web-based survey regarding their sharing activities and social networking behaviors related to their personal genetic test results. Results: 80 participants completed the survey; of those, 45% shared results on Facebook and 50.9% reported meeting or reconnecting with more than 10 other individuals through the sharing of their personal genetic information. For help interpreting test results, 70.4% turned to Internet websites and online sources, compared to 22.7% who consulted their healthcare providers. Amongst participants, 51.8% reported that they believe the privacy of their personal genetic information would be breached in the future. Conclusion: Consumers actively utilize online social networking tools to help them share and interpret their personal genetic information. These findings suggest a need for careful consideration of policy recommendations in light of the current ambiguity of regulation and oversight of consumer initiated sharing activities.

    Although the first experiments on food irradiation were carried out in 1916 in Sweden, food irradiation, is for consumers, a relatively new technology. From the sixties food irradiation has been applied more and more, so that the consumer movement has become alert to this technology. Since then a lot of controversies have arisen in the literature about wholesomeness, safety, effects, etc. Food irradiation is currently permitted on a small scale in about 30 countries; in some countries or states food irradiation has been put under a ban (e.g. Australia, New Zealand, New Jersey). The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) have, however, chosen food irradiation as a safe and sound method for preserving and improving the safety of food. Reactions on the part of the consumer organizations of many countries are however not in favour of or are even opposed to food irradiation. In this chapter consumer acceptance related to technological developments is described, then the convergence of the consumer movement on public opinion and concern on food irradiation is discussed. The need for labelling of irradiated food products is discussed and finally recommendations are given of ways to change consumers attitudes to food irradiation. (author)

  7. Consumers' various and surprising responses to direct-to-consumer advertisements in magazine print.

    Science.gov (United States)

    Arney, Jennifer; Street, Richard L; Naik, Aanand D

    2013-01-01

    Direct-to-consumer advertising (DTCA) is ubiquitous in media outlets, but little is known about the ways in which consumers' values, needs, beliefs, and biases influence the perceived meaning and value of DTCA. This article aims to identify the taxonomy of readership categories that reflect the complexity of how health care consumers interact with DTCA, with particular focus on individuals' perceptions of print DTCA in popular magazines. Respondent-driven sampling was used to recruit 18 male and female magazine readers and 18 male and female prescription medication users aged 18-71 years. Semi-structured, in-depth interviews with consumers about their attentiveness, motivations, perceived value, and behavioral responses to DTCA were conducted. The analyses were guided by principles of grounded theory analysis; four categories that vary in consumers' attentiveness, motivations, perceived value, and behavioral responses to DTCA were identified. Two categories - the lay physician and the informed shopper - see value in information from DTCA and are likely to seek medical care based on the information. One category - the voyeur - reads DTCA, but is not likely to approach a clinician regarding advertised information. The fourth category - the evader - ignores DTCA and is not likely to approach a clinician with DTCA information. Responses to DTCA vary considerably among consumers, and physicians should view patients' understanding and response to DTCA within the context of their health-related needs. Patients' comments related to DTCA may be used as an opportunity to engage and understand patients' perspectives about illness and medication use. Clinicians may use information about these categories to facilitate shared understanding and improve communication within the doctor-patient relationship.

  12. Consumer Legislation and E-Commerce Challenges

    Directory of Open Access Journals (Sweden)

    Jason Freeman

    2015-07-01

    Full Text Available Where there is vigorous competition, and consumer confidence, there is economic growth. E-commerce drives both of these but there remain situations where traders exploit technology or consumer behavioural biases, and seek to compete on the wrong things –such as unrealistic up front prices. This harms competition and can reduce consumer trust, meaning that consumers consume less. This could occur when traders: i prevent consumers from accessing, assessing or acting on information, and so make the wrong choice; ii take advantage of their superior understanding of technology to collect data or money from consumers; iii abuse the advantages of the internet (ease of set up, cross jurisdictional reach, access to markets to misrepresent the price, the quality, the range of products on offer, or the service you will get.Firms should therefore behave responsibly, and not seek to steal an unfair march on their competitors. Effective enforcement incentivises the right behaviours. In order to enforce effectively, EU agencies need to prioritise robustly and build strong competence in internet investigation. Increasingly enforcement activities need to be run as international projects involving non EU enforcers and industry allies –and we need to be willing to protect overseas consumers as well as our own. It is important that the legal framework facilitates, rather than hinders, enforcement –so that for example investigators can easily discover the true identity of traders who run anonymous websites, that they are able to carry out covert test purchases, and so that websites causing harm to the economic interests of consumers can swiftly be removed.There are a number of areas where the EU legislator should consider further work, in order to address those persistent threats that have proven difficult to eradicate so far: clarifying the scope of platform responsibility; extending consumer protection to all individuals; ensuring all CPC enforcers have

Regulators of polarity have been extensively studied, and the critical importance of the Par (partitioning-defective) complex as the polarity machinery is now recognized in a wide range of eukaryotic systems. The Par polarity module is evolutionarily conserved, but its mechanism and cooperating factors vary among different systems. Here we describe the cloning and characterization of a pond snail Lymnaea stagnalis homologue of partitioning-defective 6 (Lspar6). The protein product LsPar6 shows high affinity for microtubules and localizes to the mitotic apparatus during embryonic cell division. In vitro assays revealed direct binding of LsPar6 to tubulin and microtubules, which is the first evidence of the direct interaction between the two proteins. The interaction is mediated by two distinct regions of LsPar6 both located in the N-terminal half. Atypical PKC, a functional partner of Par6, was also found to localize to the mitotic spindle. These results suggest that the L. stagnalis Par complex employs the microtubule network in cell polarity processes during the early embryogenesis. Identical sequence and localization of LsPar6 for the dextral and the sinistral snails exclude the possibility of the gene being the primary determinant of handedness.

    2010-07-01

    Digital photographs of pork chops varying systematically in appearance were presented to 716 Taiwanese consumers in a study that aimed to identify the most important characteristics of fresh pork which determine consumer choice in Taiwan. Relationships between consumer segmentation in choice and socio-demographic and cultural differences were also investigated. Colour and fat cover were the most frequently chosen of the four characteristics studied. Dark red colour was preferred by 64% of consumers and lean fat cover by 44%. Marbling and drip were less important in the decision making process being used by less than a half of consumers. The four preference-based clusters of consumers showed no correlation with socio-demographic-based consumer clusters, but did show significant links with possession of a refrigerator, age at which schooling was completed, liking pork for its price and gender of consumer.

    To ensure the provision of patient-centred health care, it is essential that consumers are actively involved in the process of determining and implementing health-care quality improvements. However, common strategies used to involve consumers in quality improvements, such as consumer membership on committees and collection of patient feedback via surveys, are ineffective and have a number of limitations, including: limited representativeness; tokenism; a lack of reliable and valid patient feedback data; infrequent assessment of patient feedback; delays in acquiring feedback; and how collected feedback is used to drive health-care improvements. We propose a new active model of consumer engagement that aims to overcome these limitations. This model involves the following: (i) the development of a new measure of consumer perceptions; (ii) low cost and frequent electronic data collection of patient views of quality improvements; (iii) efficient feedback to the health-care decision makers; and (iv) active involvement of consumers that fosters power to influence health system changes. © 2018 The Authors Health Expectations published by John Wiley & Sons Ltd.

    Simple Summary The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Pet owners evaluated dry dog food samples available in the US market. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Abstract The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Eight dry dog food samples available in the US market were evaluated by pet owners. In this study, consumers evaluated overall liking, aroma, and appearance liking of the products. Consumers were also asked to predict their purchase intent, their dog’s liking, and cost of the samples. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Overall liking clusters were not related to income, age, gender, or education, indicating that general consumer demographics do not appear to play a main role in individual consumer acceptance of dog food products.

    Full Text Available The main objective of this study was to understand the concerns and problems faced by older people in an industrializing middle-income country, Malaysia, in their process of acquiring products to meet their everyday needs. Respondents aged 55 and over were interviewed in eight states throughout Peninsular Malaysia providing 1356 usable questionnaires; two-thirds from urban and one-third from rural areas. Education, health status, and life satisfaction were recorded. Service patronage behaviour was examined for four main categories of commonly-sought consumer goods: groceries, health supplements, apparel, eating outlets, plus selected services (public transport, vacation packages and financial services. The findings showed that older adults in Malaysia are rather discerning consumers. Many respondents are price conscious and have developed consumer attitudes with regard to attitude of staff and assistance rendered. Many display a good ability to discriminate and to select, especially on the basis of price and durability of products and many appear to be acting as effectively as consumers in any other age group.

  7. Consumer experiences in a consumer-driven health plan.

    Christianson, Jon B; Parente, Stephen T; Feldman, Roger

    2004-08-01

    To assess the experience of enrollees in a consumer-driven health plan (CDHP). Survey of University of Minnesota employees regarding their 2002 health benefits. Comparison of regression-adjusted mean values for CDHP and other plan enrollees: customer service, plan paperwork, overall satisfaction, and plan switching. For CDHP enrollees only, use of plan features, willingness to recommend the plan to others, and reports of particularly negative or positive experiences. There were significant differences in experiences of CDHP enrollees versus enrollees in other plans with customer service and paperwork, but similar levels of satisfaction (on a 10-point scale) with health plans. Eight percent of CDHP enrollees left their plan after one year, compared to 5 percent of enrollees leaving other plans. A minority of CDHP enrollees used online plan features, but enrollees generally were satisfied with the amount and quality of the information provided by the CDHP. Almost half reported a particularly positive experience, compared to a quarter reporting a particularly negative experience. Thirty percent said they would recommend the plan to others, while an additional 57 percent said they would recommend it depending on the situation. Much more work is needed to determine how consumer experience varies with the number and type of plan options available, the design of the CDHP, and the length of time in the CDHP. Research also is needed on the factors that affect consumer decisions to leave CDHPs.

    Full Text Available This paper investigates consumer involvement profile among people who intend to purchase mobile devises. The study considers the effects of various factors influencing on purchase intention including consumers’ personal characteristics such as age, gender, income as well as some external factors including advertisement. The study uses a questionnaire in Likert scale, originally developed by O’Cass (2000 [O’Cass, A. (2000. An assessment of consumers' product, purchase decision, advertising and consumption involvement in fashion clothing. Journal of Economic Psychology, 21, 545-576.]. The questionnaire has been distributed among 385 people, randomly who purchased mobile devices from a mall in city of Tehran, Iran. Using Pearson correlation test, the study has concluded that oral advertisement as well as consumer purchase involvement have positive and strong relationship with consumer’s purchase intention. In terms of age, people aged 20-30 maintained the highest purchase intention. In addition, in terms of gender, men had more purchase involvement than women did.

    2014-05-01

    Full Text Available The goal of the present paper is to evaluate the status of the protection of consumer right to information before the purchase from Romanian online stores. The perspective focuses on technical consumer goods. The research pursued two major objectives. The former consisted in analysing the compliance of the online stores with the provisions of article 6 paragraph 1 of the Directive 2011/83/EU on consumer rights, relative to the information provided to potential buyers before the purchase. The latter was to identify the consumer awareness of the rights stipulated by article 6 of the directive, as well as to study the opinions of consumers relative to the information that online stores are compelled to supply before purchase. The first objective was accomplished by applying the content analysis method to the information available on the Web for a sample of 100 online stores. The second objective was achieved through the survey method on a sample of 351 persons from the 25 to 34 age group, residing in Bucharest. Compared to other studies, the major contributions of the present research approach are the following: the investigation of an extensive sample of online stores; the wider range of products; the focus on both online stores and consumers. The results show that improvements are needed in the level of compliance and in the consumer awareness of own rights.

    2017-02-01

    Full Text Available The consumer plays a key role in resource conservation; therefore, it is important to know consumer behavior to identify consumer profiles and to promote pro-environmental practices in society that encourage resource conservation and reductions in waste generation. The purpose of this paper is to implement a fuzzy model to evaluate consumer behavior in relation to three pro-environmental practices that can be implemented at the household level, including reductions in resource consumption (reduce, reuse of resources (reuse, and recycling (recycle. To identify socio-demographic profiles that characterize an environmentally responsible consumer, 2831 surveys were applied on a representative sample of consumers residing in a Mexican city. Fuzzy logic and neural networks were applied using a Sugeno-type subtractive clustering to determine each profile. The model input variables were socioeconomic status, age, education level, monthly income, occupation and the type of organizations with which the consumer is affiliated. The output variables were represented by pro-environmental practices. Results show that the consumer practices are performed independently of each other, with the most frequent pro-environmental consumer practices being reduction and reuse.

    Fernando Ormonde Teixeira

    Full Text Available Abstract This paper investigates what are the main components of consumer's inflation expectations. We combine the FGV's Consumer Survey with the indices of inflation (IPCA and government regulated prices, professional forecasts disclosed in the Focus report, and media data which we crawl from one of the biggest and most important Brazilian newspapers, Folha de São Paulo, to determine what factors are responsible for and improve consumer's forecast accuracy. We found gender, age and city of residence as major elements when analyzing micro-data. Aggregate data shows the past inflation as an important trigger in the formation of consumers' expectations and professional forecasts as negligible. Moreover, the media plays a significant role, accounting not only for the expectations' formation but for a better understanding of actual inflation as well.

  9. Bioaccumulation and toxicity of CuO nanoparticles by a freshwater invertebrate after waterborne and dietborne exposures

    2014-01-01

    The incidental ingestion of engineered nanoparticles (NPs) can be an important route of uptake for aquatic organisms. Yet, knowledge of dietary bioavailability and toxicity of NPs is scarce. Here we used isotopically modified copper oxide (65CuO) NPs to characterize the processes governing their bioaccumulation in a freshwater snail after waterborne and dietborne exposures. Lymnaea stagnalis efficiently accumulated 65Cu after aqueous and dietary exposures to 65CuO NPs. Cu assimilation efficiency and feeding rates averaged 83% and 0.61 g g–1 d–1 at low exposure concentrations (–1), and declined by nearly 50% above this concentration. We estimated that 80–90% of the bioaccumulated 65Cu concentration in L. stagnalis originated from the 65CuO NPs, suggesting that dissolution had a negligible influence on Cu uptake from the NPs under our experimental conditions. The physiological loss of 65Cu incorporated into tissues after exposures to 65CuO NPs was rapid over the first days of depuration and not detectable thereafter. As a result, large Cu body concentrations are expected in L. stagnalis after exposure to CuO NPs. To the degree that there is a link between bioaccumulation and toxicity, dietborne exposures to CuO NPs are likely to elicit adverse effects more readily than waterborne exposures.

  10. Predicting dietborne metal toxicity from metal influxes

    Science.gov (United States)

    Croteau, M.-N.; Luoma, S.N.

    2009-01-01

    Dietborne metal uptake prevails for many species in nature. However, the links between dietary metal exposure and toxicity are not well understood. Sources of uncertainty include the lack of suitable tracers to quantify exposure for metals such as copper, the difficulty to assess dietary processes such as food ingestion rate, and the complexity to link metal bioaccumulation and effects. We characterized dietborne copper, nickel, and cadmium influxes in a freshwater gastropod exposed to diatoms labeled with enriched stable metal isotopes. Metal influxes in Lymnaea stagnalis correlated linearly with dietborne metal concentrations over a range encompassing most environmental exposures. Dietary Cd and Ni uptake rate constants (kuf) were, respectively, 3.3 and 2.3 times higher than that for Cu. Detoxification rate constants (k detox) were similar among metals and appeared 100 times higher than efflux rate constants (ke). Extremely high Cu concentrations reduced feeding rates, causing the relationship between exposure and influx to deviate from linearity; i.e., Cu uptake rates leveled off between 1500 and 1800 nmol g-1 day-1. L. stagnalis rapidly takes up Cu, Cd, and Ni from food but detoxifies the accumulated metals, instead of reducing uptake or intensifying excretion. Above a threshold uptake rate, however, the detoxification capabilities of L. stagnalis are overwhelmed.

  11. Biogeochemical controls of uranium bioavailability from the dissolved phase in natural freshwaters

    Croteau, Marie-Noele; Fuller, Christopher C.; Cain, Daniel J.; Campbell, Kate M.; Aiken, George R.

    2016-01-01

    To gain insights into the risks associated with uranium (U) mining and processing, we investigated the biogeochemical controls of U bioavailability in the model freshwater speciesLymnaea stagnalis (Gastropoda). Bioavailability of dissolved U(VI) was characterized in controlled laboratory experiments over a range of water hardness, pH, and in the presence of complexing ligands in the form of dissolved natural organic matter (DOM). Results show that dissolved U is bioavailable under all the geochemical conditions tested. Uranium uptake rates follow first order kinetics over a range encompassing most environmental concentrations. Uranium uptake rates in L. stagnalis ultimately demonstrate saturation uptake kinetics when exposure concentrations exceed 100 nM, suggesting uptake via a finite number of carriers or ion channels. The lack of a relationship between U uptake rate constants and Ca uptake rates suggest that U does not exclusively use Ca membrane transporters. In general, U bioavailability decreases with increasing pH, increasing Ca and Mg concentrations, and when DOM is present. Competing ions did not affect U uptake rates. Speciation modeling that includes formation constants for U ternary complexes reveals that the aqueous concentration of dicarbonato U species (UO2(CO3)2–2) best predicts U bioavailability to L. stagnalis, challenging the free-ion activity model postulate.

    Stress alters the ability to form, recall and maintain memory according to the Yerkes-Dodson/Hebb (YDH) law. The effects of environmentally relevant stressors, such as low environmental calcium and crowding, on learning and memory have previously been described in a laboratory-reared 'average' strain of Lymnaea stagnalis (i.e. the Dutch strain) as well as two strains of freshly collected L . stagnalis with enhanced memory formation abilities (i.e. 'smart' snails). Here, we use L . stagnalis to study the effects of other environmentally relevant stressors on memory formation in two other strains of freshly collected snails, one 'smart' and one 'average'. The stressors we examined are thermal, resource restriction combined with food odour, predator detection and, for the first time, tissue injury (shell damage). We show that the same stressor has significantly different effects on memory formation depending on whether snails are 'smart' or 'average'. Specifically, our data suggest that a stressor or a combination of stressors act to enhance memory in 'average' snails but obstruct memory formation in 'smart' snails. These results are consistent with the YDH law and our hypothesis that 'smart' snails are more easily stressed than 'average' snails. © 2017. Published by The Company of Biologists Ltd.

  13. Consumer Acceptance of Dry Dog Food Variations

    Brizio Di Donfrancesco

    2014-06-01

    Full Text Available The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Eight dry dog food samples available in the US market were evaluated by pet owners. In this study, consumers evaluated overall liking, aroma, and appearance liking of the products. Consumers were also asked to predict their purchase intent, their dog’s liking, and cost of the samples. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Overall liking clusters were not related to income, age, gender, or education, indicating that general consumer demographics do not appear to play a main role in individual consumer acceptance of dog food products.

    2007-01-01

    The effect of direct-to-consumer (DTC) television advertising of prescription medications is a growing concern of the United States (U.S.) Congress, state legislatures, and the Food and Drug Administration (FDA). This research study was conducted in order to examine consumers' perceived preferences of DTC television advertisement in relation to "reminder" "help-seeking," and "product-claim" FDA-approved advertisement categories. An additional objective was to examine the influence of DTC television advertising of prescription drugs on consumers' tendency to seek more information about the medication and/or the medical condition. The research indicates that DTC television drug ads appear to be insufficient for consumers to make informed decisions. Their mixed perception and acceptance of the advertisements seem to influence them to seek more information from a variety of medical sources.

  3. A Lexical-Ontological Resource for Consumer Heathcare

    Science.gov (United States)

    Cardillo, Elena

    In Consumer Healthcare Informatics it is still difficult for laypersons to understand and act on health information, due to the persistent communication gap between specialized medical terminology and that used by healthcare consumers. Furthermore, existing clinically-oriented terminologies cannot provide sufficient support when integrated into consumer-oriented applications, so there is a need to create consumer-friendly terminologies reflecting the different ways healthcare consumers express and think about health topics. Following this direction, this work suggests a way to support the design of an ontology-based system that mitigates this gap, using knowledge engineering and Semantic Web technologies. The system is based on the development of a consumer-oriented medical terminology which will be integrated with other existing domain ontologies/terminologies into a medical ontology repository. This will support consumer-oriented healthcare systems by providing many knowledge services to help users in accessing and managing their healthcare data.

  4. Website quality indicators for consumers.

    Griffiths, Kathleen M; Christensen, Helen

    2005-11-15

    The rating tool DISCERN was designed for use by consumers without content expertise to evaluate the quality of health information. There is some evidence that DISCERN may be a valid indicator of evidence-based website quality when applied by health professionals. However, it is not known if the tool is a valid measure of evidence-based quality when used by consumers. Since it is a lengthy instrument requiring training in its use, DISCERN may prove impractical for use by the typical consumer. It is therefore important to explore the validity of other simpler potential indicators of site quality such as Google PageRank. This study aimed to determine (1) whether the instrument DISCERN is a valid indicator of evidence-based Web content quality for consumers without specific mental health training, and (2) whether Google PageRank is an indicator of website content quality as measured by an evidence-based gold standard. This was a cross-sectional survey of depression websites using consumer and health professional raters. The main outcome measures were (1) site characteristics, (2) evidence-based quality of content as measured by evidence-based depression guidelines, (3) DISCERN scores, (4) Google PageRank, and (5) user satisfaction. There was a significant association between evidence-based quality ratings and average DISCERN ratings both for consumers (r = 0.62, P = .001) and health professionals (r = 0.80, P PageRank (r = 0.59, P = .002). However, the correlation between DISCERN scores and user satisfaction was higher than the correlation between Google PageRank and user satisfaction. DISCERN has potential as an indicator of content quality when used either by experts or by consumers. Google PageRank shows some promise as an automatic indicator of quality.

    The aim was to investigate socio-demographic characteristics, and attitudes to food and health of vegetarians, non-vegetarian consumers of meat substitutes, and meat consumers in The Netherlands. The sample used for this study (participants > or =18 years) was taken from the Dutch National Food Consumption Survey, 1997/1998. Vegetarians (n = 63) and consumers of meat substitutes (n = 39) had similar socio-demographic profiles: higher education levels, higher social economic status, smaller households, and more urbanised residential areas, compared to meat consumers (n = 4313). Attitudes to food were assessed by the food-related lifestyle instrument. We found that vegetarians (n = 32) had more positive attitudes towards importance of product information, speciality shops, health, novelty, ecological products, social event, and social relationships than meat consumers (n = 1638). The health consciousness scale, which was used to assess attitudes to health, supported earlier findings that vegetarians are more occupied by health. Food-related lifestyle and health attitudes of meat substitute consumers (n = 17) were predominantly in-between those from vegetarians and meat consumers. The outcome of this study suggests that in strategies to promote meat substitutes for non-vegetarian consumers, the focus should not only be on health and ecological aspects of foods.

  8. Forgiveness from Emotion Fit: Emotional Frame, Consumer Emotion, and Feeling-Right in Consumer Decision to Forgive

    Science.gov (United States)

    Ran, Yaxuan; Wei, Haiying; Li, Qing

    2016-01-01

    Three studies examine an emotion fit effect in the crisis communication, namely, the interaction between emotional frames of guilt and shame and consumer emotions of anger and fear on consumer forgiveness. Guilt-framing communication results in higher forgiveness than shame-framing for angry consumers, whereas shame-framing communication results in higher forgiveness than guilt-framing for fearful consumers. These effects are driven by consumers’ accessible regulatory foci associated with anger/fear and guilt/shame. Specifically, feelings of anger activate a promotion focus that is represented by guilt frames, while feelings of fear activate a prevention focus that is enacted by shame frames. Compared with emotion non-fit (i.e., anger to shame and fear to guilt), emotion fit (i.e., anger to guilt and fear to shame) facilitates greater feeling-right and consumer forgiveness. The findings offer novel insights for extant literature on emotion, crisis communication, and regulatory focus theory, as well as practical suggestions regarding the emotional frames. PMID:27895612

    2007-02-01

    To determine consumer behaviour in the pharmacy waiting area. The applied methods for data-collection were direct observations. Three Dutch community pharmacies were selected for the study. The topics in the observation list were based on available services at each waiting area (brochures, books, illuminated new trailer, children's play area, etc.). Per patient each activity was registered, and at each pharmacy the behaviour was studied for 2 weeks. Most patients only waited during the waiting time at the studied pharmacies. Few consumers obtained written information during their wait. The waiting area may have latent possibilities to expand the information function of the pharmacy and combine this with other activities that distract the consumer from the wait. Transdisciplinary research, combining knowledge from pharmacy practice research with consumer research, has been a useful approach to add information on queueing behaviour of consumers.

  17. A Lexical-Ontological Resource for Consumer Healthcare

    Science.gov (United States)

    Cardillo, Elena; Serafini, Luciano; Tamilin, Andrei

    In Consumer Healthcare Informatics it is still difficult for laypeople to find, understand and act on health information, due to the persistent communication gap between specialized medical terminology and that used by healthcare consumers. Furthermore, existing clinically-oriented terminologies cannot provide sufficient support when integrated into consumer-oriented applications, so there is a need to create consumer-friendly terminologies reflecting the different ways healthcare consumers express and think about health topics. Following this direction, this work suggests a way to support the design of an ontology-based system that mitigates this gap, using knowledge engineering and semantic web technologies. The system is based on the development of a consumer-oriented medical terminology that will be integrated with other medical domain ontologies and terminologies into a medical ontology repository. This will support consumer-oriented healthcare systems, such as Personal Health Records, by providing many knowledge services to help users in accessing and managing their healthcare data.

  18. Optimal tariff design under consumer self-selection

    Energy Technology Data Exchange (ETDEWEB)

    Raesaenen, M.; Ruusunen, J.; Haemaelaeinen, R.

    1995-12-31

    This report considers the design of electricity tariffs which guides an individual consumer to select the tariff designed for his consumption pattern. In the model the utility maximizes the weighted sum of individual consumers` benefits of electricity consumption subject to the utility`s revenue requirement constraints. The consumers` free choice of tariffs is ensured with the so-called self-selection constraints. The relationship between the consumers` optimal choice of tariffs and the weights in the aggregated consumers` benefit function is analyzed. If such weights exist, they will guarantee both the consumers` optimal choice of tariffs and the efficient consumption patterns. Also the welfare effects are analyzed by using demand parameters estimated from a Finnish dynamic pricing experiment. The results indicate that it is possible to design an efficient tariff menu with the welfare losses caused by the self-selection constraints being small compared with the costs created when some consumers choose tariffs other than assigned for them.

    2004-01-01

    This paper examines the impact of changes in the medical marketplace on medicalization in U.S. society. Using four cases (Viagra, Paxil, human growth hormone and in vitro fertilization), we focus on two aspects of the changing medical marketplace: the role of direct-to-consumer advertising of prescription drugs and the emergence of private medical markets. We demonstrate how consumers and pharmaceutical corporations contribute to medicalization, with physicians, insurance coverage, and changes in regulatory practices playing facilitating roles. In some cases, insurers attempt to counteract medicalization by restricting access. We distinguish mediated and private medical markets, each characterized by differing relationships with corporations, insurers, consumers, and physicians. In the changing medical environment, with medical markets as intervening factors, corporations and insurers are becoming more significant determinants in the medicalization process.

    Full Text Available Abstract Background The aim of this study was to research the feasibility of training mental health consumers as tutors for 4th year medical students in psychiatry. Methods A partnership between a consumer network and an academic unit in Psychological Medicine was formed to jointly develop a training package for consumer tutors and a curriculum in interviewing skills for medical students. Student attitudes to mental health consumers were measured pre and post the program. All tutorial evaluation data was analysed using univariate statistics. Both tutors and students evaluated the teaching program using a 4 point rating scale. The mean scores for teaching and content for both students and tutors were compared using an independent samples t-test. Results Consumer tutors were successfully trained and accredited as tutors and able to sustain delivery of tutorials over a 4 year period. The study found that whilst the medical students started with positive attitudes towards consumers prior to the program, there was a general trend towards improved attitude across all measures. Other outcomes for tutors and students (both positive and negative are described. Conclusions Consumer tutors along with professional tutors have a place in the education of medical students, are an untapped resource and deliver largely positive outcomes for students and themselves. Further possible developments are described.

    This research had two purposes. The first aim was to identify Iranian and Non-Iranian rice consumers based on demographic characteristics and examine difference of these features with buying behaviors. The second purpose of study was to investigate consumer's motivation to buy local rice in Iran. The sample were 1500 people (men and women). The data was collected by using questionnaire based on a face-to-face survey. Chi-square, confirmatory factor analysis, and multiple linear regression were applied to assess collected data by a questionnaire survey. Regarding Iranian local rice buyers, 884 people buy local rice. Chi-square test showed that there is a significant difference between gender, having children, and marital status in buying local rice. Habitual Iranian local rice buyers include: female (51%), people who are more than 45 years old (51%), people with children (63%), people who are living urban (61%), married people (48%) and individuals that their monthly income is between 321.5 and 625 Dollars (53%). Regarding non-Iranian rice buyers, 616 people buy it. Also there is a significant difference between gender, location, marital status, and income in buying local rice. For considering consumers motivation toward buying local rice the econometrical model is used. Model had three aspects including; quality aspects (taste, good appearance), economic aspects (price, convenience, consumer's ethnocentrism), and safety aspects (health, not using pesticides and environment protection) and seven subset. The results of analysis indicated that quality aspects, economic aspects and safety aspects have positive effects on buying Iranian local rice. Also, indicative variables including; taste, good appearance, price, convenience, consumer's ethnocentrism, health, not using pesticides and environment have significant effects on buying it.

    2013-12-01

    Printed education materials are often used to augment healthcare professional's verbal information to consumers so it serves as an important component of symptom management. They also enhance the teaching process and can be used by consumers as a home reference. This study was aimed to interpret consumers' perception on Consumer Medical Information Leaflets (CMILs) on obesity and lipid lowering drugs, on design and layout using the standard method such as Baker Able Leaflet Design (BALD). Convenience sampling was done. The study was conducted over a period of 3 years in community pharmacy settings in Tamil Nadu, India. The Consumer Medical Information Leaflets (CMILs) were randomly collected from different community pharmacies. Total of 19 CMILs which are commonly used by the consumers were collected and CMILs were assessed using BALD assessment tool Results: According to BALD assessment (46.28%) leaflets were rated as 'above standard' and (53.72) leaflets were rated as 'standard or poor' in layout and design since their scores were less than 25. This shows that this issue may be important from the patient's perspective, which may discourage patient from actually reading the CMILs. In India, generally CMILs are continued to be prepared in English and with higher proportion of consumers with English illiteracy. CMILs, which are prepared without taking consideration of reading level of consumers and proper layout and design, may not achieve the intended purpose. This is an important aspect that any company has to reckon while preparing leaflets and at least in some major local languages in which CMILs have to be prepared.

    Direct-to-consumer (DTC) advertising of predictive genetic tests (PGTs) has added a new dimension to health advertising. This study used an online survey based on the health belief model framework to examine and more fully understand consumers' responses and behavioral intentions in response to a PGT DTC advertisement. Overall, consumers reported moderate intentions to talk with their doctor and seek more information about PGTs after advertisement exposure, though consumers did not seem ready to take the advertised test or engage in active information search. Those who perceived greater threat from the disease, however, had significantly greater behavioral intentions and information search behavior.

    1985-01-01

    To gain any insight into consumer attitudes towards radurization in South Africa, it is first of all necessary to pinpoint the consumer. The consumer has to be reached at all levels and must be convinced that radurization is a harmless process. All the indications are there that South African consumer acceptance will come readily once the positive benefits of irradiated food have been adequately publicized. Label and package information create untold problems for the grocery manufacturing and packaging industry. The radiation industry cannot afford to lose consumer confidence. The question is: Must a label be attached to a radurized product or not? The results of the trial marketing campaign have shown that if the correct information is supplied at the right time, the consumer is prepared to accept irradiated food

    Vidal, Leticia; Giménez, Ana; Medina, Karina; Boido, Eduardo; Ares, Gastón

    2015-12-01

    Astringency is one of the most important sensory characteristics of red wine. Although a hierarchically structured vocabulary to describe the mouthfeel sensations of red wine has been proposed, research on consumers' astringency vocabulary is lacking. In this context, the aim of this work was to gain an insight on the vocabulary used by wine consumers to describe the astringency of red wine and to evaluate the influence of wine involvement on consumers' vocabulary. One hundred and twenty-five wine consumers completed and on-line survey with five tasks: an open-ended question about the definition of wine astringency, free listing the sensations perceived when drinking an astringent wine, free listing the words they would use to describe the astringency of a red wine, a CATA question with 44 terms used in the literature to describe astringency, and a wine involvement questionnaire. When thinking about wine astringency consumers freely elicited terms included in the Mouth-feel Wheel, such as dryness and harsh. The majority of the specific sub-qualities of the Mouth-feel Wheel were not included in consumer responses. Also, terms not classified as astringency descriptors were elicited (e.g. acid and bitter). Only 17 out of the 31 terms from the Mouth-feel Wheel were used by more than 10% of participants when answering the CATA question. There were no large differences in the responses of consumer segments with different wine involvement. Results from the present work suggest that most of the terms of the Mouth-feel Wheel might not be adequate to communicate the astringency characteristics of red wine to consumers.

  14. Managing Behaviour of Retail Trade Consumers

    Directory of Open Access Journals (Sweden)

    Budnik Maryna M.

    2014-03-01

    Full Text Available The article is devoted to the problem of management of behaviour of retail trade consumers. It shows importance of this topic at the stage of market changes in economic and social spheres. Generalising theoretical provisions about models of consumer behaviour, the article marks out three main groups of factors that influence them: external, internal and situational. The authors offer to allocate sensor forms of communications into a separate group of factors due to a distinctive property of their impact – orientation at subconsciousness of consumers. The article analyses a psychological process of making a decision on purchase of a commodity and draws a conclusion about necessity of exerting subconsciousness influence upon consumer behaviour using the modern marketing instruments. It develops an improved model of consumer behaviour, which takes into account innovation means of impact on the buyer. The prospect of further development of this direction in science is creation of theoretical methods of managing consumer behaviour on the basis of co-operation of specialists in the field of economy, management, marketing, sociology and psychology, which would be applied in practice of management of trade enterprises.

    Gellad, Ziad F; Lyles, Kenneth W

    2007-06-01

    Since the US Food and Drug Administration (FDA) released new guidelines on broadcast direct-to-consumer advertising in 1997, the prevalence of direct-to-consumer advertising of prescription drugs has increased exponentially. The impact on providers, patients, and the health care system is varied and dynamic, and the rapid changes in the last several years have markedly altered the health care landscape. To continue providing optimal medical care, physicians and other health care providers must be able to manage this influence on their practice, and a more thorough understanding of this phenomenon is an integral step toward this goal. This review will summarize the history of direct-to-consumer drug advertisements and the current regulations governing them. It will summarize the evidence concerning the impact of direct-to-consumer advertising on the public, providers, and the health care system, and conclude with observations regarding the future of direct-to-consumer advertising.

    Despite 35 y of dietary guidance, there has been no substantial shift in consumer compliance. Consumers report that they seek information on nutrition and healthy eating, but most are not paying attention to dietary recommendations. For guidance to be effective, it must be realistic. Even with increasingly detailed nutrition information and evidence that diet affects health outcomes, convenience and taste remain the strongest determinants of food choices. It is up to health educators to clear up confusion and give consumers control with nutrition messages that are realistic, positive, easy to understand, and actionable without an expectation that consumers will surrender foods they love. © 2015 American Society for Nutrition.

  2. Design of resilient consumer products

    DEFF Research Database (Denmark)

    Haug, Anders

    2016-01-01

    Consumer product sustainability is a topic that has been of increasing interest to practice and academia in recent decades. In this context, a widely discussed means of achieving sustainability is to design more durable products, thereby reducing the need for the production of new products....... In particular, the emotional perspective on product durability has received attention in recent design literature, since consumer products are often replaced long before they become physically non-functioning. However, the literature does not provide a full account of the causes of product replacement...... for designers to design resilient consumer products and for researchers to engage in further studies....

    The value of consumer involvement in health services research is widely recognized. While there is a growing body of evidence about the principles of good consumer involvement, there is little research about the effect that involvement can have on the research. This evaluation assessed the level and impact of consumer involvement in the London Primary Care Studies Programme (LPCSP), all of whose individual projects had to demonstrate substantial involvement as a condition of funding. To evaluate consumer involvement in the LPSCP and understand what impact consumers had on the research process and outcomes. A multi-method case study approach was undertaken, using survey techniques, interviews, focus groups, observation and scrutiny of written documents. The overall data set comprised 61 questionnaires, 44 semi-structured interviews, 2 focus groups and 15 hours of observation of meetings. Eleven primary care-based research projects which together made up the LPCSP. An in-depth description of consumer involvement in the Programme was produced. Nine projects had consumers as co-applicants, four projects had been completed before the evaluation began and one was still ongoing at the time of the evaluation. Of the eight projects which have produced final reports, all met their aims and objectives. Consumers had had an additional impact in the research, in the initial design of the study, in recruitment of the research subjects, in developing data collection tools, in collecting the data, in analysis and disseminating the findings. Consumer involvement in National Health Service research is a relatively recent policy development and while there is an increasing amount of literature about how and why consumers should be involved in research, there is less evidence about the impact of such involvement. This evaluation provides evidence about the impact that consumers have not only on the research process but also on the outcomes of the research.

  4. Food irradiation and the consumer

    1990-01-01

    The poster presents a review of research work undertaken on the perception and understanding that consumers have of food irradiation. Food irradiation is not a revolutionary new food processing technique, in fact it is probably one of the most investigated methods presently available. Many countries such as Belgium, France, Denmark, Italy, Spain, the Netherlands and the United States of America permit food irradiation. In Britain it is presently banned although this is currently under review. Awareness of food irradiation by the general public in Britain, although not extensively researched would appear to be increasing, especially in the light of recent media coverage. New quantitative and qualitative work indicates that the general public are concerned about the safety and effectiveness of food irradiation. Research has shown that a large proportion of consumers in Britain, if given the opportunity to purchase irradiated food, would not do so. Further exploration into this response revealed the fact that consumers are confused over what food irradiation is. In addition, there is concern over the detection of irradiated food. The views presented in this paper, of the consumer reaction to irradiated food are of great importance to those involved in the food industry and industries allied to it, which are ultimately dependent on the consumer for their commercial survival.

  5. Biotechnology and Consumer Decision-Making.

    Sax, Joanna K

    Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

    Full Text Available T his article deals with transformation of consumer practices, which become (and maybe have already turned into the dominated form of social behavior and cannot be described within the model of purposeful-rational action. Utilizing the analytical distinction between “doing shopping” as routine practice, related to satisfaction of basic needs, and “going shopping” as pleasure and leasuretime social activity, this article demonstrates series of changes, resulting in generation of new consumer culture. These changes are compared with a range of transfigurations of the consumers’ spaces (trade spaces, which are at once places (scenes, where consumer practices deploy, and the structural condition of their possibility. According to the logic of the modern man, his focus on fast and diverse consumption and his desire of consuming everything in one place, “in one bottle” on the run, the shopping spaces are becoming the center of new industries-cultural, educational, recreational. The modern retail spaces become not only a place of shopping, but also closely incorporate into the social life of the community and turn into the centers of social life. Effectively combining and managing the various scenarios of consumption, the modern retail helps to feel and join the happiness of live communication in the overbounded with the online social contacts, but atomized world, to get rid of the feeling of emotional emptiness. Special design of retail space and the integration of various social technologies, which are created for manipulating the emotional sphere of the customers (non-standard architectural solutions, catchy window dressing, interior design, background music, aromamarketing, psychologically adjusted range of color, taste and tactile solutions create a special entertainment and attraction of space, control the consumer and are ready not only to stimulate the purchase, but to form an unforgettable impressions.

  10. Here Comes the Hyper-Connected Augmented Consumer

    Directory of Open Access Journals (Sweden)

    Stephen Andrew T.

    2017-11-01

    Full Text Available Consumers have become always on and constantly connected. Search costs have plummeted, individuals’ abilities to digitally express themselves and their opinions increased, and the opportunities for superior business and market intelligence for companies have skyrocketed. This has given rise to more, richer, and new sources of consumer data that marketers can leverage, and has fueled the data-driven insights revolution in marketing. But there is more to come very soon. In marketing, we are quickly moving from the age of the connected consumer to the age of the augmented consumer. New technologies like wearable devices, smart sensors, consumer IoT devices, smart homes, and, critically, artificial intelligence ecosystems will not only connect, but will substantially and meaningfully augment the consumer in terms of their thoughts and behaviors. The biggest challenge for marketers will lie in how they approach marketing to this new type of consumer, particularly personal artificial intelligence ecosystems. This means marketing to algorithms, instead of people, and that is very different to how most marketing work is currently done.

  11. Consumer approval of irradiated meat still tentative

    Hollingsworth, P.

    1998-01-01

    Although the FDA has approved irradiation of red meat, consumers may not be so accepting of the use of this technology. Irradiation is a process used to improve food safety in food products susceptible to disease-causing microorganisms. The red meat ruling was widely praised by federal officials and food industry leaders, but consumers seem less sure. Indeed, on the night of the red meat announcement last December, CBS Evening News reported that over 70 percent of U.S. consumers would not knowingly eat irradiated food. There is hope, however, as a study by the Center for Consumer Research at the University of California, Davis, revealed that consumer interest in buying irradiated food can be substantially improved by providing consumers with information, thereby enabling them to see the benefits and to overcome the myths of irradiation

    2017-04-01

    The aim of the review was to describe consumer-led health-related online sources and their impact on consumers. The review was carried out as an integrative literature review. Quantisation and qualitative content analysis were used as the analysis method. The most common method used by the included studies was qualitative content analysis. This review identified the consumer-led health-related online sources used between 2009 and 2016 as health-related online communities, health-related social networking sites and health-related rating websites. These sources had an impact on peer support; empowerment; health literacy; physical, mental and emotional wellbeing; illness management; and relationships between healthcare organisations and consumers. The knowledge of the existence of the health-related online sources provides healthcare organisations with an opportunity to listen to their consumers' 'voice'. The sources make healthcare consumers more competent actors in relation to healthcare, and the knowledge of them is a valuable resource for healthcare organisations. Additionally, these health-related online sources might create an opportunity to reduce the need for drifting among the healthcare services. Healthcare policymakers and organisations could benefit from having a strategy of increasing their health-related online sources.

    1999-01-01

    This report provides an overview of public readiness to deal with deregulation of the electric power industry , based on an analysis of public reaction to the deregulation of the transportation, telecommunications and natural gas industries which already have taken place. The report also examines the reasons why residential consumers have reason to be wary of deregulation. These include the likelihood of slow development of the intended competition, the consequent limits on consumer choices, the possibility of increased prices, decreased quality of service and erosion of social values such as affordability and accessibility. The report concludes with a number of recommendations aimed at ensuring the existence of workable competition for residential consumers, that reliable and meaningful information is available as competition in deregulated markets gets underway, that independent sources of information are widely available, and that basic consumer protection against deceptive and borderline marketing practices, a regulatory oversight mechanism and public reporting mechanisms are in place before competition begins. 33 refs

    2012-01-01

    This paper analyzes consumer satisfaction in the energy sector in Kenya to assess the quality and level of service delivery. By use of the European Consumer Satisfaction Index (ECSI), the paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. The findings are that consumer satisfaction is highest in the renewable energy sub sector at 74.7% followed by petroleum at 62.8%. The electricity sub sector has the lowest consumer satisfaction of 53.06%. Further, it is found that the image of renewable energy providers is also the highest at 72.5% followed by that of petroleum companies at 63.1%. In the electricity sub sector, perceived value scored the highest at 64.2%. The paper concludes that image of a service provider, loyalty of consumers, consumer expectations, perceived value, perceived quality and the way complains are handled are very important factors that determine consumer satisfaction levels. It is recommended that for monitoring and evaluation purposes in the performance of the energy sector, the Energy RegulatoryCommission(ERC) could use the consumer satisfaction index level to evaluate whether the regulatory policies and their implementation are bearing fruit where a high index would be associated with good performance and vice versa. - Highlights: ► The paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. ► Consumer satisfaction is highest in the renewable energy sub sector at 74.7%. ► The electricity sub sector has the lowest consumer satisfaction of 53.06%. ► Image of renewable energy providers is also the highest at 72.5%. ► Factors explaining consumer satisfaction are; Image, consumers’ loyalty, expectations, perceived value, and perceived quality.

  3. From Consumerism to the Empowerment of Consumers: The Case of Consumer Oriented Movements in France

    Directory of Open Access Journals (Sweden)

    Sophie Dubuisson-Quellier

    2010-06-01

    Full Text Available Political consumerism was developed during the 19th century and expanded at the turn of the century through social movements aimed at empowering civil society in the market. Many of these movements succeeded in building power on the consumption side. Today, we still witness several forms of political consumerism. This contribution explores the possibilities and limits of consumer involvement in sustainable consumption. The main finding of this study of the political organization of consumers is that the market may not be the only arena for changing consumer behavior. Instead, social constraint and political empowerment seem to be rather more efficient.

This study examines the consumer engagement with chardonnay, and contributes evidence-based research to inform future wine-business strategy. A population sample was recruited to be representative of Australian consumers. An online survey of 2,024 Australian wine consumers was conducted, 1,533 (76% of whom actually consumed chardonnay. This paper focuses only on those who consumed chardonnay. Males purchased and consumed larger quantities of chardonnay, although marginally more females consumed it. Chardonnay is considered to be characterized by full, lingering, and fruity flavors, as well as yellow color. Chardonnay is associated with dinner parties and at-home consumption. The vast majority of participants liked and had a positive perception of chardonnay. The target market for chardonnay is not only females; in fact, males appear to be the main consumers of this varietal by volume. Marketing and promotion campaigns should leverage the findings to retain current and win back other consumers. This is the first research to provide empirical explanations of consumer engagement with chardonnay, and to contribute evidence-based research in this regard.Keywords: chardonnay, consumer behavior, wine style, wine consumption, Australia

    A simulated supermarket setting (SSS) test was conducted to determine whether consumers (n = 126) would purchase irradiated poultry products, and the effects of marketing strategies on consumer purchase of irradiated poultry products. Consumer preference for irradiated poultry was likewise determined using a home-use test. A slide program was the most effective educational strategy in changing consumers' purchase behavior. The number of participants who purchased irradiated boneless, skinless breasts and irradiated thighs after the educational program increased significantly from 59.5 and 61.9% to 83.3 and 85.7% for the breasts and thighs, respectively. Using a label or poster did not increase the number of participants who bought irradiated poultry products. About 84% of the participants consider it either 'somewhat necessary' or 'very necessary' to irradiate raw chicken and would like all chicken that was served in restaurants or fast food places to be irradiated. Fifty-eight percent of the participants would always buy irradiated chicken if available, and an additional 27% would buy it sometimes. About 44% of the participants were willing to pay the same price for irradiated chicken as for nonirradiated. About 42% of participants were willing to pay 5% or more than what they were currently paying for nonirradiated chicken. Seventy-three percent or more of consumers who participated in the home-use test (n = 74) gave the color, appearance, and aroma of the raw poultry products a minimum rating of 7 (= like moderately). After consumers participated in a home-use test, 84 and 88% selected irradiated thighs and breasts, respectively, over nonirradiated in a second SSS test

    The objectives of the present study were (1) to compare the relative importance of price, processing time, texture and intramuscular fat in purchase intention of dry-cured ham through conjoint analysis, (2) to evaluate the effect of dry-cured ham appearance on consumer expectations, and (3) to describe the consumer sensory preferences of dry-cured ham using external preference mapping. Texture and processing time influenced the consumer preferences in conjoint analysis. Red colour intensity, colour uniformity, external fat and white film presence/absence influenced consumer expectations. The consumer disliked hams with bitter and metallic flavour and with excessive saltiness and piquantness. Differences between expected and experienced acceptability were found, which indicates that the visual preference of consumers does not allow them to select a dry-cured ham that satisfies their sensory preferences of flavour and texture.

    2011-01-01

    Full Text Available Perception involves the collection, processing and interpretation of information through sensory receptors and represents the reality of an individual. Collecting customer information is imperative for marketing, because consumers are in the focus of defining all its objectives, strategies and plans. The result of the perception depends on a number of factors and that is why people do not experience stimuli in the same way. A marketing research of consumer perceptions has been carried out in order to identify the habits and understand the behavior of consumers when choosing products with special emphasis on the influence of perception, stimuli from the environment and perceptions of risk in their decision. .

    Directory of Open Access Journals (Sweden)

    Mihaela-Irina IONESCU

    2015-07-01

    Full Text Available The article provides an image to the point on information provided to consumers before the conclusion of a credit contract, starting with the importance of information and ending with the legal framework. A high consumer protection may be achieved primarily through consumer information. The complexity of banking services but also the vulnerability of consumers in relation to the banks and the unbalanced relationship led to the need to develop specific legislation that clearly establishes the rights and obligations of the parties of a credit agreement for consumers. In this regard, in 2008, after many debates, Directive 2008/48/EC of the European Parliament and of the Council on credit agreements for consumers was adopted. At national level, the Directive was transposed by the Government Emergency Ordinance no. 50/2010 on credit agreements for consumers. Taking into account national specificities, such as lack of experience of consumers in financial products, the irresponsible lending and the unfair practices of creditors, the national act includes wider provisions than the European Directive, such as those relating to fees limitations or those related to the calculation of the variable interest rate. Also the GEO no 50/2010 applies to all credit agreements concluded by consumers and creditors. As regards the advertising, any advertisement shall include a series of standard information. Also, pre-contractual information is standard information, is provided to consumers 15 days before the contract is concluded and is transmitted through the “European Consumer Credit Information sheet Standard”. The article presents when, how and what information should be given to consumers and insists on the importance of annual percentage rate and to what consumers should pay attention in order to be able to compare different offers.

    2016-12-01

    Consumers can be important active contributors to a sustainable society by selecting food choices that are both healthy and produced respecting environmental and socially ethical standards. The current study investigates five consumer behavioural factors - namely, perceived consumer effectiveness (PCE); environmental conscious behaviour; concerns for ethical food production; health conscious lifestyle; and healthy dietary patterns. The key interest of the study lies in exploring the moderating role of PCE - the extent to which the consumer believes that his/her own efforts can make a difference - in these interrelationships. The empirical analysis was conducted through an online survey of food consumers implemented in three markets - the US, the UK and Germany. Findings indicate that for individuals with higher levels of PCE, who are environmental conscious and ethically concerned, information on food labels relating to environmental and social issues represents value by itself. Interestingly, health and nutrition information on food labels was not perceived valuable by consumers with high PCE. The predictive effects of various socio-demographic variables on PCE, consumer environmental and health consciousness are discussed. Cross-cultural differences are also outlined. The results of this research may contribute to the development of environmental policies and communication strategies of the food industry to enhance perceived consumer effectiveness among consumers. Improved PCE, in turn, may catalyze consumers' environmental behaviour and ethical concerns in relation to consumption of food products with environmental and social information.

    1989-01-01

    There has been a growing world-wide shift in consumer consciousness during the 1980s. More and more, consumers are challenging the conclusions and assurances of authorities and demanding to be better informed so that they can draw their own conclusions and make their choices accordingly. The viewpoint of these consumers is articulated, so that the specialists involved in the radurization of food can have a better understanding of what they are dealing with

    Flavor is an important factor in consumer selection of cheeses. Mild Cheddar cheese is the classification used to describe Cheddar cheese that is not aged extensively and has a "mild" flavor. However, there is no legal definition or age limit for Cheddar cheese to be labeled mild, medium, or sharp, nor are the flavor profiles or flavor expectations of these cheeses specifically defined. The objectives of this study were to document the distinct flavor profiles among commercially labeled mild Cheddar cheeses, and to characterize if consumer preferences existed for specific mild Cheddar cheese flavors or flavor profiles. Flavor descriptive sensory profiles of a representative array of commercial Cheddar cheeses labeled as mild (n= 22) were determined using a trained sensory panel and an established cheese flavor sensory language. Nine representative Cheddar cheeses were selected for consumer testing. Consumers (n= 215) assessed the cheeses for overall liking and other consumer liking attributes. Internal preference mapping, cluster analysis, and discriminant analysis were conducted. Mild Cheddar cheeses were diverse in flavor with many displaying flavors typically associated with more age. Four distinct consumer clusters were identified. The key drivers of liking for mild Cheddar cheese were: color, cooked/milky, whey and brothy flavors, and sour taste. Consumers have distinct flavor and color preferences for mild Cheddar cheese. These results can help manufacturers understand consumer preferences for mild Cheddar cheese.

    Assessing consumer perceptions and willingness to pay for genetically modified (GM) foods has been one of the most active areas of empirical research in agricultural economics. Researchers over the past 15 years have delivered well over 100 estimates of consumers' willingness to pay for GM foods using surveys and experimental methods. In this review, we explore a number of unresolved issues related to three questions that are critical when considering the sum of the individual contributions that constitute the evidence on consumer preferences for GM foods.

    Rubin, P H

    2001-01-01

    Pharmaceutical companies have greatly increased their level of "direct-to-consumer" (DTC) advertising in recent years. For 1998, estimates are that over $1.1 billion was spent on this form of advertising, increased from $850 million in 1997 and $600 million in 1996. In 1998, 84 separate drugs were advertised to consumers. The impetus was a decision in August of 1997 by the Food and Drug Administration to reduce the restrictions on DTC advertising on television. As a result, such ads have become very common on TV, and 32 products were advertised on TV in 1998. Pharmaceutical companies advertise because they think that advertising will make money for them. But how will this make money? It will make money by providing consumers with the information they need to make proper decisions about medication. That is, DTC advertising is profitable exactly because it empowers consumers and enables them to purchase useful drugs. The goals of advertising companies and consumers are both for consumers to have information about the most beneficial drug for particular conditions, and so advertising is beneficial both to manufacturers and to consumers. This article describes emerging trends in DTC within the context of the life sciences sector.

    1995-01-01

    Using the consumer-oriented approach of social and commercial marketers, this article presents a process for crafting messages designed to improve people's health behaviors. The process, termed consumer-based health communications (CHC), transforms scientific recommendations into message strategies that are relevant to the consumer. The core of CHC is consumer research conducted to understand the consumer's reality, and thereby allowing six strategic questions to be answered. The immediate result of the CHC process is a strategy statement--a few pages that lay out who the target consumer is, what action should be taken, what to promise and how to make the promise credible, how and when to reach him or her, and what image to convey. The strategy statement then guides the execution of all communication efforts, be they public relations, mass media, direct marketing, media advocacy, or interpersonal influence. It identifies the most important "levers" for contact with the consumer. Everyone from creative specialists through management and program personnel can use the strategy statement as a touchstone to guide and judge the effectiveness of their efforts. The article provides a step by step illustration of the CHC process using the 5 A Day campaign as an example.

    2014-10-01

    This study established attractive attributes and consumer desires for fresh tomatoes. Three focus groups (n = 28 participants) were conducted to explore how consumers perceived tomatoes, including how they purchased and consumed them. Subsequently, an Adaptive Choice Based Conjoint (ACBC) survey was conducted to understand consumer preferences toward traditional tomatoes. The ACBC survey with Kano questions (n = 1037 consumers in Raleigh, NC) explored the importance of color, firmness, size, skin, texture, interior, seed presence, flavor, and health benefits. The most important tomato attribute was color, then juice when sliced, followed by size, followed by seed presence, which was at parity with firmness. An attractive tomato was red, firm, medium/small sized, crisp, meaty, juicy, flavorful, and with few seeds. Deviations from these features resulted in a tomato that was rejected by consumers. Segmentations of consumers were determined by patterns in utility scores. External attributes were the main drivers of tomato liking, but different groups of tomato consumers exist with distinct preferences for juiciness, firmness, flavor, and health benefits. Conjoint analysis is a research technique that collects a large amount of data from consumers in a format designed to be reflective of a real life market setting and can be combined with qualitative insight from focus groups to gain information on consumer consumption and purchase behaviors. This study established that the most important fresh tomato attributes were color, amount of juice when sliced, and size. Distinct consumer clusters were differentiated by preference for color/appearance, juiciness and firm texture. Tomato growers can utilize the results to target attributes that drive consumer choice for fresh tomatoes. © 2014 Institute of Food Technologists®

    2010-10-01

    This article investigates the effect of optimal distinctiveness on consumer product consumption. The authors argue that consumers acquire and display material possessions to restore their optimal levels of distinctiveness. Results showed that placing consumers in a state of low distinctiveness increased desire to acquire distinctive products, whereas perceptions of high distinctiveness reduced desire to acquire such products. Consumers' desire for distinctiveness-related products held true for various consumer choices, including willingness to pay more for limited-edition products and preference for unpopular gifts. This finding has implications for understanding consumer choice in expressing identity. © 2010 The Authors. Scandinavian Journal of Psychology © 2010 The Scandinavian Psychological Associations.

This article aims to identify the taxonomy of readership categories that reflect the complexity of how health care consumers interact with DTCA, with particular focus on individuals' perceptions of print DTCA in popular magazines. Respondent-driven sampling was used to recruit 18 male and female magazine readers and 18 male and female prescription medication users aged 18–71 years. Semi-structured, in-depth interviews with consumers about their attentiveness, motivations, perceived value, and behavioral responses to DTCA were conducted. The analyses were guided by principles of grounded theory analysis; four categories that vary in consumers' attentiveness, motivations, perceived value, and behavioral responses to DTCA were identified. Two categories – the lay physician and the informed shopper – see value in information from DTCA and are likely to seek medical care based on the information. One category – the voyeur – reads DTCA, but is not likely to approach a clinician regarding advertised information. The fourth category – the evader – ignores DTCA and is not likely to approach a clinician with DTCA information. Responses to DTCA vary considerably among consumers, and physicians should view patients' understanding and response to DTCA within the context of their health-related needs. Patients' comments

  13. Tourism law: from traveller to consumer

    2016-09-01

    Full Text Available The law on tourism – “tourism law” for some authors – is the instrument that has been used to turn the tourist into a consumer. Travellers are increasingly aware of the rights they can exercise. Incorporating the regulation of combined travel contracts (separate tourist services sold for an overall price into the body of consumer regulation and air passenger protection has made a definitive contribution to establishing this condition. Tourist contracts involving consumers have ended up in the courts, which have already had the opportunity to interpret the regulations and orient them towards the most protectionist positions for consumers. With the addition of new consumption habits and new types of contracting the future of this field looks far from static.

  15. THE CONCEPT OF REFLEXIVE MANAGEMENT OF CONSUMER DEMAND

    2017-11-01

    Full Text Available Development of theoretical approaches of demand management is conducted from the moment of awareness of the importance of this concept. Many models of individual consumers were developed. However, to predict the reaction of consumers to the commercial policy of the enterprise, exact methods do not exist yet because the available ones are mostly empirical in nature. Models of behaviour often do not provide the expected result because they use an erroneous approach to the analysis of the mechanism of demand formation. The subject of the research is the theoretical and methodological basis, methods of assessment, and reflexive management of consumer demand of commercial enterprises. The purpose of the paper is developing a concept of reflexive management of consumer demand. To achieve the research goal, the following tasks are set and solved: to substantiate the theoretical and methodological foundations of reflexive consumer management, to analyse existing approaches to the modelling of consumer behaviour; to improve the model of consumer behaviour; to develop a concept of reflexive management of consumer behaviour. Methodology. In the paper, we use such methods and approaches to research as: reflexive approach (phenomenological method, behavioural economic theory, marketing approach, abstract-logical analysis, analysis of theoretical approaches to the modelling of consumer behaviour. Results. Modern approaches to modelling of consumer behaviour are mostly empirical in nature and have shortcomings of general models. In them, there is no description of specific situations of the purchase of goods. They cannot be quantified. Therefore, they cannot be practical models. But they have a weighty advantage in a comprehensive look at motivated purchases, what makes it possible to evaluate the relevance of individual variables and to understand the fundamental processes of consumer behaviour. It makes possible to identify the variables necessary for the

The sample included 330 students from Faculty of Economics in Podgorica, divided into six subsample groups: consumers who do not purchase sport goods at all, then consumers who purchase sport goods less than ones a month, next 1–3 a month, 4–6 a month, 7–9 a month, as well as consumers who purchase sport goods more than 10 times a month. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analyzed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Based on the statistical analyses it was found that significant differences occur at multivariate level, as well as between all three variables at a significance level of (p=.000. Hence, it is interesting to highlight that it was found there were significant differences showed up between the consumers who purchase sport goods. The significant differences were found in two of three variables, while the consumers who purchase sport goods less than 3 times a moths had much more negative attitudes toward advertising though sport.

    Full Text Available The aim of our paper is to investigate the links between terminal and instrumental values, personality types, consumer attitudes and behavior that are relevant to marketing decision-making. The understanding of the personality and values of individual consumers should enable us to predict their preferences and behavior. Our set of consumer attitudes and behavior includes reported peer influence on shopping behavior, consumer ethnocentrism, value shopping and hedonism in shopping. Two multidimensional statistical approaches are considered: a cluster analysis of the individual’s personality and values and a factor analysis of consumer attitudes and behavior. An analysis of data from a representative sample of 1,094 Slovenian consumers (PGM, Valicon, 2007 reveals five clusters: conscientious-non-agreeable consumers differ in their consumer attitudes from extroversive consumers, neurotic-with-low-values, open-with-high-values and agreeable-conscious-non-open consumers. Implications for marketing decision-making and strategy development are considered, together with a possible extension of the study to multiple national groups of consumers from Central and Eastern Europe (CEE.

    Full Text Available We live in a society where the consumer, due to the diversity and abundance of products and services whose characteristics are becoming more similar, has to make choices that are increasingly difficult. Another aspect that has led to a profound transformation of the consumer behavior is due to the large volume of information, supplied by the Internet, information which in some cases is not accurate, but is decisively influencing the consumer. In equal measure, the difficulty of making a purchasing decision is caused by the fact that with the opening to the global market, where the products and services were depersonalized, gaining common features, and where the concept of quality tends to no longer relate to the same standards as a few decades ago, having suffered major changes. The quality of products is a fundamental requirement of competitiveness, and quality assessment is a personal right of the consumer, because this is a direct effect of quality of life.

    This study aims to describe a cycle of development leading to sustainable methods for involving consumers in the management of a program commissioning health technology assessment. Staff time was dedicated to developing procedures for recruiting and briefing consumers to participate in prioritizing, commissioning, and reporting research. Resources and support were developed in light of early feedback from consumers and those working with them. These were piloted and amended before being used routinely. Over 4 years, procedures and resources have been developed to support six consumers attending seven to eight prioritization meetings a year; thirty to forty-five consumers each year commenting on research need for particular topics; thirty consumers a year commenting on research proposals, and twenty a year commenting on research reports. The procedures include clear job descriptions, induction and development days, clear briefing materials, payment for substantial tasks, and regularly seeking feedback to improve procedures. Explicit, inclusive, and reproducible methods for supporting consumer involvement that satisfy National Health Service policy recommendations for involving consumers in research require dedicated staff time to support a cycle of organizational development.

  2. Neuromarketing and consumer neuroscience: contributions to neurology

    2013-01-01

    Background ‘Neuromarketing’ is a term that has often been used in the media in recent years. These public discussions have generally centered around potential ethical aspects and the public fear of negative consequences for society in general, and consumers in particular. However, positive contributions to the scientific discourse from developing a biological model that tries to explain context-situated human behavior such as consumption have often been neglected. We argue for a differentiated terminology, naming commercial applications of neuroscientific methods ‘neuromarketing’ and scientific ones ‘consumer neuroscience’. While marketing scholars have eagerly integrated neuroscientific evidence into their theoretical framework, neurology has only recently started to draw its attention to the results of consumer neuroscience. Discussion In this paper we address key research topics of consumer neuroscience that we think are of interest for neurologists; namely the reward system, trust and ethical issues. We argue that there are overlapping research topics in neurology and consumer neuroscience where both sides can profit from collaboration. Further, neurologists joining the public discussion of ethical issues surrounding neuromarketing and consumer neuroscience could contribute standards and experience gained in clinical research. Summary We identify the following areas where consumer neuroscience could contribute to the field of neurology: First, studies using game paradigms could help to gain further insights into the underlying pathophysiology of pathological gambling in Parkinson’s disease, frontotemporal dementia, epilepsy, and Huntington’s disease. Second, we identify compulsive buying as a common interest in neurology and consumer neuroscience. Paradigms commonly used in consumer neuroscience could be applied to patients suffering from Parkinson’s disease and frontotemporal dementia to advance knowledge of this important behavioral symptom

    Full Text Available Although consumers’ emotional attachments to brands have been measured and written about in several contexts, little is known about where a “love” type consumer-brand relationship is rooted and what meaning the consumer gives to such deep experience. The current study aims to extend the discussion of the brand experience dimensions and to form the brand love, focusing on the members of the youngest consumer segment. Based on the introspective written narratives using an international sample of young consumers, this qualitative study offers a holistic view of forming brand love. The findings underscore the relevance of a first encounter with a brand. Adapting the ecological systems theory, the authors identified three social systems from where the informants got impulses to reach their loved brands.

    1993-01-01

    Sales of irradiated foods clearly indicate that North American consumers appreciate the value of irradiated foods. The results of North American consumer attitude surveys can be used to predict acceptance of quality irradiated foods, especially when improved food safety is the perceived benefit. Consumers perceive the most benefit when irradiation is used to improve food safety or to reduce the chemicals used on foods. Information about irradiation seems to increase consumer willingness to buy. Consumer activists continue to attempt to prevent the sale of labelled irradiated foods, but they have not been successful. (author)

  16. Awakened Oscillations in Coupled Consumer-Resource Pairs

    2014-01-01

    Full Text Available The paper concerns two interacting consumer-resource pairs based on chemostat-like equations under the assumption that the dynamics of the resource is considerably slower than that of the consumer. The presence of two different time scales enables to carry out a fairly complete analysis of the problem. This is done by treating consumers and resources in the coupled system as fast-scale and slow-scale variables, respectively, and subsequently considering developments in phase planes of these variables, fast and slow, as if they are independent. When uncoupled, each pair has unique asymptotically stable steady state and no self-sustained oscillatory behavior (although damped oscillations about the equilibrium are admitted. When the consumer-resource pairs are weakly coupled through direct reciprocal inhibition of consumers, the whole system exhibits self-sustained relaxation oscillations with a period that can be significantly longer than intrinsic relaxation time of either pair. It is shown that the model equations adequately describe locally linked consumer-resource systems of quite different nature: living populations under interspecific interference competition and lasers coupled via their cavity losses.

    Contemporary mental health policies call for greater involvement of mental health service consumers in all aspects and at all levels of service planning, delivery, and evaluation. The extent to which consumers are part of the decision-making function of mental health organizations varies. This systematic review synthesizes empirical and review studies published in peer-reviewed academic journals relating to consumers in leadership roles within mental health organizations. The Cochrane Library, Medline, and PsycINFO were searched for articles specifically analysing and discussing consumers' mental health service leadership. Each article was critically appraised against the inclusion criteria, with 36 articles included in the final review. The findings of the review highlight current understandings of organizational resources and structures in consumer-led organizations, determinants of leadership involvement, and how consumer leadership interacts with traditional mental health service provision. It appears that organizations might still be negotiating the balance between consumer leadership and traditional structures and systems. The majority of included studies represent research about consumer-run organizations, with consumer leadership in mainstream mental health organizations being less represented in the literature. Advocates of consumer leadership should focus more on emphasizing how such leadership itself can be a valuable resource for organizations and how this can be better articulated. This review highlights the current gaps in understandings of consumer leadership in mental health, including a need for more research exploring the benefits of consumer leadership for other consumers of services. © 2016 Australian College of Mental Health Nurses Inc.

    Full Text Available Unlike other advertising mediums such as TV commercials or online advertising, people involuntarily receive sport advertisements; they prefer to watch the game for the sporting action than the regular advertisements. However, it is important to analyse their general attitudes among various questions, mostly due to the reason it varies from demographic group to demographic group. Hence, this research was aimed at gaining relevant knowledge about the attitudes of Serbian consumers toward advertising through sport among the question how often consumers purchase sporting goods. The sample included 173 respondents, divided into six subsample groups: consumers who do not purchase sport goods at all, then consumers who purchase sport goods less than ones a month, next 1–3 a month, 4–6 a month, 7–9 a month, as well as consumers who purchase sport goods more than 10 times a month. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analysed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Based on the results it was concluded that significant differences occur at multivariate level, as well as between one of three variables at univariate level (p=.05. It is interesting to highlight that most of potential consumers (n=146 have recognized themselves in two categories: as consumers who purchase sport goods less than ones a month and one to three times a months, while there were no differences among the groups. If we take a look into previous investigations, it is interesting there are some opposite results, and the recommendations for further research are directed to spread out the sample a little bit more, mostly due to the reason the consumers who had a more negative attitudes were in the group that didn’t purchase the sport goods at all.

Methods: One thousand and seven adult consumers (aged 20–50 years were randomly selected from all over South Korea between November 1 and 9, 2010. We surveyed the origin and degree of their concern and their need for information and education regarding nanomaterials. Results: Analysis of the survey results showed no significant differences in responses by sex, age, and level of education, but significant differences were found in responses based on average monthly household income. Our research showed that consumers have vague expectations for and positive image of nanotechnology and nanoproducts but do not clearly understand what they are. In addition, we found that preparing and disseminating information to consumers is required in order to provide correct information about nanotechnology to the public. Conclusion: A communication system should be established among the multiple stakeholders involved

    To examine consumers' attitudes toward direct-to-consumer advertising (DTCA) for prescription drugs in Korea. We conducted a survey of 350 patients visiting community pharmacies to fill their prescriptions. Consumers' attitudes toward DTCA were assessed in terms of whether they felt DTCA was necessary, their trust in the information provided by DTCA, and their intention to use the information provided by DTCA. We examined consumers' preferences regarding the regulation of DTCA and their expectations of the effects of DTCA. About 60% of the respondents responded that DTCA is necessary and that they intended to use the information from DTCA. Less than half of the respondents reported that they would trust DTCA information. About 70% of the participants expressed the need for prior vetting of the DTCA content. Respondents had the highest expectation on the effect of DTCA as an information source for patients. Positive consumer expectations regarding the effects of DTCA were significantly associated with positive consumer attitudes toward DTCA (odds ratio=4.70, 95% confidence interval: 2.25-9.82). This study provides evidence that consumers in South Korea generally have positive attitudes toward DTCA. However, most of the respondents wanted a prior examination system of DTCA content to ensure that the information conveyed to them via DTCA was trustworthy. Policy-makers should be cautious and well-prepared if they decide to introduce DTCA in Korea. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    A job shop has an arrangement where similar machines (Direct consumables) are grouped together and use indirect consumables to produce a product. The indirect consumables include hack saw blades, emery paper, painting brush etc. The job shop is serving various orders at a particular time for the optimal operation of job shop. Forecasting is required to predict the demand of direct and indirect consumables in a job shop. Forecasting is also needed to manage lead time, optimize inventory cost and stock outs. The objective of this research is to obtain the forecast for indirect consumables. The paper shows how job shop can manage their indirect consumables more accurately by establishing a new technique of forecasting. This results in profitable use of job shop by multiple users.

  6. Interaction in consumers attitudes and behavior

    2007-01-01

    Full Text Available Having in mind a fact that consumers represent the central aspect of the companies' demand, consumer behavior must be the focal point of marketing research as well as the central topic in the entire marketing system. The initial and the most fundamental marketing activity is the research of consumer behavior. It is only after the analysis of the collected relevant data on current and potential buyers, that the companies can implement other marketing activities such as competition analysis, sales forecast, measuring the market potential as well as the market share in order to create the appropriate marketing mix of the company. Numerous factors influence behavior of the consumers, however, one can conclude that the attitudes play very important role in the psychological analysis of the consumer behavior. Attitude recognition gives us a chance to analyze past and predict future behaviors. Often the behavior appears as the consequence of the formed attitudes. Weather the behavior results from the attitude and whether or not it is in accordance with this attitude, depends on the strength of the attitude as well as on the influence of other environmental factors.

    Instant noodles are widely consumed in Asian countries. The Korean population consumed the largest quantity of instant noodles in the world in 2008. However, few studies have investigated the relationship between instant noodles and nutritional status in Koreans. The objective of this study was to examine the association between instant noodle consumption and food and nutrient intake in Korean adults. We used dietary data of 6,440 subjects aged 20 years and older who participated in the Korean National Health and Nutrition Examination Survey III. The average age of the instant noodle consumers (INC) was 36.2 and that of the non-instant noodle consumers (non-INC) was 44.9; men consumed more instant noodles than women (P instant noodles may lead to excessive intake of energy, fats, and sodium but may also cause increased intake of thiamine and riboflavin. Therefore, nutritional education helping adults to choose a balanced meal while consuming instant noodles should be implemented. Additionally, instant noodle manufacturers should consider nutritional aspects when developing new products.

Firstly, smart metering deployment challenges emerging and conventional tariffs, which modify a consumer behavior and thus, the entire electric energy market can be optimized since the customer is motivated to consume less energy. Secondly, the authors illustrate changes in electricity quality, which have an impact on consumer relations with utility. Additionally, two main indices of grid resilience – SAIDI and SAIFI – are exemplified to reveal the improvement potential of smart metering implementation in certain regions of Russia that also influence the consumer. Finally, in-home display and privacy problem directly reflect the consumer’s behavior, thus the private life rights should not be violated as they are guaranteed by law.

    Consumer directed care (CDC) is currently being embraced internationally as a means to promote autonomy and choice for consumers (people aged 65 and over) receiving community aged care services (CACSs). CDC involves giving CACS clients (consumers and informal carers of consumers) control over how CACSs are administered. However, CDC models have largely developed in the absence of evidence on clients' views and preferences. We explored CACS clients' preferences for a variety of CDC attributes and identified factors that may influence these preferences and potentially inform improved design of future CDC models. Study participants were clients of CACSs delivered by five Australian providers. Using a discrete choice experiment (DCE) approach undertaken in a group setting between June and December 2013, we investigated the relative importance to CACS consumers and informal (family) carers of gradations relating to six salient features of CDC (choice of service provider(s), budget management, saving unused/unspent funds, choice of support/care worker(s), support-worker flexibility and level of contact with service coordinator). The DCE data were analysed using conditional, mixed and generalised logit regression models, accounting for preference and scale heterogeneity. Mean ages for 117 study participants were 80 years (87 consumers) and 74 years (30 informal carers). All participants preferred a CDC approach that allowed them to: save unused funds from a CACS package for future use; have support workers that were flexible in terms of changing activities within their CACS care plan and; choose the support workers that provide their day-to-day CACSs. The CDC attributes found to be important to both consumers and informal carers receiving CACSs will inform the design of future CDC models of service delivery. The DCE approach used in this study has the potential for wide applicability and facilitates the assessment of preferences for elements of potential future aged care

These changes are reflected in the “Official statistical methodology for the organization of statistical observation of consumer prices for goods and services and the calculation of the consumer price index”, approved by order of the Federal State Statistics Service of December 30, 2014 no. 734. The essence of innovation is the use of mathematical methods in determining the range of studies objects of trade and services, in calculating the sufficient observable price quotes based on price dispersion, the proportion of the observed product (service, a representative of consumer spending, as well as the indicator of the complexity of price registration. The authors analyzed the mathematical calculations of the required number of quotations for observation in the Volgograd region in 2016, the results of calculations are compared with the number of quotes included in the monitoring. The authors believe that the implementation of these mathematical models allowed to substantially reduce the influence of the subjective factor in the organization of monitoring of consumer prices, and therefore to increase the objectivity of the resulting statistics on consumer prices and inflation. At the same time, the proposed methodology needs further improvement in terms of payment for goods, products (services by representatives having a minor share in consumer expenditure.

    2014-01-01

    Although exposure to direct-to-consumer prescription drug advertising (DTCA) is reported to influence the public's beliefs about diseases, no research has investigated how DTCA may affect the extent of consumers' optimistic bias about the future risk of diseases. Based on a survey with members of an online consumer panel (n = 699), the current study revealed that: (a) Consumers exhibited a tendency to believe they were at less risk of developing clinical depression in the future than their peers, demonstrating an optimistic bias. (b) Exposure to antidepressant DTCA acted to reduce the extent of such bias, especially when consumers were less skeptical of prescription drug advertising. When consumers were highly skeptical, DTCA exposure did not significantly relate to the extent of optimistic bias. (c) Once formed, the extent of optimistic bias negatively related to consumers' intention to seek information about depression. Implications of the research for the theory and practice of DTCA were discussed.

    2016-01-01

    As far as the rights of consumers are concerned, the International Organization of Consumer's Union (IOCU) in 1983 has specified about the eight rights of a consumer. The Consumer Protection Act (CPA), 1986 then prescribed six "Rights of Consumers," which are protected under the act. However, these rights can be observed in the ancient Indian texts such as Brihat-trayee , Narad Smruti , and Kautilya Arthashastra ., in the form of rights given to patients. For the purpose of present study, the implemented methodology includes - (1) study of the consumer rights described by IOCU and CPA, (2) detailed review of literature for observance of replication of these consumer rights in the ancient Indian texts and (3) a comparative study of the present consumer rights with the rights of patients observed in ancient Indian texts. This study shows that the substance of consumer rights is not a recent evolution, but the foundation of these rights has been laid well beforehand in the ancient times, which were provided to the patients by medical profession as well as by the rulers. The current scenario of protection of consumer rights is the replication of this ancient practice only.

    This is the FIRST of TWO linked articles on consumer behavioural analysis. Cognitive theories have dominated the field of consumer behaviour for the last few decades, however, an observed lack of consistency between attitudes and behaviour has suggested the need to investigate more thoroughly situational and behavioural variables. Consumer behaviour analysis can be viewed as an alternative theoretical approach that emphasizes situational variables and measures of behaviour. Within consumer be...

    2013-01-01

    Based on a survey with members of an online consumer panel (N= 699), this study revealed that: (a) a substantial percentage of consumers held misperceptions about the chemical imbalance theory of depression; (b) personal and interpersonal experiences with depression positively related to such misperceptions; (c) overall, exposure to direct-to-consumer (DTC) antidepressant advertising did not significantly relate to misperceptions; and (d) DTC exposure magnified misperceptions when consumers were highly trustful of DTC advertising, whereas exposure diluted misperceptions when consumers were highly skeptical. Theoretical and practical implications of the research are discussed, especially in light of the social responsibility of DTC advertising.

    Webb, Densie; Byrd-Bredbenner, Carol

    2015-01-01

    Despite 35 y of dietary guidance, there has been no substantial shift in consumer compliance. Consumers report that they seek information on nutrition and healthy eating, but most are not paying attention to dietary recommendations. For guidance to be effective, it must be realistic. Even with increasingly detailed nutrition information and evidence that diet affects health outcomes, convenience and taste remain the strongest determinants of food choices. It is up to health educators to clear up confusion and give consumers control with nutrition messages that are realistic, positive, easy to understand, and actionable without an expectation that consumers will surrender foods they love.

Four segments were identified: Ethical Consumers (18.09%, Boycotters (20.48%, Ecological Consumers (27.86% and Conventional Consumers (33.57%. The Ethical Consumers’ segment consists of well educated citizens, who adopt all ethical behaviours more frequently. These consumers were found to be more confident they can control politics, less materialists, most attracted by post-materialist goals as well as less sceptical towards ethical products and less indifferent about ethical consumption issues. This segment may be considered as attractive enough to be targeted by business and non for profit organisations.

    Full Text Available This paper tests the applicability of the CSI instrument to measuring consumer decision-making styles in the Croatian environment. The analysis assesses the validity and the reliability of CSI scales and examines gender differences in consumer-decision making styles. Research results point to the existence of eight consumer characteristics and thus validate the applicability of CSI instrument in the Croatian environment. Our findings further indicate that there were gender differences on five factors of consumer-decision making styles (perfectionist, novelty-fashion consciousness, recreational-hedonistic consumer, impulsiveness, habitual shopping behavioral. No significant differences in consumer decision styles between men and women were found with regard to three factors (brand consciousness, price consciousness and confused by overabundant choice. The CSI measurement system may help practitioners to gain a better understanding of how to position their products and services more effectively.

  16. Optimizing the efficacy of multimedia consumer health information.

    Monkman, Helen; Kushniruk, Andre W

    2015-01-01

    Using two or more communication methods (e.g., text, narration, pictures, animation, video) is known as multimedia. Multimedia has been used in a broad range of domains. Not surprisingly, multimedia is gaining popularity in the field of consumer health information as its benefits are being recognized. However, there is a large body of evidence in the cognitive literature that could be used to inform and optimize multimedia presentation of consumer health information. This paper outlines the Cognitive Theory of Multimedia Learning (CTML) and presents the application of this model for consumer health informatics. The CTML is a valuable resource for the development and revision of consumer health information to optimize its efficacy. Current research on multimedia and consumer health information is described. Finally, the outstanding opportunities to leverage the CTML for consumer health information are discussed.

    An informed consumer can compensate for several potential food safety violations or contaminations that may occur earlier in the food production chain. However, a consumer can also destroy the work of others in the chain by poor food handling practices, e.g., by storing chilled ready-to-eat foods at abusive temperatures. To target risk-reducing strategies, consumer groups with high-risk behavior should be identified. The aim of this study was to identify demographic characteristics associated with high-risk food handling practices among Norwegian consumers. More than 2,000 randomly selected Norwegian consumers were surveyed, and the results were analyzed with a risk-based grading system, awarding demerit points for self-reported food safety violations. The violations were categorized into groups, and an ordinary multiple linear regression analysis was run on the summarized demerit score for each group and for the entire survey group as a whole. Young and elderly men were identified as the least informed consumer groups with the most unsafe practices regarding food safety. Single persons reported poorer practices than those in a relationship. People with higher education reported poorer practices than those with lower or no education, and those living in the capital of Norway (Oslo) reported following more unsafe food practices than people living elsewhere in Norway. Men reported poorer food safety practices than women in all categories with two exceptions: parboiling raw vegetables before consumption and knowledge of refrigerator temperature. These findings suggest that risk-reducing measures should target men, and a strategy is needed to change their behavior and attitudes.

    2012-10-01

    Full Text Available Protection of consumers became a phenomenon of many governmental politics. Retrieval of a balance between privat autonomy and protection of a weaker party is very sensitive. The particular degree of consumers protection through limitation of contractual autonomy (in B2C contracts as well as procedural autonomy (regarding B2C dispute resolution mechanisms, as chosen by particular governments, has both legal and economic effects, in positive and negative sense. The European Court of Human Rights adjudicated repeatedly that traditional court litigation is not capable to grant effective protection to contractual claims in many countries. Arbitration is therefore one of possible tools for B2C dispute resolution, even if many countries and obviously the EU Commission followe rather an opposite strategy (keeping down arbitrability of B2C disputes in the opposite to US trends. Arbitration is not a cure-all and definitely not a method suitable for the resolution of any and all types of disputes. It has its proponents as well as opponents. Indeed, it is hard to claim that a particular type (class of disputes is a priori fit to be resolved in arbitration, rather than litigation, or vice versa. This also applies to consumer disputes (disputes from consumer contracts. It is fairly undisputable that consumers deserve a certain degree of specific protection in cases in which they are forced to enter into a particular contract and have no other option than to accept the conditions stipulated by the other party (the professional. But we cannot principally claim that the resolution of these disputes in court would be more suitable than arbitration or any other, the so-called alternative, dispute resolution method (ADR.

    1996-09-01

    When marketing environmentally responsible packaged products, the producer is confronted with consumer beliefs concerning the environmental friendliness of packaging materials. When making environmentally conscious packaging decisions, these consumer beliefs should be taken into account alongside the technical guidelines. Dutch consumer perceptions of the environmental friendliness of packaged products are reported and compared with the results of a life-cycle analysis assessment. It is shown that consumers judge environmental friendliness mainly from material and returnability. Furthermore, the consumer perception of the environmental friendliness of packaging material is based on the postconsumption waste, whereas the environmental effects of production are ignored. From the consumer beliefs concerning environmental friendliness implications are deduced for packaging policy and for environmental policy.KEY WORDS: Consumer behavior; Environment; Food; Packaging; Perception; Waste

A highly trained panel documented appearance, mouthfeel and flavor attributes of 26 commercial soymilks. Twelve representative soymilks were then selected for evaluation by consumers from 3 age/cultural categories (n = 75 each category; Caucasian/African American females aged 18 to 30 y; Asian females aged 18 to 30 y; Caucasian/African American females aged 40 to 64 y). Consumers evaluated overall liking and liking and intensity of specific attributes. Results were evaluated by analysis of variance, followed by internal and external preference mapping. Age had no effect on overall liking, while ethnicity did (Caucasian/African American compared with Asian; P consumer clusters were identified. Sweet taste with vanilla/vanillin and sweet aromatic flavors and higher viscosity were preferred by most consumers and differences between consumer clusters were primarily in drivers of dislike. Drivers of dislike were not identified for Cluster 1 consumers while Clusters 2 and 3 consumers (n = 84, n = 80) disliked beany, green/grassy and meaty/brothy flavors and astringency. Cluster 3 (n = 80) consumers scored all soymilks higher in liking (P consumers, and were willing to overlook disliked attributes with the addition of sweet taste, whereas the Cluster 2 consumers were not. These findings can be utilized to produce soymilks with attributes that are well liked by target consumers and to tailor attributes for segments of the population that have not yet been accommodated. © 2015 Institute of Food Technologists®

    People with serious mental illnesses experience increased rates of physical illnesses. Drop-in centers and psychosocial rehabilitation programs can serve as important settings for health promotion efforts, but such efforts should utilize communication strategies that are used by consumers and are perceived to be reliable. Focus groups involving 23 consumers at drop-in centers in Philadelphia were conducted to assess the perceived usefulness of health information from a variety of sources. Consumers especially liked getting information from other people, including health care professionals, friends, and family, and found the information to be reliable and useful. Print literature, the Internet, and a library had various limitations. Respondents were generally unfamiliar with community health fairs and related events. Consumers considered trustworthiness, proximity and availability, and the specificity and depth of information provided by a communication source when getting health information. Implications for health promotion efforts are discussed.

    Recently, increases in energy prices have made energy conservation and efficiency improvements even more essential than in the past. However, consumers experience difficulty in obtaining reliable information regarding energy efficiency, so that many countries have implemented regulations to enforce energy-efficiency grade labeling. In this study, consumer preferences regarding energy efficiency grades are analyzed by the mixed logit and MDCEV model based on the revealed preference data of past automobile purchases. Findings show that consumers rationally apply information on energy efficiency grades when purchasing automobiles. However, they tend to show inefficiency in automobile usage patterns. This study discusses political implications of energy efficiency policies as they might impact consumer behaviors of automobile purchase and usage. - Highlights: ► We model discrete choice model to evaluate energy-efficiency grade regulation. ► Consumers apply information on energy efficiency grades when purchasing automobiles. ► However, they tend to show inefficiency in automobile usage patterns. ► The policies for efficient automobile usage are discussed.
