Consumer science: a science for sustainability
Authors: Sibbel Anne 
Published: October 2010

Consumers are essentially decision‐makers, with a strong influence in the product chain. Establishing sustainable global resource systems, across developed and developing nations, is dependent on finding ways to encourage consumers to prioritise environmental issues as one of the key determinants of their consumption decisions. More than this, all stakeholders in the product chain must become aware of their impacts on the psychological, social, cultural, physical and economic environments that predispose consumers to certain approaches when making consumption decisions.Conventional science has not provided the solutions for several reasons. Pure science and technology have developed according to different agendas and interests. Science has generally not been communicated in ways that allow consumers to make day‐to‐day decisions, fully informed of the implications. The barriers to genuine interdisciplinary research required to generate socially relevant solutions to the complex problems associated with traditional consumption patterns are only now being slowly overcome.Due to its interdisciplinary and integrated nature, consumer science provides a theoretical platform from which to formulate the core questions, articulated within a framework in which all stakeholders can contribute in synergistic ways to reverse the escalating rates of resource depletion, disparities of resources between groups, loss of species and pervasive pollution. There is no other discipline which offers an encompassing and integrated framework for the responsible communication of science necessary to describe the problems. Most importantly, consumer science has the capacity to research and interpret individual and social behaviour in ways which lead to innovative and effective controls to improve and sustain new standards for living on this vulnerable plant.
The golden age of protein: initial teacher trainee's perception of food and eating
Authors: Lakin Liz 
Published: October 2010

We make use of proteins in all aspects of our daily lives from soft‐centred sweets to biological washing powders, yet we often misunderstand their fundamental role in our diet.This paper will draw on the findings of a three‐phase research project into initial teacher trainee's perception of food and eating. Trainees demonstrated several similar misconceptions about the food they eat and in particular, the role of proteins. Examples included the role of proteins as an energy source, the relationship between proteins, amino acids and nitrogen and the role of DNA in synthesising proteins. These misconceptions were often translated into practice in the diet the trainees consumed and the messages they passed on, with confidence, to their pupils. In addition to the misconceptions, teaching approaches used by the trainees were highly mechanistic, with little reference being given to the relationship between food and the circumstances in which it is eaten.The relationship between dietary intake and exercise/circumstance is explored in secondary schools within food technology lessons. Often, however, it is too late to rectify the deeply entrenched misconceptions, attitudes and eating habits that school children have developed in their primary years. This paper makes the firm recommendation that we should reconsider the dietary messages we are sending out either directly or indirectly, to children. It emphasises the need to relate teaching and learning to everyday experiences. The paper concludes by suggesting possible strategies by which this may be achieved, with the protein featuring centre‐stage.

AbstractThis paper reports the findings of a consumer‐driven investigation conducted by the Centre for Clinical Nursing Research at Epworth Hospital in conjunction with the Endometriosis Association (Victoria, Australia) aimed at identifying the information and support needs of women experiencing endometriosis. Women's experiences of endometriosis and laparoscopy were examined. A questionnaire was designed to explore women's experiences of, and informational need for, the four categories of: diagnosis of endometriosis, endometriosis, laparoscopy and managing at home. A total of 465 women who had a positive diagnosis of endometriosis, including patients at the Epworth Endometriosis Centre and members of the Endometriosis Association, were included. The data were analysed in terms of frequency of responses and themes that arose from the research. Five main themes consistently emerged from the overall analysis of the questionnaire; these included: lack of communication, no‐one listens, the emotional turmoil, expressions of gratitude to the Endometriosis Association and being young and helpless. Also identified was a lack of understanding of endometriosis and laparoscopy, on behalf of both the patient and the practitioner, which has led to communication of misinformation, extended physical pain and emotional distress. Based on these findings, recommendations were made for education strategies to be focused towards increasing awareness of endometriosis and for information to be disseminated using the preferred printed format and to be made available from gynaecologists, hospitals and schools. Through consumer participation, the information obtained in this study is of benefit to all women who come in contact with endometriosis by (a) validating women's experiences of endometriosis and (b) identifying women's needs in relation to the disease.
Effect of arbuscular mycorrhizal (AM) colonization on terpene emission and content of Artemisia annua L.
Authors: Rapparini F. , Llusià J. , Peñuelas J. 
Published: October 2010

AbstractPlant roots interact with a wide variety of rhizospheric microorganisms, including bacteria and the symbiontic arbuscular mycorrhizal (AM) fungi. The mycorrhizal symbiosis represents a series of complex feedbacks between plant and fungus regulated by their physiology and nutrition. Despite the widespread distribution and ecological significance of AM symbiosis, little is known about the potential of AM fungi to affect plant VOC metabolism. The purpose of this study was to investigate whether colonization of plant roots by AM fungi and associated soil microorganisms affects VOC emission and content of Artemisia annua L. plants (Asteraceae). Two inoculum types were evaluated: one consisted of only an arbuscular mycorrhizal (AM) fungus species (Glomus spp.), and the other was a mixture of different Glomus species and associated soil bacteria. Inoculated plants were compared with non‐inoculated plants and with plants supplemented with extra phosphorus (P) to obtain plants of the same size as mycorrhizal plants, thus excluding potentially‐confounding mycorrhizal effects on shoot growth. VOC emissions of Artemisia annua plants were analyzed by leaf cuvette sampling followed by off‐line measurements with pre‐concentration and gas chromatography mass spectrometry (GC‐MS). Measurements of CO2 and H2O exchanges were conducted simultaneously. Several volatile monoterpenes were identified and characterized from leaf emissions of Artemisia annua L. by GC‐MS analysis. The main components identified belong to different monoterpene structures: α‐pinene, β‐pinene, camphor, 1,8‐cineole, limonene, and artemisia ketone. A good correlation between monoterpene leaf concentration and leaf emission was found. Leaf extracts included also several sesquiterpenes. Total terpene content and emission was not affected by AM inoculation with or without bacteria, while emission of limonene and artemisia ketone was stimulated by this treatment. No differences were found among treatments for single monoterpene content, while accumulation of specific sesquiterpenes in leaves was altered in mycorrhizal plants compared to control plants. Growth conditions seemed to have mainly contributed to the outcome of the symbiosis and influenced the magnitude of the plant response. These results highlight the importance of considering the below‐ground interaction between plant and soil for estimating VOC emission rates and their ecological role at multitrophic levels.
Importance of representing optical depth variability for estimates of global line-shaped contrail radiative forcing
Authors: Kärcher Bernd , Burkhardt Ulrike , Ponater Michael , Frömming Christine 
Published: October 2010

Estimates of the global radiative forcing by line-shaped contrails differ mainly due to the large uncertainty in contrail optical depth. Most contrails are optically thin so that their radiative forcing is roughly proportional to their optical depth and increases with contrail coverage. In recent assessments, the best estimate of mean contrail radiative forcing was significantly reduced, because global climate model simulations pointed at lower optical depth values than earlier studies. We revise these estimates by comparing the probability distribution of contrail optical depth diagnosed with a climate model with the distribution derived from a microphysical, cloud-scale model constrained by satellite observations over the United States. By assuming that the optical depth distribution from the cloud model is more realistic than that from the climate model, and by taking the difference between the observed and simulated optical depth over the United States as globally representative, we quantify uncertainties in the climate model’s diagnostic contrail parameterization. Revising the climate model results accordingly increases the global mean radiative forcing estimate for line-shaped contrails by a factor of 3.3, from 3.5 mW/m

to 11.6 mW/m

for the year 1992. Furthermore, the satellite observations and the cloud model point at higher global mean optical depth of detectable contrails than often assumed in radiative transfer (off-line) studies. Therefore, we correct estimates of contrail radiative forcing from off-line studies as well. We suggest that the global net radiative forcing of line-shaped persistent contrails is in the range 8–20 mW/m

For nearly 100 million years, the India subcontinent drifted from Gondwana until its collision with Asia some 50 Ma, during which time the landmass presumably evolved a highly endemic biota. Recent excavations of rich outcrops of 50–52-million-year-old amber with diverse inclusions from the Cambay Shale of Gujarat, western India address this issue. Cambay amber occurs in lignitic and muddy sediments concentrated by near-shore chenier systems; its chemistry and the anatomy of associated fossil wood indicates a definitive source of Dipterocarpaceae. The amber is very partially polymerized and readily dissolves in organic solvents, thus allowing extraction of whole insects whose cuticle retains microscopic fidelity. Fourteen orders and more than 55 families and 100 species of arthropod inclusions have been discovered thus far, which have affinities to taxa from the Eocene of northern Europe, to the Recent of Australasia, and the Miocene to Recent of tropical America. Thus, India just prior to or immediately following contact shows little biological insularity. A significant diversity of eusocial insects are fossilized, including corbiculate bees, rhinotermitid termites, and modern subfamilies of ants (Formicidae), groups that apparently radiated during the contemporaneous Early Eocene Climatic Optimum or just prior to it during the Paleocene-Eocene Thermal Maximum. Cambay amber preserves a uniquely diverse and early biota of a modern-type of broad-leaf tropical forest, revealing 50 Ma of stasis and change in biological communities of the dipterocarp primary forests that dominate southeastern Asia today.
Productivity Orientation and the Consumption of Collectable Experiences
Authors: Keinan Anat , Kivetz Ran 
Published: October 2010

Abstract
This research examines why consumers desire unusual and novel consumption experiences and voluntarily choose leisure activities, vacations, and celebrations that are predicted to be less pleasurable. For example, consumers sometimes choose to stay at freezing ice hotels and to eat at restaurants serving peculiar foods, such as bacon ice cream. We propose that such choices are driven by consumers' continual striving to use time productively, make progress, and reach accomplishments (i.e., a productivity orientation). We argue that choices of collectable (unusual, novel, extreme) experiences lead consumers to feel productive even when they are engaging in leisure activities as they “check off” items on an “experiential check list” and build their “experiential CV.” A series of laboratory and field studies shows that the consumption of collectable experiences is driven and intensified by a (chronic or situational) productivity orientation.
Development of a Benchtop Baking Method for Chemically Leavened Crackers. I. Identification of a Diagnostic Formula and Procedure
Authors: Kweon Meera , Slade Louise , Levine Harry 
Published: October 2010

ABSTRACTA benchtop baking method has been developed to predict the contribution of gluten functionality to overall flour performance for chemically leavened crackers. To identify a diagnostic cracker formula, the effects of leavening system (sodium bicarbonate, monocalcium phosphate, and ammonium bicarbonate), sugar concentration (%S), and total solvent (TS) on cracker‐baking performance were explored. From preliminary experiments to establish a production procedure, 10 min of dough‐mixing time, a cord‐weave baking mesh, and a 500°F oven temperature were selected. For the leavening system, increasing ammonium bicarbonate (ABC) level at constant sodium bicarbonate (soda) and monocalcium phosphate (MCP) levels resulted in increased cracker height. For the diagnostic formula, 1.25 g of soda, 1.25 g of MCP, and 1.25 g of ABC were selected, based on 100 g of flour. As the sugar concentration in the cracker formula, at constant total solvent (38 TS), decreased to <20%, the resulting cracker dough became softer, and the baked cracker exhibited an increased blistering tendency because of a too‐high formula water level. In contrast, a cracker dough formulated with >40% sugar concentration was too crumbly to handle and sheet. As the total solvent in the cracker formula increased at constant sugar concentration (≈23.7%S), the resulting dough became softer. A dough with 34 TS was too crumbly to handle, while doughs with 42 and 46 TS were too soft to handle and resulted in blistering. Therefore, 38 TS and 23.7%S were identified for the diagnostic formula. Crackers baked with a hard wheat flour, a soft wheat flour, and blends validated the utility of the developed method.

ABSTRACTDough extensibility affects processing ease, gas retention, and loaf volume of finished products. The Kieffer dough extensibility test was developed to assess extensibility of small dough samples and is therefore adapted for use in breeding programs. Information is lacking on relationships between wheat growing environments and dough properties measured by the Kieffer dough extensibility test. This study documents the variability of dough extensibility (Ext), maximum resistance to extension (Rmax), and area under the extensibility curve (Area) in relation to breadmaking quality, and the effect of wheat growing environments. Mixograph, Kieffer dough extensibility, and bake tests were performed on flour milled from 19 hard red spring wheat (Triticum aestivum L.) genotypes grown during three growing seasons (2007‐2009) at six South Dakota locations. Although both genotype and environment had significant effects on Kieffer dough extensibility variables, environment represented the largest source of variation. Among genotype means, Area was most correlated (r = 0.63) with loaf volume, suggesting that by selecting lines with increased Area, loaf volume should improve. Rmax was positively correlated (r = 0.58) with loaf volume among genotype means but negatively correlated (r = –0.80) among environmental means. Ext was positively correlated (r = 0.90) with loaf volume among environmental means. Weather variables were correlated with Rmax, Ext and loaf volume and therefore could help predict end‐use quality.

Published: October 2010

ABSTRACTFlour was obtained from oats fermented with lactic acid bacteria (LAB) to study the effect of fermentation on the physical properties and the suitability of fermented oats for use in starch noodle production. The results showed that fermented samples had a significantly lower pH than control samples. Gel strength and amylose content initially increased and then decreased (P < 0.05) with fermentation time. The peak viscosity, breakdown, final viscosity, and setback value decreased with fermentation time. Fermented noodles showed a higher hardness and springiness. In particular, Lactobacillus plantarum (LP) induced the highest springiness, cohesiveness, gumminess, chewiness, and resilience over 12 hr of fermentation. The cooking quality evaluation indicated that fermentation improved the quality of oat starch noodles. Fermented oats resulted in noodles with low cooking loss and higher cooking weight compared to noodles made from fresh flour. The use of LP for 12 hr of fermentation time yielded noodles of the best quality.
First Report of Oidium longipes as the Causal Agent of Petunia Powdery Mildew in the United Kingdom
Authors: Kiss L. , Bereczky Z. 
Published: October 2010

In autumn 2009, during a survey of powdery mildews of solanaceous plants in the United Kingdom, petunia (Petunia × hybrida) plants showing typical symptoms of powdery mildew infections were repeatedly collected in East Malling, Rochester, and Sandringham, UK. Leaves, stems, and petals of the collected plants, grown as outdoor ornamentals, were covered by dense, sporulating, white mycelium. Conidia were ellipsoid-cylindrical, measured 20 to 30 × 10 to 15 μm, and were produced in chains. Germ tubes arose from the ends of conidia and terminated in simple, unlobed apices. Some of the conidiophores were extremely long, up to 250 μm, because the second or third cell, or sometimes the foot cell, was up to 105 to 170 μm long. Other conidiophores were shorter, with no exceptionally long cells, but all of them exhibited a few characteristics in common: their width increased from base to top, sometimes enlarging considerably at a particular point of the foot cell, and basal septa were usually located 7 to 30 μm from the point of branching. Hyphal appressoria were nipple shaped. The teleomorph stage was not found. On the basis of these characteristics, the fungus was identified as Oidium longipes, a recently described (4) and little known pathogen of petunia and other solanaceous plants (1,3). To support the identification of this fungus, DNA was extracted from conidia collected with sterile brushes from single leaves collected in Sandringham, East Malling, and Rochester with a Qiagen DNeasy Plant Kit (Qiagen, Hilden, Germany), and the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA was amplified and determined as described in Jankovics et al. (2). The three identical ITS sequences, deposited in GenBank under Accession Nos. HM156495, HM156496, and HM156497, were identical to several ITS sequences of O. longipes, such as AF250777, EU327324, and EU327325. This has also supported that the disease was caused by this species. Herbarium specimens were deposited under the Accession Nos. HAL 2373F, HAL 2374F, and HAL 2375F at the Herbarium of Martin Luther University, Halle, Germany. To our knowledge, this is the first report of O. longipes in the UK. References: (1) A. Bolay.

ABSTRACTAims  This study conducted a secondary analysis to examine injection cessation and decreasing frequency of injection during a multi‐site randomized controlled HIV prevention intervention trial that sought to reduce sexual and injection risk behavior among young injection drug users.Design and Setting  A six‐session, cognitive–behavioral skills‐building intervention in which participants were taught peer education skills [peer education intervention (PEI)] was compared with a time‐equivalent attention control. Follow‐up interviews were conducted at 3 and 6 months post‐baseline.Participants  Trial participants were HIV and hepatitis C virus (HCV) antibody‐negative injection drug users aged 15–30 years. Participants who had at least one follow‐up interview and reported injecting drugs in the previous 3 months at baseline were eligible for the present analysis (n = 690).Measurements  At each interview, data were collected on the number of times participants injected drugs over the previous 3 months.Findings  Twenty‐seven per cent of participants reported at least one 3‐month period of injection cessation. In a multivariate, zero‐inflated negative binomial regression adjusting for prior injection frequency, time of follow‐up and psychosocial variables, PEI trial arm and smaller session size were associated significantly with injection cessation. Trial arm had no effect on the frequency of injection among those who continued to inject.Conclusions  HIV prevention interventions that encourage injection drug users to take on the role of peer educator may have the additional benefit of increasing the likelihood of injection cessation. Intervention group size is also an important consideration, with smaller groups having higher rates of cessation.
