Behavioral Response of Rhyzopertha dominica, Lesser Grain Borer, to Wheat Volatiles
The lesser grain borer is a grain pest that eats and damages grain products such as rice, corn, wheat, and millet (Edde, 2012). The lesser grain borer has a tendency to to reproduce rapidly and explode into big infestations under optimal conditions, which become hard to control (Johnson, 2000). Controlling these infestations has been moderately successful with the use of pheromones, which attract the beetles (El-Azi, 2011). The purpose of this research is to pinpoint the lesser grain borerâs potential preference of different wheat volatiles it is given, and find the strongest response. The hypothesis is that certain samples that have higher moisture, a stronger odor, or an added pheromone that could elicit the strongest response to the volatiles than samples that do not have these conditions. The results obtained from this research indicate that our hypothesis is fairly correct, showing the aged, wet wheat with an added pheromone had the highest preference among all samples tested. The significance of this research should bring the gap closer between effectively controlling the lesser grain borer and grain safety, which will maximize the product, reduce the potential hazards to human health, and be the framework for other similar problems with grain pests around the worl

Demand for Pasture-Raised Livestock Products: Results from Michigan Retail Surveys
Pasture-raised livestock production offers opportunity for product differentiation and enhanced sustainability. Shopper surveys at three Michigan retail locations measured consumersâ attitudes and beliefs regarding pasture-raised livestock products, and willingness to pay for pasture-raised milk and beef. The shoppers associate pasture-raised products with attributes important to purchase decisions. The shoppers express willingness to pay, on average, about 35% more for pasture-raised milk and beef. Informational messages appear to have no effect on these responses. We suggest pasture-raised is a viable marketing strategy and recommend premium pricing strategies and promotion based on verifiable health benefits.animal welfare, consumer demand, pasture-raised livestock products, sustainability, Tobit, willingness to pay, Agribusiness, Demand and Price Analysis, Livestock Production/Industries,
Demand for Pasture-Raised Livestock Products in Michigan: Results of Consumer Surveys and Experimental Auctions
Pasture-raised livestock products present a niche-marketing opportunity for small- and medium-scale farmers; growth of this market may enhance the economic, social, and environmental sustainability of livestock agriculture. Results from an earlier statewide poll in Michigan found that consumers place great importance on product attributes associated with the pasture-based production model. This report presents findings from a combination of consumer surveys conducted at three Michigan retail locations and a series of experimental auctions. Participants in both the survey and auction components view pasture-raised beef and milk products very favorably, believing these products are healthy for humans to eat and are raised in environmentally friendly and humane ways. Survey respondents reported high likelihood of purchase; both the survey and auction subjects expressed willingness to pay a premium for pasture-raised products. We discuss these findings, particularly implications for the ââŹĹfour Pâsâ⏠of marketing.Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,
Consumer Preferences for Organic and Fair Trade Chocolate: Implications for Sustainable Agriculture in the Developing World
This paper examines results of a consumer survey measuring consumer awareness and attitudes concerning two labels, certified organic and certified Fair Trade. These labels provide information about the social, economic and environmental sustainability of the production and marketing practices of goods imported from the developing world. Conjoint analysis is used to measure how consumers value organic and fair trade compared to other attributes like price. Results indicate favorable attitudes and value placed on these the sustainable attributes, and imply a role for these labels to provide incentives for the adoption of more sustainable practices.conjoint analysis, Fair Trade, organic, Food Consumption/Nutrition/Food Safety,
THE ORGANIC LABEL: HOW TO RECONCILE ITS MEANING WITH CONSUMER PREFERENCES
The USDA's National Organic Program (NOP), with its unified definition and labeling requirements, holds great promise for increasing commerce in and decreasing transaction costs associated with purchasing organic food. However, the label and its meaning must both be well understood and reflect the traits consumers want if this promise is to be realized. This paper reports the results of a survey and experimental auction on consumers' preferences for organic standards. On one hand, the USDA NOP's Final Rule broadly conforms to consumer preferences regarding what practices should or should not be permitted in organic production and processing. Consumers support a strict definition of organic in general, opposing the use of a variety of practices historically banned by organic certifiers. For example, both the survey and auction methods found that consumers support the banning of Genetically Modified Organisms in organic food and are willing to pay a premium to avoid them. Consumers are also in accord with the Final Rule's exclusion of irradiation, biosolids, growth regulators, etc. On the other hand, the survey and auction results reveal a lack of understanding of the label's meaning as well as a disconnect between the label's function (detailing acceptable production practices) and consumers' stated motivations for buying organic (e.g., support for a local sustainable food system). Implications of these findings for decision makers in policy and industry are discussed. Of particular focus will be the role of these agents in promoting products that allow consumers to purchase items that reflect and support these values.Consumer/Household Economics,

Community Supported Agriculture Pricing and Promotion Strategies: Lessons from Two Ithaca, NY, Area Farms
E.B. 2003-07Surveyed members of two Community Supported Agriculture (CSA) farms in the Ithaca (Tompkins County) NY area state that the qualities they value most in their CSA share are freshness, organically grown and local. These members place the least amount of importance on the price, season length, and sense of community. In addition, the price paid for a share in each CSA was less than a consumer would have to pay for the same bundle of goods at three local retail outlets, especially if the consumer took advantage of âpick your ownâ specials on the farm. CSA (sometimes called âsubscription farmingâ) is an arrangement under which members pay a fee at or near the beginning of the season to cover farm expenses, in return for a share of the farmâs harvest throughout the season. At least 80 CSA farms are active in New York State, according to the Robyn VanEn Center for CSA Resources. At least ten serve the Tompkins County area alone (Cornell Cooperative Extension -Tompkins County). Members share the risks of crop failure and provide working capital to the growers and in some cases are required to contribute labor (sometimes in exchange for a lower price), but gain the satisfaction of connecting with the land and growers, knowing where the food comes from and participating in the production of their food (DeMuth). Members and producers often share basic ideologies (Lass et al.). CSAs offer other benefits to consumers, producers and society as a whole. They can build bridges between farmers and non-farmers on the urban/rural fringe (Sharp et 2 al.). They educate people about the food system (Lass et al.; Sharp et al.) and have a larger role in community building in rural areas (Sharp et al.). CSAs have little or no food spoilage, compared to up to 25% on conventional farms (Lass et al.). CSAs are also believed to play a role in stabilizing food security, protecting the environment and preserving small scale family farms (Stagl and OâHara). The goals of this study were twofold: (1) to compare prices of CSA shares from two Ithaca area farms with equivalent prices for the same produce items from local retail outlets; and (2), to measure membersâ attitudes about and satisfaction with CSA membership. Results will guide promotional and pricing strategies for these and other CSA farms, as well as other farms involved in direct marketing. Price and promotion are identified as two vital components of the marketing strategy for products (like CSA shares) in the introductory or growth phases of the product life cycle (Kotler)
Effects of Second Language Learning on Mental Representations of Time
The following thesis is a domain-centered study that examines the effects of second language (L2) learning on mental representations of time in native English learners of L2 Mandarin Chinese. The design of this study attempts to observe the effects of the existence and use of spatiotemporal metaphors in Mandarin Chinese on L2 learners of the language. The methodology used for data collection includes a three-dimensional pointing paradigmâa partially language-independent taskâwhich attempts to isolate cognitive behavior. The task requires participants to answer questions (by pointing) regarding space and time on imaginary axes in front of their person using their own fist as the reference point in their answer; this precludes any language effects caused by having to use language in completing experimental tasks. The participants of the study include advanced L2 learners of Mandarin Chinese as the focus experimental group and English native speakers as the control group. Results confirm the hypothesis that learning a second language does influence speakersâ mental representations of time; while English native speakers significantly preferred the transverse axis in virtually all cases, L2 Mandarin learners displayed a preference for both the transverse and sagittal axes, without significantly distinguishing between the two. This study adds to previous literature in the field, providing evidence in support of the linguistic relativity theory
Dissociation Across the Lifespan
Dissociation is a disorder in which people separate themselves from the thoughts associated with traumatic events they have experienced. People can experience dissociative symptoms across the entire developmental lifespan. Traumatic events that produce high levels of PTSD symptomatology can also contribute to the development of a dissociative disorder, especially if the individual experiences dissociative symptoms during the traumatic event. However, high levels of dissociative symptoms has more of an influence on the development of PTSD than PTSD does on the development of dissociative symptoms. Trauma is strongly correlated with the development of dissociative symptoms. A dissociative subtype of PTSD was added to the DSM-V and is expected to account for 10% of all PTSD cases. The chances of developing a dissociative disorder increase if an individual experienced early childhood abuse and neglect. Studies of the elderly who have experienced dissociative symptoms suggest that the passage of time may act as a buffer and a means by which the severity of dissociative symptoms are lessened. Using an individualized approach by gathering specific information from people who suffer from dissociation informs caregivers as to whether confronting trauma directly through journaling or speaking expressively about their trauma is appropriate
