SHOPPING FOR MEAT: EMPIRICAL DEMAND ESTIMATION FOR NATURAL BEEF ACROSS STORE CHOICES

Conventional supermarkets concentrate on capturing the largest pool of consumers to generate profits from the industry's low margins. Selling to the largest pool of customers means that marketing, promotion, stocking and service decisions are based on the tastes and preferences of an average consumer. Innovators in the grocery industry, recognizing a shift in consumer tastes and preferences, are changing the industry to attract smaller segments of consumers. The theory presented here demonstrates a method to understand the value of product diversification and a model of the gains from providing products that may not have broad appeal to the average customer base. The increase in retail returns through this approach of developing in-store niches lies not in increased single-item purchases of any one consumer, but through the increased number of items purchased (a larger bundle) by an individual on a single shopping trip.Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,

Ontogenetic Patterns of Agonistic Behavior in a Guild of Larval Ambystomatid Salamanders

Agonistic behavior is a common feature of larval amphibians inhabiting temporary ponds. Given the temporally staggered sequence of hatching by pond-breeding amphibians, ontogenetic patterns of aggression can influence coexistence if larvae of certain species or ages are subject to increased aggression. To determine whether aggression changes through larval ontogeny, we observed agonistic behavior of Ambystoma opacum, Ambystoma tigrinum, and Ambystoma maculatum at four stages of development spanning the larval period. We tracked aggression rates among individual larvae to determine whether previous success, in the form of increased aggression, facilitated success in subsequent contests. All species exhibited distinct ontogenetic patterns of aggression, with the highest and lowest rates of aggression exhibited during rear leg development and metamorphosis, respectively. Species-specific aggression rates were observed, with A. tigrinum consistently displaying the highest levels of aggression. Winner or loser effects were not evident, because increased aggression early in the larval period did not result in increased aggression throughout ontogeny. We hypothesize that the observed patterns of behavior may represent a baseline level of aggression upon which other biotic and abiotic factors act in mediating coexistence among larval amphibians

Strategic use of nickel(0)-catalyzed enyne–epoxide reductive coupling toward the synthesis of (−)-cyatha-3,12-diene

Various situations are explored in which the nickel(0)-catalyzed enyne–epoxide reductive coupling was utilized to access key intermediates toward the total synthesis of (−)-cyatha-3,12-diene (1). Enantioenriched 3,5-dien-1-ols with a variety of functionality were obtained in a straightforward manner from easily accessible 1,3-enynes and terminal epoxides.National Institute of General Medical Sciences (U.S.) (GM-063755)Massachusetts Institute of Technology.

The Null Decomposition of Conformal Algebras

We analyze the decomposition of the enveloping algebra of the conformal algebra in arbitrary dimension with respect to the mass-squared operator. It emerges that the subalgebra that commutes with the mass-squared is generated by its Poincare subalgebra together with a vector operator. The special cases of the conformal algebras of two and three dimensions are described in detail, including the construction of their Casimir operators.Comment: 31 page

A Lagrangian View of Stratospheric Trace Gas Distributions

As a result of photochemistry, some relationship between the stratospheric age-of-air and the amount of tracer contained within an air sample is expected. The existence of such a relationship allows inferences about transport history to be made from observations of chemical tracers. This paper lays down the conceptual foundations for the relationship between age and tracer amount, developed within a Lagrangian framework. In general, the photochemical loss depends not only on the age of the parcel but also on its path. We show that under the "average path approximation" that the path variations are less important than parcel age. The average path approximation then allows us to develop a formal relationship between the age spectrum and the tracer spectrum. Using the relation between the tracer and age spectra, tracer-tracer correlations can be interpreted as resulting from mixing which connects parts of the single path photochemistry curve, which is formed purely from the action of photochemistry on an irreducible parcel. This geometric interpretation of mixing gives rise to constraints on trace gas correlations, and explains why some observations are do not fall on rapid mixing curves. This effect is seen in the ATMOS observations

Depression among women of reproductive age in rural Bangladesh is linked to food security, diets and nutrition

Objective: To quantify the relationship between screening positive for depression and several indicators of the food and nutrition environment in Bangladesh.Design: We used cross-sectional data from the Food and Agricultural Approaches to Reducing Malnutrition (FAARM) trial in Bangladesh to examine the association of depression in non-peripartum (NPW) and peripartum women (PW) with food and nutrition security using multivariable logistic regression and dominance analysis.Setting: Rural north-eastern Bangladesh.Participants: Women of reproductive age.Results: Of 2599 women, 40 % were pregnant or up to 1 year postpartum, while 60 % were not peripartum. Overall, 20 % of women screened positive for major depression. In the dominance analysis, indicators of food and nutrition security were among the strongest explanatory factors of depression. Food insecurity (HFIAS) and poor household food consumption (FCS) were associated with more than double the odds of depression (HFIAS: NPW OR = 2·74 and PW OR = 3·22; FCS: NPW OR = 2·38 and PW OR = 2·44). Low dietary diversity (<5 food groups) was associated with approximately double the odds of depression in NPW (OR = 1·80) and PW (OR = 1·99). Consumption of dairy, eggs, fish, vitamin A-rich and vitamin C-rich foods was associated with reduced odds of depression. Anaemia was not associated with depression. Low BMI (<18·5 kg/m2) was also associated with depression (NPW: OR = 1·40).Conclusions: Depression among women in Bangladesh was associated with many aspects of food and nutrition security, also after controlling for socio-economic factors. Further investigation into the direction of causality and interventions to improve diets and reduce depression among women in low-and middle-income countries are urgently needed. © © The Authors 2020
