Subject:
consumer expenditure surveys; models; prices
Abstract:
... This study evaluates the differences between the Exact Affine Stone Index (EASI) demand model estimates obtained using Consumer Expenditure Survey (CEX) data and Nielsen Homescan data. Results indicated that elasticities obtained from CEX and Homescan data–based demand models differ not only statistically but also economically. Own-price elasticities obtained from the CEX data–based demand model w ...

Abstract:
... A new species, Serpocaulon australe, from the Yungas Montane Forest of Argentina and Bolivia, is described based on a reinterpretation of the name S. gilliesii. The new species is similar to S. lasiopus, but can be distinguished by its rhizome scales with entire margins and acute-acuminate apices, glabrous fronds with few axillary scales in the segments, sori absent in the apex of the segments, an ...

Trillium delicatum sp. nov. differs from the two other low-growing species of the subgenus, T. decumbens and T. reliquum, in features such as straight stems and dung-scented flowers. It occurs in wet floodplain forests in the Oconee and Ocmulgee river drainages in central Geor ...

Abstract:
... The Exact Affine Stone Index (EASI) demand model offers distinct advantages over its predecessors. However, it does not account for pre-committed demand. This can bias elasticity estimates when such pre-commitments are present. We derive a generalized EASI model that allows for pre-committed demand. We illustrate the advantage of this model in an empirical analysis of food demand in Russia using p ...

Hydrological drought as characterized by low river inflow rate (IR), and, in turn, low water level (WL) and greater water residence time (WRT), may support greater algal biomass and blooms in lakes. Lake Diefenbaker (LD), a large mesotrophic reservoir on the Canadian Prairies, receives ∼98% of its inflow from the South Saskatchewan River (SSR). The SSR annual flow volume largely varies with precip ...

Abstract:
... Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is one of the most important diseases of soybean. Disease management is complicated by the long-term survival of sclerotia in the soil and the absence of resistance in elite, commercial cultivars. Furthermore, the lifecycle of S. sclerotiorum in soybean fields is highly dependent on weather conditions, leading to a highly sporadic occ ...

Abstract:
... 1. Plant responses to herbivory are often specific to the feeding guild of the attacking herbivore. These phytochemical responses to herbivore damage can affect herbivore performance and activity. Comprehensive studies on the ecological consequences of multi‐herbivore plant interactions are key to understanding plant–herbivore community dynamics. 2. This study examined how feeding damage by co‐occ ...

Abstract:
... DNA methylation is an important epigenetic modification that governs transcriptional regulation. The methylation mark is read by a special class of proteins called methyl-CpG-binding domain proteins. The role of DNA methylation has been found in X-chromosome inactivation, genomic imprinting, transposon silencing, and self-incompatibility. Recently, remodeling of global DNA methylation was demonstr ...

Genetic analyses have shown that more than 40 autophagy-related genes (ATG) are directly involved in this process in fungi. In addition to Atg proteins, most vesicle transport regulators are also essential for each step of autophagy. The present study showed that one Endopl ...

Abstract:
... The CMBS is an exotic pest of crapemyrtle trees in the United States that decreases aesthetic value through excretion of honeydew and subsequent colonization by sooty mold. The sooty mold can cover the bark if infestation levels are high, causing a concern for landscapers and nursery growers. This efficacy trial was conducted on potted crapemyrtles growing on black nursery cloth outdoors at the Te ...

Abstract:

One way in which resources from the amaranth crop could be exploited as an alternative to grain is to grow amaranth in the dry season, harvest only the leaves, and incorporate them into meals. In this environmental condition, insects associated with the amaranth crop are poorly known. Results showed that Diabrotica balteata L ...
