Impact Of Remittance On Food Security In Bangladesh, Madhav Regmi, Krishna P. Paudel

Faculty Publications

© 2016 by Emerald Group Publishing Limited All rights reserved. Purpose - The purpose of this chapter is to assess the food security situation in Bangladesh based on 2011/2012 Bangladesh Integrated Household Survey data using two commonly measured food security indicators: Food Consumption Score (FCS) and Household Hunger Scale (HHS). Methodology/approach - The dependent variable in the model is a categorical variable representing different scales of food security as obtained from the FCS and HHS indicators. These categorical variables are explained by annual remittances received by the households; the demographic characteristics (age, gender, literacy level, and occupation) of the household …

International Intellectual Property Shelters, Sam F. Halabi

Faculty Publications

The battle over the reach and strength of international protections for intellectual property rights is one of the critical flashpoints between wealthy and low-income countries: those protections are perceived to obstruct access to essential medicines, thwart regulatory efforts to promote individual and population health, and undermine traditional forms of agriculture and food production. While scholars have thoroughly tracked the bilateral and multilateral trade and investment treaties responsible for the expansion of international intellectual property rights worldwide, they have paid significantly less attention to the strength and form that opposition to international intellectual property expansion has taken. This Article examines the …

A Member Of The Phosphate Transporter 1 (Pht1) Family From The Arsenic-Hyperaccumulating Fern Pteris Vittata Is A High-Affinity Arsenate Transporter, Sandra Feuer Ditusa, Elena B. Fontenot, Robert W. Wallace, Molly A. Silvers, Thomas N. Steele, Alia H. Elnagar, Kelsey M. Dearman, Aaron P. Smith

Faculty Publications

© 2015 New Phytologist Trust. Pteris vittata exhibits enhanced arsenic uptake, but the corresponding mechanisms are not well known. The prevalent form of arsenic in most soils is arsenate, which is a phosphate analog and a substrate for Phosphate transporter 1 (Pht1) transporters. Herein we identify and characterize three P. vittata Pht1 transporters. Pteris vittata Pht1 cDNAs were isolated and characterized via heterologous expression in Saccharomyces cerevisiae (yeast) and Nicotiana benthamiana leaves. Expression of the PvPht1 loci in P. vittata gametophytes was also examined in response to phosphate deficiency and arsenate exposure. Expression of each of the PvPht1 cDNAs complemented …

Pteridine Levels And Head Weights Are Correlated With Age And Colony Task In The Honey Bee, Apis Mellifera, Frank D. Rinkevich, Joseph W. Margotta, Jean M. Pittman, James A. Ottea, Kristen B. Healy

Faculty Publications

Background. The age of an insect strongly influences many aspects of behavior and reproduction. The interaction of age and behavior is epitomized in the temporal polyethism of honey bees in which young adult bees perform nurse and maintenance duties within the colony, while older bees forage for nectar and pollen. Task transition is dynamic and driven by colony needs. However, an abundance of precocious foragers or overage nurses may have detrimental effects on the colony. Additionally, honey bee age affects insecticide sensitivity. Therefore, determining the age of a set of individual honey bees would be an important measurement of colony …

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodríguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Faculty Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …

Cryopreservation In Fish: Current Status And Pathways To Quality Assurance And Quality Control In Repository Development, Leticia Torres, E. Hu, Terrence R. Tiersch

Faculty Publications

Cryopreservation in aquatic species in general has been constrained to research activities for more than 60 years. Although the need for application and commercialisation pathways has become clear, the lack of comprehensive quality assurance and quality control programs has impeded the progress of the field, delaying the establishment of germplasm repositories and commercial-scale applications. In this review we focus on the opportunities for standardisation in the practices involved in the four main stages of the cryopreservation process: (1) source, housing and conditioning of fish; (2) sample collection and preparation; (3) freezing and cryogenic storage of samples; and (4) egg collection …

Microbial Mat Communities Along An Oxygen Gradient In A Perennially Ice-Covered Antarctic Lake, Anne D. Jungblut, Ian Hawes, Tyler J. Mackey, Megan Krusor, Peter T. Doran, Dawn Y. Sumner, Jonathan A. Eisen, Colin Hillman, Alexander K. Goroncy

Faculty Publications

© 2016, American Society for Microbiology. Lake Fryxell is a perennially ice-covered lake in the McMurdo Dry Valleys, Antarctica, with a sharp oxycline in a water column that is density stabilized by a gradient in salt concentration. Dissolved oxygen falls from 20 mg liter-1 to undetectable over one vertical meter from 8.9-to 9.9-m depth. We provide the first description of the benthic mat community that falls within this oxygen gradient on the sloping floor of the lake, using a combination of micro- and macroscopic morphological descriptions, pigment analysis, and 16S rRNA gene bacterial community analysis. Our work focused on three …

Do Vertebral Chemical Signatures Distinguish Juvenile Blacktip Shark (Carcharhinus Limbatus) Nursery Regions In The Northern Gulf Of Mexico?, Justin P. Lewis, William F. Patterson Iii, John K. Carlson, Katherine Mclachlin

Faculty Publications

Identifying and protecting shark nurseries is a common management strategy used to help rebuild overfished stocks, yet we know little about connectivity between juvenile and adult populations. By analysing trace metals incorporated into vertebral cartilage, it may be possible to infer natal origin based on nursery-specific chemical signatures. To assess the efficacy of this approach, we collected juvenile blacktip sharks (Carcharhinus limbatus; n = 93) from four regions in the Gulf of Mexico in 2012 and 2013 and analysed their vertebral centra with laser ablation-inductively coupled plasma-mass spectrometry. We observed significant regional differences in six element : Ca …

The Maternal Personhood Of Cattle And Plants At A Hindu Center In The United States, Daniel S. Capper

Faculty Publications

Religious experiences with sacred nonhuman natural beings considered to be “persons” remain only vaguely understood. This essay provides a measure of clarification by engendering a dialogue between psychoanalytic self psychology on one side and, on the other, religious experiences of cattle and Tulsi plants as holy mothers at a Hindu cattle sanctuary in the United States. Ethnographic data from the Hindu center uncover experiences of sacred maternal natural beings that are tensive, liminal, and colored with affective themes of nurturance, respect, and intimacy, much like psychoanalytic maternal selfobjects. Devotees protect cattle and ritually venerate plants because these actions facilitate a …

Groundhog Oracles And Their Forebears, Daniel S. Capper

Faculty Publications

Groundhog Day animal weather forecasting ceremonies continue to proliferate around the United States despite a lack of public confidence in the oracles. This essay probes religio-historical and original ethnographic perspectives to offer a psychological argument for why these ceremonies exist. Employing Paul Shepard’s notion of a felt loss of sacred, intimate relationships with nonhuman nature, as well as Peter Homans’ concept of the monument that enables mourning, this essay argues that groundhog oracles serve as monuments that allow humans experientially to attempt to heal lost sacred relationships with animals like weather forecasting bears, hedgehogs, and badgers

Gras-Fed Americans: Sick Of Lax Regulation Of Food Additives, Martha Dragich

Faculty Publications

Americans are “GRAS-fed” because of a “loophole” in the strict regime Congress provided for the regulation of food additives. Additives - and food products containing them - are exempt from this strict regime if they are accorded GRAS (Generally Recognized as Safe) status. The guidelines Congress provided for achieving that status by scientific evidence of safety are no longer observed. Most additives are determined by the producer alone to be GRAS. At the same time, Americans’ consumption of highly processed foods continues to rise, giving rise to long-term health problems that are increasingly tied to diet. The average American’s diet …

Assessing Alternative Techniques For Scaling The Family Leisure Activity Profile: Recommendations For Future Family Leisure Measurement, Karen K. Melton, Gary Ellis, Ramon Zabriskie

Faculty Publications

Psychometric properties of the Family Leisure Activity Profile (FLAP) were evaluated using family leisure and family functioning ratings from 884 parents and children residing in the United Kingdom. Review and critique of the FLAP resulted in identification and evaluation of three alternative scaling techniques. Scaling Technique 1was current practice, Technique 2 focused on family leisure environments rather than family leisure activities, and Technique 3 involved generating an estimate of duration of participation in family leisure in natural units of time. Inter-rater agreement and reliability were strong for all three scaling techniques. Technique 3 yielded the best model fit. Empirical relations …

Persistent Threats To Commercial Speech, Jonathan H. Adler

Faculty Publications

The current Supreme Court is very protective of speech, including commercial speech. Threats to commercial speech persist nonetheless. This article briefly examines two: the use of commercial speech restrictions as a form of rent-seeking, and compelled commercial speech. Regulation of commercial speech is sometimes used to protect established corporate interests from competitors who are less able to bear the costs of regulation, with consequences that extend beyond the economic marketplace. In the case of commercial speech, courts have also been unduly deferential to claims of a consumer “right to know” as a basis for mandated labeling and disclosure. Greater and …

Compelled Commercial Speech And The Consumer "Right To Know", Jonathan H. Adler

Faculty Publications

Compelled commercial speech, including mandatory labeling and the disclosure of factually true information, should not be seen as a separate category of speech under the First Amendment. Rather, compelled commercial speech should be understood as a type of commercial speech and be subject to the same level of protection as commercial speech generally. Accordingly, commercial speech compulsions, such as mandatory disclosures and labeling requirements, must be supported by a substantial government interest under the Central Hudson framework. The assertion of a consumer “right to know” does not constitute such an interest and cannot, by itself, justify compelled commercial speech within …

Pro-Fit: Exercise With Friends, Saumil Dharia, Vijesh Jain, Jvalant Patel, Jainikkumar Vora, Rizen Yamauchi, Magdalini Eirinaki, Iraklis Varlamis

Faculty Publications

The advancements in wearable technology, where embedded accelerometers, gyroscopes and other sensors enable the users to actively monitor their activity have made it easier for individuals to pursue a healthy lifestyle. However, most of the existing applications expect continuous commitment from the end users, who need to proactively interact with the application in order to connect with friends and attain their goals. These applications fail to engage and motivate users who have busy schedules, or are not as committed and self-motivated. In this work, we present PRO-Fit, a personalized fitness assistant application that employs machine learning and recommendation algorithms in …

No Association Between Current Depression And Latent Toxoplasmosis In Adults, Bruce L. Brown, Shawn D. Gale, Andrew N. Berrett, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Changes in behaviour and cognition have been associated with latent infection from the apicomplexan protozoan Toxoplasma gondii (Nicolle et Manceaux, 1908) in both animal and human studies. Further, neuropsychiatric disorders such as schizophrenia have also been associated with latent toxoplasmosis. Previously, we found no association between T. gondii immunoglobulin G antibody (IgG) seropositivity and depression in human adults between the ages of 20 and 39 years (n = 1 846) in a sample representative of the United States collected by the Centers for Disease Control as part of a National Health and Nutrition Examination Survey (NHANES) from three datasets collected …

Methods: We used the National Health and Nutrition Exami-nation Survey (NHANES) datasets to examine whether folate concentrationor inflammation mediates or moderates the relationship betweenH. pyloriand cognitive function. Models were performed using linear, Poisson, andzero-inflated Poisson regression, and we performed separate analyses forgroups aged 20–59 and 60–90 years with sample sizes ranging from 700 to1700.Results:We did not find evidence of mediation in either age group. In the20- to 59-year group, interactions betweenH. pyloriand ferritin (pvaluesranging from .004 to …

No Association Between Latent Toxoplasmosis And Multiple Body Measures In U.S. Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (Nicolle et Manceaux, 1908) is an intracellular parasite that can cause ongoing latent infection persisting for the duration of a non-definitive host's life. Affecting approximately one-third of the world's population, latent toxoplasmosis has been associated with neuropsychological outcomes and a previous report suggested an association between latent toxoplasmosis and adult height. Given the large number of people with latent toxoplasmosis and its potential associations with human height, we sought to better understand the association between latent toxoplasmosis and human morphology by evaluating seropositivity for T. gondii and multiple body measures reported in the National Health and Nutrition Examination …

Solutions For Wellness: Outcome Review And Analysis Of A Healthy Lifestyle Group, Gary Burlingame, Valerie King, Rebecca Janis

Faculty Publications

Individuals with serious mental illness (SMI) experience a notably decreased life span due, in part to a metabolic syndrome linked to psychotropic medications commonly prescribed to SMI patients. Eli Lilly’s Solutions for Wellness (SFW) program was designed to address some of the risk factors (e.g., weight, diet, lifestyle) that exacerbate the metabolic syndrome in SMI outpatients. However, there is limited data as to the effectiveness of the SFW program for hospitalized SMI patients. We replicate and compare SFW outcomes from an inpatient SMI population treated at the Utah State Hospital with previous research that tested an abbreviated SFW curriculum of …

Breeding Technologies In U.S. Meat Goat Production: Who Are The Adopters And How Does Adoption Impact Productivity?, Jeffrey Gillespie, Berdikul Qushim, Narayan Nyaupane, Kenneth Mcmillin

Faculty Publications

Copyright 2015 Northeastern Agricultural and Resource Economics Association. Adoption of advanced breeding technologies and management practices (BTMP) in U.S. meat goat production and their impact were examined. Adopters generally had larger-scale operations, used rotational grazing and/or dry lot systems, and sold larger percentages of animals for breeding and show purposes. Farmer demographics and farm variables also influenced adoption. Complementarity of adoption was found-adopters of one BTMP tended to adopt other BTMPs. Measures of productivity and profitability were not affected by adoption. Goat breed, farmer experience, production system used, and specialization influenced productivity, and farm size had the greatest influence on …

Successive 1-Month Weight Increments In Infancy Can Be Used To Screen For Faltering Linear Growth, Adelheid W. Onyango, Elaine Borghi, Mercedes De Onis, Edward A. Frongillo Jr., Cesar G. Victora, Kathryn G. Dewey, Anna Lartey, Nita Bhandari, Anne Baerug, Cutberto Garza

Faculty Publications

Background: Linear growth faltering in the first 2 y contributes greatly to a high stunting burden, and prevention is hampered by the limited capacity in primary health care for timely screening and intervention.

Objective: This study aimed to determine an approach to predicting long-term stunting from consecutive 1-mo weight increments in the first year of life.

Methods: By using the reference sample of the WHO velocity standards, the analysis explored patterns of consecutive monthly weight increments among healthy infants. Four candidate screening thresholds of successive increments that could predict stunting were considered, and one was selected for …

Novel Mode Of Defective Neural Tube Closure In The Non-Obese Diabetic (Nod) Mouse Strain, J. Michael Salbaum, Claudia Kruger, Jacalyn Macgowan, Nils J. Herion, David Burk, Claudia Kappen

Faculty Publications

Failure to close the neural tube results in birth defects, with severity ranging from spina bifida to lethal anencephaly. Few genetic risk factors for neural tube defects are known in humans, highlighting the critical role of environmental risk factors, such as maternal diabetes. Yet, it is not well understood how altered maternal metabolism interferes with embryonic development, and with neurulation in particular. We present evidence from two independent mouse models of diabetic pregnancy that identifies impaired migration of nascent mesodermal cells in the primitive streak as the morphogenetic basis underlying the pathogenesis of neural tube defects. We conclude that perturbed …

Rural School Food Service Director Perceptions On Voluntary School Meal Reforms, Disa Lubker Cornish, Natoshia Askelson, Elizabeth Golembiewski

Faculty Publications

This mixed-method study examined rural U.S. food service directors' perceptions of and experiences with voluntary school meal programs, which have the potential to improve school nutrition but have not been widely adopted in rural areas of the United States. Little is known about how rural food service directors perceive these programs. Interview and survey instruments examined how rural food service directors characterize barriers and facilitators to participation in voluntary school meal programs like farm-to-school and school garden programs. Rural school food service directors participated in a semistructured telephone interview (n=67) and an online survey (n=57). We defined rural school districts …

Experiences With Food Insecurity And Risky Sex Among Low-Income People Living With Hiv/Aids In A Resource-Rich Setting, Henry J. Whittle, Kartika Palar, Tessa Napoles, Lee Lemus Hufstedler, Irene Ching, Frederick M. Hecht, Edward A. Frongillo Jr., Sheri D. Weiser

Faculty Publications

Background: Forty-nine million individuals are food insecure in the United States, where food insecurity and HIV/AIDS are prevalent among the urban poor. Food insecurity is associated with risky sexual behaviours among people living with HIV/AIDS (PLHIV). No qualitative studies, however, have investigated the mechanisms underlying this relationship either in a resource-rich setting or among populations that include men who have sex with men (MSM).

Methods: Semi-structured in-depth interviews were conducted with 34 low-income PLHIV receiving food assistance in the San Francisco Bay Area. The interviews explored experiences with food insecurity and perceived associations with sexual risk behaviours. Interviews were conducted …

Fetal Programming In Meat Production, Min Du, Bo Wang, Xing Fu, Qiyuan Yang, Mei Jun Zhu

Faculty Publications

© 2015 Elsevier Ltd. Nutrient fluctuations during the fetal stage affects fetal development, which has long-term impacts on the production efficiency and quality of meat. During the early development, a pool of mesenchymal progenitor cells proliferate and then diverge into either myogenic or adipogenic/fibrogenic lineages. Myogenic progenitor cells further develop into muscle fibers and satellite cells, while adipogenic/fibrogenic lineage cells develop into adipocytes, fibroblasts and resident fibro-adipogenic progenitor cells. Enhancing the proliferation and myogenic commitment of progenitor cells during fetal development enhances muscle growth and lean production in offspring. On the other hand, promoting the adipogenic differentiation of adipogenic/fibrogenic progenitor …
