State Implementation of the New WIC Produce Package: Opportunities and Barriers for WIC Clients to Use Their Benefits at Farmers' Markets
The new WIC fruit and vegetable package will create a $500 million market annually for produce. Even if 10% of these benefits were spent at farmers markets, it would provide a big boon for access to local food and to small farmers. This report discovers that half of the states are shutting farmers markets out of this potentially lucrative market, and looks at the reasons why

Having a people : beyond individualism and essentialism in resistance to interlocked oppressions.
This dissertation draws on the Aristotelian and contemporary communitarian belief that humans are socially constituted, and analyzes the manifestations of this belief in contemporary identity politics and in the concept of \u27culture\u27 that often underlies identity politics. While I argue that it is important to maintain a communitarian conception of the self, I depart from Aristotle and the communitarian tradition by rejecting the assumption that a constitutive community is characterized by unity and homogeneity. I then claim that identity politics has inherited both the virtues and the problems of communitarian theory. Just as communitarians claim that the self is never free from social constitution, so identity politics have taken the self\u27s identity to be formed along lines of socially defined group differences, and like communitarianism, some identity politics has entailed a call for unity. In the case of identity politics, the requirement for membership in the community may be sharing certain essential characteristics of identity; difference can result in marginalization, forced assimilation to the group norm, or expulsion. Because identity politics often relies upon the concept of \u27culture\u27 to ground group identities, I also examine this concept. When a community\u27s unity derives from its members understanding themselves to share a culture, the maintenance of the culture itself can be conservatizing; the culture can remain closed off from changes as it preserves the traditional or authentic ; furthermore, it can come to be treated as an object outside of the people who live it and as such the changing lived realities of these people--particularly changes that cross lines of identity--do not serve to continually offer new, changing, and ambiguous ways of conceiving of what is shared between members of the community. I argue for the development of group identity that recognizes intersecting group differences, and can permit hybridity or mixed identities. I end by suggesting that for a constitutive community to remain truly constitutive without harming its members through marginalization, forced assimilation to a norm or a shared essence, or stagnation, members must give up the sort of control that maintains the community as a unity

Time Evolution of the Neel State
A quasionedimentional spin chain (s=1/2) is considered as a lattice
consisting of two sublattices. The attention is paid to the states which are
pure spin states of the whole lattice and both sublattices, the value of the
sublattices' spins being maximum. It is shown that the Neel state can be
considered as a superposition of such states. The exact equation for this
superposition coefficients is developed.
The possibility of the Neel state to be the eigenstate of a Hamiltonian is
discussed. Several model Hamiltonians are examined, the well known ones and few
novel Hamiltonians being considered. The time evolution of the Neel state in
different models is studied with the help of Fock-Krylov method.Comment: 10 pages, 5 figures. Submitted to IJQC. Typos corrected. Some results

Moral Failure — Response to Critics
I briefly introduce Moral Failure as a book that brings together philosophical and empirical work in moral psychology to examine moral requirements that are non-negotiable and that contravene the principle that “ought implies can.” I respond to Rivera by arguing that the process of construction that imbues normative requirements with authority need not systematize or eliminate conflicts between normative requirements. My response to Schwartzman clarifies what is problematic about nonideal theorizing that limits itself to offering action-guidance. In response to Kittay, I defend my rejection of “ought implies can,” and consider the implications of the concept of unfair moral requirements
Critical Temperature Tc and Charging Energy Ec between B-B layers of Superconducting diboride materials MgB2 in 3D JJA model
The diboride materials MB2 (M = Mg, Be, Pb, etc.) are discussed on the basis
of the 3D Josephson junction array (JJA) model due to Kawabata-Shenoy-Bishop,
in terms of the B-B layers in the diborides analogous to the Cu-O ones in the
cuprates.
We propose a possibility of superconducting materials with the MgB2-type
structure which exhibit higher critical temperature Tc over 39K of MgB2.
We point out a role of interstitial ionic atoms (e.g., Mg in MgB2) as
capacitors between the B-B layers, which reduce the charging coupling energy in
JJA.Comment: 3 pages, 1 figure included; to be published in J. Phys. Soc. Jpn. 70,

The Role of Mitochondrial ATP-Binding Cassette Transporter ABCB6 in Metabolism and Energy Balance
Abstract Obesity and the associated health risks represent a world-wide health and financial crisis. Lack of physical activity combined with excessive caloric intake are the root cause of the problem. Despite the increased advocation for healthy lifestyle choices, the trend has yet to reverse and indeed, seems to be on the rise especially among pre-teens and adolescents, a constituent that had not been previously part of the obesity epidemic. Mitochondria are the “fuel-burners” of the body and like other combustion devices, become inefficient in the context of fuel surplus. Moreover, with chronic over-feeding, the physiological mechanisms that regulate energy balance become permanently dysfunctional leading to the progression of pathologies such as Type II diabetes and cardiovascular disease. Medical and scientific evidence confirms that mitochondria are integral to the responses necessary to adapt to over-nutrition. However, success in mitochondria-based therapies has been extremely limited in the context of metabolic diseases. Our knowledge of the regulation of mitochondrial function, dynamics, signaling, and transport processes in different tissues and organ systems is extremely limited and this knowledge gap is a serious impediment to progress toward targeting mitochondria for treatment of metabolic diseases. In this study, we successfully genetically manipulated the expression of mitochondrial transporter ABCB6. The physiological function of this transporter is unknown but non-functional mutations of this protein have been linked to several heritable human diseases. This study establishes that ABCB6 plays a role in the maintenance of energy homeostasis. Whole-body Abcb6 knockout adult male and female mice have increased body mass with no increases in food consumption. Increased body mass is due to increased adiposity. ABCB6 deficiency results in steatosis, glucose intolerance, insulin resistance, and lower energy expenditure. Exposure to high-fat diet exacerbates these metabolic derangements. Genetically targeting ABCB6 expression specifically in liver results in disruption of whole-body energy metabolism as well with a loss of metabolic flexibility. Loss of hepatic ABCB6 results in fragmented mitochondria while overexpression leads to mitochondrial elongation, dysregulating dynamic mitochondrial functional responses to energy status. In this liver-specific model, hepatic metabolites are significantly altered with either ABCB6 knockdown or overexpression. Metabolites that have a profound impact on energy metabolism such as bile acids, amino acids, and phospholipids were significantly altered in this model. Interestingly, we discovered that ABCB6 expression is responsive to nutrient status and circadian patterns. ABCB6 expression is upregulated in the fasted state and rapidly downregulated in response to feeding. Also, ABCB6 expression is reduced in cases of chronic over-nutrition such as, diet and genetic mouse models of obesity as well as in clinically obese humans. These findings suggest that ABCB6 acts as a nutrient sensor and mediates a homeostatic response through dynamic mitochondrial changes in form and function
The elementary guidance counselor: An essential part of elementary education
Education is a social process. Human interaction is the single most important ingredient in education. Most human behaviors are learned. They develop as a consequence of persons interacting with their environment. The type of person we are is determined by the interactions we have with other human beings. When teaching a child, educators must interact with the total individual; this has become known as teaching the total child . Education can no longer deal singly with the teaching of subject content, as has been the practice in the past. This method has not produced adults who are prepared to meet the challenges of society. Young people need to be armed with decision-making and problem-solving· skills to function in the complex adult world. Due to the problems facing children today, some children feel like failures before they leave the elementary school
