title: Ci-TCF Gene Function and Its Involvement in Ciona intestinalis Pigment Cell Differentiation
Creators: name: Parveen, Fateema
Publisher: name: The Open University
Year: 2010

description: Transcription factors of T cell factor (TCF) family have been identified in a wide range of organisms, from hydra to mammals, where they play important roles during embryonic development. As a terminal nuclear component they mediate the canonical Wnt signaling cascade by their context dependent transcriptional regulatory properties. The TCF protein family in Ciona intestinalis is represented by a single member, named Ci-TCF, whose zygotic expression has been observed in pigment precursor cells as well as in palp precursors. Ascidians occupy a strategic position in the phylogeny and thus provide a useful model system to study developmental processes difficult to approach in more complex organisms.

I aimed to better clarify the role played by Ci-TCF specifically in pigment cell differentiation in Ciona. To this end I exploited targeted interference with Ci-TCF function. I used an enhancer specific for pigment cell lineage to drive the expression of a dominant negative form of Ci-TCF. From this study it was possible to deduce that Ci-TCF is effectively involved in the terminal differentiation of pigment cells in sensory organs.

Simultaneously, my project was also focused on the regulatory factors controlling the precise spatio-temporal activation of Ciona TCF gene in pigment lineage. Analysis of the cis-regulatory region of Ci-TCF gene was performed through a series of constructs containing various Ci-TCF 5’ promoter fragments fused to a reporter gene. This study allowed me to characterize a region of 400 bp in Ci-TCF enhancer element which was able to drive reporter gene expression in pigment cells of Ciona. In silico analysis of this cis-regulatory region revealed the possible involvement of Ets transcription factors governing the tissue specific expression of Ci-TCF at the right time. The data was further confirmed by detailed in vivo and in vitro studies, through mutational assay and EMSA (Electrophoretic mobility shift assay), respectively. My study therefore led to the identification of Ets factors as the first upstream regulator of a TCF representative. Since Ets transcription factors are activated via MAP kinase pathway which is triggered by FGF signaling, the present study provides clues for a crosstalk between the Wnt and FGF signaling cascades during pigment cell differentiation in Ciona intestinalis. This finding is noteworthy, since up to now all the data on TCFs have concerned their function as effectors of Wnt signaling. No explanations have been reported so far as to why and how TCF factors are present at the right time and in the right place to play their role downstream from Wnt. So, my study gives a first answer to this question and represents a first step toward a better understanding of the regulation of TCF’s expression.
The dynamical evolution of fractal star clusters: the survival of substructure

description: We simulate the dynamics of fractal star clusters, in order to investigate the evolution of substructure in recently formed clusters. The velocity dispersion is found to be the key parameter determining the survival of substructure. In clusters with a low initial velocity dispersion, the ensuing collapse of the cluster tends to erase substructure, although some substructure may persist beyond the collapse phase. In clusters with virial ratios of 0.5 or higher, initial density substructure survives for several crossing times, in virtually all cases. Even an initially homogeneous cluster can develop substructure, if it is born with coherent velocity dispersion. These results suggest that the simple initial conditions used for many sophisticated $N$-body simulations could be missing a very important and dramatic phase of star cluster evolution.

description: The pace of change and development of new technology in the new millennium necessitates fast and efficient data accumulation, processing, interpretation and dissemination to maintain a competitive advantage in any information orientated field. With regards to primary data accumulation, if academic institutions stick to rigid traditional tools and not embrace changes in the information/communications revolution they will face the criticism of further irrelevancy. Traditional academic surveys are also one of the most expensive components of any research project budget. Communication technology advancements, such as electronic mail (e-mail), the Internet and Cellular phone technology such as SMS (Short Messaging Service) and WAP (Wireless Application Protocol), create an opportunity to drastically reduce survey costs and time. The use of e-mail as a potential electronic medium for conducting a survey is discussed in this paper. E-mail was chosen because of the minimal costs involved and the specific market that can be targeted. It does, however, have its own problems and limitations. The key question asked in the e-survey was: "What do South African farmers need to do to survive, and better yet: prosper, in the new millennium?" The focus of this paper is not the answers to this question, but on the methodology, shortfalls, profile of respondents, reply statistics and some netiquette tips used in thee-survey.

description: The speeches stated by influential politicians can have a decisive impact on the future of a country. In particular, the economic content of such speeches affects the economy of countries and their financial markets. For this reason, we examine a novel dataset containing the economic content of 951 speeches stated by 45 US Presidents from George Washington (April 1789) to Donald Trump (February 2017). In doing so, we use an economic glossary carried out by means of text mining techniques. The goal of our study is to examine the structure of significant interconnections within a network obtained from the economic content of presidential speeches. In such a network, nodes are represented by talks and links by values of cosine similarity, the latter computed using the occurrences of the economic terms in the speeches. The resulting network displays a peculiar structure made up of a core (i.e. a set of highly central and densely connected nodes) and a periphery (i.e. a set of non-central and sparsely connected nodes). The presence of different economic dictionaries employed by the Presidents characterize the core-periphery structure. The Presidents' talks belonging to the network's core share the usage of generic (non-technical) economic locutions like "interest" or "trade". While the use of more technical and less frequent terms characterizes the periphery (e.g. "yield" ). Furthermore, the speeches close in time share a common economic dictionary. These results together with the economics glossary usages during the US periods of boom and crisis provide unique insights on the economic content relationships among Presidents' speeches.

description: Structural, magnetic and ferromagnetic resonance characterization studies have been performed on lay-ered ferromagnetic-ferroelectric oxides that show strong magnetoelectric coupling. The samples contained thick films of ferrites or substituted lanthanum manganites for the ferromagnetic phase and lead zirconate titanate for the ferroelectric phase, and were sintered high temperatures. Results indicate defect free ferrites, but deterioration of manganite parameters due to diffusion at the interface and accounts for poor magnetoelectric coupling in manganite-PZT samples.

title: Emerging Writing Practices in Post-Compulsory Secondary Education: An Investigation Into the 'Review' Task of the Certificate of Personal Effectiveness (CoPE)
Creators: name: Baker, Sally
Publisher: name: The Open University
Year: 2009

description: Pressure to address the perceived skills shortage of school and university leavers has resulted in a greater focus on developing and assessing personal skills in post-compulsory education, such as Personal Development Planning (PDP) in higher education. As a consequence, 'new' forms of writing and assessment are emerging alongside more traditional genres, which is arguably causing tension and confusion for students and teachers as they adapt to these new ways of writing. This project addresses this tension by examining a specific case of 'emerging writing', the 'review' form from the Certificate of Personal Effectiveness (CoPE) in a secondary school sixth form, within an Academic Literacies framework and is positioned within the context of the transition between school and university. This project examines what the CoPE review looks like and explores students' and teachers' perceptions and understandings of it. The findings show that students and teachers have unclear and varied interpretations of what the function of CoPE 'review' is, how it 'should look' and where it fits in the spectrum of genres regularly practised in secondary education. These reactions suggest a lack of understanding of how to approach this 'new' way of writing and, therefore, provides poor training for the 'reflective writing' that is required in PDP in higher education.
title: Tetracycline and its Analogues as Drugs Against Protein Aggregation and Amyloid Formation
Creators: name: Beeg, Marten
Publisher: name: The Open University
Year: 2010

description: With more than 20 million cases worldwide, Alzheimer’s disease (AD) is now the most common neurodegenerative disease. The two defining features of this disease are extracellular plaques and intracellular neurofibrillary tangles. Although no AD treatment is available, researchers are making encouraging progress, including the use of small compounds which interact with amyloid-β (AB) and affect its self aggregation. Tetracyclines (TCs) are thought to have an anti-amyloidogenic effect on Aβ peptides. But the inconsistency of results in literature prompted us to further investigate the behaviour of various fragments of Aβ (Aβ1-40; Aβ1-42; guest-host-peptide Aβ 14-24) which were synthesised as depsi-peptides, in the presence of TCs. Due to their superior solubility the depsi-peptides allowed us to prepare reliable and seed-free stock solutions with reproducible properties. These allowed the preparation of different well-characterised Aβ1-42 species (initial state, oligomers, and fibrils), and to investigate the binding of Aβ ligands (Aβ monomers or TCs) to them or to study the modulation of the kinetics of fibril formation in the absence or presence of TCs, by Surface Plasmon Resonance (SPR), Circular Dichroism (CD) or Thioflavine-T (ThT) fluorescence. Binding of Aβ1-42 monomers to immobilised fibrils could be well described by the “Dock and Lock” mechanism. TCs do not bind to the prepared Aβ species nor do they alter the highly reproducible kinetics of fibril formation or disaggregated preformed amyloidogenic structures. Consistent with the inactivity of TCs against amyloid β-sheet structures the treatment of APP/PS1tg mice with doxycycline (DC) after plaque formation did not change the plaque load in this mouse model compared to the control mice. These findings suggest that toxic Ap species other than these considered in this study or the common neuroprotection seen for TCs might be responsible for the positive effects in-vivo in previously reported studies.

 Diplosoma velatum Kott, 2001: 345 and synonymy.
 Distribution. New records: Western Australia (Oyster Harbour, Albany, WAM 138.93), South Australia (Kangaroo I., SAM E2857, E2910, E2921), Victoria (Bass Strait, QM G12743–4). Previously recorded (see Kott, 2001): Western Australia (Albany, Esperance), South Australia (York Peninsula, Eyre Peninsula, Spencer Gulf, Investigator Strait), Victoria (Western Port).
 Description. One of the newly recorded colonies (SAM E2910) is about 5 cm diameter with a deep, cup-shaped concavity basally (probably once enveloping a rounded pebble) and the upper convex surface raised into intertwining serpentine rounded ridges containing a core of the basal test, and with zooids opening all around the outer surface; another (QM G12744) has cylindrical, finger-like or irregular lobes projecting from the upper surface of the basal mat-like part of the colony. The other newly recorded colonies are the usual fleshy, encrusting masses previously reported for the species. Always, the zooids are clumped together in groups of about 20, each clump attached to the central or basal test by a broad connective. The vast common cloacal cavity penetrates around the thoraces. The test is soft, translucent and the whole colony is cream. Zooids are as previously described with the large branchial sac exposed directly to the common cloacal cavity and two testis follicles. Embryos are crowded in the central or basal test of specimens collected in September (WAM 138.93) and May (SAM E2910). The almost spherical larval trunk is about 1.0 mm long. An oozooid and thoracic and abdominal buds, and four pairs of lateral ampullae are present and the sensory vesicle projects up from the oozooid into the larval test. The tail is relatively short, being wound only halfway around the trunk. Irregular opaque bodies are in the larval test around the oozooid and blastozooid.
 Remarks. The raised surface ridges and projecting lobes have not been described previously for this species. Superficially such colonies look like Trididemnum spp. (e.g. T. nobile) and some Didemnum psammatode in which the lobes appear to overgrow the surface, although in the present species the surface ridges may not have developed in the same way.
 Zooids lack the black squamous epithelium of D. listerianum.

description: Large (> 100 mm$^3$), relatively pure (type II) and low birefringence single crystal diamond can be produced by high pressure high temperature (HPHT) synthesis. In this study we examine a HPHT sample of good crystalline perfection, containing less than 1 ppb (part per billion carbon atoms) of boron impurity atoms in the {001} growth sector and only tens of ppb of nitrogen impurity atoms. It is shown that the boundaries between {111} and {113} growth sectors are decorated by negatively charged nitrogen vacancy centres (NV$^-$): no decoration is observed at any other type of growth sector interface. This decoration can be used to calculated the relative {111} and {113} growth rates. The bulk (001) sector contains concentrations of luminescent point defects (excited with 488 and 532 nm wavelengths) below 10$^{11}$ cm$^{-3}$ (10$^{-3}$ ppb). We observe the negatively charged silicon-vacancy (SiV$^-$) defect in the bulk {111} sectors along with a zero phonon line emission associated with a nickel defect at 884 nm (1.40 eV). No preferential orientation is seen for either NV$^-$ or SiV$^-$ defects, but the nickel related defect is oriented with its trigonal axis along the <111> sector growth direction. Since the NV$^-$ defect is expected to readily re-orientate at HPHT diamond growth temperatures, no preferential orientation is expected for this defect but the lack of preferential orientation of SiV$^-$ in {111} sectors is not explained.

The equations are invariant under duality transformation between the gravitational electric (M) and magnetic (l) charge, radial and angular coordinate, and radial and angular component of the field. We solve the equations separating into radial and angular parts. Moreover, if sets of Klein-Gordan and Dirac equation and corresponding solutions are known for Kerr space-time, under duality transformation, those in dual Kerr space-time are shown to be achieved. A few examples of solution are shown. We comment about the horizon and singularity conditions.

description: Here we start from a dual version of Vasiliev's first order action for massless spin-2 particles (linearized first order Einstein-Hilbert) and derive, via Kaluza-Klein dimensional reduction from $D+1$ to $D$ dimensions, a set of dual massive spin-2 models. This set includes the massive "BR" model, a spin-2 analogue of the spin-1 Cremmer-Scherk model. In our approach the linearized Riemann curvature emerges from a solution of a functional constraint. In $D=2+1$ the BR model can be written as a linearized version of a new bimetric model for massive gravitons. We also have a new massive spin-2 model, in arbitrary dimensions, invariant under linearized diffeomorphisms. It is given in terms of a non symmetric rank-2 tensor and a mixed symmetry tensor.

title: Drug Use in Outpatient Children: Epidemiological Evaluations
Creators: name: Clavenna, Antonio
Publisher: name: The Open University
Year: 2010

description: Background: Pharmacoepidemiology can be a useful tool for evaluating the appropriateness of drug prescriptions and for estimating therapeutic needs. In particular, pharmacoepidemiology can be valuable in the paediatric setting, which is characterized by the availability of only limited information on the safety and effectiveness of drug use.

Methods: Data collected in regional and multiregional administrative prescription databases were analysed. Prevalence data by sex and age were calculated by dividing the number of drug users by the total number of male and female residents in each age group. The number of packages of medications (boxes) was used as indicator of drug consumption. Univariate and multivariate analyses were performed with the aim to identify the determinants of drug prescriptions.

Results: Drug utilization studies reported quantitative and qualitative differences between countries in drug prescription to children and adolescents. In particular, Italian children have a threefold greater chance of receiving an antibiotic or an anti-asthmatic compared with children living in the Netherlands.

Large differences also were found within Italy between different geographical settings, with prevalence ranging between 57.3% in northern Italy and 68.3% in southern Italy. Prevalence varied also between the local health units (LHUs) of a single region and between district of a single LHU. In the Lombardy Region prevalence ranged between 38.4% in Milan and 54.8% in Brescia, and the residence of the child was one of the main determinant of drug exposure.

Conclusions: The studies described in this thesis suggest that pharmacoepidemiology is a valuable tool for monitoring the appropriateness of drug prescribing. However, the epidemiological evaluation of drug prescriptions in children should be improved with regards to the methodological quality of studies.

description: We investigate the expected gravitational wave emission from coalescing supermassive black hole (SMBH) binaries resulting from mergers of their host galaxies. When galaxies merge, the SMBHs in the host galaxies sink to the center of the new merged galaxy and form a binary system. We employ a semi-analytic model of galaxy and quasar formation based on the hierarchical clustering scenario to estimate the amplitude of the expected stochastic gravitational wave background owing to inspiraling SMBH binaries and bursts owing to the SMBH binary coalescence events. We find that the characteristic strain amplitude of the background radiation is $h_c(f) \sim 10^{-16} (f/1 μ{\rm Hz})^{-2/3}$ for $f \lesssim 1 μ{\rm Hz}$ just below the detection limit from measurements of the pulsar timing provided that SMBHs coalesce simultaneously when host galaxies merge. The main contribution to the total strain amplitude of the background radiation comes from SMBH coalescence events at $0

description: Following the European Commission’s concept of a “Knowledge-based Bioeconomy” (KBBE), great significance in the process of political decision-making shall be attached to scientific expertise. In contrast, the conducted print media analysis on the German biofuel discourse for the period from 1995 to 2012 only found a marginal role of scientific actors in the debate. Even though support for biofuels has been largely rejected as inefficient by several scientific brain trusts for many years, the German government, as well as the EU adhere to this policy. This raises the question of the underlying interests that drive the persistent support for biofuels. In this context, the paper investigates the standing and positioning of different actors in the public media and thereby it contributes to a better understanding of why the political support for biofuels is continued, despite the doubts of scientists. One of the core findings of the study states, that one reason for this political support can be seen in the dominance of a coalition of biofuel advocates, mainly formed by political and economic actors, in the public discourse. Laut dem Konzept der Europäischen Kommission einer wissensbasierten Bioökonomie soll dem wissenschaftlichen Expertenwissen eine bedeutende Rolle im politischen Entscheidungsprozess zukommen. Hingegen stellt die durchgeführte Printmedienanalyse des deutschen Biokraftstoffdiskurses von 1995 bis 2012 nur eine untergeordnete Rolle wissenschaftlicher Akteure in der Debatte fest. Obwohl weite Teile der Biokraftstoffförderung seit Jahren von wissenschaftlichen Expertengremien als ineffizient abgelehnt werden, halten die Bundesregierung und die EU an dieser Politik fest. Dies wirft die Frage auf, welche Interessen die anhaltende Förderung von Biokraftstoffen tatsächlich vorantreiben. In diesem Zusammenhang untersucht der Artikel das Standing und die Positionierung verschiedener Akteure in den öffentlichen Medien und trägt damit zu einem besseren Verständnis bei, warum die Biokraftstoffpolitik trotz der starken Kritik von Wissenschaftlern gefördert wird. Ein zentrales Ergebnis der Studie besagt, dass die Dominanz einer Koalition aus Biokraftstoffbefürwortern im öffentlichen Diskurs, welche sich vor allem aus politischen und ökonomischen Akteuren zusammensetzt, als ein Grund für die politische Förderung von Biokraftstoffen anzusehen ist.

description: Noise, commonly defined as an unwanted sound, is an environmental phenomenon to which human are exposed throughout their life. Noise can also be considered an environmental pollutant. Noise is not simply an annoyance rather a hazard to one’s physical and mental well-being. This study attempts to assess the traffic induced noise and suggests some mitigation measures which are likely to reduce the level of noise. The main sources of higher noise level in Rajshahi city due to transportation activities. For this purpose present study was carried out at 10 different important locations with Sound Level Meter to assess the sound level in Rajshahi city. Along with the noise level measurement the traffic volume was also determined at the same time to establish whether any relationship or not. In this study more acute zones which are affected by the sound pollution in Rajshahi city were identified. From the study, it is observed that the maximum noise levels were detected to be 103.5 dB, 105.2 dB, 104.1 dB, 102 dB, 102 dB, 95.5 dB, 99 dB, 99.4 dB, 95.8 dB, 93.8 dB at Talaimari more, Vodra more, Rail station, Rail gate, Kashiadanga, C & B more, Laxmipur more, Monichottor, Saheb Bazer zero point and Alupotti more, respectively. However, more acute zone of Rajshahi city are Bhodra more, Rail station, Talaimari more, Rail gate and Kashiadanga more where noise level is above 100 dB. The study could show any clear relationship between noise level and traffic volume rather it depends upon the whistling of vehicles. These zones are mostly traffic intensive and having always public crowd. The inter district buses are mainly standing in these points to collect passengers and whistling frequently. The study suggested that whistling of the vehicles must be restricted within the city during the collection of passengers.

description: Using density-functional theory we assess the stability of bulk and surface oxides of the late 4d transition metals in a ``constrained equilibrium'' with a gas phase formed of O2 and CO. While the stability range of the most stable bulk oxide extends for ruthenium well into gas phase conditions representative of technological CO oxidation catalysis, this is progressively less so for the 4d metals to its right in the periodic system. Surface oxides could nevertheless still be stable under such conditions. These thermodynamic considerations are discussed in the light of recent experiments, emphasizing the role of (surface) oxides as the active phase of model catalysts formed from these metals.

description: We review recent advances in the capabilities of the open source ab initio Quantum Monte Carlo (QMC) package QMCPACK and the workflow tool Nexus used for greater efficiency and reproducibility. The auxiliary field QMC (AFQMC) implementation has been greatly expanded to include k-point symmetries, tensor-hypercontraction, and accelerated graphical processing unit (GPU) support. These scaling and memory reductions greatly increase the number of orbitals that can practically be included in AFQMC calculations, increasing accuracy. Advances in real space methods include techniques for accurate computation of band gaps and for systematically improving the nodal surface of ground state wavefunctions. Results of these calculations can be used to validate application of more approximate electronic structure methods including GW and density functional based techniques. To provide an improved foundation for these calculations we utilize a new set of correlation-consistent effective core potentials (pseudopotentials) that are more accurate than previous sets; these can also be applied in quantum-chemical and other many-body applications, not only QMC. These advances increase the efficiency, accuracy, and range of properties that can be studied in both molecules and materials with QMC and QMCPACK.

description: We study gravitational lensing by a Reissner-Nordstrom (RN) black hole in the weak field limit. We obtain the basic equations for the deflection angle and time delay and find analytical expressions for the positions and amplifications of the primary and secondary images. Due to a net positive charge, the separation between images increases, but no change in the total magnification occurs.

 Remarks. Oswaldella elongata is an uncommon species, well characterized by the long hydrothecae, the absence of mesial inferior nematothecae in the hydrocladial internodes, the presence of two axillary nematophores and two ‘mamelons’ in the cauline apophyses and the presence of only secondary hydrocladia (cf. table 1).
 Ecology and distribution. Oswaldella elongata is known only from off Clerke Rocks and South Georgia, where it was found between 86 and 250 m depth, growing on hydrocorals (Peña Cantero et al., 1995).

description: A study is carried out for the design of municipal solid waste management system of Kakonhat municipal area considering integrated approach. Kakonhat is in the Barind tract under Godagari Upazila of Rajshahi district. The existing information is collected and used to design the system. Integrated approach of solid waste management comprises wastes sorting, resource recovery by reusing, recycling and bioconversion and finally sanitary landfill is designed in this study. Landfill liner, cover material, leachate management and landfill gas management are not required in this systembecause of only inert waste materials are disposed in landfill. Total land area required for sanitary landfill in integrated approach is 1279 m2 . The total requirement of manpower, waste collection van and compaction equipment for waste management are of 44 people, 13 numbers and 1 number, respectively. Eventually, the design of solid waste management system will be helpful to develop the Kakonhat municipal area providing the modern facilities to their local people.

description: As a binding material, bitumen is widely used for the construction of wearing course of flexible pavement. The durability of the bituminous mix can be enhanced by use of a binder formed by modifying available bitumen with certain additives like sulphur and organic polymer. The modified binder also improve temperature susceptibility and viscosity characteristics and help alleviating some common problems like bleeding of binder during peak summer temperature and stripping of aggregate in moisture prone areas. The aim of this study is to use of polyethylene and PVC as admixture to bitumen to introduce high quality bituminous mixes for the road construction. This investigation presents some of the experimental results regarding the effect of water on the compressive strength of compacted bituminous mixes with waste polyethylene and PVC. In this investigation 10% waste polyethylene and 7.5% waste PVC was added to the pure bitumen as an admixture to study the compressive strength of the mix. Marshall mix design procedure specified by AASHTO T245-82 was followed in the design and testing of bituminous mixes. On the basis of experimental results of this investigation, optimum bitumen content (OBC) for pure bitumen, polyethylene modified bitumen and PVC modified bitumen were 5.3%, 5.2% and 5.27% respectively. To investigate the effect of water on the compressive strength of bituminous mixes with modified bitumen, specimens were prepared and tested according to the procedures specified by AASHTO T165-86. In this study, the index of the retained strength for both polyethylene and PVC modified bitumen were 89.89% and 85.06% respectively which satisfy the limiting value 75% specified by the ASTM.

description: We present a detailed numerical study of solutions to the (generalized) Zakharov-Kuznetsov equation in two spatial dimensions with various power nonlinearities. In the $L^{2}$-subcritical case, numerical evidence is presented for the stability of solitons and the soliton resolution for generic initial data. In the $L^2$-critical and supercritical cases, solitons appear to be unstable against both dispersion and blow-up. It is conjectured that blow-up happens in finite time and that blow-up solutions have some resemblance of being self-similar, i.e., the blow-up core forms a rightward moving self-similar type rescaled profile with the blow-up happening at infinity in the critical case and at a finite location in the supercritical case. In the $L^{2}$-critical case, the blow-up appears to be similar to the one in the $L^{2}$-critical generalized Korteweg-de Vries equation with the profile being a dynamically rescaled soliton.

description: Policies and programs often aim to improve the affordability of nutritious diets, but existing food price indexes are based on observed quantities which may not meet nutritional goals. To measure changes in the cost of reaching international standards of diet quality, we introduce a new Cost of Diet Diversity index based on consuming at least five different food groups as defined by the widely-used Minimum Dietary Diversity for Women (MDD-W) indicator, and compare those results with the cost of foods needed to meet an adult woman’s estimated average requirements of essential nutrients and dietary energy. Using national average monthly market price data for Ghana from 2009 through 2014, we find that the relative cost of reaching the MDD-W standard fluctuates seasonally and since mid-2010 has risen about 10 percent per year faster than inflation due to rising relative prices for fruit and fish, while the cost of nutrient adequacy rose even faster due primarily to increase cost of foods rich in vitamin A and calcium. Similar data for Tanzania from 2011 through 2015 show small increases in 2011 and 2012 but stable prices thereafter. Our methods can show where and when nutritious diets are increasingly (un)affordable, and which nutritional criteria account for the change. The specific foods included in each index depend on national price monitoring systems, but the method is generalizable to other contexts for monitoring, evaluation, and assessment of changing food environments.
