Supplemental Nutrition Assistance Program: A policy analysis of restricting foods with minimal nutritional value

In 2011, expenditures for the Supplemental Nutrition Assistance Program (SNAP) reached an all-time high of $72 billion. The goal of SNAP is " to alleviate hunger and malnutrition…by increasing food purchasing power for all eligible households who apply for participation." It has been well established that proper nutrition is essential to good health, making SNAP an important program to public health consumers. Thus, this analysis examined whether SNAP is meeting its stated goal and whether the goal would be reduced if the purchase of foods of minimal nutritional value (FMNV) were restricted. ^ A review of existing literature found that SNAP has been shown to alleviate hunger, but the studies on the nutritional impact of the program were not sufficient to assert whether change is needed. When considering whether limiting FMNV would reduce or improve the effectiveness of SNAP at alleviating hunger and malnutrition, there is very little information on which to base a policy change, particular one that singles out a low income group to restrict purchases. ^ Several states have attempted to restrict the purchase of FMNV but, to date, no such change has been implemented or tested. Conducting pilot studies on the restriction of FMNV, along with better data collection on SNAP purchases, would guide policy changes to the program. Although there are many potential public health benefits to restricting FMNV purchase using SNAP dollars, research is needed to quantify the cost impact of these benefits.^

Quantitative component analysis of the coarse fraction of surface sediments from the Persian Gulf

In the Persian Gulf and the Gulf of Oman marl forms the primary sediment cover, particularly on the Iranian side. A detailed quantitative description of the sediment components > 63 µ has been attempted in order to establish the regional distribution of the most important constituents as well as the criteria governing marl sedimentation in general. During the course of the analysis, the sand fraction from about 160 bottom-surface samples was split into 5 phi° fractions and 500 to 800 grains were counted in each individual fraction. The grains were cataloged in up to 40 grain type catagories. The gravel fraction was counted separately and the values calculated as weight percent. Basic for understanding the mode of formation of the marl sediment is the "rule" of independent availability of component groups. It states that the sedimentation of different component groups takes place independently, and that variation in the quantity of one component is independent of the presence or absence of other components. This means, for example, that different grain size spectrums are not necessarily developed through transport sorting. In the Persian Gulf they are more likely the result of differences in the amount of clay-rich fine sediment brought in to the restricted mouth areas of the Iranian rivers. These local increases in clayey sediment dilute the autochthonous, for the most part carbonate, coarse fraction. This also explains the frequent facies changes from carbonate to clayey marl. The main constituent groups of the coarse fraction are faecal pellets and lumps, the non carbonate mineral components, the Pleistocene relict sediment, the benthonic biogene components and the plankton. Faecal pellets and lumps are formed through grain size transformation of fine sediment. Higher percentages of these components can be correlated to large amounts of fine sediment and organic C. No discernable change takes place in carbonate minerals as a result of digestion and faecal pellet formation. The non-carbonate sand components originate from several unrelated sources and can be distinguished by their different grain size spectrum; as well as by other characteristics. The Iranian rivers supply the greatest amounts (well sorted fine sand). Their quantitative variations can be used to trace fine sediment transport directions. Similar mineral maxima in the sediment of the Gulf of Oman mark the path of the Persian Gulf outflow water. Far out from the coast, the basin bottoms in places contain abundant relict minerals (poorly sorted medium sand) and localized areas of reworked salt dome material (medium sand to gravel). Wind transport produces only a minimal "background value" of mineral components (very fine sand). Biogenic and non-biogenic relict sediments can be placed in separate component groups with the help of several petrographic criteria. Part of the relict sediment (well sorted fine sand) is allochthonous and was derived from the terrigenous sediment of river mouths. The main part (coarse, poorly sorted sediment), however, was derived from the late Pleistocene and forms a quasi-autochthonous cover over wide areas which receive little recent sedimentation. Bioturbation results in a mixing of the relict sediment with the overlying younger sediment. Resulting vertical sediment displacement of more than 2.5 m has been observed. This vertical mixing of relict sediment is also partially responsible for the present day grain size anomalies (coarse sediment in deep water) found in the Persian Gulf. The mainly aragonitic components forming the relict sediment show a finely subdivided facies pattern reflecting the paleogeography of carbonate tidal flats dating from the post Pleistocene transgression. Standstill periods are reflected at 110 -125m (shelf break), 64-61 m and 53-41 m (e.g. coare grained quartz and oolite concentrations), and at 25-30m. Comparing these depths to similar occurrences on other shelf regions (e. g. Timor Sea) leads to the conclusion that at this time minimal tectonic activity was taking place in the Persian Gulf. The Pleistocene climate, as evidenced by the absence of Iranian river sediment, was probably drier than the present day Persian Gulf climate. Foremost among the benthonic biogene components are the foraminifera and mollusks. When a ratio is set up between the two, it can be seen that each group is very sensitive to bottom type, i.e., the production of benthonic mollusca increases when a stable (hard) bottom is present whereas the foraminifera favour a soft bottom. In this way, regardless of the grain size, areas with high and low rates of recent sedimentation can be sharply defined. The almost complete absence of mollusks in water deeper than 200 to 300 m gives a rough sedimentologic water depth indicator. The sum of the benthonic foraminifera and mollusca was used as a relative constant reference value for the investigation of many other sediment components. The ratio between arenaceous foraminifera and those with carbonate shells shows a direct relationship to the amount of coarse grained material in the sediment as the frequence of arenaceous foraminifera depends heavily on the availability of sand grains. The nearness of "open" coasts (Iranian river mouths) is directly reflected in the high percentage of plant remains, and indirectly by the increased numbers of ostracods and vertebrates. Plant fragments do not reach their ultimate point of deposition in a free swimming state, but are transported along with the remainder of the terrigenous fine sediment. The echinoderms (mainly echinoids in the West Basin and ophiuroids in the Central Basin) attain their maximum development at the greatest depth reached by the action of the largest waves. This depth varies, depending on the exposure of the slope to the waves, between 12 to 14 and 30 to 35 m. Corals and bryozoans have proved to be good indicators of stable unchanging bottom conditions. Although bryozoans and alcyonarian spiculae are independent of water depth, scleractinians thrive only above 25 to 30 m. The beginning of recent reef growth (restricted by low winter temperatures) was seen only in one single area - on a shoal under 16 m of water. The coarse plankton fraction was studied primarily through the use of a plankton-benthos ratio. The increase in planktonic foraminifera with increasing water depth is here heavily masked by the "Adjacent sea effect" of the Persian Gulf: for the most part the foraminifera have drifted in from the Gulf of Oman. In contrast, the planktonic mollusks are able to colonize the entire Persian Gulf water body. Their amount in the plankton-benthos ratio always increases with water depth and thereby gives a reliable picture of local water depth variations. This holds true to a depth of around 400 m (corresponding to 80-90 % plankton). This water depth effect can be removed by graphical analysis, allowing the percentage of planktonic mollusks per total sample to be used as a reference base for relative sedimentation rate (sedimentation index). These values vary between 1 and > 1000 and thereby agree well with all the other lines of evidence. The "pteropod ooze" facies is then markedly dependent on the sedimentation rate and can theoretically develop at any depth greater than 65 m (proven at 80 m). It should certainly no longer be thought of as "deep sea" sediment. Based on the component distribution diagrams, grain size and carbonate content, the sediments of the Persian Gulf and the Gulf of Oman can be grouped into 5 provisional facies divisions (Chapt.19). Particularly noteworthy among these are first, the fine grained clayey marl facies occupying the 9 narrow outflow areas of rivers, and second, the coarse grained, high-carbonate marl facies rich in relict sediment which covers wide sediment-poor areas of the basin bottoms. Sediment transport is for the most part restricted to grain sizes < 150 µ and in shallow water is largely coast-parallel due to wave action at times supplemented by tidal currents. Below the wave base gravity transport prevails. The only current capable of moving sediment is the Persian Gulf outflow water in the Gulf of Oman.

Particulate organic matter (POM) of samples from the Lena River delta

Particulate organic matter (POM) derived from permafrost soils and transported by the Lena River represents a quantitatively important terrestrial carbon pool exported to Laptev Sea sediments (next to POM derived from coastal erosion). Its fate in a future warming Arctic, i.e., its remobilization and remineralization after permafrost thawing as well as its transport pathways to and sequestration in marine sediments, is currently under debate. We present one of the first radiocarbon (14C) data sets for surface water POM within the Lena Delta sampled in the summers of 2009 - 2010 and spring 2011 (n = 30 samples). The bulk D14C values varied from -55 to -391 per mil translating into 14C ages of 395 to 3920 years BP. We further estimated the fraction of soil-derived POM to our samples based on (1) particulate organic carbon to particulate nitrogen ratios (POC : PN) and (2) on the stable carbon isotope (d13C) composition of our samples. Assuming that this phytoplankton POM has a modern 14C concentration, we inferred the 14C concentrations of the soil-derived POM fractions. The results ranged from -322 to -884 per mil (i.e., 3060 to 17 250 14C years BP) for the POC : PN-based scenario and from -261 to -944 per mil (i.e., 2370 to 23 100 14C years BP) for the d13C-based scenario. Despite the limitations of our approach, the estimated D14C values of the soil-derived POM fractions seem to reflect the heterogeneous 14C concentrations of the Lena River catchment soils covering a range from Holocene to Pleistocene ages better than the bulk POM D14C values. We further used a dual-carbon-isotope three-end-member mixing model to distinguish between POM contributions from Holocene soils and Pleistocene Ice Complex (IC) deposits to our soil-derived POM fraction. IC contributions are comparatively low (mean of 0.14) compared to Holocene soils (mean of 0.32) and riverine phytoplankton (mean of 0.55), which could be explained with the restricted spatial distribution of IC deposits within the Lena catchment. Based on our newly calculated soil-derived POM D14C values, we propose an isotopic range for the riverine soil-derived POM end member with D14C of -495 ± 153 per mil deduced from our d13C-based binary mixing model and d13C of -26.6 ± 1 per mil deduced from our data of Lena Delta soils and literature values. These estimates can help to improve the dual-carbon-isotope simulations used to quantify contributions from riverine soil POM, Pleistocene IC POM from coastal erosion, and marine POM in Siberian shelf sediments.

Discursive constructions of social and environmental accounting in Brazil: the case of Petrobras.

In the 29 years following \"Our Common Future\" by the United Nations, there is considerable debate among governments, civil society, interest groups and business organisations about what constitutes sustainable development, which constitutes evidence for a contested discourse concerning sustainability. The purpose of this study is to understand this debate in the developing economic context of Brazil, and in particular, to understand and critique the social and environmental accounting [SEA] discursive constructions relating to the State-owned, Petrobras as well as to understand the Brazilian literature on SEA. The discourse theory [DT]-based analysis employs rhetorical redescription to analyse twenty-two reports from Petrobras from 2004-2013. I investigate the political notions by employing the methodological framework of the Logics of Critical Explanation [LCE]. LCE engenders five methodological steps: problematisation, retroduction, logics (social, political and fantasmatic), articulation and critique. The empirical discussion suggests that the hegemony of economic development operates to obfuscate, rhetorically, the development of sustainability, so as to maintain the core business of Petrobras conceived as capital accumulation. Equally, these articulations also illustrate how the constructions of SEA operate to serve the company\'s purpose with few (none) profound changes in integration of sustainability. The Brazilian literature on SEA sustains the status quo of neo-liberal market policies that operate to protect the dominant business case approach to maintain an agenda of wealth-creation in relation to social and environmental needs. The articulations of the case manifested in policies regarding, for example, corruption, which involved over-payments for contracts and unsustainable practices relating to the use of fossil fuels and demonstrated that there was antagonism between action and disclosure. The corruption scandal that emerged after SEA disclosures highlighted the rhetorical nature of disclosure when financial resources were subtracted from the company for political parties and engineering contractors hid facts through incomplete disclosures. The articulations of SEA misrepresent a broader context of the meanings associated with sustainability, which restricted the constructions of SEA to principally serve and represent the intention of the most powerful groups. The significance of SEA, then is narrowed to represent particular interests. The study argues for more critical studies as limited Brazilian literature concerning SEA kept a \'safe distance\' from substantively critiquing the constructions of SEA and its articulations in the Brazilian context. The literature review and the Petrobras\' case illustrate a variety of naming, instituting and articulatory practices that endeavour to maintain the current hegemony of development in an emerging economy, which allows Petrobras to continue to exercise significant profit at the expense of the social and environmental. The constructed idea of development in Petrobras\' discourses emphasises a rhetoric of wider development, but, in reality, these discourses were the antithesis of political, social and ethical developmental issues. These constructions aim to hide struggles between social inequalities and exploitation of natural resources and constitute excuses about a fanciful notion of rhetorical and hegemonic neo-liberal development. In summary, this thesis contributes to the prior literature in five ways: (i) the addition of DT to the analysis of SEA enhances the discussion of political elements such as hegemony, antagonism, logic of equivalence/difference, ideology and articulation; (ii) the analysis of an emerging economy such as Brazil incorporates a new perspective of the discussion of the discourses of SEA and development; (iii) this thesis includes a focus on rhetoric to discuss the maintenance of the status quo; (iv) the holistic structure of the LCE approach enlarges the understanding of the social, political and fantasmatic logics of SEA studies and; (v) this thesis combines an analysis of the literature and the case of Petrobras to characterise and critique the state of the Brazilian academy and its impacts and reflections on the significance of SEA. This thesis, therefore, argues for more critical studies in the Brazilian academy due to the persistence of idea of SEA and development that takes-for-granted deep exclusions and contradictions and provide little space for critiques.

With or without you...judging politically in the field of Area of Freedom, Security and Justice? Research Papers in Law, 3/2007

From the Introduction. The study of the European Court of Justice’s (ECJ) case law of the regarding the Area of Freedom Security and Justice (AFSJ) is fascinating in many ways.1 First, almost the totality of the relevant case law is extremely recent, thereby marking the first ‘foundational’ steps in this field of law. This is the result of the fact that the AFSJ was set up by the Treaty of Amsterdam in 1997 and only entered into force in May 1999.2 Second, as the AFSJ is a new field of EU competence, it sets afresh all the fundamental questions – both political and legal – triggered by European integration, namely in terms of: a) distribution of powers between the Union and its member states, b) attribution of competences between the various EU Institutions, c) direct effect and supremacy of EU rules, d) scope of competence of the ECJ, and e) measure of the protection given to fundamental rights. The above questions beg for answers which should take into account both the extremely sensible fields of law upon which the AFSJ is anchored, and the EU’s highly inconvenient three-pillar institutional framework.3 Third, and as a consequence of the above, the vast majority of the ECJ’s judgments relating to the AFSJ are a) delivered by the Full Court or, at least, the Grand Chamber, b) with the intervention of great many member states and c) often obscure in content. This is due to the fact that the Court is called upon to set the foundational rules in a new field of EU law, often trying to accommodate divergent considerations, not all of which are strictly legal.4 Fourth, the case law of the Court relating to the AFSJ, touches upon a vast variety of topics which are not necessarily related to one another. This is why it is essential to limit the scope of this study. The content of, and steering for, the AFSJ were given by the Tampere European Council, in October 1999. According to the Tampere Conclusions, the AFSJ should consist of four key elements: a) a common immigration and asylum policy, b) judicial cooperation in both civil and penal matters, c) action against criminality and d) external action of the EU in all the above fields. Moreover, the AFSJ is to a large extent based on the Schengen acquis. The latter has been ‘communautarised’5 by the Treaty of Amsterdam and further ‘ventilated’ between the first and third pillars by decisions 1999/435 and 1999/436.6 Judicial cooperation in civil matters, mainly by means of international conventions (such as the Rome Convention of 1981 on the law applicable to contractual obligations) and regulations (such as (EC) 44/20017 and (EC) 1348/20008) also form part of the AFSJ. However, the relevant case law of the ECJ will not be examined in the present contribution.9 Similarly, the judgments of the Court delivered in the course of Article 226 EC proceedings against member states, will be omitted.10 Even after setting aside the above case law and notwithstanding the fact that the AFSJ only dates as far back as May 1999, the judgments of the ECJ are numerous. A simple (if not simplistic) categorisation may be between, on the one hand, judgments which concern the institutional setting of the AFSJ (para. 2) and, on the other, judgments which are related to some substantive AFSJ policy (para. 3).
