Varieties of Economic Crisis, Varieties of Ideational Change: How and Why Macroeconomic Policy and Financial Regulation Differ

One of the principal tasks facing post-crash academic political economy is to analyse patterns of ideational change and the conditions that produce such change. What has been missing from the existing literature on ideational change at times of crises however, is a sense of how processes of persuasive struggle, and how the success of those ‘norm entrepreneurs’ arguing for ideational change is shaped by two contextual variables: the most immediate material symptoms and problems that a crisis displays (the variety of crisis); and the institutional character of the policy subsystem that agents have to operate within to affect change. Introducing these two variables into our accounts of persuasive struggle and ideational change enables us to deepen our understanding of the dynamics of ideational change at times of crisis. The article identifies that a quite rapid and radical intellectual change has been evident in the field of financial regulation in the form of an embrace of a macroprudential frame. In contrast in the field of macroeconomic policy - both monetary and fiscal policy, many pre-crash beliefs remain prominent, there is evidence of ideational stickiness and inertia, and despite some policy experimentation, overarching policy frameworks and their rationales have not been overhauled. The article applies Peter Hall’s framework of three orders of policy changes to help illuminate and explain the variation in patterns of change in the fields of financial regulation and macroeconomic policy since the financial crash of 2008. The different patterns of ideational change in macroeconomic policy and financial regulation in the post-crash period can be explained by timing and variety of crisis; sequencing of policy change; and institutional political differences between micro policy sub systems and macro policy systems.

Beyond the standard work model? Varieties of flexible working time in European economies

Working time has been among the first aspect of the employment relation to be the object of intense regulation at the national and supra-national level. This standard regulation of working time comprised a number of elements: full-time hours, rigid working schedules, strong employers’ control and clear boundaries around working time In spite of general claims about the erosion of this model, few studies have investigated this process in a comparative and empirical perspective. The aim of this paper is to investigate the diversity of working time arrangements in European economies by applying latent class analysis to data
from the European Working Conditions Survey (EWCS). This analysis shows the existence of six different types of working time organization highlighting five cross-national patterns: multiple flexibilities, extended flexibility, standard, rigid and fragmented time.

Varieties of resource nationalism in sub-Saharan Africa’s energy and minerals markets

This article examines resource nationalism in sub-Saharan Africa's energy and minerals markets. It does so by exploring economic and political developments in three cases: Nigeria as an example of a petro-state established by means of expropriation in the wake of decolonisation; South Africa, a mature mining industry shaped by its settler colonial history; and Mozambique, a new and therefore highly-dependent entrant into the league of significant natural gas producers. Extractive industries have played a controversial role in sub-Saharan Africa due in particular to the prevalence of the resource curse. Nevertheless, energy exports will continue to play an important role in fuelling economic growth and, potentially, also development as new deposits of natural gas and oil are discovered across the region. Resource nationalism has, moreover, increasingly constrained operations of the traditionally dominant Western energy companies, in particular as competition from state-owned energy companies in sub-Saharan Africa and from emerging powers such as China is increasing.

SHORT-TERM EFFECTS OF SALINITY ON SOME PHYSIOLOGICAL PARAMETERS OF YOUNG OLIVE TREES OF ARBEQUINA, COBRANÇOSA AND GALEGA VARIETIES

SHORT-TERM EFFECTS OF SALINITY ON SOME PHYSIOLOGICAL PARAMETERS OF YOUNG OLIVE TREES OF ARBEQUINA, COBRANÇOSA AND GALEGA VARIETIES Ana Elisa Rato1,4, Renato Coelho1, Margarida Vaz1, Teresa Carola2, Dália Barbosa2, Nádia Silva1, José dos Santos2, Lourenço Machado2, João Godinho2, Luzia Ruas2, Margarida Barradas2, Hernani Pereira2, Sara Porfírio4 1 ICAAM, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 2 Master students, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 3 Ph.D. student, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 4 aerato@uevora.pt Due to the desertification in some regions, the interest in plant’s tolerance to salinity has been increasing, as this response is determining for plant survival in stress conditions. This work reports the investigation of tolerance to salt in two year-old olive trees (Olea europaea L.) of three varieties, Arbequina, Cobrançosa and Galega vulgar. Plants were grown in 10 L plastic pots containing approximately 9 Kg of a sandy granitic soil, on a greenhouse. For 3 months (from the beginning of February to the end of April 2012), they were subjected to three levels of salinity in the irrigation water, 0 mM, 80 mM and 200 mM NaCl (6 plants per salinity level in a total of 18 plants of each variety),. Stomatal conductance (gs) and relative leaf chlorophyll content were assessed on each plant in February, March and April. Mid-day leaf water potential () and soil salinity were measured at the end of the experiment (April). On average, concerning all treatments and dates of determination, stomatal conductance of Arbequina and Galega vulgar was quite similar, around 40 mmol m-2 s-1, but Cobrançosa had a value of gs 36% higher, almost 50% higher (61 mmol m-2 s-1) when compared with the controls (0 mM salt) of the other two varieties. In percentage of controls, there was little difference in gs between varieties and between salinities during February and March. In contrast, in April, after about 90 days of exposure to salt, there was a clear decrease in gs with salt irrigation, proportional to salt concentration. Compared with controls, plants irrigated with 200 mM salt showed around 80% (Arbequina) or 85% (Cobrançosa and Galega vulgar) decrease in gs. Chlorophyll content of leaves showed less than 5% difference between varieties on the average of all treatments and dates of determination. During the course of this experiment, the salinity levels used did not show any relevant effect on chlorophyll content. Overall, at the end of the experimental period (April), leaf water potential () at midday was significantly higher in Cobrançosa (-1,4 MPa) than in Galega vulgar (-1,7 MPa) or Arbequina (-1,8 MPa), and salt decreased  of control plants (-1,25 MPa) by an average 30% (with 80 mM) and 65% (with 200 mM). At the end of the experiment, salinity in the soil irrigated with 0 mM, 80 mM or 200 mM NaCl was, on average of all varieties, 0,2 mS, 1,0 mS or 2,0 mS, respectively. Soil salinity was quite similar in Arbequina and Galega vulgar but about 35% lower in the pots of Cobrançosa, on average of all salt-irrigation levels. Plants of Cobrançosa had higher stomatal conductance, however they showed higher water potential and lower salinity in the soil. These apparently contradictory results seem to suggest that Cobrançosa responds to salt differently from the other two varieties. This issue needs further investigation.

Salinity-induced effects on transpiration rate, stomatal conductance and leaf area of three olive (Olea europaea L.) varieties

Transpiration of two year-old olive trees of three different varieties, Arbequina, Cobrançosa and Galega (18 trees per variety), irrigated with three levels of salt (0, 80 or 200 mM NaCl) for about 90 days, was measured by a gravimetric method. To determine leaf area, each tree was photographed from the side against a white background and the total area of each projected image was determined with ImageJ software. To calibrate these area determinations, one tree of each variety was subsequently stripped of all its leaves and its total leaf area was accurately measured. A correlation was then obtained between the area on the photograph of this particular tree and the total area of the detached leaves of the same tree. Using the leaf area determined by this procedure, transpiration rates of the trees could be calculated. Knowing leaf and air temperatures and RH, it was possible to determine the difference in molar fraction of water between the leaf and the air. Using this and the values of the transpiration rate, stomatal conductance could be calculated (gs calc) and compared with the conductance measured on the same trees with a porometer (gs). Actual leaf area of a plant was 1,40 (Arbequina), 1,42 (Cobrançosa) or 1,24 (Galega) times the area measured with ImageJ on the photograph of the same plant. Leaf area of the trees, on average of all salt irrigations, was significantly higher on Arbequina (0,187 m2) then on the other two varieties (0,138 m2 or 0,148 m2, for Cobrançosa or Galega, respectively), but did not differ significantly in percentage of controls (0 salt). On average of all three varieties, leaf area was also higher on plants irrigated without salt (0,181 m2) than on plants exposed to 80 or 200 mM NaCl (0,152 m2 or 0,140 m2, respectively), which did not differ between them. The same significant difference was observed when leaf area was expressed as percentage of controls. Transpiration rate was significantly higher on Cobrançosa (1,17 mmol m-2 s-1), on average of all treatments, but there were no significant differences between Arbequina (1,08 mmol m-2 s-1) and Galega (0,82 mmol m-2 s-1). In percentage of controls, there were no significant differences between varieties. Salt reduced significantly the transpiration rate in all varieties, both the actual and percentual values, to about 50% or 30% of controls when exposed to 80 mM or 200 mM NaCl, respectively. Stomatal conductance (gs), assessed by porometry, was significantly higher in control plants, mainly in Cobrançosa (102 mmol m-2 s-1), then in Arbequina (77 mmol m-2 s-1) and the lower values were found in Galega (51 mmol m-2 s-1). Salt reduced gs, on average of the three varieties to 30% or 10% of controls on exposure to 80 mM or 200 mM NaCl, respectively. Calculated (gs calc) and measured (gs) values of stomatal conductance showed a close relation between them (0,967, R2 = 0,837) which indicates this non-destructive method to determine whole-plant leaf area to be reasonably accurate.

Response to salinity in young olive trees of three Iberian varieties

Soil salinization is a problem in the Mediterranean region. This paper reports a research on the response to salt in two year-old olive trees (Olea europaea L.) of three Iberian varieties: Arbequina, Cobrançosa and Galega Vulgar. Plants were grown in plastic pots containing approximately 9 Kg of a sandy granitic soil, on a greenhouse at the University of Évora since February 2010. The experiment went from February to April 2012. As a rule, plants were watered every other day alternating salt solution (0 mM, 80 mM or 200 mM NaCl) or tap water. After three months irrigation with the different NaCl solutions, soil electric conductivity and soil water content were significantly higher on salt-irrigated pots. Salt also decreased significantly stomatal conductance (gs) and mid-day leaf water potential (), Cobrançosa having in general higher gs and but lower SLA than the two other varieties. Chlorophyll content of leaves was not affected by salt after this three months exposure to NaCl but was significantly higher on Arbequina and lower on Cobrançosa. In general, hyperspectral reflectance indexes did not show significant correlations with salt irrigation, except for the Photochemical Reflectance Index (PRI) which was clearly lower on plants of all three varieties irrigated with salt. Interestingly, Cobrançosa showed frequently vegetation indexes different from the other two varieties.

Functional genomics of BAHD acyltransferases in different varieties of the wine grape, Vilis vinifera

The characteristic "foxy" aroma of Vilis labrusca Concord grapes is due in large part to methyl anthranilate, a volatile ester formed by the enzyme anthraniloyl- CoA:methanol anthraniloyltransferase (VIAMAT) of the superfamily of BARD acyltransferases. The publication of the genome ofthe closely related wine grape Vilis vinifera, which does not accumulate methyl anthranilate, permitted the searching for any putative VlAU4T-like genes, with the result of 5 highly homologous candidates being found, with one candidate sharing 95% identity to VlAU4T. Probing the gene expression of 18 different cultivars of V. vinifora ripe berries by RT -PCR showed that many varieties do indeed express VlAU4T-like genes. Subsequent cloning of the full-length open reading frame of one of these genes from eDNA prepared from the cultivar Sauvignon Blanc permitted preliminary biochemical characterization of the enzyme after heterologous expression in E. coli. It was determined that this alcohol acyltransferase (named VvsbAATl) catalyzes the formation of cis-3-hexenyl acetate, a "green-leaf' volatile. Although the cloned gene from Sauvignon Blanc had 95% identity at the amino acid level to VIAMAT, it displayed an altered substrate specificity and expression pattern. These results highlight the difficulty in predicting substrate specificity and function of enzymes through the basis of sequence homology, which is a common finding in the study of BARD acyltransferases. Also, the determination of function of VvsbAATl and other BARD acyltransferases in V. vinifera could be used as a genetic marker for certain aroma characteristics in grape breeding programs.

Phytochemical investigations on ‘black glumed’ Njavara (Oryza sativa L.), the medicinal rice, as compared to staple varieties and evaluation of their antioxidant, anti-inflammatory and anticancer effects

The study was planned to investigate the bioactive compounds in Njavara compared to staple varieties and their bioactivity to substantiate the medicinal properties. Results of the study on chemical indices, antioxidant activity and antiinflammatory activity (in vivo) of Njavara black rice bran and rice in comparison with non-medicinal varieties like Sujatha and Palakkadan Matta rice bran and rice are given. The phytochemical investigation and quantification of Njavara extracts in comparison with staple varieties are detailed in this study. The last chapter is divided in three sections (A, B and C). Section A comprises the antioxidant activity by in vitro assays like DPPH, superoxide anion radical and hydrogen peroxide scavenging activity of the compounds. Also, theoretical studies using DFT were carried out based on DPPH radical scavenging activity for understanding the radical stability and mechanism of antioxidant activity. Section B comprises the anti-inflammatory activity of the identified compounds namely tricin and two flavonolignans in both in vivo and in vitro models. Section C describes the cytotoxicity of the rare flavonolignans, tricin 4’-O-(erythro-β-guaiacylglyceryl) ether and tricin 4’-O-(threo-β-guaiacylglyceryl) ether towards multiple cancer cells belonging to colon, ovarian and breast tumours.

Organic potatoes for processing

Drei Feldversuche auf zwei Standorten (DFH: 51°4, 9°4’, BEL: 52°2’, 8°08’) wurden in den Jahren 2002 bis 2004 durchgeführt, um den Einfluss der Vorfrucht, des Vorkeimens, der N- und K-Düngung und der Sorte auf Nährstoffverfügbarkeit, Gesamt- und sortierte Knollenerträge sowie die Qualität von Kartoffeln und deren Eignung für die industrielle Verarbeitung zu Pommes frites und Chips zu untersuchen. Bestimmt wurden die N- und K-Verfügbarkeit im Boden, die N- und K-Aufnahme von Kraut und Knollen, gesamte Frisch- und Trockenmasseerträge, sortierte Frischmasseerträge für die Verarbeitung, sowie die Gehalte der Knollen an Trockensubstanz und reduzierenden Zuckern. In einer sensorischen Prüfung wurden Qualitätsparameter von Pommes frites (Aussehen/Farbe, Textur und Geschmack/Geruch) bewertet, die gewichtet in einen Qualitätsindex eingingen. Die Qualität der Chips wurde maschinell durch den L-Wert (Helligkeit) des Produktes quantifiziert. Der Gehalt des Bodens an mineralisiertem Nitrat-Stickstoff hing von der Vorfrucht und dem Jahr ab. Nach Erbsen wurden zum Auflaufen der Kartoffeln in den Versuchsjahren 2003 und 2004 (187 und 132 kg NO3-N ha-1) die höchsten NO3-N-Werte in 0-60 cm Boden gemessen verglichen mit Kleegras (169 bzw. 108 kg NO3-N ha-1 oder Getreide (112 kg bzw. 97 kg NO3-N ha-1), obgleich die Differenz nicht in allen Fällen signifikant war. Entsprechend wurden nach Erbsen die höchsten Knollen-Frischmasseerträge (414 und 308 dt ha-1) geerntet. Dasselbe galt für die Trockenmasserträge, was belegt, dass der Trockensubstanzgehalt der Knollen bei verbesserter N-Versorgung nicht im selben Maße sinkt, wie der Frischmasseertrag steigt. Das Vorkeimen der Pflanzknollen führte zu einer rascheren phänologischen Entwicklung im Jugendstadium der Pflanze, beschleunigter Trockenmassebildung des Krautes und einer früheren Einlagerung von Assimilaten vom Kraut in die Knollen. Obwohl die positive Wirkung des Vorkeimens auf den Gesamtertrag bis Ende Juli (+ 26 in 2003 bzw. 34 dt ha-1 in 2004) im Jahr ohne Krautfäuleepidemie von den nicht vorgekeimten Varianten bis zur Endernte im September kompensiert wurde, konnte in diesem Jahr durch Vorkeimen dennoch ein erhöhter Ertragsanteil (+ 12%) der besonders nachgefragten Übergrößen (>50 mm für Pommes frites) erzielt werden. Die durchschnittliche Knollenmasse reagierte positiv auf Vorkeimen (+ 5,4 g), Sortenwahl (Sorte Agria) und ein erhöhtes N-Angebot (Leguminosenvorfrucht). Generell wurde deutlich, dass die Knollengesamterträge unter den Bedingungen des Ökologischen Landbaus (geringe bis mittlere Nährstoffversorgung, verkürzte Vegetationsdauer) sehr stark vom Anbaujahr abhängen. Die Ergebnisse belegen jedoch, dass organisch-mineralische N-K-Düngung den sortierten Ertrag an Knollen für die Verarbeitung signifikant erhöht: Höchste Gesamt- und sortierte Knollenfrischmasseerträge wurden nach kombinierter N (Horngrieß) und mineralischer K- (Kaliumsulfat) Gabe erzielt (348 dt ha-1 im Durchschnitt von 2002-2004). Im Gegensatz dazu kann eine Wirkung von Stallmist auf den Ertrag im Jahr der Ausbringung nicht unbedingt erwartet werden. Steigende Erträge nach Stallmistdüngung wurden lediglich in einem von drei Versuchsjahren (+58 dt ha-1) festgestellt und ließen sich eher auf eine K- als eine N-Wirkung zurückführen. Die Ergebnisse belegen, dass die Sortenwahl eine entscheidende Rolle spielt, wenn die Kartoffeln für die industrielle Verarbeitung zu den oben genannten Produkten angebaut werden. Insgesamt kann festgestellt werden, dass Kartoffelknollen aus ökologischen Anbauverfahren ausreichend hohe Trockensubstanzgehalte aufweisen, um für die Verarbeitung zu Pommes frites (>19%) geeignet zu sein und ohne dass dadurch die Konsistenz des Endproduktes gefährdet würde. Der Trockensubstanzgehalt der Referenzsorte für Chips, „Marlen“, unterschritt das in der Literatur geforderte Minimum für Chips von 23% lediglich, wenn die kombinierte Horngrieß-Kaliumsulfatdüngung zur Anwendung kam. Die Trockensubstanzgehalte der Knollen konnten durch Vorkeimen signifikant gesteigert werden und der Effekt war besonders groß (+1.2% absolut) in dem Jahr mit frühem Auftreten der Krautfäule (Phytophthora infestans), d.h. verkürzter Vegetationszeit. Die Knollen-Trockensubstanzgehalte waren in zwei von drei Experimenten nach Lagerung höher (+0.4 und 0.5% absolut) als noch zur Ernte. Sorten der sehr frühen und frühen Reifegruppe wiesen den größten relativen Anstieg der Gehalte an reduzierenden Zuckern (Glukose und Fruktose) während der Lagerung auf. Den mittelfrühen Sorten „Agria“ und „Marena“ hingegen kann aufgrund des von ihnen erreichten höchsten Qualitätsstandards (Pommes frites) zur Ernte eine sehr gute Eignung für die Bedingungen des Ökologischen Landbaus unterstellt werden. Die durchgehend beste Chipseignung wies die mittelfrühe Referenzsorte „Marlen“ auf. Insgesamt konnte nachgewiesen werden, dass durch gezielte Sortenwahl der Trockensubstanzgehalt und die Konzentration reduzierender Zucker, sowie die Qualität der Endprodukte (Pommes frites und Chips) gezielt beeinflusst werden kann. Im Gegensatz dazu haben acker- und pflanzenbauliche Maßnahmen wie Düngung, Wahl der Vorfrucht und Vorkeimen der Pflanzknollen einen eher geringen Einfluss. Dementsprechend sollte der Landwirt versuchen, durch die Wahl der Sorte den hohen Anforderungen der Industrie an die Rohware gerecht zu werden.
