title: The Reflective Mariner An Approach for ECDIS Training and Operational Usage
Creators: name: Muller, Scott W.
Publisher: name: Old Dominion University Libraries
Year: 2006

description: The emergence of the Electronic Chart Display and Information System (ECDIS) on the bridge of modem vessels offers the possibility of improving the safety and efficiency of maritime operations. Despite its benefits, improper use of ECDIS relegates the watch officer to passive monitoring, which in tum places the mariner "out of the control loop" in the assessment of vessel control functions and equipment malfunctions. It is therefore vital to train mariners to be active in their ECDIS monitoring. This thesis presents a training strategy aimed at developing the "Reflective Mariner": an approach to help mariners maintain their active use of ECDIS. The training strategy developed here incorporates the use of marine simulation and After Event Reviews (AERs), a reflective process of learning from past events. To demonstrate the feasibility of the Reflective Mariner training strategy, an experiment was conducted using Kings Point Merchant Marine Academy deck cadets operating an integrated bridge simulator to examine the effect of AERs on learners' navigational performance and causal attributions under conditions of (a) ECDIS failure and (b) past performance. Due to the small sample size (five participants) and the limited amount and precision of the data, the results did not ' substantiate the experimental hypotheses. However, the results of the study provided the following insights on AERs and ECDIS use in general: (1) AERs reorganized the causal attributional statements, (2) participants with higher ECDIS familiarity attributed failed performance to higher levels of ECDIS over-reliance, and (3) reflection on past performance bolstered epistemic cognition, regardless of the particular type of reflective process used. This thesis concludes with implications and recommendations for further research in marine safety through developing the notion of the Reflective Mariner.

description: This article examines the current stage of WTO negotiations on agriculture and discusses the power structure in major players in the negotiations. The difficulty to reach agreement in WTO leads many counties to FTA for further liberalization in trade. But agricultural sector tends to be a stumbling block there also. To discuss agricultural issues in FTA three countries of China, Japan and Korea are selected for an example of a multiple country FTA in Asia. Examined are how agricultural should be treated and possibility of substantially including agricultural sector in China-Japan-Korea FTA. Despite the difficulties, agricultural sector should be included in the list of tariff reductions for the C-J-K FTA. It is a good opportunity for reforming agricultural sector to be viable in international competition toward the total globalization. It is no doubt that the direction of world agricultural trade is toward freer trade. FTA is a good step for that and provides preparation for a global integration of agricultural trade. It may be desirable to establish an international forum, particularly among Asian countries, to discuss important agricultural issues in the region. This forum should consider not only agricultural tariff reductions, but also sanitary and phyto-sanitary (SPS) measures that might be addressed in working toward a broader FTA in Asia. In organizing such a forum that shall be called "Agricultural Partnership in Asia" for wider cooperation of agricultural policy and agricultural resource management in Asia, China, Japan and Korea should take a strong leadership and make substantial steps toward the domestic agricultural reforms as well. It may lead the region to establishing an Asian type of Common Agricultural Policy in the future.

description: Two-dimensional Na$_3$Bi is a dual topological insulator protected by time-reversal and mirror symmetry, resulting in a promising platform for devices design. However, in reality, the design of topological devices is hindered by a sensitivity against disorder and temperature. We study the topological properties of Na$_3$Bi in the presence of intrinsic defects, investigating the robustness of the edge states and the resulting transport properties. We apply a recursive Green's function technique enabling the study of disordered systems with lengths comparable to experimentally synthesized materials, in the order of micrometers. We combine our findings to propose a topological insulator device, where intrinsic defects are used to filter the response of trivial bulk states. This results in a stable conductance throughout a large range of electronic temperatures, and controllable by a perpendicular electric field. Our proposal is general, enabling the design of various dual topological insulators devices.

description: Malawi is facing a severe HIV/AIDS Pandemic. With an estimated prevalence rate of 14.2%, it ranks eight in the world. About 900,000 Malawians were infected by 2003 and there were110,000 new infections and 87,000 deaths due to HIV/AIDS in 2003. The disease has poten tially devastating impacts. For example, 'taking children out of school' is mentioned as one of the coping mechanisms (Garbus 2003) but evidence is mixed. Doctor (2004) found no statistically significant difference between enrollment of orphans and non-orphans and mentioned an effective extended family structure as explanation. However, HIV/AIDS, poverty, macroeconomic policies, and food shortages are reported to render informal safety networks of the extended family systems irrelevant (Garbus 2003). Some evidence seems to point in this direction (Nankhuni 2005). This research shows that adolescents who are orphaned and those who do not live with their parents are less likely to attend school, spend less hours on school work but more hours on domestic and paid work. Children in households that have adults with chronic illnesses that are associated with HIV/AIDS symptoms are also more likely to be absent from school and spend more hours on d omestic and paid work. These results suggest that HIV/AIDS contributes to low investments in children in Malawi. The results also suggest that the extended family system is weakening due to pressure from increased number of orphans and the low economic status of most Malawians since even parents that are living foster out their children and these children do worse than orphaned children.

description: To complement the optical absorption-line survey of diffuse molecular gas in Paper I, we obtained and analyzed far ultraviolet H$_2$ and CO data on lines of sight toward stars in Cep OB2 and Cep OB3. Possible correlations between column densities of different species for individual velocity components, not total columns along a line of sight as in the past, were examined and were interpreted in terms of cloud structure. The analysis reveals that there are two kinds of CH in diffuse molecular gas: CN-like CH and CH$^+$-like CH. Evidence is provided that CO is also associated with CN in diffuse molecular clouds. Different species are distributed according to gas density in the diffuse molecular gas. Both calcium and potassium may be depleted onto grains in high density gas, but with different dependences on local gas density. Gas densities for components where CN was detected were inferred from a chemical model. Analysis of cloud structure indicates that our data are generally consistent with the large-scale structure suggested by maps of CO millimeter-wave emission. On small scales, the gas density is seen to vary by factors greater than 5.0 over scales of $\sim$ 10,000 AU. The relationships between column densities of CO and CH with that of H$_2$ along a line of sight show similar slopes for the gas toward Cep OB2 and OB3, but the CO/H$_2$ and CH/H$_2$ ratios tend to differ which we ascribe to variation in average density along the line of sight.

description: Current government guidelines for the appraisal of coastal defence projects in the UK do not require that non-market amenity benefits to be considered . However, a new option in coastal defence, namely multi-purpose reefs, provides an opportunity to integrate coastal defence with significant amenity provision. This paper reports the findings of a choice experiment study that evaluated the amenity benefits of four alternative coastal defence systems currently being considered for Borth in west Wales. The results indicate that traditional coastal defence options such as timber and rock groynes do not generate amenity benefits, while a multipurpose reef would generate significant benefits in terms of improvements in the visual appeal of the beach, safer swimming opportunities and improved surfing conditions. Importantly, these benefits were found to be significant for all members of the local community and not just surf ers. Based on our findings, we recommend that guidelines for the appraisal of coastal defence projects should be amended to incorporate non-market amenity benefits.

description: We introduce an exact algorithm for the computation of spin correlation functions for the two dimensional +/-J Ising spin glass in the ground state. Unlike with the transfer matrix method, there is no particular restriction on the shape of the lattice sample, and unlike Monte Carlo based methods it avoids extrapolation from finite temperatures. The computational requirements depend only on the number and distribution of frustrated plaquettes.

Demand and Price Analysis

description: Agricultural trade between the U.S. and Mexico has become progressively liberalized over the past 20 years, with significant increases in bilateral trade in many sectors. The rice sector in both nations, however, continues to be highly protected, with producers and millers on both sides of the border continuing to protest the other nation's protectionist policies. This paper examines market efficiency and spatial price integration in ten U.S. and Mexican rice markets over the 1998-2002 period, during which a retaliatory antidumping duty was imposed by Mexico. The paper uses a multiple step analytical process, including analysis of market price differentials, stationarity tests, bivariate and multivariate cointegration tests, and impulse response analysis. Based on the cointegration results, long-run equilibrating relationships are shown to bind most Mexican markets to U.S. markets, and the U.S. markets are shown to be integrated with continuity. Smaller and more remote Mexican markets located far from transport hubs and milling centers tend not to be integrated with other regions, suffer from information asymmetries, and are characterized by relatively high price levels. In large markets where tariffs tend to be binding, trade policy plays a key role in determining equilibrium market relationships. For example, the tariff structure largely determines whether rice consumed in Mexico will primarily be milled domestically or in the U.S. in the long run. Overall, the results suggest that while consumers in major urban centers have benefited from freer trade, those in remote rural markets have yet to realize significant gains from liberalized rice markets.

description: To determine whether the Shapiro time delay of light passing near a moving object depends on the ``speed of gravity'' or the ``speed of light,'' one must analyze observations in a bimetric framework in which these two speeds can be different. In a recent comment (gr-qc/0510048), Kopeikin has argued that such a computation -- described in gr-qc/0403060 -- missed a hidden dependence on the speed of gravity. By analyzing the observables in the relevant bimetric model, I show that this claim is incorrect, and that the conclusions of gr-qc/0403060 stand.

description: Poverty alleviation has been the main target of developmental projects world-wide. However, only a few ideas have stirred so much attention in the last two decades as that of the provision of microfinance through specialised institutions. This paper provides a survey of the vast literature that has developed in this field. Though most of the evidence and literature on the subject appears self-praising, nonetheless there is much more to the concept than one can imagine. The establishment of microfinance institutions (MFIs) world-wide for the provision of collateral free loans to the poor through mechanisms and instruments not known to normal commercial banks has set new milestones in the field of financial services. With 900 million households in the less developed countries left without any access to formal financial services, this might just be the key to address market failures in the financial landscape.

The statistics of the wavefunction are left unspecified. Using the properties of the Weyl group, we are also able to find Bethe equations. It is notable that the method relies on a certain generalized version of the well-known Yang-Baxter equation. A particular class of non-trivial solutions to this equation emerges naturally.

description: We investigate transport through hybrid structures consisting of two normal metal leads connected via tunnel barriers to one common superconducting electrode. We find clear evidence for the occurrence of non-local Andreev reflection and elastic cotunneling through superconductor when the separation of the tunnel barrier is comparable to the superconducting coherence length. The probability of the two processes is energy dependent, with elastic cotunneling dominating at low energy and non-local Andreev reflection at higher energies. The energy scale of the crossover is found to be the Thouless energy of the superconductor, which indicates the phase coherence of the processes. Our results are relevant for the realization of recently proposed entangler devices.

description: We consider the QCD corrections to the electric dipole moment of the neutron in the Minimal Supersymmetric Standard Model. We provide a master formula for the Wilson coefficients at the low energy scale including for the first time the mixing between the electric and chromoelectric operators and correcting widely used previous LO estimates. We show that, because of the mixing between the electric and chromoelectric operators, the neutralino contribution is always strongly suppressed. We find that, in general, the effect of the QCD corrections is to reduce the amount of CP violation generated at the high scale. We discuss the perturbative uncertainties of the LO computation, which are particularly large for the gluino-mediated contribution. This motivates our Next-to-Leading order analysis. We compute for the first time the order alpha_s corrections to the Wilson coefficients for the gluino contributions, and recompute the two-loop anomalous dimension for the dipole operators. We show that the large LO uncertainty disappears once NLO corrections are taken into account.

description: Nematic liquid crystals in a polyhedral domain, a prototype for bistable displays, may be described by a unit-vector field subject to tangent boundary conditions. Here we consider the case of a rectangular prism. For configurations with reflection-symmetric topologies, we derive a new lower bound for the one-constant elastic energy. For certain topologies, called conformal and anticonformal, the lower bound agrees with a previous result. For the remaining topologies, called nonconformal, the new bound is an improvement. For nonconformal topologies we derive an upper bound, which differs from the lower bound by a factor depending only on the aspect ratios of the prism.

Die vorliegende Bachelorarbeit ist ein Forschungsprojekt und geht der Frage nach, wie gerade Berufseinsteigende der Sozialen Arbeit mit dem Hintergrund der eigenen Biographie professionell Handeln können und was dabei beachtet werden muss. Mittels Leitfaden-Interviews mit sechs Berufseinsteigenden wurden die Daten erhoben und anschliessend mit einer qualitativen Inhaltsanalyse ausgewertet. Die Auswertung zeigt auf, dass sich biographische Einflüsse in den Bereichen Familie, Herkunft, Kindheit, Jugend, Geschlecht, Alter, Migrationshintergrund sowie Erfahrungen in beruflichen und nicht beruflichen Tätigkeiten und im Studium der Sozialen Arbeit auf das professionelle Handeln von Berufseinsteigenden auswirken können. Diese Auswirkungen können sowohl förderlich als auch hinderlich für das professionelle Handeln sein. Biographiearbeit in Form von Selbstreflexion, Super- oder Intervision ermöglicht das Erkennen dieser Wirkungen auf das professionelle Handeln in der Sozialen Arbeit. Aus den gewonnenen Erkenntnissen dieser Arbeit wurden anschliessend Handlungsempfehlungen für die Praxis abgeleitet. Dabei wurden drei Ebenen berücksichtigt: Die persönliche-, die betriebliche- sowie die Ausbildungsebene der Fachpersonen. Diese Bachelorarbeit ermöglicht somit einen Beitrag zur Förderung des professionellen Handelns in der Sozialen Arbeit.

description: The reaction gamma p --> K0 Sigma+ was measured in the photon energy range from threshold up to 2.6 GeV with the SAPHIR detector at the electron stretcher facility, ELSA, in Bonn. Results are presented on the reaction cross section and the polarization of the Sigma+ as a function of the kaon production angle in the centre-of-mass system, cos(Theta_K^{c.m.}), and the photon energy. The cross section is lower and varies less with photon energy and kaon production angle than that of gamma p --> K+ Sigma0. The Sigma+ is polarized predominantly at cos(Theta_K^{c.m.}) \approx 0. The data presented here are more precise than previous ones obtained with SAPHIR and extend the photon energy range to higher values. They are compared to isobar model calculations.

description: The paper bases itself on recent theoretical writings in growth economics that emphasize the effects of both own R&D efforts and of interregional technology spillovers on regions´ productivity. We propose robust estimation techniques to evaluate the R&D spillovers across West German functional regions during the period 1976 - 1996. The findings suggest the existence of knowledge spillovers across functional regional boundaries. Moreover, significant spillovers are mainly found among geographically close regions. This finding confirms the hypothesis that proximity matters. Das Papier basiert auf jüngeren Beiträgen zur Wachstumstheorie, die den Stellenwert eigener F&E-Anstrengungen und interregionaler Spillover-Effekte für die regionale Produktivitätsentwicklung betonen. F&E-Spillover zwischen funktionalen Regionen in Westdeutschland werden auf der Grundlage robuster Regressionsmethoden für den Zeitraum zwischen 1976 und 1996 untersucht. Die empirischen Ergebnisse deuten darauf hin, dass Wissensspillover die Grenzen funktionaler Regionen überschreiten. Zudem sind signifikante Spillover-Effekte vor allem zwischen räumlich benachbarten Gebieten festzustellen. Dieses Resultat bestätigt die Hypothese, dass räumliche Nähe von we- sentlicher Bedeutung ist.
Investigation of hydrological and geochemical properties and spatial relationships of an unsaturated waste rock pile, Key Lake, Saskatchewan

Year: 2009

description: Controls on environmental loading from acid mine drainage (ARD) are not well understood in waste rock material. In particular, relationships between subsurface flow and the timing, duration, and intensity of leaching of metals and acidity from waste rock dumps remain ill defined. This study investigates field-scale relationships between subsurface flow processes and geochemical processes in unsaturated waste rock. A 12-meter tall, unsaturated waste rock pile, constructed in 1994, was deconstructed and sampled at Key Lake, Saskatchewan, Canada, during the summer of 2000. A detailed sampling methodology was developed to characterize physical and chemical properties of waste rock material within the waste rock pile. Physical properties were characterized by measuring soil-water suction, volumetric water content, and grain-size distribution at 60 random and 20 grid locations within the pile. Paste pH, pore-water geochemistry, mineralogy, and analyses of selective extractions were used as metrics characterizing geochemical processes and sulfide oxidation at each of the 20 grid locations. Attempts to develop a field-based soil water characteristic curve failed due to spatial variability and hysteresis of waste rock properties. Grain-size distribution was used as a relative measure of subsurface flow. Geochemical characterization results demonstrate the preferential weathering of marcasite relative to pyrite and chalcopyrite. Dolomite is the main buffering carbonate mineral. Gyspum, jarosite and iron oxides are the main secondary minerals. Pore-waters contain up to 800, 11.7, and 6 mMolar (78,000, 690, 1400 mg/1) of sulfate, nickel, and uranium, respectively, suggesting significant weathering is occuring. Weathering rates calculated from estimating secondary mineral accumulation range from 0.3 - 49 and 0.8 - 61 M/kg/week for sulfate and iron release rates, respectively. Measures of weathering indicators show no discernable correlation with grain-size distribution nor do they show any spatial relationship within the sampled grid. Reasons for this may include limited duration of waste rock exposure to weathering and development of fluid flow-paths, and limitations of characterization methods used. Indeed, six years may not be long enough for weathering patterns to develop due to fluid flow-paths in this unsaturated waste rock pile.

description: Non-Abelian quantum holonomies, i.e., unitary state changes solely induced by geometric properties of a quantum system, have been much under focus in the physics community as generalizations of the Abelian Berry phase. Apart from being a general phenomenon displayed in various subfields of quantum physics, the use of holonomies has lately been suggested as a robust technique to obtain quantum gates; the building blocks of quantum computers. Non-Abelian holonomies are usually associated with cyclic changes of quantum systems, but here we consider a generalization to noncyclic evolutions. We argue that this open-path holonomy can be used to construct quantum gates. We also show that a structure of partially defined holonomies emerges from the open-path holonomy. This structure has no counterpart in the Abelian setting. We illustrate the general ideas using an example that may be accessible to tests in various physical systems.

description: Currently, the EU-15 forms the only bubble under the Kyoto Protocol and has negotiated an internal burden sharing. A strategic EU climate policy should include accession countries. Thus, even in the case of early ratification of the Kyoto Protocol by 2002, it would be sensible to form a bubble with all countries that are certain to be EU members during the commitment period 2008-2012. Of course due to Art. 4,4 of the Protocol the EU-15 has to stick to its own bubble. However, nothing prevents it from forming an implicit bubble including all first wave countries by inducing them to form a bubble on their own and transfer the surplus to the EU-15. Similarly, second wave countries should form a bubble of their own to co-ordinate JI and permit transfers to the EU. This would reduce the gap between business-as-usual and the target by about 50%. If ratification is delayed to a point where it is clear which second wave countries will be members by 2008, the bubble should be extended by those countries. When in 2005 target negotiations start for the second commitment period, the EU should negotiate a bubble consisting of all states being certain to be members by 2013. Derzeit ist die EU der 15 die einzige Emissionsgemeinschaft nach den Regeln des Kyoto-Protokolls und hat eine interne Lastenteilung vereinbart. Eine strategische EUKlimapolitik sollte die Beitrittsländer einschließen. Selbst im Fall einer frühzeitigen Ratifizierung des Kyoto-Protokolls wäre es sinnvoll, eine Emissionsgemeinschaft mit allen Ländern abzuschließen, die in der Zielperiode 2008-2012 EU-Mitgliedsländer sein werden. Aufgrund Art. 4,4 des Protokolls muss die EU der 15 ihre Emissionsgemeinschaft aufrechterhalten. Jedoch hindert sie nichts daran, eine implizite Emissionsgemeinschaft mit den Ländern der ersten Beitrittswelle zu bilden, indem diese eine eigene Gemeinschaft bilden und den Überschuß an die EU der 15 weitergeben. Gleichermaßen sollten auch die Länder der zweiten Beitrittswelle eine Gemeinschaft bilden, um ihre Transfers an die EU abzustimmen. Dies würde den Abstand zwischen "weiter so" und dem Kyoto-Ziel um ca. die Hälfte verringern. Wenn die Ratifizierung so lange verzögert wird, daß klar ist, welche Länder der zweiten Welle 2008 EUMitglied sein werden, sollte die Gemeinschaft entsprechend erweitert werden. Bei den 2005 beginnenden Verhandlungen über Ziele für die zweite Budgetperiode sollte die EU eine Zielgemeinschaft für alle Länder anstreben, die 2013 sicher EU-Mitglied sein werden.

description: We report on the bright Lyman-break galaxies (LBGs) selected in a 767 arcmin^2 area of the Subaru Deep Field. The selection is made in the i-zR vs zB-zR plane, where zB and zR are new bandpasses with a central wavelength of 8842A and 9841A, respectively. This set of bandpasses enables us to separate well z~6 LBGs from foreground galaxies and Galactic cool stars. We detect 12 LBG candidates down to zR=25.4, and calculate the normalization of the rest-frame far-ultraviolet (FUV: 1400A) luminosity function at MFUV = -21.6 to be ϕ(-21.6) = (2.6+/-0.7) x 10^{-5} mag^{-1} Mpc^{-3}. This must be the most reliable measurement ever obtained of the number density of bright z~6 LBGs, because it is more robust against both contamination and cosmic variance than previous values. The FUV luminosity density contributed from LBGs brighter than MFUV = -21.3 is (2.8+/-0.8) x 10^{24} ergs/s/Hz/Mpc^3, which is equivalent to a star formation rate density of (3.5+/-1.0) x 10^{-4} Msun/yr/Mpc^3. Combining our measurement with those at z<6 in the literature, we find that the FUV luminosity density of bright galaxies increases by an order of magnitude from z~6 to z~3 and then drops by 10^3 from z~3 to the present epoch, while the evolution of the total luminosity density is much milder. The evolutionary behavior of bright LBGs resembles that of luminous dusty star-forming galaxies and bright QSOs. The redshift of z~3 appears to be a remarkable era in the cosmic history when massive galaxies were being intensively formed.

description: Owing to their advantageous characteristics, natural dyes are highly needed to replace hazardous synthetic colored molecules. In this work, an aqueous extract of Citrullus colocynthis leaves was prepared, analyzed using Fourier Transform Infrared (FT-IR) spectroscopy and High-Pressure Liquid Chromatography/Mass Spectrometry (LC-MS/MS), and further used to dye cotton fibers. FT-IR results suggested that the studied Citrullus colocynthis leaf is possibly rich in phenolic and flavonoid constituents. The dyeing experiments were carried out at various experimental conditions: dyeing duration (30–60 min), temperature (60–100°C), and pH (5–9). Response surface methodology (RSM), with the help of Minitab 17.1.0, was used to optimize the dyeing process. The optimum obtained dyeing conditions were time = 30 min, temperature = 91°C, and pH = 7. The cationization of cotton fabric with polyethyleneimine and a co-polymer of dimethyl diallyl ammonium chloride and diallylamin, and the pre-biomordanting with pomegranate peel and date palm pits significantly improved the color strength (K/S) results. Overall, the dyed cotton samples exhibited good fastness characteristics.
Nachhaltige Entwicklung in Gemeinden durch Solidarische Landwirtschaft: Ein Praxisbeispiel aus Yverdon-les-Bains und dessen Bedeutung für das Berufsfeld der Soziokulturellen Animation

description: Die vorliegende Forschungsarbeit von Jessica Brenzikofer und Sebastian von Fischer hat zum Ziel, Antworten auf die Frage zu finden, wie sich die Soziokulturelle Animation an der Förderung von Nachhaltiger Entwicklung in Gemeinden beteiligen kann. Die schweizerische Nachhaltigkeitsstrategie, zu welcher die Gemeinden durch das Subsidiaritätsprinzip verpflichtet sind, bietet die Grundlage der Argumentation, weshalb zukunftsfähige Projekte gefördert werden müssen. Die alternative Produktionsform der Solidarischen Landwirtschaft strebt Wirkungen an, welche sich mit den Zielsetzungen der schweizerischen Nachhaltigkeitsstrategie decken. Daraus lassen sich Ansätze für die Umsetzung der Nachhaltigkeitsziele auf Gemeindeebene ableiten. Für die Professionellen der Soziokulturellen Animation, als Brückenbauende zwischen Zivilgesellschaft und Gemeindestruktur, zeichnet sich dabei ein Handlungsfeld ab, in welchem ein Beitrag zu einer zukunftsfähigen Gesellschaft geleistet werden kann. Anhand eines von der Gemeinde initiierten Solawi-Projekts, wurden Parallelen zur Arbeitsweise der Soziokulturellen Animation gezogen und konkrete Vorteile aufgezeigt, welche aus der soziokulturellen Begleitung zivilgesellschaftlicher Projekte hervorgehen können. Abschliessend werden Schlussfolgerungen für das Berufsfeld der Soziokulturellen Animation in Bezug auf die Arbeit in Gemeinden und auf die Umsetzung der Nachhaltigen Entwicklung in der Profession gezogen. Diese deuten darauf hin, dass sich die Soziokulturelle Animation vermehrt für eine Nachhaltige Entwicklung einsetzen sollte, da sich deren Ziele mit ihrem Berufsethos in weiten Bereichen deckt.

Permanence of CDM Forests or Non-permanence of Land Use Related Carbon Credits?

description: Carbon sequestration projects in the context of the Clean Development Mechanism (CDM) suffer from the stigma of permanence risk. The risk that carbon reduced or sequestered in forestry projects is release further down the road is in fact undeniable, whoever bears the onus. The merit of the so-called "ton/year approach" is to destroy the fiction of infinity when talking about permanent sequestration. The merit of the "Columbian proposal" is to destroy the fiction of comparability between technological emission reduction and sequestration in natural systems. Yet, both approaches are discussed as more or less unrelated alternatives. By making use of both methodologies and providing a link between both proposals on permanence in CDM forestry, the present article puts forward the proposal of leasing reduction certificates.

description: We report the discovery of a debris system associated with the $\sim 30$ Myr old G3/5V star HD 12039 using {\it Spitzer Space Telescope} observations from 3.6 -- 160$μ$m. An observed infrared excess (L$_{\rm IR}$/L$_{\ast} = 1\times10^{-4}$) above the expected photosphere for $λ\gtrsim 14μ$m is fit by thermally emitting material with a color temperature of T$\sim 110$ K, warmer than the majority of debris disks identified to date around Sun-like stars. The object is not detected at 70$μ$m with a 3$σ$ upper limit 6 times the expected photospheric flux. The spectrum of the infrared excess can be explained by warm, optically thin material comprised of blackbody-like grains of size $\gtrsim 7 μ$m that reside in a belt orbiting the star at 4--6 AU. An alternate model dominated by smaller grains, near the blow-out size $a\sim 0.5μ$m, located at 30-40AU is also possible, but requires the dust to have been produced recently since such small grains will be expelled from the system by radiation pressure in $\sim$ few $\times 10^{2}$yrs.

description: The Clean Development Mechanism (CDM) was originally seen as an instrument with a bilateral character where an entity from an industrialised country invests in a project in a developing country (DC). Also, multilateral funds were envisaged that would bundle investments to spread project risks. The sluggish implementation of incentives for industrialised country companies to embark on CDM projects and low carbon prices led to a preference of just buying Certified Emission Reductions (CERs) instead of investing in projects. Thus a third option has gained prominence - the unilateral option where the project development is planned and financed within the DC. We propose that a project should be called "pure unilateral" if it involves no foreign direct investment (FDI), only has the approval of the Designated National Authority (DNA) of the host country and sells its CERs after certification directly to an industrialised country. Unilateral projects can become attractive if the host country risk premium for foreign investors is high despite a high human, institutional and infrastructure capacity and domestic capital availability. Moreover, transaction costs can be reduced compared to foreign investments that have to overcome bureaucratic hurdles. On the other hand, technology transfer is likely to be lower, capacity building has to be done by the host country and all risks have to be carried by host country entities. The potential to carry out unilateral CDM projects strongly varies among DCs. Whereas several countries from Asia and Latin America might well be able to design projects autonomously, most of the Sub-Saharan countries rely on foreign support. International donors of capacity building grants should increasingly address those DCs that are not in the focus of foreign investors and support them in the design of projects.
