description: We have observed the Fano-Kondo anti-resonance in a quantum wire with a side-coupled quantum dot. In a weak coupling regime, dips due to the Fano effect appeared. As the coupling strength increased, conductance in the regions between the dips decreased alternately. From the temperature dependence and the response to the magnetic field, we conclude that the conductance reduction is due to the Fano-Kondo anti-resonance. At a Kondo valley with the Fano parameter $q\approx 0$, the phase shift is locked to $π/2$ against the gate voltage when the system is close to the unitary limit in agreement with theoretical predictions by Gerland {\it et al.} [Phys. Rev. Lett. {\bf 84}, 3710 (2000)].

description: Magyarországon a bárányhizlalás az utóbbi nyolc évben általában veszteséges volt, és csak két súlykategóriában – 24-27 kg és 27-30 kg – volt érdemes értékesíteni, mert itt az évek többségében eltérő mértékű, de szerény jövedelem keletkezett. A 20-24 kg-os kategóriában értékesített bárányok csak nyújtott szoptatással eredményeznek jövedelmet. Abban az esetben, ha a bárányt 16-20 kg-osan választják el, és hizlalják, veszteséget érnek el. A kosbárányok hizlalásának jövedelme magasabb és biztosabb, mint a jerkebárányoké. A magyarországi bárányhizlalás jövedelme az értékesítési árak nagy változékonysága, és a piac bizonytalansága miatt kockázatos. A két ivar jövedelmét együttesen vizsgálva, azt mondhatjuk, hogy a nyári hizlalási időszakban érhető el a legkedvezőbb jövedelem, míg ha csak a kosok eredményeit vesszük figyelembe, akkor az őszi és a tavaszi időszak jövedelme a legmagasabb, azaz a húsvéti és a karácsonyi szezon kiemelkedő. Az eredmények alapján a jerkéket kissúlyban, a kosokat pedig hizlalva, nagyobb súlykategóriában ajánlatos értékesíteni a piacokon. ------------------------------------------------------ In Hungary lamb rearing in the last eight years was generally a loss making activity. Marketing was worthwhile only in two weight categories, 24-27kg and 27-30kg where in most years variable although modest profits were made. Lambs in the 20-24kg categories make profit only if they are subjected to prolonged suckling. If lambs of 16-20kg weight separated from their mothers are fattened they make a loss. Income from rearing of ram lamb is higher and more secure than that of ewe lamb. Rearing lamb in this country is on the whole a risky business because of highly variable selling prices and insecure markets. Taking both genders together, income from summer rearing is the most favourable, but taking male lambs separately autumn and spring rearing is the most profitable, peaking at Easter and Christmas time. On the basis of this investigation ewe lambs should be marketed at low body weight whereas ram labs can be profitable sold in higher weight categories.

Political Will for Anti-Corruption Reform: The Weight of Political Context in the Making of a National Anti-Corruption Plan in Peru

description: Regardless of the progress made in the past two decades by the international anti-corruption movement in terms of its financial, technical, and human resources, the implementation of effective policies by national governments have rarely been in line with their discursive and legal commitments. Furthermore, literary progress on the subject has been hard pressed to find feasible solutions to the lack of political will hindering the adoption of domestic anti-corruption reforms. The present study addresses this issue by reinterpreting the meaning of political will for domestic anti-corruption activities, positing that anti-corruption, contrary to most other types of policies, cannot be stimulated solely by the promise of political support for reformist leaders: rather, it responds to the leadership’s calculus of both political capital and illegal profits. In other words, anti-corruption is only possible when it is appealing to the particular interests of a specific set of political leaders. This approach is tested by assessing the Peruvian experience with the adoption of a National Anti-Corruption Plan between 2001 and 2013. The empirical analysis shows that, contrary to the international emphasis on technical assistance as a vehicle for change, the attempts to adopt a national plan to fight corruption in Peru have closely followed the state and evolution of political events, driven mostly by the necessity to stimulate support for the incumbent party while also kept from affecting the status quo. At the end, the study concludes that the characteristics of the political leadership and context were the primary force behind any symbolic or genuine efforts to elaborate an official National Anti-Corruption Plan, which, notwithstanding its recurrent emergence in the government agenda, has yet to be institutionalized as a proper mechanism to support the fight against public malfeasance.

description: A paradigma fogalmát (a korábbi nyelvészetinél) szélesebb értelemben Thomas Samuel Kuhn amerikai fizikus és tudománytörténész vezette be „A tudományos forradalmak szerkezete” c., 1962-ben megjelent művében. Ezt a könyvet a XX. század legvitatottabb, ugyanakkor szűkebb szakterületén kívül is legismertebb tudományfilozófiai munkájának tartják. Nem véletlen, hogy magyar fordítása is jó néhány kiadásban megjelent. A szerző haláláig (1996) eltelt jó három évtized főként a szűkebb szakmán (tudománytörténeten, tudományfilozófián) belüli megvitatással telt el. Az elmúlt másfél évtizedben azonban megkezdődött a paradigma, illetve a paradigmaváltás fogalmának a különböző tudományokban történő elfogadása és alkalmazása. Az agrárpolitikában négy paradigma különböztethető meg. Tudományos pályán a paradigma rendszerezésre, összehasonlításra, értékelésre serkent, miközben a gazdaságpolitika, így az agrárpolitika átláthatóbbá válik, s változása nyomon követhető, előre jelezhető, elősegítve hipotézisek alkotását. ---------------------------------------------------- The concept of paradigm in a wider sense (wider than the earlier linguistic version) was introduced by Thomas Samuel Kuhn, an American physicist and science historian, in his book on “The structure of scientific revolution” published in c.1962. This book is thought to be one of the most controversial works of the 20th Century and widely held as the best known treatise of scientific philosophy even outside his field of expertise. There was much debate especially in his own field of expertise (science history, scientific philosophy) in the three decades until his death (1996). In the past decade and a half the concept of paradigm or paradigm change has been accepted and applied in various sciences. In agricultural policy four paradigms can be differentiated. In scientific disciplines paradigms encourage systematisation, comparison and evaluation, making economic policy, and thus agricultural policy, increasing more comprehensible, so that changes can be traced, forecast, aiding the formation of hypotheses.
LL-37, a human host defense peptide with immunomodulatory properties
Creators: name: Bowdish, Dawn Marie Edith
Publisher: name: University of British Columbia
Year: 2009

description: Human cationic antimicrobial protein-18 (hCAP-18) is the sole human cathelicidin. It is found at high concentrations in the specific granules of neutrophils, is modestly expressed by epithelial and other cells and can be induced during the course of infection and/or inflammation. The mature, extracellular form of hCAP-18 is termed LL-37, which is a positively-charged, 37-amino acid peptide. Neutrophil-derived host defence peptides were initially discovered as components of the non-oxidative killing mechanisms of neutrophils; however, it is unclear whether LL-37 kills bacteria directly at mucosal surfaces where it is found at lower concentrations. I demonstrated that although LL-37 is antimicrobial in vitro under low salt conditions, it has little or no antimicrobial activity in media containing physiologically relevant cation concentrations. Thus I hypothesised that direct antimicrobial activity was probably not its primary function in vivo at mucosal surfaces. The immunomodulatory properties of LL-37 were investigated in tissue culture media which contains physiological concentrations of cations. When monocytes were treated with LL-37, lipopolysaccharide (LPS)-induced production of proinflammatory cytokines was blocked but TNF-α- induced cytokine production was unaffected and IL-1β-induced cytokine production was enhanced. Consistent with this observation, LL-37 was able to block LPS-induced translocation of the p65 subunit of the pro-inflammatory transcription factor, NF-KB. Other early signalling events mediated by LL-37 included activation of two mitogen-activated protein kinases, p38 and extracellular-regulated kinase. The activation of these kinases was required for IL-8 transcription and release as well as transcription of the chemokines MIP-1α, MIP-1β, and MCP-1. The activation of these kinases and subsequent production and release of IL-8 could be synergistically increased by the presence of granulocyte macrophage-colony stimulating factor, but not related cytokines, indicating that the composition of the inflammatory milieu may affect monocyte responses to LL-37. The data presented here demonstrate that LL-37 is a multi-functional immunomodulator with both pro- and antiinflammatory properties which are maintained at physiological cation concentrations. The observation that LL-37 induced chemokines production suggests that it may recruit leukocytes to sites of infection or inflammation thus providing a possible explanation for the observed antimicrobial properties of this peptide in vivo.

description: As a vital topic in media content interpretation, video anomaly detection (VAD) has made fruitful progress via deep neural network (DNN). However, existing methods usually follow a reconstruction or frame prediction routine. They suffer from two gaps: (1) They cannot localize video activities in a both precise and comprehensive manner. (2) They lack sufficient abilities to utilize high-level semantics and temporal context information. Inspired by frequently-used cloze test in language study, we propose a brand-new VAD solution named Video Event Completion (VEC) to bridge gaps above: First, we propose a novel pipeline to achieve both precise and comprehensive enclosure of video activities. Appearance and motion are exploited as mutually complimentary cues to localize regions of interest (RoIs). A normalized spatio-temporal cube (STC) is built from each RoI as a video event, which lays the foundation of VEC and serves as a basic processing unit. Second, we encourage DNN to capture high-level semantics by solving a visual cloze test. To build such a visual cloze test, a certain patch of STC is erased to yield an incomplete event (IE). The DNN learns to restore the original video event from the IE by inferring the missing patch. Third, to incorporate richer motion dynamics, another DNN is trained to infer erased patches' optical flow. Finally, two ensemble strategies using different types of IE and modalities are proposed to boost VAD performance, so as to fully exploit the temporal context and modality information for VAD. VEC can consistently outperform state-of-the-art methods by a notable margin (typically 1.5%-5% AUROC) on commonly-used VAD benchmarks. Our codes and results can be verified at github.com/yuguangnudt/VEC_VAD.

description: Analytical expressions for calculating the energy density and spatial correlation function of thermal emission by a homogeneous, isothermal sphere of arbitrary size and material are presented. The spectral distribution and the power law governing the distance-dependent energy density are investigated in the near-field and far-field regimes for silicon carbide, silicon and tungsten spheres of various size parameters ranging from X = 0.002 to 5. The spatial coherence of thermal field emitted by spheres is also studied in both radial and polar directions. The energy density follows a power law of d^-2 (d is the observation distance) in the far field for all sizes and materials. The power law in the near field is strongly dependent on the material, size parameter, and the ratio d/a (a is the sphere radius). In the near field, the energy density follows a power law of d^-6 when X<<1 and d/a>>1 (similar to an electric point dipole). With increasing X or decreasing d/a, the contribution of multipoles to the energy density increases resulting in an increase in the power of d until the power law converges to that for a semi-infinite medium. The spatial correlation length in the radial direction is in the orders of $λ$, 0.1$λ$, and 0.001$λ$ in the far field, intermediate near field, and extreme near field, respectively. The correlation angle in the extreme near field is strongly dependent on the sphere size parameter, such that it decreases by three orders of magnitude (from 0.5$π$ to 0.001$π$) when X increases from 0.002 to 5. In the intermediate near field and far field, the correlation angle retains the same order of magnitude (0.15$π$ - 0.7$π$) for all considered Xs. While the excitation of dipolar localized surface phonons (LSPhs) does not affect the correlation length and angle, the multipolar LSPhs reduce the spatial coherence in both directions.

description: Are national leaders really invested in curbing corruption in their countries? The present paper addresses the realpolitik basis of national anti-corruption measures by positing the persistence of a political cost-benefit analysis behind initiatives to curb public malfeasance, which leads to the adoption and implementation of mostly symbolic policies regardless of public discourse. The model is tested by reviewing in detail the adoption and political management of the Peruvian National Anti-Corruption Office between 2007 and 2008. The analysis confirms the theoretical expectations and provides ample evidence of the political instrumentalization of the anti-corruption agenda during the administration of President Alan García Pérez (2006-2011).

description: Excerpts from the report: Because liquid pesticides are a recent development, information on their formulation and distribution is limited. Farmers need to know that through cooperative ownership they can help assure themselves of quality pesticides and related services at reasonable prices. The purpose of this study is to provide information that will be useful to cooperative management in establishing or improving their handling of liquid pesticides. Specifically, the study indicates the services, facilities, formulation and distribution methods, quality control and safety practices, possible problems, and farmer benefits of this type of operation and service.
Resolving the Gibbs phenomenon via a discontinuous basis in a mode solver for open optical systems

description: Partial differential equations are frequently solved using a global basis, such as the Fourier series, due to excellent convergence. However, convergence becomes impaired when discontinuities are present due to the Gibbs phenomenon, negatively impacting simulation speed and possibly generating spurious solutions. We resolve this by supplementing the smooth global basis with an inherently discontinuous basis, incorporating knowledge of the location of the discontinuities. The solution's discontinuities are reproduced with exponential convergence, expediting simulations. The highly constrained discontinuous basis also eliminates the freedom to generate spurious solutions. We employ the combined smooth and discontinuous bases to construct a solver for the modes of a resonator in an open electromagnetic system. These modes can then expand any scattering problem for any source configuration or incidence condition without further numerics, enabling ready access and physical insight into the spatial variation of Green's tensor. Solving for the modes is the most numerically intensive and difficult step of modal expansion methods, so our mode solver overcomes the last major impediment to the use of modal expansion for open systems.

Operationalizing High-Level Corruption Tolerance in Peru: Attitude-Behavior Congruency and the 2006 Presidential Elections

description: Due to the exponential increase in the number and quality of empirical corruption studies spawned from the introduction of quantitative instruments, some necessary theoretical aspects of the phenomenon have somehow fallen behind in the academic agenda. One such example of empirical attention without proper conceptual construction is the case of ‘corruption tolerance’, or the acceptance and support of corrupt activities. The present study sets out to trace the emergence and employment of corruption tolerance as an academic concept, and building on past literature proposes a vertical accountability approach that operationalizes it on behavioral (or action-based) terms as opposed to previous attitude-centered approaches: Citizens must be able to accurately perceive corruption when relevant information is available, adjust their opinions of the involved actors according to that information, and punish in some way the corrupt actors. Failure to reach any of these steps results in the citizen’s behavioral adherence to condone the corrupt behavior of the political actor. To test the extent of the consequences of this departure from attitudes, an empirical indicator of high-level corruption tolerance based on the voting behavior of citizens in the 2006 presidential elections in Peru is constructed, and ordered logistic regression analysis is employed to address the effects of attitudes over behavior regarding high-level corruption. The results show that ‘attitudes’ only marginally affect an individual’s behavior, and hence they can best be understood as one among other determinants of corruption tolerance. This result highlights the necessity to reevaluate the implications for policy implementation of previous studies on the subject.

description: A részletesebb költségvizsgálatok azt mutatják, hogy a mezőgazdasági üzemek között jelentős eltérések találhatók az előállított termékek önköltségében és ágazati eredményében. A differenciák hátterében objektív és szubjektív tényezők húzódnak meg. Napjainkban a szántóföldi növénytermelés legalacsonyabb és legmagasabb önköltsége között 1,5-2-szeres eltérés figyelhető meg. Megállapítható az is, hogy a kedvezőbb önköltségek tartományában kisebbek az átlagtól való eltérések, mint a magasabb önköltségű csoportban. Az állati termékeknél kisebb, 1,4-1,5-szeres az önköltség szóródás a szélső értékek között. Ennek egyik oka, hogy a növények jobban kitettek az időjárási körülményeknek, illetve a termőhelyi adottságoknak. A másik, hogy az állattartásban a rendszerváltástól, és még inkább az EU csatlakozástól kezdve nagyobb szelekció zajlott le, mint a növénytermelésben. ---------------------------------------- Detailed investigation of costs indicated a significant differentiation between production costs and effectiveness of agricultural enterprises. Objective and subjective factors lurk behind the differences. The lowest and highest cost of crop production on arable land varies in these days by a factor of 1.5 to 2. Variation around the mean for units producing at favourable costs is less than for those operating at higher costs. The scatter of costs, ranging by a factor of 1.4 to 1.5, is less for animal products. One reason for this is the fact that plants depend much more than animals on weather conditions and soil characteristics in location. Another reason is that changes in animal keeping since the change of political regime or rather since having joined the EU have been much greater than those in plant production.

description: Setting up a large-scale wireless sensor network is challenging, as firmware must be distributed and trust between sensor nodes and a backend needs to be established. To perform this task efficiently, we propose an approach named Box, which utilizes an intelligent Faraday cage (FC). The FC acquires firmware images and secret keys from a backend, patches the firmware with the keys and deploys those customized images over the air to sensor nodes placed in the FC. Electromagnetic shielding protects this exchange against passive attackers. We place few demands on the sensor node, not requiring additional hardware components or firmware customized by the manufacturer. We describe this novel workflow, implement the Box and a backend system and demonstrate the feasibility of our approach by batch-deploying firmware to multiple commercial off-the-shelf sensor nodes. We conduct a user-study with 31 participants with diverse backgrounds and find, that our approach is both faster and more user-friendly than firmware distribution over a wired connection.

Moreover, by combining these properties with a strong sensitivity of the coupled bands on the surrounding refractive index, we have demonstrated a detection of small refractive index changes in the environment, which is useful for construction of bio-chemical sensors.

Mothers’ experiences with child protection following domestic violence : hear their voices
Creators: name: Anderberg, Marian
Publisher: name: University of British Columbia
Year: 2010

description: This study analyses women's experiences with the child welfare system following episodes of domestic violence. Narratives have been gathered through interviews with three voluntary participants. Two of the women who participated are Aboriginal and the third is an immigrant woman from a South American country. The women described how they were treated by social workers, how their involvement with the child protection system motivated them toward change, and what they experienced while accessing recommended support services. The three mothers provided details of the contact that they had with child welfare services in their interviews. There were three main themes that characterized the mother's stories. These themes were Benefit of the Doubt, Catalyst for Action and The Right Resources. In Benefit of the Doubt, they spoke of how the workers expectations and manner of working with them impacted their lives and feelings of what was happening. They spoke about themselves as mothers and how they wanted social workers to see them in this role. In Catalyst for Action, the mothers spoke about how the involvement of the child welfare system motivated them towards change - either voluntarily or by feeling forced into change. In The Right Resources, they spoke of the services that they accessed and how the provision of supports assisted them. Knowledge of the experiences of mothers gathered directly from their told stories provides direction to the field of child protection.

Az elemi károkból adódó veszteség pótlását nem csupán a gazdálkodónak kellene viselni. Az állami szerepvállalásnak újra be kellene kapcsolódnia a rendszerbe, ha nem is közvetlen díjtámogatás formájában, hanem kiegészítő biztosítás nyújtásával, a biztosító társaságok kártalanítása mellett. -------------------------------------------------- On the basis of our investigations we determined that the insurance profession has developed a process for loss estimation and adjustment for those engaged in agricultural activities and offers a wide range of individual constructions, despite which, the proportion of agricultural insurance within the total insurance market can be said to be minimal. The main reason for this is the termination of subsidies designed to motivate insurance. The low levels of income in farming, however, cannot bear even the relatively small insurance fees. Compensation for losses caused by natural disasters should not, however, be borne solely by farmers. The State should once again take on a role in the system, not necessarily in the form of direct fee subsidies, rather by offering supplementary insurance alongside the insurance companies’ indemnification.

description: The extra stiffness that the magnetic field adds to the ISM changes the way it reacts to the presence of a spiral perturbation. At intermediate to high z, the gas shoots up before the arm, flows over, and falls behind it, as it approaches the next arm. This generates a multicell circulation pattern, within each of which the net radial mass flux is positive near the midplane and negative at higher z. The flow distorts the magnetic field lines. In the arm region, the gas flows nearly parallel to the arm, and therefore, the magnetic field adopts a similar pitch angle. Between the arms, the gas flows out in radius, generating a negative pitch angle in the magnetic field. The intensity and direction of the field yield synthetic synchrotron maps that reproduce some features of the synchrotron maps of external galaxies, like the islands of emission and the displacement between the gaseous and synchrotron arms. When comparing the magnitude of the field with the local gas density, two distinctive relations appear, depending on whether the magnetic pressure is dominant. Above the plane, the density structure develops a shape resembling a breaking wave. This structure collapses and rises again with a period of about 60 Myr, similar to that of a vertical oscillation mode. The falling gas plays an important part in the overall hydrostatics, since its deceleration compresses the low z gas, raising the average midplane pressure in the interarm region above that provided by the weight of the material above.

description: The critical properties of functional materials and nanoscale devices often originate from the coexistence of different thermodynamic phases and / or oxidization states, but sample makeup is seldom completely known a priori. Coherent diffractive imaging (CDI) provides the spatial resolution needed to observe nanoscale coexistence while returning the full amplitude and phase information of an object, but to date lacks the spectral information necessary for composition identification. Here we demonstrate CDI spectroscopy (CDIS), acquiring images of the prototypical quantum material vanadium oxide across the vanadium L2,3 and oxygen K X-ray absorption edges with nanometer scale resolution. Using the hyperspectral X-ray image we show coexistence of multiple oxidization states and phases in a single sample and extract the full complex refractive index of V2O5 and the monoclinic insulating and rutile conducting phases of VO2. These results constrain the role of hidden phases in the insulator-to-metal transition in VO2.

description: We generated synthetic observations from the four-arm model presented in Gomez & Cox (2004) for the Galactic ISM in the presence of a spiral gravitational perturbation. We found that velocity crowding and diffusion have a strong effect in the l-v diagram. The v-b diagram presents structures at the expected spiral arm velocities, that can be explained by the off-the-plane structure of the arms presented in previous papers of this series. Such structures are observed in the Leiden/Dwingeloo HI survey. The rotation curve, as measured from the inside of the modeled galaxy, shows similarities with the observed one for the Milky Way Galaxy, although it has large deviations from the smooth circular rotation corresponding to the background potential. The magnetic field inferred from a synthetic synchrotron map shows a largely circular structure, but with interesting deviations in the midplane due to distortion of the field from circularity in the interarm regions.

description: In this paper, the inclusive Pomeron-Pomeron, Reggeon-Reggeon, Pomeron-Reggeon as well as gluon-Pomeron(-Reggeon) and photon-Pomeron(-Reggeon) interactions for the $\rm η_{c}$ at the LHC energies have been examined in proton-proton, proton-nucleus and nucleus-nucleus collision modes. The cross section has been computed based on the NRQCD factorization and Regge theory formalism. The cross exchange of Pomeron-Reggeon contribution is important in $\rm pp$ and $\rm pA$ modes. The Pomeron-Pomeron contribution is significant in $\rm AA$ mode. The Pomeron contribution is considerable for $\rm AA$ and $\rm pA$ modes in single diffractive process where $\rm A$ undergoes the diffractive process. Reggeon contribution is sizable in $\rm pp$ and $\rm pA$ modes where $\rm p$ only undergoes the diffractive process. The Pomeron and Reggeon contributions in photon-Pomeron and-Reggeon process remain smaller than that of gluon-Pomeron and-Reggeon processes. Our results show that the experimental study of Reggeon, Pomeron and their cross exchange can be carried out in certain kinematic windows with the specific choice of the mode at the LHC. The investigation can be useful to better constrain the Reggeon and Pomeron parton content. The inclusive process serves as the background to related exclusive processes which should be predicted.

description: Coherent phonon generation by optical pump-probe experiments has enabled the study of acoustic properties at the nanoscale in planar heterostructures, plasmonic resonators, micropillars and nanowires. Focalizing both pump and probe on the same spot of the sample is a critical part of pump-probe experiments. This is particularly relevant in the case of small objects. The main practical challenges for the actual implementation of this technique are: stability of the spatio-temporal overlap, reproducibility of the focalization and optical mode matching conditions. In this work, we solve these three challenges for the case of planar and micropillar optophononic cavities. We integrate the studied samples to single mode fibers lifting the need for focusing optics to excite and detect coherent acoustic phonons. The resulting excellent reflectivity contrast of at least 66% achieved in our samples allows us to observe stable coherent phonon signals over at least a full day and signals at extremely low excitation powers of 1uW. The monolithic sample structure is transportable and could provide a means to perform reproducible plug-and-play experiments.

description: We review recent theoretical developments in heavy quarkonium physics from the point of view of Effective Field Theories of QCD. We discuss Non-Relativistic QCD and concentrate on potential Non-Relativistic QCD. Our main goal will be to derive QCD Schrödinger-like equations that govern the heavy quarkonium physics in the weak and strong coupling regime. We also discuss a selected set of applications, which include spectroscopy, inclusive decays and electromagnetic threshold production.

The Cryogenic Refractive Indices of S-FTM16, a Unique Optical Glass for Near-Infrared Instruments

description: The Ohara glass S-FTM16 is of considerable interest for near-infrared optical designs because it transmits well through the K band and because negative S-FTM16 elements can be used to accurately achromatize positive calcium fluoride elements in refractive collimators and cameras. Glass manufacturers have sophisticated equipment to measure the refractive index at room temperature, but cannot typically measure the refractive index at cryogenic temperatures. Near-infrared optics, however, are operated at cryogenic temperatures to reduce thermal background. Thus we need to know the temperature dependence of S-FTM16's refractive index. We report here our measurements of the thermal dependence of S-FTM16's refractive index between room temperature and ~77 K. Within our measurement errors we find no evidence for a wavelength dependence or a nonlinear temperature term so our series of measurements can be reduced to a single number. We find that Delta n_{abs} / Delta T = -2.4x10^{-6} K^{-1} between 298 K and ~77 K and in the wavelength range 0.6 micron to 2.6 micron. We estimate that the systematic error (which dominates the measurement error) in our measurement is 10%, sufficiently low for most purposes. We also find the integrated linear thermal expansion of S-FTM16 between 298 K and 77 K is -0.00167 m m^{-1}.

description: A pesar del progreso hecho en las últimas dos décadas, los actuales esfuerzos anticorrupción continúan luchando con problemas de implementación en determinados países. El presente estudio propone una aproximación a la implementación de políticas anticorrupción que considera la lucha contra las inconductas públicas en términos de sus posibles costos y beneficios en el liderazgo político. La existencia de un ciclo político para las iniciativas anticorrupción se propone y se prueba a través de un examen de la Comisión Nacional Anticorrupción de Perú entre los años 2001 y 2005. El análisis empírico respalda los principios teóricos, demostrando cómo el gobierno del Presidente Alejandro Toledo creó y luego retrocedió con la comisión anticorrupción, dados los intereses privados y las circunstancias políticas.
