description: The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them to those best able to implement them (technology transfer). But frictions in this market, including search, bargaining, and commitment problems, impede exchange and thus slow growth. We characterize optimal policies to subsidize research and trade in ideas, given both knowledge and search externalities. We discuss the roles of liquidity and financial institutions, and show two ways in which intermediation can enhance efficiency and innovation. First, intermediation allows us to finance more transactions with fewer assets. Second, it ameliorates certain bargaining problems, by allowing entrepreneurs to undo otherwise sunk investments in liquidity. We also discuss some evidence, suggesting that technology transfer is a significant source of innovation and showing how it is affected by credit considerations.
description: La création et la réalisation d’idées – le savoir – sont cruciales pour l’économie. Les auteurs étudient ce processus à l’aide d’un modèle de croissance endogène intégrant des frictions. La productivité augmente avec le savoir, qui s’accroît grâce à l’innovation, et avec l’échange s’établissant entre les créateurs d’idées et les agents les plus aptes à les faire aboutir (transfert de technologie). Sur ce marché des idées existent toutefois des frictions – concernant par exemple la prospection, la négociation et la prise d’engagements – qui entravent l’échange et freinent donc la croissance. Tenant compte des externalités du savoir et de l’activité de prospection, les auteurs décrivent des politiques optimales pour subventionner la recherche et vendre les idées. Ils analysent les rôles joués par la liquidité et les institutions financières et dégagent deux voies par lesquelles l’intermédiation peut améliorer l’efficience de même que l’innovation. Tout d’abord, l’intermédiation permet de financer un nombre accru de transactions à partir d’un nombre réduit d’actifs. Ensuite, elle atténue certains problèmes de négociation en fournissant aux entrepreneurs une solution de rechange à la détention de liquidités non rémunérées. Les auteurs examinent aussi des données, dont certaines paraissent indiquer que les transferts de technologies sont une importante source d’innovation, et montrent comment les imperfections du crédit gênent le processus d’innovation.

description: We report on the identification of the optical and infrared counterparts of the ultraluminous X-ray source (ULX) XMMU J121214.5+131248 (NGC4168-ULX1). The optical spectrum yields a redshift of z=0.217, which implies that the ULX is not associated with the nearby galaxy NGC 4168, but rather with a background object. Optical spectral line ratios and the spectral energy distribution constructed from the available data indicate that the source is likely a starburst nucleus.

 The primary reservoirs present in the Southern Chotts Basin, Central Tunisia, are located within Triassic-, Permian- and Ordovician units. They are mainly sourced by the Silurian - Lower Devonian Fegaguira Fm. and its Hot Shale member. The Hercynian Orogeny has reworked the Palaeozoic package, removing the Devonian - Carboniferous and most of the Permian deposits in the Southern Chotts Basin. This resulted in a diachronous unconformity in the present-day stratigraphy. Constraining estimated sediment deposition and subsequent erosion at unconformities is crucial to predict timing of source rock maturation. This study aims to qualify and quantify the effects of several simplified burial- and thermal histories on the timing of source rock maturation, understand migration pathways to predict sweet spots and gain insight in Mesozoic burial. Thermal history calibration was performed and allowed modelling source rock maturation in the basin's kitchen area. Hydrocarbon generation occurs in two phases separated by a phase of stable maturity during Hercynian exhumation. Pre-Hercynian generation is unlikely to result in preserved accumulations in post-Hercynian traps. Renewed maturation in Jurassic - Cretaceous times likely sources present-day hydrocarbon accumulations in post-Hercynian traps. The number of phases- and maximum burial depth associated with the Hercynian Orogeny determine the amount of missed pre-Hercynian hydrocarbons and the timing of renewed maturation in the Mesozoic. Sensitivity analysis on estimated Hercynian erosion further constrained associated maximum burial and -hydrocarbon generation. 2D basin modelling captures migration pathways and helped predicting sweet spots. Subsidence analysis shows Mesozoic subsidence occurs as a result of pulsed rifting with possible short-lived uplift phases, indicating the diachronous nature of tectonics in the Southern Chotts Basin.

Modelling of subsurface temperatures is based on various approaches, which typically focus on interpolation or numerical simulation procedures. Mostly, they are based on few single measurements and do not take into account the geological structure or lithological and thermal conductivity conditions of the subsurface. Herein, we present a new approach for the parameterization and modelling of subsurface temperatures for areas with sparse available data. We used temperature log measurements from 26 spatially distributed boreholes drilled by oil and gas exploration companies.

description: Even with today’s technically advanced navigation systems, user experience situations where announcements are difficult to understand and misleading. Augmented reality – the integration of computer generated content into the vehicle surrounding – can provide an intuitive and unambiguous way to communicate navigation information; it can even serve as a novel user interface that allows interaction with the surrounding. In this paper, challenges, constraints, and possible solutions for AR in-vehicle applications are discussed. Details of the technical and design decisions of the “first in-vehicle augmented video system” are explained, as well as features and possible future upgrades.

description: We present results from three world-wide campaigns that resulted in the detections of two single-chord and one multi-chord stellar occultations by the Plutino object (84922) 2003~VS$_2$. From the single-chord occultations in 2013 and 2014 we obtained accurate astrometric positions for the object, while from the multi-chord occultation on November 7th, 2014, we obtained the parameters of the best-fitting ellipse to the limb of the body at the time of occultation. We also obtained short-term photometry data for the body in order to derive its rotational phase during the occultation. The rotational light curve present a peak-to-peak amplitude of 0.141 $\pm$ 0.009 mag. This allows us to reconstruct the three-dimensional shape of the body, with principal semi-axes $a = 313.8 \pm 7.1$ km, $b = 265.5^{+8.8}_{-9.8}$ km, and $c = 247.3^{+26.6}_{-43.6}$ km, which is not consistent with a Jacobi triaxial equilibrium figure. The derived spherical volume equivalent diameter of $548.3 ^{+29.5}_{-44.6}$ km is about 5\% larger than the radiometric diameter of 2003~VS$_2$ derived from Herschel data of $523 \pm 35$ km, but still compatible with it within error bars. From those results we can also derive the geometric albedo ($0.123 ^{+0.015}_{-0.014}$) and, under the assumption that the object is a Maclaurin spheroid, the density $ρ= 1400^{+1000}_{-300}$ for the plutino. The disappearances and reappearances of the star during the occultations do not show any compelling evidence for a global atmosphere considering a pressure upper limit of about 1 microbar for a pure nitrogen atmosphere, nor secondary features (e.g. rings or satellite) around the main body.

description: Smallholder farmers are heterogeneous in terms of resource endowments, production orientation and access to markets. An understanding of these factors and how they influence local perceptions and responsiveness to climate variability has potential to improve the livelihoods of smallholder farmers. The objective of this study was to understand the major factors that contribute to heterogeneity across households and across sites and to understand how different households respond to climate variability induced hazards. Cross-sectional data was collected using a household questionnaire from 300 randomly selected households from Seke and Murewa districts in Zimbabwe but only 299 questionnaires were used for analysis. Principal component analysis was used to identify uncorrelated factors. The multinomial logit model was used to determine the influence of household characteristics on farmers’ perceptions and logit model was used to ascertain the influence of socioeconomic factors and perceptions on responsiveness. Findings showed that households that are heterogeneous in religion; direct personal experiences; and access to weather information have different perceptions to climate variability induced hazards. Empirical results from multinomial regression analysis showed that socioeconomic factors such as distance to the market and access to credit information have a significant influence on perceptions but human capital-related and gender-related characteristics have an insignificant influence on farmers’ perceptions. Econometric investigation using logistic regression model revealed that socioeconomic factors have an influence on responsiveness but perceptions do not influence responsiveness; this could be so because there are other underlying factors related to adaptive capacity which are limiting farmers in responding to hazards. The overall conclusion is that differences in access to markets and credit result in heterogeneity in farmers’ perceptions. In terms of policy implications this means that improvement of access to markets and credit is very crucial to improve farmers’ responsiveness to climate variability induced hazards.

description: We propose a one-dimensional nonlocal stochastic model of adsorption and desorption depending on one parameter, the adsorption rate. At a special value of this parameter, the model has some interesting features. For example, the spectrum is given by conformal field theory, and the stationary non-equilibrium probability distribution is given by the two-dimensional equilibrium distribution of the ice model with domain wall type boundary conditions. This connection is used to find exact analytic expressions for several quantities of the stochastic model. Vice versa, some understanding of the ice model with domain wall type boundary conditions can be obtained by the study of the stochastic model. At the special point we study several properties of the model, such as the height fluctuations as well as cluster and avalanche distributions. The latter has a long tail which shows that the model exhibits self organized criticality. We also find in the stationary state a special phase transition without enhancement and with a crossover exponent $ϕ=2/3$. Furthermore, we study the phase diagram of the model as a function of the adsorption rate and find two massive phases and a scale invariant phase where conformal invariance is broken.

 Heterocerus auromicans Kiesenwetter 1851: 287.
 Centuriatus auromicans (Kiesenwetter): Pacheco 1964: 30.
 Description. Length 3.5 - 5.5 mm. Reddish-brown. Pronotal disk with a pale midline, about one-eighth the width of the pronotum (Fig. 30). Elytra trifasciate; pale elytral markings orange and distinct. Postmetathoracic coxal lines and post-mesothoracic coxal lines prominent. Male genitalia (Fig. 51) of the typical Augyles type; phallobase slightly expanded anteriorly; medial edges of caliper-like parameres separated by an ovoid space; a dark, membranous internal structure (presumably the aedeagus) is often curled within the anterior end. Hypermandibulate males unknown.
 Diagnosis. The presence of post-metathoracic coxal lines and a median pale stripe on the pronotum make this species easy to distinguished from all other southeastern heterocerids.
 Notes. Aggregations of A. auromicans form mud galleries that are smaller and more scattered than those made by H. pallidus (Kaufmann 1987). This apparently leads to less frequent mating encounters, and consequently, male priority (the last male to mate with a female fertilizes nearly all of the eggs). Spermatogenesis is constant in A. auromicans, in contrast to H. pallidus where spermatogenesis is affected by weather patterns. Augyles auromicans also flies less often as a response to agitation than H. pallidus, usually choosing to dig deeper into the substrate rather than taking flight (Kaufmann 1987).
The species has not been found in Mississippi, and only one specimen is known from Alabama. This specimen was collected from a swampy area near Tuscaloosa (Tuscaloosa County, 5 mi. SW Tuscaloosa, 18 April 1981, S.C. Harris), which has since undergone development.
 Distribution. Augyles auromicans occurs from southern British Columbia southeast to Colorado and east throughout the northern United States to the Atlantic Coast. Records from the northern U.S. and southern Canada are common; however, A. auromicans has rarely been collected in the southern states (Fig. 70).
 Specimens examined. 8 (See Appendix).

description: We combine ab initio, tight-binding methods and analytical theory to study piezoelectric effect of boron nitride nanotubes. We find that piezoelectricity of a heteropolar nanotube depends on its chirality and diameter and can be understood starting from the piezoelectric response of an isolated planar sheet, along with a structure specific mapping from the sheet onto the tube surface. We demonstrate that coupling between the uniaxial and shear deformation are only allowed in the nanotubes with lower chiral symmetry. Our study shows that piezoelectricity of nanotubes is fundamentally different from its counterpart in three dimensional (3D) bulk materials.

description: Current theories and models attempt to explain star formation globally, from core scales to giant molecular cloud scales. A multi-scale observational characterisation of an entire molecular complex is necessary to constrain them. We investigate star formation in G202.3+2.5, a ~10x3 pc sub-region of the Monoceros OB1 cloud with a complex morphology harbouring interconnected filamentary structures. We aim to connect the evolution of cores and filaments in G202.3+2.5 with the global evolution of the cloud and to identify the engines of the cloud dynamics. In this first paper, the star formation activity is evaluated by surveying the distributions of dense cores and protostars, and their evolutionary state, as characterised using both infrared observations from the Herschel and WISE telescopes and molecular line observations with the IRAM 30-m telescope. We find ongoing star formation in the whole cloud, with a local peak in star formation activity around the centre of G202.3+2.5 where a chain of massive cores (10-50 Msun) forms a massive ridge (>150 Msun). All evolutionary stages from starless cores to Class II protostars are found in G202.3+2.5, including a possibly starless, large column density (8x10^{22} cm-2), and massive (52 Msun) core. All the core-scale observables examined in this paper point to an enhanced star formation activity centred on the junction between the three main branches of the ramified structure of G202.3+2.5. This suggests that the increased star-formation activity results from the convergence of these branches. To further investigate the origin of this enhancement, it is now necessary to extend the analysis to larger scales, in order to examine the relationship between cores, filaments and their environment. We address these points through the analysis of the dynamics of G202.3+2.5 in a joint paper.

description: Multiscaling analysis of differential flux dissipation rate of galactic cosmic rays (Carbon nuclei) is performed in the energy ranges: 56.3-73.4 Mev/nucleon and 183.1-198.7 MeV/nucleon, using the data collected by ACE/CRIS spacecraft instrument for 2000 year. The analysis reveals strong (turbulence-like) intermittency of the flux dissipation rate for the short-term intervals: 1-30 hours. It is also found that type of the intermittency can be different in different energy ranges.
Economics of Fertilizer Utilization in Small-Scale Farming Systems and Appropriate Role for Policy

description: Upholding increased adoption and utilization of superior agricultural technologies such as inorganic fertilizers has become the panacea and the real option to revitalize the agricultural sector in Zimbabwe. This research study focuses on the supply side issues determining the demand of the inorganic fertilizers by small-scale farming communities. The main objective is to carry out a comparative institutional performance evaluation of the government of Zimbabwe’s fertilizer input support and the private input supply systems. It is argued that the fertilizer marketing channel used by small-scale farmers to obtain the input plays a critical role in influencing the utilization of the input and subsequent performance of the farming community. A survey was administered to 200 farmers randomly selected in Mashonaland Central Province. Tobit, Probit and Logistical Regression Models were employed as data analysis tools. Also, the Institutional Analysis and Development Framework was used and key characteristics of the farmers were examined disaggregated by the fertilizer marketing channel used to acquire the input. Performance was measured using crop production and asset ownership variables. The major finding of this study is that untargeted public provision of fertilizer has severely undermined the free market system through the crowding out effect. It has contributed to timeliness failures, operational inefficiencies, growing political interference, heavy reliance on handouts, and availability problems. The study recommends the development of a detailed national fertilizer sub-sector policy that is carefully integrated with a comprehensive agricultural policy. There is need for reconstruction of efficient institutions and new ‘social capital’ that will ensure the proper functioning of fertilizer markets in the countryside. To minimize the exposure to food insecurity of vulnerable segments, government and other development partners are encouraged to make use of non-market distorting interventions such as making the beneficiaries work at public works projects for fertilizer vouchers which are locally redeemable at any of the agro-dealer retail outlets.

description: We examine nine changes in the New York State Security Transaction Taxes (STT) between 1932 and 1981. We find that imposing or increasing an STT results in wider bidask spreads, lower volume, and increased price impact of trades. In contrast to theories of STT imposition as a means to reduce volatility, we find no consistent relationship between the level of an STT and volatility. We examine the propensity of traders to switch trading locations to avoid the tax and find no consistent evidence that they will change locations. We do find evidence to suggest that taxes imposed on the par value of stock will result in corporations managing the par value in the direction of minimizing the impact of the tax on investors.
description: Les auteurs examinent les neuf changements que l’État de New York a apportés à sa taxe sur les transactions de titres entre 1932 et 1981. Ils constatent que l’instauration d’une taxe de ce genre ou sa majoration conduit à un élargissement des écarts entre les cours acheteur et vendeur, à une baisse des volumes ainsi qu’à une augmentation de l’incidence des transactions sur les prix. À l’inverse de ce que prédisent les théories prônant l’imposition d’une taxe sur les transactions afin de réduire la volatilité des marchés financiers, ils n’observent aucun lien systématique entre le niveau de la taxe et celui de la volatilité. Ils se penchent aussi sur la tendance qu’auraient les arbitragistes à se relocaliser pour soustraire leurs transactions à la taxe. Les données ne corroborent pas cette hypothèse. Les auteurs relèvent cependant des indices montrant que l’imposition d’une taxe sur la valeur nominale d’une action incite la société émettrice à gérer cette valeur de manière à minimiser l’effet de la taxe sur les investisseurs.

The post-Variscan nonconformity formed due to the denudation of the Variscan orogen which had taken place between Devonian and early Permian. The widespread post-Variscan nonconformity in central Europe represents an important first-order bounding surface. In this study, the petrological, mineralogical, and geochemical features of the Paleozoic basement, the overlying volcanic and sedimentary rocks from the drill core GA1 on the Sprendlinger Horst, Germany are analyzed by polarizing microscope, SEM (scanning electron microscope), XRD, XRF and ICP-MS.

description: Since its first demonstration in the sixties, coherent anti-Stokes Raman scattering (CARS) has become a powerful spectroscopic sensing tool with broad applications in biology and chemistry. However, it is a complex nonlinear optical process that often leads to the lacks of quantitative data outputs. In this letter, we observe how CARS signal builds up gradually and demonstrate how to control its deferral with laser-pulse shaping. A time-resolved three-color CARS that involves a pair of driving broadband femtosecond pulses and delayed shaped probe pulse is realized experimentally. Driving pulses are tuned to the Raman-resonance onto the vibrational ring modes of pyridine and benzene molecules. As a result, CARS-buildup is deferred in picoseconds as delayed probe pulse width varies from 50 down to 10 cm-1. With off-resonant driving of water molecules this effect, in contrary, does not occur. Laser control predicting deferred resonant processes can serve as a novel and important species-specific indicator in, e.g., machine learning applications for future nonlinear optical spectroscopy.

(Fig. 26, 27, 53, 71)
 Heterocerus pusillus Say 1823: 200.
 Tropicus pusillus (Say): Pacheco 1964: 137.
 Description. Length 2.3 - 3.0 mm. Orange-brown. Elytra orange laterally, with a common brown macula medially (Fig. 26). Males with a process extending from the dorso-lateral edge of each mandible that wraps around the edge of the labrum (Fig. 27), often nearly meeting the process from other side. Postmetathoracic coxal and post-mesothoracic coxal lines absent. Male genitalia (Fig. 53) of the typical Tropicus type, dorsal edge projecting anteriorly.
 Diagnosis. Tropicus pusillus can be easily distinguished from all species of southeastern heterocerid by color pattern alone. The elytra are not trifasciate, as they are in southeastern Heterocerus, but have brown sutural margins. Together, these darker margins produce a rather even-edged median macula on the elytra.
 This coloration also easily distinguishes T. pusillus from its only southeastern congener, Tropicus nigrellus n. sp., which is entirely black.
 Notes. Often the most numerous beetle at a UV light placed near a body of water in the southeastern U.S., T. pusillus is the only species of heterocerid consistently collected from intermittent creek beds, drainage ditches, and sandy ponds. During this project, specimens were collected from the margin of a brackish marshy habitat on the campus of the Gulf Coast Research Laboratory in Ocean Springs, Mississippi.
 Distribution. Tropicus pusillus occurs from near the Canadian border south to Panama and Cuba. It was collected in all 63 Mississippi counties where UV lights were run as part of this project, as well as from most Alabama collection localities sampled by Harris et al. (1991, Fig. 39).
 Specimens examined. 1802 (See Appendix).

title: Portfolio Considerations in Differentiated Product Purchases: An Application to the Japanese Automobile Market
Creators: name: Wakamori, Naoki

description: Consumers often purchase more than one differentiated product, assembling a portfolio, which might potentially affect substitution patterns of demand and, as a consequence, oligopolistic firms’ pricing strategies. This paper studies such consumers’ portfolio considerations by developing a structural model that allows for flexible complementarities/substitutabilities depending on consumer attributes and product characteristics. I estimate the model using Japanese household-level data on automobile purchasing decisions. My estimates suggest that complementarities arise when households purchase a combination of one small automobile and one minivan as their portfolio. Ignoring such effects leads to a overstated counterfactual analysis. Simulation results suggest that a policy proposal of repealing the current tax subsidies for small ecofriendly automobiles would decrease the demand for those automobiles by 9%; less than the 14% drop predicted by a standard single discrete choice model.
description: Les consommateurs acquièrent souvent plusieurs produits différenciés pour les réunir au sein d’un portefeuille. Une telle pratique est susceptible d’influer sur les possibilités de substitution du côté de la demande et, par conséquent, sur les stratégies de prix d’entreprises oligopolistiques. L’auteure examine cette question au moyen d’un modèle structurel où la nature complémentaire ou substituable des biens dépend de leurs caractéristiques ainsi que des attributs des consommateurs. Elle estime le modèle à l’aide de microdonnées relatives aux décisions d’achat d’automobiles des ménages japonais. D’après ses estimations, lorsque le portefeuille du ménage se compose d’une petite voiture et d’une mini-fourgonnette, les deux véhicules ont une fonction complémentaire. Si leur complémentarité n’est pas prise en compte, une analyse contrefactuelle aboutit à des conclusions excessives. La simulation effectuée indique que l’abolition des subventions fiscales accordées à l’achat de petites automobiles respectueuses de l’environnement ferait diminuer de 9 % la demande de ces dernières, plutôt que de 14 % comme le prédit un modèle type de choix discrets portant sur un seul bien.
An Unusual Eclipse of a Pre-Main Sequence Star in IC 348

description: A solar-like pre-main sequence star (TJ 108 = H 187 = LRLL 35 = HMW 15) in the extremely young cluster IC 348 has been found, which apparently experienced an eclipse lasting ~3.5 years, much longer than has ever been detected for any normal eclipsing binary. The light curve is flat-bottomed and rather symmetric, with a depth of 0.66 mag in Cousins I. During eclipse, the system reddened by \~0.17 mag in R-I. We argue that the eclipsing body is not a star because of the small probability of detecting an eclipse in what would be a very widely separated binary. Instead, it appears that the eclipse was caused by a circumstellar or circumbinary cloud or disk feature which occulted the star, or one of its components, if it is a binary system. We emphasize the importance of more detailed study of this object, which appears to be a new member of a small class of pre-main sequence stars whose variability can be firmly linked to occultation by circumstellar (or circumbinary) matter.

Explicit enriched plate model for laminated glass

description: This abstract relates to the recent publication [Viverge K., Boutin C., Sallet F. : Model of highly contrasted plates versus experiments on laminated glass, IJSS, 102-103, 238-258 (2016)]. This contribution provides a synthetic analytic formulation describing the behaviour of laminated glass under static and dynamic loadings, that is validated by experiments. We only give here a synoptic overview and for in depth reading one may refer to the above mentioned publication. As the laminated glass is made of stiff glass layers pasted with soft viscoelastic interlayers a specific model is established to account for the high contrast of mechanical properties. The effective plate model is derived from (i) the constitutive laws of the materials combined with (ii) an asymptotic expansion formulation and (iii) the appropriate scaling of the stiffness contrast. The different regimes of behaviour are clearly specified, according to the mechanical and geometrical parameters of the layers, and to the loading. The analysis evidences the enriched kinematics of highly contrasted plates and yields to an analytic bi-torsor representation that encompasses (i) the shear related to the sliding within the PVB, (ii) the local bending of each glass layer, and (iii) global bending of the whole laminate. Hence, the model can degenerate in either Reissner–Mindlin plate or shear-bending plate model, depending on the parameters of the constituents. In general it results in a tri-Laplacian formulation that help in understanding the behaviour and enables to derive analytical solutions under basic loadings. Furthermore, the theory applies to viscoelastic layers as PVB in laminated glass. This enriched plate model is validated through experiments conducted on two layers laminated glass with viscoelastic PVB interlayers. The theoretical result stating that the principle of time-temperature superposition of the PVB also applies, with the same time factor to the laminated glass, is observed experimentally. In addition, bending creep tests evidence the theoretically predicted transition from the (quasi-) monolithic behaviour at short time to the (quasi-) bi-layers behaviour at long time. The theoretical results describing the influence of both the temperature and frequency are also in good agreement with the experimental data. To conclude, the proposed model provides a simple easy-to-use theoretical framework for engineering purposes. For instance, it allows simple comparisons of the performances - in time and temperature - of laminated glasses made with different polymeric layers. In addition, the presented analytical results are suitable for determining the optimal design of structural elements made of laminated glass. Applications to the assessment or the improvement of the sound attenuation by laminated glass may also be considered.

description: Napier grass stunt disease (NSD) has been a major challenge to sustainable smallholder dairy production in Kenya. A household (HH) survey was conducted using personal interviews to assess the effect of NSD on level of milk production and on milk income at household level in Bungoma District, Western Kenya. Data were collected using structured questionnaires in a cross-sectional survey involving 130 respondents in five selected divisions of the larger Bungoma District. Descriptive statistics were used to assess farmers‟ opinions on the extent of NSD infestation on farms. Cobb Douglas (CD) two stage least square (2SLS) model was used to determine the effects of NSD and other variables on the yield of milk. A log linear regression was used to determine the effects of NSD and other variables on the household milk income. Descriptive results indicate that there was an average drop from two cows to one cow that could be fed on an acre of Napier. The CD 2SLS results show that the area under Napier had a positive significant effect on the area of Napier grass under the NSD. Furthermore, NSD had a significant negative impact on milk yield (p<0.05). Gender, farming experience, and alternative sources of feed were found to have a significant negative influence on milk yield. Prevailing market milk price and number of cattle had a positive influence on milk yield. Napier stunt disease had a significant negative impact on monthly gross margins (GM) per cow (p<0.05). The estimates in Kshs were 4325, 4122, 1433, 2689 and 1782 for Kibabii, Sang‟alo, Bumula, Malakisi and Webuye, respectively. The GM estimates were also influenced by other household characteristics such as HH size, push pull practice, land under Napier grass, milk output, and milk prices all of which had a positive impact. The study provides useful information about the effects of the NSD on small scale dairy production and on specific socioeconomic parameters that farmers, extensionists, researchers and policy makers can use in designing appropriate interventions towards mitigating the negative effects of NSD on overall dairy productivity.

During the current energy transition, understanding our deep subsurface appears more important than ever. Traditional energy resources such as oil and gas might remain dominant in coming years but are also becoming more controversial and more difficult to exploit. With the rising trend of geothermal energy, our geological resources remain pivotal in supplying tomorrows clean energy. With a treasure of subsurface data being gathered in past generations, good access to this data is crucial. However, for many people, including geoscientists, it is not well known what subsurface data is publicly accessible. Moreover, as geology does not stop at boundaries and studies might want to include cross border data, understanding what information is available transnationally is valuable. For this, a full assessment of data access arrangements in several Western European countries ....
