description: Some academics endorse analysing societies’ symbolic forms. This article, therefore, inspects the symbol of door-knocking. It addresses the research question of what impacts data collection through door-knocking. This question was addressed as part of a household survey conducted in low-income Saudi neighbourhoods to study socioeconomics and learning technologies. This study involved recruiting 18 male and female Saudis to knock on 1300 doors. It showed positive and negative influences on data collection. Concerning negative influences, knockers and “knockees” were gendered—constrained by gender separation, societal and parental restrictions upon women and lack of gender confidence. Knockers were intimidated by doors’ assertive features, such as elaborate carvings, decorative cut-outs or colouring. They were frightened by doors’ defensive features, like thick doors with enormous frames, two front doors per house, high concrete walls and unnecessary stairs. They were uncomfortable—exhausted, emotionally distressed and concerned about hygiene and safety. Regarding positive influences, knockers and knockees were traditional, following Saudi negotiation, charity work, hospitality and generosity. Knockees were respectful, showing respect to knockers’ authority, rank and class. They were profit-oriented, appreciating financial and non-financial incentives. Saudi households were distinguishable through food smells, shoes, cars, stickers and plants. These influences constitute methodological grounds for future door-knocking.

description: In-situ measurements of space plasma throughout the solar system require high time resolution to understand the plasma's kinetic fine structure and evolution. In this context, research~is conducted to design instruments with the capability to acquire the plasma velocity distribution and its moments with high cadence. We study a new instrument design, using a constant magnetic field generated by two permanent magnets, to analyze solar wind protons and $α$-particles with high time resolution. We determine the optimal configuration of the instrument in terms of aperture size, sensor position, pixel size and magnetic field strength. We conduct this analysis based on analytical calculations and SIMION simulations of the particle trajectories in our instrument. We evaluate the velocity resolution of the instrument as well as Poisson errors associated with finite counting statistics. Our instrument is able to resolve Maxwellian and $κ$-distributions for both protons and $α$-particles. This method retrieves measurements of the moments (density, bulk speed and temperature) with a relative error below 1%. Our instrument design achieves these results with an acquisition time of only 5 ms, significantly faster than state-of-the-art electrostatic analyzers. Although the instrument only acquires one-dimensional cuts of the distribution function in velocity space, the simplicity and reliability of the presented instrument concept are two key advantages of our new design.

description: In this report we describe an improved method for determining the lattice parameters of a single-crystal sample using the neutron Laue time-of-flight (TOF) technique. The new method enables the measurement of unit cell lattice parameters with uncertainties in the range 0.015 – 0.06%. The method also improves the location, and integration, of weak reflections which are often more difficult to discern amongst the increased background at higher neutron energies. The method employs two related computer programs, SXDCALIB and SXDMEASURE. The first of these is used to calibrate the instrument, and the second used to determine the orientation matrix of an unknown sample, using the calibrated instrument parameters. This report describes how to use SXDMEASURE. SXDCALIB and the calibration procedure will be described in a separate report

description: Делается попытка сопоставить созданные в 1986 году в Ленинграде две футбольные поэмы поэтов-однофамильцев — «Футбол» Олега Григорьева и «День “Зенита”» Геннадия Григорьева. Выявляется, что в лирическом мире Олега Григорьева футбол это сам мир со всеми его нюансами: с героями и злодеями, с прошлым (часто прекрасным) и настоящим (явно уступающим прошлому), с травмами и артистизмом, с трагедиями и кумирами; Олег Григорьев смотрит на футбол и, соответственно, на мир словно сверху, даёт общий план и текущего момента, и истории футбола (и реальной, и мифологической), но вместе с тем, отчётливо воссоздаёт мироощущение человека своей эпохи. Геннадий Григорьев более конкретен — он смотрит словно изнутри: с трибуны, с околостадионного пространства, показывает один конкретный футбольный эпизод, но и здесь перед нами мироощущение человека середины 80-х годов прошлого века. В обеих поэмах футбол становится тем универсальным способом, который позволяет передать мысли авторов о состоянии мира и о состоянии человека в этом мире, а прежде всего — о своём собственном состоянии, ведь обе поэмы являют собой образцы лирического рода литературы.

description: The characterization and control of quantum effects in the performance of thermodynamic tasks may open new avenues for small thermal machines working in the nanoscale. We study the impact of coherence in the energy basis in the operation of a small thermal machine which can act either as a heat engine or as a refrigerator. We show that input coherence may enhance the machine performance and allow it to operate in otherwise forbidden regimes. Moreover, our results also indicate that, in some cases, coherence may also be detrimental, rendering optimization of particular models a crucial task for benefiting from coherence-induced enhancements.

The Effect of Satellite Galaxies on Gravitational Lensing Flux Ratios

description: Gravitational lenses with anomalous flux ratios are often cited as possible evidence for dark matter satellites predicted by simulations of hierarchical merging in cold dark matter cosmogonies. We show that the fraction of quads with anomalous flux ratios depends primarily on the total mass and spatial extent of the satellites, and the characteristic lengthscale R of their distribution. If R is 100 kpc, then for a moderately elliptical galaxy with a line-of-sight velocity dispersion of 250 km/s, a mass of 3 x 10^9 solar masses in highly-concentrated (Plummer model) satellites is needed for 20% of quadruplets to show anomalous flux ratios, rising to 1.25 x 10^10 solar masses for 50%. Several times these masses are required if the satellites have more extended Hernquist profiles. Compared to a typical elliptical, the flux ratios of quads formed by typical edge-on disc galaxies with maximum discs are significantly less susceptible to changes through substructure -- three times the mass in satellite galaxies is needed to affect 50% of the systems. In many of the lens systems with anomalous flux ratios, there is evidence for visible satellites (e.g., B2045+265 or MG0414+0534). We show that optically identified substructure should not be preponderant among lens systems with anomalies. There are two possible resolutions of this difficulty. First, in some cases, visible substructure may be projected within or close to the Einstein radius and wrongly ascribed as the culprit, whereas dark matter substructure is causing the flux anomaly. Second, bright satellites, in which baryon cooling and condensation has taken place, may have higher central densities than dark satellites, rendering them more efficient at causing flux anomalies.

On the characterization of p-adic Colombeau-Egorov generalized functions by their point values

Subjects: subject: Functional Analysis (math.FA)

description: We show that contrary to recent papers by S. Albeverio, A. Yu. Khrennikov and V. Shelkovich, point values do not determine elements of the so-called p-adic Colombeau-Egorov algebra uniquely. We further show in a more general way that for an Egorov algebra of generalized functions on a locally compact ultrametric space (M,d) taking values in a non-trivial ring, a point value characterization holds if and only if (M,d) is discrete. Finally, following an idea due to M. Kunzinger and M. Oberguggenberger, a generalized point value characterization of such an Egorov algebra is given. Elements of the latter are constructed which differ from the p-adic delta-distribution considered as a generalized function, yet coincide on point values with the latter.

description: Rationales offer a method for app developers to convey their permission needs to users. While guidelines and recommendations exist on how to request permissions, developers have the creative freedom to design and phrase these rationales. In this work, we explore the characteristics of real-world rationales and how their building blocks affect users’ permission decisions and their evaluation of those decisions. Through an analysis of 720 sentences and 428 screenshots of rationales from the top apps of Google Play, we identify the various phrasing and design elements of rationales. Subsequently, in a user study involving 960 participants, we explore how different combinations of phrasings impact users’ permission decision-making process. By aligning our insights with established recommendations, we offer actionable guidelines for developers, aiming to make rationales a usable security instrument for users.

The tiger beetle fauna of Arabia has been fairly intensively studied with separate recent coverage of Yemen (Wranik et al. 1991), Oman (Cassola and Rihane 1996) and eastern Saudi Arabia (Cassola and Schneider 1997) adding to older records from the Red Sea area of Saudi Arabia (Britton 1948). Neither has the UAE been neglected, since separate studies have dealt with its inland (Gillett 1995) and coastal cicindelid fauna (Wiesner 1993, 1996). To date, a total of just 19 species from nine different genera are known from the whole of Arabia, suggesting that because of the size and habitat diversity of the peninsula, further species might occur.
One such has recently turned up on Reem Island, right next door to the burgeoning metropolis of Abu Dhabi, on a site scheduled for massive urban development. Two examples of this very pretty diminutive tiger beetle were collected at a mercury vapour light trap by BH on the 3rd September 2007 (Fig. 4). The beetle was identified by Cassola, and a manuscript to record this species from the UAE is in preparation (Cassola et al., in press). This represents an amazing new record and range extension of a beetle only previously recorded from Iran on the other side of the Arabian Gulf. Unfortunately, it will likely very soon disappear along with its habitat.

description: An oblique-rotating pulsar generates a relativistic striped wind in a pulsar wind nebula (PWN). The termination shock of the PWN compresses the Poynting-flux-dominated flow and drives magnetic reconnection. By carrying out particle-in-cell (PIC) simulations of the termination shock of the PWN, we study the shock structure as well as the energy conversion processes and particle acceleration mechanisms. With the recent advances in the numerical methods, we extend the simulations to the ultra-relativistic regime with bulk Lorentz factor up to γ_{0}=10^{6}. Magnetic reconnection at the termination shock is highly efficient at converting magnetic energy to particle kinetic energy and accelerating particles to high energies. We find that the resulting energy spectra crucially depend on λ/d_{e}. When λ/d_{e} is large (λ\gtrsim40d_{e}) , the downstream particle spectra form a power-law distribution in the magnetically dominated relativistic wind regime with upstream magnetization parameter σ_{0}=10. By analyzing particle trajectories and statistical quantities relevant to particle energization, we find that Fermi-type mechanism dominates the particle acceleration and power-law formation. We find that the results for particle acceleration are scalable as γ_{0} and σ_{0} increase to large values. The maximum energy for electrons and positrons can reach hundreds of TeV if the wind has a bulk Lorentz factor γ_{0}\approx10^{6} and magnetization parameter σ_{0}=10, which can explain the recent observations of high-energy gamma-rays from pulsar wind nebulae (PWNe).

description: The Umm Irna Formation, exposed along the eastern shore of the Dead Sea, has been the focus of intense palaeobotanical study, but more recently, it has been revealed that well-preserved palynological assemblages are also present. The age of the Umm Irna Formation is such that it provides a showcase for taxa from the Guadalupian (mid Permian) to Lopingian (late Permian) which are hard to find in the carbonate-dominated successions to the southeast in the Arabian Peninsula and elsewhere in the Middle East. In this paper distinctive taxa present in the Umm Irna Formation are described and illustrated, and surveyed for their stratigraphic occurrences, to consider their suitability for biozonal indices within the Guadalupian to early Lopingian. Two appear to be promising: Protohaploxypinus uttingii Stephenson and Filatoff, 2000 and Pretricolpipollenites bharadwajii Balme, 1970. The first is distinctive in that it is relatively small, has numerous, very narrow taenaie, and a shrunken intexinal corpus; the second has three narrow distal sulci. Both taxa may have first appearance levels within thePermianabove the base of the OSPZ6 palynological Biozone, and thus may be useful in the future for further biozonation.

description: Objectives: To map travel policies implemented due to COVID-19 during 2020, and conduct a mixed methods systematic review of health effects of such policies, and related contextual factors. Design: Policy mapping and systematic review. Data sources and Eligibility Criteria: for the policy mapping, we searched websites of relevant government bodies and used data from the Oxford COVID-19 Government Response Tracker for a convenient sample of 31 countries across different regions. For the systematic review, we searched Medline (Ovid), PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and COVID-19 specific databases. We included randomized controlled trial, non-randomized studies, modeling studies, and qualitative studies. Two independent reviewers selected studies, abstracted data and assessed risk of bias. Results: Most countries adopted a total border closure at the start of the pandemic. For the remainder of the year, partial border closure banning arrivals from some countries or regions was the most widely adopted measure, followed by mandatory quarantine and screening of travelers. The systematic search identified 69 eligible studies, including 50 modeling studies. Both observational and modeling evidence suggest that border closure may reduce the number of COVID-19 cases, disease spread across countries and between regions, and slow the progression of the outbreak. These effects are likely to be enhanced when implemented early, and when combined with measures reducing transmission rates in the community. Quarantine of travelers may decrease the number of COVID-19 cases but its effectiveness depends on compliance and enforcement and is more effective if followed by testing, especially when less than 14 day-quarantine is considered. Screening at departure and/or arrival is unlikely to detect a large proportion of cases or to delay an outbreak. Effectiveness of screening may be improved with increased sensitivity of screening tests, awareness of travelers, asymptomatic screening, and exit screening at country source. While four studies on contextual evidence found that the majority of the public is supportive of travel restrictions, they uncovered concerns about the unintended harms of those policies.

description: A new species of Saurichthys, S. majiashanensis , is described. It comes from a series of marine vertebrate-bearing beds of the upper member of the Nanlinghu Formation outcropping in the large quarry at the top of Majiashan (Majia Hill) near Chaohu (Hefei City, Anhui Province, China). Its age is Middle Spathian (Olenekian, Early Triassic). This new species deeply differs from the several pre-Spathian species of Saurichthys mainly for having only two longitudinal scale rows together with a reduced grid-like structure for the neural elements in the vertebral column. Further derived characters are in the endoskeleton of the dorsal and anal fin, where radials articulate only to anterior lepidotrichia, the posterior ones being supported by the first scale from the caudal pedicle mid-dorsal and mid-ventral rows, deeply imbedded in the body. In addition, the haemal spines of the caudal region are much enlarged and reversed, with their distal parts pointing forwards. Though the skull is lacking, postcranial characters are enough to justify the erection of a new species. This new Saurichthys species, together with other few actinopterygians, can be considered as the oldest assemblage of the Triassic Middle Fish Fauna, which bloomed probably in the early Anisian and widespread especially all over the Tethys for the Middle Triassic and at least the Carnian in the Late Triassic. This new fish assemblage, together with some of the oldest marine reptiles, is considered as the beginning of the actual Triassic recovery among marine vertebrates.

description: A shallowing-upward carbonate sequence was studied from the outcrop at Gyulakeszi, Tapolca Basin (western Hungary), and it is interpreted as a Middle Triassic (Curionii or younger) platform progradation. Two lithostratigraphic units are distinguished. Microfacies analysis and micropaleontological investigation conducted on the red nodular, cherty limestone (Vászoly and Buchenstein formations) suggest that the lower unit was deposited during the Reitzi and the Secedensis ammonoid zones. The overlying white platform limestone (upper unit) is typical of a prograding platform and includes gravity-driven deposits at the base followed by periplatform facies deposited in shallow marine warm waters around the fair-weather wave base. The section at Gyulakeszi was unaffected by fabric-destructive dolomitization, which is uncharacteristic of similar platform facies in the Balaton Highland. Isopachous and radiaxial fibrous calcite cement found in the grainstone and boundstone facies are indicative of early lithification and diagenesis in the marine phreatic zone. “Evinospongiae”-type cement is described for the first time from the Balaton Highland and it is similar to the outer platform cements published previously from the Alps (Italy and Austria). The progradation could have advanced over the pelagic limestones as early as the Curionii zone, which is an undocumented event in the Veszprém Plateau. Similar event, however, is well known from the Western Dolomites, where aggradation was followed by intense progradation during the Gredleri and Archelaus ammonoid zones. The length of this progradation event at Gyulakeszi, however, is ambiguous since proven Ladinian (Longobardian) rocks are not exposed in the study area and were not penetrated by boreholes in the Tapolca Basin.

description: We analyze the photometric data obtained by PLANET and OGLE on the caustic-crossing binary-lens microlensing event OGLE-2002-BLG-069. Thanks to the excellent photometric and spectroscopic coverage of the event, we are able to constrain the lens model up to the known ambiguity between close and wide binary lenses. The detection of annual parallax in combination with measurements of extended-source effects allows us to determine the mass, distance and velocity of the lens components for the competing models. While the model involving a close binary lens leads to a Bulge-Disc lens scenario with a lens mass of M=(0.51 +- 0.15) M_sol and distance of D_L=(2.9 +- 0.4) kpc, the wide binary lens solution requires a rather implausible binary black-hole lens (M >=126 M_sol). Furthermore we compare current state-of-the-art numerical and empirical models for the surface brightness profile of the source, a G5III Bulge giant. We find that a linear limb-darkening model for the atmosphere of the source star is consistent with the data whereas a PHOENIX atmosphere model assuming LTE and with no free parameter does not match our observations.

Nursing students’ understanding of the concept of culture

Publisher: name: University of British Columbia

description: Using a critical ethnography design, the investigator foregrounds nursing students understanding of the concept of culture, how they learn about the concept of culture, and apply what they learn in providing care for a culturally diverse population. Eight students from diverse ethnic, cultural, and educational backgrounds, with varying lengths of clinical experience voluntarily participated in the study. Data were collected through access to two students' reflective journals and in-depth interviews with students using open-ended questions, which were audiotaped and transcribed verbatim. Socio-demographic data were also collected. The data were analysed using narrative analytical techniques. The findings from this study suggest first, that students hold diverse perspectives on the concept of culture. At the same time, it is also crucial to value and respect the perspectives of others and recognise the implications o f particular ideological stances toward the concept of culture. Second, the process of learning and understanding about culture involves giving voice to multiple representations of realities, and cannot be isolated from socio-cultural, historical, economic, and political contexts. Third, inequalities and oppression that result from particular perspectives on culture can only be overcome when nursing students and nurses engage in a continuous discourse and problematise culture and bring critical perspectives to the processes of learning about culture. In addition, learning about culture must be ongoing and must draw from academic, personal and nursing experiences. Fourth, there is a dialectic relationship between culture and life experiences. The research indicates that the perception of culture influences values and beliefs, and these values and beliefs are rooted in their life experiences, whether they be of a personal, academic, and nursing nature.

description: Exposure of metal surfaces to multiple ultrashort laser pulses under certain conditions leads to the formation of well-defined periodic surface structures. We show how the period of such structures in steel can be tuned over a wide range by controlling the complex interaction mechanisms triggered in the material. Amongst the different irradiation parameters that influence the properties of the induced structures, the angle of incidence of the laser beam occupies a prominent role. We present an experimental and theoretical investigation of this angle dependence in steel upon irradiation with laser pulses of 120 fs duration and 800 nm wavelength, while moving the sample at constant speed. Our findings can be grouped into two blocks. First, we observe the spatial coexistence of two different ripple periods at the steel surface, both featuring inverse scaling upon angle increase, which are related to forward and backward propagation of surface plasmon polaritons. To understand the underlying physical phenomena, we extend a recently developed model that takes into account quantitative properties of the surface roughness to the case of absorbing metals (large imaginary part of the dielectric function), and obtain an excellent match with the experimentally observed angle dependence. As second important finding, we observe a quill writing effect, also termed non-reciprocal writing, in form of a significant change of the ripple period upon reversing the sample movement direction. This remarkable phenomenon has been observed so far only inside dielectric materials and our work underlines its importance also in laser surface processing. We attribute the origin of symmetry breaking to the non-symmetric micro- and nanoscale roughness induced upon static multiple pulse irradiation, leading to non-symmetric modification of the wavevector of the coupled surface plasmon polariton.

description: We present a numerically exact solution for the BCS Hamiltonian at any temperature, including the degrees of freedom associated with classical phase, as well as amplitude, fluctuations via a Monte Carlo (MC) integration. This allows for an investigation over the whole range of couplings: from weak attraction, as in the well-known BCS limit, to the mainly unexplored strong-coupling regime of pronounced phase fluctuations. In the latter, for the first time two characteristic temperatures $T^\star$ and $T_c$, associated with short- and long-range ordering, respectively, can easily be identified in a mean-field-motivated Hamiltonian. $T^\star$ at the same time corresponds to the opening of a gap in the excitation spectrum. Besides introducing a novel procedure to study strongly coupled d-wave superconductors, our results indicate that classical phase fluctuations are not sufficient to explain the pseudo-gap features of high-temperature superconductors (HTS).

description: A new genus and species of fossil Trachypachidae Praedodromeus sangiorgiensis gen. n sp. n. (Coleoptera, Trachypachidae, Eodromeinae), with well developed asymmetrical mandibles, shorter than the head, subrectangular pronotum and slender tibiae, longer than femora, is described from the Kalkschieferzone (uppermost member of the Meride Limestone) of the Swiss side of Monte San Giorgio. Trachypachidae are terrestrial Coleoptera well represented in the Mesozoic fossil record by the extinct family Eodromeinae. Up to now, more than 33 fossil species belonging to 13 genera of Eodromeinae have been described. The new species is part of a collection of fossil insects that includes members of at least six different orders. Based on the ecology of corresponding extant taxa, this insect assemblage provides new insights on the paleoenvironment of Monte San Giorgio area during the Late Ladinian. The assemblage includes terrestrial taxa that support the presence of emerged land and taxa with long-lasting aquatic larval stage (as Plecoptera and Ephemeroptera) that confirm the presence of stable fresh water basins.

description: The Late Triassic in the Southern Alps is marked by an extensive growth of carbonate platforms. Whereas Dolomia Principale dominates the western and central sections, Dachstein Limestone dominates the eastern side of the Southern Alps on the so-called Julian Platform in what is now NW Slovenia. Younger tectonic movements greatly deformed the original configuration of the Julian Platform and its margins are consequently poorly preserved. While late Tuvalian and early Norian platform progradation has been recorded on the northern and eastern side of the platform, no such information is available for the southern edge of the platform, where it borders the deeper Slovenian Basin. Three detailed sedimentological sections from the southern slopes of the Jelovica plateau span from the top of the basinal Bača dolomite to the Slatnik Formation and the prograding slope of the Dachstein Limestone. The progradation has been dated as late Norian in age, and can be correlated to a poorly-expressed coarsening event recorded in previously known sections of the Slovenian Basin. In contrast to deeper parts of the basin, shallow water conditions were established on the Jelovica plateau by the beginning of the Rhaetian.

TAPHONOMIC ASPECTS OF THE RADIAL BACKFILL OF ASTEROSOMIDS IN OLIGO-MIOCENE TURBIDITES OF CENTRAL ITALY (NORTHERN APENNINES)
Creators: name: MONACO, PAOLO
Publisher: name: Università degli Studi di Milano

description: One hundred asterosomid specimens from 24 sections of several flysch facies of the Northern (Tuscan-Romagna-Umbrian) Apennines have been analysed to study their radial backfill using taphonomic characteristics. These characteristics include the stratinomic position in the bed, the shape and morphology of concave or convex tunnels, the type of subhorizontal crossing, the disposition and shape of wrinkles and cracks, and newly recognized fan-shaped, micro-debris flow deposits in the sides of tunnels induced by the radial backfilling compression causing shock in mud. Many types of preservation have been found in Halopoa ichnospecies while other preservational aspects (Asterosoma and Lennea in primis, while the Fucusopsis preservation and aspect has been included in ichnogenus Halopoa). This comparative taphonomic study enhances, for the first time in the turbidites of Apennines, the role of radial backfill as a type of deposit-feeding in deep-sea firmgrounds and softgrounds, produced by soft-bodied organisms (probably worms).

Isomorphic Data Type Transformations

description: In stepwise derivations of programs from specifications, data type refinements are common. Many data type refinements involve isomorphic mappings between the more abstract and more concrete data representations. Examples include refinement of finite sets to duplicate-free ordered lists or to bit vectors, adding record components that are functions of the other fields to avoid expensive recomputation, etc. This paper describes the APT (Automated Program Transformations) tools to carry out isomorphic data type refinements in the ACL2 theorem prover and gives examples of their use. Because of the inherent symmetry of isomorphisms, these tools are also useful to verify existing programs, by turning more concrete data representations into more abstract ones to ease verification. Typically, a data type will have relatively few interface functions that access the internals of the type. Once versions of these interface functions have been derived that work on the isomorphic type, higher-level functions can be derived simply by substituting the old functions for the new ones. We have implemented the APT transformations isodata to generate the former, and propagate-iso for generating the latter functions as well as theorems about the generated functions from the theorems about the original functions. Propagate-iso also handles cases where the type is a component of a more complex one such as a list of the type or a record that has a field of the type: the isomorphism on the component type is automatically lifted to an isomorphism on the more complex type. As with all APT transformations, isodata and propagate-iso generate proofs of the relationship of the transformed functions to the originals.

THE BRECCE DELLA RENGA FORMATION:  AGE AND SEDIMENTOLOGY OF A SYN-TECTONIC CLASTIC UNIT IN THE UPPER MIOCENE OF CENTRAL APENNINES. INSIGHTS FROM FIELD GEOLOGY

description: In the NE Simbruini Mountains, the “Brecce della Renga Fm.” is a clastic unit documenting sedimentation controlled by late Miocene extensional tectonics.The unit has been subdivided into three lithofacies and six sublithofacies, based on the arenite/rudite/pelite ratio. Massive and coarser (up to megablock size) intervals are interpreted as rockfall deposits (likely induced by earthquakes) at the toe of steep submarine escarpments. By contrast, finer levels are interpreted as having been sedimented through avalanching and turbidity flows in more distal settings, and are partly lateral to basinal hemipelagites and siliciclastic turbidites. Pelite lenses, found at various stratigraphic levels, are the result of ponded sedimentation along the clastic margin. Calcareous nannofossils analyses have been performed for age determinations on 60 fossiliferous samples, which were collected in each sublithofacies of the “Brecce della Renga Fm.”. The unit ranges from early Tortonian (MNN8b) to early Messinian (MNN11c). The age and field geometries of the older breccias document the existence of a Tortonian extensional phase, which predated the late Messinian thrusting. A progradation of the clastic wedge can be observed in the Tortonian, while Messinian deposits show a fining upwards trend. The distribution curve of clastics over time can, given the number of synsedimentary faults mapped in the area, be put in relation with the seismicity induced by the activity along such faults, which after reaching an acme in the Tortonian gradually reached a quiescent state in the early Messinian, causing the backstepping of clastic facies.

description: Despite the increasingly active role of civic actors, there is often no possibility for them to participate in project planning and decision-making. This discrepancy leads to costly conflicts and even failures. Unfortunately, the literature on project stakeholder management does not have sufficient theoretical substantiation to address this issue. To fill this knowledge gap, we integrate the concepts of stakeholder salience, public participation, and nonmarket strategy, and apply them to two urban infrastructure projects in Germany. This study contributes to the literature in two dimensions. First, it offers a dynamic and conceptual model for project stakeholder management, providing explanations for different conflict intensities. Second, it advances each individual area of research. Examples include the identification and clustering of so-called nonmarket assets, an examination of the influence of nonmarket strategies on managers’ perceptions of stakeholder salience, and the study of public participation in a corporate–political context, rather than a purely political one.

description: Atractocerus sp. (Coleoptera: Lymexylidae)
 Beetles belonging to the small family Lymexylidae develop in the wood of fallen or damaged trees, feeding on fungus that grows in tunnels bored by the larvae and is an unusual family to find in the UAE. A single specimen attributable to the genus Atractocerus was taken at a mercury vapour light trap by BH on the 19th September 2008 in the Fujairah emirate. It is a soft-bodied beetle with only rudimentary wingcases or elytra (Fig. 5) making it hardly recognisable as a beetle. It too is a new record for the UAE.

description: We show that eleven-dimensional supergravity backgrounds with thirty one supersymmetries, N=31, admit an additional Killing spinor and so they are locally isometric to maximally supersymmetric ones. This rules out the existence of simply connected eleven-dimensional supergravity preons. We also show that N=15 solutions of type I supergravities are locally isometric to Minkowski spacetime.
