description: A long-held view in evolutionary biology is that character displacement generates divergent phenotypes in closely related coexisting species to avoid the costs of hybridization or ecological competition, whereas an alternative possibility is that signals of dominance or aggression may instead converge to facilitate coexistence among ecological competitors. Although this counterintuitive process—termed convergent agonistic character displacement—is supported by recent theoretical and empirical studies, the extent to which it drives spatial patterns of trait evolution at continental scales remains unclear. By modelling the variation in song structure of two ecologically similar species of Hypocnemis antbird across western Amazonia, we show that their territorial signals converge such that trait similarity peaks in the sympatric zone, where intense interspecific territoriality between these taxa has previously been demonstrated. We also use remote sensing data to show that signal convergence is not explained by environmental gradients and is thus unlikely to evolve by sensory drive (i.e. acoustic adaptation to the sound transmission properties of habitats). Our results suggest that agonistic character displacement driven by interspecific competition can generate spatial patterns opposite to those predicted by classic character displacement theory, and highlight the potential role of social selection in shaping geographical variation in signal phenotypes of ecological competitors.

description: An advanced intermediate in a projected synthesis of pactamycin has been prepared. Early installation of the C1-dimethylurea functionality allows for its participation in a diastereoselective, chelation-controlled addition of organometal nucleophiles to the C5 prochiral ketone. Four of the molecule's six stereocenters are set with a ketone functional handle provided for subsequent manipulation.

description: Indentation experiments on graphene membranes pre-stressed by hydrostatic pressure show an increase in effective elastic modulus from 300 N/m in non pressurized membranes to 700 N/m for pre-strains above 0.5 %. This pronounced dependence of the stiffness of graphene with strain is attributed to its high anharmonicity and the great influence of out of plane corrugations of this atomic thick membrane in its mechanical properties. Our experimental findings imply that graphene measured stiffness is highly influenced by the presence of corrugations and that the in plane elastic modulus corresponding to atomic bond stretching is more akin to 700 N/m, instead of the commonly accepted 340 N/m.

description: The conservation of emblematic threatened species is in highlight nowadays. Interestingly, few invertebrate
 groups attract scientific attention on this issue while they constitute the vast majority of animal biodiversity. Nevertheless,
 many invertebrate species are nowadays at risk of extinction. This means that plenty of species are currently disappearing
 out of sight. During a survey in the southwestern Atlantic Ocean tubes of an endangered species of cerianthid were sampled.
 This study reports for the very first time the occurrence of the species Phoronis australis in southwestern Atlantic waters
 and the association of phoronids with the genus Ceriantheomorphe. This raises questions on mutual extinction risks for
 symbiotic species and also on the criteria for their inclusion on Red Lists.

description: A method for the asymmetric synthesis of enantioenriched anti-α-hydroxy-β-amino acid derivatives by enantioconvergent reduction of the corresponding racemic α-keto esters is presented. The requisite α-keto esters are prepared via Mannich addition of ethyl diazoacetate to imines followed by oxidation of the diazo group with Oxone. Implementation of a recently developed dynamic kinetic resolution of β-substituted-α-keto esters via Ru(II)-catalyzed asymmetric transfer hydrogenation provides the title motif in routinely high diastereo- and enantioselectivity.

Construction and validation of a scale of sexual self-concept for the elderly Chilean population
Creators: name: Ramirez-Perez, Mauricio
Publisher: name: Open Science Framework

Subjects: subject: Social and Behavioral Sciences

description: Sexual self-concept has a central role in the life of the elderly. Indeed, their sexual self-concept has significant and positive relationships with satisfaction with life, pleasure and willingness to interact with others. However, based on social-cultural prejudice, the elderly are considered asexual individuals, harming their sexual self-concept. This prejudice is relevant in Chile, where the elderly do not have clear information about their sexuality. However, Chilean elderly research is still in its infancy and requires more attention. Hence, this research aims to construct and validate a scale of sexual self-concept for the elderly Chilean population to cover this identified gap in the literature. Sixty items were integrated into the first version of the scale. Ten external judges were asked to assess the content validity. Twenty-eight items were maintained. Subsequently, an instrumental and cross-sectional design was implemented with a non-probabilistic sampling (N = 188). Items were refined with corrected homogeneity indices and conditional estimates of Cronbach's alpha and Omega coefficient. A final scale of 9-items equally distributed in three dimensions was obtained: Sexual self-efficacy (ω = 0.867), Sexual assertiveness (ω = 0.764), and Sexual self-esteem (ω = 0.803). The confirmatory factor analysis reflects that the theoretical model has an adequate fit (CFI = .989; TLI = .984; RMSEA = .086). The data analyses confirmed that the scale has adequate psychometric properties. This scale can be used for multidimensional measurements of sexual self-concept in the elderly in Chile. Further research can confirm its psychometric properties in different settings within the Spanish language population.

description: In this article, we revisit the century-old question of the minimal set of observables needed to identify a quantum state: here, we replace the natural coincidences in their spectra by effective ones, induced by an imperfect measurement. We show that if the detection error is smaller than the mean level spacing, then two observables with Poisson spectra will suffice, no matter how large the system is. The primary target of our findings is the integrable (i.e. exactly solvable) quantum systems whose spectra do obey the Poisson statistics. We also consider the implications of our findings for classical pattern recognition techniques.

description: Anxiety is a significant psychological problem for many children today affecting their social and academic functioning. Research indicates that childhood anxiety can lead to anxiety and depression in adulthood and that early intervention in childhood anxiety is desirable. This professional practicum report discussed the effectiveness and the practical implications for teachers and guidance officers wishing to run the FRIENDS: Prevention of Anxiety and Depression Program in schools. Although the program had applications for both childhood anxiety and depression, the focus of this study was on anxiety. An action research methodology was used to report on the outcomes of FRIENDS as it was run in one Brisbane state school. The program was conducted over three months on a weekly, after -school basis, with a group of children who had been identified by teachers and the guidance officer as displaying anxious behaviours. Home activities involved parental assistance. Workshops were conducted to inform parents of the rationale and theoretical principles behind the program and to support them in the home activities. The program effectiveness was monitored by pre- and post -questionnaires, interviews, observations and active researcher involvement in the program. Implications were discussed and recommendations made to guidance officers and teachers planning to conduct the program in school settings.

description: The present study reports abundance and biomass indices, biological parameters, spatial distribution and population
 dynamics of the horned octopus Eledone cirrhosa (Lamarck, 1798) in the Southern Tyrrhenian Sea. Data come from two series
 of trawl surveys (MEDITS and GRUND) carried out from 1994 to 2004. Overall a total of 1278 specimens of E. cirrhosa were
 caught. By sampling in different bathymetric strata biomass and density indices were calculated for each survey. The highest
 mean density values were observed in the 101-200 m depth range. Comparing the annual MEDITS and GRUND median length,
 no significant differences over time were observed. From the resolution of the MEDITS length frequency distributions (LFDs),
 with Bhattacharya's method, three groups were identified: recruits, young spawners and old spawners. Length frequency
 distributions derived from GRUND surveys showed two groups: recruits (juveniles in the autumn period) and adult individuals.
 Growth parameters obtained in this study were similar to those reported from other areas of the Mediterranean Sea. This result
 could be due to differences in the range of sizes sampled, the methodology applied and the different characteristics of the study
 areas. The yield-per-recruit model appeared to be in a state of slight overfishing.

description: The feeding ecology of the green crab Carcinus maenas was studied across all the estuarine gradient of the
 Mondego River, located within the species natural distribution range, adding information on the Northern branch of this
 estuary. A total of 683 specimens of C. maenas was collected at nine sampling stations during four seasonal surveys, using
 a 2 mm mesh size otter trawl. Stomach contents analyses of 578 specimens showed bivalves, crustaceans, polychaetes and
 algae as the most frequent food items; cannibalism and piscivory were also reported. Isopods and the gastropods
 Littorinidae were new additions to the listed items of C. maenas diet in this estuary. Spatial and temporal variations were
 found for the diet of C. maenas, with differences found between the Southern branch and all other estuarine areas and
 showing higher diet similarities during summer and autumn. Differences in the diet of C. maenas related with ontogeny
 "(size and sex)" were identified, which confirms the species potential to reduce intraspecific competition. The type and
 diversity of prey found in the diet of C. maenas suggest that it is an important predator in the food web of the Mondego
 river estuary, particularly in the adult phase, and confirm its ability to adopt an opportunistic feeding strategy.

description: The stereoselective synthesis of trisubstituted 2-trifluoromethyl pyrrolidines by asymmetric Michael addition/hydrogenative cyclization is described. The direct organocatalytic addition of 1,1,1-trifluoromethylketones to nitroolefins proceeds under mild reaction conditions and low catalyst loadings to provide Michael adducts in high yield with excellent diastereo- and enantioselectivity. Catalytic hydrogenation of the Michael adducts stereoselectively generates 2-trifluoromethylated pyrrolidines bearing three contiguous stereocenters. A stereospecific route to epimeric 2-trifluoromethyl pyrrolidines from a common intermediate is described.

Culture of the marine diatom Phaeodactylum tricornutum with different nitrogen sources: Growth, nutrient conversion and biochemical composition
Creators: name: FIDALGO, J. P.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 1995

description: Cultures of the marine diatom Phaeodaetylum tricornutum were grown in nitrate, nitrite, ammonia or urea media. Nitrogen transformation efficiencies were close to 100% in cultures with nitrate, nitrite or urea, with productivities in dry biomass between 2.2 g.l-1 (urea) and 2.8 g.t1 (nitrate). However growth in ammonia cultures ceased due to a drop in pH of the medium. The biochemical profile was more affected by the growth phase than by the N source. Cellular contents of chlorophylls a and c decreased and the chlorophyll a/c ratio increased when cultures entered the stationary phase. Protein and RNA were higher during exponential growth (about 30% and 8% ash free dry weight (AFDW), respectively), but carbohydrates increased up to 220% in the stationary phase. Although significant differences were observed in cellular contents, the biochemical composition (as % AFDW) of the nitrate, nitrite and urea-grown cells was very similar. The highest total fatty acids and polyunsaturated fatty acids (PUFAs) contents in the stationary phase were obtained in the urea-grown cells, with an eicosapentaenoic acid (EPA) content of 26.8 mg.g-1 of dry biomass.

description: We present the theory of the k-core pruning process (progressive removal of nodes with degree less than k) in uncorrelated random networks. We derive exact equations describing this process and the evolution of the network structure, and solve them numerically and, in the critical regime of the process, analytically. We show that the pruning process exhibits three different behaviors depending on whether the mean degree of the initial network is above, equal to, or below the threshold _c corresponding to the emergence of the giant k-core. We find that above the threshold the network relaxes exponentially to the k-core. The system manifests the phenomenon known as "critical slowing down", as the relaxation time diverges when tends to _c. At the threshold, the dynamics become critical characterized by a power-law relaxation (1/t^2). Below the threshold, a long-lasting transient process (a "plateau" stage) occurs. This transient process ends with a collapse in which the entire network disappears completely. The duration of the process diverges when tends to _c. We show that the critical dynamics of the pruning are determined by branching processes of spreading damage. Clusters of nodes of degree exactly k are the evolving substrate for these branching processes. Our theory completely describes this branching cascade of damage in uncorrelated networks by providing the time dependent distribution function of branching. These theoretical results are supported by our simulations of the $k$-core pruning in Erdos-Renyi graphs.

description: Debates over the relationship between biodiversity and disease dynamics underscore the need for a more mechanistic understanding of how changes in host community composition influence parasite transmission. Focusing on interactions between larval amphibians and trematode parasites, we experimentally contrasted the effects of host richness and species composition to identify the individual and joint contributions of both parameters on the infection levels of three trematode species. By combining experimental approaches with field surveys from 147 ponds, we further evaluated how richness effects differed between randomized and realistic patterns of species loss (i.e. community disassembly). Our results indicated that community-level changes in infection levels were owing to host species composition, rather than richness. However, when composition patterns mirrored empirical observations along a natural assembly gradient, each added host species reduced infection success by 12–55%. No such effects occurred when assemblages were randomized. Mechanistically, these patterns were due to non-random host species assembly/disassembly: while highly competent species predominated in low diversity systems, less susceptible hosts became progressively more common as richness increased. These findings highlight the potential for combining information on host traits and assembly patterns to forecast diversity-mediated changes in multi-host disease systems.

description: In this paper, we give a complete description of the associated primes of every power of the edge ideal in terms of generalized ear decompositions of the graph. This result establishes a surprising relationship between two seemingly unrelated notions of Commutative Algebra and Combinatorics. It covers all previous major results in this topic and has several interesting consequences.

subject: FOS: Educational sciences

description: Adult women who return to study after a period of absence have a particular set of problems, some of which present as barriers to the successful achievement of their academic goals. The aim of the present study was to identify the barriers which mature-aged women faced who were enrolled in a course of study at a metropolitan secondary college. The literature on this topic identified some barriers which were supported by the present study, but in addition, several barriers were unique to the situation at The College. Using educational ethnography as a methodology, the researcher used a questionnaire followed by interviews and a focus group discussion to identify the barriers the women were facing. Results indicated that in addition to expected barriers such as conflict between study and family responsibilities, feelings of poor self-worth, a lack of information and social class, women at The College also found that work commitments, time management, different teaching methods used by some teachers, the level of difficulty of some subjects, assessment policies, and younger students in the same class, also presented as barriers to their success. The results of this study provide new information, concerning barriers to further education for the adult female student. These new barriers have implications for further research.
Asymmetric Total Syntheses of Megacerotonic Acid and Shimobashiric Acid A

description: The asymmetric total syntheses of the α-benzylidene-γ-butyrolactone natural products megacerotonic acid and shimobashiric acid A have been accomplished in nine and 11 steps, respectively, from simple, commercially available starting materials. The key step for each synthesis is the (arene)RuCl(monosulfonamide)-catalyzed dynamic kinetic resolution-asymmetric transfer hydrogenation (DKR-ATH) of racemic α,δ-diketo-β-aryl esters to establish the absolute stereochemistry. Intramolecular diastereoselective Dieckmann cyclization forms the lactone core, and ketone reduction/alcohol elimination installs the α-arylidene.

Publisher: name: Phenomenology and Mind
Year: 2017

description: In the present article, the current situation of the so-called philosophy of mathematical practice is discussed. First, its emergence is evaluated in relation to the “practical” turn in philosophy of science and in philosophy of mathematics. Second, the variety of approaches concerned with the practice of mathematics and the new topics being now object of research are introduced. Third, the possible replies to the question about what counts as mathematical practice are taken into account. Finally, some of the problems that are still open in the philosophy of mathematical practice are presented and some possible new directions of research considered.

description: Tricnidactis errans from Mar del Plata propagates asexually by pedal laceration. Dynamics of asexual propagation was evaluated. Frequency of laceration and number of lacerates per individual showed a correlation with seasonal changes in mean seawater temperature; the highest rate of fragmentation was observed after the maximum water temperature (February-March). Terrans exhibited a clear annual cycle of gametogenesis, but sterile and almost exclusively female specimens were found. Both of them propagate asexually by pedal laceration, producing a similar number of fragments. Asexual reproduction by pedal laceration appears to be the sole mean of propagation in the examined aggregation.
Diel feeding activity of demersal fishes in the Ria de Arousa (Galicia, NW Spain): an area of intense mussel raft culture

description: A study was carried out on the di el feeding pattern of five species of demersal fishes, Lesueurigobius friesii and Gobius niger (Gobiidae), Trisopterus luseus (Gadidae), Callionymus lyra (Callionymidae), and Symphodus cinereus (Labridae), in the Ria de Arousa (Galicia, NW Spain), an estuary that supports an intensive raft mussel culture. We have analyzed stomach contents obtained in different habitats (mussel rafts, beach and central channel) over a diel cycle. Pisidia longieomis is the dominant species of the raft epifauna, and their megalopae made up over 70% of the diet of L. friesii, T. luseus and C. lyra in the middle ria zone, bath in the culture areas and in the central channel. In the inner ria raft station the diet of L. friesii and G. niger was composed mainly of prey from the culture rope epifauna, but no megalopae were present. In the beach zones the diet of G. niger and S. cinereus was dominated by infaunal prey, mainly polychaetes. Due to the abundance of food provided by the associated epifauna, mussel culture influences the feeding habits of demersal fishes in the Ria de Arousa. In general, they fed throughout the day without a main period. However, the spring bloom of P. longicornis larvae changes the diel feeding activity patterns and diet of the demersal fish community. S. cinereus was the only species that showed higher fullness levels during the day in the beach zone, where P. longicornis megalopae were not present.
Reactions of Anilines and Benzamides with a 14-Electron Iridium(I) Bis(phosphinite) Complex:  N−H Oxidative Addition versus Lewis Base Coordination

description: Anilines react with (POCOP)Ir(C6H5)(H), 12, (POCOP = 2,6-(OPtBu2)2C6H3) to yield equilibrium mixtures of 12, the Ir(I) σ-complexes (POCOP)Ir(NH2Ar), 13, and the Ir(III) oxidative addition adducts (POCOP)Ir(H)(NHAr), 14. Quantitative studies of these equilibria for a series of anilines were carried out. Anilines possessing electron-withdrawing groups favor the Ir(III) oxidative addition adduct over the Ir(I) sigma complex. Low temperature studies using p-chloroaniline show that the Ir(I) σ-complex is the kinetic product of reaction and is likely the precursor to the Ir(III) oxidative addition adduct. Reductive elimination of complexes 14 in the presence of ethylene led to the corresponding anilines and the ethylene complex (POCOP)Ir(C2H4). Kinetic analysis of these reactions for 14e,f,g bearing electron-withdrawing aryl groups (Ar- = p-CF3C6H4-, C6F5-, 3,5-bis(CF3)C6H3-) shows the rate is independent of ethylene concentration. The ΔG‡ values for these reductive eliminations fall in the range of 21–22 kcal/mol. X-Ray analysis establishes 14f (Ar- = C6F5-) as a square pyramidal complex with the hydride occupying the apical site. Reaction of 12 with benzamides 21a,b yields quantitatively the Ir(III) oxidative addition adducts, (POCOP)Ir(H)(NHC(O)Ar), 22. X-Ray analysis of 22b (Ar- = C6F5-) shows significant interaction of the carbonyl oxygen with Ir in the site trans to hydride. The barrier to reductive elimination of 22a, 29 kcal/mol, is substantially higher than for complexes 14e,f,g.

description: Two male and one female specimens of the agujon needlefish, Tylosurus acus imperialis, were collected off the south-western Adriatic coast. This finding extends the distribution of the species to the Adriatic Sea. The examination of the ripe female showed that T. acus imperialis is a multiple spawner and that its eggs have sticky filaments, as is typical of the family Belonidae.

description: This paper discusses the first observation of stimulated magnetic resonance transitions between the hyperfine levels of trapped ground state atomic antihydrogen, confirming its presence in the ALPHA apparatus. Our observations show that these transitions are consistent with the values in hydrogen to within 4~parts~in~$10^3$. Simulations of the trapped antiatoms in a microwave field are consistent with our measurements.
Habitat et comportement du mérou Epinephelus marginatus dans la région d'Annaba (Algérie)

Year: 1995

description: An inventory drawn up in Annaba's region (7°47'E-36°58'N) has enabled to take the census of 44 groupers Epinephelus marginatus. These latters showed a bathymetrical repartition positively correlated with their size (r = 0.90 ; P < 0.01). They colonize particularly grottos and rocky breaks. Most of the individuals are outside their shelter and have a slow escape behaviour. Younger individuals are found in shallower waters; they are often indifferent to the diver's presence and sometimes even attracted by him.
New Wine in Old Bottles: The Kind of Political Philosophy We Need
Creators: name: Magni, Beatrice
Publisher: name: Phenomenology and Mind

description: There isn’t an overall consensus on the aim, meaning and role(s) of contemporary political philosophy. The relationship between philosophy and politics has been addressed and sharpened – not just today but in different ways and from various, separate and sometimes conflicting perspectives (Leopold & Stears, 2008). Regardless, the main aims, meaning and role of a field of study are key issues, and the quality and credibility of the research will most likely depend on our capacity to draw a path through this conflicting background. The purpose of this paper is to contribute to drafting elements of a new road map that could lead contemporary political philosophy out of this crippling impasse. It builds on a specific version of political theory – Walzer’s interpretation path reviewed (Walzer, 1985) – and addresses a kind of political practice able to reconcile political philosophy’s normative commitments – as is the case with the Rawls’ four roles of political philosophy (Rawls, 2007) – with its actual ambitions and conditions of achievability (Hall, 2015; Galston, 2010).

description: Debates over the relationship between biodiversity and disease dynamics underscore the need for a more mechanistic understanding of how changes in host community composition influence parasite transmission. Focusing on interactions between larval amphibians and trematode parasites, we experimentally contrasted the effects of host richness and species composition to identify the individual and joint contributions of both parameters on the infection levels of three trematode species. By combining experimental approaches with field surveys from 147 ponds, we further evaluated how richness effects differed between randomized and realistic patterns of species loss (i.e. community disassembly). Our results indicated that community-level changes in infection levels were due to host species composition, rather than richness. However, when composition patterns mirrored empirical observations along a natural assembly gradient, each added host species reduced infection success by 12–55%. No such effects occurred when assemblages were randomized. Mechanistically, these patterns were due to non-random host species assembly/disassembly: while highly competent species predominated in low diversity systems, less susceptible hosts became progressively more common as richness increased. These findings highlight the potential for combining information on host traits and assembly patterns to forecast diversity-mediated changes in multi-host disease systems.
