Determinants of child undernutrition in India. A micro-case study to operationalize the Capability Approach
Creators: name: Tinonin, Cecilia <1981>
Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: SECS-P/02 Politica economica

description: The present research aims at shedding light on the demanding puzzle characterizing the issue of child undernutrition in India. Indeed, the so called ‘Indian development paradox’ identifies the phenomenon according to which higher level of income per capita is recorded alongside a lethargic reduction in the proportion of underweight children aged below three years. Thus, in the time period occurring from 2000 to 2005, real Gross Domestic Production per capita has annually grown at 5.4%, whereas the proportion of children who are underweight has declined from 47% to 46%, a mere one point percent. Such trend opens up the space for discussing the traditionally assumed linkage between income-poverty and undernutrition as well as food intervention as the main focus of policies designed to fight child hunger. Also, it unlocks doors for evaluating the role of an alternative economic approach aiming at explaining undernutrition, such as the Capability Approach. The Capability Approach argues for widening the informational basis to account not only for resources, but also for variables related to liberties, opportunities and autonomy in pursuing what individuals value.The econometric analysis highlights the relevance of including behavioral factors when explaining child undernutrition. In particular, the ability of the mother to move freely in the community without the need of asking permission to her husband or mother-in-law is statistically significant when included in the model, which accounts also for confounding traditional variables, such as economic wealth and food security. Also, focusing on agency, results indicates the necessity of measuring autonomy in different domains and the need of improving the measurement scale for agency data, especially with regards the domain of household duties. Finally, future research is required to investigate policy venues for increasing agency in women and in the communities they live in as viable strategy for reducing the plague of child undernutrition in India.

description: We present a series of examples of precompact, noncompact, reflexive topological Abelian groups. Some of them are pseudocompact or even countably compact, but we show that there exist precompact non-pseudocompact reflexive groups as well. It is also proved that every pseudocompact Abelian group is a quotient of a reflexive pseudocompact group with respect to a closed reflexive pseudocompact subgroup.
Studi sull'epigramma scoptico greco
Creators: name: Ceccaroli, Stefano <1982>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: L-FIL-LET/02 Lingua e letteratura greca

description: The dissertation is divided into two parts: the first synthesis focused on the definition of the
epigram scoptico imperial age, the second analysis concerns the study of the minor poets of Book XI.
In the Introduction (I), the attention focuses on the genesis of imperial scoptic epigram: here
you try to draw a picture of the satirical Greek literature before the middle of the century AD to identify the debts of the scoptic epigram, especially Lucillius’, in respect of previous authors (from the Middle-up comedy to epigrams of the Crown of Philip), and to emphasize the remoteness of this
literary phenomenon from other experiences of ironic and satirical poetry (Catullus).
In the chapter on the Themes (II), the study was limited to professional groups and those
most targeted (doctors, grammarians, etc..), to that particular type represented by the satire on
ethnic groups. The study of minor poets is necessarily preceded by a general discussion on the
authors most representative of the greek satiric poetry: Lucillius, Ammianus, Nicarchus and
Palladas (III).
All the minor poets of the eleventh book, which you can not provide a date, have been
regarded by scholars as the ‘poets of Diogenian’: the chapter on Anthologion of Diogenian (IV),
which is undergoing critical to the existence (assumed but never proven) of the lost source of Book XI, therefore, serves as an introduction to the commentary of the authors required minors. During the discussion they are not qualified as poets ‘poets of Diogenian’, but are divided into two categories: those included in the string of alphabetically ordered AP XI 388-436 (V), and those who
are not part of (VI).
Finally, a separate chapter (VII) is devoted to the age-old question of epigrams assigned to Lucian, both in the string of alphabetically ordered epigrams, as well as outside it.

description: Quantum algorithms often benefit from the ability to execute multi-qubit (>2) gates. To date such multi-qubit gates are typically decomposed into single- and two-qubit gates, particularly in superconducting qubit architectures. The ability to perform multi-qubit operations in a single step could vastly improve the fidelity and execution time of many algorithms. Here, we propose a single shot method for executing an i-Toffoli gate, a three-qubit gate gate with two control and one target qubit, using currently existing superconducting hardware. We show numerical evidence for a process fidelity over 98% and a gate time of 500 ns for superconducting qubits interacting via tunable couplers. Our method can straight forwardly be extended to implement gates with more than two control qubits at similar fidelities.

description: We present the light-cone QCD sum rules up to twist 6 for the electromagnetic form factors of the $Λ$ baryon. To estimate the magnetic moment of the baryon, the magnetic form factor is fitted by the dipole formula. The numerical value of our estimation is $μ_Λ=-(0.64\pm0.04)μ_N$, which is in accordance with the experimental data and the existing theoretical results. We find that it is twist 4 but not the leading twist distribution amplitudes that dominate the results.

description: rom Cosmos to Man and back again. A reading of Atlas Mnemosyne, Panel B The A, B, and C Panels that open Aby Warburg’s Mnemosyne Atlas define the “orientation” and coordinates (geographical, historical, cultural) of the Atlas as a whole and set the grid for the analysis of the manifestations of the Classical tradition. While the first panel, Panel A, presents the three different “maps” of reality (cosmological, geographical, genealogical), Panel B focuses on one of the implicit themes of Panel A: the relationship between macro and microcosm and the consequences of the system that this relationship comes to design. The images of this panel seem to all present the human body as a central figure. The need to represent and relate the human body to the cosmos is, in fact, expressed in this series of images that relate to the influences of the cosmos on man, establishing a correspondence between their respective systems. In the figures picked up on the panel, we see how from the Hellenistic to the Medieval and until to the Modern era, the human body is subordinated to the influences from planets and stars, first in a daemonic and then in a magical way. Only in two Renaissance examples, the scheme of this harmonious relationship is portrayed in a geometrical and logical form (Leonardo da Vinci). Human body is no longer subjected to the astral powers but is freed from cosmic influences. It is Leonardo's Man that will give his proportional measures to cosmos, not vice versa. Anthropocentrism instead of andropathia.

description: We study the symmetry and the spatial uniformity of orientational order of the biaxial nematic phase in the light of recent experimental observations of phase biaxiality in thermotropic bent-core and calamitic-tetramer nematics. We present evidence supporting monoclinic symmetry, instead of the usually assumed orthorhombic. We describe the use of deuterium NMR to differentiate between the possible symmetries. We present the spatial aspects of biaxial order in the context of the cluster model, wherein macroscopic biaxiality can result from the field-induced alignment of biaxial and possibly polar domains. We discuss the implications of different symmetries, in conjunction with the microdomain structure of the biaxial phase, on the alignment of biaxial nematics and on the measurements of biaxial order.

title: Studies Toward the Synthesis of a- and B- Mercapto Alanine Derivatives, and of a,B- and B, B- Dimercapto Alanine Derivatives
Creators: name: Kolar, Aldean James
Publisher: name: Utah State University
Year: 1978

description: A convenient, economical, large scale synthesis of N-acetyldehydro-alanine (a-acetamidoacrylic acid) and its methyl ester was developed via a sequence of N-chlorination-dehydrochlorination. The method was extended to the synthesis of the corresponding N-benzoyl, N-phenylacetyl and N-benzyloxycarbonyl derivatives.
The conversion of a-methoxy-N-acetyl alanine derivatives to the corresponding a-mercapto alanine derivatives, using zinc chloride and an appropriate mercaptan, was investigated. Methyl a-methoxy-N-acetyl-D, L-alaninate was successfully converted to the a-acetylthio derivative, in 24% yield; however, a 90% yield could be obtained by treatment of the dehydroalanine derivative with hydrogen chloride gas in neat thiolacetic acid.
A facile conversion of the a-acetylthio derivative to the a-methoxy derivative, using sodium methoxide in methanol, was observed to occur.
The normally facile conversion of an acetylthio group to a mercapto group, using sodium borohydride, gave mixtures of the a-mercapto derivative and alanine derivative.
The reactions at the a position of a-hetero-N-acetyl-D,L-alanines and a,B-disubstituted N-acetyl-D,L-alanine derivatives seemed consistent with the formation of an acylimine intermediate under basic conditions and a carbonium ion intermediate under acidic conditions.
From these studies, a facile, clean synthesis of a-halo-a-mercapto-and a-alkoxy-N-acetyl-D,L-alanine derivatives was accomplished.
All attempts to synthesize a,B-dimercapto derivatives failed because the B-halogen could not be replaced with a mercapto group when the a position was a mercapto or methoxy derivative. Attempts to generate a B-mercapto-a-halo derivative also failed.
A facile synthesis of the E and Z isomers of methyl B-chloro-N-acetyldehydroalaninate was developed. The ratio of Z to E isomers was found to vary with the base used for the elimination.
The E and Z isomers of methyl B-chloro-N-acetyldehydroalaninate were converted to the B-mercapto derivatives by reaction with mercaptan. The reaction proceeded with retention of stereochemistry.
The formation of B-substituted N-acetyldehydroalanine derivatives seemed consistent with an acylimine intermediate followed by a sequence of Michael-type addition and dehydrochlorination.
A study of the conversion of the B-mercapto-N-acetyldehydroalanine derivatives to mixed dithioacetals, which would be useful in the synthesis of natural antibiotics, was undertaken. This approach to the synthesis of mixed dithioacetals was unsuccessful because an exchange of mercapto groups was observed, the addition of a second, different mercaptan failed or the yield was too low to be synthetically useful.
A synthesis of B,B-dimercapto-N-aeetyldehydroalanine (mixed, unsaturated dithioacetals) derivatives was accomplished. However, because of low yields, a reduction to B,B- dimercapto-N- acetyl-D,L-alanine derivatives (mixed dithloacetals) was not investigated.

description: The first version of the Binary Population Synthesizer (BiPoS1) is made publicly available. It allows to efficiently calculate binary distribution functions after the dynamical processing of a realistic population of binary stars during the first few Myr in the hosting embedded star cluster. Instead of time-consuming N-body simulations, BiPoS1 uses a stellar dynamical operator which determines the fraction of surviving binaries depending on the binding energy of the binaries. The stellar dynamical operator depends on the initial star cluster density as well as the time until the residual gas of the star cluster is expelled. BiPoS1 has also a galactic-field mode, in order to synthesize the stellar population of a whole galaxy. At the time of gas expulsion, the dynamical processing of the binary population is assumed to efficiently end due to the subsequent expansion of the star cluster. While BiPoS1 $has been used previously unpublished, here we demonstrate its use in the modelling of the binary populations in the Orion Nebula Cluster, in OB associations and as an input for simulations of globular clusters.

description: We investigate quantum tunneling in a translation invariant chain of particles. The particles interact harmonically with their nearest neighbors, except for one bond, which is anharmonic. It is described by a symmetric double well potential. In the first step, we show how the anharmonic coordinate can be separated from the normal modes. This yields a Lagrangian which has been used to study quantum dissipation. Elimination of the normal modes leads to a nonlocal action of Caldeira-Leggett type. If the anharmonic bond defect is in the bulk, one arrives at Ohmic damping, i.e. there is a transition of a delocalized bond state to a localized one if the elastic constant exceeds a critical value $C_{crit}$. The latter depends on the masses of the bond defect. Superohmic damping occurs if the bond defect is in the site $M$ at a finite distance from one of the chain ends. If the observation time $T$ is smaller than a characteristic time $τ_M \sim M$, depending on the location M of the defect, the behavior is similar to the bulk situation. However, for $T \gg τ_M$ tunneling is never suppressed.

title: Model Studies for Molybdenum Enzymes. The Reduction of Cytochrome C by Molybdenum(V)-Cysteine Complexes
Creators: name: Lawrence, Glen D.

Year: 1976

description: The reduction of ferricytochrome c ( cyt c^III), as well as some iron ligand complexes and chemically modified derivatives of cyt c^III, by two molybdenum(V)-cysteine complexes has been investigated as a model for electron transfer in molybdenum enzymes. The reduction of cyt c^III by di-μ-oxo-bis[oxo(L-cysteinato)molybdate(V)] (I) is first order in cyt c^III and zero order in I over a wide range in concentration of I at neutral pH. The reduction of cyt c^III by μ-oxo-bisfoxodihydroxo(L-cysteinato) molybdate(V)] (II) is first order in both reactants and has a rate several orders of magnitude greater than the rate of reduction by I. Activation parameters have been determined for both reactions.
The reduction of two pyridoxal phosphate derivatives of cyt c^III by I proceeds at the same rate as the reduction of native cyt c^III, while the mononitromonotyrosyl derivative is reduced somewhat faster. The reduction of the N-formyltryptophyl derivative of cyt c^III by I is biphasic, with the fast phase proceeding with a rate similar to the native cyt c^III and the slow phase being somewhat slower. The reduction by I of all derivatives studied is first order in cyt c^III and zero order in I, suggesting the mechanism does not change with these chemically modified forms of cyt c^III.
The pyridoxal phosphate and mononitromonotyrosyl derivatives of cyt c^III are reduced by II with rates similar to the native cyt c^III and by the same mechanism. The reduction of the N-formyltryptophyl derivative by II has complicated kinetics which suggest the presence of at least two formyl-cyt c^III species.
The reduction of the cyanide, azide and imidazole complexes of cyt c^III by II occurs at a greatly reduced rate and by a different mechanism than the reduction of native cyt c^III The rate of reduction of the cyanide and azide complexes is dependent on the rate of dissociation of the ligand cyt c^III complex and independent of the concentration of II. The reduction of the imidazole complex by II is much more complicated, with the rate independent of II at very low concentrations but shows a dependence on the concentration of II at higher concentrations.
Rate constants have been determined for the reactions and possible mechanisms have been developed. The results have been discussed with regard to electron transfer in molybdenum enzymes and electron transfer to cyt c^III This study is especially valuable as a model for the hepatic sulfite oxidase enzyme.

description: Abstract

Studying agricultural land tenure in Algeria inevitably brings to mind a whole historical process in which land was the main issue, both during colonisation and in the post-independence period, when it was at the heart of political and even ideological choices. In Algeria, the land issue is becoming crucial. For a wide variety of reasons and to varying degrees, land tenure is at the heart of the debate and is a key issue in the search for a solution to the complex issue of agricultural land tenure, and this has been the case throughout all the reforms: from self-management to the concession of land in the State's private domain, not forgetting privately-owned land, state-owned property and wakfs or habous. It is therefore important to put in place legal instruments aimed at securing land and improving agricultural consistency and structures. The municipality of Kerkera, an agricultural region located in the west of the Wilaya of Skikda (eastern Algeria), is facing a twofold crisis: on the one hand, a housing crisis, with insufficient housing stock and a demand that continues to increase with population growth, and on the other, a land crisis, insofar as the available land is used for agricultural purposes and is privately owned.
title: The Photochemical Reduction of Octacyanomolybdate(V) Ion in Aqueous Solutions
Creators: name: Gray, Gordon W.
Publisher: name: Utah State University
Year: 1970

description: The photochemical reactions occurring in aqueous solutions of octacyanomolybdate(V) ion, Mo(CN)_8^3-, during irradiation with light of 365 and 436 nm wavelengths were studied. The quantum yields and reaction products were determined for neutral, unbuffered solutions as well as solutions buffered at pH 4.0, 7.0, and 9.0.
The results of these studies showed that the Mo(CN)_8^3- ion is rapidly reduced by light to a Mo(IV) complex. In neutral or acidic media, the initial photoreduction product was found to be the red heptacyanoaquomolybdate(IV) ion, Mo(CN)_7(H_2O)^3-. Photolysis in basic solution gave the yellow heptacyanohydroxomolybdate(IV) ion, Mo(CN)_7(OH)^4-, as an unstable intermediate. Hydrolysis of this complex to the blue tetracyanohydroxooxomolybdate(IV) ion, Mo0(OH)(CN)_4^3-, occurred rapidly in base. In each case, cyanogen, (CN)_2, and cyanate ion, OCN^-, were formed. Additionally, in neutral solutions, the formation of hydrogen ion during the irradiation of the sample gave a rapid drop in the pH of the solution.
Measurements of the product quantum yields for Mo(IV) complexes, *_Mo(IV), gave values that were always greater than one and which increased rapidly with increasing pH of the irradiated solutions, The values were the same for both irradiating wavelengths, showing no wavelength effect for the reaction, The quantum yields determined for *_Mo(IV) were 1.51, 1.59, 3.10, and 4.29 for pH 4 , neutral pH, pH 7, and pH 9 solutions respectively.
From the experimental results, a reaction mechanism is suggested for each of the aqueous media used, The initial photolytic reactions are the same in all solutions with subsequent thermal reactions being responsible for the variation of *_Mo(IV) with the pH of the solution.
Experimental studies of competition among four species of voles
Creators: name: Hawes, David Bruce
Publisher: name: University of British Columbia
Year: 2010

description: The competitive interactions among four species of voles, Clethrionomys gapperi, Microtus oregoni, M. longicaudus, and M. townsendii (Cricetidae: Rodentia), were studied in the vicinity of Vancouver, B.C., Canada. Species occurrences in five vegetationally distinct habitats were ascertained by trapline sampling. Microtus oregoni occurred ubiquitously, whereas the other three species were restricted to one or two habitats and did not overlap with each other. Although species occurrences were predictable on the basis of subjectively defined habitats, they were not predictable on the basis of various environmental parameters. Overlapping or contiguous populations of voles were studied by means of mark and recapture methods and experimentation. M. longicaudus could not be induced to utilize atypical, but apparently suitable, habitat by experimental removal of M. oregoni from that habitat. The overlap between C. gapperi and M. oregoni was found to have a seasonal component, being greatest during the non-breeding season. Microtus oregoni and M. townsendii were found to significantly affect each other, and this effect was shown to be a function of substrate topography. Experimental introduction of M. townsendii into an area previously occupied only by M. oregoni caused reductions both in the population size of M. oregoni and in its range of utilized habitat. Subsequent to the introduction of M. townsendii, the M. oregoni population was excluded from flat habitat and restricted to elevated areas. A survey of 14 different sites disclosed that M. oregoni and H. townsendii populations were negatively correlated and that also the height of the plot above the winter water table affected species composition. Predation by hawks and owls did not explain coexistence of these two vole species. Apparent character displacement of M. oregoni populations was observed: individual body weights in M. oregoni populations sympatric with M. townsendii were significantly smaller than those in other populations of M. oregoni. These results indicate that M. townsendii competes with M. oregoni by interference competition, while M. oregoni appears to escape this interference by burrowing. A similar relationship is hypothesized between M. oregoni and M. Iongicaudus. Additionally, specializations of each vole species and limitations imposed by these specializations are discussed. The relevance of these specific findings is discussed in relation to the distribution of microtine rodents in North America.

description: A "compensated" isocurvature perturbation consists of an overdensity (or underdensity) in the cold dark matter which is completely cancelled out by a corresponding underdensity (or overdensity) in the baryons. Such a configuration may be generated by a curvaton model of inflation if the cold dark matter is created before curvaton decay and the baryon number is created by the curvaton decay (or vice-versa). Compensated isocurvature perturbations, at the level producible by the curvaton model, have no observable effect on cosmic microwave background anisotropies or on galaxy surveys. They can be detected through their effect on the distribution of neutral hydrogen between redshifts 30 to 300 using 21 cm absorption observations. However, to obtain a good signal to noise ratio, very large observing arrays are needed. We estimate that a fast Fourier transform telescope would need a total collecting area of about 20 square kilometers to detect a curvaton generated compensated isocurvature perturbation at more than 5 sigma significance.

description: Abstract

Female genital mutilation has received attention because of its health complications and the recognition that it represents human rights abuse and violence against females. The study assessed the knowledge and prevalence of female genital mutilation among secondary school students in Shagamu, Nigeria and its implication for feminist social work practice. The study used a descriptive survey and stratified sampling technique was used to select 322 students from federal government girl’s college Shagamu. A questionnaire titled the knowledge and prevalence of female genital mutilation among secondary school students was used to collect data for the study. The findings showed that the female students had a fair knowledge of female genital mutilation. Also it was found that there is a high prevalence of FGM because it is an act that is still widely practiced. It is often done because of the social pressure to conform to what others do. The study recommends that health education intervention strategy be employed by feminist social workers nationwide through the mass media. There should be more efforts to raise awareness about the dangers and human rights abuses of FGM among parents and students.

description: (Abridged) The dynamical ejection of stars from star clusters affects the shape of the stellar mass function (MF) in these clusters, because the escape probability of a star depends on its mass. The objective of this paper is to provide and to apply a simple physical model for the evolution of the MF in star clusters for a large range of the parameter space. The model is derived from the basic principles of two-body encounters and energy considerations. It is independent of the adopted mass loss rate or initial mass function (IMF), and contains stellar evolution, stellar remnant retention, dynamical dissolution in a tidal field, and mass segregation. It is found that the MF evolution in star clusters depends on the disruption time, remnant retention fraction, initial-final stellar mass relation, and IMF. Low-mass stars are preferentially ejected after t~400 Myr. Before that time, masses around 15-20% of the maximum stellar mass are lost. The degree of low-mass star depletion grows for increasing disruption times, but can be quenched when the retained fraction of massive remnants is large. The highly depleted MFs of certain Galactic globular clusters are explained by the enhanced low-mass star depletion that occurs for low remnant retention fractions. Unless the retention fraction is exceptionally large, dynamical evolution always decreases the mass-to-light ratio. The modeled evolution of the MF is consistent with N-body simulations when adopting identical boundary conditions. However, it is found that the results from N-body simulations only hold for their specific boundary conditions and should not be generalised to all clusters. It is concluded that the model provides an efficient method do understand the evolution of the stellar MF in star clusters under widely varying conditions.

description: Taxpayer dollars can be used more efficiently by land management agencies to monitor streams if agency-wide monitoring protocols are adopted. To address this issue, the Bureau of Land Management (BLM) developed the National Aquatic Monitoring Framework (NAMF) to implement standardized assessments of stream condition and trend in the Western United States. As one of the first applications of the NAMFI sought to develop and apply an analytical framework to determine the biological condition of streams, extent of in stream stressors and their impact on biological condition, and anthropogenic sources of stressors in Northeast California and Northwest Nevada over three years at a cost of $80,000. I measured biological, chemical, and physical attributes to determine the condition of stream sat 70 spatially distributed random locations. I found 45% of BLM stream km in the study area have degraded biology, 68% have excessive total nitrogen (TN), 43% have canopy cover below expected conditions, and 37% have excessive total phosphorus (TP). Excessive TN and TP and degraded riparian complexity (RC) were most strongly related to degraded biological conditions. The occurrence of excess TN and TP was most associated with livestock grazing. RC was identified as a stressor, but was not associated with land uses. This study provides an example of the data and analytical approach needed to help the BLM adaptively manage streams and rivers in compliance with federal regulations while efficiently using taxpayer dollars.

description: Abstract

The approach used by this study is a descriptive qualitative method to measure the performance of SPBE if implemented into the budgeting system and provide solutions when SPBE does not show good performance. This study was conducted by field screening at the Regional Government Budget Team (TAPD) in 29 regencies and 6 cities under the province of Central Java. The results obtained SPBE performance only reached 42% where in order to reach 100% the implementation of SPBE must be increased by 58%. To do that the implementation must contain elements of Value for Money (VFM) which has the principles of efficiency, effectiveness and economy. The results of this study provide a solution, namely improving coordination and collaboration between business processes and electronic systems in the form of data and information exchange, as well as SPBE services. Improving integrity and providing more supportive access. Local governments must strive to increase the availability of competent human resources. With this improvement, SPBE is expected to be able to contribute significantly to the management of budgeted costs so that the process to the outcome is in line with the budgeted cost (not less and not more).

description: Ternary flavor mixtures of ultracold fermionic atoms in an optical lattice are studied in the case of equal, repulsive on-site interactions U>0. The corresponding SU(3) invariant Hubbard model is solved numerically exactly within dynamical mean-field theory using multigrid Hirsch-Fye quantum Monte Carlo simulations. We establish Mott transitions close to integer filling at low temperatures and show that the associated signatures in the compressibility and pair occupancy persist to high temperatures, i.e., should be accessible to experiments. In addition, we present spectral functions and discuss the properties of a ``semi-compressible'' state observed for large U near half filling.

description: Developing a computer program is not an easy task. Studies reported that a large number of computer science students decided to change their major due to the extreme challenge in learning programming. Fortunately, studies also reported that learning various self-regulation strategies may help students to continue studying computer science. This study is interested in assessing students’ self-regulation, in specific their task understanding and its revision during programming endeavors. Task understanding is specifically selected because it affects the entire programming endeavor.
In this qualitative case study, two female and two male senior computer science students were voluntarily recruited as research participants. They were asked to think aloud while answering five programming problems. Before solving the problem, they had to explain their understanding of the task and after that answer some questions related to their problem-solving process. The participants’ problem-solving process were video and audio-recorded, transcribed, and analyzed.
This study found that the participants’ were capable of tailoring their problem-solving approach to the task types, including when understanding the tasks. Given enough time, the participants can understand the problem correctly. When the task is complicated, the participants will gradually update their understanding during the problem-solving endeavor. Some situations may have prevented the participants from understanding the task correctly, including overconfidence, being overwhelmed, utilizing an inappropriate presentation technique, or drawing knowledge from irrelevant experience. Last, the participants tended to be inexperienced in managing unfavorable outcomes.

title: Patterns of Threatened Vertebrates Based on Trophic Level, Diet, and Biogeography

description: Humans have indirectly and directly contributed to the extinction of over 500 species within the past 500 years, a rate far higher than we have seen in the past. The high extinction rate and the fact that 18% of vertebrates may become extinct within the next century have pushed Earth into a biodiversity crisis. Understanding what makes species more at risk of extinction is needed to protect Earth’s biodiversity.
Generally, it is expected that predators have greater extinction risk than omnivores and herbivores because predators are larger in body size, depend on other animal species for food, need large home ranges, and have fewer individuals within their populations. However, no study to date has actually tested the assumption that predators have the highest extinction risk. This question is important to understand because diet is associated with the ecological role a species plays in an ecosystem.
We compared the extinction risk of species with different diets to determine species in which trophic level are proportionately more at risk of extinction. We classified each species’ diet, trophic level (i.e.,predator, omnivore, and herbivore), body size, habitat, geographic region, system, and associated threats. We focused our analyses on all mammals, birds, and reptiles assessed by the International Union for the Conservation of Nature. We then compared the expected and observed proportions of threatened species within each trophic level and diet group at global, system, habitat, and regional scales.
We found that predators, except scavengers, fish-eating birds, and obligate mammal and bird eaters, were not more threatened than expected. On the other hand, herbivores consistently had greater proportions of threatened species than expected. Specifically within herbivores, fruit, grass, and leaf-eating species had high proportions of threatened species. When we separated large-bodied and small-bodied species, we found that most large-bodied species, regardless of their trophic level, had greater proportions of threatened species. When we looked at the regions and habitats where species were more often threatened, we found that herbivores were highly threatened in south and Southeast Asia, sub-Saharan Africa, and Oceania. In addition, herbivores were highly threatened in tropical forests, marine coasts, and sometimes grasslands. Overall, terrestrial herbivores and marine predatory birds were highly threatened. We found that these patterns may have resulted from overexploitation, habitat alteration, and pollution targeting herbivores and sometimes omnivores.
These findings suggest that we should shift conservation focus from predators to include herbivores. The most threatened species, tropical herbivores, scavengers, and mammal, bird, and fish eaters should be of highest conservation priority.

description: Supergravity provides the effective field theories for string compactifications. The deformation of the maximal supergravities by non-abelian gauge interactions is only possible for a restricted class of charges. Generically these `gaugings' involve a hierarchy of p-form fields which belong to specific representations of the duality group. The group-theoretical structure of this p-form hierarchy exhibits many interesting features. In the case of maximal supergravity the class of allowed deformations has intriguing connections with M/string theory.

description: We investigate differences in Spitzer/IRAC 3.6 and 4.5micron photometry that depend on observing strategy. Using archival calibration data we perform an in-depth examination of the measured flux densities ("fluxes") of ten calibration stars, observed with all the possible observing strategies. We then quantify differences in the measured fluxes as a function of 1) array mode (full or subarray), 2) exposure time, and 3) dithering versus staring observations. We find that the median fluxes measured for sources observed using the full array are 1.6% and 1% lower than those observed with the subarray at [3.6] and [4.5], respectively. Additionally, we found a dependence on the exposure time such that for [3.6] observations the long frame times are measured to be lower than the short frame times by a median value of 3.4% in full array and 2.9% in subarray. For [4.5] observations the longer frame times are 0.6% and 1.5% in full and subarray respectively. These very small variations will likely only affect science users who require high-precision photometry from multiple different observing modes. We find no statistically significant difference for fluxes obtained with dithered and staring-modes. When considering all stars in the sample, the fractional well depth of the pixel is correlated with the different observed fluxes. We speculate the cause to be a small non-linearity in the pixels at the lowest well depths where deviations from linearity were previously assumed to be negligible.
