description: In case of using methodology of project planning, in the first step we had to create a “good” logic network. We had to determine the successors and predecessors of the tasks. However, usually successors and predecessors proceed from the technology, sometimes (especially in case of IT and innovation projects) these relations between tasks are not explicit. In case of projects, especially IT and innovation projects, one of the most critical points of view is the phase of logic planning. However, it is a very important phase, only slightly supported by any kind of Project Management tools. Our goal was to support the logic planning phase. In our paper a new planning method, namely SNPM (Stochastic Network Planning Method) is introduced through some practical applications. SNPM can determine all feasible solutions with the help of stochastic variables and can also take into consideration all possible precedents. The parameters of logic relations can be changed if the impacts on the project change. With this method the most probable project scenario can be determined taking into account costs and resource demands.

description: The purpose of this paper is to evaluate the impact of the change on the Brazilian exchange rate policy implemented in January 1999, and to analyze agricultural sector transformations. Specifically, the paper is an attempt to identify the economic relations of the aggregate performance of the Brazilian commercial trade balance and total GDP or agricultural GDP, world income, and real exchange rate as of in the 1980-2006 (up to first quarter) period. The main conclusion of the study is that the exchange rate policy bands of Plano Real exerted a negative effect on exports and favored imports. With the liberation of the Brazilian exchange rate, from 1999 on, the estimated relations appear to have a positive net effect on the commercial trade balance of the country. But the statistical results of the econometric model are not reliable.

description: International market for some agricultural commodities can be characterized by oligopoly, in which participants behave in a non cooperative manner, provoking marketing disputes. According to this scenario, strategic trade policies have been utilized to as an instrument of market share contents by international market members. Hence, when a country adopts some strategic trade policy, impacts of such policy are felt by other market participants. A subsidy granted by an exporting country, for instance, may result on a raise in exports; whereas taxing production of exports may work as a deterrent to shipments to the international market.

description: We present a rotational study of Post-T Tauri stars (PTTSs) in Lindroos systems, defined as binaries with early type primaries on the main-sequence (MS) and late-type secondaries on the pre-main-sequence (PMS) phase. The importance of this study in comparison with previous ones is that the Lindroos sample is not X-ray selected so we avoid a possible bias towards fast rotators. In this preliminary study we have monitored eleven stars in the UBVRI bands during two campaigns of ten consecutive nights each. Eight of the observed PTTSs show periodic modulations in their lightcurves and the derived periods range from 1.9d to 8.0d. The comparison of these results with theoretical rotational tracks based on disk-star locking theory shows that star-disk decoupling times of 1-20 Myr could reproduce the rotational properties of the targets, assuming an initial rotation period of ~8d and a mass of 1 Mo. We have studied the rotation-activity relations of Lindroos PTTSs and compared them with those found in other groups of PMS and zero-age main-sequence (ZAMS) ~1 Mo stars. The Lindroos sample displays activity-rotation relations very similar to those found in TTSs. It contains a mixture of very active stars, with Lx/Lbol ratios close to the saturation level of -3, and less active (unsaturated) stars. This could be the result of different star-disk decoupling times. Future monitoring of a larger and unbiased sample of PTTS will be important to confirm the significance of these results.

description: This study identifies the effects of free trade agreements at the multilateral (WTO) and regional (FTAA and MERCOSUR-EU) levels on the bovine meat markets in several regions. In order to evaluate these effects, we used a spatial allocation model, presented as a mixed complementarity problem (MCP). The study identifies the changes in production and consumption levels, as well as the changes in producer and consumer surplus, in four possible scenarios. In general, gains to bovine meat producers in the MERCOSUR countries are expected in all scenarios. Although, these gains are greater when we simulate a multilateral trade liberalization, with or without the elimination of subsidies.

description: We consider a generic nonlinear extension of May's 1972 model by including all higher-order terms in the expansion around the chosen fixed point (placed at the origin) with random Gaussian coefficients. The ensuing analysis reveals that as long as the origin remains stable, it is surrounded by a "resilience gap": there are no other fixed points within a radius r*>0 and the system is therefore expected to be resilient to a typical initial displacement small in comparison to r*. The radius r* is shown to vanish at the same threshold where the origin loses local stability, revealing a mechanism by which systems close to the tipping point become less resilient. We also find that beyond the resilience radius the number of fixed points in a ball surrounding the original point of equilibrium grows exponentially with N, making systems dynamics highly sensitive to far enough displacements from the origin.

description: The study analyzes the behavior of the Brazilian’s beef exports, in natura, during the 1995 to 2003 period. It shows that the substantial increase in exports made the country one of the leading beef exporters and tries to identify the factors that contributed for this growth. The methodological procedures involve the application of the Constant-Market-Share model to identify the sources of growth of the exports through the world trade growth effect, origin of exports effect and competitive effect. The composition effect was not estimated given the fact that the model was applied to only one product. The results show that the competitive and structural effects gave a significant increase to the Brazilian’s exports. The study shows, also, that Brazil increased its market share due the several factors that contributed to an expansion in its exports through new world markets.

description: The effective measurement of transactions costs constitutes a theoretical gap, toward which research agenda has been directed. It is, however, a difficult task, given the involved complexity - amplitude of concepts, definition of the analytical cut, synergic effect among transaction costs, production costs and the institutional environment. From this assumption it emerges the possibility of applying the Measurement Cost Theory, developed by Yoram Barzel, in order to identify governance mechanisms in productive systems. The Measurement Cost Theory, as long as considers as a variable key of analysis the possibility of measuring transacted attributes, confers simplicity and applicability to the study of organizations. In other words, the identification of mechanisms of coordination, instead of being based on assets specificity, as proclaimed by the Transaction Costs Economics, becomes, from the Measurement Costs theory more operational and flexible. Considering the interest for understanding the coordination mechanisms in agri-food systems, the empirical validation of this alternative theoretical approach could be identified as an opportunity of research. It can also be foreseen interdependence between these two frameworks.

These bound states exist irrespective of the sign of the scattering length, contrary to the situation in free space. Using radio-frequency spectroscopy we have measured the binding energy of these dimers as a function of the scattering length and confinement and find good agreement with theory. The strongly interacting one-dimensional Fermi gas which we create in an optical lattice represents a realization of a tunable Luttinger liquid.

description: The article had as objective to evaluate the evolution of the productive structure and identify the key sectors of Parana in the years of 1980, 1985, 1990 and 1995, highlighting the food processing sectors, using estimated input-output matrices. The results showed that the sectors of the transformation industry linked to the food processing sectors lost relative importance in the Parana economy, as much for the linkages with to the other sectors, as for the generation of production value and added value. This loss was more stressed in the more traditional food processing sectors, as Coffee Industry and Vegetal Products, instead of in most modern, as Meat Products, Dairy Products, Sugar Products and Vegetal Oil. Moreover, the production and the income had answered little to the impacts in the final demand in the food processing sectors throughout the analyzed period. Another trend that could be delineated was the change in the productive structure of the State, that became more diversified and complex, in direction of some sectors of the branch services and others emergent ones of the transformation industry, as metallurgy, mechanics and transport equipment.
Learning to show "it hurts!" : the role of developmental factors in predicting young children’s use of self-report scales for pain
Creators: name: Job, Elizabeth Ann
Publisher: name: University of British Columbia
Year: 2009

description: Research that can be used to improve pain assessment in clinical settings and inform management plans for children coping with pain is critical. The current study examines young children use of self-report scales for pain and describes the role of several developmental factors in predicting young children use of this scale. The factors considered were: numerical reasoning, language, overall cognitive development, and age. One hundred and six children, ages 3- to 6-years-old, were tested on their level of development regarding the factors listed above. Their ability to accurately use a standard faces pain scale was measured using a series of hypothetical vignettes depicting pain scenarios common in childhood. Results indicated that 5- and 6-year old children were significantly more accurate in their use of the self-report pain scale than 4-year-old children, who in turn were significantly more accurate in their use of the scale than 3-year old children. However, even the 6-year-olds demonstrated difficulty using the pain scale. Child age was the only factor to significantly predict children's accurate use of the pain scale. The results of this research highlight the pervasive over-estimation of young children abilities to use self-report pain scales and the need for screening tools and training tasks to be developed for use with the scales.

description: Citizen records are scattered between different state organizations. It wastes time, effort, and resources for both citizen and organization to collect, maintain, and update records to fulfill citizen services. Interoperability is a key element that enables seamless collaboration between different entities. It requires non-conventional methods to overcome interoperability challenges such as lack of trust, centralization, and policy and technology differences. Blockchain is a disruptive technology with the potential to overcome these challenges. The technology designed to enable peer-to-peer transactions with elimination of intermediary in a trustless environment through the control of consensus mechanisms. This research aims to explore the status of interoperability in Bahrain, design an interoperable framework, and then test the validity of the framework by implementation of a prototype using blockchain technology. The research will be divided into four phases; I: Information collection, II: Design and modeling the framework, III: Implementation of a prototype, and Phase IV: Measuring the performance of the prototype. This research is in progress and it is expected, once is it complete, to enhance the e-government's plan in the Kingdom of Bahrain to provide better services to citizens and help in the transition from e-government to seamless government, which will lead to sustainable citizen services. On the other hand, the findings of the study is expected to improve the social, economical, and environmental sustainability by the increase in process optimization, reduction of cost and complexity.

description: Motivated by recent electron microscopy studies on the Si3N4/rare-earth oxide interfaces, the atomic and electronic structures of bare beta-Si3N4 surfaces are investigated from first principles. The equilibrium shape of a Si3N4 crystal is found to have a hexagonal cross section and a faceted dome-like base in agreement with experimental observations. The large atomic relaxations on the prismatic planes are driven by the tendency of Si to saturate its dangling bonds, which gives rise to resonant-bond configurations or planar sp^2-type bonding. We predict three bare surfaces with lower energies than the open-ring (10-10) surface observed at the interface, which indicate that non-stoichiometry and the presence of the rare-earth oxide play crucial roles in determining the termination of the Si3N4 matrix grains.

description: Statistical physicists and social scientists both study extensively some characteristic features of the unequal distributions of energy, cluster or avalanche sizes and of income, wealth etc among the particles (or sites) and population respectively. While physicists concentrate on the self-similar (fractal) structure (and the characteristic exponents) of the largest (percolating) cluster or avalanche, social scientists study the inequality indices like Gini and Kolkata etc given by the non-linearity of the Lorenz function representing the cumulative fraction of the wealth possessed by different fraction of the population. We review here, using results from earlier publications and some new numerical as well as analytical results, how the above-mentioned social inequality indices, when extracted from the unequal distributions of energy (in kinetic exchange models), cluster sizes (in percolation models) or avalanche sizes (in self-organized critical or fiber bundle models) can help in a major way in providing precursor signals for an approaching critical point or imminent failure point. Extensive numerical and some analytical results have been discussed.

We present preliminary masses, radii and effective temperatures for the eclipsing binary WW Aurigae, which is composed of two metallic-lined A-type stars. We also reanalyse the data on HD 23642, an A-type eclipsing binary member of the Pleiades open cluster with a metallic-lined component, and determine its distance to be 139 +/- 4 pc. This is in agreement with the traditional Pleiades distance, but in disagreement with distance to the Pleiades, and to HD 23642 itself, derived from Hipparcos trigonometrical parallaxes.

description: The dispersal phase of planet-forming disks via winds driven by irradiation from the central star and/or magnetic fields in the disk itself is likely to play an important role in the formation and evolution of planetary systems. Current theoretical models lack predictive power to adequately constrain observations. We present PRIZMO, a code for evolving thermochemistry in protoplanetary disks capable of being coupled with hydrodynamical and multi-frequency radiative transfer codes. We describe the main features of the code, including gas and surface chemistry, photochemistry, microphysics, and the main cooling and heating processes. The results of a suite of benchmarks, which include photon-dominated regions, slabs illuminated by radiation spectra that include X-ray, and well-established cooling functions evaluated at different temperatures show good agreement both in terms of chemical and thermal structures. The development of this code is an important step to perform quantitative spectroscopy of disk winds, and ultimately the calculation of line profiles, which is urgently needed to shed light on the nature of observed disk winds.

description: Temperature-dependent x-ray diffraction of the low-dimensional spin 1/2 quantum magnet TiOCl shows that the phase transition at T_{c2} = 90 K corresponds to a lowering of the lattice symmetry. Below T_{c1} = 66 K a twofold superstructure develops, that indicates the formation of spin-singlet pairs via direct exchange between neighboring Ti atoms, while the role of superexchange is found to be negligible. TiOCl thus is identified as a spin-Peierls system of pure 1D chains of atoms. The first-order character of the transition at T_{c1} is explained by the competition between the structurally deformed state below T_{c2} and the spin-Peierls state below T_{c1}.

description: Recently studies of the differential nature of the flow angle fluctuations, known as event plane angular decorrelation, indicated that measurements that assume a common symmetry plane may need to consider the flow angle fluctuations effect. Using the HIJING and AMPT models, it is shown that the flow angle fluctuations measurements, obtained with the two- and three-subevents correlation method, could have significant non-flow effects associated with long- and short-range non-flow correlations. The current study demonstrates the four-subevents cumulant methods' ability to reduce the non-flow effects. It is further argued that the measurements using the four-subevents correlation method can be used to provide accurate quantification of the differential flow angle fluctuations.

We combine this perturbative result with NLO accurate predictions in the four-flavour scheme that include the full bottom quark mass dependence by appropriately removing any double-counting stemming from contributions included in both predictions. We thereby obtain state-of-the-art predictions for the inclusive production probability of a Higgs boson via bottom quark fusion at hadron colliders.

description: Although social capital is a potentially important asset for poverty reduction in developing economies, there has been little analysis of factors affecting its formation in developing countries such as Uganda. This paper analyzes what influences households to join local organizations and the intensity of social networks in central Uganda. Social networks were disaggregated by major activity to gain insight into household access, and the interaction between local organizations and social networks was examined. Probit and ordered probit models were estimated to identify what led households to participate in organizations and the intensity of participation. A negative binomial model was applied to analyze the household intensity of social networks. The findings revealed that household characteristics and aspects of village homogeneity influence various dimensions of social capital and that there was positive interaction between the social capital generated by local organizations and that derived from social networks. The study has important policy implications for agricultural extension programs that use a group based approach.

description: Poverty is higher in most African countries than elsewhere in the developing world, and highest in the rural areas. Accelerating growth in agriculture will therefore be critical to sustain growth and reduce poverty, but policy makers are unsure which sub-sector will yield the highest return for a given budget. This paper uses an applied general equilibrium model to simulate productivity gains in sub-Saharan agriculture subject to trade-offs between gains in crops and gains in livestock. The simulated results suggest three conclusions. First, most sub-Saharan economies gain more from research and development (R&D) investment in crops than in livestock, though the SACU (South African Customs Union) economies and Madagascar benefit from sharing it between crops and livestock. Second, when R&D is focused on food crops, sharing investment between crops and livestock also benefits other economies. Third, in economies where sharing R&D investment between crops and livestock is beneficial (e.g. Botswana), general economic growth boosts the benefits from R&D investment in livestock.

description: There is limited knowledge regarding how women interpret their pre-hospital experiences of acute coronary syndrome. In this study, an interpretive descriptive method was used to analyze interviews with eight women who experienced acute coronary syndrome. Analysis of these interviews revealed several factors , including previous experience with cardiac symptoms and interaction s with health care professionals that influenced how these women interpreted their pre-hospital experiences. The participants ' interpretation of these factors of their pre - hospital experience determined whether they followed a clear path or an unclear path to diagnosis and hospital admission. An understanding of how women interpret their experiences with cardiovascular disease will assist health care professionals to provide better services for women who are at risk of, or who are living with, cardiovascular disease.

description: Radiation sensors based on the heating effect of the absorbed radiation are typically relatively simple to operate and flexible in terms of the input frequency. Consequently, they are widely applied, for example, in gas detection, security, THz imaging, astrophysical observations, and medical applications. A new spectrum of important applications is currently emerging from quantum technology and especially from electrical circuits behaving quantum mechanically. This circuit quantum electrodynamics (cQED) has given rise to unprecedented single-photon detectors and a quantum computer supreme to the classical supercomputers in a certain task. Thermal sensors are appealing in enhancing these devices since they are not plagued by quantum noise and are smaller, simpler, and consume about six orders of magnitude less power than the commonly used traveling-wave parametric amplifiers. However, despite great progress in the speed and noise levels of thermal sensors, no bolometer to date has proven fast and sensitive enough to provide advantages in cQED. Here, we experimentally demonstrate a bolometer surpassing this threshold with a noise equivalent power of $30\, \rm{zW}/\sqrt{\rm{Hz}}$ on par with the current record while providing two-orders of magnitude shorter thermal time constant of 500 ns. Importantly, both of these characteristic numbers have been measured directly from the same device, which implies a faithful estimation of the calorimetric energy resolution of a single 30-GHz photon. These improvements stem from the utilization of a graphene monolayer as the active material with extremely low specific heat. The minimum demonstrated time constant of 200 ns falls greatly below the state-of-the-art dephasing times of roughly 100 μs for superconducting qubits and meets the timescales of contemporary readout schemes thus enabling the utilization of thermal detectors in cQED.

description: The concept of a livelihood strategy has become central to development practice in recent years. Nonetheless, precise identification of livelihoods in quantitative data has remained methodologically elusive. This paper uses cluster analysis methods to operationalize the concept of livelihood strategies in household data and then uses the resulting strategy-specific income distributions to test whether the hypothesized outcome differences between livelihoods indeed exist. Using data from Kenya’s central and western highlands, we identify five distinct livelihood strategies that exhibit statistically significant differences in mean per capita incomes and stochastic dominance orderings that establish clear welfare rankings among livelihood strategies. Multinomial regression analysis identifies geographic, demographic and financial determinants of livelihood choice. The results should facilitate targeting of interventions designed to improve household livelihoods.

description: We present Mon-735, a detached double-lined eclipsing binary (EB) member of the $\sim$3 Myr old NGC 2264 star forming region, detected by Spitzer. We simultaneously model the Spitzer light curves, follow-up Keck/HIRES radial velocities, and the system's spectral energy distribution to determine self-consistent masses, radii and effective temperatures for both stars. We find that Mon-735 comprises two pre-main sequence M dwarfs with component masses of $M = 0.2918 \pm 0.0099$ and $0.2661 \pm 0.0095$ $\rm{M}_{\odot}$, radii of $R = 0.762 \pm 0.022$ and $0.748 \pm 0.023$ $\rm{R}_{\odot}$, and effective temperatures of $T_{\rm eff} = 3260 \pm 73$ and $3213 \pm 73$ $\rm{K}$. The two stars travel on circular orbits around their common centre of mass in $P = 1.9751388 \pm 0.0000050$ days. We compare our results for Mon-735, along with another EB in NGC 2264 (CoRoT 223992193), to the predictions of five stellar evolution models. These suggest that the lower mass EB system Mon-735 is older than CoRoT 223992193 in the mass-radius diagram (MRD) and, to a lesser extent, in the Hertzsprung-Russell diagram (HRD). The MRD ages of Mon-735 and CoRoT 223992193 are $\sim$7-9 and 4-6 Myr, respectively, with the two components in each EB system possessing consistent ages.

description: Governments do not have enough resources to make anti-poverty programs available to everyone in many African countries. Targeting the poorest populations could increase the efficiency of available program resources. Anti-poverty programs could target either households or geographical areas. This study compares the potential poverty reduction impact of these two approaches in Uganda. The impact of various policy changes on the poverty rate in Uganda is simulated using the estimated parameters of an econometric model of household consumption. The policies examined are family-planning, increased primary school attendance, increased secondary school attendance, expansion of formal employment and micro-enterprise expansion. The results reveal gains in poverty rate reduction from program targeting as compared to randomly allocating finite program resources to a sub-sample of the population. Furthermore, geographical targeting is shown to be more effective than household targeting for most of the six policies examined in the study.

description: In this article, we show fundamentals and recent advances on the transverse thermoelectric generation, in which a thermopower is generated in the direction perpendicular to an applied temperature gradient. Transverse thermoelectric generation is one of the central topics in condensed matter physics, and can be a breakthrough approach to solve long-standing technological problems with contact resistances in thermoelectric generators. We review here the six currently known driving mechanisms: the ordinary Nernst effect, the anomalous Nernst effect, goniopolar materials, the spin Seebeck effect, Seebeck-driven transverse thermoelectric generation, and ($p \times n$)-type multilayers. This article summarizes the principles and functionalities of these transverse thermoelectric effects and discusses their potential as "Future energy".

description: We examine cross sections for the processes $γN\to NK\bar{K}$ in the framework of a phenomenological Lagrangian. We include contributions from $Λ$ and $Σ$ resonances up to spin 3/2, as well as those from an exotic $Θ^+$. We allow the $Θ^+$ to have spin 1/2 or 3/2, with either positive or negative parity in each case. We also allow the state to be either isovector or isoscalar. We find that the scenario that most closely matches observations at Jefferson Laboratory requires a moderately large coupling of the $Θ^+$ to $NK^*$.
