Features of good practice for safeguarding and valorising intangible cultural heritage: the Tocatì International Festival of Street Games

Purpose of the paper : The aim of this paper is to analyse the extent to which the uniquely successful TocatA¬ International Festival of Street Games, which has been promoted by the Associazione Giochi Antichi (Traditional Games Association) since 2003, can be considered an example of good practice for safeguarding an intangible cultural heritage, and the factors underlying its success. Methodology : The qualitative approach of this paper is based on a case study. The data were collected by conducting in-depth interviews of the organizers of the Tocati International Festival. Results : The results confirmed the working hypothesis and highlighted the determinants of the success of the Festival in safeguarding the intangible cultural heritage of traditional games. Limitations : The case analysis only considers the perspective of the promoter of the event. Future research should be extended it to include the perspectives of other stakeholders. Practical implications : Although the findings indicate that the event cannot be standardised or easily reproduced, they do identify a number of factors that can favour the success of a cultural festival. Originality of the paper : As there are no published models for evaluating cultural events as good practices, the findings of this study can contribute to the open debate on this topic.
Are GPUs Non-Green Computing Devices?

With energy consumption emerging as one of the biggest issues in the development of HPC (High Performance Computing) applications, the importance of detailed power-related research works becomes a priority. In the last years, GPU coprocessors have been increasingly used to accelerate many of these high-priced systems even though they are embedding millions of transistors on their chips delivering an immediate increase on power consumption necessities. This paper analyzes a set of applications from the Rodinia benchmark suite in terms of CPU and GPU performance and energy consumption. Specifically, it compares single-threaded and multi-threaded CPU versions with GPU implementations, and characterize the execution time, true instant power and average energy consumption to test the idea that GPUs are power-hungry computing devices.
Can we explain the observed methane variability after the Mount Pinatubo eruption

Abstract. The CH4 growth rate in the atmosphere showed large variations after the Pinatubo eruption in June 1991. A decrease of more than 10 ppb yr−1 in the growth rate over the course of 1992 was reported, and a partial recovery in the following year. Although several reasons have been proposed to explain the evolution of CH4 after the eruption, their contributions to the observed variations are not yet resolved. CH4 is removed from the atmosphere by the reaction with tropospheric OH, which in turn is produced by O3 photolysis under UV radiation. The CH4 removal after the Pinatubo eruption might have been affected by changes in tropospheric UV levels due to the presence of stratospheric SO2 and sulfate aerosols, and due to enhanced ozone depletion on Pinatubo aerosols. The perturbed climate after the eruption also altered both sources and sinks of atmospheric CH4. Furthermore, CH4 concentrations were influenced by other factors of natural variability in that period, such as El Nino–Southern Oscillation (ENSO) and biomass burning events. Emissions of CO, NOX and non-methane volatile organic compounds (NMVOCs) also affected CH4 concentrations indirectly by influencing tropospheric OH levels. Potential drivers of CH4 variability are investigated using the TM5 global chemistry model. The contribution that each driver had to the global CH4 variability during the period 1990 to 1995 is quantified. We find that a decrease of 8–10 ppb yr−1 CH4 is explained by a combination of the above processes. However, the timing of the minimum growth rate is found 6n9 months later than observed. The long-term decrease in CH4 growth rate over the period 1990 to 1995 is well captured and can be attributed to an increase in OH concentrations over this time period. Potential uncertainties in our modelled CH4 growth rate include emissions of CH4 from wetlands, biomass burning emissions of CH4 and other compounds, biogenic NMVOC and the sensitivity of OH to NMVOC emission changes. Two inventories are used for CH4 emissions from wetlands, ORCHIDEE and LPJ, to investigate the role of uncertainties in these emissions. Although the higher climate sensitivity of ORCHIDEE improves the simulated CH4 growth rate change after Pinatubo, none of the two inventories properly captures the observed CH4 variability in this period.
ORCHESTRA: an asyncrhonous non-blocking distributed GVT algorithm

Taking advantage of high computing capabilities of modern distributed architectures is fundamental to run large-scale simulation models based on the Parallel Discrete Event Simulation (PDES) paradigm. In particular, by exploiting clusters of modern multi-core architectures it is possible to efficiently overcome both the power and the memory wall. This is more the case when relying on the speculative Time Warp simulation protocol. Nevertheless, to ensure the correctness of the simulation, a form of coordination such as the GVT is fundamental. To increase the scalability of this mandatory synchronization, we present in this paper a coordination algorithm for clusters of share-everything multi-core simulation platoforms which is both wait-free and asynchronous. The nature of this protocol allows any computing node to carry on simulation activities while the global agreement is reached.
Analysis of stiffness characteristics of a new fluid bag for axial shock protection

In view of large loads being needed to protect the axial from the shock situation under small displacement and deformation, a new fluid bag for axial protection was designed in Abaqus. Hydrostatic fluid elements were used to simulate fluid. Interaction between the fluid and bag was simulated with the hydrostatic theory. Based on the finite element theory, the axial stiffness of fluid bag was calculated. The results show that the stiffness had good linearity. The difference between the simulation and experiment results is small, proving the correctness of simulation. The effects of initial bag pressure on the stiffness were discussed. The results indicate that different initial pressures have few impacts on the stiffness as well as tendency of bag pressure variations. Then the effects of bag material properties and fluid bulk modulus on the stiffness were discussed. The results show that both of them are the key factors determining the stiffness. The effects of fluid bag on the stress of a mechanism under axial shock load were discussed. The results show that the fluid bag has a good performance for axial protection.
A Synthesis of the Strategic Orientations and NGO Legitimacy in the African Economic Setting

This paper provides a synthesis of the activities, programs and services of NGOs so as to draw lines to appreciate their legitimacy and role in an African economic context. The data was collected from NGOs through a questionnaire and review of printed and on-line materials. The findings were that NGO performance is being questioned, with mixed views of their legitimacy, role, financing, operations, strategy orientations and sustainability agenda. They are however, active in various sectors, have become a force to reckon with, receive huge funding, have multiple beneficiary targets and are supplementing government services. Nonetheless, the government is at pains to accept their legitimacy and thus their relationship is still full of suspicion. By underpinning the work of NGOs and finding support from the literature of their nature and operating environment, we provide support for their economic existence. For policy makers, the paper makes key statements that will guide policy formulation and implementation, leveling the legal regimes and re-establishing grounded approaches for benefiting communities as well as taking advantage of their contribution to economic and social development. For Managers, we identify lines of thought to conclude that the NGO phenomena need to be re-conceptualized in view of the dynamic environment. While many studies have been done on NGOs, we contribute knowledge from the strategic and business management dimension.
Performance characteristics of low global warming potential R134a alternative refrigerants in ejector-expansion refrigeration system

Performance assessment of ejector-expansion vapor compression refrigeration system with eco-friendly R134a alternative refrigerants (R152a, R1234yf, R600a, R600, R290, R161, R32, and propylene) is presented for air-conditioning application. Ejector has been modeled by considering experimental data based correlations of component efficiencies to take care of all irreversibilities. Ejector area ratio has been optimized based on maximum coefficient of performance (COP) for typical air-conditioner operating temperatures. Selected refrigerants have been compared based on area ratio, pressure lift ratio, entrainment ratio, COP, COP improvement and volumetric cooling capacity. Effects of normal boiling point and critical point on the performances have been studied as well. Using ejector as an expansion device, maximum improvement in COP is noted in R1234yf (10.1%), which reduces the COP deviation with R134a (4.5% less in basic cycle and 2.5% less in ejector cycle). Hence, R1234yf seems to be best alternative for ejector expansion system due to its mild flammability and comparable volumetric capacity and cooling COP. refrigerant R161 is superior to R134a in terms of both COP and volumetric cooling capacity, although may be restricted for low capacity application due to its flammability.
A reverse-voltage protection circuit for MOSFET power switches

When MOSFET is used as a power switch, it is essential to prevent reverse current flow through the parasitic body diodes under reverse voltage condition. A new built-in reverse voltage protection circuit for MOSFETs has been developed. In this design, an area-efficient circuit is used to automatically select the proper well bias voltage to prevent reverse current under the reverse-voltage condition. This built-in reverse protection circuit has been successfully implemented in a high-side power switch application using a 0.6-/spl mu/m CMOS process. The die area of the protection circuit is only 2.63% of that of a MOSFET. The latch-up immunity is greater than +12 V and -10 V in voltage triggering mode, and greater than /spl plusmn/500 mA in current triggering mode. The protection circuit is not in series with the MOSFET switch, so that the full output swing and high power efficiency are achieved.
Genetic Algorithm Optimized X-Band Absorber Using Metamaterials

This paper presents a novel, Genetic Algorithm (GA) optimized X-band absorber using metamaterials. The unit cell of this structure consists of several square patches, each having a dimension of 2.5mm × 2.5 mm. Their positions are optimized using the GA such that the X-band absorption is maximized. Simulation results and the subsequent experimental validation affirm that the structure offers absorption of 97% from 10.42 GHz to 11.98 GHz and absorption of 90% over the entire X-band from 8GHz to 9GHz and also from 9.35 GHz to 12 GHz, with peak absorption of 99.95% at 10.52 GHz. The results are compared with the existing ones, to demonstrate the superiority of the proposed design.

Sustainability in the food supply chain: evidences from the Italian beef industry

Sustainability in supply chains is a relevant but complex topic to study, especially when considering at the same time the three pillars of sustainability, namely social, environmental and economical. In particular there are many evidences that it is not only a matter of the decisions taken by companies individually, but it is more related to how the whole supply chain, including the market and the regulator, behaves (Seuring and Muller, 2008). Given the strong differences from industry to industry, we focused on the Italian beef supply chain that is relevant for its impact on the economy, the environment and the health of people. Through a set of case studies of companies at different stages of the chain we identified the sustainability practices put in place and which are the triggers - in particular if they come from inside or outside the company - and the related implications.
Compact, combined scanning tunneling/force microscope

We have built a combined scanning tunneling and scanning force microscope. Owing to the compact design of the instrument with Nomarski type of interferometry for lever deflection sensing, we achieved excellent stability with a total rms noise of 0.03–0.04 A in a frequency bandwidth of 0.01 Hz–2 kHz and a spectral noise density of 2.0×10−4 A/ √Hz at higher frequencies (≳2 kHz) using cantilevers with compliances of ∼150 N m−1. Simultaneous measurement of constant current contours, the acting forces, and the system compliance allows separation of sample topography from electronic and elastic effects.
Survive then Thrive: Talent, Research Motivation, and Completing the Economics Ph.D.

This study investigates the completion of the Ph.D. in Economics. We use ex ante information, based solely upon reviewing a set of individual applications from former doctoral students. Estimation for determining success is done by logit, multinomial logit, and generalized ordered logit. We find that students need different skills and attributes to succeed at each distinct and sequential stage of the doctoral program. Significant determinants for passing the comprehensive exams include high GRE verbal and quantitative scores, a Masters degree, and a prior focus on economics. Research motivation and math preparation play significant roles in completing the dissertation, but having a Masters degree and economics preparation becomes insignificant. GRE scores disappear as a significant determinant for completion in the generalized ordered logit estimates, which emphasize the sequential nature of the Economics Ph.D. program.
Inclusion of yeast-derived protein in weanling diet improves growth performance, intestinal health, and anti-oxidative capability of piglets

The effects of yeast-derived protein (YP) on growth performance, intestinal health, and oxidative status of weanling piglets were investigated. A total of 80 weaned piglets (PIC 327 × 1050, 26 ± 2 days old, 6.20 ± 0.10 kg) were randomly allocated into 2 groups, 5 pens per each group and 8 piglets per each pen, receiving control diet and diet with inclusion of 4% YP at the expenses of fish meal (YP diet) for a period of 28 days. The diets were formulated to contain similar nutrient levels. Compared with control, piglets fed YP diet had mark - edly higher overall average daily growth (+14%, P < 0.05) and lower final feed conversion ratio (−8%, P < 0.01). Concentrations of serum serine, cystathionine, histidine, hydroxyproline, and urea were decreased in piglets fed YP diet (P < 0.05), whereas alanine and aspartate were increased (P < 0.01). Moreover, serum antioxidant enzyme activity (glutathione peroxidase) was markedly increased (+19%, P < 0.01) in piglets fed YP diet relative to piglets fed control diet. In addition, feeding YP diet considerably (P < 0.05) increased the copy numbers of lactobacilli and total bacteria in the colon of piglets at the end of the experiment. Furthermore, the mRNA abundance of innate immunity-related genes (TLR4, NF-κB1, and IL-6) was increased (P < 0.06) in the ileum of piglets fed YP diet. Collectively, results of this study indicated that diet with the inclusion of YP improved growth performance and partially enhanced anti-oxidative capability as well as intestinal innate immunity of weaning piglets.
Numerical Analysis of Planar Periodic Multilayer Structures by Method of Moments

Numerical analysis of planar periodic multilayer structures is often carried out with the aid the method of moments (MoM). The advantage of the technique against the other, more general methods (like FEM and FDTD) is in faster computation of reflection and transmission properties of a periodic structure. Besides of computation speed, usage of MoM typically results in lower memory requirements when compared to FEM and FDTD. The method of moments can be either formulated in the spatial or spectral domain. For analysis of periodic structures the spectral formulation is more advantageous – a discrete space spectrum (Scott, 1989). Thus, the original integral equations reduce into algebraic ones (that is double summations are being used instead of surface integrals). The disadvantage of the spectral formulation is that double summations arising in MoM formulation are slowly convergent and a high number of Floquet modes is needed for analysis of periodic structures having fine patch details inside the periodic cell or densely stacked structures. Simple spectral domain MoM codes for analysis periodic structures consider uniform mesh of cells and utilize FFT to accelerate the double summations (Cwick & Mittra, 1987; Wan & Encinar, 1995). These simple MoM codes also typically use small domain basis functions (like rooftops (Cwick & Mittra, 1987), or triangular (RWG) basis functions (Kipp & Chan, 1994)). If more general geometry is to be analyzed, then a non-uniform mesh of rectangular or quad shaped cells (Kolundzija, 1998) must be used. From the computational point of view it also highly desirable to consider use of higher order large domain basis functions for representation of surface currents. Then, the conductive currents in patches may be accurately described with a small number of unknown expansion coefficients. Solution of reflection/transmission properties of a multilayer periodic structure can be performed either directly (Wu, 1995) or by the use of a cascade approach (Mittra et. al, 1988) or (Wan & Encinar, 1995). The cascade approach is suitable for periodic structures which with a large or a medium electrical thickness of individual dielectric layers. When the electrical thickness of a particular dielectric layer becomes too small then a large number of Floquet modes must be used during the cascade process (Wan & Encinar, 1995). In such a case, which is a typical for periodic structures with microscopically thin layers (e.g. carbon fibre composite materials) the direct approach is being used. 2
Emerging topics in science: Subproject in the Kompetenzzentrum Bibliometrie

[Conclusion] We presented an approach for building clusters of scientific publications according to the information given by their title, authors and reference list and for selecting a list of ET candidates from these clusters. The approach was trained with information from the years 2000 and 2001 and evaluated for the years 2002 to 2007, which correspond to the years in our dataset in which ETs actually emerge. The information that would have to be processed manually could be reduced to less than 0.14 % of the dataset. We experienced problems because the actual relevance of the hay documents in the train and test set was still unknown. A hay document still could represent an ET that was not included in our list when creating these artificial haystacks. It could also be an outlier due to a deviant title, reference list etc. For instance, in the ET candidate list for dataset 3, there were documents (or 1-instance clusters) that dealt with automatically recognizing traffic signs and extracting validation rules from microbiological data. Such documents might indeed represent a topic that might have been established as a new scientific topic. Or they could simply represent a novel application for established methodologies. A clear trend in the ET candidate list for dataset 3 could be identified for grid systems which was then a newly established scientific topic. Our evaluation showed that even-though we included citations as a second non-textual feature for LDA, the approach was still prone to disruptions based on insufficient or misleading information in both titles and reference lists. An improvement of the clustering step in future work with further extensions of LDA would also influence and probably improve the connection step. Nonetheless, this step could be further improved with a more specific analysis of the individual connections made. Since our results were worse for more recent years, the connection step could be influenced by the sheer number of connection candidates, since for each year approximately 500 cluster candidates are added. Another factor for future work would be to investigate upon the fact that the performance for dataset 3 was significantly better than for the other datasets. All in all, the results suggest that the composition of our approach and its implementation are promising, but further investigations have to be made in terms of extensibility and appropriate evaluation environments.
Global Vegetation and Land Use: New High-Resolution Data Bases for Climate Studies

Abstract Global vegetation and land-use data bases (1° latitude by 1° longitude resolution), designed for use in studies of climate and climate change, were compiled in digital form drawing upon approximately 100 published sources complemented by a large collection of satellite imagery. The vegetation data were encoded using the UNESCO classification system; land-use data were encoded using a classification system developed by the author. The vegetation and land-use data were then integrated into a land-cover data base. Areal estimates for most ecosystems from the land-cover data base were found to be significantly different from areal estimates derived from two other global land-cover sources. Possible explanations for discrepancies among these data bases include differences in ecosystem definitions and source material used in compilation. From areal estimates of major ecosystems, derived from the new vegetation and land-cover data bases it is estimated that the total ecosystem reduction caused by agricu.
Atlas of Ancient Egypt

This important book treats an old theme - the civilization of ancient Egypt - in an entirely new way: never before has Egyptian culture been presented in the form of an atlas. In fact it is far more than an atlas in the traditional sense of the word: in addition to the many historical and topographical maps, the book contains a substantial text by two distinguished Egyptologists as well as numerous color photographs and drawings illustrating every aspect of this fascinating subject.
