Should investors include commodities in their portfolios after all? New evidence

Abstract This paper investigates whether an investor is made better off by including commodities in a portfolio that consists of traditional asset classes. First, we revisit the posed question within an in-sample setting by employing mean–variance and non-mean–variance spanning tests. Then, we form optimal portfolios by taking into account the higher order moments of the portfolio returns distribution and evaluate their out-of-sample performance. Under the in-sample setting, we find that commodities are beneficial only to non-mean–variance investors. However, these benefits are not preserved out-of-sample. Our findings challenge the alleged diversification benefits of commodities and are robust across a number of performance evaluation measures, utility functions and datasets. The results hold even when transaction costs are considered and across various sub-periods. Not surprisingly, the only exception appears over the 2005–2008 unprecedented commodity boom period.
Full-time versus part-time employment: Does it influence frequency of grandparental childcare?

The impact of grandparents' employment on grandparental childcare has been examined repeatedly, but the findings have so far been inconsistent. We contend that these inconsistencies may have resulted from variations in model specification and crude measurement of employment status. Furthermore, we assert that earlier research overlooked gender differences in the ability to combine paid employment and caregiving as well as variations between maternal and paternal grandparents. We also question the causal interpretation of earlier findings that were based on cross-sectional data. We revisit the issue of the impact of the intensity of employment and analyze SHARE data from 19 countries. We find a significant positive association between part-time employment (as compared to full-time employment) and the frequency of grandparental childcare in a cross-sectional sample, but only among paternal grandmothers. Capitalizing on the panel component of SHARE, we use a within-person estimator to show that this association is unlikely to reflect a causal effect of the intensity of labor market attachment on the frequency of the care of grandchildren, but more probably results from omitted variable bias. We argue that grandparents most likely to provide (intensive) childcare are also most likely to adjust their employment in anticipation of caregiving. The paper documents the usefulness of role strain theory among grandparents and highlights that part-time jobs may reduce role conflict and may thus make grandparenting a more easily manageable experience.
Low temperature catalytic methane decomposition for cox-free hydrogen production

The world needs a disruptive technology to very quickly decarbonize the energy; the success of this technology depends heavily on its social acceptance, sustainability and fast and easy implementation. The proponents of 112CO2 believe to have this technology. Imagine that a new chemical reactor would make possible to use methane, an easy to transport and to store fuel, either fossil, renewable or synthetic, for producing COx-free hydrogen in a cost-effective way. Imagine that this approach could be implemented swiftly, taking advantage of the present infrastructure. 112CO2 project is about producing hydrogen from low temperature methane decomposition (MD), a 100 % selective reaction – CH4 → C (s) + 2 H2. The use of methane from biogas allows actively to remove CO2 from the atmosphere (negative carbon balance) but, if using fossil methane, there will be no COx emissions. 
112CO2 project aims at developing a low temperature MD catalyst, easy to regenerate and very active, > 0.45 gH2/gCat/h and stable for at least 10 000 h. 112CO2 proposes an innovative regeneration step based on the selective hydrogenation of the carbon attaching interface with the catalyst, allowing to release the coke particles and the recovery of the catalytic activity. Proponents succeed very recently to demonstrate, in a 500-h experiment, that this approach is possible and easily accomplishable. A membrane reactor, made of a stack of individual cells for producing hydrogen and a stack for pumping out this fuel cell grade hydrogen, will be developed for running at ca. 600 °C and to display > 0.05 gH2/cm3/h, an energy density comparable to the PEMFC. The proposed MD reactor is suitable for mobile as well as for stationary applications.
112CO2 project proposes also an ambitious communication strategy, aim at to involve investors, existing companies, researchers, youngsters, undergraduate and graduate students for this new technology and engage them in the urgent energy decarbonization endeavour.
Investigation of the near and far wake of a bluff airfoil model with trailing edge modifications using time-resolved particle image velocimetry

Experimental investigations on the topology and the structure of the near and far wake of a quasi-2D blunt NACA0012 airfoil cut at 80 % of the original chord length c
 master have been performed by means of time-resolved particle image velocimetry. The experiments took place in a closed-loop water tunnel at a model-thickness H-based Reynolds number of Re
 H
  = 44,000. The periodic and alternating vortex formation process at the base of the bluff model with a dimensionless frequency of Sr
 h
  = 0.2 (relating to the trailing edge height h) was investigated in detail. Subsequently, four modifications of the trailing edge geometry (broken trailing edge, square-wave base, stepped afterbody and extension of the reference model by $$\Delta c/c_{\rm master} = 7.5\,\%$$
 ) have been investigated in order to mitigate the periodic vortex formation and the alternating shedding process. In the far wake, a considerable decrease in momentum loss and resulting drag force in the range of 29 % has been achieved for this specific Reynolds number. Investigations of the time-resolved flow field proved that the periodic, alternating flow separation can be attenuated resulting in an optimized recirculation region and a low-loss wake. It can be inferred that passive flow control means like modifications of the rear end geometry of quasi-2D blunt models are a capable method to improve the flow field with respect to a minimization of momentum losses in the wake.
Highly conductive graphene ink

Graphene's unique electrical and optical properties make it ideal for a variety of applications, in particular for flexible (opto)electronic devices, such as mobile phones, tablets etc. Current flexible electronic devices are based on organic semiconducting materials with excellent current switching but poor charge carrier mobility, which result in a slow response. HiGRAPHINK aims to unlock this limitation by demonstrating the viability of graphene as additive to printed organic semiconducting materials, aiming to improve their mobility. The devices will be made into flexible active matrix arrays to drive proof of concept Organic Light Emitting Diode (OLED) displays. Combining graphene and organic semiconducting materials may significantly improve the performance of flexible active matrix arrays, enabling a range of foldable and portable consumer electronic devices
SWIMWEAR WITH FLUID DRAINING MECHANISM

An absorbent swimwear garment having a fluid draining mechanism included in the layers of the garment. The swimwear garment includes a body side liner, an outer cover, and an absorbent assembly between the body side liner and the outer cover. Between the absorbent assembly and the outer cover is a layer of water-dispersible material, such as a film or a nonwoven web, coated on a surface facing the absorbent assembly with a barrier coating. During initial product use, the absorbent swimwear garment is able to contain urine and bowel movements, similar to ordinary diapers and training pants. When the swimwear garment is submersed in swim water, such as pool or lake water, the water-dispersible material becomes soluble and allows swim watr, but not bowel movements, to drain out through the outer cover of the garment.
SOLAR COSMIC-RAY INTERACTION WITH PROTOPLANETARY DISKS: PRODUCTION OF SHORT-LIVED RADIONUCLIDES AND AMORPHIZATION OF CRYSTALLINE MATERIAL

Solar cosmic-ray (SCR) interactions with a protoplanetary disk have been invoked to explain several observations of primitive planetary materials. In our own Solar System, the presence of short-lived radionuclides (SLRs) in the oldest materials has been attributed to spallation reactions induced in phases that were irradiated by energetic particles in the solar nebula. Furthermore, observations of other protoplanetary disks show a mixture of crystalline and amorphous grains, though no correlation between grain crystallinity and disk or stellar properties have been identified. As most models for the origin of crystalline grains would predict such correlations, it was suggested that amorphization by stellar cosmic-rays may be masking or erasing such correlations. Here we quantitatively investigate these possibilities by modeling the interaction of energetic particles emitted by a young star with the surrounding protoplanetary disk. We do this by tracing the energy evolution of SCRs emitted from the young star through the disk and model the amount of time that dust grains would spend in regions where they would be exposed to these particles. We find that this irradiation scenario cannot explain the total SLR content of the solar nebula; however, this scenario could play a role in the amorphization of crystalline material at different locations or epochs of the disk over the course of its evolution.

The Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data – HOAPS-3

Abstract. The availability of microwave instruments on satellite platforms allows the retrieval of essential water cycle components at high quality for improved understanding and evaluation of water processes in climate modelling. HOAPS-3, the latest version of the satellite climatology "Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data" provides fields of turbulent heat fluxes, evaporation, precipitation, freshwater flux and related atmospheric variables over the global ice-free ocean. This paper describes the content, methodology and retrievals of the HOAPS climatology. A sophisticated processing chain, including all available Special Sensor Microwave Imager (SSM/I) instruments aboard the satellites of the Defense Meteorological Satellites Program (DMSP) and careful inter-sensor calibration, ensures a homogeneous time-series with dense data sampling and hence detailed information of the underlying weather situations. The completely reprocessed data set with a continuous time series from 1987 to 2005 contains neural network based algorithms for precipitation and wind speed and Advanced Very High Resolution Radiometer (AVHRR) based SST fields. Additionally, a new 85 GHz synthesis procedure for the defective SSM/I channels on DMSP F08 from 1988 on has been implemented. Freely available monthly and pentad means, twice daily composites and scan-based data make HOAPS-3 a versatile data set for studying ocean-atmosphere interaction on different temporal and spatial scales. HOAPS-3 data products are available via http://www.hoaps.org.
The peace park - Cross-border tourism within reach

Mount Sabotino was the scene of bloody battles during the First World War. Today the border is no longer the symbol of peoples’ division and separation, and is going to become an example of union and cooperation thanks to the creation of the Peace Park, that counts on the participation of all the twenty-two peoples who fought on the Isonzo front. The project envisages the creation of several recreational infrastructures, as well as the marking and renovation of walk paths, cycling tracks, of twenty caves and more than one hundred and fifty metres of trenches dating back to the Great War. This initiative also aims to develop joint tourist products (Mount Sabotino, Peace Park, Gastronomy - the Flavours of the Frontier, Fronts and borders) that will connect the Peace Park with the wider area of the Isonzo front. In this sense information centres and info-points are set up for visitors in Villa Bartolomei di Salcano, in the barracks of the Border Guard and at the Gorizia Local Tourist Office. The actions envisaged also include the analysis of tourist resources, the training of tourist operators, the organization and promotion of events, the creation of tourist packages (2-3-6 day stay), and the promotion of tourist packages to enhance the territory as a whole. The latter extends to both sides of the border, based on a specific marketing plan, through the support of leaflets, videos, publicity ads and commercials on radio and TV. Thanks to this presentation the cross-border area that is interested by this project highlights and acknowledges a commitment towards sustainable development and the preservation of existing natural, historical and cultural resources.
Explaining the Performance of Human Resource Management

Human resource departments increasingly use the statistical analysis of performance indicators as a way of demonstrating their contribution to organizational performance. In this book, Steve Fleetwood and Anthony Hesketh take issue with this 'scientific' approach by arguing that its preoccupation with statistical analysis is misplaced because it fails to take account of the complexities of organizations and the full range of issues that influence individual performance. The book is split into three parts. Part I deconstructs research into the alleged link between people and business performance by showing that it cannot explain the associations it alleges. Part II attributes these shortcomings to the importation of spurious 'scientific' methods, before going on to suggest more appropriate methods that might be used in future. Finally, Part III explores how HR executives and professionals understand their work and shows how a critical realist stance adds value to this understanding through enhanced explanation.

Valorizing connectivity and sustainable use of resources for successful ecosystem management policies in the Alps

GreenALPS shapes the framework for a sustainable and efficient European nature and biodiversity conservation policy for the Alps. It relies on two key projects covering essential issues how to best conserve alpine biodiversity (ECONNECT) and how to deal with the huge demand for renewable energy related impacts on nature (recharge.green). Both projects are linked and deliver(ed) essential outcomes for the future management of alpine natural assets. Nevertheless results are still too sectoral and need further efforts to reach additional key stakeholders & policy makers. A significant reduction of fragmentation of Alpine natural or semi-natural habitats is needed, calling a long-term orientated land use planning, new ways of cooperation and a precautionary approach of other key sectors The successful governance approach of pilot regions beyond protected areas will be reviewed and disseminated at the same time by capitalizing on already ongoing participatory processes in old and new PR.
Copper is an endogenous modulator of neural circuit spontaneous activity

Significance Copper is traditionally regarded as a static, tightly bound cofactor in enzymes, but emerging data link more-loosely bound pools to cell signaling. Here we use molecular imaging to identify a role for copper in the brain as a modulator of spontaneous activity of developing neural circuits. First, we directly visualized a labile, loosely bound copper pool in hippocampal neurons and retinal tissue with a newly developed Copper Fluor-3 (CF3) indicator. We then used two-photon calcium imaging as readout of spontaneous activity to show that disruption of labile copper stores by acute chelation or genetic knockdown of the CTR1 (copper transporter 1) copper channel alters the frequency and spatial propagation of neural activity. The results establish the requirement for copper in a fundamental, dynamic property of brain circuitry.
Efficient Cross Section Reconstruction on Modern Multi and Many Core Architectures

The classical Monte Carlo (MC) neutron transport employs energy lookup on long tables to compute the cross sections needed for the simulation. This process has been identified as an important performance hotspot of MC simulations, because poor cache utilization caused by random access patterns and large memory footprint makes it unfriendly to modern architectures. A former study [1] shows that such method presents little vectorization potential in a real-case simulation due to the memory-bound nature. In this paper, we revisit a cross section reconstruction method introduced by Hwang [2] to evaluate another solution. The reconstruction converts the problem from memory-bound to compute-bound. Only several variables for each resonance are required instead of the conventional pointwise table covering the entire resolved resonance region. Though the memory space is largely reduced, this method is really time-consuming. After a series of optimizations, results show that the reconstruction kernel benefits well from vectorization and can achieve 1806 GFLOPS (single precision) on a Knights Landing 7250, which represents 67% of its effective peak performance.
Developing a Stand Hazard Index for Oak Decline in Upland Oak Forests of the Ozark Highlands, Missouri

Abstract Black oak (Quercus velutina Lam.) and scarlet oak (Quercus coccinea Muenchh.)—two major components (44% of total stand basal area) of upland oak forests—are suffering severe decline and mortality in the Ozark Highlands, Missouri. However, factors influencing their survival (mortality) are not well understood. In this study we quantified how stand and tree-level predisposing factors are associated with survival of black and scarlet oaks. Sixteen-year monitoring data from the Missouri Ozark Forest Ecosystem Project (MOFEP) indicated that overall annual mortality of black and scarlet oaks averaged 2.2 and 1.7%, respectively, three to five times higher than expected (around 0.5%) for white oak, a common associate. For the first 8 years of the study (1990‐1998), survival rates of black and scarlet oaks were similar. Thereafter, the survival rate of black oak declined relative to scarlet oak. Using the classification and regression tree (CART) method we classified black oak and scarlet oak trees into seven and nine risk groups, respectively, that differed significantly in rates of tree mortality. Groups were distinguished based on tree diameter, crown class, and size relative to competitors. An oak decline and mortality hazard index was thus developed as the weighted means of risk group mortality, which can help managers prescribe species-specific silvicultural treatments to help mitigate oak decline and associated mortality.
Transnational LOGistics' Improvement through Cloud computing and innovAtive cooperative business modeLs

Located in between old Member States and emerging markets in the East, Central Europe’s logistics sector has an enormous potential to add value to the region and create an employment opportunities. Challenged by rising demands on just-in-time delivery and increasing environmental costs of cargo transport, the interoperability of logistics businesses has become a critical success factor for the competitiveness of logistics hubs. High transaction costs due to the different standards in managing software systems represent bottlenecks especially for the collaboration between small businesses and global players with own systems. Latest technological developments and applied research have demonstrated that cloud computing might be just the right solution for this problem.

In the simplest of terms, cloud computing is an IT solution, where third party hosts your IT structure on a large remote server station with you having an access to it over the internet.  And as the access to modern IT tools has been identified as a key factor in enhancing competitiveness, a highly innovative IT tool has the potential to strengthen Central Europe‘s strategic importance for cargo transport between North and South, old and new EU members and evolving East European markets.

The cloud computing can therefore help to overcome the deficit in interoperability between actors in logistics networks concerning a single hub and moreover, a multi-cloud concept facilitates their transnational collaboration, e.g. enabling collective cargo transport by sustainable means (e.g. train instead of individual road transport). The project LOGICAL is based on and further develops the „InterLogGrid“ research project, funded by the German Ministry for Education and Research,  where the cloud computing concept has been developed to overcome this bottleneck and is taking and tackling the problem on transnational level by unleashing the full potentials of a multi-cloud concept where a significant number of logistics hubs are connected virtually.
Understanding the urban travel attitudes and behavior of Tbilisi residents

Abstract In recent decades the public transport network in Tbilisi, Georgia has decayed, while the number of private automobiles has increased dramatically. This study seeks to expand our understanding of the Tbilisi population’s urban transport attitudes and behavior. It elaborates on the perceived strengths, weaknesses, and potentials of the public transport system, and seeks to understand the reasons for the increased use of private automobiles. A questionnaire survey was conducted among Tbilisi car drivers ( n =159) and public transport users ( n =163). The results show that most of the survey respondents preferred to use a private car and avoid using public transport. Particularly important factors include time issues such as schedules and frequency, plus comfort and safety issues. Tbilisi residents value their time and want to use it efficiently. Changing residents’ travel behavior will require making the public transport options competitive with the perceived advantages of the car. The study offers recommendations for more effective urban transport policy, including incentives to encourage greater use of public transport in Tbilisi.
