Determining Learning Outcomes Relevant for Logistics Higher Education on Sustainability and Industry 4.0

: The ambitious goals of the European Union require companies to transform themselves into sustainable and smart. To do so, for example, in the logistics field, employees who will know how to implement green transport and logistics and how to establish smart systems based on a higher level of digital maturity are needed. This article lists 51 essential topics from Sustainability, Industry 4.0, Logistics 4.0, and Digitalisation areas, further supported by 127 unique learning outcomes gathered through a multi - stage international Delphi study including practitioners and academics. Experts from 6 countries participating in the study first identified the most important topics from the field and the connected learning outcomes in the following rounds, and consequently achieved consensus on the most important learning outcomes that the future workforce in the logistics sector should have. Supporting the logistics sector with a workforce educated based on this framework should help it reach the European Union’s strategic goals.
Miniaturized substrate integrated waveguide 5G LTCC bandpass filter exploiting capacitive loaded cavities

In this article, a compact bandpass filter with a pair of transmission zeros exploiting capacitive loaded cavities is presented. The proposed filter structure is mainly composed of coplanar waveguide (CPW) feeding structures and four substrate integrated waveguide (SIW) resonators. The size of the filter has been greatly reduced due to the capacitive loaded circle metallic septum and the vertical coupling of stacked cavities in three dimensional structures by low temperature co‐fired ceramic technology. The filter not only achieves the advantages of high‐selectivity, a much wider upper stopband bandwidth, but also realizes a miniaturized volume of 3.35 × 2.10 × 0.66 mm3. The simulated and measured results show the bandpass filter achieves a center frequency of 28 GHz with 3 dB fractional bandwidth of 8%. The filter is suitable for application in 5G wireless communication.

Spatial and Spatio-temporal Epidemiology

The rapid spread of COVID-19 worldwide led to the implementation of various non-pharmaceutical interven- tions to limit transmission and hence reduce the number of infections. Using telecom-operator-based mobility data and a spatio-temporal dynamic model, the impact of mobility on the evolution of the pandemic at the level of the 581 Belgian municipalities is investigated. By decomposing incidence, particularly into within-and between-municipality components, we noted that the global epidemic component is relatively more important in larger municipalities (e.g., cities), while the local component is more relevant in smaller (rural) municipalities. Investigation of the effect of mobility on the pandemic spread showed that reduction of mobility has a significant impact in reducing the number of new infections.
Abiotic controls on windthrow and forest dynamics in a coastal temperate rainforest, Kuiu Island, southeast Alaska

The pristine coastal temperate rainforests in southeast Alaska present a unique opportunity to study natural patterns disturbance relatively devoid of human influence. We investigated the role of 4 abiotic factors in controlling patterns of long-term windthrow on the forested landscape. Our objectives were to I) test the hypothesis that long-term patterns of windthrow can be predicted spatially at the landscape scale using four abiotic factors; exposure to prevailing storm direction, slope, elevation and soil stability; and 2) compare stand age and structural characteristics in windthrow-prone and windthrowprotected landscapes. We used photointerpretation to identify forest patches that were of windthrown origin on Kuiu Island, southeast Alaska. A. spatially-' explicit logistic model was then built from the windthrow data, and other GIS data layers, based on elevation, slope, exposure to prevailing storm winds and soil type. Landform influence on patterns of windthrow was examined by evaluating model classification error rates by landform type. The model was validated by extrapolating the Kuiu model coefficients to nearby Zarembo Island, and comparing model predictions to an independent large-scale windthrow data set. The model correctly classified 72% of both windthrown and non-windthrown forest. Field plots collected in most and least windthrowprone landscapes on Kuiu suggest that structural and age characteristics as well as forest development stages (stem-exclusion, understory-reinitiation, or gap-phase forests) vary with probability of windthrow occurrence across the landscape. We conclude that small-scale (partial-canopy) disturbance processes predominate in areas least-prone to windthrow, and that large-scale stand-replacement disturbance processes predominate in areas most-prone to windthrow. Our work suggests that a long-term wind damage gradient exists on Kuiu Island, which can be predicted spatially. Previous to this research forest dynamics in coastal temperate rainforests were thought to be regulated primarily by gap-phase disturbance processes. We conclude there is less naturally occurring old-growth forest regulated by gap-phase succession than previously believed. To date, more than 50% of the timber harvest on Kuiu Island has been located in areas where gap-phase processes (old-growth forests) predominate, only 14% has been in areas where stand-replacement processes predominate. Future management activities should be tailored to consider long-term natural disturbance patterns to better maintain ecosystem function. In areas least-prone to catastrophic storm damage, individual tree or group tree selection may be more appropriate. Two-aged management may be more appropriate in areas most-prone to catastrophic storm effects.
Towards greater systemisation in CI research: An exploration of social development as a framework for comparison and understanding

The theme of complexity alludes to the difficulties community informatics (CI) researchers face when analysing use of ICTs by communities. In response, de Moor (2009; 2009) and Stillman (2010) identify the need for greater systemisation of CI research that enables complex socio-technical processes to be analysed over multiple cases. The principle by which such systemisation should occur is open to debate. It seems improbable that a single theoretical approach, at least in the short term, is going to satisfy everyone as greater systemisation is pursued. The paper suggests that, as a first step, efforts should be devoted to better appreciation of philosophical principles that underpin theories and their often-unarticulated assumptions. In a spirit of inclusivity, the paper therefore argues that efforts to systemise CI research should seek to include a variety of cases in the study of CI and relate such cases on the basis of a common framework. As an example of such a framework, the work of Hall and Midgley (2004) in social development is provided to demonstrate the means by which different cases can be understood and compared in relation to three dominant areas of discourse in social development: populism (communitarian), Enterprise and Statist. The paper explains this framework using research carried out in relation to community technology centres (CTCs) in regional New South Wales, Australia. While Hall and Midgley's framework reflects three areas of discourse, they leave the way open for additional areas of discourse to be included, namely those derived from indigenous knowledge.
Vibrational Analysis of Fullerene Hydrides Using AIREBO Potential

In this paper, the vibrational properties of fullerene hydrides with the chemical formula C60H2n are investigated using a method based on the potential energy of the molecule. The potential used in this methodology is AIREBO (Adaptive Intermolecular Reactive Empirical Bond Order). Using this interatomic potential, some of the most important frequencies of the fullerene hydrides, such as the breathing mode frequency, were calculated and then analyzed. It was observed that in addition to the number of hydrogen atoms in the structure, their position on the C60 cage has a significant effect on the natural frequency corresponding to a particular mode shape. The results obtained by this method have been compared and validated with quantum mechanics and experimental observations. The simulations results demonstrate that the proposed method is capable of calculating the vibrational properties of fullerene hydrides with high precision and low computational cost.
Comphrensive resource balance for ethanol produced from corn and sugarcane

Due to the increase in price of fossil fuels and climate change caused by Greenhouse Gas (GHG) emissions, many countries around the world are trying to produce alternative transportation fuels. Ethanol has emerged as a popular alternative to fossil fuels, especially, in countries such as the U.S. and Brazil. Different feed stocks are being used to produce ethanol, with corn and sugarcane as the major crops currently being converted into ethanol. Ethanol production requires considerable resources. To date energy input has been studied extensively. However, only limited data is available on other resources used, such as water and land, and the environmental degradation due to waste generated and GHG emissions. The primary objective of this study is to estimate the resource balance for ethanol produced from corn and sugarcane in different climatic zones: temperate, dry and tropical for corn, and tropical and dry for sugarcane. The results of the study indicate that ethanol produced from sugarcane uses less or comparable resources compared to ethanol produced from corn. The estimates of Net Energy Value (NEV) for corn ethanol were between -1,656 and 6,305 Btu per gallon, while those of sugarcane ethanol were between 57,606 and 61,319 Btu per gallon for different climatic zones considered in this study. Moreover, the highest estimated water requirements, for dry climate, were 2,650 and 2,050 gallons of water per gallon of ethanol for corn and sugarcane ethanol, respectively. Results for carbon dioxide released to the environment from corn ethanol with respect to fossil fuels show a reduction of 44, 26 and 51 percent for tropical, dry and temperate climate zones, respectively. On the other hand, results show a reduction of 62 and 57 percent for carbon dioxide emissions from ethanol produced from sugarcane in tropical and dry climates, respectively. However, when land use change is accounted for, results indicate a significant increase in carbon dioxide emissions, referred to as carbon debt. Considering the reduction of carbon dioxide emissions resulting from ethanol and the debt amount, the payback time will be very long. Results of this study indicate that if forest is converted into a one cycle cropland, corn ethanol will require a payback period of 300, 672 and 210 years, for tropical, dry and temperate climate zones, respectively. If grassland is converted into cropland, corn ethanol will require a payback period of 112, 242 and 82 years, for tropical, dry and temperate climate zones, respectively. Similarly for sugarcane ethanol, when forests are converted into cropland, the payback period is 102 and 132 years, for tropical and dry climate zones, respectively. If grassland is converted into cropland, the payback period for sugarcane ethanol is 38 and 50 years, for tropical and dry climate zones, respectively. In addition, each gallon of corn ethanol requires about 156, 206 and 135 square feet of land for tropical, dry and temperate climates, respectively. Sugarcane ethanol requires about 75 and 91 square feet for…
Supermarket purchases and the dietary patterns of households in Guatemala

"Very limited empirical analyses are done on evaluating how changes in the retail environment affect diet and health status of consumers, especially in developing countries. The major objective of this study is to shed some light on some of these neglected but crucial issues. The study examines the impact of supermarket purchases on dietary practices (defined as the calorie share of different food groups) of Guatemalan households using the 2000 Guatemalan household survey. I use an instrumental variable method to take into account the potential endogeneity of the supermarket-purchase variable in the calorie share equations. The results of the study reveal that supermarket purchases increase the share that highly and partially processed food items, such as pastries, cookies, crackers, chocolate, ice cream, and so forth, make of total calories, at the expense of staple food items such as corn and beans. Since most processed foods contain disproportionately high amounts of added fat, sugar, and salt, and since supermarkets are expanding rapidly, different policy measures should be developed to ensure that supermarkets have a "healthier" impact on diets.

Quantification of flows generated by the hydromedusa Aequorea victoria : a Lagrangian coherent structure analysis

Most oblate medusae use flow generated during swimming to capture prey. Quantification of their interactions with surrounding fluid is necessary to understand their feeding mechanics and to develop models to predict their predatory impact. In the present study, we quantified how the hydromedusa Aequorea victoria interacts with both its surrounding fluid and prey. The fluid interactions were examined in the laboratory and in natural field settings using digital particle image velocimetry (DPIV) measurements. The laboratory DPIV data were used to compute finite-time Lyapunov exponent (FTLE) fields, and Lagrangian coherent structures (LCS) were extracted from the FTLE fields. The laboratory LCS analysis demonstrated that swimming A. victoria only encounter discrete packets of fluid originating upstream of the medusan bell. Based on the size of these packets, we estimated that the A. victoria examined have the potential to clear 11.4 l h–1. Used in conjunction with measured prey capture efficiencies, we estimated potential clearance rates on different prey types. These hydrodynamically based clearance rate estimates are consistent with previously measured empirical clearance rate estimates. Velocity vector and shear fields also suggested that the feeding current created by A. victoria may be more suitable for encountering copepods than previously thought. Although still preliminary, in situ DPIV data indicate that natural background flows may alter the encounter process from what is observed in still-water laboratory conditions.
Nitrogen fixation in the western English Channel (NE Atlantic Ocean)

In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has been demonstrated by 2 independent measurements: 15 N-N2 incorporation and nifH identification in the DNA and expressed messenger RNA (mRNA). At 2 stations in the western English Channel, bulk waters were incubated with 15 N-N2. At the high levels of particulate nitrogen (≤11.5 µmol N l -1 ), absolute fixation rates of 18.9 ± 0.01 and 20.0 nmol N l -1 d -1 were determined. While a caveat must accompany the magnitude of the rates presented due to the limited number of data, the presence and activity of diazotrophic organisms in these waters is of ecological significance and may affect current attitudes to nitrogen and carbon budgets. In particular, our estimate of the rate of N fixation (0.35 mmol N m -2 d -1 ) is comparable to that of denitrification rates in UK shelf seas. Molecular analy- sis identified a diversity of expressed nifH genes, and 21 different prokaryotic nifH transcripts were identified.
Robustness in Multimodal Learning under Train-Test Modality Mismatch

Multimodal learning is defined as learning over multiple heterogeneous input modalities such as video, audio, and text. In this work, we are concerned with understanding how models behave as the type of modalities differ between training and deployment, a situation that naturally arises in many applications of multimodal learning to hardware platforms. We present a multimodal robustness framework to provide a systematic analysis of common multimodal representation learning methods. Further, we identify robustness short-comings of these approaches and propose two intervention techniques leading to 1 . 5 × - 4 × robustness improvements on three datasets, AudioSet, Kinetics-400 and ImageNet-Captions. Finally, we demonstrate that these interventions better utilize additional modalities, if present, to achieve competitive results of 44 . 2 mAP on AudioSet 20K.
Governance and Vulnerability in Small Island States

In general, communities in Small Island Developing States (SIDS) are socioeconomically and environmentally vulnerable due to their geographical and ecological conditions. Small archipelagic states are even more vulnerable in terms of natural and human-induced disasters because of their fragmentation, isolation and smallness. Good governance is a vital precondition to reduce the vulnerability of these states. This study examines these two correlated phenomena, governance and vulnerability, their inter-related implications and complications, and the role of governance in reducing vulnerability of SIDS and their island communities. It also proposes some practical remedies for the challenges of these communities. Qualitative research using multiple methods, secondary data collection, informal semi-structured interviews, open-ended discussions, informal conversational interviews and direct observations, was carried out through case studies of two archipelagos, the republics of Maldives and Vanuatu. In addition, the New Zealand local government model with a focus on Bay of Plenty Region was also studied in order to seek policy models and best practices from a developed state. The field inquiry revealed that an effective local governance system is vitally important to address socio-economic and environmental vulnerability of these archipelagic communities. Neither a rigid centralised system, like the Maldives, nor a decentralised system, as in the case of Vanuatu, was found to be appropriate and effective unless certain functions are delegated and local authorities are made selfreliant, financially and functionally self-sufficient and aware of their responsibilities through education, while community members are empowered by providing more socio-economic opportunities. Based on the research findings, the thesis highlights four key causes of increasing vulnerability in these communities: absence of a reliable outreach mechanism for emergency management, lack of a strong local governance system, scarcity of socioeconomic resources and opportunities, and inadequate socio-economic infrastructures. The thesis suggests possible ways forward by proposing a four tier cluster approach with a decentralised emergency management system and local governance model. The transient vulnerability (natural or weather related disasters) of these archipelagic communities cannot be addressed unless their chronic vulnerability, lack of socio-economic opportunities, is addressed through sound local governance.
Mobilités sociales et spatiales: Parcours intergénérationnels d'après les mariages genevois, 1830-1880

The aim of this paper is to improve our understanding of the social intergenerational mobility in Geneva during the 19th century. We provide an indepth study of data collected from the marriage registrations acts. These documents provide us information on the spouses, but also on their parents and the witnesses. Our analysis focuses on the transitions between six social statuses defined from the professions found in the marriage Records. Since we collected all acts for married men with a name beginning with letter B, we have also in our dataset the act for the marriage of the father when he get himself also married in Geneva. This led us to split our population into those who have a father married in Geneva and those who have not. The first subpopulation corresponds to people that are established in Geneva since more than one generation, while the others are newcomers. We first show that these two subpopulations considerably differ both in their social structure and in their father-son mobility schemes. Then, focusing on the stable population, for which we have data available, we provide a mobility analysis through three generations using an original induction tree approach. Beside these strict social mobility aspects, we consider also a spatial dimension by looking at how the mobility is affected by the birthplace of the spouses. Finally, we examine the familial framework of the newlyweds, especially how the familial support and control differ between the newcomers and the more enrooted population. A detailed discussion of one large family of each of these two subpopulations enlightens their specific horizontal social mobility processes.
Observation of electroweak production of a same-sign $W$ boson pair in association with two jets in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

This Letter presents the observation and measurement of electroweak production of a same-sign $W$ boson pair in association with two jets using 36.1 fb$^{-1}$ of proton-proton collision data recorded at a center-of-mass energy of $\sqrt{s}=13$ TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed in the detector fiducial phase-space region, defined by the presence of two same-sign leptons, electron or muon, and at least two jets with a large invariant mass and rapidity difference. A total of 122 candidate events are observed for a background expectation of $69 \pm 7$ events, corresponding to an observed signal significance of 6.5 standard deviations. The measured fiducial signal cross section is $\sigma^{\mathrm {fid. }}=2.89^{+0.51}_{-0.48} \mathrm{(stat.)} ^{+0.29}_{-0.28} \mathrm{(syst.)}$ fb.
Combination of tadalafil and finasteride for improving the symptoms of benign prostatic hyperplasia: critical appraisal and patient focus

: The evidence suggests that combination therapy for benign prostatic hyperplasia (BPH)-lower urinary tract symptoms (LUTS) using an α -blocker and a 5 α -reductase inhibitor has become well accepted. The combination of daily tadalafil and an α -blocker has also demonstrated benefit. This paper addresses combination therapy with daily tadalafil and finasteride for the treatment of BPH-LUTS. Our results demonstrate that use of tadalafil and finasteride represents a logical extension of combination therapies. We analyze a landmark study by Casabé et al that demonstrates improved voiding symptoms as assessed by International Prostate Symptom Scores with a combination of tadalafil and finasteride compared with finasteride and placebo. Study patients had moderate to severe LUTS and prostate volumes  30 g. The additional benefit of improved erectile function as assessed by International Index of Erectile Function-erectile function domain scores with the addition of tadalafil was a secondary benefit. We propose that the ideal patient for combination therapy with tadalafil and finasteride has a prostate volume  30 g and desires additional benefit over monotherapy. For these men, improved erectile function without sexual side effects was a
