Joint Descriptive Modeling (JDM) for Assembly-Aware Timber Structure Design
Authors: Lharchi Ayoub , Thomsen Mette Ramsgaard , Tamke Martin 
Published: September 2021

AbstractJoints design is an essential step in the process of designing timber structures. Complex architectural topologies require thorough planning and scheduling, as it is necessary to consider numerous factors such as structural stability, fabrication capabilities, and ease of assembly. This paper introduces a novel approach to timber joints design that embed both fabrication and assembly considerations within the same model to avoid mistakes that might cause delays and further expenses. We developed a workflow that allows us to identify the fundamental data to describe a given joint geometry, machine-independent fabrication procedures, and the assembly sequence. Based on this, we introduce a comprehensive descriptive language called Joint Descriptive Model (JDM) that leverages industry standards to convert a joint into a usable output for both fabrication and assembly simulations. Finally, we suggest a seed of a joint’s library with some common joints.
A self-consistent framework of topological amplitude and its SU(N) decomposition
Authors: Wang Di , Jia Cai-Ping , Yu Fu-Sheng 
Published: September 2021

Abstract
We propose a systematic theoretical framework for the topological amplitudes of the heavy meson decays and their SU(N) decomposition. In the framework, the topologies are expressed in invariant tensors and classified into tree- and penguin-operator-induced diagrams according to which four-quark operators, tree or penguin, being inserted into their effective weak vertexes. The number of possible topologies contributing to one type of decay can be counted by permutations and combinations. The Wigner-Eckhart theorem ensures the topological amplitudes under flavor symmetry are the same for different decay channels. By decomposing the four-quark operators into irreducible representations of SU(N) group, one can get the SU(N) irreducible amplitudes. Taking the D → PP decay (P denoting a pseudoscalar meson) with SU(3)F symmetry as an example, we present our framework in detail. The linear correlation of topologies in the SU(3)F limit is clarified in group theory. It is found there are only nine independent topologies in all tree- and penguin-operator-induced diagrams contributing to the D → PP decays in the Standard Model. If a large quark-loop diagram, named TLP, is assumed, the large ∆ACP and the very different D0→ K+K− and D0→ π+π− branching fractions can be explained with a normal U-spin breaking. Moreover, our framework provides a simple way to analyze the SU(N) breaking effects. The linear SU(3)F breaking and the high order U-spin breaking in charm decays are re-investigated in our framework, which are consistent with literature. Analogous to the degeneracy and splitting of energy levels, we propose the concepts of degeneracy and splitting of topologies to describe the flavor symmetry breaking effects in decay. As applications, we analyze the strange-less D decays in SU(3)F symmetry breaking into Isospin symmetry and the charm-less B decays in SU(4)F symmetry breaking into SU(3)F symmetry.

AbstractThere is a scarcity of long-term groundwater hydrographs from sub-Saharan Africa to investigate groundwater sustainability, processes and controls. This paper presents an analysis of 21 hydrographs from semi-arid South Africa. Hydrographs from 1980 to 2000 were converted to standardised groundwater level indices and rationalised into four types (C1–C4) using hierarchical cluster analysis. Mean hydrographs for each type were cross-correlated with standardised precipitation and streamflow indices. Relationships with the El Niño–Southern Oscillation (ENSO) were also investigated. The four hydrograph types show a transition of autocorrelation over increasing timescales and increasingly subdued responses to rainfall. Type C1 strongly relates to rainfall, responding in most years, whereas C4 notably responds to only a single extreme event in 2000 and has limited relationship with rainfall. Types C2, C3 and C4 have stronger statistical relationships with standardised streamflow than standardised rainfall. C3 and C4 changes are significantly (p < 0.05) correlated to the mean wet season ENSO anomaly, indicating a tendency for substantial or minimal recharge to occur during extreme negative and positive ENSO years, respectively. The range of different hydrograph types, sometimes within only a few kilometres of each other, appears to be a result of abstraction interference and cannot be confidently attributed to variations in climate or hydrogeological setting. It is possible that high groundwater abstraction near C3/C4 sites masks frequent small-scale recharge events observed at C1/C2 sites, resulting in extreme events associated with negative ENSO years being more visible in the time series.
Inflation nach Corona: Sind die Sorgen berechtigt?
Authors:   ZG Überblick
Published: September 2021

ZusammenfassungIm August 2021 wird die deutsche Inflationsrate voraussichtlich auf 3,9 % steigen. Ein Teil davon dürfte einmaligen oder vorübergehenden Effekten geschuldet sein. Hierzu zählen in Deutschland vor allem die Rücknahme der Mehrwertsteuersenkung, die Ausweitung der CO2-Bepreisung sowie Preisanstiege durch die Knappheit von Rohstoffen und Vorprodukten. Dennoch mag es strukturelle Gründe für eine steigende Inflation geben. So werden zum Teil die lockere Geldpolitik und das neue Inflationsziel der EZB für höhere Inflationsrisiken verantwortlich gemacht. Außerdem führt die expansive Fiskalpolitik der neuen US-Administration zu höheren Preissteigerungsraten in den USA. Ob die Möglichkeit einer Lohn-Preis-Spirale besteht und ob die Inflationsmessung verbesserungsfähig ist, wird ebenfalls im Rahmen dieses Zeitgesprächs diskutiert.

Financing Energy Innovation: Internal Finance and the Direction of Technical Change
Authors: Noailly Joëlle , Smeets Roger 
Published: September 2021

AbstractAchieving the goals of the Paris Agreement and of climate neutrality by 2050 in the European Union will require mobilizing financial investments towards clean energy innovation. This study examines the role of internal finance (cash flows and cash holdings) and financing constraints for innovation in energy technologies. We construct a dataset for 1,300 European firms combining balance-sheet information and patenting activities in renewable (REN) and fossil-fuel (FF) technologies and estimate the sensitivity of patenting activities to firms’ internal finance. We use count estimation techniques and control for a large set of firm-specific characteristics and market developments in REN and FF technologies. We find that patenting activities of firms specialized in REN innovation are significantly more sensitive to a shock in cash flows than firms specializing in FF innovation. Hence, our results emphasize that innovative firms in clean energy may be particularly vulnerable to financing constraints. We discuss the implications of these results for energy transition policies aiming to redirect finance towards clean energy R&D.
Climate Uncertainty, Real Possibilities and the Precautionary Principle
Authors: Hopster Jeroen 
Published: September 2021

AbstractA challenge faced by defenders of the precautionary principle is to clarify when the evidence that a harmful event might occur suffices to regard this prospect as a real possibility. Plausible versions of the principle must articulate some epistemic threshold, or de minimis requirement, which specifies when precautionary measures are justified. Critics have argued that formulating such a threshold is problematic in the context of the precautionary principle. First, this is because the precautionary principle appears to be ambiguous about the distinction between risk and uncertainty: should the principle merely be invoked when evidential probabilities are absent, or also when probabilities have low epistemic credentials? Secondly, defenders of the precautionary principle face an aggregation puzzle: in judging whether or not the de minimis requirement has been met, how should first-order evidential probabilities and their second-order epistemic standing be aggregated? This article argues that the ambiguity can be resolved, and the epistemological puzzle can be solved. Focusing on decisions in the context of climate uncertainty, I advance a version of the precautionary principle that serves as a plausible decision rule, to be adopted in situations where its main alternative—cost–benefit analysis—does not deliver.
Mating Market and Dynamics of Union Formation
Authors: Corti Giulia , Scherer Stefani 
Published: September 2021

AbstractThe paper investigates the relationship between structural partner market constraints and the timing and educational sorting of unions in Germany (1985–2018). We integrate the literature on the effect of the reversed gender gap in education on educational assortative mating, with a focus on mating dynamics and the measurement of the partner market over the life course. We concentrate on two particular educational groups, low-educated men and highly educated women, those with worsening mating prospects and more subject to experience hypogamous unions. Our results show that the local education-specific mating squeeze influences union formation, its timing, and educational sorting. Indeed, for the two groups, the increasing supply of highly educated women in the partner market increases the likelihood of remaining single or establishing an hypogamous union, where she is higher educated than he. In line with search theory, we find the effects of the mating squeeze to become particularly visible after people turn 30 years of age. This is true for the risk of remaining single and forming an hypogamous union. We underline the necessity to study assortative mating and union formation from a dynamic perspective, taking into account changing structural conditions during the partner search process.
Optimally rescheduling jobs with a Last-In-First-Out buffer

Published: September 2021

AbstractThis paper considers single-machine scheduling problems in which a given solution, i.e., an ordered set of jobs, has to be improved as much as possible by re-sequencing the jobs. The need for rescheduling may arise in different contexts, e.g., due to changes in the job data or because of the local objective in a stage of a supply chain that is not aligned with the given sequence. A common production setting entails the movement of jobs (or parts) on a conveyor. This is reflected in our model by facilitating the re-sequencing of jobs via a buffer of limited capacity accessible by a LIFO policy. We consider the classical objective functions of total weighted completion time, maximum lateness and (weighted) number of late jobs and study their complexity. For three of these problems, we present strictly polynomial-time dynamic programming algorithms, while for the case of minimizing the weighted number of late jobs NP-hardness is proven and a pseudo-polynomial algorithm is given.

AbstractUnderstanding speech in the presence of acoustical competition is a major complaint of those with hearing difficulties. Here, a novel perceptual learning game was tested for its effectiveness in reducing difficulties with hearing speech in competition. The game was designed to train a mixture of auditory processing skills thought to underlie speech in competition, such as spectral-temporal processing, sound localization, and auditory working memory. Training on these skills occurred both in quiet and in competition with noise. Thirty college-aged participants without any known hearing difficulties were assigned either to this mixed-training condition or an active control consisting of frequency discrimination training within the same gamified setting. To assess training effectiveness, tests of speech in competition (primary outcome), as well as basic supra-threshold auditory processing and cognitive processing abilities (secondary outcomes) were administered before and after training. Results suggest modest improvements on speech in competition tests in the mixed-training compared to the frequency-discrimination control condition (Cohen’s d = 0.68). While the sample is small, and in normally hearing individuals, these data suggest promise of future study in populations with hearing difficulties.
A Novel Process for Intercalating Alkylammonium Ions in a Thai Bentonite and its Effect on Adsorption Performance

Published: September 2021

AbstractThe organization of organic species on the ordered structures of clays and clay minerals is one way to produce inorganic-organic hybrids with controlled microstructures and properties. The reactions of the adsorbed species and their arrangement on the clay surfaces can be guided by the choice of clay and of adsorbed species. The purpose of the present study was to intercalate alkylammonium ions into a Thai bentonite and to study the effect on dye-adsorption efficiency. A series of alkylammonium ions, CnH2n+1NH3+ (n = 8, 10, 12, or 18), was incorporated into the interlayer spaces of a natural bentonite by mixing an aqueous dispersion of bentonite with an aqueous solution of protonated alkylamines at room temperature. The basal spacings of the intercalation compounds varied depending on the alkyl chain lengths and the amount of alkylammonium ions. The alkylammonium ions adsorbed formed lateral monolayer, bilayer, pseudo-trimolecular layer, paraffin-type monolayer, and/or paraffin-type bilayer structures. The adsorption efficiency of alkylammonium-bentonites was determined using batch adsorption experiments of rhodamine 6G from a water-ethanol solution; the greatest efficiency was 87% while that of the bare bentonite was 47%. The loading amount and the arrangement of the intercalated alkylammonium ions in the interlayer spaces, as well as the specific surface area and pore volume, played important roles in the adsorption efficiency of alkylammonium-bentonite. The adsorption equilibrium data for rhodamine 6G on the best adsorbent were interpreted using the Langmuir isotherm model and a pseudo-second order kinetics model. The adsorption efficiency of the adsorbent decreased by only 17% after five runs.
Understanding the socioeconomic determinants of adoption of climate-smart agricultural practices among smallholder potato farmers in Gilgil Sub-County, Kenya

Published: September 2021

AbstractBesides climate-smart agriculture’s (CSA) potential to meet the world’s increasing food demands in the face of climate variability through sustainably increasing food production, its acceptance among farmers is still low. This could be partly because of limited insight into the contextual underpinnings of its uptake. Therefore, the purpose of this study was to establish the relationship between selected socioeconomic factors and the adoption of CSA in Gilgil Sub-County. This study’s results were attained from a binary logistic regression model, using a sample of 120 smallholder potato farmers in two wards of Gilgil Sub-County of Nakuru County, Kenya. An analysis of the five hypothesized explanatory socioeconomic variables contained in the model disclosed that a relationship between socioeconomic factors and adoption of CSAPs was statistically significant at a 5% level of significance (χ2 = 17.966, df = 5, p < 0.05). It further revealed that only two variables had a significant relationship with the adoption of CSAPs. Among these, included gender which was negative and statistically significant at a 5% level of significance (Wald χ2 = 6.701, df = 1, p < 0.05) and annual farm income, which was positive and statistically significant at a 5% level of significance (Wald χ2 = 8.402, df = 1, p < 0.05). Therefore, securing access to vital resources for women farmers is indispensable to enhance their capacity and compliance to adjust production methods in response to climate change. Facilitating increased farm output and income among the farmers is greatly recommended.
A new narrative for sustainability: Exploring biogas plants as ‘first movers’ in raising energy awareness
Authors: Chodkowska-Miszczuk Justyna 
Published: September 2021

AbstractIt is not only worth talking about the chances of survival in the fight against emerging environmental and socio-economic threats, but it is necessary to use all possible means to influence public awareness. It is awareness that shapes our attitudes and literacy. The core of these tools is cross-sectoral place-based education. This raises the question of the role of new energy actors in the education process. As ‘first movers’, they have enormous power in the local community. Are they therefore merely energy producers, or perhaps, using their position, are they actively involved in creating local energy behaviours? A combination of social research methods including qualitative studies helped respond to this question. As the study shows, an opportunity for effective education is contextualisation, embedding educators in the local social structure and including first movers – energy producers – in this process. Biogas entrepreneurs transpose the knowledge of renewable energy – a globally known issue – to the local level. The provision of comprehensive education requires institutional support focused on building partnerships between policy makers, teachers and practitioners, enabling not only trans-sectoral contact but also the exchange of experience.
‘FOR THEMISTOCLES OF PHREARRHIOI, ON ACCOUNT OF HONOUR’: OSTRACISM, HONOUR AND THE NATURE OF ATHENIAN POLITICS
Authors: Barbato Matteo 
Published: September 2021

AbstractThis article offers a new interpretation of the Athenian institution of ostracism and explores its significance for our understanding of democratic politics. A popular scholarly trend interprets ostracism as an instrument for pursuing (or regulating) conflict among aristocratic politicians, in accordance with a view of Athenian democracy as dominated by a restricted elite competing for power and prestige. This article aims to reassess this picture by investigating ostracism in the light of recent studies of honour, which have stressed honour's potential for balancing competition and cooperation within communities. By using the ostracism of Themistocles as a case study, it argues that ostracism was a manifestation of an institutionalized concern for honour in Athenian democracy. On the one hand, ostracism could punish politically active citizens who, in excessively enhancing their own honour, failed to respect democratic equality. On the other, it could be employed for tackling shameful behaviour which placed the agent below the community's standards of honour. The article then sets ostracism against Athens’ broader institutional framework and argues that Athenian democracy was not so much concerned with policing intra-elite conflict as much as it was designed to foster a balance between competitive and cooperative values and ensure broad participation in the political domain.
William Gore: A Puseyite in Parramatta
Authors: Willson Robert 
Published: September 2021

AbstractThis article examines the way one nineteenth-century clergyman of the Church of England in Australia, William Gore, was influenced by the Oxford Movement. Gore was the incumbent of the parish of All Saints Church, North Parramatta in Sydney. He implemented liturgical practices valued by the Oxford Movement, including wearing a surplice to preach rather than a Geneva gown, reading the Offertory sentences in the service of Holy Communion in the Book of Common Prayer, celebrating the Holy Communion on the saints days set in the Prayer Book and placing a cross on the holy table. He was supported by his bishop, William Grant Broughton. The reaction from parishioners was surprise, shock and opposition and he was branded as a ‘Puseyite’. This article uses local primary material, including press reports of parish meetings, to describe the reactions of parishioners in parish meetings against Gore’s liturgical uses. Gore’s activities are assessed as an important early example of the Oxford Movement’s influence in the Church of England in Australia. Gore’s practices, discussed in the public domain, provide evidence that the Oxford Movement was beginning to transform the nineteenth-century liturgical worship of the Church of England in Australia.

AbstractCholangiocarcinoma (CCA), a lethal malignancy of the biliary epithelium, is the second most common primary liver cancer. The poor prognosis of CCA is due to the high rate of tumour invasion and distant metastasis. We found that the RNA-binding protein LIN28B, a known regulator of microRNA biogenesis, stem cell maintenance, and oncogenesis, is expressed in a subpopulation of CCA patients. To further investigate the potential role of LIN28B in CCA pathogenesis, we studied the effect of LIN28B overexpression in the cholangiocyte cell line MMNK-1 and cholangiocarcinoma cell lines HuCCT-1 and KKU-214. Here, we show that enhanced LIN28B expression promoted cancer stem cell-like properties in CCA, including enhanced cell migration, epithelial-to-mesenchymal transition (EMT), increased cell proliferation and spheroid formation. Proteomic analysis revealed TGF-β-induced protein (TGFBI) as a novel LIN28B target gene, and further analysis showed upregulation of other components of the TGF-β signalling pathway, including TGF-β receptor type I (TGFBRI) expression and cytokine TGFB-I, II and III secretion. Importantly, the small molecule TGF-β inhibitor SB431542 negated the effects of LIN28B on both cell migration and clonogenic potential. Overexpression of TGFBI alone promoted cholangiocarcinoma cell migration and EMT changes, but not spheroid formation, suggesting that TGFBI partially contributes to LIN28B-mediated aggressive cell behaviour. These observations are consistent with a model in which TGF-β and LIN28B work together to form a positive feedback loop during cholangiocarcinoma metastasis and provide a therapeutic intervention opportunity.
