description: DigiTala's rating criteria: Holistic and analytic scales for assessing L2 speaking DigiTala research project developed one holistic and five analytic rating scales for assessing L2 learners speech samples. The 2020 versions were used during the Swedish rating round and 2021 version during Finnish rating rounds. The human ratings were used for training an automated scoring system. The raters recruited by the project assessed L2 Swedish and Finnish learners' speech samples online using Moodle (version 3.8.3). In addition to the criteria, the platform included assessment guidelines and benchmark samples illustrating different proficiency levels. An hour-long rater training was organized using Zoom. The rating criteria were developed for research purposes. As a starting point level descriptors of the previous upper secondary school curriculum (National Core Curriculum 2003) were used. In the previous curriculum speaking is described in a more detailed and analytic way which suits better for automated assessment purposes. The 2003 level descriptors are a Finnish application of the Common European Framework of Reference. More information: Kautonen, M. & von Zansen, A. (2020).

description: A simple and sensitive method has been developed for the determination of chloroacetic acids and acetic acid in water using capillary zone electrophoresis under modified electroosmotic flow with indirect UV detection. Potassium hydrogen phthalate at pH 5.40 was used as background electrolyte (BGE), and hexadecyltrimethylammonium bromide was used as electroosmotic flow modifier. Field-amplified sample injection (FASI) method was used to enhance the sensitivity. Results showed that the limit of detection for these analytes was enhanced more than 15-fold and the repeatabilities were good with relative standard deviations (RSDs %) of migration time and corrected peak areas being below 0.33%, 4.45% (intra-day) and 0.87%, 9.67% (inter-day), respectively. An off-line liquid–liquid extraction (LLE) process with methyl tert-butyl ether was carried out to detect these compounds in water samples. The dissociation constants of acetic acid and monochloroacetic acid (MCA) were determined with two methods and the results obtained were consistent with the reference values.

description: Here we report on synthesis of new organic-inorganic materials based on products of interaction between sodium aminoprusside and polymer ligands. Fourier transform infrared (FT-IR) and UV-visible spectroscopy and thermogravimetry were used to investigate the structure and stability of the complexes. It was found that ion and ligand exchange were the main reactions of the interaction of sodium aminoprusside with water-soluble polymer salts. All other composites in the Co(II) form were characterized in terms of sorption capacities and distribution coefficients (Kd) for cesium ions. The highest values of distribution coefficients were obtained for polyampholyte chitosan derivatives.

description: The Olympic Mudminnow Novumbra hubbsi is a highly endemic freshwater fish found only in Washington State, where their distribution is limited to low-elevation wetland habitats. The distributional extent of the Olympic Mudminnow is well established, but local and watershed environmental features associated with their presence or absence within the range are poorly understood, making it difficult to determine habitat needs versus availability. We surveyed 22 sites in 2 years along the Chehalis River with the objective of modeling environmental characteristics associated with occupancy by Olympic Mudminnows, while also accounting for incomplete detection. Occupancy and detection probabilities were highly similar between years, and occupancy that incorporated detection probabilities was 47% higher than naive estimates in a given year. Modeling with environmental covariates supported the importance of low temperatures for predicting the occurrence of Olympic Mudminnows at sites, and detection within sites was associated most strongly with shallow depths and low dissolved oxygen. These results are consistent with prior research indicating the preferential use of groundwater springs by Olympic Mudminnows, particularly in warmer summer months. Our research expands the existing knowledge of Olympic Mudminnow distributions by documenting main-stem-oriented populations at varying levels of abundance and suggesting habitat features that may increase occupancy and detection probabilities. The sampling and modeling approach we describe also informs development of standardized survey protocols for Olympic Mudminnows, helping to optimize resources for monitoring occupancy and abundance across their limited range.

description: A re-examination of Scrophularia canina L. confirmed the presence of iridoid glucosides considered as chemotaxonomic markers for the Scrophulariaceae family, like aucubin, harpagide and 8-O-acetylharpagide, besides the further presence of 8-epiloganic acid, which is, indeed, considered the biogenetic precursor of iridoids normally found in Scrophulariaceae, and was recognised here for the first time in the studied species. Also verbascoside and (E)-phytol were evidenced for the first time in S. canina. The former compound is an almost ubiquitous glycosidic phenyl-ethanoid, which attains systematic importance when in co-occurrence with iridoids, and its taxonomical implications were discussed. The latter compound, even though it is omnipresent, is interestingly endowed with several biological activities, which may give an additional reason for the traditional uses of this plant.

description: The Schiff base compound (E)-4-[(2-hydroxybenzylidene)amino]phenyl benzenesulphonate has been synthesised from the reaction of 4-aminophenyl benzenesulphonate and salicylaldehyde, and characterised by spectroscopic and single-crystal X-ray diffraction techniques. Quantum chemical calculations employing density functional theory method with the 6-311++G(d,p) basis set were performed to study the molecular, spectroscopic and enol-imine/keto-amine tautomerisation mechanism of the title compound. An acceptable correlation between experimental and theoretical findings is obtained. Enol-imine/keto-amine tautomerisation mechanism was investigated in the gas phase and in solution phase using the polarisable continuum model approximation. The energetic and thermodynamic parameters of the enol-imine → keto-amine transfer process show that the single proton exchange is unfavoured in all cases. Contrarily, the reverse reaction seems to be feasible with a very low barrier height and is supported by negative values in enthalpy and free energy changes for all cases.

description: One of the characteristic aspects of odour sensing in humans is the activation of olfactory receptors in a slightly different manner to different enantiomers. Here, we focused on whether plants showed enantiomer-specific responses similar to that in humans. We exposed Arabidopsis seedlings to methanol (control) and (+)- or (−)-borneol, and found that only (+)-borneol reduced the root length. Furthermore, the root-tip width was more increased upon (+)-borneol exposure than upon (−)-borneol exposure. In addition, root-hair formation was observed near the root tip in response to (+)-borneol. Auxin signalling was strongly reduced in the root tip following exposure to (+)-borneol, but was detected following exposure to (−)-borneol and methanol. Similarly, in the root tip, the activity of Cyclin B1:1 was detected on exposure to (−)-borneol and methanol, but not on exposure to (+)-borneol, indicating that (+)-borneol inhibits the meristematic activity in the root. These results partially explain (+)-borneol-specific reduction in the root length of Arabidopsis. Our results indicate the presence of a sensing system specific for (+)-borneol in Arabidopsis.

description: The π-stacking effects of substituted benzenes on the N-glycosidic bond strength of 3-methyl-2'-deoxyadenosine (3-MDA) were studied by quantum mechanical calculations. Although all substituents enhance the stacking interactions, enhancement is higher for the electron-donating (ED) substituents. When the overall binding energy is separated into the π···π (ΔEπ···π) and backbone···π (ΔEbb···π) contributions, the ED and electron-withdrawing (EW) substituents increase those contributions, respectively. Both the ED and EW substituents decrease the distance between the centres of stacked rings, while the EW ones increase the N-glycosidic bond length. The electron charge density calculated at the C--N bond critical point (ρC–N) is in linear correlation with the backbone···π interaction, not with the π···π interaction. This study also shows that the charge transfer from X-Ben to 3-MDA is in linear correlation with the ΔEπ···π and the change in the charge on the sugar ring is in better accordance with the backbone···π interaction. The N7 proton affinity (PAN7), with a key role in the depurination process, is highly affected by the π···π interactions. Thus, both interactions must be considered because of the balance between the backbone···π and π···π contributions in these biomolecular systems.

description: Simultaneous planning of project scheduling and material procurement can improve the project execution costs. Hence, the issue has been addressed here by a mixed-integer programming model. The proposed model facilitates the procurement decisions by accounting for a number of suppliers offering a distinctive discount formula from which to purchase the required materials. It is aimed at developing schedules with the best net present value regarding the obtained benefit and costs of the project execution. A genetic algorithm is applied to deal with the problem, in addition to a modified version equipped with a variable neighbourhood search. The underlying factors of the solution methods are calibrated by the Taguchi method to obtain robust solutions. The performance of the aforementioned methods is compared for different problem sizes, in which the utilized local search proved efficient. Finally, a sensitivity analysis is carried out to check the effect of inflation on the objective function value.

description: We present an overview of Oruga: a tool built on the foundations set by Representational Systems Theory (RST). Oruga allows us to (1) encode the structure of diverse representations, (2) reason about representations, and (3) transform representations across representational systems. Given the variety of form and purpose of existing representations, it is essential that computational systems are able to transform and select between them to best suit the task at hand, considering that the best choice may be a diagram, a table, a sentence, or something else. Oruga’s ability to transform and reason about representations allows us to do the required analysis and assess the benefits of one over the other, from both formal and cognitive perspectives.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: This work aimed to optimize the extraction of an extracellular protease produced by the cold-adapted yeast Rhodotorula mucilaginosa L7 using aqueous two-phase systems (ATPS) comprising polyethylene glycol (PEG) and sodium citrate or sodium tartrate. First, the biocompatibility of the phase forming agents was assessed. The results obtained with PEG-2000, PEG-4000, and PEG-6000 demonstrated that even at large PEG concentrations (32 wt%) the protease maintains its activity after 3 h of reaction, whereas an increase in salt concentration provokes a gradual decrease in protease stability. Subsequently, the partitioning of the protease in both types of ATPS was assessed, evaluating the effect of temperature, molecular weight, and concentration of PEG on protease purification, using two 23-full factorial designs. The best partitioning conditions were obtained in PEG-6000/sodium tartrate-based ATPS, at 30ºC (with a yield of 81.09 ± 0.66% and a purification factor of 2.51 ± 0.03). Thus, considering the biodegradable characteristics of the system, the PEG/sodium tartrate ATPS is a viable and economic low-resolution step in protease purification, with a strong potential for future industrial application.

description: High-performance processors have long used instruction-level parallelism (ILP) to achieve performance, but in the past decade processor vendors have dramatically increased their reliance upon this technique. We therefore take another look at the theoretical limits of ILP, in order to evaluate challenges and opportunities for processor architectures. Using the dynamic dependency graph of general-purpose workloads, we find that the upper bound on ILP is surprisingly close to the IPC capabilities of current state-of-the-art cores. Our results suggest that there may be as little as a decade of further scaling on current trends before hardware capabilities exceed the ILP bound.

description: Cambodia’s Lower Sesan II Dam has a rocky history. The ADB deemed it “undesirable” in 1999. Vietnam dropped out in 2007. It was disparaged as an environmental disaster and an abuse of human rights internationally. And yet the dam was officially completed in 2018 to much fanfare with help from China’s Belt and Road Initiative (BRI). This case study asks: what factors made Cambodia decide to build this dam, despite global experts advising otherwise? Who was this dam built for, and what trade-offs were Cambodian policy makers willing to make for them? What are Cambodia's plans for mitigating the societal and environmental impact of the dam? Why was China willing to join in when no one else would? These questions are important for extrapolating this dam to the likely construction of future large infrastructure projects in the context of development in the Mekong Region and increasing scale of the BRI.
Choosing to Forget: A Discussion on Singapore's National Identity with respect to Demolished Buildings

description: Buildings are not only physical structures, but they also store memories that allow for intergenerational storytelling. The Old National Library, the Old Kallang Stadium, and Dakota Crescent are more than popular destinations for Singaporeans. Each of these places contains many unrecorded tales of the families and individuals who have come and gone, and these stories weave together to form a collective narrative beyond the British-Japanese-Malaysian-Singapore textbook storyline. A study of the demolished national buildings in Singapore would outline parts of our shared heritage and question the justification of placing an oversized and oversimplified importance on economic factors. In this case study, we adopt the approach of a panel discussion between three learned individuals to consider some of the perspectives around the issue of building preservation and how that shapes national identity. Through the study of three notable examples, the “panellists” will illustrate the various viewpoints and demonstrate the multi-faceted and highly political nature of heritage, to show that it is not always a simple decision with regard to whether a place is demolished, conserved or preserved. This case study will examine the roles that different stakeholders, namely government organisations and civil society, play in the decision-making process.

description: As states have become more crowded and complex, and demands on transportation have grown, an issue that states continue to grapple is deciding on the types of public and private roles in the ownership, funding, planning, managing, and operating arrangements of public transport. In Singapore, this struggle is best observed in the management of the Mass Rapid Transit (MRT) system. Since its inception, the MRT system has changed from being completely state owned and operated, to being managed and operated by a government-linked company (SMRT), then being managed and operated by two listed companies (SMRT and SBS Transit), and to the current public-private hybrid model where operations are privatised under SMRT or SBS Transit, but operating assets are state-owned. This case study seeks to explore the effect of privatisation and listing on the performance of the MRT, focusing on the period between 2011 to 2017 when SMRT struggled with multiple high-profile rail disruptions and widespread public criticism.
A Triple Bottom Line: Apple's Investments in Indonesia

description: Foreign Direct Investment (FDI) can lead to productivity gains and economic development in developing countries. But creating a regulatory framework that both attracts foreign corporates and makes the most of their investments for domestic economic development is challenging. In 2015, Apple wanted to invest in the Indonesian market, but wasn’t willing to meet existing regulatory requirements. After two years of talks, Indonesia introduced a new and novel approach to local content requirements that has achieved a triple bottom line –benefits for the country and the company, while also seeing Apple act consistently with its most lofty corporate values. Under Indonesia’s new regulation, rather than manufacturing locally, Apple invested in three training academies across the archipelago to gain access to local consumer markets. These training Academies have developed Indonesian human capital and had spill-over benefits for the local education and technology sectors. While Apple pursued the academies to gain market access, it also benefits from the development of local apps that boost the attractiveness of the iPhone to Indonesian consumers. This case study will explore the use of local content requirements in Indonesia, how Apple has complied with Indonesian regulations, and the benefits of Apple’s training academies. The case study will consider the scalability and replicability of Indonesia’s approach.

description: The lowest lying states of LiH have been widely used to develop and calibrate many different methods in quantum mechanics. In this paper, we show that the electron-transfer processes occurring in these two states are a difficult test for chemical bonding descriptors and can be used to assess new bonding descriptors on its ability to recognise the harpoon mechanism. To this aim, we study the bond formation mechanism in a series of diatomic molecules. In all studied electron reorganisation mechanisms, the maximal electron-transfer variation point along the bond formation path occurs when about half electron has been transferred from one atom to another. If the process takes place through a harpoon mechanism, this point of the reaction path coincides with the avoided crossing. The electron sharing indices and one-dimensional plots of the electron localisation function and the Laplacian of the electron density along the molecular axis can be used to monitor the bond formation in diatomics and provide a distinction between the harpoon mechanism and a regular electron reorganisation process.
Improving the Welfare of Platform Workers in Singapore

description: Employment legislation typically protects the rights and welfare of workers who have an employment contract with an employer. Societal expectations around the employee-employer relationship also create further safeguards for employee rights. However, the rise of the gig economy has raised concerns about welfare of workers not thus protected. Workers for private hire vehicle platforms (like Grab and Gojek) and food delivery companies (like Foodpanda and Deliveroo) are typically not considered employees and are therefore not provided by such legislation and expectations. With the growing prevalence of such platform work, how should policy gaps relating to platform workers’ welfare be addressed by governments, organised labour and business? This case study leads students to consider the situation of private hire drivers and food delivery couriers in Singapore, analyse measures taken in other countries, and, in light of what has actually been done up to December 2019, suggest possible further steps.

description: This work aimed to optimize the extraction of an extracellular protease produced by the cold-adapted yeast Rhodotorula mucilaginosa L7 using aqueous two-phase systems (ATPS) comprising polyethylene glycol (PEG) and sodium citrate or sodium tartrate. First, the biocompatibility of the phase forming agents was assessed. The results obtained with PEG-2000, PEG-4000, and PEG-6000 demonstrated that even at large PEG concentrations (32 wt%) the protease maintains its activity after 3 h of reaction, whereas an increase in salt concentration provokes a gradual decrease in protease stability. Subsequently, the partitioning of the protease in both types of ATPS was assessed, evaluating the effect of temperature, molecular weight, and concentration of PEG on protease purification, using two 23-full factorial designs. The best partitioning conditions were obtained in PEG-6000/sodium tartrate-based ATPS, at 30ºC (with a yield of 81.09 ± 0.66% and a purification factor of 2.51 ± 0.03). Thus, considering the biodegradable characteristics of the system, the PEG/sodium tartrate ATPS is a viable and economic low-resolution step in protease purification, with a strong potential for future industrial application.

description: In 2006, the Myanmar Ministry of Electric Power and the China Power Investment Corporation signed a memorandum of understanding to construct the Myitsone dam in Myanmar. The construction site for the dam was to be in Kachin state at the source of Ayarwaddy river, which has supported the local population, and wider population downstream with a means of livelihood, culture, identity and sustece. Despite strong resistance, pre-construction works went ahead in 2009 and over 12,000 ethnic Kachin villagers were forcefully displaced. Political reforms in 2010, which led to the election of a new quasi-civilian led government, changed the landscape of political decision-making. Ceding to intense public pressures, the new government suspended the Myitsone dam’s construction in September 2011. However the project has led to impoverishment outcomes for the forcefully displaced who continued to live with unfavourable outcomes despite the dam’s suspension.
