Published: September 2022

Abstract
Background
In the transition from academic to clinical learning, the development of clinical reasoning skills and teamwork is essential, but not easily achieved by didactic teaching only. Case-based learning (CBL) was designed to stimulate discussions of genuine clinical cases and diagnoses but in our initial format (CBL’10) remained predominantly tutor-driven rather than student-directed. However, interactive teaching methods stimulate deep learning and consolidate taught material, and we therefore introduced a more collaborative CBL (cCBL), featuring a structured format with discussions in small breakout groups. This aimed to increase student participation and improve learning outcomes.

Method
A survey with open and closed questions was distributed among 149 students and 36 tutors that had participated in sessions of both CBL formats. A statistical analysis compared exam scores of topics taught via CBL’10 and cCBL.

Results
Students and tutors both evaluated the switch to cCBL positively, reporting that it increased student participation and enhanced consolidation and integration of the wider subject area. They also reported that the cCBL sessions increased constructive discussion and stimulated deep learning. Moreover, tutors found the more structured cCBL sessions easier to facilitate. Analysis of exam results showed that summative assessment scores of subjects switched to cCBL significantly increased compared to previous years, whereas scores of subjects that remained taught as CBL’10 did not change.

Conclusions
Compared to our initial, tutor-led CBL format, cCBL resulted in improved educational outcomes, leading to increased participation, confidence, discussion and higher exam scores.
Using dual evolutionary search to construct decision tree based ensemble classifier
Authors: Chen Hao , Zhang Guoxin , Pan Xiaoying , Jia Rong 
Published: September 2022

AbstractA typical ensemble learning process typically uses a forward integration mechanism to construct the ensemble classifier with a large number of base classifiers. Based on this mechanism, it is difficult to adjust the diversity among base classifiers and optimize the structure inside ensemble since the generation process has a certain amount of randomness, which makes the performance of ensemble classifiers heavily dependent on the human design decisions. To address this issue, we proposed an automatic ensemble classifier construction method based on a dual-layer evolutionary search mechanism, which includes a tree coding-based base classifier population and a binary coding-based ensemble classifier population. Through a collaborative searching process between the two populations, the proposed method can be driven by training data to update the base classifier population and optimize the ensemble classifiers globally. To verify the effectiveness of the dual evolutionary ensemble learning method (DEEL), we tested it on 22 classification tasks from 4 data repositories. The results show that the proposed method can generate a diverse decision tree population on the training data while searching and constructing ensemble classifiers from them. Compared with 9 competitor algorithms, the proposed method achieved the best performance on 17 of 22 test tasks and improved the average accuracies by 0.97–7.65% over the second place. In particular, the generated ensemble classifiers show excellent structure, which involve small number and diverse decision trees. That increases the transparency of ensembles and helps to perform interpretability analysis on them.

Published: September 2022

AbstractStimuli-responsive hydrogel is regarded as one of the most promising smart soft materials for the next-generation advanced technologies and intelligence robots, but the limited variety of stimulus has become a non-negligible issue restricting its further development. Herein, we develop a new stimulus of “touch” (i.e., spatial contact with foreign object) for smart materials and propose a flytrap-inspired touch-responsive polymeric hydrogel based on supersaturated salt solution, exhibiting multiple responsive behaviors in crystallization, heat releasing, and electric signal under touch stimulation. Furthermore, utilizing flytrap-like cascade response strategy, a soft actuator with touch-responsive actuation is fabricated by employing the touch-responsive hydrogel and the thermo-responsive hydrogel. This investigation provides a facile and versatile strategy to design touch-responsive smart materials, enabling a profound potential application in intelligence areas.
Strength and Rheology of Cemented Pastefill Using Waste Pitchstone Fines and Common Pozzolans Compared to Using Portland Cement
Authors: Yowa Gideon Gipmai , Sivakugan Nagaratnam , Tuladhar Rabin , Arpa Gabriel 
Published: September 2022

AbstractCemented pastefill is one of the most popular backfill types that use waste mill tailings to backfill and stabilise the mined-out voids in underground mines. Cement dosage in the range of 3–7% is added to the tailings to increase the strength of cemented pastefill to serve as wall support when extracting adjacent stopes. Cement is expensive and contributes significantly to the cost of backfilling even with small dosages. Moreover, the production of cement is energy intensive and contributes to the emission of carbon dioxide. Partial replacement of cement with supplementary cementitious materials can significantly reduce cost and make mine backfilling more environmentally friendly. This paper reports the findings from a laboratory test programme on the optimization of mix designs using fly ash, slag, pitchstone fines, and polycarboxylate plasticizer. Results indicated that apart from common pozzolans like fly ash and slag, the pitchstone fines attained comparable unconfined compressive strength when replacing cement by 10–20%. The findings are useful for the mining and civil industries trying to dispose the mine waste or reusing it as backfill or as construction material.
Controlling Conditional Expectations by Zero-Determinant Strategies
Authors: Ueda Masahiko 
Published: September 2022

AbstractZero-determinant strategies are memory-one strategies in repeated games which unilaterally enforce linear relations between expected payoffs of players. Recently, the concept of zero-determinant strategies was extended to the class of memory-n strategies with $$n\ge 1$$

, which enables more complicated control of payoffs by one player. However, what we can do by memory-n zero-determinant strategies is still not clear. Here, we show that memory-n zero-determinant strategies in repeated games can be used to control conditional expectations of payoffs. Equivalently, they can be used to control expected payoffs in biased ensembles, where a history of action profiles with large value of bias function is more weighted. Controlling conditional expectations of payoffs is useful for strengthening zero-determinant strategies, because players can choose conditions in such a way that only unfavorable action profiles to one player are contained in the conditions. We provide several examples of memory-n zero-determinant strategies in the repeated prisoner’s dilemma game. We also explain that a deformed version of zero-determinant strategies is easily extended to the memory-n case.
Root osmotic sensing from local perception to systemic responses
Authors: Gorgues Lucille , Li Xuelian , Maurel Christophe , Martinière Alexandre , Nacry Philippe 
Published: September 2022

AbstractPlants face a constantly changing environment, requiring fine tuning of their growth and development. Plants have therefore developed numerous mechanisms to cope with environmental stress conditions. One striking example is root response to water deficit. Upon drought (which causes osmotic stress to cells), plants can among other responses alter locally their root system architecture (hydropatterning) or orientate their root growth to optimize water uptake (hydrotropism). They can also modify their hydraulic properties, metabolism and development coordinately at the whole root and plant levels. Upstream of these developmental and physiological changes, plant roots must perceive and transduce signals for water availability. Here, we review current knowledge on plant osmotic perception and discuss how long distance signaling can play a role in signal integration, leading to the great phenotypic plasticity of roots and plant development.
Glycerol-3-phosphate acyltransferases and metabolic syndrome: recent advances and future perspectives
Authors: Huang Yinqiong , Hu Keyue , Lin Shu , Lin Xiahong 
Published: September 2022

Abstract
Triglycerol-3-phosphate acyltransferases (GPATs) are the key enzymes in the first step of the synthesis of triacylglycerol (TAG). In mammals, there are four isoforms of GPATs. GPAT1 and GPAT2 are localised in the outer mitochondrial membrane, while GPAT3 and GPAT4 are localised in the endoplasmic reticulum. Previous research has emphasised that GPAT plays a critical effect on the development of metabolic syndromes, such as liver steatosis, obesity, and insulin resistance. In this review, we will critically evaluate the regulatory effects of GPATs isoforms in metabolic syndrome. In addition, we also discuss perspectives on clinical intervention strategies for the neurometabolic disease.
Unveil the pain of endometriosis: from the perspective of the nervous system
Authors: Fan Peiya , Li Tian 
Published: September 2022

Abstract
Endometriosis is a chronic inflammatory disease with pelvic pain and uncharacteristic accompanying symptoms. Endometriosis-associated pain often persists despite treatment of the disease, thus it brings a deleterious impact on their personal lives as well as imposing a substantial economic burden on them. At present, mechanisms underlie endometriosis-associated pain including inflammatory reaction, injury, aberrant blood vessels and the morphological and functional anomaly of the peripheral and central nervous systems. The nerve endings are influenced by the physical and chemical factors surrounding the lesion, via afferent nerve to the posterior root of the spinal nerve, then to the specific cerebral cortex involved in nociception. However, our understanding of the aetiology and mechanism of this complex pain process caused by endometriosis remains incomplete. Identifying the pathogenesis of endometriosis is crucial to disease management, offering proper treatment, and helping patients to seek novel targets for the maintenance and contributors of chronic pain. The main aim of this review is to focus on every possible mechanism of pain related to endometriosis in both peripheral and central nervous systems, and to present related mechanisms of action from the interaction between peripheral lesions and nerves to the changes in transmission of pain, resulting in hyperalgesia and the corresponding alterations in cerebral cortex and brain metabolism.
CEO career horizon influence strategic novelty of a firm: A study under the boundary condition of CEO's temporal focus

Published: September 2022

AbstractThe paper examines the relationship between CEO career horizon and strategic novelty under boundary conditions of CEOs' temporal focus for firms in one of the emerging markets. Upper echelons theory predicts that CEOs' risk aggressiveness decreases with diminishing career horizons. Therefore, CEOs nearing retirement are less likely to make novel strategic investments. We assert that CEOs' career horizon influences strategic outcomes, especially risk aggressive strategic novelty outcomes contingent on the CEOs' temporal perspective, i.e., past and future temporal focus. We test the hypotheses using archival data from 285 listed firms in India. The findings support the hypotheses by showing that CEOs' carrier horizon positively influences strategic dynamism and distinctiveness, the two dimensions of strategic novelty. The results also suggest that past temporal focus enhances the negative influence of decreasing CEOs' career horizons on strategic dynamism and distinctiveness. Future temporal focus, on the contrary, diminishes the negative influence of decreasing CEOs' career horizons on strategic dynamism and distinctiveness. The findings contribute to understanding the joint role of the time static trait of CEOs, i.e., temporal focus, and time-varying trait, i.e., career horizon on strategic novelty.
On connectivity and robustness of random graphs with inhomogeneity
Authors: Shang Yilun 
Published: September 2022

AbstractThe study of threshold functions has a long history in random graph theory. It is known that the thresholds for minimum degreek,k-connectivity, as well ask-robustness coincide for a binomial random graph. In this paper we consider an inhomogeneous random graph model, which is obtained by including each possible edge independently with an individual probability. Based on an intuitive concept of neighborhood density, we show two sufficient conditions guaranteeingk-connectivity andk-robustness, respectively, which are asymptotically equivalent. Our framework sheds some light on extending uniform threshold values in homogeneous random graphs to threshold landscapes in inhomogeneous random graphs.
Proposed alcohol tax reform in the United Kingdom: Implications for wine-exporting countries
Authors: Anderson Kym , Wittwer Glyn 
Published: September 2022

AbstractA proposal to reform the United Kingdom's excise duty on alcohol is under consideration during 2022. The proposal would change the tax base from volume of product to volume of alcohol, which would see a fall in the tax on sparkling wine (by about one-fifth), a rise in the tax on fortified wines of 18% alcohol by volume (ABV) (by about one-sixth), and table wines with more (less) than 11.5% ABV would become dearer (cheaper). With taxes on most beers unchanged and taxes on spirits lowered slightly, the pattern of UK wine consumption and imports would alter considerably. This article draws on a global model of national alcoholic beverage markets to estimate the likely bilateral trade effects of this proposed reform to UK excise duties. It compares them with the trade effects of the United Kingdom's first two bilateral free trade agreements (FTAs), following the post-Brexit EU–UK Trade and Cooperation Agreement, which allows Australian and New Zealand vignerons tariff-free access to the UK wine market. Those two FTAs are estimated to cause the United Kingdom to import far more wine than is lost by the proposed changes in UK excise duties.
Does quality pay off? “Superstar” wines and the uncertain price premium across quality grades
Authors: Castriota Stefano , Corsi Stefano , Frumento Paolo , Ruggeri Giordano 
Published: September 2022

AbstractWe use data from Wine Spectator on 266,301 bottles from 12 countries sold in the United States to investigate the link between the score awarded by the guide and the price charged. The link between quality and price is positive, in line with the literature. In a deeper inspection, however, hedonic regressions show that the price premium attached to higher quality is significant only for “superstar” wines with more than 90 points (on a 50–100 scale), while prices of wines between 50 and 90 points are not statistically different from each other. Furthermore, an analysis performed through normal heteroskedastic and quantile regression models shows that the dispersion of quality-adjusted prices is described by an asymmetric U-shaped function of the score; that is, products with the lowest and highest quality have the highest residual standard deviation. Pursuing excellence is a risky strategy; the average price is significantly higher only for wines that achieve top scores, and the price premium becomes more volatile.
Evolution of Ramasetu region as a link between India and Sri Lanka during the late Pleistocene and Holocene
Authors: Dubey K.M. , Chaubey A.K. , Gaur A.S. , Joglekar M.V. 
Published: September 2022

AbstractHigh-resolution seismic data of the Ramasetu region revealed three subaerial unconformities S1, S2, and S3. S1 is the youngest subaerial unconformity, whereas S3 is the oldest. These subaerial unconformities have been determined based on the presence of channel-incision signatures. Identified buried channels originated in the Palk Strait and debouched in the Gulf of Mannar. Youngest buried channels became most active during MIS 3 (~60–29 ka) and were buried entirely at ~7.0 ka. The study suggests that the Palk Strait evolved as a large multi-centered freshwater reservoir during the last glacial period and remained a freshwater reservoir until seawater started encroaching the region at ~8.5 ka. The Ramasetu region was a potential habitat zone for foragers, with fresh and saline water ecosystems available at opposite banks. During the Microlithic and terminal Pleistocene, Homo sapiens needed to cross high-energy rivers using floaters/rafts in wet seasons of MIS 2 and 3. At the same time, they used a direct walkable land link in the extreme dry season of MIS 2. During the early to mid-Holocene, foragers required floaters/rafts or artificial structures (such as bandh/bridge) to cross shallow, low-energy estuarine patches of the Ramasetu. The Palk Strait region was not crossable without using boats/ships in the last ~7 ka except during minor sea-level falls.
Stanley Kubrick's Magic Mountain: Fiction as History in The Shining
Authors: Cocks Geoffrey 
Published: September 2022

AbstractStanley Kubrick's film The Shining (1980) can be read as a central European imaginary retelling Thomas Mann's The Magic Mountain (1924). The film constructs a dark meditation on the human condition not only through its formal and thematic focus on Mann's novel but also through the lens of works by numerous other central European artists and scholars. Consequently, The Shining presents historical comprehension as the product not only of knowledge, but of experience, memory, and artistic representation/reception. Just as The Magic Mountain addressed itself to the crisis of European civilization that had culminated in the First World War, a deep-laid historical subtext in The Shining concerns the more desperate crisis facing the West in the wake of the Second World War. At its dark center, Kubrick's horror film reflects its creator's and its era's struggle with the reality and representation of the Holocaust.
Reimagining the Public Sphere: Commensurability and Communicative Rationality under Colonialism
Authors: Biswas Sujay 
Published: September 2022

AbstractThis article discusses the Habermasian public sphere as a realm constructed through communication and offers a critique of Jürgen Habermas's concept of an intersubjectively shared lifeworld among the participants as a fundamental prerequisite for communicative rationality in the discursive field. The article contends that the emergence of communicative rationality in the public sphere is unlikely to be facilitated by a singular and unitary modern public whose participants have commensurable languages and worlds. This argument is elaborated through an analysis of a public debate that occurred on August 10, 1888, between the Mahajan (headman) of the Modh Baniya caste council and Mohandas K. Gandhi, a Modh Baniya himself. Even though the discussion involved two people with an intersubjectively shared lifeworld, who were engaged in the deliberation as equals, the dialogue broke down, deepening divides. This article argues that the need to protect the spiritual domain from the polluting touch of the material domain led to the breakdown of communicative rationality.
Participatory Democracy, Democratic Education, and Women
Authors: Lupien Pascal 
Published: September 2022

AbstractParticipatory democrats argue that citizen engagement at the local level serves an important educational function. Through involvement in participatory mechanisms, citizens develop various skills, become better informed, and cultivate a greater sense of political efficacy. There has been considerable debate in the academic literature over the extent to which participation can produce these benefits, but deliberative and participatory theoretical approaches have been criticised for neglecting power dynamics within participatory mechanisms themselves, and for overlooking structural inequalities between women and men. Numerous critics have charged that participatory mechanisms tend to mask, but not eliminate, gender inequalities, particularly in societies where these remain firmly entrenched. While the theory on the educational function of participatory democracy is well developed, there remains a lack of empirical work on the impact of participation on women in Latin America, a region that has been at the forefront of democratic innovation. Based on extensive fieldwork in Venezuela, Ecuador and Chile, this article identifies the types of skills that women gain through participation, and questions the extent to which these reproduce traditional gender roles.
Cambio de hábito: Trayectorias de religiosas durante la última dictadura militar Argentina
Authors: Catoggio María Soledad 
Published: September 2022

ResumenEl artículo tiene como objeto abordar la singularidad de las trayectorias de mujeres consagradas durante la última dictadura militar en la Argentina. La hipótesis del trabajo es que su doble condición de mujeres y consagradas las situó coyunturalmente en una posición de ventajas comparativas para hacer frente a la represión estatal. Para llevarlo a cabo reconstruimos un derrotero típico a partir de una selección intencionada de historias de vida y entrevistas a profundidad realizadas a religiosas de diversas congregaciones para luego analizar comparativamente el repertorio de estrategias agenciado por las religiosas para enfrentar la represión estatal en distintos contextos, desplegado a partir de dicho derrotero típico. Para concluir exponemos cuatro tipos de estrategias, que combinan visibilidad y agencia, y que resultan eficaces para sortear exitosamente situaciones de represión estatal en las que estas mujeres se ven expuestas.
Indigenous Language Usage and Maintenance Patterns among Indigenous People in the Era of Neoliberal Multiculturalism in Mexico and Guatemala
Authors: Yoshioka Hirotoshi 
Published: September 2022

AbstractIn both Mexico and Guatemala, indigenous languages are at risk of extinction. Because languages influence people's ways of thinking and help them identify with particular ethnic groups, indigenous language loss can result in severe problems that extend well beyond the demise of these languages. Although current multicultural reforms offer indigenous people unprecedented opportunities, these seemingly positive changes may actually threaten indigenous languages and cultures. Using the latest demographic census data, I present how socioeconomic, demographic, and community factors negatively correlate with indigenous language usage. I contend that indigenous language maintenance will become more difficult because neoliberal multiculturalism endorses indigenous cultural rights without putting forth other necessary changes. Establishing effective language preservation strategies requires us to recognize dangers hidden in the current multicultural agenda, to rigorously ask how we can destigmatize negative images attached to indigenous cultures, and to combat centuries-long oppression and discrimination against indigenous groups.
