Project-based learning oriented STEAM: the case of micro–bit paper-cutting lamp
Authors: Lu Shih-Yun , Lo Chih-Cheng , Syu Jia-Yu 
Published: December 2021

AbstractThe main purpose of the living technology curriculum is to cultivate students' interest in learning science and technology, and further to utilize their experience of learning instructions and develop their ability to integrate interdisciplinary knowledge and skills. In recent years, as countries have begun to emphasize the concept of interdisciplinary integration in the school education, STEM (Science, Technology, Engineering, and Mathematics, STEM) focuses on cultivating interdisciplinary talents. With this, STEAM highlights the role of ART because other dimensions of STEM are expected to be effectively integrated through the cultivation of aesthetics; the purpose of this study is to design a STEAM curriculum for elementary school children and to explore the impact of STEAM education on the creativity. The content of this course is based on the PBL (Project-Based Learning) with the teaching activities combining with “Chinese Paper-cutting” and “BBC micro: bit”. The teaching process is used the strategy of creative thinking instruction. The research method adopts a one-group pretest–posttest design based on a purposive sampling of 21 students from one class in an elementary school. The research tools included the records of learning feedback and the creativity assessment. The empirical findings show that the project-based learning incorporating STEAM activity has a positive significant influence on students’ development of creative recognition. Since the empirical results are constricted by the short-term STEAM course, the STEAM course with the art-oriented still benefits the STEAM education and Learning effectiveness of elementary school students. The implication of interdisciplinary interactive Lamp of Paper Carving with Micro:Bit is expected to contribute to further development of STEAM course. Since the curriculum is only last for few weeks, it is too short to affect the emotional facet of creativity. Future researches are suggested to extend the teaching period and evaluate the long-term influence of PBL STEAM on students' learning attitude.

dimensional Kardar–Parisi–Zhang (KPZ) equation on a finite spatial interval. In particular, we extend the results for small coupling strengths obtained previously to large values of the coupling parameter. It will be shown that, due to the scaling behavior of the KPZ equation, the thermodynamic uncertainty relation (TUR) product displays two distinct regimes which are separated by a critical value of an effective coupling parameter. The asymptotic behavior below and above the critical threshold is explored analytically. For small coupling, we determine this product perturbatively including the fourth order; for strong coupling we employ a dynamical renormalization group approach. Whereas the TUR product approaches a value of 5 in the weak coupling limit, it asymptotically displays a linear increase with the coupling parameter for strong couplings. The analytical results are then compared to direct numerical simulations of the KPZ equation showing convincing agreement.

Published: December 2021

Abstract
Purpose
Thermal rheology (TR) fluid, which comprises polyethylene (PE) particles, their dispersant, and solvent, is a material that increases in viscosity to various degrees depending on the type and ratio of these constituents when its temperature rises. The viscosity of type 1 (TRF-1) increases more than that of type 2 (TRF-2) near rabbit body temperature. This preliminary animal study aimed to determine the basic characteristics and embolic effect of TR fluid by comparing TRF-1 and TRF-2.

Materials and methods
Twenty-four Japanese white rabbits underwent unilateral renal artery embolization using TRF-1 or TRF-2 and follow-up angiography at 7 or 28 days (4 subgroups, n = 6 each). Subsequently, the rabbits were euthanized, and the embolized kidneys were removed for pathological examination. The primary and final embolization rates were defined as the ratio of renal artery area not visible immediately after embolization and follow-up angiography, respectively, to visualized renal artery area before embolization. The final embolization rate and maximum vessel diameter filled with PE particles were compared between materials. Moreover, the embolic effect was determined to be persistent when a two-sided 95% confidence interval (CI) for the difference in means between the embolization rates was < 5%.

Results
The final embolization rate was significantly higher for the TRF-1 than for the TRF-2 at both 7 (mean 80.7% [SD 18.7] vs. 28.4% [19.9], p = 0.001) and 28 days (94.0% [3.5] vs. 37.8% [15.5], p < 0.001). The maximum occluded vessel diameter was significantly larger for TRF-1 than for TRF-2 (870 µm [417] vs. 270 µm [163], p < 0.001). The embolic effect of TRF-1 was persistent until 28 days (difference between rates − 3.3 [95% CI − 10.0–3.4]).

Conclusion
The embolic effect of TRF-1 was more persistent than that of TRF-2, and the persistency depended on the type and ratio of TR fluid constituents.

Published: December 2021

AbstractThis paper describes a review of the state-of-the-art research carried on the fresh and hardened properties of Alkali Activated Binders and Concretes. Though, many research have been carried out in the recent times on alkali activated binders, few key parameters still remain unattended, that restricts the commercial application of AAMs to the general construction activities. Fresh properties, mechanical strength and durability performance of Alkali activated concrete with various Alumino silicates as base materials is mentioned. An essential parameter of Alkali activated concrete is the concentration of alkaline solution on which various properties like mechanical strength, setting time and durability depends. Influence of wide range of concentrations from 6 to 16 M on these properties are studied and reported in this paper. This paper mainly concentrates on properties of readily available base materials such as Fly ash and Slag and the means to improve their performance through the use of various industrial and agro-based byproducts as additives. Problems pertaining to practical applicability of AAMs to general construction activities are also highlighted.
Enhancing septoria leaf blotch forecasts in winter wheat II: model architecture and validation results

AbstractIn precision agriculture, pesticides and other inputs shall be used precisely when (and where) they are needed. European Directive 2009/128/EC calls for respecting the principles of integrated pest management (IPM) in the member states. To clarify the question, when, for instance, fungicide use is needed, the well-established economic principle of IPM may be used. This principle says that pests shall be controlled when the costs of control correspond with the damage the pests will cause. Disease levels corresponding with the costs of control are referred to as control thresholds in IPM. Several models have been developed in plant pathology to predict when epidemics will occur, but hardly any of these models predicts a control threshold directly limiting their usefulness for answering the question when pest control is needed according to the principles of IPM. Previously, we quantified the temporal distance between critical rainfall periods and the breaking of the control threshold of Zymoseptoria tritici on winter wheat as being affected by temperature, based on data from 52 field experiments carried out in Luxembourg from 2005 to 2016. This knowledge was used to construct the ShIFT (SeptorIa ForecasT, https://shift.list.lu/) model, which has been validated using external data recorded between 2017 and 2019. Within the efficacy period of a systemic fungicide, the model allowed correct predictions in 84.6% of the cases, while 15.4% of the cases were predicted falsely. The average deviation between the observed and predicted dates of epidemic outbreaks was 0.62 ± 2.4 days with a maximum deviation of 19 days. The observed and predicted dates were closely correlated (r = 0.92, P < 0.0001). Apart from outliers, the forecast model tested here was reliable within the period of efficacy of current commercial fungicides.
Multilayered Oversight: Electoral Administration in Indonesia
Authors: Butt Simon , Siregar Fritz 
Published: December 2021

AbstractElectoral administration in Indonesia is complex. The Electoral Commission (Komisi Pemilihan Umum) is responsible for planning and running five-yearly elections for one national and two regional legislatures, and one additional national regional representative body, as well as direct presidential, gubernatorial, mayoral and regent elections. Because candidates and parties often have significant financial stakes in their outcome, these elections are hotly contested and the results quite commonly disputed, including in Indonesia's Constitutional Court (Mahkamah Konstitusi). Electoral contestants often point to mistakes in administration and vote counting, which appear to be natural consequences of the great logistical challenges these elections present. For example, on 17 April, 2019, well over 150 million citizens attended one of over 800,000 polling stations to vote for candidates to fill 19,817 legislative seats in national and subnational parliaments. Many of these elections are said to be marred by attempts by candidates and their parties to gain illegal advantage, whether through misuse of incumbency or vote buying. There is also said to be much potential for corruption amongst electoral administrators themselves in registering candidates, verifying parties, procuring equipment for polling stations, and counting and tallying votes on election day. Given the potential of mistakes and illegality to jeopardise the legitimacy of election results, lawmakers in Indonesia have created multi-layered oversight mechanisms to oversee the planning and running of the elections by the Electoral Commission, as well as to oversee the Election Supervisory Board (Bawaslu, Badan Pengawas Pemilihan Umum) itself, which is charged with supervising that Commission. This article examines the work and performance of these institutions, and the Electoral Administration Honour Council (DKPP, or Dewan Kehormatan Penyelenggara Pemilu), which hears allegations of breaches by the Commission and the Board.
Kant and Stoic Affections
Authors: Merritt Melissa 
Published: December 2021

AbstractI examine the significance of the Stoic theory ofpathē(and related topics) for Kant’s moral psychology, arguing against the received view that systematic differences block the possibility of Kant’s drawing anything more than rhetoric from his Stoic sources. More particularly, I take on the chronically underexamined assumption that Kant is committed to a psychological dualism in the tradition of Plato and Aristotle, positing distinct rational and nonrational elements of human mentality. By contrast, Stoics take the mentality of an adult human being to be rational through and through, while recognising that this rationality is not normally in a state of health or excellence. I show how Kant’s account of affections—chiefly the “affects” and “passions” that he identifies as targets of a duty of apathy—draws substantive lessons from his Stoic sources, and how he accepts on his own terms the monistic principles of Stoic moral psychology.
Dimensional research on organization structure: meta-analysis and conceptual redirection
Authors: Wagner John A. 
Published: December 2021

AbstractA previous meta-analysis of dimensional structure research published during the latter half of the 20th century revealed significant intercorrelation among structural dimensions inspired by Max Weber's bureaucratic ideal type, providing support for continued research on dimensional structures and for the bureaucratic structural model that served as its theoretical foundation. A new meta-analysis reported in this article, motivated by questions regarding the continued applicability of bureaucratic dimensional models in the later era of new organization forms, indicates that many of the interrelationships among five structural dimensions (formalization, standardization, specialization, vertical differentiation, and decentralization) have weakened since the time of the earlier meta-analysis. The results of this study, conducted using a sample of 346 correlations from a collection of 155 published articles, are interpreted as failing to provide consistent evidence supporting a central tenet of the bureaucratic structural model, therefore, as indicating that dimensional structural research now lacks a viable theoretical foundation.
Commissions of inquiry and pathways to accountability in Plateau State, Nigeria
Authors: Oosterom Marjoke , Sha Dung Pam , Dowd Caitriona 
Published: December 2021

ABSTRACTFor decades, Plateau State in Nigeria's Middle Belt has witnessed repeated ethnoreligious violence. Over this period, both state and federal governments have established formal Commissions of Inquiry (COIs) in response to unrest, tasked with investigating violence, identifying perpetrators, and – ultimately – strengthening accountability. While commissions’ mandates and specific outcomes varied, there is general consensus that inquiries have been largely ineffective at securing justice or establishing accountability for violence. This study seeks to understand the expectations placed on, and role of, COIs in Plateau State as pathways to formal accountability in a context of recurring violence. We argue that COIs are embedded in the complex, multilevel networks and politics of state and non-state institutions. Civil society, in turn, has diverse expectations and demands, and articulates these in fragmented ways. As a result, COIs served primarily as another avenue for interest-based negotiations.
Incerta Pro Certis: An Interpretation of Sallust Bellum Catilinae 48.4-49.4
Authors: Batstone William W. 
Published: December 2021

Sallust's style is provocative and tendentious, but does his admitted moral tendentiousness carry over into a political or partisan tendentiousness? For centuries we have heard of Sallust the partisan, Sallust the propagandist, Sallustian bias. The history of this perceived bias began at least in the age of Augustus when the anonymous writer of the Invectio in Ciceronem set stylus to wax and began his fraud. Less than a century later (before 96 A.D.) Quintilian regarded the work as genuine Sallust (I.O. 4.1.68; 9.3.89). The deception had worked; and both the fraud itself and Quintilian's acquiescence indicate a perceived anti-Gceronian bias to Sallust's writing.In the modern period, the history of perceived bias, already resisted by Voss, came to its climax in 1897 with an article by E. Schwartz which argued for a systematic and extreme anti-Ciceronian and pro-Caesarian bias and purpose to the Bellum Catilinae. The charges seemed to Schwartz necessary to explain (1) Sallust's chronology, (2) the significantly small role played by Cicero in Sallust's monograph, and (3) the report of certain rumours which implicated Cicero and Crassus and the denial of rumours which implicated Caesar. A systematic review of the arguments, however, gradually undermined or called into question the validity of most of Schwartz's points. By 1964 Syme could say that the main charges against Sallust had collapsed upon inspection. And they had; all but one.
The Simile of the Fractured Pipe in Ovid's Metamorphoses 4

Published: December 2021

When Pyramus, the romantic hero of Ovid's tale of ‘Pyramus and Thisbe’ (Met. 4.55-166), mistakenly assumes his beloved Thisbe is dead and thus kills himself beneath a mulberry tree with a sword, Ovid punctures this moment of tragic pathos by a simile comparing the blood spurting from Pyramus' wound to water gushing from a broken pipe (4.119-24):demisit in ilia ferrum,nec mora, ferventi moriens e vulnere traxitet iacuit resupinus humo: cruor emicat alte,non aliter, quam cum vitiato fistula plumboscinditur et tenui stridente foramine longaseiaculatur aquas atque ictibus aera rumpit.he plunged the sword into his groin, and straightaway, dying, he drew it from the seething woundand lay back on the ground: the blood spurts highexactly as when a pipe, split open from corrupted lead,ejaculates a long stream of water through the tinyhissing aperture and bursts upon the air with its blows.
Forced alignment for Nordic languages: Rapidly constructing a high-quality prototype
Authors: Young Nathan J. , McGarrah Michael 
Published: December 2021

AbstractWe propose a rapid adaptation of FAVE-Align to the Nordic languages, and we offer our own adaptation to Swedish as a template. This study is motivated by the fact that researchers of lesser-studied languages often neither have sufficient speech material nor sufficient time to train a forced aligner. Faced with a similar problem, we made a limited number of surface changes to FAVE-Align so that it – along with its original hidden Markov models for English – could be used on Stockholm Swedish. We tested the performance of this prototype on the three main sociolects of Stockholm Swedish and found that read-aloud alignments met all of the minimal benchmarks set by the literature. Spontaneous-speech alignments met three of the four minimal benchmarks. We conclude that an adaptation such as ours would especially suit laboratory experiments in Nordic phonetics that rely on elicited speech.

Published: December 2021

SummaryThe purpose of this study was to investigate the effect of RFRP-3 synchronized with photoperiods on regulating the seasonal reproduction of striped hamsters. The striped hamsters were raised separately under long-day (LD; 16 h light/8 h dark), medium-day (MD; 12 h light/12 h dark) or short-day (SD; 8 h light/16 h dark) conditions for 8 weeks. RFRP-3 and gonadotropin-releasing hormone (GnRH) mRNA levels in the hypothalamus, testis or ovaries in three groups were detected using reverse transcription polymerase chain reaction (RT-PCR). Melatonin (MLT), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) concentrations in serum were detected using enzyme-linked immunosorbent assay (ELISA). The correlation between RFRP-3 and GnRH mRNA and FSH and LH concentrations was also analyzed. MLT negatively regulated the expression of RFRP-3. Significant differences for RFRP-3 mRNA existed in the three groups, which positively correlated with the GnRH and the FSH and LH concentrations. RFRP-3 mRNA levels in the hypothalamus were significantly higher than those in ovaries or testis. RFRP-3 levels in the hypothalamus were significantly lower in female than in male under SD conditions, while those in ovaries were significantly higher than those in testes under LD conditions. MLT decreased RFRP neuron activity, and RFRP-3 regulated the reproduction of striped hamsters.
Dual-band all textile antenna with AMC for heartbeat monitor and pacemaker control applications
Authors: Kareem Farah R. , El Atrash Mohamed , Ibrahim Ahmed A. , Abdalla Mahmoud A. 
Published: December 2021

AbstractAll textile integrated dual-band monopole antenna with an artificial magnetic conductor (AMC) is proposed. The proposed design operates at 2.4 and 5.8 GHz for wearable medical applications to monitor the heartbeat. A flexible and low-profile E- shaped CPW dual-band textile antenna is integrated with a 4 × 4 dual-band textile AMC reflector to enhance the gain and specific absorption rate (SAR). The SAR is reduced by nearly 95% at both 1 and 10 g. The design was measured on the body with a 2 mm separation. The simulated and measured results appear in high agreement in the case of with and without AMC array integration. The measurement was performed in the indoor environment and in an anechoic chamber to validate the design based on reflection coefficient and radiation pattern measurements.

AbstractFlower and fruit development are two key steps for plant reproduction. The ABCE model for flower development has been well established in model plant species; however, the functions of ABCE genes in fruit crops are less understood. In this work, we identified an EMS mutant named R27 in woodland strawberry (Fragaria vesca), showing the conversion of petals, stamens, and carpels to sepaloid organs in a semidominant inheritance fashion. Mapping by sequencing revealed that the class E gene homolog FveSEP3 (FvH4_4g23530) possessed the causative mutation in R27 due to a G to E amino acid change in the conserved MADS domain. Additional fvesep3CR mutants generated by CRISPR/Cas9 displayed similar phenotypes to fvesep3-R27. Overexpressing wild-type or mutated FveSEP3 in Arabidopsis suggested that the mutation in R27 might cause a dominant-negative effect. Further analyses indicated that FveSEP3 physically interacted with each of the ABCE proteins in strawberry. Moreover, both R27 and fvesep3CR mutants exhibited parthenocarpic fruit growth and delayed fruit ripening. Transcriptome analysis revealed that both common and specific differentially expressed genes were identified in young fruit at 6–7 days post anthesis (DPA) of fvesep3 and pollinated wild type when compared to unpollinated wild type, especially those in the auxin pathway, a key hormone regulating fruit set in strawberry. Together, we provided compelling evidence that FveSEP3 plays predominant E functions compared to other E gene homologs in flower development and that FveSEP3 represses fruit growth in the absence of pollination and promotes fruit ripening in strawberry.

Published: December 2021

AbstractTea plants are subjected to multiple stresses during growth, development, and postharvest processing, which affects levels of secondary metabolites in leaves and influences tea functional properties and quality. Most studies on secondary metabolism in tea have focused on gene, protein, and metabolite levels, whereas upstream regulatory mechanisms remain unclear. In this review, we exemplify DNA methylation and histone acetylation, summarize the important regulatory effects that epigenetic modifications have on plant secondary metabolism, and discuss feasible research strategies to elucidate the underlying specific epigenetic mechanisms of secondary metabolism regulation in tea. This information will help researchers investigate the epigenetic regulation of secondary metabolism in tea, providing key epigenetic data that can be used for future tea genetic breeding.
