A qualitative evaluation of a video gambling campaign among young Australians
Authors: Younes Natalie , Hronis Anastasia 
Published: August 2023

AbstractGambling is an emerging public health issue within Australia, which can lead to various adverse impacts on individuals and society. Online gambling is becoming increasingly popular and is considered a high-risk environment where problem gambling is likely to occur. This rising prevalence emphasises the need for prevention and responsible gambling initiatives in Australia. C’Mon Australia Don’t Let the Game Play Ya! is a recently developed responsible gambling video campaign. The campaign focuses on online gambling and aims to promote responsible gambling messages towards young Australians, a vulnerable population at risk of gambling-related harm. This study qualitatively evaluated the campaign to gather feedback and understand whether the campaign raised awareness of gambling participation and associated risks. The sample (n = 8) was comprised of young adults in Australia, who were aged between 18 and 24 and were not required to be gamblers to participate. Semi-structured focus groups were conducted and responses were analysed using thematic analysis. Results revealed mainly positive feedback, commenting on the design elements, the messaging, and the dissemination of the campaign. The feedback highlighted likeable features of C’Mon Australia Don’t Let the Game play Ya! and provided suggestions for revisions. This study provides valuable insight to inform the development of future responsible gambling campaigns, and future research is recommended to evaluate the campaign across varying contexts, timeframes, and demographics.
Market Participation of Small-Scale Rice Farmers in Eastern Bolivia
Authors: Lopera Diana C. , Gonzalez Carolina , Martinez Jose M. 
Published: August 2023

AbstractUsing a double-hurdle approach, we assess factors associated with the extent of participation in the rice market with data for small-scale farmers drawn from a nationally representative dataset. The results suggest that larger endowments and assets, animal farming and commercialization, and alternative off-farm income make farmers less likely to participate. Conversely, having access to credit, larger farm sizes, and being part of a farmers’ association all increase the likelihood of participation. Farms with better technological resources are also those with higher sales volumes. Further understanding market participation dynamics should prove useful for deriving evidence-based policy recommendations to strengthen this Bolivian sector.
Effect on damage of aircraft windshield impacted by light UAV with different postures

Published: August 2023

AbstractTo study the performance of the main windshield of a commercial aircraft that has been verified to be airworthy by bird-strike tests against unmanned aerial vehicle (UAV) impact at high-speed, a typical light UAV with various possible flight postures and the main windshield of a commercial aircraft are considered. The transient impact responses at critical moments, energy change and contact force of a multi-layer windshield impacted by a UAV with different postures are investigated using a simulation method based on the models verified by the high-speed impact test between the whole UAV and the full-size nose. This study shows that the flight posture of the UAV has a significant effect on the damage to the windshield. When the abdomen of a typical light UAV maintains a posture parallel to the plane of the windshield, the high-speed impact would cause catastrophic damage to the windshield and no longer be airworthy. Simultaneously, the damage to the aircraft windshield caused by UAV collision is far more serious than that caused by bird strikes under similar collision conditions. The mass-concentrated components of the UAV and their high-hardness characteristics are the main factors of affecting multi-layer glass of windshield damage. The degree of damage to the windshield is positively related to the absorbed energy rather than the impact contact force. In this study, the impact simulation results between the windshield and UAV with different flight postures are verified qualitatively by testing, which provides a rational understanding and technical pre-research support for emerging and increasingly frequent potential safety hazards in air transport practice.
Control of the boundary layer on compressor blade suction surfaces with the momentum jet
Authors: Zheng H. , Zhou Z. , Liu L. 
Published: August 2023

AbstractThe boundary layer thickness on a compressor blade suction surface increases rapidly under a adverse pressure gradient and even separates from the blade surface. This paper proposes a novel method for developing the slot inside the blade, with the inlet of the slot located at the leading edge of the blade and the outlet located at the suction surface, using the momentum of the incoming flow to form a high velocity jet to control the boundary layer on the suction surface. For a plane cascade with a diffusion factor of 0.45, the effects of the main slot parametres (such as the shape of the slot and the positions of the slot inlet and outlet) on the flow in the slot, the flow field and the aerodynamic performance of the cascade were investigated with a numerical method. When the aerodynamic performance of cascades with slotted and unslotted blades was compared, it was found that a reasonable slot structure can effectively inhibit the development of the boundary layer on the blade suction surface and greatly improve the aerodynamic performance of the cascade. Based on the influence of the slot parametres of the above cascade, the slot of a plane cascade with a diffusion factor of 0.60 was designed. The numerical calculation results show that the slotted cascade with a diffusion factor of 0.60 outperformed the slotted cascade with a diffusion factor of 0.45. This result showed that the higher the cascade load, the greater the performance improvement from slotting. Furthermore, the unslotted and slotted cascades were tested, and the test results agreed well with the calculations. The aerodynamic performance of the slotted cascade was better than that of the unslotted cascade, which verifies the accuracy of the calculation method and the feasibility of blade slotting for suppressing the development of boundary layers on suction surfaces and reducing flow loss.
In a Garden of Forking Maps
Authors: Biedermann Zoltán 
Published: August 2023

Abstract
This article compares the cartographical representations
of the Caspian region produced around 1560 in Goa and Venice, with references to
other centers of mapmaking such as Lisbon, Seville, and Antwerp. It explores the
scientific, cultural, technical, and commercial logics that led to profoundly
dissimilar cartographies of the Caspian and its surroundings in different
centers of map production around the same time. It asks questions about the
contrasts between maritime and terrestrial cartography in the Renaissance, and
the cartographical languages associated with each of these cartographical modes.
The habitus of maritime cartographers in Goa, Lisbon, and Seville differed
profoundly, it is argued, from that of mapmakers in Italy, and particularly
Venice, who aimed for an integration of all available data as part of a
tradition of commenting on Ptolemy, and produced highly desirable printed maps
for a growing consumer audience. The article thus advocates a comparative
approach to maps, and critiques the assumption that knowledge “flows” between
regions. It proposes instead a “(dis)connected history” of knowledge production
and consumption to throw new light on the origins of the cartographical printing
revolution.
Sources of seasonal sea-ice bias for CMIP6 models in the Hudson Bay Complex
Authors: Crawford Alex D. , Rosenblum Erica , Lukovich Jennifer V. , Stroeve Julienne C. 
Published: August 2023

AbstractThe seasonal ice-free period in the Hudson Bay Complex (HBC) has grown longer in recent decades in response to warming, both from progressively earlier sea-ice retreat in summer and later sea-ice advance in fall. Such changes disrupt the HBC ecosystem and ice-based human activities. In this study, we compare 102 simulations from 37 models participating in phase 6 of the Coupled Model Intercomparison Project to the satellite passive microwave record and atmospheric reanalyses. We show that, throughout the HBC, models simulate an ice-free period that averages 30 d longer than in satellite observations. This occurs because seasonal sea-ice advance is unrealistically late and seasonal sea-ice retreat is unrealistically early. We find that much of the ice-season bias can be linked to a warm bias in the atmosphere that is associated with a southerly wind bias, especially in summer. Many models also exhibit an easterly wind bias during winter and spring, which reduces sea-ice convergence on the east side of Hudson Bay and impacts the spatial patterns of summer sea-ice retreat. These results suggest that, for many models, more realistic simulation of atmospheric circulation would improve their simulation of HBC sea ice.
Emotions and the Action Analogy: Prospects for an Agential Theory of Emotions
Authors: NAAR HICHEM 
Published: August 2023

AbstractAccording to the action analogy, emotions and actions have certain structural and normative similarities that no theory of emotions should ignore. The action analogy has recently been used in an objection against the so-called perceptual theory of emotions, often defended by means of an analogy between emotion and perception. Beyond the dialectical significance of the action analogy, one might wonder whether it can support a picture of emotions as fundamentally action-like—what I call an agential theory. This article is a first step in answering this question. After discussing various ways to formulate the agential theory, I sketch a version of it.

Published: August 2023

Abstract

Background
Metallic nanoparticles from different natural sources exhibit superior therapeutic options as compared to the conventional methods. Selaginella species have attracted special attention of researchers worldwide due to the presence of bioactive molecules such as flavonoids, biflavonoids, triterpenes, steroids, saponins, tannins and other secondary metabolites that exhibit antimicrobial, antiplasmodial, anticancer and anti-inflammatory activities. Environment friendly green synthesised silver nanoparticles from Selaginella species provide viable, safe and efficient treatment against different fungal pathogens.

Objective
This systematic review aims to summarise the literature pertaining to superior antifungal ability of green synthesised silver nanoparticles using plant extracts of Selaginella spp. in comparison to both aqueous and ethanolic raw plant extracts by electronically collecting articles from databases.

Methods
The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis were taken into consideration while preparing this review. The titles and abstracts of the collected data were stored in Endnote20 based on the inclusion and exclusion criteria. The search strategy included literature from established sources like PubMed, Google Scholar and Retrieval System Online using subject descriptors.

Results
The search yielded 60 articles with unique hits. After removal of duplications, 46 articles were identified, 40 were assessed and only seven articles were chosen and included in this review based on our eligibility criteria.

Conclusion
The physicochemical and preliminary phytochemical investigations of Selaginella suggest higher drug potency of nanoparticles synthesised from plant extract against different diseases as compared to aqueous and ethanolic plant extracts. The study holds great promise as the synthesis of nanoparticles involves low energy consumption, minimal technology and least toxic effects.
When are the natural embeddings of classical invariant rings pure?

Published: August 2023

Abstract
Consider a reductive linear algebraic group G acting linearly on a polynomial ring S over an infinite field; key examples are the general linear group, the symplectic group, the orthogonal group, and the special linear group, with the classical representations as in Weyl’s book: For the general linear group, consider a direct sum of copies of the standard representation and copies of the dual; in the other cases, take copies of the standard representation. The invariant rings in the respective cases are determinantal rings, rings defined by Pfaffians of alternating matrices, symmetric determinantal rings and the Plücker coordinate rings of Grassmannians; these are the classical invariant rings of the title, with

$S^G\subseteq S$

being the natural embedding.
Over a field of characteristic zero, a reductive group is linearly reductive, and it follows that the invariant ring

$S^G$

is a pure subring of S, equivalently,

$S^G$

is a direct summand of S as an

$S^G$

-module. Over fields of positive characteristic, reductive groups are typically no longer linearly reductive. We determine, in the positive characteristic case, precisely when the inclusion

$S^G\subseteq S$

is pure. It turns out that if

$S^G\subseteq S$

is pure, then either the invariant ring

$S^G$

is regular or the group G is linearly reductive.

“Don't Let the Boats Pass!” Neo-Elamite Grain Procurement in Times of Famine and Drought
Authors: Gorris Elynn 
Published: August 2023

AbstractThis article is concerned with interregional trade dynamics between Elam and Mesopotamia in the early to mid-first millennium BC. During the seventh century BC, two great famines in the Neo-Elamite kingdom, of which climatological changes were a major cause, were documented in the textual records. An era of megadrought made grain procurement from the neighboring regions essential to feed the Neo-Elamite lowland population. This article further explores the impact of the two Neo-Elamite famines and “drought of the century” on the commercial and political mechanisms in the Upper Persian Gulf region.
Ice-flow perturbation analysis: a method to estimate ice-sheet bed topography and conditions from surface datasets
Authors: Ockenden Helen , Bingham Robert G , Curtis Andrew , Goldberg Daniel 
Published: August 2023

AbstractOne of the largest contributors to uncertainty in predictions of sea-level rise from ice-sheet models is a lack of knowledge about the bed topography beneath ice sheets. Bed topography maps are normally made by interpolating between linear radar surveys using methods that include kriging, mass conservation and flowline diffusion, all of which may miss influential mesoscale (2–30 km) bedforms. Previous works have explored an Ice-Flow Perturbation Analysis (IFPA) approach for estimating bed topography using the surface expression of these mesoscale bedforms. Using regions of Pine Island Glacier that have been intensively surveyed by ice-penetrating radar as test sites, and a refined IFPA methodology, we find that IFPA detects bedforms capable of influencing ice flow which are not represented in Bedmachine Antarctica and other interpolated bed products. We further explore the ability of IFPA to estimate relative bed slipperiness, finding higher slipperiness in the main trunk and tributaries. Alongside other methods which estimate ice thickness, bed topography maps from IFPA have the potential to constrain projections of future sea-level rise, especially where radar data are sparse.
The relationship between reading and listening anxieties in EFL classrooms: Exploring the mediating effect of foreign language classroom anxiety
Authors: Öztürk Gökhan 
Published: August 2023

AbstractThe purpose of the current study is threefold: (a) to present a descriptive picture of classroom anxiety (FLCA), reading anxiety (FLRA), and listening anxiety (FLLA) in foreign language classrooms; (b) to explore the association between FLCA, FLRA, and FLLA; and (c) to test the mediating effect of FLCA on the relationship between FLRA and FLLA. The participants included 341 tertiary-level students studying at the English Preparatory Program of four public universities in the Turkish EFL context. The data were collected at the beginning of the 2022 fall semester through the Foreign Language Classroom Anxiety Scale, Foreign Language Reading Anxiety Scale, and Foreign Language Listening Anxiety Scale. The descriptive findings indicated a moderate level of FLCA, FLRA, and FLLA among the participants. In addition, significant and positive correlations were found between these three types of anxieties, with the strongest correlation between FLRA and FLLA. In the last stage of the analysis, it was found that FLCA partially and significantly mediated the relationship between FLRA and FLLA. Finally, directions for further research on investigating skill-based anxieties are presented.
Integrating Research Methods Training into Elective Courses in an Undergraduate Curriculum
Authors: Arikan Gizem , Milosav Ðorđe 
Published: August 2023

ABSTRACTThis article discusses the integration of research methods training into a third-year elective undergraduate course. We suggest that the building blocks of research design can be embedded in courses without compromising their content. This introduces research methods to students who have no prior methods training or gives students with methods training more opportunities to engage in research design. We present evidence that this approach increased students’ self-assessed knowledge of and confidence with research-related skills, especially among those without prior methods training. Additionally, the analysis of research proposals—the final assignment of the course—revealed that most students were able to apply core research design skills. These findings demonstrate that progress in research methods skills is possible across the curriculum.
Separation of powers in a globalized democratic society: Theorizing the human rights treaty organs’ interactions with various state organs
Authors: Takata Hinako 
Published: August 2023

AbstractAs part of their continuous effort to enhance the effectiveness and democratic legitimacy of human rights treaties, human rights treaty organs have increasingly fostered a direct relationship with various state organs, thereby penetrating the ‘states’ that traditionally have been treated as monolithic legal entities. Treaty organs review the decision-making process of each type of state organ – courts, parliaments and administrative organs – and make remedial orders that are substantially addressed to specific state organs. Such phenomena go hand in hand with the relativization of the distinction between the legal spheres in which human rights treaty organs and state organs operate. This is the first study to address such phenomena as a totality. It constructs the ‘separation of powers in a globalized democratic society’ theory, thereby proposing how each type of state organ and the treaty organs should interact under human rights treaties. Its findings contribute, first, to the harmonious achievement of the effectiveness and democratic legitimacy of human rights treaties; second, to the reform of the classical paradigm of international law, in which monolithic states are the only relevant legal entities; and third, to the long-standing debates on the relationship between international and national laws from a new angle.
Atmospheric Rivers and Weather Types in Aotearoa New Zealand: A Two‐Way Story
Authors: Pohl Benjamin , Prince Hamish D. , Wille Jonathan , Kingston Daniel G. , Cullen Nicolas J. , Fauchereau Nicolas 
Published: August 2023

AbstractHere, we analyze the inter‐relationships between weather types (WTs) and atmospheric rivers (ARs) around Aotearoa New Zealand (ANZ), their respective properties, as well as their combined and separate influence on daily precipitation amounts and extremes. Results show that ARs are often associated with 3–4 WTs, but these WTs change depending on the regions where ARs landfall. The WTs most frequently associated with ARs generally correspond to those favoring anomalously strong westerly wind in the mid‐latitudes, especially for southern regions of ANZ, or northwesterly anomalies favoring moisture export from the lower latitudes, especially for the northern regions. WTs and ARs show strong within‐type and inter‐event diversity. The synoptic patterns of the WTs significantly differ when they are associated with AR occurrences, with atmospheric centers of actions being shifted so that moisture fluxes toward ANZ are enhanced. The location, angle, and persistence of ARs appear strongly driven by the synoptic configurations of the WTs. Although total moisture transport shows weaker WT‐dependency, it appears strongly related to zonal wind speed to the south of ANZ, or the moisture content of the air mass to the north. Finally, WT influence on daily precipitation may completely change depending on their association, or lack thereof, with AR events. WTs traditionally considered as favorable to wet conditions may conceal daily precipitation extremes occurring during AR days, and anomalously dry days or near‐climatological conditions during non‐AR days.
Statistics of Isolated Deep Convection Initiation and Its Relation to Topography in the North China Area

Published: August 2023

AbstractThis study investigates the statistical characteristics of isolated deep convection initiation (DCI) and its relation to topography in the North China area during the summer season of 2017–2019. A total of 2,534 isolated DCI events are identified using the infrared brightness temperature data from Himawari‐8 satellite with a resolution of 0.05° × 0.05°. The spatial distribution of DCI shows clustering over mountains and hills, indicating that the local topography may be critical for DCI. Topography is described with elevation and relief amplitude in this study. Results show that normalized DCI counts increase with elevation and relief amplitude. For the regime characterized by fewer morning clouds (regime one), DCI strongly depends on elevation and relief amplitude, while for the regime with more morning clouds (regime two), topography only moderately impacts DCI. Linear regression analyses suggest the existence of significant linear relationships between DCI and relief amplitude when elevation is relatively high. Topography is also categorized into four types: plain/sea areas, plateaus, hilly areas, and mountains. Normalized DCI counts show that mountains and hilly areas are more favorable for initiating isolated deep convection, especially for regime one. Moreover, DCI counts in regime one show a stronger diurnal variation and a peak occurring 2 hr earlier than that of regime two. We suggest that special attention should be paid to elevation and relief amplitude, as well as morning cloud cover condition when forecasting DCI in the North China area. Further study is necessary to understand this DCI occurrence preference on specific topography.
