Authors: Nguyen Ha , Lopez John , Homer Bruce , Ali Alisha , Ahn June 
Published: March 2023

PurposeIn the USA, 22–40% of youth who have been accepted to college do not enroll. Researchers call this phenomenon summer melt, which disproportionately affects students from disadvantaged backgrounds. A major challenge is providing enough mentorship with the limited number of available college counselors. The purpose of this study is to present a case study of a design and user study of a chatbot (Lilo), designed to provide college advising interactions.Design/methodology/approachThis study adopted four primary data sources to capture aspects of user experience: daily diary entries; in-depth, semi-structured interviews; user logs of interactions with the chatbot; and daily user surveys. User study was conducted with nine participants who represent a range of college experiences.FindingsParticipants illuminated the types of interactions designs that would be particularly impactful for chatbots for college advising including setting reminders, brokering social connections and prompting deeper introspection that build efficacy and identity toward college-going.Originality/valueAs a growing body of human-computer interaction research delves into the design of chatbots for different social interactions, this study illuminates key design needs for continued work in this domain. The study explores the implications for a specific domain to improve college enrollment: providing college advising to youth.

Authors: Rahman Nida , Sharma Krishan 
Published: March 2023

PurposeRegional comprehensive economic partnership (RCEP) is understood as the world's largest trading bloc given its contribution to the world output (30%). The mega trade bloc brings together 15 countries of East Asia, Southeast Asia and Oceania to eliminate tariff and non-tariff barriers in goods and services trade. The study suggests the importance of sector specific reforms for Malaysia to strengthen domestic capability.Design/methodology/approachThe analytical framework constructs upon the partial equilibrium analysis and uses WITS SMART simulations.FindingsThe study finds that Malaysia's elimination of tariffs under the RCEP will cause a surge in imports from developed member countries of RCEP like Australia, South Korea and Japan. The study also finds a trade diversion in countries such as India. The empirical results establishes that RCEP would further strengthen intra-ASEAN trade.Research limitations/implicationsThe study explores select sectors of the manufacturing industry in Malaysia.Practical implicationsThe implementation of RCEP would impact the manufacturing sector immensely, especially in sectors like electrical machinery and equipment and inorganic chemicals, which are two of the major trading commodities of the Malaysian economy.Social implicationsAny trade agreement has a larger impact on the society. It may raise income, boost the consumer preferences and create or erode consumer welfare. The study reports the consumer welfare effect of the implementation of RCEP in Malaysia.Originality/valueThe study is the first attempt to do a partial equilibrium analysis for the electrical machinery and equipment sector and inorganic chemicals sector of Malaysia using both aggregated and disaggregated data at HS two-digit and HS six-digit level.

Abstract

Protecting deep‐sea coral‐based vulnerable marine ecosystems (VMEs) from human impacts, particularly bottom trawling, is a major conservation challenge in world oceans. Management processes for these ecosystems are weakened by key uncertainties that could be substantially addressed by having much greater volumes of quantitative image‐derived data that detail the distribution and abundance of coral reefs and the nature of impacts upon them. Considerably greater volumes of data could be available if the resource costs of image annotation are reduced.

In this paper we propose a solution: a deep learning system capable of automatically identifying reef‐building stony corals amongst other seabed substrata in much larger volumes of seabed imagery than was previously possible. Using a previously annotated dataset, we trained a convolutional neural network on approximately 70,000 classified images (‘snips’) comprising six benthic substrate classes, including reef‐building stony coral—‘coral matrix’.

Model performance improvements, chiefly by dataset cleaning, transfer learning and hyperparameter optimisation, resulted in the final trained model achieving validation accuracy of 98.19%. The classification was robust: benthic substrate types were accurately differentiated, and in some cases more consistently than was achieved by human annotators.

Synthesis and applications. The availability of much larger volumes of automatically annotated image‐derived data will improve spatial management of impacts on coral‐based VMEs in the deep sea by (1) improved cross‐validation and performance of spatial models required to predict coral distribution and abundance over the large scales of managed areas, and (2) establishing empirical relationships between coral abundance on the seabed and coral bycatch landed during fishing operations.
Litter accumulation, not light limitation, drives early plant recruitment

Abstract

Theory predicts a decline in grassland diversity under nutrient enrichment and loss of herbivory, and one possible cause is hampered seedling recruitment. Two potential drivers for reduced diversity at the seedling level are diminished light availability caused by surrounding vegetation and accumulation of dead biomass.

To test the importance of these two mechanisms on early recruitment, we added seeds of 15 herbaceous grassland plant species and monitored sown and natural seedling emergence during one growing season in a full factorial field experiment with light addition and litter removal under fertilization and exclusion of mammalian herbivores in an experimental grassland in Central Germany. We used modern LED lamps, mimicking the spectrum of natural sun light, to provide light to small‐statured understorey plants. This novel experimental set‐up allowed us to specifically disentangle the roles of light limitation and litter accumulation independently and in combination.

In general, herbivore exclusion, but not fertilization increased the amount of litter biomass. Litter removal increased seedling number and richness by 83% and 33%, respectively, while light addition had no significant main effect on seedling recruitment, nor did it interact with any other factors, and did not affect recruitment even when litter was removed. In addition, fertilization had a negative and herbivore exclusion a negligible impact on recruitment, and these effects were independent of litter removal. Furthermore, seedling number and richness were unrelated to light intensity and quality, litter depth, soil moisture, temperature and C:N ratio.

Synthesis: These results provide novel insights into the role of light limitation versus litter accumulation driving early recruitment and help understanding the mechanisms that affect diversity in grassland communities via recruitment. Our results highlight the detrimental role of litter accumulation as opposed to surrounding vegetation induced light deficiency driving early recruitment from seeds and call for management actions that reduce the amount of litter when maintaining or restoring diversity.

AbstractStygofauna are aquatic fauna that have evolved to live underground. The impacts of anthropogenic climate change, extraction and pollution on groundwater pose major threats to groundwater health, prompting the need for efficient and reliable means to detect and monitor stygofaunal communities. Conventional survey techniques for these species rely on morphological identification and can be biased, labour‐intensive and often indeterminate to lower taxonomic levels. By contrast, environmental DNA (eDNA)‐based methods have the potential to dramatically improve on existing stygofaunal survey methods in a large range of habitats and for all life stages, reducing the need for the destructive manual collection of often critically endangered species or for specialized taxonomic expertise. We compared eDNA and haul‐net samples collected in 2020 and 2021 from 19 groundwater bores and a cave on Barrow Island, northwest Western Australia, and assessed how sampling factors influenced the quality of eDNA detection of stygofauna. The two detection methods were complementary; eDNA metabarcoding was able to detect soft‐bodied taxa and fish often missed by nets, but only detected seven of the nine stygofaunal crustacean orders identified from haul‐net specimens. Our results also indicated that eDNA metabarcoding could detect 54%–100% of stygofauna from shallow‐water samples and 82%–90% from sediment samples. However, there was significant variation in stygofaunal diversity between sample years and sampling types. The findings of this study demonstrate that haul‐net sampling has a tendency to underestimate stygofaunal diversity and that eDNA metabarcoding of groundwater can substantially improve the efficiency of stygofaunal surveys.

Published: March 2023

AbstractSpatially explicit densities of wildlife are important for understanding environmental drivers of populations, and density surfaces of intraspecific classes allow exploration of links between demographic ratios and environmental conditions. Although spatially explicit densities and class densities are valuable, conventional design‐based estimators remain prevalent when using camera‐trapping methods for unmarked populations.We developed a density surface model that utilized camera trap distance sampling data within a hierarchical generalized additive modelling framework. We estimated density surfaces of intraspecific classes of a common ungulate, white‐tailed deerOdocoileus virginianus, across three large management regions in Indiana, United States. We then extended simple statistical theory to test for differences in two ratios of density.Deer density was influenced by landscape fragmentation, wetlands and anthropogenic development. We documented class‐specific responses of density to availability of concealment cover, and found strong evidence that increased recruitment of young was tied to increased resource availability from anthropogenic agricultural land use. The coefficients of variation of the total density estimates within the three regions we surveyed were 0.11, 0.10 and 0.06.Synthesis and applications. Our strategy extends camera trap distance sampling and enables managers to use camera traps to better understand spatial predictors of density. Our density estimates were more precise than previous estimates from camera trap distance sampling. Population managers can use our methods to detect finer spatiotemporal changes in density or ratios of intraspecific‐class densities. Such changes in density can be linked to land use, or to management regimes on habitat and harvest limits of game species.
Preferences for facial sexual dimorphism is related to frequency of pornography consumption among heterosexual‐identifying men and homosexual‐identifying men: A mediating role of sociosexuality

Published: March 2023

AbstractFrequent consumption of sexually explicit material (SEM) on the internet may influence attitudes toward sex (e.g., sociosexuality), and sociosexuality may influence people's preferences for potential partners' facial dimorphism. However, few studies have focused on the association between dimorphism preference and pornography consumption, and fewer have examined it in heterosexual‐identifying and homosexual‐identifying men. A total of 234 heterosexual‐identifying and 133 homosexual‐identifying men were asked to respond to questions regarding their preferences toward facial dimorphism, sociosexual orientation, and frequency of viewing SEM. Frequency of SEM consumption was related to sociosexuality and preference for potential partners' sex‐typical facial features, sociosexuality worked as a full mediator in this relationship, and similar mediating associations were found among heterosexual‐identifying and homosexual‐identifying men. The results identified associations between consumption of pornographic material and sexual dimorphic preference for the first time. Findings suggest not only that homosexual‐identifying men prefer masculinity in same‐sex partners but also that the sexual script theory that pornographic material consumption may influence men's short‐term relationship orientation among sexual minorities and under a conservative sexual culture. This study contributes to the understanding of the preference for facial dimorphism from a perspective on social learning and mate choice.

AbstractAimsOnce widely used across Europe, grazing of hay meadows is now a rare agricultural practice that is mainly applied in rural regions with maintained traditional agriculture. In this review, we examine the knowledge on grazing hay meadows in the Carpathian Mountains, including its historical distribution, implementation and timing, potential impacts on grassland productivity and biodiversity, and implications for grassland conservation and restoration.LocationThe Carpathian Mountains (43.8–50.1°N, 16.9–27.1°E).MethodsWe conducted a literature review including biological, ecological, agricultural, ethnological, and historical sources.Results and ConclusionsIn each of the seven farming systems that existed in parallel in the Carpathian Mountains before agricultural intensification, grazing of hay meadows was applied regularly. Spring, autumn, and occasionally summer grazing, along with corralling and manuring of hay meadows, were integral parts of these systems, adapted to the seasonal movement of dairy farms across various agroecosystems. The data reviewed provide insight into the role of animals in hay meadow management, as well as how the breakdown of these historical farming systems is impacting local biodiversity, the economy, and the community. According to the literature sources, grazing hay meadows has numerous positive impacts on grassland biodiversity, including suppressing fast‐growing competitors, reducing the accumulation of litter, increasing the availability of germination gaps, dispersing seeds through zoochory, supporting ground‐nesting birds through later mowing, and promoting the regeneration of plants from seeds. From this perspective, the combination of mowing and grazing can be considered a promising tool in current grassland conservation and restoration efforts.
New axioms for top trading cycles

Published: March 2023

AbstractThe school choice problem is of great importance both in theory and practice. This paper studies the (student‐optimal) top trading cycles mechanism (TTCM) in an axiomatic way. We introduce two new axioms: MBG (mutual best group)‐quota‐rationality and MBG‐robust efficiency. While stability implies MBG‐quota rationality, MBG‐robust efficiency is weaker than robust efficiency, which is stronger than the combination of efficiency and group strategy proofness. The TTCM is characterized by MBG‐quota rationality and MBG‐robust efficiency. Our results construct a new basis to compare the TTCM with the other school choice mechanisms, in terms of both fairness and incentive‐related axioms.

AbstractLimb‐girdle muscular dystrophy recessive 1 (LGMDR1), previously known as LGMD2A, is a specific LGMD caused by a gene mutation encoding the calcium‐dependent neutral cysteine protease calpain‐3 (CAPN3). In our study, the compound heterozygosity with two missense variants c.635 T > C (p.Leu212Pro) and c.2120A > G (p.Asp707Gly) was identified in patients with LGMDR1. However, the pathogenicity of c.635 T > C has not been investigated. To evaluate the effects of this novel likely pathogenic variant to the motor system, the mouse model with c.635 T > C variant was prepared by CRISPR/Cas9 gene editing technique. The pathological results revealed that a limited number of inflammatory cells infiltrated the endomyocytes of certain c.635 T > C homozygous mice at 10 months of age. Compared with wild‐type mice, motor function was not significantly impaired in Capn3 c. 635 T > C homozygous mice. Western blot and immunofluorescence assays further indicated that the expression levels of the Capn3 protein in muscle tissues of homozygous mice were similar to those of wild‐type mice. However, the arrangement and ultrastructural alterations of the mitochondria in the muscular tissues of homozygous mice were confirmed by electron microscopy. Subsequently, muscle regeneration of LGMDR1 was simulated using cardiotoxin (CTX) to induce muscle necrosis and regeneration to trigger the injury modification process. The repair of the homozygous mice was significantly worse than that of the control mice at day 15 and day 21 following treatment, the c.635 T > C variant of Capn3 exhibited a significant effect on muscle regeneration of homozygous mice and induced mitochondrial damage. RNA‐sequencing results demonstrated that the expression levels of the mitochondrial‐related functional genes were significantly downregulated in the mutant mice. Taken together, the results of the present study strongly suggested that the LGMDR1 mouse model with a novel c.635 T > C variant in the Capn3 gene was significantly dysfunctional in muscle injury repair via impairment of the mitochondrial function.
The Role of Implicit and Explicit Beliefs in Grave‐Good Practices: Evidence for Intuitive Afterlife Reasoning
Authors: Swan Thomas , Bering Jesse , Hughes Ruth , Halberstadt Jamin 
Published: March 2023

AbstractThe practice of burying objects with the dead is often claimed as some of the earliest evidence for religion, on the assumption that such “grave goods” were intended for the decedents’ use in the afterlife. However, this assumption is largely speculative, as the underlying motivations for grave‐good practices across time and place remain little understood. In the present work, we asked if explicit and implicit religious beliefs (particularly those concerning the continuity of personal consciousness after death) motivate contemporary grave‐good practices. Across three studies, and comparing participants from the United States and NZ, we measured grave‐good deposition at actual or hypothetical funerals, finding that jewelry, photographs, and other items with sentimental, emotional, and relationship value were common. In addition, intuitive afterlife reasoning (as measured by people's attributions of mental states to the dead) motivated grave‐good decision‐making for about half (Study 2) or more (Study 3) people, including afterlife nonbelievers (“extinctivists”), while those who held explicit (i.e., stated) afterlife beliefs were more likely to participate in the practice. The decision to leave grave goods was also associated with magical contagion beliefs and a need for personal comfort, while other motivations, such as social signaling, were less common. Our results suggest that “afterlife use” is a common motivation for grave‐good practices, and that humans possess evolutionarily early intuitions about postdeath consciousness.

AbstractAimTo determine whether isolated low‐grade germinal matrix‐intraventricular haemorrhages (LG‐GMH‐IVH) and low‐grade punctate cerebellar haemorrhages (LG‐CBH) contribute to the neurodevelopment of infants born preterm with very low birthweight (VLBW).MethodA prospective observational cohort study was conducted on infants born with VLBW hospitalized from January 2012 to July 2017 who had undergone serial cranial ultrasounds since birth and magnetic resonance susceptibility‐weighted imaging of the brain at term‐corrected age. Only those with VLBW carrying isolated LG‐GMH‐IVH (grades 1 or 2) or isolated LG‐CBH (punctate cerebellar haemorrhages ≤4 mm in diameter) or absence of lesions (no‐lesion) were enrolled and followed up to 3 years. The Griffiths Mental Development Scales, Extended and Revised version (GMDS‐ER), were used to assess neurodevelopment, considering unsatisfactory scores less than 85. Behaviour, according to the criteria of the International Classification of Diseases, 10th Revision, and rehabilitation data were noted.ResultsTwo‐hundred and forty infants with VLBW were enrolled: 34 with LG‐GMH‐IVH, 17 with LG‐CBH, and 189 as no‐lesion. The LG‐GMH‐IVH and LG‐CBH groups scored worse than the no‐lesion group on all GMDS‐ER scores for 1 year, 2 years, and 3 years. The LG‐CBH group scored lower than the LG‐GMH‐IVH group for total GMDS‐ER scores at 1 year and 2 years but not at 3 years. At 3 years, compared with the LG‐CBH group, those with LG‐GMH‐IVH received less and later physical therapy, with more frequent attention problems. The odds ratio for unsatisfactory GMDS‐ER scores corrected for gestational age was 5.75 for LG‐CBH (95% confidence interval 1.92–17.25; p = 0.002) and 2.67 for LG‐GMH‐IVH (95% confidence interval 1.16–6.13; p = 0.02).InterpretationLow‐grade haemorrhages affect the neurodevelopment of very‐low‐birthweight infants. Early rehabilitation might have contributed to their development.What this paper adds

Low‐grade haemorrhages seem to have an independent role in the adverse neurodevelopment of infants born extremely preterm.
Infants born preterm with low‐grade germinal matrix‐intraventricular haemorrhage (LG‐GMH‐IVH) are indicated for physical therapy at a later age than those with low‐grade punctate cerebellar haemorrhage (LG‐CBH).
Compared with LG‐CBH, LG‐GMH‐IVH is associated with a greater extent of attention problems at 3 years corrected age.
