The form and function of joint attention within joint action

ABSTRACT Joint attention is an everyday phenomenon in which two or more individuals attend to an object, event process or property in the presence of each other, such that their attention to that object is to some degree intertwined with the other’s attention to it. This paper argues that joint attention has the normative role of enabling subjects to coordinate their actions in a way that would contribute to the rational execution of a joint action in accordance with a prior shared plan or shared intention. This understanding of the normative function of joint attention underpins a particular understanding of the nature of joint attention: what I shall call Rich Relationalism. Rich Relationalism argues for the view that joint attention acts as an epistemically significant interface between the world, other people, and their background plans and concepts. It understands joint attention as an object-dependent, conceptually structured, token experiential state that is shared by two (or more) people. It can be contrasted with non-relational (i.e., Representational or Enactivist) accounts of joint attention on the one hand, and Lean Relationalist accounts on the other (such as John Campbell’s influential account).
Identification of Data -Intensive Systems Requirements Using Semantic Similarity Search

The phenomenal growth of big data in social applications and IT software platforms over the last few decades has emphasized the significance of a systematic requirement engineering strategy for analyzing the requirements of data-intensive systems, that deliver valuable insights to business entities. Classification of data-intensive requirements can aid in the development of a more systematic and transparent requirements engineering process, resulting in increased requirement compliance and software project completion. As a result, this paper provides a unique approach Word2Vector based Fast Similarity Search (WV-FaSS) for improving the process of software requirement categorization for data-intensive systems in two phases. Word2Vec begins by taking a corpus of software requirements as input and producing a well-trained high-dimensional vector space. Following that, the vectors that were extracted semantically are indexed. The query vector is then used to look for the most similar vectors within the index, and lastly, similar documents are obtained. Experiments on two benchmark datasets, PURE and WARC, as well as a dataset from the private IT industry, demonstrated that our model outperformed state-of-the-art techniques with precision, recall, and F1 values of 0.91, 0.9, and 0.9, respectively. Thus, the proposed model WV-FAISS enables developers to rapidly search for embeddings of similar requirements that are similar to one another , while also increasing the scalability of similarity search methods.
A simplified methodology for dynamic responses of cross-decks of trimarans under slamming loads

ABSTRACT The design principle of the hull structure is to ensure sufficient strength and avoid excessive waste of materials. The equivalent dynamic coefficients (EDC) possess the advantages of both static analysis and dynamic analysis in engineering. However, there is still no clear method for determining the EDC of a trimaran. In this work, the EDC of the cross-decks are chosen as the research objects. The EDC of the plate, longitudinal girders, and transverse frame of the cross-decks are calculated respectively. A method considering material nonlinearity and a method considering transverse bending moment (TBM) are proposed, and the effect of elastic-plastic material and TBM on EDC is presented. Results show that it is feasible to use the EDC to analyze the trimaran under slamming loads. Besides, the EDC of different parts of the trimaran is different, hence it is not recommended to use the fixed value given by the ABS rules.
Association between corticolous myxomycetes and tree vitality in Cryptomeria japonica

The bark of live trees provides an important microhabitat for corticolous myxomycetes. However, the association between the presence of myxomycetes and health of host trees has not been studied in detail. In this study, we aimed to investigate the relationship between tree vitality and myxomycetes on the bark of Cryptomeria japonica trees in a montane forest in western Japan. The vitality of trees was categorized into four grades based on the visual assessment of tree shape and leaf density in the upper branches. Myxomycetes on the bark surface were examined using the moist chamber culture method. A decline in tree vitality increased bark pH and decreased electrical conductivity of the bark exudates. Seventeen myxomycete species were recorded in 74 C. japonica trees. The structure of myxomycete communities varied between healthy and unhealthy trees, and species diversity increased as the vitality declined. The relative abundance of Cribraria confusa decreased as the vitality declined, while that of Paradiacheopsis solitaria increased. The results showed that acidophilic myxomycetes grew on healthy C. japonica bark, but changes in bark pH associated with vitality decline led to the weakening of acidity and shifted the community structure; thus, corticolous myxomycete diversity was enhanced as tree vitality decline.
Low‐pH seawater alters indirect interactions in rocky‐shore tidepools

Abstract Ocean acidification is expected to degrade marine ecosystems, yet most studies focus on organismal‐level impacts rather than ecological perturbations. Field studies are especially sparse, particularly ones examining shifts in direct and indirect consumer interactions. Here we address such connections within tidepool communities of rocky shores, focusing on a three‐level food web involving the keystone sea star predator, Pisaster ochraceus, a common herbivorous snail, Tegula funebralis, and a macroalgal basal resource, Macrocystis pyrifera. We demonstrate that during nighttime low tides, experimentally manipulated declines in seawater pH suppress the anti‐predator behavior of snails, bolstering their grazing, and diminishing the top‐down influence of predators on basal resources. This attenuation of top‐down control is absent in pools maintained experimentally at higher pH. These findings suggest that as ocean acidification proceeds, shifts of behaviorally mediated links in food webs could change how cascading effects of predators manifest within marine communities.
Titmice are a better indicator of bird density in Northern European than in Western European forests

Abstract Population sizes of many birds are declining alarmingly and methods for estimating fluctuations in species’ abundances at a large spatial scale are needed. The possibility to derive indicators from the tendency of specific species to co‐occur with others has been overlooked. Here, we tested whether the abundance of resident titmice can act as a general ecological indicator of forest bird density in European forests. Titmice species are easily identifiable and have a wide distribution, which makes them potentially useful ecological indicators. Migratory birds often use information on the density of resident birds, such as titmice, as a cue for habitat selection. Thus, the density of residents may potentially affect community dynamics. We examined spatio‐temporal variation in titmouse abundance and total bird abundance, each measured as biomass, by using long‐term citizen science data on breeding forest birds in Finland and France. We analyzed the variation in observed forest bird density (excluding titmice) in relation to titmouse abundance. In Finland, forest bird density linearly increased with titmouse abundance. In France, forest bird density nonlinearly increased with titmouse abundance, the association weakening toward high titmouse abundance. We then analyzed whether the abundance (measured as biomass) of random species sets could predict forest bird density better than titmouse abundance. Random species sets outperformed titmice as an indicator of forest bird density only in 4.4% and 24.2% of the random draws, in Finland and France, respectively. Overall, the results suggest that titmice could act as an indicator of bird density in Northern European forest bird communities, encouraging the use of titmice observations by even less‐experienced observers in citizen science monitoring of general forest bird density.
Qualitative methods show that surveys misrepresent “ought implies can” judgments

ABSTRACT Experimental philosophers rely almost exclusively on quantitative surveys that potentially misrepresent participants’ multifarious judgments. To assess the efficacy of qualitative methods in experimental philosophy and reveal limitations with quantitative surveys, a study was conducted on the Kantian principle that ‘ought implies can’, which limits moral obligation to actions that agents can do. Specifically, the think aloud method and a follow-up interview were employed in a modified version of a prominent experiment that recorded participants’ judgments of ability, blame, and obligation using quantitative surveys. The modified version produced quantitative results similar to the original experiment along with qualitative data that reveal that the surveys fundamentally misrepresented participants’ judgments. The qualitative transcripts from 40 participants are analyzed to show that ‘ought implies can’ judgments are complex and multifarious, that ‘ought implies can’ judgments are misrepresented by quantitative survey questions, and that the majority of participants uphold or preserve ‘ought implies can. ’ The results suggest that experimental philosophers can more accurately capture judgments by using qualitative methods, and that studies which rely on quantitative surveys possibly misrepresent participants’ judgments.
Adaptive Random Spatial based Channel Estimation (ARSCE) for Millimeter Wave MIMO System

Millimeter-wave and mMIMO communications are the most essential success systems for next-generation wireless sensor networks to have enormous amounts of accessible throughput and spectrum. Through installing huge antenna arrays at the base station and performing coherent transceiver processing, mMIMO is a potential technology for enhancing the bandwidth efficiency of wireless sensor networks. The use of mmWave frequencies for mMIMO systems solves the problem of high path-loss through offering greater antenna gains. In this work, we provide a design with a random spatial sample structure that incorporates a totally random step before the analogue is received. It contains a totally random step before the analogue received signals are sent into the digital component of the HBF receiver. Adaptive random spatial based channel estimation (ARSCE) is proposed for channel session measurement collection, and an analogue combiner with valves has been used to estimate the signals at each receiving antenna. The proposed optimization problem formulation attempts to discover the orientations and gains of wideband channel routes. In addition, our proposed model has compared to various state-of-art techniques while considering error minimization.
Parameter and quantile estimation for the distributions of failure strength of structural lumber

Estimating various characteristics, such as selected quantiles or the parameters, of a probability distribution of structural lumber failure strength is critical to quality control during manufacturing operations and for reliability-based structural design. This paper presents and compares the performances (in terms of bias and root mean square error) of several alternative estimation methods when censored strength data are used in the statistical estimation process. This study concludes that the method of maximum likelihood is nearly universally superior to a regression method that appears to be in wide use in the lumber industry. Recommendations are made about the use of alternative strategies for implementing the maximum likelihood method. The results of this work will be valuable when selecting the best estimation method for a particular set of circumstances. The results also establish the foundation for a computer program that will use a rule-based expert system to facilitate the estimation process.
Combustion Turbine F-Class Life Management of 1st Stage Turbine Blades

Whenever the operations and maintenance economics so dominate the operation of a particular power producer, engineering insight is the plant’s vanguard in maintaining and managing costs. To provide a basis for operators to confront the spiraling parts replacement costs that are so closely tied to the durability of the hot section, EPRI has developed the Gas Turbine Life Management Platform (LMP), an effort which has been directly supported by F-Class turbine operators. Tested and verified on the advanced 7FA and 9FA class of turbine designs, the LMP provides unprecedented detail on temperatures and stresses throughout a selected hot section component. In turn, the platform relies on explicit details of stress and temperature to track the damage due to creep, coating oxidation and TMF (thermal mechanical fatigue). Supplied with operating data, it graphically represents the recent practices of either base load or peaking service. The platform supplies the engineering data needed by operators to make informed decisions regarding the disposition (continued use, repair, or scrap) of these most advanced and expensive parts. In this paper, the procedures of predicting temperature/life and how well these predictions correlated with field observations will be discussed in detail. © 2002 ASME
Comparing, Differentiating, and Applying Affective Facial Coding Techniques for the Assessment of Positive Emotion

ABSTRACT Coding of facial expressions is a simple, fast, inexpensive, and straightforward method to complement self-report research. This approach is particularly relevant for assessing psychological factors such as positive emotion that may be particularly susceptible to self-report biases. The goals of this paper are to 1) provide convincing evidence that this well-validated method should be used in emotion research and 2) provide information about specific facial coding techniques to investigators who are looking to incorporate these methods into their research. We discuss the value, strengths, weaknesses, and applications of four techniques: facial electromyography (EMG), the Facial Action Coding System (FACS), computerized approaches, and modified/simplified hand coding techniques. Taken together, this paper provides a foundation from which researchers can integrate comprehensive and objective assessments of positive emotion into their investigations of human behavior and lays the groundwork for future research to build upon these facial analysis techniques.

A new species of the eurypterid Hibbertopterus from the Carboniferous of New Mexico, and a review of the Hibbertopteridae

ABSTRACT Hibbertopterus lamsdelli sp. nov., from the Late Carboniferous Kinney Quarry Lagerstätte of New Mexico (USA), is a large (ca. 1.1 m long) stylonurid eurypterid (sea-scorpion; Chelicerata), similar to H. scouleri from Scotland but with less serrate segment margins, a wider pretelson, shorter telson (tail-spine), and more parallel ventral keels. It is only the fourth, yet most reliable record of an American hibbertopterid. A taxonomic reassessment of Hibbertopterus regards Dunsopterus and Vernonopterus (but not Cyrtoctenus) as synonyms. Hibbertopterids were aquatic (benthic) scavengers and microphagous sweep-feeders, but their trackways indicate that they were capable of brief terrestrial, seasonal nuptial walks, despite their large size; Hibbertopterus had walking legs with spinose extensions at the base (Laden) to spread their load, and the ventral keels on their telson functioned like sled rails to reduce body drag. Hibbertopterids were interpreted as moving into freshwater during the Late Palaeozoic, but a trackway from the middle Permian Collingham Formation (Ecca Group) of South Africa may be from a marine setting, though further analysis is needed to fully evaluate this possibility.
Revealing subsurface processes in the Uhlířská catchment through combined modelling of unsaturated and saturated flow

A novel transferable modelling approach was applied to reveal subsurface flow processes and thus complement, verify, and enhance the conceptual knowledge of the small (1.78 km2) mountainous experimental catchment Uhlířská in the northern part of the Czech Republic. We used the S1D model to simulate flow and tracer movement in the vadose zone. MODFLOW‐2000, MODPATH and MT3DS models were used to determine residence time and flow trajectories in the saturated zone. The isotopic tracers 3H and 3H/3He were used to calibrate the groundwater model in the deeper aquifer layers. The modelling approach was established to enhance our understanding and quantification of interactions between the hillslope (82% of the area) and wetland (18% of the area), as well as the aquifer beneath the catchment. Numerical methods corroborated the estimated groundwater residence times and provided a catchment water balance in support of process knowledge. The combined modelling yielded the following water balance for the period 1961–2014: 1220 mm annual precipitation amount, 456 mm of percolation through the soil matrix domain on hillslopes, 534 mm of water through the hillslope preferential domain, and 22 mm of water through the matrix of the riparian wetland. This partitioning resulted in an area‐weighted average annual groundwater recharge of 430 mm. The water residence time on the hillslopes did not exceed 1 year, and was about 10 years for the saturated zone, with 20% of water older than 100 years in the deepest part of the aquifer. The conceptual knowledge of subsurface hydrological processes combined with numerical modelling, computation of water balance and isotope‐supported calibration is considered innovative, particularly the 3H/3He method to determine water residence times of young groundwater in the saturated zone. Lessons learned and recommendations are presented to apply the knowledge from the Uhlířská in the broad context of small research catchments.
A ‘New Arms Race’? Framing China and the U.S.A. in A.I. News Reporting: A Comparative Analysis of the Washington Post and South China Morning Post

This study explores the news framing of A.I., China, and the U.S.A. in two mainstream news outlets: The Washington Post and The South China Morning Post. The main objective is to analyse how both, as parts of different discourse cultures, portray the competition for leadership in A.I. innovation between China and the U.S.A. The study takes a critical look at the media discourse on the ‘new arms race’ and what role the news play in localising global technology trends. The empirical part makes use of a combination of manual and automated content analyses. To this end, a dictionary approach that utilises Names Entity Recognition was applied to a large volume of news texts (N = 3.055) to identify recurring news frames. The findings show similarities in the perception of A.I.’s potentials and versatility but also clear cultural differences in how risks and conflicts are portrayed in both outlets. Although the Washington Post appears more critical about A.I., the South China Morning Post frames the technology as a driver of economic growth and global influence. The discussion offers a starting point for theorising the relationship between mediatisation, tech trends, cultural differences, and international politics.
On design and realization of new generation mission-critical application systems

On Design and Realization of New Generation Misson-critial Application Systems. (May 2011) Zhibin Mai, B.S.; M.S., Shanghai Jiao Tong University Chair of Advisory Committee: Dr. Wei Zhao Mission-critical system typically refers to a project or system for which the success is vital to the mission of the underlying organization. The failure or delayed completion of the tasks in mission-critical systems may cause severe financial loss, even human casualties. For example, failure of an accurate and timely forecast of Hurricane Rita in September 2005 caused enormous financial loss and several deaths. As such, real-time guarantee and reliability have always been two key foci of mission-critical system design. Many factors affect real-time guarantee and reliability. From the software design perspective, which is the focus of this paper, three aspects are most important. The first of these is how to design a single application to effectively support real-time requirement and improve reliability, the second is how to integrate different applications in a cluster environment to guarantee real-time requirement and improve reliability, and the third is how to effectively coordinate distributed applications to support real-time requirements and improve reliability.
Lifetime Maximization for 5G Mobile Networks using Secured and Finest Optimal Routing Protocol

Enhancing the network lifetime is mandate since to increase the efficiency of the network and to improve their performance. However reliable routing in wireless mobile network is the most significant problem that exists. Therefore offering mobility characteristic to each and every node’s in the networks requires a new meaning for the lifetime of network. In this research article, joint optimization mechanism called Secured and Finest Optimal Routing (SFOR) protocol is proposed. When the mobile node’s routing is indefinite or unidentified in Software Defined Network (SDN) then the three cases of routing problem is formulated for deriving secured and finest optimal routing which aims in lifetime maximization. All the three cases may be modelled as linear programming (LP) problems which can be solved as the source node routing progresses. Further for mobile node’s routing which is definite or precise, the reference energy value is set to balance the network lifetime. The proposed SFOR protocol is simulated and the performance is compared with the existing scheme. From the performance analysis it is observed that the proposed SFOR protocol enhance the network lifetime 50% and 16% as compared with Route Selection based on Connectivity, Delay, and Trust (RSCDT) and Virtual Ad hoc Routing Protocol (VARP) respectively.
A motivação social da haplologia variável no português de Porto Alegre

O artigo trata da motivação social da haplologia sintática variável (dentro de casa::den’de casa, voltando de carro::voltan’de carro) no português brasileiro falado em Porto Alegre, capital do estado do Rio Grande do Sul. A análise quantitativa de dados de fala (cf. LABOV, 1972, 1994, 2001, 2010), de caráter exploratório, verifica que o processo, aplicado a sílabas iniciadas por /t/ ou /d/ em posição final e inicial de palavras em sequência na frase, (a) ocorre numa proporção total de 27,2% na fala de jovens; (b) correlaciona-se às variáveis sociais Mobilidade entre zonas e Renda e à variável linguística Estrutura da segunda sílaba. Os resultados sugerem que os efeitos de mobilidade na haplologia variável no português de Porto Alegre devam-se à persona jovem urbana cosmopolita que o processo, como recurso de identificação e distinção (cf. ECKERT 2000, 2018), auxilia a compor.
