Intention to use analytical artificial intelligence (AI) in services – the effect of technology readiness and awareness

PurposeThe automation of services is rapidly growing, led by sectors such as banking and financial investment. The growing number of investments managed by artificial intelligence (AI) suggests that this technology-based service will become increasingly popular. This study examines how customers' technology readiness and service awareness affect their intention to use analytical AI investment services.Design/methodology/approachThe automation of services is rapidly growing, led by sectors such as banking and financial investment. The growing number of investments managed by AI suggests that this technology-based service will become increasingly popular. This study examines how customers' technology readiness and service awareness affect their intention to use analytical AI investment services.FindingsThe results indicated that customers' technological optimism increases, and insecurity decreases, their intention to use robo-advisors. Surprisingly, feelings of technological discomfort positively influenced robo-advisor adoption. This interesting finding challenges previous insights into technology adoption and value co-creation as analytical AI puts customers into a very passive role and reduces barriers to technology adoption. The research also analyzes how consumers become aware of robo-advisors, and how this influences their acceptance.Originality/valueThis is the first study to analyze the role of customers' technology readiness in the adoption of analytical AI. The authors link the findings to previous technology adoption and automated services' literature and provide specific managerial implications and avenues for further research.
Good option or only option? Poverty, disability, health and enterprise

PurposeThis paper aims to explore experiences of poverty in the enterprise amongst people with a disability or long-term health challenges. This paper departs somewhat from established wisdom about economic or financial drivers of enterprise by exploring why a disabled individual would start and continue to operate in a business where that business is providing income-poverty. In so doing, it subscribes to the idea that the enterprise involves reflexive engagement of an agent in context where value(s) of the enterprise other than financial may be prioritised.Design/methodology/approachThe research draws from a larger qualitative study of self-employment and poverty in which half the sample (21 individuals) identified as experiencing disability or poor health. Semi-structured interviews were conducted these participants and a thematic analysis with specific reference to Theory of Venturing, which proposes that the value of enterprise is reflexively and idiosyncratically understood and morphogenetic, was used to explore itinerant issues, experiences and challenges.FindingsIn line with the theory, findings include that disability and poor health are observed to be both prompters and shapers of an enterprise and that the value of enterprise is not always primarily associated with financial wealth for the participants in the sample. Flexibility and autonomy are attractive features of self-employment for some in the face of an inflexible and sometimes hostile labour market.Originality/valueThis paper demonstrates that engaging in enterprise is motivated by an agent's reflexive evaluation of value(s) and how that enables them to navigate their structural condition(s); this contribution enhances theoretical approaches to enterprise and business creation by illuminating some of its diversity. This paper also contributes some much needed data about a group who are under-represented in the enterprise literature despite being over-represented in practice. There are implications and recommendations for policy and practice in the exposure and analysis of the issues emerging.
Class formation and class struggle in la convention, Peru

This paper has as its object the analysis of class formation, class struggle and its effects in the province of La Convention, Peru. The first section of the paper examines this process at the level of the province as a whole during the 1940–68 pre‐agrarian reform period, while the second and third sections focus on the same process in more detail as it relates to one particular rural estate during the period between 1973 and 1975 following the agrarian reform. The fourth section examines the question of political practice arising from the analysis elaborated in the two previous sections.
A Narration-based Reward Shaping Approach using Grounded Natural Language Commands

While deep reinforcement learning techniques have led to agents that are successfully able to learn to perform a number of tasks that had been previously unlearnable, these techniques are still susceptible to the longstanding problem of reward sparsity. This is especially true for tasks such as training an agent to play StarCraft II, a real-time strategy game where reward is only given at the end of a game which is usually very long. While this problem can be addressed through reward shaping, such approaches typically require a human expert with specialized knowledge. Inspired by the vision of enabling reward shaping through the more-accessible paradigm of natural-language narration, we develop a technique that can provide the benefits of reward shaping using natural language commands. Our narration-guided RL agent projects sequences of natural-language commands into the same high-dimensional representation space as corresponding goal states. We show that we can get improved performance with our method compared to traditional reward-shaping approaches. Additionally, we demonstrate the ability of our method to generalize to unseen natural-language commands.
Shannon capacity and the categorical product

Shannon OR-capacity $C_{\rm OR}(G)$ of a graph $G$, that is the traditionally more often used Shannon AND-capacity of the complementary graph, is a homomorphism monotone graph parameter therefore $C_{\rm OR}(F\times G)\leqslant\min\{C_{\rm OR}(F),C_{\rm OR}(G)\}$ holds for every pair of graphs, where $F\times G$ is the categorical product of graphs $F$ and $G$. Here we initiate the study of the question when could we expect equality in this inequality. Using a strong recent result of Zuiddam, we show that if this "Hedetniemi-type" equality is not satisfied for some pair of graphs then the analogous equality is also not satisfied for this graph pair by some other graph invariant that has a much "nicer" behavior concerning some different graph operations. In particular, unlike Shannon OR-capacity or the chromatic number, this other invariant is both multiplicative under the OR-product and additive under the join operation, while it is also nondecreasing along graph homomorphisms. We also present a natural lower bound on $C_{\rm OR}(F\times G)$ and elaborate on the question of how to find graph pairs for which it is known to be strictly less than the upper bound $\min\{C_{\rm OR}(F),C_{\rm OR}(G)\}$. We present such graph pairs using the properties of Paley graphs.
Influence of calcium concentrations on the metabolic profile of dairy goats during the transitional period

In order to differentiate groups of hypocalcemic (G1) and normocalcemic animals (G2) and infer the influence of subclinical hypocalcemia on metabolic profiles, this study determined calcium concentrations during the transitional period in 35 dairy goats healthy, pregnant, primiparous or multiparous, crossbreed or pure-bred dairy goats producing average 3 kg/day/goat. Therefore, blood samples were collected before (30, 20 and 10 days before parturition), on the day of delivery and after parturition (10, 20, 30, 40, 50 and 60 days postpartum). The variables measured were glucose, nonesterified fatty acids, β-hydroxybutyrate, cholesterol, triglycerides, amylase, total protein, albumin, urea, creatinine, aspartate aminotransferase, gamma glutamyl transferase, creatine kinase, total calcium, phosphorus, magnesium, chlorides, cortisol and insulin, as well as ionized calcium (Ca++), sodium and potassium. Goats were considered to have subclinical hypocalcemia if Ca++ ≤0.72 mmol/L. The data were analyzed by ANOVA. In subclinically hypocalcemic goats, serum concentrations of Ca++ decreased earlier (10dbp) than in normocalcemic goats (parturition) and remained lower throughout the transitional period (p=0,004). Among the measured variables, Ca++ showed greater influence on the NEFA, glucose, insulin and total calcium but also influenced the protein profile. Lower food intake by goats with subclinical hypocalcemia was one of the main factors interfering with the metabolic profile and likely the productivity of these animals. Studies should be conducted to measure the effects of subclinical disease on the production rates and on the emergence of other transitional period diseases.
The reliability and validity of the sport engagement instrument in the Finnish dual career context

ABSTRACT Although engagement is key to predicting burnout and dropout, few existing instruments measure this phenomenon in the sports context. As part of a larger three-year Lower Secondary Sports Schools Pilot Project (LSSSPP) in Finland, we conducted two studies as part of the present research with the major aims of (a) constructing the Sport Engagement Instrument (SpEI) and (b) validating the new instrument in the Finnish dual career context. In the preparatory study, an expert panel constructed the SpEI, a questionnaire comprising 37 items intended to measure cognitive and affective sports engagement. The main study utilised questionnaire data collected from two independent samples (n 1 = 992 and n 2 = 465) of lower secondary school student athletes aged 13 and 14 years to validate the SpEI. Six competing factorial structures with differing numbers and subsets of the 37 items were analysed using a series of confirmatory factor analyses. The results indicate that 18 items dispersed along with four affective engagement factors and either two first-order or one second-order cognitive engagement factor described the sports engagement phenomenon most accurately in both samples. Higher levels of sport burnout correlated negatively and behavioural engagement positively with affective and cognitive dimensions of engagement, which supported the instrument’s validity. Although further validation is needed, the SpEI, in combination with coach and parental observations of changes in behavioural signs, might be useful in identifying athletes with low sports engagement and developing subsequent interventions accordingly.
Analysis of the Use of a Wind Turbine as an Energy Recovery Device in Transport Systems

A wind turbine can act as an energy recovery device (ERS) in a comparable way to brakes (regenerative braking). When the velocity of a vehicle changes, the amount of energy related to it also changes. When its velocity decreases, the energy tends to dissipate. Over time, this dissipated energy has been ignored. For example, during the braking process, the kinetic energy of the vehicle was converted into heat. In recent years, society’s greater awareness of climate change, pollution, and environmental issues has led to a great deal of interest in developing energy recovery systems. It allows the recovery of kinetic energy from braking (KERS), resulting in consumption reductions (efficiency gains) of up to 45%. The usefulness of installing a wind turbine as an energy recovery device is analysed, evaluating the savings that can be achieved with its two possible working modes: as an energy recovery device and as a system for utilizing aerodynamic force. The wind turbine has a horizontal axis and a diameter of 50 cm and is installed on the front of a vehicle. This vehicle will undergo three particular driving schemes, which will operate under different experimental conditions and operational parameters characterized by speeds, accelerations, stops, and driving time. The results clearly show the advantages of using the proposed technology.
Isolation and identification of Pseudomonas entomophila from Pinus massoniana and its insecticidal activity against Monochamus alternatus

ABSTRACT To identify microorganisms that can colonise pine trees and have a toxic effect on Monochamus alternatus (Coleoptera: Cerambycidae), we isolated the CSHH2 bacterial strain from the phloem of nematode-infected Pinus massoniana (Coniferales: Pinaceae). The isolated strain was identified as Pseudomonas entomophila (Pseudomonadales: Pseudomonadaceae) based on phenotypic traits, 16S rDNA gene sequencing, homology analysis, phylogenetic tree analysis, and physiological and biochemical analysis. P. entomophila CSHH2 was resistant only to cefathiamidine and polymyxin B but was sensitive to most drugs tested in the antimicrobial sensitivity assay. Furthermore, the bioassay indicated that the CSHH2 strain possesses significant insecticidal activity against the second instar larvae of M. alternatus (p < 0.0001). LC50 and LT50 were 5.37 × 107 CFU mL−1 and 5.630 days (1.63 × 108 CFU mL−1 bacteria per larva) respectively at 10 days post-treatment. The present study is the first to identify the toxicity of P. entomophila against M. alternatus larvae.
A Cultural Orientation Approach to Work Orientation: Mongolian Workers’ Jobs, Careers, and Callings

Culturally held beliefs about the self and its relations with others affect the way individuals view their work. In this study, we examined the associations between individualism-collectivism and the three work orientations (i.e., viewing work as a job, a career, or a calling). We also investigated whether the positive effects of a calling orientation can be generalized to a developing eastern country, Mongolia. Using a sample of 352 Mongolian workers, we found that those endorsing horizontal collectivism tended to view their work as a calling more than as a job or a career. Mongolians with a calling orientation reported having better satisfaction with job, salary, and life, more work meaningfulness, and less turnover intention than those viewing work as a job or a career. The results suggest that cultural orientations and work orientations are intertwined, and the positive roles of a calling orientation are generalizable to Mongolia.
Robust finite‐iteration tracking of discrete‐time systems in repetitive process setting via ILC scheme

In this work, based on the robust iterative learning control (ILC) scheme, the finite‐iteration tracking control is investigated for discrete‐time linear systems in repetitive process setting with external disturbances. First, the concept of finite‐iteration tracking is defined. Then by utilizing the lifted‐vector‐matrix technique, the discrete‐time linear system can be reformulated as an input–output transmission equation. Moreover, a P‐type ILC scheme is employed, and then the finite‐iteration tracking of the resultant system is guaranteed with the designed iterative learning controller. Meanwhile, the settling iteration can be explicitly obtained. Particularly, the case of data loss occurred during information transmission is also studied, and sufficient conditions are presented such that the finite‐iteration tracking can be achieved in a finite interval. Lastly, the effectiveness and applicability of the presented method are validated via a numerical simulation.
Impact of Governance Factors over Lecturers’ Scientific Research Output: An Empirical Evidence

This study aims to determine the governance factors that influence the scientific research output of lecturers through the application of PLS-SEM, in conjunction with ANOVA and t-test. Based on a survey of 398 lecturers in twelve higher education institutions (HEIs) in Vietnam, the psychometric properties of the scales measuring the considered dimensions of scientific research outputs were initially examined through the Exploratory Factor Analysis (EFA) procedure, prior to being input into the PLS-SEM model. The SEM model comprised six constructs for the scientific research outputs: scientific research objectives of HEIs, leadership, decentralization, policies for lecturers, support for scientific research activities, and resources for scientific research. The results reveal that resources for scientific research have the most impact on lecturers’ scientific research output, followed by policies for lecturers, support for scientific research activities, scientific research objectives of HEIs, and finally, leadership.
Boys, science and literacy: place-based masculinities, reading practices and the ‘science literate boy’

ABSTRACT The fields of science and literacy education continue to be shaped by pervasive gender inequality. Previous research has documented how the formation of a ‘science identity’ is contingent on access to science capital while research in literacy education continues to highlight how boys struggle in their literacy acquisition. Despite a robust scholarship on gendered literacy practices and gender in STEM subjects, to date, there has been little investigation of the relationships between boys’ science identity/ies and their literacy practices. We draw on a case study of 24 middle school boys living and learning in two different regions (e.g. metropolitan, rural) where we focus on how boys conceive of themselves as learners in two curriculum areas: science and literacy. Bridging multiple areas of scholarship (e.g., science literacy, science identity, boys in schooling), we concentrate on the participants’ self-belief in science and self-belief as readers and consider the way they inform each other in reference to place. The implications of our study concern how the science literate boy comes to be in reference to the construction of discursive performances of science masculinities and how they are maintained alongside literate identities.
Discourse Markers in Hausa Proverbs: Exploring Intellectual Wise Saying from African Wisdom and Culture

This paper aims to explore some intellectual wise saying from African wisdom and culture from one of the three major languages in the northern part of Nigeria. The use of discourse markers is one of the linguistics devices embedded in Hausa proverbs. However, Africa as the continent was occupied by different languages and dialectics. Proverbs is an expression of a saying which combines various wisdom and culture of every human beings living on the earth. This paper utilises written document as a method and selected (36) different proverbs and analyses the discourse markers. Moreover, the paper reviewed various studies that looked at proverbs' role as one of a figurative speech and the definitions of discourse markers defined by literary scholars and cultural critics who studied proverbs from different perspectives. The finding of this paper identified (19) out of (36) proverbs also indicated DMs served as interpersonal functions and the relationship between the speakers’ actions and thoughts, while the remaining (17) functions as textual features for making meaning. Finally, the study found that discourse markers enhance some lexical expressions under different levels, including sentence connectivity, language use, and the appearance of discourse markers in the proverbs. The study's significance shows that cultural scholars and English language educators can incorporate/integrate proverbs and highlighted the role of discourse markers to the student, enhancing their linguistics knowledge, communication skills and learning activities.
Effects of cellulose nanofiber content on impact properties of carbon fiber reinforced epoxy composites with the cellulose nanofiber dispersion layer

Abstract Cellulose nanofibers (CNFs) are environmentally friendly materials with a high specific strength. To enhance the impact properties of the carbon fiber reinforced plastics (CFRPs), a method for inserting a CNF dispersion layer between prepregs was developed. By using an aqueous solution of epoxy resin, the hydrophobic treatment of CNF became unnecessary. In this study, CFRP with CNF dispersion layers was fabricated with different CNF content. The impact energy absorbed by the CFRP specimen was increased with the increasing CNF content, and the Charpy impact value increased up to a maximum of 21% by the CNF dispersion layers. Highlights Carbon fiber reinforced plastics (CFRPs) specimens with the cellulose nanofiber (CNF) dispersion layer were fabricated. The specimens were fabricated by varying the content of CNF. Impact energy absorbed by the CFRP specimen was increased with increased CNF content. Charpy impact value increased up to 21%; optimum ductility index value was clarified.
Youth-Focused Programs in Collectivist Cultures: Can Youth-Focused Intervention Lead to Significant Change in Vulnerable Rural Communities in Armenia?

Abstract This study aims to evaluate whether community-based and individual interventions in Armenia lead to improvements in youth outcomes. Youth from eight schools were invited to participate in a community-based intervention plus a program targeting youth beliefs and behaviors, and youth from eight other schools were invited to participate in the community-based intervention alone. In total, 240 youths aged 10–16 years (M = 12.48; SD = 1.33) agreed to participate. There were significant increases in perceived sociopolitical control in both groups, and in emotional regulation through cognitive reappraisal in the community-based intervention-only group. The only significant change identified in the individual intervention group in comparison to the community-based intervention only group was a lower uptake of beliefs endorsing wife-beating. No other improvements were found. Our research failed to find support for brief interventions targeting the individual beliefs and behaviors of Armenian youth, indicating that multilevel interventions which are sustained over time may be needed.
Dual-Band Dual-Mode Patch Antenna With High-Gain and Wide-Beam Radiations in Two Respective Bands

In this article, a novel dual-band dual-mode (DBDM) patch antenna is proposed with flexible radiation coverage and a simple structure. Distinct radiation properties with high-gain in the lower band and wide-beam in the upper band could be attained under a small frequency ratio and a single element. The working principle of the wide-beam radiation is, for the first time, proposed and theoretically analyzed based on the electric current calculation, providing a good insightful understanding of the radiation of the inverse currents. The high-gain radiation in the lower band is realized by introducing the shunt inductive effect while maintaining a negligible influence on the upper band. In terms of realization, a pair of stubs and shorting pins are properly loaded on a square patch to achieve the conditions required in the theoretical analysis. It indicates that the proposed method could be easily achieved with the simple structure of a single layer and a single element. Additionally, further discussion on the size reduction of the patch is provided with good cross-polarization. Two prototypes are finally designed, fabricated, and tested. The simulated and measured results exhibit good agreement with each other, certifying the validity of the proposed method. All these attractive merits, such as flexible coverage with high-gain and wide-beam radiations, simple structure with a single element, small achievable frequency ratio, and low profile, demonstrate that the proposed antenna could be a good potential candidate in the modern wireless systems.
