Green Talk or Green Walk: Chinese Consumer Positive Word-of-Mouth to Corporate Environmental Actions in Polluting Industries

Although environmental action is regarded as a public relations strategy aiming to manifest a corporate green stance, this not always the case. Many consumers tend to be skeptical of corporate real environmental efforts, especially firms in traditionally dirty industries. However, few studies have focused on this issue. To shed light on such a phenomenon, the present study aims to provide a comprehensive multiple-step multiple-mediator model based on the social intuitionist model and cognitive-affective system theory of personality(CAPS) to examine how corporate environmental actions (substantive vs. symbolic) affect consumer positive word-of-mouth (WOM) and to investigate the cognitive and affective processes of greenwashing perception and other-condemning emotions. Findings from an online Chinese consumer panel of 130 adults indicate that consumers are prone to have more positive WOM for substantive actions compared with symbolic actions; this effect is not only mediated by other-condemning emotions but serially mediated by, firstly, greenwashing perception and, secondly, other-condemning emotions. The current study is conducive to explaining the link between corporate environmental actions and consumer positive WOM from a theoretical argument and empirical evidence, and thus providing suggestions for advertisers and marketers in green marketing about environmental information disclosure.
Gould’s Icones avium (1837–1838) and vagrancy in the Pennant-winged Nightjar Caprimulgus vexillarius — could it wander to islands in the Indian Ocean?

The Pennant-winged Nightjar Caprimulgus vexillarius was described in 1838 by John Gould from a male in breeding plumage, but its given locality, various islands in the Indian Ocean and Red Sea coasts, was eventually deemed unreliable and replaced in the early 20th century with ‘Sierra Leone’, until the latter too was noticed to be far outside the species’ usual range. Most recently, the type locality has been suggested to be ‘southern Africa’. Using his extensive published correspondence, and other information, I discuss Gould’s contacts and preparation for a monograph of the Caprimulgidae during the mid-1830s. Clues as to where he may have acquired such a specimen are virtually non-existent, and there is no definite evidence to suggest that Gould received it from any of the terra typica mentioned. Nevertheless, the possibility that this species could wander to islands in the Indian Ocean, and elsewhere far outside the usual range, is clearly evidenced by modern sightings and historical specimens.
Mapping the transnational imaginary of social media genres

This article presents a transnational study of the classification and evaluation of social media content. We conducted a large-scale survey (N = 4770) in five countries (Germany, Italy, Japan, South Korea, and the United States) with open-ended questions about the types of content people like and dislike. Through iterative and inductive coding, we identified 29 topics, or broad areas of interest, and 213 recurrent genres, or narrower categories that share elements of form and content. We compared the results according to country, gender, age, and education level, identifying patterns of cultural difference and commonality. While we found significant differences in the prominence and preferentiality of content, these distictions were less pronounced for disliked topics around which social media users tended to converge. Finally, we discuss genre imaginaries as normative maps that reflect ideas about morality in general and the purpose of social media in particular.
Prediction and Suppression of Chaotic Instability in Brake Squeal

Chaotic instability in a vibration phenomenon, known as brake squeal, is investigated including the combined effects of falling friction and mode coupling. Brake squeal is a high-pitched noise that occurs sometimes when a vehicle is decelerated using disk brakes. The equations of motion for the two dominant coupled modes of the brake system reduce to two autonomous coupled nonlinear second order systems. The mode coupling instability via friction causes limit cycle behaviour via a Hopf bifurcation. This limit cycle is shown to break up into chaotic motion characterised by a phase space with an approximate one-dimensional attractor, similar to that found in a forced dry friction oscillator. For the first time, conservative analytical conditions for brake squeal chaos are developed and verified numerically over a range of sprag angles and brake pressures for fundamental and real brake systems. The predictive model is then used to identify and quantify means to suppress brake squeal chaos to unlikely, excessive friction levels. The results provide predictive insight into conditions under which brake squeal chaos occurs and its suppression.
Equilibrium Moisture Content of Wood Estimated Using the Climate Data of Japan

The equilibrium moisture content of wood in Japan is considered to be 15% and is based on weather and experimental data of past years. With the increase of uninhabited weather observation points, weather data has increased over recent years. The objective of this paper was to investigate the recent values of equilibrium moisture content of wood using weather data from 1981 to 1995 for the entire area of Japan.Therefore, contour line maps were used to denote the equilibrium moisture content for the entire year in Japan. The average value of the equilibrium moisture content of Japan was 15%, and the numerical value range was 12‒19%. This value did not change when compared with that reported previously. However, the average value of the equilibrium moisture content of wood changed to 13.5% when compared for the past year the same meteorological stations that had reported previously. equilibrium moisture contour line map, climate data.
Post-COVID 19 Tourism: Will Digital Tourism Replace Mass Tourism?

Recently, nations are struggling to mitigate the impact of the unprecedented COVID-19 outbreak on their economy. Many countries have imposed traveling restrictions to reduce people’s movement in order to avoid infection transmission. Traveling restrictions have jeopardized the tourism industry around the globe. If the situation persists, it will become challenging for the nations to open tourism. For this reason, the digitalization of tourism is a viable solution for this situation. However, it is essential to map whether digital technologies can provide alternative solutions to the situation and whether digital tourism can replace conventional tourism? With that backdrop, this study has two objectives: (a) to find the future of digital tourism development beyond the COVID-19 pandemic situation, and (b) to find collaborative research work among nations to develop digital tourism after the current pandemic crisis. To achieve these objectives, we conducted a systematic literature review of past research on the development of digital tourism from 2016–2020. The study applies the PRISMA-2015 statement to select and synthesize 60 articles from Scopus and ‘Web of Science’ databases. Content analysis was performed to analyze the underlying clusters of research on digital tourism and, later, bibliometric analysis was conducted to examine collaborative research between different countries. The findings highlighted three major research clusters namely; virtual reality tourism, virtual tourism, and augmented reality. In addition, the research finding shows that virtual tourism is a practical and valuable option for mass tourism during the COVID-19 outbreak and can replace mass tourism after the pandemic. Although virtual tourism does not feel like a visit to a natural destination, it is still getting attention from tourists. Virtual spaces must develop more features and value additions to achieve tourist satisfaction in the future.
Similar yet distinct distributional patterns characterize native and exotic plant species richness across northern New Zealand islands

A better understanding of plant invasions on islands can be gained from comparing patterns of exotic and native species richness. We asked four questions: (1) Is exotic species richness on islands related to native species richness? (2) If they are related, does this result from similar responses of native and exotic species to specific island characteristics? (3) Is residual variation in native‐exotic richness relationships associated with distinctive island characteristics? (4) Are relationships between species richness and island characteristics scale‐dependent, and do they differ between native and exotic species?
Comparing the Slider Measure of Social Value Orientation with Its Main Alternatives

The Slider Measure of social value orientation (SVO) was introduced as an improvement from existing measures. We conduct an independent assessment of its suitability compared with the Ring Measure and the Triple Dominance Measure. Using a student sample, we assess the measures’ test-retest reliability (N = 88; using a longer time interval than previous studies) and sensitivity to random responses. Analyses pertaining to convergent validity, criterion validity, and the advantages of a continuous over a discrete measure are presented in the online appendix. Compared with alternatives, the Slider Measure has the highest test-retest reliability. However, it classifies random responses in an unbalanced way, assigning the vast majority of random responses to cooperative and individualistic, rather than altruistic and competitive, orientations. For all three measures, we propose improved ways of weeding out inconsistent responses.
Preparation and synchronous participation improve student performance in a blended learning experience

Blended learning can create flexibility for students, more efficiently utilise infrastructure, and can provide high-quality learning at scale. We investigated perceived value and learning gains associated with asynchronous eLearning and synchronous face-to-face (f2f) components of a blended learning experience. We hypothesised that individual student preference for eLearning and f2f learning would be variable, but that participation in f2f classes would enhance student learning. Using a design-based research approach, we have evaluated two iterations of a blended learning experience, combining qualitative survey data and quantitative attendance data and student grades. Students overwhelmingly valued active learning, both within eLearning materials and f2f classes. Final marks positively correlated with the number of f2f classes students attended. Analysis of a subset of intended learning outcomes (ILOs) showed that students who accessed eLearning independently and students who attended f2f classes performed equally-well in ILO-related assessment tasks, however, students were more likely to choose an assessment task directly-related to a class they attended. In addition, completion of required eLearning prior to f2f class attendance significantly enhanced student performance in related assessment tasks. We suggest that f2f attendance as part of blended learning is beneficial, however students can obtain selected ILOs from engaging eLearning materials. Implications for practice or policy: Instructors will gain insight into aspects of blended active learning that students value. We present evidence that supports the benefits to students of completion of pre-eLearning prior to participation in synchronous f2f classes.
The exact annihilating-ideal graph of a commutative ring

The rings considered in this article are commutative with identity. For an ideal $I$ of a ring $R$, we denote the annihilator of $I$ in $R$ by $Ann(I)$. An ideal $I$ of a ring $R$ is said to be an exact annihilating ideal if there exists a non-zero ideal $J$ of $R$ such that $Ann(I) = J$ and $Ann(J) = I$. For a ring $R$, we denote the set of all exact annihilating ideals of $R$ by $\mathbb{EA}(R)$ and $\mathbb{EA}(R)\backslash \{(0)\}$ by $\mathbb{EA}(R)^{*}$. Let $R$ be a ring such that $\mathbb{EA}(R)^{*}\neq \emptyset$. With $R$, in [Exact Annihilating-ideal graph of commutative rings, {\it J. Algebra and Related Topics} {\bf 5}(1) (2017) 27-33] P.T. Lalchandani introduced and investigated an undirected graph called the exact annihilating-ideal graph of $R$, denoted by $\mathbb{EAG}(R)$ whose vertex set is $\mathbb{EA}(R)^{*}$ and distinct vertices $I$ and $J$ are adjacent if and only if $Ann(I) = J$ and $Ann(J) = I$. In this article, we continue the study of the exact annihilating-ideal graph of a ring. In Section 2 , we prove some basic properties of exact annihilating ideals of a commutative ring and we provide several examples. In Section 3, we determine the structure of $\mathbb{EAG}(R)$, where either $R$ is a special principal ideal ring or $R$ is a reduced ring which admits only a finite number of minimal prime ideals.
The Impact of Amount of Cu on CO2 Reduction Performance of Cu/TiO2 with NH3 and H2O

This study has investigated the impact of molar ratio of CO2 to reductants NH3 and H2O as well as that of Cu loading on CO2 reduction characteristics over Cu/TiO2. No study to optimize the reductants’ combination and Cu loading weight in order to enhance CO2 reduction performance of TiO2 has been investigated yet. This study prepared Cu/TiO2 film by loading Cu particles during the pulse arc plasma gun process after coating TiO2 film by the sol-gel and dip-coating process. As to loading weight of Cu, it was regulated by change in the pulse number. This study characterized the prepared Cu/TiO2 film by SEM and EPMA. Additionally, the performance of CO2 reduction has been investigated under the illumination condition of Xe lamp with or without ultraviolet (UV) light. It is revealed that the molar ratio of CO2/NH3/H2O is optimized according to the pulse number. Since the amount of H+ which is the same as that of electron is needed to produce CO decided following the theoretical CO2 reduction reacting with H2O or NH3, larger H+ is needed with the increase in the pulse number. It is revealed that Cu of 4.57 wt% for the pulse number of 200 is the optimum condition, whereas the molar quantity of CO per unit weight of Cu/TiO2 with and without UV light illumination is 34.1 mol/g and 12.0 mol/g, respectively.
Female in top management and firm performance nexus: Empirical evidence from Ghana

Abstract This study investigates empirically the link between females in top management and firm performance in Ghana. This study employs the Instrumental Variable (IV) Two Stage Least Squares (2SLS) technique of estimation in determining the impact of females in top management on firm performance using World Bank Enterprise Survey (WBES) data across 720 firms in Ghana. This technique is very robust as it has the power to control for any possible endogeneity bias, which can lead to spurious results. After controlling for reverse causality, our results reveal that the inclusion of females in top management impacts positively on firm performance in Ghana. We further note that though innovation has direct positive impact on firm performance, there is no evidence of any moderating roles played by innovation or education in the link between female in top management and firm performance in Ghana. The results of our study should however be interpreted with a bit of caution as we have not been able to examine the time dynamics of our findings due to lack of reliable panel data. Apart from serving as a reference literature for future studies, the study is very useful to both government and firms who make decisions in respect of females in management.
The Adoption of Big Data Analytics Among Manufacturing Small and Medium Enterprises During Covid-19 Crisis in Malaysia

Global epidemic Coronavirus Disease 2019 (COVID-19) has a significant impact on the global economy. The Big Data Analytics (BDA), which helps businesses to obtain useful insights, is seen as a new strategic weapon in industry particularly during this challenging time. This study investigated the influence of technological factors on BDA adoption among Malaysian manufacturing Small and Medium Enterprises (SMEs). The data was collected from 185 manufacturing SMEs in Malaysia and analysed using SmartPLS version 3.3. 2. This study uncovers significant technological factors that drive BDA adoption and highlight the role of technological resource competency as a mediator in this model. The findings contribute to the Malaysian SMEs to strategize BDA adoption in today’s dynamic business environment, and can be a reference to ASEAN developing nations as well.

The most frequent comorbidities were hypertension, diabetes, as well as cardiovascular and cerebrovascular diseases (13.1%, 7.4 %, and 5.9% respectively). The majority of the patients in this study were male, the most prevalent signs and symptoms were fever, cough, and fatigue. The highly repeated comorbidities in the cases were hypertension, diabetes, also cardiovascular and cerebrovascular diseases.
Chemistry of Fe(II) in the presence of organic exudates from phytoplankton and of copper in seawater

Chemistry of Fe(II) in the presence of organic exudates from phytoplankton and of copper in seawater Aridane Gonzalez Gonzalez La oxidacion de Fe(II) en agua de mar ha sido estudiada en presencia de altas concentraciones de nutrientes, exudados organicos y de cobre en agua de mar. Los resultados experimentales obtenidos en la presente Tesis Doctoral evidencian la fragilidad de la quimica del Fe(II) en el medio marino, mostrando una fuerte interaccion con los nutrientes mayoritarios (nitratos, fosfatos y silicatos) comunmente utilizados en estudios de laboratorio, tambien presentes en altas concentraciones en zonas costeras. De los tres nutrientes estudiados, el Si(OH)4 es el principal responsable del incremento observado en la constante de velocidad de oxidacion para el Fe(II). El efecto que desempenan los compuestos organicos exudados por el fitoplancton se estudio para dos especies, Phaeodactylum tricornutum y Dunaliella tertiolecta. En ambos la velocidad de oxidacion de Fe(II) disminuyo en presencia de exudados organicos, siendo funcion del pH, la temperatura y la salinidad. Ademas, esta disminucion describio una importante dependencia lineal con la densidad celular existente en el cultivo experimental. En todos los casos estudiados se desarrollo un modelo cinetico teorico que describiera los resultados experimentales, con el que se puede conocer la especiacion del Fe(II) y la contribucion de cada una de las especies de Fe(II) a la velocidad total del proceso de oxidacion, bajo las condiciones experimentales consideradas en cada estudio. De estos modelos se extrae que la especie Fe(H3SiO4)+ juega un papel importante en condiciones de altas concentraciones de silicatos, tanto en la especiacion como en la velocidad del proceso. Pero ademas, los compuestos organicos que se han considerado en dicho modelo, juegan un papel fundamental, tanto en la especiacion de Fe(II) como en la contribucion de las especies complejadas organicamente de Fe(II) al proceso global de oxidacion. El efecto competitivo entre Fe(II) y cobre ha sido tambien estudiado en esta Tesis Doctoral, para lo que tuvo que ser estudiado previamente la cinetica de oxidacion de Cu(I) a nivel nanomolar en agua de mar. En este caso, se obtuvo una fuerte dependencia de la velocidad de oxidacion de Fe(II) con la concentracion de Cu(II) en la disolucion. En todos los casos, tanto en funcion del pH, la concentracion de bicarbonato como la concentracion de peroxido de hidrogeno, la velocidad de oxidacion de Fe(II) aumento con la concentracion de Cu(II). Los resultados obtenidos en esta Tesis Doctoral permiten profundizar en la quimica del Fe(II) en agua de mar, pero ademas abre numerosas puertas para incrementar el conocimiento del ciclo biogeoquimico del Fe(II) en aguas naturales.
Investigating the Roles of Implicit and Explicit Knowledge in the Production of Grammatical Errors

This research aims to investigate the role of implicit and/or explicit knowledge in the production of grammatical errors in academic texts. Explicit knowledge is defined as conscious and declarative knowledge used to monitor language production while implicit knowledge is defined as an intuitive knowledge which enables the second language learners to use the language spontaneously without any reflection (Zhang, 2015). The reasons why this research is conducted is due to the fact that the students are still producing errors even though they have learnt English since elementary school. The data is gained from the academic text written down by fifteen English department students studying in a university in Jakarta. It is analyzed by using two different measurements: (1) Delayed Grammatical Judgment Tests (GJT), and (2) Interview including Metalingual Comment to investigate the role of explicit knowledge in the production of grammatical errors. The other two measurements are also used; they are (1) Timed Grammaticality Judgment Test (TGJT), and (2) Oral Production Test (OPT) to investigate the role of implicit knowledge. The results show that 19.2% of grammatical errors are produced due to the implicit knowledge and 80.8% is due to explicit knowledge. Since the explicit knowledge plays an important role in producing the grammatical errors, it can be concluded that teaching English grammar for university students is still important. If possible, the English Grammar lessons should be given more rooms in the overall curriculum
Infinite use of finite means? Evaluating the generalization of center embedding learned from an artificial grammar

Human language is often assumed to make "infinite use of finite means" - that is, to generate an infinite number of possible utterances from a finite number of building blocks. From an acquisition perspective, this assumed property of language is interesting because learners must acquire their languages from a finite number of examples. To acquire an infinite language, learners must therefore generalize beyond the finite bounds of the linguistic data they have observed. In this work, we use an artificial language learning experiment to investigate whether people generalize in this way. We train participants on sequences from a simple grammar featuring center embedding, where the training sequences have at most two levels of embedding, and then evaluate whether participants accept sequences of a greater depth of embedding. We find that, when participants learn the pattern for sequences of the sizes they have observed, they also extrapolate it to sequences with a greater depth of embedding. These results support the hypothesis that the learning biases of humans favor languages with an infinite generative capacity.
