Authors: Ivaldi Silvia , Scaratti Giuseppe , Fregnan Ezio 
Published: July 2021

PurposeThis paper aims to address the relevance and impact of the fourth industrial revolution through a theoretical and practical perspective. The authors present both the results of a literature review, highlighting the new competences required in innovative workplaces and a pivotal case, which explores challenges and skill models diffused in industry 4.0, describing the role of proper organizational learning processes in shaping new work cultures.Design/methodology/approachThe paper aims to enhance the discussion around the 4.0 industrial revolution addressing both a theoretical framework, valorizing the existing scientific contributes and the situated knowledge, embedded in a concrete organizational context in which the fourth industrial revolution is experienced and practiced.FindingsThe findings acquired through the case study endorse what the scientific literature highlights about the impact, the new competences and the organizational learning paths. The conclusions address the agile approach to work as the more suitable way to place humans at the center of technological progress.Research limitations/implicationsThe paper explores a specific organizational context, related to a high-tech multinational company, whose results illustrate the empirical evidence sustaining transformations in the working, professional and organizational cultures necessary to face the challenges of the fourth industrial revolution. The research was conducted with the managers of an international company and this a specific and limited target, even though relevant and interesting.Practical implicationsThe paper connects the case with the general scenario, this study currently faces, to suggest hints and coordinates for crossing the unfolding situation and finding suitable matching between technological evolution and the development of new work and professional cultures and competences.Social implicationsDue to the acceleration that the COVID-19 has impressed to the use of digital technologies and remote connexion, the paper highlights some ambivalences that the quick evolution of the new technologies entails in relation to work and social conditions.Originality/valueThe opportunity to match both a literature analysis and an in-depth situated case study enhances the possibility to achieve a more articulated and complex view of the viral changes generated in the current context by the digitalization process.
Understanding environmental tweets of for-profits and nonprofits and their effects on user responses
Authors: Shin Sumin , Ki Eyun-Jung 
Published: July 2021

PurposeOrganizations are communicating with the public about their thoughts and behaviors relevant to the environment via social networking sites. The purpose of this paper is to explore for-profit and nonprofit organizations' Twitter messages to understand their environment-related messages and their influences on the publics' responses.Design/methodology/approachThis study conducted a content analysis adopting four message classification systems: environmental message orientation, message specificity, message framing, and environmental issue. Guided by attribution theory, this study also explored how the organization's environmental messages influence social media (Twitter) user responses, likes, retweets, and replies.FindingsThe analysis showed that for-profits' messages tend to discuss their green products and manufacturing processes with specific numeric evidence, while nonprofits are disposed to describe a severely degraded environment. In addition, the study revealed that tweets yield a high number of likes and replies when the organizations are for-profits and the messages emphasize green products.Research limitations/implicationsThe findings of this study showed that the green message categorization systems are applicable to the social media context. But, this study focused on Twitter only. Future studies need to examine various social media platforms.Practical implicationsThe study findings recommend communication practitioners use substantive green messages highlighting actual pro-environmental performances. Also, practitioners might need to make a linkage between the discussed environmental issue and the organization (e.g. a water issue by a wildlife-related nonprofit, an energy issue by a home appliance manufacturer, an air pollution issue by a bicycle company). In addition, regarding the message specificity, infographics can be present specific information that audiences can readily understand because it is described visually.Originality/valueScholars investigated environmental messages in advertising and cautioned that environmental messages that are not substantive or specific can cause audiences to perceive the messages as greenwashing. However, these previous studies focused on conventional media, and they have not been replicated in the age of social media. Thus, it is important to explore the current status of organizational environmental messages on social media.
The mixed spin-3/2 and spin-2 Blume-Capel model by renormalization group approach
Authors: El Kihel Karima , Saadi Hasnae , Aharrouch Rachid , El Antari Abdelmoumen , Hachem Nabil , Madani Mohamed , El Bouziani Mohammed 
Published: July 2021

PurposeThe authors investigate the magnetic properties of a mixed spin-3/2 and spin-2 Blume-Capel model on square and cubic lattices with two different single-ion anisotropies.Design/methodology/approachTo study the critical behavior of a mixed spin-3/2 and spin-2 system, the authors have used a real space renormalization group approximation and specifically the Migdal-Kadanoff technique. The authors give the phase diagrams for two different cases: (1) on the (Δ/|J|, 1/|J|) plane with ΔA = ΔB = Δ, and (2) on the (ΔA/|J|, 1/|J|) and (ΔB/|J|, 1/|J|) planes for selected values of ΔB/|J| and ΔA/|J|, respectively.FindingsThe phase diagrams obtained show that the system exhibits both second- and first-order phase transitions as well as tricritical points for some values of the anisotropies. Moreover, using the variation of the free energy and its derivative at low temperatures, the authors have seen the appearance of first-order transitions at very low temperatures.Originality/valueFew investigations of mixed spin-3/2 and spin-2 systems with crystal field have been realized. For this reason, the authors use the renormalization group approach to complete the work done on these systems. In absence of an exact solution, this contributes to the synthesis of the approximation results on mixed spins models.
What constitutes quality to students in higher education? An empirical investigation of course-level student expectations
Authors: Tóth Zsuzsanna , Bedzsula Bálint Péter 
Published: July 2021

Purpose
The purpose of this paper is to identify and interpret the critical quality attributes of core educational services at the course level both with student and lecturer involvement. Significant differences between the viewpoints of these two directly involved stakeholder groups are also demonstrated to provide a better understanding of student expectations.

Methodology
Students of quality management courses were invited to collect those attributes that could have an impact on their perceived educational service quality. The compiled list of 23 characteristics has been formed on the basis of a four-point Likert scale-based questionnaire. With approximately 360 responses, thorough statistical analyses have been executed to investigate whether any significant differences could be detected between the quality attributes perceived by the different student segments. A group of lecturers has also been invited to fulfil the same questionnaire to compare their viewpoints with those of the students.

Findings
The results allow us to identify critical quality attributes which may be used in all platforms and interactions with students. The conclusions can be implemented on the course level to adjust the plan-do-check-act-based improvement of courses in which lecturers are directly interested.

Originality
As the new generation of students increasingly regard themselves as customers, they have become more aware of how they are taught and how they participate in the learning process. Institutionalizing this approach may contribute to the shaping of the organizational quality culture by emphasizing student focus and may result in the identification of best practices and standardization of processes at the course level.
Financial internationalization of emerging country multinationals: evidence from India
Authors: Jamaleh Mariam , Shukla Abha 
Published: July 2021

Purpose
Financial internationalization is of particular importance to emerging country firms. Its significance arises from the impact of institutional void and related agency problems (common to emerging markets) on the internationalization path of these firms. Building on concepts from international finance, agency theory and institutional theory, this paper aims to examine the main aspects of financial internationalization by emerging country multinationals, namely, cross-listing, foreign ownership and foreign independent directors.

Design/methodology/approach
This paper follows a multiple case study approach which is a good fit for the exploratory nature of this research. The interest is to examine the context-driven financial internationalization of each case firm and replicate the firm-level information to find a common strategy.

Findings
The findings suggest that financial internationalization by emerging country multinationals starts mainly as these firms plan to enter advanced country markets. It is a dynamic process that entails interaction between financial internationalization and real internationalization, as well as among different aspects of financial internationalization. Cross-listing comprises the first stage of the process. Then, foreign ownership, particularly foreign institutional investments, would increase gradually in response to advances in financial and factor markets. Recruiting foreign independent directors seems to be adopted last, possibly out of fear of losing control of strategic decisions.

Originality/value
This paper presents a unique perspective that delineates different stages of the process of financial internationalization by emerging country multinationals. This complements the efforts to explain the distinct path of internationalization followed by these firms and supplements scarce literature by including emerging multinationals from India where the matter has not yet attracted proper attention.
Significant sensors and parameters in assessment of dysarthric speech
Authors: M. Dhanalakshmi , T. Nagarajan , P. Vijayalakshmi 
Published: July 2021

Purpose
Dysarthria is a neuromotor speech disorder caused by neuromuscular disturbances that affect one or more articulators resulting in unintelligible speech. Though inter-phoneme articulatory variations are well captured by formant frequency-based acoustic features, these variations are expected to be much higher for dysarthric speakers than normal. These substantial variations can be well captured by placing sensors in appropriate articulatory position. This study focuses to determine a set of articulatory sensors and parameters in order to assess articulatory dysfunctions in dysarthric speech.

Design/methodology/approach
The current work aims to determine significant sensors and parameters associated using motion path and correlation analyzes on the TORGO database of dysarthric speech. Among eight informative sensor channels and six parameters per channel in positional data, the sensors such as tongue middle, back and tip, lower and upper lips and parameters (y, z, φ) are found to contribute significantly toward capturing the articulatory information. Acoustic and positional data analyzes are performed to validate these identified significant sensors. Furthermore, a convolutional neural network-based classifier is developed for both phone-and word-level classification of dysarthric speech using acoustic and positional data.

Findings
The average phone error rate is observed to be lower, up to 15.54% for positional data when compared with acoustic-only data. Further, word-level classification using a combination of both acoustic and positional information is performed to study that the positional data acquired using significant sensors will boost the performance of classification even for severe dysarthric speakers.

Originality/value
The proposed work shows that the significant sensors and parameters can be used to assess dysfunctions in dysarthric speech effectively. The articulatory sensor data helps in better assessment than the acoustic data even for severe dysarthric speakers.
Tourists’ perceptions of urban space: a computer vision approach
Authors: Zhang Kun , Zhang Jinyi , Li Chunlin , Jiao Yan , Wang Ying 
Published: July 2021

Purpose
This study aims to conduct an empirical investigation of differing perceptions of nine types of urban space and nine visual elements among tourists in destination using a computer vision (CV) approach.

Design/methodology/approach
The data for this study was extracted from YFCC 100 M dataset. Nine types of urban space in Beijing were initially identified using a scene recognition model. Subsequently, a semantic segmentation model was applied, which yielded substantial evidence relating to nine visual elements that were used to elicit differing perceptions among tourists from different continents.

Findings
Tourists from three continents had different perceptions about corridors, old buildings, overlooks and traffic spaces, reflecting their cultural convention. Asians, Europeans and North Americans diversely gazed at the landscape element of buildings, foliage, sky and people in urban space. All those provided evidence to contribute to the tourist gaze theory's construction.

Originality/value
This study firstly depicted how tourists perceive the tourism symbol of urban space. The novel approach of employing two CV models offer methodological insights to tourism research relevant to visual perception.
Zorba the Greek’s tourism worldmaking: gendering Cretan place identity and Greek memory through film
Authors: Tzanelli Rodanthi , Koutoulas Dimitris 
Published: July 2021

Purpose
Drawing on the discursive properties of placemaking theory, this paper discusses the development of film tourism in Crete from the release of the award-winning Zorba the Greek (dir. Michael Cacoyannis, ZG) to date. The approach is “genealogical,” seeking to explain how ZG-inspired tourism on Crete ended up being more than about the film itself owing to historical contingency.
Multiple‐model stock assessment frameworks for precautionary management and conservation on fishery‐targeted coastal dolphin populations off Japan
Authors: Kanaji Yu , Maeda Hikari , Okamura Hiroshi , Punt André E. , Branch Trevor 
Published: July 2021

Abstract

Stock assessment approaches are often oversimplified due to lack of biological knowledge and insufficient data. In spite of world‐wide attention, fishery‐targeted coastal dolphin species in Japan have lacked in‐depth quantitative stock assessments because of limited time series of population size and an absence of associated biological information. We consequently developed integrated population models that analysed multiple sources of data simultaneously with published biological information within a Bayesian framework.

We estimate population status and trends for three main species targeted by fisheries, bottlenose dolphins Tursiops truncatus, Risso's dolphins Grampus griseu, and short‐finned pilot whales Globicephala macrorhynchus, using single‐species age‐aggregated and age‐structured population dynamics models. Models were fit to absolute abundance estimates from systematic line‐transect surveys, four series of abundance indices calculated from fisher's logbooks, and historical catch records. Published biological information was used to develop prior distributions for the biological parameters. We assessed the possible effects of ecological disturbance and competition using state‐space and multispecies models.

The multispecies model was selected by the model selection both for the age‐aggregated and the age‐structured approaches.

Single‐species assessments found that population size declined 4.2% (Risso's dolphin) to 8.0% (bottlenose dolphin) for three species since the late 1800s based on median posterior values, while the state‐space and multispecies models found that environmental disturbance and an interaction among species could have reduced population size more substantially.

Policy implications. Simple single‐species models are often used to provide conservation and management advice for wild animals but, in this case, results from such models are overly optimistic because they overlook important ecological process. In contrast, current population status could be less favorable if environmental disturbance and interspecific competition actually control population dynamics. Even if that is not the case, considering ecological process in the model will provide more precautionary ways. Our approach of combining multiple modelling frameworks is applicable to many other management systems, and offers increased confidence in estimated status and trends over assessments that consider only a single model.
Long‐term cross‐scale comparison of grazing and mowing on plant diversity and community composition in a salt‐marsh system
Authors: Chen Qingqing , Bakker Jan P. , Alberti Juan , Bakker Elisabeth S. , Smit Christian , Olff Han 
Published: July 2021

Abstract

Land abandonment has been increasing in recent decades in Europe, usually accompanied by biodiversity decline. Whether livestock grazing and mowing can safeguard biodiversity across spatial scales in the long term is unclear.

Using a 48‐year experiment in a salt marsh, we compared land abandonment (without grazing and mowing) and seven management regimes including cattle grazing, early season mowing, late season mowing, both early and late season mowing, and grazing plus each of the mowing regimes on plant diversity at the local and larger scales (i.e. aggregated local communities). Also, we compared their effects on community composition (both in identities and abundances) in time and space.

Under land abandonment, plant diversity declined in the local communities and this decline became more apparent at the larger scale, particularly for graminoids and halophytes. All management regimes, except for late season mowing, maintained plant diversity at these scales.

Local plant communities under all treatments underwent different successional trajectories, in the end, diverged from their initial state except for that under grazing (a cyclic succession). Year‐to‐year changes in local community composition remained at a similar level over time under land abandonment and grazing plus early season mowing while it changed under other treatments. Vegetation homogenized at the larger scale over time under land abandonment while vegetation remained heterogeneous under all management regimes.

Synthesis. Our experiment suggests that late season mowing may not be sustainable to conserve plant diversity in salt marshes. Other management regimes can maintain plant diversity across spatial scales and vegetation heterogeneity at the larger scale in the long term, but local community composition may change over time.

AbstractCadmium (Cd) is a widespread heavy metal pollutant in the environment that damages human health. In this study, the bioaccessibility and bioavailability of Cd in different Cd‐contaminated rice (low pollution level cadmium rice (Rice‐L, 0.111 mg/kg), medium pollution level cadmium rice (Rice‐M, 0.400 mg/kg), and high pollution level cadmium rice (Rice‐H, 0.655 mg/kg)) were estimated and determined by an in vitro digestion model Rijksinstituut voor volksgezondheiden milieu (RIVM), Caco‐2 cell model, and mouse model. The results indicated that Cd in the oral cavity (15.65–28.28%) displayed the lowest bioaccessibility comparing with small intestine (90.04–94.73%) and the stomach (99.30–100.70%) in vitro after cooking. In addition, the results showed that the bioaccessibility of Cd in CdCl2, CdCl2+normal rice (Rice‐N), Rice‐H, Rice‐M, Rice‐L group were 99.29%, 92.57%, 90.04%, 94.73%, and 91.11%, respectively; the in vitro bioavailability of Cd in CdCl2, CdCl2+Rice‐N, Rice‐H, Rice‐M, and Rice‐L group were 27.50%, 20.78%, 21.90%, 26.90%, 36.46%, respectively, we found that the group of CdCl2 is significantly higher than CdCl2+Rice‐N and Rice‐H (p < 0.05), while the targets hazard quotient (THQ) value of rice ingested without considering the in vitro bioavailability is 2.7–4.6 times than the THQ value with considered and the relative bioavailability (RBA) of Cd in Rice‐L, Rice‐M, Rice‐H are 80.25%, 64.32%, and 60.91%, respectively. These results indicate that the rice substrate has impact on the bioaccessibility and bioavailability of Cd, and might overestimate the health risks of Cd if bioavailability was not considered.Practical ApplicationStudying the bioaccessibility and bioavailability of cadmium in rice is a promising strategy to obtain a more accurate human health risk assessment of cadmium exposure in rice, as well as provide a theoretical basis for the formulation of cadmium limit standard in grain, which was also conducive to the rational and full utilization of rice resources in China.

SummaryImpaired wound closure is an increasingly crucial clinical challenge. Recently, wound healing has shifted towards innovative treatments that exploit nanotechnology, biomaterials, biologics and phototherapy. Here, we constructed an engineered MG1363‐pMG36e‐mCXCL12 strain with pMG36e plasmid encoding stromal cell‐derived factor 1α (named CXCL12) and evaluated the synergistic effects of light‐emitting diode (LED) yellow light and MG1363‐pMG36e‐mCXCL12 on scald wounds in mice. The results indicated that the combined treatment with LED yellow light with mCXCL12 delivering strain accelerated wound closure, tissue remodelling, re‐epithelialization and hair follicle regeneration and inhibited over‐inflammation oppositely in the central and surrounding wounds by macroscopic, histopathologic and immunohistochemistry parameters. Furthermore, combination therapy increased the epidermal growth factor and Ki67‐positive cells and upregulated beta‐catenin (β‐catenin), cellular‐myelocytomatosis (c‐Myc), wingless‐type MMTV integration site family member 1 (Wnt1), Jagged 1, neurogenic locus notch homolog protein 1 (Notch 1) and hairy and enhancer of split 1 (Hes 1) protein levels of the Wnt and Notch signalling pathways. It also facilitated collagen fibrogenesis and deposition and improved the activities of hydroxyproline, superoxide dismutase and glutathione peroxidase in scalded granulation tissue, in addition to reducing the inflammatory factors interleukin 1 beta (IL‐1β) and tumour necrosis factor alpha (TNF‐α). The combined treatment effectively reduced skin pathogens Ralstonia and Acinetobacter to further reduce the risk of infection. Overall, combination of LED yellow light and MG1363‐pMG36e‐mCXCL12 represents a potential strategy for the treatment of cutaneous wounds.
