Let X⊂ℙr be an integral and non-degenerate complex variety. For any q∈ℙr let rX(q) be its X-rank and S(X,q) the set of all finite subsets of X such that |S|=rX(q) and q   ∈  〈S〉, where 〈〉 denotes the linear span. We consider the case |S(X,q)|>1 (i.e. when q is not X -identifiable) and study the set W(X)q:=∩ S∈S(X,q)〈S〉, which we call the non-uniqueness set of q. We study the case dimX=1 and the case X a Veronese embedding of ℙn. We conclude the paper with a few remarks concerning this problem over the reals.

The author studies forms over finite fields obtained as the determinant of Hermitian matrices and use these determinatal forms to define and study the base polynomial of a square matrix over a finite field.

The authors give full proofs for the new results, quoting previous works by other authors in the proofs. In the introduction, the authors quoted related references.

The authors get a few theorems, mainly describing some monic polynomial arising as a base polynomial of a square matrix.

As far as the author knows, all the results are new, and the approach is also new.

Paragliding festivals have become significant events in the global tourism space, attracting tourists to local and international destinations. The purpose of this study was to assess environmental attitudes and rate the performance of the paragliding festival of the Kwahu traditional area in Ghana, from the perspectives of four stakeholder groups.

This study was grounded on the salient stakeholder theory. A quantitative cross-sectional study, with a convenience sampling approach, collected 372 useable questionnaires from four major stakeholders/participants (i.e. Kwahu residents, Kwahu returnees, non-Kwahu Ghanaian tourists and foreigners). Analysis of variance (ANOVA) was used to analyse the data.

The findings of the Games-Howell post-hoc test show no significant differences among the four stakeholder groups in the festival performance assessment. However, there is a significant statistical difference between the Kwahu residents and foreign tourists regarding environmental attitudes towards the paragliding festival.

Visitors' perceptions and experiences of the environmental performance could inform the planning and execution of festive events that have a direct impact on the natural environment. Policymakers at the community levels must enact environmental protocols that uphold the value propositions of the stakeholders and that of the community at large.

The study expands the application of the salience stakeholder model within festival tourism by highlighting under-represented stakeholder voices in a single study on paragliding festivals in a developing country context.

The coronavirus disease 2019 (COVID-19) pandemic has once again brought to our attention one of the three main pillars of sustainability–the environment. It has also brought into sharp relief the fragility of the live music festival sector, whose success hinges fundamentally on the capacity for both travel and mass gatherings to occur. Considering this intersection of environmental sustainability and the live music festival sector, this paper–which reports on events occurring long before the global pandemic took hold–examines the ways in which eight Australian folk and world music festivals successfully engage in eco-friendly and pro-environmental practices and educational activities at their events. Findings from this research will assist industry practitioners in being able to engage in similar practices at their events, as well as further academic understandings of the relationship between the environment and the live music sector, and the role of environmental communication practices within this.

This study engaged an exploratory research design using interviews to gain an insight into the perceptions of eight live music festival promoters regarding their patrons' on-site eco-friendly behaviours and engagement with the eco-friendly initiatives at their events.

Social support within the on-site festival community (applied here through the notion of a sense of communitas), coupled with the provision of eco-friendly initiatives and effective environmental communication approaches, were key pivot drivers to support patrons' pro-environmental behaviours. Engagement with environmental authorities and experts during the festivals was found to validate their eco-friendly approaches.

This paper provides details of, as well as insights into, the success of the eco-friendly and pro-environmental education practices engaged at select world and folk music festivals in Australia. It broadens and builds upon existing understandings of environmental communication practices.

This chapter is an examination of the contribution of female musicianship to the Perth metal scene, particularly in relation to the positioning of women in frontier mythology and the ways in which we might read the gothic sublime in terms of women’s experiences. While it has been recognised that Australian metal music, in general, is tied to the colonial frontier narrative, Perth’s isolation produces a particular kind of frontier narrative which can be read in relation to the gothic sublime. In this chapter, the author examines three Perth metal bands which comprise female members: Claim the Throne (featuring Jess Millea on keys and vocals), Sanzu (featuring Fatima Curley on bass) and Deadspace (featuring Shelby Jansen on bass and vocals). The author will argue that there is a motif running through Perth bands that comprise female musicians that is tied to their positioning in the Western frontier narrative and its production in relation to the gothic sublime. To do so presents one kind of way to conceptualise a metal scene on the ‘Western Front’. The author emphasises that this is not a totalising conceptualisation, rather, it is one way to suggest how context might shape women’s experiences and, perhaps more importantly for this argument, the way in which women women’s experiences and historicity in relation to the legacy of ‘frontierswomen’ inflect metal music in this scene.

In this study, the concept of career, which is one of the most significant functions of human resources, is examined. Toward the end of the twentieth century, restricted models, in which individuals work in a workplace in a classical manner, have been replaced by more flexible models. Due to certain reasons such as changing environmental conditions, increasing education levels, and the impact of employee’s values on his/her work life, individuals’ work life have been dramatically changed. Therefore, some career approaches oriented for these changing conditions and current requirements have been proposed by both academicians and professionals. These approaches mostly include removing workplace limits, offering the opportunity to work from anywhere, using various skills at different departments without any limitations. Basing on the aforementioned changes in theory and practice, this study investigates up-to-date career approaches in a holistic manner. In this context, the background and practicability of these theoretically framed approaches are also discussed in the present study

The consumption of music performed in different languages represents a significant aspect of the contemporary cultural experience. This phenomenon questions how different languages mediate music consumption in specific national contexts. In this paper, the authors investigate the case of live music consumption in France.

The authors surveyed 428 persons who saw 159 artists either performing in French or in English in 46 locations around Paris, France. The authors tested the effect of the language of the concert on three dimensions of music consumption: singing in unison, appraisal of the lyrics and dancing.

Multilevel analysis revealed that English was positively associated with dancing, whereas French was positively associated with the appraisal of the lyrics. The authors found no evidence that the language of the concert was associated with differences in singing in unison.

Results are discussed with respect to language diversity in the context of globalised popular music consumption.

The purpose of this paper is to explore and clarify the relationship between creative developments and the concepts of place and placemaking.

This paper systematically reviews scholarly literature on the relationship between creative developments and the concepts of place, and critically analyzes the extent to which creative developments acknowledge different aspects of place.

The findings demonstrate that the relationship between creative development and place is multifaceted, and combines physical, cultural and social aspects of place. However, the literature also calls for the greater valuation of particular facets of place, including the daily experiences of communities and local cultural producers, alongside symbolic and imagined aspects of place, all of which inform either positive or negative perceptions of urban form. In addition, the authors argue that the cultural value of the creative industries needs to be better acknowledged in creative developments, implying support for a range of cultural practitioners.

The authors argue that embracing a more holistic understanding of place in creative development has the potential to minimize the negative impacts sometimes associated with such developments (like gentrification and social displacement) while generating greater social and cultural benefits to people and place. The study findings raise questions that frame a critical research agenda for creative-led developments and creative placemaking in this context.

By examining the broader relationship between creative developments and place and identifying areas neglected by researchers, this research contributes to an articulation of “creative placemaking” that moves creative city policy toward enhancing community development.

The measurement of heat flux is of importance to the development of aerospace engine as basic physical quantities in extreme environment. Heat radiation is one of the basic forms of heat transfer phenomenon. The structure optimizing can improve the performance and infrared absorptivity of the thin film sensor.

This paper designed one kind of thin film heat flux sensor (HFS) with antireflective coating based on transparent conductive oxide thermopile. The introduced membrane structure is so thin that it has little impact on sensor performance. Fabrication of thin film sensors were fabricated by physical vapor deposition (PVD) process.

The steady-state and dynamic response characteristics of the HFS were investigated by calibration platform. The experimental results shown that the absorptivity of the membrane structure (for1070nm) improved compared with that before optimization. The sensitivity of heat flux gauge was 48.56 µV/ (kW/m2) and its frequency response was determined to be about 1980 Hz.

The thin film HFS uses thermopile based on Indium Tin Oxid and In2O3. The antireflective coating is introduced to hot endpoint of HFS to improve sensitivity on laser thermal source. The infrared optical properties of membrane layer structure were investigated. The steady-state and the transient response characteristics of the heat flux sensor were also investigated.
