Correlating the fineness and residual gum content of degummed hemp fibres

It is well known residual gum exists in degummed or retted hemp fibres. Gum removal results in improvement in fibre fineness and the properties of the resultant hemp yarns. However, it is not known what correlation if any exists between the residual gum content in retted hemp fibres and the fibre fineness, described in terms of fibre width in this paper. This study examined the mean width and coefficient of variation (CV) of fibre width of seventeen chemically retted hemp samples with reference to residual gum content. The mean and CV of fibre width were obtained from an Optical fibre diameter analyser (OFDA 100). The linear regression analysis results show that the mean fibre width is directly proportional to the residual gum content. A slightly weaker linear correlation also exists between the coefficient of variation of fibre width and the residual gum content. The strong linear co-relation between the mean of fibre width and the residual gum content is a significant outcome, since testing for fibre width using the OFDA is a much simpler and quicker process than testing the residual gum content. Scanning Electron Microscopy (SEM) reinforces the OFDA findings. SEM micrographs show a flat ribbon like fibre cross-section hence the term “fibre width” is used instead of fibre diameter. Spectral differences in the untreated dry decorticated skin samples and chemically treated and subsequently carded samples indicate delignification. The peaks at 1370 cm⁻¹, 1325 cm⁻¹, 1733 cm⁻¹, and 1600 cm⁻¹ attributed to lignin in the untreated samples are missing from the spectra of the treated samples. The spectra of the treated samples are more amine-dominated with some of the OH character lost.

Intra-organisational marketing culture and market orientation: a case study of the implementation of the marketing concept in a public library

The measurement of both marketing culture and behaviour provides the opportunity to gain more insight into the overall market focus of organisations. This article seeks to determine the market orientation and marketing culture of all staff within organisations, to ascertain to what extent other members of an organisation support or create barriers to the successful implementation of the marketing concept. This paper will provide a brief overview of the existing literature in the field of market orientation and marketing culture. After detailing the research design and methodology, a summary developed from 11 focus group sessions - consisting of all staff in one public library service in Victoria, Australia - is presented. The findings indicate that while all areas within this organisation are committed to marketing, there are various interpretations of marketing and how it should be implemented. In addition, the research finds a number of factors that could be instrumental in the successful implementation of the marketing concept in public libraries.

User-generated content and the changing news cycle

Blogs represent a major development in media consumption and practice.  The Pew Center in the United States reported in mid-2005 that about eight million Americans had created blogs and 32 million read them.  That's equivalent to two-thirds the number of people who read a daily newspaper during a week, a challenging giguew in the context of dwindling circulations.  Blogs represent the start of the 'personal media' revolution, but are only the tip of a range of new media developments.  This paper describes the blog phenomenon and notes its arrival via a series of major new stories.  It suggests we are seeing the emergence of a new news cycle, as blogs and other internet-based media usurp broadcast's role in breaking news.  The paper describes a range of emerging digital journalism forms that make up the 'personal media' revolution.  These include blogs delivered via mobile phones (moblogs); video-based blogs (v-logs); newspapers' use of podcasting to deliver content; and wikis, or peer-generated online content. The media's reaction to this new form of content is described, and the other concludes by looking at the forces driving this new form of journalism.

Intra-organisational attitudes to marketing and the Implementation of the marketing concept in nonprofit organisations

This paper explores the market orientation and marketing culture of all staff within a nonprofit organisation to ascertain the extent to which members of the organisation support or create barriers to the implementation of the marketing concept. Of particular interest in this research is the role of nonprofit organisations, which are often thought of as having a production, rather than marketing focus. Consequently, there may be cultural and behavioural conflicts between, for example, marketing personnel and production personnel. This paper provides a brief overview of the existing literature in the field of market orientation and marketing culture. After detailing the general research design, a summary of the results of 11 initial focus groups, consisting of all staff in one nonprofit organisation, is presented. The findings indicate that while all areas within this organisation are committed to marketing, there are various interpretations of marketing and how it should be implemented.

Fat content of chips, quality of frying fat and deep-frying practices in New Zealand fast food outlets

Objectives: To collect baseline data on the fat content of hot chips, quality (degradation) of cooking fat, deep-frying practices and related attitudes in fast food outlets in New Zealand. To identify the key determinants of the fat content of chips and quality of cooking fat. Methods: A nationally representative sample of fast food outlets (n=150, response rate 80%) was surveyed between September 1998 and March 1999. Data collected included a questionnaire, observation of cooking practices and analysis of cooked chips and frying fat. Results: Only 8% of independent operators had formal training in deep frying practices compared with 93% of chain operators. There was a wide range of fat content of chips (5%-20%, mean 11.5%). The use of thinner chips, crinkle cut chips and lower fryer fat temperature were associated with higher chip fat content. Eighty-nine per cent of chain outlets used 6–10 mm chips compared with 83% of independent outlets that used chips ≥12 mm. A wide range of frying temperatures was recorded (136–233°C) with 58% of outlets frying outside the reference range (175–190°C). As indices of fat degradation, fat acid and polar compound values above the recommended levels occurred in 54% and 5% of outlets respectively. Operators seemed willing to learn more about best practice techniques, with lack of knowledge being the main barrier to change. Conclusions and implications: Deep frying practices could be improved through operator training and certification options. Even a small decrease in the mean fat content of chips would reduce the obesogenic impact of this popular food.

Global and targeted gene expression and protein content in skeletal muscle of young men following short-term creatine monohydrate supplementation

Creatine monohydrate (CrM) supplementation has been shown to increase fat-free mass and muscle power output possibly via cell swelling. Little is known about the cellular response to CrM. We investigated the effect of short-term CrM supplementation on global and targeted mRNA expression and protein content in human skeletal muscle. In a randomized, placebo-controlled, crossover, double-blind design, 12 young, healthy, nonobese men were supplemented with either a placebo (PL) or CrM (loading phase, 20 g/day x 3 days; maintenance phase, 5 g/day x 7 days) for 10 days. Following a 28-day washout period, subjects were put on the alternate supplementation for 10 days. Muscle biopsies of the vastus lateralis were obtained and were assessed for mRNA expression (cDNA microarrays + real-time PCR) and protein content (Kinetworks KPKS 1.0 Protein Kinase screen). CrM supplementation significantly increased fat-free mass, total body water, and body weight of the participants (P < 0.05). Also, CrM supplementation significantly upregulated (1.3- to 5.0-fold) the mRNA content of genes and protein content of kinases involved in osmosensing and signal transduction, cytoskeleton remodeling, protein and glycogen synthesis regulation, satellite cell proliferation and differentiation, DNA replication and repair, RNA transcription control, and cell survival. We are the first to report this large-scale gene expression in the skeletal muscle with short-term CrM supplementation, a response that suggests changes in cellular osmolarity.

COPD results in a reduction in UCP3 long mRNA and UCP3 protein content in types I and IIa skeletal muscle fibers.

Purpose: Findings recently have shown coupling protein-3 (UCP3) content to be decreased in the skeletal muscle of patients with chronic obstructive pulmonary disease (COPD). Uncoupling protein-3 mRNA exists as two isoforms: long (UCP3L) and short (UCP3S). The UCP3 protein is expressed the least in oxidative and the most in glycolytic muscle fibers. Levels of UCP3 have been associated positively with intramyocellular triglyceride (IMTG) contents in conditions of altered fatty acid metabolism. As a source for muscle free fatty acid metabolism, IMTG is decreased in COPD. The current study completely characterized all the parameters of UCP3 expression (ie, UCP3L and UCP3S mRNA expression in whole muscle samples) and UCP3 protein content as well as IMTG content in the different fiber types in patients with COPD and healthy control subjects.

Methods: Using real-time polymerase chain reaction, UCP3 gene expression was quantified. Skeletal muscle fiber type and UCP3 protein and IMTG content were measured using immunofluorescence and Oil red oil staining, respectively.

Results: The findings showed that UCP3L mRNA expression was 44% lower (P < .005) in the patients with COPD than in the control subjects, whereas the UCP3S mRNA content was similar in the two groups. As compared with control subjects, UCP3 protein content was decreased by 89% and 83% and the IMTG content by 64% and 54%, respectively, in types I and IIa fibers (P < .0167) of patients with COPD, whereas they were unchanged in IIx fibers.

Conclusions: The reduced UCP3 and IMTG content in the more oxidative fibers may be linked to the altered muscle fatty acid metabolism associated with COPD. Further studies are required to determine the exact role and clinical relevance of the reduced UCP3 content in patients with COPD.

Marketing across cultures : an investigation into place specific dimensions of service quality in sport

Abstract The purpose of this study was to identify place-specific dimensions of service quality in spectator sport settings and determine if the importance of these dimensions differed across cultures. The study was limited to the soccer industry and involved the collection of responses from identified soccer spectators to a range of items presented in a survey instrument. The survey was distributed to respondents face-to-face on a match day of the club they supported, or mailed to their home address. Responses were obtained from spectators from two clubs from Australia (n=277), one club from the USA (n=199), one club from the Netherlands (n=245) and one federation from Malaysia (n= 100). Based on the findings of a number of authors, six categories of potential place-specific dimensions of service quality in spectator sport settings were created and the research instrument contained a number of items that could be categorised under one of these headings. These categories were Home, Religion, Social facilitation, Sensory, Uncertainty of outcome, and Personal attention. In this thesis it was assumed that place-specific service quality issues are similar for sport spectators of different cultures, although differences in degree of importance of these dimensions (etic approach) were likely to emerge. In other words, although it was expected dimensions per country to be similar, differences in degree of importance of these dimensions were expected. Given the lack of confirmatory statistical evidence pertaining to the specific country samples, it was concluded that differences per country are likely to be more than just differences in degree. Both the overall structure and structures per country could not be confirmed, and hence the conclusion was drawn that differences in nature between the countries were present. In other words, what is a dimension of place-specific service quality in one country is not necessarily a dimension in another country. The results of a content analysis of ‘core component’ structures per country compared with a (full sample) core component structure delivered six components (referred to as place-specific dimensions of service quality) that were defined as Home, Hedonist, Religious follower, Safe atmosphere, Hospitality and Personal Attention. It was found that in most cases the cultural orientation of soccer spectators reflects the cultural orientation of the country as a whole as proposed by Hofstede (1991). However, in line with Huntington (1997), it was also argued that grouping people based on their country of origin as a proxy for their cultural orientation, will increasingly lead to flawed and incomplete research findings. As noted by Yoo etal. (1999), the identification of a person's cultural orientation is likely to deliver more direct results when measured at the individual level In that regard it is concluded that it may seem prudent to view Hofstede's dimensions of culture with increased conceptual scrutiny. Although having been replicated in multiple studies, it becomes increasingly unlikely that Hofstede's dimensions cover the complete spectrum of an individual person's cultural orientation. In conclusion, this study identified that soccer spectators (from a number of clubs) from Australia, the USA, the Netherlands and to a lesser extent Malaysia, perceive a range of place-specific service quality dimensions in spectator spoil settings to be important when visiting a soccer match. Before research into satisfaction with and value of place-specific dimensions of the spectator sport service product is initiated, it is pertinent the identified dimensions are further explored and confirmed in different country (culture) settings. The confusion that still exists about the place of the value concept (in relation to quality and satisfaction), where Holbrook (1994) defines quality as a type of value and Chelladurai and Chang (2000) argue that value is a type of quality, further underpins this necessity. It needs to be clear what are the targets of service quality before this information is integrated in larger holistic research frameworks. In the final section of the thesis a conceptual model for international services marketing research in the sport industry was presented as a first attempt to integrate the findings of this research and other researchers.

Arts management/marketing journal citation analysis : assessing external impact

Purpose – This paper aims to present a quantitative analysis of arts management/marketing articles in leading general management/marketing journals, including an examination of the extent to which those top tier journal articles on arts/culture-related topics cite authors of leading arts management journal articles.

Design/methodology/approach – Using bibliometric techniques, this study examines the content of 20 top tier management and marketing journals over 22 years to identify articles published on arts management/marketing, which authors were cited, and from which arts management/marketing journals.

Findings – Analysis indicates that: relatively few citations in the top management/marketing journals reference arts management/marketing journals; assessment of interaction between the parent management/marketing disciplines and the arts management/marketing sub-discipline indicates that authors draw upon a large reserve of diverse literatures; and top journal arts-related management/marketing articles tend to utilize citations to journal articles grounded in the social sciences and aesthetics of management, with an increasing trend of citations to arts management/marketing journals.

Research limitations/implications – This study of the extent to which top journals have published arts/culture-related articles and the citation impact of arts management/marketing journals is the initial academic study on the topic and suggests opportunities for further research.

Practical implications – Analysis of arts management/marketing journal impact contributes to professionalization of the field and increased perceived value of those journals by industry practitioners.

Originality/value – This research is the first to examine the spectrum of arts management/marketing literature, including both top general management/marketing journals and sector-oriented arts management/marketing journals, establishing a body of knowledge for augmentation by future research over time.

A content analysis of early childhood teachers’ theoretical and practical experiences with infants and toddlers in Australian teacher education programs

 In Australia, the growth in the provision of early childhood services for very young children aged birth to three years has placed increased demands on pre-service teachers as new policy stipulates the need for qualified early childhood teachers. While many teacher education programs offer early childhood courses, they have traditionally had a greater focus on kindergarten and the formal years of schooling. Less is known about the amount of time devoted to developing the specialist educational capacity for teaching and caring for infants and toddlers. This paper explores 55 Australian early childhood teacher undergraduate education programs to provide data regarding what pre-service teachers learn about children from birth to three years of age during their formal program of study. It explores: if pre-service teachers engage in practical experiences with this age range; what content they learn; and how knowledge for this age range is assessed. Utilising information from fully accessible public program websites, data in the form of course details were examined to reveal the extent and nature of courses inclusive of teaching and learning focusing on children aged from birth to three years. Of the 55 programs, 18 programs provided practical experience with infants and toddlers, and to a lesser extent content was evident and assessed. Most of the programs which included a focus on birth to three years of age were delivered by Victorian institutions. Findings are important for the future of early childhood teacher education in Australia and hold key messages for teacher registration bodies.

Combining collaborative and content-based filtering to recommend research papers

The number of research papers available today is growing at a staggering rate, generating a huge amount of information that people cannot keep up with. According to a tendency indicated by the United States’ National Science Foundation, more than 10 million new papers will be published in the next 20 years. Because most of these papers will be available on the Web, this research focus on exploring issues on recommending research papers to users, in order to directly lead users to papers of their interest. Recommender systems are used to recommend items to users among a huge stream of available items, according to users’ interests. This research focuses on the two most prevalent techniques to date, namely Content-Based Filtering and Collaborative Filtering. The first explores the text of the paper itself, recommending items similar in content to the ones the user has rated in the past. The second explores the citation web existing among papers. As these two techniques have complementary advantages, we explored hybrid approaches to recommending research papers. We created standalone and hybrid versions of algorithms and evaluated them through both offline experiments on a database of 102,295 papers, and an online experiment with 110 users. Our results show that the two techniques can be successfully combined to recommend papers. The coverage is also increased at the level of 100% in the hybrid algorithms. In addition, we found that different algorithms are more suitable for recommending different kinds of papers. Finally, we verified that users’ research experience influences the way users perceive recommendations. In parallel, we found that there are no significant differences in recommending papers for users from different countries. However, our results showed that users’ interacting with a research paper Recommender Systems are much happier when the interface is presented in the user’s native language, regardless the language that the papers are written. Therefore, an interface should be tailored to the user’s mother language.

Co-creation in hospitality industry: a case study on the drivers of traveler-generated content

User-generated content in travel industry is the phenomenon studied in this research, which aims to fill the literature gap on the drivers to write reviews on TripAdvisor. The object of study is relevant from a managerial standpoint since the motivators that drive users to co-create can shape strategies and be turned into external leverages that generate value for brands through content production. From an academic perspective, the goal is to enhance literature on the field, and fill a gap on adherence of local culture to UGC given industry structure specificities. The business’ impact of UGC is supported by the fact that it increases e-commerce conversion rates since research undertaken by Ye, Law, Gu and Chen (2009) states each 10% in traveler review ratings boosts online booking in more than 5%. The literature review builds a theoretical framework on required concepts to support the TripAdvisor case study methodology. Quantitative and qualitative data compound the methodological approach through literature review, desk research, executive interview, and user survey which are analyzed under factor and cluster analysis to group users with similar drivers towards UGC. Additionally, cultural and country-specific aspects impact user behavior. Since hospitality industry in Brazil is concentrated on long tail – 92% of hotels in Brazil are independent ones (Jones Lang LaSalle, 2015, p. 7) – and lesser known hotels take better advantage of reviews – according to Luca (2011) each one Yelp-star increase in rating, increases in 9% independent restaurant revenue whereas in chain restaurants the reviews have no effect – , this dissertation sought to understand UGC in the context of travelers from São Paulo (Brazil) and adopted the case of TripAdvisor to describe what are the incentives that drives user’s co-creation among targeted travelers. It has an outcome of 4 different clusters with different drivers for UGC that enables to design marketing strategies, and it also concludes there’s a big potential to convert current content consumers into producers, the remaining importance of friends and family referrals and the role played by incentives. Among the conclusions, this study lead us to an exploration of positive feedback and network effect concepts, a reinforcement of the UGC relevance for long tail hotels, the interdependence across content production, consumption and participation; and the role played by technology allied with behavioral analysis to take effective decisions. The adherence of UGC to hospitality industry, also outlines the formulation of the concept present in the dissertation title of “Traveler-Generated Content”.
