The Marketing Concept and BYOD in the University Classroom:

For decades marketing educators have espoused the marketing concept and consumer oriented business strategies in university classrooms. In recent years, there has been a movement away from the ‘sage on the stage’ to experiential, active learning pedagogies. Those newer pedagogies often involve the use of mobile devices, including smart phones, laptops, and e-readers as academic tools for students. While such mobile devices are nearly ubiquitous on college and university campuses, an ongoing debate revolves on the distinction between owning mobile devices and whether or not students bring them to campus and use them as educational tools. In this study, we surveyed students in order to assess their attitudes towards and perceptions of a proposed BYOD (Bring Your Own Device) program on campus

Destructive Selling: An Empirical View from the Perspective of University Level Business Students

Preliminary evidence indicates that salespeople working in a variety of industries hold the perception that destructive selling (defined as the intentional use of unethical tactics including lying, misrepresenting product/service performance, misleading the client, spreading rumors about the competition, etc. by professional salespeople) does occur in the professional selling discipline. A rich history of related research provides further evidence that university students exhibit negative perceptions and attitudes towards professional selling. In the work reported in this manuscript, the authors employed the survey research method to empirically study the perceptions held by university level pre-business and business students regarding the presence of destructive selling tactics in the world of professional selling. Results indicated that respondents believed that both B2B and B2C professional salespeople are intentionally engaging in destructive selling behaviors and tactics and that some firms are training their sales forces in the use of those tactics. Implications, limitations and future research avenues are presented

Rice bran arabinoxylan compound and quality of life of cancer patients (RBAC-QoL): Study protocol for a randomized pilot feasibility trial

© 2020 Introduction: Rice bran arabinoxylan compound (RBAC) is a nutraceutical for enhancing a depleted immune system during and after cancer treatment. This pilot feasibility trial aims to evaluate the effects of RBAC on cancer patients\u27 quality of life during active treatment, compared to placebo, using a validated questionnaire. Other outcome measures include changes in inflammatory and nutritional status, cytokine profile, and gut microbiota. Methods/Design: The study will recruit 50 participants from a regional cancer center in Australia. Patients aged 18–70, diagnosed with solid organ cancers stage II and above, and currently undergoing active systemic therapies, are eligible. Random allocation of participants into two groups is stratified based on metastatic status and treatment type. The dosage is either 3 g/day of RBAC or placebo in identical packaging. The participants, study coordinator, and treating oncologists are blinded to the interventions. Data collections are at baseline and at four follow-up sessions, which are six weeks apart (24 weeks). Statistical analysis will involve a protected p-value with multiple dependent values and analyzed by ANOVA with repeated measures on the occasion of testing and with both a full Bonferroni or Sidak corrections applied to protect against Type I errors. Any observed significance warrants further analysis with pairwise comparisons. Analysis of covariance will also be performed to assess any influence of the demographic data, cancer diagnosis, as well as changes in physical activity, dietary habits, and complementary medicine usage. Comparisons of gut microbiota will be based on the analysis of the fecal microbiome using 16S ribosomal ribonucleic acid amplicon sequencing. The proposed research timeline is from October 2018 to May 2022. Trial registration: ANZCTR. Reg No: ACTRN12619000562178p

Children With Cystic Fibrosis Are Infected With Multiple Subpopulations of Mycobacterium abscessus With Different Antimicrobial Resistance Profiles.

BACKGROUND: Children with cystic fibrosis (CF) can develop life-threatening infections of Mycobacterium abscessus. These present a significant clinical challenge, particularly when the strains involved are resistant to antibiotics. Recent evidence of within-patient subclones of M. abscessus in adults with CF suggests the possibility that within-patient diversity may be relevant for the treatment of pediatric CF patients. METHODS: We performed whole-genome sequencing (WGS) on 32 isolates of M. abscessus that were taken from multiple body sites of 2 patients with CF who were undergoing treatment at Great Ormond Street Hospital, United Kingdom, in 2015. RESULTS: We found evidence of extensive diversity within patients over time. A clustering analysis of single nucleotide variants revealed that each patient harbored multiple subpopulations, which were differentially abundant between sputum, lung samples, chest wounds, and pleural fluid. The sputum isolates did not reflect the overall within-patient diversity and did not allow for the detection of subclones with mutations previously associated with macrolide resistance (rrl 2058/2059). Some variants were present at intermediate frequencies before the lung transplants. The time of the transplants coincided with extensive variation, suggesting that this event is particularly disruptive for the microbial community, but the transplants did not clear the M. abscessus infections and both patients died as a result of these infections. CONCLUSIONS: Isolates of M. abscessus from sputum do not always reflect the entire diversity present within the patient, which can include subclones with differing antimicrobial resistance profiles. An awareness of this phenotypic variability, with the sampling of multiple body sites in conjunction with WGS, may be necessary to ensure the best treatment for this vulnerable patient group

A decade and a half of learning from Madagascar’s first locally managed marine area

While the participatory management of small scale fisheries has been widely promoted, we have limited understanding of the factors influencing its effectiveness. Here, we highlight lessons learnt from the implementation of Madagascar’s first locally managed marine area (LMMA), drawing on our insights and experiences as staff of a co-managing non-governmental organisation (NGO). We describe the LMMA’s context and history, and highlight aspects of our approach that we feel underpin its outcomes, including: i) co-management rather than community-management, ii) the permanent field presence of a supporting NGO, iii) a management focus on locally-important natural resources, iv) the implementation of poverty-alleviation initiatives aimed at reducing barriers to management, v) decision-making by resource users rather than scientists, vi) a diversified, entrepreneurial funding model, and vii) an emphasis on monitoring and adaptive management. We also highlight several challenges, including: i) the inability to influence fishery supply chains, ii) promoting participation and good governance, iii) promoting rule application, iv) standing up to outsiders, v) promoting environmental management in the long term, and vi) maintaining funding. Our experiences suggest that small scale fishers can be effective natural resource managers in low income contexts, but may need extended support from outsiders; however the role of supporting NGO is nuanced and complex

(Re)theorising laddish masculinities in higher education

In the context of renewed debates and interest in this area, this paper reframes the theoretical agenda around laddish masculinities in UK higher education, and similar masculinities overseas. These can be contextualised within consumerist neoliberal rationalities, the neoconservative backlash against feminism and other social justice movements, and the postfeminist belief that women are winning the ‘battle of the sexes’. Contemporary discussions of ‘lad culture’ have rightly centred sexism and men¹s violence against women: however, we need a more intersectional analysis. In the UK a key intersecting category is social class, and there is evidence that while working class articulations of laddism proceed from being dominated within alienating education systems, middle class and elite versions are a reaction to feeling dominated due to a loss of gender, class and race privilege. These are important differences, and we need to know more about the conditions which shape and produce particular performances of laddism, in interaction with masculinities articulated by other social groups. It is perhaps unhelpful, therefore, to collapse these social positions and identities under the banner of ‘lad culture’, as has been done in the past

Interaction between the microbiome and TP53 in human lung cancer.

BACKGROUND: Lung cancer is the leading cancer diagnosis worldwide and the number one cause of cancer deaths. Exposure to cigarette smoke, the primary risk factor in lung cancer, reduces epithelial barrier integrity and increases susceptibility to infections. Herein, we hypothesize that somatic mutations together with cigarette smoke generate a dysbiotic microbiota that is associated with lung carcinogenesis. Using lung tissue from 33 controls and 143 cancer cases, we conduct 16S ribosomal RNA (rRNA) bacterial gene sequencing, with RNA-sequencing data from lung cancer cases in The Cancer Genome Atlas serving as the validation cohort. RESULTS: Overall, we demonstrate a lower alpha diversity in normal lung as compared to non-tumor adjacent or tumor tissue. In squamous cell carcinoma specifically, a separate group of taxa are identified, in which Acidovorax is enriched in smokers. Acidovorax temporans is identified within tumor sections by fluorescent in situ hybridization and confirmed by two separate 16S rRNA strategies. Further, these taxa, including Acidovorax, exhibit higher abundance among the subset of squamous cell carcinoma cases with TP53 mutations, an association not seen in adenocarcinomas. CONCLUSIONS: The results of this comprehensive study show both microbiome-gene and microbiome-exposure interactions in squamous cell carcinoma lung cancer tissue. Specifically, tumors harboring TP53 mutations, which can impair epithelial function, have a unique bacterial consortium that is higher in relative abundance in smoking-associated tumors of this type. Given the significant need for clinical diagnostic tools in lung cancer, this study may provide novel biomarkers for early detection
