Exploring Mass Message Customization

The paper begins with the exploratory concept of ‘mass customization’ and then moves on to discuss the possibility of applying it in business communication. Further, it gives a brief framework within which to fit this concept. The author then argues the relevance of the concept in today’s workplace. However, this paper does not discuss the details of the ‘process of mass message customization.’ It just hints to possible areas for further research and exploration.

Soft Factorization in QED from 2D Kac-Moody Symmetry

The soft factorization theorem for 4D abelian gauge theory states that the $\mathcal{S}$-matrix factorizes into soft and hard parts, with the universal soft part containing all soft and collinear poles. Similarly, correlation functions on the sphere in a 2D CFT with a $U(1)$ Kac-Moody current algebra factorize into current algebra and non-current algebra factors, with the current algebra factor fully determined by its pole structure. In this paper, we show that these 4D and 2D factorizations are mathematically the same phenomena. The soft `tHooft-Wilson lines and soft photons are realized as a complexified 2D current algebra on the celestial sphere at null infinity. The current algebra level is determined by the cusp anomalous dimension. The associated complex $U(1)$ boson lives on a torus whose modular parameter is $\tau =\frac {2\pi i }{e^2}+\frac{\theta}{ 2 \pi}$. The correlators of this 2D current algebra fully reproduce the known soft part of the 4D $\mathcal{S}$-matrix, as well as a conjectured generalization involving magnetic charges.Comment: 20 page

An Online Magazine for and by Children: A Quasi Experimental Study

The objective of the study was to help children conceptualise and develop an on-line magazine and observe changes in their skills and confidence as communicators due to their experience of developing this online magazine. A single group Post-test Post-test design was used for this study. A natural sample consisting of 23 students studying in standard six of Amrit Vidyalaya, Kalol, India was selected. The data collection was organized in three phases: Conducting the pre-tests, administering the treatment, conducting the post-tests. Paired samples t-tests were computed with the pre-test and the post-tests scores. Other statistics like measures of central tendency, correlation coefficients and range were computed for all the three tests. An evaluation questionnaire consisting of six questions was administered to 24 students of class sixth of Baroda High School, Alkapuri, Vadodara after the launch of the magazine on www.amritvidyalya.org website. The effect of the treatment has been positive in all the tests, however statistically only the Computer Test-1 showed significant change. Moreover, there is a direct indication from students’ writings that they have had an enriching learning experience and the treatment has had a positive impact on them.

Fluorescent in situ hybridization and flow cytometry as tools to evaluate the treatments for the control of slime-forming enterobacteria in paper mills

Slime formation is a serious problem nowadays in the paper industry. Some enterobacteria are associated with the formation of slime deposits in paper and board mills. Detection and characterization of slime forming bacteria, belonging to the genus Enterobacter, Raoultella, and Klebsiella have been achieved by fluorescence in situ hybridization (FISH), using one probe based on the enterobacterial repetitive intergenic consensus sequence and other two rRNA targeted oligonucleotide probes. The effects of three kinds of antimicrobiological products (biocides, dispersants, and enzymes) on these enterobacterial cells were analyzed by flow cytometry (FC). Biocides Butrol 1009 and 1072 were the most effective microbiocides against all enterobacterial cells analyzed, reaching 90% of dead bacteria after 24 h. However, the enzymatic treatment (Buzyme) was not equally efficient on enterobacteria and its microbiocide capacity varied depending on the type of microorganism. FISH and FC were effective tools to detect important slime forming enterobacteria and to select specific treatments to control microbial problems in the paper industry

Gene transfer in a newly established spontaneous feline fibrosarcoma cell line

Fibrosarcoma is a deadly disease in cats and is most often located at classical vaccine injections sites. More rare forms of spontaneous non-vaccination site (NSV) fibrosarcomas have been described and have been found associated to genetic alterations. Purpose of this study was to compare the efficacy of adenoviral gene therapy in NVS fibrosarcoma. The NVS fibrosarcoma cell line (Cocca-6A) was isolated from a spontaneous fibrosarcoma that occurred in a domestic calico cat. Cocca-6A fibrosarcoma cells were morphologically and cytogenetically characterized. The feline cells were karyotyped and their chromosome number was counted using a Giemsa staining. Giemsa block staining of metaphase spreads of the Cocca-6A cells demonstrated deletion of one of the E1 chromosomes, where feline p53 maps. Adenoviral gene therapy demonstrated a remarkable effect on the viability and growth of the Cocca-6A cells following transduction with adenoviruses carrying RB/p105, Ras-DN, Mda-7/IL-24 or their combination. Adenoviral gene transfer was verified by western blot analysis. Flow cytometry assay and Annexin-V were used to study cell-cycle changes and cell death of transduced cells. Therapy for feline fibrosarcomas is often insufficient for long lasting tumor eradication. The use of Ad.Ras-DN, Ad.Rb/p105 and Ad.Mda7/IL-24 has been identified as a gene therapy for a possible future adjuvant treatment in spontaneous feline fibrosarcoma. More gene therapy studies should be conducted in order to understand if these viral vectors could be applicable regardless the origin (spontaneous vs. vaccine induced) of feline fibrosarcomas

How South Africa's borrowed higher education policies alienate the Higher Certificate students and contribute to the creation of NEETs

A review of four South African policies reveals that the post-apartheid government harbours neoliberal values that promote competition in higher education and promote the use of English. Through a critical document analysis, the research aimed to ascertain if the use of only English in South African higher education policies lead to a reproduction of neoliberal policies that actively exclude higher certificate students in universities. This study found that the neoliberal values further disenfranchise vulnerable student groups exemplified by the higher certificate cohort in university contexts as the policies barely address their linguistic rights through quantifiable strategies. Instead, English is promoted as necessary in both education and employment. The state’s failure to reflect on linguistic access is most perilous for students who are already outcasted in universities and the neoliberal focus on bachelor's programmes within Science, Technology, Engineering and Mathematics condemns vulnerable students to possible NEET (Not in Employment, Education or Training) status. Robert Phillipson’s ideas on linguistic neoimperialism are used to situate this discussion. Ideas on disinvestment and disconnection are entertained as one of possible solutions to linguistic neoimperialism

Re-narrating and re-masculating the 'brute' in the first season of eKasi: our stories

A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Arts. Wits University, Johannesburg, 2015Hollywood has always paid much attention to black masculinity; depicting black males in ways that demean them to keep them as subordinates. This stereotypical representation of black men, especially in the townships, has been one that South African filmmakers have subscribed to with the constant portrayal of black men as ‘as animals, brutes, natural born rapists, and murderers’ (hooks 2004). A study of e.tv’s short film series, eKasi: Our Stories, will illustrate how this series typifies what Morrell refers to as ‘new masculinities’ and furthermore explores black masculinities as multitudinous as “there are many characteristics and experiences that define black men” (Whiting & Lewis 2008). The first season of the series, with five episodes will be critically studied to demonstrate how black masculinities have been reimaged by the filmmakers of these short films. These short films open up spaces for various identities for black men by affording the characters complexity. This will be showcased with a careful examination of the themes of these five stories. Also of equal importance is the characterisation of the black male characters in relation to others and their communities. The study focuses on how the revision of the black man from the township gives back to him the humanity, dignity and most notably masculinity which he had been stripped off since his first appearance on film and television. By employing Harris’ (2006) notion of a New Black Cinema, it will be demonstrated that the short film series is in line with emerging theories of the revision of the black image onscreen

MICROBIOLOGICAL ANALYSIS OF BOVINE COLOSTRUM AND ORGANOLEPTIC EVALUATION OF BOVINE COLOSTRUM RECIPES

Bovine colostrum, Bovine colostrum secreted by the cow’s udder is sterile but due to its high nutrient content, it can be good microbiological growth substrate for contaminating bacteria. The aim of this study was to conduct microbiological analysis analysis, sensory of fresh colostrum of cow, to use steamed colostrum of cowinstead of paneer in Indian recipes like burfi evaluation, burfi, and pakoda, to evaluate sensory quality of recipes and to calculate nutritive value of recipes. Microbial pakoda. contamination can commonly originate from inside the udder, external sources, and the surfaces of equipment used in the handling and storage of colostrum.Potential risks associated with microbial contamination of bovine colostrum include foodborne diseases, reduced immune system functions, transmission of infectious diseasesand decreased milk quality.For microbiological examination of cow colostrum, 15 samples of first day’s colostrum from the breed of Sahiwal were taken and stored in sterile bags. These mixed colostrum samples were analyzed for Streptococcus spp, Bacillus cereus, Staphylococcus aureus, Lactobacillus spp, and Salmonella spp using standard procedures. Also,total plate count, spore count, coliforms and yeast was analyzed. Bacteriology for colony-forming units per gram (cfu/g) of raw bovine colostrum samples showed the presence of Lactobacillus spp (2.3 x 103), Moulds Aspergillus (<10), Total plate count (3.2 x 104), aerobic spore count (2.5 x 101), anaerobic spore count (<10), thermophillic spore count (<10), mesophillic spore count (2.5 x 101), coliform (5.2 x 103) and yeast (<10). But Salmonella and Bacillus aureus were not detected in the samples. For development of recipes like burfi and pakoda, bovine colostrum was steamed and then it was incorporated. Control recipes were prepared using paneer which was replaced by steamed bovine colostrum in experimental recipes. Products were standardized for their evenness andpalatability examination was carried by six trained jurors in three trails. Nutritive value of recipes was determined. Food products designed using cow colostrum were approved for appearance, colour, doneness, texture, flavor and taste in comparison with control recipes at both 5% & 1% levels (p>0.05). Bovine colostrum burfi received the mean scores of 9.88 for appearance, 10 for colour, 9.55 for texture, 9.77 for mouthfeel, 9.88 for flavour, 10 for taste and 9.88 for acceptability. The mean scores obtained for bovine colostrum pakoda included 10 each for appearance, color, texture, mouthfeel, flavor and acceptability whereas the score was 9.77 for taste. Bovine colostrum burfi and pakoda were found energy dense (309 and 404 kcal/100 g, respectively). These two products were found to be high in protein (burfi-13.72 and pakoda-7.50 g/100 g) and fat (burfi-22.39 and pakoda-37.14 g/100 g). To prevent microbial contamination of bovine colostrum, it\u27s essential to maintain proper hygiene, careful handling, using sterile containers, washing hands thoroughly, and applying appropriate heat treatment

Investigation Of Ultrasound Targeted Microbubbles As A Therapeutic Gene Delivery System For Prostate Cancer

A major challenge for effective gene therapy is systemic delivery of viruses carrying therapeutic genes into affected tissue. The immunogenic nature of human adenoviruses (Ads) limits their use for intratumoral (IT) injection in gene therapy. Ads transfection is further hampered by the fluctuating presence of Coxsackie and Adenovirus Receptor (CAR) and integrins on the cells’ surface. To circumvent these limitations we developed a novel approach wherein Ads are encapsulated inside the shell of lyophilized, lipid-encapsulated, perfluorocarbon microbubbles (MBs)/ultrasound (US) contrast agents, which act as delivery vehicles for a sitespecific gene transfer system. We performed infection studies with Ad.GFP (Green Fluorescent Protein), Ad.mda-7 (melanoma differentiation associated gene 7) and CTV.mda-7 on human DU145 and mouse prostate cancer cells as well as observed enhanced GFP expression when Ad.GFP was delivered by MBs and US. Our results show that US breaks open the MB/Ads complexes by undergoing cavitation at the sonoporated site, which allows Ads to transfer their transgene only to the sonoporated region. Cavitation collapse of the MBs creates small shockwaves that increase cell permeability by forming temporary micropores on the cell surface bypassing the receptormediated dependence of Ads for transfection. Fetal bovine serum (FBS) containing complement did not allow the unprotected Ads to infect the cells; however, MBs complexed with Ad.GFP did infect DU145 and TRAMP-C2 cells in a FBS rich media. We studied MB assisted gene delivery of reporter (GFP) and therapeutic genes (p53, Rb, Rb2 (p130) and Mda-7/IL-24) into prostate cancer (PC) xenografted in immune-compromised athymic mice. The results demonstrated that MBs protect the host from unspecific viral immune response thus protecting the viral payload and allowing for intravenous (IV) injection rather than IT injection. Additionally, Ad gene transfer was enhanced at the targeted/sonoporated mice tumor xenografts. This research demonstrated mda-7’s efficacy in reducing primary (treated) and untreated tumors that simulated the presence of metastasis in athymic mice xenograft models bearing human PC cells. Bystander anti-tumor activity of mda-7, a secreted cytokine was noted for non-targeted tumors. Earlier in vitro studies on the combination of radiation and gene therapy (Ad.p53, Ad.Rb, and Ad.p130) demonstrated an increase in the percentage of cell death for DU145 cells. We also studied UTMD (ultrasound targeted microbubble destruction) gene therapy in combination with external beam radiation for radiation resistant PC. The results demonstrated an enhanced therapeutic benefit of tumor suppressor genes in radiation resistant PC. We also demonstrated an increase in the expression of tumor suppressor genes at the tumor site due to MBs and US. These findings highlight the potential therapeutic benefit of this novel image guided gene transfer technology alone or in combination with external beam radiation for prostate cancer patients with therapy resistant disease
