The effect of provocation in the form of mild erotica on attitude to the ad and corporate image: Differences between cause-related and product-based advertising

Provocative advertising is characterized by a deliberate attempt to gain attention through shock. This research investigates the reactions of individuals to a provocative appeal for a cause as opposed to a provocative advertisement for a standard consumer product, using mild erotica as the element of provocative imagery. An experiment using 391 adult subjects was conducted, and two analyses were performed. The first examined the effect of stimulus type (mildly erotic/nonerotic) by product category (cause appeal/consumer product) on attitude to the ad. The second examined the effect of stimulus type (mildly erotic/nonerotic) by cause (AIDS [acquired immunodeficiency syndrome]/SIDS [sudden infant death syndrome]) on corporate image. Both analyses also included gender as a third independent variable. The results suggest that people prefer mildly erotic ads generally, that an organization using mild erotica in appeals for a cause will be viewed more favorably where the erotica is congruent with the cause, and that women may be more responsive to mild erotica in cause appeals than are men.

Development of a long-life vacuum-packaged ready-to-eat meat product based on a traditional Portuguese seasoned meat

Carne do alguidar is a Portuguese traditional pork fried meat, usually manufactured for self-consumption purposes. This study developed a ready-to-eat (RTE) meat product, to meet today's consumers’ convenience, manufactured at the industrial scale evaluating its quality and shelf-life, assessing the effect of vacuum packaging and the use of an antioxidant (50 ppm BHT) to enhance oxidative stability. Physicochemical and microbiological parameters were assessed and a sensory analysis was performed. Interestingly, no significant differences were recorded between control (non-BHT) and antioxidant (BHT) samples. Microbiological counts remained at low levels throughout the storage period, ensuring the product’s required microbiological quality. At later storage stages, higher values of thiobarbituric acid reactive substances arose and off flavours and aromas were perceived. Still, overall appreciation was not affected until 12 months storage and a significant depreciation was perceived only after 15 months. Fibrousness and rising of off flavours were negatively correlated with overall appreciation.

Production responses of reproducing ewes to a by-product-based diet inoculated with the probiotic Bacillus amyloliquefaciens strain H57

The potential application of the spore-forming probiotic Bacillus amyloliquefaciens strain H57 (H57) as a novel probiotic for ruminants was evaluated in reproducing ewes. Performance responses were determined by delivering H57 in a pelleted diet based mainly on palm kernel meal (PKM) and sorghum grain. PKM is an agro-industrial by-product with a reputation for poor palatability and the availability of the starch in sorghum grain can be limited in ruminants. The hypothesis was that H57 improves the feeding value of a relatively low quality concentrate diet. Twenty-four first-parity white Dorper ewes were fed PKM-based pellets manufactured with or without H57 (109 cfu/kg pellet) in late pregnancy. During this phase of late pregnancy, the H57 ewes ate 17% more dry matter (1019 vs 874 g/day, P = 0.03), gained more weight (194 vs 30 g/day, P = 0.008) and retained more nitrogen (6.13 vs 3.34 g/day, P = 0.01), but produced lambs with a similar birthweight (4.1 vs 4.2 kg, P = 0.73). Rumen fluid collected from H57 ewes in late pregnancy had higher pH (7.1 vs 6.8, P = 0.07), acetate : propionate ratio (3.4 vs 2.7, P = 0.04), lower ammonia (69 vs 147 mmol/L, P = 0.001) and total volatile fatty acid concentrations (40 vs 61 mg/L, P = 0.02). The digestibility of dry matter, organic matter and fibre were similar between the two groups. The lambs of the H57 ewes grew faster than those of the Control ewes for the first 21 days of lactation (349 vs 272 g/day, P = 0.03), but not thereafter. H57 can improve feed intake and maternal liveweight gain in late pregnancy of first-parity ewes fed a diet based on PKM.

Adaptive project planning and management based on best practices - COBRA system

Planning a project with proper considerations of all necessary factors and managing a project to ensure its successful implementation will face a lot of challenges. Initial stage in planning a project for bidding a project is costly, time consuming and usually with poor accuracy on cost and effort predictions. On the other hand, detailed information for previous projects may be buried in piles of archived documents which can be increasingly difficult to learn from the previous experiences. Project portfolio has been brought into this field aiming to improve the information sharing and management among different projects. However, the amount of information that could be shared is still limited to generic information. This paper, we report a recently developed software system COBRA to automatically generate a project plan with effort estimation of time and cost based on data collected from previous completed projects. To maximise the data sharing and management among different projects, we proposed a method of using product based planning from PRINCE2 methodology.

Assessment of the Mutagenic Activity of Extracts of Brazilian Propolis in Topical Pharmaceutical Formulations on Mammalian Cells In Vitro and In Vivo

Propolis possesses various biological activities such as antibacterial, antifungal, anti-inflammatory, anesthetic and antioxidant properties. A topically applied product based on Brazilian green propolis was developed for the treatment of burns. For such substance to be used more safely in future clinical applications, the present study evaluated the mutagenic potential of topical formulations supplemented with green propolis extract (1.2, 2.4 and 3.6%) based on the analysis of chromosomal aberrations and of micronuclei. In the in vitro studies, 3-h pulse (G(1) phase of the cell cycle) and continuous (20 h) treatments were performed. In the in vivo assessment, the animals were injured on the back and then submitted to acute (24 h), subacute (7 days) and subchronic (30 days) treatments consisting of daily dermal applications of gels containing different concentrations of propolis. Similar frequencies of chromosomal aberrations were observed for cultures submitted to 3-h pulse and continuous treatment with gels containing different propolis concentrations and cultures not submitted to any treatment. However, in the continuous treatment cultures treated with the 3.6% propolis gel presented significantly lower mitotic indices than the negative control. No statistically significant differences in the frequencies of micronuclei were observed between animals treated with gels containing different concentrations of propolis and the negative control for the three treatment times. Under the present conditions, topical formulations containing different concentrations of green propolis used for the treatment of burns showed no mutagenic effect in either test system, but 3.6% propolis gel was found to be cytotoxic in the in vitro test.

Growth and yield of corn hybrids in response to association with Azospirillum brasilense and nitrogen fertilization

There is a growing interest in optimizing the positive effects of the association between Azospirillum bacteria and corn crop in order to reduce the use of nitrogen fertilizers. This study aimed to evaluate the inoculation efficiency of an A. brasilense-based commercial product in association with different rates of nitrogen fertilization in two corn genotypes. The experiment was arranged in a 2 x 2 x 5 factorial randomized block design, with four replications. The treatments consisted of two corn hybrids (30F53 and CD386); with and without inoculation with a commercial product based on A. brasilense and five nitrogen rates (0, 40, 80, 120 and 160 kg ha-1). The variables plant height, basal stem diameter, leaf area, shoot dry matter, leaf nitrogen content, length and diameter of the cob, weight of 100 grains and grain yield were evaluated. Inoculation with A. brasilense provided increases of 11 and 12% in leaf area and shoot dry matter, respectively. There were differences in the response of the corn hybrids for most variables and the increase in nitrogen supply provided increments in the growth and yield of corn.

The role of biomass and biorefineries in a sustainable future

Some o f the biggest issues facing humanity in the 21st century include energy security, global warming and resource scarcity. These issues will affect every nation and Ireland is no exception. There is much research underway to uncover technologies that will allow the world to overcome such problems, but none offer the flexibility o f biomass. Unlike other sustainable technologies, which offer a solution to one or at most two o f the above problems, biomass as demonstrated by the author, can play a part in mitigating all o f the above problems. It has been known for some time that biomass can be used in various ways as a form o f renewable energy, but with the development o f biorefineries biomass can be used to produce material as well as fuel products. In this report the author has looked at the viability and benefits o f biomass, bioenergy and biorefining in Ireland. The author has demonstrated that such technologies when implemented correctly are sustainable from an economic, environmental and societal point o f view. The author has shown in this thesis that abundant supplies o f biomass make bio re fineries a viable business opportunity in Ireland and has shown how a number o f biorefinery scenarios have the potential to be extremely profitable. The author has evaluated the profitability o f material product-based bio re fineries as well as fuel productbased configurations. The author demonstrated that value-added co-products help to make bio refineries profitable even when excise-relief is not granted on bio fuels. In this thesis the author has revealed some o f the problems that bioenergy and biorefineries have had to overcome to date and examines challenges that remain for bioenergy and biorefining, and looks at the future opportunities for bio fuels. This report concludes that biomass and biorefining has exciting business potential while offering unique opportunities to mitigate the problems o f the future.

Effect of Waterproofing Admixture Ipanex on Concrete Durability (includes Addendum), MLR-98-2, 1999

The concrete admixture Ipanex (Registered trademark) manufactured by IPA Systems Inc. was submitted to the Iowa Department of Transportation (Iowa DOT) New Products Committee on April 15, 1998. The New Products Committee requested that the Iowa DOT Materials Laboratory evaluate the durability, corrosion inhibiting and concrete permeability reduction effects of this admixture. This report is intended to present the results of testing in Iowa DOT materials laboratories, review a Pennsylvania State University report, as well as review the IPA Systems Inc. marketing literature. The objective is to provide the New Products Committee with a recommendation concerning approval of this product based on the information gathered. The portland cement concrete admixture Ipanex (Registered trademark) did not show any significant benefit in terms of improvement in areas of permeability, chloride resistance and strength in the testing performed at the Iowa DOT. The literature and reports reviewed did not provide enough credible evidence to refute this conclusion. Additionally, the benefits ascribed to this product can be more economically achieved using other currently available products such as slag and silica fume. The recommendation is that this product not be approved for use on State projects in Iowa.

Oliopohjaisen mallinnuksen käyttömahdollisuudet erään ohjelmistotuotteen eri kehitysvaiheissa

Oliopohjainen lähestymistapa on varsin uusi toimintaperiaate käytännön ohjelmistotuotantoprosesseissa. Oliopohjaisuus mahdollistaa nopean ja tehokkaan ohjelmistotuotannon sekä tuottaa uudelleenkäytettäviä luokkia. Tässä työssä tutkitaan oliopohjaisen mallinnuksen käyttömahdollisuuksia erään ohjelmistotuotteen kehityksessä ja keskitytään tuotteen määrittely- ja suunnitteluvaiheisiin. Tavoitteena on konkretisoida tarkastelun kohteena olevalle yritykselle oliopohjaisen mallinnuksen käyttötavat ja -mahdollisuudet osana yrityksen ohjelmistotuotantoprosessia. Työssä tarkastellaan yleisiä oliopohjaisen mallinnuksen toimintoja määrittely- ja suunnitteluvaiheissa. Erityisesti tarkastellaan yrityksen omaa ohjelmistotuotantoprosessia, TE Objectia, ja sen yhtymäkohtia yleisen oliopohjaisen mallinnuksen kanssa. Työssä kuvataan ohjelmistotuote, mallinnetaan ohjelmistotuotteen osa TE Objectia hyödyntäen ja pohditaan TE Objectin soveltuvuutta kyseisen tuotteen määrittelyyn ja suunnitteluun. Oliopohjaisen mallinnuksen todetaan sopivan hyvin tarkastellun tuotepohjaisen ohjelmiston kehitykseen. Tarkasteltavan tuotteen kehityksen pääpaino on uudelleenkäytettävyydellä, jota oliopohjainen mallintaminen erityisesti tukee. Kohdeyrityksen oman ohjelmistotuotantoprosessin, TE Objectin, todetaan vastaavan hyvin yleistä oliopohjaista mallinnusta määrittely- ja suunnitteluvaiheissa ja sitä suositellaan hyödynnettävän tarkastellun tuotteen määrittelyyn ja suunnitteluun soveltuvin osin. Työssä mallinnettiin kohdeyrityksen tuotteen osa esimerkinomaisesti, mikä konkretisoi TE Objectin käyttömahdollisuuksia osana yrityksen ohjelmistotuotantoprosessia.

Use of scenario analysis in studying emerging technology – Case Grid computing

Tutkimuksen selvitettiin miten skenaarioanalyysia voidaan käyttää uuden teknologian tutkimisessa. Työssä havaittiin, että skenaarioanalyysin soveltuvuuteen vaikuttaa eniten teknologisen muutoksen taso ja saatavilla olevan tiedon luonne. Skenaariomenetelmä soveltuu hyvin uusien teknologioiden tutkimukseen erityisesti radikaalien innovaatioiden kohdalla. Syynä tähän on niihin liittyvä suuri epävarmuus, kompleksisuus ja vallitsevan paradigman muuttuminen, joiden takia useat muut tulevaisuuden tutkimuksen menetelmät eivät ole tilanteessa käyttökelpoisia. Työn empiirisessä osiossa tutkittiin hilaverkkoteknologian tulevaisuutta skenaarioanalyysin avulla. Hilaverkot nähtiin mahdollisena disruptiivisena teknologiana, joka radikaalina innovaationa saattaa muuttaa tietokonelaskennan nykyisestä tuotepohjaisesta laskentakapasiteetin ostamisesta palvelupohjaiseksi. Tällä olisi suuri vaikutus koko nykyiseen ICT-toimialaan erityisesti tarvelaskennan hyödyntämisen ansiosta. Tutkimus tarkasteli kehitystä vuoteen 2010 asti. Teorian ja olemassa olevan tiedon perusteella muodostettiin vahvaan asiantuntijatietouteen nojautuen neljä mahdollista ympäristöskenaariota hilaverkoille. Skenaarioista huomattiin, että teknologian kaupallinen menestys on vielä monen haasteen takana. Erityisesti luottamus ja lisäarvon synnyttäminen nousivat tärkeimmiksi hilaverkkojen tulevaisuutta ohjaaviksi tekijöiksi.
