Meaning in the Process of Signification by the Advertisement of Honda
This study mainly deals with the process of signification in order to reveal how meaning is created by the advertisement of Honda HR-V 2014 through the use of expressions. In this study, “Meaning” is an integrated form consisting the three elements which are denotative form, connotative form, and myth form. Using qualitative content analysis (Schreier, 2012), the writer did this study based on Barthes's process of signification (1987) and Peirce's indexicality (1931-58). From the analysis, the writer found out that meaning is created by indexicality. The index connects the product and the traits that the product possesses. Then, the use of expressions in the advertisement visualises the index of the product. The index which was visualised by the use of expressions which produces denotative meaning and connotative meaning. Those denotative meaning and connotative meaning are perceived by the audiences and creates myth which naturalises the index itself. It can be concluded from this study that meaning is created by the index and has undergone several steps in order for audiences to perceive the myth and become unaware of the index
A unifying representation for a class of dependent random measures
We present a general construction for dependent random measures based on
thinning Poisson processes on an augmented space. The framework is not
restricted to dependent versions of a specific nonparametric model, but can be
applied to all models that can be represented using completely random measures.
Several existing dependent random measures can be seen as specific cases of
this framework. Interesting properties of the resulting measures are derived
and the efficacy of the framework is demonstrated by constructing a
covariate-dependent latent feature model and topic model that obtain superior
predictive performance
Incorporating project uncertainty in novel environmental biotechnologies: illustrated using phytoremediation
"Pollution of the environment by metals and organic contaminants is an intractable global problem, with cleanup costs running into billions of dollars using current engineering technologies. The availability of alternative, cheap and effective technologies would significantly improve the prospects of cleaning-up metal contaminated sites. Phytoremediation has been proposed as an economical and ‘green' method of exploiting plants to extract or degrade the contaminants in the soil. To date, the majority of phytoremediation efforts have been directed at leaping the biological, biochemical and agronomic hurdles to deliver a working technology, with scant attention to the economic outlook other than simple estimates of the cost advantages of phytoremediation over other techniques. In this paper we use a deterministic actuarial model to show that uncertainty in project success (the possibility that full clean up may not be realized) may significantly increase the perceived costs of remediation works for decision-makers."

Evaluating the Efficacy of an Attachment-Informed Psychotherapeutic Parenting Program for Incarcerated Parents
An attachment-based, psychotherapeutic parent education course was created for incarcerated mothers and fathers to improve their ability to provide positive parenting and a more stable home environment for their children. The current study assessed the effects of this parenting curriculum on parents’ tendencies to be abusive, their sense of efficacy and satisfaction as a parent, their psychological distress, and their knowledge of child development and positive child guidance strategies. Results of pre-post assessments showed a significant improvement in parents’ sense of efficacy and satisfaction in the parenting role; their knowledge, skills, and behavior as a parent; their understanding of child development; their knowledge of alternatives to using corporal punishment; establishing appropriate parent-child boundaries; and they were less likely to view their child’s independence as a threat. Females showed a significant decrease in distress symptoms. Results are discussed in terms of the critical need for effective, high-quality parent education to break the intergenerational cycle of poor parenting for this at-risk population
Statistical Mechanics of DNA-Mediated Colloidal Aggregation
We present a statistical mechanical model of aggregation in colloidal systems
with DNA mediated interactions. We obtain a general result for the two-particle
binding energy in terms of the hybridization free energy of DNA and
two model dependent properties: the average number of available DNA bridges
\left and the effective DNA conccentration . We calculate
these parameters for a particular DNA bridging scheme. The fraction of all the
-mers, including the infinite aggregate, are shown to be universal functions
of a single parameter directly related to the two-particle binding energy. We
explicitly take into account the partial ergodicity of the problem resulting
from the slow DNA binding-unbinding dynamics, and introduce the concept of
angular localization of DNA linkers. In this way, we obtain a direct link
between DNA thermodynamics and the global aggregation and melting properties in
DNA-colloidal systems. The results of the theory are shown to be in
quantitative agreement with two recent experiments with particles of micron and
nanometer size.

Modelling the hepatitis B vaccination programme in prisons
A vaccination programme offering hepatitis B (HBV) vaccine at reception into prison has been introduced into selected prisons in England and Wales. Over the coming years it is anticipated this vaccination programme will be extended. A model has been developed to assess the potential impact of the programme on the vaccination coverage of prisoners, ex-prisoners, and injecting drug users (IDUs). Under a range of coverage scenarios, the model predicts the change over time in the vaccination status of new entrants to prison, current prisoners and IDUs in the community. The model predicts that at baseline in 2012 57% of the IDU population will be vaccinated with up to 72% being vaccinated depending on the vaccination scenario implemented. These results are sensitive to the size of the IDU population in England and Wales and the average time served by an IDU during each prison visit. IDUs that do not receive HBV vaccine in the community are at increased risk from HBV infection. The HBV vaccination programme in prisons is an effective way of vaccinating this hard-to-reach population although vaccination coverage on prison reception must be increased to achieve this
