Development of Person-Person Network and Interacting PTTS in EpiSimdemicsMishra, Gaurav 23 May 2014 (has links)
Communications over social media, telephone, email, text etc have emerged as an integral part of modern society and they are popularly used for the expression of anger, anxiety, fear, agitation and opinion by the people. People's social interaction tend to increase dramatically during periods of epidemics, protest and calamities. Therefore, above mentioned communication channels plays an important role in the spread of infectious phenomenon, like rumors, fads and effects. These infectious phenomena alters people's behavior during disease epidemic [1][2].
Social contact networks and epidemics co-evolve [1][2]. The spread of a disease influences people's behavior which in turn changes their social contact network, thereby altering the disease spread itself. As a result, there is a need for modeling the spread of these infectious phenomena that lead to changes in behavior. Their propagation among population primarily depends on the social contact network. The nature of social contagion spread is very similar to the spread of any infectious disease as they are contagious in nature. To spread contagious disease requires direct exposure to an infectious agent, whereas social contagions can be spread using various communications media like social networking forums, phones, emails and tweets.
EpiSimdemics is an individual-based modeling environment. It uses a people-location bipartite graph as the underlying network [3]. In its current form, EpiSimdemics requires two people to interact at a location to model simulations. Thus, it cannot simulate the spread of social contagions that do not necessarily require the meeting of two agents at a location.
We enhance EpiSimdemics by incorporating Person-Person network, which can model communications between people that are not contact based such as communications over email, phone, text and tweet. This Person-Person network is used to model effects (social contagion) which induce behavioral changes in population and thus impacting the disease spread. The disease spread is modeled on Person-Location network. This leads to the scenario of two interacting networks: Person-Person network modeling social contagion and Person-Location modeling disease. Theoretically, there can be multiple such networks modeling various interacting phenomena.
We demonstrate the usefulness of this network by modeling and simulating two interacting PTTSs (probabilistic timed transition systems). To model disease epidemics, we have defined Disease Model and to model effects (social contagion), we have defined Fear Model. We show how these models influence each other by performing simulations on EpiSimdemics with interacting Disease and Fear Model. Therefore a model that does not include the affect adaptations on disease epidemics and vice-versa, fails to reflect the actual behavior of a society during disease epidemic spread. The addition of Person-Person network to EpiSimdemics will allow for a better understanding of the affect adaptions, which can include behavior changes in society during an epidemic outbreak. This would lead to effective interventions and help to better understand the dynamics of disease epidemic. / Master of Science

Previous issue date: 2017-03-29 / This paper analyzes the Housing Policy in Brazil, in particular Social Interest Housing,
focusing on the My House My Life Entities Program in the city of Goiânia from 2009 to
2015. How was the work of the social worker performed in the Technical Work Projects
(PTTS) of the Harmonia, Jardim Botânico I and Eldorado Oeste IV Housing Settlements,
built by Associations attached to Movements of Housing Movements of the State of
Goiás. Families moving to their homes begin to face problems such as distance, lack of
Public equipment , security and others. The struggle of entities seeking to provide
decent housing for the homeless has been working according to the criteria required by
the Minha Casa Minha Vida - Entities Program (PMCMV-E) / Este trabalho analisa a Política de Habitação no Brasil em especial a Habitação de
Interesse Social, com foco no Programa Minha Casa Minha Vida Entidades na cidade

a Entidades dos Movimentos de Moradia do Estado de Goiás. As famílias ao mudarem
para suas casas,começam a enfrentar problemas como a distância, a falta de
equipamentos públicos, segurança e outros. A luta das entidades em busca de propiciar
moradia digna aos sem teto, tem trabalhado de acordo com os critérios exigidos pelo

Understanding Posttraumatic Stress and Academic Achievement: Exploring Attentional Control, Self-Efficacy, and Coping Among College StudentsCantrell, Ashley M 01 July 2016 (has links)
The present study examined differences in attentional control, attentional control self-efficacy, and coping as self-regulatory mechanisms among students with varying grade point averages (GPA) who experience posttraumatic stress symptoms (PTSS). Subjects included 58 college students from one large comprehensive university in the Mid-South who met the criteria for diagnosis of PTSS based on the Impact of Event Scale-Revised (IES-R). Three groups were created based on college GPA and graduation requirements at the university (at-risk for graduation, on-track for graduation, and ontrack for graduating with honors). Participants completed a survey that included demographics and measures of PTSS, attentional control, attentional control self-efficacy, and coping. A one-way between groups ANOVA revealed statistically significant differences in attentional control self-efficacy and avoidant coping between the Honors and At-Risk groups. The current study provides additional information and support that success for students with PTSS may be explained by their confidence in their abilities to control their attention and using less avoidant coping strategies. However, as a group, students with PTSS need strategies for increasing their attentional control, self-efficacy beliefs, and adaptive coping.

N-methyl-6-hydroxyquinolinium: an investigation into the spectroscopy and applications of excited-state proton transferSalvitti, Michael Anthony 11 July 2008 (has links)
N-methyl-6-hydroxyquinolinium (NM6HQ) is a powerful excited-state proton donor, exhibiting a huge pKa drop from 7.2 in the ground state to -7 in the excited state. The zwitterionic nature of the proton transfer product encourages intramolecular electron transfer away from the hydroxyl moiety to the distal ring, allowing for a large pKa jump in the excited state. This process is reversible, making the NM6HQ salts powerful transient superacids. We have investigated the excited-state proton transfer (ESPT) from NM6HQ salts to various basic solvents (alcohols, DMSO). A model has been developed that adequately describes the ion-dipole interactions in the ESPT geminate-recombination process. Our studies have shown that the counterion plays a large role in the ESPT. Likewise, initiation of cationic polymerization is controlled by the counterion. NM6HQ perfluoroalkylsulfonates appear to be the first molecules reported which are capable of initiating aliphatic epoxide polymerization at room temperature through a proton transfer mechanism.
