Interactive support effects on career agency and occupational engagement among young adults.

The PIC model by Gati and Asher describes three career decision making stages: pre-screening, in-depth exploration, and choice of career options. We consider the role that three different forms of support (general career support by parents, emotional/instrumental support, and informational support) may play for young adults in each of these three decision-making stages. The authors further propose that different forms of support may predict career agency and occupational engagement, which are important career decision precedents. In addition, we consider the role of personality traits and perceptions (decision-making window) on these two outcomes. Using an online survey sample (N = 281), we found that general career support was important for career agency and occupational engagement. However, it was the combination of higher general career support with either emotional/instrumental support or informational support that was found to lead to both greater career agency and higher occupational engagement. Personality also played a role: Greater proactivity also led to greater occupational engagement, even when there was little urgency for participants to make decisions (window of decision-making was wide open and not restricted). In practical terms, the findings suggest that the learning required in each of the three PIC processes (pre-screening, in-depth exploration, choice of career options may benefit when the learner has access to the three support measures.

Growing up in a mainstream world: a retrospective enquiry into the childhood experiences of young adults with a physical disability.

Children with disabilities are at greater risk of developing mental health problems than their peers, yet the emotional well-being of this group is largely overlooked and there is scant literature about children with a mobility disability. This study examined the retrospective experiences of growing up with mobility disability. The sample comprised of 16-25 year olds with mobility disability. A thematic analysis, informed by grounded theory was used. Themes identified included a common socio educational journey, conflict between care and independence in school and the impact of being singled out because of disability out side school. The result was a range of psycho-social issues that affected participants view of themselves and the world around them. The study also looked at what the participants found helpful in dealing with the emotional impact of their disability. Whilst some sought help through talking therapies, others found involvement in disability sport was helpful.

3'-UTR SIRF: A database for identifying clusters of short interspersed repeats in 3' untranslated regions

BACKGROUND:Short (~5 nucleotides) interspersed repeats regulate several aspects of post-transcriptional gene expression. Previously we developed an algorithm (REPFIND) that assigns P-values to all repeated motifs in a given nucleic acid sequence and reliably identifies clusters of short CAC-containing motifs required for mRNA localization in Xenopus oocytes.DESCRIPTION:In order to facilitate the identification of genes possessing clusters of repeats that regulate post-transcriptional aspects of gene expression in mammalian genes, we used REPFIND to create a database of all repeated motifs in the 3' untranslated regions (UTR) of genes from the Mammalian Gene Collection (MGC). The MGC database includes seven vertebrate species: human, cow, rat, mouse and three non-mammalian vertebrate species. A web-based application was developed to search this database of repeated motifs to generate species-specific lists of genes containing specific classes of repeats in their 3'-UTRs. This computational tool is called 3'-UTR SIRF (Short Interspersed Repeat Finder), and it reveals that hundreds of human genes contain an abundance of short CAC-rich and CAG-rich repeats in their 3'-UTRs that are similar to those found in mRNAs localized to the neurites of neurons. We tested four candidate mRNAs for localization in rat hippocampal neurons by in situ hybridization. Our results show that two candidate CAC-rich (Syntaxin 1B and Tubulin beta4) and two candidate CAG-rich (Sec61alpha and Syntaxin 1A) mRNAs are localized to distal neurites, whereas two control mRNAs lacking repeated motifs in their 3'-UTR remain primarily in the cell body.CONCLUSION:Computational data generated with 3'-UTR SIRF indicate that hundreds of mammalian genes have an abundance of short CA-containing motifs that may direct mRNA localization in neurons. In situ hybridization shows that four candidate mRNAs are localized to distal neurites of cultured hippocampal neurons. These data suggest that short CA-containing motifs may be part of a widely utilized genetic code that regulates mRNA localization in vertebrate cells. The use of 3'-UTR SIRF to search for new classes of motifs that regulate other aspects of gene expression should yield important information in future studies addressing cis-regulatory information located in 3'-UTRs.

Reading Between the Lines: The Potential of Popular Young Adult Fiction in Adolescent Spiritual Formation

Popular culture is a powerful, shaping force in the lives of teenagers between the ages of fourteen through eighteen in the United States today. This dissertation argues the importance of popular fiction for adolescent spiritual formation and it investigates that importance by exploring the significance of narrative for theology and moral formation. The dissertation employs mythic and archetypal criticism as a tool for informing the selection and critique of narratives for use in adolescent spiritual development and it also incorporates insights gained from developmental psychology to lay the groundwork for the development of a curriculum that uses young adult fiction in a program of spiritual formation for teenagers in a local church setting. The dissertation defends the power of narrative in Christian theology and concludes that narrative shapes the imagination in ways that alter perception and are important for the faith life of teenagers in particular. I go on to argue that not all narratives are created equal. In using literary myth criticism in concert with theology, I use the two disciplines’ different aims and methods to fully flesh out the potential of theologies intrinsic to works meant for a largely secular audience. The dissertation compares various works of young adult fiction (M.T. Anderson’s Feed and Terry Pratchett’s Nation in dialogue with a theology of creation; Marcus Zusak’s I am the Messenger and Jerry Spinelli’s Stargirl in dialogue with salvation and saviors; and the four novels of Stephanie Meyer’s Twilight saga in dialogue with a theology of hope (eschatology). The dissertation explores how each theme surfaces (even if only implicitly) from both literary and theological standpoints. The dissertation concludes with a sample four-week lesson plan that demonstrates one way the theological and literary critique can be formed into a practical curriculum for use in an adolescent spiritual development setting. Ultimately, this dissertation provides a framework for how practitioners of young adult formation can select, analyze, and develop materials for their teenagers using new works of popular young adult fiction. The dissertation comes to the conclusion that popular fiction contains a wealth of material that can challenge and shape young readers’ own emerging theology.

Discovering Clusters in Motion Time-Series Data

A new approach is proposed for clustering time-series data. The approach can be used to discover groupings of similar object motions that were observed in a video collection. A finite mixture of hidden Markov models (HMMs) is fitted to the motion data using the expectation-maximization (EM) framework. Previous approaches for HMM-based clustering employ a k-means formulation, where each sequence is assigned to only a single HMM. In contrast, the formulation presented in this paper allows each sequence to belong to more than a single HMM with some probability, and the hard decision about the sequence class membership can be deferred until a later time when such a decision is required. Experiments with simulated data demonstrate the benefit of using this EM-based approach when there is more "overlap" in the processes generating the data. Experiments with real data show the promising potential of HMM-based motion clustering in a number of applications.

Inferring Body Pose without Tracking Body Parts

A novel approach for estimating articulated body posture and motion from monocular video sequences is proposed. Human pose is defined as the instantaneous two dimensional configuration (i.e., the projection onto the image plane) of a single articulated body in terms of the position of a predetermined set of joints. First, statistical segmentation of the human bodies from the background is performed and low-level visual features are found given the segmented body shape. The goal is to be able to map these, generally low level, visual features to body configurations. The system estimates different mappings, each one with a specific cluster in the visual feature space. Given a set of body motion sequences for training, unsupervised clustering is obtained via the Expectation Maximation algorithm. Then, for each of the clusters, a function is estimated to build the mapping between low-level features to 3D pose. Currently this mapping is modeled by a neural network. Given new visual features, a mapping from each cluster is performed to yield a set of possible poses. From this set, the system selects the most likely pose given the learned probability distribution and the visual feature similarity between hypothesis and input. Performance of the proposed approach is characterized using a new set of known body postures, showing promising results.

Nano-urchin: The formation and structure of high-density spherical clusters of vanadium oxide nanotubes

We report the observation of urchin-like nanostructures consisting of high-density spherical nanotube radial arrays of vanadium oxide nanocomposite, successfully synthesized by a simple chemical route using an ethanolic solution of vanadium tri-isopropoxide and alkyl amine hexadecylamine for 7 days at 180oC. The results show that the growth process of the NanoUrchin occurs in stages, starting with a radial self-organized arrangement of lamina followed by the rolling of the lamina into nanotubes. The longest nanotubes are measured to be several micrometers in length with diameters of ~120 nm and hollow centers typically measured to be ~75 nm. The NanoUrchin have an estimated density of nanotubes of ~40 sr-1. The tube walls comprise layers of vanadium oxide with the organic surfactant intercalated between atomic layers. The interlayer distance is measured to be 2.9 ± 0.1 nm and electron diffraction identified the vanadate phase in the VOx nanocomposite as orthorhombic V2O5. These nanostructures may be used as three-dimensional composite materials and as supports for other materials.
