The Relationship Of Parent And Child Self-talk In A College Sample

Donnelly, Reesa 01 January 2005 (has links)
Research has demonstrated the importance of early social interactions in the development of self-talk. It does not appear, however, that existing research has examined the relationship between parents' self-talk and the self-talk that develops in their children. This study examined the relationship between self-talk in parents and their college-age children. Results revealed significant relationships between students' and parents' positive self-talk, but not negative self-talk. Marginal relationships were found for self-talk ratios (ratios of positive and negative self-talk). Maternal communication was found to mediate the relationship between students' and their mothers' positive self-talk. Different trends also were noted between genders. Finally, self-talk was related significantly to depression, anxiety, and self-esteem. Overall, results of this study emphasize the relationship between parents' and their children's positive self-talk and the importance of self-talk in psychological functioning. These findings lend promise to the possibility of modifying parents' self-talk and communication as a way to modify their children's self-talk and psychological functioning.

Impact of Thermal Effects and Other Material Properties on the Performance and Electro-Thermal Reliability of Resistive Random Access Memory Arrays

Chakraborty, Amrita 21 December 2023 (has links)
As the semiconductor industry grapples with escalating scaling challenges associated with the floating gate MOSFET, alternative memory technologies like Resistive Random Access Memory (ReRAM) are gaining prominence in the scientific community. Boasting a straightforward device structure, ease of fabrication, and compatibility with CMOS (Complementary Metal-oxide Semiconductor) Back-end of Line (BEOL), ReRAM stands as a leading candi- date for the next generation of non-volatile memory (NVM). ReRAM devices feature nanoionics-based filamentary switching, outperforming flash memory in terms of power consumption, scalability, retention, ON/OFF ratio, and endurance. Furthermore, integrating ReRAMs within the CMOS BEOL/low-k Cu interconnect system not only reduces latency between the connectivity constraints of logic and memory modules but also minimizes the chip footprint. However, investigations have revealed a significant concern surrounding ReRAMs—specifically, their electro-thermal reliability. This research provides evidence highlighting the critical influence of material properties, deposition effects, and thermal transport on the device's performance and reliability. Various material systems have undergone in this work scrutiny to comprehend the impact of intrinsic material properties such as thermal conductivity, specific heat capacity, thermal diffusivity, and deposition effects like surface roughness on the electroforming voltages of ReRAM devices. The reference device structure considered in this work is Cu/TaOx/Pt, which has been compared with alternative configurations involving metals like Ru and Co as potential substitutes for Pt. Additionally, a new vehicle has been introduced to quantify cell degradation resulting from thermal cross-talk in crossbar Resistive Random Access Memory (ReRAM) arrays. Furthermore, a novel methodology has been presented to predict cell degradation due to remote heating, taking into account the cell's location, the material properties of the device, and geometry of its electrodes. The experimental results presented in this study showcase filament rupture caused by remote heating, along with spontaneous filament restoration ensuing from the subsequent cooling of the ReRAM cell. / Doctor of Philosophy / As the demand for compact, high-speed logic-memory modules continues to surge, the diminishing silicon real estate in our gadgets poses a challenge in extending Moore's law to meet the scaling needs of the semiconductor device industry. To tackle this challenge, emerging memory technologies like Resistive Random Access Memory (ReRAM) are positioned as promising successors to flash memory. ReRAM devices offer distinct advantages over flash memory, showcasing superior power consumption, scalability, long retention, a high ON/OFF ratio, and good endurance. Their compatibility with current CMOS (Complementary Metal-oxide Semiconductor) technology facilitates seamless integration. However, a significant concern associated with ReRAMs is their electro-thermal reliability. This research delves into how material properties comprising a ReRAM device and fabrication factors, such as the surface roughness of the material, can impact the electrical and thermal reliability of a ReRAM cell. In this context, a novel methodology has been introduced to predict cell degradation within ReRAM crossbar arrays induced by thermal cross-talk, considering material properties and the geometry of the device. The new methodology has been thoroughly verified on manufactured ReRAM arrays with various composite electrodes. The study also presents experimental results demonstrating the rupture of cell filaments due to remote heating, along with instances of spontaneous filament restoration due to subsequent cooling.

"Vi vet inte vad vi tycker om en bok förrän vi pratat om den" : en systematisk litteraturstudie om boksamtal och dess effekt på läsförståelse / "We don’t know what we think about a book until we talk about it" : A systematic literature study about book talk and its effect on readingcomprehension

Gustafsson, Martin, Magnusson, Emil January 2023 (has links)
Syftet med denna systematiska litteraturstudie är att med hjälp av tidigare forskning undersöka vilken betydelse boksamtal har för elevers läsförståelse, vilken roll läraren har vid boksamtal, samt hur boksamtal utformas. Studiens resultat bygger på både facklitteratur och vetenskapliga artiklar som hämtats genom databassökningar och manuella sökningar. Resultatet visar att boksamtal är viktigt för att öka elevers läsförståelse, flera källor anger samtal som en väsentlig del för att underlätta elevers förståelse. Resultatet visar även att frågor som läraren använder sig av, är av betydelse vid utformningen av boksamtalen. Det är av vikt att läraren väljer ut relevanta och intresseväckande frågor som möjliggör utformningen. Slutligen visar resultatet att läraren spelar en viktig roll vid boksamtal, då i en roll som samtalsledare.

Similarity and Potential Relation Between Periimplantitis and Rheumatoid Arthritis on Transcriptomic Level: Results of a Bioinformatics Study

Li, Shiyi, Zhou, Changqing, Xu, Yongqian, Wang, Yujia, Li, Lijiao, Pelekos, George, Ziebolz, Dirk, Schmalz, Gerhard, Qin, Zeman 24 March 2023 (has links)
Background: This bioinformatics study aimed to reveal potential cross-talk genes, related pathways, and transcription factors between periimplantitis and rheumatoid arthritis (RA). Methods: The datasets GSE33774 (seven periimplantitis and eight control samples) and GSE106090 (six periimplantitis and six control samples) were included from the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO). A differential expression analysis (p < 0.05 and |logFC (fold change)| ≥ 1) and a functional enrichment analysis (p < 0.05) were performed. Based on this, a protein–protein interaction (PPI) network was constructed by Cytoscape. RA-related genes were extracted from DisGeNET database, and an overlap between periimplantitis-related genes and these RA-related genes was examined to identify potential cross-talk genes. Gene expression was merged between two datasets, and feature selection was performed by Recursive Feature Elimination (RFE) algorithm. For the feature selection cross-talk genes, support vector machine (SVM) models were constructed. The expression of these feature genes was determined from GSE93272 for RA. Finally, a network including cross-talk genes, related pathways, and transcription factors was constructed. Results: Periimplantitis datasets included 138 common differentially expressed genes (DEGs) including 101 up- and 37 downregulated DEGs. The PPI interwork of periimplantitis comprised 1,818 nodes and 2,517 edges. The RFE method selected six features, i.e., MERTK, CD14, MAPT, CCR1, C3AR1, and FCGR2B, which had the highest prediction. Out of these feature genes, CD14 and FCGR2B were most highly expressed in periimplantitis and RA. The final activated pathway–gene network contained 181 nodes and 360 edges. Nuclear factor (NF) kappa B signaling pathway and osteoclast differentiation were identified as potentially relevant pathways. Conclusions: This current study revealed FCGR2B and CD14 as the most relevant potential cross-talk genes between RA and periimplantitis, which suggests a similarity between RA and periimplantitis and can serve as a theoretical basis for future research.

Style over Substance? A Content Analysis of the Gendered Style of Political Pundits on the "Big Five"

Ancarrow, Megan Ashley 28 June 2016 (has links)
It is well known that males dominate politics, both in elected positions and in the media as political pundits (Melber, 2011). Is it the masculine style that is appealing to society? Do popular political pundits (male and female) emulate this masculine style in order to appeal to and persuade their audience? Through a content analysis of the rhetoric of six specified political pundits, it is hypothesized that both males and females are more likely to incorporate masculine styles of rhetoric, and those who display more masculine style traits will be more acceptable to the general audience leading to more airtime and appearances across networks. Through the analysis of the programs' 2013 transcripts, the communicative style of both male and female political pundits of the top five news programs from the big five networks will be studied: ABC's This Week with George Stephanopoulos, CBS's Face the Nation with Bob Schieffer, CNN's State of the Union with Candy Crowley, Fox News Sunday with Chris Wallace, and NBC's Meet the Press with Chuck Todd. / Master of Arts

Modulation of Neurotransmission by the GABAB Receptor

Kantamneni, Sriharsha 20 December 2016 (has links)
No / Most inhibitory signals are mediated via γ-aminobutyric acid (GABA) receptors whereas glutamate receptors mediate most excitatory signals (Trends Neurosci 14:515–519, 1991; Annu Rev Neurosci 17:31–108, 1994). Many factors influence the regulation of excitatory and inhibitory synaptic inputs on a given neuron. One important factor is the subtype of neurotransmitter receptor present not only at the correct location to receive the appropriate signals but also their abundance at synapses (Pharmacol Rev 51: 7–61, 1999; Cold Spring Harb Perspect Biol 3, 2011). GABAB receptors are G-protein-coupled receptors and different subunits dimerise to form a functional receptor. GABAB receptor subunits are widely expressed in the brain and by assembling different isoform combinations and accessory proteins they produce variety of physiological and pharmacological profiles in mediating both inhibitory and excitatory neurotransmission. This chapter will describe the understanding of the molecular mechanisms underlying GABAB receptor regulation of glutamate and GABAA receptors and how they modulate excitatory and inhibitory neurotransmission.
