Learning Management Systems are of utmost importance in our technological world for educating young minds in the courses they are passionate about. The recent pandemic has only shown us how utilizing an online platform for learning and integrating it within the classroom has become vital. Education is crucial because it provides us with the tools and knowledge to move through our careers and life. Moving forward from this arduous time, there will be a need for various learning tools that we can provide to students and use as educators. This project provides an understanding of learning management systems and provides an LMS web application. In developing this web platform, there were various steps involved, such as research, design, implementation, testing, and integration. With this application, students, teachers, and administration will create a dynamic and cohesive learning environment.
Rendering animations into 2D or 3D involves sequential proceeding of inputs. This causes operational bottleneck, resulting in expensive and lengthy inefficient processes. In this paper, an efficient Blender-based software for creating 3D animations from related sources is proposed. It introduces a horizontally scaled and concurrent rendering of multiple Blender-based projects. It runs in three modes that combine to accomplish its task: Master, Client, and Slave. A single Master instance exposes a web GUI to the user, maintains the master list of render job states, and controls Slave instances. Client instances are launched on demand to provide users with a GUI to submit render jobs to the Master instance. Slave instances run on rendering machines and will, in turn, launch subprocesses of Blender to render individual frames when instructed to by the Master instance. Test implementation of our solutions indicate improvements over vertical scaling (increasing the power of a single rendering machine) and greatly reduces the overall time taken to render a complex animation project.
Scientology’s public relations function is based on research and writing by L. Ron Hubbard, who studied public relations and drafted documents directing Church communication strategies. Hubbard annotated the textbook Effective Public Relations, which was reprinted for Church practitioners. Textual analysis shows Hubbard was particularly interested in redefining key concepts, emphasizing interpersonal communication strategies, and selectively adopting media relations strategies. The findings suggest that he used the annotations to appropriate the text and position himself as a communications expert. Evidence suggests Church communication practitioners continue to follow Hubbard’s recommendations.
While podcasting has been around for over a decade, this popular format is experiencing a resurgence. This phenomenon has led many educators to return to this medium and ask questions regarding the meaningful integration for teaching and learning. Podcasting lends itself to the idea of learning anywhere and at any time. The benefits of using audio, but specifically integrating podcasting, are well established in the literature. Student-created podcasts have been shown to improve reading, writing, and listening skills (Smythe and Neufeld 53:488–496, 2010) and promote student engagement and collaboration and lead to gains in literacy development (Morgan 91:71–73, 2015). Podcasts offer students opportunities to revisit classroom content and instruction while providing greater critical thinking opportunities (Shumack and Gilchrist 1:5–9, 2009). According to Vandenberg ((2):54, 2018), podcasting aids students in storytelling techniques that feature the importance of logical and coherent thinking. Additionally, incorporating either audio or video podcasts allows for a greater ability to personalize and accommodate learners (O’Bannon et al. 57:1885–1892, 2011). As educators begin to explore opportunities for podcasting within the classroom, this article presents three real-world case studies of implementation in various educational contexts: elementary, high school, and higher education. These cases provide insight into how these educators diversely implemented podcasting while minimizing challenges. Additionally, the authors offer a set of recommendations that can potentially guide the process towards successful implementation. Within this section, various technical tools and podcasting content are included to provide a practical starting point to jumpstart implementation.
Extant research consistently demonstrates that bicultural harmony (or the perception that one's two cultures are compatible) is linked to better psychological adjustment, whereas bicultural compartmentalization (or the perception of separation between one’s two cultures) is not. However, we question whether the compartmentalization-adjustment association is null for everyone, and specifically, whether high compartmentalization (i.e., low blendedness) is ever good for adjustment. To examine the boundary conditions of these previous findings, we proposed that dialectical thinking (or the tolerance for psychological contradictions) is a potential moderator of the compartmentalization-adjustment association. With data from 795 self-identified bicultural/multicultural individuals from a large U.S.-American university, we found a significant moderating effect of dialectical thinking on the compartmentalization-adjustment association, such that the null relationship between compartmentalization and adjustment was evident for only biculturals with low levels of dialectical thinking. Interestingly, for biculturals with high levels of dialectical thinking, compartmentalization significantly predicted higher psychological adjustment. In other words, for biculturals who tend to think dialectically, perceiving their cultural identities as more compartmentalized was linked to better psychological adjustment. These findings suggest that the association between compartmentalization and adjustment may depend on moderating factors, such as dialectical thinking. We discuss further theoretical implications and future possibilities in biculturalism research.
Our aim was to adapt and validate a Brazilian Portuguese version of the Twin Relationship Questionnaire developed by Fortuna et al. (2010) and validated by H. Segal and Knafo-Noam (2019) in Israel. The respondents were 862 Brazilian mothers of twins ( N = 1724 twins) with mean age of 35 years (SD = 6.1). The majority of the sample lived in the Southeast (61.8%) or in the South (24.5%) of Brazil. We conducted a Multilevel Confirmatory Factor Analysis with the pair of twins as second level variable, and the five-factor structure (closeness, dependence, conflict, dominance, and rivalry) proposed by the original validation study of H. Segal and Knafo-Noam (2019) was confirmed. The final model retained 15 items out of 22 proposed in the original version of the questionnaire. Although the TRQ-BR has fewer items, the accuracy compared to the original questionnaire was maintained. Mixed Model Analysis (LMM) of TRQ scores were used to investigate twins’ relationships as a function of zygosity, age groups, and sex in order to provide evidence of convergent validity of the instrument. As expected, mothers perceived monozygotic twins (MZ) as more depedent than dizygotic twins (DZ). Furthermore, male twin pairs were considered more conflictive when compared to female twins. The present study showed that TRQ-BR is an adequate instrument for research purposes in the Brazilian population. It can also be useful for applied areas such as clinical and educational fields.
Background: Past evidence suggests obesity co-occurs with tobacco/nicotine, cannabis, and alcohol use in young adulthood, but whether this relationship extends to nicotine or cannabis vaping is unclear. Furthermore, differential relationships between substance use and specific weight status categories (obesity, overweight, and underweight) have not been assessed. This study assessed prevalence of tobacco/nicotine, cannabis, and alcohol use by weight status categories in young adulthood. Methods: Of the 1322 young adults (18-29 years; 20.5 ± 2.3 years; 63% female; 42% Hispanic/Latino/a/x, 30% Asian-American/Asian, 18% Caucasian/White, 7% Multiracial, and 2% African-American/Black) from a public, urban university were surveyed on their health-risk behaviors in the spring and fall of 2021. Results: Multinomial logistic regression models assessed six-month follow-up substance use prevalence (never, lifetime but no past 30-d use, and past 30-d use) by baseline weight status (obese, overweight, underweight; reference: healthy weight). Obesity predicted lower odds of past 30-d nicotine vaping (aOR [95% CI] = 0.27 [0.08-0.92]). Overweight predicted higher odds of lifetime combustible cannabis (aOR [95% CI] = 1.58 [1.08-2.30]) and past 30-d binge drinking (aOR [95% CI] = 1.79 [1.12-2.85]). Underweight was associated with lower odds of lifetime cannabis vaping (aOR [95% CI] = 0.35 [0.12-0.99]) and combustible cannabis (aOR [95% CI] = 0.38 [0.16-0.87]). Conclusions: Differential relationships between obesity and overweight on tobacco/nicotine, cannabis, and alcohol use suggest greater specificity is needed when evaluating relationships between higher weight status and substance use. It appears that overweight young adults may be at higher risk of substance use than obese young adults. Greater efforts to consider multiple weight status groups, not just obese, may have significant implications for tobacco/nicotine prevention and intervention efforts targeting vulnerable populations.
Today, the rapid development, large volume, and global access of multimedia applications have demanded the shifting of network functionality from the central server to the near user. In recent times, Edge Computing (EC) and Information Centric Networking (ICN) have been presented as arising advances for content dissemination near the end user. The EC aims to provide content locally by reducing the burden of the core networks, while ICN allows content routing and forwarding based on content names directly. The inherent in-network caching feature of ICN facilitates caching by intermediate network nodes. The combined use of EC and ICN can efficiently handle content dissemination and ultimately improves user experience. In this regards, an ICN based edge caching scheme has been proposed for handling multimedia big data traffic in IoT based smart cities, while incorporating four caching attributes in its proposed design. Firstly, a layered network architecture has been presented that offers Device-to-Device (D2D) communication and ICN support at the application layer of Base station (BS) for utilizing caching of the requested content at edge of the network. Secondly, a decision on caching of contents at network nodes in layered network architecture has been presented based on various centrality measures, which supports efficient caching. Thirdly, this work offers caching of content near the delivery path in ICN network tiers, while leveraging near path caching for fast content dissemination. Lastly, reproactive caching where proactive caching is followed by reactive caching for controlling the network traffic during peak hours has been integrated in to the design model. The performance of the proposed scheme has been evaluated by conducting simulations in Icarus- an ICN caching simulator against various caching benchmark schemes. The results received from the experiments have shown significant performance improvement of our proposed scheme for different performance metrics including cache hit ratio, content retrieval delay, content path stretch, and internal link load.
Resource scarcity is a powerful construct in social sciences. However, explanations about how resources influence overall well‐being are difficult to generalize since much of the research on scarcity focuses on relatively affluent marketplace conditions, limiting its usefulness to large segments of the global population living in poverty. Conversely, poverty research provides cultural insights into resource deprivation, yet it stops short of explaining the systematic variation of scarce resources among impoverished individuals. To bridge these intellectual silos and advance a deeper understanding of scarcity, we integrate resource scarcity research, which builds upon a psychological tradition to understand various forms of everyday deprivation, with poverty research, which builds upon a sociological tradition to understand extreme and enduring deprivation. We propose a novel framework that integrates the concept of consumption adequacy and clarifies resource scarcity’s forms, intensity, duration, and dynamic trajectories. We leverage this framework to generate a research agenda and we propose ways to stimulate dialogue among scarcity and poverty scholars, policymakers, and organizations to help inform impoverished life circumstances and generate effective solutions.
Twin Artists: Unique Sources of Inspiration and Talent/Twin Research Reviews: Ethnic and Racial Factors Affecting Type of Twin Delivery; Outcomes in Twins Conceived Naturally and With Reproductive Assistance; Delivery Time for Growth-Discordant Twins; 3D Study of Twins’ Facial Resemblance/In the Media: Baseball Players With Divergent Careers; Basketball Twins in the Elite 8; Twins’ Grave and Epitaph; Twins Conceived Three Times in 2 Years; Twins in the Hockey Hall of Fame; Superfetated Twins
The unique sources of artistic inspiration and talent of twin artists are examined. The professional literature is rich with twin studies of creativity, but lacking when it comes to specific artistic domains — for example, painting and sculpting. The section that follows provides reviews of current research on ethnic and racial factors affecting type of twin delivery, pregnancy outcomes when twins are conceived naturally or with reproductive assistance, the effects of intrauterine growth discordance on the timing of twin delivery, and three-dimensional (3D) assessment of twins’ facial resemblance. The final section summarizes information about twins in the media. The stories include twins distinguished for both baseball playing and physical injuries, twins who reached the National College Athletic Association’s Elite 8, a twin pair’s grave and epitaph, a mother who conceived twins three times in 2 years, twins in the Hockey Hall of Fame, and a set of superfetated twins.
Twins reared apart are rare, especially twins raised in different countries and cultures. This report documents the behavioral, physical, and medical similarities and differences of monozygotic female cotwins, raised separately by an adoptive family in the United States and the biological family in South Korea. Similarities were evident in personality, self-esteem, mental health, job satisfaction and medical life history, consistent with genetic influence found by the Minnesota Study of Twins Reared Apart and related studies. An overall twin correlation across thirty-eight measures was r = 0.95, p < .001. In contrast with previous research, the twins' general intelligence and non-verbal reasoning scores showed some marked differences. Adding these cases to the psychological literature enhances understanding of genetic, cultural, and environmental influences on human development.
A Twin Loss Survey was completed by MZ and same-sex DZ twins following loss of a cotwin and nontwin relatives. Twin survivors (N = 612; MZ = 506; DZ, n = 106) included twins whose age at loss was 15 years or older. Participation age was M = 47.66 years (SD = 15.31). Hamilton's inclusive fitness theory generated two hypotheses: (1) MZ twins will recall greater grief intensity at loss than DZ twins; (2) loss of a twin will receive greater grief intensity ratings than loss of nontwin relatives. We expected females to grieve more intensely for deceased cotwins than males. Males cannot be certain a child conceived by their partner is theirs (paternity uncertainty). As such, grief for the loss of a twin brother (whose child would indirectly transmit common genes) should be reduced by surviving male twins, relative to surviving female twins. Part I: Hypotheses regarding grief intensity were supported. Part II: A structural equation model was estimated; grief significantly mediated relationships between exogenous and endogenous predictors and grief predicted greater preoccupation and less effective coping. MZ twins and females expressed greater grief intensity than DZ twins and males. Associations between genetic relatedness and grief, consistent with evolutionary-based predictions, are highlighted.
Osmoregulation is a conserved cellular process required for the survival of all organisms. In protists, the need for robust compensatory mechanisms that can maintain cell volume and tonicity within physiological range is even more relevant, as their life cycles are often completed in different environments. Trypanosoma cruzi, the protozoan pathogen responsible for Chagas disease, is transmitted by an insect vector to multiple types of mammalian hosts. The contractile vacuole complex (CVC) is an organelle that senses and compensates osmotic changes in the parasites, ensuring their survival upon ionic and osmotic challenges. Recent work shows that the contractile vacuole is also a key component of the secretory and endocytic pathways, regulating the selective targeting of surface proteins during differentiation. Here we summarize our current knowledge of the mechanisms involved in the osmoregulatory processes that take place in the vacuole, and we explore the new and exciting functions of this organelle in cell trafficking and signaling.
Although linguistic and nonlinguistic cues help young children infer meaning when presented with unfamiliar words, little is known about how syntactic information and early bilingual experience shape word learning. This study examined how monolingual and bilingual 24- to 30-month-olds’ disambiguation of novel words during a mutual exclusivity task differs as a function of syntactic cues, age, and productive vocabulary. English monolinguals and Spanish-English bilinguals were presented with familiar and novel objects within a syntactic context (e.g., “Give me the blick!”) or in isolation (e.g., “Blick!”). Results showed that monolinguals and bilinguals adhered to mutual exclusivity more often when provided with syntactic cues than when those cues were absent. Furthermore, bilinguals’ mutually exclusive disambiguation of novel words increased with age, but only when syntactic cues were available. These results provide insight into factors that influence children’s disambiguation of novel words. The theoretical implications of these findings are discussed.
Exposure to phenols is widespread since they are found in many everyday products. Given that phenols are considered endocrine disrupting chemicals with the potential to interfere with hormonal activities, they could have adverse effects on female reproductive health. We analyzed cross-sectional data from the National Health and Nutrition Examination Survey (NHANES), 2003-2006 to examine the association between phenols and endometriosis and uterine leiomyoma (fibroids). Levels of bisphenol A (BPA), benzophenone-3, and triclosan were measured using urine samples, and information on endometriosis and fibroids diagnoses as well as other relevant characteristics were ascertained using self-reported questionnaires. Multivariate logistic regression with odds ratios (ORs) and 95% confidence intervals (CIs) were used to quantify the association between each phenol and female gynecologic condition. Our study included 700 women, of which 53 women had endometriosis and 107 women had fibroids. We found exposure to BPA to be statistically significantly positively associated with endometriosis (p=0.05); women in the highest exposure quartile had over the three times the odds of having endometriosis relative to women in the lowest quartile (OR=3.58, 95% CI 1.00-12.89). None of the phenols considered were significantly associated with fibroids. Overall, exposure to BPA increased the odds of having endometriosis, and there appeared to be a dose-response relationship. This suggests that BPA may play a role in the pathogenesis of endometriosis although the cross-sectional nature of NHANES data is a methodological limitation. Additional research on the impact of endocrine disrupting chemicals, like phenols, on female reproductive health should be conducted.
This study examines the relationship between diatom assemblages from lake sediment surface samples and water depth at Kelly Lake, California. A total of 40 surface sediment samples (top 5 cm) were taken at various depths within the small (3.4 ha) five-meter-deep lake. Secchi depths, water temperature, pH, salinity, conductivity, and total dissolved solids were also measured. Some diatom species showed distinct association with depth (e.g., Fragilaria crotonensis, Nitzschia semirobusta) . The relationship between the complete diatom assemblages and water depth was analyzed and assessed by depth-constrained cluster analysis, a one-way analysis of similarity, and principal components analysis. Statistically significant differences were found between the assemblages associated with shallow depth (0 m – 1.25 m), mid-depth (1.25 m – 3.75 m), and deep depth (3.75 m – 5.2 m) locations. The relationship between diatom assemblages and lake depth allowed two transfer models to be developed using the Modern Analogue Technique (MAT) and Weighted Averaging Partial Least Squares (WA-PLS). These models were compared and assessed by residual scatter plots. We demonstrate that the diatom assemblages in the sediments of Kelly Lake are differentiated by lake depth. The results indicate that diatom-inferred transfer models based on surface sediment samples from a single lake can be a useful tool for studying past hydroclimatic variability (e.g. lake depth) from cores taken from such lakes in California.
