Pairing Technology with Effective Literacy Strategies

School districts and policy makers have pushed schools toward tomorrow, without preparing them for today. Regardless of whether a district decides to spend thousands of dollars becoming a 1-1 school (i.e. one device per one student), or save money by instituting a bring your own device policy (B.Y.O.D), the results are the same. Students and teachers have been thrown into a digital world without first receiving training on personal and professional use of technology. Though I originally set out to combine literacy strategies and technology, I realized I needed to first build own my personal knowledge based on education technologies and digital literacy. I explored my own digital comprehension and organization strategies in order to better understand the learning process of adapting new technologies in the secondary classroom. Additionally, I utilized my student teaching placement— a bring your own device school— to survey students and teachers about their own technological learning curve. Thus, my project was reborn. A semester-long research process about educational technologies and digital literacies began. Along the way, I decided to create a digital text using iBooks Author, a free application available on Apple products. Based on academic research, personal experience, and surveys from both students and teachers at Westerly High School, The Beginners Guide to Technology Integration offers two unique perspectives: the student and the teacher. This combined approach will inform teachers about their students’ digital needs and habits as well as educational technologies to transform their classroom into a 21st century digital learning environment

A Piece of Evolution of Occupational Therapy in North Dakota: Life History of Rhoda Erhardt, MS, OTR/L, FAOTA

This life history is one of 29 life history interviews which are a part of a larger project, Life Histories of Individuals Who Have Been Influential in Developing Occupational Therapy in North Dakota and Wyoming. The purpose of the project is to gather information about the history and evolution of OT practice in North Dakota and Wyoming through life histories of individuals who have been influential in developing OT in these two states. It is anticipated that the life history process will be a powerful way to gather this information. By using a life history approach, this study focused on the participant, Rhoda Erhardt’s, involvement in the evolution of OT practice. This study intends to provide current and future generations of occupational therapists with a view of the history and how OT practice has evolved from its inception to current practice in North Dakota and Wyoming. Rhoda Erhardt is a well known practitioner in the state of North Dakota and has achieved many accomplishments throughout the years. In order to gather information about her experiences as an occupational therapist, the researchers conducted an over the phone interview with Rhoda

Antiviral Immunity in the Fruit Fly, Drosophila melanogaster

The fruit fly, Drosophila melanogaster, is an extremely useful model to study innate immunity mechanisms. A fundamental understanding of these mechanisms as they relate to various pathogens has come to light over the past 30 years. The discovery of Toll‐like receptors and their recognition of shared molecules (pathogen‐associated molecular patterns or PAMPs) among pathogenic bacteria were the first detailed set of receptors to be described that act in innate immunity. The immune deficiency pathway (Imd) described in D. melanogaster functions in a very similar way to the Toll pathway in recognizing PAMPs primarily from Gram‐negative bacteria. The discovery of small interfering RNAs (RNAi) provided a means by which antiviral immunity was accomplished in invertebrates. Another related pathway, the JAK/STAT pathway, functions in a similar manner to the interferon pathways described in vertebrates, also providing antiviral defense. Recently, autophagy was also shown to function as a protective pathway against virus infection in D. melanogaster. At least three of these pathways (Imd, JAK/STAT, and RNAi) show signal integration in response to viral infection, demonstrating a coordinated immune response against viral infection. The number of pathways and the integration of them reflect the diversity of pathogens to which innate immune mechanisms must be able to respond. The viral pathogens that infect invertebrates have developed countermeasures to some of these pathways, in particular to RNAi. The evolutionary arms race of pathogen vs. host is ever ongoing

Trends and Opportunities in Tick-Borne Disease Geography

Tick-borne diseases are a growing problem in many parts of the world, and their surveillance and control touch on challenging issues in medical entomology, agricultural health, veterinary medicine, and biosecurity. Spatial approaches can be used to synthesize the data generated by integrative One Health surveillance systems, and help stakeholders, managers, and medical geographers understand the current and future distribution of risk. Here, we performed a systematic review of over 8,000 studies and identified a total of 303 scientific publications that map tick-borne diseases using data on vectors, pathogens, and hosts (including wildlife, livestock, and human cases). We find that the field is growing rapidly, with the major Ixodes-borne diseases (Lyme disease and tick-borne encephalitis in particular) giving way to monitoring efforts that encompass a broader range of threats. We find a tremendous diversity of methods used to map tick-borne disease, but also find major gaps: data on the enzootic cycle of tick-borne pathogens is severely underutilized, and mapping efforts are mostly limited to Europe and North America. We suggest that future work can readily apply available methods to track the distributions of tick-borne diseases in Africa and Asia, following a One Health approach that combines medical and veterinary surveillance for maximum impact

Analysis of immune-related genes during Nora virus infection of <em>Drosophila melanogaster</em> using next generation sequencing

Drosophila melanogaster depends upon the innate immune system to regulate and combat viral infection. This is a complex, yet widely conserved process that involves a number of immune pathways and gene interactions. In addition, expression of genes involved in immunity are differentially regulated as the organism ages. This is particularly true for viruses that demonstrate chronic infection, as is seen with Nora virus. Nora virus is a persistent non-pathogenic virus that replicates in a horizontal manner in D. melanogaster. The genes involved in the regulation of the immune response to Nora virus infection are largely unknown. In addition, the temporal response of immune response genes as a result of infection has not been examined. In this study, D. melanogaster either infected with Nora virus or left uninfected were aged for 2, 10, 20 and 30 days. The RNA from these samples was analyzed by next generation sequencing (NGS) and the resulting immune-related genes evaluated by utilizing both the PANTHER and DAVID databases, as well as comparison to lists of immune related genes and FlyBase. The data demonstrate that Nora virus infected D. melanogaster exhibit an increase in immune related gene expression over time. In addition, at day 30, the data demonstrate that a persistent immune response may occur leading to an upregulation of specific immune response genes. These results demonstrate the utility of NGS in determining the potential immune system genes involved in Nora virus replication, chronic infection and involvement of antiviral pathways

Extracellular Ca2+ Is Required for Fertilization in the African Clawed Frog, Xenopus laevis

The necessity of extracellular Ca2+ for fertilization and early embryonic development in the African clawed frog, Xenopus laevis, is controversial. Ca2+ entry into X. laevis sperm is reportedly required for the acrosome reaction, yet fertilization and embryonic development have been documented to occur in high concentrations of the Ca2+ chelator BAPTA. Here we sought to resolve this controversy.Using the appearance of cleavage furrows as an indicator of embryonic development, we found that X. laevis eggs inseminated in a solution lacking added divalent cations developed normally. By contrast, eggs inseminated in millimolar concentrations of BAPTA or EGTA failed to develop. Transferring embryos to varying solutions after sperm addition, we found that extracellular Ca2+ is specifically required for events occurring within the first 30 minutes after sperm addition, but not after. We found that the fluorescently stained sperm were not able to penetrate the envelope of eggs inseminated in high BAPTA, whereas several had penetrated the vitelline envelope of eggs inseminated without a Ca2+ chelator, or with BAPTA and saturating CaCl2. Together these results indicate that fertilization does not occur in high concentrations of Ca2+ chelators. Finally, we found that the jelly coat includes >5 mM of readily diffusible Ca2+.Taken together, these data are consistent with requirement of extracellular Ca2+ for fertilization. Based on our findings, we hypothesize that the jelly coat surrounding the egg acts as a reserve of readily available Ca2+ ions to foster fertilization in changing extracellular milieu

Topic Strategies and the Internal Structure of Nominal Arguments in Greek and Italian

In this article, we argue that a set of unexpected contrasts in the interpretation of clitic-left-dislocated indefinites in Greek and Italian derive from structural variation in the nominal syntax of the two languages. Greek resists nonreferential indefinites in clitic left-dislocation, resorting to the topicalization of an often bare noun for nonreferential topics. By contrast, clitic left-dislocation is employed in Italian for topics regardless of their definite/indefinite interpretation. We argue that this contrast is directly linked to the wide availability of bare nouns in Greek, which stems from a structural difference in the nominal syntax of the two languages. In particular, we hypothesize that Greek nominal arguments lack a D layer. Rather, they are Number Phrases. We situate this analysis in the context of Chierchia’s (1998) typology of nominals. We argue that, on a par with Italian nouns, Greek nouns are [−arg, +pred]. However, they do not employ a syntactic head (D) for type-shifting to e . Rather, they resort to covert type-shifting, a hypothesis that is necessary to account for the distribution and interpretations of bare nouns in Greek, vis-à-vis other [−arg, +pred] languages like Italian and French. </jats:p
