When Might Human Indexing Be Strongly Justified, Julian Warner

Proceedings from the Document Academy

The paper is concerned with the justification for human indexing, in the modern era. We understand human indexing in a classic sense, of human description of information objects in accord with a controlled vocabulary.

A justification for human indexing would be, when it yields a value commensurate with its cost. A long historically established value for retrieval systems is selection power, or an enhanced capacity for informed choice for the searcher.

The question of the justification for human indexing is made analytically tractable by reversing the historical order of development. We ask, what forms of selection power are not readily …

Information Design: Textualization, Documentarization, Auctorialization, Manuel Zacklad

Proceedings from the Document Academy

In this article on information design, we will begin by recalling our definition of information anchored in an anthropological vision of communication, and we will then present Buckland’s ternary approach to information, which is in tune with our typology. Secondly, we will return to the notion of device (dispositif) to introduce information and communication devices, of which we will give a few examples. This will allow us, in the third section, to present the design of recorded information in all its richness and complexity, combining the issues of textualization, authorialization, and documentarization.

Poking The Monster: Worthwhile Or Whimsical?, Benjamin Barham

The Kabod

193,883 + 1 = 193,884. This seems like quite a trivial and elementary calculation, and technically, it is. However, this simple equation is an observation that helped establish the significance of the Monster group to mathematics as a whole. Although the Monster is an aspect of group theory, which is a vast area of mathematics, the majority of the information and research about the Monster has taken place in the last forty years, and thus, it potentially still has many mysteries to discover and add to the incomplete information obtained so far. Although it is a fascinating group by itself, …

Tech For Understanding: An Introduction To Assistive And Instructional Technology In The Classroom, Taylor Caldwell

The Kabod

This paper examines the different types of assistive and instructional technology available to students who are classified with one or more of the thirteen disabilities outlined in the Individuals with Disabilities Education Act (referred to as, IDEA). While the roles of assistive and instructional technology are different, there are many instances where their uses may overlap. Thus, while these two categories will be discussed separately, it should be noted that some information may be applied to each category and more than one piece of technology. The purpose of this paper is to provide an introduction to the world of assistive …

United States Department of Agriculture Wildlife Services: Staff Publications

Antimicrobial resistance is a threat to agricultural production and public health. In this proof-of-concept study, we investigated predicting antimicrobial sensitive/resistant (S/R) phenotypes and host sources of Escherichia coli (n = 128) based on differential fatty acid abundance. Myristic (14:0), pentadecanoic acid (15:0), palmitic (16:0), elaidic (18:19) and steric acid (18:0) were significantly different (α = 0.05) using a two-way ANOVA for predicting nalidixic acid, ciprofloxacin, aztreonam, cefatoxime, and ceftazidime S/R phenotypes. Additionally, analyses of palmitoleic (16:1), palmitic acid (16:0), methyl palmitate (i-17:0), and cis-9,10-methyleneoctadecanoic acid (19:0Δ) showed these markers were significantly different (α = 0.05) between isolates obtained from cattle …

The Vden: An Ipt Designed For Usability, Alexander Jaeger

Theses and Dissertations

Currently, headsets are the emphasis of Virtual Reality and the primary reason is that they are easy to develop and demo, lightweight, simple, and aordable. Historically, IPTs have required dedicated rooms due to their large size and experts in order to run and maintain them. These devices are expensive and can be complicated due to mirrors, the number of displays, and the overwhelming size of the infrastructure and computing clusters.The research in minimial IPTs have led up to the use of front-projection and dual GPU gaming computers, however this only works in a few cases. This thesis presents new work …

Performance Of Nitrogen As A Carrier Gas In Capillary Gas Chromatography Using A Thin Film Column, Brittany A. Handzo

Seton Hall University Dissertations and Theses (ETDs)

Gas chromatography (GC) is one of the most widely used analytical techniques for the separation and analysis of volatile compounds. Solids, liquids, and gases, organic and inorganic materials, and large molecular weight compounds can all be analyzed via this technique. Gas chromatographic separations are fast, accurate, and reliable. One of the reasons why these separations are so efficient is because of the carrier gas. The purpose of the carrier gas is to carry the injected sample through the column. It is known as the mobile phase and does not interact chemically with the sample. Common carrier gases include helium, hydrogen, …

Exploring Learning Style Preferences Of College Age Students With Attention Deficit Hyperactive Disorder (Adhd), Denise Nash-Luckenbach

Seton Hall University Dissertations and Theses (ETDs)

ADHD is a persistent neurobehavioral disorder in children with a prevalence rate of 5-10%. Symptoms of the disorder include inattentiveness, hyperactivity and impulsivity behavior. These symptoms are believed to have a great impact on the child’s cognitive and academic functions and children with ADHD are believed to have difficulty mastering basic academic skills. Historically, ADHD was believed to be a disorder only observed in children, however, it is estimated 66% of children with ADHD continue to be symptomatic as they enter adulthood. Students with a diagnosis of ADHD have higher dropout rates, lower standardized math and reading tests scores, and …

A "Choose-Your-Own" Classroom-Based Activity That Promotes Scientific Inquiry About Rna Interference, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

RNA interference (RNAi), the process that results in the degradation of a target gene’s mRNA, is a fundamental part of eukaryotic gene regulation and is also an important molecular technique that allows for experimental manipulation of gene expression without altering DNA sequences. Despite the importance of RNAi, there have been relatively few lecture-based activities designed to teach about the consequences of this process and counter common misconceptions. I present here an inquiry-based activity that is centered around a “choose your own experiment” design where students generate hypotheses and critically evaluate their ideas by choosing several simulated experiments. The activity presents …

Development Of A Low-Cost, Open Source Miniature Rotary Cell Culture System To Simulate Microgravity Within An Irradiated Environment, Elizabeth Vargis, Jr Dennison

Browse all Datasets

A major challenge for astronauts in long-duration space travel is combatting the hazardous spaceflight environment caused by microgravity and increased levels of ionizing radiation. Microgravity damages cellular DNA by increasing the production of harmful reactive oxygen species, while ionizing radiation damages DNA by creating double-stranded DNA (dsDNA) breaks. Cellular damage due to microgravity and radiation has been investigated using ground-based models, but most models consider microgravity and ionizing radiation alone, or asynchronously. Synchronous modeling better mimics spaceflight conditions and can be used to understand the combined effects of microgravity and ionizing radiation. However, commercially available devices to model microgravity and …

A Modified Approach By Using Prediction To Build A Best Threshold In Arx Model With Practical Application, Ahlam Ahmed Juma, Firas Ahammed Mohammed Al-Mohana

Baghdad Science Journal

The proposal of nonlinear models is one of the most important methods in time series analysis, which has a wide potential for predicting various phenomena, including physical, engineering and economic, by studying the characteristics of random disturbances in order to arrive at accurate predictions. In this, the autoregressive model with exogenous variable was built using a threshold as the first method, using two proposed approaches that were used to determine the best cutting point of [the predictability forward (forecasting) and the predictability in the time series (prediction), through the threshold point indicator]. B-J seasonal models are used as a second …

Heuristic One-Time Pad Encryption, James B. Joyce

Theses and Dissertations

Heuristic One-Time Pad (HOP) represents a methodology that is compliant with the requirements as established by Claude Shannon for a globally scalable and permanent encryption solution. The technique is not limited to encryption, rather, it also encompasses dynamic hashing and authentication. The two key Shannon-identified problems of continuous random number generation and secure distribution of encryption keys have been solved and are integral to the method. At each step of the algorithms, entropy is ‘1’ and unicity is ‘infinite’. All encryption key generation is independent of the value of the data being encrypted, and is dependent upon a combination of …
