The CARE Principles for Indigenous Data Governance

The current movement toward open data and open science does not fully engage with Indigenous Peoples rights and interests. Existing principles within the open data movement (e.g. FAIR: findable, accessible, interoperable, reusable) primarily focus on characteristics of data that will facilitate increased data sharing among entities while ignoring power differentials and historical contexts. The emphasis on greater data sharing alone creates a tension for Indigenous Peoples who are also asserting greater control over the application and use of Indigenous data and Indigenous Knowledge for collective benefit.

This includes the right to create value …

Why We Publish Where We Do: Faculty Publishing Values And Their Relationship To Review, Promotion And Tenure Expectations, Meredith T. Niles, Lesley A. Schimanski, Erin Christy Mckiernan, Juan P. Alperin

Copyright, Fair Use, Scholarly Communication, etc.

Using an online survey of academics at 55 randomly selected institutions across the US and Canada, we explore priorities for publishing decisions and their perceived importance within review, promotion, and tenure (RPT). We find that respondents most value journal readership, while they believe their peers most value prestige and related metrics such as impact factor when submitting their work for publication. Respondents indicated that total number of publications, number of publications per year, and journal name recognition were the most valued factors in RPT. Older and tenured respondents (most likely to serve on RPT committees) were less likely to value …

Fractional Authorship & Publication Productivity, Kate Gasson, Rachel Herbert, Alex Ponsford

Copyright, Fair Use, Scholarly Communication, etc.

Authors divide their research output across publications, contributing via research collaborations

The trend is for authors to produce more publications per year (increased fractionalization) but for the overall number of publications per author to decrease

We suggest that the effort required to participate in research collaborations is a factor in the decrease in publications per author

Are authors collaborating more in response to the pressure to publish?

Growth in the number of scholarly publications each year has been well documented (e.g., Bornmann & Mutz, 2015, Figure 1). But how has that growth been achieved? Is it purely due to increasing …

The Home And Child-Care: Are Preschoolaged Children Getting Mixed Food-Related Messages?, Noereem Zenaida Mena

Open Access Dissertations

Statement of the Problem: In the United States, nearly 14% of preschool-aged children (ages 2 to 5) are obese. Additionally, disparities persist, with the highest prevalence of obesity among Hispanic preschool-aged children (17% vs. 11% non-Hispanic Black and 3.5% non- Hispanic White preschool-aged children). Establishing healthy eating habits in early childhood is critical and providing children with similar opportunities to practice healthy eating habits independently at home and in child care is thought to reinforce the development of healthy eating habits early in life. However, there is limited information regarding how parents and childcare providers communicate about child-nutrition, including …

The Need For Speed: How Quickly Do Preprints Become Published Articles?, Rachel Herbert, Kate Gasson, Alex Ponsford

Copyright, Fair Use, Scholarly Communication, etc.

bioRxiv’s option for authors to submit biology preprints directly to journals typically speeds up publication of articles by nearly 2 weeks—an advantage for authors who are keen to get their work published quickly

Authors approach ‘preprinting’ in different ways: while most post a preprint before submitting to a journal, just over a third of preprints were submitted to and accepted by a journal before the preprint appeared on bioRxiv

Biology preprints with just one version are published 2 weeks more quickly than those with multiple versions

A Comparative Study Of Author Gender Identification, Tuğba Yildiz

Turkish Journal of Electrical Engineering and Computer Sciences

In recent years, author gender identification has gained considerable attention in the fields of information retrieval and computational linguistics. In this paper, we employ and evaluate different learning approaches based on machine learning (ML) and neural network language models to address the problem of author gender identification. First, several ML classifiers are applied to the features obtained by bag-of-words. Secondly, datasets are represented by a low-dimensional real-valued vector using Word2vec, GloVe, and Doc2vec, which are on par with ML classifiers in terms of accuracy. Lastly, neural networks architectures, the convolution neural network and recurrent neural network, are trained and their …

Combined Feature Compression Encoding In Image Retrieval, Lu Huo, Leijie Zhang

Turkish Journal of Electrical Engineering and Computer Sciences

Recently, features extracted by convolutional neural networks (CNNs) are popularly used for image retrieval. In CNN representation, high-level features are usually chosen to represent the images in coarse-grained datasets, while mid-level features are successfully applied to describe the images for fine-grained datasets. In this paper, we combine these different levels of features as a joint feature to propose a robust representation that is suitable for both coarse-grained and fine-grained image retrieval datasets. In addition, in order to solve the problem that the efficiency of image retrieval is influenced by the dimensionality of indexing, a unified subspace learning model named spectral …

Evolutionary Approaches For Weight Optimization In Collaborative Filtering-Based Recommender Systems, Sevgi̇ Yi̇ği̇t Sert, Yilmaz Ar, Gazi̇ Erkan Bostanci

Turkish Journal of Electrical Engineering and Computer Sciences

Collaborative filtering is one of the widely adopted approaches in recommender systems used for e-commerce applications, stating that users having similar tastes will have similar preferences in the future.

A Novel And Unified Approach For Averaged Channel Capacity And Averagedeffective Capacity Analyses Of Diversity Combining And Multihop Transmissionschemes In Flat Fading Environments, Ferkan Yilmaz, Mohamed-Slim Alouini

Turkish Journal of Electrical Engineering and Computer Sciences

n this paper, we introduce an Lp -norm aggregation to present a signal-to-noise ratio expression unified not only for such diversity combining schemes as equal-gain combining, maximal-ratio combining, and selection combining, but also for such transmission techniques as multihop transmission. Accordingly, we propose two moment-generating function-based approaches that both respectively unify the exact analyses of the averaged channel capacity and averaged effective capacity over generalized fading channels with respect to the diversity combining and multihop transmission schemes. Finally, the mathematical formalism is illustrated by numerical special cases and verified by simulations.

Finite Integration Method With Chebyshev Expansion For Finding Numerical Solution Of Nonlinear And Fractional Order Differential Equations, Ampol Duangpan

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this dissertation, we develop the finite integration method by using Chebyshev polynomial expansion (FIM-CPE) for solving one- and two-dimensional nonlinear differential equations. The developed FIM-CPE can be used on any domains. Then, we utilize our FIM-CPE to deal with the spatial variable and the forward difference quotient to handle the derivative involving temporal variable. Thus, the numerical algorithms based on this idea are devised to overcome three nonlinear problems including one-dimensional Burgers' equation with shock wave, time-fractional Benjamin-Bona-Mahony-Burgers' equation and two-dimensional nonlinear Poisson equation over irregular domains. Moreover, we examine our algorithms with several experimental examples by comparing the …

Stochastic Differential Equation With Jumps For Tilapia Population, Kanitin Sukchum

Chulalongkorn University Theses and Dissertations (Chula ETD)

Tilapia population with harvesting in the tilapia farm can be modeled by an ordinary differential equation (ODE). In real life, tilapia population can be affected by many factors. To make the model for tilapia population more realistic, we develop the ODE into the stochastic differential equation (SDE) together with jumps that represent the epidemic occuring for tilapia. Furthermore, we study the effect of some important parameters in the model to the number of tilapia in the tilapia farm via simulation. Both SDEs for tilapia population with and without jumps are simulated by using Euler-Maruyama and jump-adapted Euler methods.
