About the RAY Fellowship

Inspired by efforts to increase racial diversity in conservation, the Roger Arliner Young (RAY) Conservation Diversity Fellowship aims to increase and facilitate conservation-related career pathways for emerging leaders of color. The RAY Fellowship is a paid fellowship designed to equip recent college graduates with the tools, experiences, support, and community they need to become leaders in the conservation sector—one that, in our visions of the future, fully represents, includes, and is lead by the diverse communities, perspectives, and experiences of the United States.

The RAY Fellowship provides first-time career access opportunities for recent college graduates who do not have previous professional experience or a graduate degree. RAY Fellows are placed within one of our Member Organizations for a year-long paid fellowship position, with the resources and support to develop experiences that will launch them onto a path of career growth in conservation. Fellows work with mentors, grow their networks, and forge lasting relationships with their cohort of Fellows. RAY Fellowship positions are full-time paid positions with competitive entry-level salaries plus benefits. Fellows will also receive a stipend of $1,000 to go towards professional development opportunities, in addition to coordinated professional development through RAY Member Organizations and the Environmental Leadership Program.

Eligibility & How to Apply

Eligible applicants will:

• Come from a racial / ethnic background underrepresented in conservation and demonstrate a commitment to the values of diversity, equity, and inclusion
• Be less than 2 years out of college and have a Bachelor's Degree by July 2019 (we are not considering individuals with graduate degrees at this time) 
• Have not had a full-time job in conservation 
• Have the ability to work in the United States and commit to the entire fellowship

Applications for the 2019 cycle are open and descriptions of Fellowship positions will be added on a rolling basis. Completed applications should include a CV or resume, a letter of support, two essays, and a short answer response. Visit our website at http://www.rayconservationfellows.org for application instructions and deadlines.

Exploratory data analysis methods to summarize, visualize and describe datasets. The main principal component methods are available, those with the largest potential in terms of applications: principal component analysis (PCA) when variables are quantitative, correspondence analysis (CA) and multiple correspondence analysis (MCA) when variables are categorical, Multiple Factor Analysis when variables are structured in groups, etc. and hierarchical cluster analysis. F. Husson, S. Le and J. Pages (2017) <doi:10.1201/b10345-2>.

A general purpose toolbox for personality, psychometric theory and experimental psychology. Functions are primarily for multivariate analysis and scale construction using factor analysis, principal component analysis, cluster analysis and reliability analysis, although others provide basic descriptive statistics. Item Response Theory is done using factor analysis of tetrachoric and polychoric correlations. Functions for analyzing data at multiple levels include within and between group statistics, including correlations and factor analysis. Functions for simulating and testing particular item and test structures are included. Several functions serve as a useful front end for structural equation modeling. Graphical displays of path diagrams, factor analysis and structural equation models are created using basic graphics. Some of the functions are written to support a book on psychometric theory as well as publications in personality research.

Indices, heuristics and strategies to help determine the number of factors/components to retain: 1. Acceleration factor (af with or without Parallel Analysis); 2. Optimal Coordinates (noc with or without Parallel Analysis); 3. Parallel analysis (components, factors and bootstrap); 4. lambda > mean(lambda) (Kaiser, CFA and related); 5. Cattell-Nelson-Gorsuch (CNG); 6. Zoski and Jurs multiple regression (b, t and p); 7. Zoski and Jurs standard error of the regression coeffcient (sescree); 8. Nelson R2; 9. Bartlett khi-2; 10. Anderson khi-2; 11. Lawley khi-2 and 12. Bentler-Yuan khi-2.
