When the Politics of Food and Politics of Immigration Collide— Who Wins?

This commentary discusses how migrant workers play a key role in Maine and national agriculture, a key fact that is sometimes lost in the political rhetoric about “illegal immigrants.

A Two Study Structural Modeling Based Approach for Ensuring Retention of Empirical Structures and Optimizing Short Form Development.

Retaining an empirically supported model while reducing assessment parameters becomes challenging in short form measurement development. In 2012 Larwin and Harvey proposed a systematic item reduction approach using structural equation modeling (SIR-SEM). The SIR-SEM permits retention of a strong connection to an empirically supported model while reducing some of the challenges of working with a large measurement battery. The application of the SIR-SEM strategy to reduce the number of items needed to assess an empirical supported multidimensional model of impulsivity (Ginley, Whelan, Meyers, Relyea, & Pearlson, 2014) is presented using a two-study procedure. To complete the item reduction, a SAS/Stat version of the SIR-SEM was developed and model fit statistics with extensive empirical support were adopted. In Study 1, the SIR-SEM approach successfully eliminated 84% of items while retaining 33 items to assess three impulsivity dimensions: behavioral activation, preference for stimulation, and inhibition control. Study 2 tested the resulting 33-item impulsivity measure, the Memphis Impulsivity Measure (MIM), in an independent sample of participants. This second study confirmed model fit. Each of the three MIM dimensions had similar moderate levels of internal consistency. The Pearson correlations for each dimension score indicated good two-week test-retest reliability. The MIM was found to be largely demographically invariant and to have a significant relation with target risk behaviors including: gambling frequency, symptomology, and classification, alcohol use problems, and alcohol use classification, and drug use involvement and complexity of involvement

A Multidimensional Approach to Measuring How Impulsivity Corresponds to the Gambling of College Students

Impulsivity has been implicated as a contributing factor in the development of gambling problems among college students, but attempts to confirm this relation has been inconsistent. An explanation for incongruous findings is that impulsivity may be multidimensional and differentially predictive of behaviors. Utilizing a diverse sample of college students, a factor analysis of self-report measures of impulsivity revealed a three-factor structure of Behavioral Activation, Preference for Stimulation, and Inhibition Control that was remarkably similar to the structure found by Meda and colleagues (2009). Low risk and symptomatic gamblers scored significantly lower on Behavioral Activation and Inhibition Control than non-gamblers. Conversely, low risk and symptomatic gamblers scored significantly higher on Preference for Stimulation. Prevalence of gambling and gambling activity preference for this sample was also assessed

Magnetically Mediated Transparent Conductors: In2_2O3_3 doped with Mo

First-principles band structure investigations of the electronic, optical and magnetic properties of Mo-doped In$_2$O$_3$ reveal the vital role of magnetic interactions in determining both the electrical conductivity and the Burstein-Moss shift which governs optical absorption. We demonstrate the advantages of the transition metal doping which results in smaller effective mass, larger fundamental band gap and better overall optical transmission in the visible -- as compared to commercial Sn-doped In$_2$O$_3$. Similar behavior is expected upon doping with other transition metals opening up an avenue for the family of efficient transparent conductors mediated by magnetic interactions

Metallization for Self Aligned Technology: Cooperative Research and Development Final Report, CRADA Number CRD-08-295

In this CRADA NREL will modify/develop metallization inks that are compatible with 1366 Technologies technology. Various methods of deposition will be used to apply the inks to the textured silicon substrates. The goal of the project is to minimize the contact resistance while maximizing the cell efficiency

Preparation of delafossite CuFeO2 thin films by rf-sputtering on conventional glass substrate

CuFeO2 CuFeO2 is a delafossite-type compound and is a well known p-type semiconductor. The growth of delafossite CuFeO2 thin films on conventional glass substrate by radio-frequency sputtering is reported. The deposition, performed at room temperature leads to an amorphous phase with extremely low roughness and high density. The films consisted of a well crystallized delafossite CuFeO2 after heat treatment at 450 °C in inert atmosphere. The electrical conductivity of the film was 1 mS/cm. The direct optical band gap was estimated to be 2 eV
