Determination of energy barrier profiles for high-k dielectric materials utilizing bias-dependent internal photoemission

We utilize bias-dependent internal photoemission spectroscopy to determine the metal/dielectric/silicon energy barrier profiles for Au/HfO2/Si and Au/Al2O3/Si structures. The results indicate that the applied voltage plays a large role in determining the effective barrier height and we attribute much of the variation in this case to image potential barrier lowering in measurements of single layers. By measuring current at both positive and negative voltages, we are able to measure the band offsets from Si and also to determine the flatband voltage and the barrier asymmetry at 0 V. Our SiO2 calibration sample yielded a conduction band offset value of 3.03+/-0.1 eV. Measurements on HfO2 give a conduction band offset value of 2.7+/-0.2 eV (at 1.0 V) and Al2O3 gives an offset of 3.3+/-0.1 (at 1.0 V). We believe that interfacial SiO2 layers may dominate the electron transport from silicon for these films. The Au/HfO2 barrier height was found to be 3.6+/-0.1 eV while the Au/Al2O3 barrier is 3.5+/-0.1 eV

We Welcome the New Immigrants

From the very beginning of this project we have focused on taking a balanced approach to identifying the strengths and challenges of new immigrants in the Great Plains. Discussions of change in our world invariably focus on problems, and only occasionally on the strengths. We set out to look at new immigrants from a different perspective, in our view, a more realistic perspective: seeing the inherent strengths they possess as newcomers to our region and the gifts they bring, and examining the cultural assets the newcomers and the longer-term residents all can rely upon in working together to meet the inevitable challenges that an influx of new people brings to our world. What, then, have we learned about the new immigrants and the new immigrant families to the Heartland? What challenges do they face in their journey to create a safe, prosperous, and harmonious new home for themselves and their loved ones and friends? What strengths do they possess to accomplish these goals? What gifts do they bring to our region? Let\u27s go back to the original questions posed by the authors, and discuss what we have learned

Title IX and the Cleary Act: What Counselor Educators Must Know

Because of the far-reaching legal, monetary, academic, and public relations ramifications of the sex abuse scandal at Pennsylvania State University, campus administrators are reviewing and more strictly enforcing the mandatory reporting requirements of Title IX of the 1972 Education Amendments and the Clery Act related to sexual harassment and sexual violence. This creates challenges in didactic and clinical coursework for counselor educators who must balance adhering to university reporting guidelines with the ethical responsibilities to provide informed consent and maintain confidentially of information disclosed by students and their clients during training. Issues involved for counselor educators and student counselors-in-training, the process of securing appropriate exceptions to mandatory reporting, and a sample exception policy are presented

Addiction Counseling Practice Competencies and Curriculum in CACREP-Accredited Programs

Addiction counseling is a growing field with emerging practice competencies and standards that have implications for counselor education programs. This study examined addiction counseling practice competencies and curriculum elements in CACREP-accredited programs to determine curriculum and program needs. A survey of 62 CACREP programs found that programs are including addiction counseling content into the curriculum, employing faculty who have experience in addiction counseling, and addressing the skill practice competency by adding increased credit hours in addiction counseling and teaching from a didactic and constructivist pedagogy. Recommendations are made to align addiction counseling training curriculum, including adding an addiction counseling specialization track that incorporates practice experiences

The Use of Social Media in Counselor Education

Examined in this article are ways the use of social media can enhance a counselor education program’s activities in the areas of recruitment, curriculum, pedagogy, extracurricular student contact, and alumni connections. Also discussed are privacy, confidentiality, informed consent, boundary, copyright, liability, and free speech issues related to the administrative and instructional use of social media in a counselor education program. A social media policy is proposed to help counselor educators use this potent tool ethically and effectively

Nebraska Growers’ and Crop Consultants’ Knowledge and Implementation of Integrated Pest Management of Western Bean Cutworm

Western bean cutworm (WBC), Striacosta albicosta (Smith; Lepidoptera: Noctuidae), is a native noctuid pest of corn and dry beans in North America. While this pest has expanded its range greatly in recent years, historically it has consistently caused high yield losses in western Nebraska. A survey was distributed to growers, crop consultants and other agricultural professionals to obtain information about current management practices used for WBC. Questions covered multiple topics including: demographics, scouting practices, degree-day model use, confidence in management knowledge, Bt corn use, insecticide use, and considerations for biological control. There were 95 completed responses received by email. Respondents self-reported a significantly higher yield loss due to WBC in 2016 than in 2015 and 2014. Growers demonstrated less knowledge of WBC identification and management than crop consultants. There were frequent (58.45%) reports of Cry1F Bt corn providing decreased control against WBC. This survey identified major concerns for growers and agricultural professionals in Nebraska for WBC management. An improved understanding of WBC biology and education on management would be most beneficial for growers. Crop consultants would benefit from using more diverse management tactics including: biological control, rotation of insecticide mode-of-action, and diversifying Bt corn types

A Qualitative Analysis of Counseling Students\u27 Thoughts, Attitudes, and Beliefs about Addition Counseling and Treatment

An estimated 21.7 million people need treatment for their substance use problem. As barriers to treatment are removed with health care reform, this number will continue to grow. Simultaneous to this need for treatment, a workforce crisis is occurring in the addiction counseling field due to high turnover rates, an aging workforce, worker shortages, and lingering stigma about substance abuse. Given this climate, counselor education programs are challenged to develop programs that adequately train future counselors to address the unique needs of clients who are struggling with addiction and to better understand how students construct their knowledge regarding addictions and addiction counseling. The purpose of this study was to explore and qualitatively examine the development of counseling students’ thoughts, attitudes, and beliefs about addiction and treatment that may help educators understand how to better design addiction counseling curriculum to address attitude and self-awareness competencies. Themes identified in the study are explored as well as the implications for counselor educators
