Patterns of articles accepted for publication in the Journal of College Counseling from the past 12 years were reviewed in this metastudy. Results were described and statistically analyzed to identify trends over time in characteristics of authors, including sex, institutional classifications, employment setting, and domicile, and characteristics of articles, including article type, research design, sample size, types of participants, and statistical procedures.

The Education for All Movement (EFA) premises its commitment on the belief that quality education for all youth will ensure that they have equal access to skills and knowledge that will assist them in getting into gainful employment and enable them to participate fully in their societies. The importance and benefits of providing access to education and lifelong learning opportunities to youth has been acknowledged by a majority of world countries. These countries believe that quality education to youth means the ability to survive, to live and work in dignity, to participate fully in development, improve quality of their lives, to make informed decisions, and continuous learning – requirements for citizens of the 21st century. However, EFA mid-term report shows that as much as 42% of the world’s secondary school going-age youth were not enrolled in 2006, the majority of these youth are found in sub-Saharan Africa. There are a few empirical studies on the extent of school non-attendance and the profile of these youth not enrolled in an educational institution in the region. The study makes use of the Statistics South Africa dataset, Community Survey 2007, to determine the prevalence of school non-enrolment in South Africa among the 16 to 18 year olds. Second, the study attempts to establish the characteristics of the youth not enrolled in an education institution. To this end, the study analyzed the extent of non-enrolment prevalence, vi and the geographic distribution of the problem. In order to determine the geographic distribution of the problem, I first look at the size of school non-enrolment problem, nationally. I then analyse provincial, district and local patterns of school non-enrolment. Lastly, I analyse the data for identifiable individual and family factors that could be associated with the youth not currently enrolled in an educational institution. My analysis shows that the extent of youth between 16 and 18 years not enrolled in school is 16.6%, confirming recent government reports on prevalence among this age cohort. The study reveals physiographic and sub-population characteristics associated with non-enrolment in school. Disability, lack of access to social security grants, the low education level of a parent, or head of household that is not a parent are factors found to be related with low school participation by youth from those households. The study recommends a deeper investigation on the impact that the physiographic characteristics have on patterns of school enrolment.

Wide-bandgap semiconductors have made and are continuing to make a major impact on the power electronics world. The most common commercially available wide-bandgap semiconductors for power electronics applications are SiC and GaN devices. This paper focuses on the newest devices emerging that are made with these wide-bandgap materials. The static and dynamic characterization of six different SiC MOSFETs from different manufacturers are presented. The static characterization consists of the output characteristics, transfer characteristics and device capacitances. High temperature (up to 150 °C) static characterization provides an insight into the dependence of threshold voltage and on-state resistance on temperature. The dynamic characterizations of the devices are conducted by performing the double-pulse test. The switching characteristics are also tested at high temperature, with the presented results putting an emphasis on one of the devices. A comparison of the key characterization results summarizes the performance of the different devices. The characterization of one of the SiC MOSFETs is then continued with a short-circuit failure mode operation test. The device is subjected to non-destructive and destructive pulses to see how the device behaves. The non-destructive tests include a look at the performance under different external gate resistances and drain-source voltages. It is found that as the external gate resistance is increased, the waveforms get noisier. Also, as the drain-source voltage is increased, the maximum short-circuit current level rises. The destructive tests find the amount of time that the device is able to withstand short-circuit operation. At room temperature the device is able to withstand 4.5 μs whereas at 100 °C, the device is able to withstand 4.2 μs. It is found that despite the different conditions that the device is tested at for destructive tests, the energy that they can withstand is similar. This paper also presents the static and dynamic characterization of a 600 V, 2A, normallyoff, vertical gallium-nitride (GaN) transistor. A description of the fabrication process and the setup used to test the device are presented. The fabricated vertical GaN transistor has a threshold voltage of 3.3 V, a breakdown voltage of 600 V, an on-resistance of 880 mΩ, switching speeds up to 97 V/ns, and turn-on and turn-off switching losses of 8.12 µJ and 3.04 µJ, respectively, demonstrating the great potential of this device / MS

The purposes of this study were (1) to describe the persons twenty-five and older entering the teacher education program and seeking certification, and (2) to compare the persons twenty-five and older with a "typical" group of persons under twenty-five with respect to (a) ability, as measured by the Cooperative School and College Ability Test, (b) factors for entering teaching, as measured by "Factors Influencing the Decision to Become a Teacher," (c) attitudes held toward teaching, as measured by the Kerlinger Education Attitude Scale, (d) professional aspirations, and (e) role expectations, as measured by the Teacher Practices.

This investigation involved isolation and characterization of specific antigenic materials from known species of Streptomyces. The resulting antigens were then used to establish serological relationships between a number of different species. These groupings were, in turn, compared with similar studies recently established by the ISP, in which other taxonomic criteria were used. By these means, the serological characteristics of the Streptomyces were evaluated for their potential utility as added taxonomic tools in the establishment of species designations within this group.
