College Student Perceptions of MyProgrammingLab and BlueJ in an Introductory Computing Course

Students in introductory computing courses face various challenges. Many learning systems are available to support teaching and learning in introductory computing courses. Empirical work examining the use of such learning systems is available, but limited. In this research, we gathered student perceptions of two learning systems MyProgrammingLab and BlueJ. Understanding student perceptions of learning systems and their impact on learning to program is valuable information for both instructors and students. In this analysis, we gathered student perceptions of MyProgrammingLab and BlueJ in three surveys towards the end of a 15-week semester. Although students encountered problems in MyProgrammingLab and BlueJ, more than three quarters of the students perceived MyProgrammingLab and BlueJ to be useful in helping develop their programming skills. Many students agreed that using MyProgrammingLab and BlueJ helped them better understand the course materials

Exploring Design Patterns as Evaluation Tools in Human Computer Interaction Education

In Human Computer Interaction (HCI), interest in design patterns and pattern languages has continued for decades. There are many potential benefits of design patterns and pattern languages described in the literature including reuse of quality solutions, providing a lingua franca, and their application as both design and evaluation tools. However, there is still a lack of empirical evidence in this area. Many of the questions and concerns raised in this area have yet to be addressed. Dearden and Finlay in their 2006 critical review provide an agenda that includes exploring appropriate ways to use pattern languages in education and design. This work explores the use of design patterns in HCI education and the use of design patterns as evaluation tools. The results of this exploration suggest that design patterns may be an effective tool to educate novice designers and design patterns may useful in evaluating designs

Patterns and Pattern Sites in HCI: An Analysis

Interest in patterns and pattern languages in Human Computer Interaction (HCI) continues. However, many of the questions and concerns in this area have yet to be addressed. These questions and concerns include lack of empirical evidence to support the claimed benefits, lack of a standard pattern format, and lack of an organizing principle. This paper describes an analysis of the design of pattern websites and their respective patterns. A systematic online search using multiple search engines and multiple search phrases was conducted in attempt to further understand the current state of affairs, including pattern format and organizing principles. The results suggest that the community has yet to adopt a standard pattern format. Although, the essence of Alexander’s patterns was found in most patterns. The findings highlight the progress that we, as a community, have made in some areas, but remind us that there is work to do in other areas

Hubungan Dukungan Keluarga dengan Kekambuhan pada Pasien Skizofrenia di Wilayah Kerja Puskesmas Samata Kabupaten Gowa

Peningkatan angka kekambuhan pada pasien skizofrenia setelah perawatan dapat mencapai 25%-50% dan akan menyebabkan fungsi sosialnya menjadi terganggu. Faktor penyebab terjadinya kekambuhan yaitu kurangnya peran keluarga dalam perawatan terhadap pasien skizofrenia. Penelitian ini bertujuan untuk mengetahui hubungan dukungan keluarga dengan kekambuhan pada pasien skizofrenia. Jenis penelitian yang digunakan adalah korelasional dengan menggunakan desain Cross Sectional. Teknik pengambilan sampel menggunakan Non probability sampling dengan teknik Purposive sampling. Sampel yang diperoleh sebanyak 41 orang yang memenuhi kriteria inklusi. Metode pengumpulan data menggunakan kuesioner. Uji statistic yang digunakan adalah Uji Chi-Square α 0,5. Hasil penelitian menunjukkan 15 (36,6%) responden memiliki dukungan keluarga kurang, 12 (29,3%) responden memiliki dukungan keluarga cukup dan 14 (34,1%) responden memiliki dukungan keluarga baik. Adapun kekambuhan dengan tingat kekambuhan jarang yaitu 23 (56,1%) dan responden dengan tingkat kekambuhan sering 18 (43,9%). Dari perhitungan tabulasi silang antara dukungan keluarga dengan kekambuhan menggunakan spss dengan uji chi-square di dapatkan hasil p-value 0,002 dengan taraf signifikan 0,05. Karena p value <0,05 maka dapat disimpulkan ada hubungan yang signifikan antara dukungan keluarga dengan kekambuhan pada pasien skizofrenia di Wilayah Kerja Puskesmas Samata Kabupaten Gowa. Kesimpulan dari penelitian yakni terdapat hubungan yang signifikan antara dukungan keluarga dengan kekambuhan pada pasien skizofrenia di Wilayah Kerja Puskesmas Samata Kabupaten Gowa

Implementation and evaluation of a new methane model within a dynamic global vegetation model: LPJ-WHyMe v1.3.1

For the first time, a model that simulates methane emissions from northern peatlands is incorporated directly into a dynamic global vegetation model. The model, LPJ-WHyMe (LPJ &lt;B&gt;W&lt;/B&gt;etland &lt;B&gt;Hy&lt;/B&gt;drology and &lt;B&gt;Me&lt;/B&gt;thane), was previously modified in order to simulate peatland hydrology, permafrost dynamics and peatland vegetation. LPJ-WHyMe simulates methane emissions using a mechanistic approach, although the use of some empirical relationships and parameters is unavoidable. The model simulates methane production, three pathways of methane transport (diffusion, plant-mediated transport and ebullition) and methane oxidation. A sensitivity test was conducted to identify the most important factors influencing methane emissions, followed by a parameter fitting exercise to find the best combination of parameter values for individual sites and over all sites. A comparison of model results to observations from seven sites resulted in normalised root mean square errors (NRMSE) of 0.40 to 1.15 when using the best site parameter combinations and 0.68 to 1.42 when using the best overall parameter combination

Understanding Differences in the Body Burden–Age Relationships of Bioaccumulating Contaminants Based on Population Cross Sections versus Individuals

Background: Body burdens of persistent bioaccumulative contaminants estimated from the cross-sectional biomonitoring of human populations are often plotted against age. Such relationships have previously been assumed to reflect the role of age in bioaccumulation
