Technical Specifications

The Geometer is a new handheld USB device that facilitates a relatively accurate measurement of the declination to a target with instantaneous recording of this and other data. The Geometer offers several advantages over traditional clinometers used in aerial surveys, including easier target pinpointing and tracking, more consistent angle measurements, and integration with software data collection packages. In this note we provide technical specifications for the device and its associated software, and describe a new aerial survey data collection programme that takes full advantage of the features of the Geometer. We have tested this device extensively during aerial surveys and highlight the utility of the hardware as well as ways in which the technology could be improved.

Definition Of

Bias, precision and accuracy have been studied extensively in wildlife population estimation including aerial surveys. A review of the literature shows that the concepts of bias and precision are used broadly consistently. Aerial survey data from known populations of feral pig carcases and white-tailed deer show that few density estimates are unbiased and precise. Research is needed, however, to clarify how much bias and how much precision are enough for the various types of wildlife management activities. Accuracy is used in two closely related but different ways. One set of definitions of accuracy relates to deviations from the true value (bias) and the second set relates to squared deviations from the true value (bias and precision). The implications are that authors are encouraged to clearly state which definition of accuracy they use, or focus solely on bias and precision.

The rapid population of beginner voters in Indonesia than in 2004-2009 should be a calculation in influencing election results. Perception of beginner voters on the performance of electoral institutions in a sense it is important to be discussed because of the independence and professionalism an important factor general election success.This study uses the quantitative research survey. Data collection techniques by questionnaire. The sampling technique is done with strafied random sampling technique. The survey conducted on students at nine universities in YogyakartaResults from this study: First, Knowledge voters on electoral institutions. Voters who do not know Bawaslu that as many as 49.7 percent of respondents. As for the KPU as much as 65.1 percent of voters know; Second, the level of confidence in electoral institutions quite good 57.2 percent of voters believe; Third, the perception of the neutrality of electoral institutions 50.5 percent; and Fourth, the Electoral Institute of Professionalism 48.1 percent of voters declared "professional"; and Fifth, Satisfaction with the performance of the KPU was satisfied only 44.4 percent, while 40.5 percent expressed "not satisfied.In conclusion the perception of beginner voters on the performance of electoral institutions KPU and Bawaslu overall is still relatively low and should be increased by way of socialization to voters. Keywords: general election, performance of electoral institutions, beginner voters, voter perceptions Pesatnya populasi pemilih pemula di Indonesia dari tahun 2004-2009patut menjadi perhitungan dalam mempengaruhi hasil Pemilu. Persepsi pemilih pemula terhadap kinerja peyelenggara Pemilu di rasa penting untuk di bahas dikarenakan independensi dan profesionalitas peyelenggara merupakan faktor penting keberhasilan peyelenggaraanPemilu.Penelitian ini menggunakan metode penelitian kuantitatif yakni survei. Teknik pengumpulan data dengan kuesioner. Teknik pengambilan sampel dilakukan dengan teknik strafied random sampling. Survei dilakukan terhadap mahasiswa di 9 perguruan tinggi di DIY.Hasil dari penelitian ini: Pertama, Pengetahuan pemilih terhadap lembaga penyelenggara pemilihan umum.pemilih pemula yang tidak mengetahui Bawaslu yakni sebanyak 49,7 persen responden. Sedangkan untuk KPU sebanyak 65,1 persen pemilih pemula mengetahui; Kedua, Tingkat kepercayaan terhadap lembaga peyelenggara pemilihan umum cukup baik 57,2 persen pemilih pemula percaya; Ketiga, Persepsi terhadap netralitas lembaga penyelenggara pemilihan umum 50,5 persen; dan Keempat, Profesionalisme Lembaga Pemilu 48,1 persen pemilih pemula menyatakan “professional”.; dan Kelima, Kepuasan terhadap kinerja KPU menyatakan puas hanya 44,4 persen sedangkan 40,5 persen lainnya menyatakan “tidak puas”.Kesimpulannya persepsi pemilih pemula terhadap kinerja peyelenggaraan pemilu yakni KPU dan Bawaslu secara keseluruhan masih tergolong rendah dan harus dilakukan peningkatan dengan cara sosialisasi terhadap pemilih pemula. Kata Kunci: pemilihan umum, pemilih pemula, persepsi pemilih, kinerja peyelenggara pemilu

A dense digital surface model is one of the products generated by using UAV aerial survey data. Today more and more specialized software are supplied with modules for generating such kind of models. The procedure for dense digital model generation can be completely or partly automated. Due to the lack of reliable criterion of accuracy estimation it is rather complicated to judge the generation validity of such models. One of such criterion can be mobile laser scanning data as a source for the detailed accuracy estimation of the dense digital surface model generation. These data may be also used to estimate the accuracy of digital orthophoto plans created by using UAV aerial survey data. The results of accuracy estimation for both kinds of products are presented in the paper.

The concluding chapter emphasizes several central points and contributions of the book. It first provides a summary of the extent of the emerging infrastructure that the Comparative Agendas Project (CAP) has developed. It shows the many possibilities provided by this infrastructure, as illustrated by the comparative chapters in the volume. The chapter goes to discuss the achievements in terms of data collection and comparability. Finally, the chapter explores possible future directions of research for the CAP and, beyond, the field of comparative public policy. In particular, it could positively contribute to the study of the consequence of differences in bureaucratic structures. Similarly, the inclusion of media data has opened up new possibilities that have only just started to be explored. Finally, the study of “responsiveness” and its consequences for political behavior could also benefit from crossing, say, survey data with CAP data.

Over Time

Building on the foundation laid in Chapter 2, this chapter focuses specifically on the religious lives of emerging adults. Survey responses from multiple waves of data collection are used to show changes over time. The chapter focuses on change and continuity in the religious lives of emerging adults, while also showing how different religious traditions have fared in terms of influencing the lives of emerging adults. Taken together, the survey data show an overarching story of decline; yet under the surface there is movement both toward and away from religion.
