Privacy and Confidentiality in Adoption Research: Perspectives from the Minnesota/Texas Adoption Research Project
There is currently a focus in adoption research on the processes that influence adoption-related adjustment (Palacios & Brodzinsky, 2011). To examine these processes, it is necessary to study the adoption network as a whole. This may include adoptive families and birth families. Research with all types of families introduces a number of ethical considerations (Margolin et al., 2005). There may be unique privacy and confidentiality concerns when working with families in the adoption network. The purpose of the current study is to outline privacy and confidentiality issues that arise when working with the adoption network. we also provide examples of how to address these issues using procedures from the Minnesota/Texas Adoption Research Project

Typical tropospheric aerosol backscatter profiles for Southern Ireland: The Cork Raman lidar
A Raman lidar instrument (UCLID) was established at the University College Cork as part of the European lidar network EARLINET. Raman backscatter coefficients, extinction coefficients and lidar ratios were measured within the period 28/08/2010 and 24/04/2011. Typical atmospheric scenarios over Southern Ireland in terms of the aerosol load in the planetary boundary layer are outlined. The lidar ratios found are typical for marine atmospheric condition (lidar ratio ca. 20–25 sr). The height of the planetary boundary layer is below 1000 m and therefore low in comparison to heights found at other lidar sites in Europe. On the 21st of April a large aerosol load was detected, which was assigned to a Saharan dust event based on HYSPLIT trajectories and DREAM forecasts along with the lidar ratio (70 sr) for the period concerned. The dust was found at two heights, pure dust at 2.5 km and dust mixing with pollution from 0.7 to 1.8 km with a lidar ratio of 40–50 sr
Broadband cavity-enhanced absorption spectroscopy with incoherent light
Although broadband incoherent light does not efficiently couple into a high-finesse optical cavity, its transmission is readily detectable and enables applications in cavity-enhanced absorption spectroscopy in the gas phase, liquid phase and on surfaces. This chapter gives an overview of measurement principles and experimental approaches implementing incoherent light sources in cavity-enhanced spectroscopic applications. The general principles of broadband CEAS are outlined and general “pros and cons” discussed, detailing aspects like cavity mirror reflectivity calibration or the establishment of detection limits. Different approaches concerning light sources, cavity design and detection schemes are discussed and a comprehensive overview of the current literature based on a methodological classification scheme is also presented
The Rotationally-Resolved Absorption Spectrum of Formaldehyde from 6547 to 7051 cm−1
We report new experimental data on the rotationally resolved room temperature
absorption spectrum of CH2O in the near infrared (NIR) region between 6804 and
7051 cm–1 (1470–1418 nm). Data have been obtained by cavity enhanced
absorption spectroscopy and complement the spectrum in the wavelength range
6547–6804 cm–1, obtained using virtually the same experimental set-up and
already published in an earlier publication (Staak et al., J. Mol. Spectrosc.
229 (2005) 115–121). Several vibrational combination bands occur in this
region and give rise to a congested spectrum and over 4500 lines with cross-
sections over 5 · 10–23 cm2 were observed. Recent experimental studies using
NIR absorption spectroscopy for quantifying CH2O in different chemical systems
indicate that the absorption cross-sections obtained by Staak et al. may have
been overestimated. The results of these experiments are reviewed here and a
recommendation for absolute absorption cross sections of CH2O in the NIR range
will be given. Absolute absorption cross-sections stated here are corrected by
the recommended factor
Following the excited state relaxation dynamics of indole and 5-hydroxyindole using time-resolved photoelectron spectroscopy
Time-resolved photoelectron spectroscopy was used to obtain new information about the dynamics of electronic relaxation in gas-phase indole and 5-hydroxyindole following UV excitation with femtosecond laser pulses centred at 249 nm and 273 nm. Our analysis of the data was supported by ab initio calculations at the coupled cluster and complete-active-space self-consistent-field levels. The optically bright 1La and 1Lb electronic states of 1\u3c0\u3c0* character and spectroscopically dark and dissociative 1\u3c0\u3c3* states were all found to play a role in the overall relaxation process. In both molecules we conclude that the initially excited 1La state decays non-adiabatically on a sub 100 fs timescale via two competing pathways, populating either the subsequently long-lived 1Lb state or the 1\u3c0\u3c3* state localised along the N-H coordinate, which exhibits a lifetime on the order of 1 ps. In the case of 5-hydroxyindole, we conclude that the 1\u3c0\u3c3* state localised along the O-H coordinate plays little or no role in the relaxation dynamics at the two excitation wavelengths studied.Peer reviewed: YesNRC publication: Ye
ANALISIS PENINGKATAN PRODUKTIVITAS DAN EFISIENSI SISTEM PRODUKSI SELANG HIDROLIK DENGAN METODE LINE BALANCING PT. HYDRO GEMILANG
Produktivitas dan efisiensi dari lintasan produksi merupakan dua hal yang sangat penting bagi perusahaan. Semakin tinggi produktivitas dan efisiensi dari lintasan produksi, maka semakin tinggilah jumlah produk yang dapat dihasilkan. Sebuah perusahaan selang hidrolik mengalami kesulitan dalam mengefisiensikan lintasan produksi dan memenuhi permintaan produksi mereka. Oleh karena itu, penelitian ini dilakukan untuk merancang lintasan produksi yang efisien bagi perusahaan agar mereka dapat meningkatkan produktivitas dan efisiensi sistem produksi. Pada penelitian ini penyeimbangan lintasan (line balancing) dilakukan dengan menggunakan dua metode, yaitu, metode Helgeson-Birnie dan metode Kilbridge-Wester. Berdasarkan hasil dari kedua metode tersebut, baik Helgeson-Birnie maupun Kilbridge-Wester, keduanya membentuk sebanyak 3 stasiun kerja untuk mengerjakan total 9 elemen kerja, dimana pada kondisi awal diperlukan 5 stasiun kerja. Kedua metode juga dapat meningkatkan efisiensi dan produktivitas kondisi awal, dimana kedua metode dapat meningkatkan efisiensi sebanyak 30,11% menjadi 71,25% dan meningkatkan produktivitas sebesar 3,91% dari jumlah produksi awal yang sebanyak 5850 unit
