Concepts in Political Science

A concept is the name of any general element in one's experience, and, consequently, in social science all conclusions are based on concepts. The main object of this article is to indicate the existence of a logical gulf between the concept as an object of analysis made by social science and the concept as a means to accomplish the analysis     

On non-invasive 2D and 3D Chromatic White Light image sensors for age determination of latent fingerprints

The feasibility of 2D-intensity and 3D-topography images from a non-invasive Chromatic White Light (CWL) sensor for the age determination of latent fingerprints is investigated. The proposed method might provide the means to solve the so far unresolved issue of determining a fingerprints age in forensics. Conducting numerous experiments for an indoor crime scene using selected surfaces, different influences on the aging of fingerprints are investigated and the resulting aging variability is determined in terms of inter-person, intra-person, inter-finger and intra-finger variation. Main influence factors are shown to be the sweat composition, temperature, humidity, wind, UV-radiation, surface type, contamination of the finger with water-containing substances, resolution and measured area size, whereas contact time, contact pressure and smearing of the print seem to be of minor importance. Such influences lead to a certain experimental variability in inter-person and intra-person variation, which is higher than the inter-finger and intra-finger variation. Comparing the aging behavior of 17 different features using 1490 time series with a total of 41,520 fingerprint images, the great potential of the CWL technique in combination with the binary pixel feature from prior work is shown. Performing three different experiments for the classification of fingerprints into the two time classes [0, 5h] and [5, 24h], a maximum classification performance of 79.29% (kappa=0.46) is achieved for a general case, which is further improved for special cases. The statistical significance of the two best-performing features (both binary pixel versions based on 2D-intensity images) is manually shown and a feature fusion is performed, highlighting the strong dependency of the features on each other. It is concluded that such method might be combined with additional capturing devices, such as microscopes or spectroscopes, to a very promising age estimation scheme.     

Social equity and LGBTQ populations in African public administration: A macro- and micro-approach

How do public administrators understand social equity toward lesbian, gay, and bisexual (LGB) individuals and communities? To better understand social equity, this study uses data on the views of public and nonprofit administrators in 33 countries in Africa on LGB people. Based on these responses, we gain a better understanding of homophobia in public administrators. Furthermore, this data helps public administrators to explore how social equity might look differently to public and nonprofit administrators in different countries. Building on this foundation, this study proposes understanding social equity from both a Micro (individual) and a Macro (cultural)-perspective. Bringing in this micro- and macro-perspective can help public administrators and researchers to discuss how individuals and organizations identify “vulnerable” populations and appropriate ways to support vulnerable groups.     

In the aftermath of disclosing child sexual abuse: consequences,needs, and wishes

Experiencing child sexual abuse (CSA) can have enormous consequences for the victims. However, reporting rates are comparably low. Thus, it is essential to consider the wishes and needs of disclosing CSA victims in order to develop measures that can improve the disclosure and reporting of CSA. We analysed data of a subsample of n?=?394 victims of contact CSA from a representative victim survey (N?=?11,428) conducted by the Criminological Research Institute of Lower Saxony, Germany, in 2011. Overall, 76% of the victims disclosed their CSA experience to somebody. However, only 14% of the cases were made known to law enforcement agencies. Of the disclosing victims, only one-third was believed and 43% reported that the disclosure led to no further consequences. Overall, being believed as well as supported by the victims’ family proved to be crucial. Implications are discussed against the background of previous research.     

The counselor's trauma as counseling motivation: vulnerability or stress inoculation?

Should counselors with interpersonal trauma histories work with similarly traumatized clients? How does the work affect them? Current research is inconsistent. This study examines 101 sexual assault and domestic violence counselors' recalled motivations for trauma work, their reported subjective personal changes, and their secondary and vicarious trauma symptoms and burnout. Counselors motivated by interpersonal trauma report both more symptoms and positive changes (including dealing with their own trauma). Those seeking personal meaning report becoming more hypervigilant and self-isolating. Those saying they learned from clients rate symptoms lower, suggesting stress inoculation. Supervisors of trauma counselors should facilitate learning from clients separately from processing the counselor's trauma.
