Limits of knowing or the consequences of difficult-access problems for multi-method research and public policy

How can scientists acquire an adequate level of knowledge on phenomena whose actors actively conceal their activities? Social phenomena such as terrorism, sects, corruption, Mafia organizations, drug dealers, or government intelligence agencies actively guard their secrecy, conceal their activities, decide who is allowed (not) to know, and have no interest in being observed or understood by others. The article discusses the consequences of researching difficult-access problems for doing multi-method research. In an ideal?Ctypical approach, we distinguish between social problems that can be easily accessed and those that are difficult to access or non-accessible. To distinguish the two, we define characteristics that eventually lead to the conclusion that scientific inquiry that follows the conventional paradigm of professionalism, transparency, and replicable research reaches its limits when confronted with the active resistance of phenomena that do not like to be observed, understood, or critically approached. From this flows, the necessity to think about interdisciplinary, collaborative, and investigative modes of research that come with various prices.     

Valuations – or How to Say the Unsayable

In this paper, the author revisits "the emotive theory of value" and argues that values are not entities but nothing other than "linguistic fictions". Accordingly, valuations—i.e., valuing actions—can be defined as approving or disapproving attitudes of a subject to some object. In this perspective, values cannot be true or false: What we can do is just compare them with regard to strength. As a consequence, value judgments are to be understood as sentences which are used either to say that a subject s values an object o positively or negatively, or to express (evince) a valuation. The author then shows some relations between normative and evaluative discourses. First, he claims that norms as well as valuations are not true or false. Second, he argues that both may be explained or justified, even if the former are usually justified teleologically whereas the latter are explained referring back to the subject's background and life-style. Third, he notes that a legal order originates from the fact that valuations "crystallize" into norms. Finally, the author examines some further questions related to his analysis. In particular, he argues that the different realms of values, e.g., morals, aesthetics, politics, etc., do not correspond to different evaluative attitudes, but to different phenomena and diverse spheres of human life.     

The problem of single parent/child paternity analysis--practical results involving 336 children and 348 unrelated men

In a certain amount of paternity investigations, only DNA from child and alleged father is analyzed, thus increasing the possibility of false paternity inclusions. The aim of this study was to determine how many wrong paternity inclusions could be detected in a rather small geographical area comparing empirical results from 336 children and 348 men (13-15 STRs were investigated per person). This comparison between each child and all unrelated men (i.e. all putative fathers from the other cases) with an especially designed computer program resulted in 116,004 man/child pairs. Less than three excluding STRs were found in 1666 child/unrelated man pairs (1.44% of the comparisons). At least one unrelated man with only two or less STR mismatches could be determined for 322 children (95.8% of all investigated children). In 26 comparisons no STR mismatches between a child and an unrelated man were detected, thus at least one and up to three "second father(s)" under 350 men could be found for 23 children, if the mother is excluded. Paternity probabilities between 95.475% and 99.996% were calculated. Our results underline the difficulties in motherless paternity cases using only STR analysis and advise great precaution in assigning verbal predicates such as "paternity proven" in those investigations.     

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.     

Alternative Ulster? Political Parties and the Non-constitutional Policy Space in Northern Ireland

This article uses data from a survey of the candidates in the 2003 Northern Ireland Assembly election to measure the policy positions of the Northern Irish political parties on scales that are the usual measurements of party policy in Western Europe, such as on economic and social issues, the European Union, morality issues, environmental issues and minority groups. These data were then used to test whether the Northern Ireland party system was conducive to integration or consociationalism, which is the current debate on conflict resolution in Northern Ireland. It argues that this debate has been under-theorised and that empirical data can be used to test the likelihood of either scenario. It concludes that, in most aspects, the Northern Ireland party system tends towards the consociational scenario but there are, nevertheless, aspects which suggest that an integrationist scenario could be produced in the long term.     

Institutional Actors in the Brazilian Amazon: Possibilities for NGO and Public Sector Collaboration in Rural Agriculture

Public sector institutions in Amazonian Brazil are experiencing structural reforms, budget cuts, and overburdened missions. Services needed to support appropriate resource use practices by rural farmers are gradually being provided by NGOs where the public sector has failed to provide them. But local NGOs are institutionally weak, and their activities are poorly coordinated with other regional service providers. This article analyzes three models for NGO organization and partnership that were designed outside of the Amazon region, and tests their applicability to the small-farming sector in Pará State in the eastern Brazilian Amazon. With some adaptation, these models can effectively help coordinate three overarching needs in the region: institutional strengthening, regional planning, and improving program effectiveness and efficiency.     

Co-occurrence and Correlates of Posttraumatic Stress Disorder and Major Depression in Physically Abused Women

Ninety two women presenting for treatment for marital problems and who were physically victimized by their spouses (e.g., pushing, shoving, punching) within the past year participated in this study. There were three study objectives: (1) document rates and co-occurrence of posttraumatic stress disorder (PTSD) and Major Depressive Disorder (MDD), (2) identify predictors of PTSD and depression symptom frequency/severity, and (3) systematically evaluate disorder-specific group differences in marital- and marital violence-related factors. Within the month prior to assessment, 29.8% of the sample met diagnostic criteria for PTSD and 32% for MDD. MDD and PTSD were significantly, but moderately, correlated at both the symptom and diagnosis levels. However, PTSD symptom frequency and depression symptom severity were predicted by different marital- and marital violence-related factors. PTSD symptoms were predicted by spouse's dominance/isolation tactics and intensity of husband-to-wife physical aggression while depressive symptoms were predicted by marital discord and intensity of husband-to-wife physical aggression. Comorbid women and those with PTSD only reported significantly more spousal fear and husband-to-wife physical aggression than those with MDD only or neither disorder. No group differences were found on rate of marital discord or spouse's controlling/isolating tactics. Results are discussed in terms of theoretical and treatment implications for abused women seeking treatment for marital conflict.     

Predictors of Physical Competence in Adolescent Girls

Physical competence, comprising athletic competence and physical appearance competence, is positively related to feelings of self-worth in adolescent girls. This study compared the relationships of psychological, physiological, and maturational constructs with perceived physical competence in adolescent girls. Perceived physical appearance and perceived athletic competence, peer acceptance, body weight, body mass index (BMI), aerobic fitness (VO₂max), physical activity level, and menarcheal status were assessed. Global self-worth was highly correlated with peer acceptance, perceived physical appearance, and perceived athletic competence in this sample. Regression analyses indicated that peer acceptance was the best predictor of perceived physical competence. Additional predictors of perceived physical appearance and athletic competence are discussed. Results suggest that postmenarcheal and larger girls may be at risk for low perceptions of physical competence. Enhancing competence feelings among adolescent girls may be accomplished by emphasizing friendship and social interaction within physical activity.
