Discrimination of pencil markings on paper using elemental analysis: an initial investigation

The characterisation and comparison of pencil markings on paper is an area of questioned document analysis that has previously not received much attention. Despite this, there would be value in an examiner being able to analyse two pencil markings and coming to a conclusion about whether they were from a similar or different source. Previous studies have analysed raw materials and bulk pencil cores for purposes of characterisation and differentiation, but to date, no studies have successfully analysed pencil markings non-destructively off a paper substrate. In this work, pencils from a number of manufacturers were analysed by inductively coupled plasma mass spectrometry (ICP-MS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Analysis of data using multivariate techniques (principal component analysis), showed that ToF-SIMS can successfully be used to analyse such pencil markings to deduce whether two markings can be differentiated, in terms of inorganic elemental composition. It was possible to discriminate between pencil markings from different manufacturers, and it was also indicated that pencils from the same manufacturer, but discrete batches, can be significantly different.     

The Process of Leaving an Abusive Relationship: The Role of Risk Assessments and Decision-Certainty

Seventy female residents of an urban domestic violence shelter were interviewed to examine a series of hypotheses concerning two factors relevant to the process of leaving an abusive relationship: risk assessments and decision-certainty. Participants' subjective estimates of their own risk of returning to the batterer were examined relative to their perceptions of the likelihood that most battered women will return to the batterer, their certainty regarding the decision to leave the batterer, and their status on known risk factors for returning to an abusive relationship. As hypothesized, battered women's perceptions of personal risk for returning to the batterer were biased by unrealistic optimism; specifically, personal risk was estimated as significantly lower than the risk of most battered women and was not correlated with actual risk factors. Further, the magnitude of the optimistic bias was significantly greater among women expressing high certainty about their decision to leave than among women who expressed less certainty. The clinical implications of these findings are discussed.     

Fiscal Federalism for Emerging Economies: Lessons from Switzerland?

Switzerland is one of the most non-centralized countries inthe world. A groining literature is examining the economic effectsof tax competition between the 26 Swiss cantons. Despite therelative success of Swiss federalism, most federal countriesfollow the principles of coordinated rather than competitivefederalism. We identify the institutional preconditions forwell-functioning competitive federalism in Switzerland. Thesecond part deals with the applicability of the Swiss experiencefor emerging economies in Latin America. The analysis recognizesthat most institutions identified to be crucial in the Swisscase are missing in Latin America. This leads to the policyconclusion that competitive federalism can only produce itspositive effects under certain institutional circumstances.These circumstances are often not considered when introducinglax competition in emerging economies.

Predictors of Euroscepticism in six Western Balkan countries

ABSTRACT

Based on a combination of national representative surveys and semi-structured interviews conducted in six Western Balkan countries, the study represents a pioneering attempt at a systematic, comparative analysis of Euroscepticism in the Western Balkans. By employing a theoretical framework that tests the effects of utilitarian, political and cultural factors, the study identifies and interprets the strongest socio-demographical and attitudinal predictors of Euroscepticism. The study demonstrates that all three theoretical models have some explanatory power regarding Eurosceptical attitudes in the Western Balkans, albeit to different degrees. While utilitarian predictors have limited effects, domestic proxies and especially cultural factors such as traditional values, authoritarian orientations and particularly religious affiliation appear as the strongest predictors of Euroscepticism.     

Migrants and their families in the home country: a bi-directional influence on voting behaviour

ABSTRACT

The voting behaviour of migrants has been studied extensively but limited attention has been paid to how the discussion with families in the home country can be important. This article analyzes under what circumstances migrants influence or are influenced by their families in voting decisions. The analysis uses individual-level data from a survey conducted in 2018 on a sample of 1,839 Romanian migrants. The results indicate that most migrants are not engaged in acts of persuasion about voting. Those who influence their families have a direct interest in the election results, are informed about what happens in the country and are politically active. The migrants who are influenced by their families have limited experience in the countries of residence and strong ties to their home country.
