Social welfare functions when preferences are convex,strictly monotonic,and continuous

The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R ₊ ⁿ , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship.     

Microbial metagenome profiling using amplicon length heterogeneity-polymerase chain reaction proves more effective than elemental analysis in discriminating soil specimens

The combination of soil's ubiquity and its intrinsic abiotic and biotic information can contribute greatly to the forensic field. Although there are physical and chemical characterization methods of soil comparison for forensic purposes, these require a level of expertise not always encountered in crime laboratories. We hypothesized that soil microbial community profiling could be used to discriminate between soil types by providing biological fingerprints that confer uniqueness. Three of the six Miami-Dade soil types were randomly selected and sampled. We compared the microbial metagenome profiles generated using amplicon length heterogeneity-polymerase chain reaction analysis of the 16S rRNA genes with inductively coupled plasma optical emission spectroscopy analysis of 13 elements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Si, and Zn) that are commonly encountered in soils. Bray-Curtis similarity index and analysis of similarity were performed on all data to establish differences within sites, among sites, and across two seasons. These data matrices were used to group samples that shared similar community patterns using nonmetric multidimensional scaling analysis. We concluded that while chemical characterization could provide some differentiation between soils, microbial metagenome profiling was better able to discriminate between the soil types and had a high degree of reproducibility, therefore proving to be a potential tool for forensic soil comparisons.     

Right‐wing terrorism in a comparative perspective: The case of split delegitimization

The purpose of this article is to identify the distinctive features of right‐wing terrorism and to develop an analytical typology of particularistic terrorist organizations. The article is based on the conceptual framework of the process of delegitimization developed earlier by this author. It argues that right‐wing radicals usually reach terrorism through a trajectory of split delegitimization, which implies a primary conflict with an ‘inferior’ community and a secondary conflict with the government. Six sub‐types of right‐wing terrorism are identified: revolutionary terrorism, reactive terrorism, vigilante terrorism, racist terrorism, millenarian terrorism and youth counterculture terrorism.     

Old (Molotov) cocktails in new bottles? “Price-tag” and settler violence in Israel and the West Bank

In the early morning of July 31, 2015, masked attackers threw firebombs into two Palestinian homes in the West Bank village of Duma, south of Nablus, killing three Palestinian civilians. Contrary to claims by Israeli and Palestinian politicians, this attack was neither an isolated anomaly nor just another incident of settler violence. Instead, it was the latest attack in an important but largely unknown phenomenon called “price-tag,” in which a loosely connected group of young Israelis called “hilltop youth” burn Palestinian mosques and destroy property in hundreds of attacks accompanied by threatening graffiti that references Israeli settlers, outposts, and anti-Arab slogans. Using an original dataset of price-tag incidents and interviews with key actors, we demonstrate that the perpetrators, targets, and strategies of price-tag are different than previous patterns of settler violence. Whereas previous settlers saw the Israeli state as legitimate and largely decided to cooperate with it, the hilltop youth have decided to confront it by using price-tag attacks to deter settlement withdrawals and chain-gang the state into a conflict with the Palestinians. This analysis of the strategic logic of price-tag reveals its potential to shift the political landscape within and between Israelis and Palestinians.     

Recovery and detection of urea nitrate in traces

Urea nitrate (uronium nitrate, UN) is a powerful improvised explosive, frequently used by terrorists in the Israeli arena. It was also used in the first World Trade Center bombing in New York in February 1993. It is difficult to identify UN in postexplosion debris, because in the presence of water it readily decomposes to its original components, urea and nitric acid. A method for the recovery and detection of urea nitrate in traces is described. The residues are extracted with hot acetone, and the extract chromatographed on chromosorb G-HP. The eluent is analyzed by liquid chromatography mass spectrometry using atmospheric pressure chemical ionization (APCI). By applying this technique, we were able to identify urea nitrate in actual exhibits. It was found that UN can be also formed during the analytical procedure, by certain combinations of urea, nitrate ions, and a source of protons and, hence, the presence of the characteristic adduct ion does not necessarily indicate an "authentic" urea nitrate. Several solutions are suggested to overcome this ambiguity.     

Compensation Schemes and Dispute Resolution Mechanisms: Beyond the Obvious

Because compensation and dispute resolution lie at the core of most resettlement proposals, this panel had two main objectives: to get an accurate grasp of the current Israeli approach to these challenges and to glean insights from relevant experiences in other settings. Before reading our panelists' presentations, one might be forgiven for reasonably thinking that "compensation equals cash" and "dispute resolution equals court." As our panelists discussed, however, such a straightforward view is simply inadequate to the needs of the resettlement problem — a much richer view of compensation and dispute resolution is required.     

A novel method for the analysis of discharged smokeless powder residues

A novel method for the estimation of intermediate-long firing distance range is proposed. The method is based on the characterization and chemical analysis of the smokeless powder particles on the target. An adhesive lifter is applied to collect the suspected gunshot residues (GSRs) from the surface of an object, and a Modified Griess Test (MGT) is carried out after alkaline hydrolysis on the adhesive lifter. Visualized particles are removed from the adhesive lifter under a microscope. Two systems are used for the analysis of organic discharge residues from the smokeless powder: (1) gas chromatography/thermal energy analysis (GC/TEA) for the analysis of nitroglycerine (NG) and 2,4-dinitrotoluene (2,4-DNT), (2) gas chromatography/mass spectrometry (GC/MS) for the identification of organic components such as DNT, NG, and some stabilizers. By using this procedure and confirming that the suspected particles are indeed GSR, one can estimate the intermediate-long firing distance of c. 0.75-3 m in the presence of very few particles and provide information for the classification of ammunition type in casework.     

A possible source of reference DNA from archived treated adhesive lifters

During the course of a double murder trial, it became apparent that the two adhesive lifters from the two cadavers had been mislabeled before being presented in court. The question was raised whether DNA testing from the biological material remaining attached to the lifters could resolve this mix-up. In fatal shooting cases where a bullet has been fired through a body surface, an adhesive lifter is applied directly to the entrance wound. The total nitrite residues, as well as biological material surrounding the wound (blood, hair, tissue) are transferred to the adhesive lifter. The nitrite residues are used for estimating firing distance. In a worst-case scenario, the biological material on the lifter may be the only remaining reference material from a victim. In this paper, we examined whether the biological material retrieved from adhesive lifters could be used for DNA typing after the lifters had been treated for GSR pattern. In as much as the biological material found on the lifters can be typed and profiled following physical and chemical treatment, we submit that archived adhesive lifters can be used as a future source of reference DNA from cadavers where no other sample is available.     

The Three Tensions of Investigating Intelligence Failures

This paper offers a framework for analyzing governmental inquiries into intelligence failures. The paper argues that all investigations face three inherent tensions over their timing, purpose, and process. The benefits and disadvantages of conducting inquiries immediately after the intelligence failure or years later, engaging in investigations designed to ascribe blame or find solutions to endemic intelligence problems, and conducting adversarial, legal-style investigations or collaborative inquiries, are all discussed. In many cases, but not always, the two first tensions are exacerbated by the politicization of the inquiry. Using examples from governmental inquiries around the world, the paper investigates each tension and offers some strategies for mitigating them.
