Mole guns in Turkey in 2003-2005

This study describes the frequency of mole guns in Turkey by examining the cases sent to the Council of Forensic Medicine of Turkey between 2003 and 2005. In total, 11 mole guns were examined. Mole guns are manufactured to be used as a trap against detrimental animals. Although they are not meant to be used as a firearm, they are able to cause death. Mole guns appearing in regular casework were evaluated in terms of type of the gun, number of barrels, size and caliber, rifling, design, mechanism, fitness for use, legality, and geographical distribution. Ninety-one percent of the guns were 12 gauge. Most commonly they originate from Inner Anatolia. Mole guns are typically handmade. Some examples of injuries and deaths caused by mole guns are also offered.     

Body Height Estimation from Head and Face Dimensions: A Different Method*

Abstract: As there are cases brought for forensic examination where only the craniofacial region is available, estimation of stature from craniofacial dimensions is without doubt important in forensic cases. The study presented here attempts to estimate stature from craniofacial dimensions in the Turkish population. In the second phase of the study, the correlations between craniofacial dimensions and stature were also evaluated according to different head and face types. All measurements were taken from 286 healthy males with a mean age of 22.71 ± 4.86 years. The sample was then reclassified according to different head and face indexes. For the whole sample, correlation coefficients were low, changing only between 0.012 and 0.229. Thus, no significant increase in correlation coefficients was observed after the samples had been reevaluated according to different head and face types. As a conclusion, craniofacial dimensions are not good predictors for body height for the Turkish population.     

Social Capital and Hygiene Practices among the Extreme Poor in Rural Bangladesh

We investigate the effect of social capital on hygiene practices pertaining to lives of the extreme poor in rural Bangladesh. Analysing a unique survey dataset for 5,600 extreme poor households, we document a significant positive effect of social capital on sanitary latrine use and wearing shoes/sandals at home for hygiene. We account for the endogeneity of social capital by instrumental variable estimation. Our findings emphasise the role of social capital in preventing common diseases through improving hygiene practices for the extreme poor, who usually lack access to medical services in the event of illness, which has important policy implications.     

Implementing the Borda outcome via truncated scoring rules: a computational study

This study is an attempt to empirically understand the likelihood of choosing the Borda outcome through a truncated scoring rule when n voters are asked to report only part of their linear preferences over m alternatives. We run Monte Carlo simulations through a grid search algorithm as we employ an impartial culture model to sample voters’ preferences. Given the range of parameter values we consider, we report the truncated scoring rules that maximize the likelihood of implementing the Borda outcome and how the maximum likelihood changes with m and n. We also present our results on the relative performances of some popular truncated voting rules, such as plurality and approval voting, in implementing the Borda outcome and demonstrate that two-level approval voting performs significantly better than the plurality rule. Moreover, we propose the expected Borda rule as a good proxy for the best implementor of the Borda rule among all truncated rules.     

Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger

The Meisenheimer anions formed from TNT in KOH solutions in alcohol or acetone were used in screening tests for TNT among possible nitro-explosives. The same reaction was used for the spectrophotometric assay of TNT in soil by CRREL (Cold Regions Research & Engineering Laboratory of the U.S. Army) method, also known as Jenkins' method, but the color stability was too dependent on the solution composition and the water tolerance was low, necessitating complete drying of soil samples (which may cause partial analyte decomposition) prior to analysis. This study reports the development of a colorimetric method based on the solid phase extraction (SPE) of the Meisenheimer anion formed from TNT and aqueous NaOH into a strongly basic anion exchange resin Dowex 1-X8 (OH(-) form). The orange-red color that developed both in the solid resin and solution phases was persistent for at least 1h. The resin was let to swell in alcohol, washed first with 1M aqueous NaOH, and then with H(2)O before use. To 5 mL of 4-400 ppm TNT solutions in 1:1 (v/v) acetone-water, 0.5 mL of 5% NaOH was added, diluted to 50 mL with 1:1 acetone-water, and the resulting solutions (containing the orange-red Meisenheimer anion of TNT) were agitated at room temperature with 0.9 g resin for < or =50 min. TNT exhibited a reasonably constant distribution coefficient between the resin and aqueous phases. The absorbance of the filtered solutions was measured against a reagent blank at 500nm. The TNT-loaded resins were regenerated with 1M HCl containing sodium sulfite. The calibration line of filtrate absorbance versus analytical concentration was linear over two orders of magnitude between 0.4 and 40 ppm TNT in final solution. Unlike Jenkins' method, the method was tolerant to 100-fold (by mass) of common soil anions like sulfate, nitrate, and chloride. The basic advantages of the developed colorimetric method over the similar CRREL/Jenkins' method may be summarized as color stability, water and common ion tolerance, lowering of the LOD, and widening of the linear range. As opposed to Jenkins' method, the charge-transfer bands characteristic to colorimetric detection were not obscured by the presence of water. The method is suitable for on-site applications, because the color developed in heterogenous solution was stabilized, and the method can be easily practiced with a portable colorimeter to large numbers of samples.     

Midline facial soft tissue thickness database of Turkish population: MRI study

Facial reconstruction is the approximation of an antemortem face from human skeletal remains. Since the nineteenth century, several methods have been developed for reconstruction of the face; all of them require the measurement of average tissue thicknesses at various points on the face. To our knowledge, there are no publications on soft tissue thickness in the Turkish population. In addition, there are few publications on the value of magnetic resonance imaging (MRI) in measuring soft tissue thickness for forensic sciences. The aim of this study was to create a reference database of facial tissue thickness in the Turkish population, and to present data illustrating the successful use of MRI for this purpose. The study included 161 patients (79 males and 82 females) between the ages of 18 and 78 who had undergone brain MRI in our radiology clinic, and showed no sign of maxillofacial pathology. Measurements were taken at 9 points at the midline; glabella, nasion, end of nasals, mid-philtrum, upper lip margin, lower lip margin, chin-lip fold, mental eminence, and beneath chin points. The mean values for these points in the patient sample population were determined, and differences related to age, sex, and body mass index (BMI) were calculated. The values were then compared to the findings of the Manhein study.     

The Oslo Talks: Revealing the Turkish Government's Secret Negotiations with the PKK

This article explores the extent to which the secret talks influenced the path of official negotiations toward ending Turkey's Kurdish conflict, which the scholarly literature has yet to assess. Utilizing interviews with key political actors, this article aims to close this gap by assessing the Oslo talks (2006–2011) as the most comprehensive secret contact between the Turkish government and Kurdistan Workers' Party. It demonstrates that the secret track is not merely a “pre-negotiation” stage aimed at de-escalating the violent conflict ahead of official talks, but also a crucial part of the negotiation stage aimed at establishing a final political agreement.
