Time-lapse resistivity surveys over simulated clandestine graves

The aim of this study was to develop a better understanding of how electrical resistivity surveys can be used to locate clandestine graves. Resistivity surveys were conducted regularly over three simulated clandestine graves containing a pig cadaver, no cadaver and a pig cadaver wrapped in tarpaulin, respectively. Additionally, soil and groundwater samples were collected from two more simulated graves outside the survey area. The grave containing a pig cadaver was detectable from a low resistivity anomaly in the survey data. Groundwater data suggest that the resistivity anomaly associated with the surveyed pig grave was caused by a localised increase in groundwater conductivity. Wrapping a cadaver was found to initially change the resistivity response of a grave to a high resistivity anomaly. Resistivity surveys did not detect the disturbed soil in the grave that did not contain a cadaver. Although soil samples showed grave soil to be more porous than undisturbed soil, the lack of response from the grave that did not contain a cadaver suggests that disturbed soil was not responsible for the resistivity anomalies observed in this study. Resistivity surveys successfully detected all graves containing cadavers throughout the study, whilst also showing the potential to eliminate the need for mass excavation in a genuine search.     

Genetic variability of RyR2 and CASQ2 genes in an Asian population

We analyzed the coding regions of the cardiac calcium-handling genes, ryanodine receptor 2 (RyR2) and calsequestrin 2 (CASQ2) for genetic variants in a healthy Chinese population (n = 95) and in a cohort of 28 sudden unexplained death victims. Mutations in RyR2 and CASQ2 have been shown to alter calcium homeostasis during excitation–contraction coupling and predispose individuals to fatal cardiac arrhythmias. The genetic screening was accomplished by denaturing high-performance liquid chromatography and DNA sequencing methods. Genetic analysis revealed the following non-synonymous genetic variations: two reported RyR2 polymorphisms; 5654G>A (G1885E) and 5656G>A (G1886S), two reported CASQ2 polymorphisms; 196A>G (T66A) and 226G>A (V76M) and one novel CASQ2 mutation; 529G>C (E177Q). The functional significance of the novel CASQ2 mutation has not been evaluated and characterized. This study shows that multiple genetic variations of the RyR2 and CASQ2 genes exist in the two study populations. The inter-individual genetic variability may underlie the different susceptibility of individuals to developing ventricular tachycardia. The research results will be valuable for which future work involving clinical and forensic samples can be based upon to distinguish potential disease-associated mutations from common polymorphisms.     

Forensic utility of the mitochondrial hypervariable region 1 of domestic dogs, in conjunction with breed and geographic information

The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples.     

Planning, Performance And Public Services

The policies of the Labour government in the UK place renewed emphasis on rational planning in the public sector. The government’s assumption is that this approach to decision making will lead to improvements in performance. Although the theoretical costs and benefits of rational planning have been widely debated in the public administration literature, no systematic empirical research on the impact of planning on the performance of public organizations has been conducted. By contrast, the relationship between rational planning and the success of private firms has been investigated extensively. A meta‐analysis and critical review of this evidence suggests that planning is generally associated with superior performance. However, important questions remain unresolved. For example, under what circumstances does planning work best, and which elements of planning are most important? Therefore, although it may be appropriate to encourage public agencies to consider carefully the potential benefits of planning, rational processes should not be imposed upon them.     

The Enemy Within: Intragovernmental Politics and Organizational Failure in Greek Privatization

Mainstream approaches explain privatization policy failure by taking account of the surrounding sociopolitical and economic context. This article examines the unsuccessful Greek privatization over the first half of the 1990s by following an alternative approach. It looks at the obstacles originating from intragovernmental politics and the state organizational structures and resources. Contrary to what the British or French experience would suggest, the adoption of a statist, impositional policy-making strategy in the Greek case failed to achieve policy effectiveness. Indeed, it probably ended up accelerating policy failure. The employment of statism as a policy-making strategy was undermined by the structural weaknesses of the state.     

CAREFUL COMMITMENT

New avenues to be explored for Belt and Road cooperation At the beginning of 2021,the situation looks better in China and the rest of the world.China is striving to maintain its success in eliminating COVID-19 cases domestically and fostering immunity for its 1.4-billion population.The more the vaccination process gains ground,the more it is likely that lives will return to normalcy.     

Institutional isomorphism,negativity bias and performance information use by politicians: A survey experiment

New Public Management popularized performance measurement in public organizations. Underlying performance measurement's popularity is the assumption that it injects performance information (PI) into decision-making, thus rationalizing the ensuing decisions. Despite its popularity, performance measurement is criticized. In part, this criticism results from the limited knowledge of the conditions under which PI is purposefully used by politicians. We conducted a survey experiment based on real PI with 1,240 politicians. We hypothesized that PI has a positive impact on performance information use (PIU) when PI is benchmarked with coercive, mimetic or normative pressures. Moreover, due to negativity bias we expected this positive impact to be stronger when PI signals low performance. We found that normative pressures had a positive impact on actual PIU while coercive pressures positively affected intended PIU. Negativity bias is only relevant when linked to coercive pressures and intended PIU for analysing the organization's finances.
