Measuring Economic Integration in Developing Countries: The Case of Central America

This article builds a composite index, the Central American Integration Index (IIC-AMPI), to measure economic integration. This index utilises a robust methodology and conceptual framework. The study shows that IIC-AMPI is responsive to variable changes and resistant to outliers. The findings indicate that the Deep Integration Process initiative dominates the current integration trend, as seen in the regional average score from 2015 to 2017, aligning with Guatemala and Honduras. Nicaragua demonstrates the most consistent progress, while Panama lags behind. The evidence supports the Customs Union as Central America's future integration path, highlighting the index's ability to capture the dynamic reality of economic integration.     

试论我国中央集权——地方分权混合体制的合理性

不同国家在不同时期对于中央与地方关系的模式选择都会有所不同和有所侧重。我国采用中央集权——地方分权混合体制的关系模式,从市场经济的内在特性、中央与地方的政府职能配合、中央与地方的利益关系协调、集权制与分权制的优势互补来看,都具有深刻的合理性意义。     

DNA typing in populations of mule deer for forensic use in the Province of Alberta

The present study involves the development of forensic DNA typing tests and databases for mule deer in the Province of Alberta. Two multiplex PCR reactions interrogating 10 loci were used to analyze samples from three populations of mule deer. Additionally, an amelogenin based sex-typing marker was used to determine the gender of samples. Results show that the tests and databases are appropriate for use in forensic applications. Additionally, the results indicate that there is little population structure in mule deer in Alberta and that no changes to management of this game species are suggested.     

褥垫层厚度对带帽刚性桩性状的研究

对三个不同地点的带帽刚性桩复合地基工程进行试验监测,根据试验监测数据结果进行分析,可见褥垫层不同厚度对带帽刚性桩承载力和沉降变形的影响：设计褥垫层在某一合适的厚度,能有效降低桩身承载力,提高桩间土的承载力,使桩和桩间土合理共同承担荷载,降低复合地基沉降变形,减少地基对基础的应力集中,对工程实际有一定的指导意义.在试验分析的基础上,理论研究刚性桩带帽的条件,在褥垫层合适厚度下,单桩承载力、桩间土承载力、桩间土折减系数对刚性桩带帽都有影响,当条件符合时设置刚性桩带帽可以提高复合地基承载力,降低沉降变形.     

中美复合战略稳定关系:建构依据、基本框架与发展趋势

中美战略稳定关系已经超越经典战略稳定性，向着复合战略稳定关系的方向演化。建构中美复合战略稳定关系是稳定两国关系的客观需要。彼此战略竞争加剧给中美之间非均势核威慑基础上的战略稳定性带来负面影响。在美国提高核力量于国家安全战略中的地位、将核武器重新作为霸权工具的背景下，中美战略稳定性面临挑战。特朗普政府对中国挑起贸易争端，经贸关系在中美关系中的“稳定器”和“压舱石”作用减弱，建构中美复合战略稳定关系的必要性凸显。中美之间经济深度相互依存，在维护国际体系稳定方面具有共同利益，这为建构中美复合战略稳定关系奠定了坚实的基础。中美复合战略稳定关系框架包括建立在非均势核威慑基础上的战略稳定性、双方经济的深度相互依存、战略互信、双方对话交流与合作机制等四根支柱，其中以非均势核威慑基础上的战略稳定性为核心支柱。虽然中美战略互信存在短板，但随着中国战略核力量的进步、中美经济相互依存的继续维持和双方对话交流与合作机制的成熟和完善，中美复合战略稳定关系将不断巩固。     

Beyond the Z-score: A novel measure of bank stability for effective policymaking

This article looks beyond Z-score and proposes a novel methodological framework to build an all-encompassing indicator of bank stability for individual banks using the optimisation-based ‘benefit-of-the-doubt (BoD)’ approach. Unlike other available approaches, this approach is totally data-driven and generates endogenous weights to aggregate sub-indicators of bank stability and dimensions. Further, the final outcomes are not limited to a scalar measure of bank stability. The unique optimal weights offer valuable policy-relevant insights and highlight the most precarious areas of stability, which demand the immediate attention of the bank's management and the industry regulators for both micro-and macro-level policymaking. Using the data of Indian public sector banks operating in the year 2018, the study illustrates the proposed framework to obtain a holistic indicator of bank stability, defined on 14 ratio sub-indicators and 5 broad dimensions (soundness, asset quality, profitability, management efficiency, and liquidity) of bank stability.     

Catching the Bad Guy: Morphing Composite Faces Helps

Composite faces built by eyewitnesses commonly are poor likenesses of the target face. When there are multiple witnesses, however, an opportunity exists to morph the composites. Morphs were rated as more similar to the target face than were the mean ratings of the individual composites. However, as hypothesized, the morph also came to resemble non-target faces more than the individual composites did (a prototype effect). This prototype effect was so strong that the morphs resembled non-targets more than the individual composites resembled the targets. In addition, morphing composites produced an attractiveness bias, which made the morphing of composites less effective for less attractive targets. Even when the prototype effect and the attractiveness bias were controlled for, however, a true morph-superiority effect continued to exist. The author won the Psi Chi/APS Albert Bandura Graduate Research Award in 2005--2006 for this study.     

Heat Induced Changes to Dental Resin Composites: A Reference in Forensic Investigations?*

The objective was to investigate color change and surface damage in dental resin composites exposed to high temperatures over different time intervals for comparative purposes. Samples were prepared using two resins - Z100(R) (R1) and Charisma (R2), heated at the following temperatures: 200 degrees C, 400 degrees C, 600 degrees C, 1000 degrees C, for 15, 30 and 45 min (n = 104 for each resin sample). Color (DeltaE) and brightness (DeltaL) changes were analyzed by spectrophotometry using the CIE Lab system and surface changes by Scanning Electron Microscopy (SEM). R1 showed more intense color changes after heat exposure than R2. DeltaL values were found to be the best parameter for evaluation of light and color change. A biphasic pattern after thermal exposure was detected, from dark brown to light white. SEM showed more intense alterations in R2 than in R1. These results indicate that the parameters observed in both resins are useful as a guide in forensic analyses.

Artistic enhancement in the production of photo-fit likenesses: An examination of its effectiveness in leading to suspect identification

Following a crime, witnesses are often asked by the police to construct a Photo-FIT likeness of the suspect. However, previous laboratory research has indicated that the quality of the likenesses produced can be very poor. This study investigated whether the artistic enhancement of the basic Photo-FIT by a skilled operator using a variety of techniques influenced the quality of the Photo-FIT impression produced, and in turn increased the likelihood of correct recognition from the Photo-FIT. Six professional police Photo-FIT operators produced one basic Photo-FIT which was not artistically enhanced in any way and one Photo-FIT which had been artistically enhanced. These two types of Photo-FIT were given to 105 police recruits who were required to identify which face that Photo-FIT represented from a photographic lineup of 12 ‘suspect’ photographs. Composites which had been enhanced were significantly more successful in leading to a correct identification than were basic composites which had not been enhanced. The implications of these findings for police procedure and practice in the employment of commercial composite systems are discussed.
