在新疆感悟中国新时代

2021年9月23—27日,应中国经济联络中心邀请,我作为团长率在华外国工商界代表团访问了新疆维吾尔自治区阿克苏、和田及乌鲁木齐三地。我这次访疆之旅最重要的收获,就是深化了对习近平新时代中国特色社会主义思想及其实践的认识。     

Australia's Indicator-Based Sustainability Assessments and Public Policy

Operationalising sustainability has proven difficult because the concept is ambiguous and fraught with contradictions. In response, sustainability indicator systems to characterise and measure sustainable development have been developed globally. The focus of this article is on how indicators function as an instrument of policy to enhance achievement of environmental and sustainability policy in Australia at national scale. In theory, by integrating information from the environmental, social and economic domains and then feeding knowledge to a wide range of policy sectors, sustainability indicator systems may facilitate cross-agency and -portfolio connectivity. Key characteristics of the various sustainability indicator systems developed to inform policy at the national level are described, noting the diverse approaches to indicator development in Australia. The structural relevance of indicator systems to the mechanisms of policy and institutions in Australia is discussed, and corresponding issues of institutional fit are analysed .     

Understanding the academic learning of university students using smartphone: Evidence from Pakistan

As the number of smartphone users have increased worldwide, research on the usage of the smartphone has received scholarly attention. However, different results were found in previous studies in different contexts. The main research question is whether adopting smartphones by students improve learning or generates interference. The purpose of this study is to examine the usage of smartphone among university students in Pakistan. Using a survey approach, data were collected from different universities/colleges of Karachi, Sindh, Pakistan. total, 585 entries was analyzed using SPSS 21.0 and AMOS 21.0 software. Results of analysis, validated most of the hypothesis showing the intention of Pakistani students towards smartphone usage for academic purpose. In addition, findings confirm that students' self‐efficacy related to a smartphone works as a moderating role of intention to use a smartphone for learning and actual usage of the smartphone. The current study has several implications in terms of smartphone usage and student academic performance. Limitations and implications of the study are also discussed in the last section.     

Money Laundering and Banking Secrecy in the Jordanian Legislation

Crimes targeting to damage the property of natural and legal individuals including states are in existence while the objective of people, groups and the entire organizations when committing crimes is illegal property gain in the structure of national, but also of global crime. However, they are insufficient hence they attempt to decriminalize money or other property earned in such manner, e.g. by inserting them into lawful operations and flows. Nonetheless, perpetrators of this kind of crime attempt to hide the right source of money or profit earned in such manner using all means possible. Banking secrecy is one of the main barriers that stand in front of anti-money laundering because it comprises of a barrier to access to bank deposits, and a protection for doubtful funds since it is one of the conventional rules pertinent to the work banks, where clients’ secrets and banking operations are saved by Bank’s commitment by law and custom unless there is provision in the law or in the agreement stating otherwise. This study is aimed at indicating the most significant stages and techniques of money laundering at banking institutions in Jordan and also discussing the function of the Jordanian banks in the light of the pertinent legislation.     

Sudden death due to congenital pericardial defect: an autopsy case

Pericardial defects are rare in childhood and outcome is usually benign. Patients may be asymptomatic, but chest pain, emboli, arrhythmia, and sudden death have been described in the literature. We report the case of a 12-year-old boy who suddenly died after mild exercise. A left-sided pericardial defect with a diameter of 8 cm was detected on medico-legal autopsy.     

Wavelet Analysis of Resultant Velocity Belonging to Genuine and Forged Signatures

This study presents a wavelet analysis of resultant velocity features belonging to genuine and forged groups of signature sample. Signatures of individuals were initially classified based on visual human perceptions of their relative sizes, complexities, and legibilities of the genuine counterparts. Then, the resultant velocity was extracted and modeled through wavelet analysis from each sample. The wavelet signal was decomposed into several layers based on maximum overlap discrete wavelet transform (MODWT). Next, the zero crossing rate features were calculated from all the high wavelet sub‐bands. A total of seven hypotheses were then tested using a two‐way ANOVA testing methodology. Of these, four hypotheses were conducted to test for significance differences between distributions. In addition, three hypotheses were run to provide test for interaction between two factors of signature authentication versus perceived classification. The results demonstrated that both feature distributions belonging to genuine and forged groups of samples cannot be distinguished by themselves. Instead, they were significantly different under the influence of two other inherent factors, namely perceived size and legibility. Such new findings are useful information particularly in providing bases for forensic justifications in establishing the authenticity of handwritten signature specimens.     

Lessons learned from inter-laboratory studies of carbon isotope analysis of honey

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C₄ plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.
