The Latvian student corps and politics in the inter-war period of the twentieth century

Abstract

To date, Latvia's student corps have remained a neglected topic in the country's political history, notwithstanding the size of these organisations and the fact that they have been in existence for more than a century. Those accounts that do exist have for the most part been written by corps members themselves, and have not included any real analysis of the corps' interaction with society or their role in Latvian political life. A study of these issues opens up new avenues towards a better understanding of the activity and influence of interest groups in Latvian politics during the 1920s and 1930s. Unlike many other social organisations, the student corps (also including the alumni societies) are often seen as linked to the activity of the major parties, to the coup d'état of 1934 and to radical Latvian nationalism.     

The Effects of Juvenile Transfer to Criminal Court on Incarceration Decisions

The present study examined the effects of institutional pressures on homeland security preparedness among law enforcement agencies in Illinois. The data come from the Illinois Homeland Security Survey (IHSS). Specifically, the study employed three theories to explain homeland security preparedness: contingency theory, resource dependence theory, and institutional theory. We hypothesized that institutional pressures will lead to isomorphism as agencies attempt to conform to institutional expectations about appropriate activities in a homeland security era. To evaluate these theories and their impact on homeland security practices, the authors used confirmatory factor analysis. The IHSS data lend strong support to the application of organizational theory as a lens through which homeland security preparedness can be understood. Institutional pressures, such as professional and government publications, training, professional associations, and the actions of peer agencies, significantly influenced municipal and county agencies in Illinois. Funding, while often thought important to encourage preparedness, was not a significant predictor. The results of this analysis advance our understanding of homeland security preparedness via institutional theory by suggesting that the larger environment is salient.     

The transfer of touch DNA from hands to glass, fabric and wood

The transfer of DNA from hands to objects by holding or touching has been examined in the past. The main purpose of this study was to examine the variation in the amount of DNA transferred from hands to glass, fabric and wood. The study involved 300 volunteers (100 for glass, 100 for fabric and 100 for wood) 50% of which were male and 50% female. The volunteers held the material for 60 s. The DNA was recovered from the objects using a minitape lift, quantified using the Quantifiler kit assay, extracted using a ‘Qiagen^® QIAamp DNA mini kit’ and amplified using the AmpFlSTR^® SGM Plus™ Amplification Kit at 28 cycles. The results show that using ANOVA there was a significant difference (F = 8.2, p < 0.05) between the three object types in the amount of DNA recovered. In terms of DNA transfer and recovery, wood gave the best yield, followed by fabric and then glass. The likelihood of success of obtaining a profile indicative of the holder was approximately 9% for glass samples, 23% for fabric and 36% for wood. There was no significant difference between the amount of DNA transferred by male or female volunteers. In this study good shedder status, as defined by obtaining useful profiles of 6 or more alleles, is estimated at approximately 22% of the population. The phenomenon of secondary transfer was observed when mixed DNA profiles were obtained but the incidence was low at approximately 10% of the total number of samples. DNA profiles corresponding to more than one person were found on objects which had been touched by only one volunteer. Although secondary transfer is possible the profiles obtained from touched objects are more likely to be as a result of primary transfer rather than a secondary source.     

An innovative transfer DNA experimental design and qPCR assay to identify primary,secondary, and tertiary DNA transfer

“Touch DNA” is a form of trace DNA that is presumed to be deposited when an individual touches something and leaves behind DNA-containing skin cells, sweat, or other fluids. While touch DNA is often the result of direct contact (i.e., primary transfer), it can also be indirectly transferred between surfaces or individuals (e.g., secondary or tertiary transfer). Even experts cannot distinguish between different types of transfer and do not fully understand which variables affect direct versus indirect transfer or how often each type of transfer occurs. In this study, we utilize an innovative protocol that combines a paired male and female transfer DNA experimental design with an Amelogenin qPCR assay to generate data on primary, secondary, and tertiary DNA transfer. We report frequencies of indirect DNA transfer and also investigate the potential effects of participant age, self-identified ethnicity, and skin conditions on DNA transfer. Out of 22 experimental trials, we detected primary transfer (male + female) in 71% of trials, secondary DNA transfer in 50% of trials, and tertiary DNA transfer in 27% of trials. No significant associations were found between primary DNA transfer and age, self-identified ancestry, or skin conditions, however, all individuals with sloughing skin conditions demonstrated primary DNA transfer and we suggest this variable be explored in larger samples. These results contribute to a better understanding of the conditions under which secondary and tertiary DNA transfer occurs and can be used to propose realistic DNA transfer scenarios in court cases.     

A study of DNA transfers onto plastic packets placed in personal bags

The ability to detect low level DNA brings with it the uncertainty of whether the detected DNA is a result of transfer. To address this uncertainty, a simulation study was conducted in which a mock illicit drug packet was placed into the personal bags of individuals. When the average transit time of the packets was increased from around 2 h to more than 14 h, the percentage of the DNA profiles recovered from the packets which could be attributed to the individuals increased greatly from 5.3% to 48.6%. We found that drug packers who were poor shedders could not be included as contributors to the DNA profiles from the drug packets at all and there was a higher chance that individuals other than themselves could be included as contributors to the DNA profile recovered from drug packets. We also found that it was equally likely that the drug packers who had direct contact with the drug packets and bag owners who did not, could be included as contributors to the DNA profiles recovered from the packets. The results in this study highlight the importance of taking into consideration the transit time of drug packet, the shedder status of the alleged packer and the history of an item, when evaluating DNA evidence in the context of illicit drug activities.     

数字时代司法责任伦理之守正

在数字化浪潮下,司法活动呈现出"去责任化"的趋势,具体表现为责任感的缺失和责任推诿的加剧,因而亟待法学界对司法责任伦理予以革新。数字技术导致司法责任消解的机理是复杂和多元的,主要源于其兼具权威性与非权威性、确定性与不确定性、机械性与能动性等多重面孔。当前我国司法工作中的数字技术主要被应用于证据指引系统、风险评估工具、在线诉讼平台的开发等事项上,这些领域也是司法责任伦理冲突最为激烈的场域。数字时代应当坚守人本主义司法责任伦理,准确界定机器、技术人员、系统部署者与司法官的责任框架,在拥抱技术的同时树立科学的责任观,借助数字技术建立和完善符合时代特征的司法责任体系。     

The Relational Dynamics of World Bank Survey Missions

This article demonstrates that World Bank internal learning has led to significant changes in how the organization interacts with government officials through survey missions. Reviewing evidence of institutional learning and associated changes in practice and focusing on the relational modes being manifest in technical assistance, the article identifies three main phases of World Bank survey missions: general survey missions (1940s–1960s), country assistance strategies (1990s–2000s), and country partnership frameworks (2010s). Overall, World Bank reviews have repeatedly highlighted the importance of non-hierarchical interactions between Bank staff and country officials. In recent years, practice has begun to catch up with these operational insights.     

2,4,6-Tri(2′-pyridyl)-1,3,5-triazine for determination of iron(II), Iron(III), and total iron contents on human palms

When iron-based tools, such as knives or guns, are held, traces of iron can transfer to the skin. However, no previous studies have been published regarding the effect of the elapsed contact time on the transfer of iron species with different valences to the palm. Compared with 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine (PDT), 2,4,6-tri(2′-pyridyl)-1,3,5-triazine (TPTZ) was found to exhibit a higher sensitivity to iron(II) spectrophotometrically. This work employed 2,4,6-tri(2′-pyridyl)-1,3,5-triazine (TPTZ) and UV spectrophotometry to determine the amounts of iron(II), iron(III), and total iron transferred to human palms from iron tools. It was found that the palmar moisture level was an important factor in determining the amounts of total iron, including iron(II), transferred to the palm. For identical contact times, the amounts of total iron transferred to the palm was proportional to the palmar moisture, and the difference between the maximum and minimum amounts was 12 μg per hand. However, the amounts of iron(II) transferred to the palm gradually decreased over time for low palmar moisture levels, but steadily increased over time for high palmar moisture levels. Additionally, for average levels of palm moisture, the amounts of iron(II) and iron(III) transferred to the palm gradually decreased and increased, respectively, with longer contact times. Notably, this research could serve as a theoretical basis and guide for the detection of trace iron species with different valences on human palms for criminal investigations.     

A quantitative assessment of the extent and distribution of textile fibre transfer to persons involved in physical assault

Knowledge of the number of fibres transferred during a particular activity is essential for the interpretation of findings in similar criminal cases. In this regard, violent contacts and physical assaults still present a challenge, due to a lack of robust published data. Hereby, we present the outcome of an empirical study where different assault activities were simulated by a Jiu Jitsu team and participants were asked to play either the role of an aggressive ‘assailant’ or a defensive ‘victim’, wearing cotton garments (i.e., Gi’s). Four different scenarios were simulated in replicates (n = 5), each of them involving different intensity levels (low and high) and duration times (30 and 60 s). Results showed that approximately 1,000 to 44,000 fibres were cross-transferred between the participants’ garments, with noticeable differences between the different scenarios. These values were significantly larger than those published in previous studies and, therefore, suggested the possibility of a current underestimation of the number of fibres transferred in physical assaults. Furthermore, statistical analysis by ANOVA indicated that the all the variables tested (i.e., intensity level, duration time, and participants role) had a significant effect on the number of transferred fibres (p < 0.001) and, consequently, that some knowledge of the case circumstances may be important to make more educated estimations. This is the first time that such a methodology has been applied for the quantitative assessment of fibre transfer between participants in assault activities. Data are expected to help practitioners with the interpretation of findings in real casework and lead to a more robust evidential assessment.     

The final destination: Incorporating ‘Death by GPS’ into forensic and legal sciences

This article seeks to give visibility to a growing program: Motorists who set out for travel following directions from their GPS device and never return. These occurrences have gained the moniker ‘Death by GPS’. From giving incorrect directions, to taking motorists to isolated areas, to directing motorists into unsafe neighborhoods, GPS technology has led several people into catastrophic scenarios. This article is split into two sections. In the first section, the varying causes of Death by GPS are examined, alongside notable cases. In the second section, as Death by GPS is understudied in forensic science and legal spaces, the author explores the societal and scientific benefits of filling this gap. Relying on relevant collision figures, cultural trends, death science, legal studies, and ethics literature, this article produces groundwork on the growing issue of Death by GPS and identifies areas for future exploration.
