中西方动机思想的多维探究与运用

动机在教学中的重要性不言而喻,关于动机的探讨也是古今中外早已有之。从中国先秦时代孔孟的论述,到近代西方系统、完整的介绍、阐释,动机这一教学成效中极其关键的因素,也越来越被广大学者接受、认可,并发挥着日渐突出的作用。我们试从中国古代先秦思想和西方人本主义心理学入手,初步探讨动机的成因以及作用机制,并结合当今语文学习做实际和细致的阐述。     

MENTORS AND CRIMINAL ACHIEVEMENT*

Much of the research focusing on conventional occupations concludes that mentored individuals are more successful in their careers than those who are not mentored. Early research in criminology made a similar claim. Yet contemporary criminology has all but ignored mentors. We investigate this oversight, drawing on Sutherland's insights on tutelage and criminal maturation and incorporating ideas on human and social capital. We argue that mentors play a key role in their protégés' criminal achievements and examine this hypothesis with data from a recent survey of incarcerated adult male offenders in the Canadian province of Quebec. In this sample, a substantial proportion of respondents reported the presence of an influential individual in their lives who introduced them to a criminal milieu and whom they explicitly regarded as a mentor. After studying the attributes of offenders and their mentors, we develop a causal framework that positions criminal mentor presence within a pathway that leads to greater benefits and lower costs from crime.     

THE DEVELOPMENT OF SELF‐CONTROL: EXAMINING SELF‐CONTROL THEORY'S STABILITY THESIS*

Research on self‐control theory consistently supports its central prediction that low self‐control significantly affects crime. The theory includes other predictions, however, that have received far less scrutiny. Among these is the argument that self‐control is developed early in childhood and that individual differences emerging then persist over time. The purpose of this study is to provide a rigorous test of the stability thesis. First, we examine the extent of stability and change in self‐control for a national sample of U.S. children age 7 to age 15. Second, we consider whether parenting continues to affect self‐control during adolescence—a period after the point at which self‐control differences should be fixed. The analysis revealed strong absolute and relative stability of self‐control for more than 80 percent of the sample, and this stability emerged in large part as early as age 7. Contradicting the theory was a smaller portion of respondents (roughly 16 percent) who experienced substantial absolute and relative changes in self‐control even after the age of 10. Moreover, parental socialization continued to affect self‐control during adolescence, even after accounting for both prior self‐control and exposure to parental socialization.

论拒绝强迫自证其罪规则——以此为突破口设置我国沉默权制度

沉默权制度一直是我国刑事诉讼领域炙手可热的话题,然而当前是否已经具备了引进沉默权的条件,在我国目前的“本土”环境下其能否有效运行,还需进行辩证的分析。如沉默权所要求的制度条件,沉默权的引进应该暂缓,沉默权与拒绝自证其罪的关系。同时提出了以拒绝自证其罪的角度设置我国的沉默权制度。     

Detection of visible and latent fingerprints using micro-X-ray fluorescence elemental imaging

Using micro-X-ray fluorescence (MXRF), a novel means of detecting fingerprints was examined in which the prints were imaged based on their elemental composition. MXRF is a nondestructive technique. Although this method requires a priori knowledge about the approximate location of a print, it offers a new and complementary means for detecting fingerprints that are also left pristine for further analysis (including potential DNA extraction) or archiving purposes. Sebaceous fingerprints and those made after perspiring were detected based on elements such as potassium and chlorine present in the print residue. Unique prints were also detected including those containing lotion, saliva, banana, or sunscreen. This proof-of-concept study demonstrates the potential for visualizing fingerprints by MXRF on surfaces that can be problematic using current methods.     

Taphonomy of child-sized remains: a study of scattering and scavenging in Virginia, USA

Child-sized pig carcasses (Sus scrofa) were placed in surface deposit and buried scenarios in a wooded area of Virginia from May 1998 through December 2000, to examine the taphonomic effects of decompositional changes, predator scavenging, and the extent of remains scattering. Changes were observed through on-site examination, charting of remains, and recorded video imaging. Analysis of data revealed that utilization of corpses as food sources by vertebrates was dependent upon invertebrate colonization. Vertebrates avoided feeding on the corpses while invertebrate colonization was active, and would feed before invertebrates successfully colonized a corpse, or would wait until the invertebrate populations migrated away from the corpse. Among vertebrates, there was no apparent succession order for the animals utilizing the remains as a food source. Different vertebrates would feed at different times based upon diurnal or nocturnal predilection. Analysis noted an accidental cooperative relationship between the invertebrates and vertebrates scavenging on the corpses. Certain vertebrates gained access to the internal tissues by utilizing openings in the corpses caused by invertebrate and other vertebrate scavenging. Alternately, carrion-frequenting insects were afforded access to previously inaccessible colonization sites as a result of scavenging vertebrate activities.     

Lead-free primer residues: a qualitative characterization of Winchester WinClean, Remington/UMC LeadLess, Federal BallistiClean, and Speer Lawman CleanFire handgun ammunition

The elemental composition and postfiring residues of several "lead-free" or "nontoxic" centerfire handgun ammunition types currently available to the general public were examined. Offerings from Winchester, Remington/UMC, Federal and Speer were obtained from retail sources in both .45 ACP and 9 mm when possible. A total of 112 postfiring residue samples (SEM pins) were collected at varying distances from the muzzle, at two distances from target and from the shooter's hands. An additional 20 samples were collected by direct ignition of primers. Qualitative determinations were carried out using scanning electron microscopy (SEM)/electron dispersive spectrometry (EDS) analysis. All types tested contained aluminum (Al), silicon (Si), copper (Cu), and zinc (Zn). Most contain traces of sulfur and calcium. Winchester WinClean and Remington LeadLess contained potassium as the principle ingredient. Federal BallistClean contained barium, while Speer Lawman CleanFire contained strontium. In the main, these compared favorably with manufacturers' MSDS publications and patents granted. The characterizations undertaken here will be of use to the forensic electron microscopist as these formulations gain popularity.     

Elemental analysis of human cremains using ICP-OES to classify legitimate and contaminated cremains

The Tri-State Crematory Incident in Nobel, GA (February 2001) revealed limitations in traditional human cremated remains (cremains) analytical methodology. The goal of this study was to develop a method for effectively classifying questionable sets of cremains as legitimate or contaminated. Eighty-eight samples of known human cremains, concrete, mixtures of the two, and questionable sets of cremains were acid digested and analyzed for 21 elements by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Variable cluster and principle component analyses identified the seven elements (Sb, B, Li, Mn, Sr, Tl, and V) used to develop discriminant functions to classify questionable sets into two groups: cremains and concrete. The discriminant analysis shows that at the 0.90 probability level, mixtures of 50% or less human content were classified as concrete. Mixtures with 90% human content classified as cremains. Sixty percent and 75% human content mixtures remained in the questionable classification, but as the concentration of human increased in the mixture, the probability of assignment to the known cremains group increased. Most of the questionable human samples classified as cremains. This is a pilot study and cannot yet satisfy Daubert standards for courtroom admissibility, but it indicates that it is possible to determine the legitimacy of cremains using elemental analysis by ICP-OES coupled with multivariate statistical analysis.     

Economic incentives for the self-regulation of the release of price-sensitive information

Companies, as primary disseminators of information, and financial institutions, as major recipients, have economic incentives to self-regulate the transmission and usage of price-sensitive information. These include increased (lost) reputation costs and adverse share price penalties arising from poor management of information disclosure. The economic motivation for self-regulation is seen as conceptually linked to but distinct from legislative changes. Self-regulation has the strong support of economic efficiency arguments, whereas recent additional new legislative changes do not. This article examines a major corporate and institutional response to the new regulatory climate—to internalize part of the regulatory process during their regular relationship communications. Relationships between the case companies and institutions already exist for transaction purposes. They are used as a convenient and low-cost means to pursue self-regulation and to avoid errors of price-sensitive information release. This self-regulatory process is illustrated using case material. It is clear from the response pattern presented that the development of a self-regulatory framework by the parties has been an iterative one. The corporate and institutional systems that have been evolving seem to be significantly influenced by the regulatory trends. The regulatory changes appear to have played a role in increasing market costs incurred by those companies with poor stock market communication practices. The article ends by arguing that new proposals to change in the formal regulatory system should recognize that further legislation is unlikely to improve the poor prosecution record. Nevertheless, legislative changes can combine with and buttress the self-regulation process to create an effective regulatory system.
