一般行政规范性文件质量监控制度研究

一般行政规范性文件在我国行政管理中起着非常重要的作用,但有些一般行政规范性文件存在严重不合理、甚至违法的情况。现行的各种监督制度由于存在内在的逻辑上缺陷,基本上不能发挥监督作用。我们需要以加强事前监督为重点,完善司法审查制度为保障,重构一般行政规范性文件监督审查制度。

An Examination of the Sequence of Intersecting Lines using Microspectrophotometry

The potential of microspectrophotometry as a technique to determine the sequence of intersecting lines was examined. The technique was used to determine the sequence of heterogeneous line intersections produced using inkpad, stamp‐pad ink and ballpoint pens, gel pens, fountain pens, laser and ink‐jet printers. The study was carried out with an assumption that the peak characteristics of spectra from the point of intersection should correspond to the peak characteristics of pure ink which was executed later. According to spectral reflectance curves, microspectrophotometry was possible to determine whether the ink was above or below the inkpad/stamp‐pad ink seals. In blind testing, microspectrophotometry technique results were directly compared to those obtained by five experienced forensic document examiners using optical microscopy regularly employed in casework. As the results obtained from the study were positive, microspectrophotometry technique was found to be very successful in determining the sequence of heterogeneous line intersections under some conditions.     

Characterization of Printing Inks Using DART‐Q‐TOF‐MS and Attenuated Total Reflectance (ATR) FTIR

The rise in improved and widely accessible printing technology has resulted in an interest to develop rapid and minimally destructive chemical analytical techniques that can characterize printing inks for forensic document analysis. Chemical characterization of printing inks allows for both discrimination of inks originating from different sources and the association of inks originating from the same source. Direct analysis in real‐time mass spectrometry (DART‐MS) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR‐FTIR) were used in tandem to analyze four different classes of printing inks: inkjets, toners, offset, and intaglio. A total of 319 samples or ~ 80 samples from each class were analyzed directly on a paper substrate using the two methods. DART‐MS was found to characterize the semi‐volatile polymeric vehicle components, while ATR‐FTIR provided chemical information associated with the bulk components of these inks. Complimentary data results in improved discrimination when both techniques are used in succession resulting in >96% discrimination for all toners, 95% for all inkjets, >92% for all offset, and >54% for all intaglio inks.     

Evaluation of the Forensic Utility of Scanning Electron Microscopy‐Energy Dispersive Spectroscopy and Laser Ablation‐Inductively Coupled Plasma‐Mass Spectrometry for Printing Ink Examinations

Improvements in printing technology have exacerbated the problem of document counterfeiting, prompting the need for analytical techniques that better characterize inks for forensic analysis and comparisons. In this study, 319 printing inks (toner, inkjet, offset, and Intaglio) were analyzed directly on the paper substrate using scanning electron microscopy‐energy dispersive spectroscopy (SEM‐EDS) and Laser Ablation‐Inductively Coupled Plasma‐Mass Spectrometry (LA‐ICP‐MS). As anticipated, the high sensitivity of LA‐ICP‐MS pairwise comparisons resulted in excellent discrimination (average of ~ 99.6%) between different ink samples from each of the four ink types and almost 100% correct associations between ink samples known to originate from the same source. SEM‐EDS analysis also resulted in very good discrimination for different toner and intaglio inks (>97%) and 100% correct association for samples from the same source. SEM‐EDS provided complementary information to LA‐ICP‐MS for certain ink types but showed limited utility for the discrimination of inkjet and offset inks.

Planning and Control System With a Network Approach： Evidence From the Italian Regional Governments

The focus on networks in public administration has grown rapidly in recent years and prompts modifications of traditional planning and control systems of public entities. Public networks have been defined as a response to the criticalities of New Public Management and they represent a recurring approach for policy implementation and service provision in the theoretical framework known as New Public Governance. This article addresses the question whether public entities are aware of being part of a network and whether they have actually changed, as such, their planning and control system. Focus is made on the case of Italian regional governments which are particularly significant for different reasons. First of all, the recent process of administrative devolution and federalism in Italy has reinforced regional governments＇ powers and responsibilities as well as their importance as actors in the political and economic scenario, where they can influence the behaviours of many public and private organizations. Furthermore, Italian regional governments have extensive autonomy and so they can actually modify and integrate traditional documents of their planning and control system. The article proposes a framework for mapping different approaches toward being part of a public network. This framework can support the interpretation of the behaviour of public entities involved in networks and take the initiatives to develop them.     

Measuring the Frequency Occurrence of Handwriting and Handprinting Characteristics,

The premise of this study was to take a valid population sampling of handwriting and handprinting and assess how many times each of the predetermined characteristic is found in the samples. Approximately 1500 handwriting specimens were collected from across the United States and pared to obtain a representative sample of the U.S. adult population according to selected demographics based on age, sex, ethnicity, handedness, education level, and location of lower‐grade school education. This study has been able to support a quantitative assessment of extrinsic and intrinsic effects in handwriting and handprinting for the six subgroups. Additional results include analyses of the interdependence of characteristics. This study found that 98.55% of handprinted characteristics and 97.39% of cursive characteristics had an independence correlation of under 0.2. The conclusions support use of the product rule in general, but with noted caveats. Finally, this study provides frequency occurrence proportions for 776 handwriting and handprinting characteristics.     

Ballpoint pen inks: the quantitative analysis of ink solvents on paper by solid-phase microextraction

We wish to describe further developments to a method previously reported on the detection of 2-phenoxyethanol in ink. The solid-phase microextraction (SPME) sampling technique, together with gas chromatography-mass spectrometry (GC-MS), has been used to quantify solvents in writing ink. In conventional approaches, the analysis of ink on documents requires some degree of destructive sampling. The methods commonly used remove ink samples from paper using a scalpel or a paper punch. To avoid document destruction, a sampling cell was constructed that allows solvents to be adsorbed directly onto the SPME fiber from the headspace above the document surface. Analytes (ink volatiles) are then desorbed from the SPME fiber on a gas chromatograph equipped with a mass selective detector (GC-MSD). With this method, it was possible to detect the presence of ink solvents on documents for a period lasting up to c. 2 years.
