Re-engineering Technology: Date Mining for Clubs

With increasing competition and more demanding members, clubs need a tool to help them belter attract and retain members and predict their behavior. Data mining is such a tool. This article presents an overview of how data warehousing, data marting, and data mining can provide the foundation on which clubs can build strategies to outsmart competitors, build Ioyalty identify new members, and lower costs.

Composition date of the synoptic gospels

The purpose of this research paper is to follow a line of ongoing investigations that discuss dates for the origin of the synoptic gospels and evaluate the arguments for early, late, and intermediate dating and their susceptibility to critique from opposing arguments. There are three principal components in dating theories: (1) data from the Greek in the earliest texts (2) data concerning the provenance of the earliest texts (3) and data from the historical context of the first century. The study is significant because, contrary to what might be expected, the starting and key point in deciding on a composition date is the Book of Acts of the Apostles. This study compiled and integrated information, in an unbiased fashion, based on reading and researching large numbers of texts by scholars, such as Hengel, who support an earlier dating, as well as those, such as Fitzmyer, who support a later dating. Furthermore, this study also required knowledge of those scholars who propose dates that do not fall into these main categories. The research demonstrated that by looking at the Book of Acts of the Apostles as the key starting point, the synoptic gospels were most likely composed before 70 CE, therefore, supporting scholars who argue for an earlier date.

High-performance liquid chromatography (HPLC) and high-performance liquid chromatography mass spectrometry (HPLC/MS) for the analysis of date rape drugs

The drugs studied in this work have been reportedly used to commit drug-facilitated sexual assault (DFSA), commonly known as "date rape". Detection of the drugs was performed using high-performance liquid chromatography with ultraviolet detection (HPLC/UV) and identified with high performance-liquid chromatography mass spectrometry (HPLC/MS) using selected ion monitoring (SIM). The objective of this study was to develop a single HPLC method for the simultaneous detection, identification and quantitation of these drugs. The following drugs were simultaneously analyzed: Gamma-hydroxybutyrate (GHB), scopolamine, lysergic acid diethylamide, ketamine, flunitrazepam, and diphenhydramine. The results showed increased sensitivity with electrospray (ES) ionization versus atmospheric pressure chemical ionization (APCI) using HPLC/MS. HPLC/ES/MS was approximately six times more sensitive than HPLC/APCI/MS and about fifty times more sensitive than HPLC/UV. A limit of detection (LOD) of 100 ppb was achieved for drug analysis using this method. The average linear regression coefficient of correlation squared (r2) was 0.933 for HPLC/UV and 0.998 for HPLC/ES/MS. The detection limits achieved by this method allowed for the detection of drug dosages used in beverage tampering. This method can be used to screen beverages suspected of drug tampering. The results of this study demonstrated that solid phase microextraction (SPME) did not improve sensitivity as an extraction technique when compared to direct injections of the drug standards.
