Review of periodical articles

[First Paragraph] There is only one true city, wrote St Augustine, and it is not of this world. The pessimistic Christian response to the fall of Rome in AD 410, epitomized in Augustine's City of God, affected the development of the later medieval city to a degree which has yet, even now, to be fully appreciated. In the Christian city of the Middle Ages the divinity was normally confined to the sanctuaries of his churches, whose topographical prominence and harmonious proportions made manifest an otherwise hidden spiritual order. Outside the cloister gates, disorder reigned: a general lack of planning revealed the meaninglessness of the outward, secular life. This dichotomy between an inner world of spirit and a public world of transient matter was embodied in the recurrent tensions between spiritual and secular space which ran as a motif throughout the history of medieval towns. Modern studies which have emphasized (not, of course, without reason) the secular political and economic power of ecclesiastical institutions in the medieval city have perhaps distracted attention unduly from the real differences of ethos which, within the town, distinguished religious space from that of the surrounding lay world

Review of periodical articles

One of the attractions of medieval urban history is the fact that major conceptual problems in the field continue to be debated. In a stimulating review article by J.H. Mundy, ’Philip Jones and the medieval Italian city-state‘, J. of European Economic History, 28 (1999), 185–200, one distinguished scholar is taxed for holding views now dismissed by some, but of which he is by no means a unique surviving representative. One of these views assumes a clear distinction between the antique city, supposedly a bureaucratic centre with limited economic functions, and the medieval city, as the home of industrious artisans and nascent capitalism. The image of the non-profit-making ancient town may be overly indebted to the nature of the literary sources and to the prevalent interests of classicists; but, although many would now agree that both the elements in the above equation need qualifying, a more focused comparison is presently lacking, and a fine book is still waiting to be written on the transition from the ancient world to the middle ages in urban history

Formissional worship: curriculum design and delivery

The purpose of this study was to measure the cognitive, attitudinal, and behavioral changes in students concerning formissional worship as a result of a Master of Ministry class at Mount Vernon Nazarene University entitled Christian Worship. The scriptural foundation was the Shema (Deut. 6:4-5), quoted by Jesus in the Greatest Commandment (Matt. 22:37-40; Mark 12:29-31). The curricular outline was worship as invitation, revelation, participation, formation, contextualization, incarnation, and integration. The instruments used to gather data from the students were two surveys and an online threaded discussion by the students during class. The surveys framed the class as a pre- and posttest, while the process element of the weekly postings was embedded between. The research indicated a renewed awareness among the students of God’s divine initiative in worship. Keeping God’s word central was found to form worship leader and worshiper alike in preparation for, presentation of, and participation in communal worship. The participants affirmed that God’s mission is realized as Spirit-filled leaders embody missional worship, moving outward from God’s altar. The belief that through this inside out movement, each church speaks into a particular context was strengthened over the course of the class. The respondents endorsed more strongly that the integration of worship, mission, and spiritual formation leads the disciple to a lifestyle of formissional worship.https://place.asburyseminary.edu/ecommonsatsdissertations/1561/thumbnail.jp

A Number-Theoretic Error-Correcting Code

In this paper we describe a new error-correcting code (ECC) inspired by the Naccache-Stern cryptosystem. While by far less efficient than Turbo codes, the proposed ECC happens to be more efficient than some established ECCs for certain sets of parameters. The new ECC adds an appendix to the message. The appendix is the modular product of small primes representing the message bits. The receiver recomputes the product and detects transmission errors using modular division and lattice reduction

Cloning, sequencing, and characterization of the hexahydro-1,3,5-trinitro-1,3,5-triazine degradation gene cluster from Rhodococcus rhodochrous

Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a high explosive which presents an environmental hazard as a major land and groundwater contaminant. Rhodococcus rhodochrous strain 11Y was isolated from explosive contaminated land and is capable of degrading RDX when provided as the sole source of nitrogen for growth. Products of RDX degradation in resting-cell incubations were analyzed and found to include nitrite, formaldehyde, and formate. No ammonium was excreted into the medium, and no dead-end metabolites were observed. The gene responsible for the degradation of RDX in strain 11Y is a constitutively expressed cytochrome P450-like gene, xpLA, which is found in a gene cluster with an adrenodoxin reductase homologue, xplB. The cytochrome P450 also has a flavodoxin domain at the N terminus. This study is the first to present a gene which has been identified as being responsible for RDX biodegradation. The mechanism of action of XplA on RDX is thought to involve initial denitration followed by spontaneous ring cleavage and mineralization
