Research Without Old Data and Old References

 

Background: The use of older data and references is becoming increasingly disfavored for publication. A myopic focus on newer research risks losing sight of important research questions already addressed by now-invisible older studies. This creates a ‘Groundhog Day’ effect as illustrated by the 1993 movie of this name in which the protagonist has to relive the same day (Groundhog Day) over and over and over within a world with no memory of it. This article examines the consequences of the recent preference for newer data and references in current publication practices and is intended to stimulate new consideration of the utility of selected older data and references for the advancement of scientific knowledge.

Methods: Examples from the literature are used to exemplify the value of older data and older references. To illustrate the recency of references published in original medical research articles in a selected sample of recent academic medical journals, original research articles were examined in recent issues in selected psychiatry, medicine, and surgery journals.

Results: The literature examined reflected this article’s initial assertion that journals are emphasizing the publication of research with newer data and more recent references.

Conclusions: The current valuation of newer data above older data fails to appreciate the fact that new data eventually become old, and that old data were once new. The bias demonstrated in arbitrary policies pertaining to older data and older references can be addressed by instituting comparable treatment of older and newer data and references.

LIVE: ABER Radio

The station was established in 1977, long before the advent of internet radio, with the goal of providing students a platform for creative expression, entertainment, and community involvement. Initially, it operated as a small, pirate-style radio station, broadcasting on a limited basis to the university campus. It mainly aired music and student-related content. Over time, the station evolved to include news, talk shows, and interviews, becoming an important part of student life and a voice for the university community.

In the early 1980s, after gaining recognition, the station was granted a temporary Restricted Service Licence (RSL) by Ofcom. This allowed it to broadcast legally on an official frequency for short periods. During this time, the station used various FM frequencies, with the exact frequency changing depending on licensing terms and specific broadcast periods.

In the 1990s, ABER Radio received an official license, enabling it to expand its reach and professionalize its operations. With this transition, the station began broadcasting online, offering a diverse range of programming from music and entertainment to news and current affairs. It also provided students with valuable experience in radio production, journalism, and broadcasting.

Stray Voltage: Sources and Solutions

Truman C. Surbrook – Norman D. Reese – Angela M. Kehrle

 

Abstract.  Stray voltage is caused by voltage drop and ground faults and may have its origin on the primary electrical distribution system or on the customer’s secondary electrical system. The rms value of the neutral-to-earth voltage along a primary distribution line may be at a value of zero some distance from the substation depending on the condition of the conductor resistances, grounding resistances, and the amount of load. Neutral-to-earth resistance is not the cause of stray voltage; however, the value of this resistance to earth at a particular location will affect the level of stray voltage. A four-wire single-phase feeder system supplying farm buildings from a single metering point is effective in preventing on-farm secondary neutral voltage drop, provided the four-wire system is extended to all farm loads, and provided no high-magnitude ground faults are present. Isolation of the primary and secondary neutral systems at the distribution transformer is effective in preventing off-farm sources from entering the customer’s system. This separation may be accomplished using a number of commercially available devices.
