		Distance education has been seen as an innovation that “changes the nature of the classroom in a manner which may seem to undermine the teacher’s central role and autonomy in the instructional process and limit his/her freedom” (p.54).
		This second-class status of distance education is attributed to the fact that distance educators fail to understand the traditional academic culture that prevails in institutions of higher education.
		Distance education, to Dillon and Walsh (1992), has failed to become integrated into the academic culture, not as a result of the commonly cited factors of cost and faculty resistance, but rather due to the insistence of distance educators on perpetuating a culture that is out of touch with the driving force of higher education.

		The impractical unit for resistivity is the second and therefore the units for resistance are ohm=s/cm.
		In the case of ohmic resistors, the conversion is to heat; for antennas and light-emitting devices, the conversion is to electromagnetic radiation.
		The resistance is the ratio of the electric field strength in V/m to the magnetic field strength in A/m.

	Levers and Torque
		In a class two lever the force of the effort multiplied by the distance of the effort from the fulcrum is opposite and equal to the force of the resistance multiplied by the distance of the resistance from the fulcrum.
		In a class three lever the resistance is between the force of the effort and the fulcrum.
		In a class three lever the force of the effort multiplied by the distance of the effort from the fulcrum is opposite and equal to the force of the resistance multiplied by the distance of the resistance from the fulcrum.

	Information on business distance degrees
		This resistance, which is the outcome of numerous, individual decisions based on self-interest or personal constraints, is evident in many markets.
		When considering attitudes to distance degrees, resistance—or hesitancy—is understandable given the amount of money, time, commitment, and effort required to complete a distance degree weighed against a fear that one's hard-earned qualification might not be held in high regard.
		Completing a distance degree is no easy task (dropout rates are high) and they are not cheap, but to conclude that a distance degree is not as good as an on-campus degree is wrong.

	The Death of Distance: Documenting the Effects of Distance Education In South Dakota
		Using this framework in a contemporary context, it is clear that resistance to technology in general, and technology supported learning in particular, may be rooted in the collective and individual identity of those the technology has the potential to affect.
		Resistance to distance education occurs when students perceive that they are being offered a second rate service, or where fear of the technology is present.
		Resistance through drop-out is often attributable to these issues but the most important factor influencing attrition for the authors, is the lack of social support remote learners can experience.

	Jim Marston Dissertation Chapter 4.5
		Subjects considered a distance of one block (from the same block transfer to the one block transfer), the entire three blocks (the difference between the same block times and the three block times), and the last two blocks (the difference from the one block times and the three block times).
		The variation in mean distance resistance between the three groups was previously examined, but there also exists a variation in how increased distance affects their perceived resistance to walk.
		The perceived reduction in blind users’ resistance, when considering RIAS, was similar to that of the sighted and indicates that the paucity of accessible identity and directional cues in the environment helps cause the increased resistance for that group, when using their regular methods.

	Re-Conceptualizing Intimacy and Distance in Instructional Models
		The idea that distance education lacks intimacy and is therefore inferior is based on an embedded metaphor that sustains a restricted and limiting mental model of ideal instruction.
		Distance metaphors are so fundamental that they are the basis for other kinds of metaphors in a developmental sequence from concrete to abstract thought.
		Moore considered the physical distance and learner autonomy to be measurable, and he proposed that differences in two-way communication, or dialog, and differences in responsiveness (structure) to individual needs could account for differences in satisfaction, and along with learner autonomy, also account for the degree to which a student can function without supervision.

		The resistance R to the movement of charge in a potential gradient is related to current I by Ohm’s law.
		Thus R is not a constant for a given material and depends on the distance through which the current is passed.
		This is due to increased movement of the lattice and a greater frequency of collisions between the moving electrons and the lattice.

	Faculty Development
		In the administration of distance education services which are instructor-led, the quality of the instructor seems to be as important as in a traditional classroom setting.
		They noted that typical distance education faculty must be able to run both the cameras and still do most of the teacher in a distance education course.
		The root of this resistance lies in negative perceptions of the instructor's role in distance education.

		Since the effort distance is twice the resistance distance, the effort must be half the resistance.
		The distance between point where the wheel touches the ground (in a wheel on a vehicle) and the point about which the wheel turns is the resistance arm.
		Since these distances will be equal to the radius of the axle and the radius of the wheel, the ratio of these two will be equal to the mechanical advantage (MA = radius of axle/radius of wheel).

	Distance Learning
		Distance Learning has emerged in North American education in the last decade as a major delivery method of education, losing a previous stigma attached to "Correspondence Course" education.
		Distance learning is now also common in the field of occupational education.
		Distance Learning is especially well-suited to the study of medical herbalism and clinical nutrition, since these topics are taught in a relatively small number of locations in the country, and the great majority of individuals wanting this education cannot relocate to acquire it.

		The mechanical advantage of a lever is the ratio of the length of the arc on the effort side to the length of the arc on the resistance side (whew, that sounds technical J).
		When the fulcrum is closer to the resistance force (resistance arm less than effort arm), the effort force is increased, but there is a corresponding decrease in both the distance the resistance force moves and the speed with which it moves.
		Conversely, when the fulcrum is closer to the effort force (resistance arm > effort arm), the resistance force is decreased and there is a corresponding increase in both the distance the resistance moves and the speed with which it moves.

	The Transformation of Education
		While distance education as a method of delivering instruction has become more widespread and more accepted, traditional education will continue to be the most widely used delivery method in the United States.
		A more substantial hurdle for distance education is the resistance from the establishment and culture that has grown up with America's model of traditional education, even in light of the evidence of the effectiveness of distance education.
		A parallel event to the development of applicable distance education theory and the training of distance educator is the incorporation of technology in the traditional classroom.

	Simple Machines
		The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum.
		The class of a lever is determined by the location of the applied and resistance forces relative to the fulcrum.
		When the fulcrum is located closer to the resistance than to the force, an increase in force (mechanical advantage) results.

	RECRUITING Distance Learning : December 2002 : THE Journal (Site not responding. Last check: 2007-10-11)
		This resistance to distance learning has mostly been centered around the loss of personal interaction between the instructor and the student (Carnevale 2001).
		There is an inherent assumption in distance learning that any relationship that is established between a student and an instructor by virtue of the traditional classroom environment will be lost in a distance learning format.
		Distance learning programs are much more readily supported when the overall objective is at least, in part, making educational opportunities available to those not easily served.

		Its operation is the reverse of that of the electric generator, which transforms the energy of falling water or steam into electrical energy.
		Ideally, the two ratios are equal, and it is simpler to calculate the ratio of the distance the effort moves to the distance the resistance moves; this is called the ideal mechanical advantage (IMA).
		The efficiency of a machine is equal to the ratio of its output (resistance multiplied by the distance it is moved) to its input (effort multiplied by the distance through which it is exerted); it is also equal to the ratio of the AMA to the IMA.

		Abstract: We study the resistance distance on connected undirected graphs, linking this concept to the fruitful area of random walks on graphs.
		We provide two short proofs of a general lower bound for the resistance, or Kirchhoff index, of graphs on N vertices, as well as a general formula to compute it exactly, whose complexity is that of inverting an N \Theta N matrix.
		We argue that the formulas for the resistance in the case of the Platonic solids can be generalized to all distance-transitive...

		It therefore follows that combining two types of training – such as resistance and endurance training – is likely to interfere with the training response induced by either type of training alone.
		A study published in 1980 first provided evidence for the existence of an ‘interference effect’ between resistance and endurance training by demonstrating that strength gains were hindered when the two types of training were performed concurrently.
		All subjects were measured before and after the training period for: weight; percentage body fat; peak oxygen consumption (V02max); isokinetic peak torque and average power produced during single-leg flexion and extension at 60 and 180°; one-repetition maximum leg press and bench press; vertical jump height and calculated jump power.
