I like to think of this as fiction for the restless. The restlessly creative mind is a little capricious; a little impetuous; a little bizarre. Above all else, it is fun. Beyond the Threshold will offer regular doses of speculative flash fiction (1000 words or less), designed to satisfy those who crave the short, the sweet, and the strange. In the same vein of brevity, flash book reviews of speculative fiction will also abound.
One subset of responses to the Framework has made suggestions for improvement or requested clarification. These criticisms generally accept the Framework on its own terms and are concerned with its practicality, implementation, adaptability, and accessibility. People ask how the Frames or the threshold concepts upon which they are based will work in practice, what challenges will be posed by adopting the Framework, how different it will be from the Standards in this respect, and how librarians, faculty, and administrators will be convinced to replace explicit Standards with a set of guidelines that are less prescriptive.7
While the framework does an admirable job of showing how threshold concepts can help shift information literacy toward a pedagogy that stresses the development of self-critical and self-conscious learning in the student, it does not state as its goal the formation of possible solidarities for the student to help change the information system itself, nor the hierarchies of knowledge and status within academia. Furthermore, by continuing to stress the individual learner, it obscures the fact that any real change would actually require collective understanding and action rather than individualized learning. In this way the Framework continues to do the work that the Standards were doing all along. But the vital difference between the two, perhaps, is the enhanced opportunities for critical interventions that the Framework provides and even encourages.18
The absolute threshold is an important tool for researchers studying the capabilities and limitations of human sensation and perception. It is defined as the lowest stimulus level that an organism can detect at least half the time. These limits can vary depending on factors such as motivation, expectation, and attention. In other words, there is no single absolute threshold for any sensory experience. It may vary from person to person and from one situation to the next.
During each trial, you would signal when you are first able to detect the presence of light. The smallest level that you are able to detect half of the time is your absolute threshold for light detection.
The absolute threshold for smell can vary considerably depending upon the type of odor used, the dilution methods, the data collection methods the researchers are utilizing, environmental factors, and individual characteristics. For example, one study found that certain personality traits can influence how we detect scents.
Absolute thresholds aren't constant; they are prone to change as we grow older. When we are younger, we can detect things at lower levels. As we age, however, we begin to need increased stimulation to detect those same sensory events.
The difference threshold is the minimum difference between two stimuli that is detectable. Like the absolute threshold, the difference threshold is the minimum difference that can be detected at least 50% of the time.

When the thought of lust or whatever our individual strongholds pass the threshold of the mind and enter the mind (thinker), it and we begin to consider the possibilities of the act or fantasize, then our emotions (feelers) come into the picture and we insert that into the equation. The mind is thinking about it and the emotions are having feelings about it, but what happens next? A decision must be made and then the will or decider part of our personality comes into play. You see, the spiritual battles are won and lost on the threshold of the mind before they enter the mind where the emotions and will reinforce the mind and cause defeat for most of us.
Ultimately there is only one solution. We must be transformed by the renewal of our minds and understand the old self died when we were crucified with Christ. Understand who you are in Christ. You are a spiritual being now with the Spirit of God living in you. If we are to have the abundant life our Father desires for us, we must accept these events by faith. Change your thinking and visualize who and where you are; a child of God seated in heaven at the right hand of your real Father in Christ. And that is where we must set our minds, not on the things of this earth, for we died when He died.
Throughout the Holocene, societies developed additional layers of administration and more information-rich instruments for managing and recording transactions and events as they grew in population and territory. Yet, while such increases seem inevitable, they are not. Here we use the Seshat database to investigate the development of hundreds of polities, from multiple continents, over thousands of years. We find that sociopolitical development is dominated first by growth in polity scale, then by improvements in information processing and economic systems, and then by further increases in scale. We thus define a Scale Threshold for societies, beyond which growth in information processing becomes paramount, and an Information Threshold, which once crossed facilitates additional growth in scale\u2026 We also suggest a mechanism to help explain social collapses with no evident external causes.
When a society hits the information scaling threshold, it stalls out. It can\u2019t function until it invents new ways of making sense that can cope with the complexity of the information environment. And societies that don\u2019t pull off this transition? The paper posits they collapse.
The timing here seems unfortunate. We\u2019re facing planetary challenges: climate change, global pandemics, mass extinctions, increasing geopolitical tension, financial crises, looming nuclear threats\u2026 What a time to be hitting the information scaling threshold!
But, then, maybe the information scaling threshold is why we\u2019re experiencing these crises in the first place? As our problems get more complex, our ability to meaningfully coordinate breaks down.
Both egregores and AIs are intelligences that can only arise when you reach the information complexity of today\u2019s internet. What if the information environment that pushed us into the scaling threshold births intelligences that can help us think beyond, to the next level?
One thing seems certain: we need to pass beyond the information scaling threshold. This means finding new ways to think together with the internet. And a future where we own our second brains seems brighter than one where we don\u2019t.
Wild type populations of Drosophila melanogaster were exposed to 21%, 33%, 45%, and 55% oxygen at normal atmospheric pressures. Individuals were selected randomly at 5-d intervals and inspected for vacuolation of the forebrain. Longevity of the populations was also measured. Flies in 21% and 33% oxygen had identical survivorship and even after 50 d showed little vacuolation. Flies maintained in 45% oxygen showed rapid mortality between 30-40 d and were found to have vacuolated forebrains. Populations treated in 55% oxygen declined rapidly in numbers between 20-30 d and showed severe vacuolation of the forebrain. It was considered important that normal longevity and normal aging of brain cells in 33% oxygen at standard pressure were found because similar partial pressures of pure oxygen were reported to significantly reduce longevity. It is suggested that, because insects are known to be tolerant to fairly extreme changes in total atmospheric pressure, a partial pressure of nitrogen as a diluent gas is the important factor in the toxic effects of a given pressure of oxygen. The study indicates that in a nitrogen/oxygen mix at 760 torr total pressure, the threshold to toxicity lies near, or just beyond, 300 torr oxygen. The authors indicate that preliminary findings in their current work show that if a small partial pressure of nitrogen is maintained, the total pressure can be reduced considerably without affecting this threshold level.
When a flashed stimulus is followed by a backward mask, subjects fail to perceive it unless the target-mask interval exceeds a threshold duration of about 50 ms. Models of conscious access postulate that this threshold is associated with the time needed to establish sustained activity in recurrent cortical loops, but the brain areas involved and their timing remain debated. We used high-density recordings of event-related potentials (ERPs) and cortical source reconstruction to assess the time course of human brain activity evoked by masked stimuli and to determine neural events during which brain activity correlates with conscious reports. Target-mask stimulus onset asynchrony (SOA) was varied in small steps, allowing us to ask which ERP events show the characteristic nonlinear dependence with SOA seen in subjective and objective reports. The results separate distinct stages in mask-target interactions, indicating that a considerable amount of subliminal processing can occur early on in the occipito-temporal pathway (270 ms) and highly distributed fronto-parieto-temporal activation as a correlate of conscious reportability.
As a second independent criterion for a cerebral correlate of conscious access, we asked which ERP components varied with subjective reports when the visual stimulus was fixed. To this aim, we examined the trials with an SOA of 50 ms, close to the conscious threshold, and sorted them as a function of whether the subject reported seeing the target or not (three subjects had to be excluded from this analysis because they did not have enough observations in one of these two categories). The only significant difference between seen and not-seen trials was again found on the target-evoked P3 component (Table 1). As shown in Figure 7, on central electrodes, seen and not-seen trials initially generated identical activity, but a divergence was seen starting around 300 ms, with seen trials generating an increased positivity. This difference was quite similar to the nonlinear divergence observed on the same electrodes as a function of SOA (compare Figures 6 and 7). Thus, both criteria clearly point to the P3 as an important correlate of conscious perception.
